Overview

Selective Insurance Group, Inc. (referred to as the “Parent”) is a New Jersey holding company that was incorporated in 1977. Our main office is located in Branchville, New Jersey and the Parent’s common stock is publicly traded on the NASDAQ Global Select Market under the symbol “SIGI.” The Parent has ten insurance subsidiaries, nine of which are licensed by various state departments of insurance to write specific lines of property and casualty insurance business in the standard market. The remaining subsidiary is authorized by various state insurance departments to write property and casualty insurance in the excess and surplus ("E&S") lines market. Our ten insurance subsidiaries are collectively referred to as the “Insurance Subsidiaries.” The Parent and its subsidiaries are collectively referred to as "we," “us,” or “our” in this document.

In 2016 we celebrated our 90^th year in business. Over the years, we have transformed ourselves into a super-regional property and casualty insurance company with the customer service capabilities, product offering, and technical know-how of a national carrier.

In 2016, we were ranked as the 41^st largest property and casualty group in the United States based on 2015 net premiums written (“NPW”) in A.M. Best Company’s (“A.M. Best”) annual list of “Top 200 U.S. Property/Casualty Writers.”

The property and casualty insurance market is highly competitive, with fragmented market share and three main distribution methods: (i) sales through independent insurance agents; (ii) direct sales to personal and commercial customers; and (iii) a combination of independent agent and direct sales. In this highly competitive and regulated industry, we think we have three principal strategic advantages. The first is the true franchise value we have with our independent distribution partners, who collectively have significant market share in the states in which we operate and from whom we expect to gain increasing percentages of the business they write. The second is our unique field model, in which our underwriting, claims, and safety management personnel are located in the same communities as our distribution partners and customers supported by sophisticated analytics, technology, and regional and home office support. The third is our focus on customer service and providing an exceptional and personalized omni-channel 24/7 customer experience, which is less common in the marketplace for commercial customers and more so for personal customers.

Based on these three principal strategic advantages, we have a financial goal to achieve an operating return on equity that is at least three percentage points higher than our weighted-average cost of capital over time. For further details regarding our 2016 performance as it relates to return on equity, refer to "Financial Highlights of Results for Years Ended December 31, 2016, 2015, and 2014" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

Furthermore, Financial Strength Ratings play a significant role in insurance purchasing recommendations by our distribution partners and in decision-making by our customers. Distribution partners generally recommend higher rated carriers to limit their liability for error and omission claims, and customers often have minimum insurer rating requirements in loan and other banking covenants securing real and personal property. Our Insurance Subsidiaries’ ratings by major rating agency are as follows:



Rating Agency	Financial Strength Rating	Outlook
A.M. Best	A	Stable
Standard & Poor’s Global Ratings (“S&P”)	A	Stable
Moody’s Investors Services (“Moody’s”)	A2	Stable
Fitch Ratings (“Fitch”)	A+	Stable

For further discussion on our ratings, please see the “Ratings” section of Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” of this Form 10-K.

We have provided a glossary of terms as Exhibit 99.1 to this Form 10-K, which defines certain industry-specific and other terms that are used in this Form 10-K.

Segments

We classify our business into four reportable segments, which are as follows:


•	Standard Commercial Lines, which is comprised of insurance products and services provided in the standard marketplace to commercial enterprises, which are typically businesses, non-profit organizations, and local government agencies. This business represents 78% of our total insurance segments’ NPW and is sold in 22 Eastern and Midwestern states and the District of Columbia.

•

Standard Personal Lines, which is comprised of insurance products and services provided primarily to individuals acquiring coverage in the standard marketplace. This business represents 13% of our total insurance segments’ NPW and is primarily sold in 13 Eastern and Midwestern states and the District of Columbia. Standard Personal Lines includes flood insurance coverage. We are the sixth largest writer of this coverage through the National Flood Insurance Program (“NFIP”) and write flood business in all 50 states and the District of Columbia.


•	E&S Lines, which is comprised of insurance products and services provided to customers who have not obtained coverage in the standard marketplace. We currently only write commercial lines E&S coverages and this business represents 9% of our total insurance segments’ NPW and is sold in all 50 states and the District of Columbia.


•	Investments, which invests the premiums collected by our insurance segments, as well as amounts generated through our capital management strategies, which includes the issuance of debt and equity securities.

We derive substantially all of our income in three ways:

•

Underwriting income/loss from our insurance segments. Underwriting income/loss is comprised of revenues, which are the premiums earned on our insurance products and services, less expenses. Gross premiums are direct premium written (“DPW”) plus premiums assumed from other insurers. Gross premiums less premium ceded to reinsurers, is NPW. NPW is recognized as revenue ratably over a policy’s term as net premiums earned (“NPE”). Expenses related to our insurance segments fall into three main categories: (i) losses associated with claims and various loss expenses incurred for adjusting claims (referred to as “losses and loss expenses”); (ii) expenses related to insurance policy issuance, such as commissions to our distribution partners, premium taxes, and other expenses incurred in issuing and maintaining policies, including employee compensation and benefits (referred to as “underwriting expenses”); and (iii) policyholder dividends.

•

Net investment income from the investment segment. We generate income from investing insurance premiums and amounts generated through our capital management strategies. Net investment income consists primarily of: (i) interest earned on fixed income investments and preferred stocks; (ii) dividends earned on equity securities; and (iii) other income primarily generated from our alternative investment portfolio.


•	Net realized gains and losses on investment securities from the investments segment. Realized gains and losses from the investment portfolios of the Insurance Subsidiaries and the Parent are typically the result of sales, calls, and redemptions. They also include write downs from other-than-temporary impairments (“OTTI”).

Our income is partially offset by: (i) expenses at the Parent that include general corporate expenses, as well as interest on our debt obligations; and (ii) federal income taxes.

We use the combined ratio as the key measure in assessing the performance of our insurance segments. Under U.S. generally accepted accounting principles (“GAAP”), the combined ratio is calculated by adding: (i) the loss and loss expense ratio, which is the ratio of incurred losses and loss expenses to NPE; (ii) the expense ratio, which is the ratio of underwriting expenses to NPE; and (iii) the dividend ratio, which is the ratio of policyholder dividends to NPE. Statutory accounting principles ("SAP") provides a calculation of the combined ratio that differs from GAAP in that the statutory expense ratio is the ratio of underwriting expenses to NPW, not NPE. A combined ratio under 100% generally indicates an underwriting profit and a combined ratio over 100% generally indicates an underwriting loss. The combined ratio does not reflect investment income, federal income taxes, or Parent company income or expense.

We use after-tax investment income and net realized gains or losses as the key measure in assessing the performance of our investments segment. Our investment philosophy includes setting certain risk and return objectives for the fixed income, equity, and other investment portfolios. We generally review our performance by comparing our returns for each of these components of our portfolio to a weighted-average benchmark of comparable indices.

Our operations are heavily regulated by the state insurance regulators in the states in which our Insurance Subsidiaries are organized and licensed or authorized to do business. In these states, the Insurance Subsidiaries are required to file financial statements prepared in accordance with SAP, which are promulgated by the National Association of Insurance Commissioners (“NAIC”) and adopted by the various states. Because of these state insurance regulatory requirements, we use SAP to manage our insurance operations. The purpose of these state insurance regulations is to protect policyholders, so SAP focuses on solvency and liquidation value unlike GAAP, which focuses on shareholder returns as a going concern. Consequently, significant differences exist between GAAP and SAP as discussed below:


•	With regard to the underwriting expense ratio: As noted above, NPE is the denominator for GAAP; whereas NPW is the denominator for SAP.


•	With regard to income or expense recognition:


•	Underwriting expenses that are incremental and directly related to the successful acquisition of insurance policies are deferred and amortized to expense over the life of an insurance policy under GAAP; whereas they are recognized when incurred under SAP.


•	Deferred taxes are recognized as either a deferred tax expense or a deferred tax benefit in income under GAAP; whereas they are recorded directly to surplus under SAP.


•	Changes in the value of our alternative investments, which are part of our other investment portfolio on our Consolidated Balance Sheets, are recognized in income under GAAP; whereas they are recorded directly to surplus under SAP and only recognized in income when cash is received.


•	With regard to loss and loss expense reserves:


•	Under GAAP, reinsurance recoverables, net of a provision for uncollectible reinsurance, are presented as an asset on the Consolidated Balance Sheets, whereas under SAP, this amount is netted within the liability for loss and loss expense reserves.


•	Under GAAP, for those structured settlements for which we did not obtain a release, a deposit asset and the related loss reserve are included on the Consolidated Balance Sheets, whereas under SAP, the structured settlement transaction is recorded as a paid loss.

The following table reconciles losses and loss expense reserves under GAAP and SAP at December 31 as follows:



($ in thousands)	2016			2015
GAAP losses and loss expense reserves – net	$	3,691,719		3,517,728
Statutory reinsurance recoverable on unpaid losses and loss expenses	(616,700		)	(556,719	)
Structured settlements	(12,127		)	(9,104	)
Statutory losses and loss expense reserves	$	3,062,892		2,951,905

The following table reconciles reinsurance recoverables under GAAP and SAP at December 31:

Provision for uncollectible reinsurance	5,500			5,700
Statutory reinsurance recoverable on unpaid losses and loss expenses	$	616,700		556,719


•	With regard to equity under GAAP and statutory surplus under SAP:


•	The timing difference in income due to the GAAP/SAP differences in expense recognition creates a difference between GAAP equity and SAP statutory surplus.


•	Regarding unrealized gains and losses on fixed income securities:


•	Under GAAP, unrealized gains and losses on available-for-sale (“AFS”) fixed income securities are recognized in equity; but they are not recognized in equity on purchased held-to-maturity (“HTM”) securities. Unrealized gains and losses on HTM securities transferred from an AFS designation are amortized from equity as a yield adjustment.


•	Under SAP, unrealized gains and losses on fixed income securities assigned certain NAIC Securities Valuation Office ratings (specifically designations of one or two, which generally equate to investment grade bonds) are not recognized in statutory surplus. However, unrealized losses on fixed income securities that have a designation of three or higher are recognized in statutory surplus.


•	Certain assets are designated under insurance regulations as “non-admitted,” including, but not limited to, certain deferred tax assets, overdue premium receivables, furniture and equipment, and prepaid expenses. These assets are recorded in the Consolidated Balance Sheets net of applicable allowances under GAAP but are excluded from statutory surplus under SAP.

•

Regarding the recognition of the liability for our defined benefit plans, under both GAAP and SAP, the liability is recognized in an amount equal to the excess of the projected benefit obligation over the fair value of the plan assets. However, changes in this balance not otherwise recognized in income are recognized in equity as a component of other comprehensive income (“OCI”) under GAAP and in statutory surplus under SAP.

Our combined insurance segments' GAAP results for the last three completed fiscal years are shown on the following table:

"Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

Insurance Segments

Overview

We derive all of our insurance operations revenue from selling insurance products and services to businesses and individuals for premium. The majority of our sales are annual insurance policies. Our most significant cost associated with the sale of insurance policies is our losses and loss expenses.

To that end, we establish losses and loss expense reserves that are estimates of the amounts that we will need to pay in the future for claims and related expenses for insured losses that have already occurred. Estimating reserves as of any given date involves a considerable degree of judgment and is inherently uncertain. We regularly review our reserving techniques and our overall amount of reserves. For disclosures concerning our unpaid losses and loss expenses, as well as a full discussion regarding our loss reserving process, see "Critical Accounting Policies and Estimates" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K. Additionally, for an analysis of changes in our loss reserves over the most recent three-year period, see Note 9. "Reserves for Losses and Loss Expenses" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

As part of our risk management efforts associated with the sale of our products and services, we use reinsurance to protect our capital resources and insure us against losses on the risks that we underwrite. We use two main reinsurance vehicles: (i) a reinsurance pooling agreement among our Insurance Subsidiaries in which each company agrees to share in premiums and losses based on certain specified percentages; and (ii) reinsurance contracts and arrangements with third parties that cover various policies that we issue to our customers. For information regarding reinsurance treaties and agreements, see "Reinsurance" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

Insurance Segments Products and Services

The types of insurance we sell in our insurance segments fall into three broad categories:


•	Property insurance, which generally covers the financial consequences of accidental loss of an insured’s real and/or personal property. Property claims are generally reported and settled in a relatively short period of time.


•	Casualty insurance, which generally covers the financial consequences of employee injuries in the course of employment and bodily injury and/or property damage to a third party as a result of an insured’s negligent acts, omissions, or legal liabilities. Casualty claims may take several years to be reported and settled.


•	Flood insurance, which generally covers property losses under the Federal Government's Write Your Own ("WYO") Program of the NFIP. Flood insurance premiums and losses are 100% ceded to the NFIP.

We underwrite our business primarily through traditional insurance. The following table shows the principal types of policies we write:



Types of Policies	Category of Insurance	Standard Commercial Lines	Standard Personal Lines	E&S Lines
Commercial Property (including Inland Marine)	Property	X		X
Commercial Automobile	Property/Casualty	X		X
General Liability (including Excess Liability/Umbrella)	Casualty	X		X
Workers Compensation	Casualty	X
Businessowners' Policy	Property/Casualty	X
Bonds (Fidelity and Surety)	Casualty	X
Homeowners	Property/Casualty		X
Personal Automobile	Property/Casualty		X
Personal Umbrella	Casualty		X
Flood¹	Flood/Property	X	X

¹Flood insurance premiums and losses are 100% ceded to the Federal Government’s WYO Program. Certain other policies contain minimal flood or flood related coverages.

Product Development and Pricing

Our insurance policies are contracts that specify our coverages - what we will pay to or for an insured upon a specified loss. We develop our coverages internally and by adopting and modifying forms and statistical data licensed from third party aggregators, notably Insurance Services Office, Inc. (“ISO”), American Association of Insurance Services, Inc. ("AAIS"), and the National Council on Compensation Insurance, Inc. ("NCCI"). Determining the price to charge for our coverages involves consideration of many variables. At the time we underwrite and issue a policy, we do not know what our actual costs for the policy will be in the future. To calculate and project future costs, we examine and analyze historical statistical data and factor in expected changes in loss trends. Additionally, we have developed predictive models for certain of our Standard Commercial and Standard Personal Lines. Predictive models analyze historical statistical data regarding our customers and their loss experience, rank our policies, or potential policies, based on this analysis, and apply this risk data to current and future customers to predict the likely profitability of an account. A model’s predictive capabilities are limited by the amount and quality of the statistical data available. As a super-regional insurance group, our loss experience is not always statistically large enough to analyze and project future costs. Consequently, we use ISO, AAIS, and NCCI data to supplement our proprietary data.

Customers and Customer Markets

We categorize our Standard Commercial Lines customers into the following strategic business units ("SBUs"):



	Percentage of Standard Commercial Lines	Description
Contractors	35%	General contractors and trade contractors
Mercantile and Services	26%	Focuses on retail, office, service businesses, restaurants, golf courses, and hotels
Community and Public Services	20%	Focuses on public entities, social services, and religious institutions
Manufacturing and Wholesale	18%	Includes manufacturers, wholesalers, and distributors
Bonds	1%	Includes fidelity and surety
Total Standard Commercial Lines	100%

We do not categorize our Standard Personal Line customers or our E&S Line customers by SBU.

The following are general guidelines that can be used as indicators of the approximate size of our customers:


•	The average Standard Commercial Lines account size is approximately $11,000.


•	The average Standard Personal Lines account size is approximately $2,000.


•	The average E&S Lines policy is approximately $3,000.

Although our average E&S Lines policy size is approximately $3,000, we have recently expanded into the wholesale brokerage business and therefore expect this average policy size to increase gradually over time.

No one customer accounts for 10% or more of our insurance segments in the aggregate.

Geographic Markets

We principally sell in the following geographic markets:


•	Standard Commercial Lines products and services are primarily sold in 22 states located in the Eastern and Midwestern regions of the United States and the District of Columbia. In 2017, we also plan on expanding into the Southwest region of the United States.


•	Standard Personal Lines products and services are primarily sold in 13 states located in the Eastern and Midwestern regions of the United States, except for the flood portion of this segment, which is sold in all 50 states and the District of Columbia.


•	E&S Lines are sold in all 50 states and the District of Columbia.

We believe this geographic diversification lessens our exposure to regulatory, competitive, and catastrophic risk. The following table lists the principal states in which we write business and the percentage of total NPW each represents for the last three fiscal years:



	Years ended December 31,
% of NPW	2016		2015	2014
New Jersey	20.2	%	21.2	22.6
Pennsylvania	11.8		11.7	11.4
New York	7.8		7.2	7.1
Maryland	5.4		5.4	5.6
Virginia	4.6		4.6	4.6
Georgia	4.3		4.1	3.8
Indiana	3.9		4.3	4.5
North Carolina	3.9		3.7	3.4
Illinois	3.6		3.7	4.0
Michigan	3.3		3.5	3.3
South Carolina	3.1		3.0	3.1
Massachusetts	2.9		2.8	2.7
Other states	25.2		24.8	23.9
Total	100.0	%	100.0	100.0

We support geographically diversified business from our corporate headquarters in Branchville, New Jersey, and our six regional branches (referred to as our “Regions”). The table below lists our Regions and where they have office locations:



Region		Office Location
Heartland		Carmel, Indiana
New Jersey		Hamilton, New Jersey
Northeast		Branchville, New Jersey
Mid-Atlantic		Allentown, Pennsylvania and Hunt Valley, Maryland
Southern		Charlotte, North Carolina
E&S		Horsham, Pennsylvania and Scottsdale, Arizona

We recently established a Southwest region in anticipation of expanding our geographic footprint for Standard Commercial Lines. We currently expect to start writing premium in Arizona in the latter half of 2017 and may consider opening up more states in the Southwest region. In addition, we also expect to start writing business in New Hampshire in the latter half of 2017. These new states leverage our current operating model, which is predicated around our field-based underwriting, franchise distribution model, and excellent customer service. Over time, we currently expect to expand into additional states.

Distribution Channel

We sell our insurance products and services through the following types of distribution partners:


•	Standard Commercial Lines: independent retail agents;


•	Standard Personal Lines: independent retail agents; and


•	E&S Lines: wholesale general agents and brokers.

We pay our distribution partners commissions that are based on a percentage of gross premiums written, and in some cases are further based on profit calculations, and other consideration for business placed with us. We seek to compensate them fairly and in a manner consistent with market practices. No one distribution partner is responsible for 10% or more of our combined insurance segments' premium.

As our customers rely heavily on our distribution partners, it is sometimes difficult to develop brand recognition as these customers cannot always differentiate between their insurance agents and their insurance carriers. We continue to evolve our service model, post policy-acquisition, with an increasing focus on the customer. Our goal is to provide our customers with 24/7 access to transactional capabilities and account information. Customers expect this level of access from every business and, while many insurers offer such solutions in the personal lines space, we want to be a leader in this area for the small commercial lines market. When combined with our digital strategy, we believe this level of access will significantly improve the customer experience. Within our digital strategy, we provide self-servicing capabilities via a mobile application and a web-

based portal where our customers have access to basic account information on demand. These efforts will allow us to continue to offer customers a shared experience with our distribution partners, while positioning us to more directly demonstrate our value proposition.

Independent Retail Agents

According to a study released in 2016 by the Independent Insurance Agents & Brokers of America, independent retail insurance agents and brokers write approximately 80% of standard commercial lines insurance and 35% of standard personal lines insurance in the United States. We believe that independent retail insurance agents will remain a significant force in overall insurance industry premium production because they represent more than one insurance carrier and therefore are able to provide a wider choice of commercial and personal lines insurance products and risk-based consultation to customers.

We currently have approximately 1,180 independent retail agents selling our Standard Commercial Lines business, 710 of which also sell our Standard Personal Lines business (excluding flood). In total, these 1,180 distribution partners have approximately 2,200 office locations selling our business. In addition, we have approximately 5,600 distribution partners selling our flood insurance products.

In a 2016 survey, we received an overall satisfaction score of 8.76 out of 10 from our standard market distribution partners, which, we believe, highlighted their satisfaction with our products, the ease of reporting claims, and the professionalism and effectiveness of our employees.

Wholesale General Agents

E&S Lines are written almost exclusively through approximately 80 wholesale general agents and brokers with 205 office locations, who are our distribution partners in the E&S market, although we recently expanded into the wholesale brokerage business. We have granted contract binding authority to these partners for business that meets our prescribed underwriting and pricing guidelines.

Marketing

Our primary marketing strategy is to:


•	Use an empowered field underwriting model to provide our Standard Commercial Lines retail distribution partners with resources within close geographic proximity to their businesses and our customers. For further discussion on this, see the “Field Model and Technology” section below.


•	Develop close relationships with each distribution partner, as well as their principals and producers: (i) by soliciting their feedback on products and services; (ii) by advising them concerning our product developments; and (iii) through education and development focusing on producer recruitment, sales training, enhancing customer experience, online marketing, and distribution operations.


•	Develop with each distribution partner, and then carefully monitor, annual goals regarding: (i) types and mix of risks placed with us; (ii) amount of premium or number of policies placed with us; (iii) customer service and retention levels; and (iv) profitability of business placed with us.


•	Develop brand recognition with our customers through our marketing efforts, which include radio and television advertising, as well as advertising at certain national and local sporting events.

Field Model and Technology

We use the service mark “High-tech x High-touch = HT^{2 SM}” to describe our business strategy. “High-tech” refers to our technology that we use to make it easy for our distribution partners and customers to do business with us. “High-touch” refers to the close relationships that we have with our distribution partners and customers through our field business model.

High Tech

We leverage the use of technology in our business. We have made significant investments in information technology platforms, integrated systems, internet-based applications, and predictive modeling initiatives. We do this to provide:


•	Our distribution partners and customers with access to accurate business information and the ability to process certain transactions from their locations, seamlessly integrating those transactions into our systems;


•	Our underwriters with targeted underwriting and pricing tools to enhance profitability while growing the business;


•	Our workers compensation claims adjusters with predictive tools to indicate when claims are likely to escalate;


•	Our Special Investigations Unit ("SIU") investigators access to our business intelligence systems to better identify claims with potential fraudulent activities;


•	Our claims recovery and subrogation departments with the ability to expand and enhance their models through the use of our business intelligence systems; and


•	Our customers with 24/7 access to transactional capabilities and information through a web-based customer portal and a customer mobile application.

In 2016, we received the following awards:


•	NetVu Automation Excellence Award, which recognizes carriers that make it easier for agencies to do business;


•	ACORD Leadership Award, which is presented to an organization or an individual demonstrating leadership in the areas of standards development, advocacy, and/or implementation. It recognizes carriers that are guiding the insurance industry towards greater clarity in the sharing of insurance data; and


•	IIBA Leadership Excellence in the Advancement of the Practice of Business Analysis, which is presented annually to a company that adapts, optimizes, and evolves business analysis best practices and standards by implementing effective tools, processes, and methodologies that enable better business capabilities.

We manage our information technology projects through an Enterprise Project Management Office (“EPMO”) governance model. The EPMO is supported by certified project managers who apply methodologies to: (i) communicate project management standards; (ii) provide project management training and tools; (iii) manage projects; (iv) review project status and cost; and (v) provide non-technology project management consulting services to the rest of the organization. The EPMO, which includes senior management representatives from all major business areas, corporate functions, and information technology, meets regularly to review all major initiatives and receives reports on the status of other projects. We believe the EPMO is an important factor in the success of our technology implementation.

Our primary technology operations are located in Branchville, New Jersey and Glastonbury, Connecticut. We have agreements with multiple consulting, information technology, and service providers for supplemental staffing services. Collectively, these providers supply approximately 54% of our skilled technology capacity and are principally based in the U.S., although we do contract with some service providers who are based, or utilize resources, outside the U.S. We retain management oversight of all projects and ongoing information technology production operations. We believe we would be able to manage an efficient transition to new vendors without significant impact to our operations if we terminated an existing vendor.

High Touch

To support our distribution partners, we employ a field model for both underwriting and claims, with various employees in the field, usually working from home offices near our distribution partners. We believe that we build better and stronger relationships with our distribution partners because of the close proximity of our field employees, and the resulting direct interaction with our distribution partners and customers. At December 31, 2016, we had approximately 2,250 employees, of which 310 worked in the field, 870 worked in one of our regional offices, and the remainder worked in our corporate office.

Underwriting Process

Our underwriting process requires communication and interaction among:


•	Our Regions, which establish and execute upon: (i) annual premium and pricing goals; (ii) specific new business targets by distribution partner; and (iii) profit improvement plans as needed across lines, states, and/or distribution partners;


•	Our corporate underwriting department, which develops our underwriting appetite, products, policy forms, pricing, and underwriting guidelines for our standard market and E&S market business;


•	Our corporate actuaries who assist in the determination of rate and pricing levels, while monitoring pricing and profitability along with the Regions, corporate underwriting department, and business intelligence staff for our standard market and with E&S market business;


•	Our distribution partners, which include independent retail agents for our standard market business and wholesale general agents for our E&S market business, that provide front-line underwriting within our prescribed guidelines;


•	Our Agency Management Specialists (“AMSs”), who: (i) manage the growth and profitability of business that their assigned distribution partners write with us; and (ii) perform field underwriting for new Standard Commercial Lines business;


•	Our territory managers who have oversight of the AMS production team, ensure that: (i) annual profit and growth plans are developed on a state by state basis; (ii) the achievement of these state plans are monitored at the state, AMS territory and account level; and (iii) individual agency plans are developed and monitored for achievement annually.


•	Our Standard Commercial Lines small business teams that are responsible for handling: (i) new business in need of review that was submitted by our distribution partners through our automated underwriting platform, One & Done^®; and (ii) other new small accounts and middle market accounts with low underwriting complexity;


•	Our Safety Management Specialists (“SMSs”), who provide a wide range of front-line safety management services to our Standard Commercial Lines customers as discussed more fully below;


•	Our regional underwriters, who manage the in force policies for their assigned distribution partners, including, but not limited to, managing profitability and pricing levels within their portfolios by developing policy-specific pricing;


•	Our premium auditors, who supplement the underwriting process by working with insureds to accurately audit exposures for certain policies that we write;


•	Our field technical coordinators, who are responsible for technology assistance and training to aid our employees and distribution partners;


•	Our Standard Personal Lines Marketing Specialists (“PLMSs”), who have primary responsibility for identifying new opportunities to grow our Standard Personal Lines; and


•	Our E&S territory managers, who have primary responsibility for identifying new opportunities to grow our E&S Lines.

We have an underwriting service center (“USC”) located in Richmond, Virginia. The USC assists our distribution partners by servicing certain Standard Personal Lines and smaller Standard Commercial Lines accounts. At the USC, many of our employees are licensed agents who respond to customer inquiries about insurance coverage, billing transactions, and other matters. For the convenience of using the USC and our handling of certain transactions, our distribution partners agree to receive a slightly lower than standard commission for the premium associated with the USC. As of December 31, 2016, our USC was servicing Standard Commercial Lines NPW of $51.8 million and Standard Personal Lines NPW of $28.5 million. The $80.3 million total serviced by the USC represents 4% of our total NPW.

As mentioned above, our field model provides a wide range of front-line safety management services focused on improving a Standard Commercial Lines insured’s safety and risk management programs. Our service mark “Safety Management: Solutions for a safer workplace”^SM includes: (i) risk evaluation and improvement surveys intended to evaluate potential exposures and provide solutions for mitigation; (ii) internet-based safety management educational resources, including a large library of coverage-specific safety materials, videos and online courses, such as defensive driving and employee educational safety courses; (iii) thermographic infrared surveys aimed at identifying electrical hazards; and (iv) Occupational Safety and Health Administration construction and general industry certification training. Risk improvement efforts for existing customers are designed to improve loss experience and policyholder retention through valuable ongoing consultative service. Our safety management goal is to work with our customers to identify, mitigate, and eliminate potential loss exposures.

Claims Management

Effective, fair, and timely claims management is one of the most important services that we provide to our customers and distribution partners. It is also one of the critical factors in achieving underwriting profitability. We have structured our claims organization to emphasize: (i) cost-effective delivery of claims services and control of losses and loss expenses; and (ii) maintenance of timely and adequate claims reserves. In connection with our Standard Commercial Lines and Standard Personal Lines, we achieve better claim outcomes through a field model that locates claim representatives in close proximity to our customers and distribution partners.

We have a claims service center (“CSC”), co-located with the USC, in Richmond, Virginia. The CSC receives first notices of loss from our customers and claimants related to our Standard Commercial Lines and Standard Personal Lines and manages routine automobile and property claims with no injuries. The CSC is designed to help: (i) reduce the claims settlement time on first- and third-party automobile property damage claims; (ii) increase the use of body shops, glass repair shops, and car rental agencies that have contracted with us at discounted rates and specified service levels; (iii) handle and settle small property claims; and (iv) investigate and negotiate auto liability claims. The CSC, as appropriate, will assign claims to the appropriate regional claims office or other specialized area within our claims organization.

Claims Management Specialists (“CMSs”) are responsible for investigating and resolving the majority of our standard marketplace commercial automobile bodily injury, general liability, and property losses with low severities. We also have Property Claims Specialists ("PCSs") to handle property claims with severities ranging from $5,000 to $100,000. Strategically located throughout our footprint, CMSs and PCSs are able to provide highly responsive customer and distribution partner service to quickly resolve claims within their authority.

Our E&S claims processing is consistent with our Standard Commercial Lines and Standard Personal Lines claims processing. E&S claims are handled in our standard lines regional offices and are segregated by line of business (property and liability), litigation, and complexity. Our Quality Assurance Unit conducts monthly file reviews on all of our operations to validate compliance with our quality claim handling standards. Complex claims oversight is handled by the Complex Claims Unit ("CCU").

We have implemented specialized claims handling as follows:


•	Liability claims with high severity or technically complex losses are handled by the CCU. The CCU specialists are primarily field based and handle losses based on injury type or with severities greater than $250,000.


•	Litigated matters not meeting the CCU criteria are handled within our regional offices by our litigation claim units. These teams are aligned based upon jurisdictional knowledge and technical experience. In addition, they are supervised by litigation managers within the regional claim offices. These claims are segregated from the CMSs to allow for focused management.


•	Workers compensation claims handling is centralized in Charlotte, North Carolina. Jurisdictionally trained and aligned medical only and lost-time adjusters manage non-complex workers compensation claims within our footprint. Claims with high exposure and/or significant escalation risk are referred to the workers compensation strategic case management unit.


•	Low severity/high volume property claims are handled by the CSC. Certain complex claims that do not involve structural damage (i.e. employee dishonesty and equipment breakdown losses) are handled by a small group of specialists in the CSC.


•	The Large Loss Unit ("LLU") handles complex property claims, typically those in excess of $100,000.


•	All asbestos and environmental claims are referred to our specialized corporate Environmental Unit, which also handles latent claims.

This structure allows us to provide experienced adjusting to each claim category.

All insurance segments are supported by the SIU that investigates potential insurance fraud and abuse, and supports efforts by regulatory bodies and trade associations to curtail the cost of fraud. We have developed a proprietary SIU fraud detection model that identifies the potential fraud cases early on in the life of the claim. The SIU adheres to uniform internal procedures to improve detection and take action on potentially fraudulent claims. It is our practice to notify the proper authorities of SIU findings, which we believe sends a clear message that we will not tolerate fraud against us or our customers. The SIU supervises anti-fraud training for all claims adjusters and AMSs.

Insurance Operations Competition

Our insurance segments face competition from public, private, and mutual insurance companies, which may have lower operating costs and/or lower cost of capital than we do. Some, like us, rely on partners for the distribution of their products and services and have competition within their distribution channel, making growth in market share difficult. Other insurance carriers either employ their own agents who only represent them or use a combination of distribution partners, captive agents, and direct marketing. The following provides information on the competition facing our insurance segments:

Standard Commercial Lines

The Standard Commercial Lines property and casualty insurance market is highly competitive and market share is fragmented among many companies. We compete with two types of companies, primarily on the basis of price, coverage terms, claims service, customer experience, safety management services, ease of technology usage, and financial ratings:


•	Regional insurers, such as Cincinnati Financial Corporation, Erie Indemnity Company, The Hanover Insurance Group, Inc., and United Fire Group, Inc.; and


•	National insurers, such as The Hartford Financial Services Group, Inc., Liberty Mutual Holding Company Inc., Nationwide Mutual Insurance Company, The Travelers Companies, Inc., and Zurich Insurance Group, Ltd.

Standard Personal Lines

Our Standard Personal Lines face competition primarily from the regional and national carriers noted above, as well as companies such as State Farm Mutual Automobile Insurance Company and Allstate Corporation. In addition, we face competition from direct insurers such as The Government Employees Insurance Company and The Progressive Corporation, which primarily offer personal auto coverage and market through a direct-to-consumer model.

E&S Lines

Our E&S Lines face competition from the E&S subsidiaries of the regional and national carriers named above, as well as the following companies:


•	Nautilus Insurance Group, a member of W. R. Berkley Company;


•	Colony Specialty, a member of the Argo Group International Holding Ltd;


•	Western World Insurance Group, a member of the Validus Group;


•	Century Insurance Group, a member of the Meadowbrook Insurance Group;


•	The Burlington Insurance Company, a member of IFG Companies;


•	United States Liability Insurance Group, a member of Berkshire Hathaway, Inc.;


•	Scottsdale Insurance Company, a member of Nationwide Mutual Insurance Company; and


•	Markel Corporation.

Other

In addition, both existing competitors and new industry participants are developing new platforms that are leveraging technology and the Internet to provide a low cost "direct to the customer" model. New competitors emerging under this digital platform include, but are not limited to, Lemonade, Attune, and Metromile. Many of these new entrants have significant financial backing. Further, reinsurers have entered certain primary property and casualty insurance markets to diversity their operations and compete with us.

Insurance Regulation

Primary Oversight by the States in Which We Operate

Our insurance segments are heavily regulated. The primary public policy behind insurance regulation is the protection of policyholders and claimants over all other constituencies, including shareholders. By virtue of the McCarran-Ferguson Act, Congress has largely delegated insurance regulation to the various states. The primary market conduct and financial regulators of our Insurance Subsidiaries are the departments of insurance in the states in which they are organized and are licensed. For a discussion of the broad regulatory, administrative, and supervisory powers of the various departments of insurance, refer to the risk factor that discusses regulation in Item 1A. “Risk Factors.” of this Form 10-K.

Our various state insurance regulators are members of the NAIC. The NAIC has codified SAP and other accounting reporting formats and drafts model insurance laws and regulations governing insurance companies. An NAIC model only becomes law when it is enacted in the various state legislatures or promulgated as a regulation by the state insurance department. The adoption of certain NAIC model laws and regulations, however, is a key aspect of the NAIC Financial Regulations Standards and Accreditation Program.

NAIC Monitoring Tools

Among the NAIC's various financial monitoring tools that are material to the regulators in states in which our Insurance Subsidiaries are organized are the following:

•

The Insurance Regulatory Information System (“IRIS”). IRIS identifies 13 industry financial ratios and specifies “usual values” for each ratio. Departure from the usual values on four or more of the financial ratios can lead to inquiries from individual state insurance departments about certain aspects of the insurer's business. Our Insurance Subsidiaries have consistently met the majority of the IRIS ratio tests.

•

Risk-Based Capital. Risk-based capital is measured by four major areas of risk to which property and casualty insurers are exposed: (i) asset risk; (ii) credit risk; (iii) underwriting risk; and (iv) off-balance sheet risk. Insurers face a steadily increasing amount of regulatory scrutiny and potential intervention as their total adjusted capital declines below two times their "Authorized Control Level". Based on our 2016 statutory financial statements, which have been prepared in accordance with SAP, the total adjusted capital for each of our Insurance Subsidiaries substantially exceeded two times their Authorized Control Level.

•

Annual Financial Reporting Regulation (referred to as the "Model Audit Rule"). The Model Audit Rule, which is modeled closely on the Sarbanes-Oxley Act of 2002, as amended ("Sarbanes-Oxley Act"), regulates: (i) auditor independence; (ii) corporate governance; and (iii) internal control over financial reporting. As permitted under the Model Audit Rule, the Audit Committee of the Board of Directors (the “Board”) of the Parent also serves as the audit committee of each of our Insurance Subsidiaries.

•

Own Risk and Solvency Assessment ("ORSA"). ORSA requires insurers to maintain a framework for identifying, assessing, monitoring, managing, and reporting on the “material and relevant risks” associated with the insurers' (or insurance groups') current and future business plans. ORSA, which has been adopted by the state insurance regulators of our Insurance Subsidiaries, requires companies to file an internal assessment of their solvency with insurance regulators annually. Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such standard will be developed over time and may increase insurers' minimum capital requirements, which could adversely impact our growth and return on equity.

In addition to the formal regulation above, we are subject to capital adequacy monitoring by rating agencies, for example, Best's Capital Adequacy Ratio ("BCAR"). BCAR, which was developed by A.M. Best, examines an insurer's leverage, underwriting activities, and financial performance.

Federal Regulation

Notable federal legislation and administrative policies that affect the insurance industry are:


•	The Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA");


•	The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”); and


•	Various privacy laws that apply to us because we have personal non-public information, including the:


◦	Gramm-Leach-Bliley Act;


◦	Fair Credit Reporting Act;


◦	Drivers Privacy Protection Act; and


◦	Health Insurance Portability and Accountability Act.

Like all businesses, we are required to enforce the economic and trade sanctions of the Office of Foreign Assets Control (“OFAC”).

FEMA oversees the WYO Program enacted by Congress. Congress sets the WYO Program's budgeting, rules, and rating parameters. Two significant pieces of legislation that impact the WYO Program are the Biggert-Waters Flood Insurance Reform Act of 2012 ("Bigger-Waters Act") and the Homeowner Flood Insurance Affordability Act of 2014 ("Flood Affordability Act"). The Biggert-Waters Act: (i) extended the NFIP funding to September 30, 2017; and (ii) moved the program to more market based rates for certain flood policies. The Flood Affordability Act repealed and modified certain provisions in the Biggert-Waters Act regarding premium adjustments. The NFIP authorization expires on September 30, 2017. Congress has been considering options to the NFIP and it is expected that the program will be extended.

In response to the financial markets crises in 2008 and 2009, the Dodd-Frank Act was enacted in 2010. This law provided for, among other things, the following:


•	The establishment of the Federal Insurance Office (“FIO”) under the United States Department of the Treasury;


•	Federal Reserve oversight of financial services firms designated as systemically important; and


•	Corporate governance reforms for publicly traded companies.

The FIO, the Federal Reserve, state regulators, and other regulatory bodies have been developing models for capital standards, negotiating a covered agreement on reinsurance collateral, and have been gathering data as required under the Dodd-Frank Act. Changes to the Dodd-Frank Act and FIO are expected in 2017 as the Trump Administration and the Republican Congress seek opportunities to pare down the Dodd-Frank Act and its regulations. For additional information on the potential impact of the Dodd-Frank Act, refer to the risk factor related to this legislation within Item 1A. “Risk Factors.” of this Form 10-K.

International Regulation

We believe that development of global capital standards will influence the development of similar standards by domestic regulators. Notable international developments include the following:


•	In 2014, the International Association of Insurance Supervisors proposed Basic Capital Standards for Global Systemically Important Insurers as well as a uniform capital framework for internationally active insurers; and


•	The European Union enacted Solvency II, which sets out new requirements on capital adequacy and risk management for insurers operating in Europe, which was implemented in 2016.

For additional information on the potential impact of international regulation on our business, refer to the risk factor related to regulation within Item 1A. “Risk Factors.” of this Form 10-K.

Investment Segment

Our Investment segment invests insurance premiums, as well as amounts generated through our capital management strategies, which may include the issuance of debt and equity securities, to generate investment income and to satisfy obligations to our customers, our shareholders, and our debt holders, among others. At December 31, 2016, our investment portfolio consisted of the following:



Category of Investment
($ in millions, except invested assets per dollar of stockholders' equity)	Carrying Value		% of Investment Portfolio
Fixed income securities	$	4,894.1	92
Equity securities	146.7		2
Short-term investments	221.7		4
Other investments, including alternatives	102.4		2
Total	$	5,364.9	100
Invested assets per dollar of stockholders' equity	$	3.50

Our investment philosophy includes certain return and risk objectives for the fixed income, equity, and other investment portfolios. After-tax yield and income generation are key drivers to our investment strategy, which has historically been balanced with a long-term “buy-and-hold,” low turnover approach.

During 2016, we determined that a more active management approach to our investment portfolio was appropriate to maximize the risk-adjusted after-tax income and total return of the portfolio, while maintaining a similar level of credit quality and duration risk. We evaluated our previous buy-and-hold low turnover approach in the context of the current market environment, and concluded that a change was appropriate to more effectively diversify, navigate, and manage the portfolio in response to a persistently low and volatile interest rate environment, the potential for rising inflation, and an uncertain political and tax landscape.

To execute on this revised approach, we hired several new investment managers who were on-boarded in the fourth quarter of 2016. We modestly increased our exposure to below investment grade fixed income securities, private equity, and private credit strategies to further diversify our allocation within risk assets, which principally includes public equities, high-yield fixed income securities, and private equity, in conjunction with repositioning the portfolio to a long-term target risk asset allocation of approximately 10% of total invested assets. While our approach to managing the investment portfolio has changed, our core investment philosophy has not changed. We remain focused on diversification, capital preservation, investment quality, and liquidity to meet our needs and obligations.

For further information regarding our risks associated with the overall investment portfolio, see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk.” and Item 1A. “Risk Factors.” of this Form 10-K. For additional information about investments, see the section entitled, “Investments,” in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” and Item 8. “Financial Statements and Supplementary Data.” Note 5. of this Form 10-K.

Reports to Security Holders

We file with the SEC all required disclosures, including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, Proxy Statements, and other required information under Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (“Exchange Act”). We provide access to these filed materials on our Internet website, www.Selective.com.

Item 1A. Risk Factors.

Any of the following risk factors could cause our actual results to differ materially from historical or anticipated results. They could have a significant impact on our business, liquidity, capital resources, results of operations, financial condition, and debt ratings. These risk factors might affect, alter, or change actions that we might take in executing our long-term capital strategy, including, but not limited to, contributing capital to any or all of the Insurance Subsidiaries, issuing additional debt and/or equity securities, repurchasing our equity securities, redeeming our fixed income securities, or increasing or decreasing stockholders’ dividends. This list of risk factors is not exhaustive, and others may exist.

In an effort to highlight recent trends that may impact our business, we have identified risk factors impacted by: (i) potential changes to the U.S. federal tax code; (ii) other impacts of the Presidential election and Republican Congress; and (iii) other evolving legislation. Following these sections are the ongoing risks that continue to impact our business segments, as well as our corporate structure and governance.

U.S. Federal Tax Code

Changes in tax legislation initiatives could adversely affect our results of operations and financial condition.

We are subject to the tax laws and regulations of U.S. federal, state, and local governments, which may be amended in ways that adversely impact us. Recently, there has been significant debate about reform of the current U.S. federal tax code. Although some reform proposals may be beneficial to the insurance industry overall, we cannot predict what impact any enacted reform proposals could have on our results of operations, liquidity, financial condition, financial strength, and debt ratings. For example, if the existing U.S. federal corporate income tax rate is reduced from its current 35%, any deferred tax assets would be reduced and we would likely be required to recognize a reduction of a previously-recognized federal tax benefit in the period when enacted. This and other potential tax rule changes may increase or decrease our actual tax expense and could materially and adversely affect our results of operations. If the corporate tax rate is reduced to between 15% and 20%, we would be required to record a non-cash write off of deferred tax assets to income of approximately $36 million to $49 million.

Recent tax reform proposals have included border adjustment provisions that could tax imports of products and services from foreign states. Some proposals call for significant tariffs. We have agreements for products and services with foreign domiciled companies, such as information technology services. In addition, risk transfer may or may not be included in the definition of products and services; therefore, our reinsurance treaties, many of which are with non-U.S. reinsurance companies, may be impacted by any new proposals. If new taxes are imposed on these products and services, it is possible that our expenses for these items could increase, perhaps significantly. We cannot predict the impact such proposals could have on our products and services supplier relationships, results of operations, liquidity, financial condition, financial strength, and debt ratings if enacted.

Changes in tax legislation initiatives could adversely affect our investments results.

Amendments to the tax laws and regulations of U.S. federal, state, and local governments may adversely impact us. Our investment portfolio has benefited from tax exemptions and certain other tax laws, including, but not limited to, those governing dividends received deductions and tax-advantaged municipal bond interest. Future federal and/or state tax legislation could be enacted to lessen or eliminate some or all of these favorable tax advantages. This could negatively impact the value of our investment portfolio and, in turn, materially and adversely impact our results of operations.

If the recent renewed debate about revamping the current U.S. federal tax code results in enacted changes, it is possible that some changes may be beneficial to the insurance industry overall. We, however, cannot predict what impact such enacted proposals could have on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

If we experience difficulties with outsourcing relationships, our ability to conduct our business might be negatively impacted.

We outsource certain business and administrative functions to third parties for efficiencies and cost savings, and may do so increasingly in the future. If we fail to develop and implement our outsourcing strategies or our third-party providers fail to perform as anticipated, we may experience operational difficulties, increased costs, and a loss of business that may have a material adverse effect on our results of operations or financial condition. Currently, we have agreements with multiple consulting, information technology, and service providers for supplemental staffing services. Collectively, these providers supply approximately 54% of our skilled technology capacity and are principally based in the U.S., although we do contract with some service providers who are based, or utilize resources, outside of the U.S. As mentioned above, the availability and cost of these services may be impacted by potential tax reform proposals.

Other Potential Impacts of the Presidential Election and the Republican Majority Congress

We are subject to the risk that legislation will be passed that significantly changes insurance regulation and adversely impacts our business, financial condition, and/or the results of operations.

In 2009, the Dodd-Frank Act was enacted to address corporate governance and control issues identified in the financial markets crises in 2008 and 2009 and issues identified in the operations of non-insurance subsidiaries of American International Group, Inc. The Dodd-Frank Act created the FIO as part of the U.S. Department of Treasury to advise the federal government on insurance issues. The Dodd-Frank Act also requires the Federal Reserve, through the Financial Services Oversight Council (“FSOC”), to supervise financial services firms designated as systemically important financial institutions ("SIFI"). The FSOC has not designated us as a SIFI. The Dodd-Frank Act also included a number of corporate governance reforms for publicly traded companies, including proxy access, say-on-pay, and other compensation and governance issues. Critics of the Dodd-Frank Act are proposing various reforms to the act, and it is possible that some provisions of the law may be modified to lessen regulatory burdens.

In general, the Trump Administration and the Republican Majority in Congress favor less federal involvement in insurance. It is possible, however, that there may be legislative proposals in Congress that could result in the federal government directly regulating the business of insurance. President Trump and the Republican Majority in Congress favor the repeal of the Affordable Care Act ("ACA"). Repeal of the law raises some legal and practical challenges. Some reform proposals include a provision to permit sales of insurance across state lines, which under current federal law cannot be sold across state lines without the approval of the respective state insurance regulators. As part of some ACA reform proposals, there are calls for the elimination of the anti-trust exemptions for health insurers under the McCarran-Ferguson Act. While we are not a health insurer, we and the property and casualty industry operate under anti-trust exemptions that permit the aggregation of claims and other data necessary under the law of large numbers to price insurance. If similar proposals related to the property and casualty industry were made and enacted, we would have to seek a business practices exemption from the Department of Justice to share information with other insurers. We cannot predict the impact such proposals, if enacted, could have on our product and services supplier relationships, results of operations, liquidity, financial condition, financial strength, and debt ratings.

There also are legislative and regulatory proposals in various states that seek to limit the ability of insurers to assess insurance risk. From time-to-time, proposals in various states seek to limit the ability of insurers to use certain factors or predictive measures in the underwriting of property and casualty risks. Among the proposed legislation and regulation have been limits on the use of insurance scores and marketplace considerations. These proposals, if enacted, could impact underwriting pricing and results.

We cannot predict what federal and state rules or legislation will be proposed and adopted, or what impact, if any, such proposals or the cost of compliance with such proposals, could have on our results of operations, liquidity, financial condition, financial strength, and debt ratings if enacted.

Deterioration in the public debt and equity markets, the private investment marketplace, uncertainty regarding political developments and the economy could lead to investment losses, which may adversely affect our results of operations, financial condition, liquidity, and debt ratings.

Like most property and casualty insurance companies, we depend on income from our investment portfolio for a significant portion of our revenue and earnings. Our investment portfolio is exposed to significant financial and capital market risks, both in the U.S. and abroad, and volatile changes in general market or economic conditions could lead to a decline in the market value of our portfolio as well as the performance of the underlying collateral of our structured securities. Concerns over weak economic growth globally, elevated unemployment, volatile energy and commodity prices, and geopolitical issues, among other factors, contribute to increased volatility in the financial markets, increased potential for credit downgrades, and decreased liquidity in certain investment segments. In addition, President Donald J. Trump has proposed significant changes in United

States domestic and foreign policy. The uncertainty regarding these proposed changes, and whether they will be implemented, may elevate the volatility of the financial markets and adversely impact our investment portfolio.

Our notes payable and line of credit are subject to certain debt-to-capitalization restrictions and net worth covenants, which could be impacted by a significant decline in investment value. Further OTTI charges could be necessary if there is a significant future decline in investment values. Depending on market conditions going forward, and in the event of extreme prolonged market events, such as the global credit crisis, we could incur additional realized and unrealized losses in future periods, which could have an adverse impact on our results of operations, financial condition, debt and financial strength ratings, and our ability to access capital markets as a result of realized losses, impairments, and changes in unrealized positions.

Other Evolving Legislation

We face risks regarding our flood business because of uncertainties regarding the NFIP.

We are the sixth largest insurance group participating in the WYO arrangement of the NFIP, which is managed by the Mitigation Division of the Federal Emergency Management Agency (“FEMA”) in the U.S. Department of Homeland Security. For WYO participation, we receive an expense allowance for policies written and a servicing fee for claims administered. Under the program, all losses are 100% reinsured by the Federal Government. Currently, the expense allowance is 30.9% of DPW. The servicing fee is the combination of 0.9% of DPW and 1.5% of incurred losses.

As a WYO carrier, we are required to follow certain NFIP procedures when administering flood policies and claims. Some of these requirements may differ from our normal business practices and may present a reputational risk to our brand. Insurance companies are regulated by states and the NFIP requires WYO carriers to be licensed in the states in which they operate. The NFIP, however, is a federal program and WYO carriers are fiscal agents of the U.S. Government and must follow the directives of the NFIP. Consequently, we have the risk that directives of the NFIP and a state regulator on the same issue may conflict.

There has been significant public policy and political debate regarding the NFIP and its outstanding debt, including the obtainment of reinsurance coverage for NFIP losses. In 2016, FEMA secured its first placement of reinsurance for the NFIP. In January 2017, FEMA expanded its September 2016 placement and transferred $1 billion of the NFIP's financial risk to reinsurers through January 1, 2018. In addition, there are several legislative proposals in Congress regarding NFIP reauthorization. The NFIP statute will expire on September 30, 2017, unless reauthorized by Congress. While it is possible that the NFIP program will be reauthorized with limited changes to the underlying structure, there is substantial uncertainty about the future of the program given the changing political environment. Our flood business could be impacted by: (i) any mandate for primary insurance carriers to provide flood insurance; or (ii) private writers becoming more prevalent in the marketplace. The uncertainty created by the public policy debate and politics of flood insurance reform make it difficult for us to predict the future of the NFIP and our continued participation in the program.

We are subject to attempted cyber-attacks and other cybersecurity risks.

Our business heavily relies on various information technology and application systems that are connected to, or may be accessed from, the Internet and may be impacted by a malicious cyber-attack. Our systems also contain confidential and proprietary information regarding our operations, our employees, our agents, and our customers and their employees and property, including personally identifiable information. We have developed and invested, and expect to continue to do both, in a variety of controls to prevent, detect, and appropriately react to such cyber-attacks, including frequently testing our systems' security and access controls. Cyber-attacks continue to become more complex and broad ranging and our internal controls provide only a reasonable, not absolute, assurance that we will be able to protect ourselves from significant cyber-attack incidents. By outsourcing certain business and administrative functions to third parties, we may be exposed to enhanced risk of data security breaches. Any breach of data security could damage our reputation and/or result in monetary damages, which, in turn, could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings. Although we have not experienced a material cyber-attack, it is possible that might occur. We have insurance coverage for certain cybersecurity risks, including privacy breach incidents, that provides protection up to $20 million above a deductible of $250,000.

Given the increased number of identity thefts from cyber-attacks, federal and state policymakers have proposed, and will likely continue to propose, increased regulation of the protection of personally identifiable information and the steps to be followed after a related cybersecurity breach. Compliance with these regulations and efforts to address continuingly developing cybersecurity risks may result in a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Risks Related to our Insurance Segments

Our loss and loss expense reserves may not be adequate to cover actual losses and expenses.

We are required to maintain loss and loss expense reserves for our estimated liability for losses and loss expenses associated with reported and unreported insurance claims. Our estimates of reserve amounts are based on facts and circumstances that we know, including our expectations of the ultimate settlement and claim administration expenses, including inflationary trends particularly regarding medical costs, predictions of future events, trends in claims severity and frequency, and other subjective factors relating to our insurance policies in force. There is no method for precisely estimating the ultimate liability for settlement of claims. We cannot be certain that the reserves we establish are adequate or will be adequate in the future. From time-to-time, we increase reserves if they are inadequate or reduce them if they are redundant. An increase in reserves: (i) reduces net income and stockholders’ equity for the period in which the reserves are increased; and (ii) could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

We are subject to losses from catastrophic events.

Our results are subject to losses from natural and man-made catastrophes, including, but not limited to: hurricanes, tornadoes, windstorms, earthquakes, hail, terrorism, explosions, severe winter weather, floods, and fires, some of which may be related to climate changes. The frequency and severity of these catastrophes are inherently unpredictable. One year may be relatively free of such events while another may have multiple events. For further discussion regarding man-made catastrophes that relate to terrorism, see the risk factor directly below regarding the potential for significant losses from acts of terrorism.

There is widespread interest among scientists, legislators, regulators, and the public regarding the effect that greenhouse gas emissions may have on our environment, including climate change. If greenhouse gasses continue to impact our climate, it is possible that more devastating catastrophic events could occur.

The magnitude of catastrophe losses is determined by the severity of the event and the total amount of insured exposures in the area affected by the event as determined by ISO's Property Claim Services unit. Most of the risks underwritten by our insurance segments are concentrated geographically in the Eastern and Midwestern regions of the country. In 2016, approximately 20% of NPW were related to insurance policies written in New Jersey. Catastrophes in the Eastern and Midwestern regions of the United States could adversely impact our financial results, as was the case in 2010, 2011, and 2012.

Although catastrophes can cause losses in a variety of property and casualty insurance lines, most of our historical catastrophe-related claims have been from commercial property and homeowners coverages. In an effort to limit our exposure to catastrophe losses, we purchase catastrophe reinsurance. Catastrophe reinsurance could prove inadequate if: (i) the various modeling software programs that we use to analyze the Insurance Subsidiaries’ risk result in an inadequate purchase of reinsurance by us; (ii) a major catastrophe loss exceeds the reinsurance limit or the reinsurers’ financial capacity; or (iii) the frequency of catastrophe losses results in our Insurance Subsidiaries exceeding the aggregate limits provided by the catastrophe reinsurance treaty. Even after considering our reinsurance protection, our exposure to catastrophe risks could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

We are subject to potentially significant losses from acts of terrorism.

As a Standard Commercial Lines and E&S Lines writer, we are required to participate in TRIPRA, which was extended by Congress to December 31, 2020. TRIPRA requires private insurers and the United States government to share the risk of loss on future acts of terrorism certified by the U.S. Secretary of the Treasury. Under TRIPRA, insureds with non-workers compensation commercial policies have the option to accept or decline our terrorism coverage or negotiate with us for other terms. In 2016, 89% of our Standard Commercial Lines non-workers compensation policyholders purchased terrorism coverage that included nuclear, biological, chemical, and radioactive ("NBCR") events. Terrorism coverage is mandatory for all primary workers compensation policies, so the TRIPRA back-stop applies to these policies. A risk exists that, if the U.S. Secretary of Treasury does not certify certain future terrorist events, we would be required to pay related covered losses without TRIPRA's risk sharing benefits. Examples of this potential risk are the 2013 Boston Marathon bombing and the 2015 shootings in San Bernardino, California, neither of which were certified as terrorism events.

Under TRIPRA, each participating insurer is responsible for paying a deductible of specified losses before federal assistance is available. This deductible is based on a percentage of the prior year’s applicable Standard Commercial Lines and E&S Lines

premiums. In 2017, our deductible is approximately $304 million. For losses above the deductible, the federal government will pay 83% of losses to an industry limit of $100 billion, and the insurer retains 17%. The federal share of losses will be reduced by 1% each year to 80% by 2020. Although TRIPRA’s provisions will mitigate our loss exposure to a large-scale terrorist attack, our deductible is substantial and could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

TRIPRA rescinded all previously approved coverage exclusions for terrorism. Many of the states in which we write commercial property insurance mandate that we cover fire following an act of terrorism regardless of whether the insured specifically purchased terrorism coverage. Likewise, terrorism coverage cannot be excluded from workers compensation policies in any state in which we write.

Personal lines of business have never been covered under TRIPRA. Homeowners policies within our Standard Personal Lines exclude nuclear losses, but do not exclude biological or chemical losses.

Our ability to reduce our risk exposure depends on the availability and cost of reinsurance.

We transfer a portion of our underwriting risk exposure to reinsurance companies. Through our reinsurance arrangements, a specified portion of our losses and loss expenses are assumed by the reinsurer in exchange for a specified portion of premiums. The availability, amount, and cost of reinsurance depend on market conditions, which may vary significantly. Most of our reinsurance contracts renew annually and may be impacted by the market conditions at the time of the renewal that are unrelated to our specific book of business or experience. Any decrease in the amount of our reinsurance will increase our risk of loss. Any increase in the cost of reinsurance that cannot be included in renewal price increases will reduce our earnings. Accordingly, we may be forced to incur additional expenses for reinsurance or may not be able to obtain sufficient reinsurance on acceptable terms. Either could adversely affect our ability to write future business or result in the assumption of more risk with respect to those policies we issue.

We are exposed to credit risk.

We are exposed to credit risk in several areas of our insurance segments, including from:

•

Our reinsurers, who are obligated to us under our reinsurance agreements. Amounts recoverable from our reinsurers can increase quickly and significantly during periods of high catastrophe loss activity, such as in the fourth quarter of 2012 due to losses incurred from Superstorm Sandy, and thus our credit risk to our reinsurers can increase significantly and will fluctuate over time. The relatively small size of the reinsurance market and our objective to maintain an average weighted rating of “A” by A.M. Best on our current reinsurance programs constrains our ability to diversify this credit risk. However, some of our reinsurance credit risk is collateralized.


•	Certain life insurance companies that are obligated to our customers, as we have purchased annuities from them under structured settlement agreements.


•	Some of our distribution partners, who collect premiums from our customers and are required to remit the collected premium to us.


•	Some of our customers, who are responsible for payment of premiums and/or deductibles directly to us.


•	The invested assets in our defined benefit plan, which partially serve to fund our liability associated with this plan. To the extent that credit risk adversely impacts the valuation and performance of the invested assets within our defined benefit plan, the funded status of the defined benefit plan could be adversely impacted and, as result, could increase the cost of the plan to us.

Our exposure to credit risk could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Difficult conditions in global capital markets and the economy may adversely affect our revenue and profitability and harm our business, and these conditions may not improve in the near future.

General economic conditions in the United States and throughout the world and volatility in financial and insurance markets may materially affect our results of operations. Factors such as business and consumer confidence, unemployment levels, consumer spending, business investment, government spending, the volatility and strength of the capital markets, and inflation all affect the business and economic environment and, indirectly, the amount and profitability of our business. During 2016, 34% of DPW in our Standard Commercial Lines business were based on payroll/sales of our underlying customers. An

economic downturn in which our customers decline in revenue or employee count can adversely affect our audit and endorsement premium in our Standard Commercial Lines.

Unfavorable economic developments could adversely affect our earnings if our customers have less need for insurance coverage, cancel existing insurance policies, modify coverage, or choose not to renew with us. Challenging economic conditions may impair the ability of our customers to pay premiums as they come due. Adverse economic conditions may have a material effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

A downgrade or a potential downgrade in our financial strength or credit ratings could result in a loss of business and could have a material adverse effect on our financial condition and results of operations.

A significant financial strength rating downgrade, particularly from A.M. Best, would affect our ability to write new or renewal business with customers, some of whom are required under various third party agreements to maintain insurance with a carrier that maintains a specified minimum rating. In addition, our $30 million line of credit ("Line of Credit") requires our Insurance Subsidiaries to maintain an A.M. Best rating of at least “A-” (one level below our current rating) and a default could lead to acceleration of any outstanding principal. Such an event could trigger default provisions under certain of our other debt instruments and negatively impact our ability to borrow in the future. As a result, any significant downgrade in our financial strength ratings could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings. Refer to Item 1. "Business" for our current financial strength ratings.

Nationally recognized statistical rating organizations ("NRSROs") also rate our long-term debt creditworthiness. Credit ratings indicate the ability of debt issuers to meet debt obligations in a timely manner and are important factors in our overall funding profile and ability to access certain types of liquidity. Our current senior credit ratings are as follows:



NRSRO	Credit Rating	Long Term Credit Outlook
A.M. Best	bbb+	Stable
S&P	BBB	Stable
Moody’s	Baa2	Stable
Fitch	BBB+	Stable

Downgrades in our credit ratings could have a material adverse effect on our financial condition and results of operations in many ways, including making it more expensive for us to access capital markets. We cannot predict possible actions NRSROs may take regarding our ratings that could adversely affect our business or the possible actions we may take in response to any such actions.

We have many competitors and potential competitors.

Demand for insurance is influenced by prevailing general economic conditions. The supply of insurance is related to prevailing prices, the levels of insured losses and the levels of industry capital which, in turn, may fluctuate in response to changes in rates of return on investments being earned in the insurance industry. In addition, pricing is influenced by the operating performance of insurers, as increased pricing may be necessary to meet return on equity objectives. As a result, the insurance industry historically has had cycles characterized by periods of intense price competition due to excessive underwriting capacity and periods when shortages of capacity and poor insurer operating performance drove favorable premium levels. If competitors price business below technical levels, we might reduce our profit margin to retain our best business.

Pricing and loss trends impact our profitability. For example, assuming retention and all other factors remain constant:


•	A pure price decline of approximately 1% would increase our statutory combined ratio by approximately 0.75 points;


•	A 3% increase in our expected claim costs for the year would cause our loss and loss expense ratio to increase by approximately 1.75 points; and


•	A combination of the two could raise the combined ratio by approximately 2.5 points.

We compete with regional, national, and direct-writer property and casualty insurance companies for customers, distribution partners, and employees. Some competitors are public companies and some are mutual companies. Many competitors are larger and may have lower operating costs and/or lower cost of capital. They may have the ability to absorb greater risk while maintaining their financial strength ratings. Consequently, some competitors may be able to price their products more competitively. These competitive pressures could result in increased pricing pressures on a number of our products and services, particularly as competitors seek to win market share, and may impair our ability to maintain or increase our profitability. Because of its relatively low cost of entry, the Internet has emerged as a significant place of new competition, both from existing competitors and new competitors. New competitors emerging under this digital platform include, but are not limited to, Lemonade, Attune, and Coverwallet. Additionally, reinsurers have entered certain primary property casualty insurance markets to diversify their operations and compete with us. Further new competition could cause changes in the supply or demand for insurance and adversely affect our business.

We have less loss experience data than our larger competitors.

We believe that insurers are competing and will continue to compete on their ability to use reliable data about their customers and loss experience in complex analytics and predictive models to assess the profitability of risks, as well as the potential for adverse claim development, recovery opportunities, fraudulent activities, and customer buying habits. With the consistent expansion of computing power and the decline in its cost, we believe that data and analytics use will continue to increase and become more complex and accurate. As a regional insurance group, the loss experience from our insurance operations is not large enough in all circumstances to analyze and project our future costs. In addition, we have more limited experience data related to our E&S business, which we purchased in 2011. We use data from ISO, AAIS, and NCCI to obtain industry loss experience to supplement our own data. While statistically relevant, that data is not specific to the performance of risks we have underwritten. Larger competitors, particularly national carriers, have a significantly larger volume of data regarding the performance of risks that they have underwritten. The analytics of their loss experience data may be more predictive of profitability of their risks than our analysis using, in part, general industry loss experience. For the same reason, should Congress repeal the McCarran-Ferguson Act, which provides an anti-trust exemption for the aggregation of loss data, and we are unable to access data from ISO, AAIS, and NCCI, we will be at a competitive disadvantage to larger insurers who have more loss experience data on their own customers and may not need aggregated industry loss data.

We depend on distribution partners.

We market and sell our insurance products through distribution partners who are not our employees. We believe that these partners will remain a significant force in overall insurance industry premium production because they can provide customers with a wider choice of insurance products than if they represented only one insurer. That, however, creates competition in our distribution channel and we must market our products and services to our distribution partners before they sell them to our mutual customers. Additionally, there has been a trend towards increased levels of consolidation of these distribution partners in the marketplace, which increases competition among fewer distributors. Our Standard Personal Lines production is further limited by the fact that independent retail insurance agencies only write approximately 35% of this business in the United States. Our financial condition and results of operations are tied to the successful marketing and sales efforts of our products by our distribution partners. In addition, under insurance laws and regulations and common law, we potentially can be held liable for business practices or actions taken by our distribution partners.

We are heavily regulated and changes in regulation may reduce our profitability, increase our capital requirements, and/or limit our growth.

Our Insurance Subsidiaries are heavily regulated by extensive laws and regulations that may change on short notice. The primary public policy behind insurance regulation is the protection of policyholders and claimants over all other constituencies, including shareholders. Historically by virtue of the McCarran-Ferguson Act, our Insurance Subsidiaries are primarily regulated by the states in which they are domiciled and licensed. State insurance regulation is generally uniform throughout the U.S. by virtue of similar laws and regulations required by the NAIC to accredit state insurance departments so their examinations can be given full faith and credit by other state regulators. Despite their general similarity, various provisions of these laws and regulations vary from state to state. At any given time, there may be various legislative and regulatory proposals in each of the 50 states and District of Columbia that, if enacted, may affect our Insurance Subsidiaries.

The broad regulatory, administrative, and supervisory powers of the various state departments of insurance include the following:

•

Related to our financial condition, review and approval of such matters as minimum capital and surplus requirements, standards of solvency, security deposits, methods of accounting, form and content of statutory financial statements, reserves for unpaid losses and loss adjustment expenses, reinsurance, payment of dividends and other distributions to shareholders, periodic financial examinations, and annual and other report filings.

•

Related to our general business, review and approval of such matters as certificates of authority and other insurance company licenses, licensing and compensation of distribution partners, premium rates (which may not be excessive, inadequate, or unfairly discriminatory), policy forms, policy terminations, reporting of statistical information regarding our premiums and losses, periodic market conduct examinations, unfair trade practices, participation in mandatory shared market mechanisms, such as assigned risk pools and reinsurance pools, participation in mandatory state guaranty funds, and mandated continuing workers compensation coverage post-termination of employment.

•

Related to our ownership of the Insurance Subsidiaries, we are required to register as an insurance holding company system in each state where an insurance subsidiary is domiciled and report information concerning all of our operations that may materially affect the operations, management, or financial condition of the insurers. As an insurance holding company, the appropriate state regulatory authority may: (i) examine our Insurance Subsidiaries or us at any time; (ii) require disclosure or prior approval of material transactions of any of the Insurance Subsidiaries with its affiliates; and (iii) require prior approval or notice of certain transactions, such as payment of dividends or distributions to us.

Although Congress has largely delegated insurance regulation to the various states by virtue of the McCarran-Ferguson Act, we are also subject to federal legislation and administrative policies, such as disclosure under the securities laws, including the Sarbanes-Oxley Act and the Dodd-Frank Act, TRIPRA, OFAC, and various privacy laws, including the Gramm-Leach-Bliley Act, the Fair Credit Reporting Act, the Drivers Privacy Protection Act, the Health Insurance Portability and Accountability Act, and the policies of the Federal Trade Commission. As a result of issuing workers compensation policies, we are subject to Mandatory Medicare Secondary Payer Reporting under the Medicare, Medicaid, and SCHIP Extension Act of 2007.

The European Union enacted Solvency II, which was implemented in 2016 and sets out new requirements for capital adequacy and risk management for insurers operating in Europe. The strengthened regime is intended to reduce the possibility of consumer loss or market disruption in insurance. In addition, in 2014, the International Association of Insurance Supervisors proposed Basic Capital Standards for Global Systemically Important Insurers as well as a uniform capital framework for internationally active insurers. Although Solvency II does not govern domestic American insurers, and we do not have international operations, we believe that development of global capital standards will influence the development of similar standards by domestic regulators. The NAIC has recently adopted ORSA, which requires insurers to maintain a framework for identifying, assessing, monitoring, managing, and reporting on the “material and relevant risks” associated with the insurer's (or insurance group's) current and future business plans. ORSA, which has been adopted by the state insurance regulators of our Insurance Subsidiaries, requires companies to file an internal assessment of their solvency with insurance regulators annually. Although no specific capital adequacy standard is currently articulated in ORSA, it is possible that such a standard will be developed over time and may increase insurers' minimum capital requirements, which could adversely impact our growth and return on equity.

We are subject to non-governmental regulators, such as the NASDAQ Stock Market and the New York Stock Exchange where we list our securities. Many of these regulators, to some degree, overlap with each other on various matters. They have different regulations on the same legal issues that are subject to their individual interpretative discretion. Consequently, we have the risk that one regulator’s position may conflict with another regulator’s position on the same issue. As compliance is generally reviewed in hindsight, we are subject to the risk that interpretations will change over time.

We believe we are in compliance with all laws and regulations that have a material effect on our results of operations, but the cost of complying with various, potentially conflicting laws and regulations, and changes in those laws and regulations could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Class action litigation could affect our business practices and financial results.

Our industry has been the target of class action litigation, including the following areas:


•	After-market parts;


•	Urban homeowner insurance underwriting practices, including those related to architectural or structural features and attempts by federal regulators to expand the Federal Housing Administration's guidelines to determine unfair discrimination;


•	Credit scoring and predictive modeling pricing;


•	Cybersecurity breaches;


•	Investment disclosure;


•	Managed care practices;


•	Timing and discounting of personal injury protection claims payments;


•	Direct repair shop utilization practices;


•	Flood insurance claim practices; and


•	Shareholder class action suits.

If we were to be named in such class action litigation, we could suffer reputational harm with purchasers of insurance and have increased litigation expenses that could have a materially adverse effect on our operations or results.

Risks Related to Our Investment Segment

We are exposed to interest rate risk in our investment portfolio.

We are exposed to interest rate risk primarily related to the market price, and cash flow variability, associated with changes in interest rates. A rise in interest rates may decrease the fair value of our existing fixed income investments and declines in interest rates may result in an increase in the fair value of our existing fixed income investments. Our fixed income investment portfolio, which currently has an effective duration of 3.8 years excluding short-term investments, contains interest rate sensitive instruments that may be adversely affected by changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond our control. A rise in interest rates would decrease the net unrealized gain position of the investment portfolio, partially offset by our ability to earn higher rates of return on funds reinvested in new investments. Conversely, a decline in interest rates would increase the net unrealized gain position of the investment portfolio, partially offset by lower rates of return on new and reinvested cash in the portfolio. Changes in interest rates have an effect on the calculated duration of certain securities in the portfolio. We seek to mitigate our interest rate risk associated with holding fixed income investments by monitoring and maintaining the average duration of our portfolio with a view toward achieving an adequate after-tax return without subjecting the portfolio to an unreasonable level of interest rate risk. This may include investing in floating rate securities and other shorter duration securities that exhibit low effective duration and interest rate risk, but expose the portfolio to other risks, including the risk of a change in credit spreads, liquidity spreads, and other factors that may adversely impact the value of the portfolio. Although we take measures to manage the economic risks of investing in a changing interest rate environment, we may not be able to mitigate the interest rate risk of our assets relative to our liabilities, particularly our loss reserves. In addition, our pension and post-retirement benefit obligations include a discount rate assumption, which is an important element of expense and/or liability measurement. Changes in the discount rate assumption could materially impact our pension and post-retirement life valuation.

We are exposed to credit risk in our investment portfolio.

The value of our investment portfolio is subject to credit risk from the issuers and/or guarantors of the securities in the portfolio, other counterparties in certain transactions and, for certain securities, insurers that guarantee specific issuer’s obligations. Defaults by the issuer or an issuer’s guarantor, insurer, or other counterparties regarding any of our investments, could reduce our net investment income and net realized investment gains or result in investment losses. We are subject to the risk that the issuers, or guarantors, of fixed income securities we own may default on principal and interest payments due under the terms of the securities. At December 31, 2016, our fixed income securities portfolio represented approximately

92% of our total invested assets, of which approximately 97% were investment grade and 3% were below investment grade rated, resulting in an average credit rating of AA- of the fixed income securities portfolio. Over time, our exposure to below investment grade securities and other credit sensitive risk assets may fluctuate as we continue to diversify the portfolio and take advantage of opportunities to add or reduce risk commensurate with our risk-taking capacity and market conditions. The occurrence of a major economic downturn, acts of corporate malfeasance, widening credit spreads, budgetary deficits, municipal bankruptcies spurred by, among other things, pension funding issues, or other events that adversely affect the issuers or guarantors of these securities could cause the value of our fixed income securities portfolio and our net income to decline and the default rate of our fixed income securities portfolio to increase.

With economic uncertainty, credit quality of issuers or guarantors could be adversely affected and a ratings downgrade of the issuers or guarantors of the securities in our portfolio could cause the value of our fixed income securities portfolio and our net income to decrease. As our stockholders' equity is leveraged at 3.5:1 to our investment portfolio, a reduction in the value of our investment portfolio could have a material adverse effect on our business, results of operations, financial condition, and debt ratings. Levels of write-downs are impacted by our assessment of the impairment, including a review of the underlying collateral of structured securities, and our intent and ability to hold securities that have declined in value until recovery. If we reposition or realign portions of the portfolio so that we determine not to hold certain securities in an unrealized loss position to recovery, we will incur an OTTI charge. For further information regarding credit and interest rate risk, see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk.” of this Form 10-K.

Our statutory surplus may be materially affected by rating downgrades on investments held in our portfolio.

We are exposed to significant financial and capital markets risks, primarily relating to interest rates, credit spreads, equity prices, and the change in market value of our alternative investment portfolio. A decline in both income and our investment

portfolio asset values could occur as a result of, among other things, a decrease in market liquidity, fluctuations in interest rates, decreased dividend payment rates, negative market perception of credit risk with respect to types of securities in our portfolio, a decline in the performance of the underlying collateral of our structured securities, reduced returns on our alternative investment portfolio, or general market conditions. A global decline in asset values will be more amplified in our financial condition, as our statutory surplus is leveraged at a 3.4:1 ratio to our investment portfolio.

With economic uncertainty, the credit quality and ratings of securities in our portfolio could be adversely affected. The NAIC could potentially apply a more adverse class code on a security than was originally assigned, which could adversely affect statutory surplus because securities with NAIC class codes three through six require securities to be marked-to-market for statutory accounting purposes, as compared to securities with NAIC class codes of one or two that are carried at amortized cost.

There can be no assurance that the actions of the U.S. Government, Federal Reserve, and other governmental and regulatory bodies will achieve their intended effect.

Over the past several years, the Federal Reserve has taken a number of actions related to interest rates and purchasing of financial instruments intended to spur economic recovery. The Federal Reserve's policy of quantitative easing and low interest rates since the financial crisis of 2008 have had an adverse effect on our investment income, as higher yielding securities mature and we reinvest the proceeds at lower yields. In December 2015 and again in December 2016, the Federal Reserve increased the Federal Fund Rate by 25 basis points each. It is unclear whether the Federal Reserve's economic stimulus actions will produce the desired results. The impact of these actions could materially and adversely affect our financial condition and the trading price of our common stock. In the event of future material deterioration in business conditions, we may need to raise additional capital or consider other transactions to manage our capital position.

In addition, our investment activities are subject to extensive laws and regulations that are administered and enforced by a number of different governmental authorities and non-governmental self-regulatory agencies. In light of the current economic conditions, some of these authorities have implemented, or may in the future implement, new or enhanced regulatory requirements, such as those included in the Dodd-Frank Act, intended to restore confidence in financial institutions and reduce the likelihood of similar economic events in the future. These authorities may seek to exercise their supervisory and enforcement authority in new or more robust ways. Such events could affect the way we conduct our business and manage our capital, and may require us to satisfy increased capital requirements. These developments, if they occurred, could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

We are subject to the types of risks inherent in investing in private limited partnerships.

Our other investments include investments in private limited partnerships that invest in various strategies, such as private equity, private credit, and real assets. Since these partnerships’ underlying investments consist primarily of assets or liabilities for which there are no quoted prices in active markets for the same or similar assets, the valuation of interests in these partnerships is subject to a higher level of subjectivity and unobservable inputs than substantially all of our other investments and as such, is subject to greater scrutiny and reconsideration from one reporting period to the next. As these investments are recorded under the equity method of accounting, any decreases in the valuation of these investments would negatively impact our results of operations. We currently expect to increase our allocation to these investments, which may result in additional variability in our net investment income.

We value our investments using methodologies, estimations, and assumptions that are subject to differing interpretations. Changes in these interpretations could result in fluctuations in the valuations of our investments that may adversely affect our results of operations or financial condition.

Fixed income, equity, and short-term investments, which are reported at fair value on our Consolidated Balance Sheet, represented the majority of our total cash and invested assets as of December 31, 2016. As required under accounting rules, we have categorized these securities into a three-level hierarchy, based on the priority of the inputs to the respective valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next priority is to quoted prices in markets that are not active or inputs that are observable either directly or indirectly, including quoted prices for similar assets or liabilities or in markets that are not active and other inputs that can be derived principally from, or corroborated by, observable market data for substantially the full term of the assets or liabilities (Level 2). The lowest priority in the fair value hierarchy is to unobservable inputs supported by little or no market activity and that reflect the reporting entity’s own assumptions about the exit price, including assumptions that market participants would use in pricing the asset or liability (Level 3).

An asset or liability’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. We generally use an independent pricing service and broker quotes to price our investment securities. At December 31, 2016, approximately 7% and 92% of these securities represented Level 1 and Level 2, respectively. However, prices provided by independent pricing services and brokers can vary widely even for the same security. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within our consolidated financial statements (“Financial Statements”) and the period-to-period changes in value could vary significantly. Decreases in value may result in an increase in non-cash OTTI charges, which could have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

The determination of the amount of impairments taken on our investments is highly subjective and could materially impact our results of operations or our financial position.

The determination of the amount of impairments taken on our investments is based on our periodic evaluation and assessment of our investments and known and inherent risks associated with the various asset classes. Such evaluations and assessments are revised as conditions change and new information becomes available. Management updates its evaluations regularly and reflects changes in impairments as such evaluations are revised. There can be no assurance that management has accurately assessed the level of impairments taken as reflected in our Financial Statements. Furthermore, additional impairments may need to be taken in the future. It is possible that interest rates, which are at historic lows, will increase which will result in a reduction in net unrealized gains and may result in net unrealized losses associated with declines in value strictly related to such interest rate movements. It is possible that this could result in realized losses if we sell such securities or possibly more OTTI if we determine we do not have the ability and intent to hold those securities until they recover in value. In addition, we recently hired several new investment managers and expect them to take a more active approach to managing our fixed income securities portfolio. As a result, we expect our OTTI to increase in coming periods based on an increase in securities that we may intend to sell despite being in an unrealized loss position. Historical trends may not be indicative of future impairments. For further information regarding our evaluation and considerations for determining whether a security is other-than-temporarily impaired, please refer to “Critical Accounting Policies and Estimates” in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” of this Form 10-K.

Risks Related to Our Corporate Structure and Governance

We are a holding company and our ability to declare dividends to our shareholders, pay indebtedness, and enter into affiliate transactions may be limited because our Insurance Subsidiaries are regulated.

Restrictions on the ability of the Insurance Subsidiaries to pay dividends, make loans or advances to us, or enter into transactions with affiliates may materially affect our ability to pay dividends on our common stock or repay our indebtedness.

As of December 31, 2016, the Parent had retained earnings of $1.5 billion. Of this amount, $1.4 billion was related to investments in our Insurance Subsidiaries. The Insurance Subsidiaries have the ability to provide for $193 million in annual ordinary dividends to us in 2017 under applicable state regulation; however, as they are regulated entities, their ability to pay dividends or make loans or advances to us is subject to the approval or review of the insurance regulators in the states where they are domiciled. The standards for review of such transactions are whether: (i) the terms and charges are fair and reasonable; and (ii) after the transaction, the Insurance Subsidiary's surplus for policyholders is reasonable in relation to its outstanding liabilities and financial needs. Although dividends and loans to us from our Insurance Subsidiaries historically have been approved, we can make no assurance that future dividends and loans will be approved. For additional details regarding dividend restrictions, see Note 19. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Because we are an insurance holding company and a New Jersey corporation, we may be less attractive to potential acquirers and the value of our common stock could be adversely affected.

Because we are an insurance holding company that owns insurance subsidiaries, anyone who seeks to acquire 10% or more of our stock must seek prior approval from the insurance regulators in the states in which the subsidiaries are organized and file extensive information regarding their business operations and finances.

Provisions in our Amended and Restated Certificate of Incorporation may discourage, delay, or prevent us from being acquired, including:


•	Supermajority shareholder voting requirements to approve certain business combinations with interested shareholders (as defined in the Amended and Restated Certificate of Incorporation) unless certain other conditions are satisfied; and


•	Supermajority shareholder voting requirements to amend the foregoing provisions in our Amended and Restated Certificate of Incorporation.

In addition to the requirements in our Amended and Restated Certificate of Incorporation, the New Jersey Shareholders’ Protection Act also prohibits us from engaging in certain business combinations with interested stockholders (as defined in the statute), in certain instances for a five-year period, and in other instances indefinitely, unless certain conditions are satisfied. These conditions may relate to, among other things, the interested stockholder’s acquisition of stock, the approval of the business combination by disinterested members of our Board of Directors and disinterested stockholders, and the price and payment of the consideration proposed in the business combination. Such conditions are in addition to those requirements set forth in our Amended and Restated Certificate of Incorporation.

These provisions of our Amended and Restated Certificate of Incorporation and New Jersey law could have the effect of depriving our stockholders of an opportunity to receive a premium over our common stock’s prevailing market price in the event of a hostile takeover and may adversely affect the value of our common stock.

Risks Related to Our General Operations

The failure of our risk management strategies could have a material adverse effect on our financial condition or results of operations.

As an insurance provider, it is our business to take on risk from our customers. Our long-term strategy includes the use of above average operational leverage, which can be measured as the ratio of NPW to our equity or policyholders surplus. We balance operational leverage risk with a number of risk management strategies within our insurance operations to achieve a balance of growth and profit and to reduce our exposure. These strategies include, but are not limited to, the following:


•	Being disciplined in our underwriting practices;


•	Being prudent in our claims management practices, establishing adequate loss and loss expense reserves, and placing appropriate reliance on our claims analytics;


•	Continuing to develop and implement various underwriting tools and automated analytics to examine historical statistical data regarding our customers and their loss experience to: (i) classify such policies based on that information; (ii) apply that information to current and prospective accounts; and (iii) better predict account profitability;


•	Continuing to develop our customer experience platform as we grow in our understanding of customer segmentation;


•	Purchasing reinsurance and using catastrophe modeling; and


•	Being prudent in our financial planning process, which supports our underwriting strategies.

We also maintain a conservative approach to our investment portfolio management and employ risk management strategies that include, but are not limited to:


•	Being prudent in establishing our investment policy and appropriately diversifying our investments, which supports our liabilities and underwriting strategies;


•	Using complex financial and investment models to analyze historical investment performance and predict future investment performance under a variety of scenarios using asset concentration, asset volatility, asset correlation, and systematic risk; and


•	Closely monitoring investment performance, general economic and financial conditions, and other relevant factors.

All of these strategies have inherent limitations. We cannot be certain that an event or series of unanticipated events will not occur and result in losses greater than we expect and have a material adverse effect on our results of operations, liquidity, financial condition, financial strength, and debt ratings.

Operational risks, including human or systems failures, are inherent in our business.

Operational risks and losses can result from, among other things, fraud, errors, failure to document transactions properly or to obtain proper internal authorization, failure to comply with regulatory requirements, information technology failures, or external events.

We believe that our predictive models for underwriting, claims, and catastrophe losses, as well as our business analytics and our information technology and application systems are critical to our business. We expect our information technology and application systems to remain an important part of our underwriting process and our ability to compete successfully. A major defect or failure in our internal controls or information technology and application systems could: (i) result in management distraction; (ii) harm our reputation; or (iii) increase our expenses. We believe appropriate controls and mitigation procedures are in place to prevent significant risk of a defect in our internal controls around our information technology and application systems, but internal controls provide only a reasonable, not absolute, assurance as to the absence of errors or irregularities and any ineffectiveness of such controls and procedures could have a significant and negative effect on our business.

Rapid development of new technologies may result in an unexpected impact on our business and insurance industry overall.

Development of new technologies continues to impact all aspects of business and individuals’ lives at rapid speed. Often such developments are positive and gradually improve standards of living and speed of communications, and allow for the development of more efficient processes. The rapid development of new technologies, however, also presents challenges and risks. Examples of such emerging risks include, but are not limited to:

•

Change in exposures and claims frequency and/or severity due to unanticipated consequences of new technologies and their use. For example, technologies have been developed and are being tested for autonomous self-driving automobiles. It is unclear and we cannot predict the corresponding severity or cost of automobile claims. It is possible that these technological developments will affect the profitability and demand for automobile insurance.

•

Changes in how insurance products are marketed and purchased due to the availability of new technologies and changes in customer expectations. For example, comparative rating technologies, which are widely used in personal lines insurance, facilitate the process of efficiently generating quotes from multiple insurance companies. This technology makes differentiation other than on pricing more difficult and has increased price comparison and resulted in a higher level of quote activity with a lower percentage of quotes becoming new business written. These trends may continue to accelerate and may affect other lines of business, which could put pressure on our future profitability.


•	New technologies may require the development of new insurance products without the support of sufficient historical claims data for us to continue to compete effectively for our distribution partners' business and customers.

We depend on key personnel.

To a large extent, our business' success depends on our ability to attract and retain key employees. Competition to attract and retain key personnel is intense. While we have employment agreements with certain key managers, all of our employees are at-will employees and we cannot ensure that we will be able to attract and retain key personnel. As of December 31, 2016, our workforce had an average age of approximately 47 and approximately 17% of our workforce was retirement eligible.

We are subject to a variety of modeling risks, which could have a material adverse impact on our business results.

We rely on complex financial models, such as predictive underwriting models, a claims fraud model, third party catastrophe models, an enterprise risk management capital model, and modeling tools used by our investment managers, which have been developed internally or by third parties to analyze historical loss costs and pricing, trends in claims severity and frequency, the occurrence of catastrophe losses, investment performance, and portfolio risk. Flaws in these financial models, or faulty assumptions used by these financial models, could lead to increased losses. We believe that statistical models alone do not provide a reliable method for monitoring and controlling risk. Therefore, such models are tools and do not substitute for the experience or judgment of senior management.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our main office is located in Branchville, New Jersey on a site owned by a subsidiary with approximately 114 acres and 315,000 square feet of operational space. We lease all of our other facilities. The principal office locations related to our insurance segments are described in the “Geographic Markets” section of Item 1. “Business.” of this Form 10-K. We believe our facilities provide adequate space for our present needs and that additional space, if needed, would be available on reasonable terms.

Item 3. Legal Proceedings.

In the ordinary course of conducting business, we are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving our Insurance Subsidiaries as either: (i) liability insurers defending or providing indemnity for third-party claims brought against our customers; or (ii) insurers defending first-party coverage claims brought against them. We account for such activity through the establishment of unpaid losses and loss expense reserves. We expect that any potential ultimate liability in such ordinary course claims litigation will not be material to our consolidated financial condition, results of operations, or cash flows after consideration of provisions made for potential losses and costs of defense.

named from time-to-time in individual actions seeking extra-contractual damages, punitive damages, or penalties, some of which allege bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that any potential ultimate liability in any such lawsuit will not be material to our consolidated financial condition, after consideration of provisions made for estimated losses. Nonetheless, given the inherent unpredictability of litigation and the large or indeterminate amounts sought in certain of these actions, an adverse outcome in certain matters could possibly have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.

As of December 31, 2016, we do not believe the Company or any of the Insurance Subsidiaries was a defendant in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

First quarter	$	36.92	29.27	30.10	25.49
Second quarter	38.67		33.60	29.60	26.28
Third quarter	41.30		35.90	32.50	28.10
Fourth quarter	44.00		34.95	37.91	30.36

On February 14, 2017, the closing price of our common stock as reported on the NASDAQ Global Select Market was $43.20.

(b) Holders

We had 3,374 stockholders of record as of February 14, 2017 according to the records maintained by our transfer agent.

Dividends on shares of our common stock are declared and paid at the discretion of the Board based on our results of operations, financial condition, capital requirements, contractual restrictions, and other relevant factors. On October 26, 2016, the Board of Directors approved a 7% increase in our dividend to $0.16 per share. In addition, on February 2, 2017, the Board of Directors declared a $0.16 per share quarterly cash dividend on common stock that is payable March 1, 2017, to stockholders of record as of February 15, 2017. The following table provides information on the dividends declared for each quarterly period within our two most recent fiscal years:



Dividend Per Share	2016		2015
First quarter	$	0.15	0.14
Second quarter	0.15		0.14
Third quarter	0.15		0.14
Fourth quarter	0.16		0.15

Our ability to receive dividends, loans, or advances from our Insurance Subsidiaries is subject to the approval and/or review of the insurance regulators in the respective domiciliary states of our Insurance Subsidiaries. Such approval and/or review is made under the respective domiciliary states’ insurance holding company acts, which generally require that any transaction between related companies be fair and equitable to the insurance company and its policyholders. Although our dividends have historically been met with regulatory approval, there is no assurance that future dividends will be approved given current market conditions. We currently expect to continue to pay quarterly cash dividends on shares of our common stock in the future. For additional information, see Note 19. "Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Forward-looking Statements

Certain statements in this report, including information incorporated by reference, are “forward-looking statements” as that term is defined in the Private Securities Litigation Reform Act of 1995 (“PSLRA”). The PSLRA provides a safe harbor under the Securities Act of 1933, as amended, and the Exchange Act for forward-looking statements. These statements relate to our intentions, beliefs, projections, estimations or forecasts of future events or future financial performance and involve known and unknown risks, uncertainties and other factors that may cause us or the industry’s actual results, levels of activity, or performance to be materially different from those expressed or implied by the forward-looking statements. In some cases, forward-looking statements may be identified by use of the words such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” or “continue” or other comparable terminology. These statements are only predictions, and we can give no assurance that such expectations will prove to be correct. We undertake no obligation, other than as may be required under the federal securities laws, to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Factors that could cause our actual results to differ materially from those we have projected, forecasted or estimated in forward-looking statements are discussed in further detail in Item 1A. “Risk Factors.” of this Form 10-K. These risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time-to-time. We can neither predict such new risk factors nor can we assess the impact, if any, of such new risk factors on our businesses or the extent to which any factor or combination of factors may cause actual results to differ materially from those expressed or implied in any forward-looking statements in this report. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this report might not occur.

Introduction

We classify our business into four reportable segments, which are as follows:


•	Standard Commercial Lines - comprised of insurance products and services provided in the standard marketplace to our commercial enterprises, which are typically businesses, non-profit organizations, and local government agencies.


•	Standard Personal Lines - comprised of insurance products and services, including flood insurance coverage, provided primarily to individuals acquiring coverage in the standard marketplace.


•	Excess and surplus ("E&S") Lines - comprised of insurance products and services provided to customers who have not obtained coverage in the standard marketplace.


•	Investments - invests the premiums collected by our insurance operations, as well as amounts generated through our capital management strategies, which may include the issuance of debt and equity securities.

Our Standard Commercial and Standard Personal Lines products and services are written through our nine insurance subsidiaries, some of which write flood business through the Write Your Own ("WYO") program of the National Flood Insurance Program ("NFIP"). Our E&S Lines products and services are written through one subsidiary, Mesa Underwriters Specialty Insurance Company ("MUSIC"). This subsidiary provides us with a nationally-authorized non-admitted platform to offer insurance products and services to customers who have not obtained coverage in the standard marketplace.

Our ten insurance subsidiaries are collectively referred to as the "Insurance Subsidiaries."

The following is Management’s Discussion and Analysis (“MD&A”) of the consolidated results of operations and financial condition, as well as known trends and uncertainties, that may have a material impact in future periods.

In the MD&A, we will discuss and analyze the following:


•	Critical Accounting Policies and Estimates;


•	Financial Highlights of Results for Years Ended December 31, 2016, 2015, and 2014;


•	Results of Operations and Related Information by Segment;


•	Federal Income Taxes;


•	Financial Condition, Liquidity, and Capital Resources;


•	Off-Balance Sheet Arrangements;


•	Contractual Obligations, Contingent Liabilities, and Commitments; and


•	Ratings.

Critical Accounting Policies and Estimates

We have identified the policies and estimates described below as critical to our business operations and the understanding of the results of our operations. Our preparation of the Financial Statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of our Financial Statements, and the reported amounts of revenue and expenses during the reporting period. There can be no assurance that actual results will not differ from those estimates. Those estimates that were most critical to the preparation of the Financial Statements involved the following: (i) reserves for losses and loss expenses; (ii) pension and post-retirement benefit plan actuarial assumptions; (iii) investment valuation and other-than-temporary-impairments (“OTTI”); and (iv) reinsurance.

Reserves for Losses and Loss Expenses

Significant periods of time can elapse between the occurrence of an insured loss, the reporting of the loss to the insurer, and the insurer’s payment of that loss. To recognize liabilities for unpaid losses and loss expenses, insurers establish reserves as balance sheet liabilities representing an estimate of amounts needed to pay reported and unreported net losses and loss expenses. We had accrued $3.7 billion of gross loss and loss expense reserves and $3.1 billion of net loss and loss expense reserves at December 31, 2016. At December 31, 2015, these gross and net reserves were $3.5 billion and $3.0 billion, respectively.

The following tables provide case and incurred but not reported (“IBNR”) reserves for losses and loss expenses, and reinsurance recoverable on unpaid losses and loss expenses as of December 31, 2016 and 2015:



As of December 31, 2016

How reserves are established

When a claim is reported to us, claims personnel establish a “case reserve” for the estimated amount of the reported loss. The amount of the reserve is primarily based on a case-by-case evaluation of the type of claim involved, the circumstances surrounding each claim, and the policy provisions relating to the type of losses, less any amounts previously paid to the claimant. The estimate reflects the informed judgment of such personnel based on their knowledge, experience, and general insurance reserving practices. Until the claim is resolved, these estimates are revised as deemed appropriate by the responsible claims personnel based on subsequent developments and periodic reviews of the case.

Using generally accepted actuarial reserving techniques, we project our estimate of ultimate losses and loss expenses at each reporting date. Our IBNR reserve is the difference between the projected ultimate losses and loss expenses incurred and the sum of: (i) case losses and loss expense reserves; and (ii) paid losses and loss expenses. The actuarial techniques used in determining ultimate losses are part of a comprehensive reserving process that includes two primary components. The first component is a detailed quarterly reserve analysis performed by our internal actuarial staff. In completing this analysis, the actuaries must gather substantially similar data in sufficient volume to ensure statistical credibility of the data, while maintaining appropriate differentiation. This process defines the reserving segments, to which various actuarial projection methods are applied. When applying these methods, the actuaries are required to make numerous assumptions including, for example, the selection of loss and loss expense development factors and the weight to be applied to each individual projection method. These methods include paid and incurred versions for the following: loss and loss expense development, Bornhuetter-Ferguson, Berquist-Sherman, and frequency/severity modeling (chain-ladder approach). The second component of the analysis is the projection of the expected ultimate loss and loss expense ratio for each line of business for the current accident year. This projection is part of our planning process wherein we review and update expected loss and loss expense ratios each quarter. This review includes actual versus expected pricing changes, loss and loss expense trend assumptions, and updated prior period loss and loss expense ratios from the most recent quarterly reserve analysis.

In addition to the quarterly reserve analysis, a range of possible IBNR reserves is estimated annually and continually considered, among other factors, in establishing IBNR for each reporting period. Loss and loss expense trends are also considered, which include, but are not limited to, large loss activity, asbestos and environmental claim activity, large case reserve additions or reductions for prior accident years, and reinsurance recoverable issues. We also consider factors such as: (i) per claim information; (ii) company and industry historical loss experience; (iii) legislative enactments, judicial decisions,

legal developments in the imposition of damages, and changes in political attitudes; and (iv) trends in general economic conditions, including the effects of inflation. Based on the consideration of the range of possible IBNR reserves, recent loss and loss expense trends, uncertainty associated with actuarial assumptions, and other factors, IBNR is established and the ultimate net liability for losses and loss expenses is determined. Such an assessment requires considerable judgment given that it is frequently not possible to determine whether a change in the data is an anomaly until sometime after the event. Even if a change is determined to be permanent, it is not always possible to reliably determine the extent of the change until sometime later. There is no precise method for subsequently evaluating the impact of any specific factor on the adequacy of reserves because the eventual deficiency or redundancy is affected by many factors. The changes in these estimates, resulting from the continuous review process and the differences between estimates and ultimate payments, are reflected in the Consolidated Statements of Income for the period in which such estimates are changed. Any changes in the liability estimate may be material to the results of operations in future periods. In addition to our internal review, statutory regulation requires us to have a Statement of Actuarial Opinion issued annually on our statutory reserve adequacy. We engage an independent actuary to issue this opinion based on their independent review.

Range of reasonable reserves

We have estimated a range of reasonably possible reserves for net loss and loss expense claims to be $2,780 million to $3,237 million at December 31, 2016, which compares to $2,694 million to $3,136 million at December 31, 2015. These ranges reflect low and high reasonable reserve estimates, which were selected primarily by considering the range of indications calculated using generally accepted actuarial techniques. Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for predicting future events. Although these ranges reflect likely scenarios, it is possible that the final outcomes may fall above or below these amounts. The ranges do not include a provision for potential increases or decreases associated with asbestos, environmental, and other continuous exposure claims, as traditional actuarial techniques cannot be effectively applied to these exposures.

In 2016, we experienced overall net favorable loss development of $65.8 million, compared to $69.0 million in 2015, and $59.3 million in 2014. The following table summarizes prior year development by line of business:

Major developments related to loss and loss expense reserve estimates and uncertainty

The Insurance Subsidiaries are multi-state, multi-line property and casualty insurance companies and, as such, are subject to reserve uncertainty stemming from a variety of sources. These uncertainties are considered at each step in the process of establishing loss and loss expense reserves. As market conditions change, certain developments may occur that increase or decrease the amount of uncertainty. These developments include impacts within our own paid and reported loss and loss expense experience, as well as other internal and external factors that have not yet manifested within our data, but may do so in the future. All of these developments are considered when establishing loss and loss expense reserves, and in estimating the range of reasonable reserves.

For the past eleven years, the Insurance Subsidiaries have experienced net favorable prior accident year loss and loss expense development, although there can be no assurance that this will continue, or that we may experience adverse prior accident year loss and loss expense development in future periods. Over the past three years, contributions to the favorable emergence have come from different lines of business at different points in time. The greater contributions have generally come from the longer tailed casualty lines, primarily due to their associated volume of reserves and the inherent uncertainty of the longer claims settlement process, although this has been offset in part by adverse prior accident year loss and loss expense development within certain lines such as commercial and personal auto liability and E&S.

A more detailed discussion of recent developments, by line of business, follows.

Standard Market General Liability Line of Business

At December 31, 2016, our general liability line of business had recorded reserves, net of reinsurance, of $1.1 billion, which represented 36% of our total net reserves. In 2016, this line experienced favorable development of $45.0 million, attributable mainly to lower than anticipated claims severities in accident years 2008 through 2013 and 2015.

During 2015, this line experienced favorable development of $51.0 million, attributable mainly to accident years 2013 and prior. This was primarily driven by severities that continued to develop lower than expected, within both the premises and operations and products liability coverages. In addition, the reduction in frequencies that we had seen in the immediately prior accident years continued into accident year 2015.

Standard Market Workers Compensation Line of Business

At December 31, 2016, our workers compensation line of business recorded reserves, net of reinsurance, of $1.0 billion, which represented 32% of our total net reserves. During 2016, this line experienced favorable development of $56.0 million driven by accident years 2014 and prior. During 2015, this line experienced favorable development of $37.0 million driven by virtually all prior accident years. The results over the past two years represent a change compared to 2014, during which this line experienced no development on prior accident years. During 2016, this line showed continued reductions in paid and reported loss amounts, due, in part, to: (i) lower medical inflation than originally anticipated; (ii) our proactive underwriting actions in recent years; and (iii) various significant claims initiatives that we implemented, including the centralization of our workers compensation claims handling in Charlotte, North Carolina, more favorable Preferred Provider Organizations ("PPO") contracts, greater PPO penetration, and more proactive case management in the areas of medical, pharmaceutical, and physical therapy treatments. Jurisdictionally trained and aligned medical only and lost-time adjusters manage non-complex workers compensation claims within our footprint. Claims with high exposure and/or significant escalation risk are referred to the workers compensation strategic case management unit.

While we believe these changes are significant drivers of our improved loss experience, there is always risk associated with change. Most notably, these changes in operations may inherently change paid and reported development patterns. While our reserve analyses incorporate methods that adjust for these changes, there nevertheless remains a greater risk in the estimated reserves.

In addition to the uncertainties associated with actuarial assumptions and methodologies described above, the workers compensation line of business can be impacted by a variety of issues, such as the following:

Unexpected changes in medical cost inflation - The industry is currently experiencing a period of lower claim cost inflation. Changes in our historical workers compensation medical costs, along with uncertainty regarding future medical inflation, creates the potential for additional variability in our reserves;

Changes in statutory workers compensation benefits - Benefit changes may be enacted that affect all outstanding claims, regardless of having occurred in the past. Depending upon the social and political climate, these changes may either increase or decrease associated claim costs;

Changes in utilization of the workers compensation system - These changes may be driven by economic, legislative, or other changes. For example, higher levels of unemployment could ultimately impact both the severity and frequency of workers compensation claims. In particular, during more difficult economic times, workers may be more likely to use the system, and less likely to return to work. Another example is the potential changes to federal healthcare laws, which, depending on the nature of the changes, may have either positive or negative impacts on workers compensation costs.

Changes in the economy could impact reserves in other ways. For example, in 2016, audit and endorsement activity resulted in additional premium of $22.6 million, and in 2015, audit and endorsement activity resulted in additional premium of $22.5 million. As premiums earned are used as a basis for setting initial reserves on the current accident year, our reserves could be impacted. While audit and endorsement premiums are modeled within our annual budgeting process, they remain uncertain, and therefore provide additional variability to the resulting loss and loss expense ratio estimates.

Standard Market Commercial Automobile Line of Business

At December 31, 2016, our commercial automobile line of business had recorded reserves, net of reinsurance, of $413 million, which represented 13% of our total net reserves. In 2016, this line experienced unfavorable development of $25.3 million, which was mainly driven by higher severity in accident year 2014 and higher frequency and severity in 2015.

In 2015, this line experienced unfavorable development of $2.2 million, which was driven by bodily injury liability for accident years 2013 and 2014. This was partially offset by favorable development in accident years 2010 and 2011.

For the industry, the commercial automobile line has experienced unfavorable trends in recent years, in both its casualty and property coverages. While no direct causal relationships can be drawn, increased frequencies may be due to increased miles driven, which may be the result of the economic recovery and lower gasoline prices, as well as distracted driving. Rising severities may be the result of the increasing complexity of vehicles and the technology they incorporate, which results in increased repair costs.

We are currently taking actions to improve the profitability of this line of business, including:


•	Reducing premium leakage by improving the quality of our rating information. This includes validating application information using third party data and using more detailed driver information.


•	Co-underwriting selected higher hazard classes by the field and home office, providing better recognition of risk drivers and improved pricing. This includes increasing rate targets on these exposures.


•	Continuing to leverage our predictive modeling and analytical capabilities to provide more granular and actionable rate per exposure unit guidance on new business opportunities, while also developing and executing targeted rate change and underwriting actions on our renewal portfolio.

Standard Market Personal Automobile Line of Business

At December 31, 2016, our personal automobile line of business had recorded reserves, net of reinsurance, of $96 million, which represented 3% of our total net reserves. In 2016, this line experienced unfavorable development of $1.0 million. While this development is relatively neutral overall, it results from an increase in accident year 2015, largely offset by a decrease in accident year 2014. This line experienced unfavorable prior year development of $0.4 million in 2015. We continue to recalibrate our predictive models, as well as refine our underwriting and pricing approaches. While we believe these changes will ultimately lead to improved profitability and greater stability, they may impact paid and reported development patterns, thereby increasing the uncertainty in the reserves in the near-term.

E&S Lines

At December 31, 2016, our E&S Lines had recorded reserves, net of reinsurance, of $281 million, which represented 9% of our total net reserves. In 2016, these lines experienced unfavorable development of $7.1 million, mostly associated with accident year 2014. In 2015, these lines experienced unfavorable development of $15.5 million, associated with accident years 2012 through 2014. Since we have limited historical loss experience in this segment, our reserve estimates are partially based on development patterns of companies that have similar operations. Therefore, these estimates are subject to somewhat greater uncertainty than the comparable standard operations lines of business. As our own experience matures, we will continue to place greater weight upon it, and less weight upon the surrogate patterns.

In order to improve outcomes, we have taken the following actions related to E&S claims:


•	Effective January 1, 2015, the E&S Claims operation began reporting through our Corporate Claims division in Charlotte, North Carolina.


•	Complex claims were integrated into our standard lines CCU in August 2015.


•	Potential complex liability claims are now systematically identified and referred to our CCU.


•	Effective January 1, 2016, the E&S Claims operation in Scottsdale, Arizona was closed and all open and new claims are now handled out of our standard lines regional claims offices by dedicated E&S claims personnel.


•	Claims have been segregated into “litigated” versus “non-litigated.” Separate claim handling teams have been created, with the required skill sets, to appropriately handle these two types of claims.


•	Implemented the following expense improvement initiatives regarding outside adjusters and legal counsel:


◦	Maximized use of staff counsel when geographically possible;


◦	Utilized staff coverage attorney for coverage reviews;


◦	Heightened focus on legal budgeting and expense management;


◦	Required panel counsel firms to use our electronic legal billing and budgeting system to better manage budgets and expenses associated with litigation; and


◦	Implemented a panel counsel review process.


•	In addition to the expense improvement initiatives above, we anticipate implementing the following in 2017 to further improve benefits:


◦	Expanding the use of staff counsel in high volume, high cost locations; and


◦	Expanding the use of alternative fee arrangements with panel counsel.


•	For property claims, similar corporate oversight and referrals have been implemented. In addition, large losses are now adjusted by or overseen by Standard Lines property personnel.

We believe that the actions above will not only lead to earlier identification of severe claims, but also earlier claims resolutions with improved outcomes. We have begun to see the benefits of the actions above, through significantly lower loss adjustment expenses.

Other impacts creating additional loss and loss expense reserve uncertainty

Claims Initiative Impacts

In addition to the line of business specific issues mentioned above, our lines of business have been impacted by a number of initiatives undertaken by our Claims Department that have resulted in variability, or shifts, in the average level of case reserves. Some of these initiatives have also impacted claims settlement rates. These changes affect the data upon which the ultimate loss and loss expense projections are made. While these changes in case reserve levels and settlement rates increase the uncertainty in the short run, we expect the longer-term benefit will be a more refined management of the claims process.

Some of the specific actions implemented over the past several years, other than those regarding E&S as discussed above, are as follows:


•	Increased focus on reducing workers compensation medical costs through more favorable PPO contracts and greater PPO penetration.


•	A more comprehensive approach for handling workers compensation claims, with an emphasis towards improving recovery times, allowing for earlier “return-to-work.” This involves elevated and proactive case management in the areas of medical, pharmaceutical, and physical therapy treatments.


•	The continued use of our CCU, to which all significant and complex liability claims are assigned. This unit has been staffed with personnel that have significant experience in handling and settling these types of claims.


•	The strategic realignment of our CMS model to handle property claims under $5,000.

•

The continued use of our PCSs and our LLU. Our PCSs handle claims between $5,000 and $100,000, while the LLU handles claims above $100,000. Both groups form the core of our catastrophe response team. During 2016, we began increasing the number of property claims specialists to respond to property claims with higher severity and/or complexity. This provides us with more staff to respond to claim volume, including the fluctuations that result from catastrophes, while ensuring we have the highest level of property expertise available to apply to our more complex claims.


•	Continued efforts in the areas of fraud investigation and salvage/subrogation recoveries. These efforts have been supported by the introduction of predictive models that allow us to better focus our efforts.

Our internal reserve analyses incorporate actuarial projection methods, which make adjustments for changes in case reserve adequacy and claims settlement rates. These methods adjust our historical loss experience to the current level of case adequacy or settlement rate, which provides a more consistent basis for projecting future development patterns. These methods have their own assumptions and judgments associated with them, so as with any projection method, they are not definitive in and of themselves. Furthermore, given that the expected benefits from our claims initiatives take time to fully manifest, we do not take full credit for the anticipated benefit in establishing our loss and loss expense reserves. These initiatives may prove more or less beneficial than currently reflected, which will affect development in future years. Our various projection methods provide an indication of these potential future impacts. These impacts would be greatest within our larger reserve lines of workers compensation, general liability, and commercial automobile liability, within the more recent accident years.

Economic Inflationary Impacts

Although inflationary volatility is expected to be low in the near term, current United States monetary policy and global economic conditions bring additional uncertainty in the long-term given the length of time required for claim settlement and the impact of medical cost trends relating to longer-tail liability and workers compensation claims. Uncertainty regarding future inflation or deflation creates the potential for additional volatility in our reserves for these lines of business.

Sensitivity analysis: Potential impact on reserve uncertainty due to changes in key assumptions

Our process to establish reserves includes a variety of key assumptions, including, but not limited to, the following:


•	The selection of loss and loss expense development factors;


•	The weight to be applied to each individual actuarial projection method;


•	Projected future loss trends; and


•	Expected ultimate loss and loss expense ratios for the current accident year.

The importance of any single assumption depends on several considerations, such as the line of business and the accident year. If the actual experience emerges differently than the assumptions used in the process to establish reserves, changes in our reserve estimate are possible and may be material to the results of operations in future periods. Set forth below are sensitivity tests that highlight potential impacts to loss and loss expense reserves under different scenarios, for the major casualty lines of business. These tests consider each assumption and line of business individually, without any consideration of correlation between lines of business and accident years. Therefore, the results in the tables below do not constitute an actuarial range. While the figures represent possible impacts from variations in key assumptions as identified by management, there is no assurance that the future emergence of our loss and loss expense experience will be consistent with either our current or alternative sets of assumptions.

While the sources of variability discussed above are generated by different underlying trends and operational changes, they ultimately manifest themselves as changes in the expected loss and loss expense development patterns. These patterns are a key assumption in the reserving process. In addition to the expected development patterns, the expected loss and loss expense ratios are another key assumption in the reserving process. These expected ratios are developed through a rigorous process of projecting recent accident years' experience to an ultimate settlement basis, and then adjusting it to the current accident year's pricing and loss cost levels. Impact from changes in the underwriting portfolio and changes in claims handling practices are also quantified and reflected, where appropriate. As is the case with all estimates, the ultimate loss and loss expense ratios may differ from those currently estimated.

The sensitivities of loss and loss expense reserves to these key assumptions are illustrated below for the major casualty lines. The first table shows the estimated impacts from changes in expected reported loss and loss expense development patterns. It shows reserve impacts by line of business if the actual calendar year incurred amounts are greater or less than current expectations by the selected percentages. While the selected percentages by line are judgmentally based, they reflect the relative contribution of the specific line of business to the overall reserve range. The second table shows the estimated impacts from changes to the expected loss and loss expense ratios for the current accident year. It shows reserve impacts by line of business if the expected loss and loss expense ratios for the current accident year are greater or less than current expectations by the selected percentages.



Reserve Impacts of Changes to Prior Years Expected Loss and Loss Expense Reporting Patterns
($ in millions)	Percentage Decrease/Increase		(Decrease) to Future Calendar Year Reported			Increase to Future Calendar Year Reported
General liability	7	%	$	(80	)	$	80
Workers compensation	7		(70		)	70
Commercial automobile liability	10		(35		)	35
Personal automobile liability	15		(10		)	10
E&S liability	10		(35		)	35



Reserve Impacts of Changes to Current Year Expected Ultimate Loss and Loss Expense Ratios
($ in millions)	Percentage Decrease/Increase		(Decrease) to Current Accident Year Expected Loss and Loss Expense Ratio			Increase to Current Accident Year Expected Loss and Loss Expense Ratio
General liability	7	pts	$	(37	)	$	37
Workers compensation	7		(22		)	22
Commercial automobile liability	7		(21		)	21
Personal automobile liability	7		(6		)	6
E&S liability	7		(11		)	11

Note that there is some overlap between the impacts in the two tables. For example, increases in the calendar year development would ultimately impact our view of the current accident year's loss and loss expense ratios. Nevertheless, these tables provide perspective into the sensitivity of each of these key assumptions.

Asbestos and Environmental Reserves

Our general liability, excess liability, and homeowners reserves include exposure to asbestos and environmental claims. Our exposure to environmental liability is primarily due to: (i) landfill exposures from policies written prior to the absolute pollution endorsement in the mid 1980s; and (ii) underground storage tank leaks mainly from New Jersey homeowners policies. These environmental claims stem primarily from insured exposures in municipal government, small non-manufacturing commercial risks, and homeowners policies.

The total carried net losses and loss expense reserves for these claims were $22.7 million as of December 31, 2016 and $23.2 million as of December 31, 2015. The emergence of these claims occurs over an extended period and is highly unpredictable. For example, within our Standard Commercial Lines book, certain landfill sites are included on the National Priorities List (“NPL”) by the United States Environmental Protection Agency (“USEPA”). Once on the NPL, the USEPA determines an appropriate remediation plan for these sites. A landfill can remain on the NPL for many years until final approval for the removal of the site is granted from the USEPA. The USEPA has the authority to re-open previously closed sites and return them to the NPL. We currently have reserves for nine customers related to six sites on the NPL.

“Asbestos claims” are claims for bodily injury alleged to have occurred from exposure to asbestos-containing products. Our primary exposure arises from insuring various distributors of asbestos-containing products, such as electrical and plumbing materials. At December 31, 2016, asbestos claims constituted 29% of our $22.7 million net asbestos and environmental reserves, compared to 29% of our $23.2 million net asbestos and environmental reserves at December 31, 2015.

“Environmental claims” are claims alleging bodily injury or property damage from pollution or other environmental contaminants other than asbestos. These claims include landfills and leaking underground storage tanks. Our landfill exposure lies largely in policies written for municipal governments, in their operation or maintenance of certain public lands. In addition to landfill exposures, in recent years, we have experienced a relatively consistent level of reported losses in the homeowners line of business related to claims for groundwater contamination from leaking underground heating oil storage tanks in New Jersey. In 2007, we instituted a fuel oil system exclusion on our New Jersey homeowners policies that limits our exposure to leaking underground storage tanks for certain customers. At that time, existing customers were offered a one-time opportunity to buy back oil tank liability coverage. The exclusion applies to all new homeowners policies in New Jersey. These customers are eligible for the buy-back option only if the tank meets specific eligibility criteria.

Our asbestos and environmental claims are handled in our centralized and specialized asbestos and environmental claim unit. Case reserves for these exposures are evaluated on a claim-by-claim basis. The ability to assess potential exposure often improves as a claim develops, including judicial determinations of coverage issues. As a result, reserves are adjusted accordingly.

Estimating IBNR reserves for asbestos and environmental claims is difficult because of the delayed and inconsistent reporting patterns associated with these claims. In addition, there are significant uncertainties associated with estimating critical assumptions, such as average clean-up costs, third-party costs, potentially responsible party shares, allocation of damages, litigation and coverage costs, and potential state and federal legislative changes. Normal historically-based actuarial approaches cannot be applied to asbestos and environmental claims because past loss history is not indicative of future potential loss emergence. In addition, while certain alternative models can be applied, such models can produce significantly different results with small changes in assumptions. As a result, we do not calculate an asbestos and environmental loss range. Historically, our asbestos and environmental claims have been significantly lower in volume, with less volatility and uncertainty than many of our competitors in the commercial lines industry. Prior to the introduction of the absolute pollution exclusion endorsement in the mid-1980's, we were primarily a personal lines carrier and therefore do not have broad exposure to asbestos and environmental claims. Additionally, we are the primary insurance carrier on the majority of these exposures, which provides more certainty in our reserve position compared to others in the insurance marketplace.

Pension and Post-retirement Benefit Plan Actuarial Assumptions

Our pension and post-retirement benefit obligations and related costs are calculated using actuarial methods, within the framework of U.S. GAAP. Two key assumptions, the discount rate and the expected return on plan assets, are important elements of expense and/or liability measurement. We evaluate these key assumptions annually. Other assumptions involve demographic factors, such as retirement age and mortality.

The discount rate enables us to state expected future cash flows at their present value on the measurement date. The purpose of the discount rate is to determine the interest rates inherent in the price at which pension benefits could be effectively settled. Our discount rate selection is based on high-quality, long-term corporate bonds. A higher discount rate reduces the present value of benefit obligations and generally reduces pension expense. Conversely, a lower discount rate increases the present

value of benefit obligations and generally increases pension expense. For additional information regarding our discount rate selection, refer to Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

The expected long-term rate of return on the plan assets is determined by considering the current and expected asset allocation, as well as historical and expected returns on each plan asset class. A lower expected rate of return on pension plan assets would increase pension expense. Our long-term expected return on plan assets decreased 13 basis points, to 6.24%, in 2016 as compared to 6.37% in 2015, reflecting the current interest rate environment.

At December 31, 2016, our pension and post-retirement benefit plan obligation was $346.0 million compared to $324.8 million at December 31, 2015. Plan assets were $316.5 million and $249.7 million at December 31, 2016 and December 31, 2015, respectively. Volatility in the marketplace, coupled with changes in the discount rate assumption, could materially impact our pension and post-retirement life valuation in the future. For additional information regarding our pension and post-retirement benefit plan obligations, see Note 14. “Retirement Plans” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Investment Valuation and OTTI

Investment Valuation

Fair value of our investment portfolio is defined under accounting guidance as the exit price or the amount that would be: (i) received to sell an asset; or (ii) paid to transfer a liability in an orderly transaction between market participants. When determining an exit price we must, when available, rely upon observable market data. Our AFS portfolio is carried at fair value and the related unrealized gains or losses are reflected in stockholders' equity, net of tax. For both our AFS and HTM portfolios, fair value is a key factor in the evaluation of a security for OTTI.

We have categorized our investment portfolio, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The fair value of approximately 99% of our investment portfolio is classified as either Level 1 or Level 2 in the fair value hierarchy. Fair value measurements in Level 1 represent quoted prices in active markets for identical assets. Fair value measurements in Level 2 represent prices determined using observable data from similar securities that have traded in the marketplace, typically using matrix pricing. The fair value of our Level 2 securities are determined by external pricing services. We have evaluated the pricing methodology used for these Level 2 prices and have determined that the inputs used are observable. For additional information regarding the valuation techniques used, refer to item (e) of Note 2. "Summary of Significant Accounting Policies" within Item 8. "Financial Statements and Supplementary Data." of this Annual Report.

Less than 1% of our investment portfolio is classified as Level 3 in the fair value hierarchy. Fair value measurements in Level 3 are based on unobservable market inputs because the related securities are not traded on a public market. For additional information regarding the valuation techniques used for our Level 3 securities, refer to item (e) of Note 2. "Summary of Significant Accounting Policies" within Item 8. "Financial Statements and Supplementary Data." of this Annual Report.

OTTI

Our investment portfolio is subject to market declines below amortized cost that may be other than temporary and therefore may result in the recognition of OTTI losses. Factors considered in the determination of whether or not a decline is other than temporary require significant judgment and include, but are not limited to, the financial condition of the issuer, the expected near-term and long-term prospects of the issuer, and our evaluation of the projected cash flow stream from the security. For additional information regarding our OTTI process and OTTI charges recorded, see item (d) of Note 2. "Summary of Significant Accounting Policies" and item (j) of Note 5. "Investments" within Item 8. "Financial Statements and Supplementary Data." of this Annual Report, respectively.

Reinsurance

Reinsurance recoverables on paid and unpaid losses and loss expenses represent estimates of the portion of such liabilities that will be recovered from reinsurers. Each reinsurance contract is analyzed to ensure that the transfer of risk exists to properly record the transactions in the Financial Statements. Amounts recovered from reinsurers are recognized as assets at the same time and in a manner consistent with the paid and unpaid losses associated with the reinsured policies. An allowance for estimated uncollectible reinsurance is recorded based on an evaluation of balances due from reinsurers and other available information. This allowance totaled $5.5 million at December 31, 2016 and $5.7 million at December 31, 2015. We continually monitor developments that may impact recoverability from our reinsurers and have available to us contractually provided remedies if necessary. For further information regarding reinsurance, see the “Reinsurance” section below and Note 8. “Reinsurance” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

We generated excellent financial results in 2016, continuing the trend of excellent financial performance we achieved in 2015 and 2014, which reflects our hard work to drive renewal pure price increases within our Standard Commercial and Personal Lines segments as well as our E&S segment, generate new business, improve the underlying profitability of our book of business through various underwriting and claims initiatives. In 2016, we also moved to more actively manage our investment portfolio to generate higher after-tax net investment income in an investment environment of declining interest rates. Our NPW growth of 8% in 2016 and 10% in 2015 was driven by our strong franchise value with our ivy league distribution partners. Over the past 28 quarters, our Standard Commercial Lines renewal pure price increases have cumulatively outperformed the Willis Towers Watson Commercial Lines Pricing (or CLIPs) survey by approximately 1700 basis points, while maintaining high retention rates. In addition, NPW growth was aided by the appointment of 110 retail agents in 2016 and some new business opportunities in our E&S segment as we increased our appetite for new business through our brokerage channel.

In addition to the cumulative pure renewal price increases we have achieved over the past several years, we have benefited from underwriting and claims process enhancements, as well as a shift in our business mix towards higher quality accounts. For example, our workers compensation book of business, which represents approximately 20% of our Standard Commercial Lines business, continues to benefit from the steps we have taken in recent years to increase premium rates and to improve the business mix by shifting towards lower hazard and smaller accounts from higher hazard and larger accounts. Additionally, claims initiatives, such as having an increased focus on reducing workers compensation medical costs through more favorable PPO contracts and greater PPO penetration, have helped to improve profitability of this line. The statutory combined ratios for this line of business improved, aided by net favorable loss development, from 110.1% in 2014 to 88.2% in 2015 and 80.7% in 2016. Our E&S segment has also seen an improvement in underwriting results as we have continued to deploy our corporate claims practices in this operation, although we have not yet met our financial targets for this segment. For a full discussion of the claims initiatives that we have deployed, refer to the “Reserves for Loss and Loss Expenses” section within Critical Accounting Policies in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Pre-tax net investment income grew 8% in 2016 compared to 2015 after decreasing 13% compared to 2014. The improvement in 2016 was driven by a higher fixed income asset base and improved returns on our alternative investments, while the decrease in 2015 compared to 2014 was due to lower returns on these alternative investments. During 2016, we determined that a more active management approach to our investment portfolio was necessary to maximize the risk-adjusted after-tax income and total return of the portfolio, while maintaining a similar level of credit quality and duration risk. We evaluated our previous buy-and-hold low turnover approach in the context of the current market environment, and concluded that a change was necessary to more effectively diversify, navigate, and manage the portfolio in response to the persistently low and volatile interest rate environment, the potential for rising inflation, and an uncertain political and tax landscape. To execute on this approach, we hired four new fixed income investment managers in 2016, increased our long-term target risk asset allocation, and modestly increased our exposure to non-investment grade fixed income securities, private equity investments, and private credit strategies to further diversity our allocation within risk assets. Our risk assets, which include public equities, non-investment grade fixed income securities, private equity investments, and other limited partnership private investments, represented 7% of our total invested assets at December 31, 2016 and may increase to approximately 10% over time.

The improvements to our underwriting profitability and after tax net investment income discussed above drove our long-term goal of generating an operating ROE that is approximately 300 basis points in excess of our weighted average cost of capital over time. Although our operating income increased in 2016, compared to 2015, our operating ROE was below 2015 levels, due to higher comprehensive income, partially offset by dividends paid to our shareholders, which has increased our shareholders' equity. Our ROE and operating ROE contributions by component are as follows:



Return on Average Equity	2016		2015		2014
Insurance segments	6.7	%	7.3		4.2
Investment income	6.7		7.0		8.6

Insurance Segments

The key metric in understanding our insurance segments’ contribution to ROE is the GAAP combined ratio. The following table provides a quantitative foundation for analyzing this ratio:

Fluctuations in our GAAP combined ratio were driven by the following:

•

Growth in our net premiums earned, which was driven by the acquisition of new business as well as renewal pure price increases on our standard lines business of 2.9% in 2016, 3.5% in 2015, and 5.8% in 2014. The renewal pure price increases provided earned rate of approximately 3.1% in 2016 and 4.0% in 2015, both of which were above our rate of expected claim inflation and thus contributed to improved combined ratios in each of the three years presented. However, as described below, our combined ratios are also significantly impacted by prior year casualty reserve development, net catastrophe loss activity, and non-catastrophe property losses.


•	Net favorable prior year casualty reserve development, the details of which are below:

2015	265.4		13.3		(2.2	)
2014	287.5		15.5		2.4

The improvement in the loss and loss expense ratio of 0.3 points, to 57.4% in 2016 from 57.7% in 2015 was offset by increases in the underwriting expense ratio of 0.8 points in 2016. The higher expense ratio was driven by 0.7 points of higher supplemental commission expense to our distribution partners as a result of improved underwriting profitability, as well as increased compensation paid to our employees, partially offset by reduced pension costs driven in part by the curtailment of our pension plan in the first quarter of 2016.

The 1.5-point increase in the 2015 underwriting expense ratio compared to 2014 was driven by the following:


•	Improved underwriting profitability that resulted in higher supplemental commission expense to our distribution partners and increased the ratio by 0.3 points;


•	Improved underwriting profitability that also resulted in higher annual incentive compensation expense to

employees and increased the ratio by 0.3 points;


•	Pension expense increases due to the accrual of service costs for eligible employees and the negative impact of

declining interest rates in 2014 that increased the ratio by 0.3 points; and

•

The March 2014 sale of the renewal rights to our $37 million Self Insured Group ("SIG") book of business that contributed $8 million to other income and reduced the combined ratio by 0.4 points. Although we did not solicit buyers, we decided to sell this small and specialized book of business when the opportunity presented itself because it had significant production outside of our standard lines footprint, and proved difficult to grow. We however, have retained our substantial individual risk public entity book of business and continue to look for opportunities to grow it.

Investments Segment

The ROE contribution from investment income has decreased from 2014 through 2016 reflecting declining investment leverage as a result of overall stockholders' equity growth outpacing investment income growth. This was, in part, due to strong profitability in our insurance operations coupled with declining portfolio yields.

Net realized gains/losses, which is another component of our investment segments' results, experienced volatility in its contribution to ROE in 2014 through 2016. For qualitative information regarding these fluctuations, which include OTTI charges and investment sales that are largely discretionary as to timing, refer to Note 5. "Investments" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Other

The ROE contribution from "other" above in the "Return on Average Equity" table, remained consistent from 2014 through 2016. However, we have restructured our long-term incentive program, which is included in other expenses, and expect these expenses to decrease by approximately $10 million over the next twelve months.

Outlook

In 2016, we delivered on an aggressive plan built on a profitable foundation that outperformed the estimated industry statutory combined ratio by approximately nine points. According to A.M. Best's Review and Preview dated January 26, 2017, the industry's 2016 overall statutory combined ratio is expected to be 100.7%, with commercial lines and personal lines expected to deliver a combined ratio of about 98.2% and 102.6%, respectively. We were able to achieve our results in a weakening commercial lines pricing market. Our renewal pure price increases averaged 2.6% during 2016 reflecting our strong agency relationships and pricing sophistication. As reported by the Willis Towers Watson Commercial Lines Insurance Pricing (or CLIPs) Survey, renewal rates for the industry in commercial lines were only up an average of 0.4% in the first nine months of 2016.

Our results for the year reflect the various initiatives we have implemented to maintain strong profitability while executing our strategic initiatives around growing the business. We continue to invest in technology to enhance the ease of doing business for our agents, the overall customer experience, and our data and analytics platforms. We believe these will be key strategic imperatives as we look to the future.

In 2017, we expect we will continue to focus on seeking out additional growth opportunities in our insurance operations while working towards our profit targets. We have been able to achieve NPW growth that has significantly exceeded the industry’s growth rate, while at the same time generating solid underwriting margins. In 2016, our Standard Commercial Lines experienced NPW growth of 9%, which was significantly above the A.M. Best expected industry growth rate for commercial lines. In addition, we have about a 1% market share in the 22 states in which we operate and our long-term goal is to increase our market share to approximately 3%. As we continue to leverage our agency franchise model by offering our distribution partners superior technology solutions and customer experience, we are targeting a 12% share of the business within our agencies, from our current 7% share, which we refer to as our "share of wallet." We are also seeking to increase our agency appointments over time to represent a 25% market share of the states in which we are fully operational, from our current 17% share. We believe our relationships with our distribution partners are among the strongest in the industry and underpin our success. During 2016, we appointed 110 new agents and we are planning for an additional 85 agency appointments in 2017.

Our plans are well on track to expand into Arizona and New Hampshire by the latter half of 2017. We have identified most of the agents that we will look to designate in those new markets. Our approach to entering new states is consistent with our agent franchise business model, which is predicated around our field based underwriting, claims, and customer service.

Turning to investments, we generated after-tax net investment income of $98.4 million, compared to $93.8 million in 2015 and 2% below our February 4, 2016 guidance of $100.0 million. Our challenge in 2017 will be navigating the increased market volatility that may accompany uncertainty regarding fiscal and monetary policy changes. For instance, the potential impact of limiting or eliminating tax-advantaged municipal bond interest may be significant to the returns of our municipal bond portfolio. Likewise, a reduction in the corporate tax rate, a border-adjustment tax, and repealing or replacing the ACA may have significant repercussions in the marketplace. Weighing these risks when seeking new opportunities, and managing the risks for existing positions and sectors in the portfolio, will be a key focus in the upcoming year.

In summary, we are positioning ourselves for a more competitive environment with a focus on generating adequate returns for our shareholders. We are preparing ourselves for changes in a period of heightened uncertainty surrounding interest rates, tax law changes, legislative changes, and inflation. We also have a number of internal strategic initiatives in place to enhance our technological offerings to our agents while improving the overall customer experience.

For 2017, based on our current view of the marketplace and assuming no tax law changes, we currently expect the following:


•	A statutory combined ratio, excluding catastrophe losses, of approximately 90.5%. This assumes no prior year casualty reserve development;


•	Catastrophe losses of 3.5 points;


•	After-tax investment income of approximately $110 million; and


•	Weighted average shares of approximately 59.2 million.

Our continued ability to obtain renewal pure price increases while balancing retention in this segment of our business has driven the NPW growth from 2014 through 2016 in the table above. Additionally, new business growth, especially in 2015 when compared to 2014, has also contributed to the NPW increases. Quantitative information on these drivers is as follows:

Retention	83		%	83	82
Renewal pure price increases on NPW	2.6			3.0	5.6
Direct new business	$	357.6		339.6	268.7

The GAAP loss and loss expense ratio increased 1.2 points in 2016 compared to 2015 due to net favorable prior year casualty reserve development of 4.7 points in 2016 compared to 5.3 points in 2015. Additionally, higher non-catastrophe property losses contributed to the increase in the loss and loss expense ratio. For quantitative information on this development by line of business, see "Financial Highlights of Results for Years Ended December 2016, 2015, and 2014" above and for qualitative information about the significant drivers of this development, see the line of business discussions below.

The GAAP loss and loss expense ratio decreased 7.9 points in 2015 compared to 2014 primarily due to the following: (i) earned rate above our expected claim inflation, which improved profitability by approximately 0.5 points for 2015; (ii) a 3.1-point decrease in property losses; (iii) net favorable prior year casualty reserve development of 5.3 points in 2015 compared to 3.2 points in 2014; and (iv) a decrease in the current year loss reserve estimate of 1.8 points in 2015 compared to 2014.

In addition to the increase in GAAP loss and loss expense ratio in 2016, there was an increase of 1.0 point in the GAAP underwriting expense ratio in 2016 compared to 2015. This increase was primarily attributable to higher supplemental commission expense to our distribution partners of 0.9 points.

The statutory underwriting expense ratio remained relatively flat in 2016 compared to 2015. The difference to GAAP is primarily due to higher supplemental commission expenses in the fourth quarter of 2015 that were immediately recognized on a statutory basis but earned in the GAAP underwriting expense ratio during 2016.

The 1.4-point increase in the GAAP underwriting expense ratio in 2015 compared to 2014 was primarily attributable to: (i) higher supplemental commission expense to our distribution partners of 0.4 points; (ii) increases in annual incentive compensation expense to employees of 0.2 points; and (iii) pension expense increases of 0.3 points. Additionally, the 2014 underwriting ratio included $8.0 million, or 0.6 points, of non-recurring benefit related to the sale of the renewal rights to our SIG book of business in March 2014.

The following is a discussion of our most significant Standard Commercial Lines of business:

Growth in 2016 and 2015 premium was primarily due to direct new business increases as outlined in the table above. Both reporting periods also had positive improvements in NPW and NPE from strong retention and improved renewal pure price increases.

The fluctuations in the statutory combined ratios were driven by changes in prior year development. Prior year development can be volatile year to year, requiring a longer period of time before true trends are fully recognized. The impact of the prior year casualty reserve development on this line was as follows:


•	2016: favorable prior year development of 8.5 points attributable to accident years 2008 through 2013 and 2015. This was primarily driven by lower than anticipated claims severities.


•	2015: favorable prior year development of 10.6 points attributable to accident years 2013 and prior. This was primarily driven by severities that continued to develop lower than expected, within both the premises and operations and products liability coverages. In addition, the reduction in frequencies exhibited in recent accident years continued into accident year 2015.


•	2014: favorable prior year development of 9.9 points driven by lower severities in the 2010 through 2012 accident years, within both the premises and operations and products liability coverages. In addition, accident years 2011 and 2012 continued to show lower claim counts, even as they matured.

In 2016, new business was up 9% over last year, while in 2015, new business was up 23% from 2014. In addition, renewal pure price increases and strong retention contributed to NPW growth in both periods. NPE increases in 2016 and 2015 were consistent with the fluctuations in NPW for their respective twelve-month periods ended December 31.

The 7.4-point increase in the statutory combined ratio in 2016 compared to 2015 was driven by: (i) unfavorable prior year casualty reserve development that increased the combined ratio by 5.5 points compared to last year; (ii) an increase in the current year loss reserve estimate of 2.1 points driven by an increase in casualty claim frequency; and (iii) higher property losses of 1.0 point.

The 5.7-point increase in the statutory combined ratio in 2015 compared to 2014 was driven by: (i) higher current year loss costs of 3.2 points driven by an increase in casualty claim frequency; (ii) prior year casualty reserve development that increased the combined ratio by 2.0 points compared to 2014; and (iii) higher property losses of 1.2 points.

In all three years, the combined ratio was positively impacted by earned rate that exceeded our expected claim inflation.

Property losses are outlined below:

2014	45.6		13.7		1.6		0.5		14.2	(0.5	)

Prior year casualty reserve development was as follows:


•	2016: Unfavorable development of 6.3 points, which was driven primarily by bodily injury liability for accident years 2014 and 2015. The unfavorable development in accident year 2014 was driven by higher than expected severity, whereas accident year 2015 was driven by higher than expected frequency and severity.


•	2015: Unfavorable development of 0.8 points, which was driven by bodily injury liability for accident years 2013 and 2014. This was partially offset by favorable development in accident years 2010 and 2011. The unfavorable development in accident years 2013 and 2014 was driven by severities that were greater than expected.


•	2014: Favorable development of 1.2 points driven by bodily injury liability for accident years 2012 and prior, partially offset by accident year 2013 due to higher frequency of claims.

NPW increases in both periods were due to: (i) renewal pure price increases; and (ii) increased retention. The NPW increases in 2015 compared to 2014 were also driven by increases in direct new business.

NPE increases in 2016 and 2015 were consistent with the fluctuations in NPW for their respective twelve-month periods ended December 31.

The 7.5-point decrease in the statutory combined ratio in 2016 compared to 2015 was due primarily to the following:


•	Favorable prior year casualty reserve development of $56.0 million, or 18.2 points, compared $37.0 million and 12.8 points in 2015. The favorable development in both periods was attributable to virtually all prior accident years.

The 21.9-point decrease in the statutory combined ratio in 2015 compared to 2014 was due to the following:


•	Favorable prior year casualty reserve development of $37.0 million, or 12.8 points, attributable to virtually all prior accident years, compared to no development in 2014.


•	Lower expected loss costs for the current accident year that resulted in an improvement of 9.3-points in 2015, reflecting our ongoing focus on improving this competitive line of business through pricing and claims initiatives, as discussed further above.

Favorable prior year casualty reserve development for both years is primarily driven by continued decreasing severities in accident years 2014 and prior. We believe these claim outcome improvements are due, in part, to lower medical inflation than originally anticipated, as well as the various claims initiatives that we have implemented, including, but not limited to:


•	Centralization of workers compensations claims handling;


•	The implementation of a strategic case management unit for the handling of workers compensation claims with high exposure and/or significant escalation risk;


•	A more proactive case management in areas of medical, pharmaceutical, and physical therapy treatments.

NPE increases in 2016 and 2015 were consistent with the fluctuations in NPW for their respective twelve-month periods ended December 31.

The fluctuation in the statutory combined ratios over the three-year period for this line were due to fluctuations in non-catastrophe property losses and catastrophe losses. Quantitative information regarding these items is as follows:

NPE decreases over the three-year period were consistent with the NPW fluctuations for their respective twelve-month periods ended December 31.

The GAAP loss and loss expense ratio decreased 6.2 points in 2016 compared to 2015, primarily driven by: (i) property losses that were lower than 2015 by 5.9 points; (ii) earned rate above our expected claim inflation, which improved profitability by approximately 1.3 points for 2016; and (iii) increased flood claims handling fees of 1.0 point, mainly due to Louisiana flooding and Hurricane Matthew during the second half of 2016. These decreases were partially offset by unfavorable prior year casualty reserve development that was higher than 2015 by 1.6 points.

The GAAP loss and loss expense ratio increased 3.1 points in 2015 compared to 2014, primarily driven by: (i) favorable prior year casualty reserve development that was lower than 2014 by 2.2 points; and (ii) property losses that were higher than 2014 by 0.9 points.

NPE increases in 2016 and 2015 were consistent with the increases in NPW for their respective twelve-month periods ended December 31, 2016.

The GAAP loss and loss expense ratio decreased 4.2 points in 2016 compared to 2015, primarily due to lower unfavorable prior year casualty reserve development that decreased by 6.4 points compared to 2015. This decrease was partially offset by a 1.3-point increase in the current year loss costs.

The GAAP loss and loss expense ratio increased 10.3 points in 2015 compared to 2014, primarily due to the following: (i) unfavorable prior year casualty reserve development that increased by 5.2 points compared to 2014; (ii) a 2.9-point increase in the current year loss costs; and (iii) a 1.5-point increase in property losses.

Unfavorable prior year casualty reserve development for 2016 was $6 million, driven by accident year 2014. Unfavorable prior year casualty reserve development for 2015 was $16 million. In 2015, we integrated the E&S claims operation with our Corporate Claims operation. As part of that effort, we completed a review of all complex claims. As a result, we recorded adverse prior year casualty reserve development of $10 million in the fourth quarter of 2015, bringing the full year adverse prior year development to $16 million. We also recorded a $5 million adjustment to the 2015 current accident year.

The GAAP underwriting expense ratio decreased 2.2 points in 2016 compared to 2015, primarily due to the following: (i) a 1.6-point reduction from the annual cash incentive plan payment for employees in this segment based on 2015 underwriting results; and (ii) 0.5-point decrease from lower supplemental commission expense to our distribution partners.

Our E&S business is comprised of risks that are similar in nature to our Standard Commercial Lines, with smaller-sized insureds and lower policy limits. Approximately 98% of the policies in this segment have limits of less than $1 million. We will continue to deploy our Corporate Claims practices into the E&S operation in 2017, including the use of more robust monitoring tools. We believe these actions will allow us to better assess the associated liability for these claims and will ultimately result in improved outcomes. For more information, refer to the E&S Lines discussion within the Reserves for Losses and Loss Expenses section of "Critical Accounting Policies and Estimates" in this MD&A.

Reinsurance

We use reinsurance to protect our capital resources and insure us against losses on property and casualty risks that we underwrite. We use two main reinsurance vehicles: (i) a reinsurance pooling agreement among our Insurance Subsidiaries in which each company agrees to share in premiums and losses based on certain specified percentages; and (ii) reinsurance contracts and arrangements with third parties that cover various policies that we issue to our customers.

Reinsurance Pooling Agreement

The primary purposes of the reinsurance pooling agreement among our Insurance Subsidiaries are the following:


•	Pool or share proportionately the underwriting profit and loss results of property and casualty insurance underwriting operations through reinsurance;


•	Prevent any of our Insurance Subsidiaries from suffering undue loss;


•	Reduce administration expenses; and


•	Permit all of the Insurance Subsidiaries to obtain a uniform rating from A.M. Best.

The following illustrates the pooling percentages by Insurance Subsidiary as of December 31, 2016:



Insurance Subsidiary		Pooling Percentage
Selective Insurance Company of America ("SICA")		32.0%
Selective Way Insurance Company ("SWIC")		21.0%
Selective Insurance Company of South Carolina ("SICSC")		9.0%
Selective Insurance Company of the Southeast ("SICSE")		7.0%
Selective Insurance Company of New York ("SICNY")		7.0%
Selective Casualty Insurance Company ("SCIC")		7.0%
Selective Auto Insurance Company of New Jersey ("SAICNJ")		6.0%
Mesa Underwriters Specialty Insurance Company ("MUSIC")		5.0%
Selective Insurance Company of New England ("SICNE")		3.0%
Selective Fire and Casualty Insurance Company ("SFCIC")		3.0%

Reinsurance Treaties and Arrangements

By entering into reinsurance treaties and arrangements, we are able to increase underwriting capacity and accept larger risks and a larger number of risks without directly increasing capital or surplus. Our reinsurance consists of traditional reinsurance and we do not purchase finite reinsurance. Under our reinsurance treaties, the reinsurer generally assumes a portion of the losses we cede to them in exchange for a portion of the premium. Amounts not reinsured are known as retention. Reinsurance does not legally discharge us from liability under the terms and limits of our policies, but it does make our reinsurer liable to us for the amount of liability we cede to them. Accordingly, we have counterparty credit risk from our reinsurers. We attempt to mitigate this credit risk by: (i) pursuing relationships with reinsurers rated “A-” or higher; or (ii) obtaining collateral to secure reinsurance obligations. Some of our reinsurance contracts include provisions that permit us to terminate or commute the reinsurance treaty if the reinsurer's financial condition or rating deteriorates. We monitor the financial condition of our reinsurers and we review the quality of reinsurance recoverables and reserves for uncollectible reinsurance. For additional information regarding our counterparty credit risk with our reinsurers, see Note 8. "Reinsurance" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

We have reinsurance contracts that separately cover our property and casualty insurance business. Available reinsurance can be segregated into the following key categories:


•	Property Reinsurance - includes our property excess of loss treaties purchased for protection against large individual property losses and our property catastrophe treaties purchased to provide protection for the overall property portfolio against severe catastrophic events. Facultative reinsurance is used for property risks that are in excess of our treaty capacity.


•	Casualty Reinsurance - purchased to provide protection for both individual large casualty losses and catastrophic casualty losses involving multiple claimants or customers. Facultative reinsurance is also used for casualty risks that are in excess of our treaty capacity.


•	Terrorism Reinsurance - in addition to protection built into our property and casualty reinsurance treaties, terrorism protection is available as a federal backstop related to terrorism losses as provided under the Terrorism Risk Insurance Program Reauthorization Act (“TRIPRA”). For further information regarding this legislation, see Item 1A. “Risk Factors.” of this Form 10-K.


•	Flood Reinsurance - as a servicing carrier in the WYO Program, we receive a fee for writing flood business, for which the related premiums and losses are 100% ceded to the federal government.

In addition to the above categories, we have entered into several reinsurance agreements with Montpelier Re Insurance Ltd. as part of the acquisition of MUSIC. Together, these agreements provide protection for losses on policies written prior to the December 2011 acquisition and any development on reserves established by MUSIC as of the date of acquisition. The reinsurance recoverables under these treaties are collateralized.

Property Reinsurance

The property catastrophe treaty, which covers both our standard market and E&S business, was renewed effective January 1, 2017. The current treaty structure remains the same, providing total coverage of $685 million in excess of $40 million. The annual aggregate limit net of our co-participation is approximately $1.0 billion for 2017. We also renewed the separate catastrophe treaty of $35 million in excess of $5 million that covers events outside of our standard lines footprint, in support of our growing E&S property book. We expect the overall catastrophe ceded premium for 2017 to be similar to 2016, although down modestly on a risk-adjusted basis. As our need for catastrophe reinsurance increases, we seek ways to minimize credit risk inherent in a reinsurance transaction by dealing with highly-rated reinsurance partners and purchasing collateralized reinsurance products, particularly for high severity, low-probability events. The current reinsurance program includes $201 million in collateralized limit, primarily in the top layer of the catastrophe program.

We continue to assess our property catastrophe exposure aggregations, modeled results, and effects of growth on our property portfolio, and strive to manage our exposure to individual large events balanced against the cost of reinsurance protections.

Although we model various catastrophic perils, due to our geographic spread, the risk of hurricane continues to be the most significant natural catastrophe peril to which our portfolio is exposed. Below is a summary of the largest five actual hurricane losses that we experienced in the past 25 years:



($ in millions)	Actual Gross Loss	Net Loss²	Accident Year
Hurricane Name	Actual Gross Loss	Net Loss²	Accident Year
Superstorm Sandy	125.4 ¹	45.5	2012
Hurricane Irene	44.8	40.2	2011
Hurricane Hugo	26.4	3.0	1989
Hurricane Isabel	25.1	15.7	2003
Hurricane Floyd	14.5	14.5	1999

¹ This amount represents reported and unreported gross losses estimated as of December 31, 2016.

²Net loss does not include reinstatement premiums, taxes, or flood claims handling fees.

We use the results of the Risk Management Solutions and AIR Worldwide models in our review of exposure to hurricane risk. Each of these third party vendors provide two views of the modeled results as follows: (i) a long-term view that closely relates modeled event frequency to historical hurricane activity; and (ii) a medium-term view that adjusts historical frequencies to reflect higher expectations of hurricane activity in the North Atlantic Basin. We believe that modeled estimates provide a range of potential outcomes and we review multiple estimates for purposes of understanding our catastrophic risk. The following

table provides modeled hurricane results based on a blended view of the four models for the Insurance Subsidiaries' combined property book as of July 2016:



Occurrence Exceedence Probability	Four-Model Blend
($ in thousands)	Gross Losses	Net Losses¹	Net Losses as a Percent of Equity²
4.0% (1 in 25 year event)	$124,207	29,215	2%
2.0% (1 in 50 year event)	224,781	31,598	2
1.0% (1 in 100 year event)	386,755	37,091	2
0.67% (1 in 150 year event)	515,584	41,964	3
0.5% (1 in 200 year event)	631,404	47,636	3
0.4% (1 in 250 year event)	704,793	52,893	3
0.2% (1 in 500 year event)	1,029,687	251,137	16

¹ Losses are after tax and include applicable reinstatement premium.

² Equity as of December 31, 2016.

Our current catastrophe reinsurance program exhausts at a 1 in 265 year return period, or events with 0.38% probability, based on a multi-model view of hurricane risk. Our actual gross and net losses incurred from U.S. landfalling hurricanes will vary, perhaps materially, from our estimated modeled losses.

The property excess of loss treaty, which covers both our standard market and E&S business, was renewed on July 1, 2016 with an additional layer also renewed on January 1, 2017. The major terms of these treaties are consistent with the prior year. The details of the current year treaty are included in the table below.

The following is a summary of our property reinsurance treaties and arrangements covering our Insurance Subsidiaries:



PROPERTY REINSURANCE ON INSURANCE PRODUCTS
Treaty Name	Reinsurance Coverage	Terrorism Coverage
Property Catastrophe Excess of Loss (covers all insurance segments)	$685 million above $40 million retention in four layers:	All nuclear, biological, chemical, and radioactive ("NBCR") losses are excluded regardless of whether or not they are certified under TRIPRA. Non-NBCR losses are covered to the same extent as non-terrorism losses. Please see Item 1A. “Risk Factors.” of this Form 10-K for discussion regarding TRIPRA.
	- 80% of losses in excess of $40 million up to $100 million;
	- 95% of losses in excess of $100 million up to $225 million;
	- 95% of losses in excess of $225 million up to $475 million; and
	- 90% of losses in excess of $475 million up to $725 million.
	- The treaty provides one reinstatement per layer for the first three layers and no reinstatements on the fourth layer. The annual aggregate limit is $1.0 billion, net of the Insurance Subsidiaries' co-participation.

Property Excess of Loss (covers all insurance segments)	$58 million above $2 million retention covering 100% in three layers. Losses other than TRIPRA certified losses are subject to the following reinstatements and annual aggregate limits:	All NBCR losses are excluded regardless of whether or not they are certified under TRIPRA. For non-NBCR losses, the treaty distinguishes between acts committed on behalf of foreign persons or foreign interests ("Foreign Terrorism") and those that are not. The treaty provides annual aggregate limits for Foreign Terrorism (other than NBCR) acts of $24 million for the first layer and $60 million for the second layer and for the third layer approximately $36 million in annual aggregate limits. Non-foreign terrorism losses (other than NBCR) are covered to the same extent as non-terrorism losses.
	- $8 million in excess of $2 million layer provides unlimited reinstatements;
	- $30 million in excess of $10 million layer provides three reinstatements, $120 million in aggregate limits; and
	- $20 million in excess of $40 million layer provides approximately $76 million in aggregate limits.

Flood	100% reinsurance by the federal government’s WYO Program.	None

Casualty Reinsurance

The casualty excess of loss treaty, which covers both our standard market and E&S business, was renewed on July 1, 2016 and is effective through June 30, 2017, with substantially the same terms as the expiring treaty. The details of the current year treaty are included in the table below.

The following is a summary of our casualty reinsurance treaties and arrangements covering our Insurance Subsidiaries:



CASUALTY REINSURANCE ON INSURANCE PRODUCTS
Treaty Name	Reinsurance Coverage	Terrorism Coverage
Casualty Excess of Loss (covers all insurance segments)	There are six layers covering 100% of $88 million in excess of $2 million. Losses other than terrorism losses are subject to the following reinstatements and annual aggregate limits:	All NBCR losses are excluded. All other losses stemming from the acts of terrorism are subject to the following reinstatements and annual aggregate limits:
	- $3 million in excess of $2 million layer with $72 million annual aggregate limit;	- $3 million in excess of $2 million layer with $15 million net annual terrorism aggregate limit;
	- $7 million in excess of $5 million layer with $35 million annual aggregate limit;	- $7 million in excess of $5 million layer with $28 million net annual terrorism aggregate limit;
	- $9 million in excess of $12 million layer with $27 million annual aggregate limit;	- $9 million in excess of $12 million layer with $27 million net annual terrorism aggregate limit;
	- $9 million in excess of $21 million layer with $18 million annual aggregate limit;	- $9 million in excess of $21 million layer with $18 million net annual terrorism aggregate limit;
	- $20 million in excess of $30 million layer with $40 million annual aggregate limit;	- $20 million in excess of $30 million layer with $40 million net annual terrorism aggregate limit;
	- $40 million in excess of $50 million layer with $80 million annual aggregate limit;	- $40 million in excess of $50 million layer with $80 million net annual terrorism aggregate limit;

Montpelier Re Quota Share and Loss Development Cover (covers E&S Lines)	As part of the acquisition of MUSIC we entered into several reinsurance agreements that together provide protection for losses on policies written prior to the acquisition and any development on reserves established by MUSIC as of the date of acquisition. The reinsurance recoverables under these treaties are 100% collateralized. Montpelier Re was acquired by Endurance Specialty on December 29, 2015.	Provides full terrorism coverage including NBCR.

We have other reinsurance treaties that we do not consider core to our reinsurance program, such as our Surety and Fidelity Excess of Loss Reinsurance Treaty, National Workers Compensation Reinsurance Pool Quota Share, which covers business assumed from the involuntary workers compensation pool, a property catastrophe excess of loss treaty covering losses outside of our standard lines footprint states, and our Equipment Breakdown Coverage Reinsurance Treaty.

We regularly reevaluate our overall reinsurance program and try to develop effective ways to manage transfer of risk. Our analysis is based on a comprehensive process that includes periodic analysis of modeling results, aggregation of exposures, exposure growth, diversification of risks, limits written, projected reinsurance costs, financial strength of reinsurers, and projected impact on earnings, equity, and statutory surplus. We strive to balance sometimes opposing considerations of reinsurer credit quality, price, terms, and our appetite for retaining a certain level of risk.

Investments

The primary objective of the investment portfolio is to maximize after-tax investment income while balancing risk and generating long-term growth in shareholder value. Our investment philosophy includes certain return and risk objectives for the fixed income, equity, and other investment portfolios. After-tax yield and income generation are key drivers to our investment strategy, which has historically been balanced with a long-term “buy-and-hold,” low turnover approach.

To execute on this revised approach, we hired several new investment managers who were on-boarded in the fourth quarter of 2016. We modestly increased our exposure to below investment grade fixed income securities, private equity, and private credit strategies to further diversity our allocation within risk assets, which principally includes public equities, high-yield fixed income securities, and private equity, in conjunction with repositioning the portfolio to a long-term target risk asset allocation of approximately 10% of total invested assets. While our approach to managing the investment portfolio has changed, our core investment philosophy has not changed. We remain focused on diversification, capital preservation, investment quality, and liquidity to meet our needs and obligations.

Total Invested Assets



($ in thousands)	2016		2015	Change
Total invested assets	$	5,364,947	5,089,269	5	%
Invested assets per dollar of stockholders' equity	3.50		3.64	(4	)
Unrealized gain – before tax	64,803		69,224	(6	)
Unrealized gain – after tax	42,122		44,996	(6	)

The increase in our investment portfolio at December 31, 2016 compared with year-end 2015 was primarily driven by operating cash flow of $301.8 million, partially offset by a decrease in unrealized gains of $4.4 million. The $4.4 million change in unrealized gains was comprised of a $12.6 million increase in unrealized gains in our equity portfolio offset by a decrease in unrealized gains in our fixed income securities portfolio of $17 million, which was driven by general interest rate movements as seen in the 10-year U.S. Treasury Note, which rose by 17 basis points in 2016.

We structure our portfolio conservatively with a focus on: (i) asset diversification; (ii) investment quality; (iii) liquidity, particularly to meet the cash obligations of our three insurance segments; (iv) consideration of taxes; and (v) preservation of capital. We believe that we have a high quality and liquid investment portfolio. The breakdown of our investment portfolio is as follows:



As of December 31,	2016		2015
Fixed income securities:
U.S. government obligations	2	%	2
Foreign government obligations	1		—
State and municipal obligations	27		30
Corporate securities¹	37		38
Mortgage-backed securities (“MBS”)	15		16
Collateralized loan obligations ("CLO") and other asset-backed securities ("ABS")	10		5
Total fixed income securities	92		91
Equity securities:
Common stock	2		4
Preferred stock¹	—		—
Total equity securities	2		4
Short-term investments	4		4
Other investments	2		1
Total	100	%	100

¹Included $68.2 million of preferred stock within corporate securities and $16.1 million of preferred stock within equity securities. In aggregate, these account for approximately 2% of invested assets at December 31, 2016.

Fixed Income Securities

The effective duration of the fixed income securities portfolio as of December 31, 2016 was 3.6 years, including short-term investments, compared to the Insurance Subsidiaries’ liability duration of approximately 4.0 years. The current duration of the fixed income securities portfolio is within our historical range, and is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. We maintain a well-diversified portfolio across sectors, credit quality, and maturities that affords us ample liquidity. Every purchase or sale is made with the intent of maximizing risk-adjusted investment returns in the current market environment while balancing capital preservation.

Our fixed income securities portfolio maintained a weighted average credit rating of AA- as of December 31, 2016 with 97% and 99% of the securities within the portfolio being investment grade quality at December 31, 2016 and December 31, 2015, respectively. For further details on how we manage overall credit quality and the various risks to which our portfolio is subject, see Item 7A. “Quantitative and Qualitative Disclosures About Market Risk.” of this Form 10-K.

Unrealized/Unrecognized Losses

Held-to-maturity ("HTM") fixed income securities were in an unrealized/unrecognized loss position of $0.2 million at December 31, 2016. Available-for-sale ("AFS") fixed income securities that were in an unrealized loss position at December 31, 2016 by contractual maturity are shown below. MBS are included in the maturity tables using the estimated average life of each security. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.



Contractual Maturities
($ in thousands)
Available-for-sale ("AFS") fixed income securities:	Amortized Cost		Fair Value	Unrealized Loss
One year or less	$	24,522	24,349	(173	)
Due after one year through five years	520,626		517,830	(2,796	)
Due after five years through ten years	740,795		730,764	(10,031	)
Due after ten years	85,752		83,355	(2,397	)
Total	$	1,371,695	1,356,298	(15,397	)

We have reviewed securities in an unrealized/unrecognized loss position in accordance with our OTTI policy as discussed previously in Note 2. "Summary of Significant Accounting Policies" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K. For qualitative information regarding our conclusions as to why these impairments are deemed temporary, see Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Net Investment Income

The components of net investment income earned were as follows:



($ in thousands)	2016			2015		2014
Fixed income securities	$	129,306		123,230		126,489
Equity securities	7,368			9,161		7,449
Short-term investments	686			112		66
Other investments	2,940			(1,890	)	13,580
Investment expenses	(9,546		)	(9,297	)	(8,876	)
Net investment income earned – before tax	130,754			121,316		138,708
Net investment income tax expense	32,349			27,480		34,501
Net investment income earned – after tax	$	98,405		93,836		104,207
Effective tax rate	24.7		%	22.7		24.9
Annual after-tax yield on fixed income securities	2.0			2.1		2.2
Annual after-tax yield on investment portfolio	1.9			1.9		2.2

The $9.4 million increase in investment income before tax in 2016, compared to 2015, was primarily attributable to increases in fixed income securities of $6.1 million and in other investment income of $4.8 million. Returns on fixed income securities increased due to a higher asset base of which 2016 fixed income securities reflected and increased allocation to taxable asset classes with a 3% reduction to the tax advantaged asset classes. Other investments increased due to improvement in our energy-related and private equity limited partnerships. The increase in net investment income after-tax attributable to our taxable fixed income securities and our other investments led to an overall increase in our effective tax rate of 200 basis points.

The $17.4 million decrease in investment income before tax in 2015, compared to 2014, was primarily attributable to a decrease in other investment income of $15.5 due to lower returns on the alternative investments within the other investments portfolio. In particular, our energy-related limited partnerships were negatively impacted by declining oil prices. Additionally, lower reinvestment yields on our fixed income securities portfolio continued to put pressure on investment income. In 2015, bonds that matured or were sold, valued at $735.6 million, had yields that averaged 3.3% pre-tax, while new purchases of $1.0 billion had an average pre-tax yield of 2.4%.

Realized Gains and Losses

Our general philosophy for sales of securities is to reduce our exposure to securities and sectors based on economic evaluations

and when the fundamentals for that security or sector have deteriorated, or to opportunistically trade out of securities to other

securities with better economic return characteristics. Net realized (losses)/gains for the indicated periods were as follows:



($ in thousands)	2016			2015		2014
Net realized gains, excluding OTTI	$	3,562		31,537		37,703
OTTI	(8,499		)	(18,366	)	(11,104	)
Total net realized (losses) gains	$	(4,937	)	13,171		26,599

We regularly review our entire investment portfolio for declines in fair value. If we believe that a decline in the value of a particular investment is other than temporary, we record it as an OTTI through realized losses in earnings for the credit-related portion and through unrealized losses in OCI for the non-credit related portion for fixed income securities. If there is a decline in fair value of an equity security that we do not intend to hold or if we determine the decline is other than temporary, we write down the cost of the investment to fair value and record the charge through earnings as a component of realized losses.

For a discussion of our realized gains and losses as well as our OTTI methodology, see Note 2. “Summary of Significant Accounting Policies” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K. In addition, for qualitative information regarding these charges, see Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Federal Income Taxes

The following table provides information regarding federal income taxes.



($ in millions)	2016			2015	2014
Federal income tax expense	$	61.5		66.8	55.3
Effective tax rate	27.9		%	28.7	28.1

The effective tax rate in the table above differs from the statutory tax rate of 35% primarily because of tax-advantaged interest and dividend income. The contribution of this tax-advantaged income to overall pre-tax income remained relatively stable in 2014 through 2016 and, as a result, there is not a significant variance in our overall effective tax rate during these periods.

We believe that our future effective tax rate will continue to be impacted by similar items, assuming no significant changes to tax laws. However, the U.S. federal income tax structure is currently under significant debate as a result of the recent Presidential election. We are unable to provide an estimate of the magnitude of potential changes. However, one impact, amongst the potential for many, would be if the corporate tax rate were to be reduced to a rate between 15% and 20%, this would result in a revaluation of our current deferred tax asset from approximately $85 million to approximately $36 million to $49 million, all else remaining equal.

For a reconciliation of our effective tax rate to the statutory rate of 35%, see Note 13. “Federal Income Taxes” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Financial Condition, Liquidity, and Capital Resources

Capital resources and liquidity reflect our ability to generate cash flows from business operations, borrow funds at competitive rates, and raise new capital to meet operating and growth needs.

Liquidity

We manage liquidity with a focus on generating sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. Our cash and short-term investment position of $222 million at December 31, 2016 was comprised of $18 million at Selective Insurance Group, Inc. (the “Parent”) and $204 million at the Insurance Subsidiaries. Short-term investments are generally maintained in "AAA" rated money market funds approved by the National Association of Insurance Commissioners ("NAIC"). The Parent maintains an investment portfolio containing high-quality, highly-liquid government and corporate fixed income securities. This portfolio amounted to $74 million at December 31, 2016, compared to $62 million at December 31, 2015.

Sources of Liquidity

Sources of cash for the Parent have historically consisted of dividends from the Insurance Subsidiaries, the investment portfolio discussed above, borrowings under lines of credit and loan agreements with certain Insurance Subsidiaries, and the issuance of stock and debt securities. We continue to monitor these sources, giving consideration to our long-term liquidity and capital preservation strategies.

Insurance Subsidiary Dividends

The Insurance Subsidiaries paid $61 million in dividends to the Parent in 2016. As of December 31, 2016, our allowable ordinary maximum dividend is $193 million for 2017.

Any dividends to the Parent are subject to the approval and/or review of the insurance regulators in the respective Insurance Subsidiaries' domiciliary states and are generally payable only from earned surplus as reported in the statutory annual statements of those subsidiaries as of the preceding December 31. Although past dividends have historically been met with regulatory approval, there is no assurance that future dividends that may be declared will be approved. For additional information regarding dividend restrictions, refer to Note 19. “Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds” in Item 8. “Financial Statements and Supplementary Data.” of this Form

10-K.

The Insurance Subsidiaries generate liquidity through insurance float, which is created by collecting premiums and earning investment income before losses are paid. The period of the float can extend over many years. Our investment portfolio consists of maturity dates that continually provide a source of cash flow for claims payments in the ordinary course of business. The effective duration of the fixed income securities portfolio, including short-term investments, was 3.6 years as of December 31, 2016, while the liabilities of the Insurance Subsidiaries have a duration of 4.0 years. As protection for the capital resources at the Insurance Subsidiaries, we purchase reinsurance coverage for any significantly large claims or catastrophes that may occur during the year.

Line of Credit

The Parent's line of credit with Wells Fargo Bank, National Association, as administrative agent, and Branch Banking and Trust Company (BB&T) (referred to as our "Line of Credit"), was renewed effective December 1, 2015 with a borrowing capacity of $30 million, which can be increased to $50 million with the approval of both lending partners. This Line of Credit expires on December 1, 2020 and has an interest rate which varies and is based on, among other factors, the Parent's debt ratings.

For information regarding the Line of Credit agreement and corresponding representations, warranties, and covenants, refer to Note 10. “Indebtedness” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Several of our Insurance Subsidiaries are members of certain branches of the Federal Home Loan Bank, which provides those subsidiaries with additional access to liquidity. Membership is as follows:



Branch				Insurance Subsidiary Member
Federal Home Loan Bank of Indianapolis ("FHLBI")				SICSC¹
				SICSE¹
Federal Home Loan Bank of New York ("FHLBNY")				SICA
				SICNY
¹These subsidiaries are jointly referred to as the "Indiana Subsidiaries" as they are domiciled in Indiana.

The Line of Credit permits aggregate borrowings from the FHLBI and the FHLBNY up to 10% of the respective member company’s admitted assets for the previous year. Additionally, the FHLBNY limits borrowings by SICA and SICNY to 5% of admitted assets for the previous year. All borrowings from both the FHLBI and the FHLBNY are required to be secured by investments pledged as collateral. For additional information regarding collateral outstanding, refer to Note 5. "Investments" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

The following table provides information on the remaining capacity for Federal Home Loan Bank borrowings based on these restrictions, as well as the amount of additional stock that would need to be purchased to allow these member companies to borrow their remaining capacity:



($ in millions)	Admitted Assets as of December 31, 2016		Borrowing Limitation		Amount Borrowed	Remaining Capacity	Additional Stock Requirements
As of December 31, 2016	Admitted Assets as of December 31, 2016		Borrowing Limitation		Amount Borrowed	Remaining Capacity	Additional Stock Requirements
SICSC	$	644.9	$	64.5	32.0	32.5	1.4
SICSE	490.7		49.1		28.0	21.1	0.9

SICNY	424.3		21.2		—	21.2	1.0
Total			$	250.5	110.0	140.5	6.3

Intercompany Loan Agreements

The Parent has lending agreements with the Indiana Subsidiaries that have been approved by the Indiana Department of Insurance, which provide additional liquidity to the Parent. Similar to the Line of Credit agreement, these lending agreements limit borrowings by the Parent from the Indiana Subsidiaries to 10% of the admitted assets of the respective Indiana Subsidiary. The following table provides information on the Parent’s borrowings and remaining borrowing capacity from the Indiana Subsidiaries:



($ in millions)	Admitted Assets as of December 31, 2016		Borrowing Limitation		Amount Borrowed	Remaining Capacity
As of December 31, 2016	Admitted Assets as of December 31, 2016		Borrowing Limitation		Amount Borrowed	Remaining Capacity
SICSC	$	644.9	$	64.5	27.0	37.5
SICSE	490.7		49.1		18.0	31.1
Total			$	113.6	45.0	68.6

Short-term Borrowings

There were no balances outstanding under the Line of Credit at December 31, 2016 or at any time during 2016. During 2016, SICA borrowed an aggregate of $105 million from the FHLBNY, of which $55 million has already matured and has been paid.

For additional information regarding other borrowings, see Note 10. "Indebtedness" in Item 8. "Financial Statements and Supplementary Data." of this Form 10-K.

Capital Market Activities

The Parent had no private or public issuances of stock or debt instruments during 2016.

Uses of Liquidity

The liquidity generated from the sources discussed above is used, among other things, to pay dividends to our shareholders. Dividends on shares of the Parent's common stock are declared and paid at the discretion of the Board of Directors based on our operating results, financial condition, capital requirements, contractual restrictions, and other relevant factors. In October 2016, our Board of Directors approved an increase in the quarterly cash dividend, to $0.16 from $0.15 per share.

Our ability to meet our interest and principal repayment obligations on our debt, as well as our ability to continue to pay dividends to our stockholders, is dependent on liquidity at the Parent coupled with the ability of the Insurance Subsidiaries to pay dividends, if necessary, and/or the availability of other sources of liquidity to the Parent. Our next two principal repayments, each in the amount of $25 million, are due in 2021, with the next following principal payment due in 2026.

Restrictions on the ability of the Insurance Subsidiaries to declare and pay dividends, without alternative liquidity options, could materially affect our ability to service debt and pay dividends on common stock.

Capital Resources

Capital resources provide protection for policyholders, furnish the financial strength to support the business of underwriting insurance risks, and facilitate continued business growth. At December 31, 2016, we had GAAP stockholders’ equity of $1.5 billion and statutory surplus of $1.6 billion. With total debt of $439 million, our debt-to-capital ratio was approximately 22%.

Our cash requirements include, but are not limited to, principal and interest payments on various notes payable, dividends to stockholders, payment of claims, payment of commitments under limited partnership agreements and capital expenditures, as

well as other operating expenses, which include commissions to our distribution partners, labor costs, premium taxes, general and administrative expenses, and income taxes. For further details regarding our cash requirements, refer to the section below entitled, “Contractual Obligations, Contingent Liabilities, and Commitments.”

We continually monitor our cash requirements and the amount of capital resources that we maintain at the holding company and operating subsidiary levels. As part of our long-term capital strategy, we strive to maintain capital metrics, relative to the macroeconomic environment, that support our targeted financial strength. Based on our analysis and market conditions, we may take a variety of actions, including, but not limited to, contributing capital to the Insurance Subsidiaries in our insurance segments, issuing additional debt and/or equity securities, repurchasing shares of the Parent’s common stock, and increasing stockholders’ dividends.

Our capital management strategy is intended to protect the interests of the policyholders of the Insurance Subsidiaries and our stockholders, while enhancing our financial strength and underwriting capacity.

Book value per share increased to $26.42 as of December 31, 2016, from $24.37 as of December 31, 2015, primarily due to $2.70 in net income, partially offset by $0.61 paid in dividends to our shareholders.

Off-Balance Sheet Arrangements

At December 31, 2016 and December 31, 2015, we did not have any material relationships with unconsolidated entities or financial partnerships, such entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. As such, we are not exposed to any material financing, liquidity, market, or credit risk that could arise if we had engaged in such relationships.

Contractual Obligations, Contingent Liabilities, and Commitments

As discussed in the “Reserves for Losses and Loss Expenses” section in the "Critical Accounting Policies and Estimates" section of this MD&A, we maintain case reserves and estimates of reserves for losses and loss expenses IBNR, in accordance with industry practice. Using generally accepted actuarial reserving techniques, we project our estimate of ultimate losses and loss expenses at each reporting date.

Given that the losses and loss expense reserves are estimates, as described in detail under the “Critical Accounting Policies and Estimates” section of this MD&A, the payment of actual losses and loss expenses is generally not fixed as to amount or timing. Due to this uncertainty, financial accounting standards prohibit us from discounting these reserves to their present value. Additionally, estimated losses as of the financial statement date do not consider the impact of estimated losses from future business. Therefore, the projected settlement of the reserves for net losses and loss expenses will differ, perhaps significantly, from actual future payments.

The projected paid amounts in the table below by year are estimates based on past experience, adjusted for the effects of current developments and anticipated trends, and include considerable judgment. There is no precise method for evaluating the impact of any specific factor on the projected timing of when loss and loss expense reserves will be paid and as a result, the timing and amounts of the actual payments will be affected by many factors. Care must be taken to avoid misinterpretation by those unfamiliar with this information or familiar with other data commonly reported by the insurance industry.

Our future cash payments associated with contractual obligations pursuant to operating and capital leases, debt, interest on debt obligations, and losses and loss expenses as of December 31, 2016 are summarized below:

See the “Short-term Borrowings” section above for a discussion of our syndicated Line of Credit agreement.

At December 31, 2016, we had contractual obligations that expire at various dates through 2030 that may require us to invest up to an additional $143.7 million in alternative and other investments. There is no certainty that any such additional investment will be required. We have issued no material guarantees on behalf of others and have no trading activities involving non-exchange traded contracts accounted for at fair value. We have no material transactions with related parties other than those disclosed in Note 16. “Related Party Transactions” included in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Ratings

We are rated by major rating agencies that issue opinions on our financial strength, operating performance, strategic position, and ability to meet policyholder obligations. We believe that our ability to write insurance business is most influenced by our rating from A.M. Best. In the third quarter of 2016, A.M. Best reaffirmed our rating of "A (Excellent)," their third highest of 13 financial strength ratings with a "stable" outlook. The rating reflects A.M. Best's view that we have an excellent level of risk-adjusted capitalization, targeted regional markets with strong distribution partner relationships, and consistently profitable operating performance. We have been rated "A" or higher by A.M. Best for the past 86 years. A downgrade from A.M. Best to a rating below “A-” is an event of default under our Line of Credit and could affect our ability to write new business with customers and/or distribution partners, some of whom are required (under various third-party agreements) to maintain insurance with a carrier that maintains a specified A.M. Best minimum rating.

Ratings by other major rating agencies are as follows:


•	Fitch Ratings ("Fitch") - Our "A+" Rating was reaffirmed in the third quarter of 2016 with a "stable"outlook by Fitch. In taking this action, Fitch cited our strong underwriting results, solid capitalization with growth in stockholders' equity, stable leverage metrics, and improved interest coverage metrics.

•

S&P Global Ratings ("S&P") - During the fourth quarter of 2016, S&P upgraded our financial strength rating to "A" from "A-" with a stable outlook. This rating change reflects S&P's view of our strong business risk profile and strong financial risk profile, built on our strong competitive position and very strong capital and earnings. In addition, our stable outlook reflects S&P's expectation that we will sustain our strong competitive position and operating performance.

•

Moody's Investor Service ("Moody's") - Our "A2" financial strength rating was reaffirmed in the second quarter of 2015 by Moody's. In taking this action, Moody's cited our solid regional franchise with established independent agency support, solid risk adjusted capitalization, strong invested asset quality, and good underwriting profitability. The outlook was revised to stable from negative, reflecting Moody's view of our improved profitability as a result of our stronger price adequacy in commercial lines, re-underwriting initiatives, and claims processing improvements.

Our S&P, Moody's, and Fitch financial strength and associated credit ratings affect our ability to access capital markets. The interest rate on our Line of Credit varies and is based on, among other factors, the Parent's debt ratings. There can be no assurance that our ratings will continue for any given period or that they will not be changed. It is possible that positive or negative ratings actions by one or more of the rating agencies may occur in the future.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk

The fair value of our assets and liabilities are subject to market risk, primarily interest rate, credit risk, and equity price risk related to our investment portfolio as well as fluctuations in the value of our alternative investment portfolio. The allocation of our portfolio was 92% fixed income securities, 2% equity securities, 4% short-term investments, and 2% other investments as of December 31, 2016. We do not hold derivative or commodity investments. Foreign investments are made on a limited basis, and all fixed income transactions are denominated in U.S. currency. We have minimal foreign currency fluctuation risk. For a discussion of our investment objective and philosophy, see the "Investments" section of Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." of this Form 10-K.

We manage our investment portfolio to mitigate risks associated with various financial market scenarios. We will, however, take prudent risk to enhance our overall long-term results while managing a conservative, well-diversified investment portfolio to support our underwriting activities.

Interest Rate Risk

Investment Portfolio

We invest in interest rate-sensitive securities, mainly fixed income securities. Our fixed income securities portfolio is comprised of primarily investment grade (investments receiving S&P or an equivalent rating of BBB- or above) corporate securities, U.S. government and agency securities, municipal obligations, and MBS. Our strategy to manage interest rate risk is to purchase intermediate-term fixed income investments that are attractively priced in relation to perceived credit risks.

Our exposure to interest rate risk relates primarily to the market price and cash flow variability associated with changes in interest rates. As our fixed income securities portfolio contains interest rate-sensitive instruments, it may be adversely affected by changes in interest rates resulting from governmental monetary policies, domestic and international economic and political conditions, and other factors beyond our control. A rise in interest rates will decrease the fair value of our existing fixed income investments and a decline in interest rates will result in an increase in the fair value of our existing fixed income investments. However, new and reinvested money used to purchase fixed income securities would benefit from rising interest rates and would be negatively impacted by falling interest rates.

We seek to mitigate our interest rate risk associated with holding fixed income investments by monitoring and maintaining the effective duration of our portfolio with a view toward achieving an adequate after-tax return without subjecting the portfolio to an unreasonable level of interest rate risk. The effective duration of the fixed income securities portfolio at December 31, 2016 remained stable at 3.6 years, including short-term investments, compared to a year ago. The current duration is within our historical range, and is monitored and managed to maximize yield while managing interest rate risk at an acceptable level. The Insurance Subsidiaries’ liability duration is approximately 4.0 years.

We use an interest rate sensitivity analysis to measure the potential loss or gain in future earnings, fair values, or cash flows of market sensitive fixed income securities. The sensitivity analysis hypothetically assumes an instant parallel 200 basis point shift in interest rates up and down in 100 basis point increments from the date of the Financial Statements. We use fair values to measure the potential loss. This analysis is not intended to provide a precise forecast of the effect of changes in market interest rates and equity prices on our income or stockholders’ equity. Further, the calculations do not take into account any actions we may take in response to market fluctuations, and do not take into account changes to credit spreads, liquidity spreads, and other risk factors which may also impact the value of the fixed income portfolio.

The following table presents the sensitivity analysis of interest rate risk as of December 31, 2016:



		2016 Interest Rate Shift in Basis Points
($ in thousands)		-200		-100		0	100		200

Fair value change from base (%)		6.30	%	3.57	%		(3.79	)%	(7.76	)%

Pension and Post-Retirement Benefit Plan Obligation

Our pension and post-retirement benefit obligations and related costs are calculated using actuarial methods within the framework of U.S. GAAP. The discount rate assumption is an important element of expense and/or liability measurement. Changes in the discount rate assumption could materially impact our pension and post-retirement life valuation in the future. For additional information regarding our discount rate selection, refer to Note 14. "Retirement Plans" in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Credit Risk

Our most significant credit risk is within our fixed income security portfolio, which had an overall credit quality of “AA-” as of December 31, 2016 and December 31, 2015. Exposure to non-investment grade bonds represented approximately 3% and 1% of the total fixed income securities portfolio at December 31, 2016 and 2015, respectively.

The following table summarizes the fair value, carry value, net unrealized/unrecognized gain (loss) balances, and the weighted average credit qualities of our fixed income securities at December 31, 2016 and December 31, 2015:

¹Of the $38 million in local Texas general obligation bonds, $14 million represents investments in Texas Permanent School Fund bonds, which are considered to have lower risk as a result of the bond guarantee programs that support these bonds.

Special revenue fixed income securities of municipalities (referred to as “special revenue bonds”) generally do not have the “full faith and credit” backing of the municipal or state governments, as do general obligation bonds, but special revenue bonds have a dedicated revenue stream for repayment. For our special revenue bonds, 90% of the dedicated revenue stream is comprised of the following: (i) essential services (47%), which is comprised of transportation, water and sewer, and electric; (ii) education (13%), which includes school districts and higher education, including state-wide university systems; and (iii)

special tax (30%), which are backed by a dedicated lien on a tax or other revenue repayment source. As such, we believe our special revenue bond portfolio is appropriate for the current environment.

Corporate Securities

For investment-grade corporate bonds, we address the risk of an individual issuers' default by maintaining a diverse portfolio of holdings. The primary risk related to non-investment grade corporate bonds is credit risk. A weak financial profile can lead to rating downgrades from the credit rating agencies, which can put further downward pressure on bond prices. Valuations on these bonds are related more directly to underlying operating performance than to general interest rates. Our holdings of non-investment grade corporate bonds represent less than 3% of our overall investment portfolio.

The tables below provide details on our corporate bond holdings at December 31, 2016 and December 31, 2015:



December 31, 2016	Fair Value		Carry Value	Unrealized/ Unrecognized Gain (Loss)	Weighted Average Credit Quality

Total corporate securities	$	1,922.2	1,920.2	9.6		A-

MBS Portfolio

To manage and mitigate exposure on our MBS portfolio (CMBS and RMBS), we perform analysis both at the time of purchase and as part of the ongoing portfolio evaluation. This analysis includes review of loan-to-value ratios, geographic spread of the assets securing the bond, delinquencies in payments for the underlying mortgages, gains/losses on sales, evaluations of projected cash flows, as well as other information that aids in determination of the health of the underlying assets. We consider the overall credit environment, economic conditions, total projected return on the investment, and overall asset allocation of the portfolio in our decisions to purchase or sell MBS.

CLO and Other ABS Portfolio

For CLO and other ABS, the primary risk is credit risk. We manage this risk by evaluating a number of factors, including the structuring of the deal, the credit quality of underlying loans or assets, the composition of the underlying portfolio, and the track record and capabilities of the portfolio manager. Key performance metrics, including over collateralization, interest coverage, and cash flows, are monitored on an on-going basis. We consider the overall credit environment, economic conditions, total projected return on the investment, and overall asset allocation of the portfolio in our decisions to purchase or sell CLO and other ABS.

The tables below provide details on our CLO and other ABS holdings at December 31, 2016 and December 31, 2015:



December 31, 2016	Fair Value		Carry Value	Unrealized/ Unrecognized Gain (Loss)	Weighted Average Credit Quality

Equity Price Risk

Our equity securities portfolio is exposed to risk arising from potential volatility in equity market prices. We attempt to minimize the exposure to equity price risk by maintaining a diversified portfolio and limiting concentrations in any one company or industry. The following table presents the hypothetical increases and decreases in 10% increments in market value of the equity portfolio as of December 31, 2016:



	Change in Equity Values in Percent
($ in thousands)	(30)%			(20)%		(10)%		0%	10%	20%	30%
Fair value of AFS equity portfolio	$	102,727		117,402		132,078		146,753	161,428	176,104	190,779
Fair value change	(44,026		)	(29,351	)	(14,675	)		14,675	29,351	44,026

In addition to our equity securities, we invest in certain other investments that are also subject to price risk. Our other investments primarily include alternative investments in private limited partnerships that invest in various strategies such as private equity, energy/power generation, middle market lending, mezzanine debt, distressed debt, and real estate. As of December 31, 2016, other investments represented 2% of our total invested assets and 7% of our stockholders’ equity. These investments are subject to the risks arising from the fact that their valuation is inherently subjective. The general partner of each of these partnerships usually reports the change in the value of the interests in the partnership on a one quarter lag because of the nature of the underlying assets or liabilities. Since these partnerships' underlying investments consist primarily of assets or liabilities for which there are no quoted prices in active markets for the same or similar assets, the valuation of interests in these partnerships are subject to a higher level of subjectivity and unobservable inputs than substantially all of our other investments. Each of these general partners is required to determine the partnerships' value by the price obtainable for the sale of the interest at the time of determination. Valuations based on unobservable inputs are subject to greater scrutiny and reconsideration from one reporting period to the next and therefore, may be subject to significant fluctuations, which could lead to significant decreases from one reporting period to the next. As we record our investments in these various partnerships under the equity method of accounting, any decreases in the valuation of these investments would negatively impact our results of operations.

For additional information regarding these alternative investment strategies, see Note 5. “Investments” in Item 8. “Financial Statements and Supplementary Data.” of this Form 10-K.

Indebtedness

(a) Long-Term Debt

As of December 31, 2016, we had outstanding long-term debt of $438.7 million that matures as shown in the following table:



		2016
($ in thousands)	Year of Maturity	Carrying Amount			Fair Value
Financial liabilities
Long-term debt
1.61% Borrowings from FHLBNY	2021	$	25,000		24,286

Subtotal		444,331			449,159
Unamortized debt issuance costs		(5,664		)
Total notes payable		$	438,667

The weighted average effective interest rate for our outstanding long-term debt was 5.3% at December 31, 2016. Our debt is not exposed to material changes in interest rates because the interest rates are fixed.

Refer to Note 10. "Indebtedness", within Item 8. "Financial Statements and Supplementary Data." of this Form 10-K for discussion on debt covenant provisions.

(b) Short-Term Debt

Our Line of Credit with Wells Fargo Bank, National Association, as administrative agent, and Branch Banking and Trust Company (BB&T), was renewed effective December 1, 2015 with a borrowing capacity of $30 million, which can be increased to $50 million with the approval of both lending partners.

The Line of Credit provides the Parent with an additional source of short-term liquidity. The interest rate on our Line of Credit varies and is based on, among other factors, the Parent’s debt ratings. The Line of Credit expires on December 1, 2020. There were no balances outstanding under this Line of Credit or the previous credit facility at December 31, 2016 or at any time during 2016.

Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Selective Insurance Group, Inc. and its subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the years in the three‑year period ended December 31, 2016, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Selective Insurance Group, Inc. and its subsidiaries' internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 21, 2017, expressed an unqualified opinion on the effectiveness of the Company’s internal controls over financial reporting.

Notes to Consolidated Financial Statements

Note 1. Organization

Selective Insurance Group, Inc., through its subsidiaries, (collectively referred to as “we,” “us,” or “our”) offers standard commercial, standard personal, and excess and surplus ("E&S") lines property and casualty insurance products. Selective Insurance Group, Inc. (referred to as the “Parent”) was incorporated in New Jersey in 1977 and its main offices are located in Branchville, New Jersey. The Parent’s common stock is publicly traded on the NASDAQ Global Select Market under the symbol “SIGI.” We have provided a glossary of terms as Exhibit 99.1 to this Form 10-K, which defines certain industry-specific and other terms that are used in this Form 10-K.

We classify our business into four reportable segments, which are as follows:


•	Standard Commercial Lines - comprised of insurance products and services provided in the standard marketplace to commercial enterprises, which are typically businesses, non-profit organizations, and local government agencies.


•	Standard Personal Lines - comprised of insurance products and services, including flood insurance coverage, provided primarily to individuals acquiring coverage in the standard marketplace.


•	E&S Lines - comprised of insurance products and services provided to customers who have not obtained coverage in the standard marketplace.


•	Investments - invests the premiums collected by our insurance operations, as well as amounts generated through our capital management strategies, which may include the issuance of debt and equity securities.

Note 2. Summary of Significant Accounting Policies

(a) Principles of Consolidation

The accompanying consolidated financial statements (“Financial Statements”) include the accounts of the Parent and its subsidiaries, and have been prepared in conformity with: (i) U.S. generally accepted accounting principles ("GAAP"); and (ii) the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation.

(b) Use of Estimates

The preparation of our Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported financial statement balances, as well as the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Certain amounts in our prior years' Financial Statements and related notes have been reclassified to conform to the 2016 presentation. Such reclassifications had no effect on our net income, stockholders' equity, or cash flows.

(d) Investments

Fixed income securities may include investment grade and below investment grade rated bonds, redeemable preferred stocks, non-redeemable preferred stocks with certain debt-like characteristics, mortgage-backed securities (“MBS”), collateralized loan obligations ("CLO") and other asset-backed securities (“ABS”). MBS, CLO, and other ABS are jointly referred to as structured securities. Fixed income securities classified as available-for-sale (“AFS”) are reported at fair value. Those fixed income securities that we have the ability and positive intent to hold to maturity are classified as held-to-maturity (“HTM”) and are carried at either: (i) amortized cost; or (ii) market value at the date of transfer into the HTM category, adjusted for subsequent amortization. The amortized cost of fixed income securities is adjusted for the amortization of premiums and the accretion of discounts over the expected life of the security using the effective yield method. Premiums and discounts arising from the purchase of structured securities are amortized over the expected life of the security based on future principal payments, and considering prepayments. These prepayments are estimated based on historical and projected cash flows. Prepayment assumptions are reviewed quarterly and adjusted to reflect actual prepayments and changes in expectations. Future amortization of any premium and/or discount is adjusted to reflect the revised assumptions. Interest income, as well as amortization and accretion, is included in "Net investment income earned" on our Consolidated Statements of Income. The amortized cost of a fixed income security is written down to fair value when a decline in value is considered to be other than temporary. See the discussion below on realized investment gains and losses for a description of the accounting for impairments. After-tax unrealized gains and losses on: (i) fixed income securities classified as AFS; and (ii) fixed income securities that were transferred into an HTM designation from an AFS designation, are included in accumulated other comprehensive income (loss) ("AOCI").

Equity securities, which are classified as AFS, may include common and non-redeemable preferred stocks. These securities are carried at fair value and the related dividend income is included in "Net investment income earned" on our Consolidated Statements of Income. The cost of equity securities is written down to fair value when a decline in value is considered to be other than temporary. See the discussion below on realized investment gains and losses for a description of the accounting for impairments. After-tax unrealized gains and losses are included in AOCI.

Short-term investments may include certain money market instruments, savings accounts, commercial paper, and debt issues purchased with a maturity of less than one year. We also enter into reverse repurchase agreements that are included in short-term investments. These loans are fully collateralized with high quality, readily marketable instruments at a minimum of 102% of the loan principal. At maturity, we receive principal and interest income on these agreements. All short-term investments are carried at cost, which approximates fair value. The associated income is included in "Net investment income earned" on our Consolidated Statement of Income.

Other investments may include alternative investments and other securities. Alternative investments are accounted for using the equity method. Our share of distributed and undistributed net income from alternative investments is included in "Net investment income earned" on our Consolidated Statement of Income. Other securities are primarily comprised of tax credit investments. Low income housing tax credits are accounted for under the proportional amortization method and all other tax credits are accounted for using the equity method. Under the proportional amortization method, our share of the investment’s performance is recorded in our Consolidated Statement of Income as a component of “Federal income tax expense.” Under the equity method, our share of distributed and undistributed net income is included in "Net investment income earned" on our Consolidated Statement of Income. For federal income tax credits accounted for under the equity method, we use the deferral method for recognizing the benefit of the tax credit with the related deferred revenue being recognized in our Consolidated Statement of Income as a component of "Federal income tax expense" ratably over the life of the investment.

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold and are credited or charged to income. Included in realized gains and losses are the other-than-temporary impairment ("OTTI") charges recognized in earnings, which are discussed below.

On a quarterly basis, we review our investment portfolio for impairments that are other than temporary. The following provides information on this analysis for our fixed income securities and short-term investments, our equity securities, and our other investments.

Fixed Income Securities and Short-Term Investments

We review securities that are in an unrealized loss position to determine: (i) if we have the intent to sell the security; (ii) if it is more likely than not that we will be required to sell the debt security before its anticipated recovery; and (iii) if the decline is other than temporary. Broad changes in the overall market or interest rate environment generally will not lead to a write down. If we determine that we have either the intent or requirement to sell the security, we write down its amortized cost to its fair value through a charge to earnings as a component of realized losses. If we do not have either the intent or requirement to sell the security, our evaluation for OTTI may include, but is not limited to, evaluation of the following factors:


•	Whether the decline appears to be issuer or industry specific;


•	The degree to which the issuer is current or in arrears in making principal and interest payments on the fixed income security;


•	The issuer’s current financial condition and ability to make future scheduled principal and interest payments on a timely basis;


•	Evaluation of projected cash flows;


•	Buy/hold/sell recommendations published by outside investment advisors and analysts; and


•	Relevant rating history, analysis, and guidance provided by rating agencies and analysts.

Non-redeemable preferred stocks that are classified as fixed income securities are evaluated under this OTTI method unless the security is below investment grade, at which time they are evaluated under the equity securities OTTI model discussed below.

To determine if an impairment is other than temporary, we perform assessments that may include, but are not limited to, discounted cash flow analyses ("DCFs") to determine the security's present value of future cash flows. In addition, this analysis is performed on all previously-impaired debt securities that continue to be held by us and all structured securities that were not of high-credit quality at the date of purchase. Any shortfall in the expected present value of the future cash flows, based on the DCF, from the amortized cost basis of a security is considered a “credit impairment,” with the remaining decline in fair value of

a security considered a “non-credit impairment.” Credit impairments are charged to earnings as a component of realized losses, while non-credit impairments are recorded to Other Comprehensive Income ("OCI") as a component of unrealized losses.

The discount rate we use in a DCF is the effective interest rate implicit in the security at the date of acquisition for those structured securities that were not of high-credit quality at acquisition. For all other securities, we use a discount rate that equals the current yield, excluding the impact of previous OTTI charges, used to accrete the beneficial interest. Discounted cash flow models may include, but are not necessarily limited to: (i) generating cash flows for each tranche considering tranche-specific data, market data, and other pertinent information such as the historical performance of the underlying collateral, including net operating income generated by underlying properties, conditional default rate assumptions, loan loss severity assumptions, consensus projections, prepayment projections, and actual pool and collateral information; (ii) identifying applicable benchmark yields; and (iii) applying market-based tranche specific spreads to determine an appropriate yield by incorporating collateral performance, tranche-level attributes, trades, bids, and offers.

Equity Securities

We review securities that are in an unrealized loss position to determine: (i) if we do not intend to hold the security to its forecasted recovery; or (ii) if the decline is other than temporary, which includes declines driven by market volatility for which we cannot assert will recover in the near term. If we determine either that we do not intend to hold a security, or the decline is other than temporary, we write down the security's cost to its fair value through a charge to earnings as a component of realized losses. If we intend to hold the security, our evaluation for OTTI may include, but is not limited to, an evaluation of the following factors:


•	Whether the decline appears to be issuer or industry specific;


•	The relationship of market prices per share to book value per share at the date of acquisition and date of evaluation;


•	The price-earnings ratio at the time of acquisition and date of evaluation;


•	The financial condition and near-term prospects of the issuer, including any specific events that may influence the issuer's operations, coupled with our intention to hold the securities in the near-term;


•	The recent income or loss of the issuer;


•	The independent auditors' report on the issuer's recent financial statements;


•	The dividend policy of the issuer at the date of acquisition and the date of evaluation;


•	Buy/hold/sell recommendations or price projections published by outside investment advisors;


•	Rating agency announcements;


•	The length of time and the extent to which the fair value has been, or is expected to be, less than its cost in the near term; and


•	Our expectation of when the cost of the security will be recovered.

Other Investments

Our evaluation for OTTI of an other investment (i.e., an alternative investment) may include, but is not limited to, conversations with the management of the alternative investment concerning the following:


•	The current investment strategy;


•	Changes made or future changes to be made to the investment strategy;


•	Emerging issues that may affect the success of the strategy; and


•	The appropriateness of the valuation methodology used regarding the underlying investments.

If there is a decline in the fair value of an other investment that we do not intend to hold, or if we determine the decline is other than temporary, we write down the carry value of the investment and record the charge through earnings as a component of realized losses.

(e) Fair Values of Financial Instruments

Assets

The fair values of our investments are generated using various valuation techniques and are placed into the fair value hierarchy considering the following: (i) the highest priority is given to quoted prices in active markets for identical assets (Level 1); (ii) the next highest priority is given to quoted prices in markets that are not active or inputs that are observable either directly or indirectly, including quoted prices for similar assets in markets that are not active and other inputs that can be derived principally from, or corroborated by, observable market data for substantially the full term of the assets (Level 2); and (iii) the lowest priority is given to unobservable inputs supported by little or no market activity and that reflect our assumptions about the exit price, including assumptions that market participants would use in pricing the asset (Level 3). An asset’s classification within the fair value hierarchy is based on the lowest level of significant input to its valuation. Transfers between levels in the fair value hierarchy are recognized at the end of the reporting period.

The techniques used to value our financial assets are as follows:

Level 1 Pricing



Security Type	Methodology
Equity Securities; U.S. Treasury Notes	Equity and U.S. Treasury Note prices are received from an independent pricing service that are based on observable market transactions. We validate these prices against a second external pricing service, and if established market value comparison thresholds are breached, further analysis is performed to determine the price to be used.
Short-Term Investments	Short-term investments are carried at cost, which approximates fair value. Given the liquid nature of our short-term investments, we generally validate their fair value by way of active trades within approximately one week of the financial statement close.

Level 2 Pricing

We utilize a market approach for our Level 2 securities, using primarily matrix pricing models prepared by external pricing services. Matrix pricing models use mathematical techniques to value debt securities by relying on the securities' relationship to other benchmark quoted securities, and not relying exclusively on quoted prices for specific securities, as the specific securities are not always frequently traded. As a matter of policy, we consistently use one pricing service as our primary source and secondary pricing services if prices are not available from the primary pricing service. Fixed income securities portfolio pricing is reviewed for reasonableness in the following ways: (i) comparing our pricing to other third-party pricing services as well as benchmark indexed pricing; (ii) comparing fair value fluctuations between months for reasonableness; and (iii) reviewing stale prices. If further analysis is needed, a challenge is sent to the pricing service for review and confirmation of the price.

Further information on our Level 2 asset pricing is included in the following table:



Security Type	Methodology
Corporate Securities including preferred stocks classified as Fixed Income Securities, and U.S. Government and Government Agencies	Evaluations include obtaining relevant trade data, benchmark quotes and spreads and incorporating this information into either spread-based or price-based evaluations as determined by the observed market data. Spread-based evaluations include: (i) creating a range of spreads for relevant maturities of each issuer based on the new issue market, secondary trading, and dealer quotes; and (ii) incorporating option adjusted spreads for issues that have early redemption features. Based on the findings in (i) and (ii) above, final spreads are derived and added to benchmark curves. Price-based evaluations include matching each issue to its best-known market maker and contacting firms that transact in these securities.
Obligations of States and Political Subdivisions	Evaluations are based on yield curves that are developed based on factors such as: (i) benchmarks to issues with interest rates near prevailing market rates; (ii) established trading spreads over widely-accepted market benchmarks; (iii) yields on new issues; and (iv) market information from third-party sources such as reportable trades, broker-dealers, or issuers.
Structured Securities (including CLO and other ABS, CMBS, RMBS)	Evaluations are based on a discounted cash flow model, including: (i) generating cash flows for each tranche considering tranche-specific data, market data, and other pertinent information such as historical performance of the underlying collateral, including net operating income generated by the underlying properties, conditional default rate assumptions, loan loss severity assumptions, consensus projections, prepayment projections, and actual pool and loan level collateral information; (ii) identifying applicable benchmark yields; and (iii) applying market-based tranche-specific spreads to determine an appropriate yield by incorporating collateral performance, tranche-level attributes, trades, bids, and offers.
Foreign Government	Evaluations are performed using a DCF model and incorporating observed market yields of benchmarks as inputs, adjusting for varied maturities.

Level 3 Pricing

Less than 1% of our portfolio cannot be priced using our primary or secondary pricing service. At times, we may use non-binding broker quotes to value some of these securities. These prices are from various broker/dealers that use bid or ask prices, or benchmarks to indices, in measuring the fair value of a security. We review these fair value measurements for reasonableness. This review typically includes an analysis of price fluctuations between months with variances over established thresholds being analyzed further.

Further information on our current Level 3 asset pricing is included in the following table:



Security Type	Methodology
Corporate Securities	These tax credit investments are priced internally using spread-based evaluations.
Equity Securities	These non-publicly traded stocks are valued by the issuer and reviewed internally.

See Note 7. “Fair Value Measurements” for a summary table of the fair value and related carrying amounts of financial instruments.

(f) Allowance for Doubtful Accounts

We estimate an allowance for doubtful accounts on our premiums receivable. This allowance is based on historical write-off percentages adjusted for the effects of current and anticipated trends. An account is charged off when we believe it is probable that we will not collect a receivable. In making this determination, we consider information obtained from our efforts to collect amounts due directly and/or through collection agencies.

(g) Share-Based Compensation

Share-based compensation consists of all share-based payment transactions in which an entity acquires goods or services by issuing (or offering to issue) its shares, share units, share options, or other equity instruments. The cost resulting from all share-based payment transactions are recognized in the Financial Statements based on the fair value of both equity and liability awards. The fair value is measured at grant date for equity awards, whereas the fair value for liability awards are remeasured at each reporting period. Both the fair value of equity and liability awards is recognized over the requisite service period. The requisite service period is typically the lesser of the vesting period or the period of time from the grant date to the date of retirement eligibility. The expense recognized for share-based awards, which, in some cases, contain performance criteria, is based on the number of shares or units expected to be issued at the end of the performance period. We repurchase the Parent’s stock from our employees in connection with, and as permitted under, our stock-based compensation plans. This activity is disclosed in our Consolidated Statements of Stockholders' Equity.

(h) Reinsurance

Reinsurance recoverables represent estimates of amounts that will be recovered from reinsurers under our various treaties. Generally, amounts recoverable from reinsurers are recognized as assets at the same time and in a manner consistent with the paid and unpaid losses associated with the reinsured policies. We require collateral to secure reinsurance recoverables primarily from our reinsurance carriers that are not authorized, otherwise approved, or certified to do business in one or more of our ten insurance subsidiaries' domiciliary states. Our ten insurance subsidiaries are collectively referred to as the "Insurance Subsidiaries". This collateral is typically in the form of a letter of credit or cash. An allowance for estimated uncollectible reinsurance is recorded based on an evaluation of balances due from reinsurers and other available information, such as each reinsurers' credit rating from A.M. Best Company ("A.M. Best") or Standard & Poor's Rating Services ("S&P"). We charge off reinsurance recoverables on paid losses when it becomes probable that we will not collect the balance.

(i) Property and Equipment

Property and equipment used in operations, including certain costs incurred to develop or obtain computer software for internal use, are capitalized and carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. The following estimated useful lives can be considered as general guidelines:



Asset Category		Years
Computer hardware		3
Computer software		3 to 5
Internally developed software		5 to 10
Software licenses		3 to 5
Furniture and fixtures		10
Buildings and improvements		5 to 40

We recorded depreciation expense of $17.4 million, $16.4 million, and $12.6 million for 2016, 2015, and 2014, respectively.

(j) Deferred Policy Acquisition Costs

Deferred policy acquisition costs are limited to costs directly related to the successful acquisition of insurance contracts. Costs meeting this definition typically include, among other things, sales commissions paid to our distribution partners, premium taxes, and the portion of employee salaries and benefits directly related to time spent on acquired contracts. These costs are deferred and amortized over the life of the contracts.

Accounting guidance requires a premium deficiency analysis to be performed at the level an entity acquires, services, and measures the profitability of its insurance contracts. We currently perform three premium deficiency analyses for our insurance segments, consistent with our reportable segments of Standard Commercial Lines, Standard Personal Lines, and E&S Lines. A combined ratio of over 100% does not necessarily indicate a premium deficiency, as any year's combined ratio includes a portion of underwriting expenses that are expensed at policy inception and therefore are not covered by the remaining unearned premium. In addition, investment income is not contemplated in the combined ratio calculation.

There were no premium deficiencies for any of the reported years, as the sum of the anticipated losses and loss expenses, unamortized acquisition costs, policyholder dividends, and other expenses for each segment did not exceed that segment’s related unearned premium and anticipated investment income. The investment yields assumed in the premium deficiency assessment for each reporting period, which are based on our actual average investment yield before tax as of the September 30 calculation date, were 2.4% for 2016, 2.5% for 2015, and 3.0% for 2014. Deferred policy acquisition costs amortized to expense were $450.3 million for 2016, $399.4 million for 2015, and $364.3 million for 2014.

(k) Goodwill

Goodwill results from business acquisitions where the cost of assets and liabilities acquired exceeds the fair value of those assets and liabilities. A quantitative goodwill impairment analysis is performed if our quarterly qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Goodwill is allocated to the reporting units for purposes of these analyses. Based on our analysis at December 31, 2016, goodwill was not impaired.

(l) Reserves for Losses and Loss Expenses

Reserves for losses and loss expenses are comprised of both case reserves on individual claims, and reserves for claims incurred but not reported ("IBNR"). Case reserves result from claims that have been reported to one or more of our Insurance Subsidiaries, and are estimated at the amount of the expected ultimate payment. IBNR reserves are established at more aggregated levels than case basis reserves, and in addition to reserves on claims that have been incurred but not reported, they include provisions for future emergence on known claims, as well as reopened claims. IBNR reserves are established based on the results of the Insurance Subsidiaries’ internal reserve analysis, supplemented with other internal and external information.

The internal reserve analysis is performed quarterly, and relies upon generally accepted actuarial techniques. Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for predicting future events. Our analyses rely upon historical paid and case losses and loss adjustment expense experience organized by line of business, accident year and maturity (i.e., “triangles”). Standard actuarial projection methods are applied to this history, producing a set of estimated ultimate losses and loss adjustment expenses. Ultimate losses and loss adjustment expenses are selected from the various methods, considering the strengths and weaknesses of the methods as they apply to the specific line and accident year.

Certain types of exposures do not lend themselves to standard actuarial methods. Examples of these are:

•

Certain property catastrophe events may be low in frequency and high in severity. These events may affect many insureds simultaneously. Due to the unique nature of these events, ultimate liabilities are estimated for each event, based on surveys of our portfolio of exposures, in conjunction with individual claims estimates. While generally short-tailed, the liabilities associated with these events are subject to a higher degree of uncertainty. We maintain significant reinsurance protection that greatly limits the impact that these extreme events have on net loss and loss adjustment expenses.

•

In some limited cases, an insured event may span multiple years and multiple policies, as in the case of asbestos and environmental claims, where the injury is deemed to occur over an extended period of time. These claims are analyzed without accident year detail, using alternative methods and metrics. The associated selected ultimate loss and loss adjustment expenses are then allocated to accident year for reporting.


•	Another example of non-standard methods relate to loss adjustment expenses that cannot be attributed to a specific claim (referred to as “unallocated loss adjustment expenses”). These expenses are first allocated to accident year and alternative projection methods are then applied to these expenses. The resulting ultimate expenses by accident year are then used for reporting purposes.

The selected ultimate losses and loss adjustment expenses are translated into indicated IBNR reserves, which are then compared to the recorded IBNR reserves. Management's judgment is applied in determining any required adjustments and the resulting adjustments are then recorded and assigned or allocated to accident year using the results of the actuarial analysis.

While the reserve analysis is the primary basis for determining the recorded IBNR reserves, other internal and external factors are considered. Internal factors include: (i) supplemental data regarding claims reporting and settlement trends; (ii) exposure estimates for reported claims, along with recent development on those estimates with respect to individual large claims and the aggregate of all claims; (iii) the rate at which new large or complex claims are being reported; and (iv) additional trends observed by claims personnel or reported to them by defense counsel. External factors considered include: (i) legislative enactments; (ii) judicial decisions; (iii) legal developments in the determination of liability and the imposition of damages; and (iv) trends in general economic conditions, including the effects of inflation.

Loss reserves are estimates, and as such, we also consider a range of possible loss and loss expense reserve estimates. This range is determined at the beginning of each year, using prior year-end data, and reflects the fact that there is no single precise method for estimating the required reserves, due to the many factors that may influence the amounts ultimately paid. Considering the reserve range along with all of the items described above, as well as current market conditions, IBNR estimates are then established and recorded.

The combination of the IBNR estimates along with the case reserve estimates on individual claims results in our total reserves for losses and loss expenses. These reserves are expected to be sufficient for settling losses and loss reserve obligations under our policies on unpaid claims, including changes in the volume of business written, claims frequency and severity, the mix of business, claims processing, and other items that management expects to affect our ultimate settlement of losses and loss expenses. However, the ultimate claim settlements may be higher or lower than reserves established. As our experience emerges and other information develops, we revise our reserve estimates accordingly. The changes in these estimates, resulting from the continuous review process and the differences between estimates and ultimate payments, are reflected in the Consolidated Statements of Income for the period in which such estimates are changed. The associated impacts may be material to the results of operations in future periods.

We do not discount to present value that portion of our losses and loss expense reserves expected to be paid in future periods.

Our loss and loss expense reserves implicitly include anticipated recoveries for salvage and subrogation claims.

Claims are counted at the occurrence, line of business, and policy level. For example, if a single occurrence (e.g. an auto accident) leads to a claim under an auto and an associated umbrella policy, they are each counted separately. Conversely, multiple claimants under the same occurrence/line/policy would contribute only a single count. The claim counts provided are on a reported basis. A claim is considered reported when a reserve is established or payment is made. Therefore, claims closed without payment are included in the count as long as there was an associated case reserve at some point in its life cycle.

We also write a small amount of assumed reinsurance. Currently, this business is limited to our share of certain involuntary pools. Since the associated claims are not processed by us, they are not captured within our claims system. Therefore, the claim counts reported exclude this business.

(m) Revenue Recognition

The Insurance Subsidiaries' net premiums written (“NPW”) include direct insurance policy writings, plus reinsurance assumed and estimates of premiums earned but unbilled on the workers compensation and general liability lines of insurance, less reinsurance ceded. The estimated premium on the workers compensation and general liability lines is referred to as audit premium. We estimate this premium, as it is anticipated to be either billed or returned on policies subsequent to expiration based on exposure levels (i.e. payroll or sales). Audit premium is based on historical trends adjusted for the uncertainty of future economic conditions. Economic instability could ultimately impact our estimates and assumptions, and changes in our estimate may be material to the results of operations in future periods. Premiums written are recognized as revenue over the period that coverage is provided using the semi-monthly pro-rata method. Unearned premiums and prepaid reinsurance premiums represent that portion of premiums written that are applicable to the unexpired terms of policies in force.

(n) Dividends to Policyholders

We establish reserves for dividends to policyholders on certain policies, most significantly workers compensation policies. These dividends are based on the policyholders' loss experience. Dividend reserves are established based on past experience, adjusted for the effects of current developments and anticipated trends. The expense for these dividends is recognized over a period that begins at policy inception and ends with the payment of the dividend. We do not issue policies that entitle the policyholder to participate in the earnings or surplus of our Insurance Subsidiaries.

(o) Federal Income Tax

We use the asset and liability method of accounting for income taxes. Current federal income taxes are recognized for the estimated taxes payable or refundable on tax returns for the current year. Deferred federal income taxes arise from the recognition of temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. We consider all evidence, both positive and negative, with respect to our federal tax loss carryback availability, expected levels of pre-tax financial statement income, and federal taxable income, when evaluating whether the temporary differences will be realized. In projecting future taxable income, we begin with budgeted pre-tax income adjusted for estimated non-taxable items. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we use to manage our businesses. A valuation allowance is established when it is more likely than not that some portion of the deferred tax asset will not be realized. A liability for uncertain tax positions is recorded when it is more likely than not that a tax position will not be sustained upon examination by taxing authorities. The effect of a change in tax rates is recognized in the period of enactment. If we were to be levied interest and penalties by the Internal Revenue Service (“IRS”), the interest would be recognized as “Interest expense” and the penalties would be recognized as “Other expenses” on the Consolidated Statements of Income.

(p) Leases

We have various operating leases for office space, equipment, and fleet vehicles. Rental expense for such leases is recorded on a straight-line basis over the lease term. If a lease has a fixed and determinable escalation clause, or periods of rent holidays, the difference between rental expense and rent paid is included in "Other liabilities" as deferred rent in the Consolidated Balance Sheets.

In addition, we have various capital leases for computer hardware and software. These leases are accounted for as an acquisition of an asset and an incurrence of an obligation. Depreciation is calculated using the straight-line method over the shorter of the estimated useful life of the asset or the lease term.

(q) Pension

Our pension and post-retirement life benefit obligations and related costs are calculated using actuarial methods, within the framework of GAAP. Our pension benefit obligation is determined as the actuarial present value of the vested benefits to which the employee is currently entitled, based on the average life expectancy of the employee. Our funding policy provides that payments to our pension trust shall be equal to the minimum funding requirements of the Employee Retirement Income Security Act, plus additional amounts that the Board of Directors of Selective Insurance Company of America (“SICA”) may approve from time to time.

Two key assumptions, the discount rate and the expected return on plan assets, are important elements of expense and/or liability measurement. We evaluate these key assumptions annually unless facts indicate that a more frequent review is required. The discount rate enables us to state expected future cash flows at their present value on the measurement date. The purpose of the discount rate is to determine the interest rates inherent in the price at which pension benefits could be effectively

settled. Our discount rate selection is based on high-quality, long-term corporate bonds. To determine the expected long-term rate of return on the plan assets, we consider the current and expected asset allocation, as well as historical and expected returns on each plan asset class. Other assumptions involve demographic factors such as retirement age and mortality.

Note 3. Adoption of Accounting Pronouncements

In January 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-01, Accounting for Investments in Qualified Affordable Housing Projects ("ASU 2014-01"). ASU 2014-01 applies to all reporting entities that invest in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for a low-income housing tax credit. ASU 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using a newly defined "proportional amortization method" if certain conditions are met. This policy election is required to be applied consistently to all qualifying investments, rather than a decision to be applied to individual investments. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the Consolidated Statements of Income as components of "Federal income tax expense". We adopted this guidance in the third quarter of 2014 and have made a policy election to use the proportional amortization method. The adoption of this guidance did not materially impact our financial condition or results of operations.

In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (“ASU 2014-12”). ASU 2014-12 requires that performance targets that affect vesting and could be achieved after the requisite service period be treated as performance conditions. The adoption of ASU 2014-12 in the first quarter of 2016 did not affect us, as we have historically recorded expense consistent with the requirements of this accounting update.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. Our adoption of this amendment in the fourth quarter of 2016 did not affect us, as the additional disclosure requirements are applicable only to entities that have been subject to events or conditions that cast substantial doubt as to whether the entity has the ability to continue as a going concern.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 affects the following areas: (i) limited partnerships and similar legal entities; (ii) the evaluation of fees paid to a decision maker

or a service provider as a variable interest; (iii) the effect of fee arrangements on the primary beneficiary determination; (iv) the

effect of related parties on the primary beneficiary determination; and (v) certain investment funds. We adopted this guidance

in the first quarter of 2016. Under the new guidance, our limited partnership and tax credit investments are variable interest

entities ("VIEs"); however, we are not the primary beneficiary of any of these investments. As such, the adoption had no

impact on our financial condition or results of operations. The required disclosures related to our VIEs are included in Note 5.

“Investments” below.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 requires debt issuance costs to be netted against the related debt liability in the balance sheet rather than presented as a separate asset. However, ASU 2015-03 does not address the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Therefore, in August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (“ASU 2015-15”). ASU 2015-15 clarifies that, in the absence of authoritative guidance on line-of-credit arrangements within ASU 2015-03, the SEC would not object to the deferral and presentation of debt issuance costs as an asset and the subsequent amortization of the deferred costs over the term of the line-of-credit arrangement. We adopted this guidance retrospectively, effective in the fourth quarter of 2015. As such, 2014 balances in this Form 10-K have been restated to reflect the revised guidance, as follows:



Income Statement Information
Year ended December 31, 2014
($ in thousands)	As Originally Reported		As Restated
Interest Expense	$	22,086	23,063
Other Expense	33,673		32,696

In April 2015, the FASB issued ASU 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement

(“ASU 2015-05”). ASU 2015-05 provides guidance to customers with cloud computing arrangements that include a software

license. If a cloud computing arrangement includes a software license, the customer's accounting for the software license

element of the arrangement is consistent with the acquisition of other software licenses. If a cloud computing arrangement

does not include a software license, the customer accounts for the arrangement as a service contract. We adopted this guidance

in the first quarter of 2016, with prospective application. The impact of this adoption did not have a material effect on our

financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value

per Share (or Its Equivalent) (“ASU 2015-07”). ASU 2015-07 provides that investments for which the practical expedient is

used to measure fair value at net asset value per share ("NAV") must be removed from the fair value hierarchy. Instead, those

investments must be included as a reconciling line item so that the total fair value amount of investments in the disclosure is

consistent with the amount on the balance sheet. ASU 2015-07 also includes disclosure requirements for investments for which

the NAV practical expedient was used to determine fair value. We adopted this guidance in the first quarter of 2016 and have included the related disclosures in Note 14. "Retirement Plans" below.

In May 2015, the FASB issued ASU 2015-09, Disclosures about Short-Duration Contracts (“ASU 2015-09”). ASU 2015-09 requires companies that issue short duration contracts to disclose additional information, including: (i) incurred and paid claims development tables; (ii) frequency and severity of claims; and (iii) information about material changes in judgments made in calculating the liability for unpaid claim adjustment expenses, including reasons for the change and the effects on the financial statements. We adopted this guidance in the fourth quarter of 2016 and have included the related disclosures in Note 9. "Reserves for Losses and Loss Expenses" below.

Pronouncements to be effective in the future

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Sub-topic 825-10): Recognition and

Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 provides guidance to improve

certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Specifically the guidance:

(i) requires equity investments to be measured at fair value with changes in fair value recognized in earnings; (ii) simplifies the

impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to

identify impairment; (iii) eliminates the requirement to disclose the methods and significant assumptions used to estimate the

fair value that is required to be disclosed for financial instruments measured at amortized cost; (iv) requires the use of the exit

price notion when measuring the fair value of financial instruments for disclosure purposes; and (v) clarifies that the need for a

valuation allowance on a deferred tax asset related to an available-for-sale ("AFS") security should be evaluated with other

deferred tax assets.

ASU 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual

periods. Early application to financial statements of annual or interim periods that have not yet been issued are permitted as of

the beginning of the year of adoption, otherwise early adoption of ASU 2016-01 is not permitted. We are currently evaluating

the impact of this guidance on our financial condition and results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires all lessees to

recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the

lease commencement date. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim

reporting periods within that annual period, with early adoption permitted. ASU 2016-02 requires the application of a modified

retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in

the financial statements. While we are currently evaluating ASU 2016-02, we do not expect a material impact on our financial

condition or results of operations from the adoption of this guidance.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee

Share-based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based

payment transactions including: (i) income tax consequences; (ii) classification of awards as either equity or liabilities; (iii)

forfeitures assumptions; and (iv) cash flow classification. ASU 2016-09 is effective for annual periods beginning after

December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. We do not expect this ASU to have a material impact on our financial condition or results of operations.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13”). ASU 2016-13 will

change the way entities recognize impairment of financial assets by requiring immediate recognition of estimated credit losses

expected to occur over the remaining life of many financial assets, including, among others, HTM debt securities,

trade receivables, and reinsurance receivables. ASU 2016-13 requires a valuation allowance to be calculated on these financial

assets and that they be presented on the financial statements net of the valuation allowance. The valuation allowance is a

measurement of expected losses that is based on relevant information about past events, including historical experience, current

conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This methodology is

referred to as the current expected credit loss model. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, but no earlier than annual periods

beginning after December 15, 2018. We are currently evaluating the impact of this guidance on our financial condition and

results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (“ASU 2016-15”). ASU 2016-15 adds or clarifies

guidance on the classification of certain cash receipts and payments in the statements of cash flows including, but not limited to: (i) debt prepayment or debt extinguishment costs; (ii) proceeds from the settlement of corporate-owned life insurance policies including bank-owned life insurance policies; (iii) distributions received from equity method investees; and (iv) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. We are currently evaluating the impact of this guidance on our statements of cash flows.

In October 2016, the FASB issued ASU 2016-17, Consolidation: Interests Held through Related Parties That Are Under Common Control ("ASU 2016-17"). ASU 2016-17 changes how a decision maker considers indirect interests in a VIE held under common control in making the primary beneficiary determination. ASU 2016-17 will be effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods. We do not expect this ASU to impact us as we are not the decision maker in any of the VIEs in which we are invested.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash ("ASU 2016-18"). ASU 2016-18, requires that restricted cash and restricted cash equivalents be included with cash and cash equivalents in the reconciliation of beginning and ending cash on the statements of cash flows. This update also requires a reconciliation of the statement of the cash flows to the balance sheet if the balance sheet includes more than one line item of cash, cash equivalents, and restricted cash. ASU 2016-18 is effective, with retrospective adoption, for annual periods beginning after December 15, 2017, and interim periods within those annual periods. We are currently evaluating the impact of this guidance on our statements of cash flows.

Unrealized gains and losses of AFS securities represent fair value fluctuations from the later of: (i) the date a security is designated as AFS; or (ii) the date that an OTTI charge is recognized on an AFS security, through the date of the balance sheet. These unrealized gains and losses are recorded in AOCI on the Consolidated Balance Sheets.

(d) The table below provides our net unrealized/unrecognized loss positions by impairment severity for both AFS and HTM securities as of December 31, 2016 compared to the prior year:



($ in thousands)

The severity of impairment on the securities in the table above averaged 1% of amortized cost at December 31, 2016 and December 31, 2015. The decrease in the unrealized/unrecognized loss balance during 2016 was primarily from our AFS corporate fixed income securities portfolio, which was positively impacted by tightening credit spreads.

Quantitative information regarding unrealized losses on our AFS portfolio is provided below. Our HTM portfolio had $0.2 million in unrealized/unrecognized losses at December 31, 2016 and no unrealized/unrecognized losses at December 31, 2015.

We do not intend to sell any of the securities in the tables above, nor do we believe we will be required to sell any of these securities. Additionally, we have reviewed these securities in accordance with our OTTI policy, as described in Note 2. “Summary of Significant Accounting Policies” of this Form 10-K and have concluded that they are temporarily impaired. This conclusion reflects our current judgment as to the financial position and future prospects of the entity that issued the security and underlying collateral. If our judgment about an individual security changes in the future, we may ultimately record a credit loss after having originally concluded that one did not exist, which could have a material impact on our net income and financial position in future periods.

(e) Fixed income securities at December 31, 2016, by contractual maturity are shown below. MBS are included in the maturity tables using the estimated average life of each security. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

(f) We evaluate the alternative investments and tax credit investments included in our other investments portfolio to determine whether those investments are VIEs and if so, whether consolidation is required. A VIE is an entity that either has equity investors that lack certain essential characteristics of a controlling financial interest or lack sufficient funds to finance its own activities without financial support provided by other entities. We consider several significant factors in determining if our investments are VIEs and if we are the primary beneficiary, including whether we have: (i) the power to direct activities of the VIE; (ii) the ability to remove the decision maker of the VIE; (iii) the ability to participate in making decisions that are significant to the VIE; and (iv) the obligation to absorb losses and the right to receive benefits that could potentially be

significant to the VIE. We have determined that the investments in our other investment portfolio are VIEs, but that we are not the primary beneficiary and therefore, consolidation is not required.

The following table summarizes our other investment portfolio by strategy:

¹The maximum exposure to loss includes both the carry value of these investments and the related unfunded commitments. In addition, tax credits that have been previously recognized in Other securities are subject to the risk of recapture, which we do not consider significant.

The following is a description of our alternative investment strategies:

Our private equity strategy includes the following:


•	Primary Private Equity: This strategy makes private equity investments, primarily in established large and middle market companies across diverse industries globally.


•	Secondary Private Equity: This strategy purchases seasoned private equity funds from investors desiring liquidity prior to normal fund termination. Investments are made across all sectors of the private equity market, including leveraged buyouts ("LBO"), venture capital, distressed securities, mezzanine financing, real estate, and infrastructure.


•	Venture Capital: In general, these investments are made principally by investing in equity securities of privately-held corporations, for long-term capital appreciation. This strategy makes private equity investments in growth equity and buyout partnerships.

Our private credit strategy includes the following:


•	Middle Market Lending: This strategy provides privately negotiated loans to U.S. middle market companies. Typically, these are floating rate, senior secured loans diversified across industries. Loans can be made to private equity sponsor-backed companies or non-sponsored companies to finance LBOs, recapitalizations, and acquisitions.


•	Mezzanine Financing: This strategy provides privately negotiated fixed income securities, generally with an equity component, to LBO firms and private and publicly traded large, mid, and small-cap companies to finance LBOs, recapitalizations, and acquisitions.

•

Distressed Debt: This strategy makes direct and indirect investments in debt and equity securities of companies that are experiencing financial and/or operational distress. Investments include buying indebtedness of bankrupt or financially troubled companies, small balance loan portfolios, special situations and capital structure arbitrage trades, commercial real estate mortgages, and similar non-U.S. securities and debt obligations.

Our real assets strategy includes the following:

•

Energy & Power Generation: This strategy makes energy and power generation investments in cash flow generating infrastructure assets. Energy investments are made in a variety of industries including oil, natural gas, and coal. These investments are diversified across the energy supply chain and include assets in the exploration and production, pipeline, and refining sectors. Power generation includes investments in: (i) conventional power, such as natural gas and oil; (ii) renewable power, such as wind and solar; and (iii) electric transmission and distribution.


•	Real Estate: This strategy invests opportunistically in real estate in North America, Europe, and Asia via direct property ownership, joint ventures, mortgages, and investments in equity and debt instruments.

Our alternative investment strategies generally employ low or moderate levels of leverage and use hedging only to reduce foreign exchange or interest rate volatility. At this time, our alternative investment strategies do not include hedge funds. We cannot redeem our investments with the general partners of these investments; however, occasionally these partnerships can be traded on the secondary market. Once liquidation is triggered by clauses within the limited partnership agreements or at the funds’ stated end date, we will receive our final allocation of capital and any earned appreciation of the underlying investments, assuming we have not divested ourselves of our partnership interests prior to that time. We currently receive distributions from these alternative investments through the realization of the underlying investments in the limited partnerships. We anticipate that the general partners of these alternative investments will liquidate their underlying investment portfolios through 2030.

The following tables set forth summarized financial information for our other investments portfolio, including the portion not owned by us. The investments are carried under the equity method of accounting. The last line in the income statement information table below reflects our share of the aggregate income, which is the portion included in our Financial Statements. As the majority of these investments report results to us on a one quarter lag, the summarized financial statement information is as of, and for the 12-month period ended, September 30:

(h) We have pledged certain AFS fixed income securities as collateral related to our relationships with the Federal Home Loan Bank of Indianapolis ("FHLBI") and the Federal Home Loan Bank of New York ("FHLBNY"). In addition, certain securities were on deposit with various state and regulatory agencies at December 31, 2016 to comply with insurance laws. We retain all rights regarding securities pledged as collateral.

The majority of the OTTI charges in 2016 were on securities for which we had the intent to sell to facilitate our fixed income strategy change to more actively manage the portfolio to maximize after-tax income and total return, while maintaining a similar level of credit quality and duration risk. Charges in 2015 and 2014 related to equity securities for which we had the intent to sell in relation to a change in our high-dividend yield strategy, with the remaining charges relating to securities that we did not believe would recover in the near term.

(k) The components of net realized gains, excluding OTTI charges, were as follows:

Total net realized investment gains	$	3,562		31,537		37,703

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold. Proceeds from the sale of AFS securities were $1,046.1 million in 2016, $234.1 million in 2015, and $259.0 million in 2014.

Net realized gains in the table above were driven by the following:


•	2016: A repositioning of our equity portfolio partially offset by net losses in our AFS fixed income portfolio related to the change in our strategy to more actively manage this portfolio.


•	2015: A change in our dividend strategy from a quantitative, model-driven stock selection strategy to a fundamentally-based stock selection approach that incorporates an assessment of the sustainability and growth rate of a company's dividends and future cash flow.


•	2014: A quantitative rebalancing of our dividend yield strategy holdings within our equity portfolio.

Note 8. Reinsurance

Our Financial Statements reflect the effects of assumed and ceded reinsurance transactions. Assumed reinsurance refers to the acceptance of certain insurance risks that other insurance entities have underwritten. Ceded reinsurance involves transferring certain insurance risks (along with the related written and earned premiums) that we have underwritten to other insurance companies that agree to share these risks. The primary purpose of ceded reinsurance is to protect the Insurance Subsidiaries from potential losses in excess of the amount that we are prepared to accept. Our major treaties covering property, property catastrophe, and casualty business are excess of loss contracts. In addition, we have an intercompany quota share pooling arrangement and other minor quota share treaties.

As a Standard Commercial Lines and E&S Lines writer, we are required to participate in Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA"), which was extended by Congress to December 31, 2020. TRIPRA requires private insurers and the United States government to share the risk of loss on future acts of terrorism certified by the U.S. Secretary of the Treasury. Under TRIPRA, each participating insurer is responsible for paying a deductible of specified losses before federal assistance is available. This deductible is based on a percentage of the prior year’s applicable Standard Commercial Lines and E&S Lines premiums. In 2017, our deductible is approximately $304 million. For losses above the deductible, the federal government will pay 83% of losses to an industry limit of $100 billion, and the insurer retains 17%. The federal share of losses will be reduced by 1% each year to 80% by 2020.

The Insurance Subsidiaries remain liable to policyholders to the extent that any reinsurer becomes unable to meet their contractual obligations. We evaluate and monitor the financial condition of our reinsurers under voluntary reinsurance arrangements to minimize our exposure to significant losses from reinsurer insolvencies. On an ongoing basis, we review amounts outstanding, length of collection period, changes in reinsurer credit ratings, and other relevant factors to determine collectability of reinsurance recoverables. The allowance for uncollectible reinsurance recoverables was $5.5 million at December 31, 2016 and $5.7 million at December 31, 2015.

104

The following table represents our total reinsurance balances segregated by reinsurer to depict our concentration of risk throughout our reinsurance portfolio:

Note: Some amounts may not foot due to rounding.

Under our reinsurance arrangements, which are prospective in nature, reinsurance premiums ceded are recorded as prepaid reinsurance and amortized over the remaining contract period in proportion to the reinsurance protection provided, or recorded periodically, as per the terms of the contract, in a direct relationship to the gross premium recording. Reinsurance recoveries are recognized as gross losses are incurred.

Gross reserves for losses and loss expenses at end of year	$	3,691,719		3,517,728		3,477,870

Our net losses and loss expense reserves increased by $113.8 million in 2016, $60.8 million in 2015, and $97.0 million in 2014. The losses and loss expense reserves are net of anticipated recoveries for salvage and subrogation claims, which amounted to $64.9 million for 2016, $62.1 million for 2015, and $65.1 million for 2014. The changes in the net losses and loss expense reserves were the result of growth in exposures, particularly associated with our E&S Lines of business, anticipated loss trends, and normal reserve changes inherent in the uncertainty in establishing reserves for losses and loss expenses. As additional information is collected in the loss settlement process, reserves are adjusted accordingly. These adjustments are reflected in the Consolidated Statements of Income in the period in which such adjustments are identified. These changes could have a material impact on the results of operations of future periods when the adjustments are made.

In 2016, we experienced overall net favorable loss development of $65.8 million, compared to $69.0 million in 2015, and $59.3 million in 2014. The following table summarizes the prior year development by line of business:



(Favorable)/Unfavorable Prior Year Development
($ in millions)	2016			2015		2014
General Liability	$	(45.0	)	(51.0	)	(43.9	)

The prior accident year development during 2016 was favorable by $65.8 million, which included $69.0 million of net favorable casualty development and $3.2 million of unfavorable property development. The net favorable casualty reserve development was largely driven by the general liability line of business, including products liability and excess liability, and by the workers compensation line. Partially offsetting this net favorable development was the commercial auto line of business, which experienced $25.0 million of unfavorable casualty development in 2016. In addition, our E&S Lines experienced unfavorable casualty development of $6.0 million in 2016.

106

The majority of the 2016 net favorable development was attributable to accident years 2013 and prior, driven by the general liability and workers compensation lines of business. This net favorable development was partially offset by unfavorable development in accident years 2014 and 2015, which was attributable to our commercial auto and E&S Lines of business. The unfavorable development in our commercial auto line of business was driven primarily by bodily injury liability for accident years 2014 and 2015. The unfavorable development in accident year 2014 was driven by higher than expected severity, whereas accident year 2015 was driven by higher than expected frequency and severity.

The prior accident year development during 2015 was favorable by $69.0 million, which included $67.0 million of net favorable casualty development and $2.0 million of favorable property development. The net favorable casualty reserve development was largely driven by the general liability and workers compensation lines of business. For workers compensation, this was a significant change from 2014, during which period this line experienced no development. Our E&S Lines experienced unfavorable casualty development of $15.5 million in 2015.

The majority of the 2015 net favorable development was attributable to accident years 2009 through 2013, driven by general liability and workers compensation lines of business. This net favorable development was partially offset by unfavorable development in accident years 2012 through 2014, which was attributable to our E&S Lines.

The prior accident year development during 2014 was favorable by $59.3 million, which included $48.2 million of net favorable casualty development and $11.1 million of property development. The property development was primarily related to a prior year reinsurance recoverable. The net favorable casualty reserve development was largely driven by the general liability and personal automobile lines of business. Conversely, businessowners' policies and our E&S Lines experienced unfavorable emergence in 2014.

The majority of the 2014 net favorable development was attributable to accident years 2010 through 2012, although earlier accident years also developed favorably. The general liability, commercial automobile, and personal automobile lines of business all contributed to this development, partially offset by businessowners’ liability. The overall favorable development for accident years 2012 and prior was partially offset by unfavorable development in accident year 2013, which was largely attributable to commercial automobile liability, and partially E&S Lines casualty.

(b) Reserves established for liability insurance include exposure to asbestos and environmental claims. These claims have arisen primarily from insured exposures in municipal government, small non-manufacturing commercial risk, and homeowners policies. The emergence of these claims is slow and highly unpredictable. There are significant uncertainties in estimating our exposure to asbestos and environmental claims (for both case and IBNR reserves) resulting from lack of relevant historical data, the delayed and inconsistent reporting patterns associated with these claims, and uncertainty as to the number and identity of claimants and complex legal and coverage issues. Legal issues that arise in asbestos and environmental cases include federal or state venue, choice of law, causation, admissibility of evidence, allocation of damages and contribution among joint defendants, successor and predecessor liability, and whether direct action against insurers can be maintained. Coverage issues that arise in asbestos and environmental cases include the interpretation and application of policy exclusions, the determination and calculation of policy limits, the determination of the ultimate amount of a loss, the extent to which a loss is covered by a policy, if at all, the obligation of an insurer to defend a claim, and the extent to which a party can prove the existence of coverage. Courts have reached different and sometimes inconsistent conclusions on these legal and coverage issues. We do not discount to present value that portion of our losses and loss expense reserves expected to be paid in future periods.

The following table details our losses and loss expense reserves for various asbestos and environmental claims:



	2016
($ in millions)	Gross		Net
Asbestos	$	7.9	6.6
Landfill sites	12.8		8.1
Leaking underground storage tanks	9.3		8.0
Total	$	30.0	22.7

environmental losses. In addition, while certain alternative models can be applied, such models can produce significantly different results with small changes in assumptions. As a result, we do not calculate an asbestos and environmental loss range. Historically, our asbestos and environmental claims have been significantly lower in volume as, prior to the introduction of the absolute pollution exclusion endorsement in the mid-1980’s, we were primarily a personal lines carrier and therefore do not have broad exposure to asbestos and environmental claims. Additionally, we are the primary insurance carrier on the majority of these exposures, which provides more certainty in our reserve position compared to other insurance carriers.

The following table provides a roll forward of gross and net asbestos and environmental incurred losses and loss expenses and related reserves thereon:

(c) The following is information about incurred and paid claims development as of December 31, 2016, net of reinsurance, as well as cumulative claim frequency and the total of IBNR liabilities. During the experience period, we implemented a series of claims-related initiatives and claims management changes. These initiatives focused on claims handling and reserving, medical claims costs, and loss adjustment expenses. As a result of these initiatives, several historical patterns have changed and may no longer be appropriate to use as the sole basis for projections.

The information about incurred and paid claims development for the years ended December 31, 2007 to 2015 is presented as supplementary information.

Short-term Debt

(1) In January 2015, Selective Insurance Company of South Carolina ("SICSC") and Selective Insurance Company of the Southeast ("SICSE"), collectively referred to as the "Indiana Subsidiaries," borrowed $15 million in the aggregate from the FHLBI with an interest rate of 0.63%. The funds were used for general corporate purposes. We repaid this borrowing on July 22, 2016.

(2) In December 2011, the Indiana Subsidiaries borrowed $45 million in the aggregate from the FHLBI with an interest rate of 1.25%. The funds were loaned to the Parent for use in the acquisition of Mesa Underwriters Specialty Insurance Company ("MUSIC") on December 31, 2011. We repaid this borrowing in December 2016.

In addition to the above borrowings, the Parent's line of credit with Wells Fargo Bank, National Association, as administrative agent, and Branch Banking and Trust Company (BB&T) (referred to as our "Line of Credit"), was renewed effective December 1, 2015, with a borrowing capacity of $30 million, which can be increased to $50 million with the approval of both lending partners. Our Line of Credit expires on December 1, 2020, and has an interest rate, which varies and is based on, among other factors, the Parent’s debt ratings. There were no balances outstanding under our Line of Credit at December 31, 2016 or at any time during 2016.

Our Line of Credit agreement contains representations, warranties, and covenants that are customary for credit facilities of this type, including, without limitation, financial covenants under which we are obligated to maintain a minimum consolidated net worth, minimum combined statutory surplus, maximum ratio of consolidated debt to total capitalization, and covenants limiting our ability to: (i) merge or liquidate; (ii) incur debt or liens; (iii) dispose of assets; (iv) make investments and acquisitions; and (v) engage in transactions with affiliates.

116

The table below outlines information regarding certain of the covenants in the Line of Credit:



	Required as of	Actual as of
	December 31, 2016	December 31, 2016
Consolidated net worth	Not less than $1.1 billion	$1.5 billion
Statutory surplus	Not less than $750 million	$1.6 billion
Debt-to-capitalization ratio¹	Not to exceed 35%	22.5%
A.M. Best financial strength rating	Minimum of A-	A

¹Calculated in accordance with the Line of Credit agreement.

In addition to the above requirements, the Line of Credit agreement contains a cross-default provision that provides that the Line of Credit will be in default if we fail to comply with any condition, covenant, or agreement (including payment of principal and interest when due on any debt with an aggregate principal amount of at least $20 million), which causes or permits the acceleration of principal.

Refer to "Financial Condition, Liquidity, and Capital Resources" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations." for further discussion regarding limitations on aggregate borrowings by the FHLBI and FHLBNY permitted by our Line of Credit.

Long-term Debt

(3) In the first quarter of 2009, the Indiana Subsidiaries joined, and invested in, the FHLBI, which provides them with access to additional liquidity. The Indiana Subsidiaries’ aggregate investment in the FHLBI was $2.8 million at December 31, 2016 and $2.8 million at December 31, 2015. Our investment provides us the ability to borrow approximately 20 times the total amount of the FHLBI common stock purchased with additional collateral, at comparatively low borrowing rates.

In December 2016, the Indiana Subsidiaries borrowed $60 million from the FHLBI at an interest rate of 3.03%. The principal amount of this borrowing is due on December 16, 2026. $45 million of the proceeds were used to repay the then outstanding $45 million borrowing from the FHLBI and the remaining $15 million was used for general corporate purposes.

All borrowings from the FHLBI require security. For information on investments that are pledged as collateral for these borrowings, see Note 5. "Investments" above.

(4) In the fourth quarter of 2015, SICA and Selective Insurance Company of New York ("SICNY") joined, and invested in, the FHLBNY, which provides them with access to additional liquidity. The aggregate investment for both subsidiaries was $2.8 million at December 31, 2016 and $0.5 million at December 31, 2015. Our investment provides us the ability to borrow approximately 20 times the total amount of the FHLBNY common stock purchased with additional collateral, at comparatively low borrowing rates. In August 2016, SICA borrowed $25 million from the FHLBNY. The unpaid principal amount accrues interest of 1.56%. The principal amount is due on August 16, 2021.

All borrowings from the FHLBNY require security. For information on investments that are pledged as collateral for these borrowings, see Note 5. "Investments" above.

(5) In July 2016, SICA borrowed $25 million from the FHLBNY. The unpaid principal amount accrues interest of 1.61%. The principal amount is due on July 21, 2021.

(6) In February 2013, we issued $185 million of 5.875% Senior Notes due 2043. The notes are callable by us on or after February 8, 2018, at a price equal to 100% of their principal outstanding amount, plus accrued and unpaid interest to, but excluding, the date of redemption. A portion of the proceeds from this debt issuance was used to fully redeem the $100 million aggregate principal amount of our 7.5% Junior Subordinated Notes due 2066. Of the remaining net proceeds, $57.1 million was used to make capital contributions to the Insurance Subsidiaries, while the balance was used for general corporate purposes. There are no financial debt covenants to which we are required to comply in regards to these Senior Notes.

117

(7) In November 2005, we issued $100 million of 6.70% Senior Notes due 2035. These notes were issued at a discount of $0.7 million resulting in an effective yield of 6.754%. Net proceeds of approximately $50 million were used to fund an irrevocable trust to provide for certain payment obligations in respect of our outstanding debt. The remainder of the proceeds was used for general corporate purposes. The agreements covering these notes contain a standard default cross-acceleration provision that provides the 6.70% Senior Notes will enter a state of default upon the failure to pay principal when due or upon any event or condition that results in an acceleration of principal of any other debt instrument in excess of $10 million that we have outstanding concurrently with the 6.70% Senior Notes. There are no financial debt covenants to which we are required to comply in regards to these notes.

(8) In November 2004, we issued $50 million of 7.25% Senior Notes due 2034. These notes were issued at a discount of $0.1 million, resulting in an effective yield of 7.27%. We contributed $25 million of the bond proceeds to the Insurance Subsidiaries as capital. The remainder of the proceeds was used for general corporate purposes. The agreements covering these notes contain a standard default cross-acceleration provision that provides the 7.25% Senior Notes will enter a state of default upon the failure to pay principal when due or upon any event or condition that results in an acceleration of principal of any other debt instrument in excess of $10 million that we have outstanding concurrently with the 7.25% Senior Notes. There are no financial debt covenants to which we are required to comply in regards to these notes.

Note 11. Segment Information

The disaggregated results of our four reportable segments are used by senior management to manage our operations. These reportable segments are evaluated as follows:


•	Our Standard Commercial Lines, Standard Personal Lines, and E&S Lines are evaluated based on statutory underwriting results (net premiums earned, incurred losses and loss expenses, policyholders dividends, policy acquisition costs, and other underwriting expenses), and statutory combined ratios.


•	Our Investments segment is evaluated based on after-tax net investment income and net realized gains and losses.

In computing the results of each segment, we do not make adjustments for interest expense or net general corporate expenses. While we do not fully allocate taxes to all segments, we do allocate taxes to our investments segment as we manage that segment on after-tax results. We do not maintain separate investment portfolios for the segments and therefore, do not allocate assets to the segments.

Our combined insurance segments are subject to certain geographic concentrations, particularly in the Northeast and Mid-Atlantic regions of the country. In 2016, approximately 20% of NPW were related to insurance policies written in New Jersey.

The goodwill balance of $7.8 million at both December 31, 2016 and 2015 relates to our Standard Commercial Lines reporting unit.

After considering all evidence, both positive and negative, with respect to our federal tax loss carryback availability, expected levels of pre-tax financial statement income, and federal taxable income, we believe it is more likely than not that the existing deductible temporary differences will reverse during periods in which we generate net federal taxable income or have adequate

121

federal carryback availability. As a result, we have no valuation allowance recognized for federal deferred tax assets at December 31, 2016 or 2015.

As of December 31, 2016, we had federal tax net operating loss ("NOL") carryforwards of $2.2 million. These NOLs, which are subject to an annual limitation of $1.9 million, will expire between 2030 and 2031 as follows:



($ in thousands)	Gross NOL		Tax Effected NOL
2030	$	2,124	744
2031	79		28
Total NOL carryforwards	$	2,203	772

Stockholders' equity reflects tax benefits related to compensation expense deductions for share-based compensation awards of $23.8 million at December 31, 2016, $22.0 million at December 31, 2015, and $20.2 million at December 31, 2014.

We have analyzed our tax positions in all open tax years, which as of December 31, 2016 were 2013 through 2015. The 2013 tax year is currently under audit. We do not expect any material adjustments to arise out of the 2013 audit. We do not have unrecognized tax expense or benefit as of December 31, 2016.

We believe our tax positions will more likely than not be sustained upon examination, including related appeals or litigation. In the event we had a tax position that did not meet the more likely than not criteria, any tax, interest, and penalties incurred related to such a position would be reflected in "Total federal income tax expense" on our Consolidated Statements of Income.

Note 14. Retirement Plans

(a) Selective Insurance Retirement Savings Plan (“Retirement Savings Plan”)

SICA offers a voluntary defined contribution 401(k) plan, which is available to most of our employees and is a tax-qualified retirement plan subject to the Employee Retirement Income Security Act of 1974 ("ERISA"). Expense recorded for this plan was $15.0 million in 2016, $14.1 million in 2015, and $13.4 million in 2014.

(b) Deferred Compensation Plan

SICA offers a nonqualified deferred compensation plan ("Deferred Compensation Plan") to a group of management or highly compensated employees as a method of recognizing and retaining such employees. The Deferred Compensation Plan provides these employees the opportunity to elect to defer receipt of specified portions of compensation and to have such deferred amounts deemed to be invested in specified investment options. In addition to the employee deferrals, SICA may choose to make matching contributions to some or all of the participants in this plan to the extent the participant did not receive the maximum matching or non-elective contributions permissible under the Retirement Savings Plan due to limitations under the Internal Revenue Code or the Retirement Savings Plan. Expense recorded for these contributions was $0.3 million in 2016 and $0.2 million in both 2015 and 2014.

SICA's primary pension plan is the Retirement Income Plan for Selective Insurance Company of America (the "Pension Plan"). This qualified, noncontributory defined benefit plan is closed to new entrants and existing participants ceased accruing benefits after March 31, 2016.

In addition to the Pension Plan, SICA also sponsors the Supplemental Excess Retirement Plan (the "Excess Plan") and a life insurance benefit plan (the "Retirement Life Plan"). Both of these plans are closed to new entrants and participants in the Excess Plan ceased accruing benefits after March 31, 2016. The Retirement Life Plan does not accrue benefits and this plan applies only to retirees who terminated employment with SICA on or before March 31, 2009. These are both unfunded plans with benefit obligations as of December 31, 2016 and December 31, 2015 of $9.1 million and $8.5 million, respectively, for the Excess Plan and $6.3 million and $6.0 million, respectively, for the Retiree Life Plan. Expense recorded for the Excess Plan was $0.5 million in 2016, $0.8 million in 2015, and $0.6 million in 2014. Expense recorded for the Retiree Life Plan was $0.3 million in 2016 and 2015, and $0.4 million in 2014.

Total recognized in net periodic benefit cost and other comprehensive income	$	7,990		3,489		55,424

123

The estimated net actuarial loss for the Pension Plan that will be amortized from AOCI into net periodic benefit cost during the 2017 fiscal year is $1.9 million. This is lower than the $6.3 million amortized in 2016 due to a change in the amortization period for the net actuarial loss. Historically, the amortization period was the average remaining service life of the active participants. However, as the Pension Plan is no longer accruing service benefits, the amortization period has changed to the average remaining life expectancy of plan participants.



	Pension Plan
	2016		2015	2014
Weighted-Average Expense Assumptions for the years ended December 31:
Discount rate	4.69	%	4.29	5.16
Expected return on plan assets	6.37		6.27	6.92
Rate of compensation increase¹	—		4.00	4.00

¹This assumption was 4.00% through March 31, 2016, the date after which benefits ceased accruing for all participants of the Pension Plan.

Our latest measurement date was December 31, 2016 and we decreased our expected return on plan assets to 6.24%, reflecting the current interest rate environment.

When determining the most appropriate discount rate to be used in the valuation, we consider, among other factors, our expected payout patterns of the Pension Plan's obligations as well as our investment strategy and we ultimately select the rate that we believe best represents our estimate of the inherent interest rate at which our pension and post-retirement life benefits can be effectively settled. Effective January 1, 2016, the approach used to calculate the service and interest components of net periodic benefit cost for benefit plans was changed to provide a more precise measurement of service and interest costs. Prior to 2016, we calculated these service and interest components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. Beginning in 2016, we elected to utilize an approach that discounts the individual expected cash flows using the applicable spot rates derived from the yield curve over the projected cash flow period. We have accounted for this change prospectively as a change in accounting estimate. The weighted average discount rate used to determine 2017 interest cost is 3.83%.

Plan Assets

Assets of the Pension Plan are invested to ensure that principal is preserved and enhanced over time. Our return objective is to exceed the returns of the plan's policy benchmark, which is the return the plan would have earned if the assets were invested according to the target asset class weightings and earned index returns shown below. In 2017, we will continue to phase in adjustments to the asset allocation to steadily close the gap between the duration of the assets and the duration of the liabilities, provided certain improved funding targets are achieved.

The Pension Plan’s equity investments may not contain investments in any one security greater than 8% of the portfolio value without notification to our management investment committee, nor have more than 5% of the outstanding shares of any one corporation or other entity. The use of derivative instruments is permitted under certain circumstances, but shall not be used for unrelated speculative hedging or to apply leverage to portfolio positions. Within the alternative investments portfolio, some leverage is permitted as defined and limited by the partnership agreements.

The plan’s target ranges, as well as the actual weighted average asset allocation by asset class, at December 31 were as follows:



	2016				2015
	Target Ranges		Actual Percentage		Actual Percentage
Long duration fixed income	40%-100%		53	%	60	%
Global equity	0%-40%		33	%	36	%
Alternatives & other return seeking assets¹	0%-30%		6	%	3	%
Cash and short-term investments	0%-5%		8	%	1	%
Total	—	%	100	%	100	%

¹Includes limited partnerships.

At December 31, 2016, the Pension Plan's allocation to cash and short-term investments was slightly above the targeted range, as we were analyzing the most effective deployment of these balances considering current market conditions.

The Pension Plan had no investments in the Parent’s common stock as of December 31, 2016 or 2015.

124

The techniques used to determine the fair value of the Pension Plan's invested assets are as follows:


•	Short-term investments are carried at cost, which approximates fair value. Given that these investments are listed on active exchanges, coupled with their liquid nature, these investments are classified as Level 1 in the fair value hierarchy.

•

The deposit administration contract is carried at cost, which approximates fair value. Given the liquid nature of the underlying investments in overnight cash deposits and other short-term duration products, we have determined that a correlation exists between the deposit administration contract and other short-term investments, such as money market funds. As such, this investment is classified as Level 2 in the fair value hierarchy.


•	The long-duration fixed income mutual funds utilize a market approach wherein the quoted prices in the active market for identical assets are used. All of the mutual funds are traded in active markets at their net asset value per share. These investments are classified as Level 1 in the fair value hierarchy.


•	The investments in global equity collective investment funds and in private equity limited partnerships are valued utilizing net asset value as a practical expedient for fair value. These investments are not classified in the fair value hierarchy.

For discussion regarding the levels within the fair value hierarchy, see Note 2. "Summary of Significant Accounting Policies."

In addition, refer to Note 5. "Investments" for discussion regarding the limited partnership investment strategies, excluding the middle market lending strategy, as these investments are not part of the Pension Plan.

The following tables provide quantitative disclosures of the Pension Plan’s invested assets that are measured at fair value on a recurring basis:

•	The Employee Stock Purchase Plan (2009) ("ESPP"); and


•	The Amended and Restated Stock Purchase Plan for Independent Insurance Agencies (the "Agent Plan").

126

The following table provides information regarding the approval of these plans:



Plan	Approvals
Stock Plan	Approved effective as of May 1, 2014 by stockholders on April 23, 2014.
Cash Plan	Approved effective April 1, 2005 by stockholders on April 27, 2005. Most recently amended and restated plan was approved effective May 1, 2014 by stockholders on April 23, 2014.
ESPP	Approved by stockholders on April 29, 2009 effective July 1, 2009.
Agent Plan	Approved by stockholders on April 26, 2006. Most recently amended and restated plan was approved on December 13, 2016 by the Parent's Board of Directors' Salary and Employee Benefits Committee. The amendment was effective February 1, 2017.

The types of awards that can be issued under each of these plans are as follows:



Plan	Types of Share-Based Payments Issued
Stock Plan	Qualified and nonqualified stock options, stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), stock grants, and other awards valued in whole or in part by reference to the Parent's common stock. The maximum exercise period for an option grant under this plan is 10 years from the date of the grant. Dividend equivalent units ("DEUs") are earned during the vesting period on RSU grants. The DEUs are reinvested in the Parent's common stock at fair value on each dividend payment date. The requisite service period for grants to employees under this plan is the lesser of: (i) the stated vested date, which is typically three years from issuance; or (ii) the date the employee becomes eligible to retire.
Cash Plan	Cash incentive units (“CIUs”). The initial dollar value of each CIU will be adjusted to reflect the percentage increase or decrease in the total shareholder return on the Parent's common stock over a specified performance period. In addition, for certain grants, the number of CIUs granted will be increased or decreased to reflect our performance on specified performance indicators as compared to targeted peer companies. The requisite service period for grants under this plan is the lesser of: (i) the stated vested date, which is typically three years from issuance; or (ii) the date the employee becomes eligible to retire.
ESPP	Enables employees to purchase shares of the Parent’s common stock. The purchase price is the lower of: (i) 85% of the closing market price at the time the option is granted; or (ii) 85% of the closing price at the time the option is exercised. Shares are generally issued on June 30 and December 31 of each year.
Agent Plan	Quarterly offerings to purchase the Parent's common stock at a 10% discount with a one year restricted period during which the shares purchased cannot be sold or transferred. Only our independent retail insurance agencies and wholesale general agencies, and certain eligible persons associated with the agencies, are eligible to participate in this plan.

Shares authorized and available for issuance as of December 31, 2016 are as follows:

RSU Transactions

A summary of the RSU transactions under our share-based payment plans is as follows:



	Number of Shares		Weighted Average Grant Date Fair Value
Unvested RSU awards at December 31, 2015	1,018,530		$	22.55

That expense is expected to be recognized over a weighted-average period of 1.8 years. The total intrinsic value of RSUs vested was $12.6 million for 2016, $10.3 million for 2015, and $8.5 million for 2014. In connection with vested RSUs, the total value of the DEU shares that vested was $0.7 million during each of 2016, 2015, and 2014.

Option Transactions

A summary of the stock option transactions under our share-based payment plans is as follows:



	Number of Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life in Years	Aggregate Intrinsic Value ($ in thousands)
Outstanding at December 31, 2015	493,428		$	17.84
Granted in 2016	—		—
Exercised in 2016	(138,037	)	20.33

The total intrinsic value of options exercised was $2.3 million during 2016, $2.2 million in 2015, and $0.8 million in 2014.

CIU Transactions

The liability recorded in connection with our Cash Plan was $32.0 million at December 31, 2016 and $26.5 million at December 31, 2015. The remaining cost associated with the CIUs is expected to be recognized over a weighted average period of 1.2 years. The CIU payments made were $14.3 million in 2016, $10.2 million in 2015, and $9.0 million in 2014.

ESPP and Agent Plan Transactions

A summary of ESPP and Agent Plan share issuances is as follows:



	2016	2015	2014
ESPP Issuances	88,432	100,944	106,832
Agent Plan Issuances	69,867	82,142	78,724

Fair Value Measurements

The grant date fair value of RSUs is based on the market price of our common stock on the grant date, adjusted for the present value of our expected dividend payments. The expense recognized for share-based awards is based on the number of shares or units expected to be issued at the end of the performance period and the grant date fair value.

128

The grant date fair value of each option award is estimated using the Black Scholes option valuation model ("Black Scholes"). The following are the significant assumptions used in applying Black Scholes: (i) the risk-free interest rate, which is the implied yield currently available on U.S. Treasury zero-coupon issues with an equal remaining term; (ii) the expected term, which is based on historical experience of similar awards; (iii) the dividend yield, which is determined by dividing the expected per share dividend during the coming year by the grant date stock price; and (iv) the expected volatility, which is based on the volatility of the Parent's stock price over a historical period comparable to the expected term. In applying Black Scholes, we use the weighted average assumptions illustrated in the following table:



	ESPP
	2016		2015	2014
Risk-free interest rate	0.47	%	0.10	0.07
Expected term	6 months		6 months	6 months
Dividend yield	1.7	%	2.0	2.0
Expected volatility	31	%	20	21

The weighted-average fair value of options and stock per share, including RSUs granted for the Parent's stock plans, during 2016, 2015, and 2014 was as follows:



	2016		2015	2014
RSUs	$	32.53	25.22	21.58
ESPP:
Six month option	2.63		1.26	1.24
Discount of grant date market value	5.23		4.16	3.87
Total ESPP	7.86		5.42	5.11
Agent Plan:
Discount of grant date market value	3.79		2.94	2.42

The fair value of the CIU liability is remeasured at each reporting period through the settlement date of the awards, which is three years from the date of grant based on an amount expected to be paid. A Monte Carlo simulation is performed to approximate the projected fair value of the CIUs that, in accordance with the Cash Plan, is adjusted to reflect our performance on specified indicators as compared to targeted peer companies.

Note 16. Related Party Transactions

William M. Rue, a Director of the Parent, is Chairman of, and owns more than 10% of the equity of, Chas. E. Rue & Son, Inc., t/a Rue Insurance, a general independent retail insurance agency ("Rue Insurance"). Rue Insurance is an appointed distribution partner of the Insurance Subsidiaries on terms and conditions similar to those of our other distribution partners and includes the right to participate in the Agent Plan. Mr. Rue’s son is President, and an employee, of Rue Insurance and Mr. Rue’s daughter is an employee of Rue Insurance. Our relationship with Rue Insurance has existed since 1928.

Rue Insurance placed insurance policies with the Insurance Subsidiaries for its customers and itself. Direct premiums written associated with these policies were $10.4 million in 2016, $9.6 million in 2015, and $9.0 million in 2014. In return, the Insurance Subsidiaries paid standard market commissions to Rue Insurance of $2.1 million in 2016, $1.7 million in 2015, and $1.6 million in 2014 including supplemental commissions. Amounts due to Rue Insurance at December 31, 2016 and December 31, 2015 were $0.7 million and $0.6 million, respectively.

In 2005, we established a private foundation, now named The Selective Insurance Group Foundation (the "Foundation"), under Section 501(c)(3) of the Internal Revenue Code. The Board of Directors of the Foundation is comprised of some of the Parent's officers. We made no contributions to the Foundation in 2016. We made contributions to the Foundation in the amount of $1.0 million in 2015 and $0.8 million in 2014.

Note 17. Commitments and Contingencies

(a) We purchase annuities from life insurance companies to fulfill obligations under claim settlements that provide for periodic future payments to claimants. As of December 31, 2016, we had purchased such annuities with a present value of $17.9 million for settlement of claims on a structured basis for which we are contingently liable. To our knowledge, there are no material defaults from any of the issuers of such annuities.

(b) We have various operating leases for office space, equipment, and fleet vehicles. Such lease agreements, which expire at various times, are generally renewed or replaced by similar leases. Rental expense under these leases amounted to $17.3 million in 2016, $17.4 million in 2015, and $15.6 million in 2014. We also lease computer hardware and software under capital lease agreements expiring at various dates through 2019. See item (p) of Note 2. "Summary of Significant Accounting Policies" in this Form 10-K for information on our accounting policy regarding leases.

In addition, certain of these leases are non-cancelable, and liability for payment will continue even though the leased asset may no longer be in use. At December 31, 2016, the total future minimum rental commitments under non-cancelable leases were as follows:



($ in millions)	Capital Leases		Operating Leases	Total
2017	$	4.0	9.1	13.1
2018	2.2		7.7	9.9
2019	0.1		5.6	5.7
2020	—		4.4	4.4
2021	—		2.9	2.9
After 2021	—		4.7	4.7
Total minimum payment required	$	6.3	34.4	40.7

(c) At December 31, 2016, we have contractual obligations that expire at various dates through 2030 to invest up to an additional $143.7 million in alternative and other investments. There is no certainty that any such additional investment will be required. For additional information regarding these investments, see item (f) of Note 5. "Investments" in this Form 10-K.

Note 18. Litigation

From time to time, our Insurance Subsidiaries also are named as defendants in other legal actions, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such putative class actions have alleged, for example, improper reimbursement of medical providers paid under workers compensation and personal and commercial automobile insurance policies. Similarly, our Insurance Subsidiaries are also named from time-to-time in individual actions seeking extra-contractual damages, punitive damages, or penalties, some of which allege bad faith in the handling of insurance claims. We believe that we have valid defenses to these cases. We expect that any potential ultimate liability in any such lawsuit will not be material to our consolidated financial condition, after consideration of provisions made for estimated losses. Nonetheless, given the inherent unpredictability of litigation and the large or indeterminate amounts sought in certain of these actions, an adverse outcome in certain matters could possibly have a material adverse effect on our consolidated results of operations or cash flows in particular quarterly or annual periods.

As of December 31, 2016, we do not believe the Company was involved in any legal action that could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

Note 19. Statutory Financial Information, Capital Requirements, and Restrictions on Dividends and Transfers of Funds

(a) Statutory Financial Information

The Insurance Subsidiaries prepare their statutory financial statements in accordance with accounting principles prescribed or permitted by the various state insurance departments of domicile. Prescribed statutory accounting principles include state laws, regulations, and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners (“NAIC"). Permitted statutory accounting principles encompass all accounting principles that are not prescribed; such principles differ from state to state, may differ from company to company within a state and may change in the future. The Insurance Subsidiaries do not utilize any permitted statutory accounting principles that materially affect the determination of statutory surplus, statutory net income, or risk-based capital (“RBC”). As of December 31, 2016, the various state insurance departments of domicile have adopted the March 2016 version of the NAIC Accounting Practices and Procedures manual in its entirety, as a component of prescribed or permitted practices.

The following table provides statutory data for each of our Insurance Subsidiaries:



	State of Domicile	Unassigned Surplus			Statutory Surplus		Statutory Net Income
($ in millions)		2016		2015	2016	2015	2016	2015	2014
SICA	New Jersey	$	414.4	366.6	568.6	520.8	72.2	69.6	83.9

Total		$	1,048.2	890.7	1,583.8	1,426.3	202.3	195.8	190.3

(b) Capital Requirements

The Insurance Subsidiaries are required to maintain certain minimum amounts of statutory surplus to satisfy the requirements of their various state insurance departments of domicile. RBC requirements for property and casualty insurance companies are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policyholders. The Insurance Subsidiaries' combined total adjusted capital exceeded the authorized control level RBC, as defined by the NAIC based on their 2016 statutory financial statements. In addition to statutory capital requirements, we are impacted by various rating agency requirements related to certain rating levels. These required capital levels may be more than statutory requirements.

Our ability to declare and pay dividends on the Parent's common stock is dependent on liquidity at the Parent coupled with the ability of the Insurance Subsidiaries to declare and pay dividends, if necessary, and/or the availability of other sources of liquidity to the Parent. As of December 31, 2016, the Parent had an aggregate of $91.7 million in investments and cash available to fund future dividends and interest payments. These amounts are not subject to any regulatory restrictions other than standard state insolvency restrictions, whereas our consolidated retained earnings of $1.5 billion is predominately restricted due to the regulation associated with our Insurance Subsidiaries. In 2017, the Insurance Subsidiaries have the ability to provide for $192.7 million in annual dividends to the Parent; however, as regulated entities, these dividends are subject to certain restrictions, which are further discussed below. The Parent also has available to it other potential sources of liquidity, such as: (i) borrowings from our Indiana Subsidiaries; (ii) debt issuances; (iii) common stock issuances; and (iv) borrowings under our Line of Credit. Borrowings from our Indiana Subsidiaries are governed by approved intercompany lending agreements with the Parent that provide for additional capacity of $68.6 million as of December 31, 2016, after considering that borrowings under these lending agreements are restricted to 10% of the admitted assets of these respective subsidiaries. For additional information regarding the Parent's Line of Credit, refer to "Financial Condition, Liquidity, and Capital Resources" in Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations.” of this Form 10-K. For additional restrictions on the Parent's debt, see Note 10. "Indebtedness" in this Form 10-K.

131

Insurance Subsidiaries Dividend Restrictions

As noted above, the restriction on our net assets and retained earnings is predominantly driven by our Insurance Subsidiaries' ability to pay dividends to the Parent under applicable law and regulations. Under the insurance laws of the domiciliary states of the Insurance Subsidiaries, New Jersey, Indiana, and New York, an insurer can potentially make an ordinary dividend payment if its statutory surplus following such dividend is reasonable in relation to its outstanding liabilities, is adequate to its financial needs, and the dividend does not exceed the insurer's unassigned surplus. In general, New Jersey defines an ordinary dividend as a dividend whose fair market value, together with other dividends made within the preceding 12 months, is less than the greater of 10% of the insurer's statutory surplus as of the preceding December 31, or the insurer's net income (excluding capital gains) for the 12-month period ending on the preceding December 31. Indiana's ordinary dividend calculation differs from New Jersey's, in that it is the lessor of 10% of the insurer's statutory surplus, or the insurer's net income. Indiana's net income is computed by subtracting the amount of dividends paid in the first and second preceding calendar years from the aggregate net income (excluding capital gains), of the second and third preceding calendar years.

In general, New York defines an ordinary dividend as a dividend whose fair market value, together with other dividends made within the preceding 12 months, is less than the lesser of 10% of the insurer's statutory surplus, or 100% of adjusted net investment income. New Jersey and Indiana require notice of the declaration of any ordinary dividend distribution. During the notice period, the relevant state regulatory authority may disallow all or part of the proposed dividend if it determines that the dividend is not appropriate given the above considerations. New York does not require notice of ordinary dividends. Dividend payments exceeding ordinary dividends are referred to as extraordinary dividends and require review and approval by the applicable domiciliary insurance regulatory authority prior to payment.

The following table provides quantitative data regarding all Insurance Subsidiaries' dividends paid to the Parent in 2016 for debt service, shareholder dividends, and general operating purposes:



Dividends		Twelve Months ended December 31, 2016

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are: (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act; and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) is a process designed by, or under the supervision of, a company's principal executive and principal financial officers and effected by the Board, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:


•	Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;


•	Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and


•	Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework ("COSO Framework") in 2013.

Based on this assessment, our management believes that, as of December 31, 2016, our internal control over financial reporting is effective.

No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during the fourth quarter of 2016 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Selective Insurance Group, Inc.:

We have audited Selective Insurance Group, Inc. and its subsidiaries’ (the “Company”) internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Selective Insurance Group, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Selective Insurance Group, Inc. and its subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Selective Insurance Group, Inc. and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016, and our report dated February 21, 2017 expressed an unqualified opinion on those consolidated financial statements.
