CNA FINANCIAL CORPORATION

CNA Financial Corporation (together with its subsidiaries, “CNA”) was incorporated in 1967 and is an insurance holding company. CNA’s property and casualty and remaining life & group insurance operations are primarily conducted by Continental Casualty Company (“CCC”), incorporated in 1897, and The Continental Insurance Company (“CIC”), organized in 1853, and certain other affiliates. CIC became a subsidiary of CNA in 1995 as a result of the acquisition of The Continental Corporation (“Continental”). CNA accounted for 67.8%, 67.7% and 68.0% of our consolidated total revenue for the years ended December 31, 2015, 2014 and 2013.

CNA’s insurance products primarily include commercial property and casualty coverages, including surety. CNA’s services include risk management, information services, warranty and claims administration. CNA’s products and services are primarily marketed through independent agents, brokers and managing general underwriters to a wide variety of customers, including small, medium and large businesses, insurance companies, associations, professionals and other groups.

CNA’s property and casualty field structure consists of 49 underwriting locations across the United States. In addition, there are five centralized processing operations which handle policy processing, billing and collection activities and also act as call centers to optimize service. The claims structure consists of two regional claim centers designed to efficiently handle the high volume of low severity claims including property damage, liability and workers’ compensation medical only claims, and 16 principal claim offices handling the more complex claims. CNA also has a presence in Canada, Europe and Singapore consisting of 19 branch operations and access to business placed at Lloyd’s of London (“Lloyd’s”) through Hardy Underwriting Bermuda Limited (“Hardy”).

Direct Written Premiums by Geographic Concentration

Set forth below is the distribution of CNA’s direct written premiums by geographic concentration.

Approximately 8.0%, 8.8%, and 9.0% of CNA’s direct written premiums were derived from outside of the United States for the years ended December 31, 2015, 2014 and 2013.

Property and Casualty Claim and Claim Adjustment Expenses

The following loss reserve development table illustrates the change over time of reserves established for property and casualty claim and claim adjustment expenses at the end of the preceding ten calendar years for CNA’s property and casualty insurance companies. The first section shows the reserves as originally reported at the end of the stated year. The second section, reading down, shows the cumulative amounts paid as of the end of successive years with respect to the originally reported reserve liability. The third section, reading down, shows re-estimates of the originally recorded reserves as of the end of each successive year, which is the result of CNA’s property and casualty insurance subsidiaries’ expanded awareness of additional facts and circumstances that pertain to the unsettled claims. The last section compares the latest re-estimated reserves to the reserves originally established, and indicates whether the original reserves were adequate or inadequate to cover the estimated costs of unsettled claims.

Investments

Please read Item 7, MD&A – Investments and Notes 1, 3 and 4 of the Notes to Consolidated Financial Statements, included under Item 8.

Other

Competition: The property and casualty insurance industry is highly competitive both as to rate and service. CNA competes with a large number of stock and mutual insurance companies and other entities for both distributors and customers. Insurers compete on the basis of factors including products, price, services, ratings and financial strength. CNA must continuously allocate resources to refine and improve its insurance products and services.

There are approximately 2,700 individual companies that sell property and casualty insurance in the United States. Based on 2014 statutory net written premiums, CNA is the eighth largest commercial insurance writer and the 14th largest property and casualty insurance organization in the United States.

Regulation: The insurance industry is subject to comprehensive and detailed regulation and supervision. Regulatory oversight by applicable agencies is exercised through review of submitted filings and information, examinations (both financial and market conduct), direct inquiries and interviews. Each domestic and foreign jurisdiction has established supervisory agencies with broad administrative powers relative to licensing insurers and agents, approving policy forms, establishing reserve requirements, prescribing the form and content of statutory financial reports and regulating capital adequacy and the type, quality and amount of investments permitted. Such regulatory powers also extend to premium rate regulations, which require that rates not be excessive, inadequate or unfairly discriminatory, governance requirements and risk assessment practice and disclosure. In addition to regulation of dividends by insurance subsidiaries, intercompany transfers of assets may be subject to prior notice or approval by insurance regulators, depending on the size of such transfers and payments in relation to the financial position of the insurance subsidiaries making the transfer or payment.

Domestic insurers are also required by state insurance regulators to provide coverage to insureds who would not otherwise be considered eligible by the insurers. Each state dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. CNA’s share of these involuntary risks is mandatory and generally a function of its respective share of the voluntary market by line of insurance in each state.

Further, domestic insurance companies are subject to state guaranty fund and other insurance-related assessments. Guaranty funds are governed by state insurance guaranty associations which levy assessments to meet the funding needs of insolvent insurer estates. Other insurance-related assessments are generally levied by state agencies to fund various organizations including disaster relief funds, rating bureaus, insurance departments, and workers’ compensation second injury funds, or by industry organizations that assist in the statistical analysis and ratemaking process and CNA has the ability to recoup certain of these assessments from policyholders.

As CNA’s insurance operations are conducted in a multitude of both domestic and foreign jurisdictions, CNA is subject to a number of regulatory agency requirements in respect of a portion, or all, of its operations. These include, but are not limited to, the State of Illinois Department of Insurance (which is CNA’s global group-wide supervisor), the U.K. Prudential Regulatory Authority and Financial Conduct Authority, the Bermuda Monetary Authority and the Office of Superintendent of Financial Institutions in Canada.

Hardy is also supervised by the Council of Lloyd’s, which is the franchisor for all Lloyd’s operations. The Council of Lloyd’s has wide discretionary powers to regulate Lloyd’s underwriting, such as establishing the capital requirements for syndicate participation. In addition, the annual business plans of each syndicate are subject to the review and approval of the Lloyd’s Franchise Board, which is responsible for business planning and monitoring for all syndicates.

Table of Contents

Effective January 1, 2016, the European Union’s executive body, the European Commission, implemented new capital adequacy and risk management regulations, Solvency II, that apply to CNA’s European operations. Additionally, the International Association of Insurance Supervisors (“IAIS”) continues to consider regulatory proposals addressing group supervision, capital requirements and enterprise risk management. The U.S. Federal Reserve, the U.S. Federal Insurance Office and the National Association of Insurance Commissioners are working with other global regulators to define such proposals. It is not currently clear to what extent the IAIS activities will impact CNA as any final proposal would ultimately need to be legislated or regulated by each individual country or state.

Although the federal government does not currently directly regulate the business of insurance, federal legislative and regulatory initiatives can impact the insurance industry. These initiatives and legislation include proposals relating to potential federal oversight of certain insurers; terrorism and natural catastrophe exposures; cybersecurity risk management; federal financial services reforms; and certain tax reforms. The Terrorism Risk Insurance Program Reauthorization Act of 2015 was enacted on January 12, 2015. The reauthorization provides for a federal government backstop for insured terrorism risks for another six years with increases to the insurer co-payment and program trigger. The existence of the mitigating effects of such law is part of the analysis of CNA’s overall risk posture for terrorism and, accordingly, its risk positioning may change if such law were modified. CNA also continues to invest in the security network of its systems on an enterprise-wide basis, especially considering the implications of data and privacy breaches. This requires an investment of a significant amount of resources by CNA on an ongoing basis. Potential implications of possible cybersecurity legislation on such current investment, if any, are uncertain. The foregoing proposals, either separately or in the aggregate, create a regulatory and legal environment that may require changes in CNA’s business plan or significant investment of resources in order to operate in an effective and compliant manner.

Additionally, various legislative and regulatory efforts to reform the tort liability system have, and will continue to, impact CNA’s industry. Although there has been some tort reform with positive impact to the insurance industry, new causes of action and theories of damages continue to be proposed in state court actions or by federal or state legislatures that continue to expand liability for insurers and their policyholders.

Properties: The Chicago location houses CNA’s principal executive offices. CNA’s subsidiaries lease office space in various cities throughout the United States and in other countries. The following table sets forth certain information with respect to CNA’s principal office locations:

DIAMOND OFFSHORE DRILLING, INC.

Diamond Offshore Drilling, Inc. (“Diamond Offshore”) is engaged, through its subsidiaries, in the business of operating drilling rigs that are chartered on a contract basis for fixed terms by companies engaged in the exploration and production of hydrocarbons. Offshore rigs are mobile units that can be relocated based on market demand. Diamond Offshore accounted for 18.1%, 19.7% and 20.0% of our consolidated total revenue for the years ended December 31, 2015, 2014 and 2013.

Rigs: Diamond Offshore provides contract drilling services to the energy industry around the world with a fleet of 32 offshore drilling rigs, which include four jack-up rigs that are being marketed for sale. Diamond Offshore’s fleet consists of 23 semisubmersibles including the Ocean GreatWhite, which is under construction, five jack-up rigs and four dynamically-positioned drillships including the last of Diamond Offshore’s four newbuild drillships, the Ocean BlackLion, which was delivered in the second quarter of 2015. Diamond Offshore expects its harsh environment ultra-deepwater semisubmersible rig, the Ocean GreatWhite, to be delivered in mid-2016.

A floater rig is a type of mobile offshore drilling unit that floats and does not rest on the seafloor. This asset class includes self-propelled drillships and semisubmersible rigs. Semisubmersible rigs consist of an upper working and living deck resting on vertical columns connected to lower hull members. Such rigs operate in a “semi-submerged” position, remaining afloat, off bottom, in a position in which the lower hull is approximately 55 feet to 90 feet below the water line and the upper deck protrudes well above the surface. Semisubmersibles hold position while drilling by use of a series of small propulsion units or thrusters that provide dynamic positioning (“DP”) to keep the rig on location, or with anchors tethered to the seabed. Although DP semisubmersibles are self-propelled, such rigs may be moved long distances with the assistance of tug boats. Non-DP, or moored, semisubmersibles require tug boats or the use of a heavy lift vessel to move between locations.

A drillship is an adaptation of a maritime vessel that is designed and constructed to carry out drilling operations by means of a substructure with a moon pool centrally located in the hull. Drillships are typically self-propelled and are positioned over a drillsite through the use of a DP system similar to those used on semisubmersible rigs.

Diamond Offshore’s floater fleet (semisubmersibles and drillships) can be further categorized based on the nominal water depth for each class of rig as follows:

Jack-up rigs are mobile, self-elevating drilling platforms equipped with legs that are lowered to the ocean floor. Diamond Offshore’s jack-ups are used for drilling in water depths from 20 feet to 350 feet. The water depth limit in which a particular rig is able to operate is principally determined by the length of the rig’s legs. The rig hull includes the drilling equipment, jacking system, crew quarters, loading and unloading facilities, storage areas for bulk and liquid materials, heliport and other related equipment. A jack-up rig is towed to the drillsite with its hull riding in the sea, as a vessel, with its legs retracted. Once over a drillsite, the legs are lowered until they rest on the seabed and jacking continues with the legs penetrating the seabed until they are firm and stable, and resistance is sufficient to elevate the hull above the surface of the water. After completion of drilling operations, the hull is lowered until it rests in the water and then the legs are retracted for relocation to another drillsite. All of Diamond Offshore’s jack-up rigs are equipped with a cantilever system that enables the rig to cantilever or extend its drilling package over the aft end of the rig.

Table of Contents

As of February 16, 2016, the Ocean Scepter, built in 2008, was operating offshore Mexico for Exploración Producción (“PEMEX”), under a long term contract. In addition, Diamond Offshore has four other jack-up rigs which it is currently marketing for sale.

Fleet Enhancements and Additions: Diamond Offshore’s long term strategy is to upgrade its fleet to meet customer demand for advanced, efficient and high-tech rigs by acquiring or building new rigs when possible to do so at attractive prices, and otherwise by enhancing the capabilities of its existing rigs at a lower cost and shortened construction period than newbuild construction would require. Since 2009, commencing with the acquisition of two newbuild, ultra-deepwater semisubmersible rigs, the Ocean Courage and Ocean Valor, Diamond Offshore has committed over $5.0 billion towards upgrading its fleet. In mid 2015, Diamond Offshore took delivery of the Ocean BlackLion, the last of four ultra-deepwater drillships constructed in South Korea during Diamond Offshore’s most recent fleet enhancement cycle. The Ocean GreatWhite remains under construction in South Korea with delivery of the new rig expected to occur in mid-2016. Upon completion of acceptance testing, the rig is expected to commence drilling operations offshore Australia later this year.

Diamond Offshore will evaluate further rig acquisition and enhancement opportunities as they arise. However, Diamond Offshore can provide no assurance whether, or to what extent, it will continue to make rig acquisitions or enhancements to its fleet.

Pressure Control by the Hour: In February of 2016, Diamond Offshore entered into a ten-year agreement with GE Oil & Gas, (“GE”), to provide services with respect to certain blowout preventer and related well control equipment on Diamond Offshore’s four newbuild drillships. Such services include management of maintenance, certification and reliability with respect to such equipment. In connection with the services agreement with GE, Diamond Offshore will sell the equipment to a GE affiliate and will lease back such equipment over separate ten-year operating leases.

Markets: The principal markets for Diamond Offshore’s contract drilling services are the following:

Diamond Offshore actively markets its rigs worldwide. From time to time Diamond Offshore’s fleet operates in various other markets throughout the world.

Drilling Contracts: Diamond Offshore’s contracts to provide offshore drilling services vary in their terms and provisions. Diamond Offshore typically obtains its contracts through a competitive bid process, although it is not unusual for Diamond Offshore to be awarded drilling contracts following direct negotiations. Drilling contracts generally provide for a basic fixed dayrate regardless of whether or not such drilling results in a productive well. Drilling contracts may also provide for reductions in rates during periods when the rig is being moved or when drilling operations are interrupted or restricted by equipment breakdowns, adverse weather conditions or other circumstances. Under dayrate contracts, Diamond Offshore generally pays the operating expenses of the rig, including wages and the cost of incidental supplies. Historically, dayrate contracts have accounted for the majority of Diamond Offshore’s revenues. In addition, from time to time, Diamond Offshore’s dayrate contracts may also provide for the ability to earn an incentive bonus from its customer based upon performance.

10

Table of Contents

The duration of a dayrate drilling contract is generally tied to the time required to drill a single well or a group of wells, which Diamond Offshore refers to as a well-to-well contract, or a fixed period of time, in what Diamond Offshore refers to as a term contract. Many drilling contracts may be terminated by the customer in the event the drilling rig is destroyed or lost or if drilling operations are suspended for an extended period of time as a result of a breakdown of equipment or, in some cases, due to events beyond the control of either party to the contract. Certain of Diamond Offshore’s contracts also permit the customer to terminate the contract early by giving notice; in most circumstances, this requires the payment of an early termination fee by the customer. The contract term in many instances may also be extended by the customer exercising options for the drilling of additional wells or for an additional length of time, generally at competitive market rates and mutually agreeable terms at the time of the extension. In periods of decreasing demand for offshore rigs, drilling contractors may prefer longer term contracts to preserve dayrates at existing levels and ensure utilization, while customers may prefer shorter contracts that allow them to more quickly obtain the benefit of declining dayrates. Moreover, drilling contractors may accept lower dayrates in a declining market in order to obtain longer-term contracts and add backlog.

Customers: Diamond Offshore provides offshore drilling services to a customer base that includes major and independent oil and gas companies and government-owned oil companies. During 2015, 2014 and 2013, Diamond Offshore performed services for 19, 35 and 39 different customers. During 2015, 2014 and 2013, one of Diamond Offshore’s customers in Brazil, Petróleo Brasileiro S.A. (“Petrobras”), (a Brazilian multinational energy company that is majority-owned by the Brazilian government), accounted for 24%, 32% and 34% of Diamond Offshore’s annual total consolidated revenues. During 2015, ExxonMobil and Anadarko each accounted for 12% of Diamond Offshore’s annual consolidated revenues. No other customer accounted for 10% or more of Diamond Offshore’s annual total consolidated revenues during 2015, 2014 or 2013.

As of February 16, 2016, Diamond Offshore’s contract backlog was $5.2 billion attributable to 11 customers. All four of its drillships are currently contracted to work in the GOM. As of February 16, 2016, contract backlog attributable to Diamond Offshore’s expected operations in the GOM was $510 million, $653 million and $653 million for the years 2016, 2017 and 2018, respectively, and $626 million in the aggregate for the years 2019 to 2020 attributable to three customers.

Competition: Despite consolidation in previous years, the offshore contract drilling industry remains highly competitive with numerous industry participants, none of which at the present time has a dominant market share. The industry may also experience additional consolidation in the future, which could create other large competitors. Some of Diamond Offshore’s competitors may have greater financial or other resources than it does. Based on industry data as of the date of this report, there are approximately 840 mobile drilling rigs in service worldwide, including approximately 300 floater rigs.

The offshore contract drilling industry is influenced by a number of factors, including global economies and demand for oil and natural gas, current and anticipated prices of oil and natural gas, expenditures by oil and gas companies for exploration and development of oil and natural gas and the availability of drilling rigs.

Drilling contracts are traditionally awarded on a competitive bid basis. Price is typically the primary factor in determining which qualified contractor is awarded a job. Customers may also consider rig availability and location, a drilling contractor’s operational and safety performance record, and condition and suitability of equipment. Diamond Offshore believes it competes favorably with respect to these factors.

Diamond Offshore competes on a worldwide basis, but competition may vary significantly by region at any particular time. Competition for offshore rigs generally takes place on a global basis, as these rigs are highly mobile and may be moved, at a cost that may be substantial, from one region to another. It is characteristic of the offshore contract drilling industry to move rigs from areas of low utilization and dayrates to areas of greater activity and relatively higher dayrates. Significant new rig construction and upgrades of existing drilling units could also intensify price competition.

Governmental Regulation: Diamond Offshore’s operations are subject to numerous international, foreign, U.S., state and local laws and regulations that relate directly or indirectly to its operations, including regulations controlling the discharge of materials into the environment, requiring removal and clean-up under some

11

Table of Contents

circumstances, or otherwise relating to the protection of the environment, and may include laws or regulations pertaining to climate change, carbon emissions or energy use.

Operations Outside the United States: Diamond Offshore’s operations outside the U.S. accounted for approximately 79%, 85% and 89% of its total consolidated revenues for the years ended December 31, 2015, 2014 and 2013.

Properties: Diamond Offshore owns an office building in Houston, Texas, where its corporate headquarters are located, offices and other facilities in New Iberia, Louisiana, Aberdeen, Scotland, Macae, Brazil and Ciudad del Carmen, Mexico. Additionally, Diamond Offshore currently leases various office, warehouse and storage facilities in Australia, Egypt, Indonesia, Louisiana, Malaysia, Romania, Singapore, Thailand, Trinidad and Tobago, the U.K. and Vietnam to support its offshore drilling operations.

Boardwalk Louisiana Midstream and Boardwalk Petrochemical Pipeline (collectively “Louisiana Midstream”) provide transportation and storage services for natural gas, NGL’s and ethylene, fractionation services for NGL’s and brine supply services. These assets provide approximately 67.1 MMBbls of salt dome storage capacity, including approximately 7.6 Bcf of working natural gas storage capacity and approximately 24.0 MMBbls of salt dome NGL storage capacity, significant brine supply infrastructure including three salt dome caverns and approximately 270 miles of pipeline assets.

Louisiana Midstream owns and operates the Evangeline Pipeline (“Evangeline”), which is an approximately 180 mile interstate ethylene pipeline that is capable of transporting approximately 2.6 billion pounds of ethylene per year between Texas and Louisiana, where it interconnects with Louisiana Midstream’s ethylene distribution system. Throughput for Louisiana Midstream was 46.6 MMBbls for the year ended December 31, 2015.

Boardwalk Field Services operates natural gas gathering, compression, treating and processing infrastructure primarily in south Texas with approximately 290 miles of pipeline.

In response to the change in the natural gas industry and the growth in the petrochemical industry, Boardwalk Pipeline is currently engaged in the following growth projects. See Liquidity and Capital Resources – Boardwalk Pipeline for further discussion of capital expenditures and financing.

Ohio to Louisiana Access Project: This project will provide long term firm natural gas transportation primarily from the Marcellus and Utica production areas to Louisiana, and while not creating additional capacity, would make a portion of Boardwalk Pipeline’s Texas Gas system bi-directional. The project is supported by firm transportation contracts with producers and end-users and has a weighted average contract life of approximately 13 years. The project is expected to be placed into service in the second quarter of 2016.

Southern Indiana Lateral Project: This project will consist of the construction of approximately 30 miles of pipeline from Indiana to Kentucky, adding approximately 0.1 Bcf per day of peak-day transmission capacity to Boardwalk Pipeline’s Texas Gas system. The project is expected to be placed into service in the third quarter of 2016, with a weighted-average contract life of 19 years.

Western Kentucky Market Lateral Project: This project consists of the construction of a pipeline lateral to provide deliveries to a proposed new power plant in Western Kentucky, adding approximately 0.2 Bcf per day of peak-day transmission capacity to Boardwalk Pipeline’s Texas Gas system. The project is expected to be placed into service in the third quarter of 2016, with a weighted-average contract life of 20 years.

Power Plant Project in South Texas: Boardwalk Pipeline’s power plant project consists of the addition of compression facilities and modifications of existing facilities to increase the operating capacity of certain sections of the Gulf South pipeline, providing transportation services of 0.2 Bcf per day to a new power plant in South Texas. The project is expected to be placed into service in the third quarter of 2016, with a weighted-average contract life of 20 years.

Northern Supply Access Project: This project will increase the peak-day transmission capacity on Boardwalk Pipeline’s Texas Gas system by the addition of compression facilities and other system modifications to make this portion of the system bi-directional and is supported by precedent agreements for 0.4 Bcf per day of peak-day transmission capacity. The project is expected to be placed into service in the first half of 2017, with a weighted-average contract life of 16 years. In October of 2015, one of the foundation shippers which contracted for 0.1 Bcf per day of peak-day transmission capacity failed to post the required credit support on the contractually required date. Boardwalk Pipeline continues to work with the customer as well as explore all options for the capacity associated with that customer’s precedent agreement, including adjusting the scope of the project to accommodate the reduced volume commitment. This project remains subject to the Federal Energy Regulatory Commission (“FERC”) regulatory approval to commence construction.

Sulphur Storage and Pipeline Expansion Project: Boardwalk Pipeline executed a long term agreement to provide liquids transportation and storage services to support the development of a new ethane cracker plant in Louisiana. The project will involve significant storage and infrastructure development to serve petrochemical customers near Boardwalk Pipeline’s Sulphur Hub and is expected to be placed into service in the second half of 2017.

Coastal Bend Header Project: Boardwalk Pipeline executed precedent agreements with foundation shippers to transport natural gas to serve a planned liquefied natural gas (“LNG”) liquefaction terminal in Freeport, Texas. As part of the project Boardwalk Pipeline will construct an approximately 65-mile pipeline supply header with approximate 1.4 Bcf per day of capacity to serve the terminal. Additionally, Boardwalk Pipeline will expand and modify its existing Gulf South pipeline facilities that will provide access to additional supply sources through various interconnects in South Texas and in the Louisiana area. The project is expected to be placed into service in 2018, with a weighted-average contract life of 20 years. This project remains subject to FERC regulatory approval to commence construction.

Brine Development Project: Boardwalk Pipeline executed agreements with a petrochemical customer in Louisiana to provide brine supply services subject to certain minimum take requirements. The first portion of the project, which was placed into service in the fourth quarter of 2015, consisted of constructing a pipeline to the customer’s facilities to supply brine over a three year period. The second portion, expected to be placed in service in 2018, consists of providing brine supply services over a 15-year period through the development of additional wells and associated facilities.

Customers: Boardwalk Pipeline serves a broad mix of customers, including producers of natural gas, and with end-use customers including local distribution companies, marketers, electric power generators, industrial users and interstate and intrastate pipelines who, in turn, provide transportation and storage services for end-users. These customers are located throughout the Gulf Coast, Midwest and Northeast regions of the U.S.

Competition: Boardwalk Pipeline competes with numerous other pipelines that provide transportation, storage and other services at many locations along its pipeline systems. Boardwalk Pipeline also competes with pipelines that are attached to natural gas supply sources that are closer to some of its traditional natural gas market areas. In addition, regulators’ continuing efforts to increase competition in the natural gas industry have increased the natural gas transportation options of Boardwalk Pipeline’s traditional customers. For example, as a result of regulators’ policies, capacity segmentation and capacity release have created an active secondary market which increasingly competes with Boardwalk Pipeline’s natural gas pipeline services. Further, natural gas competes with other forms of energy available to Boardwalk Pipeline’s customers, including electricity, coal, fuel oils and alternative fuel sources.

The principal elements of competition among pipelines are availability of capacity, rates, terms of service, access to gas supplies, flexibility and reliability of service. In many cases, the elements of competition, in particular flexibility, terms of service and reliability, are key differentiating factors between competitors. This is especially the case with capacity being sold on a longer term basis. Boardwalk Pipeline is focused on finding opportunities to enhance its competitive profile in these areas by increasing the flexibility of its pipeline systems, such as modifying them to allow for bi-directional flows, to meet the demands of customers, such as power generators and industrial users, and is continually reviewing its services and terms of service to offer customers enhanced service options.

Seasonality: Boardwalk Pipeline’s revenues can be affected by weather, natural gas price levels, gas price differentials between locations on its pipeline systems (basis spreads), gas price differentials between time periods, such as winter to summer (time period price spreads) and natural gas price volatility. Weather impacts natural gas demand for heating needs and power generation, which in turn influences the short term value of transportation and storage across Boardwalk Pipeline’s pipeline systems. Colder than normal winters can result in an increase in the demand for natural gas for heating needs and warmer than normal summers can impact cooling needs, both of which typically result in increased pipeline transportation revenues and throughput. While traditionally peak demand for natural gas occurs during the winter months driven by heating needs, the increased use of natural gas for cooling needs during the summer months has partially reduced the seasonality of revenues. In 2015, approximately 53% of Boardwalk Pipeline’s operating revenues were recognized in the first and fourth quarters of the year.

Governmental Regulation: FERC regulates Boardwalk Pipeline’s natural gas operating subsidiaries under the Natural Gas Act of 1938 (“NGA”) and the Natural Gas Policy Act of 1978. FERC regulates, among other things, the rates and charges for the transportation and storage of natural gas in interstate commerce and the extension, enlargement or abandonment of facilities under its jurisdiction. Where required, Boardwalk Pipeline’s natural gas pipeline subsidiaries hold certificates of public convenience and necessity issued by FERC covering certain of their facilities, activities and services. The maximum rates that may be charged by Boardwalk Pipeline’s subsidiaries operating under FERC’s jurisdiction, for all aspects of the natural gas transportation services it provides, are established through FERC’s cost-of-service rate-making process. Key determinants in FERC’s cost-of-service rate-making process are the costs of providing service, the volumes of gas being transported, the rate design, the allocation of costs between services, the capital structure and the rate of return a pipeline is permitted to earn. The maximum rates that may be charged by Boardwalk Pipeline for storage services on Texas Gas, with the exception of services associated with a portion of the working gas capacity on that system, are established through FERC’s cost-of-service rate-making process. FERC has authorized Boardwalk Pipeline to charge market-based rates for its firm and interruptible storage services for the majority of its natural gas storage facilities.

In October of 2014, Boardwalk Pipeline’s Gulf South subsidiary filed a rate case with the FERC pursuant to Section 4 of the Natural Gas Act of 1938 (Docket No. RP15-65) in which Gulf South requested, among other things, a reconfiguration of the transportation rate zones on its system and, in general, an increase in its tariff rates. In 2015, an uncontested settlement was reached with Gulf South’s customers and approved by the FERC. The settlement will become effective March 1, 2016.

The settlement provides for, among other things, (a) a system-wide rate design across the majority of the pipeline system; (b) a fuel tracker for determining future fuel rates; (c) a moratorium which prevents Gulf South or its customers from modifying the settlement rates until May 1, 2023, with certain exceptions; and (d) an extension of all No Notice Service (“NNS”) contracts to the end of the moratorium period at maximum rates, subject to each customer’s right to reduce capacity under those agreements from current levels by up to 6% on April 1, 2016 and by up to another 6% of their remaining contract capacity by April 1, 2020. The NNS customers had to elect by December 1, 2015, whether they wanted to reduce their initial contracted capacity. Only two NNS customers elected to reduce their contracted capacity effective on April 1, 2016. The settled rates were moved into effect on November 1, 2015. Refunds for the difference between the rates as filed and as settled are required to be paid to customers by May 1, 2016. Please see “Gulf South Rate Case” under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”).

Boardwalk Pipeline is also regulated by the U.S. Department of Transportation (“DOT”) through the Pipeline and Hazardous Material Safety Administration (“PHMSA”) under the Natural Gas Pipeline Safety Act of 1968, as amended by Title I of the Pipeline Safety Act of 1979 (“NGPSA”) and the Hazardous Liquids Pipeline Safety Act of 1979 (“HLPSA”). The NGPSA and HLPSA govern the design, installation, testing, construction, operation, replacement and management of interstate natural gas and NGL pipeline facilities. Boardwalk Pipeline has received authority from PHMSA to operate certain natural gas pipeline assets under special permits that will allow it to operate those pipeline assets at higher than normal operating pressures of up to 0.80 of the pipe’s Specified Minimum Yield Strength (“SMYS”). Operating at higher than normal operating pressures will allow these pipelines to transport all of the volumes Boardwalk Pipeline has contracted for with its customers. PHMSA retains discretion whether to grant or maintain authority for Boardwalk Pipeline to operate its natural gas pipeline assets at higher pressures. PHMSA has also developed regulations that require transportation pipeline operators to implement integrity management programs to comprehensively evaluate certain high risk areas along Boardwalk Pipeline’s pipelines and take additional measures to protect pipeline segments located in highly populated areas. The NGPSA and HLPSA were most recently amended by the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (“2011 Act”) in 2012, with the 2011 Act requiring increased maximum civil penalties for certain violations to $200,000 per violation per day, and a total cap of $2 million. In addition, the 2011 Act reauthorized the federal pipeline safety programs of PHMSA through 2015, and directs the Secretary of Transportation to undertake a number of reviews, studies and reports, some of which may result in more stringent safety controls or additional natural gas and hazardous liquids pipeline safety rulemaking. A number of the provisions of the 2011 Act have the potential to cause owners and operators of pipeline facilities to incur significant capital expenditures and/or operating costs. New pipeline safety legislation that will reauthorize the federal pipeline safety programs of PHMSA through 2019 will be under consideration. Passage of new legislation reauthorizing the PHMSA pipeline safety

programs is expected to require, among other things, pursuit of those legal mandates included in the 2011 Act but not acted upon by PHMSA.

The Surface Transportation Board (“STB”), has authority to regulate the rates Boardwalk Pipeline charges for service on its ethylene pipelines. The STB requires that Boardwalk Pipeline’s transportation rates be reasonable and that its practices cannot unreasonably discriminate among its ethylene shippers.

Boardwalk Pipeline’s operations are also subject to extensive federal, state, and local laws and regulations relating to protection of the environment. Such laws and regulations impose, among other things, restrictions, liabilities and obligations in connection with the generation, handling, use, storage, transportation, treatment and disposal of hazardous substances and waste and in connection with spills, releases, discharges and emissions of various substances into the environment. Environmental regulations also require that Boardwalk Pipeline’s facilities, sites and other properties be operated, maintained, abandoned and reclaimed to the satisfaction of applicable regulatory authorities.

Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of corrective or remedial obligations, the occurrence of delays in the development of projects and the issuance of orders enjoining performance of some or all of Boardwalk Pipeline’s operations in the affected areas. While Boardwalk Pipeline believes that its past operations have not resulted in the incurrence of material costs with respect to these existing environmental laws and regulations, it can provide no assurance that continued compliance with existing requirements will not materially affect them, or that the current regulatory standards will not become more onerous in the future, resulting in more significant costs to maintain compliance or increased exposure to significant liabilities.

Properties: Boardwalk Pipeline is headquartered in approximately 103,000 square feet of leased office space located in Houston, Texas. Boardwalk Pipeline also leases approximately 60,000 square feet of office space in Owensboro, Kentucky. Boardwalk Pipeline’s operating subsidiaries own their respective pipeline systems in fee. However, substantial portions of these systems are constructed and maintained on property owned by others pursuant to rights-of-way, easements, permits, licenses or consents.

LOEWS HOTELS HOLDING CORPORATION

The subsidiaries of Loews Hotels Holding Corporation (collectively “Loews Hotels”), our wholly owned subsidiary, presently operate a chain of 24 primarily upper, upscale hotels. Thirteen of these hotels are owned by Loews Hotels, nine are owned by joint ventures in which Loews Hotels has equity interests and two are managed for unaffiliated owners. Loews Hotels’ earnings are derived from the operation of its wholly owned hotels, its share of earnings in joint venture hotels and hotel management fees earned from both joint venture and managed hotels. Loews Hotels accounted for 4.5%, 3.3% and 2.6% of our consolidated total revenue for the years ended December 31, 2015, 2014 and 2013. The hotels are described below.

Competition: Competition from other hotels and lodging facilities is vigorous in all areas in which Loews Hotels operates. The demand for hotel rooms is seasonal and dependent on general and local economic conditions. Loews Hotels properties also compete with facilities offering similar services in locations other than those in which its hotels are located. Competition among luxury hotels is based primarily on quality of location, facilities and service. Competition among resort and commercial hotels is based on price and facilities as well as location and service. Because of the competitive nature of the industry, hotels must continually make expenditures for updating, refurnishing and repairs and maintenance, in order to prevent competitive obsolescence.

Risks Related to Us and Our Subsidiary, CNA Financial Corporation

If CNA determines that its recorded insurance reserves are insufficient to cover its estimated ultimate unpaid liability for claim and claim adjustment expenses, CNA may need to increase its insurance reserves which would result in a charge to CNA’s earnings.

CNA maintains insurance reserves to cover its estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for reported and unreported claims. Insurance reserves are not an exact calculation of liability but instead are complex management estimates developed utilizing a variety of actuarial reserve estimation techniques as of a given reporting date. The reserve estimation process involves a high degree of judgment and variability and is subject to a number of variables which are highly uncertain. These variables can be affected by both changes in internal processes and external events. Key variables include claims severity, frequency of claims, mortality, morbidity, discount rates, inflation, claims handling, policies and procedures, case reserving approach, underwriting and pricing policies, changes in the legal and regulatory environment and the lag time between the occurrence of an insured event and the time of its ultimate settlement. Mortality is the relative incidence of death. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted.

There is generally a higher degree of variability in estimating required reserves for long-tail coverages, such as general liability and workers’ compensation, as they require a relatively longer period of time for claims to be reported and settled. The impact of changes in inflation and medical costs are more pronounced for long-tail coverages due to the longer settlement period.

CNA is also subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on CNA’s business by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims, resulting in further increases in CNA’s reserves. The effects of these and other unforeseen emerging claim and coverage issues are extremely difficult to predict.

Emerging or potential claims and coverage issues include, but are not limited to, uncertainty in future medical costs in workers’ compensation. In particular, medical cost inflation could be greater than expected due to new treatments, drugs and devices; increased health care utilization; and/or the future costs of health care facilities. In addition, the relationship between workers’ compensation and government and private health care providers could change, potentially shifting costs to workers’ compensation.

In light of the many uncertainties associated with establishing the estimates and making the judgments necessary to establish reserve levels, CNA continually reviews and changes its reserve estimates in a regular and ongoing process as experience develops from the actual reporting and settlement of claims and as the legal, regulatory and economic environment evolves. If CNA’s recorded reserves are insufficient for any reason, the required increase in reserves would be recorded as a charge against earnings in the period in which reserves are determined to be insufficient. These charges could be substantial.

CNA’s actual experience could vary from the key assumptions used to determine active life reserves for long term care policies.

CNA’s active life reserves for long term care policies are based on CNA’s best estimate assumptions as of December 31, 2015 with no margin for adverse deviation. Key assumptions include morbidity, persistency (the percentage of policies remaining in force), discount rate and future premium rate increases. These assumptions, which are critical bases for its reserve estimates are inherently uncertain. If actual experience varies from these assumptions or the future outlook for these assumptions changes, CNA may be required to increase its reserves. See the Life & Group Non-Core Policyholder Reserves portion of Reserves – Estimates and Uncertainties section of MD&A in Item 7 for more information.

20

Table of Contents

Estimating future experience for long term care policies is highly uncertain because the required projection period is very long and there is limited historical data and industry data available to CNA, as only a small portion of the long term care policies which have been written to date are in claims paying status. Morbidity and persistency trends can be volatile and may be negatively affected by many factors including, but not limited to policyholder behavior, socioeconomic factors, changes in health trends and advances in medical care.

A prolonged period during which interest rates remain at levels lower than those anticipated in CNA’s reserving would result in shortfalls in investment income on assets supporting CNA’s obligations under long term care policies, which may require changes to its reserves. This risk is more significant for CNA’s long term care products because the long potential duration of the policy obligations exceeds the duration of the supporting investment assets. In addition, CNA may not receive regulatory approval for the level of premium rate increases it requests. Any adverse deviation between the level of future premium rate increases approved and the level included in CNA’s reserving assumptions may require an increase to its reserves.

If CNA’s estimated reserves are insufficient for any reason, including changes in assumptions, the required increase in reserves would be recorded as a charge against earnings in the period in which reserves are determined to be insufficient. These charges could be substantial.

Catastrophe losses are unpredictable and could result in material losses.

Catastrophe losses are an inevitable part of CNA’s business. Various events can cause catastrophe losses. These events can be natural or man-made, and may include hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil commotion and acts of terrorism. The frequency and severity of these catastrophe events are inherently unpredictable. In addition, longer-term natural catastrophe trends may be changing and new types of catastrophe losses may be developing due to climate change, a phenomenon that has been associated with extreme weather events linked to rising temperatures, and includes effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow.

The extent of CNA’s losses from catastrophes is a function of the total amount of its insured exposures in the affected areas, the frequency and severity of the events themselves, the level of reinsurance assumed and ceded reinsurance reinstatement premiums and state residual market assessments, if any. As in the case of catastrophe losses generally, it can take a long time for the ultimate cost to CNA to be finally determined, as a multitude of factors contribute to such costs, including evaluation of general liability and pollution exposures, additional living expenses, infrastructure disruption, business interruption and reinsurance collectibility. Reinsurance coverage for terrorism events is provided only in limited circumstances, especially in regard to “unconventional” terrorism acts, such as nuclear, biological, chemical or radiological attacks. As a result of the items discussed above, catastrophe losses are particularly difficult to estimate.

Additionally, claim frequency and severity for some lines of business can be correlated to an external factor such as economic activity, financial market volatility, increasing health care costs or changes in the legal or regulatory environment. Claim frequency and severity can also be correlated to insureds’ use of common business practices, equipment, vendors or software. This can result in multiple insured losses emanating out of the same underlying cause. In these instances, CNA may be subject to increased claim frequency and severity across multiple policies or lines of business concurrently. While CNA does not define such instances as catastrophes for financial reporting purposes, they are similar to catastrophes in terms of the uncertainty and potential impact on its results.

CNA has exposure related to A&EP claims, which could result in material losses.

CNA’s property and casualty insurance subsidiaries have exposures related to A&EP claims. CNA’s experience has been that establishing claim and claim adjustment expense reserves for casualty coverages relating to A&EP claims is subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment expense reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability.

21

Table of Contents

On August 31, 2010, CNA completed a retroactive reinsurance transaction under which substantially all of its legacy A&EP liabilities were ceded to National Indemnity Company (“NICO”), a subsidiary of Berkshire Hathaway Inc., subject to an aggregate limit of $4.0 billion (loss portfolio transfer or “LPT”). The cumulative amount ceded under the loss portfolio transfer as of December 31, 2015 is $2.6 billion. If the other parties to the loss portfolio transfer do not fully perform their obligations, net losses incurred on A&EP claims covered by the loss portfolio transfer exceed the aggregate limit of $4.0 billion or CNA determines it has exposures to A&EP claims not covered by the loss portfolio transfer, CNA may need to increase its recorded net reserves which would result in a charge against earnings. These charges could be substantial.

CNA faces intense competition in its industry; CNA may be adversely affected by the cyclical nature of the property and casualty business as well as the availability and cost of reinsurance.

All aspects of the insurance industry are highly competitive and CNA must continuously allocate resources to refine and improve its insurance products and services. CNA competes with a large number of stock and mutual insurance companies and other entities for both distributors and customers. Insurers compete on the basis of factors including products, price, services, ratings and financial strength. The competitor insurer landscape has evolved substantially in recent years, with significant consolidation and new market entrants, resulting in increased pressures on CNA’s ability to remain competitive, particularly in implementing pricing that is both attractive to CNA’s customer base and risk appropriate to CNA. In addition, the property and casualty market is cyclical and has experienced periods characterized by relatively high levels of price competition, resulting in less restrictive underwriting standards and relatively low premium rates, followed by periods of relatively lower levels of competition, more selective underwriting standards and relatively high premium rates. During periods in which price competition is high, CNA may lose business to competitors offering competitive insurance products at lower prices. As a result, CNA’s premium levels and expense ratio could be materially adversely impacted.

Additionally, CNA purchases reinsurance to help manage its exposure to risk. Under CNA’s ceded reinsurance arrangements, another insurer assumes a specified portion of CNA’s exposure in exchange for a specified portion of policy premiums. Market conditions determine the availability and cost of the reinsurance protection CNA purchases, which affects the level of its business and profitability, as well as the level and types of risk CNA retains. If CNA is unable to obtain sufficient reinsurance at a cost it deems acceptable, CNA may be unwilling to bear the increased risk and would reduce the level of its underwriting commitments.

CNA may not be able to collect amounts owed to it by reinsurers, which could result in higher net incurred losses.

CNA has significant amounts recoverable from reinsurers which are reported as receivables on its balance sheets and are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. The ceding of insurance does not, however, discharge CNA’s primary liability for claims. As a result, CNA is subject to credit risk relating to its ability to recover amounts due from reinsurers. Certain of CNA’s reinsurance carriers have experienced credit downgrades by rating agencies within the term of CNA’s contractual relationship which increases the likelihood that CNA will not be able to recover amounts due. In addition, reinsurers could dispute amounts which CNA believes are due to it. If the amounts CNA collects from reinsurers are less than the amount recorded for any of the foregoing reasons, its net incurred losses will be higher.

CNA may not be able to collect amounts owed to it by policyholders who hold deductible policies and/or who purchase retrospectively rated policies, which could result in higher net incurred losses.

A portion of CNA’s business is written under deductible policies. Under these policies, CNA is obligated to pay the related insurance claims and are reimbursed by the policyholder to the extent of the deductible, which may be significant. As a result, CNA is exposed to credit risk to the policyholder. If the amounts CNA collects from policyholders are less than the amounts recorded, its incurred losses will be higher.

Moreover, certain policyholders purchase retrospectively rated workers’ compensation policies (i.e., policies in which premiums are adjusted after the policy period based on the actual loss experience of the policyholder during the policy period). Retrospectively rated policies expose CNA to additional credit risk to the extent that the adjusted premium is greater than the original premium.

CNA may incur significant realized and unrealized investment losses and volatility in net investment income arising from changes in the financial markets.

CNA’s investment portfolio is exposed to various risks, such as interest rate, credit spread, issuer default, equity prices and foreign currency, which are unpredictable. Financial markets are highly sensitive to changes in economic conditions, monetary policies, domestic and international geopolitical issues and many other factors. Changes in financial markets including fluctuations in interest rates, credit, equity prices and foreign currency prices, and many other factors beyond CNA’s control can adversely affect the value of its investments, the realization of investment income and the rate at which it discounts certain liabilities.

CNA has significant holdings in fixed maturity investments that are sensitive to changes in interest rates. A decline in interest rates may reduce the returns earned on new fixed maturity investments, thereby reducing CNA’s net investment income, while an increase in interest rates may reduce the value of its existing fixed maturity investments. The value of CNA’s fixed maturity investments is also subject to risk that certain investments may default or become impaired due to deterioration in the financial condition of issuers of the investments CNA holds. Any such impairments which CNA deems to be other-than-temporary would result in a charge to earnings.

In addition, CNA invests a portion of its assets in equity securities and limited partnerships which are subject to greater market volatility than its fixed maturity investments. Limited partnership investments generally provide a lower level of liquidity than fixed maturity or equity investments and therefore may also limit CNA’s ability to withdraw assets. As a result of all of these factors, CNA may not earn an adequate return on its investments, may be required to write down the value of its investments and may incur losses on the disposition of its investments.

CNA is subject to capital adequacy requirements and, if it is unable to maintain or raise sufficient capital to meet these requirements, regulatory agencies may restrict or prohibit CNA from operating its business.

Insurance companies such as CNA are subject to capital adequacy standards set by regulators to help identify companies that merit further regulatory attention. These standards apply specified risk factors to various asset, premium and reserve components of CNA’s legal entity statutory basis of accounting financial statements. Current rules, including those promulgated by insurance regulators and specialized markets such as Lloyd’s, require companies to maintain statutory capital and surplus at a specified minimum level determined using the applicable jurisdiction’s regulatory capital adequacy formula. If CNA does not meet these minimum requirements, CNA may be restricted or prohibited from operating its business. If CNA is required to record a material charge against earnings in connection with a change in estimate or the occurrence of an event or if it incurs significant losses related to its investment portfolio, CNA may violate these minimum capital adequacy requirements unless it is able to raise sufficient additional capital. CNA may be limited in its ability to raise significant amounts of capital on favorable terms or at all.

Globally, insurance regulators are working cooperatively to develop a common framework for the supervision of internationally active insurance groups. Finalization and adoption of this framework could increase CNA’s minimum regulatory capital requirement as well as significantly increase its cost of regulatory compliance.

CNA’s insurance subsidiaries, upon whom CNA depends for dividends in order to fund its working capital needs, are limited by insurance regulators in their ability to pay dividends.

CNA is a holding company and is dependent upon dividends, loans and other sources of cash from its subsidiaries in order to meet its obligations. Ordinary dividend payments or dividends that do not require prior approval by the insurance subsidiaries’ domiciliary insurance regulator are generally limited to amounts determined by formula which varies by jurisdiction. If CNA is restricted, by regulatory rule or otherwise, from paying or receiving intercompany dividends, CNA may not be able to fund its working capital needs and debt service requirements from available cash. As a result, CNA would need to look to other sources of capital which may be more expensive or may not be available at all.

Rating agencies may downgrade their ratings of CNA and thereby adversely affect its ability to write insurance at competitive rates or at all.

Ratings are an important factor in establishing the competitive position of insurance companies. CNA’s insurance company subsidiaries, as well as CNA’s public debt, are rated by rating agencies, namely, A.M. Best Company (“A.M. Best”), Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s (“S&P”). Ratings reflect the rating agency’s opinions of an insurance company’s or insurance holding company’s financial strength, capital adequacy, operating performance, strategic position and ability to meet its obligations to policyholders and debt holders.

The rating agencies may take action to lower CNA’s ratings in the future as a result of any significant financial loss or possible changes in the methodology or criteria applied by the rating agencies. The severity of the impact on CNA’s business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of CNA’s insurance products to certain markets and the required collateralization of certain future payment obligations or reserves.

In addition, it is possible that a lowering of our corporate debt ratings by certain of the rating agencies could result in an adverse impact on CNA’s ratings, independent of any change in CNA’s circumstances.

Risks Related to Us and Our Subsidiary, Diamond Offshore Drilling, Inc.

The worldwide demand for Diamond Offshore’s drilling services has declined significantly as a result of the decline in oil prices, which commenced during the second half of 2014 and has continued into 2016.

Demand for Diamond Offshore’s drilling services depends in large part upon oil and natural gas industry offshore exploration and production activity and expenditure levels, which are directly affected by oil and gas prices and market expectations of potential changes in oil and gas prices. Commencing in the second half of 2014, oil prices have declined precipitously and recently fell to a 12-year low of less than $30 per barrel. The dramatic reduction in commodity prices has caused a sharp decline in the demand for offshore drilling services, including services that Diamond Offshore provides and adversely affected its operations and cash flows in 2015. A prolonged period of low oil prices would have a material adverse effect on many of Diamond Offshore’s customers and, therefore its business.

Oil prices have been, and are expected to continue to be, volatile and are affected by numerous factors beyond Diamond Offshore’s control, including:

24

Table of Contents

An increase in commodity demand and prices will not necessarily result in an immediate increase in offshore drilling activity since Diamond Offshore’s customers’ project development times, reserve replacement needs, and expectations of future commodity demand, prices and supply of available competing rigs all combine to affect demand for its rigs.

Diamond Offshore’s business depends on the level of activity in the offshore oil and gas industry, which has been cyclical and is significantly affected by many factors outside of its control.

Demand for Diamond Offshore’s drilling services depends upon the level of offshore oil and gas exploration, development and production in markets worldwide, and those activities depend in large part on oil and gas prices, worldwide demand for oil and gas and a variety of political and economic factors. The level of offshore drilling activity is also adversely affected when operators reduce or defer new investment in offshore projects, reduce or suspend their drilling budgets or reallocate their drilling budgets away from offshore drilling in favor of other priorities, such as shale or other land-based projects, which could reduce demand for Diamond Offshore’s rigs and newbuilds. As a result, Diamond Offshore’s business and the oil and gas industry in general are subject to cyclical fluctuations.

As a result of the cyclical fluctuations in the market, there have been periods of lower demand, excess rig supply and lower dayrates, followed by periods of higher demand, shorter rig supply and higher dayrates. Diamond Offshore cannot predict the timing or duration of such fluctuations. Periods of lower demand or excess rig supply intensify the competition in the industry and often result in periods of lower utilization and lower dayrates. During these periods, Diamond Offshore’s rigs may not obtain contracts for future work and may be idle for long periods of time or may be able to obtain work only under contracts with lower dayrates or less favorable terms which could have a material adverse effect on Diamond Offshore’s business during these periods. Additionally, prolonged periods of low utilization and dayrates could also result in the recognition of impairment charges on certain of Diamond Offshore’s drilling rigs if future cash flow estimates, based upon information available to management at the time, indicate that the carrying value of these rigs may not be recoverable.

Diamond Offshore’s industry is highly competitive, with oversupply and intense price competition.

The offshore contract drilling industry is highly competitive with numerous industry participants. Some of Diamond Offshore’s competitors may be larger companies, have larger or more technologically advanced fleets and have greater financial or other resources than it does. The drilling industry has experienced consolidation in the past

25

Table of Contents

and may experience additional consolidation, which could create additional large competitors. Drilling contracts are traditionally awarded on a competitive bid basis. Price is typically the primary factor in determining which qualified contractor is awarded a job; however, rig availability and location, a drilling contractor’s safety record and the quality and technical capability of service and equipment may also be considered.

Recent new rig construction and upgrades of existing drilling rigs, cancelation or termination of contracts, as well as established rigs coming off contract during 2015, have contributed to the current oversupply of drilling rigs intensifying price competition. Additional newbuild rigs entering the market are expected to further negatively impact rig utilization and intensify price competition as rigs are delivered.

Diamond Offshore provides offshore drilling services to a customer base that includes major and independent oil and gas companies and government-owned oil companies. During 2015, one of Diamond Offshore’s customers in Brazil, Petrobras, and Diamond Offshore’s five largest customers in the aggregate accounted for 24% and 65%, of its annual total consolidated revenues. The loss of a significant customer could have a material adverse impact on Diamond Offshore’s financial results especially in a declining market where the number of Diamond Offshore’s working drilling rigs is declining along with the number of its active customers. In addition, if a significant customer experiences liquidity constraints or other financial difficulties, it could materially adversely affect utilization rates in the affected market and also displace demand for Diamond Offshore’s other drilling rigs and newbuilds as the resulting excess supply enters the market. While it is normal for Diamond Offshore’s customer base to change over time as work programs are completed, the loss of or a significant reduction in the number of rigs contracted with any major customer may have a material adverse effect on Diamond Offshore’s future business.

Diamond Offshore can provide no assurance that its drilling contracts will not be terminated early or that its current backlog of contract drilling revenue will be ultimately realized.

Currently, Diamond Offshore’s customers may terminate their drilling contracts under certain circumstances, such as if the drilling rig is destroyed or lost, if Diamond Offshore suspends drilling operations for a specified period of time as a result of a breakdown of major equipment, excessive downtime for repairs, failure to meet minimum performance criteria (including customer acceptance testing) or, in some cases, due to other events beyond the control of either party. Diamond Offshore’s drilling contract for the Ocean BlackLion, for example, requires it to successfully complete certain testing procedures for the rig’s equipment, including the blowout preventers and well control systems. Diamond Offshore is currently undergoing the required testing. If these tests are not successfully completed, Diamond Offshore’s customer has the right to terminate the drilling contract or may request a renegotiation of the terms of the contract.

In addition, some of Diamond Offshore’s drilling contracts permit the customer to terminate the contract after specified notice periods often by tendering contractually specified termination amounts, which may not fully compensate Diamond Offshore for the loss of the contract. During depressed market conditions, certain customers have utilized such contract clauses to seek to renegotiate or terminate a drilling contract or claim that Diamond Offshore has breached provisions of its drilling contracts in order to avoid their obligations to Diamond Offshore under circumstances where it believes it is in compliance with the contracts. Additionally, because of depressed commodity prices, restricted credit markets, economic downturns, changes in priorities or strategy or other factors beyond Diamond Offshore’s control, a customer may no longer want or need a rig that is currently under contract or may be able to obtain a comparable rig at a lower dayrate. For these reasons, customers may seek to renegotiate the terms of Diamond Offshore’s existing drilling contracts, terminate their contracts without justification or repudiate or otherwise fail to perform their obligations under the contracts. Such renegotiations could include requests to lower the contract dayrate, lowering of a dayrate in exchange for additional contract term, shortening the term on one contracted rig in exchange for additional term on another rig, early termination of a contract in exchange for a lump sum margin payout and many other possibilities. Diamond Offshore’s contract backlog may be adversely impacted as a result of such contract renegotiations.

When a customer terminates a contract prior to the contract’s scheduled expiration, Diamond Offshore’s contract backlog is adversely impacted, and it might not recover any compensation for the termination or any recovery Diamond Offshore might obtain may not fully compensate it for the loss of the contract. In any case, the early termination of a contract may result in Diamond Offshore’s rig being idle for an extended period of time. Each of these results could have a material adverse effect on Diamond Offshore’s business. In addition, if a customer cancels

26

Table of Contents

a contract or if Diamond Offshore elects to terminate a contract due to the customer’s nonperformance and in either case Diamond Offshore is unable to secure a new contract on a timely basis and on substantially similar terms, or if a contract is disputed or suspended for an extended period of time or if a contract is renegotiated, it could materially and adversely affect Diamond Offshore’s business.

Generally, Diamond Offshore’s contract backlog only includes future revenues under firm commitments; however, from time to time, Diamond Offshore may report anticipated commitments for which definitive agreements have not yet been, but are expected to be, executed. Diamond Offshore can provide no assurance in such cases that it will be able to ultimately execute a definitive agreement. In addition, for the reasons described above, Diamond Offshore can provide no assurance that its customers will be willing or able to fulfill their contractual commitments. Diamond Offshore’s inability to perform under its contractual obligations or to execute definitive agreements, or its customers’ inability or unwillingness to fulfill their contractual commitments to Diamond Offshore, may have a material adverse effect on Diamond Offshore’s business.

Diamond Offshore may not be able to renew or replace expiring contracts for its rigs.

Diamond Offshore has a number of customer contracts that will expire in 2016 and 2017. Diamond Offshore’s ability to renew or replace expiring contracts or obtain new contracts, and the terms of any such contracts, will depend on various factors, including market conditions and the specific needs of its customers. Given the highly competitive and historically cyclical nature of the industry, Diamond Offshore may not be able to renew or replace the contracts or it may be required to renew or replace expiring contracts or obtain new contracts at dayrates that are below, and potentially substantially below, existing dayrates, or that have terms that are less favorable than existing contracts or it may be unable to secure contracts for these rigs.

Diamond Offshore’s contract drilling expense includes fixed costs that will not decline in proportion to decreases in rig utilization and dayrates.

Diamond Offshore’s contract drilling expense includes all direct and indirect costs associated with the operation, maintenance and support of its drilling equipment, which is often not affected by changes in dayrates and utilization. During periods of reduced revenue and/or activity, certain of Diamond Offshore’s fixed costs will not decline and often it may incur additional operating costs, such as fuel and catering costs, for which it is generally reimbursed by the customer when a rig is under contract. During times of reduced utilization, reductions in costs may not be immediate as Diamond Offshore may incur additional costs associated with cold stacking of a rig (particularly if Diamond Offshore cold stacks a newer rig, such as a drillship, for which cold stacking costs are typically substantially higher than for a jack-up rig or an older floater rig), or it may not be able to fully reduce the cost of its support operations in a particular geographic region due to the need to support the remaining drilling rigs in that region. A decline in revenue due to lower dayrates and/or utilization may not be offset by a corresponding decrease in contract drilling expense and could have a material adverse effect on Diamond Offshore’s business.

Diamond Offshore may enter into drilling contracts that expose it to greater risks than it normally assumes.

From time to time, Diamond Offshore may enter into drilling contracts with national oil companies, government-controlled entities or others that expose it to greater risks than it normally assumes, such as exposure to greater environmental or other liability and more onerous termination provisions giving the customer a right to terminate without cause or upon little or no notice. Upon termination, these contracts may not result in a payment to Diamond Offshore, or if a termination payment is required, it may not fully compensate Diamond Offshore for the loss of a contract. In addition, the early termination of a contract may result in a rig being idle for an extended period of time, which could adversely affect Diamond Offshore’s financial condition, results of operations and cash flows. While Diamond Offshore believes that the financial terms of these contracts and its operating safeguards in place may partially mitigate these risks, it can provide no assurance that the increased risk exposure will not have a material negative impact on future operations or financial results.

27

Table of Contents

Contracts for Diamond Offshore’s drilling rigs are generally fixed dayrate contracts, and increases in Diamond Offshore’s operating costs could adversely affect the profitability on those contracts.

Diamond Offshore’s contracts for its drilling rigs generally provide for the payment of a fixed dayrate per rig operating day, although some contracts do provide for a limited escalation in dayrate due to increased operating costs it incurs on the project. Many of Diamond Offshore’s operating costs, such as labor costs, are unpredictable and fluctuate based on events beyond its control. In addition, equipment repair and maintenance expenses fluctuate depending on the type of activity the rig is performing, the age and condition of the equipment and general market factors impacting relevant parts, components and services. The gross margin that Diamond Offshore realizes on these fixed dayrate contracts will fluctuate based on variations in its operating costs over the terms of the contracts. In addition, for contracts with dayrate escalation clauses, Diamond Offshore may not be able to fully recover increased or unforeseen costs from its customers. Diamond Offshore’s inability to recover these increased or unforeseen costs from its customers could materially and adversely affect its business.

Rig conversions, upgrades or newbuilds may be subject to delays and cost overruns.

From time to time, Diamond Offshore adds new capacity through conversions or upgrades to its existing rigs or through new construction, such as the harsh environment, ultra-deepwater semisubmersible rig, Ocean GreatWhite, which is currently under construction. Projects of this type are subject to risks of delay or cost overruns inherent in any large construction project resulting from numerous factors, including the following:

Failure to complete a rig upgrade or new construction on time, or failure to complete a rig conversion or new construction in accordance with its design specifications may, in some circumstances, result in the delay, renegotiation or cancellation of a drilling contract, resulting in a loss of contract drilling backlog and revenue to Diamond Offshore. If a drilling contract is terminated under these circumstances, Diamond Offshore may not be able to secure a replacement contract, or if it does secure a replacement contract, it may not contain equally favorable terms. In addition, impairment write-offs could result if a rig’s carrying value becomes excessive due to spending over budget on a newbuild construction project or major rig upgrade.

Table of Contents

Diamond Offshore’s business involves numerous operating hazards which could expose it to significant losses and significant damage claims. Diamond Offshore is not fully insured against all of these risks and its contractual indemnity provisions may not fully protect Diamond Offshore.

Diamond Offshore’s operations are subject to the significant hazards inherent in drilling for oil and gas offshore, such as blowouts, reservoir damage, loss of production, loss of well control, unstable or faulty sea floor conditions, fires and natural disasters such as hurricanes. The occurrence of any of these types of events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel, damage to producing or potentially productive oil and gas formations, and oil spillage, oil leaks, well blowouts and extensive uncontrolled fires, any of which could cause significant environmental damage. In addition, offshore drilling operations are subject to marine hazards, including capsizing, grounding, collision and loss or damage from severe weather. Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, failure of suppliers or subcontractors to perform or supply goods or services or personnel shortages. Any of the foregoing events could result in significant damage or loss to Diamond Offshore’s properties and assets or the properties and assets of others, injury or death to rig personnel or others, significant loss of revenues and significant damage claims against Diamond Offshore, which could have a material adverse effect on its business.

Diamond Offshore’s drilling contracts with its customers provide for varying levels of indemnity and allocation of liabilities between its customers and Diamond Offshore with respect to the hazards and risks inherent in, and damages or losses arising out of, its operations, and Diamond Offshore may not be fully protected. Diamond Offshore’s contracts with its customers generally provide that Diamond Offshore and its customers each assume liability for their respective personnel and property. Diamond Offshore’s contracts also generally provide that its customers assume most of the responsibility for and indemnify Diamond Offshore against loss, damage or other liability resulting from, among other hazards and risks, pollution originating from the well and subsurface damage or loss, while Diamond Offshore typically retains responsibility for and indemnifies its customers against pollution originating from the rig. However, in certain drilling contracts Diamond Offshore may not be fully indemnified by its customers for damage to their property and/or the property of their other contractors. In certain contracts Diamond Offshore may assume liability for losses or damages (including punitive damages) resulting from pollution or contamination caused by negligent or willful acts of commission or omission by Diamond Offshore, its suppliers and/or subcontractors, generally subject to negotiated caps on a per occurrence basis and/or on an aggregate basis for the term of the contract. In some cases, suppliers or subcontractors who provide equipment or services to Diamond Offshore may seek to limit their liability resulting from pollution or contamination. Diamond Offshore’s contracts are individually negotiated, and the levels of indemnity and allocation of liabilities in them can vary from contract to contract depending on market conditions, particular customer requirements and other factors existing at the time a contract is negotiated.

Additionally, the enforceability of indemnification provisions in Diamond Offshore’s contracts may be limited or prohibited by applicable law or may not be enforced by courts having jurisdiction, and Diamond Offshore could be held liable for substantial losses or damages and for fines and penalties imposed by regulatory authorities. The indemnification provisions of Diamond Offshore’s contracts may be subject to differing interpretations, and the laws or courts of certain jurisdictions may enforce such provisions while other laws or courts may find them to be unenforceable, void or limited by public policy considerations, including when the cause of the underlying loss or damage is Diamond Offshore’s gross negligence or willful misconduct, when punitive damages are attributable to Diamond Offshore or when fines or penalties are imposed directly against Diamond Offshore. The law with respect to the enforceability of indemnities varies from jurisdiction to jurisdiction and is unsettled under certain laws that are applicable to Diamond Offshore’s contracts. Current or future litigation in particular jurisdictions, whether or not Diamond Offshore is a party, may impact the interpretation and enforceability of indemnification provisions in its contracts. There can be no assurance that Diamond Offshore’s contracts with its customers, suppliers and subcontractors will fully protect it against all hazards and risks inherent in its operations. There can also be no assurance that those parties with contractual obligations to indemnify Diamond Offshore will be financially able to do so or will otherwise honor their contractual obligations.

Diamond Offshore maintains liability insurance, which includes coverage for environmental damage; however, because of contractual provisions and policy limits, Diamond Offshore’s insurance coverage may not adequately cover its losses and claim costs. In addition, certain risks such as pollution, reservoir damage and environmental risks are generally not fully insurable. Also, Diamond Offshore does not typically purchase loss-of-hire insurance to

29

Table of Contents

cover lost revenues when a rig is unable to work. Accordingly, it is possible that Diamond Offshore’s losses from the hazards it faces could have a material adverse effect on its business.

Diamond Offshore believes that the policy limit under its marine liability insurance is within the range that is customary for companies of its size in the offshore drilling industry and is appropriate for its business. However, if an accident or other event occurs that exceeds Diamond Offshore’s coverage limits or is not an insurable event under its insurance policies, or is not fully covered by contractual indemnity, it could have a material adverse effect on Diamond Offshore’s business. There can be no assurance that Diamond Offshore will continue to carry the insurance it currently maintains, that its insurance will cover all types of losses or that Diamond Offshore will be able to maintain adequate insurance in the future at rates it considers to be reasonable or that Diamond Offshore will be able to obtain insurance against some risks.

Diamond Offshore has elected to self-insure for physical damage to rigs and equipment caused by named windstorms in the GOM.

Because the amount of insurance coverage available to Diamond Offshore has been limited, and the cost for such coverage is substantial, Diamond Offshore self-insures for physical damage to rigs and equipment caused by named windstorms in the GOM. This results in a higher risk of losses, which could be material, that are not covered by third party insurance contracts.

In addition, certain of Diamond Offshore’s shore-based facilities are located in geographic regions that are susceptible to damage or disruption from hurricanes and other weather events. Future hurricanes or similar natural disasters that impact Diamond Offshore’s facilities, its personnel located at those facilities or its ongoing operations may negatively affect its business for those periods. These negative effects may include reduced or lost sales and revenues; costs associated with interruption in operations and with resuming operations; reduced demand for Diamond Offshore’s services from customers that were similarly affected by these events; lost market share; late deliveries; uninsured property losses; inadequate business interruption insurance; employee evacuations; and an inability to retain necessary staff.

Significant portions of Diamond Offshore’s operations are conducted outside the United States and involve additional risks not associated with United States domestic operations.

Diamond Offshore’s operations outside the United States accounted for approximately 79%, 85% and 89% of its total consolidated revenues for 2015, 2014 and 2013 and include operations in South America, Australia and Southeast Asia, Europe, East and West Africa, the Mediterranean and Mexico. Because Diamond Offshore operates in various regions throughout the world, it is exposed to risks of war, political disruption, civil disturbance, acts of terrorism, political corruption, possible economic and legal sanctions (such as possible restrictions against countries that the U.S. government may consider to be state sponsors of terrorism) and changes in global trade policies. Diamond Offshore may not have insurance coverage for these risks, or it may not be able to obtain adequate insurance coverage for such events at reasonable rates. Diamond Offshore’s operations may become restricted, disrupted or prohibited in any country in which any of the foregoing risks occur. In particular, the occurrence of any of these risks or any of the following events could materially and adversely impact Diamond Offshore’s business:

30

Table of Contents

Diamond Offshore is also subject to the U.S. Treasury Department’s Office of Foreign Assets Control and other U.S. laws and regulations governing its international operations in addition to worldwide anti-bribery laws. In addition, international contract drilling operations are subject to various laws and regulations in countries in which Diamond Offshore operates, including laws and regulations relating to:

Some foreign governments favor or effectively require the awarding of drilling contracts to local contractors, require use of a local agent or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. These practices may adversely affect Diamond Offshore’s ability to compete in those regions. It is difficult to predict what governmental regulations may be enacted in the future that could adversely affect the international offshore drilling industry. The actions of foreign governments may materially and adversely affect Diamond Offshore’s ability to compete.

31

Table of Contents

In addition, the shipment of goods, including the movement of a drilling rig across international borders, subjects Diamond Offshore to extensive trade laws and regulations. Diamond Offshore’s import activities are governed by unique customs laws and regulations that differ in each of the countries in which Diamond Offshore operates and often impose record keeping and reporting obligations. The laws and regulations concerning import/export activity and record keeping and reporting requirements are complex and change frequently. These laws and regulations may be enacted, amended, enforced and/or interpreted in a manner that could materially and adversely impact Diamond Offshore’s operations. Shipments can be delayed and denied export or entry for a variety of reasons, some of which may be outside of Diamond Offshore’s control. Shipping delays or denials could cause unscheduled downtime for rigs. Failure to comply with these laws and regulations could result in criminal and civil penalties, economic sanctions, seizure of shipments and/or the contractual withholding of monies owed to Diamond Offshore, among other things.

Diamond Offshore may be required to accrue additional tax liability on certain of its foreign earnings.

Certain of Diamond Offshore’s international rigs are owned and operated, directly or indirectly, by Diamond Foreign Asset Company (“DFAC”), a Cayman Islands subsidiary that it owns. It is Diamond Offshore’s intention to indefinitely reinvest future earnings of DFAC and its foreign subsidiaries to finance foreign activities. Diamond Offshore does not expect to provide for U.S. taxes on any future earnings generated by DFAC and its foreign subsidiaries, except to the extent that these earnings are immediately subjected to U.S. federal income tax. Should a future distribution be made from any unremitted earnings of this subsidiary, Diamond Offshore may be required to record additional U.S. income taxes, that, if material, could have a material adverse effect on Diamond Offshore’s business.

Fluctuations in exchange rates and nonconvertibility of currencies could result in losses.

Due to Diamond Offshore’s international operations, Diamond Offshore has experienced currency exchange losses where revenues are received and expenses are paid in nonconvertible currencies or where it does not effectively hedge an exposure to a foreign currency. Diamond Offshore may also incur losses as a result of an inability to collect revenues because of a shortage of convertible currency available to the country of operation, controls over currency exchange or controls over the repatriation of income or capital.

Diamond Offshore relies on third-party suppliers, manufacturers and service providers to secure equipment, components and parts used in rig operations, conversions, upgrades and construction.

Diamond Offshore’s reliance on third-party suppliers, manufacturers and service providers to provide equipment and services exposes it to volatility in the quality, price and availability of such items. Certain components, parts and equipment that are used in Diamond Offshore’s operations may be available only from a small number of suppliers, manufacturers or service providers. The failure of one or more third-party suppliers, manufacturers or service providers to provide equipment, components, parts or services, whether due to capacity constraints, production or delivery disruptions, price increases, quality control issues, recalls or other decreased availability of parts and equipment, is beyond Diamond Offshore’s control and could materially disrupt its operations or result in the delay, renegotiation or cancellation of drilling contracts, thereby causing a loss of contract drilling backlog and/or revenue, as well as an increase in operating costs.

Additionally, Diamond Offshore’s suppliers, manufacturers and service providers could be negatively impacted by current industry conditions or global economic conditions. If certain of Diamond Offshore’s suppliers, manufacturers or service providers were to experience significant cash flow issues, become insolvent or otherwise curtail or discontinue their business as a result of such conditions, it could result in a reduction or interruption in supplies or equipment available to Diamond Offshore and/or a significant increase in the price of such supplies and equipment, which could adversely impact Diamond Offshore’s business.

Risks Related to Us and Our Subsidiary, Boardwalk Pipeline Partners, LP

Boardwalk Pipeline’s actual construction and development costs could exceed its forecast, and its cash flow from construction and development projects may not be immediate, which may limit its ability to maintain or increase cash distributions.

Boardwalk Pipeline is engaged in multiple significant construction projects involving existing and new assets for which it has expended or will expend significant capital and it expects to engage in additional growth projects of this type. The construction of new assets involves regulatory, environmental, legal, political, materials and labor cost, operational and other risks that are difficult to predict and beyond Boardwalk Pipeline’s control. Any of these projects may not be completed on time or at all, may be impacted by significant cost overruns or may be materially changed prior to completion as a result of developments or circumstances that Boardwalk Pipeline is not aware of when it commits to the project, including the ability of any foundation shipper to provide adequate credit support or to otherwise perform their obligations under any precedent agreements. Any of these factors could result in material unexpected costs or have a material adverse effect on Boardwalk Pipeline’s ability to realize the anticipated benefits from its growth projects.

Boardwalk Pipeline’s revenues and cash flows may not increase immediately on its expenditure of funds on a particular project. For example, if Boardwalk Pipeline builds a new pipeline or expands an existing facility, the design, construction and development may occur over an extended period of time and Boardwalk Pipeline may not receive any increase in revenue or cash flow from that project until after it is placed in service and customers begin using the new facilities.

Boardwalk Pipeline is exposed to credit risk relating to nonperformance by its customers.

Credit risk relates to the risk of loss resulting from the nonperformance by a customer of its contractual obligations. Credit risk exists in relation to Boardwalk Pipeline’s growth projects, both because foundation shippers have made long term commitments to Boardwalk Pipeline for capacity on such projects and certain of the foundation shippers have agreed to provide credit support as construction progresses. If a foundation shipper fails to meet the contractual credit requirements, an adjustment to the scope of the project could occur to accommodate a reduced volume commitment or Boardwalk Pipeline may be forced to find new customers to replace the defaulting customer, which could reduce the returns on the project. Boardwalk Pipeline’s exposure also relates to receivables for services provided, future performance under firm agreements and volumes of gas owed by customers for imbalances or gas loaned by it to them under certain NNS and PAL services.

Boardwalk Pipeline relies on a limited number of customers for a significant portion of revenues. For 2015, no one customer comprised more than 10% of its operating revenues, and the top ten customers comprised approximately 45% of revenues. If any of Boardwalk Pipeline’s significant customers have credit or financial problems which result in a delay or failure to pay for services provided by Boardwalk Pipeline or contracted for with them, to post the required credit support for construction associated with its growth projects or to repay the gas they owe Boardwalk Pipeline, it could have a material adverse effect on its business. In addition, Boardwalk Pipeline’s FERC gas tariffs only allow it to require limited credit support in the event that transportation customers are unable to pay for Boardwalk Pipeline’s services.

Natural gas producers comprise a significant portion of Boardwalk Pipeline’s revenues and support several of its growth projects. For example, in 2015, approximately 50% of Boardwalk Pipeline’s revenues were generated from contracts with natural gas producers. During 2015, the prices of oil and natural gas declined significantly from an increase in supplies mainly from shale production areas in the U.S. Should the prices of natural gas and oil remain at current levels for a sustained period of time, or decline further, Boardwalk Pipeline could be exposed to increased credit risk associated with its producer customer group, which would adversely impact Boardwalk Pipeline’s business.

33

Table of Contents

Boardwalk Pipeline may not be able to replace expiring natural gas transportation contracts at attractive rates or on a long-term basis and may not be able to sell short-term services at attractive rates or at all due to market conditions such as narrower basis differentials and sustained changes in the levels of natural gas and oil prices which adversely affect the value of its transportation services.

Transportation rates Boardwalk Pipeline is able to charge customers are heavily influenced by longer-term trends in, for example, the amount and geographical location of natural gas production and demand for gas by end-users such as power plants, petrochemical facilities and LNG export facilities. As a result of changes in longer-term trends, a sustained narrowing of basis differentials corresponding to traditional flow patterns on Boardwalk Pipeline’s pipeline systems (generally south to north and west to east) has occurred, reducing the transportation rates and adversely impacting other contract terms Boardwalk Pipeline can negotiate with its customers for available transportation capacity and for contracts scheduled for renewal.

Each year, a portion of Boardwalk Pipeline’s firm natural gas transportation contracts expire and need to be renewed or replaced. Over the past several years, Boardwalk Pipeline has renewed many expiring contracts at lower rates and for shorter terms than in the past, or not at all. Boardwalk Pipeline expects this trend to continue, mainly for contracts to transport gas from west to east across its system, and therefore, it may not be able to sell its available capacity, extend expiring contracts with existing customers or obtain replacement contracts at attractive rates or for the same term as the expiring contracts. The prevailing market conditions may also lead some of Boardwalk Pipeline’s customers, particularly customers that are experiencing financial difficulties, to seek to renegotiate existing contracts to terms that are less attractive to it. These sustained conditions have had, and Boardwalk Pipeline expects will continue to have, a materially adverse effect on revenues, earnings and distributable cash flows.

In 2008 and 2009, Boardwalk Pipeline placed into service a number of large new pipelines and expansions of its system, including its East Texas Pipeline, Southeast Expansion, Gulf Crossing Pipeline, and Fayetteville and Greenville Laterals. These projects were supported by firm transportation agreements with anchor shippers, typically having a term of ten years and pricing and other terms negotiated based on then current market conditions, which included wider basis spreads and, correspondingly, higher transportation rates than those prevailing in the current market. As a result, in 2018 and 2019, Boardwalk Pipeline will have significantly more transportation contract expirations than other years. Boardwalk Pipeline cannot predict what market conditions will prevail at the time such contracts expire, but if the contracts are renewed, it expects that these contracts will renew at lower transportation rates than when the contracts were initially executed. For example, if these contracts were renewed at current transportation market rates, revenues earned from these transportation contracts would be materially lower. If Boardwalk Pipeline is unable to renew or replace these and other expiring contracts when they expire, or if the terms of any such renewal or replacement contracts are not as favorable as the expiring agreements, its revenues and cash flows could be materially adversely affected. These market factors and conditions could materially impact Boardwalk Pipeline’s business.

Changes in energy prices, including natural gas, oil and NGLs, impact supply of and demand for those commodities, which impact Boardwalk Pipeline’s business.

Boardwalk Pipeline’s business is not significantly impacted by the short-term change in commodity prices, however, its customers, a significant amount of which are producers, are directly impacted by changes in commodity prices, which can impact Boardwalk Pipeline’s ability to renew contracts at existing capacities or rates or impact the producer’s ability to make payment for the services it provides. The prices of natural gas, oil and NGLs fluctuate in response to changes in supply and demand, market uncertainty and a variety of additional factors. If the recent dramatic declines in the levels of natural gas, oil and NGLs prices mentioned above were to continue for a sustained period of time, the businesses of Boardwalk Pipeline’s producer customer group would be adversely affected which, in turn, would reduce the demand for Boardwalk Pipeline’s services and could result in defaults or the non-renewal of contracted capacity when existing contracts expire. Conversely, future increases in the price of natural gas and NGLs could make alternative energy and feedstock sources more competitive and reduce demand for natural gas and NGLs. A reduced level of demand for natural gas and NGLs could reduce the utilization of capacity on Boardwalk Pipeline’s systems, reduce the demand for its services and could result in the non-renewal of contracted capacity as contracts expire and adversely impact its revenues, earnings and distributable cash flow.

Legislative and regulatory initiatives relating to pipeline safety that require the use of new or more stringent safety controls, substantial changes to existing integrity management programs, or more stringent enforcement of applicable legal requirements could subject Boardwalk Pipeline to increased capital and operating costs and operational delays.

Boardwalk Pipeline’s pipelines are subject to regulation by PHMSA of the DOT under the NGPSA with respect to natural gas and the HLPSA with respect to NGLs. The NGPSA and HLPSA govern the design, installation, testing, construction, operation, replacement and management of natural gas and NGLs pipeline facilities. These laws have resulted in the adoption of rules by PHMSA, that, among other things, require transportation pipeline operators to implement integrity management programs, including more frequent inspections, correction of identified anomalies and other measures to ensure pipeline safety in high consequence areas (HCAs), such as high population areas, areas unusually sensitive to environmental damage and commercially navigable waterways. In addition, states have adopted regulations similar to existing PHMSA regulations for certain intrastate natural gas and hazardous liquid pipelines, which regulations may impose more stringent requirements than found under federal law. Compliance with these rules has resulted in an overall increase in maintenance costs. New laws or regulations adopted by PHMSA may impose more stringent requirements applicable to integrity management programs and other pipeline safety aspects of Boardwalk Pipeline’s operations, which could cause it to incur increased capital and operating costs and operational delays.

The NGPSA and HLPSA were most recently updated by the 2011 Act, which was signed into law in early 2012. Under the 2011 Act, maximum civil penalties for certain violations have been increased to $200,000 per violation per day, with a total cap of $2.0 million. The 2011 Act reauthorized the federal pipeline safety programs of PHMSA through 2015, and directs the Secretary of Transportation to undertake a number of reviews, studies and reports, some of which may result in more stringent safety controls or inspections or additional natural gas and hazardous liquids pipeline safety rulemaking. Among other things, the 2011 Act directed the Secretary of Transportation to promulgate rules relating to expanded integrity management requirements, automatic or remote-controlled valve use, excess flow valve use, leak detection system installation, pipeline material strength testing and verification of maximum allowable pressures of certain pipelines. Although a number of the mandates imposed under the 2011 Act have yet to be acted upon by PHMSA, the provisions of the 2011 Act continue to have the potential to cause owners and operators of pipeline facilities to incur significant capital expenditures and/or operating costs. New pipeline safety legislation that will reauthorize the federal pipeline safety programs of PHMSA through 2019 will be under consideration. Passage of new legislation reauthorizing the PHMSA pipeline safety programs is expected to require, among other things, pursuit of those legal mandates included in the 2011 Act but not acted upon by PHMSA.

Further, Boardwalk Pipeline has entered into firm transportation contracts with shippers that utilize the design capacity of certain of pipeline assets, assuming that Boardwalk Pipeline operates those pipeline assets at higher than normal operating pressures of up to 0.80 of the pipeline’s SMYS. Boardwalk Pipeline has authority from PHMSA to operate those pipeline assets at such higher pressures; however, PHMSA retains discretion to withdraw or modify this authority. If PHMSA were to withdraw or materially modify such authority, Boardwalk Pipeline may not be able to transport all of its contracted quantities of natural gas on its pipeline assets and could incur significant additional costs to re-obtain such authority or to develop alternate ways to meet its contractual obligations.

Boardwalk Pipeline may not continue making distributions to unitholders at the current distribution rate, or at all.

The amount of cash Boardwalk Pipeline has available to distribute to its unitholders principally depends upon the amount of cash it generates from its operations and financing activities and the amount of cash it requires, or determines to use, for other purposes, all of which fluctuate from quarter to quarter based on a number of factors, many of which are beyond the control of Boardwalk Pipeline. Some of the factors that influence the amount of cash Boardwalk Pipeline has available for distribution in any quarter include:

Table of Contents

There is no guarantee that unitholders will receive quarterly distributions from Boardwalk Pipeline. Boardwalk Pipeline’s distributions are determined each quarter by the board of directors of its general partner based on the board’s consideration of Boardwalk Pipeline’s financial position, earnings, cash flow, current and future business needs and other relevant factors at that time. Boardwalk Pipeline may reduce or eliminate distributions at any time it determines that its cash reserves are insufficient or are otherwise required to fund current or anticipated future operations, capital expenditures, acquisitions, growth or expansion projects, debt repayment or other business needs.

Boardwalk Pipeline may not be successful in executing its strategy to grow and diversify its business.

Boardwalk Pipeline relies primarily on the revenues generated from its long-haul natural gas transportation and storage services. As a result, negative developments in these services have significantly greater impact on Boardwalk Pipeline’s financial condition and results of operations than if it maintained more diverse assets. Boardwalk Pipeline is pursuing a strategy of growing and diversifying its business through acquisition and development of assets in complementary areas of the midstream energy sector, such as liquids transportation and storage assets, among others. Boardwalk Pipeline’s ability to grow, diversify and increase distributable cash flows will depend, in part, on its ability to close and execute on accretive acquisitions and projects. Boardwalk Pipeline may not be successful in acquiring or developing such assets or may do so on terms that ultimately are not profitable. Any such transactions involve potential risks that may include, among other things:

36

Table of Contents

Additionally, acquisitions contain the following risks:

There is no certainty that Boardwalk Pipeline will be able to complete these acquisitions or projects on schedule, on budget or at all.

Boardwalk Pipeline may not be able to replace expiring gas storage contracts at attractive rates or on a long-term basis and may not be able to sell short-term services at attractive rates or at all due to a sustained narrowing of price spreads between time periods and reduced volatility which adversely affect Boardwalk Pipeline’s storage services.

Boardwalk Pipeline owns and operates substantial natural gas storage facilities. The market for the storage and PAL services that it offers is impacted by the factors and market conditions discussed above for Boardwalk Pipeline’s transportation services, and is also impacted by natural gas price differentials between time periods, such as winter to summer (time period price spreads), and the volatility in time period price spreads. Market conditions have caused a sustained narrowing of time period price spreads and a sustained decline in the price volatility of natural gas, which has adversely impacted the rates Boardwalk Pipeline can charge for its storage and PAL services and the value associated with these services, especially when compared to previous historical levels. These market factors and conditions have adversely impacted Boardwalk Pipeline’s business.

Boardwalk Pipeline’s natural gas transportation and storage operations are subject to extensive regulation by FERC, including rules and regulations related to the rates it can charge for its services and its ability to construct or abandon facilities. FERC’s rate-making policies could limit its ability to recover the full cost of operating its pipelines, including earning a reasonable return.

Boardwalk Pipeline’s natural gas transportation and storage operations are subject to extensive regulation by FERC, including the types and terms of services Boardwalk Pipeline may offer to its customers, construction of new facilities, creation, modification or abandonment of services or facilities, recordkeeping and relationships with affiliated companies. FERC action in any of these areas could adversely affect Boardwalk Pipeline’s ability to compete for business, construct new facilities, offer new services or recover the full cost of operating its pipelines. This regulatory oversight can result in longer lead times to develop and complete any future project than competitors that are not subject to FERC’s regulations. FERC can also deny Boardwalk Pipeline the right to remove certain facilities from service.

FERC also regulates the rates Boardwalk Pipeline can charge for its natural gas transportation and storage operations. For cost-based services, FERC establishes both the maximum and minimum rates Boardwalk Pipeline can charge. The basic elements that FERC considers are the costs of providing service, the volumes of gas being transported, the rate design, the allocation of costs between services, the capital structure and the rate of return a pipeline is permitted to earn. Boardwalk Pipeline may not be able to earn a return or recover all of its costs, including certain costs associated with pipeline integrity activities, through existing or future rates. FERC can challenge the existing rates on any of Boardwalk Pipeline’s pipelines. Such a challenge against Boardwalk Pipeline could adversely affect its ability to charge rates that would cover future increases in its costs or even to continue to collect rates to maintain its current revenue levels that are designed to permit a reasonable opportunity to recover current costs and depreciation and earn a reasonable return.

Risks Related to Us and Our Subsidiaries Generally

In addition to the specific risks and uncertainties faced by our subsidiaries, as discussed above, we and all of our subsidiaries face risks and uncertainties related to, among other things, terrorism, hurricanes and other natural disasters, competition, government regulation, dependence on key executives and employees, litigation, dependence on information technology and compliance with environmental laws.

Acts of terrorism could harm us and our subsidiaries.

Future terrorist attacks and the continued threat of terrorism in this country or abroad, as well as possible retaliatory military and other action by the United States and its allies, could have a significant impact on the assets and businesses of certain of our subsidiaries. CNA issues coverages that are exposed to risk of loss from a terrorism act. Terrorist acts or the threat of terrorism, including increased political, economic and financial market instability and volatility in the price of oil and gas, could affect the market for Diamond Offshore’s drilling services and Boardwalk Pipeline’s transportation, gathering and storage services. In addition, future terrorist attacks could lead to reductions in business travel and tourism which could harm Loews Hotels. While our subsidiaries take steps that they believe are appropriate to secure their assets, there is no assurance that they can completely secure them against a terrorist attack or obtain adequate insurance coverage for terrorist acts at reasonable rates.

Changes in tax laws of jurisdictions in which we or our subsidiaries operate could adversely impact us.

Changes in federal, state or foreign tax laws applicable to us or our subsidiaries could materially and adversely impact our and our subsidiaries’ tax liability, financial condition, results of operations and cash flows, including the amount of cash our subsidiaries have available to distribute to their shareholders, including us. In particular, potential changes to tax laws governing tax credits or relating to the taxation of interest from municipal bonds, foreign earnings and publicly traded partnerships could have such adverse effects.

Our subsidiaries are subject to extensive federal, state and local governmental regulations.

The businesses operated by our subsidiaries are impacted by current and potential federal, state and local governmental regulations which impose or might impose a variety of restrictions and compliance obligations on those companies. Governmental regulations can also change materially in ways that could adversely affect those companies. Risks faced by our subsidiaries related to governmental regulation include the following:

CNA. The insurance industry is subject to comprehensive and detailed regulation and supervision. Most insurance regulations are designed to protect the interests of CNA’s policyholders and third-party claimants rather than its investors. Each jurisdiction in which CNA does business has established supervisory agencies that regulate its business, generally at the state level. Any changes in federal regulation could also impose significant burdens on CNA. In addition, the Lloyd’s marketplace sets rules under which its members, including CNA’s Hardy syndicate, operate.

These rules and regulations relate to, among other things, the standards of solvency (including risk-based capital measures), government-supported backstops for certain catastrophic events (including terrorism), investment restrictions, accounting and reporting methodology, establishment of reserves and potential assessments of funds to settle covered claims against impaired, insolvent or failed private or quasi-governmental insurers.

Regulatory powers also extend to premium rate regulations which require that rates not be excessive, inadequate or unfairly discriminatory. CNA may also be required by the jurisdictions in which it does business to provide coverage to persons who would not otherwise be considered eligible or restrict CNA from withdrawing from unprofitable lines of business or unprofitable market areas. Each jurisdiction dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. CNA’s share of these involuntary risks is mandatory and generally a function of its respective share of the voluntary market by line of insurance in each jurisdiction.

Diamond Offshore. Certain countries are subject to restrictions, sanctions and embargoes imposed by the United States government or other governmental or international authorities. These restrictions, sanctions and embargoes prohibit or limit Diamond Offshore from participating in certain business activities in those countries. Diamond Offshore’s operations are also subject to numerous local, state and federal laws and regulations in the United States and in foreign jurisdictions concerning the containment and disposal of hazardous materials, the remediation of contaminated properties and the protection of the environment. The offshore drilling industry is dependent on demand for services from the oil and gas exploration industry and, accordingly, can be affected by changes in tax and other laws relating to the energy business generally. Diamond Offshore may be required to make significant expenditures for additional capital equipment or inspections and recertifications to comply with governmental laws and regulations. It is also possible that these laws and regulations may, in the future, add significantly to Diamond Offshore’s operating costs or result in a reduction in revenues associated with downtime required to install such equipment, or may otherwise significantly limit drilling activity.

In addition, Diamond Offshore’s business is negatively impacted when it performs certain regulatory inspections, which Diamond Offshore refers to as a 5-year survey, or special survey, that are due every five years for each of its rigs. These special surveys are generally performed in a shipyard and require scheduled downtime, which can negatively impact operating revenue. Operating expenses increase as a result of these special surveys due to the cost to mobilize the rigs to a shipyard, inspection costs incurred and repair and maintenance costs. Repair and maintenance activities may result from the special survey or may have been previously planned to take place during this mandatory downtime. The number of rigs undergoing a 5-year survey will vary from year to year, as well as from quarter to quarter. Diamond Offshore’s business may also be negatively impacted by intermediate surveys, which are performed at interim periods between 5-year surveys. Intermediate surveys are generally less extensive in duration and scope than a 5-year survey. Although an intermediate survey normally does not require shipyard time, the survey may require some downtime for the rig. Diamond Offshore can provide no assurance as to the exact timing and/or duration of downtime associated with regulatory inspections, planned rig mobilizations and other shipyard projects.

In the aftermath of the 2010 Macondo well blowout and the subsequent investigation into the causes of the event, new rules were implemented for oil and gas operations in the GOM and in many of the international locations in which Diamond Offshore operates, including new standards for well design, casing and cementing and well control procedures, equipment inspections and certifications, as well as rules requiring operators to systematically identify risks and establish safeguards against those risks through a comprehensive safety and environmental management system (“SEMS”). New regulations may continue to be announced, including rules regarding drilling systems and equipment, such as blowout preventer and well control systems and lifesaving systems, as well as rules regarding employee training, engaging personnel in safety management and requiring third party audits of SEMS programs. Such new regulations could require modifications or enhancements to existing systems and equipment, or require new equipment, and could increase Diamond Offshore’s operating costs and cause downtime for its rigs if it is required to take any of them out of service between scheduled surveys or inspections, or if it is required to extend scheduled surveys or inspections, to meet any such new requirements. Diamond Offshore is not able to predict the likelihood, nature or extent of additional rulemaking, nor is it able to predict the future impact of these events on operations. Additional governmental regulations concerning licensing, taxation, equipment specifications, training requirements or other matters could increase the costs of Diamond Offshore’s operations, and enhanced permitting requirements, as well as escalating costs borne by its customers, could reduce exploration activity in the GOM and therefore demand for its services.

Governments in some countries are increasingly active in regulating and controlling the ownership of concessions, the exploration for oil and gas and other aspects of the oil and gas industry. The modification of existing laws or regulations or the adoption of new laws or regulations curtailing exploratory or developmental drilling for oil and gas for economic, environmental or other reasons could materially and adversely affect Diamond Offshore’s operations by limiting drilling opportunities.

Boardwalk Pipeline. Boardwalk Pipeline’s natural gas transportation and storage operations are subject to extensive regulation by FERC and PHMSA of the DOT among other federal and state authorities. In addition to FERC rules and regulations related to the rates Boardwalk Pipeline can charge for its services, federal regulations extend to pipeline safety, operating terms and conditions of service, the types of services Boardwalk Pipeline may offer, construction or abandonment of facilities, accounting and record keeping, and relationships and transactions

39

Table of Contents

with affiliated companies. These regulations can adversely impact Boardwalk Pipeline’s ability to compete for business, construct new facilities, including by increasing the lead times to develop projects, offer new services, or recover the full cost of operating its pipelines.

Our subsidiaries face significant risks related to compliance with environmental laws.

Our subsidiaries have extensive obligations and financial exposure related to compliance with federal, state and local environmental laws, many of which have become increasingly stringent in recent years and may in some cases impose strict liability, which could be substantial, rendering a person liable for environmental damage without regard to negligence or fault on the part of that person. For example, Diamond Offshore could be liable for damages and costs incurred in connection with oil spills related to its operations, including for conduct of or conditions caused by others. Boardwalk Pipeline is also subject to laws and regulations, including requiring the acquisition of permits or other approvals to conduct regulated activities, restricting the manner in which it disposes of waste, requiring remedial action to remove or mitigate contamination resulting from a spill or other release, requiring capital expenditures to comply with pollution control requirements.

We and our subsidiaries are subject to physical and financial risks associated with climate change.

The U.S. Congress and the Environmental Protection Agency (“EPA”) as well as some states and regional groupings of states have in recent years considered legislation or regulations to reduce emissions of Greenhouse Gas (“GHG”). In the absence of federal GHG-limiting legislation, the EPA had adopted rules under authority of the Clean Air Act that, among other things, establish Potential for Significant Deterioration (“PSD”) construction and Title V operating permit reviews for GHG emissions from certain large stationary sources that are also potential major sources of certain principal, or criteria, pollutant emissions, which reviews could require securing PSD permits at covered facilities emitting GHGs and meeting “best available control technology” standards for those GHG emissions. In addition, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the U.S., including, among others, onshore processing, transmission, storage and distribution facilities. In October 2015, the EPA published a final reporting rule for certain onshore gathering and boosting systems consisting primarily of gathering pipelines, compressors and process equipment used to perform natural gas compression, dehydration and acid gas removal.

Moreover, the EPA proposed in August 2015 rules that will establish emission standards for methane and volatile organic compounds released from new and modified oil and natural gas production and natural gas processing and transmissions facilities, as part of the current U.S. President administration’s efforts to reduce methane emissions from the oil and natural gas sector by up to 45 percent from 2012 levels by 2025. The EPA is expected to finalize those rules in 2016. Furthermore, the EPA has passed a rule, known as the Clean Power Plan, to limit GHGs from power plants, but on February 9, 2016, the U.S. Supreme Court stayed this rule while it is being challenged in the federal D.C. Circuit Court of Appeals. If this rule survives legal challenge, then depending on the methods used to implement this rule, it could reduce demand for the oil and natural gas that Boardwalk Pipeline’s customers produce. Although it is not possible at this time to predict how legislation or regulations that may be adopted to address GHG emissions would impact businesses of our energy subsidiaries, any such future laws and regulations could result in increased compliance costs or additional operating restrictions, and could have a material adverse effect on the businesses of our energy subsidiaries.

Any significant interruption in the operation of our facilities, systems and business functions or breach in our data security infrastructure could result in a materially adverse effect on our operations.

We and our subsidiaries have become more reliant on technology to help increase efficiency in our businesses. We are dependent upon operational and financial computer systems to process the data necessary to conduct almost all aspects of our businesses. Any failure of our or our subsidiaries’ computer systems, or those of our or their customers, vendors or others with whom we and they do business, could materially disrupt business operations. Computer and other business facilities and systems could become unavailable or impaired from a variety of causes, including among others, storms and other natural disasters, terrorist attacks, utility outages or complications encountered as existing systems are replaced or upgraded. In addition, it has been reported that unknown entities or groups have mounted so-called “cyber attacks” on businesses and other organizations solely to disable or disrupt

40

Table of Contents

computer systems, disrupt operations and, in some cases, steal data. Any cyber attacks that affect our or our subsidiaries’ facilities could have a material adverse effect on our and their business or reputation.

A significant breach of our data security infrastructure, resulting from actions by our employees, vendors, third party administrators or by unknown third parties, that impacts our data framework or causes a failure to protect personal information of customers or employees may result in operational impairments and financial losses, as well as significant harm to our reputation.

The foregoing risks relating to disruption of service, interruption of operations and data loss could expose us to monetary and reputational damages. In addition, potential exposure includes substantially increased compliance costs and requires computer system upgrades and security related investments. The breach of confidential information also could give rise to legal liability and regulatory action under data protection and privacy laws and regulations, both in the U.S. and foreign jurisdictions. Any such legal or regulatory action could have a material adverse effect on our operations.

Loss of key vendor relationships or issues relating to the transitioning of vendor relationships could result in a materially adverse effect on our and our subsidiaries’ operations.

We and our subsidiaries rely on services and products provided by many vendors in the United States and abroad. These include, for example, vendors of computer hardware, software and services, as well as other critical materials and services. If one or more key vendors becomes unable to continue to provide products or services at the requisite level, or fails to protect our proprietary information, including in some cases personal information of employees, customers or hotel guests, we and our subsidiaries may experience a material adverse effect on our or their business or reputation.

We could incur impairment charges related to the carrying value of the long-lived assets and goodwill of our subsidiaries.

Our subsidiaries regularly evaluate their long-lived assets and goodwill for impairment whenever events or changes in circumstances indicate the carrying value of these assets may not be recoverable. Most notably, we could incur impairment charges related to the carrying value of offshore drilling equipment at Diamond Offshore, pipeline and storage assets at Boardwalk Pipeline and hotel properties owned by Loews Hotels.

In particular, Diamond Offshore is currently experiencing declining demand for certain offshore drilling rigs as a result of excess rig supply in the industry due, in part, to the numerous newly constructed rigs that have or will enter the market. As a result, these rigs will negatively impact utilization which could result in Diamond Offshore incurring additional asset impairments, rig retirements and/or rigs being scrapped.

We test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. The goodwill impairment test requires us to identify reporting units and estimate each unit’s fair value as of the testing date. We calculate the fair value of our reporting units (each of our principal operating subsidiaries) based on estimates of future discounted cash flows, which reflect management’s judgments and assumptions regarding the appropriate risk-adjusted discount rate, future industry conditions and operations and other factors. Asset impairment evaluations are, by nature, highly subjective. The use of different estimates and assumptions could result in materially different carrying values of our assets which could impact the need to record an impairment charge and the amount of any charge taken.

We are a holding company and derive substantially all of our income and cash flow from our subsidiaries.

We rely upon our invested cash balances and distributions from our subsidiaries to generate the funds necessary to meet our obligations and to declare and pay any dividends to holders of our common stock. Our subsidiaries are separate and independent legal entities and have no obligation, contingent or otherwise, to make funds available to us, whether in the form of loans, dividends or otherwise. The ability of our subsidiaries to pay dividends to us is also subject to, among other things, the availability of sufficient earnings and funds in such subsidiaries, applicable state laws, including in the case of the insurance subsidiaries of CNA, laws and rules governing the payment of dividends by regulated insurance companies, and their compliance with covenants in their respective loan agreements. Claims

of creditors of our subsidiaries will generally have priority as to the assets of such subsidiaries over our claims and our creditors and shareholders.

We could have liability in the future for tobacco-related lawsuits.

As a result of our ownership of Lorillard, Inc. (“Lorillard”) prior to the separation of Lorillard from us in 2008 (the “Separation”), from time to time we have been named as a defendant in tobacco-related lawsuits and could be named as a defendant in additional tobacco-related suits, notwithstanding the completion of the Separation. In the Separation Agreement entered into between us and Lorillard and its subsidiaries in connection with the Separation, Lorillard and each of its subsidiaries has agreed to indemnify us for liabilities related to Lorillard’s tobacco business, including liabilities that we may incur for current and future tobacco-related litigation against us. An adverse decision in a tobacco-related lawsuit against us could, if the indemnification is deemed for any reason to be unenforceable or any amounts owed to us thereunder are not collectible, in whole or in part, have a material adverse effect on our financial condition, results of operations and equity. We do not expect that the Separation will alter the legal exposure of either entity with respect to tobacco-related claims. We do not believe that we have any liability for tobacco-related claims, and we have never been held liable for any such claims.

The following discussion should be read in conjunction with Item 1A, Risk Factors, and Item 8, Financial Statements and Supplementary Data of this Form 10-K.

Consolidated Financial Results

Consolidated net income for 2015 was $260 million, or $0.72 per share, compared to $591 million, or $1.55 per share, in 2014. Net income in 2014 included discontinued operations reflecting the sale of HighMount Exploration & Production, LLC (“HighMount”) and CNA’s former life insurance subsidiary.

Income from continuing operations for 2015 was $260 million, or $0.72 per share, compared to $962 million, or $2.52 per share, in 2014. The decline in income from continuing operations was primarily due to a reserve charge at CNA and asset impairment charges at Diamond Offshore. In addition, parent company investment income declined as a result of lower performance of equity securities in the trading portfolio and decreased results from limited partnership investments.

CNA’s earnings decreased primarily due to a reserve charge of $177 million (after tax and noncontrolling interests) resulting from the unlocking of actuarial assumptions related to future policy benefit reserves for the long term care business. Excluding this charge, CNA’s earnings declined year-over-year primarily due to lower limited partnership results and a $38 million charge (after tax and noncontrolling interests) related to a retroactive reinsurance agreement to cede its legacy asbestos and environmental pollution liabilities. This earnings decline was partially offset by improved underwriting results driven by higher favorable net prior year development.

Diamond Offshore’s results for 2015 include asset impairment charges totaling $341 million (after tax and noncontrolling interests) related to the carrying value of 17 drilling rigs, as well as lower rig utilization. In addition, earnings were impacted by a $20 million impairment charge to write off all goodwill associated with the Company’s investment in Diamond Offshore as well as increased depreciation and interest expense. In 2014, Diamond Offshore recognized an asset impairment charge of $55 million (after tax and noncontrolling interests).

Boardwalk Pipeline’s earnings increase primarily stemmed from the impact of a $55 million charge (after tax and noncontrolling interests) in 2014 related to the write off of all capitalized costs associated with the terminated Bluegrass project. Absent this charge, earnings were largely consistent with the prior year as additional revenues from the settlement of the Gulf South rate case and a franchise tax refund related to settlement of prior tax periods were offset by lower natural gas storage revenues and increased depreciation and interest costs.

47

Table of Contents

Loews Hotels’ earnings increased slightly as compared to the prior year as higher income from Universal Orlando joint venture properties was partially offset by higher interest expense and increased tax expense due to an adjustment for prior years’ estimates and higher Florida state income taxes, reflecting increased profits at the Universal Orlando and Miami properties.

Book value per share decreased to $51.67 at December 31, 2015 from $51.70 at December 31, 2014. Book value per share excluding Accumulated other comprehensive income (“AOCI”) increased to $52.72 at December 31, 2015 from $50.95 at December 31, 2014.

Parent Company Structure

We are a holding company and derive substantially all of our cash flow from our subsidiaries. We rely upon our invested cash balances and distributions from our subsidiaries to generate the funds necessary to meet our obligations and to declare and pay any dividends to our shareholders. The ability of our subsidiaries to pay dividends is subject to, among other things, the availability of sufficient earnings and funds in such subsidiaries, applicable state laws, including in the case of the insurance subsidiaries of CNA, laws and rules governing the payment of dividends by regulated insurance companies (see Note 13 of the Notes to Consolidated Financial Statements included under Item 8) and compliance with covenants in their respective loan agreements. Claims of creditors of our subsidiaries will generally have priority as to the assets of such subsidiaries over our claims and those of our creditors and shareholders.

CRITICAL ACCOUNTING ESTIMATES

The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and the related notes. Actual results could differ from those estimates.

The Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP, applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third party professionals and various other assumptions that we believe are reasonable under the known facts and circumstances.

We consider the accounting policies discussed below to be critical to an understanding of our Consolidated Financial Statements as their application places the most significant demands on our judgment. Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from estimates, which may have a material adverse impact on our results of operations and/or equity.

Insurance Reserves

Insurance reserves are established for both short and long-duration insurance contracts. Short-duration contracts are primarily related to property and casualty insurance policies where the reserving process is based on actuarial estimates of the amount of loss, including amounts for known and unknown claims. Long-duration contracts are primarily related to long term care and are estimated using actuarial estimates about morbidity and persistency as well as assumptions about expected investment returns and future premium rate increases. The reserve for unearned premiums on property and casualty contracts represents the portion of premiums written related to the unexpired terms of coverage. The reserving process is discussed in further detail in the Reserves – Estimates and Uncertainties section below.

Reinsurance and Other Receivables

An exposure exists with respect to the collectibility of ceded property and casualty and life reinsurance to the extent that any reinsurer is unable to meet its obligations or disputes the liabilities CNA has ceded under reinsurance agreements. An allowance for doubtful accounts on reinsurance receivables is recorded on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, CNA’s past experience and current economic

48

Table of Contents

conditions. Further information on CNA’s reinsurance receivables is included in Note 15 of the Notes to Consolidated Financial Statements included under Item 8.

Additionally, an exposure exists with respect to the collectibility of amounts due from customers on other receivables. An allowance for doubtful accounts is recorded on the basis of periodic evaluations of balances currently due as well as in the future, management’s experience and current economic conditions.

If actual experience differs from the estimates made by management in determining the allowances for doubtful accounts on reinsurance and other receivables, net receivables as reflected on our Consolidated Balance Sheets may not be collected. Therefore, our results of operations and/or equity could be materially adversely affected.

Valuation of Investments and Impairment of Securities

We classify fixed maturity securities and equity securities as either available-for-sale or trading which are both carried at fair value. Fair value represents the price that would be received in a sale of an asset in an orderly transaction between market participants on the measurement date, the determination of which requires us to make a significant number of assumptions and judgments. Securities with the greatest level of subjectivity around valuation are those that rely on inputs that are significant to the estimated fair value and that are not observable in the market or cannot be derived principally from or corroborated by observable market data. These unobservable inputs are based on assumptions consistent with what we believe other market participants would use to price such securities. Further information on fair value measurements is included in Note 4 of the Notes to Consolidated Financial Statements included under Item 8.

CNA’s investment portfolio is subject to market declines below amortized cost that may be other-than-temporary and therefore result in the recognition of impairment losses in earnings. Factors considered in the determination of whether or not a decline is other-than-temporary include a current intention or need to sell the security or an indication that a credit loss exists. Significant judgment exists regarding the evaluation of the financial condition and expected near-term and long term prospects of the issuer, the relevant industry conditions and trends, and whether CNA expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. Further information on CNA’s process for evaluating impairments is included in Note 1 of the Notes to Consolidated Financial Statements included under Item 8.

Long Term Care Policies

Future policy benefit reserves for CNA’s long term care policies are based on certain assumptions including morbidity, persistency, discount rates and future premium rate increases. The adequacy of the reserves is contingent on actual experience related to these key assumptions. If actual experience differs from these assumptions, the reserves may not be adequate, requiring CNA to add to reserves.

A prolonged period during which interest rates remain at levels lower than those anticipated in CNA’s reserving discount rate assumption could result in shortfalls in investment income on assets supporting CNA’s obligations under long term care policies, which may also require an increase to CNA’s reserves. In addition, CNA may not receive regulatory approval for the premium rate increases it requests.

These changes to CNA’s reserves could materially adversely impact our results of operations and equity. The reserving process is discussed in further detail in the Reserves – Estimates and Uncertainties section below.

Pension and Postretirement Benefit Obligations

We make a significant number of assumptions in order to estimate the liabilities and costs related to our pension and postretirement benefit obligations under our benefit plans. The assumptions that have the most impact on pension costs are the discount rate and the expected long term rate of return on plan assets. These assumptions are evaluated relative to current market factors such as inflation, interest rates and broader capital market expectations. Changes in these assumptions can have a material impact on pension obligations and pension expense.

Table of Contents

In determining the discount rate assumption, we utilized current market information and liability information, including a discounted cash flow analysis of our pension and postretirement obligations. In particular, the basis for our discount rate selection was the yield on indices of highly rated fixed income debt securities with durations comparable to that of our plan liabilities. The yield curve was applied to expected future retirement plan payments to adjust the discount rate to reflect the cash flow characteristics of the plans. The yield curves and indices evaluated in the selection of the discount rate are comprised of high quality corporate bonds that are rated AA by an accepted rating agency.

In determining the expected long term rate of return on plan assets assumption, we considered the historical performance of the investment portfolio as well as the long term market return expectations based on the investment mix of the portfolio and the expected investment horizon.

Further information on our pension and postretirement benefit obligations is in Note 14 of the Notes to Consolidated Financial Statements included under Item 8.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment when changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company uses a probability-weighted cash flow analysis to test property and equipment for impairment based on relevant market data. If an asset is determined to be impaired, a loss is recognized to reduce the carrying amount to the fair value of the asset. Management’s cash flow assumptions are an inherent part of our asset impairment evaluation and the use of different assumptions could produce results that differ from the reported amounts.

Goodwill

Goodwill is required to be evaluated on an annual basis and whenever, in management’s judgment, there is a significant change in circumstances that would be considered a triggering event. Management must apply judgment in assessing qualitatively whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Factors such as a reporting unit’s planned future operating results, long term growth outlook and industry and market conditions are considered. Judgment is also applied in determining the estimated fair value of reporting units’ assets and liabilities for purposes of performing quantitative goodwill impairment tests. Management uses all available information to make these fair value determinations, including the present values of expected future cash flows using discount rates commensurate with the risks involved in the assets and observed market multiples.

Income Taxes

Deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities. Any resulting future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes may not be realized. The assessment of the need for a valuation allowance requires management to make estimates and assumptions about future earnings, reversal of existing temporary differences and available tax planning strategies. If actual experience differs from these estimates and assumptions, the recorded deferred tax asset may not be fully realized, resulting in an increase to income tax expense in our results of operations. In addition, the ability to record deferred tax assets in the future could be limited resulting in a higher effective tax rate in that future period.

The Company has not established deferred tax liabilities for certain of its foreign earnings as it intends to indefinitely reinvest those earnings to finance foreign activities. However, if these earnings become subject to U.S. federal tax, any required provision could have a material impact on our financial results.

Reserves – Estimates and Uncertainties

The level of reserves CNA maintains represents its best estimate, as of a particular point in time, of what the ultimate settlement and administration of claims will cost based on CNA’s assessment of facts and circumstances known at that time. Reserves are not an exact calculation of liability but instead are complex estimates that CNA derives, generally utilizing a variety of actuarial reserve estimation techniques, from numerous assumptions and expectations about future events, both internal and external, many of which are highly uncertain. As noted below, CNA reviews its reserves for each segment of its business periodically and any such review could result in the need to increase reserves in amounts which could be material and could adversely affect its results of operations, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note 8 of the Notes to Consolidated Financial Statements included under Item 8.

Property and Casualty Claim and Claim Adjustment Expense Reserves

CNA maintains loss reserves to cover its estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for claims that have been reported but not yet settled (case reserves) and claims that have been incurred but not reported (“IBNR”). Claim and claim adjustment expense reserves are reflected as liabilities and are included on the Consolidated Balance Sheets under the heading “Insurance Reserves.” Adjustments to prior year reserve estimates, if necessary, are reflected in results of operations in the period that the need for such adjustments is determined. The carried case and IBNR reserves as of each balance sheet date are provided in the discussion that follows and in Note 8 of the Notes to Consolidated Financial Statements included under Item 8.

CNA is subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on CNA’s business by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims.

Emerging or potential claims and coverage issues include, but are not limited to, uncertainty in future medical costs in workers’ compensation. In particular, medical cost inflation could be greater than expected due to new treatments, drugs and devices, increased health care utilization and/or the future costs of health care facilities. In addition, the relationship between workers’ compensation and government and private health care providers could change, potentially shifting costs to workers’ compensation.

The impact of these and other unforeseen emerging or potential claims and coverage issues is difficult to predict and could materially adversely affect the adequacy of CNA’s claim and claim adjustment expense reserves and could lead to future reserve additions.

CNA’s property and casualty insurance subsidiaries also have actual and potential exposures related to asbestos and environmental pollution (“A&EP”) claims. CNA’s experience has been that establishing reserves for casualty coverages relating to A&EP claims and the related claim adjustment expenses are subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability.

To mitigate the risks posed by CNA’s exposure to A&EP claims and claim adjustment expenses, CNA completed a transaction with National Indemnity Company (“NICO”), under which substantially all of CNA’s legacy A&EP liabilities were ceded to NICO effective January 1, 2010 (loss portfolio transfer or “LPT”).

51

Table of Contents

The loss portfolio transfer is a retroactive reinsurance contract. The cumulative amounts ceded under the loss portfolio transfer exceed the consideration paid, therefore CNA has recognized a deferred retroactive reinsurance gain. This deferred gain is recognized in earnings in proportion to actual recoveries under the loss portfolio transfer. Over the life of the contract, there is no economic impact as long as any additional losses are within the limit of the contract.

See Note 8 of the Notes to the Consolidated Financial Statements included under Item 8 for further discussion of the loss portfolio transfer, its impact on CNA’s results of operations and the deferred retroactive reinsurance gain.

Historically, CNA performed its actuarial review of A&EP claims in the fourth quarter. In 2014, CNA was unable to complete the fourth quarter review because it determined that additional information and analysis of inuring third-party reinsurance recoveries was required. The reserve review was completed in the second quarter of 2015 and CNA management adopted the second quarter of the year as the timing for all future annual A&EP claims actuarial reviews.

Establishing Property & Casualty Reserve Estimates

In developing claim and claim adjustment expense (“loss” or “losses”) reserve estimates, CNA’s actuaries perform detailed reserve analyses that are staggered throughout the year. The data is organized at a reserve group level. A reserve group can be a line of business covering a subset of insureds such as commercial automobile liability for small or middle market customers, it can encompass several lines of business provided to a specific set of customers such as dentists, or it can be a particular type of claim such as construction defect. Every reserve group is reviewed at least once during the year. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. In addition to the detailed analyses, CNA reviews actual loss emergence for all products each quarter.

The detailed analyses use a variety of generally accepted actuarial methods and techniques to produce a number of estimates of ultimate loss. CNA’s actuaries determine a point estimate of ultimate loss by reviewing the various estimates and assigning weight to each estimate given the characteristics of the reserve group being reviewed. The reserve estimate is the difference between the estimated ultimate loss and the losses paid to date. The difference between the estimated ultimate loss and the case incurred loss (paid loss plus case reserve) is IBNR. IBNR calculated as such includes a provision for development on known cases (supplemental development) as well as a provision for claims that have occurred but have not yet been reported (pure IBNR).

Most of CNA’s business can be characterized as long-tail. For long-tail business, it will generally be several years between the time the business is written and the time when all claims are settled. CNA’s long-tail exposures include commercial automobile liability, workers’ compensation, general liability, medical professional liability, other professional liability and management liability coverages, assumed reinsurance run-off and products liability. Short-tail exposures include property, commercial automobile physical damage, marine, surety and warranty. Property and casualty insurance operations contain both long-tail and short-tail exposures. Other non-core operations contain long-tail exposures.

Various methods are used to project ultimate loss for both long-tail and short-tail exposures including, but not limited to, the following:

52

Table of Contents

The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident or policy years with further expected changes in paid loss. Selection of the paid loss pattern may require consideration of several factors including the impact of inflation on claims costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, the impact of underwriting changes, the impact of large claim payments and other factors. Claim cost inflation itself may require evaluation of changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors. Because this method assumes that losses are paid at a consistent rate, changes in any of these factors can impact the results. Since the method does not rely on case reserves, it is not directly influenced by changes in the adequacy of case reserves.

For many reserve groups, paid loss data for recent periods may be too immature or erratic for accurate predictions. This situation often exists for long-tail exposures. In addition, changes in the factors described above may result in inconsistent payment patterns. Finally, estimating the paid loss pattern subsequent to the most mature point available in the data analyzed often involves considerable uncertainty for long-tail products such as workers’ compensation.

The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses. Since the method uses more data (case reserves in addition to paid losses) than the paid development method, the incurred development patterns may be less variable than paid patterns. However, selection of the incurred loss pattern typically requires analysis of all of the same factors described above. In addition, the inclusion of case reserves can lead to distortions if changes in case reserving practices have taken place, and the use of case incurred losses may not eliminate the issues associated with estimating the incurred loss pattern subsequent to the most mature point available.

The loss ratio method multiplies earned premiums by an expected loss ratio to produce ultimate loss estimates for each accident or policy year. This method may be useful for immature accident or policy periods or if loss development patterns are inconsistent, losses emerge very slowly, or there is relatively little loss history from which to estimate future losses. The selection of the expected loss ratio typically requires analysis of loss ratios from earlier accident or policy years or pricing studies and analysis of inflationary trends, frequency trends, rate changes, underwriting changes and other applicable factors.

The Bornhuetter-Ferguson method using paid loss is a combination of the paid development method and the loss ratio method. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method and typically requires analysis of the same factors described above. This method assumes that future losses will develop at the expected loss ratio level. The percent of paid loss to ultimate loss implied from the paid development method is used to determine what percentage of ultimate loss is yet to be paid. The use of the pattern from the paid development method typically requires consideration of the same factors listed in the description of the paid development method. The estimate of losses yet to be paid is added to current paid losses to estimate the ultimate loss for each year. For long-tail lines, this method will react very slowly if actual ultimate loss ratios are different from expectations due to changes not accounted for by the expected loss ratio calculation.

The Bornhuetter-Ferguson method using incurred loss is similar to the Bornhuetter-Ferguson method using paid loss except that it uses case incurred losses. The use of case incurred losses instead of paid losses can result in development patterns that are less variable than paid patterns. However, the inclusion of case reserves can lead to distortions if changes in case reserving have taken place, and the method typically requires analysis of the same factors that need to be reviewed for the loss ratio and incurred development methods.

The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident or policy year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for reserve groups where loss development patterns are inconsistent or too variable to be relied on exclusively. In addition, this method can more directly account for changes in coverage that impact the number and

53

Table of Contents

size of claims. However, this method can be difficult to apply to situations where very large claims or a substantial number of unusual claims result in volatile average claim sizes. Projecting the ultimate number of claims may require analysis of several factors including the rate at which policyholders report claims to CNA, the impact of judicial decisions, the impact of underwriting changes and other factors. Estimating the ultimate average loss may require analysis of the impact of large losses and claim cost trends based on changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors.

Stochastic modeling produces a range of possible outcomes based on varying assumptions related to the particular reserve group being modeled. For some reserve groups, CNA uses models which rely on historical development patterns at an aggregate level, while other reserve groups are modeled using individual claim variability assumptions supplied by the claims department. In either case, multiple simulations are run and the results are analyzed to produce a range of potential outcomes. The results will typically include a mean and percentiles of the possible reserve distribution which aid in the selection of a point estimate.

For many exposures, especially those that can be considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, CNA’s actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method. For most of CNA’s products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, CNA will not assign any weight to the paid and incurred development methods. CNA will use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods. For short-tail exposures, the paid and incurred development methods can often be relied on sooner primarily because CNA’s history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, CNA may also use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods for short-tail exposures.

For other more complex reserve groups where the above methods may not produce reliable indications, CNA uses additional methods tailored to the characteristics of the specific situation.

Periodic Reserve Reviews

The reserve analyses performed by CNA’s actuaries result in point estimates. Each quarter, the results of the detailed reserve reviews are summarized and discussed with CNA’s senior management to determine the best estimate of reserves. CNA’s senior management considers many factors in making this decision. The factors include, but are not limited to, the historical pattern and volatility of the actuarial indications, the sensitivity of the actuarial indications to changes in paid and incurred loss patterns, the consistency of claims handling processes, the consistency of case reserving practices, changes in CNA’s pricing and underwriting, pricing and underwriting trends in the insurance market and legal, judicial, social and economic trends.

CNA’s recorded reserves reflect its best estimate as of a particular point in time based upon known facts, consideration of the factors cited above and its judgment. The carried reserve may differ from the actuarial point estimate as the result of CNA’s consideration of the factors noted above as well as the potential volatility of the projections associated with the specific reserve group being analyzed and other factors affecting claims costs that may not be quantifiable through traditional actuarial analysis. This process results in management’s best estimate which is then recorded as the loss reserve.

Currently, CNA’s recorded reserves are modestly higher than the actuarial point estimate. For Commercial, Specialty and International, the difference between CNA’s reserves and the actuarial point estimate is primarily driven by uncertainty with respect to immature accident years, claim cost inflation, changes in claims handling, changes to the tort environment which may adversely impact claim costs and the effects from the economy. For CNA’s legacy A&EP liabilities, the difference between CNA’s reserves and the actuarial point estimate is primarily driven by the potential tail volatility of run-off exposures.

The key assumptions fundamental to the reserving process are often different for various reserve groups and accident or policy years. Some of these assumptions are explicit assumptions that are required of a particular method, but most of the assumptions are implicit and cannot be precisely quantified. An example of an explicit assumption is the pattern employed in the paid development method. However, the assumed pattern is itself based on several implicit assumptions such as the impact of inflation on medical costs and the rate at which claim professionals close claims. As a result, the effect on reserve estimates of a particular change in assumptions typically cannot be specifically quantified, and changes in these assumptions cannot be tracked over time.

CNA’s recorded reserves are management’s best estimate. In order to provide an indication of the variability associated with CNA’s net reserves, the following discussion provides a sensitivity analysis that shows the approximate estimated impact of variations in significant factors affecting CNA’s reserve estimates for particular types of business. These significant factors are the ones that CNA believes could most likely materially affect the reserves. This discussion covers the major types of business for which CNA believes a material deviation to its reserves is reasonably possible. There can be no assurance that actual experience will be consistent with the current assumptions or with the variation indicated by the discussion. In addition, there can be no assurance that other factors and assumptions will not have a material impact on CNA’s reserves.

The three areas for which CNA believes a significant deviation to its net reserves is reasonably possible are (i) professional liability, management liability and surety products; (ii) workers’ compensation and (iii) general liability.

Professional liability and management liability products and surety products include professional liability coverages provided to various professional firms, including architects, real estate agents, small and mid-sized accounting firms, law firms and other professional firms. They also include D&O, employment practices, fiduciary, fidelity and surety coverages, as well as insurance products serving the health care delivery system. The most significant factor affecting reserve estimates for these liability coverages is claim severity. Claim severity is driven by the cost of medical care, the cost of wage replacement, legal fees, judicial decisions, legislative changes and other factors. Underwriting and claim handling decisions such as the classes of business written and individual claim settlement decisions can also impact claim severity. If the estimated claim severity increases by 9%, CNA estimates that the net reserves would increase by approximately $500 million. If the estimated claim severity decreases by 3%, CNA estimates that net reserves would decrease by approximately $150 million. CNA’s net reserves for these products were approximately $5.4 billion as of December 31, 2015.

For workers’ compensation, since many years will pass from the time the business is written until all claim payments have been made, claim cost inflation on claim payments is the most significant factor affecting workers’ compensation reserve estimates. Workers’ compensation claim cost inflation is driven by the cost of medical care, the cost of wage replacement, expected claimant lifetimes, judicial decisions, legislative changes and other factors. If estimated workers’ compensation claim cost inflation increases by 100 basis points for the entire period over which claim payments will be made, CNA estimates that its net reserves would increase by approximately $400 million. If estimated workers’ compensation claim cost inflation decreases by 100 basis points for the entire period over which claim payments will be made, CNA estimates that its net reserves would decrease by approximately $350 million. Net reserves for workers’ compensation were approximately $4.3 billion as of December 31, 2015.

For general liability, the most significant factor affecting reserve estimates is claim severity. Claim severity is driven by changes in the cost of repairing or replacing property, the cost of medical care, the cost of wage replacement, judicial decisions, legislation and other factors. If the estimated claim severity for general liability increases by 6%, CNA estimates that its net reserves would increase by approximately $200 million. If the estimated claim severity for general liability decreases by 3%, CNA estimates that its net reserves would decrease by approximately $100 million. Net reserves for general liability were approximately $3.6 billion as of December 31, 2015.

Given the factors described above, it is not possible to quantify precisely the ultimate exposure represented by claims and related litigation. As a result, CNA regularly reviews the adequacy of its reserves and reassesses its reserve estimates as historical loss experience develops, additional claims are reported and settled and additional information becomes available in subsequent periods. In reviewing CNA’s reserve estimates, CNA makes adjustments in the period that the need for such adjustments is determined. These reviews have resulted in CNA’s

55

Table of Contents

identification of information and trends that have caused CNA to change its reserves in prior periods and could lead to the identification of a need for additional material increases or decreases in claim and claim adjustment expense reserves, which could materially affect our results of operations and equity and CNA’s business and insurer financial strength and corporate debt ratings positively or negatively. See the Ratings section of this MD&A for further information regarding CNA’s financial strength and corporate debt ratings.

The following table summarizes gross and net carried reserves for CNA’s property and casualty operations:

The following table summarizes the gross and net carried reserves for certain property and casualty business in run-off, including CNA Re and A&EP:

Life & Group Non-Core Policyholder Reserves

CNA maintains both claim and claim adjustment expense reserves as well as future policy benefit reserves for policyholder benefits for the Life & Group Non-Core business. Claim and claim expense reserves consist of estimated reserves for long term care policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported. In developing the claim and claim adjustment expense reserve estimates for CNA’s long term care policies, its actuaries perform a detailed claim experience study on an annual basis. The study reviews the sufficiency of existing reserves for policyholders currently on claim and includes an evaluation of expected benefit utilization and claim duration. CNA’s recorded claim and claim adjustment expense reserves reflect its best estimate after incorporating the results of the most recent study. In addition, claim and claim adjustment reserves are also maintained for structured settlement obligations that are not funded by annuities related to certain property and casualty claimants. Future policy benefit reserves represent the active life reserves related to CNA’s long term care policies and are the present value of expected future benefit payments and expenses less expected future premiums. The determination of these reserves is fundamental to its financial results and requires management to make estimates and assumptions about expected investment and policyholder experience over the life of the contract. Since many of these contracts may be in force for several decades, these assumptions are subject to significant estimation risk.

While the structured settlement obligations arise under short duration contracts, long duration contract principles and actuarial methods are used to determine management’s best estimate of the required claim and claim adjustment reserve.

56

Table of Contents

Under GAAP, reserves for long term care future policy benefits and the unfunded structured settlement annuity claim and claim adjustment expense reserves were first established based on CNA’s actuarial best estimate assumptions at the date the contract was issued plus a margin for adverse deviation. Actuarial assumptions include estimates of morbidity, persistency, discount rates and expenses over the life of the contracts. These assumptions are locked in throughout the life of the contract unless a premium deficiency develops. The impact of differences between the actuarial assumptions and actual experience is reflected in results of operations each period.

Long term care policies provide benefits for nursing home, assisted living and home health care subject to various daily and lifetime caps. Policyholders must continue to make periodic premium payments to keep the policy in force. Generally CNA has the ability to increase policy premiums, subject to state regulatory approval.

The actuarial assumptions that management believes are subject to the most variability are morbidity, persistency and discount rate. Persistency can be affected by policy lapses and death. Discount rate is influenced by the investment yield on assets supporting long term care reserves which is subject to interest rate and market volatility. There is limited historical company and industry data available to CNA for long term care morbidity and mortality, as only a portion of the policies written to date are in claims paying status. As a result of this variability, CNA’s long term care reserves may be subject to material increases if actual experience develops adversely to its expectations.

Annually, management assesses the adequacy of its GAAP long term care future policy benefit reserves as well as the claim and claim adjustment expense reserves for unfunded structured settlement obligations by performing a gross premium valuation (“GPV”) to determine if there is a premium deficiency. Under the GPV, management estimates required reserves using best estimate assumptions, including anticipated future premium rate increases, as of the date of the assessment without provisions for adverse deviation. The GPV reserves are then compared to the recorded reserves. If the GPV reserves are greater than the existing net GAAP reserves (i.e. reserves net of any deferred acquisition costs asset), the existing net GAAP reserves are unlocked and are increased to the greater amount. Any such increase is reflected in CNA’s results of operations in the period in which the need for such adjustment is determined, and could materially adversely affect our results of operations and equity and CNA’s business and insurer financial strength and corporate debt ratings.

Prior to December 31, 2015, the active life reserves for long term care were based on actuarial assumptions established at policy issuance. The December 31, 2014 GPV indicated the carried reserves included a margin of approximately $100 million. The December 31, 2015 GPV indicated a premium deficiency of $296 million. A summary of the changes in the GPV results is presented in the table below:

The premium deficiency was primarily driven by changes in morbidity assumptions in particular by higher claim incidence, reflective of trends observed in CNA’s emerging experience. There are a variety of factors that impact claim incidence rates, including, but not limited to, policyholder behavior, socioeconomic factors, changes in health trends and advances in medical care. The premium deficiency was also adversely affected by changes in persistency assumptions, primarily from lower projected active life mortality rates. Adverse changes from morbidity and persistency were somewhat offset by increases in planned rate increase actions and changes in discount rate assumptions. The increase in planned rate actions was primarily due to updated assumptions on the approval rate and timing of future premium rate increases in CNA’s group block. Changes in discount rate assumptions were

57

Table of Contents

primarily due to changes in future interest rate assumptions, contemplating both near-term market indications and long-term normative assumptions. Changes in expenses and other assumptions had a small adverse impact on the premium deficiency.

The indicated premium deficiency necessitated a charge to income that was effected by the write off of the entire long term care deferred acquisition cost asset of $289 million and an increase to active life reserves of $7 million. As a result, the long term care active life reserves carried as of December 31, 2015 represent management’s best estimate assumptions at that date with no margin for adverse deviation. Since there is no margin in the carried reserves, CNA may have to unlock its reserve assumptions in the future. Factors that could affect the need to unlock reserve assumptions include the significance and persistence of variances between actual experience and the expected results contemplated in the best estimate reserves as well as changes in CNA’s outlook of the future.

In addition to the premium deficiency, CNA’s annual experience study of claim reserves indicated a deficiency of $9 million. The deficiency was primarily related to updating claim frequency assumptions on incurred but not reported claims, offset by favorable severity on existing claims. The total impact of the premium deficiency and claim reserve deficiency was $177 million (after tax and noncontrolling interests).

The table below summarizes the estimated pretax impact on CNA’s results of operations from various hypothetical revisions to its assumptions. CNA has assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group and would occur absent any changes, mitigating or otherwise, in the other assumptions. Although such hypothetical revisions are not currently required or anticipated, CNA believes they could occur based on past variances in experience and its expectations of the ranges of future experience that could reasonably occur. The hypothetical revisions have been updated from the disclosures in prior periods to be reflective of CNA’s updated best estimate assumptions as of December 31, 2015 in support of its active life reserves. As a result, in some cases the scenarios described below are not directly comparable to prior periods. Persistency now reflects active life mortality and lapse whereas prior periods reflected total lives. Discount rates now reflect future interest rates only whereas prior periods reflected future interest rates and changes in CNA’s existing investment portfolio yield. The hypothetical scenarios for morbidity and premium rate actions are comparable to prior periods.

Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized above.
