Columbia Banking System, Inc.


1.	Basis of Presentation, Significant Accounting Policies and Reclassifications

Basis of Presentation

The interim unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. The Consolidated Financial Statements include the accounts of Columbia Banking System, Inc. (“we”, “our”, “Columbia” or the “Company”) and its subsidiaries, including its wholly owned banking subsidiary Columbia State Bank (“Columbia Bank” or the “Bank”) and Columbia Trust Company (“Columbia Trust”). All intercompany transactions and accounts have been eliminated in consolidation. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. The results of operations for the six months ended June 30, 2019 are not necessarily indicative of results to be anticipated for the year ending December 31, 2019. The accompanying interim unaudited Consolidated Financial Statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2018 Annual Report on Form 10-K.

Significant Accounting Policies

The significant accounting policies used in preparation of our Consolidated Financial Statements are disclosed in our 2018 Annual Report on Form 10-K. There have not been any changes in our significant accounting policies compared to those contained in our 2018 Form 10-K disclosure for the year ended December 31, 2018.

Reclassifications

Certain amounts reported in prior periods have been reclassified in the Consolidated Financial Statements to conform to the current presentation. The reclassifications have no effect on net income or stockholders’ equity as previously reported.


2.	Accounting Pronouncements Recently Adopted or Issued

Accounting Standards Adopted in 2019

In February 2016, the FASB issued ASU 2016-02, Leases. The amendments included in this ASU create a new accounting model for both lessees and lessors. The new guidance requires lessees to recognize lease liabilities, initially measured as the present value of future lease payments, and corresponding right-of-use assets for all leases with lease terms greater than 12 months. The new lease model differs from the old lease accounting model, as the old model does not require such lease liabilities and corresponding right-of-use assets to be recorded for operating leases. The amendments in ASU 2016-02 must be adopted using the modified retrospective approach and will be effective for the first interim or annual period beginning after December 15, 2018. The FASB subsequently issued ASU 2018-11, which allows for an additional (optional) transition method. The Company adopted the new standard effective January 1, 2019 utilizing the transition method allowed under ASU 2018-11 and did not restate comparative periods. The Company elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classifications and our assessment on whether a contract is or contains a lease. We also elected to keep leases with an initial term of 12 months or less off the balance sheet. The adoption of the new standard resulted in an increase in other assets and an increase in other liabilities of $49.2 million and $48.2 million, respectively. The Company recognized a cumulative effect adjustment of $782 thousand to increase the beginning balance of retained earnings related to previous deferred gains on sale-leaseback transactions.

Recently Issued Accounting Standards, Not Yet Adopted

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments in this ASU clarify certain aspects of accounting for credit losses, hedging activities, and financial instruments (addressed by ASUs 2016-01, 2016-13, and 2017-12). Many of the amendments reflect decisions reached at FASB meetings or meetings of the Board’s credit losses transition resource group. Topics covered in this ASU include: accrued interest, transfers between classifications or categories for loans and debt securities, recoveries, reinsurance recoverables, projections of interest rate environments for variable-rate financial instruments, costs to sell when foreclosure is probable, consideration of expected prepayments when determining the effective interest rate, vintage disclosures, extension and renewal options, etc. The amendments in ASU 2019-04 are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is assessing the impact that this guidance will have on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, including reasonably certain renewal periods. The amendments in ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is assessing the impact that this guidance will have on its Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The amendments included in this ASU require an entity to reflect its current estimate of all expected credit losses for assets held at an amortized cost basis. For available for sale debt securities, credit losses will be measured in a manner similar to current GAAP, however, this ASU will require that credit losses be presented as an allowance rather than as a write-down. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and are required to be adopted through a modified retrospective approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is effective.

Although the Company is in the final stages of determining an initial estimate, it currently cannot reasonably estimate the impact that the adoption of ASU 2016-13 will have on its Consolidated Financial Statements. That assessment is based upon the fact that, unlike the incurred loss models in existing GAAP, the CECL model in ASU 2016-13 does not specify a threshold for the recognition of an impairment allowance. Rather, the Company will recognize an impairment allowance equal to its estimate of lifetime expected credit losses, adjusted for prepayments, for in-scope financial instruments as of the end of the reporting period. Accordingly, the impairment allowance measured under the CECL model could increase significantly from the impairment allowance measured under the Company’s existing incurred loss model. The Company has engaged a third-party vendor to assist in the CECL calculation and has developed an internal governance framework to oversee the CECL implementation. Other significant CECL implementation matters being addressed by the Company include selecting loss estimation methodologies, identifying, sourcing and storing data, addressing data gaps, defining a reasonable and supportable forecast period, selecting historical loss information, assessing the impact to internal controls over financial reporting, and capital planning.

At June 30, 2019, there were 230 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligations securities in an unrealized loss position, of which 228 were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2019.

At June 30, 2019, there were 134 state and municipal government securities in an unrealized loss position, of which 126 were in a continuous loss position for 12 months or more. The unrealized losses on state and municipal securities were caused by interest rate changes or widening of market spreads subsequent to the purchase of the individual securities. Management monitors published credit ratings of these securities for adverse changes. As of June 30, 2019, none of the rated obligations of state and local government entities held by the Company had a below investment grade credit rating. Because the credit quality of these securities are investment grade and the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2019.

At June 30, 2019, there were 13 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, of which 12 were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not currently intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2019.

Table of Contents

At June 30, 2019, there was one U.S. government security in an unrealized loss position, which was also in a continuous loss position for more than 12 months. The decline in fair value is attributable to changes in interest rates relative to where this investment falls within the yield curve and its individual characteristics. Because the Company does not currently intend to sell this security nor does the Company consider it more likely than not that it will be required to sell this security before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider this investment to be other-than-temporarily impaired at June 30, 2019.

The Company’s loans classified as TDR are loans that have been modified or the borrower has been granted special concessions due to financial difficulties that, if not for the challenges of the borrower, the Company would not otherwise consider. The TDR modifications or concessions are made to increase the likelihood that these borrowers with financial difficulties will be able to satisfy their debt obligations as amended. The concessions granted in the restructurings, summarized in the table above, largely consisted of maturity extensions, interest rate modifications or a combination of both. In limited circumstances, a reduction in the principal balance of the loan could also be made as a concession. Credit losses for loans classified as TDR are measured on the same basis as impaired loans. For impaired loans, an allowance is established when the collateral value less selling costs (or discounted cash flows or observable market price) of the impaired loan is lower than the recorded investment of that loan.

The Company had commitments to lend $464 thousand of additional funds on loans classified as TDR as of June 30, 2019. The Company had $2.1 million of such commitments at December 31, 2018. The Company did not have any loans modified as TDR that defaulted within 12 months of being modified as TDR during the three months ended June 30, 2019. The Company did have one $26 thousand consumer loan that defaulted within 12 months of being modified as a TDR during the six months ended June 30, 2019. The defaulted TDR loan is collateralized and was included with the loans individually measured for specific impairment. The Company did not experience any similar defaults during the three and six months ended June 30, 2018.

PCI Loans

PCI loans are accounted for under ASC 310-30 and initially measured at fair value based on expected future cash flows over the life of the loans. Loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.

Contractual cash flows are calculated based upon the loan pool terms after applying a prepayment factor. Calculation of the applied prepayment factor for contractual cash flows is the same as described below for expected cash flows.

Table of Contents

Inputs to the determination of expected cash flows include cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix, which utilizes probability values of a loan pool transitioning into a particular delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) given its delinquency state at the remeasurement date. Loss severity factors are based upon either actual charge-off data within the loan pools or industry averages, and recovery lags are based upon the collateral within the loan pools.

The excess of cash flows, expected to be collected over the initial fair value of PCI loans, is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired loans using the effective yield method. Other adjustments to the accretable yield include changes in the estimated remaining life of the acquired loans, changes in expected cash flows and changes of indices for acquired loans with variable interest rates.

Risk Elements

The extension of credit in the form of loans or other credit products to individuals and businesses is one of our principal business activities. Our policies and applicable laws and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry and type of borrower and by limiting the aggregation of debt to a single borrower.

Risk ratings are reviewed and updated whenever appropriate, with more periodic reviews as the risk and dollar value of loss on the loan increases. In the event full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan.

Pass rated loans are generally considered to have sufficient sources of repayment in order to repay the loan in full in accordance with all terms and conditions. Special Mention rated loans have potential weaknesses that, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans with a risk rating of Substandard or worse are reviewed to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating or accrual status may be adjusted accordingly. Loans risk rated as Substandard reflect loans where a loss is possible if loan weaknesses are not corrected. Doubtful rated loans have a high probability of loss; however, the amount of loss has not yet been determined. Loss rated loans are considered uncollectable and when identified, are charged off.

7.	Goodwill and Other Intangible Assets

In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value.

The CDI is evaluated for impairment if events and circumstances indicate a possible impairment. The CDI is amortized on an accelerated basis over an estimated life of 10 years.

The following table sets forth activity for goodwill and other intangible assets for the periods indicated:

8.	Leases

The Company’s lease commitments consist primarily of leased locations under various non-cancellable operating leases that expire between 2019 and 2043. The majority of the leases contain renewal options and provisions for increases in rental rates based on an agreed upon index or predetermined escalation schedule.

The following table shows the details of the Company’s operating lease right-of-use asset and the associated lease liability for the period indicated:

At June 30, 2019, the Company’s operating leases have a weighted-average remaining lease term of 7.7 years and a weighted average discount rate of 3.2%. Cash paid for amounts included in the measurement of operating lease liabilities was $5.6 million for the six months ended June 30, 2019. Right-of-use assets obtained in exchange for new operating lease liabilities during the six months ended June 30, 2019 was $3.6 million.

9.	Revolving Line of Credit

During the second quarter of 2019, the Company entered into a $30.0 million short-term credit facility with an unaffiliated bank that matures in May 2020. This facility has a variable interest rate and provides the Company additional liquidity, if needed, for various corporate activities including the repurchase of Columbia Banking System, Inc. common stock. As of June 30, 2019 and December 31, 2018, there was no outstanding balance. The credit agreement requires the Company to comply with certain covenants including those related to asset quality and capital levels. The Company was in compliance with all covenants associated with this facility at June 30, 2019.


10.	Derivatives, Hedging Activities and Balance Sheet Offsetting

The Company is exposed to certain risks arising from both its business and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loan portfolio.

The Company’s objectives in using interest rate derivatives are to add stability to interest income and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate collars as part of its interest rate risk management strategy. Interest rate collars designated as cash flow hedges involve the payments of variable-rate amounts if interest rates rise above the cap strike rate on the contract and receipts of variable-rate amounts if interest rates fall below the floor strike rate on the contract. These derivative contracts are used to hedge the variable cash flows associated with existing variable-rate assets.

Table of Contents

With respect to derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest income in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest income as interest payments are received on the Company’s variable-rate assets. During the next 12 months, the Company estimates that there will be $2.1 million reclassified as an increase to interest income.

In addition, the Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third-party in order to offset its exposure on the variable and fixed components of the customer agreement. As the interest rate swap agreements with the customers and third parties are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the instruments are marked to market in earnings. The notional amount of open interest rate swap agreements at June 30, 2019 and December 31, 2018 was $373.0 million and $366.7 million, respectively. During the three and six months ended June 30, 2019, there was $2 thousand mark-to-market loss recorded to “Other” noninterest expense. During the three and six months ended June 30, 2018, mark-to-market gains of $2 thousand and $8 thousand, respectively, were recorded to “Other” noninterest expense.

Table of Contents

The Company is party to interest rate swap contracts, interest rate collar and repurchase agreements that are subject to enforceable master netting arrangements or similar agreements. Under these agreements, the Company may have the right to net settle multiple contracts with the same counterparty. The following tables show the gross interest rate swap contracts, collar agreements and repurchase agreements in the Consolidated Balance Sheets and the respective collateral received or pledged in the form of cash or other financial instruments. The collateral amounts in these tables are limited to the outstanding balances of the related asset or liability. Therefore, instances of overcollateralization are not shown.

The Company’s agreements with each of its derivative counterparties provide that if the Company defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations.

The following table presents the class of collateral pledged for repurchase agreements as well as the remaining contractual maturity of the repurchase agreements:



	Remaining contractual maturity of the agreements
	Overnight and continuous		Up to 30 days		30 - 90 days		Greater than 90 days		Total

Gross amount of recognized liabilities for repurchase agreements									50,226
Amounts related to agreements not included in offsetting disclosure									$	—

The collateral utilized for the Company’s repurchase agreements is subject to market fluctuations as well as prepayments of principal. The Company monitors the risk of the fair value of its pledged collateral falling below acceptable amounts based on the type of the underlying repurchase agreement. The pledged collateral related to the Company’s $50.2 million sweep repurchase agreements, which mature on an overnight basis, is monitored on a daily basis as the underlying sweep accounts can have frequent transaction activity and the amount of pledged collateral is adjusted as necessary.

11.	Commitments and Contingent Liabilities

Financial Instruments with Off-Balance Sheet Risk: In the normal course of business, the Company makes loan commitments (typically unfunded loans and unused lines of credit) and issues standby letters of credit to accommodate the financial needs of its customers. At June 30, 2019 and December 31, 2018, the Company’s loan commitments amounted to $2.59 billion and $2.62 billion, respectively.

Standby letters of credit commit the Company to make payments on behalf of customers under specified conditions. Historically, no significant losses have been incurred by the Company under standby letters of credit. Both arrangements have credit risk essentially the same as that involved in extending loans to customers and are subject to the Company’s normal credit policies, including collateral requirements, where appropriate. Standby letters of credit were $35.1 million and $28.3 million at June 30, 2019 and December 31, 2018, respectively. In addition, there were $286 thousand commitments under commercial letters of credit used to facilitate customers’ trade transactions and other off-balance sheet liabilities at June 30, 2019 and none at December 31, 2018, respectively.

Legal Proceedings: The Company and its subsidiaries are from time to time defendants in and are threatened with various legal proceedings arising from their regular business activities. Management, after consulting with legal counsel, is of the opinion that the ultimate liability, if any, resulting from these pending or threatened actions and proceedings will not have a material effect on the financial statements of the Company.


12.	Shareholders’ Equity

Dividends:

The following table summarizes year-to-date dividend activity as of June 30, 2019:



Declared	Regular Cash Dividends Per Common Share		Special Cash Dividends Per Common Share		Record Date	Paid Date
January 24, 2019	$	0.28	$	0.14	February 6, 2019	February 20, 2019
April 25, 2019	$	0.28	$	0.14	May 8, 2019	May 22, 2019

Subsequent to quarter end, on July 25, 2019, the Company declared a regular quarterly cash dividend of $0.28 per common share payable on August 21, 2019 to shareholders of record at the close of business on August 7, 2019.

The payment of cash dividends is subject to federal regulatory requirements for capital levels and other restrictions. In addition, the cash dividends paid by Columbia Bank to the Company are subject to both federal and state regulatory requirements.

Share Repurchase Program:

For the three and six months ended June 30, 2019, the Company repurchased 624,158 shares of common stock at an average price of $35.03 per share. As of June 30, 2019, there are 2,275,842 remaining shares authorized to be repurchased under the current Board approved share repurchase program.

14.	Fair Value Accounting and Measurement

The Fair Value Measurements and Disclosures topic of the FASB ASC defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value. We hold fixed and variable rate interest-bearing securities, investments in marketable equity securities and certain other financial instruments, which are carried at fair value. Fair value is determined based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available.

The valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 – Quoted prices for identical instruments in active markets that are accessible at the measurement date.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable.

Fair values are determined as follows:

Securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury Notes and equity securities, which are considered a Level 1 input method.

Interest rate contracts and the interest rate collar are valued in models, which use as their basis, readily observable market parameters and are classified within Level 2 of the valuation hierarchy.

Table of Contents

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at June 30, 2019 and December 31, 2018 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

Nonrecurring Measurements

Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment. The following method was used to estimate the fair value of impaired loans:

Impaired loans—A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or the fair market value of the collateral less estimated costs to sell if the loan is a collateral-dependent loan. The impairment evaluations are performed in conjunction with the allowance process on a quarterly basis by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD, which also reports to the Chief Credit Officer, is responsible for obtaining appraisals from third-parties or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy and reasonableness.

The following tables set forth information related to the Company’s assets that were measured using fair value estimates on a nonrecurring basis during the current and prior year quarterly periods:

15.	Earnings Per Common Share

The Company applies the two-class method of computing basic and diluted EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company issues restricted shares under share-based compensation plans which qualify as participating securities.

The following table sets forth the computation of basic and diluted EPS for the three and six months ended June 30, 2019 and 2018:

16.	Revenue from Contracts with Customers

Revenue in the scope of Topic 606, Revenue from Contracts with Customers is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The vast majority of the Company’s revenue is specifically outside the scope of Topic 606. For in-scope revenue, the following is a description of principal activities, separated by the timing of revenue recognition from which the Company generates its revenue from contracts with customers.

Revenue earned at a point in time - Examples of revenue earned at a point in time are ATM transaction fees, wire transfer fees, overdraft fees, interchange fees and foreign exchange transaction fees. Revenue is primarily based on the number and type of transactions and is generally derived from transactional information accumulated by our systems and is recognized immediately as the transactions occur or upon providing the service to complete the customer’s transaction. The Company is the principal in each of these contracts, with the exception of interchange fees, in which case we are acting as the agent and record revenue net of expenses paid to the principal.

Revenue earned over time - The Company earns revenue from contracts with customers in a variety of ways where the revenue is earned over a period of time - generally monthly. Examples of this type of revenue are deposit account maintenance fees, investment advisory fees, merchant revenue and safe deposit box fees. Revenue is generally derived from transactional information accumulated by our systems or those of third-parties and is recognized as the related transactions occur or services are rendered to the customer.

Table of Contents

The Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are typically satisfied as services are rendered and our contracts generally do not include multiple performance obligations. As a result, there are no contract balances as payments and services are rendered simultaneously. Payment is generally collected at the time services are rendered, monthly or quarterly. Unsatisfied performance obligations at the report date are not material to our consolidated financial statements.

In certain cases, other parties are involved with providing products and services to our customers. If the Company is principal in the transaction (providing goods or services itself), revenues are reported based on the gross consideration received from the customer and any related expenses are reported gross in noninterest expense. If the Company is an agent in the transaction (arranging for another party to provide goods or services), the Company reports its net fee or commission retained as revenue.

Rebates, waivers and reversals are recorded as a reduction of the transaction price either when the revenue is recognized by the Company or at the time the rebate, waiver or reversal is earned by the customer.

Practical expedients

The Company applies the practical expedient in paragraph 606-10-32-18 and does not adjust the consideration from customers for the effects of a significant financing component if at contract inception the period between when the entity transfers the goods or services and when the customer pays for that good or service will be one year or less.

The Company pays sales commissions to its employees in accordance with certain incentive plans and in connection with obtaining certain contracts with customers. The Company applies the practical expedient in paragraph 340-40-25-4 and expenses such sales commissions when incurred if the amortization period of the asset the Company otherwise would have recognized is one year or less. Sales commissions are included in compensation and employee benefits expense.

For the Company’s contracts that have an original expected duration of one year or less, the Company uses the practical expedient in paragraph 606-10-50-14 and has not disclosed the amount of the transaction price allocated to unsatisfied performance obligations as of the end of each reporting period or when the Company expects to recognize this revenue.

Disaggregation of revenue

The following table shows the disaggregation of revenue from contracts with customers for the three and six month periods ended June 30, 2019 and 2018:

CRITICAL ACCOUNTING POLICIES

Management has identified the accounting policies related to the ALLL, business combinations and the valuation and recoverability of goodwill as critical to an understanding of our financial statements. These policies and related estimates are discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” under the headings “Allowance for Loan and Lease Losses,” “Business Combinations” and “Valuation and Recoverability of Goodwill” in our 2018 Annual Report on Form 10-K. There have not been any material changes in our critical accounting policies as compared to those disclosed in our 2018 Annual Report on Form 10-K.

RESULTS OF OPERATIONS

Our results of operations are dependent to a large degree on our net interest income. We also generate noninterest income from our broad range of products and services including treasury management, wealth management and debit and credit cards. Our operating expenses consist primarily of compensation and employee benefits, occupancy, data processing and legal and professional fees. Like most financial institutions, our interest income and cost of funds are affected significantly by general economic conditions, particularly changes in market interest rates, and by government policies and actions of regulatory authorities.

Earnings Summary

Comparison of current quarter to prior year period

The Company reported net income for the second quarter of $51.7 million or $0.71 per diluted common share, compared to $41.7 million or $0.57 per diluted common share for the second quarter of 2018. Net interest income for the three months ended June 30, 2019 was $125.1 million, an increase of $8.4 million from the prior year period. The increase was primarily driven by $4.9 million of interest recoveries on nonaccrual loans received in the second quarter of 2019 related to two lending relationships. In addition, interest income on loans and taxable securities increased due to both higher average balances and higher rates.

The provision for loan and lease losses for the second quarter of 2019 was $218 thousand compared to $4.0 million during the second quarter of 2018. The lower provision expense recorded in the second quarter of 2019 compared to one year ago was primarily due to an improvement in the credit quality of our loan portfolio.

Noninterest income for the current quarter was $25.6 million, an increase of $2.0 million from the prior year period. The increase was primarily due to $3.0 million in BOLI benefits and a $667 thousand gain on disposal of loans during the second quarter of 2019, partially offset by lower card revenue.

Total noninterest expense for the quarter ended June 30, 2019 was $86.7 million, an increase of $2.1 million from the prior year period. After removing acquisition-related expenses of $2.8 million from the second quarter of 2018, year over year noninterest expense increased $4.9 million, or 6%. This increase was primarily driven by higher compensation and employee benefits and legal and professional expenses, partially offset by a decrease in OREO expenses.

Table of Contents

Comparison of current year-to-date to prior year period

Net interest income for the six months ended June 30, 2019 was $246.1 million, an increase of $14.0 million from the prior year period. The increase was a result of the previously noted $4.9 million of loan interest recoveries and higher rates on the loan portfolio, partially offset by higher rates on deposits and an increase in FHLB advances.

The provision for loan and lease losses for the six months ended June 30, 2019 was $1.6 million compared to a provision of $9.8 million for the first six months of 2018. The decrease in the provision for the first half of 2019 compared to the same period in 2018 was due to an improvement in the credit quality of our loan portfolio.

Noninterest income for the six months ended June 30, 2019 was $47.3 million, an increase of $509.0 thousand from the prior year period. The increase was primarily due to the previously noted BOLI benefit, gain on sale of disposal of loans and the net gain on sale of securities during the six months ended June 30, 2019, partially offset by the previously noted lower card revenue as a result of the interchange fee cap.

__________

(1)

Nonaccrual loans have been included in the tables as loans carrying a zero yield. Amortized net deferred loan fees and net unearned discounts on acquired loans were included in the interest income calculations. The amortization of net deferred loan fees was $2.1 million for both the three months ended June 30, 2019 and 2018. The incremental accretion income on acquired loans was $2.7 million and $3.0 million for the three months ended June 30, 2019 and 2018, respectively.

(2)

Tax-exempt income is calculated on a tax equivalent basis. The tax equivalent yield adjustment to interest earned on loans was $1.4 million and $1.1 million for the three months ended June 30, 2019 and 2018, respectively. The tax equivalent yield adjustment to interest earned on tax exempt securities was $721 thousand and $814 thousand for the three months ended June 30, 2019 and 2018, respectively.


(3)	Beginning January 2019, average rates were calculated using the actual number of days on an actual/actual basis. This change was done to provide more meaningful trend information for our NIM regardless of the number of days in the period. Prior periods, which were previously reported on a 30/360 basis, have been restated to conform to the current basis.

(1)

Nonaccrual loans have been included in the table as loans carrying a zero yield. Amortized net deferred loan fees and net unearned discounts on acquired loans were included in the interest income calculations. The amortization of net deferred loan fees was $4.3 million for both the six months ended June 30, 2019 and 2018. The incremental accretion income on acquired loans was $4.7 million and $6.7 million for the six months ended June 30, 2019 and 2018, respectively.


(2)	Tax-exempt income is calculated on a tax equivalent basis. The tax equivalent yield adjustment to interest earned on loans was $2.7 million and $2.2 million for the six months ended June 30, 2019 and 2018, respectively. The tax equivalent yield adjustment to interest earned on tax exempt securities was $1.5 million and $1.6 million for the six months ended June 30, 2019 and 2018, respectively.


(3)	Beginning January 2019, average rates were calculated using the actual number of days to be on an actual/actual basis. This change was done to provide more meaningful trend information for our net interest margin regardless of the number of days in the period. Prior periods, which were previously reported on a 30/360 basis, have been restated to conform to the current basis.

The following table sets forth the total dollar amount of change in interest income and interest expense. The changes have been segregated for each major category of interest-earning assets and interest-bearing liabilities into amounts attributable to changes in volume and changes in rates. Changes attributable to the combined effect of volume and interest rates have been allocated proportionately to the changes due to volume and the changes due to interest rates:

(1) Beginning January 2019, net interest margin (tax equivalent) and operating net interest margin (tax equivalent) were calculated using the actual number of days and on an actual/actual basis. This change was done to provide more meaningful trend information for our NIM regardless of the number of days in the period. Prior periods, which were previously reported on a 30/360 basis, have been restated to conform to the current basis.

(2) Operating net interest margin (tax equivalent) is a non-GAAP measurement. See Non-GAAP measures section of Item 2, Management’s Discussion and Analysis.

Comparison of current quarter to prior year period

Net interest income for the second quarter of 2019 was $125.1 million, up from $116.7 million for the same quarter in 2018. The increase was primarily due to $4.9 million of loan interest recoveries on nonaccrual loans received in the second quarter of 2019 related to two lending relationships. In addition, interest income on loans and taxable securities increased due to both higher average balances and higher rates. The Company’s net interest margin (tax equivalent) increased to 4.40% in the second quarter of 2019, from 4.30% for the prior year period. This increase was due to the previously noted loan interest recoveries and higher rates on the loan portfolio, partially offset by higher rates on our deposits and borrowings. The Company’s operating net interest margin (tax equivalent) (see footnote 2 in prior table) increased to 4.38%, or 10 basis points, from 4.28% during the second quarter of 2018. The increase was due to the items previously noted for the increase in the net interest margin.

Comparison of current year-to-date to prior year period

Net interest income for the six months ended June 30, 2019 was $246.1 million, an increase of 6% from $232.2 million for the prior year period. The increase in net interest income was primarily due to the previously noted $4.9 million of loan interest recoveries. Interest income on loans and taxable securities increased due to both higher average balances and higher rates. The Company’s net interest margin (tax equivalent) increased to 4.36% for the first six months of 2019, from 4.29% for the prior year period. The increase in the Company’s net interest margin (tax equivalent) was driven by the previously noted loan interest recoveries and higher rates on the loan portfolio, which were partially offset by higher rates on our deposits and borrowings. The Company’s operating net interest margin (tax equivalent) for the six months ended June 30, 2019 increased to 4.36% from 4.26% due to the same reasons for the increase in the net interest margin.

Provision for Loan and Lease Losses

Comparison of current quarter to prior year period

During the second quarter of 2019, the Company recorded a $218 thousand net provision for loan losses compared to a $4.0 million net provision during the second quarter of 2018. The decrease in the provision for loan losses was due to an improvement in the credit quality of the loan portfolio. In addition, we recorded a large charge-off in our agricultural loan portfolio during the second quarter of 2018. The net provision for loan and lease losses recorded during the current quarter included management’s ongoing assessment of the credit quality of the Company’s loan portfolio. Factors affecting the provision include net charge-offs, credit quality migration, and size and composition of the loan portfolio and changes in the economic environment during the second quarter of 2019. The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 5 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Table of Contents

Comparison of current year-to-date to prior year period

The provision for loan and lease losses for the six months ended June 30, 2019 was $1.6 million compared to $9.8 million during the same period in 2018. The decrease in the provision for the first half of 2019 was primarily due to the improved credit quality of our loan portfolio. We also recorded a large charge-off in our agricultural loan portfolio during the six months ended June 30, 2018, as noted above. The amount of provision was calculated in accordance with the Company’s methodology for determining ALLL, discussed in Note 5 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Comparison of current quarter to prior year period

Noninterest income was $25.6 million for the second quarter of 2019, compared to $23.7 million for the same period in 2018. The increase was due to $3.0 million in BOLI benefits and a $667 thousand gain on disposal of loans included in other noninterest income. These increases were partially offset by lower card revenue during the second quarter of 2019 because, as of July 1, 2018, we became subject to the interchange fee cap imposed under the Dodd-Frank Act.

Comparison of current year-to-date to prior year period

For the six months ended June 30, 2019, noninterest income was $47.3 million compared to $46.8 million for the same period in 2018, an increase of $509 thousand. The increase was due to the previously noted BOLI benefits and gain on disposal of loans as well as the $2.1 million net gain on sale of securities, partially offset by lower card revenue as a result of the interchange fee cap, as previously noted.

(1) There were no acquisition-related expenses recorded during the three or six months ended June 30, 2019. All of the acquisition-related expenses in 2018 were related to the 2017 acquisition of Pacific Continental.

Comparison of current quarter to prior year period

Total noninterest expense for the second quarter of 2019 was $86.7 million, an increase of $2.1 million from $84.6 million for the prior year period. After removing the acquisition-related expenses of $2.8 million from the first quarter of 2018, year over year noninterest expense increased $4.9 million, or 6%. This increase was primarily driven by higher compensation and employee benefits and legal and professional expenses, partially offset by a decrease in OREO expenses. Salary expense increased as a result of the rise in the number of employees compared to June 30, 2018. Legal and professional fees were $2.6 million higher in the current period primarily due to expenses related to the digital corporate initiative. These increases in expenses were partially offset by a net benefit on OREO in the second quarter of 2019 compared to a net cost of $758 thousand in the second quarter of 2018.

Table of Contents

Comparison of current year-to-date to prior year period

For the six months ended June 30, 2019, noninterest expense was $171.4 million, an increase of $798 thousand from $170.6 million a year earlier. After removing the acquisition-related expenses of $7.1 million from the first six months of 2018, year over year noninterest expense increased $7.9 million, or 5%. The increase from the prior year period was driven by higher compensation and employee benefits expense and higher legal and professional fees, partially offset by decreases in OREO expenses. Salary expense increased $3.8 million, incentive plan expense increased $1.3 million and benefits expense increased $838 thousand compared to the first half of 2018. Professional fees increased $3.3 million due primarily to the digital corporate initiative. These increases in noninterest expense were partially offset by the $592 thousand current year net benefit of OREO expenses resulting from a gain on the sale of OREO, mentioned previously, compared to net OREO operating expenses of $759 thousand during the six months ended June 30, 2019.

Income Taxes

We recorded an income tax provision of $12.1 million for the second quarter of 2019, compared to a provision of $10.0 million for the same period in 2018, with effective tax rates of 19% for both the second quarter of 2019 and 2018. For the six months ended June 30, 2019 and 2018, we recorded income tax provisions of $22.9 million and $16.8 million, respectively, with effective tax rates of 19% for the current year and 17% for the prior year period. Our effective tax rate remains lower than the statutory tax rate due to tax-exempt income from municipal securities, BOLI and certain loan receivables. For additional information, please refer to the Company’s annual report on Form 10-K for the year ended December 31, 2018.

FINANCIAL CONDITION

Total assets were $13.09 billion at June 30, 2019, a decrease of $4.3 million from December 31, 2018. Cash and cash equivalents decreased $18.9 million. Loans increased $255.5 million during the current year, which was primarily the result of increased loan production, partially offset by principal pay downs. Debt securities available for sale were $2.86 billion at June 30, 2019, a decrease of $303.0 million from December 31, 2018 as earning assets rotated into loans. Total liabilities were $10.96 billion as of June 30, 2019, a decrease of $104.3 million from December 31, 2018. The decline was primarily due to a decrease in deposits partially offset by an increase in FHLB advances.

Investment Securities

At June 30, 2019, the Company’s investment portfolio primarily consisted of debt securities available for sale totaling $2.86 billion compared to $3.17 billion at December 31, 2018. The decrease in the debt securities portfolio from year-end is due to $439.5 million in maturities, repayments and sales and $9.5 million in premium amortization, offset by $91.6 million in net unrealized gain and $54.4 million in purchases. The average duration of our debt securities investment portfolio was approximately 4 years and 4 months at June 30, 2019. This duration takes into account calls, where appropriate, and consensus prepayment speeds.

The investment securities are used by the Company as a component of its balance sheet management strategies. From time-to-time, securities may be sold to reposition the portfolio in response to strategies developed by the Company’s asset liability management committee. In accordance with our investment strategy, management monitors market conditions with a view to realize gains on its available for sale securities portfolio when prudent.

The Company performs a quarterly assessment of the debt securities available for sale in its investment portfolio that have an unrealized loss to determine whether the decline in the fair value of these securities below their amortized cost basis is other-than-temporary. Impairment is considered other-than-temporary when it becomes probable that the Company will be unable to recover the entire amortized cost basis of its investment. The Company’s impairment assessment takes into consideration factors such as the length of time and the extent to which the market value has been less than cost, defaults or deferrals of scheduled interest or principal, external credit ratings and recent downgrades, internal assessment of credit quality, and whether the Company intends to sell the security and whether it is more likely than not it will be required to sell the security prior to recovery of its amortized cost basis. If a decline in fair value is judged to be other-than-temporary, the cost basis of the individual security is written down to fair value which then becomes the new cost basis. The new cost basis is not adjusted for subsequent recoveries in fair value.

When there are credit losses associated with an impaired debt security and the Company does not have the intent to sell the security and it is more likely than not that it will not have to sell the security before recovery of its cost basis, the Company will separate the amount of the impairment into the amount that is credit-related and the amount related to non-credit factors. The credit-related impairment is recognized in earnings and the non-credit-related impairment is recognized in accumulated other comprehensive income.

Table of Contents

At June 30, 2019, the market value of debt securities available for sale had a net unrealized gain of $48.4 million compared to a net unrealized loss of $43.2 million at December 31, 2018. The change in valuation was the result of fluctuations in market interest rates during the six months ended June 30, 2019. At June 30, 2019, the Company had $966.3 million of debt securities available for sale with gross unrealized losses of $12.6 million; however, we did not consider these investment securities to be other-than-temporarily impaired.

Credit Risk Management

The extension of credit in the form of loans or other credit substitutes to individuals and businesses is one of our principal commerce activities. Our policies, applicable laws, and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies, and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry and type of borrower and by limiting the aggregation of debt to a single borrower.

In analyzing our existing portfolio, we review our consumer and residential loan portfolios by their performance as a pool of loans, since no single loan is individually significant or judged by its risk rating, size or potential risk of loss. In contrast, the monitoring process for the commercial business, real estate construction, and commercial real estate portfolios includes periodic reviews of individual loans with risk ratings assigned to each loan and performance judged on a loan-by-loan basis.

We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. In the event that full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan. For additional discussion on our methodology in managing credit risk within our loan portfolio, see the “Allowance for Loan and Lease Losses” section in this Management’s Discussion and Analysis and Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of the Company’s 2018 Annual Report on Form 10-K.

Loan policies, credit quality criteria, portfolio guidelines and other controls are established under the guidance of our Chief Credit Officer and approved, as appropriate, by the Board of Directors. Credit Administration, together with the management loan committee, has the responsibility for administering the credit approval process. As another part of its control process, we use an internal credit review and examination function to provide reasonable assurance that loans and commitments are made and maintained as prescribed by our credit policies. This includes a review of documentation when the loan is initially extended and subsequent examination to ensure continued performance and proper risk assessment.

Total loans increased $255.5 million from year-end 2018 primarily the result of organic loan production, partially offset by principal pay downs. The loan portfolio continues to be diversified, with the intent to mitigate risk by monitoring concentration in any one sector. The $37.4 million in unearned income recorded at June 30, 2019 was comprised of $20.7 million in net purchase discounts and $16.7 million in net deferred loan fees. The $42.2 million in unearned income recorded at December 31, 2018 consisted of $26.1 million in net purchase discounts and $16.1 million in net deferred loan fees.

Commercial Loans: We are committed to providing competitive commercial lending in our primary market areas. Management expects a continued focus within its commercial lending products and to emphasize, in particular, relationship banking with businesses and business owners.

Real Estate Loans: One-to-four family residential loans are secured by properties located within our primary market areas and, typically, have loan-to-value ratios of 80% or lower at origination. Our underwriting standards for commercial and multifamily residential loans generally require that the loan-to-value ratio for these loans not exceed 75% of appraised value, cost, or discounted cash flow value, as appropriate, and that commercial properties maintain debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. However, underwriting standards can be influenced by competition and other factors. We endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.

Table of Contents

Real Estate Construction Loans: We originate a variety of real estate construction loans. Underwriting guidelines for these loans vary by loan type but include loan-to-value limits, term limits and loan advance limits, as applicable. Our underwriting guidelines for commercial and multifamily residential real estate construction loans generally require that the loan-to-value ratio not exceed 75% and stabilized debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. As noted above, underwriting standards can be influenced by competition and other factors. However, we endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.

Consumer Loans: Consumer loans include automobile loans, boat and recreational vehicle financing, home equity and home improvement loans and miscellaneous personal loans.

Foreign Loans: The Company has no material foreign activities. Substantially all of the Company’s loans and unfunded commitments are geographically concentrated in its service areas within the states of Washington, Oregon and Idaho.

PCI Loans: PCI loans are comprised of loans and loan commitments acquired in connection with the 2011 FDIC-assisted acquisitions of First Heritage Bank and Summit Bank, as well as the 2010 FDIC-assisted acquisitions of Columbia River Bank and American Marine Bank. PCI loans are generally accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”).

For additional information on our loan portfolio, including amounts pledged as collateral on borrowings, see Note 4 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Nonperforming Assets

Nonperforming assets consist of: (i) nonaccrual loans, which generally are loans placed on a nonaccrual basis when the loan becomes past due 90 days or when there are otherwise serious doubts about the collectability of principal or interest within the existing terms of the loan, (ii) OREO and (iii) OPPO, if applicable.

The following table sets forth, at the dates indicated, information with respect to our nonaccrual loans and total nonperforming assets:

Table of Contents

At June 30, 2019, nonperforming assets were $40.2 million, compared to $60.9 million at December 31, 2018. Nonperforming assets decreased $20.7 million during the six months ended June 30, 2019, primarily due to pay downs in nonaccrual commercial business loans and real estate loans. Additionally, we had $5.1 million in OREO sales during that time. For further information on OREO, see Note 6 of the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Allowance for Loan and Lease Losses

The ALLL is an accounting estimate of incurred credit losses in our loan portfolio at the balance sheet date. The provision for loan and lease losses is the expense recognized in the Consolidated Statements of Income to adjust the allowance to the levels deemed appropriate by management, as measured by the Company’s credit loss estimation methodologies. The ALLL for unfunded commitments and letters of credit is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities at the balance sheet date.

At June 30, 2019, our ALLL was $80.5 million, or 0.93% of total loans (excluding loans held for sale). This compares with an ALLL of $83.4 million, or 0.99% of total loans (excluding loans held for sale) at December 31, 2018 and an ALLL of $80.2 million or 0.95% of total loans (excluding loans held for sale) at June 30, 2018.

Liquidity and Sources of Funds

Our primary sources of funds are customer deposits. Additionally, we utilize advances from the FHLB, the FRB, and sweep repurchase agreements to supplement our funding needs. These funds, together with loan repayments, loan sales, retained earnings, equity and other borrowed funds are used to make loans, to acquire securities and other assets and to fund continuing operations.

In addition, we have a shelf registration statement on file with the SEC registering an unspecified amount of any combination of debt or equity securities, depositary shares, purchase contracts, units and warrants in one or more offerings. Specific information regarding the terms of and the securities being offered will be provided at the time of any offering. Proceeds from any future offerings are expected to be used for general corporate purposes, including, but not limited to, the repayment of debt, repurchasing or redeeming outstanding securities, working capital, funding future acquisitions or other purposes identified at the time of any offering.

Deposit Activities

Our deposit products include a wide variety of transaction accounts, savings accounts and time deposit accounts. Core deposits (demand deposit, savings, money market accounts and certificates of deposit less than $250,000) decreased $206.1 million from year-end 2018, shown in the table below.

We have established a branch system to serve our consumer and business depositors. In addition, management’s strategy for funding asset growth is to make use of brokered and other wholesale deposits on an as-needed basis. The Company participates in the CDARS^® program. CDARS^® is a network that allows participating banks to offer extended FDIC deposit insurance coverage on time deposits. The Company also participates in a similar program to offer extended FDIC deposit insurance coverage on money market accounts. These extended deposit insurance programs are generally available only to existing customers and are not used as a means of generating additional liquidity. At June 30, 2019, brokered deposits, reciprocal money market accounts and other wholesale deposits (excluding public deposits) totaled $338.3 million, or 3.3% of total deposits, compared to $395.2 million or 3.8% at year-end 2018. These deposits have varied maturities.

The following table sets forth the Company’s deposit base by type of product for the dates indicated:



	June 30, 2019					December 31, 2018
	Balance			% of Total		Balance			% of Total

Borrowings

We rely on FHLB advances and FRB borrowings as another source of both short and long-term funding. FHLB advances and FRB borrowings are secured by investment securities, and residential, commercial and commercial real estate loans. At June 30, 2019, we had FHLB advances of $495.5 million compared to $399.5 million at December 31, 2018.

During the second quarter of 2019, the Company entered into a $30.0 million short-term credit facility with an unaffiliated bank. This facility provides the Company additional liquidity, if needed, for various corporate activities including the repurchase of shares of Columbia Banking System, Inc. common stock. The credit agreement requires the Company to comply with certain covenants including those related to asset quality and capital levels.

We also utilize wholesale and retail repurchase agreements to supplement our funding sources. Our wholesale repurchase agreements are secured by mortgage-backed securities. At June 30, 2019 and December 31, 2018, we had deposit customer sweep-related repurchase agreements of $50.2 million and $61.1 million, respectively, which mature on a daily basis. Management anticipates we will continue to rely on FHLB advances, FRB borrowings and wholesale and retail repurchase agreements in the future and we will use those funds primarily to make loans and purchase securities.

Contractual Obligations, Commitments & Off-Balance Sheet Arrangements

We are party to many contractual financial obligations, including repayment of borrowings, operating and equipment lease payments, off-balance sheet commitments to extend credit and investments in affordable housing partnerships. At June 30, 2019, we had commitments to extend credit of $2.62 billion compared to $2.65 billion at December 31, 2018.

Capital Resources

Shareholders’ equity at June 30, 2019 was $2.13 billion, compared to $2.03 billion at December 31, 2018. Shareholders’ equity was 16% of total period-end assets at both June 30, 2019 and December 31, 2018.

Regulatory Capital

In July 2013, the federal bank regulators approved the Capital Rules (as discussed in our 2018 Annual Report on Form 10-K, “Item 1. Business—Supervision and Regulation and —Regulatory Capital Requirements”), which implement the Basel III capital framework and various provisions of the Dodd-Frank Act. We and the Bank were required to comply with these rules as of January 1, 2015, subject to the phase-in of certain provisions, which was completed as of January 1, 2019. We believe that, as of June 30, 2019, we and the Bank meet all capital adequacy requirements under the Capital Rules on a fully phased-in basis.

FDIC regulations set forth the qualifications necessary for a bank to be classified as “well-capitalized,” primarily for assignment of FDIC insurance premium rates. Failure to qualify as “well-capitalized” can negatively impact a bank’s ability to expand and to engage in certain activities. The Company and the Bank qualified as “well-capitalized” at June 30, 2019 and December 31, 2018.

The following table presents the capital ratios and the capital conservation buffer, as applicable, for the Company and its banking subsidiary at June 30, 2019 and December 31, 2018:



	Company				Columbia Bank
	June 30, 2019		December 31, 2018		June 30, 2019		December 31, 2018

Stock Repurchase Program

As described in our Annual Report on Form 10-K for the year ended December 31, 2018, our board of directors approved a stock repurchase program to repurchase up to 2.9 million shares, up to a maximum aggregate purchase price of $100.0 million. The Company intends to purchase the shares from time to time in the open market or in private transactions, under conditions which allow such repurchases to be accretive to EPS while maintaining capital ratios that exceed the guidelines for a well-capitalized financial institution. During the quarter, the Company repurchased 624 thousand shares of common stock totaling $21.9 million.

Non-GAAP Financial Measures

The Company considers operating net interest margin (tax equivalent) to be a useful measurement as it more closely reflects the ongoing operating performance of the Company. Additionally, presentation of the operating net interest margin allows readers to compare certain aspects of the Company’s net interest margin to other organizations that may not have had significant acquisitions. Despite the usefulness of the operating net interest margin (tax equivalent) to the Company, there is no standardized definition for it and, as a result, the Company’s calculations may not be comparable with other organizations. The Company encourages readers to consider its Consolidated Financial Statements in their entirety and not to rely on any single financial measure.

The following table reconciles the Company’s calculation of the operating net interest margin (tax equivalent) to the net interest margin (tax equivalent) for the periods indicated:



	Three Months Ended June 30,						Six Months Ended June 30,
	2019			2018			2019			2018
Operating net interest margin non-GAAP reconciliation:	(dollars in thousands)
Net interest income (tax equivalent) (1)	$	127,236		$	118,602		$	250,346		$	235,961
Adjustments to arrive at operating net interest income (tax equivalent):
Incremental accretion income on FDIC PCI loans	(579		)	(326		)	(867		)	(655		)
Incremental accretion income on other acquired loans	(2,084		)	(2,690		)	(3,831		)	(6,060		)
Premium amortization on acquired securities	1,651			2,131			3,430			4,206
Interest reversals on nonaccrual loans	662			253			1,288			670
Operating net interest income (tax equivalent) (1)	$	126,886		$	117,970		$	250,366		$	234,122
Average interest earning assets	$	11,606,727		$	11,052,807		$	11,584,301		$	11,087,587
Net interest margin (tax equivalent) (1)(2)	4.40		%	4.30		%	4.36		%	4.29		%
Operating net interest margin (tax equivalent) (1)(2)	4.38		%	4.28		%	4.36		%	4.26		%

__________

(1) Tax-exempt interest income has been adjusted to a tax equivalent basis. The amount of such adjustment was an addition to net interest income of $2.1 million and $1.9 million for the three months ended June 30, 2019 and 2018, respectively, and an addition to net interest income of $4.2 million and $3.8 million for the six months ended June 30, 2019 and 2018, respectively.

(2) Beginning January 2019, net interest margin (tax equivalent) and operating net interest margin (tax equivalent) were calculated using the actual number of days and on an actual/actual basis. This change was done to provide more meaningful trend information for our NIM regardless of the number of days in the period. Prior periods, which were previously reported on a 30/360 basis, have been restated to conform to the current basis.

Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A number of measures are used to monitor and manage interest rate risk, including income simulations and interest sensitivity (gap) analysis. An income simulation model is the primary tool used to assess the direction and magnitude of changes in net interest income resulting from changes in interest rates. Basic assumptions in the model include prepayment speeds on mortgage-related assets, cash flows and maturities of other investment securities, loan and deposit volumes and pricing. These assumptions are inherently subjective and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes and changes in market conditions and management strategies, among other factors. At June 30, 2019, based on the measures used to monitor and manage interest rate risk, there has not been a material change in the Company’s interest rate risk since December 31, 2018. For additional information, refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2018 Annual Report on Form 10-K.


Item 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the Company’s management, including the CEO and CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934). Based on that evaluation, the CEO and CFO have concluded that as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that the information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934 is (i) accumulated and communicated to our management (including the CEO and CFO) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Controls Over Financial Reporting

There was no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
