NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

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, 2020 are not necessarily indicative of results to be anticipated for the year ending December 31, 2020. The accompanying interim unaudited Consolidated Financial Statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2019 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 2019 Annual Report on Form 10-K. In addition to the changes already disclosed in the Annual Report on Form 10-K regarding ASC 326, this ASC also made changes to the accounting for available for sale securities. One such change is to require credit losses to be presented as an allowance rather than a write-down on available for sale securities, which refers to securities management does not intend to sell or with respect to which management believes that it is more likely than not they will not be required to sell. With the exception of that change, there have not been any changes in our significant accounting policies compared to those contained in our 2019 Form 10-K disclosure for the year ended December 31, 2019.

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 shareholders’ equity as previously reported.


2.	Accounting Pronouncements Recently Adopted or Issued

Accounting Standards Adopted in 2020

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. As the ASU focused on clarifying certain aspects of accounting, adoption of this ASU did not have a material impact on the Company’s Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) - 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 requires that credit losses be presented as an allowance rather than as a write-down. In November 2019, the FASB subsequently issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. The amendments in the update require entities to include expected recoveries of the amortized cost basis previously written-off or expected to be written-off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13.

Table of Contents

Unlike the incurred loss models, the CECL model in ASU 2016-13 does not specify a threshold for the recognition of an impairment allowance. Rather, the Company recognizes an impairment allowance equal to its estimate of lifetime expected credit losses, adjusted for prepayments, for in-scope financial instruments. Accordingly, the impairment allowance measured under the CECL model is expected to change significantly from the impairment allowance measured under the Company’s incurred loss model. The Company engaged a third-party vendor to assist in the CECL calculation and has developed and implemented an internal governance framework. The amendments in ASU 2016-13 and the above ASUs related to credit losses are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption was permitted, including adoption in any interim period. The Company adopted the new standards, using a modified retrospective approach, effective January 1, 2020, which resulted in an increase of $1.6 million to its allowance for credit losses, an increase of $1.6 million to its allowance for unfunded commitments and letters of credit and a net-of-tax cumulative-effect adjustment of $2.5 million to decrease the beginning balance of retained earnings.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU adds, eliminates and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The ASU is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the added disclosure requirements until their effective date. The Company adopted the new standard effective January 1, 2020. The adoption of this ASU did not have a material impact on the Company’s Consolidated Financial Statements.

Recently Issued Accounting Standards, Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In response to concerns about structural risks of the cessation of LIBOR, the amendments in this ASU provide optional guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. The amendments in this ASU are elective and are effective March 12, 2020 for all entities. The adoption of this ASU is not expected to have a material impact on the Company’s Consolidated Financial Statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The guidance issued in this ASU simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities for outside basis differences. This ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The ASU is effective for interim and annual reporting periods beginning after December 15, 2020; early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s Consolidated Financial Statements.

A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income. There were no amounts of accrued interest reversed against interest income for the three and six months ended June 30, 2020 and 2019.

Accrued interest receivable for securities available for sale is included in “Interest receivable” on the Company’s Consolidated Balance Sheet and is not reflected in the balances in the table above. At June 30, 2020 and December 31, 2019, accrued interest receivable for securities was $12.6 million and $13.9 million, respectively. The Company does not measure an allowance for credit losses for accrued interest receivable.

The following table provides the proceeds and both gross realized gains and losses on sales of debt securities available for sale as well as other securities gains and losses for the periods indicated:

(1) Visa Class B restricted stock owned by the Company was previously carried at a zero-cost basis due to existing transfer restrictions and uncertainty of covered litigation. The sale of shares by the Company of Visa Class B restricted shares during the three months ended June 30, 2020 resulted in an observable market price. As a result, the Company adjusted the carrying value of its remaining shares of Visa Class B restricted shares upward to this observable market price.

At June 30, 2020, there were 57 U.S. government agency and government-sponsored enterprise mortgage-backed securities and collateralized mortgage obligation securities in an unrealized loss position. 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 concluded an allowance for credit losses is unnecessary at June 30, 2020.

At June 30, 2020, there were two other asset-backed securities in an unrealized loss position. 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 concluded an allowance for credit losses is unnecessary at June 30, 2020.

At June 30, 2020, there were five state and municipal government securities in an unrealized loss position. 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, 2020, 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 concluded an allowance for credit losses is unnecessary at June 30, 2020.

Equity Securities without Readily Determinable Fair Values

Visa Class B Restricted Shares

In 2008, the Company received Visa Class B restricted shares as part of Visa’s initial public offering. These shares are transferable only under limited circumstances until they can be converted into publicly traded Visa Class A common shares. This conversion will not occur until the settlement of certain litigation which is indemnified by Visa members, including the Company. Visa funded an escrow account from its initial public offering to settle these litigation claims. Should this escrow account not be sufficient to cover these litigation claims, Visa is entitled to fund additional amounts to the escrow account by reducing each member bank’s Visa Class B conversion ratio to unrestricted Visa Class A shares.

During the three months ended June 30, 2020, the Company sold 17,360 shares of Visa Class B restricted stock for a gain of $3.0 million, which resulted in an observable market price. As a result, the Company adjusted the carrying value of its remaining Visa Class B restricted shares upward to this observable market price. At June 30, 2020, the Company owned 77,683 Visa Class B shares, which had a carrying value of $13.4 million.

Loan payments are considered timely when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof is received on the due date of the scheduled payment. In addition, the risk rating on COVID-19 modified loans did not change. These loans are not considered past due until after the deferral period is over and scheduled payments resume. Accrued interest on these COVID-19 modified loans is due, in full, when the deferral period ends. The credit quality of these loans will be reevaluated after the deferral period ends.

Nonaccrual loans are generally loans placed on a nonaccrual basis when they become 90 days past due or when there are otherwise serious doubts about the collectability of principal or interest within the existing terms of the loan. The Company’s policy is to write-off all accrued interest on loans when they are placed on nonaccrual status.

The following table summarizes written off interest on nonaccrual loans for the three and six months ended June 30, 2020 and 2019:

The Company’s loans classified as TDR are loans that have been modified or with respect to which 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. Loans classified as TDR are included with the loans collectively measured for credit losses.

The Company had commitments to lend $625 thousand of additional funds on loans classified as TDR as of June 30, 2020. The Company had $1.1 million of such commitments at December 31, 2019. The Company did not have any loans modified as TDR that defaulted within 12 months of being modified as TDR during the three and six months ended June 30, 2020. During the three and six months ended June 30, 2019, the Company had one $26 thousand consumer loan that defaulted within 12 months of being modified as a TDR. The defaulted TDR loan was collateralized and included with the loans individually measured for credit loss.

Loan modifications and PPP loans in response to COVID-19

Financial institutions are required to maintain records of the volume of loans involved in modifications to which troubled debt restructuring relief is applicable. At June 30, 2020, the Company granted approximately 3,050 short–term deferments on loan balances of $1.58 billion, which represented 16% of total loan balances as of June 30, 2020. These short–term deferments are not classified as TDRs and will not be reported as past due provided that they are performing in accordance with the modified terms.

The Company offered PPP loans to provide financial support to small and medium-size businesses to cover payroll and certain other expenses during the COVID-19 pandemic. The PPP was established by the CARES Act and is implemented by the U.S. SBA with support from the U.S. Department of Treasury. The program, which was amended by the Paycheck Protection Flexibility Act of 2020, provides small businesses with funds to pay up to 24 weeks of payroll costs including benefits, as well as interest on mortgages, rent and utilities. Funds are provided to small businesses in the form of loans that will be fully forgiven when used for permitted purposes and when at least 60% of the funds are used for payroll costs in accordance with the requirements of the amended PPP. At June 30, 2020, we had $941.4 million of PPP loans outstanding, which are included in commercial business loans.


5.	Allowance for Credit Losses and Allowance for Unfunded Commitments and Letters of Credit

The ACL is determined through quarterly assessments of expected credit losses within the loan portfolio and is deducted from the loan’s amortized cost basis to present the net amount of loans expected to be collected. We estimate the ACL using relevant and reliable available information, which is derived from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Additions to and recaptures from the ACL are charged to current period earnings through the provision for credit losses. Loan amounts that are determined to be uncollectable are charged directly against the ACL and netted against amounts recovered on previously charged-off loans.

For the purpose of calculating portfolio level reserves, we have segmented our loan portfolio into two portfolio segments (Commercial and Consumer). The Commercial and Consumer portfolio segments are then further broken down into loan classes by risk characteristics. The risk characteristics include regulatory call codes, type of industry and collateral type.

The ACL is comprised of reserves measured on a collective (pool) basis using a quantitative DCF model for all loan classes with similar risk characteristics and then qualitatively adjusted for large loan concentrations, trends in problem loans, policy exemptions granted, and other factors. The quantitative DCF model utilizes anticipated period cash flows determined on a loan-level basis. The anticipated cash flows take into account contractual principal and interest payments, anticipated segment level prepayments, probability of defaults and historical loss given defaults. The majority of our loan classes utilize regression models to calculate probability of defaults, in which macroeconomic factors are correlated to historical quarterly defaults. The Commercial segment two-factor models utilize a mix of seven macroeconomic factors, including the four most commonly used factors: Real GDP, National Unemployment Rate, Home Price Index and Commercial Real Estate Index. The three additional factors are Nominal GDP, Producer Price Index and Core Consumer Price Index. The Consumer segment two-factor models utilize a mix of three macroeconomic factors: National Unemployment Rate, Home Price Index and Prime Rate. The Company utilizes an 18 month reasonable and supportable forecast for the macroeconomic factors, after which they revert to their historical mean using a straight-line basis constructed on their absolute historical quarterly change.

Loans are individually measured for credit losses if they do not share similar risk characteristics of other loans within their respective pools. Individually measured loans are primarily nonaccrual and collateral dependent with balances equal to or greater than $500,000 and for which foreclosure is probable. Commercial real estate loans are secured by commercial real estate, including owner occupied and non-owner occupied commercial real estate, as well as multifamily residential real estate. Commercial business loans are primarily secured by non-real estate collateral, including equipment and other non-real estate fixed assets, inventory, receivables, and cash. Agricultural loans are secured by farmland and other agricultural real estate, as well as equipment, inventory, such as crops and livestock, non-real estate fixed assets, and cash. Construction loans are secured by one-to-four family residential real estate and commercial real estate in varying stages of development. One-to-four family residential real estate loans are secured by one-to-four family residential properties. Other consumer loans are secured by personal property. For loans measured on an individual basis, the Company calculates the allowance as the difference between the amortized cost of the loan and the fair market value of the collateral. The fair market value of the collateral is determined by either the discounted expected future cash flows from the operation of the collateral or the appraised value of the collateral, less costs to sell. If the fair value of the collateral is greater than the amortized cost of the loan, no reserve is recorded.

The Company also records an allowance for credit losses on unfunded loan commitments and letters of credit. We estimate expected credit losses on unfunded commitments in which we are exposed to credit risk, unless we have the option to unconditionally cancel the obligation. Expected credit losses are calculated based on the likelihood that funding will occur and an estimate of what will be funded by analyzing the most recent four-quarter utilization rates, current utilization, and our quantitative ACL rate. The allowance for unfunded commitments and letters of credit is included in “Other Liabilities” on the Consolidated Balance Sheets, with changes to the balance being charged to noninterest expense.

We do not measure an allowance for credit losses on accrued interest receivable balances because these balances are written-off in a timely manner as a reduction to interest income when loans are placed on nonaccrual status.

The $67.6 million increase in the ACL at June 30, 2020 compared to the ALLL at December 31, 2019 was primarily the result of COVID-19 and the corresponding downturn in the national and world economies. The ACL at June 30, 2020 does not include a reserve for the PPP loans as these loans are fully guaranteed by the SBA.

Changes in the allowance for unfunded commitments and letters of credit, a component of “Other liabilities” in the Consolidated Balance Sheets, are summarized as follows:

Credit Quality Indicators

The extension of credit in the form of loans or other credit products to consumer and commercial clients 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.

We evaluate the credit quality of our loan portfolio using regulatory risk ratings, which are based on relevant information about the borrower’s financial condition, including current financial condition, historical payment experience, credit documentation and current economic trends. Risk ratings are reviewed and updated whenever appropriate, with more periodic reviews as the risk and dollar value of the loss on the loan increases. All loans risk rated special mention or worse with amortized costs exceeding $100,000 are reviewed at least quarterly with more frequent review for specific loans.

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 Company performed an annual impairment assessment as of July 31, 2019 and concluded that there was no impairment. As of June 30, 2020, we evaluated potential triggering events that might be indicators that our goodwill was impaired. The events include the economic disruption and uncertainty surrounding the COVID-19 pandemic and the recent volatility in stock prices. Based on our evaluation, we concluded that our goodwill was not more than likely impaired.

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.	Revolving Line of Credit

The Company has a $15.0 million short-term credit facility with an unaffiliated bank that expires May 27, 2021. This facility has a variable interest rate and provides the Company additional liquidity, if needed, for various corporate activities including the repurchase of shares of Columbia Banking System, Inc. common stock. There was no outstanding balance at both June 30, 2020 and December 31, 2019. 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, 2020.


9.	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 interest rate-based 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 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.

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 $10.6 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, 2020 and December 31, 2019 was $533.8 million and $428.6 million, respectively. During both the three and six month periods ended June 30, 2020, there was mark-to-market loss of $473 thousand recorded to “Other” noninterest expense. During both the three and six months ended June 30, 2019, there was mark-to-market loss of $2 thousand recorded to “Other” noninterest expense.

Interest rate collar	$	26,825	$	15,691	Interest income	$	3,130	$	—

The notional amount of the interest rate collar was $500.0 million at June 30, 2020. The cash flow hedge was determined to be effective during the periods presented and, as a result, qualifies for hedge accounting treatment.

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 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

Gross amount of recognized liabilities for repurchase agreements									51,479
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 $51.5 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.


10.	Commitments and Contingent Liabilities

Lease Commitments: The Company’s lease commitments consist primarily of leased locations under various non-cancellable operating leases that expire between 2020 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.

Table of Contents

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, 2020 and December 31, 2019, the Company’s loan commitments amounted to $2.65 billion and $2.67 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 $24.1 million and $25.7 million at June 30, 2020 and December 31, 2019, respectively. In addition, there were no commitments under commercial letters of credit used to facilitate customers’ trade transactions and other off-balance sheet liabilities at both June 30, 2020 and December 31, 2019.

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.


11.	Shareholders’ Equity

Dividends:

The following table summarizes year-to-date dividend activity as of June 30, 2020:



Declared	Regular Cash Dividends Per Common Share		Special Cash Dividends Per Common Share		Record Date	Paid Date
January 23, 2020	$	0.28	$	0.22	February 5, 2020	February 19, 2020
April 30, 2020	$	0.28	$	—	May 14, 2020	May 28, 2020

Subsequent to quarter end, on July 23, 2020, the Company declared a regular quarterly cash dividend of $0.28 per common share payable on August 19, 2020 to shareholders of record at the close of business on August 5, 2020.

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 months ended June 30, 2020, the Company did not purchase any common shares under the share repurchase program. For the six months ended June 30, 2020, the Company repurchased 731 thousand shares of common stock at an average price of $27.36 per share. The Company’s share repurchase authorization expired in May of 2020.

13.	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:

Debt securities available for sale 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 debt securities available for sale.

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.

Nonrecurring Measurements

Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as collateral dependent loans. The following valuation techniques and inputs were used to estimate the fair value of collateral dependent loans.

Collateral dependent loans - A collateral dependent loan is a loan in which repayment is expected to be provided solely by the underlying collateral. The fair market value of the collateral is determined by either the discounted expected future cash flows from the operation of the collateral or the appraised value of the collateral, less costs to sell. The collateral dependent loan valuations are performed in conjunction with the allowance for credit losses process on a quarterly basis.

Equity securities without readily determinable fair value - The Company measures equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer, with such changes recognized in earnings. Our equity securities without readily determinable fair value consist of 77,683 Visa Class B shares. These shares are currently subject to certain transfer restrictions and will be convertible into Visa Class A shares upon final resolution of certain litigation matters involving Visa. For additional information, please see Note 3 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

The following table presents the carrying value of equity securities, without readily determinable fair values, still held as of June 30, 2020, that are measured under the measurement alternative and related adjustments recorded during the periods presented for those securities with observable price changes. These securities are included in the nonrecurring fair value tables when applicable price changes are observable.

14.	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, 2020 and 2019:

15.	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, 2020 and 2019:

CRITICAL ACCOUNTING POLICIES

Management has identified the accounting policies related to the ACL, 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 “Adoption of Allowance for Credit Losses - ASC 326,” “Business Combinations” and “Valuation and Recoverability of Goodwill” in our 2019 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 2019 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.

COVID-19 Update

We continue to closely monitor the progress of COVID-19 and to adapt our business in response to the pandemic to provide support for our team members and clients. We are staying in close contact with team members who have concerns or potential exposure in order to determine the best actions to maintain employee and client safety. Team members with the ability to work remotely have been encouraged to continue doing so while branches and offices have implemented disinfecting protocols and social distancing policies. Our comprehensive disinfecting protocols and social distancing and face-covering guidance meet or exceed requirements of all of our health department jurisdictions, and we are updating and adjusting those requirements as the situation evolves, and communicating expectations across our footprint. Our multi-layered safety plan incorporates a lot of flexibility, including remote work when practical, and it is working well to minimize opportunities for infection within the bank.

Our branch lobbies have remained open and we have encouraged the use of the drive through for social distancing purposes. Branch hours have been adjusted on a case by case basis depending upon employee availability. No branch has had their hours changed or closed for an extended period of time. Our clients have received support through payment deferral programs as well as a variety of options from the SBA including the PPP, the Economic Injury Disaster Loan and other deferral and automatic debt relief programs. Our participation in the PPP will increase our loan balances and loan interest income over the period those loans are outstanding. As of June 30, 2020, we had $941.4 million of PPP loans outstanding and had granted short-term payment deferrals on $1.58 billion of loans.

We have launched two community focused initiatives in response to the pandemic, putting more than $1 million to work in support of our local communities. The Pass It On Project is designed to provide small businesses more than $500,000 to perform services for community members whose lives have been adversely impacted by the pandemic or the economic downturn it caused. The program will support more than 350 small businesses and many more individuals in the Northwest as we continue to manage through the pandemic and economic recovery. The COVID-19 Community Relief fund put more than $500,000 in the hands of 25 non-profit organizations working to provide relief for those affected by the pandemic in the Northwest. We have also been working with our non-profit community partners by lifting restrictions on sponsorships and contributions to allow organizations to rededicate the funds to COVID-19 response and recovery.

The measures we have taken in response to the pandemic have enabled us to continue all operations as COVID-19 spread in the Northwest. We continue to monitor the pandemic and adjust our response in concert with local government and healthcare officials.

For additional information on the impact and potential impact of COVID-19 on our business, financial condition, liquidity, capital and results of operations, see Part II Item 1A “Risk Factors” of this report.

Earnings Summary

Comparison of current quarter to prior year period

The Company reported net income for the second quarter of $36.6 million or $0.52 per diluted common share, compared to $51.7 million or $0.71 per diluted common share for the second quarter of 2019. Net interest income for the three months ended June 30, 2020 was $121.9 million, a decrease of $3.3 million from the prior year period. The decrease was a result of a reduction in interest income on loans due to the lower rate environment partially offset by an increase in interest income on loans and securities due to higher average balances. The decrease in interest income was also partially offset by favorable decreases in interest expense from interest-bearing deposits and FHLB advances resulting from lower rates.

The provision for credit losses for the second quarter of 2020 was $33.5 million compared to $218 thousand for the second quarter of 2019. The increase in provision expense for the second quarter of 2020 compared to one year ago was principally the result of COVID-19 and the corresponding downturn in local, national and world economies as well as increased unemployment rates.

Noninterest income for the current quarter was $37.3 million, an increase of $11.6 million from the prior year period. The increase was principally due to the sale of Visa Class B restricted stock that resulted in an observable market price and subsequent upward adjustment to the carrying value of remaining shares for a total gain of $16.4 million. Partially offsetting these gains were decreases in deposit account and treasury management fees and a BOLI benefit that was recognized during the second quarter of 2019.

Total noninterest expense for the quarter ended June 30, 2020 was $80.8 million, a decrease of $5.9 million from the prior year period. This decrease was primarily driven by the lower compensation and benefits expense related to the deferral of labor costs for the PPP loans. Legal and professional fees also declined but were partially offset by an increase in other expenses.

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

The Company reported net income for the six months ended June 30, 2020 of $51.2 million or $0.72 per diluted common share, compared to $97.6 million or $1.33 per diluted common share for the same period in 2019. Net interest income for the six months ended June 30, 2020 was $244.3 million, a decrease of $1.9 million from the prior year period. The decrease was a result of a reduction in interest income on loans due to the lower rate environment partially offset by increases in interest income on loans and securities due to higher average balances. The decrease in interest income was also partially offset by favorable decreases in interest expense from interest-bearing deposits and FHLB advances primarily resulting from lower rates.

The provision for credit losses for the six months ended June 30, 2020 was $75.0 million compared to a provision of $1.6 million for the first six months of 2019. The increase in the provision for the first six months of 2020 compared to the same period in 2019 was due to the ongoing COVID-19 pandemic which has negatively affected the economy and increased unemployment rates, similar to the quarterly results above.

Noninterest income for the six months ended June 30, 2020 was $58.5 million, an increase of $11.1 million from the prior year period. The increase was primarily due to the previously noted $16.4 million gain from the sale and upward adjustment to the carrying value of the Visa Class B restricted shares to the market price and loan revenue. These increases were partially offset by decreases in deposit account and treasury management fees.

For the six months ended June 30, 2020, noninterest expense was $165.1 million, a decrease of $6.3 million from $171.4 million for the same period in 2019. The decrease from the prior year period was driven by lower legal and professional fees, compensation and employee benefits and B&O tax expenses which were partially offset by higher other expenses.

Comparison of current quarter to prior year period

Net interest income for the second quarter of 2020 was $121.9 million, down from $125.1 million for the same quarter in 2019. The decrease was a result of a reduction in interest income on loans due to the lower rate environment. This decrease was partially offset by the increase in the average balance of the loan portfolio, an increase in interest income from securities due to higher average balances and decreases in interest expense on interest-bearing deposits and FHLB advances due to lower rates.

The Company’s net interest margin (tax equivalent) decreased to 3.64% in the second quarter of 2020, from 4.40% for the prior year period. This decrease was driven by lower rates on the loan and securities portfolios as well as higher average interest-earning deposits with banks. The Company’s operating net interest margin (tax equivalent)⁽¹⁾ decreased to 3.64% from 4.38% during the second quarter of 2019. The decrease was due to the items previously noted for the decrease in the net interest margin.

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

The results for the first half of 2020 compared to the same period in 2019 were similar to the quarterly results. Net interest income for the six months ended June 30, 2020 was $244.3 million, relative to $246.1 million for the prior year period. The decrease in net interest income on loans was due to the lower rate environment partially offset by increases in interest income on loans and securities due to higher average balances. The decrease in interest income was also partially offset by favorable decreases in interest expense from interest-bearing deposits and FHLB advances primarily resulting from lower rates.

(1) Operating net interest margin (tax equivalent) is a non-GAAP financial measure. See the “Non-GAAP financial measures” section in this Management’s Discussion and Analysis.

Table of Contents

The Company’s net interest margin (tax equivalent) decreased to 3.82% for the first six months of 2020, from 4.36% for the prior year period. The decrease in the Company’s net interest margin (tax equivalent) was a result of lower rates on our loans and securities, partially offset by lower rates on the deposits and FHLB borrowings. The Company’s operating net interest margin (tax equivalent) for the six months ended June 30, 2020 was 3.82% compared to 4.36% for the six months ended June 30, 2019. The decrease was due to the items previously noted for the decrease in the net interest margin.

Provision for Credit Losses

Comparison of current quarter to prior year period

During the second quarter of 2020, the Company recorded a $33.5 million net provision for credit losses, under the CECL methodology, compared to a $218 thousand net provision, under the previous ALLL methodology, during the second quarter of 2019. The increase in provision expense for the second quarter of 2020 compared to one year ago was principally the result of the COVID-19 pandemic and the corresponding downturn in local, national and world economies as well as increased unemployment rates. As a result, we have increased our reserves for lifetime credit losses.

The net provision for credit losses recorded during the current quarter also included management’s ongoing assessment of the credit quality of the Company’s loan portfolio. Other 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 2020. The amount of provision was calculated in accordance with the Company’s methodology for determining the ACL, discussed in Note 5 to the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

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

The provision for credit losses for the six months ended June 30, 2020 was $75.0 million compared to $1.6 million during the same period in 2019. The increase in the provision for the first six months of 2020 was due to the same factors discussed above for the quarterly provision for credit losses. The amount of provision was calculated in accordance with the Company’s methodology for determining the ACL, 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 $37.3 million for the second quarter of 2020, compared to $25.6 million for the same period in 2019. The increase was principally due to the sale of 17,360 shares of Visa Class B restricted stock for a gain of $3.0 million which resulted in an observable market price. As a result, the Company wrote up its remaining 77,683 Visa Class B restricted shares to fair value resulting in a gain of $13.4 million, for a total gain of $16.4 million. Based on the transfer restrictions and uncertainty of Visa’s covered litigation, the Visa Class B restricted shares were previously carried at a zero-cost basis. Partially offsetting these gains were decreases of $1.2 million in overdraft fees, $1.1 million in treasury management fees and a $3.0 million BOLI benefit that was recognized during the second quarter of 2019. The decrease in overdraft fees was due to an overall decrease in the number of transactions during this period as a result of the COVID-19 pandemic as well as clients generally carrying higher balances in their deposit accounts.

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

For the six months ended June 30, 2020, noninterest income was $58.5 million compared to $47.3 million for the same period in 2019, an increase of $11.1 million. The increase was primarily due to the previously noted $16.4 million gain from the sale and write-up of Visa Class B restricted shares to fair value during the second quarter of 2020. Loan revenue increased during the first half of 2020 due to increases in investor premiums earned due to a higher volume of mortgage loan originations through our held for sale program and interest rate swap income. These increases were partially offset by decreases in treasury management fees and overdraft fees which are included in the deposit account and treasury management fees line item in the table above.

Comparison of current quarter to prior year period

Noninterest expense was $80.8 million for the second quarter of 2020, a decrease of $5.9 million from $86.7 million for the prior year period. This decrease was primarily driven by lower compensation and employee benefits and legal and professional expenses partially offset by higher other expenses. The decline in compensation and employee benefits was due to labor costs capitalized related to the origination of PPP loans during the second quarter of 2020 which reduced compensation and benefits expense. These labor costs are capitalized and amortized as a reduction in interest income over the life of the loan. Legal and professional fees also declined compared to the same period in 2019 primarily due to lower expenses tied to digital corporate initiatives. Partially offsetting these decreases was a $2.6 million increase in the provision for unfunded loan commitments which is included in other noninterest expense in the table above.

Table of Contents

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

For the six months ended June 30, 2020, noninterest expense was $165.1 million, compared to $171.4 million for the same period in 2019, a decrease of $6.3 million. The decrease from the prior year period was driven by lower legal and professional fees, compensation and employee benefits and B&O tax expenses which were partially offset by higher other expenses. Legal and professional fees were down compared to the same period in 2019 primarily due to lower expenses tied to digital corporate initiatives. The decrease in compensation and benefits was similar to the quarterly results which related to the capitalization of labor costs on the origination of PPP loans while B&O taxes were down due to a refund received for taxes paid in prior periods. Partially offsetting these decreases was an increase in the provision for unfunded loan commitments which is included in other noninterest expense in the table above.

The provision for unfunded loan commitments for the periods indicated are as follows:

Income Taxes

We recorded an income tax provision of $8.2 million for the second quarter of 2020, compared to a provision of $12.1 million for the same period in 2019, with effective tax rates of 18% and 19% for the second quarter of 2020 and 2019, respectively. For the six months ended June 30, 2020 and 2019, we recorded income tax provisions of $11.4 million and $22.9 million, respectively, with effective tax rates of 18% for the current year and 19% 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, 2019.

FINANCIAL CONDITION

Total assets were $15.92 billion at June 30, 2020, an increase of $1.84 billion from December 31, 2019. Cash and cash equivalents increased $850.0 million. Loans increased $1.03 billion during the first six months of 2020, which was primarily the result of new loan production, supplemented by PPP loans, partially offset by payments. Debt securities available for sale were $3.69 billion at June 30, 2020, a decrease of $52.4 million from December 31, 2019. Total liabilities were $13.64 billion as of June 30, 2020, an increase of $1.72 billion from December 31, 2019. The increase was primarily due to an increase in deposits driven by PPP loan funds being deposited into our clients’ deposit accounts, partially offset by a decrease in FHLB advances.

Investment Securities

At June 30, 2020, the Company’s investment portfolio primarily consisted of debt securities available for sale totaling $3.69 billion compared to $3.75 billion at December 31, 2019. The decrease in the debt securities portfolio from year-end is due to $458.9 million in maturities, repayments and sales and $12.1 million in premium amortization offset by $259.2 million in purchases and $159.4 million in net unrealized gain. The average duration of our debt securities investment portfolio was approximately 4 years and 6 months at June 30, 2020. 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 has resulted in a credit loss. A credit loss exists 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 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 determined to result in a credit loss, an allowance is recorded.

Table of Contents

When there are credit losses associated with a 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 through an allowance and the non-credit-related impairment is recognized in accumulated other comprehensive income.

At June 30, 2020, the market value of debt securities available for sale had a net unrealized gain of $202.5 million compared to a net unrealized gain of $43.0 million at December 31, 2019. The change in valuation was the result of fluctuations in market interest rates during the six months ended June 30, 2020. At June 30, 2020, the Company had $124.0 million of debt securities available for sale with gross unrealized losses of $1.5 million; however, we did not consider these investment securities to have an indicated credit loss.

The following table sets forth our securities portfolio by type for the dates indicated:

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, as well as 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 individually measured allowance is required for collateral dependent nonaccrual loans with balances equal to or greater than $500,000 and with respect to which foreclosure is probable. For the individually measured collateral dependent nonaccrual loan, the allowance for credit losses is equal to the difference between amortized cost of the loan and the determined value of the collateral. However, if the determined value of the collateral is greater than the amortized cost of the loan, no allowance for credit losses will be added for these loans.

For additional discussion on our methodology in managing credit risk within our loan portfolio, see the “Allowance for Credit 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 2019 Annual Report on Form 10-K.

Table of Contents

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. Examinations are performed to ensure continued performance and proper risk assessment.

Loan Portfolio Analysis

Our wholly owned banking subsidiary Columbia State Bank is a full service commercial bank, which originates a wide variety of loans, and focuses its lending efforts on originating commercial real estate and commercial business loans.

Total loans increased $1.03 billion from year-end 2019. This increase was primarily the result of providing $941.6 million of PPP loans, net of $19.6 million in net deferred fees at June 30, 2020. The PPP loans were originated to provide financial support to small and medium-size businesses to cover payroll and certain other expenses during the COVID-19 pandemic. To further assist our borrowers, the Company also offered short-term loan modifications to support borrowers during the COVID-19 pandemic. At June 30, 2020, we had granted short-term payment deferrals on $1.58 billion of loans. The loan portfolio continues to be diversified, with the intent to mitigate risk by monitoring concentration in any one sector.

Commercial Real Estate Loans: Commercial real estate 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.

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

Table of Contents

Agriculture Loans: Agricultural lending includes agricultural real estate and production loans and lines of credit within our primary market area. We are committed to our Pacific Northwest communities offering seasonal and longer-term loans and operating lines of credit by lending officers with expertise in the agricultural communities we serve. Typical loan-to-value ratios on term loans can range from 55% to 80% depending upon the type of loan. Operating lines of credit require the borrower to provide a 20% to 25% equity investment. The debt coverage ratio is generally 1.25:1 or better on all term loans.

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 service) 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.

One-to-four Family Residential Real Estate Loans: One-to-four family residential loans, including home equity loans and lines of credit, are secured by properties located within our primary market areas and, typically, have loan-to-value ratios of 80% or lower at origination.

Other Consumer Loans: Consumer loans include automobile loans, boat and recreational vehicle financing, and other 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.

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.

At June 30, 2020, nonperforming assets were $54.5 million, compared to $33.6 million at December 31, 2019. Nonperforming assets increased $20.9 million during the six months ended June 30, 2020, primarily due to a $14.1 million increase in nonaccrual agriculture loans and a $7.4 million increase in nonaccrual commercial real estate loans. For information on OREO, see Note 6 of the Consolidated Financial Statements in “Item 1. Financial Statements (unaudited)” of this report.

Allowance for Credit Losses

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

At June 30, 2020, our ACL was $151.5 million, or 1.55% of total loans (excluding loans held for sale). This compares with an ALLL of $84.0 million, or 0.96% of total loans (excluding loans held for sale) at December 31, 2019 and an ALLL of $80.5 million or 0.93% of total loans (excluding loans held for sale) at June 30, 2019. The increase was primarily the result of COVID-19 and the corresponding downturn in the local, national and world economies as well as increased unemployment rates. The ACL at June 30, 2020 does not include a reserve for the PPP loans as they are fully guaranteed by the SBA.

Liquidity and Sources of Funds

Our primary sources of funds are customer deposits. Additionally, we utilize advances from the FHLB, borrowings from the FRB, sweep repurchase agreements, subordinated debentures assumed in acquisitions and a revolving line of credit 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, meet deposit withdrawals and maturing liabilities, to acquire 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. We have established a branch system to serve our consumer and business depositors. Deposits increased $2.40 billion from December 31, 2019. The addition of PPP loans during the current quarter had a notable impact on our deposits, as our clients deposited these funds into their deposit accounts. In addition, management’s strategy for funding asset growth is to make use of public funds and 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, 2020, brokered deposits, reciprocal money market accounts and other wholesale deposits (excluding public funds) totaled $577.7 million, or 4.4% of total deposits, compared to $329.5 million or 3.1% at year-end 2019. These deposits have varied maturities.

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

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, 2020, we had FHLB advances of $157.4 million compared to $953.5 million at December 31, 2019.

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, 2020 and December 31, 2019, we had deposit customer sweep-related repurchase agreements of $51.5 million and $64.4 million, respectively, which mature on a daily basis.

Subordinated debentures are another source of funding. The Company assumed $35.0 million in aggregate principal amount with its acquisition of Pacific Continental on November 1, 2017. These subordinated debentures, which are unsecured, are callable on June 30, 2021 and have a stated maturity date of June 30, 2026.

The Company has a $15.0 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. At both June 30, 2020 and December 31, 2019, there was no balance associated with this credit facility. 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, 2020.

Management anticipates we will continue to rely on FHLB advances, FRB borrowings, the short-term credit facility and wholesale and retail repurchase agreements in the future. 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 repayments of borrowings, operating and equipment lease payments, off-balance sheet commitments to extend credit and investments in affordable housing partnerships. At June 30, 2020, we had commitments to extend credit of $2.67 billion compared to $2.70 billion at December 31, 2019.

Capital Resources

Shareholders’ equity at June 30, 2020 was $2.28 billion, compared to $2.16 billion at December 31, 2019. Shareholders’ equity was 14% and 15% of total period-end assets at June 30, 2020 and December 31, 2019, respectively.

Regulatory Capital

In July 2013, the federal bank regulators approved the Capital Rules (as discussed in our 2019 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, which were fully phased in as of January 1, 2019. As of June 30, 2020, we and the Bank met all capital adequacy requirements under the Capital Rules.

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, 2020 and December 31, 2019.

As part of its response to the impact of COVID-19, the U.S. federal regulatory agencies issued an interim final rule that provided the option to temporarily delay certain effects of CECL on regulatory capital for two years, followed by a three year transition period. The interim final rule allows bank holding companies and banks to delay for two years 100% of the day one impact of adopting CECL and 25% of the cumulative change in the reported allowance for credit losses since adopting CECL. The Company elected to adopt the interim final rule. As a result, capital ratios and amounts as of June 30, 2020 exclude the impact of the increased allowance for credit losses related to the adoption of CECL.

Table of Contents

The following table presents the capital ratios and the capital conservation buffer, as applicable, for the Company and its banking subsidiary at June 30, 2020 and December 31, 2019:

Stock Repurchase Program

As described in our Annual Report on Form 10-K for the year ended December 31, 2019, 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 share repurchase authorization expired in May of 2020. There were no share repurchases during the three months ended June 30, 2020. The Company repurchased 731 thousand shares of common stock totaling $20.0 million during the six months ended June 30, 2020.

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,

(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 $1.8 million and $2.1 million for the three months ended June 30, 2020 and 2019, respectively, and an addition to net interest income of $3.8 million and $4.2 million for the six months ended June 30, 2020 and 2019, respectively.

(2) Beginning January 2020, incremental accretion income on PCI loans is no longer presented separate from incremental accretion income on other acquired loans. Prior period amounts have been reclassified to conform with current period presentation.

Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Sensitivity

We are exposed to interest rate risk, which is the risk that changes in prevailing interest rates will adversely affect assets, liabilities, capital, income and expenses at different times or in different amounts. Generally, there are four sources of interest rate risk as described below:

Repricing risk—Repricing risk is the risk of adverse consequences from a change in interest rates that arises because of differences in the timing of when those interest rate changes affect an institution’s assets and liabilities.

Basis risk—Basis risk is the risk of adverse consequence resulting from unequal changes in the spread between two or more rates for different instruments with the same maturity.

Yield curve risk—Yield curve risk is the risk of adverse consequence resulting from unequal changes in the spread between two or more rates for different maturities for the same instrument.

Option risk—In banking, option risks are known as borrower options to prepay loans and depositor options to make deposits, withdrawals, and early redemptions. Option risk arises whenever a bank’s products give customers the right, but not the obligation, to alter the quantity or the timing of cash flows. We are also exposed to option risk in callable bonds as the counterparty may call the bonds during a low rate environment resulting in reinvestment of the proceeds at lower yields.

Since our earnings are primarily dependent on our ability to generate net interest income, we actively monitor and manage the effects of adverse changes in interest rates on our results of operations. Management of our interest rate risk is overseen by our board of directors, which is responsible for establishing policies and interest rate limits and approving these policies and interest rate limits annually. These policies include our asset/liability management policy, which provides guidelines for controlling our exposure to interest rate risk. These guidelines direct management to assess the impact of changes in interest rates upon both earnings and capital. These guidelines also establish limits for interest rate risk sensitivity.

We maintain an Asset/Liability Management Committee which is responsible for developing, monitoring and reviewing asset/liability processes, interest rate risk exposures, strategies and tactics. The Asset/Liability Management Committee reports on a regular basis to our board of directors. It is the responsibility of management to execute the approved policies, develop and implement risk management strategies and to report to the board of directors on a regular basis.

Interest Rate Risk Sensitivity

We use a number of measures 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 may not be realized and, as a result, actual results will differ from our projections. In addition, variances in the timing, magnitude and frequency of interest rate changes, overall market conditions including volumes and pricing, and changes in management strategies, among other factors, will also result in variances between the projected and actual results.

Based on the results of the simulation model as of June 30, 2020, we would expect decreases in net interest income of $2.8 million and $13.4 million in year one and year two, respectively, if interest rates gradually decrease from current rates by 100 basis points. We would expect an increase in net interest income of $7.0 million and $38.7 million in year one and year two, respectively, if interest rates gradually increase from current rates by 200 basis points.

The projections are based on the current interest rate environment and we assume our balance sheet remains constant during the next two years. Market interest rates are near historical lows. Loan interest rate indexes such as Prime and LIBOR are also near historical lows. Since we don’t assume negative interest rates, the downward repricing of Prime and LIBOR loans is more limited than during a higher interest rate environment. Our ability to reprice deposits downward is also limited given our low cost of funds.

The increase in low cost deposits during the quarter, particularly the increase in non-interest bearing deposits, also impacted our interest rate sensitivity. Increases in interest rates enhances net interest income since our assets tend to reprice more than our deposits. A shift in our deposit mix to interest-bearing deposits or borrowings would reduce this benefit.

On January 23, 2019, the Company entered into an interest rate collar derivative transaction with a $500.0 million notional value based on one month LIBOR. The Company has designated this as a cash flow hedge. This transaction was entered into to minimize the decrease in net interest income if interest rates decline prior to the maturity date of the collar in February 2024.
