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 three months ended March 31, 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.

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 March 31, 2020 and December 31, 2019, accrued interest receivable for securities was $12.3 million and $13.9 million, respectively. The Company does not measure an allowance for credit losses for accrued interest receivable.

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 months ended March 31, 2020 and 2019.

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:

At March 31, 2020, there were 64 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 March 31, 2020.

At March 31, 2020, there were five 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 March 31, 2020.

Table of Contents

At March 31, 2020, there were 41 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 March 31, 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 March 31, 2020.

At March 31, 2020, there were no U.S. government agency and government-sponsored enterprise securities in an unrealized loss position.

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. At March 31, 2020, the Company owned 95,043 shares of Visa Class B shares which are carried at a zero cost basis.

At March 31, 2020 and December 31, 2019, the Company had 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.

At March 31, 2020 and December 31, 2019, $3.37 billion and $3.24 billion of commercial and residential real estate loans were pledged as collateral on FHLB borrowings and additional borrowing capacity. The Company has also pledged $149.9 million and $151.3 million of commercial loans to the FRB for additional borrowing capacity at March 31, 2020 and December 31, 2019, respectively.

Accrued interest receivable for loans is included in “Interest receivable” on the Company’s Consolidated Balance Sheet and is not reflected in the balances in the table above. At March 31, 2020 and December 31, 2019, accrued interest receivable for loans was $32.3 million and $33.0 million, respectively. The Company does not measure an allowance for credit losses for accrued interest receivable.

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.

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. For the three months ended March 31, 2020, the Company wrote-off $783 thousand and $5 thousand of accrued interest on commercial and consumer loans, respectively, as a reduction to interest income. For the three months ended March 31, 2019, the Company wrote-off $539 thousand and $79 thousand of accrued interest on commercial and consumer loans, respectively, as a reduction to interest income.

Total	4	$	1,235	$	1,235	3	$	833	$	833

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 $812 thousand of additional funds on loans classified as TDR as of March 31, 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 months ended March 31, 2020. During the three months ended March 31, 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.

Modifications in response to COVID-19

The Company began offering short-term loan modifications to assist borrowers during the COVID-19 pandemic. The CARES Act along with a joint agency statement issued by the federal banking agencies provides that short-term modifications made in response to COVID-19 do not need to be accounted for as a TDR. Accordingly, the Company does not account for such loan modifications as TDRs. The Company’s loan modifications allow for the deferral of four months of principal and interest. The deferred interest is due and payable at the end of the deferral period and the deferred principal is due and payable on the maturity date. At March 31, 2020, we had granted short-term payment deferrals on $165.1 million of loans. The program is ongoing and additional loans continue to be granted deferrals.

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 $38.1 million increase in the ACL at March 31, 2020 compared to December 31, 2019 was principally the result of the recent COVID-19 pandemic that has created significant volatility in the local, national and world economies. With the national guidance regarding social distancing and state and county mandates to shelter or stay at home, many large and small businesses have had to close and there has been a dramatic increase in new unemployment claims. As a result, we have increased our reserves for lifetime credit losses as a result of the forecasted economic impact of COVID-19.

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 March 31, 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

During the second quarter of 2019, the Company entered into a $30.0 million short-term credit facility with an unaffiliated bank that matures on May 28, 2020. 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. At March 31, 2020, there was an outstanding balance of $5.0 million and no outstanding balance at 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 March 31, 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 $9.7 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 March 31, 2020 and December 31, 2019 was $475.6 million and $428.6 million, respectively. During both the three month periods ended March 31, 2020 and 2019, there were no mark-to-market gains or losses recorded to “Other” noninterest expense.

Interest rate collar	$	23,423	$	6,268	Interest income	$	940	$	—

The notional amount of the interest rate collar was $500.0 million at March 31, 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 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									29,252
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 $29.3 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.

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 March 31, 2020 and December 31, 2019, the Company’s loan commitments amounted to $2.53 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 $25.7 million at both March 31, 2020 and December 31, 2019. In addition, there were $93 thousand commitments under commercial letters of credit used to facilitate customers’ trade transactions and other off-balance sheet liabilities at March 31, 2020 and there were none at 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.

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:

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.

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.

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at March 31, 2020 and December 31, 2019 by level within the fair value 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 and OREO.

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.

OREO - OREO is real property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO is generally measured based on the property’s fair market value as indicated by an appraisal or a letter of intent to purchase. OREO is initially recorded at the fair value less estimated costs to sell. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses, or in the event of a write-up without previous losses charged to the allowance for credit losses, a credit to earnings is recorded. Management periodically reviews OREO in an effort to ensure the property is recorded at its fair value, net of estimated costs to sell. Any fair value adjustments subsequent to acquisition are charged or credited to earnings.

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:

The losses on collateral dependent loans disclosed above represent the amount of the allowance for credit losses and/or charge-offs during the period applicable to loans held at period end. The amount of the allowance is included in the ACL. The losses on OREO disclosed above represent the write-downs taken at foreclosure that were charged to the ACL as well as subsequent changes in valuation allowances from updated appraisals that were recorded to earnings.

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 months ended March 31, 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 month periods ended March 31, 2020 and 2019:

16.	Subsequent Events

Subsequent to March 31, 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 wrote up its remaining 77,683 Visa Class B restricted shares to a fair value of $13.4 million which was also recorded as a gain, for a total gain of $16.4 million. Based on the existing transfer restriction and uncertainty of covered litigation, the shares were previously carried at a zero cost basis. See Note 3, “Securities” for more information on Visa Class B restricted stock.

In addition to the factors set forth in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this report and the factors set forth in the section titled “Risk Factors” in the Company’s Form 10-K, the following factors, among others, could cause actual results to differ materially from the anticipated results expressed or implied by forward-looking statements:


•	national and global economic conditions could be less favorable than expected or could have a more direct and pronounced effect on us than expected and adversely affect our ability to continue internal growth and maintain the quality of our earning assets;


•	the markets where we operate and make loans could face challenges;


•	the risks presented by the economy, which could adversely affect credit quality, collateral values, including real estate collateral, investment values, liquidity and loan originations and loan portfolio delinquency rates;


•	the efficiencies and enhanced financial and operating performance we expect to realize from investments in personnel, acquisitions, and infrastructure may not be realized;


•	interest rate changes could significantly reduce net interest income and negatively affect asset yields and funding sources;


•	the effect of changes to or discontinuation or replacement of LIBOR;


•	projected business increases following strategic expansion could be lower than expected;


•	changes in the scope and cost of FDIC insurance and other coverages;


•	the impact of acquired loans on our earnings;


•	changes in accounting policies or procedures as may be required by the FASB or other regulatory agencies could materially affect our financial statements and how we report those results, and expectations and preliminary analysis relating to how such changes will affect our financial results could prove incorrect;


•	changes in laws and regulations affecting our businesses, including changes in the enforcement and interpretation of such laws and regulations by applicable governmental and regulatory agencies;


•	competition among financial institutions and nontraditional providers of financial services could increase significantly;


•	continued consolidation in the Northwest financial services industry resulting in the creation of larger financial institutions that may have greater resources could change the competitive landscape;


•	the goodwill we have recorded in connection with acquisitions could become impaired, which may have an adverse impact on our earnings and capital;


•	our ability to identify and address cyber-security risks, including security breaches, “denial of service attacks,” “hacking” and identity theft;


•	any material failure or interruption of our information and communications systems;


•	our ability to keep pace with technological changes;


•	our ability to effectively manage credit risk, interest rate risk, market risk, operational risk, legal risk, liquidity risk and regulatory and compliance risk;


•	failure to maintain effective internal controls over financial reporting or disclosure controls and procedures;


•	the effect of geopolitical instability, including wars, conflicts and terrorist attacks;


•	our profitability measures could be adversely affected if we are unable to effectively manage our capital;


•	natural disasters, including earthquakes, tsunamis, flooding, fires and other unexpected events;


•	the effect of COVID-19 and other infectious illness outbreaks that may arise in the future, which has created significant impacts and uncertainties in U.S. and global markets;


•	changes in governmental policy and regulation, including measures taken in response to economic, business, political and social conditions, including with regard to COVID-19; and


•	the effects of any damage to our reputation resulting from developments related to any of the items identified above.

You should take into account that forward-looking statements speak only as of the date of this report. Given the described uncertainties and risks, we cannot guarantee our future performance or results of operations and you should not place undue reliance on forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required under federal securities laws.

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 began closely monitoring the progress of COVID-19 early and enacted our pandemic plan in January to provide support for our team members and clients. Our initial steps encouraged employees with underlying health concerns or family members at risk to stay home, allowing them to draw from a pool of emergency sick leave dedicated for pandemic related use. Team members with the ability to work remotely were encouraged to do so while branches and offices began following disinfecting protocols and social distancing policies. All non-exempt employees who continue to work on location were included in an additional premium pay program. Our clients have received support through payment deferral programs as well as a variety of options from the SBA including the Paycheck Protection Program, the Economic Injury Disaster Loan and other deferral and automatic debt relief programs. Our participation in the Paycheck Protection Program will increase our loan balances and loan interest income over the period those loans are outstanding. As of April 30, 2020, we had granted short-term payment deferrals on $1.29 billion of loans. 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.

Advanced preparation and early action 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 first quarter of $14.6 million or $0.20 per diluted common share, compared to $45.9 million or $0.63 per diluted common share for the first quarter of 2019. Net interest income for the three months ended March 31, 2020 was $122.4 million, an increase of $1.4 million from the prior year period. The increase was a result of higher interest income on securities and higher average balances of securities. These increases were also partially offset by higher interest expense due to higher average balances of FHLB advances.

The provision for credit losses for the first quarter of 2020 was $41.5 million compared to $1.4 million during the first quarter of 2019. The increase in provision expense for the first quarter of 2020 compared to one year ago was principally the result of the recent COVID-19 pandemic that has created significant volatility in the local, national and world economies.

Noninterest income for the current quarter was $21.2 million, a decrease of $489 thousand from the prior year period. The decrease was primarily due to lower treasury management fees and lower net securities gains partially offset by higher loan revenue during the first quarter of 2020.

Total noninterest expense for the quarter ended March 31, 2020 was $84.3 million, a decrease of $429 thousand from the prior year period. This decrease was primarily driven by lower legal and professional fees, B&O taxes and regulatory premiums partially offset by increases in compensation and employee benefits and other noninterest expense.

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 $2.4 million and $2.2 million for the three months ended March 31, 2020 and 2019, respectively. The incremental accretion income on acquired loans was $1.5 million and $2.0 million for the three months ended March 31, 2020 and 2019, respectively.


(2)	Tax-exempt income is calculated on a tax equivalent basis. The tax equivalent yield adjustment to interest earned on loans was $1.3 million for both the three months ended March 31, 2020 and 2019. The tax equivalent yield adjustment to interest earned on tax exempt securities was $612 thousand and $789 thousand for the three months ended March 31, 2020 and 2019, respectively.

Comparison of current quarter to prior year period

Net interest income for the first quarter of 2020 was $122.4 million, up from $121.0 million for the same quarter in 2019. The increase was a result of higher interest income on securities primarily due to $1.9 million of interest income and discount accretion related to the early payoff of three securities and higher average balances of securities. Interest income from loans also had a positive impact as a result of higher average balances although this increase was more than offset by lower interest income due to lower loan rates. The increase in net interest income was partially offset by higher interest expense due to higher average balances of FHLB advances.

The Company’s net interest margin (tax equivalent) decreased to 4.00% in the first quarter of 2020, from 4.32% for the prior year period. This decrease was driven by lower rates on the loan portfolio and higher average balances of FHLB advances. The Company’s operating net interest margin (tax equivalent)⁽¹⁾ decreased to 4.02% from 4.33% during the first quarter of 2019. The decrease was due to the items previously noted for the decrease in the net interest margin.

(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.

Provision for Credit Losses

Comparison of current quarter to prior year period

Effective January 1, 2020, Columbia adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) and all related amendments. The ACL under ASU 2016-13 utilizes the CECL methodology which estimates the expected loan losses over the contractual life of the loans in the loan portfolio of the Bank. Prior to January 1, 2020, the ALLL incurred loss methodology was used which estimated the amount of loan losses that had been incurred at the balance sheet date. The day 1 adoption of ASU 2016-13 and related amendments, resulted in an increase of $1.6 million in our ACL, an increase of $1.6 million to our 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.

During the first quarter of 2020, the Company recorded a $41.5 million net provision for credit losses, under the CECL methodology, compared to a $1.4 million net provision, under the previous ALLL methodology, during the first quarter of 2019. The increase in provision expense for the first quarter of 2020 compared to one year ago was principally the result of the recent COVID-19 pandemic that has created significant volatility in the local, national and world economies. With the national guidance regarding social distancing and state and county mandates to shelter or stay at home, many large and small businesses have had to close and there has been a dramatic increase in new unemployment claims. As a result, we have increased our reserves for lifetime credit losses as a result of the economic impact of COVID-19. For additional information on the impact and potential impact of COVID-19 on our business, financial condition, liquidity, capital and results of operations, see Item 1A “Risk Factors” of this report.

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 first 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 quarter to prior year period

Noninterest income was $21.2 million for the first quarter of 2020, compared to $21.7 million for the same period in 2019. The decrease was primarily due to lower deposit account and treasury management fees, principally lower treasury management fees, and lower net investment securities gains partially offset by higher loan revenue during the first quarter of 2020.

Comparison of current quarter to prior year period

Noninterest expense was $84.3 million for the first quarter of 2020, a decrease of $429 thousand from $84.7 million for the prior year period. This decrease was primarily driven by lower legal and professional fees, B&O taxes and regulatory premiums which decreased by $2.5 million, $1.3 million and $950 thousand, respectively. These decreases were partially offset by increases of $2.8 million in compensation and employee benefits expense and $1.1 million in other noninterest expense. The decrease in professional fees was due to lower fees on reciprocal money market accounts as well as lower expenses related to corporate initiatives. B&O tax expense benefited from a refund received in the current quarter for a prior year. Regulatory premiums decreased due to the utilization of $967 thousand of our FDIC Small Bank Assessment Credit. The remaining balance of our credit is $283 thousand but can only be applied towards our future FDIC deposit insurance expense if the fund exceeds its minimum reserve ratio. The increase in compensation and employee benefits was driven by increases in salary expense and incentive and commissions expense. Other noninterest expense increased due to a higher provision for off-balance sheet reserves.

Income Taxes

We recorded an income tax provision of $3.2 million for the first quarter of 2020, compared to a provision of $10.8 million for the same period in 2019, with effective tax rates of 18% and 19% for the first quarter of 2020 and 2019, respectively. 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 $14.04 billion at March 31, 2020, a decrease of $41.0 million from December 31, 2019. Cash and cash equivalents decreased $31.9 million. Loans increased $189.9 million during the first quarter of 2020, which was primarily the result of new loan production and increased seasonal line utilization, partially offset by payments. Debt securities available for sale were $3.55 billion at March 31, 2020, a decrease of $193.0 million from December 31, 2019. Total liabilities were $11.82 billion as of March 31, 2020, a decrease of $94.7 million from December 31, 2019. The decline was primarily due to a decrease in FHLB advances partially offset by an increase in interest-bearing deposits, specifically public funds, excluding certificates of deposit.

Investment Securities

At March 31, 2020, the Company’s investment portfolio primarily consisted of debt securities available for sale totaling $3.55 billion compared to $3.75 billion at December 31, 2019. The decrease in the debt securities portfolio from year-end is due to $328.5 million in maturities, repayments and sales and $5.6 million in premium amortization offset by $103.6 million in net unrealized gain and $37.5 million in purchases. The average duration of our debt securities investment portfolio was approximately 4 years and 9 months at March 31, 2020. This duration takes into account calls, where appropriate, and consensus prepayment speeds.

Table of Contents

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.

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 through an allowance and the non-credit-related impairment is recognized in accumulated other comprehensive income.

At March 31, 2020, the market value of debt securities available for sale had a net unrealized gain of $146.6 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 three months ended March 31, 2020. At March 31, 2020, the Company had $136.1 million of debt securities available for sale with gross unrealized losses of $1.8 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.

Table of Contents

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.

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.

Table of Contents

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 areas. Management expects a continued focus within its commercial lending products and to emphasize, in particular, relationship banking with businesses and business owners.

Agriculture Loans: Agricultural lending includes agricultural real estate and production loans and lines of credit within our primary market areas. 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 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.

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.

Nonperforming assets increased $14.5 million during the three months ended March 31, 2020, primarily due to $10.1 million increase in nonaccrual agriculture loans and a $3.5 million increase in nonaccrual commercial business 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 March 31, 2020, our ACL was $122.1 million, or 1.37% 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 $83.3 million or 0.98% of total loans (excluding loans held for sale) at March 31, 2019.

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. 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 March 31, 2020, brokered deposits, reciprocal money market accounts and other wholesale deposits (excluding public funds) totaled $407.4 million, or 3.8% 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:



	March 31, 2020					December 31, 2019
	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 March 31, 2020, we had FHLB and FRB borrowings of $712.5 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 March 31, 2020 and December 31, 2019, we had deposit customer sweep-related repurchase agreements of $29.3 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.

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. At March 31, 2020, we had a balance of $5.0 million associated with this credit facility and no balance at 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 March 31, 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 March 31, 2020, we had commitments to extend credit of $2.56 billion compared to $2.70 billion at December 31, 2019.

Capital Resources

Shareholders’ equity at March 31, 2020 was $2.21 billion, compared to $2.16 billion at December 31, 2019. Shareholders’ equity was 16% and 15% of total period-end assets at March 31, 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 March 31, 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 March 31, 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 March 31, 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 March 31, 2020 and December 31, 2019:



	Company				Columbia Bank
	March 31, 2020		December 31, 2019		March 31, 2020		December 31, 2019

Capital conservation buffer	5.42	%	5.60	%	5.41	%	5.29	%

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 Company may purchase the shares from time to time in the open market, in private transactions, by direct or derivative purchases or other 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. The Company repurchased 731 thousand shares of common stock totaling $20.0 million for the three months ended March 31, 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 March 31,
	2020			2019
	(dollars in thousands)
Operating net interest margin non-GAAP reconciliation:
Net interest income (tax equivalent) (1)	$	124,333		$	123,110
Adjustments to arrive at operating net interest income (tax equivalent):
Incremental accretion income on acquired loans (2)	(1,491		)	(2,035		)
Premium amortization on acquired securities	1,127			1,779
Interest reversals on nonaccrual loans	788			626
Operating net interest income (tax equivalent) (1)	$	124,757		$	123,480
Average interest earning assets	$	12,487,550		$	11,561,627
Net interest margin (tax equivalent) (1)	4.00		%	4.32		%
Operating net interest margin (tax equivalent) (1)	4.02		%	4.33		%

__________

(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 $1.9 million and $2.1 million for the three months ended March 31, 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

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 March 31, 2020, 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, 2019. For additional information, refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2019 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 Control Over Financial Reporting

Due to implementation of CECL issued by the FASB, the Bank has made updates to its internal control over financial reporting. Controls around ALLL were replaced with CECL controls, including processes and control owners. With the exception of these changes, 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 control over financial reporting.

PART II - OTHER INFORMATION


Item 1.	LEGAL PROCEEDINGS

The Company and its subsidiaries are party to routine litigation arising in the ordinary course of business. Management believes that, based on information currently known to it, any liabilities arising from such litigation will not have a material adverse impact on the Company’s financial conditions, results of operations or cash flows.

Item 1A. RISK FACTORS

Refer to Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 for a discussion of risk factors relating to the Company’s business. The Company believes that there has been no material change in its risk factors as previously disclosed in the Company’s Form 10-K, except for the addition of the following risk factor:

The COVID-19 pandemic has impacted our business, and the ultimate impact on our business and financial results will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and dramatically increased unemployment levels. In addition, the pandemic has resulted in temporary closures of many businesses and the institution of social distancing and sheltering in place requirements in many states and communities. As a result, the demand for our products and services has been and may continue to be significantly impacted. Furthermore, as discussed elsewhere in this report, the pandemic has influenced the recognition of credit losses in our loan portfolios and is expected to do so, particularly as businesses remain closed and as more customers are expected to draw on their lines of credit or seek additional loans to help finance their businesses. Similarly, because of changing economic and market conditions affecting issuers, we may be required to recognize provisions for credit losses in future periods on the securities we hold as well as reductions in other comprehensive income. Our business operations may also be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic, and we have already temporarily closed certain of our branches. In response to the pandemic, we are also offering payment deferrals and other expanded assistance for mortgage, small business and personal lending customers. We also face an increased risk of litigation and governmental and regulatory scrutiny as a result of the effects of COVID-19 on market and economic conditions and actions governmental authorities take in response to those conditions. The length of the pandemic and the efficacy of the extraordinary measures being put in place to address it are unknown. Until the pandemic subsides, we expect continued draws on lines of credit, reduced revenues and increased client defaults. Even after the pandemic subsides, the U.S. economy may experience a recession which may be prolonged, which could materially and adversely affect our business, financial condition, liquidity, capital and results of operations, it may also have the effect of heightening many of the other risks described in the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 and any subsequent Quarterly Reports on Form 10-Q. The extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

In addition, the Federal Reserve has taken direct actions that adversely impact interest income. On February 28, 2020, the Board of Governors of the Federal Reserve stated that it was closely monitoring COVID-19 developments and their effects on the economic outlook, and has taken direct actions that adversely impact interest income. On March 3, 2020, the Federal Reserve reduced the target federal funds rate by 50 basis points to 1.00% to 1.25%. The Federal Reserve also announced it was purchasing Treasury bills into the second quarter of 2020, conducting overnight repurchase agreement operations at least through April 2020, and will continue to reinvest amounts of principal received by the Federal Reserve on its portfolio of treasury and agency debt and mortgage-backed securities. Lastly, the Federal Reserve also reduced the interest it pays on excess reserves from 1.60% to 1.10%. On March 15, 2020, the Federal Reserve further reduced the target federal funds rate by 100 basis points to 0% to 0.25%. The Federal Reserve also announced that it would further increase its holding of Treasury securities and agency mortgage-backed securities. We expect that such reductions in interest rates will adversely affect our net interest income and margins and our profitability.
