Supervision and Regulation
The following discussion provides an overview of certain elements of the extensive regulatory framework applicable to the Company and Columbia State Bank, which operates under the name Columbia Bank in Washington, Oregon, Idaho and Idaho.California. This regulatory framework is primarily designed for the protection of depositors, customers, federal deposit insurance funds and the banking system as a whole, rather than specifically for the protection of shareholders or non-depository creditors. Due to the breadth and growth of this regulatory framework, our costs of compliance continue to increase in order to monitor and satisfy these requirements.

To the extent that this section describes statutory and regulatory provisions, it is qualified by reference to those provisions. These statutes and regulations, as well as related policies, are subject to change by Congress, state legislatures and federal and state regulators. Changes in statutes, regulations or regulatory policies applicable to us, including the interpretation or implementation thereof, cannot be predicted, but may have a material effect on our business, financial condition, or results of operations. Our continued efforts to monitor and comply with new regulatory requirements and developments add to the complexity and cost of our business.

Federal and State Bank Holding Company Regulation
General.  The Company is a bank holding company as defined in the BHCA, and is therefore subject to regulation, supervision and examination by the Federal Reserve. In general, the BHCA limits the business of bank holding companies to owning or controlling banks and engaging in other activities closely related to banking. The Company must file reports with and provide the Federal Reserve such additional information as it may require. Under the Financial Services Modernization Act of 1999, a bank holding company may apply to the Federal Reserve to become a financial holding company, and thereby engage (directly or through a subsidiary) in certain expanded activities deemed financial in nature, such as securities and insurance underwriting. AsWhile not a financial holding company as of the date of this report, we have not elected to be treated as a financial holding company.company upon consummation of our proposed merger with Umpqua. To maintain its status as a financial holding company, a bank holding company (and all of its depository institution subsidiaries) must each remain “well capitalized” and “well managed”. If a bank holding company fails to meet these regulatory standards, the Federal Reserve could place limitations on its ability to conduct the broader financial activities permissible for financial holding companies or impose limitations or conditions on the conduct or activities of the bank holding company or its affiliates. If the deficiencies persisted, the Federal Reserve could order the bank holding company to divest any subsidiary bank or to cease engaging in any activities permissible for financial holding companies that are not permissible for bank holding companies.
Holding Company Bank Ownership. The BHCA requires every bank holding company to obtain the prior approval of the Federal Reserve before (i) acquiring, directly or indirectly, ownership or control of any voting shares of another bank or bank holding company if, after such acquisition, it would own or control more than 5% of such shares; (ii) acquiring all or substantially all of the assets of another bank or bank holding company; or (iii) merging or consolidating with another bank holding company. In addition, under the Bank Merger Act of 1960, as amended, the prior approval of the FDIC is required for the Bank to merge with another bank or purchase all or substantially all of the assets or assume any of the deposits of another FDIC-insured depository institution. In reviewing applications seeking approval of merger and acquisition transactions, bank regulators consider, among other things, the competitive effect and public benefits of the transactions, the capital position and managerial resources of the combined organization, the risks to the stability of the U.S. banking or financial system, the applicant’s performance record under the CRA, the applicant’s compliance with other laws, including fair housing and other consumer protection laws, and the effectiveness of all organizations involved in combating money laundering activities. In addition, failure to implement or maintain adequate compliance programs could cause bank regulators not to approve an acquisition where regulatory approval is required or to prohibit an acquisition even if approval is not required.
In July 2021, the Biden administration issued an executive order on competition, which included provisions relating to bank mergers. These provisions “encourage” the Department of Justice and the federal banking regulators to update guidelines on banking mergers and to provide more scrutiny of bank mergers. We are unable to predict what impact the executive order will have on the timing of or ability to obtain regulatory approvals of future mergers.
Holding Company Control of Nonbanks. With some exceptions, the BHCA also prohibits a bank holding company from acquiring or retaining direct or indirect ownership or control of more than 5% of the voting shares of any company which is not a bank or bank holding company, or from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries. The principal exceptions to these prohibitions involve certain non-bank activities that, by statute or by Federal Reserve regulation or order, have been identified as activities so closely related to the business of banking as to be a proper incident thereto, such as Columbia Trust.
8

Tying Arrangements. We are prohibited from engaging in certain tie-in arrangements in connection with any extension of credit, sale or lease of property or furnishing of services. For example, with certain exceptions, neither the Company nor its subsidiaries may condition an extension of credit to a customer on either (i) a requirement that the customer obtain additional services provided by us; or (ii) an agreement by the customer to refrain from obtaining other services from a competitor.
Support of Subsidiary Banks. Under Federal Reserve policy and federal law, the Company is required to act as a source of financial and managerial strength to Columbia Bank, including at times when we may not be in a financial position to provide such resources, and it may not be in our, or our shareholders’, best interests to do so. This means that the Company is required to commit resources, as necessary, to support Columbia Bank. Any capital loans a bank holding companythe Company makes to its subsidiary banksColumbia Bank are subordinate to deposits and to certain other indebtedness of those subsidiary banks.Columbia Bank.
State Law Restrictions. As a Washington corporation, the Company is subject to certain limitations and restrictions under applicable Washington corporate law. For example, state law restrictions in Washington include limitations and restrictions relating to indemnification of directors, distributions to shareholders, transactions involving directors, officers or interested shareholders, maintenance of books, records and minutes, and observance of certain corporate formalities.
Federal and State Regulation of Columbia Bank
General. The deposits of Columbia Bank, a Washington charteredstate-chartered commercial bank with branches in Washington, Oregon, Idaho and Idaho,California, are insured by the FDIC. As a result, Columbia Bank is subject to supervision and regulation by the Washington Department of Financial Institutions’ Division of Banks and the FDIC. In connection with our proposed merger with Umpqua, it is proposed that the Bank will merge with and into Umpqua Bank, following which our bank subsidiary will be subject to supervision and regulation by the Oregon Department of Consumer and Business Services Division of Financial Regulation. These agencies have the authority to prohibit banks from engaging in what they believe constitute unsafe or unsound banking practices. Furthermore, under the FDIA, insurance of deposits may be terminated by the FDIC if the FDIC finds that the insured depository institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. With respect to branches of Columbia Bank in Oregon, Idaho and Idaho,California, the Bank is also subject to certain laws and regulations governing its activities in those states.

Consumer Protection. The Bank is subject to a variety of federal and state consumer protection laws and regulations that govern its relationship with consumers, including laws and regulations that impose certain disclosure requirements and regulate the manner in which we take deposits, make and collect loans, and provide other services. Failure to comply with these laws and regulations may subject the Bank to various penalties, including but not limited to, enforcement actions, injunctions, fines, civil monetary penalties, criminal penalties, punitive damages, and the loss of certain contractual rights. As an insured depository institution with assets of $10 billion or more, the CFPB has primary enforcement and exclusive supervision authority for federal consumer financial laws over the Bank. This includes the right to obtain information about the Bank’s activities and compliance systems and procedures and to detect and assess risks to consumers and markets. The CFPB engages in several activities, including (i) investigating consumer complaints about credit cards and mortgages, (ii) launching supervisory programs, (iii) conducting research for and developing mandatory financial product disclosures, and (iv) engaging in consumer financial protection rulemaking. Columbia Bank has established a compliance management system designed to ensure consumer protection.
Community Reinvestment. The CRA requires that, in connection with examinations of financial institutions within their jurisdiction, the Federal Reserve, OCC or the FDIC evaluate the record of the financial institution in meeting the credit needs of its local communities, including lowlow- and moderate-income neighborhoods, consistent with the safe and sound operation of the institution. A bank’s community reinvestment record is also considered by the applicable banking agencies in evaluating mergers, acquisitions and applications to open a branch or facility. The Bank’s failure to comply with the CRA could, among other things, result in the denial or delay of such transactions. The Bank received a rating of “satisfactory”“outstanding” in its most recently completed CRA examination. In December 2019,examination (for the period of April 1, 2017 through May 4, 2020). On May 5, 2022, the Federal Reserve, FDIC and the OCC and FDICjointly issued a notice of proposed rulemaking intendedproposing revisions to (i) clarify whichthe agencies’ CRA regulations, including with respect to the delineation of assessment areas, the overall evaluation framework and performance standards and metrics, the definition of community development activities, qualify for CRA credit; (ii) update where activities count for CRA credit; (iii) create a more transparent and objective method for measuring CRA performance; and (iv) provide for more transparent, consistent, and timely CRA-related data collection recordkeeping, and reporting. The Federal Reserve has not joinedproposed rule would adjust CRA evaluations based on bank size and type, with many of the proposed rulemaking.changes applying only to banks with over $2 billion in assets and several applying only to banks with over $10 billion in assets, such as Columbia Bank. Management will continue to evaluate any changes to CRA regulations.

Anti-Money Laundering, Anti-Terrorism and Anti-Terrorism.Sanctions. The BSA requires all financial institutions, including banks, to, among other things, establish a risk-based system of internal controls reasonably designed to prevent money laundering and the financing of terrorism. It includes a variety of recordkeeping and reporting requirements (such as cash and suspicious activity reporting) as well as due diligence/know-your-customer documentation requirements.
The Patriot Act further augments and strengthens the requirements set forth in the BSA. The Patriot Act, in relevant part, (i) prohibits banks from providing correspondent accounts directly to foreign shell banks; (ii) imposes due diligence requirements on banks opening or holding accounts for foreign financial institutions or wealthy foreign individuals; (iii) requires financial institutions to establish an anti-money-laundering compliance program; and (iv) eliminates civil liability for persons who file suspicious activity reports. The Patriot Act also includes provisions providing the government with power to investigate terrorism, including expanded government access to bank account records.
Columbia Bank is also subject to regulation under the International Emergency Economic Powers Act and the Trading with the Enemy Act, as administered by the United States Treasury Department’s Office of Foreign Assets Control (“Sanctions Laws”). The Sanctions Laws are intended to restrict transactions with persons, companies, or foreign governments sanctions by U.S. authorities. An institution that fails to meet these standards may be subject to regulatory sanctions, including limitations on growth. Columbia Bank has established compliance programs designed to comply with the BSA, and the Patriot Act.Act and applicable Sanctions Laws.
Transactions with Affiliates; Insider Credit Transactions. Transactions between the Bank and its subsidiaries, on the one hand, and the Company or any other subsidiary, on the other hand, are regulated under federal banking law. The Federal Reserve Act imposes quantitative and qualitative requirements and collateral requirements on covered transactions by the Bank with, or for the benefit of, its affiliates. In addition, subsidiary banks of a bank holding company are subject to restrictions on extensions of credit to the holding company or its subsidiaries, on investments in securities of the holding company or its subsidiaries and on the use of their securities as collateral for loans to any borrower. These regulations and restrictions may limit the Company’s ability to obtain funds from Columbia Bank for its cash needs, including funds for payment of dividends, interest and operational expenses.
Banks are also subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to executive officers, directors, principal shareholders or any related interests of such persons. Extensions of credit (i) must be made on substantially the same terms, including interest rates and collateral, and follow credit underwriting procedures that are at least as stringent as those prevailing at the time for comparable transactions with persons not related to the lending bank; and (ii) must not involve more than the normal risk of repayment or present other unfavorable features. Banks are also subject to certain lending limits and restrictions on overdrafts to insiders. A violation of these restrictions may result in the assessment of substantial civil monetary penalties, regulatory enforcement actions, and other regulatory sanctions. The Columbia Bank board has established controls to ensure compliance with regulatory expectations around affiliated transactions.

Regulation of Management. Federal law (i) sets forth circumstances under which officers or directors of a bank may be removed by the institution’s federal supervisory agency; (ii) places constraints on lending by a bank to its executive officers, directors, principal shareholders, and their related interests; and (iii) generally prohibits management personnel of a bank from serving as directors or in other management positions of another financial institution whose assets exceed a specified amount or which has an office within a specified geographic area.
Safety and Soundness Standards. Certain non-capital safety and soundness standards are also imposed upon banks. These standards cover internal controls, information systems and internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, such other operational and managerial standards as the agency determines to be appropriate, and standards for asset quality, earnings and stock valuation. An institution that fails to meet these standards may be subject to regulatory sanctions, including limitations on growth. Columbia Bank has established policies and risk management activities designed to ensure the safety and soundness of the Bank.
Interstate Banking and Branching
The Interstate Act together with the Dodd-Frank Act relaxed prior interstate branching restrictions under federal law by permitting, subject to regulatory approval, state and federally chartered commercial banks to establish branches in states where the laws permit banks chartered in such states to establish branches. The Interstate Act requires regulators to consult with community organizations before permitting an interstate institution to close a branch in a low-income area. Federal banking agency regulations prohibit banks from using their interstate branches primarily for deposit production and the federal banking agencies have implemented a loan-to-deposit ratio screen to ensure compliance with this prohibition.

Dividends
Columbia is a legal entity separate and distinct from the Bank and its other subsidiaries. As a bank holding company, Columbia is subject to certain restrictions on its ability to pay dividends under applicable banking laws and regulations. Federal bank regulators are authorized to determine under certain circumstances relating to the financial condition of a bank holding company or a bank that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof. In particular, federal bank regulators have stated that paying dividends that deplete a banking organization’s capital base to an inadequate level would be an unsafe and unsound banking practice and that banking organizations should generally pay dividends only out of current operating earnings. In addition, in the current financial and economic environment, the Federal Reserve has indicated that bank holding companies should carefully review their dividend policy and has discouraged payment ratios that are at maximum allowable levels unless both asset quality and capital are very strong. Federal Reserve policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company’s capital structure. A significant portion of our income comes from dividends from the Bank, which is also the primary source of our liquidity. In addition to the restrictions discussed above, the Bank is subject to limitations under Washington law regarding the level of dividends that it may pay to the Company.Company (if the proposed merger with Umpqua is completed, the Bank, following its merger with and into Umpqua Bank, will be subject to Oregon limitations instead). Washington law limits a bank’s ability to pay dividends that are greater than the bank’s retained earnings without approval of the applicable banking agency.agency (under Oregon law, a bank may not pay dividends greater than the bank’s unreserved retained earnings, deducting therefrom, to the extent not already charged against earnings or reflected in a reserve, all bad debts, which are debts on which interest is past due and unpaid for at least six months, unless the debt is fully secured and in the process of collection; all other assets charged-off as required by Oregon bank regulators or a state or federal examiner; and all accrued expenses, interest and taxes of the institution).
Regulatory Capital Requirements
The Federal Reserve monitors the capital adequacy of the Company on a consolidated basis, and the FDIC and the Washington Department of Financial Institutions’ Division of Banks monitor, and if the proposed merger with Umpqua is completed, the Oregon Department of Consumer and Business Services Division of Financial Regulation will monitor the capital adequacy of the Bank. The Capital Rules are based on the December 2010 final capital framework for strengthening international capital standards, known as Basel III, of the Basel Committee. As of December 31, 2019,2022, we and the Bank met all capital adequacy requirements under the Capital Rules, as described below.
The Capital Rules, among other things (i) include a capital measure called CET1, (ii) specify that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements and (iii) define CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital.
Under the Capital Rules, the minimum capital ratios are (i) 4.5% CET1 to risk-weighted assets, (ii) 6% Tier 1 capital (that is, CET1 plus Additional Tier 1 capital) to risk-weighted assets and (iii) 8% total capital (that is, Tier 1 capital plus Tier 2 capital) to risk-weighted assets.
The Capital Rules also require an institution to establish a capital conservation buffer of CET1 in an amount above the minimum risk-based capital requirements for “adequately capitalized” institutions equal to 2.5% of total risk-weighted assets. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall and the institution’s “eligible retained income” (that is, four quarter trailingthe greater of (i) net income for the preceding four quarters, net of distributions and associated tax effects not reflected in net income)income and (ii) average net income over the preceding four quarters).

The Capital Rules provide for a number of deductions from and adjustments to CET1. These include, for example, the requirement that mortgage servicing rights, certain deferred tax assets and significant investments in non-consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such categories in the aggregate exceed 15% of CET1. The Capital Rules also generally preclude certain hybrid securities, such as trust preferred securities, from being counted as Tier 1 capital for most bank holding companies. However, bank holding companies such as the Company who had less than $15 billion in assets as of December 31, 2009 (and who continue to have less than $15 billion in assets) are permitted to include trust preferred securities issued prior to May 19, 2010 as Additional Tier 1 capital under the Capital Rules.
In addition, the Company and the Bank are subject to the final rule adopted by the Federal Reserve, OCC and FDIC in July 2019 relating to simplifications of the capital rules applicable to non-advanced approaches banking organizations. These rules will bebecame effective for the Company on April 1, 2020 and provide for simplified capital requirements relating to the threshold deductions for mortgage servicing assets, deferred tax assets arising from temporary differences that a banking organization could not realize through net operating loss carry backs, and investments in the capital of unconsolidated financial institutions, as well as the inclusion of minority interests in regulatory capital.

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III post-crisis regulatory reforms. The standards are commonly referred to as “Basel IV.” Among other things, these standards revise the Basel Committee’s standardized approach for credit risk (including by recalibrating risk weights and introducing new capital requirements for certain “unconditionally cancellable commitments,” such as home equity lines of credit) and providesprovide a new standardized approach for operational risk capital. Under theThe Basel framework contemplates that these standards will generally be effective on January 1, 2022,2023, with an aggregate output floor phasing in through January 1, 2027.2028. The federal bank regulators have not yet proposed rules implementing these standards. In July 2020, the Basel Committee finalized further revisions to the framework for credit valuation adjustment risk, which are intended to align that framework with the market risk framework. Under the current U.S. capital rules, operational risk capital requirements and a capital floor apply only to advanced approachapproaches institutions. The impact of Basel IV on the Company and the Bank will depend on the manner in which it is implemented by the federal bank regulators.
The Bank is also subject to the prompt corrective action regulations pursuant to Section 38 of the FDIA. See “Prompt Corrective Action Framework.”
Prompt Corrective Action Framework
The FDIA requires the federal bank regulators to take prompt corrective action in respect of depository institutions that fail to meet specified capital requirements. The FDIA establishes five capital categories (“well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized”), and the federal bank regulators are required to take certain mandatory supervisory actions, and are authorized to take other discretionary actions, with respect to institutions that are undercapitalized, significantly undercapitalized or critically undercapitalized. The severity of these mandatory and discretionary supervisory actions depends upon the capital category in which the institution is placed. Generally, subject to a narrow exception, the FDIA requires the regulator to appoint a receiver or conservator for an institution that is critically undercapitalized.
Under the rules currently in effect, the following table presents the requirements for an insured depository institution to be classified as well-capitalized or adequately capitalized:
“Well-capitalized”“Adequately capitalized”
Total capital ratio of at least 10%,Total capital ratio of at least 8%,
Tier 1 capital ratio of at least 8%,Tier 1 capital ratio of at least 6%
CET1 ratio of at least 6.5%CET1 ratio of at least 4.5%, and
Tier 1 leverage ratio of at least 5%, andTier 1 leverage ratio of at least 4%.
Not subject to any order or written directive requiring a specific capital level.
An institution may be downgraded to, or deemed to be in, a capital category that is lower than indicated by its capital ratios if it is determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect to certain matters. A bank’s capital category is determined solely for the purpose of applying prompt corrective action regulations, and the capital category may not constitute an accurate representation of the bank’s overall financial condition or prospects for other purposes.
As of December 31, 2019,2022, we and the Bank met the capital requirements to be well-capitalized with CET1 capital ratios of 12.45%12.87% and 12.46%12.93%, respectively, Tier 1 capital ratios of 12.45%12.87% and 12.46%12.93%, respectively, total capital ratios of 13.60%13.98% and 13.29%13.97%, respectively, and Tier 1 leverage ratios of 10.17%9.34% and 10.22%9.47%, respectively.

12

An institution that is categorized as undercapitalized, significantly undercapitalized or critically undercapitalized is required to submit an acceptable capital restoration plan to its appropriate federal bank regulator. Under the FDIA, in order for the capital restoration plan to be accepted by the appropriate federal banking agency, a bank holding company must guarantee that a subsidiary depository institution will comply with its capital restoration plan, subject to certain limitations. The bank holding company must also provide appropriate assurances of performance. The obligation of a controlling bank holding company under the FDIA to fund a capital restoration plan is limited to the lesser of 5% of an undercapitalized subsidiary’s assets or the amount required to meet regulatory capital requirements. An undercapitalized institution is also generally prohibited from increasing its average total assets, making acquisitions and capital distributions, establishing any branches or engaging in any new line of business, except in accordance with an accepted capital restoration plan or with the approval of the FDIC. Institutions that are undercapitalized or significantly undercapitalized and either fail to submit an acceptable capital restoration plan or fail to implement an approved capital restoration plan may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become adequately capitalized, requirements to reduce total assets and cessation of receipt of deposits from correspondent banks. Critically undercapitalized depository institutions failing to submit or implement an acceptable capital restoration plan are subject to appointment of a receiver or conservator.
Brokered Deposits
The FDIA prohibits an insured depository institution from accepting brokered deposits or offering interest rates on any deposits significantly higher than the prevailing rate in the bank’s normal market area or nationally (depending upon where the deposits are solicited), unless it is well-capitalized or is adequately capitalized and receives a waiver from the FDIC. A depository institution that is adequately capitalized and accepts brokered deposits under a waiver from the FDIC may not pay an interest rate on any deposit in excess of 75 basis points over certain prevailing market rates.
On December 12, 2019, the FDIC issued a notice of proposed rulemaking intended to modernize its brokered deposit regulations in light of modern deposit-taking methods. The impact on the Company and the Bank will depend on the final form of the proposed rule, which the Company is unable to predict.
Regulatory Oversight and Examination
The Federal Reserve conducts periodic inspections of bank holding companies. The supervisory objectives of the inspection program are to ascertain whether the financial strength of the bank holding company is being maintained on an ongoing basis and to determine the effects or consequences of transactions between a holding company or its non-banking subsidiaries and its subsidiary banks.
Banks are subject to periodic examinations by their primary regulators. Bank examinations have evolved from reliance on transaction testing in assessing a bank’s condition to a risk-focused approach. These examinations are extensive and cover the entire breadth of operations of the bank. Generally, FDIC safety and soundness examinations for a bank of our size are completed on an annual basis through the execution of a quarterly focal review process. The FDIC and state bank regulatory agencies complete these examinations on a combined schedule.
The CFPB has primary examination and enforcement authority over institutions with assets of $10 billion or more, including the Bank, with respect to various federal consumer protection laws, and we are subject to continued examination by the FDIC on certain consumer regulations. State authorities are also responsible for monitoring our compliance with all state consumer laws.
The frequency of consumer compliance and CRA examinations is linked to the size of the institution and its compliance and CRA ratings at its most recent examinations. However, the examination authority of the Federal Reserve and the FDIC allows them to examine supervised banks as frequently as deemed necessary based on the condition of the bank or as a result of certain triggering events.
Financial Privacy
Under the Gramm-Leach-Bliley Act of 1999, as amended, a financial institution may not disclose non-public personal information about a consumer to unaffiliated third-parties unless the institution satisfies various disclosure requirements and the consumer has not elected to opt out of the information sharing. The financial institution must provide its customers with a notice of its privacy policies and practices. The Federal Reserve, the FDIC, and other financial regulatory agencies issued regulations implementing notice requirements and restrictions on a financial institution's ability to disclose non-public personal information about consumers to unaffiliated third-parties.
13

In addition, privacy and data protection are areas of increasing state legislative focus, and several states have recently enacted consumer privacy laws that impose significant compliance obligations with respect to personal information. For example, the Company is subject to the CCPA and its implementing regulations. The CCPA gives consumers the right to request disclosure of information collected about them, and whether that information has been sold or shared with others, the right to request deletion of personal information (subject to certain exceptions), the right to opt out of the sale of the consumer’s personal information, and the right not to be discriminated against for exercising these rights. The CCPA contains several exemptions, including an exemption applicable to information that is collected, processed, sold or disclosed pursuant to the Gramm-Leach-Bliley Act of 1999, as amended. In November 2020, voters in the CPRA, a ballot measure that amends and supplements the CCPA by, among other things, expanding certain rights relating to personal information and its use, collection, and disclosure by covered businesses. The key provisions of the CPRA became effective on January 1, 2023, with civil and administrative enforcement of the CPRA beginning July 1, 2023. Similar laws may in the future be adopted by other states where the Company does business. The Company has made and will make operational adjustments in accordance with the requirements of the CCPA and other state privacy laws. Furthermore, privacy and data protection areas are expected to receive further attention at the federal level. The potential effects of state or federal privacy and data protection laws on the Company’s business cannot be determined at this time, and will depend both on whether such laws are adopted by states in which the Company does business and/or at the federal level and the requirements imposed by any such laws.
Cybersecurity
The federal banking agencies have established certain expectations with respect to an institution's information security and cybersecurity programs, with an increasing focus on risk management, processes related to information technology and operational resiliency, and the use of third parties in the provision of financial services. In October 2016, the federal banking agencies jointly issued an advance notice of proposed rulemaking on enhanced cybersecurity risk-management and resilience standards that would address five categories of cyber standards which include (i) cyber risk governance, (ii) cyber risk management, (iii) internal dependency management, (iv) external dependency management, and (v) incident response, cyber resilience, and situational awareness. As proposed, these enhanced standards would apply only to depository institutions and depository institution holding companies with total consolidated assets of $50 billion or more; however, it is possible that if these enhanced standards are implemented, even if the $50 billion threshold is increased, the Federal Reserve will consider them in connection with the examination and supervision of banks below the $50 billion threshold. The federal banking agencies have not yet taken further action on these proposed standards. If we complete the pending merger with Umpqua, we will likely have greater than $50 billion in total consolidated assets and, as a result, would be subject to these enhanced cybersecurity risk-management and resilience standards.
State regulators have also been increasingly active in implementing privacy and cybersecurity standards and regulations. Recently, several states have adopted regulations requiring certain financial institutions to implement cybersecurity programs with detailed requirements, including data encryption requirements. Many states have also recently implemented or modified their data breach notification and data privacy requirements. We expect this trend of state-level cybersecurity regulation to continue, and are continually monitoring developments in the states in which the Company operates.
In February 2018, the SEC published interpretive guidance to assist public companies in preparing disclosures about cybersecurity risks and incidents. These SEC guidelines, and any other regulatory guidance, are in addition to notification and disclosure requirements under state and federal banking law and regulations. In addition, in March 2022, the SEC proposed new rules that would require reporting on Form 8-K of material cybersecurity incidents.
In November 2021, the U.S. federal bank regulatory agencies adopted a rule regarding notification requirements for banking organizations related to significant computer security incidents. Under the final rule, a bank holding company, such as the Company, and an FDIC-supervised insured depository institution, such as the Bank, are required to notify the Federal Reserve or FDIC, respectively, within 36 hours of incidents that have materially disrupted or degraded, or are reasonably likely to materially disrupt or degrade, the banking organization’s ability to deliver services to a material portion of its customer base, jeopardize the viability of key operations of the banking organization, or impact the stability of the financial sector.
Corporate Governance and Accounting
SOX addresses, among other things, corporate governance, auditing and accounting, enhanced and timely disclosure of corporate information, and penalties for non-compliance. Generally, SOX (i) requires CEOs and CFOs to certify the accuracy of periodic reports filed with the SEC; (ii) imposes specific and enhanced corporate disclosure requirements; (iii) accelerates the time frame for reporting of insider transactions and periodic disclosures by public companies; (iv) requires companies to adopt and disclose information about corporate governance practices, including whether or not they have adopted a code of ethics for senior financial officers and whether the audit committee includes at least one “audit committee financial expert;” and (v) requires the SEC, based on certain enumerated factors, to regularly and systematically review corporate filings.

Deposit Insurance
The Bank’s deposits are insured under the FDIA up to the maximum applicable limits and are subject to deposit insurance assessments designed to tie what banks pay for deposit insurance to the risks they pose. Under the FDIC’s assessment system for determining payments to the DIF, large IDIs with more than $10 billion in assets are assessed under a complex “scorecard” methodology that seeks to capture both the probability that an individual large IDI will fail and the magnitude of the impact on the DIF if such a failure occurs. The assessment base of a large IDI is its total assets less tangible equity.
The Volcker Rule
The Dodd-Frank Act prohibits banks and their affiliates from engaging in proprietary trading and investing in and sponsoring hedge funds and private equity funds. The statutory provision is commonly called the “Volcker Rule.” The Volcker Rule does not significantly impact the operations of the Company and the Bank, as we do not have any significant engagement in the businesses prohibited by the Volcker Rule.
Interchange Fees
Under the Durbin AmendmentThe Company is subject to the Dodd-Frank Act, the Federal Reserve adopted rules establishinggoverning interchange fees, which establish standards for assessing whether the interchange fees that may be charged with respect to certain electronic debit transactions are “reasonable and proportional” to the costs incurred by issuers for processing such transactions.
Interchange fees, or “swipe” fees, are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. Under the finalapplicable rules, the maximum permissible interchange fee is equal to no more than 21 cents plus 5 basis points of the transaction value for many types of debit interchange transactions. The Federal Reserve also adopted a rule to allow a debit card issuer to recover one cent per transaction for fraud prevention purposes if the issuer complies with certain fraud-related requirements required by the Federal Reserve. The Federal Reserve also has rules governing routing and exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.
Incentive Compensation
The Dodd-Frank Act requires the federal bank regulators and the SEC to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities, including us and the Bank, having at least $1 billion in total assets that encourage inappropriate risks by providing an executive officer, employee, director or principal stockholder with excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. In addition, these regulators must establish regulations or guidelines requiring enhanced disclosure to regulators of incentive-based compensation arrangements.
In June 2010, the Federal Reserve and FDIC issued comprehensive final guidance on incentive compensation policies intended to ensure that the incentive compensation policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive risk-taking. The guidance, which covers all employees that have the ability to materially affect the risk profile of an organization, either individually or as part of a group, is based upon the key principles that a banking organization’s incentive compensation arrangements should (i) provide incentives that appropriately balance risk and financial results in a manner that does not encourage employees to expose their organizations to imprudent risk, (ii) be compatible with effective internal controls and risk management and (iii) be supported by strong corporate governance, including active and effective oversight by the organization’s board of directors.
During the second quarter of 2016, the U.S. financial regulators, including the Federal Reserve and the SEC, proposed revised rules on incentive-based payment arrangements at specified regulated entities having at least $1 billion in total assets, but these proposed rules have not been finalized.
The Federal Reserve will review, as part of the regular, risk-focused examination process, the incentive compensation arrangements of banking organizations, such as us, that are not “large, complex banking organizations.” These reviews will be tailored to each organization based on the scope and complexity of the organization’s activities and the prevalence of incentive compensation arrangements. The findings of the supervisory initiatives will be included in reports of examination. Deficiencies will be incorporated into the organization’s supervisory ratings, which can affect the organization’s ability to make acquisitions and take other actions. Enforcement actions may be taken against a banking organization if its incentive compensation arrangements or related risk management control or governance processes pose a risk to the organization’s safety and soundness and the organization is not taking prompt and effective measures to correct the deficiencies.

In October 2022, the SEC adopted a final rule directing national securities exchanges and associations, including Nasdaq, to require policies mandating the recovery or “clawback” of excess incentive-based compensation earned by a current or former executive officer during the three fiscal years preceding a required accounting restatement, including to correct an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The excess compensation would be based on the amount the executive officer would have received had the incentive-based compensation been determined using the restated financials. The final rule requires the exchanges to propose conforming listing standards by February 26, 2023 and requires the standards to become effective no later than November 28, 2023. Each listed issuer, which includes the Company as a listed issuer on Nasdaq, would then be required to adopt a clawback policy within 60 days after its exchange’s listing standard has become effective. The Company will work to implement these new requirements as the rule becomes effective.
Proposed Legislation
Proposed legislation relating to the banking industry is introduced in almost every legislative session. Certain of such legislation could dramatically affect the regulation of the banking industry. We cannot predict if any such legislation will be adopted or if it is adopted how it would affect the business of Columbia Bank or the Company. Recent history has demonstrated that new legislation or changes to existing laws or regulations usually results in a greater compliance burden and therefore generally increases the cost of doing business.
Effects of Government Monetary Policy
Our earnings and growth are affected not only by general economic conditions, but also by the fiscal and monetary policies of the federal government, particularly the Federal Reserve. The Federal Reserve implements national monetary policy for such purposes as curbing inflation and combating recession, but its open market operations in U.S. government securities, control of the discount rate applicable to borrowings from the Federal Reserve, and establishment of reserve requirements against certain deposits influence the growth of bank loans, investments and deposits and also affect interest rates charged on loans or paid on deposits. The nature and impact of future changes in monetary policies and their impact on us cannot be predicted with certainty.

ITEM 1A.RISK FACTORS

ITEM 1A.RISK FACTORS
The following is a discussion of what we currently believe are the most significant risks and uncertainties that may affect our business, financial condition and future results.
National and global economic and other conditions could adversely affectRisks Relating to our future results of operations or market price of our stock.
Our business is directly impacted by factors such as economic, political and market conditions, broad trends in industry and finance, changes in government monetary and fiscal policies and inflation, foreign policy, and financial market volatility, all of which are beyond our control. Global economies continue to face significant challenges to achieving normalized economic growth rates and there are continuing concerns related to the level of U.S. government debt and fiscal actions that may be taken to address that debt. There can be no assurance that economic conditions will continue to improve, and these conditions could worsen. Any renewed deterioration in the economies of the nation as a whole or in our markets would have an adverse effect, which could be material, on our business, financial condition, results of operations and prospects, and could also cause the market price of our stock to decline.
Economic conditions in the market areas we serve may adversely impact our earnings and could increase our credit risk associated with our loan portfolio, the value of our investment portfolio and the availability of deposits.
Substantially all of our loan and deposit customers are businesses and individuals in Washington, Oregon and Idaho, and soft economies in these market areas could have a material adverse effect on our business, financial condition, results of operations and prospects. A deterioration in the market areas we serve could result in the following consequences, any of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects:
loan delinquencies may increase;
problem assets and foreclosures may increase;
collateral for loans made may decline in value, in turn reducing customers’ borrowing power, reducing the value of assets and collateral associated with existing loans;
certain securities within our investment portfolio could become other-than-temporarily impaired, requiring a write-down through earnings to fair value, thereby reducing equity;
low cost or non-interest bearing deposits may decrease; and
demand for our loan and other products and services may decrease.
Concentrations within our loan portfolio could result in increased credit risk in a challenging economy.
While our loan portfolio is diversified across business sectors, it is concentrated in commercial real estate and commercial business loans. These types of loans generally are viewed as having more risk of default than residential real estate loans or certain other types of loans or investments. In fact, the FDIC has issued pronouncements alerting banks of its concern about heavy loan concentrations. Because our loan portfolio contains commercial real estate and commercial business loans with relatively large balances, the deterioration of one or a few of these loans may cause a significant increase in our nonperforming loans. An increase in nonperforming loans could result in a loss of earnings from these loans, an increase in the provision for loan losses, or an increase in loan charge-offs, any of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects.
A large percentage of our loan portfolio is secured by real estate, in particular commercial real estate. Deterioration in the real estate market or other segments of our loan portfolio would lead to additional losses.
At December 31, 2019, 60% of our total gross loans were secured by real estate. Any renewed downturn in the economies or real estate values in the markets we serve could have a material adverse effect on both borrowers’ ability to repay their loans and the value of the real property securing such loans. Our ability to recover on defaulted loans would then be diminished, and we would be more likely to suffer losses on defaulted loans, any or all of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects.

Operations
A failure in or breach of our operational or security systems, or those of our third party service providers, including as a result of cyber-attacks,cyberattacks, could disrupt our business, result in unintentional disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs and cause losses.
As a financial institution, our operations rely heavily on the secure processing, storage and transmission of confidential and other information on our computer systems and networks. Any failure, interruption or breach in security or operational integrity of these systems could result in failures or disruptions in our online banking system, customer relationship management, general ledger, deposit and loan servicing and other systems. The security and integrity of our systems could be threatened byare susceptible to a variety of interruptions or information security breaches, including those caused by computer hacking, cyber- attacks,cyberattacks, electronic fraudulent activity or attempted theft of financial assets. We mayare not be able to anticipate, detect, or implement effective preventative measures against all threats, particularly because the techniques used by cyber criminalscybercriminals change frequently, often are not recognized until launched and can be initiated from a variety of sources. We cannot assure you that we will be able to adequately address all such failures, interruptions or security breaches that may have a material adverse impact on our business, financial condition, results of operations and prospects. While we have certain protective policies and procedures in place, the nature and sophistication of the threats continue to evolve. We may be required to expend significant additional resources in the future to modify and enhance our protective measures.
Due to the complexity and interconnectedness of information technology systems, the process of enhancing our systems can itself create a risk of systems disruptions and security issues. Additionally, we face the risk of operational disruption, failure, termination or capacity constraints of any of the third parties that facilitate our business activities, including exchanges, clearing agents, clearing houses or other financial intermediaries. Such parties can also be the source of an attack on, or breach of, our operational systems. Any failures,Failures, interruptions or security breaches in our information systems could damage our reputation, result in a loss of customer business, result in a violation of privacy or other laws, or expose us to civil litigation, regulatory fines or losses not covered by insurance, all of which could have a material adverse impact on our business, financial condition, results of operations and prospects. Further, as an investigation into a cyberattack is inherently unpredictable, it may take a significant amount of time for us to fully uncover the scope of and damage related to a cyberattack and develop an effective mitigation plan. During such time, damage related to a cyberattack may continue and communications to the public, customers, regulators, and other stakeholders may not be timely or accurate. Potential new regulations may require us to publicly disclose information about a cyberattack before the incident has been resolved or fully investigated.
The confidential information of our customers (including user names and passwords) can also be jeopardized from the compromise of customers’ personal electronic devices or as a result of a data security breach at an unrelated company. Losses due to unauthorized account activity could harm our reputation and may have a material adverse effect on our business, financial condition, results of operations and prospects.
Acquisitions and the integration of acquired businesses subject us to various risks and may not result in all of the benefits anticipated, future acquisitions may be dilutive to current shareholders and future acquisitions may be delayed, impeded or prohibited due to regulatory issues.
We have in the past sought, and expect in the future to continue to seek, to grow our business by acquiring other businesses. As of the date of this report, our proposed combination with Umpqua is pending consummation. Risks specifically associated with this pending merger can be found below under the heading “Risks Relating to our Pending Merger with Umpqua.” Our acquisitions, including our recently completed acquisition of Bank of Commerce, may not have the anticipated positive results, including results relating to: correctly assessing the asset quality of the assets being acquired; the total cost of integration including management attention and resources; the time required to complete the integration successfully; the amount of longer-term cost savings; being able to profitably deploy funds acquired in an acquisition; or the overall performance of the combined entity.
In addition, unexpected contingent liabilities can arise from the businesses we acquire. Integration of an acquired business can be complex and costly, sometimes including combining relevant accounting and data processing systems, financial reporting and management and internal controls, as well as managing relevant relationships with employees, clients, suppliers and other business partners. Integration efforts could divert management attention and resources, which could adversely affect these systems, processes or controls and our operations or results.
17

Acquisitions may also result in business disruptions that cause us to lose customers or cause customers to remove their accounts from us and move their business to competing financial institutions. It is possible that the integration process related to acquisitions could result in the disruption of our ongoing businesses or inconsistencies in standards, controls, procedures and policies that could adversely affect our ability to maintain relationships with clients, customers, depositors and employees. The loss of key employees in connection with an acquisition could adversely affect our ability to successfully conduct our business.
We may engage in additional future acquisitions involving the issuance of additional common stock and/or cash. Any such acquisitions and related issuances of stock may have a dilutive effect on EPS, book value per share or the percentage ownership of current shareholders. The use of cash as consideration in any such acquisitions could impact our capital position and may require us to raise additional capital.
Furthermore, notwithstanding our prior acquisitions, we cannot provide any assurance as to the extent to which we can continue to grow through acquisitions as this will depend on the availability of prospective target opportunities at valuations we find attractive and other factors. Among other things, acquisitions by financial institutions are subject to approval by a variety of federal and state regulatory agencies. Regulatory approvals could be delayed, impeded, restrictively conditioned or denied due to existing or new regulatory issues we have, or may have, with regulatory agencies. In addition, the Northwest is experiencing intensified consolidation in the banking industry, and we face significant competition from numerous other financial services institutions for attractive acquisition candidates, and many of these competitors have greater financial resources than we do.
Our business, financial condition, liquidity and results of operations have been, and may in the future be, adversely affected by the COVID-19 pandemic.
The COVID-19 pandemic has created economic and financial disruptions that have adversely affected, and may in the future adversely affect, our business, financial condition, liquidity and results of operations. The extent to which the COVID-19 pandemic will negatively affect our business, financial condition, liquidity and results of operations will depend on future developments, including the emergence of new variants of COVID-19 and the widespread availability, use and effectiveness of vaccines over the long term and against new variants, which are highly uncertain and cannot be predicted.
While financial markets rebounded from the significant declines that occurred earlier in the pandemic and global economic conditions showed signs of improvement during the second half of 2020 and in 2021, many of the circumstances that arose or became more pronounced after the onset of the COVID-19 pandemic persisted through the beginning of 2022, including (i) muted levels of business activity across many sectors of the economy, weakened consumer confidence and disruptions to the global supply chain; (ii) elevated levels of market volatility; (iii) the federal funds rate and yields on U.S. Treasury securities near zero; (iv) the exacerbation of recent inflationary trends; (v) heightened credit risk with regard to industries that have been most severely impacted by the pandemic; and (vi) higher cybersecurity, information security and operational risks as a result of work-from-home arrangements. Depending on the duration and severity of the COVID-19 pandemic going forward, as well as the effects of the pandemic on consumer and corporate confidence, the conditions noted above could continue for an extended period and other adverse developments may occur or reoccur.
Governmental authorities worldwide have taken increased measures to stabilize the markets and support economic growth. The continued success of these measures is unknown and they may not be sufficient to address future market dislocations or avert severe and prolonged reductions in economic activity, and certain authorities have indicated an intention, or are under pressure to, wind down certain of these measures to counter inflationary trends. We also face an increased risk of client disputes, litigation and governmental and regulatory scrutiny as a result of the effects of the COVID-19 pandemic on economic and market conditions.
The length of the pandemic and the efficacy of the extraordinary measures that have been put in place to address it are unknown. For example, the Omicron variant of COVID-19 has led to a spike in COVID-19 cases across the United States, has led to travel and other disruptions, and certain governmental authorities and other third parties have re-imposed restrictions in order to respond to the rise in cases attributable to the Omicron variant of COVID-19. The U.S. economy, as well as most other major economies, may continue to experience a recession, and we anticipate our businesses would be materially and adversely affected by a prolonged recession in the U.S. and other major markets. Further, the COVID-19 pandemic may also have the effect of heightening many of the other risks described in this “Risk Factors” section or in the “Risk Factors” section of any subsequent Quarterly Report we file on Form 10-Q.

Risks Relating to our Pending Merger with Umpqua
Failure to complete the proposed merger with Umpqua could negatively impact Columbia.
If the merger with Umpqua is not completed for any reason there may be various adverse consequences and Columbia may experience negative reactions from the financial markets and from its customers and employees. For example, Columbia’s business may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, the benefits from which may not be realized. Additionally, if the merger agreement is terminated, the market price of Columbia’s common stock could decline to the extent that current market prices reflect a market assumption that the merger will be beneficial and will be completed. Columbia also could be subject to litigation related to any failure to complete the merger or to proceedings commenced against Columbia to perform its obligations under the merger agreement. If the merger agreement is terminated under certain circumstances, Columbia may be required to pay a termination fee of $145 million to Umpqua.
Combining Columbia and Umpqua may be more difficult, costly or time-consuming than expected, and Columbia may fail to realize the anticipated benefits of the merger.
The success of the merger will depend, in part, on the ability to realize the anticipated cost savings from combining the businesses of Columbia and Umpqua. To realize the anticipated benefits and cost savings from the merger, Columbia and Umpqua must successfully integrate and combine their businesses in a manner that permits those cost savings to be realized without adversely affecting current revenues and future growth. If Columbia and Umpqua are not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings of the merger could be less than anticipated, and integration may result in additional and unforeseen expenses.
An inability to realize the full extent of the anticipated benefits of the merger and the other transactions contemplated by the merger agreement, as well as any delays encountered in the integration process, could have an adverse effect upon the revenues, levels of expenses and operating results of the combined company following the completion of the merger, which may adversely affect the value of the common stock of the combined company following the completion of the merger.
Columbia and Umpqua have operated and, until the completion of the merger, must continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the companies’ ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the merger. Integration efforts between the companies may also divert management attention and resources. These integration matters could have an adverse effect on Columbia during this transition period and for an undetermined period after completion of the merger on the combined company.
Furthermore, the board of directors and executive leadership of the combined company will consist of former directors and executive officers from each of Columbia and Umpqua. Combining the boards of directors and management teams of each company into a single board and a single management team could require the reconciliation of differing priorities and philosophies.
The combined company may be unable to retain Columbia and/or Umpqua personnel successfully after the merger is completed.
The success of the merger will depend in part on the combined company’s ability to retain the talent and dedication of key employees currently employed by Columbia and Umpqua. It is possible that these employees may decide not to remain with Columbia or Umpqua, as applicable, while the merger is pending or with the combined company after the merger is consummated. If Columbia and Umpqua are unable to retain key employees, including management, who are critical to the successful integration and future operations of the companies, Columbia and Umpqua could face disruptions in their operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment costs. In addition, following the merger, if key employees terminate their employment, the combined company’s business activities may be adversely affected, and management’s attention may be diverted from successfully hiring suitable replacements, all of which may cause the combined company’s business to suffer. Columbia and Umpqua also may not be able to locate or retain suitable replacements for any key employees who leave either company.
19

Columbia will be subject to business uncertainties and contractual restrictions while the merger with Umpqua is pending.
Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Columbia. These uncertainties may impair Columbia’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with Columbia to seek to change existing business relationships with Columbia. In addition, subject to certain exceptions, Columbia has agreed to operate its business in the ordinary course in all material respects and to refrain from taking certain actions that may adversely affect its ability to consummate the transactions contemplated by the merger agreement on a timely basis without the consent of Umpqua. These restrictions may prevent Columbia from pursuing attractive business opportunities that may arise prior to the completion of the merger.
Columbia has incurred and is expected to incur substantial costs related to the merger and integration.
Columbia has incurred and expects to incur a number of non-recurring costs associated with the merger. These costs include legal, financial advisory, accounting, consulting and other advisory fees, retention, severance and employee benefit-related costs, public company filing fees and other regulatory fees, financial printing and other printing costs, closing, integration and other related costs. Some of these costs are payable by Columbia regardless of whether or not the merger is completed.
The merger agreement between the Company and Umpqua may be terminated in accordance with its terms and the merger may not be completed.
The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include, among other things: (i) approval by each of the Columbia shareholders and the Umpqua shareholders of certain matters relating to the merger at each company’s respective special meeting (which approvals were obtained on January 26, 2022); (ii) the receipt of required regulatory approvals, including the approval of the FRB and the FDIC (which approvals were obtained on October 25, 2022 and January 5, 2023, respectively); and (iii) the absence of any order, injunction, decree or other legal restraint preventing the completion of the merger, the bank merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger, the bank merger or any of the other transactions contemplated by the merger agreement illegal. Each party’s obligation to complete the merger is also subject to certain additional customary conditions, including (a) subject to applicable materiality standards, the accuracy of the representations and warranties of the other party set forth in the merger agreement, (b) the performance in all material respects by the other party of its obligations under the merger agreement and (c) the receipt by each party of an opinion from its counsel to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986.
These conditions to the closing may not be fulfilled in a timely manner or at all, and, accordingly, the merger may not be completed. In addition, the parties can mutually decide to terminate the merger agreement at any time, before or after the requisite shareholder approvals, or Umpqua or Columbia may elect to terminate the merger agreement in certain other circumstances.
Our assumptions regarding the fair value of assets acquired could be inaccurate, which could materially and adversely affect our business, financial condition, results of operations, and future prospects.
Management makes various assumptions and judgments about the collectability of acquired loans, including the creditworthiness of borrowers and the value of the real estate and other assets serving as collateral for the repayment of secured loans. If our assumptions are incorrect, significant earnings volatility can occur and credit loss provisions may be needed to respond to different economic conditions or adverse developments in the acquired loan portfolio. Any increase in future loan losses could have a material adverse impact on our business, financial condition, results of operations and prospects.
If the goodwill we have recorded in connection with acquisitions becomes impaired, it could have a material adverse impact on our earnings and shareholders’ equity.
Accounting standards require that we account for acquisitions using the acquisition method of accounting. Under acquisition accounting, if the purchase price of an acquired company exceeds the fair value of its net assets, the excess is carried on the acquirer’s balance sheet as goodwill. In accordance with GAAP, our goodwill is evaluated for impairment on an annual basis or more frequently if events or circumstances indicate that a potential impairment exists. Such evaluation may be based on a variety of factors, including the quoted price of our common stock, market prices of common stock of other banking organizations, common stock trading multiples, DCF analysis and data from comparable acquisitions. Future evaluations of goodwill may result in impairment and ensuing write-downs, which could have a material adverse impact on our earnings and shareholders’ equity.
20

We may not be able to attract or retain key employees.
Our success depends in significant part on the skills of our management team and our ability to retain, recruit and motivate key officers and employees. We expect our future success to be driven in large part by the relationships maintained with our clients by our executives and other key employees. Leadership changes will occur from time to time, and we cannot predict whether significant resignations or other departures will occur or whether we will be able to recruit additional qualified personnel. Competition for senior executives and skilled personnel in the financial services and banking industry is intense, which means the cost of hiring, incentivizing and retaining skilled personnel may continue to increase. The increase in remote and hybrid work arrangements has also increased competition for skilled personnel, and our current or future approach to in-office or remote-work arrangements may not meet the needs or expectations of current or prospective employees or may not be perceived as favorable compared to arrangements offered by other companies, which could adversely affect our ability to attract and retain skilled and qualified personnel. We need to continue to attract and retain key personnel and to recruit qualified individuals to succeed existing key personnel to ensure the continued growth and successful operation of our business. The unexpected loss of any such employees, or the inability to recruit and retain qualified personnel in the future, could have a material adverse impact on our business, financial condition, results of operations and prospects. In addition, the scope and content of U.S. banking regulators' regulations and policies on incentive compensation, as well as changes to these regulations and policies, could adversely affect our ability to hire, retain and motivate our key employees.
Our ability to sustain or improve upon existing performance is dependent upon our ability to respond to technological change, and we may have fewer resources than some of our competitors to continue to invest in technological improvements.
The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. Many of our competitors have substantially greater resources to invest in technological improvements than we do. Our future success will depend, in part, upon our ability to address the needs of our clients by using technology to provide products and services that will satisfy client demands for convenience, as well as to create additional efficiencies in our operations. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. In addition, the implementation of technological changes and upgrades to maintain current systems and integrate new ones may also cause service interruptions, transaction processing errors and system conversion delays and may cause us to fail to comply with applicable laws. There can be no assurance that we will be able to successfully manage the risks associated with our increased dependency on technology.
Significant legal or regulatory actions could subject us to substantial uninsured liabilities and reputational harm and have a material adverse effect on our business and results of operations.
We are from time to time subject to claims and proceedings related to our operations. Claims and legal actions, including supervisory or enforcement actions by our regulators, or criminal proceedings by prosecutorial authorities, could involve large monetary claims, including civil money penalties or fines imposed by government authorities and significant defense costs. If the proposed merger with Umpqua is completed, the combined company will also be subject to the claims and proceedings related to Umpqua’s operations. To mitigate the cost of some of these claims, we maintain insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. However, our insurance coverage does not cover any civil money penalties or fines imposed by government authorities and may not cover all other claims that might be brought against us or continue to be available to us at a reasonable cost. As a result, we may be exposed to substantial uninsured liabilities, which could adversely affect our business, prospects, results of operations and financial condition. Substantial legal liability or significant regulatory action against us could cause significant reputational harm to us and/or could have a material adverse impact on our business, financial condition, results of operations and prospects. Because we primarily serve individuals and businesses located in the Northwest, any negative impact resulting from reputational harm, including any impact on our ability to attract and retain customers and employees, likely would be greater than if our business were more geographically diverse.
We are subject to a variety of operational risks, including reputational risk, legal and compliance risk, and the risk of fraud or theft by employees or outsiders, which may adversely affect our business and results of operations.
We are exposed to many types of operational risks, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, and unauthorized transactions by employees or operational errors, including clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems. These risks have increased in light of work-from-home arrangements implemented in response to the COVID-19 pandemic.
21

Our reputation and businesses may be adversely affected by negative publicity or information regarding our businesses and personnel, whether or not accurate or true, that may be posted on social media or other Internet forums or published by news organizations. The speed and pervasiveness with which information can be disseminated through these channels, in particular social media, may magnify risks relating to negative publicity.
If personal, non-public, confidential or proprietary information of customers in our possession were to be mishandled or misused, we could suffer significant regulatory consequences, reputational damage and financial loss. Such mishandling or misuse could include, for example, if such information were erroneously provided to parties who are not permitted to have the information, either by fault of our systems, employees, or counterparties, or where such information is intercepted or otherwise inappropriately taken by third parties.
Because the nature of the financial services business involves a high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. Our necessary dependence upon automated systems to record and process transactions and our large transaction volume may further increase the risk that technical flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect. We are also subject to disruptions of our operating systems arising from events that are wholly or partially beyond our control (for example, computer viruses or electrical or telecommunications outages, natural disasters, pandemics or other damage to property or physical assets) that can give rise to disruption of service to customers and to financial loss or liability. We are further exposed to the risk that our external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees as we are) and to the risk that our (or our vendors’) business continuity and data security systems prove to be inadequate. The occurrence of any of these risks could result in a diminished ability of us to operate our business (for example, by requiring us to expend significant resources to correct the defect), as well as potential liability to clients, reputational damage and regulatory intervention, each of which could have a material adverse impact on our business, financial condition, results of operations and prospects.
We face reputation and business risks due to our interactions with business partners, service providers and other third parties.
We rely on third parties to provide services to us and our clients or otherwise act as partners in our business activities in a variety of ways, including through the provision of key components of our business infrastructure. We expect these third parties to perform services for us, fulfill their obligations to us, accurately inform us of relevant information, and conduct their activities in a manner that reflects positively on our brand and business. Although we manage exposure to such third-party risk through a variety of means, including the performance of due diligence and ongoing monitoring of vendor performance, there can be no assurance these efforts will be effective. Any failure of our business partners, service providers or other third parties to meet their commitments to us or to perform in accordance with our expectations could result in operational disruptions, increased expenditures, regulatory actions in which we may be held responsible for the actions of third parties, damage to our reputation and the loss of clients, which in turn could harm our business and operations, strategic growth objectives and financial performance. Because of the COVID-19 pandemic, many of our counterparties and third-party service providers have been, and may further be, affected by the continuing shift to work-from-home or hybrid-work arrangements, market volatility and other factors that increase their risk of business disruption or that may otherwise affect their ability to perform under the terms of any agreements with us or provide essential services.
Our third-party partners may also rely on their own business partners and service providers in the ordinary course of their business. Although we seek to diversify our exposure to third-party partners in order to increase our resiliency, we are nevertheless exposed to the risk that a disruption or other information technology event at a common service provider to our vendors could impede their ability to provide products or services to us, which in turn could harm our business and operations, strategic growth objectives and financial performance.
Failure to maintain effective internal control over financial reporting or disclosure controls and procedures may adversely affect our business and results of operations.
Management regularly reviews and updates our internal control over financial reporting, disclosure controls and procedures, and corporate governance policies and procedures. We maintain controls and procedures to mitigate risks such as processing system failures or errors and customer or employee fraud, and we maintain insurance coverage for certain of these risks. Any system of controls and procedures, however well designed and operated, is based in part on certain assumptions and provides only reasonable, not absolute, assurances that the objectives of the system are met. Events could occur which are not prevented or detected by our internal controls, are not insured against, or are in excess of our insurance limits. Any failure or circumvention of our controls and procedures, or failure to comply with regulations related to controls and procedures, could have an adverse effect on our business, financial condition, results of operations and prospects.

Interest Rate and Credit Risks
Economic conditions in the market areas we serve may adversely impact our earnings and could increase our credit risk associated with our loan portfolio, the value of our investment portfolio and the availability of deposits.
Substantially all of our loan and deposit customers are businesses and individuals in Washington, Oregon, Idaho and California, and soft economies in these market areas could have a material adverse effect on our business, financial condition, results of operations and prospects. A deterioration in the market areas we serve could result in consequences, including the following, any of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects:
loan delinquencies may increase;
problem assets and foreclosures may increase;
collateral for loans made may decline in value, in turn reducing customers’ borrowing power, reducing the value of assets and collateral associated with existing loans;
certain securities within our investment portfolio could require an allowance for credit losses, requiring a write-down through earnings to fair value, thereby reducing equity;
low-cost or noninterest-bearing deposits may decrease; and
demand for our loan and other products and services may decrease.
Concentrations within our loan portfolio could result in increased credit risk in a challenging economy.
While our loan portfolio is diversified across business sectors, it is concentrated in commercial real estate and commercial business loans. These types of loans generally are viewed as having more risk of default than residential real estate loans or certain other types of loans or investments. In fact, the FDIC has issued pronouncements alerting banks of its concern about heavy loan concentrations. Commercial real estate valuations can be significantly affected over relatively short periods of time by changes in business climate, economic conditions, interest rates, and, in many cases, the results of operations of businesses and other occupants of the real property. Emerging and evolving factors such as the shift to work-from-home or hybrid-work arrangements, changing consumer preferences (including online shopping), COVID-19-related restrictions and resulting changes in occupancy rates as a result of these and other trends can also impact such valuations over relatively short periods. Because our loan portfolio contains commercial real estate and commercial business loans with relatively large balances, the deterioration of one or a few of these loans may cause a significant increase in our nonperforming loans. An increase in nonperforming loans could result in a loss of earnings from these loans, an increase in the provision for loan losses, or an increase in loan charge-offs, any of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects.
A large percentage of our loan portfolio is secured by real estate, in particular commercial real estate. Deterioration in the real estate market or other segments of our loan portfolio would lead to additional losses.
As of December 31, 2022, 64% of our total gross loans were secured by real estate. Any renewed downturn in the economies or real estate values in the markets we serve could have a material adverse effect on both borrowers’ ability to repay their loans and the value of the real property securing such loans. Our ability to recover on defaulted loans would then be diminished, and we would be more likely to suffer losses on defaulted loans, any or all of which would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects.
Our allowance may not be adequate to cover future loan losses, which could adversely affect earnings.
We maintain an allowance for credit losses (for periods prior to January 1, 2020, referred to as the allowance for loan and lease losses) in an amount that we believe is adequate to provide for losses inherent in our loan portfolio. While we strive to carefully monitor credit quality and to identify loans that may become nonperforming, at any time there are loans in the portfolio that could result in losses but that have not been identified as nonperforming or potential problem loans. We cannot be sure that we will be able to identify deteriorating loans before they become nonperforming assets or that we will be able to limit losses on those loans that have been identified. Additionally, the process for determining the allowance requires different, subjective and complex judgments about the future impact from current economic conditions that might impair the ability of borrowers to repay their loans. As a result, future significant increases to the allowance may be necessary. Future increases to the allowance may be required based on changes in the composition of the loans comprising the portfolio, deteriorating values in underlying collateral (most of which consists of real estate) and changes in the financial condition of borrowers, such as may result from changes in economic conditions, or as a result of actual future events differing from assumptions used by management in determining the allowance.

23

We have adopted ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) MeasurementTable of Credit Losses on Financial InstrumentsContents (“CECL”) effective January 1, 2020. This standard requires financial institutions to determine periodic estimates of lifetime expected credit losses on financial instruments and other commitments to extend credit. This standard changes the prior incurred loss model for recognizing credit losses, and adoption of the new standard requires us to increase our allowance, and may greatly increase the types of data we need to collect and review to determine the appropriate level of the allowance. 
Additionally, banking regulators, as an integral part of their supervisory function, periodically review our allowance. These regulatory agencies may require us to increase the allowance. Any increase in the allowance would have an adverse effect, which could be material, on our financial condition and results of operations.

Nonperforming assets take significant time to resolve and could adversely affect our results of operations and financial condition.
Our nonperforming assets adversely affect our net income in various ways. We do not record interest income on nonaccrual loans, thereby adversely affecting our income and increasingincome. Moreover, nonaccrual loans increase our loan administration costs. Assets acquired by foreclosure or similar proceedings are recorded at fair value less estimated costs to sell. The valuation of these foreclosed assets is periodically updated and resulting losses, if any, are charged to earnings in the period in which they are identified. An increase in the level of nonperforming assets also increases our risk profile and may impact the capital levels our regulators believe is appropriate in light of such risks. We utilize various techniques such as loan sales, workouts, and restructurings to manage our problem assets. Decreases in the value of these problem assets, the underlying collateral, or in the borrowers’ performance or financial condition would have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects. In addition, the resolution of nonperforming assets requires significant commitments of time from management and staff, which can be detrimental to performance of their other responsibilities. We may experience increases in nonperforming loans in the future.
AcquisitionsFluctuating interest rates could adversely affect our business.
Significant increases in market interest rates on loans, or the perception that an increase may occur, could adversely affect both our ability to originate new loans and the integration of acquired businesses subject usour ability to various risks and may notgrow. Conversely, decreases in interest rates could result in allan acceleration of loan prepayments. An increase in market interest rates could also adversely affect the benefits anticipated, future acquisitions may be dilutiveability of our floating-rate borrowers to current shareholdersmeet their higher payment obligations. If this occurred, it could cause an increase in nonperforming assets and future acquisitions may be delayed, impeded or prohibited due to regulatory issues.
We have in the past and expect in the future seek to grow our business by acquiring other businesses. Our acquisitions may not have the anticipated positive results, including results relating to: correctly assessing the asset quality of the assets being acquired; the total cost of integration including management attention and resources; the time required to complete the integration successfully; the amount of longer-term cost savings; being able to profitably deploy funds acquired in an acquisition; or the overall performance of the combined entity.
In addition, unexpected contingent liabilities can arise from the businesses we acquire. Integration of an acquired business can be complex and costly, sometimes including combining relevant accounting and data processing systems, financial reporting and management and internal controls, as well as managing relevant relationships with employees, clients, suppliers and other business partners. Integration efforts could divert management attention and resources,charge-offs, which could adversely affect these systems, processes or controlsour business.
Further, our profitability is dependent to a large extent upon net interest income, which is the difference (or “spread”) between the interest earned on loans, securities and our operations or results.
Acquisitions may also resultother interest-earning assets and the interest paid on deposits, borrowings, and other interest-bearing liabilities. Because of the differences in business disruptions that cause us to lose customers or cause customers to remove their accounts from usmaturities and move their business to competing financial institutions. It is possible that the integration process related to acquisitions could result in the disruptionrepricing characteristics of our ongoing businesses or inconsistenciesinterest-earning assets and interest-bearing liabilities, changes in standards, controls, proceduresinterest rates do not produce equivalent changes in interest income earned on interest-earning assets and policies thatinterest paid on interest-bearing liabilities. Accordingly, fluctuations in interest rates could adversely affect our abilityinterest rate spread, and, in turn, our profitability. The Federal Reserve raised benchmark interest rates throughout 2022 and may continue to maintain relationships with clients, customers, depositorsraise interest rates in response to economic conditions, particularly inflationary pressures.Increases in interest rates, to combat inflation or otherwise, may result in a change in the mix of noninterest and employees. The loss of key employees in connection with an acquisition could adversely affect our ability to successfully conduct our business.
We may engage in additional future acquisitions involving the issuance of additional common stock and/or cash. Any such acquisitionsinterest-bearing accounts, and related issuances of stock may have a dilutive effect on EPS, book value per shareotherwise have unpredictable effects.For example, increases in interest rates may result in increases in the number of delinquencies, bankruptcies or the percentage ownership of current shareholders. The use of cash as considerationdefaults by clients and more nonperforming assets and net charge-offs, decreases in any such acquisitions could impact our capital position and may require us to raise additional capital.
Furthermore, notwithstanding our recent acquisitions, we cannot provide any assurance asdeposit levels, decreases to the extentdemand for interest rate-based products and services, including loans, and changes to the level of off-balance sheet market-based investments preferred by our clients, each of which we canmay reduce our interest rate spread. Lower rates would continue to grow through acquisitions as this will depend on the availability of prospective target opportunities at valuations we find attractive and other factors. Among other things, acquisitions by financial institutions are subject to approval by a variety of federal and state regulatory agencies. Regulatory approvals could be delayed, impeded, restrictively conditioned or denied due to existing or new regulatory issues we have, or may have, with regulatory agencies. In addition, the Northwest is experiencing intensified consolidation and we face significant competition from numerous other financial services institutions for attractive acquisition candidates, and many of these competitors have greater financial resources than we do.
Our assumptions regarding the fair value of assets acquired could be inaccurate, which could materiallyconstrain our interest rate spread and adversely affect our business forecasts. We are unable to predict changes in interest rates, which are affected by factors beyond our control, including inflation, deflation, recession, unemployment, money supply and other changes in financial condition, resultsmarkets.
Interest rates on certain of operations, and future prospects.
Management makes various assumptions and judgments about the collectability of acquired loans, including the creditworthiness of borrowersour outstanding financial instruments are subject to change based on regulatory developments, which could adversely affect our revenue, expenses and the value of those financial instruments.
LIBOR and certain other “benchmarks” are the real estatesubject of recent national, international and other assets serving as collateralregulatory guidance and proposals for reform. These reforms may cause such benchmarks to perform differently than in the past or have other consequences which cannot be predicted. The United Kingdom’s Financial Conduct Authority and the benchmark administrator for the U.S. Dollar LIBOR have announced that the publication of the most commonly used U.S. Dollar LIBOR settings will cease to be provided or cease to be representative after June 30, 2023. In March 2022, the U.S. Dollar Adjustable Interest Rate (LIBOR) Act (the “LIBOR Act”) was enacted, providing a uniform approach for replacing LIBOR as a reference interest rate in new contracts as soon as practicable and in so-called “tough legacy” contracts. Tough legacy contracts are contracts that do not include effective fallback provisions, for example, because they have no provisions for a replacement benchmark. Under the LIBOR Act, references to the most common tenors of LIBOR in these contracts will be replaced automatically to reference a SOFR-based benchmark interest rate identified in Federal Reserve regulations. In December 2022, the Federal Reserve issued final regulations identifying benchmark replacements, based on SOFR, for various types of contracts subject to the LIBOR Act. We may be adversely impacted by the changes involving LIBOR and other benchmark rates as a result of our business activities and our underlying operations, and interest rates on our loans, deposits, derivatives and other financial instruments tied to LIBOR rates, as well as the revenue and expenses associated with those financial instruments, may be adversely affected.
24

There continues to be substantial uncertainty as to the ultimate effects of LIBOR transition, including with respect to the acceptance and use of SOFR or other alternative benchmark rates. The characteristics of these new rates are not identical to the benchmarks they seek to replace, will not produce the exact economic equivalent as those benchmarks, and may perform differently in a variety of market conditions compared to those benchmarks. For example, during the COVID-19 pandemic period, there has been more volatility in relation to SOFR as compared to LIBOR. The SOFR markets have not yet developed into robust markets, which may present continuing risks as the June 30, 2023 LIBOR cessation date approaches. At this time, it is not possible to predict whether these recommendations and proposals will be broadly accepted, whether they will continue to evolve, and what the effect of their implementation may be on the markets for floating-rate financial instruments.
Our business depends on our ability to successfully manage credit risk.
The operation of our business requires us to manage credit risk. As a lender, we are exposed to the risk that our borrowers will be unable to repay their loans according to their terms, and that the collateral securing repayment of secured loans. If our assumptionstheir loans, if any, may not be sufficient to ensure repayment. In addition, there are incorrect, significant earnings volatility can occur and credit loss provisionsrisks inherent in making any loan, including risks with respect to the period of time over which the loan may be neededrepaid, risks relating to respondproper loan underwriting, risks resulting from changes in economic and industry conditions and risks inherent in dealing with individual borrowers. In order to differentsuccessfully manage credit risk, we must, among other things, maintain disciplined and prudent underwriting standards and ensure that our bankers follow those standards. The weakening of these standards for any reason, such as an attempt to attract higher yielding loans, a lack of discipline or diligence by our employees in underwriting and monitoring loans, the inability of our employees to adequately adapt policies and procedures to changes in economic or any other conditions or adverse developmentsaffecting borrowers and the quality of our loan portfolio, may result in the acquired loan portfolio. Anydefaults, foreclosures and additional charge-offs and may necessitate that we increase in future loan lossesour ACL, each of which could adversely affect our net income. As a result, our inability to successfully manage credit risk could have a material adverse impacteffect on our business, financial condition, results of operations and prospects.

We may be required, in the future, to recognize a credit loss with respect to investment securities.
Our securities portfolio currently includes securities with unrecognized losses. As of December 31, 2022, gross unrealized losses in our securities portfolio were $694.3 million. We may continue to observe declines in the fair market value of these securities. Securities issued by certain states and municipalities may come under scrutiny due to concerns about credit quality. Although management believes the credit quality of the Company’s state and municipal securities portfolio to be good, there can be no assurance that the credit quality of these securities will not decline in the future. We evaluate the securities portfolio for any securities with an associated credit loss each reporting period, as required by GAAP in the United States. There can be no assurance, however, that future evaluations of the securities portfolio will not require us to recognize credit losses with respect to these and other holdings. For example, it is possible that government-sponsored programs to allow mortgages to be refinanced to lower rates could materially adversely impact the yield on our portfolio of mortgage-backed securities, since a significant portion of our investment portfolio is composed of such securities.
We are exposed to the risk of environmental liabilities in connection with real properties acquired.
During the ordinary course of business, we foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If previously unknown or undisclosed hazardous or toxic substances are discovered, we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses which may materially reduce the affected property’s value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement polices with respect to existing laws may increase our exposure to environmental liability. Although we have policies and procedures which require the performance of an environmental review at the time of underwriting a loan secured by real property, and also before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on our financial condition and results of operations.
Funding and Liquidity Risks
Our management of capital could adversely affect profitability measures and the market price of our common stock and could dilute the holders of our outstanding common stock.
Our capital ratios are significantly higher than regulatory minimums. We may lower our capital ratios through selective acquisitions that meet our disciplined criteria, share repurchase plans, organic loan growth, investment in securities, or a combination of all four. We continually evaluate opportunities to expand our business through strategic acquisitions. There can be no assurance that we will be able to negotiate future acquisitions on terms acceptable to us.
25

Conversely, there may be circumstances under which it would be prudent to consider alternatives for raising capital to take advantage of significant acquisition opportunities or in response to changing economic conditions. In addition, we may need to raise additional capital in the future to have sufficient capital resources and liquidity to meet our commitments and fund our business needs and future growth, particularly if the quality of our assets or earnings were to deteriorate significantly. We may not be able to raise additional capital when needed on terms acceptable to us or at all. Our ability to raise additional capital, if needed, will depend on, among other things, conditions in the capital markets at the time, which are outside our control, and our financial performance. Further, if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and would then have to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when needed could have a material adverse effect on our business, financial condition, results of operations and prospects. In addition, any capital raising alternatives could dilute the holders of our outstanding common stock and may adversely affect the market price of our common stock.
Conditions in the financial markets may limit access to additional funding to meet liquidity needs.
We may need or want to raise additional capital in the future to provide us with sufficient capital resources and liquidity to meet our commitments and business needs, particularly if our asset quality or earnings were to deteriorate significantly. Our ability to raise additional capital will depend on, among other things, conditions in the capital markets at that time, which are outside of our control, and our financial performance. Economic conditions and any loss of confidence in financial institutions generally may increase our cost of funding and limit access to certain customary sources of capital.
There can be no assurance that capital will be available on acceptable terms or at all. Any occurrence that may limit our access to the capital markets, such as a decline in the confidence of equity or debt purchasers, or counterparties participating in capital markets, may adversely affect our capital costs and our ability to raise capital and, potentially, our liquidity. Also, if we need to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise capital and would have to compete with those institutions for investors. An inability to raise additional capital on acceptable terms when needed could have a materially adverse effect on our business, financial condition and results of operations.
If the goodwill we have recorded in connection with acquisitions becomes impaired, it could have a material adverse impact on our earningsLegal, Accounting and shareholders’ equity.
Accounting standards require that we account for acquisitions using the acquisition method of accounting. Under acquisition accounting, if the purchase price of an acquired company exceeds the fair value of its net assets, the excess is carried on the acquirer’s balance sheet as goodwill. In accordance with GAAP, our goodwill is evaluated for impairment on an annual basis or more frequently if events or circumstances indicate that a potential impairment exists. Such evaluation may be based on a variety of factors, including the quoted price of our common stock, market prices of common stock of other banking organizations, common stock trading multiples, discounted cash flows, and data from comparable acquisitions. Future evaluations of goodwill may result in impairment and ensuing write-downs, which could have a material adverse impact on our earnings and shareholders’ equity.
Fluctuating interest rates could adversely affect our business.
Significant increases in market interest rates on loans, or the perception that an increase may occur, could adversely affect both our ability to originate new loans and our ability to grow. Conversely, decreases in interest rates could result in an acceleration of loan prepayments. An increase in market interest rates could also adversely affect the ability of our floating-rate borrowers to meet their higher payment obligations. If this occurred, it could cause an increase in nonperforming assets and charge offs, which could adversely affect our business.

Further, our profitability is dependent to a large extent upon net interest income, which is the difference (or “spread”) between the interest earned on loans, securities and other interest-earning assets and the interest paid on deposits, borrowings, and other interest-bearing liabilities. Because of the differences in maturities and repricing characteristics of our interest-earning assets and interest-bearing liabilities, changes in interest rates do not produce equivalent changes in interest income earned on interest-earning assets and interest paid on interest-bearing liabilities. Accordingly, fluctuations in interest rates could adversely affect our interest rate spread, and, in turn, our profitability.
Interest rates on our outstanding financial instruments might be subject to change based on regulatory developments, which could adversely affect our revenue, expenses, and the value of those financial instruments.
LIBOR and certain other “benchmarks” are the subject of recent national, international, and other regulatory guidance and proposals for reform. These reforms may cause such benchmarks to perform differently than in the past or have other consequences which cannot be predicted. On July 27, 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, publicly announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. It is unclear whether, at that time, LIBOR will continue to be viewed as an acceptable market benchmark, or what rate or rates may become acceptable alternatives to or replacements for LIBOR. If LIBOR ceases to be recognized as an acceptable benchmark or to exist or if an alternative rate or rates become accepted alternatives or replacements for LIBOR, interest rates on our loans, deposits, derivatives, and other financial instruments tied to LIBOR rates, as well as the revenue and expenses associated with those financial instruments, may be adversely affected. Further, any uncertainty regarding the continued use and reliability of LIBOR as a benchmark interest rate could adversely affect the value of our loans, deposits, derivatives, and other financial instruments tied to LIBOR rates.
Regulators, industry groups and certain committees (e.g., the Alternative Reference Rates Committee) have, among other things, published recommended fallback language for LIBOR-linked financial instruments, identified recommended alternatives for certain LIBOR rates (e.g., the Secured Overnight Financing Rate as the recommended alternative to U.S. Dollar LIBOR), and proposed implementations of the recommended alternatives in floating rate instruments. At this time, it is not possible to predict whether these recommendations and proposals will be broadly accepted, whether they will continue to evolve, and what the effect of their implementation may be on the markets for floating-rate financial instruments
Our business depends on our ability to successfully manage credit risk.
The operation of our business requires us to manage credit risk. As a lender, we are exposed to the risk that our borrowers will be unable to repay their loans according to their terms, and that the collateral securing repayment of their loans, if any, may not be sufficient to ensure repayment. In addition, there are risks inherent in making any loan, including risks with respect to the period of time over which the loan may be repaid, risks relating to proper loan underwriting, risks resulting from changes in economic and industry conditions and risks inherent in dealing with individual borrowers. In order to successfully manage credit risk, we must, among other things, maintain disciplined and prudent underwriting standards and ensure that our bankers follow those standards. The weakening of these standards for any reason, such as an attempt to attract higher yielding loans, a lack of discipline or diligence by our employees in underwriting and monitoring loans, the inability of our employees to adequately adapt policies and procedures to changes in economic or any other conditions affecting borrowers and the quality of our loan portfolio, may result in loan defaults, foreclosures and additional charge-offs and may necessitate that we increase our ALLL, each of which could adversely affect our net income. As a result, our inability to successfully manage credit risk could have a material adverse effect on our business, financial condition, results of operations and prospects.

Compliance Risks
We operate in a highly regulated environment and changes to or increases in, or supervisory enforcement of, banking or other laws and regulations or governmental fiscal or monetary policies could adversely affect us.
We are subject to extensive regulation, supervision and examination by federal and state banking authorities. In addition, as a publicly-traded company, we are subject to regulation by the SEC. Any change in applicable regulations or federal, state or local legislation or in policies or interpretations or regulatory approaches to compliance and enforcement, income tax laws andor accounting principles could have a substantial impact on us and our operations. Changes in laws and regulations may also increase our expenses by imposing additional fees or taxes or restrictions on our operations. Additional legislation and regulations that could significantly affect our powers, authority and operations may be enacted or adopted in the future, which could have a material adverse effect on our business, financial condition, results of operations and prospects. Failure to appropriately comply with any such laws, regulations or principles could result in sanctions by regulatory agencies or damage to our reputation, all of which could adversely affect our business, financial condition or results of operations. For example, the Dodd-Frank Act was enacted in July 2010. Among other provisions, the legislation (i) created the CFPB with broad powers to regulate consumer financial products such as credit cards and mortgages, (ii) resulted in new capital requirements from federal banking agencies, (iii) placed new limits on electronic debit card interchange fees and (iv) required the SEC and national stock exchanges to adopt significant new corporate governance and executive compensation reforms, some of which have yet to be promulgated. The Dodd-Frank Act and regulations that have been adopted thereunder have increased the overall costs of regulatory compliance, and further regulatory developments whether related to Dodd-Frank or otherwise may lead to additional costs. In addition, the CFPB has broad rulemaking authority and is the principal federal regulatory agency responsible for the supervision and enforcement of a wide range of consumer protection laws for banks with greater than $10 billion in assets.
If we fail to maintain appropriate levels of capital or liquidity, we could become subject to formal or informal enforcement actions that may impose restrictions on our business, including limiting our lending activities or our ability to expand, requiring us to raise additional capital (which may be dilutive to shareholders) or requiring regulatory approval to pay dividends or otherwise return capital to shareholders. We also face the risk of becoming subject to new or more stringent requirements in connection with the introduction of new regulations or modifications of existing regulations, which could require us to hold more capital or liquidity or have other adverse effects on our business or profitability.
26

Further, regulators have significant discretion and authority to prevent or remedy unsafe or unsound practices or violations of laws or regulations by financial institutions and holding companies in the performance of their supervisory and enforcement duties. The exercise of regulatory authority may have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects. Additionally, our business is affected significantly by the fiscal and monetary policies of the U.S. federal government and its agencies, including the Federal Reserve.
We cannot accurately predict the full effects of recent legislation or the various other governmental, regulatory, monetary and fiscal initiatives which have been and may be enacted on the financial markets, on the Company and on the Bank. The terms and costs of these activities, or any worsening of current financial market and economic conditions, could materially and adversely affect our business, financial condition and results of operations, as well as the trading price of our common stock.
WeChanges in accounting standards could materially impact our financial statements.
From time to time, the FASB and the SEC change the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can materially impact how we record and report our financial condition and results of operations.
Risks Relating to Markets and External Events
National and global economic and other conditions could adversely affect our future results of operations or market price of our stock.
Our business is directly impacted by factors such as economic, political and market conditions, broad trends in industry and finance, changes in government monetary and fiscal policies and inflation, foreign policy, and financial market volatility, all of which are beyond our control. Global economies continue to face significant challenges to achieving normalized economic growth rates. Any renewed deterioration in the economies of the nation as a whole or in our markets would have an adverse effect, which could be material, on our business, financial condition, results of operations and prospects, and could also cause the market price of our stock to decline. If recessionary economic conditions or an economic downturn develop, they would likely have a negative financial impact across the financial services industry, including on us. If these conditions are more severe, the extent of the negative impact on our business and financial performance can increase and be more severe, including the adverse effects listed above and discussed throughout this “Risk Factors” section.
Supply chain constraints, robust demand and labor shortages have led to persistent inflationary pressures throughout the economy. Volatility and uncertainty related to inflation and the effects of inflation, which may lead to increased costs for businesses and consumers and potentially contribute to poor business and economic conditions generally, may also enhance or contribute to some of the risks discussed herein. For example, higher inflation, or volatility and uncertainty related to inflation, could reduce demand for our products, adversely affect the creditworthiness of our borrowers or, result in lower values for our investment securities and other interest-earning assets, and increase expense related to talent acquisition and retention.
Additionally, economic conditions, financial markets and inflationary pressures may be required, inadversely affected by the future, to recognize impairment with respect to investment securities.
Our securities portfolio currently includes securities with unrecognized losses. At December 31, 2019, gross unrealized losses in our securities portfolio were $20.4 million. We may continue to observe declines inimpact of current or anticipated geopolitical uncertainties, military conflicts, including Russia’s invasion of Ukraine, pandemics, including the fair market value of these securities. Securities issuedCOVID-19 pandemic, and global, national and local responses thereto by certain states and municipalities have recently come under scrutiny due to concerns about credit quality. Although management believes the credit quality of the Company’s state and municipal securities portfolio to be good, there can be no assurance that the credit quality of these securities will not decline in the future. We evaluate the securities portfolio for any other-than-temporary impairment each reporting period, as required by GAAP in the United States. There can be no assurance, however, that future evaluations of the securities portfolio will not require us to recognize impairment charges with respect to thesegovernmental authorities and other holdings. For example, it is possiblethird parties. These unpredictable events could create, increase or prolong economic and financial disruptions and volatility that government-sponsored programs to allow mortgages to be refinanced to lower rates could materially adversely impact the yield onaffects our portfoliobusiness, financial condition, capital and results of mortgage-backed securities, since a significant portion of our investment portfolio is composed of such securities.operations.
Substantial competition in our market areas could adversely affect us.
Commercial banking is a highly competitive business. We compete with other commercial banks, savings and loan associations, credit unions and finance, insurance and other non-depository companies operating in our market areas. We also experience competition, especially for deposits, from Internet-based banking institutions, which have grown rapidly in recent years. We are subject to substantial competition for loans and deposits from other financial institutions. Some of our competitors are not subject to the same degree of regulation and restriction as we are and/or have greater financial resources than we do. Some of our competitors may have liquidity issues, which could impact the pricing of deposits, loans and other financial products in our markets. Our inability to effectively compete in our market areas could have a material adverse impact on our business, financial condition, results of operations and prospects.

Climate change concerns could adversely affect our business, affect client activity levels and damage our reputation.
WeConcerns over the long-term impacts of climate change have led and will continue to lead to governmental efforts around the world to mitigate those impacts. Consumers and businesses are also changing their behavior and business preferences as a result of these concerns. New governmental regulations or guidance relating to climate change, as well as changes in consumers’ and businesses’ behaviors and business preferences, may not be ableaffect whether and on what terms and conditions we will
27

engage in certain activities or offer certain products or services. The governmental and supervisory focus on climate change could also result in our becoming subject to attractnew or retain key employees.
Our success dependsheightened regulatory requirements relating to climate change, such as requirements relating to operational resiliency or stress testing for various climate stress scenarios. Any such new or heightened requirements could result in significant part onincreased regulatory, compliance or other costs or higher capital requirements. In connection with the skillstransition to a low carbon economy, legislative or public policy changes and changes in consumer sentiment could negatively impact the businesses and financial condition of our management teamclients, which may decrease revenues from those clients and our ability to retain, recruit and motivate key officers and employees. We expect our future success to be driven in large part byincrease the relationships maintainedcredit risk associated with our clients by our executivesloans and other key employees. Leadership changes will occur from timecredit exposures to time,those clients. Our business, reputation and we cannot predict whether significant resignations or other departures will occur or whether we will be able to recruit additional qualified personnel. Competition for senior executives and skilled personnel in the financial services and banking industry is intense, which means the cost of hiring, incentivizing and retaining skilled personnel may continue to increase. We need to continueability to attract and retain key personnelemployees may also be harmed if our response to climate change is perceived to be ineffective or insufficient.
Our business is subject to the risks of earthquakes, tsunamis, floods, fires and to recruit qualified individuals to succeed existing key personnel to ensureother natural catastrophic events and other events beyond our control.
A major catastrophe, such as an earthquake, tsunami, flood, fire or other natural disaster, including those caused or exacerbated by climate change, public health issues such as the continued growth and successful operationCOVID-19 or other pandemics, or other events beyond our control, could result in a prolonged interruption of our business. For example, our headquarters are located in Tacoma, Washington and we have operations throughout the Northwest, a geographical region that has been or may be affected by earthquakes, wildfires, tsunamis and flooding activity, and in Northern California, a geographical region that has been and continues to be affected by earthquakes and wildfires. Because we primarily serve individuals and businesses in the Northwest and Northern California, a natural disaster likely would have a greater impact on our business, operations and financial condition than if our business were more geographically diverse. The unexpected lossoccurrence of any such employees,of these natural disasters could negatively impact our performance by disrupting our operations or the inability to recruit and retain qualified personnel in the future,operations of our customers, which could have a material adverse impacteffect on our business, financial condition, results of operations and prospects. In addition, the scope and content of U.S. banking regulators' regulations and policies on incentive compensation, as well as changescash flows.
Risks Relating to these regulations and policies, could adversely affectInvestment in our ability to hire, retain and motivate our key employees.
Changes in accounting standards could materially impact our financial statements.
From time to time, the FASB and the SEC change the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can materially impact how we record and report our financial condition and results of operations.
FASB’s ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments, became effective on January 1, 2020. The amendments in this ASU introduce a new impairment model based on CECL rather than incurred losses. The CECL model applies to most debt instruments, including loan receivables and loan commitments.
Unlike the incurred loss models, the CECL model does not specify a threshold for the recognition of an impairment allowance. Rather, the Company must recognize an impairment allowance equal to its current estimate of expected credit losses for financial instruments as of the end of the reporting period. Measuring expected credit losses will most likely be a significant challenge for all entities, including the Company.
Further, the impairment allowance measured under the CECL model will differ from the impairment allowance measured under the Company’s prior incurred loss model. To initially apply the amendments, the Company has recorded a cumulative-effect adjustment to its Consolidated Balance Sheets as of January 1, 2020 (a modified retrospective approach). The adoption of the standard has resulted in an overall increase in the allowance for credit losses. It is also possible that the Company’s ongoing reported earnings and lending activity will be negatively impacted in periods following adoption.Stock
There can be no assurance as to the level of dividends we may pay on our common stock.
Holders of our common stock are only entitled to receive such dividends as our board of directors declares out of funds legally available for such payments. Although we have historically declared cash dividends on our common stock, we are not required to do so and there may be circumstances under which we would eliminate our common stock dividend in the future. This could adversely affect the market price of our common stock.
We rely on dividends and other payments from our bank for substantially all of our revenue.
We are a separate and distinct legal entity from the Bank, and we receive substantially all of our operating cash flows from dividends and other payments from the Bank. These dividends and payments are the principal source of funds to pay dividends on our capital stock and interest and principal on any debt we may have. Various federal and state laws and regulations limit the amount of dividends that the Bank may pay to us. Also, our right to participate in a distribution of assets upon a subsidiary’s liquidation or reorganization is subject to the prior claims of the subsidiary’s creditors. In the event the Bank is unable to pay dividends to us, we may not be able to service debt, pay obligations or pay dividends on our common stock. The inability to receive dividends from the Bank could have a material adverse impact on our business, financial condition, results of operations and prospects.

Our ability to sustain or improve upon existing performance is dependent upon our ability to respond to technological change, and we may have fewer resources than some of our competitors to continue to invest in technological improvements.
The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. Many of our competitors have substantially greater resources to invest in technological improvements than we do. Our future success will depend, in part, upon our ability to address the needs of our clients by using technology to provide products and services that will satisfy client demands for convenience, as well as to create additional efficiencies in our operations. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. In addition, the implementation of technological changes and upgrades to maintain current systems and integrate new ones may also cause service interruptions, transaction processing errors and system conversion delays and may cause us to fail to comply with applicable laws. There can be no assurance that we will be able to successfully manage the risks associated with our increased dependency on technology.
We are exposed to the risk of environmental liabilities in connection with real properties acquired.
During the ordinary course of business, we foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If previously unknown or undisclosed hazardous or toxic substances are discovered, we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses which may materially reduce the affected property’s value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement polices with respect to existing laws may increase our exposure to environmental liability. Although we have policies and procedures to perform an environmental review at the time of underwriting a loan secured by real property, and also before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on our financial condition and results of operations.
Significant legal or regulatory actions could subject us to substantial uninsured liabilities and reputational harm and have a material adverse effect on our business and results of operations.
We are from time to time subject to claims and proceedings related to our operations. Claims and legal actions, including supervisory or enforcement actions by our regulators, or criminal proceedings by prosecutorial authorities, could involve large monetary claims, including civil money penalties or fines imposed by government authorities and significant defense costs. To mitigate the cost of some of these claims, we maintain insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. However, our insurance coverage does not cover any civil money penalties or fines imposed by government authorities and may not cover all other claims that might be brought against us or continue to be available to us at a reasonable cost. As a result, we may be exposed to substantial uninsured liabilities, which could adversely affect our business, prospects, results of operations and financial condition. Substantial legal liability or significant regulatory action against us could cause significant reputational harm to us and/or could have a material adverse impact on our business, financial condition, results of operations and prospects. Because we primarily serve individuals and businesses located in the Northwest, any negative impact resulting from reputational harm, including any impact on our ability to attract and retain customers and employees, likely would be greater than if our business were more geographically diverse.
We are subject to a variety of operational risks, including reputational risk, legal risk and compliance risk, and the risk of fraud or theft by employees or outsiders, which may adversely affect our business and results of operations.
We are exposed to many types of operational risks, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, and unauthorized transactions by employees or operational errors, including clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems.
The public perception of financial institutions remains negative. Our reputation and businesses may be adversely affected by negative publicity or information regarding our businesses and personnel, whether or not accurate or true, that may be posted on social media or other Internet forums or published by news organizations. The speed and pervasiveness with which information can be disseminated through these channels, in particular social media, may magnify risks relating to negative publicity.

If personal, non-public, confidential or proprietary information of customers in our possession were to be mishandled or misused, we could suffer significant regulatory consequences, reputational damage and financial loss. Such mishandling or misuse could include, for example, if such information were erroneously provided to parties who are not permitted to have the information, either by fault of our systems, employees, or counterparties, or where such information is intercepted or otherwise inappropriately taken by third parties.
Because the nature of the financial services business involves a high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. Our necessary dependence upon automated systems to record and process transactions and our large transaction volume may further increase the risk that technical flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect. We are also subject to disruptions of our operating systems arising from events that are wholly or partially beyond our control (for example, computer viruses or electrical or telecommunications outages, natural disasters, disease pandemics or other damage to property or physical assets) that can give rise to disruption of service to customers and to financial loss or liability. We are further exposed to the risk that our external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees as we are) and to the risk that we (or our vendors’) business continuity and data security systems prove to be inadequate. The occurrence of any of these risks could result in a diminished ability of us to operate our business (for example, by requiring us to expend significant resources to correct the defect), as well as potential liability to clients, reputational damage and regulatory intervention, which could have a material adverse impact on our business, financial condition, results of operations and prospects.
Failure to maintain effective internal control over financial reporting or disclosure controls and procedures may adversely affect our business and results of operations.
Management regularly reviews and updates our internal control over financial reporting, disclosure controls and procedures, and corporate governance policies and procedures. We maintain controls and procedures to mitigate risks such as processing system failures or errors and customer or employee fraud, and we maintain insurance coverage for certain of these risks. Any system of controls and procedures, however well designed and operated, is based in part on certain assumptions and provides only reasonable, not absolute, assurances that the objectives of the system are met. Events could occur which are not prevented or detected by our internal controls, are not insured against, or are in excess of our insurance limits. Any failure or circumvention of our controls and procedures, or failure to comply with regulations related to controls and procedures, could have an adverse effect on our business, financial condition, results of operations and prospects.
Our business is subject to the risks of earthquakes, tsunamis, floods, fires and other natural catastrophic events.
A major catastrophe, such as an earthquake, tsunami, flood, fire or other natural disaster, could result in a prolonged interruption of our business. For example, our headquarters are located in Tacoma, Washington and we have operations throughout the Northwest, a geographical region that has been or may be affected by earthquake, tsunami and flooding activity. Because we primarily serve individuals and businesses in the Northwest, a natural disaster likely would have a greater impact on our business, operations and financial condition than if our business were more geographically diverse. The occurrence of any of these natural disasters could negatively impact our performance by disrupting our operations or the operations of our customers, which could have a material adverse effect on our financial condition, results of operations and cash flows.
We have various anti-takeover measures that could impede a takeover.
Our articles of incorporation include certain provisions that could make it more difficult to acquire us by means of a tender offer, a proxy contest, merger or otherwise. These provisions include certain non-monetary factors that our board of directors may consider when evaluating a takeover offer, and a requirement that any “Business Combination” be approved by the affirmative vote of no less than 66 2/3% of the total shares attributable to persons other than a “Control Person.” These provisions may have the effect of lengthening the time required for a person to acquire control of us through a tender offer, proxy contest or otherwise, and may deter any potentially hostile offers or other efforts to obtain control of us. This could deprive our shareholders of opportunities to realize a premium for their Columbia common stock, even in circumstances where such action is favored by a majority of our shareholders.

ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This discussion should be read in conjunction with our Consolidated Financial Statements and related notes in “Item 8. Financial Statements and Supplementary Data” of this report. In the following discussion, unless otherwise noted, references to increases or decreases in average balances in items of income and expense for a particular period and balances at a particular date refer to the comparison with corresponding amounts for the period or date for the previous year. For comparison of 2021 to 2020 results and other 2020 information not included herein, refer to “Management Discussion and Analysis of Financial Condition and Results of Operations” under Part II, Item 7 of our 2021 Form 10-K filed with the SEC on February 25, 2022.
Critical Accounting Policies and Estimates
We have established certain accounting policies in preparing our Consolidated Financial Statements that are in accordance with accounting principles generally accepted in the United States. Our significant accounting policies are presented in Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report. Certain of these policies require the use of judgments, estimates and economic assumptions which may prove inaccurate or are subject to variation that may significantly affect our reported results of operations and financial position for the periods presented or in future periods. Management believes that the judgments, estimates and economic assumptions used in the preparation of the Consolidated Financial Statements are appropriate given the factual circumstances at the time. We consider the following policies to be most critical in understanding the judgments that are involved in preparing our Consolidated Financial Statements.
Allowance for Loan and LeaseCredit Losses
The ALLLCompany’s determination of its ACL is ana critical accounting estimate of incurred credit losses in our loan portfolio at the balance sheet date. The primary components of the allowance are 1) loans collectively evaluated for impairment in accordance with the FASB ASC Topic 450, Contingencies (“ASC 450”), 2) loans individually determined to be impaired in accordance with the FASB ASC Subtopic 310-10, Receivables: Overall (“ASC 310-10”) and 3) loans acquired with deteriorated credit quality in accordance with FASB ASC Subtopic 310-30, Receivables: Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”).
The measure of estimated credit losses for the ASC 450 component is based upon the loss experience over a historical base period adjusted for a loss emergence period. The loss emergence period is an estimate of the period that it takes, on average, for us to identify the amount of loss incurred for a loan that has suffered a loss-causing event. Management then considers the effects of the following qualitative factors to ensure our allowance reflects the inherent losses in the loan portfolio:
Economic and business conditions;
Concentration of credit;
Lending management and staff;
Lending policies and procedures;
Loss and recovery trends;
Nature and volume of the portfolio;
Trends in problem loans, loan delinquencies and nonaccrual loans;
Quality of internal loan review; and
External factors.
These qualitative factors have a high degree of subjectivity and changes in any of the factors could have a significant impact on our calculation of the allowance. The qualitative adjustment by loan segment is based upon management's assessment of inherent losses within a range between the weighted historical loss factor by segment and the maximum consecutive quarterly losses in the relevant loss emergence period by segment over the historical base period.
The measure of estimated credit losses for the ASC 310-10 component begins if, based upon current information and events, we believe it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a TDR. When a loan has been identified as impaired, the amount of impairment will be measured using discounted cash flows, except when it is determined that the remaining source of repayment for the loan is the operation or liquidation of the underlying collateral. In these cases, the current fair value of the collateral, reduced by costs to sell, will be used in place of discounted cash flows. As a final alternative, the observable market price of the debt may be used to assess impairment. The Company predominantly uses the fair value of collateral approach based upon a reliable valuation.
Our allowance policy and the judgments, estimates and economic assumptions involved are described in greater detail in the “Allowance for Loan and Lease Losses and Unfunded Commitments and Letters of Credit” section of this discussion and in Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.

Adoption of Allowance for Credit Losses - ASC 326
In accordance with ASU 2016-13, the Company was required to adopt ASC 326 as of January 1, 2020.estimate. The allowance for credit losses under ASC 326 is an accounting estimate of expected losses over the contractual life of assets carried at amortized cost within the Company’s loan portfolio at the balance sheet date. The ASU requires a financial asset (or group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset.
The quantitative allowance is calculated using a discounted cash flowDCF approach with a probability of default methodology. The probability of default is an assumption derived from regression models which determine the relationship between historical defaults and certain economic variables. The Company determines a reasonable and supportable forecast and applies that forecast to the model to determine defaults over the forecast period. The forecast includes estimates for key economic variables. While there are several economic variables included, the ones most predominantly used in our models are unemployment rate, consumer price index, real gross domestic product and disposable personal income. Following the forecast period, the economic variables used to calculate the probability of default revert to a historical average. Other assumptions relevant to the discounted cash flow model to derive the quantitative allowance include the loss given default, which is the estimate of loss for a defaulted loan, and the discount rate applied to future cash flows. The model calculates the net present value of each loan using both the contractual and expected cash flows, respectively. The ACL is determined at the end of each quarter and is based on all relevant information and expectations at that time in accordance with GAAP and the ACL guidance. Future changes to the estimate are likely as new information becomes available regarding economic conditions, loan composition and identifiable risk factors. While quantifiable estimates are generated, management judgements regarding credit risks and the inherent imprecision with the models utilized support the overall ACL.
In addition to the quantitative portion of the allowance for credit losses, the Company also considers the effects of the following qualitative factors in its calculation of expected losses in the loan portfolio:
Economic and business conditions;
Concentration of credit;
Lending management and staff;
Lending policies and procedures;
Loss and recovery trends;
Nature and volume of the portfolio;
Trends in problem loans, loan delinquencies and nonaccrual loans;
Quality of internal loan review; and
External factors.Other external factors such as the effect of economic stimulus and loan modification programs.

These qualitative factors are based in quantitative factors but also include a high degree of subjectivity and changes in any of the factors could have a significant impact on our calculation of the allowance.
Loans for which repayment is expected to be provided substantially through the operation or sale of collateral are considered collateral-dependent. The allowance for credit losses for collateral-dependent loans is measured on the basis of the fair value of the collateral when foreclosure is probable.
Our ACL at December 31, 2022 was $158.4 million. Given the dynamic relationships between economic variables, it is difficult to estimate the impact of a change in any one individual variable on the ACL. To illustrate a hypothetical sensitivity, however, we performed an analysis on the unemployment rate economic variable to evaluate the impact of a change in that assumption over the reasonable and supportable forecast period. If the unemployment rate increased by 100 basis points, the quantitative ACL estimate would increase by $2.9 million and if the unemployment rate were decreased by 100 basis points, the quantitative ACL estimate would decrease by $2.4 million.
Our allowance policy and the judgments, estimates and economic assumptions involved are described in greater detail in the “Allowance for Credit Losses and Unfunded Commitments and Letters of Credit” section of this discussion and in Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.
Business Combinations
The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes prevailing valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Acquisition-relatedMerger-related costs are expensed as incurred.

Valuation and Recoverability of Goodwill
Goodwill represented $765.8$823.2 million of our $14.08$20.27 billion in total assets as of December 31, 2019.2022. The Company has a single reporting unit. We review goodwill for impairment annually during the third quarter,as of July 31, and also test for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of our reporting unit below its carrying amount. Such events and circumstances may include among others: a significant adverse change in legal factors or in the general business climate; significant decline in our stock price and market capitalization; unanticipated competition; the testing for recoverability of a significant asset group within the reporting unit; and an adverse action or assessment by a regulator. Any adverse change in these factors could have a significant impact on the recoverability of goodwill and could have a material impact on our Consolidated Financial Statements.
Under the Intangibles – GoodwillIntangibles-Goodwill and Other topic of the FASB ASC, the testinggoodwill is not amortized but rather is tested for impairment at the reporting unit level on at least an annual basis. The test for impairment requires the Company to compare the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit is less than its carrying value, the difference is the amount of impairment and goodwill is written down to the fair value of the reporting unit. Prior to completing the impairment test, however, the Company may begin with an assessment ofassess qualitative factors to determine ifwhether it is more likely than not that the fair value of athe reporting unit is less than its carrying amount. When required, the goodwill impairment test involves a two-step process. In step one, we would test goodwill for impairment by comparingIf such an assessment indicates the fair value of the reporting unit withis more likely than not greater than its carrying amount. Ifvalue, then the fair value of the reporting unit exceeds the carrying amount of the reporting unit, goodwill isimpairment test need not deemed to be impaired, and no further testing is necessary. If the carrying amount of the reporting unit were to exceed the fair value of the reporting unit, we would perform a second test to measure the amount of impairment loss, if any. To measure the amount of any impairment loss, we would determine the implied fair value of goodwill in the same manner as if the reporting unit were being acquired in a business combination. Specifically, we would allocate the fair value of the reporting unit to all of the assets and liabilities of the reporting unit in a hypothetical calculation that would determine the implied fair value of goodwill. If the implied fair value of goodwill is less than the recorded goodwill, we would record an impairment charge for the difference.completed.
The accounting estimates related to our goodwill require us to make considerable assumptions about fair values.value. Our assumptions regarding fair valuesvalue require significant judgment about economic and industry factors and the growth and earnings prospects of the Bank. Changes in these judgments, either individually or collectively, may have a significant effect on the estimated fair values.value.
Based on the results of the annual goodwill impairment test, we determined that no goodwill impairment charges were required as our single reporting unit’s fair value significantly exceeded its carrying amount. As of December 31, 2019,2022, we determined there were no events or circumstances which would more likely than not reduce the fair value of our reporting unit below its carrying amount.

2022 Financial Summary
Income Statement
Consolidated net income for 20192022 was $194.5$250.2 million, or $2.68$3.20 per diluted common share, compared with net income of $172.9$202.8 million, or $2.36$2.78 per diluted common share in 2018.2021.
Net interest income for 2019 increased 3% to $493.4 million compared to $478.8 million for 2018. Interest income was $530.0 million in 2019, compared to $497.1 million in 2018. The increase was primarily due to income from higher average loan and securities balances and higher rates on loans. Interest expense increased $18.3 million from $18.2 million in 2018, due to higher rates on interest-bearing deposits and higher average FHLB balances.
Provision for loan and lease losses was $3.5 million in 2019, compared to $14.8 million in 2018. The decline in provision expense for 2019 reflects a decrease in both nonaccrual loans and net loan charge-offs.
Noninterest income was $97.2 million for 2019, an increase from $88.3 million for 2018. The increase in 2019 was primarily due to gains on the sales of owned real estate and BOLI benefits.
Noninterest expense increased $5.0 million to $345.5 million for 2019 due primarily to higher compensation and employee benefits and legal and professional fees partially offset by decreases in other noninterest, net cost (benefit) of OREO, regulatory premiums and amortization of intangibles.
Net interest income in 2022 increased 18% to $622.8 million compared to $527.5 million in 2021. Interest income was $646.5 million in 2022, compared to $536.1 million in 2021. The increase was primarily due to higher interest income from loans. Interest expense for 2022 increased $15.1 million to $23.6 million compared to $8.5 million in 2021, due to higher deposit interest expense as a result of higher average rates and increased average balances of FHLB advances.
Provision for credit loss on loans was $2.0 million in 2022, compared to $4.8 million in 2021. The decrease in provision expense for 2022 reflects improving credit quality, the removal of allowance for credit loss on loans transferred to held for sale in connection with the branch divestitures related to our pending merger with Umpqua, a reduction in COVID-19 related reserve impacts and recoveries outpacing charge-offs.
Noninterest income was $99.1 million in 2022, an increase from $94.1 million in 2021. The increase in 2022 was primarily due to a $3.7 million gain from the sale-leaseback of owned real estate, increased deposit account and treasury management fees, card revenue, financial services and trust revenue. This was partially offset by a decrease in mortgage banking revenue.
Noninterest expense in 2022 increased $42.1 million to $402.4 million compared to $360.3 million in 2021. The increase was primarily due to higher compensation and employee benefits and occupancy expense mainly driven by our acquisition of Bank of Commerce Holdings in the fourth quarter of 2021. Higher other noninterest expense, data processing and software, regulatory premiums and merger-related expenses also contributed to the increase from the prior period.

Net Interest Income
Net interest income is the difference between interest income and interest expense. Net interest income on a fully taxable-equivalent basis expressed as a percentage of average total interest-earning assets is referred to as the net interest margin, which represents the average net effective yield on interest-earning assets.

The following table sets forth the average balances of all major categories of interest-earning assets and interest-bearing liabilities, the total dollar amounts of interest income on interest-earning assets and interest expense on interest-bearing liabilities, the average yield earned on interest-earning assets and average cost of interest-bearing liabilities by category and in total, net interest income, net interest spread, net interest margin and the ratio of average interest-earning assets to interest-earninginterest-bearing liabilities:

(1) For tax exempt loans and tax exempt securities,The change in interest not due solely to volume or rate has been allocated in proportion to the absolute dollar amount of our tax equivalent adjustment for 2018 was impacted by the lower federal corporate tax rate. As a result, our tax equivalent adjustments for tax exempt loans and tax exempt securities were $4.7 million and $3.3 million lower, respectively, than they would have been utilizing the prior federal corporate tax rate. This change in federal corporate tax rate negatively impacted our 2018 net interest margin (tax equivalent) by 7 basis points.each.

Incremental accretion income represents the amount of interest income recorded on acquired loans above the contractual rate stated in the individual loan notes. The additional interest income stems from the net discount established at the time these loan portfolios were acquired. The following table shows the impact to interest income of incremental accretion income as well as the net interest margin and operating net interest margin for the periods presented:

Taxable-equivalent net interest income totaled $501.8$631.1 million in 2019,2022, compared with $486.7$535.3 million for 2018.2021. The increase in net interest income during 20192022 resulted from the increase in the size and average rate of the loan and investment securities portfolios as well as the increase in yield on the loan portfolio.

Table of 2018 with 2017Contents
Taxable-equivalent net interest income totaled $486.7 million in 2018, compared with $380.1 million for 2017. The increase in net interest income during 2018 resulted from the increase in the size of the loan and securities portfolios, primarily due to the Pacific Continental acquisition. The increase in net interest income was partially offset by higher interest rates paid on interest-bearing liabilities combined with higher balances of interest-bearing liabilities due to the acquisition.
The Company’s net interest margin (tax equivalent) increased from 4.18% for the year ended December 31, 2017 to 4.33% for the year ended December 31, 2018 due primarily to higher yields on loans as well as higher loan volumes, partially offset by both the rise in rates paid on deposits and other interest-bearing liabilities as well as the balance in these liabilities. The Company’s operating net interest margin (tax equivalent) increased from 4.15% for the year ended December 31, 2017 to 4.30% for 2018 due to higher volumes and rates on loans.
Provision for Loan and LeaseCredit Losses
The Company accounts for the credit risk associated with lending activities through its “ALLL”ACL and “Provisionprovision for loan and leasecredit losses. The provision is the expense recognized in the Consolidated Statements of Income to adjust the allowance to the levelslevel deemed appropriate by management, as determined through its application of the Company’s allowance methodology procedures. For discussion of the methodology used by management in determining the adequacy of the ALLL,ACL, see the “Allowance for Loan and LeaseCredit Losses and Unfunded Commitments and Letters of Credit” and “Critical Accounting Policies” sections of this discussion.

The Company recorded provision expense of $3.5$2.0 million $14.8for credit losses during 2022 compared to a provision expense of $4.8 million for 2021. A provision expense of $77.7 million was recorded in 2020. The decrease in provision expense for 2022 was due to improved credit quality, the removal of allowance for credit loss on loans transferred to held for sale in connection with the branch divestitures related to our pending merger with Umpqua, a reduction in COVID-19 related reserve impacts and $8.6 million in 2019, 2018 and 2017, respectively. Therecoveries outpacing charge-offs. In addition, the provision recorded in 20192022 included management’s ongoing assessment of the credit quality of the Company’s loan portfolio. Factors affecting the provision include net charge-offs, credit quality migration and size and composition of the loan portfolio and changes in the economic environment during the period. See “Allowance for Loan and LeaseCredit Losses and Unfunded Commitments and Letters of Credit” section of this discussion for further information on factors considered by the Company in assessing the credit quality of the loan portfolio and establishing the ALLL.ACL.
Net loan recoveries for the year ended December 31, 2022 were $910 thousand. For the years ended December 31, 2019, 20182021 and 2017,2020, net loan charge-offs amounted to $2.9$978 thousand, and $14.2 million, $7.0 million, and $3.0 million, respectively.

The increase in other noninterest income was dueprimarily related to current year gainsa $3.7 million gain from the sale-leaseback of $6.6 million asowned real estate. The increases in noninterest income were partially offset by a result of the sale of three real estate parcels as well as $3.1 million in BOLI benefits. There were no similar benefits realized in 2018.

Table of 2018 with 2017Contents
The $21.4 million decrease in noninterest income was principally from the $14.0 million gain on sale of the merchant card services portfolio on July 1, 2017. As a result of the merchant card services portfolio sale, we now share with the buyer in merchant services revenue and include such amounts in “Card revenue.” The decrease was also attributable to lower card revenue as we became subject to the interchange fee cap imposed under the Dodd-Frank Act on July 1, 2018, and the change to net presentation of interchange revenue pursuant to the adoption of new revenue recognition accounting guidance, which became effective on January 1, 2018. Specifically, $5.0 million of payment card network expenses for 2018 that would have historically been presented in “other noninterest expense” are now presented in “card revenue.” Partially offsetting these decreases to noninterest income was an increase in deposit account and treasury management fees of $5.7 million, or 19%.

(1) Beginning the first quarter of 2019, B&O taxes were reported separately from other taxes, licenses and fees, which are now reported under “other noninterest expense.” Prior periods have been reclassified to conform to current period presentation.
(2) In the first quarter of 2018, there was a change to net presentation of interchange revenue pursuant to the adoption of new revenue recognition accounting guidance on January 1, 2018. As a result, card revenue for the twelve months ended December 31, 2019 and 2018 includes card network expenses of $4.5 million and $5.0 million, respectively, that would have historically been presented in other noninterest expense.

Comparison of 20192022 with 20182021
Noninterest expense was $345.5$402.4 million in 2019,2022, an increase of $5.0$42.1 million over 2018. Included in noninterest expense were $8.7 million of acquisition-related2021. Merger-related expenses in 2018.the current year were $19.1 million, an increase of $4.6 million over 2021. After removing the effect of acquisition-relatedmerger-related expenses, noninterest expense increased $13.7$37.5 million mainly due to higher compensation and employee benefits stemming from additional personnel costs associated with the Bank of Commerce acquisition and legallower loan origination costs related to the prior year PPP loan production. Higher occupancy expense was also associated with the Bank of Commerce acquisition. In addition, data processing expense and professional fees. These increases were partially offset by decreases in other noninterest and OREO expenses as well as decreases in regulatory premiums and amortization of intangibles. The increases in compensation and employee benefits were driven by increases in salaries, group insurance and other compensation and incentive expenses. The increase in legal and professional fees wasincreased. Other noninterest expense increased mainly due to an increase in professional fees related to our digital initiative strategy.higher net loan expense, travel and entertainment expenses and fraud losses. These increases were partially offset by a decrease in OREO expenses which was driven byprovision recapture for unfunded loan commitments.

The provision (recapture) for unfunded loan commitments, a gain on the salecomponent of OREO in 2019 compared to a loss on the sale of OREO in 2018. Other noninterest expenses decreased due to a recapture of the provision for off-balance sheet reserves recognized in 2019 compared to a provision for off-balance sheet reserves reported in 2018. The reduction in regulatory premiums was due to the utilization of a portion of our FDIC Small Bank Assessment Credit during the last half of 2019 and the decrease in the amortization of intangibles was a result of the amortization of our CDI asset.
Comparison of 2018 with 2017
Noninterest expense was $340.5 million in 2018, an increase of $49.5 million, or 17%, over 2017. Included inother noninterest expense, were $8.7 million of acquisition-related expenses compared to $17.2 million in 2017. After removingare as follows for the effect of acquisition-related expenses, noninterest expense increased $58.0 million due to higher compensation and employee benefits, amortization of intangibles, legal and professional fees, and other expenses. The increases in compensation and employee benefits and amortization of intangibles were driven by increases in salaries, benefits, and payroll taxes and amortization of core deposit intangibles. These increases were primarily due to the Pacific Continental acquisition, as 2018 included the full year of the acquired bank expenses compared to the inclusion of only two months of expenses in 2017. The increase in legal and professional fees was driven mainly by an increase in treasury management and legal fees related to nonperforming loans. Other noninterest expense increased due to increases in software expense and sponsorships and other charitable contributions. These increases were partially offset by a decrease in merchant processing expense. As a result of the 2017 sale of our merchant card services portfolio, we no longer directly incur merchant processing costs.periods indicated:

Income Tax
For the years ended December 31, 2019, 20182022, 2021 and 2017,2020, we recorded income tax provisions of $47.2$67.5 million, $39.0$53.7 million and $65.2$38.1 million, respectively. The effective tax rate was 21% in 2022 and 2021 and 20% in 2019, 18% in 2018 and 37% in 2017. Our effective tax rate for 2019 and 2018 were positively impacted by the Tax Cuts and Jobs Act which was enacted on December 22, 2017. On January 1, 2018, the Tax Cuts and Jobs Act reduced the federal tax rate for corporations from 35% to 21% and changed or limited certain deductions. Our effective tax rate for 2017 was impacted by the re-measurement of our deferred tax assets pursuant to the enactment of the Tax Cuts and Jobs Act. As a result of the lower corporate tax rate, during 2017, we recorded a re-measurement charge of $12.2 million to reduce our deferred tax assets. For 2019 and 2018, our effective tax rates were less than the 21% federal statutory rates, respectively, primarily due to tax-exempt municipal investment securities income, tax-exempt earnings from bank owned life insurance, and income from loans with favorable tax attributes.2020.

Investment Portfolio
We invest in securities to generate revenue for the Company, to manage liquidity while minimizing interest rate risk and to provide collateral for certain public deposits and short-term borrowings. The amortized cost amounts represent the Company’s original cost for the investments, adjusted for accumulated amortization or accretion of any yield adjustments related to the security. The estimated fair values are the amounts we believe the securities could be sold for as of the dates indicated. At December 31, 2019,2022, gross unrealized losses in our debt securities available for sale portfolio were $20.4$694.3 million related to 2881,378 separate available for sale securities. Based on past experience with these types of securities and our own financial performance, we do not currently intend to sell any securities in a loss position nor does available evidence suggest it is more likely than not that management will be required to sell any securities currently in a loss position before the recovery of the amortized cost basis. We review these investments for other-than-temporary impairmentcredit losses on an ongoing basis.
Our investment portfolio increased $578.7 millionAll of the Company’s debt securities held to maturity were issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Therefore, the Company did not record an allowance for credit losses for these securities as of December 31, 2022.
Debt securities available for sale decreased $1.32 billion from the prior year due to purchasesmaturities and repayments of $1.20 billion and $86.2$770.7 million, $706.7 million in net unrealized gainlosses, and premium amortization of $31.0 million, partially offset by purchases of $186.5 million. Debt securities held to maturity decreased by $113.5 million due to maturities and repayments and sales of $685.4$188.4 million and premium amortization of $19.0$22.7 million, partially offset by purchases of $97.7 million.

Activity based stock is stock we are required to purchase and hold in order to obtain an advance or participate in FHLB mortgage programs. The Company’s activity based stock purchase requirement is measured as a percentage of our advance proceeds. At December 31, 2019,2022, the Company held $48.1$48.2 million of FHLB Class B stock, $10.0 million of which was membership stock and the remaining $38.1$38.2 million of which was activity based.

At December 31, 2019, total loans, gross of the ALLL were $8.74 billion compared with $8.39 billion in the prior year, an increase of $352.0 million, or 4.2% from the previous year. The increase in the loan portfolio was the result of organic loan production, partially offset by contractual payments and prepayments. Total loans, net of the ALLL, represented 62% and 63% of total assets at December 31, 2019 and 2018, respectively.
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.
Real Estate Loans: One-to-four family residentialCommercial 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.
Real Estate Commercial Business Loans: Our commercial business lending is directed toward meeting the credit and related deposit and treasury management needs of small to medium sized businesses. Commercial and industrial loans are primarily underwritten based on the identified cash flows of the borrower’s operations and secondarily on the underlying collateral provided by the borrower and/or the strength of the guarantor. The majority of these loans provide financing for working capital and capital expenditures. Loan terms, including, loan maturity, fixed or adjustable interest rate and collateral considerations, are based on factors such as the loan purpose, collateral type and industry and are underwritten on an individual loan basis.
Agriculture Loans: Agricultural lending includes agricultural real estate and production loans and lines of credit within our primary market area. We are committed to our 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 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)service) of 1.2 or better. As noted above, underwriting standards can be influenced by competition and other factors. However, we endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.
One-to-four Family Residential Real Estate Loans: One-to-four family residential loans, including home equity loans and lines of credit, are secured by properties located within our primary market areas and, typically, have loan-to-value ratios of 80% or lower at origination.
Other Consumer Loans:Consumer loans include automobile loans, boat and recreational vehicle financing, home equity and home improvement loans andother 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, Idaho and Idaho.

Purchased Credit Impaired Loans: PCI loans are comprised of loans and loan commitments acquired in connection with the 2011 FDIC-assisted acquisitions of First Heritage Bank and Summit Bank, as well as the 2010 FDIC-assisted acquisitions of Columbia River Bank and American Marine Bank. PCI loans are generally accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). The Company did not acquire any loans accounted for under ASC 310-30 during 2019 or 2018.

Risk Elements
The extension of credit in the form of loans or other credit substitutes to individuals and businesses is one of our principal commerce activities. Our policies, applicable laws, and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies, and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry, type of borrower, and by limiting the aggregation of debt to a single borrower.
In analyzing our existing portfolio, we review our consumer and residential loan portfolios by their performance as a pool of loans, since no single loan is individually significant or judged by its risk rating, size or potential risk of loss. In contrast, the monitoring process for the commercial business, real estate construction, and commercial real estate portfolios includes periodic reviews of individual loans with risk ratings assigned to each loan and performance judged on a loan by loan basis.

We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. In the event that full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan. For additional discussion on our methodology in managing credit risk within our loan portfolio, seeNet unearned acquisition premium (discount): “Allowance for Loan and Lease Losses and Unfunded Commitments and Letters of Credit” section and Note 1 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.

Loan policies, credit quality criteria, portfolio guidelines and other controls are established under the guidance of our Chief Credit Officer and approved, as appropriate, by the board of directors. Credit Administration, together with the management loan committee, has the responsibility for administering the credit approval process. As another part of its control process, we use an internal credit review and examination function to provide reasonable assurance that loans and commitments are made and maintained as prescribed by our credit policies. This includes a review of documentation when the loan is initially extended and subsequent examination to ensure continued performance and proper risk assessment.
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 totaled $33.6 million, or 0.24% of year end assets at December 31, 2019, compared to $60.9 million, or 0.46% of year end assets at December 31, 2018.

Loans are considered impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a TDR. A loan is classified as a TDR when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include interest rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can meet the restructured terms. If the borrower’sperformance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan.
The assessment for impairment occurs when and while such loans are designated as classified per the Company’s internal risk rating system or when and while such loans are on nonaccrual. All nonaccrual loans greater than $500,000 and all TDR loans are considered impaired and analyzed individually on a quarterly basis. Classified loans with an outstanding balance greater than $500,000 are evaluated for potential impairment on a quarterly basis. The Company’s policy is to record cash receipts on impaired loans first as reductions in principal and then as interest income.
The following table summarizes impaired loan financial data at December 31, 2019 and 2018:

Impaired loans with a carrying amount of $32.0 million at December 31, 2019 were subject to specific allocations of ALLL of $461 thousand and charge-offs of $7.2 million during the year. Collateral dependent impaired loans without specific allocations at December 31, 2019 and 2018 either had collateral which exceeded the carrying value of the loans or reflected a partial charge-offprovides additional details related to the market valuenet premium (discount) of collateral (less costs to sell), as of the most recent appraisal date. Restructuredacquired and purchased loans, accruing interest totaled $9.7 million and $15.3 million at December 31, 2019 and 2018, respectively.
When a loan with unique risk characteristics has been identified as being impaired, the amount of impairment will be measured by the Company using discounted cash flows, except when it is determined that the remaining source of repaymentacquisition for the loan is the operation or liquidation of the underlying collateral. In these cases, the current fair value of the collateral, reduced by costs to sell, will be used in place of discounted cash flows. As a final alternative, the observable market price of the debt may be used to assess impairment. Predominately, the Company uses the fair value of collateral approach based upon a reliable valuation.periods indicated:

When a loan secured by real estate migrates to nonperforming and impaired status and it does not have a market valuation less than one year old, the Company secures an updated market valuation by a third-party appraiser that is reviewed by the Company’s on-staff appraiser. Subsequently, the asset will be appraised annually by a third-party appraiser or the Company’s on-staff appraiser. The evaluation may occur more frequently if management determines that there has been increased market deterioration within a specific geographical location. Upon receipt and verification of the market valuation, the Company will record the loan at the lower of cost or market (less costs to sell) by recording a charge-off to the ALLL or by designating a specific reserve in accordance with accounting principles generally accepted in the United States.

Other Real Estate and Other Personal Property Owned: AsTable of December 31, 2019, there was $552 thousand in OREO and OPPO, which was primarily comprised of property from foreclosed real estate loans which decreased $5.5 million from $6.0 million at December 31, 2018. The decrease was primarily driven by $5.7 million in OREO sales. Properties acquired by foreclosure or deed in lieu of foreclosure are transferred to OREO and are recorded at fair value less estimated costs to sell, at the date of transfer of the property. If the carrying value exceeds the fair value at the time of the transfer, the difference is charged to the ALLL. The fair value of the OREO property is based upon current appraisal. Subsequent losses that result from the ongoing periodic valuation of these properties are charged to the net cost of operation of OREO expense in the period in which they are identified. In general, improvements to the OREO are capitalized and holding costs are charged to the net cost of operation of OREO as incurred.Contents
Potential Problem Loans: Potential problem loans are loans which are currently performing and are not on nonaccrual status, restructured or impaired, but about which there are significant doubts as to the borrower’s future ability to comply with repayment terms and which may later be included in nonaccrual, past due, restructured or impaired loans. Potential problem loans totaled $72.5 million at year end 2019, compared to $26.6 million at year end 2018. The increase in potential problem loans in 2019 was driven by a large commercial business loan and a large income property multifamily loan.
Allowance for Loan and LeaseCredit Losses and Unfunded Commitments and Letters of Credit
The ALLLACL is an accounting estimate of incurredexpected credit losses in our loan portfolio at the balance sheet date. The provision for loan and leasecredit losses is the expense recognized in the Consolidated Statements of Income to adjust the allowanceACL to the levels deemed appropriate by management, as measured by the Company’s credit loss estimation methodologies. The ALLLallowance for unfunded commitments and letters of credit is maintained at a level believed by management to be sufficient to absorb estimated probableexpected losses related to these unfunded credit facilities at the balance sheet date.

(1)Excludes loans held for sale.

At December 31, 2019, our ALLL was $84.0 million, or 0.96% of total loans (excluding loans held for sale). This compares with an allowance of $83.4 million, or 0.99% of total loans (excluding loans held for sale) at December 31, 2018.
We have used the same methodology for ALLL calculations during 2019, 2018 and 2017. Adjustments to the percentages of the ALLL allocated to loan categories are made based on trends with respect to delinquencies and problem loans within each loan class. The Company reviews the ALLL quantitative and qualitative methodology on a quarterly basis and makes adjustments when appropriate. We continue to make revisions to our ALLL as necessary to maintain adequate reserves. The Company carefully monitors the loan portfolio and continues to emphasize the importance of credit quality while continuously strengthening loan monitoring systems and controls.

Borrowings
Borrowed funds provide an additional source of funding for loan growth. Our borrowed funds consist primarily of borrowings from the FHLB andadvances, FRB borrowings, securities sold under agreements to repurchase, subordinated debentures, junior subordinated debentures and a revolving line of credit. FHLB advances and FRB borrowings are secured by our loan portfolio and investment securities. Securities sold under agreements to repurchase are secured by investment securities. Subordinated debentures and junior subordinated debentures are unsecured and the revolving line of credit is available, if necessary, and requires the Company to comply with certain covenants including those related to asset quality and capital levels. For additional information on our borrowings, see Notes 12, 13, 1414, 15, and 15,16 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.
Off-Balance Sheet Arrangements
In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount reflected in the Consolidated Balance Sheets.
46

Exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company evaluates each client’s creditworthiness on a case-by-case basis.

Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
The Company had off-balance sheet loan commitments aggregating $2.67$3.91 billion and $2.62$3.50 billion at December 31, 20192022 and 2018,2021, respectively. Standby letters of credit were $25.7$33.2 million at December 31, 2019,2022, a decrease from $28.3$36.0 million at December 31, 2018. In addition, there were no commitments under commercial letters of credit used to facilitate customers’ trade transactions and other off-balance sheet liabilities at December 31, 2019 and 2018.2021.

(1) In the banking industry, interest-bearing obligations are principally used to fund interest-earning assets. As such, interest charges on contractual obligations were excluded from reported amounts, as the potential cash outflows would have corresponding cash inflows from interest-earning assets.
For additional information regarding our contractual obligations, see Notes 10, 11, 12, 13 and 14 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.
Liquidity and Sources of Funds
In general, our primary sources of funds are net income, loan repayments, maturities and principal payments on investment securities, customer deposits, advances from the FHLB, andborrowings from the FRB, securities repurchase agreements, subordinated debentures, junior subordinated debentures and a revolving line of credit available, if necessary. These funds are used to make loans, purchase investments, meet deposit withdrawals and maturing liabilities and cover operational expenses. Scheduled loan repayments and client deposits have proven to be a relatively stable source of funds while other deposit inflows and unscheduled loan prepayments are influenced by interest rate levels, competition and general economic conditions. We manage liquidity through monitoring sources and uses of funds on a daily basis and had unused credit lines with the FHLB and the FRB of $1.96$1.92 billion and $209.1$198.8 million, respectively, at December 31, 2019,2022, that are available to us as a supplemental funding source. The holding company’s sources of funds are dividends from its banking subsidiary which are used to fund dividends to shareholders, purchase treasury shares and cover operating expenses.
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, depositarydepository shares, purchase contracts, units and warrants in one or more offerings. From time to time, we may seek to raise additional capital in order to meet our commitments, fund our business needs and future growth, and supplement our regulatory capital. 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 future offering.

Our shareholders’ equity increased__________
(1) In the banking industry, interest-bearing obligations are principally used to $2.16 billionfund interest-earning assets. As such, interest charges on contractual obligations were excluded from reported amounts, as the potential cash outflows would have corresponding cash inflows from interest-earning assets.
(2) Includes $585.1 million of deposits held for sale at December 31, 2022.
For additional information regarding our contractual obligations, see Notes 201910, from $2.03 billion11 at December 31,, 201812. Shareholders’ equity was, 15.34%13, 14 and 15.53%15 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this report.

Capital
Our shareholders’ equity decreased to $2.21 billion at December 31, 2022, from $2.59 billion at December 31, 2021. This decrease was primarily a result of market value decreases in our available for sale securities portfolio, partially offset by higher retained earnings. Shareholders’ equity was 10.92% and 12.36% of total assets at December 31, 20192022 and 2018,2021, respectively. Dividends per common share were $1.40$1.20 and $1.14, for the years ended December 31, 20192022 and 2018,2021, respectively.
Regulatory Capital. In July 2013, the federal bank regulators approvedWe are subject to the Capital Rules (as discussed in “Item 1. Business—Supervision and Regulation—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.
Basel III also introduced a new capital conservation buffer, composed entirely of CET1, on top of the minimum risk- weighted asset ratios. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of CET1 to risk-weighted assets, Tier 1 to risk-weighted assets or total capital to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall.Act. The Company and the Bank are required to maintain such additionala capital conservation buffer of 2.5% of CET1, effectively resulting in minimum ratios of (i) CET1 to risk-weighted assets of at least 7%, (ii) Tier 1 capital to risk-weighted assets of at least 8.5%, and (iii) total capital to risk-weighted assets of at least 10.5%. The Company and the Bank met all such capital requirements as of December 31, 2019.2022.
In addition, FDIC regulations set forth the qualifications necessary for a bank to be classified as “well-capitalized” (as discussed in “Item 1. Business—Supervision and Regulation—Prompt Corrective Action Framework”), 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 December 31, 20192022 and 2018.2021.
As part of their 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, certain capital ratios and amounts as of December 31, 2022 exclude the impact of the increased allowance for credit losses related to the adoption of CECL.

Stock Repurchase Program
On November 14, 2018, the 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. On October 23, 2019, the board of directors extended the duration of the stock repurchase program through early May 2020. The Company intends to 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 1.5 million shares of common stock totaling $50.8 million for the year ended December 31, 2019.

Applicable federal and Washington state regulations restrict capital distributions, including dividends, by the Company’s banking subsidiary. Such restrictions are tied to the institution’s capital levels after giving effect to distributions. Our ability to pay cash dividends is substantially dependent upon receipt of dividends from the Bank. In addition, the payment of cash dividends is subject to Federal regulatory requirements for capital levels and other restrictions. In this regard, current guidance from the Federal Reserve provides, among other things, that dividends per share on the Company’s common stock generally should not exceed EPS, measured over the previous four fiscal quarters. Federal Reserve policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company’s capital structure.

Non-GAAP Financial Measures
In addition to the capital ratios defined by banking regulators, the Company considers various measures when evaluating capital utilization and adequacy, including:
Tangible common equity to tangible assets, and
Tangible common equity to risk-weighted assets.
The Company believes these measures are useful because they reflect the level of capital available to withstand unexpected market conditions. Additionally, presentation of these measures allows readers to compare certain aspects of the Company’s capitalization to other organizations. These ratios differ from capital measures defined by banking regulators principally in that the numerator excludes shareholders’ equity associated with preferred securities, the nature and extent of which varies across organizations. Additionally, these measures present capital adequacy inclusive and exclusive of accumulated other comprehensive income. These calculations are intended to complement the capital ratios defined by banking regulators for both absolute and comparative purposes.
Because GAAP in the United States of America dodoes not include capital ratio measures, the Company believes there are no comparable GAAP financial measures to these tangible common equity ratios. The following table reconciles the Company’s calculation of these measures to amounts reported under GAAP.

Despite the importance of these measures to the Company, there are no standardized definitions for them 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 Company also considers operating net interest margin (tax equivalent) to be a useful measurement as it 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 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.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Sensitivity
We are exposed to interest rate risk, which is the risk that changes in prevailing interest rates will adversely affect assets, liabilities, capital, income and expenses at different times or in different amounts. Generally, there are four sources of interest rate risk as described below:
Repricing risk—Repricing risk is the risk of adverse consequences from a change in interest rates that arises because of differences in the timing of when those interest rate changes affect an institution’s assets and liabilities.
Basis risk—Basis risk is the risk of adverse consequence resulting from unequal changes in the spread between two or more rates for different instruments with the same maturity.
Yield curve risk—Yield curve risk is the risk of adverse consequence resulting from unequal changes in the spread between two or more rates for different maturities for the same instrument.
Option risk—In banking, option risks are known as borrower options to prepay loans and depositor options to make deposits, withdrawals, and early redemptions. Option risk arises whenever bank products give customers the right, but not the obligation, to alter the quantity or the timing of cash flows. Option risk is also present in the investment portfolio as mortgage-backed securities could prepay or callable bonds could be called.
An Asset/Liability Management Committee is responsible for developing, monitoring and reviewing asset/liability processes, interest rate risk exposures, strategies and tactics and reporting to the board of directors. It is the responsibility of the board of directors to establish policies and interest rate limits and approve these policies and interest rate limits annually. It is the responsibility of management to execute the approved policies, develop and implement risk management strategies and to report to the board of directors on a regular basis. We maintain an asset/liability management policy that provides guidelines for controlling exposure to interest rate risk. The policy guidelines direct management to assess the impact of changes in interest rates upon both earnings and capital. The guidelines establish limits for interest rate risk sensitivity.
Interest Rate Risk Sensitivity
AWe use 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 may not be realized and, as a result, actual results will differ from our projections. In addition, variances in the timing, magnitude and frequency of interest rate changes, overall market conditions including volumes and pricing, changes in management strategies, among other factors will also result in variances between the projected and actual results.
BasedThe following table summarizes the expected impact on net interest income over a one or two year period if interest rates gradually increased or decreased during the first year, based on the results of the simulation model as of December 31, 2019, we would expect decreases in2022:

The following table summarizes the expected impact on net interest income of $2.9 million and $22.4 million inover a one or two year one and year two, respectively,period if interest rates graduallyinstantaneously increased or decreased, based on the results of the simulation model as of December 31, 2022:

-100$(19,518)(3.01)%$(41,788)(6.09)%
51

The projections are based on the current interest rate environment and a stable balance sheet. Market interest rates increased substantially during 2022 with short-term interest rates increasing substantially more than long-term interest rates resulting in an inverted yield curve at year end. Due to the rise in short-term interest rates, the majority of our floating rate loans are no longer constrained by interest rate floors. However our ability to reprice deposits downward is still limited given our low cost of funds.
Our asset sensitivity decreased since the prior quarter and year ends mainly due to the decline in deposits during the quarter and the corresponding increase in short-term FHLB borrowings. Balance sheet projections for this analysis include the sales of branches and a corresponding increase in borrowings. The net impact of the change in funding mix was a decrease from current rates by 100 basis points. We would expect an increase in the duration of funding, which reduced the net interest income benefits of $517 thousand and $21.4 million in year one and year two, respectively, ifrising interest rates gradually increase from currentbut also reduced our exposure to falling interest rates. Prudent management of deposit rates by 200 basis points.and balances will be the key driver in realizing the projected asset sensitivity.
Net interest income sensitivity excludes the amortization of premiums, discounts and deferred fees on the existing loan portfolio although the amortization of the collar is included in loan interest income.
On January 23, 2019, the Company entered into an interest rate collar derivative transaction with a $500.0 million notional based on one month1-month LIBOR. In October 2020, the collar was terminated and resulted in a $34.4 million realized gain that was recorded in accumulated other comprehensive income, net of deferred income taxes. The Company has designated this as a cash flow hedge. This transaction was enteredgain will amortize into to minimize the decrease in net interest income ifthrough February 2024, which is in line with the initial term of the interest rates decline overrate collar. The gain will be amortized in this manner as long as the next five years.cash flows pertaining to the hedged item are expected to occur.
The analysis of an institution’s interest rate gap (the difference between the repricing of interest-earning assets and interest-bearing liabilities during a given period of time) is one standard tool for the measurement of the exposure to interest rate risk. We believe that because interest rate gap analysis does not address all factors that can affect earnings performance, it should be used in conjunction with other methods of evaluating interest rate risk.
The table on the following page sets forth the estimated maturity or repricing, and the resulting interest rate gap of our interest-earning assets and interest-bearing liabilities at December 31, 2019.2022. The amounts in the table are derived from our internal data and are based upon regulatorySEC reporting formats. Therefore, they may not be consistent with financial information appearing elsewhere herein that has been prepared in accordance with accounting principles generally accepted in the United States.

The estimates for net interest income sensitivity and interest rate gap could be significantly affected by external factors such as changes in prepayment assumptions, early withdrawal of deposits and competition. For example, although certain assets and liabilities may have similar maturities or periods to repricing, they may react in different degrees to changes in market interest rates. Also, the interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while other types may lag changes in market interest rates.
Additionally, certain assets, such as adjustable-rate mortgages, have features that restrict changes in the interest rates of such assets both on a short-term basis and over the lives of such assets. Further, in the event of a change in market interest rates, prepayment and early withdrawal levels could deviate significantly from those assumed in calculating the tables. Finally, the ability of many borrowers to service their adjustable-rate debt may decrease in the event of a substantial increase in market interest rates.

Impact of Inflation and Changing Prices
The impact of inflation on our operations is increased operating costs. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates generally have a more significant impact on a financial institution’s performance than the effect of general levels of inflation. Although interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services, increases in inflation generally have resulted in increased interest rates.

In anticipation of the discontinuance of LIBOR, managementManagement has assessed thediscontinued use of LIBOR in its loan portfolio,new contracts, including loans, investment securities and interest rate derivatives and is evaluating the impact that the discontinuance of LIBOR may have on the Company.derivatives. Current actions include the implementation of loan substitute language for new and renewedlegacy LIBOR-based loans to transition to SOFR before June 2023, at which point LIBOR based loans.  We are considering the use of other indexeswill no longer be an option for some of our consumer loans. We are in discussions with our counterparties and tracking industry developmentsColumbia Bank to follow the form and likely timing of the LIBOR transition. We are working on a plan for fulfilling our loan collateral needs with an alternative rate index as the transition date becomes known.use.

Allowance for Loan and LeaseCredit Losses - Refer to Notes 1 5, and 6 to the financial statements
Critical Audit Matter Description
The Company estimates its allowance for loan and lease losses (the “allowance”) is an accounting estimate of incurred credit losses in(ACL) using information derived from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Specifically, the Company’sCompany measures reserves on a collective (pool) basis for all loan portfolio at the balance sheet date. For loans collectively evaluated for impairment, management estimates the allowance with a formula-based model using loss experience over a historical time period that is segmented by loan poolsclasses with similar risk characteristics. Management also considers qualitative factors to ensurecharacteristics, using a quantitative discounted cash flows model that the allowance reflects inherent losses inis then qualitatively adjusted for large loan concentrations, policy exemptions granted, and other factors. The quantitative 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 the loan portfolio.classes utilize regression models to calculate probability of defaults, in which macroeconomic factors are correlated to historical quarterly defaults. The magnitudeCompany utilizes an 18-month forecast for the macroeconomic factors, after which the probability of default reverts to its historical mean using a straight-line basis. As of December 31, 2022, the ACL was $158.4 million.
Significant management judgments are required in determining whether, and to what extent, qualitative adjustments for each portfolio loan class are required and the selection of the qualitative allowance is limited to the maximum loss experience over the historical time period.
reasonable and supportable forecasts of future economic conditions. The qualitative factors capture inherent losses which are not derived from the formula- based model. The most significant qualitative factors relate to changes in economic and business conditions, concentration of credit, loss and recovery trends, nature and volumesubjectivity of the portfoliojudgments made in selecting qualitative adjustments and trends in problem, delinquent and non-accrual loans. These qualitativethe forecasts for the macroeconomic factors have a high degree of subjectivity and changes in any of these factors may have a significant impact on the allowance.remains elevated due to continued economic volatility.
Given the size of the loan portfolio and the subjective nature of estimating the ACL, particularly the estimate of qualitative adjustments and judgment applied by management in determiningselection of forecasts for the most significant qualitativemacroeconomic factors, auditing the allowance for loan and lease losses attributable to such qualitative factors requiredACL involved a high degree of auditor judgmentjudgement requiring significant effort and an increased extent of effort, which included the need to useinvolve credit specialists to appropriately evaluate the account.

specialists.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the allowance attributable toACL for the significant qualitative loss factorsloan portfolio, included the following, among others:

We tested the design and operating effectiveness of controls over the Company’sexecution and monitoring of the quantitative model, selection of the forecast, determination of qualitative adjustments to the modeled reserves and the overall calculation and disclosure of the ACL.
We evaluated the reasonableness of the quantitative discounted cash flows model and related assumptions, assessed the reasonableness of the design and logic of the model, tested the accuracy of the data input into the model, and tested the mathematical accuracy of the model’s calculations.
We evaluated the reasonableness of management’s assessment, determination, and application of the qualitative factors,framework used to determine adjustments to the modeled reserves and tested the mathematical accuracy of the qualitative adjustments.
We used credit specialists to assist us in evaluating the quantitative discounted cash flows model and the framework for certain qualitative adjustments to that model.
We evaluated the reasonableness of the Company’s macroeconomic assumptions and judgments in estimating future credit losses, including the classificationselection of forecasted macroeconomic assumptions and segmentationconsiderations of the loan balancesalternative forecasted macroeconomic scenarios. This included obtaining independent macroeconomic forecasts and management’s review of the relevant factors considered.evaluating any contradictory evidence.
We tested the mathematical accuracy of the modelmacroeconomic factors selected and the data used as inputs in the determination of qualitative factors.
With the assistance of credit specialists, we evaluated the appropriateness of the qualitative framework.
We performed statistical analysis to determine if the primary factors considered by management in the determination of the qualitative factors are appropriate indicators of credit losses.
We evaluated the change and magnitude of the qualitative factors compared to the prior year, as well as the total amount of the allowance attributable to the qualitative factors as of year-end.
We compared previous years’ allowance with subsequent charge offs; compared credit ratios to peer banks; and performed a credit trend analysis.

Adoption of Allowance for Credit Losses (ASC 326) - Refer to Note 1 to the financial statements
Critical Audit Matter Description
In accordance with Accounting Standards Update (the “ASU”) 2016-13, the Company is required to adopt Accounting Standards Codification (“ASC”) 326 as of January 1, 2020. The Company disclosed the estimated financial statement impact of adoption within Note 1. The allowance for credit losses (the “ACL”) is an accounting estimate of expected credit losses over the contractual life of assets carried at amortized cost within the Company’s loan portfolio at the balance sheet date. The ASU requires a financial asset (or a group of financial assets) measured at amortized cost to be presented at the net amount expected to be collected. The ACL is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset.

The quantitative allowance is calculated using a discounted cash flow approach with a probability of default methodology. The probability of default is an assumption derived from a regression model which determines the relationship between historical losses and certain economic variables. The Company determines a reasonable and supportable forecast and applies such forecast to the model to determine losses over the forecast period. Following the forecast period, the economic variables used to calculate the probability of default reverts to a historical average. Other assumptions relevant tocalculations, including evaluating the discounted cash flow model to derivemagnitude of change in the quantitative allowance include the loss given default, which is the estimate of loss for a defaulted loan, and the discount rate appliedattributable to future cash flows. The model calculates the net present value of each loan using both the contractual and expected cash flows, respectively.
We identified the disclosure of the impact of adoption of ASC 326 as a critical audit matter as the model methodology and probability of default assumption are complex and the procedures performed involved a high degree of auditor judgment and required significant effort, including the need to involve credit specialists.
How the Critical Audit Matter Was Addressedchanges in the Auditselected macroeconomic forecasts.
We tested the design and operating effectiveness of controls over the ACL model, including the reconciliation of loan level inputs to the core loan system and to the general ledger.
With the assistance of specialists, we evaluated the appropriateness of the loan segmentation.
We tested the mathematical accuracy of the regression models and the historical loss information, charge-offs and events of default used to calculate the regression models.
With the assistance of specialists, we evaluated the methodology and tested the mathematical accuracy of the model utilizing significant inputs and the reasonable and supportable forecasts of economic variables.
We evaluated management’s reasonable and supportable forecast of economic variables by comparing forecasts to relevant external market data and other forecasts used by management.
We tested the mathematical accuracy and the historical data used to calculate the economic variable reversion to the mean and historical average.
We tested the mathematical accuracy of the discounted cash flow model at a loan level.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the Years Ended December 31, 2022, 2021 and 2020
1.2019, 2018 and 2017Summary of Significant Accounting Policies
1.Summary of Significant Accounting Policies and Reclassifications
Organization
Columbia Banking System, Inc. (the “Corporation,” “we,” “our,” “Columbia” or the “Company”) is the holding company for Columbia State Bank (“Columbia Bank” or the “Bank”) and Columbia Trust Company (“Columbia Trust”). The Bank provides a full range of financial services through 146152 branch locations, including 7167 in the State of Washington, 6159 in Oregon, 15 in Idaho and 1411 in Idaho.California. Columbia Trust provides fiduciary, agency, trust and related services, and life insurance products. Because the Bank comprises substantially all of the business of the Corporation, references to the “Company” mean the Corporation, the Bank and Columbia Trust together. The Corporation is approved as a bank holding company pursuant to the Gramm-Leach-Bliley Act of 1999.
Basis of Presentation
The Company’s accounting and reporting policies conform to GAAP and practices in the financial services industry. To prepare the financial statements in conformity with GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and income and expenses during the reporting period. Circumstances and events that differ significantly from those underlying our estimates and assumptions could cause actual financial results to differ from our estimates. The most significant estimates included in the financial statements relate to the ALLL,ACL, business combinations and goodwill impairment.
The Company has applied its accounting policies and estimation methods consistently in all periods presented in these financial statements (to the periods in which they applied), with the exception of our lease accounting under ASC 842, which was adopted prospectively, beginning in 2019.
Consolidation
The Consolidated Financial Statements of the Company include the accounts of the Corporation and its subsidiaries, including the Bank and Columbia Trust. Intercompany balances and transactions have been eliminated in consolidation.
Cash and cash equivalents
Cash and cash equivalents include cash and due from banks, and interest-bearing balances due from correspondent banks and the FRB. Cash equivalents have a maturity of 90 days or less at the time of purchase.
Securities
SecuritiesDebt securities are classified based on management’s intention on the date of purchase. AllThe Company has debt securities that are classified as available for saleAFS and are presented at fair value.value and debt securities classified as HTM that are presented at amortized cost. Realized gains or losses on sales of debt securities AFS, determined on the basis of the cost of specific securities sold, are included in earnings. Unrealized gains or losses on debt securities available for saleAFS are excluded from net income but are included as separate components ofin other comprehensive income as a separate component of shareholders' equity, net of taxes.tax. Purchase premiums or discounts on debt securities available for saleAFS are amortized or accreted into income using the interest method over the terms of the individual securities.
The Company performs a quarterly assessment to determine whether a decline in fair value below amortized cost is other-than-temporary.exists. Amortized cost includes adjustments made to the cost of an investment for accretion, amortization, collection of cash and previous other-than-temporary impairmentcredit losses recognized in earnings. Other-than-temporary impairment exists when
When the fair value of an AFS debt security falls below the amortized cost basis, it is evaluated to determine if any of the decline in value is attributable to credit loss. Decreases in fair value attributable to credit loss would be recorded directly to earnings with a corresponding allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves the allowance would be reversed up to a maximum of the previously recorded credit losses. If the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be unable to recover the entire amortized cost basis of the security.
In performing the quarterly assessment for debt securities, management considers whether or not the Company expects to recover the entire amortized cost basis of the security. In addition, management also considers whether it is more likely than not that it will not have to sell the security before recovery of its cost basis. If the Company intends to sell a security or it is more likely than not it will be required to sell a security prior to recovery of its cost basis, the entire amount of impairment is recognized in earnings. If the Company does not intend to sell the security or it is not more likely than not it will be required to sell the security prior to recovery of itsrecovering the amortized cost basis, the credit loss component of impairment isentire fair value adjustment would be immediately recognized in earnings and impairment associated with non-credit factors, such as market liquidity, is recognized in “Other comprehensive income (loss), netno corresponding allowance for credit losses.

Our equity securities currently consist of Visa Class B restricted stock which do not have readily determinable fair values. These securities are accounted for at cost basis of the security and the present value of cash flows expected to be collected, discounted at the security’s effective interest rate at the date of acquisition. The cost basis of an other-than-temporarily impaired security is written down by the amount of impairment recognized in earnings. The new cost basis is not adjusted for subsequent recoveries in fair value. However, the difference between the new amortized cost basis and the cash flows expected to be collected is accreted as interest income. The total other-than-temporaryminus impairment, if any, is presentedplus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. Any adjustments to the carrying value of these investments are recorded in Investment securities gains (losses), net in the Consolidated Statements of Income with a reduction for the amount of other-than-temporary impairment that is recognized in “Other Comprehensive Income,” if any.Income.

Realized gains or losses on sales of securities available for sale are recorded using the specific identification method.
Federal Home Loan Bank Stock
The Company holds shares of Class B stock issued by the FHLB, which has been designated as FHLB membership stock or FHLB activity based stock in accordance with the capital plan of the FHLB. Membership stock is stock we are required to purchase and hold as a condition of membership in the FHLB. The Company’s membership stock purchase requirement is measured as a percentage of our year end assets, subject to a $10 million cap. Class B stock may be redeemed, subject to certain limitations, on five years’ written notice to the FHLB. Activity based stock is stock we are required to purchase and hold in order to obtain an advance or participate in FHLB mortgage programs. The Company’s activity based stock purchase requirement is measured as a percentage of our advance proceeds. Our FHLB stock is carried at par value because the shares are issued, transferred, redeemed, and repurchased by the FHLB at a par value of $100. The FHLB stock is subject to recoverability testing per the Financial Services-Depository and Lending topic of the FASB ASC.
Loans held for sale
MortgageOne-to-four family residential real estate loans originated with the intent to be sold in the secondary market are considered held for salesale. One-to-four family residential real estate loans under best efforts delivery commitments are carried at the lower of amortized cost or fair value. There are no economic hedges on these loans. Due to the short period of time between the origination and sale of these loans, the carrying amount of these loans approximates fair value. For one-to-four family residential real estate loans under mandatory delivery commitments, the Company has elected to account for these loans at fair value. The use of the fair value option allows the change in the fair value of the loans to more effectively offset the change in the fair value of derivative instruments that are used as economic hedges for these loans held for sale. Loan origination fees and direct origination costs are recognized immediately in net income. Interest income on loans held for sale approximatesis included in interest income in the Consolidated Statements of Income and recognized when earned. Loans held for sale are placed on nonaccrual in a manner consistent with loans held for investment. The Company recognizes a gain or loss on the sale of loans when the sales criteria for derecognition are met. See Note 22. "Fair Value Accounting and Measurement” for additional information on loans held for sale.
In addition, loans related to the branch divestitures in connection with our merger with Umpqua were reclassified as held for sale at December 31, 2022. These loans are carried at the lower of amortized cost or fair values.value.
Loans
Loans excluding PCI loans, are generally carried at the unpaid principal balance, net of purchase premiums, purchase discounts and net deferred loan fees. Net deferred loan fees include nonrefundable loan origination fees less direct loan origination costs. Net deferred loan fees, purchase premiums and purchase discounts are amortized into interest income using either the interest method or straight-line method over the terms of the loans, adjusted for actual prepayments. The interest method is used for all loans except revolving loans, for which the straight-line method is used. Interest income is accrued as earned. Fees related to lending activities, other than the origination or purchase of loans, are recognized as noninterest income during the period the related services are performed.
Nonaccrual loans—Loans are placed on nonaccrual status when a loan becomes contractually past due 90 days with respect to interest or principal unless the loan is both well secured and in the process of collection, or if full collection of interest or principal becomes uncertain. When a loan is placed on nonaccrual status, any accrued and unpaid interest receivable is reversed and the amortization of net deferred loan fees, premiums and discounts ceases. The interest payments received on nonaccrual loans are generally accounted for on the cost-recovery method whereby the interest payment is applied to the principal balances. Loans may be returned to accrual status when improvements in credit quality eliminate the doubt as to the full collectability of both interest and principal and a period of sustained performance has occurred.
ImpairedRestructured loans—Loans are considered impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a TDR. The assessment for impairment occurs when and while such loans are designated as classified per the Company’s internal risk rating system or when and while such loans are on nonaccrual. All nonaccrual loans greater than $500,000 and all TDR loans are considered impaired and analyzed individually on a quarterly basis. Classified loans with an outstanding balance greater than $500,000 are evaluated for potential impairment on a quarterly basis.
Restructured Loans—A loan is classified as a TDR when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include interest rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a period of six months to demonstrate that the borrower can meet the restructured terms. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan.

In situations where such loans have similar risk characteristics, loans are aggregated into pools to estimate cash flows. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. Expected cash flows at the acquisition date in excess of the fair value of loans are considered to be accretable yield, which is recognized as interest income over the life of the loan pool using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable. Subsequent to the acquisition date, any increases in cash flow over those expected at purchase date in excess of fair value are recorded as interest income prospectively. Any subsequent decreases in cash flow over those expected at purchase date due to credit deterioration are recognized by recording an ALLL on PCI loans. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount.
Unfunded loan commitments—Unfunded commitments are generally related to providing credit facilities to clients of the Bank and are not actively traded financial instruments. These unfunded commitments are disclosed as financial instruments with off-balance sheet risk in Note 18,19, “Commitments and Contingent Liabilities.”
Allowance for Loan and Lease Losses
The ALLL is an accounting estimate of incurred credit losses in our loan portfolio at the balance sheet date. The provision for loan and lease losses is the expense recognized in the Consolidated Statements of Income to adjust the allowance to the levels deemed appropriate by management, as measured by the Company’s credit loss estimation methodologies.
Loans Collectively Evaluated for Impairment—This measure of estimated credit losses is based upon the loss experience over a historical base period adjusted for a loss emergence period. The loss emergence period is an estimate of the period that it takes, on average, for us to identify the amount of loss incurred for a loan that has suffered a loss-causing event. Management then considers the effects of the following qualitative factors to ensure our allowance reflects the inherent losses in the loan portfolio:
Economic and business conditions;
Concentration of credit;
Lending management and staff;
Lending policies and procedures;
Loss and recovery trends;
Nature and volume of the portfolio;
Trends in problem loans, loan delinquencies and nonaccrual loans;
Quality of internal loan review; and
External factors.
These qualitative factors have a high degree of subjectivity and changes in any of the factors could have a significant impact on our calculation of the allowance. The qualitative adjustment by loan segment is based upon management's assessment of inherent losses within a range between the weighted historical loss factor by segment and the maximum consecutive quarterly losses in the relevant loss emergence period by segment over the historical base period.
Loan and lease losses are charged against the allowance when management believes the collectability of a loan balance is unlikely. Subsequent recoveries, if any, are credited to the allowance.
Loans Individually Evaluated for Impairment—This measure of estimated credit losses begins if, based upon current information and events, we believe it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement or when a loan has been modified in a TDR. When a loan has been identified as impaired, the amount of impairment will be measured using discounted cash flows, except when it is determined that the remaining source of repayment for the loan is the operation or liquidation of the underlying collateral. In these cases, the current fair value of the collateral, reduced by costs to sell, will be used in place of discounted cash flows. As a final alternative, the observable market price of the loan may be used to assess impairment. The Company predominately uses the fair value of collateral approach based upon a reliable valuation. When the measurement of the impaired loan is less than the recorded amount of the loan, an impairment is recognized by recording a charge-off to the allowance or by designating a specific reserve.

Purchased Credit Impaired Loans—The Company updates its cash flow projections for PCI loans accounted for under ASC 310-30 on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that is used to estimate the probability of a loan pool transitioning into a particular delinquency state given its delinquency state at the re-measurement date. Loss severity factors are based upon either actual charge-off data within the loan pools or industry averages, and recovery lags are based upon the collateral within the loan pools.
Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized by recording a provision for loan losses. See “Purchased Credit Impaired Loans” under “Loans” for further discussion.
Unfunded Commitments and Letters of Credit—The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded commitments is included in “Other liabilities” on the Consolidated Balance Sheets, with changes to the balance charged against noninterest expense.
Adoption of Allowance for Credit Losses - ASC 326
In accordance with ASU 2016-13, the Company was required to adopt ASC 326 as of January 1, 2020. The allowance for credit losses under ASC 326 is an accounting estimate of expected losses over the contractual life of assets carried at amortized cost within the Company’s loan portfolio at the balance sheet date. The ASU requires a financial assetFinancial assets (or group of financial assets) measured at amortized cost tomust be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset.
The quantitative allowance is calculated using a discounted cash flowDCF approach with a probability of default methodology. The probability of default is an assumption derived from regression models which determines the relationship between historical defaults and certain economic variables. The Company determines a reasonable and supportable forecast and applies that forecast to the regression model to determine defaults over the forecast period. The Company leverages economic projections from an independent third-party provider on a quarterly basis that are vetted by the Company through quantifiable analysis and comparisons are evaluated by a committee before a final scenario is determined for the 18 month reasonable and supportable forecast period used by the Company. Following the forecast period, the economic variables used to calculate the probability of default revertreverts to its historical mean using a straight-line basis constructed on each macroeconomic factor’s absolute historical average.quarterly change at a constant rate. Other assumptions relevant to the discounted cash flow model to derive the quantitative allowance include the loss given default, which is the estimate of loss for a defaulted loan, and the discount rate applied to future cash flows. The DCF model calculates the net present value of each loan using both the contractual and expected cash flows, respectively.
In addition to the quantitative portion of the allowance for credit losses, the Company also considers the effects of the following qualitative factors in its calculation of expected losses in the loan portfolio:
Economic and business conditions;
Concentration of credit;
Lending management and staff;
Lending policies and procedures;
Loss and recovery trends;
Nature and volume of the portfolio;
Trends in problem loans, loan delinquencies and nonaccrual loans;
Quality of internal loan review; and
External factors.Other external factors such as the effect of economic stimulus and loan modification programs.
TheseThe qualitative factors arefactor methodology is based inon quantitative factorsmetrics, but also includeincludes a high degree of subjectivity and changes in any of the factorsmetrics could have a significant impact on our calculation of the allowance.
Loans for which repayment is expected to be provided substantially through the operation or sale of collateral are considered collateral-dependent. The allowance for credit losses for collateral-dependent loans is measured on the basis of the fair value of the collateral when foreclosure is probable.

Unfunded Commitments and Letters of Credit—The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amounts. Expected credit losses are calculated based on the likelihood that funding will occur and an estimate of the amount that will be funded using recent utilization rates, current utilization and the Company’s quantitative ACL rate. The allowance for unfunded commitments is included in “Other liabilities” on the Consolidated Balance Sheets, with changes to the balance charged against noninterest expense.
Premises and Equipment
Land, buildings, leasehold improvements and equipment are stated at cost less accumulated depreciation and amortization. Gains or losses on dispositions are reflected in current operations. Expenditures for improvements and major renewals are capitalized, and ordinary maintenance, repairs and small purchases are charged to “Occupancy” expense in the Consolidated Statements of Income. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets.
64

The ranges of useful lives for the principal classes of assets are as follows:
Buildings and building improvements5 to 39 years
Leasehold improvementsTerm of lease or useful life, whichever is shorter
Furniture, fixtures and equipment3 to 7 years
Vehicles5 years
Computer software3 to 5 years

Software
Capitalized software is stated at cost, less accumulated amortization. Amortization is computed on a straight-line basis and charged to expense over the estimated useful life of the software, which is generally three years. Capitalized software is included in “Premises and equipment, net” in the Consolidated Balance Sheets.
Implementation Costs in a Cloud Computing Arrangement
Implementation costs incurred infor software that is part of a hosting arrangement that is a service contract are capitalized based on criteria in ASC 350-40. The capitalized costs are expensed over the term of the hosting arrangement. Capitalized implementation costs in a cloud computing arrangement are included in “Other assets” in the Consolidated Balance Sheets.Sheets and amortized on a straight-line basis over the life of the contract.
Other Real Estate Owned
OREO is composed of real estate acquired by the Company through either foreclosure or deed in lieu of foreclosure in satisfaction of debt. At acquisition,foreclosure, OREO is recorded at fair value less estimated costs to sell. Any fair value adjustments at acquisitionforeclosure are charged to the allowance, or in the event of a write-up without previous losses charged to the allowance, a credit to earnings is recorded. The fair value of the OREO is based upon a current appraisal or a letter of intent to purchase. Losses that result from the ongoing periodic valuation of these properties are charged to the net cost of operation of OREO in the period in which they are identified. Improvements to OREO are capitalized and holding costs are charged to the net cost of operation of OREO as incurred.
Goodwill and Intangibles
Net assets of companies acquired in a business combination are recorded at fair value at the date of acquisition. Any excess of the purchase price over the fair value of net assets acquired, including identified intangible assets, is recognized as goodwill. Goodwill is reviewed for potential impairment annually, during the third quarter, or, more frequently, if events or circumstances indicate a potential impairment, at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment for which discrete financial information is available and regularly reviewed by management. The Company consists of a single reporting unit. The test for impairment requires the Company to compare the fair value of the reporting unit to its carrying value. If the fair value of the reporting unit includingis less than its carrying value, the difference is the amount of impairment and goodwill is determinedwritten down to be lessthe fair value of the reporting unit. Prior to completing the impairment test, however, the Company may assess qualitative factors to determine whether it is more likely than not that the carrying amountfair value of the reporting unit a furtheris less than its carrying amount. If such an assessment indicates the fair value of the reporting unit is more likely than not greater than its carrying value, then the impairment test is required to measure the amount of impairment. If an impairment loss exists, the carrying amount of goodwill is adjusted to a new cost basis. Subsequent reversal of a previously recognized goodwill impairment loss is prohibited.need not be completed.
Identified intangible assets are amortized on an accelerated basis over the period benefited. Intangible assets are also evaluated for impairment if events and circumstances indicate a possible impairment. Such evaluation is based on undiscounted cash flow projections. At December 31, 2019,2022, intangible assets included in the Consolidated Balance Sheets principally consisted of CDI with an original estimated life of 10 yearsyears.

Leases
The Company determines if a lease is present at the inception of an agreement. Operating leases are capitalized at commencement and are discounted using the Company’s FHLB borrowing rate for a similar term borrowing unless the lease defines an implicita rate within the contract. Leases with original terms of less than 12 months are not capitalized. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease right-of-use assets and operating lease liabilities are recognized on the lease commencement date based on the present value of lease payments over the lease term. The lease term includes options to extend or terminate the lease if the Company is reasonably certain that an option will be exercised. Operating leases are included within “Other assets” in the Consolidated Balance Sheets. See Note 10, “Leases” for additional information on leases.
Income Taxes
The provision for income taxes includes current and deferred income tax expense on net income adjusted for temporary and permanent differences such as interest income from state and municipal securities and investments in affordable housing tax credits. Deferred tax assets and liabilities are recognized for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities using enacted tax laws and rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. On a quarterly basis, management evaluates deferred tax assets to determine if these tax benefits are expected to be realized in future periods. This determination is based on facts and circumstances, including the Company’s current and future tax outlook. To the extent a deferred tax asset is no longer considered “more likely than not” to be realized, a valuation allowance is established.
We recognize the tax benefit from uncertain tax positions only if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to unrecognized tax benefits in “Provision for income taxes” in the Consolidated Statements of Income.
Advertising
Advertising costs are generally expensed as incurred.
Earnings per Common Share
The Company’s capital structure includes common shares, restricted common share awards and common share options, and, during a portion of 2017, convertible preferred shares.options. Restricted common share awards granted prior to the 2018 equity incentive plan participate in dividends declared on common shares at the same rate as common shares. Convertible preferred shares participated in dividends declared on common shares on an “as if converted” basis. RestrictedThese restricted common share awards and convertible preferred shares are considered participating securities under the EPS topic of the FASB ASC.
The Company calculates EPS using the two-class method. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common shareholders but does not require the presentation of basic and diluted EPS for securities other than common shares. Under the two-class method, basic EPS is computed by dividing earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. Earnings allocated to common shareholders represents net income reduced by earnings allocated to participating securities. Diluted EPS is computed in the same manner as basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if certain shares issuable upon exercise of common share options were included unless those additional shares would have been anti-dilutive. For the diluted EPS computation, the treasury stock method is applied and compared to the two-class method and whichever method results in a more dilutive impact is utilized to calculate diluted EPS.
Share-Based Payment
The Company accounts for stock options and stock awards in accordance with the Compensation—Stock Compensation topic of the FASB ASC. Authoritative guidance requires the Company to measure the cost of employee services received in exchange for an award of equity instruments, such as stock options or stock awards, based on the fair value of the award on the grant date. This cost must be recognized in the Consolidated Statements of Income over the vesting period of the award.

66

The Company issues restricted common share awardsRSAs and RSUs which generally vest over a three- or four-year period. RSA and RSU time-based awards vest ratably over their vesting period while RSA and RSU performance-based awards cliff vest. Recipients of RSAs have full voting rights.rights while recipients of RSUs do not. Pursuant to our new equity incentive plan approved in 2018, for any awards issued under the new plan, the holder accrues dividends, which are paid out when the RSAs vest or when the RSUs vest and the common shares vest. For anyare issued. The fair value of time-based and performance-based awards granted priorare equal to the new plan, the holder receives dividends whether or not the shares have vested. Restricted stock is valued at the closing pricefair market value of the Company’s common stock on the grant date. The fair value of market-based performance awards are estimated on the date of an award.grant using the Monte Carlo simulation model.
Derivatives and Hedging Activities
In accordance with the Derivatives and Hedging topic of the FASB ASC, the Company recognizes derivatives as assets or liabilities on the Consolidated Balance Sheets at their fair value. The Company periodically enters into interest rate contracts with customers and offsetting contracts with third parties. As these interest rate contracts are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the changes in fair value of these instruments are recognized immediately in earnings. The Company also enters into forward contracts to sell residential mortgage loans to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential loan commitments. The commitments to originate mortgage loans held for sale and the related forward delivery contracts are considered derivatives.
As part of the Company’s overall interest rate risk management, the Company usesused an interest rate collar with a notional amount of $500.0 million to mitigate interest rate risk. This collar iswas designated and qualifiesqualified as a cash flow hedge. Gains and losses arewere recorded in accumulated other comprehensive income to the extent the hedge iswas effective. Gains and losses arewere reclassified from accumulated other comprehensive income to earnings in the period the hedged transaction affectsaffected earnings and arewas included in the same income statement line item that the hedged transaction was recorded. In October 2020, the interest rate collar was terminated. See Note 17. “Derivatives and Balance Sheet Offsetting” for additional information.
Revenue from Contracts with Customers
Revenue in the scope of Topic 606, Revenue from Contracts with Customersis recorded.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.
a.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.
b.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.
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.
67

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 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 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 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.
Accounting Pronouncements Recently Adopted or Issued
Accounting Standards Adopted in 20192022
In February 2016,December 2022, the FASB issued ASU 2016-02,2022-06, LeasesReference Rate Reform (Topic 842). The amendments included in this ASU create a new accounting model for both lessees and lessors. The new guidance requires lessees to recognize lease liabilities, initially measured at the present value of future lease payments, and corresponding right-of-use assets for all leases with lease terms greater than 12 months. The new lease model differs from the old lease accounting model, as the old model does not require such lease liabilities and corresponding right-of-use assets to be recorded for operating leases. The amendments in ASU 2016-02 must be adopted using the modified retrospective approach and will be effective for the first interim or annual period beginning after December 15, 2018. The FASB subsequently issued ASU 2018-11, which allows for an additional (optional) transition method. The Company adopted the new standard effective January 1, 2019 utilizing the transition method allowed under ASU 2018-11 and did not restate comparative periods. The Company elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classifications and our assessment on whether a contract is or contains a lease. We also elected to keep leases with an initial term of 12 months or less off the balance sheet. The adoption848) - Deferral of the new standard resulted in an increase in other assets and an increase in other liabilitiesSunset Date of $49.2 million and $48.2 million, respectively. The Company recognized a cumulative effect adjustment of $782 thousand to increase the beginning balance of retained earnings related to previous deferred gains on sale-leaseback transactions.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service ContractTopic 848. The amendments in this ASU aligndefer the requirementssunset date included in ASU 2020-04 to provide temporary, optional expedients related to the accounting for capitalizing implementation costs incurred incontract modifications and hedging transactions as a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the termresult of the hosting arrangement, including reasonably certain renewal periods. The amendments inglobal markets’ anticipated transition away from the use of LIBOR and other interbank offered rates to alternative reference rates. Preceding the issuance of ASU 2018-15 are effective for fiscal years beginning2020-04, which established ASC 848, the United Kingdom’s Financial Conduct Authority (“FCA”) announced that it would no longer need to persuade or compel banks to submit to LIBOR after December 15, 201931, 2021. In response, the FASB established a December 31, 2022 expiration date of ASC 848. In March 2021, the FCA announced that the intended cessation date of LIBOR in the United States would be June 30, 2023. Accordingly, ASU 2022-06 defers the expiration date of ASC 848 to December 31, 2024. This ASU was effective immediately and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The amendments can be adopteddid not have a material impact on a prospective or retrospective basis.

The ASU is effective for interim and annual reporting periods beginning after December 15, 2020;2023; early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.Consolidated Financial Statements.

In April 2019,March 2022, the FASB issued ASU 2019-04,2022-02, Codification Improvements to Topic 326, Financial Instruments - Credit Losses Topic 815, Derivatives(Topic 326) - Troubled Debt Restructurings and Hedging, and Topic 825, Financial InstrumentsVintage Disclosures. 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.
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.
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 may 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 certainenhance disclosure requirements for fair value measurements.

Additionally, the changes, entities will no longer be required to discloseamendments require the amountdisclosure of current-period gross charge-offs by year of origination for financing receivables 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.net investments in leases within scope. The ASU is effective for interim and annual reporting periods beginning after December 15, 2019;2022; 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. As the ASU only revised disclosure requirements, adoption of this ASU didis not expected to have a material impact on the Company’s consolidated financial statements.

2.Business Combinations
Pacific ContinentalBank of Commerce
On NovemberOctober 1, 2017,2021, the Company completed its acquisition of Pacific ContinentalBank of Commerce and its wholly-owned banking subsidiary Pacific Continental Bank.Merchants Bank of Commerce. The Company acquired 100% of the equity interests of Pacific Continental. The primary reasons for the acquisition were to expand in the Eugene, Oregon market and improve branch network efficiencies in the Seattle and Portland markets.Bank of Commerce.

The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of the NovemberOctober 1, 20172021 acquisition date. The application of the acquisition method of accounting resulted in the recognition of goodwill of $383.1$57.3 million and a CDI of $46.9$15.9 million. The goodwill represents the excess of the purchase price over the fair value of the net assets acquired. The Company paid this premium for a number of reasons, including to expand the Company’s current footprint, enter the California market and the synergies and economies of scale expected from the acquisition. The goodwill is not deductible for income tax purposes.

For illustrative purposes only, the following table presents certain unaudited pro forma information for the year ended December 31, 2017.2021 and 2020. This unaudited, estimated pro forma financial information was calculated as if Pacific ContinentalBank of Commerce had been acquired as of the beginning of the year prior to the date of acquisition. This unaudited pro forma information combines the historical results of Pacific ContinentalBank of Commerce with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of the beginning of the year prior to the date of acquisition. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value. Additionally, Columbia expects to achievethe pro forma amounts below do not reflect Columbia’s expectations as of the date of the pro forma information of further operating cost savings and other business synergies expected to be achieved, including revenue growth as a result of the acquisition, which are not reflected in the pro forma amounts that follow.acquisition.

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 banks’ Visa Class B conversion ratio to unrestricted Visa Class A shares.
During the year ended December 31, 2020, the Company sold 17,360 shares of Visa Class B restricted stock, which resulted in an observable market price. As a result, the Company adjusted the carrying value of its remaining Visa Class B restricted shares upward to this observable market price. At December 31, 2022, the Company owned 77,683 Visa Class B shares, which had a carrying value of $13.4 million.

The Company’s loans classified as TDR are loans that have been modified or the borrower has been granted special concessions due to financial difficulties, that if not for the challenges of the borrower, the Company would not otherwise consider. The Company had $1.1 million$123 thousand of commitments to lend additional funds on loans classified as TDR as of December 31, 20192022 as compared to $2.1$1.5 million of similar commitments at December 31, 2018.2021. The TDR modifications or concessions are made to increase the likelihood that these borrowers with financial difficulties will be able to satisfy their debt obligations as amended. The concessions granted in the restructurings, summarized in the table above, largely consisted of maturity extensions, interest rate modifications or a combination of both. In limited circumstances, a reduction in the principal balance of the loan could also be made as a concession. Credit losses forconcession. The Company had no loans classified as TDR are measured on the same basis as impaired loans. For impaired loans, an allowance is established when the collateral value less selling costs (or discounted cash flows or observable market price) of the impaired loan is lower than the recorded investment of that loan.The Company did have 1 $26 thousand consumer loan that defaulted within 12 months of being modifiedclassified as a TDR during the year ended December 31, 2019. This defaulted TDR loan did not impact the allowance for loan loss as it paid off prior to year end. The Company did not experience any similar defaults during the years ended December 31, 20182022, 2021 and 2017.2020.
PCI Loans

PCI loans are accounted

6.Allowance for under ASC 310-30Credit Losses and initially measured at fairAllowance for Unfunded Commitments and Letters of Credit
The ACL is determined through quarterly assessments of the present value based onof expected future cash flows overwithin the lifeloan portfolio, which are deducted from the loan’s amortized cost basis to determine the expected credit losses of the loans. Loansloan portfolio. 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 uncollectible 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 commonsegmented 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, risk ratings 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, policy exceptions 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 aggregated into pools.correlated to historical quarterly defaults. The Commercial segment multi-factor models utilize a mix of 15 macroeconomic factors, including the most commonly used factors: Real GDP, National Unemployment Rate, Disposable Personal Income, Home Price Index and Private Inventories. The Consumer segment multi-factor models utilize a mix of three macroeconomic factors: National Unemployment Rate, Home Price Index and Disposable Income. The Company re-measuresutilizes an 18 month reasonable and supportable forecast for the macroeconomic factors, after which the probability of default reverts to its historical mean using a straight-line basis constructed on each macroeconomic factor’s 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 the borrower is experiencing financial difficulty such that full satisfaction of the contractual terms of the loan are in question. 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 collateral dependent loans, 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 atfrom the pool-level,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 a quarterly basis.
Contractual cash flowsunfunded 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 uponon the loan pool terms after applying a prepayment factor. Calculationlikelihood that funding will occur and an estimate of what will be funded by analyzing the applied prepayment factormost recent four-quarter utilization rates, current utilization and our quantitative ACL rate. The allowance for contractual cash flowsunfunded commitments and letters of credit is included in “Other Liabilities” on the same as described below for expected cash flows.
InputsConsolidated Balance Sheets, with changes to the determination of expected cash flows include cumulative default and prepayment databalance 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 well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a particular delinquency state (e.g. 0-30 days past due, 31reduction to 60 days, etc.) given its delinquency state at the re-measurement date. Loss severity factors are based upon either actual charge-off data within the loan pools or industry averages, and recovery lags are based upon the collateral within the loan pools.
The excess of cash flows expected to be collected over the initial fair value of PCI loans is referred to as the accretable yield and is accreted into interest income over the estimated lifewhen loans are placed on nonaccrual status.

The $2.9 million increase in the ACL at December 31, 2022 compared to the ACL at December 31, 2021 was primarily due to the increase in the size of the loan portfolio. This was partially offset by significant improvement in the portfolio composition with declining special mention and substandard loans as a percentage of the portfolio, lower anticipated losses given default and the reductions of pandemic-related model inputs. The ACL does not include a reserve for the PPP loans as these loans are fully guaranteed by the SBA.

Risk ElementsCredit Quality Indicators
The extension of credit in the form of loans or other credit products to individualsconsumer and businessescommercial 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. In the event full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrantsAll loans risk rated special mention or worse with amortized costs exceeding $250,000 are reviewed at least quarterly with more frequent review for specific reserves or a write-down of the loan.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 uncollectableuncollectible and when identified, are charged-off.

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 and between annual tests in certain circumstances such as upon 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 its annual impairment assessment as of July 31, 20192022 and concluded that there was no impairment. As of December 31, 2019,2022, we determined there were no events or circumstances which would more likely than not reduce the fair value of our reporting unit below its carrying amount.
The CDI isOur CDIs are evaluated for impairment if events and circumstances indicate a possible impairment. The CDI isCDIs are amortized on an accelerated basis over an estimated life of 10 years.years each.

16.Derivatives and Balance Sheet Offsetting
17.Derivatives 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 andas well as 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,.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 usesused an interest rate collarscollar 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 arewere 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 beare 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 $3.2$10.4 million reclassified as an increase to interest income.

The Company may use derivatives to hedge the risk or changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. These derivatives are not designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes interest rate forward loan sales contracts in its derivative risk management strategy.
88

The Company enters into forward delivery contracts to sell residential mortgage loans to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments. Credit risk associated with forward contracts is limited to the replacement cost of those forward contracts in a gain position. There were no counterparty default losses on forward contracts during the years ended December 31, 2022, 2021 and 2020. Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward contracts with broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker/dealer equal to the increase or decrease in the market value of the forward contract. At December 31, 2022 the Bank had no commitments to originate mortgage loans held for sale under the mandatory delivery method and had $21.8 million of loans held for sale under the mandatory delivery method at December 31, 2021. The Bank had no forward sales commitments at December 31, 2022 and had $18.5 million at December 31, 2021, which are used to hedge both on-balance sheet and off-balance sheet exposures.
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 loan. 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 December 31, 20192022 and 20182021 was $428.6$520.9 million and $366.7$570.2 million, respectively. Mark-to-market loss of $1 thousand for 2019 and mark-to-market gains of $8 thousand and $16 thousand for 2018 and 2017, respectively, were recorded to “Other” noninterest expense.

Fair Value Accounting and Measurement
21.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:
SecuritiesDebt securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury Notesdebt securities.
Loans held for sale include the fair value of residential mortgage loans originated as held for sale determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights. The change in fair value of loans held for sale is primarily driven by changes in interest rates subsequent to loan funding and other securities, whichchanges in the fair value of the related servicing asset, resulting in revaluation adjustments to the recorded fair value.
94

The fair value of the interest rate lock commitments and interest rate forward loan sales contracts are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate. The pull-through rate assumptions are considered a Level 1 input method.3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3.
Interest rate swap 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.

95

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at December 31, 20192022 and 20182021 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

Nonrecurring Measurements
Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment and OREO.collateral dependent loans. The following methodsvaluation techniques and inputs were used to estimate the fair value of each such class of financial instrument:collateral dependent loans.
ImpairedCollateral dependent loans- A collateral dependent loan is considereda loan in which repayment is expected to be impaired when, based on current information and events, it is probable thatprovided solely by the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or theunderlying 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 estimated costs to sell if thesell. The collateral dependent loan is a collateral-dependent loan. The impairment evaluationsvaluations are performed in conjunction with the ALLLallowance for credit losses process on a quarterly basisbasis.
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 officersan 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 Special Credits group, which reportsevent of a write-up without previous losses charged to the Chief Credit Officer. The REASD, which also reportsallowance for credit losses, a credit to earnings is recorded. Management periodically reviews OREO in an effort to ensure the Chief Credit Officer,property is responsible for obtaining appraisals from third-partiesrecorded at its fair value, net of estimated costs to sell. Any fair value adjustments subsequent to acquisition are charged or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisalcredited to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.earnings.

At December 31, 2022 the Company did not have any loans held for sale sold under the mandatory delivery method accounted for under the fair value option while at December 31, 2021 the Company had this type of loans held for sale with a fair value of $9.6 million and an aggregate unpaid principle balance of $9.4 million, resulting in an aggregate difference of $169 thousand.
22.Earnings Per Common Share
Residential mortgage loans held for sale that are sold under the mandatory delivery method and accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported in loan revenue. For the years ended December 31, 2022 and 2021, the Company recorded net decreases in fair value of $169 thousand and $339 thousand, respectively, representing the change in fair value reflected in earnings. For the year ended December 31, 2020, the Company recorded a net increase of $508 thousand, representing the change in fair value reflected in earnings.
23.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 issueshas issued restricted shares under share-based compensation plans and preferred shares which qualify as participating securities.

Share-Based Payments
23.Share-Based Payments
At December 31, 2019,2022, the Company had one equity compensation plan (the “Plan”), which is shareholder approved, that provides for the granting of share options, share units and shares to eligible employees and directors up to 3,050,000 shares.
Share Units: Restricted share units provide for an interest in Company common stock to the recipient, with such units held in escrow until certain conditions are met. Share units provide for vesting requirements that include time-based, performance-based, or market-based conditions. Recipients of restricted units do not pay any cash consideration to the Company for the units and the holders of the restricted units do not have voting rights. For share units issued under the equity incentive plan approved in 2018, the holder accrues dividends, which are paid out when the units vest and the shares are issued. The fair value of time-based and performance-based units is equal to the fair market value of the Company’s common stock on the grant date. The fair value of market-based units is estimated on the grant date using the Monte Carlo simulation model.

As of December 31, 2019,2022, there was $23.1$14.5 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted average period of 2.71.7 years. The total fair value, as measured on the date of vesting, of shares vested during the years ended December 31, 2019, 2018,2022, 2021, and 20172020 was $8.7$13.8 million, $6.7$12.6 million, and $6.5$8.1 million, respectively.
Share Options: Option awards are generally granted with an exercise price equal to the market price of the Company’s stock at the date of grant; those option awards generally vest based on three years of continual service and are exercisable for a five-year period after vesting. Option awards granted have a 10-year maximum term.
The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model. The fair value of all options is amortized on a straight-line basis over the requisite service periods, which are generally the vesting periods. The expected life of options granted represents the period of time that they are expected to be outstanding. The expected life is determined based on historical experience with similar awards, giving consideration to the contractual terms and vesting schedules. Expected volatilities of our common stock are estimated at the date of grant based on the historical volatility of the stock. The volatility factor is based on historical stock prices over the most recent period commensurate with the estimated expected life of the award. The risk-free interest rate is based on the U.S. Treasury curve in effect at the time of the award. The expected dividend yield is based on dividend trends and the market value of the Company’s stock price at the time of the award.

As of December 31, 20192022 and 2018,2021, we had 0no unrecognized tax benefits. Our policy is to recognize interest and penalties on unrecognized tax benefits in “Provision for income taxes” in the Consolidated Statements of Income. There were 0no amounts related to interest and penalties recognized for the years ended December 31, 20192022 and 2018.2021. As a result of recent acquisitions, the Company has net operating loss carryforwards in the federal, Idaho and Oregon jurisdictions of $15.8$9.9 million, $14.3$5.4 million and $121$25 thousand, respectively, which begin to expire in 2024.

The Company invests in limited partnerships that operate qualified affordable housing projects to receive tax benefits in the form of tax deductions from operating losses and tax credits. The Company accounts for the investments using the proportional amortization method; amortization of the investment in qualified affordable housing projects is recorded in the provision for income taxes together with tax credits and benefits received. As of December 31, 2022, 2021 and 2020, the Company recognized $1.8 million, $916 thousand, and $622 thousand, respectively, of proportional amortization as a component of income tax expense and recognized $2.0 million, $1.2 million, and $738 thousand, respectively, in affordable housing tax credits and other tax benefits during the years. The Company’s low-income housing tax credit investments at December 31, 2022 and 2021 were approximately $47.2 million and $24.0 million, respectively, and are included in “Other Assets” on the Consolidated Balance Sheets. The Company’s remaining capital commitments to these partnerships at December 31, 2022 and 2021 were approximately $41.3 million and $19.2 million, respectively, and are included in “Other Liabilities” on the Consolidated Balance Sheets.
On March 27, 2020, the CARES Act was enacted in response to the COVID-19 pandemic. The Tax CutsCARES Act, among other things, permits NOL carryovers and Jobscarrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company has evaluated the impact of the CARES Act and determined that none of the changes would result in a material income tax benefit to the Company.
On December 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law on December 22, 2017.and extends several provisions of the CARES Act.

25.Regulatory Capital Requirements
26.Regulatory Capital Requirements
The Company (on a consolidated basis) and its banking subsidiary are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and its banking subsidiary’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its banking subsidiary must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.
Basel III capital requirements became effective on January 1, 2015.
103

The capital requirements, among other things (i) specify that Tier 1 capital consists of CET1, and “Additional Tier 1 capital” instruments meeting specified requirements, (ii) define CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital and (iii) expand the scope of the deductions/adjustments to capital as compared to existing regulations. Under the requirements that are now effective, the minimum capital ratios are (i) 4.5% CET1 to risk-weighted assets, (ii) 6% Tier 1 capital to risk-weighted assets, (iii) 8% total capital to risk-weighted assets and (iv) 4% Tier 1 capital to average total assets (Tier 1 leverage). The Company and the Bank have made the one-time election to opt-out of including accumulated other comprehensive income items in regulatory capital calculations.
The Capital Rules also require a capital conservation buffer designed to absorb losses during periods of economic stress. The capital conservation buffer is composed entirely of CET1, on top of these minimum risk-weighted asset ratios. In addition, the Capital Rules provide for a countercyclical capital buffer applicable only to certain covered institutions. We do not expect the countercyclical capital buffer to be applicable to us or the Bank. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall.
The implementation of the capital conservation buffer began on January 1, 2016is set at the 0.625% level and was fully phased in over a three-year period (increasing by 0.625% on each subsequent January 1, until it reached 2.5% on January 1, 2019). As a result, the Company and the Bank are now required to maintain such additional capital conservation buffer of 2.5% of CET1, effectively resulting in minimum ratios of (i) 7% CET1 to risk-weighted assets, (ii) 8.5% Tier 1 capital to risk-weighted assets, and (iii) 10.5% total capital to risk-weighted assets. At December 31, 2019,2022, the capital conservation buffer for the Company and the Bank was 5.60%5.98% and 5.29%5.97%, respectively. As of December 31, 2019,2022, 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. To qualify as “well-capitalized,” banks must have a CET1 risk-adjusted capital ratio of 6.5%, a Tier I risk-adjusted capital ratio of at least 8%, a total risk-adjusted capital ratio of at least 10% and a leverage ratio of at least 5%. Failure to qualify as “well-capitalized” can negatively impact a bank’s ability to expand and to engage in certain activities.
As of December 31, 2019,2022, the most recent notification from the FDIC categorized Columbia Bank as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well- capitalized, an institution must maintain minimum CET1 risk-based, Tier 1 risk-based, total risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since the notification that management believes have changed Columbia Bank’s category.

28.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.
a.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.
b.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.
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.

On January 9, 2023, we announced that Columbia, Umpqua, and Cascade Merger Sub, Inc. (“Merger Sub”) entered into Amendment No. 1 (the “Amendment) to the Agreement and Plan of Merger, dated as of October 11, 2021 (as amended, the “Merger Agreement”) extending the Termination Date (as defined in the Merger Agreement) to March 11, 2023.

Total deposits and loans that were divested upon closing were $116.1 million and $3.8 million, respectively. Columbia recorded a gain of $3.7 million related to the completion of this divestiture.
Columbia is required to complete an additional divestiture of 7 branches and certain related assets and deposit liabilities in certain of its Washington and Oregon markets to satisfy regulatory requirements in connection with its merger with Umpqua. The Company has an agreement to sell these branches to 1st Security Bank of Washington, a wholly-owned subsidiary of FS Bancorp, Inc.

ITEM 9A.    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 Security Exchange Commission’s rules and forms.
Internal Control Over Financial Reporting
Management’s Annual Report On Internal Control Over Financial Reporting
The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting. The internal control system has been designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation and fair presentation of the Company’s published financial statements. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect the Company’s transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of the Company’s financial statements; providing reasonable assurance that receipts and expenditures are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on the Company’s financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of the Company’s financial statements would be prevented or detected.
The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019.2022. In making this assessment, it used the criteria set forth by the COSO in Internal Control-Integrated Framework (2013).
Based on such evaluation, management has concluded that the Company’s internal control over financial reporting is effective as of December 31, 2019.2022. There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during our most recently completed fiscal quarter that materially affected or are reasonably likely to materially affect internal control over financial reporting.
Our independent registered public accounting firm has issued an attestation report on our internal control over financial reporting, which appears in this annual report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholdersShareholders and the Board of Directors of Columbia Banking System, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Columbia Banking System, Inc. and its subsidiaries (the “Company”) as of December 31, 2019,2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Because management's assessment and our audit were conducted to meet the reporting requirements of Section 112 of the Federal Deposit Insurance Corporation Improvement Act (FDICIA), management's assessment and our audit of the Company's internal control over financial reporting included controls over the preparation of the schedules equivalent to the basic financial statements in accordance with the instructions for the Federal Financial Institutions Examination Council Instructions for Consolidated Reports of Condition and Income for Schedules RC, RI, and RI-A. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We have not examined and, accordingly, we do not express an opinion or any other form of assurance on management's statement referring to compliance with laws and regulations.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2019,2022, of the Company and our report dated February 27, 2020,24, 2023, expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
