Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Basis of Presentation Bank of Hawaii Corporation (the “Parent”) is a Delaware corporation and a bank holding company headquartered in Honolulu, Hawaii. Bank of Hawai‘i Corporation is a trade name of Bank of Hawaii Corporation, and along with its subsidiaries (collectively, the “Company”) provide a broad range of financial products and services to businesses, consumers and governments in Hawaii and the West Pacific. The majority of the Company’s operations consist of customary commercial and consumer banking services including, but not limited to, lending, leasing, deposit services, trust and investment activities, brokerage services, and trade financing. The accompanying consolidated financial statements include the accounts of the Parent and its subsidiaries. The Parent’s principal operating subsidiary is Bank of Hawaii (the “Bank”), doing business as Bank of Hawai‘i. The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period information has been reclassified to conform to the current period presentation. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full fiscal year or for any future period. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and accompanying notes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 . Accounting Standard Pending Adoption In March 2023, the FASB issued ASU 2023-02, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. ASU 2023-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. ASU 2023-02 is not expected to have a material impact on the Company’s consolidated financial statements.

As of March 31, 2023, and December 31, 2022, the gross unrealized loss positions were primarily related to mortgage-backed securities 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. Total gross unrealized losses were attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell the investment securities that were in an unrealized loss position and it is not more likely than not that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity. Substantially all of the Company’s HTM debt securities are 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, an allowance for credit losses for these securities was not deemed necessary as of March 31, 2023. Interest income from taxable and non-taxable investment securities for the three months ended March 31, 2023, and March 31, 2022, were as follows: Three Months Ended (dollars in thousands) 2023 2022 Taxable $ 47,757 $ 35,790 Non-Taxable 84 11 Total Interest Income from Investment Securities $ 47,841 $ 35,801 As of March 31, 2023, and December 31, 2022, the carrying value of the Company’s Federal Home Loan Bank of Des Moines stock and Federal Reserve Bank stock was as follows: (dollars in thousands) March 31, December 31, Federal Home Loan Bank of Des Moines Stock $ 43,000 $ 26,000 Federal Reserve Bank Stock 27,182 27,065 Total $ 70,182 $ 53,065 These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution. The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value.

A substantial portion of the Company’s real estate loans are secured by real estate in Hawaii. Net gains related to sales of residential mortgage loans, recorded as a component of mortgage banking income was less than $ 0.1 million for the three months ended March 31, 2023 and March 31, 2022.

Allowance for Credit Losses (the “Allowance”) The following presents by portfolio segment, the activity in the Allowance for the three months ended March 31, 2023, and March 31, 2022.

The Company uses an internal credit risk rating system that categorizes loans and leases into pass, special mention, or classified categories. Credit risk ratings are applied individually to those classes of loans and leases that have significant or unique credit characteristics that benefit from a case-by-case evaluation. These are typically loans and leases to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans and leases that are underwritten and structured using standardized criteria and characteristics are typically monitored and risk-rated collectively. These are typically loans and leases to individuals in the classes which comprise the consumer portfolio segment. The following are the definitions of the Company’s credit quality indicators: Pass: Loans and leases in all classes within the commercial and consumer portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan or lease agreement. Residential mortgage loans that are past due 90 days or more as to principal or interest may be considered Pass if the current loan-to-value ratio is 60 % or less. Home equity loans that are past due 90 days or more as to principal or interest may be considered Pass if: a) the home equity loan is in a first lien position and the current loan-to-value ratio is 60 % or less; or b) the first mortgage is with the Company and the current combined loan-to-value ratio is 60 % or less. Special Mention: Loans and leases in all classes within the commercial portfolio segment that have potential weaknesses that deserve management’s close attention. If not addressed, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease. The Special Mention credit quality indicator is not used for the consumer portfolio segment. Classified: Loans and leases in the classes within the commercial portfolio segment that are inadequately protected by the sound worth and paying capacity of the borrower or of the collateral pledged, if any. Classified loans and leases are also those in the classes within the consumer portfolio segment that are past due 90 days or more as to principal or interest. Residential mortgage and home equity loans may be current as to principal and interest, but may be considered Classified for a period of generally up to six months following a loan modification. Following a period of demonstrated performance in accordance with the modified contractual terms, the loan may be removed from Classified status. For Pass rated credits, risk ratings are certified at a minimum annually. For Special Mention or Classified credits, risk ratings are reviewed for appropriateness on an ongoing basis, monthly, or at a minimum, quarterly. The following presents by credit quality indicator, loan class, and year of origination, the amortized cost basis of the Company’s loans and leases as of March 31, 2023.

The Company does not recognize interest income while loans or leases are on non-accrual status. Loan Modifications to Borrowers Experiencing Financial Difficulty In January 2023 , the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), which eliminated the accounting guidance for troubled debt restructurings (“TDRs”) while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Upon adoption of this guidance, the Company no longer establishes a specific reserve for modifications to borrowers experiencing financial difficulty. Instead, these modifications are included in their respective cohort and a historical loss rate is applied to the current loan balance to arrive at the quantitative baseline portion of the Allowance. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearances, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. The following illustrates the most common loan modifications by loan classes offered by the Company that are required to be disclosed pursuant to the requirements of ASU 2022-02: Loan Classes Modification Types Commercial: Term extension, interest rate reductions, payment delay, or combination thereof. These modifications extend the term of the loan, lower the payment amount, or otherwise delay payments during a defined period for the purpose of providing borrowers additional time to return to compliance with the original loan term. Residential Mortgage/ Forbearance period greater than six months. These modifications require reduced or no payments during the forbearance period for the purpose of providing borrowers additional time to return to compliance with the original loan term. Residential Mortgage/ Term extension and rate adjustment. These modifications extend the term of the loan and provides for an adjustment to the interest rate, which reduces the monthly payment requirement. Automobile/ Term extension greater than three months. These modifications extend the term of the loan, which reduces the monthly payment requirement.

Mortgage Servicing Rights

Mortgage Servicing Rights	3 Months Ended
	Mar. 31, 2023
Transfers And Servicing Of Financial Assets [Abstract]
Mortgage Servicing Rights	Note 5. Mortgage Servicing Rights The Company’s portfolio of residential mortgage loans serviced for third parties was $ 2.6 billion as of March 31, 2023, and $ 2.6 billion as of December 31, 2022. Substantially all of these loans were originated by the Company and sold to third parties on a non-recourse basis with servicing rights retained. These retained servicing rights are recorded as a servicing asset and are initially recorded at fair value (see Note 13 Fair Value of Assets and Liabilities for more information). Changes to the balance of mortgage servicing rights are recorded in mortgage banking income in the Company’s consolidated statements of income. The Company’s mortgage servicing activities include collecting principal, interest, and escrow payments from borrowers; making tax and insurance payments on behalf of borrowers; monitoring delinquencies and executing foreclosure proceedings; and accounting for and remitting principal and interest payments to investors. Servicing income, including late and ancillary fees, was $ 1.4 million and $ 1.5 million for the three months ended March 31, 2023, and March 31, 2022, respectively. Servicing income is recorded in mortgage banking income in the Company’s consolidated statements of income. The Company’s residential mortgage investor loan servicing portfolio is primarily comprised of fixed rate loans concentrated in Hawaii. For the three months ended March 31, 2023, and March 31, 2022, the change in the carrying value of the Company’s mortgage servicing rights accounted for under the fair value measurement method was as follows: Three Months Ended (dollars in thousands) 2023 2022 Balance at Beginning of Period $ 717 $ 800 Change in Fair Value Due to Payoffs ( 10 ) ( 19 ) Balance at End of Period $ 707 $ 781 For the three months ended March 31, 2023, and March 31, 2022, the change in the carrying value of the Company’s mortgage servicing rights accounted for under the amortization method was as follows: Three Months Ended (dollars in thousands) 2023 2022 Balance at Beginning of Period $ 21,902 $ 21,451 Servicing Rights that Resulted From Asset Transfers 65 751 Amortization ( 572 ) ( 844 ) Valuation Allowance Recovery (Provision) — 1,829 Balance at End of Period $ 21,395 $ 23,187 Valuation Allowance: Balance at Beginning of Period $ — $ ( 1,829 ) Valuation Allowance Recovery (Provision) — 1,829 Balance at End of Period $ — $ — Fair Value of Mortgage Servicing Rights Accounted for Beginning of Period $ 27,323 $ 21,451 End of Period $ 26,456 $ 26,088 The key data and assumptions used in estimating the fair value of the Company’s mortgage servicing rights as of March 31, 2023, and December 31, 2022, were as follows: March 31, December 31, Weighted-Average Constant Prepayment Rate 1 4.35 % 4.02 % Weighted-Average Life (in years) 9.36 9.64 Weighted-Average Note Rate 3.61 % 3.60 % Weighted-Average Discount Rate 2 9.84 % 9.93 % 1. Represents annualized loan prepayment rate assumption. 2. Derived from multiple interest rate scenarios that incorporate a spread to a market yield curve and market volatilities. A sensitivity analysis of the Company’s fair value of mortgage servicing rights to changes in certain key assumptions as of March 31, 2023, and December 31, 2022, is presented in the following table. (dollars in thousands) March 31, December 31, Constant Prepayment Rate Decrease in fair value from 25 basis points (“bps”) adverse change $ ( 334 ) $ ( 346 ) Decrease in fair value from 50 bps adverse change ( 662 ) ( 686 ) Discount Rate Decrease in fair value from 25 bps adverse change ( 304 ) ( 316 ) Decrease in fair value from 50 bps adverse change ( 602 ) ( 626 ) This analysis generally cannot be extrapolated because the relationship of a change in one key assumption to the change in the fair value of the Company’s mortgage servicing rights usually is not linear. Also, the effect of changing one key assumption without changing other assumptions is not realistic.

Affordable Housing Projects Tax

Affordable Housing Projects Tax Credit Partnerships	3 Months Ended

Equity Method Investments And Joint Ventures [Abstract]
Affordable Housing Projects Tax Credit Partnerships	Note 6. Affordable Housing Projects Tax Credit Partnerships The Company makes equity investments in various limited partnerships or limited liability companies that sponsor affordable housing projects utilizing the Low Income Housing Tax Credit (“LIHTC”) pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to achieve a satisfactory return on capital, to facilitate the sale of affordable housing product offerings, and to assist in achieving goals associated with the Community Reinvestment Act. The primary activities of these entities include the identification, development, and operation of multi-family housing that is leased to qualifying residential tenants. Generally, these types of investments are funded through a combination of debt and equity. The Company is a limited partner or non-managing member in each LIHTC limited partnership or limited liability company, respectively. Each of these entities is managed by an unrelated third-party general partner or managing member who exercises significant control over the affairs of the entity. The general partner or managing member has all the rights, powers and authority granted or permitted to be granted to a general partner of a limited partnership or managing member of a limited liability company. Duties entrusted to the general partner or managing member include, but are not limited to: investment in operating companies, company expenditures, investment of excess funds, borrowing funds, employment of agents, disposition of fund property, prepayment and refinancing of liabilities, votes and consents, contract authority, disbursement of funds, accounting methods, tax elections, bank accounts, insurance, litigation, cash reserve, and use of working capital reserve funds. Except for limited rights granted to the limited partner(s) or non-managing member(s) relating to the approval of certain transactions, the limited partner(s) and non-managing member(s) may not participate in the operation, management, or control of the entity’s business, transact any business in the entity’s name or have any power to sign documents for or otherwise bind the entity. In addition, the general partner or managing member may only be removed by the limited partner(s) or managing member(s) in the event of a failure to comply with the terms of the agreement or negligence in performing its duties. The general partner or managing member of each entity has both the power to direct the activities which most significantly affect the performance of each entity and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. Therefore, the Company has determined that it is not the primary beneficiary of any LIHTC entity. The Company uses the effective yield method to account for its pre-2015 investments in these entities. Beginning January 1, 2015, any new investments that meet the requirements of the proportional amortization method are recognized using the proportional amortization method. The Company’s net affordable housing tax credit investments including the related unfunded commitments were $ 189.3 million and $ 174.5 million as of March 31, 2023, and December 31, 2022, respectively, and are included in other assets in the consolidated statements of condition. Unfunded Commitments As of March 31, 2023, the expected payments for unfunded affordable housing commitments were as follows: (dollars in thousands) Amount 2023 $ 47,729 2024 24,731 2025 24,115 2026 156 2027 133 Thereafter 509 Total Unfunded Commitments $ 97,373 The following table presents tax credits and other tax benefits recognized and amortization expense related to affordable housing for the three months ended March 31, 2023, and March 31, 2022.

Segment Reporting [Abstract]
Business Segments	Note 10. Business Segments The Company’s business segments are defined as Consumer Banking, Commercial Banking, and Treasury and Other. The Company’s internal management accounting process measures the performance of these business segments. This process, which is not necessarily comparable with the process used by any other financial institution, uses various techniques to assign balance sheet and income statement amounts to the business segments, including allocations of income, expense, the provision for credit losses, and capital. This process is dynamic and requires certain allocations based on judgment and other subjective factors. Unlike financial accounting, there is no comprehensive authoritative guidance for management accounting that is equivalent to GAAP. Previously reported results have been reclassified to conform to the current reporting structure. The net interest income of the business segments reflects the results of a funds transfer pricing process that matches assets and liabilities with similar interest rate sensitivity and maturity characteristics and reflects the allocation of net interest income related to the Company’s overall asset and liability management activities on a proportionate basis. The basis for the allocation of net interest income is a function of the Company’s assumptions that are subject to change based on changes in current interest rates and market conditions. Funds transfer pricing also serves to transfer interest rate risk to Treasury. However, the other business segments have some latitude to retain certain interest rate exposures related to customer pricing decisions within guidelines. The provision for credit losses for the Consumer Banking and Commercial Banking business segments reflects the actual net charge-offs of those business segments. The amount of the consolidated provision for loan and lease losses is based on the methodology that the Company used to estimate our consolidated Allowance. The residual provision for credit losses to arrive at the consolidated provision for credit losses is included in Treasury and Other. Noninterest income and expense includes allocations from support units to business units. These allocations are based on actual usage where practicably calculated or by management’s estimate of such usage. The provision for income taxes is allocated to business segments using a 26 % effective income tax rate. However, the provision for income taxes for our Commercial Leasing portfolio (included in the Commercial Banking segment) and Auto Leasing portfolio and Pacific Century Life Insurance business unit (both included in the Consumer Banking segment) are assigned their actual effective income tax rates due to the unique relationship that income taxes have with their products. The residual income tax expense or benefit to arrive at the consolidated effective tax rate is included in Treasury and Other. Consumer Banking Consumer Banking offers a broad range of financial products and services, including loan, deposit and insurance products; private banking and international client banking services; trust services; investment management; and institutional investment advisory services. Consumer Banking also provides a full service brokerage offering equities, mutual funds, life insurance, and annuity products. Loan and lease products include residential mortgage loans, home equity lines of credit, automobile loans and leases, personal lines of credit, installment loans, small business loans and leases, and credit cards. Deposit products include checking, savings, and time deposit accounts. Private banking and personal trust groups assist individuals and families in building and preserving their wealth by providing investment, credit, and trust services to high-net-worth individuals. The investment management group manages portfolios utilizing a variety of investment products. Also within Consumer Banking, institutional client services offer investment advice to corporations, government entities, and foundations. Products and services from Consumer Banking are delivered to customers through 51 branch locations and 320 ATMs throughout Hawaii and the Pacific Islands, e-Bankoh (online banking service), a customer service center, and a mobile banking service. Commercial Banking Commercial Banking offers products including corporate banking, commercial real estate loans, commercial lease financing, auto dealer financing, and deposit products. Commercial lending and deposit products are offered to middle-market and large companies in Hawaii and the Pacific Islands. In addition, Commercial Banking offers deposit products to government entities in Hawaii. Commercial real estate mortgages focus on customers that include investors, developers, and builders predominantly domiciled in Hawaii. Commercial Banking also includes international banking and provides merchant services to its customers. Treasury and Other Treasury consists of corporate asset and liability management activities, including interest rate risk management and a foreign currency exchange business. This segment’s assets and liabilities (and related interest income and expense) consist of interest-bearing deposits, investment securities, federal funds sold and purchased, and short and long-term borrowings. The primary sources of noninterest income are from bank-owned life insurance, net gains from the sale of investment securities, and foreign exchange income related to customer-driven currency requests from merchants and island visitors. The net residual effect of the transfer pricing of assets and liabilities is included in Treasury, along with the elimination of intercompany transactions. Other organizational units (Technology, Operations, Marketing, Human Resources, Finance, Credit and Risk Management, and Corporate and Regulatory Administration) provide a wide-range of support to the Company’s other income earning segments. Expenses incurred by these support units are charged to the business segments through an internal cost allocation process.

As of March 31, 2023, and December 31, 2022, the Company did not designate any derivative financial instruments as formal hedging relationships. Interest Rate Swap Agreements The Company enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting interest rate swap agreements with highly rated third party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated statements of condition (asset positions are included in other assets and liability positions are included in other liabilities). The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of marketable securities, is posted by the party (i.e., the Company or the financial institution counterparty) with net liability positions in accordance with contract thresholds. The fair values of certain counterparty interest rate swaps are zero due to the settlement of centrally-cleared variation margin rules. The Company had net asset positions with its financial institution counterparties totaling $ 65.5 million and $ 38.8 million as of March 31, 2023, and December 31, 2022, respectively. Conversion Rate Swap Agreements As certain sales of Visa Class B restricted shares were completed, the Company entered into a conversion rate swap agreement with the buyer that requires payment to the buyer in the event Visa further reduces the conversion ratio of Class B into Class A unrestricted common shares. In the event of Visa increasing the conversion ratio, the buyer would be required to make payment to the Company. As of March 31, 2023, and December 31, 2022 , the conversion rate swap agreement was valued at zero (i.e., no contingent liability recorded) as further reductions to the conversion ratio were deemed neither probable nor reasonably estimable by management.

Commitments and Contingencies	Note 12. Commitments and Contingencies The Company’s credit commitments as of March 31, 2023, and December 31, 2022, were as follows: (dollars in thousands) March 31, December 31, Unfunded Commitments to Extend Credit $ 3,582,980 $ 3,592,872 Standby Letters of Credit 133,397 129,512 Commercial Letters of Credit 15,804 24,030 Total Credit Commitments $ 3,732,181 $ 3,746,414 Unfunded Commitments to Extend Credit Commitments to extend credit are agreements to lend to a customer as long as there is no violation of the terms or conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since commitments may expire without being drawn, the total commitment amount does not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. Standby letters of credit generally become payable upon the failure of the customer to perform according to the terms of the underlying contract with the third-party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and a third party. The contractual amount of these letters of credit represents the maximum potential future payments guaranteed by the Company. The Company has recourse against the customer for any amount it is required to pay to a third-party under a standby letter of credit, and generally holds cash or deposits as collateral on those standby letters of credit for which collateral is deemed necessary. Assets valued at $ 108.2 million secured certain specifically identified standby letters of credit as of March 31, 2023. As of March 31, 2023, the standby and commercial letters of credit had remaining terms ranging from 1 to 14 months . Contingencies The Company is subject to various pending and threatened legal proceedings arising out of the normal course of business or operations. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal proceedings using the most recent information available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. Based on information currently available, management believes that the eventual outcome of any claims against the Company will not be materially in excess of such amounts reserved by the Company. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters may result in a loss that materially exceeds the reserves established by the Company.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Note 13. Fair Value of Assets and Liabilities Fair Value Hierarchy Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP established a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels: Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and is used to measure fair value whenever available. A contractually binding sales price also provides reliable evidence of fair value. Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that utilize model-based techniques for which all significant assumptions are observable in the market. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement; inputs to the valuation methodology that utilize model-based techniques for which significant assumptions are not observable in the market; or inputs to the valuation methodology that require significant management judgment or estimation, some of which may be internally developed. In some instances, an instrument may fall into multiple levels of the fair value hierarchy. In such instances, the instrument’s level within the fair value hierarchy is based on the lowest of the three levels (with Level 3 being the lowest) that is significant to the fair value measurement. Our assessment of the significance of an input requires judgment and considers factors specific to the instrument. Assets and Liabilities Measured at Fair Value on a Recurring Basis Investment Securities Available-for-Sale Level 1 investment securities are comprised of debt securities issued by the U.S. Treasury, as quoted prices were available, unadjusted, for identical securities in active markets. Level 2 investment securities were primarily comprised of debt securities issued by the Small Business Administration, states and municipalities, corporations, as well as mortgage-backed securities issued by government agencies and government-sponsored enterprises. Fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models. In cases where there may be limited or less transparent information provided by the Company’s third party pricing service, fair value may be estimated by the use of secondary pricing services or through the use of non-binding third party broker quotes. Loans Held for Sale The fair value of the Company’s residential mortgage loans held for sale was determined based on quoted prices for similar loans in active markets, and therefore, is classified as a Level 2 measurement. Mortgage Servicing Rights The Company estimates the fair value of mortgage servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The Company stratifies its mortgage servicing portfolio on the basis of loan type. The assumptions used in the discounted cash flow model are those that the Company believes market participants would use in estimating future net servicing income. Significant assumptions in the valuation of mortgage servicing rights include estimated loan repayment rates, the discount rate, servicing costs, and the timing of cash flows, among other factors. Mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other Assets Other assets recorded at fair value on a recurring basis are primarily comprised of investments related to deferred compensation arrangements. Quoted prices for these investments, primarily in mutual funds, are available in active markets. Thus, the Company’s investments related to deferred compensation arrangements are classified as Level 1 measurements in the fair value hierarchy. Derivative Financial Instruments Derivative financial instruments recorded at fair value on a recurring basis are comprised of interest rate lock commitments (“IRLCs”), forward commitments, interest rate swap agreements, foreign exchange contracts, and Visa Class B to Class A shares conversion rate swap agreements. The fair values of IRLCs are calculated based on the value of the underlying loan held for sale, which in turn is based on quoted prices for similar loans in the secondary market. However, this value is adjusted by a factor which considers the likelihood that the loan in a locked position will ultimately close. This factor, the closing ratio, is derived from the Bank’s internal data and is adjusted using significant management judgment. As such, IRLCs are classified as Level 3 measurements. Forward commitments are classified as Level 2 measurements as they are primarily based on quoted prices from the secondary market based on the settlement date of the contracts, interpolated or extrapolated, if necessary, to estimate a fair value as of the end of the reporting period. The fair values of interest rate swap agreements are calculated using a discounted cash flow approach and utilize Level 2 observable inputs such as a market yield curve, effective date, maturity date, notional amount, and stated interest rate. The valuation methodology for interest rate swaps with financial institution counterparties (and the related customer interest rate swaps) is based on the Secured Overnight Financing Rate. In addition, the Company includes in its fair value calculation a credit factor adjustment which is based primarily on management judgment. Thus, interest rate swap agreements are classified as a Level 3 measurement. The fair values of foreign exchange contracts are calculated using the Bank’s multi-currency accounting system which utilizes contract specific information such as currency, maturity date, contractual amount, and strike price, along with market data information such as the spot rates of specific currency and yield curves. Foreign exchange contracts are classified as Level 2 measurements because while they are valued using the Bank’s multi-currency accounting system, significant management judgment or estimation is not required. The fair value of the Visa Class B restricted shares to Class A unrestricted common shares conversion rate swap agreements represent the amount owed by the Company to the buyer of the Visa Class B shares as a result of a reduction of the conversion ratio subsequent to the sales date. As of March 31, 2023, and December 31, 2022, the conversion rate swap agreements were valued at zero as reductions to the conversion ratio were neither probable nor reasonably estimable by management. See Note 11 Derivative Financial Instruments for more information. The Company is exposed to credit risk if borrowers or counterparties fail to perform. The Company seeks to minimize credit risk through credit approvals, limits, monitoring procedures, and collateral requirements. The Company generally enters into transactions with borrowers of high credit quality and counterparties that carry high quality credit ratings. Credit risk associated with borrowers or counterparties as well as the Company’s non-performance risk is factored into the determination of the fair value of derivative financial instruments. The Table below presents the balances of assets and liabilities measured at fair value on a recurring basis as of March 31, 2023, and December 31, 2022.

For the three months ended March 31, 2023, and March 31, 2022, the changes in Level 3 assets and liabilities measured at fair value on a recurring basis were as follows: (dollars in thousands) Mortgage 1 Net Derivative 2 Three Months Ended March 31, 2023 Balance as of January 1, 2023 $ 717 $ ( 122,071 ) Realized and Unrealized Net Gains (Losses): Included in Net Income ( 10 ) 336 Transfers to Loans Held for Sale — ( 236 ) Variation Margin Payments — 69,133 Balance as of March 31, 2023 $ 707 $ ( 52,838 ) Total Unrealized Net Gains (Losses) Included in Net Income Related to Assets Still Held as of March 31, 2023 $ — $ 188 Three Months Ended March 31, 2022 Balance as of January 1, 2022 $ 800 $ 23,904 Realized and Unrealized Net Gains (Losses): Included in Net Income 3 ( 19 ) ( 1,085 ) Transfers to Loans Held for Sale — 113 Variation Margin Payments — ( 73,361 ) Balance as of March 31, 2022 $ 781 $ ( 50,429 ) Total Unrealized Net Gains (Losses) Included in Net Income Related to Assets Still Held as of March 31, 2022 $ — $ ( 1,085 ) 1 Realized and unrealized gains and losses related to mortgage servicing rights are reported as a component of mortgage banking income in the Company’s consolidated statements of income. 2 Realized and unrealized gains and losses related to interest rate lock commitments are reported as a component of mortgage banking income in the Company’s consolidated statements of income. Realized and unrealized gains and losses related to interest rate swap agreements are reported as a component of other noninterest income in the Company’s consolidated statements of income. 3 The unrealized net losses included in net income related to assets still held as of March 31, 2022, has been updated to exclude the impact of activities unrelated to the computation of unrealized net losses. For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of March 31, 2023, and December 31, 2022, the significant unobservable inputs used in the fair value measurements were as follows: (dollars in thousands) Valuation Description Range Weighted 1 Fair March 31, 2023 Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 3.28 % - 11.10 % 4.35 % $ 27,163 Discount Rate 8.73 % - 10.42 % 9.84 % $ — Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 84.60 % - 99.00 % 91.50 % $ 174 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.00 % - 0.49 % 0.01 % $ ( 53,012 ) December 31, 2022 Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 2.81 % - 10.63 % 4.02 % $ 28,040 Discount Rate 8.70 % - 10.40 % 9.93 % Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 84.10 % - 99.00 % 92.86 % $ 58 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.00 % - 0.49 % 0.01 % $ ( 122,129 ) 1 Unobservable inputs for mortgage servicing rights and interest rate lock commitments were weighted by loan amount. Unobservable inputs for interest rate swap agreements were weighted by fair value. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions of each other. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company may be required periodically to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets. The following table represents the assets measured at fair value on a nonrecurring basis as of March 31, 2023, and December 31, 2022. (dollars in thousands) Fair Value Net Carrying Valuation March 31, 2023 Mortgage Servicing Rights - amortization method Level 3 $ 21,395 $ — December 31, 2022 Mortgage Servicing Rights - amortization method Level 3 $ 21,902 $ — As previously mentioned, all of the Company's mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Fair Value Option The following table reflects the difference between the aggregate fair value and the aggregate unpaid principal balance of the Company’s residential mortgage loans held for sale as of March 31, 2023, and December 31, 2022. (dollars in thousands) Aggregate Aggregate Aggregate March 31, 2023 Loans Held for Sale $ 2,149 $ 2,135 $ 14 December 31, 2022 Loans Held for Sale $ 1,035 $ 1,016 $ 19 Changes in the estimated fair value of residential mortgage loans held for sale are reported as a component of mortgage banking income in the Company’s consolidated statements of income. For the three months ended March 31, 2023, and year ended December 31, 2022, the net gains or losses from the change in fair value of the Company’s residential mortgage loans held for sale were not material. Financial Instruments Not Recorded at Fair Value on a Recurring Basis The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments not recorded at fair value on a recurring basis as of March 31, 2023, and December 31, 2022. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization.

Summary of the Significant Unobservable Inputs	For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of March 31, 2023, and December 31, 2022, the significant unobservable inputs used in the fair value measurements were as follows: (dollars in thousands) Valuation Description Range Weighted 1 Fair March 31, 2023 Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 3.28 % - 11.10 % 4.35 % $ 27,163 Discount Rate 8.73 % - 10.42 % 9.84 % $ — Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 84.60 % - 99.00 % 91.50 % $ 174 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.00 % - 0.49 % 0.01 % $ ( 53,012 ) December 31, 2022 Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 2.81 % - 10.63 % 4.02 % $ 28,040 Discount Rate 8.70 % - 10.40 % 9.93 % Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 84.10 % - 99.00 % 92.86 % $ 58 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.00 % - 0.49 % 0.01 % $ ( 122,129 ) 1 Unobservable inputs for mortgage servicing rights and interest rate lock commitments were weighted by loan amount. Unobservable inputs for interest rate swap agreements were weighted by fair value.
Schedule of Assets Measured at Fair Value on Nonrecurring Basis	The Company may be required periodically to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets. The following table represents the assets measured at fair value on a nonrecurring basis as of March 31, 2023, and December 31, 2022.

Schedule of Difference between Aggregate Fair Value and Aggregate Unpaid Principal Balance	The following table reflects the difference between the aggregate fair value and the aggregate unpaid principal balance of the Company’s residential mortgage loans held for sale as of March 31, 2023, and December 31, 2022. (dollars in thousands) Aggregate Aggregate Aggregate March 31, 2023 Loans Held for Sale $ 2,149 $ 2,135 $ 14 December 31, 2022 Loans Held for Sale $ 1,035 $ 1,016 $ 19
Schedule of Carrying Amount, Fair Value, and Fair Value Hierarchy of Financial Instruments	The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments not recorded at fair value on a recurring basis as of March 31, 2023, and December 31, 2022. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For non-marketable equity securities such as Federal Home Loan Bank of Des Moines and Federal Reserve Bank stock, the carrying amount is a reasonable estimate of fair value as these securities can only be redeemed or sold at their par value and only to the respective issuing government supported institution or to another member institution. For financial liabilities such as noninterest-bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.
