Mortgage Servicing Rights

9 Months Ended

Sep. 30, 2024

Transfers and Servicing of Financial Assets [Abstract]

Note 5. Mortgage Servicing Rights

The Company’s portfolio of residential mortgage loans serviced for third parties was $2.5 billion as of September 30, 2024 and $2.6 billion as of December 31, 2023. 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 in the Company’s unaudited 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 for both the three months ended September 30, 2024 and 2023, and $4.1 million and $4.2 million for the nine months ended September 30, 2024 and 2023, respectively. Servicing income is recorded in Mortgage Banking in the Company’s unaudited consolidated statements of income. The Company’s residential mortgage investor loan servicing portfolio is primarily comprised of fixed rate loans concentrated in Hawai‘i.

For the three and nine months ended September 30, 2024 and 2023, 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 September 30,						Nine Months Ended September 30,
(dollars in thousands)	2024			2023			2024			2023
Balance at Beginning of Period	$	668		$	695		$	678		$	717
Change in Fair Value Due to Payoffs		(8	)		(10	)		(18	)		(32	)
Balance at End of Period	$	660		$	685		$	660		$	685

For the three and nine months ended September 30, 2024 and 2023, 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 September 30,						Nine Months Ended September 30,
(dollars in thousands)	2024			2023			2024			2023
Balance at Beginning of Period	$	19,286		$	20,931		$	20,201		$	21,902
Servicing Rights that Resulted From Asset Transfers		157			206			316			382
Amortization		(532	)		(549	)		(1,606	)		(1,696	)
Balance at End of Period	$	18,911		$	20,588		$	18,911		$	20,588
Fair Value of Mortgage Servicing Rights Accounted for Under the Amortization Method
Beginning of Period	$	25,326		$	26,327		$	26,173		$	27,323
End of Period	$	25,265		$	26,423		$	25,265		$	26,423

The key data and assumptions used in estimating the fair value of the Company’s mortgage servicing rights as of September 30, 2024 and December 31, 2023, were as follows:


	September 30, 2024			December 31, 2023
Weighted-Average Constant Prepayment Rate 1		4.20	%		4.06	%
Weighted-Average Life (in years)		9.20			9.44
Weighted-Average Note Rate		3.72	%		3.67	%
Weighted-Average Discount Rate 2		9.28	%		9.48	%

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 September 30, 2024 and December 31, 2023, is presented in the following table.


(dollars in thousands)	September 30, 2024			December 31, 2023
Constant Prepayment Rate
Decrease in fair value from 25 basis points (“bps”) adverse change	$	(311	)	$	(326	)
Decrease in fair value from 50 bps adverse change		(615	)		(645	)
Discount Rate
Decrease in fair value from 25 bps adverse change		(291	)		(303	)
Decrease in fair value from 50 bps adverse change		(576	)		(600	)

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.

- Definition

The entire disclosure for a transferor's continuing involvement in financial assets that it has transferred in a securitization or asset-backed financing arrangement, the nature of any restrictions on assets reported by an entity in its statement of financial position that relate to a transferred financial asset (including the carrying amounts of such assets), how servicing assets and servicing liabilities are reported, and (for securitization or asset-backed financing arrangements accounted for as sales) when a transferor has continuing involvement with the transferred financial assets and transfers of financial assets accounted for as secured borrowings, how the transfer of financial assets affects an entity's financial position, financial performance, and cash flows.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Bank of Hawaii Corporation (the “Parent”) is a Delaware corporation and a bank holding company headquartered in Honolulu, Hawai‘i. Bank of Hawai‘i Corporation is a trade name of Bank of Hawaii Corporation, and along with its subsidiaries (collectively, the “Company”), provides a broad range of financial products and services to businesses, consumers and governments in Hawai‘i 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 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, 2023. Significant changes to accounting policies from those disclosed in our audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K are presented below.
Preferred Stock Issuance	Preferred Stock Issuance On June 21, 2024, the Company issued and sold 6,600,000 depositary shares (the “depositary shares”), each representing a 1/40th ownership interest in a share of 8.000% Fixed Rate Non-Cumulative Perpetual Preferred Stock, Series B, par value $0.01 per share (the “Series B Preferred Stock”). The Series B Preferred Stock has a liquidation preference of $1,000 per share. Net proceeds, after underwriting discounts and expenses, totaled $160.6 million. Dividends on the Series B Preferred Stock are not cumulative and will be paid when declared by the Parent’s Board of Directors to the extent that we have legally available funds to pay dividends. If declared, dividends will accrue and be payable quarterly, in arrears, on the liquidation preference amount, on a non-cumulative basis, at a rate of 8.000% per annum. Holders of the Series B Preferred Stock will not have voting rights, except with respect to certain changes in the terms of the preferred stock, certain dividend non-payments and as otherwise required by applicable law. The Company may redeem the Series B Preferred Stock at its option, (i) in whole or in part, from time to time, on any dividend payment date on or after August 1, 2029 or (ii) in whole but not in part, at any time within 90 days following a regulatory capital treatment event, in either case at a redemption price equal to $1,000 per share (equivalent to $25 per depositary share), plus any declared and unpaid dividends.

Derivative Financial Instruments

Note 11. Derivative Financial Instruments

The Company uses derivative instruments to manage its exposure to market risks, including interest rate risk, and to assist customers with their risk management objectives. The Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, while other derivatives serve as economic hedges that do not qualify for hedge accounting.

The notional amount and fair value of the Company’s derivative financial instruments as of September 30, 2024, and December 31, 2023 were as follows:

1 As of September 30, 2024, the amounts presented in the table above excluded forward starting swaps with a notional value of $300 million and a fair value of ($0.1) million. These swaps are scheduled to begin between August 2025 and March 2026 upon maturity of currently active swaps with a notional value of $300 million.

2 The conversion rate swap agreements were valued at zero as further reductions to the conversion rate were not reasonably estimable.

3 The makewhole agreements were valued at zero as the likelihood of a payment required to the counterparty were not reasonably estimable.

The following table presents the Company’s derivative financial instruments, their fair values, and their location in the unaudited consolidated statements of condition as of September 30, 2024 and December 31, 2023:

1 These amounts were included in the fair value of closed portfolios of investment securities, AFS used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. As of September 30, 2024 and December 31, 2023, the fair value of the closed portfolios used in these hedging relationships was $1.7 billion and $1.8 billion, respectively.

2 These amounts were included in the amortized cost basis of closed portfolios of loans used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. As of September 30, 2024 and December 31, 2023 the amortized cost basis of the closed portfolios used in these hedging relationships was $3.0 billion and $3.2 billion, respectively.

Derivatives Not Designated as Hedging Instruments

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 unaudited 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 cash 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 Company had net asset positions with its financial institution counterparties totaling $76.3 million and $114.5 million as of September 30, 2024 and December 31, 2023, 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 September 30, 2024 and December 31, 2023, the conversion rate swap agreement was valued at zero (i.e., no contingent liability recorded) as further reductions to the conversion ratio were deemed not reasonably estimable by management.

Makewhole Agreements

In May 2024, the Company entered into makewhole agreements with certain buyers of its Visa Class B restricted shares that reduces the payments that would be required pursuant to the conversion rate swap agreement described above, but would require payment to the buyer in the event Visa requires additional legal reserves to settle ongoing litigation. As of September 30, 2024, the makewhole agreements were valued at zero (i.e., no contingent liability recorded) as the likelihood of the Company being required to make a payment to the buyer is not reasonably estimable by management.

Derivatives Designated as Hedging Instruments

Fair Value Hedges

The Company is exposed to changes in the fair value of fixed-rate assets due to changes in benchmark interest rates. The Company entered into pay-fixed and receive-floating interest rate swaps to manage its exposure to changes in fair value of its AFS investment securities and fixed rate loans. These interest rate swaps are designated as fair value hedges using the portfolio layer method. The Company receives variable-rate interest payments in exchange for making fixed-rate payments over the lives of the contracts without exchanging the notional amounts. The fair value hedges are recorded as components of other assets and other liabilities in the Company’s unaudited consolidated statements of financial condition. The gain or loss on these derivatives, as well as the offsetting loss or gain on the hedged items attributable to the hedged risk are recognized in interest income in the Company’s unaudited consolidated statements of income.

Credit Quality Indicators

The Company uses several credit quality indicators to manage credit risk in an ongoing manner. 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 generally 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 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 the classes within the commercial portfolio segment that have potential weaknesses that warrant 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 have a well-defined weakness or weaknesses and are inadequately protected by the sound worth and paying capacity of the borrower or applicable collateral, 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 (excluding residential mortgage and home equity loans which meet the criteria for being considered Pass).

For Pass rated credits in the commercial portfolio, most risk ratings are certified at a minimum annually. For Special Mention or Classified credits in the commercial portfolio, 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 September 30, 2024.

Loan Modifications to Borrowers Experiencing Financial Difficulty

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, other-than-insignificant payment delay, or combination thereof. These modifications extend the term of the loan, lower the payment amount, or results in an other-than-insignificant payment delay during a defined period for the purpose of providing borrowers additional time to return to compliance with the original loan term.
Residential Mortgage/ Home Equity:	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/ Home Equity:	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/ Direct Installment:	Term extension greater than three months. These modifications extend the term of the loan, which reduces the monthly payment requirement.

Commitments and Contingencies

Note 12. Commitments and Contingencies

The Company’s credit commitments as of September 30, 2024 and December 31, 2023, were as follows:


(dollars in thousands)	September 30, 2024		December 31, 2023
Unfunded Commitments to Extend Credit	$	3,175,339	$	3,433,061
Standby Letters of Credit		94,841		88,512
Commercial Letters of Credit		11,248		16,551
Total Credit Commitments	$	3,281,428	$	3,538,124

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 $72.5 million secured certain specifically identified standby letters of credit as of September 30, 2024. As of September 30, 2024, the standby and commercial letters of credit had remaining terms ranging from 1 to 19 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 these 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.

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 CECL 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 the Leasing business unit (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 and lease financing, deposit, and brokerage and insurance products; private banking and international client banking services; trust services; investment management; and

institutional investment advisory services. Loan and lease products include residential mortgage loans, home equity lines of credit, automobile loans and leases, overdraft lines of credit, installment loans, small business loans and leases, and credit cards. Deposit products include checking, savings, and time deposit accounts. Brokerage and insurance offerings include equities, mutual funds, life insurance, and annuity products. Private banking (including international client banking) and 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 and the institutional client services group offers investment advice to corporations, government entities, and foundations. Products and services from Consumer Banking are delivered to customers through 50 branch locations and 317 ATMs throughout Hawai‘i and the Pacific Islands, a customer service center, e-Bankoh (online banking service), and a mobile banking service.

Commercial Banking

Commercial Banking offers products including commercial and industrial loans, commercial real estate loans, commercial lease financing, auto dealer financing, merchant services, deposit products and cash management services. Commercial lending and lease financing, deposit products, and cash management and merchant services are offered to middle-market and large companies in Hawai‘i and the Pacific Islands. Commercial Banking also offers lease financing and deposit products to government entities in Hawai‘i. Commercial real estate mortgages focus on investors, developers, and builders predominantly domiciled in Hawai‘i. Commercial Banking includes international banking which services Japanese, Korean, and Chinese commercial businesses owned by a foreign individual or entity, a U.S. corporate subsidiary of a foreign owner, or businesses where management prefers to speak a foreign language.

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 and Other, 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.

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 $221.3 million and $208.9 million as of September 30, 2024 and December 31, 2023, respectively, and are included in Other Assets in the unaudited consolidated statements of condition.

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 and makewhole 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 ("SOFR"). Thus, interest rate swap agreements are classified as a Level 2 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 September 30, 2024 and December 31, 2023, the conversion rate swap agreements were valued at zero as reductions to the conversion ratio were not reasonably estimable by management. See Note 11 Derivative Financial Instruments for more information. The fair value of the makewhole agreements represent the amount owed by the Company to the buyer of the Visa Class B shares in the event Visa requires additional legal reserves to settle ongoing litigation. As of September 30, 2024, the makewhole agreements were valued at zero as the likelihood of the Company being required to make a payment to the buyer is not reasonably estimable by management.

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.

The Table below presents the balances of assets and liabilities measured at fair value on a recurring basis as of September 30, 2024 and December 31, 2023.

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 unaudited consolidated statements of income.

2 Realized and unrealized gains and losses related to IRLCs are reported as a component of mortgage banking income in the Company’s unaudited consolidated statements of income. Realized and unrealized gains and losses related to interest rate swap agreements not designated as hedging

instruments are reported as a component of other noninterest income and interest rate swap agreements designated as hedging instruments are reported in interest

income in the Company’s unaudited consolidated statements of income.

For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of September 30, 2024 and December 31, 2023, the significant unobservable inputs used in the fair value measurements were as follows:



(dollars in thousands)	Valuation Technique	Description	Range					Weighted Average 1			Fair Value
September 30, 2024
Mortgage Servicing Rights	Discounted Cash Flow	Constant Prepayment Rate		3.10	%	-	17.61%		4.20	%	$	25,925
		Discount Rate		8.64	%	-	10.44%		9.28	%
Net Derivative Assets and Liabilities:
Interest Rate Lock Commitments	Pricing Model	Closing Ratio		75.40	%	-	99.00%		91.47	%	$	152
December 31, 2023
Mortgage Servicing Rights	Discounted Cash Flow	Constant Prepayment Rate		2.98	%	-	21.18%		4.06	%	$	26,851
		Discount Rate		7.65	%	-	10.79%		9.48	%
Net Derivative Assets and Liabilities:
Interest Rate Lock Commitments	Pricing Model	Closing Ratio		83.50	%	-	99.00%		85.53	%	$	148

1 Unobservable inputs for mortgage servicing rights and interest rate lock commitments were weighted by loan amount.

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 September 30, 2024 and December 31, 2023.


(dollars in thousands)	Fair Value Hierarchy	Net Carrying Amount		Valuation Allowance
September 30, 2024
Mortgage Servicing Rights - amortization method	Level 3	$	18,911	$	—
December 31, 2023
Mortgage Servicing Rights - amortization method	Level 3	$	20,201	$	—

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 September 30, 2024 and December 31, 2023.


(dollars in thousands)	Aggregate Fair Value		Aggregate Unpaid Principal		Aggregate Fair Value Less Aggregate Unpaid Principal
September 30, 2024
Loans Held for Sale	$	5,048	$	4,980	$	68
December 31, 2023
Loans Held for Sale	$	3,124	$	3,051	$	73

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 unaudited consolidated statements of income. For the three and nine months ended September 30, 2024 and 2023, the net gains or losses from the change in fair value of the Company’s residential mortgage loans held for sale were immaterial.

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 September 30, 2024 and December 31, 2023. 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.

The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities disclosed throughout this footnote. For available-for-sale (“AFS”) debt securities, AIR totaled $8.9 million and $9.0 million as of September 30, 2024 and December 31, 2023, respectively. For held-to-maturity (“HTM”) debt securities, AIR totaled $8.9 million and $8.7 million as of September 30, 2024 and December 31, 2023, respectively. AIR is included in the Accrued Interest Receivable line item on the Company’s unaudited consolidated statements of condition.

The table below presents an analysis of the contractual maturities of the Company’s investment securities as of September 30, 2024. Debt securities issued by government agencies (Small Business Administration securities) and mortgage-backed securities are disclosed separately in the table below as these investment securities may prepay prior to their scheduled contractual maturity dates.

Investment securities with carrying values of $7.0 billion and $7.1 billion as of September 30, 2024 and December 31, 2023, respectively, were pledged to secure deposits of governmental entities, securities sold under agreements to repurchase, and FRB discount window borrowing.

The table below presents the gains and losses from the sales of investment securities for the three and nine months ended September 30, 2024 and 2023:

The losses on sales of investment securities during the three and nine months ended September 30, 2024 and 2023 were due to fees paid to the counterparties of the Company’s prior Visa Class B share sale transactions, which are expensed as incurred. The losses on sales of investment securities during the three months ended September 30, 2023 included a $4.6 million realized loss from sales of various corporate and municipal bonds, a strategic decision made by the Company to reduce the size of its AFS portfolio.

The following table summarizes the Company’s AFS debt securities in an unrealized loss position for which an allowance for credit losses was not deemed necessary, aggregated by major security type and length of time in a continuous unrealized loss position:

The Company does not believe the AFS debt securities that were in an unrealized loss position as of September 30, 2024, which were comprised of 359 individual securities, represent a credit loss impairment. As of September 30, 2024 and December 31, 2023, 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. Mortgage-backed securities issued by U.S. government agencies or U.S. government-sponsored enterprises 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. Debt securities issued by corporations are of high credit quality and the issuers continue to make timely principal and interest payments. 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 September 30, 2024 and December 31, 2023.

Interest income from taxable and non-taxable investment securities for the three and nine months ended September 30, 2024 and 2023 were as follows:

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 in the unaudited consolidated statements of condition 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.

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, Hawai‘i. Bank of Hawai‘i Corporation is a trade name of Bank of Hawaii Corporation, and along with its subsidiaries (collectively, the “Company”), provides a broad range of financial products and services to businesses, consumers and governments in Hawai‘i 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 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, 2023. Significant changes to accounting policies from those disclosed in our audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K are presented below. Preferred Stock Issuance On June 21, 2024, the Company issued and sold 6,600,000 depositary shares (the “depositary shares”), each representing a 1/40th ownership interest in a share of 8.000% Fixed Rate Non-Cumulative Perpetual Preferred Stock, Series B, par value $0.01 per share (the “Series B Preferred Stock”). The Series B Preferred Stock has a liquidation preference of $1,000 per share. Net proceeds, after underwriting discounts and expenses, totaled $160.6 million. Dividends on the Series B Preferred Stock are not cumulative and will be paid when declared by the Parent’s Board of Directors to the extent that we have legally available funds to pay dividends. If declared, dividends will accrue and be payable quarterly, in arrears, on the liquidation preference amount, on a non-cumulative basis, at a rate of 8.000% per annum. Holders of the Series B Preferred Stock will not have voting rights, except with respect to certain changes in the terms of the preferred stock, certain dividend non-payments and as otherwise required by applicable law. The Company may redeem the Series B Preferred Stock at its option, (i) in whole or in part, from time to time, on any dividend payment date on or after August 1, 2029 or (ii) in whole but not in part, at any time within 90 days following a regulatory capital treatment event, in either case at a redemption price equal to $1,000 per share (equivalent to $25 per depositary share), plus any declared and unpaid dividends.
