Organization and Basis of Presentation.
Organization and Basis of Presentation	1. Organization and Basis of Presentation First Hawaiian, Inc. (“FHI” or the “Parent”), a bank holding company, owns 100% of the outstanding common stock of First Hawaiian Bank (“FHB” or the “Bank”), its only direct, wholly owned subsidiary. FHB offers a comprehensive suite of banking services, including loans, deposit products, wealth management, insurance, trust, retirement planning, credit card and merchant processing services, to consumer and commercial customers. The accompanying unaudited interim consolidated financial statements of First Hawaiian, Inc. and Subsidiary (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The accompanying unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s 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. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair presentation of the interim period consolidated financial information, have been made. Results of operations for interim periods are not necessarily indicative of results to be expected for the entire year. Intercompany account balances and transactions have been eliminated in consolidation. Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events, actual results may differ from these estimates. Loan Modifications to Borrowers Experiencing Financial Difficulty Loan modifications are assessed by the Company to determine: (1) whether the borrower is experiencing financial difficulty and (2) whether the Company granted the borrower a modification or combination of modifications in the form of one or more of the following modification types: principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay and/or a term extension. If both criteria are met, then the loan modification is subject to additional evaluation for credit losses and enhanced disclosure requirements. Generally, a non-accrual loan that has been modified with a borrower experiencing financial difficulty remains on non-accrual status for at least six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment terms is uncertain, the loan remains on non-accrual status. Allowance for Credit Losses The allowance for credit losses for loans and leases (the “ACL”) is a valuation account that is deducted from the amortized cost basis of loans and leases to present the net amount expected to be collected from loans and leases. Loans and leases are charged-off against the ACL when management believes the loan or lease balance is deemed uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The Company’s ACL and the reserve for unfunded commitments under the Current Expected Credit Losses (“CECL”) approach consist of quantitative and qualitative estimates. The Company’s methodology leverages two quantitative models: a one-variable forward-looking macroeconomic model that estimates the impact of management’s economic outlook and a transition probability matrix that estimates expected losses over the long run. The quantitative estimation is overlaid with qualitative adjustments to account for current conditions and forward-looking factors not captured in the quantitative model. Qualitative adjustments that are considered include adjustments for regulatory determinants, model limitations, model maturity, and other current or anticipated events that are not captured in the Company’s historical loss experience. The Company generally evaluates loans and leases on a collective or pool basis when similar risk characteristics exist. However, loans and leases that do not share similar risk characteristics are evaluated on an individual basis. Such loans and leases evaluated individually are excluded from the collective evaluation. Individually assessed loans are measured for estimated credit loss (“ECL”) based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral, less estimated selling costs, if the loan is collateral-dependent. Management reviews relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts about the future. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency levels, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The Company utilizes a Probability of Default (“PD”)/Loss Given Default (“LGD”) framework to estimate the ACL and the reserve for unfunded commitments. The PD represents the percentage expectation to default, measured by assessing loans and leases that migrate to default status (i.e., nonaccrual status, 90 days or more past due, partial or full charge-offs or bankruptcy). LGD is defined as the percentage of the exposure at default (“EAD”) lost at the time of default, net of any recoveries, and will be unique to each of the collateral types securing the Company’s loans. PD and LGD’s are based on past experience of the Company. The ECL on loans and leases is calculated by taking the product of the credit exposure, lifetime default probability (“LDP”) and the LGD. The ECL model is applied to current credit exposures at the account level, using assumptions calibrated at the portfolio segment level using internal historical loan and lease level data. The Company estimates the default risk of a credit exposure over the remaining life of each account using a transition probability matrix approach which captures both the average rate of up/down-grade and default transitions, as well as withdrawal rates which capture the historical rate of exposure decline due to loan and lease amortization and prepayment. To apply the transition matrices, each credit exposure’s remaining life is split into two time segments. The first time segment is for the reasonable and supportable forecast period over which the transition matrices which are applied have been adjusted to incorporate current and forecasted conditions over that period. Management has determined that using a one-year time horizon for the reasonable and supportable forecast period for all classes of loans and leases is a reasonable forecast horizon given the difficulty in predicting future economic conditions with a high degree of certainty. The second time segment is the reversion period from the end of the reasonable and supportable forecast period to the maturity of the exposure, over which long-run average transition matrices are applied. Management elected to use an immediate reversion to the mean approach. Lifetime loss rates are applied against the amortized cost basis of loans and leases and unfunded commitments to estimate the ACL and the reserve for unfunded commitments, respectively. On at least a quarterly basis, management convenes the Bank’s forecasting team which is responsible for reviewing the economic forecast model inputs and outputs and approving the resulting economic adjustment. The model uses a one-variable econometric model to produce factors that modify the long-run default rate assumptions used in the CECL model. These factors are applied to calculate the economic adjustment over the Reasonable and Supportable Forecast Period. At the meeting, management is presented with the economic forecast model input and output as well as the resulting economic adjustment. Depending on the current economic conditions, a range of inputs and outputs may be presented, in which case, using judgment, management will select an input and output. The economic forecast framework also allows management to use judgment in selecting the economic model input in cases where management’s outlook diverges from the official forecasts, and to apply qualitative dollar overlays to account for other economic related conditions not captured in the economic forecast model but are expected to potentially impact losses. The team also reviews other relevant economic variables and economic factors at the time of the meeting that could potentially impact future losses. These materials are presented to the economic forecasting team as they are economic in nature. If determined to be relevant and needing to be considered in the ACL estimate, these risks will be included in the ACL estimate through a qualitative dollar overlay that is determined using either quantitative analysis or qualitative judgment, or a mix of both. These other factors could include inflation indicators, personal income, or visitor arrivals, for example. At present, the Company has identified three portfolio segments in estimating the ACL: commercial, residential real estate and consumer lending. The Company’s commercial portfolio segment is comprised of four distinct classes: commercial and industrial loans, commercial real estate loans, construction loans and lease financing. The key risk drivers related to this portfolio segment include risk rating, collateral type, and remaining maturity. The Company’s residential real estate portfolio segment is comprised of two distinct classes: residential real estate loans and home equity lines of credit. Specific risk characteristics related to this portfolio include the value of the underlying collateral, credit score and remaining maturity. Finally, the Company’s consumer portfolio segment is not further segmented, but consists primarily of automobile loans, credit cards and other installment loans. Automobile loans constitute the majority of this segment and are monitored using credit scores, collateral values and remaining maturity. The remainder of the consumer portfolio is predominantly unsecured. Regarding accrued interest receivable, the Company made accounting policy elections to (1) not measure an ACL on accrued interest receivable, (2) write-off accrued interest receivable by reversing interest income and (3) present accrued interest receivable separately from the related financial asset on the balance sheet. Furthermore, regarding collateral-dependent financial assets, the Company elected the practical expedient to use the fair value of collateral at the reporting date when recording the net carrying amount of the asset and determining the ACL for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Company’s assessment as of the reporting date. Accounting Standards Adopted in 2023 In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-01, Derivatives and Hedging (Topic 815), Fair Value Hedging –Portfolio Layer Method. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures Enactment of the Inflation Reduction Act of 2022 On August 16, 2022, the U.S. government enacted the Inflation Reduction Act (IRA) which, among other changes, created a new corporate alternative minimum tax (AMT) based on adjusted financial statement income and imposes a 1% excise tax on corporate stock repurchases. These provisions became effective January 1, 2023. The enactment of the IRA did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements The following ASUs have been issued by the FASB and are applicable to the Company in future reporting periods. In March 2023, the FASB issued ASU No. 2023-01, Leases (Topic 842), Common Control Arrangements. Property, Plant, and Equipment.

Amortized cost, gross unrealized holding gains and losses and fair value of available-for-sale and held-to-maturity investment securities as of September 30, 2023 and December 31, 2022 were as follows: September 30, 2023 December 31, 2022 Amortized Unrealized Unrealized Fair Amortized Unrealized Unrealized Fair (dollars in thousands) Cost Gains Losses Value Cost Gains Losses Value U.S. Treasury and government agency debt securities $ 126,264 $ — $ (12,105) $ 114,159 $ 163,309 $ — $ (12,327) $ 150,982 Government-sponsored enterprises debt securities 20,000 — (740) 19,260 45,000 — (699) 44,301 Mortgage-backed securities: Residential - Government agency 61,768 — (9,406) 52,362 66,792 — (7,069) 59,723 Residential - Government-sponsored enterprises 1,185,269 — (179,487) 1,005,782 1,317,718 — (157,263) 1,160,455 Commercial - Government agency 272,432 — (60,535) 211,897 282,700 — (44,847) 237,853 Commercial - Government-sponsored enterprises 94,021 — (9,101) 84,920 130,612 — (11,039) 119,573 Commercial - Non-agency 21,964 — (362) 21,602 21,964 — (493) 21,471 Collateralized mortgage obligations: Government agency 661,207 — (95,355) 565,852 738,524 — (85,202) 653,322 Government-sponsored enterprises 479,217 — (78,469) 400,748 533,103 — (70,971) 462,132 Collateralized loan obligations 249,889 21 (3,788) 246,122 249,877 50 (8,606) 241,321 Total available-for-sale securities $ 3,172,031 $ 21 $ (449,348) $ 2,722,704 $ 3,549,599 $ 50 $ (398,516) $ 3,151,133 Government agency debt securities $ 53,105 $ — $ (7,901) $ 45,204 $ 54,318 $ — $ (5,674) $ 48,644 Mortgage-backed securities: Residential - Government agency 44,379 — (8,024) 36,355 46,302 — (6,294) 40,008 Residential - Government-sponsored enterprises 100,905 — (18,151) 82,754 106,534 — (12,978) 93,556 Commercial - Government agency 30,733 — (8,756) 21,977 30,544 — (5,229) 25,315 Commercial - Government-sponsored enterprises 1,132,818 153 (194,471) 938,500 1,150,449 — (138,451) 1,011,998 Collateralized mortgage obligations: Government agency 1,010,551 — (153,260) 857,291 1,080,492 — (122,378) 958,114 Government-sponsored enterprises 1,677,519 — (271,248) 1,406,271 1,798,178 — (207,045) 1,591,133 Debt securities issued by states and political subdivisions 54,104 — (9,427) 44,677 53,822 — (7,768) 46,054 Total held-to-maturity securities $ 4,104,114 $ 153 $ (671,238) $ 3,433,029 $ 4,320,639 $ — $ (505,817) $ 3,814,822 During the year ended December 31, 2022, the Company reclassified at fair value approximately $4.6 billion, in available-for-sale investment securities to the held-to-maturity category. The related total unrealized after-tax losses of approximately $372.4 million remained in accumulated other comprehensive loss to be amortized over the estimated remaining life of the securities as an adjustment of yield, offsetting the related accretion of the discount on the transferred securities. No gains or losses were recognized at the time of reclassification. Management considers the held-to-maturity classification of these investment securities to be appropriate as the Company has the positive intent and ability to hold these securities to maturity. There were no securities transferred from available-for-sale investment securities to the held-to-maturity category during the three and nine months ended September 30, 2023. Accrued interest receivable related to available-for-sale investment securities was $8.7 million and $8.9 million as of September 30, 2023 and December 31, 2022, respectively. Accrued interest receivable related to held-to-maturity investment securities was $7.4 million and $7.5 million as of September 30, 2023 and December 31, 2022, respectively. Accrued interest receivable is recorded separately from the amortized cost basis of investment securities on the Company’s unaudited interim consolidated balance sheets. Proceeds from calls and sales of investment securities were $0.2 million and nil, respectively, for the three months ended September 30, 2023, and $8.0 million and $25.2 million, respectively, for the nine months ended September 30, 2023. Proceeds from calls and sales of investment securities were $0.3 million and nil, respectively, for the three months ended September 30, 2022, and $1.5 million and nil, respectively, for the nine months ended September 30, 2022. The Company recorded gross realized gains of nil and gross realized losses of nil for the three and nine months ended September 30, 2023 and 2022. The income tax expense related to the Company’s net realized gain on the sale of investment securities was nil for the three and nine months ended September 30, 2023 and 2022. Gains and losses realized on sales of securities are determined using the specific identification method. Interest income from taxable investment securities was $33.4 million and $33.8 million, respectively, for the three months ended September 30, 2023 and 2022, and $100.7 million and $94.5 million, respectively, for the nine months ended September 30, 2023 and 2022. Interest income from non-taxable investment securities was $3.3 million and $3.8 million, respectively, for the three months ended September 30, 2023 and 2022, and $10.0 million and $10.1 million, respectively, for the nine months ended September 30, 2023 and 2022. The amortized cost and fair value of debt securities issued by the U.S. Treasury, government agencies, government-sponsored enterprises and states and political subdivisions, non-agency mortgage-backed securities and collateralized loan obligations as of September 30, 2023, by contractual maturity, are shown below. Mortgage-backed securities and collateralized mortgage obligations issued by government agencies and government-sponsored enterprises are disclosed separately in the table below as remaining expected maturities will differ from contractual maturities as borrowers have the right to prepay obligations.

At December 31, 2022, pledged securities totaled $3.2 billion, of which $3.0 billion was pledged to secure public deposits and $207.8 million was pledged to secure other financial transactions. The Company held no securities of any single issuer, other than debt securities issued by the U.S. government, government agencies and government-sponsored enterprises, taken in the aggregate, which were in excess of 10% of stockholders’ equity as of September 30, 2023 or December 31, 2022. The following tables present the unrealized gross losses and fair values of securities in the available-for-sale portfolio by length of time that the 279 and 275 individual securities in each category have been in a continuous loss position as of September 30, 2023 and December 31, 2022, respectively. The unrealized losses on available-for-sale investment securities 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.

As the Company had the intent and ability to hold the remaining available-for-sale securities in an unrealized loss position as of September 30, 2023 and December 31, 2022, each security with an unrealized loss position in the above tables has been further assessed to determine if a credit loss exists. As of September 30, 2023 and December 31, 2022, the Company did not expect any credit losses in its available-for-sale debt securities and no credit losses were recognized on available-for-sale securities during the three and nine months ended September 30, 2023 and for the year ended December 31, 2022. As of September 30, 2023 and December 31, 2022, the Company’s investment securities were comprised primarily of debt securities, mortgage-backed securities and collateralized mortgage obligations issued by the U.S. Government, its agencies and government-sponsored enterprises, with under 5% of the investment securities comprised of collateralized loan obligations rated AA or better and obligations issued by local state and political subdivisions rated AA or better. For investment securities issued by the U.S. Government, its agencies and government-sponsored enterprises, management has concluded that the long history with no credit losses from these issuers indicates an expectation that nonpayment of the amortized cost basis is zero, and these securities are explicitly or implicitly fully guaranteed by the U.S. government. The U.S. government can print its own currency and its currency is routinely held by central banks and other major financial institutions. The dollar is used in international commerce, and commonly is viewed as a reserve currency, all of which qualitatively indicates that historical credit loss information should be minimally affected by current conditions and reasonable and supportable forecasts. For collateralized loan obligations and debt securities issued by local state and political subdivisions, these securities are investment grade and highly rated and carry either sufficient credit enhancement or days cash on hand to support timely payments of principal and interest. As a result, the Company does not expect any future payment defaults and has not recorded an allowance for credit losses for its available-for-sale and held-to-maturity debt securities as of September 30, 2023 or December 31, 2022. The Company held approximately 120,000 Visa Class B restricted shares as of both September 30, 2023 and December 31, 2022. These shares continued to be carried at $0 cost basis as of both September 30, 2023 and December 31, 2022.

Loans and Leases As of September 30, 2023 and December 31, 2022, loans and leases were comprised of the following: September 30, December 31, (dollars in thousands) 2023 2022 Commercial and industrial $ 2,101,442 $ 2,235,897 Commercial real estate 4,387,751 4,132,309 Construction 885,112 844,643 Residential: Residential mortgage 4,303,924 4,302,788 Home equity line 1,167,388 1,055,351 Total residential 5,471,312 5,358,139 Consumer 1,154,203 1,222,934 Lease financing 332,515 298,090 Total loans and leases $ 14,332,335 $ 14,092,012 As of September 30, 2023, commercial real estate and residential real estate loans totaling $4.8 billion were pledged to collateralize the Company’s borrowing capacity at the Federal Home Loan Bank of Des Moines (“FHLB”), and consumer, commercial and industrial, commercial real estate, residential real estate loans and pledged securities totaling $4.8 billion were pledged to collateralize the Company’s borrowing capacity at the Federal Reserve Bank of San Francisco (“FRB”). As of December 31, 2022, residential real estate loans totaling $3.5 billion were pledged to collateralize the Company’s borrowing capacity at the FHLB, and consumer, commercial and industrial, commercial real estate and residential real estate loans totaling $1.7 billion were pledged to collateralize the Company’s borrowing capacity at the FRB. Residential real estate loans collateralized by properties that were in the process of foreclosure totaled $7.3 million and $2.8 million as of September 30, 2023 and December 31, 2022, respectively. In the course of evaluating the credit risk presented by a customer and the pricing that will adequately compensate the Company for assuming that risk, management may require a certain amount of collateral support. The type of collateral held varies, but may include accounts receivable, inventory, land, buildings, equipment, income-producing commercial properties and residential real estate. The Company applies the same collateral policy for loans whether they are funded immediately or on a delayed basis. The loan and lease portfolio is principally located in Hawaii and, to a lesser extent, on the U.S. Mainland, Guam and Saipan. The risk inherent in the portfolio depends upon both the economic strength and stability of the state or territories, which affects property values, and the financial strength and creditworthiness of the borrowers.

Allowance for Credit Losses

Allowance for Credit Losses
Allowance for Credit Losses	4. Allowance for Credit Losses The Company maintains the ACL that is deducted from the amortized cost basis of loans and leases to present the net carrying value of loans and leases expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of loans and leases. While management utilizes its best judgment and information available, the ultimate appropriateness of the ACL is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. The Company’s methodology is more fully described in our Annual Report on Form 10-K for the year ended December 31, 2022.

The review provides management with periodic information as to the quality of the loan portfolio and effectiveness of the Company’s lending policies and procedures. The objective of the loan review and grading or scoring procedures is to identify, in a timely manner, existing or emerging credit quality issues so that appropriate steps can be initiated to avoid or minimize future losses. Loans and leases subject to grading primarily include: commercial and industrial loans, commercial real estate loans, construction loans and lease financing. Other loans subject to grading include installment loans to businesses or individuals for business and commercial purposes, overdraft lines of credit, commercial credit cards, and other credits as may be determined. Credit quality indicators for internally graded loans and leases are generally updated on an annual basis or on a quarterly basis for those loans and leases deemed to be of potentially higher risk. An internal credit risk rating system is used to determine loan grade and is based on borrower credit risk and transactional risk. The loan grading process is a mechanism used to determine the risk of a particular borrower and is based on the following factors of a borrower: character, earnings and operating cash flow, asset and liability structure, debt capacity, management and controls, borrowing entity, and industry and operating environment. Pass Special Mention Substandard Doubtful Loss Loans that are primarily monitored for credit quality using FICO scores include: residential mortgage loans, home equity lines and consumer loans. FICO scores are calculated primarily based on a consideration of payment history, the current amount of debt, the length of credit history available, a recent history of new sources of credit and the mix of credit type. FICO scores are updated on a monthly, quarterly or bi-annual basis, depending on the product type.

Loans and leases of this nature are primarily secured by collateral and/or are closely monitored for performance. There were no loans and leases graded as Loss as of September 30, 2023 and December 31, 2022. Past-Due Status The Company continually updates its aging analysis for loans and leases to monitor the migration of loans and leases into past due categories. The Company considers loans and leases that are delinquent for 30 days or more to be past due. As of September 30, 2023 and December 31, 2022, the aging analysis of the amortized cost basis of the Company’s past due loans and leases was as follows: September 30, 2023 Past Due Loans and Greater Leases Past Than or Due 90 Days 30-59 60-89 Equal to or More and Days Days 90 Days Total Total Loans Still Accruing (dollars in thousands) Past Due Past Due Past Due Past Due Current and Leases Interest Commercial and industrial $ 3,989 $ 673 $ 1,277 $ 5,939 $ 2,095,503 $ 2,101,442 $ 289 Commercial real estate — 300 170 470 4,387,281 4,387,751 170 Construction — — — — 885,112 885,112 — Lease financing — — — — 332,515 332,515 — Residential mortgage 3,239 — 6,575 9,814 4,294,110 4,303,924 1,430 Home equity line 6,741 938 3,320 10,999 1,156,389 1,167,388 — Consumer 20,327 3,967 1,681 25,975 1,128,228 1,154,203 1,681 Total $ 34,296 $ 5,878 $ 13,023 $ 53,197 $ 14,279,138 $ 14,332,335 $ 3,570 December 31, 2022 Past Due Loans and Greater Leases Past Than or Due 90 Days 30-59 60-89 Equal to or More and Days Days 90 Days Total Total Loans Still Accruing (dollars in thousands) Past Due Past Due Past Due Past Due Current and Leases Interest Commercial and industrial $ 2,682 $ 769 $ 1,441 $ 4,892 $ 2,231,005 $ 2,235,897 $ 291 Commercial real estate 4,505 — 727 5,232 4,127,077 4,132,309 — Construction 109 — — 109 844,534 844,643 — Lease financing — — — — 298,090 298,090 — Residential mortgage 3,681 1,983 2,572 8,236 4,294,552 4,302,788 58 Home equity line 5,161 1,381 2,072 8,614 1,046,737 1,055,351 — Consumer 29,927 6,801 2,886 39,614 1,183,320 1,222,934 2,885 Total $ 46,065 $ 10,934 $ 9,698 $ 66,697 $ 14,025,315 $ 14,092,012 $ 3,234 Nonaccrual Loans and Leases The Company generally places a loan or lease on nonaccrual status when management believes that collection of principal or interest has become doubtful or when a loan or lease becomes 90 days past due as to principal or interest, unless it is well secured and in the process of collection. The Company charges off a loan or lease when facts indicate that the loan or lease is considered uncollectible. The amortized cost basis of loans and leases on nonaccrual status as of September 30, 2023 and December 31, 2022 and the amortized cost basis of loans and leases on nonaccrual status with no ACL as of September 30, 2023 and December 31, 2022 were as follows: September 30, 2023 Nonaccrual Loans and Leases With No Nonaccrual Allowance Loans (dollars in thousands) for Credit Losses and Leases Commercial and industrial $ 503 $ 988 Residential mortgage 2,674 7,435 Home equity line 596 6,200 Total Nonaccrual Loans and Leases $ 3,773 $ 14,623 December 31, 2022 Nonaccrual Loans and Leases With No Nonaccrual Allowance Loans (dollars in thousands) for Credit Losses and Leases Commercial and industrial $ 665 $ 1,215 Commercial real estate 727 727 Residential mortgage 1,560 6,166 Home equity line 596 3,797 Total Nonaccrual Loans and Leases $ 3,548 $ 11,905 For the three and nine months ended September 30, 2023, the Company recognized interest income of $0.1 million and $0.4 million, respectively, on nonaccrual loans and leases, and for the three and nine months ended September 30, 2022, the Company recognized interest income of $0.1 million and $0.2 million, respectively, on nonaccrual loans and leases. Furthermore, for the three and nine months ended September 30, 2023, the amount of accrued interest receivables written off by reversing interest income was $0.2 million and $0.7 million, respectively, and for the three and nine months ended September 30, 2022 the amount of accrued interest receivables written off by reversing interest income was $0.3 million and $0.7 million, respectively. Collateral-Dependent Loans and Leases Collateral-dependent loans and leases are those for which repayment (on the basis of the Company’s assessment as of the reporting date) is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. As of September 30, 2023 and December 31, 2022, the amortized cost basis of collateral-dependent loans were $7.5 million and $8.2 million, respectively. As of both September 30, 2023 and December 31, 2022, these loans were primarily collateralized by residential real estate property and the fair value of collateral on substantially all collateral-dependent loans were significantly in excess of their amortized cost basis. Loan Modifications to Borrowers Experiencing Financial Difficulty The Company adopted the provisions of Accounting Standards Update (“ASU”) No. 2022-02, Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures

Mortgage Servicing Rights	5. Mortgage Servicing Rights Mortgage servicing activities include collecting principal, interest, tax, and insurance payments from borrowers while accounting for and remitting payments to investors, taxing authorities, and insurance companies. The Company also monitors delinquencies and administers foreclosure proceedings. Mortgage loan servicing income is recorded in noninterest income as a part of other service charges and fees and amortization of the servicing assets is recorded in noninterest income as part of other income. The unpaid principal amount of residential real estate loans serviced for others was $1.4 billion as of both September 30, 2023 and December 31, 2022. Servicing fees include contractually specified fees, late charges, and ancillary fees and were $0.8 million and $0.9 million for the three months ended September 30, 2023 and 2022, respectively, and $2.6 million and $2.9 million for the nine months ended September 30, 2023 and 2022, respectively. Amortization of mortgage servicing rights (“MSRs”) was $0.3 million for both three months ended September 30, 2023 and 2022, and $0.8 million and $1.6 million for the nine months ended September 30, 2023 and 2022, respectively. The estimated future amortization expenses for MSRs over the next five years are as follows: Estimated (dollars in thousands) Amortization Under one year $ 852 One to two years 757 Two to three years 671 Three to four years 592 Four to five years 523 The details of the Company’s MSRs are presented below: September 30, December 31, (dollars in thousands) 2023 2022 Gross carrying amount $ 69,406 $ 69,273 Less: accumulated amortization 63,551 62,711 Net carrying value $ 5,855 $ 6,562 The following table presents changes in amortized MSRs for the three and nine months ended September 30, 2023 and 2022: Three Months Ended September 30, Nine Months Ended September 30, (dollars in thousands) 2023 2022 2023 2022 Balance at beginning of period $ 6,072 $ 7,152 $ 6,562 $ 8,302 Originations 65 47 133 151 Amortization (282) (333) (840) (1,587) Balance at end of period $ 5,855 $ 6,866 $ 5,855 $ 6,866 Fair value of amortized MSRs at beginning of period $ 14,557 $ 14,969 $ 15,193 $ 12,243 Fair value of amortized MSRs at end of period $ 14,520 $ 14,945 $ 14,520 $ 14,945 MSRs are evaluated for impairment if events and circumstances indicate a possible impairment. No impairment of MSRs was recorded for the three and nine months ended September 30, 2023 and 2022. The quantitative assumptions used in determining the lower of cost or fair value of the Company’s MSRs as of September 30, 2023 and December 31, 2022 were as follows: September 30, 2023 December 31, 2022 Weighted Weighted Range Average Range Average Conditional prepayment rate 6.89 % - 11.27 % 7.02 % 7.02 % - 13.58 % 7.11 % Life in years (of the MSR) 4.26 - 7.25 7.11 3.35 - 7.37 7.20 Weighted-average coupon rate 3.57 % - 5.84 % 3.70 % 3.55 % - 6.24 % 3.68 % Discount rate 10.36 % - 10.55 % 10.52 % 10.41 % - 10.54 % 10.51 % The sensitivities surrounding MSRs are expected to have an immaterial impact on fair value.

Transfers of Financial Assets
Transfers of Financial Assets	6. Transfers of Financial Assets The Company’s transfers of financial assets with continuing interest may include pledges of collateral to secure public deposits and repurchase agreements, FHLB and FRB borrowing capacity, automated clearing house (“ACH”) transactions and interest rate swaps. For public deposits and repurchase agreements, the Company enters into bilateral agreements with the entity to pledge investment securities as collateral in the event of default. The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral pledged by the Company would be used to settle the fair value of the repurchase agreement should the Company be in default. The counterparty has the right to sell or repledge the investment securities. The Company is required by the counterparty to maintain adequate collateral levels. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional investment securities. For transfers of assets with the FHLB and the FRB, the Company enters into bilateral agreements to pledge loans and/or securities as collateral to secure borrowing capacity. For ACH transactions, the Company enters into bilateral agreements to collateralize possible daylight overdrafts. For interest rate swaps, the Company enters into bilateral agreements to pledge collateral when either party is in a negative fair value position to mitigate counterparty credit risk. Counterparties to ACH transactions, certain interest rate swaps, the FHLB and the FRB do not have the right to sell or repledge the collateral. The carrying amounts of the assets pledged as collateral to secure public deposits, borrowing arrangements and other transactions as of September 30, 2023 and December 31, 2022 were as follows: (dollars in thousands) September 30, 2023 December 31, 2022 Public deposits $ 3,511,412 $ 2,977,693 Federal Home Loan Bank 4,817,865 3,451,070 Federal Reserve Bank 4,801,873 1,704,803 ACH transactions 135,512 133,173 Interest rate swaps 585 31,091 Total $ 13,267,247 $ 8,297,830 As the Company did not enter into reverse repurchase agreements or repurchase agreements, no collateral was accepted as of September 30, 2023 and December 31, 2022. In addition, no debt was extinguished by in-substance defeasance.

Regulatory Capital Requirements
Regulatory Capital Requirements	10. Regulatory Capital Requirements Federal and state laws and regulations limit the amount of dividends the Company may declare or pay. The Company depends primarily on dividends from FHB as the source of funds for the Company’s payment of dividends. The Company and the Bank are subject to various regulatory capital requirements imposed by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s operating activities and financial condition. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of its assets and certain off-balance sheet items. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The table below sets forth those ratios at September 30, 2023 and December 31, 2022: First Hawaiian Minimum Well- First Hawaiian, Inc.

Federal regulations require a 2.5% capital conservation buffer designed to absorb losses during periods of economic stress. The capital conservation buffer is composed entirely of CET1, on top of these minimum risk weighted asset ratios, effectively resulting in minimum ratios of (i) 7% CET1 to risk-weighted assets, (ii) 8.5% Tier 1 capital to risk-weighted assets, and (iii) 10.5% total capital to risk-weighted assets. As of September 30, 2023, under the bank regulatory capital guidelines, the Company and Bank were both classified as well-capitalized. Management is not aware of any conditions or events that have occurred since September 30, 2023, to change the capital adequacy category of the Company or the Bank.

Derivative Financial Instruments
Derivative Financial Instruments	11. Derivative Financial Instruments The Company enters into derivative contracts primarily to manage its interest rate risk, as well as for customer accommodation purposes. Derivatives used for risk management purposes consist of interest rate swaps and collars that are designated as either a fair value hedge or a cash flow hedge. The derivatives are recognized on the unaudited interim consolidated balance sheets as either assets or liabilities at fair value. Derivatives entered into for customer accommodation purposes consist of various free-standing interest rate derivative products and foreign exchange contracts. 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 following table summarizes the notional amounts and fair values of derivatives held by the Company as of September 30, 2023 and December 31, 2022: September 30, 2023 December 31, 2022 Fair Value Fair Value Notional Asset Liability Notional Asset Liability (dollars in thousands) Amount Derivatives (1) Derivatives (2) Amount Derivatives (1) Derivatives (2) Derivatives designated as hedging instruments: Interest rate swaps $ 267,500 $ 9,829 $ (3,731) $ 267,500 $ 7,276 $ (6,840) Interest rate collars 200,000 — (951) 200,000 491 (63) Derivatives not designated as hedging instruments: Interest rate swaps 2,811,284 3,073 (1,198) 2,849,776 3,178 (42,365) Visa derivative 102,587 — (1,200) 121,013 — (851) Foreign exchange contracts 191 — — 210 — — (1) The positive fair values of derivative assets are included in other assets . (2) The negative fair values of derivative liabilities are included in other liabilities . Certain interest rate swaps noted above, are cleared through clearinghouses, rather than directly with counterparties. Those transactions cleared through a clearinghouse require initial margin collateral and variation margin payments depending on the contracts being in a net asset or liability position. As of September 30, 2023 and December 31, 2022, the amount of initial margin cash collateral posted by the Company was $0.6 million and $1.2 million, respectively. As of September 30, 2023 and December 31, 2022, the variation margin was $1.9 million and $39.2 million, respectively. As of September 30, 2023, the Company pledged $0.6 million in cash and received $49.1 million in cash as collateral for interest rate swaps. As of December 31, 2022, the Company pledged $29.9 million in financial instruments and $1.2 million in cash and received $48.1 million in cash as collateral for interest rate swaps. As of September 30, 2023 and December 31, 2022, the cash collateral includes the excess initial margin for interest rate swaps cleared through clearinghouses and cash collateral for interest rate swaps with financial institution counterparties. As of September 30, 2023 and December 31, 2022, the Company received $68.5 million and nil, respectively, in securities collateral for interest rate swaps, which is held in a custodial account and is not recorded on the Company’s unaudited interim consolidated balance sheets. Fair Value Hedges To manage the risk related to the Company’s net interest margin, interest rate swaps are utilized to hedge certain fixed-rate loans. These swaps have maturity, amortization and prepayment features that correspond to the loans hedged, and are designated and qualify as fair value hedges. Any gain or loss on the swaps, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, is recognized in current period earnings. At September 30, 2023 and December 31, 2022, the Company carried one interest rate swap with a notional amount of $67.5 million, which was designated and qualified as a fair value hedge for a commercial and industrial loan. As of September 30, 2023 and December 31, 2022, the interest rate swap had a positive fair value of $9.8 million and $7.3 million, respectively. The swap matures in 2041. The Company received a USD Federal Funds floating rate and paid a fixed rate of 2.07% . The following table shows the gains and losses recognized in income related to derivatives in fair value hedging relationships for the three and nine months ended September 30, 2023 and 2022: Gains (losses) recognized in Three Months Ended Nine Months Ended the consolidated statements September 30, September 30, (dollars in of income line item 2023 2022 2023 2022 Gains (losses) on fair value hedging relationships recognized in interest income: Recognized on interest rate swap Loans and lease financing $ 2,159 $ 745 $ 2,553 $ 6,888 Recognized on hedged item Loans and lease financing (2,256) (839) (2,833) (7,185) As of September 30, 2023 and December 31, 2022, the following amounts were recorded in the unaudited interim consolidated balance sheets related to the cumulative basis adjustments for fair value hedges: Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Asset Carrying Amount of the Hedged Asset (dollars in September 30, 2023 December 31, 2022 September 30, 2023 December 31, 2022 Line item in the consolidated balance sheets in which the hedged item is included Loans and leases $ 57,627 $ 60,189 $ (9,873) $ (7,311) Cash Flow Hedges The Company utilized interest rate swaps to reduce asset sensitivity and enhance current yields associated with interest payments received on a pool of floating-rate loans. The Company entered into interest rate swaps paying floating rates and receiving fixed rates. The floating-rate index (Bloomberg Short-Term Bank Yield Index, or “BSBY”) corresponds to the floating-rate nature of the interest receipts being hedged (based on USD Prime). The swaps provided an initial benefit to interest income as the Company received the higher fixed rate, which persisted while the floating rate remained below the swap’s fixed rate. By hedging with interest rate swaps, the Company minimized the adverse impact on interest income previously associated with a low interest rate environment on floating-rate loans. As of September 30, 2023 and December 31, 2022, the Company carried two interest rate swaps with notional amounts totaling $200.0 million, with a negative fair value totaling $3.7 million and $6.8 million, respectively. The swaps mature in 2024. The Company received fixed rates ranging from 1.70% to 2.08% and paid 1-month BSBY. The Company also utilized interest rate collars to manage interest rate risk and protect against downside risk in yields associated with interest payments received on a pool of floating-rate assets. The floating-rate index of the collars (Secured Overnight Financing Rate, or “SOFR”) corresponds to the floating-rate nature of the interest receipts being hedged (based on SOFR). Interest rate collars involve the payments of variable-rate amounts if the collar index exceeds the cap strike rate on the contract and receipts of variable-rate amounts if the collar index falls below the floor strike rate on the contract. No payments are required if the collar index falls between the cap and floor rates. By hedging with interest rate collars, the Company mitigates the adverse impact on interest income associated with possible future decreases in interest rates. As of September 30, 2023 and December 31, 2022, the Company carried two interest rate collars with notional amounts totaling $200.0 million. As of September 30, 2023, these interest rate collars had a negative fair value of $1.0 million. As of December 31, 2022, these interest rate collars had a positive fair value of $0.5 million and a negative fair value of $0.1 million. The collars mature in 2025 and 2027. The interest rate collars had a floor strike rate of 2.00% and cap strike rates ranging from 5.31% to 5.64%. The interest rate swaps and collars are designated and qualify as cash flow hedges. To the extent that the hedge is considered highly effective, the gain or loss on the interest rate swaps and collars is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period that the hedged transaction affects earnings. The following table summarizes the effect of cash flow hedging relationships for the three and nine months ended September 30, 2023 and 2022: Three Months Ended Nine Months Ended September 30, September 30, (dollars in 2023 2022 2023 2022 Pretax net losses recognized in other comprehensive income on cash flow derivative hedges $ (373) $ (4,372) $ (2,868) $ (7,611) Pretax net losses (gains) reclassified from accumulated other comprehensive income to interest income from loans and lease financing 1,723 98 4,599 (540) The estimated net amount to be reclassified within the next 12 months out of accumulated other comprehensive income (loss) into earnings is $3.7 million as a decrease to interest income from loans and lease financing. As of September 30, 2023, the maximum length of time over which forecasted transactions are hedged is approximately four years. Free-Standing Derivative Instruments For the derivatives that are not designated as hedges, changes in fair value are reported in current period earnings. The following table summarizes the impact on pretax earnings of derivatives not designated as hedges, as reported on the unaudited interim consolidated statements of income for the three and nine months ended September 30, 2023 and 2022: Net gains (losses) recognized Three Months Ended Nine Months Ended in the consolidated statements September 30, September 30, (dollars in of income line item 2023 2022 2023 2022 Derivatives Not Designated As Hedging Instruments: Interest rate swaps Other noninterest income $ 26 $ — $ (532) $ — Visa derivative Other noninterest income $ (1,350) $ 273 (5,129) (1,084) As of September 30, 2023, the Company carried multiple interest rate swaps with notional amounts totaling $2.8 billion, all of which were related to the Company’s customer swap program, with a positive fair value of $3.1 million and a negative fair value of $1.2 million. The Company received floating rates ranging from 5.82% to 8.33% and paid fixed rates ranging from 2.39% to 5.86%. The swaps mature between October 2023 and June 2040. As of December 31, 2022, the Company carried multiple interest rate swaps with notional amounts totaling $2.8 billion, all of which were related to the Company’s customer swap program, with a positive fair value of $3.2 million and a negative fair value of $42.4 million. The Company received floating rates ranging from 4.62% to 7.12% and paid fixed rates ranging from 2.39% to 6.13%. These swaps resulted in net interest expense of nil during both the three and nine months ended September 30, 2023 and 2022. The Company’s customer swap program is designed by offering customers a variable-rate loan that is swapped to fixed-rate through an interest rate swap. The Company simultaneously executes an offsetting interest rate swap with a swap dealer. Upfront fees on the dealer swap are recorded in other noninterest income and totaled nil and $0.4 million for the three months ended September 30, 2023 and 2022, respectively, and $1.5 million and $1.8 million for the nine months ended September 30, 2023 and 2022, respectively. Visa Class B Restricted Shares In 2016, the Company recorded a $22.7 million net realized gain related to the sale of 274,000 Visa Class B restricted shares. Concurrent with the sale of the Visa Class B restricted shares, the Company entered into a funding swap agreement with the buyer that requires payment to the buyer in the event Visa reduces each member bank’s Class B conversion rate to unrestricted Class A common shares. During 2018 through 2023, Visa funded its litigation escrow account, thereby reducing each member bank’s Class B conversion rate to unrestricted Class A common shares from 1.6483 to the current conversion rate of 1.5875. Under the terms of the funding swap agreement, the Company will make monthly payments to the buyer based on Visa’s Class A stock price and the number of Visa Class B restricted shares that were sold until the date on which the covered litigation is settled. A derivative liability (“Visa derivative”) of $1.2 million and $0.9 million was included in the unaudited interim consolidated balance sheets at September 30, 2023 and December 31, 2022, respectively, to provide for the fair value of this liability. There were no sales of these shares prior to 2016. See “Note 16. Fair Value” for more information. Counterparty Credit Risk By using derivatives, the Company is exposed to counterparty credit risk if counterparties to the derivative contracts do not perform as expected. If a counterparty fails to perform, the Company’s counterparty credit risk is equal to the amount reported as a derivative asset, net of cash or other collateral received, and net of derivatives in a loss position with the same counterparty to the extent master netting arrangements exist. The Company minimizes counterparty credit risk through credit approvals, limits, monitoring procedures, executing master netting arrangements and obtaining collateral, where appropriate. Counterparty credit risk related to derivatives is considered in determining fair value. The Company’s interest rate swap agreements include bilateral collateral agreements with collateral requirements, which begin with exposures in excess of $0.3 million. For each counterparty, the Company reviews the interest rate swap collateral daily. Collateral for customer interest rate swap agreements, calculated as the pledged asset less loan balance, requires valuation of the pledged asset. Counterparty credit risk adjustments of nil were recognized during both the three months ended September 30, 2023 and 2022, and nil and $0.1 million were recognized during the nine months ended September 30, 2023 and 2022, respectively. Credit-Risk Related Contingent Features Certain of the Company’s derivative contracts contain provisions whereby if the Company’s credit rating were to be downgraded by certain major credit rating agencies as a result of a merger or material adverse change in the Company’s financial condition, the counterparty could require an early termination of derivative instruments. The aggregate fair value of all derivative instruments with such credit-risk related contingent features that are in a net liability position was nil at both September 30, 2023 and December 31, 2022, for which the Company posted nil in collateral in the normal course of business. If the Company’s credit rating had been downgraded as of September 30, 2023 and December 31, 2022, the Company may have been required to settle the contracts in an amount equal to their fair value.

Commitments and Contingent Liabilities
Commitments and Contingent Liabilities	12. Commitments and Contingent Liabilities Contingencies On November 2, 2020, a lawsuit was filed in Hawaii Circuit Court by a Bank customer related to the sale of credit facilities that the Bank had previously extended to the customer. The customer asserts claims against the Bank for interference with the customer’s contract and business opportunity, unfair methods of competition and declaratory and injunctive relief. The outcome of this legal proceeding is uncertain at this point. Based on information available to the Company at present, the Company cannot reasonably estimate a range of potential loss, if any, for this action. Accordingly, the Company has not recognized any liability associated with this action. Management disputes any wrongdoing and the case is being vigorously defended. In addition to the litigation noted above, various legal proceedings are pending or threatened against the Company. After consultation with legal counsel, management does not expect that the aggregate liability, if any, resulting from these proceedings would have a material effect on the Company’s unaudited interim consolidated financial position, results of operations or cash flows. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby and commercial letters of credit which are not reflected in the unaudited interim consolidated financial statements. Unfunded Commitments to Extend Credit A commitment to extend credit is a legally binding agreement to lend funds to a customer, usually at a stated interest rate and for a specified purpose. Commitments are reported net of participations sold to other institutions. Such commitments have fixed expiration dates and generally require a fee. The extension of a commitment gives rise to credit risk. The actual liquidity requirements or credit risk that the Company will experience is expected to be lower than the contractual amount of commitments to extend credit because a significant portion of those commitments are expected to expire without being drawn upon. Certain commitments are subject to loan agreements containing covenants regarding the financial performance of the customer that must be met before the Company is required to fund the commitment. The Company uses the same credit policies in making commitments to extend credit as it does in making loans. In addition, the Company manages the potential credit risk in commitments to extend credit by limiting the total amount of arrangements, both by individual customer and in the aggregate, by monitoring the size and expiration structure of these portfolios and by applying the same credit standards maintained for all of its related credit activities. Commitments to extend credit are reported net of participations sold to other institutions of $65.5 million and $90.5 million at September 30, 2023 and December 31, 2022, respectively. Standby and Commercial Letters of Credit Standby letters of credit are issued on behalf of customers in connection with contracts between the customers and third parties. Under standby letters of credit, the Company assures that the third parties will receive specified funds if customers fail to meet their contractual obligations. The credit risk to the Company arises from its obligation to make payment in the event of a customer’s contractual default. Standby letters of credit are reported net of participations sold to other institutions of $8.2 million and $8.1 million at September 30, 2023 and December 31, 2022, respectively. The Company also had commitments for commercial and similar letters of credit. Commercial letters of credit are issued specifically to facilitate commerce whereby the commitment is typically drawn upon when the underlying transaction between the customer and a third-party is consummated. The maximum amount of potential future payments guaranteed by the Company is limited to the contractual amount of these letters. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held supports those commitments for which collateral is deemed necessary. The commitments outstanding as of September 30, 2023 have maturities ranging from October 2023 to September 2026. Substantially all fees received from the issuance of such commitments are deferred and amortized on a straight-line basis over the term of the commitment. Financial instruments with off-balance sheet risk at September 30, 2023 and December 31, 2022 were as follows: September 30, December 31, (dollars in 2023 2022 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 6,722,595 $ 6,760,395 Standby letters of credit 238,704 244,275 Commercial letters of credit 5,410 7,299 Guarantees The Company sells residential mortgage loans in the secondary market primarily to the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation that may potentially require repurchase under certain conditions. This risk is managed through the Company’s underwriting practices. The Company services loans sold to investors and loans originated by other originators under agreements that may include repurchase remedies if certain servicing requirements are not met. This risk is managed through the Company’s quality assurance and monitoring procedures. Management does not anticipate any material losses as a result of these transactions. Foreign Exchange Contracts The Company has forward foreign exchange contracts that represent commitments to purchase or sell foreign currencies at a future date at a specified price. The Company’s utilization of forward foreign exchange contracts is subject to the primary underlying risk of movements in foreign currency exchange rates and to additional counterparty risk should its counterparties fail to meet the terms of their contracts. Forward foreign exchange contracts are utilized to mitigate the Company’s risk to satisfy customer demand for foreign currencies and are not used for trading purposes. See “Note 11. Derivative Financial Instruments” for more information. Reorganization Transactions On April 1, 2016, a series of reorganization transactions were undertaken to facilitate FHI’s initial public offering. In connection with the reorganization transactions, FHI distributed its interest in BancWest Holding Inc. (“BWHI”), including Bank of the West (“BOW”) to BNP Paribas (“BNPP”) so that BWHI was held directly by BNPP. As a result of the reorganization transactions that occurred on April 1, 2016, various tax or other contingent liabilities could arise related to the business of BOW, or related to the Company’s operations prior to the restructuring when it was known as BancWest Corporation, including its then wholly owned subsidiary, BOW. The Company is not able to determine the ultimate outcome or estimate the amounts of these contingent liabilities, if any, at this time.

The guidance explicitly excludes net interest income from financial assets and liabilities as well as other noninterest income from loans, leases, investment securities, derivative financial instruments and bank-owned life insurance. For the three and nine months ended September 30, 2023 and 2022, substantially all of the Company’s revenues under the scope of Topic 606 were related to performance obligations satisfied at a point in time. The following is a discussion of revenues within the scope of Topic 606. Service Charges on Deposit Accounts Service charges on deposit accounts relate to fees generated from a variety of deposit products and services rendered to customers. Charges include, but are not limited to, overdraft fees, non-sufficient fund fees, dormant fees and monthly service charges. Such fees are recognized concurrent with the event on a daily basis or on a monthly basis depending upon the customer’s cycle date. Credit and Debit Card Fees Credit and debit card fees primarily represent revenues earned from interchange fees, ATM fees and merchant processing fees. Interchange and network revenues are earned on credit and debit card transactions conducted with payment networks. ATM fees are primarily earned as a result of surcharges assessed to non-FHB customers who use an FHB ATM. Merchant processing fees are primarily earned on transactions in which FHB is the acquiring bank. Such fees are generally recognized concurrently with the delivery of services on a daily basis. Trust and Investment Services Fees Trust and investment services fees represent revenue earned by directing, holding and managing customers’ assets. Fees are generally computed based on a percentage of the previous period’s value of assets under management. The transaction price (i.e., percentage of assets under management) is established at the inception of each contract. Trust and investment services fees also include fees collected when the Company acts as agent or personal representative and executes security transactions, performs collection and disbursement of income, and completes investment management and other administrative tasks. Other Fees Other fees primarily include revenues generated from wire transfers, lockboxes, bank issuance of checks and insurance commissions. Such fees are recognized concurrent with the event or on a monthly basis. Contract Balances A contract liability is an entity’s obligation to transfer goods or services to a customer for which the entity has received consideration (or the amount is due) from the customer. The Company received signing bonuses from two vendors in prior years, which are being amortized over the term of the respective contracts. As of September 30, 2023 and December 31, 2022, the Company had contract liabilities of $2.1 million and $2.7 million, respectively, which it expects to recognize over the remaining term of the respective contracts with the vendors. For the three and nine months ended September 30, 2023, the Company’s recognized revenues increased and contract liabilities decreased by approximately $0.2 million and $0.6 million due to the passage of time. For the three and nine months ended September 30, 2022, the Company’s recognized revenues increased and contract liabilities decreased by approximately $0.2 million and $0.7 million, respectively, due to the passage of time. There were no changes in contract liabilities due to changes in transaction price estimates.

Fair Value

Fair Value	9 Months Ended
Fair Value	Sep. 30, 2023
Fair Value
Fair Value	16. Fair Value The Company determines the fair values of its financial instruments based on the requirements established in Accounting Standards Codification Topic 820 (“Topic 820”), Fair Value Measurements Fair Value Hierarchy Topic 820 establishes three levels of fair values based on the markets in which the assets or liabilities are traded and the reliability of the assumptions used to determine fair value. The levels are: ◾ Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. ◾ Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. ◾ Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability (“Company-level data”). Level 3 assets and liabilities include financial instruments whose value is determined using unobservable inputs to pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Topic 820 requires that the Company disclose estimated fair values for certain financial instruments. Financial instruments include such items as investment securities, loans, deposits, interest rate and foreign exchange contracts, swaps and other instruments as defined by the standard. The Company has an organized and established process for determining and reviewing the fair value of financial instruments reported in the Company’s financial statements. The fair value measurements are reviewed to ensure they are reasonable and in line with market experience in similar asset and liability classes. Additionally, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, other customer relationships, and other intangible assets. These nonrecurring fair value adjustments typically involve the application of lower-of-cost-or-fair-value accounting or write-downs of individual assets. Disclosure of fair values is not required for certain items such as lease financing, obligations for pension and other postretirement benefits, premises and equipment, prepaid expenses, deposit liabilities with no defined or contractual maturity, and income tax assets and liabilities. Reasonable comparisons of fair value information with that of other financial institutions cannot necessarily be made because the standard permits many alternative calculation techniques, and numerous assumptions have been used to estimate the Company’s fair values. Valuation Techniques Used in the Fair Value Measurement of Assets and Liabilities Carried at Fair Value For the assets and liabilities measured at fair value on a recurring basis (categorized in the valuation hierarchy table below), the Company applies the following valuation techniques: Available-for-sale securities Available-for-sale debt securities are recorded at fair value on a recurring basis. Fair value measurement is based on quoted prices, including estimates by third-party pricing services, if available. If quoted prices are not available, fair values are measured using proprietary valuation models that utilize market observable parameters from active market makers and inter-dealer brokers whereby securities are valued based upon available market data for securities with similar characteristics. Management reviews the pricing information received from the Company’s third-party pricing service to evaluate the inputs and valuation methodologies used to place securities into the appropriate level of the fair value hierarchy and transfers of securities within the fair value hierarchy are made if necessary. On a monthly basis, management reviews the pricing information received from the third-party pricing service which includes a comparison to non-binding third-party broker quotes, as well as a review of market-related conditions impacting the information provided by the third-party pricing service. Management also identifies investment securities which may have traded in illiquid or inactive markets by identifying instances of a significant decrease in the volume or frequency of trades, relative to historical levels, as well as instances of a significant widening of the bid-ask spread in the brokered markets. As of September 30, 2023 and December 31, 2022, management did not make adjustments to prices provided by the third-party pricing services as a result of illiquid or inactive markets. The Company’s third-party pricing service has also established processes for the Company to submit inquiries regarding quoted prices. Periodically, the Company will challenge the quoted prices provided by the third-party pricing service. The Company’s third-party pricing service will review the inputs to the evaluation in light of the new market data presented by the Company. The Company’s third-party pricing service may then affirm the original quoted price or may update the evaluation on a going forward basis. The Company classifies all available-for-sale securities as Level 2. Derivatives Most of the Company’s derivatives are traded in over-the-counter markets where quoted market prices are not readily available. For those derivatives, the Company measures fair value on a recurring basis using proprietary valuation models that primarily use market observable inputs, such as yield curves, and option volatilities. The fair value of derivatives includes values associated with counterparty credit risk and the Company’s own credit standing. The Company classifies these derivatives, included in other assets and other liabilities, as Level 2. Concurrent with the sale of the Visa Class B restricted shares, the Company entered into an agreement with the buyer that requires payment to the buyer in the event Visa reduces each member bank’s Class B conversion rate to unrestricted Class A common shares. During 2018 through 2023, Visa funded its litigation escrow account, thereby reducing each member bank’s Class B conversion rate to unrestricted Class A common shares from 1.6483 to the current conversion rate of 1.5875. The Visa derivative of $1.2 million and $0.9 million was included in the unaudited interim consolidated balance sheets at September 30, 2023 and December 31, 2022, respectively, to provide for the fair value of this liability. The potential liability related to this funding swap agreement was determined based on management’s estimate of the timing and the amount of Visa’s litigation settlement and the resulting payments due to the counterparty under the terms of the contract. As such, the funding swap agreement is classified as Level 3 in the fair value hierarchy. The significant unobservable inputs used in the fair value measurement of the Company’s funding swap agreement are the potential future changes in the conversion rate, expected term and growth rate of the market price of Visa Class A common shares. Material increases (or decreases) in any of those inputs may result in a significantly higher (or lower) fair value measurement. Assets and Liabilities Recorded at Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022 are summarized below: Fair Value Measurements as of September 30, 2023 Quoted Prices in Significant Active Markets for Other Significant Identical Assets Observable Unobservable (dollars in (Level 1) Inputs (Level 2) Inputs (Level 3) Total Assets U.S. Treasury and government agency debt securities $ — $ 114,159 $ — $ 114,159 Government-sponsored enterprises debt securities — 19,260 — 19,260 Mortgage-backed securities: Residential - Government agency (1) — 52,362 — 52,362 Residential - Government-sponsored enterprises (1) — 1,005,782 — 1,005,782 Commercial - Government agency — 211,897 — 211,897 Commercial - Government-sponsored enterprises — 84,920 — 84,920 Commercial - Non-agency — 21,602 — 21,602 Collateralized mortgage obligations: Government agency — 565,852 — 565,852 Government-sponsored enterprises — 400,748 — 400,748 Collateralized loan obligations — 246,122 — 246,122 Total available-for-sale securities — 2,722,704 — 2,722,704 Other assets (2) 1,287 12,902 — 14,189 Liabilities Other liabilities (3) — (5,880) (1,200) (7,080) Total $ 1,287 $ 2,729,726 $ (1,200) $ 2,729,813 (1) Backed by residential real estate.

(2) Excludes deposit liabilities with no defined or contractual maturity of $17.9 billion as of September 30, 2023 and $19.2 billion as of December 31, 2022. Unfunded loan and lease commitments and letters of credit are not included in the tables above. As of both September 30, 2023 and December 31, 2022, the Company had $7.0 billion of unfunded loan and lease commitments and letters of credit. The Company believes that a reasonable estimate of the fair value of these instruments is the carrying value of deferred fees plus the related reserve for unfunded commitments, which totaled $52.3 million and $48.5 million at September 30, 2023 and December 31, 2022, respectively. No active trading market exists for these instruments, and the estimated fair value does not include value associated with the borrower relationship. The Company does not estimate the fair values of certain unfunded loan and lease commitments that can be canceled by providing notice to the borrower. As Company-level data is incorporated into the fair value measurement, unfunded loan and lease commitments and letters of credit are classified as Level 3. Valuation Techniques Used in the Fair Value Measurement of Assets and Liabilities Carried at the Lower of Cost or Fair Value The Company applies the following valuation techniques to assets measured at the lower of cost or fair value: Mortgage servicing rights MSRs are carried at the lower of cost or fair value and are therefore subject to fair value measurements on a nonrecurring basis. The fair value of MSRs is determined using models which use significant unobservable inputs, such as estimates of prepayment rates, the resultant weighted average lives of the MSRs and the option-adjusted spread levels. Accordingly, the Company classifies MSRs as Level 3. Collateral-dependent loans Collateral-dependent loans are those for which repayment is expected to be provided substantially through the operation or sale of the collateral. Other real estate owned The Company values these properties at fair value at the time the Company acquires them, which establishes their new cost basis. After acquisition, the Company carries such properties at the lower of cost or fair value less estimated selling costs on a nonrecurring basis. Fair value is measured on a nonrecurring basis using collateral values as a practical expedient. The fair values of collateral for other real estate owned are primarily based on real estate appraisal reports prepared by third-party appraisers less disposition costs, and are classified as Level 3. Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis The Company may be required to record certain assets at fair value on a nonrecurring basis in accordance with GAAP. These assets are subject to fair value adjustments that result from the application of lower of cost or fair value accounting or write-downs of individual assets to fair value. There were no assets with nonrecurring fair value adjustments held as of September 30, 2023 and December 31, 2022. Additionally, there were no nonrecurring fair value adjustments for both the three and nine months ended September 30, 2023 and 2022.

Reportable Operating Segments

Reportable Operating Segments	9 Months Ended
Reportable Operating Segments	Sep. 30, 2023
Reportable Operating Segments
Reportable Operating Segments	17. Reportable Operating Segments The Company’s operations are organized into three business segments – Retail Banking, Commercial Banking, and Treasury and Other. These segments reflect how discrete financial information is currently evaluated by the chief operating decision maker and how performance is assessed and resources allocated. The Company’s internal management process measures the performance of these business segments. This process, which is not necessarily comparable with similar information for 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. 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. The Company allocates the provision for credit losses from the Treasury and Other business segment (which is comprised of many of the Company’s support units) to the Retail and Commercial business segments. These allocations are based on direct costs incurred by the Retail and Commercial business segments. Noninterest income and expense includes allocations from support units to the business segments. These allocations are based on actual usage where practicably calculated or by management’s estimate of such usage. Income tax expense is allocated to each business segment based on the consolidated effective income tax rate for the period shown. Business Segments Retail Banking Retail Banking offers a broad range of financial products and services to consumers and small businesses. Loan and lease products offered include residential and commercial mortgage loans, home equity lines of credit and loans, automobile loans and leases, secured and unsecured lines of credit, installment loans and small business loans and leases. Deposit products offered include checking, savings, and time deposit accounts. Retail Banking also offers wealth management services. Products and services from Retail Banking are delivered to customers through 50 banking locations throughout the State of Hawaii, Guam and Saipan. Commercial Banking Commercial Banking offers products that include corporate banking related products, commercial real estate loans, commercial lease financing, secured and unsecured lines of credit, automobile loans and auto dealer financing, business deposit products and credit cards. Commercial lending and deposit products are offered primarily to middle-market and large companies locally, nationally and internationally. Treasury and Other Treasury consists of corporate asset and liability management activities including interest rate risk management. The segment’s assets and liabilities (and related interest income and expense) consist of interest-bearing deposits, investment securities, federal funds sold and purchased, government deposits, short- and long-term borrowings and bank-owned properties. The primary sources of noninterest income are from bank-owned life insurance, net gains from the sale of investment securities, foreign exchange income related to customer-driven cross-border wires for business and personal reasons and management of bank-owned properties. 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, Credit and Risk Management, Human Resources, Finance, Administration, Marketing, 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 accompanying unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s 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. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair presentation of the interim period consolidated financial information, have been made. Results of operations for interim periods are not necessarily indicative of results to be expected for the entire year. Intercompany account balances and transactions have been eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events, actual results may differ from these estimates.
Loan Modifications to Borrowers Experiencing Financial Difficulty	Loan Modifications to Borrowers Experiencing Financial Difficulty Loan modifications are assessed by the Company to determine: (1) whether the borrower is experiencing financial difficulty and (2) whether the Company granted the borrower a modification or combination of modifications in the form of one or more of the following modification types: principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay and/or a term extension. If both criteria are met, then the loan modification is subject to additional evaluation for credit losses and enhanced disclosure requirements. Generally, a non-accrual loan that has been modified with a borrower experiencing financial difficulty remains on non-accrual status for at least six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment terms is uncertain, the loan remains on non-accrual status.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses for loans and leases (the “ACL”) is a valuation account that is deducted from the amortized cost basis of loans and leases to present the net amount expected to be collected from loans and leases. Loans and leases are charged-off against the ACL when management believes the loan or lease balance is deemed uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The Company’s ACL and the reserve for unfunded commitments under the Current Expected Credit Losses (“CECL”) approach consist of quantitative and qualitative estimates. The Company’s methodology leverages two quantitative models: a one-variable forward-looking macroeconomic model that estimates the impact of management’s economic outlook and a transition probability matrix that estimates expected losses over the long run. The quantitative estimation is overlaid with qualitative adjustments to account for current conditions and forward-looking factors not captured in the quantitative model. Qualitative adjustments that are considered include adjustments for regulatory determinants, model limitations, model maturity, and other current or anticipated events that are not captured in the Company’s historical loss experience. The Company generally evaluates loans and leases on a collective or pool basis when similar risk characteristics exist. However, loans and leases that do not share similar risk characteristics are evaluated on an individual basis. Such loans and leases evaluated individually are excluded from the collective evaluation. Individually assessed loans are measured for estimated credit loss (“ECL”) based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral, less estimated selling costs, if the loan is collateral-dependent. Management reviews relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts about the future. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency levels, or term as well as for changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. The Company utilizes a Probability of Default (“PD”)/Loss Given Default (“LGD”) framework to estimate the ACL and the reserve for unfunded commitments. The PD represents the percentage expectation to default, measured by assessing loans and leases that migrate to default status (i.e., nonaccrual status, 90 days or more past due, partial or full charge-offs or bankruptcy). LGD is defined as the percentage of the exposure at default (“EAD”) lost at the time of default, net of any recoveries, and will be unique to each of the collateral types securing the Company’s loans. PD and LGD’s are based on past experience of the Company. The ECL on loans and leases is calculated by taking the product of the credit exposure, lifetime default probability (“LDP”) and the LGD. The ECL model is applied to current credit exposures at the account level, using assumptions calibrated at the portfolio segment level using internal historical loan and lease level data. The Company estimates the default risk of a credit exposure over the remaining life of each account using a transition probability matrix approach which captures both the average rate of up/down-grade and default transitions, as well as withdrawal rates which capture the historical rate of exposure decline due to loan and lease amortization and prepayment. To apply the transition matrices, each credit exposure’s remaining life is split into two time segments. The first time segment is for the reasonable and supportable forecast period over which the transition matrices which are applied have been adjusted to incorporate current and forecasted conditions over that period. Management has determined that using a one-year time horizon for the reasonable and supportable forecast period for all classes of loans and leases is a reasonable forecast horizon given the difficulty in predicting future economic conditions with a high degree of certainty. The second time segment is the reversion period from the end of the reasonable and supportable forecast period to the maturity of the exposure, over which long-run average transition matrices are applied. Management elected to use an immediate reversion to the mean approach. Lifetime loss rates are applied against the amortized cost basis of loans and leases and unfunded commitments to estimate the ACL and the reserve for unfunded commitments, respectively. On at least a quarterly basis, management convenes the Bank’s forecasting team which is responsible for reviewing the economic forecast model inputs and outputs and approving the resulting economic adjustment. The model uses a one-variable econometric model to produce factors that modify the long-run default rate assumptions used in the CECL model. These factors are applied to calculate the economic adjustment over the Reasonable and Supportable Forecast Period. At the meeting, management is presented with the economic forecast model input and output as well as the resulting economic adjustment. Depending on the current economic conditions, a range of inputs and outputs may be presented, in which case, using judgment, management will select an input and output. The economic forecast framework also allows management to use judgment in selecting the economic model input in cases where management’s outlook diverges from the official forecasts, and to apply qualitative dollar overlays to account for other economic related conditions not captured in the economic forecast model but are expected to potentially impact losses. The team also reviews other relevant economic variables and economic factors at the time of the meeting that could potentially impact future losses. These materials are presented to the economic forecasting team as they are economic in nature. If determined to be relevant and needing to be considered in the ACL estimate, these risks will be included in the ACL estimate through a qualitative dollar overlay that is determined using either quantitative analysis or qualitative judgment, or a mix of both. These other factors could include inflation indicators, personal income, or visitor arrivals, for example. At present, the Company has identified three portfolio segments in estimating the ACL: commercial, residential real estate and consumer lending. The Company’s commercial portfolio segment is comprised of four distinct classes: commercial and industrial loans, commercial real estate loans, construction loans and lease financing. The key risk drivers related to this portfolio segment include risk rating, collateral type, and remaining maturity. The Company’s residential real estate portfolio segment is comprised of two distinct classes: residential real estate loans and home equity lines of credit. Specific risk characteristics related to this portfolio include the value of the underlying collateral, credit score and remaining maturity. Finally, the Company’s consumer portfolio segment is not further segmented, but consists primarily of automobile loans, credit cards and other installment loans. Automobile loans constitute the majority of this segment and are monitored using credit scores, collateral values and remaining maturity. The remainder of the consumer portfolio is predominantly unsecured. Regarding accrued interest receivable, the Company made accounting policy elections to (1) not measure an ACL on accrued interest receivable, (2) write-off accrued interest receivable by reversing interest income and (3) present accrued interest receivable separately from the related financial asset on the balance sheet. Furthermore, regarding collateral-dependent financial assets, the Company elected the practical expedient to use the fair value of collateral at the reporting date when recording the net carrying amount of the asset and determining the ACL for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Company’s assessment as of the reporting date.
