At December 31, 2020, pledged securities totaled $2.4 billion, of which $2.3 billion was pledged to secure public deposits and $186.1 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, 2021 or December 31, 2020. 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 230 and 50 individual securities in each category have been in a continuous loss position as of September 30, 2021 and December 31, 2020, respectively. The unrealized losses on 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 securities in an unrealized loss position as of September 30, 2021 and December 31, 2020, 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, 2021 and December 31, 2020, the Company did not expect any credit losses in its debt securities and no credit losses were recognized on securities during the three and nine months ended September 30, 2021 and for the year ended December 31, 2020. As of September 30, 2021 and December 31, 2020, the Company’s available-for-sale investment securities were comprised entirely of debt, mortgage-backed securities and collateralized mortgage obligations 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. The Company’s available-for-sale investment 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. Thus, the Company has not recorded an allowance for credit losses for its available-for-sale debt securities as of September 30, 2021 and December 31, 2020. The Company holds approximately 120,000 Visa Class B restricted shares as of both September 30, 2021 and December 31, 2020. These shares continued to be carried at $0 cost basis as of both September 30, 2021 and December 31, 2020.

As of December 31, 2020, residential real estate loans totaling $2.9 billion were pledged to collateralize the Company’s borrowing capacity at the FHLB, and consumer, commercial and industrial, commercial real estate and residential mortgage loans totaling $1.9 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 $4.4 million and $2.3 million as of September 30, 2021 and December 31, 2020, 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	Sep. 30, 2021
Allowance for Credit Losses
Allowance for Credit Losses	4. Allowance for Credit Losses The Company maintains the allowance for credit losses for loans and leases (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. The Company also maintains an estimated reserve for unfunded commitments on the unaudited interim consolidated balance sheets. The reserve for unfunded commitments is reduced in the period in which the off-balance sheet financial instruments expire, loan funding occurs, or is otherwise settled. In response to the COVID-19 pandemic, on March 27, 2020, the CARES Act was signed into law. The CARES Act creates a forbearance program for federally backed mortgage loans, protects borrowers from negative credit reporting due to loan accommodations related to the National Emergency, and provides financial institutions the option to temporarily suspend certain requirements under GAAP related to troubled debt restructurings (“TDRs”) for a limited period of time to account for the effects of COVID-19. Financial institutions accounting for eligible loans under the CARES Act are not required to report such loans as TDRs in accordance with GAAP. In addition, Interagency Statements were issued on March 22, 2020 and April 7, 2020 to encourage financial institutions to work prudently with borrowers and to describe the agencies’ interpretation of how current accounting rules under GAAP apply to certain COVID-19 related modifications. The agencies confirmed with the FASB that short-term modifications (e.g., six months or less) for payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant and made on a good faith basis in response to borrowers impacted by COVID-19 who were current prior to any relief are not TDRs under GAAP. The agencies also confirmed that these short-term modifications should not be reported as being on nonaccrual status and should not be considered past due during the period of the deferral. The Company has adopted the provisions of both the CARES Act and Interagency Statements. The Company is first applying the CARES Act guidance in determining if certain loan modifications are not required to be reported as TDRs. If the loan modification does not qualify under the CARES Act, then the Interagency Statement guidance is applied. On December 27, 2020, the Consolidated Appropriations Act – 2021 (the “CAA”) was signed into law, which extends the temporary relief from the accounting and disclosure requirements for TDRs. To qualify for TDR accounting and disclosure relief under the CARES Act, as amended by the CAA, the applicable loan must not have been more than 30 days past due as of December 31, 2019, and the modification must be executed during the period beginning on March 1, 2020, and ending on the earlier of January 1, 2022, or the date that is 60 days after the termination date of the national emergency declared by the President on March 13, 2020, under the National Emergencies Act related to the outbreak of COVID-19. The interim consolidated financial information below reflects the application of this guidance.

procedures on an ongoing basis. 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.

Mortgage Servicing Rights
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 $1.8 billion and $2.2 billion as of September 30, 2021 and December 31, 2020, respectively. Servicing fees include contractually specified fees, late charges, and ancillary fees, and were $1.1 million and $1.4 million for the three months ended September 30, 2021 and 2020, respectively, and $3.7 million and $4.4 million for the nine months ended September 30, 2021 and 2020, respectively. Amortization of mortgage servicing rights (“MSRs”) was $1.0 million and $1.4 million for the three months ended September 30, 2021 and 2020, respectively, and $2.8 million and $4.7 million for the nine months ended September 30, 2021 and 2020, respectively. The estimated future amortization expenses for MSRs over the next five years are as follows: Estimated (dollars in thousands) Amortization Under one year $ 1,860 One to two years 1,434 Two to three years 1,142 Three to four years 926 Four to five years 763 The details of the Company’s MSRs are presented below: September 30, December 31, (dollars in thousands) 2021 2020 Gross carrying amount $ 69,062 $ 67,856 Less: accumulated amortization 59,955 57,125 Net carrying value $ 9,107 $ 10,731 The following table presents changes in amortized MSRs for the three and nine months ended September 30, 2021 and 2020: Three Months Ended September 30, Nine Months Ended September 30, (dollars in thousands) 2021 2020 2021 2020 Balance at beginning of period $ 10,007 $ 11,595 $ 10,731 $ 12,668 Originations 101 729 1,206 2,935 Amortization (1,001) (1,402) (2,830) (4,681) Balance at end of period $ 9,107 $ 10,922 $ 9,107 $ 10,922 Fair value of amortized MSRs at beginning of period $ 13,480 $ 15,159 $ 14,029 $ 20,329 Fair value of amortized MSRs at end of period $ 12,080 $ 14,282 $ 12,080 $ 14,282 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, 2021 and 2020. The quantitative assumptions used in determining the lower of cost or fair value of the Company’s MSRs as of September 30, 2021 and December 31, 2020 were as follows: September 30, 2021 December 31, 2020 Weighted Weighted Range Average Range Average Conditional prepayment rate 15.12 % - 25.14 % 16.13 % 11.86 % - 26.52 % 16.90 % Life in years (of the MSR) 1.95 - 5.02 4.70 1.83 - 6.68 4.45 Weighted-average coupon rate 3.60 % - 6.65 % 3.73 % 3.24 % - 6.98 % 3.84 % Discount rate 10.00 % - 10.01 % 10.00 % 10.00 % - 10.00 % 10.00 % The sensitivities surrounding MSRs are expected to have an immaterial impact on fair value.

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 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, 2021 and December 31, 2020 were as follows: (dollars in thousands) September 30, 2021 December 31, 2020 Public deposits $ 3,377,544 $ 2,251,508 Federal Home Loan Bank 2,510,228 2,917,317 Federal Reserve Bank 1,851,526 1,919,744 ACH transactions 114,246 111,347 Interest rate swaps 51,987 56,004 Total $ 7,905,531 $ 7,255,920 As the Company did not enter into reverse repurchase agreements or repurchase agreements, no collateral was accepted or pledged as of September 30, 2021 and December 31, 2020. 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, 2021 and December 31, 2020: First Hawaiian Minimum Well- First Hawaiian, Inc. Bank Capital Capitalized (dollars in thousands) Amount Ratio Amount Ratio Ratio (1) Ratio (1) September 30, 2021: Common equity tier 1 capital to risk-weighted assets $ 1,777,705 12.63 % $ 1,764,464 12.53 % 4.50 % 6.50 % Tier 1 capital to risk-weighted assets 1,777,705 12.63 % 1,764,464 12.53 % 6.00 % 8.00 % Total capital to risk-weighted assets 1,953,878 13.88 % 1,940,638 13.79 % 8.00 % 10.00 % Tier 1 capital to average assets (leverage ratio) 1,777,705 7.39 % 1,764,464 7.34 % 4.00 % 5.00 % December 31, 2020: Common equity tier 1 capital to risk-weighted assets $ 1,717,008 12.47 % $ 1,699,485 12.34 % 4.50 % 6.50 % Tier 1 capital to risk-weighted assets 1,717,008 12.47 % 1,699,485 12.34 % 6.00 % 8.00 % Total capital to risk-weighted assets 1,889,958 13.73 % 1,872,427 13.60 % 8.00 % 10.00 % Tier 1 capital to average assets (leverage ratio) 1,717,008 8.00 % 1,699,485 7.92 % 4.00 % 5.00 % (1) As defined by the regulations issued by the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, and Federal Deposit Insurance Corporation (“FDIC”). 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, 2021, 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, 2021, 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 that are designated as a fair value 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 notional amounts and fair values of derivatives held by the Company as of September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 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 $ 22,066 $ — $ (852) $ 22,451 $ — $ (1,276) Derivatives not designated as hedging instruments: Interest rate swaps 2,962,557 68,046 — 3,002,333 129,888 — Visa derivative 102,430 — (852) 92,647 — (4,554) Interest rate caps and floors 148,800 4 (4) 148,800 7 (7) Foreign exchange contracts 992 — — 326 — — (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, 2021, the amount of initial margin cash collateral received by the Company was $1.7 million. As of December 31, 2020, the amount of initial margin cash collateral posted by the Company was $4.8 million. As of September 30, 2021 and December 31, 2020, the variation margin was $68.0 million and $129.9 million, respectively. As of September 30, 2021, the Company pledged $30.5 million in financial instruments and $21.5 million in cash as collateral for interest rate swaps. As of December 31, 2020, the Company pledged $30.8 million in financial instruments and $25.2 million in cash as collateral for interest rate swaps. As of September 30, 2021 and December 31, 2020, 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. 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, 2021 and December 31, 2020, the Company carried one interest rate swap with a notional amount of $22.1 million and $22.5 million, respectively. As of September 30, 2021 and December 31, 2020, the interest rate swap was categorized as a fair value hedge for a commercial and industrial loan with a negative fair value of $0.9 million and $1.3 million, respectively. The Company received a USD Prime floating rate and paid a fixed rate of 2.90% . The swap matures in 2023. 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, 2021 and 2020: Gains (losses) recognized in Three Months Ended Nine Months Ended the consolidated statements September 30, September 30, (dollars in of income line item 2021 2020 2021 2020 Gains (losses) on fair value hedging relationships recognized in interest income (1) : Recognized on interest rate swap Loans and lease financing $ 111 $ 156 $ 425 $ (742) Recognized on hedged item Loans and lease financing (126) (326) (512) 615 As of September 30, 2021 and December 31, 2020, 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, 2021 December 31, 2020 September 30, 2021 December 31, 2020 Line item in the consolidated balance sheets in which the hedged item is included Loans and leases $ 23,290 $ 24,355 $ 975 $ 1,487 Free-Standing Derivative Instruments For the derivatives that are not designated as hedges, changes in fair value are reported in current period earnings.

The Company received floating rates ranging from 0.00% to 3.41% and paid fixed rates ranging from 2.02% to 6.19%. The swaps mature between October 2021 and June 2040. As of December 31, 2020, the Company carried multiple interest rate swaps with notional amounts totaling $3.0 billion, all of which were related to the Company’s customer swap program, with a positive fair value of $129.9 million and a negative fair value of nil. The Company received floating rates ranging from 0.15% to 3.16% and paid fixed rates ranging from 2.02% to 5.78%. These swaps resulted in net interest expense of nil during both the three and nine months ended September 30, 2021 and 2020. 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 $0.3 million and $0.5 million for the three months ended September 30, 2021 and 2020, respectively, and $2.0 million and $7.0 million for the nine months ended September 30, 2021 and 2020, 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 both 2018 and 2019, 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 1.6228. 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 $0.9 million and $4.6 million was included in the unaudited interim consolidated balance sheets at September 30, 2021 and December 31, 2020, 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 and $0.1 million were recognized during the three months ended September 30, 2021 and 2020, respectively, and $0.2 million were recognized during both the nine months ended September 30, 2021 and 2020. Credit-Risk Related Contingent Features Some of our 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 in a net liability position. The aggregate fair value of all derivative instruments with such credit-risk related contingent features that are in a net liability position was $23.8 million and $19.8 million at September 30, 2021 and December 31, 2020, respectively, for which we posted $23.2 million and $20.4 million, respectively, in collateral in the normal course of business. If the Company’s credit rating had been downgraded as of September 30, 2021 and December 31, 2020, we 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 July 2021, a lawsuit was filed by a Bank vendor alleging breach of contract by FHB, relating to services provided to the Bank by the vendor. During the three and nine months ended September 30, 2021, the Company recorded an expense of $2.1 million related to the lawsuit. 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 $101.1 million and $93.1 million at September 30, 2021 and December 31, 2020, 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 $10.8 million and $11.0 million at September 30, 2021 and December 31, 2020, 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, 2021 have maturities ranging from October 2021 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, 2021 and December 31, 2020 were as follows: September 30, December 31, (dollars in 2021 2020 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 6,513,489 $ 5,934,535 Standby letters of credit 175,584 185,108 Commercial letters of credit 5,971 3,834 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.

Revenue from Contracts with Customers	13. Revenue from Contracts with Customers Revenue Recognition In accordance with Topic 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Disaggregation of Revenue In the second quarter of 2021, the Company made changes to the internal measurement of segment operating profits for the purpose of evaluating segment performance and resource allocation. The Company has restated the selected financial information for the three and nine months ended September 30, 2020 in order to conform with the current presentation. See “Note 17. Reportable Operating Segments” contained in our unaudited interim consolidated financial statements for further information. The following table summarizes the Company’s revenues, which includes net interest income on financial instruments and noninterest income, disaggregated by type of service and business segments for the periods indicated: Three Months Ended September 30, 2021 Treasury Retail Commercial and (dollars in Banking Banking Other Total Net interest income (1) $ 97,547 $ 41,218 $ (6,172) $ 132,593 Service charges on deposit accounts 6,151 335 503 6,989 Credit and debit card fees — 14,105 1,302 15,407 Other service charges and fees 6,218 1,036 417 7,671 Trust and investment services income 8,625 — — 8,625 Other 64 1,387 233 1,684 Not in scope of Topic 606 (1) 1,640 1,454 6,634 9,728 Total noninterest income 22,698 18,317 9,089 50,104 Total revenue $ 120,245 $ 59,535 $ 2,917 $ 182,697 Nine Months Ended September 30, 2021 Treasury Retail Commercial and (dollars in thousands) Banking Banking Other Total Net interest income (1) $ 289,107 $ 119,718 $ (15,593) $ 393,232 Service charges on deposit accounts 18,025 899 1,415 20,339 Credit and debit card fees — 41,322 4,170 45,492 Other service charges and fees 17,765 3,101 1,151 22,017 Trust and investment services income 25,824 — — 25,824 Other 292 3,506 936 4,734 Not in scope of Topic 606 (1) 6,862 5,058 13,017 24,937 Total noninterest income 68,768 53,886 20,689 143,343 Total revenue $ 357,875 $ 173,604 $ 5,096 $ 536,575 (1) Most of the Company’s revenue is not within the scope of ASU No. 2014-09, Revenue from Contracts with Customers .

The guidance explicitly excludes net interest income from financial assets and liabilities as well as other noninterest income from loans, leases, investment securities and derivative financial instruments. For the three and nine months ended September 30, 2021 and 2020, 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. In prior years, the Company received signing bonuses from two vendors which are being amortized over the term of the respective contracts. As of September 30, 2021 and December 31, 2020, the Company had contract liabilities of $0.4 million and $1.0 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, 2021, the Company’s recognized revenues increased and contract liabilities decreased by approximately $0.2 million and $0.6 million, respectively, due to the passage of time. For the three and nine months ended September 30, 2020, the Company’s recognized revenues increased and contract liabilities decreased by approximately $0.2 million and $0.6 million, respectively, due to the passage of time. There were no changes in contract liabilities due to changes in transaction price estimates. A contract asset is the right to consideration for transferred goods or services when the amount is conditioned on something other than the passage of time. As of September 30, 2021 and December 31, 2020, there were no material receivables from contracts with customers or contract assets recorded on the Company’s consolidated balance sheets. Other Except for the contract liabilities noted above, the Company did not have any significant performance obligations as of September 30, 2021 and December 31, 2020. The Company also did not have any material contract acquisition costs or use any significant judgments or estimates in recognizing revenue for financial reporting purposes.

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, 2021 and December 31, 2020, 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 both 2018 and 2019, 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 1.6228. The Visa derivative of $0.9 million and $4.6 million was included in the unaudited interim consolidated balance sheets at September 30, 2021 and December 31, 2020, 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, 2021 and December 31, 2020 are summarized below: Fair Value Measurements as of September 30, 2021 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 $ — $ 187,861 $ — $ 187,861 Mortgage-backed securities: Residential - Government agency (1) — 98,134 — 98,134 Residential - Government-sponsored enterprises (1) — 1,458,878 — 1,458,878 Commercial - Government agency — 448,594 — 448,594 Commercial - Government-sponsored enterprises — 1,301,249 — 1,301,249 Collateralized mortgage obligations: Government agency — 2,059,864 — 2,059,864 Government-sponsored enterprises — 2,399,147 — 2,399,147 Total available-for-sale securities — 7,953,727 — 7,953,727 Other assets (2) 7,327 68,050 — 75,377 Liabilities Other liabilities (3) — (856) (852) (1,708) Total $ 7,327 $ 8,020,921 $ (852) $ 8,027,396 (1) Backed by residential real estate.

(2) Excludes deposit liabilities with no defined or contractual maturity of $20.2 billion as of September 30, 2021 and $16.9 billion as of December 31, 2020. (3) Excludes capital lease obligations of $10 thousand as of December 31, 2020. Unfunded loan and lease commitments and letters of credit are not included in the tables above. As of September 30, 2021 and December 31, 2020, the Company had $6.7 billion and $6.1 billion, respectively, 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 $46.6 million and $42.3 million at September 30, 2021 and December 31, 2020, 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. The following table provides the level of valuation inputs used to determine each fair value adjustment and the fair value of the related individual assets or portfolio of assets with fair value adjustments on a nonrecurring basis as of September 30, 2021 and December 31, 2020: (dollars Level 1 Level 2 Level 3 September 30, 2021 Collateral-dependent loans $ — $ — $ — December 31, 2020 Collateral-dependent loans $ — $ — $ 1,840 Total expected credit losses recognized on collateral-dependent loans were nil for both the three months ended September 30, 2021 and 2020, and nil and $0.4 million for the nine months ended September 30, 2021 and 2020, respectively. For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of September 30, 2021 and December 31, 2020, the significant unobservable inputs used in the fair value measurements were as follows: Quantitative Information about Level 3 Fair Value Measurements at September 30, 2021 Significant (dollars in thousands) Fair value Valuation Technique Unobservable Input Range Visa derivative $ (852) Discounted Cash Flow Expected Conversation Rate - 1.6228 (2) 1.5977 - 1.6228 Expected Term - 1 year (3) 0.5 to 1.5 years Growth Rate - 13% (4) 4% - 17% Quantitative Information about Level 3 Fair Value Measurements at December 31, 2020 Significant (dollars in thousands) Fair value Valuation Technique Unobservable Input Range Collateral-dependent loans $ 1,840 Appraisal Value Appraisal Value n/m (1) Visa derivative $ (4,554) Discounted Cash Flow Expected Conversation Rate - 1.6228 (2) 1.5977-1.6228 Expected Term - 1 year (3) 0.5 to 1.5 years Growth Rate - 13% (4) 4% - 17% (1) The fair value of these assets is determined based on appraised values of the collateral or broker opinions, the range of which is not meaningful to disclose. (2) Due to the uncertainty in the movement of the conversion rate, the current conversion rate was utilized in the fair value calculation. (3) The expected term of 1 year was based on the median of 0.5 to 1.5 years. (4) The growth rate of 13% was based on the arithmetic average of analyst price targets.

Reportable Operating Segments

Reportable Operating Segments	9 Months Ended
Reportable Operating Segments	Sep. 30, 2021
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. The CARES Act, enacted on March 27, 2020, established, among other COVID-19 relief programs, a loan program (the “PPP”) for fully guaranteed loans (which may then be forgiven) to small businesses. In the second quarter of 2021, the Company made changes to the internal measurement of segment operating profits for the purpose of evaluating segment performance and resource allocation. The primary reason for the change was to align PPP loan balances within the business segment that directly manages them. Specifically, PPP loan balances previously included as part of the Retail Banking segment have been reclassified to the Commercial Banking segment. The reallocation of select PPP loan balances affected net interest income, net interest income after provision for credit losses, noninterest expense, provision for income taxes, net income and asset balances. The Company has reported its selected financial information using the new PPP loan balance alignments for the three and nine months ended September 30, 2021. The Company has restated the selected financial information for the three and nine months ended September 30, 2020 in order to conform with the current presentation. 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, automobile loans and leases, personal 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 54 banking locations throughout the State of Hawaii, Guam, and Saipan. Commercial Banking Commercial Banking offers products that include corporate banking, commercial real estate loans, commercial lease financing, 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 currency requests from merchants and island visitors 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.
