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 to consumer and commercial customers including loans, deposit products, wealth management, insurance, trust, retirement planning, credit card and merchant processing services. 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, 2017. 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. Reorganization Transactions In connection with FHI’s initial public offering (“IPO”) in August 2016 in which BNP Paribas (“BNPP”) sold approximately 17% of its interest in FHI, BNPP announced its intent to sell a controlling interest in FHI, including FHI’s wholly owned subsidiary FHB, over time, subject to market conditions and other considerations. On April 1, 2016, a series of reorganization transactions (the “Reorganization Transactions”) were undertaken to facilitate the IPO. As part of the Reorganization Transactions, FHI, which was then known as BancWest Corporation (“BancWest”), formed a new bank holding company, BancWest Holding Inc. (“BWHI”), a Delaware corporation and a direct wholly owned subsidiary of BancWest, and contributed 100% of its interest in Bank of the West (“BOW”), as well as other assets and liabilities not related to FHB, to BWHI. Following the contribution of BOW to BWHI, BancWest distributed its interest in BWHI to BNPP. As part of these transactions, BancWest amended its certificate of incorporation to change its name to “First Hawaiian, Inc.”, with First Hawaiian Bank remaining as the only direct wholly owned subsidiary of FHI. On July 1, 2016, in order to comply with the Board of Governors of the Federal Reserve System’s requirement (under Regulation YY) applicable to BNPP that a foreign banking organization with $50 billion or more in U.S. non-branch assets as of June 30, 2015 establish a U.S. intermediate holding company and hold its interest in the substantial majority of its U.S. subsidiaries through the intermediate holding company by July 1, 2016, FHI became an indirect subsidiary of BNP Paribas USA, Inc. (“BNP Paribas USA”), BNPP’s U.S. intermediate holding company. As part of that reorganization, FHI became a direct wholly owned subsidiary of BancWest Corporation (“BWC”), a direct wholly owned subsidiary of BNP Paribas USA. As used herein, “BWC” refers, for all periods beginning April 1, 2016, to BancWest Corporation, a Delaware corporation and indirect wholly owned subsidiary of BNPP. On August 4, 2016, FHI’s common stock began trading on the NASDAQ Global Select Market (“NASDAQ”) under the ticker symbol “FHB”. On August 9, 2016, the IPO of 24,250,000 shares of FHI common stock, which included the full exercise of the underwriters’ option to purchase an additional 3,163,043 shares, at a price to the public of $23.00 per share was completed. On February 17, 2017, a secondary offering of 28,750,000 shares of FHI common stock, which included the full exercise of the underwriters’ option to purchase an additional 3,750,000 shares, at a price to the public of $32.00 per share was completed. On May 10, 2018, a secondary offering of 15,300,000 shares of FHI common stock at a price to the public of $27.75 per share was completed. Concurrently with the secondary offering completed on May 10, 2018, FHI entered into a share repurchase agreement with BWC and completed the repurchase of 2,968,069 shares of FHI common stock at $27.56 per share, the per share price paid by the underwriters to BWC in the concurrent public offering. On June 8, 2018, the underwriters’ exercised their full option to purchase an additional 1,530,000 shares of FHI common stock at $27.56 per share. On August 1, 2018, a secondary offering of 20,000,000 shares of FHI common stock at a price to the public of $27.90 per share was completed. Concurrently with the secondary offering completed on August 1, 2018, FHI entered into a share repurchase agreement with BWC and completed the repurchase of 1,801,801 shares of FHI common stock at $27.75 per share, the per share price paid by the underwriters to BWC in the concurrent public offering. Lastly, on September 10, 2018, in a secondary offering, BWC sold 20,000,000 shares of FHI common stock at a variable price to the public. The per share price paid in the offering to BWC by the underwriters was $28.70. FHI did not receive any of the proceeds from the sales of shares of FHI common stock in the secondary offerings completed on September 10, 2018, August 1, 2018, May 10, 2018 or February 17, 2017 or the IPO on August 9, 2016. As of September 30, 2018, BNPP remained the beneficial owner of approximately 18% of FHI’s outstanding common stock. 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. Correction of an Immaterial Error to the Financial Statements Subsequent to the issuance of the Company’s unaudited interim September 30, 2017 consolidated financial statements, the Company’s management determined that certain expenses related to the Company’s card rewards program were incorrectly offset against credit and debit card fee income and credit card interchange assessment fees were incorrectly classified in card rewards program expense instead of credit and debit card fee income in the consolidated statements of income for the three and nine months ended September 30, 2017. For the three and nine months ended September 30, 2017, income from service charges on deposit accounts was overstated by $0.2 million and $0.5 million, respectively, credit and debit card fee income was understated by $1.3 million and $5.0 million, respectively, occupancy expense was understated by $0.4 million and $1.2 million, respectively, and card rewards program expense was understated by $0.7 million and $3.3 million, respectively. As a result, certain noninterest income and noninterest expense amounts have been restated from the amounts previously reported to correct the classification errors. There was no change to net income or earnings per share as previously reported as a result of these errors. Management has evaluated the materiality of these errors on its prior period financial statements from a quantitative and qualitative perspective, and has concluded that these errors were not material to the prior periods. Accounting Standards Adopted in 2018 In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) . This guidance requires entities to recognize revenues when they transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the provisions of ASU No. 2014-09 on January 1, 2018. The Company adopted the new guidance using the modified retrospective transition approach, in which the guidance would only be applied to existing contracts in effect at January 1, 2018 and new contracts entered into after this date. Most of the Company’s revenue is comprised of net interest income on loans, leases, investment securities and deposits, all of which is explicitly out of scope of the new revenue recognition guidance. Management conducted an assessment of the revenue streams that were potentially affected by the new guidance and reviewed contracts in scope to ensure compliance with the new guidance. These contracts included those related to credit and debit card fees, service charges and fees on deposit accounts, and trust and investment services fees. The adoption of ASU No. 2014-09 did not have a material impact on the Company’s consolidated financial statements. However, additional disclosures required by the standard have been included in “Note 15. Revenue from Contracts with Customers” to the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . This guidance requires entities to report the service cost component of net periodic benefit cost in the same line item as other compensation costs arising from services rendered by pertinent employees during the reporting period. The other components of net periodic benefit costs are to be presented in the income statement separately from the service cost component. The Company adopted the provisions of ASU No. 2017-07 on January 1, 2018 and applied the guidance retrospectively to all periods for which a statement of income is presented. The Company continues to record the service cost component of net periodic benefit cost in salaries and employee benefits expense; however, all other components of net periodic benefit cost are now recorded in other noninterest expense. The Company elected to use the practical expedient which permits entities to estimate amounts for comparative periods using the information previously disclosed in the Company’s pension and other postretirement benefit plan disclosure as such amounts are not material. The adoption of ASU No. 2017-07 did not have a material impact on the Company’s consolidated financial statements. See “Note 17. Benefit Plans” for required disclosures. In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718), Scope of Modification Accounting. This guidance applies to entities that change the terms or conditions of a share-based payment award. This guidance clarifies when an entity should account for a change as a modification. Modification accounting will be required only if the fair value, the vesting conditions or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The Company adopted the provisions of ASU No. 2017-09 on January 1, 2018. The adoption of ASU No. 2017-09 did not have a material impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This guidance provided entities with an option to reclassify tax effects that were stranded in accumulated other comprehensive income, pursuant to the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), to retained earnings. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. However, this guidance may be early adopted in any interim or annual period for which financial statements have not yet been issued and applied either in the period of adoption or retrospectively to each period in which the effect of the change in the corporate tax rate in the Tax Act is recognized. The Company elected to early adopt the provisions of ASU No. 2018-02 on January 1, 2018 and reflected the reclassification related to the Tax Act in the period of adoption. The amount of the reclassification reflected the impact of the Tax Act that was signed into law on December 22, 2017 which reduced the corporate tax rate from 35% to 21%. The result of the early adoption of ASU No. 2018-02 was to reclassify a credit balance of $20.1 million from accumulated other comprehensive loss to retained earnings as of January 1, 2018. The Company utilizes a security-by-security approach to releasing income tax effects from accumulated other comprehensive loss. The adoption of ASU No. 2018-02 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 February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance provides that lessees will be required to recognize the following for all operating leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee's obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements to Topic 842, Leases . Specifically, entities may elect not to recast comparative periods presented when transitioning to Topic 842 and lessors may elect not to separate lease and nonlease components when certain conditions are met. The Company expects to elect the practical expedient to not recast comparative periods upon the adoption of ASU No. 2016-02 on January 1, 2019. As lessee, the Company has lease agreements for branch premises, ATM locations and information technology equipment that are currently considered operating leases, and therefore, are not recognized on the Company’s consolidated balance sheets. The Company has formed a working group comprised of teams from different disciplines, including finance, bank properties and information technology. The Company has also engaged a software vendor to assist in complying with the new lease accounting requirements. The FASB has made available several practical expedients to assist entities with adoption. In addition to the transition practical expedient noted above, the Company expects to elect the package of practical expedients which among other things, would require no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for existing leases. Additionally, the Company does not plan to elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of right-of-use assets. While the Company has not yet quantified the impact to the consolidated balance sheet upon the adoption of this new guidance, the Company expects to report increased assets and liabilities as a result of recognizing right-of-use assets and lease liabilities related to the Company’s operating lease agreements noted above. However, the Company does not expect the adoption of ASU No. 2016-02 will have a material impact on its consolidated statements of income as the majority of its leases will remain operating in nature. As such, the expense recognition will be similar to previously required straight-line expense treatment. In conjunction with the Company’s adoption of ASU No. 2016-02, management is also assessing internal controls to ensure that complete, accurate and up-to-date records of all lease agreements are not only available at commencement of a lease, but also throughout the term of the lease agreement. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments . This guidance eliminates the probable recognition threshold for credit losses on financial assets measured at amortized cost. For loans and held-to-maturity debt securities, this update requires a current expected credit loss (“CECL”) approach to determine the allowance for credit losses. CECL requires loss estimates for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. In addition, this guidance modifies the other-than-temporary impairment model for available-for-sale debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for a reversal of credit losses in future periods. This guidance requires entities to record a cumulative effect adjustment to the consolidated balance sheet as of the beginning of the first reporting period in which the guidance is effective. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted. The new guidance will require significant operational changes, particularly in data collection and analysis. The Company has formed a working group comprised of teams from different disciplines, including credit, finance and information technology, to evaluate the requirements of the new standard and the impact it will have on the Company’s current processes. Management has evaluated the Company’s existing credit loss forecasting models to determine their appropriateness for CECL, has performed a data gap analysis, and is developing analytical approaches to determine CECL model inputs. The Company has also engaged a software vendor to assist in implementing a CECL production platform. However, as the impact of adopting the new guidance is expected to be heavily influenced by an assessment of the composition, characteristics, and credit quality of the Company’s loan and investment securities portfolio as well as the economic conditions in effect at the adoption date, management is currently unable to reasonably estimate the impact of adopting the new standard. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . This guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the current two-step goodwill impairment test. This guidance provides that a goodwill impairment test be conducted by comparing the fair value of a reporting unit with its carrying amount. Entities are to recognize an impairment charge for goodwill by the amount by which the carrying amount exceeds the reporting unit’s fair value. Entities will continue to have the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. This guidance shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities . The objectives of the new guidance are to: (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities, and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Historically, the Company has participated in limited activities in fair value and cash flow hedging relationships. As a result, the adoption of ASU No. 2017-12 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This guidance is a part of the FASB’s disclosure framework project to improve disclosure effectiveness. This guidance eliminates certain disclosure requirements for fair value measurements: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, an entity’s policy for the timing of transfers between levels of the fair value hierarchy and an entity’s valuation processes for Level 3 fair value measurements. This guidance also adds new disclosure requirements for public entities: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop recurring and nonrecurring Level 3 fair value measurements, including how the weighted average is calculated. Furthermore, this guidance modifies certain requirements which will involve disclosing: transfers into and out of Level 3 of the fair value hierarchy, purchases and issuances of Level 3 assets and liabilities, and information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2018-13 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . This guidance aligns the accounting for implementation costs related to a hosting arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Common examples of hosting arrangements include software as a service, platform or infrastructure as a service and other similar types of hosting arrangements. While capitalized costs related to internal-use software is generally considered an intangible asset, costs incurred to implement a cloud computing arrangement that is a service contract would typically be characterized in the company’s financial statements in the same manner as other service costs (e.g., prepaid expense). The new guidance provides that an entity would be required to amortize capitalized implementation costs over the term of the hosting arrangement on a straight-line basis unless another systematic and rational basis is more representative of the pattern in which the entity expects to benefit from access to the hosted software. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted in any annual or interim period for which financial statements have not yet been issued or made available for issuance. The Company expects to early adopt the provisions of ASU No. 2018-15 on January 1, 2019 due to the Company’s shift towards utilizing more hosting arrangements that is a service contract. Management is currently evaluating the impact that the adoption of ASU No. 2018-15 will have on the Company’s consolidated financial statements.

Investment Securities	2. Investment Securities As of September 30, 2018 and December 31, 2017, investment securities consisted predominantly of the following investment categories: U.S. Treasury and debt securities – includes U.S. Treasury notes and debt securities issued by government- sponsored enterprises. Mortgage-backed securities – includes securities backed by notes or receivables secured by mortgage assets with cash flows based on actual or scheduled payments. Collateralized mortgage obligations – includes securities backed by a pool of mortgages with cash flows distributed based on certain rules rather than pass through payments. Debt securities issued by states and political subdivisions – includes general obligation bonds issued by state and local governments. As of September 30, 2018 and December 31, 2017, all of the Company’s investment securities were classified as debt securities and available-for-sale. Amortized cost and fair value of securities as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 December 31, 2017 Amortized Unrealized Unrealized Fair Amortized Unrealized Unrealized Fair (dollars in thousands) Cost Gains Losses Value Cost Gains Losses Value U.S. Treasury securities $ 403,425 $ — $ (19,535) $ 383,890 $ 404,376 $ — $ (12,121) $ 392,255 Government-sponsored enterprises debt securities 249,716 — (12,499) 237,217 249,712 — (7,111) 242,601 Government agency mortgage-backed securities 439,773 — (20,480) 419,293 356,858 — (5,468) 351,390 Government-sponsored enterprises mortgage-backed securities 161,975 93 (7,935) 154,133 178,702 169 (4,130) 174,741 Collateralized mortgage obligations: Government agency 2,906,962 — (152,996) 2,753,966 3,367,173 47 (76,746) 3,290,474 Government-sponsored enterprises 657,793 — (30,554) 627,239 779,911 25 (17,218) 762,718 Debt securities issued by states and political subdivisions 20,344 — (781) 19,563 20,543 — (64) 20,479 Total available-for-sale securities $ 4,839,988 $ 93 $ (244,780) $ 4,595,301 $ 5,357,275 $ 241 $ (122,858) $ 5,234,658 Proceeds from both calls and sales of investment securities were nil for both the three and nine months ended September 30, 2018 and 2017. The Company recorded no gross realized gains and no gross realized losses for both the three and nine months ended September 30, 2018 and 2017. Accordingly, no provision for income taxes related to net realized gains on the sale of investment securities was recorded for the three and nine months ended September 30, 2018 and 2017. Gains and losses realized on sales of securities are determined using the specific identification method. Interest income from taxable investment securities was $25.1 million and $24.2 million for the three months ended September 30, 2018 and 2017, respectively, and $81.2 million and $75.7 million for the nine months ended September 30, 2018 and 2017, respectively. Interest income from non-taxable investment securities was $0.1 million and $0.4 million during the three and nine months ended September 30, 2018, respectively. The Company did not own any non-taxable investment securities during the three and nine months ended September 30, 2017. The amortized cost and fair value of debt securities issued by the U.S. Treasury, government-sponsored enterprises and states and political subdivisions as of September 30, 2018, by contractual maturity, are shown below. Mortgage-backed securities and collateralized mortgage obligations 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, 2017, pledged securities totaled $3.0 billion, of which $2.8 billion was pledged to secure public deposits and $229.2 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, 2018 and December 31, 2017. The following table presents the unrealized gross losses and fair values of securities in the available-for-sale portfolio by length of time that the 202 and 196 individual securities in each category have been in a continuous loss position as of September 30, 2018 and December 31, 2017, 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.

Investment securities are evaluated for OTTI on at least a quarterly basis, and more frequently when economic and market conditions warrant such an evaluation, to determine whether the decline in fair value below amortized cost is other than temporary. The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. The decline in value is not related to any issuer- or industry-specific credit event. At September 30, 2018 and December 31, 2017, the Company did not have the intent to sell and determined it was more likely than not that the Company would not be required to sell the securities prior to recovery of the amortized cost basis. As the Company has the intent and ability to hold securities in an unrealized loss position, each security with an unrealized loss position in the above tables has been further assessed to determine if a credit loss exists. If it is probable that the Company will not collect all amounts due according to the contractual terms of an investment security, an OTTI is considered to have occurred. In determining whether a credit loss exists, the Company estimates the present value of future cash flows expected to be collected from the investment security. If the present value of future cash flows is less than the amortized cost basis of the security, an OTTI exists. As of September 30, 2018 and December 31, 2017, the Company did not expect any credit losses in its debt securities and no OTTI was recognized on securities during the three and nine months ended September 30, 2018 and for the year ended December 31, 2017. Visa Class B Restricted Shares In 2008, the Company received 394,000 Visa Class B restricted shares as part of Visa’s initial public offering. Visa Class B restricted shares are not currently convertible to publicly traded Visa Class A common shares, and only transferable in limited circumstances, until the settlement of certain litigation which are indemnified by Visa members, including the Company. As there are existing transfer restrictions and the outcome of the aforementioned litigation is uncertain, these shares were included in the consolidated balance sheets at their historical cost of $0. 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 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. On June 28, 2018, Visa additionally funded its litigation escrow account, thereby reducing each member bank’s Class B conversion rate to unrestricted Class A common shares. Accordingly, on July 5, 2018, Visa announced a decrease in conversion rate from 1.6483 to 1.6298 effective June 28, 2018. In July 2018, the Company made a payment of approximately $0.7 million to the buyer as a result of the reduction in the Visa Class B conversion rate. See “Note 13. Derivative Financial Instruments” for more information. The Company held approximately 120,000 Visa Class B restricted shares as of both September 30, 2018 and December 31, 2017. These shares continued to be carried at $0 cost basis during each of the respective periods.

Loans and Leases As of September 30, 2018 and December 31, 2017, loans and leases were comprised of the following: September 30, December 31, (dollars in thousands) 2018 2017 Commercial and industrial $ 2,969,237 $ 3,135,266 Real estate: Commercial 2,891,753 2,667,597 Construction 612,794 632,911 Residential 4,313,489 4,090,053 Total real estate 7,818,036 7,390,561 Consumer 1,651,877 1,586,476 Lease financing 161,314 165,066 Total loans and leases $ 12,600,464 $ 12,277,369 Outstanding loan balances are reported net of unearned income, including net deferred loan costs of $35.8 million and $31.2 million at September 30, 2018 and December 31, 2017, respectively. As of September 30, 2018, residential real estate loans totaling $2.6 billion were pledged to collateralize the Company’s borrowing capacity at the Federal Home Loan Bank of Des Moines (“FHLB”), and consumer and commercial and industrial loans totaling $969.9 million were pledged to collateralize the borrowing capacity at the Federal Reserve Bank of San Francisco (“FRB”). As of December 31, 2017, residential real estate loans totaling $2.4 billion were pledged to collateralize the Company’s borrowing capacity at the FHLB, and consumer and commercial and industrial loans totaling $914.5 million were pledged to collateralize the borrowing capacity at the FRB. Residential real estate loans collateralized by properties that were in the process of foreclosure totaled $3.5 million and $3.3 million at September 30, 2018 and December 31, 2017, 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 stability of the state or territories, which affects property values, and the financial strength and creditworthiness of the borrowers. At September 30, 2018 and December 31, 2017, remaining loan and lease commitments were comprised of the following: September 30, December 31, (dollars in thousands) 2018 2017 Commercial and industrial $ 2,609,587 $ 2,406,261 Real estate: Commercial 108,911 78,266 Construction 511,666 450,856 Residential 944,619 980,792 Total real estate 1,565,196 1,509,914 Consumer 1,504,323 1,485,588 Total loan and lease commitments $ 5,679,106 $ 5,401,763

Allowance for Loan and Lease Lo

Allowance for Loan and Lease Losses	9 Months Ended

Allowance for Loan and Lease Losses
Allowance for Loan and Lease Losses	4. Allowance for Loan and Lease Losses The Company must maintain an allowance for loan and lease losses (the “Allowance”) that is adequate to absorb estimated probable credit losses associated with its loan and lease portfolio. The Allowance consists of an allocated portion, which covers estimated credit losses for specifically identified loans and pools of loans and leases, and an unallocated portion. Segmentation Management has identified three primary portfolio segments in estimating the Allowance: commercial lending, residential real estate lending and consumer lending. Commercial lending is further segmented into four distinct classes based on characteristics relating to the borrower, transaction, and collateral. These portfolio segments are: commercial and industrial, commercial real estate, construction, and lease financing. Residential real estate is not further segmented, but consists of single-family residential mortgages, real estate secured installment loans and home equity lines of credit. Consumer lending is not further segmented, but consists primarily of automobile loans, credit cards, and other installment loans. Management has developed a methodology for each segment and class taking into consideration portfolio segment-specific and class-specific factors such as product type, loan portfolio characteristics, management information systems, and other risk factors. Specific Allocation Commercial A specific allocation is determined for individually impaired commercial loans. A loan is considered impaired when it is probable that the Company will be unable to collect the full amount of principal and interest according to the contractual terms of the loan agreement. Management identifies material impaired loans based on their size in relation to the Company’s total loan and lease portfolio. Each impaired loan equal to or exceeding a specified threshold requires an analysis to determine the appropriate level of reserve for that specific loan. Impaired loans below the specified threshold are treated as a pool, with specific allocations established based on qualitative factors such as asset quality trends, risk identification, lending policies, portfolio growth, and portfolio concentrations. Residential A specific allocation is determined for residential real estate loans based on delinquency status. In addition, each impaired loan equal to or exceeding a specified threshold requires analysis to determine the appropriate level of reserve for that specific loan, generally based on the value of the underlying collateral less estimated costs to sell. The specific allocation will be zero for impaired loans in which the value of the underlying collateral, less estimated costs to sell, exceeds the unpaid principal balance of the loan. Consumer A specific allocation is determined for the consumer loan portfolio using delinquency-based formula allocations. The Company uses a formula approach in determining the consumer loan specific allocation and recognizes the statistical validity of measuring losses predicated on past due status. Pooled Allocation Commercial Pooled allocation for pass, special mention, substandard, and doubtful grade commercial loans and leases that share common risk characteristics and properties is determined using a historical loss rate analysis and qualitative factor considerations. Loan grade categories are discussed under “Credit Quality”. Residential and Consumer Pooled allocation for non-delinquent consumer and residential real estate loans is determined using a historical loss rate analysis and qualitative factor considerations. Qualitative Adjustments Qualitative adjustments to historical loss rates or other static sources may be necessary since these rates may not be an accurate indicator of losses inherent in the current portfolio. To estimate the level of adjustments, management considers factors including global, national and local economic conditions; levels and trends in problem loans; the effect of credit concentrations; collateral value trends; changes in risk due to changes in lending policies and practices; management expertise; industry and regulatory trends; and volume of loans. Unallocated Allowance The Company’s Allowance incorporates an unallocated portion to cover risk factors and events that may have occurred as of the evaluation date that have not been reflected in the risk measures utilized due to inherent limitations in the precision of the estimation process. These risk factors, in addition to past and current events based on facts at the unaudited interim consolidated balance sheet date and realistic courses of action that management expects to take, are assessed in determining the level of unallocated allowance. The Allowance was comprised of the following for the periods indicated: Three Months Ended September 30, 2018 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Balance at beginning of period $ 35,239 $ 20,507 $ 7,606 $ 557 $ 43,925 $ 31,509 $ 1,258 $ 140,601 Charge-offs (303) — — — (125) (5,700) — (6,128) Recoveries 51 21 — — 442 1,803 — 2,317 Increase (decrease) in Provision (1,551) 286 (1,388) (29) 147 6,381 614 4,460 Balance at end of period $ 33,436 $ 20,814 $ 6,218 $ 528 $ 44,389 $ 33,993 $ 1,872 $ 141,250 Nine Months Ended September 30, 2018 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Balance at beginning of period $ 34,006 $ 18,044 $ 6,817 $ 611 $ 42,852 $ 31,249 $ 3,674 $ 137,253 Charge-offs (778) — — — (159) (18,615) — (19,552) Recoveries 154 175 — — 684 6,106 — 7,119 Increase (decrease) in Provision 54 2,595 (599) (83) 1,012 15,253 (1,802) 16,430 Balance at end of period $ 33,436 $ 20,814 $ 6,218 $ 528 $ 44,389 $ 33,993 $ 1,872 $ 141,250 Three Months Ended September 30, 2017 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Balance at beginning of period $ 33,341 $ 20,011 $ 5,471 $ 857 $ 44,374 $ 27,903 $ 4,926 $ 136,883 Charge-offs (408) — — (1) (293) (6,263) — (6,965) Recoveries 582 336 — — 139 1,852 — 2,909 Increase (decrease) in Provision (1,677) 234 353 (36) 657 5,107 (138) 4,500 Balance at end of period $ 31,838 $ 20,581 $ 5,824 $ 820 $ 44,877 $ 28,599 $ 4,788 $ 137,327 Nine Months Ended September 30, 2017 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Balance at beginning of period $ 33,129 $ 18,448 $ 4,513 $ 847 $ 43,436 $ 28,388 $ 6,733 $ 135,494 Charge-offs (1,338) — — (147) (315) (17,086) — (18,886) Recoveries 825 468 — — 610 5,416 — 7,319 Increase (decrease) in Provision (778) 1,665 1,311 120 1,146 11,881 (1,945) 13,400 Balance at end of period $ 31,838 $ 20,581 $ 5,824 $ 820 $ 44,877 $ 28,599 $ 4,788 $ 137,327 The disaggregation of the Allowance and recorded investment in loans by impairment methodology as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Individually evaluated for impairment $ 448 $ 57 $ — $ — $ 409 $ — $ — $ 914 Collectively evaluated for impairment 32,988 20,757 6,218 528 43,980 33,993 1,872 140,336 Balance at end of period $ 33,436 $ 20,814 $ 6,218 $ 528 $ 44,389 $ 33,993 $ 1,872 $ 141,250 Loans and leases: Individually evaluated for impairment $ 12,785 $ 7,650 $ 2,001 $ — $ 17,118 $ — $ — $ 39,554 Collectively evaluated for impairment 2,956,452 2,884,103 610,793 161,314 4,296,371 1,651,877 — 12,560,910 Balance at end of period $ 2,969,237 $ 2,891,753 $ 612,794 $ 161,314 $ 4,313,489 $ 1,651,877 $ — $ 12,600,464 December 31, 2017 Commercial Lending Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Residential Consumer Unallocated Total Allowance for loan and lease losses: Individually evaluated for impairment $ 4 $ 6 $ — $ — $ 484 $ — $ — $ 494 Collectively evaluated for impairment 34,002 18,038 6,817 611 42,368 31,249 3,674 136,759 Balance at end of period $ 34,006 $ 18,044 $ 6,817 $ 611 $ 42,852 $ 31,249 $ 3,674 $ 137,253 Loans and leases: Individually evaluated for impairment $ 18,183 $ 10,636 $ — $ — $ 16,530 $ — $ — $ 45,349 Collectively evaluated for impairment 3,117,083 2,656,961 632,911 165,066 4,073,523 1,586,476 — 12,232,020 Balance at end of period $ 3,135,266 $ 2,667,597 $ 632,911 $ 165,066 $ 4,090,053 $ 1,586,476 $ — $ 12,277,369 Credit Quality The Company performs an internal loan review and grading 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 procedures is to identify, in a timely manner, existing or emerging credit quality problems so that appropriate steps can be initiated to avoid or minimize future losses. Loans subject to grading include: commercial and industrial loans, commercial and standby letters of credit, installment loans to businesses or individuals for business and commercial purposes, commercial real estate loans, overdraft lines of credit, commercial credit cards, and other credits as may be determined. Loans which are not subject to grading include loans that are 100% sold with no recourse to the Company, consumer installment loans, indirect automobile loans, consumer credit cards, business credit cards, home equity lines of credit and residential real estate loans. Residential real estate and consumer loans are underwritten primarily on the basis of credit bureau scores, debt-service-to-income ratios, and collateral quality and loan to value ratios. A 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 eight factors of a borrower: character, earnings and operating cash flow, asset and liability structure, debt capacity, financial reporting, management and controls, borrowing entity, and industry and operating environment. Pass – “Pass” (uncriticized) loans and leases, are not considered to carry greater than normal risk. The borrower has the apparent ability to satisfy obligations to the Company, and therefore no loss in ultimate collection is anticipated. Special Mention – Loans and leases that have potential weaknesses deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for assets or in the institution’s credit position at some future date. Special mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Substandard – Loans and leases that are inadequately protected by the current financial condition and paying capacity of the obligor or by any collateral pledged. Loans and leases so classified must have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the distinct possibility that the bank may sustain some loss if the deficiencies are not corrected. Doubtful – Loans and leases that have weaknesses found in substandard borrowers with the added provision that the weaknesses make collection of debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss – Loans and leases classified as loss are considered uncollectible and of such little value that their continuance as an asset is not warranted. This classification does not mean that the loan or lease has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future. The credit risk profiles by internally assigned grade for loans and leases as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Total Grade: Pass $ 2,831,415 $ 2,797,282 $ 608,201 $ 159,501 $ 6,396,399 Special mention 64,966 69,992 1,630 1,544 138,132 Substandard 72,664 24,479 2,963 269 100,375 Doubtful 192 — — — 192 Total $ 2,969,237 $ 2,891,753 $ 612,794 $ 161,314 $ 6,635,098 December 31, 2017 Commercial Commercial and Real Lease (dollars in thousands) Industrial Estate Construction Financing Total Grade: Pass $ 3,035,121 $ 2,619,494 $ 628,112 $ 162,849 $ 6,445,576 Special mention 43,435 26,248 2,377 1,816 73,876 Substandard 54,996 21,855 2,422 401 79,674 Doubtful 1,714 — — — 1,714 Total $ 3,135,266 $ 2,667,597 $ 632,911 $ 165,066 $ 6,600,840 There were no loans and leases graded as Loss as of September 30, 2018 and December 31, 2017. The credit risk profiles based on payment activity for loans and leases that were not subject to loan grading as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 (dollars in thousands) Residential Consumer Consumer - Auto Credit Cards Total Performing $ 4,297,918 $ 235,072 $ 1,049,219 $ 325,317 $ 5,907,526 Non-performing and delinquent 15,571 5,505 33,082 3,682 57,840 Total $ 4,313,489 $ 240,577 $ 1,082,301 $ 328,999 $ 5,965,366 December 31, 2017 (dollars in thousands) Residential Consumer Consumer - Auto Credit Cards Total Performing $ 4,073,834 $ 231,023 $ 1,001,085 $ 324,781 $ 5,630,723 Non-performing and delinquent 16,219 3,335 22,612 3,640 45,806 Total $ 4,090,053 $ 234,358 $ 1,023,697 $ 328,421 $ 5,676,529 Impaired and Nonaccrual Loans and Leases The Company evaluates certain loans and leases individually for impairment. A loan or lease is considered to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan or lease. An allowance for impaired commercial loans, including commercial real estate and construction loans, is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. An allowance for impaired residential loans is measured based on the estimated fair value of the collateral, less any selling costs. Management exercises significant judgment in developing these estimates. The Company generally places a loan 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. It is the Company’s policy to charge off a loan when the facts indicate that the loan is considered uncollectible. The aging analyses of past due loans and leases as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 Accruing Loans and Leases Greater Total Non Than or Total Accruing

loans modified in a troubled debt restructuring (“TDR”) may involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans. Additional collateral, a co-borrower, or a guarantor may be requested. Modifications of commercial real estate and construction loans in a TDR may involve reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, or substituting or adding a new borrower or guarantor. Modifications of construction loans in a TDR may also involve extending the interest-only payment period. Interest continues to accrue on the missed payments and as a result, the effective yield on the loan remains unchanged. As the forbearance period usually involves an insignificant payment delay, lease financing modifications typically do not meet the reporting criteria for a TDR. Residential real estate loans modified in a TDR may be comprised of loans where monthly payments are lowered to accommodate the borrowers' financial needs for a period of time, normally two years. Generally, consumer loans are not classified as a TDR as they are normally charged off upon reaching a predetermined delinquency status that ranges from 120 to 180 days and varies by product type. Loans modified in a TDR may already be on nonaccrual status and in some cases partial charge-offs may have already been taken against the outstanding loan balance. Loans modified in a TDR are evaluated for impairment. As a result, this may have a financial effect of increasing the specific Allowance associated with the loan. An Allowance for impaired commercial loans, including commercial real estate and construction loans, that have been modified in a TDR is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. An Allowance for impaired residential loans that have been modified in a TDR is measured based on the estimated fair value of the collateral, less any selling costs. Management exercises significant judgment in developing these estimates. The following presents, by class, information related to loans modified in a TDR during the three and nine months ended September 30, 2018 and 2017: Three Months Ended Nine Months Ended September 30, 2018 September 30, 2018 Number of Recorded Related Number of Recorded Related (dollars in thousands) Contracts Investment (1) Allowance Contracts Investment (1) Allowance Commercial and industrial — $ — $ — 1 $ 450 $ 12 Residential 3 883 30 3 883 30 Total 3 $ 883 $ 30 4 $ 1,333 $ 42 Three Months Ended Nine Months Ended September 30, 2017 September 30, 2017 Number of Recorded Related Number of Recorded Related (dollars in thousands) Contracts Investment (1) Allowance Contracts Investment (1) Allowance Commercial and industrial — $ — $ — 1 $ 1,120 $ — Residential — — — 2 661 21 Total — $ — $ — 3 $ 1,781 $ 21 (1) The recorded investment balances reflect all partial paydowns and charge-offs since the modification date and do not include TDRs that have been fully paid off, charged off, or foreclosed upon by the end of the period. The above loans were modified in a TDR through an extension of maturity dates, temporary interest-only payments, reduced payments, or below-market interest rates. The Company had commitments to extend credit, standby letters of credit, and commercial letters of credit totaling $5.9 billion and $5.6 billion as of September 30, 2018 and December 31, 2017, respectively. Of the $5.9 billion at September 30, 2018, there were commitments of $0.9 million related to borrowers who had loan terms modified in a TDR. Of the $5.6 billion at December 31, 2017, there were commitments of $1.9 million related to borrowers who had loan terms modified in a TDR. The following table presents, by class, loans modified in TDRs that have defaulted in the current period within 12 months of their permanent modification date for the periods indicated. The Company is reporting these defaulted TDRs based on a payment default definition of 30 days past due: Three Months Ended Nine Months Ended Three Months Ended Nine Months Ended September 30, 2018 September 30, 2018 September 30, 2017 September 30, 2017 Number of Recorded Number of Recorded Number of Recorded Number of Recorded (dollars in thousands) Contracts Investment (1) Contracts Investment (1) Contracts Investment (1) Contracts Investment (1) Commercial and industrial (2) — $ — 2 $ 254 — $ — 1 $ 2,496 Commercial real estate (3) — — — — — — 1 1,393 Residential (4) — — — — — — 1 510 Total — $ — 2 $ 254 — $ — 3 $ 4,399 (1) The recorded investment balances reflect all partial paydowns and charge-offs since the modification date and do not include TDRs that have been fully paid off, charged off, or foreclosed upon by the end of the period. (2) For both the nine months ended September 30, 2018 and 2017, the maturity dates for the commercial and industrial loans that subsequently defaulted were extended. (3) For the nine months ended September 30, 2017, the commercial real estate loan that subsequently defaulted was extended. (4) For the nine months ended September 30, 2017 , the residential real estate loan that subsequently defaulted was modified for interest-only payments. Foreclosure Proceedings There was one residential mortgage loan collateralized by real estate property of $0.3 million that was modified in a TDR that was in process of foreclosure as of September 30, 2018. As of December 31, 2017, there was one separate residential mortgage loan collateralized by real estate property of $0.3 million that was modified in a TDR that was in process of foreclosure. Foreclosed Property Residential real estate property held from two foreclosed residential mortgage loans included in other real estate owned and repossessed personal property shown in the unaudited interim consolidated balance sheet was $0.4 million as of September 30, 2018. Residential real estate property held from one foreclosed TDR of a residential mortgage loan included in other real estate owned and repossessed personal property shown in the consolidated balance sheet was $0.3 million as of December 31, 2017.

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 $2.7 billion and $2.3 billion as of September 30, 2018 and December 31, 2017, respectively. Servicing fees include contractually specified fees, late charges, and ancillary fees, and were $1.7 million and $1.6 million for the three months ended September 30, 2018 and 2017, respectively, and $5.3 million and $5.0 million for the nine months ended September 30, 2018 and 2017, respectively. Amortization of mortgage servicing rights (“MSRs”) was $1.0 million and $0.9 million for the three months ended September 30, 2018 and 2017, respectively, and $3.0 million and $2.8 million for the nine months ended September 30, 2018 and 2017, respectively. The estimated future amortization expenses for MSRs over the next five years are as follows: Estimated (dollars in thousands) Amortization Under one year $ 2,452 One to two years 2,157 Two to three years 1,900 Three to four years 1,671 Four to five years 1,470 The details of the Company’s MSRs are presented below: September 30, December 31, (dollars in thousands) 2018 2017 Gross carrying amount $ 63,276 $ 56,571 Less: accumulated amortization 46,339 43,375 Net carrying value $ 16,937 $ 13,196 The following table presents changes in amortized MSRs for the three and nine months ended September 30, 2018 and 2017: Three Months Ended September 30, Nine Months Ended September 30, (dollars in thousands) 2018 2017 2018 2017 Balance at beginning of period $ 17,660 $ 14,877 $ 13,196 $ 16,809 Originations 233 12 262 16 Purchases — — 6,444 — Amortization (956) (909) (2,965) (2,845) Balance at end of period $ 16,937 $ 13,980 $ 16,937 $ 13,980 Fair value of amortized MSRs at beginning of period $ 28,344 $ 23,263 $ 21,697 $ 25,160 Fair value of amortized MSRs at end of period $ 27,945 $ 21,777 $ 27,945 $ 21,777 MSRs are evaluated for impairment if events and circumstances indicate a possible impairment. No impairment of MSRs was recorded for the nine months ended September 30, 2018 and 2017. The quantitative assumptions used in determining the lower of cost or fair value of the Company’s MSRs as of September 30, 2018 and December 31, 2017 were as follows: September 30, 2018 December 31, 2017 Weighted Weighted Range Average Range Average Conditional prepayment rate 8.09 % - 19.94 % 8.59 % 8.53 % - 19.63 % 9.04 % Life in years (of the MSR) 3.35 - 7.61 7.12 3.29 - 7.15 6.76 Weighted-average coupon rate 3.97 % - 6.73 % 4.02 % 3.97 % - 6.79 % 4.04 % Discount rate 10.00 % - 10.02 % 10.00 % 10.50 % - 10.52 % 10.50 % 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 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, 2018 and December 31, 2017 were as follows: (dollars in thousands) September 30, 2018 December 31, 2017 Public deposits $ 2,162,988 $ 2,800,690 Federal Home Loan Bank 2,640,530 2,388,702 Federal Reserve Bank 969,888 914,454 ACH transactions 152,089 151,526 Interest rate swaps 25,483 27,502 Total $ 5,950,978 $ 6,282,874 As the Company did not enter into reverse repurchase agreements, no collateral was accepted as of September 30, 2018 and December 31, 2017. In addition, no debt was extinguished by in-substance defeasance. The Company did not have any repurchase agreements as of September 30, 2018 and December 31, 2017.

Regulatory Capital Requirements

Regulatory Capital Requirements
Regulatory Capital Requirements	11. 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. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of Common Equity Tier 1 (“CET1”) capital, Tier 1 capital and total capital to risk-weighted assets, as well as a minimum leverage ratio. The table below sets forth those ratios at September 30, 2018 and December 31, 2017: First Hawaiian Minimum Well- First Hawaiian, Inc. Bank Capital Capitalized (dollars in thousands) Amount Ratio Amount Ratio Ratio (1) Ratio (1) September 30, 2018: Common equity tier 1 capital to risk-weighted assets $ 1,632,669 12.09 % $ 1,629,109 12.06 % 4.50 % 6.50 % Tier 1 capital to risk-weighted assets 1,632,669 12.09 % 1,629,109 12.06 % 6.00 % 8.00 % Total capital to risk-weighted assets 1,774,519 13.14 % 1,770,959 13.11 % 8.00 % 10.00 % Tier 1 capital to average assets (leverage ratio) 1,632,669 8.42 % 1,629,109 8.41 % 4.00 % 5.00 % December 31, 2017: Common equity tier 1 capital to risk-weighted assets $ 1,633,442 12.45 % $ 1,623,455 12.37 % 4.50 % 6.50 % Tier 1 capital to risk-weighted assets 1,633,442 12.45 % 1,623,455 12.37 % 6.00 % 8.00 % Total capital to risk-weighted assets 1,771,295 13.50 % 1,761,308 13.42 % 8.00 % 10.00 % Tier 1 capital to average assets (leverage ratio) 1,633,442 8.52 % 1,623,455 8.47 % 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”). A new capital conservation buffer, comprised of CET1 capital, was established above the regulatory minimum capital requirements. This capital conservation buffer was phased in beginning January 1, 2016 at 0.625% of risk-weighted assets and will increase each subsequent year by an additional 0.625% until reaching its final level of 2.5% on January 1, 2019. As of September 30, 2018, 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, 2018, to change the capital adequacy category of the Company or the Bank.

Income Taxes
Income Taxes	12. Income Taxes On December 22, 2017, President Trump signed into law the Tax Act. The Tax Act makes many significant amendments to the Internal Revenue Code of 1986, as amended (the “Code”), including reducing the corporate tax rate from 35% to 21%, effective January 1, 2018. GAAP requires that companies record and reflect the impact of the Tax Act in their financial statements for the quarter during which the Tax Act becomes law, even if provisions of the Tax Act become effective at a future date. Accordingly, the Company reported the impact of the Tax Act on its results of operations in its consolidated financial statements for the fourth quarter and year ended December 31, 2017. The reduction in the corporate tax rate under the Tax Act required a one-time revaluation of certain tax-related assets, which resulted in the Company recording $47.6 million in additional income tax expense in our consolidated statements of income in the fourth quarter of 2017. The Company’s effective tax rate was 25.99% and 37.71% for the three months ended September 30, 2018 and 2017, respectively, and 26.00% and 37.25% for the nine months ended September 30, 2018 and 2017, respectively. The Company is subject to examination by the Internal Revenue Service (“IRS”) and tax authorities in states in which the Company has significant business operations. The tax years under examination and open for examination vary by jurisdiction. There are currently no federal examinations under way; however, tax returns for certain years are being reviewed by state jurisdictions. No material unanticipated adjustments were made by the IRS in the years most recently examined. The Company’s income tax returns for 2014 and subsequent tax years generally remain subject to examination by U.S. federal and foreign jurisdictions, and 2013 and subsequent years are subject to examination by state taxing authorities. A reconciliation of the amount of unrecognized tax benefits is as follows for the nine months ended September 30, 2018 and 2017: Nine Months Ended September 30, 2018 2017 Interest Interest and and (dollars in thousands) Tax Penalties Total Tax Penalties Total Balance at January 1, $ 130,619 $ 10,660 $ 141,279 $ 127,085 $ 9,965 $ 137,050 Additions for current year tax positions 1,213 — 1,213 1,727 — 1,727 Additions for Reorganization Transactions — — — — 226 226 Additions for prior years' tax positions: Accrual of interest and penalties — 760 760 — 295 295 Reductions for prior years' tax positions: Expiration of statute of limitations (209) (93) (302) (258) (152) (410) Other (773) — (773) — — — Balance at September 30, $ 130,850 $ 11,327 $ 142,177 $ 128,554 $ 10,334 $ 138,888 Included in the balance of unrecognized tax benefits was $15.4 million and $11.2 million of unrecognized tax benefits for the nine months ended September 30, 2018 and 2017, respectively that, if recognized, would impact the effective tax rate. In connection with the Reorganization Transactions discussed below, the Company recorded unrecognized tax benefits and interest and penalties of $121.4 million and $7.0 million, respectively, for the year ended December 31, 2016. Included in the balance of the unrecognized tax benefits as of September 30, 2018 was $93.9 million attributable to tax refund claims with respect to tax years 2005 through 2012 in the State of California. Such refund claims were filed by the Company in 2015, on behalf of the Company and its affiliates, including BOW, concerning the determination of taxes for which no benefit is currently recognized. It is reasonably possible that the amount of unrecognized tax benefits could decrease within the next 12 months by as much as $13.6 million of taxes and $5.8 million of accrued interest and penalties as a result of settlements and the expiration of the statute of limitations in various states. The Company recognizes interest and penalties attributable to both unrecognized tax benefits and undisputed tax adjustments in the provision for income taxes. For the nine months ended September 30, 2018 and 2017, the Company recorded nil and $0.4 million, respectively, of net expense attributable to interest and penalties. The Company had a liability of $12.9 million and $12.8 million as of September 30, 2018 and December 31, 2017, respectively, for accrued interest and penalties, of which $11.3 million and $10.7 million as of September 30, 2018 and December 31, 2017, respectively, were attributable to unrecognized tax benefits and the remainder was attributable to tax adjustments which are not expected to be in dispute. Prior to the Reorganization Transactions, the Company filed consolidated U.S. Federal and combined state tax returns that incorporated the tax receivables and unrecognized tax benefits of FHB and BOW. The consummation of the Reorganization Transactions did not relieve the Company of the pre-Reorganization Transactions tax receivables and unrecognized tax benefits recognized by BOW that were included in the Company's consolidated and combined tax returns. As of September 30, 2018, the Company maintained balances of $93.9 million related to current tax receivables, $116.5 million related to unrecognized tax benefits, and an indemnification receivable of $22.6 million. Additionally, in connection with the Reorganization Transactions, the Company incurred certain tax-related liabilities related to the distribution of its interest in BWHI amounting to $95.4 million. The amount necessary to pay the distribution taxes (net of the expected federal tax benefit of $33.4 million) was paid by BNPP to the Company on April 1, 2016. The Company reported total distribution taxes of $92.1 million in the 2016 tax returns of various state and local jurisdictions, and reimbursed BWHI approximately $2.1 million pursuant to a tax sharing agreement entered into on April 1, 2016 and pursuant to certain tax allocation agreements entered into among the parties. The Company expects that any future adjustment to such taxes will be similarly reimbursed to, or funded by, BWHI or its affiliates. Accordingly, the assumption of the pre-Reorganization Transactions tax receivables, unrecognized tax benefits and distribution tax liabilities and the offsetting indemnification receivables or payables were reflected as equity contributions and distributions on April 1, 2016. The reimbursement of distribution taxes to BWHI was also reflected as an adjustment to equity. If there are any future adjustments to the indemnified tax receivables or unrecognized tax benefits, an offsetting adjustment to the indemnification receivables or payables will be recorded to the provision for income taxes and other noninterest income or expense. With the completion of the February 2017 offering, BNPP’s beneficial ownership of the Company fell below 80% of the total outstanding FHI common stock. As a result, the Company ceased to be a member of the BNPP USA affiliated group and began filing stand-alone returns with the IRS and certain state jurisdictions. With the completion of the May 2018 offering and concurrent share repurchase, BNPP’s beneficial ownership of the Company fell below 50% of the total outstanding FHI common stock, resulting in the Company filing stand-alone returns in all remaining jurisdictions.

Derivative Financial Instruments
Derivative Financial Instruments	13. 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 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 notional amounts and fair values of derivatives held by the Company as of September 30, 2018 and December 31, 2017: September 30, 2018 December 31, 2017 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 $ 192,880 $ 504 $ (135) $ 194,687 $ — $ (2,032) Derivatives not designated as hedging instruments: Interest rate swaps 2,166,248 1,540 (28,388) 1,820,442 14,658 (13,017) Funding swap 59,770 — (3,385) 43,113 — (5,439) Foreign exchange contracts 5,301 — (34) 3,658 24 — (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. The amount of initial margin cash collateral posted by the Company was $1.4 million and $2.9 million as of September 30, 2018 and December 31, 2017, respectively. Effective January 3, 2017, the Chicago Mercantile Exchange (“CME”) amended its rulebook to legally characterize variation margin payments, for derivative contracts that are referred to as settled-to-market (“STM”), as settlements of the derivative’s mark-to-market exposure and not collateral. Based on these changes, the Company has treated the CME variation margin as a settlement, which has resulted in a decrease in our cash collateral, and a corresponding decrease in our derivative asset and liability. The change was applied prospectively effective January 3, 2017. As of September 30, 2018 and December 31, 2017, the CME variation margin was $0.6 million and $3.1 million, respectively. Effective January 16, 2018, the London Clearing House (“LCH”) also amended its rulebook to legally characterize variation margin payments, for derivative contracts that are referred to as STM, as settlements of the derivative’s mark-to-market exposure and not collateral. Consistent with the CME’s amended requirements discussed above, the Company has treated the LCH variation margin as a settlement, which has resulted in a decrease in our cash collateral, and a corresponding decrease in our derivative asset and liability. The change was applied prospectively effective January 16, 2018. As of September 30, 2018, the LCH variation margin was $25.7 million. As of September 30, 2018, the Company pledged $23.5 million in financial instruments and $2.0 million in cash as collateral for interest rate swaps. As of September 30, 2018, 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 December 31, 2017, the Company pledged $22.6 million in financial instruments and $4.9 million in cash as collateral for interest rate swaps. As of December 31, 2017, the cash collateral includes the excess initial margin for interest rate swaps cleared through clearinghouses, the LCH variation margin which was not treated as settlements prior to January 16, 2018 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, 2018, the Company carried interest rate swaps with notional amounts totaling $42.9 million with a positive fair value of $0.5 million and a negative fair value of nil that were categorized as fair value hedges for commercial and industrial loans and commercial real estate loans. The Company received 6-month London Interbank Offered Rate (“LIBOR”) and paid fixed rates ranging from 2.59% to 3.44%. The swaps mature between 2019 and 2023. At December 31, 2017, the Company carried interest rate swaps with notional amounts totaling $44.7 million with a positive fair value of nil and a negative fair value of $0.5 million that were categorized as fair value hedges for commercial and industrial loans and commercial real estate loans. The following table shows the net gains and losses recognized in income related to derivatives in fair value hedging relationships for the three and nine months ended September 30, 2018 and 2017: Three Months Ended Nine Months Ended September 30, September 30, (dollars in thousands) 2018 2017 2018 2017 Interest expense recorded in net interest income $ (30) $ (142) $ (203) $ (511) Gains (losses) recorded in noninterest income: Recognized on derivatives 273 150 1,231 274 Recognized on hedged item (261) (224) (1,348) (222) Net gains (losses) recognized on fair value hedges (ineffective portion) 12 (74) (117) 52 Net losses recognized on fair value hedges $ (18) $ (216) $ (320) $ (459) Cash Flow Hedges The Company utilizes interest rate swaps to reduce exposure to interest rates associated with short-term fixed-rate liabilities. The Company enters into interest rate swaps paying fixed rates and receiving LIBOR. The LIBOR index will correspond to the short-term fixed-rate nature of the liabilities being hedged. If interest rates rise, the increase in interest received on the swaps will offset increases in interest costs associated with these liabilities. By hedging with interest rate swaps, the Company minimizes the adverse impact on interest expense associated with increasing rates on short-term liabilities. The interest rate swaps are designated and qualify as cash flow hedges. The effective portion of the gain or loss on the interest rate swaps is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. There were no recognized expenses related to the ineffective portion of the change in fair value of derivatives designated as a cash flow hedge for the three and nine months ended September 30, 2018 and 2017. As of September 30, 2018 and December 31, 2017, the Company carried two interest rate swaps with notional amounts totaling $150.0 million, with a negative fair value of $0.1 million as of September 30, 2018 and a negative fair value of $1.5 million as of December 31, 2017, in order to reduce exposure to interest rate increases associated with short-term fixed-rate liabilities. The swaps mature in December 2018. The Company received 6-month LIBOR and paid fixed rates ranging from 2.98% to 3.03%. The interest rate swaps designated as cash flow hedges resulted in net interest expense of $0.2 million and $0.6 million during the three months ended September 30, 2018 and 2017, respectively, and $1.1 million and $1.9 million during the nine months ended September 30, 2018 and 2017, respectively. The following table summarizes the effect of cash flow hedging relationships for the three and nine months ended September 30, 2018 and 2017: Three Months Ended Nine Months Ended September 30, September 30, (dollars in thousands) 2018 2017 2018 2017 Pretax gains recognized in other comprehensive income on derivatives (effective portion) $ 178 $ 675 $ 1,341 $ 1,531 There were no gains or losses reclassified from accumulated other comprehensive loss to earnings during the three and nine months ended September 30, 2018 and 2017. 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, 2018 and 2017: Net gains (losses) recognized Three Months Ended Nine Months Ended in the consolidated statements September 30, September 30, (dollars in thousands) of income line item 2018 2017 2018 2017 Derivatives Not Designated As Hedging Instruments: Interest rate swaps Other noninterest income $ 112 $ 234 $ 744 $ 587 Funding swap Other noninterest income (43) (41) (123) (74) Foreign exchange contracts Other noninterest income 34 (149) (58) 78 As of September 30, 2018, the Company carried multiple interest rate swaps with notional amounts totaling $2.2 billion, including $2.1 billion related to the Company’s customer swap program, with a positive fair value of $1.5 million and a negative fair value of $28.4 million. The Company received 1-month and 3-month LIBOR and paid fixed rates ranging from 2.02% to 5.78%. The swaps mature between December 2018 and April 2037. As of December 31, 2017, the Company carried multiple interest rate swaps with notional amounts totaling $1.8 billion, including $1.7 billion related to the Company’s customer swap program, with a positive fair value of $14.7 million and a negative fair value of $13.0 million. The Company received 1-month and 3-month LIBOR and paid fixed rates ranging from 1.36% to 5.33%. These swaps resulted in net interest expense of $0.1 million and $0.2 million for the three months ended September 30, 2018 and 2017, respectively, and $0.4 million and $0.7 million for the nine months ended September 30, 2018 and 2017, respectively. 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 $1.3 million for the three months ended September 30, 2018 and 2017, respectively, and $5.3 million and $5.9 million for the nine months ended September 30, 2018 and 2017, respectively. Interest rate swaps related to the program had asset fair values of $1.5 million and $14.7 million as of September 30, 2018 and December 31, 2017, respectively, and liability fair values of $27.8 million and $11.7 million as of September 30, 2018 and December 31, 2017, respectively. In conjunction with the 2016 sale of Class B restricted shares of common stock issued by Visa, 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. On June 28, 2018, Visa additionally funded its litigation escrow account, thereby reducing each member bank’s Class B conversion rate to unrestricted Class A common shares. Accordingly, on July 5, 2018, Visa announced a decrease in conversion rate from 1.6483 to 1.6298 effective June 28, 2018. In July 2018, the Company made a payment of approximately $0.7 million to the buyer as a result of the reduction in the Visa Class B conversion rate. 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 $3.4 million and $5.4 million was included in the unaudited interim consolidated balance sheets at September 30, 2018 and December 31, 2017, respectively, to provide for the fair value of this liability. There were no sales of these shares prior to 2016. See “Note 18. 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 $0.5 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 $0.1 million were recognized during both the nine months ended September 30, 2018 and 2017 . Credit-Risk Related Contingent Features Certain 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 $0.2 million and $4.5 million at September 30, 2018 and December 31, 2017, respectively, for which we posted $0.5 million and $4.8 million, respectively, in collateral in the normal course of business. If the Company’s credit rating had been downgraded as of September 30, 2018 and December 31, 2017, we may have been required to settle the contract in an amount equal to its fair value.

Commitments and Contingent Liabilities
Commitments and Contingent Liabilities	14. Commitments and Contingent Liabilities Contingencies On January 27, 2017, a putative class action lawsuit was filed by a Bank customer alleging that FHB improperly charges an overdraft fee in circumstances where an account had sufficient funds to cover the transaction at the time the transaction is authorized but not at the time the transaction is presented for payment, and that this practice constitutes an unjust and deceptive trade practice and a breach of contract. The lawsuit further alleged that FHB’s practice of assessing a one-time continuous negative balance overdraft fee on accounts remaining in a negative balance for a seven-day period constitutes a usurious interest charge and an unfair and deceptive trade practice. On October 2, 2018, the parties reached an agreement in principle to resolve this class action lawsuit. In connection with the anticipated settlement agreement, the Company recorded an expense of approximately $4.1 million during the three months ended September 30, 2018. The settlement agreement will be subject to court approval. In addition to the litigation noted above, various other 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 $99.4 million and $49.1 million at September 30, 2018 and December 31, 2017, 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 $17.8 million as of both September 30, 2018 and December 31, 2017. 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, 2018 have maturities ranging from October 2018 to March 2021. 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, 2018 and December 31, 2017 were as follows: September 30, December 31, (dollars in thousands) 2018 2017 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 5,679,106 $ 5,401,763 Standby letters of credit 193,089 161,798 Commercial letters of credit 4,509 5,540 Guarantees The Company sells residential mortgage loans in the secondary market primarily to The Federal National Mortgage Association (“FNMA” or “Fannie Mae”) and The Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”) 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 13. Derivative Financial Instruments” for more information. Reorganization Transactions In connection with the Reorganization Transactions as discussed in Note 1, FHI (formerly BancWest) distributed its interest in BWHI (including BOW) to BNPP so that BWHI was held directly by BNPP. BWHI is now held indirectly by BNPP through its intermediate holding company. 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, 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
Revenue from Contracts with Customers	15. Revenue from Contracts with Customers As noted in Note 1, the Company adopted the provisions of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), on January 1, 2018. Results for reporting periods beginning after December 31, 2017 are presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with Topic 605. 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 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, 2018 Treasury Retail Commercial and (dollars in thousands) Banking Banking Other Total Net interest income (1) $ 111,804 $ 29,639 $ (185) $ 141,258 Service charges on deposit accounts 7,494 4 435 7,933 Credit and debit card fees — 19,602 1,783 21,385 Other service charges and fees 5,161 1,063 374 6,598 Trust and investment services income 7,487 — — 7,487 Other 134 1,427 255 1,816 Not in scope of Topic 606 (1) 2,400 (4,295) 4,081 2,186 Total noninterest income 22,676 17,801 6,928 47,405 Total revenue $ 134,480 $ 47,440 $ 6,743 $ 188,663 (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. Nine Months Ended September 30, 2018 Treasury Retail Commercial and (dollars in thousands) Banking Banking Other Total Net interest income (1) $ 332,731 $ 86,320 $ 3,282 $ 422,333 Service charges on deposit accounts 22,077 11 1,521 23,609 Credit and debit card fees — 58,409 5,380 63,789 Other service charges and fees 15,004 2,997 1,527 19,528 Trust and investment services income 23,429 — — 23,429 Other 430 5,224 924 6,578 Not in scope of Topic 606 (1) 6,626 (7,377) 9,720 8,969 Total noninterest income 67,566 59,264 19,072 145,902 Total revenue $ 400,297 $ 145,584 $ 22,354 $ 568,235 (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, 2018 and 2017, 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 a 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 broker dealer fees which represent revenue earned from buying and selling securities on behalf of customers. Such fees are recognized at the end of a valuation period or concurrently with the execution of a buy or sell transaction. 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, 2018 and December 31, 2017, the Company had contract liabilities of $2.8 million and $3.4 million, respectively, which will be recognized over the remaining term of the respective contracts with the vendors. For the three and nine months ended September 30, 2018, the Company recognized revenues 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, 2018 and December 31, 2017, there were no 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, 2018. 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
Fair Value	18. Fair Value The Company determines the fair values of its financial instruments based on the requirements established in Accounting Standards Codification (“ASC”) 820, Fair Value Measurements , which provides a framework for measuring fair value under GAAP and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 defines fair value as the exit price, the price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. Fair Value Hierarchy ASC 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. ASC 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, interest rate 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, 2018 and December 31, 2017, 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 in the fair value hierarchy. 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 in the fair value hierarchy. 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. On July 5, 2018, Visa announced a decrease in conversion rate from 1.6483 to 1.6298 effective June 28, 2018. The Visa derivative of $3.4 million and $5.4 million was included in the unaudited interim consolidated balance sheets at September 30, 2018 and December 31, 2017, 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, 2018 and December 31, 2017 are summarized below: Fair Value Measurements as of September 30, 2018 Quoted Prices in Significant Active Markets for Other Significant Identical Assets Observable Unobservable (dollars in thousands) (Level 1) Inputs (Level 2) Inputs (Level 3) Total Assets U.S. Treasury securities $ — $ 383,890 $ — $ 383,890 Government-sponsored enterprises debt securities — 237,217 — 237,217 Government agency mortgage-backed securities (1) — 419,293 — 419,293 Government-sponsored enterprises mortgage-backed securities (1) — 154,133 — 154,133 Collateralized mortgage obligations: Government agency — 2,753,966 — 2,753,966 Government-sponsored enterprises — 627,239 — 627,239 Debt securities issued by states and political subdivisions — 19,563 — 19,563 Total available-for-sale securities — 4,595,301 — 4,595,301 Other assets (2) — 2,044 — 2,044 Liabilities Other liabilities (3) — (28,557) (3,385) (31,942) Total $ — $ 4,568,788 $ (3,385) $ 4,565,403 Fair Value Measurements as of December 31, 2017 Quoted Prices in Significant Active Markets for Other Significant Identical Assets Observable Unobservable (dollars in thousands) (Level 1) Inputs (Level 2) Inputs (Level 3) Total Assets U.S. Treasury securities $ — $ 392,255 $ — $ 392,255 Government-sponsored enterprises debt securities — 242,601 — 242,601 Government agency mortgage-backed securities (1) — 351,390 — 351,390 Government-sponsored enterprises mortgage-backed securities (1) — 174,741 — 174,741 Collateralized mortgage obligations: Government agency — 3,290,474 — 3,290,474 Government-sponsored enterprises — 762,718 — 762,718 Debt securities issued by states and political subdivisions — 20,479 — 20,479 Total available-for-sale securities — 5,234,658 — 5,234,658 Other assets (2) — 14,682 — 14,682 Liabilities Other liabilities (3) — (15,049) (5,439) (20,488) Total $ — $ 5,234,291 $ (5,439) $ 5,228,852 (1) Backed by residential real estate.

Changes in Fair Value Levels For the three and nine months ended September 30, 2018, there were no transfers between fair value hierarchy levels. The changes in Level 3 liabilities measured at fair value on a recurring basis for the three and nine months ended September 30, 2018 are summarized below.

(2) In connection with the prospective adoption of ASU 2016-01 on July 1, 2018, the valuation methodology used to estimate the fair value of loans was changed to conform to an exit price notion. The fair value estimate at December 31, 2017 has not been revised to reflect application of the modified methodology. (3) Excludes deposit liabilities with no defined or contractual maturity of $13.4 billion as of both September 30, 2018 and December 31, 2017. (4) Excludes capital lease obligations of $26 thousand at September 30, 2018. Unfunded loan and lease commitments and letters of credit are not included in the tables above. As of September 30, 2018 and December 31, 2017, the Company had $5.9 billion and $5.6 billion of unfunded loan and lease commitments and letters of credit. 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 $11.8 million and $11.7 million at September 30, 2018 and December 31, 2017, 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. Impaired loans A large portion of the Company’s impaired loans are collateral dependent and are measured at fair value on a nonrecurring basis using collateral values as a practical expedient. The fair values of collateral for impaired loans are primarily based on real estate appraisal reports prepared by third-party appraisers less disposition costs, present value of the expected future cash flows or the loan’s observable market price. Certain loans are measured based on the present value of expected future cash flows, discounted at the loan’s effective rate, which is not a fair value measurement. The Company measures the impairment on certain loans and leases by performing a lower-of-cost-or-fair-value analysis. If impairment is determined by the value of the collateral or an observable market price, it is written down to fair value on a nonrecurring basis as Level 3. 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, 2018 and December 31, 2017: (dollars in thousands) Level 1 Level 2 Level 3 September 30, 2018 Impaired loans $ — $ — $ 402 December 31, 2017 Impaired loans $ — $ — $ 87 Total losses on impaired loans were $0.1 million and $0.2 million for the three months ended September 30, 2018 and 2017, respectively and $0.6 million and $0.7 million for the nine months ended September 30, 2018 and 2017, respectively. For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of September 30, 2018 and December 31, 2017, the significant unobservable inputs used in the fair value measurements were as follows: Quantitative Information about Level 3 Fair Value Measurements at September 30, 2018 Significant Range (dollars in thousands) Fair value Valuation Technique Unobservable Input (Weighted Average) Impaired loans $ 402 Appraisal Value Appraisal Value n/m (1) Other liabilities $ (3,385) Discounted Cash Flow Expected Conversion Rate 1.6298 Expected Term 4 years Growth Rate 15% Quantitative Information about Level 3 Fair Value Measurements at December 31, 2017 Range (dollars in thousands) Fair value Valuation Technique Unobservable Input (Weighted Average) Impaired loans $ 87 Appraisal Value Appraisal Value n/m (1) Other liabilities $ (5,439) Discounted Cash Flow Expected Conversion Rate 1.6483 Expected Term 4 years Growth Rate 15% (1) The fair value of these assets is determined based on appraised values of collateral or broker price opinions, the range of which is not meaningful to disclose.

Reportable Operating Segments

Reportable Operating Segments
Reportable Operating Segments	19. 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 loan and lease 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 loan and lease losses to each segment based on management’s estimate of the inherent loss content in each of the specific loan and lease portfolios. 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, 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 60 banking locations throughout the State of Hawaii, Guam, and Saipan. Commercial Banking Commercial Banking offers products that include corporate banking, residential and commercial real estate loans, commercial lease financing, auto dealer financing, 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. The following tables present selected business segment financial information for the periods indicated.

Organization and Basis of Presentation
Organization and Basis of Presentation	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 to consumer and commercial customers including loans, deposit products, wealth management, insurance, trust, retirement planning, credit card and merchant processing services. 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, 2017. 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.
Reorganization Transactions	Reorganization Transactions In connection with FHI’s initial public offering (“IPO”) in August 2016 in which BNP Paribas (“BNPP”) sold approximately 17% of its interest in FHI, BNPP announced its intent to sell a controlling interest in FHI, including FHI’s wholly owned subsidiary FHB, over time, subject to market conditions and other considerations. On April 1, 2016, a series of reorganization transactions (the “Reorganization Transactions”) were undertaken to facilitate the IPO. As part of the Reorganization Transactions, FHI, which was then known as BancWest Corporation (“BancWest”), formed a new bank holding company, BancWest Holding Inc. (“BWHI”), a Delaware corporation and a direct wholly owned subsidiary of BancWest, and contributed 100% of its interest in Bank of the West (“BOW”), as well as other assets and liabilities not related to FHB, to BWHI. Following the contribution of BOW to BWHI, BancWest distributed its interest in BWHI to BNPP. As part of these transactions, BancWest amended its certificate of incorporation to change its name to “First Hawaiian, Inc.”, with First Hawaiian Bank remaining as the only direct wholly owned subsidiary of FHI. On July 1, 2016, in order to comply with the Board of Governors of the Federal Reserve System’s requirement (under Regulation YY) applicable to BNPP that a foreign banking organization with $50 billion or more in U.S. non-branch assets as of June 30, 2015 establish a U.S. intermediate holding company and hold its interest in the substantial majority of its U.S. subsidiaries through the intermediate holding company by July 1, 2016, FHI became an indirect subsidiary of BNP Paribas USA, Inc. (“BNP Paribas USA”), BNPP’s U.S. intermediate holding company. As part of that reorganization, FHI became a direct wholly owned subsidiary of BancWest Corporation (“BWC”), a direct wholly owned subsidiary of BNP Paribas USA. As used herein, “BWC” refers, for all periods beginning April 1, 2016, to BancWest Corporation, a Delaware corporation and indirect wholly owned subsidiary of BNPP. On August 4, 2016, FHI’s common stock began trading on the NASDAQ Global Select Market (“NASDAQ”) under the ticker symbol “FHB”. On August 9, 2016, the IPO of 24,250,000 shares of FHI common stock, which included the full exercise of the underwriters’ option to purchase an additional 3,163,043 shares, at a price to the public of $23.00 per share was completed. On February 17, 2017, a secondary offering of 28,750,000 shares of FHI common stock, which included the full exercise of the underwriters’ option to purchase an additional 3,750,000 shares, at a price to the public of $32.00 per share was completed. On May 10, 2018, a secondary offering of 15,300,000 shares of FHI common stock at a price to the public of $27.75 per share was completed. Concurrently with the secondary offering completed on May 10, 2018, FHI entered into a share repurchase agreement with BWC and completed the repurchase of 2,968,069 shares of FHI common stock at $27.56 per share, the per share price paid by the underwriters to BWC in the concurrent public offering. On June 8, 2018, the underwriters’ exercised their full option to purchase an additional 1,530,000 shares of FHI common stock at $27.56 per share. On August 1, 2018, a secondary offering of 20,000,000 shares of FHI common stock at a price to the public of $27.90 per share was completed. Concurrently with the secondary offering completed on August 1, 2018, FHI entered into a share repurchase agreement with BWC and completed the repurchase of 1,801,801 shares of FHI common stock at $27.75 per share, the per share price paid by the underwriters to BWC in the concurrent public offering. Lastly, on September 10, 2018, in a secondary offering, BWC sold 20,000,000 shares of FHI common stock at a variable price to the public. The per share price paid in the offering to BWC by the underwriters was $28.70. FHI did not receive any of the proceeds from the sales of shares of FHI common stock in the secondary offerings completed on September 10, 2018, August 1, 2018, May 10, 2018 or February 17, 2017 or the IPO on August 9, 2016. As of September 30, 2018, BNPP remained the beneficial owner of approximately 18% of FHI’s outstanding common stock.
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.
Correction of an Immaterial Error to the Financial Statements	Correction of an Immaterial Error to the Financial Statements Subsequent to the issuance of the Company’s unaudited interim September 30, 2017 consolidated financial statements, the Company’s management determined that certain expenses related to the Company’s card rewards program were incorrectly offset against credit and debit card fee income and credit card interchange assessment fees were incorrectly classified in card rewards program expense instead of credit and debit card fee income in the consolidated statements of income for the three and nine months ended September 30, 2017. For the three and nine months ended September 30, 2017, income from service charges on deposit accounts was overstated by $0.2 million and $0.5 million, respectively, credit and debit card fee income was understated by $1.3 million and $5.0 million, respectively, occupancy expense was understated by $0.4 million and $1.2 million, respectively, and card rewards program expense was understated by $0.7 million and $3.3 million, respectively. As a result, certain noninterest income and noninterest expense amounts have been restated from the amounts previously reported to correct the classification errors. There was no change to net income or earnings per share as previously reported as a result of these errors. Management has evaluated the materiality of these errors on its prior period financial statements from a quantitative and qualitative perspective, and has concluded that these errors were not material to the prior periods.
Accounting Standard Adopted in 2018 and Recent Accounting Pronouncements	Accounting Standards Adopted in 2018 In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) . This guidance requires entities to recognize revenues when they transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the provisions of ASU No. 2014-09 on January 1, 2018. The Company adopted the new guidance using the modified retrospective transition approach, in which the guidance would only be applied to existing contracts in effect at January 1, 2018 and new contracts entered into after this date. Most of the Company’s revenue is comprised of net interest income on loans, leases, investment securities and deposits, all of which is explicitly out of scope of the new revenue recognition guidance. Management conducted an assessment of the revenue streams that were potentially affected by the new guidance and reviewed contracts in scope to ensure compliance with the new guidance. These contracts included those related to credit and debit card fees, service charges and fees on deposit accounts, and trust and investment services fees. The adoption of ASU No. 2014-09 did not have a material impact on the Company’s consolidated financial statements. However, additional disclosures required by the standard have been included in “Note 15. Revenue from Contracts with Customers” to the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . This guidance requires entities to report the service cost component of net periodic benefit cost in the same line item as other compensation costs arising from services rendered by pertinent employees during the reporting period. The other components of net periodic benefit costs are to be presented in the income statement separately from the service cost component. The Company adopted the provisions of ASU No. 2017-07 on January 1, 2018 and applied the guidance retrospectively to all periods for which a statement of income is presented. The Company continues to record the service cost component of net periodic benefit cost in salaries and employee benefits expense; however, all other components of net periodic benefit cost are now recorded in other noninterest expense. The Company elected to use the practical expedient which permits entities to estimate amounts for comparative periods using the information previously disclosed in the Company’s pension and other postretirement benefit plan disclosure as such amounts are not material. The adoption of ASU No. 2017-07 did not have a material impact on the Company’s consolidated financial statements. See “Note 17. Benefit Plans” for required disclosures. In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718), Scope of Modification Accounting. This guidance applies to entities that change the terms or conditions of a share-based payment award. This guidance clarifies when an entity should account for a change as a modification. Modification accounting will be required only if the fair value, the vesting conditions or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The Company adopted the provisions of ASU No. 2017-09 on January 1, 2018. The adoption of ASU No. 2017-09 did not have a material impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This guidance provided entities with an option to reclassify tax effects that were stranded in accumulated other comprehensive income, pursuant to the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), to retained earnings. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. However, this guidance may be early adopted in any interim or annual period for which financial statements have not yet been issued and applied either in the period of adoption or retrospectively to each period in which the effect of the change in the corporate tax rate in the Tax Act is recognized. The Company elected to early adopt the provisions of ASU No. 2018-02 on January 1, 2018 and reflected the reclassification related to the Tax Act in the period of adoption. The amount of the reclassification reflected the impact of the Tax Act that was signed into law on December 22, 2017 which reduced the corporate tax rate from 35% to 21%. The result of the early adoption of ASU No. 2018-02 was to reclassify a credit balance of $20.1 million from accumulated other comprehensive loss to retained earnings as of January 1, 2018. The Company utilizes a security-by-security approach to releasing income tax effects from accumulated other comprehensive loss. The adoption of ASU No. 2018-02 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 February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance provides that lessees will be required to recognize the following for all operating leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee's obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements to Topic 842, Leases . Specifically, entities may elect not to recast comparative periods presented when transitioning to Topic 842 and lessors may elect not to separate lease and nonlease components when certain conditions are met. The Company expects to elect the practical expedient to not recast comparative periods upon the adoption of ASU No. 2016-02 on January 1, 2019. As lessee, the Company has lease agreements for branch premises, ATM locations and information technology equipment that are currently considered operating leases, and therefore, are not recognized on the Company’s consolidated balance sheets. The Company has formed a working group comprised of teams from different disciplines, including finance, bank properties and information technology. The Company has also engaged a software vendor to assist in complying with the new lease accounting requirements. The FASB has made available several practical expedients to assist entities with adoption. In addition to the transition practical expedient noted above, the Company expects to elect the package of practical expedients which among other things, would require no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for existing leases. Additionally, the Company does not plan to elect the practical expedient to use hindsight in determining the lease term and in assessing impairment of right-of-use assets. While the Company has not yet quantified the impact to the consolidated balance sheet upon the adoption of this new guidance, the Company expects to report increased assets and liabilities as a result of recognizing right-of-use assets and lease liabilities related to the Company’s operating lease agreements noted above. However, the Company does not expect the adoption of ASU No. 2016-02 will have a material impact on its consolidated statements of income as the majority of its leases will remain operating in nature. As such, the expense recognition will be similar to previously required straight-line expense treatment. In conjunction with the Company’s adoption of ASU No. 2016-02, management is also assessing internal controls to ensure that complete, accurate and up-to-date records of all lease agreements are not only available at commencement of a lease, but also throughout the term of the lease agreement. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments . This guidance eliminates the probable recognition threshold for credit losses on financial assets measured at amortized cost. For loans and held-to-maturity debt securities, this update requires a current expected credit loss (“CECL”) approach to determine the allowance for credit losses. CECL requires loss estimates for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. In addition, this guidance modifies the other-than-temporary impairment model for available-for-sale debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for a reversal of credit losses in future periods. This guidance requires entities to record a cumulative effect adjustment to the consolidated balance sheet as of the beginning of the first reporting period in which the guidance is effective. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted. The new guidance will require significant operational changes, particularly in data collection and analysis. The Company has formed a working group comprised of teams from different disciplines, including credit, finance and information technology, to evaluate the requirements of the new standard and the impact it will have on the Company’s current processes. Management has evaluated the Company’s existing credit loss forecasting models to determine their appropriateness for CECL, has performed a data gap analysis, and is developing analytical approaches to determine CECL model inputs. The Company has also engaged a software vendor to assist in implementing a CECL production platform. However, as the impact of adopting the new guidance is expected to be heavily influenced by an assessment of the composition, characteristics, and credit quality of the Company’s loan and investment securities portfolio as well as the economic conditions in effect at the adoption date, management is currently unable to reasonably estimate the impact of adopting the new standard. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . This guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the current two-step goodwill impairment test. This guidance provides that a goodwill impairment test be conducted by comparing the fair value of a reporting unit with its carrying amount. Entities are to recognize an impairment charge for goodwill by the amount by which the carrying amount exceeds the reporting unit’s fair value. Entities will continue to have the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. This guidance shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities . The objectives of the new guidance are to: (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities, and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Historically, the Company has participated in limited activities in fair value and cash flow hedging relationships. As a result, the adoption of ASU No. 2017-12 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This guidance is a part of the FASB’s disclosure framework project to improve disclosure effectiveness. This guidance eliminates certain disclosure requirements for fair value measurements: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, an entity’s policy for the timing of transfers between levels of the fair value hierarchy and an entity’s valuation processes for Level 3 fair value measurements. This guidance also adds new disclosure requirements for public entities: changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements of instruments held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop recurring and nonrecurring Level 3 fair value measurements, including how the weighted average is calculated. Furthermore, this guidance modifies certain requirements which will involve disclosing: transfers into and out of Level 3 of the fair value hierarchy, purchases and issuances of Level 3 assets and liabilities, and information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of ASU No. 2018-13 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . This guidance aligns the accounting for implementation costs related to a hosting arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Common examples of hosting arrangements include software as a service, platform or infrastructure as a service and other similar types of hosting arrangements. While capitalized costs related to internal-use software is generally considered an intangible asset, costs incurred to implement a cloud computing arrangement that is a service contract would typically be characterized in the company’s financial statements in the same manner as other service costs (e.g., prepaid expense). The new guidance provides that an entity would be required to amortize capitalized implementation costs over the term of the hosting arrangement on a straight-line basis unless another systematic and rational basis is more representative of the pattern in which the entity expects to benefit from access to the hosted software. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted in any annual or interim period for which financial statements have not yet been issued or made available for issuance. The Company expects to early adopt the provisions of ASU No. 2018-15 on January 1, 2019 due to the Company’s shift towards utilizing more hosting arrangements that is a service contract. Management is currently evaluating the impact that the adoption of ASU No. 2018-15 will have on the Company’s consolidated financial statements.
