Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation Bank of Hawaii Corporation (the “Parent”) is a Delaware corporation and a bank holding company headquartered in Honolulu, Hawaii. Bank of Hawaii Corporation and its subsidiaries (collectively, the “Company”) provide a broad range of financial products and services to customers in Hawaii, Guam, and other Pacific Islands. The accompanying consolidated financial statements include the accounts of the Parent and its subsidiaries. The Parent’s principal operating subsidiary is Bank of Hawaii (the “Bank”). The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period information has been reclassified to conform to the current period presentation. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full fiscal year or for any future period. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and accompanying notes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements. Variable Interest Entities Variable interests are defined as contractual ownership or other interests in an entity that change with fluctuations in an entity’s net asset value. The primary beneficiary consolidates the variable interest entity (“VIE”). The primary beneficiary is defined as the enterprise that has both (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. The Company has limited partnership interests in several low-income housing partnerships. These partnerships provide funds for the construction and operation of apartment complexes that provide affordable housing to lower-income households. If these developments successfully attract a specified percentage of residents falling in that lower-income range, state and/or federal income tax credits are made available to the partners. The tax credits are generally recognized over 10 years . In order to continue receiving the tax credits each year over the life of the partnership, the low-income residency targets must be maintained. Prior to January 1, 2015, the Company utilized the effective yield method whereby the Company recognized tax credits generally over 10 years and amortized the initial cost of the investment to provide a constant effective yield over the period that tax credits are allocated to the Company. On January 1, 2015, the Company adopted ASU No. 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects” prospectively for new investments. ASU No. 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. As permitted by ASU No. 2014-01, the Company elected to continue to utilize the effective yield method for investments made prior to January 1, 2015. Unfunded commitments to fund these low-income housing partnerships were $12.8 million and $15.2 million as of June 30, 2019 and December 31, 2018 , respectively. These unfunded commitments are unconditional and legally binding and are recorded in other liabilities in the consolidated statements of condition. See Note 6 Affordable Housing Projects Tax Credit Partnerships for more information. The Company also has limited partnership interests in solar energy tax credit partnership investments. These partnerships develop, build, own and operate solar renewable energy projects. Over the course of these investments, the Company expects to receive federal and state tax credits, tax-related benefits, and excess cash available for distribution, if any. The Company may be called to sell its interest in the limited partnerships through a call option once all investment tax credits have been recognized. Tax benefits associated with these investments are generally recognized over 6 years . Although these entities meet the definition of a VIE, the Company is not the primary beneficiary of the entities as the general partner has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. While the partnership agreements allow the limited partners, through a majority vote, to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause. The investments in these entities are initially recorded at cost, which approximates the maximum exposure to loss as a result of the Company’s involvement with these unconsolidated entities. The balance of the Company’s investments in these entities was $78.9 million and $85.9 million as of June 30, 2019 and December 31, 2018 , respectively, and is included in other assets in the consolidated statements of condition. Accounting Standards Adopted in 2019 In February 2016, the FASB issued ASU No. 2016-02, “Leases.” Under the new guidance, lessees will be required to recognize the following for all 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. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard . All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. As the Company elected the transition option provided in ASU No. 2018-11 (see below), the modified retrospective approach was applied on January 1, 2019 (as opposed to January 1, 2017). The Company also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to separate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). The Company did not elect the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of right-of-use assets. The Company has several lease agreements, such as branch locations, which are considered operating leases, and therefore, were not previously recognized on the Company’s consolidated statements of condition. The new guidance requires these lease agreements to be recognized on the consolidated statements of condition as a right-of-use asset and a corresponding lease liability. The new guidance did not have a material impact on the consolidated statements of income or the consolidated statements of cash flows. See Note 16 Leases for more information. In August 2017, the FASB issued ASU No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This ASU’s objectives 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. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018. The Company currently does not designate any derivative financial instruments as formal hedging relationships, and therefore, does not currently utilize hedge accounting. As such, ASU No. 2017-12 did not impact the Company’s Consolidated Financial Statements. In July 2018, the FASB issued ASU No. 2018-11, “Leases - Targeted Improvements” to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02 (January 1, 2019 for the Company). The Company adopted ASU 2018-11 on its required effective date of January 1, 2019 and elected both transition options mentioned above. ASU 2018-11 did not have a material impact on the Company’s Consolidated Financial Statements. In December 2018, the FASB issued ASU No. 2018-20, “Narrow-Scope Improvements for Lessors.” This ASU (1) allows lessors to make an accounting policy election of presenting sales taxes and other similar taxes collected from lessees on a net basis, (2) requires a lessor to exclude lessor costs paid directly by a lessee to third parties on the lessor’s behalf and include lessor costs that are paid by the lessor and reimbursed by the lessee in the measurement of variable lease revenue and the associated expense, and (3) clarifies that when lessors allocate variable payments to lease and non-lease components they are required to follow the recognition guidance in the new leases standard for the lease component and other applicable guidance, such as the new revenue standard, for the non-lease component. The Company adopted ASU 2018-20 on its required effective date of January 1, 2019 and elected to present sales taxes and other similar taxes collected from lessees on a net basis as described in (1) above. ASU 2018-20 did not have a material impact on the Company’s Consolidated Financial Statements. In March 2019, the FASB issued ASU No. 2019-01, “Leases: Codification Improvements.” This ASU (1) states that for lessors that are not manufacturers or dealers, the fair value of the underlying asset is its cost, less any volume or trade discounts, as long as there isn’t a significant amount of time between acquisition of the asset and lease commencement; (2) clarifies that lessors in the scope of ASC 942 (such as the Company) must classify principal payments received from sales-type and direct financing leases in investing activities in the statement of cash flows; and (3) clarifies the transition guidance related to certain interim disclosures provided in the year of adoption. To coincide with the adoption of ASU No. 2016-02, the Company elected to early adopt ASU 2019-01 on January 1, 2019. The adoption of this ASU did not have a material impact on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” With respect to Topic 815, Derivatives and Hedging, ASU 2019-04 clarifies that the reclassification of a debt security from held-to-maturity (“HTM”) to available-for-sale (“AFS”) under the transition guidance in ASU 2017-12 would not (1) call into question the classification of other HTM securities, (2) be required to actually designate any reclassified security in a last-of-layer hedge, or (3) be restricted from selling any reclassified security. As part of the transition of ASU 2019-04, entities may reclassify securities that would qualify for designation as the hedged item in a last-of-layer hedging relationship from HTM to AFS; however, entities that already made such a reclassification upon their adoption of ASU 2017-12 are precluded from reclassifying additional securities. The Company did not reclassify any securities from HTM to AFS upon adoption of ASU 2017-12. The Company elected to early adopt the amendments to Topic 815 in June 2019. See Note 3 Investment Securities for more information regarding the impact of the transfer of certain HTM debt securities to AFS. The amendments and pending adoption to Topics 326 and 825 are described in the section below. Accounting Standards Pending Adoption In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace today’s “incurred loss” approach with an “expected loss” approach known as current expected credit loss (“CECL”), which will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL approach will not apply to AFS debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the credit losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019 and the Company is planning to adopt the standard in the first quarter of 2020. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company is continuing its implementation efforts through its Company-wide implementation team. This team has assigned roles and responsibilities, key tasks to complete, and a general timeline to be followed. The team meets periodically to discuss the latest developments and ensure progress is being made. The team has been working with an advisory consultant and has finalized and documented the methodologies that will be utilized. The team is currently developing controls, processes, policies and disclosures in preparation for performing a full end to end parallel run. The Company’s preliminary evaluation indicates the provisions of ASU No. 2016-13 are expected to impact the Company’s Consolidated Financial Statements, in particular the level of the reserve for credit losses. The Company is continuing to evaluate the extent of the potential impact and expects that portfolio composition and economic conditions at the time of adoption will be a factor. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. As ASU No. 2018-13 only revises disclosure requirements, it will not have a material impact on the Company’s Consolidated Financial Statements. As mentioned in the previous section the FASB issued ASU No. 2019-04 in April 2019. With respect to Topic 326, Financial Instruments - Credit Losses, ASU 2019-04 clarifies the scope of the credit losses standard and addresses issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments, among other things. With respect to Topic 825, Financial Instruments, on recognizing and measuring financial instruments, ASU 2019-04 addresses the scope of the guidance, the requirement for remeasurement under ASC 820 when using the measurement alternative, certain disclosure requirements and which equity securities have to be remeasured at historical exchange rates. The amendments to Topic 326 have the same effective dates as ASU 2016-13 (i.e., the first quarter of 2020). The Company is currently evaluating the potential impact of Topic 326 amendments on the Company’s Consolidated Financial Statements. The amendments to Topic 825 are effective for interim and annual reporting periods beginning after December 15, 2019 and are not expected to have a material impact on the Company’s Consolidated Financial Statements. In May 2019, the FASB issued ASU No. 2019-05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019-05 has the same effective date as ASU 2016-13 (i.e., the first quarter of 2020). The Company does not expect to elect the fair value option, and therefore, ASU 2019-05 is not expected to impact the Company’s Consolidated Financial Statements.

In June 2019, the Company elected to early adopt the amendments to Topic 815, Derivatives and Hedging, which allowed the Company a one-time reclassification of certain prepayable debt securities from held-to-maturity to available-for-sale. On June 10, 2019, prepayable debt securities with a carrying value of $1.0 billion and a net unrealized gain of $3.1 million were transferred from held-to-maturity to available-for-sale. The reclassified securities consisted of mortgage-backed securities issued by U.S. government agencies and government-sponsored enterprises, municipal debt securities, and corporate debt securities. The table below presents an analysis of the contractual maturities of the Company’s investment securities as of June 30, 2019 .

Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. As of June 30, 2019 and December 31, 2018 , the gross unrealized losses reported for mortgage-backed securities were mostly related to investment securities issued by the Government National Mortgage Association. The Company does not intend to sell the investment securities that were in an unrealized loss position and it is not more likely than not that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity. Interest income from taxable and non-taxable investment securities for the three and six months ended June 30, 2019 and 2018 were as follows: Three Months Ended Six Months Ended (dollars in thousands) 2019 2018 2019 2018 Taxable $ 35,336 $ 28,405 $ 67,328 $ 57,076 Non-Taxable 1,885 4,686 5,246 9,452 Total Interest Income from Investment Securities $ 37,221 $ 33,091 $ 72,574 $ 66,528 As of June 30, 2019 , included in the Company’s investment securities portfolio were debt securities issued by political subdivisions within the State of Hawaii of $127.8 million , representing 99% of the total fair value of the Company’s municipal debt securities. Of the entire Hawaii municipal bond portfolio, 80% were credit-rated Aa2 or better by Moody’s. Most of the remaining Hawaii municipal bonds were credit-rated A1 or better by at least one nationally recognized statistical rating organization. Of the Company’s total Hawaii municipal bond holdings, 75% were general obligation issuances. As of June 30, 2019 and December 31, 2018 , the carrying value of the Company’s Federal Home Loan Bank of Des Moines stock and Federal Reserve Bank stock was as follows: (dollars in thousands) June 30, December 31, Federal Home Loan Bank Stock $ 14,000 $ 15,000 Federal Reserve Bank Stock 20,970 20,858 Total $ 34,970 $ 35,858 These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution. The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. Visa Class B Restricted Shares In 2008, the Company received Visa Class B restricted shares as part of Visa’s initial public offering. These shares are transferable only under limited circumstances until they can be converted into the publicly traded Class A common shares. This conversion will not occur until the settlement of certain litigation which will be indemnified by Visa members, including the Company. Visa funded an escrow account from its initial public offering to settle these litigation claims. Should this escrow account be insufficient to cover these litigation claims, Visa is entitled to fund additional amounts to the escrow account by reducing each member bank’s Class B conversion ratio to unrestricted Class A shares. As of June 30, 2019 , the conversion ratio was 1.6298 . See Note 12 Derivative Financial Instruments for more information. The Company occasionally sells these Visa Class B shares to other financial institutions. Concurrent with every sale the Company enters into an agreement with the buyer that requires payment to the buyer in the event Visa further reduces the conversion ratio. Based on the existing transfer restriction and the uncertainty of the outcome of the Visa litigation mentioned above, the remaining 83,014 Class B shares ( 135,296 Class A equivalents) that the Company owns as of June 30, 2019

The Company uses an internal credit risk rating system that categorizes loans and leases into pass, special mention, or classified categories. Credit risk ratings are applied individually to those classes of loans and leases that have significant or unique credit characteristics that benefit from a case-by-case evaluation. These are typically loans and leases to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans and leases that are underwritten and structured using standardized criteria and characteristics, such as statistical models (e.g., credit scoring or payment performance), are typically risk-rated and monitored collectively. These are typically loans and leases to individuals in the classes which comprise the consumer portfolio segment. The following are the definitions of the Company’s credit quality indicators: Pass: Loans and leases in all classes within the commercial and consumer portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan or lease agreement. Management believes that there is a low likelihood of loss related to those loans and leases that are considered Pass. Special Mention: Loans and leases that have potential weaknesses that deserve management’s close attention. If not addressed, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease. Management believes that there is a moderate likelihood of some loss related to those loans and leases that are considered Special Mention. Classified: Loans and leases in the classes within the commercial portfolio segment that are inadequately protected by the sound worth and paying capacity of the borrower or of the collateral pledged, if any. Classified loans and leases are also those in the classes within the consumer portfolio segment that are past due 90 days or more as to principal or interest. Residential mortgage loans that are past due 90 days or more as to principal or interest may be considered Pass if the Company is in the process of collection and the current loan-to-value ratio is 60% or less. Home equity loans that are past due 90 days or more as to principal or interest may be considered Pass if the Company is in the process of collection, the first mortgage is with the Company, and the current combined loan-to-value ratio is 60% or less. Residential mortgage and home equity loans may be current as to principal and interest, but may be considered Classified for a period of generally up to six months following a loan modification. Following a period of demonstrated performance in accordance with the modified contractual terms, the loan may be removed from Classified status. Management believes that there is a distinct possibility that the Company will sustain some loss if the deficiencies related to Classified loans and leases are not corrected in a timely manner. The Company’s credit quality indicators are periodically updated on a case-by-case basis. The following presents by class and by credit quality indicator, the recorded investment in the Company’s loans and leases as of June 30, 2019 and December 31, 2018 .

For the three and six months ended June 30, 2019 and 2018 , the amounts of interest income recognized by the Company within the periods that the loans were impaired were primarily related to loans modified in a troubled debt restructuring (“TDR”) that remained on accrual status. For the three and six months ended June 30, 2019 and 2018 , the amount of interest income recognized using a cash-basis method of accounting during the periods that the loans were impaired was not material. Modifications A modification of a loan constitutes a TDR when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. Loans modified in a TDR were $56.7 million and $54.0 million as of June 30, 2019 and December 31, 2018 , respectively. There were $0.3 million and $0.2 million commitments to lend additional funds on loans modified in a TDR as of June 30, 2019 and December 31, 2018 , respectively. The Company offers various types of concessions when modifying a loan or lease. Commercial and industrial loans modified in a TDR often involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans. Additional collateral, a co-borrower, or a guarantor is often requested. Commercial mortgage and construction loans modified in a TDR often 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 co-borrower or guarantor. Construction loans modified in a TDR may also involve extending the interest-only payment period. Residential mortgage loans modified in a TDR generally include a lower interest rate and the loan being fully amortized for up to 40 years from the modification effective date. In some cases, the Company may forbear a portion of the unpaid principal balance with a balloon payment due upon maturity or pay-off of the loan. Land loans are also included in the class of residential mortgage loans. Land loans are typically structured as interest-only monthly payments with a balloon payment due at maturity. Land loan modifications usually involve extending the interest-only monthly payments up to an additional five years with a balloon payment due at maturity, or re-amortizing the remaining balance over a period up to 360 months . Interest rates are not changed for land loan modifications. Home equity modifications are made infrequently and uniquely designed to meet the specific needs of each borrower. Automobile loans modified in a TDR are primarily comprised of loans where the Company has lowered monthly payments by extending the term. Loans modified in a TDR are typically already on non-accrual status and partial charge-offs have in some cases already been taken against the outstanding loan balance. As a result, loans modified in a TDR may have the financial effect of increasing the specific Allowance associated with the loan. An Allowance for impaired commercial and consumer 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.

Commercial and consumer loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a TDR subsequently default, the Company evaluates the loan for possible further impairment. The specific Allowance associated with the loan may be increased, adjustments may be made in the allocation of the Allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan. Foreclosure Proceedings Consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure totaled $2.7 million as of June 30, 2019 .

Mortgage Servicing Rights

Mortgage Servicing Rights	6 Months Ended
	Jun. 30, 2019
Transfers and Servicing of Financial Assets [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights The Company’s portfolio of residential mortgage loans serviced for third parties was $3.0 billion and $2.9 billion as of June 30, 2019 and December 31, 2018 , respectively. Substantially all of these loans were originated by the Company and sold to third parties on a non-recourse basis with servicing rights retained. These retained servicing rights are recorded as a servicing asset and are initially recorded at fair value (see Note 14 Fair Value of Assets and Liabilities for more information). Changes to the balance of mortgage servicing rights are recorded in mortgage banking income in the Company’s consolidated statements of income. The Company’s mortgage servicing activities include collecting principal, interest, and escrow payments from borrowers; making tax and insurance payments on behalf of borrowers; monitoring delinquencies and executing foreclosure proceedings; and accounting for and remitting principal and interest payments to investors. Servicing income, including late and ancillary fees, was $1.8 million for the three months ended June 30, 2019 and 2018 , and $3.6 million for the six months ended June 30, 2019 and 2018 . Servicing income is recorded in mortgage banking income in the Company’s consolidated statements of income. The Company’s residential mortgage investor loan servicing portfolio is primarily comprised of fixed rate loans concentrated in Hawaii. For the three and six months ended June 30, 2019 and 2018 , the change in the carrying value of the Company’s mortgage servicing rights accounted for under the fair value measurement method was as follows: Three Months Ended Six Months Ended (dollars in thousands) 2019 2018 2019 2018 Balance at Beginning of Period $ 1,268 $ 1,404 $ 1,290 $ 1,454 Change in Fair Value: Due to Payoffs (56 ) (38 ) (78 ) (88 ) Total Changes in Fair Value of Mortgage Servicing Rights (56 ) (38 ) (78 ) (88 ) Balance at End of Period $ 1,212 $ 1,366 $ 1,212 $ 1,366 For the three and six months ended June 30, 2019 and 2018 , the change in the carrying value of the Company’s mortgage servicing rights accounted for under the amortization method was as follows: Three Months Ended Six Months Ended (dollars in thousands) 2019 2018 2019 2018 Balance at Beginning of Period $ 22,881 $ 23,089 $ 23,020 $ 23,168 Servicing Rights that Resulted From Asset Transfers 974 775 1,524 1,396 Amortization (824 ) (647 ) (1,513 ) (1,347 ) Valuation Allowance Provision (10 ) — (10 ) — Balance at End of Period $ 23,021 $ 23,217 $ 23,021 $ 23,217 Valuation Allowance: Balance at Beginning of Period $ — $ — $ — $ — Valuation Allowance Provision (10 ) — (10 ) — Balance at End of Period $ (10 ) $ — $ (10 ) $ — Fair Value of Mortgage Servicing Rights Accounted for Under the Amortization Method Beginning of Period $ 26,814 $ 28,600 $ 29,218 $ 26,716 End of Period $ 24,905 $ 29,746 $ 24,905 $ 29,746 The key data and assumptions used in estimating the fair value of the Company’s mortgage servicing rights as of June 30, 2019 and December 31, 2018 were as follows: June 30, December 31, 2018 Weighted-Average Constant Prepayment Rate 1 10.39 % 7.01 % Weighted-Average Life (in years) 6.33 7.89 Weighted-Average Note Rate 4.06 % 4.06 % Weighted-Average Discount Rate 2 7.49 % 9.59 % 1 Represents annualized loan prepayment rate assumption. 2 Derived from multiple interest rate scenarios that incorporate a spread to a market yield curve and market volatilities. A sensitivity analysis of the Company’s fair value of mortgage servicing rights to changes in certain key assumptions as of June 30, 2019 and December 31, 2018 is presented in the following table. (dollars in thousands) June 30, December 31, Constant Prepayment Rate Decrease in fair value from 25 basis points (“bps”) adverse change $ (292 ) $ (361 ) Decrease in fair value from 50 bps adverse change (577 ) (716 ) Discount Rate Decrease in fair value from 25 bps adverse change (253 ) (325 ) Decrease in fair value from 50 bps adverse change (502 ) (643 ) This analysis generally cannot be extrapolated because the relationship of a change in one key assumption to the change in the fair value of the Company’s mortgage servicing rights usually is not linear. Also, the effect of changing one key assumption without changing other assumptions is not realistic.

Low Income Housing Tax Credit P

Low Income Housing Tax Credit Partnerships	6 Months Ended

Equity Method Investments and Joint Ventures [Abstract]
Low Income Housing Tax Credit Partnerships	Affordable Housing Projects Tax Credit Partnerships The Company makes equity investments in various limited partnerships that sponsor affordable housing projects utilizing the Low Income Housing Tax Credit (“LIHTC”) pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to achieve a satisfactory return on capital, to facilitate the sale of affordable housing product offerings, and to assist in achieving goals associated with the Community Reinvestment Act. The primary activities of the limited partnerships include the identification, development, and operation of multi-family housing that is leased to qualifying residential tenants. Generally, these types of investments are funded through a combination of debt and equity. The Company is a limited partner in each LIHTC limited partnership. Each limited partnership is managed by an unrelated third party general partner who exercises significant control over the affairs of the limited partnership. The general partner has all the rights, powers and authority granted or permitted to be granted to a general partner of a limited partnership. Duties entrusted to the general partner of each limited partnership include, but are not limited to: investment in operating companies, company expenditures, investment of excess funds, borrowing funds, employment of agents, disposition of fund property, prepayment and refinancing of liabilities, votes and consents, contract authority, disbursement of funds, accounting methods, tax elections, bank accounts, insurance, litigation, cash reserve, and use of working capital reserve funds. Except for limited rights granted to the limited partner(s) relating to the approval of certain transactions, the limited partner(s) may not participate in the operation, management, or control of the limited partnership’s business, transact any business in the limited partnership’s name or have any power to sign documents for or otherwise bind the limited partnership. In addition, the general partner may only be removed by the limited partner(s) in the event the general partner fails to comply with the terms of the agreement or is negligent in performing its duties. The general partner of each limited partnership has both the power to direct the activities which most significantly affect the performance of each partnership and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. Therefore, the Company has determined that it is not the primary beneficiary of any LIHTC partnership. The Company uses the effective yield method to account for its pre-2015 investments in these entities. Beginning January 1, 2015, any new investments that meet the requirements of the proportional amortization method are recognized using the proportional amortization method. The Company’s net affordable housing tax credit investments and related unfunded commitments were $68.6 million and $73.7 million as of June 30, 2019 and December 31, 2018 , respectively, and are included in other assets in the consolidated statements of condition. Unfunded Commitments As of June 30, 2019 , the expected payments for unfunded affordable housing commitments were as follows: (dollars in thousands) Amount 2019 $ 3,050 2020 8,317 2021 42 2022 49 2023 42 Thereafter 1,281 Total Unfunded Commitments $ 12,781 The following table presents tax credits and other tax benefits recognized and amortization expense related to affordable housing for the three and six months ended June 30, 2019 and 2018 .

During the first quarter of 2018, the Company recorded a $2.0 million adjustment to increase its LIHTC investments. This adjustment resulted in a decrease to the provision for income tax.

Balance Sheet Offsetting

Balance Sheet Offsetting	6 Months Ended

Offsetting [Abstract]
Balance Sheet Offsetting	Balance Sheet Offsetting Interest Rate Swap Agreements (“Swap Agreements”) The Company enters into swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting swap agreements with highly-rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated statements of condition (asset positions are included in other assets and liability positions are included in other liabilities). The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of cash or marketable securities, is posted by the party (i.e., the Company or the financial institution counterparty) with net liability positions in accordance with contract thresholds. The Company had net liability positions with its financial institution counterparties totaling $5.8 million and $0.3 million as of June 30, 2019 and December 31, 2018 , respectively. See Note 12 Derivative Financial Instruments for more information. Parties to a centrally cleared over-the-counter derivative exchange daily payments that reflect the daily change in value of the derivative. Effective 2017, these payments, commonly referred to as variation margin, are recorded as settlements of the derivatives’ mark-to-market exposure rather than collateral against the exposures. This rule change effectively results in any centrally cleared derivative having a fair value that approximates zero on a daily basis, and therefore, these swap agreements were not included in the offsetting table at the end of this section. See Note 12 Derivative Financial Instruments for more information. Securities Sold Under Agreements to Repurchase (“Repurchase Agreements”) The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, these repurchase agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as sales and subsequent repurchases of securities. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated statements of condition, while the securities underlying the repurchase agreements remain in the respective investment securities asset accounts. As a result, there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities. In addition, as the Company does not enter into reverse repurchase agreements, there is no such offsetting to be done with the repurchase agreements. 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 (e.g., fail to make an interest payment to the counterparty). For private institution repurchase agreements, if the private institution counterparty were to default (e.g., declare bankruptcy), the Company could cancel the repurchase agreement (i.e., cease payment of principal and interest) and attempt collection on the amount of collateral value in excess of the repurchase agreement fair value. The collateral is held by a third party financial institution in the counterparty’s custodial account. The counterparty has the right to sell or repledge the investment securities. For government entity repurchase agreements, the collateral is held by the Company in a segregated custodial account under a tri-party agreement. 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 securities. The Company closely monitors collateral levels to ensure adequate levels are maintained, while mitigating the potential risk of over-collateralization in the event of counterparty default. The following table presents the remaining contractual maturities of the Company’s repurchase agreements as of June 30, 2019 and December 31, 2018 , disaggregated by the class of collateral pledged.

For repurchase agreements with government entities, the fair value of investment securities pledged was $5.2 million and $6.8 million as of June 30, 2019 and December 31, 2018

Business Segments

Segment Reporting [Abstract]
Business Segments	Business Segments The Company’s business segments are defined as Retail Banking, Commercial Banking, Investment Services and Private Banking, and Treasury and Other. The Company’s internal management accounting process measures the performance of these business segments. This process, which is not necessarily comparable with the process used by any other financial institution, uses various techniques to assign balance sheet and income statement amounts to the business segments, including allocations of income, expense, the provision for credit losses, and capital. This process is dynamic and requires certain allocations based on judgment and other subjective factors. Unlike financial accounting, there is no comprehensive authoritative guidance for management accounting that is equivalent to GAAP. Previously reported results have been reclassified to conform to the current reporting structure. The net interest income of the business segments reflects the results of a funds transfer pricing process that matches assets and liabilities with similar interest rate sensitivity and maturity characteristics and reflects the allocation of net interest income related to the Company’s overall asset and liability management activities on a proportionate basis. The basis for the allocation of net interest income is a function of the Company’s assumptions that are subject to change based on changes in current interest rates and market conditions. Funds transfer pricing also serves to transfer interest rate risk to Treasury. However, the other business segments have some latitude to retain certain interest rate exposures related to customer pricing decisions within guidelines. The provision for credit losses reflects the actual net charge-offs of the business segments. The amount of the consolidated provision for loan and lease losses is based on the methodology that we use to estimate the Company’s consolidated Allowance. The residual provision for credit losses to arrive at the consolidated provision for credit losses is included in Treasury and Other. Noninterest income and expense includes allocations from support units to business units. These allocations are based on actual usage where practicably calculated or by management’s estimate of such usage. The provision for income taxes is allocated to business segments using a 26% effective income tax rate. However, the provision for income taxes for the Company’s Leasing business unit (included in the Commercial Banking segment) and Auto Leasing portfolio and Pacific Century Life Insurance business unit (both included in the Retail Banking segment) are assigned their actual effective income tax rates due to the unique relationship that income taxes have with their products. The residual income tax expense or benefit to arrive at the consolidated effective income tax rate is included in Treasury and Other. Retail Banking Retail Banking offers a broad range of financial products and services to consumers and small businesses. Loan and lease products include residential 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 include checking, savings, and time deposit accounts. Retail Banking also offers co-branded credit cards and some types of consumer insurance products. Products and services from Retail Banking are delivered to customers through 68 branch locations and 383 ATMs throughout Hawaii and the Pacific Islands, e-Bankoh (on-line banking service), a 24-hour customer service center, and a mobile banking service. Commercial Banking Commercial Banking offers products including corporate banking, commercial real estate loans, commercial lease financing, auto dealer financing, and deposit products. Commercial lending and deposit products are offered to middle-market and large companies in Hawaii and the Pacific Islands. In addition, Commercial Banking offers deposit products to government entities in Hawaii. Commercial real estate mortgages focus on customers that include investors, developers, and builders predominantly domiciled in Hawaii. Commercial Banking also includes international banking and provides merchant services to its customers. Investment Services and Private Banking Investment Services and Private Banking includes private banking and international client banking services, trust services, investment management, and institutional investment advisory services. A significant portion of this segment’s income is derived from fees, which are generally based on the market values of assets under management. The private banking and personal trust groups assist individuals and families in building and preserving their wealth by providing investment, credit, and trust services to high-net-worth individuals. The investment management group manages portfolios utilizing a variety of investment products. Institutional client services offer investment advice to corporations, government entities, and foundations. This segment also provides a full service brokerage offering equities, mutual funds, life insurance, and annuity products. Treasury and Other Treasury consists of corporate asset and liability management activities, including interest rate risk management and a foreign currency exchange business. This segment’s assets and liabilities (and related interest income and expense) consist of interest-bearing deposits, investment securities, federal funds sold and purchased, and short and long-term borrowings. The primary sources of noninterest income are from bank-owned life insurance, net gains from the sale of investment securities, and foreign exchange income related to customer-driven currency requests from merchants and island visitors. The net residual effect of the transfer pricing of assets and liabilities is included in Treasury, along with the elimination of intercompany transactions. Other organizational units (Technology, Operations, Marketing, Human Resources, Finance, Credit and Risk Management, and Corporate and Regulatory Administration) provide a wide-range of support to the Company’s other income earning segments. Expenses incurred by these support units are charged to the business segments through an internal cost allocation process.

As with any financial instrument, derivative financial instruments have inherent risks. Market risk is defined as the risk of adverse financial impact due to fluctuations in interest rates, foreign exchange rates, and equity prices. Market risks associated with derivative financial instruments are balanced with the expected returns to enhance earnings performance and shareholder value, while limiting the volatility of each. The Company uses various processes to monitor its overall market risk exposure, including sensitivity analysis, value-at-risk calculations, and other methodologies. Derivative financial instruments are also subject to credit and counterparty risk, which is defined as the risk of financial loss if a borrower or counterparty is either unable or unwilling to repay borrowings or settle transactions in accordance with the underlying contractual terms. Credit and counterparty risks associated with derivative financial instruments are similar to those relating to traditional financial instruments. The Company manages derivative credit and counterparty risk by evaluating the creditworthiness of each borrower or counterparty, adhering to the same credit approval process used for commercial lending activities. As of June 30, 2019 and December 31, 2018 , the Company did not designate any derivative financial instruments as formal hedging relationships. The Company’s free-standing derivative financial instruments are required to be carried at their fair value on the Company’s consolidated statements of condition. These financial instruments have been limited to interest rate lock commitments (“IRLCs”), forward commitments, Swap Agreements, foreign exchange contracts, and conversion rate swap agreements. The Company enters into IRLCs for residential mortgage loans which commit us to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. To mitigate this risk, the Company utilizes forward commitments as economic hedges against the potential decreases in the values of the loans held for sale. IRLCs and forward commitments are free-standing derivatives which are carried at fair value with changes recorded in the mortgage banking component of noninterest income in the Company’s consolidated statements of income. The Company enters into Swap Agreements to facilitate the risk management strategies of a small number of commercial banking customers. The Company mitigates the interest rate risk of entering into these agreements by entering into equal and offsetting interest rate swap agreements with highly rated third party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated statements of condition. Fair value changes are recorded in other noninterest income in the Company’s consolidated statements of income. 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. Collateral, usually in the form of cash or marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds. See Note 7 Balance Sheet Offsetting for more information. The Company’s interest rate swap agreements with financial institution counterparties may contain credit-risk-related contingent features tied to a specified credit rating of the Company. Under these provisions, should the Company’s specified rating fall below a particular level (e.g., investment grade), or if the Company no longer obtains the specified rating, the counterparty may require the Company to pledge collateral on an immediate and ongoing basis (subject to the requirement that such swaps are in a net liability position beyond the level specified in the contract), or require immediate settlement of the swap agreement. Other credit-risk-related contingent features may also allow the counterparty to require immediate settlement of the swap agreement if the Company fails to maintain a specified minimum level of capitalization. With regard to derivative contracts not centrally cleared through a clearinghouse, regulations require collateral to be posted by the party with a net liability position (i.e., the threshold for posting collateral was reduced to zero, subject to certain minimum transfer amounts). The requirements generally applied to new derivative contracts entered into by the Company after March 1, 2017, although certain counterparties may elect to apply lower thresholds to existing contracts. Parties to a centrally cleared over-the-counter derivative exchange daily payments that reflect the daily change in value of the derivative. These payments are commonly referred to as variation margin. Historically, variation margin payments have typically been treated as collateral against the derivative position. Effective 2017, the Chicago Mercantile Exchange and LCH.Clearnet Limited (collectively, the “clearinghouses”) amended their rulebooks to legally characterize variation margin payments for over-the-counter derivatives they clear as settlements of the derivatives’ mark-to-market exposure rather than collateral against the exposures. This rule change effectively causes any derivative cleared through one of the clearinghouses to have a fair value that approximates zero on a daily basis. The majority of the Company’s swap agreements executed with third party financial institutions are now required to be cleared through one of the clearinghouses. The uncleared swap agreements executed with third party financial institutions will remain subject to the collateral requirements and credit-risk-related contingent features described in the previous paragraphs, and therefore, are not subject to the variation margin rule change. Likewise, the swap agreements executed with the Company’s commercial banking customers will remain uncleared and will also not be subject to the variation margin rule change. The Company utilizes foreign exchange contracts to offset risks related to transactions executed on behalf of customers. The foreign exchange contracts are free-standing derivatives which are carried at fair value with changes included in other noninterest income in the Company’s consolidated statements of income. As each sale of Visa Class B restricted shares was completed, the Company entered into a conversion rate swap agreement with the buyer that requires payment to the buyer in the event Visa further reduces the conversion ratio of Class B into Class A unrestricted common shares. In the event of Visa increasing the conversion ratio, the buyer would be required to make payment to the Company. As of June 30, 2019 , the conversion rate swap agreement was valued at zero (i.e., no contingent liability recorded) as further reductions to the conversion ratio were deemed neither probable nor reasonably estimable by management. However, in June 2018, Visa announced a reduction of the conversion ratio from 1.6483 to 1.6298 effective June 28, 2018. As a result, the Company recorded a $1.0 million liability in June 2018 which represents the amount due to the buyers of the Visa Class B shares in July 2018.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, and Guarantees	Commitments, Contingencies, and Guarantees The Company’s credit commitments as of June 30, 2019 and December 31, 2018 were as follows: (dollars in thousands) June 30, December 31, Unfunded Commitments to Extend Credit $ 2,701,892 $ 2,646,085 Standby Letters of Credit 61,923 62,344 Commercial Letters of Credit 14,893 9,411 Total Credit Commitments $ 2,778,708 $ 2,717,840 Unfunded Commitments to Extend Credit Commitments to extend credit are agreements to lend to a customer as long as there is no violation of the terms or conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since commitments may expire without being drawn, the total commitment amount does not necessarily represent future cash requirements. Standby and Commercial Letters of Credit Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally become payable upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and a third party. The contractual amount of these letters of credit represents the maximum potential future payments guaranteed by the Company. The Company has recourse against the customer for any amount it is required to pay to a third party under a standby letter of credit, and generally holds cash or deposits as collateral on those standby letters of credit for which collateral is deemed necessary. Contingencies On September 9, 2016, a purported class action lawsuit was filed by a Bank customer primarily alleging Bank of Hawaii’s practice of determining whether consumer deposit accounts were overdrawn based on “available balance” (which deducts debit card transactions that have taken place but which have not yet been posted) was not properly applied or disclosed to customers. Additionally, on January 20, 2017, another purported class action lawsuit was filed by a Bank customer alleging Bank of Hawaii’s practice of assessing continuous negative balance overdraft fees on accounts remaining in a negative balance for extended periods of time beyond the date of the initial overdraft constituted a usurious interest charge and a breach of contract with the customer. This lawsuit was resolved by way of settlement for an amount that was not material. These lawsuits are similar to lawsuits filed against other financial institutions pertaining to available balance overdraft fee disclosures and continuing negative balance overdraft fees. The outcome of the first lawsuit remains uncertain at this time. Management disputes any wrongdoing and the case is being vigorously defended. In addition to the litigation noted above, the Company is subject to various other pending and threatened legal proceedings arising out of the normal course of business or operations. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal proceedings using the most recent information available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. Based on information currently available, management believes that the eventual outcome of these claims against the Company will not be materially in excess of such amounts reserved by the Company. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters may result in a loss that materially exceeds the reserves established by the Company. Risks Related to Representation and Warranty Provisions The Company sells residential mortgage loans in the secondary market primarily to the Federal National Mortgage Association (“Fannie Mae”). The Company also pools Federal Housing Administration (“FHA”) insured and U.S. Department of Veterans Affairs (“VA”) guaranteed residential mortgage loans for sale to the Government National Mortgage Corporation (“Ginnie Mae”). These pools of FHA-insured and VA-guaranteed residential mortgage loans are securitized by Ginnie Mae. The agreements under which the Company sells residential mortgage loans to Fannie Mae or Ginnie Mae and the insurance or guaranty agreements with FHA and VA contain provisions that include various representations and warranties regarding the origination and characteristics of the residential mortgage loans. Although the specific representations and warranties vary among investors, insurance or guarantee agreements, they typically cover ownership of the loan, validity of the lien securing the loan, the absence of delinquent taxes or liens against the property securing the loan, compliance with loan criteria set forth in the applicable agreement, compliance with applicable federal, state, and local laws, and other matters. As of June 30, 2019 , the unpaid principal balance of residential mortgage loans sold by the Company was $2.7 billion . The agreements under which the Company sells residential mortgage loans require delivery of various documents to the investor or its document custodian. Although these loans are primarily sold on a non-recourse basis, the Company may be obligated to repurchase residential mortgage loans or reimburse investors for losses incurred if a loan review reveals that underwriting and documentation standards were potentially not met. Some agreements may require the Company to repurchase delinquent loans. Upon receipt of a repurchase request, the Company works with investors or insurers to arrive at a mutually agreeable resolution. Repurchase demands are typically reviewed on an individual loan-by-loan basis to validate the claims made by the investor or insurer and to determine if a contractually required repurchase event has occurred. The Company manages the risk associated with potential repurchases or other forms of settlement through its underwriting and quality assurance practices and by servicing mortgage loans to meet investor and secondary market standards. During the six months ended June 30, 2019 , there was one residential mortgage loan repurchased with an aggregate unpaid principal balance of $0.4 million as a result of the representation and warranty provisions contained in the applicable contract. The one loan was delinquent in payment of principal and interest at the time of repurchase, however no material loss was incurred related to this repurchase. As of June 30, 2019 , there were no pending repurchase requests related to representation and warranty provisions. Risks Relating to Residential Mortgage Loan Servicing Activities In addition to servicing loans in the Company’s portfolio, substantially all of the loans the Company sells to investors are sold with servicing rights retained. The Company also services loans originated by other mortgage loan originators. As servicer, the Company’s primary duties are to: (1) collect payments due from borrowers; (2) advance certain delinquent payments of principal and interest; (3) maintain and administer any hazard, title, or primary mortgage insurance policies relating to the mortgage loans; (4) maintain any required escrow accounts for payment of taxes and insurance and administer escrow payments; and (5) foreclose on defaulted mortgage loans or, to the extent consistent with the documents governing a securitization, consider alternatives to foreclosure, such as loan modifications or short sales. Each agreement under which the Company acts as servicer generally specifies a standard of responsibility for actions taken by the Company in such capacity and provides protection against expenses and liabilities incurred by the Company when acting in compliance with the respective servicing agreements. However, if the Company commits a material breach of obligations as servicer, the Company may be subject to termination if the breach is not cured within a specified period following notice. The standards governing servicing and the possible remedies for violations of such standards vary by investor. These standards and remedies are determined by servicing guides issued by the investors as well as the contract provisions established between the investors and the Company. Remedies could include repurchase of an affected loan. For the six months ended June 30, 2019 , there were no loans repurchased related to loan servicing activities. As of June 30, 2019 , there were no pending repurchase requests related to loan servicing activities. Although to date repurchase requests related to representation and warranty provisions and servicing activities have been limited, it is possible that requests to repurchase mortgage loans may increase in frequency as investors more aggressively pursue all means of recovering losses on their purchased loans. However, as of June 30, 2019 , management believes that this exposure is not material due to the historical level of repurchase requests and loss trends and thus has not established a liability for losses related to mortgage loan repurchases. As of June 30, 2019 , 99% of the Company’s residential mortgage loans serviced for investors were current. The Company maintains ongoing communications with investors and continues to evaluate this exposure by monitoring the level and number of repurchase requests as well as the delinquency rates in the loans sold to investors.

Fair Value of Assets and Liabil

Fair Value of Assets and Liabilities	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Fair Value of Assets and Liabilities Fair Value Hierarchy Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP established a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels: Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and is used to measure fair value whenever available. A contractually binding sales price also provides reliable evidence of fair value. Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that utilize model-based techniques for which all significant assumptions are observable in the market. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement; inputs to the valuation methodology that utilize model-based techniques for which significant assumptions are not observable in the market; or inputs to the valuation methodology that require significant management judgment or estimation, some of which may be internally developed. In some instances, an instrument may fall into multiple levels of the fair value hierarchy. In such instances, the instrument’s level within the fair value hierarchy is based on the lowest of the three levels (with Level 3 being the lowest) that is significant to the fair value measurement. Our assessment of the significance of an input requires judgment and considers factors specific to the instrument. Assets and Liabilities Measured at Fair Value on a Recurring Basis Investment Securities Available-for-Sale Fair values of investment securities available-for-sale were primarily measured using information from a third-party pricing service. This service provides pricing information by utilizing evaluated pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data from market research publications. Level 1 investment securities are comprised of debt securities issued by the U.S. Treasury, as quoted prices were available, unadjusted, for identical securities in active markets. Level 2 investment securities were primarily comprised of debt securities issued by the Small Business Administration, states and municipalities, corporations, as well as mortgage-backed securities issued by government agencies and government-sponsored enterprises. Fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models. In cases where there may be limited or less transparent information provided by the Company’s third-party pricing service, fair value may be estimated by the use of secondary pricing services or through the use of non-binding third-party broker quotes. On a quarterly basis, management reviews the pricing information received from the Company’s third-party pricing service. This review process includes a comparison to a second source. The Company’s third-party pricing service has also established processes for us to submit inquiries regarding quoted prices. Periodically, based on these reviews, the Company will challenge the quoted prices provided by the Company’s 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 us. The Company’s third-party pricing service may then affirm the original quoted price or may update the evaluation on a going-forward basis. Generally, we do not adjust the price from the third-party service provider. On a quarterly basis, management also reviews a sample of securities priced by the Company’s third-party pricing service to review the significant assumptions and valuation methodologies used by the service. The information provided is comprised of market reference data, which may include reported trades; bids, offers, or broker-dealer dealer quotes; benchmark yields and spreads; as well as other reference data as appropriate. Based on this review, management determines whether the current placement of the security in the fair value hierarchy is appropriate or whether transfers may be warranted. Loans Held for Sale The fair value of the Company’s residential mortgage loans held for sale was determined based on quoted prices for similar loans in active markets, and therefore, is classified as a Level 2 measurement. Mortgage Servicing Rights Mortgage servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of mortgage servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The Company stratifies its mortgage servicing portfolio on the basis of loan type. The assumptions used in the discounted cash flow model are those that the Company believes market participants would use in estimating future net servicing income. Significant assumptions in the valuation of mortgage servicing rights include estimated loan repayment rates, the discount rate, servicing costs, and the timing of cash flows, among other factors. Mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other Assets Other assets recorded at fair value on a recurring basis are primarily comprised of investments related to deferred compensation arrangements. Quoted prices for these investments, primarily in mutual funds, are available in active markets. Thus, the Company’s investments related to deferred compensation arrangements are classified as Level 1 measurements in the fair value hierarchy. Derivative Financial Instruments Derivative financial instruments recorded at fair value on a recurring basis are comprised of IRLCs, forward commitments, interest rate swap agreements, foreign exchange contracts, and Visa Class B to Class A shares conversion rate swap agreements. The fair values of IRLCs are calculated based on the value of the underlying loan held for sale, which in turn is based on quoted prices for similar loans in the secondary market. However, this value is adjusted by a factor which considers the likelihood that the loan in a locked position will ultimately close. This factor, the closing ratio, is derived from the Bank’s internal data and is adjusted using significant management judgment. As such, IRLCs are classified as Level 3 measurements. Forward commitments are classified as Level 2 measurements as they are primarily based on quoted prices from the secondary market based on the settlement date of the contracts, interpolated or extrapolated, if necessary, to estimate a fair value as of the end of the reporting period. The fair values of interest rate swap agreements are calculated using a discounted cash flow approach and utilize Level 2 observable inputs such as a market yield curve, effective date, maturity date, notional amount, and stated interest rate. In addition, the Company includes in its fair value calculation a credit factor adjustment which is based primarily on management judgment. Thus, interest rate swap agreements are classified as a Level 3 measurement. The fair values of foreign exchange contracts are calculated using the Bank’s multi-currency accounting system which utilizes contract specific information such as currency, maturity date, contractual amount, and strike price, along with market data information such as the spot rates of specific currency and yield curves. Foreign exchange contracts are classified as Level 2 measurements because while they are valued using the Bank’s multi-currency accounting system, significant management judgment or estimation is not required. The fair value of the Visa Class B restricted shares to Class A unrestricted common shares conversion rate swap agreements represent the amount owed by the Company to the buyer of the Visa Class B shares as a result of a reduction of the conversion ratio subsequent to the sales date. As of June 30, 2019 and December 31, 2018 , the conversion rate swap agreements were valued at zero as reductions to the conversion ratio were neither probable nor reasonably estimable by management. See Note 12 Derivative Financial Instruments for more information. The Company is exposed to credit risk if borrowers or counterparties fail to perform. The Company seeks to minimize credit risk through credit approvals, limits, monitoring procedures, and collateral requirements. The Company generally enters into transactions with borrowers and counterparties that carry high quality credit ratings. Credit risk associated with borrowers or counterparties as well as the Company’s non-performance risk is factored into the determination of the fair value of derivative financial instruments. The table below presents the balances of assets and liabilities measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 : Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total June 30, 2019 Assets: Investment Securities Available-for-Sale Debt Securities Issued by the U.S. Treasury and Government Agencies $ 1,004 $ 334,528 $ — $ 335,532 Debt Securities Issued by States and Political Subdivisions — 62,219 — 62,219 Debt Securities Issued by U.S. Government-Sponsored Enterprises — 196 — 196 Debt Securities Issued by Corporations — 349,812 — 349,812 Mortgage-Backed Securities: Residential - Government Agencies — 1,227,930 — 1,227,930 Residential - U.S. Government-Sponsored Enterprises — 503,057 — 503,057 Commercial - Government Agencies — 171,203 — 171,203 Total Mortgage-Backed Securities — 1,902,190 — 1,902,190 Total Investment Securities Available-for-Sale 1,004 2,648,945 — 2,649,949 Loans Held for Sale — 22,706 — 22,706 Mortgage Servicing Rights — — 1,212 1,212 Other Assets 36,941 — — 36,941 Derivatives 1 — 498 27,371 27,869 Total Assets Measured at Fair Value on a $ 37,945 $ 2,672,149 $ 28,583 $ 2,738,677 Liabilities: Derivatives 1 $ — $ 877 $ 7,415 $ 8,292 Total Liabilities Measured at Fair Value on a $ — $ 877 $ 7,415 $ 8,292 December 31, 2018 Assets: Investment Securities Available-for-Sale Debt Securities Issued by the U.S. Treasury and Government Agencies $ 972 $ 391,429 $ — $ 392,401 Debt Securities Issued by States and Political Subdivisions — 563,996 — 563,996 Debt Securities Issued by U.S. Government-Sponsored Enterprises — 56 — 56 Debt Securities Issued by Corporations — 223,140 — 223,140 Mortgage-Backed Securities: Residential - Government Agencies — 190,442 — 190,442 Residential - U.S. Government-Sponsored Enterprises — 578,527 — 578,527 Commercial - Government Agencies — 59,380 — 59,380 Total Mortgage-Backed Securities — 828,349 — 828,349 Total Investment Securities Available-for-Sale 972 2,006,970 — 2,007,942 Loans Held for Sale — 10,987 — 10,987 Mortgage Servicing Rights — — 1,290 1,290 Other Assets 31,871 — — 31,871 Derivatives 1 — 812 13,792 14,604 Total Assets Measured at Fair Value on a $ 32,843 $ 2,018,769 $ 15,082 $ 2,066,694 Liabilities: Derivatives 1 $ — $ 371 $ 9,376 $ 9,747 Total Liabilities Measured at Fair Value on a $ — $ 371 $ 9,376 $ 9,747 1 The fair value of each class of derivatives is shown in Note 12 Derivative Financial Instruments . For the three and six months ended June 30, 2019 and 2018 , the changes in Level 3 assets and liabilities measured at fair value on a recurring basis were as follows: (dollars in thousands) Mortgage Servicing Rights 1 Net Derivative Assets and Liabilities 2 Three Months Ended June 30, 2019 Balance as of April 1, 2019 $ 1,268 $ 9,175 Realized and Unrealized Net Gains (Losses): Included in Net Income (56 ) 3,530 Transfers to Loans Held for Sale — (2,517 ) Variation Margin Payments — 9,768 Balance as of June 30, 2019 $ 1,212 $ 19,956 Total Unrealized Net Gains (Losses) Included in Net Income $ — $ 19,956 Three Months Ended June 30, 2018 Balance as of April 1, 2018 $ 1,404 $ 547 Realized and Unrealized Net Gains (Losses): Included in Net Income (38 ) 968 Transfers to Loans Held for Sale — (1,198 ) Variation Margin Payments — 74 Balance as of June 30, 2018 $ 1,366 $ 391 Total Unrealized Net Gains (Losses) Included in Net Income $ — $ 391 Six Months Ended June 30, 2019 Balance as of January 1, 2019 $ 1,290 $ 4,416 Realized and Unrealized Net Gains (Losses): Included in Net Income (78 ) 5,243 Transfers to Loans Held for Sale — (4,014 ) Variation Margin Payments — 14,311 Balance as of June 30, 2019 $ 1,212 $ 19,956 Total Unrealized Net Gains (Losses) Included in Net Income $ — $ 19,956 Six Months Ended June 30, 2018 Balance as of January 1, 2018 $ 1,454 $ 894 Realized and Unrealized Net Gains (Losses): Included in Net Income (88 ) 1,505 Transfers to Loans Held for Sale — (1,580 ) Variation Margin Payments — (428 ) Balance as of June 30, 2018 $ 1,366 $ 391 Total Unrealized Net Gains (Losses) Included in Net Income $ — $ 391 1 Realized and unrealized gains and losses related to mortgage servicing rights are reported as a component of mortgage banking income in the Company’s consolidated statements of income. 2 Realized and unrealized gains and losses related to interest rate lock commitments are reported as a component of mortgage banking income in the Company’s consolidated statements of income. Realized and unrealized gains and losses related to interest rate swap agreements are reported as a component of other noninterest income in the Company’s consolidated statements of income. For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of June 30, 2019 and December 31, 2018 , the significant unobservable inputs used in the fair value measurements were as follows: Significant Unobservable Inputs (weighted-average) Fair Value (dollars in thousands) Valuation Technique Description June 30, Dec. 31, June 30, Dec. 31, Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 1 10.39 % 7.01 % $ 26,117 $ 30,508 Discount Rate 2 7.49 % 9.59 % Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 88.21 % 89.00 % $ 2,143 $ 871 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.21 % 0.06 % $ 17,813 $ 3,545 1 Represents annualized loan repayment rate assumption. 2 Derived from multiple interest rate scenarios that incorporate a spread to a market yield curve and market volatilities. The significant unobservable inputs used in the fair value measurement of the Company’s mortgage servicing rights are the weighted-average constant prepayment rate and weighted-average discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they generally move in opposite directions of each other. The Company estimates the fair value of mortgage servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The Company’s Treasury Division enters observable and unobservable inputs into the model to arrive at an estimated fair value. To assess the reasonableness of the fair value measurement, the Treasury Division performs a back-test by comparing the model’s results to historical prepayment data. The Treasury Division also compares the fair value of the Company’s mortgage servicing rights to a value calculated by an independent third party. Discussions are held with members from the Treasury, Mortgage Banking, and Controllers Divisions, along with the independent third party to discuss and reconcile the fair value estimates and key assumptions used by the respective parties in arriving at those estimates. A subcommittee of the Company’s Asset/Liability Management Committee is responsible for providing oversight over the valuation methodology and key assumptions. The significant unobservable input used in the fair value measurement of the Company’s IRLCs is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. Generally, the fair value of an IRLC is positive (negative) if the prevailing interest rate is lower (higher) than the IRLC rate. Therefore, an increase in the closing ratio (i.e., higher percentage of loans are estimated to close) will increase the gain or loss. The closing ratio is largely dependent on the loan processing stage that a loan is currently in and the change in prevailing interest rates from the time of the rate lock. The closing ratio is computed by the Company’s secondary marketing system using historical data and the ratio is periodically reviewed by the Company for reasonableness. The unobservable input used in the fair value measurement of the Company’s interest rate swap agreements is the credit factor. This factor represents the risk that a counterparty is either unable or unwilling to settle a transaction in accordance with the underlying contractual terms. A significant increase (decrease) in the credit factor could result in a significantly lower (higher) fair value measurement. The credit factor is determined by the Treasury Division based on the risk rating assigned to each counterparty in which the Company holds a net asset position. The Company’s Credit Policy Committee periodically reviews and approves the Expected Default Frequency of the Economic Capital Model for Credit Risk. The Expected Default Frequency is used as the credit factor for interest rate swap agreements. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company may be required periodically to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets. The following table represents the assets measured at fair value on a nonrecurring basis as of June 30, 2019 . There were no assets measured at fair value on a nonrecurring basis as of December 31, 2018 . (dollars in thousands) Fair Value Hierarchy Net Carrying Amount Valuation Allowance June 30, 2019 Mortgage Servicing Rights - amortization method Level 3 $ 24,905 $ (10 ) The write-down of mortgage servicing rights accounted for under the amortization method was primarily due to changes in certain key assumptions used to estimate fair value. As previously mentioned, all of the Company's mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Fair Value Option The Company elects the fair value option for all residential mortgage loans held for sale. This election allows for a more effective offset of the changes in fair values of the loans held for sale and the derivative financial instruments used to financially hedge them without having to apply complex hedge accounting requirements. As noted above, the fair value of the Company’s residential mortgage loans held for sale was determined based on quoted prices for similar loans in active markets. The following table reflects the difference between the aggregate fair value and the aggregate unpaid principal balance of the Company’s residential mortgage loans held for sale as of June 30, 2019 and December 31, 2018 . (dollars in thousands) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Unpaid Principal June 30, 2019 Loans Held for Sale $ 22,706 $ 22,102 $ 604 December 31, 2018 Loans Held for Sale $ 10,987 $ 10,656 $ 331 Changes in the estimated fair value of residential mortgage loans held for sale are reported as a component of mortgage banking income in the Company’s consolidated statements of income. For the three and six months ended June 30, 2019 and 2018 , the net gains or losses from the change in fair value of the Company’s residential mortgage loans held for sale were not material. Financial Instruments Not Recorded at Fair Value on a Recurring Basis The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments not recorded at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 . This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For non-marketable equity securities such as Federal Home Loan Bank and Federal Reserve Bank stock, the carrying amount is a reasonable estimate of fair value as these securities can only be redeemed or sold at their par value and only to the respective issuing government supported institution or to another member institution. For financial liabilities such as noninterest-bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent ASUs that modified Topic 606. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities, which comprise the majority of the Company’s revenue. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not within the scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. However, the recognition of these covered revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below. Trust and Asset Management Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Fees, Exchange, and Other Service Charges Fees, exchange, and other service charges are primarily comprised of debit card income, ATM fees, merchant services income, and other service charges. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Annuity and Insurance Annuity and insurance income primarily consists of commissions received on annuity product sales. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the annuity policy. Shortly after the policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue. The Company does not earn a significant amount of trailer fees on annuity sales. The majority of the trailer fees relates to variable annuity products and are calculated based on a percentage of market value at period end. Revenue is not recognized until the annuity’s market value can be determined. Other Other noninterest income consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments, investment advisor fees from the Company’s Managed Account Platform Services (MAPS) wealth management product, safety deposit box rental fees, and other miscellaneous revenue streams. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees (i.e., trailers) from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined. Investment advisor fees from the MAPS wealth management product is earned over time and based on an annual percentage rate of the net asset value. The investment advisor fees are charged to the customer’s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three and six months ended June 30, 2019 and 2018 . Three Months Ended Six Months Ended (dollars in thousands) 2019 2018 2019 2018 Noninterest Income In-scope of Topic 606: Trust and Asset Management $ 11,385 $ 11,356 $ 22,146 $ 22,537 Service Charges on Deposit Accounts 3,295 3,214 6,644 6,788 Fees, Exchange, and Other Service Charges 11,602 11,457 23,154 23,050 Annuity and Insurance 1,772 1,796 4,316 2,940 Other 2,504 2,532 4,975 4,810 Noninterest Income (in-scope of Topic 606) 30,558 30,355 61,235 60,125 Noninterest Income (out-of-scope of Topic 606) 14,892 10,943 27,894 25,208 Total Noninterest Income $ 45,450 $ 41,298 $ 89,129 $ 85,333 Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of June 30, 2019 and December 31, 2018 , the Company did not have any significant contract balances. Contract Acquisition Costs In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.

Leases [Abstract]
Lessee, Operating Leases	Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842. For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. Lessee Accounting Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches, ATM locations, and office space with terms extending through 2052. Portions of certain properties are subleased for terms extending through 2033. Substantially all of the Company’s leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated statements of condition. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated statements of condition as a right-of-use (“ROU”) asset and a corresponding lease liability. The Company has one existing finance lease (previously referred to as a capital lease) for a portion of the Company’s headquarters’ building with a lease term through 2052. As this lease was previously required to be recorded on the Company’s consolidated statements of condition, Topic 842 did not materially impact the accounting for this lease. The following table represents the consolidated statements of condition classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the consolidated statements of condition.

The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the Company’s only finance lease, the Company utilized its incremental borrowing rate at lease inception.

As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Bank of Hawaii Corporation (the “Parent”) is a Delaware corporation and a bank holding company headquartered in Honolulu, Hawaii. Bank of Hawaii Corporation and its subsidiaries (collectively, the “Company”) provide a broad range of financial products and services to customers in Hawaii, Guam, and other Pacific Islands. The accompanying consolidated financial statements include the accounts of the Parent and its subsidiaries. The Parent’s principal operating subsidiary is Bank of Hawaii (the “Bank”). The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period information has been reclassified to conform to the current period presentation. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the full fiscal year or for any future period. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and accompanying notes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements.
Variable Interest Entities	Variable Interest Entities Variable interests are defined as contractual ownership or other interests in an entity that change with fluctuations in an entity’s net asset value. The primary beneficiary consolidates the variable interest entity (“VIE”). The primary beneficiary is defined as the enterprise that has both (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. The Company has limited partnership interests in several low-income housing partnerships. These partnerships provide funds for the construction and operation of apartment complexes that provide affordable housing to lower-income households. If these developments successfully attract a specified percentage of residents falling in that lower-income range, state and/or federal income tax credits are made available to the partners. The tax credits are generally recognized over 10 years . In order to continue receiving the tax credits each year over the life of the partnership, the low-income residency targets must be maintained. Prior to January 1, 2015, the Company utilized the effective yield method whereby the Company recognized tax credits generally over 10 years and amortized the initial cost of the investment to provide a constant effective yield over the period that tax credits are allocated to the Company. On January 1, 2015, the Company adopted ASU No. 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects” prospectively for new investments. ASU No. 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. As permitted by ASU No. 2014-01, the Company elected to continue to utilize the effective yield method for investments made prior to January 1, 2015. Unfunded commitments to fund these low-income housing partnerships were $12.8 million and $15.2 million as of June 30, 2019 and December 31, 2018 , respectively. These unfunded commitments are unconditional and legally binding and are recorded in other liabilities in the consolidated statements of condition. See Note 6 Affordable Housing Projects Tax Credit Partnerships for more information. The Company also has limited partnership interests in solar energy tax credit partnership investments. These partnerships develop, build, own and operate solar renewable energy projects. Over the course of these investments, the Company expects to receive federal and state tax credits, tax-related benefits, and excess cash available for distribution, if any. The Company may be called to sell its interest in the limited partnerships through a call option once all investment tax credits have been recognized. Tax benefits associated with these investments are generally recognized over 6 years . Although these entities meet the definition of a VIE, the Company is not the primary beneficiary of the entities as the general partner has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. While the partnership agreements allow the limited partners, through a majority vote, to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause. The investments in these entities are initially recorded at cost, which approximates the maximum exposure to loss as a result of the Company’s involvement with these unconsolidated entities. The balance of the Company’s investments in these entities was $78.9 million and $85.9 million as of June 30, 2019 and December 31, 2018 , respectively, and is included in other assets in the consolidated statements of condition.
Accounting Standards Adopted in the Current Year or Pending Adoption	Accounting Standards Adopted in 2019 In February 2016, the FASB issued ASU No. 2016-02, “Leases.” Under the new guidance, lessees will be required to recognize the following for all 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. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard . All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. As the Company elected the transition option provided in ASU No. 2018-11 (see below), the modified retrospective approach was applied on January 1, 2019 (as opposed to January 1, 2017). The Company also elected certain relief options offered in ASU 2016-02 including the package of practical expedients, the option not to separate lease and non-lease components and instead to account for them as a single lease component, and the option not to recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e., leases with terms of twelve months or less). The Company did not elect the hindsight practical expedient, which allows entities to use hindsight when determining lease term and impairment of right-of-use assets. The Company has several lease agreements, such as branch locations, which are considered operating leases, and therefore, were not previously recognized on the Company’s consolidated statements of condition. The new guidance requires these lease agreements to be recognized on the consolidated statements of condition as a right-of-use asset and a corresponding lease liability. The new guidance did not have a material impact on the consolidated statements of income or the consolidated statements of cash flows. See Note 16 Leases for more information. In August 2017, the FASB issued ASU No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This ASU’s objectives 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. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018. The Company currently does not designate any derivative financial instruments as formal hedging relationships, and therefore, does not currently utilize hedge accounting. As such, ASU No. 2017-12 did not impact the Company’s Consolidated Financial Statements. In July 2018, the FASB issued ASU No. 2018-11, “Leases - Targeted Improvements” to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02 (January 1, 2019 for the Company). The Company adopted ASU 2018-11 on its required effective date of January 1, 2019 and elected both transition options mentioned above. ASU 2018-11 did not have a material impact on the Company’s Consolidated Financial Statements. In December 2018, the FASB issued ASU No. 2018-20, “Narrow-Scope Improvements for Lessors.” This ASU (1) allows lessors to make an accounting policy election of presenting sales taxes and other similar taxes collected from lessees on a net basis, (2) requires a lessor to exclude lessor costs paid directly by a lessee to third parties on the lessor’s behalf and include lessor costs that are paid by the lessor and reimbursed by the lessee in the measurement of variable lease revenue and the associated expense, and (3) clarifies that when lessors allocate variable payments to lease and non-lease components they are required to follow the recognition guidance in the new leases standard for the lease component and other applicable guidance, such as the new revenue standard, for the non-lease component. The Company adopted ASU 2018-20 on its required effective date of January 1, 2019 and elected to present sales taxes and other similar taxes collected from lessees on a net basis as described in (1) above. ASU 2018-20 did not have a material impact on the Company’s Consolidated Financial Statements. In March 2019, the FASB issued ASU No. 2019-01, “Leases: Codification Improvements.” This ASU (1) states that for lessors that are not manufacturers or dealers, the fair value of the underlying asset is its cost, less any volume or trade discounts, as long as there isn’t a significant amount of time between acquisition of the asset and lease commencement; (2) clarifies that lessors in the scope of ASC 942 (such as the Company) must classify principal payments received from sales-type and direct financing leases in investing activities in the statement of cash flows; and (3) clarifies the transition guidance related to certain interim disclosures provided in the year of adoption. To coincide with the adoption of ASU No. 2016-02, the Company elected to early adopt ASU 2019-01 on January 1, 2019. The adoption of this ASU did not have a material impact on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued ASU No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” With respect to Topic 815, Derivatives and Hedging, ASU 2019-04 clarifies that the reclassification of a debt security from held-to-maturity (“HTM”) to available-for-sale (“AFS”) under the transition guidance in ASU 2017-12 would not (1) call into question the classification of other HTM securities, (2) be required to actually designate any reclassified security in a last-of-layer hedge, or (3) be restricted from selling any reclassified security. As part of the transition of ASU 2019-04, entities may reclassify securities that would qualify for designation as the hedged item in a last-of-layer hedging relationship from HTM to AFS; however, entities that already made such a reclassification upon their adoption of ASU 2017-12 are precluded from reclassifying additional securities. The Company did not reclassify any securities from HTM to AFS upon adoption of ASU 2017-12. The Company elected to early adopt the amendments to Topic 815 in June 2019. See Note 3 Investment Securities for more information regarding the impact of the transfer of certain HTM debt securities to AFS. The amendments and pending adoption to Topics 326 and 825 are described in the section below. Accounting Standards Pending Adoption In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace today’s “incurred loss” approach with an “expected loss” approach known as current expected credit loss (“CECL”), which will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL approach will not apply to AFS debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the credit losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019 and the Company is planning to adopt the standard in the first quarter of 2020. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company is continuing its implementation efforts through its Company-wide implementation team. This team has assigned roles and responsibilities, key tasks to complete, and a general timeline to be followed. The team meets periodically to discuss the latest developments and ensure progress is being made. The team has been working with an advisory consultant and has finalized and documented the methodologies that will be utilized. The team is currently developing controls, processes, policies and disclosures in preparation for performing a full end to end parallel run. The Company’s preliminary evaluation indicates the provisions of ASU No. 2016-13 are expected to impact the Company’s Consolidated Financial Statements, in particular the level of the reserve for credit losses. The Company is continuing to evaluate the extent of the potential impact and expects that portfolio composition and economic conditions at the time of adoption will be a factor. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. As ASU No. 2018-13 only revises disclosure requirements, it will not have a material impact on the Company’s Consolidated Financial Statements. As mentioned in the previous section the FASB issued ASU No. 2019-04 in April 2019. With respect to Topic 326, Financial Instruments - Credit Losses, ASU 2019-04 clarifies the scope of the credit losses standard and addresses issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments, among other things. With respect to Topic 825, Financial Instruments, on recognizing and measuring financial instruments, ASU 2019-04 addresses the scope of the guidance, the requirement for remeasurement under ASC 820 when using the measurement alternative, certain disclosure requirements and which equity securities have to be remeasured at historical exchange rates. The amendments to Topic 326 have the same effective dates as ASU 2016-13 (i.e., the first quarter of 2020). The Company is currently evaluating the potential impact of Topic 326 amendments on the Company’s Consolidated Financial Statements. The amendments to Topic 825 are effective for interim and annual reporting periods beginning after December 15, 2019 and are not expected to have a material impact on the Company’s Consolidated Financial Statements. In May 2019, the FASB issued ASU No. 2019-05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. ASU 2019-05 has the same effective date as ASU 2016-13 (i.e., the first quarter of 2020). The Company does not expect to elect the fair value option, and therefore, ASU 2019-05 is not expected to impact the Company’s Consolidated Financial Statements.

Summary of the significant unobservable inputs	For Level 3 assets and liabilities measured at fair value on a recurring or nonrecurring basis as of June 30, 2019 and December 31, 2018 , the significant unobservable inputs used in the fair value measurements were as follows: Significant Unobservable Inputs (weighted-average) Fair Value (dollars in thousands) Valuation Technique Description June 30, Dec. 31, June 30, Dec. 31, Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 1 10.39 % 7.01 % $ 26,117 $ 30,508 Discount Rate 2 7.49 % 9.59 % Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 88.21 % 89.00 % $ 2,143 $ 871 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.21 % 0.06 % $ 17,813 $ 3,545 1 Represents annualized loan repayment rate assumption. 2 Derived from multiple interest rate scenarios that incorporate a spread to a market yield curve and market volatilities.
Assets and liabilities measured at fair value on a nonrecurring basis	The Company may be required periodically to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower-of-cost-or-fair value accounting or impairment write-downs of individual assets. The following table represents the assets measured at fair value on a nonrecurring basis as of June 30, 2019 . There were no assets measured at fair value on a nonrecurring basis as of December 31, 2018 .

Schedule of difference between the aggregate fair value and the aggregate unpaid principal balance of the Company's residential mortgage loans held for sale	The following table reflects the difference between the aggregate fair value and the aggregate unpaid principal balance of the Company’s residential mortgage loans held for sale as of June 30, 2019 and December 31, 2018 . (dollars in thousands) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Unpaid Principal June 30, 2019 Loans Held for Sale $ 22,706 $ 22,102 $ 604 December 31, 2018 Loans Held for Sale $ 10,987 $ 10,656 $ 331
Schedule of carrying amount, fair value, and fair value hierarchy of financial instruments	The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments not recorded at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 . This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For non-marketable equity securities such as Federal Home Loan Bank and Federal Reserve Bank stock, the carrying amount is a reasonable estimate of fair value as these securities can only be redeemed or sold at their par value and only to the respective issuing government supported institution or to another member institution. For financial liabilities such as noninterest-bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.
