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 Parent’s principal operating subsidiary is Bank of Hawaii (the “Bank”). All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements of the Company 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. In the opinion of management, the consolidated financial statements reflect normal recurring adjustments necessary for a fair presentation of the results for the interim periods. Certain prior period information has been reclassified to conform to the current period presentation. These statements 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, 2014 . Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 . 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. Accounting Standards Adopted in 2015 In January 2014, the FASB issued ASU No. 2014-01, "Accounting for Investments in Qualified Affordable Housing Projects." 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. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. This new guidance also requires new disclosures for all investors in these projects (see Note 5 to the Consolidated Financial Statements). The Company adopted ASU No. 2014-01 effective January 1, 2015. Upon adoption, the guidance must be applied retrospectively to all periods presented. However, entities that used the effective yield method to account for investments in these projects before adoption may continue to do so for these pre-existing investments. Prior to adoption of ASU No. 2014-01, the Company accounted for such investments using the effective yield method and continued to do so for these pre-existing investments after adopting ASU No. 2014-01. The Company expects future investments to meet the criteria required for the proportional amortization method and plans to make such an accounting policy election. There were no new investments being amortized since the adoption of ASU No. 2014-01 on January 1, 2015, and therefore, the adoption of ASU No. 2014-01 has not had a material impact on the Company's Consolidated Financial Statements. In January 2014, the FASB issued ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both: (1) the amount of foreclosed residential real estate property held by the creditor; and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The Company adopted ASU No. 2014-04 effective January 1, 2015. The adoption of ASU No. 2014-04 did not have a material impact on the Company's Consolidated Financial Statements. In June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." The new guidance aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. The amendments in the ASU require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The amendments in the ASU also require expanded disclosures, effective June 30, 2015, about the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings (see Note 6 to the Consolidated Financial Statements). The Company adopted the amendments in this ASU effective January 1, 2015. As of September 30, 2015 , all of the Company's repurchase agreements were typical in nature (i.e., not repurchase-to-maturity transactions or repurchase agreements executed as a repurchase financing) and are accounted for as secured borrowings. As such, the adoption of ASU No. 2014-11 did not have a material impact on the Company's Consolidated Financial Statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718, Compensation - Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. However, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. Entities may apply the amendments in this ASU either: (1) prospectively to all awards granted or modified after the effective date; or (2) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company adopted ASU No. 2014-12 effective January 1, 2015. As of September 30, 2015 , the Company did not have any share-based payment awards that included performance targets that could be achieved after the requisite service period. As such, the adoption of ASU No. 2014-12 did not have a material impact on the Company's Consolidated Financial Statements. In August 2014, the FASB issued ASU No. 2014-14, “Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The objective of this guidance is to reduce diversity in practice related to how creditors classify government-guaranteed mortgage loans, including FHA and VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure; (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The Company adopted ASU No. 2014-14 effective January 1, 2015. The adoption of ASU No. 2014-14 did not have a material impact on the Company's Consolidated Financial Statements. Accounting Standards Pending Adoption In May 2014, the FASB and the International Accounting Standards Board (the "IASB") jointly issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP and International Financial Reporting Standards ("IFRS"). Previous revenue recognition guidance in GAAP comprised broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes resulted in different accounting for economically similar transactions. In contrast, IFRS provided limited revenue recognition guidance and, consequently, could be difficult to apply to complex transactions. Accordingly, the FASB and the IASB initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosure requirements; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. To meet those objectives, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." 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. In doing so, companies generally will be required to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard was initially effective for public entities for interim and annual reporting periods beginning after December 15, 2016; early adoption is not permitted. However, in August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers - Deferral of the Effective Date" which defers the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09 and will be closely monitoring developments and additional guidance to determine the potential impact the new standard will have on the Company's Consolidated Financial Statements. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidation Analysis.” This ASU affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU No. 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015. The adoption of ASU No. 2015-02 is not expected to have a material impact on the Company's Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU No. 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company’s current method of accounting for fees paid in a cloud computing arrangement is consistent with the accounting guidance provided by ASU No. 2015-05. Therefore, the adoption of ASU No. 2015-05 is not expected to have a material impact on the Company's Consolidated Financial Statements.

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 September 30, 2015 and December 31, 2014 , the gross unrealized losses reported for mortgage-backed securities were primarily 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 nine months ended September 30, 2015 and 2014 were as follows: Three Months Ended Nine Months Ended (dollars in thousands) 2015 2014 2015 2014 Taxable $ 25,569 $ 31,053 $ 82,638 $ 96,796 Non-Taxable 5,312 5,300 15,953 15,841 Total Interest Income from Investment Securities $ 30,881 $ 36,353 $ 98,591 $ 112,637 As of September 30, 2015 , included in the Company's investment securities portfolio were debt securities issued by political subdivisions within the State of Hawaii of $579.0 million , representing 58% of the total fair value of the Company's municipal debt securities. Of the entire Hawaii municipal bond portfolio, 91% were credit-rated Aa2 or better by Moody's while most of the remaining Hawaii municipal bonds were credit-rated A2 or better by at least one nationally recognized statistical rating organization. Of the Company's total Hawaii municipal bond holdings, 77% were general obligation issuances. As of September 30, 2015 , there were no other holdings of municipal debt securities that were issued by a single state or political subdivision which comprised more than 10% of the total fair value of the Company's municipal debt securities. As of September 30, 2015 and December 31, 2014 , the carrying value of the Company’s Federal Home Loan Bank of Des Moines (“FHLB Des Moines”) stock and Federal Reserve Bank stock was as follows: (dollars in thousands) September 30, December 31, Federal Home Loan Bank Stock $ 20,000 $ 47,075 Federal Reserve Bank Stock 19,836 19,299 Total $ 39,836 $ 66,374 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. 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. Effective May 31, 2015, FHLB Des Moines completed its previously announced merger with the Federal Home Loan Bank of Seattle (“FHLB Seattle”). The continuing bank, FHLB Des Moines, remains headquartered in Des Moines with a western regional office in Seattle. Prior to the merger, the Company held stock in FHLB Seattle. Pursuant to the terms of the Merger Agreement, each share of FHLB Seattle stock was converted into one share of FHLB Des Moines stock. In addition, upon the merger, the Company's excess FHLB stock was redeemed and the Company’s membership effectively transferred to FHLB Des Moines. The merger did not have a material impact on the Company's Consolidated Financial Statements or the Company's dealings with the continuing bank. 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 is 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 not be sufficient 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 September 30, 2015 , the conversion ratio was 1.6483 . During the first nine months of 2015 , the Company recorded a $10.1 million net gain on the sale of 95,000 Visa Class B shares. Concurrent with these sales, the Company entered 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 288,714 Class B shares ( 475,887 Class A equivalents) that the Company owns are carried at a zero cost basis. The Company also contributed 13,800 Visa Class B restricted shares to the Bank of Hawaii Foundation during the first nine months of 2015 . The contribution had no impact on noninterest expense; however, the contribution favorably impacted our effective tax rate in 2015 .

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 in the classes within the commercial portfolio segment 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. The special mention credit quality indicator is not used for classes of loans and leases that are included in the consumer portfolio segment. 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.

For the three and nine months ended September 30, 2015 and 2014 , 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 that remained on accrual status. For the three and nine months ended September 30, 2015 and 2014 , 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 troubled debt restructuring (“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 $66.3 million and $60.2 million as of September 30, 2015 and December 31, 2014 , respectively. There were no commitments to lend additional funds on loans modified in a TDR as of September 30, 2015 and December 31, 2014 . 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 consumer and commercial 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. Management exercises significant judgment in developing these estimates.

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 $7.0 million as of September 30, 2015 .

Mortgage Servicing Rights

Mortgage Servicing Rights	9 Months Ended
	Sep. 30, 2015
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 $2.7 billion as of September 30, 2015 and $2.9 billion as of December 31, 2014 . Substantially all of these loans were originated by the Company and sold to third parties on a non-recourse basis with servicing rights retained. These retained servicing rights are recorded as a servicing asset and are initially recorded at fair value (see Note 13 to the Consolidated Financial Statements 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 and $2.0 million for the three months ended September 30, 2015 and 2014 , respectively, and $5.4 million and $6.0 million for the nine months ended September 30, 2015 and 2014 , respectively. 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 nine months ended September 30, 2015 and 2014 , 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 Nine Months Ended (dollars in thousands) 2015 2014 2015 2014 Balance at Beginning of Period $ 2,188 $ 2,960 $ 2,604 $ 3,826 Change in Fair Value: Due to Change in Valuation Assumptions 1 — (145 ) (251 ) (816 ) Due to Payoffs (116 ) (72 ) (281 ) (267 ) Total Changes in Fair Value of Mortgage Servicing Rights (116 ) (217 ) (532 ) (1,083 ) Balance at End of Period $ 2,072 $ 2,743 $ 2,072 $ 2,743 1 Primarily represents changes in discount rates and loan repayment rate assumptions, mostly due to changes in interest rates. For the three and nine months ended September 30, 2015 and 2014 , the change in the carrying value of the Company’s mortgage servicing rights accounted for under the amortization method, net of valuation allowance, was as follows: Three Months Ended Nine Months Ended (dollars in thousands) 2015 2014 2015 2014 Balance at Beginning of Period $ 21,238 $ 23,437 $ 22,091 $ 24,297 Servicing Rights that Resulted From Asset Transfers 645 100 1,330 664 Amortization (633 ) (742 ) (2,228 ) (2,094 ) Valuation Allowance Provision (21 ) 21 36 (51 ) Balance at End of Period $ 21,229 $ 22,816 $ 21,229 $ 22,816 Valuation Allowance: Balance at Beginning of Period $ — $ (72 ) $ (57 ) $ — Valuation Allowance Provision (21 ) 21 36 (51 ) Balance at End of Period $ (21 ) $ (51 ) $ (21 ) $ (51 ) Fair Value of Mortgage Servicing Rights Accounted for Under the Amortization Method Beginning of Period $ 26,205 $ 25,848 $ 22,837 $ 30,100 End of Period $ 24,419 $ 24,336 $ 24,419 $ 24,336 The key data and assumptions used in estimating the fair value of the Company’s mortgage servicing rights as of September 30, 2015 and December 31, 2014 were as follows: September 30, December 31, 2014 Weighted-Average Constant Prepayment Rate 1 10.01 % 11.62 % Weighted-Average Life (in years) 6.98 6.28 Weighted-Average Note Rate 4.23 % 4.28 % Weighted-Average Discount Rate 2 9.71 % 10.61 % 1 Represents annualized loan repayment rate assumption. 2 Derived from multiple interest rate scenarios that incorporate a spread to the London Interbank Offered Rate swap curve and market volatilities. A sensitivity analysis of the Company’s fair value of mortgage servicing rights to changes in certain key assumptions as of September 30, 2015 and December 31, 2014 is presented in the following table. (dollars in thousands) September 30, December 31, Constant Prepayment Rate Decrease in fair value from 25 basis points (“bps”) adverse change $ (285 ) $ (265 ) Decrease in fair value from 50 bps adverse change (565 ) (524 ) Discount Rate Decrease in fair value from 25 bps adverse change (284 ) (250 ) Decrease in fair value from 50 bps adverse change (562 ) (495 ) 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	9 Months Ended
	Sep. 30, 2015
Equity Method Investments and Joint Ventures [Abstract]
Low Income Housing Tax Credit Partnerships	Affordable Housing Projects Tax Credit Partnerships The Company makes certain 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 Partnership. Each limited partnership is managed by an unrelated third party general partner who exercises full 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 consent to 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 will be recognized using the proportional amortization method.

Balance Sheet Offsetting

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 marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds. The Company had net liability positions with its financial institution counterparties totaling $15.6 million and $16.2 million as of September 30, 2015 and December 31, 2014 , respectively. See Note 11 to the Consolidated Financial Statements 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., fails 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 September 30, 2015 , disaggregated by the class of collateral pledged.

For repurchase agreements with private institutions, the fair value of investment securities pledged was $0.7 billion as of September 30, 2015 and December 31, 2014 . For repurchase agreements with government entities, the investment securities pledged to each government entity collectively secure both deposits as well as repurchase agreements. The Company had government entity deposits totaling $1.2 billion and $1.3 billion as of September 30, 2015 and December 31, 2014 , respectively. The investment securities pledged as of September 30, 2015 and December 31, 2014 had a fair value of $1.9 billion and $2.1 billion , respectively.

Business Segments

Business Segments	9 Months Ended

Segment Reporting [Abstract]
Business Segments	Business Segments The Company’s business segments are defined as Retail Banking, Commercial Banking, Investment Services, 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 similar information for any other financial institution, uses various techniques to assign balance sheet and income statement amounts to the business segments, including allocations of income, expense, the provision for credit losses, and capital. This process is dynamic and requires certain allocations based on judgment and other subjective factors. Unlike financial accounting, there is no comprehensive authoritative guidance for management accounting that is equivalent to GAAP. 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 our consolidated Allowance. The residual provision for credit losses to arrive at the consolidated provision for credit losses is included in Treasury and Other. Noninterest income and expense includes allocations from support units to business units. These allocations are based on actual usage where practicably calculated or by management’s estimate of such usage. The provision for income taxes is allocated to business segments using a 37% effective tax rate. However, the provision for income taxes for our 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 tax rates due to the unique relationship that income taxes have with their products. The residual income tax expense or benefit to arrive at the consolidated effective tax rate is included in Treasury and Other. 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, small business loans and leases, and credit cards. Deposit products include checking, savings, and time deposit accounts. Retail Banking also offers retail insurance products. Products and services from Retail Banking are delivered to customers through 72 branch locations and 455 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. 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 small business customers. Investment Services Investment Services includes private and international client banking, 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 group assists 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, government deposits, 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 September 30, 2015 and December 31, 2014 , 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, interest rate 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 interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting interest rate swap agreements with highly rated third party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value in the Company's 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 marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds. See Note 6 to the Consolidated Financial Statements for more information. The Company’s interest rate swap agreements with institutional counterparties contain credit-risk-related contingent features tied to the Company’s debt ratings or capitalization levels. Under these provisions, if the Company’s debt rating falls below investment grade or if the Company’s capitalization levels fall below stipulated thresholds, certain counterparties may require immediate and ongoing collateralization on interest rate swaps in net liability positions, or may require immediate settlement of the contracts. As of September 30, 2015 , the Company’s debt ratings and capital levels were in excess of these minimum requirements. 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. This conversion rate swap agreement is usually valued at zero (i.e., no contingent liability recorded) as a drop in the conversion ratio is deemed by the Company to be neither probable nor reasonably estimable. However, in September 2014, Visa announced a reduction of the conversion ratio. As a result, the Company recorded a $0.1 million liability in September 2014 which represented the amount paid to the buyer in October 2014. As of September 30, 2015 , the conversion rate swap agreement was valued at zero as further reductions to the conversion ratio were deemed neither probable nor reasonably estimable by management. See Note 2 to the Consolidated Financial Statements for more information.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, and Guarantees	Commitments, Contingencies, and Guarantees The Company’s credit commitments as of September 30, 2015 and December 31, 2014 were as follows: (dollars in thousands) September 30, December 31, Unfunded Commitments to Extend Credit $ 2,477,839 $ 2,388,432 Standby Letters of Credit 43,952 48,157 Commercial Letters of Credit 17,669 14,130 Total Credit Commitments $ 2,539,460 $ 2,450,719 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 The Company is subject to various pending and threatened legal proceedings arising out of the normal course of business or operations. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing 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 other actions 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 those 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 September 30, 2015 , the unpaid principal balance of residential mortgage loans sold by the Company was $2.6 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 nine months ended September 30, 2015 , there were three residential mortgage loans repurchased with an aggregate unpaid principal balance of $0.9 million as a result of the representation and warranty provisions contained in these contracts. Two of these loans were delinquent as to principal and interest at the time of repurchase, however, no losses were incurred related to these repurchases. As of September 30, 2015 , 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 nine months ended September 30, 2015 , there were no loans repurchased related to loan servicing activities. As of September 30, 2015 , 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 September 30, 2015 , 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 September 30, 2015 , 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	9 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. Management maximizes the use of observable inputs and minimizes the use of unobservable inputs when determining fair value measurements. Management reviews and updates the fair value hierarchy classifications of the Company’s assets and liabilities on a quarterly basis. 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 non-binding third-party broker quotes, as well as a review of market-related conditions impacting the information provided by the Company’s third-party pricing service. Management primarily identifies investment securities which may have traded in illiquid or inactive markets by identifying instances of a significant decrease in the volume or frequency of trades relative to historical levels, as well as instances of a significant widening of the bid-ask spread in the brokered markets. Investment securities that are deemed to have been trading in illiquid or inactive markets may require the use of significant unobservable inputs to determine fair value. As of September 30, 2015 and December 31, 2014 , management did not make adjustments to prices provided by the third-party pricing service as a result of illiquid or inactive markets. On a quarterly basis, management also reviews a sample of securities priced by the Company’s third-party pricing service to review significant assumptions and valuation methodologies used. 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. The Company’s third-party pricing service has also established processes for us to submit inquiries regarding quoted prices. Periodically, we will challenge the quoted prices provided by our 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. 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 we believe market participants would use in estimating future net servicing income. Significant assumptions in the valuation of mortgage servicing rights include estimated loan repayment rates, the discount rate, servicing costs, and the timing of cash flows, among other factors. Mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other Assets Other assets recorded at fair value on a recurring basis are primarily comprised of investments related to deferred compensation arrangements. Quoted prices for these investments, primarily in mutual funds, are available in active markets. Thus, the Company’s investments related to deferred compensation arrangements are classified as Level 1 measurements in the fair value hierarchy. Derivative Financial Instruments Derivative financial instruments recorded at fair value on a recurring basis are comprised of interest rate lock commitments (“IRLCs”), forward commitments, interest rate swap agreements, foreign exchange contracts, and Visa Class B to Class A shares conversion rate swap agreements. The fair values of IRLCs are calculated based on the value of the underlying loan, 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 the LIBOR swap 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 agreement represents 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 dates. As of September 30, 2015 and December 31, 2014 , the conversion rate swap agreement was valued at zero as reductions to the conversion ratio were neither probable nor reasonably estimable by management. This conversion rate swap agreement is classified as a Level 2 measurement. See Note 11 to the Consolidated Financial Statements 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 September 30, 2015 and December 31, 2014 : 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 September 30, 2015 Assets: Investment Securities Available-for-Sale Debt Securities Issued by the U.S. Treasury and Government Agencies $ 60,706 $ 307,951 $ — $ 368,657 Debt Securities Issued by States and Political Subdivisions — 737,210 — 737,210 Debt Securities Issued by Corporations — 310,561 — 310,561 Mortgage-Backed Securities: Residential - Government Agencies — 348,469 — 348,469 Residential - U.S. Government-Sponsored Enterprises — 412,261 — 412,261 Commercial - Government Agencies — 102,564 — 102,564 Total Mortgage-Backed Securities — 863,294 — 863,294 Total Investment Securities Available-for-Sale 60,706 2,219,016 — 2,279,722 Loans Held for Sale — 3,222 — 3,222 Mortgage Servicing Rights — — 2,072 2,072 Other Assets 19,548 — — 19,548 Derivatives 1 — 186 16,614 16,800 Total Assets Measured at Fair Value on a $ 80,254 $ 2,222,424 $ 18,686 $ 2,321,364 Liabilities: Derivatives 1 $ — $ 39 $ 16,212 $ 16,251 Total Liabilities Measured at Fair Value on a $ — $ 39 $ 16,212 $ 16,251 December 31, 2014 Assets: Investment Securities Available-for-Sale Debt Securities Issued by the U.S. Treasury and Government Agencies $ 61,271 $ 269,987 $ — $ 331,258 Debt Securities Issued by States and Political Subdivisions — 743,970 — 743,970 Debt Securities Issued by Corporations — 294,833 — 294,833 Mortgage-Backed Securities: Residential - Government Agencies — 462,436 — 462,436 Residential - U.S. Government-Sponsored Enterprises — 278,461 — 278,461 Commercial - Government Agencies — 178,232 — 178,232 Total Mortgage-Backed Securities — 919,129 — 919,129 Total Investment Securities Available-for-Sale 61,271 2,227,919 — 2,289,190 Loans Held for Sale — 5,136 — 5,136 Mortgage Servicing Rights — — 2,604 2,604 Other Assets 18,794 — — 18,794 Derivatives 1 — 101 16,414 16,515 Total Assets Measured at Fair Value on a $ 80,065 $ 2,233,156 $ 19,018 $ 2,332,239 Liabilities: Derivatives 1 $ — $ 459 $ 16,296 $ 16,755 Total Liabilities Measured at Fair Value on a $ — $ 459 $ 16,296 $ 16,755 1 The fair value of each class of derivatives is shown in Note 11 to the Consolidated Financial Statements.

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 September 30, 2015 and December 31, 2014 , 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 Sept. 30, Dec. 31, Sept. 30, Dec. 31, Mortgage Servicing Rights Discounted Cash Flow Constant Prepayment Rate 1 10.01 % 11.62 % $ 26,491 $ 25,441 Discount Rate 2 9.71 % 10.61 % Net Derivative Assets and Liabilities: Interest Rate Lock Commitments Pricing Model Closing Ratio 92.32 % 93.85 % $ 437 $ 152 Interest Rate Swap Agreements Discounted Cash Flow Credit Factor 0.21 % 0.21 % $ (35 ) $ (34 ) 1 Represents annualized loan repayment rate assumption. 2 Derived from multiple interest rate scenarios that incorporate a spread to the London Interbank Offered Rate swap 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 applying the model to historical prepayment data. The fair value and constant prepayment rate are also compared to forward-looking estimates to assess reasonableness. 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 our secondary marketing system using historical data and the ratio is periodically reviewed by the Company’s Secondary Marketing Department of the Mortgage Banking Division 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 September 30, 2015 and December 31, 2014 . (dollars in thousands) Fair Value Hierarchy Net Carrying Amount Valuation Allowance September 30, 2015 Mortgage Servicing Rights - amortization method Level 3 $ 21,229 $ 21 Foreclosed Real Estate Level 3 1,392 — Other Assets - Equipment Held for Sale Level 3 4,657 9,453 December 31, 2014 Mortgage Servicing Rights - amortization method Level 3 $ 22,091 $ 57 Foreclosed Real Estate Level 3 2,311 89 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. The December 31, 2014 valuation allowance for the Company's foreclosed real estate related to one commercial property. This property was sold in the third quarter of 2015. The Company's equipment held for sale represents six aircraft that were previously on lease agreements. An impairment charge of $9.5 million (included in other noninterest expense in the Company's consolidated statements of income) was recorded in the third quarter of 2015 to reduce the carrying value to estimated fair value less cost to sell based on recent appraisals, market conditions, and management judgment. Due to the use of significant unobservable inputs combined with significant management judgment regarding the fair value of the six aircraft, the carrying value is deemed a Level 3 measurement. For segment reporting (see Note 9 to the Consolidated Financial Statements), the carrying value is included in the Commercial Banking segment. As appraisals on foreclosed real estate and equipment held for sale are not necessarily completed on the period end dates presented in the table above, the fair value information presented may not reflect the actual fair value as of September 30, 2015 and December 31, 2014 . Fair Value Option The Company elected the fair value option for all residential mortgage loans held for sale originated on or after October 1, 2011. 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 September 30, 2015 and December 31, 2014 . (dollars in thousands) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Unpaid Principal September 30, 2015 Loans Held for Sale $ 3,222 $ 3,009 $ 213 December 31, 2014 Loans Held for Sale $ 5,136 $ 4,740 $ 396 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 nine months ended September 30, 2015 and 2014 , 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 assumptions used below are expected to approximate those that market participants would use in valuing these financial instruments. Investment Securities Held-to-Maturity The fair value of the Company’s investment securities held-to-maturity was primarily measured using information from a third-party pricing service. 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. If quoted prices were not available, fair values were estimated primarily by obtaining quoted prices for similar assets in active markets or through the use of pricing models. In cases where there may be limited or less transparent information provided by the Company’s third-party pricing service, fair value may be estimated by the use of secondary pricing services or through the use of non-binding third-party broker quotes. Loans The fair value of the Company’s loans was estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans were first segregated by type such as commercial, real estate, and consumer, and were then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Time Deposits The fair values of the Company’s time deposits were estimated using discounted cash flow analyses. The discount rates used were based on rates currently offered for deposits with similar remaining maturities. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Securities Sold Under Agreements to Repurchase The fair value of the Company’s securities sold under agreements to repurchase was calculated using discounted cash flow analyses, applying discount rates currently offered for new agreements with similar remaining maturities and considering the Company’s non-performance risk. Other Debt The fair value of the Company’s other debt was calculated using a discounted cash flow approach and applying discount rates currently offered for new notes with similar remaining maturities and considering the Company’s non-performance risk. The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments not recorded at fair value on a recurring basis as of September 30, 2015 and December 31, 2014 . 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.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements of the Company 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. In the opinion of management, the consolidated financial statements reflect normal recurring adjustments necessary for a fair presentation of the results for the interim periods. Certain prior period information has been reclassified to conform to the current period presentation. These statements 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, 2014 . Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 .
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.
Accounting Standards Adopted in the Current Year or Pending Adoption	Accounting Standards Adopted in 2015 In January 2014, the FASB issued ASU No. 2014-01, "Accounting for Investments in Qualified Affordable Housing Projects." 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. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. This new guidance also requires new disclosures for all investors in these projects (see Note 5 to the Consolidated Financial Statements). The Company adopted ASU No. 2014-01 effective January 1, 2015. Upon adoption, the guidance must be applied retrospectively to all periods presented. However, entities that used the effective yield method to account for investments in these projects before adoption may continue to do so for these pre-existing investments. Prior to adoption of ASU No. 2014-01, the Company accounted for such investments using the effective yield method and continued to do so for these pre-existing investments after adopting ASU No. 2014-01. The Company expects future investments to meet the criteria required for the proportional amortization method and plans to make such an accounting policy election. There were no new investments being amortized since the adoption of ASU No. 2014-01 on January 1, 2015, and therefore, the adoption of ASU No. 2014-01 has not had a material impact on the Company's Consolidated Financial Statements. In January 2014, the FASB issued ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both: (1) the amount of foreclosed residential real estate property held by the creditor; and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The Company adopted ASU No. 2014-04 effective January 1, 2015. The adoption of ASU No. 2014-04 did not have a material impact on the Company's Consolidated Financial Statements. In June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." The new guidance aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. The amendments in the ASU require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The amendments in the ASU also require expanded disclosures, effective June 30, 2015, about the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings (see Note 6 to the Consolidated Financial Statements). The Company adopted the amendments in this ASU effective January 1, 2015. As of September 30, 2015 , all of the Company's repurchase agreements were typical in nature (i.e., not repurchase-to-maturity transactions or repurchase agreements executed as a repurchase financing) and are accounted for as secured borrowings. As such, the adoption of ASU No. 2014-11 did not have a material impact on the Company's Consolidated Financial Statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718, Compensation - Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. However, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. Entities may apply the amendments in this ASU either: (1) prospectively to all awards granted or modified after the effective date; or (2) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company adopted ASU No. 2014-12 effective January 1, 2015. As of September 30, 2015 , the Company did not have any share-based payment awards that included performance targets that could be achieved after the requisite service period. As such, the adoption of ASU No. 2014-12 did not have a material impact on the Company's Consolidated Financial Statements. In August 2014, the FASB issued ASU No. 2014-14, “Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The objective of this guidance is to reduce diversity in practice related to how creditors classify government-guaranteed mortgage loans, including FHA and VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure; (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The Company adopted ASU No. 2014-14 effective January 1, 2015. The adoption of ASU No. 2014-14 did not have a material impact on the Company's Consolidated Financial Statements. Accounting Standards Pending Adoption In May 2014, the FASB and the International Accounting Standards Board (the "IASB") jointly issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP and International Financial Reporting Standards ("IFRS"). Previous revenue recognition guidance in GAAP comprised broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes resulted in different accounting for economically similar transactions. In contrast, IFRS provided limited revenue recognition guidance and, consequently, could be difficult to apply to complex transactions. Accordingly, the FASB and the IASB initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosure requirements; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. To meet those objectives, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." 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. In doing so, companies generally will be required to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard was initially effective for public entities for interim and annual reporting periods beginning after December 15, 2016; early adoption is not permitted. However, in August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers - Deferral of the Effective Date" which defers the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09 and will be closely monitoring developments and additional guidance to determine the potential impact the new standard will have on the Company's Consolidated Financial Statements. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidation Analysis.” This ASU affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU No. 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015. The adoption of ASU No. 2015-02 is not expected to have a material impact on the Company's Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU No. 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company’s current method of accounting for fees paid in a cloud computing arrangement is consistent with the accounting guidance provided by ASU No. 2015-05. Therefore, the adoption of ASU No. 2015-05 is not expected to have a material impact on the Company's Consolidated Financial Statements.

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 September 30, 2015 and December 31, 2014 . 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.
