Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements of Central Pacific Financial Corp. and Subsidiaries (herein referred to as the "Company," "we," "us" or "our") 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, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements and notes should be read in conjunction with the Company's consolidated financial statements and notes thereto filed on Form 10-K, as amended by our Form 10-K/A for the fiscal year ended December 31, 2017 . In the opinion of management, all adjustments necessary for a fair presentation have been made and include all normal recurring adjustments. Interim results of operations are not necessarily indicative of results to be expected for the year. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In December 2015, we acquired a 50% ownership interest in a mortgage loan origination and brokerage company, One Hawaii HomeLoans, LLC. The bank concluded that the investment meets the consolidation requirements under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, "Consolidation." The bank concluded that the entity meets the definition of a variable interest entity and that we are the primary beneficiary of the variable interest entity. Accordingly, the investment was consolidated into our financial statements. One Hawaii HomeLoans, LLC was terminated in 2017, and final payment of taxes and distributions to members were made in March 2018. We have 50% ownership interests in three other mortgage loan origination and brokerage companies which are accounted for using the equity method and are included in investment in unconsolidated subsidiaries: Gentry HomeLoans, LLC, Haseko HomeLoans, LLC and Island Pacific HomeLoans, LLC. We also had 50% ownership interest in one additional mortgage loan origination and brokerage company, Pacific Access Mortgage, LLC, which was also accounted for using the equity method and was included in investment in unconsolidated subsidiaries. Pacific Access Mortgage, LLC was terminated in 2017, and final payment of taxes and distributions to members were made in March 2018. We also have non-controlling equity investments in affiliates that are accounted for under the cost method and are included in investment in unconsolidated subsidiaries. Our investments in unconsolidated subsidiaries accounted for under the equity and cost methods were $0.1 million and $6.3 million , respectively, at March 31, 2018 and $0.6 million and $6.5 million , respectively, at December 31, 2017 . Our policy for determining impairment of these investments includes an evaluation of whether a loss in value of an investment is other than temporary. Evidence of a loss in value includes absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment. We perform impairment tests whenever indicators of impairment are present. If the value of an investment declines and it is considered other than temporary, the investment is written down to its respective fair value in the period in which this determination is made. The Company sponsors the Central Pacific Bank Foundation, which is not consolidated in the Company's financial statements. Reclassifications The Company's equity investment securities in the prior year have been reclassified from available-for-sale debt securities to conform to the current year's presentation. The reclassification had no impact on the Company's reported net income or shareholders' equity.

RECENT ACCOUNTING PRONOUNCEMENT

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted in 2018 In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU replaces most existing revenue recognition guidance in GAAP. ASU 2014-09 was initially effective for the Company's reporting period beginning on January 1, 2017. However, in August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" which deferred the effective date by one year. For financial reporting purposes, the standard allows for either a full retrospective or modified retrospective adoption. The FASB has also issued additional updates to provide further clarification to specific implementation issues associated with ASU 2014-09. These updates include ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations," ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," and ASU 2016-20 "Technical Corrections and Improvements to Topic 606." Our revenue is comprised of net interest income on financial assets and financial liabilities, which is our main source of income, and other operating income. The scope of ASU 2014-09 explicitly excludes net interest income, as well as other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives. With respect to other operating income, the Company conducted a comprehensive scoping exercise to determine the revenue streams that are in scope of the guidance. This included reviewing the contracts potentially impacted by the standard in revenue streams such as deposit-related fees, merchant fees, bank card fees, interchange fees, commissions income, trust and asset management fees, foreign exchange fees, and loan placement fees. We adopted ASU 2014-09 and all subsequent amendments to the standard beginning January 1, 2018 under the modified retrospective approach. Based on our analysis, the standard required us to change how we recognize certain recurring revenue streams on a gross versus net basis. This resulted in an increase in other service charges and fees totaling $0.1 million during the first quarter of 2018 and the resultant increase in other operating expense-other for the same amount. These changes did not have an impact to our net income; as such a cumulative effect adjustment to opening accumulated deficit was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be recorded in accordance with legacy GAAP. Refer to Note 12 - Revenue from Contracts with Customers for further discussion on the Company's accounting policies for revenue sources within the scope of Accounting Standards Codification ("ASC") 606. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Liabilities . " The amendments in ASU 2016-01 made targeted improvements to GAAP as follows: 1) required equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, 2) simplified the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, 3) eliminated the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities, 4) eliminated the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, 5) required public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, 6) required an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, 7) required separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and 8) clarified that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company adopted ASU 2016-01 beginning January 1, 2018, which resulted in a reclassification of the Company's equity investment securities portfolio of $0.8 million and $0.8 million as of March 31, 2018 and December 31, 2017 , respectively, from available-for-sale debt securities to equity securities on the Company's consolidated balance sheets. Changes in fair value are recognized in net income. In addition, during the first quarter of 2018, the Company recorded a cumulative effect adjustment which increased opening retained earnings (or reduced opening accumulated deficit) and decreased accumulated other comprehensive income (loss) ("AOCI") by $0.1 million related to the unrealized gains on the equity investment securities portfolio and changes in the fair value of the equity investment securities portfolio were recognized in net income. The Company also engaged a third-party consultant, who used a refined calculation to determine the fair value of our loans held for investment portfolio using the exit price notion, which is included in our fair value disclosures in Note 18 - Fair Value of Financial Assets and Liabilities . The refined calculation did not have a material impact on our fair value disclosures. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 provided guidance on eight statement of cash flow classification issues and was intended to reduce the current and future diversity in practice described in the amendments. Current GAAP is either unclear or does not include specific guidance on the eight statement of cash flow classification issues included in ASU 2016-15. The Company adopted ASU 2016-15 effective January 1, 2018. The amendments in ASU 2016-15 did not impact the Company's financial statements as our current practice was consistent with the update. In March 2017, the FASB issued ASU 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost." ASU 2017-07 requires an entity to present the service cost component of the net periodic benefit cost in the same line item or items in the statement of income as other employee compensation costs arising from services rendered by the pertinent employees during the period. In addition, only the service cost component is eligible for capitalization. The other components of net benefit costs should be presented in the statement of income separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item is used to present the other components, that line item shall be described appropriately. The line items used in the income statement to present the components other than the service cost component shall be disclosed if a Company elects to not present them in a separate line item. The Company adopted ASU 2017-07 effective January 1, 2018. The amendments in ASU 2017-07 did not impact the Company's financial statements. In March 2017, the FASB issued ASU 2017-08, "Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. ASU 2017-08 does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company adopted ASU 2017-08 effective January 1, 2018. The amendments in ASU 2017-08 did not impact the Company's financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification." ASU 2017-09 was issued to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, to a change to the terms or conditions of a share-based payment award. Diversity in practice has arisen in part because some entities apply modification accounting under Topic 718 for modifications to terms and conditions that they consider substantive, but do not when they conclude that particular modifications are not substantive. Others apply modification accounting for any change to an award, except for changes that they consider purely administrative in nature. Still others apply modification accounting when a change to an award changes the fair value, the vesting, or the classification of the award. In practice, it appears that the evaluation of a change in fair value, vesting, or classification may be used to evaluate whether a change is substantive. ASU 2017-09 includes guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The Company adopted ASU 2017-09 effective January 1, 2018. The amendments in ASU 2017-09 did not impact the Company's financial statements as the Company has not historically had any scope modifications and has no plans to do so in the near future. In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." ASU 2018-02 was issued to address certain stranded tax effects in AOCI as a result of H.R.1., commonly referred to as the Tax Cuts and Jobs Act ("Tax Reform"). ASU 2018-02 provides companies the option to reclassify stranded tax effects within AOCI to retained earnings (or accumulated deficit) in each period in which the effect of the change from the newly enacted corporate tax rate is recorded. The amount of the reclassification is calculated on the basis of the difference between the historical and newly enacted tax rates for deferred tax assets and liabilities related to items within AOCI. ASU 2018-02 requires companies to disclose its accounting policy related to releasing income tax effects from accumulated other comprehensive income, whether it has elected to reclassify the stranded tax effects, and information about the other income tax effects that are reclassified. Although ASU 2018-02 was effective for the Company's reporting period beginning on January 1, 2019, the Company elected to early adopt the standard effective January 1, 2018. As a result, the Company recorded cumulative effect adjustments which increased opening retained earnings (or reduced opening accumulated deficit) and decreased AOCI for the stranded tax effects related to the Company's defined benefit pension and supplemental retirement plan obligations and the unrealized gain on the Company's investment securities portfolio by $1.4 million and $0.5 million , respectively.

Investment securities are evaluated for OTTI on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value below amortized cost is other-than-temporary. In conducting this assessment, we evaluate a number of factors including, but not limited to: • The length of time and the extent to which fair value has been less than the amortized cost basis; • Adverse conditions specifically related to the security, an industry, or a geographic area; • The historical and implied volatility of the fair value of the security; • The payment structure of the debt security and the likelihood of the issuer being able to make payments; • Failure of the issuer to make scheduled interest or principal payments; • Any rating changes by a rating agency; and • Recoveries or additional declines in fair value subsequent to the balance sheet date. The term "other-than-temporary" is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Once a decline in value is determined to be other-than-temporary, the value of the security is reduced and a corresponding charge to earnings is recognized for anticipated credit losses. Because we have no intent to sell securities in an unrealized loss position and it is not more likely than not that we will be required to sell such securities before recovery of its amortized cost basis, we do not consider our investments to be other-than-temporarily impaired.

Aging Analysis of Accruing and Non-Accruing Loans and Leases For all loan types, the Company determines delinquency status by considering the number of days full payments required by the contractual terms of the loan are past due. The following tables present by class, the aging of the recorded investment in past due loans and leases as of March 31, 2018 and December 31, 2017 : (dollars in thousands) Accruing Accruing Accruing Nonaccrual Total Loans and Total March 31, 2018 Commercial, financial & agricultural $ 1,076 $ 428 $ — $ — $ 1,504 $ 514,976 $ 516,480 Real estate: Construction — — — — — 61,653 61,653 Residential mortgage 4,129 381 — 2,184 6,694 1,344,794 1,351,488 Home equity 49 175 — 659 883 424,626 425,509 Commercial mortgage — — — — — 1,005,828 1,005,828 Consumer 2,149 839 417 — 3,405 451,498 454,903 Leases — — — — — 285 285 Total $ 7,403 $ 1,823 $ 417 $ 2,843 $ 12,486 $ 3,803,660 $ 3,816,146 (dollars in thousands) Accruing Accruing Accruing Nonaccrual Total Loans and Total December 31, 2017 Commercial, financial & agricultural $ 410 $ 355 $ — $ — $ 765 $ 503,254 $ 504,019 Real estate: Construction — — — — — 64,240 64,240 Residential mortgage 4,037 2,127 49 2,280 8,493 1,332,728 1,341,221 Home equity 105 264 — 416 785 411,445 412,230 Commercial mortgage — — — 79 79 977,718 977,797 Consumer 2,126 1,056 515 — 3,697 467,049 470,746 Leases — — — — — 362 362 Total $ 6,678 $ 3,802 $ 564 $ 2,775 $ 13,819 $ 3,756,796 $ 3,770,615 Modifications Troubled debt restructurings ("TDRs") included in nonperforming assets at March 31, 2018 consisted of six Hawaii residential mortgage loans with a combined principal balance of $0.6 million . Concessions made to the original contractual terms of these loans consisted primarily of the deferral of interest and/or principal payments due to deterioration in the borrowers' financial condition. The principal balances on these TDRs had matured and/or were in default at the time of restructure, and we have no commitments to lend additional funds to any of these borrowers. There were $12.4 million of TDRs still accruing interest at March 31, 2018 , none of which were more than 90 days delinquent. At December 31, 2017 , there were $12.6 million of TDRs still accruing interest, none of which were more than 90 days delinquent. Some loans modified in a TDR may already be on nonaccrual status and partial charge-offs may have already been taken against the outstanding loan balance. Thus, these loans have already been identified as impaired and have already been evaluated under the Company's allowance for loan and lease losses (the "Allowance") methodology. Loans that were not on nonaccrual status when modified in a TDR may have the financial effect of increasing the specific allowance associated with the loan. The loans modified in a TDR did not have a material effect on our provision for loan and lease losses (the "Provision") and the Allowance during the three months ended March 31, 2018 . The following table presents by class, information related to loans modified in a TDR during the period presented. There were no loans modified in a TDR during the three months ended March 31, 2018 . (dollars in thousands) Number of Recorded Increase in the Three Months Ended March 31, 2017 Commercial, financial & agricultural 1 $ 659 $ — Total 1 $ 659 $ — No loans were modified as a TDR within the previous twelve months that subsequently defaulted during the three months ended March 31, 2018 and 2017 . Credit Quality Indicators The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans and leases individually by classifying the loans and leases by credit risk. This analysis includes non-homogeneous loans and leases, such as commercial and commercial real estate loans. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Special Mention. Loans and leases classified as special mention, while still adequately protected by the borrower's capital adequacy and payment capability, exhibit distinct weakening trends and/or elevated levels of exposure to external conditions. If left unchecked or uncorrected, these potential weaknesses may result in deteriorated prospects of repayment. These exposures require management's close attention so as to avoid becoming undue or unwarranted credit exposures. Substandard. Loans and leases classified as substandard are inadequately protected by the borrower's current financial condition and payment capability or of the collateral pledged, if any. Loans and leases so classified have a well-defined weakness or weaknesses that jeopardize the orderly repayment of debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. Doubtful. Loans and leases classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or orderly repayment in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. Possibility of loss is extremely high, but because of certain important and reasonably specific factors that may work to the advantage and strengthening of the exposure, its classification as an estimated loss is deferred until its more exact status may be determined. Loss. Loans and leases classified as loss are considered to be non-collectible and of such little value that their continuance as bankable assets is not warranted. This does not mean the loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. Losses are taken in the period in which they surface as uncollectible. Loans and leases not meeting the criteria above are considered to be pass-rated. The following table presents by class and credit indicator, the recorded investment in the Company's loans and leases as of March 31, 2018 and December 31, 2017 : (dollars in thousands) Pass Special Substandard Loss Subtotal Net Total March 31, 2018 Commercial, financial & agricultural $ 488,490 $ 9,044 $ 18,626 $ — $ 516,160 $ 320 $ 516,480 Real estate: Construction 53,167 8,879 — — 62,046 (393 ) 61,653 Residential mortgage 1,345,269 — 2,286 — 1,347,555 3,933 1,351,488 Home equity 424,851 — 659 — 425,510 (1 ) 425,509 Commercial mortgage 988,309 8,597 10,390 — 1,007,296 (1,468 ) 1,005,828 Consumer 454,549 — 191 227 454,967 (64 ) 454,903 Leases 285 — — — 285 — 285 Total $ 3,754,920 $ 26,520 $ 32,152 $ 227 $ 3,813,819 $ 2,327 $ 3,816,146 (dollars in thousands) Pass Special Substandard Loss Subtotal Net Total December 31, 2017 Commercial, financial & agricultural $ 474,995 $ 7,543 $ 21,200 $ — $ 503,738 $ 281 $ 504,019 Real estate: Construction 55,646 8,879 — — 64,525 (285 ) 64,240 Residential mortgage 1,334,760 — 2,433 — 1,337,193 4,028 1,341,221 Home equity 411,814 — 416 — 412,230 — 412,230 Commercial mortgage 955,865 12,735 10,639 — 979,239 (1,442 ) 977,797 Consumer 470,243 — 305 271 470,819 (73 ) 470,746 Leases 362 — — — 362 — 362 Total $ 3,703,685 $ 29,157 $ 34,993 $ 271 $ 3,768,106 $ 2,509 $ 3,770,615 In accordance with applicable Interagency Guidance issued by our primary bank regulators, we define subprime borrowers as typically having weakened credit histories that include payment delinquencies and possibly more severe problems such as charge-offs, judgments, and bankruptcies. They may also display reduced repayment capacity as measured by credit scores, debt-to-income ratios, or other criteria that may encompass borrowers with incomplete credit histories. Subprime loans are loans to borrowers displaying one or more of these characteristics at the time of origination or purchase. Such loans have a higher risk of default than loans to prime borrowers. At March 31, 2018 and December 31, 2017 , we did not have any loans that we considered to be subprime.

Transfers and Servicing [Abstract]
SECURITIZATIONS	6. SECURITIZATIONS In prior years, we securitized certain residential mortgage loans with a U.S. Government sponsored entity and continue to service the residential mortgage loans. The servicing assets were recorded at their respective fair values at the time of securitization. All unsold mortgage-backed securities from prior securitizations were categorized as available for sale securities and were therefore recorded at their fair values of $1.3 million and $1.5 million at March 31, 2018 and December 31, 2017 , respectively. The fair values of these mortgage-backed securities were based on quoted prices of similar instruments in active markets. Unrealized gains of $0.1 million and $0.1 million on unsold mortgage-backed securities were recorded in AOCI at March 31, 2018 and December 31, 2017 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	9. DERIVATIVES We utilize various designated and undesignated derivative financial instruments to reduce our exposure to movements in interest rates including interest rate swaps, interest rate lock commitments and forward sale commitments. We measure all derivatives at fair value on our consolidated balance sheet. In each reporting period, we record the derivative instruments in other assets or other liabilities depending on whether the derivatives are in an asset or liability position. For derivative instruments that are designated as cash flow hedging instruments, we record the effective portion of the changes in the fair value of the derivative in AOCI, net of tax, until earnings are affected by the variability of cash flows of the hedged transaction. We immediately recognize the portion of the gain or loss in the fair value of the derivative that represents hedge ineffectiveness in current period earnings. For derivative instruments that are not designated as hedging instruments, changes in the fair value of the derivative are included in current period earnings. At March 31, 2018 , we were not party to any derivatives designated as part of a fair value or cash flow hedge. Interest Rate Lock and Forward Sale Commitments We enter into interest rate lock commitments on certain mortgage loans that are intended to be sold. To manage interest rate risk on interest rate lock commitments, we also enter into forward loan sale commitments. The interest rate locks and forward loan sale commitments are accounted for as undesignated derivatives and are recorded at their respective fair values in other assets or other liabilities, with changes in fair value recorded in current period earnings. These instruments serve to reduce our exposure to movements in interest rates. At March 31, 2018 , we were a party to interest rate lock and forward sale commitments on $3.1 million and $9.2 million of mortgage loans, respectively. The following table presents the location of all assets and liabilities associated with our derivative instruments within the consolidated balance sheets: Derivatives Financial Instruments Not Designated as Hedging Instruments Asset Derivatives Liability Derivatives Fair Value at Fair Value at (dollars in thousands) Balance Sheet Location March 31, December 31, March 31, December 31, Interest rate lock and forward sale commitments Other assets / other liabilities $ 28 $ 35 $ 21 $ 49 The following table presents the impact of derivative instruments and their location within the consolidated statements of income: Derivatives Financial Instruments Location of Gain (Loss) Amount of Gain (Loss) (dollars in thousands) Three Months Ended March 31, 2018 Interest rate lock and forward sale commitments Mortgage banking income $ 21 Loans held for sale Other income (7 ) Three Months Ended March 31, 2017 Interest rate lock and forward sale commitments Mortgage banking income (207 )

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	12. REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers" , establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts to provide goods or services to its customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services. Revenue is recognized as performance obligations are satisfied. The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Our principal source of revenue is derived from interest income on financial instruments, such as our loan and investment securities portfolios, as well as revenue related to our mortgage banking activities. These revenue-generating transactions are out of scope of ASC 606, but are subject to other GAAP and discussed elsewhere within our disclosures. We also generate other revenue in connection with our broad range of banking products and financial services. Descriptions of our other revenue-generating activities that are within the scope of ASC 606, which are presented in our consolidated statements of income as components of other operating income are as follows: Service charges on deposit accounts Revenue from service charges on deposit accounts includes general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as stop payment fees). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Other Service Charges and Fees Revenue from other service charges and fees includes cards and payments income, safe deposit rental income and other service charges, commissions and fees. Cards and payments income includes interchange fees from debit cards processed through card association networks, merchant services, and other card related services. Interchange rates are generally set by the credit card associations and based on purchase volumes and other factors. Interchange fees are recognized as transactions occur. Interchange expenses related to cards and payments income are presented gross in other operating expense. Merchant services income represents account management fees and transaction fees charged to merchants for the processing of card association network transactions. Merchant services revenue is recognized as transactions occur, or as services are performed. Other service charges, commissions and fees include automated teller machines ("ATM") surcharge and interchange fees, bill payment fees, cashier’s check and money order fees, wire transfer fees, loan brokerage fees, and commissions on sales of insurance, broker-dealer products, letters of credit, and travelers’ checks. Revenue from these fees and commissions is recorded in a manner that reflects the timing of when transactions occur, and as services are provided. Based on the nature of the commission agreement with the broker-dealer and each insurance provider, we may recognize revenue from broker-dealer and insurance commissions over time or at a point-in-time as our performance obligation is satisfied. Income from Fiduciary Activities Income from fiduciary activities includes fees from wealth management, trust, custodial and escrow services provided to individual and institutional customers. Revenue is generally recognized monthly based on a minimum annual fee and/or the market value of assets in custody. Additional fees are recognized for transactional activity. Revenue from trade execution and brokerage services is earned through commissions from trade execution on behalf of clients. Revenue from these transactions is recognized at the trade date. Any ongoing service fees are recognized on a monthly basis as services are performed. Loan Placement Fees Loan placement fees primarily represent revenues earned by the Company for loan placement and underwriting. Revenues for these services are recorded at a point-in-time, upon completion of a contractually identified transaction, or when an advisory opinion is provided. The following presents the Company's other operating income, segregated by revenue streams that are in-scope and out-of-scope of ASC 606 for the three months ended March 31, 2018 and 2017 .

Equity [Abstract]
EQUITY	11. EQUITY As a Hawaii state-chartered bank, Central Pacific Bank may only pay dividends to the extent it has retained earnings as defined under Hawaii banking law ("Statutory Retained Earnings"), which differs from GAAP retained earnings. As of March 31, 2018 , the bank had Statutory Retained Earnings of $86.9 million . Dividends are payable at the discretion of the Board of Directors and there can be no assurance that the Board of Directors will continue to pay dividends at the same rate, or at all, in the future. Our ability to pay cash dividends to our shareholders is subject to restrictions under federal and Hawaii law, including restrictions imposed by the FRB and covenants set forth in various agreements we are a party to, including covenants set forth in our subordinated debentures. In January 2016, the Board of Directors authorized the repurchase of up to $30.0 million of the Company's common stock from time to time in the open market or in privately negotiated transactions, pursuant to a newly authorized share repurchase program (the "2016 Repurchase Plan"), which superseded in its entirety the repurchase plan that was previously approved by the Board of Directors. In January 2017, the Board of Directors authorized the repurchase of up to $30.0 million of the Company's common stock from time to time in the open market or in privately negotiated transactions, pursuant to a newly authorized share repurchase program (the "2017 Repurchase Plan"). The 2017 Repurchase Plan replaced and superseded in its entirety the 2016 Repurchase Plan. In January 2017, prior to the 2017 Repurchase Plan being approved, 1,750 shares of common stock, at a cost of $0.1 million , were repurchased under the 2016 Repurchase Plan. In November 2017, the Board of Directors authorized an increase in the share repurchase program authority by an additional $50.0 million (known henceforth as the "Repurchase Plan"). This amount is in addition to the $30.0 million in planned repurchases authorized in January 2017. There is no expiration date on the Repurchase Plan. In the year ended December 31, 2017, 864,483 shares of common stock, at a cost of $26.6 million , excluding fees and expenses, were repurchased under the 2016 Repurchase Plan and the Repurchase Plan combined. In the three months ended March 31, 2018 , a total of 344,362 shares of common stock, at a cost of $10.1 million , were repurchased under the Repurchase Plan. A total of $43.4 million remained available for repurchase under the Repurchase Plan as of March 31, 2018 .

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES	18. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES Disclosures about Fair Value of Financial Instruments Fair value estimates, methods and assumptions are set forth below for our financial instruments. Short-Term Financial Instruments The carrying values of short-term financial instruments are deemed to approximate fair values. Such instruments are considered readily convertible to cash and include cash and due from banks, interest-bearing deposits in other banks, accrued interest receivable, short-term borrowings, and accrued interest payable. Investment Securities The fair value of investment securities is based on market price quotations received from third-party pricing services. The third-party pricing services utilize pricing models supported with timely market data information. Where quoted market prices are not available, fair values are based on quoted market prices of comparable securities. Loans Fair values of loans are estimated based on discounted cash flows of portfolios of loans with similar financial characteristics including the type of loan, interest terms and repayment history. Fair values are calculated by discounting scheduled cash flows through estimated maturities using estimated market discount rates. Estimated market discount rates are reflective of credit and interest rate risks inherent in the Company's various loan types and are derived from available market information, as well as specific borrower information. In accordance with ASU 2016-01, the fair value of loans as of March 31, 2018 are based on the notion of exit price. The fair value of loans as of December 31, 2017 was measured using an entry price notion. Loans Held for Sale The fair value of loans classified as held for sale are generally based upon quoted prices for similar assets in active markets, acceptance of firm offer letters with agreed upon purchase prices, discounted cash flow models that take into account market observable assumptions, or independent appraisals of the underlying collateral securing the loans. We report the fair values of Hawaii and U.S. Mainland construction and commercial real estate loans, if any, net of applicable selling costs on our consolidated balance sheets. Mortgage Servicing Rights The initial fair value of the servicing right is calculated by a discounted cash flow model prepared by a third-party service provider based on market value assumptions at the time of origination. We assess the servicing right for impairment using current market value assumptions at each reporting period. Critical assumptions used in the discounted cash flow model include mortgage prepayment speeds, discount rates, costs to service, and ancillary income. Variations in our assumptions could materially affect the estimated fair values. Changes to our assumptions are made when current trends and market data indicate that new trends have developed. Current market value assumptions based on loan product types (fixed rate, adjustable rate and balloon loans) include average discount rates and prepayment speeds. Many of these assumptions are subjective and require a high level of management judgment. Our mortgage servicing rights portfolio and valuation assumptions are periodically reviewed by management. Federal Home Loan Bank Stock The equity investment in common stock of the FHLB, which is redeemable for cash at par value, is reported at its par value. Deposit Liabilities The fair values of deposits with no stated maturity, such as noninterest-bearing demand deposits and interest-bearing demand and savings accounts, are equal to the amount payable on demand. The fair value of time deposits is estimated using discounted cash flow analyses. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Long-Term Debt The fair value of our long-term debt is estimated by discounting scheduled cash flows over the contractual borrowing period at the estimated market rate for similar borrowing arrangements. Off-Balance Sheet Financial Instruments The fair values of off-balance sheet financial instruments are estimated based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties, current settlement values or quoted market prices of comparable instruments. For derivative financial instruments, the fair values are based upon current market values, if available. If there are no relevant comparables, fair values are based on pricing models using current assumptions for interest rate swaps and options. Limitations Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time our entire holdings of a particular financial instrument. Because no market exists for a significant portion of our financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of future business and the value of assets and liabilities that are not considered financial instruments. For example, significant assets and liabilities that are not considered financial assets or liabilities include deferred tax assets, premises and equipment and intangible assets.

A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level 3 — Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of discounted cash flow models and similar techniques that requires the use of significant judgment or estimation. We base our fair values on the price that we would expect to receive if an asset were sold or pay to transfer a liability in an orderly transaction between market participants at the measurement date. We also maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. We use fair value measurements to record adjustments to certain financial assets and liabilities and to determine fair value disclosures. Available for sale securities and derivatives are recorded at fair value on a recurring basis. From time to time, we may be required to record other financial assets at fair value on a nonrecurring basis such as loans held for sale, impaired loans, mortgage servicing rights, and other real estate owned. These nonrecurring fair value adjustments typically involve application of the lower of cost or fair value accounting or write-downs of individual assets. There were no transfers of financial assets and liabilities between Level 1 and Level 2 of the fair value hierarchy during the three months ended March 31, 2018 . Also, there were no transfers of financial assets and liabilities into or out of Level 3 of the fair value hierarchy during the three months ended March 31, 2018 . The following tables present the fair value of assets and liabilities measured on a recurring basis as of March 31, 2018 and December 31, 2017 : Fair Value at Reporting Date Using (dollars in thousands) Fair Value Quoted Significant Significant March 31, 2018 Available-for-sale securities: Debt securities: States and political subdivisions $ 177,221 $ — $ 165,683 $ 11,538 Corporate securities 68,058 — 68,058 — U.S. Treasury obligations and direct obligations of U.S Government agencies 37,153 — 37,153 — Mortgage-backed securities: Residential - U.S. Government sponsored entities 811,322 — 811,322 — Commercial - U.S. Government agencies and sponsored entities 53,457 — 53,457 — Residential - Non-government agencies 44,440 — 44,440 — Commercial - Non-government agencies 134,441 — 134,441 — Total available-for-sale securities 1,326,092 — 1,314,554 11,538 Equity securities 753 753 — — Derivatives: Interest rate lock and forward sale commitments 7 — 7 — Total $ 1,326,852 $ 753 $ 1,314,561 $ 11,538 Fair Value at Reporting Date Using (dollars in thousands) Fair Value Quoted Significant Significant December 31, 2017 Available-for-sale securities: Debt securities: States and political subdivisions $ 179,781 $ — $ 167,987 $ 11,794 Corporate securities 74,278 — 74,278 — U.S. Treasury obligations and direct obligations of U.S Government agencies 25,510 — 25,510 — Mortgage-backed securities: Residential - U.S. Government sponsored entities 800,683 — 800,683 — Commercial - U.S. Government agencies and sponsored entities 39,725 — 39,725 — Residential - Non-government agencies 46,763 — 46,763 — Commercial - Non-government agencies 137,326 — 137,326 — Total available-for-sale securities 1,304,066 — 1,292,272 11,794 Equity securities 825 825 — — Derivatives: Interest rate lock and forward sale commitments (14 ) — (14 ) — Total $ 1,304,877 $ 825 $ 1,292,258 $ 11,794 For the three months ended March 31, 2018 and 2017 , the changes in Level 3 assets and liabilities measured at fair value on a recurring basis are summarized as follows: (dollars in thousands) Available for Sale Balance at December 31, 2017 $ 11,794 Principal payments received (91 ) Unrealized net gain (loss) included in other comprehensive income (165 ) Balance at March 31, 2018 $ 11,538 Balance at December 31, 2016 $ 12,196 Principal payments received (89 ) Unrealized net gain (loss) included in other comprehensive income 34 Balance at March 31, 2017 $ 12,141 Within the states and political subdivisions available-for-sale debt securities category, the Company holds four mortgage revenue bonds issued by the City & County of Honolulu with an aggregate fair value of $11.5 million and $12.1 million at March 31, 2018 and March 31, 2017 , respectively. The Company estimates the fair value of its mortgage revenue bonds by using a discounted cash flow model to calculate the present value of estimated future principal and interest payments. The significant unobservable input used in the fair value measurement of the Company's mortgage revenue bonds is the weighted average discount rate. As of March 31, 2018 , the weighted average discount rate utilized was 5.02% , compared to 4.73% at March 31, 2017 and 4.81% at December 31, 2017 , which was derived by incorporating a credit spread over the FHLB Fixed-Rate Advance curve. Significant increases (decreases) in the weighted average discount rate could result in a significantly lower (higher) fair value measurement. The following table presents the fair value of assets measured on a nonrecurring basis and the level of valuation assumptions used to determine the respective fair values as of March 31, 2018 and December 31, 2017 : Fair Value Measurements Using (dollars in thousands) Fair Value Quoted Prices Significant Significant March 31, 2018 Impaired loans (1) $ 20,963 $ — $ 20,963 $ — Mortgage servicing rights 18,463 — — 18,463 Other real estate (2) 595 — 595 — December 31, 2017 Impaired loans (1) $ 21,280 $ — $ 21,280 $ — Mortgage servicing rights 17,161 — — 17,161 Other real estate (2) 851 — 851 — (1) Represents carrying value and related write-downs of loans for which adjustments are based on agreed upon purchase prices for the loans or the appraised value of the collateral. (2) Represents other real estate that is carried at the lower of carrying value or fair value less costs to sell. Fair value is generally based upon independent market prices or appraised values of the collateral. The significant unobservable inputs used in the fair value measurement of the Company's mortgage servicing rights are the weighted average discount rate and the forecasted constant prepayment rate. As of March 31, 2018 , the weighted average discount rate and the forecasted constant prepayment rate utilized were 9.5% and 14.2% , respectively, compared to 9.5% and 15.0% , respectively, as of March 31, 2017 and 9.5% and 15.96% , respectively, as of December 31, 2017 . Significant increases (decreases) in the weighted average discount rate and/or the forecasted constant prepayment rate could result in a significantly lower (higher) fair value measurement.

Segment Reporting [Abstract]
SEGMENT INFORMATION	19. SEGMENT INFORMATION We have the following three reportable segments: Banking Operations, Treasury and All Others. These segments are consistent with our internal functional reporting lines and are managed separately because each unit has different target markets, technological requirements, and specialized skills. The Banking Operations segment includes construction and real estate development lending, commercial lending, residential mortgage lending, indirect auto lending, trust services, retail brokerage services and our retail branch offices, which provide a full range of deposit and loan products, as well as various other banking services. The Treasury segment is responsible for managing the Company's investment securities portfolio and wholesale funding activities. The All Others segment consists of all activities not captured by the Banking Operations or Treasury segments described above and includes activities such as electronic banking, data processing and management of bank owned properties. The accounting policies of the segments are consistent with the Company's accounting policies that are described in Note 1 - Summary of Significant Accounting Policies to the consolidated financial statements in the Annual Report on Form 10-K, as amended by our Form 10-K/A for the year ended December 31, 2017 filed with the SEC. The majority of the Company's net income is derived from net interest income. Accordingly, management focuses primarily on net interest income, rather than gross interest income and expense amounts, in evaluating segment profitability. Intersegment net interest income (expense) was allocated to each segment based upon a funds transfer pricing process that assigns costs of funds to assets and earnings credits to liabilities based on market interest rates that reflect interest rate sensitivity and maturity characteristics. All administrative and overhead expenses are allocated to the segments at cost. Cash, investment securities, loans and leases and their related balances are allocated to the segment responsible for acquisition and maintenance of those assets. Segment assets also include all premises and equipment used directly in segment operations. Segment profits and assets are provided in the following table for the periods indicated.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited consolidated financial statements of Central Pacific Financial Corp. and Subsidiaries (herein referred to as the "Company," "we," "us" or "our") 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, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements and notes should be read in conjunction with the Company's consolidated financial statements and notes thereto filed on Form 10-K, as amended by our Form 10-K/A for the fiscal year ended December 31, 2017 . In the opinion of management, all adjustments necessary for a fair presentation have been made and include all normal recurring adjustments. Interim results of operations are not necessarily indicative of results to be expected for the year.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In December 2015, we acquired a 50% ownership interest in a mortgage loan origination and brokerage company, One Hawaii HomeLoans, LLC. The bank concluded that the investment meets the consolidation requirements under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, "Consolidation." The bank concluded that the entity meets the definition of a variable interest entity and that we are the primary beneficiary of the variable interest entity. Accordingly, the investment was consolidated into our financial statements. One Hawaii HomeLoans, LLC was terminated in 2017, and final payment of taxes and distributions to members were made in March 2018. We have 50% ownership interests in three other mortgage loan origination and brokerage companies which are accounted for using the equity method and are included in investment in unconsolidated subsidiaries: Gentry HomeLoans, LLC, Haseko HomeLoans, LLC and Island Pacific HomeLoans, LLC. We also had 50% ownership interest in one additional mortgage loan origination and brokerage company, Pacific Access Mortgage, LLC, which was also accounted for using the equity method and was included in investment in unconsolidated subsidiaries. Pacific Access Mortgage, LLC was terminated in 2017, and final payment of taxes and distributions to members were made in March 2018. We also have non-controlling equity investments in affiliates that are accounted for under the cost method and are included in investment in unconsolidated subsidiaries. Our investments in unconsolidated subsidiaries accounted for under the equity and cost methods were $0.1 million and $6.3 million , respectively, at March 31, 2018 and $0.6 million and $6.5 million , respectively, at December 31, 2017 . Our policy for determining impairment of these investments includes an evaluation of whether a loss in value of an investment is other than temporary. Evidence of a loss in value includes absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain an earnings capacity which would justify the carrying amount of the investment. We perform impairment tests whenever indicators of impairment are present. If the value of an investment declines and it is considered other than temporary, the investment is written down to its respective fair value in the period in which this determination is made. The Company sponsors the Central Pacific Bank Foundation, which is not consolidated in the Company's financial statements.
Reclassification, Policy [Policy Text Block]	Reclassifications The Company's equity investment securities in the prior year have been reclassified from available-for-sale debt securities to conform to the current year's presentation. The reclassification had no impact on the Company's reported net income or shareholders' equity.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted in 2018 In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU replaces most existing revenue recognition guidance in GAAP. ASU 2014-09 was initially effective for the Company's reporting period beginning on January 1, 2017. However, in August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" which deferred the effective date by one year. For financial reporting purposes, the standard allows for either a full retrospective or modified retrospective adoption. The FASB has also issued additional updates to provide further clarification to specific implementation issues associated with ASU 2014-09. These updates include ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations," ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," and ASU 2016-20 "Technical Corrections and Improvements to Topic 606." Our revenue is comprised of net interest income on financial assets and financial liabilities, which is our main source of income, and other operating income. The scope of ASU 2014-09 explicitly excludes net interest income, as well as other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives. With respect to other operating income, the Company conducted a comprehensive scoping exercise to determine the revenue streams that are in scope of the guidance. This included reviewing the contracts potentially impacted by the standard in revenue streams such as deposit-related fees, merchant fees, bank card fees, interchange fees, commissions income, trust and asset management fees, foreign exchange fees, and loan placement fees. We adopted ASU 2014-09 and all subsequent amendments to the standard beginning January 1, 2018 under the modified retrospective approach. Based on our analysis, the standard required us to change how we recognize certain recurring revenue streams on a gross versus net basis. This resulted in an increase in other service charges and fees totaling $0.1 million during the first quarter of 2018 and the resultant increase in other operating expense-other for the same amount. These changes did not have an impact to our net income; as such a cumulative effect adjustment to opening accumulated deficit was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be recorded in accordance with legacy GAAP. Refer to Note 12 - Revenue from Contracts with Customers for further discussion on the Company's accounting policies for revenue sources within the scope of Accounting Standards Codification ("ASC") 606. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Liabilities . " The amendments in ASU 2016-01 made targeted improvements to GAAP as follows: 1) required equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, 2) simplified the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, 3) eliminated the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities, 4) eliminated the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, 5) required public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, 6) required an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, 7) required separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and 8) clarified that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company adopted ASU 2016-01 beginning January 1, 2018, which resulted in a reclassification of the Company's equity investment securities portfolio of $0.8 million and $0.8 million as of March 31, 2018 and December 31, 2017 , respectively, from available-for-sale debt securities to equity securities on the Company's consolidated balance sheets. Changes in fair value are recognized in net income. In addition, during the first quarter of 2018, the Company recorded a cumulative effect adjustment which increased opening retained earnings (or reduced opening accumulated deficit) and decreased accumulated other comprehensive income (loss) ("AOCI") by $0.1 million related to the unrealized gains on the equity investment securities portfolio and changes in the fair value of the equity investment securities portfolio were recognized in net income. The Company also engaged a third-party consultant, who used a refined calculation to determine the fair value of our loans held for investment portfolio using the exit price notion, which is included in our fair value disclosures in Note 18 - Fair Value of Financial Assets and Liabilities . The refined calculation did not have a material impact on our fair value disclosures. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 provided guidance on eight statement of cash flow classification issues and was intended to reduce the current and future diversity in practice described in the amendments. Current GAAP is either unclear or does not include specific guidance on the eight statement of cash flow classification issues included in ASU 2016-15. The Company adopted ASU 2016-15 effective January 1, 2018. The amendments in ASU 2016-15 did not impact the Company's financial statements as our current practice was consistent with the update. In March 2017, the FASB issued ASU 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost." ASU 2017-07 requires an entity to present the service cost component of the net periodic benefit cost in the same line item or items in the statement of income as other employee compensation costs arising from services rendered by the pertinent employees during the period. In addition, only the service cost component is eligible for capitalization. The other components of net benefit costs should be presented in the statement of income separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item is used to present the other components, that line item shall be described appropriately. The line items used in the income statement to present the components other than the service cost component shall be disclosed if a Company elects to not present them in a separate line item. The Company adopted ASU 2017-07 effective January 1, 2018. The amendments in ASU 2017-07 did not impact the Company's financial statements. In March 2017, the FASB issued ASU 2017-08, "Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. ASU 2017-08 does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company adopted ASU 2017-08 effective January 1, 2018. The amendments in ASU 2017-08 did not impact the Company's financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification." ASU 2017-09 was issued to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, to a change to the terms or conditions of a share-based payment award. Diversity in practice has arisen in part because some entities apply modification accounting under Topic 718 for modifications to terms and conditions that they consider substantive, but do not when they conclude that particular modifications are not substantive. Others apply modification accounting for any change to an award, except for changes that they consider purely administrative in nature. Still others apply modification accounting when a change to an award changes the fair value, the vesting, or the classification of the award. In practice, it appears that the evaluation of a change in fair value, vesting, or classification may be used to evaluate whether a change is substantive. ASU 2017-09 includes guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The Company adopted ASU 2017-09 effective January 1, 2018. The amendments in ASU 2017-09 did not impact the Company's financial statements as the Company has not historically had any scope modifications and has no plans to do so in the near future. In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." ASU 2018-02 was issued to address certain stranded tax effects in AOCI as a result of H.R.1., commonly referred to as the Tax Cuts and Jobs Act ("Tax Reform"). ASU 2018-02 provides companies the option to reclassify stranded tax effects within AOCI to retained earnings (or accumulated deficit) in each period in which the effect of the change from the newly enacted corporate tax rate is recorded. The amount of the reclassification is calculated on the basis of the difference between the historical and newly enacted tax rates for deferred tax assets and liabilities related to items within AOCI. ASU 2018-02 requires companies to disclose its accounting policy related to releasing income tax effects from accumulated other comprehensive income, whether it has elected to reclassify the stranded tax effects, and information about the other income tax effects that are reclassified. Although ASU 2018-02 was effective for the Company's reporting period beginning on January 1, 2019, the Company elected to early adopt the standard effective January 1, 2018. As a result, the Company recorded cumulative effect adjustments which increased opening retained earnings (or reduced opening accumulated deficit) and decreased AOCI for the stranded tax effects related to the Company's defined benefit pension and supplemental retirement plan obligations and the unrealized gain on the Company's investment securities portfolio by $1.4 million and $0.5 million , respectively.

REVENUE FROM CONTRACTS WITH C31

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers" , establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts to provide goods or services to its customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services. Revenue is recognized as performance obligations are satisfied. The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. Our principal source of revenue is derived from interest income on financial instruments, such as our loan and investment securities portfolios, as well as revenue related to our mortgage banking activities. These revenue-generating transactions are out of scope of ASC 606, but are subject to other GAAP and discussed elsewhere within our disclosures. We also generate other revenue in connection with our broad range of banking products and financial services. Descriptions of our other revenue-generating activities that are within the scope of ASC 606, which are presented in our consolidated statements of income as components of other operating income are as follows: Service charges on deposit accounts Revenue from service charges on deposit accounts includes general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as stop payment fees). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Other Service Charges and Fees Revenue from other service charges and fees includes cards and payments income, safe deposit rental income and other service charges, commissions and fees. Cards and payments income includes interchange fees from debit cards processed through card association networks, merchant services, and other card related services. Interchange rates are generally set by the credit card associations and based on purchase volumes and other factors. Interchange fees are recognized as transactions occur. Interchange expenses related to cards and payments income are presented gross in other operating expense. Merchant services income represents account management fees and transaction fees charged to merchants for the processing of card association network transactions. Merchant services revenue is recognized as transactions occur, or as services are performed. Other service charges, commissions and fees include automated teller machines ("ATM") surcharge and interchange fees, bill payment fees, cashier’s check and money order fees, wire transfer fees, loan brokerage fees, and commissions on sales of insurance, broker-dealer products, letters of credit, and travelers’ checks. Revenue from these fees and commissions is recorded in a manner that reflects the timing of when transactions occur, and as services are provided. Based on the nature of the commission agreement with the broker-dealer and each insurance provider, we may recognize revenue from broker-dealer and insurance commissions over time or at a point-in-time as our performance obligation is satisfied. Income from Fiduciary Activities Income from fiduciary activities includes fees from wealth management, trust, custodial and escrow services provided to individual and institutional customers. Revenue is generally recognized monthly based on a minimum annual fee and/or the market value of assets in custody. Additional fees are recognized for transactional activity. Revenue from trade execution and brokerage services is earned through commissions from trade execution on behalf of clients. Revenue from these transactions is recognized at the trade date. Any ongoing service fees are recognized on a monthly basis as services are performed. Loan Placement Fees Loan placement fees primarily represent revenues earned by the Company for loan placement and underwriting. Revenues for these services are recorded at a point-in-time, upon completion of a contractually identified transaction, or when an advisory opinion is provided.
