Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Central Pacific Financial Corp. is a bank holding company. Our principal operating subsidiary, Central Pacific Bank, is a full-service commercial bank with 35 branches and 78 ATMs located throughout the state of Hawaii. The bank engages in a broad range of lending activities including originating commercial loans, commercial and residential mortgage loans, home equity loans and consumer loans. The bank also offers a variety of deposit products and services. These include personal and business checking and savings accounts, money market accounts and time certificates of deposit. Other products and services include debit cards, internet banking, mobile banking, cash management services, safe deposit boxes, international banking services, night depository facilities, foreign exchange and wire transfers. Wealth management products and services include non-deposit investment products, annuities, insurance, investment management, asset custody and general consultation and planning services. When we refer to "the Company," "we," "us" or "our," we mean Central Pacific Financial Corp. and Subsidiaries (consolidated). When we refer to "Central Pacific Financial Corp." or to the holding company, we are referring to the parent company on a standalone basis. When we refer to "our bank" or "the bank," we mean "Central Pacific Bank." The banking business depends on rate differentials, the difference between the interest rates paid on deposits and other borrowings and the interest rates received on loans extended to customers and investment securities held in our portfolio. These rates are highly sensitive to many factors that are beyond our control. Accordingly, the earnings and growth of the Company are subject to the influence of domestic and foreign economic conditions, including inflation, recession and unemployment. We have the following three reportable segments: (1) Banking Operations, (2) Treasury and (3) All Others. The Banking Operations segment includes construction and commercial real estate lending, commercial lending, residential mortgage lending, consumer 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 and Treasury segments described above and includes activities such as electronic banking, data processing and management of bank owned properties. For further information, see Note 26 - Segment Information . Accounting Policy Change During the fourth quarter of 2018, we voluntarily changed our accounting policy for investments in low income housing tax credit ("LIHTC") partnerships from the cost method to the proportional amortization method using the practical expedient available under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 323, "Investments - Equity Method and Joint Ventures" , which permits an investor to amortize the initial cost of the investment in proportion to only the tax credits allocated to the investor. We believe the proportional amortization method is preferable because it better reflects the economics of an investment that is made for the primary purpose of receiving tax credits and other tax benefits. In addition to a change in the timing of the recognition of amortization expense on LIHTC investments, amortization expense on LIHTC investments is now reflected in the income tax expense line, which provides users a better understanding of the nature of the returns of such investments, instead of in other operating expenses on the consolidated statements of income. The change did not impact net income, the consolidated balance sheets and the consolidated statements of cash flows. As a result of this accounting policy change, the following presents the effect of the change on our consolidated statements of income for prior periods that were retrospectively adjusted: December 31, 2018 December 31, 2017 December 31, 2016 Consolidated statements Impact of Impact of Impact of of income: Unadjusted Adjusted Change Unadjusted Adjusted Change Unadjusted Adjusted Change (Dollars in thousands) Other operating expense $ 135,687 $ 134,682 $ (1,005 ) $ 131,817 $ 131,073 $ (744 ) $ 133,563 $ 132,518 $ (1,045 ) Income tax expense 17,753 18,758 1,005 33,852 34,596 744 25,228 26,273 1,045 Net income 59,486 59,486 — 41,204 41,204 — 46,992 46,992 — 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 met the consolidation requirements under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, " Consolidation ". The bank also concluded that the entity met the definition of a variable interest entity and that we were the primary beneficiary of the variable interest entity. Accordingly, the investment has been consolidated into our financial statements as of December 31, 2017 and 2016. One Hawaii HomeLoans, LLC was terminated in 2017, and final payment of taxes and distributions to members was made in March 2018. We have 50% ownership interests in four other mortgage loan origination and brokerage companies which are accounted for using the equity method and are included in investment in unconsolidated subsidiaries: Pacific Access Mortgage, LLC, Gentry HomeLoans, LLC, Haseko HomeLoans, LLC and Island Pacific HomeLoans, LLC. Pacific Access Mortgage, LLC was terminated in 2017, and final payment of taxes and distributions to members was made in March 2018. As previously discussed we have LIHTC investments that are now accounted for under the proportional amortization method and are included in investment in unconsolidated subsidiaries. We also have non-controlling equity investments in affiliates that are accounted for under the cost method and are also included in investment in unconsolidated subsidiaries. Our investments in unconsolidated subsidiaries accounted for under the equity, proportional amortization and cost methods were $0.2 million , $11.6 million and $2.2 million , respectively, at December 31, 2018 and $0.6 million , $3.6 million and $2.8 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. Use of Estimates The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions that reflect the reported amounts of assets and liabilities and disclosures of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance and provision for loan and lease losses, reserves for unfunded loan commitments, deferred income tax assets and income tax expense, valuation of investment securities, mortgage servicing rights and the related amortization thereon, pension liability and the fair value of certain financial instruments. Cash and Cash Equivalents Cash and cash equivalents include cash and due from financial institutions, interest-bearing deposits in other financial institutions, federal funds sold and all highly liquid investments with maturities of three months or less at the time of purchase. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and federal funds purchased and repurchase agreements. Investment Securities Investments in debt securities and mortgage-backed securities are designated as trading, available-for-sale, or held-to-maturity. Securities are designated as held-to-maturity only if we have the positive intent and ability to hold these securities to maturity. Held-to-maturity securities are reported at amortized cost. Trading securities are reported at fair value, with changes in fair value included in net income. Available-for-sale securities are reported at fair value, with net unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) ("AOCI"). Equity securities with readily determinable fair values are carried at fair value, with changes in fair value included in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Interest income on investment securities includes amortization of premiums and accretion of discounts. We amortize premiums to the earliest call date. We accrete discounts associated with investment securities using the interest method over the life of the respective security instrument. Management evaluates investment securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation, to determine whether the unrealized losses on investment securities, or the decline in their value below amortized cost is "other-than-temporary." The term other-than-temporary is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. In conducting this assessment, for debt securities in an unrealized loss position 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 decline in fair value subsequent to the balance sheet date. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the decline in value is determined to be other-than-temporary, the value of the security is reduced and a corresponding impairment charge to earnings is recognized for anticipated credit losses. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. The declines in market value were primarily attributable to changes in interest rates and volatility in the credit and financial markets. 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. We are a member of the Federal Home Loan Bank of Des Moines (the "FHLB"). The bank is required to obtain and hold a specific number of shares of capital stock of the FHLB equal to the sum of a membership investment requirement and an activity-based investment requirement. The securities are reported at cost and are presented separately in the consolidated balance sheets. Loans Held for Sale Loans held for sale consists of the following two types: (1) Hawaii residential mortgage loans that are originated with the intent to sell them in the secondary market and (2) non-residential mortgage loans in both Hawaii and the U.S. Mainland that were originated with the intent to be held in our portfolio but were subsequently transferred to the held for sale category. Hawaii residential mortgage loans classified as held for sale are carried at the lower of cost or fair value on an aggregate basis, while the non-residential Hawaii and U.S. Mainland loans are recorded at the lower of cost or fair value on an individual basis. Net fees and costs associated with originating and acquiring the Hawaii residential mortgage loans held for sale are deferred and included in the basis for determining the gain or loss on sales of loans held for sale. We report the fair values of the non-residential mortgage loans classified as held for sale net of applicable selling costs on our consolidated balance sheets. Loans originated with the intent to be held in our portfolio are subsequently transferred to held for sale when our intent to hold for the foreseeable future has changed. At the time of a loan's transfer to the held for sale account, the loan is recorded at the lower of cost or fair value. Any reduction in the loan's value is reflected as a write-down of the recorded investment resulting in a new cost basis, with a corresponding reduction in the allowance for loan and lease losses. In subsequent periods, if the fair value of a loan classified as held for sale is less than its cost basis, a valuation adjustment is recognized in our consolidated statement of income in other operating expense and the carrying value of the loan is adjusted accordingly. The valuation adjustment may be recovered in the event that the fair value increases, which is also recognized in our consolidated statement of income in other operating expense. 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. Collateral values are determined based on appraisals received from qualified valuation professionals and are obtained periodically or when indicators that property values may be impaired are present. We sell residential mortgage loans under industry standard contractual provisions that include various representations and warranties, which typically cover ownership of the loan, compliance with loan criteria set forth in the applicable agreement, validity of the lien securing the loan, and other similar matters. We may be required to repurchase certain loans sold with identified defects, indemnify the investor, or reimburse the investor for any credit losses incurred. Our repurchase risk generally relates to early payment defaults and borrower fraud. We establish residential mortgage repurchase reserves to reflect this risk based on our estimate of losses after considering a combination of factors, including our estimate of future repurchase activity and our projection of incurred credit losses resulting from repurchased loans. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the principal amount outstanding, net of deferred loan fees (costs). Net deferred loan fees (costs) are recognized over the life of the related loan as an adjustment to yield and are amortized using the interest method over the contractual term of the loan, adjusted for actual prepayments. Unamortized fees (costs) on loans paid in full are recognized as a component of interest income. Interest income on loans is recognized on an accrual basis. 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. Loans are placed on nonaccrual status when interest payments are 90 days past due, or earlier should management determine that the borrowers will be unable to meet contractual principal and/or interest obligations, unless the loans are well-secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income should management determine that the collectibility of such accrued interest is doubtful. All subsequent receipts are applied to principal outstanding and no interest income is recognized unless the financial condition and payment record of the borrowers warrant such recognition. A nonaccrual loan may be restored to an accrual basis when principal and interest payments are current and full payment of principal and interest is expected. Allowance for Loan and Lease Losses The allowance for loan and lease losses (the "Allowance") is a valuation allowance established through provisions for loan and lease losses (the "Provision") charged against income. Our policy is to charge a loan off in the period in which the loan is deemed to be uncollectible and all interest previously accrued but not collected is reversed against current period interest income. We consider a loan to be uncollectible when it is probable that a loss has been incurred and the Company can make a reasonable estimate of the loss. In these instances, the likelihood of and/or timeframe for recovery of the amount due is uncertain, weak, or protracted. Subsequent receipts, if any, are credited first to the remaining principal, then to the Allowance as recoveries, and finally to unaccrued interest. The Allowance is management's estimate of incurred credit losses inherent in our loan and lease portfolio at the balance sheet date. In determining the amount of our Allowance, we rely on an analysis of our loan portfolio, our experience and our evaluation of general economic conditions, as well as regulatory requirements. We maintain our Allowance at an amount we expect to be sufficient to absorb probable losses inherent in our loan and lease portfolio based on a projection of probable net loan charge-offs. The Company's approach to developing the Allowance has three basic elements. These elements include specific reserves for individually impaired loans, a general allowance for loans other than those analyzed as individually impaired, and qualitative adjustments based on environmental and other factors which may be internal or external to the Company. These three elements are explained below. Specific Reserve Individually impaired loans in all loan categories are evaluated using one of three valuation methods as prescribed under Accounting Standards Codification ("ASC") 310-10, Fair Value of Collateral, Observable Market Price, or Cash Flow . A loan is generally evaluated for impairment on an individual basis if it meets one or more of the following characteristics: risk-rated as substandard, doubtful or loss, loans on nonaccrual status, troubled debt restructures, or any loan deemed prudent by management to so analyze. If the valuation of the impaired loan is less than the recorded investment in the loan, the deficiency will be charged off against the Allowance or, alternatively, a specific reserve will be established and included in the overall Allowance balance. General Allowance In determining the general allowance component of the Allowance, the Company utilizes a comprehensive approach to segment the loan portfolio into homogeneous groups. The Company's methodology segments the portfolio generally by FDIC Call Report codes in eleven segments, and is consistent with general industry practice. For the purpose of determining general allowance loss factors, loss experience is derived from a migration analysis, with the exception of national syndicated loans and auto dealer purchased loans where an average historical loss rate is applied due to limited historical loss experience. The key inputs to run a migration analysis are the length of the migration period, the dates for the migration periods to start and the number of migration periods used for the analysis. For each migration period, the analysis will determine the outstanding balance in each segment and/or sub-segment at the start of each period. These loans will then be followed for the length of the migration period to identify the amount of associated charge-offs and recoveries. A loss rate for each migration period is calculated using the formula ‘net charge-offs over the period divided by beginning loan balance'. The Allowance methodology applies a look back period to January 1, 2010. The Company extends its look back period with each additional quarter passing. As of December 31, 2018 , the look back period was nine years. Qualitative Adjustments Our Allowance methodology uses qualitative adjustments to address changes in conditions, trends, and circumstances such as economic conditions and industry changes that could have a significant impact on the risk profile of the loan portfolio, and provide for losses in the loan portfolio that may not be reflected and/or captured in the historical loss data. In order to ensure that the qualitative adjustments are in compliance with current regulatory standards and U.S. GAAP, the Company is primarily basing adjustments on the nine standard factors outlined in the 2006 Interagency Policy Statement on the Allowance for Loan and Lease Losses. These factors include: lending policies, economic conditions, loan profile, lending staff, problem loan trends, loan review, collateral, credit concentrations and other internal and external factors. In recognizing that current and relevant environmental (economic, market or other) conditions that can affect repayment may not yet be fully reflected in historical loss experience, qualitative adjustments are applied to factor in current loan portfolio and market intelligence. These adjustments, which are added to the historical loss rate, consider the nature of the Company's primary markets and are reasonable, consistently determined and appropriately documented. Management reviews the results of the qualitative adjustment quarterly to ensure it is consistent with the trends in the overall economy, and from time to time may make adjustments, if necessary, to ensure directional consistency. Reserve for Unfunded Commitments Our process for determining the reserve for unfunded loan commitments utilizes historical loss rates and is adjusted for estimated loan funding probabilities. The reserve for unfunded loan commitments is recorded separately through a valuation allowance included in other liabilities. Credit losses for off-balance sheet credit exposures are deducted from the allowance for credit losses on off-balance sheet credit exposures in the period in which the liability is settled. The allowance for credit losses on off-balance sheet credit losses is established by a charge to other operating expense. Premises and Equipment Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are included in other operating expense and are computed using the straight-line method over the shorter of the estimated useful lives of the assets or the applicable leases. Useful lives generally range from five to thirty-nine years for premises and improvements, and one to seven years for equipment. Major improvements and betterments are capitalized, while recurring maintenance and repairs are charged to operating expense. Net gains or losses on dispositions of premises and equipment are included in other operating income and operating expense. Core Deposit Premium and Mortgage Servicing Rights Our core deposit premium was amortized over 14 years which approximated the estimated life of the purchased deposits. 2018 was the final year of amortization. The carrying value of our core deposit premium was periodically evaluated to estimate the remaining periods of benefit. If these periods of benefit were determined to be less than the remaining amortizable life, an adjustment to reflect such shorter life would have been made. Mortgage servicing rights are recorded when loans are sold to third-parties with servicing of those loans retained and we classify and pool our mortgage servicing rights into buckets of homogeneous characteristics. We utilize the amortization method to measure our mortgage servicing rights. Under the amortization method, we amortize our mortgage servicing rights in proportion to and over the period of net servicing income. Income generated as the result of new mortgage servicing rights is reported as gains on sales of loans and is a component of mortgage banking income in the other operating income section of our consolidated statements of income. Amortization of the servicing rights is also reported as a component of mortgage banking income. Ancillary income is recorded in other income. 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 and 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, servicing cost and ancillary income. 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. Prepayment speeds may be affected by economic factors such as home price appreciation, market interest rates, the availability of other credit products to our borrowers and customer payment patterns. Prepayment speeds include the impact of all borrower prepayments, including full payoffs, additional principal payments and the impact of loans paid off due to foreclosure liquidations. We perform an impairment assessment of our mortgage servicing rights quarterly or whenever events or changes in circumstance indicate that the carrying value of those assets may not be recoverable. Our impairment assessments involve, among other valuation methods, the estimation of future cash flows and other methods of determining fair value. Estimating future cash flows and determining fair values is subject to judgments and often involves the use of significant estimates and assumptions. The variability of the factors we use to perform our impairment tests depend on a number of conditions, including the uncertainty about future events and cash flows. All such factors are interdependent and, therefore, do not change in isolation. Accordingly, our accounting estimates may materially change from period to period due to changing market factors. Other Real Estate Other real estate is composed of properties acquired through foreclosure proceedings and is initially recorded at fair value less estimated costs to sell the property, thereby establishing the new cost basis of other real estate. Losses arising at the time of acquisition of such properties are charged against the Allowance. Subsequent to acquisition, such properties are carried at the lower of cost or fair value less estimated selling expenses, determined on an individual asset basis. Any deficiency resulting from the excess of cost over fair value less estimated selling expenses is recognized as a valuation allowance. Any subsequent increase in fair value up to its cost basis is recorded as a reduction of the valuation allowance. Increases or decreases in the valuation allowance are included in other operating expense. Net gains or losses recognized on the sale of these properties are included in other operating income. Non-Controlling Interest Non-controlling interest was comprised of capital and undistributed profits of the member of One Hawaii HomeLoans, LLC, other than the bank. Non-controlling interest on our consolidated balance sheet at December 31, 2018 and December 31, 2017 totaled $0 and $24 thousand , respectively. One Hawaii HomeLoans, LLC was terminated in 2017, and final payment of taxes and distributions to members was made in March 2018 . Share-Based Compensation Share-based compensation cost is measured at the grant date, based on the estimated fair value of the award. We use the Black-Scholes option-pricing model to determine the fair-value of stock options, and the market price of the Company's common stock at the grant date for restricted stock awards. Share-based compensation is recognized as expense over the employee's requisite service period, generally defined as the vesting period. For awards with graded vesting, we recognize compensation expense on a straight-line basis over their respective vesting period. The Company's accounting policy is to recognize forfeitures as they occur. See Note 16 - Share-Based Compensation for further discussion of our stock-based compensation. Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax effects attributable to temporary differences and carryforwards. A valuation allowance may be required if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. In determining whether a valuation allowance is necessary, we consider the level of taxable income in prior years, to the extent that carrybacks are permitted under current tax laws, as well as estimates of future taxable income and tax planning strategies that could be implemented to accelerate taxable income, if necessary. If our estimates of future taxable income were materially overstated or if our assumptions regarding the tax consequences of tax planning strategies were inaccurate, some or all of our deferred tax assets may not be realized, which would result in a charge to earnings. We recognize interest and penalties related to income tax matters in other expense. We establish income tax contingency reserves for potential tax liabilities related to uncertain tax positions. Tax benefits are recognized when we determine that it is more likely than not that such benefits will be realized. Where uncertainty exists due to the complexity of income tax statutes, and where the potential tax amounts are significant, we generally seek independent tax opinions to support our positions. If our evaluation of the likelihood of the realization of benefits is inaccurate, we could incur additional income tax and interest expense that would adversely impact earnings, or we could receive tax benefits greater than anticipated which would positively impact earnings.

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 AOCI by $0.1 million related to the unrealized gains on the equity investment securities portfolio. Changes in the fair value of the equity investment securities portfolio are now recognized in net income. The amortized cost and estimated fair value of our investment securities at December 31, 2018 by contractual maturity are shown below. Actual maturities may differ from contractual maturities as issuers have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

In the second quarter of 2017, we completed an investment portfolio repositioning strategy designed to enhance potential prospective earnings and improve net interest margin. In connection with the repositioning, we sold $97.7 million in lower-yielding available-for-sale securities, and purchased $97.4 million in higher-yielding, longer duration investment securities. The investment securities sold had an average yield of 1.91% . Gross proceeds of the sale of $96.0 million were immediately reinvested back into investment securities with an average yield of 2.57% . The new securities were classified in the available-for-sale portfolio. There were no gross realized gains on the sale of the investment securities. Gross realized losses on the sale of the investment securities were $1.6 million . The specific identification method was used as the basis for determining the cost of all securities sold. There were no investment security sales in 2016 . Investment securities of $0.98 billion and $1.08 billion at December 31, 2018 and 2017 , respectively, were pledged to secure public funds on deposit and other long-term and short-term borrowings. At December 31, 2018 and 2017 , there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders' equity. There were a total of 336 and 223 securities in an unrealized or unrecognized loss position at December 31, 2018 and 2017 , respectively. The following table summarizes securities which were in an unrealized or unrecognized loss position at December 31, 2018 and 2017 , aggregated by major security type and length of time in a continuous unrealized or unrecognized loss position: Less Than 12 Months 12 Months or Longer Total Description of Securities Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) December 31, 2018 Debt securities: States and political subdivisions $ 38,099 $ (157 ) $ 49,505 $ (1,318 ) $ 87,604 $ (1,475 ) Corporate securities 49,729 (250 ) 5,120 (160 ) 54,849 (410 ) U.S. Treasury obligations and direct obligations of U.S Government agencies 30,029 (613 ) 2,545 (70 ) 32,574 (683 ) Mortgage-backed securities: Residential - U.S. Government-sponsored entities ("GSEs") 88,957 (1,229 ) 666,685 (21,437 ) 755,642 (22,666 ) Residential - Non-government sponsored entities ("Non-GSEs"). — — 24,515 (464 ) 24,515 (464 ) Commercial - U.S. GSEs and agencies 13,973 (247 ) 101,500 (2,365 ) 115,473 (2,612 ) Commercial - Non-GSEs 33,847 (233 ) 46,680 (919 ) 80,527 (1,152 ) Total temporarily impaired securities $ 254,634 $ (2,729 ) $ 896,550 $ (26,733 ) $ 1,151,184 $ (29,462 ) Less Than 12 Months 12 Months or Longer Total Description of Securities Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) December 31, 2017 Debt securities: States and political subdivisions $ 53,811 $ (305 ) $ 15,403 $ (414 ) $ 69,214 $ (719 ) Corporate securities — — 5,307 (76 ) 5,307 (76 ) U.S. Treasury obligations and direct obligations of U.S Government agencies 10,740 (69 ) — — 10,740 (69 ) Mortgage-backed securities: Residential - U.S. Government-sponsored entities ("GSEs") 335,883 (3,372 ) 340,219 (8,639 ) 676,102 (12,011 ) Commercial - U.S. GSEs and agencies 130,763 (723 ) — — 130,763 (723 ) Commercial - Non-GSEs 28,490 (193 ) — — 28,490 (193 ) Total temporarily impaired securities $ 559,687 $ (4,662 ) $ 360,929 $ (9,129 ) $ 920,616 $ (13,791 ) The unrealized losses on the Company's investment securities are primarily attributable to changes in interest rates and volatility in the credit and financial markets. Investment securities are evaluated on at least a quarterly basis, and include evaluating the changes in the investment securities' ratings issued by rating agencies and changes in the financial condition of the issuer, and for mortgage related securities, delinquency and loss information with respect to the underlying collateral, changes in levels of subordination for the Company's particular position within the repayment structure, and remaining credit enhancement as compared to projected credit losses of the security. All of these investment securities continue to be investment grade rated by one or more major rating agencies. 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. Visa and MasterCard Class B Common Stock As of December 31, 2018 , the Company owned 34,631 shares and 11,170 shares of Class B common stock of Visa, Inc. ("Visa") and MasterCard, Inc. ("MasterCard"), respectively. Due to transfer restrictions and the lack of readily determinable fair values of Class B common stock of Visa and MasterCard, the Company chooses to carry the shares on the Company's consolidated balance sheets at zero cost basis.

The construction and real estate segment's predominant risk characteristics are the collateral and the geographic location of the property collateralizing the loan, as well as the operating cash flow for the commercial real estate properties. The commercial, financial and agricultural (and leases) segment's predominant risk characteristics are the cash flows of the business we lend to, the global cash flows and liquidity of the guarantors of such losses, as well as economic and market conditions. The consumer segment's predominant risk characteristics are employment and income levels as they relate to the consumer. During the year ended December 31, 2018 , we foreclosed on one portfolio loan with a carrying value of $40 thousand , which was sold at a small premium to book value. We did not transfer any loans to the held-for-sale category during the year ended December 31, 2018 . In addition, we did not sell any other portfolio loans during the year ended December 31, 2018 .

For the years ended December 31, 2018 , 2017 and 2016 , the amount of interest income recognized using a cash-based method of accounting during the period that the loans were impaired was not material. Foreclosure Proceedings The Company had $0.7 million and $40 thousand of residential mortgage loans collateralized by residential real estate property that were in the process of foreclosure at December 31, 2018 and 2017 , respectively. 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 December 31, 2018 and 2017 : Accruing Accruing Accruing Loans Greater Than 90 Days Past Due Nonaccrual Total Loans and Total (Dollars in thousands) December 31, 2018 Commercial, financial and agricultural $ 1,348 $ 162 $ — $ — $ 1,510 $ 580,150 $ 581,660 Real estate: Construction — — — — — 66,927 66,927 Residential mortgage 3,966 157 — 2,048 6,171 1,422,034 1,428,205 Home equity 433 104 298 275 1,110 467,856 468,966 Commercial mortgage — — — — — 1,040,278 1,040,278 Consumer 2,340 872 238 — 3,450 488,756 492,206 Leases — — — — — 124 124 Total $ 8,087 $ 1,295 $ 536 $ 2,323 $ 12,241 $ 4,066,125 $ 4,078,366 Accruing Accruing Accruing Loans Greater Than 90 Days Past Due Nonaccrual Total Loans and Total (Dollars in thousands) December 31, 2017 Commercial, financial and 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 Interest income totaling $1.2 million , $2.6 million , and $0.6 million was recognized on nonaccrual loans, including loans held for sale, in 2018 , 2017 and 2016 , respectively. Additional interest income of $0.4 million , $0.4 million , and $1.2 million would have been recognized in 2018 , 2017 and 2016 , respectively, had these loans been accruing interest throughout those periods. Additionally, interest income of $0.7 million , $0.8 million , and $1.3 million was collected and recognized on charged-off loans in 2018 , 2017 and 2016 , respectively. Modifications TDRs included in nonperforming assets at December 31, 2018 consisted of three Hawaii residential mortgage loans with a combined principal balance of $0.4 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. At December 31, 2017 , TDRs included in nonperforming assets consisted of six loans with a combined principal balance of $0.6 million . There were $12.9 million of TDRs still accruing interest at December 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 methodology. As a result, some loans 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 and Allowance during the years ended December 31, 2018 and 2017 . The following table presents by class, information related to loans modified in a TDR during the years ended December 31, 2018 , 2017 and 2016 : Year Ended December 31, 2018 Number Recorded Increase (Dollars in thousands) Real estate: Residential mortgage 3 $ 575 $ — Total 3 $ 575 $ — Year Ended December 31, 2017 Number Recorded Increase (Dollars in thousands) Real estate: Residential mortgage 3 $ 104 $ — Total 3 $ 104 $ — Year Ended December 31, 2016 Number Recorded Increase (Dollars in thousands) Real estate: Residential mortgage 3 $ 282 $ — Total 3 $ 282 $ — No loans were modified as a TDR within the previous twelve months that subsequently defaulted during the years ended December 31, 2018 , 2017 and 2016 . 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 as to 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 estimate 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 loans and leases.

In determining the amount of our Allowance, we rely on an analysis of our loan portfolio, our experience and our evaluation of general economic conditions, as well as regulatory requirements and input. If our assumptions prove to be incorrect, our current Allowance may not be sufficient to cover future loan losses and we may experience significant increases to our Provision.

As of December 31, 2018 and 2017 , the Company had $8.3 million and $2.6 million , respectively, in unfunded commitments related to the LIHTC partnerships. The expected payments for the unfunded commitments as of December 31, 2018 are as follows (in thousands): Year Ending December 31: 2019 $ 4,634 2020 3,466 2021 94 2022 10 2023 10 Thereafter 70 Total commitments $ 8,284 Prior to 2018, the Company's investments in LIHTC partnerships were accounted for using the cost method. In 2018, the Company voluntarily changed its accounting policy for LIHTC partnerships from the cost method to the proportional amortization method using the practical expedient available under ASC 323, "Investments - Equity Method and Joint Ventures" , which permits an investor to amortize the initial cost of the investment in proportion to only the tax credits allocated to the investor. The Company believes the proportional amortization method is preferable because it better reflects the economics of an investment that is made for the primary purpose of receiving tax credits and other tax benefits. In addition to a change in the timing of the recognition of amortization expense on LIHTC investments, amortization expense on LIHTC investments is now reflected in the income tax expense line, which provides users a better understanding of the nature of the returns of such investments, instead of in other operating expenses on the consolidated statements of income. Prior period results were adjusted to reflect this change in accounting policy. See Note 1 - Summary of Significant Accounting Policies to our consolidated financial statements for further discussion of the change in accounting policy applied to these investments. The following table presents amortization expense and tax credits recognized associated with our investments in LIHTC partnerships for the periods presented: Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Proportional amortization method: Amortization expense recognized in income tax expense $ 1,005 $ 744 $ 1,045 Federal and state tax credits recognized in income tax expense 759 919 1,174

Based on our mortgage servicing rights held as of December 31, 2018 , estimated amortization expense for the next five succeeding fiscal years and all years thereafter are as follows (dollars in thousands): Year Ending December 31: 2019 $ 1,615 2020 1,315 2021 1,100 2022 931 2023 781 Thereafter 9,854 Total $ 15,596 We utilize the amortization method to measure our mortgage servicing rights. Under the amortization method, we amortize our mortgage servicing rights in proportion to and over the period of net servicing income. Income generated as the result of new mortgage servicing rights is reported as a component of mortgage banking income and totaled $1.6 million , $2.4 million , and $3.0 million in 2018 , 2017 and 2016 , respectively. Amortization of the servicing rights is reported as a component of mortgage banking income in our consolidated statements of income. Ancillary income is recorded in other income. Mortgage servicing rights are recorded when loans are sold to third-parties with servicing of those loans retained and we classify and pool our mortgage servicing rights into buckets of homogeneous characteristics. 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 and 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, servicing costs and ancillary income. 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. Prepayment speeds may be affected by economic factors such as home price appreciation, market interest rates, the availability of other credit products to our borrowers and customer payment patterns. Prepayment speeds include the impact of all borrower prepayments, including full payoffs, additional principal payments and the impact of loans paid off due to foreclosure liquidations. As market interest rates decline, prepayment speeds will generally increase as customers refinance existing mortgages under more favorable interest rate terms. As prepayment speeds increase, anticipated cash flows will generally decline resulting in a potential reduction, or impairment, to the fair value of the capitalized mortgage servicing rights. Alternatively, an increase in market interest rates may cause a decrease in prepayment speeds and therefore an increase in fair value of mortgage servicing rights. The following table presents the fair market value and key assumptions used in determining the fair market value of our mortgage servicing rights: Year Ended December 31, 2018 2017 (Dollars in thousands) Fair market value, beginning of period $ 17,161 $ 18,087 Fair market value, end of period 17,696 17,161 Weighted average discount rate 9.5 % 9.5 % Weighted average prepayment speed assumption 14.5 % 16.0 % Loans serviced for others as of December 31, 2018 and 2017 totaled $2.01 billion and $2.08 billion , respectively. Loans serviced for others are not reported as assets on the Company's consolidated balance sheets.

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. At 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 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. We had no derivative instruments designated as hedging instruments as of December 31, 2018 and December 31, 2017 . 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 lock 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 December 31, 2018 , we were a party to interest rate lock and forward sale commitments on $2.2 million and $8.5 million of mortgage loans, respectively. At December 31, 2017 , we were a party to interest rate lock and forward sale commitments on $2.5 million and $18.7 million of mortgage loans, respectively.

Interest expense on FHLB long-term advances was $0.2 million in 2018 . There was no interest expense on long-term FHLB advances in 2017 and 2016 . Subordinated Debentures In October 2003, we created two wholly-owned statutory trusts, CPB Capital Trust II, a Delaware statutory trust ("Trust II") and CPB Statutory Trust III, a Delaware statutory trust ("Trust III"). Trust II issued $20.0 million in floating rate trust preferred securities bearing an interest rate of three-month London Interbank Offered Rate ("LIBOR") plus 2.85% and maturing on October 7, 2033. The principal assets of Trust II are $20.6 million of the Company's junior subordinated debentures with an identical interest rate and maturity as the Trust II trust preferred securities. Trust II issued $0.6 million of common securities to the Company. On November 13, 2018, the Company submitted a notice to the trustee and security holder to redeem, in whole and at par, the $20.0 million of trust preferred securities issued by Trust II. The trust preferred securities were redeemed, along with the $0.6 million in common securities issued by Trust II and held by the Company, as a result of the concurrent redemption of 100% of the Company's outstanding floating rate junior subordinated debentures held by Trust II, which underlay the trust preferred securities. The redemption was pursuant to the optional prepayment provisions of the indenture and occurred on January 7, 2019. The redemption price for the floating rate junior subordinated debentures was equal to 100% of the principal amount plus accrued interest, up to, but not including, the redemption date. The proceeds from the redemption of the floating rate junior subordinated debentures was simultaneously applied to redeem all of the outstanding floating rate trust preferred securities at a price of 100% of the aggregate liquidation amount of the securities plus accumulated but unpaid distributions up to but not including the redemption date. The Company received all necessary regulatory approvals for the redemption. The redemption was funded with excess cash currently available to the Company. On December 17, 2018, the Company completed the redemption of $20.0 million in floating rate trust preferred securities of Trust III bearing an interest rate of three-month LIBOR plus 2.85% and maturing on December 17, 2033. The redemption price was price was 100% of the aggregate liquidation amount of the securities plus accumulated but unpaid distributions up to but not including the redemption date. The Company also redeemed $0.6 million of common securities issued by Trust III and held by the Company, as a result of the concurrent redemption of 100% of the principal assets of Trust III, or $20.6 million of the Company's junior subordinated debentures with an identical interest rate and maturity as the Trust III trust preferred securities. The redemption was pursuant to the optional prepayment provisions of the indenture. In September 2004, we created a wholly-owned statutory trust, CPB Capital Trust IV ("Trust IV"). Trust IV issued $30.0 million in floating rate trust preferred securities bearing an interest rate of three-month LIBOR plus 2.45% and maturing on December 15, 2034. The principal assets of Trust IV are $30.9 million of the Company's junior subordinated debentures with an identical interest rate and maturity as the Trust IV trust preferred securities. Trust IV issued $0.9 million of common securities to the Company. In December 2004, we created a wholly-owned statutory trust, CPB Statutory Trust V ("Trust V"). Trust V issued $20.0 million in floating rate trust preferred securities bearing an interest rate of three-month LIBOR plus 1.87% and maturing on December 15, 2034. The principal assets of Trust V are $20.6 million of the Company's junior subordinated debentures with an identical interest rate and maturity as the Trust V trust preferred securities. Trust V issued $0.6 million of common securities to the Company. The Company is not considered the primary beneficiary of Trusts II, III, IV and V, therefore the trusts are not considered a variable interest entity and are not consolidated in the Company's financial statements. Rather the subordinated debentures are shown as a liability on the Company's consolidated balance sheets. The Company's investment in the common securities of the trusts are included in investment in unconsolidated subsidiaries in the Company's consolidated balance sheets. The floating rate trust preferred securities, the junior subordinated debentures that are the assets of Trusts IV and V and the common securities issued by Trusts IV and V are redeemable in whole or in part on any interest payment date on or after December 15, 2009 for Trust IV and V, or at any time in whole but not in part within 90 days following the occurrence of certain events. Our obligations with respect to the issuance of the trust preferred securities constitute a full and unconditional guarantee by the Company of each trust's obligations with respect to its trust preferred securities. Subject to certain exceptions and limitations, we may elect from time to time to defer interest payments on the subordinated debentures, which would result in a deferral of distribution payments on the related trust preferred securities, for up to 20 consecutive quarterly periods without default or penalty. The subordinated debentures may be included in Tier 1 capital, with certain limitations applicable, under current regulatory guidelines and interpretations. At December 31, 2018 , future principal payments on long-term debt based on redemption date or final maturity are as follows (in thousands): Year Ending December 31: 2019 $ 20,619 2020 25,000 2021 25,000 2022 — 2023 — Thereafter 51,547 Total $ 122,166

Equity [Abstract]
EQUITY	13. 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 December 31, 2018 , the bank had Statutory Retained Earnings of $46.6 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. We repurchase shares of our common stock when we believe such repurchases are in the best interests of the Company. On May 20, 2014, our Board of Directors authorized the repurchase and retirement of up to $30.0 million of the Company's outstanding common stock (the "2014 Repurchase Plan"). In January 2015, our Board of Directors increased the authorization under the 2014 Repurchase Plan by $25.0 million .

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	14. 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. Fees on Foreign Exchange The Company provides foreign currency exchange services to customers, whereby cash can be converted to different foreign currencies, and vice versa. As a result of the services, a gain or loss is recognized on foreign currency transactions, as well as income related to commissions and fees earned on each transaction. Revenue from the commissions and fees earned on the transactions fall within the scope of ASC 606, and is recorded in a manner that reflects the timing of when transactions occur, and as services are provided. Realized and unrealized gains or losses related to foreign currency are out of scope of ASC 606. 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. Gain on Sales of Foreclosed Assets The Company records a gain or loss on the sale of a foreclosed property when control of the property transfers to the Company, which typically occurs at the time the deed is executed. The Company does not finance the sale of the foreclosed property. 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 period presented: Year Ended December 31, (dollars in thousands) 2018 Other operating income: In-scope of ASC 606 Service charges on deposit accounts $ 8,406 Other service charges and fees 11,078 Income on fiduciary activities 4,245 Net gain on sales of foreclosed assets — Fees on foreign exchange 110 Loan placement fees 747 In-scope other operating income 24,586 Out-of-scope other operating income 14,218 Total other operating income $ 38,804

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION	16. SHARE-BASED COMPENSATION In accordance with ASC 718, compensation expense is recognized only for those shares expected to vest, based on the Company's historical experience and future expectations. The following table summarizes the effects of share-based compensation for options and awards granted under the Company's equity incentive plans for each of the periods presented: Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Salaries and employee benefits $ 3,787 $ 3,266 $ 3,094 Directors stock awards 255 150 97 Income tax benefit (1,227 ) (1,903 ) (1,269 ) Net share-based compensation effect $ 2,815 $ 1,513 $ 1,922 Upon exercise or vesting of a share-based award, if the tax deduction exceeds the compensation cost that was previously recorded for financial statement purposes, this will result in an excess tax benefit. Effective January 1, 2017, ASU 2016-09, " Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting " requires the Company to recognize all excess tax benefits or tax deficiencies through the income statement as income tax expense/benefit. Under previous GAAP, any excess tax benefits were recognized in additional-paid-in-capital to offset current-period and subsequent-period tax deficiencies. During 2018 and 2017 , the Company recorded an income tax benefit of $0.1 million and $0.5 million , respectively, as a result of restricted stock units vesting during the year. The Company's share-based compensation arrangements are described below: Equity Incentive Plans We have adopted equity incentive plans for the purpose of granting options, restricted stock and other equity based awards for the Company's common stock to directors, officers and other key individuals. Option awards are generally granted with an exercise price equal to the market price of the Company's common stock at the date of grant; those option awards generally vest based on three or five years of continuous service and have 10 -year contractual terms. Certain option and share awards provide for accelerated vesting if there is a change in control (as defined in the stock option plans below). We have historically issued new shares of common stock upon exercises of stock options and purchases of restricted awards. In September 2004, we adopted and our shareholders approved the 2004 Stock Compensation Plan ("2004 Plan") making available 1,500,000 shares for grants to employees and directors. Upon adoption of the 2004 Plan, all unissued shares from the previous 1997 Plan were frozen and no new options were granted under the 1997 Plan. In May 2007, the 2004 Plan was amended to increase the number of shares available for grant by an additional 1,000,000 shares. In April 2011, the 2004 Plan was amended to increase the number of shares authorized from 1,402,589 to 4,944,831 . In April 2013, we adopted and our shareholders approved the 2013 Stock Compensation Plan ("2013 Plan") making available 2,200,000 shares for grants to employees and directors. Upon adoption of the 2013 Plan, all unissued shares from the 2004 Plan were frozen and no new grants will be granted under the 2004 Plan. Shares may continue to be settled under the 2004 Plan pursuant to previously outstanding awards. New shares are issued from the 2013 Plan. As of December 31, 2018 , 2017 and 2016 , a total of 1,468,137 , 1,567,912 and 1,671,752 shares, respectively, were available for future grants under our 2013 Plan. Stock Options The fair value of each option award is estimated on the date of grant based on the following: Valuation and amortization method— We estimate the fair value of stock options granted using the Black-Scholes option pricing formula and a single option award approach. We use historical data to estimate option exercise and employee termination activity within the valuation model; separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Expected life— The expected life of options represents the period of time that options granted are expected to be outstanding. Expected volatility— Expected volatilities are based on the historical volatility of the Company's common stock. Risk-free interest rate— The risk-free interest rate for periods within the contractual life of the option is based on the Treasury yield curve in effect at the time of grant. Expected dividend— The expected dividend assumption is based on our current expectations about our anticipated dividend policy. The following is a summary of option activity for our stock option plans for the year ended December 31, 2018 : Number Weighted Weighted Aggregate Stock options outstanding as of January 1, 2018 160,259 $ 19.22 Changes during the year: Granted — — Exercised (10,940 ) 14.31 Expired (1,549 ) 377.60 Forfeited (126 ) 79.00 Stock options outstanding as of December 31, 2018 147,644 $ 15.77 3.3 $ 1,449 Vested and exercisable as of December 31, 2018 147,644 $ 15.77 3.3 $ 1,449 The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying option awards and the quoted price of the Company's common stock for the options that were in-the-money as of December 31, 2018 . During the years ended December 31, 2018 and 2016 , the aggregate intrinsic value of options exercised under our stock option plan determined as of the date of exercise was $0.2 million and $0.8 million , respectively. There were no options exercised during the year ended December 31, 2017 . As of December 31, 2018 , all compensation costs related to stock options granted to employees under our stock option plans have been recognized. As of December 31, 2018 , all shares have been vested. There were no shares that vested in 2018 . The total fair value of options vested during the years ended December 31, 2017 and 2016 was $0.5 million , and $0.4 million , respectively. No stock options were granted during the years ended December 31, 2018 , 2017 and 2016 . Restricted Stock Awards and Units Under the 1997, 2004 and 2013 Plans, we awarded restricted stock awards and units to our non-officer directors and certain senior management personnel. The awards typically vest over a three or five year period from the date of grant and are subject to forfeiture until performance and employment targets are achieved. Compensation expense is measured as the market price of the stock awards on the grant date, and is recognized over the specified vesting periods. As of December 31, 2018 , there was $6.1 million of total unrecognized compensation cost related to restricted stock awards and units that is expected to be recognized over a weighted-average period of 2.3 years . The table below presents the activity of restricted stock awards and units for each of the periods presented: Number Weighted Fair Value Unvested as of December 31, 2015 463,917 $ 17.41 Changes during the year: Granted 296,078 23.65 Forfeited (66,972 ) 20.97 Vested (255,326 ) 15.83 $ 5,806 Unvested as of December 31, 2016 437,697 22.01 Changes during the year: Granted 126,204 31.35 Forfeited (31,570 ) 24.89 Vested (134,780 ) 19.81 4,224 Unvested as of December 31, 2017 397,551 25.49 Changes during the year: Granted 118,846 29.47 Forfeited (25,481 ) 27.39 Vested (128,191 ) 24.59 3,763 Unvested as of December 31, 2018 362,725 26.98

Retirement Benefits [Abstract]
PENSION PLANS	17. PENSION PLANS Defined Benefit Retirement Plan The bank has a defined benefit retirement plan that covered substantially all of its employees who were employed during the period that the plan was in effect. The plan was initially curtailed in 1986, and accordingly, plan benefits were fixed as of that date. Effective January 1, 1991, the bank reactivated its defined benefit retirement plan. As a result of the reactivation, employees for whom benefits were fixed in 1986 began to accrue additional benefits under a new formula that became effective January 1, 1991. Employees who were not participants at curtailment, but who were subsequently eligible to join, became participants effective January 1, 1991. Under the reactivated plan, benefits are based upon the employees' years of service and their highest average annual salaries in a 60 -consecutive-month period of service, reduced by benefits provided from the bank's terminated money purchase pension plan. The reactivation of the defined benefit retirement plan resulted in an increase of $5.9 million in the unrecognized prior service cost, which was amortized over a period of 13 years. Effective December 31, 2002, the bank curtailed its defined benefit retirement plan, and accordingly, plan benefits were fixed as of that date. In December 2016, the Company purchased non-participating annuity contracts totaling $9.4 million to settle the pension obligation for a portion of the Company's plan participants. The purchase of the annuity contracts were settled by using plan assets. As a result of the settlement, we recognized a pro-rata net actuarial loss of $3.8 million in pension expense and other comprehensive income. The following tables set forth information pertaining to the defined benefit retirement plan: Year Ended December 31, 2018 2017 (Dollars in thousands) Change in benefit obligation: Benefit obligation at beginning of year $ 23,471 $ 23,677 Interest cost 796 926 Actuarial (gains) losses (1,714 ) 752 Benefits paid (1,807 ) (1,884 ) Benefit obligation at end of the year 20,746 23,471 Change in plan assets, at fair value: Fair value of plan assets at beginning of year 22,832 18,539 Actual return on plan assets (1,151 ) 2,177 Employer contributions — 4,000 Benefits paid (1,807 ) (1,884 ) Fair value of plan assets at end of year 19,874 22,832 Funded status at end of year $ (872 ) $ (639 ) Amounts recognized in AOCI: Net actuarial losses $ (8,137 ) $ (8,472 ) Benefit obligation actuarial assumptions: Weighted average discount rate 4.2 % 3.6 % Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Components of net periodic benefit cost: Interest cost $ 796 $ 926 $ 1,374 Expected return on plan assets (1,206 ) (1,036 ) (1,542 ) Amortization of net actuarial losses 979 1,191 1,548 Settlement — — 3,847 Net periodic benefit cost $ 569 $ 1,081 $ 5,227 Net periodic cost actuarial assumptions: Weighted average discount rate 3.6 % 4.1 % 4.3 % Expected long-term rate of return on plan assets 5.5 % 5.5 % 6.0 % The unrecognized net actuarial losses included in AOCI expected to be recognized in net periodic benefit cost during 2019 is approximately $1.0 million . The long-term rate of return on plan assets reflects the weighted-average long-term rates of return for the various categories of investments held in the plan. The expected long-term rate of return is adjusted when there are fundamental changes in expected returns on the plan investments. The defined benefit retirement plan assets consist primarily of equity and debt securities. Our asset allocations by asset category were as follows: December 31, 2018 2017 Equity securities 48.4 % 53.9 % Debt securities 46.9 42.3 Other 4.7 3.8 Total 100.0 % 100.0 % Equity securities included the Company's common stock in the amount of $0.1 million at December 31, 2018 and 2017 . Our investment strategy for the defined benefit retirement plan is to maximize the long-term rate of return on plan assets while maintaining an acceptable level of risk. The investment policy establishes a target allocation for each asset class that is reviewed periodically and rebalanced when considered appropriate. The fair values of the defined benefit retirement plan as of December 31, 2018 and 2017 by asset category were as follows: Quoted Prices Significant Significant Total (Dollars in thousands) December 31, 2018 Money market accounts $ 931 $ — $ — $ 931 Mutual funds 10,537 — — 10,537 Government obligations — 2,192 — 2,192 Common stocks 4,122 — — 4,122 Preferred stocks 146 — — 146 Corporate bonds and debentures — 1,946 — 1,946 Total $ 15,736 $ 4,138 $ — $ 19,874 Quoted Prices Significant Significant Total (Dollars in thousands) December 31, 2017 Money market accounts $ 858 $ — $ — $ 858 Mutual funds 12,258 — — 12,258 Government obligations — 1,942 — 1,942 Common stocks 5,509 — — 5,509 Preferred stocks 176 — — 176 Corporate bonds and debentures — 2,089 — 2,089 Total $ 18,801 $ 4,031 $ — $ 22,832 We are not required by funding regulations or laws to make any contributions to our defined benefit retirement plan in 2019 .

On December 31, 2002, the 1995 and 2001 SERP were curtailed. In conjunction with the merger with CB Bancshares, Inc. ("CBBI"), we assumed CBBI's SERP obligation. In the second quarter of 2017, the Company settled a portion of the SERP obligation of a former executive. As a result of the settlement, the Company remeasured the related SERP obligation and net periodic benefit cost and recognized a pro-rata net actuarial loss of $0.1 million in SERP expense and other comprehensive income. The following tables set forth information pertaining to the SERP: Year Ended December 31, 2018 2017 (Dollars in thousands) Change in benefit obligation Benefit obligation at beginning of year $ 11,219 $ 10,292 Interest cost 389 429 Actuarial (gains) losses (907 ) 1,708 Benefits paid (346 ) (1,210 ) Benefit obligation at end of year 10,355 11,219 Change in plan assets Fair value of plan assets at beginning of year — — Employer contributions 346 1,209 Benefits paid (346 ) (1,209 ) Fair value of plan assets at end of year — — Funded status at end of year $ (10,355 ) $ (11,219 ) Amounts recognized in AOCI Net transition obligation $ (82 ) $ (100 ) Prior service cost (31 ) (49 ) Net actuarial losses (1,082 ) (2,163 ) Total amounts recognized in AOCI $ (1,195 ) $ (2,312 ) Benefit obligation actuarial assumptions Weighted average discount rate 4.2 % 3.5 % Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Components of net periodic benefit cost Interest cost $ 389 $ 429 $ 465 Amortization of net actuarial (gains) losses 174 102 51 Amortization of net transition obligation 18 18 17 Amortization of prior service cost 18 18 18 Settlement — 138 — Net periodic benefit cost $ 599 $ 705 $ 551 Net periodic cost actuarial assumptions Weighted average discount rate 3.5 % 4.1 % 4.4 % The estimated amortization of components included in AOCI that will be recognized into net periodic benefit cost for 2019 is as follows (in thousands): Amortization of net actuarial losses $ 174 Amortization of net transition obligation 18 Amortization of prior service cost 18 The SERP holds no plan assets other than employer contributions that are paid as benefits during the year.

Defined Contribution Plan [Abstract]
401(K) RETIREMENT SAVINGS PLAN	18. 401(K) RETIREMENT SAVINGS PLAN We maintain a 401(k) Retirement Savings Plan ("Retirement Savings Plan") that covers substantially all employees of the Company. The Retirement Savings Plan allows employees to direct their own investments among a selection of investment alternatives and is funded by employee elective deferrals, employer matching contributions and employer profit sharing contributions. We match 100% of an employee's elective deferrals, up to 4% of the employee's pay each pay period. Our employer matching contributions to the Retirement Savings Plan totaled $2.1 million , $2.1 million and $2.0 million in 2018 , 2017 and 2016 , respectively. We also have the option of making discretionary profit sharing contributions into the Retirement Savings Plan. Our Board of Directors has sole discretion in determining the annual profit sharing contribution, subject to limitations of the Internal Revenue Code. We did not make any profit sharing contributions in 2018 , 2017 and 2016 .

OPERATING LEASES	19. OPERATING LEASES We lease certain property and equipment with lease terms expiring through 2045 . In most instances, the property leases provide for the renegotiation of rental terms at fixed intervals, and generally contain renewal options for periods ranging from five to 15 years. Net rent expense for all operating leases for the years ended December 31, 2018 , 2017 and 2016 is summarized as follows: Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Rent expense charged to net occupancy $ 8,578 $ 8,318 $ 8,700 Less: sublease income (41 ) (43 ) (43 ) Net rent expense charged to net occupancy 8,537 8,275 8,657 Add: rent expense charged to equipment expense 12 15 19 Total net rent expense $ 8,549 $ 8,290 $ 8,676 The following is a schedule of future minimum rental commitments for all non-cancellable operating leases that had initial lease terms in excess of one year at December 31, 2018 (in thousands): Year Ending December 31: 2019 $ 6,667 2020 6,083 2021 5,521 2022 4,827 2023 3,203 Thereafter 17,423 Total $ 43,724 In addition, the Company, as lessor, leases certain properties that it owns.

INCOME TAXES	20. INCOME TAXES Components of income tax expense (benefit) for the years ended December 31, 2018 , 2017 and 2016 were as follows: Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Current expense: Federal $ 10,812 $ 2,471 $ 1,850 State 72 (81 ) (4 ) Total current 10,884 2,390 1,846 Deferred expense: Federal 2,137 27,263 19,842 State 5,737 4,943 4,585 Total deferred 7,874 32,206 24,427 Provision for income taxes $ 18,758 $ 34,596 $ 26,273 On December 22, 2017, H.R.1, commonly referred to as the Tax Cuts and Jobs Act (“Tax Reform”) was signed into law making significant changes to the U.S. federal tax code. The most impactful, as related to the Company, included a decrease in the current U.S. federal corporate tax rate from 35% to 21% for the year beginning January 1, 2018. In the year ended December 31, 2017, the Company recorded additional income tax expense of $7.4 million related to the estimated impact of Tax Reform on the Company's net deferred tax assets ("DTA"). In 2018, the Company recorded an income tax benefit of $1.5 million related to the finalization of the impact of Tax Reform, which also included the impact of a tax method change for software development and prepaid expenses that was filed in 2018. Income tax expense (benefit) for the periods presented differed from the "expected" tax expense (computed by applying the U.S. federal corporate tax rate of 21% for the year ended December 31, 2018 and 35% for the years ended December 31, 2017 and 2016, to income (loss) before income taxes) for the following reasons: Year Ended December 31, 2018 2017 2016 (Dollars in thousands) Computed "expected" tax expense (benefit) $ 16,430 $ 26,270 $ 25,260 Increase (decrease) in taxes resulting from: Tax-exempt interest income (808 ) (1,387 ) (1,410 ) Other tax-exempt income (445 ) (1,186 ) (940 ) Low-income housing and energy tax credits 35 (594 ) (129 ) State income taxes, net of Federal income tax effect, excluding impact of deferred tax valuation allowance 4,756 3,348 3,256 Change in the beginning-of-the-year balance of the valuation allowance for deferred tax assets allocated to income tax expense 140 570 (52 ) Impact of Tax Reform on net deferred tax assets (1,542 ) 7,440 — Other, net 192 135 288 Total $ 18,758 $ 34,596 $ 26,273 See Note 1 - Summary of Significant Accounting Policies for discussion of the accounting policy change from the cost method to the proportional amortization method for our LIHTC investments, the effects of which are now reported on the income tax expense line in the consolidated statements of income and are included in the low-income housing and energy tax credits line above. Upon exercise or vesting of a share-based award, if the tax deduction exceeds the compensation cost that was previously recorded for financial statement purposes this will result in an excess tax benefit. ASU 2016-09, “ Compensation-Stock Compensation (718) Improvements to Employee Share-Based Payment Accounting ” requires the Company to recognize all excess tax benefits or tax deficiencies through the income statement as income tax expense/benefit. Under previous GAAP, any excess tax benefits were recognized in additional paid-in capital to offset current-period and subsequent-period tax deficiencies. Effective January 1, 2017, the Company adopted ASU 2016-09. An income tax benefit of $0.1 million and $0.5 million was recorded during the years ended December 31, 2018 and 2017 , respectively, as a result of share awards vesting/exercised during the year. These amounts are included in the Other, net line in the table above. At December 31, 2018 , there was $1.2 million of current federal income tax payable , compared to a $6.7 million receivable at December 31, 2017 . Current state income taxes payable were $72 thousand , compared to a $6 thousand receivable at December 31, 2018 and 2017 , respectively. The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows: December 31, 2018 2017 (Dollars in thousands) Deferred tax assets Allowance for loan and lease losses $ 10,112 $ 10,622 Accrued expenses 1,517 294 Employee retirement benefits 2,595 2,784 Federal and state tax credit carryforwards 7,728 12,473 State net operating loss carryforwards 3,291 3,306 Restricted stock and non-qualified stock options 1,001 661 Premises and equipment 3,157 3,633 Other 3,485 3,169 Total deferred tax assets 32,886 36,942 Deferred tax liabilities Intangible assets 4,189 4,785 Other 3,698 2,343 Total deferred tax liabilities 7,887 7,128 Less: Deferred tax valuation allowance 3,461 3,321 Net deferred tax assets $ 21,538 $ 26,493 In assessing the realizability of our net DTA, management considers whether it is more likely than not that some portion or all of the DTA will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income and tax-planning strategies in making this assessment. As of December 31, 2018 , the valuation allowance on our net DTA totaled $3.5 million , of which $3.3 million related to our DTA from net apportioned net operating loss ("NOL") carryforwards for California state income tax purposes as we do not expect to generate sufficient income in California to utilize the DTA. The remaining $0.2 million relates to a valuation allowance on a Hawaii capital loss carry forward balance of $4.9 million that we do not expect to be able to utilize. The net change in the valuation allowance was an increase of $0.1 million in 2018 , compared to an increase of $0.6 million in 2017 . Net of this valuation allowance, the Company's net DTA totaled $21.5 million as of December 31, 2018 , compared to a net DTA of $26.5 million as of December 31, 2017 . At December 31, 2018 , the Company had NOL carryforwards for California state income tax purposes of $38.4 million , which are available to offset future state taxable income. California NOL carryforwards will expire if unutilized beginning in 2028. The Company does not have any NOL carryforwards for U.S. federal or Hawaii state income tax purposes. In addition, we have gross Hawaii state tax credit carryforwards of $10.6 million that do not expire. In 2018, we utilized the remainder of our federal tax credit carryforwards. At December 31, 2018 , we have no unrecognized tax benefits that, if recognized would favorably affect the effective income tax rate in future periods. We do not expect our unrecognized tax benefits to change significantly over the next 12 months. We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. Taxable years through 2014 are closed.

CONTINGENT LIABILITIES AND OTHER COMMITMENTS	23. CONTINGENT LIABILITIES AND OTHER COMMITMENTS The Company and its subsidiaries are involved in legal actions arising in the ordinary course of business. Management, after consultation with legal counsel, believes the ultimate disposition of those matters will not have a material adverse effect on our consolidated financial statements. In the normal course of business there are outstanding contingent liabilities and other commitments such as unused letters of credit and items held for collections, which are not reflected in the accompanying consolidated financial statements. Management does not anticipate any material losses as a result of these transactions.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK	24. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees written, forward foreign exchange contracts, and interest rate contracts. Those instruments involve, to varying degrees, elements of credit, interest rate and foreign exchange risk in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments. Our exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit and standby letters of credit and financial guarantees written is represented by the contractual amount of those instruments. For forward foreign exchange contracts and interest rate contracts, the contract amounts do not represent exposure to credit loss. We control the credit risk of these contracts through credit approvals, limits and monitoring procedures. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. These derivatives are carried at fair value with changes in fair value recorded as a component of other operating income in the consolidated statements of income. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties. Standby letters of credit and financial guarantees written are conditional commitments issued by us to guarantee the performance of a customer to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. We hold collateral supporting those commitments for which collateral is deemed necessary. Interest rate options issued on residential mortgage loans expose us to interest rate risk, which is economically hedged with forward interest rate contracts. These derivatives are carried at fair value with changes in fair value recorded as a component of other operating income in the consolidated statements of income. The amount of interest rate options fluctuates based on residential mortgage volume. Forward interest rate contracts represent commitments to purchase or sell loans at a future date at a specified price. We enter into forward interest rate contracts on our residential mortgage held for sale loans. These derivatives are carried at fair value with changes in fair value recorded as a component of other operating income in the consolidated statements of income. Risks arise from the possible inability of counter-parties to meet the terms of their contracts and from movements in market rates. Management reviews and approves the creditworthiness of the counterparties to its forward interest rate contracts. Forward foreign exchange contracts represent commitments to purchase or sell foreign currencies at a future date at a specified price. These derivatives are carried at fair value with changes in fair value recorded as a component of other operating income in the consolidated statements of income. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movements in foreign currency exchange rates. Management reviews and approves the creditworthiness of its forward foreign exchange counterparties. At December 31, 2018 and 2017 , we did not have any forward foreign exchange contracts. At December 31, 2018 and 2017 , financial instruments with off-balance sheet risk were as follows: December 31, 2018 2017 (Dollars in thousands) Notional amount of: Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 1,030,322 $ 917,405 Standby letters of credit and financial guarantees written 13,377 13,551 Notional amount of: Financial instruments whose contract amounts exceed the amount of credit risk: Interest rate options 2,158 2,494 Forward interest rate contracts 8,530 18,748

Fair Value Disclosures [Abstract]
FAIR VALUE OF ASSETS AND LIABILITIES	25. FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL 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 financial institutions, interest-bearing deposits in other financial institutions, accrued interest receivable, the majority of Federal Home Loan Bank advances and other 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 December 31, 2018 are based on the notion of exit price. The fair value of loans as of December 31, 2017 was measured based on the notion of entry price. 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. Federal Home Loan Bank Stock It is not practical to determine the fair value of FHLB stock due to the restrictions placed on its transferability. 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. Derivatives The fair values of derivative financial instruments 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. 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. 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 core deposit premium.

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 and mortgage servicing rights. 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 year ended December 31, 2018 . The following table below presents the the fair value of assets and liabilities measured on a recurring basis: Fair Value at Reporting Date Using Fair Quoted Prices Significant Significant (Dollars in thousands) December 31, 2018 Available for sale securities: Debt securities: States and political subdivisions $ 173,674 $ — $ 162,505 $ 11,169 Corporate securities 54,849 — 54,849 — U.S. Treasury obligations and direct obligations of U.S Government agencies 32,574 — 32,574 — Mortgage-backed securities: Residential - U.S. Government-sponsored entities ("GSEs") 717,052 — 717,052 — Residential - Non-government sponsored entities ("Non-GSEs") 41,118 — 41,118 — Commercial - U.S. GSEs and agencies 51,483 — 51,483 — Commercial - Non-GSEs 134,728 — 134,728 — Equity securities 826 826 — — Derivatives: Interest rate lock and forward sale commitments (84 ) — (84 ) — Total $ 1,206,220 $ 826 $ 1,194,225 $ 11,169 Fair Value at Reporting Date Using Fair Quoted Prices Significant Significant (Dollars in thousands) 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 ("GSEs") 800,683 — 800,683 — Residential - Non-government sponsored entities ("Non-GSEs") 46,763 — 46,763 — Commercial - U.S. GSEs and agencies 39,725 — 39,725 — Commercial - Non-GSEs 137,326 — 137,326 — Equity securities 825 825 — — Derivatives: Interest rate lock and forward sale commitments (14 ) — (14 ) — Total $ 1,304,877 $ 825 $ 1,292,258 $ 11,794 The changes in Level 3 assets and liabilities measured at fair value on a recurring basis are summarized as follows: Available for Sale (Dollars in thousands) Balance as of December 31, 2016 $ 12,196 Principal payments received (358 ) Purchases — Unrealized net loss included in other comprehensive loss (44 ) Balance as of December 31, 2017 $ 11,794 Principal payments received (373 ) Purchases — Unrealized net loss included in other comprehensive loss (252 ) Balance as of December 31, 2018 $ 11,169 Within the state and political subdivisions debt securities category, the Company holds four mortgage revenue bonds issued by the City and County of Honolulu with an aggregate fair value of $11.2 million and $11.8 million at December 31, 2018 and 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 December 31, 2018 , the weighted average discount rate utilized was 5.06% , 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.

Segment Reporting [Abstract]
SEGMENT INFORMATION	26. SEGMENT INFORMATION We have the following three reportable segments: Banking Operations, Treasury and All Others. The segments are consistent with our internal functional reporting lines and are managed separately because each unit has different target markets, technological requirements, marketing strategies and specialized skills. The Banking Operations segment includes construction and real estate development lending, commercial lending, residential mortgage lending, consumer 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 includes 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 those described in Note 1 - Summary of Significant Accounting Policies . 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.

Condensed Financial Information of Parent Company Only Disclosure [Abstract]
PARENT COMPANY AND REGULATORY RESTRICTIONS	27. PARENT COMPANY AND REGULATORY RESTRICTIONS At December 31, 2018 , the accumulated deficit of the parent company, Central Pacific Financial Corp., included $435.0 million of equity in undistributed losses of Central Pacific Bank. Central Pacific Bank, as a Hawaii state-chartered 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 December 31, 2018 , the bank had Statutory Retained Earnings of $46.6 million . For further information, see Note 13 - Equity . The Company and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks ("Basel III rules") became effective for the Company on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a "capital conservation buffer" above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in at the rate of 0.625% per year from 0.625% in 2016 to 2.50% on January 1, 2019. The capital conservation buffer for 2018 is 1.875% and for 2017 is 1.25% . The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2018, the Company and Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well-capitalized, adequately capitalized, under-capitalized, significantly under-capitalized, and critically under-capitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If under-capitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end 2018 and 2017, the most recent regulatory notifications categorized the Bank as "well-capitalized" under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. The following table sets forth actual and required capital and capital ratios for the Company and the bank, as well as the minimum capital adequacy requirements applicable generally to all financial institutions as of the dates indicated.

When fully phased-in on January 1, 2019, the Basel III rules will include a CCB of 2.5% that is added on top of each of the minimum risk-based capital ratios noted above (excluding the leverage ratio). The CCB is being phased in at the rate of 0.625% per year from 0.625% in 2016 to 2.50% on January 1, 2019.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles of Consolidation	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 met the consolidation requirements under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 810, " Consolidation ". The bank also concluded that the entity met the definition of a variable interest entity and that we were the primary beneficiary of the variable interest entity. Accordingly, the investment has been consolidated into our financial statements as of December 31, 2017 and 2016. One Hawaii HomeLoans, LLC was terminated in 2017, and final payment of taxes and distributions to members was made in March 2018. We have 50% ownership interests in four other mortgage loan origination and brokerage companies which are accounted for using the equity method and are included in investment in unconsolidated subsidiaries: Pacific Access Mortgage, LLC, Gentry HomeLoans, LLC, Haseko HomeLoans, LLC and Island Pacific HomeLoans, LLC. Pacific Access Mortgage, LLC was terminated in 2017, and final payment of taxes and distributions to members was made in March 2018. As previously discussed we have LIHTC investments that are now accounted for under the proportional amortization method and are included in investment in unconsolidated subsidiaries. We also have non-controlling equity investments in affiliates that are accounted for under the cost method and are also included in investment in unconsolidated subsidiaries. Our investments in unconsolidated subsidiaries accounted for under the equity, proportional amortization and cost methods were $0.2 million , $11.6 million and $2.2 million , respectively, at December 31, 2018 and $0.6 million , $3.6 million and $2.8 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.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions that reflect the reported amounts of assets and liabilities and disclosures of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance and provision for loan and lease losses, reserves for unfunded loan commitments, deferred income tax assets and income tax expense, valuation of investment securities, mortgage servicing rights and the related amortization thereon, pension liability and the fair value of certain financial instruments.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and due from financial institutions, interest-bearing deposits in other financial institutions, federal funds sold and all highly liquid investments with maturities of three months or less at the time of purchase. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and federal funds purchased and repurchase agreements.
Investment Securities	Investment Securities Investments in debt securities and mortgage-backed securities are designated as trading, available-for-sale, or held-to-maturity. Securities are designated as held-to-maturity only if we have the positive intent and ability to hold these securities to maturity. Held-to-maturity securities are reported at amortized cost. Trading securities are reported at fair value, with changes in fair value included in net income. Available-for-sale securities are reported at fair value, with net unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) ("AOCI"). Equity securities with readily determinable fair values are carried at fair value, with changes in fair value included in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Interest income on investment securities includes amortization of premiums and accretion of discounts. We amortize premiums to the earliest call date. We accrete discounts associated with investment securities using the interest method over the life of the respective security instrument. Management evaluates investment securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation, to determine whether the unrealized losses on investment securities, or the decline in their value below amortized cost is "other-than-temporary." The term other-than-temporary is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. In conducting this assessment, for debt securities in an unrealized loss position 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 decline in fair value subsequent to the balance sheet date. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the decline in value is determined to be other-than-temporary, the value of the security is reduced and a corresponding impairment charge to earnings is recognized for anticipated credit losses. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. The declines in market value were primarily attributable to changes in interest rates and volatility in the credit and financial markets. 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. We are a member of the Federal Home Loan Bank of Des Moines (the "FHLB"). The bank is required to obtain and hold a specific number of shares of capital stock of the FHLB equal to the sum of a membership investment requirement and an activity-based investment requirement. The securities are reported at cost and are presented separately in the consolidated balance sheets.
Loans Held for Sale	Loans Held for Sale Loans held for sale consists of the following two types: (1) Hawaii residential mortgage loans that are originated with the intent to sell them in the secondary market and (2) non-residential mortgage loans in both Hawaii and the U.S. Mainland that were originated with the intent to be held in our portfolio but were subsequently transferred to the held for sale category. Hawaii residential mortgage loans classified as held for sale are carried at the lower of cost or fair value on an aggregate basis, while the non-residential Hawaii and U.S. Mainland loans are recorded at the lower of cost or fair value on an individual basis. Net fees and costs associated with originating and acquiring the Hawaii residential mortgage loans held for sale are deferred and included in the basis for determining the gain or loss on sales of loans held for sale. We report the fair values of the non-residential mortgage loans classified as held for sale net of applicable selling costs on our consolidated balance sheets. Loans originated with the intent to be held in our portfolio are subsequently transferred to held for sale when our intent to hold for the foreseeable future has changed. At the time of a loan's transfer to the held for sale account, the loan is recorded at the lower of cost or fair value. Any reduction in the loan's value is reflected as a write-down of the recorded investment resulting in a new cost basis, with a corresponding reduction in the allowance for loan and lease losses. In subsequent periods, if the fair value of a loan classified as held for sale is less than its cost basis, a valuation adjustment is recognized in our consolidated statement of income in other operating expense and the carrying value of the loan is adjusted accordingly. The valuation adjustment may be recovered in the event that the fair value increases, which is also recognized in our consolidated statement of income in other operating expense. 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. Collateral values are determined based on appraisals received from qualified valuation professionals and are obtained periodically or when indicators that property values may be impaired are present. We sell residential mortgage loans under industry standard contractual provisions that include various representations and warranties, which typically cover ownership of the loan, compliance with loan criteria set forth in the applicable agreement, validity of the lien securing the loan, and other similar matters. We may be required to repurchase certain loans sold with identified defects, indemnify the investor, or reimburse the investor for any credit losses incurred. Our repurchase risk generally relates to early payment defaults and borrower fraud. We establish residential mortgage repurchase reserves to reflect this risk based on our estimate of losses after considering a combination of factors, including our estimate of future repurchase activity and our projection of incurred credit losses resulting from repurchased loans.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the principal amount outstanding, net of deferred loan fees (costs). Net deferred loan fees (costs) are recognized over the life of the related loan as an adjustment to yield and are amortized using the interest method over the contractual term of the loan, adjusted for actual prepayments. Unamortized fees (costs) on loans paid in full are recognized as a component of interest income. Interest income on loans is recognized on an accrual basis. 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. Loans are placed on nonaccrual status when interest payments are 90 days past due, or earlier should management determine that the borrowers will be unable to meet contractual principal and/or interest obligations, unless the loans are well-secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income should management determine that the collectibility of such accrued interest is doubtful. All subsequent receipts are applied to principal outstanding and no interest income is recognized unless the financial condition and payment record of the borrowers warrant such recognition. A nonaccrual loan may be restored to an accrual basis when principal and interest payments are current and full payment of principal and interest is expected.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses The allowance for loan and lease losses (the "Allowance") is a valuation allowance established through provisions for loan and lease losses (the "Provision") charged against income. Our policy is to charge a loan off in the period in which the loan is deemed to be uncollectible and all interest previously accrued but not collected is reversed against current period interest income. We consider a loan to be uncollectible when it is probable that a loss has been incurred and the Company can make a reasonable estimate of the loss. In these instances, the likelihood of and/or timeframe for recovery of the amount due is uncertain, weak, or protracted. Subsequent receipts, if any, are credited first to the remaining principal, then to the Allowance as recoveries, and finally to unaccrued interest. The Allowance is management's estimate of incurred credit losses inherent in our loan and lease portfolio at the balance sheet date. In determining the amount of our Allowance, we rely on an analysis of our loan portfolio, our experience and our evaluation of general economic conditions, as well as regulatory requirements. We maintain our Allowance at an amount we expect to be sufficient to absorb probable losses inherent in our loan and lease portfolio based on a projection of probable net loan charge-offs. The Company's approach to developing the Allowance has three basic elements. These elements include specific reserves for individually impaired loans, a general allowance for loans other than those analyzed as individually impaired, and qualitative adjustments based on environmental and other factors which may be internal or external to the Company. These three elements are explained below. Specific Reserve Individually impaired loans in all loan categories are evaluated using one of three valuation methods as prescribed under Accounting Standards Codification ("ASC") 310-10, Fair Value of Collateral, Observable Market Price, or Cash Flow . A loan is generally evaluated for impairment on an individual basis if it meets one or more of the following characteristics: risk-rated as substandard, doubtful or loss, loans on nonaccrual status, troubled debt restructures, or any loan deemed prudent by management to so analyze. If the valuation of the impaired loan is less than the recorded investment in the loan, the deficiency will be charged off against the Allowance or, alternatively, a specific reserve will be established and included in the overall Allowance balance. General Allowance In determining the general allowance component of the Allowance, the Company utilizes a comprehensive approach to segment the loan portfolio into homogeneous groups. The Company's methodology segments the portfolio generally by FDIC Call Report codes in eleven segments, and is consistent with general industry practice. For the purpose of determining general allowance loss factors, loss experience is derived from a migration analysis, with the exception of national syndicated loans and auto dealer purchased loans where an average historical loss rate is applied due to limited historical loss experience. The key inputs to run a migration analysis are the length of the migration period, the dates for the migration periods to start and the number of migration periods used for the analysis. For each migration period, the analysis will determine the outstanding balance in each segment and/or sub-segment at the start of each period. These loans will then be followed for the length of the migration period to identify the amount of associated charge-offs and recoveries. A loss rate for each migration period is calculated using the formula ‘net charge-offs over the period divided by beginning loan balance'. The Allowance methodology applies a look back period to January 1, 2010. The Company extends its look back period with each additional quarter passing. As of December 31, 2018 , the look back period was nine years. Qualitative Adjustments Our Allowance methodology uses qualitative adjustments to address changes in conditions, trends, and circumstances such as economic conditions and industry changes that could have a significant impact on the risk profile of the loan portfolio, and provide for losses in the loan portfolio that may not be reflected and/or captured in the historical loss data. In order to ensure that the qualitative adjustments are in compliance with current regulatory standards and U.S. GAAP, the Company is primarily basing adjustments on the nine standard factors outlined in the 2006 Interagency Policy Statement on the Allowance for Loan and Lease Losses. These factors include: lending policies, economic conditions, loan profile, lending staff, problem loan trends, loan review, collateral, credit concentrations and other internal and external factors. In recognizing that current and relevant environmental (economic, market or other) conditions that can affect repayment may not yet be fully reflected in historical loss experience, qualitative adjustments are applied to factor in current loan portfolio and market intelligence. These adjustments, which are added to the historical loss rate, consider the nature of the Company's primary markets and are reasonable, consistently determined and appropriately documented. Management reviews the results of the qualitative adjustment quarterly to ensure it is consistent with the trends in the overall economy, and from time to time may make adjustments, if necessary, to ensure directional consistency.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments Our process for determining the reserve for unfunded loan commitments utilizes historical loss rates and is adjusted for estimated loan funding probabilities. The reserve for unfunded loan commitments is recorded separately through a valuation allowance included in other liabilities. Credit losses for off-balance sheet credit exposures are deducted from the allowance for credit losses on off-balance sheet credit exposures in the period in which the liability is settled. The allowance for credit losses on off-balance sheet credit losses is established by a charge to other operating expense.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are included in other operating expense and are computed using the straight-line method over the shorter of the estimated useful lives of the assets or the applicable leases. Useful lives generally range from five to thirty-nine years for premises and improvements, and one to seven years for equipment. Major improvements and betterments are capitalized, while recurring maintenance and repairs are charged to operating expense. Net gains or losses on dispositions of premises and equipment are included in other operating income and operating expense.
Other Intangible Assets	Core Deposit Premium and Mortgage Servicing Rights Our core deposit premium was amortized over 14 years which approximated the estimated life of the purchased deposits. 2018 was the final year of amortization. The carrying value of our core deposit premium was periodically evaluated to estimate the remaining periods of benefit. If these periods of benefit were determined to be less than the remaining amortizable life, an adjustment to reflect such shorter life would have been made. Mortgage servicing rights are recorded when loans are sold to third-parties with servicing of those loans retained and we classify and pool our mortgage servicing rights into buckets of homogeneous characteristics. We utilize the amortization method to measure our mortgage servicing rights. Under the amortization method, we amortize our mortgage servicing rights in proportion to and over the period of net servicing income. Income generated as the result of new mortgage servicing rights is reported as gains on sales of loans and is a component of mortgage banking income in the other operating income section of our consolidated statements of income. Amortization of the servicing rights is also reported as a component of mortgage banking income. Ancillary income is recorded in other income. 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 and 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, servicing cost and ancillary income. 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. Prepayment speeds may be affected by economic factors such as home price appreciation, market interest rates, the availability of other credit products to our borrowers and customer payment patterns. Prepayment speeds include the impact of all borrower prepayments, including full payoffs, additional principal payments and the impact of loans paid off due to foreclosure liquidations. We perform an impairment assessment of our mortgage servicing rights quarterly or whenever events or changes in circumstance indicate that the carrying value of those assets may not be recoverable. Our impairment assessments involve, among other valuation methods, the estimation of future cash flows and other methods of determining fair value. Estimating future cash flows and determining fair values is subject to judgments and often involves the use of significant estimates and assumptions. The variability of the factors we use to perform our impairment tests depend on a number of conditions, including the uncertainty about future events and cash flows. All such factors are interdependent and, therefore, do not change in isolation. Accordingly, our accounting estimates may materially change from period to period due to changing market factors.
Other Real Estate	Other Real Estate Other real estate is composed of properties acquired through foreclosure proceedings and is initially recorded at fair value less estimated costs to sell the property, thereby establishing the new cost basis of other real estate. Losses arising at the time of acquisition of such properties are charged against the Allowance. Subsequent to acquisition, such properties are carried at the lower of cost or fair value less estimated selling expenses, determined on an individual asset basis. Any deficiency resulting from the excess of cost over fair value less estimated selling expenses is recognized as a valuation allowance. Any subsequent increase in fair value up to its cost basis is recorded as a reduction of the valuation allowance. Increases or decreases in the valuation allowance are included in other operating expense. Net gains or losses recognized on the sale of these properties are included in other operating income.
Non-Controlling Interest	Non-Controlling Interest Non-controlling interest was comprised of capital and undistributed profits of the member of One Hawaii HomeLoans, LLC, other than the bank. Non-controlling interest on our consolidated balance sheet at December 31, 2018 and December 31, 2017 totaled $0 and $24 thousand , respectively.
Share Based Compensation	Share-Based Compensation Share-based compensation cost is measured at the grant date, based on the estimated fair value of the award. We use the Black-Scholes option-pricing model to determine the fair-value of stock options, and the market price of the Company's common stock at the grant date for restricted stock awards. Share-based compensation is recognized as expense over the employee's requisite service period, generally defined as the vesting period. For awards with graded vesting, we recognize compensation expense on a straight-line basis over their respective vesting period. The Company's accounting policy is to recognize forfeitures as they occur. See Note 16 - Share-Based Compensation for further discussion of our stock-based compensation.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax effects attributable to temporary differences and carryforwards. A valuation allowance may be required if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. In determining whether a valuation allowance is necessary, we consider the level of taxable income in prior years, to the extent that carrybacks are permitted under current tax laws, as well as estimates of future taxable income and tax planning strategies that could be implemented to accelerate taxable income, if necessary. If our estimates of future taxable income were materially overstated or if our assumptions regarding the tax consequences of tax planning strategies were inaccurate, some or all of our deferred tax assets may not be realized, which would result in a charge to earnings. We recognize interest and penalties related to income tax matters in other expense. We establish income tax contingency reserves for potential tax liabilities related to uncertain tax positions. Tax benefits are recognized when we determine that it is more likely than not that such benefits will be realized. Where uncertainty exists due to the complexity of income tax statutes, and where the potential tax amounts are significant, we generally seek independent tax opinions to support our positions. If our evaluation of the likelihood of the realization of benefits is inaccurate, we could incur additional income tax and interest expense that would adversely impact earnings, or we could receive tax benefits greater than anticipated which would positively impact earnings.
Earnings per Share	Earnings per Share Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding unvested restricted stock awards. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, increased by the dilutive effect of stock options and stock awards, less shares held in a Rabbi trust pursuant to a deferred compensation plan for directors.
Forward Foreign Exchange Contracts	Forward Foreign Exchange Contracts We are periodically a party to a limited amount of forward foreign exchange contracts to satisfy customer needs for foreign currencies. These contracts are not utilized for trading purposes and are carried at market value, with realized gains and losses included in fees on foreign exchange.
Derivatives and Hedging Activities	Derivatives and Hedging Activities We recognize all derivatives on the balance sheet at fair value. On the date that we enter into a derivative contract, we designate the derivative as (1) a hedge of the fair value of an identified asset or liability ("fair value hedge"), (2) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to an identified asset or liability ("cash flow hedge") or (3) a transaction not qualifying for hedge accounting ("free standing derivative"). For a fair value hedge, changes in the fair value of the derivative and, to the extent that it is effective, changes in the fair value of the hedged asset or liability, attributable to the hedged risk, are recorded in current period net income in the same financial statement category as the hedged item. For a cash flow hedge, changes in the fair value of the derivative, to the extent that it is effective, is recorded in other comprehensive income (loss) ("OCI"). These changes in fair value are subsequently reclassified to net income in the same period(s) that the hedged transaction affects net income in the same financial statement category as the hedged item. For free standing derivatives, changes in fair values are reported in current period other operating income.
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 $0.6 million during the year ended December 31, 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 14 - 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 as of December 31, 2018 , from available-for-sale investment securities to equity investment securities on the Company's consolidated balance sheets. 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 are now recognized in net income. The Company's equity investment securities portfolio of $0.8 million as of December 31, 2017 has also been reclassified from available-for-sale investment securities to equity investment securities on the consolidated balance sheets to conform to the current year's presentation. 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 25 - Fair Value of Financial Assets and Financial 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 have a material impact on the Company's financial statements. 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. Although ASU 2017-08 is effective for the Company's reporting period beginning on January 1, 2019, the Company elected to early adopt the standard effective January 1, 2018. The amendments in ASU 2017-08 did not have a material impact to 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 is 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 loss on the Company's investment securities portfolio by $1.4 million and $0.5 million , respectively. Impact of Other Recently Issued Accounting Pronouncements on Future Filings In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842) . " ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU establishes a right-of-use ("ROU") model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term of longer than 12 months. The FASB has also made available several practical expedients to assist entities with the adoption of ASU 2016-02. Among other things, these practical expedients require no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for current leases. In July 2018, the FASB released ASU 2018-11, "Leases (Topic 842 Targeted Improvements)," which adds an additional practical expedient that allows entities to elect not to recast comparative periods presented when transitioning to Topic 842. During the year ended December 31, 2018 , the Company engaged a software vendor to assist in the implementation of ASU 2016-02. The ASU is effective for the Company's reporting period beginning January 1, 2019. As of January 1, 2019, the Company adopted ASU 2016-02 using the modified retrospective approach and has recorded a ROU asset and lease liability of $55.9 million on the balance sheet for its operating leases where it is a lessee. There was no effect on the Company's leases as lessor. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , " which significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s “incurred loss” guidance delays the recognition of credit losses on loans, leases, held-to-maturity debt securities, loan commitments, and financial guarantees, and instead provides for a current expected credit loss (“CECL”) approach to determine the allowance for credit losses. CECL requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, this guidance modifies the accounting treatment for other-than-temporary impairment for available-for-sale debt securities. Organizations will continue to use judgment to determine which loss estimation methods are appropriate for their circumstances. This guidance requires entities to record a cumulative effect adjustment to the consolidated balance sheet as of the beginning of the first reporting period in which the guidance is effective. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted. As such, the Company will implement CECL for the reporting period beginning January 1, 2020. The new guidance will require significant operational changes, particularly in data collection and analysis. The Company has formed a steering committee that is responsible for oversight of the Company’s implementation strategy for compliance with provisions of the new standard. The Company has also established a project management governance process to manage the implementation across affected disciplines. An external provider specializing in community bank loss driver and CECL reserving model design as well as other related consulting services has been retained, and we have begun to evaluate potential CECL modeling alternatives. As part of this process, the Company has determined loan pool segmentation and sub-segmentation under CECL, as well as evaluated the key economic loss drivers for each segment. Further, the Company has engaged a third party economic forecasting service to utilize in developing the Company's reasonable and supportable forecasts under CECL. Finally, the Company has begun developing internal controls around the CECL process, data, calculations and implementation. The Company presently plans to generate and evaluate model scenarios under CECL in tandem with its current reserving processes for interim and annual reporting periods in 2019. While the Company is currently unable to reasonably estimate the impact of adopting this new guidance, management expects the impact of adoption will be significantly influenced by the composition and quality of the Company’s loans and investment securities as well as the economic conditions as of the date of adoption. The Company also anticipates significant changes to the processes and procedures for calculating the reserve for credit losses and continues to evaluate the potential impact on our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 was issued to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The FASB believes that such amendments will: 1) improve the transparency of information about an entity’s risk management activities and 2) simplify the application of hedge accounting. The ASU allows an entity that qualifies for the last-of-layer method to reclassify securities from the held-to-maturity category to the available-for-sale category. The ASU is effective for the the Company's reporting period beginning on January 1, 2019. As of January 1, 2019, the Company adopted ASU 2017-12 and has transferred all of its held-to-maturity securities to available-for-sale. The ASU did not have a material impact on our current derivative activities. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The ASU is part of the FASB's disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by generally accepted accounting principles. The ASU modifies disclosure requirements on fair value measurements in Topic 820, specifically requiring more information be disclosed on the significant unobservable inputs used to develop Level 3 fair value measurements. The ASU is effective for the Company's reporting period beginning January 1, 2020. Early adoption is permitted. Based on preliminary evaluation, the ASU will not have a material impact on disclosures in our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans." Like ASU 2018-13, this ASU is part of the FASB's disclosure framework project. This ASU modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU is effective for the Company's reporting period beginning January 1, 2021. Early adoption is permitted. Based on preliminary evaluation, the ASU will not have a material impact on disclosures in our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," which requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for the Company's reporting period beginning January 1, 2020 and early adoption is permitted. We are currently in the process of evaluating the potential impact the amendments will have on our consolidated financial statements, but we do not expect the adoption of the ASU to have a material impact on our consolidated financial statements. Reclassifications In addition to the reclassifications related to our investments in LIHTC partnerships discussed above, the Company's equity investment securities in the prior year have been reclassified from available-for-sale investment securities on the consolidated balance sheets to conform to the current year's presentation in accordance with ASU 2016-01, "Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Liabilities . " The reclassification had no impact on the Company's reported net income or shareholders' equity.

REVENUE FROM CONTRACTS WITH C_2

REVENUE FROM CONTRACTS WITH CUSTOMERS (Policies)	12 Months Ended
	Dec. 31, 2018
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. Fees on Foreign Exchange The Company provides foreign currency exchange services to customers, whereby cash can be converted to different foreign currencies, and vice versa. As a result of the services, a gain or loss is recognized on foreign currency transactions, as well as income related to commissions and fees earned on each transaction. Revenue from the commissions and fees earned on the transactions fall within the scope of ASC 606, and is recorded in a manner that reflects the timing of when transactions occur, and as services are provided. Realized and unrealized gains or losses related to foreign currency are out of scope of ASC 606. 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. Gain on Sales of Foreclosed Assets The Company records a gain or loss on the sale of a foreclosed property when control of the property transfers to the Company, which typically occurs at the time the deed is executed. The Company does not finance the sale of the foreclosed property.
