Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business: Fulton Financial Corporation ("Corporation" or "Parent Company") is a financial holding company which provides a full range of banking and financial services to businesses and consumers through its wholly owned banking subsidiary, Fulton Bank, N.A. ("Fulton Bank" or the "Bank"). In addition, the Parent Company owns the following non-bank subsidiaries: Fulton Financial Realty Company, Central Pennsylvania Financial Corp., FFC Management, Inc., FFC Penn Square, Inc. and Fulton Insurance Services Group, Inc. Collectively, the Parent Company and its subsidiaries are referred to as the Corporation. The Corporation’s primary sources of revenue are interest income on loans, investment securities and other interest-earning assets and fee income earned on its products and services. Its expenses consist of interest expense on deposits and borrowed funds, provision for credit losses, other operating expenses and income taxes. The Corporation’s primary competition is other financial services providers operating in its region. Competitors also include financial services providers located outside the Corporation’s geographic market as a result of the growth in electronic delivery channels. The Corporation is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by such regulatory authorities. The Corporation offers, through its banking subsidiary, a full range of retail and commercial banking services in Pennsylvania, Delaware, Maryland, New Jersey and Virginia. Industry diversity is the key to the economic well-being of these markets and the Corporation is not dependent upon any single customer or industry. In 2017, the Corporation had six banking subsidiaries. During 2018, the Corporation consolidated two of its wholly owned banking subsidiaries into its lead bank, Fulton Bank, and during 2019 , the remaining three wholly-owned banking subsidiaries were consolidated into Fulton Bank. Basis of Financial Statement Presentation: The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") and include the accounts of the Parent Company and all wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosed amount of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. The Corporation evaluates subsequent events through the date of the filing of this report with the Securities and Exchange Commission ("SEC"). Cash and Cash Equivalents and Restricted Cash: Cash and cash equivalents consists of cash and due from banks and interest bearing deposits with other banks, which includes restricted cash. Restricted cash comprises cash balances required to be maintained with the Federal Reserve Bank ("FRB"), based on customer transaction deposit account levels, and cash balances provided as collateral on derivative contracts and other contracts. See Note 2, "Restrictions on Cash and Cash Equivalents" for additional information. FRB and FHLB Stock: The Bank is a member of the FRB and FHLB and is required by federal law to hold stock in these institutions according to predetermined formulas. These restricted investments are carried at cost on the consolidated balance sheets and are periodically evaluated for impairment. Investments: Debt securities are classified as held to maturity ("HTM") at the time of purchase when the Corporation has both the intent and ability to hold these investments until they mature. Such debt securities are carried at cost, adjusted for amortization of premiums and accretion of discounts using the effective yield method. The Corporation does not engage in trading activities; however, since the investment portfolio serves as a source of liquidity, most debt securities are classified as available for sale ("AFS"). AFS securities are carried at estimated fair value with the related unrealized holding gains and losses reported in shareholders’ equity as a component of other comprehensive income, net of tax. Realized securities gains and losses are computed using the specific identification method and are recorded on a trade date basis. Securities are evaluated periodically to determine whether declines in value are other-than-temporary. Impaired debt securities are determined to be other-than-temporarily impaired if the Corporation concludes at the balance sheet date that it has the intent to sell, or believes it will more likely than not be required to sell, an impaired debt security before a recovery of its amortized cost basis. Credit losses on other-than-temporarily impaired debt securities are recorded through earnings, regardless of the intent or the requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s expected cash flows and its amortized cost. Non-credit related other-than-temporary impairment ("OTTI") charges are recorded as decreases to accumulated other comprehensive income as long as the Corporation has no intent or expected requirement to sell the impaired debt security before a recovery of its amortized cost basis. The Corporation early adopted ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivative and Hedging, and Topic 825, Financial Instruments," in the third quarter of 2019, which permitted the one-time reclassification of certain HTM securities to AFS under Topic 815, specific to the transition guidance of ASU update 2017-12, which the Corporation adopted on January 1, 2019. See “Note 3 - Investment Securities” for additional information on this reclassification. The portion of this standards update related to codification improvements specific to Topic 326 will be implemented upon the Corporation’s adoption of ASU 2016-13 in the first quarter of 2020. Additional codification improvements to Topic 825, specifically ASU 2016-01, which the Corporation adopted as of January 1, 2018, did not have an impact on the Corporation's consolidated financial statements. Fair Value Option: The Corporation has elected to measure mortgage loans held for sale at fair value. Derivative financial instruments related to mortgage banking activities are also recorded at fair value, as detailed under the heading "Derivative Financial Instruments," below. The Corporation determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair values during the period are recorded as components of mortgage banking income on the consolidated statements of income. Interest income earned on mortgage loans held for sale is classified in interest income on the consolidated statements of income. Loans and Lease Receivables : Loan and leases are stated at their principal amount outstanding, except for mortgage loans held for sale, which are carried at fair value. Interest income on loans is accrued as earned. Unearned income on lease financing receivables is recognized on a basis which approximates the effective yield method. In general, a loan or lease is placed on non-accrual status once it becomes 90 days delinquent as to principal or interest. In certain cases a loan or lease may be placed on non-accrual status prior to being 90 days delinquent if there is an indication that the borrower is having difficulty making payments, or the Corporation believes it is probable that all amounts will not be collected according to the contractual terms of the loan or lease agreement. When interest accruals are discontinued, unpaid interest previously credited to income is reversed. Non-accrual loans and leases may be restored to accrual status when all delinquent principal and interest has been paid currently for six consecutive months or the loan or lease is considered secured and in the process of collection. The Corporation generally applies payments received on non-accruing loans and leases to principal until such time as the principal is paid off, after which time any payments received are recognized as interest income. If the Corporation believes that all amounts outstanding on a non-accrual loan or lease will ultimately be collected, payments received subsequent to its classification as a non-accrual loan or lease are allocated between interest income and principal. A loan or lease that is 90 days delinquent may continue to accrue interest if the loan or lease is both adequately secured and is in the process of collection. Past due status is determined based on contractual due dates for loan payments. An adequately secured loan or lease is one that has collateral with a supported fair value that is sufficient to discharge the debt, and/or has an enforceable guarantee from a financially responsible party. A loan or lease is considered to be in the process of collection if collection is proceeding through legal action or through other activities that are reasonably expected to result in repayment of the debt or restoration to current status in the near future. Loans and leases deemed to be a loss are written off through a charge against the allowance for loan or lease losses. Closed-end consumer loans are generally charged off when they become 120 days past due ( 180 days for open-end consumer loans) if they are not adequately secured by real estate. All other loans and leases are evaluated for possible charge-off when it is probable that the balance will not be collected, based on the ability of the borrower to pay and the value of the underlying collateral. Principal recoveries of loans or leases previously charged off are recorded as increases to the allowance for loan or lease losses. Loan Origination Fees and Costs: Loan origination fees and the related direct origination costs are deferred and amortized over the life of the loan as an adjustment to interest income using the effective yield method. For mortgage loans sold, net loan origination fees and costs are included in the gain or loss on sale of the related loan, as components of mortgage banking. Troubled Debt Restructurings ("TDRs"): Loans whose terms are modified are classified as TDRs if it is determined that those borrowers are experiencing financial difficulty and the Corporation grants the borrowers concessions. Concessions, whether negotiated or imposed by bankruptcy, granted under a TDR typically involve a temporary deferral of scheduled loan payments, an extension of a loan’s stated maturity date or a reduction in the interest rate. Non-accrual TDRs can be restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after modification. Allowance for Credit Losses: The allowance for credit losses consists of the allowance for loan and lease losses and the reserve for unfunded lending commitments. The allowance for loan and lease losses represents management’s estimate of incurred losses in the loan and lease portfolio as of the balance sheet date and is recorded as a reduction to loans and leases. The reserve for unfunded lending commitments represents management’s estimate of incurred losses in its unfunded loan commitments and other off-balance sheet credit exposures, such as letters of credit, and is recorded in other liabilities on the consolidated balance sheets. The allowance for credit losses is increased by charges to expense, through the provision for credit losses, and decreased by charge-offs, net of recoveries. Management believes that the allowance for loan and lease losses and the reserve for unfunded lending commitments are adequate as of the balance sheet date; however, future changes to the allowance or reserve may be necessary based on changes in any of the factors discussed in the following paragraphs. Maintaining an appropriate allowance for credit losses is dependent upon various factors, including the ability to identify potential problem loans and leases in a timely manner. For commercial loans, commercial mortgages and construction loans to commercial borrowers, an internal risk rating process is used. The Corporation believes that internal risk ratings are the most relevant credit quality indicator for these types of loans. The migration of loans through the various internal risk rating categories is a significant component of the allowance for credit loss methodology for these loans, which bases the probability of default on this migration. Assigning risk ratings involves judgment. The Corporation's loan review officers provide a separate assessment of risk rating accuracy. Risk ratings may be changed based on the ongoing monitoring procedures performed by loan officers or credit administration staff, or if specific loan review assessments identify a deterioration or an improvement in the loan. The following is a summary of the Corporation's internal risk rating categories: • Pass : These loans do not currently pose undue credit risk and can range from the highest to average quality, depending on the degree of potential risk. • Special Mention : These loans have a heightened credit risk, but not to the point of justifying a classification of substandard. Loans in this category are currently acceptable, but are nevertheless potentially weak. • Substandard or Lower : These loans are inadequately protected by current sound worth and paying capacity of the borrower. There exists a well-defined weakness or weaknesses that jeopardize the normal repayment of the debt. The Corporation does not assign internal risk ratings for smaller balance, homogeneous loans and leases, such as home equity, residential mortgage, consumer, lease receivables and construction loans to individuals secured by residential real estate. For these loans and leases, the most relevant credit quality indicator is delinquency status. The migration of loans and leases through the various delinquency status categories is a significant component of the allowance for credit loss methodology for these loans and leases, which bases the probability of default on this migration. The Corporation’s allowance for loan and lease losses includes: 1) specific allowances allocated to loans and leases evaluated for impairment under the Financial Accounting Standards Board's Accounting Standards Codification ("ASC") Section 310-10-35; and 2) allowances calculated for pools of loans evaluated for impairment under ASC Subtopic 450-20. A loan or lease is considered to be impaired if it is probable that all amounts will not be collected according to the contractual terms of the loan or lease agreement. Impaired loans and leases consist of all loans and leases on non-accrual status and accruing TDRs. An allowance for loan and lease losses is established for an impaired loan or lease if its carrying value exceeds its estimated fair value. Impaired loans and leases to borrowers with total outstanding commitments greater than or equal to $1.0 million are evaluated individually for impairment. Impaired loans and leases to borrowers with total outstanding commitments less than $1.0 million are pooled and evaluated for impairment collectively. All loans and leases evaluated for impairment under ASC Section 310-10-35 are measured for losses on a quarterly basis. As of December 31, 2019 and 2018 , substantially all of the Corporation’s impaired loans and leases to borrowers with total outstanding loan or lease balances greater than or equal to $1.0 million were measured based on the estimated fair value of each loan or lease’s collateral. Collateral could be in the form of real estate, in the case of impaired commercial mortgages and construction loans, or business assets, such as accounts receivable or inventory, in the case of commercial and industrial loans. Commercial and industrial loans may also be secured by real property. For loans and leases secured by real estate, estimated fair values are determined primarily through appraisals performed by state certified third-party appraisers, discounted to arrive at expected net sale proceeds. For collateral dependent loans, estimated real estate fair values are also net of estimated selling costs. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated appraisal of the real estate is necessary. This decision is based on various considerations, including: the age of the most recent appraisal; the loan-to-value ratio based on the original appraisal; the condition of the property; the Corporation’s experience and knowledge of the real estate market; the purpose of the loan or lease; market factors; payment status; the strength of any guarantors; and the existence and age of other indications of value such as broker price opinions, among others. The Corporation generally obtains updated appraisals performed by state certified third-party appraisers for impaired loans and leases secured predominantly by real estate every 12 months. As of December 31, 2019 and 2018 , approximately 93% and 89% , respectively, of impaired loans or leases with principal balances greater than or equal to $1.0 million , whose primary collateral is real estate, were measured at estimated fair value using appraisals performed by state certified third-party appraisers that had been updated within the preceding 12 months. When updated appraisals are not obtained for loans and leases secured by real estate and evaluated for impairment under ASC Section 310-10-35, fair values are estimated based on the original appraisal values, as long as the original appraisal indicated an acceptable loan-to-value position and, in the opinion of the Corporation's internal credit administration staff, there has not been a significant deterioration in the collateral value since the original appraisal was performed. For impaired loans and leases with principal balances greater than or equal to $1.0 million secured by non-real estate collateral, such as accounts receivable or inventory, estimated fair values are determined based on borrower financial statements, inventory listings, accounts receivable agings or borrowing base certificates. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Liquidation or collection discounts are applied to these assets based upon existing loan evaluation policies. All loans and leases not evaluated for impairment under ASC Section 310-10-35 are evaluated for impairment under ASC Subtopic 450-20, using a pooled loss evaluation approach. Loans and leases are segmented into pools with similar characteristics and a consistently developed loss factor is then applied to all loans in these pools. Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on class segments. For commercial loans, class segments include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments are based on collateral types and include direct consumer installment loans, home equity loans and indirect automobile loans. The Corporation segments its loan and lease portfolio by general loan and lease type, or "portfolio segments," as presented in the table under the heading, "Loans and leases, net of unearned income," within Note 4, "Loans and Leases and Allowance for Credit Losses." Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on "class segments," which are largely based on the type of collateral underlying each loan and lease. For commercial loans, class segments include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments are based on collateral types and include direct consumer installment loans and indirect automobile loans. The Corporation calculates allowance for loan and lease loss allocation needs for loans evaluated under ASC Subtopic 450-20 through the following procedures: • The loans and leases are segmented into pools with similar characteristics, as noted above. Commercial loans, commercial mortgages and construction loans to commercial borrowers are further segmented into separate pools based on internally assigned risk ratings. Residential mortgages, home equity loans, consumer loans, and lease receivables are further segmented into separate pools based on delinquency status; • A loss rate is calculated for each pool through an analysis of historical losses as loans and leases migrate through the various risk rating or delinquency categories. Estimated loss rates are based on a probability of default and a loss rate forecast; • The loss rate is adjusted to consider qualitative factors, such as economic conditions and trends; and • The resulting adjusted loss rate is applied to the balance of the loans and leases in the pool to arrive at the allowance allocation for the pool. The allocation of the allowance for credit losses is reviewed to evaluate its appropriateness in relation to the overall risk profile of the loan and lease portfolio. The Corporation considers risk factors such as: local and national economic conditions; trends in delinquencies and non-accrual loans and leases; the diversity of borrower industry types; and the composition of the portfolio by loan and lease type. Premises and Equipment: Premises and equipment are stated at cost, less accumulated depreciation and amortization. The provision for depreciation and amortization is generally computed using the straight-line method over the estimated useful lives of the related assets, which are a maximum of 50 years for buildings and improvements, 8 years for furniture and 5 years for equipment. Leasehold improvements are amortized over the shorter of the useful life or the non-cancelable lease term. See Note 5, "Premises and Equipment" for additional information. Other Real Estate Owned ("OREO"): Assets acquired in settlement of mortgage loan indebtedness are recorded as OREO and are included in other assets on the consolidated balance sheets, initially at the lower of the estimated fair value of the asset, less estimated selling costs, or the carrying amount of the loan. Costs to maintain the assets and subsequent gains and losses on sales are included in other non-interest expense on the consolidated statements of income. Mortgage Servicing Rights ("MSRs"): The estimated fair value of MSRs related to residential mortgage loans sold and serviced by the Corporation is recorded as an asset upon the sale of such loans. MSRs are amortized as a reduction to servicing income over the estimated lives of the underlying loans. MSRs are stratified and evaluated for impairment by comparing each stratum's carrying amount to its estimated fair value. Fair values are determined through a discounted cash flows valuation completed by a third-party valuation expert. Significant inputs to the valuation include expected net servicing income, the discount rate and the expected lives of the underlying loans. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. To the extent the amortized cost of the MSRs exceeds their estimated fair value, a valuation allowance is established through a charge against servicing income, included as a component of mortgage banking income on the consolidated statements of income. If subsequent valuations indicate that impairment no longer exists, the valuation allowance is reduced through an increase to servicing income. See Note 7, "Mortgage Servicing Rights" for additional information. Derivative Financial Instruments: The Corporation manages its exposure to certain interest rate and foreign currency risks through the use of derivatives. None of the Corporation's outstanding derivative contracts are designated as hedges and none are entered into for speculative purposes. Derivative instruments are carried at fair value, with changes in fair value recognized in earnings as components of non-interest income or non-interest expense on the consolidated statements of income. Derivative contracts create counterparty credit risk with both the Corporation's customers and with institutional derivative counterparties. The Corporation manages counterparty credit risk through its credit approval processes, monitoring procedures and obtaining adequate collateral, when the Corporation determines it is appropriate to do so and in accordance with counterparty contracts. Mortgage Banking Derivatives In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Interest Rate Swaps The Corporation enters into interest rate swaps with certain qualifying commercial loan customers to meet their interest rate risk management needs. The Corporation simultaneously enters into interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of these interest rate swaps is that the customer pays a fixed rate of interest and the Corporation receives a floating rate. The Bank exceeds $10 billion in total assets and is required to clear all eligible interest rate swap contracts with a central counterparty. As a result, the Bank is subject to the regulations of the Commodity Futures Trading Commission. Foreign Exchange Contracts The Corporation enters into foreign exchange contracts to accommodate the needs of its customers. Foreign exchange contracts are commitments to buy or sell foreign currency on a specific date at a contractual price. The Corporation limits its foreign exchange exposure with customers by entering into contracts with institutional counterparties to mitigate its foreign exchange risk. The Corporation also holds certain amounts of foreign currency with international correspondent banks ("Foreign Currency Nostro Accounts"). The Corporation limits the total overnight net foreign currency open positions, which is defined as an aggregate of all outstanding contracts and Foreign Currency Nostro Account balances, to $500,000 . See "Note 10 - Derivative Financial Instruments" for additional information. Balance Sheet Offsetting: Although certain financial assets and liabilities may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements, the Corporation elects to not offset such qualifying assets and liabilities. The Corporation is a party to interest rate swap transactions with financial institution counterparties and customers. Under these agreements, the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. Cash collateral is posted by the party with a net liability position in accordance with contract thresholds and can be used to settle the fair value of the interest rate swap agreements in the event of default. A daily settlement occurs through a clearing agent for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through a daily clearing agent. As a result, the total fair values of interest rate swap derivative assets and derivative liabilities recognized on the consolidated balance sheets are not equal and offsetting. The Corporation is also a party to foreign currency exchange contracts with financial institution counterparties, under which the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. As with interest rate swap contracts, cash collateral is posted by the party with a net liability position in accordance with contract thresholds and can be used to settle the fair value of the foreign currency exchange contracts in the event of default. The Corporation also enters into agreements with customers in which it sells securities subject to an obligation to repurchase the same or similar securities, referred to as repurchase agreements. Under these agreements, the Corporation may transfer legal control over the assets but still maintain effective control through agreements that both entitle and obligate the Corporation to repurchase the assets. Therefore, repurchase agreements are reported as secured borrowings, classified in short-term borrowings on the consolidated balance sheets, while the securities underlying the repurchase agreements remain classified with investment securities on the consolidated balance sheets. The Corporation has no intention of setting off these amounts, therefore, these repurchase agreements are not eligible for offset. For additional details on balance sheet offsetting, see "Note 10 - Derivative Financial Instruments." Income Taxes: The Corporation utilizes the asset and liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. In assessing the realizability of deferred tax assets ("DTAs"), management considers whether it is more likely than not that some portion or all of the DTAs will not be realized. The ultimate realization of DTAs is dependent upon the generation of future taxable income and tax planning strategies which will create taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, the amount of taxes paid in available carryback years, projected future taxable income, and, if necessary, tax planning strategies in making this assessment. A valuation allowance is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized. ASC Topic 740, "Income Taxes" creates a single model to address uncertainty in tax positions, and clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in an enterprise's financial statements. It also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The liability for unrecognized tax benefits is included in other liabilities within the consolidated balance sheets. Effective January 1, 2018, the Corporation adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This standards update permits a reclassification from accumulated other comprehensive income ("AOCI") to retained earnings of the stranded tax

The amortized cost of the securities transferred was $158.9 million and the estimated fair value was $168.5 million . The Corporation has the positive intent and ability to hold the remainder of the held to maturity portfolio, consisting of residential mortgage-backed securities, to maturity. On August 1, 2018, the Corporation transferred debt securities with an amortized cost of $665.5 million and an estimated fair value of $ 641.7 million from the available for sale classification to the held to maturity classification. These securities consisted of residential mortgage-backed securities ( $505.5 million amortized cost and $485.3 million estimated fair value) and state and municipal securities ( $160.0 million amortized cost and $156.4 million estimated fair value) and were transferred as the Corporation had the positive intent and ability to hold these securities to maturity. The transfer of debt securities into the held to maturity category from the available for sale category was recorded at fair value on the date of transfer. The net unrealized gains or losses at the transfer date are included in AOCI and are being amortized over the remaining lives of the securities. This amortization is expected to offset the amortization of the related premium or discount created by the investment securities transfer into the held to maturity classification, with no expected impact on future net income. Securities carried at $462.6 million at December 31, 2019 and $973.4 million at December 31, 2018 , were pledged as collateral to secure public and trust deposits and customer repurchase agreements. The amortized cost and estimated fair values of debt securities as of December 31, 2019 , by contractual maturity, are shown in the following table.

Because the decline in fair value of these securities is attributable to changes in interest rates and not credit quality, and because the Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, the Corporation did not consider these investments to be other-than-temporarily impaired as of December 31, 2019 . As of December 31, 2019 , all auction rate certificates ("ARCs") were rated above investment grade. All of the loans underlying the ARCs have principal payments which are guaranteed by the federal government. All of the loans were current and making scheduled payments and, based on management’s evaluations, were not subject to any OTTI charges as of December 31, 2019 . The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell these securities prior to a recovery of their fair value to amortized cost, which may be at maturity. Based on management’s evaluations, no corporate debt securities were subject to any OTTI charges as of December 31, 2019 . The Corporation does not have the intent to sell and does not believe it will more likely than not be required to sell any of these securities prior to a recovery of their fair value to amortized cost, which may be at maturity.

Goodwill and Intangible Assets	NOTE 6 – GOODWILL AND INTANGIBLE ASSETS Goodwill totaled $532.7 million and $530.6 million as of December 31, 2019 and 2018 , respectively. A non-amortizing trade name intangible asset that totaled $1.0 million as of December 31, 2018 was written off during 2019 as a result of the consolidation of the Corporation's banking subsidiaries into Fulton Bank. The increase in total goodwill of $2.1 million was the result of acquisitions of the assets of two wealth management businesses in 2019. The Corporation’s reporting units passed the 2019 goodwill impairment test, resulting in no goodwill impairment charges in 2019 . The estimated fair values of the Corporation’s reporting units are subject to uncertainty, including future changes in fair values of banks in general and future operating results of reporting units, which could differ significantly from the assumptions used in the current valuation of reporting units.

The total portfolio of mortgage loans serviced by the Corporation for unrelated third parties was $4.9 billion and $4.8 billion as of December 31, 2019 and 2018 , respectively. Actual and expected prepayments of the underlying mortgage loans can impact the value of MSRs. The Corporation accounts for MSRs at the lower of amortized cost or fair value. The fair value of MSRs is estimated by discounting the estimated cash flows from servicing income, net of expense, over the expected life of the underlying loans at a discount rate commensurate with the risk associated with these assets. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. The fair values of MSRs were $45.2 million and $50.2 million as of December 31, 2019 and 2018, respectively. Total MSR amortization expense, recognized as a reduction to mortgage banking income in the consolidated statements of income, was $6.9 million and $5.8 million in 2019 and 2018, respectively. Estimated MSR amortization expense for the next five years, based on balances as of December 31, 2019 and the estimated remaining lives of the underlying loans, follows (in thousands): Year 2020 $ 6,591 2021 6,144 2022 5,648 2023 5,101 2024 4,499

Regulatory Matters [Abstract]
Regulatory Matters	NOTE 11 – REGULATORY MATTERS Regulatory Capital Requirements The Corporation and the Bank are subject to regulatory capital requirements administered by banking regulators. Failure to meet minimum capital requirements can trigger certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. U.S. Basel III Capital Rules In July 2013, the FRB approved final rules (the "U.S. Basel III Capital Rules") establishing a new comprehensive capital framework for U.S. banking organizations and implementing the Basel Committee on Banking Supervision's December 2010 framework for strengthening international capital standards. The U.S. Basel III Capital Rules substantially revised the risk-based capital requirements applicable to bank holding companies and depository institutions. The minimum regulatory capital requirements established by the U.S. Basel III Capital Rules became effective on January 1, 2015, and became fully phased in on January 1, 2019. The U.S. Basel III Capital Rules require the Corporation and the Bank to: • Meet a minimum Common Equity Tier 1 capital ratio of 4.50% of risk-weighted assets and a minimum Tier 1 capital of 6.00% of risk-weighted assets; • Meet a minimum Total capital ratio of 8.00% of risk-weighted assets and a minimum Tier 1 leverage capital ratio of 4.00% of average assets; • Maintain a "capital conservation buffer" of 2.50% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus payments; and • Comply with a revised definition of capital to improve the ability of regulatory capital instruments to absorb losses. Certain non-qualifying capital instruments, including cumulative preferred stock and TruPS, are excluded as a component of Tier 1 capital for institutions of the Corporation's size. The U.S. Basel III Capital Rules use a standardized approach for risk weightings that expand the risk-weightings for assets and off-balance sheet exposures from the previous 0%, 20%, 50% and 100% categories to a much larger and more risk-sensitive number of categories, depending on the nature of the assets and off-balance sheet exposures, resulting in higher risk weights for a variety of asset categories. Effective January 1, 2019, the Corporation and the Bank were also required to maintain a "capital conservation buffer" of 2.50% above the minimum risk-based capital requirements. The rules provide that the failure to maintain the "capital conservation buffer" results in restrictions on capital distributions and discretionary cash bonus payments to executive officers. As a result, under the U.S. Basel III Capital Rules, if the Bank fails to maintain the required minimum capital conservation buffer, the Corporation will be subject to limits, and possibly prohibitions, on its ability to obtain capital distributions from such subsidiaries. If the Corporation does not receive sufficient cash dividends from the Bank, it may not have sufficient funds to pay dividends on its common stock, service its debt obligations or repurchase its common stock. As of December 31, 2019 , the Corporation's capital levels met the fully phased-in minimum capital requirements, including the new capital conservation buffers, as prescribed in the U.S. Basel III Capital Rules. As of December 31, 2019 , the Bank was well capitalized under the regulatory framework for prompt corrective action based on their capital ratio calculation. As of December 31, 2018, each of the Corporation’s subsidiary banks was well capitalized under the regulatory framework for prompt corrective action based on their capital ratio calculations. To be categorized as well capitalized, these banks were required to maintain minimum total risk-based, Tier I risk-based, Common Equity Tier I risk-based and Tier I leverage ratios as set forth in the following table. There are no conditions or events since December 31, 2019 that management believes have changed the institutions’ categories.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and/or capital gain income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, such as those that may be implemented to generate capital gains, in making this assessment. The valuation allowance relates to state deferred tax assets and net operating loss carryforwards for which realizability is uncertain. As of December 31, 2019 and 2018 , the Corporation had state net operating loss carryforwards of approximately $392.0 million and $347.3 million , respectively, which are available to offset future state taxable income, and expire at various dates through 2038 . Based on the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Corporation will realize the benefits of its deferred tax assets, net of the valuation allowance, as of December 31, 2019 . As of December 31, 2019 , the Corporation had tax credit carryforwards related to TCIs of approximately $43 million . The corporation recorded a deferred tax asset of $43.1 million , reflecting the benefit of these tax credit carryforwards. Such deferred tax asset will begin to expire in 2038 if not yet utilized. Uncertain Tax Positions The following table summarizes the changes in unrecognized tax benefits for the years ended December 31 : 2019 2018 2017 (in thousands) Balance at beginning of year $ 2,726 $ 2,550 $ 2,438 Current period tax positions 292 593 523 Lapse of statute of limitations (501 ) (417 ) (411 ) Balance at end of year $ 2,517 $ 2,726 $ 2,550 Virtually all of the Corporation’s unrecognized tax benefits are for positions that are taken on an annual basis on state tax returns. Increases to unrecognized tax benefits will occur as a result of accruing for the nonrecognition of the position for the current year. Decreases will occur as a result of the lapsing of the statute of limitations for the oldest outstanding year which includes the position. These offsetting increases and decreases are likely to continue in the future, including over the next twelve months. While the net effect on total unrecognized tax benefits during this period cannot be reasonably estimated, approximately $460,000 is expected to reverse in 2020 due to lapsing of the statute of limitations. Decreases can also occur throughout the settlement of positions with taxing authorities. As of December 31, 2019 , if recognized, all of the Corporation’s unrecognized tax benefits would impact the effective tax rate. Not included in the table above is $549,000 of federal income tax benefit on unrecognized state tax benefits which, if recognized, would also impact the effective tax rate. Interest accrued related to unrecognized tax benefits is recorded as a component of income tax expense. Penalties, if incurred, would also be recognized in income tax expense. The Corporation recognized approximately $22,000 and $59,000 in 2019 and 2018 , respectively, for interest and penalties in income tax expense related to unrecognized tax positions. As of December 31, 2019 and 2018 , total accrued interest and penalties related to unrecognized tax positions were approximately $697,000 and $675,000 , respectively. The Corporation files income tax returns in the federal and various state jurisdictions. In most cases, unrecognized tax benefits are related to tax years that remain subject to examination by the relevant taxing authorities. With few exceptions, the Corporation is no longer subject to federal, state and local examinations by tax authorities for years before 2016 . Tax Credit Investments ("TCIs") The TCIs are included in other assets, with any unfunded equity commitments recorded in other liabilities on the consolidated balance sheets. Certain TCIs qualify for the proportional amortization method and are amortized over the period the Corporation expects to receive the tax credits, with the expense included within income taxes on the consolidated statements of income.

Net Income Per Share	NOTE 13 – NET INCOME PER SHARE Basic net income per common share is calculated as net income divided by the weighted average number of shares outstanding. Diluted net income per share is calculated as net income divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. The Corporation’s common stock equivalents consist of outstanding stock options, restricted stock, RSUs and PSUs. PSUs are required to be included in weighted average diluted shares outstanding if performance measures, as defined in each PSU award agreement, are met as of the end of the period. A reconciliation of weighted average common shares outstanding used to calculate basic and diluted net income per share follows: 2019 2018 2017 (in thousands) Weighted average common shares outstanding (basic) 166,902 175,395 174,721 Impact of common stock equivalents 890 1,148 1,211 Weighted average common shares outstanding (diluted) 167,792 176,543 175,932

Share-based Payment Arrangement [Abstract]
Stock-based compensation plans	NOTE 15 – STOCK-BASED COMPENSATION PLANS The following table presents compensation expense and related tax benefits for all equity awards recognized in the consolidated statements of income: 2019 2018 2017 (in thousands) Compensation expense $ 7,413 $ 7,965 $ 5,209 Tax benefit (1,610 ) (2,625 ) (3,994 ) Total stock-based compensation, net of tax $ 5,803 $ 5,340 $ 1,215 The tax benefits as a percentage of compensation expense, as shown in the preceding table, were 21.7% , 33.0% and 76.7% in 2019 , 2018 and 2017 , respectively. These percentages differ from the Corporation’s statutory tax rates of 21% for 2019 and 2018 and 35% for 2017 ("Tax Rates"). Tax benefits are only recognized over the vesting period for awards that ordinarily will generate a tax deduction when exercised, in the case of non-qualified stock options, or upon vesting, in the case of restricted stock, RSUs and PSUs. Tax benefits in excess of the Tax Rates resulted from incentive stock option exercises that triggered a tax deduction when they were exercised, and excess tax benefits realized on vesting RSUs and PSUs during the period. The following table presents compensation expense and related tax benefits for restricted stock awards, RSUs and PSUs recognized in the consolidated statements of income, and included as a component of total stock-based compensation in the preceding table: 2019 2018 2017 (in thousands) Compensation expense $ 6,621 $ 7,124 $ 4,922 Tax benefit (1,509 ) (1,585 ) (1,559 ) Stock-based compensation, net of tax $ 5,112 $ 5,539 $ 3,363 The following table provides information about stock option activity for the year ended December 31, 2019 : Stock Weighted Weighted Aggregate Outstanding and exercisable as of December 31, 2018 658,768 $ 10.75 Exercised (150,296 ) 9.73 Forfeited (4,128 ) 11.31 Expired (4,084 ) 5.27 Outstanding and exercisable as of December 31, 2019 500,260 $ 11.12 3.1 years $ 3.2 The following table provides information about nonvested restricted stock, RSUs and PSUs granted under the Employee Equity Plan and Directors' Plan for the year ended December 31, 2019 : Restricted Stock/RSUs/PSUs (1) Shares Weighted Nonvested as of December 31, 2018 1,368,493 $ 15.49 Granted 454,951 15.51 Vested (407,872 ) 12.38 Forfeited (43,236 ) 16.61 Nonvested as of December 31, 2019 1,372,336 $ 16.39 (1) There were no nonvested stock options at December 31, 2019 or 2018. As of December 31, 2019 , there was $10.1 million of total unrecognized compensation cost (pre-tax) related to restricted stock, RSUs and PSUs that will be recognized as compensation expense over a weighted average period of two years. As of December 31, 2019 , the Employee Equity Plan had 10.1 million shares reserved for future grants through 2023 , and the Directors’ Plan had 260,000 shares reserved for future grants through 2021 . The following table presents information about stock options exercised: 2019 2018 2017 (dollars in thousands) Number of options exercised 150,296 214,845 411,292 Total intrinsic value of options exercised $ 1,028 $ 1,616 $ 2,955 Cash received from options exercised $ 1,446 $ 2,210 $ 4,644 Tax benefit from options exercised $ 188 $ 291 $ 989 Upon exercise, the Corporation issues shares from its authorized, but unissued, common stock to satisfy the options. The fair value of certain PSUs with market-based performance conditions granted under the Employee Equity Plan was estimated on the grant date using the Monte Carlo valuation methodology performed by a third-party valuation expert. This valuation is dependent upon certain assumptions, as summarized in the following table: 2019 2018 2017 Risk-free interest rate 2.27 % 2.63 % 1.43 % Volatility of Corporation’s stock 23.00 % 23.50 % 22.45 % Expected life of PSUs 3 Years 3 Years 3 Years The expected life of the PSUs with fair values measured using the Monte Carlo valuation methodology was based on the defined performance period of three years . Volatility of the Corporation’s stock was based on historical volatility for the period commensurate with the expected life of the PSUs. The risk-free interest rate is the zero-coupon U.S. Treasury rate commensurate with the expected life of the PSUs on the date of the grant. Based on the assumptions above, the Corporation calculated an estimated fair value per PSU with market-based performance conditions granted in 2019, 2018 and 2017 of $16.83 , $12.92 and $17.25 , respectively. Under the ESPP, eligible employees can purchase stock of the Corporation at 85% of the fair market value of the stock on the date of purchase. The ESPP is considered to be a compensatory plan and, as such, compensation expense is recognized for the 15% discount on shares purchased. The following table summarizes activity under the ESPP: 2019 2018 2017 ESPP shares purchased 136,576 110,200 98,000 Average purchase price per share (85% of market value) $ 14.03 $ 14.74 $ 15.28 Compensation expense recognized (in thousands) $ 338 $ 287 $ 261

Employee and employer contributions under these features are 100% vested. Contributions to the Defined Benefit Pension Plan ("Pension Plan") are actuarially determined and funded annually, if necessary. The Corporation recognizes the funded status of its Pension Plan on the consolidated balance sheets and recognizes the changes in that funded status through other comprehensive income. The Pension Plan has been curtailed, with no additional benefits accruing to participants. Pension Plan The net periodic pension cost for the Pension Plan, as determined by consulting actuaries, consisted of the following components for the years ended December 31 : 2019 2018 2017 (in thousands) Interest cost $ 3,257 $ 3,053 $ 3,320 Expected return on assets (2,754 ) (2,047 ) (1,804 ) Net amortization and deferral 1,981 2,429 2,652 Net periodic pension cost $ 2,484 $ 3,435 $ 4,168 The following table summarizes the changes in the projected benefit obligation and fair value of plan assets for the plan years ended December 31 : 2019 2018 (in thousands) Projected benefit obligation at beginning of year $ 79,426 $ 89,482 Interest cost 3,257 3,053 Benefit payments (4,114 ) (5,796 ) Change in assumptions 8,259 (8,051 ) Experience (loss) gain (624 ) 738 Projected benefit obligation at end of year $ 86,204 $ 79,426 Fair value of plan assets at beginning of year $ 57,825 $ 54,061 Employer contributions (1) 20,755 13,042 Actual return on plan assets 9,210 (3,482 ) Benefit payments (4,114 ) (5,796 ) Fair value of plan assets at end of year $ 83,676 $ 57,825 (1) The Corporation funds at least the minimum amount required by federal law and regulations.

The following rates were used to calculate net periodic pension cost and the present value of benefit obligations as of December 31 : 2019 2018 2017 Discount rate-projected benefit obligation 3.25 % 4.25 % 3.50 % Expected long-term rate of return on plan assets 5.00 % 5.00 % 5.00 % The discount rates used were determined using the Citigroup Average Life discount rate table, as adjusted based on the Pension Plan's expected benefit payments and rounded to the nearest 0.25% . The 5.00% long-term rate of return on plan assets used to calculate the net periodic pension cost was based on historical returns, adjusted for expectations of long-term asset returns based on the December 31, 2019 weighted average asset allocations. The expected long-term return is considered to be appropriate based on the asset mix and the historical returns realized.

The goal of the investment allocation strategy is to match certain benefit obligations with maturities of fixed income securities. Alternative investments may include managed futures, commodities, real estate investment trusts, master limited partnerships, and long-short strategies with traditional stocks and bonds. All alternative investments are in the form of mutual funds, not individual contracts, to enable daily liquidity. The fair values for all assets held by the Pension Plan, excluding equity common trust funds, are based on quoted prices for identical instruments and would be categorized as Level 1 assets under the fair value hierarchy. Equity common trust funds would be categorized as Level 2 assets under the fair value hierarchy.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 18 – COMMITMENTS AND CONTINGENCIES Commitments The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. 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. Since a portion of the commitments is expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral, if any, obtained upon extension of credit is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property, equipment and income producing commercial properties. Standby letters of credit are conditional commitments issued to guarantee the financial or performance obligation of a customer to a third party. Commercial letters of credit are conditional commitments issued to facilitate foreign and domestic trade transactions for customers. The credit risk involved in issuing letters of credit is similar to that involved in extending loan facilities. These obligations are underwritten consistently with commercial lending standards. The maximum exposure to loss for standby and commercial letters of credit is equal to the contractual (or notional) amount of the instruments. The Corporation records a reserve for unfunded commitments, included in other liabilities on the consolidated balance sheets, which represents management’s estimate of losses inherent in commitments to extend credit and letters of credit. See "Note 4 - Loans and Leases and Allowance for Credit Losses," for additional information. The following table presents the Corporation’s commitments to extend credit and letters of credit: 2019 2018 (in thousands) Commercial, industrial, financial and agricultural $ 3,997,401 $ 3,642,545 Real estate - home equity 1,523,494 1,475,066 Real estate - commercial mortgage and real estate - construction 1,168,624 1,188,972 Total commitments to extend credit $ 6,689,519 $ 6,306,583 Standby letters of credit $ 303,020 $ 309,352 Commercial letters of credit 50,432 48,682 Total letters of credit $ 353,452 $ 358,034 Residential Lending The Corporation originates and sells residential mortgages to secondary market investors. The Corporation provides customary representations and warranties to secondary market investors that specify, among other things, that the loans have been underwritten to the standards of the secondary market investor. The Corporation may be required to repurchase specific loans, or reimburse the investor for a credit loss incurred on a sold loan if it is determined that the representations and warranties have not been met. Under some agreements with secondary market investors, the Corporation may have additional credit exposure beyond customary representations and warranties, based on the specific terms of those agreements. The Corporation maintains a reserve for estimated credit losses related to loans sold to investors. As of December 31, 2019 and 2018, the total reserve for losses on residential mortgage loans sold was $3.2 million and $2.1 million, respectively, including reserves for both representation and warranty and credit loss exposures. Legal Proceedings The Corporation is involved in various pending and threatened claims and other legal proceedings in the ordinary course of its business activities. The Corporation evaluates the possible impact of these matters, taking into consideration the most recent information available. A loss reserve is established for those matters for which the Corporation believes a loss is both probable and reasonably estimable. Once established, the reserve is adjusted as appropriate to reflect any subsequent developments. Actual losses with respect to any such matter may be more or less than the amount estimated by the Corporation. For matters where a loss is not probable, or the amount of the loss cannot be reasonably estimated by the Corporation, no loss reserve is established. In addition, from time to time, the Corporation is involved in investigations or other forms of regulatory or governmental inquiry covering a range of possible issues and, in some cases, these may be part of similar reviews of the specified activities of other companies. These inquiries or investigations could lead to administrative, civil or criminal proceedings involving the Corporation, and could result in fines, penalties, restitution, other types of sanctions, or the need for the Corporation to undertake remedial actions, or to alter its business, financial or accounting practices. The Corporation’s practice is to cooperate fully with regulatory and governmental inquiries and investigations. As of the date of this report, the Corporation believes that any liabilities, individually or in the aggregate, which may result from the final outcomes of pending legal proceedings, or regulatory or governmental inquiries or investigations, will not have a material adverse effect on the financial condition of the Corporation. However, legal proceedings, inquiries and investigations are often unpredictable, and it is possible that the ultimate resolution of any such matters, if unfavorable, may be material to the Corporation’s results of operations in any future period, depending, in part, upon the size of the loss or liability imposed and the operating results for the period, and could have a material adverse effect on the Corporation’s business. In addition, regardless of the ultimate outcome of any such legal proceeding, inquiry or investigation, any such matter could cause the Corporation to incur additional expenses, which could be significant, and possibly material, to the Corporation’s results of operations in any future period. SEC Investigation The Corporation is responding to an investigation by the staff of the Division of Enforcement of the SEC regarding certain accounting determinations that could have impacted the Corporation’s reported earnings per share. The Corporation believes that its financial statements filed with the SEC in Forms 10-K and 10-Q present fairly, in all material respects, its financial condition, results of operations and cash flows as of or for the periods ending on their respective dates. The Corporation is cooperating fully with the SEC and at this time cannot predict when or how the investigation will be resolved. Kress v. Fulton Bank, N.A. On October 15, 2019, a former Fulton Bank teller supervisor, D. Kress filed a putative class action lawsuit on behalf of herself and other similarly situated non-exempt, hourly employees in the U.S. District Court for the District of New Jersey, D. Kress v. Fulton Bank, N.A. , Case No. 1:19-cv-18985. Fulton Bank accepted service of process on January 20, 2020. The lawsuit alleges that Fulton Bank did not record or otherwise account for the amount of time which non-exempt employees who are paid based on their time worked, spent conducting branch opening security procedures. The allegation is that, as a result, Fulton Bank did not properly compensate those employees for their regular and overtime wages. The lawsuit alleges that by doing so, Fulton violated: (i) the federal Fair Labor Standards Act and seeks back overtime wages for a period of three years, liquidated damages and attorney fees and costs; (ii) the New Jersey State Wage and Hour Law and seeks back overtime wages for a period of six years, treble damages and attorney fees and costs; and (iii) the New Jersey Wage Payment Law and seeks back wages for a period of six years, treble damages and attorney fees and costs. The lawsuit also asserts New Jersey common law claims seeking compensatory damages and interest.

Fair values as of December 31, 2019 and 2018 were measured as the price that secondary market investors were offering for loans with similar characteristics. See "Note 1 - Summary of Significant Accounting Policies" for details related to the Corporation’s election to measure assets and liabilities at fair value. • Available for sale investment securities – Included in this asset category are debt securities. Level 2 available for sale debt securities are valued by a third-party pricing service commonly used in the banking industry. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings and matrix pricing. Standard market inputs include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, including market research publications. For certain security types, additional inputs may be used, or some of the standard market inputs may not be applicable. Management tests the values provided by the pricing service by obtaining securities prices from an alternative third-party source and comparing the results. This test is performed for approximately 95% of the securities valued by the pricing service. Generally, differences by security in excess of 5% are researched to reconcile the difference. • State and municipal securities/Collateralized mortgage obligations/Residential mortgage-backed securities/Commercial mortgage-backed securities – These debt securities are classified as Level 2 investments. Fair values are determined by a third-party pricing service, as detailed above. • Corporate debt securities – This category consists of subordinated and senior debt issued by financial institutions ( $362.3 million at December 31, 2019 and $86.1 million at December 31, 2018 ), single-issuer trust preferred securities issued by financial institutions ( $11.2 million at December 31, 2019 and $18.6 million at December 31, 2018 ), pooled trust preferred securities issued by financial institutions ( $0 at December 31, 2019 and $875,000 at December 31, 2018 ) and other corporate debt issued by non-financial institutions ( $3.9 million at December 31, 2019 and December 31, 2018 ). Level 2 investments include subordinated debt and senior debt, other corporate debt issued by non-financial institutions and $8.8 million and $16.3 million of single-issuer trust preferred securities held at December 31, 2019 and 2018 , respectively. The fair values for these corporate debt securities are determined by a third-party pricing service, as detailed above. Level 3 investments include the Corporation's investments in pooled trust preferred securities ( $0 at December 31, 2019 and $875,000 at December 31, 2018 ) and certain single-issuer trust preferred securities ( $2.4 million at December 31, 2019 and December 31, 2018 ). The fair values of these securities were determined based on quotes provided by third-party brokers who determined fair values based predominantly on internal valuation models which were not indicative prices or binding offers. The Corporation’s third-party pricing service cannot derive fair values for these securities primarily due to inactive markets for similar investments. Level 3 values are tested by management primarily through trend analysis, by comparing current values to those reported at the end of the preceding calendar quarter, and determining if they are reasonable based on price and spread movements for this asset class. • Auction rate securities – Due to their illiquidity, ARCs are classified as Level 3 investments and are valued through the use of an expected cash flows model prepared by a third-party valuation expert. The assumptions used in preparing the expected cash flows model include estimates for coupon rates, time to maturity and market rates of return. The most significant unobservable input to the expected cash flows model is an assumed return to market liquidity sometime within the next five years. If the assumed return to market liquidity was lengthened beyond the next five years, this would result in a decrease in the fair value of these ARCs. The Corporation believes that the trusts underlying the ARCs will self-liquidate as student loans are repaid. Level 3 values are tested by management through the performance of a trend analysis of the market price and discount rate. Changes in the price and discount rates are compared to changes in market data, including bond ratings, parity ratios, balances and delinquency levels. • Investments held in Rabbi Trust - This category consists of mutual funds that are held in trust for employee deferred compensation plans that the Corporation has elected to measure at fair value. Shares of mutual funds are valued based on net asset value, which represents quoted market prices for the underlying shares held in the mutual funds, and as such, are classified as Level 1. • Derivative assets - Fair value of foreign currency exchange contracts classified as Level 1 assets ( $230,000 at December 31, 2019 and $392,000 at December 31, 2018 ). The mutual funds and foreign exchange prices used to measure these items at fair value are based on quoted prices for identical instruments in active markets. Level 2 assets, representing the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ( $1.2 million at December 31, 2019 and $1.2 million at December 31, 2018 ) and the fair value of interest rate swaps ( $144.2 million at December 31, 2019 and $61.4 million at December 31, 2018 ). The fair values of the interest rate locks, forward commitments and interest rate swaps represent the amounts that would be required to settle the derivative financial instruments at the balance sheet date. See "Note 10 - Derivative Financial Instruments," for additional information. • Deferred compensation liabilities – Fair value of amounts due to employees under deferred compensation plans, classified as Level 1 liabilities and are included in other liabilities on the consolidated balance sheets. The fair values of these liabilities are determined in the same manner as the related assets, as described under the heading "Investments held in Rabbi Trust" above. • Derivative liabilities - Level 1 liabilities, representing the fair value of foreign currency exchange contracts ( $199,000 at December 31, 2019 and $381,000 at December 31, 2018 ). The fair values of these liabilities are determined in the same manner as the related assets. Level 2 liabilities, representing the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors ( $424,000 at December 31, 2019 and $1.1 million at December 31, 2018 ) and the fair value of interest rate swaps ( $76.0 million at December 31, 2019 and $47.1 million at December 31, 2018 ). The fair values of these liabilities are determined in the same manner as the related assets, which are described under the heading "Derivative assets" above. The following table presents the changes in available for sale investment securities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the years ended December 31 : Pooled Trust Single-issuer Auction Rate Securities (in thousands) Balance as of December 31, 2017 $ 707 $ 3,050 $ 98,668 Realized adjustments to fair value — 71 — Unrealized adjustments to fair value (1) 168 221 4,326 Settlements - calls — (950 ) — Discount accretion (2) — 8 — Balance as of December 31, 2018 $ 875 $ 2,400 $ 102,994 Sales (770 ) — — Unrealized adjustments to fair value (1) (105 ) (4 ) (1,068 ) Discount accretion (2) — 4 — Balance as of December 31, 2019 $ — $ 2,400 $ 101,926 (1) Pooled trust preferred securities, single-issuer trust preferred securities and ARCs are classified as available for sale investment securities; as such, the unrealized adjustment to fair value was recorded as an unrealized holding gain (loss) and included as a component of "available for sale at estimated fair value" on the consolidated balance sheets. (2) Included as a component of "net interest income" on the consolidated statements of income. Certain financial instruments are not measured at fair value on an ongoing basis but are subject to fair value measurement in certain circumstances, such as upon their acquisition or when there is evidence of impairment. The following table presents Level 3 financial instruments measured at fair value on a nonrecurring basis: 2019 2018 (in thousands) Net loans and leases $ 144,807 $ 149,846 OREO 6,831 10,518 MSRs (1) 45,193 50,200 Total assets $ 196,831 $ 210,564 (1) Amounts shown are estimated fair value. MSRs are recorded on the Corporation's consolidated balance sheets at amortized cost. See "Note 5 - Mortgage Servicing Rights" for additional information. The valuation techniques used to measure fair value for the items in the table above are as follows: • Net loans and leases – This category consists of loans and leases that were individually evaluated for impairment and have been classified as Level 3 assets. The amount shown is the balance of impaired loans and leases, net of the related allowance for loan losses. See "Note 4 - Loans and Leases and Allowance for Credit Losses," for additional details. • OREO – This category consists of OREO classified as Level 3 assets, for which the fair values were based on estimated selling prices less estimated selling costs for similar assets in active markets. • MSRs - This category consists of MSRs, which were initially recorded at fair value upon the sale of residential mortgage loans to secondary market investors, and subsequently carried at the lower of amortized cost or fair value. MSRs are amortized as a reduction to servicing income over the estimated lives of the underlying loans. MSRs are stratified and evaluated for impairment by comparing each stratum's carrying amount to its estimated fair value. Fair values are determined at the end of each quarter through a discounted cash flows valuation performed by a third-party valuation expert. Significant inputs to the valuation included expected net servicing income, the discount rate and the expected life of the underlying loans. Expected life is based on the contractual terms of the loans, as adjusted for prepayment projections. The weighted average annual constant prepayment rate and the weighted average discount rate used in the December 31, 2019 valuation were 10.5% and 9.5% , respectively. Management tests the reasonableness of the significant inputs to the third-party valuation in comparison to market data. The following table details the book values and the estimated fair values of the Corporation’s financial instruments as of December 31, 2019 and 2018 . A general description of the methods and assumptions used to estimate such fair values is also provided. 2019 Estimated Fair Value Carrying Amount Level 1 Level 2 Level 3 Total FINANCIAL ASSETS (in thousands) Cash and cash equivalents $ 517,791 $ 517,791 $ — $ — $ 517,791 FRB and FHLB stock 97,422 — 97,422 — 97,422 Loans held for sale 37,828 — 37,828 — 37,828 Available for sale investment securities 2,497,537 — 2,393,211 104,326 2,497,537 Held to maturity investment securities 369,841 — 383,705 — 383,705 Net loans and leases 16,673,904 — — 16,485,122 16,485,122 Accrued interest receivable 60,898 60,898 — — 60,898 Other assets 431,565 234,176 145,365 52,024 431,565 FINANCIAL LIABILITIES Demand and savings deposits $ 14,327,453 $ 14,327,453 $ — $ — $ 14,327,453 Brokered deposits 264,531 223,982 40,549 — 264,531 Time deposits 2,801,930 — 2,828,988 — 2,828,988 Short-term borrowings 883,241 883,241 — — 883,241 Accrued interest payable 8,834 8,834 — — 8,834 FHLB advances and long-term debt 881,769 — 878,385 — 878,385 Other liabilities 221,542 142,508 76,447 2,587 221,542 2018 Estimated Fair Value Carrying Amount Level 1 Level 2 Level 3 Total (in thousands) FINANCIAL ASSETS Cash and cash equivalents $ 445,687 $ 445,687 $ — $ — $ 445,687 FRB and FHLB stock 79,283 — 79,283 — 79,283 Loans held for sale 27,099 — 27,099 — 27,099 Available for sale investment securities 2,080,294 — 1,974,025 106,269 2,080,294 Held to maturity investment securities 606,679 611,419 — — 611,419 Net loans and leases 16,005,263 — — 15,446,895 15,446,895 Accrued interest receivable 58,879 58,879 — — 58,879 Other assets 235,782 124,138 62,552 49,092 235,782 FINANCIAL LIABILITIES Demand and savings deposits $ 13,478,016 $ 13,478,016 $ — $ — $ 13,478,016 Brokered deposits 176,239 176,239 — — 176,239 Time deposits 2,721,904 — 2,712,296 — 2,712,296 Short-term borrowings 754,777 754,777 — — 754,777 Accrued interest payable 10,529 10,529 — — 10,529 FHLB advances and long-term debt 992,279 — 970,985 — 970,985 Other liabilities 218,061 161,003 48,185 8,873 218,061 Fair values of financial instruments are significantly affected by the assumptions used, principally the timing of future cash flows and discount rates. Because assumptions are inherently subjective in nature, the estimated fair values cannot be substantiated by comparison to independent market quotes and, in many cases, the estimated fair values could not necessarily be realized in an immediate sale or settlement of the instrument. The aggregate fair value amounts presented do not necessarily represent management’s estimate of the underlying value of the Corporation. For short-term financial instruments, defined as those with remaining maturities of 90 days or less, and excluding those recorded at fair value on the Corporation’s consolidated balance sheets, book value was considered to be a reasonable estimate of fair value. The following instruments are predominantly short-term: Assets Liabilities Cash and cash equivalents Demand and savings deposits Accrued interest receivable Short-term borrowings Accrued interest payable FRB and FHLB stock represent restricted investments and are carried at cost on the consolidated balance sheets, which is a reasonable estimate of fair value. As of December 31, 2019, fair values for loans and leases and time deposits were estimated by discounting future cash flows using the current rates, as adjusted for liquidity considerations, at which similar loans and leases would be made to borrowers and similar deposits would be issued to customers for the same remaining maturities. Fair values of loans and leases also include estimated credit losses that would be assumed in a market transaction, which represents estimated exit prices. Brokered deposits consists of demand and saving deposits, which are classified as level 1, and time deposits, which are classified as Level 2. The fair value of these deposits are determined in a manner consistent with the respective type of deposits discussed above.

Accounting Policies [Abstract]
Business and Basis of Financial Statement Presentation	Business: Fulton Financial Corporation ("Corporation" or "Parent Company") is a financial holding company which provides a full range of banking and financial services to businesses and consumers through its wholly owned banking subsidiary, Fulton Bank, N.A. ("Fulton Bank" or the "Bank"). In addition, the Parent Company owns the following non-bank subsidiaries: Fulton Financial Realty Company, Central Pennsylvania Financial Corp., FFC Management, Inc., FFC Penn Square, Inc. and Fulton Insurance Services Group, Inc. Collectively, the Parent Company and its subsidiaries are referred to as the Corporation. The Corporation’s primary sources of revenue are interest income on loans, investment securities and other interest-earning assets and fee income earned on its products and services. Its expenses consist of interest expense on deposits and borrowed funds, provision for credit losses, other operating expenses and income taxes. The Corporation’s primary competition is other financial services providers operating in its region. Competitors also include financial services providers located outside the Corporation’s geographic market as a result of the growth in electronic delivery channels. The Corporation is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by such regulatory authorities. The Corporation offers, through its banking subsidiary, a full range of retail and commercial banking services in Pennsylvania, Delaware, Maryland, New Jersey and Virginia. Industry diversity is the key to the economic well-being of these markets and the Corporation is not dependent upon any single customer or industry. In 2017, the Corporation had six banking subsidiaries. During 2018, the Corporation consolidated two of its wholly owned banking subsidiaries into its lead bank, Fulton Bank, and during 2019 , the remaining three wholly-owned banking subsidiaries were consolidated into Fulton Bank. Basis of Financial Statement Presentation: The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") and include the accounts of the Parent Company and all wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosed amount of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. The Corporation evaluates subsequent events through the date of the filing of this report with the Securities and Exchange Commission ("SEC").
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash: Cash and cash equivalents consists of cash and due from banks and interest bearing deposits with other banks, which includes restricted cash. Restricted cash comprises cash balances required to be maintained with the Federal Reserve Bank ("FRB"), based on customer transaction deposit account levels, and cash balances provided as collateral on derivative contracts and other contracts. See Note 2, "Restrictions on Cash and Cash Equivalents" for additional information.
FRB and Federal Home Loan Bank (FHLB) Stock	FRB and FHLB Stock: The Bank is a member of the FRB and FHLB and is required by federal law to hold stock in these institutions according to predetermined formulas. These restricted investments are carried at cost on the consolidated balance sheets and are periodically evaluated for impairment.
Investments	Investments: Debt securities are classified as held to maturity ("HTM") at the time of purchase when the Corporation has both the intent and ability to hold these investments until they mature. Such debt securities are carried at cost, adjusted for amortization of premiums and accretion of discounts using the effective yield method. The Corporation does not engage in trading activities; however, since the investment portfolio serves as a source of liquidity, most debt securities are classified as available for sale ("AFS"). AFS securities are carried at estimated fair value with the related unrealized holding gains and losses reported in shareholders’ equity as a component of other comprehensive income, net of tax. Realized securities gains and losses are computed using the specific identification method and are recorded on a trade date basis. Securities are evaluated periodically to determine whether declines in value are other-than-temporary. Impaired debt securities are determined to be other-than-temporarily impaired if the Corporation concludes at the balance sheet date that it has the intent to sell, or believes it will more likely than not be required to sell, an impaired debt security before a recovery of its amortized cost basis. Credit losses on other-than-temporarily impaired debt securities are recorded through earnings, regardless of the intent or the requirement to sell. Credit loss is measured as the difference between the present value of an impaired debt security’s expected cash flows and its amortized cost. Non-credit related other-than-temporary impairment ("OTTI") charges are recorded as decreases to accumulated other comprehensive income as long as the Corporation has no intent or expected requirement to sell the impaired debt security before a recovery of its amortized cost basis. The Corporation early adopted ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivative and Hedging, and Topic 825, Financial Instruments," in the third quarter of 2019, which permitted the one-time reclassification of certain HTM securities to AFS under Topic 815, specific to the transition guidance of ASU update 2017-12, which the Corporation adopted on January 1, 2019. See “Note 3 - Investment Securities” for additional information on this reclassification. The portion of this standards update related to codification improvements specific to Topic 326 will be implemented upon the Corporation’s adoption of ASU 2016-13 in the first quarter of 2020. Additional codification improvements to Topic 825, specifically ASU 2016-01, which the Corporation adopted as of January 1, 2018, did not have an impact on the Corporation's consolidated financial statements.
Fair Value Option	Fair Value Option: The Corporation has elected to measure mortgage loans held for sale at fair value. Derivative financial instruments related to mortgage banking activities are also recorded at fair value, as detailed under the heading "Derivative Financial Instruments," below. The Corporation determines fair value for its mortgage loans held for sale based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Changes in fair values during the period are recorded as components of mortgage banking income on the consolidated statements of income. Interest income earned on mortgage loans held for sale is classified in interest income on the consolidated statements of income.
Loans and Revenue Recognition	Loans and Lease Receivables : Loan and leases are stated at their principal amount outstanding, except for mortgage loans held for sale, which are carried at fair value. Interest income on loans is accrued as earned. Unearned income on lease financing receivables is recognized on a basis which approximates the effective yield method. In general, a loan or lease is placed on non-accrual status once it becomes 90 days delinquent as to principal or interest. In certain cases a loan or lease may be placed on non-accrual status prior to being 90 days delinquent if there is an indication that the borrower is having difficulty making payments, or the Corporation believes it is probable that all amounts will not be collected according to the contractual terms of the loan or lease agreement. When interest accruals are discontinued, unpaid interest previously credited to income is reversed. Non-accrual loans and leases may be restored to accrual status when all delinquent principal and interest has been paid currently for six consecutive months or the loan or lease is considered secured and in the process of collection. The Corporation generally applies payments received on non-accruing loans and leases to principal until such time as the principal is paid off, after which time any payments received are recognized as interest income. If the Corporation believes that all amounts outstanding on a non-accrual loan or lease will ultimately be collected, payments received subsequent to its classification as a non-accrual loan or lease are allocated between interest income and principal. A loan or lease that is 90 days delinquent may continue to accrue interest if the loan or lease is both adequately secured and is in the process of collection. Past due status is determined based on contractual due dates for loan payments. An adequately secured loan or lease is one that has collateral with a supported fair value that is sufficient to discharge the debt, and/or has an enforceable guarantee from a financially responsible party. A loan or lease is considered to be in the process of collection if collection is proceeding through legal action or through other activities that are reasonably expected to result in repayment of the debt or restoration to current status in the near future. Loans and leases deemed to be a loss are written off through a charge against the allowance for loan or lease losses. Closed-end consumer loans are generally charged off when they become 120 days past due ( 180 days for open-end consumer loans) if they are not adequately secured by real estate. All other loans and leases are evaluated for possible charge-off when it is probable that the balance will not be collected, based on the ability of the borrower to pay and the value of the underlying collateral. Principal recoveries of loans or leases previously charged off are recorded as increases to the allowance for loan or lease losses.
Loan Origination Fees and Costs	Loan Origination Fees and Costs: Loan origination fees and the related direct origination costs are deferred and amortized over the life of the loan as an adjustment to interest income using the effective yield method. For mortgage loans sold, net loan origination fees and costs are included in the gain or loss on sale of the related loan, as components of mortgage banking.
Troubled Debt Restructurings (TDRs)	Troubled Debt Restructurings ("TDRs"): Loans whose terms are modified are classified as TDRs if it is determined that those borrowers are experiencing financial difficulty and the Corporation grants the borrowers concessions. Concessions, whether negotiated or imposed by bankruptcy, granted under a TDR typically involve a temporary deferral of scheduled loan payments, an extension of a loan’s stated maturity date or a reduction in the interest rate. Non-accrual TDRs can be restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after modification.
Allowance for Credit Losses	Allowance for Credit Losses: The allowance for credit losses consists of the allowance for loan and lease losses and the reserve for unfunded lending commitments. The allowance for loan and lease losses represents management’s estimate of incurred losses in the loan and lease portfolio as of the balance sheet date and is recorded as a reduction to loans and leases. The reserve for unfunded lending commitments represents management’s estimate of incurred losses in its unfunded loan commitments and other off-balance sheet credit exposures, such as letters of credit, and is recorded in other liabilities on the consolidated balance sheets. The allowance for credit losses is increased by charges to expense, through the provision for credit losses, and decreased by charge-offs, net of recoveries. Management believes that the allowance for loan and lease losses and the reserve for unfunded lending commitments are adequate as of the balance sheet date; however, future changes to the allowance or reserve may be necessary based on changes in any of the factors discussed in the following paragraphs. Maintaining an appropriate allowance for credit losses is dependent upon various factors, including the ability to identify potential problem loans and leases in a timely manner. For commercial loans, commercial mortgages and construction loans to commercial borrowers, an internal risk rating process is used. The Corporation believes that internal risk ratings are the most relevant credit quality indicator for these types of loans. The migration of loans through the various internal risk rating categories is a significant component of the allowance for credit loss methodology for these loans, which bases the probability of default on this migration. Assigning risk ratings involves judgment. The Corporation's loan review officers provide a separate assessment of risk rating accuracy. Risk ratings may be changed based on the ongoing monitoring procedures performed by loan officers or credit administration staff, or if specific loan review assessments identify a deterioration or an improvement in the loan. The following is a summary of the Corporation's internal risk rating categories: • Pass : These loans do not currently pose undue credit risk and can range from the highest to average quality, depending on the degree of potential risk. • Special Mention : These loans have a heightened credit risk, but not to the point of justifying a classification of substandard. Loans in this category are currently acceptable, but are nevertheless potentially weak. • Substandard or Lower : These loans are inadequately protected by current sound worth and paying capacity of the borrower. There exists a well-defined weakness or weaknesses that jeopardize the normal repayment of the debt. The Corporation does not assign internal risk ratings for smaller balance, homogeneous loans and leases, such as home equity, residential mortgage, consumer, lease receivables and construction loans to individuals secured by residential real estate. For these loans and leases, the most relevant credit quality indicator is delinquency status. The migration of loans and leases through the various delinquency status categories is a significant component of the allowance for credit loss methodology for these loans and leases, which bases the probability of default on this migration. The Corporation’s allowance for loan and lease losses includes: 1) specific allowances allocated to loans and leases evaluated for impairment under the Financial Accounting Standards Board's Accounting Standards Codification ("ASC") Section 310-10-35; and 2) allowances calculated for pools of loans evaluated for impairment under ASC Subtopic 450-20. A loan or lease is considered to be impaired if it is probable that all amounts will not be collected according to the contractual terms of the loan or lease agreement. Impaired loans and leases consist of all loans and leases on non-accrual status and accruing TDRs. An allowance for loan and lease losses is established for an impaired loan or lease if its carrying value exceeds its estimated fair value. Impaired loans and leases to borrowers with total outstanding commitments greater than or equal to $1.0 million are evaluated individually for impairment. Impaired loans and leases to borrowers with total outstanding commitments less than $1.0 million are pooled and evaluated for impairment collectively. All loans and leases evaluated for impairment under ASC Section 310-10-35 are measured for losses on a quarterly basis. As of December 31, 2019 and 2018 , substantially all of the Corporation’s impaired loans and leases to borrowers with total outstanding loan or lease balances greater than or equal to $1.0 million were measured based on the estimated fair value of each loan or lease’s collateral. Collateral could be in the form of real estate, in the case of impaired commercial mortgages and construction loans, or business assets, such as accounts receivable or inventory, in the case of commercial and industrial loans. Commercial and industrial loans may also be secured by real property. For loans and leases secured by real estate, estimated fair values are determined primarily through appraisals performed by state certified third-party appraisers, discounted to arrive at expected net sale proceeds. For collateral dependent loans, estimated real estate fair values are also net of estimated selling costs. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated appraisal of the real estate is necessary. This decision is based on various considerations, including: the age of the most recent appraisal; the loan-to-value ratio based on the original appraisal; the condition of the property; the Corporation’s experience and knowledge of the real estate market; the purpose of the loan or lease; market factors; payment status; the strength of any guarantors; and the existence and age of other indications of value such as broker price opinions, among others. The Corporation generally obtains updated appraisals performed by state certified third-party appraisers for impaired loans and leases secured predominantly by real estate every 12 months. As of December 31, 2019 and 2018 , approximately 93% and 89% , respectively, of impaired loans or leases with principal balances greater than or equal to $1.0 million , whose primary collateral is real estate, were measured at estimated fair value using appraisals performed by state certified third-party appraisers that had been updated within the preceding 12 months. When updated appraisals are not obtained for loans and leases secured by real estate and evaluated for impairment under ASC Section 310-10-35, fair values are estimated based on the original appraisal values, as long as the original appraisal indicated an acceptable loan-to-value position and, in the opinion of the Corporation's internal credit administration staff, there has not been a significant deterioration in the collateral value since the original appraisal was performed. For impaired loans and leases with principal balances greater than or equal to $1.0 million secured by non-real estate collateral, such as accounts receivable or inventory, estimated fair values are determined based on borrower financial statements, inventory listings, accounts receivable agings or borrowing base certificates. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Liquidation or collection discounts are applied to these assets based upon existing loan evaluation policies. All loans and leases not evaluated for impairment under ASC Section 310-10-35 are evaluated for impairment under ASC Subtopic 450-20, using a pooled loss evaluation approach. Loans and leases are segmented into pools with similar characteristics and a consistently developed loss factor is then applied to all loans in these pools. Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on class segments. For commercial loans, class segments include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments are based on collateral types and include direct consumer installment loans, home equity loans and indirect automobile loans. The Corporation segments its loan and lease portfolio by general loan and lease type, or "portfolio segments," as presented in the table under the heading, "Loans and leases, net of unearned income," within Note 4, "Loans and Leases and Allowance for Credit Losses." Certain portfolio segments are further disaggregated and evaluated collectively for impairment based on "class segments," which are largely based on the type of collateral underlying each loan and lease. For commercial loans, class segments include loans secured by collateral and unsecured loans. Construction loan class segments include loans secured by commercial real estate, loans to commercial borrowers secured by residential real estate and loans to individuals secured by residential real estate. Consumer loan class segments are based on collateral types and include direct consumer installment loans and indirect automobile loans. The Corporation calculates allowance for loan and lease loss allocation needs for loans evaluated under ASC Subtopic 450-20 through the following procedures: • The loans and leases are segmented into pools with similar characteristics, as noted above. Commercial loans, commercial mortgages and construction loans to commercial borrowers are further segmented into separate pools based on internally assigned risk ratings. Residential mortgages, home equity loans, consumer loans, and lease receivables are further segmented into separate pools based on delinquency status; • A loss rate is calculated for each pool through an analysis of historical losses as loans and leases migrate through the various risk rating or delinquency categories. Estimated loss rates are based on a probability of default and a loss rate forecast; • The loss rate is adjusted to consider qualitative factors, such as economic conditions and trends; and • The resulting adjusted loss rate is applied to the balance of the loans and leases in the pool to arrive at the allowance allocation for the pool. The allocation of the allowance for credit losses is reviewed to evaluate its appropriateness in relation to the overall risk profile of the loan and lease portfolio. The Corporation considers risk factors such as: local and national economic conditions; trends in delinquencies and non-accrual loans and leases; the diversity of borrower industry types; and the composition of the portfolio by loan and lease type.
Premises and Equipment	Premises and Equipment: Premises and equipment are stated at cost, less accumulated depreciation and amortization. The provision for depreciation and amortization is generally computed using the straight-line method over the estimated useful lives of the related assets, which are a maximum of 50 years for buildings and improvements, 8 years for furniture and 5 years
Other Real Estate Owned	Other Real Estate Owned ("OREO"): Assets acquired in settlement of mortgage loan indebtedness are recorded as OREO and are included in other assets on the consolidated balance sheets, initially at the lower of the estimated fair value of the asset, less estimated selling costs, or the carrying amount of the loan. Costs to maintain the assets and subsequent gains and losses on sales are included in other non-interest expense on the consolidated statements of income.
Mortgage Servicing Rights	Mortgage Servicing Rights ("MSRs"): The estimated fair value of MSRs related to residential mortgage loans sold and serviced by the Corporation is recorded as an asset upon the sale of such loans. MSRs are amortized as a reduction to servicing income over the estimated lives of the underlying loans.
Derivative Financial Instruments	Derivative Financial Instruments: The Corporation manages its exposure to certain interest rate and foreign currency risks through the use of derivatives. None of the Corporation's outstanding derivative contracts are designated as hedges and none are entered into for speculative purposes. Derivative instruments are carried at fair value, with changes in fair value recognized in earnings as components of non-interest income or non-interest expense on the consolidated statements of income. Derivative contracts create counterparty credit risk with both the Corporation's customers and with institutional derivative counterparties. The Corporation manages counterparty credit risk through its credit approval processes, monitoring procedures and obtaining adequate collateral, when the Corporation determines it is appropriate to do so and in accordance with counterparty contracts. Mortgage Banking Derivatives In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured. Interest Rate Swaps The Corporation enters into interest rate swaps with certain qualifying commercial loan customers to meet their interest rate risk management needs. The Corporation simultaneously enters into interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of these interest rate swaps is that the customer pays a fixed rate of interest and the Corporation receives a floating rate. The Bank exceeds $10 billion in total assets and is required to clear all eligible interest rate swap contracts with a central counterparty. As a result, the Bank is subject to the regulations of the Commodity Futures Trading Commission. Foreign Exchange Contracts The Corporation enters into foreign exchange contracts to accommodate the needs of its customers. Foreign exchange contracts are commitments to buy or sell foreign currency on a specific date at a contractual price. The Corporation limits its foreign exchange exposure with customers by entering into contracts with institutional counterparties to mitigate its foreign exchange risk. The Corporation also holds certain amounts of foreign currency with international correspondent banks ("Foreign Currency Nostro Accounts"). The Corporation limits the total overnight net foreign currency open positions, which is defined as an aggregate of all outstanding contracts and Foreign Currency Nostro Account balances, to $500,000
Balance Sheet Offsetting	Balance Sheet Offsetting: Although certain financial assets and liabilities may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements, the Corporation elects to not offset such qualifying assets and liabilities. The Corporation is a party to interest rate swap transactions with financial institution counterparties and customers. Under these agreements, the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. Cash collateral is posted by the party with a net liability position in accordance with contract thresholds and can be used to settle the fair value of the interest rate swap agreements in the event of default. A daily settlement occurs through a clearing agent for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through a daily clearing agent. As a result, the total fair values of interest rate swap derivative assets and derivative liabilities recognized on the consolidated balance sheets are not equal and offsetting. The Corporation is also a party to foreign currency exchange contracts with financial institution counterparties, under which the Corporation has the right to net-settle multiple contracts with the same counterparty in the event of default on, or termination of, any one contract. As with interest rate swap contracts, cash collateral is posted by the party with a net liability position in accordance with contract thresholds and can be used to settle the fair value of the foreign currency exchange contracts in the event of default.
Income Taxes	Income Taxes: The Corporation utilizes the asset and liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. In assessing the realizability of deferred tax assets ("DTAs"), management considers whether it is more likely than not that some portion or all of the DTAs will not be realized. The ultimate realization of DTAs is dependent upon the generation of future taxable income and tax planning strategies which will create taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, the amount of taxes paid in available carryback years, projected future taxable income, and, if necessary, tax planning strategies in making this assessment. A valuation allowance is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized. ASC Topic 740, "Income Taxes" creates a single model to address uncertainty in tax positions, and clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in an enterprise's financial statements. It also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The liability for unrecognized tax benefits is included in other liabilities within the consolidated balance sheets. Effective January 1, 2018, the Corporation adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This standards update permits a reclassification from accumulated other comprehensive income ("AOCI") to retained earnings of the stranded tax effects resulting from the application of the Tax Cuts and Jobs Act of 2017 ("Tax Act"), which changed the federal corporate income tax rate from a top rate of 35% to a flat rate of 21%. Upon adoption, the Corporation elected to reclassify $7.1 million
Stock-Based Compensation	Stock-Based Compensation: The Corporation grants equity awards to employees, consisting of stock options, restricted stock, restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs") under its Amended and Restated Equity and Cash Incentive Compensation Plan ("Employee Equity Plan"). In addition, employees may purchase stock under the Corporation’s Employee Stock Purchase Plan ("ESPP"). The Corporation also grants equity awards to non-employee members of its board of directors and subsidiary bank board of directors under the 2011 Directors’ Equity Participation Plan, which was amended and approved by shareholders as the Amended and Restated Directors’ Equity Participation Plan in 2019 ("Directors’ Plan"). Under the Directors’ Plan, the Corporation can grant equity awards to non-employee holding company and subsidiary bank directors in the form of stock options, restricted stock, RSUs or common stock. Recent grants of equity awards under the Directors’ Plan have been limited to RSUs. Equity awards issued under the Employee Equity Plan are generally granted annually and become fully vested over or after a three-year vesting period. The vesting period for non-performance-based awards represents the period during which employees are required to provide service in exchange for such awards. Equity awards under the Directors' Plan are generally granted annually and become fully vested after a one-year vesting period. Certain events, as defined in the Employee Equity Plan and the Directors' Plan, result in the acceleration of the vesting of equity awards. Restricted stock, RSUs and PSUs earn dividends during the vesting period, which are forfeitable if the awards do not vest. The fair value of stock options, restricted stock and RSUs granted to employees is recognized as compensation expense over the vesting period for such awards. Compensation expense for PSUs is also recognized over the vesting period, however, compensation expense for PSUs may vary based on the expectations for actual performance relative to defined performance measures.
Disclosures about Segments of an Enterprise and Related Information	Disclosures about Segments of an Enterprise and Related Information : The Corporation does not have any operating segments which require disclosure of additional information.
Financial Guarantees	Financial Guarantees : Financial guarantees, which consist primarily of standby and commercial letters of credit, are accounted for by recognizing a liability equal to the fair value of the guarantees and crediting the liability to income over the term of the guarantee. Fair value is estimated based on the fees currently charged to enter into similar agreements with similar terms.
Goodwill and Intangible Assets	Goodwill and Intangible Assets : The Corporation accounts for its acquisitions using the purchase accounting method. Purchase accounting requires that all assets acquired and liabilities assumed, including certain intangible assets that must be recognized, be recorded at their estimated fair values as of the acquisition date. Any purchase price exceeding the fair value of net assets acquired is recorded as goodwill. During the fourth quarter of 2019, the Corporation early adopted ASU 2017-04 "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This standards update eliminates the requirement to perform the “step two” impairment test, which the Corporation has not needed to perform since its impairment test completed in 2012. The Corporation performed a qualitative analysis, as permitted in Topic 350, in 2019 and no impairment indicators were identified through this analysis. Goodwill is not amortized to expense, but is tested for impairment at least annually. Write-downs of the balance, if necessary as a result of the impairment test, are charged to expense in the period in which goodwill is determined to be impaired. The Corporation performs its annual test of goodwill impairment as of October 31st of each year. If certain events occur which indicate goodwill might be impaired between annual tests, goodwill would be tested when such events occur.
Variable Interest Entities	Variable Interest Entities ("VIEs") : ASC Topic 810 provides guidance on when to consolidate certain VIEs in the financial statements of the Corporation. VIEs are entities in which equity investors do not have a controlling financial interest or do not have sufficient equity at risk for the entity to finance activities without additional financial support from other parties. VIEs are assessed for consolidation under ASC Topic 810 when the Corporation holds variable interests in these entities. The Corporation consolidates VIEs when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has the power to make decisions that most significantly affect the economic performance of the VIE and has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Subsidiary Trusts The Parent Company owns all of the common stock of three subsidiary trusts, which have issued securities (Trust Preferred Securities) in conjunction with the Parent Company issuing junior subordinated deferrable interest debentures to the trusts. The terms of the junior subordinated deferrable interest debentures are the same as the terms of the Trust Preferred Securities ("TruPS"). The Parent Company’s obligations under the debentures constitute a full and unconditional guarantee by the Parent Company of the obligations of the trusts. The provisions of ASC Topic 810 related to subsidiary trusts, as interpreted by the SEC, disallow consolidation of subsidiary trusts in the financial statements of the Corporation. As a result, TruPS are not included on the Corporation’s consolidated balance sheets. The junior subordinated debentures issued by the Parent Company to the subsidiary trusts, which have the same total balance and rate as the combined equity securities and TruPS issued by the subsidiary trusts, remain in long-term debt. See "Note 9 - Short-Term Borrowings and Long-Term Debt," for additional information. Tax Credit Investments The Corporation makes investments in certain community development projects, the majority of which, generate tax credits under various federal programs, including qualified affordable housing projects, New Markets Tax Credit Investments ("NMTC") projects and historic rehabilitation projects (collectively, "Tax Credit Investments" or "TCIs"). These investments are made throughout the Corporation's market area as a means of supporting the communities it serves. The Corporation typically acts as a limited partner or member of a limited liability company in its TCIs and does not exert control over the operating or financial policies of the partnership or limited liability company. Tax credits earned are subject to recapture by federal taxing authorities based upon compliance requirements to be met at the project level. Because the Corporation owns 100% of the equity interests in its NMTC, these investments were consolidated based on ASC Topic 810 as of December 31, 2019 and 2018 . Investments in affordable housing projects were not consolidated based on management's assessment of the provisions of ASC Topic 810. TCIs are tested for impairment when events or changes in circumstances indicate that it is more likely than not that the carrying amount of the investment will not be realized. An impairment loss is measured as the amount by which the current carrying value exceeds its aggregated remaining value of the tax benefits of the investment. There were no impairment losses recognized for the Corporation’s TCIs in 2019 , 2018 or 2017
Fair Value Measurements	Fair Value Measurements: Assets and liabilities are categorized in a fair value hierarchy for the inputs to valuation techniques used to measure assets and liabilities at fair value using the following three categories (from highest to lowest priority): • Level 1 - Inputs that represent quoted prices for identical instruments in active markets. • Level 2 - Inputs that represent quoted prices for similar instruments in active markets, or quoted prices for identical instruments in non-active markets. Also includes valuation techniques whose inputs are derived principally from observable market data other than quoted prices, such as interest rates or other market-corroborated means. • Level 3 - Inputs that are largely unobservable, as little or no market data exists for the instrument being valued. The Corporation has categorized all assets and liabilities required to be measured at fair value on both a recurring and nonrecurring basis into the above three levels. See "Note 19 - Fair Value Measurements," for additional details. In 2008, the Corporation received Class B restricted shares of Visa, Inc. ("Visa") as part of Visa’s initial public offering. In accordance with ASC Update 2016-01, these securities are considered equity securities without readily determinable fair values. As such, the approximately 133,000 Visa Class B shares owned as of December 31, 2019 were carried at a zero cost basis.
Revenue Recognition	Revenue Recognition: The Corporation adopted ASC Update 2014-09, "Revenue from Contracts with Customers" using the modified retrospective method applied to all open contracts as of January 1, 2018 with no material impact on its consolidated financial statements. This update established a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle prescribed by this standards update is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The sources of revenue for the Corporation are interest income from loans, leases and investments, net of interest expense on deposits and borrowings, and non-interest income. Non-interest income is earned from various banking and financial services that the Corporation offers through its subsidiary bank. Revenue is recognized as earned based on contractual terms, as transactions occur, or as services are provided. Following is further detail of the various types of revenue the Corporation earns and when it is recognized: Interest income : Interest income is recognized on an accrual basis according to loan and lease agreements, securities contracts or other such written contracts. Wealth management services: Consists of trust commission income, brokerage income, money market income and insurance commission income. Trust commission income consists of advisory fees that are based on market values of clients' managed portfolios and transaction fees for fiduciary services performed, both of which are recognized as earned. Brokerage income includes advisory fees which are recognized as earned on a monthly basis and transaction fees that are recognized when transactions occur. Money market income is based on the balances held in trust accounts and is recognized monthly. Insurance commission income is earned and recognized when policies are originated. Currently, no investment management and trust service income is based on performance or investment results. Commercial and consumer banking income: Consists of cash management, overdraft, non-sufficient fund fees and other service charges on deposit accounts as well as branch fees, automated teller machine fees, debit and credit card income and merchant services fees. Also included are letter of credit fees, foreign exchange income and commercial loan interest rate swap fees. Revenue is primarily transactional and recognized when earned, at the time the transactions occur. Mortgage banking income: Consists of gains or losses on the sale of residential mortgage loans and mortgage loan servicing income. Other Income: Includes gains on sales of Small Business Association loans, cash surrender value of life insurance, and other miscellaneous income.
Leases	Leases: Effective January 1, 2019, the Corporation adopted ASU 2016-02, "Leases (Topic 842)." This standards update requires a lessee to recognize for all leases with an initial term greater than twelve months: (1) a right-of-use ("ROU") asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term; and (2) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, each measured on a discounted basis. The Corporation adopted this standards update in the first quarter of 2019 using the modified retrospective method, which eliminates the requirement to restate the earliest prior period presented in an entity’s financial statements. As such, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019 and continue to be reported in accordance with previous guidance (Topic 840). This standards update provides for a number of practical expedients in transition. The Corporation elected to apply the package of practical expedients permitted within the new standard, which, among other things, allowed it to carryforward the prior conclusions on lease identification, lease classification and initial direct costs. In addition, the Corporation elected to not separate lease and non-lease components. The Corporation did not elect the practical expedient to apply hindsight in determining the lease term and in assessing impairment of the ROU assets. As a lessee, the majority of the operating lease portfolio consists of real estate leases for the Corporation's branches, land and office space. The operating leases have remaining lease terms of 1 year to 20 years , some of which include options to extend the leases for 5 years or more. ROU assets and lease liabilities are not recognized for leases with an initial term of 12 months or less. The Corporation does not have any finance leases as the lessee. Certain real estate leases have lease payments that adjust based on annual changes in the Consumer Price Index ("CPI"). The leases that are dependent upon CPI are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Operating lease expense represents fixed lease payments for operating leases recognized on a straight-line basis over the applicable lease term. Variable lease expense represents the payment of real estate taxes, insurance and common area maintenance based on the Corporation's pro-rata share. Sublease income consists mostly of operating leases for space within the Corporation's offices and branches and is recorded as a reduction to net occupancy expense on the consolidated statements of income. See "Note 17 - Leases" for additional information and expanded lessee disclosures.
Defined Benefit Pension Plans	Defined Benefit Pension Plan: Net periodic pension costs are funded based on the requirements of federal laws and regulations. The determination of net periodic pension costs is based on assumptions about future events that will affect the amount and timing of required benefit payments under the plan. These assumptions include demographic assumptions such as retirement age and mortality, a discount rate used to determine the current benefit obligation, form of payment election and a long-term expected rate of return on plan assets. Net periodic pension expense includes interest cost, based on the assumed discount rate, an expected return on plan assets, amortization of prior service cost or credit and amortization of net actuarial gains or losses. For the Corporation, there is no service cost as the plan was curtailed in 2008, with no additional benefits accruing. Net periodic pension cost is recognized in salaries and employee benefits on the consolidated statements of income. For additional details, see "Note 16 - Employee Benefit Plans."
Recently Issued Accounting Standards	Recently Issued Accounting Standards: Standard Description Date of Anticipated Adoption Effect on Financial Statements ASC Update 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The new impairment model prescribed by this standards update is a single impairment model for all financial assets (i.e., loans and HTM investments). The recognition of credit losses would be based on an entity’s current estimate of expected losses (referred to as the Current Expected Credit Loss model, or "CECL"), as opposed to recognition of losses only when they are probable under current GAAP. This update also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This adjustment will also be recognized in regulatory capital. This update is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. In November 2018, ASC Update 2018-19, "Codifications Improvements to Topic 326, Financial Instruments - Credit Losses" was issued which clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASC Update 2019-04, 2019-05 and 2019-11 were issued to provide certain clarifications and transition relief to adopting this standards update. First Quarter of 2020 The Corporation intends to adopt these standards updates effective with its March 31, 2020 quarterly report on Form 10-Q. The allowance for credit losses ("ACL") will be based on the Corporation’s historical loss experience, borrower characteristics, forecasts of future economic conditions and other relevant factors. The Corporation will use models and other loss estimation techniques that are responsive to changes in forecasted economic conditions to interpret borrower and economic factors in order to estimate the ACL. The Corporation will also apply qualitative factors to account for information that may not be reflected in quantitatively derived results, or other relevant factors to ensure the ACL reflects the best estimate of current expected credit losses. Preliminary expected loss estimates have been determined and the Corporation believes that the total allowance for credit losses will increase between 25% to 35% as a result of the adoption of CECL. The Corporation is in the process of finalizing the review of the most recent model run, conducting scenario testing, and finalizing certain assumptions including economic forecasts and qualitative adjustments. The Corporation will be adopting the option to phase in over a three-year period the day-one impact of this standards update on regulatory capital afforded to it in the Final Rule published in the Federal Register on February 14, 2019 by Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation. ASC Update 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement This update changes the fair value measurement disclosure requirements of ASC Topic 820 "Fair Value Measurement." Among other things, the update modifies the disclosure objective paragraphs of ASC 820 to eliminate: (1) "at a minimum" from the phrase "an entity shall disclose at a minimum;" and (2) other similar disclosure requirements to promote the appropriate exercise of discretion by entities. First Quarter 2020 The Corporation intends to adopt this standards update effective with its March 31, 2020 quarterly report on Form 10-Q. This standard will impact the Corporation's disclosures relating to fair value measurement. The Corporation does not expect the adoption of this update to have a material impact on its consolidated financial statements. Standard Description Date of Anticipated Adoption Effect on Financial Statements ASC Update 2018-14 Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans This update amends ASC Topic 715-20 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. This update is effective for annual reporting periods beginning after December 15, 2020. Early adoption is permitted. First Quarter 2021 The Corporation intends to adopt this standards update effective with its March 31, 2021 quarterly report on Form 10-Q. This standard will impact the Corporation's disclosure relating to employee benefit plans, but the Corporation does not expect the adoption of this update to have a material impact on its consolidated financial statements. ASC Update 2018-15 Intangibles - Goodwill and Other - Internal Use Software (Topic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract This update requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC Subtopic 350-40 to determine which implementation costs to capitalize as assets. This update is effective for annual or interim reporting periods beginning after December 15, 2019. Early adoption is permitted. First Quarter 2020 The Corporation intends to adopt this standards update effective with its March 31, 2020 quarterly report on Form 10-Q and does not expect the adoption of this update to have a material impact on its consolidated financial statements. ASC Update 2019-12 Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes This update simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. It also improves consistent application of, and simplifies GAAP for, other areas of Topic 740 by clarifying and amending existing guidance. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted. First Quarter 2021 The Corporation intends to adopt this standards update effective with its March 31, 2021 quarterly report on Form 10-Q and does not expect the adoption of this update to have a material impact on its consolidated financial statements.
