Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of Fulton Financial Corporation (the "Corporation") have been prepared in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities as of the date of the financial statements as well as revenues and expenses during the period. Actual results could differ from those estimates. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2017. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The Corporation evaluates subsequent events through the date of filing of this Form 10-Q with the U.S. Securities and Exchange Commission ("SEC"). Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Codification ("ASC") Update 2014-09, "Revenue from Contracts with Customers." This standards 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 standard applies to all contracts with customers, except those that are within the scope of other topics in the FASB ASC. The Corporation adopted this standard, and all subsequent Accounting Standards Updates ("ASU") that modified the standard, on January 1, 2018 under the modified retrospective approach with no material impact on its consolidated financial statements. The Corporation evaluated the impact of the adoption of ASC Update 2014-09 on its consolidated financial statements and did not identify any significant changes in the timing of revenue recognition as a result of this amended guidance. The sources of revenue for the Corporation are interest income from loans 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 banks. 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 agreements, securities contracts or other such written contracts and is outside the scope of ASC Update 2014-09. Investment management and trust 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. Service charges on deposit accounts: Consists of cash management, overdraft, non-sufficient fund fees and other service charges on deposit accounts. Revenue is primarily transactional and recognized when earned, at the time the transactions occur. Other service charges and fees: Consists of branch fees, automated teller machine fees, debit card income and merchant services fees. These fees are primarily transactional, and revenue is recognized when transactions occur. Also included in other service charges and fees are letter of credit fees, foreign exchange income and commercial loan interest rate swap fees, which are outside the scope of ASC Update 2014-09. Mortgage banking income: Consists of gains or losses on the sale of residential mortgage loans and mortgage loan servicing income. These revenues are outside the scope of ASC Update 2014-09. Other Income: Includes credit card income, gains on sales of Small Business Association ("SBA") loans, cash surrender value of life insurance, and other miscellaneous income. These items are either outside the scope of ASC Update 2014-09 or are immaterial. In January 2016, the FASB issued ASC Update 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." ASC Update 2016-01 provides guidance regarding the income statement impact of equity investments held by an entity and the recognition of changes in fair value of financial liabilities when the fair value option is elected. This standard requires equity investments to be measured at fair value, with changes recorded in net income. This ASU also requires the use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes. ASC Update 2016-01 was effective for interim and annual reporting periods beginning after December 15, 2017. The Corporation adopted this standards update effective with its March 31, 2018 quarterly report on Form 10-Q and the adoption of ASC Update 2016-01 did not have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASC Update 2016-18, "Statement of Cash Flows - Restricted Cash." This standards update provides guidance regarding the presentation of restricted cash in the statement of cash flows. The update requires companies to include amounts generally described as restricted cash and restricted cash equivalents, along with cash and cash equivalents, when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. It also requires an entity to disclose the nature of the restrictions on cash and cash equivalents. ASC Update 2016-18 was effective for interim and annual reporting periods beginning after December 15, 2017. The adoption of ASC Update 2016-18 did not have a material impact on its consolidated financial statements; however, in the second quarter of 2018 on the Consolidated Statements of Cash Flows, the Corporation corrected an error related to the adoption of this standards update to include restricted cash along with cash and cash equivalents in the reconciliation of beginning-of-period and end-of-period total amounts. The change had no impact on net income or retained earnings. In addition, the Corporation will revise the Consolidated Statements of Cash Flows for the three months ended March 31, 2018 when the amounts are next presented in the first quarter of 2019. In February 2018, the FASB issued ASC Update 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASU 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 35% to 21%. This ASU is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Corporation adopted this standards update effective January 1, 2018 and elected to reclassify $7.1 million of stranded tax effects from AOCI to retained earnings at the beginning of the period of adoption. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release them as investments are sold or mature and as pension and post-retirement liabilities are extinguished. Recently Issued Accounting Standards In February 2016, the FASB issued ASC Update 2016-02, "Leases." ASC Update 2016-02 requires a lessee to recognize for all leases with an initial term greater than twelve months: (1) a “right-of-use” asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term; and (2) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis. ASC Update 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. In July 2018, the FASB also issued amendments to ASC Update 2016-02 (ASC Updates 2018-10 and 2018-11), which allow for an alternative transition method that eliminates the requirement to restate the earliest prior period presented in an entity’s financial statements. Entities that elect this transition method still adopt ASC Update 2016-02 using the modified retrospective transition method, but they recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. The Corporation expects to adopt ASC Update 2016-02 in the first quarter of 2019 using this alternative transition method. The Corporation expects to elect to apply the package of practical expedients permitted within the new standard, which, among other things, allows it to carryforward the historical lease classification, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. Based on preliminary evaluation, the right-of-use asset and corresponding lease obligation liability, which represents substantially all of the Corporation’s operating lease commitments, is expected to be less than 1% of the Corporation's total assets at adoption. The Corporation does not believe the new lease standard will materially affect its consolidated net income. This estimate is based primarily on the present value of the unpaid future minimum lease payments. The final amount recognized may be impacted by assumptions relating to lease renewals and extensions before the effective date, and the interest rate used to discount those future lease obligations. ASC Update 2016-02 requires lessors to classify leases as a sales-type, direct financing or operating lease. Substantially all of the Corporation's leasing activities as lessor are under direct financing leases and it does not expect the new standard to have a material effect on its financial statements related to these leases and does not expect a significant change in its leasing activities between now and time of adoption. In June 2016, the FASB issued ASC Update 2016-13, "Financial Instruments - Credit Losses." The new impairment model prescribed by this standards update is a single impairment model for all financial assets (i.e., loans and held to maturity 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 U.S. GAAP. ASU 2016-13 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. ASC Update 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted. The Corporation intends to adopt this standards update effective with its March 31, 2020 quarterly report on Form 10-Q. The Corporation is currently evaluating the impact of the adoption of ASC Update 2016-13 on its consolidated financial statements and disclosures. While the Corporation is currently unable to reasonably estimate the impact of adopting ASU 2016-13, it expects that the impact of adoption could be significantly influenced by the composition, characteristics and quality of its loan portfolio as well as the prevailing economic conditions and forecasts as of the adoption date. The Corporation’s steering committee and working group, which are comprised of individuals from various functional areas, are assessing processes, portfolio segmentation, systems requirements and solutions and resources to implement this new accounting standard. Current activities also include data gathering and building loss models. In addition, the Corporation has engaged a third-party consultant to assist with these implementation efforts. In January 2017, the FASB issued ASC Update 2017-04, "Intangibles - Goodwill and Other." This standards update eliminates Step 2 of the goodwill impairment test which measures the impairment amount. Identifying and measuring impairment will take place in a single quantitative step. In addition, no separate qualitative assessment for reporting units with zero or negative carrying amounts is required. Entities must disclose the existence of these reporting units and the amount of goodwill allocated to them. This update should be applied on a prospective basis, and an entity is required to disclose the nature of and reason for the change in accounting principle upon transition. ASC Update 2017-04 is effective for annual or interim goodwill impairment tests in reporting periods beginning after December 15, 2019. Early adoption is permitted. The Corporation intends to adopt this standards update effective with its 2020 goodwill impairment test and does not expect the adoption of ASC Update 2017-04 to have a material impact on its consolidated financial statements. In March 2017, the FASB issued ASC Update 2017-08, "Premium Amortization on Purchased Callable Debt Securities." This standards update requires that a company amortize the premium on callable debt securities to the earliest call date versus current U.S. GAAP which requires amortization over the contractual life of the securities. The amortization period for callable debt securities purchased at a discount would not be impacted by the new accounting standards update. This amendment is to be adopted on a modified retrospective basis with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. ASC Update 2017-08 is effective for annual or interim reporting periods beginning after December 15, 2018. Early adoption is permitted. The Corporation intends to adopt this standards update effective with its March 31, 2019 quarterly report on Form 10-Q and does not expect the adoption of ASC Update 2017-08 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASC Update 2018-13, "Fair Value Measurement - Disclosure Framework." This standards update changes the fair value measurement disclosure requirements of ASC 820 "Fair Value Measurement." Among other things, the ASU 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 “open ended” disclosure requirements to promote the appropriate exercise of discretion by entities. ASC Update 2018-13 is effective for annual or interim reporting periods beginning after December 15, 2019. Early adoption is permitted. 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 Fair Value Measurement disclosure but the Corporation does not expect the adoption of ASC Update 2018-13 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASC Update 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General." This standards update amends ASC 715-20 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. ASC Update 2018-14 is effective for annual reporting periods beginning after December 15, 2020. Early adoption is permitted. 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 ASC Update 2018-14 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASC Update 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software." This standards update requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets. ASC Update 2018-15 is effective for annual or interim reporting periods beginning after December 15, 2019. Early adoption is permitted. 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 ASC Update 2018-15 to have an impact on its consolidated financial statements. Reclassifications Certain amounts in the 2017 consolidated financial statements and notes have been reclassified to conform to the 2018 presentation. On the Consolidated Statements of Cash Flows, the net change in tax credit investments is presented as cash flows from investing activities. Prior to the quarter ended March 31, 2018, these cash flows were presented as cash flows from operating activities, included in the net increase (decrease) in other liabilities. The presentation of the cash flows for the nine months ended September 30, 2017 was changed to conform to this presentation, resulting in a $21.1 million decrease in net cash flows used in investing activities and a corresponding increase in net cash flows provided by operating activities. The change had no impact on net income or retained earnings. In addition, the Corporation will revise the Consolidated Statements of Cash Flows for each of the comparative 2017 periods in future filings.

Reclassifications

Certain amounts in the 2017 consolidated financial statements and notes have been reclassified to conform to the 2018 presentation. On the Consolidated Statements of Cash Flows, the net change in tax credit investments is presented as cash flows from investing activities. Prior to the quarter ended March 31, 2018, these cash flows were presented as cash flows from operating activities, included in the net increase (decrease) in other liabilities. The presentation of the cash flows for the nine months ended September 30, 2017 was changed to conform to this presentation, resulting in a $21.1 million decrease in net cash flows used in investing activities and a corresponding increase in net cash flows provided by operating activities. The change had no impact on net income or retained earnings. In addition, the Corporation will revise the Consolidated Statements of Cash Flows for each of the comparative 2017 periods in future filings.
