SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Sep. 30, 2018
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations – Orrstown Financial Services, Inc. and subsidiaries is a financial holding company that operates Orrstown Bank, a commercial bank with banking and financial advisory offices in Berks, Cumberland, Dauphin, Franklin, Lancaster, Perry and York Counties, Pennsylvania, and in Washington County, Maryland and Wheatland Advisors, Inc., a registered investment advisor non-bank subsidiary, headquartered in Lancaster, Pennsylvania. The Company operates in the community banking segment and engages in lending activities, including commercial, residential, commercial mortgages, construction, municipal, and various forms of consumer lending, and deposit services, including checking, savings, time, and money market deposits. The Company also provides fiduciary services, investment advisory, insurance and brokerage services. The Company and the Bank are subject to regulation by certain federal and state agencies and undergo periodic examinations by such regulatory authorities.
Basis of Presentation	Basis of Presentation – The accompanying condensed consolidated financial statements include the accounts of Orrstown Financial Services, Inc. and its wholly owned subsidiaries, the Bank and Wheatland. The Company has prepared these unaudited condensed consolidated financial statements in accordance with GAAP for interim financial information, SEC rules that permit reduced disclosure for interim periods, and Article 10 of Regulation S-X. In the opinion of management, all adjustments (all of which are of a normal recurring nature) that are necessary for a fair statement are reflected in the unaudited condensed consolidated financial statements. The December 31, 2017 consolidated balance sheet information contained in this Quarterly Report on Form 10-Q was derived from the 2017 audited consolidated financial statements. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’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. All significant intercompany transactions and accounts have been eliminated. Certain reclassifications have been made to prior year amounts to conform with current year classifications. The Company's management has evaluated all activity of the Company and concluded that subsequent events are properly reflected in the Company's consolidated financial statements and notes as required by GAAP. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change include the determination of the ALL and income taxes.
Concentration of Credit Risk	Concentration of Credit Risk – The Company grants commercial, residential, construction, municipal, and various forms of consumer lending to customers primarily in its market area of Berks, Cumberland, Dauphin, Franklin, Lancaster, Perry, and York Counties, Pennsylvania, and in Washington County, Maryland. Therefore the Company's exposure to credit risk is significantly affected by changes in the economy in those areas. Although the Company maintains a diversified loan portfolio, a significant portion of its customers’ ability to honor their contracts is dependent upon economic sectors for commercial real estate, including office space, retail strip centers, sales finance, sub-dividers and developers, and multi-family, hospitality, and residential building operators. Management evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if collateral is deemed necessary by the Company upon the extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies, but generally includes real estate and equipment.
Cash and Cash Equivalents	Cash and Cash Equivalents – Cash and cash equivalents include cash, balances due from banks, federal funds sold and interest-bearing deposits due on demand, all of which have original maturities of 90 days or less. Net cash flows are reported for customer loan and deposit transactions, loans held for sale, redemption (purchases) of restricted investments in bank stocks, and short-term borrowings.
Restricted Investments in Bank Stocks	Restricted Investments in Bank Stocks – Restricted investments in bank stocks consist of Federal Reserve Bank of Philadelphia stock, FHLB of Pittsburgh stock and Atlantic Community Bankers Bank stock. Federal law requires a member institution of the district Federal Reserve Bank and FHLB to hold stock according to predetermined formulas. Atlantic Community Bankers Bank requires its correspondent banking institutions to hold stock as a condition of membership. The restricted investment in bank stocks is carried at cost. Quarterly, management evaluates the bank stocks for impairment based on assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as operating performance, liquidity, funding and capital positions, stock repurchase history, dividend history and impact of legislative and regulatory changes.
Securities	Securities – The Company typically classifies debt securities as available for sale on the date of purchase. At September 30, 2018 and December 31, 2017, the Company had no held to maturity or trading securities. AFS securities are reported at fair value. Interest income and dividends are recognized in interest income on an accrual basis. Purchase premiums and discounts on debt securities are amortized to interest income using the interest method over the terms of the securities and approximate the level yield method. Changes in unrealized gains and losses, net of related deferred taxes, for AFS securities are recorded in AOCI. Realized gains and losses on securities are recorded on the trade date using the specific identification method and are included in noninterest income. AFS securities include investments that management intends to use as part of its asset/liability management strategy. Securities may be sold in response to changes in interest rates, changes in prepayment rates and other factors. The Company does not have the intent to sell any of its AFS securities that are in an unrealized loss position and it is more likely than not that the Company will not be required to sell these securities before recovery of their amortized cost. Management evaluates securities for OTTI on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components: OTTI related to other factors, which is recognized in OCI, and the remaining OTTI, which is recognized in earnings. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. The Company’s securities are exposed to various risks, such as interest rate risk, market risk, and credit risk. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the value of investments, it is at least reasonably possible that changes in risks in the near term would materially affect investment assets reported in the consolidated financial statements.
Loans Held for Sale	Loans Held for Sale – Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value. Gains and losses on loan sales (sales proceeds minus carrying value) are recorded in noninterest income.
Loans	Loans – The Company grants commercial loans; residential, commercial and construction mortgage loans; and various forms of consumer loans to its customers located principally in south central Pennsylvania and northern Maryland. The ability of the Company’s debtors to honor their contracts is dependent largely upon the real estate and general economic conditions in this area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the ALL, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and amortized as a yield adjustment over the respective term of the loan. For purchased loans that are not deemed impaired at the acquisition date, premiums and discounts are amortized or accreted as adjustments to interest income using the effective yield method. For all classes of loans, the accrual of interest income on loans, including impaired loans, ceases when principal or interest is past due 90 days or more or immediately if, in the opinion of management, full collection is unlikely. Interest will continue to accrue on loans past due 90 days or more if the collateral is adequate to cover principal and interest, and the loan is in the process of collection. Interest accrued, but not collected, at the date of placement on nonaccrual status, is reversed and charged against current interest income, unless fully collateralized. Subsequent payments received are either applied to the outstanding principal balance or recorded as interest income, depending upon management’s assessment of the ultimate collectability of principal. Loans are returned to accrual status, for all loan classes, when all the principal and interest amounts contractually due are brought current, the loan has performed in accordance with the contractual terms of the note for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is reasonably assured. Past due status is based on contractual terms of the loan. Loans, the terms of which are modified, are classified as TDRs if a concession was granted in connection with the modification, for legal or economic reasons, related to the debtor’s financial difficulties. Concessions granted under a TDR typically involve a temporary deferral of scheduled loan payments, an extension of a loan’s stated maturity date, a temporary reduction in interest rates, or granting of an interest rate below market rates given the risk of the transaction. If a modification occurs while the loan is on accruing status, it will continue to accrue interest under the modified terms. Nonaccrual TDRs may be restored to accrual status if scheduled principal and interest payments, under the modified terms, are current for six months after modification, and the borrower continues to demonstrate its ability to meet the modified terms. TDRs are evaluated individually for impairment on a quarterly basis including monitoring of performance according to their modified terms.
Allowance for Loan Losses	Allowance for Loan Losses – The ALL is evaluated on at least a quarterly basis, as losses are estimated to be probable and incurred, and, if deemed necessary, is increased through a provision for loan losses charged to earnings. Loan losses are charged against the ALL when management determines that all or a portion of the loan is uncollectible. Recoveries on previously charged-off loans are credited to the ALL when received. The ALL is allocated to loan portfolio classes on a quarterly basis, but the entire balance is available to cover losses from any of the portfolio classes when those losses are confirmed. Management uses internal policies and bank regulatory guidance in periodically evaluating loans for collectability and incorporates historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. See Note 4, Loans and Allowance for Loan Losses, for additional information.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments – Financial instruments include off-balance sheet credit commitments issued to meet customer financing needs, such as commitments to make loans and commercial letters of credit. These financial instruments are recorded when they are funded. The face amount represents the exposure to loss, before considering customer collateral or ability to repay. The Company maintains a reserve for probable losses on off-balance sheet commitments which is included in Other Liabilities.
Loans Serviced	Loans Serviced – The Bank administers secondary market mortgage programs available through the FHLB and the Federal National Mortgage Association and offers residential mortgage products and services to customers. The Bank originates single-family residential mortgage loans for immediate sale in the secondary market and retains the servicing of those loans.
Transfers of Financial Assets	Transfers of Financial Assets – Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Cash Surrender Value of Life Insurance	Cash Surrender Value of Life Insurance – The Company has purchased life insurance policies on certain employees. Life insurance is recorded at the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Premises and Equipment	Premises and Equipment – Buildings, improvements, equipment, furniture and fixtures are carried at cost less accumulated depreciation and amortization. Land is carried at cost. Depreciation and amortization has been provided generally on the straight-line method and is computed over the estimated useful lives of the various assets as follows: buildings and improvements, including leasehold improvements – 10 to 40 years; and furniture and equipment – 3 to 15 years. Leasehold improvements are amortized over the shorter of the lease term or the indicated life. Repairs and maintenance are charged to operations as incurred, while major additions and improvements are capitalized. Gain or loss on retirement or disposal of individual assets is recorded as income or expense in the period of retirement or disposal.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets – Goodwill is calculated as the purchase premium, if any, after adjusting for the fair value of net assets acquired in purchase transactions. Goodwill is not amortized but is reviewed for potential impairment on at least an annual basis, with testing between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit. Other intangible assets represent purchased assets that can be distinguished from goodwill because of contractual or other legal rights. The Company’s other intangible assets have finite lives and are amortized on either the sum of the years digits or straight line bases over their estimated lives, generally 10 years for deposit premiums and 10 to 15 years for customer lists.
Mortgage Servicing Rights	Mortgage Servicing Rights – The estimated fair value of MSRs related to loans sold and serviced by the Company 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 evaluated periodically for impairment by comparing the carrying amount to estimated fair value. Fair value is determined periodically through a discounted cash flows valuation performed by a third party. Significant inputs to the valuation include expected servicing income, net of expense, the discount rate and the expected life of the underlying loans. To the extent the amortized cost of the MSRs exceeds their estimated fair values, a valuation allowance is established for such impairment through a charge against servicing income on the consolidated statements of income. If the Company determines, based on subsequent valuations, that the impairment no longer exists or is reduced, the valuation allowance is reduced through a credit to earnings.
Foreclosed Real Estate	Foreclosed Real Estate – Real estate acquired through foreclosure or other means is initially recorded at the fair value of the related real estate collateral at the transfer date less estimated selling costs, and subsequently at the lower of its carrying value or fair value less estimated costs to sell. Fair value is usually determined based on an independent third party appraisal of the property or occasionally on a recent sales offer. Costs to maintain foreclosed real estate are expensed as incurred. Costs that significantly improve the value of the properties are capitalized.
Investments In Real Estate Partnerships	Investments in Real Estate Partnerships – The Company has a 99% limited partner interest in several real estate partnerships in central Pennsylvania. These investments are affordable housing projects, which entitle the Company to tax deductions and credits that expire through 2025. The Company accounts for its investments in affordable housing projects under the proportional amortization method when the criteria are met, which is limited to one investment entered into in 2015. Other investments are accounted for under the equity method of accounting.
Advertising	Advertising – The Company expenses advertising as incurred.
Repurchase Agreements	Repurchase Agreements – The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities which are included in short-term borrowings. Under these agreements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, these Repurchase Agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated balance sheets, while the securities underlying the Repurchase Agreements remaining are reflected in AFS securities. The repurchase obligation and underlying securities are not offset or netted. The Company does not enter into reverse Repurchase Agreements, so there is no offsetting to be performed with Repurchase Agreements. The right of setoff for a Repurchase Agreement resembles a secured borrowing, whereby the collateral would be used to settle the fair value of the Repurchase Agreement should the Company be in default (e.g., fail to make an interest payment to the counterparty). For the Repurchase Agreements, the collateral is held by the Company in a segregated custodial account under a third party agreement. Repurchase agreements are secured by GSE MBSs and mature overnight.
Share Compensation Plans	Share Compensation Plans – The Company has share compensation plans that cover employees and non-employee directors. Compensation expense relating to share-based payment transactions is measured based on the grant date fair value of the share award, including a Black-Scholes model for stock options. Compensation expense for all share awards is calculated and recognized over the employees’ or non-employee directors' service period, generally defined as the vesting period.
Income Taxes	Income Taxes – Income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of enacted tax law to taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties, if any, on income taxes as a component of income tax expense.
Loss Contingencies	Loss Contingencies – Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.
Treasury Stock	Treasury Stock – Common stock shares repurchased are recorded as treasury stock at cost.
Earnings Per Share	Earnings Per Share – Basic earnings per share represents income available to common stockholders divided by the weighted average number of common shares outstanding during the period. Restricted stock awards are included in weighted average common shares outstanding as they are earned. Diluted earnings per share includes additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares that may be issued by the Company relate solely to outstanding stock options and restricted stock awards and are determined using the treasury stock method. Treasury shares are not deemed outstanding for earnings per share calculations.
Comprehensive Income	Comprehensive Income – Comprehensive income consists of net income and OCI. OCI is limited to unrealized gains (losses) on securities available for sale for all years presented. Unrealized gains (losses) on securities available for sale, net of tax, was the sole component of AOCI at September 30, 2018 and December 31, 2017.
Fair Value	Fair Value – Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 10, Fair Value. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.
Segment Reporting	Segment Reporting – The Company operates in one significant segment – Community Banking. The Company’s non-community banking activities, principally related to Wheatland, are insignificant to the consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize 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. On January 1, 2018, the Company adopted ASU 2014-09 and all subsequent amendments (collectively “ASC 606”). The majority of the Company's revenue comes from interest income, including loans and securities, that are outside the scope of ASC 606. The Company's services that fall within the scope of ASC 606 are presented within noninterest income on the consolidated statements of income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of ASC 606 include service charges on deposit accounts, income from fiduciary investment management and brokerage activities and interchange fees from service charges on ATM and debit card transactions. ASC 606 did not result in a change to the accounting for any in-scope revenue streams; as such, no cumulative effect adjustment was recorded. ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. Our adoption of ASU 2016-01 on January 1, 2018, did not have a material effect on our consolidated financial condition or results of operations. In accordance with (iv) above, the Company measured fair value of its loan portfolio at September 30, 2018 using an exit price methodology as indicated in Note 10, Fair Value. ASU 2016-02, Leases (Topic 842). ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and 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. ASU 2016-02 will be effective for the Company on January 1, 2019. In July 2018, the FASB issued amendments in ASU 2018-11, which provide a transition election to not restate comparative periods for the effects of applying the new standard. The Company expects to elect this transition election, which permits entities to change the date of initial application to the beginning of the year of adoption and to recognize the effects of applying the new standard as a cumulative-effect adjustment to the opening balance of retained earnings. The Company anticipates that the impact on its consolidated balance sheet will result in an increase in assets and liabilities for its right of use assets and related lease liabilities for those leases that are outstanding at the date of adoption, however, it does not anticipate it will have a material impact on its results of operations. Management is evaluating other effects of this standard on our consolidated financial position and regulatory capital. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on our consolidated financial statements. In that regard, the Company has formed a cross-functional working group, under the direction of the Chief Financial Officer and the Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, finance and information technology. We are currently developing an implementation plan to include, but not limited to, an assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs. We have selected a third-party vendor solution to assist us in the application of ASU 2016-13. While the Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of the Company's loan and securities portfolios, as well as the prevailing economic conditions and forecasts, at the adoption date. ASU 2016-15, Statement of Cash Flows (Topic 230) - Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. On January 1, 2018, the Company adopted ASU 2016-18 with no material impact on our consolidated financial condition or results of operations. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies how all entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 will be effective for the Company on January 1, 2020, with earlier adoption permitted, and is not expected to have a material impact on the Company's consolidated financial statements. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20). ASU 2017-08 shortens the amortization period of certain callable debt securities held at a premium to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for the Company on January 1, 2019, with early adoption permitted. Management does not anticipate ASU 2017-08 will have a material impact on the Company's consolidated financial statements. ASU 2017-09, Compensation - Stock Compensation (Topic 718). ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. On January 1, 2018, the Company adopted ASU 2017-09 with no material impact on our consolidated financial condition or results of operations. In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement and should present a reconciliation of the beginning balance to the ending balance for each period for which a statement of comprehensive income is presented. The disclosure requirements amendment will be effective for the Company with its first interim reporting filing in 2019. The Company expects these changes will result in additional disclosures for the consolidated statement of changes in stockholders' equity and is evaluating any additional impact of these changes on its consolidated financial statements.
Revenue Recognition	All of the Company's revenue from contracts with customers within the scope of ASC 606 is recognized within noninterest income on the consolidated statements of income. Consistent with ASC 606, noninterest income covered by this guidance is recognized as services are transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those services. Service Charges on Deposit Accounts - The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Interchange Income - The Company earns interchange fees from debit/credit cardholder transactions conducted through the MasterCard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Interchange income is presented net of cardholder rewards. Wealth Management and Investment Advisory Income (Gross) - The Company earns wealth management and investment brokerage fees from its contracts with trust and wealth management customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Company provides the contracted services and are generally assessed based on a tiered scale of the market value of assets under management. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed, i.e., the trade date. Other related services provided included financial planning services and the fees the Company earns, which are based on a fixed fee schedule, are recognized when the services are rendered. Services are generally billed in arrears and a receivable is recorded until fees are paid. Investment Brokerage Income (Net) - The Company earns fees from investment management and brokerage services provided to its customers through a third-party service provider. The Company receives commissions from the third-party service provider and recognizes income on a weekly basis based upon customer activity. Because the Company acts as an agent in arranging the relationship between the customer and the third-party service provider and does not control the services rendered to the customers, investment brokerage income is presented net of related costs. Gains/Losses on Sales of OREO - The Company records a gain or loss on the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. If the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.
