Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies used by Enterprise Financial Services Corp (the "Company" or "Enterprise") in the preparation of the condensed consolidated financial statements are summarized below: Business and Consolidation Enterprise is a financial holding company that provides a full range of banking and wealth management services to individuals and corporate customers located in the St. Louis, Kansas City, and Phoenix metropolitan markets through its banking subsidiary, Enterprise Bank & Trust (the "Bank"). Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2018 . For further information, refer to the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 , as filed with the Securities and Exchange Commission. Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with the accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. During the first quarter of 2018, the Company adopted Accounting Standards Update ("ASU") 2016-01, "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 requires equity investments to be measured at fair value through earnings, and eliminates the available-for-sale classification for equity securities with readily determinable fair values. The guidance also provides an alternative to measure equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer (the “measurement alternative”). The Company elected the measurement alternative for its qualifying equity securities. The adoption of this update resulted in an insignificant increase to retained earnings which was reclassified from accumulated other comprehensive income. In addition, the Company early adopted ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" during the first quarter of 2018. The objective of ASU 2017-12 is to improve the financial reporting of hedging relationships by better aligning an entity's risk management activity with the economic objectives in undertaking those activities. The adoption of this update did not have a material effect on the Company's consolidated financial statements. The Company also early adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" during the first quarter of 2018. The ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017, which among other things, reduced the maximum federal corporate tax rate from 35% to 21%. The adoption of this update resulted in an increase to retained earnings of $0.8 million which was reclassified from accumulated other comprehensive income. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Revenue The Company adopted the accounting standard regarding revenue recognition in the first quarter of 2018 using the modified retrospective approach. The Company's revenues are primarily composed of interest income on financial instruments, including investment securities, which are excluded from the scope of the new guidance. Certain other noninterest income from loans, investment securities and derivative financial instruments is also excluded from this guidance. Service charges on deposit accounts, wealth management revenue, card services revenue, and gain on sale of other real estate are within the scope of the guidance; however, there were no accounting policy changes as the Company's policies were consistent with the new guidance. Other noninterest income sources of revenue are considered immaterial. Implementation of this guidance did not change current business practices or have any changes to the Company's consolidated financial statements. Descriptions of our revenue-generating activities within the scope of this guidance, which are presented in our income statement as components of noninterest income are as follows: • Service charges on deposit accounts - represents fees generated from a variety of deposit products and services provided to customers under a day-to-day contract. These fees are recognized on a daily or monthly basis. • Wealth management revenue - represents monthly fees earned from directing, holding, and managing customers’ assets. Revenue is recognized over regular intervals, either monthly or quarterly. • Card services revenue - represents revenue earned from merchant, debit and credit cards as incurred and includes a contra revenue account for rebates. • Gain on sale of other real estate - represents income recognized at delivery of control of a property at the time of a real estate closing. Income Taxes The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act of 2017 (“Tax Act”). SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The Company has recorded amounts for the effects of the Tax Act using reasonable estimates based on currently available information and its interpretations thereof. This accounting may change due to, among other things, changes in interpretations the Company has made and the issuance of new tax or accounting guidance. |

Earnings Per Share [Abstract] | |
Earnings Per Share | EARNINGS PER SHARE Basic earnings per common share data is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per common share gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method. The following table presents a summary of per common share data and amounts for the periods indicated. Three months ended Nine months ended (in thousands, except per share data) 2018 2017 2018 2017 Net income as reported $ 22,516 $ 16,315 $ 65,688 $ 40,661 Weighted average common shares outstanding 23,148 23,324 23,129 22,914 Additional dilutive common stock equivalents 181 250 211 295 Weighted average diluted common shares outstanding 23,329 23,574 23,340 23,209 Basic earnings per common share: $ 0.97 $ 0.70 $ 2.84 $ 1.77 Diluted earnings per common share: $ 0.97 $ 0.69 $ 2.81 $ 1.75 For the three and nine months ended September 30, 2018 and 2017 , there were no common stock equivalents excluded from the earnings per share calculations because their effect would have been anti-dilutive. |

The agency mortgage-backed securities are all issued by U.S. Government agencies and sponsored enterprises. Securities having a fair value of $365.3 million and $500.0 million at September 30, 2018 , and December 31, 2017 , respectively, were pledged as collateral to secure deposits of public institutions and for other purposes as required by law or contract provisions. The amortized cost and estimated fair value of debt securities at September 30, 2018 , by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted average life of the mortgage-backed securities is approximately 5 years.

Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2018 , management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired. |

Portfolio Loans | LOANS The loan portfolio is comprised of loans originated by the Company and loans acquired in connection with the Company’s acquisitions. These loans are accounted for using the guidance in the Accounting Standards Codification (ASC) section 310-30 and 310-20. Loans accounted for using ASC 310-30 are sometimes referred to as purchased credit impaired ("PCI") loans.

This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: • Grades 1 , 2 , and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has experience and depth within their industry. • Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and balance sheet condition, and sufficient liquidity and cash flow. • Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization, liquidity, and cash flow. • Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may be correctable in the near future. Alternatively, this rating category may also include circumstances where the borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7 , 8 , or 9 rating. • Grade 7 – Watch credits are borrowers that have experienced financial setback of a nature that is not determined to be severe or influence ‘ongoing concern’ expectations. Although possible, no loss is anticipated, due to strong collateral and/or guarantor support. • Grade 8 – Substandard credits include those borrowers characterized by significant losses and sustained downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted to secondary sources. Collateral exposure may exist and additional reserves may be warranted. • Grade 9 – Doubtful credits include borrowers that may show deteriorating trends that are unlikely to be corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off, or debt renegotiation with the borrower. The borrower may have declared bankruptcy or bankruptcy is likely in the near term. All doubtful rated credits will be on non-accrual.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments | COMMITMENTS AND CONTINGENCIES The Company issues financial instruments with off balance sheet risk in the normal course of the business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At September 30, 2018 , the amount of unadvanced commitments on impaired loans was insignificant. The contractual amounts of off-balance-sheet financial instruments as of September 30, 2018 , and December 31, 2017 , are as follows: (in thousands) September 30, 2018 December 31, 2017 Commitments to extend credit $ 1,315,284 $ 1,298,423 Letters of credit 49,633 73,790 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 usually have fixed expiration dates or other termination clauses, may have significant usage restrictions, and may require payment of a fee. Of the total commitments to extend credit at September 30, 2018 , and December 31, 2017 , approximately $91.8 million and $112.0 million , respectively, represent fixed rate loan commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, premises and equipment, and real estate. Other liabilities includes $0.4 million for estimated losses attributable to the unadvanced commitments at September 30, 2018 , and December 31, 2017 . Standby letters of credit are conditional commitments issued by the Company to guarantee the performance or payment of a customer to a third party. These standby letters of credit are issued to support contractual obligations of the Company’s customers. The credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers. As of September 30, 2018 , the approximate remaining terms of standby letters of credit range from 1 month to 3 years and 3 months . Contingencies The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Management believes there are no such proceedings pending or threatened against the Company or its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries. |

Fair Value Measurements | FAIR VALUE MEASUREMENTS Below is a description of certain assets and liabilities measured at fair value. The following table summarizes financial instruments measured at fair value on a recurring basis as of September 30, 2018 and December 31, 2017 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: September 30, 2018 (in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Assets Securities available for sale Obligations of U.S. Government-sponsored enterprises $ — $ 97,681 $ — $ 97,681 Obligations of states and political subdivisions — 30,533 — 30,533 Residential mortgage-backed securities — 532,347 — 532,347 U.S. Treasury bills — 9,767 — 9,767 Total securities available for sale $ — $ 670,328 $ — $ 670,328 Other investments 144 — — 144 State tax credits held for sale — — 171 171 Derivative financial instruments — 4,895 — 4,895 Total assets $ 144 $ 675,223 $ 171 $ 675,538 Liabilities Derivative financial instruments $ — $ 4,895 $ — $ 4,895 Total liabilities $ — $ 4,895 $ — $ 4,895 December 31, 2017 (in thousands) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Fair Value Assets Securities available for sale Obligations of U.S. Government-sponsored enterprises $ — $ 99,224 $ — $ 99,224 Obligations of states and political subdivisions — 34,642 — 34,642 Residential mortgage-backed securities — 507,516 — 507,516 Total securities available for sale $ — $ 641,382 $ — $ 641,382 State tax credits held for sale — — 400 400 Derivative financial instruments — 3,589 — 3,589 Total assets $ — $ 644,971 $ 400 $ 645,371 Liabilities Derivative financial instruments $ — $ 3,589 $ — $ 3,589 Total liabilities $ — $ 3,589 $ — $ 3,589 • Securities available for sale . Securities classified as available for sale are reported at fair value utilizing Level 2 and Level 3 inputs. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions at the security level. • Other investments. At September 30, 2018 , of the $37.9 million of other investments on the condensed consolidated balance sheet, approximately $0.2 million were carried at fair value. The remaining $37.7 million of other investments were accounted for at cost. Other investments reported at fair value represent equity securities with quoted market prices (Level 1). • State tax credits held for sale. At September 30, 2018 , of the $45.6 million of state tax credits held for sale on the condensed consolidated balance sheet, approximately $0.1 million were carried at fair value. The remaining $45.5 million of state tax credits were accounted for at cost. The Company is not aware of an active market that exists for the 10 -year streams of state tax credit financial instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents who buy these credits and local and regional accounting firms who broker them. As such, the Company employed a discounted cash flow analysis (income approach) to determine fair value. The remaining state tax credits carried at fair value are expected to be sold within the next several quarters. The state tax credit assets are reported as Level 3 assets. • Derivatives . Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty quotations to value its interest rate swaps. In addition, the Company validates the counterparty quotations with third party valuation sources. Derivatives with negative fair values are included in Other liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets in the consolidated balance sheets. There were no transfers between Level 1 and Level 2 during the three and nine months ended September 30, 2018 and 2017. Level 3 financial instruments The following table presents the changes in Level 3 financial instruments measured at fair value on a recurring basis as of September 30, 2018 and 2017 .

These include assets measured at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring basis as of September 30, 2018 .

Impaired loans are reported at the fair value of the underlying collateral for collateral dependent loans. Fair values for impaired loans are obtained from current appraisals by qualified licensed appraisers or independent valuation specialists. At September 30, 2018, impaired loans measured on a non-recurring basis had a principal balance of $0.7 million , with a valuation allowance of $0.2 million . Other real estate owned is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Following is a summary of the carrying amounts and fair values of the Company’s financial instruments on the consolidated balance sheets at September 30, 2018 and December 31, 2017 .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
New Authoritative Accounting Guidance | NEW AUTHORITATIVE ACCOUNTING GUIDANCE Financial Accounting Standards Board (the "FASB") ASU 2018-15 "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement" In August 2018, the FASB issued ASU 2018-15, which amends ASC 350-402 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement (CCA) that is a service contract. ASU 2018-15 aligns the accounting for costs incurred to implement a CCA that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of a CCA that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA that is considered a service contract. The amendments are effective for public business entities for annual periods beginning after December 15, 2019, including interim periods within those annual periods, with early adoption being permitted. The Company is currently evaluating the new guidance and has not yet determined the impact this standard may have on its consolidated balance sheets. FASB ASU 2018-13 "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement" In August 2018, the FASB issued ASU 2018-13, which changes the fair value measurement disclosure requirements of ASC 820. The amendments in this ASU are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting — Chapter 8: Notes to Financial Statements, which the Board finalized on August 28, 2018. The Board used the guidance in the Concepts Statement, including consideration of costs and benefits, to improve the effectiveness of ASC 820’s disclosure requirements. The Company is currently evaluating the new guidance and has not yet determined the impact this standard may have on its consolidated balance sheets. FASB ASU 2018-11 "Leases (Topic 842): Targeted Improvements" In July 2018, the FASB issued ASU 2018-11 to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU 2016-02 (codified as ASC 842). Specifically, under the amendments in ASU 2018-11 (1)entities may elect not to recast the comparative periods presented when transitioning to ASC 842 (2) lessors may elect not to separate lease and nonlease components when certain conditions are met. The Company intends to utilize the optional transition method and apply the new leases standard at the adoption date of January 1, 2019. The Company is evaluating the impact of separating lease and nonlease components on its financial statements. FASB ASU 2017-08 "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities" In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20)" which shortens the amortization period of certain callable debt securities held at a premium to the earliest call date. The amendments are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption being permitted. The Company has evaluated the new guidance and does not expect it to have a material impact on the Company's consolidated financial statements. At September 30, 2018, the book value of callable bonds purchased at a premium totaled $22.0 million, and the amount of unamortized premium remaining on these securities was $0.7 million. FASB ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" In June 2016, the FASB issued ASU 2016-13, "Financial Instruments (Topic 326)" which changes the methodology for evaluating impairment of most financial instruments. The ASU replaces the currently used incurred loss model with a forward-looking expected loss model, which will generally result in a more timely recognition of losses. The guidance becomes effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has formed an implementation team that includes members of accounting, credit, and loan operations to review the requirements of ASU 2016-13, and has contracted with a software provider to aid in implementation. The Company has not yet determined the impact this standard may have on its financial statements. FASB ASU 2016-02 "Leases (Topic 842)" In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" which requires organizations that lease assets ("lessees") to recognize the assets and liabilities for the rights and obligations created by leases with terms of more than 12 months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee remains dependent on its classification as a finance or operating lease. The criteria for determining whether a lease is a finance or operating lease has not been significantly changed by this ASU. The ASU also requires additional disclosure of the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The guidance becomes effective for periods beginning after December 15, 2018, including interim periods therein. Early adoption will be permitted. The Company has formed a lease implementation team that includes members of accounting, facilities and operations to review lease contracts and the requirements of ASU 2016-02. The Company is currently evaluating the impact of this amendment on its financial statements; however, it does not expect the adoption of the new standard to have a material impact on its results of operations or balance sheet as a result of the recognition of right-to-use assets and lease liabilities related to operating leases. |
Summary of Significant Accoun_2
Summary of Significant Accounting Policies (Policies) | 9 Months Ended |
Sep. 30, 2018 | |
Accounting Policies [Abstract] | |
Business and Consolidation | Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with the accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. During the first quarter of 2018, the Company adopted Accounting Standards Update ("ASU") 2016-01, "Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 requires equity investments to be measured at fair value through earnings, and eliminates the available-for-sale classification for equity securities with readily determinable fair values. The guidance also provides an alternative to measure equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer (the “measurement alternative”). The Company elected the measurement alternative for its qualifying equity securities. The adoption of this update resulted in an insignificant increase to retained earnings which was reclassified from accumulated other comprehensive income. In addition, the Company early adopted ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" during the first quarter of 2018. The objective of ASU 2017-12 is to improve the financial reporting of hedging relationships by better aligning an entity's risk management activity with the economic objectives in undertaking those activities. The adoption of this update did not have a material effect on the Company's consolidated financial statements. The Company also early adopted ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" during the first quarter of 2018. The ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017, which among other things, reduced the maximum federal corporate tax rate from 35% to 21%. The adoption of this update resulted in an increase to retained earnings of $0.8 million which was reclassified from accumulated other comprehensive income. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Revenue The Company adopted the accounting standard regarding revenue recognition in the first quarter of 2018 using the modified retrospective approach. The Company's revenues are primarily composed of interest income on financial instruments, including investment securities, which are excluded from the scope of the new guidance. Certain other noninterest income from loans, investment securities and derivative financial instruments is also excluded from this guidance. Service charges on deposit accounts, wealth management revenue, card services revenue, and gain on sale of other real estate are within the scope of the guidance; however, there were no accounting policy changes as the Company's policies were consistent with the new guidance. Other noninterest income sources of revenue are considered immaterial. Implementation of this guidance did not change current business practices or have any changes to the Company's consolidated financial statements. Descriptions of our revenue-generating activities within the scope of this guidance, which are presented in our income statement as components of noninterest income are as follows: • Service charges on deposit accounts - represents fees generated from a variety of deposit products and services provided to customers under a day-to-day contract. These fees are recognized on a daily or monthly basis. • Wealth management revenue - represents monthly fees earned from directing, holding, and managing customers’ assets. Revenue is recognized over regular intervals, either monthly or quarterly. • Card services revenue - represents revenue earned from merchant, debit and credit cards as incurred and includes a contra revenue account for rebates. • Gain on sale of other real estate - represents income recognized at delivery of control of a property at the time of a real estate closing. Income Taxes The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act of 2017 (“Tax Act”). SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The Company has recorded amounts for the effects of the Tax Act using reasonable estimates based on currently available information and its interpretations thereof. This accounting may change due to, among other things, changes in interpretations the Company has made and the issuance of new tax or accounting guidance. |
Available-for-sale Securities | Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2018 , management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired. |
