SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company and the Bank follow accounting principles generally accepted in the United States of America including, where applicable, general practices within the banking industry. 1. Principles of Consolidation The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany accounts and transactions have been eliminated. 2. Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, acquisition accounting, intangible assets, and deferred tax assets. 3. Cash and Due From Banks Included in cash and due from banks are legal reserve requirements which must be maintained on an average basis in the form of cash and balances due from the Federal Reserve. The reserve balance varies depending upon the types and amounts of deposits. At December 31, 2018, the required reserve balance on deposit with the Federal Reserve Bank was approximately $30.9 million. 4. Debt Securities Investments in securities are accounted for as follows: Available-for-Sale Securities Securities classified as available-for-sale are those securities that are intended to be held for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including movements in interest rates, liquidity needs, security risk assessments, changes in the mix of assets and liabilities and other similar factors. These securities are carried at their estimated fair value, and the net unrealized gain or loss is reported net of tax, as component of accumulated other comprehensive income (loss) in stockholders’ equity, until realized. Premiums and discounts are recognized in interest income using the interest method. Gains and losses on the sale of available-for-sale securities are determined using the adjusted cost of the specific security sold. Securities to be Held-to-Maturity Securities classified as held-to-maturity are those securities for which there is a positive intent and ability to hold to maturity. These securities are carried at cost adjusted for amortization of premiums and accretion of discounts, computed by the interest method. Trading Account Securities Trading account securities are those securities which are held for the purpose of selling them at a profit. There were no trading account securities on hand at December 31, 2018, 2017 and 2016. Equity Securities Equity securities are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Other Securities Other securities are carried at cost and are restricted in marketability. Other securities consist of investments in the Federal Home Loan Bank (FHLB), Federal Reserve Bank and First National Bankers’ Bankshares, Inc. Management reviews for impairment based on the ultimate recoverability of the cost basis. Shares of Federal Home Loan Bank (FHLB), Federal Reserve Bank and First National Bankers’ Bankshares, Inc. common stock are equity securities that do not have a readily determinable fair value because their ownership is restricted and lacks marketability. The common stock is carried at cost and evaluated for impairment. The Company’s investment in member bank stock is included in other securities in the accompanying consolidated balance sheets. Management reviews for impairment based on the ultimate recoverability of the cost basis. No other-than-temporary impairment was noted for the years ended December 31, 2018, 2017 and 2016. Interest Income Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. On January 1, 2018, the Company adopted the new accounting standard for Financial Instruments, which requires investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with the changes in fair value recognized in net income. The adoption of this guidance resulted in a $348 thousand decrease to retained earnings. Other-than-Temporary Impairment (“OTTI”) Management evaluates investment securities for other-than-temporary impairment on 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 as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) other-than-temporary impairment (OTTI) related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. 5. Loans held for sale The Bank originates fixed rate single family, residential first mortgage loans on a presold basis. The Bank issues a rate lock commitment to a customer and concurrently “locks in” with a secondary market investor under a best efforts delivery mechanism. Such loans are sold without the mortgage servicing rights being retained by the Bank. The terms of the loan are dictated by the secondary investors and are transferred within several weeks of the Bank initially funding the loan. The Bank recognizes certain origination fees and service release fees upon the sale, which are included in other income on loans in the consolidated statements of income. Between the initial funding of the loans by the Bank and the subsequent purchase by the investor, the Bank carries the loans held for sale at the lower of cost or fair value in the aggregate as determined by the outstanding commitments from investors. 6. Loans Loans are carried at the principal amount outstanding, net of the allowance for loan losses. Interest income on loans is recognized based on the principal balance outstanding and the stated rate of the loan. Loan origination fees and certain direct origination costs are deferred and recognized as an adjustment of the related loan yield using the interest method. A loan is considered impaired, in accordance with the impairment accounting guidance of Accounting Standards Codification (ASC) Section 310-10-35, Receivables, Subsequent Measurement , when, based upon current events and information, it is probable that the scheduled payments of principal and interest will not be collected in accordance with the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral values, and the probability of collecting scheduled payments of principal and interest when due. Generally, impairment is measured on a loan by loan basis using the fair value of the supporting collateral. Loans are generally placed on a non-accrual status, and the accrual of interest on such loan is discontinued, when principal or interest is past due ninety days or when specifically determined to be impaired unless the loan is well-secured and in the process of collection. When a loan is placed on non-accrual status, interest accrued but not received is generally reversed against interest income. If collectability is in doubt, cash receipts on non-accrual loans are used to reduce principal rather than recorded in interest income. Past due status is determined based upon contractual terms. Loans are returned to accrual status when the obligation is brought current or has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt. 7. Allowance for Loan Losses The allowance for loan losses is a valuation allowance reserved for probable incurred credit losses. A charge is taken against the allowance for loan losses when management believes the collectibility of the loan principal is confirmed to be unlikely. Subsequent recoveries, if any, are credited back to the allowance. Management evaluates the adequacy of the allowance for loan losses on a regular basis. These evaluations are based upon a periodic review of the historical loan loss experience, the nature and value of the loan portfolio, underlying collateral values, internal and independent loan reviews, and prevailing economic conditions. In addition, the OCC, as a part of the regulatory examination process, reviews the loan portfolio and the allowance for loan losses and may require changes in the allowance based upon information available at the time of the examination. The allowance consists of two components, a reserve for general pool (or formula pool) loans that are collectively evaluated for impairment, and a reserve for loans individually evaluated for impairment based on expected loan specific losses. These components represent an estimation performed pursuant to either ASC Topic 450, Contingencies Receivables The Bank also has acquired loan portfolios accounted for under the acquisition method of accounting. Within these portfolios are purchased credit impaired loans accounted for under ASC Topic 310-30. Impairment may be determined specifically at an individual loan level, or estimated on various pools of loans having common risk characteristics. 8. Purchased Credit Impaired Loans (“PCI”) The Company purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as credit score, loan type, and date of origination. The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. 9. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. The depreciation policy is to provide for depreciation over the estimated useful lives of the assets using the straight-line method. Repairs and maintenance expenditures are charged to operating expenses; major expenditures for renewals and betterments are capitalized and depreciated over their estimated useful lives. Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts, and any gains or losses are included in operations. Building and related components are depreciated using the straight-line method with useful lives ranging from 10 to 39 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years. 10. Other Real Estate Owned Other real estate owned consists of properties acquired through foreclosure and, as held for sale $10.9 million and $7.2 million, respectively. 11. Goodwill and Other Intangible Assets Goodwill totaled $89.8 million and $20.0 million for the years ended December 31, 2018, and 2017, respectively. Goodwill totaling $69.8 million was recorded during the year ended December 31, 2018, as a result of the acquisitions of First Community Bank, Sunshine Community Bank and Famers and Merchants Bank. See Note C – Business Combinations to these consolidated financial statements for additional information on the acquisitions during 2018. The Company performed the required annual impairment tests of goodwill and other intangibles as of December 1, 2018. The Company’s annual impairment test did not indicate impairment as of the testing date, and subsequent to that date, management is not aware of any events or changes in circumstances since the impairment test that would indicate that goodwill or other intangibles might be impaired. The Company’s acquisition method recognized intangible assets, which are subject to amortization, and included in other assets in the accompanying consolidated balance sheets, are core deposit intangibles, amortized on a straight-line basis, over a 10 year average life. The definite-lived intangible assets had the following carrying values at December 31, 2018 and 2017: 2018 ($ in thousands) Gross Carrying Amount Accumulated Amortization Net Carrying Amount Core deposit intangibles $ 27,752 $ (4,586 ) $ 23,166 2017 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Core deposit intangibles $ 7,640 $ (2,930 ) $ 4,710 The related amortization expense of business combination related intangible assets is as follows: ($ in thousands) Amount Aggregate amortization expense for the year ended December 31: 2016 $ 383 2017 664 2018 1,656 Amount Estimated amortization expense for the year ending December 31: 2019 $ 2,706 2020 2,706 2021 2,636 2022 2,466 2023 2,420 Thereafter 10,232 $ 23,166 12. Other Assets and Cash Surrender Value The Company invests in bank owned life insurance (BOLI). BOLI involves the purchase of life insurance by the Company on a chosen group of employees. The Company is the owner of the policies and, accordingly, the cash surrender value of the policies is reported as an asset, and increases in cash surrender values are reported as income. 13. Other Liabilities Financing costs related to the issuance of junior subordinated debentures are being amortized over the life of the instruments and are included in other liabilities. 14. Restricted Stock The Company accounts for stock based compensation in accordance with ASC Topic 718, Compensation - Stock Compensation 15. Income Taxes The Company and its subsidiary file consolidated income tax returns. The subsidiary provides for income taxes on a separate return basis and remits to the Company amounts determined to be payable. Income taxes are provided for the tax effects of the transactions reported in the financial statements and consist of taxes currently payable plus deferred taxes related primarily to differences between the bases of assets and liabilities as measured by income tax laws and their bases as reported in the financial statements. The deferred tax assets and liabilities represent the future tax consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. ASC Topic 740, Income Taxes, 16. Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense for the years ended December 31, 2018, 2017 and 2016, was $382 thousand, $336 thousand, and $402 thousand, respectively. 17. Statements of Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash, amounts due from banks, interest-bearing deposits with banks and federal funds sold. Generally, federal funds are sold for a one to seven day period. 18. Off-Balance Sheet Financial Instruments In the ordinary course of business, the subsidiary bank enters into off-balance sheet financial instruments consisting of commitments to extend credit, credit card lines and standby letters of credit. Such financial instruments are recorded in the financial statements when they are exercised. 19. Earnings Applicable to Common Stockholders Per share amounts are presented in accordance with ASC Topic 260, Earnings Per Share. Under ASC Topic 260, two per share amounts are considered and presented, if applicable. Basic per share data is calculated based on the weighted-average number of common shares outstanding during the reporting period. Diluted per share data includes any dilution from securities that may be converted into common stock, such as outstanding restricted stock. The following tables disclose the reconciliation of the numerators and denominators of the basic and diluted computations applicable to common stockholders ($ in thousands, except per share amount): For the Year Ended December 31, 2018 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common Share $ 21,225 12,986 $ 1.63 Effect of dilutive shares: Restricted Stock 108 $ 21,225 13,094 $ 1.62 For the Year Ended December 31, 2017 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common Share $ 10,616 9,484 $ 1.12 Effect of dilutive shares: Restricted Stock 77 $ 10,616 9,561 $ 1.11 For the Year Ended December 31, 2016 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common share $ 9,666 5,435 $ 1.78 Convertible Preferred dividend 134 Effect of dilutive shares: Convertible Preferred , Series E 742 Restricted Stock 82 $ 9,800 6,259 $ 1.57 The diluted per share amounts were computed by applying the treasury stock method. 20. Mergers and Acquisitions Business combinations are accounted for under ASC 805, “ Business Combinations ”, using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversion, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the non-interest expense caption. 21. Investment in Limited Partnership The Company invested $ 4.4 $3.4 million at December 31, 2018 and $3.8 million at December 31, 2017, net of amortization, using the proportional method and is reported in other assets on the Consolidated Balance Sheets. The Company’s maximum exposure to loss is limited to the carrying value of its investment. The Company received $481 thousand in low-income housing tax credits during 2018, $481 thousand in 2017 and $160 thousand in 2016. 22. Reclassifications Certain reclassifications have been made to the 2017 and 2016 financial statements to conform with the classifications used in 2018. These reclassifications did not impact the Company's consolidated financial condition or results of operations. 23. Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-11 eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect for early adoption the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. The revised disclosure requirements will not have a material impact on the Company’s Consolidated Financial Statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 has been issued as part of a simplification initiative which will expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees and expands the scope through the amendments to address and improve aspects of the accounting for non-employee share-based payment transactions. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018. The Company is currently evaluating the provisions of ASU 2018-07 to determine the potential impact the new standard will have on its Consolidated Financial Statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. In February, 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . ASU No. 2018-02 allows for the reclassification from other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the Act). ASU 2018-02 also allows an accounting policy election to reclassify other stranded tax effects that relate to the Act but are not directly related to the change in federal tax rate. ASU 2018-02 is effective in the first quarter of 2019. Early adoption is permitted for reporting periods for which financial statements have not yet been issued. The Company adopted ASU 2018-02 in the fourth quarter of 2017 by retrospective application. Upon adoption, the Company made a policy election to reclassify stranded tax effects of approximately $76 thousand from Accumulated Other Comprehensive Income to retained earnings using the specific identification method. In May 2017, the FASB issued ASU No. 2017-09, “ Stock Compensation, Scope of Modification Accounting.” In March 2017, the FASB issued ASU No. 2017-08, “ Premium Amortization on Purchased Callable Debt Securities.” In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for any impairment tests performed after January 1, 2017. The Company is currently assessing the impact of ASU 2017-04 on its Consolidated Financial Statements. In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 included specific guidance on how to classify certain transactions in the statement of cash flows and reduced diversity in practice in how eight particular transactions are classified in the statement of cash flows. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Entities were required to apply the guidance retrospectively unless it would have been impracticable to do, in which case the amendments could have been applied prospectively. The Company applied the guidance retrospectively. As this guidance only affects the classification within the statement of cash flows, ASU 2016-15 did not have a material impact on the Company's Consolidated Financial Statements. In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” . ASU 2016-13 requires a new impairment model known as the current expected credit loss (“CECL”) which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. The main provisions of ASU 2016-13 include (1) replacing the “incurred loss” approach under current GAAP with an “expected loss” model for instruments measured at amortized cost, (2) requiring entities to record an allowance for credit losses related to available-for-sale debt securities rather than a direct write-down of the carrying amount of the investments, as is required by the other-than-temporary-impairment model under current GAAP, and (3) a simplified accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted. The Company is currently working with a third party to assess the impact of the adoption of ASU 2016-13 on its Consolidated Financial Statements. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption could be influenced by the composition, characteristics and quality of our loan portfolio as well as the prevailing economic conditions and forecasts as of the adoption date. As part of our implementation process, we have established a working group that includes individuals from various functional areas that made initial assessments regarding portfolio segmentation, reviewed system requirements, engaged a third party software vendor, and have begun to model expected loss estimates. In February 2016, the FASB issued ASU No. 2016-02 “ Leases (Topic 842).” ASU 2016-02 establishes a right of use model that requires a lessee to record a right of use asset and a lease liability for all leases with terms longer than 12 months. Leases will be classified as either finance or operating with classification affecting the pattern of expense recognition in the income statement. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If neither risks and rewards nor control is conveyed, an operating lease results. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with certain practical expedients available. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Leases – Targeted Improvements. ASU 2018-11 provides entities with relief from the costs of implementing certain aspects of ASU 2016-02. Under the amendments in ASU 2018-11 entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard and lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02, January 1, 2019. We have elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. Our operating leases relate primarily to bank branches. Based on our lease portfolio as of December 31, 2018, we anticipate recognizing a lease liability on our balance sheet of approximately $1.8 million with an offsetting right-of-use asset. In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606)”

Business Combination, Description [Abstract]
BUSINESS COMBINATIONS	NOTE C – BUSINESS COMBINATIONS The Company accounts for its business combinations using the acquisition method. Acquisition accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the acquisition method. Core deposit intangibles and other identified intangibles with finite useful lives are amortized using the straight-line method over their estimated useful lives of up to ten years. Loans that the Company acquires in connection with acquisitions are recorded at fair value with no carryover of the related allowance for credit losses. Fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The excess or deficit of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount or amortizable premium and is recognized into interest income over the remaining life of the loan. Acquisitions FMB Financial Corp. On November 1, 2018, the Company completed its acquisition of FMB Banking Corporation (“FMB), and immediately thereafter merged its wholly-owned subsidiary, Farmers & Merchants Bank, with and into The First.

REGULATORY MATTERS

REGULATORY MATTERS	12 Months Ended
	Dec. 31, 2018
Banking and Thrift [Abstract]
REGULATORY MATTERS	NOTE J - REGULATORY MATTERS The Company and its subsidiary bank are subject to regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its subsidiary bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgment by regulators about components, risk weightings, and other related factors. To ensure capital adequacy, quantitative measures have been established by regulators, and these require the Company and its subsidiary bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined) to risk-weighted assets (as defined), Tier 1 capital to adjusted total assets (leverage) and common equity Tier 1. Management believes, as of December 31, 2018, that the Company and its subsidiary bank exceeded all capital adequacy requirements. In 2013, the Federal Reserve voted to adopt final capital rules implementing Basel III requirements for U.S. Banking organizations. Under the final rule, minimum requirements increased for both the quantity and quality of capital held by banking organizations. The final rule includes a new minimum ratio of common equity Tier 1 capital (Tier 1 Common) to risk-weighted assets and a Tier 1 Common capital conservation buffer of 2.5% of risk-weighted assets that will apply to all supervised financial institutions. The rule also raises the minimum ratio of Tier 1 capital to risk-weighted assets and includes a minimum leverage ratio of 4% for all banking organizations. These new minimum capital ratios were effective on January 1, 2015, At December 31, 2018 and 2017, the subsidiary bank was categorized by regulators as well-capitalized under the regulatory framework for prompt corrective action. Under Basel III requirements, a financial institution is considered to be well-capitalized if it has a total risk-based capital ratio of 10% or more, has a Tier 1 risk-based capital ratio of 8% or more, has a common equity Tier 1 of 6.5%, and has a Tier 1 leverage capital ratio of 5% or more. There are no conditions or anticipated events that, in the opinion of management, would change the categorization.

Consequently, dividends are dependent upon The First’s earnings, capital needs, regulatory policies, as well as statutory and regulatory limitations. Federal and state banking laws and regulations restrict the amount of dividends and loans a bank may make to its parent company. Approval by the Company’s regulators is required if the total of all dividends declared in any calendar year exceed the total of its net income for that year combined with its retained net income of the preceding two years. In 2018, the Company had available $30.7 million to pay dividends.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. The credit policies and procedures for such commitments are the same as those used for lending activities. Because these instruments have fixed maturity dates and because a number expire without being drawn upon, they generally do not present any significant liquidity risk. No significant losses on commitments were incurred during the two years ended December 31, 2018, nor are any significant losses as a result of these transactions anticipated. The contractual amounts of financial instruments with off-balance-sheet risk at year-end were as follows: ($ in thousands) 2018 2017 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 32.6 $ 36.8 $ 26.7 $ 30.2 Unused lines of credit 115.5 131.7 104.9 119.6 Standby letters of credit 2.3 8.4 1.8 6.4 Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 18% to 3.25% and maturities ranging from 1 year to 30 years. The primary market areas served by the Bank are Forrest, Lamar, Jones, Pearl River, Jackson, Hancock, Stone, Harrison Counties within South Mississippi, Madison and Rankin Counties in Central Mississippi, as well as Washington Parish, St. Tammany Parish, Plaquemine Parish, Livingston Parish, West Baton Rouge Parish, East Baton Rouge Parish, Iberville Parish, Assumption Parish and Ascension Parish in Louisiana, Washington, Baldwin and Mobile Counties in South Alabama, Escambia County in Northwestern Florida, Santa Rosa County, Jefferson County, Leon County in Florida, and Thomasville County in Georgia. Management closely monitors its credit concentrations and attempts to diversify the portfolio within its primary market area. As of December 31, 2018, management does not consider there to be any significant credit concentrations within the loan portfolio. Although the Bank’s loan portfolio, as well as existing commitments, reflects the diversity of its primary market area, a substantial portion of a borrower's ability to repay a loan is dependent upon the economic stability of the area. In the normal course of business, the Company and its subsidiary are subject to pending and threatened legal actions. Although the Company is not able to predict the outcome of such actions, after reviewing pending and threatened actions with counsel, management believes that based on the information currently available the outcome of such actions, individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUES OF ASSETS AND LIABILITIES	NOTE R - FAIR VALUES OF ASSETS AND LIABILITIES The Company follows the guidance of ASC Topic 820, Fair Value Measurements and Disclosures, that establishes a framework for measuring fair value and expands disclosures about fair value measurements. The guidance defines the fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In accordance with the guidance, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1: Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2: Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities which use observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets and liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets. Securities The fair value of available-for-sale securities is determined by various valuation methodologies. Where quoted market prices are available in an active market, securities are classified within Level 1. If quoted market prices are not available, then fair values are estimated by using pricing models or quoted prices of securities with similar characteristics. Level 2 securities include U.S. Treasury securities, obligations of U.S. government corporations and agencies, obligations of states and political subdivisions, mortgage-backed securities and collateralized mortgage obligations. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the The following table presents the Company’s securities that are measured at fair value on a recurring basis and the level within the hierarchy in which the fair value measurements fell as of December 31, 2018 and 2017 ($ in thousands): Fair Value Measurements Using Quoted Prices in Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs December 31, 2018 Fair Value (Level 1) (Level 2) (Level 3) Available-for-sale Obligations of U.S. Government agencies and sponsored entities $ 47,342 $ - $ 47,342 $ - Municipal securities 150,064 - - 150,064 Mortgage-backed securities 287,470 - 287,470 - Corporate obligations 7,348 - 6,474 874 Total available for sale $ 492,224 $ - $ 341,286 $ 150,938 Fair Value Measurements Using Quoted Prices in Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs December 31, 2017 Fair Value (Level 1) (Level 2) (Level 3) Available-for-sale Obligations of U.S. Government agencies and sponsored entities $ 4,992 $ - $ 4,992 $ - Municipal securities 138,584 - 138,584 - Mortgage-backed securities 196,578 - 196,578 - Corporate obligations 15,819 - 13,250 2,569 Total available for sale $ 355,973 $ - $ 353,404 $ 2,569 Other $ 920 $ 920 $ - $ - The following is a reconciliation of activity for assets measured at fair value based on significant unobservable (non-market) information.

Impaired Loans Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income date available for similar loans and collateral underlying such loans. Such adjustments, if any, result in a Level 3 classification of the inputs for determining fair value. The Company adjust the appraisal 10 percent. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment. Other Real Estate Owned Other real estate owned consists of properties obtained through foreclosure. The adjustment at the time of foreclosure is recorded through the allowance for loan losses. Fair value of other real estate owned is based on current independent appraisals of the collateral less costs to sell when acquired, establishing a new costs basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals, which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments, if any, result in a Level 3 classification of the inputs for determining fair value. In the determination of fair value subsequent to foreclosure, Management also considers other factors or recent developments, such as changes in market conditions from the time of valuation and anticipated sales values considering plans for disposition, which could result in an adjustment to lower the collateral value estimates indicated in the appraisals. The Company adjust the appraisal 10 percent. Periodic revaluations are classified as Level 3 in the fair value hierarchy since assumptions are used that may not be observable in the market. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined the fair value declines subsequent to foreclosure, a valuation allowance is recorded through other income. Operating costs associated with the assets after acquisition are also recorded as non-interest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and recorded in other income. Other real estate measured at fair value on a non-recurring basis at December 31, 2018, amounted to $10.9 million. Other real estate owned is classified within Level 3 of the fair value hierarchy. The following table presents the fair value measurement of assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements were reported at December 31, 2018 and 2017. ($ in thousands) Fair Value Measurements Using Quoted Prices in Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Fair Value (Level 1) (Level 2) (Level 3) December 31, 2018 Impaired loans (1) $ 28,928 $ - $ - $ 28,928 Other real estate owned 10,869 - - 10,869 December 31, 2017 Impaired loans $ 9,614 $ - $ - $ 9,614 Other real estate owned 7,158 - - 7,158 (1) Impaired loans include $17,652 in PCI loans. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value: Cash and Cash Equivalents – For such short-term instruments, the carrying amount is a reasonable estimate of fair value. Investment in securities available-for-sale and held-to-maturity – The fair value measurement for securities available-for-sale was discussed earlier. The same measurement approach was used for securities held-to-maturity and other securities. Loans Fair Value Measurement Bank-owned Life Insurance – The fair value of bank-owned life insurance approximates the carrying amount, because upon liquidation of these investments, the Company would receive the cash surrender value which equals the carrying amount. Accrued Interest Receivable – The carrying amount of accrued interest receivable approximates fair value and is classified as level 2 for accrued interest receivable related to investments securities and Level 3 for accrued interest receivable related to loans. Deposits – The fair values of demand deposits are, as required by ASC Topic 825, equal to the carrying value of such deposits. Demand deposits include non-interest-bearing demand deposits, savings accounts, NOW accounts, and money market demand accounts. The fair value of variable rate term deposits, those repricing within six months or less, approximates the carrying value of these deposits. Discounted cash flows have been used to value fixed rate term deposits and variable rate term deposits repricing after six months. The discount rate used is based on interest rates currently being offered on comparable deposits as to amount and term. Short-Term Borrowings – The carrying value of any federal funds purchased and other short-term borrowings approximates their fair values. FHLB and Other Borrowings – The fair value of the fixed rate borrowings are estimated using discounted cash flows, based on current incremental borrowing rates for similar types of borrowing arrangements. The carrying amount of any variable rate borrowing approximates its fair value. Subordinated Debentures – Fair values are determined based on the current market value of like instruments of a similar maturity and structure. Accrued Interest Payable – The carrying amount of accrued interest payable approximates fair value resulting in a Level 2 classification. Off-Balance Sheet Instruments – Fair values of off-balance sheet financial instruments are based on fees charged to enter into similar agreements. However, commitments to extend credit do not represent a significant value until such commitments are funded or closed. Management has determined that these instruments do not have a distinguishable fair value and no fair value has been assigned.

SENIOR PREFERRED STOCK	NOTE S - PREFERRED STOCK Pursuant to the terms of a letter agreement between the Company and the United States Department of the Treasury (“Treasury”), the Company issued 17,123 CDCI Preferred Shares. The Letter Agreement contains limitations on the payment of dividends on the common stock to no more than 100% of the aggregate per share dividend and distributions for the immediate prior fiscal year (dividends were declared and paid in 2011 through 2016) and on the Company’s ability to repurchase its common stock in the event of a non-payment of our dividend, and continues to subject the Company to certain of the executive compensation limitations included in the Emergency Economic Stabilization Act of 2008 (EESA), as previously disclosed by the Company. The CDCI Preferred Shares entitle the holder to an annual dividend of 2% for 8 years of the liquidation value of the shares, payable quarterly in arrears. On May 13, 2015, The First Bancshares, Inc. (the “Company”) entered into a Letter Agreement (the “Letter Agreement”), with the United States Department of the Treasury (“Treasury”), pursuant to which the Company redeemed the Warrant to purchase up to 54,705 shares of the Company’s common stock, no par value per share (the “Common Stock”) issued to Treasury on February 6, 2009 under the Capital Purchase Program. In connection with this redemption, on May 13, 2015, the Company paid Treasury an aggregate redemption price of $302,410. On October 14, 2016, the Company issued 3,563,380 shares of Series E Convertible Preferred Stock at $17.75 per share in a private placement offering and received approximately $59,744,000 in net proceeds after offering expenses of $3,506,000. The net proceeds from this private placement were used to finance the Iberville Bank acquisition and pay related expenses, to support our capital ratios in connection with the Iberville Bank acquisition and Gulf Coast Community Bank acquisition, and for general corporate purposes. All 3,563,380 shares of the Series E Convertible Preferred Stock were converted into 3,563,380 shares of common stock on January 4, 2017, following shareholder approval. Dividends were declared and paid on the Series E Convertible Preferred Stock. On December 6, 2016, the Company repurchased all 17,123 shares of its CDCI Preferred Shares at fair market value of $15,925,000, which equated to a discount of 7% to par, or $1,198,000.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	NOTE T - REVENUE FROM CONTRACTS WITH CUSTOMERS On January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers. 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. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract; (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company concluded that there was no change to the timing and pattern of revenue recognition for its current revenue streams or the presentation of revenue as gross versus net. No adjustment to retained earnings was required on the adoption date. Because there was no change to the timing and pattern of revenue recognition, there were no material changes to the Company’s processes and internal controls. All of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized within noninterest income. The guidance does not apply to revenue associated with financial instruments, including loans and investment securities that are accounted for under other GAAP, which comprise a significant portion of our revenue stream. A description of the Company’s revenue streams accounted for under ASC 606 is as follows: Service Charges on Deposit Accounts Interchange Income Gains/Losses on Sales of OREO All of the Company’s revenue from contracts with customers in the scope of ASC 606 is recognized within non-interest income.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles of Consolidation	1. Principles of Consolidation The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany accounts and transactions have been eliminated.
Estimates	2. Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, acquisition accounting, intangible assets, and deferred tax assets.
Cash and Due From Banks	3. Cash and Due From Banks Included in cash and due from banks are legal reserve requirements which must be maintained on an average basis in the form of cash and balances due from the Federal Reserve. The reserve balance varies depending upon the types and amounts of deposits. At December 31, 2018, the required reserve balance on deposit with the Federal Reserve Bank was approximately $30.9 million.
Securities	4. Debt Securities Investments in securities are accounted for as follows: Available-for-Sale Securities Securities classified as available-for-sale are those securities that are intended to be held for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including movements in interest rates, liquidity needs, security risk assessments, changes in the mix of assets and liabilities and other similar factors. These securities are carried at their estimated fair value, and the net unrealized gain or loss is reported net of tax, as component of accumulated other comprehensive income (loss) in stockholders’ equity, until realized. Premiums and discounts are recognized in interest income using the interest method. Gains and losses on the sale of available-for-sale securities are determined using the adjusted cost of the specific security sold. Securities to be Held-to-Maturity Securities classified as held-to-maturity are those securities for which there is a positive intent and ability to hold to maturity. These securities are carried at cost adjusted for amortization of premiums and accretion of discounts, computed by the interest method. Trading Account Securities Trading account securities are those securities which are held for the purpose of selling them at a profit. There were no trading account securities on hand at December 31, 2018, 2017 and 2016. Equity Securities Equity securities are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Other Securities Other securities are carried at cost and are restricted in marketability. Other securities consist of investments in the Federal Home Loan Bank (FHLB), Federal Reserve Bank and First National Bankers’ Bankshares, Inc. Management reviews for impairment based on the ultimate recoverability of the cost basis. Shares of Federal Home Loan Bank (FHLB), Federal Reserve Bank and First National Bankers’ Bankshares, Inc. common stock are equity securities that do not have a readily determinable fair value because their ownership is restricted and lacks marketability. The common stock is carried at cost and evaluated for impairment. The Company’s investment in member bank stock is included in other securities in the accompanying consolidated balance sheets. Management reviews for impairment based on the ultimate recoverability of the cost basis. No other-than-temporary impairment was noted for the years ended December 31, 2018, 2017 and 2016. Interest Income Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. On January 1, 2018, the Company adopted the new accounting standard for Financial Instruments, which requires investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with the changes in fair value recognized in net income. The adoption of this guidance resulted in a $348 thousand decrease to retained earnings. Other-than-Temporary Impairment (“OTTI”) Management evaluates investment securities for other-than-temporary impairment on 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 as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) other-than-temporary impairment (OTTI) related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.
Loans held for sale	5. Loans held for sale The Bank originates fixed rate single family, residential first mortgage loans on a presold basis. The Bank issues a rate lock commitment to a customer and concurrently “locks in” with a secondary market investor under a best efforts delivery mechanism. Such loans are sold without the mortgage servicing rights being retained by the Bank. The terms of the loan are dictated by the secondary investors and are transferred within several weeks of the Bank initially funding the loan. The Bank recognizes certain origination fees and service release fees upon the sale, which are included in other income on loans in the consolidated statements of income. Between the initial funding of the loans by the Bank and the subsequent purchase by the investor, the Bank carries the loans held for sale at the lower of cost or fair value in the aggregate as determined by the outstanding commitments from investors.
Loans	6. Loans Loans are carried at the principal amount outstanding, net of the allowance for loan losses. Interest income on loans is recognized based on the principal balance outstanding and the stated rate of the loan. Loan origination fees and certain direct origination costs are deferred and recognized as an adjustment of the related loan yield using the interest method. A loan is considered impaired, in accordance with the impairment accounting guidance of Accounting Standards Codification (ASC) Section 310-10-35, Receivables, Subsequent Measurement , when, based upon current events and information, it is probable that the scheduled payments of principal and interest will not be collected in accordance with the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral values, and the probability of collecting scheduled payments of principal and interest when due. Generally, impairment is measured on a loan by loan basis using the fair value of the supporting collateral. Loans are generally placed on a non-accrual status, and the accrual of interest on such loan is discontinued, when principal or interest is past due ninety days or when specifically determined to be impaired unless the loan is well-secured and in the process of collection. When a loan is placed on non-accrual status, interest accrued but not received is generally reversed against interest income. If collectability is in doubt, cash receipts on non-accrual loans are used to reduce principal rather than recorded in interest income. Past due status is determined based upon contractual terms. Loans are returned to accrual status when the obligation is brought current or has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
Allowance for Loan Losses	7. Allowance for Loan Losses The allowance for loan losses is a valuation allowance reserved for probable incurred credit losses. A charge is taken against the allowance for loan losses when management believes the collectibility of the loan principal is confirmed to be unlikely. Subsequent recoveries, if any, are credited back to the allowance. Management evaluates the adequacy of the allowance for loan losses on a regular basis. These evaluations are based upon a periodic review of the historical loan loss experience, the nature and value of the loan portfolio, underlying collateral values, internal and independent loan reviews, and prevailing economic conditions. In addition, the OCC, as a part of the regulatory examination process, reviews the loan portfolio and the allowance for loan losses and may require changes in the allowance based upon information available at the time of the examination. The allowance consists of two components, a reserve for general pool (or formula pool) loans that are collectively evaluated for impairment, and a reserve for loans individually evaluated for impairment based on expected loan specific losses. These components represent an estimation performed pursuant to either ASC Topic 450, Contingencies Receivables The Bank also has acquired loan portfolios accounted for under the acquisition method of accounting. Within these portfolios are purchased credit impaired loans accounted for under ASC Topic 310-30. Impairment may be determined specifically at an individual loan level, or estimated on various pools of loans having common risk characteristics.
Purchase Credit Impaired Loans ("PCI")	8. Purchased Credit Impaired Loans (“PCI”) The Company purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as credit score, loan type, and date of origination. The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.
Premises and Equipment	9. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. The depreciation policy is to provide for depreciation over the estimated useful lives of the assets using the straight-line method. Repairs and maintenance expenditures are charged to operating expenses; major expenditures for renewals and betterments are capitalized and depreciated over their estimated useful lives. Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts, and any gains or losses are included in operations. Building and related components are depreciated using the straight-line method with useful lives ranging from 10 to 39 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years.
Other Real Estate Owned	10. Other Real Estate Owned Other real estate owned consists of properties acquired through foreclosure and, as held for sale $10.9 million and $7.2 million, respectively.
Goodwill and Other Intangible Assets	11. Goodwill and Other Intangible Assets Goodwill totaled $89.8 million and $20.0 million for the years ended December 31, 2018, and 2017, respectively. Goodwill totaling $69.8 million was recorded during the year ended December 31, 2018, as a result of the acquisitions of First Community Bank, Sunshine Community Bank and Famers and Merchants Bank. See Note C – Business Combinations to these consolidated financial statements for additional information on the acquisitions during 2018. The Company performed the required annual impairment tests of goodwill and other intangibles as of December 1, 2018. The Company’s annual impairment test did not indicate impairment as of the testing date, and subsequent to that date, management is not aware of any events or changes in circumstances since the impairment test that would indicate that goodwill or other intangibles might be impaired. The Company’s acquisition method recognized intangible assets, which are subject to amortization, and included in other assets in the accompanying consolidated balance sheets, are core deposit intangibles, amortized on a straight-line basis, over a 10 year average life. The definite-lived intangible assets had the following carrying values at December 31, 2018 and 2017: 2018 ($ in thousands) Gross Carrying Amount Accumulated Amortization Net Carrying Amount Core deposit intangibles $ 27,752 $ (4,586 ) $ 23,166 2017 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Core deposit intangibles $ 7,640 $ (2,930 ) $ 4,710 The related amortization expense of business combination related intangible assets is as follows: ($ in thousands) Amount Aggregate amortization expense for the year ended December 31: 2016 $ 383 2017 664 2018 1,656 Amount Estimated amortization expense for the year ending December 31: 2019 $ 2,706 2020 2,706 2021 2,636 2022 2,466 2023 2,420 Thereafter 10,232 $ 23,166
Other Assets and Cash Surrender Value	12. Other Assets and Cash Surrender Value The Company invests in bank owned life insurance (BOLI). BOLI involves the purchase of life insurance by the Company on a chosen group of employees. The Company is the owner of the policies and, accordingly, the cash surrender value of the policies is reported as an asset, and increases in cash surrender values are reported as income.
Other Liabilities	13. Other Liabilities Financing costs related to the issuance of junior subordinated debentures are being amortized over the life of the instruments and are included in other liabilities.
Restricted Stock	14. Restricted Stock The Company accounts for stock based compensation in accordance with ASC Topic 718, Compensation - Stock Compensation
Income Taxes	15. Income Taxes The Company and its subsidiary file consolidated income tax returns. The subsidiary provides for income taxes on a separate return basis and remits to the Company amounts determined to be payable. Income taxes are provided for the tax effects of the transactions reported in the financial statements and consist of taxes currently payable plus deferred taxes related primarily to differences between the bases of assets and liabilities as measured by income tax laws and their bases as reported in the financial statements. The deferred tax assets and liabilities represent the future tax consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. ASC Topic 740, Income Taxes,
Advertising Costs	16. Advertising Costs Advertising costs are expensed in the period in which they are incurred. Advertising expense for the years ended December 31, 2018, 2017 and 2016, was $382 thousand, $336 thousand, and $402 thousand, respectively.
Statements of Cash Flows	17. Statements of Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash, amounts due from banks, interest-bearing deposits with banks and federal funds sold. Generally, federal funds are sold for a one to seven day period.
Off-Balance Sheet Financial Instruments	18. Off-Balance Sheet Financial Instruments In the ordinary course of business, the subsidiary bank enters into off-balance sheet financial instruments consisting of commitments to extend credit, credit card lines and standby letters of credit. Such financial instruments are recorded in the financial statements when they are exercised.
Earnings Applicable to Common Stockholders	19. Earnings Applicable to Common Stockholders Per share amounts are presented in accordance with ASC Topic 260, Earnings Per Share. Under ASC Topic 260, two per share amounts are considered and presented, if applicable. Basic per share data is calculated based on the weighted-average number of common shares outstanding during the reporting period. Diluted per share data includes any dilution from securities that may be converted into common stock, such as outstanding restricted stock. The following tables disclose the reconciliation of the numerators and denominators of the basic and diluted computations applicable to common stockholders ($ in thousands, except per share amount): For the Year Ended December 31, 2018 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common Share $ 21,225 12,986 $ 1.63 Effect of dilutive shares: Restricted Stock 108 $ 21,225 13,094 $ 1.62 For the Year Ended December 31, 2017 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common Share $ 10,616 9,484 $ 1.12 Effect of dilutive shares: Restricted Stock 77 $ 10,616 9,561 $ 1.11 For the Year Ended December 31, 2016 Net Income (Numerator) Weighted Average Shares (Denominator) Per Share Amount Basic per common share $ 9,666 5,435 $ 1.78 Convertible Preferred dividend 134 Effect of dilutive shares: Convertible Preferred , Series E 742 Restricted Stock 82 $ 9,800 6,259 $ 1.57 The diluted per share amounts were computed by applying the treasury stock method.
Mergers and Acquisitions	20. Mergers and Acquisitions Business combinations are accounted for under ASC 805, “ Business Combinations ”, using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversion, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the non-interest expense caption.
Investment in Limited Partnership	21. Investment in Limited Partnership The Company invested $ 4.4 $3.4 million at December 31, 2018 and $3.8 million at December 31, 2017, net of amortization, using the proportional method and is reported in other assets on the Consolidated Balance Sheets. The Company’s maximum exposure to loss is limited to the carrying value of its investment. The Company received $481 thousand in low-income housing tax credits during 2018, $481 thousand in 2017 and $160 thousand in 2016.
Reclassifications	22. Reclassifications Certain reclassifications have been made to the 2017 and 2016 financial statements to conform with the classifications used in 2018. These reclassifications did not impact the Company's consolidated financial condition or results of operations.
Accounting Pronouncements	23. Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-11 eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect for early adoption the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. The revised disclosure requirements will not have a material impact on the Company’s Consolidated Financial Statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 has been issued as part of a simplification initiative which will expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees and expands the scope through the amendments to address and improve aspects of the accounting for non-employee share-based payment transactions. The amendments will be effective for interim and annual reporting periods beginning after December 15, 2018. The Company is currently evaluating the provisions of ASU 2018-07 to determine the potential impact the new standard will have on its Consolidated Financial Statements. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. In February, 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . ASU No. 2018-02 allows for the reclassification from other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the Act). ASU 2018-02 also allows an accounting policy election to reclassify other stranded tax effects that relate to the Act but are not directly related to the change in federal tax rate. ASU 2018-02 is effective in the first quarter of 2019. Early adoption is permitted for reporting periods for which financial statements have not yet been issued. The Company adopted ASU 2018-02 in the fourth quarter of 2017 by retrospective application. Upon adoption, the Company made a policy election to reclassify stranded tax effects of approximately $76 thousand from Accumulated Other Comprehensive Income to retained earnings using the specific identification method. In May 2017, the FASB issued ASU No. 2017-09, “ Stock Compensation, Scope of Modification Accounting.” In March 2017, the FASB issued ASU No. 2017-08, “ Premium Amortization on Purchased Callable Debt Securities.” In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for any impairment tests performed after January 1, 2017. The Company is currently assessing the impact of ASU 2017-04 on its Consolidated Financial Statements. In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 included specific guidance on how to classify certain transactions in the statement of cash flows and reduced diversity in practice in how eight particular transactions are classified in the statement of cash flows. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Entities were required to apply the guidance retrospectively unless it would have been impracticable to do, in which case the amendments could have been applied prospectively. The Company applied the guidance retrospectively. As this guidance only affects the classification within the statement of cash flows, ASU 2016-15 did not have a material impact on the Company's Consolidated Financial Statements. In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” . ASU 2016-13 requires a new impairment model known as the current expected credit loss (“CECL”) which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. The main provisions of ASU 2016-13 include (1) replacing the “incurred loss” approach under current GAAP with an “expected loss” model for instruments measured at amortized cost, (2) requiring entities to record an allowance for credit losses related to available-for-sale debt securities rather than a direct write-down of the carrying amount of the investments, as is required by the other-than-temporary-impairment model under current GAAP, and (3) a simplified accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, although early adoption is permitted. The Company is currently working with a third party to assess the impact of the adoption of ASU 2016-13 on its Consolidated Financial Statements. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption could be influenced by the composition, characteristics and quality of our loan portfolio as well as the prevailing economic conditions and forecasts as of the adoption date. As part of our implementation process, we have established a working group that includes individuals from various functional areas that made initial assessments regarding portfolio segmentation, reviewed system requirements, engaged a third party software vendor, and have begun to model expected loss estimates. In February 2016, the FASB issued ASU No. 2016-02 “ Leases (Topic 842).” ASU 2016-02 establishes a right of use model that requires a lessee to record a right of use asset and a lease liability for all leases with terms longer than 12 months. Leases will be classified as either finance or operating with classification affecting the pattern of expense recognition in the income statement. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If neither risks and rewards nor control is conveyed, an operating lease results. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with certain practical expedients available. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Leases – Targeted Improvements. ASU 2018-11 provides entities with relief from the costs of implementing certain aspects of ASU 2016-02. Under the amendments in ASU 2018-11 entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard and lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02, January 1, 2019. We have elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. Our operating leases relate primarily to bank branches. Based on our lease portfolio as of December 31, 2018, we anticipate recognizing a lease liability on our balance sheet of approximately $1.8 million with an offsetting right-of-use asset. In May 2014, the FASB issued ASU No. 2014-09 “Revenue from Contracts with Customers (Topic 606)”
