SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation —The consolidated financial statements include the accounts of MidSouth Bancorp, Inc. (the “Company”) and its wholly owned subsidiary MidSouth Bank, N.A. (the “Bank”). All significant intercompany accounts and transactions have been eliminated in consolidation. We are subject to regulation under the Bank Holding Company Act of 1956. The Bank is primarily regulated by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation (“FDIC”). We are a bank holding company headquartered in Lafayette, Louisiana operating principally in the community banking business by providing banking services to commercial and retail customers through the Bank. The Bank is community oriented and focuses primarily on offering competitive commercial and consumer loan and deposit services to individuals and small to middle market businesses in Louisiana and central and east Texas. The accounting principles we follow and the methods of applying these principles conform with accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. In preparing the financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses, the valuation of real estate acquired in connection with or in lieu of foreclosure on loans, the assessment of goodwill for impairment, and valuation allowances associated with the realization of deferred tax assets which are based on future taxable income. Given the current instability of the economic environment, it is reasonably possible that the methodology of the assessment of potential loan losses, losses on other real estate owned, goodwill impairment, and other fair value measurements could change in the near term or could result in impairment going forward. A summary of significant accounting policies follows: Cash and cash equivalents —Cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits in other banks with original maturities of less than 90 days, and federal funds sold. Investment Securities —We determine the appropriate classification of debt securities at the time of purchase and reassesses this classification periodically. Trading account securities are held for resale in anticipation of short-term market movements. Debt securities are classified as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. Securities not classified as held-to-maturity or trading are classified as available-for-sale. We had no trading account securities during the three years ended December 31, 2017 . Held-to-maturity securities are stated at amortized cost. Available-for-sale securities are stated at fair value, with unrealized gains and losses, net of deferred taxes, reported as a separate component of stockholders’ equity. The amortized cost of debt securities classified as held-to-maturity or available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity or, in the case of mortgage-backed securities, over the estimated life of the security. Amortization, accretion, and accrued interest are included in interest income on securities. Realized gains and losses on the sale of investment securities are included in earnings and are determined using the specific-identification method. Management evaluates investment securities for other than temporary impairment on a quarterly basis. A decline in the fair value of available-for-sale and held-to-maturity securities below cost that is deemed other than temporary is charged to earnings for a decline in value deemed to be credit related and a new cost basis for the security is established. The decline in value attributed to non-credit related factors is recognized in other comprehensive income. Other Investments —Other investments include Federal Reserve Bank and Federal Home Loan Bank stock, as well as other correspondent bank stocks and our CRA investment, which have no readily determined market value and are carried at cost. Due to the redemption provisions of the investments, the fair value equals cost and no impairment exists. Loans Held For Sale —Loans are classified as held for sale when management has positively determined that the loans will be sold in the foreseeable future and the Company has the ability to do so. The classification may be made upon origination or subsequent to the origination or purchase. Once a decision has been made to sell loans not previously classified as held for sale, such loans are transferred into the held for sale classification and carried at the lower of cost or estimated fair value. Fair value is based on commitments from investors or prevailing market prices. Gains and losses on sales are recorded in noninterest income or expense. Loans —Loans that we have the intent and ability to hold for the foreseeable future or until maturity are reported at the principal amount outstanding, net of the allowance for loan losses and any deferred fees or costs on originated loans. Interest income on commercial and real estate mortgage loans is calculated by using the simple interest method on the daily balance of the principal amount outstanding. Unearned income on installment loans is credited to operations based on a method which approximates the interest method. The special assets and the collections departments are responsible for validating loans past due for reporting purposes. Once loans are determined to be past due, both departments actively works with customers to bring loans back to current status. We consider a loan to be impaired when, based upon current information and events, we believe it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans above a specific threshold classified as special mention, substandard, or doubtful, based on credit risk rating factors, are reviewed for potential impairment. Our impaired loans include troubled debt restructurings and performing and nonperforming major loans in which full payment of principal or interest is not expected. All TDRs, regardless of the outstanding balance, are reviewed for potential impairment. We calculate the allowance required for impaired loans based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. A loan may be impaired but not on nonaccrual status when available information suggests that it is probable the Bank may not receive all contractual principal and interest, however, the loan is still current and payments are received in accordance with the terms of the loan. Payments received for impaired loans not on nonaccrual status are applied to principal and interest. All impaired loans are reviewed, at minimum, on a quarterly basis. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. After this review, when comparing the resulting collateral valuation to the outstanding loan balance, if the discounted collateral value exceeds the loan balance no specific allocation is reserved. All loans included in our impairment analysis are subject to the same procedure and review, with no distinction given to the dollar amount of the loan. Our Credit Risk Committee meets monthly to review loans with adverse classifications. Loans greater than or equal to $1,000,000 with adverse classifications are reviewed monthly; loans between $250,000 and $1,000,000 with adverse classifications are reviewed quarterly. Loan officers, loan review officers, and special assets officers contribute updated information on each credit, reviewing potential declines or improvements in the borrower’s repayment ability and our collateral position. If deterioration in our collateral position is determined, additional discounts may be applied to the impairment analysis before the new appraisal is received. The committee makes a determination of whether the loans reviewed have reached a point of collateral dependency and sufficient doubt exists as to collectibility. As a matter of policy, loans are placed on nonaccrual status when, in the judgment of committee members, the probability of collection of interest is deemed insufficient to warrant further accrual. For loans placed on nonaccrual status, the accrual of interest is discontinued and subsequent payments received are applied to the principal balance. Interest income is recorded after principal has been satisfied and as payments are received. Additionally, loans may be placed on nonaccrual status when the loan becomes 90 days past due and any of the following conditions exist: it becomes evident that the borrower will not make payments or will not or cannot meet the Bank’s terms for the renewal of a matured loan, full repayment of principal and interest is not expected, the loan has a credit risk rating of substandard, the borrower files bankruptcy and an approved plan of reorganization or liquidation is not anticipated in the near future, or foreclosure action is initiated. When a loan is placed on nonaccrual status, previously accrued but unpaid interest for the current year is deducted from interest income. Prior year unpaid interest is charged to the allowance for loan losses. Some loans may continue accruing after 90 days if the loan is in the process of renewing, being paid off, or the underlying collateral fully supports both the principal and accrued interest and the loan is in the process of collection. Nonaccrual loans may be returned to accrual status if all principal and interest amounts contractually owed are reasonably assured of repayment within a reasonable period and there is a period of at least six months to one year of repayment performance by the borrower depending on the contractual payment terms. When loans are returned to accrual status, interest income that was previously applied to the principal balance is not reversed but is recognized into interest income as an adjustment to the yield over the remaining life of the loan. Our Director of Special Assets and CCO must approve the return of loans to accrual status as well as exceptions to any requirements of the non-accrual policy. Generally, commercial, financial, and agricultural loans; construction loans; commercial real estate loans; consumer loans; and finance leases which become 90 days delinquent are either in the process of collection through repossession or foreclosure or are deemed currently uncollectible. The portion of loans deemed currently uncollectible, due to insufficient collateral, are charged-off against the allowance for loan losses. All loans requested to be charged-off must be specifically authorized by the Director of Special Assets and the CCO. Requests may be initiated by collection personnel, bank counsel, loan review, and lending personnel. Charge-offs will be reviewed by the Director of Special Assets and the CCO to ensure the propriety and accuracy of charge-off recommendations. Factors considered when determining loan collectibility and amount to be charged off for all segments in our loan portfolio include delinquent principal or interest repayment, the ability of borrower to make future payments, collateral value of outstanding debt, and the adequacy of guarantors support. It is the responsibility of the Director of Special Assets to report all charge-offs to the Credit Risk Committee for ratification. Credit Risk Rating —We manage credit risk by observing written underwriting standards and lending policy established by the Board of Directors and management to govern all lending activities. The risk management program requires that each individual loan officer review his or her portfolio on a quarterly basis and assign recommended credit ratings on each loan. These efforts are supplemented by independent reviews performed by a loan review officer and other validations performed by the internal audit department. The results of the reviews are reported directly to the Audit Committee of the Board of Directors. Additionally, Bank concentrations are monitored and reported quarterly for risk rating distributions, major standard industry classification segments, real estate concentrations, and collateral distributions. Consumer and residential real estate loans are normally graded at inception, and the grade generally remains the same throughout the life of the loan. Loan grades on commercial, financial, and agricultural; construction; commercial real estate; and finance leases may be changed at any time when circumstances warrant, and are at a minimum reviewed quarterly. Loans can be classified into the following three risk rating groupings: pass, special mention, and substandard/doubtful. Factors considered in determining a risk rating grade include debt service capacity, capital structure/liquidity, management, collateral quality, industry risk, company trends/operating performance, repayment source, revenue diversification/customer concentration, quality of financial information, and financing alternatives. Pass grade signifies the highest quality of loans to loans with reasonable credit risk, which may include borrowers with marginally adequate financial performance, but have the ability to repay the debt. Special mention loans have potential weaknesses that warrant extra attention from the loan officer and other management personnel, but still have the ability to repay the debt. Substandard classification includes loans with well-defined weaknesses with risk of potential loss. Loans classified as doubtful are considered to have little recovery value and are charged off. Allowance for Loan Losses —The allowance for loan losses is a valuation account available to absorb probable losses on loans. All losses are charged to the allowance for loan losses when the loss actually occurs or when a determination is made that a loss is likely to occur. Recoveries are credited to the allowance for loan losses at the time of recovery. Quarterly, we estimate the probable level of losses in the existing portfolio through consideration of such factors including, but not limited to, past loan loss experience; estimated losses in significant credits; known deterioration in concentrations of credit; trends in nonperforming assets; volume and composition of the loan portfolio, including percentages of special mention, substandard and past due loans; lending policies and control systems; known inherent risks in the portfolio; adverse situations that may affect the borrower’s ability to repay; the estimated value of any underlying collateral; current national and local economic conditions, including the unemployment rate, the price of oil, and real estate absorption time; the experience, ability and depth of lending management; collections personnel experience; and the results of examinations of the loan portfolio by regulatory agencies and others. Based on these estimates, the allowance for loan losses is increased by charges to earnings and decreased by charge-offs (net of recoveries). The allowance is composed of general reserves and specific reserves. General reserves are determined by applying loss percentages to segments of the portfolio. The loss percentages are based on each segment’s historical loss experience, generally over the past three to five years, and adjustment factors derived from conditions in the Bank’s internal and external environment. All loans considered to be impaired are evaluated on an individual basis to determine specific reserve allocations in accordance with GAAP. Loans for which specific reserves are provided are excluded from the calculation of general reserves. We have an internal loan review department that is independent of the lending function to challenge and corroborate the loan grade assigned by the lender and to provide additional analysis in determining the adequacy of the allowance for loan losses. Management and the Board of Directors believe the allowance for loan losses is appropriate at December 31, 2017 . While determination of the allowance for loan losses is based on available information at a given point in time, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review our allowance for loan losses. Such agencies may require us to recognize additions or deductions to the allowance based on their judgment and information available to them at the time of their examination. Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation are: Buildings and improvements 10 - 40 years Furniture, fixtures, and equipment 3 - 10 years Automobiles 3 - 5 years Leasehold improvements are amortized over the estimated useful lives of the improvements or the term of the lease, whichever is shorter. Goodwill and Other Intangible Assets —Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangible assets deemed to have an indefinite useful life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also, in connection with business combinations involving banks and branch locations, we generally record core deposit intangibles representing the value of the acquired core deposit base. Core deposit intangibles are amortized over the estimated useful life of the deposit base, generally on either a straight-line basis not exceeding 15 years or an accelerated basis over 10 years . The remaining useful lives of core deposit intangibles are evaluated periodically to determine whether events and circumstances warrant revision of the remaining period of amortization. Cash Surrender Value of Life Insurance —Life insurance contracts represent single premium life insurance contracts on the lives of certain officers of the Company. The Company is the beneficiary of these policies. These contracts are reported at their cash surrender value and changes in the cash surrender value are included in other noninterest income. Other Real Estate Owned —Real estate properties acquired through, or in lieu of, loan foreclosures are initially recorded at fair value less estimated costs to sell based on a current valuation at the time of foreclosure. After foreclosure, valuations are periodically performed by management and a charge to earnings is recorded if the carrying value of a property exceeds its fair value less estimated costs to sell. Revenues and expenses from operations and changes in the valuation allowance are charged to earnings. Assets Held For Sale —Branch closures are evaluated to determine if the related land, buildings and building improvements should be transferred to assets held for sale in accordance with FASB ASC Topic 360, “Property, Plant and Equipment.” The property is transferred to assets held for sale at the lower of its carrying value or fair value less cost to sell. An impairment loss is recorded at the time of transfer if the carrying value of the assets exceeds the fair value. Impairment losses are recorded as non-interest expense. Derivatives —Derivative financial instruments are recognized as assets and liabilities on the consolidated balance sheets and, as required by ASC 815, the Company records all derivatives at fair value. Accounting for changes in fair value of derivatives differs depending on whether the derivative has been designated and qualifies as part of a hedge relationship, and further, on the type of relationship. Derivatives Designated as Hedging Relationships The Company has entered into forward interest rate swap contracts to minimize the variability of future cash flows that is caused by changes in interest rates or other economic factors. These derivative instruments were designated as cash flow hedges under ASC Topic 815, Derivatives and Hedging. For cash flow hedges, the effective portion of the gain or loss related to the derivative instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately. Derivatives Not Designated as Hedging Relationships The Company offers certain derivative instruments directly to qualified commercial lending clients seeking to manage their interest rate risk. These derivative instruments, including interest rate swap agreements, are not designated for hedge accounting and changes in fair value are recognized in earnings immediately. Interest rate swaps are contracts in which a series of interest rate cash flows are exchanged over a prescribed period. The notional balance of interest rate swap agreements held by the Company at December 31, 2017 and 2016 was minimal and not material to the consolidated balance sheets. Repurchase Agreements —Securities sold under agreements to repurchase are secured borrowings treated as financing activities and are carried at the amounts at which the securities will be subsequently reacquired as specified in the respective agreements. Deferred Compensation —We record the expense of deferred compensation agreements over the service periods of the persons covered under these agreements. Income Taxes —Deferred tax assets and liabilities are recorded for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits, such as net operating loss carry forwards, are recognized to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. In the event the future tax consequences of differences between the financial reporting bases and the tax bases of our assets and liabilities results in deferred tax assets, an evaluation of the probability of being able to realize the future benefits indicated by such assets is required. A valuation allowance is provided when it is more likely than not that a portion or the full amount of the deferred tax asset will not be realized. In assessing the ability to realize the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. A deferred tax liability is not recognized for portions of the allowance for loan losses for income tax purposes in excess of the financial statement balance. Such a deferred tax liability will only be recognized when it becomes apparent that those temporary differences will reverse in the foreseeable future. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent more likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. Stock-Based Compensation —We expense stock-based compensation based upon the grant date fair value of the related equity award over the requisite service period of the employee. The Company accounts for stock-based forfeitures as they occur. Basic and Diluted Earnings Per Common Share —Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. Diluted EPS is computed by dividing net earnings by the total of the weighted-average number of shares outstanding plus the dilutive effect of outstanding options. The amounts of common stock and additional paid-in capital are adjusted to give retroactive effect to large stock dividends. Small stock dividends, or dividends less than 25% of issued shares at the declaration date, are reflected as an increase in common stock and additional paid-in capital and a decrease in retained earnings for the market value of the shares on the date the dividend is declared. Comprehensive Income —Generally all recognized revenues, expenses, gains and losses are included in net earnings. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net earnings, are components of comprehensive income. We present comprehensive income in a separate consolidated statement of comprehensive income. Statements of Cash Flows —For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold, and interest-bearing deposits in other banks with original maturities of less than 90 days. Generally, federal funds are sold for one -day periods. Recent Accounting Pronouncements —

For debt securities, the Company considers its intent to sell the securities or if it is more likely than not the Company will be required to sell the securities. If such impairment is identified, based upon the intent to sell or the more likely than not threshold, the carrying amount of the security is reduced to fair value with a charge to earnings. Upon the result of the aforementioned review, management then reviews for potential other than temporary impairment based upon other qualitative factors. In making this evaluation, management considers changes in market rates relative to those available when the security was acquired, changes in market expectations about the timing of cash flows from securities that can be prepaid, performance of the debt security, and changes in the market’s perception of the issuer’s financial health and the security’s credit quality. If determined that a debt security has incurred other than temporary impairment, then the amount of the credit related impairment is determined. For equity securities, management reviews the near term prospects of the issuer, the nature and cause of the unrealized loss, the severity and duration of the impairments and other factors when determining if an unrealized loss is other than temporary. If a credit loss is evident, the amount of the credit loss is charged to earnings and the non-credit related impairment is recognized through other comprehensive income. As of December 31, 2017 , 84 securities had unrealized losses totaling 2.05% of the individual securities’ amortized cost basis and 1.51% of the Company’s total amortized cost basis. 46 of the 84 securities had been in an unrealized loss position for over twelve months at December 31, 2017 . These 46 securities had an amortized cost basis and unrealized loss of $175.5 million and $5.0 million , respectively. The unrealized losses on securities at December 31, 2017 and 2016 resulted from changing market interest rates over the yields available at the time the underlying securities were purchased. Management identified no impairment related to credit quality. At December 31, 2017 and 2016 , management had both the intent and ability to hold impaired securities, and no impairment was evaluated as other than temporary. As a result, no impairment losses were recognized on securities during the years ended December 31, 2017 , 2016 , or 2015 . During the year ended December 31, 2017 , the Company sold 16 securities classified as available-for-sale and 1 security classified as held-to-maturity. Of the available-for-sale securities, 13 securities were sold with gains totaling $449,000 and 3 securities were sold at a loss of $109,000 for a net gain of $340,000 . The decision to sell the 1 held-to-maturity security, which was sold at a gain of $7,000 , was based on the pre-refunding of the bond which would accelerate the maturity of the bond by 15 years with an anticipated call date within six months. During the year ended December 31, 2016 , the Company sold 2 securities classified as available-for-sale at a gross gain of $20,000 . During the year ended December 31, 2015, the Company sold 22 securities classified as available-for-sale at a net gain of $1.2 million . Of the 22 securities sold, 12 were sold with gains totaling $1.4 million and 10 securities were sold at a loss of $135,000 . Securities with an aggregate carrying value of approximately $177.9 million and $293.4 million at December 31, 2017 and 2016 , respectively, were pledged to secure public funds on deposit and for other purposes required or permitted by law.

An analysis of the activity in the allowance for loan losses is as follows (in thousands): December 31, 2017 2016 2015 Balance, beginning of year $ 24,372 $ 19,011 $ 11,226 Provision for loan losses 30,200 10,600 13,900 Recoveries 1,193 776 459 Loans charged-off (28,877 ) (6,015 ) (6,574 ) Balance, end of year $ 26,888 $ 24,372 $ 19,011 The Company monitors loan concentrations and evaluates individual customer and aggregate industry leverage, profitability, risk rating distributions, and liquidity for each major standard industry classification segment. At December 31, 2017 , one industry segment concentration, the oil and gas industry, aggregates more than 10% of the loan portfolio. The Company’s exposure in the oil and gas industry, including related service and manufacturing industries, totaled approximately $179.7 million , or 15.2% of total loans. Of the $179.7 million loans to borrowers in the oil and gas industry, $16.2 million or 9.0% were on nonaccrual status at December 31, 2017. Additionally, the Company’s exposure to CRE loans is monitored.

Loans are analyzed individually and classified according to their credit risk. This analysis is performed on a continuous basis. The following definitions are used for risk ratings: Special Mention: Weakness exists that could cause future impairment, including the deterioration of financial ratios, past due status, and questionable management capabilities. Collateral values generally afford adequate coverage but may not be immediately marketable. Substandard: Specific and well-defined weaknesses exist that may include poor liquidity and deterioration of financial ratios. Currently the borrower maintains the capacity to service the debt. The loan may be past due and related deposit accounts experiencing overdrafts. Immediate corrective action is necessary. Doubtful: Specific weaknesses characterized as Substandard exist that are severe enough to make collection in full unlikely. There is no reliable secondary source of full repayment. Loans classified as Doubtful will usually be placed on non-accrual status. The probability of some loss is extremely high but because of certain important and reasonably specific factors, the amount of loss cannot be determined. Loans not meeting the criteria above that are analyzed individually as part of the above-described process are considered to be Pass rated loans.

If it is determined losses are probable on such TDRs, either because of delinquency or other credit quality indicator, the Company establishes specific reserves for these loans. As of December 31, 2017 , there were no commitments to lend additional funds to debtors owing sums to the Company whose terms have been modified in TDRs. In the opinion of management, all transactions entered into between the Company and such related parties have been and are made in the ordinary course of business, on substantially the same terms and conditions, including interest rates and collateral, as similar transactions with unaffiliated persons and do not involve more than the normal risk of collection.

The Company early adopted ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, for the fiscal year ending December 31, 2017, which allowed a one-time reclassification of $324,000 from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets and liabilities as of December 31, 2017 and 2016 are as follows (in thousands): 2017 (1) 2016 Deferred tax assets: Allowance for loan losses $ 5,860 $ 9,177 Loss on transfer of loans to held-for-sale 1,266 — Unrealized losses on securities 713 890 Write-down on assets held-for-sale 285 — Core deposit intangible 153 37 Deferred compensation 358 696 Other 667 640 Total deferred tax assets 9,302 11,440 Deferred tax liabilities: Premises and equipment 1,589 3,318 Goodwill 1,321 1,820 FHLB stock dividends 57 80 Unrealized gains on cash flow hedges 226 346 Prepaid expenses 220 306 Purchase accounting adjustments on securities 392 753 Other 105 245 Total deferred tax liabilities 3,910 6,868 Net deferred tax asset $ 5,392 $ 4,572 (1) For 2017, the amounts presented are reflective of the 21 percent tax rate. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, the Company believes that it is more likely than not that it will realize the benefits of these deductible differences existing at December 31, 2017 . Therefore, no valuation allowance is necessary at this time. The net deferred tax assets for 2017 and 2016 are included in other assets on the consolidated balance sheets. Components of income tax (benefit) expense are as follows (in thousands): 2017 2016 2015 Current $ (1,719 ) $ 5,439 $ 6,368 Deferred benefit (4,474 ) (1,582 ) (1,785 ) Write-down of net deferred tax asset resulting from the Tax Cuts and Jobs Act 3,595 — — Total income tax (benefit) expense $ (2,598 ) $ 3,857 $ 4,583 The provision for federal income taxes differs from the amount computed by applying the U.S. Federal income tax statutory rate of 35% on pre-tax income as follows (in thousands): December 31, 2017 2016 2015 Taxes calculated at statutory rate $ (5,026 ) $ 4,654 $ 5,460 Increase (decrease) resulting from: Tax-exempt interest, net (524 ) (615 ) (766 ) Deferred compensation (315 ) — — Write-down of net deferred tax asset resulting from the Tax Cuts and Jobs Act 3,595 — — Other (328 ) (182 ) (111 ) $ (2,598 ) $ 3,857 $ 4,583 The Company’s federal income tax returns are open and subject to examination from the 2014 tax return year and forward. The various state income and franchise tax returns are generally open from the 2014 and later tax return years based on individual state statutes of limitation. We are not currently under examination by federal or state tax authorities for the 2014 , 2015 , or 2016 tax years.

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFITS	EMPLOYEE BENEFITS The Company sponsors a leveraged employee stock ownership plan (“ESOP”) that covers all employees who meet minimum age and service requirements. The Company makes annual contributions to the ESOP in amounts as determined by the Board of Directors. These contributions are used to pay debt service and purchase additional shares. Certain ESOP shares are pledged as collateral for this debt. As the debt is repaid, shares are released from collateral and allocated to active employees, based on the proportion of debt service paid in the year. During 2014, the ESOP borrowed $283,000 payable to MidSouth Bank, N.A for the purpose of purchasing additional shares of MidSouth Bancorp, Inc.’s common stock. The loan proceeds were used to purchase a total of 16,000 shares at an average price of $17.71 per share. During 2015, the ESOP borrowed an additional $997,000 payable to MidSouth Bank, N.A. A total of 76,526 shares at an average price of $13.02 per share were purchased with the loan proceeds. During 2016, the ESOP borrowed an additional $499,000 payable to MidSouth Bank, N.A. A total of 62,014 shares at an average price of $8.05 were purchased with the loan proceeds. During 2017, all outstanding ESOP loans were consolidated into one loan that matures on August 5, 2024. The balances of the notes payable of the ESOP were $937,000 and $1.2 million at December 31, 2017 and December 31, 2016 , respectively. Because the source of the loan payments are contributions received by the ESOP from the Company, the related notes receivable is shown as a reduction of stockholders’ equity. In accordance with GAAP, compensation costs relating to shares purchased are based on the fair value of shares committed to be released. The difference between the average fair market value and the cost of the shares allocated by the ESOP is recorded as an adjustment to additional paid-in capital. The unreleased shares are not considered outstanding in the computation of earnings per common share. Dividends on unreleased shares are recorded as compensation expense; dividends on allocated ESOP shares are recorded as a reduction of stockholders’ equity. Dividends received on ESOP shares are allocated based on shares held for the benefit of each participant and used to purchase additional shares of stock for each participant. ESOP compensation expense consisting of both cash contributions and shares committed to be released for 2017 , 2016 and 2015 was approximately $472,000 , $603,000 and $720,000 , respectively. ESOP shares as of December 31, 2017 and 2016 were as follows: 2017 2016 Allocated shares 597,663 604,385 Shares released for allocation 25,875 28,451 Unreleased shares 88,192 114,067 Total ESOP shares 711,730 746,903 Fair value of unreleased shares at December 31 $ 1,169,000 $ 1,551,000 The Company has deferred compensation arrangements with certain officers, which will provide them a fixed benefit after retirement. During 2017 and 2016, distributions related to these agreements totaled $13,000 and $49,000 , respectively. The Company recorded a liability of approximately $1.4 million at December 31, 2017 and 2016 in connection with these agreements. Deferred compensation expense recognized in 2017 , 2016 , and 2015 was approximately $74,000 , $60,000 , and $82,000 , respectively. The Company sponsors defined contribution post-retirement benefit agreements to provide death benefits for the designated beneficiaries of certain of the Company's executive officers. Under the agreements, split-dollar whole life insurance contracts were purchased on certain executive officers. The increase in the cash surrender value of the contracts, less the Bank's cost of funds, constitutes the Company's contribution to the agreements each year. In the event the insurance contracts fail to produce positive returns, the Company has no obligation to contribute to the agreements. During 2017 , 2016 , and 2015 , the Company incurred expenses of $31,000 , $2,000 and $14,000 , respectively, related to the agreements. The Company has a 401(k) retirement plan covering substantially all employees who have been employed for 90 days and meet certain other requirements. Under this plan, employees can contribute a portion of their salary within the limits provided by the Internal Revenue Code into the plan. The Company made contributions to the plan totaling $271,000 , $60,000 and $60,000 in 2017 , 2016 and 2015 , respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
EMPLOYEE STOCK PLANS	EMPLOYEE STOCK PLANS In May of 2007, our stockholders approved the 2007 Omnibus Incentive Compensation Plan to provide incentives and awards for directors, officers, and employees. “Awards” as defined in the Plan includes, with limitations, stock options (including restricted stock options), restricted stock awards, stock appreciation rights, performance shares, stock awards and cash awards, all on a stand-alone, combination, or tandem basis. The 2007 Omnibus Incentive Compensation Plan replaces the 1997 Stock Incentive Plan, which expired February of 2007. A total of 525,000 of our common shares authorized were reserved for issuance under the Plan, of which 182,288 were available to be granted as of December 31, 2017 . Stock Options – The 188,275 options outstanding at December 31, 2017 were all issued under the 2007 Omnibus Incentive Compensation Plan and are incentive stock options with a term of ten years , vesting 20% each year on the anniversary date of the grant. The following table summarizes activity relating to stock options: Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at December 31, 2014 358,073 $ 14.28 Granted 5,000 13.17 Exercised (7,655 ) 12.97 Forfeited or expired (16,042 ) 17.73 Outstanding at December 31, 2015 339,376 $ 14.13 Granted 5,000 9.30 Exercised — — Forfeited or expired (45,381 ) 15.17 Outstanding at December 31, 2016 298,995 $ 13.90 Granted — — Exercised (20,499 ) 12.97 Forfeited or expired (90,221 ) 13.62 Outstanding at December 31, 2017 188,275 $ 14.14 5.04 $ — Exercisable at December 31, 2015 162,679 $ 13.81 Exercisable at December 31, 2016 203,578 13.74 Exercisable at December 31, 2017 176,024 13.92 4.84 $ — A summary of changes in unvested options for the period ended December 31, 2017 is as follows: Number of Options Weighted Average Grant Date Fair Value Unvested options outstanding, beginning of year 95,417 $ 4.72 Granted — — Vested (39,256 ) 4.75 Forfeited (35,905 ) 4.54 Unvested options outstanding, end of year 20,256 $ 4.97 As of December 31, 2017 there was a total of $67,000 in unrecognized compensation cost related to nonvested stock option grants that is expected to be recognized over a weighted-average period of 1.3 years . The total amount of options expensed during the years ended December 31, 2017 , 2016 and 2015 was $58,000 , $162,000 and $336,000 , respectively. The fair value of each option granted is estimated on the grant date using the Black-Scholes Option Pricing Model. This model requires management to make certain assumptions, including the expected life of the option, the risk free rate of interest, the expected volatility, and the expected dividend yield. The risk free rate of interest is based on the yield of a U.S. Treasury security with a similar term. The expected volatility is based on historic volatility over a term similar to the expected life of the options. The dividend yield is based on the current yield at the date of grant. The following assumptions were made in estimating the fair value of the options granted in 2016 : 2016 Risk free rate of interest 1.7 % Expected volatility 37.4 % Dividend yield 4.2 % Average expected life (in years) 5 Weighted-average grant-date fair value $ 2.14 The total intrinsic value of the options exercised was $30,000 and $10,000 for the years ended December 31, 2017 and 2015, respectively. There were no options exercised during the year ended December 31, 2016. Restricted Stock Awards – During 2017, 2016 and 2015, the Compensation Committee of the Board of Directors of the Company made restricted stock grants under the Company’s 2007 Omnibus Incentive Compensation Plan. The restricted shares of stock are subject to the terms of a Restricted Stock Grant Agreement between the Company and each recipient. Prior to vesting, the recipient will be entitled to vote the shares and receive dividends, if any, declared by the Company with respect to its common stock. Compensation expense for restricted stock is based on the fair value of the restricted stock awards at the time of the grant, which is equal to the market value of the Company’s common stock on the date of grant. The value of the restricted stock grants that are expected to vest is amortized monthly into compensation expense over the vesting period (generally three to five years). The weighted average grant date fair value of restricted stock awards was $13.98 , $10.97 and $13.92 for the years ended December 31, 2017, 2016 and 2015, respectively. For the year ended December 31, 2017 , 2016 and 2015, compensation expense of $105,000 , $48,000 and $19,000 , respectively, was recognized related to non-vested restricted stock awards. As of December 31, 2017 , there was $635,000 of unrecognized compensation cost related to non-vested restricted stock awards granted under the plan. The unrecognized compensation cost related to restricted stock awards at December 31, 2017 is expected to be recognized over a weighted-average period of 4.1 years . The following table summarizes activity relating to non-vested restricted stock awards: Number of Shares Weighted-Average Grant Date Fair Value Non-vested at December 31, 2014 — $ — Granted 11,250 13.92 Forfeited — — Vested — — Non-vested at December 31, 2015 11,250 $ 13.92 Granted 4,439 10.97 Forfeited (925 ) 13.92 Vested — — Non-vested at December 31, 2016 14,764 $ 13.03 Granted 48,526 13.98 Forfeited (4,500 ) 13.92 Vested (700 ) 13.92 Non-vested at December 31, 2017 58,090 $ 13.74

Stockholders' Equity Note [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY The payment of dividends by the Bank to the Company is restricted by various regulatory and statutory limitations. Due to the loss reported for the year ended December 31, 2017, the Bank does not have the ability to approve dividends to the Company without prior approval from the OCC. As of December 31, 2017, the Company had $50.2 million of cash to fund general corporate obligations. For additional information regarding restrictions on our ability to pay dividends see Part II, Item 5 under the heading “Market for Registrant's Common Equity, Related Shareholder Matters, and Issuer Purchases of Equity Securities.” In August 2011, the Company redeemed 20,000 outstanding shares of Series A Preferred Stock associated with its participation in the Treasury’s Capital Purchase Plan (“CPP”) under the Troubled Asset Relief Program at its stated value of $1,000 per share with funds from our issuance of 32,000 shares of Series B preferred stock in connection with the Company’s participation under the U.S. Treasury’s Small Business Lending Fund (“SBLF”). The additional $12.0 million of net proceeds from the issuance was provided to the Bank as additional capital. The dividend rate on the Series B preferred stock was set at 1.00% for the fourth quarter of 2013 due to attaining the target 10% growth rate in qualified small business loans during the second quarter of 2013. On February 25, 2016, the dividend rate increased to 9% per annum, consistent with the Securities Purchase Agreement which states that the rate would increase if the funding was not repaid within 4.5 years after issuance. The Series B preferred stock is nonvoting except for class voting rights on matters that would adversely affect the rights of the holders of the Series B preferred stock. On December 28, 2012, the Company issued 756,511 shares of common stock and 99,971 shares of Series C Preferred Stock in connection with the PSB acquisition. The Series C Preferred Stock is entitled to the payment of noncumulative dividends, if and when declared by the Company’s Board of Directors, at the rate of 4.00% per annum, payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year, beginning on April 15, 2013. The Series C Preferred Stock ranks pari passu with the existing Senior Non-Cumulative Perpetual Preferred Stock, Series B, issued in connection with the Company’s participation under the Treasury’s SBLF and senior to the Company’s common stock. The Company may redeem the Series C Preferred Stock, subject to regulatory approval, beginning on or after the fifth anniversary of the closing date of the Merger, at a redemption price equal to the liquidation value of the Series C Preferred Stock, plus declared but unpaid dividends, if any. The Company may also redeem the Series C Preferred Stock, subject to regulatory approval, at the same redemption price prior to the fifth anniversary of the closing date in the event the Series C Preferred Stock no longer qualifies for "Tier 1 Capital” treatment by the applicable federal banking regulators. Holders may convert the Series C Preferred Stock at any time into shares of the Company’s common stock at a conversion price of $18.00 per share, subject to customary anti-dilution adjustments. In addition, the Company currently has the option to require conversion of the Series C Preferred Stock if the closing price of the Company’s common stock for 20 trading days within any period of 30 consecutive trading days, exceeds 130% of the conversion price. On June 13, 2017, the Company completed the sale of 4,583,334 shares of its common stock pursuant to an underwritten public offering, and on July 11, 2017, the Company completed the sale of an additional 516,700 shares of common stock, pursuant to the partial exercise of the option to purchase additional shares granted to the underwriter. After deducting the underwriting discount and costs associated with the capital raise, the offering resulted in net proceeds of $57.2 million . The Company, subject to regulatory approval, intends to use $32.0 million of the net proceeds to redeem all of the outstanding Series B Preferred Stock issued to the U.S. Treasury as a result of its participation in the SBLF and intends to use the remaining portion of the net proceeds to enhance its capital structure, to fund future organic growth, for working capital, and other general corporate purposes.

DERIVATIVES	DERIVATIVES On July 6, 2016, the Company entered into two forward interest rate swap contracts on a reverse repurchase agreement and long-term FHLB advances. The interest rate swap contracts were designated as derivative instruments in a cash flow hedge under ASC Topic 815, Derivatives and Hedging to convert forecasted variable interest payment to a fixed rate and the Company has concluded that the forecasted transactions are probable of occurring . For cash flow hedges, the effective portion of the gain or loss related to the derivative instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately. No ineffectiveness related to the interest rate swaps designated as cash flow hedges was recognized in the consolidated statements of income for the year ended December 31, 2017. The accumulated net after-tax income related to the effective cash flow hedge included in accumulated other comprehensive income/loss is reflected in Note 17 - Other Comprehensive (Loss) Income .

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK	12 Months Ended

Risks and Uncertainties [Abstract]
FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK	FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK The Bank is party to various financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the statements of financial condition. The contract or notional amounts of those instruments reflect the extent of the Bank’s involvement in particular classes of financial instruments. The Bank’s exposure to loan loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, standby letters of credit, and financial guarantees is represented by the contractual amount of those instruments. The Bank uses the same credit policies, including considerations of collateral requirements, in making these commitments and conditional obligations as it does for on-balance sheet instruments. Contract or Notional Amount 2017 2016 Financial instruments whose contract amounts represent credit risk: (in thousands) Commitments to extend credit $ 291,459 $ 322,788 Letters of credit 10,088 13,043 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash requirements. Substantially all of these commitments are at variable rates. Commercial letters of credit and financial guarantees are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to its customers. Approximately 82% and 77% of these letters of credit were secured by marketable securities, cash on deposit, or other assets at December 31, 2017 and 2016 , respectively.

Regulatory Capital Requirements [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the 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 financial statements. Under capital adequacy guidelines, the Company and the 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. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of common equity Tier 1 capital, Tier 1 and total capital (as defined in the regulations) to risk-weighted assets (as defined) and to average assets (as defined). In addition, the OCC has established higher individual minimum capital ratios for the Bank. Specifically, the Bank must maintain a Tier 1 leverage ratio of at least 8%, and a total risk-based capital ratio of at least 12%. As of December 31, 2017 , the most recent notifications from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.

The Basel III rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). The final rule applied to all depository institutions, top-tier bank holding companies with total consolidated assets of $500 million or more and top-tier savings and loan holding companies. The rule established a new common equity Tier 1 minimum capital requirement, increased the minimum capital ratios and assigned a higher risk weight to certain assets based on the risk associated with these assets. Certain provisions of the new rules will be phased in through January 1, 2019.

FAIR VALUE MEASUREMENTS AND DIS

FAIR VALUE MEASUREMENTS AND DISCLOSURES	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND DISCLOSURES	FAIR VALUE MEASUREMENTS AND DISCLOSURES The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale and derivative instruments are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, loans held for sale, other real estate and assets held for sale. These nonrecurring fair value adjustments typically involve the application of the lower of cost or market accounting or write-downs of individual assets. Additionally, the Company is required to disclose, but not record, the fair value of other financial instruments. Fair Value Hierarchy The Company groups assets and liabilities 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 – Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Following is a description of valuation methodologies used for assets and liabilities which are either recorded or disclosed at fair value. Cash and cash equivalents —The carrying value of cash and cash equivalents is a reasonable estimate of fair value. Securities Available-for-Sale —Securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange and U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter market funds. Securities are classified as Level 2 within the valuation hierarchy when the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the bond’s terms and conditions, among other things. Level 2 inputs are used to value U.S. Agency securities, mortgage-backed securities, municipal securities, single issue trust preferred securities, certain pooled trust preferred securities, and certain equity securities that are not actively traded. Securities Held-to-Maturity —The fair value of securities held-to-maturity is estimated using the same measurement techniques as securities available-for-sale. Other investments —The carrying value of other investments is a reasonable estimate of fair value. Loans Held For Sale —Loans held for sale are carried at the lower of carrying value or fair value. Fair value is based upon quotes or bids on these loans directly from the purchaser. Loans —For disclosure purposes, the fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For variable rate loans, the carrying amount is a reasonable estimate of fair value. The Company does not record loans at fair value on a recurring basis. No adjustment to fair value is taken related to illiquidity discounts. However, from time to time, a loan is considered impaired and an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management uses one of three methods to measure impairment, which, include collateral value, market value of similar debt, and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Impaired loans where an allowance is established based on the fair value of collateral or where the loan balance has been charged down to fair value require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and adjusts the appraisal value by taking an additional discount for market conditions and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. For non-performing loans, collateral valuations currently in file are reviewed for acceptability in terms of timeliness and applicability. Although each determination is made based on the facts and circumstances of each credit, generally valuations are no longer considered acceptable when there has been physical deterioration of the property from when it was last appraised, or there has been a significant change in the underlying assumptions of the appraisal. If the valuation is deemed to be unacceptable, a new appraisal is ordered. New appraisals are typically received within 4-6 weeks. While awaiting new appraisals, the valuation in file is utilized, net of discounts. Discounts are derived from available relevant market data, selling costs, taxes, and insurance. Any perceived collateral deficiency utilizing the discounted value is specifically reserved (as required by ASC Topic 310) until the new appraisal is received or charged off. Thus, provisions or charge-offs are recognized in the period the credit is identified as non-performing. The following sources are utilized to set appropriate discounts: market real estate agents, current local sales data, bank history for devaluation of similar property, Sheriff’s valuations and buy/sell contracts. If a real estate agent is used to market and sell the property, values are discounted 6% for selling costs and an additional 4% for taxes, insurance and maintenance costs. Additional discounts may be applied if research from the above sources indicates a discount is appropriate given devaluation of similar property from the time of the initial valuation. Cash Surrender Value of Life Insurance Policies —Fair value for life insurance cash surrender value is based on cash surrender values indicated by the insurance companies. Other Real Estate —Other real estate properties are adjusted to fair value upon transfer of the loans to other real estate, and annually thereafter to insure other real estate assets are carried at the lower of carrying value or fair value. Exceptions to obtaining initial appraisals are properties where a buy/sell agreement exists for the loan value or greater, or where we have received a Sheriff’s valuation for properties liquidated through a Sheriff sale. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the other real estate as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and adjusts the appraisal value by taking an additional discount for market conditions and there is no observable market prices, the Company records the other real estate asset as nonrecurring Level 3. Assets Held For Sale —Assets held for sale are carried at the lower of carrying value or fair value. Fair value is based upon appraised values. Derivative Instruments —The fair value of derivatives are determined by an independent valuation firm and are estimated using prices of financial instruments with similar characteristics. As a result, they are classified within Level 2 of the fair value hierarchy. Deposits —The fair value of demand deposits, savings accounts, NOW accounts, and money market deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. The estimated fair value does not include customer related intangibles. Securities Sold Under Agreements to Repurchase —The fair value approximates the carrying value of repurchase agreements due to their short-term nature. Short-term Federal Home Loan Bank advances —The fair value approximates the carrying value of short-term FHLB advances due to their short-term nature. Long-term Federal Home Loan Bank advances —The fair value of of long-term FHLB advances is estimated using a discounted cash flow analysis that applies interest rates currently being offered on similar types of borrowings with similar terms. Junior Subordinated Debentures —For junior subordinated debentures that bear interest on a floating basis, the carrying amount approximates fair value. For junior subordinated debentures that bear interest on a fixed rate basis, the fair value is estimated using a discounted cash flow analysis that applies interest rates currently being offered on similar types of borrowings. Commitments to Extend Credit, Standby Letters of Credit and Credit Card Guarantees —Because commitments to extend credit and standby letters of credit are generally short-term and made using variable rates, the carrying value and estimated fair value associated with these instruments are immaterial. Assets Recorded at Fair Value Below is a table that presents information about certain assets and liabilities measured at fair value on a recurring basis (in thousands): Assets / Liabilities Measured at Fair Value at December 31, 2017 Fair Value Measurements at December 31, 2017 Description Level 1 Level 2 Level 3 Available-for-sale securities: Obligations of state and political subdivisions $ 22,809 $ — $ 22,809 $ — GSE mortgage-backed securities 59,124 — 59,124 — Collateralized mortgage obligations: residential 198,155 — 198,155 — Collateralized mortgage obligations: commercial 2,240 — 2,240 — Mutual funds 2,061 2,061 — — Corporate debt securities 24,802 — 24,802 — Total available-for-sale securities $ 309,191 $ 2,061 $ 307,130 $ — Derivative instruments $ 1,078 $ — $ 1,078 $ — Assets / Liabilities Measured at Fair Value at December 31, 2016 Fair Value Measurements at December 31, 2016 Description Level 1 Level 2 Level 3 Available-for-sale securities: Obligations of state and political subdivisions $ 29,141 $ — $ 29,141 $ — GSE mortgage-backed securities 73,578 — 73,578 — Collateralized mortgage obligations: residential 220,202 — 220,202 — Collateralized mortgage obligations: commercial 3,082 — 3,082 — Mutual funds 2,059 2,059 — — Corporate debt securities 13,811 — 13,811 — Total available-for-sale securities $ 341,873 $ 2,059 $ 339,814 $ — Derivative instruments $ 989 $ — $ 989 $ — Certain assets and liabilities are measured at fair value on a nonrecurring basis and therefore are not included in the table above. Impaired loans are level 2 assets measured using appraisals from external parties of the collateral less any prior liens. Loans held for sale are level 2 assets measured using quotes or bids from the purchaser of the loans. Other real estate owned are also level 2 assets measured using appraisals from external parties. Assets held for sale are considered level 2 assets when measured using appraisals from third parties.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on many judgments. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

SUMMARY OF SIGNIFICANT ACCOUN33

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —The consolidated financial statements include the accounts of MidSouth Bancorp, Inc. (the “Company”) and its wholly owned subsidiary MidSouth Bank, N.A. (the “Bank”). All significant intercompany accounts and transactions have been eliminated in consolidation. We are subject to regulation under the Bank Holding Company Act of 1956. The Bank is primarily regulated by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation (“FDIC”). We are a bank holding company headquartered in Lafayette, Louisiana operating principally in the community banking business by providing banking services to commercial and retail customers through the Bank. The Bank is community oriented and focuses primarily on offering competitive commercial and consumer loan and deposit services to individuals and small to middle market businesses in Louisiana and central and east Texas. The accounting principles we follow and the methods of applying these principles conform with accounting principles generally accepted in the United States of America (“GAAP”) and with general practices within the banking industry. In preparing the financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ significantly from those estimates. Material estimates common to the banking industry that are particularly susceptible to significant change in the near term include, but are not limited to, the determination of the allowance for loan losses, the valuation of real estate acquired in connection with or in lieu of foreclosure on loans, the assessment of goodwill for impairment, and valuation allowances associated with the realization of deferred tax assets which are based on future taxable income. Given the current instability of the economic environment, it is reasonably possible that the methodology of the assessment of potential loan losses, losses on other real estate owned, goodwill impairment, and other fair value measurements could change in the near term or could result in impairment going forward.
Cash and cash equivalents	Cash and cash equivalents —Cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits in other banks with original maturities of less than 90 days, and federal funds sold.
Investment Securities	Investment Securities —We determine the appropriate classification of debt securities at the time of purchase and reassesses this classification periodically. Trading account securities are held for resale in anticipation of short-term market movements. Debt securities are classified as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. Securities not classified as held-to-maturity or trading are classified as available-for-sale. We had no trading account securities during the three years ended December 31, 2017 . Held-to-maturity securities are stated at amortized cost. Available-for-sale securities are stated at fair value, with unrealized gains and losses, net of deferred taxes, reported as a separate component of stockholders’ equity. The amortized cost of debt securities classified as held-to-maturity or available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity or, in the case of mortgage-backed securities, over the estimated life of the security. Amortization, accretion, and accrued interest are included in interest income on securities. Realized gains and losses on the sale of investment securities are included in earnings and are determined using the specific-identification method. Management evaluates investment securities for other than temporary impairment on a quarterly basis. A decline in the fair value of available-for-sale and held-to-maturity securities below cost that is deemed other than temporary is charged to earnings for a decline in value deemed to be credit related and a new cost basis for the security is established. The decline in value attributed to non-credit related factors is recognized in other comprehensive income.
Other Investments	Other Investments —Other investments include Federal Reserve Bank and Federal Home Loan Bank stock, as well as other correspondent bank stocks and our CRA investment, which have no readily determined market value and are carried at cost. Due to the redemption provisions of the investments, the fair value equals cost and no impairment exists.
Loans	Loans —Loans that we have the intent and ability to hold for the foreseeable future or until maturity are reported at the principal amount outstanding, net of the allowance for loan losses and any deferred fees or costs on originated loans. Interest income on commercial and real estate mortgage loans is calculated by using the simple interest method on the daily balance of the principal amount outstanding. Unearned income on installment loans is credited to operations based on a method which approximates the interest method. The special assets and the collections departments are responsible for validating loans past due for reporting purposes. Once loans are determined to be past due, both departments actively works with customers to bring loans back to current status. We consider a loan to be impaired when, based upon current information and events, we believe it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans above a specific threshold classified as special mention, substandard, or doubtful, based on credit risk rating factors, are reviewed for potential impairment. Our impaired loans include troubled debt restructurings and performing and nonperforming major loans in which full payment of principal or interest is not expected. All TDRs, regardless of the outstanding balance, are reviewed for potential impairment. We calculate the allowance required for impaired loans based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. A loan may be impaired but not on nonaccrual status when available information suggests that it is probable the Bank may not receive all contractual principal and interest, however, the loan is still current and payments are received in accordance with the terms of the loan. Payments received for impaired loans not on nonaccrual status are applied to principal and interest. All impaired loans are reviewed, at minimum, on a quarterly basis. Reviews may be performed more frequently if material information is available before the next scheduled quarterly review. Existing valuations are reviewed to determine if additional discounts or new appraisals are required. After this review, when comparing the resulting collateral valuation to the outstanding loan balance, if the discounted collateral value exceeds the loan balance no specific allocation is reserved. All loans included in our impairment analysis are subject to the same procedure and review, with no distinction given to the dollar amount of the loan. Our Credit Risk Committee meets monthly to review loans with adverse classifications. Loans greater than or equal to $1,000,000 with adverse classifications are reviewed monthly; loans between $250,000 and $1,000,000 with adverse classifications are reviewed quarterly. Loan officers, loan review officers, and special assets officers contribute updated information on each credit, reviewing potential declines or improvements in the borrower’s repayment ability and our collateral position. If deterioration in our collateral position is determined, additional discounts may be applied to the impairment analysis before the new appraisal is received. The committee makes a determination of whether the loans reviewed have reached a point of collateral dependency and sufficient doubt exists as to collectibility. As a matter of policy, loans are placed on nonaccrual status when, in the judgment of committee members, the probability of collection of interest is deemed insufficient to warrant further accrual. For loans placed on nonaccrual status, the accrual of interest is discontinued and subsequent payments received are applied to the principal balance. Interest income is recorded after principal has been satisfied and as payments are received. Additionally, loans may be placed on nonaccrual status when the loan becomes 90 days past due and any of the following conditions exist: it becomes evident that the borrower will not make payments or will not or cannot meet the Bank’s terms for the renewal of a matured loan, full repayment of principal and interest is not expected, the loan has a credit risk rating of substandard, the borrower files bankruptcy and an approved plan of reorganization or liquidation is not anticipated in the near future, or foreclosure action is initiated. When a loan is placed on nonaccrual status, previously accrued but unpaid interest for the current year is deducted from interest income. Prior year unpaid interest is charged to the allowance for loan losses. Some loans may continue accruing after 90 days if the loan is in the process of renewing, being paid off, or the underlying collateral fully supports both the principal and accrued interest and the loan is in the process of collection. Nonaccrual loans may be returned to accrual status if all principal and interest amounts contractually owed are reasonably assured of repayment within a reasonable period and there is a period of at least six months to one year of repayment performance by the borrower depending on the contractual payment terms. When loans are returned to accrual status, interest income that was previously applied to the principal balance is not reversed but is recognized into interest income as an adjustment to the yield over the remaining life of the loan. Our Director of Special Assets and CCO must approve the return of loans to accrual status as well as exceptions to any requirements of the non-accrual policy. Generally, commercial, financial, and agricultural loans; construction loans; commercial real estate loans; consumer loans; and finance leases which become 90 days delinquent are either in the process of collection through repossession or foreclosure or are deemed currently uncollectible. The portion of loans deemed currently uncollectible, due to insufficient collateral, are charged-off against the allowance for loan losses. All loans requested to be charged-off must be specifically authorized by the Director of Special Assets and the CCO. Requests may be initiated by collection personnel, bank counsel, loan review, and lending personnel. Charge-offs will be reviewed by the Director of Special Assets and the CCO to ensure the propriety and accuracy of charge-off recommendations. Factors considered when determining loan collectibility and amount to be charged off for all segments in our loan portfolio include delinquent principal or interest repayment, the ability of borrower to make future payments, collateral value of outstanding debt, and the adequacy of guarantors support. It is the responsibility of the Director of Special Assets to report all charge-offs to the Credit Risk Committee for ratification.
Credit Risk Rating	Credit Risk Rating —We manage credit risk by observing written underwriting standards and lending policy established by the Board of Directors and management to govern all lending activities. The risk management program requires that each individual loan officer review his or her portfolio on a quarterly basis and assign recommended credit ratings on each loan. These efforts are supplemented by independent reviews performed by a loan review officer and other validations performed by the internal audit department. The results of the reviews are reported directly to the Audit Committee of the Board of Directors. Additionally, Bank concentrations are monitored and reported quarterly for risk rating distributions, major standard industry classification segments, real estate concentrations, and collateral distributions. Consumer and residential real estate loans are normally graded at inception, and the grade generally remains the same throughout the life of the loan. Loan grades on commercial, financial, and agricultural; construction; commercial real estate; and finance leases may be changed at any time when circumstances warrant, and are at a minimum reviewed quarterly. Loans can be classified into the following three risk rating groupings: pass, special mention, and substandard/doubtful. Factors considered in determining a risk rating grade include debt service capacity, capital structure/liquidity, management, collateral quality, industry risk, company trends/operating performance, repayment source, revenue diversification/customer concentration, quality of financial information, and financing alternatives. Pass grade signifies the highest quality of loans to loans with reasonable credit risk, which may include borrowers with marginally adequate financial performance, but have the ability to repay the debt. Special mention loans have potential weaknesses that warrant extra attention from the loan officer and other management personnel, but still have the ability to repay the debt. Substandard classification includes loans with well-defined weaknesses with risk of potential loss. Loans classified as doubtful are considered to have little recovery value and are charged off.
Allowance for Loan Losses	Allowance for Loan Losses —The allowance for loan losses is a valuation account available to absorb probable losses on loans. All losses are charged to the allowance for loan losses when the loss actually occurs or when a determination is made that a loss is likely to occur. Recoveries are credited to the allowance for loan losses at the time of recovery. Quarterly, we estimate the probable level of losses in the existing portfolio through consideration of such factors including, but not limited to, past loan loss experience; estimated losses in significant credits; known deterioration in concentrations of credit; trends in nonperforming assets; volume and composition of the loan portfolio, including percentages of special mention, substandard and past due loans; lending policies and control systems; known inherent risks in the portfolio; adverse situations that may affect the borrower’s ability to repay; the estimated value of any underlying collateral; current national and local economic conditions, including the unemployment rate, the price of oil, and real estate absorption time; the experience, ability and depth of lending management; collections personnel experience; and the results of examinations of the loan portfolio by regulatory agencies and others. Based on these estimates, the allowance for loan losses is increased by charges to earnings and decreased by charge-offs (net of recoveries). The allowance is composed of general reserves and specific reserves. General reserves are determined by applying loss percentages to segments of the portfolio. The loss percentages are based on each segment’s historical loss experience, generally over the past three to five years, and adjustment factors derived from conditions in the Bank’s internal and external environment. All loans considered to be impaired are evaluated on an individual basis to determine specific reserve allocations in accordance with GAAP. Loans for which specific reserves are provided are excluded from the calculation of general reserves. We have an internal loan review department that is independent of the lending function to challenge and corroborate the loan grade assigned by the lender and to provide additional analysis in determining the adequacy of the allowance for loan losses. Management and the Board of Directors believe the allowance for loan losses is appropriate at December 31, 2017 . While determination of the allowance for loan losses is based on available information at a given point in time, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review our allowance for loan losses. Such agencies may require us to recognize additions or deductions to the allowance based on their judgment and information available to them at the time of their examination.
Premises and Equipment	Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation are: Buildings and improvements 10 - 40 years Furniture, fixtures, and equipment 3 - 10 years Automobiles 3 - 5 years Leasehold improvements are amortized over the estimated useful lives of the improvements or the term of the lease, whichever is shorter.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets —Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill and other intangible assets deemed to have an indefinite useful life are not amortized but instead are subject to review for impairment annually, or more frequently if deemed necessary. Also, in connection with business combinations involving banks and branch locations, we generally record core deposit intangibles representing the value of the acquired core deposit base. Core deposit intangibles are amortized over the estimated useful life of the deposit base, generally on either a straight-line basis not exceeding 15 years or an accelerated basis over 10 years . The remaining useful lives of core deposit intangibles are evaluated periodically to determine whether events and circumstances warrant revision of the remaining period of amortization.
Cash Surrender Value of Life Insurance	Cash Surrender Value of Life Insurance —Life insurance contracts represent single premium life insurance contracts on the lives of certain officers of the Company. The Company is the beneficiary of these policies. These contracts are reported at their cash surrender value and changes in the cash surrender value are included in other noninterest income.
Other Real Estate Owned	Other Real Estate Owned —Real estate properties acquired through, or in lieu of, loan foreclosures are initially recorded at fair value less estimated costs to sell based on a current valuation at the time of foreclosure. After foreclosure, valuations are periodically performed by management and a charge to earnings is recorded if the carrying value of a property exceeds its fair value less estimated costs to sell. Revenues and expenses from operations and changes in the valuation allowance are charged to earnings.
Derivatives	Derivatives —Derivative financial instruments are recognized as assets and liabilities on the consolidated balance sheets and, as required by ASC 815, the Company records all derivatives at fair value. Accounting for changes in fair value of derivatives differs depending on whether the derivative has been designated and qualifies as part of a hedge relationship, and further, on the type of relationship. Derivatives Designated as Hedging Relationships The Company has entered into forward interest rate swap contracts to minimize the variability of future cash flows that is caused by changes in interest rates or other economic factors. These derivative instruments were designated as cash flow hedges under ASC Topic 815, Derivatives and Hedging. For cash flow hedges, the effective portion of the gain or loss related to the derivative instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately. Derivatives Not Designated as Hedging Relationships The Company offers certain derivative instruments directly to qualified commercial lending clients seeking to manage their interest rate risk. These derivative instruments, including interest rate swap agreements, are not designated for hedge accounting and changes in fair value are recognized in earnings immediately. Interest rate swaps are contracts in which a series of interest rate cash flows are exchanged over a prescribed period. The notional balance of interest rate swap agreements held by the Company at December 31, 2017 and 2016 was minimal and not material to the consolidated balance sheets.
Repurchase Agreements	Repurchase Agreements —Securities sold under agreements to repurchase are secured borrowings treated as financing activities and are carried at the amounts at which the securities will be subsequently reacquired as specified in the respective agreements.
Deferred Compensation	Deferred Compensation —We record the expense of deferred compensation agreements over the service periods of the persons covered under these agreements.
Income Taxes	Income Taxes —Deferred tax assets and liabilities are recorded for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Future tax benefits, such as net operating loss carry forwards, are recognized to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. In the event the future tax consequences of differences between the financial reporting bases and the tax bases of our assets and liabilities results in deferred tax assets, an evaluation of the probability of being able to realize the future benefits indicated by such assets is required. A valuation allowance is provided when it is more likely than not that a portion or the full amount of the deferred tax asset will not be realized. In assessing the ability to realize the deferred tax assets, management considers the scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. A deferred tax liability is not recognized for portions of the allowance for loan losses for income tax purposes in excess of the financial statement balance. Such a deferred tax liability will only be recognized when it becomes apparent that those temporary differences will reverse in the foreseeable future. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent more likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Stock-Based Compensation	Stock-Based Compensation —We expense stock-based compensation based upon the grant date fair value of the related equity award over the requisite service period of the employee. The Company accounts for stock-based forfeitures as they occur.
Basic and Diluted Earnings Per Common Share	Basic and Diluted Earnings Per Common Share —Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. Diluted EPS is computed by dividing net earnings by the total of the weighted-average number of shares outstanding plus the dilutive effect of outstanding options. The amounts of common stock and additional paid-in capital are adjusted to give retroactive effect to large stock dividends. Small stock dividends, or dividends less than 25% of issued shares at the declaration date, are reflected as an increase in common stock and additional paid-in capital and a decrease in retained earnings for the market value of the shares on the date the dividend is declared.
Comprehensive Income	Comprehensive Income —Generally all recognized revenues, expenses, gains and losses are included in net earnings. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net earnings, are components of comprehensive income. We present comprehensive income in a separate consolidated statement of comprehensive income.
Statements of Cash Flows	Statements of Cash Flows —For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold, and interest-bearing deposits in other banks with original maturities of less than 90 days. Generally, federal funds are sold for one -day periods.
Recent Accounting Pronouncements	Recent Accounting Pronouncements — ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments was issued with the intention of improving financial reporting by requiring timely recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets not recorded at fair value based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU will be required to be implemented through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the amendments are effective. The effective date of this Update is for fiscal years beginning on or after December 15, 2019. The Company is evaluating the impact that ASU 2016-13 will have on its financial position, results of operations, and its financial statement disclosures. The Company is in the process of implementing a new software program to assist in complying with the new standard. ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. ASU 2017-03 addresses and codifies the practical considerations and application of the required disclosures under SAB Topic 11.M for the implementation of ASU 2014-09, Revenue from Contracts with Customers (Topic 606); ASU 2016-02, Leases (Topic 842); and ASU 2016-13, Financial Instruments-Credit Losses (Topic 326); Measurement of Credit Losses on Financial Instruments. The SEC Staff has emphasized on a number of occasions, including the December 2016 AICPA National Conference on Current SEC and PCAOB Developments, the requirements to disclose the potential material effects of newly issued standards and the importance of providing investors with this information. Such disclosures should explain the impact the new standard is expected to have on the financial statements and how the adoption of the new standard will affect comparability. Entities should discuss both quantitative and qualitative information as available when assessing implementation of a new standard. This ASU was effective immediately for public business entities. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment was issued in order to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amendments in this ASU, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity will then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The effective date of this Update is for fiscal years beginning on or after December 15, 2020. The Company does not expect ASU 2017-04 to have an impact on its goodwill impairment tests. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities was issued in response to diversity in practice in the amortization period for premiums of callable debt securities and in how the potential for exercise of a call is factored into current impairment assessments. As such, these amendments reduce the amortization period for certain callable debt securities carried at a premium and require the premium to be amortized over the period not to exceed the earliest call date. These amendments do not apply to securities carried at a discount. The effective date of this Update is for fiscal years beginning on or after December 15, 2018. The Company is currently amortizing premiums of callable debt securities over a period through the earliest call date. As a result, it does not expect ASU 2017-08 to have a material impact on its financial position, results of operations or its financial statement disclosures. ASU 2017-09, Compensation - Stock Compensation (Topic 350): Scope of Modification Accounting was issued in response to diversity in practice when applying the guidance in Topic 718, Compensation-Stock Compensation, to a change to the terms or conditions of a share-based payment award. The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. The amendments require an entity to account for the effects of a modification unless all of the following conditions are met: • The fair value (or intrinsic or calculated value if elected) of the modified award is the same as the value of the original award immediately before the original award was modified. • The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. • The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The effective date of this Update is for fiscal years beginning on or after December 15, 2017. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption date. Adoption of this Update is not expected to have a material effect on the Company's financial position, results of operations or its financial statement disclosures. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities was issued to better align a company's financial reporting for hedging activities with the economic objectives of those activities. The effective date of this Update is for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the consolidated balance sheet as of the date of adoption. While the Company continues to assess all potential impacts of the standard, adoption of this Update is not expected to have a material impact on the Company's consolidated financial statements. ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income was issued to provide guidance concerning treatment of the so-called stranded tax effects in accumulated other comprehensive income resulting from the reduction in the federal corporate income tax rate to 21% made by the Tax Cuts and Jobs Act of 2017, enacted on December 22 2017. ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects. ASU No. 2018-02 is effective for annual reporting periods beginning after December 15, 2018, including interim reporting periods within those periods. Early adoption is permitted for financial statements of fiscal years or interim periods which have not yet been issued. The Company elected to early adopt the standard for the fiscal year ending December 31, 2017. The adjustment from accumulated other comprehensive income to retained earnings did not have a material impact on the Company’s consolidated financial statements.
Accounting Changes, Reclassifications and Restatements	Accounting Changes, Reclassifications and Restatements - Certain items in prior financial statements have been reclassified to conform to the current presentation. On January 1, 2017, the Company adopted the provisions of ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. ASU 2016-09 requires that all income tax effects associated with share-based payment awards be reported in earnings as an adjustment to income tax expense. Previously, excess tax benefits associated with share-based payments awards were recorded in additional paid-in-capital when the excess tax benefits were realized. The requirement to report those income tax effects in earnings has been applied to settlements occurring on or after January 1, 2017. ASU 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. Previously, income tax benefits at settlement of an award were reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award's vesting period. The Company has elected to apply that change in cash flow classification on a retrospective basis, which resulted in a $281,000 and $607,000 increase to net cash from operating activities and a corresponding decrease to net cash from financing activities in the accompanying consolidated statements of cash flows for 2016 and 2015, respectively, as compared to the amounts previously reported.
