Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements and notes thereto contain all adjustments, consisting only of normal recurring adjustments, necessary to present fairly, in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the financial position of MidSouth Bancorp, Inc. (the “Company”) and its subsidiaries as of March 31, 2018 and the results of their operations and their cash flows for the periods presented. The interim financial information should be read in conjunction with the annual consolidated financial statements and the notes thereto included in the Company’s 2017 Annual Report on Form 10-K. The results of operations for the three -month period ended March 31, 2018 are not necessarily indicative of the results to be expected for the entire year. Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Summary of Significant Accounting Policies — The accounting and reporting policies of the Company conform with GAAP and general practices within the banking industry. There have been no material changes or developments in the application of accounting principles or in our evaluation of the accounting estimates and the underlying assumptions or methodologies that we believe to be Critical Accounting Policies and Estimates as disclosed in our 2017 Annual Report on Form 10-K. Recent Accounting Pronouncements — ASU 2018-03, Technical Corrections and Improvements to Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities was issued to clarify certain aspects of the guidance on recognizing and measuring financial assets and liabilities in ASU 2016-01: • Clarification regarding the ability to discontinue application of the measurement alternative for equity securities without a readily determinable fair value • Clarification of the measurement date for fair value adjustments to the carrying amount of equity securities without a readily determinable fair value for which the measurement alternative is elected • Clarification of the unit of account for fair value adjustments to forward contracts and purchased options on equity securities without a readily determinable fair value for which the measurement alternative is expected to be elected • Presentation requirements for certain hybrid financial liabilities for which the fair value option is elected • Measurement of financial liabilities denominated in a foreign currency for which the fair value option is elected • Transition guidance for equity securities without a readily determinable fair value The effective date of this Update is for fiscal years beginning on or after December 15, 2017 and for interim periods within those fiscal years beginning after June 15, 2018. Public business entities with fiscal years beginning between December 15, 2017 and June 15, 2018 are not required to adopt the amendments until interim periods beginning after June 15, 2018. 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. Adoption of New Accounting Standards — In May 2014, the FASB issued ASU 2014-09 - Revenue from Contracts with Customers , which created a new principle-based framework to determine when and how an entity recognizes revenue from its customer contracts. FASB has established a core principle for recognizing revenue within the new rules, which states that revenue should only be recorded when services are provided or goods are transferred to customers at the agreed price. The majority of our revenue-generating transactions are not subject to ASC Topic 606, including revenue generated from financial instruments, such as our loans, letters of credit and investment securities, as these activities are subject to other GAAP discussed elsewhere within our disclosures. Description of our revenue-generating activities that are within the scope of ASC Topic 606, which are presented in our income statements as components of non-interest income are as follows: • Service charges on deposits - We collect service charges on most of our non-maturity deposits accounts on a monthly basis. Our fee earned is collected monthly when a particular cycle for a non-maturity deposit account closes. Each cycle is monthly and the fee earned is for our service for the month just closed. Our performance obligations are to process transactions, pay interest (on interest-bearing accounts), collect deposits, and allow access to on-line banking applications and other services ancillary to a banking relationship. Each month when our fee is charged, our obligation is complete. The contract-relationship is a month to month obligation - i.e. our obligation to perform these services would end if the customer closes their deposit account with MidSouth. • ATM and debit card income - ATM fees primarily consist of surcharges assessed to our customers for using a non-Bank ATM or a non-Bank customer using our ATM. Debit card income represents revenues earned from interchange fees, which are earned on debit card transactions conducted with payment networks. Such fees are generally recognized concurrently with the delivery of services on a daily basis.

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 March 31, 2018 , 106 securities had unrealized losses totaling 3.17% of the individual securities’ amortized cost basis and 2.63% of the Company’s total amortized cost basis. Of the 106 securities, 45 had been in an unrealized loss position for over twelve months at March 31, 2018 . These 45 securities had an amortized cost basis and unrealized loss of $169.1 million and $7.2 million , respectively. The unrealized losses on debt securities at March 31, 2018 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 March 31, 2018 , management had the intent and ability to hold impaired securities and no impairment was evaluated as other than temporary. As a result, no other than temporary impairment losses were recognized during the three months ended March 31, 2018 . During the three months ended March 31, 2018 , the Company sold 1 security classified as available-for-sale. The security was sold at book value; therefore, no gain or loss was recorded on the transaction. During the three months ended March 31, 2017 , the Company sold 10 securities classified as available-for-sale and 1 security classified as held-to-maturity. Of the available-for-sale securities, 7 securities were sold with gains totaling $108,000 and 3 securities were sold at a loss of $109,000 for a net loss of $1,000 . 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. Securities with an aggregate carrying value of approximately $187.0 million and $177.9 million at March 31, 2018 and December 31, 2017 , respectively, were pledged to secure public funds on deposit and for other purposes required or permitted by law.

Credit Quality of Loans and Allowance for Loan Losses	Credit Quality of Loans and Allowance for Loan Losses The loan portfolio consisted of the following (in thousands): March 31, 2018 December 31, 2017 Commercial, financial and agricultural $ 401,048 $ 435,207 Real estate – construction 94,679 90,287 Real estate – commercial 438,779 448,406 Real estate – residential 145,671 146,751 Installment loans to individuals 50,888 56,398 Lease financing receivable 692 732 Other 5,498 5,645 1,137,255 1,183,426 Less allowance for loan losses (25,371 ) (26,888 ) $ 1,111,884 $ 1,156,538 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 March 31, 2018 , one industry segment concentration, the oil and gas industry, constituted 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 $172.8 million , or 15.2% of total loans. Additionally, the Company’s exposure to loans secured by commercial real estate is monitored. At March 31, 2018 , loans secured by commercial real estate (including commercial construction, farmland and multifamily loans) totaled approximately $502.5 million , 54% of which are secured by owner-occupied commercial properties. Of the $502.5 million in loans secured by commercial real estate, $26.2 million , or 5.2% , were on nonaccrual status at March 31, 2018 . 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, the probable level of losses in the existing portfolio is estimated through consideration of various factors. 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 Company’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. Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded for these loans at acquisition. Methods utilized to estimate any subsequently required allowance for loan losses for acquired loans not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance and then compared to any remaining unaccreted purchase discount. To the extent that the calculated loss is greater than the remaining unaccreted purchase discount, an allowance is recorded for such difference. The Company has 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. Additionally, the Company utilizes the services of a third party to supplement its loan review efforts. A rollforward of the activity within the allowance for loan losses by loan type and recorded investment in loans for the three months ended March 31, 2018 and 2017 is as follows (in thousands): March 31, 2018 Real Estate Coml, Fin, and Agric Construction Commercial Residential Installment loans to individuals Lease financing receivable Other Total Allowance for loan losses: Beginning balance $ 20,577 $ 596 $ 3,893 $ 837 $ 957 $ 3 $ 25 $ 26,888 Charge-offs (1,524 ) (2 ) (86 ) (3 ) (221 ) — — (1,836 ) Recoveries 276 — 6 1 36 — — 319 Provision (264 ) 159 (106 ) 64 146 — 1 — Ending balance $ 19,065 $ 753 $ 3,707 $ 899 $ 918 $ 3 $ 26 $ 25,371 Ending balance: individually evaluated for impairment $ 5,968 $ 94 $ 76 $ 20 $ 6 $ — $ — $ 6,164 Ending balance: collectively evaluated for impairment $ 13,097 $ 659 $ 3,631 $ 879 $ 912 $ 3 $ 26 $ 19,207 Loans: Ending balance $ 401,048 $ 94,679 $ 438,779 $ 145,671 $ 50,888 $ 692 $ 5,498 $ 1,137,255 Ending balance: individually evaluated for impairment $ 55,092 $ 192 $ 26,005 $ 2,088 $ 50 $ — $ — $ 83,427 Ending balance: collectively evaluated for impairment $ 345,956 $ 94,487 $ 412,774 $ 143,583 $ 50,838 $ 692 $ 5,498 $ 1,053,828 March 31, 2017 Real Estate Coml, Fin, and Agric Construction Commercial Residential Installment loans to individuals Lease financing receivable Other Total Allowance for loan losses: Beginning balance $ 16,057 $ 585 $ 5,384 $ 940 $ 1,395 $ 5 $ 6 $ 24,372 Charge-offs (1,705 ) — (823 ) (117 ) (261 ) — — (2,906 ) Recoveries 154 — 10 90 58 — — 312 Provision 3,832 (321 ) (238 ) (249 ) (222 ) (2 ) — 2,800 Ending balance $ 18,338 $ 264 $ 4,333 $ 664 $ 970 $ 3 $ 6 $ 24,578 Ending balance: individually evaluated for impairment $ 4,173 $ 9 $ 1,656 $ 217 $ 160 $ — $ — $ 6,215 Ending balance: collectively evaluated for impairment $ 14,165 $ 255 $ 2,677 $ 447 $ 810 $ 3 $ 6 $ 18,363 Loans: Ending balance $ 469,815 $ 100,248 $ 464,859 $ 159,426 $ 75,258 $ 969 $ 1,425 $ 1,272,000 Ending balance: individually evaluated for impairment $ 35,346 $ 26 $ 20,623 $ 1,956 $ 487 $ — $ — $ 58,438 Ending balance: collectively evaluated for impairment $ 434,469 $ 100,222 $ 443,802 $ 157,401 $ 74,771 $ 969 $ 1,425 $ 1,213,059 Ending balance: loans acquired with deteriorated credit quality $ — $ — $ 434 $ 69 $ — $ — $ — $ 503 Non-Accrual and Past Due Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the probability of collection of interest is deemed insufficient to warrant further accrual. For loans placed on non-accrual 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. Non-accrual 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.

Interest actually received on non-accrual loans subsequent to their transfer to non-accrual status totaled $68,000 and $244,000 for the three months ended March 31, 2018 and 2017 , respectively. Impaired Loans Loans are considered impaired when, based upon current information, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans classified as special mention, substandard, or doubtful, based on credit risk rating factors, are reviewed to determine whether impairment testing is appropriate. All loan relationships with an outstanding commitment balance above a specified threshold are evaluated for potential impairment. All loan relationships with an outstanding commitment balance below the specified threshold are assigned an allowance allocation percentage that is determined by management and adjusted periodically based on certain factors. An allowance for each impaired loan is calculated 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 collaterally dependent. All impaired loans are reviewed, at a minimum, on a quarterly basis. 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. The following table presents loans that are individually evaluated for impairment (in thousands). Interest income recognized represents interest on accruing loans modified in a TDR.

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. Loans are categorized into risk categories based on relevant information about the ability of borrowers to serve their debt, such as: current financial information, historical payment experience, credit documentation, public information, current economic trends, and other factors. 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.

The Company grants the concession in an attempt to protect as much of its investment as possible. The following tables present information about TDRs that were modified during the periods presented by portfolio segment (in thousands): Three months ended March 31, 2018 March 31, 2017 Number of loans Pre-modification recorded investment Number of loans Pre-modification recorded investment Commercial, financial and agricultural — $ — 1 $ 1,984 During the three month periods ending March 31, 2018 and 2017 , there were no defaults on any loans that were modified as TDRs during the preceding twelve months. The Company defines a payment default as any loan that is greater than 30 days past due or was past due greater than 30 days at any point during the reporting period, or since the date of modification, whichever is shorter. For purposes of the determination of an allowance for loan losses on these TDRs, as an identified TDR, the Company considers a loss probable on the loan and, as a result is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. 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 March 31, 2018 , there were no commitments to lend additional funds to debtors owing sums to the Company whose terms have been modified in TDRs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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 three months ended March 31, 2018 . The accumulated net after-tax income related to the effective cash flow hedge included in accumulated other comprehensive income is reflected in Note 6 - Other Comprehensive (Loss) Income .

Fair Value Measurement

Fair Value Measurement	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement 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 Due From Banks, Interest-Bearing Deposits in Banks and Federal Funds Sold —The carrying value of these short-term instruments 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, asset-backed securities, municipal securities, single issue trust preferred securities, certain pooled trust preferred securities, collateralized debt obligations 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 —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 the 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: in-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 10% for selling 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. Other Real Estate —Other real estate (“ORE”) 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 a Sheriff’s valuation has been received 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 ORE 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 ORE 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. 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. Derivative Financial 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 securities sold under agreements to repurchase 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 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.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies — The accounting and reporting policies of the Company conform with GAAP and general practices within the banking industry. There have been no material changes or developments in the application of accounting principles or in our evaluation of the accounting estimates and the underlying assumptions or methodologies that we believe to be Critical Accounting Policies and Estimates as disclosed in our 2017 Annual Report on Form 10-K.
Recent Accounting Pronouncements	Recent Accounting Pronouncements — ASU 2018-03, Technical Corrections and Improvements to Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities was issued to clarify certain aspects of the guidance on recognizing and measuring financial assets and liabilities in ASU 2016-01: • Clarification regarding the ability to discontinue application of the measurement alternative for equity securities without a readily determinable fair value • Clarification of the measurement date for fair value adjustments to the carrying amount of equity securities without a readily determinable fair value for which the measurement alternative is elected • Clarification of the unit of account for fair value adjustments to forward contracts and purchased options on equity securities without a readily determinable fair value for which the measurement alternative is expected to be elected • Presentation requirements for certain hybrid financial liabilities for which the fair value option is elected • Measurement of financial liabilities denominated in a foreign currency for which the fair value option is elected • Transition guidance for equity securities without a readily determinable fair value The effective date of this Update is for fiscal years beginning on or after December 15, 2017 and for interim periods within those fiscal years beginning after June 15, 2018. Public business entities with fiscal years beginning between December 15, 2017 and June 15, 2018 are not required to adopt the amendments until interim periods beginning after June 15, 2018. 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. Adoption of New Accounting Standards — In May 2014, the FASB issued ASU 2014-09 - Revenue from Contracts with Customers , which created a new principle-based framework to determine when and how an entity recognizes revenue from its customer contracts. FASB has established a core principle for recognizing revenue within the new rules, which states that revenue should only be recorded when services are provided or goods are transferred to customers at the agreed price. The majority of our revenue-generating transactions are not subject to ASC Topic 606, including revenue generated from financial instruments, such as our loans, letters of credit and investment securities, as these activities are subject to other GAAP discussed elsewhere within our disclosures. Description of our revenue-generating activities that are within the scope of ASC Topic 606, which are presented in our income statements as components of non-interest income are as follows:
