SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Principles of Consolidation : The consolidated financial statements include Franklin Financial Network, Inc. ("FFN") and its wholly-owned subsidiaries, Franklin Synergy Bank (the “Bank”) and Franklin Synergy Risk Management, Inc., together referred to as “the Company.” Intercompany transactions and balances are eliminated in consolidation. The Company was incorporated under the laws of the State of Tennessee on April 5, 2007. The Bank was incorporated under the laws of the State of Tennessee and received its Certificate of Authority from the Tennessee Department of Financial Institutions and approval of Federal Deposit Insurance Corporation (FDIC) insurance on November 2, 2007. The Bank is also a Federal Reserve member bank. The Company provides financial services through its offices in Franklin, Brentwood, Spring Hill, Murfreesboro, Nashville, Nolensville, and Smyrna, Tennessee. Its primary deposit products are checking, savings, and certificate of deposit accounts, and its primary lending products are commercial and residential construction, commercial, installment loans and lines secured by home equity. Substantially all loans are secured by specific items of collateral including commercial and residential real estate, business assets, and consumer assets. Commercial loans are expected to be repaid by cash flow from operations of businesses. The Company also focuses on electronic banking products such as internet banking, remote deposit capture and lockbox services. On July 1, 2014, Mid-South Bancorp (“Mid-South”) merged into the Bank with the Bank continuing as the surviving company. On December 28, 2015, the Company invested in a wholly-owned subsidiary, FSRM, which provides risk management services to the Company in the form of enhanced insurance coverages. On March 1, 2016, the Bank invested in a wholly-owned subsidiary, Franklin Synergy Investments of Tennessee, Inc. (“FSIT”), which provides investment services to the Bank. Also on March 1, 2016, FSIT invested in a wholly-owned subsidiary, Franklin Synergy Investments of Nevada, Inc. (“FSIN”), to provide investment services to FSIT. In addition, on March 1, 2016, FSIN invested in a subsidiary, Franklin Synergy Preferred Capital, Inc. (“FSPC”), to serve as a real estate investment trust (“REIT”), to allow the Bank to sell real estate loans to the REIT to obtain a tax benefit. FSIN has a controlling interest in the REIT, but the REIT also has a group of investors that own a noncontrolling interest in the preferred stock of the REIT. On April 1, 2018, Civic Bank & Trust merged with and into the Bank with the Bank continuing as the surviving company. See Note 2 in the notes of the consolidated financial statements. On January 21, 2020, FFN, FB Financial Corporation, a Tennessee corporation (“FB Financial”), and Paisley Acquisition Corporation, a Tennessee corporation and a direct, wholly-owned subsidiary of FB Financial (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which, on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into FFN, with FFN continuing as the surviving corporation (the “Merger”). Immediately following the Merger, FFN will merge with and into FB Financial, with FB Financial continuing as the surviving corporation (the “Upstream Merger”). Immediately following the Upstream Merger, FSB will merge with and into FirstBank, a Tennessee state-chartered bank and a wholly owned subsidiary of FB Financial (“FirstBank”), with FirstBank continuing as the surviving bank (the “Bank Merger,” and, together with the Merger and the Upstream Merger, the “Mergers”). Under the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of the common stock, no par value (the “FFN Common Stock”), issued and outstanding immediately prior to the Effective Time (except for certain shares of FFN Common Stock owned by FFN as treasury stock or by FB Financial, as provided in the Merger Agreement) will be converted, in accordance with the procedures set forth in the Merger Agreement, into the right to receive, without interest, (1) 0.9650 shares (the “Exchange Ratio”) of common stock, par value $1.00 per share, of FB Financial (“FB Financial Common Stock”) and (2) $2.00 in cash (the “Per Share Cash Consideration” and, collectively with the FB Financial Common Stock to be issued pursuant to the preceding clause (1), the “Merger Consideration”). The completion of the Mergers is subject to customary conditions, including (i) receipt of FFN shareholder approval and FB Financial shareholder approval, (ii) authorization for listing on the New York Stock Exchange of the shares of FB Financial Common Stock to be issued in the Merger, (iii) the receipt of required regulatory approvals, including the approval of the Federal Reserve Board, the Federal Deposit Insurance Corporation and the Tennessee Department of Financial Institutions, (iv) effectiveness of the registration statement on Form S-4 for the FB Financial Common Stock to be issued in the Merger, and (v) the absence of any order, injunction or other legal restraint preventing or making illegal the completion of the Merger or any of the other transactions contemplated by the Merger Agreement. Use of Estimates : To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Cash Flows : Cash and cash equivalents include cash, deposits with other financial institutions with maturities under 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions and federal funds purchased. Interest-Bearing Deposits in Financial Institutions : Interest-bearing deposits in other financial institutions are carried at cost. Securities : Debt securities were classified as held to maturity (HTM) and carried at amortized cost when management had the positive intent and ability to hold them to maturity. Debt securities are classified as available for sale (AFS) when they might be sold before maturity. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Management assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of these criteria is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. No OTTI has been recognized for the years ended December 31, 2019, 2018 or 2017. Loans Held for Sale : Loans originated and intended for sale in the secondary market are carried at fair value as of the balance sheet date as determined by outstanding commitments from investors and includes the servicing value of the loans. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Certain loans held for sale are sold with servicing rights retained. The carrying value of loans sold with retained servicing is reduced by the amount allocated to the servicing right. Gains and losses on sales of loans are based on the difference between the selling price and the carrying value of the related loan sold. Loans : Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of purchase discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income on mortgage loans and loans held for investment is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. A loan is moved to non-accrual status in accordance with the Company’s policy, typically after 90 days of non-payment. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The banking agencies define a “Shared National Credit” (“SNC”) as any loan extended to a borrower which aggregates $100 million or more and is shared by three or more banks. The SNC portfolio totaled $136,658 at December 31, 2019, decreasing 45.1% from $249,033 at December 31, 2018, driven by the sales and paydowns of $112,375 of SNCs during 2019. The entire outstanding balance of SNCs was included in the commercial and industrial portfolio. To meet the needs of our customers, SNC participations are entered into during the normal course of business and are reviewed at least quarterly for credit quality. Concentration of Credit Risk : Most of the Company’s business activity is with customers located within Williamson County, Davidson County, and Rutherford County; therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy in the Williamson County, Davidson County, and Rutherford County areas. The Company believes there are no significant concentrations of loans to any one industry or customer. However, the customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area. Purchased Credit Impaired (PCI) Loans : The Company purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination. The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Allowance for Loan Losses : The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDRs) and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. All loans classified by management as substandard or worse are individually evaluated for potential designation as impaired. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. TDRs are individually evaluated for impairment disclosures and included in the separately identified impairment disclosures. TDRs are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. TDRs are subsequently tracked and reviewed for impairment quarterly. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on a combination of the Bank’s loss history and loss history over the past three years from a group of other local banks that operate in the Middle Tennessee areas. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: • Construction and land development loans include loans to finance the process of improving, preparatory or erecting new structures or the on-site construction of industrial, commercial, residential or farm buildings. Construction and land development loans also include loans secured by vacant land, except land known to be used or usable for agricultural purposes. Construction loans generally are made for relatively short terms. They generally are more vulnerable to changes in economic conditions. Further, the nature of these loans is such that they are more difficult to evaluate and monitor. The risk of loss on a construction loan is dependent largely upon the accuracy of the initial estimate of the property’s value upon completion of the project and the estimated cost (including interest) of the project. Periodic site inspections are made on construction loans. • Commercial real estate loans include loans secured by non-residential real estate, including farmland and improvements thereon. Often these loans are made to single borrowers or groups of related borrowers, and the repayment of these loans largely depends on the results of operations and management of these properties. Adverse economic conditions may affect the repayment ability of these loans. • Residential real estate loans include loans secured by residential real estate, including single-family and multi-family dwellings. Mortgage title insurance and hazard insurance are normally required. Adverse economic conditions in the Company’s market area may reduce borrowers’ ability to repay these loans and may reduce the collateral securing these loans. • Commercial and industrial loans include loans for commercial, industrial, healthcare or agricultural purposes to business enterprises that are not secured by real estate. Commercial loans are typically made on the basis of the borrower’s ability to repay from the cash flow of the borrower’s business. Commercial and Agriculture loans are generally secured by accounts receivable, inventory and equipment. The collateral securing loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. • Consumer and other loans include loans to individuals for household, family and other personal expenditures that are not secured by real estate. Consumer loans are generally secured by customer deposit accounts, vehicles and other household goods. The collateral securing consumer loans may depreciate over time. Servicing Rights : When loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in gain on sale of loans. Fair value is based on market prices for comparable servicing contracts. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with loan servicing fees on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement as loan servicing fees, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against mortgage loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material. Transfers of Financial Assets : Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Foreclosed Assets : Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Premises and Equipment : Premises and equipment are stated at cost less accumulated depreciation and are depreciated using the straight-line method. Depreciation periods are shorter of the asset’s useful life or lease period, ranging from three Restricted Equity Securities : The Bank is a member of the Federal Reserve Bank (FRB) and the FHLB system. Members of the FRB and FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. The stock ownership in FRB and FHLB are carried at cost, classified as restricted securities, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Company Owned Life Insurance/Bank Owned Life Insurance : The Company and the Bank have purchased life insurance policies on certain key executives. Company owned life insurance/bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Goodwill and Other Intangible Assets : Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the balance sheet. Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from whole bank and branch acquisitions are amortized on an accelerated method over their estimated useful lives, which range from 7 to 10 years. Long-Term Assets : Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Loan Commitments and Related Financial Instruments : Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Mortgage Banking Derivatives : Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitment before the loan is funded. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest rate on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives are included in net gains on sale of mortgage loans. Derivatives : At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company's intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment ("fair value hedge"), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow hedge"), or (3) as instrument with no hedging designation ("stand-alone derivative"). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedged accounting are reported currently in earnings, as noninterest income. Net settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows on the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or forecasted transactions. The Company also formally assesses, both at the hedge's inception and on an ongoing bases, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted traction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. The Company is exposed to losses if a counterparty fails to make its payments under a contract in which the Company is in the net receiving position. The Company anticipates that the counterparties will be able to fully satisfy their obligations under the agreements. All the contracts to which the Company is a party settle monthly or quarterly. In addition, the Company obtains collateral above certain thresholds of the fair value of its hedges for each counterparty based upon their credit standing and the Company has netting agreements with the dealers with which it does business. Stock-Based Compensation : Compensation cost is recognized for stock options and restricted stock awards based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period, reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. All excess tax benefits and tax deficiencies related to share-based payment awards are recognized as income tax expense or benefit in the income statement during the period in which they occur. Income Taxes : Income tax expense or benefit is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. Accordingly, deferred tax assets that were realized after December 31, 2017 were remeasured using the tax rates enacted as a result of the 2017 Tax Cuts and Jobs Act resulting in an additional income tax expense of $5,323 as of December 31, 2017. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. 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% 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. Retirement Plans : Employee 401(k) and profit sharing plan expense is the amount of matching contributions. The matching contributions are paid with employer stock. Comprehensive Income (Loss) : Comprehensive income (loss) consists of the total of all components of comprehensive income (loss) including net income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive income (loss) but excluded from net income (loss). Currently, the Company's other comprehensive income (loss) consists primarily of unrealized gains and losses on securities available for sale, net of deferred tax expense (benefit) and unrealized gains (losses) on derivative hedging relations. Earnings Per Common Share : Basic earnings per common share is net income available to common shareholders divided by the weighted average number of common shares outstanding d

Business Combinations [Abstract]
BUSINESS COMBINATIONS	NOTE 2—BUSINESS COMBINATIONS As of April 1, 2018, Civic Bank & Trust merged with and into the Bank with the Bank continuing as the surviving company. Under the terms of the acquisition, Civic’s common shareholders received a total of 970,390 shares of the FFN's common stock in exchange for the outstanding shares of Civic common stock. With the completion of the acquisition, the Company has its first full service branch office in Nashville, Tennessee located in the Davidson County market. The results of Civic’s operations are included in the Company’s results since April 1, 2018. Acquisition-related costs of $565 are included in other noninterest expense in the Company’s income statement ended December 31, 2018. The fair value of the common shares issued as part of the consideration paid for Civic was determined using the basis of the closing price of the Company’s common shares on the acquisition date. Goodwill of $9,052 arising from the acquisition consisted largely of synergies resulting from the combining of the operations of the companies. At December 31, 2019, there were no circumstances or significant changes that have occurred in 2019 related to the acquisition of Civic that, in management's assessment, would necessitate recording impairment of goodwill. The fair value of intangible assets related to core deposits was determined to be $558. The following table summarizes the consideration paid for Civic and the amounts of the assets acquired and liabilities assumed recognized at the acquisition date: Consideration: Common stock issued to Civic shareholders $ 31,635 Fair value of stock options issued to Civic option holders 1,539 Fair value of total consideration $ 33,174 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and cash equivalents $ 24,660 Certificates of deposit at other financial institutions 500 Securities available for sale 31,734 Loans 96,385 Equity securities 876 Premises and equipment 253 Core deposit intangibles 558 Foreclosed assets 350 Other assets 5,285 Total assets acquired 160,601 Deposits 123,162 Federal Home Loan Bank advances 11,500 Other liabilities 1,817 Total liabilities assumed 136,479 Total net assets acquired 24,122 Goodwill $ 9,052 The fair value of net assets acquired includes fair value adjustments to certain loan receivables that were not considered impaired as of the acquisition date. As such, these receivables were not subject to the guidance relating to purchased credit-impaired loans. Receivables acquired include loans and customer receivables with a fair value and gross contractual amounts receivable of $96,385 and $96,903, respectively, on the date of acquisition. The following table presents supplemental unaudited pro forma information as if the Civic acquisition had occurred at the beginning and 2017. The unaudited pro forma information includes adjustments for interest income on loans acquired, amortization of intangibles arising from the transaction, interest expense on deposits acquired, and the related income tax effects. The unaudited pro forma financial information is not necessarily indicative of the results of operations that would have occurred had the transactions been effected on the assumed dates. Because the Civic transaction closed on April 1, 2018, and its actual results are included in the Company’s actual operating results for the year ended December 31, 2019, there is no pro forma information for that period. For the Year Ended December 31, Unaudited 2018 2017 Net interest income – pro forma $ 106,765 $ 103,055 Net income – pro forma $ 34,606 $ 29,368 Earnings per share – pro forma: Basic $ 2.28 $ 2.09 Diluted $ 2.20 $ 1.99

SECURITIES	NOTE 3 - SECURITIES The Bank started in 2018 and continued in 2019 the planned balance sheet rotation strategy to re-deploy lower-yielding securities into higher-yielding assets. In 2019 the Bank reduced the combined securities portfolio by $500,153, or 43.4%. The following table summarizes the amortized cost and fair value of the AFS securities portfolio at December 31, 2019 and 2018 and the corresponding amounts of gross unrealized gains and losses recognized in accumulated other comprehensive loss.

At the time of transfer, the securities had an amortized cost of $117,409 and a fair value of $121,964. In 2018 there, were 16 bonds transferred under a new accounting pronouncement that, upon adoption, permitted a one-time opportunity to transfer eligible securities without affecting the status of other HTM securities. There were no HTM securities at December 31, 2019. There were no calls of HTM securities during 2019, or 2018. The amortized cost and fair value of the HTM securities portfolio at December 31, 2018 and the corresponding amounts of gross unrecognized gains and losses were as follows: Amortized Gross Gross Fair December 31, 2018 Mortgage backed securities: residential $ 75,944 $ 34 $ (3,072) $ 72,906 State and political subdivisions 45,673 466 (90) 46,049 Total $ 121,617 $ 500 $ (3,162) $ 118,955 The mortgage backed securities in which the Company has invested, both AFS and HTM, are either issued by or guaranteed by Federal Home Loan Mortgage Corporation (FHLMC), Federal National Mortgage Association (FNMA), or Government National Mortgage Association (GNMA).

As of December 31, 2019, management does not intend to sell, and it is more likely than not , that management will not be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates and other market conditions. The fair value is expected to converge to par as the bonds approach maturity. At December 31, 2019, the Company had 56 AFS securities in an unrealized loss position and no HTM securities in an unrecognized loss position compared to 163 AFS securities in an unrealized loss position and 33 HTM securities in an unrecognized loss position at December 31, 2018.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans as well as non-homogeneous residential real estate loans. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. 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 following table excludes deferred loan fees and includes PCI loans, which are included in the “Substandard” column. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows as of December 31, 2019 and 2018: Pass Special Substandard Total December 31, 2019 Construction and land development $ 591,293 $ 248 $ — $ 591,541 Commercial real estate: Nonfarm, nonresidential 941,260 997 1,764 944,021 Other 49,891 — — 49,891 Residential real estate: Closed-end 1-4 family 452,363 825 2,732 455,920 Other 185,170 — 2,511 187,681 Commercial and industrial 539,442 943 42,256 582,641 Consumer and other 4,769 — — 4,769 $ 2,764,188 $ 3,013 $ 49,263 $ 2,816,464 December 31, 2018 Construction and land development $ 580,468 $ 1,416 $ 2,556 $ 584,440 Commercial real estate: Nonfarm, nonresidential 739,469 14,774 — 754,243 Other 51,017 — — 51,017 Residential real estate: Closed-end 1-4 family 489,781 948 2,336 493,065 Other 186,485 404 2,928 189,817 Commercial and industrial 557,589 8,313 30,891 596,793 Consumer and other 5,567 1 — 5,568 $ 2,610,376 $ 25,856 $ 38,711 $ 2,674,943 At December 31, 2019, the Bank realized a $12,291 decrease in classified and criticized loans compared to December 31, 2018.

Leases [Abstract]
LEASES	LEASES Lease Arrangements The Company has entered into leases in the normal course of business primarily for real property for branches and office space with terms extending through 2034. The Company has elected not to recognize leases with original lease terms of 12 months or less (short-term leases) on the Company's balance sheet. The Company has not been reasonably certain that the Company would exercise any lease term options, and therefore, does not include lease extensions and termination options in the lease term recognized on the balance sheet. Leases are classified as operating or finance leases at the lease commencement date based on the estimated present value of lease payments over the lease term. Leases expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. The Company uses its incremental borrowing rate at lease commencement to calculate the present value of lease payments when the rate implicit in a lease is not known. The Company's incremental borrowing rate is initially based on the FHLB amortizing advance rate, adjusted for the lease term and other factors. ROU assets and lease liabilities by lease type, and the associated balance sheet classification, are as follows: Lease right-of-use assets Classification December 31, 2019 Operating leases Other Assets $ 39,594 Finance lease Other Assets 2,819 Total right-of-use assets $ 42,413 Lease liabilities Classification December 31, 2019 Operating leases Other Liabilities $ 41,308 Finance lease Other Liabilities 2,942 Total lease liabilities $ 44,250 Lease Expense Rent expense related to these leases was $5,904, $5,528 and $4,454 for 2019, 2018 and 2017, respectively. Interest expense related to the finance lease was $164 for the year ended December 31, 2019. The components of total lease cost were as follows for the period ending: Lease costs December 31, 2019 Operating lease cost $ 5,069 Variable lease cost 406 Short-term lease cost 228 Finance lease cost Interest on lease liabilities (1) 164 Amortization of right-of-use asset 201 Total lease cost $ 6,068 (1) Included in interest expense on Federal Home Loan Advances and other borrowings in the Company's consolidated statement of income. All other lease costs in this table are included in occupancy and equipment expense. Lease Obligations Future undiscounted lease payments for finance and operating leases with initial terms of one year or more as of December 31, 2019, are as follows: December 31, 2019 Finance Operating 2020 $ 276 $ 4,849 2021 280 4,871 2022 284 4,856 2023 288 4,885 2024 293 4,901 Thereafter 2,840 31,277 Total undiscounted lease payments (1) 4,261 55,639 Less: imputed interest (1,319) (14,331) Net lease liabilities $ 2,942 $ 41,308 (1) O n February 5, 2020, the Company purchased the properties at Columbia Avenue and 120 9th Avenue locations in Franklin, Tennessee, therefore ending the lease agreements. The total undiscounted operating lease payments at December 31, 2019 would be reduced by approximately $27,553 from $55,639 to $28,086 at December 31, 2019 taking in consideration these purchases.

SHARE-BASED PAYMENTS	NOTE 16 - SHARE-BASED PAYMENTS In connection with the Company’s 2010 private offering, 32,425 warrants were issued to shareholders, one warrant for every twenty shares of common stock purchased. Each warrant allowed the shareholders to purchase an additional share of common stock at $12.00 per share. The warrants were issued with an effective date of March 30, 2010 and were exercisable in whole or in part up to seven years following the date of issuance. The warrants were detachable from the common stock. The warrants expired on March 30, 2017; therefore, at December 31, 2018 and 2019, there were no outstanding warrants. The Company has two share based compensation plans as described below. Total compensation cost that has been charged against income for those plans was $5,917, $6,569, and $2,802, respectively, for 2019, 2018, and 2017. The total income tax benefit related to vesting of restricted stock and exercises of stock options was $201, $647, and $805, respectively, for 2019, 2018 and 2017. Stock Options : The Company’s 2007 Omnibus Equity Incentive Plan (the “2007 Plan”), as amended and shareholder-approved, provided for authorized shares up to 4,000,000. The 2007 Plan provided that no options intended to be incentive stock options may be granted after April 9, 2017. As a result, the Company’s Board of Directors approved, and recommended to its shareholders for approval, an equity incentive plan, the 2017 Omnibus Equity Incentive Plan which the Company’s shareholders approved at the 2017 annual meeting of shareholders. On April 12, 2018, the Company’s Board of Directors approved the Amended and Restated 2017 Omnibus Equity Incentive Plan (“Amended and Restated 2017 Plan”) to make certain changes in response to feedback received from its shareholders. The terms of the Amended and Restated 2017 Plan are substantially similar to the terms of the 2007 Plan it was intended to replace. The Amended and Restated 2017 Plan provides for authorized shares up to 3,500,000. At December 31, 2019, there were 2,410,486 authorized shares available for issuance under the Amended and Restated 2017 Plan. Employee, organizer and director awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant; those option awards have a vesting period of two ten The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected stock price volatility is based on historical volatilities of the Company’s common stock. The Company uses historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The fair value of options granted was determined using the following weighted-average assumptions as of grant date. 2019 2018 2017 Risk-free interest rate 1.68 % 3.10 % 2.05 % Expected term 7 years 7.5 years 6.9 years Expected stock price volatility 29.73 % 30.79 % 33.21 % Dividend yield 0.60 % — % 0.03 % The weighted average fair value of options granted for the years ended December 31, 2019, 2018 and 2017 was $9.68, $11.50, and $14.43, respectively. A summary of the activity with respect to stock options for the years ended December 31, 2019, 2018 and 2017 follows: Shares Weighted Weighted Aggregate Outstanding at January 1, 2017 1,395,016 $ 16.70 Granted 295,820 37.68 Exercised (180,555) 11.87 Forfeited, expired, or cancelled (3,113) 25.37 Outstanding at December 31, 2017 1,507,168 $ 21.37 Granted 572,637 30.48 Exercised (244,309) 16.83 Forfeited, expired, or cancelled (27,574) 28.66 Outstanding at December 31, 2018 1,807,922 $ 24.68 Granted 102,930 27.86 Exercised (326,818) 17.87 Forfeited, expired, or cancelled (84,464) 33.64 Outstanding at December 31, 2019 1,499,570 $ 22.39 6.46 $ 12,676 Vested or expected to vest 1,424,592 $ 25.88 5.85 $ 12,042 Exercisable at December 31, 2019 832,993 $ 19.62 5.85 $ 12,251 2019 2018 2017 Stock options exercised: Intrinsic value of options exercised $ 4,268 $ 4,873 $ 4,878 Cash received from options exercised 5,307 3,047 1,615 Tax benefit realized from option exercises 86 565 484 As of December 31, 2019, there was $3,439 of total unrecognized compensation cost related to non-vested stock options granted under the Plan.

Restricted Stock and Restricted Stock Units : Additionally, the Company’s 2007 Plan and the Amended and Restated 2017 Plan each provides for the granting of restricted share awards and other performance related incentives. When restricted shares are awarded, a participant receives voting and dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. In April 2019, the Company began awarding restricted stock units which participants do not have voting rights or dividend rights until the restrictions have lapsed. These awards typically have a vesting period of three A summary of activity for non-vested restricted share awards for the year ended December 31, 2019, 2018 and 2017 is as follows: Non-vested Shares Shares Weighted- Non-vested at January 1, 2017 106,458 $ 19.81 Granted 27,282 37.35 Vested (38,995) 18.40 Forfeited (564) 28.66 Non-vested at December 31, 2017 94,181 $ 25.42 Granted 126,288 33.04 Vested (40,134) 26.69 Forfeited (3,819) 31.80 Non-vested at December 31, 2018 176,516 $ 31.07 Granted 1,255 31.87 Vested (85,151) 29.51 Forfeited (1,628) 31.42 Non-vested at December 31, 2019 90,992 $ 32.54 Compensation expense associated with the restricted share awards is recognized on a straight-line basis over the time period that the restrictions associated with the awards lapse based on the total cost of the award at the grant date. As of December 31, 2019, there was $1,093 of total unrecognized compensation cost related to non-vested shares granted under the 2007 Plan and Amended and Restated 2017 Plan. The cost is expected to be recognized over a weighted-average period of 0.7 years. The total fair value of shares vested during the years ended December 31, 2019, 2018 and 2017 was $2,395, $1,382, and $1,432, respectively. The Company began granting restricted stock units in 2019.

There was no expense related to restricted stock units in 2018. This stock compensation is recognized on a straight-line basis over the time period that the restrictions associated with the awards lapse based on the total cost of the award at the grant date. As of December 31, 2019, there was $3,099 of total unrecognized compensation expense related to non-vested units granted under the 2007 Plan and Amended and Restated 2017 Plan.

Banking and Thrift [Abstract]
REGULATORY CAPITAL MATTERS	NOTE 17 – REGULATORY CAPITAL MATTERS Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. Banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Management believes that, as of December 31, 2019, the Company and Bank meet all capital adequacy requirements to which they are subject. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. Banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization must hold a capital conservation buffer composed of Common Equity Tier 1 Capital above its minimum risk-based capital requirements. The buffer is measured relative to RWA. Phase-in of the capital conservation buffer requirements began on January 1, 2016 and the requirements were fully phased in on January 1, 2019. The capital conservation buffer threshold for 2019 was 2.5%. A banking organization with a buffer greater than 2.5% will not be subject to limits on capital distributions or discretionary bonus payments; however, a banking organization with a buffer of less than 2.5% will be subject to increasingly stringent limitations as the buffer approaches zero. The rule also prohibits a banking organization from making distributions or discretionary bonus payments during any quarter if its eligible retained income is negative in that quarter and its capital conservation buffer ratio was less than 2.5% at the beginning of the quarter. Effectively, the Basel III framework will require us to meet minimum capital ratios of (i) 7% for Common Equity Tier 1 Capital, (ii) 8.5% Tier 1 Capital, and (iii) 10.5% Total Capital. The eligible retained income of a banking organization is defined as its net income for the four calendar quarters preceding the current calendar quarter, based on the organization’s quarterly regulatory reports, net of any distributions and associated tax effects not already reflected in net income. Now that the new rule is fully phased in, the minimum capital requirements plus the capital conservation buffer will exceed the prompt corrective action (“PCA”) well-capitalized thresholds. PCA regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At December 31, 2019, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. Actual and required capital amounts and ratios are presented below as of December 31, 2019 and 2018 for the Company and Bank.

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 18 - FAIR VALUE Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Assets and liabilities measured at fair value on a recurring basis, including financial assets and liabilities for which the Company has elected the fair value option, are summarized below: Fair Value Measurements at December 31, 2019 Using: Quoted Prices Significant Significant Mortgage-backed securities: residential $ — $ 375,943 $ — Mortgage-backed securities: commercial — 17,780 — Corporate Notes — 33,361 — State and political subdivisions — 225,048 — Total securities available for sale $ — $ 652,132 $ — Loans held for sale $ — $ 43,162 $ — Other assets $ — $ 225 $ — Liabilities Other liabilities $ — $ 73 $ — Fair Value Measurements at December 31, 2018 Using: Quoted Prices Significant Significant Assets U.S. Treasury $ 253,014 $ — $ — U.S. government sponsored entities and agencies — 21,888 — Mortgage-backed securities: residential — 580,699 — Mortgage-backed securities: commercial — 24,844 — Corporate Notes — 12,424 — State and political subdivisions — 137,799 — Total securities available for sale $ 253,014 $ 777,654 $ — Loans held for sale $ — $ 11,103 $ — Other assets $ — $ 206 $ — Liabilities Other liabilities $ — $ 129 $ — The Company used the following methods and significant assumptions to estimate the fair value of financial instruments that are measured at fair value on a recurring basis: Securities : The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). Other assets : Included in other assets are certain assets carried at fair value and interest rate locks associated with the mortgage loan pipeline. The fair value of the mortgage loan pipeline rate locks is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate. These assets are valued using similar observable data that occurs in the market (Level 2) Loans Held For Sale: These loans are typically sold to an investor following loan origination and the fair value of such accounts are readily available based on direct quotes from investors or similar transactions experienced in the secondary loan market. Fair value adjustments, as well as realized gains and losses are recorded in current earnings. Fair value is determined by market prices or similar transactions adjusted for specific attributes of that loan (Level 2). Other Liabilities : The Company has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions, and the cash flow hedge and interest rate locks associated with the funding for its mortgage loan originations. The fair value of these liabilities is based on pricing models that utilize observable market inputs (Level 2). There were no transfers between levels for the years ended December 31, 2019 and 2018. The following table presents assets measured at fair value on a non-recurring basis. There were no liabilities measured at fair value on a non-recurring basis as December 31, 2019 and 2018. Total carrying value in the Quoted market prices in Models with significant Models with significant Total losses for the period ended December 31, 2019 Impaired loans, net: (1) Residential real estate: Closed-end 1-4 family $ 626 $ — $ — $ 626 $ — Commercial and industrial 3,763 — 3,650 113 — Total $ 4,389 $ — $ 3,650 $ 739 $ — December 31, 2018 Impaired loans, net (1) Commercial and industrial $ 150 $ — $ — $ 150 $ — (1) Amount is net of a valuation allowance of $20,771 and $17 at December 31, 2019 and 2018, respectively, as required by ASC 310-10, "Receivables." As of December 31, 2019 and 2018, the only Level 3 assets with material unobservable inputs are associated with impaired loans. The table above includes those loans that are impaired and have a carrying balance as of December 31, 2019, and 2018. Impaired Loans : A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due pursuant to the contractual terms of the loan agreement. Impairment is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan's collateral. For real estate loans, fair value of the impaired loan's collateral is determined by third party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically is 10% of the appraised value. For non-real estate collateral loans, the unobservable inputs will vary depending on the credit. The fair value of the impaired loan's collateral may be determined using a third party appraisal, transactional values, discounted cash flows (DCF), sales comparisons, asset value, or aging reports, adjusted or discounted. As of December 31, 2019 the fair value of the non-real estate collateral loans was determined primarily based on the transactional value, resulting in a Level 2 fair value classification. Foreclosed Assets : Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Foreclosed assets are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the credit administration department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. On an annual basis, the Company compares the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value. The Company measures certain assets at fair value on a non-recurring basis including impaired loans (excluding PCI loans), loans held for sale, and OREO. These fair value adjustments result from impairments recognized during the period, application of the lower of cost or fair value on loans held for sale, and the application of fair value less cost to sell on OREO. The following tables present valuation techniques and unobservable inputs for assets measured at fair value on a non-recurring basis for which the Company has utilized Level 3 inputs to determine fair values at December 31, 2019 and 2018: Financial Instruments Recorded Using Fair Value Option At December 31, 2019, the unpaid principal balance of loans held for sale was $42,152, resulting in an unrealized gain of $1,010 included in gains on sale of loans. None of these loans are 90 days or more past due or on nonaccrual as of December 31, 2019. At December 31, 2018, the unpaid principal balance of loans held for sale was $10,722, resulting in an unrealized gain of $381 included in mortgage banking revenue.

At December 31 2018, there was one collateral dependent impaired loan carried at fair value of $150 resulting in an additional provision for loan losses of $17 recorded related to impaired loans recorded at fair value of collateral. There were no foreclosed assets as of December 31, 2019 and 2018, and accordingly, there were no properties at December 31, 2019 and 2018 that required write-downs to fair value resulting in no write downs for the years ended December 31, 2019 and 2018. The Company measures certain assets at fair value on a non-recurring basis including impaired loans (excluding PCI loans), loans held for sale, and OREO. These fair value adjustments result from impairments recognized during the period, and the application of fair value less cost to sell on OREO. The following tables present valuation techniques and unobservable inputs for assets measured at fair value on a non-recurring basis for which the Company has utilized Level 3 inputs to determine fair values at December 31, 2019 and 2018: The carrying amounts and estimated fair values of financial instruments, at December 31, 2019 and 2018 are as in the tables below. The methods and assumptions not previously described used to estimate fair values are described as follows: (a) Cash and Cash Equivalents: The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. (b) Loans: Fair values of loans, excluding loans held for sale, are estimated as follows: In accordance with ASU 2016-01, the fair value of loans held for investment, is estimated using a cash flow projection methodology that relies on three primary assumptions: (1) the expected prepayment rate of loans; (2) the magnitude of future net losses based on expected default rate and severity of loss; and (3) the discount rate applicable to the expected cash flows of the loan portfolio. Loans are considered a Level 3 classification. (c) Mortgage Servicing Rights: Fair value of mortgage servicing rights is based on valuation models that calculate the present value of estimated net cash flows based on industry market data. The valuation model incorporates assumptions that market participants would use in estimating future net cash flows resulting in a Level 3 classification. (d) Deposits: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 1 classification. The carrying amounts of fixed-term money market accounts approximate their fair values at the reporting date resulting in a Level 1 classification. Fair values for certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (e) Federal Funds Purchased and Repurchase Agreements: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification. (f) Federal Home Loan Bank Advances: The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. (g) Subordinated Notes: The fair values of the Company's subordinated notes are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. (h) Accrued Interest Receivable/Payable: The carrying amounts of accrued interest approximate fair value resulting in a Level 1, Level 2 or Level 3 classification based on the asset/liability with which they are associated. (i) Off-balance Sheet Instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	NOTE 19 – DERIVATIVES The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as hedges, the gain or loss is recognized in current earnings. Derivatives Designated as Fair Value Hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. During 2019, the Company entered into 16 swap transactions with a notional amount of $101,205 designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate securities. A summary of the Company's fair value hedge relationships as of December 31, 2019 are as follows (in thousands): December 31, 2019 December 31, 2018 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Estimated Notional Estimated Liability derivatives Interest rate swap agreements - securities Other Liabilities 7.32 2.53 % 3 month LIBOR $ 101,205 $ 4,954 $ — $ — The effects of fair value hedge relationships reported in interest income on securities on the consolidated statements of income for the twelve months ended December 31, 2019 and 2018 were as follows (in thousands): Amount of Gain Recognized in Income Location of Gain on Hedged Item Twelve months ended December 31, 2019 2018 Liability derivatives Interest rate swap agreements - securities Interest Income $ 4,954 $ — Amount of Loss Recognized in Income Location of Loss on Derivative Twelve months ended December 31, 2019 2018 Liability derivatives Interest rate swap agreements - securities Interest Income $ (4,954) $ — The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges at December 31, 2019: Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets December 31, 2019 December 31, 2018 December 31, 2019 December 31, 2018 Line item on the balance sheet Securities available-for-sale $ 101,205 $ — $ 4,954 $ — Derivatives Designated as Cash Flow Hedges For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. The Company uses cash flow hedge relationships in an effort to manage future interest rate exposure. The hedging strategy converts the LIBOR-based variable interest rate on forecasted borrowings to a fixed interest rate and is used in an effort to protect the Company from floating interest rate variability. A summary of the Company's cash flow hedge relationships as of December 31, 2019 are as follows (in thousands): December 31, 2019 December 31, 2018 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Estimated Notional Estimated Liability derivatives Interest rate swap agreements Deposits 2.34 2.23 % 1 month LIBOR $ 100,000 $ 1,592 $ — $ — There were no cash flow hedge relationships as of December 31, 2018.

If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive (loss) income would be reclassified into a line item within the statement of income that impacts operating results. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or the Company discontinues hedge accounting. The Company expects the hedges to continue to be highly effective and qualify for hedge accounting during the remaining terms of the swaps. Mortgage Banking Derivatives Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not designated as hedge relationships. At year-end 2019, the Company had approximately $48,999 of interest rate lock commitments and approximately $62,824 of forward commitments for the future delivery of residential mortgage loans. The fair value of these mortgage banking derivatives was reflected by a derivative asset and liability of $225 and $73, respectively, at December 31, 2019. At year-end 2018, the Company had approximately $28,731 of interest rate lock commitments and approximately $31,519 of forward commitments for the future delivery of residential mortgage loans. The fair value of these mortgage banking derivatives was reflected by a derivative asset and liability of $206 and $129, respectively, at December 31, 2018. Fair values were estimated based on changes in mortgage interest rates from the date of the commitments. Changes in the fair values of these mortgage-banking derivatives are included in mortgage banking revenue. The net gains (losses) relating to free-standing derivative instruments used for risk management is summarized below: 2019 2018 2017 Forward contracts related to mortgage loans held for sale and interest rate contracts $ 56 $ 94 $ 32 Interest rate contracts for customers 19 31 (54) The following table reflects the amount and fair value of mortgage banking derivatives included in the consolidated balance sheet as of December 31, 2019 and 2018: 2019 2018 Notional Fair Notional Fair Included in other assets (liabilities): Interest rate contracts for customers $ 48,999 $ 225 $ 28,731 $ 206 Forward contracts related to mortgage loans held for sale $ 62,824 $ (73) $ 31,519 $ (129)

Loan Commitments And Other Related Activities [Abstract]
LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES	NOTE 20 – LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance-sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment. The contractual amounts of financial instruments with off-balance-sheet risk at year end were as follows: 2019 2018 Fixed Variable Fixed Variable Commitments to make loans $ 48,999 $ — $ 28,731 $ — Unused lines of credit 89,040 701,326 128,313 526,271 Standby letters of credit 7,119 48,750 8,293 31,731 Commitments to make loans are generally made for periods of over 365 days. The fixed rate loan commitments have interest rates ranging from 2.82% to 12.00% and maturity terms ranging from less than 1 year to 25 years.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	NOTE 22 – EARNINGS PER SHARE The two-class method is used in the calculation of basic and diluted earnings per share. Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings. The factors used in the earnings per share computation follow: Year Ended December 31, 2019 2018 2017 Basic Net income available to common shareholders $ 14,806 $ 34,505 $ 28,083 Less: earnings allocated to participating securities (120) (372) (219) Net income allocated to common shareholders $ 14,686 $ 34,133 $ 27,864 Weighted average common shares outstanding including participating securities $ 14,633,399 $ 14,169,294 $ 13,145,005 Less: Participating securities (118,747) (152,638) (102,650) Average shares 14,514,652 14,016,656 13,042,355 Basic earnings per common share $ 1.01 $ 2.44 $ 2.14 Diluted Net income allocated to common shareholders $ 14,686 $ 34,133 $ 27,864 Weighted average common shares outstanding for basic earnings per common share 14,514,652 14,016,656 13,042,355 Add: Dilutive effects of assumed exercises of stock options 352,242 540,302 633,738 Add: Dilutive effects of assumed exercises of stock warrants — — 1,578 Add: Dilutive effects of assumed vesting of restricted stock units 95,413 $ — $ — Average shares and dilutive potential common shares $ 14,962,307 $ 14,556,958 $ 13,677,671 Dilutive earnings per common share $ 0.98 $ 2.34 $ 2.04 Average stock options of 876,086, 546,325, and 285,706 shares of common stock were not considered in computing diluted earnings per common share for the year ended December 31, 2019, 2018, and 2017, respectively, because they were antidilutive.

Accounting Policies [Abstract]
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation : The consolidated financial statements include Franklin Financial Network, Inc. ("FFN") and its wholly-owned subsidiaries, Franklin Synergy Bank (the “Bank”) and Franklin Synergy Risk Management, Inc., together referred to as “the Company.” Intercompany transactions and balances are eliminated in consolidation. The Company was incorporated under the laws of the State of Tennessee on April 5, 2007. The Bank was incorporated under the laws of the State of Tennessee and received its Certificate of Authority from the Tennessee Department of Financial Institutions and approval of Federal Deposit Insurance Corporation (FDIC) insurance on November 2, 2007. The Bank is also a Federal Reserve member bank. The Company provides financial services through its offices in Franklin, Brentwood, Spring Hill, Murfreesboro, Nashville, Nolensville, and Smyrna, Tennessee. Its primary deposit products are checking, savings, and certificate of deposit accounts, and its primary lending products are commercial and residential construction, commercial, installment loans and lines secured by home equity. Substantially all loans are secured by specific items of collateral including commercial and residential real estate, business assets, and consumer assets. Commercial loans are expected to be repaid by cash flow from operations of businesses. The Company also focuses on electronic banking products such as internet banking, remote deposit capture and lockbox services. On July 1, 2014, Mid-South Bancorp (“Mid-South”) merged into the Bank with the Bank continuing as the surviving company. On December 28, 2015, the Company invested in a wholly-owned subsidiary, FSRM, which provides risk management services to the Company in the form of enhanced insurance coverages. On March 1, 2016, the Bank invested in a wholly-owned subsidiary, Franklin Synergy Investments of Tennessee, Inc. (“FSIT”), which provides investment services to the Bank. Also on March 1, 2016, FSIT invested in a wholly-owned subsidiary, Franklin Synergy Investments of Nevada, Inc. (“FSIN”), to provide investment services to FSIT. In addition, on March 1, 2016, FSIN invested in a subsidiary, Franklin Synergy Preferred Capital, Inc. (“FSPC”), to serve as a real estate investment trust (“REIT”), to allow the Bank to sell real estate loans to the REIT to obtain a tax benefit. FSIN has a controlling interest in the REIT, but the REIT also has a group of investors that own a noncontrolling interest in the preferred stock of the REIT. On April 1, 2018, Civic Bank & Trust merged with and into the Bank with the Bank continuing as the surviving company. See Note 2 in the notes of the consolidated financial statements. On January 21, 2020, FFN, FB Financial Corporation, a Tennessee corporation (“FB Financial”), and Paisley Acquisition Corporation, a Tennessee corporation and a direct, wholly-owned subsidiary of FB Financial (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which, on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into FFN, with FFN continuing as the surviving corporation (the “Merger”). Immediately following the Merger, FFN will merge with and into FB Financial, with FB Financial continuing as the surviving corporation (the “Upstream Merger”). Immediately following the Upstream Merger, FSB will merge with and into FirstBank, a Tennessee state-chartered bank and a wholly owned subsidiary of FB Financial (“FirstBank”), with FirstBank continuing as the surviving bank (the “Bank Merger,” and, together with the Merger and the Upstream Merger, the “Mergers”). Under the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of the common stock, no par value (the “FFN Common Stock”), issued and outstanding immediately prior to the Effective Time (except for certain shares of FFN Common Stock owned by FFN as treasury stock or by FB Financial, as provided in the Merger Agreement) will be converted, in accordance with the procedures set forth in the Merger Agreement, into the right to receive, without interest, (1) 0.9650 shares (the “Exchange Ratio”) of common stock, par value $1.00 per share, of FB Financial (“FB Financial Common Stock”) and (2) $2.00 in cash (the “Per Share Cash Consideration” and, collectively with the FB Financial Common Stock to be issued pursuant to the preceding clause (1), the “Merger Consideration”). The completion of the Mergers is subject to customary conditions, including (i) receipt of FFN shareholder approval and FB Financial shareholder approval, (ii) authorization for listing on the New York Stock Exchange of the shares of FB Financial Common Stock to be issued in the Merger, (iii) the receipt of required regulatory approvals, including the approval of the Federal Reserve Board, the Federal Deposit Insurance Corporation and the Tennessee Department of Financial Institutions, (iv) effectiveness of the registration statement on Form S-4 for the FB Financial Common Stock to be issued in the Merger, and (v) the absence of any order, injunction or other legal restraint preventing or making illegal the completion of the Merger or any of the other transactions contemplated by the Merger Agreement.
Use of Estimates	Use of Estimates : To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Cash Flows	Cash Flows : Cash and cash equivalents include cash, deposits with other financial institutions with maturities under 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions and federal funds purchased.
Interest-Bearing Deposits in Financial Institutions	Interest-Bearing Deposits in Financial Institutions : Interest-bearing deposits in other financial institutions are carried at cost.
Securities	Securities : Debt securities were classified as held to maturity (HTM) and carried at amortized cost when management had the positive intent and ability to hold them to maturity. Debt securities are classified as available for sale (AFS) when they might be sold before maturity. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Management assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of these criteria is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. No OTTI has been recognized for the years ended December 31, 2019, 2018 or 2017.
Loans Held for Sale	Loans Held for Sale : Loans originated and intended for sale in the secondary market are carried at fair value as of the balance sheet date as determined by outstanding commitments from investors and includes the servicing value of the loans. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Certain loans held for sale are sold with servicing rights retained. The carrying value of loans sold with retained servicing is reduced by the amount allocated to the servicing right. Gains and losses on sales of loans are based on the difference between the selling price and the carrying value of the related loan sold.
Loans	Loans : Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of purchase discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income on mortgage loans and loans held for investment is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. A loan is moved to non-accrual status in accordance with the Company’s policy, typically after 90 days of non-payment. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The banking agencies define a “Shared National Credit” (“SNC”) as any loan extended to a borrower which aggregates $100 million or more and is shared by three or more banks. The SNC portfolio totaled $136,658 at December 31, 2019, decreasing 45.1% from $249,033 at December 31, 2018, driven by the sales and paydowns of $112,375 of SNCs during 2019. The entire outstanding balance of SNCs was included in the commercial and industrial portfolio. To meet the needs of our customers, SNC participations are entered into during the normal course of business and are reviewed at least quarterly for credit quality.
Concentration of Credit Risk	Concentration of Credit Risk : Most of the Company’s business activity is with customers located within Williamson County, Davidson County, and Rutherford County; therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy in the Williamson County, Davidson County, and Rutherford County areas. The Company believes there are no significant concentrations of loans to any one industry or customer. However, the customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area.
Purchased Credit Impaired (PCI) Loans	Purchased Credit Impaired (PCI) Loans : The Company purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination. The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s or pool’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.
Allowance for Loan Losses	Allowance for Loan Losses : The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDRs) and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. All loans classified by management as substandard or worse are individually evaluated for potential designation as impaired. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. TDRs are individually evaluated for impairment disclosures and included in the separately identified impairment disclosures. TDRs are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. TDRs are subsequently tracked and reviewed for impairment quarterly. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on a combination of the Bank’s loss history and loss history over the past three years from a group of other local banks that operate in the Middle Tennessee areas. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: • Construction and land development loans include loans to finance the process of improving, preparatory or erecting new structures or the on-site construction of industrial, commercial, residential or farm buildings. Construction and land development loans also include loans secured by vacant land, except land known to be used or usable for agricultural purposes. Construction loans generally are made for relatively short terms. They generally are more vulnerable to changes in economic conditions. Further, the nature of these loans is such that they are more difficult to evaluate and monitor. The risk of loss on a construction loan is dependent largely upon the accuracy of the initial estimate of the property’s value upon completion of the project and the estimated cost (including interest) of the project. Periodic site inspections are made on construction loans. • Commercial real estate loans include loans secured by non-residential real estate, including farmland and improvements thereon. Often these loans are made to single borrowers or groups of related borrowers, and the repayment of these loans largely depends on the results of operations and management of these properties. Adverse economic conditions may affect the repayment ability of these loans. • Residential real estate loans include loans secured by residential real estate, including single-family and multi-family dwellings. Mortgage title insurance and hazard insurance are normally required. Adverse economic conditions in the Company’s market area may reduce borrowers’ ability to repay these loans and may reduce the collateral securing these loans. • Commercial and industrial loans include loans for commercial, industrial, healthcare or agricultural purposes to business enterprises that are not secured by real estate. Commercial loans are typically made on the basis of the borrower’s ability to repay from the cash flow of the borrower’s business. Commercial and Agriculture loans are generally secured by accounts receivable, inventory and equipment. The collateral securing loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. • Consumer and other loans include loans to individuals for household, family and other personal expenditures that are not secured by real estate. Consumer loans are generally secured by customer deposit accounts, vehicles and other household goods. The collateral securing consumer loans may depreciate over time.
Servicing Rights	Servicing Rights : When loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in gain on sale of loans. Fair value is based on market prices for comparable servicing contracts. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with loan servicing fees on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
Transfers of Financial Assets	Transfers of Financial Assets : Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Foreclosed Assets	Foreclosed Assets : Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.
Premises and Equipment	Premises and Equipment : Premises and equipment are stated at cost less accumulated depreciation and are depreciated using the straight-line method. Depreciation periods are shorter of the asset’s useful life or lease period, ranging from three
Restricted Equity Securities	Restricted Equity Securities : The Bank is a member of the Federal Reserve Bank (FRB) and the FHLB system. Members of the FRB and FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. The stock ownership in FRB and FHLB are carried at cost, classified as restricted securities, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Company Owned Life Insurance/Bank Owned Life Insurance	Company Owned Life Insurance/Bank Owned Life Insurance : The Company and the Bank have purchased life insurance policies on certain key executives. Company owned life insurance/bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets : Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the balance sheet. Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from whole bank and branch acquisitions are amortized on an accelerated method over their estimated useful lives, which range from 7 to 10 years.
Long-Term Assets	Long-Term Assets : Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments : Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Mortgage Banking Derivatives	Mortgage Banking Derivatives : Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitment before the loan is funded. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest rate on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives are included in net gains on sale of mortgage loans. Derivatives : At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company's intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment ("fair value hedge"), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow hedge"), or (3) as instrument with no hedging designation ("stand-alone derivative"). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedged accounting are reported currently in earnings, as noninterest income. Net settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows on the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or forecasted transactions. The Company also formally assesses, both at the hedge's inception and on an ongoing bases, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted traction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Stock-Based Compensation	Stock-Based Compensation : Compensation cost is recognized for stock options and restricted stock awards based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period, reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. All excess tax benefits and tax deficiencies related to share-based payment awards are recognized as income tax expense or benefit in the income statement during the period in which they occur.
Income Taxes	Income Taxes : Income tax expense or benefit is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. Accordingly, deferred tax assets that were realized after December 31, 2017 were remeasured using the tax rates enacted as a result of the 2017 Tax Cuts and Jobs Act resulting in an additional income tax expense of $5,323 as of December 31, 2017. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. 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% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.
Retirement Plans	Retirement Plans : Employee 401(k) and profit sharing plan expense is the amount of matching contributions. The matching contributions are paid with employer stock.
Comprehensive Income	Comprehensive Income (Loss): Comprehensive income (loss) consists of the total of all components of comprehensive income (loss) including net income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive income (loss) but excluded from net income (loss). Currently, the Company's other comprehensive income (loss) consists primarily of unrealized gains and losses on securities available for sale, net of deferred tax expense (benefit) and unrealized gains (losses) on derivative hedging relations.
Earnings Per Common Share	Earnings Per Common Share : Basic earnings per common share is net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options and warrants.
Loss Contingencies	Loss Contingencies : Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.
Restrictions on Cash	Restrictions on Cash : Cash on hand or on deposit with the Federal Reserve Bank was required to meet regulatory reserve and clearing requirements.
Dividend Restriction	Dividend Restriction : Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders.
Fair Value of Financial Instruments	Fair Value of Financial Instruments : Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Operating Segments	Operating Segments : While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassifications	Reclassifications: Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or equity.
Adoption of New Accounting Standards	Adopted New Accounting Standards: In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, "Leases (topic 842)." ASU 2016-02, Leases which requires the Company as lessees to recognition in the statement of financial position lease assets and lease liabilities for those leases classified as operating leases under previous GAAP. On January 1, 2019, the Company adopted ASU 2016-02, and subsequent amendments thereto, which requires the Company to recognize most leases on the balance sheet. We adopted the standard under a modified retrospective approach as of the date of adoption and elected to apply several of the available practical expedients, including: • Carry over of historical lease determination and lease classification conclusions • Carry over of historical initial direct cost balances for existing leases • Accounting for lease and non-lease components in contracts in which the Company is a lessee as a single lease component Adoption of the leasing standard resulted in the recognition of operating right-of-use assets and operating lease liabilities of $43,723, as of January 1, 2019. These amounts were determined based on the present value of remaining minimum lease payments, discounted using the Company's incremental borrowing rate as as of the date of adoption. Prior periods were not restated and continue to be presented under legacy GAAP. Disclosures about the Company's leasing activities are presented in Note 7 - Leases. In March 2017, the FASB issued ASU 2017-08, " Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities ." These amendments shorten the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance became effective for the Company on January 1, 2019, and using a modified retrospective transition adoption approach, we recognized a cumulative effect reduction to retained earnings totaling $2,244. In October 2018, the FASB issued ASU 2018-16 , “Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” This update expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on the SOFR. Due to concerns about the sustainability of the London Interbank Offered Rate (“LIBOR”), a committee convened by the Federal Reserve Board and the Federal Reserve Bank of New York initiated an effort to introduce an alternative reference rate in the U.S. The committee identified SOFR as the preferred alternative reference rate to LIBOR. The OIS rate based on SOFR was added as a U.S. benchmark interest rate to facilitate broader use in the marketplace and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies. The Company adopted the provisions of ASU 2018-16 on January 1, 2019, and it did not have a material impact on our consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June 2016, FASB issued ASU 2016-13 , " Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, " (CECL) which replaces the existing incurred loss impairment methodology for loans that are collectively evaluated for impairment with a methodology that reflects management’s best estimate of lifetime expected credit losses and requires consideration of reasonable and supportable economic forecasts to develop a lifetime credit loss estimate. Topic 326 requires additional qualitative and quantitative disclosure to allow users to better understand the credit risk within the portfolio and the methodologies for determining the allowance for credit losses. The CECL standard also simplifies the accounting model for purchased credit impaired loans. Franklin Synergy will adopt Topic 326 effective January 1, 2020 using the modified retrospective approach. Our methodology for estimating lifetime expected credit losses for our loan portfolios will include the following key components: a. Segmentation of loans into pools that share common risk characteristics; b. An economic forecast period based on the relation of losses with key economic variables for each portfolio segment; c. Reversion period to historical loss experience using straight-line method; d. Inclusion of qualitative adjustments to consider factors that have not been accounted for; e. Discounted cash flow (DCF) method to measure credit impairment on each of our loan portfolio segments; f. Credit losses for loans that do not share similar risk characteristics are estimated on an individual basis. The lifetime losses for individually measured loans are estimated based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows. g. The estimation methodology for credit losses on unfunded lending-related commitments is similar to the process for estimating credit losses for loans, although with the addition of a probability of draw estimate that is applied to each loan portfolio segment. As part of our evaluation of the estimated impacts of CECL, we have run simulations based on our portfolio composition and current expectations of future economic conditions. The ultimate effect of CECL on our allowance for credit losses (ACL) will depend the portfolio’s credit quality and economic conditions at the time of adoption. The Company’s CECL implementation efforts are in process and continue to focus on model validation, refinement of the model assumptions, the qualitative factor, and the operational control framework to support the new process. During the first quarter of 2020, we expect all internal reviews of the adjustments to be finalized, and all processes and controls surrounding the ongoing estimate to be fully implemented and documented. At adoption, we expect to have a cumulative-effect adjustment to retained earnings for this change in the ACL, which would impact our capital. Franklin Synergy expects to continue to be well capitalized under the Basel III regulatory framework after the adoption of this standard. Franklin Synergy will avail itself of the option to phase-in over a period of three years the day one effects on regulatory capital from the adoption of CECL. For PCD loans, including Civic acquired book, the adjustment will be made through the allowance and loan balances with no impact in capital. Topic 326 also requires expected credit losses on available-for-sale (AFS) debt securities be recorded as an allowance for credit losses. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may expect zero credit losses. Franklin Synergy estimates that the adoption of this standard on January 1, 2020 will not have a material impact on our portfolio of AFS debt securities. In January 2017, the FASB issued ASU 2017-04, " Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," to simplify how entities other than private companies, such as public business entities and not-for-profit entities, are required to test goodwill for impairment by eliminating the comparison of the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. ASU 2017-04 is effective for us on January 1, 2020. The impact of this standard will depend on the market conditions at the time of the assessment date. In August 2018, the FASB issued ASU 2018-13 , “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 only revises disclosure requirements and will not have a significant impact on our financial statements. The amendment is effective for us on January 1, 2020. In August 2018, the FASB issued ASU 2018-14 , "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)." ASU 2018-14 amends and modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The amendments in this update remove disclosure that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. ASU 2018-14 will be effective for us on January 1, 2021, with early adoption permitted, and is not expected to have a significant impact on our financial statements. In August 2018, the FASB issued ASU 2018-15, “ Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. ” ASU 2018-15 clarifies certain aspects of ASU 2015-05, “ Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, ” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract. ASU 2018-15 is effective for us on January 1, 2020, and is not expected to have a significant impact on our financial statements. In December 2019, the FASB issued ASU 2019-12 , "Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes ." The guidance issued in this update simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition for deferred tax liabilities for outside basis differences. ASU 2019-12 also simplifies aspects of the accounting for franchise taxes, enacted changes in tax laws for rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 will be effective for us on January 1, 2021, with early adoption permitted. The Company is currently evaluating the impact on its results of operations, financial position, and liquidity. Other than those pronouncements discussed above and those which have been recently implemented, we do not believe there were any other recently issued accounting pronouncement that are expected to materially impact the Company.
Derivatives	The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as hedges, the gain or loss is recognized in current earnings.For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. The Company uses cash flow hedge relationships in an effort to manage future interest rate exposure. The hedging strategy converts the LIBOR-based variable interest rate on forecasted borrowings to a fixed interest rate and is used in an effort to protect the Company from floating interest rate variability. Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not designated as hedge relationships
