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 to fifteen years. 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 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, 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: Cash on hand or on deposit with the Federal Reserve Bank was required to meet regulatory reserve and clearing requirements. 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 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: 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: 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. Recently 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.
