The fair value is expected to recover as the bonds approach maturity.

A portion of the fair value discount has been recognized as an accretable yield that is accreted into interest income over the estimated remaining life of the loans. The remaining non-accretable difference represents cash flows not expected to be collected. The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and carrying value of the loans as of March 31, 2016 and December 31, 2015.

Share-Based Payments	NOTE 6—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 allows 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 will be exercisable in whole or in part up to seven years following the date of issuance. The warrants are detachable from the common stock. There were 3,150 and 200 warrants exercised during the three months ended March 31, 2016 and 2015, respectively. A summary of the stock warrant activity for the three months ended March 31, 2016 and 2015 follows: 2016 2015 Stock warrants exercised: Intrinsic value of warrants exercised $ 61 $ 2 Cash received from warrants exercised 38 2 At March 31, 2016, there 22,157 outstanding warrants associated with the 2010 offering. Since the common stock of the Company is registered under the Securities Act and has been traded on a national securities exchange at $15.00 or more for forty-five (45) consecutive days, the Company may redeem the 2010 warrants at any time with not less than thirty (30) days’ written notice to the holders of such 2010 warrants, in whole or in part, at a redemption price of $1.00 per warrant; provided, however, that the holder of the 2010 warrant may exercise the 2010 warrant, in whole or in part, during such thirty (30) day period. The Company has two share based compensation plans as described below. Total compensation cost that has been charged against income for those plans was $258 and $146 for the three months ended March 31, 2016 and 2015, respectively. The total income tax benefit was $147 for the three months ended March 31, 2015. There was no excess tax benefit from the exercise of stock options for the three months ended March 31, 2016. Stock Option 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 three to five years and have a ten-year contractual term. The Company assigns discretion to its Board of Directors to make grants either as qualified incentive stock options or as non-qualified stock options. All employee grants are intended to be treated as qualified incentive stock options, if allowable. All other grants are expected to be treated as non-qualified. 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 a peer group. 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. March 31, March 31, Risk-free interest rate 1.99 % 1.93 % Expected term 7.5 years 7.5 years Expected stock price volatility 29.14 % 25.00 % Dividend yield 0.24 % 0.22 % The weighted average fair value of options granted for the three months ended March 31, 2016 and 2015 were $10.45 and $6.76, respectively. A summary of the activity in the stock option plans for the three months ended March 31, 2016 follows: Shares Weighted Weighted Aggregate Outstanding at beginning of year 1,312,791 $ 13.04 6.23 $ 24,070 Granted 29,500 29.83 Exercised (14,389 ) 10.87 Forfeited, expired, or cancelled (1,082 ) 20.69 Outstanding at period end 1,326,820 $ 13.44 6.10 $ 17,998 Vested or expected to vest 1,260,479 $ 13.44 6.10 $ 17,098 Exercisable at period end 773,236 $ 10.73 4.61 $ 12,583 For the three months 2016 2015 Stock options exercised: Intrinsic value of options exercised $ 242 $ 609 Cash received from options exercised 118 780 Tax benefit realized from option exercises — 147 As of March 31, 2016, there was $1,871 of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 1.6 years. Restricted Share Award Plan A summary of activity for non-vested restricted share awards for the three months ended March 31, 2016 is as follows: Non-vested Shares Shares Weighted-Average Non-vested at December 31, 2015 105,864 $ 15.89 Granted 4,000 31.38 Vested — — Forfeited (1,622 ) 15.58 Non-vested at March 31, 2016 108,242 $ 16.46 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 March 31, 2016, there was $1,398 of total unrecognized compensation cost related to non-vested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 2.3 years. There were no shares that vested during the three months ended March 31, 2016 or 2015.

Regulatory Capital Matters

Regulatory Capital Matters	3 Months Ended
	Mar. 31, 2016
Banking and Thrift [Abstract]
Regulatory Capital Matters	NOTE 7—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. The Basel III rules additionally provide for countercyclical capital requirements so that the required amount of capital increases in times of economic expansion and decreases in times of economic contraction, consistent with safety and soundness. Under the Basel III rules, banks must maintain a capital conservation buffer consisting of additional Common Equity Tier 1 Capital equal to 2.5% of risk-weighted assets above each of the required minimum capital levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying certain discretionary bonuses. This new capital conversation buffer requirement was phased in beginning January 2016 at 0.625% of risk-weighted assets and will increase each year until fully implemented at 2.5% in January 2019. Prompt corrective action 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 March 31, 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. Management believes, as of March 31, 2016, that the Company and Bank met all capital adequacy requirements to which they are subject. 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 March 31, 2016 and December 31, 2015 for the Company and Bank: Actual Required To Be Well Amount Ratio Amount Ratio Amount Ratio March 31, 2016 Company common equity Tier 1 capital to risk-weighted assets $ 171,136 9.60 % $ 80,231 4.50 % N/A N/A Company Total Capital to risk weighted assets $ 222,655 12.49 % $ 142,633 8.00 % N/A N/A Company Tier 1 (Core) Capital to risk weighted assets $ 171,136 9.60 % $ 106,975 6.00 % N/A N/A Company Tier 1 (Core) Capital to average assets $ 171,136 7.69 % $ 89,059 4.00 % N/A N/A Bank common equity Tier 1 capital to risk-weighted assets $ 208,413 11.69 % $ 80,232 4.50 % $ 115,891 6.50 % Bank Total Capital to risk weighted assets $ 221,089 12.40 % $ 142,635 8.00 % $ 178,293 10.00 % Bank Tier 1 (Core) Capital to risk weighted assets $ 208,413 11.69 % $ 106,976 6.00 % $ 142,635 8.00 % Bank Tier 1 (Core) Capital to average assets $ 208,413 9.37 % $ 89,001 4.00 % $ 111,252 5.00 % December 31, 2015 Company common equity Tier 1 capital to risk-weighted assets $ 167,562 10.08 % $ 74,768 4.50 % N/A N/A Company Total Capital to risk weighted assets $ 186,243 11.21 % $ 132,922 8.00 % N/A N/A Company Tier 1 (Core) Capital to risk weighted assets $ 174,656 10.51 % $ 99,691 6.00 % N/A N/A Company Tier 1 (Core) Capital to average assets $ 174,656 8.48 % $ 82,362 4.00 % N/A N/A Bank common equity Tier 1 capital to risk-weighted assets $ 172,205 10.36 % $ 74,772 4.50 % $ 108,004 6.50 % Bank Total Capital to risk weighted assets $ 183,792 11.06 % $ 132,928 8.00 % $ 166,160 10.00 % Bank Tier 1 (Core) Capital to risk weighted assets $ 172,205 10.36 % $ 99,696 6.00 % $ 132,928 8.00 % Bank Tier 1 (Core) Capital to average assets $ 172,205 8.36 % $ 82,357 4.00 % $ 102,649 5.00 % Dividend Restrictions

Fair Value Disclosures [Abstract]
Fair Value	NOTE 8—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. Securities Derivatives Impaired Loans Foreclosed Assets 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 review 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.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 9—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: Three Months Ended March 31, 2016 2015 Basic Net income available to common shareholders $ 6,210 $ 3,107 Less: earnings allocated to participating securities (64 ) (40 ) Net income allocated to common shareholders $ 6,146 $ 3,067 Weighted average common shares outstanding including participating securities 10,580,304 7,970,250 Less: Participating securities (109,064 ) (102,187 ) Average shares 10,471,240 7,868,063 Basic earnings per common share $ 0.59 $ 0.39 Three Months Ended March 31, 2016 2015 Diluted Net income allocated to common shareholders $ 6,146 $ 3,067 Weighted average common shares outstanding for basic earnings per common share 10,471,240 7,868,063 Add: Dilutive effects of assumed exercises of stock options 559,017 432,808 Add: Dilutive effects of assumed exercises of stock warrants 12,426 12,951 Average shares and dilutive potential common shares 11,042,683 8,313,822 Dilutive earnings per common share $ 0.56 $ 0.37 Stock options for 62,167 and 3,000 shares of common stock were not considered in computing diluted earnings per common share for the three months ended March 31, 2016 and 2015 because they were antidilutive.

Subordinated Debt Issuance	NOTE 11—SUBORDINATED DEBT ISSUANCE On March 31, 2016, the Company issued $40,000 in aggregate principal amount of fixed-to-floating rate Subordinated Notes due 2026 (the “Notes”) in a public offering to accredited institutional investors. The Notes will mature on March 30, 2026 unless redeemed prior to that date. The Company may redeem the Notes in whole or in part on or after March 30, 2021, and in whole, but not in part, at any time within 90 days following a “Regulatory Capital Treatment Event”, as defined in the First Supplemental Indenture, dated as of March 31, 2016, between the Company and U.S. Bank National Association, as trustee (the “Supplemental Indenture”) governing the Notes. The redemption price for any redemption will be 100% of the principal amount of the Notes, plus unpaid interest, if any, accrued to but excluding the date of redemption. Any early redemption of the Notes will be subject to the receipt of the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to the extent then required under applicable laws or regulations, including capital regulations. There is no sinking fund for the Notes. The Notes initially bear interest at 6.875% per year, payable semi-annually in arrears on March 30 and September 30 of each year, beginning on September 30, 2016, and going through March 29, 2021. Thereafter, the notes will bear interest at an annual floating rate equal to three-month LIBOR as determined for the applicable quarterly period, plus a spread of 5.636%, with interest payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year, beginning on June 30, 2021. The Notes are unsecured and will rank at least equally with all of the Company’s other unsecured subordinated indebtedness and will be effectively subordinated to all of our secured debt to the extent of the value of the collateral securing such debt. The Notes will be subordinated in right of payment to all of our existing and future senior indebtedness, and will rank structurally junior to all existing and future liabilities of our subsidiaries including, in the case of Franklin Synergy Bank (the “Bank”), its depositors, and any preferred equity holders of our subsidiaries. The holders of the Notes may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation, or similar proceeding. The sale of the Notes yielded net proceeds of approximately $38,843 after deducting the placement agents’ fees and estimated expenses payable by the Company. The Company used the net proceeds from the offering to pay off a $10 million borrowing that had been used to redeem the shares of Senior Non-Cumulative Perpetual Preferred Stock, Series A (the “Series A Preferred Stock”) issued to the United States Department of the Treasury (“Treasury”) in connection with the Company’s participation in the Small Business Lending Fund and to fund future growth of the Bank. The estimated issuance costs related to the Notes amounted to $1,157 and will be amortized as interest expense over the ten-year term of the Notes. For regulatory capital purposes, the Notes are treated as Tier 2 capital and are included in total regulatory capital when calculating the Company’s total capital to risk weighted assets ratio as indicated in Note 7 of these consolidated financial statements.
