Unrealized losses on debt securities have not been recognized into income because the issuers bonds are of high credit quality (rated AA or higher), management does not intend to sell and it is likely 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 recover as the bonds approach maturity.

	The adequacy of the allowance for loan losses is assessed at the end of each calendar quarter. The level of the allowance is based upon evaluation of the loan portfolio, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, historical loss experience, industry and peer bank loan quality indications and other pertinent factors.
	The following table presents the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method as of March 31, 2014 and December 31, 2013. For purposes of this disclosure, recorded investment in loans excludes accrued interest receivable and loan fees, net due to immateriality.

Credit Quality Indicators: The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. 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.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows as of March 31, 2014 and December 31, 2013:

	NOTE 5 — SHARE-BASED PAYMENTS
	In connection with the offering in 2007, the Company’s original shareholders received as part of their initial investment 131,250 warrants, one 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 November 26, 2007 and were exercisable in whole or in part up to five years following the date of issuance. All warrants issued in connection with the 2007 offering have expired. In connection with the most recent offering which was completed during 2010, 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 3,000 warrants exercised during the three months ended March 31, 2013, for which the Company received cash proceeds of $30. The exercised warrants had an intrinsic value of $3 at the date of exercise. No warrants have been exercised during 2014. At March 31, 2014, there were 31,877 outstanding warrants associated with the 2010 offering.
	In the event the Common Stock of the Company is to be registered under the Securities Act of 1933, as amended (the “Securities Act”), or is 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 thereafter with not less than thirty (30) days’ written notice to the holder of such 2010 Warrant, 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.
	Stock Option Plan: The Company’s 2007 Stock Option Plan (stock option plan or the Plan), which was shareholder-approved, permitted the grant of share options to its employees, organizers and directors for up to 551,250 shares of common stock. In April, 2013, the Plan was amended to offer additional forms of equity compensation, to change the Plan’s name to the Franklin Financial Network, Inc. 2007 Omnibus
	Equity Incentive Plan, and to increase the number of authorized shares to 1,500,000. The Company believes that such awards better align the interests of its employees with those of its shareholders. 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 3 to 5 years and have a 10-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.
	During 2007, the Company granted 33,750 options to its organizers under the Plan. These options were granted in accordance with each organizer’s financial contribution to the Company during its organization period, and vested over a five year period. No service element was included in the criteria used for determining grant awards. Accordingly, these options are not being expensed as stock-based compensation.
	During 2013, the Company granted employees the option to acquire common shares of the Company, plus a cash award, in exchange for existing vested options held by the employee. Options that were exchanged were surrendered and considered cancelled. As part of this exchange, a total of 166,448 options were cancelled in exchange for 32,814 shares of common stock and cash awards totaling $142.
	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,
		2014			2013
	Risk-free interest rate		2.48	%		1.37	%
	Expected term		7.5 years			7.5 years
	Expected stock price volatility		11.04	%		12.63	%
	Dividend yield		0.43	%		1.09	%
	The weighted average fair value of options granted for the three months ended March 31, 2014 and 2013 were $2.58 and $1.75, respectively.
	A summary of the activity in the stock option plans for the three months ended March 31, 2014 follows:
		Shares			Weighted			Weighted		Aggregate
					Average			Average		Intrinsic
					Exercise			Remaining		Value
					Price			Contractual
								Term
	Outstanding at beginning of year		946,644		$	11.27			6.81	$	1,635

	Exercisable at period end		553,644		$	10.88			5.61	$	1,450
	As of March 31, 2014 there was $456 of total unrecognized compensation cost related to nonvested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 1.8 years.
	Restricted Share Award Plan: Additionally, the Company’s 2007 Omnibus Equity Incentive Plan provides for the granting of restricted share awards and other performance related incentives. During 2013, the Company awarded 30,105 of restricted common shares to employees of the Company. When the 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. These awards have a vesting period of 5 years and vest in equal annual installments on the anniversary date of the grant.
	A summary of activity for nonvested restricted share awards for the three ended March 31, 2014 is as follows:
	Nonvested Shares	Shares			Weighted-Average
					Grant-Date
					Fair Value
	Nonvested at December 31, 2013		28,685		$	13

	Forfeited		(216	)		13
	Nonvested at March 31, 2014		24,129		$	13
	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, 2014 there was $261 of total unrecognized compensation cost related to nonvested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 4.2 years.

REGULATORY CAPITAL MATTERS	'
	NOTE 6 — 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. Management believes as of March 31, 2014, the Company and Bank meet all capital adequacy requirements to which they are subject.
	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, 2014, 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 March 31, 2014 and December 31, 2013 for the Company and Bank.

	Dividend Restrictions: The Company’s principal source of funds for dividend payments is dividends received from the Bank. Banking regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years, subject to the capital requirements described above. During 2014, the Bank could, without prior approval of the applicable federal and state bank regulatory agencies, declared dividends of approximately $9,190 plus any 2014 net profits retained to the date of declaration.

Fair Value Disclosures [Abstract]	'
FAIR VALUE	'
	NOTE 7 — 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.
	The Company used the following methods and significant assumptions to estimate the fair value of each type of asset and liability:
	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). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3).
	Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2).
	Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. 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. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
	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.
	Loans Held For Sale: Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments, from third party investors (Level 2).
	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:

Impaired loans with specific allocations, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $2,667, with a valuation allowance of $614 at March 31, 2014, resulting in $66 additional provision for loan losses for the three month period ending March 31, 2014. At December 31, 2013 impaired loans had a carrying amount of $2,601, with a valuation allowance of $548. For the three months ended March 31, 2013, no additional provision for loan losses was recorded related to impaired loans recorded at fair value of collateral.
There were no foreclosed assets as of March 31, 2014. Foreclosed assets measured at fair value less costs to sell, had a net carrying amount of $181 for the year ended December 31, 2013. There were no properties included in this amount that had required write-downs to fair value. Foreclosed assets measured at fair value less costs to sell were written down to fair value resulting in a write-down of $190 for the three month period ending March 31, 2013.

The methods and assumptions not previously described used to estimate fair value 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: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price.
The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.
(c) Restricted Equity Securities: It is not practical to determine the fair value of FHLB or Federal Reserve Bank stock due to restrictions placed on its transferability.
(d) 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 2 classification.
(e) 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.
(f) 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.
(g) 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.
(h) Accrued Interest Receivable/Payable: The carrying amounts of accrued interest approximate fair value resulting in a Level 1 or Level 2 classification based on the asset/liability that they are associated with.
(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.

EARNINGS PER SHARE	'
	NOTE 8 — 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:
