Basis of Presentation	BASIS OF PRESENTATION
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair statement of financial condition and the results of operations have been included. All such adjustments were of a normal recurring nature. Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net loss or shareholders’ equity.
	The consolidated financial statements include the accounts of First Security Group, Inc. ("First Security" , "FSG" or the "Company") and FSGBank, N.A. ("FSGBank" or the "Bank"), its wholly owned subsidiary bank. All significant intercompany balances and transactions have been eliminated.
	Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or any other period. These interim financial statements should be read in conjunction with the Company’s latest annual consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	Recent Developments
	On March 25, 2015, First Security Group, Inc. and Atlantic Capital Bancshares, Inc. ("Atlantic Capital") jointly announced the signing of a definitive merger agreement pursuant to which Atlantic Capital will acquire First Security (the "Merger"). The transaction has been unanimously approved by the board of directors of each company. On March 27, 2015, First Security filed a Current Report on Form 8-K that provides additional details relating to the merger agreement. A copy of the agreement is filed as Exhibit 2.1 to such Form 8-K.
	Under terms of the agreement, Atlantic Capital will purchase First Security for total consideration of approximately $160 million. FSG shareholders may elect cash equal to $2.35 per share, stock based on a fixed exchange ratio of 0.188 shares of Atlantic Capital common stock for each FSG share or any combination thereof. Atlantic Capital intends to register its shares with the SEC and seek a listing on NASDAQ concurrent with the closing of the transaction. The transaction is expected to close in the third or fourth quarter of 2015 and is subject to Atlantic Capital and First Security shareholder approval, regulatory approval and other conditions set forth in the merger agreement.

Banking and Thrift [Abstract]
Regulatory Matters	REGULATORY CAPITAL
	Regulatory Capital Ratios
	Banks and bank holding companies, as regulated institutions, are subject to various regulatory capital requirements administered by the OCC and Federal Reserve, the primary federal regulators for FSGBank and the Company, respectively. The OCC and Federal Reserve have adopted minimum capital regulations or guidelines that categorize components and the level of risk associated with various types of assets. Financial institutions are expected to maintain a level of capital commensurate with the risk profile assigned to their assets in accordance with the guidelines. Regulatory capital guidelines require that capital be measured in relation to the credit and market risks of both on- and off-balance-sheet items as calculated under regulatory accounting practices. On January 1, 2015, the Company became subject to Basel III rules, which include transition provisions through January 1, 2019. Under Basel III, total capital consist of two tiers of capital, Tier 1 and Tier 2. Tier 1 capital is further composed of Common Equity Tier 1 Capital and additional Tier 1 capital.
	The transition provisions include important differences in determining the composition of regulatory capital between the Basel I Rules and Basel III rules including, changes in capital deductions related to the Company's deferred tax assets and defined benefit pension assets, and the inclusion of unrealized gains and losses on AFS debt and certain marketable equity securities recorded in accumulated OCI. These changes will be impacted by, among other things, future changes in interest rates, overall earnings performance and company actions. Changes to the composition of regulatory capital under Basel III, as compared to the Basel I rules, are recognized in 20 percent annual increments, and will be fully recognized as of January 1, 2019. When presented on a fully phased-in basis, capital, risk-weighted assets and the capital ratios assume all regulatory capital adjustments and deductions are fully recognized.
	Common Equity Tier 1 Capital primarily includes qualifying common shareholders' equity, retained earnings, accumulated other comprehensive income and certain minority interest. Goodwill, disallowed intangible assets and certain disallowed deferred tax assets are excluded from Common Equity Tier 1 Capital.
	Additional Tier 1 capital primarily includes qualifying non-cumulative preferred stock, trust preferred securities subject to phase-out and certain minority interests. Certain deferred tax assets are also excluded.
	Tier 2 capital primarily consists of qualifying subordinated debt, a limited portion of the allowance for loan and lease losses, trust preferred securities subject to phase-out and reserves for unfunded lending commitments. The Company's total capital is the sum of Tier 1 capital plus Tier 2 capital.
	To meet adequately capitalized regulatory requirements, an institution must maintain a Common Equity Tier 1 Capital of 4.5%, a Tier 1 capital ratio of 6.0% and a Total capital ratio of 8.0%. A “well-capitalized” institution must generally maintain capital ratios 200 bps higher than the minimum guidelines. The risk-based capital rules have been further supplemented by a Tier 1 leverage ratio, defined as Tier 1 capital divided by quarterly average total assets, after certain adjustments. The Bank must maintain a Tier 1 leverage ratio of at least 5.0% to be classified as “well capitalized.” Failure to meet the capital requirements established by the joint agencies can lead to certain mandatory and discretionary actions by regulators that could have a material adverse effect on the Company's consolidated financial statements.
	The Basel III rules also introduced a capital conservation buffer which will be phased in over four years beginning on January 1, 2016, with a maximum buffer of 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. Failure to maintain the required capital conservation buffer will result in limitations on capital distributions and on discretionary bonuses to executive officers.
	The Basel III rules were implemented and are reflected in the March 31, 2015 capital levels and ratios in the tables below. The Company opted out of the AOCI treatment under the new requirements and, as such, unrealized security gains and losses will continue to be excluded from bank regulatory capital.
	The following table presents capital ratios for the Company and FSGBank at March 31, 2015, December 31, 2014 and March 31, 2014:

	For the three months ended March 31, 2015 and 2014, no amounts were reclassified into interest income due to gains on derivatives. For the three months ended March 31, 2015 and 2014, there were $8 thousand and $371 thousand, respectively, of gains reclassified from unrealized gains (losses) on available-for-sale securities to earnings as a result of sales during the period.
	During 2013, approximately $143 million of available-for-sale securities were transferred to the held-to-maturity classification. As of the transfer date, the securities held an unrealized loss of approximately $8.9 million. The fair value as of the transfer date became the new amortized cost basis with the unrealized loss, along with any remaining purchase discount or premium, being reclassified out of accumulated other comprehensive loss over the remaining life of the security. For the three months ended March 31, 2015 and 2014, approximately $407 thousand and $482 thousand, respectively, of the unrealized loss was reclassified out of accumulated other comprehensive loss.

Earnings Per Share [Abstract]
Earnings Per Common Share	EARNINGS PER COMMON SHARE
	The difference in basic and diluted weighted average shares is due to the assumed conversion of outstanding stock options and restricted stock awards using the treasury stock method. The Company has issued certain restricted stock awards, which are unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents. These restricted shares are considered participating securities. Accordingly, the Company calculated net income available to common shareholders pursuant to the two-class method, whereby net income is allocated between common shareholders and participating securities. In periods of a net loss, no allocation is made to participating securities as they are not contractually required to fund net losses. The computation of basic and diluted earnings per share is as follows:

As of the transfer date, the securities held an unrealized loss of approximately $8.9 million. The fair value as of the transfer date became the new amortized cost basis with the unrealized loss, along with any remaining purchase discount or premium, being reclassified into accumulated other comprehensive income are amortized over the life of the security. No gain or loss was recognized at the time of the transfer. For the three months ended March 31, 2015 and 2014, approximately $407 thousand and $482 thousand, respectively, of the unrealized loss was reclassified out of accumulated other comprehensive income.

As of March 31, 2015, the Company performed an impairment assessment of the available-for-sale and held-to-maturity securities in its portfolio that had unrealized losses to determine whether the decline in the fair value of these securities below their cost was other-than-temporary. Under authoritative accounting guidance, impairment is considered other-than-temporary if any of the following conditions exists: (1) the Company intends to sell the security, (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized costs basis or (3) the Company does not expect to recover the security’s entire amortized cost basis, even if the Company does not intend to sell. Additionally, accounting guidance requires that for impaired available-for-sale securities that the Company does not intend to sell and/or that it is not more-likely-than-not that the Company will have to sell prior to recovery but for which credit losses exist, the other-than-temporary impairment should be separated between the total impairment related to credit losses, which should be recognized in current earnings, and the amount of impairment related to all other factors, which should be recognized in other comprehensive income. Losses related to held-to-maturity securities are not recorded, as these securities are carried at their amortized cost. If a decline is determined to be other-than-temporary due to credit losses, the cost basis of the individual available-for-sale or held-to-maturity security is written down to fair value, which then becomes the new cost basis. The new cost basis would not be adjusted in future periods for subsequent recoveries in fair value, if any.
In evaluating the recovery of the entire amortized cost basis, the Company considers factors such as (1) the length of time and the extent to which the market value has been less than cost, (2) the financial condition and near-term prospects of the issuer, including events specific to the issuer or industry, (3) defaults or deferrals of scheduled interest, principal or dividend payments and (4) external credit ratings and recent downgrades.
As of March 31, 2015, gross unrealized losses in the Company’s available-for-sale portfolio totaled $238 thousand, compared to $367 thousand as of December 31, 2014 and $1.5 million as of March 31, 2014. As of March 31, 2015, gross unrecognized losses in the Company's held-to-maturity portfolio totaled $68 thousand compared to $305 thousand as of December 31, 2014 and $710 thousand as of March 31, 2014. As of March 31, 2015, the available-for-sale securities unrealized losses in mortgage-backed securities (consisting of fourteen securities), municipals (consisting of one security) and the held-to-maturity unrecognized losses in mortgage-backed securities (consisting of eleven securities), municipals (consisting of seventeen securities) and federal agencies (consisting of twenty-two securities) are primarily due to widening credit spreads and changes in interest rates subsequent to purchase. Between March 31, 2014 and March 31, 2015, the rate on the 10-year U.S. Treasury decreased from approximately 2.73% to 1.94%. As this represented a decrease in interest rates, the market valuation of the Company's securities adjusted accordingly. The unrealized loss in other available-for-sale securities relates to one corporate note. The unrealized loss in the corporate note is primarily due to changes in interest rates subsequent to purchase. The Company does not intend to sell the available-for-sale investments with unrealized losses and it is not more likely than not that the Company will be required to sell the available-for-sale investments before recovery of their amortized cost basis, which may be maturity. Based on results of the Company’s impairment assessment, the unrealized losses related to the available-for-sale securities and the unrecognized losses related to the held-to-maturity securities at March 31, 2015 are considered temporary.
On December 10, 2013, the Federal Reserve and other regulators jointly issued a proposed rule implementing requirements of a new Section 13 to the Bank Holding Company Act, commonly referred to as the “Volcker Rule.” We continue to monitor and review applicable regulatory guidance on the implementation of the Volcker Rule. The Federal Reserve Board granted an extension for conformance until July 21, 2017 and announced that it intends to exercise its authority to give banking entities two additional one-year extensions to conform their ownership interests in and sponsorship of certain collateralized loan obligations (“CLOs”) covered by the Volcker Rule.
As of March 31, 2015, the Company has identified approximately $11.2 million of collateralized loan obligations ("CLOs") within its investment security portfolio that may be impacted by the Volcker Rule. If these securities are deemed to be prohibited bank investments, the Company would have to sell the securities prior to the compliance date of July 21, 2017. At this time, the Company continues to evaluate the additional regulatory guidance on the subject as well as the specific terms of the CLOs in the Company's portfolio to determine whether such CLOs will remain permitted investments. The unrealized gain as of March 31, 2015 for the Company's CLOs totaled $51 thousand.

Loans Held for Sale	LOANS HELD-FOR-SALE
	The Company maintains loans held-for-sale in connection with three distinct departments: the mortgage department, the government lending department and the TriNet division. The Company's mortgage department primarily originates long-term loans held-for-sale and uses various correspondent relationships to sell the loans on the secondary market. The mortgage department also originates certain mortgage loans to be retained and classifies as loans held-for-investment. From time to time, certain of these loans may be marketed and sold in order to manage the Company's interest rate risk position and concentration limits. The government lending department originates SBA and USDA government guaranteed loans with the primary purpose of selling the guaranteed portion in the secondary market. The Company's TriNet division originates construction loans for pre-leased "build to suit" projects and provides interim and long-term financing to professional developers and private investors of commercial real estate with or subject to long-term leases to tenants that are investment grade or have investment grade attributes. The Company classifies all TriNet originations as held-for-investment. From time to time, the Company may evaluate a portion of the originated loans to sell in order to manage the Company's overall interest rate risk and asset-liability sensitivity. The Company transfers the loans to held-for-sale once specific loans are identified and the decision to sell the loan has been made. This is generally represented by the Company's execution of a letter of intent.
	Residential loans held-for-sale by the Company's mortgage department totaled $1.5 million, $2.3 million and $1.9 million at March 31, 2015, December 31, 2014 and March 31, 2014, respectively.
	The Company's government lending department had loans held-for-sale at March 31, 2015 of approximately $1.1 million. This amount represents the portion of the SBA loan the Company intends to sell to third parties. Sales of SBA loans have generated income of approximately $14 thousand and $22 thousand for the three months ended March 31, 2015 and 2014, respectively.
	During the first quarter of 2015, the Company identified a group of commercial real estate loans to be sold to third parties from the TriNet division. These loans were transferred from loans held-for-investment to the loans held-for-sale at the lower of cost or market value of $18.6 million, which was net of an allowance of $26 thousand. During the first quarter of 2015, the Company also identified a group of residential 1-4 family loans to be sold to a third party. These loans were transferred from loans held-for-investment to loans held-for-sale at a market value of $2.1 million, which was net of an allowance of $20 thousand. The sale of these loans is expected to take place in the second quarter of 2015. During the first quarter of 2014, the Company identified a group of commercial real estate loans to be sold to third parties from the TriNet division. These loans were transferred to loans held-for-sale at the lower of cost or market value at a value of $33.6 million, which was net of an allowance of approximately $100 thousand. During the third quarter of 2014, the Company identified additional commercial real estate loans from the TriNet division to sell. These loans were transferred to loans held-for-sale at the lower of cost or market value at a value of $45.6 million, which was net of an allowance of approximately $148 thousand. A portion of the loans transferred during 2014 were sold in the first quarter of 2015 resulting in a gain of approximately $1.0 million for the three months ended March 31, 2015.

	The allowance for loan and lease losses is composed of two primary components: (1) specific impairments for substandard/nonaccrual loans and leases and (2) general allocations for classified loan pools, including special mention and substandard/accrual loans, as well as all remaining pools of loans. The Company accumulates pools based on the underlying classification of the collateral. Each pool is assigned a loss severity rate based on historical loss experience and various qualitative and environmental factors, including, but not limited to, credit quality and economic conditions. The Company may include an unallocated component to the allowance for inherent risks within the loan portfolio that cannot be quantified through the loss factors or the qualitative factors. The Company determines the allowance on a quarterly basis. Because of uncertainties inherent in the estimation process, management’s estimate of credit losses in the loan portfolio and the related allowance may materially change in the near term. However, the amount of the change that is reasonably possible cannot be estimated.
	Included in the Company's loan portfolio are government guaranteed loans the Company purchased totaling $49.0 million, $51.3 million and $50.6 million at March 31, 2015, December 31, 2014 and March 31, 2014, respectively. Due to the nature of these loans, there is no specific or general allocation calculated or included in the allowance for loan and lease losses for this group of loans. These loans are reported within the appropriate classification, primarily commercial loans or commercial real estate loans.
	The following table presents an analysis of the activity in the allowance for loan and lease losses for the three months ended March 31, 2015 and 2014. The provision for loan and lease losses in the tables below do not include the Company’s provision accrual for unfunded commitments of $2 thousand and $6 thousand for the three months ended March 31, 2015 and 2014, respectively. The reserve for unfunded commitments is included in other liabilities in the consolidated balance sheets and totaled $308 thousand, $306 thousand and $288 thousand at March 31, 2015, December 31, 2014 and March 31, 2014, respectively.

The Company utilizes a risk rating system to evaluate the credit risk of its loan portfolio. The Company classifies loans as: pass, special mention, substandard/non-impaired, substandard/impaired, doubtful or loss. The following describes the Company's classifications and the various risk indicators associated with each rating.
A pass rating is assigned to those loans that are performing as contractually agreed and do not exhibit the characteristics of the criticized and classified risk ratings as defined below. The Company utilizes six grade classifications within the Pass rating based on the varying risk characteristics of the loan. Pass loan pools do not include the unfunded portions of binding commitments to lend, standby letters of credit, deposit secured loans or mortgage loans originated with commitments to sell in the secondary market. Loans that are not required to have an allowance reserve include: loans secured by segregated deposits held by FSGBank, loans held-for-sale, and the government guaranteed portion of SBA and USDA loans.
A special mention loan risk rating is considered criticized but is not considered as severe as a classified loan risk rating. Special mention loans contain one or more potential weakness(es), which if not corrected, could result in an unacceptable increase in credit risk at some future date. These loans may be characterized by the following risks and/or trends:
Loans to Businesses:
•	Downward trend in sales, profit levels and margins
•	Impaired working capital position compared to industry
•	Cash flow strained in order to meet debt repayment schedule
•	Technical defaults due to noncompliance with financial covenants
•	Recurring trade payable slowness
•	High leverage compared to industry average with shrinking equity cushion
•	Questionable abilities of management
•	Weak industry conditions
•	Inadequate or outdated financial statements
Loans to Businesses or Individuals:
•	Loan delinquencies and overdrafts may occur
•	Original source of repayment questionable
•	Documentation deficiencies may not be easily correctable
•	Loan may need to be restructured
•	Collateral or guarantor offers adequate protection
•	Unsecured debt to tangible net worth is excessive
A substandard loan risk rating is characterized as having specifically identified weaknesses and deficiencies typically resulting from severe adverse trends of a financial, economic, or managerial nature, and may warrant non-accrual status.
The Company segregates substandard loans into two classifications based on the Company’s allowance methodology for impaired loans. The Company defines a substandard/impaired loan as a substandard loan relationship in excess of $250 thousand that is individually reviewed. Substandard loans have a greater likelihood of loss and may require a protracted work-out plan. In addition to the factors listed for special mention loans, substandard loans may be characterized by the following risks and/or trends:
Loans to Businesses:
•	Sustained losses that have severely eroded equity and cash flows
•	Concentration in illiquid assets
•	Serious management problems or internal fraud
•	Chronic trade payable slowness; may be placed on COD or collection by trade creditor
•	Inability to access other funding sources
•	Financial statements with adverse opinion or disclaimer; may be received late
•	Insufficient documented cash flows to meet contractual debt service requirements
Loans to Businesses or Individuals:
•	Chronic or severe delinquency or has met the retail classification standards which is generally past dues greater than 90 days
•	Frequent overdrafts
•	Likelihood of bankruptcy exists
•	Serious documentation deficiencies
•	Reliance on secondary sources of repayment which are presently considered adequate
•	Demand letter sent
•	Litigation may have been filed against the borrower
Loans with a risk rating of doubtful are individually analyzed to determine the Company's best estimate of the loss based on the most recent assessment of all available sources of repayment. Doubtful loans are considered impaired and placed on nonaccrual. For doubtful loans, the collection or liquidation in full of principal and/or interest is highly questionable or improbable. The Company estimates the specific potential loss based upon an individual analysis of the relationship risks, the borrower’s cash flow, the borrower’s management and any underlying secondary sources of repayment. The amount of the estimated loss, if any, is then either specifically reserved in a separate component of the allowance or charged-off. In addition to the characteristics listed for substandard loans, the following characteristics apply to doubtful loans:
Loans to Businesses:
•	Normal operations are severely diminished or have ceased
•	Seriously impaired cash flow
•	Numerous exceptions to loan agreement
•	Outside accountant questions entity’s survivability as a “going concern”
•	Financial statements may be received late, if at all
•	Material legal judgments filed
•	Collection of principal and interest is impaired
•	Collateral/Guarantor may offer inadequate protection
Loans to Businesses or Individuals:
•	Original repayment terms materially altered
•	Secondary source of repayment is inadequate
•	Asset liquidation may be in process with all efforts directed at debt retirement
•	Documentation deficiencies not correctable
The consistent application of the above loan risk rating methodology ensures that the Company has the ability to track historical losses and appropriately estimate potential future losses in our allowance. Additionally, appropriate loan risk ratings assist the Company in allocating credit and special asset personnel in the most effective manner. Significant changes in loan risk ratings can have a material impact on the allowance and thus a material impact on the Company's financial results by requiring significant increases or decreases in provision expense. The Company individually reviews these relationships on a quarterly basis to determine the required allowance or loss, as applicable.
During the first quarter of 2015, the Company changed the dollar threshold utilized to evaluate loan relationships for impairment. Prior to 2015, the dollar threshold utilized was $500 thousand. The Company determined it was appropriate given alignment with a change in internal procedures and controls related to credit quality monitoring and loan review scope. The reduction in the dollar threshold impacts the Company's estimated allowance for loan and lease loss. The change in our estimated allowance for loan and lease losses and provision expense, due to the change in accounting policy, was recorded in the period the change in the dollar threshold took place. The reduction in the dollar threshold increased impaired loans by approximately $1.0 million at March 31, 2015. The change in the dollar threshold also decreased the estimated allowance for loan and lease loss and associated provision expense by approximately $92 thousand for the three months ended March 31, 2015.

Other Borrowings	OTHER BORROWINGS
	Other borrowings at March 31, 2015, December 31, 2014 and March 31, 2014 consist of short-term variable or fixed rate advances from the Federal Home Loan Bank of Cincinnati ("FHLB") totaling $24.5 million, $56.0 million and $37.6 million, respectively. There were no other borrowings at March 31, 2015, December 31, 2014 or March 31, 2014.
	Pursuant to the blanket agreement for advances and security agreements with the FHLB, advances as of March 31, 2015, December 31, 2014 and March 31, 2014 were secured by the Company’s unencumbered qualifying 1-4 family first mortgage loans subject to varying limitations determined by the FHLB, investment securities and by the FHLB stock owned by the Company. As of March 31, 2015, December 31, 2014 and March 31, 2014, the Company had loans totaling $71.7 million, $65.3 million and $147.7 million, respectively, and investment securities totaling $89.6 million, $96.0 million and $103.7 million, respectively, pledged as collateral at the FHLB.
	As a member of FHLB, the Company must own FHLB stock. The amount of FHLB stock required to be held is subject the Company’s asset size and outstanding FHLB advances. At March 31, 2015, December 31, 2014 and March 31, 2014, the Company owned FHLB stock totaling $3.3 million, $3.3 million and $2.5 million, respectively. The FHLB stock is recorded in other assets on the Company’s consolidated balance sheet. Based on the collateral and the Company's holdings of FHLB stock, the Company is eligible to borrow up to a total of $160.3 million at March 31, 2015.
	The terms of the FHLB advances as of March 31, 2015, December 31, 2014 and March 31, 2014 are as follows:

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	The Company accounts for income taxes in accordance with ASC 740, which requires an asset and liability approach for the financial accounting and reporting of income taxes. Under this method, deferred income taxes are recognized for the expected future tax consequences of differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. These balances are measured using the enacted tax rates expected to apply in the year(s) in which these temporary differences are expected to reverse. The effect on deferred income taxes of a change in tax rates is recognized in income in the period when the change is enacted.
	In accordance with ASC 740, the Company is required to establish a valuation allowance for deferred tax assets when it is “more likely than not” that a portion or all of the deferred tax assets will not be realized. The evaluation requires significant judgment and extensive analysis of all available positive and negative evidence, the forecasts of future income, applicable tax planning strategies and assessments of the current and future economic and business conditions.
	During 2010, the Company established a deferred tax asset valuation allowance after evaluating all available positive and negative evidence. A valuation allowance is required when it is "more likely than not" that the deferred tax assets will not be realized. The evaluation requires significant judgment and extensive analysis of all available positive and negative evidence, the forecasts of future income, applicable tax planning strategies and assessments of the current and future economic and business conditions. For the three months ended March 31, 2015, the Company reported net income, which is positive evidence. Currently, the Company has determined that there is not sufficient positive evidence to reach a "more likely than not" conclusion that the deferred tax assets will be realized and as such, a full valuation allowance exists as of March 31, 2015. The Company evaluates the valuation allowance on a quarterly basis. As of March 31, 2015, the valuation allowance totals $61.1 million resulting in a net deferred tax asset of zero.
	For the three months ended March 31, 2015 and 2014, the Company recognized an income tax provision of $145 thousand and $132 thousand, respectively.
	The Company evaluated its material tax positions as of March 31, 2015. Under the “more-likely-than-not” threshold guidelines, the Company believes it has identified all significant uncertain tax benefits. The Company evaluates, on a quarterly basis or sooner if necessary, to determine if new or pre-existing uncertain tax positions are significant. In the event a significant uncertain tax position is determined to exist, penalty and interest will be accrued, in accordance with Internal Revenue Service guidelines, and recorded as a component of income tax expense in the Company’s consolidated financial statements.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION
	As of March 31, 2015, the Company has three share-based compensation plans, the 2012 Long-Term Incentive Plan (the "2012 LTIP"), the 2002 Long-Term Incentive Plan (the "2002 LTIP") and the 1999 Long-Term Incentive Plan (the "1999 LTIP" and, together with the 2012 LTIP and 2002 LTIP, the "Plans"). The Plans are administered by the Compensation Committee of the Board of Directors (the "Committee"), which selects persons eligible to receive awards and determines the number of shares and/or options subject to each award, the terms, conditions and other provisions of the award. The Plans are described in further detail below.
	During the Company's participation in TARP CPP, the terms of awards were also subject to compliance with applicable TARP compensation regulations prior to the exchange of the TARP Preferred Stock on April 11, 2013.
	The 2012 LTIP was approved by the shareholders of the Company at the Company's 2012 annual meeting as previously reported on a Current Report on Form 8-K filed June 26, 2012 and subsequently amended at the Company's 2013 annual meeting as reported on a Current Report on Form 8-K filed on July 26, 2013. The amendment increased the shares reserved for issuance from 175,000 shares to 6,250,000 shares and was effective on July 24, 2013. The 2012 Long-Term Incentive Plan permits the Committee to make a variety of awards, including incentive and nonqualified options to purchase shares of First Security's common stock, stock appreciation rights, other share-based awards which are settled in either cash or shares of First Security's common stock and are determined by reference to shares of stock, such as grants of restricted common stock, grants of rights to receive stock in the future, or dividend equivalent rights, and cash performance awards, which are settled in cash and are not determined by reference to shares of First Security's common stock ("Awards"). These discretionary Awards may be made on an individual basis or through a program approved by the Committee for the benefit of a group of eligible persons. As of March 31, 2015, the number of shares available under the 2012 LTIP for future grants was 2,696,500.
	The 2002 LTIP was approved by the shareholders of the Company at the Company's 2002 annual meeting and subsequently amended by the shareholders of the Company at the Company's 2004 and 2007 annual meetings to increase the number of shares available for issuance under the 2002 LTIP by 480 thousand and 750 thousand shares, respectively. The total number of shares authorized for awards prior to the 10-for-1 reverse stock split was 1.5 million. As a result of the 10-for-1 reverse stock split in 2012, the total shares currently authorized under the 2002 LTIP is 151,800, of which not more than 20% may be granted as awards of restricted stock. Eligible participants include eligible employees, officers, consultants and directors of the Company or any affiliate. The exercise price per share of a stock option granted may not be less than the fair market value as of the grant date. The exercise price must be at least 110% of the fair market value at the grant date for options granted to individuals, who at the grant date, are 10% owners of the Company’s voting stock (each a 10% owner). Restricted stock may be awarded to participants with terms and conditions determined by the Committee. The term of each award is determined by the Committee, provided that the term of any incentive stock option may not exceed ten years (five years for 10% owners) from its grant date. Each option award vests in approximately equal percentages each year over a period of not less than three years from the date of grant as determined by the Committee subject to accelerated vesting under terms of the 2002 LTIP or as provided in any award agreement. As of March 31, 2015, there are no shares available for future grants under the 2002 LTIP.
	Participation in the 1999 LTIP is limited to eligible employees. The total number of shares of stock authorized for awards prior to the 10-for-1 reverse stock split was 936 thousand. As a result of the 10-for-1 reverse stock split in 2013, the total shares currently authorized under the 1999 LTIP is 93,600, of which not more than 10% could be granted as awards of restricted stock. Under the terms of the 1999 LTIP, incentive stock options to purchase shares of the Company’s common stock may not be granted at a price less than the fair market value of the stock as of the date of the grant. Options must be exercised within ten years from the date of grant subject to conditions specified by the 1999 LTIP. Restricted stock could also be awarded by the Committee in accordance with the 1999 LTIP. Generally, each award vests in approximately equal percentages each year over a period of not less than three years and vest from the date of grant as determined by the Committee subject to accelerated vesting under terms of the 1999 LTIP or as provided in any award agreement. As of March 31, 2015, there are no shares available for future grants under the 1999 LTIP.

	1 Due to the deferred tax valuation allowance, tax benefit is reversed through the valuation allowance.
	During the three months ended March 31, 2015 and 2014, no options were exercised.
	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 following assumptions: expected dividend yield, expected volatility, risk-free interest rate, expected life of the option and the grant date fair value. Expected volatilities were based on historical volatilities of the Company's common stock. During 2015 and 2014, the Company utilized a regional bank index to determine expected volatilities. The Company uses historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted is based on historical data and 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.
	There were no options granted during the three months ended March 31, 2015. Options granted during the three months ended March 31, 2014 totaled 161 thousand. The fair value of options granted during the three months ended March 31, 2014 was determined using the following weighted-average assumptions as of the grant date.
			As of March 31, 2014
	Risk-free interest rate		2.13	%
	Expected term, in years		7.1
	Expected stock price volatility		40.9	%

	On February 27, 2014, as reported on a Current Report on Form 8-K filed on March 4, 2014, certain awards previously granted under the 2012 LTIP were modified effective February 28, 2014. The modification changed the vesting period from three years to five years. In addition, 96,250 supplemental stock options were authorized and will vest over a five year period in accordance with the modification. The supplemental stock options are exercisable at $2.33 per share and are otherwise identical to the original stock options and are subject to other terms and conditions of the 2012 LTIP and to the specific stock option awards.
	As of March 31, 2015, shares available for future grants to employees and directors under existing Plans were zero, zero and 2,696,500 for the 1999 LTIP, 2002 LTIP and 2012 LTIP, respectively.
	As of March 31, 2015, there was $1.7 million of total unrecognized compensation cost related to nonvested stock options granted under the Plans. The cost is expected to be recognized over a weighted-average period of 3.1 years.
	Restricted Stock
	The Plans described above allow for the issuance of restricted stock awards that may not be sold or otherwise transferred until certain restrictions have lapsed. The unearned share-based compensation related to these awards is being amortized to compensation expense over the period the restrictions lapse. The share-based expense for these awards was determined based on the market price of the Company’s stock at the grant date applied to the total number of shares that were anticipated to fully vest and then amortized over the vesting period.
	As of March 31, 2015, unearned share-based compensation associated with these awards totaled $1.5 million. The Company recognized compensation expense, net of forfeitures, of $138 thousand and $148 thousand for the three months ended March 31, 2015 and 2014, respectively, related to the amortization of deferred compensation that was included in salaries and benefits in the accompanying consolidated statements of operations. The remaining cost is expected to be recognized over a weighted-average period of 3.2 years.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS
	The authoritative accounting guidance for fair value measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.
	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 can 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 company's own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2015, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
	The Company used the following methods and significant assumptions to estimate fair value:
	Cash and cash equivalents: The carrying value of cash and cash equivalents approximates fair value.
	Interest bearing deposits in banks: The carrying amounts of interest bearing deposits in banks approximate fair value.
	Federal Home Loan Bank Stock and Federal Reserve Bank Stock: It is not practical to determine the fair value of FHLB Stock or FRB Stock due to restrictions placed on their transferability. As such, these instruments are carried at cost.
	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). Discounted cash flows are calculated using spread to swap and LIBOR curves that are updated to incorporate loss severities, volatility, credit spread and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations. Our municipal securities valuations are supported by analysis prepared by an independent third party. Their approach to determining fair value involves using recently executed transactions for similar securities and market quotations for similar securities. As these securities are not rated by the rating agencies and trading volumes are thin, it was determined that these were valued using Level 2 inputs.
	Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2).
	Loans: For variable-rate loans that reprice frequently and have no significant changes in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans and other consumer loans are estimated using the quoted market prices for securities backed by similar loans, adjusted for differences in loan characteristics. The fair value of other types of loans and leases is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers of similar credit ratings quality. Fair value for impaired loans and leases are estimated using discounted cash flow analysis or underlying collateral values, where applicable. The fair value may not approximate the exit price.
	Impaired Loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for loan losses. For collateral dependent loans, fair value is commonly 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.
	Other Real Estate Owned: 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. 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.
	Appraisals for both collateral-dependent impaired loans and other real estate owned are performed annually 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 Special Assets 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 most recent analysis performed indicated that a discount of approximately 17% should be applied.
	Loans Held For Sale: Fair value for loans originated to be held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2). Fair value of loans transferred to held for sale is determined using the carrying amount of the loans before they were transferred to loans held for sale net of any allowance for loan and lease loss, resulting in a Level 3 fair value classification.
	Accrued interest receivable: The carrying value of accrued interest receivable approximates fair value.
	Deposit liabilities: The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value for fixed-rate certificates of deposit is estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregate expected maturities on time deposits.
	Federal funds purchased and securities sold under agreements to repurchase: These borrowings generally mature in 90 days or less and, accordingly, the carrying amount reported in the consolidated balance sheets approximates fair value.
	Accrued interest payable: The carrying value of accrued interest payable approximates fair value.
	Other borrowings: Other borrowings carrying amount reported in the consolidated balance sheets approximates fair value.
	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:

At March 31, 2015, the Company also had assets and liabilities measured at fair value on a non-recurring basis. Items measured at fair value on a non-recurring basis include other real estate owned (OREO), and collateral-dependent impaired loans. Such measurements were determined utilizing Level 3 inputs.
The following tables presents the carrying value and associated valuation allowance of those assets measured at fair value on a non-recurring basis.

For the three month period ended March 31, 2015, the Company decreased its valuation allowance on $3.8 million of other real estate owned. The Company recorded write-downs on other real estate owned of $143 thousand and $309 thousand during the three months ended March 31, 2015 and 2014, respectively. For collateral-dependent loans, a $116 thousand provision for loan loss was recorded during the three months ended March 31, 2015. Zero provision for loan loss was recorded during the three months ended March 31, 2014. Any changes in the valuation allowance for a collateral-dependent loan are included in the allowance analysis and may result in additional provision expense.
There have been no transfers into or out of Level 3 during 2015 or 2014. There were no transfers between Level 1 and Level 2 during 2015 or 2014.
For loans transferred to held for sale the carrying amount was estimated by the carrying amount of the loans before they were transferred to loans held for sale, net of of any associated allowance for loan and lease loss.
For impaired loans and OREO properties, the Company utilizes independent, third-party appraisals to determine fair value. Independent appraisals are ordered at least annually. As part of the normal appraisal process, the appraisers generally provide the appraised value using one of following techniques: the sales comparison approach, the income approach or a combination thereof.  Under the sales comparison approach, the appraiser may make certain adjustments from the sold property to the appraised property, including, but not limited to, differences in square footage, lot size, absorption rates or location. As of March 31, 2015, the adjustments between the appraised property and the comparison property range from (72.4)% to 175.2% with a weighted average adjustment of (11.7)%. Under the income approach, the appraiser may make certain adjustments including, but not limited to, capitalization rates and differences in operating income expectations.  The Company's current third-party appraisals provided capitalization rates up to 10.0% with a weighted average of 9.2%. The Company's current third-party appraisals do not provide a range of adjustments to net operating income expectations. The Company monitors the realization rate between proceeds received and appraised value for all sold OREO properties.  This discount, defined as the weighted average percentage difference between appraised values and proceeds, is then applied to all remaining appraisals associated with impaired loans and OREO properties.  The Company monitors and applies this adjustment to the Company's Level 3 properties. The weighted average discount is approximately 17.0% as of March 31, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES
	The Company is party to credit related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and the issuance of financial guarantees in the form of financial and performance standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets.
	The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company follows the same credit policies in making commitments as they do for on-balance-sheet instruments.
	The Company’s maximum exposure to credit risk for unfunded loan commitments and standby letters of credit at March 31, 2015, December 31, 2014 and March 31, 2014 was as follows:
		March 31,		December 31, 2014		March 31,

	Commitments to extend credit - fixed rate	$	42,033	$	37,819	$	38,163
	Commitments to extend credit - variable rate	112,866		94,568		92,082
	Total commitments to extend credit	$	154,899	$	132,387	$	130,245
	Standby letters of credit	$	3,428	$	3,272	$	3,389
	Commitments to extend credit are agreements to lend to customers. Standby letters of credit are contingent commitments issued by the Company to guarantee performance of a customer to a third party under a contractual non-financial obligation for which it receives a fee. Financial standby letters of credit represent a commitment to guarantee customer repayment of an outstanding loan or debt instrument. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company on extension of credit, is based on management’s credit evaluation. Collateral held varies but may include accounts receivable, inventory, property and equipment and income-producing commercial properties.
	The Company is subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, the Company is subject to regulatory examinations, information gathering requests, inquiries, and investigations. The Company establishes accruals for litigation and regulatory matters when those matters present loss contingencies that the Company determines to be both probable and reasonably estimable. Based on current knowledge, advice of counsel and available insurance coverage, management does not believe that liabilities arising from legal claims, if any, will have a material adverse effect on the Company’s consolidated financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters, the early stage of various legal proceedings, and the indeterminate amount of damages sought in some of these matters, it is possible that the ultimate resolution of these matters, if unfavorable, could be material to the Company’s results of operations for any particular period.
	The Company intends to vigorously pursue all available defenses to these claims. There are significant uncertainties involved in any litigation. Although the ultimate outcome of these lawsuits cannot be ascertained at this time, based upon information that presently is available to it, management is unable to predict the outcome of these cases and cannot determine the probability of an adverse result or reasonably estimate a range of potential loss, if any. In addition, management is unable to estimate a range of reasonably possible losses with respect to these claims.
	Two putative shareholder class action lawsuits have been filed in connection with the Merger.  Knutson v. First Security Group, Inc. et al., filed April 15, 2015 in the Chancery Court for Hamilton County, Tennessee, names First Security, the members of its board of directors, and Atlantic Capital as defendants.  Meade v. Kramer, et al., filed in the Chancery Court for Hamilton County, Tennessee on April 24, 2015, names First Security, the members of its board of directors, FSGBank, N.A., Atlantic Capital and Atlantic Capital Bank as defendants.  Each of these complaints alleges, among other things, that the First Security directors breached their fiduciary duties in connection with the negotiation and approval of the Merger Agreement and that the other named defendants aided and abetted those alleged breaches of fiduciary duties.  Among other relief, the plaintiffs seek to enjoin the consummation of the Merger.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS
	Accounting Standards Update 2014-04, Receivables - Troubled Debt Restructurings by Creditors - Reclassification of Residual Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. In January 2014, the FASB amended this existing guidance to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical repossession of residential real estate property collateralizing a consumer mortgage loan, upon either: 1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or 2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through similar legal agreement. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2014. The adoption of this standard did not have a material effect on the Company's operating results or financial condition.
	In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers." This update is a joint project with the International Accounting Standards Board initiated to clarify the principles for recognizing revenue and to develop a common revenue standard that is meant to remove inconsistencies and weaknesses in revenue requirements, provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices, provide more useful information to users of financial statements and simplify the preparation of financial statements. The guidance in this update supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition" and most industry-specific guidance throughout the Industry Topics of Codification. This update is effective for annual and interim periods beginning after December 15, 2017. The Company is evaluating the impact of this update and does not believe it will have a significant impact to the Company's operating results or financial condition.

	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair statement of financial condition and the results of operations have been included. All such adjustments were of a normal recurring nature. Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net loss or shareholders’ equity.
	The consolidated financial statements include the accounts of First Security Group, Inc. ("First Security" , "FSG" or the "Company") and FSGBank, N.A. ("FSGBank" or the "Bank"), its wholly owned subsidiary bank. All significant intercompany balances and transactions have been eliminated.
	Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or any other period. These interim financial statements should be read in conjunction with the Company’s latest annual consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
Fair Value Measurements	FAIR VALUE MEASUREMENTS
	The authoritative accounting guidance for fair value measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.
	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 can 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 company's own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2015, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
	The Company used the following methods and significant assumptions to estimate fair value:
	Cash and cash equivalents: The carrying value of cash and cash equivalents approximates fair value.
	Interest bearing deposits in banks: The carrying amounts of interest bearing deposits in banks approximate fair value.
	Federal Home Loan Bank Stock and Federal Reserve Bank Stock: It is not practical to determine the fair value of FHLB Stock or FRB Stock due to restrictions placed on their transferability. As such, these instruments are carried at cost.
	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). Discounted cash flows are calculated using spread to swap and LIBOR curves that are updated to incorporate loss severities, volatility, credit spread and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations. Our municipal securities valuations are supported by analysis prepared by an independent third party. Their approach to determining fair value involves using recently executed transactions for similar securities and market quotations for similar securities. As these securities are not rated by the rating agencies and trading volumes are thin, it was determined that these were valued using Level 2 inputs.
	Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2).
	Loans: For variable-rate loans that reprice frequently and have no significant changes in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans and other consumer loans are estimated using the quoted market prices for securities backed by similar loans, adjusted for differences in loan characteristics. The fair value of other types of loans and leases is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers of similar credit ratings quality. Fair value for impaired loans and leases are estimated using discounted cash flow analysis or underlying collateral values, where applicable. The fair value may not approximate the exit price.
	Impaired Loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for loan losses. For collateral dependent loans, fair value is commonly 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.
	Other Real Estate Owned: 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. 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.
	Appraisals for both collateral-dependent impaired loans and other real estate owned are performed annually 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 Special Assets 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 most recent analysis performed indicated that a discount of approximately 17% should be applied.
	Loans Held For Sale: Fair value for loans originated to be held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2). Fair value of loans transferred to held for sale is determined using the carrying amount of the loans before they were transferred to loans held for sale net of any allowance for loan and lease loss, resulting in a Level 3 fair value classification.
	Accrued interest receivable: The carrying value of accrued interest receivable approximates fair value.
	Deposit liabilities: The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value for fixed-rate certificates of deposit is estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregate expected maturities on time deposits.
	Federal funds purchased and securities sold under agreements to repurchase: These borrowings generally mature in 90 days or less and, accordingly, the carrying amount reported in the consolidated balance sheets approximates fair value.
	Accrued interest payable: The carrying value of accrued interest payable approximates fair value.
	Other borrowings: Other borrowings carrying amount reported in the consolidated balance sheets approximates fair value.

For the three month period ended March 31, 2015, the Company decreased its valuation allowance on $3.8 million of other real estate owned. The Company recorded write-downs on other real estate owned of $143 thousand and $309 thousand during the three months ended March 31, 2015 and 2014, respectively. For collateral-dependent loans, a $116 thousand provision for loan loss was recorded during the three months ended March 31, 2015. Zero provision for loan loss was recorded during the three months ended March 31, 2014. Any changes in the valuation allowance for a collateral-dependent loan are included in the allowance analysis and may result in additional provision expense.
There have been no transfers into or out of Level 3 during 2015 or 2014. There were no transfers between Level 1 and Level 2 during 2015 or 2014.
For loans transferred to held for sale the carrying amount was estimated by the carrying amount of the loans before they were transferred to loans held for sale, net of of any associated allowance for loan and lease loss.
For impaired loans and OREO properties, the Company utilizes independent, third-party appraisals to determine fair value. Independent appraisals are ordered at least annually. As part of the normal appraisal process, the appraisers generally provide the appraised value using one of following techniques: the sales comparison approach, the income approach or a combination thereof.  Under the sales comparison approach, the appraiser may make certain adjustments from the sold property to the appraised property, including, but not limited to, differences in square footage, lot size, absorption rates or location. As of March 31, 2015, the adjustments between the appraised property and the comparison property range from (72.4)% to 175.2% with a weighted average adjustment of (11.7)%. Under the income approach, the appraiser may make certain adjustments including, but not limited to, capitalization rates and differences in operating income expectations.  The Company's current third-party appraisals provided capitalization rates up to 10.0% with a weighted average of 9.2%. The Company's current third-party appraisals do not provide a range of adjustments to net operating income expectations. The Company monitors the realization rate between proceeds received and appraised value for all sold OREO properties.  This discount, defined as the weighted average percentage difference between appraised values and proceeds, is then applied to all remaining appraisals associated with impaired loans and OREO properties.  The Company monitors and applies this adjustment to the Company's Level 3 properties. The weighted average discount is approximately 17.0% as of March 31, 2015.

Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS
	Accounting Standards Update 2014-04, Receivables - Troubled Debt Restructurings by Creditors - Reclassification of Residual Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. In January 2014, the FASB amended this existing guidance to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical repossession of residential real estate property collateralizing a consumer mortgage loan, upon either: 1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or 2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through similar legal agreement. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2014. The adoption of this standard did not have a material effect on the Company's operating results or financial condition.
	In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers." This update is a joint project with the International Accounting Standards Board initiated to clarify the principles for recognizing revenue and to develop a common revenue standard that is meant to remove inconsistencies and weaknesses in revenue requirements, provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices, provide more useful information to users of financial statements and simplify the preparation of financial statements. The guidance in this update supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition" and most industry-specific guidance throughout the Industry Topics of Codification. This update is effective for annual and interim periods beginning after December 15, 2017. The Company is evaluating the impact of this update and does not believe it will have a significant impact to the Company's operating results or financial condition.
