Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (In Thousands, Except Share Data) Nature of Operations : Renasant Corporation (referred to herein as the “Company”) owns and operates Renasant Bank (“Renasant Bank” or the “Bank”) and Renasant Insurance, Inc. The Company offers a diversified range of financial, fiduciary and insurance services to its retail and commercial customers through its subsidiaries and full service offices located throughout north and central Mississippi, Tennessee, north and central Alabama, north Georgia and Florida. Use of Estimates : The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Consolidation : In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic (“ASC”) 810, “Consolidation” (“ASC 810”), a company’s consolidated financial statements are required to include subsidiaries in which the company has a controlling financial interest. The accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements include the accounts of the Company and its consolidated subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to the current year presentation. The Company is not the primary beneficiary of any variable interest entity as defined by ASC 810. Cash and Cash Equivalents : The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Securities : Debt securities are classified as held to maturity when purchased if management has the positive intent and ability to hold the securities to maturity. Held to maturity securities are stated at amortized cost. Securities not classified as held to maturity or trading are classified as available for sale. Presently, the Company has no intention of establishing a trading classification. Available for sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income within shareholders’ equity. The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts. Such amortization and accretion is included in interest income from securities. Dividend income is included in interest income from securities. Realized gains and losses on sales of securities are reflected under the line item “Net gains on sales of securities” on the Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. The Company evaluates its investment portfolio for other-than-temporary-impairment (“OTTI”) on a quarterly basis in accordance with ASC 320, “Investments - Debt and Equity Securities.” Impairment is assessed at the individual security level. The Company considers an investment security impaired if the fair value of the security is less than its cost or amortized cost basis. Impairment is considered to be other-than-temporary if the Company intends to sell the investment security or if the Company does not expect to recover the entire amortized cost basis of the security before the Company is required to sell the security or the security’s maturity. When impairment of an equity security is considered to be other-than-temporary, the security is written down to its fair value and an impairment loss is recorded as a loss within noninterest income in the Consolidated Statements of Income. When impairment of a debt security is considered to be other-than-temporary, the security is written down to its fair value. The amount of OTTI recorded as a loss within noninterest income depends on whether an entity intends to sell the debt security and whether it is more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis. If an entity intends to, or has decided to, sell the debt security or more likely than not will be required to sell the security before recovery of its amortized cost basis, OTTI must be recognized in earnings in an amount equal to the entire difference between the security’s amortized cost basis and its fair value. If an entity does not intend to sell the debt security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, OTTI is separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss is recognized in earnings and is calculated as the difference between the estimate of discounted future cash flows and the amortized cost basis of the security. A number of qualitative and quantitative factors, including but not limited to the financial condition of the underlying issuer and current and projected deferrals or defaults, are considered by management in the estimate of the discounted future cash flows. The remaining difference between the fair value and the amortized cost basis of the security is considered the amount related to other market factors and is recognized in other comprehensive income, net of applicable taxes. Furthermore, debt securities may be transferred to a nonaccrual status where the recognition of investment interest is discontinued. A number of qualitative factors, including but not limited to the financial condition of the underlying issuer and current and projected deferrals or defaults, are considered by management in the determination of whether the debt security should be transferred to nonaccrual status. The interest on these nonaccrual investment securities is accounted for on the cash-basis method until the debt security qualifies for return to accrual status. See Note C, “Securities,” for further details regarding the Company’s securities portfolio. Securities Sold Under Agreements to Repurchase : Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party. Mortgage Loans Held for Sale : Mortgage loans held for sale represent residential mortgage loans held for sale. The Company has elected to carry these loans at fair value as permitted under the guidance in ASC 825, “Financial Instruments” (“ASC 825”). Mortgage loans held for sale are classified separately on the Consolidated Balance Sheets. Gains and losses are realized at the time consideration is received and all other criteria for sales treatment have been met. These realized and unrealized gains and losses are classified under the line item “Mortgage banking income” on the Consolidated Statements of Income. Loans and the Allowance for Loan Losses : Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses and any deferred fees or costs on originated loans. Renasant Bank defers certain nonrefundable loan origination fees as well as the direct costs of originating or acquiring loans. The deferred fees and costs are then amortized over the term of the note for all loans with payment schedules. Those loans with no payment schedule are amortized using the interest method. The amortization of these deferred fees is presented as an adjustment to the yield on loans. Interest income is accrued on the unpaid principal balance. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, the recognition of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer and other retail loans are typically charged-off no later than the time the loan is 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Loans may be placed on nonaccrual regardless of whether or not such loans are considered past due. All interest accrued for the current year, but not collected, for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Impairment is measured on a loan-by-loan basis for commercial and construction loans above a minimum dollar amount threshold by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are evaluated collectively for impairment. When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal. Once the recorded balance has been reduced to zero, future cash receipts are applied to interest income, to the extent any interest has been foregone, and then they are recorded as recoveries of any amounts previously charged-off. For impaired loans, a specific reserve is established to adjust the carrying value of the loan to its estimated net realizable value. Restructured loans are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition and are performing in accordance with the new terms. Such concessions may include reduction in interest rates or deferral of interest or principal payments. In evaluating whether to restructure a loan, management analyzes the long-term financial condition of the borrower, including guarantor and collateral support, to determine whether the proposed concessions will increase the likelihood of repayment of principal and interest. Restructured loans that are not performing in accordance with their restructured terms that are either contractually 90 days past due or have been placed on nonaccrual status are reported as nonperforming loans. See Note D, “Loans and the Allowance for Loan Losses,” for disclosures regarding the Company’s past due and nonaccrual loans, impaired loans and restructured loans. The allowance for loan losses is maintained at a level believed adequate by management to absorb probable credit losses inherent in the entire loan portfolio. The appropriate level of the allowance is based on an ongoing analysis of the loan portfolio and represents an amount that management deems adequate to provide for inherent losses, including collective impairment as recognized under ASC 450, “Contingencies”. Collective impairment is calculated based on loans grouped by grade. Another component of the allowance is losses on loans assessed as impaired under ASC 310, “Receivables” (“ASC 310”). The balance of these loans and their related allowance is included in management’s estimation and analysis of the allowance for loan losses. Management and the internal loan review staff evaluate the adequacy of the allowance for loan losses quarterly. The allowance for loan losses is evaluated based on a continuing assessment of problem loans, the types of loans, historical loss experience, new lending products, emerging credit trends, changes in the size and character of loan categories and other factors, including its risk rating system, regulatory guidance and economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance for loan losses is established through a provision for loan losses charged to earnings resulting from measurements of inherent credit risk in the loan portfolio and estimates of probable losses or impairments of individual loans. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Business Combinations, Accounting for Acquired Loans and Related Assets : Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations” (“ASC 805”). Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date and are recognized separately from goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Acquisition costs incurred by the Company are expensed as incurred. Loans acquired in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit-impaired. Acquired credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality, in accordance with ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC 310-30”), and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. Increases in expected cash flows to be collected on these loans are recognized as an adjustment of the loan’s yield over its remaining life, while decreases in expected cash flows are recognized as an impairment. In connection with the acquisition of specified assets and assumption of specified liabilities of Crescent Bank and Trust (“Crescent”) in July 2010 and American Trust Bank (“American Trust”) in February 2011, the Bank entered into loss-share agreements with the Federal Deposits Insurance Corporation (“FDIC”). Furthermore, in connection with the acquisition of Heritage, the Bank entered into two loss-sharing agreements with the FDIC which covered Citizens Bank of Effingham (“Citizens”) and First Southern National Bank (“First Southern”). Acquired loans covered under loss-share agreements with the FDIC are recorded, as of their respective acquisition dates, at fair value. The fair value of these loans represents the expected discounted cash flows to be received over the lives of the loans, taking into account the Company’s estimate of future credit losses on the loans. These loans are initially excluded from the calculation of the allowance for loan losses because the fair value measurement incorporates an estimate of losses on acquired loans. The Company monitors future cash flows on these loans; to the extent future cash flows deteriorate below initial projections, the Company reserves for these loans in the allowance for loan losses through the provision for loan losses. The Company recorded a provision for loan losses of $62 and $722 on account of the loans covered under loss-share agreements during the years ended December 31, 2015 and 2014 , respectively. In these Notes to Consolidated Financial Statements, the Company refers to loans acquired and subject to the loss-share agreements as “covered loans” or “loans covered under loss-share agreements” and loans acquired that are not subject to the loss-share agreements as “acquired non-covered loans” or “loans not covered under loss-share agreements.” As part of the loan portfolio and other real estate owned fair value estimation in connection with FDIC-assisted acquisitions, a FDIC loss-share indemnification asset is established, which represents the present value of the estimated losses on covered assets to be reimbursed by the FDIC. The estimated losses are based on the same cash flow estimates used in determining the fair value of the covered assets. The FDIC loss-share indemnification asset is reduced as losses are recognized on covered assets and loss-share payments are received from the FDIC. Realized losses in excess of estimates as of the date of the acquisition increase the FDIC loss-share indemnification asset. Conversely, when realized losses are less than these estimates, the portion of the FDIC loss-share indemnification asset no longer expected to result in a payment from the FDIC is amortized into interest income using the effective interest method. Changes in the FDIC loss-share indemnification asset were as follows: 2015 2014 Balance at January 1 $ 12,516 $ 26,273 Additions through acquisition 2,673 — Realized losses in excess of initial estimates on: Loans 872 6,293 OREO 362 2,593 Reimbursable expenses 1,170 335 Amortization (4,865 ) (9,195 ) Reimbursements received from the FDIC (5,579 ) (13,783 ) Balance at December 31 $ 7,149 $ 12,516 Premises and Equipment : Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily by use of the straight-line method for furniture, fixtures, equipment, autos and premises. The annual provisions for depreciation have been computed primarily using estimated lives of forty years for premises, seven years for furniture and equipment and three to five years for computer equipment and autos. Leasehold improvements are expensed over the period of the leases or the estimated useful life of the improvements, whichever is shorter. Other Real Estate Owned : Other real estate owned consists of properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure. These properties are initially recorded into other real estate at fair market value less cost to sell and are subsequently carried at the lower of cost or fair market value based on appraised value less estimated selling costs. Losses arising at the time of foreclosure of properties are charged against the allowance for loan losses. Reductions in the carrying value subsequent to acquisition are charged to earnings and are included under the line item “Other real estate owned” in the Consolidated Statements of Income. Mortgage Servicing Rights : The Company retains the right to service certain mortgage loans that it sells to secondary market investors. These mortgage servicing rights, included in “Other assets” on the Consolidated Balance Sheets, are recognized as a separate asset on the date the corresponding mortgage loan is sold. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income. These servicing rights are carried at the lower of amortized cost or fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, prepayment speeds, market discount rates, servicing costs, and other factors. Mortgage servicing rights were carried at amortized cost at December 31, 2015 and 2014 , respectively. Impairment losses on mortgage servicing rights are recognized to the extent by which the unamortized cost exceeds fair value. No impairment losses on mortgage servicing rights were recognized in earnings for the years ended December 31, 2015 , 2014 or 2013 . Goodwill and Other Intangible Assets : Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangibles with finite lives are amortized over their estimated useful lives. Goodwill and other intangible assets are subject to impairment testing annually or more frequently if events or circumstances indicate possible impairment. Goodwill is assigned to the Company’s reporting segments. Fair values of reporting segments are determined using either discounted cash flow analyses based on internal financial forecasts or, if available, market-based valuation multiples for comparable businesses. Other intangible assets, consisting of core deposit intangibles, are reviewed for events or circumstances which could impact the recoverability of the intangible asset, such as a loss of core deposits, increased competition or adverse changes in the economy. No impairment was identified for the Company’s goodwill or its other intangible assets as a result of the testing performed during 2015 , 2014 or 2013 . Bank-Owned Life Insurance : Bank-owned life insurance (“BOLI”) is an institutionally-priced insurance product that is specifically designed for purchase by insured depository institutions. The Company has purchased such insurance policies on certain employees, with Renasant Bank being listed as the primary beneficiary. The carrying value of BOLI is recorded at the cash surrender value of the policies, net of any applicable surrender charges. The carrying value of BOLI included in the Consolidated Balance Sheets under the line item “Other assets” at December 31, 2015 and 2014 was $141,067 and $112,597 , respectively. In connection with the acquisition of Heritage, the Company acquired BOLI with a cash surrender value of $25,297 at the acquisition date. Changes in the value of the cash surrender value of the policies are reflected under the line item “BOLI income” on the Consolidated Statements of Income. Insurance Agency Revenues : Renasant Insurance, Inc. is a full-service insurance agency offering all lines of commercial and personal insurance through major third-party insurance carriers. Commissions and fees are recognized when earned based on contractual terms and conditions of insurance policies with the insurance carriers. These commissions and fees are classified under the line item “Insurance commissions” on the Consolidated Statements of Income. Contingency fee income paid by the insurance carriers is recognized upon receipt and classified under the line item “Other noninterest income” on the Consolidated Statements of Income. Trust and Financial Services Revenues : The Company offers trust services as well as various alternative investment products, including annuities and mutual funds. Trust revenues are recognized on the accrual basis in accordance with the contractual terms of the trust. Commissions and fees from the sale of annuities and mutual funds are recognized when earned based on contractual terms with the third party broker-dealer. These commissions and fees are classified under the line item “Wealth management revenue” on the Consolidated Statements of Income. Income Taxes : Income taxes are accounted for under the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. It is the Company’s policy to recognize interest and penalties, if incurred, related to unrecognized tax benefits in income tax expense. The Company and its subsidiaries file a consolidated federal income tax return. Renasant Bank provides for income taxes on a separate-return basis and remits to the Company amounts determined to be currently payable. Deferred income taxes, included in “Other assets” on the Consolidated Balance Sheets, reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes that the Company and its subsidiaries will realize a substantial majority of the deferred tax assets. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized through a charge to income tax expense. Fair Value Measurements : ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), provides guidance for using fair value to measure assets and liabilities and also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to a valuation based on quoted prices in active markets for identical assets and liabilities (Level 1), moderate priority to a valuation based on quoted prices in active markets for similar assets and liabilities and/or based on assumptions that are observable in the market (Level 2), and the lowest priority to a valuation based on assumptions that are not observable in the market (Level 3). See Note R, “Fair Value Measurements,” for further details regarding the Company’s methods and assumptions used to estimate the fair values of the Company’s financial assets and liabilities. Derivative Instruments and Hedging Activities : The Company utilizes derivative financial instruments as part of its ongoing efforts to manage its interest rate risk exposure. Derivative financial instruments are included in the Consolidated Balance Sheets line item “Other assets” or “Other liabilities” at fair value in accordance with ASC 815, “Derivatives and Hedging.” Cash flow hedges are utilized to mitigate the exposure to variability in expected future cash flows or other types of forecasted transactions. For the Company’s derivatives designated as cash flow hedges, changes in the fair value of cash flow hedges are, to the extent that the hedging relationship is effective, recorded as other comprehensive income and are subsequently recognized in earnings at the same time that the hedged item is recognized in earnings. The ineffective portions of the changes in fair value of the hedging instruments are immediately recognized in earnings. The assessment of the effectiveness of the hedging relationship is evaluated under the hypothetical derivative method. The Company also utilizes derivative instruments that are not designated as hedging instruments. The Company enters into interest rate cap and/or floor agreements with its customers and then enters into an offsetting derivative contract position with other financial institutions to mitigate the interest rate risk associated with these customer contracts. Because these derivative instruments are not designated as hedging instruments, changes in the fair value of the derivative instruments are recognized currently in earnings. The Company enters into interest rate lock commitments on certain residential mortgage loans with its customers to mitigate the interest rate risk associated with the commitments to fund fixed-rate mortgage loans. Under such commitments, interest rates for a mortgage loan are typically locked in for up to forty-five days with the customer. These interest rate lock commitments are recorded at fair value in the Company’s Consolidated Balance Sheets. Gains and losses arising from changes in the valuation of the commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income. The Company utilizes two methods to deliver mortgage loans to be sold to an investor. Under a “best efforts” sales agreement, the Company enters into a sales agreement with an investor in the secondary market to sell the loan when an interest rate lock commitment is entered into with a customer, as described above. Under a “best efforts” sales agreement, the Company is obligated to sell the mortgage loan to the investor only if the loan is closed and funded. Thus, the Company will not incur any liability to an investor if the mortgage loan commitment in the pipeline fails to close. Under a mandatory delivery sales agreement, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price and delivery date. Penalties are paid to the investor should the Company fail to satisfy the contract. Mandatory delivery mortgage loan commitments are recorded at fair value in the Company’s Consolidated Balance Sheets. Gains and losses arising from changes in the valuation of these commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income. Treasury Stock : Treasury stock is recorded at cost. Shares held in treasury are not retired. Retirement Plans : The Company sponsors a noncontributory pension plan and provides retiree heath care benefits for certain employees. Our independent actuary firm prepares actuarial valuations of our pension cost and obligation under ASC 715, “Compensation – Retirement Benefits” ("ASC 715") using assumptions and estimates derived in accordance with the guidance set forth in ASC 715. Expense related to the plans is included under the line item "Salaries and employee benefits" on the Consolidated Statements of Income. Actuarial gains and losses are recognized in accumulated other comprehensive income, net of tax, until they are amortized as a component of plan expense. Stock-Based Compensation : Compensation expense for option grants and restricted stock awards is determined based on the estimated fair value of the stock options and restricted stock on the applicable grant or award date. Further, compensation expense is based on an estimate of the number of option grants expected to vest and is recognized over the option’s vesting period. The Company did not estimate any option forfeitures for 2015 , 2014 or 2013 due to the low historical forfeiture rate. Expense associated with the Company’s stock-based compensation is included under the line item “Salaries and employee benefits” on the Consolidated Statements of Income. The Company recognizes compensation expense for all share-based payments to employees in accordance with ASC 718, “Compensation – Stock Compensation.” See Note N, “Employee Benefit and Deferred Compensation Plans,” for further details regarding the Company’s stock-based compensation. Earnings Per Common Share : Basic net income per common share is calculated by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted net income per common share reflects the pro forma dilution assuming outstanding stock options were exercised into common shares, calculated in accordance with the treasury stock method. See Note W, “Net Income Per Common Share,” for the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations. Subsequent Events : The Company has evaluated, for consideration of recognition or disclosure, subsequent events that have occurred through the date of issuance of its financial statements, and has determined that no significant events occurred after December 31, 2015 but prior to the issuance of these financial statements that would have a material impact on its Consolidated Financial Statements. Impact of Recently-Issued Accounting Standards and Pronouncements : In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20) –Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for interim and annual periods beginning after December 15, 2015. ASU 2015-01 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures. In February 2015, the FASB issued ASU 2015-02, “Cons

Under the terms of the agreement, KeyWorth will be merged with and into Renasant Bank, with Renasant Bank continuing as the surviving institution in the Merger. According to the terms of the merger agreement, each KeyWorth common shareholder will have the right to receive 0.4494 shares of Renasant common stock for each share of KeyWorth common stock, and the merger is expected to qualify as a tax-free reorganization for KeyWorth shareholders. KeyWorth operates six offices in the Atlanta metropolitan area and as of December 31, 2015, had approximately $407,782 in total assets, which included approximately $252,092 in total loans, and approximately $355,117 in total deposits. The acquisition is expected to close in the second quarter of 2016 and is subject to KeyWorth shareholder approval and other customary conditions set forth in the merger agreement. Acquisition of Heritage Financial Group, Inc. Effective July 1, 2015, the Company completed its acquisition by merger with Heritage Financial Group, Inc. (“Heritage”) in a transaction valued at $295,380 . The Company issued 8,635,879 shares of common stock and paid $5,915 to Heritage stock option holders for 100% of the voting equity interest in Heritage. At closing, Heritage merged with and into the Company, with the Company surviving the merger. On the same date, HeritageBank of the South, Heritage’s wholly-owned subsidiary (“HeritageBank”), was merged into Renasant Bank. On July 1, 2015, Heritage operated 48 banking, mortgage and investment offices in Alabama, Georgia and Florida. The Company recorded approximately $183,438 in intangible assets which consist of goodwill of $171,182 and a core deposit intangible of $12,256 . Goodwill resulted from a combination of revenue enhancements from expansion into new markets and efficiencies resulting from operational synergies. The fair value of the core deposit intangible is being amortized on an accelerated basis over the estimated useful life, currently expected to be approximately 10 years. The goodwill is not deductible for income tax purposes. The following table summarizes the allocation of purchase price to assets and liabilities acquired in connection with the Company’s acquisition of Heritage based on their fair values on July 1, 2015. The Company is finalizing the fair value of certain assets and liabilities. As a result, the adjustments included in the following table are preliminary and may change.

The following table summarizes the fair value of assets acquired and liabilities assumed at acquisition date in connection with the merger with Heritage. The Company is finalizing the fair value of certain assets and liabilities. As a result, the adjustments included in the following table are preliminary and may change. Cash and cash equivalents $ 38,626 Securities 177,849 Loans, including mortgage loans held for sale, net of unearned income 1,460,242 Premises and equipment 42,164 Other real estate owned 9,972 Intangible assets 183,438 Other assets 102,591 Total assets 2,014,882 Deposits 1,375,354 Borrowings 314,656 Other liabilities 29,492 Total liabilities 1,719,502 The following unaudited pro forma combined condensed consolidated financial information presents the results of operations for the twelve months ended December 31, 2015 and 2014 of the Company as though the merger with Heritage had been completed as of January 1, 2014. The unaudited estimated pro forma information combines the historical consolidated results of Heritage with the Company’s historical consolidated results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the periods presented. The pro forma information is not indicative of what would have occurred had the acquisition taken place on January 1, 2014. The pro forma information does not include the effect of any cost-saving or revenue-enhancing strategies. Merger expenses are reflected in the period in which they were incurred. Twelve Months Ended December 31, 2015 2014 Interest income $ 301,226 $ 305,868 Interest expense 21,858 29,575 Net interest income 279,368 276,293 Provision for loan and lease losses 5,050 7,736 Noninterest income 135,379 107,218 Noninterest expense 309,803 270,868 Income before income taxes 99,894 104,907 Income taxes 31,772 32,723 Net income $ 68,122 $ 72,184 Earnings per share: Basic $ 1.69 $ 1.80 Diluted $ 1.68 $ 1.79 The Company’s consolidated financial statements as of and for the year ended December 31, 2015 include the impact of Heritage’s operations since the acquisition date. Due to the system conversion during the third quarter of 2015 and the integration of Heritage’s operating activities into the Company’s existing operations, historical reporting for Heritage operations is impracticable, and, therefore, disclosure of the amounts of revenue and expenses of Heritage included in the Company’s Consolidated Statement of Income since the acquisition date is impracticable. Acquisition of First M&F Corporation On September 1, 2013, the Company completed its acquisition by merger of First M&F Corporation (“First M&F”), a bank holding company headquartered in Kosciusko, Mississippi, and the parent of Merchants and Farmers Bank, a Mississippi banking corporation. On the same date, Merchants and Farmers Bank was merged into Renasant Bank. On August 31, 2013, First M&F operated 43 banking and insurance locations in Mississippi, Alabama and Tennessee. The Company issued 6,175,576 shares of its common stock for 100% of the voting equity interests in First M&F. The aggregate transaction value, including the dilutive impact of First M&F’s stock based compensation assumed by the Company, was $156,845 . The Company recorded approximately $115,159 in intangible assets which consist of goodwill of $90,127 and core deposit intangible of $25,032 . Goodwill resulted from a combination of revenue enhancements from expansion into new markets and efficiencies resulting from operational synergies. The fair value of the core deposit intangible is being amortized on an accelerated basis over the estimated useful life, currently expected to be approximately 10 years. The goodwill is not deductible for income tax purposes. The Company assumed $30,928 in fixed/floating rate junior subordinated deferrable interest debentures payable to First M&F Statutory Trust I that mature in March 2036 . The acquired subordinated debentures require interest to be paid quarterly at a rate of 90-day LIBOR plus 1.33% . The fair value adjustment on the junior subordinated debentures of $12,371 is being amortized on a straight line basis over the remaining life.

Securities	Securities (In Thousands, Except Number of Securities) The amortized cost and fair value of securities held to maturity were as follows as of the dates presented: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2015 Obligations of other U.S. Government agencies and corporations $ 101,155 $ 26 $ (1,214 ) $ 99,967 Obligations of states and political subdivisions 357,245 16,636 (95 ) 373,786 $ 458,400 $ 16,662 $ (1,309 ) $ 473,753 December 31, 2014 Obligations of other U.S. Government agencies and corporations $ 125,081 $ 10 $ (2,915 ) $ 122,176 Obligations of states and political subdivisions 305,082 15,428 (198 ) 320,312 $ 430,163 $ 15,438 $ (3,113 ) $ 442,488 In light of the ongoing fiscal uncertainty in state and local governments, the Company analyzes its exposure to potential losses in its security portfolio on at least a quarterly basis. Management reviews the underlying credit rating and analyzes the financial condition of the respective issuers. Based on this analysis, the Company sold certain securities representing obligations of state and political subdivisions that were classified as held to maturity during 2013. The securities sold showed significant credit deterioration in that an analysis of the financial condition of the respective issuers showed the issuers were operating at net deficits with little to no financial cushion to offset future contingencies. The securities sold in 2013 had carrying values of $ 4,290 , and the Company recognized a net gain of $169 on the sales during the year ended December 31, 2013. No securities classified as held to maturity were sold during the years ended December 31, 2015 or December 31, 2014. The amortized cost and fair value of securities available for sale were as follows as of the dates presented: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2015 Obligations of other U.S. Government agencies and corporations $ 6,093 $ 126 $ (19 ) $ 6,200 Residential mortgage backed securities: Government agency mortgage backed securities 362,669 3,649 (1,778 ) 364,540 Government agency collateralized mortgage obligations 168,916 1,449 (2,305 ) 168,060 Commercial mortgage backed securities: Government agency mortgage backed securities 58,864 1,002 (107 ) 59,759 Government agency collateralized mortgage obligations 4,947 158 (1 ) 5,104 Trust preferred securities 24,770 — (5,301 ) 19,469 Other debt securities 18,899 468 (34 ) 19,333 Other equity securities 2,500 1,840 — 4,340 $ 647,658 $ 8,692 $ (9,545 ) $ 646,805 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2014 Obligations of other U.S. Government agencies and corporations $ 6,119 $ 147 $ (119 ) $ 6,147 Residential mortgage backed securities: Government agency mortgage backed securities 292,283 4,908 (832 ) 296,359 Government agency collateralized mortgage obligations 158,436 1,523 (2,523 ) 157,436 Commercial mortgage backed securities: Government agency mortgage backed securities 45,714 1,608 (137 ) 47,185 Government agency collateralized mortgage obligations 4,970 202 — 5,172 Trust preferred securities 26,400 137 (6,781 ) 19,756 Other debt securities 17,517 487 (74 ) 17,930 Other equity securities 2,331 1,268 — 3,599 $ 553,770 $ 10,280 $ (10,466 ) $ 553,584 During the year ended December 31, 2015, the Company sold its pooled trust preferred security XIII with a carrying value of $1,117 at the time of sale for net proceeds of $1,213 resulting in a gain of $96 . Furthermore, the Company sold certain investments acquired from Heritage shortly after acquisition with an aggregate carrying value of $7,231 at the time of sale for net proceeds of $7,231 , resulting in no gain or loss on the sale. During the same period in 2014 and 2013, the Company sold securities with a carrying value at the time of sale of $724 and $9,130 , respectively, for net proceeds of $1,099 and $9,015 , respectively, resulting in a gain of $375 and a loss of $115 , respectively.

Furthermore, even though a number of these securities have been in a continuous unrealized loss position for a period greater than twelve months, the Company has experienced an overall improvement in the fair value of its investment portfolio and is collecting principal and interest payments from the respective issuers as scheduled. As such, the Company did not record any other-than-temporary impairment for the years ended December 31, 2015 or 2014. The Company holds investments in pooled trust preferred securities that had a cost basis of $24,770 and $26,400 and a fair value of $19,469 and $19,756 at December 31, 2015 and 2014 , respectively. The investments in pooled trust preferred securities consist of three securities representing interests in various tranches of trusts collateralized by debt issued by over 250 financial institutions. Management’s determination of the fair value of each of its holdings in pooled trust preferred securities is based on the current credit ratings, the known deferrals and defaults by the underlying issuing financial institutions and the degree to which future deferrals and defaults would be required to occur before the cash flow for the Company’s tranches is negatively impacted. In addition, management continually monitors key credit quality and capital ratios of the issuing institutions. This determination is further supported by quarterly valuations, which are performed by third parties, of each security obtained by the Company. The Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments, before recovery of the investments’ amortized cost, which may be at maturity. At December 31, 2015 , management did not, and does not currently, believe such securities will be settled at a price less than the amortized cost of the investment, but the Company previously concluded that it was probable that there had been an adverse change in estimated cash flows for all three trust preferred securities and recognized credit related impairment losses on these securities in 2010 and 2011. For the years ended December 31, 2015 , 2014 , and 2013 , the Company determined the pooled trust preferred securities and their estimated cash flow were fairly valued, and no additional impairment was recognized during these periods. The Company’s analysis of the pooled trust preferred securities during the second quarter of 2015 supported a return to accrual status for one of the three securities (XXVI). During the second quarter of 2014, the Company’s analysis supported a return to accrual status for one of the other securities (XXIII). An observed history of principal and interest payments combined with improved qualitative and quantitative factors described above justified the accrual of interest on these securities. However, the remaining security (XXIV) is still in “payment in kind” status where interest payments are not expected until a future date and therefore, the qualitative and quantitative factors described above do not justify a return to accrual status at this time. As a result, pooled trust preferred security XXIV remains classified as a nonaccruing asset at December 31, 2015 , and investment interest is recorded on the cash-basis method until qualifying for return to accrual status.

The Company had no remaining availability under commitments to lend additional funds on these restructured loans at December 31, 2015 and six thousand dollars in remaining availability under commitments to lend additional funds on these restructured loans at December 31, 2014 . Credit Quality For commercial and commercial real estate secured loans, internal risk-rating grades are assigned by lending, credit administration or loan review personnel, based on an analysis of the financial and collateral strength and other credit attributes underlying each loan. Management analyzes the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the portfolio balances of commercial and commercial real estate secured loans. Loan grades range between 1 and 9 , with 1 being loans with the least credit risk. Loans that migrate toward the “Pass” grade (those with a risk rating between 1 and 4 ) or within the “Pass” grade generally have a lower risk of loss and therefore a lower risk factor. The “Watch” grade (those with a risk rating of 5 ) is utilized on a temporary basis for “Pass” grade loans where a significant risk-modifying action is anticipated in the near term. Loans that migrate toward the “Substandard” grade (those with a risk rating between 6 and 9 ) generally have a higher risk of loss and therefore a higher risk factor applied to those related loan balances. The following table presents the Company’s loan portfolio by risk-rating grades as of the dates presented: Pass Watch Substandard Total December 31, 2015 Commercial, financial, agricultural $ 465,185 $ 8,498 $ 1,734 $ 475,417 Real estate – construction 273,398 483 — 273,881 Real estate – 1-4 family mortgage 275,269 9,712 15,460 300,441 Real estate – commercial mortgage 1,968,352 27,175 20,683 2,016,210 Installment loans to individuals 51 — 5 56 Total $ 2,982,255 $ 45,868 $ 37,882 $ 3,066,005 December 31, 2014 Commercial, financial, agricultural $ 337,998 $ 5,255 $ 1,451 $ 344,704 Real estate – construction 150,683 855 — 151,538 Real estate – 1-4 family mortgage 122,608 6,079 11,479 140,166 Real estate – commercial mortgage 1,389,787 31,109 33,554 1,454,450 Installment loans to individuals 1,402 — — 1,402 Total $ 2,002,478 $ 43,298 $ 46,484 $ 2,092,260 For portfolio balances of consumer, consumer mortgage and certain other similar loan types, allowance factors are determined based on historical loss ratios by portfolio for the preceding eight quarters and may be adjusted by other qualitative criteria.

Distributions on the capital securities are payable quarterly at a rate per annum equal to the interest rate being earned by the trusts on the debentures held by the trusts. The capital securities are subject to mandatory redemption, in whole or in part, upon repayment of the debentures. The Company has entered into an agreement which fully and unconditionally guarantees the capital securities subject to the terms of the guarantee. The following table provides details on the debentures as of December 31, 2015 : Principal Amount Interest Rate Year of Maturity Amount Included in Tier 1 Capital PHC Statutory Trust I $ 20,619 3.09 % 2033 $ 20,000 PHC Statutory Trust II 31,959 2.38 2035 31,000 Heritage Financial Statutory Trust I 10,310 10.20 2031 10,000 Capital Bancorp Capital Trust I 12,372 2.10 2035 12,000 First M&F Statutory Trust I 30,928 1.84 2036 18,907 During 2003, the Company formed PHC Statutory Trust I to provide funds for the cash portion of the Renasant Bancshares, Inc. acquisition. The interest rate for PHC Statutory Trust I reprices quarterly equal to the three-month LIBOR at the determination date plus 285 basis points. In April 2012, the Company entered into an interest rate swap agreement effective March 17, 2014 , pursuant to which the Company receives a variable rate of interest based on the three-month LIBOR plus a spread of 2.85% and pays a fixed rate of interest of 5.49% . The debentures owned by PHC Statutory Trust I are currently redeemable at par. During 2005, the Company formed PHC Statutory Trust II to provide funds for the cash portion of the Heritage Financial Holding Corporation (“HFHC”) acquisition. The interest rate for PHC Statutory Trust II reprices quarterly equal to the three-month LIBOR at the determination date plus 187 basis points. The debentures owned by PHC Statutory Trust II are currently redeemable at par. In connection with the acquisition of HFHC, the Company assumed the debentures issued by Heritage Financial Statutory Trust I. The premium associated with the Company’s assumption of the debentures issued by Heritage Financial Statutory Trust I, which was fully amortized as of February 2015, had a carrying value of $27 at December 31, 2014 . The interest rate for Heritage Financial Statutory Trust I is fixed at 10.20% per annum. On or after February 22, 2021, the debentures owned by Heritage Financial Statutory Trust I may be redeemed at par. In connection with the acquisition of Capital Bancorp, Inc. (“Capital”) in 2007, the Company assumed the debentures issued to Capital Bancorp Capital Trust I. The discount associated with the Company’s assumption of the debentures issued to Capital Bancorp Capital Trust I was fully amortized during 2010. The interest rate for Capital Bancorp Capital Trust I reprices quarterly equal to the three-month LIBOR plus 150 basis points. In March 2012, the Company entered into an interest rate swap agreement effective March 31, 2014, whereby, beginning on the effective date, the Company will receive a variable rate of interest based on the three-month LIBOR plus a spread of 1.50% and pay a fixed rate of interest of 4.42% . The debentures owned by Capital Bancorp Capital Trust I are currently redeemable at par. In connection with the acquisition of First M&F, the Company assumed the debentures issued to First M&F Statutory Trust I. The discount associated with the Company’s assumption of the debentures issued to First M&F Statutory Trust I had a carrying value of $11,093 at December 31, 2015 and $11,641 at December 31, 2014. The discount is being amortized through March 2036. The interest for First M&F Statutory Trust I reprices quarterly equal to the three-month LIBOR plus a spread of 133 basis points. The Company also assumed from First M&F a pay-fixed, receive-floating interest rate swap, maturing on March 15, 2018, which calls for the Company to pay a fixed rate of 3.795% and receive a variable rate of three-month LIBOR plus a spread of 133 basis points on a quarterly basis. The debentures owned by First M&F Statutory Trust I are currently redeemable at par. The Company has classified $91,907 of the debentures described in the above paragraphs as Tier 1 capital. The Federal Reserve Board issued guidance in March 2005 providing more strict quantitative limits on the amount of securities, similar to the junior subordinated debentures issued or assumed by the Company, that are includable in Tier 1 capital. The new guidance, which became effective in March 2009, did not impact the amount of debentures the Company includes in Tier 1 capital. Furthermore, the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act have no effect on the treatment of these debentures as Tier 1 capital. For more information about the Company’s derivative financial instruments, see Note S, “Derivative Instruments.” The aggregate stated maturities of long-term debt outstanding at December 31, 2015 , are summarized as follows: 2016 $ 261 2017 — 2018 41,584 2019 2,269 2020 2,885 Thereafter 101,218 Total $ 148,217

Commitments, Contingent Liabilities and Financial Instruments with Off-Balance Sheet Risk	Commitments, Contingent Liabilities and Financial Instruments with Off-Balance Sheet Risk (In Thousands) Loan commitments are made to accommodate the financial needs of the Company’s customers. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. Both arrangements have credit risk essentially the same as that involved in extending loans to customers and are subject to the Company’s normal credit policies. Collateral (e.g., securities, receivables, inventory, equipment, etc.) is obtained based on management’s credit assessment of the customer. The Company’s unfunded loan commitments (unfunded loans and unused lines of credit) and standby letters of credit outstanding at December 31, 2015 were $1,131,842 and $37,063 , respectively, compared to $706,972 and $31,804 , respectively, at December 31, 2014 . Various claims and lawsuits are pending against the Company and Renasant Bank. In the opinion of management, after consultation with legal counsel, resolution of these matters is not expected to have a material effect on the consolidated financial statements. Market risk resulting from interest rate changes on particular off-balance sheet financial instruments may be offset by other on - or off-balance sheet transactions. Interest rate sensitivity is monitored by the Company for determining the net effect of potential changes in interest rates on the market value of both on- and off-balance sheet financial instruments.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit and Deferred Compensation Plans	Employee Benefit and Deferred Compensation Plans (In Thousands, Except Share Data) The Company sponsors a noncontributory defined benefit pension plan, under which participation and future benefit accruals ceased as of December 31, 1996. As a result of the acquisition of First M&F, the M&F Bank pension plan, under which accruals had ceased prior to the acquisition date, was merged into the Company’s existing pension plan during the fourth quarter of 2013. The Company’s funding policy is to contribute annually to the plan an amount at least equal to the minimum amount determined by consulting actuaries in accordance with the requirements of the Internal Revenue Code of 1986, as amended. No contributions were made to the pension plan in 2015 or 2014 . The Company does not anticipate that a contribution will be required in 2016 . In connection with the acquisition of Heritage in 2015, the Company assumed the defined benefit pension plan maintained by HeritageBank, under which accruals had ceased and which had been terminated by HeritageBank immediately prior to the acquisition date. Complete distribution of pension benefits under this plan is anticipated to occur once determinations as to the status of the plan’s termination have been received from the Pension Benefit Guarantee Corporation and the Internal Revenue Service. Each plan’s accumulated benefit obligation and respective projected benefit obligation are substantially the same since benefit accruals under each plan have ceased. The accumulated benefit obligation for the Renasant legacy plan was $27,856 and $28,087 at December 31, 2015 and 2014 , respectively. The accumulated benefit obligation for the assumed HeritageBank plan was $12,913 at December 31, 2015 . There is no additional minimum pension liability required to be recognized for either plan. The Company also provides retiree health care benefits for certain employees who were employed by the Company and enrolled in the Company’s health plan as of December 31, 2004. To receive benefits, an eligible employee must retire from service with the Company and its affiliates between age 55 and 65 and be credited with at least 15 years of service or with 70 points, determined as the sum of age and service at retirement. The Company periodically determines the portion of the premium to be paid by each eligible retiree and the portion to be paid by the Company. Coverage ceases when an employee attains age 65 and is eligible for Medicare. The Company also provides life insurance coverage for each retiree in the face amount of $5 until age 70 . Retirees can purchase additional insurance or continue coverage beyond age 70 at their sole expense. The Company has accounted for its obligation related to these retiree benefits in accordance with ASC 715, “Compensation – Retirement Benefits.” The assumed rate of increase in the per capita cost of covered benefits (i.e., health care cost trend rate) for the next year is 5.6% . Increasing or decreasing the assumed health care cost trend rates by one percentage point in each year would not materially increase or decrease the accumulated post-retirement benefit obligation or the service and interest cost components of net periodic post-retirement benefit costs as of December 31, 2015 , and for the year then ended. Information relating to the legacy Renasant defined benefit pension plan (“Pension Benefits - Renasant”), the assumed HeritageBank defined benefit pension plan (“Pension Benefits - HeritageBank”) and post-retirement health and life plan (“Other Benefits”) as of December 31, 2015 and 2014 is as follows: Pension Benefits Renasant Pension Benefits HeritageBank Other Benefits 2015 2014 2015 2014 2015 2014 Change in benefit obligation Benefit obligation at beginning of year $ 28,087 $ 27,364 $ — $ — $ 1,941 $ 2,082 Service cost — — — — 17 14 Interest cost 1,095 1,292 305 — 60 84 Plan participants’ contributions — — — — 82 77 Actuarial loss (gain) 605 2,601 (685 ) — (37 ) (118 ) Benefits paid (1,931 ) (3,170 ) (15 ) — (359 ) (198 ) Settlements — — (2,187 ) — — — Addition from business combination — — 15,495 — — — Benefit obligation at end of year $ 27,856 $ 28,087 $ 12,913 $ — $ 1,704 $ 1,941 Change in fair value of plan assets Fair value of plan assets at beginning of year $ 26,532 $ 27,989 $ — $ — Actual return on plan assets (167 ) 1,713 (21 ) — Contribution by employer — — — — Benefits paid (1,931 ) (3,170 ) (15 ) — Settlements (2,187 ) — Addition from business combination — — 14,681 — Fair value of plan assets at end of year $ 24,434 $ 26,532 $ 12,458 $ — Funded status at end of year $ (3,422 ) $ (1,555 ) $ (455 ) $ — $ (1,704 ) $ (1,941 ) Weighted-average assumptions as of December 31 Discount rate used to determine the benefit obligation 4.56 % 4.00 % 4.27 % N/A 3.63 % 3.22 % The discount rate assumptions at December 31, 2015 were determined using a yield curve approach. A yield curve was developed for a selection of high quality fixed-income investments whose cash flows approximate the timing and amount of expected cash flows from the benefit plans. The selected discount rate is the rate that produces the same present value of the benefit plan’s projected benefit payments. The components of net periodic benefit cost and other amounts recognized in other comprehensive income for the defined benefit pension and post-retirement health and life plans for the year ended December 31, 2015 , 2014 and 2013 are as follows: Pension Benefits Renasant Pension Benefits HeritageBank (1) Other Benefits 2015 2014 2013 2015 2015 2014 2013 Service cost $ — $ — $ — $ — $ 17 $ 14 $ 28 Interest cost 1,095 1,292 899 305 60 84 70 Expected return on plan assets (2,040 ) (2,160 ) (1,445 ) (216 ) — — — Prior service cost recognized — — — — — — — Recognized actuarial loss 331 207 427 — 101 89 195 Settlement/curtailment/termination losses — 453 — (65 ) — — — Net periodic benefit cost (614 ) (208 ) (119 ) 24 178 187 293 Net actuarial loss/(gain) arising during the period 2,812 3,047 (3,675 ) (448 ) (37 ) (118 ) 505 Net Settlement/curtailment/termination losses — (453 ) — 65 Amortization of net actuarial loss recognized in net periodic pension cost (331 ) (207 ) (427 ) — (101 ) (89 ) (195 ) Total recognized in other comprehensive income 2,481 2,387 (4,102 ) (383 ) (138 ) (207 ) 310 Total recognized in net periodic benefit cost and other comprehensive income $ 1,867 $ 2,179 $ (4,221 ) $ (359 ) $ 40 $ (20 ) $ 603 Weighted-average assumptions as of December 31 Discount rate used to determine net periodic pension cost 4.00 % 4.83 % 3.90 % 4.00 % 3.22 % 4.66 % 3.04 % Expected return on plan assets 8.00 % 8.00 % 8.00 % 3.00 % N/A N/A N/A (1) Net periodic benefit cost and other amounts recognized in other comprehensive income for the assumed HeritageBank defined benefit pension plan were recognized in the Company’s results of operations beginning on the date of acquisition; therefore, disclosure of amounts recognized in prior periods is not necessary. Future estimated benefit payments under the defined benefit pension plans and post-retirement health and life plan are as follows: Pension Benefits Renasant Pension Benefits HeritageBank Other Benefits 2016 $ 2,005 $ 12,913 $ 251 2017 2,002 — 249 2018 2,011 — 249 2019 2,013 — 212 2020 2,006 — 190 2021 - 2025 9,676 — 746 Amounts recognized in accumulated other comprehensive income, before tax, for the year ended December 31, 2015 are as follows: Pension Benefits Renasant Pension Benefits HeritageBank Other Benefits Prior service cost $ — $ — $ — Actuarial loss 11,915 (383 ) 550 Total $ 11,915 $ (383 ) $ 550 The estimated costs that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year are as follows: Pension Benefits Renasant Pension Benefits HeritageBank Other Benefits Prior service cost $ — $ — $ — Actuarial loss 400 — 68 Total $ 400 $ — $ 68 The investment objective for the legacy Renasant defined benefit pension plan is to achieve above average income and moderate long term growth, while the investment objective for the Heritage defined benefit pension plan is to preserve capital pending the distribution of pension benefits upon its dissolution. An investment committee appointed by management seeks to accomplish this objective by combining an equity income strategy (approximately 60% to 70% ), which generally invests in larger capitalization common stocks, and an intermediate fixed income strategy (approximately 30% to 40% ), which generally invests in U.S. Government securities and investment grade corporate bonds. In response to the current interest rate environment, the committee has begun allocating assets to the higher end of the target range for equity funds in order to lessen the impact of anticipated rising interest rates on the fixed income funds. It is the investment committee’s intent to give the investment managers flexibility within the overall guidelines with respect to investment decisions and their timing. However, significant modifications of any previously approved investments or anticipated use of derivatives to execute investment strategies must be approved by the committee. The plan’s expected long-term rate of return was estimated using market benchmarks for investment classes applied to the plan’s target asset allocation. The expected return on investment classes was computed using a valuation methodology which projected future returns based on current equity valuations rather than historical returns. The fair values of the Company’s defined benefit pension plan assets by category for both the legacy Renasant defined benefit pension plan and the assumed HeritageBank defined benefit pension plan at December 31, 2015 and 2014 follow below. The plan assets of the assumed HeritageBank defined benefit pension plan were fully invested in cash and cash equivalents at December 31, 2015 . Equity securities consist primarily of common stocks of both U.S. companies and international companies that are traded in active markets and are valued based on quoted market prices of identical assets (Level 1). The Company's investments in registered investment companies consist primarily of investments in funds that invest in investment grade fixed income securities. These investments are traded in active markets and are valued based on quoted market prices of identical assets (Level 1). Fixed income securities consist of U.S. Government securities, investment grade corporate bonds, and municipal obligations. The fair values of these instruments are based on quoted market prices of similar instruments or a discounted cash flow model (Level 2).

Employees may contribute pre-tax earnings, subject to a maximum established annually by the IRS. The Company matches employee deferrals, up to 4% of compensation. The Company also makes a nondiscretionary contribution for each eligible employee in an amount equal to 5% of plan compensation and 5% of plan compensation in excess of the Social Security wage base. Employees are automatically enrolled in the plan when employment commences. Company contributions are allocated to participants who are employed on the last day of each plan year and credited with 1000 hours of service during the year. The Company’s costs related to the 401(k) plan, excluding employee deferrals, in 2015 , 2014 and 2013 were $9,271 , $7,230 and $5,488 , respectively. In connection with the Heritage acquisition, the Company assumed the HeritageBank of the South 401(k) Plan maintained by HeritageBank, under which all accruals had ceased and which had been terminated by HeritageBank immediately prior to the acquisition date. Distribution of benefits under this plan made solely on account of its termination is anticipated to occur once a determination as to its qualified status in connection with its termination has been received from the Internal Revenue Service. There was no impact on the Company's consolidated financial statements as of and for the year ended December 31, 2015 associated with this plan. The Company adopted the “Performance Based Rewards” incentive compensation plan on January 1, 2001, under which annual cash bonuses are paid to eligible officers and employees, subject to the attainment of designated performance criteria. The Company designates minimum levels of performance for all applicable profit centers and rewards employees on performance over the minimum level. The expense associated with the plan for 2015 , 2014 and 2013 was $3,608 , $4,100 and $4,376 , respectively. The Company maintains three deferred compensation plans: a Deferred Stock Unit Plan and two conventional deferred compensation plans. Nonemployee directors may defer all or any portion of their fees and retainer to the Deferred Stock Unit Plan or the deferred compensation plan maintained for their benefit. Officers may defer base salary and bonus to the Deferred Stock Unit Plan or salary to the deferred compensation plan maintained for their benefit, subject to limits that are determined annually by the Company. Amounts credited to the Deferred Stock Unit Plan are invested in units representing shares of the Company’s common stock. Amounts credited to the conventional deferred compensation plans are invested at the discretion of each participant from among designated investment alternatives. Directors and officers who participated in these deferred compensation plans on or before December 31, 2006, may invest in a preferential interest rate investment that is derived from the Moody’s Average Corporate Bond Rate, adjusted monthly, and the beneficiaries of participants in the deferred compensation plans as of such date may receive a preretirement death benefit in excess of the amounts credited to plan accounts at the time of death. All of the Company’s deferred compensation plans are unfunded. It is anticipated that the two conventional deferred compensation plans will result in no additional cost to the Company because life insurance policies on the lives of the participants have been purchased in amounts estimated to be sufficient to pay plan benefits. The Company is both the owner and beneficiary of the life insurance policies. The expense recorded in 2015 , 2014 and 2013 for the Company’s deferred compensation plans, inclusive of deferrals, was $1,225 , $1,383 and $2,088 , respectively. In connection with the Heritage acquisition, the Company assumed the Heritage Financial Group Deferred Compensation and Excess/Matching Contribution Plan maintained by Heritage, under which all accruals had ceased and which had been terminated by Heritage immediately prior to the acquisition date. The distribution of accrued account balances was effected as soon as practicable following the acquisition date. There was no other impact on the Company’s consolidated financial statements as of and for the year ended December 31, 2015 associated with this plan. The Company assumed four supplemental executive retirement plans (SERPs) in connection with the acquisition of Capital in 2007. The SERPs were established by Capital to provide supplemental retirement benefits. The plans provide four officers of the Company specified annual benefits based upon a projected retirement date. These benefits are payable for a 15 -year period after retirement. The supplemental executive retirement liabilities totaled $3,364 and $3,094 at December 31, 2015 and 2014 , respectively. The plans are not qualified under Section 401 of the Internal Revenue Code. In connection with the Heritage acquisition, the Company assumed the Heritage Financial Group Employee Stock Ownership Plan (“the Heritage ESOP”) maintained by Heritage, under which all accruals had ceased and which had been terminated by Heritage immediately prior to the acquisition date. As of the date of acquisition, the Heritage ESOP had a loan outstanding, inclusive of accrued interest, of $2,839 due to Heritage which was assumed by the Company. Unallocated shares of Company common stock pledged as collateral for the loan were sold in order to repay the loan in full, including any accrued interest. Any unallocated shares of Company common stock that remained after the repayment of the loan were allocated to the accounts of the participants. Distribution of benefits under the Heritage ESOP made solely on account of its termination is anticipated to occur once a determination as to its qualified status in connection with its termination has been received from the Internal Revenue Service. Other than the transactions recorded in connection with the loan repayment, there was no impact on the Company’s consolidated financial statements as of and for the year ended December 31, 2015 associated with this plan. In March 2011, the Company adopted a long-term equity incentive plan, which provides for the grant of stock options and the award of restricted stock. The plan replaced the long-term incentive plan adopted in 2001, which expired in October 2011. The Company issues shares of treasury stock to satisfy stock options exercised or restricted stock granted under the plan. Options granted under the plan allow participants to acquire shares of the Company’s common stock at a fixed exercise price and expire ten years after the grant date. Options vest and become exercisable in installments over a three -year period measured from the grant date. Options that have not vested are forfeited and cancelled upon the termination of a participant’s employment. The Company recorded compensation expense of $73 , $262 and $469 for the years ended December 31, 2015 , 2014 and 2013 , respectively, for options granted under the plan. There were no stock options granted during the years ended December 31, 2015 or December 31, 2014 . The fair value of the options granted during the year ended December 31, 2013 was estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions: 2013 Grant Dividend yield 3.55 % Expected volatility 37 % Risk-free interest rate 0.76 % Expected lives 6 years Weighted average fair value $ 4.47 The following table summarizes information about options issued under the long-term equity incentive plan as of and for the three years ended December 31, 2015 : Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1, 2013 1,279,248 $ 18.79 Assumed in acquisition 11,557 21.16 Granted 52,500 19.14 Exercised (272,957 ) 19.22 Forfeited (10,000 ) 27.20 Outstanding at December 31, 2013 1,060,348 $ 18.64 4.89 $ 13,592 Exercisable at December 31, 2013 843,237 $ 19.21 4.08 $ 10,331 Granted — — Exercised (227,499 ) 18.39 Forfeited (1,899 ) 20.77 Outstanding at December 31, 2014 830,950 $ 18.70 4.48 $ 8,680 Exercisable at December 31, 2014 745,949 $ 18.95 4.15 $ 7,628 Granted — — Exercised (201,371 ) 20.82 Forfeited (8,133 ) 29.45 Outstanding at December 31, 2015 621,446 $ 17.88 3.91 $ 10,274 Exercisable at December 31, 2015 606,027 $ 17.85 3.83 $ 10,038 The total intrinsic value of options exercised during the years ended December 31, 2015 , 2014 and 2013 was $2,445 , $2,519 and $1,655 , respectively. The total grant date fair value of options vested during the same periods was $235 , $458 , and $535 , respectively. The Company awards performance-based restricted stock to executives and other officers and time-based restricted stock to directors, executives, and other officers and employees under the long-term equity incentive plan. The performance-based restricted stock vests upon completion of a one -year service period and the attainment of certain performance goals. Performance-based restricted stock is issued at the target level; the number of shares ultimately awarded is determined at the end of each year and may be increased or decreased depending upon the Company meeting or exceeding financial performance measures defined by the Board of Directors. Time-based restricted stock vests at the end of the service period defined in the respective grant. The fair value of each restricted stock grant is the closing price of the Company’s common stock on the day immediately preceding the grant date. The Company recorded compensation expense of $3,884 , $3,647 and $2,330 for the years ended December 31, 2015 , 2014 and 2013 , respectively, for restricted stock awarded under the plan. The following table summarizes the changes in restricted stock as of and for the year ended December 31, 2015 : Performance- Based Restricted Stock Weighted Average Grant-Date Fair Value Time- Based Restricted Stock Weighted Average Grant-Date Fair Value Nonvested at beginning of year — $ — 38,336 $ 27.26 Granted 97,666 28.93 103,588 (2) 31.56 Vested (94,916 ) (1) 28.93 (32,236 ) 29.54 Cancelled (2,750 ) 28.93 (4,250 ) 25.54 Nonvested at end of year — $ — 105,438 $ 31.04 (1) In January 2015 , the Company awarded 81,750 shares of performance-based restricted stock based on the target level of performance goals of which 2,750 were cancelled prior to the attainment of performance goals. The Company exceeded the financial performance measures for the award; therefore, an additional 15,916 shares were issued for a total award of 94,916 shares. (2) Includes shares of time-based restricted stock granted as an inducement award to certain employees in connection with the Heritage acquisition. This award was made outside the Company's long-term equity incentive plan. Unrecognized stock-based compensation expense related to restricted stock totaled $1,463 at December 31, 2015 . At such date, the weighted average period over which this unrecognized expense is expected to be recognized was approximately 1.7 years. There was no unrecognized stock-based compensation expense related to stock options at December 31, 2015 . At December 31, 2015 , an aggregate of 1,030,578 shares of Company common stock were reserved for issuance under the Company’s employee benefit plans.

Restrictions on Cash, Bank Dividends, Loans or Advances	Restrictions on Cash, Bank Dividends, Loans or Advances (In Thousands) Renasant Bank is required to maintain minimum average balances with the Federal Reserve. At December 31, 2015 and 2014 , Renasant Bank’s reserve requirements with the Federal Reserve were $55,237 and $52,295 , respectively, with which it was in full compliance. The Company’s ability to pay dividends to its shareholders is substantially dependent on the ability of Renasant Bank to transfer funds to the Company in the form of dividends, loans and advances. Under Mississippi law, a Mississippi bank may not pay dividends unless its earned surplus is in excess of three times capital stock. A Mississippi bank with earned surplus in excess of three times capital stock may pay a dividend, subject to the approval of the Mississippi Department of Banking and Consumer Finance. Accordingly, the approval of this supervisory authority is required prior to Renasant Bank paying dividends to the Company. Federal Reserve regulations also limit the amount Renasant Bank may loan to the Company unless such loans are collateralized by specific obligations. At December 31, 2015 , the maximum amount available for transfer from Renasant Bank to the Company in the form of loans was $70,159 . As of December 31, 2015 , no loans from the Bank to the Company were outstanding. In connection with the acquisition of First M&F, the Company assumed an interest rate swap agreement designed to convert floating rate interest payments on subordinated debentures into fixed rate payments. The Company had pledged interest bearing bank balances as collateral to the interest rate swap counterparty in the amounts of $1,970 at December 31, 2015 .

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters (In Thousands) Renasant Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on Renasant Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Renasant Bank must meet specific capital guidelines that involve quantitative measures of Renasant Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Renasant Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The Federal Reserve, the FDIC and the Office of the Comptroller of the Currency have issued guidelines governing the levels of capital that banks must maintain. Those guidelines specify capital tiers, which include the following classifications: Capital Tiers Tier 1 Capital to Average Assets (Leverage) Common Equity Tier 1 to Risk - Weighted Assets Tier 1 Capital to Risk – Weighted Assets Total Capital to Risk – Weighted Assets Well capitalized 5% or above 6.5% or above 8% or above 10% or above Adequately capitalized 4% or above 4.5% or above 6% or above 8% or above Undercapitalized Less than 4% Less than 4.5% Less than 6% Less than 8% Significantly undercapitalized Less than 3% Less than 3% Less than 4% Less than 6% Critically undercapitalized Tangible Equity / Total Assets less than 2% The following table provides the capital and risk-based capital and leverage ratios for the Company and for Renasant Bank as of December 31: 2015 2014 Amount Ratio Amount Ratio Renasant Corporation Tier 1 Capital to Average Assets (Leverage) $ 681,731 9.16 % $ 521,124 9.53 % Common Equity Tier 1 Capital to Risk-Weighted Assets 591,356 9.99 % — — % Tier 1 Capital to Risk-Weighted Assets 681,731 11.51 % 521,124 12.45 % Total Capital to Risk-Weighted Assets 729,321 12.32 % 566,514 13.54 % Renasant Bank Tier 1 Capital to Average Assets (Leverage) $ 654,830 8.82 % $ 503,316 9.23 % Common Equity Tier 1 Capital to Risk-Weighted Assets 654,830 11.09 % — — % Tier 1 Capital to Risk-Weighted Assets 654,830 11.09 % 503,316 12.06 % Total Capital to Risk-Weighted Assets 701,591 11.89 % 548,124 13.14 % In July 2013, the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency approved the implementation of the Basel III regulatory capital reforms and issued rules effecting certain changes required by the Dodd-Frank Act (the “Basel III Rules”) that call for broad and comprehensive revision of regulatory capital standards for U.S. banking organizations. The Basel III Rules implemented a new common equity Tier 1 minimum capital requirement (“CET1”), a higher minimum Tier 1 capital requirement and other items affecting the calculation of the numerator of a banking organization’s risk-based capital ratios. Additionally, the Basel III Rules apply limits to a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a specified amount of CET1 capital in addition to the amount necessary to meet its minimum risk-based capital requirements. The new CET1 capital ratio includes common equity as defined under GAAP and does not include any other type of non-common equity under GAAP. Banks must now maintain CET1 capital of 4.5% of average assets, Tier 1 capital of 6% of average assets and total capital of 8% of risk-weighted assets to be categorized as adequately capitalized. Further, the Basel III Rules changed the agencies’ general risk-based capital requirements for determining risk-weighted assets, which affect the calculation of the denominator of a banking organization’s risk-based capital ratios. The Basel III Rules have revised the agencies’ rules for calculating risk-weighted assets to enhance risk sensitivity and to incorporate certain international capital standards of the Basel Committee on Banking Supervision set forth in the standardized approach of the “International Convergence of Capital Measurement and Capital Standards: A Revised Framework”. The calculation of risk-weighted assets in the denominator of the Basel III capital ratios has been adjusted to reflect the higher risk nature of certain types of loans. Specifically, as applicable to the Company and Renasant Bank: — Residential mortgages: Replaces the current 50% risk weight for performing residential first-lien mortgages and a 100% risk-weight for all other mortgages with a risk weight of between 35% and 200% determined by the mortgage’s loan-to-value ratio and whether the mortgage falls into one of two categories based on eight criteria that include the term, use of negative amortization and balloon payments, certain rate increases and documented and verified borrower income. — Commercial mortgages: Replaces the current 100% risk weight with a 150% risk weight for certain high volatility commercial real estate acquisition, development and construction loans. — Nonperforming loans: Replaces the current 100% risk weight with a 150% risk weight for loans, other than residential mortgages, that are 90 days past due or on nonaccrual status. The Final Rules also introduce a new capital conservation buffer designed to absorb losses during periods of economic stress. The capital conservation buffer is composed entirely of CET1, on top of these minimum risk-weighted asset ratios. In addition, the Final Rules provide for a countercyclical capital buffer applicable only to certain covered institutions. It is not expected that the countercyclical capital buffer will be applicable to Renasant Corporation or Renasant Bank. Banking institutions with a ratio of CET1 to risk-weighted assets above the minimum but below the capital conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and be phased in over a 4-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). Generally, the new Basel III Rules became effective on January 1, 2015, although parts of the Basel III Rules will be phased in through 2019.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting (In Thousands) The operations of the Company’s reportable segments are described as follows: • The Community Banks segment delivers a complete range of banking and financial services to individuals and small to medium-sized businesses including checking and savings accounts, business and personal loans, equipment leasing, as well as safe deposit and night depository facilities. • The Insurance segment includes a full service insurance agency offering all lines of commercial and personal insurance through major carriers. • The Wealth Management segment offers a broad range of fiduciary services which includes the administration and management of trust accounts including personal and corporate benefit accounts, self-directed IRA’s, and custodial accounts. In addition, the Wealth Management segment offers annuities, mutual funds and other investment services through a third party broker-dealer. In order to give the Company’s divisional management a more precise indication of the income and expenses they can control, the results of operations for the Community Banks, the Insurance and the Wealth Management segments reflect the direct revenues and expenses of each respective segment. Indirect revenues and expenses, including but not limited to income from the Company’s investment portfolio, as well as certain costs associated with data processing and back office functions, primarily support the operations of the community banks and, therefore, are included in the results of the Community Banks segment. Included in “Other” are the operations of the holding company and other eliminations which are necessary for purposes of reconciling to the consolidated amounts.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements (In Thousands) Recurring Fair Value Measurements The Company carries certain assets and liabilities at fair value on a recurring basis in accordance with applicable standards. The Company’s recurring fair value measurements are based on the requirement to carry such assets and liabilities at fair value or the Company’s election to carry certain eligible assets and liabilities at fair value. Assets and liabilities that are required to be carried at fair value include securities available for sale and derivative instruments. The Company has elected to carry mortgage loans held for sale at fair value on a recurring basis as permitted under the guidance in ASC 825. The following methods and assumptions are used by the Company to estimate the fair values of the Company’s financial assets and liabilities that are measured on a recurring basis: Securities available for sale : Securities available for sale consist primarily of debt securities, such as obligations of U.S. Government agencies and corporations, mortgage-backed securities, trust preferred securities, and other debt and equity securities. Where quoted market prices in active markets are available, securities are classified within Level 1 of the fair value hierarchy. If quoted prices from active markets are not available, fair values are based on quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active, or model-based valuation techniques where all significant assumptions are observable in the market. Such instruments are classified within Level 2 of the fair value hierarchy. When assumptions used in model-based valuation techniques are not observable in the market, the assumptions used by management reflect estimates of assumptions used by other market participants in determining fair value. When there is limited transparency around the inputs to the valuation, the instruments are classified within Level 3 of the fair value hierarchy. Derivative instruments : The Company uses derivatives to manage various financial risks. Most of the Company’s derivative contracts are actively traded in over-the-counter markets and are valued using discounted cash flow models which incorporate observable market based inputs including current market interest rates, credit spreads, and other factors. Such instruments are categorized within Level 2 of the fair value hierarchy and include interest rate swaps and other interest rate contracts including interest rate caps and/or floors. The Company’s interest rate lock commitments are valued using current market prices for mortgage-backed securities with similar characteristics, adjusted for certain factors including servicing and risk. The value of the Company’s forward commitments is based on current prices for securities backed by similar types of loans. Because these assumptions are observable in active markets, the Company’s interest rate lock commitments and forward commitments are categorized within Level 2 of the fair value hierarchy. Mortgage loans held for sale : Mortgage loans held for sale are primarily agency loans which trade in active secondary markets. The fair value of these instruments is derived from current market pricing for similar loans, adjusted for differences in loan characteristics, including servicing and risk. Because the valuation is based on external pricing of similar instruments, mortgage loans held for sale are classified within Level 2 of the fair value hierarchy. The following table presents assets and liabilities that are measured at fair value on a recurring basis as of the dates presented: Level 1 Level 2 Level 3 Totals December 31, 2015 Financial assets: Securities available for sale: Obligations of other U.S. Government agencies and corporations $ — $ 6,200 $ — $ 6,200 Residential mortgage-backed securities: Government agency mortgage backed securities — 364,540 — 364,540 Government agency collateralized mortgage obligations — 168,060 — 168,060 Commercial mortgage-backed securities: Government agency mortgage backed securities — 59,759 — 59,759 Government agency collateralized mortgage obligations — 5,104 — 5,104 Trust preferred securities — — 19,469 19,469 Other debt securities — 19,333 — 19,333 Other equity securities — 4,340 — 4,340 Total securities available for sale — 627,336 19,469 646,805 Derivative instruments: Interest rate swap — — — — Interest rate contracts — 2,544 — 2,544 Interest rate lock commitments — 4,508 — 4,508 Forward commitments — 446 — 446 Total derivative instruments — 7,498 — 7,498 Mortgage loans held for sale — 225,254 — 225,254 Total financial assets $ — $ 860,088 $ 19,469 $ 879,557 Financial liabilities: Derivative instruments: Interest rate swap $ — $ 4,266 $ — $ 4,266 Interest rate contracts — 2,544 — 2,544 Interest rate lock commitments — — — — Forward commitments — 509 — 509 Total derivative instruments — 7,319 — 7,319 Total financial liabilities $ — $ 7,319 $ — $ 7,319 Level 1 Level 2 Level 3 Totals December 31, 2014 Financial assets: Securities available for sale: Obligations of other U.S. Government agencies and corporations $ — $ 6,147 $ — $ 6,147 Residential mortgage-backed securities: Government agency mortgage backed securities — 296,359 — 296,359 Government agency collateralized mortgage obligations — 157,436 — 157,436 Commercial mortgage-backed securities: Government agency mortgage backed securities — 47,185 — 47,185 Government agency collateralized mortgage obligations — 5,172 — 5,172 Trust preferred securities — — 19,756 19,756 Other debt securities — 17,930 — 17,930 Other equity securities — 3,599 — 3,599 Total securities available for sale — 533,828 19,756 553,584 Derivative instruments: Interest rate swap — — — — Interest rate contracts — 2,142 — 2,142 Interest rate lock commitments — 1,584 — 1,584 Forward commitments — 5 — 5 Total derivative instruments — 3,731 — 3,731 Mortgage loans held for sale — 25,628 — 25,628 Total financial assets $ — $ 563,187 $ 19,756 $ 582,943 Financial liabilities: Derivative instruments: Interest rate swap $ — $ 3,847 $ — $ 3,847 Interest rate contracts — 2,143 — 2,143 Interest rate lock commitments — — — — Forward commitments — 303 — 303 Total derivative instruments — 6,293 — 6,293 Total financial liabilities $ — $ 6,293 $ — $ 6,293 The Company reviews fair value hierarchy classifications on a quarterly basis. Changes in the Company’s ability to observe inputs to the valuation may cause reclassification of certain assets or liabilities within the fair value hierarchy. The following tables provide a reconciliation for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs, or Level 3 inputs: Securities available for sale Trust preferred securities Total Balance at January 1, 2014 $ 17,671 $ 17,671 Realized (gains) losses included in net income, net of premium amortization 33 33 Unrealized gains included in other comprehensive income 3,216 3,216 Reclassification adjustment — — Sales — — Issues — — Settlements (1,164 ) (1,164 ) Transfers into Level 3 — — Transfers out of Level 3 — — Balance at December 31, 2014 $ 19,756 $ 19,756 Realized (gains) losses included in net income, net of premium amortization (62 ) (62 ) Unrealized gains included in other comprehensive income 1,439 1,439 Sales (1,117 ) (1,117 ) Issues — — Settlements (547 ) (547 ) Transfers into Level 3 — — Transfers out of Level 3 — — Balance at December 31, 2015 $ 19,469 $ 19,469 For 2015 and 2014 , there were no gains or losses included in earnings that were attributable to the change in unrealized gains or losses related to assets or liabilities held at the end of each respective period that were measured on a recurring basis using significant unobservable inputs. The following table presents information as of December 31, 2015 about significant unobservable inputs (Level 3) used in the valuation of assets and liabilities measured at fair value on a recurring basis: Financial instrument Fair Value Valuation Technique Significant Unobservable Inputs Range of Inputs Trust preferred securities $ 19,469 Discounted cash flows Default rate 0-100% Nonrecurring Fair Value Measurements Certain assets may be recorded at fair value on a nonrecurring basis. These nonrecurring fair value adjustments typically are a result of the application of the lower of cost or market accounting or a write-down occurring during the period. The following table provides the fair value measurement for assets measured at fair value on a nonrecurring basis that were still held on the Consolidated Balance Sheets as of the dates presented and the level within the fair value hierarchy each is classified: Level 1 Level 2 Level 3 Totals December 31, 2015 Impaired loans $ — $ — $ 6,508 $ 6,508 OREO — — 12,839 12,839 Total $ — $ — $ 19,347 $ 19,347 Level 1 Level 2 Level 3 Totals December 31, 2014 Impaired loans $ — $ — $ 12,360 $ 12,360 OREO — — 4,460 4,460 Total $ — $ — $ 16,820 $ 16,820 The following methods and assumptions are used by the Company to estimate the fair values of the Company’s assets measured on a nonrecurring basis: Impaired loans : Loans considered impaired are reserved for at the time the loan is identified as impaired taking into account the fair value of the collateral less estimated selling costs. Collateral may be real estate and/or business assets including but not limited to equipment, inventory and accounts receivable. The fair value of real estate is determined based on appraisals by qualified licensed appraisers. The fair value of the business assets is generally based on amounts reported on the business’s financial statements. Appraised and reported values may be adjusted based on changes in market conditions from the time of valuation and management’s knowledge of the client and the client’s business. Since not all valuation inputs are observable, these nonrecurring fair value determinations are classified as Level 3. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors previously identified. Impaired loans covered under loss-share agreements were recorded at their fair value upon the acquisition date, and no fair value adjustments were necessary for loans still carried on the balance sheet at December 31, 2015 or 2014 , respectively. Impaired loans not covered under loss-share agreements that were measured or re-measured at fair value had a carrying value of $7,191 and $13,349 at December 31, 2015 and December 31, 2014 , respectively, and a specific reserve for these loans of $683 and $989 was included in the allowance for loan losses for the same periods ended. Other real estate owned : OREO is comprised of commercial and residential real estate obtained in partial or total satisfaction of loan obligations. OREO covered under loss-share agreements is recorded at its fair value at its acquisition date. OREO not covered under loss-share agreements acquired in settlement of indebtedness is recorded at the fair value of the real estate less estimated costs to sell. Subsequently, it may be necessary to record nonrecurring fair value adjustments for declines in fair value. Fair value, when recorded, is determined based on appraisals by qualified licensed appraisers and adjusted for management’s estimates of costs to sell. Accordingly, values for OREO are classified as Level 3. The following table presents OREO measured at fair value on a nonrecurring basis that was still held in the Consolidated Balance Sheets as of the dates presented: December 31, 2015 December 31, 2014 OREO covered under loss-share agreements: Carrying amount prior to remeasurement $ — $ 3,162 Impairment recognized in results of operations — (185 ) Increase in FDIC loss-share indemnification asset — (742 ) Receivable from other guarantor — (422 ) Fair value $ — $ 1,813 OREO not covered under loss-share agreements: Carrying amount prior to remeasurement $ 14,726 $ 3,513 Impairment recognized in results of operations (1,887 ) (866 ) Fair value $ 12,839 $ 2,647 The following table presents information as of December 31, 2015 about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis: Financial instrument Fair Value Valuation Technique Significant Unobservable Inputs Range of Inputs Impaired loans $ 6,508 Appraised value of collateral less estimated costs to sell Estimated costs to sell 4-10% OREO $ 12,839 Appraised value of property less estimated costs to sell Estimated costs to sell 4-10% Fair Value Option The Company elected to measure all mortgage loans originated for sale on or after July 1, 2012 at fair value under the fair value option as permitted under ASC 825. Electing to measure these assets at fair value reduces certain timing differences and better matches the changes in fair value of the loans with changes in the fair value of derivative instruments used to economically hedge them. Net losses of $1,099 resulting from fair value changes of these mortgage loans were recorded in income during 2015 . The amount does not reflect changes in fair values of related derivative instruments used to hedge exposure to market-related risks associated with these mortgage loans. The change in fair value of both mortgage loans held for sale and the related derivative instruments are recorded in “Mortgage banking income” in the Consolidated Statements of Income. The Company’s valuation of mortgage loans held for sale incorporates an assumption for credit risk; however, given the short-term period that the Company holds these loans, valuation adjustments attributable to instrument-specific credit risk is nominal. Interest income on mortgage loans held for sale measured at fair value is accrued as it is earned based on contractual rates and is reflected in loan interest income on the Consolidated Statements of Income. The following table summarizes the differences between the fair value and the principal balance for mortgage loans held for sale measured at fair value as of December 31, 2015 : Aggregate Fair Value Aggregate Unpaid Principal Balance Difference Mortgage loans held for sale measured at fair value $ 225,254 $ 219,352 $ 5,902 Past due loans of 90 days or more — — — Nonaccrual loans — — — Fair Value of Financial Instruments The carrying amounts and estimated fair values of the Company’s financial instruments, including those assets and liabilities that are not measured and reported at fair value on a recurring basis or nonrecurring basis, were as follows as of the dates presented: Fair Value Carrying Value Level 1 Level 2 Level 3 Total December 31, 2015 Financial assets Cash and cash equivalents $ 211,571 $ 211,571 $ — $ — $ 211,571 Securities held to maturity 458,400 — 473,753 — 473,753 Securities available for sale 646,805 — 627,336 19,469 646,805 Mortgage loans held for sale 225,254 — 225,254 — 225,254 Loans covered under loss-share agreements 93,142 — — 92,528 92,528 Loans not covered under loss-share agreements, net 5,277,883 — — 5,208,630 5,208,630 FDIC loss-share indemnification asset 7,149 — — 7,149 7,149 Mortgage servicing rights 29,642 — — 33,283 33,283 Derivative instruments 7,498 — 7,498 — 7,498 Financial liabilities Deposits $ 6,218,602 $ 4,723,312 $ 1,502,202 $ — $ 6,225,514 Short-term borrowings 422,279 422,279 — — 422,279 Other long-term borrowings 192 192 — — 192 Federal Home Loan Bank advances 52,930 — 56,101 — 56,101 Junior subordinated debentures 95,095 — 78,095 — 78,095 Derivative instruments 7,319 — 7,319 — 7,319 Fair Value Carrying Value Level 1 Level 2 Level 3 Total December 31, 2014 Financial assets Cash and cash equivalents $ 161,583 $ 161,583 $ — $ — $ 161,583 Securities held to maturity 430,163 — 442,488 — 442,488 Securities available for sale 553,584 — 533,828 19,756 553,584 Mortgage loans held for sale 25,628 — 25,628 — 25,628 Loans covered under loss-share agreements 143,041 — — 143,487 143,487 Loans not covered under loss-share agreements, net 3,844,833 — — 3,751,727 3,751,727 Mortgage servicing rights 11,662 — — 12,378 12,378 FDIC loss-share indemnification asset 12,516 — — 12,516 12,516 Derivative instruments 3,731 — 3,731 — 3,731 Financial liabilities Deposits $ 4,838,418 $ 3,532,266 $ 1,309,421 $ — $ 4,841,687 Short-term borrowings 32,403 32,403 — — 32,403 Other long-term borrowings 237 237 — — 237 Federal Home Loan Bank advances 61,611 — 92,532 — 92,532 Junior subordinated debentures 94,574 — 80,971 — 80,971 Derivative instruments 6,293 — 6,293 — 6,293 The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value. The methodologies for estimating the fair value of financial assets and liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed previously. Cash and cash equivalents : Cash and cash equivalents consist of cash and due from banks and interest-bearing balances with banks. The carrying amount reported in the Consolidated Balance Sheets for cash and cash equivalents approximates fair value based on the short-term nature of these assets. Securities held to maturity : Securities held to maturity consist of debt securities such as obligations of U.S. Government agencies, states, and other political subdivisions. Where quoted market prices in active markets are available, securities are classified within Level 1 of the fair value hierarchy. If quoted prices from active markets are not available, fair values are based on quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active, or model-based valuation techniques where all significant assumptions are observable in the market. Such instruments are classified within Level 2 of the fair value hierarchy. When assumptions used in model-based valuation techniques are not observable in the market, the assumptions used by management reflect estimates of assumptions used by other market participants in determining fair value. When there is limited transparency around the inputs to the valuation, the instruments are classified within Level 3 of the fair value hierarchy. Loans covered under loss-share agreements : The fair value of loans covered under loss-share agreements is based on the net present value of future cash proceeds expected to be received using discount rates that are derived from current market rates and reflect the level of interest risk in the covered loans. Loans not covered under loss-share agreements : For variable-rate loans not covered under loss-share agreements that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values of fixed-rate loans not covered under loss-share agreements, including mortgages, commercial, agricultural and consumer loans, are estimated using a discounted cash flow analysis based on interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Mortgage servicing rights : The Company retains the right to service certain mortgage loans that it sells to secondary market investors. These servicing rights are carried at the lower of amortized cost or fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, market discount rates, prepayment speeds, servicing costs, and other factors. Because these factors are not all observable and include management’s assumptions, mortgage servicing rights are classified within Level 3 of the fair value hierarchy. Mortgage servicing rights were carried at amortized cost at December 31, 2015 and 2014 , respectively, and no impairment charges were recognized in earnings during 2015 or 2014 . FDIC loss-share indemnification asset : The fair value of the FDIC loss-share indemnification asset is based on the net present value of future cash flows expected to be received from the FDIC under the provisions of the loss-share agreements using a discount rate that is based on current market rates for the underlying covered loans. Current market rates are used in light of the uncertainty of the timing and receipt of the loss-share reimbursement from the FDIC. Deposits : The fair values disclosed for demand deposits, both interest-bearing and noninterest-bearing, are, by definition, equal to the amount payable on demand at the reporting date. Such deposits are classified within Level 1 of the fair value hierarchy. The fair values of certificates of deposit and individual retirement accounts are estimated using a discounted cash flow based on currently effective interest rates for similar types of deposits. These deposits are classified within Level 2 of the fair value hierarchy. Short-term borrowings : Short-term borrowings consist of securities sold under agreements to repurchase and overnight borrowings. The fair value of these borrowings approximates the carrying value of the amounts reported in the Consolidated Balance Sheets for each respective account given the short-term nature of the liabilities. Federal Home Loan Bank advances : The fair value for FHLB advances is determined by discounting the expected future cash outflows using current market rates for similar borrowings, or Level 2 inputs. Junior subordinated debentures : The fair value for the Company’s junior subordinated debentures is determined using quoted market prices for similar instruments traded in active markets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments (In Thousands) The Company utilizes derivative financial instruments, including interest rate contracts such as swaps, caps and/or floors, as part of its ongoing efforts to mitigate its interest rate risk exposure and to facilitate the needs of its customers. The Company enters into derivative instruments that are not designated as hedging instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with these customer contracts, the Company enters into an offsetting derivative contract position. The Company manages its credit risk, or potential risk of default by its commercial customers, through credit limit approval and monitoring procedures. At December 31, 2015 , the Company had notional amounts of $68,409 on interest rate contracts with corporate customers and $68,409 in offsetting interest rate contracts with other financial institutions to mitigate the Company’s rate exposure on its corporate customers’ contracts. On June 5, 2014, the Company entered into two forward interest rate swap contracts on floating rate liabilities at the Bank level with notional amounts of $15,000 each. The interest rate swap contracts are accounted for as cash flow hedges with the objective of protecting against any interest rate volatility on future FHLB borrowings for a four -year and five -year period beginning June 1, 2018 and December 3, 2018 and ending June 2022 and June 2023, respectively. Under these contracts, Renasant Bank will pay a fixed interest rate of interest, and will receive a variable interest rate based on the three-month LIBOR plus a pre-determined spread, with quarterly net settlements. In March and April 2012, the Company entered into two interest rate swap agreements effective March 30, 2014 and March 17, 2014, respectively. Under these swap agreements, the Company receives a variable rate of interest based on the three-month LIBOR plus a pre-determined spread and pays a fixed rate of interest. The agreements, which both terminate in March 2022, are accounted for as cash flow hedges to reduce the variability in cash flows resulting from changes in interest rates on $32,000 of the Company’s junior subordinated debentures. In connection with its acquisition of First M&F, the Company assumed an interest rate swap designed to convert floating rate interest payments into fixed rate payments. Based on the terms of the agreement, which terminates in March 2018, the Company will receive a variable rate of interest based on the three-month LIBOR plus a pre-determined spread and pay a fixed rate of interest. The interest rate swap is accounted for as a cash flow hedge to reduce the variability in cash flows resulting from changes in interest rates on $30,000 of the junior subordinated debentures assumed in the acquisition of First M&F. In May 2010, the Company terminated two interest rate swaps, each designated as a cash flow hedge, designed to convert the variable interest rate on an aggregate of $75,000 of loans to a fixed rate. As of the termination date, there were $1,679 of deferred gains related to the swaps, which were amortized into interest income over the designated hedging periods which ended in August 2012 and August 2013. Deferred gains related to the swaps of $203 were amortized into net interest income for the year ended December 31, 2013 . No deferred gains related to the swaps were amortized into net interest income for the years ended December 31, 2015 and 2014 . The Company enters into interest rate lock commitments with its customers to mitigate the interest rate risk associated with the commitments to fund fixed-rate residential mortgage loans. The notional amount of commitments to fund fixed-rate mortgage loans was $251,676 and $62,288 at December 31, 2015 and 2014 , respectively. The Company also enters into forward commitments to sell residential mortgage loans to secondary market investors. The notional amount of commitments to sell residential mortgage loans to secondary market investors was $293,500 and $52,000 at December 31, 2015 and 2014 , respectively. The following table provides details on the Company’s derivative financial instruments as of the dates presented: Fair Value Balance Sheet December 31, Location 2015 2014 Derivative assets: Not designated as hedging instruments: Interest rate contracts Other Assets $ 2,544 $ 2,142 Interest rate lock commitments Other Assets 4,508 1,584 Forward commitments Other Assets 446 5 Totals $ 7,498 $ 3,731 Derivative liabilities: Designated as hedging instruments: Interest rate swap Other Liabilities $ 4,266 $ 3,847 Totals $ 4,266 $ 3,847 Not designated as hedging instruments: Interest rate contracts Other Liabilities $ 2,544 $ 2,143 Forward commitments Other Liabilities 509 303 Totals $ 3,053 $ 2,446 Gains (losses) included in the Consolidated Statements of Income related to the Company’s derivative financial instruments were as follows: Year Ended December 31, 2015 2014 2013 Derivatives designated as cash flow hedging instruments: Interest rate swap: Included in interest income on loans $ — $ — $ 203 Total $ — $ — $ 203 Derivatives not designated as hedging instruments: Interest rate contracts: Included in interest income on loans $ 2,200 $ 2,961 $ 3,193 Included in other noninterest expense — — 69 Interest rate lock commitments: Included in mortgage banking income (530 ) 1,171 (1,159 ) Forward commitments Included in mortgage banking income (1,917 ) (609 ) 509 Total $ (247 ) $ 3,523 $ 2,612 For the Company’s derivatives designated as cash flow hedges, changes in fair value of the cash flow hedges are, to the extent that the hedging relationship is effective, recorded as other comprehensive income and are subsequently recognized in earnings at the same time that the hedged item is recognized in earnings. The ineffective portions of the changes in fair value of the hedging instruments are immediately recognized in earnings. The assessment of the effectiveness of the hedging relationship is evaluated under the hypothetical derivative method. The impact of the ineffective portion for the year ended December 31, 2013 on earnings is shown in the table above. There were no ineffective portions for the years ended December 31, 2015 and 2014 . The impact on other comprehensive income for the years ended December 31, 2015 , 2014 , and 2013 , can be seen at Note V, “Other Comprehensive Income.” Offsetting Certain financial instruments, including derivatives, may be eligible for offset in the consolidated balance sheet when the “right of setoff” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements; however, the Company has not elected to offset such financial instruments in the consolidated balance sheets. The following table presents the Company’s gross derivative positions as recognized in the consolidated balance sheets as well as the net derivative positions, including collateral pledged to the extent the application of such collateral did not reduce the net derivative liability position below zero, had the Company elected to offset those instruments subject to an enforceable master netting agreement: Offsetting Derivative Assets Offsetting Derivative Liabilities December 31, December 31, December 31, December 31, Gross amounts recognized $ 446 $ 5 $ 6,454 $ 5,182 Gross amounts offset in the consolidated balance sheets — — — — Net amounts presented in the consolidated balance sheets 446 5 6,454 5,182 Gross amounts not offset in the consolidated balance sheets Financial instruments 282 5 282 5 Financial collateral pledged — — 6,020 4,879 Net amounts $ 164 $ — $ 152 $ 298

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations : Renasant Corporation (referred to herein as the “Company”) owns and operates Renasant Bank (“Renasant Bank” or the “Bank”) and Renasant Insurance, Inc. The Company offers a diversified range of financial, fiduciary and insurance services to its retail and commercial customers through its subsidiaries and full service offices located throughout north and central Mississippi, Tennessee, north and central Alabama, north Georgia and Florida.
Use of Estimates	Use of Estimates : The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Consolidation	Consolidation : In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic (“ASC”) 810, “Consolidation” (“ASC 810”), a company’s consolidated financial statements are required to include subsidiaries in which the company has a controlling financial interest. The accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements include the accounts of the Company and its consolidated subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to the current year presentation. The Company is not the primary beneficiary of any variable interest entity as defined by ASC 810.
Cash and Cash Equivalents	Cash and Cash Equivalents : The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Securities	Securities : Debt securities are classified as held to maturity when purchased if management has the positive intent and ability to hold the securities to maturity. Held to maturity securities are stated at amortized cost. Securities not classified as held to maturity or trading are classified as available for sale. Presently, the Company has no intention of establishing a trading classification. Available for sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive income within shareholders’ equity. The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts. Such amortization and accretion is included in interest income from securities. Dividend income is included in interest income from securities. Realized gains and losses on sales of securities are reflected under the line item “Net gains on sales of securities” on the Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. The Company evaluates its investment portfolio for other-than-temporary-impairment (“OTTI”) on a quarterly basis in accordance with ASC 320, “Investments - Debt and Equity Securities.” Impairment is assessed at the individual security level. The Company considers an investment security impaired if the fair value of the security is less than its cost or amortized cost basis. Impairment is considered to be other-than-temporary if the Company intends to sell the investment security or if the Company does not expect to recover the entire amortized cost basis of the security before the Company is required to sell the security or the security’s maturity. When impairment of an equity security is considered to be other-than-temporary, the security is written down to its fair value and an impairment loss is recorded as a loss within noninterest income in the Consolidated Statements of Income. When impairment of a debt security is considered to be other-than-temporary, the security is written down to its fair value. The amount of OTTI recorded as a loss within noninterest income depends on whether an entity intends to sell the debt security and whether it is more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis. If an entity intends to, or has decided to, sell the debt security or more likely than not will be required to sell the security before recovery of its amortized cost basis, OTTI must be recognized in earnings in an amount equal to the entire difference between the security’s amortized cost basis and its fair value. If an entity does not intend to sell the debt security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, OTTI is separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss is recognized in earnings and is calculated as the difference between the estimate of discounted future cash flows and the amortized cost basis of the security. A number of qualitative and quantitative factors, including but not limited to the financial condition of the underlying issuer and current and projected deferrals or defaults, are considered by management in the estimate of the discounted future cash flows. The remaining difference between the fair value and the amortized cost basis of the security is considered the amount related to other market factors and is recognized in other comprehensive income, net of applicable taxes. Furthermore, debt securities may be transferred to a nonaccrual status where the recognition of investment interest is discontinued. A number of qualitative factors, including but not limited to the financial condition of the underlying issuer and current and projected deferrals or defaults, are considered by management in the determination of whether the debt security should be transferred to nonaccrual status. The interest on these nonaccrual investment securities is accounted for on the cash-basis method until the debt security qualifies for return to accrual status. See Note C, “Securities,” for further details regarding the Company’s securities portfolio.
Securities sold under agreements to repurchase	Securities Sold Under Agreements to Repurchase : Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale : Mortgage loans held for sale represent residential mortgage loans held for sale. The Company has elected to carry these loans at fair value as permitted under the guidance in ASC 825, “Financial Instruments” (“ASC 825”). Mortgage loans held for sale are classified separately on the Consolidated Balance Sheets. Gains and losses are realized at the time consideration is received and all other criteria for sales treatment have been met. These realized and unrealized gains and losses are classified under the line item “Mortgage banking income” on the Consolidated Statements of Income.
Loans and the Allowance for Loan Losses	Loans and the Allowance for Loan Losses : Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses and any deferred fees or costs on originated loans. Renasant Bank defers certain nonrefundable loan origination fees as well as the direct costs of originating or acquiring loans. The deferred fees and costs are then amortized over the term of the note for all loans with payment schedules. Those loans with no payment schedule are amortized using the interest method. The amortization of these deferred fees is presented as an adjustment to the yield on loans. Interest income is accrued on the unpaid principal balance. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, the recognition of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer and other retail loans are typically charged-off no later than the time the loan is 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Loans may be placed on nonaccrual regardless of whether or not such loans are considered past due. All interest accrued for the current year, but not collected, for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Impairment is measured on a loan-by-loan basis for commercial and construction loans above a minimum dollar amount threshold by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are evaluated collectively for impairment. When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal. Once the recorded balance has been reduced to zero, future cash receipts are applied to interest income, to the extent any interest has been foregone, and then they are recorded as recoveries of any amounts previously charged-off. For impaired loans, a specific reserve is established to adjust the carrying value of the loan to its estimated net realizable value. Restructured loans are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition and are performing in accordance with the new terms. Such concessions may include reduction in interest rates or deferral of interest or principal payments. In evaluating whether to restructure a loan, management analyzes the long-term financial condition of the borrower, including guarantor and collateral support, to determine whether the proposed concessions will increase the likelihood of repayment of principal and interest. Restructured loans that are not performing in accordance with their restructured terms that are either contractually 90 days past due or have been placed on nonaccrual status are reported as nonperforming loans. See Note D, “Loans and the Allowance for Loan Losses,” for disclosures regarding the Company’s past due and nonaccrual loans, impaired loans and restructured loans. The allowance for loan losses is maintained at a level believed adequate by management to absorb probable credit losses inherent in the entire loan portfolio. The appropriate level of the allowance is based on an ongoing analysis of the loan portfolio and represents an amount that management deems adequate to provide for inherent losses, including collective impairment as recognized under ASC 450, “Contingencies”. Collective impairment is calculated based on loans grouped by grade. Another component of the allowance is losses on loans assessed as impaired under ASC 310, “Receivables” (“ASC 310”). The balance of these loans and their related allowance is included in management’s estimation and analysis of the allowance for loan losses. Management and the internal loan review staff evaluate the adequacy of the allowance for loan losses quarterly. The allowance for loan losses is evaluated based on a continuing assessment of problem loans, the types of loans, historical loss experience, new lending products, emerging credit trends, changes in the size and character of loan categories and other factors, including its risk rating system, regulatory guidance and economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance for loan losses is established through a provision for loan losses charged to earnings resulting from measurements of inherent credit risk in the loan portfolio and estimates of probable losses or impairments of individual loans. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.
Business Combinations, Accounting for Acquired Loans and Related Assets	Business Combinations, Accounting for Acquired Loans and Related Assets : Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations” (“ASC 805”). Under the acquisition method, identifiable assets acquired and liabilities assumed and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date and are recognized separately from goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Acquisition costs incurred by the Company are expensed as incurred. Loans acquired in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit-impaired. Acquired credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality, in accordance with ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC 310-30”), and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. Increases in expected cash flows to be collected on these loans are recognized as an adjustment of the loan’s yield over its remaining life, while decreases in expected cash flows are recognized as an impairment. In connection with the acquisition of specified assets and assumption of specified liabilities of Crescent Bank and Trust (“Crescent”) in July 2010 and American Trust Bank (“American Trust”) in February 2011, the Bank entered into loss-share agreements with the Federal Deposits Insurance Corporation (“FDIC”). Furthermore, in connection with the acquisition of Heritage, the Bank entered into two loss-sharing agreements with the FDIC which covered Citizens Bank of Effingham (“Citizens”) and First Southern National Bank (“First Southern”). Acquired loans covered under loss-share agreements with the FDIC are recorded, as of their respective acquisition dates, at fair value. The fair value of these loans represents the expected discounted cash flows to be received over the lives of the loans, taking into account the Company’s estimate of future credit losses on the loans. These loans are initially excluded from the calculation of the allowance for loan losses because the fair value measurement incorporates an estimate of losses on acquired loans. The Company monitors future cash flows on these loans; to the extent future cash flows deteriorate below initial projections, the Company reserves for these loans in the allowance for loan losses through the provision for loan losses. The Company recorded a provision for loan losses of $62 and $722 on account of the loans covered under loss-share agreements during the years ended December 31, 2015 and 2014 , respectively. In these Notes to Consolidated Financial Statements, the Company refers to loans acquired and subject to the loss-share agreements as “covered loans” or “loans covered under loss-share agreements” and loans acquired that are not subject to the loss-share agreements as “acquired non-covered loans” or “loans not covered under loss-share agreements.” As part of the loan portfolio and other real estate owned fair value estimation in connection with FDIC-assisted acquisitions, a FDIC loss-share indemnification asset is established, which represents the present value of the estimated losses on covered assets to be reimbursed by the FDIC. The estimated losses are based on the same cash flow estimates used in determining the fair value of the covered assets. The FDIC loss-share indemnification asset is reduced as losses are recognized on covered assets and loss-share payments are received from the FDIC. Realized losses in excess of estimates as of the date of the acquisition increase the FDIC loss-share indemnification asset. Conversely, when realized losses are less than these estimates, the portion of the FDIC loss-share indemnification asset no longer expected to result in a payment from the FDIC is amortized into interest income using the effective interest method.
Premises and Equipment	Premises and Equipment : Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily by use of the straight-line method for furniture, fixtures, equipment, autos and premises. The annual provisions for depreciation have been computed primarily using estimated lives of forty years for premises, seven years for furniture and equipment and three to five years for computer equipment and autos. Leasehold improvements are expensed over the period of the leases or the estimated useful life of the improvements, whichever is shorter.
Other Real Estate Owned	Other Real Estate Owned : Other real estate owned consists of properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure. These properties are initially recorded into other real estate at fair market value less cost to sell and are subsequently carried at the lower of cost or fair market value based on appraised value less estimated selling costs. Losses arising at the time of foreclosure of properties are charged against the allowance for loan losses. Reductions in the carrying value subsequent to acquisition are charged to earnings and are included under the line item “Other real estate owned” in the Consolidated Statements of Income.
Mortgage servicing rights	Mortgage Servicing Rights : The Company retains the right to service certain mortgage loans that it sells to secondary market investors. These mortgage servicing rights, included in “Other assets” on the Consolidated Balance Sheets, are recognized as a separate asset on the date the corresponding mortgage loan is sold. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income. These servicing rights are carried at the lower of amortized cost or fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, prepayment speeds, market discount rates, servicing costs, and other factors. Mortgage servicing rights were carried at amortized cost at December 31, 2015 and 2014 , respectively. Impairment losses on mortgage servicing rights are recognized to the extent by which the unamortized cost exceeds fair value.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets : Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangibles with finite lives are amortized over their estimated useful lives. Goodwill and other intangible assets are subject to impairment testing annually or more frequently if events or circumstances indicate possible impairment. Goodwill is assigned to the Company’s reporting segments. Fair values of reporting segments are determined using either discounted cash flow analyses based on internal financial forecasts or, if available, market-based valuation multiples for comparable businesses. Other intangible assets, consisting of core deposit intangibles, are reviewed for events or circumstances which could impact the recoverability of the intangible asset, such as a loss of core deposits, increased competition or adverse changes in the economy.
Bank-Owned Life Insurance	Bank-Owned Life Insurance : Bank-owned life insurance (“BOLI”) is an institutionally-priced insurance product that is specifically designed for purchase by insured depository institutions. The Company has purchased such insurance policies on certain employees, with Renasant Bank being listed as the primary beneficiary. The carrying value of BOLI is recorded at the cash surrender value of the policies, net of any applicable surrender charges.
Insurance Agency Revenues	Insurance Agency Revenues : Renasant Insurance, Inc. is a full-service insurance agency offering all lines of commercial and personal insurance through major third-party insurance carriers. Commissions and fees are recognized when earned based on contractual terms and conditions of insurance policies with the insurance carriers. These commissions and fees are classified under the line item “Insurance commissions” on the Consolidated Statements of Income. Contingency fee income paid by the insurance carriers is recognized upon receipt and classified under the line item “Other noninterest income” on the Consolidated Statements of Income.
Trust and Financial Services Revenue	Trust and Financial Services Revenues : The Company offers trust services as well as various alternative investment products, including annuities and mutual funds. Trust revenues are recognized on the accrual basis in accordance with the contractual terms of the trust. Commissions and fees from the sale of annuities and mutual funds are recognized when earned based on contractual terms with the third party broker-dealer. These commissions and fees are classified under the line item “Wealth management revenue” on the Consolidated Statements of Income.
Income Taxes	Income Taxes : Income taxes are accounted for under the liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. It is the Company’s policy to recognize interest and penalties, if incurred, related to unrecognized tax benefits in income tax expense. The Company and its subsidiaries file a consolidated federal income tax return. Renasant Bank provides for income taxes on a separate-return basis and remits to the Company amounts determined to be currently payable. Deferred income taxes, included in “Other assets” on the Consolidated Balance Sheets, reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes that the Company and its subsidiaries will realize a substantial majority of the deferred tax assets. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to be realized through a charge to income tax expense.
Fair Value Measurements	Fair Value Measurements : ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), provides guidance for using fair value to measure assets and liabilities and also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to a valuation based on quoted prices in active markets for identical assets and liabilities (Level 1), moderate priority to a valuation based on quoted prices in active markets for similar assets and liabilities and/or based on assumptions that are observable in the market (Level 2), and the lowest priority to a valuation based on assumptions that are not observable in the market (Level 3). See Note R, “Fair Value Measurements,” for further details regarding the Company’s methods and assumptions used to estimate the fair values of the Company’s financial assets and liabilities.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities : The Company utilizes derivative financial instruments as part of its ongoing efforts to manage its interest rate risk exposure. Derivative financial instruments are included in the Consolidated Balance Sheets line item “Other assets” or “Other liabilities” at fair value in accordance with ASC 815, “Derivatives and Hedging.” Cash flow hedges are utilized to mitigate the exposure to variability in expected future cash flows or other types of forecasted transactions. For the Company’s derivatives designated as cash flow hedges, changes in the fair value of cash flow hedges are, to the extent that the hedging relationship is effective, recorded as other comprehensive income and are subsequently recognized in earnings at the same time that the hedged item is recognized in earnings. The ineffective portions of the changes in fair value of the hedging instruments are immediately recognized in earnings. The assessment of the effectiveness of the hedging relationship is evaluated under the hypothetical derivative method. The Company also utilizes derivative instruments that are not designated as hedging instruments. The Company enters into interest rate cap and/or floor agreements with its customers and then enters into an offsetting derivative contract position with other financial institutions to mitigate the interest rate risk associated with these customer contracts. Because these derivative instruments are not designated as hedging instruments, changes in the fair value of the derivative instruments are recognized currently in earnings. The Company enters into interest rate lock commitments on certain residential mortgage loans with its customers to mitigate the interest rate risk associated with the commitments to fund fixed-rate mortgage loans. Under such commitments, interest rates for a mortgage loan are typically locked in for up to forty-five days with the customer. These interest rate lock commitments are recorded at fair value in the Company’s Consolidated Balance Sheets. Gains and losses arising from changes in the valuation of the commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income. The Company utilizes two methods to deliver mortgage loans to be sold to an investor. Under a “best efforts” sales agreement, the Company enters into a sales agreement with an investor in the secondary market to sell the loan when an interest rate lock commitment is entered into with a customer, as described above. Under a “best efforts” sales agreement, the Company is obligated to sell the mortgage loan to the investor only if the loan is closed and funded. Thus, the Company will not incur any liability to an investor if the mortgage loan commitment in the pipeline fails to close. Under a mandatory delivery sales agreement, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price and delivery date. Penalties are paid to the investor should the Company fail to satisfy the contract. Mandatory delivery mortgage loan commitments are recorded at fair value in the Company’s Consolidated Balance Sheets. Gains and losses arising from changes in the valuation of these commitments are recognized currently in earnings and are reflected under the line item “Mortgage banking income” on the Consolidated Statements of Income.
Treasury Stock	Treasury Stock : Treasury stock is recorded at cost. Shares held in treasury are not retired.
Retirement Plans	Retirement Plans : The Company sponsors a noncontributory pension plan and provides retiree heath care benefits for certain employees. Our independent actuary firm prepares actuarial valuations of our pension cost and obligation under ASC 715, “Compensation – Retirement Benefits” ("ASC 715") using assumptions and estimates derived in accordance with the guidance set forth in ASC 715. Expense related to the plans is included under the line item "Salaries and employee benefits" on the Consolidated Statements of Income. Actuarial gains and losses are recognized in accumulated other comprehensive income, net of tax, until they are amortized as a component of plan expense.
Stock-Based Compensation	Stock-Based Compensation : Compensation expense for option grants and restricted stock awards is determined based on the estimated fair value of the stock options and restricted stock on the applicable grant or award date. Further, compensation expense is based on an estimate of the number of option grants expected to vest and is recognized over the option’s vesting period. The Company did not estimate any option forfeitures for 2015 , 2014 or 2013 due to the low historical forfeiture rate. Expense associated with the Company’s stock-based compensation is included under the line item “Salaries and employee benefits” on the Consolidated Statements of Income. The Company recognizes compensation expense for all share-based payments to employees in accordance with ASC 718, “Compensation – Stock Compensation.” See Note N, “Employee Benefit and Deferred Compensation Plans,” for further details regarding the Company’s stock-based compensation.
Earnings Per Common Share	Earnings Per Common Share : Basic net income per common share is calculated by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted net income per common share reflects the pro forma dilution assuming outstanding stock options were exercised into common shares, calculated in accordance with the treasury stock method. See Note W, “Net Income Per Common Share,” for the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations.
Impact of Recently-Issued Accounting Standards and Pronouncements	Impact of Recently-Issued Accounting Standards and Pronouncements : In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20) –Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for interim and annual periods beginning after December 15, 2015. ASU 2015-01 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which amends the consolidation requirements of ASU 810 by changing the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015. ASU 2015-02 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures. In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. In August 2015, the FASB issued ASU 2015-15 to clarify the Securities and Exchange Commission (“SEC”) staff’s position on presenting and measuring debt issue costs related to line-of-credit arrangements. ASU 2015-03 and ASU 2015-15 are effective for interim and annual periods beginning after December 15, 2015. ASU 2015-03 and ASU 2015-15 are not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures. In September 2015, the FASB issued ASU 2015-16 “Simplifying the Accounting for Measurement-Period Adjustments.” ASU 2015-16 requires entities to recognize measurement period adjustments during the reporting period in which the adjustments are determined. The income effects, if any, of a measurement period adjustment are cumulative and are to be reported in the period in which the adjustment to a provisional amount is determined. Also, ASU 2015-16 requires presentation on the face of the income statement or in the notes the effect of the measurement period adjustment as if the adjustment had been recognized at acquisition date. ASU 2015-16 is effective for fiscal periods beginning after December 15, 2016 and should be applied prospectively to measurement period adjustments that occur after the effective date. The Company is evaluating the impact that ASU 2015-16 will have on its financial position, results of operations, and its financial statement disclosures. In November 2015, the FASB issued ASU 2015-17 “Balance Sheet Classification of Deferred Taxes.” ASU 2015-17 requires all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for fiscal periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is evaluating the impact that ASU 2015-17. In January 2016, FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 revises the accounting for the classification and measurement of investments in equity securities and revises the presentation of certain fair value changes for financial liabilities measured at fair value. For equity securities, the guidance in ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income. For financial liabilities that are measured at fair value in accordance with the fair value option, the guidance requires presenting, in other comprehensive income, the change in fair value that relates to a change in instrument-specific credit risk. ASU 2016-01 also eliminates the disclosure assumptions used to estimate fair value for financial instruments measured at amortized cost and requires disclosure of an exit price notion in determining the fair value of financial instruments measured at amortized cost. ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017. The Company is evaluating the impact, if any, that ASU 2016-01 will have on its financial position, results of operations, and its financial statement disclosures. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)” . ASU 2016-02 amends the accounting model and disclosure requirements for leases. The current accounting model for leases distinguishes between capital leases, which are recognized on-balance sheet, and operating leases, which are not. Under the new standard, the lease classifications are defined as finance leases, which are similar to capital leases under current U.S. GAAP, and operating leases. Further, a lessee will recognize a lease liability and a right-of-use asset for all leases with a term greater than 12 months on its balance sheet regardless of the lease’s classification, which may significantly increase reported assets and liabilities. The accounting model and disclosure requirements for lessors remains substantially unchanged from current U.S. GAAP. ASU 2016-02 is effective for annual and interim periods in fiscal years beginning after December 15, 2018. The Company is evaluating the impact ASU 2016-02 will have on its financial position, results of operations, and other financial disclosures. Proposed Accounting Pronouncements – In December 2012, the FASB announced a project related to the impairment of financial instruments in an effort to provide new guidance that would significantly change how entities measure and recognize credit impairment for certain financial assets. While completion of the project and related guidance is still pending, it is anticipated that new guidance will replace the current incurred loss model that is utilized in estimating the allowance for loan and lease losses with a model that requires management to estimate all contractual cash flows that are not expected to be collected over the life of the loan. The FASB describes this revised model as the current expected credit loss (“CECL”) model and believes the CECL model will result in more timely recognition of credit losses since the CECL model incorporates expected credit losses versus incurred credit losses. The proposed scope of FASB’s CECL model would include loans, held-to-maturity debt instruments, lease receivables, loan commitments and financial guarantees that are not accounted for at fair value. The final issuance date and the implementation date of the CECL guidance is currently pending, and the Company will continue to monitor FASB’s progress on this topic.
