Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (Dollar amounts in thousands) 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. Through its subsidiaries, the Company offers a diversified range of financial, wealth management, fiduciary and insurance services to its retail and commercial customers from full service offices located throughout north and central Mississippi, Tennessee, Alabama, Georgia and Florida. Use of Estimates : The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) 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 : 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. Reclassifications had no effect on prior years’ net income or shareholders’ equity. 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. Presently, the Company has no intention of establishing a trading classification. Securities not classified as held to maturity or trading are classified as available for sale. 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, regardless of classification, is adjusted for amortization of premiums and accretion of discounts. Such amortization and accretion is included in interest income from securities, as is dividend income. Realized gains and losses on sales of securities are reflected under the line item “Net gains (losses) 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic (“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. Recognition of investment interest is discontinued on debt securities that are transferred to nonaccrual status. 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 nonaccrual investment securities is accounted for on the cash-basis method until the debt security qualifies for return to accrual status. See Note 3, “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. Loans Held for Sale : Residential mortgage loans held for sale are included in the line item “Loans held for sale” on the Company’s Consolidated Balance Sheets. The Company has elected to carry these loans at fair value as permitted under the guidance in ASC 825, “Financial Instruments” (“ASC 825”). 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. In connection with the acquisition of Brand (as defined below in Note 2, “Mergers and Acquisitions”), the Company acquired a portfolio of non-mortgage consumer loans, which were also included in the line item “Loans held for sale” on the Company’s Consolidated Balance Sheet as of December 31, 2018. During 2019, the Company made the decision to hold the portfolio for the foreseeable future and therefore transferred the loans from the held for sale category to the held for investment category. While these non-mortgage consumer loans were classified as held for sale, the Company carried these loans at the lower of amortized cost or fair value. Loans and the Allowance for Loan Losse s: 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, any deferred fees or costs on originated loans and any purchase discounts or premiums on purchased 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. 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 and industrial 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, as applicable, 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. 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. See Note 4, “ Non Purchased Loans,” Note 5, “Purchased Loans,” and Note 6, “ Allowance for Loan Losses” for disclosures regarding the Company’s past due and nonaccrual loans, impaired loans and restructured loans and its allowance for loan losses. Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets : Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations.” 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 purchased 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. Purchased credit deteriorated loans are accounted for 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. 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, three to 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. Effective January 1, 2019, ASC 842, “Leases” requires a lessee to recognize a right-of-use asset and a lease liability for all leases with a term greater than twelve months on its balance sheet regardless of the whether the lease is classified as financing or operating. All of the Company’s lessee arrangements are operating leases, being real estate leases for Company facilities. Under these arrangements, the Company records right-of-use assets and corresponding lease liabilities, each of which is based on the present value of the remaining lease payments and are discounted at the Company’s incremental borrowing rate. Right-of-use assets are reported in premises and equipment on the Consolidated Balance Sheets and the related lease liabilities are reported in other liabilities. All leases are recorded on the Consolidated Balance Sheets except for leases with an initial term less than 12 months for which the Company elected the short-term lease recognition exemption. Lease terms may contain renewal and extension options and early termination features. Many leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or more. The exercise of lease renewal options is at the Company’s sole discretion. Renewal options which are reasonably certain to be exercised in the future were included in the measurement of right-of-use assets and lease liabilities. Lease expense is recognized on a straight-line basis over the lease term and is recorded in occupancy and equipment expense in the Consolidated Statements of Income. Variable lease payments consist primarily of common area maintenance and taxes. The Company does not have any material sublease agreements currently in place. 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” on 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 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, mortgage interest rates and other factors. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is recognized through a valuation allowance, to the extent that unamortized cost exceeds fair value. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the valuation allowance may be recorded as an increase to income. Changes in valuation allowances related to servicing rights are reported in the line item “Mortgage banking income” on the Consolidated Statements of Income. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. 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 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. In determining the fair value of the Company’s reporting units, management uses the market approach. Other intangible assets, consisting of core deposit intangibles and customer relationship 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 2019 , 2018 or 2017 . 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. In connection with the acquisition of Brand (as defined below in Note 2, “Mergers and Acquisitions”), the Company acquired BOLI with a cash surrender value of $40,081 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. Revenue from Contracts with Customers : ASC 606, “Revenue from Contracts with Customers,” provides guidance on revenue recognition from contracts with customers. For revenue streams within its scope, ASC 606 requires costs that are incremental to obtaining a contract to be capitalized. In the case of the Company, these costs include sales commissions for insurance and wealth management products. ASC 606 has established, and the Company has utilized, a practical expedient allowing costs that, if capitalized, would have an amortization period of one year or less to instead be expensed as incurred. Service Charges on Deposit Accounts Service charges on deposit accounts include maintenance fees on accounts, per item charges, account enhancement charges for additional packaged benefits and overdraft fees. The contracts with deposit account customers are day-to-day contracts and are considered to be terminable at will by either party. Therefore, the fees are all considered to be earned when charged and simultaneously collected. Fees and Commissions Fees and commissions include fees related to deposit services, such as ATM fees and interchange fees on debit card transactions. These fees are earned at the point in time when the services are rendered, and therefore the related revenue is recognized as the Company’s performance obligation is satisfied. Insurance Commissions Insurance commissions are earned when policies are placed by customers with the insurance carriers and are collected and recognized using two different methods: the agency bill method and the direct bill method. Under the agency bill method, Renasant Insurance is responsible for billing the customers directly and then collecting and remitting the premiums to the insurance carriers. Agency bill revenue is recognized at the later of the invoice date or effective date of the policy. The Company has established a reserve for such policies which is derived from historical collection experience and updated annually. The contract balances (i.e. accounts receivable and accounts payable related to insurance commissions earned and premiums due) and the reserve established are considered inconsequential to the overall financial results of the Company. Under the direct bill method, premium billing and collections are handled by the insurance carriers, and a commission is then paid to Renasant Insurance. Direct bill revenue is recognized when the cash is received from the insurance carriers. While there is recourse on these commissions in the event of policy cancellations, based on the Company’s historical data, significant or material reversals of revenue based on policy cancellations are not anticipated. The Company monitors policy cancellations on a monthly basis and, if a significant or material set of transactions were to occur, the Company would adjust earnings accordingly. The Company also earns contingency income that it recognizes on a cash basis. Contingency income is a bonus received from the insurance underwriters and is based on commission income and claims experience on the Company’s clients’ policies during the previous year. Increases and decreases in contingency income are reflective of corresponding increases and decreases in the amount of claims paid by insurance carriers. Wealth Management Revenue Fees for managing trust accounts (inclusive of personal and corporate benefit accounts, self-directed IRAs, and custodial accounts) are based on the value of assets under management in the account, with the amount of the fee depending on the type of account. Revenue is recognized on a monthly basis, and there is little to no risk of a material reversal of revenue. Fees for other wealth management services, such as investment guidance relating to fixed and variable annuities, mutual funds, stocks and other investments, are recognized based on either trade activity, which are recognized at the time of the trade, or assets under management, which are recognized monthly. Sales of Other Real Estate Owned The Company continually markets the properties included in the OREO portfolio. The Company will at times, in the ordinary course of business, provide seller-financing on sales of OREO. In cases where a sale is seller-financed, the Company must ensure the commitment of both parties to perform their respective obligations and the collectability of the transaction price in order to properly recognize the revenue on the sale of OREO. This is accomplished through the Company’s loan underwriting process. In this process the Company considers things such as the buyer’s initial equity in the property, the credit quality of the buyer, the financing terms of the loan and the cash flow from the property, if applicable. If it is determined that the contract criteria in ASC 606 have been met, the revenue on the sale of OREO will be recognized on the closing date of the sale when the Company has transferred title to the buyer and obtained the right to receive payment for the property. In instances where sales are not seller-financed, the Company recognizes revenue on the closing date of the sale when the Company has obtained payment for the property and transferred title to the buyer. For additional information on OREO, please see Note 8, “Other Real Estate Owned.” 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,” 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 17, “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 45 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. These types of 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 medical benefits for certain employees. The Company’s independent actuary firm prepares actuarial valuations of pension cost and obligati

Mergers and Acquisitions	Mergers and Acquisitions (Dollar amounts in thousands, except per share data) Acquisition of Brand Group Holdings, Inc. Effective September 1, 2018, the Company completed its acquisition by merger of Brand Group Holdings, Inc. (“Brand”), the parent company of The Brand Banking Company (“Brand Bank”), in a transaction valued at approximately $474,453 . The Company issued 9,306,477 shares of common stock and paid approximately $21,879 to Brand shareholders, excluding cash paid for fractional shares, and paid approximately $17,157 , net of tax benefit, to Brand stock option holders for 100% of the voting equity interest in Brand. At closing, Brand merged with and into the Company, with the Company the surviving corporation in the merger; immediately thereafter, Brand Bank merged with and into Renasant Bank, with Renasant Bank the surviving banking corporation in the merger. On September 1, 2018, Brand operated thirteen banking locations throughout the greater Atlanta market. The Company recorded approximately $356,171 in intangible assets, which consist of goodwill of $328,637 and a core deposit intangible of $27,534 . Goodwill resulted from a combination of revenue enhancements from expansion in existing markets and efficiencies resulting from operational synergies. The fair value of the core deposit intangible is being amortized 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 Brand based on their fair values on September 1, 2018. Purchase Price: Shares issued to common shareholders 9,306,477 Purchase price per share $ 46.69 Value of stock paid $ 434,519 Cash consideration paid 21,879 Cash paid for fractional shares 4 Cash settlement for stock options, net of tax benefit 17,157 Deal charges paid on behalf of Brand 894 Total Purchase Price $ 474,453 Net Assets Acquired: Stockholders’ equity at acquisition date $ 138,896 Increase (decrease) to net assets as a result of fair value adjustments to assets acquired and liabilities assumed: Securities (323 ) Loans, including loans held for sale (27,611 ) Premises and equipment 910 Intangible assets 27,534 Other assets (4,495 ) Deposits (1,367 ) Borrowings (2,023 ) Other liabilities 13,338 Deferred income taxes 957 Total Net Assets Acquired 145,816 Goodwill resulting from merger (1) $ 328,637 (1) The goodwill resulting from the merger has been assigned to the Community Banks operating segment. The following table summarizes the estimated fair value on September 1, 2018 of assets acquired and liabilities assumed on that date in connection with the merger with Brand: Cash and cash equivalents $ 193,436 Securities 71,122 Loans, including loans held for sale 1,580,339 Premises and equipment 20,070 Intangible assets 356,171 Other assets 113,195 Total assets 2,334,333 Deposits 1,714,177 Borrowings 89,273 Other liabilities 56,430 Total liabilities 1,859,880 As part of the merger agreement, Brand agreed to divest the operations of its subsidiary Brand Mortgage Group, LLC (“BMG”), which transaction was completed as of October 31, 2018. As a result, the balance sheet and results of operations of BMG, which the Company considers to be immaterial to the overall results of the Company, were included in the Company’s balance sheet and consolidated results of operations from September 1, 2018 to October 31, 2018. The following table summarizes the significant assets acquired and liabilities assumed from BMG: (in thousands) September 1, 2018 Loans held for sale 48,100 Borrowings 34,139 The following table summarizes the results of operations for BMG included in the Company’s Consolidated Statements of Income for the twelve months ended December 31, 2018: (in thousands) Interest income $ 357 Interest expense 279 Net interest income 78 Noninterest income 4,043 Noninterest expense 4,398 Net loss before taxes $ (277 ) Supplemental Pro Forma Combined Condensed Results of Operations The following unaudited pro forma combined condensed consolidated financial information presents the results of operations for the twelve months ended December 31, 2019 and 2018 of the Company as though the Brand merger had been completed as of January 1, 2018, except that the results of operations for BMG are only included through its October 31, 2018 divestiture. The unaudited estimated pro forma information combines the historical results of Brand 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 necessarily indicative of what would have occurred had the acquisitions taken place on January 1, 2018. 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, 2019 2018 Net interest income - pro forma (unaudited) $ 443,657 $ 455,513 Noninterest income - pro forma (unaudited) $ 153,254 $ 153,850 Noninterest expense - pro forma (unaudited) $ 374,174 $ 452,699 Net income - pro forma (unaudited) $ 167,596 $ 115,646 Earnings per share - pro forma (unaudited): Basic $ 2.89 $ 1.97 Diluted $ 2.88 $ 1.97 Due to the timing of the respective system conversions and the integration of operations into the Company’s existing operations, historical reporting for acquired operations is impracticable, and, therefore, disclosure of the amounts of revenue and expenses of the acquired institutions since the acquisition dates is impracticable.

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 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, 2019 and 2018 . The Company holds investments in pooled trust preferred securities that had a cost basis of $12,153 and $12,359 and a fair value of $9,986 and $10,633 at December 31, 2019 and 2018 , respectively. As of December 31, 2019 , the investments in pooled trust preferred securities consisted of two securities representing interests in various tranches of trusts collateralized by debt issued by 148 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 before recovery of the investments' amortized cost, 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, 2019 , management did not, and does not currently, believe such securities will be settled at a price less than the amortized cost of each investment, but the Company previously concluded that it was probable that there had been an adverse change in estimated cash flows for both trust preferred securities and recognized credit related impairment losses on these securities in 2011. For the years ended December 31, 2019 , 2018 and 2017 , 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 had no remaining availability under commitments to lend additional funds on these restructured loans at December 31, 2019 and $42 in remaining availability under commitments to lend additional funds on these restructured loans at December 31, 2018 . 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 within the “Pass” grade (historically, those with a risk rating between 1 and 4 ) generally have a lower risk of loss and therefore a lower risk factor applied to the loan balances. The “Pass” grade is reserved for loans with a risk rating between 1 and 4A, and the “Watch” grade (those with a risk rating of 4B and 4E) is utilized on a temporary basis for “Pass” grade loans where a significant adverse risk-modifying action is anticipated in the near term. Loans that migrate toward the “Substandard” grade (those with a risk rating between 5 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, 2019 Commercial, financial, agricultural $ 779,798 $ 11,949 $ 11,715 $ 803,462 Real estate – construction 698,950 501 9,209 708,660 Real estate – 1-4 family mortgage 339,079 3,856 3,572 346,507 Real estate – commercial mortgage 2,737,629 31,867 26,711 2,796,207 Installment loans to individuals 6 — — 6 Total $ 4,555,462 $ 48,173 $ 51,207 $ 4,654,842 December 31, 2018 Commercial, financial, agricultural $ 615,803 $ 18,326 $ 6,973 $ 641,102 Real estate – construction 558,494 2,317 8,157 568,968 Real estate – 1-4 family mortgage 321,564 4,660 4,260 330,484 Real estate – commercial mortgage 2,210,100 54,579 24,144 2,288,823 Installment loans to individuals — — — — Total $ 3,705,961 $ 79,882 $ 43,534 $ 3,829,377 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.

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 within the “Pass” grade (historically, those with a risk rating between 1 and 4 ) generally have a lower risk of loss and therefore a lower risk factor applied to the loan balances. The “Pass” grade is reserved for loans with a risk rating between 1 and 4A, and the “Watch” grade (those with a risk rating of 4B and 4E) is utilized on a temporary basis for “Pass” grade loans where a significant adverse risk-modifying action is anticipated in the near term. Loans that migrate toward the “Substandard” grade (those with a risk rating between 5 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, 2019 Commercial, financial, agricultural $ 779,798 $ 11,949 $ 11,715 $ 803,462 Real estate – construction 698,950 501 9,209 708,660 Real estate – 1-4 family mortgage 339,079 3,856 3,572 346,507 Real estate – commercial mortgage 2,737,629 31,867 26,711 2,796,207 Installment loans to individuals 6 — — 6 Total $ 4,555,462 $ 48,173 $ 51,207 $ 4,654,842 December 31, 2018 Commercial, financial, agricultural $ 615,803 $ 18,326 $ 6,973 $ 641,102 Real estate – construction 558,494 2,317 8,157 568,968 Real estate – 1-4 family mortgage 321,564 4,660 4,260 330,484 Real estate – commercial mortgage 2,210,100 54,579 24,144 2,288,823 Installment loans to individuals — — — — Total $ 3,705,961 $ 79,882 $ 43,534 $ 3,829,377 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.

The Company did not prepay any outstanding long-term advances from the FHLB during 2018 or 2017 . Junior subordinated debentures The Company owns the outstanding common securities of business trusts that issued corporation-obligated mandatorily redeemable preferred capital securities to third-party investors. The trusts used the proceeds from the issuance of their preferred capital securities and common securities (collectively referred to as “capital securities”) to buy floating rate junior subordinated debentures issued by the Company (or by companies that the Company subsequently acquired). The debentures are the trusts’ only assets and interest payments from the debentures finance the distributions paid on the capital securities. 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 of each trust subject to the terms of the guarantee. The following table provides details on the debentures as of December 31, 2019 : Principal Amount Interest Rate Year of Maturity Amount Included in Tier 1 Capital PHC Statutory Trust I $ 20,619 4.75 % 2033 $ 20,000 PHC Statutory Trust II 31,959 3.76 2035 31,000 Capital Bancorp Capital Trust I 12,372 3.46 2035 12,000 First M&F Statutory Trust I 30,928 3.22 2036 21,098 Brand Group Holdings Statutory Trust I 10,310 3.99 2035 9,108 Brand Group Holdings Statutory Trust II 5,155 4.89 2037 5,058 Brand Group Holdings Statutory Trust III 5,155 4.89 2038 5,058 Brand Group Holdings Statutory Trust IV 3,093 5.64 2038 3,302 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 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 the Company receives a variable rate of interest based on the three-month LIBOR plus a spread of 1.50% and pays 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 Corporation (“First M&F”) in 2013, 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 $8,902 at December 31, 2019 and $9,450 at December 31, 2018 .

The debentures owned by the respective trusts listed above are all currently redeemable at par. The net discount associated with the Company’s assumption of the debentures issued to the respective Brand trusts had a carrying value of $474 at December 31, 2019 and is being amortized through September 2038. The Company has classified $106,624 of the debentures described in the above paragraphs as Tier 1 capital. Federal Reserve guidelines limit the amount of securities that, similar to our junior subordinated debentures, are includable in Tier 1 capital, but these guidelines did not impact the amount of debentures we include in Tier 1 capital. Although our existing junior subordinated debentures are currently unaffected by these Federal Reserve guidelines, on account of changes enacted as part of the Dodd-Frank Act, any new trust preferred securities are not includable in Tier 1 capital. Further, if as a result of an acquisition we exceed $15,000,000 in assets, or if we make any acquisition after we have exceeded $15,000,000 in assets, we will lose Tier 1 treatment of our junior subordinated debentures. For more information about the Company’s derivative financial instruments, see Note 15, “Derivative Instruments.” Subordinated notes On August 22, 2016, the Company issued and sold in an underwritten public offering $60,000 aggregate principal amount of its 5.00% Fixed-to-Floating Rate Subordinated Notes due 2026 (the “2026 Notes”) and $40,000 aggregate principal amount of its 5.50% Fixed-to-Floating Rate Subordinated Notes due 2031 (the “2031 Notes”), at a public offering price equal to 100% of the aggregate principal amounts of the Notes. As part of the Metropolitan BancGroup, Inc. (“Metropolitan”; the 2026 Notes, the 2031 Notes and the Metropolitan Notes are referred to collectively as the “Notes”) acquisition in 2017, the Company assumed $15,000 of 6.50% Fixed-to-Floating Rate Subordinated Notes due 2026 (the “Metropolitan Notes”). As part of the Brand acquisition in 2018, the Company assumed $30,000 of 8.50% Fixed Rate Subordinated Notes due 2024 (the “Brand Notes”). During 2019, the Company redeemed the Brand Notes and incurred a debt prepayment penalty of $900 , which was accounted for in the purchase accounting fair value adjustment. The Metropolitan Notes, 2026 Notes and 2031 Notes mature on July 1, 2026, September 1, 2026 and on September 1, 2031, respectively. Until but excluding July 1, 2021, the Company pays interest on the Metropolitan Notes semi-annually in arrears on each January 1 and July 1 at a fixed annual interest rate equal to 6.50% . From and including July 1, 2021 to but excluding the maturity date or the date of earlier redemption, the interest rate on the Metropolitan Notes will reset quarterly to an annual interest rate equal to the then-current three-month LIBOR rate plus a spread of 554.5 basis points, payable quarterly in arrears on each January 1, April 1, July 1 and October 1. Until but excluding September 1, 2021 and 2026, respectively, the Company pays interest on the 2026 Notes and 2031 Notes semi-annually in arrears on each March 1 and September 1 at a fixed annual interest rate equal to 5.00% and 5.50% , respectively. From and including September 1, 2021 and 2026, respectively, to but excluding the maturity date or the date of earlier redemption, the interest rate on the 2026 Notes and 2031 Notes will reset quarterly to an annual interest rate equal to the then-current three-month LIBOR rate plus a spread of 384 basis points and 407.1 basis points, respectively, payable quarterly in arrears on each March 1, June 1, September 1 and December 1. Notwithstanding the foregoing, for all of the Notes, in the event that three-month LIBOR is less than zero , three-month LIBOR shall be deemed to be zero . Beginning with the interest payment date of July 1, 2021, as to the Metropolitan Notes, September 1, 2021 as to the 2026 Notes, and September 1, 2026, as to the 2031 Notes, and on any interest payment date thereafter, the Company may redeem the applicable Notes in whole or in part at a redemption price equal to 100% of the principal amount of the respective Notes to be redeemed plus accrued and unpaid interest to but excluding the date of redemption. The Company may also redeem any series of the Notes at any time, at the Company’s option, in whole or in part, if: (i) a change or prospective change in law occurs that could prevent the Company from deducting interest payable on the Notes for U.S. federal income tax purposes; (ii) a subsequent event occurs that could preclude the Notes from being recognized as Tier 2 capital for regulatory capital purposes; or (iii) the Company is required to register as an investment company under the Investment Company Act of 1940, as amended. In each case, the redemption price is 100% of the principal amount of the Notes being redeemed plus any accrued and unpaid interest to but excluding the redemption date.

Retirement Benefits [Abstract]
Employee Benefit and Deferred Compensation Plans	Employee Benefit and Deferred Compensation Plans (In Thousands, Except Share Data) Pension and Post-retirement Medical Plans The Company sponsors a noncontributory defined benefit pension plan, under which participation and benefit accruals ceased as of December 31, 1996. The Company’s funding policy is to contribute annually to the plan an amount not less than the minimum required contribution, as determined annually by consulting actuaries in accordance with funding standards imposed under the Internal Revenue Code of 1986, as amended. No contributions were made or required in 2019 or 2018 . The Company does not anticipate that a contribution will be required in 2020 . The plan’s accumulated benefit obligation and projected benefit obligation are substantially the same since benefit accruals have ceased. The accumulated benefit obligation was $28,020 and $24,945 at December 31, 2019 and 2018 , respectively. There is no additional minimum pension liability required to be recognized. The Company provides retiree medical benefits, consisting of the opportunity to purchase coverage at subsidized rates under the Company’s group medical plan. Employees eligible to participate must: (i) have been employed by the Company and enrolled in the Company’s group medical plan as of December 31, 2004; and (ii) retire from the Company between ages 55 and 65 with at least 15 years of service or 70 points (points determined as the sum of age and service). The Company periodically determines the portion of the premiums to be paid by each retiree and the portion to be paid by the Company. Coverage ceases when a retiree attains age 65 and is eligible for Medicare. The Company contributed $151 and $89 to the plan in 2019 and 2018 , respectively; the Company expects to contribute approximately $155 in 2020 . The Company accounts for its obligations related to 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., the health care cost trend rate) for 2020 is 4.8% . 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, 2019 and for the year then ended. Information relating to the defined benefit pension plan maintained by Renasant Bank (“Pension Benefits - Renasant”) and to the post-retirement health and life plan (“Other Benefits”) as of December 31, 2019 and 2018 is as follows: Pension Benefits Renasant Other Benefits 2019 2018 2019 2018 Change in benefit obligation Benefit obligation at beginning of year $ 24,945 $ 27,859 $ 881 $ 1,170 Service cost — — 7 8 Interest cost 1,176 1,043 31 31 Plan participants’ contributions — — 60 75 Actuarial loss (gain) 3,671 (2,016 ) (60 ) (239 ) Benefits paid (1,772 ) (1,941 ) (212 ) (164 ) Benefit obligation at end of year $ 28,020 $ 24,945 $ 707 $ 881 Change in fair value of plan assets Fair value of plan assets at beginning of year $ 25,206 $ 26,913 Actual return on plan assets 5,151 234 Contribution by employer — — Benefits paid (1,772 ) (1,941 ) Fair value of plan assets at end of year $ 28,585 $ 25,206 Funded status at end of year $ 565 $ 261 $ (707 ) $ (881 ) Weighted-average assumptions as of December 31 Discount rate used to determine the benefit obligation 3.59 % 4.56 % 2.91 % 4.07 % The discount rate assumptions at December 31, 2019 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 plans. The selected discount rate is the rate that produces the same present value of the plans’ 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 years ended December 31, 2019 , 2018 and 2017 are as follows: Pension Benefits Renasant Other Benefits 2019 2018 2017 2019 2018 2017 Service cost $ — $ — $ — $ 7 $ 8 $ 9 Interest cost 1,176 1,043 1,168 31 31 42 Expected return on plan assets (1,450 ) (2,077 ) (1,941 ) — — — Prior service cost recognized — — — — — — Recognized actuarial loss 442 328 401 (23 ) — 6 Settlement/curtailment/termination losses — — — — — — Net periodic benefit cost 168 (706 ) (372 ) 15 39 57 Net actuarial (gain) loss arising during the period (31 ) (173 ) (1,051 ) (60 ) (240 ) (328 ) Net Settlement/curtailment/termination losses — — — — — — Amortization of net actuarial loss recognized in net periodic pension cost (442 ) (328 ) (401 ) 23 — (6 ) Total recognized in other comprehensive income (473 ) (501 ) (1,452 ) (37 ) (240 ) (334 ) Total recognized in net periodic benefit cost and other comprehensive income $ (305 ) $ (1,207 ) $ (1,824 ) $ (22 ) $ (201 ) $ (277 ) Weighted-average assumptions as of December 31 Discount rate used to determine net periodic pension cost 4.56 % 3.96 % 4.35 % 4.07 % 3.37 % 3.57 % Expected return on plan assets 6.00 % 6.00 % 8.00 % N/A N/A N/A Future estimated benefit payments under the Renasant defined benefit pension plan and post-retirement health and life plan are as follows: Pension Benefits Renasant Other Benefits 2020 $ 2,131 $ 155 2021 2,146 133 2022 2,145 103 2023 2,127 94 2024 2,105 86 2025 - 2029 9,763 195 Amounts recognized in accumulated other comprehensive income, before tax, for the year ended December 31, 2019 are as follows: Pension Benefits Renasant Other Benefits Prior service cost $ — $ — Actuarial loss (gain) 9,090 (192 ) Total $ 9,090 $ (192 ) 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 Other Benefits Prior service cost $ — $ — Actuarial loss (gain) 318 (67 ) Total $ 318 $ (67 ) Prior to 2018, the investment objective of the Company’s defined benefit plan was to achieve above average income and moderate long-term growth, by combining an equity income strategy (allocation of 65% to 75% of assets) and an intermediate fixed income strategy (allocation of 25% to 35% of assets) and investing directly in debt and equity securities. In 2018, the Company’s investment committee modified the strategy by focusing on portfolio growth and including interest rate hedging, both of which were intended to preserve the funded status of the plan. Substantially, all of the plan’s assets were liquidated and the proceeds reinvested in a collective trust, which in turn invests in other collective or pooled trusts with individual investment mandates. The collective trust’s asset allocation is approximately 55% in growth assets, consisting of interests in trusts invested in equity securities, high yield fixed income securities, and direct real estate investments (approximately 5% of assets), and approximately 45% in assets intended to hedge against the volatility arising from interest rate risk, consisting of interests in trusts invested in long duration fixed income securities. The collective trust is actively managed allowing changes in the asset allocation to enhance returns and mitigate risk. Management’s trust investment committee periodically reviews the collective trust’s performance and asset allocation to ensure that the plan’s investment objectives are satisfied and that the investment strategy of the trust has not materially changed. The expected long-term rate of return was estimated using market benchmarks for investment classes applied to the plan’s target asset allocation and was computed using a valuation methodology which projects future returns based on current valuations rather than historical returns. The decrease in the expected return for 2018 (as compared to 2017) is attributable to the change in investment strategy, which resulted in a more conservative asset allocation. The fair values of the Company’s defined benefit pension plan assets by category at December 31, 2019 and 2018 are below. Investments in collective trusts, which are measured at net asset value per share (or “NAV”), consist of trusts that invest primarily in liquid equity and fixed income securities and have a small direct investment in real estate. There is generally no restriction on redemptions or withdrawals for benefit payments or in the event of plan termination; 60 days notice is required to redeem or withdraw assets for any other purpose.

Employees are immediately enrolled in the plan and eligible to make pre-tax deferrals, subject to limits imposed under the plan and the deferral limit established annually by the IRS, and receive Company matching contributions not in excess of 4% of compensation. The Company also makes a nondiscretionary contribution for each eligible participant in an amount equal to 5% of plan compensation and 5% of plan compensation in excess of the Social Security wage base. In order to participate in the nondiscretionary contribution, an employee must: (i) be employed on the last day of the year and be credited with 1000 hours of service during the year; (ii) die or become disabled during the year; or (iii) have attained the early or normal retirement age (as defined in the plan). The Company’s costs related to the 401(k) plan, excluding employee deferrals, in 2019 , 2018 and 2017 were $16,009 , $13,477 and $11,471 , respectively. Deferred Compensation Plans and Arrangements The Company maintains two deferred compensation plans: a Deferred Stock Unit Plan and a Deferred Income Plan. Nonemployee directors may defer all or a portion of their fees and retainer; eligible officers may defer base salary and bonus subject to limits determined annually by the Company. Amounts deferred to the Deferred Stock Unit Plan are invested in units representing shares of the Company’s common stock; benefits are paid in the form of common stock, with cash distributed in lieu of fractional shares. Amounts deferred to the Deferred Income Plan are notionally invested in the discretion of each participant from among investment alternatives substantially similar to those available under the Company’s 401(k) plan. Directors and officers who participated in the predecessor to the Deferred Income Plan as of December 31, 2006, may also invest in a preferential interest rate alternative that is derived from the Moody’s Average Corporate Bond Rate. Benefits payable from the Deferred Income Plan equal the account balance of each participant. Beneficiaries of directors and officers who have continuously deferred at rates prescribed by the Company since January 1, 2005, and who die while employed by the Company or serving as a director may receive an additional preretirement death benefit from the Deferred Income Plan. In connection with its acquisition of Brand Group Holdings, Inc. and its affiliates, the Company assumed the Brand Group Holdings, Inc. Deferred Compensation Plan. Deferral elections in effect as of the time of acquisition were given effect for compensation earned during 2018; no further deferrals have been or will be made to the plan. Account balances maintained under the plan will be distributed as provided under the terms of the plan and individual participant elections. Pending distribution, balances will be notionally invested by each participant in designated investment alternatives. The Company’s Deferred Stock Unit and Deferred Income Plan are unfunded. It is anticipated that such plans will result in no additional cost to the Company because life insurance policies on the lives of participants have been purchased in amounts estimated to be sufficient to pay plan benefits. The Company is both the owner and beneficiary of the policies. A trust is maintained for the plan assumed in connection with the acquisition of Brand Group Holdings, Inc. The value of the trust is equal to the benefits payable from such plan. The trust is maintained in the form of a grantor trust, of which the Company is named as grantor and owner. The expense recorded in 2019 , 2018 and 2017 for the Company’s Deferred Stock Unit and Deferred Income Plan, including in 2019 expense for the plan assumed in connection with the acquisition of Brand Group Holdings, Inc., inclusive of deferrals, was $3,610 , $1,290 and $1,935 , respectively. In 2007, the Company assumed supplemental executive retirement plans (SERPs) in connection with the acquisition of Capital Bancorp, Inc. and its affiliates. The plans are designed to provide four officers specified annual benefits for a 15 -year period upon the attainment of a designated retirement age. Liabilities associated with the SERPs totaled $3,921 and $3,865 at December 31, 2019 and 2018 , respectively. The plans are not qualified under Section 401 of the Internal Revenue Code. Incentive Compensation Plans Under the Company’s Performance Based Rewards Plan, annual cash bonuses are paid to eligible officers and employees, subject to the attainment of designated performance criteria that may relate to the Company’s performance, the performance of an affiliate, region, division or profit center, and/or to individual or team performance. The Company annually sets minimum, target, and superior levels of performance. Minimum performance must be attained for the payment of any bonus; superior performance must be attained for maximum payouts. The expense associated with the plan for 2019 , 2018 and 2017 was $4,200 , $5,117 and $4,490 , respectively. The Company maintains a long-term equity compensation plan - the 2011 Long-Term Incentive Compensation Plan - which provides for the grant of stock options and the award of restricted stock. Options granted under the plan permit the acquisition of shares of the Company’s common stock at an exercise price equal to the fair market value of the shares on the date of grant. Options may be subject to time-based vesting or the attainment of performance criteria; all options expire ten years after the date of grant. Options that do not vest or expire unexercised are forfeited and canceled. There were no stock options granted during the years ended December 31, 2019 , 2018 or 2017 . There was no compensation expense associated with options recorded for the years ended December 31, 2019 , 2018 or 2017 . The following table summarizes information about options outstanding, exercised and forfeited as of and for the three years ended December 31, 2019 , 2018 and 2017 : Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1, 2017 185,625 $ 15.97 Granted — — Exercised (95,875 ) 16.25 Forfeited — — Outstanding at December 31, 2017 89,750 $ 15.67 3.14 $ 2,263 Exercisable at December 31, 2017 89,750 $ 15.67 3.14 $ 2,263 Granted — — Exercised (41,000 ) 15.54 Forfeited (5,000 ) 15.32 Outstanding at December 31, 2018 43,750 $ 15.84 2.63 $ 627 Exercisable at December 31, 2018 43,750 $ 15.84 2.63 $ 627 Granted — — Exercised (14,500 ) 15.79 Forfeited — — Outstanding at December 31, 2019 29,250 $ 15.86 1.94 $ 574 Exercisable at December 31, 2019 29,250 $ 15.86 1.94 $ 574 The total intrinsic value of options exercised during the three years ended December 31, 2019 , 2018 and 2017 was $290 , $1,180 and $2,487 , respectively. All options outstanding during 2019 , 2018 and 2017 were fully vested and exercisable as of December 31, 2017. The Company also awards performance-based restricted stock to executives and other officers and employees and time-based restricted stock to non-employee directors, executives, and other officers and employees. Performance-based awards are subject to the attainment of designated performance criteria during a fixed performance cycle. Performance criteria may relate to the Company’s performance measured on an absolute basis or relative to a defined peer group. Performance criteria may also relate to the performance of an affiliate, region, division or profit center of the Company or to individual performance. The Company annually sets minimum, target, and superior levels; minimum performance must be attained for the vesting of any shares; superior performance must be attained for maximum payouts. Time-based restricted stock awards relate to a fixed number of shares that vest at the end of a designated service period. The fair value of each restricted stock award is the closing price of the Company’s common stock on the business day immediately preceding the date of the award. For restricted stock awarded under the plan, the Company recorded compensation expense of $10,046 , $7,251 and $5,293 for the years ended December 31, 2019 , 2018 and 2017 , respectively. The following table summarizes the changes in restricted stock as of and for the year ended December 31, 2019 : Performance- Based Restricted Stock Weighted Average Grant-Date Fair Value Time- Based Restricted Stock Weighted Average Grant-Date Fair Value Not vested at beginning of year 41,300 $ 40.89 304,955 $ 41.82 Awarded 154,250 30.18 308,557 32.12 Vested (77,625 ) 30.18 (92,292 ) 39.90 Forfeited and cancelled (2,200 ) 30.18 (20,288 ) 38.36 Not vested at end of year 115,725 $ 34.00 500,932 $ 36.34 Unrecognized stock-based compensation expense related to restricted stock totaled $11,156 at December 31, 2019 .

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 from time to time 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, 2019 , the Company had notional amounts of $219,664 on interest rate contracts with corporate customers and $219,664 in offsetting interest rate contracts with other financial institutions to mitigate the Company’s rate exposure on its corporate customers’ contracts. In June 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 April 2018, the Company entered into an interest rate swap agreement effective June 15, 2018. Under this swap agreement, 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 agreement, which terminates in June 2028, 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 Company’s junior subordinated debentures. 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 $215,751 and $159,464 at December 31, 2019 and 2018 , 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 $414,000 and $281,343 at December 31, 2019 and 2018 , 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 2019 2018 Derivative assets: Not designated as hedging instruments: Interest rate contracts Other Assets $ 3,880 $ 2,779 Interest rate lock commitments Other Assets 4,579 3,740 Forward commitments Other Assets 39 — Totals $ 8,498 $ 6,519 Derivative liabilities: Designated as hedging instruments: Interest rate swap Other Liabilities $ 5,021 $ 2,046 Totals $ 5,021 $ 2,046 Not designated as hedging instruments: Interest rate contracts Other Liabilities $ 3,880 $ 2,779 Interest rate lock commitments Other Liabilities 3 — Forward commitments Other Liabilities 1,096 3,563 Totals $ 4,979 $ 6,342 Gains (losses) included in the Consolidated Statements of Income related to the Company’s derivative financial instruments were as follows, as of the dates presented: Year Ended December 31, 2019 2018 2017 Derivatives not designated as hedging instruments: Interest rate contracts: Included in interest income on loans $ 3,672 $ 4,137 $ 3,981 Interest rate lock commitments: Included in mortgage banking income 882 779 356 Forward commitments Included in mortgage banking income 2,506 (3,069 ) (4,489 ) Total $ 7,060 $ 1,847 $ (152 ) 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. There were no ineffective portions for the years ended December 31, 2019 , 2018 and 2017 . The impact on other comprehensive income for the years ended December 31, 2019 , 2018 , and 2017 , can be seen at Note 18, “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 as of the dates presented: Offsetting Derivative Assets Offsetting Derivative Liabilities December 31, December 31, December 31, December 31, Gross amounts recognized $ 61 $ 1,620 $ 9,974 $ 6,768 Gross amounts offset in the consolidated balance sheets — — — — Net amounts presented in the consolidated balance sheets 61 1,620 9,974 6,768 Gross amounts not offset in the consolidated balance sheets Financial instruments 61 1,620 61 1,620 Financial collateral pledged — — 8,698 2,745 Net amounts $ — $ — $ 1,215 $ 2,403

Under the guidance of ASC 740, “Income Taxes” (“ASC 740”), the Company revalued its net deferred tax assets on the date of enactment based on the reduction in the overall future tax benefit expected to be realized at the lower tax rate implemented by the new legislation. After reviewing the Company’s inventory of deferred tax assets and liabilities on the date of enactment and giving consideration to the future impact of the lower corporate tax rates and other provisions of the new legislation, the Company’s revaluation of its net deferred tax assets was $14,486 , which was included in “Income taxes” in the Consolidated Statements of Income for the year ended December 31, 2017. No further adjustments related to the Tax Act were required in 2019 or 2018. The effective tax rate was 22.30% and 22.12% for the year ended December 31, 2019 and 2018 , respectively. The Company and its subsidiaries file a consolidated U.S. federal income tax return. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service for the years ending December 31, 2016 through 2018. The Company and its subsidiaries’ state income tax returns are open to audit under the statute of limitations for the years ended December 31, 2016 through 2018. The Company acquired federal and state net operating losses as part of its previous acquisitions, with varying expiration periods. The federal and state net operating losses acquired in the Brand acquisition were $81,288 and approximately $55,067 , respectively, all created in 2018. As part of the Tax Act and corresponding state tax laws, the federal net operating losses and the majority of the state net operating losses created by Brand during 2018 have an indefinite carryforward period. As of December 31, 2019 , there are federal and state net operating losses without expiration periods, related to the Brand acquisition, of $32,014 and $36,973 , respectively. The federal and state net operating losses acquired in the Heritage acquisition were $18,321 and $16,849 , respectively, of which $3,992 and $3,313 remain to be utilized as of December 31, 2019 . These losses begin to expire in 2029 and are expected to be fully utilized. Because the benefits are expected to be fully realized, the Company recorded no valuation allowance against the net operating losses for the year end December 31, 2019 . The table below presents the breakout of net operating losses as of the dates presented.

Fair Value Measurements

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 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 : 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 in 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, 2019 Financial assets: Securities available for sale: Trust preferred securities $ — $ — $ 9,986 $ 9,986 Other available for sale securities — 1,280,627 — 1,280,627 Total securities available for sale — 1,280,627 9,986 1,290,613 Derivative instruments — 8,498 — 8,498 Mortgage loans held for sale in loans held for sale — 318,272 — 318,272 Total financial assets $ — $ 1,607,397 $ 9,986 $ 1,617,383 Financial liabilities: Derivative instruments $ — $ 10,000 $ — $ 10,000 Level 1 Level 2 Level 3 Totals December 31, 2018 Financial assets: Securities available for sale: Trust preferred securities $ — $ — $ 10,633 $ 10,633 Other available for sale securities — 1,240,144 — 1,240,144 Total securities available for sale — 1,240,144 10,633 1,250,777 Derivative instruments — 6,519 — 6,519 Mortgage loans held for sale in loans held for sale — 219,848 — 219,848 Total financial assets $ — $ 1,466,511 $ 10,633 $ 1,477,144 Financial liabilities: Derivative instruments $ — $ 8,388 $ — $ 8,388 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 table provides for the periods presented 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 Balance at January 1, 2018 $ 9,388 Realized (gains) losses included in net income, net of premium amortization 34 Unrealized gains included in other comprehensive income 1,328 Settlements (117 ) Balance at December 31, 2018 $ 10,633 Accretion included in net income 34 Unrealized losses included in other comprehensive income (442 ) Settlements (239 ) Balance at December 31, 2019 $ 9,986 For 2019 and 2018 , 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, 2019 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 $ 9,986 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 as of the dates presented the fair value measurement for assets measured at fair value on a nonrecurring basis that were still held on the Consolidated Balance Sheets at period end and the level within the fair value hierarchy each is classified: Level 1 Level 2 Level 3 Totals December 31, 2019 Impaired loans $ — $ — $ 27,348 $ 27,348 OREO — — 2,820 2,820 Mortgage servicing rights — — 53,208 53,208 Total $ — $ — $ 83,376 $ 83,376 Level 1 Level 2 Level 3 Totals December 31, 2018 Impaired loans $ — $ — $ 21,686 $ 21,686 OREO — — 4,319 4,319 Total $ — $ — $ 26,005 $ 26,005 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 that were measured or re-measured at fair value had a carrying value of $29,606 and $22,621 at December 31, 2019 and December 31, 2018 , respectively, and a reserve for these loans of $2,258 and $935 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 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, as of the dates presented, OREO measured at fair value on a nonrecurring basis that was still held in the Consolidated Balance Sheets at period-end: December 31, 2019 December 31, 2018 Carrying amount prior to remeasurement $ 3,726 $ 5,258 Impairment recognized in results of operations (906 ) (939 ) Fair value $ 2,820 $ 4,319 Mortgage servicing rights : The Company retains the right to service certain mortgage loans that it sells to secondary market investors. Mortgage 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, 2019 and December 31, 2018 . There were $1,836 of valuation adjustments on MSRs during the twelve months ended December 31, 2019 and no valuation adjustments were recognized during the twelve months ended December 31, 2018 . The following table presents information as of December 31, 2019 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 $ 27,348 Appraised value of collateral less estimated costs to sell Estimated costs to sell 4-10% OREO $ 2,820 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 gains of $1,286 resulting from fair value changes of these mortgage loans were recorded in income during 2019 , as compared to net gains of $4,892 in 2018 and net gains of $1,594 in 2017 . The amounts do 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, 2019 : Aggregate Fair Value Aggregate Unpaid Principal Balance Difference Mortgage loans held for sale $ 318,272 $ 308,160 $ 10,112 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, 2019 Financial assets Cash and cash equivalents $ 414,930 $ 414,930 $ — $ — $ 414,930 Securities available for sale 1,290,613 — 1,280,627 9,986 1,290,613 Loans held for sale 318,272 — 318,272 — 318,272 Loans, net 9,637,476 — — 9,321,039 9,321,039 Mortgage servicing rights 53,208 — — 53,208 53,208 Derivative instruments 8,498 — 8,498 — 8,498 Financial liabilities Deposits $ 10,213,168 $ 8,052,536 $ 2,158,431 $ — $ 10,210,967 Short-term borrowings 489,091 489,091 — — 489,091 Federal Home Loan Bank advances 152,337 — 152,321 — 152,321 Junior subordinated debentures 110,215 — 104,480 — 104,480 Subordinated notes 113,955 — 117,963 — 117,963 Derivative instruments 10,000 — 10,000 — 10,000 Fair Value Carrying Value Level 1 Level 2 Level 3 Total December 31, 2018 Financial assets Cash and cash equivalents $ 569,111 $ 569,111 $ — $ — $ 569,111 Securities available for sale 1,250,777 — 1,240,144 10,633 1,250,777 Loans held for sale 411,427 — 219,848 191,579 411,427 Loans, net 9,034,103 — — 8,818,039 8,818,039 Mortgage servicing rights 48,230 — — 61,111 61,111 Derivative instruments 6,519 — 6,519 — 6,519 Financial liabilities Deposits $ 10,128,557 $ 7,765,773 $ 2,337,334 $ — $ 10,103,107 Short-term borrowings 387,706 387,706 — — 387,706 Other long-term borrowings 53 53 — — 53 Federal Home Loan Bank advances 6,690 — 6,751 — 6,751 Junior subordinated debentures 109,636 — 109,766 — 109,766 Subordinated notes 147,239 — 148,875 — 148,875 Derivative instruments 8,388 — 8,388 — 8,388

Earnings Per Share [Abstract]
Net Income Per Common Share	Net Income Per Common Share (In Thousands, Except Share Data) 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 of shares outstanding, assuming outstanding stock options were exercised into common shares and nonvested restricted stock awards, whose vesting is subject to future service requirements, were outstanding common shares as of the awards’ respective grant dates, calculated in accordance with the treasury method. Basic and diluted net income per common share calculations are as follows for the periods presented: Year Ended December 31, 2019 2018 2017 Basic Net income applicable to common stock $ 167,596 $ 146,920 $ 92,188 Average common shares outstanding 58,046,716 52,492,104 46,874,502 Net income per common share—basic $ 2.89 $ 2.80 $ 1.97 Diluted Net income applicable to common stock $ 167,596 $ 146,920 $ 92,188 Average common shares outstanding 58,046,716 52,492,104 46,874,502 Effect of dilutive stock-based compensation 179,970 134,746 127,014 Average common shares outstanding—diluted 58,226,686 52,626,850 47,001,516 Net income per common share—diluted $ 2.88 $ 2.79 $ 1.96 Outstanding stock-based compensation awards that could potentially dilute basic net income per common share in the future that were not included in the computation of diluted net income per common share due to their anti-dilutive effect were as follows for the periods presented: Year Ended December 31, 2019 2018 2017 Number of shares 643 73,257 77,545 Range of exercise prices (for stock option awards) — — —

Commitments and Contingencies Disclosure [Abstract]
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, 2019 were $2,324,262 and $94,824 , respectively, compared to $2,068,749 and $104,664 , respectively, at December 31, 2018 . 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.

Regulated Operations [Abstract]
Restrictions on Cash, Securities, Bank Dividends, Loans or Advances	Restrictions on Cash, Securities, Bank Dividends, Loans or Advances (In Thousands) Renasant Bank is required to maintain minimum average balances with the Federal Reserve. At December 31, 2019 and 2018 , Renasant Bank’s reserve requirements with the Federal Reserve were $187,839 and $113,341 , respectively, with which it was in full compliance. The Company’s balance of FHLB stock, which is carried at amortized cost, at December 31, 2019 and 2018 , was $31,092 and $19,777 , respectively. The required investment for the same time period was $31,092 and $7,471 , respectively. 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 (the “DBCF”). In addition, the FDIC has the authority to prohibit the Bank from engaging in business practices that the FDIC considers to be unsafe or unsound, which, depending on the financial condition of the Bank, could include the payment of dividends. Accordingly, the approval of the DBCF is required prior to Renasant Bank paying dividends to the Company, and under certain circumstances the approval of the FDIC may be required. At December 31, 2019 , the Bank’s earned surplus exceeded the Bank’s capital stock by more than ten times. 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, 2019 , the maximum amount available for transfer from Renasant Bank to the Company in the form of loans was $138,862 . As of December 31, 2019 , no

Regulatory Matters

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters (In Thousands) The Company and the Bank are 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 the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. 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 bank holding companies and banks must maintain. Those guidelines specify capital tiers, which include the following classifications: Capital Tiers Tier 1 Capital to Common Equity Tier 1 to Tier 1 Capital to Total Capital to 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: 2019 2018 Amount Ratio Amount Ratio Renasant Corporation Tier 1 Capital to Average Assets (Leverage) $ 1,262,588 10.37 % $ 1,188,412 10.11 % Common Equity Tier 1 Capital to Risk-Weighted Assets 1,156,828 11.12 % 1,085,751 11.05 % Tier 1 Capital to Risk-Weighted Assets 1,262,588 12.14 % 1,188,412 12.10 % Total Capital to Risk-Weighted Assets 1,432,949 13.78 % 1,386,507 14.12 % Renasant Bank Tier 1 Capital to Average Assets (Leverage) $ 1,331,809 10.95 % $ 1,276,976 10.88 % Common Equity Tier 1 Capital to Risk-Weighted Assets 1,331,809 12.81 % 1,276,976 13.02 % Tier 1 Capital to Risk-Weighted Assets 1,331,809 12.81 % 1,276,976 13.02 % Total Capital to Risk-Weighted Assets 1,388,553 13.36 % 1,331,619 13.58 % Common equity Tier 1 capital (“CET1”) generally consists of common stock, retained earnings, accumulated other comprehensive income and certain minority interests, less certain adjustments and deductions. In addition, the Company must maintain a “capital conservation buffer,” which is a specified amount of CET1 capital in addition to the amount necessary to meet minimum risk-based capital requirements. The capital conservation buffer is designed to absorb losses during periods of economic stress. If the Company’s ratio of CET1 to risk-weighted capital is below the capital conservation buffer, the Company will face restrictions on its ability to pay dividends, repurchase outstanding stock and make certain discretionary bonus payments. The required capital conservation buffer is 2.5% of CET1 to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements.

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-size businesses including checking and savings accounts, business and personal loans, asset-based lending and equipment leasing, as well as safe deposit and night depository facilities. • The Insurance segment includes a full service insurance agency offering all major lines of commercial and personal insurance through major carriers. • The Wealth Management segment offers a broad range of fiduciary services which include the administration and management of trust accounts including personal and corporate benefit accounts, self-directed IRAs, 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.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
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. Through its subsidiaries, the Company offers a diversified range of financial, wealth management, fiduciary and insurance services to its retail and commercial customers from full service offices located throughout north and central Mississippi, Tennessee, Alabama, 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 (“GAAP”) 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 : 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. Reclassifications had no effect on prior years’ net income or shareholders’ equity.
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. Presently, the Company has no intention of establishing a trading classification. Securities not classified as held to maturity or trading are classified as available for sale. 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, regardless of classification, is adjusted for amortization of premiums and accretion of discounts. Such amortization and accretion is included in interest income from securities, as is dividend income. Realized gains and losses on sales of securities are reflected under the line item “Net gains (losses) 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 Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic (“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. Recognition of investment interest is discontinued on debt securities that are transferred to nonaccrual status. 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 nonaccrual investment securities is accounted for on the cash-basis method until the debt security qualifies for return to accrual status. See Note 3, “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	Loans Held for Sale : Residential mortgage loans held for sale are included in the line item “Loans held for sale” on the Company’s Consolidated Balance Sheets. The Company has elected to carry these loans at fair value as permitted under the guidance in ASC 825, “Financial Instruments” (“ASC 825”). 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 Losse s: 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, any deferred fees or costs on originated loans and any purchase discounts or premiums on purchased 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. 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 and industrial 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, as applicable, 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. 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
Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets	Business Combinations, Accounting for Credit-Deteriorated Purchased Loans and Related Assets : Business combinations are accounted for by applying the acquisition method in accordance with ASC 805, “Business Combinations.” 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 purchased 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. Purchased credit deteriorated loans are accounted for 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.
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, three to 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. Effective January 1, 2019, ASC 842, “Leases” requires a lessee to recognize a right-of-use asset and a lease liability for all leases with a term greater than twelve months on its balance sheet regardless of the whether the lease is classified as financing or operating. All of the Company’s lessee arrangements are operating leases, being real estate leases for Company facilities. Under these arrangements, the Company records right-of-use assets and corresponding lease liabilities, each of which is based on the present value of the remaining lease payments and are discounted at the Company’s incremental borrowing rate. Right-of-use assets are reported in premises and equipment on the Consolidated Balance Sheets and the related lease liabilities are reported in other liabilities. All leases are recorded on the Consolidated Balance Sheets except for leases with an initial term less than 12 months for which the Company elected the short-term lease recognition exemption. Lease terms may contain renewal and extension options and early termination features. Many leases include one or more options to renew, with renewal terms that can extend the lease term from one to 20 years or more. The exercise of lease renewal options is at the Company’s sole discretion. Renewal options which are reasonably certain to be exercised in the future were included in the measurement of right-of-use assets and lease liabilities. Lease expense is recognized on a straight-line basis over the lease term and is recorded in occupancy and equipment expense in the Consolidated Statements of Income. Variable lease payments consist primarily of common area maintenance and taxes. The Company does not have any material sublease agreements currently in place.
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” on 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 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, mortgage interest rates and other factors. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is recognized through a valuation allowance, to the extent that unamortized cost exceeds fair value. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the valuation allowance may be recorded as an increase to income. Changes in valuation allowances related to servicing rights are reported in the line item “Mortgage banking income” on the Consolidated Statements of Income. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets
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. In connection with the acquisition of Brand (as defined below in Note 2, “Mergers and Acquisitions”), the Company acquired BOLI with a cash surrender value of $40,081 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.
Revenue from Contracts with Customers	Revenue from Contracts with Customers : ASC 606, “Revenue from Contracts with Customers,” provides guidance on revenue recognition from contracts with customers. For revenue streams within its scope, ASC 606 requires costs that are incremental to obtaining a contract to be capitalized. In the case of the Company, these costs include sales commissions for insurance and wealth management products. ASC 606 has established, and the Company has utilized, a practical expedient allowing costs that, if capitalized, would have an amortization period of one year or less to instead be expensed as incurred. Service Charges on Deposit Accounts Service charges on deposit accounts include maintenance fees on accounts, per item charges, account enhancement charges for additional packaged benefits and overdraft fees. The contracts with deposit account customers are day-to-day contracts and are considered to be terminable at will by either party. Therefore, the fees are all considered to be earned when charged and simultaneously collected. Fees and Commissions Fees and commissions include fees related to deposit services, such as ATM fees and interchange fees on debit card transactions. These fees are earned at the point in time when the services are rendered, and therefore the related revenue is recognized as the Company’s performance obligation is satisfied. Insurance Commissions Insurance commissions are earned when policies are placed by customers with the insurance carriers and are collected and recognized using two different methods: the agency bill method and the direct bill method. Under the agency bill method, Renasant Insurance is responsible for billing the customers directly and then collecting and remitting the premiums to the insurance carriers. Agency bill revenue is recognized at the later of the invoice date or effective date of the policy. The Company has established a reserve for such policies which is derived from historical collection experience and updated annually. The contract balances (i.e. accounts receivable and accounts payable related to insurance commissions earned and premiums due) and the reserve established are considered inconsequential to the overall financial results of the Company. Under the direct bill method, premium billing and collections are handled by the insurance carriers, and a commission is then paid to Renasant Insurance. Direct bill revenue is recognized when the cash is received from the insurance carriers. While there is recourse on these commissions in the event of policy cancellations, based on the Company’s historical data, significant or material reversals of revenue based on policy cancellations are not anticipated. The Company monitors policy cancellations on a monthly basis and, if a significant or material set of transactions were to occur, the Company would adjust earnings accordingly. The Company also earns contingency income that it recognizes on a cash basis. Contingency income is a bonus received from the insurance underwriters and is based on commission income and claims experience on the Company’s clients’ policies during the previous year. Increases and decreases in contingency income are reflective of corresponding increases and decreases in the amount of claims paid by insurance carriers. Wealth Management Revenue Fees for managing trust accounts (inclusive of personal and corporate benefit accounts, self-directed IRAs, and custodial accounts) are based on the value of assets under management in the account, with the amount of the fee depending on the type of account. Revenue is recognized on a monthly basis, and there is little to no risk of a material reversal of revenue. Fees for other wealth management services, such as investment guidance relating to fixed and variable annuities, mutual funds, stocks and other investments, are recognized based on either trade activity, which are recognized at the time of the trade, or assets under management, which are recognized monthly. Sales of Other Real Estate Owned The Company continually markets the properties included in the OREO portfolio. The Company will at times, in the ordinary course of business, provide seller-financing on sales of OREO. In cases where a sale is seller-financed, the Company must ensure the commitment of both parties to perform their respective obligations and the collectability of the transaction price in order to properly recognize the revenue on the sale of OREO. This is accomplished through the Company’s loan underwriting process. In this process the Company considers things such as the buyer’s initial equity in the property, the credit quality of the buyer, the financing terms of the loan and the cash flow from the property, if applicable. If it is determined that the contract criteria in ASC 606 have been met, the revenue on the sale of OREO will be recognized on the closing date of the sale when the Company has transferred title to the buyer and obtained the right to receive payment for the property. In instances where sales are not seller-financed, the Company recognizes revenue on the closing date of the sale when the Company has obtained payment for the property and transferred title to the buyer. For additional information on OREO, please see Note 8, “Other Real Estate Owned.”
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,” 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 17, “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 45 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. These types of 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
Stock-Based Compensation	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 of shares outstanding, assuming outstanding stock options were exercised into common shares and nonvested restricted stock awards, whose vesting is subject to future service requirements, were outstanding common shares as of the awards’ respective grant dates, calculated in accordance with the treasury method. See Note 20, “Net Income Per Common Share,” for the reconciliation of the numerators and denominators of the basic and diluted earnings per share computations.
Subsequent Events	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, 2019 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	Impact of Recently-Issued Accounting Standards and Pronouncements : Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842)” and its related amendments (“ASC 842”), which changed the accounting model and disclosure requirements for leases. The former accounting model for leases distinguished between capital leases, which were recognized on the balance sheet, and operating leases, which were not. Under the new standard, the lease classifications are defined as finance leases, which are similar to capital leases under prior GAAP, and operating leases. Further, under the new standard a lessee recognizes 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. The accounting model and disclosure requirements for lessors remains substantially unchanged from prior GAAP. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company chose to use the effective date approach and, as such, all periods after January 1, 2019 are presented in accordance with ASC 842 whereas periods prior to January 1, 2019 are presented in accordance with prior lease accounting. Financial information was not updated, and the disclosures required under ASC 842 were not provided for dates and periods before January 1, 2019. ASC 842 provides for a number of optional practical expedients, of which the Company has elected several including (i) the option not to separate the lease and non-lease components; (ii) the “package of practical expedients,” where the Company does not have to reassess (A) whether expired or existing contracts contain leases under the new definition of a lease, (B) lease classification for expired or existing leases and (C) whether previously capitalized initial direct costs would qualify for capitalization under ASC 842; and (iii) the use of hindsight in determining the lease term, which permits the use of information available after lease inception to determine the lease term via the knowledge of renewal options exercised but not available at the lease’s inception. Upon adoption, the Company recorded a right-of-use asset in the amount of $53,042 and a corresponding lease liability in the amount of $56,562 on January 1, 2019. The Company has included newly applicable lease disclosures in Note 26, “Leases.” In June 2016, FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). This update significantly changes the way entities recognize impairment on many financial assets by requiring immediate recognition of estimated credit losses expected to occur over the asset’s remaining life. FASB describes this impairment recognition 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 scope of FASB’s CECL model includes loans, held-to-maturity debt instruments, lease receivables, loan commitments and financial guarantees that are not accounted for at fair value. Additionally, ASU 2016-13 amends the accounting for credit losses on available for sale securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Over the course of 2019, FASB issued a number of updates clarifying various matters arising under ASU 2016-13, including the following: (1) ASU 2018-19 was issued to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20; instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases; (2) ASU 2019-04 was issued and provides entities alternatives for measurement of accrued interest receivable, clarifies the steps entities should take when recording the transfer of loans or debt securities between measurement classifications or categories and clarifies that entities should include expected recoveries on financial assets; (3) ASU 2019-05 was issued to provide entities that have certain instruments within the scope of Subtopic 320-20 with an option to irrevocably elect the fair value option in Subtopic 825-10; and (4) ASU 2019-11 was issued to clarify and address stakeholders' specific issues relating to expected recoveries on purchased credit deteriorated assets and transition and disclosure relief related to troubled debt restructured loans and accrued interest, respectively. Early adoption is permitted. The Company has developed a CECL allowance model which calculates reserves over the life of the loan and is largely driven by portfolio characteristics, risk-grading, economic outlook, and other key methodology assumptions. Those assumptions are based upon the existing probability of default and loss given default framework. The Company currently expects an increase of $35,000 to $45,000 in the allowance for credit losses and an increase of $10,000 to $15,000 in the reserve for unfunded commitments. The Company's CECL committee will periodically refine the model as needed. The Company is in the process of finalizing the review of the most recent model run and finalizing assumptions including qualitative adjustments and economic forecasts. As the Company is currently working to finalize the CECL model and the controls and processes around the model, the overall increases discussed above could differ from the numbers disclosed. Once final, the Company will record a one-time cumulative-effect adjustment to our allowance. In January 2017, FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350)” (“ASU 2017-04”). ASU 2017-04 amends and simplifies current goodwill impairment testing by eliminating certain testing under the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 became effective January 1, 2020 and is not expected to have a material impact on the Company’s financial statements. In March 2017, FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities” (“ASU 2017-08”). ASU 2017-08 requires the amortization period for certain callable debt securities held at a premium to be the earliest call date. ASU 2017-08 became effective January 1, 2019 and did not have a material impact on the Company’s financial statements. In August 2017, FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). ASU 2017-12 is intended to simplify hedge accounting by eliminating the requirement to separately measure and report hedge effectiveness. ASU 2017-12 also expands the application of hedge accounting by modifying current requirements to include hedge accounting on partial-term hedges, the hedging of prepayable financial instruments and other strategies. This update became effective January 1, 2019 and did not have a material impact on the Company’s financial statements. In August 2018, FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). ASU 2018-13 is intended to improve the disclosures on fair value measurements by eliminating, amending and adding certain disclosure requirements. These changes are intended to reduce costs for preparers while providing more useful information for financial statement users. ASU 2019-01 became effective January 1, 2020 and is not expected to have a material impact on the Company’s financial statements. In March 2019, FASB issued ASU 2019-01, “Leases (Topic 842): Codification Improvements” (“ASU 2019-01”). ASU 2019-01 is intended to clarify potential implementation questions related to ASC 842. This includes clarification on the determination of fair value of underlying assets by lessors that are not manufacturers or dealers, cash flow presentation of sales-type and direct financing leases and transition disclosures related to accounting changes and error corrections. ASU 2019-01 became effective January 1, 2020 and is not expected to have a material impact on the Company’s financial statements.
