Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (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. (“Renasant Insurance”). The Company offers a diversified range of financial, wealth management and insurance services to its retail and commercial customers through its subsidiaries and full service offices located throughout north and central Mississippi, Tennessee, Georgia, Alabama and north Florida. Basis of Presentation : The accompanying unaudited consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior year amounts have been reclassified to conform to the current year presentation. For further information regarding the Company’s significant accounting policies, refer to the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission on February 28, 2018. Business Combinations : The Company completed its acquisitions of Metropolitan BancGroup, Inc. (“Metropolitan”) and Brand Group Holdings, Inc. (“Brand”) on July 1, 2017 and September 1, 2018, respectively. The acquired institutions’ financial condition and results of operations are included in the Company’s financial condition and results of operations as of the applicable acquisition date. 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. In connection with the acquisition of Brand, the Company acquired a portfolio of non-mortgage consumer loans, which is included in the line item “Loans held for sale” on the Company’s Consolidated Balance Sheet as of September 30, 2018. The Company is currently evaluating its long-term plans with respect to this portfolio. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 850, “Business Combinations”, these loans were measured at fair value as of the acquisition date. Subsequent to the acquisition date, these loans are carried at the lower of amortized cost or fair value. Use of Estimates : The preparation of financial statements in conformity with 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, and such differences may be material. Impact of Recently-Issued Accounting Standards and Pronouncements : In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 amends the accounting model and disclosure requirements for leases. The current accounting model for leases distinguishes between capital leases, which are recognized on the balance sheet, and operating leases, which are not. Under the new standard, the lease classifications are defined as finance leases, which are similar to capital leases under current GAAP, and operating leases. Further, a lessee will recognize a lease liability and a right-of-use asset for all leases with a term greater than 12 months on its balance sheet regardless of the lease’s classification, which may significantly increase reported assets and liabilities. The accounting model and disclosure requirements for lessors remains substantially unchanged from current GAAP. ASU 2016-02 is effective for annual and interim periods in fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact ASU 2016-02 will have on its financial position and results of operations, and its financial statement disclosures, and the expected results include the recognition of leased assets and related lease liabilities on the balance sheet, along with leasehold amortization and interest expense recognized in the statements of income. 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 will significantly change 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 it 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. For public companies, this update is effective for interim and annual periods beginning after December 15, 2019. The Company has formed an implementation committee comprised of both accounting and credit employees to guide Renasant Bank through the implementation of ASU 2016-13. Currently, this committee is working with a consulting firm to develop the Company’s CECL model, which includes reviewing the different model requirements and ensuring historical data integrity across all reporting systems. In January 2017, FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350)” (“ASU 2017-04”). ASU 2017-04 will amend and simplify 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 quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 will be effective for interim and annual periods beginning after December 15, 2019 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 will be effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect that ASU 2017-08 will have on its financial position and results of operations and its financial statement disclosures. 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 seeks to expand 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. ASU 2017-12 will be effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect that ASU 2017-12 will have on its financial position and results of operations and its financial statement disclosures. 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 2018-13 will be effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect that ASU 2018-13 will have on its financial position and results of operations and its financial statement disclosures.

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 before the security’s maturity. The Company does not intend to sell any securities in an unrealized loss position that it holds, and it is not more likely than not that the Company will be required to sell any such security prior to the recovery of its amortized cost basis, which may be at maturity. 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 OTTI for the nine months ended September 30, 2018 or 2017 . The Company holds investments in pooled trust preferred securities that had an amortized cost basis of $12,351 and $12,442 and a fair value of $10,304 and $9,388 at September 30, 2018 and December 31, 2017 , respectively. At September 30, 2018 , the investments in pooled trust preferred securities consisted of two securities representing interests in various tranches of trusts collateralized by debt issued by over 160 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 September 30, 2018 , management did not, and does not currently, believe such securities will be settled at a price less than the amortized cost of the investment, but the Company previously concluded that it was probable that there had been an adverse change in estimated cash flows for both trust preferred securities and recognized credit related impairment losses on these securities in 2011. No additional impairment was recognized during the nine months ended September 30, 2018 . The following table provides information regarding the Company’s investments in pooled trust preferred securities at September 30, 2018 : Name Single/ Pooled Class/ Tranche Amortized Cost Fair Value Unrealized Loss Lowest Credit Rating Issuers Currently in Deferral or Default XXIII Pooled B-2 $ 8,283 $ 6,689 $ (1,594 ) BB 16 % XXVI Pooled B-2 4,068 3,615 (453 ) B 19 % $ 12,351 $ 10,304 $ (2,047 ) The following table provides a summary of the cumulative credit related losses recognized in earnings for which a portion of OTTI has been recognized in other comprehensive income: 2018 2017 Balance at January 1 $ (261 ) $ (3,337 ) Additions related to credit losses for which OTTI was not previously recognized — — Increases in credit loss for which OTTI was previously recognized — — Reductions for securities sold during the period — 3,076 Balance at September 30 $ (261 ) $ (261 )

Non Purchased Loans	Non Purchased Loans (In Thousands, Except Number of Loans) For purposes of this Note 4, all references to “loans” mean non purchased loans. The following is a summary of non purchased loans and leases as of the dates presented: September 30, December 31, 2017 Commercial, financial, agricultural $ 817,799 $ 763,823 Lease financing 57,576 57,354 Real estate – construction 624,892 547,658 Real estate – 1-4 family mortgage 2,000,770 1,729,534 Real estate – commercial mortgage 2,609,510 2,390,076 Installment loans to individuals 102,995 103,452 Gross loans 6,213,542 5,591,897 Unearned income (3,304 ) (3,341 ) Loans, net of unearned income $ 6,210,238 $ 5,588,556 Past Due and Nonaccrual Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, the recognition of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer and other retail loans are typically charged-off no later than the time the loan is 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Loans may be placed on nonaccrual status 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 status 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 status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table provides an aging of past due and nonaccrual loans, segregated by class, as of the dates presented: Accruing Loans Nonaccruing Loans 30-89 Days Past Due 90 Days or More Past Due Current Loans Total Loans 30-89 Days Past Due 90 Days or More Past Due Current Loans Total Loans Total Loans September 30, 2018 Commercial, financial, agricultural $ 1,606 $ 319 $ 814,246 $ 816,171 $ — $ 1,423 $ 205 $ 1,628 $ 817,799 Lease financing 320 — 57,256 57,576 — — — — 57,576 Real estate – construction 1,069 — 623,823 624,892 — — — — 624,892 Real estate – 1-4 family mortgage 7,928 2,965 1,986,079 1,996,972 207 2,678 913 3,798 2,000,770 Real estate – commercial mortgage 3,080 480 2,601,728 2,605,288 324 2,328 1,570 4,222 2,609,510 Installment loans to individuals 860 42 102,045 102,947 6 38 4 48 102,995 Unearned income — — (3,304 ) (3,304 ) — — — — (3,304 ) Total $ 14,863 $ 3,806 $ 6,181,873 $ 6,200,542 $ 537 $ 6,467 $ 2,692 $ 9,696 $ 6,210,238 December 31, 2017 Commercial, financial, agricultural $ 2,722 $ 22 $ 759,143 $ 761,887 $ 205 $ 1,033 $ 698 $ 1,936 $ 763,823 Lease financing 47 — 57,148 57,195 — 159 — 159 57,354 Real estate – construction 50 — 547,608 547,658 — — — — 547,658 Real estate – 1-4 family mortgage 11,810 2,194 1,712,982 1,726,986 — 1,818 730 2,548 1,729,534 Real estate – commercial mortgage 1,921 727 2,381,871 2,384,519 — 2,877 2,680 5,557 2,390,076 Installment loans to individuals 429 72 102,901 103,402 1 28 21 50 103,452 Unearned income — — (3,341 ) (3,341 ) — — — — (3,341 ) Total $ 16,979 $ 3,015 $ 5,558,312 $ 5,578,306 $ 206 $ 5,915 $ 4,129 $ 10,250 $ 5,588,556 Impaired Loans 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, consumer and construction loans of $500 or more 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, the loan is placed on nonaccrual status and 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. Loans accounted for under FASB ASC 310-20, “Nonrefundable Fees and Other Cost” (“ASC 310-20”), and which are impaired loans recognized in conformity with ASC 310, “Receivables” (“ASC 310”), segregated by class, were as follows as of the dates presented: Unpaid Contractual Principal Balance Recorded Investment With Allowance Recorded Investment With No Allowance Total Recorded Investment Related Allowance September 30, 2018 Commercial, financial, agricultural $ 2,426 $ 1,952 $ — $ 1,952 $ 377 Lease financing — — — — — Real estate – construction 9,725 7,560 2,165 9,725 65 Real estate – 1-4 family mortgage 8,841 8,115 — 8,115 58 Real estate – commercial mortgage 8,781 4,954 1,277 6,231 611 Installment loans to individuals 119 112 — 112 1 Total $ 29,892 $ 22,693 $ 3,442 $ 26,135 $ 1,112 December 31, 2017 Commercial, financial, agricultural $ 3,043 $ 2,365 $ — $ 2,365 $ 138 Lease financing 159 159 — 159 2 Real estate – construction 578 578 — 578 4 Real estate – 1-4 family mortgage 10,018 8,169 703 8,872 561 Real estate – commercial mortgage 12,463 9,652 — 9,652 1,861 Installment loans to individuals 121 117 — 117 1 Totals $ 26,382 $ 21,040 $ 703 $ 21,743 $ 2,567 The following table presents the average recorded investment and interest income recognized on loans accounted for under ASC 310-20 and which are impaired loans for the periods presented: Three Months Ended Three Months Ended September 30, 2018 September 30, 2017 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized Commercial, financial, agricultural $ 1,979 $ 11 $ 1,960 $ 8 Lease financing — — — — Real estate – construction 9,725 42 897 33 Real estate – 1-4 family mortgage 8,136 51 8,897 71 Real estate – commercial mortgage 6,258 37 7,575 46 Installment loans to individuals 118 1 140 1 Total $ 26,216 $ 142 $ 19,469 $ 159 Nine Months Ended Nine Months Ended September 30, 2018 September 30, 2017 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized Commercial, financial, agricultural $ 2,204 $ 31 $ 2,140 $ 8 Lease financing — — — — Real estate – construction 9,621 109 861 36 Real estate – 1-4 family mortgage 8,388 174 8,944 165 Real estate – commercial mortgage 6,354 117 7,844 134 Installment loans to individuals 121 2 148 2 Total $ 26,688 $ 433 $ 19,937 $ 345 Restructured Loans Restructured loans are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition and which 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. The tables below illustrate the impact of modifications classified as restructured loans which were made during the periods presented and held on the Consolidated Balance Sheets at the respective period end. There were no newly restructured loans during the three months ended September 30, 2018.

With respect to loans that were restructured during the nine months ended September 30, 2017 , $230 subsequently defaulted within twelve months of the restructuring. Restructured loans not performing in accordance with their restructured terms that are either contractually 90 days or more past due or placed on nonaccrual status are reported as nonperforming loans. There were two restructured loans in the amount of $228 contractually 90 days past due or more and still accruing at September 30, 2018 and three restructured loans in the amount of $597 contractually 90 days past due or more and still accruing at September 30, 2017 . The outstanding balance of restructured loans on nonaccrual status was $3,147 and $4,651 at September 30, 2018 and September 30, 2017 , respectively. Changes in the Company’s restructured loans are set forth in the table below: Number of Loans Recorded Investment Totals at January 1, 2018 54 $ 5,588 Additional loans with concessions 5 709 Reclassified as performing 2 154 Reductions due to: Reclassified as nonperforming (7 ) (598 ) Paid in full (8 ) (1,448 ) Principal paydowns — (165 ) Totals at September 30, 2018 46 $ 4,240 The allocated allowance for loan losses attributable to restructured loans was $33 and $98 at September 30, 2018 and September 30, 2017 , respectively. The Company had $19 in remaining availability under commitments to lend additional funds on these restructured loans at September 30, 2018 . There was no remaining availability under commitments to lend additional funds on these restructured loans at September 30, 2017 . Credit Quality For commercial and commercial real estate 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 these 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. Management has established more granular risk rating categories to better identify heightened credit risk as loans migrate downward in the risk rating system. The “Pass” grade is now 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 the 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 September 30, 2018 Commercial, financial, agricultural $ 596,176 $ 12,885 $ 4,729 $ 613,790 Real estate – construction 548,080 764 9,695 558,539 Real estate – 1-4 family mortgage 298,125 1,093 5,803 305,021 Real estate – commercial mortgage 2,200,150 52,845 22,073 2,275,068 Installment loans to individuals 570 — — 570 Total $ 3,643,101 $ 67,587 $ 42,300 $ 3,752,988 December 31, 2017 Commercial, financial, agricultural $ 554,943 $ 11,496 $ 4,402 $ 570,841 Real estate – construction 483,498 662 81 484,241 Real estate – 1-4 family mortgage 254,643 505 8,697 263,845 Real estate – commercial mortgage 1,983,750 50,428 24,241 2,058,419 Installment loans to individuals 921 — — 921 Total $ 3,277,755 $ 63,091 $ 37,421 $ 3,378,267 For portfolio balances of consumer, small balance consumer mortgage loans, such as 1-4 family mortgage loans, and certain other loans originated for other than commercial purposes, allowance factors are determined based on historical loss ratios by portfolio for the preceding eight quarters and may be adjusted by other qualitative criteria.

Purchased Loans	Non Purchased Loans (In Thousands, Except Number of Loans) For purposes of this Note 4, all references to “loans” mean non purchased loans. The following is a summary of non purchased loans and leases as of the dates presented: September 30, December 31, 2017 Commercial, financial, agricultural $ 817,799 $ 763,823 Lease financing 57,576 57,354 Real estate – construction 624,892 547,658 Real estate – 1-4 family mortgage 2,000,770 1,729,534 Real estate – commercial mortgage 2,609,510 2,390,076 Installment loans to individuals 102,995 103,452 Gross loans 6,213,542 5,591,897 Unearned income (3,304 ) (3,341 ) Loans, net of unearned income $ 6,210,238 $ 5,588,556 Past Due and Nonaccrual Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Generally, the recognition of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer and other retail loans are typically charged-off no later than the time the loan is 120 days past due. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Loans may be placed on nonaccrual status 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 status 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 status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table provides an aging of past due and nonaccrual loans, segregated by class, as of the dates presented: Accruing Loans Nonaccruing Loans 30-89 Days Past Due 90 Days or More Past Due Current Loans Total Loans 30-89 Days Past Due 90 Days or More Past Due Current Loans Total Loans Total Loans September 30, 2018 Commercial, financial, agricultural $ 1,606 $ 319 $ 814,246 $ 816,171 $ — $ 1,423 $ 205 $ 1,628 $ 817,799 Lease financing 320 — 57,256 57,576 — — — — 57,576 Real estate – construction 1,069 — 623,823 624,892 — — — — 624,892 Real estate – 1-4 family mortgage 7,928 2,965 1,986,079 1,996,972 207 2,678 913 3,798 2,000,770 Real estate – commercial mortgage 3,080 480 2,601,728 2,605,288 324 2,328 1,570 4,222 2,609,510 Installment loans to individuals 860 42 102,045 102,947 6 38 4 48 102,995 Unearned income — — (3,304 ) (3,304 ) — — — — (3,304 ) Total $ 14,863 $ 3,806 $ 6,181,873 $ 6,200,542 $ 537 $ 6,467 $ 2,692 $ 9,696 $ 6,210,238 December 31, 2017 Commercial, financial, agricultural $ 2,722 $ 22 $ 759,143 $ 761,887 $ 205 $ 1,033 $ 698 $ 1,936 $ 763,823 Lease financing 47 — 57,148 57,195 — 159 — 159 57,354 Real estate – construction 50 — 547,608 547,658 — — — — 547,658 Real estate – 1-4 family mortgage 11,810 2,194 1,712,982 1,726,986 — 1,818 730 2,548 1,729,534 Real estate – commercial mortgage 1,921 727 2,381,871 2,384,519 — 2,877 2,680 5,557 2,390,076 Installment loans to individuals 429 72 102,901 103,402 1 28 21 50 103,452 Unearned income — — (3,341 ) (3,341 ) — — — — (3,341 ) Total $ 16,979 $ 3,015 $ 5,558,312 $ 5,578,306 $ 206 $ 5,915 $ 4,129 $ 10,250 $ 5,588,556 Impaired Loans 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, consumer and construction loans of $500 or more 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, the loan is placed on nonaccrual status and 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. Loans accounted for under FASB ASC 310-20, “Nonrefundable Fees and Other Cost” (“ASC 310-20”), and which are impaired loans recognized in conformity with ASC 310, “Receivables” (“ASC 310”), segregated by class, were as follows as of the dates presented: Unpaid Contractual Principal Balance Recorded Investment With Allowance Recorded Investment With No Allowance Total Recorded Investment Related Allowance September 30, 2018 Commercial, financial, agricultural $ 2,426 $ 1,952 $ — $ 1,952 $ 377 Lease financing — — — — — Real estate – construction 9,725 7,560 2,165 9,725 65 Real estate – 1-4 family mortgage 8,841 8,115 — 8,115 58 Real estate – commercial mortgage 8,781 4,954 1,277 6,231 611 Installment loans to individuals 119 112 — 112 1 Total $ 29,892 $ 22,693 $ 3,442 $ 26,135 $ 1,112 December 31, 2017 Commercial, financial, agricultural $ 3,043 $ 2,365 $ — $ 2,365 $ 138 Lease financing 159 159 — 159 2 Real estate – construction 578 578 — 578 4 Real estate – 1-4 family mortgage 10,018 8,169 703 8,872 561 Real estate – commercial mortgage 12,463 9,652 — 9,652 1,861 Installment loans to individuals 121 117 — 117 1 Totals $ 26,382 $ 21,040 $ 703 $ 21,743 $ 2,567 The following table presents the average recorded investment and interest income recognized on loans accounted for under ASC 310-20 and which are impaired loans for the periods presented: Three Months Ended Three Months Ended September 30, 2018 September 30, 2017 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized Commercial, financial, agricultural $ 1,979 $ 11 $ 1,960 $ 8 Lease financing — — — — Real estate – construction 9,725 42 897 33 Real estate – 1-4 family mortgage 8,136 51 8,897 71 Real estate – commercial mortgage 6,258 37 7,575 46 Installment loans to individuals 118 1 140 1 Total $ 26,216 $ 142 $ 19,469 $ 159 Nine Months Ended Nine Months Ended September 30, 2018 September 30, 2017 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized Commercial, financial, agricultural $ 2,204 $ 31 $ 2,140 $ 8 Lease financing — — — — Real estate – construction 9,621 109 861 36 Real estate – 1-4 family mortgage 8,388 174 8,944 165 Real estate – commercial mortgage 6,354 117 7,844 134 Installment loans to individuals 121 2 148 2 Total $ 26,688 $ 433 $ 19,937 $ 345 Restructured Loans Restructured loans are those for which concessions have been granted to the borrower due to a deterioration of the borrower’s financial condition and which 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. The tables below illustrate the impact of modifications classified as restructured loans which were made during the periods presented and held on the Consolidated Balance Sheets at the respective period end. There were no newly restructured loans during the three months ended September 30, 2018.

With respect to loans that were restructured during the nine months ended September 30, 2017 , $230 subsequently defaulted within twelve months of the restructuring. Restructured loans not performing in accordance with their restructured terms that are either contractually 90 days or more past due or placed on nonaccrual status are reported as nonperforming loans. There were two restructured loans in the amount of $228 contractually 90 days past due or more and still accruing at September 30, 2018 and three restructured loans in the amount of $597 contractually 90 days past due or more and still accruing at September 30, 2017 . The outstanding balance of restructured loans on nonaccrual status was $3,147 and $4,651 at September 30, 2018 and September 30, 2017 , respectively. Changes in the Company’s restructured loans are set forth in the table below: Number of Loans Recorded Investment Totals at January 1, 2018 54 $ 5,588 Additional loans with concessions 5 709 Reclassified as performing 2 154 Reductions due to: Reclassified as nonperforming (7 ) (598 ) Paid in full (8 ) (1,448 ) Principal paydowns — (165 ) Totals at September 30, 2018 46 $ 4,240 The allocated allowance for loan losses attributable to restructured loans was $33 and $98 at September 30, 2018 and September 30, 2017 , respectively. The Company had $19 in remaining availability under commitments to lend additional funds on these restructured loans at September 30, 2018 . There was no remaining availability under commitments to lend additional funds on these restructured loans at September 30, 2017 . Credit Quality For commercial and commercial real estate 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 these 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. Management has established more granular risk rating categories to better identify heightened credit risk as loans migrate downward in the risk rating system. The “Pass” grade is now 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 the 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 September 30, 2018 Commercial, financial, agricultural $ 596,176 $ 12,885 $ 4,729 $ 613,790 Real estate – construction 548,080 764 9,695 558,539 Real estate – 1-4 family mortgage 298,125 1,093 5,803 305,021 Real estate – commercial mortgage 2,200,150 52,845 22,073 2,275,068 Installment loans to individuals 570 — — 570 Total $ 3,643,101 $ 67,587 $ 42,300 $ 3,752,988 December 31, 2017 Commercial, financial, agricultural $ 554,943 $ 11,496 $ 4,402 $ 570,841 Real estate – construction 483,498 662 81 484,241 Real estate – 1-4 family mortgage 254,643 505 8,697 263,845 Real estate – commercial mortgage 1,983,750 50,428 24,241 2,058,419 Installment loans to individuals 921 — — 921 Total $ 3,277,755 $ 63,091 $ 37,421 $ 3,378,267 For portfolio balances of consumer, small balance consumer mortgage loans, such as 1-4 family mortgage loans, and certain other loans originated for other than commercial purposes, allowance factors are determined based on historical loss ratios by portfolio for the preceding eight quarters and may be adjusted by other qualitative criteria.

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. 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.

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 future benefit accruals ceased as of December 31, 1996. The Company also provides retiree health benefits for certain employees who were employed by the Company and enrolled in the Company’s health plan as of December 31, 2004. To receive benefits, an eligible employee must retire from service with the Company and its affiliates between age 55 and 65 and be credited with at least 15 years of service or with 70 points, determined as the sum of age and service at retirement. The Company periodically determines the portion of the premium to be paid by each eligible retiree and the portion to be paid by the Company. Coverage ceases when an employee attains age 65 and is eligible for Medicare. The Company also provides life insurance coverage for each retiree in the face amount of $5 until age 70 . Retirees can purchase additional insurance or continue coverage beyond age 70 at their sole expense. The plan expense for the legacy Renasant defined benefit pension plan (“Pension Benefits - Renasant”) and post-retirement health and life plans (“Other Benefits”) for the periods presented was as follows: Pension Benefits Renasant Other Benefits Three Months Ended Three Months Ended September 30, September 30, 2018 2017 2018 2017 Service cost $ — $ — $ 2 $ 2 Interest cost 261 292 7 11 Expected return on plan assets (520 ) (485 ) — — Recognized actuarial loss 82 101 — 2 Net periodic benefit (return) cost $ (177 ) $ (92 ) $ 9 $ 15 Pension Benefits Renasant Other Benefits Nine Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Service cost $ — $ — $ 6 $ 6 Interest cost 783 876 23 32 Expected return on plan assets (1,558 ) (1,456 ) — — Recognized actuarial loss 246 301 — 5 Net periodic benefit (return) cost $ (529 ) $ (279 ) $ 29 $ 43 Incentive Compensation Plans In March 2011, the Company adopted a long-term equity incentive plan, which provides for the grant of stock options and the award of restricted stock. The plan replaced the long-term incentive plan adopted in 2001, which expired in October 2011. The Company issues shares of treasury stock to satisfy stock options exercised or restricted stock granted under the plan. Options granted under the plan allow participants to acquire shares of the Company’s common stock at a fixed exercise price and expire ten years after the grant date. Options vest and become exercisable in installments over a three -year period measured from the grant date. Options that have not vested are forfeited and cancelled upon the termination of a participant’s employment. There were no stock options granted during the nine months ended September 30, 2018 or 2017 . The following table summarizes the changes in stock options as of and for the nine months ended September 30, 2018 : Shares Weighted Average Exercise Price Options outstanding at beginning of period 89,750 $ 15.67 Granted — — Exercised (39,000 ) 15.47 Forfeited (5,000 ) 15.32 Options outstanding at end of period 45,750 $ 15.89 The Company awards performance-based restricted stock to executives and other officers and time-based restricted stock to directors, executives and other officers and employees under the long-term equity incentive plan. The performance-based restricted stock vests upon completion of a designated service period or the attainment of specified performance goals. Target performance levels are derived from the Company’s budget, with threshold performance set at approximately 5% below target and superior performance set at approximately 5% above target. Performance-based restricted stock is granted at the target level; the number of shares ultimately awarded is determined at the end of the applicable performance period and may be increased or decreased depending upon the Company meeting or exceeding (or failing to meet or exceed) the financial performance measures defined by the Board of Directors. Time-based restricted stock vests at the end of the service period defined in the respective grant. The fair value of each restricted stock grant is the closing price of the Company’s common stock on the day immediately preceding the grant date. The following table summarizes the changes in restricted stock as of and for the nine months ended September 30, 2018 : Performance-Based Restricted Stock Weighted Average Grant-Date Fair Value Time- Based Restricted Stock Weighted Average Grant-Date Fair Value Nonvested at beginning of period — $ — 218,075 $ 39.08 Awarded 95,183 40.89 184,340 43.10 Vested — — (75,646 ) 36.97 Cancelled (3,014 ) 40.89 (16,046 ) 41.94 Nonvested at end of period 92,169 $ 40.89 310,723 $ 41.83 During the nine months ended September 30, 2018 , the Company reissued 108,509 shares from treasury in connection with the exercise of stock options and awards of restricted stock.

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights (In Thousands) The Company retains the right to service certain mortgage loans that it sells to secondary market investors. These mortgage servicing rights (“MSRs”) are recognized as a separate asset on the date the corresponding mortgage loan is sold. MSRs are amortized in proportion to and over the period of estimated net servicing income. These servicing rights are carried at the lower of amortized cost or fair value. Fair value is determined using an income approach with various assumptions including expected cash flows, prepayment speeds, market discount rates, servicing costs, and other factors. Impairment losses on MSRs are recognized to the extent by which the unamortized cost exceeds fair value. There were no impairment losses recognized during the nine months ended September 30, 2018 and 2017 . Changes in the Company’s MSRs were as follows: Balance at January 1, 2018 $ 39,339 Capitalization 10,745 Amortization (3,671 ) Balance at September 30, 2018 $ 46,413 Data and key economic assumptions related to the Company’s MSRs are as follows as of the dates presented: September 30, 2018 December 31, 2017 September 30, 2017 Unpaid principal balance $ 4,533,400 $ 4,012,519 $ 3,703,064 Weighted-average prepayment speed (CPR) 7.46 % 8.04 % 8.89 % Estimated impact of a 10% increase $ (5,872 ) $ (1,592 ) $ (1,501 ) Estimated impact of a 20% increase (3,732 ) (3,095 ) (2,910 ) Discount rate 9.43 % 9.69 % 9.68 % Estimated impact of a 10% increase $ (2,758 ) $ (2,027 ) $ (1,711 ) Estimated impact of a 20% increase (5,291 ) (3,896 ) (3,292 ) Weighted-average coupon interest rate 4.00 % 3.89 % 3.89 % Weighted-average servicing fee (basis points) 27.02 26.36 26.22 Weighted-average remaining maturity (in years) 8.32 7.98 14.94 The Company recorded servicing fees of $2,154 and $1,461 for the three months ended September 30, 2018 and 2017 , respectively, which are included in “Mortgage banking income” in the Consolidated Statements of Income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments (In Thousands) The Company utilizes derivative financial instruments, including interest rate contracts such as swaps, caps and/or floors, as part of its ongoing efforts to mitigate its interest rate risk exposure and to facilitate the needs of its customers. The Company also 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 September 30, 2018 , the Company had notional amounts of $204,100 on interest rate contracts with corporate customers and $204,100 in offsetting interest rate contracts with other financial institutions to mitigate the Company’s rate exposure on its corporate customers’ contracts and certain fixed-rate loans. 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 each accounted for as a cash flow hedge 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 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 and adjustable-rate residential mortgage loans. The notional amount of commitments to fund fixed-rate and adjustable-rate mortgage loans was $236,932 and $131,000 at September 30, 2018 and December 31, 2017 , 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 $381,089 and $199,000 at September 30, 2018 and December 31, 2017 , respectively. The following table provides details on the Company’s derivative financial instruments as of the dates presented: Fair Value Balance Sheet Location September 30, December 31, 2017 Derivative assets: Designated as hedging instruments Interest rate swap Other Assets $ 772 $ — Totals $ 772 $ — Not designated as hedging instruments: Interest rate contracts Other Assets $ 4,370 $ 3,171 Interest rate lock commitments Other Assets 4,309 2,756 Forward commitments Other Assets 1,665 50 Totals $ 10,344 $ 5,977 Derivative liabilities: Designated as hedging instruments: Interest rate swaps Other Liabilities $ 781 $ 2,536 Totals $ 781 $ 2,536 Not designated as hedging instruments: Interest rate contracts Other Liabilities $ 4,370 $ 3,171 Interest rate lock commitments Other Liabilities 83 4 Forward commitments Other Liabilities 79 328 Totals $ 4,532 $ 3,503 Gains (losses) included in the Consolidated Statements of Income related to the Company’s derivative financial instruments were as follows as of the periods presented: Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Derivatives not designated as hedging instruments: Interest rate contracts: Included in interest income on loans $ 1,042 $ 1,652 $ 3,066 $ 3,021 Interest rate lock commitments: Included in mortgage banking income (1,737 ) (441 ) 209 874 Forward commitments Included in mortgage banking income 2,839 (486 ) 1,915 (4,099 ) Total $ 2,144 $ 725 $ 5,190 $ (204 ) 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 nine months ended September 30, 2018 or 2017 . The impact on other comprehensive income for the nine months ended September 30, 2018 and 2017 , respectively, can be seen at Note 15, “Other Comprehensive Income (Loss).” Offsetting Certain financial instruments, including derivatives, may be eligible for offset in the consolidated balance sheet when the “right of offset” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements; however, the Company has not elected to offset such financial instruments in the Consolidated Balance Sheets. The following table presents the Company’s gross derivative positions as recognized in the Consolidated Balance Sheets as well as the net derivative positions, including collateral pledged to the extent the application of such collateral did not reduce the net derivative liability position below zero, had the Company elected to offset those instruments subject to an enforceable master netting agreement: Offsetting Derivative Assets Offsetting Derivative Liabilities September 30, December 31, 2017 September 30, December 31, 2017 Gross amounts recognized $ 6,168 $ 717 $ 1,334 $ 5,303 Gross amounts offset in the Consolidated Balance Sheets — — — — Net amounts presented in the Consolidated Balance Sheets 6,168 717 1,334 5,303 Gross amounts not offset in the Consolidated Balance Sheets Financial instruments 553 717 553 717 Financial collateral pledged — — 781 4,357 Net amounts $ 5,615 $ — $ — $ 229

As a result, the Company calculated taxes during 2018 based on a 21% federal corporate tax rate, whereas taxes were calculated in previous periods based on a 35% federal corporate tax rate. 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 as a reduction in “Income taxes” in the Consolidated Statements of Income for the year ended December 31, 2017. Although in the normal course of business the Company is required to make estimates and assumptions for certain tax items which cannot be fully determined at period end, the Company did not identify items for which the income tax effects of the Tax Act had not been completed as of December 31, 2017 and, therefore, considered its accounting for the tax effects of the Tax Act on its deferred tax assets and liabilities to have been completed as of December 31, 2017. The Company acquired both federal and state net operating losses as part of the acquisition of Brand. The federal net operating losses are approximately $82,450 . While the state net operating losses are still being evaluated, they are estimated to be approximately $65,347 . The Company expects to utilize its federal and state net operating losses, including net operating losses acquired in previous acquisitions, before expiration. Because the benefits are expected to be fully realized, the Company recorded no valuation allowance against the net operating losses for the nine months ended September 30, 2018 or 2017 or the year ended December 31, 2017 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements (In Thousands) Fair Value Measurements and the Fair Level Hierarchy 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). 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 on a recurring basis 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, “Financial Instruments” (“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, obligations of states and political subdivisions, 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 : The Company uses derivatives to manage various financial risks. Most of the Company’s derivative contracts are extensively 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 such as 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 September 30, 2018 Financial assets: Securities available for sale: Obligations of other U.S. Government agencies and corporations $ — $ 3,506 $ — $ 3,506 Obligations of states and political subdivisions — 210,319 — 210,319 Residential mortgage-backed securities: Government agency mortgage backed securities — 560,587 — 560,587 Government agency collateralized mortgage obligations — 307,228 — 307,228 Commercial mortgage-backed securities: Government agency mortgage backed securities — 21,735 — 21,735 Government agency collateralized mortgage obligations — 28,962 — 28,962 Trust preferred securities — — 10,304 10,304 Other debt securities — 34,965 — 34,965 Total securities available for sale — 1,167,302 10,304 1,177,606 Derivative instruments: Interest rate swaps — 772 — 772 Interest rate contracts — 4,370 — 4,370 Interest rate lock commitments — 4,309 — 4,309 Forward commitments — 1,665 — 1,665 Total derivative instruments — 11,116 — 11,116 Mortgage loans held for sale in loans held for sale — 252,025 — 252,025 Total financial assets $ — $ 1,430,443 $ 10,304 $ 1,440,747 Financial liabilities: Derivative instruments: Interest rate swaps $ — $ 781 $ — $ 781 Interest rate contracts — 4,370 — 4,370 Interest rate lock commitments — 83 — 83 Forward commitments — 79 — 79 Total derivative instruments — 5,313 — 5,313 Total financial liabilities $ — $ 5,313 $ — $ 5,313 Level 1 Level 2 Level 3 Totals December 31, 2017 Financial assets: Securities available for sale: Obligations of other U.S. Government agencies and corporations $ — $ 3,564 $ — $ 3,564 Obligations of states and political subdivisions — 234,481 — 234,481 Residential mortgage-backed securities: Government agency mortgage backed securities — 193,950 — 193,950 Government agency collateralized mortgage obligations — 176,639 — 176,639 Commercial mortgage-backed securities: Government agency mortgage backed securities — 31,170 — 31,170 Government agency collateralized mortgage obligations — 5,006 — 5,006 Trust preferred securities — — 9,388 9,388 Other debt securities — 17,290 — 17,290 Total securities available for sale — 662,100 9,388 671,488 Derivative instruments: Interest rate contracts — 3,171 — 3,171 Interest rate lock commitments — 2,756 — 2,756 Forward commitments — 50 — 50 Total derivative instruments — 5,977 — 5,977 Mortgage loans held for sale — 108,316 — 108,316 Total financial assets $ — $ 776,393 $ 9,388 $ 785,781 Financial liabilities: Derivative instruments: Interest rate swaps $ — $ 2,536 $ — $ 2,536 Interest rate contracts — 3,171 — 3,171 Interest rate lock commitments — 4 — 4 Forward commitments — 328 — 328 Total derivative instruments — 6,039 — 6,039 Total financial liabilities $ — $ 6,039 $ — $ 6,039 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. Transfers between levels of the hierarchy are deemed to have occurred at the end of period. There were no such transfers between levels of the fair value hierarchy during the nine months ended September 30, 2018 . The following tables provide a reconciliation for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs, or Level 3 inputs, as of the dates presented: Three Months Ended September 30, 2018 Trust preferred securities Balance at July 1, 2018 $ 10,401 Accretion included in net income 8 Unrealized gains included in other comprehensive income (45 ) Purchases — Sales — Issues — Settlements (60 ) Transfers into Level 3 — Transfers out of Level 3 — Balance at September 30, 2018 $ 10,304 Three Months Ended September 30, 2017 Trust preferred securities Balance at July 1, 2017 $ 16,992 Accretion included in net income 28 Unrealized gains included in other comprehensive income 1,307 Purchases — Sales (9,346 ) Issues — Settlements (21 ) Transfers into Level 3 — Transfers out of Level 3 — Balance at September 30, 2017 $ 8,960 Nine Months Ended September 30, 2018 Trust preferred securities Balance at January 1, 2018 $ 9,388 Accretion included in net income 25 Unrealized gains included in other comprehensive income 1,007 Purchases — Sales — Issues — Settlements (116 ) Transfers into Level 3 — Transfers out of Level 3 — Balance at September 30, 2018 $ 10,304 Nine Months Ended September 30, 2017 Trust preferred securities Balance at January 1, 2017 $ 18,389 Accretion included in net income 74 Unrealized losses included in other comprehensive income 1,866 Reclassification adjustment — Purchases — Sales (9,346 ) Issues — Settlements (2,023 ) Transfers into Level 3 — Transfers out of Level 3 — Balance at September 30, 2017 $ 8,960 For each of the three and nine months ended September 30, 2018 and 2017 , 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 September 30, 2018 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 $ 10,304 Discounted cash flows Default rate 0-100% Nonrecurring Fair Value Measurements Certain assets and liabilities may be recorded at fair value on a nonrecurring basis. These nonrecurring fair value adjustments typically are a result of the application of the lower of cost or market accounting or a write-down occurring during the period. The following table provides the fair value measurement for assets measured at fair value on a nonrecurring basis that were still held on the Consolidated Balance Sheets as of the dates presented and the level within the fair value hierarchy each is classified: September 30, 2018 Level 1 Level 2 Level 3 Totals Impaired loans $ — $ — $ 14,207 $ 14,207 OREO — — 4,162 4,162 Total $ — $ — $ 18,369 $ 18,369 December 31, 2017 Level 1 Level 2 Level 3 Totals Impaired loans $ — $ — $ 9,251 $ 9,251 OREO — — 7,392 7,392 Total $ — $ — $ 16,643 $ 16,643 The following methods and assumptions are used by the Company to estimate the fair values of the Company’s financial 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 $14,341 and $9,608 at September 30, 2018 and December 31, 2017 , respectively, and a specific reserve for these loans of $134 and $357 was included in the allowance for loan losses as of such dates. 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 OREO measured at fair value on a nonrecurring basis that was still held in the Consolidated Balance Sheets as of the dates presented: September 30, December 31, 2017 Carrying amount prior to remeasurement $ 4,989 $ 8,732 Impairment recognized in results of operations (827 ) (1,340 ) Fair value $ 4,162 $ 7,392 The following table presents information as of September 30, 2018 about significant unobservable inputs (Level 3) used in the valuation of assets and liabilities measured at fair value on a nonrecurring basis: Financial instrument Fair Value Valuation Technique Significant Unobservable Inputs Range of Inputs Impaired loans $ 14,207 Appraised value of collateral less estimated costs to sell Estimated costs to sell 4-10% OREO 4,162 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 $1,723 and $5,093 resulting from fair value changes of these mortgage loans were recorded in income during the nine months ended September 30, 2018 and 2017 , respectively. The amount does not reflect changes in fair values of related derivative instruments used to hedge exposure to market-related risks associated with these mortgage loans. The change in fair value of both mortgage loans held for sale and the related derivative instruments are recorded in “Mortgage banking income” in the Consolidated Statements of Income. The Company’s valuation of mortgage loans held for sale incorporates an assumption for credit risk; however, given the short-term period that the Company holds these loans, valuation adjustments attributable to instrument-specific credit risk is nominal. Interest income on mortgage loans held for sale measured at fair value is accrued as it is earned based on contractual rates and is reflected in loan interest income on the Consolidated Statements of Income. The following table summarizes the differences between the fair value and the principal balance for mortgage loans held for sale measured at fair value as of September 30, 2018 : Aggregate Fair Value Aggregate Unpaid Principal Balance Difference Mortgage loans held for sale measured at fair value $ 252,025 $ 246,806 $ 5,219 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 As of September 30, 2018 Carrying Value Level 1 Level 2 Level 3 Total Financial assets Cash and cash equivalents $ 369,596 $ 369,596 $ — $ — $ 369,596 Securities available for sale 1,177,606 — 1,167,302 10,304 1,177,606 Loans held for sale 463,287 — 252,025 211,262 463,287 Loans, net 9,074,297 — — 8,872,325 8,872,325 Mortgage servicing rights 46,413 — — 61,655 61,655 Derivative instruments 11,116 — 11,116 — 11,116 Financial liabilities Deposits $ 10,171,948 $ 7,768,192 $ 2,397,492 $ — $ 10,165,684 Short-term borrowings 175,559 175,559 — — 175,559 Other long-term borrowings 61 61 — — 61 Federal Home Loan Bank advances 6,887 — 6,906 — 6,906 Junior subordinated debentures 109,492 — 107,285 — 107,285 Subordinated notes 147,517 — 149,762 — 149,762 Derivative instruments 5,313 — 5,313 — 5,313 Fair Value As of December 31, 2017 Carrying Value Level 1 Level 2 Level 3 Total Financial assets Cash and cash equivalents $ 281,453 $ 281,453 $ — $ — $ 281,453 Securities available for sale 671,488 — 662,100 9,388 671,488 Loans held for sale 108,316 — 108,316 — 108,316 Loans, net 7,574,111 — — 7,514,185 7,514,185 Mortgage servicing rights 39,339 — — 47,868 47,868 Derivative instruments 5,977 — 5,977 — 5,977 Financial liabilities Deposits $ 7,921,075 $ 6,114,391 $ 1,809,085 $ — $ 7,923,476 Short-term borrowings 89,814 89,814 — — 89,814 Other long-term borrowings 98 98 — — 98 Federal Home Loan Bank advances 7,493 — 7,661 — 7,661 Junior subordinated debentures 85,881 — 69,702 — 69,702 Subordinated notes 114,074 — 118,650 — 118,650 Derivative instruments 6,039 — 6,039 — 6,039

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 service-based restricted stock awards fully vested and outstanding stock options were exercised into common shares, calculated in accordance with the treasury method. Basic and diluted net income per common share calculations are as follows for the periods presented: Three Months Ended September 30, 2018 2017 Basic Net income applicable to common stock $ 31,964 $ 26,421 Average common shares outstanding 52,472,971 49,316,572 Net income per common share - basic $ 0.61 $ 0.54 Diluted Net income applicable to common stock $ 31,964 $ 26,421 Average common shares outstanding 52,472,971 49,316,572 Effect of dilutive stock-based compensation 136,931 118,653 Average common shares outstanding - diluted 52,609,902 49,435,225 Net income per common share - diluted $ 0.61 $ 0.53 Nine Months Ended September 30, 2018 2017 Basic Net income applicable to common stock $ 102,500 $ 75,677 Average common shares outstanding 50,425,797 46,050,250 Net income per common share - basic $ 2.03 $ 1.64 Diluted Net income applicable to common stock $ 102,500 $ 75,677 Average common shares outstanding 50,425,797 46,050,250 Effect of dilutive stock-based compensation 127,395 117,891 Average common shares outstanding - diluted 50,553,192 46,168,141 Net income per common share - diluted $ 2.03 $ 1.64 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: Three Months Ended September 30, 2018 2017 Number of shares 43,779 — Exercise prices (for stock option awards) — — Nine Months Ended September 30, 2018 2017 Number of shares 73,507 — Exercise prices (for stock option awards) — —

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 Average Assets (Leverage) Common Equity Tier 1 to Risk - Weighted Assets Tier 1 Capital to Risk – Weighted Assets Total Capital to Risk – Weighted Assets Well capitalized 5% or above 6.5% or above 8% or above 10% or above Adequately capitalized 4% or above 4.5% or above 6% or above 8% or above Undercapitalized Less than 4% Less than 4.5% Less than 6% Less than 8% Significantly undercapitalized Less than 3% Less than 3% Less than 4% Less than 6% Critically undercapitalized Tangible Equity / Total Assets less than 2% The following table provides the capital and risk-based capital and leverage ratios for the Company and for Renasant Bank as of the dates presented: September 30, 2018 December 31, 2017 Amount Ratio Amount Ratio Renasant Corporation Tier 1 Capital to Average Assets (Leverage) $ 1,163,729 9.85 % $ 979,604 10.18 % Common Equity Tier 1 Capital to Risk-Weighted Assets 1,061,631 10.80 % 896,733 11.34 % Tier 1 Capital to Risk-Weighted Assets 1,163,729 11.84 % 979,604 12.39 % Total Capital to Risk-Weighted Assets 1,361,289 13.85 % 1,142,926 14.46 % Renasant Bank Tier 1 Capital to Average Assets (Leverage) $ 1,250,610 10.60 % $ 1,000,715 10.42 % Common Equity Tier 1 Capital to Risk-Weighted Assets 1,250,610 12.75 % 1,000,715 12.69 % Tier 1 Capital to Risk-Weighted Assets 1,250,610 12.75 % 1,000,715 12.69 % Total Capital to Risk-Weighted Assets 1,304,760 13.30 % 1,050,751 13.32 % 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. When fully phased in on January 1, 2019, the required capital conservation buffer will be 2.5% of CET1 to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements; as of September 30, 2018, the capital conservation buffer is 1.875% of risk-weighted assets. In addition, the Basel III regulatory capital reforms and rules effecting certain changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 issued by the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency (the “Basel III Rules”) have revised the agencies’ rules for calculating risk-weighted assets to enhance risk sensitivity and to incorporate certain international capital standards of the Basel Committee on Banking Supervision. These revisions affect the calculation of the denominator of a banking organization’s risk-based capital ratios to reflect the higher-risk nature of certain types of loans. As applicable to Renasant Bank: — For residential mortgages, the former 50% risk weight for performing residential first-lien mortgages and 100% risk-weight for all other mortgages has been replaced with a risk weight of between 35% and 200% determined by the mortgage’s loan-to-value ratio and whether the mortgage falls into one of two categories based on eight criteria that include the term, use of negative amortization and balloon payments, certain rate increases and documented and verified borrower income. — For commercial mortgages, a 150% risk weight for certain high volatility commercial real estate acquisition, development and construction loans has been substituted for the former 100% risk weight. — For nonperforming loans, the former 100% risk weight is now a 150% risk weight for loans, other than residential mortgages, that are 90 days past due or on nonaccrual status. Finally, Tier 1 capital treatment for “hybrid” capital items like trust preferred securities has been eliminated, subject to various grandfathering and transition rules.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting (In Thousands) The operations of the Company’s reportable segments are described as follows: • The Community Banks segment delivers a complete range of banking and financial services to individuals and small to medium-sized businesses including checking and savings accounts, business and personal loans, 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. The following table provides financial information for the Company’s operating segments as of and for the periods presented: Community Banks Insurance Wealth Management Other Consolidated Three months ended September 30, 2018 Net interest income (loss) $ 101,970 $ 124 $ 324 $ (2,979 ) $ 99,439 Provision for loan losses 2,250 — — — 2,250 Noninterest income 32,140 2,488 3,641 (216 ) 38,053 Noninterest expense 89,370 1,899 3,284 193 94,746 Income (loss) before income taxes 42,490 713 681 (3,388 ) 40,496 Income tax expense (benefit) 9,226 186 — (880 ) 8,532 Net income (loss) $ 33,264 $ 527 $ 681 $ (2,508 ) $ 31,964 Total assets $ 12,634,614 $ 25,236 $ 62,502 $ 24,587 $ 12,746,939 Goodwill $ 924,494 $ 2,767 — — $ 927,261 Three months ended September 30, 2017 Net interest income (loss) $ 92,007 $ 114 $ 564 $ (2,668 ) $ 90,017 Provision for loan losses 2,150 — — — 2,150 Noninterest income 28,120 2,394 3,213 (314 ) 33,413 Noninterest expense 75,681 1,805 2,887 287 80,660 Income (loss) before income taxes 42,296 703 890 (3,269 ) 40,620 Income tax expense (benefit) 15,199 275 — (1,275 ) 14,199 Net income (loss) $ 27,097 $ 428 $ 890 $ (1,994 ) $ 26,421 Total assets $ 10,216,826 $ 25,729 $ 59,703 $ 21,429 $ 10,323,687 Goodwill $ 608,279 $ 2,767 — — $ 611,046 Community Banks Insurance Wealth Management Other Consolidated Nine months ended September 30, 2018 Net interest income (loss) $ 288,073 $ 348 $ 952 $ (8,305 ) $ 281,068 Provision for loan losses 5,810 — — — 5,810 Noninterest income (loss) 90,007 7,408 10,882 (710 ) 107,587 Noninterest expense 235,631 5,449 9,889 747 251,716 Income (loss) before income taxes 136,639 2,307 1,945 (9,762 ) 131,129 Income tax expense (benefit) 30,558 599 — (2,528 ) 28,629 Net income (loss) $ 106,081 $ 1,708 $ 1,945 $ (7,234 ) $ 102,500 Total assets $ 12,634,614 $ 25,236 $ 62,502 $ 24,587 $ 12,746,939 Goodwill $ 924,494 $ 2,767 — — $ 927,261 Nine months ended September 30, 2017 Net interest income (loss) $ 249,355 $ 330 $ 1,575 $ (7,625 ) $ 243,635 Provision for loan losses 5,400 — — — 5,400 Noninterest income 83,290 7,207 9,599 (397 ) 99,699 Noninterest expense 209,920 5,263 8,788 839 224,810 Income (loss) before income taxes 117,325 2,274 2,386 (8,861 ) 113,124 Income tax expense (benefit) 40,021 888 — (3,462 ) 37,447 Net income (loss) $ 77,304 $ 1,386 $ 2,386 $ (5,399 ) $ 75,677 Total assets $ 10,216,826 $ 25,729 $ 59,703 $ 21,429 $ 10,323,687 Goodwill $ 608,279 $ 2,767 — — $ 611,046

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition (In Thousands) The Company adopted ASU 2014-09, an update to ASC 606, “Revenue from Contracts with Customers” (“ASC 606”), in the first quarter of 2018. The majority of the Company’s revenue streams are governed by other authoritative guidance and, therefore, considered out-of-scope of ASC 606. The Company’s revenue streams that are considered in-scope of ASC 606 are discussed below. 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. Insurance Commissions Through Renasant Insurance, we offer a range of commercial and personal insurance products through major insurance carriers, which include health and life insurance and property and casualty insurance. 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 occurred, the Company will 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 both 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. Contingency income, which is included in “Other noninterest income” in the Consolidated Statements of Income, was $22 and $24 for the three months ended September 30, 2018 and 2017 , respectively, and $816 and $789 for the nine months ended September 30, 2018 and 2017 , respectively. Wealth Management Revenue Wealth management consists of the Trust division and the Financial Services division. The Trust division operates on a custodial basis which includes administration of benefit plans as well as accounting and money management for trust accounts. The division manages a number of trust accounts inclusive of personal and corporate benefit accounts, self-directed IRAs, and custodial accounts. Fees for managing these 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 monthly basis, and there is little to no risk of a material reversal of revenue. The contract balance (i.e. management fee receivable) recognized is considered inconsequential to the overall financial results of the Company. The Financial Services division provides specialized products and services to the Company’s customers, which include investment guidance relating to fixed and variable annuities, mutual funds, stocks and other investments offered through a third party provider. Fees 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 borrower, 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 7, “Other Real Estate Owned.”

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events (In Thousands) On October 24, 2018, the Company’s Board of Directors authorized the repurchase of up to $50,000 of the Company’s outstanding common stock, either in open market purchases or privately-negotiated transactions. The stock repurchase program will remain in effect for one year or, if earlier, the repurchase of the entire amount of common stock authorized to be repurchased by the Board. The repurchase program had no impact on the Company’s balance sheet or results of operations for the nine months ending September 30, 2018. On October 31, 2018, the Company completed the sale of BMG, the mortgage subsidiary of Brand. The transaction did not have a material impact to the Company’s financial condition or results of operations.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
Basis of presentation	Basis of Presentation : The accompanying unaudited consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior year amounts have been reclassified to conform to the current year presentation. For further information regarding the Company’s significant accounting policies, refer to the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission on February 28, 2018.
Business combinations	Business Combinations : The Company completed its acquisitions of Metropolitan BancGroup, Inc. (“Metropolitan”) and Brand Group Holdings, Inc. (“Brand”) on July 1, 2017 and September 1, 2018, respectively. The acquired institutions’ financial condition and results of operations are included in the Company’s financial condition and results of operations as of the applicable acquisition date. 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. In connection with the acquisition of Brand, the Company acquired a portfolio of non-mortgage consumer loans, which is included in the line item “Loans held for sale” on the Company’s Consolidated Balance Sheet as of September 30, 2018. The Company is currently evaluating its long-term plans with respect to this portfolio. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 850, “Business Combinations”, these loans were measured at fair value as of the acquisition date. Subsequent to the acquisition date, these loans are carried at the lower of amortized cost or fair value.
Use of estimates	Use of Estimates : The preparation of financial statements in conformity with 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, and such differences may be material.
Impact of recently-issued accounting standards and pronouncements	Impact of Recently-Issued Accounting Standards and Pronouncements : In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 amends the accounting model and disclosure requirements for leases. The current accounting model for leases distinguishes between capital leases, which are recognized on the balance sheet, and operating leases, which are not. Under the new standard, the lease classifications are defined as finance leases, which are similar to capital leases under current GAAP, and operating leases. Further, a lessee will recognize a lease liability and a right-of-use asset for all leases with a term greater than 12 months on its balance sheet regardless of the lease’s classification, which may significantly increase reported assets and liabilities. The accounting model and disclosure requirements for lessors remains substantially unchanged from current GAAP. ASU 2016-02 is effective for annual and interim periods in fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact ASU 2016-02 will have on its financial position and results of operations, and its financial statement disclosures, and the expected results include the recognition of leased assets and related lease liabilities on the balance sheet, along with leasehold amortization and interest expense recognized in the statements of income. 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 will significantly change 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 it 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. For public companies, this update is effective for interim and annual periods beginning after December 15, 2019. The Company has formed an implementation committee comprised of both accounting and credit employees to guide Renasant Bank through the implementation of ASU 2016-13. Currently, this committee is working with a consulting firm to develop the Company’s CECL model, which includes reviewing the different model requirements and ensuring historical data integrity across all reporting systems. In January 2017, FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350)” (“ASU 2017-04”). ASU 2017-04 will amend and simplify 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 quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 will be effective for interim and annual periods beginning after December 15, 2019 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 will be effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect that ASU 2017-08 will have on its financial position and results of operations and its financial statement disclosures. 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 seeks to expand 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. ASU 2017-12 will be effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect that ASU 2017-12 will have on its financial position and results of operations and its financial statement disclosures. 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 2018-13 will be effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect that ASU 2018-13 will have on its financial position and results of operations and its financial statement disclosures.
