Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition (In Thousands) The Company adopted ASU 2014-09, an update to 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 would 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 commisions 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 $31 and $79 for the three months ending June 30, 2018 and 2017, respectively, and $794 and $766 for the six months ending June 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 the 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.”
