Revenue Recognition [Abstract]
Revenue Recognition	8. Revenue Recognition Effective January 1, 2018, the Company adopted the amended provisions of the Financial Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers,” using the modified retrospective approach. The standard applies to most of the Company’s noninterest income, with a significant portion of the Company’s revenue excluded from the scope of the standard, including interest and loan origination fees associated with financial instruments, gains and losses on investment securities, derivatives and sales of financial instruments. The Company’s evaluation of contracts for compliance with the standard did not identify any material changes to the timing of revenue recognition as the standard was largely consistent with the existing guidance and current practices. Therefore, the adoption of this guidance did not have a material impact on the Company’s financial condition or results of operations and there was no cumulative effect adjustment to opening retained earnings. However, upon adoption the Company has begun presenting certain underwriting costs (previously offset against Investment and Annuity Fees), as well as certain subadvisor costs (previously offset against Trust Fees) gross as noninterest expense, neither of which are material to operating results. Due to the nature of the Company’s primary sources of revenue, there are no significant receivables, contract assets or contract liabilities not otherwise disclosed. The Company has assessed that its current disclosures are consistent with the requirements of the standard to present revenue disaggregated in to categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The following provides additional qualitative disclosures about the Company’s noninterest income and revenue recognition policies. Service Charges on Deposit Accounts Service charges on deposit accounts include transaction based fees for non-sufficient funds, account analysis fees, and other service charges on deposits, including monthly account service fees. Non-sufficient funds fees are recognized at the time when the account overdraft occurs in accordance with regulatory guidelines. Account analysis fees consist of fees charged on certain business deposit accounts based upon account activity as well as other monthly account fees, are recorded under the accrual method of accounting as services are performed. Other service charges are earned by providing depositors safeguard and remittance of funds as well as by providing other elective services for depositors that are performed upon the depositor’s request. Charges for deposit services for the safeguard and remittance of funds are recognized at the end of the statement cycle, after services are provided, as the customer retains funds in the account. Revenue for other elective services is earned at the point in time the customer uses the service. Trust Fees Trust fee income represents revenue generated from asset management services provided to individuals, businesses, and institutions. The Company has a fiduciary responsibility to the beneficiary of the trust to perform agreed upon services which can include investing assets, periodic reporting, and providing tax information regarding the trust. In exchange for these trust and custodial services, the Company collects fee income from beneficiaries as contractually determined via fee schedules. The Company’s performance obligation is primarily satisfied over time as the services are performed and provided to the customer. These fees are recorded under the accrual method of accounting as the services are performed. The Company generally acts as the principal in these transactions and records revenue and expenses on a gross basis. Bank Card and Automated Teller Machine (“ATM”) Fees Bank card and ATM fees include credit card, debit card and ATM transaction revenue. The majority of this revenue is card interchange fees earned through a third party network. Performance obligations are satisfied for each transaction when the card is used and the funds are remitted. The network establishes interchange fees that the merchant remits for each transaction, and costs are incurred from the network for facilitating the interchange with the merchant. Card fees also include merchant services fees earned for providing merchants with card processing capabilities. ATM income is generated from allowing customers to withdraw funds from other banks’ machines and from allowing a non-customer cardholder to withdraw funds from the Company’s machines. The Company satisfies its performance obligations for each transaction at the point in time that the withdrawal is processed. Bank card and ATM fee income is recorded on accrual basis as services are provided with the related expense reflected in data processing expense. Investment and Annuity Fees and Insurance Commissions Investment and annuity services fee income represents income earned from investment and advisory services. The Company provides its customers with access to investment products through the use of third party carriers to meet their financial needs and investment objectives. Upon selection of an investment product, the customer enters into a policy with the carrier. The performance obligation is satisfied by fulfilling its responsibility to acquire the investment for which a commission fee is earned from the carrier based on agreed-upon fee percentages on a trade date basis. The Company has a contractual relationship with a third party broker dealer to provide full service brokerage and investment advisory activities. As the agent in the arrangement, the Company recognizes the investment services commissions on a net basis. Investment revenue also includes portfolio management fees, which represent monthly fees charged on a contractual basis to customers for the management of their investment portfolios and are recorded under the accrual method of accounting on a gross basis, with expenses recorded in the appropriate expense line item. This revenue line item includes investment banking income, which includes fees for services arising from securities offerings or placements in which the Company acts as a principal. Revenue is recognized at the time the underwriting is completed and the revenue is reasonably determinable. Insurance commission revenue is recognized, net of cost, as of the effective date of the insurance policy as the Company’s performance obligation is connecting the customer to the insurance products. The Company also receives contingent commissions from insurance companies as additional incentive for achieving specified premium volume goals and/or the loss experience of the insurance placed. Contingent commissions from insurance companies are recognized when determinable, which is generally when such commissions are received or when we receive data from the insurance companies that allows the reasonable estimation of these amounts. Secondary Mortgage Market Operations Secondary mortgage market operations revenue is primarily comprised of service release premiums earned on the sale of closed-end mortgage loans to other financial institutions or government agencies that are recognized in revenue as each sales transaction occurs. Income from Bank-Owned Life Insurance Bank-owned life insurance income primarily represents income earned from the appreciation of cash surrender value of insurance contracts held and the proceeds of insurance benefits. Revenue from the proceeds of insurance benefits is recognized at the time a claim is confirmed. Credit Related Fee Income Credit-related fee income includes letters of credit fees and unused commercial commitment fees. Revenue for letters of credit fees is recognized over time. Revenue for unused commercial commitment fees are recognized based on contractual terms, generally when collected. Income from Derivatives Income from derivatives consists primarily of interest rate swap fees, net of fair value adjustments for customer derivatives and the related offsetting agreements with unrelated financial institutions for which the derivative instruments are not designated as hedges. This line item also includes the resulting gain or loss from ineffectiveness on derivatives that are designated as hedged items. Gain (Loss) on Sales of Assets Gain (loss) on sales of assets reflects the excess (deficiency) of proceeds received over the carrying amount assets sold plus cost to sell for various assets other than foreclosed real estate. Gain or loss on the sale of assets are recognized as each transaction occurs. Other Miscellaneous Income Other miscellaneous income represents a variety of revenue streams, including safe deposit box income, wire transfer fees, syndication fees and any other income not reflected above. Income is recorded once the performance obligation is satisfied, generally on the accrual basis or on a cash basis if not material and/or considered constrained.
