These classification changes resulted in immaterial changes to both revenue and expense.

Revenue from Contracts with Customers

The Company records revenue from contracts with customers in accordance with Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods.

The Company’s primary sources of revenue are derived from interest and fees earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers.

The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contract-revenue (i.e. gross versus net). Based on the evaluation, the Company determined that the classification of certain debit and credit card processing related costs should change (i.e. costs previously recorded as expense in now recorded as contract-revenue). These classification changes resulted in immaterial changes to both revenue and expense. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to beginning retained earnings was not deemed necessary.
