On January 1, 2018, the Company implemented ASU 2014-09, Revenue from Contracts with Customers, codified at ASC Topic 606. The majority of the Company’s revenue is generated through interest earned on financial instruments, including loans and investment securities, which falls outside the scope of ASC Topic 606. The Company also generates revenue from insurance- and lease-related contracts that fall outside the scope of ASC Topic 606.

All of the Company’s revenue that is subject to ASC Topic 606 is included in non-interest income; however, not all non-interest income is subject to ASC Topic 606. Revenue earned by the Company that is subject to ASC Topic 606 primarily consists of service and other charges on deposit accounts, mortgage fees from secondary market transactions at the Bank, ATM fee income and other non-interest income. Revenue generated from these sources for the six-month periods ended June 30, 2020 and 2019 was $1.4 million and $1.6 million, respectively, and for the three-month periods ended June 30, 2020 and 2019 was $0.6 million and $0.8 million, respectively. All sources of the Company’s revenue subject to ASC Topic 606 are transaction-based, and revenue is recognized at the time at which the transaction is executed, which is the same time at which the Company’s performance obligation is satisfied. The Company had no contract liabilities or unsatisfied performance obligations with customers as of June 30, 2020.
