Schedule of Aging of Loans

The following tables provide an analysis of the aging of loans and leases as of December 31, 2019 and 2018. Past due and non-accrual loan amounts exclude acquired impaired loans, even if contractually past due or if the Company does not expect to receive payment in full, as the Company is currently accreting interest income over the expected life of the loans. For additional information on the determination of past due status and the Company's policies for recording payments received, placing loans and leases on non-accrual status, and the resumption of interest accrual on non-accruing loans and leases, See Note 1, Summary of Significant Accounting Policies.
