Originated loans and leases represent originations excluding loans initially acquired in a business combination. However, once an acquired non-impaired loan reaches its maturity date, and is re-underwritten and renewed, it is internally classified as an originated loan. Acquired impaired loans are loans acquired from a business combination with evidence of credit quality deterioration and are accounted for under ASC Topic 310-30. Acquired non-impaired loans and leases represent loans and leases acquired from a business combination without more than insignificant evidence of credit quality deterioration and are accounted for under ASC Topic 310-20. Acquired leases and revolving loans having evidence of credit quality deterioration do not qualify to be accounted for as acquired impaired loans and are accounted for under ASC Topic 310-20. The following tables summarize the balances for each respective loan and lease category as of September 30, 2020 and December 31, 2019:
