COVID-19.

Total loans and leases, net of deferred fees and discounts, of $8.41 billion at September 30, 2020 increased by $843.3 million, or 11.15%, from December 31, 2019. The increase in total loans included $1.10 billion in PPP loans and a $130.9 million decline in dairy & livestock and agribusiness loans primarily due to seasonal pay downs, which historically occur in the first quarter of each calendar year. Excluding PPP loans and dairy & livestock and agribusiness loans, total loans declined by $126.9 million, or 1.77%.

This decline was primarily due to the impact of the Federal Reserve’s rate decreases and the decline in discount accretion income for acquired loans. Interest income for yield adjustments related to discount accretion on acquired loans was $4.2 million for the quarter ended September 30, 2020, compared to $4.1 million for the second quarter of 2020 and $7.2 million for the third quarter of 2019.
