For the first quarter of 2020, we reported net earnings of $38.0 million, compared with $51.3 million for the fourth quarter of 2019 and $51.6 million for the first quarter of 2019. Diluted earnings per share were $0.27 for the first quarter, compared to $0.37 for the prior quarter and $0.37 for the same period last year.
The implementation of CECL resulted in a beginning balance transition adjustment to our allowance for credit losses (“ACL”) of $1.8 million with a cumulative effect adjustment to beginning retained earnings of $1.3 million, net of tax. A $12.0 million credit loss provision was recorded for the first quarter of 2020, due primarily to the forecasted economic disruption resulting from
COVID-19.
During the quarter, we experienced minimal credit charge-offs of $86,000 and total recoveries of $227,000, resulting in net recoveries of $141,000.

Total loans and leases, net of deferred fees and discounts, of $7.47 billion at March 31, 2020 decreased by $98.4 million, or 1.30%, from December 31, 2019. The decrease in total loans included a $111.6 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 dairy and livestock loans, total loans grew by $13.2 million, or 0.18%. The $13.2 million increase in loans included increases of $25.6 million in commercial and industrial loans, $11.1 million in construction loans, and $8.1 million in SBA loans, partially offset by a $26.7 million decrease in commercial real estate loans and collectively a $4.9 million decline in other loan segments.

At March 31, 2020, noninterest-bearing deposits were 61.15% of total deposits, compared to 60.26% at December 31, 2019. Given what is typically a seasonally low quarter for us, deposit growth for the first quarter of 2020 was strong, although some of this growth was inflated by approximately $100 million of short-term noninterest-bearing deposits at the end of the first quarter. Our average cost of total deposits was 0.19% for the quarter ended March 31, 2020, compared to 0.21% for the fourth quarter of 2019 and 0.18% for the first quarter of 2019.
Customer repurchase agreements totaled $368.9 million at March 31, 2020, compared to $428.7 million at December 31, 2019.

The allowance for credit losses totaled $82.6 million at March 31, 2020, compared to $68.7 million at December 31, 2019. Due to the adoption of CECL, effective on January 1, 2020, a transition adjustment of $1.8 million was added to the beginning balance of the allowance and was increased by $12.0 million in provision for credit losses in the first quarter of 2020 due to the severe economic disruption forecasted to result from the coronavirus pandemic. The allowance for credit losses was 1.11% and 0.91% of total loans and leases outstanding, at March 31, 2020 and December 31, 2019, respectively. As of March 31, 2020, total discounts on acquired loans were $43.4 million.
The Company’s total equity was $1.94 billion at March 31, 2020. This represented a decrease of $52.7 million, or 2.64%, from total equity of $1.99 billion at December 31, 2019. This decrease was primarily due to repurchase of common stock of $91.7 million under our 10b5-1 stock repurchase program, that was offset by a $25.8 million increase in other comprehensive income resulting from the tax effected impact of the increase in market value of our investment securities portfolio. Equity also increased by $13.6 million in retained earnings for the quarter after $24.4 million in cash dividends were declared by the Company for the first quarter of 2020. Our tangible common equity ratio was 11.3% at March 31, 2020.
