Noninterest income for the first quarter 2021 was up $1,501,000 from the first quarter 2020 total. Net gains from sales of loans of $1,064,000 for the first quarter 2021 were up $749,000 from the total for the first quarter 2020, reflecting an increase in volume of mortgage loans sold due mainly to the impact of historically low interest rates on the housing market and refinancing activity mentioned earlier. Other significant contributors to the overall increase were greater income from tax credits related to PA Educational Improvement Tax Credit Program donations ($262,000), loan servicing income ($262,000), interchange fees ($150,000), and trust revenues ($147,000), while service charges on deposit accounts declined ($235,000).
Noninterest expense, excluding merger-related expenses, increased $2,797,000 in the first quarter 2021 over the first quarter 2020 amount. Nearly all categories were impacted by the Covenant acquisition including salaries and employee benefits, net occupancy expenses, and IT and related contract expenses. Donations expenses also rose consistent with the tax credit revenue mentioned previously. The result, however, is that total revenues increased substantially more than expenses, resulting in an efficiency ratio of just under 58% in the first quarter of 2021 compared to 65% in the first quarter of 2020.
C&N strength continues to be reflected in capital ratios, which are at levels that demonstrate the capacity to absorb significant credit losses, if they arise, while continuing to meet regulatory requirements to be considered well capitalized. In January, the Board approved and announced a stock repurchase program of up to 1 million shares in open market transactions, replacing the existing program that included up to 600,000 shares. No purchases were made during the first quarter. In April, the Board declared a regular quarterly cash dividend of $.28 per share to shareholders of record on May 3, 2021, payable on May 14, 2021. This is a 3.7% increase from the $.27 quarterly cash dividend paid during 2020 and the first quarter 2021.
In closing, I want to thank the C&N Team for their ongoing commitment to our Company’s mission. In addition to the results and accomplishments set forth in this letter, their support of the community through GBGT continues to be extraordinary. Please review the Community&Commitment section of this report for the details.
As always, we appreciate your confidence in this team and support of our Company. We have started 2021 with a strong first quarter and hope to see many of you in person as the world reopens in the months ahead.
