Interest and Dividend Income. Total interest and dividend income decreased $276,000, or 3.0%, to $9.0 million for the three months ended March 31, 2020 compared to $9.3 million for the three months ended March 31, 2019. The decrease was primarily the result of an 18 basis point decrease in the average yield on interest-earning assets to 3.96% for the three months ended March 31, 2020 from 4.14% for the same period in the prior year.
Interest income on loans decreased $203,000, or 2.5%, to $7.8 million for the three months ended March 31, 2020 compared to $8.0 million for the three months ended March 31, 2019. The decrease was primarily the result of a decrease in the average balance of loans receivable of $18.8 million, or 2.6%, to $712.5 million for the three months ended March 31, 2020 compared to the prior period. Additionally, there was a three basis point decrease in the average yield on loans receivable to 4.36% for the three months ended March 31, 2020 from 4.39% for the same period in the prior year.
Interest income on investment and mortgage-backed securities decreased $50,000, or 4.8%, to $992,000 for the three months ended March 31, 2020 compared to $1.0 million for the three months ended March 31, 2019. The decrease was primarily the result of a 27 basis point decrease in the average yield earned on investment and mortgage-backed securities to 2.49% for the quarter ended March 31, 2020 from 2.76% for the same period in the prior year. The decrease in the average yield was due to falling interest rates during the period. The decrease in interest income resulting from the decrease in the average yield was partially offset by an increase in the average balance of investment and mortgage-backed securities of $8.3 million, or 5.5%, to $159.5 million for the three months ended March 31, 2020 compared to the prior year.
Dividend income on FHLB and other restricted stock decreased $31,000, or 17.8%, to $143,000 for the three months ended March 31, 2020 compared to $174,000 for the three months ended March 31, 2019. The decrease primarily resulted from a decrease in the average yield to 7.57% for the three months ended March 31, 2020 from 9.02% for the same period in the prior year. The higher yield in the 2019 quarter resulted from a higher dividend received for the fourth quarter 2018 than was accrued as a result of the FHLB increasing the dividend yield on both activity and membership stock. There was also a decrease in the average balance of FHLB stock and other restricted stock of $270,000, or 3.4%, to $7.6 million for the three months ended March 31, 2020 compared to the prior period.

The increase was primarily the result of an increase in the average balance of interest-earning deposits of $15.6 million, or 127.3%, to $27.8 million for the three months ended March 31, 2020 compared to the prior period. The increase in interest income resulting from the increase in the average balance was partially offset by a decrease in the average yield on interest-earning deposits to 1.28% for the three months ended March 31, 2020 from 2.67% for the same period in the prior year as a result of falling short-term interest rates during the period.
Interest Expense. Total interest expense was $2.2 million for both the three months ended March 31, 2020 and the three months ended March 31, 2019. The average cost and average balance of interest-bearing deposits were both higher for the three months ended March 31, 2020 compared to the three months ended March 31, 2019, however, this increase was partially offset by a decrease in the average balance of borrowings for the same period.
Interest expense on deposits increased $79,000, or 5.0%, to $1.7 million for the three months ended March 31, 2020 from $1.6 million for the three months ended March 31, 2019. The increase was primarily the result of a 2 basis points increase in the average cost of interest-bearing deposits to 1.12% for the three months ended March 31, 2020 from 1.10% for the same period in the prior year due to higher interest rates for much of the quarter. Additionally, there was an increase in the average balance of interest-bearing deposits of $12.4 million, or 2.1%, for the three months ended March 31, 2020 compared to the same period in the prior year.

The decrease was primarily the result of a decrease in the average balance of borrowings of $6.0 million, or 5.7%, to $99.2 million for the three months ended March 31, 2020 compared to the same period in the prior year.
Provision for Loan Losses. Provision for loan losses increased $442,000, or 409.3%, to $550,000 for the three months ended March 31, 2020 compared to $108,000 for the three months ended March 31, 2019. The provision for the quarter was impacted by a number of things including increases in several qualitative factors, some of which were directly impacted by the COVID-19 pandemic, an increase in the loan balances included in the allowance calculation and increased reserves required on a few loans which experienced a deterioration in quality from the previous quarter.
