Comparison of Operating Results for the Three Months Ended June 30, 2020 and 2019
General. Net income decreased by $769,000, or 15.2%, to $4.3 million for the three months ended June 30, 2020 from $5.1 million for the three months ended June 30, 2019. The decrease in net income was primarily due to a $1.4 million increase in provision for loan losses and a $1.1 million decrease in interest income. These decreases to net income were partially offset by decreases of $1.2 million and $540,000 in interest expense and noninterest expense, respectively.
Net Interest Income. Net interest income increased by $104,000, or 0.7%, to $14.8 million for the three months ended June 30, 2020 from $14.7 million for the three months ended June 30, 2019. Interest income decreased by $1.1 million, or 5.8%, primarily due to a 23 basis point decrease in the average yield on average interest-earning assets, which was partially offset by a $9.2 million increase in the average balance of interest-earning assets. Interest expense decreased by $1.2 million, or 27.2%, due to a 28 basis point decrease in the cost of average interest-bearing liabilities. The interest rate spread and net interest margin were 2.84% and 2.94%, respectively, for the three months ended June 30, 2020, compared to 2.79% and 2.93%, respectively, for the three months ended June 30, 2019. The increases in the interest rate spread and in the net interest margin are attributable to the 28 basis point decrease in the cost of average interest-earning liabilities, which was partially offset by the 23 basis point decrease in the yield of average interest-bearing assets.
Interest Income. Interest income decreased by $1.1 million, or 5.8%, to $18.0 million for the three months ended June 30, 2020 from $19.1 million for the three months ended June 30, 2019. Interest income on loans decreased by $778,000, or 4.9%, to $15.2 million for the three months ended June 30, 2020 from $16.0 million for the three months ended June 30, 2019. The decrease in interest income on loans occurred because of a $36.4 million, or 2.3%, decrease in the average loan balances and an 11 basis point decrease in the average loan yield. The decrease in the average loan balances occurred as loan repayments and loan sales exceeded new loan originations. Interest income on securities decreased by $237,000, or 8.3%, to $2.6 million for the three months ended June 30, 2020 from $2.8 million for the three months ended June 30, 2019. The decrease in interest income on securities occurred because the average balance of securities decreased by $13.8 million, or 3.7%, and because of a 15 basis point decline in the average securities yield, which occurred as higher yielding securities were paid off or sold. The decrease in the average security balance was due to security repayments and sales.
Interest Expense. Interest expense decreased by $1.2 million, or 27.2%, to $3.2 million for the three months ended June 30, 2020 from $4.5 million for the three months ended June 30, 2019. The decrease in interest expense occurred because interest expense on interest bearing deposits decreased by $1.2 million, or 32.7%, to $2.4 million for the three months ended June 30, 2020 from $3.5 million for the three months ended June 30, 2019. The decrease in interest expense on interest bearing deposits was due to a 28 basis point decrease in the average rate on interest bearing deposits and a $20.4 million, or 1.3%, decrease in the average interest bearing deposit balance. The average rate paid on interest bearing deposits decreased to 0.60% for the three months ended June 30, 2020 compared to 0.88% for the three months ended June 30, 2019. The decrease in the average rate paid on interest bearing deposits was primarily due to lower interest rates offered on savings accounts and certificates of deposit. The average rate paid on savings accounts decreased to 0.23% for the three months ended June 30, 2020 from 0.49% for the three months ended June 30, 2019. The average rate paid on certificates of deposit decreased to 1.66% for the three months ended June 30, 2020 from 2.02% for the three months ended June 30, 2019. The decrease in the average balance of deposits was primarily due to a decrease in the average balance of savings accounts and certificates of deposit. The average balance of savings accounts decreased by $24.8 million, or 2.6%, to $922.0 million from $946.8 million. The average balance of certificates of deposit decreased by $24.2 million, or 5.2%, to $437.3 million from $461.5 million.
Provision for Loan Losses. We recorded provisions for loan losses of $1.4 million and reversals of provisions for loan losses of $51,000 for the three months ended June 30, 2020 and June 30, 2019, respectively. The increase in provisions in 2020 resulted from an increase in the qualitative factors used to calculate the allowance for loan losses. The qualitative factors were raised because Hawaii’s unemployment rate increased due to layoffs that occurred as a result of government mandates that were put in place to minimize the spread of COVID-19. The provisions recorded resulted in ratios of the allowance for loan losses to total loans of 0.28% at June 30, 2020 and 0.16% at June 30, 2019. Nonaccrual loans totaled $763,000 at June 30, 2020, or 0.05% of total loans at that date, compared to $892,000 of
