Provision for Loan Losses. For the six months ended June 30, 2020, the provision for loan losses was $8.3 million, compared to $1.7 million for the six months ended June 30, 2019, due primarily to the incurred but not yet reported probable loan losses reflecting credit deterioration due to the adverse impact of the COVID-19 pandemic, the increase in the loan portfolio due to organic growth and net loan charge-offs. During the six months ended June 30, 2020, net loan charge-offs totaled $40,000, compared to net loan charge-offs of $1.7 million during the six months ended June 30, 2019. A further decline in national and local economic conditions, as a result of the COVID-19 pandemic or other factors, could result in a material increase in the allowance for loan losses and may adversely affect the Company’s financial condition and results of operations.
Noninterest Income. Noninterest income increased $12.4 million, or 116.4%, to $23.0 million for the six months ended June 30, 2020, from $10.6 million for the six months ended June 30, 2019. The increase between periods was driven by a $13.3 million increase in gain on sale of loans, primarily due to higher sales volume, and a $1.4 million, or 208.4% increase in other noninterest income, mostly due to the one-time sale of Class B Visa stock shares of $1.5 million in the first quarter. These increases were partially offset by a $2.5 million, or 71.0% decrease in net service charges and fee income, primarily due to an increase in amortization expense attributable to the Bank’s mortgage servicing rights reflecting the reduction in market interest rates. The increased amortization was primarily a result of higher volumes of payoffs in the underlying servicing portfolio.
Noninterest Expense. Noninterest expense decreased $1.1 million, or 3.3%, to $30.8 million for the six months ended June 30, 2020, from $31.9 million for the six months ended June 30, 2019. The decrease was primarily due to no acquisition costs in the current period, compared to $1.6 million for the six months ended June 30, 2019 associated with the Anchor Bank core conversion. Other decreases included $591,000 in data processing and $428,000 in loan costs, partially offset by increases of $1.2 million in the impairment of servicing rights and $274,000 in operations.
The efficiency ratio, which is noninterest expense as a percentage of net interest income and noninterest income, improved to 52.79% for the six months ended June 30, 2020, compared to 69.49% for the six months ended June 30, 2019, representing the increase in noninterest income and the decreases in noninterest expense noted above.
Provision for Income Tax. For the six months ended June 30, 2020, the Company recorded a provision for income tax expense of $4.0 million on pre-tax income of $19.2 million, as compared to a provision of income tax expense of $2.7 million on pre-tax income of $12.3 million for the six months ended June 30, 2019. The effective corporate income tax rates for the six months ended June 30, 2020 and 2019 were 21.0% and 21.7%, respectively.
Liquidity
Management maintains a liquidity position that it believes will adequately provide funding for loan demand and deposit runoff that may occur in the normal course of business. The Company relies on a number of different sources in order to meet potential liquidity demands. The primary sources are increases in deposit accounts, FHLB advances, purchases of federal funds, sale of securities available-for-sale, cash flows from loan payments, sales of one-to-four-family loans held for sale, and maturing securities.
At June 30, 2020, the Bank’s total borrowing capacity was $573.3 million with the FHLB of Des Moines, with unused borrowing capacity of $480.0 million. The FHLB borrowing limit is based on certain categories of loans, primarily real estate loans that qualify as collateral for FHLB advances. At June 30, 2020, the Bank held approximately $769.0 million in loans that qualify as collateral for FHLB advances.
In addition to the availability of liquidity from the FHLB of Des Moines, the Bank maintained a short-term borrowing line with the FRB, with a current limit of $159.5 million, and a combined credit limit of $101.0 million in written federal funds lines of credit through correspondent banking relationships at June 30, 2020. The FRB borrowing limit is based on certain categories of loans, primarily consumer loans that qualify as collateral for FRB line of credit. At June 30, 2020, the Bank held approximately $336.0 million in loans that qualify as collateral for the FRB line of credit. The Bank also had available liquidity from the PPPFL, pursuant to which the Company can pledge its PPP loans as collateral at face value to obtain FRB non-recourse loans. As of June 30, 2020, the Company had pledged $63.0 million in PPP loans under the PPPFL, with additional PPP loans of $12.3 million that qualify as collateral for additional advances under the PPPFL.
