Total liabilities were $2.6 billion at December 31, 2021, an increase of $200.3 million, or 8.3%, as compared to June 30, 2021.
Deposits were $2.6 billion at December 31, 2021, an increase of $221.4 million, or 9.5%, as compared to June 30, 2021. This increase primarily reflected an increase in interest-bearing transaction accounts, non-interest bearing transaction accounts, savings accounts, and money market deposit accounts, partially offset by a decrease in certificates of deposit. The increase was inclusive of a $91.4 million increase in public unit funds, and net of a $5.0 million decrease in brokered deposits. Public unit funds totaled $417.8 million at December 31, 2021, primarily in nonmaturity deposits, while brokered deposits totaled $20.1 million, and were comprised fully of nonmaturity deposits. The Company’s branch purchase and assumption agreement, through which it acquired the former Cairo, Illinois, location of the First National Bank (Fulda, SD), provided deposit growth of $28.5 million, including $15.4 million in public unit deposits. Customers have held unusually high balances on deposit during recent periods, but the Company expects that some of the higher-than-normal balances may dissipate over the course of calendar year 2022. The average loan-to-deposit ratio for the second quarter of fiscal 2022 was 93.6%, as compared to 98.5% for the same period of the prior fiscal year.
FHLB advances were $36.5 million at December 31, 2021, a decrease of $21.0 million, or 36.5%, as compared to June 30, 2021, as the Company utilized cash to repay maturing term advances.
The Company’s stockholders’ equity was $301.6 million at December 31, 2021, an increase of $18.2 million, or 6.4%, as compared to June 30, 2021. The increase was attributable primarily to earnings retained after cash dividends paid, partially offset by a reduction in other comprehensive income and by repurchases of the Company’s common stock. During the first six months of fiscal 2022, the Company repurchased 26,607 common shares for $1.2 million, at an average price of $44.15.
Quarterly Income Statement Summary:
The Company’s net interest income for the three-month period ended December 31, 2021, was $25.1 million, an increase of $1.5 million, or 6.5%, as compared to the same period of the prior fiscal year. The increase was attributable to a 10.5% increase in the average balance of interest-earning assets, partially offset by a decrease in net interest margin to 3.77% in the current three-month period, from 3.92% in the same period a year ago. As a material amount of PPP loans were forgiven, and therefore repaid ahead of their scheduled maturity, the Company recognized accelerated accretion of interest income from deferred origination fees on these loans. In the current quarter, this component of interest income totaled $890,000, adding 13 basis points to the net interest margin, as compared to $968,000, or 16 basis points, in the year ago period. In the linked quarter, ended September 30, 2021, accelerated accretion of deferred origination fees on PPP loans totaled $2.2 million, adding 34 basis points to the net interest margin. The remaining balance of deferred origination fees is significantly less than the amount accreted in recent quarters.
Loan discount accretion and deposit premium amortization related to the Company’s August 2014 acquisition of Peoples Bank of the Ozarks, the June 2017 acquisition of Capaha Bank, the February 2018 acquisition of Southern Missouri Bank of Marshfield, the Gideon Acquisition, and the Central Federal Acquisition resulted in $381,000 in net interest income for the three-month period ended December 31, 2021, as compared to $516,000 in net interest income for the same period a year ago. The Company generally expects this component of net interest income to decline over time, although volatility may occur to the extent we have periodic resolutions of specific loans. Combined, this component of net interest income contributed six basis points to net interest margin in the three-month period ended December 31, 2021, as compared to a contribution of nine basis points in the same period of the prior fiscal year, and a six basis point contribution in the linked quarter, ended September 30, 2021, when net interest margin was 4.01%.
