Paycheck Protection Program Loans
Great Southern actively participated in the Paycheck Protection Program (“PPP”) through the SBA. In total, we originated approximately 3,250 PPP loans, totaling approximately $179 million. SBA forgiveness was approved and processed, and full repayment proceeds were received by us, for virtually all of these PPP loans during 2021 and early 2022.
Great Southern received fees from the SBA for originating PPP loans based on the amount of each loan. At December 31, 2022, there were no material remaining net deferred fees related to PPP loans. The fees, net of origination costs, were deferred in accordance with standard accounting practices and accreted to interest income on loans over the contractual life of each loan. If loans are repaid prior to their contractual maturity date, remaining deferred fees are accreted to interest income at that time. In the years ended December 31, 2022 and 2021, Great Southern recorded approximately $502,000 and $5.5 million, respectively, of net deferred fees in interest income on PPP loans.
General
The profitability of the Company and, more specifically, the profitability of its primary subsidiary, the Bank, depend primarily on its net interest income, as well as provisions for credit losses and the level of non-interest income and non-interest expense. Net interest income is the difference between the interest income the Bank earns on its loans and investment portfolios, and the interest it pays on interest-bearing liabilities, which consists mainly of interest paid on deposits and borrowings. Net interest income is affected by the relative amounts of interest-earning assets and interest-bearing liabilities and the interest rates earned or paid on these balances. When interest-earning assets approximate or exceed interest-bearing liabilities, any positive interest rate spread will generate net interest income.
In the year ended December 31, 2022, Great Southern’s total assets increased $230.8 million, or 4.2%, from $5.45 billion at December 31, 2021, to $5.68 billion at December 31, 2022. Full details of the current year changes in total assets are provided below, under “Comparison of Financial Condition at December 31, 2022 and December 31, 2021.”
Loans. In the year ended December 31, 2022, Great Southern’s net loans increased $499.3 million, or 12.5%, from $4.01 billion at December 31, 2021, to $4.51 billion at December 31, 2022. This increase was primarily in one- to four-family residential loans, construction loans, other residential (multi-family) loans, and commercial real estate loans. As loan demand is affected by a variety of factors, including general economic conditions, and because of the competition we face and our focus on pricing discipline and credit quality, we cannot be assured that our loan growth will match or exceed the average level of growth achieved in prior years. The Company’s strategy continues to be focused on maintaining credit risk and interest rate risk at appropriate levels.
Recent growth has occurred in some loan types, primarily other residential (multi-family), commercial real estate and one- to four family residential real estate, and in most of Great Southern’s primary lending locations, including Springfield, St. Louis, Kansas City, Des Moines and Minneapolis, as well as our loan production offices in Atlanta, Charlotte, Chicago, Dallas, Denver, Omaha, Phoenix and Tulsa. Certain minimum underwriting standards and monitoring help assure the Company’s portfolio quality. Great Southern’s loan committee reviews and approves all new loan originations in excess of lender approval authorities. Generally, the Company considers commercial construction, consumer, other residential (multi-family) and commercial real estate loans to involve a higher degree of risk compared to some other types of loans, such as first mortgage loans on one- to four-family, owner-occupied residential properties. For other residential (multi-family), commercial real estate, commercial business and construction loans, the credits are subject to an analysis of the borrower’s and guarantor’s financial condition, credit history, verification of liquid assets, collateral, market analysis and repayment ability. It has been, and continues to be, Great Southern’s practice to verify information from potential borrowers regarding assets, income or payment ability and credit ratings as applicable and as required by the authority approving the loan. To minimize construction risk, projects are monitored as construction draws are requested by comparison to budget and with progress verified through property inspections. The geographic and product diversity of collateral, equity requirements and limitations on speculative construction projects help to mitigate overall risk in these loans. Underwriting standards for all loans also include loan-to-value ratio limitations which vary depending on collateral type, debt service coverage ratios or debt payment to income ratio guidelines, where applicable, credit histories, use of guaranties and other recommended terms relating to equity requirements, amortization, and maturity. Consumer loans, other than home equity loans, are primarily secured by new and used motor vehicles and
