Great Southern’s total assets decreased $35.2 million, or 0.6%, from $5.81 billion at December 31, 2023, to $5.78 billion at March 31, 2024. Details of the current period changes in total assets are provided below, under “Comparison of Financial Condition at March 31, 2024 and December 31, 2023.”
Loans. Net outstanding loans decreased $3.4 million, or 0.1%, from $4.59 billion at December 31, 2023, to $4.59 billion at March 31, 2024. This decrease was primarily in commercial business loans, commercial real estate loans, construction loans and one- to four-family residential loans, significantly offset by an increase in other residential (multi-family) 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) 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, and Phoenix. Underwriting standards and monitoring procedures utilized by the Company are designed to help assure the Company’s portfolio quality. All new loan originations that exceed lender approval authorities are subject to review and approval by Great Southern’s loan committee. 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 or used motor vehicles and these loans are subject to underwriting standards designed to assure portfolio quality. In 2019, the Company discontinued indirect auto loan originations.
While our policy allows us to lend up to 95% of the appraised value on one-to four-family residential properties, originations of loans with loan-to-value ratios at that level are minimal. Private mortgage insurance is typically required for loan amounts above the 80% level. Few exceptions occur and would be based on analyses that determined minimal transactional risk to be involved. We consider these lending practices to be consistent with or more conservative than what we believe to be the norm for banks our size. At March 31, 2024 and December 31, 2023, 0.2% of our owner occupied one-to four-family residential loans had loan-to-value ratios above 100% at origination. At March 31, 2024 and December 31, 2023, an estimated 0.4% and 0.4% of total non-owner occupied one- to four-family residential loans had loan-to-value ratios above 100% at origination.
The level of non-performing loans and foreclosed assets affects our net interest income and net income. We generally do not accrue interest income on these loans and do not recognize interest income until the loans are repaid or interest payments have been made for a period of time sufficient to provide evidence of improved repayment ability on the loans. Generally, the higher the level of non-performing assets, the greater the negative impact on interest income and net income.
Available-for-sale Securities. In the three months ended March 31, 2024, available-for-sale securities decreased $12.9 million, or 2.7%, from $478.2 million at December 31, 2023, to $465.3 million at March 31, 2024.
Held-to-maturity Securities. In the three months ended March 31, 2024, held-to-maturity securities decreased $1.6 million, or 0.8%, from $195.0 million at December 31, 2023, to $193.4 million at March 31, 2024. See Note 5 “Investment Securities” in the Notes to Consolidated Financial Statements included in this report for additional information.
Deposits. The Company attracts deposit accounts through its retail branch network, correspondent banking and corporate services areas, internet channels and brokered deposits. The Company then utilizes these deposit funds, along with FHLBank advances and other borrowings, to meet loan demand or otherwise fund its activities. In the three months ended March 31, 2024, total deposit balances increased $51.7 million, or 1.1%. Compared to December 31, 2023, transaction account balances increased $60.4 million, or 1.9%, to $3.17 billion at March 31, 2024, and retail certificates of deposit decreased $32.7 million, or 3.5%, to $915.5 million at March 31, 2024. The increase in transaction accounts was primarily a result of an increase in various money market accounts as customers sought accounts paying a higher rate of interest. Retail time deposits decreased due to a decrease in retail certificates
