Our SBA 7(a) program lending activities also follow underwriting standards and loan origination procedures established by our Board of Directors and management. Certain of our employees have been granted individual lending limits, which is $2.0 million for the aggregate loan balance, of which 75% or greater is guaranteed by the SBA. Generally, all SBA 7(a) program loan requests for lending relationships that exceed the individual officer lending limits require approval by the SBA Officer Loan Committee. The SBA Officer Loan Committee consists of the President, Chief Financial Officer, Chief Lending Officer, Chief of Credit Administration, Chief of SBA Lending, Senior SBA Lending Officer and a senior commercial lending officer. The aggregated lending relationships for the SBA 7(a) program may not exceed $5.0 million according to SBA guidelines and therefore no loan requests require approval by the Board of Directors given that the portion of SBA 7(a) program loans that are not guaranteed by the SBA may not exceed $1.25 million.
Loans to One Borrower. The maximum amount that we may lend to one borrower and the borrower’s related entities is limited, by regulation, to generally 15% of our stated capital and reserves. At September 30, 2022, our regulatory limit on loans to one borrower was $31.4 million. At that date, our largest lending relationship was for a commitment of $26.9 million, of which $21.0 million was outstanding, and was performing according to its original terms at that date.
Loan Commitments. We issue commitments for commercial loans conditioned upon the occurrence of certain events. Commitments to originate loans are legally binding agreements to lend to our customers. Generally, our loan commitments expire after 30 days. See Note 17, “Commitments and Contingencies” of the Notes to Consolidated Financial Statements beginning on page F-1 of this annual report for additional information regarding our loan commitments at September 30, 2022.
Investment Activities
We have legal authority to invest in various types of liquid assets, including U.S. Treasury obligations, securities of various U.S. government agencies and sponsored enterprises, securities of various state and municipal governments, mortgage-backed securities, collateralized mortgage obligations and certificates of deposit of federally insured institutions. Within certain regulatory limits, we also may invest a portion of our assets in other permissible securities. As a member of the Federal Reserve System and Federal Home Loan Bank System, in particular a member of the Federal Home Loan Bank of Indianapolis (“FHLB”), First Savings Bank is also required to acquire and hold shares of capital stock in the Federal Reserve Bank and FHLB.
At September 30, 2022, our investment portfolio consisted primarily of U.S. Treasury notes, government agency and sponsored enterprises securities, mortgage backed securities and collateralized mortgage obligations issued by U.S. government agencies and sponsored enterprises, municipal bonds, privately-issued collateralized mortgage obligations and asset-backed securities, and pass-through asset-backed securities guaranteed by the SBA.
Our investment objectives are to provide and maintain liquidity, to establish an acceptable level of interest rate and credit risk, and to provide an alternate source of low-risk investments at a favorable return when loan demand is weak. Our Board of Directors has the overall responsibility for the investment portfolio, including approval of the investment policy. Messrs. Myers, our President and Chief Executive Officer, and Schoen, our Chief Financial Officer, are responsible for implementation of the investment policy and monitoring our investment performance. Our Board of Directors reviews the status of our investment portfolio on a quarterly basis, or more frequently if warranted.
Deposit Activities and Other Sources of Funds
General. Deposits, borrowings, and loan and investment security repayments are the major sources of our funds for lending and other investment purposes. Scheduled loan repayments are a relatively stable source of funds, while deposit inflows and outflows, loan prepayments and investment security calls are significantly influenced by general interest rates and money market conditions.
Deposit Accounts. Deposits are attracted from within our primary market area through the offering of a broad selection of deposit instruments, including non-interest-bearing demand deposits (such as checking accounts), interest-bearing demand accounts (such as NOW and money market accounts), regular savings accounts and time deposits. Deposit account terms vary according to the minimum balance required, the time periods the funds must remain on deposit and the interest rate, among other factors. In determining the terms of our deposit accounts, we consider the rates offered by our competition, our liquidity needs, profitability to us, matching deposit and loan products and customer preferences and concerns. We generally review our deposit mix and pricing weekly. Our deposit pricing strategy has typically been to offer competitive rates on all types of deposit products, and to periodically offer special rates in order to attract deposits of a specific type or term.
