the same period in 2023. Return on average equity for the three-month period ended March 31, 2024, was 0.06% compared to 9.9% for the three-month period ended March 31, 2023. Lower net income and a higher average equity balance primarily drove the lower return on average equity for the three-month period ended March 31, 2024, compared to the same periods in 2023.
The book value per share of Bancorp’s common stock was $6.28 on March 31, 2024, as compared to $6.36 per share on March 31, 2023. The decrease primarily resulted from the unrealized losses on the Company’s available for sale securities and the higher level of interest rates in 2024.
At March 31, 2024, the Bank remained above all “well-capitalized” regulatory requirement levels. The Bank’s tier 1 risk-based capital ratio was 17.14% at March 31, 2024, compared to 17.37% at December 31, 2023.
Our liquidity position remained strong due to managed cash and cash equivalents, borrowing lines with the Federal Reserve Bank, the FHLB of Atlanta and correspondent banks, and the size and composition of the bond portfolio.
RESULTS OF OPERATIONS
Net income attributable to common stockholders for the three-month period ended March 31, 2024, was $3,000, or $0.00 per basic and diluted common share compared to $435,000, or $0.15 per basic and diluted common share for the same period of 2023. The results for the three-month period ended March 31, 2024, were lower than the same period of 2023 resulting primarily from a $431,000 increase in interest expense on short-term borrowings, a $295,000 increase in interest expense on deposits and a $211,000 increase in the provision for credit losses on loans, partially offset by an increase of $128,000 in loan interest income and fees and a $318,000 decrease in the provision for income taxes. The Company’s need to defend its deposit base as well as grow interest-earning asset balances necessitated a strategic change in direction.
Net Interest Income. The Company’s net interest income for the three-month period ended March 31, 2024 was $2.6 million, as compared to $3.2 million for the same period in 2023, a decrease of $606,000, or 19.07%. The decrease in net interest income was primarily due to the $726,000 increase in interest expense related to higher balances and rates on money market deposits and short-term borrowings partially offset by higher interest income.
Total interest income for the first quarter of 2024 increased $120,000, or 3.65% when compared to the same period in 2023, from $3.3 million in 2023 to $3.4 million in 2024. The primary driver of the increase was a $128,000, or 6.13%, increase in interest and fees on loans due to higher rates and $19,000 increase in interest on deposits with banks and federal funds that were partially offset by a $27,000 decrease in interest and dividends on investment securities due to maturities subsequent to the first quarter of 2023.
Interest expense for the first quarter of 2024 increased $726,000 from $107,000 for the same period in 2023 to $833,000, an increase of 678.50%. The increase was attributable to higher balances and rates on money market deposits and short-term borrowings.
Net interest margin for the three-month period ended March 31, 2024 was 2.86% compared to 3.41% for the three-month period ended March 31, 2023, a decrease of 0.55%. The decrease in the net interest margin is due to increases in average deposit costs and short-term borrowing costs, partially offset by increases in yields on investment securities, loans, and interest-bearing deposits at the Federal Reserve Bank. Loan yields increased from 4.58% to 5.06% between the two periods while the cost of interest-bearing liabilities increased from 0.20% to 1.51% between the two periods.
The average balance of interest-earning assets decreased $16.3 million while the yield increased by 0.26% to 3.78% from 3.52%, when comparing the three-month periods ending March 31, 2024, and 2023, respectively. The average balance of interest-bearing funds increased $8.1 million. The average balance of noninterest-bearing funds decreased $24.4 million, and the cost of funds increased 0.87%, to 0.99% from 0.12% when comparing the three-month periods ending March 31, 2024, and 2023, respectively.
