Credit Risk Transfers, Loan Sales and Securitizations. Growth in the loan origination pipeline has prompted the Company to seek additional avenues to effectively manage regulatory capital levels and reduce credit risk, in addition to issuing preferred and common stock. Accordingly, we have completed several loan sale and securitization transactions, as well as credit default swaps and credit linked notes. In doing so, the Company has been able to effectively reduce its risk-weighted assets and maintain well-capitalized capital ratios. Also see Note 5: Loans and Allowance for Credit Losses on Loans.
General and Administrative Expenses. We expect to continue incurring increased noninterest expense attributable to general and administrative expenses related to building out and modernizing our operational infrastructure, marketing, and other administrative expenses to execute our strategic initiatives, as well as expenses to hire additional personnel and other costs required to continue our growth. We also expect costs to increase with additional regulatory compliance requirements.
Comparison of Operating Results for the Years Ended December 31, 2024 and 2023
General. Net income of $320.4 million for the year ended December 31, 2024 increased by $41.2 million, or 15%, compared to net income of $279.2 million for the year ended December 31, 2023. The increase was primarily driven by a $74.5 million, or 17%, increase in net interest income, a $33.4 million, or 29%, increase in noninterest income, as well as $16.0 million, or 40%, decrease in provision for credit losses. The increases to net income were partially offset by a $49.2 million or 28%, increase in noninterest expense.
Net Interest Income. Net interest income of $522.6 million for the year ended December 31, 2024 increased $74.5 million, or 17%, compared to $448.1 million for the year ended December 31, 2023. The 17% increase reflected a $224.9 million, or 21% increase in interest income from higher average balances and yields on loans and loans held for sale, and higher average balances of securities held to maturity, as well as higher yields and average balances on securities available for sale. These increases were partially offset by a $150.4 million, or 24%, increase in interest expense primarily due to higher average balances on borrowings, as well as higher average balances and rates on certificates of deposit and interest-bearing checking.
The interest rate spread of 2.47% for the year ended December 31, 2024, decreased 4 basis points compared to 2.51% for the year ended December 31, 2023. Our net interest margin decreased 3 basis points, to 3.03%, for the year ended December 31, 2024 from 3.06% for the year ended December 31, 2023.
