Comparison of Operating Results for the Three Months Ended June 30, 2022 and 2021
General. Net income for the three months ended June 30, 2022 was $53.9 million, an increase of $2.5 million, or 5%, from net income for the three months ended June 30, 2021. The increase was primarily due to a $16.8 million, or 23% increase in interest income and a $7.0 million higher fair market value adjustment to servicing rights.
Partially offsetting the increases to net income was a $9.2 million increase in interest expense, a $6.5 million increase in the provision for credit losses, a $4.8 million increase in noninterest expense and $3.6 million decrease in gain on sale of loans.
Net Interest Income. Net interest income increased $7.6 million, or 12%, to $72.0 million for the three months ended June 30, 2022, compared with the three months ended June 30, 2021. The 12% increase reflected a $16.8 million, or 23% increase in interest income from higher yields and average loan balances, partially offset by a $9.2 million increase in interest expense from higher interest rates and average balances of deposits and borrowings. The interest rate spread of 2.90% for the second quarter of 2022 increased 22 basis points compared to 2.68% in the second quarter of 2021.
Our net interest margin increased 28 basis points, to 3.03%, for the three months ended June 30, 2022 from 2.75% for the three months ended June 30, 2021. The increase in net interest margin reflected higher average loan balances at higher average yields.
Interest Income. Interest income increased $16.8 million, or 23%, to $89.3 million for the three months ended June 30, 2022, compared with the three months ended June 30, 2021.
