Thanks, Donna.
I'll start with the net interest margin that Johnny referenced in his comments. As we discussed on the January earnings call, we added approximately $500 million in cash through borrowings late in Q4. That cash -- that excess cash affected the Q4 net interest margin by 1-basis-point and the Q1 2024 net interest margin by 10 basis points as we had the cash for a full quarter. Additionally, we had event income in Q1 2024 that accounted for a 2-basis-point increase to the margin. Normalizing for those items, we would have seen a nice 3-basis-point improvement in the margin on a linked-quarter basis.
We continue to closely monitor asset repricing against the increasing cost on the funding side. The yield on loans, excluding the event income improved to 7.34% in Q1 and outpaced the increase in total deposit cost by a couple of basis points. During the quarter, total deposit costs increased 13 basis points to 2.22% while the yield on loans, excluding event income, increased 15 basis points to 7.34%. We will continue to negotiate pricing with core customers as we have been, but we are encouraged to see the pace of increases on the deposit side begin to moderate.
Switching to liquidity and funding. It was great to see an increase in deposits again in Q1 with solid growth from several of the Florida, Texas and Arkansas regions. Total deposits increased $78 million for the quarter. The deposit mix movement was similar to prior quarters as CDs continue to be in focus for the consumer. Noninterest-bearing balances grew by $30 million in Q1 and account for 24.4% of total deposits.
Alternative funding sources remain extremely strong with broker deposits still only comprising 2.2% of liabilities. The loan-to-deposit ratio was in line with the prior quarter standing at 86% as of March 31. On the asset side, in-period loan balances increased $89 million, led by growth from CCFG, Shore along with several individual regions within the community bank markets. On loan originations, as Johnny mentioned, we saw a volume of $954 million in Q1, with approximately 2/3 of the closing volume coming from the community bank regions. Yields on those originations continue to improve with an average coupon of 9.28% in Q1. Payoff volume declining from Q4 was a total of $549 million, which appears to be the lowest level we've seen in nearly 5 years.
Closing, with the previously mentioned strength of our company, all capital ratios remain extremely strong with a tangible common equity ratio of 11.06%, a leverage ratio of 12.3% and a total risk-based capital ratio of 17.9%. We repurchased 1,026,000 shares in Q1 under our repurchase plan, and we've repurchased about $400,000 or so far this month through our 10b5-1 plan. So we continue to be active there.
With that, Donna, I will turn it back over to you.
