Thanks, Jay. Our GAAP and adjusted results for the quarter as compared to the first quarter of 2023 includes the following. First, related to earnings, adjusted net income of $117 million, which is an 8% decrease from the first quarter of last year, and adjusted earnings per share of $9.28, which is a 4% decrease from the first quarter of last year.
Second, related to collections, a decrease in forecasted collection rates that decreased forecast of net cash flows from our loan portfolio by $31 million or 0.3% compared to stable forecasted collection rates during the first quarter of last year. The increased forecast of net cash flows for our loan portfolio by $9 million or 0.1%.
Also forecasted profitability for consumer loans assigned in 2020 through 2022, that was lower than our estimates at March 31, 2023, due to a decline in forecasted collection rates since the first quarter of 2023, and slower forecasted net cash flow timing during 2023 in the first quarter of 2024. This was primarily a result of a decrease in consumer loan prepayments, which remain at below average levels.
Then related to volume, unit dollar volumes grew 24.1% and 20.2%, respectively, as compared to the first quarter of last year, and the average balance of our loan portfolio is now the largest it has ever been. On a GAAP and adjusted basis, it increased by 12% and 16%, respectively, as compared to the first quarter of last year.
Additionally, an increase in the initial spread on consumer loan assignments to 22% compared to 21% and consumer loans assigned in the first quarter of 2023. Also an increase in our average cost of debt from 5% to 7%, which was primarily due to higher interest rates and a recently completed or extended secured financings and recently issued senior notes coupled with the repayment of older secured financing and senior notes with lower interest rates.
Finally, the decrease in common shares outstanding since the first quarter of 2023 due to stock repurchases and of approximately 728,000 shares or 6% of the shares outstanding as of March 31, 2023.
At this time, Doug Busk, our Chief Treasury Officer; along with Jay and I will take your questions.
