Thanks, Bob. Good morning, everyone. During the March quarter, total interest income rose $700,000 or 3% to $23.7 million with the increase in average earning assets. The weighted average yield on our interest-bearing portfolio was largely unchanged at 14%.
The investment portfolio weighted average balance increased to $680 million, which was up $23 million or 3.5% compared to the prior quarter. Other income was $300,000 and total investment income rose $800,000 or 3.3% to $24 million for the quarter.
Total expenses rose by $1.9 million as net management fees rose $1 million with lower new deal closing and advisory fee credits and a $700,000 increase in interest expenses from higher bank borrowings. Net investment income for the quarter was $10.8 million, which was a decline of $1.2 million compared to the prior quarter or $0.2475 per share.
The net increase in net assets resulting from operations was $23.6 million or $0.54 per share for the quarter ended March 31, as impacted by the realized and unrealized valuation depreciation covered by Bob earlier.
Moving over to the balance sheet. As of March 31, total assets rose to $812 million, consisting of $792 million in investments at fair value and $20 million in cash and other assets. Liabilities rose of net originations to $380 million as of March 31 and consisted primarily of $254 million in senior notes. And as of the end of the quarter, advances under our $244 million credit facility were $117 million.
As of March 31, net assets rose to $431 million from the prior quarter end with investment appreciation. NAV rose 3% from $9.51 per share as of December 31 to $9.90 per share as of March 31. And subsequent to March 31, as I think most of you are aware, we executed a 1-for-2 reverse stock split, and our shares of common stock -- and as a result, the approximate NAV per share is $19.80, and the ongoing monthly distributions doubled to $0.165 per share per month.
Additionally, after the end of the quarter, we invested $7.3 million in a new proprietary investment, including senior debt and preferred equity. We also received the payoff of our second lien debt investment in Giving Home Health, which included prepayment penalties of $900,000 and a distribution on our warrant position of $2.5 million. We also received the payoff of our second lien debt investment in Gray Matter Systems, which included prepayment fees of $200,000.
With respect to distribution, our monthly distributions to common shareholders of $0.165 per common share were announced for the months of April, May and June, which is an annual run rate of $1.98 per share. The Board will meet into July to determine the monthly distributions to common stockholders for the following quarter.
At the current distribution rate for our common stock, with the common stock price at about $21.77 per share yesterday, the distribution run rate is now producing a yield of about 9.1%. And now I'll turn it back to David to conclude.
