Analyst · Citi Global Markets
Good morning, everyone, and thank you for joining us today. I'll begin today's call with an overview of results for the quarter followed by an update on our noncore assets, which we are pleased to say have been reduced to a nominal amount. Following my remarks, Tanner will discuss the market environment, review our investment activity, provide an update on Merx and discuss the portfolio's credit quality. Lastly, Greg will review our financial results in detail. We'll then open up the call to questions.
Beginning with our results. Net investment income for the quarter was $0.42, which reflects a slight increase in interest income and strong fee and prepayment income. We recorded a net gain on our corporate lending portfolio, which continues to perform well. Overall, we had a net loss in our portfolio, primarily driven by a net loss on Merx due to exposure to Russia, which Tanner will discuss later during the call and on our remaining shipping investment, which was adjusted based on the expected net proceeds from a pending sale. Given the total return feature in our incentive fee structure and the net loss in our portfolio, incentive fees significantly declined quarter-over-quarter. We ended the period with net asset value per share of $15.79.
Shifting to an update of our portfolio. We continue to successfully execute our strategy of investing in senior secured first lien middle market loans and also continue to make substantial progress reducing noncore assets with the receipt of significant cash proceeds from the repayment of noncore assets. During fiscal 2022, proceeds from the sale of noncore assets totaled $47 million, including $32 million in the March quarter. At the end of March, noncore assets totaled $135 million at fair value and represented about 5% of the portfolio. Post quarter end, we have received approximately $6 million of additional proceeds from noncore assets, and we have good visibility into additional repayments in the coming quarters as we are in exclusive negotiations on 2 of our [ names ], which will reduce our noncore exposure to approximately 3% of the portfolio.
I will now provide some color on these sales. Beginning with our shipping investments during the March quarter, the Dynamic Product Tankers closed on the sale of 4 vessels in its suite, generating approximately $28 million of cash in the quarter. You will see a $3.1 million position in Dynamic at the end of March on our scheduled investment relates to net working capital adjustments. Since the end of the quarter, we have received a $1.4 million payment from Dynamic and expect to receive the remaining balance by the end of June, at which time we will have fully exited that investment. We're in the process of selling the vessels of MC and our other shipping investment. The fair value of our investment in MC was $34.3 million at the end of March, reflecting the anticipated exit values from 2 proposed transactions, which will be supported by a small amount of seller financing. We have signed a PSA on 2 vessels, which we expect to close by the end of June, and we anticipate closing on the sale of remaining vessels in the MC fleet in the September quarter.
Moving to our oil and gas investments. We have some positive developments to announce. First, we signed a letter of intent to sell our investment in Spotted Hawk, and we expect the purchase agreement to be finalized in the next couple of weeks. We expect [indiscernible] in the next few months, which we estimate will generate debt proceeds at or above our $30.1 million mark at the end of March. The demand for this asset is high and there are multiple interested parties. Glacier, another oil and gas position is also benefiting from the increase in the price of oil. At the end of March, the fair value of the investment in Glacier was [ $62 ] million. The company continues to perform well as AINV received a $3.5 million paydown during the quarter and also wrote up the investment by $3.6 million. Post quarter end, Glacier paid AINV an additional $4.5 million on its outstanding obligations, which represented approximately 73% of the fair value position at the end of March.
Pro forma for post quarter end activity, including pending sales, noncore assets totaled approximately $63 million, representing approximately 3% of the total portfolio at fair value. We are focused on monetizing the remaining noncore assets and are cautiously optimistic that there may be some upside in some of the remaining noncore positions. Our $42 million investment in Carbonfree Chemicals makes up the vast majority of the remaining noncore assets. As a reminder, our investment in Carbonfree consists of an investment in the company's proprietary carbon capture technologies and the company's chemical plant. Carbonfree is benefiting from strong interest in carbon capture, utilization and storage as a part of broader ESG trends.
Going forward, we do not intend to break out noncore assets as a separate category in our supplemental reporting. Of course, we will continue to disclose the detail of each investment on our scheduled investments, and we'll provide updates each quarter. We also continue to reduce our exposure to junior capital positions and received $7 million of second lien corporate loan paydowns during the quarter.
Shifting gears a bit, let me take a minute to remind everyone about the construction of our corporate lending portfolio given the current operating environment, which is characterized by elevated inflation, higher interest rates, higher energy prices and other geopolitical factors. Similar to our positioning heading into the pandemic, we have built what we believe to be a well-diversified corporate lending portfolio of true first lien floating rate loans invested in less cyclical industries. Our corporate revenue portfolio is 94% first lien with weighted average attachment point of 0.2x, a key metric, which demonstrates that we are truly invested at the most senior level of the capital structure. Additionally, 87% of the corporate lending portfolio is sponsor backed, which means these companies have financial and operational support from the financial sponsors who own it. We feel very good about the ability of our corporate lending portfolio to withstand potential economic headwinds.
In terms of new opportunities, we believe AINV's ability to invest in loans originated by MidCap Financial is one of our most significant competitive advantages. In addition to cash flow loans to middle-market sponsor-backed companies, MidCap's product offering includes life sciences lending, asset-based lending, lender finance and franchise finance, products which are typically less competitive to have a lower correlation with the broader credit markets. At the end of March, these specialty products totaled approximately $340 million, representing about 16% of the AINV's corporate lending portfolio at fair value.
Turning to our distribution for the quarter. The Board has declared a base distribution of $0.31 per share and a supplemental distribution of $0.05 per share for a total distribution of $0.36 per share, consistent with NII for the March quarter, adjusted for a normal level of incentive fees. Both distributions are payable on July 7, 2022, to shareholders of record as of June 16, 2022.
With that, I'll turn the call over to Tanner to discuss the market environment and our investment activity.
