Thank you, Craig, and good afternoon, everyone. We kicked off the year with solid momentum, fueled by the strategic deployment of capital, particularly into new and follow-on debt investments. This approach has consistently delivered results over the past years and evidences our strong performance in the first quarter of 2024.
The initial 3 months were dynamic within our portfolio characterized by these new and follow-on investments, certain equity sales and portfolio repayments. This activity does underscore the strength and agility of our investment approach. Moreover, seizing upon favorable marketing conditions -- rather market conditions, we realized $3.5 million from the sale of our ACV Auction stock. This strategic exit in conjunction with the prudent utilization of our credit facility has enabled us to deploy over $10 million during the quarter, fortifying the potential yield in the future of our portfolio and the strengthening dividends. Noteworthy is the evolution of our debt portfolio, which now represents 70% of our total mix, up from 64% at the close of 2023 and 56% at the end of 2022. This strategic shift has driven the 12% growth in total investment income for the quarter.
This strong performance translated into tangible benefits for our shareholders as evidenced on Slide 4. Year-to-date, we have declared total dividends of $0.54 per share. This includes a cash dividend of $0.25 per share for the first quarter. And just last week, on May 8, we increased our regularly quarterly cash dividend for the second quarter by $0.04 per share, marking a 16% increase and is now at $0.29 per share. This dividend increase reflects not only the strength and stability of our business operations and its portfolio but our consistent and confident abilities to execute in the future trajectory of the company. We firmly believe that our deal flow and unique marketing position will continue to support future dividends. At quarter end, having put our capital to work and distributing $645,000 in cash dividends to the shareholders, we still had approximately $11 million in total availability including our cash on hand, line of credit availability and our highly liquid publicly traded securities.
If you turn to Slide 5, you can see our portfolio mix between debt and equity and the changes during the recent quarter. Our portfolio consisted of investments with a fair value of $82.8 million across 30 portfolio businesses. This was up $5.6 million rather, a net basis or 7% from the year-end 2023 and reflected these new and follow-on investments in valuation adjustments in multiple portfolio companies. These were partially offset by our sale of ACV Auctions stock and other portfolio company loan repayments. The portfolio comprised approximately 70% in debt investments, as I priorly noted -- previously noted rather, which have an annualized weighted average yield of 13.7% which includes PIK or payment in kind interest. The remaining mix was comprised 25% in equity investments in private companies and 5% in publicly traded securities consisting of our other BDC investments. During the first quarter, we completed 1 follow-on and 2 new investments. These transactions are highlighted on Slide 6.
The larger investment was a debt investment totaling $5.5 million into Mattison Avenue Holdings. They had previously repaid their $1.9 million loan to Rand also during the quarter. This debt instrument will carry a rate of 14%, including PIK interest. Mattison Avenue is based out of Texas and provides upscale salon spaces for lease. The second was a new investment of $3.2 million made with Mountain Regional Equipment Solutions or MRES. That consisted of a $3 million term loan at 14% and a $205,000 equity investment. MRES is based out of Utah and supplies automated lubrication systems, active and passive safety systems and maintenance products designed for the mobile heavy equipment industry.
The follow-on investment during the quarter was $1.8 million into Seybert's Billiards Corporation, a billiard supply company based out of Michigan. With this investment, our total debt and equity investment in Seybert's increased to a fair value of $7.8 million at quarter end. The bottom half of the slide highlights the notable exits and repayments from the quarter, including the sale of the stock of ACV Auctions. We have determined an appropriate time to make an exit within our investment portfolio and this is often just as critical as making the initial investment.
The shares of ACV were sold at an average price of $18.02 per share. And the sales of the 194,000 shares did result in a realized gain of $3.5 million. I should highlight that during the prior quarter, we had ACV stock valued or that is rather unrealized appreciation for approximately $2.9 million. And with the sale, we have now monetized that prior appreciation. During the quarter, we also received $687,000 principal loan repayment from PressurePro, which left our total fair value of debt and equity investment at $2.4 million into this portfolio company.
The chart presented on Slide 7, offer a visual depiction of the diversity within our portfolio and the evolving landscape of industry allocation over the past quarter. Against the backdrop of recent investments as well as adjustments in fair value, our industry composition saw notable changes during the quarter. Sectors such as Professional Services, Consumer Products, and Distribution witnessed growth. On the other end, we observed declines in the representation of the manufacturing and software industries. Overall, we continue to value this diversity of our industry mix. The diverse spectrum of sectors across our entire portfolio serves as a testament to our strategic approach, ensuring resilience and mitigating risk in our investment efforts.
Slide 8 lists our top 5 portfolio companies at quarter end. Tilson continues to remain the largest fair value investment at well over $10.6 million or 13% of our total portfolio. Seybert's moved up to #2 following our recent investment and Mattison Avenue also moved to the fourth ranking following our investment. Overall, these top 5 represent 44% of our total portfolio at quarter end.
With that, I'll turn it over to Margaret for a further review of our financials.
