Thanks, Mike. We invested in 3 portfolio companies this quarter, including 2 new portfolio companies. We made first-lien investments in all 3 as well as the preferred equity investment in one of our new portfolio companies. We also had full realizations on 4 investments during the quarter. After quarter end, we funded a delayed draw term loan and had full realizations on 2 investments and a significant partial utilization on the third.
First, our additional investments in existing portfolio of companies. We increased our position in the first-lien loan to Golden Hippo. This has been a stellar performer for us since we made our first investment last year. We also funded under Golden Hippo's revolver during the quarter. The yield on both of these positions is approximately 8.6%. Second, we participated in a club deal for Advanced Solutions International, or ASI. ASI provides CRM software and related functionality to nonprofit organizations, help them manage membership, donations and dues. We made a first-lien investment, which yields approximately 9.4% as well as the preferred equity investment. We are a lender under Deluxe Entertainment Services super priority term loan. This loan was made of the U.S. parent company of our existing portfolio company, Deluxe Toronto Ltd. The super priority term loan bridged Deluxe's liquidity as it progressed through an M&A process to sell the business. This loan is short-dated, we carried upfront and back-end fees, so the yield has been particularly meaningful. After quarter end, we funded a second draw on the super priority term loan. I'm pleased to share with you that last week, Deluxe's sale was completed and the super priority term loan was repaid in full. The short holding period and the aforementioned fees produced a very high positive IRR. We also received a repayment of approximately 70% of our principal on our Deluxe Toronto loan. We expect additional recoveries on this loan over the coming quarters.
Turning to our realizations during the September quarter. We received the full prepayment on the first-lien loan to Endemol early in the third quarter. Our IRR on the Endemol investment, which we have had for approximately 6 years, is 12.9%. We also sold our remaining investment in U.S. Lumber, which produced an IRR of 8.3%. Finally, we were repaid on the term loan D&A for 1888, which are the smallest of the 1888 loans. These 2 loans repaid in accordance with their terms with IRRs of 6.9% on each.
After quarter end, we also received repayment in full for our loan to RPX. Our fully realized IRR was 9%. Finally, after quarter end, we committed to a new portfolio company, Veregy. Veregy is an energy services company providing environmentally efficient upgrades, assistance for the municipal, university, school and hospital markets. Our yield at cost is 7.8%. Using the GICS standard as of September 30, our largest industry concentration was professional services at 12%; followed by construction and engineering at 11.6%; energy, equipment and services of 10.1%; trading companies and distributors at 9.5%; and containers and packaging at 6.4%.
Our portfolio companies are in 24 GICS industries as of quarter end, including our equity and more acquisition. As of September 30, our portfolio company count was 38 versus 38 at June 30. Our portfolio company count is 37 today due to the repayments of RPX and Deluxe's super priority loan and the pending closing of the
Veregy.
I'd now like to turn the call over to Rocco to discuss our financial results.
