Updated from 12:50 a.m. EDTGoldman Sachs ( GS) said Monday it raised its fifth dedicated private equity secondaries fund, GS Vintage Fund V, with about $5.5 billion in capital commitments. Limited partners in the fund include existing and new institutional and private investors throughout the Americas, Europe, Asia and Australia, Goldman said in a press release Monday. The news from Goldman confirms a report in the Wall Street Journal that the investment bank was nearing completion of $5.5 billion in investor commitments for a new fund to buy private-equity investments at a discount on the secondary market. The GS Vintage Fund V would be the largest secondary fund ever raised, according to the Journal. Goldman has become one of the leaders in the secondary-buyout area, the newspaper reports, adding the investment bank has raised four previous funds totaling about $6 billion. The Journal reports the market for such limited-partnership interests has become a hot sector of the private-equity market, as some pension funds and endowments scramble to reduce their exposure to the sector. Sales of such interests are occurring at discounted prices of 50% to 70% or more from face value, the Journal reports, citing private-equity executives. One reason for the discount is that such partnership interests often include the obligation to put up more cash for future investments, according to the Journal.
