Milwaukee private equity firm Mason Wells has closed its fourth buyout fund with $615 million of investor commitments, which is $65 million more than its original target for the fund. Mason Wells, launched in 1998, focuses on investing in companies with annual revenues of $25 million to $300 million in the consumer packaged goods, engineered products and services, outsourced business services, and packaging materials sectors. The firm’s most recent deals have included selling Paris Presents Inc, a Gurnee, Illinois-based maker and wholesaler of personal care products, in a deal announced in January 2015; and selling Charter Nex Films Inc., a Milton, Wisconsin, maker of packaging films, to U.K. private equity firm Pamplona Capital Management LLP, announced in December 2014. In 2013, Mason Wells Buyout Fund III acquired the medical packaging business of Sealed Air Corp. (NYSE: SEE) of Elmwood Park, N.J., for $125 million. Several other middle market private equity firms have announced fund closings in recent months. In January, Ardian, formerly the private equity group of French insurer Axa, announced it had raised €2.65 billion ($2.88 billion), for its Ardian Infrastructure Fund IV, including $980 million from new investors, to invest in European infrastructure. Also in January, Nautic Partners closed a $900 million fund and Stonepeak Infrastructure Partners reported it had raised a $3.5 billion fund. Forum Capital Partners was Mason Wells’ strategic adviser and placement agent for Buyout Fund IV, and previously served in the same role with the Mason Wells Buyout funds II and III. Investors in Buyout Fund IV included corporate pension plans, foundations, university endowments, family offices, funds of funds and insurance companies.
