NiSoft, a Belfast-based provider of safety management document systems, has been bought by its management in a deal that includes its US subsidiary.

The buy-out was led by chief executive Doug Deardorf, who invested in the transaction alongside private equity firm Crescent Capital.

NiSoft, which provides its systems to power stations and oil refineries around the world, was bought for an undisclosed sum. Deardorf now intends to develop the company with managing director Colin Walsh.

Crescent received legal advice on the terms of its investment by a team from its existing counsel, Mills Selig. The firm was led on the deal by senior solicitor Chris Guy, who was assisted by Andrew Gilliland and Kathryn Walls from its corporate team and property specialist Gary Rocks.

Guy said Mills Selig has acted for Crescent on some of its previous investments: “Crescent’s backing of NiSoft adds another exciting company to its portfolio and gives Doug Deardorf the opportunity to grow the business.”
