The cash transaction closed June 30, 2010.

Founded in 1968 as a janitorial services company, Diversco today employs 3,000 people and is a national provider of outsourced facility services, with a strong manufacturing and industrial client base in the Southeast, Midwest and Mid-Atlantic regions of the United States.
