Under that definition, roughly 90 percent of the companies in the world are considered 鈥渃losely held,鈥 according to a 2000 study from Copenhagen Business School. 52 percent of Americans work for a 鈥渃losely held鈥 corporation, according to a study from Columbia University.
The three companies in the Hobby Lobby lawsuit are controlled by single families, but that doesn鈥檛 necessarily mean all 鈥渃losely held鈥 companies are family-owned. The distinction also doesn鈥檛 place any clear boundaries on company size or employee count. Examples of giant yet 鈥渃losely held鈥 companies, noted by Justice Ruth Bader Ginsburg, include candymaker Mars Inc., which has about 72,000 employees and makes about $33 billion in annual revenue, and food processor Cargill Inc., which has over 140,000 employees and made about $137 billion in revenue in 2014.
