Stake is Sold: A health care company in Burlingame said Wednesday that it has bought a 60% interest in South Coast Rehabilitation Services in Laguna Hills, which supplies therapy services for nursing homes.

Vivra Inc. said it was interested in South Coast because it fits with its strategy of investing in companies that have an edge over competitors. South Coast has developed a special software that enables it to improve its service, said Kent Thiry, Vivra’s chief executive officer.

South Coast’s management keeps ownership of the remaining 40% of the company. Other terms of the deal were not disclosed.
