TEANECK: Cognizant will buy the health care software company TriZetto for $2.7 billion in cash.

Privately-held TriZetto Corp is based in Englewood, Colorado. The company and its 3,700 workers will join Cognizant's existing health care information technology business, the company said Monday.

The information technology consulting and outsourcing company is expecting the acquisition to significantly accelerate its market position. Health care currently makes up about 26% of Cognizant's revenue.

Company president Gordon Coburn said that the deal will provide an opportunity to integrate across traditional IT services; high-growth businesses such as management consulting, business process services and IT infrastructure services and emerging delivery models.
