Century-Fox Corporation's employees are eligible for postretirement health care benefits after both being employed at the end of the year in which age 60 is attained and having worked 20 years. Jason Snyder was hired at the end of 1988 by Century-Fox at age 34 and is expected to retire at the end of 2016 (age 62). His retirement is expected to span five years (unrealistically short in order to simplify calculations).
