In 2000, Ford motor company spun off a subsidiary named Visteon, as well as several employees that went to work with Visteon. Visteon transferred some facilities, as well as these same employees, back to Ford in 2006. The employees were classified as re-hired rather than reinstated. When these employees were later provided with severance pay pursuant to a reduction in force in 2008, did Ford violate ERISA by classifying the employees as rehired rather than reinstated
