Vesting for rehired employees after partial plan termination

[taxllm]

Due to economic conditions there was a partial plan termination in 2008. At the time of the partial plan termination the affected participants were 100% vested. Some of the affected participants that were terminated are now rehired. Are the affected participants subject to the vesting schedule for employer contributions made after the terminated employees are rehired? That is, are the rehired employees 100% vested on the employer contributions made after the date of rehire or are they subject to the vesting schedule provided in the plan document?

The plan's vesting schedule applies to benefits accrued after rehire.
