I have a plan with a rehire. Previous employment was 2014-2016. At that time, the participant made deferrals and was 100% vested in profit sharing funds. In 2021, the plan changed profit sharing vesting from immediate to a 3 year cliff vesting. The participant has returned in 2022. The employer agrees that the employee is a plan participant upon rehire, but the employer is questioning the participant's vesting percentage.
Is the participant 100% vested because that is where they were when they left OR
are they 0% vested because they had more than 5 consecutive 1-year breaks in service allowing previous vesting to be ignored (Taking all years with 1,000 hours into account when calculating the 3 years of service for the cliff vesting, they would have credit for 2015 and 2016, but still be at 0% as of 12/31/22)?
