Plan entry for a rehire

Plan entry requirements are 6 consecutive months of 83.33 hours per month.  Monthly entry.  Plan is not using 1 year hold out.  Is using Rule of parity.  After initial eligibility computation period, computation period reverts to the plan year.  Plan uses counting of hours method.

Employee(not ever a participant)

DOH - May 2019

Term - Nov 2019

Rehire - May 2021

Term - October 2021

Rehire - April 2022

2019, 2020 and 2021 hours less than 500.  Employee never met the 83.33 hours per month requirement.  But worked over 1000 hours in 2022.  Did work 6 consecutive months of 83.33 hours from April 2022 to December 2022.

When is the employee eligible?  After 2019, does their eligibility computation period revert to the plan year? Do they enter 1-1-23 after having 1000 hours in 2022.  Or do they start new April 2022 and enter November 1, 2022 after meeting the 6 consecutive month/hours requirement?

When you say "reverts to plan year" what does that mean in this case?

What do your service spanning rules says?

Service spanning would not apply.  Plan does not use elapsed time.

Eligibility Service Computation Rules
a.  Eligibility Computation Period switches to Plan Year.
b. Select hours equivalency for eligibility purposes:
i.  None

Without actually reading your document I can't say for sure but my best guess is they entered November 1, 2022 when they met the 6 month rule.

If an employee worked 83.33 hours in April of 2022, the entry date maybe October 1, 2022.

Thank you.  Agree entry date is November 2022.
