The actual plan language is in italics:
"Each hour for which he is paid, or entitled to payment, for the performance of duties for the Employer during the applicable period …" (This tracks 2530.200b-2(a)(1). The plan follows the rest of -2(a) as well but this is not relevant to the question.)
"The rules set forth in (b) and (c) of Department of Labor Regulations Section 2530.200b-2, which relate to determining Hours of Service attributable to reasons other than the performance of duties and crediting Hours of Service to particular periods, are hereby incorporated by reference." (Emphasis added.) (This tracks the requirements of 200b-2(f).)
The requirements for vesting are "completion of 1,000 Hours of Service in the computation period", and for the profit-sharing contribution are "completion of 1,000 Hours of Service in the Plan Year."
I am looking at 200b-2(c)(1), (4) and Example 5 and looking for thoughts on whether it can be interpreted to cover a situation where all the duties are performed before the end of the Plan Year but paid after year end in accordance with regular payroll procedures.
