Initial and Subsequent Eligibility Computation Periods. If the Plan requires one Year of Service for eligibility and an Employee does not complete one Year of Service during the Initial Eligibility Computation Period, the Plan measures Subsequent Eligibility Computation Periods in accordance with the Employer's election in its Adoption Agreement. If the Plan measures Subsequent Eligibility Computation Periods on a Plan Year basis, an Employee who receives credit for the required number of Hours of Service during the Initial Eligibility Computation Period and also during the first applicable Plan Year receives credit for two Years of Service under Article II.
