The City shall reimburse the participant from the participant’s dependent care assistance account for dependent care expenses incurred during the plan year for which the participant submits documentation in accordance with Section 4.42.501. The City shall make such reimbursements once each month. No reimbursement or payment under this Section 4.42.502 of expenses incurred during a plan year shall at any time exceed the balance of the participant’s dependent care assistance account for the plan year at the time of the reimbursement or payment. The amount of any dependent care expenses not reimbursed or paid as a result of the preceding sentence shall be carried over and reimbursed or paid only if and when the balance in such account permits such reimbursement or payment. In no event, however, will any reimbursement or payment be made for expenses which were incurred prior to the date the participant’s participation in the plan commenced for such plan year.
