Once you become eligible under Section 3.2 and, subject to the early termination of your coverage under Section 6.6, you will be covered for a later calendar month if your Hour Bank contains a credit balance of at least 120 hours as of the first day of such month (taking into account hours credited on that day). Except as provided in Section 3.4 (regarding delinquent contributions), 3.6 (regarding disability) and Article IV (regarding Retirees), no coverage will be provided for any portion of a calendar month if your Hour Bank as of the first day of that month does not contain a credit balance of at least 120 hours.
