5-8.3 Effective Dates

The effective date of an administrative change, change order, or other unilateral modification issued by the Postal Service is any effective date established in the contract or, if none, the date of the modification. The effective date of a bilateral modification (such as a supplemental agreement) is any effective date established in the contract or, if none, the date agreement is reached (usually the date signed by the last agreeing party). Modifications issued in connection with previous directions or agreements, such as settlements of the cost of changes, confirmations of terminations, or conversions of terminations for default to terminations for convenience, ordinarily take the effective date of the underlying action. For modifications converting a termination for default to a termination for convenience, the effective date will be the same as the effective date of the termination for default.
