What are the retaining periods for the NAVSUP Form 1090 according to NAVSUP P-486?

The retaining periods for the NAVSUP Form 1090, which is involved in the accountability of supplies, are specifically outlined to ensure proper record-keeping and auditing processes. The correct option reflects that the NAVSUP Form 1090 should be retained for the most recent three accounting periods plus the current month. This retention period is designed to provide a comprehensive view of inventory and transactions, allowing for effective management and oversight.

By maintaining records for this duration, supply personnel can easily reference historical data, identify trends, and ensure accuracy in their accounting practices. This comprehensive approach also aids in preparing for audits and inspections since having access to multiple accounting periods allows for thorough examination of supply chain activities. Retention for just the current month, the past month, or even the last year would not provide the necessary detail and context required for effective supply management and could hinder operational assessments.
