The DEPOTS Act authorizes the Secretary of Defense to write off certain accounting costs and internal debts carried by military depots and arsenals when capital equipment no longer generates revenue due to government-directed mission changes. The bill allows the Defense Department to eliminate depreciation charges and internal debt associated with these facilities from their financial accounts, helping streamline accounting practices across military branches. This authority applies only to internal Department of Defense accounts and does not affect payments owed to private contractors. The Secretary of Defense can delegate this authority to individual military department secretaries. The legislation aims to improve financial planning and throughput at military maintenance and manufacturing facilities by clearing legacy accounting obligations tied to outdated or repurposed equipment.
