10 U.S.C. § 233 — Operation and maintenance budget presentation

(a) Identification of baseline amounts in O&M justification documents. Whenever the President's budget for a fiscal year requests a different amount for a Department of Defense operation and maintenance program, project, or activity than the amount actually appropriated for that same item in the current year, the O&M justification documents supporting that budget must identify the current appropriated amount, and state the difference between it and the requested amount — both as a dollar figure and as a percentage. (b) Navy for ship depot maintenance and for intermediate ship maintenance. In the Navy's O&M justification documents for any fiscal year, the amounts requested for ship depot maintenance and the amounts requested for intermediate ship maintenance must each be identified and kept distinct from one another. (c) Definitions. (1) "O&M justification documents" means the Department of Defense's budget justification documents for operation-and-maintenance accounts, submitted to the congressional defense committees to support the Department's part of the President's budget for a fiscal year. (2) "President's budget" means the budget the President submits to Congress under section 1105 of title 31 for a fiscal year. (3) "Current year" means the fiscal year during which the President's budget is submitted.
