The SF 133 Report on Budget Execution and Budgetary Resources: 

• Fulfills the requirement in 31 U.S.C. 1511–1514 that the President review Federal expenditures at least four times a year.
• Fulfills the requirement in 31 U.S.C. 1554 to report on unliquidated obligations, unobligated balances, canceled balances, and adjustments made to appropriation accounts during the completed fiscal year.
• Allows the monitoring of the status of funds that were apportioned on the SF-132 Apportionment and Reapportionment Schedule and funds that were not apportioned.
• Provides a consistent presentation of information across programs within each agency, and across agencies, which helps program, budget, and accounting staffs to communicate.
• Provides historical reference that can be used to help prepare the President’s Budget, program operating plans, and spend-out rate estimates.
• Provides a basis to determine obligation patterns when programs are required to operate under a continuing resolution.
• Ties an agency’s financial statements to its budget execution. The compilation of an agency’s SF-133s should generally agree with an agency's Statement of Budgetary Resources.
