10 U.S.C. § 432 — Use, disposition, and auditing of funds

(a) Use of Funds. A commercial activity set up under this subchapter earns money. That money may be used to pay for necessary and reasonable expenses of running the activity. The law says to spend as little as possible - only what is needed to run the activity safely and securely. Any money left over, beyond what is needed for that purpose, must be deposited into the U.S. Treasury as "miscellaneous receipts." This deposit must happen as often as practical. (b) Audits. (1) The Secretary of Defense must pick one organization inside the Department of Defense to audit these activities. (2) That organization must audit how the money is used and disposed of at least once a year. It must report the results to the congressional defense committees and the congressional intelligence committees (defined in section 437(c) of this title) no later than December 31 each year.
