[2] In some accounts in the Budget of the U.S. Government, certain offsetting collections from the public are deducted from disbursements to determine expenditures for some federal programs. These collections are those mandated, by statute, to be applied directly to finance agency expenditures rather than being transferred to the Treasury. For example, the Aviation Insurance Revolving Fund provides funds to support the aviation insurance program authorized under Chapter 443 of title 49, U.S. Code (formerly title XIII of the Federal Aviation Act of 1958). In addition, intra-government transfers, i.e., transfers from one federal account to another, are treated as offsetting collections. Such transfers are also deducted from gross outlays of the receiving federal program or account to determine its expenditures. Expenditures for some federal programs may be negative because of such deductions.
