  3. Obligation authority is a limit placed on federal-aid highway and highway safety construction program obligations to act as a ceiling on the obligation of funds that can be made within a specified time period, usually the federal fiscal year, October 1 through September 30, regardless of the year in which the funds were apportioned. This limit is imposed by the Federal Highway Administration in order to control the highway program spending in response to economic and budgetary conditions.
  4. Design Division
Anchor: #i1005991
Obligations are commitments made by federal agencies to pay out money in the future, as distinct from the actual payments, which are “outlays.” Generally, obligations are incurred after the enactment of budget authority. However, since budget authority in many highway programs is in the form of contract authority, obligations in these cases are permitted to be incurred immediately after apportionment or allocation. The obligations are for the federal share of the estimated full cost of each project at the time it is approved, regardless of when the actual payments are made or the expected time of project completion.
