2 U.S. Code § 622, "The terms “budget outlays” and “outlays” mean, with respect to any fiscal year, expenditures and net lending of funds under budget authority during such year." The Center on Budget and Policy Priorities differentiates the two ways to define government budgets: "Budget authority is how much money Congress allows a federal agency to commit to spend; outlays are how much money actually flows out of the federal Treasury in a given year." In other words, outlays may liquidate obligations that are incurred in previous years and/or may be authorized by previous years' budget authority. For a fuller explanation, see the "Budget Concepts" (PDF) chapter in OMB's Analytical Perspectives, which is released annually as a component of the President's Budget.
verified that the final months of presidential administrations (including January) are accompanied by a substantial increase in regulatory output by executive branch agencies. A presidential year starting in February avoids attributing an outgoing president’s regulatory output in January to the president's successor—allowing for a better understanding of priorities and activities of agencies under different administrations. Additionally, the lengthy proceduralrequirements necessary to finalize regulatory actions make it unlikely that regulatory output from January 20th (Inauguration day) through the end of the month is related to the incoming administration.
A proposed rule, or notice of proposed rulemaking (NPRM) is a document that an agency uses to explain its plans to address a problem or accomplish a goal. All proposed rules must be published in the Federal Register to notify the public and to give them an opportunity to submit comments.
A final rule is a federal administrative regulation that advanced through the proposed rule and public comment stages of the rulemaking process and is published in the Federal Register with a scheduled effective date.
