Availability Period: The time period throughout which an appropriation might be encumbered (that is, committed for expenditure), generally specified by the law making the appropriation. When no particular time is given in financial legislation, the period of accessibility is three years. Unless or else provided, Budget Act appropriations are accessible for one year. Though, based on project phase, the capital outlay projects might have up to three years to hinder. An appropriation with the word "without regard to fiscal year" has a limitless period of accessibility and might be encumbered at any time till the funding is tired.
