  • Not an instance

Editorial commentary

Encumbrances reflect funds that are formally committed but not yet expended. They are critical to accurate post-award management because cash-basis reporting can otherwise overstate remaining funds. Standard encumbrance categories include open purchase orders, payroll commitments through the end of the budget period, and unspent portions of executed subawards. Available balance is calculated as: budget minus expended minus encumbered. Encumbrance accounting is mandated by Uniform Guidance for federal awards.
