An encumbrance is an estimate of the salary and benefit expense which will occur for the future. Salary and benefit expense encumbrances are generated semi-monthly. Negative encumbrances (liquidations) reverse the prior semi-monthly period encumbrance by changing (reversing) the sign. Encumbrances are only generated for salaried appointments.
An encumbrance is a reservation of budget funds that are set aside to make sure that actual expenditures do not exceed the available budget.
