Availability

From Open Risk Manual

Definition

Availability. Property of being accessible and usable on demand by an authorised entity.

It is a metric which measures the percentage, normally computed over a periodical basis (such as a month) and net of planned or unplanned service downtimes of service coverage.

In procurement finance, it is the amount of money that is available for drawing to the assignor. This would be the value of all approved receivables multiplied by the pre-agreed prepayment percentage less any amounts already paid to the assignor.
