The likelihood that a borrower will default on their obligation.
Exposure at Default (EAD)
The total value the lender is exposed to when the borrower defaults.
Loss Given Default (LGD)
The percentage of EAD that is not recovered following a default.
Mathematical Formula
The formula for Expected Loss is straightforward yet powerful:
