Analysis of Expected Loss Components

Correct Definitions:

• Probability of Default (PD): The likelihood that a borrower will default within a specified time horizon (Option B is correct)
• Exposure at Default (EAD): The total value that is exposed to loss at the time of default, typically including both principal and accrued interest
• Loss Given Default (LGD): The percentage of exposure that will be lost if default occurs (also called Loss Rate)

Analysis of Option A:

• Incorrect: Exposure Amount (EA) is NOT the standard deviation of credit losses
• Correct definition: Exposure Amount (EA) is the total amount exposed to loss at the time of default, typically including both principal and outstanding interest payments
• Standard deviation relates to unexpected loss, not exposure amount

Key Clarifications:

• Exposure Amount typically includes outstanding interest payments, not excludes them
• Standard deviation is a measure of dispersion/variability, not the exposure amount itself
• The formula for Expected Loss is: EL = PD × EAD × LGD

Conclusion: Option A contains an inaccurate definition of Exposure Amount, making it the exception among the statements.
