Expected Loss (EL)
Expected Loss (EL) is the credit cost embedded in a bond's spread: EL = PD × LGD, where PD is the annualized probability of default and LGD is Loss Given Default (1 − Recovery Rate). For example, a bond with 2% annual PD and 60% LGD has EL = 120 bp. Under the simplified CFA framework, spread ≈ PD × LGD = EL — meaning the spread compensates for exactly the expected credit loss. In practice, spreads also include a liquidity premium and a credit risk premium (compensation for volatility of default losses), so market spreads typically exceed pure EL. EL is the starting point for credit analysis: if a bond yields 150bp over Treasuries but EL is only 80bp, the excess 70bp is compensation for uncertainty and liquidity. Note on this panel: PD here is back-solved from the market spread (PD = spread / LGD), so EL ends up identically equal to the spread by construction (the credit-triangle identity). To see the gap between market pricing and rating-implied fundamentals, use the Rich / Cheap row, which compares the market spread against the rating-implied spread from Damodaran's synthetic rating table.
Default Probability (PD)
Annualized probability of issuer default, implied from credit spread and assumed recovery rate.
LGD (Loss Given Default)
The fraction of exposure lost if the issuer defaults — equals 1 minus the recovery rate.
Recovery Rate
Percentage of par value recovered by bondholders if the issuer defaults.
Z-Spread (Zero-Volatility Spread)
The constant spread added to every point on the zero curve to discount all cash flows to the bond's market price.
Rich / Cheap
Market spread minus rating-implied fair spread. Positive = cheap (extra premium); negative = rich (paying up).
