What is the average recovery rate for senior secured bonds?
Around 50% ## Footnote Senior secured bonds have higher priority in claims during defaults.
26
What is the correlation between recovery rates and default rates during recessionary periods?
Negatively correlated ## Footnote High default rates during recessions coincide with low recovery rates.
27
What is a credit spread?
The extra interest earned on an asset over the risk-free rate for assuming risk ## Footnote Credit spreads for bonds tend to be relatively high.
28
Why do bond holders require a risk premium?
Bonds do not default independently of each other ## Footnote Systematic risk arises when default rates fluctuate significantly.

37
What does a high credit spread indicate?
Increased risk associated with the bond ## Footnote High liquidity risk may also contribute to higher credit spreads.
38
What is the relationship between rating changes and economic cycles?
Downgrades increase during recessions despite ratings being designed to be through-the-cycle ## Footnote Ratings may not always reflect immediate economic conditions.
39
What is one limitation of using external ratings?
External ratings may not always be available ## Footnote This can lead banks to develop their own internal rating systems.
40
How do KMV and Kamakura estimate default probabilities?
Using models that include factors like debt amount, market value of equity, and volatility ## Footnote These models provide point-in-time estimates.
41
