Adverse selection refers to an economic process in which undesirable outcomes occur when parties to a transaction have asymmetric information.
___ ___occurs after an economic transaction is completed and arises when one party to a transaction changes its behavior and the other party bears the consequences.

Recovery Rate Equation
PV of sum to be recovered / Exposure at Default (EAD)
Loss Given Default (LGD) Equation
Exposure at Default (1 - Recovery Rate)
Expected loss given credit risk equation
Loss Given Default (LGD) x Probability of Default (PD)
=
Exposure at Default (EAD) * (1 - Recovery Rate) * PD
The ___ approach to modeling credit risk assumes an explicit relationship between a firm’s capital structure and default, and describes the value of a firm’s assets as being equal to the value of its equity plus the value of its debt.
The structural approach to modeling credit risk assumes an explicit relationship between a firm’s capital structure and default, and describes the value of a firm’s assets as being equal to the value of its equity plus the value of its debt.
Under the structural approach, the firm’s equity is considered a ___ ___on its assets, with a strike price equal the face value of its ___due at ___date.
Under the structural approach, the firm’s equity is considered a call option on its assets, with a strike price equal the face value of its debt due at exercise date.
The ___-___approach to modeling credit risk models default as an exogenous event driven by a random signal.
The reduced-form approach to modeling credit risk models default as an exogenous event driven by a random signal.
The ___ approach to modeling credit risk involves examining the financial data of companies that have defaulted to try and understand their credit risk.
The empirical approach to modeling credit risk involves examining the financial data of companies that have defaulted to try and understand their credit risk.
The best known structural credit risk model is the ___ model.
The best known structural credit risk model is the Merton model.
Murton Model Equation
Assets = Debt + Equity
The Murton Model assumes that default occurs at ___. It also assumes that ___is costless, ___and ___can be traded without friction and that debt is a ___-___bond.
The Murton Model assumes that default occurs at maturity. It also assumes that bankruptcy is costless, debt and equity can be traded without friction and that debt is a zero-coupon bond.
Equity in a merton model equation
E = max(A - K, 0)
E = Equity
A = Assets
K = Strike
Debt in a merton model equation
D = K - max(K - A, 0)
D = Debt
K = Strike
A = Assets

d = what in black scholes model
Probability of Default in the Merton Model Equation
Value of Zero Coupon Debt in Merton Model (equation)
Spread in Merton Model (Equation)

- It is not successful as explaining the ___ ___ on ___-___ securities
The Merton model has several shortcomings:
- It’s model’s parameters are not readily observable
- It is not successful as explaining the credit spread on short-term securities

The Merton model has four important properties:

The ___ model is a structural credit risk model that estimates the credit risk of debt by considering the loan repayment incentive problem from the perspective of the borrowing firm’s equity holders.
The KMV model is a structural credit risk model that estimates the credit risk of debt by considering the loan repayment incentive problem from the perspective of the borrowing firm’s equity holders.

Relationship between volatility a firm’s assets and equity according to KMV model (equation)
The ___ model’s default trigger is the face value of the zero coupon bond.
The merton model’s default trigger is the face value of the zero coupon bond.
The ___ model’s default trigger is based on a weighted average of face values of short-term and long-term debt.
The KMV model’s default trigger is based on a weighted average of face values of short-term and long-term debt.
The ___ to ___refers to the number of standard deviations that a firm’s assets must lose to decline in value to the default trigger.
The distance to default refers to the number of standard deviations that a firm’s assets must lose to decline in value to the default trigger.
Distance to Default Equation
The KMV model calculates the ___ ___ ___ empirically as the ratio of the percentage of firms in a database that defaulted within one year when their asset values placed them n standard deviations away from the default at the start of the year relative to the total population of firms that were n standard deviations away from default.
The KMV model calculates the expected default frequency empirically as the ratio of the percentage of firms in a database that defaulted within one year when their asset values placed them n standard deviations away from the default at the start of the year relative to the total population of firms that were n standard deviations away from default.
