Challenges and importance of modeling LGD How to construct a database Preparation steps for modeling Modeling approaches Increasing the dataset size Conclusion
2
Modeling in a qualitative world
Wines are the best when grapes are ripe (lower acidity) and
the juice is concentrated
In hot summers the grapes get ripe and with low rain fall
they get more concentrated
Regression analysis by Orley Ashenfelter:
Wine quality (auction price) = 12.145 + 0.00117 winter
rainfall + 0.0614 average growing season temperature – 0.00386 harvest rain
Reaction by the most famous wine critics:
“Somewhere between violent and hysterical” “An absolute sham” “It’s really a Neanderthal way of looking at wine” “I’d hate to be invited to his house to drink wine”

LGD modeling is important
LGD’s are equally as important as defaults The supervisor requires LGD and downturn LGD (Very
Challenging)
There is more uncertainty around LGD’s than PD’s

Uncertainty about LGD estimates
Based on an European SME securitization end of 2009.

PECDC LGD observations

Predictor variables
Bank loans have many different appearances:
cash and non cash utilization repayment seniority collateral jurisdiction
Predictor variables selection:
Literature Observations in the database
11
LGD: Two stochastic variables
LGD = EAD -/ - recovery cash flows EAD is driven by
facility type covenants bank behavior
managing down the exposure triggering the default
Recovery cash flows
quality of the obligor Seniority jurisdiction collateral
12
Interpretation of the database
Are secured loans the same as unsecured loans plus
collateral?
What is the impact of covenants? What is driving the recovery and where does the cash come
from?
Is there a difference in default registration between i.e.
secured and subordinated loans?
13
Are some loans more in default?
14
Time Company Value
Restructuring for subordinated Restructuring for secured loans Bankruptcy
Modeling approach
LGD modeling for
before default after default
Approach
Linear model violates normal and homoskedastic residuals Log-linear model (NIBC) Dealing with the Bimodal distribution of LGD’s (NIBC)
Two-step approach
- Logistic model
- Loss Given Loss Model
Survival Analysis in Time (Danske Bank)
Alternatives
Assuming a Beta distribution
15
Two step approach
16
Loss | Default Prob Loss | Loss Prob
Modeling steps
Manipulating the predictor variables
Perform calculations Relabeling/ grouping of data fields Changing data fields into a reusable formats (empty or zero) Capping LGD’s between 0% and 150% Continuous variables, discrete variables and dummy variables
Creation of a Reference Dataset
Exclusion of small exposures Exclusion of over and underpayments Exclusion of biased years
Regressions
Backward elimination based on lack of significance and multi collineairity
Analysis of explanatory power and correlation with observed LGD’s

Using unresolved defaults to increase the data base
19
Conclusion
Modeling LGD is difficult What is needed?
Proper understanding of the lending business Representative, large, unbiased and detailed datasets Increase the dataset by using unresolved defaults
We need more research and data collection to get to the
LGD models we ideally want.
