Interpreting Ratings 

The options evaluation calculates the value for the put option on the assets of the borrower. Technically, this is the probabilityadjusted loss for all future default scenarios. In other words, the option value is the default cost the lender can anticipate on a statistical basis through exposure to this borrower  statistically, it is the "Expected Loss". Using the wellknown formula
Expected Loss = Probability of Default x Loss Given Default (EL = PDF x LGD)
Knowing both the Expected Loss and the Loss Given Default, we are able to calculate the Probability of Default (PDF) which is independent of our Loss Given Default assumption (see our Financial Technology page for further discussion of default probability calculations). As well as presenting raw numbers, the PDF is translated into a rating by applying the nonlinear rating intervals presented in the graphs below. The figure given is the upper limit for the risk to be classified within that interval. Click here to download the excel version of the charts.






Ratings are based purely on the PDF, they do not take into account company size or other quantitative factors, we provide a purely quantitativebased rating, leaving users to make adjustments based on qualitative factors as they see fit.
