Table of Contents with corrections

1 Estimating Credit Scores with Logit.

2 The Structural Approach to Default Prediction and Valuation. 02merton.xls

Column G in sheet T1 of "02merton.xls" reads
(B4+C4*EXP(-D4*1)*NORMSDIST(BSd1(F4,C4,1,D4,I$4))-I$4)/NORMSDIST(BSd1(F4,C4,1,D4,I$4))
and should read
(B4+C4*EXP(-D4*1)*NORMSDIST(BSd1(F4,C4,1,D4,I$4)-I$4))/NORMSDIST(BSd1(F4,C4,1,D4,I$4))
