Subject: P+ spread options

Jeff,

We are reviewing the P+ spread option book. One item of note is that the
correlations used to book the spread options have dropped significantly from
what was being used a year ago (see charts below). I also remember that
John Mee was using even higher correlations when he ran this book. In fact
he wanted to book options with a correlation of 1.0, but our model would not
allow it, so he was using 0.999.

We are currently calculating historical correlations for you as well. If
you want, Vince and I can review this with you at the end of the day. Just
let me know what time would be convenient.
