	This release is based on the Stage release 4.2.0s2 issued on 09/27/2001 with the following changes:

	New Features:

Changes Affecting All:

Asian strip.  

	Part I:

Average period more than 1:  curve values are used to calculate the average settlement price for the settled days when settlement price is not yet available.

Average period equals 1: removed a change ( for average period greater than 1 ) that had unexpectedly increased the 2nd order.

Part II:

For Asian option consisting of more than one average period:

Updated the option library so that results tie up with the latest Exotica,  theta in particular.
Prior day results tie up.
A fix on curve shift approved by the Research Group, 2nd order is reasonable now.
Fixed the problem that the option value in front end did not match ad-hoc.
Fixed the value at risk table so that RAC can match ad-hoc.
Fixed the interest rate for option evaluation as that of the expiry date. Fixed the volatility smile.

Index option.

	Part I:

Enable scenario sensitivity calculation for index option.  ( Feature was available in 4.2.0s1.)

Part II:

This version handles the case when the delivery point is in a different region from the settlement price region.    Two things that are not handled in this version : cases when delivery point is in the same region as the settlement price region; and sensitivity scenarios.

Post ID is now stored in the adhoc table.


Changes Affecting Australia:

Curve read even if it is a holiday.


	Please let us know if you have any questions or concerns.

	Thanks,


Norman.
