Errol:

I will be performing the following 2 tasks tomorrow morning in the production database.
You have already approved of both of these tasks - please let me know if you do not
want me to do this tomorrow.

(1) Remove Jul. 5 and Nov. 28/29 2002 as business days from the NYMEX calendar. On completion of this, all the
holidays will have been removed as business days for 2002.

(2) The day after Thanksgiving used to be a business day until 1998 - it has became a holiday since then.
The futures/options expiration dates for Dec. NG NYMEX contracts were calculated with the day after Thanksgiving
as a business day. I will correct these dates for 2002 (from Nov. 26 to Nov. 25 for futures, from Nov. 25 to Nov. 22 for
options) and update the affected NX1, NX3 and NXB2 deals. (There will be a slight effect on your books.)
(We have been performing this task once a year since 1998.)

Please let me know if you have any concerns/questions.

Thanks,
Jeremy

Truong was supposed to check with Errol before we do this in prod. - do you know
if he got approval?

I have done this in devel. with Truong - we can do this together in stage/prod.

Thanks.

Francis/Truong:

Another issue we have to deal with yearly is the day after Thanksgiving - it was not a NYMEX holiday until 1998, and it seems like
it will be a holiday next year.

The NG futures and options termination dates are stored in ermt as the 3rd business day from the end of the month and the 4th
business day respectively. For November, this was calculated with the day after Thanksgiving as a business day - these 2 dates may
need to change now that it is a holiday.

We have a number of complicated scripts that updates the termination dates, the deals and the averaging dates that we run once
a year to fix this problem.

I will need to work with you and Truong this week to do this for 2002 - let me setup the scripts and then I will go through with the 2
of you and do the fix together.

Truong:

Please check with Errol:

(1) The day after Thanksgiving 2002 is a NYMEX holiday.

(2) As such, the futures termination date for Dec. 2002 is Nov. 25, and not Nov. 26 (NX1 date).

(3) The options termination date for Dec. 2002 is Nov. 22, and not Nov. 25.

Thanks.

Francis:

(1) Truong has been in charge of putting in holidays into the database (actually we don't store holidays, we remove them
as business days), and Cecilia has been in charge of creating new calendars in the database - these 2 duties should
probably be done by 1 person with a backup.

(2) 5 active calendars are currently defined, with the user group owner identified:
NYMEX - Gas (with EGM and EIM also)
IPE - EGM (Houston)
SIMEX - EGM (Singapore)
TOCOM (Tokyo) - EGM (Singapore)
NYMEX + IPE (this is an intersection of business days - i.e. a holiday in either exchange is a holiday in this calendar.) - EGM (Houston)

(3) We usually remove holidays as business days 1 year at a time, a few weeks before the start of the next year, by getting
the list of holidays from our user group, as identified above. We then get approval from them as to the day they want us to
do it.

(4) A number of holidays in the future years have already been removed as business days due to user requests - Truong has the list.

(5) Please ensure that this process is continued.

Thanks,
Jeremy
