Judy... re: SLB options 'net change' The bid is 10 1/4, ask is 11 on the Jan 2000's. The 'change' is based on the last trade which is 10 i.e. the options upticked after the last trade. Usually best to monitor change-in-bid/ask rather than change-in-last-price with volumes like these. Bid Ask Last Vol 6 6 1/2 Jan 99 5 7/8 10 10 1/4 11 Jan 00 10 26 14 1/8 14 7/8 Jan 01 14 1/2 3 Unfortunately, I don't know of a source for the bid/ask as of end of Thursday so we don't know if the price used to determine the net change was inside or outside the then current bid/ask. The year-to-year changes in bid/asks don't appear unreasonable.

Judy did they all trade. Often people look to the last sale and not hte bid ask. The last sale might have been days ago in leaps and not indicative of the true quote. Check it out. Tom d
