Subject: "Storage model".

Body: Tom, The Lukens' storage model is very similar to yours. I got a paper from the lead developer Dr. Hugh Li, explaining in significant details about their model. Let us compare notes after you read it. We have both DP approach (mine) and optimization approach (yours). We may combine the advatanges of the two approach into one product, and then we can claim we have the best Storage Model (and sell it if Vince feels like it). Sounds like a plan ? Zimin

Subject: "Citizens Reconciliation".

Body:
Darla, Attached is the final reconciliation for Citizens. This reconciliation is to repay Citizens for volumes we already recouped from LGS Natural Gas Company. We have included in this calculation the premium, transport costs, fuel and the capacity release credit of $.06 which amounts $241,204.73 due Citizens. Citizens would like to receive payment as soon as possible. In future invoices, we will also see an adjustment for LGS (now Woodward Marketing) volumes to prevent these overpayments from happening. Please let me know when Citizens can expect payment and call me if you have any questions. Thanks,
