> billing month.  For example, the June 2001 charges will be entered on the
> Preliminary Statement for Trade Date 5/31/01.  The SRA charges will then
> be adjusted including penalties and offsets on the Final statement for
> Trade Date 6/30/01 (the last day of each actual billing month) to match
> actual charges calculated based on metered Demand (including Exports). 
> 
> The first charge for June 2001 will appear on the Preliminary Statement
> for Trade Date May 31, 2001.  This Preliminary Statement will publish on
> July 25, 2001.  Adjustments for June 2001 will appear on the Final
> Statement for Trade Date 6/30/01, which will publish on September 12,
> 2001.
