Auction Id: 58 Date: Thursday, January 27, 2005 01:21:36PM Subject: Bid Increment Change At the conclusion of Round 7 today, the smoothing formula used to calculate minimum acceptable bids will be changed as follows: The variable N (minimum percentage increment) will be changed from 0.10 to 0.05. The variable M (maximum percentage increment) will remain the same at 0.30. This change will be reflected in the minimum acceptable bids for Round 8. As a result of this change, minimum acceptable bids will be 5% to 30% higher than standing high bids, instead of the current range of 10% to 30% higher than standing high bids. Please see the Minimum Acceptable Bids and Bid Increments section (pages 30-31) as well as Attachment F of the Auction No. 58 Procedures Public Notice (DA 04-3005, released 9/16/04) for more detailed information.
