With the Part 2 Application, bidders must submit their executed Pre-Auction Letters of Credit. The EDCs do not provide courtesy reviews of draft documents. Bidders must use the final version of the Pre-Auction Letter of Credit or include only modifications that are acceptable to the EDCs on an optional basis as posted to the BGS Auction website. The list of modifications acceptable to the EDCs on an optional basis is available in the document entitled “Final Acceptable Modifications to Pre-Auction Letter of Credit” posted to the Application Process page of the “bidder info” tab.
