what is a fair price for bnb, page-25

Page 4-5 of the annual report 2007:

"We recently announced that we have credit approvals and written commitments for the expansion of our corporate debt facility from $2.35Bn to $2.8Bn and the extension of the facility for a further year to April 2011. The number of banks in the facility has been expanded from 20 to 25 and includes the support of the four major Australian trading banks.

All Australian Banks traded weakly today. Did they trade weakly because B&B are about to be announced as a Bad and Doubtful Debt by NAB, ANZ, CBA, WBC and possibly MQG?
