Yes.  An entity that receives a Notification of Qualification acquires Qualified Bidder status and retains this status until the end of the Auction Process.  Similarly, an entity that receives a Notification of Registration acquires Registered Bidder status and retains this status until the end of the Auction Process.  There is no possibility to rescind or change this status.  This means that an entity that becomes a Qualified Bidder and that does not submit a Part 2 Application is bound by all the certifications it has made in the Part 1 Application.  Similarly, an entity that becomes a Registered Bidder is bound by all the certifications it has made in the Part 1 and Part 2 Applications, regardless of whether the Registered Bidder subsequently participates in the auction. 

Please review the certifications in the Part 1 and Part 2 Applications for more details and in particular for the time period during which these certifications must remain in effect.
