Thanks for your responses; please let me restate. The exception 13 CFR 121.404(g)(3) was triggered and the firm rerepresented itself as other than small at the 5th year. It then, either through a novation or declining revenues/staff, becomes small. Then, a task order solicitation requires firms to represent their size using criteria similar to 52.219-1 at the time of task order submission, and does not question the offeror's status on the IDIQ contract. Is the offeror eligable for task order set-aside even though the Government should not be taking small business credit per FAR 19.301-2(d)?
Navy_Contracting_4, I only question your "wouldn't it be false" question because the Government shouldn't be taking credit per FAR 19.301-2(d)? Same issue with the novation, if I certify as small then large them small, 19.301-2(d) still doesn't allow the Government credit based on my literal interpretation of this sentence.
BTW, I don't think FAR 19.301-3 applies because the its limited to "before contract award", though I've always found this to be unclear as to when and how the Goernment could take credit for the small busienss award.
