setasides and changed status

Situation: Business is small for revenue based NAICS code XXXXXX on September 29, 2010. Business's fiscal year ends September 30, 2010. Business submits proposal for contract setaside for small businesses in NAICS code XXXXXX on October 15, 2010, and certifies it is small.

October 30, 2010, business closes its books for previous FY and learns that its revenues for 2010, averaged with previous two years, exceed size standard for NAICS XXXXXX.

Thus, business was not small when it submitted its proposal and it incorrectly certified.

Business is awarded contract on November 1, 2010.

Business accepts contract, and there are no size protests.

No false claim for the certification on Ocotber 15. T/F?

False claim for invoices against the contract. T/F?

Other consequences of business accepting/billing the contract?

Thanks in advance.
