Camy, quite simple. the bean counter were SECOND to the party. The first in were the sales people and most of them ASSUME that the company is viable. Look at the IMDS website. Do you see any banner that says "WE STOLE THE IRS TRUST FUND MONEY AND THEY HAVE A LIEN AGAINST US"? or "WE'RE 5.5 MILLION IN DEBT"? or "WE'RE IN A TOXIC DEATH SPIRAL FOR FINANCING"?
No, it's all fluff and how great things are. Pure propaganda. It takes the beanies to look deeper and to their DD and that is done through the SEC filings.
