It's worth mentioning since the SEC had to make an example out of someone:
The SEC alleges that American Growth Funding II LLC and Ralph Johnson promised investors 12-percent annual returns and falsely claimed its financial statements were being audited each year. AGF II, which raises capital from investors to provide loans to businesses, also made misrepresentations in offering documents about its management and concealed details about deteriorating loan values that could imperil full payment of the promised returns to investors. The company’s placement agent Portfolio Advisors Alliance and its owner Howard Allen and president Kerri Wasserman allegedly knew the offering documents were inaccurate yet continued using them to solicit sales of AGF II securities.
To Ralph Johson's credit, it's not like he didn't try to retain an audit firm. Here are some of the highlights from the SEC's complaint.
