China isnt just exporting into the U.S. toxic toys or poisonous pet food. Its also exporting toxic companies to invest in -- and not just the problematic reverse mergers that have made headlines recently.

Disclosure Insight looked at five years worth of SEC filings for 27 China-based companies listed here, and looked at 100 different risk factors for each company. A big 24 got negative ratings, says John Gavin, founder and chief executive of Disclosure Insight. Problems included SEC probes, accounting/auditor problems, fights with the boards or executive suites, and other investigative activity. Just eleven were reverse mergers (for names of the companies, see below).

A reverse merger occurs when a company buys a U.S.-listed shell and pours its operations into that entity. That way it not only gets a listing on a U.S. exchange, but it can then raise investor money without having to endure the regulatory scrutiny of an initial public offering.

Problems with reverse mergers have the tort bar up in arms. I flagged this problem of foreign companies flooding into U.S. markets to you when I co-wrote a cover story back when I was at Forbes Magazine in 2006.

And now, more than a quarter of the 94 U.S. securities fraud lawsuits filed in the first half seeking class-action status were targeted at so-called Chinese reverse mergers, according to a study released on Tuesday by the Stanford Law School Securities Class Action Clearinghouse and Cornerstone Research in Boston. Hungry for revenue from new listings, the exchanges are often to blame for putting investors at risk.

For instance, the American Stock Exchange, which has since merged with the New York Stock Exchange, took all comers during the most recent bubble. That included reverse mergers and "special purpose acquisition companies, which are also shells with zero operating history, zero revenue, no profits, and no staff. Just a hope and a prayer to buy a U.S. company to pour into the shell. 

The Big Board and Nasdaq at that time shunned them, but the Amex took them on to boost listing revenues, letting SPACs acquire something, anything, as long as a year and a half away, among other watery rules. So much for Sarbanes-Oxley.

The evil twin to SPACs are the companies that got a lease on life through a reverse merger. Chinese companies like Bodisen Biotech of Xi'an and Tiens Biotech Group USA of Tianjin.
Dont be fooled by their high falutin bio-tech sounding names. Bodisen actually manufactured fertilizer and pesticides, and was subsequently delisted. Tiens sold nutritional supplements. A company calling itself China Natural Gas was a pink sheet, Amex wannabe, but it wasnt a BP (BP) or an ExxonMobil (XOM): China Natural Gas ran nine gas stations in Xi'an.

Surprisingly, 16 of the 27 Chinese companies Disclosure examined were not reverse mergers, an area of recent market focus. And more than half, 56%, of the Chinese companies got its worst rating of being a High Risk investment. That compares with only 6% of non-Chinese companies rated "High Risk by Disclosure, out of a coverage library of 1,484 companies, Gavin said in a statement.

Which companies did Disclosure Insight list as high risk? Chinese solar companies, and China Eastern Airlines and China Life Insurance Co. to name a few.

Disclosure Insights Gavin also says the analysis shows a pattern of significant, chronic, and disproportional risk from companies listing here from China, spanning many industries, and included some of the larger and betterknown names. 

He added: Since we first started producing D.I. Reports in 2009, our risk profiling discipline has consistently compelled us to assign negative ratings to the vast majority of Chinese companies that we have reviewed. And he said: Upon updating our reports through this spring and summer, ratings for some of the companies have deteriorated as fraud allegations, auditor resignations, and other negative events have been reported."

Here are details behind some high-risk names -- the info is directly from Disclosure Insights report -- and the full list of the 24 companies Disclosure Insight flagged is at bottom:

Canadian Solar Inc. (CSIQ  $9.63 Mkt Cap  $419 Mil).
Check out this companys pretty website, showing a canoe on a mountain lake somewhere, and also its contact list showing it supposedly has offices in Canada, Japan, Germany and Italy, the  U.S., Korea and China. You may not get the impression this is a Chinese company. But Discclosure notes that this is from the Canadian Solar 20F filed 17May11 for the year ended 31Dec10:
" We are a Canadian company with substantially all of our manufacturing operations in China.
" Our principal executive office is located at 650 Riverbend Drive, Suite B, Kitchener, Ontario, Canada N2K 3S2.
" Our principal place of business is at No. 199 Lushan Road, Suzhou New District, Suzhou, Jiangsu 215129, Peoples Republic of China.

D.I. PROFILE: An ongoing SEC investigation; insider ownership; concentrated revenue; executive suite turnover; debt covenant violations; related party transactions; and the chairman and CEO positions being held by one person. In Jun10, CSIQ announced that it received a subpoena from the SEC requesting documents from the company relating to certain sales transactions in 2009. As of May11, the SEC investigation was ongoing. As of Mar11, Chairman, CEO & President Shawn (Xiaohua) Qu held 30% of the company's outstanding shares. One customer accounted for 11% of 2010 net revenue. There have been 3 CFOs since the companys IPO in Nov06. CSIQ had 2 debt covenant violations, which resulted in borrowings being due and payable and therefore classified as shortterm. The present status of the covenant violations and shortterm debt is not clear. In 2010, CSIQ outsourced module processing services to a joint venture (Suzhou Gaochuangte New Energy) established by the company, which purchased module products from the company and sold finished products back to the company after completion of the processing services. (Note: Related-party transactions like these are often a red flag). There were $2.1 million module products sold to Gaochuangte in 2010 for further processing and $2.1 million in finished goods purchased back from Gaochuangte. Chairman & CEO Dr. Qu fully guaranteed a oneyear RMB250 million loan facility from the Bank of Communications in 2010. Amount drawn down from the facility at Dec10 was $38 million. Founder Dr. Shawn (Xiaohua) Qu has served as both Chairman & CEO since Oct01.

D.I. PROFILE: Turnover in the CFO position; board departures; 3 auditors; internal controls issues; 16 amended filings; 5 delayed filings; and the chairman and CEO positions being held by one person support our opinion of a High Risk rating on CHNG.

CFO changes in Oct-08, Apr-09, Jan-10, and Dec-10 were each followed by the filing of an amended 10-K in Dec-08, Jul-09, Aug-10, and Jun-11, respectively. Of the 3 director departures, 2 were audit committee chairmen. The company has had 3 auditors. The current auditor, Friedman LLP, was appointed in Dec-10.

Additional deficiencies relating to the financial closing and reporting process and the treasury cycle were identified as of 31-Mar-09. Internal controls were reported effective as of 31-Dec-09. However, in the 2Q10 10-Q, the company disclosed that its internal controls were ineffective as of 31-Dec-09 due to a material weakness related to 3 transactions entered into by key executives without prior board approval.

Further, in the 1Q11 10-Q, the company reported that it had identified a material weakness relating to insufficient accounting personnel with U.S. GAAP expertise.
