It's important to note that the company who wrote this report makes money by shorting stocks and then putting out negative reports about them. This is not to say that the allegations are false, and, in fact, many such reports by similar companies have been true, and excellent works of investigative journalism. However, this type of report often turns out to be nothing more than market manipulation and fraud. So all of these allegations should be taken with a grain of salt.

edit: Since multiple people asked, source is I used to trade a lot and have been in trades where entities like this have put out similar fraud reports that have turned out to be false, and also seen others that were true. Also it's common sense that you should always question statements from people who stand to benefit from them.
