The case is pending in the U.S. District Court for the Southern District of New York.NO CLASS HAS YET BEEN CERTIFIED IN THE ABOVE ACTION. UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY AN ATTORNEY UNLESS YOU RETAIN ONE. YOU MAY CHOOSE TO DO NOTHING AT THIS POINT AND REMAIN AN ABSENT CLASS MEMBER.The Complaint alleges that the Company made a number of misrepresentations in its public filings with the Securities Exchange Commission and in its press releases. Namely, that: (1) the Company misrepresented certain of its distribution arrangements; (2) that Advanced Battery paid $1.5 million to acquire another company that appears to be fake because its location and existence could not be verified; (3) that Advanced Battery paid $20 million to purchase a company, but failed to disclose the related party nature of the transaction; and (4) the Company misrepresented that it owned a Company subsidiary when it did not, or the Company failed to disclose that the Company entered into a related party transaction with the Company's Chairman and CEO which resulted in the owner of that subsidiary being the Chairman and CEO, and not Advanced Battery.On March 30, 2011 an analyst firm called Variant View Research issued a detailed report revealing the adverse information to the market. When these details of the Company's financial condition came to light on March 30, 2011, the price of Advanced Battery's stock fell over 40%, damaging investors.If you wish to serve as lead plaintiff, you must move the Court no later than May 31, 2011.
