Thank you for your contacting us about Longwei Petroleum Investment Holding.
If the court certifies a class of shareholders and you purchased your shares during the Class Period defined by the court, you would automatically be included as a member of the class. If you do not serve as Lead Plaintiff, there is no action that you need to take at this time. If and when the case settles, you should be notified by a claims administrator. We recommend that you retain your trading records as you would need these to provide proof of your transaction history to file a Proof of Claim.
The prosecution of a class action is often lengthy. Please visit our website www.pomerantzlaw.com for updates on the case.
