SPECIAL NOTICE: Courts will generally appoint only one law firm to prosecute a securities class action on behalf of the shareholders based upon the amount of losses its "lead plaintiffs" have suffered. Accordingly, while KGS urges you to sign up with the firm, KGS also encourages you to carefully evaluate any other firm you may consider to represent your interests in the SiRF class action, should you be considering another firm. Critical components of a law firm's ability to successfully prosecute this action and obtain a strong recovery for you include the resources it will dedicate to prosecution of the case, including the number of lawyers the firm has available for the SiRF action in particular, AND especially the quality of the firm's work. Interested shareholders are encouraged to call for consultation and to request more information about KGS.
