    • Our lawyers are among a select few who have successfully tried securities-related cases to jury verdict. 
    • We were the first firm to form a task force dedicated solely to counseling China-based companies that have US exchange-listed shares on the increased scrutiny by the US Securities and Exchange Commission, Congress, and the plaintiffs’ class-action bar.
