Litigation funder Burford Capital is facing a shareholder class action lawsuit after it was accused of being insolvent and of doctoring its returns earlier this month.

The Rosen Law Firm is representing Burford securities investor Stephen Merz in the lawsuit filed in the U.S. District Court for the Eastern District of New York. Merz accuses the funder of misrepresenting or failing to disclose signs of adverse business conditions, citing Burford’s annual reports going back to 2014 and a report released by Muddy Waters on Aug. 7.
