She also played a key role in two of the largest securities fraud recoveries in U.S. history, both of which settled near trial for billions of dollars on behalf of investors:
- In re Bank of America Securities Litigation: Katie was an integral member of the trial team that prosecuted the securities fraud action against Bank of America related to the company’s acquisition of Merrill Lynch & Co., achieving a recovery of $2.425 billion—one of the top seven U.S. securities class action recoveries of all time.
