White Collar Investigations & Litigation

Brattle economic experts assist legal teams in financial services investigations that pose the risk of criminal prosecution.

Well before considering the need for experts to analyze financial market conduct, fraud claims, and damages, Brattle economists assist legal teams in investigations that are document, financial, and accounting data-intensive to develop the facts and assess the weight of evidence of potential misconduct.

We provide clear, detailed analyses to executives, corporate boards, special committees, investigators, and litigators that retain us to help answer key questions posed in investigations. Brattle provides consulting expertise from start to finish in investigations, as well as economic expert testimony in enforcement proceedings and litigation if cases proceed beyond the investigation stage.

Brattle experts provide testimony and economic analysis on a wide range of issues including:

  • Analysis of trading and hedging activity
  • Forensic analysis
  • Big data analysis and document analytics
  • Fiduciary duties, custom and practice
  • Regulatory compliance with conduct and disclosure rules
  • Economic damages and causation

Areas of Expertise


Below is a list of representative engagements for our White Collar Investigations & Litigation practice.

U.S. v. Naseem insider trading
A Brattle principal worked with the testifying expert in a high-profile case involving a former Credit Suisse banker accused of insider trading and conspiracy to commit securities fraud. The testimony dealt with complex issues regarding the (lack of) materiality, and the importance of accurately accounting for the information mix available to investors in capital markets from all potential sources at a particular point in time. We analyzed case-specific facts, the information mix in the market, the timing and relevance of detailed accounting information and stock price data to explain how the nature and quality of publicly-available information influenced both investment decisions and the traded value of the securities.
Money laundering
The Brattle Group was retained by the Criminal Division of the U.S. Department of Justice to support an investigation revolving around a $6 billion digital currency money laundering scheme. Brattle’s team assisted the DOJ in identifying evidence indicative of money laundering activities within the massive haystack of structured and unstructured data at hand. By assembling, standardizing and integrating data from different sources and leveraging sophisticated data analytics, Brattle’s team was able to uncover anomalies and patterns that were indicative of illicit activity. The investigation is believed to be the largest international money laundering prosecution in history.
False Claims Act: U.S. v. Countrywide / BofA
In landmark litigation against a major U.S. financial institution under the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA), Brattle experts helped to identify and recruit multiple experts and advise counsel on case-specific facts and considerations from inception through trial. We coordinated rigorous review of millions of documents produced and used in discovery, as well as analysis of loan-level data to determine the information known about the quality of the loans in question, management’s actions, the causes of loan defaults, and the extent of resulting damages. We assisted counsel in real-time before and during trial, which ended in a jury verdict favorable for the client on liability and a $1.3 billion damages award.
