Our Focus:

Below is a list of representative engagements for our Regulatory Investigations & Enforcement practice.

Valuation of illiquid securities

Brattle experts consulted to and testified on behalf of the DOJ in the criminal case, US v. Ahuja, et al. In this matter, hedge fund managers were accused of overstating the value of illiquid structured finance securities. We summarized and analyzed contemporaneous data, including data relative to various pricing benchmarks, to establish that the hedge fund managers selectively relied on a subset of available information about the value of the securities in question to over-value them. Brattle testified at trial to present this analysis to the court and the jury. The hedge fund managers were found guilty, and the court cited Brattle’s analysis and testimony as a key component in this determination and sentencing.

Trading of foreign exchange (FX) derivatives

In US v. Bogucki, Brattle was engaged as the expert team on behalf of Barclays FX options trader Robert Bogucki in his criminal defense of charges of wire fraud for allegedly trading against a large FX options order from Hewlett Packard (HP). DOJ prosecutors alleged that Mr. Bogucki, with the benefit of confidential information, lied to HP and engaged in illegal front-running to push down the value of HP’s options. Brattle analyzed the trades at issue, studied communications between traders and HP, reviewed risk and governance practices concerning firm and regulatory expectations, and examined other aspects of the FX market –including trading volumes and the behavior of other market makers. Mr. Bogucki was acquitted by way of a Rule 29 motion after one week of testimony in front of a jury.

Manipulation of internal controls

The SEC retained Brattle in a matter in which the SEC accused a company’s financial executives of manipulating internal controls to allow improper premature revenue recognition. Brattle supported an accounting and internal controls expert who examined the various controls that the defendants claimed to be effective. The expert opined that the company actually had a material weakness in its internal controls that the defendants failed to disclose to the company’s auditors and in its financial statements. The SEC settled this matter with the defendants.

Confidential investigation of alleged manipulation

Brattle provided economic analyses, reports, and live interaction with the FERC’s Office of Enforcement to assist with the defense of a large energy trading company suspected of using physical power trades to game market rules and manipulate the value of related physical and financial derivatives positions. The analyses demonstrated that the trades at issue were executed in pursuit of stand-alone profits (and thus without fraudulent intent), and that the related positions were not aligned to benefit from the behavior. The investigation was dropped by the regulator.
