In an insurance dispute between Brattle’s client, a broker-dealer, and a large bank whose natural gas trader was alleged to have caused hundreds of millions in trading losses, the bank alleged that an employee of Brattle’s client colluded with the bank’s trader by providing incorrect pricing inputs to the bank’s internal auditors. Brattle traced and analyzed the bank’s internal trading records, replicated internal valuation, and performed a forensic accounting analysis of the bank’s journal entries and financial restatements to determine the portion of losses possibly related to potential pricing irregularities, as opposed to losses caused by unrelated causes. The case was settled on favorable terms for our client.
