For a Brazilian company involved in a dispute with a minority shareholder regarding certain accounting measures that were used in a covenant clause, Brattle provided testimony on the distinction between impairment of productive assets under GAAP and IFRS. Specifically, we determined that the assets correctly had been impaired under IFRS, but would not have been impaired under GAAP. The analysis required us to reverse the write-up of assets relied upon under IFRS. The International Chamber of Commerce (ICC) tribunal found in favor of our client.
