In a jury trial in federal court, we testified on behalf of Amerada Hess as to the appropriate damage theory and amount of damages for the breach of a natural gas supply contract between a gas producer and marketer (Hess). The jury returned a verdict that adopted our damage estimate. On appeal, the federal appeals court affirmed the jury verdict and cited our damage theory for its consistency with legal principles associated with the “anticipatory repudiation” of long-term contracts.
