Expert.

Wallace alleged that he had been retaliated against in violation of the Sarbanes-Oxley Act; the dispute about the objective reasonableness of his beliefs about the disclosure of sales tax payments in turn led to an accounting dispute, which Wallace lost after his expert was found to not have been properly disclosed. Wallace argued that the pertinent testimony was lay rather than expert, but the Fifth Circuit disagreed:

Rule [the expert]’s training, education, and experience included “‘refinery economics, strategy management for commercial crude oil, business development,’ and . . . ‘transfer pric[ing] between operating segments.’” Notably, Rule did not deal explicitly with tax calculations, SEC reporting requirements, or investor relations. We conclude that Rule’s declaration as to paragraph 22 could not have been based on his lay experience as a Tesoro employee but rather on specialized accounting knowledge. Rule’s opinion on the application of tax accounting definitions to the SEC disclosures is an example of Rule applying his “specialized knowledge” to “help the trier of fact . . . understand the evidence.
