  • Was first attorney on the ground as part of a fast moving internal inquiry on behalf of the company’s Audit Committee of the Board of Directors into certain accounting irregularities pertaining to an international facility. We were brought into the case late in the company’s SEC reporting cycle and worked rapidly with teams of lawyers and accountants in the U.S., Mexico and Europe to quantify an issue at a plant in Mexico, rule out similar issues at plants around the world, and assist the company with completing a restatement and self-report to the SEC. Our quick work allowed the company to avoid unnecessary harm to its investors due to the uncertainty associated with an open inquiry, which appeared to have helped the company avoid class action lawsuits that typically accompany these matters.
