Philidor has been accused of charging customers for higher-priced drugs rather than cheaper generics among other questionable practices. Valeant management already appeared in front of a congressional hearing together with the so-called "pharma-dude" Martin Shkreli. The controversy around Philidor also triggered allegations of accounting fraud. In January, the company announced it may restate past financial results due to improper revenue recognition practices with Philidor. Valeant shares are down 70% from their 2015 peak. Although Pearson has been on a medical leave of absence since December, it is time for the Valeant board to fire the long-time CEO.
