My recommendation. Ask employees the following question. Are you aware of outright fraud? i.e. Are we complacent in fraud by not disclosing fraudulent testing to the FDA?
It is the boards duty after aquiring a company and then undercovering fraud to report it to the SEC. Since the employees of the company acquired were complacent in the fraud and are now part of Phillips the board should disclose it.
Dear board of directors: I doubt that you are aware of fraud. You acquired a company that did not disclose fraud to the SEC when they should have. However you could easily conduct a survey asking employees to come forward if they are aware of test results that supported a FDA decision that were fraudulent. You have numerous employees on staff that should say yes.
