While tredleon was being an a$$ with his reply, he is correct, the CFO didn't quit, but was fired. From 2011 annual report. Company politics at the top can be brutal.
ITEM 3. LEGAL PROCEEDINGS In December 2008, our former chief financial officer, Richard J. Klein, used our Whistleblower Policy procedures to report to the chairman of our audit committee that we had submitted grant reimbursement claims to the NIH for work that we had not performed. In accordance with the Whistleblower Policy and its charter, our audit committee, assisted by special outside counsel, commenced an independent investigation of our NIH grant and claims procedures. The investigation concluded that we had not submitted claims to the NIH for work we had not performed. In January 2009, we terminated Mr. Klein’s employment for reasons other than this incident. We subsequently voluntarily reported to the NIH Mr. Klein’s whistleblower report and the audit committee findings; in June 2009 the NIH confirmed to us in writing that it was satisfied with our handling of the grant matters that were the subject of Mr. Klein’s whistleblower report.
