Foster oversaw an investigation in the summer of 2007 of multiple branches in the Boston area of the subprime division. Investigators found evidence that employees had forged borrower signatures, altered and fabricated income and asset documentation, and manipulated the company's automated underwriting and property valuation systems. The investigation was opened after receiving a tip from a former branch employee who had been fired after objecting to the fraudulent practices. After her investigation, a number of employees were let go and Countrywide shut down six branch offices in Boston. By February 2008, Foster had found similar activities in investigations in Miami, Chicago, Cincinnati, San Diego, Las Vegas and Los Angeles. Foster believed that Countrywide Employee Relations and Lending Managers were colluding to circumvent fraud reporting channels in order to conceal the fraud perpetrated by high-producing loan officers and managers. According to a 60 Minutes interview,
whistleblowing employees were told to circumvent Foster's office and were instead directed to report fraud and wrongdoing to the company's Employee Relations department. Those employees were allegedly being transferred, demoted, harassed or terminated. Foster asked Countrywide's Internal Audit to investigate Employee Relations. The company chose to conceal Foster's allegations from Bank of America (with whom they were merging) and instead directed Employee Relations to investigate Foster. Foster's allegations of retaliation were ignored and Countrywide's Employee Relations convinced Bank of America managers to terminate Foster on September 8, 2008. Foster was offered $228,000 for her silence. She instead filed a Sarbanes-Oxley Act whistleblower complaint with the Occupational Safety & Health Administration (OSHA), challenging the legality of her firing. In September 2011, OSHA ruled that Foster had been retaliated against in violation of the employee protection provision of the Sarbanes Oxley Corporate and Criminal Fraud Accountability Act of 2002. The Department of Labor ordered her reinstatement and $930,000 in damages. Bank of America has challenged OSHA's ruling. Another hearing has been set for October 2012. ==Ridenhour Prize for Truth-Telling==
