During this time she was the number one profit maker in the country. Bell took over the Medicare billing because of her great track record and success with cost efficiency. Bell later determined, however, that a significant percentage of patient files were not in compliance because they lacked the correct documentation. Bell also discovered that there was improper testing of oxygen patients. Bell instructed her billing department to "shut down the billing." Compliance officers came to Texarkana. When they arrived, Bell told them the results of her audit. They informed Bell that they knew that they were significantly out of compliance. Bell told them that she "was not going to Medicare prison for ROTECH," and refused to restart the billing. Bell was told that ROTECH was in the middle of a settlement agreement with the Government and could not do anything that might put up a "red flag." ROTECH paid $2 million to settle civil charges that it engaged in false or fraudulent conduct in billing Medicare for durable medical equipment. The government declined intervention. This settlement netted the client and government about $1.78 million. On July 2, 2012 the British pharmaceutical company GlaxoSmithKline agreed to pay the U.S. government $3 billion to settle civil and criminal charges in the largest healthcare fraud settlement in U.S. history and the largest payment ever by a pharmaceutical company. The settlement also resolved four lawsuits pending in federal court in the District of Massachusetts four separate qui tam cases brought by whistleblowers under the False Claims Act. The civil charges were settled for $2 billion of the total $3 billion resolution, a record number for civil settlements brought under the False Claims Act. GSK pleaded guilty to promoting drugs for uses not approved by the FDA, also known as "off-label" marketing, and to failing to report key safety data regarding a product. Others charges in the suit include false price reporting practices, Medicaid fraud, and paying illegal kickbacks to physicians. In April 2012, Alliant Techsystems Inc. agreed to a $36,967,160 settlement to resolve allegations that ATK sold dangerous and defective illumination flares to the Army and the Air Force. According to the government's allegations, from 2000 to 2006, ATK delivered LUU-2 and LUU-19 illuminating para-flares to the Defense Department. These flares, which burn in excess of 3,000 degrees Fahrenheit for over five minutes, are used for nighttime combat, covert and search and rescue
