I didn't realize whistleblowers could recover part of fraud settlements:

> The civil settlement includes the resolution of claims brought under the qui tam or whistleblower provisions of the False Claims Act by Sholto David. Under those provisions, a private party can file an action on behalf of the United States and receive a portion of any recovery. David will receive $2,625,000 under today’s settlement.
