After this week's $22 million award to a whistleblower, SEC leaders called the whistleblower program a game changer that has transformed the SEC's ability to protect investors.
More than $107 million has been awarded to 33 whistleblowers.
The biggest award was more than $30 million in 2014. This week's $22 million award was the second biggest.
Whistleblower tips have helped the SEC bring successful enforcement actions "where more than $504 million was ordered in sanctions, including more than $346 million in disgorgement and interest for harmed investors," the agency said.
