The U.S. Securities and Exchange Commission on Friday announced a whistleblower award of more than US$2.1 million to a former company insider whose information led to multiple successful enforcement actions.

The whistleblower’s information “strongly supported” the SEC underlying enforcement actions, and also provided ongoing assistance during its investigation, the regulator says.

To protect the anonymity of whistleblowers, the SEC does not disclose the details of these cases.

With this latest award, the SEC has now paid more than US$266 million to 55 individuals under the whistleblower program, which began in 2012.

These cases have generated almost US$1.5 billion in monetary sanctions against wrongdoers, including more than US$740 million in disgorgement of ill-gotten gains.

“The SEC has issued nearly US$90 million in whistleblower awards in the past month alone,” says Jane Norberg, chief of the SEC’s Office of the Whistleblower, in a statement. “As these awards demonstrate, we continue to receive high-quality information from whistleblowers, which we use to detect and prosecute securities violations and safeguard investors.”
