The Securities and Exchange Commission has once again shown it will not hesitate to reward compliance officers who report securities law violations—provided they follow the rules.

The Commission awarded a compliance executive $450,000 last month for blowing the whistle, bringing the total amount of whistleblower awards to compliance personnel to more than $2.1 million. The first award given to a compliance employee was in 2014 for $300,000, which was followed by an award of more than $1.4 million given to a compliance professional in 2015.
