The exodus from the U.S. Securities and Exchange Commission (SEC) continues with the news that the regulator’s head of enforcement, Andrew Ceresney, plans to leave the agency by the end of the year.

This latest departure follows the announcement that SEC chairwoman Mary Jo White is leaving, as are several other senior executives at the regulator, including its chief accountant, chief economist, the head of corporate finance, chief litigation counsel and the head of its corporate finance division, among others.

The SEC reports that, during Ceresney’s four-year tenure, the regulator filed more than 2,850 enforcement actions and obtained judgments and orders for more than US$13.8 billion in monetary sanctions.

“Under Andrew’s strong leadership, the enforcement division took its already robust enforcement program to an even higher level, achieving unprecedented results, including a record number of enforcement actions, first-of-their-kind cases and a first ever admissions policy for a civil law enforcement agency,” says White in a statement.
