OppenheimerFunds has named Mary Ann Picciotto as chief compliance officer. She assumes this position from Mark Vandehey, who is retiring after more than 31 years with the company.

As CCO, Picciotto will be responsible for all aspects of regulatory compliance for OppenheimerFunds' five affiliated investment advisers, as well as its three commodity pool operators and advisers, two transfer agents, broker-dealer, and state-chartered trust company.

She will oversee a staff of more than 30 compliance professionals in three U.S. locations, and will report directly to OppenheimerFunds General Counsel Ari Gabinet.

Picciotto joins the company from Morgan Stanley Investment Management, where she most recently served as global head of compliance and chief compliance officer for the Morgan Stanley funds. Previously, she worked for PwC on the assurance and business advisory services team in the investment management services division.
