Vanguard, an investment management company, has appointed Joseph Brennan to the newly created position of global chief risk officer. He also will serve as a member of Vanguard’s senior leadership team.

In his new role, Brennan will assume responsibility for the firm’s current enterprise risk management organization, in addition to all facets of enterprise security and investment risk management. “We believe centralizing our risk management functions under a single senior leader will benefit both our clients and Vanguard,” Vanguard CEO Tim Buckley said in a statement. “Joe’s vast and varied investment management and leadership experience both in the U.S. and abroad make him the ideal candidate to integrate and enhance our capable and strong global risk management teams.”

Brennan joined Vanguard in 1991 and worked as an analyst and trader in Vanguard’s Fixed Income Group. He then moved to Vanguard’s Portfolio Review Department, which is primarily responsible for investment manager search and oversight, eventually leading the group for five years. In 2009, he was named chief investment officer of the Asia Pacific region and served on the senior leadership team of Vanguard Australia. In 2013, he assumed responsibility for Vanguard’s Equity Index Group.

Brennan’s current role as head of Vanguard’s Equity Index Group, which oversees $3.1 trillion in 319 mutual funds and ETFs, will be assumed by C. Rodney Comegys, principal and head of the Risk Management Group within Vanguard Investment Management Group, responsible for risk analysis oversight for the Fixed Income, Equity Index, and Quantitative Equity groups.
