The changes, which went into effect on November 1, 2017, reflect Vanguard Equity Index Group’s team-based, risk-controlled approach to managing investment portfolios, under which new managers are periodically added to funds and experienced managers are offered new responsibilities. This approach helps to strengthen the team’s overall investment capabilities across sectors and markets and helps to ensure a strong investment talent pipeline.

“For more than 40 years, Vanguard has been an industry leader in developing and managing index funds, employing seasoned professionals and using proprietary trading strategies to manage portfolios effectively and efficiently,” said Vanguard Chief Investment Officer Greg Davis. “With these changes, our clients across the globe can benefit from the nearly 100 years of combined investment management experience these portfolio managers bring to the funds.”

Importantly, these changes won’t affect the investment objectives, strategies, philosophies, or overall portfolio management process of any of the funds. No other changes are being made to any of the funds’ investment management teams at this time.

“These recently named portfolio managers are able to draw on their diverse perspectives and deep knowledge of Vanguard’s fund management approach to help ensure we deliver precise tracking to our benchmarks and competitive investment performance to our clients,” said Joe Brennan, global head of the Equity Index Group.
