Total Return Bond Portfolio Management Team

American Century Investments, a $245 billion* global investment manager, has hired the portfolio management team responsible for Aberdeen Standard Investments’ Total Return Bond strategy. Vice President and Senior Portfolio Manager Lynn Chen, CFA; Portfolio Manager and Senior Sovereign Analyst Rajat Ahuja; Portfolio Manager and Senior Corporate Analyst Svetlin Krastev, CFA, and Portfolio Manager and Senior Securitized Analyst Michael Waggaman joined American Century earlier this month. The team will manage American Century’s Total Return Bond strategy, utilizing the same methodology they employed at Aberdeen, and they will also assume additional portfolio management responsibilities.

“This investment team has significant experience and has worked together for more than 14 years,” said American Century Global Fixed Income Co-Chief Investment Officer Charles Tan. “Hiring Lynn, Raj, Svetlin and Michael not only allows us to add a strategy that has generated alpha for its clients but also deepens our expertise in developed markets and emerging markets across a variety of sectors and helps us better serve our clients.” Tan previously managed this team at Aberdeen, where he was head of North American Fixed Income before joining American Century in 2018.

The Total Return Bond strategy is an intermediate duration, fixed income strategy that uses a sector and country rotation strategy to invest in a diversified portfolio of investment grade, U.S. dollar (USD) debt securities with the ability to invest up to 40 percent of the portfolio in non-USD government debt securities in developed and emerging economies. “We use a top-down, macroeconomic-driven approach complemented by bottom-up inputs to invest the strategy,” said Senior Portfolio Manager Lynn Chen. “The strategy seeks to provide diversified alpha by capitalizing on opportunities around the world in any investment climate. We’re honored to be joining American Century, a company that has distinguished itself through its investment management expertise and an operating model that results in a positive impact on society.”

Chen noted that American Century’s unique ownership structure was one of the things that attracted her team to the firm. “The firm provides a solid platform for the TRB team to leverage resources, and its long-term focus aligns with client needs and should make the strategy more impactful.” Each year, more than 40 percent of American Century’s dividends are distributed to the Stowers Institute for Medical Research, a world-class biomedical research organization dedicated to defeating life-threatening diseases.

The Aberdeen team joins American Century’s Global Fixed Income discipline, which is comprised of 48 investment professionals averaging 21 years in the industry and is overseen by the firm’s Global Fixed Income co-Chief Investment Officers Charles Tan and John Lovito. The discipline represents $46 billion in assets under management as of June 30, 2021.
