Delaware Investments, which is owned by the Macquarie Group, is rebranding as Macquarie Investment Management to better reflect its global presence, the firm announced Monday.

Its U.S. registered mutual fund and separately managed account offerings will continue to carry the Delaware name. Macquarie Investment Management, headquartered in Philadelphia, has $256.9 billion in assets under management and employs more than 500 people in the Americas.

One of the oldest asset management firms in the United States, Delaware Investments was founded in 1929 at the start of the Great Depression and introduced its first mutual fund in 1938. Macquarie Group Limited acquired the firm from Lincoln Financial Group in 2010.

Macquarie Investment Management offers a suite of investments across equities, fixed income and listed alternatives.
