Gary Black was named CEO of Aegon Asset Management US, said a news release from the company Wednesday.
Sarah Russell, CEO of parent company Aegon Asset Management, based in The Hague, Netherlands, had been serving as interim CEO of the U.S. operations. The company's U.S. firm has seen departures of several top executives over the past several years.
Ms. Russell took over in the interim in February 2015 for Thomas Swank, who left the CEO position after only eight months. Other key executives who have left include Brad Beman, global chief investment officer; and William Frank Koster, head of U.S. fixed income.
Mr. Black will be reporting to Ms. Russell and will start June 27.
Mr. Black was global co-CIO at Calamos Investments until last year. He was not directly replaced. In March of this year, John Koudounis was named CEO of Calamos Investments, replacing firm founder John P. Calamos Sr., who retained his chairman and global CIO titles. Mr. Black had shared the global CIO position with Mr. Calamos.
Mr. Black also served as president and CIO at Janus Capital Group from April 2004 to January 2006 and then CEO until July 2009.
Mr. Black will be in charge of Aegon's U.S. operations and will be based in Chicago. Aegon's main U.S. operations are in Cedar Rapids, Iowa.
Armel Leslie, a spokesman for the firm, said company officials would not be available for an interview.
