John W. Zimmerman, managing director of Janus Capital Group’s institutional asset management division, will leave the company, effective Aug. 24.

In the meantime, Gary Black, CEO of Denver-based Janus Capital Group, will fill in for Mr. Zimmerman as the firm searches for a successor.
Mr. Zimmerman has been with Janus since 2004. Prior to becoming managing director, he was senior vice president of institutional asset management.
