A source told Reuters in September that at least one member of Guggenheim's board of directors pressed Guggenheim CEO Mark Walter, an owner and the chairman of the Los Angeles Dodgers baseball team, to resign after he became the subject of news coverage. A spokesman rebutted that source, saying Walter was not being pushed out of the investment firm he helped found.

That report followed a Financial Times story in July that said there was a "power struggle" between Minerd and Walter. Both men denied that report.

When asked on Tuesday about Walter's future, Minerd said: "I think Mark will be involved with the firm. Will he be CEO? Probably not forever. Mark has other business interests."

News stories have questioned Walter's relationship with an employee, Alexandra Court, and her elevation to a role overseeing institutional distribution.

Court is in the process of negotiating a possible exit from the company, according to a person familiar with the matter. She did not respond to a request for comment.

Walter is not listed among executives, including Executive Chairman Alan Schwartz, Minerd and others attending the firm's 2018 investment outlook summit at New York's Solomon R. Guggenheim Museum. The event, originally planned for Monday, was rescheduled to March.

Guggenheim also faces scrutiny from the U.S. Securities and Exchange Commission about an investment it made in a London-listed company focused on banking operations in Africa, named Atlas Mara Ltd, according to a person familiar with the matter.

Guggenheim previously declined to comment on that examination, but denied wrongdoing on that transaction and others that raised concerns in a letter to one client seen by Reuters. Atlas Mara, which was not accused of wrongdoing, did not comment.

"Although Guggenheim has dismissed many of the speculations from our conversations we think the situation at the firm is not great and the work environment there has indeed deteriorated in the recent months," investment consultant NEPC LLC said in a September commentary published online by one of its clients. NEPC declined to comment.

"I am a harsh judge, especially of myself, and I always say, we could've done so much better," said Minerd. "But we really did try to stay in contact with our institutional clients and our retail distributors, so that they were kept as current as they could be."
