One of the world's more famous money managers has parted ways with a hedge fund that oversees US$6.84 trillion in assets.

Mark Wiseman was the global head of active equities at BlackRock Inc., which has a market capitalization of US$75.5 billion.

Today, the company announced that Wiseman has left after violating the company's policy regarding work relationships.

BNN Bloomberg has reported that Wiseman did not disclose a consensual relationship with a colleague.

According to Investopedia, BlackRock is the sixth-largest hedge fund in the world with about 11,000 employees.

Wiseman was president and CEO of the Canada Pension Plan Investment Board before joining BlackRock in 2016.

He had been chairing BlackRock Alternative Investors and the company's global investment committee.

Wiseman was born in Niagara Falls and once served as a law clerk to former Supreme Court of Canada chief justice Beverley McLachlin.
