Vanguard will invest $1 billion in hedge fund assets, a source said on Thursday, marking the first time the firm has ever invested in a hedge fund.

The investment will be made in the funds “vanguard” index fund, Vanguard said in a statement.

Vanguard plans to invest about $1.4 billion, with a maximum return of 5 percent.

The funds’ managers will earn a management fee of 0.1 percent, and the investment will pay out at a fixed annual rate.

The fund’s portfolio will include stocks, bonds and mutual funds.

The fund will also have access to Vanguard’s ETF, which offers investors more diversified investment options, according to the firm.

The firm has been a supporter of hedge funds since at least 2007.

It’s the latest investment by Vanguard.

In 2016, the firm invested $1 million in the U.K. Independence Fund, an American-focused fund.

The U.S. fund, meanwhile, has invested about $700 million in hedge-fund companies.
