Vanguard closed the $9.1 billion fund in January 2009 to protect existing clients from high levels of cash flow that could potentially dilute the fund's yield. Market conditions have since improved, and the fund's Board determined that it would be in the best interests of shareholders to reopen the fund.

Vanguard investors will now have access to two low-cost U.S. government money market funds. The firm announced in June that it was reopening its $4.8 billion Federal Money Market Fund (VMFXX) to all investors. The Treasury Money Market Fund invests primarily in U.S. Treasuries, while the Federal Money Market Fund invests primarily in U.S. agency debt.

As U.S. government money market funds, both funds provide investors with a stable $1 net asset value (NAV). Moreover, they will not be subject to new liquidity fee or redemption gate requirements under rules adopted by the Securities and Exchange Commission (SEC) in 2014.

Vanguard's Treasury Money Market Fund and Federal Money Market Fund currently invest more than 99.5% of their total assets (the percentage at which the rules define a U.S. government money market fund) in cash, government securities, or repurchase agreements that are collateralized solely by government securities or cash. They will continue to adhere to this standard.
