Money market mutual fund shares are 'obligations' issued by money market mutual funds, which are open-end investment companies that invest in short-term, liquid assets, including short-term municipal securities.
The funds began operating in the 1970s and quickly became popular with investors as a higher-earning alternative to deposits.
The shares may be redeemed at any time, although funds usually require that a minimum balance be retained in each account.
