buck was First Multifund for Daily Income (FMDI) in 1978, liquidating and restating NAV at 94 cents per share. An argument has been made that FMDI was not technically a money market fund as at the time of liquidation the average maturity of securities in its portfolio exceeded two years. However, prospective investors were informed that FMDI would invest "solely in Short-Term (30-90 days) MONEY MARKET obligations". Furthermore, the rule restricting which the maturities which money market funds are permitted to invest in, Rule 2a-7 of the Investment Company Act of 1940, was not promulgated until 1983. Prior to the adoption of this rule, a mutual fund had to do little other than present itself as a money market fund, which FMDI did. Seeking higher yield, FMDI had purchased increasingly longer maturity securities, and rising interest rates negatively impacted the value of its portfolio. In order to meet increasing redemptions, the fund was forced to sell a certificate of deposit at a 3% loss, triggering a restatement of its NAV and the first instance of a money market fund "breaking the buck". The Community Bankers US Government Fund broke the buck in 1994, paying investors 96 cents per share. This was only the second failure in the then 23-year history of money funds and there were no further failures for 14 years. The fund had invested a large percentage of its assets into adjustable rate securities. As interest rates increased, these floating rate securities lost value. This fund was an institutional money fund, not a retail money fund, thus individuals were not directly affected. No further failures occurred until September 2008, a month that saw tumultuous events for money funds. However, as noted above, other failures were only averted by infusions of capital from the fund sponsors. September 2008 Money market funds increasingly became important to the wholesale money market leading up to the crisis. Their purchases of asset-backed securities and large-scale funding of foreign banks' short-term US-denominated debt put the funds in a pivotal position in the marketplace. The week of September 15, 2008, to September 19, 2008, was very turbulent for money funds and a key part of financial markets seizing up. Events On Monday, September 15, 2008, Lehman Brothers Holdings Inc. filed for bankruptcy. On Tuesday, September 16, 2008, The Reserve Primary Fund broke the buck when its shares fell to 97 cents after writing off debt
