JANUS INVESTMENT FUND
JANUS MONEY MARKET FUND
Institutional Shares
Supplement Dated June 10, 1998 to Prospectus Dated February 17, 1998
Effective June 10, 1998, the minimum investment for the Institutional Shares of
Janus Money Market Fund will be $5,000,000. Shares may be purchased with an
initial $250,000 investment, however, the $5,000,000 minimum must be reached
within six months of opening the account. Shareholders who do not reach or
maintain the $5,000,000 minimum will be given the option of (1) exchanging into
Investor Shares of Janus Money Market Fund, Institutional Shares of Janus
Government Money Market Fund or Janus Tax-Exempt Money Market Fund, or shares of
another Janus fund or (2) having their shares redeemed. Shareholders' balances
that fall below the required minimum will have 30 days to reach an account
balance of $5,000,000. The new investment minimum does not apply to shareholders
who opened accounts prior to June 10, 1998; the $250,000 minimum will continue
to apply to them.
The change described above replaces the "Minimum Investment" section of the
prospectus on page 18.
