Janus Capital Corporation has purchased money market fund insurance for Janus
Money Market Fund and Janus Tax-Exempt Money Market Fund. This insurance will
protect the Funds in the event of, among other things, a decrease in the value
of a portfolio security due to the default or bankruptcy of the issuer. The
money market insurance policy covers all securities in which the Funds invest,
other than certain securities issued, guaranteed, or backed by the U.S.
government. Although the Funds seek to preserve the value of your investment at
$1.00 per share, the policy does not guarantee that a Fund will maintain a value
of $1.00 per share. The policy became effective on September 11, 2000 and will
expire on September 11, 2001 unless renewed.
