Effective July 1, 2013, the minimum subsequent investment amount for purchases made through an automatic investment program is $50.00. The following sections of each Fund’s Prospectus are updated as noted:

1.  In the “Purchase and Sale of Fund Shares” section found in the Fund Summary for each Fund and in the “Doing Business with Janus” section found in the Shareholder’s Manual of each Fund’s Prospectus, the following table replaces in its entirety the corresponding table:

• without an automatic investment program	$	1,000

To add to any existing type of Fund account without an automatic investment program	$	100
To add to any existing type of Fund account with an automatic investment program	$	50

2.  In the “To Open an Account or Buy Shares” section found in the Shareholder’s Manual of each Fund’s Prospectus, the following replaces in its entirety the corresponding information:

   By Automated Investments

   •  To buy additional shares through the Automatic Investment Program, you select the frequency with which your money ($50 minimum) will be electronically transferred from your bank account to your Fund account. Certain tax-deferred accounts are not eligible for automated investments.

   •  You may buy additional shares using Payroll Deduction if your employer can initiate this type of transaction. You may have all or a portion of your paycheck ($50 minimum) invested directly into your Fund account.

3.  In the “Paying for Shares” section found in the Shareholder’s Manual of each Fund’s Prospectus, the fourth bullet is replaced in its entirety by the following bullet:

   •  When purchasing Shares through the Automatic Investment Program, if no date or dollar amount is specified on your application, investments of $50 will be made on the 20th of each month. Your first automatic investment may take up to two weeks to establish. If the balance in the Janus fund account you are buying into falls to zero as the result of a redemption or exchange, your Automatic Investment Program will be discontinued.
