JANUS ANNOUNCES FEBRUARY ASSETS UNDER MANAGEMENT

Executives to Speak at Investor Conference

DENVER- For the month ending February 29, 2004, Janus Capital Group Inc. (NYSE: JNS) reported total assets under management of approximately $147.5 billion, which is down 0.9% from the prior month’s assets of $148.8 billion. Firmwide average assets under management during February were approximately $148.6 billion compared with January’s average assets of $151.8 billion, a 2.1% decrease.

The combination of market appreciation and decreased net outflows resulted in only a slight decline in long-term (non-money market) assets over the prior month. Long-term assets were approximately $134.0 billion at the end of February versus $134.6 billion at the end of January, a decrease of 0.4%. Long-term average assets in February were $135.4 billion, which is down 0.7% from January’s long-term average assets of $136.4 billion. Excluding money market funds, net outflows for the month of February were $2.0 billion compared to net outflows of $3.1 billion in the month of January.

As discussed in our fourth quarter earnings call, year-end is a period of client re-evaluation for Janus’ Institutional Clients. Janus’ Institutional Clients, excluding INTECH, represented $74.9 billion of long-term assets under management at December 31, 2003 and represent the insurance, defined contribution, separately managed and subadvised channels. These channels are included in the Third-party Administrator/Adviser-assisted and Private / Subadvised distribution segments. During the past three months, Janus’ reported outflows have reflected $1.8 billion of gross redemptions related to re-evaluations by Janus’ Institutional Clients ($0.6 billion in December, $0.7 billion in January, and $0.5 billion in February). However, there is often a lag for institutional clients between notification of an intent to withdraw assets and the actual outflow.

Based on notifications received through the end of February, we estimate that over the next three months Janus’ Institutional Clients will withdraw an additional $4.5 billion of assets ($0.7 billion in March, $1.3 billion in April, and $2.5 billion in May). Approximately 80% of these redemptions are expected in the subadvised channel, and over 40% of withdrawals in this channel are from a single client who has decided to move a significant portion of the management of their assets in-house. While some clients continue the year-end re-evaluation process, we believe that these prospective outflows represent the substantial impact from the year-end review process.

As a result of the notification to withdraw the aforementioned assets by certain sub-advised accounts, Janus expects to record a write-down of intangible assets totaling approximately $14 million in the first quarter of 2004. After this impairment, the remaining value allocated to subadvised accounts will be approximately $28 million. To the extent that additional subadvised accounts notify us of withdrawals, Janus will recognize additional impairments equal to the unamortized value of the lost accounts.

Partially offsetting these prospective outflows, the INTECH products continue to show strength, and we have received notification of INTECH inflows (mandated but not yet funded) of approximately $1.7 billion during the next three months.

Consistent with our effort to increase transparency into the year-end re-evaluation process, we have attached an exhibit that breaks out assets and flows by investment discipline for December, January and February.
