Company Release - 1/10/2005 4:45 PM ET

DENVER--(BUSINESS WIRE)--Jan. 10, 2005--For the month ended December 31, 2004, Janus Capital Group Inc. (NYSE:JNS) reported total assets under management of approximately $139.0 billion, which is up 1.2% from the prior month's assets of $137.4 billion. Firmwide average assets under management during December were approximately $137.5 billion compared with November's average assets of $136.3 billion, an increase of 0.9%. Excluding money markets, average assets in December were $126.3 billion.

Long-term (non-money market) net outflows were $1.6 billion in December. The outflow figure includes $1.8 billion of redemptions from ING that were announced in July 2004. Janus expects the remaining $2.7 billion of ING assets to be redeemed in March 2005.

For the third consecutive month, gross sales of Janus' long-term products (excluding INTECH and money markets) improved, outpacing November's gross sales by more than 35%. The company's INTECH subsidiary, which uses a mathematical, risk-managed investment strategy, continued to show strength in December, recording net inflows of approximately $1.6 billion.

Janus' relative mutual fund performance remained strong in December. As of December 31, more than 60% of the funds in the company's primary fund family, Janus Investment Fund (JIF), were in the top half of their Lipper categories on a 1-year, total-return basis. In addition, more than 68% of the JIF funds were in the top half of their Lipper categories on a 3-year, total-return basis at the end of December.
