Revenues of $37.2 billion, a 29% increase over 2003. Excluding the impact of acquisitions, revenues increased 8% over 2003.
Uniprise revenues in 2003 were $3.1 billion, representing an increase of 14% over 2002. This increase was driven primarily by growth of 6% in the number of individuals served by Uniprise during 2003, annual service fee rate increases for self-insured customers, and a change in customer funding mix during 2002. Uniprise served 9.1 million individuals and 8.6 million individuals as of December 31, 2003 and 2002, respectively.
In February 2004, we issued $250 million of 3.8% fixed-rate notes due February 2009 and $250 million of 4.8% fixed-rate notes due February 2014. We used the proceeds from the February 2004 borrowings to finance a majority of the cash portion of the MAMSI purchase price as described above.
We conduct a significant portion of our operations through companies that are subject to standards established by the National Association of Insurance Commissioners (NAIC). These standards, among other things, require these subsidiaries to maintain specified levels of statutory capital, as defined by each state, and restrict the timing and amount of dividends and other distributions that may be paid to their parent companies. Generally, the amount of dividend distributions that may be paid by a regulated subsidiary, without prior approval by state regulatory authorities, is limited based on the entity’s level of statutory net income and statutory capital and surplus. The agencies that assess our creditworthiness also consider capital adequacy levels when establishing our debt ratings. Consistent with our intent to maintain our senior debt ratings in the “A” range, we maintain an aggregate statutory capital level for our regulated subsidiaries that is significantly higher than the minimum level regulators require. As of December 31, 2004, our regulated subsidiaries had aggregate statutory capital of approximately $4.1 billion, which is significantly more than the aggregate minimum regulatory requirements.
As of December 31, 2004, we had no investments in a continuous unrealized loss position for 12 months or greater. Gross unrealized losses of $11 million were largely due to interest rate increases and relate to debt securities with an aggregate fair value of $1.8 billion at December 31, 2004.

At December 31, 2004, approximately $227 million of our $12.3 billion of cash and investments was held by non-regulated subsidiaries. Of this amount, approximately $37 million was segregated for future regulatory capital needs and the remainder was available for general corporate use, including acquisitions and share repurchases.
the American Medical Association, a third amended complaint was filed. On October 25, 2002, the court granted in part and denied in part our motion to dismiss the third amended complaint.

On May 26, 2004, we filed a motion for partial summary judgment seeking the dismissal of certain claims and parties based, in part, due to lack of standing. On July 16, 2004, plaintiffs filed a motion for leave to file an amended complaint, seeking to assert RICO violations.
