Business Highlights

Membership: Total fully insured commercial membership ended the quarter at 1.40 million members compared to 1.43 million members at the end of December 2003. The decline in fully insured commercial membership during the quarter was in line with management’s estimates. Medicare membership was 70,400 at the end of the quarter.

Premium Revenue: Premium revenue increased 5.6% in the first quarter to $1.38 billion from $1.31 billion in the first quarter of 2003. Commercial premiums increased 5.4% to $1.22 billion from $1.16 billion in the first quarter of 2003. During the first quarter of 2004 commercial premium yields increased approximately 9.9% over the prior year quarter. Commercial member months declined 4.1% for the quarter compared to the 2003 period. Medicare premiums were $167.1 million in the first quarter of 2004, compared to $155.4 million in the first quarter of 2003.

Investment and Other Income, net: Investment and other income, net, was $24.1 million in the first quarter of 2004, compared to $31.6 million in the first quarter of 2003. Realized gains for the quarter were $4.9 million in 2004, compared to $13.7 million in 2003. The net pre-tax yield on the Company’s investment portfolio was approximately 3.0% for the first quarter of 2004, compared to approximately 3.6% in the first quarter of 2003.

Health Care Services Expense: Health care services expense was $1.118 billion in the first quarter of 2004, compared to $1.034 billion in the first quarter of 2003. The first quarter of 2004 includes approximately $0.5 million of net favorable medical reserve estimate changes from prior periods compared to approximately $7.1 million in the first quarter of 2003. Commercial per member per month (PMPM) medical costs for the first quarter of 2004 increased approximately 11.8% compared to the 2003 first quarter. This increase reflects the reported PMPM commercial medical costs adjusted for net favorable development of commercial medical reserves of approximately $3.3 million and $8.0 million in the first quarter of 2004 and 2003, respectively, and the impact of one additional business day in the first quarter of 2004. Adjusting for the additional business day, commercial PMPM medical costs increased by approximately 10.7%. This increase was in line with management’s estimates for the quarter and is consistent with management’s estimate of a full year commercial PMPM medical trend between 9% and 10%.

The previously reported first quarter 2003 commercial PMPM medical costs increased only 8.4% over the first quarter of 2002, creating an atypical point of comparison for the current quarter’s results. The 2003 first quarter PMPM commercial medical cost increase was lower than expected at that time as a result of several one-time events affecting utilization in that quarter. The remaining three quarters of 2003 had higher medical cost trends and represent more normalized run rates for year-over-year analysis. Full year 2003 PMPM commercial medical cost trends were approximately 9.4%.

Marketing, General and Administrative (MG&A) Expenses: MG&A expenses were $147.3 million, resulting in an administrative loss ratio of 10.6% for the first quarter of 2004, compared to $142.3 million and a 10.8% administrative loss ratio in the first quarter of 2003. As a result of business mix changes and higher premium tax rates, broker commissions and premium taxes accounted for $50.8 million, or 34.5%, of total MG&A expenses for the first quarter of 2004, compared to $45.7 million, or 32.1%, of MG&A expenses in the first quarter of 2003. Excluding the increases in broker commissions and premium taxes, remaining MG&A expenses were essentially flat compared to the first quarter of 2003. (All dollar amounts and percentages cited in this paragraph for 2003 exclude the litigation charge for settlement presented in the accompanying income statement.)

Medical Costs Payable: Medical costs payable were $692.9 million as of March 31, 2004 compared to $671.5 million as of December 31, 2003. The $21.4 million increase during the quarter was primarily due to an increase in IBNR and unpaid claims reserves of $21.1 million. Days claims in medical costs payable ended the quarter at approximately 58 days, consistent with the level at December 31, 2003.

Cash Flow: Cash flow from operations was $65.1 million in the first quarter of 2004, compared to $114.1 million in the first quarter of 2003. Cash flow from operations for the first quarter of 2004 and 2003 includes only two months of Medicare premium receipts. Proforma for the January Medicare premiums received in December of each prior year, operating cash flows would have been $54.2 million and $50.2 million higher in 2004 and 2003, respectively. The decrease in operating cash flow from the prior year quarter was primarily due to the timing of income tax payments, increases in medical costs payments and the funding of certain accrued expenses. Net income for the first quarter of 2003 included a $45 million non-cash charge for litigation settlement.

Parent Cash Balances: Parent company cash and investments totaled $433.5 million at March 31, 2004, compared to $369 million at December 31, 2003. The increase during the quarter was primarily due to dividend receipts from regulated subsidiaries, income tax transfers from subsidiaries in excess of amounts due to taxing authorities and proceeds from stock option exercises. The Company currently has a $50 million dividend request under review by New York regulators.

Share Repurchase Program: As a result of the proposed merger between the Company and a wholly owned subsidiary of UnitedHealth Group, the Board of Directors of Oxford has terminated the Company’s share repurchase program. The Company did not repurchase any shares in the first quarter of 2004. The Company repurchased 23.8 million shares for $757.2 million since the inception of its share repurchase program in the third quarter of 2001.

Quarterly Dividend: The Company will pay a quarterly cash dividend of 10 cents per share on April 27, 2004 totaling $8.2 million, to shareholders of record as of April 12, 2004. The Company does not anticipate declaring any additional quarterly dividends at this time due to the proposed merger.

Management believes that the presentation of run rate earnings provides useful information to investors regarding the Company’s results of operations because such presentation facilitates the period-to-period comparison of operating performance by eliminating charges for settlement of the 1997 securities class action litigation, which charges are unrelated to current period operating performance, and by eliminating, among other things, the current period impact of changes to the Company’s estimates of prior period medical cost reserves. Run Rate Adjustments for the Quarters Ended March 31, 2004 and 2003 During the first quarter of 2004, the Company had net favorable prior period reserve adjustments (“PPRAs”) of medical costs of approximately $0.5 million, compared to approximately $7.1 million in the first quarter of 2003. These PPRAs had a nominal $0.01 per share effect on reported net earnings for the first quarter of 2004 and increased first quarter 2003 earnings by $0.05 per share.

Selected Trends and Financial Statistics Commercial premium revenues increased $62 million over the first quarter of 2003. Commercial premium yields, net of product mix and benefit changes, increased approximately 9.9% over the first quarter of 2003. Medicare premiums increased $11.7 million over the first quarter of 2003 as a result of the mix of membership and increased reimbursement rates. Commercial per member per month (PMPM) medical costs for the first quarter of 2004 increased approximately 11.8% compared to the 2003 first quarter. This increase reflects the reported PMPM commercial medical costs adjusted for net favorable development of commercial medical reserves of approximately $3.3 million and $8.0 million in the first quarter of 2004 and 2003, respectively, and the impact of one additional business day in the first quarter of 2004. Adjusting for the additional business day, commercial PMPM medical costs increased by approximately 10.7%. This increase was in line with management’s estimates for the quarter and is consistent with management’s estimate of a full year commercial PMPM medical trend between 9% and 10%. The previously reported first quarter 2003 commercial PMPM medical costs increased only 8.4% over the first quarter of 2002, creating an atypical point of comparison for the current quarter’s results. The 2003 first quarter PMPM commercial medical cost increase was lower than expected at that time as a result of several one-time events affecting utilization in that quarter. The remaining three quarters of 2003 had higher medical cost trends and represent more normalized run rates for year-over-year analysis. Full year 2003 PMPM commercial medical cost trends were approximately 9.4%. Exhibit 5 OXFORD HEALTH PLANS, INC.
