As for the fourth quarter, revenues were $18.16 billion, slightly below analyst estimates of $18.23 billion. Year-over-year comparisons are not meaningful, since the company made the significant PacifiCare acquisition in late 2005. Operating margins for the quarter increased to 11%, helped by the seasonality of Medicare Part D, which lowered the medical loss ratio (MLR). The MLR is analogous to cost of goods sold for other businesses. UnitedHealth used a non-GAAP presentation to normalize the seasonality of Medicare D. The normalized 81.4% MLR for the fourth quarter was more in line with the full year's 81.2% ratio.
On the negative side, there was an increase in the MLR specific to the UnitedHealthcare segment. While no trend has been established yet, any signs that the commercial MLR is increasing could hamper future profitability and subsequent cash flows, especially given the cyclical nature of the business. However, even with the increased overall MLRs, the company is still generating significant cash flows.
Cash flow from operations was $1.6 billion for the quarter and $6.5 billion for the year. (A free cash flow estimate is unavailable, since a cash flow statement wasn't provided.) Because UnitedHealth is unable to use its excess cash for share buybacks until it's current with the SEC, the health insurer also benefited from increased investment income due to the growing cash balance. Moving forward, the challenge will be to maintain operating cost and underwriting disciplines so that these cash flows remain healthy.
If UnitedHealth, under the leadership of CEO Stephen Hemsley, begins achieving its 2007 targets, I think the company will manage just fine and investors will begin to look forward, not backward. With the diversity of UnitedHealth's operations both geographically and across business types, the company should be able to navigate the upcoming challenges, such as California's new proposed universal health-care plan, better than most of its smaller peers such as Aetna
