The restricted stock units will vest at a rate of 25% annually on February 3 from the years 2010 through 2013.
Amount does not include performance-based restricted stock units granted to the executive officer on February 23, 2009, as performance awards not tied to stock price are not derivative securities for purposes of Section 16 under guidance from the staff of the SEC.  The number of performance-based restricted stock units that the executive officer will receive will be determined at the end of the 3-year performance period and will be dependent upon the achievement of average EPS growth percentanges and average return-on-equity performance metrics approved by the Compensation and Human Resources Committee. The target number of performance-based restricted stock units is 19,231.  Amount does include shares acquired under UnitedHealth Group's Employee Stock Purchase Plan.
The stock appreciation rights vest at a rate of 25% annually on February 3 from the years 2010 through 2013.
