About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F2: Disposed of pursuant to the Merger Agreement and by virtue of the Merger, in which each share of the Issuer's common stock, par value $0.01 per share ("Issuer Common Stock"), issued and outstanding immediately prior to the completion of the Merger was converted into the right to receive $53.81 in cash, without interest (the "Per Share Merger Consideration"), consisting of (i) $52.65 in cash, plus (ii) an additional amount in cash equal to $1.16, calculated in accordance with the Merger Agreement based on the per-share, after-tax value of the Issuer's equity interests in Evolent Health, Inc. Pursuant to the Merger Agreement and by virtue of the Merger, each share of common stock of Merger Sub outstanding immediately prior to the Merger was converted into one share of Issuer Common Stock, as the surviving corporation in the Merger, and constitutes the only outstanding shares of the Issuer.

F3: Represents restricted stock units (each, an "RSU") that were outstanding immediately prior to the Merger. By their terms, prior to the Merger, each RSU represented a contingent right to one share of Issuer Common Stock. Each RSU was assumed and converted into an equivalent UnitedHealth award denominated in shares of UnitedHealth common stock, on the same terms and conditions as were applicable immediately prior to the Merger, equal to the product of (i) the total number of shares of Issuer Common Stock subject to such awards, multiplied by (ii) 0.254270199, which represents the quotient obtained by dividing (A) the Per-Share Merger Consideration by (B) volume weighted average closing sale price of UnitedHealth common stock for the five full trading days ending on and including the third business day prior to the Merger (the "Equity Award Conversion Ratio"), with any fractional shares rounded down to the next lower whole number of shares.

F4: The RSUs vest in four equal installments on May 11, 2015; April 11, 2016; April 11, 2017; and April 11, 2018, unless deferred.

F5: The RSUs vest in four equal installments on May 10, 2016; April 10, 2017; April 10, 2018; and April 10, 2019, unless deferred. Upon vesting, each RSU is settled by the delivery of the underlying shares of common stock or payment of the current cash value of the vested shares, at the discretion of the Issuer.

F6: Each "Non-LTIP Option," which represents a non-qualified stock option other than an LTIP Option (as defined below) that is outstanding immediately prior to the Merger, whether vested or unvested, was assumed and converted into a non-qualified stock option to purchase a number of shares of UnitedHealth common stock, on the same terms and conditions as were applicable immediately prior to the Merger (except that any performance-based vesting conditions applicable to such option no longer apply), equal to the product of (i) the total number of shares of Issuer Common Stock subject to such option, multiplied by (ii) the Equity Award Conversion Ratio, with any fractional shares rounded down to the next lower whole number of shares. The exercise price per share of such option will be equal to the quotient obtained by dividing (A) the Per Share Merger Consideration by (B) the Equity Award Conversion Ratio, with any fractional cents rounded up to the next higher number of whole cents.

F7: The options to purchase the Issuer Common Stock become exercisable in two equal annual installments beginning on April 18, 2016.

F13: Each "LTIP Option," which represents a non-qualified stock option granted pursuant to the 2014 supplemental long-term incentive program that is not vested in accordance with its terms and outstanding immediately prior to the Merger, was assumed and converted into an option to purchase a number of shares of UnitedHealth common stock, on the same terms and conditions as were applicable immediately prior to the Merger, equal to the product of (i) the total number of shares of Issuer Common Stock subject to such option, multiplied by (ii) the Equity Award Conversion Ratio, with any fractional shares rounded down to the next lower whole number of shares, and with performance-vesting conditions equitably adjusted pursuant to the Merger Agreement to reflect the Merger.
