Towers Watson Merger with Willis Group

Summary of Tax Consequences for Individual U.S. Stockholders and U.S. Holders of Equity Incentives

This document includes a summary of the U.S. federal income tax consequences to individual U.S. stockholders and U.S. owners of certain equity awards of Towers Watson & Co. (“Towers Watson”) as a result of the merger between Towers Watson and Willis Group Holdings Public Limited Company (“Willis”). This document also includes examples illustrating how to calculate, for U.S. federal income tax purposes, taxable gains and losses on the merger and the tax basis of the Willis shares received in the merger. The examples apply to individuals who are citizens or residents of the United States, purchased all of their Towers Watson shares for cash (or received them as compensation) and hold those shares as a capital asset (generally, for investment purposes). The examples do not address any special tax rules that may apply, nor do they address the consequences of any state, local or foreign tax laws.

You should refer to registration statement on Form S-4 filed by Willis with the SEC on August 21, 2015, as it may be amended from time to time, for a summary of the material U.S. federal income tax consequences of (i) the merger and the Towers Watson pre-merger special dividend to holders of Towers Watson shares and of the ownership and disposition of Willis shares received by such holders upon the consummation of the merger and (ii) the reverse stock split Willis expects to effect after the merger to holders of Willis shares.

THIS DOCUMENT IS NOT MEANT TO PROVIDE YOU WITH TAX ADVICE. YOUR TAX CONSEQUENCES DEPEND ON YOUR INDIVIDUAL CIRCUMSTANCES AND COULD DIFFER SIGNIFICANTLY FROM THOSE IN THE EXAMPLES SET FORTH HEREIN. YOU SHOULD CONSULT YOUR OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO YOU IN LIGHT OF YOUR OWN TAX CIRCUMSTANCES.

U.S. Towers Watson Stockholders1

Summary

In the merger, Towers Watson stockholders (including holders of Towers Watson restricted stock that has vested) will receive 2.6490 ordinary shares of Willis for each share of Towers Watson stock they own. If this exchange ratio would result in a Towers Watson stockholder receiving fractional shares of Willis, he or she instead will receive cash in lieu of such fractional shares.

A U.S. stockholder generally will recognize gain or loss equal to (i) the sum of the fair market value of (x) the Willis ordinary shares received in the merger and (y) any fractional Willis ordinary shares that such Towers Watson stockholder would otherwise have been entitled to receive in the merger, less (ii) the stockholder’s aggregate tax basis in his or her Towers Watson common stock. Such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if the stockholder held the Towers Watson common stock for more than one year at the effective time of the merger. Gain or loss must be calculated separately for each block of Towers Watson common stock if blocks of Towers Watson common stock were acquired at different times or for different prices. The deductibility of capital losses is subject to limitations.

A U.S. stockholder’s aggregate tax basis in the Willis ordinary shares received in the merger will generally equal the fair market value of such Willis ordinary shares at the effective time of the merger, and the holder’s holding period for such Willis ordinary shares will begin on the day after the merger.

 

 

1  Note: This section does not apply to restricted stock that has not yet vested (and for which the holder has not made an election under Section 83(b) of the Internal Revenue Code). This section also does not apply to options to purchase Towers Watson common stock or Towers Watson restricted stock units. The treatment of unvested restricted stock, options to purchase Towers Watson common stock and Towers Watson restricted stock units is discussed in “U.S. Holders of Towers Watson Options, Restricted Stock and Restricted Stock Units” below.

It is possible that the IRS may seek to re-characterize the merger in a manner that would require U.S. stockholders with a loss on their Towers Watson common stock to defer the recognition of such loss until a taxable disposition of the Willis ordinary shares received in exchange for the Towers Watson common stock. U.S. stockholders with a gain on their Towers Watson common stock would still be required to recognize any such gain for U.S. federal income tax purposes as described above. U.S. stockholders holding their Towers Watson common stock at a loss are encouraged to consult their tax advisors

Towers Watson stockholders also will receive a special distribution prior to the merger. This distribution will be taxed as a dividend.

Steps to Calculate Gain or Loss

If the tax treatment described above is applicable to you, you generally will calculate your taxable gain or loss on the merger and the tax basis of the Willis shares you receive in the merger as described below. If you own multiple blocks of Towers Watson stock purchased at different share prices (or multiple blocks of restricted stock that vested at different times), you will calculate your gain on a block-by-block basis.

 

    Step 1: Calculate the Original Cost Basis of the Block of Towers Watson Shares.

Your cost basis generally equals the amount you paid for your block of Towers Watson shares. The cost basis of any vested restricted stock you own equals the fair market value of such stock at the time of vesting (or at the time of the award, if you made an election under Section 83(b) of the Internal Revenue Code with respect to such restricted stock).

 

    Step 2: Calculate the Total Consideration Received in the Merger for such Block of Shares.

Your total merger consideration generally will equal the fair market value of the Willis shares (including any fractional shares) that you receive in the merger in exchange for such block of shares.

 

    Step 3: Calculate the Taxable Gain or Loss in the Merger on such Block of Shares.

Your gain or loss equals (1) your total merger consideration (as determined in Step 2), minus (2) your cost basis in the Towers Watson shares (as determined in Step 1).

 

    Step 4: Calculate the Total Basis in New Willis Shares Received in Exchange for such Block of Shares.

Your total basis in the Willis shares received in the merger (including any fractional shares) in exchange for such block of shares generally will equal the fair market value of the Willis shares (including any fractional shares) that you receive in the merger.

 

    Step 5: Calculate the Taxable Gain or Loss Recognized on any Fractional Shares Received in Exchange for such Block of Shares.

Your gain or loss on the receipt of cash in lieu of any fractional Willis shares will equal (1) the cash you receive in exchange for the fractional shares, minus (2) your basis in the fractional shares (i.e. the fair market value of the fractional shares multiplied by the number of fractional shares).

 

    Step 6: Calculate the Total Basis in Remaining Willis Shares Received in Exchange for such Block of Shares.

Your total basis in the remaining Willis shares will equal (1) your basis in the Willis shares received in the merger (including the fractional shares) in exchange for such block of shares (as determined in Step 4), minus (2) your basis in the fractional shares (as determined for purposes of Step 5).

Examples

The following two examples illustrate the calculations described above. In each example, it is assumed that you own 100 shares of Towers Watson common stock at the time of the merger. It is also assumed, for purposes of calculating the total consideration received in the merger (Step 2), that the fair market value of any Willis shares received in the merger is $42 per share.

In each example, you would be entitled to approximately 264.90 Willis ordinary shares (100 Towers Watson shares multiplied by the 2.6490 exchange ratio). In lieu of the 0.90 fractional share, you would receive a cash payment of approximately $37.80 (0.90 fractional shares multiplied by $42 share price), leaving you with 264 Willis ordinary shares.

The examples differ as to the original cost basis in the Towers Watson shares. In Example 1, you are assumed to have an original cost basis of $50 per Towers Watson share. In Example 2, your basis is assumed to be $130 per share.

Example 1

 

Step 1: Original Cost Basis of Towers Watson Shares

  

100 shares x $50 / share

   $ 5,000.00   

Step 2: Total Consideration Received in Merger

   $ 11,125.80   

Step 3: Taxable Gain or Loss in the Merger

Step 5: Taxable Gain or Loss on Fractional Share

  

Cash Paid in Lieu of Fractional Share (0.90 x $42.00)

   $ 37.80   

Less: Basis Attributable to Fractional Share (0.90 / $42.00)

     (37.80
  

 

 

 

Basis in Remaining Willis Shares (264 shares)

   $ 11,088.00   
  

 

 

 

Per Share Basis ($11,088 / 264)

   $ 42.00   

In this example, you would report a total taxable gain from the merger of $6,125.80 and you would have an aggregate tax basis in the 264 shares of Willis stock that you continue to hold of $11,088.

In this example, you would report a total taxable loss from the merger of $1,874.20 and you would have an aggregate tax basis in the 264 shares of Willis stock that you continue to hold of $11,088.

U.S. Holders of Towers Watson Options, Restricted Stock and Restricted Stock Units2

In the merger, each option to purchase shares of Towers Watson common stock will be converted into an option to acquire Willis ordinary shares. Generally, the number of Willis ordinary shares that can be acquired by an option will be determined by multiplying the number of shares of Towers Watson stock that could be acquired immediately prior to the merger by the exchange ratio of 2.6490 ordinary shares of Willis for each share of Towers Watson stock (with the number of shares rounded down to the nearest whole number) and the exercise price will be determined by dividing the exercise price immediately prior to the merger by the exchange ratio of 2.6490 (rounded up to the nearest whole cent). Each option to acquire Willis ordinary shares will be subject to the same terms and conditions that applied to the corresponding Towers Watson stock option immediately prior to the merger.

In the merger, each outstanding award of restricted stock units will be converted into a restricted stock unit award corresponding to Willis ordinary shares. The number of Willis ordinary shares to which such award will apply will be determined based on the exchange ratio of 2.6490 ordinary shares of Willis for each share of Towers Watson stock (rounded down to the nearest whole number). Generally, each award of restricted stock units will be subject to the same terms and conditions that applied to such award immediately prior to the merger; provided that, for restricted stock units that vest based on performance, the number of shares will be determined based on the higher of the target level of performance or actual performance through the most recent practicable date prior to the closing, and will thereafter vest on the basis of time only.

In addition, in the merger, each outstanding award of unvested restricted stock will be converted into restricted Willis ordinary shares. The number of restricted Willis ordinary shares will be determined based on the exchange ratio of 2.6490 ordinary shares of Willis for each share of restricted Towers Watson stock (rounded down to the nearest whole number). Generally, each award of restricted stock will be subject to the same terms and conditions that applied to such award immediately prior to the merger.

U.S. holders of Towers Watson options, unvested restricted stock and restricted stock units will not be subject to U.S. income tax at the time of the merger. Rather, such U.S. holders generally will be subject to U.S. income tax when they exercise the options, when the restricted stock vests or when the restricted stock units are settled, whichever is applicable.

 

2  Note: This section does not apply to restricted stock that has vested, or for which the holder has made an election under Section 83(b) of the Internal Revenue Code. The treatment of such restricted stock is discussed above in “U.S. Towers Watson Stockholders.”
