Equity Q&As

 

Q. How does the transaction work?
A. Aon has offered $50 per share of Hewitt stock. Both Hewitt and Aon shareholders must approve the deal. We expect this to occur sometime in November.

 

Q. What will happen to my unvested Restricted Stock Units (RSUs)?
A. On the effective date the deal closes (anticipated sometime in November), all RSUs will become fully vested shares of Hewitt common stock.
A. These Hewitt common shares will then be paid out in a mix of cash and Aon stock. For each Hewitt share, you will receive consideration equal to $25.61 cash plus 0.6362 shares of Aon stock for each Hewitt share. The final value of your equity will fluctuate with the value of Aon stock.
A. The vesting of RSUs is a taxable event. As is the process for RSU vesting that has occurred in the past, a portion of the shares that vest will be withheld to cover the tax liability in the US and many countries. (Tax impact and withholding will vary based on the country in which you are located).
A. We are working with Aon along with Morgan Stanley Smith Barney to further define the process for converting Hewitt RSUs, including the timing thereof. More details will be communicated in the coming weeks.

 

Q. What will happen with my vested restricted stock units?
A. Between now and closing, as a Hewitt shareholder, you will have the opportunity to choose one of three considerations:
  1. Mix of $25.61 cash plus 0.6362 shares of Aon stock for each Hewitt share
  2. The same value paid in 100% cash
  3. The same value paid in 100% Aon stock
A. Shareholders that elect to receive 100% stock or 100% cash may be subject to a pro rata adjustment under certain circumstances that will affect the mix of consideration they receive but not the value. More details concerning the election process will be provided in the coming weeks.

 

Q. What will happen to my stock options?
A. On the effective date the deal closes, all unvested stock options will become fully vested and exercisable.
A. If you are a stock option holder, 100% of your outstanding Hewitt stock options must be converted to options to purchase Aon stock. The number of Aon options and their strike price will be adjusted in order to maintain the option spread immediately before and after the closing of the merger. In other words, if your Hewitt options have a $25,000 “in-the-money” value before the closing, they will have the same $25,000 “in-the-money” value after the closing. The accelerated vesting and conversion to Aon options are not taxable events.
A. We are working with Aon along with Morgan Stanley Smith Barney to further define the process for converting Hewitt stock options, including the timing thereof. More details will be communicated in the coming weeks.

 

Q. What will happen for the Band 6 Cash LTI program?
A. The Band 6 Cash LTI awards will become fully vested on the effective date the deal closes. Like RSUs, Cash LTI awards will be taxable. The administration of this process will be further defined with our plan record keeper and more details will follow in the coming weeks.

 

Q. Can I sell my stock between the announcement and the close?
A. As a general matter, the pending transaction, once announced, will not affect your ability to sell your stock. You will, however, continue to be subject to Hewitt’s general policies concerning stock sales, including blackout policies and general restrictions on sales, when you are in possession of material undisclosed information.

 

Q. What will happen to my FY10 annual bonus?
A. We expect that the transaction will close after Hewitt’s fiscal year and bonus measurement period has ended (September 30, 2010). Therefore, all current performance and bonus plans will remain in effect and performance against defined metrics and goals will be used to determine payouts for the current fiscal year.
