EX-99.1

Exhibit 99.1

To:          Employees with Equity Grants

From       Rob Ashe

We realize that employees that are holding Canadian dollar equity grants are concerned with the value of their vested equity given the current volatility of the Canadian dollar relative to the US dollar.  In order to alleviate these concerns and to ensure that employees remain focused and motivated on delivering value to our customers as we move through the acquisition phase, IBM has agreed to allow Cognos to institute a transition retention cash bonus program.  Under the program, cash bonuses to neutralize the effect of exchange rate fluctuations may be paid immediately prior to the closing of the acquisition of Cognos by IBM to those Cognos employees which meet the eligibility requirements described below.

Employees holding Canadian dollar denominated options or RSUs immediately prior to the closing which are to be cashed out under the terms of the plan of arrangement will be eligible for this program.  For each eligible employee, the bonus payment will be an amount (if positive) equal to:

(x)Cdn. $55.91(1) minus the Canadian dollar equivalent of US$58.00 (translated to Canadian dollars using the Noon Rate) on the business day prior to the closing date; multiplied by

(y)the number of Canadian dollar denominated vested options plus the number of Canadian dollar denominated vested RSUs, in each case, which are to be cashed out under the terms of the plan of arrangement; plus

(z)in the case of vested options, such amount as is necessary to compensate for the amount of tax preference that would have been otherwise received by such eligible employee had the payment been treated as an eligible stock option benefit.

(1) Cdn. $55.91 is US$58.00 translated to Canadian dollars using the noon buying rate that the Federal Reserve Bank of New York has certified for customs purposes in New York City for cable transfers payable in foreign currencies (the “Noon Rate”) on November 13, 2007 (which was $1.0375USD = $1.0000 Cdn)

This in effect will give employees holding Canadian dollar vested equity grants at the time of closing protection from deterioration of equity values from November 13, 2007 to the closing date as a result of exchange rate volatility.  If the Canadian dollar declines against the US dollar between November 13, 2007 and the closing date, no additional payments will be made.

Allowing Cognos to pay these bonuses and protect the equity value for employees holding Canadian dollar options and RSUs is another indication of IBM’s commitment to Cognos employees.

If you have any questions, please contact myself or Tom Manley.

Regards,

/s/ Rob Ashe
