NEW EMPLOYEE QUESTIONS AND RESPONSES FOR PUBLICATION ON JAN. 14, 2008

 

  1. New! (1/14/08) Who provides/underwrites extended warranties for Ingersoll Rand’s current products? Does Ingersoll Rand have an extended warranty department/division? Can you discuss future plans for handling extended warranties for both existing Ingersoll Rand products and Trane and American Standard brand HVAC equipment?

We do not expect any changes to the Trane/American Standard extended warranty programs prior to the closing of the transaction. It is too early to say what might happen after the closing. This will be addressed by integration teams which have yet to be formed.

 

  2. New! (1/14/08) Will we retain the American Standard HVAC brand?

Yes. The American Standard brand remains a meaningful and important part of our HVAC business. The overall growth strategy and vision for the brand is to reach $1 billion in sales by the year 2010. Therefore, the business has made the commitment to invest in people, product and brand awareness to help accomplish this goal.

 

  3. New! (1/14/08) Are we permitted to contact our counterparts at Ingersoll Rand?

DO NOT contact your counterpart or anyone at Ingersoll Rand unless you are involved in an authorized integration team. We understand that your counterparts at Ingersoll Rand will be instructed, and will be expected to not contact Trane employees except through authorized integration teams. Both companies’ leaders agree that, for the vast majority of employees, time is best spent focusing on “business as usual” and meeting or exceeding our operating plans. Until the acquisition closes, random phone calls, meetings or requests for information outside of authorized integration activities are an unnecessary distraction for both businesses, or worse, could create problems for our business with regulatory authorities. It is extremely important that Trane continues to operate as a stand-alone business until the acquisition is completed.

 

  4. New! (1/14/08) What has Ingersoll Rand identified as areas for the $300 million in synergies? (Will follow current Q. 7 under “Business Decision”) Waiting for confirmation of this new response.

During its analyst call on Dec. 17, Ingersoll Rand stated that it anticipates annual run rate savings of $300 million pre tax by 2010. These savings will be pretty evenly divided between selling, general and administrative (SG&A) expense and gross margin. Cost of goods will be lower through the impact of supplier rationalization, procurement leverage on a combined $7.5 billion of material spend, global sourcing, and manufacturing initiatives that generate efficiency and productivity improvement, such as Lean Six Sigma. Ingersoll Rand sees solid cost efficiencies to be gained across the combined entity’s $3 billion of SG&A structure, which will include the integration of the two

corporate staffs and improved productivity across global administrative operations. An achievable target is $125 million (pre-tax) for 2008. Ingersoll Rand’s additional revenue synergies could result from market and service expansion, cross-selling and global growth, although those amounts have not yet been quantified.

 

  5. New! (1/14/08) How will the Ingersoll Rand acquisition affect independently owned commercial offices?

The contractual relationships between Trane and independently owned commercial sales offices are not affected by the acquisition of Trane by Ingersoll Rand.

 

  6. New! (1/14/08) Has Ingersoll Rand acquired other companies whose shared services functions and/or locations were retained?

Ingersoll Rand has not previously acquired a business with substantial shared-services capabilities. However, Herb Henkel has stated publicly that the combination of systems, processes and resources that will best meet the needs of the organization on a go-forward basis will be retained.

 

  7. New! (1/14/08) What is Ingersoll Rand’s approach to wellness? How does it compare with LifeSteps?

While Ingersoll Rand offers some wellness benefits, it does not currently offer a program as extensive as LifeSteps. Trane believes in the benefits of LifeSteps, and we plan to share details of our program as part of the integration process.

 

  8. New! (1/14/08) When will employees be able to access the 70-percent discount on Schlage and other Ingersoll Rand products, as Herb Henkel mentioned during our town hall meeting?

Whatever product discount programs that are now in place for current Ingersoll Rand employees will be made available to Trane employees effective with the closing date of the acquisition. More details will be provided closer to that time.

NOTE: The transaction is subject to a vote of the Trane stockholders and requires registration of the shares of Ingersoll-Rand to be issued in the merger. Accordingly, written communications regarding the transaction may be deemed to be solicitations of proxies or an offering prospectus and require the following legends.
