The following is a letter to Trane shareholders that will be included in the Trane Annual Report on Form 10-K sent to Trane shareholders. The letter will also be posted in Trane’s website at www.trane.com.



To Our Shareowners:

It’s been quite a year… and will be quite a future

Few companies have ever had a year like we had in 2007.

We began the year as American Standard Companies and in the space of just 11 months separated our company’s three businesses:



Vehicle Control Systems – On July 31 we spun off this global leader in control systems for commercial vehicles and passenger cars to our shareowners as an independent, publicly held company called WABCO.



Bath and Kitchen – On Oct. 31 we sold this global business — the one many people associate with the American Standard name — to Bain Capital Partners, LLC.



Air Conditioning Systems and Services – Our largest business became our exclusive focus. On Nov. 28 we renamed the company Trane to reflect that focus and began trading on the New York Stock Exchange under the symbol TT.

And if that wasn’t enough …

In December we agreed to sell Trane to Ingersoll Rand, which will create a new company of even greater size, strength and potential. Under terms of the agreement, our shareowners will receive $36.50 in cash and .23 shares of Ingersoll Rand stock for every Trane share they hold. We expect the sale to be completed in the second quarter of 2008.

While these changes were generating new shareowner value, our people remained focused on business. WABCO had a record year despite a significant decline in North American truck builds. Bath and Kitchen made great strides in rebuilding profitability around the world. And Trane delivered a year of record results that expanded our global leadership in Air Conditioning Systems and Services.

Acting from a position of strength

Some companies separate their businesses out of frustration. We acted from a position of strength and with conviction that we were creating a bright future for our businesses and customers as well as our employees and shareowners. Our board of directors and our leadership were convinced and continue to believe that this was the right thing to do and that this was the right time to do it.

While the three businesses of the former American Standard Companies were diverse, they shared a company-wide commitment to continuous improvement dating back to when the company went public in 1995. That commitment was backed by investment in new products, new technology, productivity improvements, quality and safety initiatives, brand building and talent development.

By 2007 our three businesses had attained the size, global reach, industry prominence and leadership talent to prosper as separate companies. That made us confident we could separate them into focused, better understood businesses creating greater shareowner value than the existing structure.

Untying their corporate connections and arranging for three separate launches was a complex process. Most important, all three businesses maintained their momentum, undistracted by the separation process. It’s a tribute to our leadership and people that we completed the separation so quickly and so well.

Trane’s performance in 2007

It was a very good year for Trane and a proud year for our 29,600 people. The company generated $7.45 billion in sales resulting in a 10.2 percent year-over-year increase for continuing operations. We reported 2007 full-year income from continuing operations of $1.96 per diluted share on a GAAP basis, up 5 percent from $1.87 in 2006. On an adjusted basis, income from continuing operations was $1.98 per diluted share, up 14 percent from $1.73.

We had record sales in global commercial equipment systems ending the year with a healthy equipment backlog of about $967 million, up 8 percent in local currencies from the end of 2006. We also had particularly strong growth in services, where we broke the $1 billion mark in the Americas. Overall, about 29 percent of our total company revenue came from parts, services and solutions.

The large and growing installed base of Trane equipment and systems continues to present us with a powerful opportunity to increase service revenues by doing more for customers over the life of their buildings. We’ve gone after that opportunity aggressively in recent years. Services have the appeal of being less cyclical than equipment sales because systems need to be serviced in hot and cold weather as well as in hot and cold economies.

Trane’s growth in services is an important part of our overall transition from an equipment business to a global leader in providing integrated heating, ventilation and air conditioning (HVAC) systems, services and solutions. In 2007 we built on our leadership position by providing a broad range of commercial and residential customers with everything from complete HVAC systems for skyscrapers to air cleaning systems for homes.

The slowdown in North American new home construction created a challenging year for residential systems, although we were well positioned for it because more than 80 percent of our residential sales are for renovation and replacement. We couldn’t control the pace of the economy so we concentrated on those things we could control: increasing productivity, implementing cost controls and, most important, developing new products based on real customer needs. For example, we introduced the innovative XV95 home furnace to the residential market in 2007. It is generating a surge of new sales and is the most energy-efficient gas home furnace available.

The increasing demand for environmentally responsible products like the XV95 represents a promising growth opportunity for us, and we are working hard to make Trane synonymous with energy efficiency and green building technology. In 2007 we provided customers with performance contracts that guaranteed specific energy efficiency gains from the systems we sold and serviced. We were proud to be selected by the Clinton Climate Initiative for a project to reduce greenhouse gas emissions in 40 of the world’s major cities. And the U.S. Environmental Protection Agency honored our CenTraVac™ with the “Best of the Best Award” as the most energy-efficient large chiller system in the market.

A new opportunity with Ingersoll Rand

As 2007 came to a close, we reached agreement with Ingersoll Rand to acquire Trane. Both our companies have refocused their portfolios. The addition of Trane will make Ingersoll Rand a $17 billion diversified industrial company, and $11 billion of that revenue will come from climate control technologies.

Trane’s commercial and residential HVAC business will combine with Ingersoll Rand’s solid position in refrigeration systems for transport, storage and food store displays. Together Trane and Ingersoll Rand will form a powerful, more global combination offering climate control systems and services for the comfort of people and the efficiency of business processes, as well as for the preservation of our food supply. We believe there are particularly strong opportunities for our combined companies in emerging markets like India and China, and in those industries where HVAC and refrigeration needs intersect.

Over the long term we expect to identify new revenue streams utilizing the resources of both companies. We both bring unique resources to the party as well as shared attributes like premium global brands, efficient manufacturing, sophisticated engineering, and innovative research and development. The combination creates potential for immediate savings in areas like purchasing, where the estimated $8.5 billion annual spending outlay of the two companies will create new opportunities with suppliers. In addition, we expect to realize cost savings through the integration of corporate functions and shared use of facilities. Teams from both companies are already working together on integration planning.



What to expect next

The acquisition requires approval by government regulatory agencies and you, our shareowners. We expect to receive approval shortly from all of the government regulatory agencies and to ask for your vote in the second quarter of this year. Our board of directors has voted unanimously to recommend the acquisition. When it’s time for you to vote, you will receive a ballot and proxy statement in the mail. You can vote by mail, phone or online. A special meeting of shareowners will be convened to record the votes and, if approved, the acquisition will be completed.

2008 and beyond

It’s been quite a year in what has been a rewarding journey for our company. It’s been my privilege and pleasure to lead our company and participate in that journey over the past eight years. As we move forward, our future looks extremely bright. Ingersoll Rand and Trane together are well positioned to use the size, strength and operational effectiveness of a $17 billion industrial company to compete successfully in the global marketplace. I am convinced that this powerful combination holds strong potential for the customers, employees and shareowners of Trane and Ingersoll Rand. So, yes …

It’s been quite a year … and will be quite a future.
