Item 1.01.—Entry into a Material Definitive Agreement

On June 5, 2006, United Technologies Corporation (“UTC”) entered into an agreement with the U.S. Department of Defense (“DoD”) to pay $283 million in settlement of litigation arising from a longstanding dispute concerning the acceptability of government cost accounting practices for engine parts produced by foreign companies under commercial engine collaboration programs at UTC’s Pratt & Whitney division. The litigation centered on the allocation of overhead costs between commercial and government programs. As previously reported in UTC’s periodic filings with the Securities & Exchange Commission, the litigation was initiated by Pratt & Whitney in 1996 and involved claims for the years 1984 through 2004. The Armed Services Board of Contract Appeals (“ASBCA”) ruled in Pratt & Whitney’s favor in 2001, but the U.S. Court of Appeals for the Federal Circuit reversed in 2003 and remanded the case to the ASBCA to determine the appropriate accounting. The U.S. Supreme Court declined to review that decision. Since January 1, 2005, Pratt & Whitney has used an alternative method of allocating overhead costs, which is based on the value added by Pratt & Whitney in the manufacturing process. This methodology has been approved by the government. UTC’s reserves relating to this litigation matter exceeded the settlement amount by approximately $0.05 per share. UTC anticipates restructuring charges over the course of 2006 to equal or exceed this difference. The DoD is a customer for Pratt & Whitney engines and aftermarket products and services, as well as for products and services at other UTC business units.

This Report on Form 8-K includes a “forward looking statement” concerning anticipated restructuring charges that is subject to risks and uncertainties. No specific plans for these additional restructuring charges have been determined at this time. Actual restructuring activities depend upon the level of acquisition activity and the availability of other restructuring and cost reduction opportunities. For additional information concerning restructuring, see UTC’s SEC filings as submitted from time to time, including but not limited to, the information included in UTC’s 10-K and 10-Q Reports under the headings “Business,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Cautionary Note Concerning Factors That May Affect Future Results,” as well as the information included in UTC’s Current Reports on Form 8-K.
