Subsequent Event- Business Combination

5. SUBSEQUENT EVENT- BUSINESS COMBINATION

On 29 February 2012, we entered into a definitive agreement with E.I. DuPont de Nemours and Co., Inc. to acquire their 50% interest in our joint venture, DuPont Air Products NanoMaterials LLC (DA NanoMaterials). DA NanoMaterials' revenues for calendar year 2011 were approximately $90.

The acquisition closed on 2 April 2012 for approximately $150, subject to working capital adjustments, and was accounted for as a business combination. We will consolidate DA NanoMaterials results beginning in the third quarter of 2012 within our Electronics and Performance Materials business segment. Prior to the acquisition date, we accounted for our 50% interest in DA NanoMaterials as an equity-method investment. An after-tax gain in the range of $45-$55 is expected to be recognized in the third quarter as a result of revaluing our previously held equity interest before the business combination.
