Since the fourth quarter of fiscal 2010, the Company has acquired a number of businesses within the lighting and controls market, as discussed below. None of the business combinations—individually or in the aggregate—represented a material transaction as compared to the Company’s financial condition, results of operations, or cash flows in any of the periods in which control was obtained. *Healthcare Lighting Acquisition* On May 12, 2011, the Company acquired for cash all of the ownership interests in Healthcare Lighting, a leading provider of specialized, high-performance lighting products for healthcare facilities. Based in Fairview, Pennsylvania, Healthcare Lighting exclusively focused on servicing the healthcare industry through the design and manufacture of medical lighting products meant to enhance the visual environment in healthcare settings. The Company expensed an immaterial amount of acquisition costs in current quarter earnings. The operating results of Healthcare Lighting have been included in the Company’s consolidated financial statements since the date of acquisition and are not material to the Company’s financial condition, results of operations, or cash flows. Preliminary amounts related to the acquisition are reflected in the Consolidated Balance Sheets as of May 31, 2011.
