Equity in Income of Unconsolidated Affiliates Beginning with our fiscal year ended May 31, 2007, we began purchasing shares of Kemrock Industries and Exports Limited (“Kemrock”) common stock. Kemrock is one of India’s leading manufacturers of high performance reinforced polymer composites, and is also part of a strategic alliance with certain of our subsidiaries for licensed manufacturing and supply of molded and pultruded gratings. By May 31, 2011, we had acquired a total of approximately 3.2 million shares of Kemrock common stock, for an accumulated cost approximating $24.2 million, which represented approximately 18% of Kemrock’s outstanding shares at that time. Our investment in Kemrock common stock had been classified in other long-term assets on our balance sheet and included with available-for-sale securities, which are carried at fair value based on quoted market prices. During fiscal 2012, we purchased approximately 870,000 additional shares of Kemrock common stock, which increased our ownership to 23% of Kemrock’s outstanding shares. Also during fiscal 2012, we entered into a GDR Purchase Agreement with Kemrock, whereby we purchased from Kemrock 693,072 GDRs of Kemrock for an aggregate purchase price of approximately $7.2 million. We account for our investment in the Kemrock GDRs as common stock equivalents within our total investment in Kemrock. Due to the presumption under GAAP that an entity with an ownership percentage greater than 20% has significant influence, and no other factors would refute that presumption, we changed our accounting for this investment to the equity method. Adjustments are made to our investment in order to recognize our share of Kemrock’s earnings as they occur, rather than as dividends or other distributions are received. Any changes in our proportionate share of the underlying equity of Kemrock, which could result from their issuance of additional equity securities, are recognized as increases or decreases in shareholders’ equity, net of any related tax effects. As discussed in Note 2, the economy and financial markets in India have experienced significant deterioration in recent months, including a devaluation of the Indian rupee versus the U.S. dollar. Additionally, the market value of shares of Kemrock common stock declined significantly, from 531.0 rupees per share as of May 31, 2012 to 56.70 rupees per share as of November 30, 2012. The majority of the decline in the market value of Kemrock shares began to occur during the month of August 2012. As a result of these factors, we determined that it was appropriate to record an impairment loss during the three and six month periods ended November 30, 2012 of approximately $10.1 million and $42.2 million, respectively, on our equity method investment. The loss is classified in other (income) expense, net in our Consolidated Statements of Income. Our investment in Kemrock is reported in our Consolidated Balance Sheet at its adjusted carrying value and classified as a long-term asset. Our investment in Kemrock had no carrying value at November 30, 2012 and a carrying value of $42.2 million at May 31, 2012.
