Investments

The Company utilizes the equity method of accounting for investments in entities where it does not have control but has the ability to exercise significant influence over the investee’s operating and financial policies. The Company considers investments in publicly traded securities for which it does not have significant influence as available-for-sale. Available-for-sale securities are carried at fair value with changes in fair value recorded net of tax in other comprehensive income. As of September 30, 2014, the Company owned 1.59 million shares of Hydrogenics Corporation (Hydrogenics), a publicly traded company that supplies hydrogen generators and hydrogen-based power modules and fuel cells for various uses. During the nine months ended September 30, 2014, the Company reduced its ownership in Hydrogenics and is no longer considered to have significant influence over the investee’s operating and financial policies and , as a result, the Company changed its method of accounting from the equity method to classifying the investment as available-for-sale. The Company’s share of earnings and losses for the nine months ended September 30, 2014 and the three and nine months ended September 30, 2013 was immaterial.

As of September 30, 2014, the cost basis of the investment in Hydrogenics was $1.2 million, the fair value was $26.8 million and the unrealized pretax gains recorded in accumulated other comprehensive income were $25.6 million. The Company did not hold any investments that were classified as available-for-sale as of December 31, 2013. As of December 31, 2013 the carrying value of the Hydrogenics investment, accounted for under the equity method, was $3.1 million. Investments are recorded in other noncurrent assets on the Condensed Consolidated Balance Sheets.

During the three and nine months ended September 30, 2014, the Company sold 0.1 million and 0.6 million shares of Hydrogenics common stock, respectively, and received proceeds of $2.1 million and $9.2 million, respectively, (included in other investing activities on the Condensed Consolidated Statements of Cash Flows). Using the average cost method to value the shares sold, the Company recorded pretax realized gains of $2.0 million and $8.8 million, respectively, for the three and nine months ended September 30, 2014 (recorded in other income (expense), net on the Condensed Consolidated Statements of Operations and Comprehensive Income).
