Equity Earnings of Unconsolidated Affiliates, Net of Tax and Net Income Attributable to Noncontrolling Interests	EQUITY EARNINGS OF UNCONSOLIDATED AFFILIATES, NET OF TAX AND NET INCOME ATTRIBUTABLE TO NONCONTROLLING INTERESTS Equity earnings of unconsolidated affiliates, net of tax Equity earnings of unconsolidated affiliates, net of tax, represent the Company’s share of earnings of affiliates in which the Company does not exercise control and has a 20 percent or more voting interest. Investments in such affiliates are accounted for using the equity method of accounting. If the fair value of an investment in an affiliate is below its carrying value and the difference is deemed to be other than temporary, the difference between the fair value and the carrying value is charged to earnings. The Company had an equity interest in two such affiliates as of July 31, 2017. Equity earnings of unconsolidated affiliates, net of tax, were $0.3 million for the three and nine months ended July 31, 2017. Equity earnings of unconsolidated affiliates, net of tax, were $0.8 million for the three and nine months ended July 31, 2016. There were no dividends received from the Company's equity method affiliates for the three and nine months ended July 31, 2017 and 2016. Net income attributable to noncontrolling interests Net income attributable to noncontrolling interests represent the portion of earnings from the operations of the Company’s consolidated subsidiaries attributable to unrelated third party equity owners that were deducted from net income to arrive at net income attributable to the Company. Net income attributable to noncontrolling interests for the three months ended July 31, 2017 and 2016 was $3.6 million and $0.3 million, respectively. Net income attributable to noncontrolling interests for the nine months ended July 31, 2017 and 2016 was $10.1 million and $2.6 million, respectively.
