Noncontrolling Interest [Abstract] |
Redeemable Noncontrolling Interest | Redeemable Noncontrolling Interest During 2016, the 15% redeemable noncontrolling interest in ATI Flowform Products was purchased by ATI at the $12.1 million acquisition date carrying value, resulting in no remaining redeemable noncontrolling interest held in ATI Flowform Products as of December 31, 2017 and 2016. The previous holders of the 15% redeemable noncontrolling interest in ATI Flowform Products had a put option to require the Company to purchase their equity interest at a specified redemption value. The put option could not be separated from the noncontrolling interest, and the combination of a noncontrolling interest and the redemption feature required classification as redeemable noncontrolling interest in the consolidated balance sheet, separate from Stockholders’ Equity. The carrying amount of the redeemable noncontrolling interest approximated its maximum redemption value. Any subsequent change in maximum redemption value was adjusted through retained earnings. The adjustment to the carrying amount for the year ended December 31, 2015 reduced retained earnings by $0.3 million. The Company applied the two-class method of calculating earnings per share, and as such this adjustment to the carrying amount was reflected in earnings per share. The redeemable noncontrolling interest was $12.1 million as of December 31, 2015, which was unchanged from the acquisition date value.
