The Company reviews goodwill for impairment during the fourth quarter of each annual reporting period, and whenever events and circumstances indicate that the carrying values may not be recoverable. In the fourth quarter of 2014, the recoverability of all goodwill was evaluated by estimating future discounted cash flows. The Company recorded a noncash charge for the impairment of goodwill in the amount of $36.6 million on both a pre-tax and after-tax basis. The charge included $11.4 million of earthmoving/construction goodwill related to the acquisition of Titan Australia; $9.6 million of agricultural goodwill related to the acquisition of the Latin America farm tire business; and $15.6 million of goodwill related to the acquisition of Voltyre-Prom.
