Brammo is a privately held designer and developer of electric vehicles, which Polaris has invested in since 2011. The investment in Brammo is accounted for under the cost method. Brammo is in the early stages of designing, developing, and selling electric vehicle powertrains. As such, a risk exists that Brammo may not be able to secure sufficient financing to reach viability through cash flow from operations. In January 2015, Polaris acquired the electric motorcycle business from Brammo. Brammo will continue to be a designer and developer of electric vehicle powertrains. Polaris will impair or write off an investment and recognize a loss if and when events or circumstances indicate there is impairment in the investment that is other-than-temporary. When necessary, Polaris evaluates investments in nonmarketable securities for impairment, utilizing level 3 fair value inputs. During 2014 and 2013, Polaris recorded an immaterial impairment expense within other expense (income), net in the consolidated statements of income, and reduced the Brammo investment.
