[1] During 2015 and 2014, the Company reviewed the underlying cause of the decline in value of certain cost method investments, as well as the severity and the duration of the decline and determined that the decline was other-than-temporary. Impairment charges were recognized based upon the calculation of the investments' estimated fair value.
