We performed our annual goodwill impairment analysis for 2015 in accordance with ASU No. 2011-08, Intangibles-Goodwill and Other: Testing Goodwill for Impairment. This analysis included an assessment of quantitative factors to determine whether it is more likely than not that the fair values of the reporting units are less than the carrying amounts. We assessed our goodwill by performing step one fair value calculations on a quantitative basis for each of our reporting units. We concluded that the fair values of our reporting units exceeded the carrying values and therefore step two of the assessment was not required. We concluded that goodwill had not been impaired based on the annual goodwill impairment analysis for 2015 and 2014.
