We performed our annual indefinite-lived intangible assets impairment analysis as of April 1, 2018, which included an assessment of qualitative and quantitative factors to determine whether it is more likely than not that the fair values of the indefinite-lived intangible assets are less than the carrying amount. We concluded that the fair values of our indefinite-lived intangible assets exceeded carrying value and therefore step two of the assessment was not required.
