Based upon the results of our annual impairment analysis, the fair value of our Infrastructure Solutions and Commercial & Industrial segments exceeded the book value at September 30, 2017, and warranted no impairment. We evaluated goodwill attributable to our Residential segment qualitatively, and have concluded no impairment is indicated.
