Subsequent Events	20. Subsequent Events Discontinued Operations On February 11, 2016, we announced our intention to sell the speaker and receiver product line within the MCE business segment. As a result, the Company expects to reclassify the assets, liabilities, and results of operations of the product line to discontinued operations in the first quarter of 2016. As no sale agreement has been agreed to with a buyer for this product line, proceeds from the sale are not currently estimable. During the year ended December 31, 2015, Knowles recorded pre-tax impairment charges of $191.5 million resulting from the carrying value of the speaker and receiver product line’s net assets being greater than the fair value.

The impairments were recorded within the Impairment of fixed and other assets and Impairment of intangible assets line items within the Consolidated Statements of Earnings.
