[1] *The 2014 acquisition relates to the Company's 2014 purchase of Gustav Wahler GmbH u. Co. KG and its general partner. In the fourth quarter of 2014, a measurement period adjustment of $42.1 million was made to increase the fair value of the warranty liability at the acquisition date, see Note 7 "Product Warranty" to the Company's Annual Report on Form 10-K for the year ended December 31, 2014 for additional details. In the second quarter of 2015, the Company settled a significant warranty claim associated with a product issue that pre-dated the Company's acquisition of Gustav Wahler GmbH u. Co. KG. Including the impact of the reversal of a corresponding receivable, this settlement had an immaterial impact on the Condensed Consolidated Balance Sheet at September 30, 2015 and Condensed Consolidated Statements of Operations for the nine months ended September 30, 2015.
