COST OF SALES [Abstract] |
COST OF SALES | 15. COST OF SALES In April 2017, the Tokyo High Court issued a ruling on a dispute between the Company and the customs authorities in Japan. The High Court affirmed the Tokyo District Court’s February 2016 decision upholding previous customs assessments related to the importation of several of the Company’s products into Japan during 2010. The Company filed an appeal with the Japan Supreme Court in May 2017. The High Court’s April 2017 ruling applied only to imports that occurred during 2010, but in September 2017, the Tokyo High Court issued its ruling regarding imports that occurred in 2006-2009 and 2011, which are the other time periods in the dispute. For both of these time periods, the High Court affirmed the Tokyo District Court's decisions upholding previous customs assessments. In October 2017, the Company filed an appeal with the Japan Supreme Court regarding the Tokyo High Court’s September 2017 ruling. As previously disclosed, the Company already recorded a charge of $31.4 million to cost of sales in the first quarter of 2016, when the District Court issued its decision. This charge represents the full amount being disputed. It was a non-cash item because the Company was previously required to pay the assessments.
