Cost of Sales [Abstract] |
Cost of Sales | 23. Cost of Sales In February 2016, the Tokyo District Court issued its ruling on a dispute between the Company and the customs authorities in Japan. The District Court upheld previous customs assessments related to the importation of several of the Company's products into Japan. As a result of the District Court's decision, the Company recorded a charge of $31.4 million to cost of sales in the first quarter of 2016. This is a non-cash item because the Company was previously required to pay the assessments. This charge represents the full amount that was disputed, including assessments for the period of October 2006 through September 2009 in connection with post-importation audits, as well as the disputed portion of the Company's import duties from October 2009 to the date of the District Court's decision. The Company has appealed this decision to the Tokyo High Court.
