Cost of Sales The Tokyo District Court and, on appeal in 2017, the Tokyo High Court have upheld the Japan customs authorities' customs assessments related to the importation of several of the Company's products into Japan.

24. Cost of Sales

The Tokyo District Court and, on appeal in 2017, the Tokyo High Court have upheld the Japan customs authorities' customs assessments related to the importation of several of the Company's products into Japan. We have appealed the High Court's decision to the Japan Supreme Court.

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.
