Legal Proceedings

In the normal course of business, the Company may become involved in legal proceedings. The Company will accrue a liability for legal proceedings when it is probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. At September 30, 2018 and December 31, 2017, the Company was not involved in any material legal proceedings.

Purchase Commitments

At September 30, 2018 and December 31, 2017, the Company had no outstanding firm purchase commitments.
