Litigation

Due to the nature of the businesses in which the Company is engaged it is subject to certain risks. Such risks include, among others, risk of liability for personal injury or death to persons using products the Company promotes or commercializes. There can be no assurance that substantial claims or liabilities will not arise in the future due to the nature of the Company’s business activities and recent increases in litigation related to healthcare products.

The Company could also be held liable for errors and omissions of its employees in connection with the services it performs that are outside the scope of any indemnity or insurance policy. The Company could be materially adversely affected if it were required to pay damages or incur defense costs in connection with a claim that is outside the scope of an indemnification agreement; if the indemnity, although applicable, is not performed in accordance with its terms; or if the Company’s liability exceeds the amount of applicable insurance or indemnity.

As of December 31, 2018, the Company’s accrual for litigation and threatened litigation was not material to the consolidated financial statements.

Under the terms of the settlement agreement, the Company was obligated to make payments to the DOJ for the calendar years ended December 31, 2014 through 2017, up to a maximum of $3.0 million. Payments were due on March 31st following the calendar year in which the revenue milestones were achieved. The Company made payments totaling $0.5 million during the year ended December 31, 2017 related to fiscal 2016 and had accrued $0.5 million for its potential liability for fiscal 2017, the final year of the settlement agreement.
