The Company leases manufacturing, warehouse and office space in the United States, China, Hong Kong, Spain and Ireland under non-cancelable operating leases that expire in 2021, 2022, 2022, 2023 and 2026, respectively.

The Company has, in the ordinary course of business, agreed to defend and indemnify certain customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks or trade secrets.

As permitted under Delaware law, the Company indemnifies its officers, directors and employees for certain events or occurrences that happen by reason of their relationship with or position held at the Company.

As of June 30, 2019 and December 31, 2018, the Company had not experienced any losses related to these indemnification obligations and no material claims were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible, and no related liabilities were recorded in its condensed consolidated financial statements.

On May 29, 2019 and July 3, 2019, two putative class action lawsuits were filed in the Massachusetts Superior Court against the Company and certain of its directors and officers, among others, alleging claims under the Securities Act of 1933, as amended, on behalf of a putative class of purchasers of the Company’s common stock in and/or traceable to the Company’s IPO. Plaintiffs base their claims on allegations that the defendants made material misrepresentations and omissions in documents that the Company issued in connection with its IPO. Plaintiffs seek compensatory damages, costs and expenses, including counsel and expert fees, rescission or a rescissory measure of damages, and equitable and injunctive relief. No amounts have been accrued for this matter in the quarter ended June 30, 2019 as the Company does not believe the likelihood of a material loss is probable. Although the ultimate outcome of this matter cannot be predicted with certainty, the resolution of this matter could have a material impact on the Company’s results of operations in the period in which the matter in resolved.
