Manufacturing Commitments

The Company subcontracts with manufacturing companies to manufacture its hardware products. The contract manufacturers procure components based on non-cancelable orders the Company places with them. If the Company cancels all or part of an order, the Company is liable to the contract manufacturers for the cost of the related components they purchased under such orders.

As of March 31, 2017 and December 31, 2016, the Company had manufacturing commitments with contract manufacturers for inventory totaling approximately $10.9 million and $9.5 million, respectively.

Contingencies

The Company may be subject to legal proceedings and litigation arising from time to time. The Company will record a liability when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. The Company expects to periodically evaluate developments in its legal matters that could affect the amount of liability that it has previously accrued, if any, and make adjustments as appropriate. The Company exercises significant judgment to determine both likelihood of there being, and the estimated amount of, a loss related to such matters, and the Company’s judgment may be incorrect. The Company cannot reasonably determine in advance the outcome of any litigation proceeding. Until the final resolution of any such matter for which the Company may be required to accrue, the Company may have an exposure to loss in excess of the amount the Company has accrued, and such excess amount could be significant.

The Company is currently engaged in the following separate litigations which allege that the Company’s products infringe certain patents.

•

Linex Technologies, or Linex, filed on March 19, 2013 a complaint in the U.S. District Court, Southern District of Florida, asserting that some or all of the Company’s products infringe U.S. Patents Nos. #6,493,377, or the ‘377 Patent, and #7,167,503, or the ’503 Patent. The Company filed an answer and counterclaims for declaratory judgment against Linex asserting that the Company’s products do not infringe the ‘377 and ‘503 Patents, and that the ‘377 and ‘503 Patents are, in any case, invalid and not enforceable. The Company separately filed with the U.S. Patent and Trademark Office, or the PTO, petitions to initiate reexamination of the ‘377 and ‘503 Patents, which the PTO granted. In the PTO reexaminations, all claims under the ‘377 and '503 Patents have been rejected and Linex has appealed the final rejections of the claims. This case is currently stayed pending the reexaminations.

Chrimar Systems, or Chrimar, filed in July 2015 a complaint in the U.S. District Court, Eastern District of Texas, asserting that certain of the Company’s products which utilize Power over Ethernet ("POE") functionality infringe United States Patent Nos. 8,155,012, or the '012 Patent, 8,902,760, or the '760 Patent, 8,942,107, or the '107 Patent and 9,019,838, or the '838 Patent. A jury trial was conducted in January 2017, following which the court entered an order finding non-infringement as to the Company's products under all patents in suit. The court subsequently entered a final judgment as to non-infringement under the patents in suit, which neither party challenged or appealed prior to the lapsing of the period for any such timely challenges or appeals. The Company separately filed with the PTO petitions to initiate reexamination of the '012 Patent and the '760 Patent, which petitions the PTO granted. The PTO has rejected all claims of the '012 Patent and is considering the Company's petition regarding the '760 Patent.

Mobile Telecommunications Technologies LLC, or Mobile, filed in May 2016 a complaint in the U.S. District Court, Eastern District of Texas, asserting that certain of the Company’s products which utilize MIMO systems or frequency structures and functionality infringe United States Patent Nos. 5,590,403, 5,659,891, and 5,915,210. The case was consolidated with several other cases involving the same patents and transferred to U.S. District Court, Delaware, for pretrial purposes.

The Company intends to defend these lawsuits vigorously, and is not able to predict or estimate any range of reasonably possible loss related to these lawsuits. If these matters have an adverse outcome, they may have a material impact on the Company’s financial position, results of operations or cash flows.
