The case was assigned to Judge Leonard P. Stark. GN sought injunctive relief, total damages in an unspecified amount, plus attorneys fees and costs, as well as unspecified legal and equitable relief. GN generally alleged that the Companys alleged exclusive dealing arrangements with certain distributors stifled competition in the relevant market.

The Company filed a motion for attorneys fees in November 2017, and that motion was denied by the Court in January 2018. The Company also filed a motion for certain recoverable costs, and the parties stipulated to an amount of approximately $0.2 million which GN paid the Company. If the jury verdict were to be appealed and later overturned on appeal, the Company would have to repay that amount to GN. On February 12, 2018, GN filed a notice of intent to appeal both the denial of the new trial motion and the Courts July 2016 spoliation order. The appellate court heard argument on the matter on December 11, 2018 and its decision is pending.

Polycom and the Company cooperated fully with these agencies regarding these matters. In December, 2018, the DOJ issued a declination to prosecute the matter. Polycom also agreed to settle the matter with the SEC and DOJ. The Company was reimbursed for the entire settlement amount as well as additional legal fees and expenses through funds retained in escrow under the Stock Purchase Agreement between the Company, Polycom and Triangle Private Holdings II, LLP. On September 13, 2018, Mr. Phil Shin filed on behalf of himself and others similarly situated, a purported Class Action Complaint in the United States District Court of the Northern District of California alleging violations of various federal and state consumer protection laws in addition to unfair competition and fraud claims in connection with the Companys BackBeat FIT headphones.

On January 23, 2018, Fullview, Inc. filed a complaint in the United States District Court of the Northern District of California against Polycom, Inc. alleging infringement of two patents and thereafter filed a similar complaint in connection with the same patents in Canada. Polycom thereafter filed an inter partes reexamination of the patents which is currently on appeal.

In addition to the specific matters discussed above, the Company is involved in various legal proceedings arising in the normal course of conducting business. Where applicable, in relation to the matters described above, the Company has accrued an amount that reflects the aggregate liability deemed probable and estimable, but this amount is not material to the Company's financial condition, results of operations, or cash flows. The Company is not able to estimate an amount or range of any reasonably possible loss, including in excess of any amount accrued, because of the preliminary nature of many of these proceedings, the difficulty in ascertaining the applicable facts relating to many of these proceedings, the variable treatment of claims made in many of these proceedings, and the difficulty of predicting the settlement value of many of these proceedings. However, based upon the Company's historical experience, the resolution of these proceedings is not expected to have a material effect on the Company's financial condition, results of operations or cash flows. The Company may incur substantial legal fees, which are expensed as incurred, in defending against these legal proceedings.
