Litigation	Litigation We are subject to legal claims and litigation in the ordinary course of business, including but not limited to product liability, employment and intellectual property claims.

Vo, individually and on behalf of other aggrieved employees vs. the Company, Superior Court of California, County of Los Angeles. On June 27, 2013, the plaintiff in this matter filed a lawsuit against the Company alleging claims for failure to properly pay overtime or provide meal and rest breaks to its non-exempt employees in California, among other things. The complaint seeks an unspecified amount of damages and penalties under provisions of the Labor Code, including the Labor Code Private Attorneys General Act. The Company has filed an answer denying all allegations regarding the plaintiff’s claims and asserting various defenses. Management believes it has accrued adequate reserves for this matter and does not expect the matter to have a material adverse effect on its business or financial condition. However, depending on the actual outcome of this case, further provisions could be recorded in the future which may have a material adverse effect on the Company’s operating results. In connection with the sale by MRV of Source Photonics, Inc. (“SPI”) in October 2010, MRV agreed to indemnify the buyer against certain claims brought after the closing for prior-occurring events. The Company has received a notice from SPI, advising the Company of a tax audit for periods including tax returns filed prior to the acquisition of SPI by the buyer. Management believes that it has meritorious defenses to the extent a formal indemnification claim is asserted and has submitted the potential claim to its insurer. MRV intends to vigorously contest any claim; however, no formal legal proceeding has been commenced, and MRV can provide no assurance that such claim would not have a material adverse effect on its business, operating results or financial condition. From time to time, MRV receives notices from third parties alleging possible infringement of patents with respect to product features or manufacturing processes. Management believes such notices are common in the communications industry because of the large number of patents that have been filed on these subjects. The Company's policy is to discuss these notices with the parties in an effort to demonstrate that MRV's products and/or processes do not violate any patents. Management does not believe that any of these matters will result in a material adverse outcome. MRV and its subsidiaries have from time to time been named as a defendant in other lawsuits involving matters that management considers routine to the nature of its business. Management is of the opinion that the ultimate outstanding resolution of such outstanding matters will not have a material adverse effect on our business, operating results and financial condition.
