1. Organization and Summary of significant accounting policies

Organization and nature of operations

MRV Communications, Inc. ("MRV" or the "Company"), a Delaware corporation, is a global supplier of communications solutions to telecommunications service providers, data center operators, enterprises and governments throughout the world. MRV’s technologies, platforms and expertise enable our customers to overcome the challenge of orchestrating the ever-increasing need for capacity while improving service delivery and lowering network costs for critical applications such as high-capacity business services, mobile backhaul and data center connectivity. MRV markets and sells its products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators. Until the third quarter of 2015, MRV conducted its business along two principal segments: the Network Equipment segment and the Network Integration segment. MRV's Network Equipment segment designs, manufactures, sells and services equipment used by commercial customers, governments, and telecommunications service providers. Products include packet switching, optical transport, infrastructure management and service provisioning software. The Network Integration segment, which primarily operated in Italy and provided network system design, integration and distribution services that includes products manufactured by third-party vendors, was sold in December 2015.

On December 3, 2015, the Company completed the sale of all of its shares of its wholly owned subsidiary, Tecnonet S.p.A.("Tecnonet"), pursuant to a shares purchase agreement, dated as of August 10, 2015 (the "Purchase Agreement") with Maticmind S.p.A, a company incorporated under the laws of Italy. Tecnonet was the last business unit in our Network Integration segment. On February 19, 2016, the Company received a payment of €4.3 million (approximately $4.8 million) representing the post-closing purchase price adjustment pursuant to the Purchase Agreement.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of MRV and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated.

The condensed consolidated unaudited financial statements included herein have been prepared by MRV pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information included in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2016, (this “Form 10-Q”) should be read in conjunction with the Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, (the “2015 Form 10-K”) filed with the SEC.

In the opinion of MRV's management, the unaudited interim financial information contained herein includes all normal recurring adjustments, necessary to present fairly the financial position of MRV as of June 30, 2016, and the results of its operations and comprehensive loss, and cash flows for the three and six months endedJune 30, 2016 and 2015. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the full year or any future periods.

Reclassification

Prior Period Reclassifications. On December 3, 2015, the Company completed the sale of Tecnonet. The results of operations for Tecnonet have been reclassified and presented as discontinued operations in this Form 10-Q for all periods presented. Cash flows from discontinued operations are presented separately from the cash flows from continuing operations in the accompanying Statement of Cash Flows. (See Note 15, Discontinued Operations)

Recently Issued Accounting Standards

We consider the applicability and impact of all Accounting Standards Updates (“ASUs”). The ASUs not listed below were assessed and determined by management to be either not applicable or are expected to have minimal impact on our consolidated financial position and/or results of operations.

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," ("ASU 2014-09"). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. ASU 2014-09 was originally effective for interim and annual reporting periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date, which defers the effective date to annual reporting periods beginning after December 15, 2017. Early application is permitted after December 15, 2016. Management is currently evaluating the potential impact that adopting ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. Management anticipates concluding its evaluation by December 31, 2016 and plans to adopt ASU 2014-09 on January 1, 2018.

In August 2014, the FASB issued ASU No. 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern" ("ASU 2014-15"). ASU 2014-15 provides guidance on management’s responsibility in evaluating whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2014-15 will have on its consolidated financial statements and footnote disclosures.

In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory" (“ASU 2015-11”). ASU 2015-11 simplifies the guidance on the subsequent measurement if inventory, excluding inventory measured using the last-in, first out of the retail inventory method. Under the new standard, inventory should be at the lower of cost and net realizable value. ASU 2015-11 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-11 will have on its consolidated financial statements and footnote disclosures.

In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes" ("ASU 2015-17"). The amendments in ASU 2015-17 simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current. ASU 2015-17 will become effective for the Company for fiscal years beginning after December 15, 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-17 will have on its consolidated financial statements and footnote disclosures.

In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). The amendments in ASU 2016-02 require companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations generated by contracts longer than a year. ASU 2016-02 will become effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The guidance is required to be applied using the modified retrospective transition approach. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-02 will have on its consolidated financial statements and footnote disclosures.

In March 2016, the FASB issued ASU No. 2016-09, "Stock Compensation (Topic 718): Improvements to employee Share-Based Payment Accounting" ("ASU 2016-09"). The amendments in ASU 2016-09 simplify the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 will become effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-09 will have on its consolidated financial statements and footnote disclosures.

2. Cash and Cash Equivalents and Restricted Time Deposits

MRV accounts for highly liquid investments with an original maturity of 90 days or less as cash equivalents. Investments with maturities of less than one year are considered short-term and are included on the balance sheet in restricted time deposits. MRV maintains cash balances and investments in qualified financial institutions, and at various times such amounts are in excess of federally insured limits. As of June 30, 2016 and December 31, 2015, the Company's U.S. entities held $20.9 million and $21.6 million in cash and cash equivalents. The remaining $3.9 million and $4.6 million, respectively, were held by the Company's foreign subsidiaries in foreign bank deposit accounts.

Restricted time deposits represent investments that are restricted as to withdrawal or use and from time to time may include certificates of deposit. Restricted time deposits generally secure standby letters of credit, bank lines of credit or bank loans. When investments in restricted time deposits are directly related to an underlying bank loan and the restricted funds will be used to repay the loans, the investment and the subsequent release of the restricted time deposit are treated as investing activities in the Company's Consolidated Statements of Cash Flows. The other investments in and releases of restricted time deposits are included in investing activities because the funds are invested in certificates of deposit. As of June 30, 2016 and December 31, 2015, the Company held $5.2 million of restricted time deposits; $5.0 million of which represents a certificate of deposit with a highly rated financial institution and matures in September 2016.

3. Fair Value Measurement

MRV's financial instruments, including cash and cash equivalents, restricted time deposits, accounts receivable, other receivables and accounts payable are carried at cost, which approximates their fair value. The fair values of accounts receivable, other receivables and accounts payable approximate their carrying amounts due to their short-term nature.

The Company follows a framework for measuring fair value using a three-level hierarchy that prioritizes the use of observable inputs. The fair value hierarchy is divided into three levels based on the source of inputs as follows: Level 1 - Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - Valuations for which all significant inputs are observable, either directly or indirectly, other than level 1 inputs for similar instruments; Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. Under this framework, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. Management has not elected the fair value option for non-financial assets and liabilities.

As of June 30, 2016 and December 31, 2015, the Company had cash equivalents consisting of money market funds of $0 and $1.8 million, respectively that were classified as Level 1 investments and were quoted at market price. Cash equivalents included in the condensed consolidated balance sheets are as follows (in thousands):

	Cost		Fair Value
June 30, 2016	$	—	$	—
December 31, 2015	$	1,807	$	1,807

4. Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality financial institutions and accounts receivable due from customers.

Management evaluates the collectability of accounts receivable based on a combination of factors. If management becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount that management reasonably believes to be collectable from the customer. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future. Accounts receivable are charged off at the point they are considered uncollectible.

The following table summarizes the changes in the allowance for doubtful accounts during the six months endedJune 30, 2016(in thousands):

Balance at beginning of period	$	1,060
(Reversed) to expense	(17		)
Write-offs, net of amounts recovered	(60		)
Foreign currency translation adjustment	5
Balance at end of period	$	988

5. Inventories

Inventories are stated at the lower of cost or market and consist of materials, labor and overhead. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis.

Inventories, net of reserves, consisted of the following at June 30, 2016 and December 31, 2015 (in thousands):

	June 30, 2016		December 31, 2015
Raw materials	$	2,923	$	3,132
Work-in process	1,075		839
Finished goods	4,409		6,255
Total	$	8,407	$	10,226

6. Intangible Assets

Intangible assets, net of amortization, consisted of intellectual property and totaled $1.0 million and $1.2 million as of June 30, 2016 and December 31, 2015, respectively. Amortization expense of intangible assets were approximately $122,000 and $90,000 for the six months ended June 30, 2016 and 2015, respectively. The terms of the some of these license agreements provide for use of the licensed software into perpetuity while others are definite. The Company amortizes the cost of the license agreements over the estimated useful life, which can range between three to five years. As of June 30, 2016, intangible assets not yet placed into service totaled approximately $0.4 million.

The following table illustrates the estimated future amortization expense of intangible assets as of June 30, 2016 (in thousands):

Fiscal Year Ending December 31,	Estimated Amortization Expense
2016 - remainder of the year	$	164
2017	280
2018	214
2019	214
2020	117
Thereafter	42
Total	$	1,031

7. Product Warranty

As of June 30, 2016, and December 31, 2015, MRV's product warranty liability recorded in accrued liabilities were $0.5 million and $0.6 million, respectively. MRV accrues for warranty costs as part of cost of sales based on associated material product costs, technical support labor costs and associated overhead. The products sold are generally covered by a warranty for periods of 90 days to three years.

The following table summarizes the activity related to the product warranty liability during the six months endedJune 30, 2016 (in thousands):

Balance at beginning of the period	$	593
(Reversed) to expense	(52		)
Accruals for product warranties	(17		)
Balance at end of the period	$	524

8. Net Loss Per Share

Basic net loss per share is computed using the weighted average number of shares of common stock outstanding, including restricted shares which, although they are legally outstanding and have voting rights, are subject to vesting and are treated as common stock equivalents in calculating basic net loss per share. Diluted net loss per share is computed using the weighted average number of shares of common stock outstanding and dilutive potential shares of common stock from stock options and warrants outstanding during the period. Diluted shares outstanding include the dilutive effect of in-the-money options, which is calculated based on the average share price for each period using the treasury stock method.

Employee share options, non-vested shares and similar equity instruments granted by MRV are treated as potential shares of common stock outstanding in computing diluted net income per share. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service not yet recognized, and the amount of income tax benefits that would be realized and recorded in additional paid-in capital if the deduction for the award would reduce income taxes payable are assumed to be used to repurchase shares.

The following table sets forth the computation of net loss per common share – basic and diluted (in thousands, except per share amounts):

	Three months ended						Six months ended
	June 30						June 30
	2016			2015			2016			2015
Numerator:
Net loss	$	(2,023	)	$	(281	)	$	(5,919	)	$	(1,349	)
Denominator
Basic weighted average common shares outstanding	7,092			6,988			7,042			7,059
Effect of dilutive securities	—			—			—			—
Diluted weighted average common shares outstanding	7,092			6,988			7,042			7,059
Net loss per common share
Basic	$	(0.29	)	$	(0.04	)	$	(0.84	)	$	(0.19	)
Diluted	$	(0.29	)	$	(0.04	)	$	(0.84	)	$	(0.19	)

Outstanding stock options to purchase 460,692 and 387,286 shares of common stock were excluded from the computation of dilutive loss per shares for the three months ended June 30, 2016 and 2015, respectively, as they were anti-dilutive. Outstanding stock options to purchase 419,990 and 366,812 shares were excluded from the computation of dilutive loss per shares for the six months ended June 30, 2016 and 2015, respectively, as they were anti-dilutive. Treasury shares are excluded from the number of shares outstanding.

9. Share-Based Compensation

MRV records share-based compensation expense at fair value. The following table summarizes the impact on MRV's results of operations of recording share-based compensation for the three and six months endedJune 30, 2016 and 2015 (in thousands):

	Three months ended				Six months ended
	June 30,				June 30,
	2016		2015		2016		2015
Cost of goods sold	$	28	$	25	$	70	$	55
Product development and engineering	63		44		139		93
Selling, general and administrative	259		167		488		294
Total share-based compensation expense (1)	$	350	$	236	$	697	$	442

(1) Income tax benefits realized from stock option exercises and similar awards were immaterial in all periods.

During the three and six months ended June 30, 2016, the Company granted 240,039 stock options with a related fair value of $4.86 per option and 88,869 restricted shares with a related fair value $10.95 per share. During the three and six months ended June 30, 2015, the Company granted 197,848 stock options with a related fair value of $4.16 per option and 71,872 restricted shares with a related fair value of $9.63 per share. No stock options or restricted shares were granted during the three months ended March 31, 2016 and 2015. As of June 30, 2016, the total unrecognized share-based compensation balance for unvested options, net of expected forfeitures, was $2.7 million and is expected to be amortized over a weighted-average period of 2.3 years.

Valuation Assumptions

MRV uses the Black-Scholes option pricing model to estimate the fair value of stock option awards or related modifications. The Black-Scholes model requires the use of subjective and complex assumptions, including the option's expected life and the underlying stock price volatility. MRV bases volatility on the Company's historical quoted prices and peer company data.

Six months ended June 30,	2016		2015
Risk-free interest rate	1.4	%	1.7	%
Dividend yield (1)	—		—
Volatility	46	%	43	%
Expected life (in years)	5.9		5.9

(1) As the Company does not pay a dividend on a regular basis, and dividends paid in the past have been special in nature, a dividend rate of zero was used.

10. Geographic Information

Following the completion of the sale of the Tecnonet business unit on December 3, 2015, MRV now has only one reportable segment: Network Equipment.

The Network Equipment segment designs, manufactures, sells and services equipment used by commercial customers, governments and telecommunications service providers. Products include packet switching, optical transport, infrastructure management and service provisioning software.

11. Indemnification Obligations

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. Most of the indemnification obligations have expired, however any indemnification obligations related to intellectual property extend until the third anniversary of the closing, while indemnification related to employee benefits, environmental liabilities and taxes extend until their applicable statute of limitations has run plus 90 days, and indemnification obligations are not time limited for title and ownership representations. These indemnification obligations are subject to a $1.0 million deductible and a $20.0 million cap, and we have purchased an insurance policy to protect against such obligations.

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. MRV 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.

Our agreements for the sale of certain business; CES in March 2012, Alcadon and Interdata in October 2012, and Tecnonet in December 2015, include customary indemnification obligations running to the respective buyers.

In connection with the sale of CES, MRV agreed to indemnify the buyer for the representations and warranties made in the sale and purchase agreement and purchased an insurance policy to protect against any claims of indemnification related to the representations and warranties.

In the normal course of business to facilitate sales of its products, MRV indemnifies other parties, including customers, lessors and parties to other transactions with us, with respect to certain matters. The Company has agreed to hold the other parties harmless against losses arising from a breach of representation or covenants, for intellectual property infringement, or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim.

In addition, the Company has indemnification obligations to its current and former officers, directors, employees and agents, as set forth in the Company's bylaws.

We cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these obligations. Over the last decade, the Company has not incurred any significant expense as a result of obligations of this type that were not otherwise covered by our insurance policies. Accordingly, the Company has not accrued any amounts for such indemnification obligations. However, there can be no assurances that expenses will not be incurred under these indemnification provisions in the future.

We have agreements whereby our officers and directors are indemnified for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we retain directors and officers insurance that reduces our exposure and enables us to recover portions of amounts paid. As a result of our insurance coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, no liabilities have been recorded for these agreements as of June 30, 2016 and December 31, 2015.

12. 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. The outcome of any such matters is currently not determinable. In addition, we were party to the litigation set forth below.

Nhan T. 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 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 resolution of such outstanding matters will not have a material adverse effect on our business, operating results and financial condition.

13. Share Repurchase

On March 15, 2016, the Company's Board of Directors approved a repurchase of shares of the Company's common stock in an amount up to $10.0 million under a stock repurchase program that expires on March 10, 2017. Through June 30, 2016, the Company repurchased 188,905 shares at a total cost of approximately $1.9 million, excluding commissions, under this stock repurchase program. As of June 30, 2016, the Company had remaining authority to repurchase shares up to an additional $8.1 million, excluding commissions, under this stock repurchase program prior to its expiration. Through August 2, 2016, the Company repurchased a total of 198,822 shares at a total cost of approximately $2.0 million, excluding commissions, under this stock repurchase program, leaving remaining authority to repurchase shares up to an additional $8.0 million, excluding commissions, under this stock repurchase program prior to its expiration.

14. Income Taxes

The following table provides details of income taxes for the three and six months ended June 30, 2016 and 2015 (in thousands, except percentages):

	Three months ended						Six months ended
	June 30,						June 30,
	2016			2015			2016			2015
Loss before provision for income taxes	$	(1,987	)	$	(1,048	)	$	(5,822	)	$	(2,298	)
Provision for income taxes	36			77			97			127
Effective tax rate	(2		)%	(7		)%	(2		)%	(6		)%

The effective tax rate fluctuates based on the amount of pre-tax income or loss generated in the various jurisdictions where we conduct operations and pay income tax. The income tax expense is primarily due to state minimum income taxes that do not benefit from our state net operating loss carryforwards and to income tax in foreign jurisdictions without net operating loss carryforwards.

As of December 31, 2015, MRV had federal, state and foreign net operating loss ("NOL") carryforwards available of $182.5 million, $97.1 million and $97.4 million, respectively. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carryforwards existing at that time could be limited. As of June 30, 2016, the federal, state and foreign NOLs had a full valuation allowance.

NOL Rights Plan

On January 26, 2016, in an effort to protect the Company from potential adverse consequences arising from an ownership change under the Internal Revenue Code, including a significant reduction in the annual utilization of the Company’s net operating loss carryforwards, built-in losses and the impairment or loss of the NOLs and built-in losses prior to their use, the Company's Board of Directors approved the adoption of the Rights Agreement with American Stock Transfer & Trust Company, LLC, ("Rights Plan"). Pursuant to the Rights Plan, the Company declared a dividend distribution of one preferred stock purchase right (each a “Right” and collectively, the "Rights") for each outstanding share of the Company’s common stock to stockholders of record as of the close of business on February 10, 2016 (the Record Date"). Except in certain circumstances set forth in the Rights Plan, each Right entitles the holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, $0.01 par value, of the Company (“Preferred Stock”) at a price of $68.64, subject to adjustment. The NOL Rights Plan was ratified by the Company's stockholders on June 15, 2016, at the Company's annual meeting of stockholders.

The Rights initially trade together with the common stock and are not exercisable. Subject to certain exceptions specified in the Rights Plan, the Rights will separate from the common stock and become exercisable following the earlier to of (i) the tenth calendar day after a public announcement or filing that a person or group has become an “Acquiring Person,” which is defined as a person who has acquired, or obtained the right to acquire, beneficial ownership of 4.99% or more of the common stock then outstanding, subject to certain exceptions, or (ii) the tenth calendar day (or such later date as may be determined by the Board of Directors) after any person or group commences a tender or exchange offer, the consummation of which would result in a person or group becoming an Acquiring Person. If a person or group becomes an Acquiring Person, each Right will entitle its holders (other than such Acquiring Person) to purchase one share at a price of $68.64, subject to adjustment. At any time after a person becomes an Acquiring Person, the Board of Directors may exchange all or part of the outstanding Rights (other than those held by an Acquiring Person) for shares of common stock at an exchange rate of one share of common stock for each Right. The Company will promptly give public notice of any exchange (although failure to give notice will not affect the validity of the exchange).

The Rights will expire upon certain events described in the Rights Plan, including the time at which the Rights are redeemed in accordance with the Agreement, the time at which the Rights are exchanged in accordance with the Agreement, or the time at which the Board Directors determines that the NOLs are fully utilized or no longer available under Section 382 of the Code. However, in no event will the Rights Plan expire later than the close of business on January 26, 2019. Until the close of business on the tenth calendar day after the day a public announcement or a filing is made indicating that a person or group has become an Acquiring Person, the Company may in its sole and absolute discretion amend the Rights or the Rights Plan without the approval of any holders of the Rights or shares of common stock in any manner, including without limitation, amendments that increase or decrease the purchase price or redemption price or accelerate or extend the final expiration date or the period in which the Rights may be redeemed. The Company may also amend the Rights Plan after the close of business on the tenth calendar day after the day such public announcement or filing is made to cure ambiguities, to correct defective or inconsistent provisions, to shorten or lengthen time periods under the Rights Plan or in any other manner that does not adversely affect the interests of holders of the Rights. No amendment of the Rights Plan may extend its expiration date.

15. Discontinued Operations

On December 3, 2015, the Company completed the sale of all of its shares of Tecnonet. On February 19, 2016, the Company received a payment of €4.3 million (approximately $4.8 million) representing the post-closing purchase price adjustment pursuant to the Purchase Agreement. The Company included the $4.8 million receivable representing the post-closing purchase price adjustment on its consolidated balance sheet within other current assets as of December 31, 2015. Prior to its disposition, Tecnonet was the last remaining business unit in our Network Integration segment. The historical financial results of Tecnonet, prior to its sale, have been reclassified as discontinued operations for all periods presented. The Company reported net income of $0.8 million and $1.1 million from discontinued operations, net of income tax expense, for the three and six months ended June 30, 2015, respectively, related to Tecnonet.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the Condensed Consolidated Financial Statements and Notes thereto included elsewhere in this Form10-Q, and Items 6, 7 and 8 of our2015Form10-K. The discussion in this Form10-Q contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, and may qualify for the safe harbor provided for in Section21E of the Exchange Act. We generally identify forward-looking statements as statements other than statements of historical fact and by use of such terms as “anticipate,”“appear,”“believe,”“contemplate,”“could,” “estimate,” “expect,”“intend,”“may,” “should,” “plan,”“project,”“target,” “foresee,” “goal,” “likely,” “will,” and “would,” or similar statements.

Forward-looking statements involve known and unknown risks and uncertainties that could cause actual results to differ materially from those projected. In addition, the statements in this Form10-Q may involve certain risks, uncertainties and assumptions, the likelihood of which are difficult to assess and may not occur, including risks that each of its business segments may not make the expected progress in its respective market, or that management's long-term strategy may not achieve the expected results. Other risks and uncertainties relate to delayed lead times in receiving components and delayed delivery times to customers due to short-term capacity constraints, potential changes in relationships with MRV's customers and suppliers and their financial condition, MRV's success in developing, introducing and shipping product enhancements and new products, competition in our market segments, market acceptance of new products and our ability to succeed in entering new markets, continued market acceptance of existing products and continued success in selling the products of other companies, product price discounts and general pricing pressure in certain of our markets, the timing and amount of significant orders from customers, obsolete inventory or product returns, warranty and other claims on products, the continued ability of MRV to protect its intellectual property rights and avoid onerous licensing fees, changes in product mix, maturing product life cycles, implementation of operating cost structures that align with revenue growth, political instability in areas of the world in which MRV operates or sells its products and services, currency fluctuations, changes in accounting rules, general economic conditions, as well as changes in such conditions specific to our market segments, maintenance of our inventory and production backlog, supply constraints directly or indirectly caused by natural disasters, litigation, including but not limited to patent infringement claims and litigation related to MRV's historical stock option granting practices.

In light of the risks and uncertainties inherent whenever matters or events expected to occur or not occur in the future are discussed, there can be no assurance that the forward-looking information contained in this Form10-Q will in fact transpire or prove to be accurate. All subsequent written and oral forward-looking statements attributable to the Company or persons acting on our behalf are expressly qualified in their entirety by this introduction. In light of the risks and uncertainties in all such projected operational matters, the inclusion of forward-looking statements in this Form10-Q should not be regarded as a representation by the Company or any other person that the objectives or plans of the Company will be achieved or that any of the Company's operating expectations will be realized. Revenue and results of operations are difficult to forecast and could differ materially from those projected in the forward-looking statements contained in this Form10-Q for the reasons detailed in Item 1A “Risk Factors” of Part I on the Company's 2015 Form 10-K and as set forth in item 1A of Part II of this Form 10-Q. Readers should not place undue reliance on forward-looking statements, which reflect management's view only as of the date of this Form10-Q. The Company undertakes no obligation to amend this Form10-Q or revise publicly these forward-looking statements (other than pursuant to requirements imposed on registrants pursuant to Item 1A under PartII of Form10-Q) to reflect subsequent events or circumstances. Readers should also carefully review the risk factors described in other documents the Company files from time to time with the SEC and the cautionary statements contained in our press releases when we provide forward-looking information.

Overview

At MRV, we design, manufacture, sell and service equipment used by telecommunications service providers, data center operators, enterprises and governments throughout the world. Our technologies, platforms and expertise enable our customers to overcome the challenge of orchestrating the ever-increasing need for capacity while improving service delivery and lowering network costs for critical applications such as high-capacity business services, mobile backhaul and data center connectivity. Products include packet switching, optical transport, infrastructure management and service provisioning software.

17

Until the third quarter of 2015, we operated our business along two principal segments: Network Equipment and Network Integration. Our Network Integration segment, which consisted of Tecnonet as its sole business unit, operated primarily in Italy, servicing Tier One service providers, regional carriers, large enterprises and government institutions. On December 3, 2015, the Company completed the sale of all of its shares of Tecnonet.

The sale of Tecnonet is reported as discontinued operations requiring retrospective restatement of prior periods to classify the results of operations for Tecnonet as discontinued operations in this Form 10-Q for all periods presented. Cash flows from discontinued operations are presented separately from the cash flows from continuing operations in the accompanying Statement of Cash Flows. (See Note 15, Discontinued Operations)

Our business involves reliance on foreign-based offices. Several of our divisions, outside subcontractors and suppliers are located in foreign countries including; Argentina, Australia, Canada, Denmark, Germany, Israel, Italy, Netherlands, Philippines, Poland, Russia, Taiwan, Thailand and the United Kingdom. For the six months ended June 30, 2016, and 2015, external revenues from foreign subsidiaries accounted for 22%, and 23%, respectively, of our total revenue. The majority of our foreign sales are to customers located in the Asia Pacific region, with remaining foreign sales primarily to customers in Europe and the Americas.

As of June 30, 2016, the Company had $24.8 million in cash and cash equivalents and $5.2 million in restricted time deposits.

On March 15, 2016, the Company's Board of Directors approved a repurchase of shares of the Company's common stock in an amount up to $10.0 million under a stock repurchase program that expires on March 10, 2017. Through June 30, 2016, the Company repurchased 188,905 shares at a total cost of approximately $1.9 million, excluding commissions, under this stock repurchase program. As of June 30, 2016, the Company had remaining authority to repurchase shares up to an additional $8.1 million, excluding commissions, under this stock repurchase program prior to its expiration. Through August 2, 2016, the Company repurchased a total of 198,822 shares at a total cost of approximately $2.0 million, excluding commissions, under this stock repurchase program, leaving remaining authority to repurchase shares up to an additional $8.0 million, excluding commissions, under this stock repurchase program prior to its expiration.

Critical Accounting Policies

Management's Discussion and Analysis of the Company's financial condition and results of operations are based upon the condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).

The preparation of these financial statements requires management to make estimates, assumptions and judgments that can affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management believes that the estimates, assumptions and judgments involved in the accounting policies described below have the greatest potential impact on our financial statements and considers these to be our critical accounting policies. Because of the uncertainty inherent in these matters, actual results could differ from the estimates we use in applying the critical accounting policies. Certain of these critical accounting policies affect working capital account balances, including the policies for revenue recognition, allowance for doubtful accounts, inventory reserves and income taxes. These policies require that we make estimates in the preparation of our financial statements as of a given date.

Within the context of these critical accounting policies, we are not currently aware of any reasonably likely events or circumstances that would result in materially different amounts being reported.

Revenue Recognition.    Our major revenue-generating products consist of packet switching, optical transport, infrastructure management and service provisioning software. We recognize product revenue, net of sales discounts, returns and allowances, when persuasive evidence of an arrangement exists, delivery has occurred and all significant contractual obligations have been satisfied, the fee is fixed or determinable and collection is considered reasonably assured. Products are generally shipped "FOB shipping point," with no right of return and revenue is recognized upon shipment. If revenue is to be recognized upon delivery, such delivery date is tracked through information provided by the third party shipping company we use to deliver the product to the customer. Sales of services and system support are deferred and recognized ratably over the contract period. Sales to end customers with contingencies, such as rights of return, rotation rights, conditional acceptance provisions and price protection, are infrequent and insignificant and are deferred until the contingencies have been satisfied or the contingent period has lapsed. For sales to distributors, we generally recognize revenue when product is sold to the distributor rather than when the product is sold by the distributor to the end user. In certain circumstances, distributors have limited rights of return, including stock rotation rights, and/or are entitled to price protection, where a rebate credit may be provided to the customer if we lower our price on products held in the distributor's inventory. We estimate and establish allowances for expected future product returns and credits. We record a reduction in revenue for estimated future product returns and future credits to be issued to the customer in the period in which revenue is recognized, and for future credits to be issued in relation to price protection at the time we make changes to our distributor price book. We monitor product returns and potential price adjustments on an ongoing basis and estimate future returns and credits based on historical sales returns, analysis of credit memo data, and other factors known at the time of revenue recognition.

We generally warrant our products against defects in materials and workmanship for 90 days to three year periods. The estimated costs of warranty obligations and sales returns and other allowances are recognized at the time of revenue recognition based on contract terms and prior claims experience.

Accounting for Multiple-Element Arrangements entered into prior to January 1, 2011. Arrangements with customers may include multiple deliverables involving combinations of equipment, services and software. In accordance with ASC 605-25 Multiple-Element Arrangements, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element is met. Fair value for each element is established based on the sales price charged when the same element is sold separately. If multiple element arrangements include software or software-related elements, we apply the provisions of ASC 985-605 Software to the software and software-related elements, or to the entire arrangement if the software is essential to the functionality of the non-software elements.

Accounting for Multiple-Element Arrangements entered into after January 1, 2011. We allocate arrangement consideration at the inception of the arrangement to all deliverables using the relative selling price method. The selling price we use for each deliverable is based on (a) vendor-specific objective evidence if available; (b) third-party evidence if vendor-specific objective evidence is not available; or (c) estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. We allocate discounts in the arrangement proportionally on the basis of the fair value of each deliverable.

Allowance for Doubtful Accounts. We make ongoing estimates relating to the collectability of our accounts receivable and maintain a reserve for estimated losses resulting from the inability of customers to meet their financial obligations to us. In determining the amount of the reserve, we consider our historical level of credit losses and make judgments about the creditworthiness of significant customers based on ongoing credit evaluations. Actual future losses from uncollectible accounts may differ from our estimates because we cannot precisely predict future changes in the financial stability of our customers. If the financial condition of our customers deteriorates, resulting in their inability to make payments, a larger reserve may be required. In the event we determine that a change in the allowance is appropriate, we would record a credit or a charge to selling, general and administrative expense in the period in which we make such a determination.

Concentration of Credit Risk.    Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents placed with financial institutions and accounts receivable due from customers. We perform ongoing credit evaluations of our customers and maintain reserves for potential credit losses.

19

Inventory.    We make ongoing estimates relating to the net realizable value of inventories, based upon our assumptions about future demand and market conditions. If we estimate that the net realizable value of our inventory is less than the cost of the inventory recorded on our books, we record an adjustment to the cost basis equal to the difference between the cost of the inventory and the estimated net realizable market value. This adjustment is recorded as a charge to cost of goods sold, and includes estimates for excess quantities and obsolete inventory. If changes in market conditions result in reductions in the estimated net realizable value of our inventory below previous estimates, we would make further adjustments in the period in which we make such a determination and record a charge to cost of goods sold. At the time of recording the adjustment, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration of, or increase in, that newly established cost basis.

Intangible Assets. We make judgments about the recoverability of intangible assets with finite lives whenever events or changes in circumstances indicate that impairment may exist. Recoverability of intangible assets with finite lives is measured by comparing the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. Our ongoing consideration of all the factors described previously could result in additional impairment charges in the future, which could adversely affect our net income.

Income Taxes. As part of the process of preparing our annual financial statements, we estimate the income taxes in each of the jurisdictions in which we operate based on the estimated annual effective tax rate by jurisdiction. This process involves estimating the current income tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for income tax and accounting purposes. These differences result in deferred income tax assets and liabilities, which are included in our Consolidated Balance Sheets. We assess the likelihood that our deferred income tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense within the income tax provision in the Condensed Consolidated Statements of Operations.

We utilize significant management judgment to determine the provision for income taxes, deferred income tax assets and liabilities, including uncertain tax positions and any valuation allowance recorded against net deferred income tax assets. Management periodically evaluates the deferred income tax assets as to whether it is likely that the deferred income tax assets will be realized. We establish a valuation allowance on the deferred income tax asset at the time we determine the asset is not likely to be realized. If we later determine that it is more-likely-than-not that a deferred tax asset will be realized, we release the valuation allowance and record a credit within the Condensed Consolidated Statements of Operations.

Share-Based Compensation.    We determine the fair value of stock options using the Black-Scholes valuation model. The assumptions used in calculating the fair value of share-based payment awards represent our best estimates. Our estimates may be impacted by certain variables including stock price volatility, employee stock option exercise behaviors, additional stock option grants, estimates of forfeitures and the related income tax impact. (See Note 9 “Share-Based Compensation” to the Financial Statements in Part 1, Item 1, of this Form 10-Q for further discussion.)

Revenue

Revenue decreased $2.9 million, or 12%, for the three months ended June 30, 2016 compared to the three months ended June 30, 2015, primarily due to a $2.8 million, or 13%, decrease in product revenue. The decrease in product revenue was primarily driven by decreased revenues in the United States, Europe and the Asia Pacific region due to reduced sales of legacy infrastructure management products and due to fewer large scale network projects, partially offset by an increase in sales to one of our larger run-rate customers. Conversely, we experienced improvement in the Americas, other than the United States, as we saw an increase in demand from Tier 1 and Tier 2 customers.

The following table summarizes revenue by geographic region (in thousands):

Three months ended June 30:	2016		2015		$ change			% change
Revenue:
United States	$	11,916	$	13,613	$	(1,697	)	(12	)%
Americas (Excluding the U.S.)	2,665		1,857		808			44	%
Europe	4,251		5,299		(1,048		)	(20	)%

Total revenue	$	21,584	$	24,519	$	(2,935	)	(12	)%

Gross Profit

The Company's cost of revenue consists of materials, compensation expense including non-cash stock-based compensation expense, depreciation expense and other manufacturing overhead costs, expenses associated with excess and obsolete inventories and product warranty costs. Historically, our cost of revenue as a percentage of revenue, has fluctuated significantly due to customer, product and sales channel mix, manufacturing yields, sales volumes and inventory and specific product warranty charges.

22

Gross profit decreased $1.9 million, or 16%, for the three months ended June 30, 2016, compared to the three months ended June 30, 2015, principally due to a $2.8 million, or 13%, decrease in product revenue. The combined gross profit margin for product and service revenues decreased 2.1 percentage points to 46.7% for the three months ended June 30, 2016, compared to 48.8% for the three months ended June 30, 2015. The gross profit margin for product revenues decreased 1 percentage point to 44.9% for the three months ended June 30, 2016, compared to 45.9% for the three months ended June 30, 2015, while the gross profit margin for service revenues decreased 11.3 percentage points to 58.0% for the three months ended June 30, 2016, compared to 69.3% for the three months ended June 30, 2015. The 1 percentage point decline in product gross profit margin was primarily a result of the mix of product sold and the geographic region the products were sold into. In addition, actions to improve operations and consolidate our contract manufacturing burdened the current quarter with an additional $0.3 million in expenses. The associated costs are considered non-recurring and we expect the efficiencies gained by these actions to generate ongoing financial benefits once fully implemented. The reduction in service revenue gross profit margin was primarily attributable to approximately $0.1 million of increased labor expense that was directly related to improvement efforts related to customer support and maintenance to enhance our customer experience. Additionally we increased our reserve for potentially excess and obsolete inventory by approximately $0.1 million in the quarter.

Operating Expenses

Operating expenses were $12.1 million, or 56.2% of revenue, for the three months ended June 30, 2016, compared to $12.7 million, or 51.8% of revenue, for the three months ended June 30, 2015. The $0.6 million, or 4% decrease in operating expenses for the three months ended June 30, 2016, compared to the three months ended June 30, 2015, were primarily driven by $0.3 million decrease in general and administrative expenses related to lower accounting and legal fees, in addition to a $0.2 million decrease in materials costs and other overhead related to product development and engineering and a $0.3 million decrease in labor expense for selling and general and administrative charges related to decreased headcount. These decreases were partially offset by a $0.2 million increase in general and administrative expenses related to increased share-based compensation expense and other overhead charges for the three months ended June 30, 2016, compared to the three months ended June 30, 2015.

Operating Loss

The Company reported operating loss of $2.1 million for the three months ended June 30, 2016 compared to an operating loss of $0.7 million for three months ended June 30, 2015. The $1.3 million decline in operating results was primarily the result of $1.9 million, or 16%, decrease in gross profit, offset by the $0.6 million, or 4% decrease in operating expenses. Our operating margin declined to (10)% for the three months ended June 30, 2016 compared to (3)% operating margin for the three months ended June 30, 2015. Operating loss included share-based compensation expense of $0.4 million and $0.2 million for the three months ended June 30, 2016 and 2015, respectively.

Provision for Income Taxes

The provision for income taxes for the three months ended June 30, 2016 and 2015, was approximately $36,000 and $77,000, respectively, and was computed based on an estimated annual effective tax rate for the Company in each of the various tax jurisdictions we operate. Our income tax provision fluctuates based on the amount of pre-tax income or loss generated in the various jurisdictions where we conduct operations and pay income tax.

Tax Loss Carryforwards

As of December 31, 2015, MRV had federal, state and foreign net operating loss ("NOL") carryforwards available of $182.5 million, $97.1 million and $97.4 million, respectively. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carryforwards existing at that time could be limited. As of June 30, 2016, the US federal and state NOLs had a full valuation allowance.

23

Discontinued Operations

On December 3, 2015, the Company completed the sale of all of its shares of Tecnonet. On February 19, 2016, the Company received a payment of €4.3 million (approximately $4.8 million) representing the post-closing purchase price adjustment pursuant to the Purchase Agreement. The Company included the $4.8 million receivable representing the post-closing purchase price adjustment on its consolidated balance sheet within other current assets as of December 31, 2015. Prior to its disposition, Tecnonet was the last remaining business unit in our Network Integration segment. The historical financial results of Tecnonet, prior to its sale have been reclassified as discontinued operations for all periods presented. The Company reported net income of $0.8 million from discontinued operations, net of income tax expense for the three months ended June 30, 2015, related to Tecnonet.

Revenue

Revenue decreased $6.2 million, or 13%, for the six months ended June 30, 2016 compared to the six months ended June 30, 2015, primarily due to a $6.3 million, or 15%, decrease in product revenue. The decrease in product revenue was driven by decreased revenues in all geographic regions, led by the United States, Europe and the Asia Pacific region and lastly the Americas, all primarily due to reduced sales of legacy infrastructure management products and fewer network expansion projects, particularly in the United States. Geographically, the $2.9 million decrease in revenues generated in the United States was mainly attributable to decreased order volume over the same period in the prior year from regional service providers for project related expansions. The $2.1 million decrease in revenues generated in Europe was a result of a decrease in channel partner order volume. The $0.6 million and $0.7 million decline in revenues generated in Asia Pacific and Americas, respectively, was primarily the result of decreased shippable order volume from some of our larger Australian and South American customers. Revenues for our infrastructure management products decreased $2.6 million, optical components sold with our systems decreased $2.0 million, Carrier Ethernet products decreased $1.2 million, optical transport products decreased $0.5 million during the six months ended June 30, 2016 compared to six months ended June 30, 2015.

Gross Profit

Gross profit decreased $3.6 million, or 15%, for the six months ended June 30, 2016, compared to the six months ended June 30, 2015, principally due to a $6.3 million, or 15%, decrease in product revenue. The combined gross profit margin for product and service revenues decreased 1.2 percentage points to 49.1% for the six months ended June 30, 2016, compared to 50.3% for the six months ended June 30, 2015. The gross profit margin for product revenues increased marginally at 0.3 percentage points to 48.4% for the six months ended June 30, 2016, compared to 48.1% for the six months ended June 30, 2015, while the gross profit margin for service revenues decreased 12.8 percentage points to 53.2% for the six months ended June 30, 2016, compared to 66.0% for the six months ended June 30, 2015. The marginal increase in product gross profit margin was primarily a result of the mix of products sold. The reduction in service revenue gross profit margin was primarily attributable to a $0.3 million increase in labor expense that was directly related to improvement efforts related to customer support and maintenance to enhance our customer experience, a charge of approximately $0.3 million for potentially excess and obsolete inventory, and a $0.1 million increase in material costs.

Operating Expenses

Operating expenses were $25.5 million, or 63.0% of revenue, for the six months ended June 30, 2016, compared to $25.6 million, or 54.7% of revenue, for the six months ended June 30, 2015. Operating expenses remained relatively consistent when compared to the prior year period. Product development and engineering labor expenses increased approximately $0.4 million primarily due to increased headcount offset by the $0.5 million decrease in selling, general and administrative labor expenses mainly due to decreased headcount and decreased sales commission expenses due primarily to lower product revenues. Operating expenses also improved due to lower accounting and legal fees.

Operating Loss

The Company reported operating loss of $5.6 million for the six months ended June 30, 2016 compared to an operating loss of $2.0 million for six months ended June 30, 2015. The $3.6 million decline in operating results was primarily the result of $6.2 million, or 13%, decrease in revenues. Our operating margin declined to (14)% for the six months ended June 30, 2016 compared to (4)% operating margin for the six months ended June 30, 2015. Operating loss included share-based compensation expense of $0.7 million and $0.4 million for the six months ended June 30, 2016 and 2015, respectively.

Provision for Income Taxes

The provision for income taxes for the six months ended June 30,2016 and 2015 was approximately $97,000 and $127,000, respectively and was computed based on an estimated annual effective tax rate for the Company in each of the various tax jurisdictions we operate. Our income tax provision fluctuates based on the amount of pre-tax income or loss generated in the various jurisdictions where we conduct operations and pay income tax.

Discontinued Operations

Prior to its disposition, Tecnonet was the last remaining business unit in our Network Integration segment. The historical financial results of Tecnonet, prior to its sale have been reclassified as discontinued operations for all periods presented. The Company reported net income of $1.1 million from discontinued operations, net of income tax expense for the six months ended June 30, 2015, related to Tecnonet.

25

Liquidity and Capital Resources

During the six months endedJune 30, 2016, the Company's cash decreased approximately $1.4 million to $24.8 million from $26.2 million. There were net cash inflows from working capital of approximately $0.3 million, including a$1.9 million decrease in inventory due to timing of shipments, a $0.4 million increase in other assets, offset by cash outflows of $1.1 million due to an increase in accounts and other receivable primarily due to timing of cash receipts, a $0.9 million decrease in deferred revenue due to timing of shipments, and a $0.1 million decrease in accounts payable and accrued liabilities due to timing of payments. Net cash provided by investing activities included $4.8 million in proceeds from the sale of the Tecnonet, offset by $0.4 million in purchases of property, plant and equipment. Net cash used in financing activities included $1.9 million in purchase of treasury shares.

We periodically review our capital position and consider returning capital to stockholders through special dividends or share repurchases when cash on hand exceeds our foreseeable cash needs. We also periodically review the capital needs of our business units. We plan to invest approximately $1.0 million over the next 12 months to upgrade our infrastructure and equipment needed to support the Company's growth objectives in the Carrier Ethernet and optical transport markets among others. We believe that cash on hand will be sufficient to satisfy current operating needs, capital expenditures and product development and engineering requirements for at least the next 12 months. We may seek to obtain debt financing if we believe it appropriate. We may limit our ability to use available NOLs and capital loss carryforwards if we seek financing through issuance of additional equity securities.

Working Capital

The following table summarizes our working capital position (in thousands):

	June 30, 2016		December 31, 2015
Current assets	$	56,296	$	63,273

Working capital	$	33,242	$	39,481
Current ratio(1)	2.4		2.7

(1) Determined by dividing total current assets by total current liabilities.

Off-Balance Sheet Arrangements

We do not have transactions, arrangements or other relationships with unconsolidated entities that are reasonably likely to affect our liquidity or capital resources. We have no special purpose or limited purpose entities that provided off-balance sheet financing, liquidity or market or credit risk support, engaged in leasing, hedging, research and development services, or other relationships that expose us to liability that is not reflected on the face of the financials.

Contractual Obligations

During the three months ended June 30, 2016, there were no material changes in our contractual obligations.

Internet Access to Our Financial Documents

We maintain a website at www.mrv.com. We make available, free of charge, either by direct access or hyperlink, our Annual Reports on Form10-K, Quarterly Reports on Form10-Q, Current Reports on Form8-K and amendments to those reports filed or furnished pursuant to Section13(a)or 15(d)of the Exchange Act as soon as reasonably practicable after such reports are electronically filed with, or furnished to, the SEC. Our reports filed with, or furnished to, the SEC are also available directly at the SEC's website at www.sec.gov.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may impact our Condensed Consolidated Financial Statements through adverse changes in financial market prices and rates and inflation. Our market risk exposure results primarily from fluctuations in foreign exchange and interest rates. We manage our exposure to these market risks through our regular operating and financing activities, and in certain instances, through the use of derivative financial instruments. These derivative instruments are used to manage risks of volatility in interest and foreign exchange rate movements on certain assets, liabilities or anticipated transactions and create a relationship in which gains or losses on derivative instruments are expected to counter-balance the losses or gains on the assets, liabilities or anticipated transactions exposed to such market risks. As of June 30, 2016, we did not have any such derivative financial instruments outstanding.

Interest Rates.    Our investments expose us to interest rate fluctuations. Our cash and short-term investments are subject to limited interest rate risk, and are primarily maintained in money market funds and bank deposits.

Foreign Exchange Rates.    We operate on an international basis with revenues and expenses transacted in currencies other than the U.S. dollar. Fluctuation in the value of these foreign currencies affects our results and will cause U.S. dollar translation of such currencies to vary from one period to another. We cannot predict the effect of exchange rate fluctuations upon future operating results. However, because we have revenues and expenses in each of these foreign currencies, the effect on our results of operations from currency fluctuations is reduced.

Certain assets and liabilities, including certain bank accounts, accounts receivables and accounts payables of some of our business units, exist in currencies other than the functional currency of the related business units and are sensitive to foreign currency exchange rate fluctuations. These currencies principally include the U.S. dollar, the Taiwan dollar, and the Israeli new shekel. When these transactions are settled in a currency other than the functional currency, we recognize a foreign currency transaction gain or loss.

When we translate the financial position or results of operations of subsidiaries with functional currencies other than the U.S. dollar, we recognize a foreign currency translation gain or loss as a component of other comprehensive income (loss). Changes in the relative values of non-U.S. currencies to the U.S. dollar affect our results. We conduct a significant portion of our business in foreign currencies, the Israeli new shekel and the Taiwan dollar. For the six months ended June 30, 2016 and 2015, 22% and 23% of external revenue, respectively, and 35% and 36% of operating expenses, respectively, were generated and incurred at foreign subsidiaries. For the six months ended June 30, 2016, the exchange rates for the Taiwan dollar weakened 5% against the U.S. dollar compared to the six months ended June 30, 2015, so revenue and expenses in these currencies translated into slightly fewer dollars than they would have in the prior period. For the six months ended June 30, 2016, the exchange rates for the Israeli new shekel strengthened 1% against the U.S. dollar compared to the six months ended June 30, 2015, so revenue and expenses in these currencies translated into slightly higher dollars than they would have in the prior period.

Fluctuations in currency exchange rates of foreign currencies have an impact on the U.S. dollar equivalent of such currencies included in cash and cash equivalents reported in our financial statements.

The following table summarizes cash and cash equivalents held in various currencies and translated into U.S. dollars (in thousands):

	June 30, 2016		December 31, 2015
U.S. dollars	$	22,058	$	23,461
Euros	109		171
Taiwan dollars	28		141

Macro-economic uncertainties.  We believe that the past few years of sustained softness in the global economy has affected our revenues and operating results. When economic uncertainties increase, our customers often take a more cautious approach in their capital expenditures, resulting in order delays, slowing deployments and lengthening sales cycles. This may lead to increased competition for projects and price pressures resulting in lower gross margins. Despite these economic uncertainties, we believe that our customers need to continue investing in their networks to meet the growth in consumer and enterprise use of high-bandwidth communications services. We believe in our longer term market opportunities, but we are uncertain how long the downturn in economic conditions will continue and how our customers will interpret and react to market conditions.

Item 4. Controls and Procedures

Under the supervision and with the participation of management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company has, pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined under Rule 13a-15(e) of the Exchange Act).

Based upon that evaluation the Company’s Chief Executive Officer and its Chief Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures are effective.

There was no change in our internal control over financial reporting during the three and six months ended June 30, 2016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

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. The outcome of any such matters is currently not determinable. In addition, we were party to the litigation set forth below.

Nhan T. 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 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.

28

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 resolution of such outstanding matters will not have a material adverse effect on our business, operating results and financial condition.

Item 1A. Risk Factors

There have been no material changes in the Company's risk factors that have been previously disclosed in Part I, Item 1A of the Company's 2015 Annual Report on Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Issuer Purchases of Equity Securities

On March 15, 2016, the Company's Board of Directors approved a repurchase of shares of the Company's common stock in an amount up to $10.0 million under a stock repurchase program that expires on March 10, 2017. Through June 30, 2016, the Company repurchased 188,905 shares at a total cost of approximately $1.9 million, excluding commission, under this stock repurchase program. As of June 30, 2016, the Company had remaining authority to repurchase shares up to an additional $8.1 million, excluding commission, under this stock repurchase program prior to its expiration.

Period	Total number of shares purchased	Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs	Maximum amount remaining for purchase under the repurchase plan

Organization and nature of operations

MRV Communications, Inc. ("MRV" or the "Company"), a Delaware corporation, is a global supplier of communications solutions to telecommunications service providers, data center operators, enterprises and governments throughout the world. MRV’s technologies, platforms and expertise enable our customers to overcome the challenge of orchestrating the ever-increasing need for capacity while improving service delivery and lowering network costs for critical applications such as high-capacity business services, mobile backhaul and data center connectivity. MRV markets and sells its products worldwide, through a variety of channels, which include a dedicated direct sales force, manufacturers' representatives, value-added-resellers, distributors and systems integrators. Until the third quarter of 2015, MRV conducted its business along two principal segments: the Network Equipment segment and the Network Integration segment. MRV's Network Equipment segment designs, manufactures, sells and services equipment used by commercial customers, governments, and telecommunications service providers. Products include packet switching, optical transport, infrastructure management and service provisioning software. The Network Integration segment, which primarily operated in Italy and provided network system design, integration and distribution services that includes products manufactured by third-party vendors, was sold in December 2015.

On December 3, 2015, the Company completed the sale of all of its shares of its wholly owned subsidiary, Tecnonet S.p.A.("Tecnonet"), pursuant to a shares purchase agreement, dated as of August 10, 2015 (the "Purchase Agreement") with Maticmind S.p.A, a company incorporated under the laws of Italy. Tecnonet was the last business unit in our Network Integration segment. On February 19, 2016, the Company received a payment of €4.3 million (approximately $4.8 million) representing the post-closing purchase price adjustment pursuant to the Purchase Agreement.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of MRV and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated.

The condensed consolidated unaudited financial statements included herein have been prepared by MRV pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information included in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2016, (this “Form 10-Q”) should be read in conjunction with the Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, (the “2015 Form 10-K”) filed with the SEC.

In the opinion of MRV's management, the unaudited interim financial information contained herein includes all normal recurring adjustments, necessary to present fairly the financial position of MRV as of June 30, 2016, and the results of its operations and comprehensive loss, and cash flows for the three and six months endedJune 30, 2016 and 2015. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the full year or any future periods.

Reclassification

Prior Period Reclassifications. On December 3, 2015, the Company completed the sale of Tecnonet. The results of operations for Tecnonet have been reclassified and presented as discontinued operations in this Form 10-Q for all periods presented. Cash flows from discontinued operations are presented separately from the cash flows from continuing operations in the accompanying Statement of Cash Flows. (See Note 15, Discontinued Operations)

Recently Issued Accounting Standards

We consider the applicability and impact of all Accounting Standards Updates (“ASUs”). The ASUs not listed below were assessed and determined by management to be either not applicable or are expected to have minimal impact on our consolidated financial position and/or results of operations.

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," ("ASU 2014-09"). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. ASU 2014-09 was originally effective for interim and annual reporting periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date, which defers the effective date to annual reporting periods beginning after December 15, 2017. Early application is permitted after December 15, 2016. Management is currently evaluating the potential impact that adopting ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. Management anticipates concluding its evaluation by December 31, 2016 and plans to adopt ASU 2014-09 on January 1, 2018.

In August 2014, the FASB issued ASU No. 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern" ("ASU 2014-15"). ASU 2014-15 provides guidance on management’s responsibility in evaluating whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2014-15 will have on its consolidated financial statements and footnote disclosures.

In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory" (“ASU 2015-11”). ASU 2015-11 simplifies the guidance on the subsequent measurement if inventory, excluding inventory measured using the last-in, first out of the retail inventory method. Under the new standard, inventory should be at the lower of cost and net realizable value. ASU 2015-11 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-11 will have on its consolidated financial statements and footnote disclosures.

In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes" ("ASU 2015-17"). The amendments in ASU 2015-17 simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current. ASU 2015-17 will become effective for the Company for fiscal years beginning after December 15, 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-17 will have on its consolidated financial statements and footnote disclosures.

In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). The amendments in ASU 2016-02 require companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations generated by contracts longer than a year. ASU 2016-02 will become effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The guidance is required to be applied using the modified retrospective transition approach. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-02 will have on its consolidated financial statements and footnote disclosures.

In March 2016, the FASB issued ASU No. 2016-09, "Stock Compensation (Topic 718): Improvements to employee Share-Based Payment Accounting" ("ASU 2016-09"). The amendments in ASU 2016-09 simplify the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 will become effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-09 will have on its consolidated financial statements and footnote disclosures.

Cash and Cash Equivalents [Abstract]

Cash and Cash Equivalents and Restricted Time Deposits

Cash and Cash Equivalents and Restricted Time Deposits

MRV accounts for highly liquid investments with an original maturity of 90 days or less as cash equivalents. Investments with maturities of less than one year are considered short-term and are included on the balance sheet in restricted time deposits. MRV maintains cash balances and investments in qualified financial institutions, and at various times such amounts are in excess of federally insured limits. As of June 30, 2016 and December 31, 2015, the Company's U.S. entities held $20.9 million and $21.6 million in cash and cash equivalents. The remaining $3.9 million and $4.6 million, respectively, were held by the Company's foreign subsidiaries in foreign bank deposit accounts.

Restricted time deposits represent investments that are restricted as to withdrawal or use and from time to time may include certificates of deposit. Restricted time deposits generally secure standby letters of credit, bank lines of credit or bank loans. When investments in restricted time deposits are directly related to an underlying bank loan and the restricted funds will be used to repay the loans, the investment and the subsequent release of the restricted time deposit are treated as investing activities in the Company's Consolidated Statements of Cash Flows. The other investments in and releases of restricted time deposits are included in investing activities because the funds are invested in certificates of deposit. As of June 30, 2016 and December 31, 2015, the Company held $5.2 million of restricted time deposits; $5.0 million of which represents a certificate of deposit with a highly rated financial institution and matures in September 2016.

Fair Value Measurement

Fair Value Measurement

MRV's financial instruments, including cash and cash equivalents, restricted time deposits, accounts receivable, other receivables and accounts payable are carried at cost, which approximates their fair value. The fair values of accounts receivable, other receivables and accounts payable approximate their carrying amounts due to their short-term nature.

The Company follows a framework for measuring fair value using a three-level hierarchy that prioritizes the use of observable inputs. The fair value hierarchy is divided into three levels based on the source of inputs as follows: Level 1 - Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - Valuations for which all significant inputs are observable, either directly or indirectly, other than level 1 inputs for similar instruments; Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. Under this framework, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. Management has not elected the fair value option for non-financial assets and liabilities.

As of June 30, 2016 and December 31, 2015, the Company had cash equivalents consisting of money market funds of $0 and $1.8 million, respectively that were classified as Level 1 investments and were quoted at market price. Cash equivalents included in the condensed consolidated balance sheets are as follows (in thousands):

Receivables [Abstract]

Credit Risk

Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality financial institutions and accounts receivable due from customers.

Management evaluates the collectability of accounts receivable based on a combination of factors. If management becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount that management reasonably believes to be collectable from the customer. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future. Accounts receivable are charged off at the point they are considered uncollectible.

The following table summarizes the changes in the allowance for doubtful accounts during the six months endedJune 30, 2016(in thousands):

Balance at beginning of period	$	1,060

Earnings Per Share [Abstract]

Net Loss Per Share

Net Loss Per Share

Basic net loss per share is computed using the weighted average number of shares of common stock outstanding, including restricted shares which, although they are legally outstanding and have voting rights, are subject to vesting and are treated as common stock equivalents in calculating basic net loss per share. Diluted net loss per share is computed using the weighted average number of shares of common stock outstanding and dilutive potential shares of common stock from stock options and warrants outstanding during the period. Diluted shares outstanding include the dilutive effect of in-the-money options, which is calculated based on the average share price for each period using the treasury stock method.

Employee share options, non-vested shares and similar equity instruments granted by MRV are treated as potential shares of common stock outstanding in computing diluted net income per share. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service not yet recognized, and the amount of income tax benefits that would be realized and recorded in additional paid-in capital if the deduction for the award would reduce income taxes payable are assumed to be used to repurchase shares.

The following table sets forth the computation of net loss per common share – basic and diluted (in thousands, except per share amounts):

	Three months ended						Six months ended
	June 30						June 30
	2016			2015			2016			2015

Outstanding stock options to purchase 460,692 and 387,286 shares of common stock were excluded from the computation of dilutive loss per shares for the three months ended June 30, 2016 and 2015, respectively, as they were anti-dilutive. Outstanding stock options to purchase 419,990 and 366,812 shares were excluded from the computation of dilutive loss per shares for the six months ended June 30, 2016 and 2015, respectively, as they were anti-dilutive.

During the three and six months ended June 30, 2016, the Company granted 240,039 stock options with a related fair value of $4.86 per option and 88,869 restricted shares with a related fair value $10.95 per share. During the three and six months ended June 30, 2015, the Company granted 197,848 stock options with a related fair value of $4.16 per option and 71,872 restricted shares with a related fair value of $9.63 per share. No stock options or restricted shares were granted during the three months ended March 31, 2016 and 2015. As of June 30, 2016, the total unrecognized share-based compensation balance for unvested options, net of expected forfeitures, was $2.7 million and is expected to be amortized over a weighted-average period of 2.3 years.

Valuation Assumptions

MRV uses the Black-Scholes option pricing model to estimate the fair value of stock option awards or related modifications. The Black-Scholes model requires the use of subjective and complex assumptions, including the option's expected life and the underlying stock price volatility. MRV bases volatility on the Company's historical quoted prices and peer company data.

Risk-free interest rate	1.4	%	1.7	%
Dividend yield (1)	—		—
Volatility	46	%	43	%

Indemnification Obligations

Indemnification Obligations

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. Most of the indemnification obligations have expired, however any indemnification obligations related to intellectual property extend until the third anniversary of the closing, while indemnification related to employee benefits, environmental liabilities and taxes extend until their applicable statute of limitations has run plus 90 days, and indemnification obligations are not time limited for title and ownership representations. These indemnification obligations are subject to a $1.0 million deductible and a $20.0 million cap, and we have purchased an insurance policy to protect against such obligations.

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. MRV 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.

Our agreements for the sale of certain business; CES in March 2012, Alcadon and Interdata in October 2012, and Tecnonet in December 2015, include customary indemnification obligations running to the respective buyers.

In connection with the sale of CES, MRV agreed to indemnify the buyer for the representations and warranties made in the sale and purchase agreement and purchased an insurance policy to protect against any claims of indemnification related to the representations and warranties.

In the normal course of business to facilitate sales of its products, MRV indemnifies other parties, including customers, lessors and parties to other transactions with us, with respect to certain matters. The Company has agreed to hold the other parties harmless against losses arising from a breach of representation or covenants, for intellectual property infringement, or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim.

In addition, the Company has indemnification obligations to its current and former officers, directors, employees and agents, as set forth in the Company's bylaws.

We cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these obligations. Over the last decade, the Company has not incurred any significant expense as a result of obligations of this type that were not otherwise covered by our insurance policies. Accordingly, the Company has not accrued any amounts for such indemnification obligations. However, there can be no assurances that expenses will not be incurred under these indemnification provisions in the future.

We have agreements whereby our officers and directors are indemnified for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we retain directors and officers insurance that reduces our exposure and enables us to recover portions of amounts paid. As a result of our insurance coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, no liabilities have been recorded for these agreements as of June 30, 2016 and December 31, 2015.

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. The outcome of any such matters is currently not determinable. In addition, we were party to the litigation set forth below.

Nhan T. 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 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 resolution of such outstanding matters will not have a material adverse effect on our business, operating results and financial condition.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The following table provides details of income taxes for the three and six months ended June 30, 2016 and 2015 (in thousands, except percentages):

	Three months ended						Six months ended
	June 30,						June 30,
	2016			2015			2016			2015
Loss before provision for income taxes	$	(1,987	)	$	(1,048	)	$	(5,822	)	$	(2,298	)
Provision for income taxes	36			77			97			127
Effective tax rate	(2		)%	(7		)%	(2		)%	(6		)%

The effective tax rate fluctuates based on the amount of pre-tax income or loss generated in the various jurisdictions where we conduct operations and pay income tax. The income tax expense is primarily due to state minimum income taxes that do not benefit from our state net operating loss carryforwards and to income tax in foreign jurisdictions without net operating loss carryforwards.

As of December 31, 2015, MRV had federal, state and foreign net operating loss ("NOL") carryforwards available of $182.5 million, $97.1 million and $97.4 million, respectively. Under the Internal Revenue Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change NOLs, capital loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in its equity ownership by value over a three-year period. We may experience an ownership change in the future as a result of subsequent shifts in our stock ownership. If we were to trigger an ownership change in the future, our ability to use any NOLs and capital loss carryforwards existing at that time could be limited. As of June 30, 2016, the federal, state and foreign NOLs had a full valuation allowance.

NOL Rights Plan

On January 26, 2016, in an effort to protect the Company from potential adverse consequences arising from an ownership change under the Internal Revenue Code, including a significant reduction in the annual utilization of the Company’s net operating loss carryforwards, built-in losses and the impairment or loss of the NOLs and built-in losses prior to their use, the Company's Board of Directors approved the adoption of the Rights Agreement with American Stock Transfer & Trust Company, LLC, ("Rights Plan"). Pursuant to the Rights Plan, the Company declared a dividend distribution of one preferred stock purchase right (each a “Right” and collectively, the "Rights") for each outstanding share of the Company’s common stock to stockholders of record as of the close of business on February 10, 2016 (the Record Date"). Except in certain circumstances set forth in the Rights Plan, each Right entitles the holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, $0.01 par value, of the Company (“Preferred Stock”) at a price of $68.64, subject to adjustment. The NOL Rights Plan was ratified by the Company's stockholders on June 15, 2016, at the Company's annual meeting of stockholders.

The Rights initially trade together with the common stock and are not exercisable. Subject to certain exceptions specified in the Rights Plan, the Rights will separate from the common stock and become exercisable following the earlier to of (i) the tenth calendar day after a public announcement or filing that a person or group has become an “Acquiring Person,” which is defined as a person who has acquired, or obtained the right to acquire, beneficial ownership of 4.99% or more of the common stock then outstanding, subject to certain exceptions, or (ii) the tenth calendar day (or such later date as may be determined by the Board of Directors) after any person or group commences a tender or exchange offer, the consummation of which would result in a person or group becoming an Acquiring Person. If a person or group becomes an Acquiring Person, each Right will entitle its holders (other than such Acquiring Person) to purchase one share at a price of $68.64, subject to adjustment. At any time after a person becomes an Acquiring Person, the Board of Directors may exchange all or part of the outstanding Rights (other than those held by an Acquiring Person) for shares of common stock at an exchange rate of one share of common stock for each Right. The Company will promptly give public notice of any exchange (although failure to give notice will not affect the validity of the exchange).

The Rights will expire upon certain events described in the Rights Plan, including the time at which the Rights are redeemed in accordance with the Agreement, the time at which the Rights are exchanged in accordance with the Agreement, or the time at which the Board Directors determines that the NOLs are fully utilized or no longer available under Section 382 of the Code. However, in no event will the Rights Plan expire later than the close of business on January 26, 2019. Until the close of business on the tenth calendar day after the day a public announcement or a filing is made indicating that a person or group has become an Acquiring Person, the Company may in its sole and absolute discretion amend the Rights or the Rights Plan without the approval of any holders of the Rights or shares of common stock in any manner, including without limitation, amendments that increase or decrease the purchase price or redemption price or accelerate or extend the final expiration date or the period in which the Rights may be redeemed. The Company may also amend the Rights Plan after the close of business on the tenth calendar day after the day such public announcement or filing is made to cure ambiguities, to correct defective or inconsistent provisions, to shorten or lengthen time periods under the Rights Plan or in any other manner that does not adversely affect the interests of holders of the Rights. No amendment of the Rights Plan may extend its expiration date.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of MRV and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated.

The condensed consolidated unaudited financial statements included herein have been prepared by MRV pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information included in this Quarterly Report on Form 10-Q for the quarter ended June 30, 2016, (this “Form 10-Q”) should be read in conjunction with the Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, (the “2015 Form 10-K”) filed with the SEC.

In the opinion of MRV's management, the unaudited interim financial information contained herein includes all normal recurring adjustments, necessary to present fairly the financial position of MRV as of June 30, 2016, and the results of its operations and comprehensive loss, and cash flows for the three and six months endedJune 30, 2016 and 2015. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the full year or any future periods.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

We consider the applicability and impact of all Accounting Standards Updates (“ASUs”). The ASUs not listed below were assessed and determined by management to be either not applicable or are expected to have minimal impact on our consolidated financial position and/or results of operations.

In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," ("ASU 2014-09"). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. ASU 2014-09 was originally effective for interim and annual reporting periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date, which defers the effective date to annual reporting periods beginning after December 15, 2017. Early application is permitted after December 15, 2016. Management is currently evaluating the potential impact that adopting ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. Management anticipates concluding its evaluation by December 31, 2016 and plans to adopt ASU 2014-09 on January 1, 2018.

In August 2014, the FASB issued ASU No. 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern" ("ASU 2014-15"). ASU 2014-15 provides guidance on management’s responsibility in evaluating whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2014-15 will have on its consolidated financial statements and footnote disclosures.

In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory" (“ASU 2015-11”). ASU 2015-11 simplifies the guidance on the subsequent measurement if inventory, excluding inventory measured using the last-in, first out of the retail inventory method. Under the new standard, inventory should be at the lower of cost and net realizable value. ASU 2015-11 will become effective for the Company in the first quarter of fiscal 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-11 will have on its consolidated financial statements and footnote disclosures.

In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes" ("ASU 2015-17"). The amendments in ASU 2015-17 simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current. ASU 2015-17 will become effective for the Company for fiscal years beginning after December 15, 2017 with early adoption permitted. Management is currently evaluating the potential impact that adopting ASU 2015-17 will have on its consolidated financial statements and footnote disclosures.

In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). The amendments in ASU 2016-02 require companies that lease assets to recognize on their balance sheets the assets and liabilities for the rights and obligations generated by contracts longer than a year. ASU 2016-02 will become effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The guidance is required to be applied using the modified retrospective transition approach. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-02 will have on its consolidated financial statements and footnote disclosures.

In March 2016, the FASB issued ASU No. 2016-09, "Stock Compensation (Topic 718): Improvements to employee Share-Based Payment Accounting" ("ASU 2016-09"). The amendments in ASU 2016-09 simplify the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 will become effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. Management is currently evaluating the potential impact that adopting ASU 2016-09 will have on its consolidated financial statements and footnote disclosures.

Allowance for Doubtful Accounts Policy

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents placed with high credit quality financial institutions and accounts receivable due from customers.

Management evaluates the collectability of accounts receivable based on a combination of factors. If management becomes aware of a customer's inability to meet its financial obligations after a sale has occurred, the Company records an allowance to reduce the net receivable to the amount that management reasonably believes to be collectable from the customer. If the financial conditions of MRV's customers were to deteriorate or if economic conditions worsen, additional allowances may be required in the future. Accounts receivable are charged off at the point they are considered uncollectible.

Schedule of valuation assumptions

MRV uses the Black-Scholes option pricing model to estimate the fair value of stock option awards or related modifications. The Black-Scholes model requires the use of subjective and complex assumptions, including the option's expected life and the underlying stock price volatility. MRV bases volatility on the Company's historical quoted prices and peer company data.
