Notes to Unaudited Condensed Consolidated Financial Statements


(1)	Organization and Summary of Significant Accounting Policies


(a)	Description of Business

DASAN Zhone Solutions, Inc. (formerly known as Zhone Technologies, Inc. and referred to, collectively with its subsidiaries, as "DZS" or the "Company") is a global provider of network access solutions and communications equipment for service provider and enterprise networks. The Company provides a wide array of reliable, cost-effective networking technologies, including broadband access, Ethernet switching, mobile backhaul, Passive Optical LAN and software-defined networks, to a diverse customer base that includes more than 1,000 customers in more than 50 countries worldwide.

DZS was incorporated under the laws of the state of Delaware in June 1999. On September 9, 2016, the Company acquired Dasan Network Solutions, Inc. ("DNS") through the merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company (the "Merger"). At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by DASAN Networks, Inc. ("DNI") were canceled and converted into the right to receive shares of the Company's common stock in an amount equal to 58% of the issued and outstanding shares of the Company's common stock immediately following the Merger. In connection with the Merger, the Company changed its name from Zhone Technologies, Inc. to DASAN Zhone Solutions, Inc. For periods through September 8, 2016, Zhone Technologies, Inc. is referred to as "Legacy Zhone." The Company’s common stock continues to be traded on the Nasdaq Capital Market, and the Company’s ticker symbol was changed from "ZHNE" to "DZSI" effective September 12, 2016. The Company is headquartered in Oakland, California.


(b)	Going Concern

The accompanying condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP"), assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Accordingly, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability of the Company to continue as a going concern.

The Company has incurred significant losses to date and losses from operations may continue. The Company incurred net losses of $3.5 million and $15.3 million for the three months ended March 31, 2017 and for the year ended December 31, 2016, respectively. The Company had accumulated deficit of $23.7 million and working capital of $55.2 million as of March 31, 2017. As of March 31, 2017, the Company had approximately $17.3 million in cash and cash equivalents, which included $8.4 million in cash balances held by the Company's Korean subsidiary, and $31.5 million in aggregate principal amount of outstanding borrowings under the Company's credit facility with Wells Fargo Bank (the "WFB Facility"), the Company's short-term debt obligations and the Company's loans from DNI. In addition, the Company had $5.7 million in aggregate borrowing availability under its revolving credit facilities as of March 31, 2017. The Company had $6.2 million committed as security for letters of credit under these facilities as of March 31, 2017. Due to the amount of short-term debt obligations maturing within the next 12 months and the Company's recurring operating losses, the Company's cash resources may not be sufficient to settle these debt obligations. The Company's ability to continue as a “going concern” is dependent on many factors, including, among other things, its ability to comply with the covenants in its existing debt agreements, its ability to cure any defaults that occur under its debt agreements or to obtain waivers or forbearances with respect to any such defaults, and its ability to pay, retire, amend, replace or refinance its indebtedness as defaults occur or as interest and principal payments come due. Although the process of amending, replacing or refinancing the Company’s short-term debt obligations is ongoing and the Company is in active discussions with multiple parties, there is no guarantee that they will result in transactions that are sufficient to provide the Company with the required liquidity to remove the substantial doubt as to its ability to continue as a going concern. If the Company is unable to amend, replace or refinance its short-term debt obligations or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, the Company may experience material adverse impacts on its business, operating results and financial condition.

The Company has continued its focus on cost control and operating efficiency along with restrictions on discretionary spending, however in order to meet the Company's liquidity needs and finance its capital expenditures and working capital needs for its business, the Company may be required to sell assets, issue debt or

Table of Contents

equity securities, purchase credit insurance or borrow on potentially unfavorable terms. In addition, the Company may be required to reduce the scope of its planned product development, reduce sales and marketing efforts and reduce its operations in low margin regions, including reductions in headcount. Based on the Company's current plans and business conditions, the Company believes that its focused operating expense discipline along with its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for at least the next 12 months, however the factors discussed above raise substantial doubt about the Company's ability to continue as a going concern. The accompanying condensed consolidated financial statements do not include any adjustments that may result from the outcome of the uncertainties set forth above.


(c)	Risks and Uncertainties

As result of the Merger, DNI owned approximately 58% of the outstanding shares of the Company's common stock as of March 31, 2017. Thereafter, for so long as DNI and its affiliates hold shares of the Company's common stock representing at least a majority of the votes, DNI will be able to freely nominate and elect all the members of the Company's board of directors. The directors elected by DNI will have the authority to make decisions affecting the Company's capital structure, including the issuance of additional capital stock or options, the incurrence of additional indebtedness, the implementation of stock repurchase programs, and the declaration of dividends. The interests of DNI may not coincide with the interests of the Company's other stockholders or with holders of the Company's indebtedness. DNI’s ability to control all matters submitted to the Company's stockholders for approval limits the ability of other stockholders to influence corporate matters and, as a result, the Company may take actions that the Company's other stockholders or holders of our indebtedness do not view as beneficial. See Note 2, Note 9 and Note 11 to the consolidated financial statements for additional information.

As discussed above in Note 1(b), there is also substantial doubt about the Company's ability to continue as a going concern. The accompanying unaudited consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.


(d)	Correction of Errors

In this Quarterly Report on Form 10-Q, certain prior quarter financial information has been revised due to correction of certain errors. The Company identified errors related to the timing of revenue recognition in the consolidated financial statements for the quarter ended March 31, 2016. Correction of this error resulted in a decrease in total net revenue of $0.5 million, an increase in net loss of $0.3 million and an increase in basic and diluted net loss per share attributable to DZSI of $0.03 for the quarter ended March 31, 2016. The prior quarter financial information has also been revised for the classification of certain related party revenue, related party cost of revenue, and related royalty fees. This correction resulted in the Company reclassifying revenues of $4.8 million to related party revenues and costs of $4.0 million to related party cost of revenue for the quarter ended March 31, 2016. Finally, an understatement of the cash flows used in investing activities of $1.1 million was corrected in the statement of cashflows for the three months ended March 31, 2016. The overall impact of these errors on the Company's condensed consolidated financial position and results of operations is not material and as such, previously filed quarterly financial information contained in our proxy statement filed with the SEC on August 8, 2016 affected by the errors has not been amended.


(e)	Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

The condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. All intercompany transactions and balances have been eliminated in consolidation. The results of operations for the current interim period are not necessarily indicative of results to be expected for the current year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission.

As discussed more fully in Note 2, the Merger is treated as a reverse acquisition for accounting purposes, with DNS as the acquirer of the Company. As such, the consolidated financial results of the Company for the three months ended March 31, 2017 are compared to the financial results for DNS and its consolidated subsidiaries for

Table of Contents

the three months ended March 31, 2016. The balance sheet of the Company reflects the fair value of the assets and liabilities of Legacy Zhone as of the effective date of the Merger. Those assets include the fair value of acquired intangible assets and goodwill. Due to the foregoing, the Company’s financial results for the three months ended March 31, 2017 are not comparable to its financial results for the three months ended March 31, 2016.

Except as otherwise specifically noted herein, all references to the "Company" refer to (i) DNS and its consolidated subsidiaries for periods through September 8, 2016 and (ii) the Company and its consolidated subsidiaries for periods on or after September 9, 2016.


(f)	Reverse Stock Split

On February 28, 2017, the Company filed a Certificate of Amendment with the Delaware Secretary of State to amend the Company's Restated Certificate of Incorporation, which amendment effected a one-for-five reverse stock split of the Company's common stock and reduced the authorized shares of the Company's common stock from 180 million to 36 million. As a result of the reverse stock split, the number of shares of the Company’s common stock then issued and outstanding was reduced from approximately 81.9 million to approximately 16.4 million. References to shares of the Company's common stock, stock options (and associated exercise price) and restricted stock units in this Quarterly Report on Form 10-Q are provided on a post-reverse stock split basis.


(g)	Concentration of Risk

The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, Internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts. For the three months ended March 31, 2017, two customers represented 12% (related party) and 11% of net revenue, respectively. For the three months ended March 31, 2016, three customers represented 26% (a related-party) , 14% and 11% of net revenue, respectively.

As of March 31, 2017, two customers represented 18% and 16% (related party) of net accounts receivable, respectively. As of December 31, 2016, two customers represented 12% (related party) and 10% of net accounts receivable, respectively.

As of March 31, 2017 and December 31, 2016, receivables from customers in countries other than the United States represented 85% and 87%, respectively, of net accounts receivable.


(2)	Merger

On September 9, 2016, the Company acquired DNS through the Merger of a wholly owned subsidiary of the Company with and into DNS, with DNS surviving as a wholly owned subsidiary of the Company. The Merger combines leading technology platforms with a broadened customer base.

At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by DNI were canceled and converted into the right to receive shares of the Company's common stock in an amount equal to 58% of the issued and outstanding shares of the Company's common stock immediately following the Merger. Accordingly, at the effective time of the Merger, the Company issued 9,493,016 shares (post reverse stock split) of the Company’s common stock to DNI as consideration in the Merger, of which 949,302 shares (post reverse stock split) are being held in escrow as security for claims for indemnifiable losses in accordance with the merger agreement relating to the Merger. As a result, immediately following the effective time of the Merger, DNI held 58% of the outstanding shares of the Company's common stock and the holders of the Company's common stock immediately prior to the Merger retained, in the aggregate, 42% of the outstanding shares of the Company's common stock.

As described in Note 1(d), the Company accounted for the Merger as a reverse acquisition under the acquisition method of accounting in accordance with ASC 805, "Business Combination." Consequently, for the purpose of the purchase price allocation, DNS' assets and liabilities have been retained at their carrying values and Legacy Zhone's assets acquired, and liabilities assumed, by DNS (as the accounting acquirer in the Merger) have been recorded at their fair value measured as of September 9, 2016.

Table of Contents

The total purchase consideration in the Merger is based on the number of shares of Legacy Zhone common stock and Legacy Zhone stock options vested and outstanding immediately prior to the closing of the Merger, and was determined based on the closing price of $5.95 per share (post reverse stock split) of the Company's common stock on the September 9, 2016. The estimated total purchase consideration is calculated as follows (in thousands):



	Shares	Estimated Fair Value
Shares of Legacy Zhone stock as of September 8, 2016	6,874	$	40,902
Legacy Zhone stock options	198	540
Total Purchase Consideration		$	41,442

The following table summarizes the allocation of the fair value consideration transferred for the acquisition date (in thousands):



Cash and cash equivalents	$	7,013
Accounts receivable	18,510
Inventory	16,456
Prepaid expenses and other current assets	2,191
Property and equipment	4,339
Other assets	125
Identifiable intangible assets	10,479
Goodwill	3,284
Accounts payable	(11,021		)
Accrued and other liabilities	(7,089		)
Other long-term liabilities	(2,845		)
Total Indicated Fair Value of Assets	$	41,442

The goodwill was primarily attributed to people, geographic diversification and complementary products. The goodwill arising from the Merger is not tax deductible.

The Company considered the deferred tax liabilities caused by the Merger to be a source of income to support recoverability of acquired deferred tax assets, before considering the recoverability of the acquirer's existing deferred tax assets. Accordingly, the valuation allowance on the acquiree's deferred tax assets was reduced by the deferred tax liabilities caused by the Merger and accounted for as part of the purchase price allocation.

The following table presents the fair values of the acquired intangible assets at the effective date of the Merger (in thousands, except years):



	Useful life (in Years)	Fair Value
Developed technology	5	$	3,060
Customer relationships	10	5,240
Backlog	1	2,179
		$	10,479

The following unaudited pro forma condensed combined financial information for the three months ended March 31, 2016 gives effect to the Merger as if it had occurred at the beginning of 2015. The unaudited pro forma condensed combined financial information has been included for comparative purposes only and is not necessarily indicative of what the combined Company's financial position or results of operations might have been had the Merger been completed as of the date indicated.

(3) Fair Value Measurement

The Company utilizes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:



Level 1 –	Inputs are quoted prices in active markets for identical assets or liabilities.
Level 2 –	Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 –	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The following financial instruments are not measured at fair value on the Company’s consolidated balance sheet as of March 31, 2017 and December 31, 2016, but require disclosure of their fair values: cash and cash equivalents, short-term investments, accounts receivable, accounts payable and debt. The carrying values of financial instruments such as cash and cash equivalents, short-term investments, accounts receivable and accounts payable approximate their fair values based on their short-term nature. The carrying value of the Company's debt approximates their fair values based on the current rates available to the Company for debt of similar terms and maturities.


(4)	Inventories

Inventories as of March 31, 2017 and December 31, 2016 were as follows (in thousands):



	March 31, 2017		December 31, 2016
Raw materials	$	15,896	$	13,547
Work in process	4,339		3,705
Finished goods	15,678		13,780
Total inventories	$	35,913	$	31,032

Inventories provided as collateral for borrowings from Export-Import Bank of Korea amounted to $19.6 million as of March 31, 2017.


(5)	Property and Equipment

Property and equipment as of March 31, 2017 and December 31, 2016 were as follows (in thousands):



	March 31, 2017			December 31, 2016
Furniture and fixtures	$	21,919		$	20,040
Machinery and equipment	4,981			4,530
Leasehold improvements	3,406			3,573
Computers and software	425			411

	31,739			29,476
Less accumulated depreciation and amortization	(25,111		)	(22,922		)
Less government grants	(242		)	(266		)

The interest rate on the WFB Facility was 3.65% at March 31, 2017. The maturity date under the WFB Facility is March 31, 2019.

The Company’s obligations under the WFB Facility are secured by substantially all of its personal property assets and those of its subsidiaries that guarantee the WFB Facility, including their intellectual property. The WFB Facility contains certain financial covenants, and customary affirmative covenants and negative covenants. If the Company defaults under the WFB Facility due to a covenant breach or otherwise, WFB may be entitled to, among other things, require the immediate repayment of all outstanding amounts and sell the Company’s assets to satisfy the obligations under the WFB Facility.

(10)	Net Loss Per Share Attributable to DASAN Zhone Solutions, Inc.

Basic net loss per share attributable to DASAN Zhone Solutions, Inc. is computed by dividing the net loss attributable to DASAN Zhone Solutions, Inc. for the period by the weighted average number of shares of common stock outstanding during the period. The calculation of diluted net loss per share attributable to DASAN Zhone Solutions, Inc. gives effect to common stock equivalents; however, potential common equivalent shares are excluded if their effect is antidilutive. Potential common equivalent shares are composed of incremental shares of common equivalent shares issuable upon the exercise of stock options and the vesting of restricted stock units.

Basic net loss per share is the same as diluted net loss per share for the three months ended March 31, 2016 because DNS did not issue the potentially dilutive common stock. Basic net loss per share is the same as diluted net loss per share for the three months ended March 31, 2017 because the effects of stock options and unvested restricted stock units would have been anti-dilutive.

The Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on its consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.

(13)	Income Taxes

Income tax expense (benefit) for the three months ended March 31, 2017 and 2016, was $0.4 million and -$0.6 million, respectively on pre-tax losses of $3.1 million and $4.4 million, respectively. As of March 31, 2017, the income tax rate

Table of Contents

varied from the United States statutory income tax rate primarily due to valuation allowances in the United States and taxable income generated by the Company’s wholly-owned foreign subsidiaries.

The total amount of unrecognized tax benefits, including interest and penalties, at March 31, 2017 was not material. The amount of tax benefits that would impact the effective income tax rate, if recognized, is not expected to be material. There were no significant changes to unrecognized tax benefits during the quarters ended March 31, 2017 and 2016. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The open tax years for the major jurisdictions are as follows:



• Federal	2013 - 2016
• California and Canada	2012 - 2016
• Brazil	2011 - 2016
• Germany	2012 - 2016
• Japan	2011 - 2016
• Korea	2015 - 2016
• United Kingdom	2014 - 2016
• Vietnam	2016

However, due to the fact the Company had net operating losses and credits carried forward in most jurisdictions, certain items attributable to closed years are still subject to adjustment by the relevant taxing authority through an adjustment to tax attributes carried forward to open years.

The Company estimates that its foreign income will generally be subject to taxation in the United States on a current basis and that its foreign subsidiaries and representative offices will therefore not have any material untaxed earnings subject to deferred taxes. In addition, to the extent the Company is deemed to have sufficient connection to a particular taxing jurisdiction to enable that jurisdiction to tax the Company but the Company has not filed an income tax return in that jurisdiction for the year(s) at issue, the jurisdiction would typically be able to assert a tax liability for such years without limitation on the number of years it may examine.

The Company is not currently under examination for income taxes in any material jurisdiction.

Forward-Looking Statements

This report, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements regarding future events and our future results that are subject to the safe harbors created under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements are based on current expectations, estimates, forecasts, and projections about the industries in which we operate and the beliefs and assumptions of our management. We use words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “target,” “will,” “would,” variations of such words, and similar expressions to identify forward-looking statements. In addition, statements that refer to projections of earnings, revenue, costs or other financial items; anticipated growth and trends in our business or key markets; cost synergies, growth opportunities and other financial and operating benefits of the Merger; future growth and revenues from our products; our ability to refinance or repay our existing indebtedness prior to the applicable maturity date; future economic conditions and performance; anticipated performance of products or services; plans, objectives and strategies for future operations; and other characterizations of future events or circumstances, are forward-looking statements. Readers are cautioned that these forward-looking statements are only predictions and are subject to risks, uncertainties and assumptions that are difficult to predict, including those identified under the heading “Risk Factors” in Part II, Item 1A, elsewhere in this report and our other filings with the Securities and Exchange Commission (the SEC). Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Factors that might cause such a difference include, but are not limited to, our ability to realize the anticipated cost savings, synergies and other benefits of the Merger and any integration risks relating to the Merger, the ability to generate sufficient revenue to achieve or sustain profitability, the ability to raise additional capital to fund existing and future operations or to refinance or repay our existing indebtedness, defects or other performance problems in our products, any economic slowdown in the telecommunications industry that restricts the ability of our customers to purchase our products, commercial acceptance of our products, intense competition in the communications equipment market from large equipment companies as well as private companies with products that address the same networks needs as our products, higher than anticipated expenses that we may incur, any failure to comply with the periodic filing and other requirements of The Nasdaq Stock Market for continued listing, material weaknesses or other deficiencies in our internal control over financial reporting, the initiation of any civil litigation, regulatory proceedings, government enforcement actions or other adverse effects relating to the Audit Committee investigation or errors in the consolidated financial statements of Legacy Zhone and other factors identified elsewhere in this report and in our most recent reports on Forms 10-K, 10-Q and 8-K. We undertake no obligation to revise or update any forward-looking statements for any reason.

OVERVIEW

We are a global provider of network access solutions and communications equipment for service provider and enterprise networks. We research, develop, test, sell, manufacture and support communications equipment in five major areas: broadband access, Ethernet switching, mobile backhaul, passive optical LAN (POLAN) and software defined networks (SDN).

Table of Contents

As discussed under "Liquidity and Capital Resources" below, the maturing of short-term debt obligations and our recurring losses from operations raise substantial doubt on whether we will be able to continue as a going concern.

As of March 31, 2017, the total outstanding principal amount of our debt obligations was $31.5 million, consisting of the following:


•	$24.7 million in short-term debt obligations;


•	$1.8 million in short-term debt obligations to related parties; and


•	$5.0 million in long-term debt obligations to related parties.

Our ability to continue as a “going concern” is dependent on many factors, including, among other things, our ability to comply with the covenants in our existing debt agreements, our ability to cure any defaults that occur under our debt agreements or to obtain waivers or forbearances with respect to any such defaults, and our ability to pay, retire, amend, replace or refinance our indebtedness as defaults occur or as interest and principal payments come due.

Going forward, our key financial objectives include the following:


•	Increasing revenue while continuing to carefully control costs;


•	Continued investments in strategic research and product development activities that will provide the maximum potential return on investment; and


•	Minimizing consumption of our cash and cash equivalents.

Merger

On September 9, 2016, we acquired DNS through the merger of a wholly owned subsidiary of Zhone Technologies, Inc. with and into DNS, with DNS surviving as our wholly owned subsidiary (the Merger). In connection with the Merger, Zhone Technologies, Inc. changed its name to DASAN Zhone Solutions, Inc. Our common stock continues to be traded on the Nasdaq Capital Market, and our ticker symbol was changed from "ZHNE" to "DZSI" effective September 12, 2016.

At the effective time of the Merger, all issued and outstanding shares of capital stock of DNS held by its sole shareholder, DASAN Networks, Inc. (DNI), were canceled and converted into the right to receive shares of our common stock in an amount equal to 58% of the issued and outstanding shares of our common stock immediately following the Merger. Accordingly, at the effective time of the Merger, we issued 9,493,016 shares (post reverse stock split) of our common stock to DNI as consideration in the Merger, of which 949,302 shares (post reverse stock split) are being held in escrow as security for claims for indemnifiable losses in accordance with the merger agreement relating to the Merger. As a result, immediately following the effective time of the Merger, DNI held 58% of the outstanding shares of our common stock and the holders of our common stock immediately prior to the Merger retained, in the aggregate, 42% of the outstanding shares of our common stock. See Note 2 to the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report for additional information regarding the Merger.

ITEMS AFFECTING COMPARABILITY OF OUR FINANCIAL RESULTS

As discussed in Note 1(e) to the unaudited condensed consolidated financial statements set forth in Part I, Item 1 of this report, the Merger has been accounted for as a reverse acquisition under which DNS was considered the accounting acquirer of Legacy Zhone. As such, our financial results for the three months ended March 31, 2017 presented in this report are compared to the financial results of DNS and its consolidated subsidiaries for the three months ended March 31, 2016. Our balance sheet includes the fair value of the assets and liabilities of Legacy Zhone as of the effective date of the Merger. Those assets include the fair value of acquired intangible assets and goodwill. Due to the foregoing, our financial results for the three months ended March 31, 2017 are not comparable to our financial results for the three months ended March 31, 2016.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no material changes to our critical accounting policies and estimates from the information provided in Part II, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” included in our Annual Report on Form 10-K for the year ended December 31, 2016.

For the three months ended March 31, 2017, net revenue increased 106% or $26.8 million to $52.1 million from $25.3 million for the same period last year. For the three months ended March 31, 2017, product revenue increased 103% or $25.2 million to $49.7 million compared to the same period last year. The increase in product revenue for the three months ended March 31, 2017 was primarily related to the consummation of the Merger in September 2016 (which resulted in the inclusion of product revenue related to the Legacy Zhone business for the current year quarter).

Service revenue represents revenue from maintenance and other services associated with product shipments. For the three months ended March 31, 2017, service revenue increased 200% or $1.6 million to $2.4 million compared to the same period last year. The increase in service revenue for the three months ended March 31, 2017 was primarily related to the consummation of the Merger in September 2016 (which resulted in the inclusion of service revenue related to the Legacy Zhone business for the current year quarter), as well as an increase in sales of maintenance services.

International net revenue increased 69% or $15.8 million to $38.8 million for the three months ended March 31, 2017 from $23.0 million for the same period last year, and represented 74% of total net revenue compared with 91% during the same period of 2016. The increase in international net revenue for the three months ended March 31, 2017 was primarily related to the consummation of the Merger in September 2016 (which resulted in the inclusion of international net revenue related to the Legacy Zhone business for the current year quarter). The year-over-year decrease in international net revenue as a percentage of total net revenue reflects the inclusion of net revenue related to the Legacy Zhone business in North America in the current year period.

For the three months ended March 31, 2017, two customers represented 12% and 11% of net revenue, respectively. For the three months ended March 31, 2016, three customers represented 26% (a related-party), 14% and 11% of net revenue, respectively. We anticipate that our results of operations in any given period may depend to a large extent on sales to a small

Table of Contents

number of large accounts. As a result, our revenue for any quarter may be subject to significant volatility based upon changes in orders from one or a small number of key customers.

Cost of Revenue and Gross Margin

Total cost of revenue increased 66% or $13.6 million to $34.3 million for the three months ended March 31, 2017, compared to $20.7 million for the three months ended March 31, 2016. The increase in total cost of revenue for the three months ended March 31, 2017 was primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of cost of revenue related to the Legacy Zhone business for the current year quarter) as well as increased sales. Gross margin slightly increased due to improved manufacturing efficiencies and product mix for the three months ended March 31, 2017, compared to the three months ended March 31, 2016.

We expect that in the future our cost of revenue as a percentage of net revenue will vary depending on the mix and average selling prices of products sold. In addition, continued competitive and economic pressures could cause us to reduce our prices, adjust the carrying values of our inventory, or record inventory charges relating to discontinued products and excess or obsolete inventory.

Research and Product Development Expenses

Research and product development expenses increased 97% or $4.6 million to $9.2 million for the three months ended March 31, 2017 compared to $4.7 million for the three months ended March 31, 2016. The increase in research and product development expenses for the three months ended March 31, 2017 was primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of research and product development expenses related to the Legacy Zhone business for the current year period). We intend to continue to invest in research and product development to attain our strategic product development objectives while seeking to manage the associated costs through expense controls.

Selling, Marketing, General and Administrative Expenses

Selling, marketing, general and administrative expenses increased 149% or $6.3 million to $10.6 million for the three months ended March 31, 2017 compared to $4.3 million for the three months ended March 31, 2016. The increase in selling, marketing, general and administrative expenses was primarily due to the consummation of the Merger in September 2016 (which resulted in the inclusion of selling, marketing, general and administrative expenses related to Legacy Zhone business for the current year quarter), offset by higher commission expenses during the three months ended March 31, 2016.

Income Tax Provision

During the three months ended March 31, 2017 and 2016, no material provision or benefit for income taxes was recorded, due to our recurring operating losses and the significant uncertainty regarding the realization of our net deferred tax assets, against which we have continued to record a full valuation allowance.

OTHER PERFORMANCE MEASURES

In managing our business and assessing our financial performance, we supplement the information provided by our GAAP results with adjusted earnings before stock-based compensation, interest, taxes, and depreciation, or Adjusted EBITDA, a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss) plus (i) interest expense, (ii) provision (benefit) for taxes, (iii) depreciation and amortization, (iv) stock-based compensation, and (v) material non-recurring transactions or events, such as Merger transaction costs or a gain (loss) on sale of assets or impairment of fixed assets. We believe that the presentation of Adjusted EBITDA enhances the usefulness of our financial information by presenting a measure that management uses internally to monitor and evaluate our operating performance and to evaluate the effectiveness of our business strategies. We believe Adjusted EBITDA also assists investors and analysts in comparing our performance across reporting periods on a consistent basis because it excludes the impact of items that we do not believe reflect our core operating performance.

Adjusted EBITDA has limitations as an analytical tool. Some of these limitations are:


•	Adjusted EBITDA does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual requirements;


•	Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;


•	Adjusted EBITDA does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;

Table of Contents


•	although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;


•	non-cash compensation is and will remain a key element of our overall long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period; and


•	other companies in our industry may calculate Adjusted EBITDA and similar measures differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered in isolation or as a substitute for net income (loss) or any other performance measures calculated in accordance with GAAP or as a measure of liquidity. Management understands these limitations and compensates for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only supplementally.

Set forth below is a reconciliation of net loss to Adjusted EBITDA, which we consider to be the most directly comparable GAAP financial measure to Adjusted EBITDA (in thousands):



	Three Months Ended March 31,
	2017			2016
Net loss	$	(3,498	)	$	(3,761	)

Depreciation and amortization	1,181			268
Stock-based compensation	255			—
Adjusted EBITDA	$	(1,374	)	$	(3,974	)

LIQUIDITY AND CAPITAL RESOURCES

Our operations are financed through a combination of our existing cash, cash equivalents, available credit facilities, and sales of equity and debt instruments, based on our operating requirements and market conditions.

As of March 31, 2017, our cash and cash equivalents were $17.3 million compared to $17.9 million at December 31, 2016. Our cash and cash equivalents as of March 31, 2017 included $8.4 million in cash balances held by our Korean subsidiary. The $0.6 million decrease in cash and cash equivalents was attributable to net cash used in operating and financing activities of $0.7 million and $1.8 million, respectively, partially offset by the effect of exchange rate changes on cash of $0.8 million and net cash provided by investing activities of $1.1 million.

Ability to Continue as a Going Concern

The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP, assuming we will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Accordingly, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability of DZS to continue as a going concern.

We have incurred significant losses to date and our losses from operations may continue. We incurred net losses of $3.5 million and $15.3 million for the three months ended March 31, 2017 and the year ended December 31, 2016, respectively. We had accumulated deficit of $23.7 million and working capital of $55.2 million as of March 31, 2017. As of March 31, 2017, we had approximately $17.3 million in cash and cash equivalents, which included $8.4 million in cash balances held by our Korean subsidiary, and $31.5 million in aggregate principal amount of outstanding borrowings under our credit facility with Wells Fargo Bank, our short-term debt obligations and our loans from DNI. In addition, we had $5.7 million in aggregate borrowing availability under our credit facilities as of March 31, 2017. We had $6.0 million committed as security for letters of credit under these facilities as of March 31, 2017. Due to the amount of short-term debt obligations maturing within the next 12 months and our recurring operating losses, our cash resources may not be sufficient to settle these short-term debt obligations. Our ability to continue as a "going concern" is dependent on many factors, including, among other things, our ability to comply with the covenants in our existing debt agreements, our ability to cure any defaults that occur under our debt agreements or to obtain waivers or forbearances with respect to any such defaults, and our ability to pay, retire, amend, replace or refinance our

Table of Contents

indebtedness as defaults occur or as interest and principal payments come due. Although the process of amending, replacing or refinancing our short-term debt obligations is ongoing and we are in active discussions with multiple parties, there is no guarantee that they will result in transactions that are sufficient to provide us with the required liquidity to remove the substantial doubt as to our ability to continue as a going concern. If we are unable to amend, replace, refinance our short-term debt obligations or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, we may experience material adverse impacts on our business, operating results and financial condition.

We have continued our focus on cost control and operating efficiency along with restrictions on discretionary spending. In order to meet our liquidity needs and finance our capital expenditures and working capital needs for our business, we may be required to sell assets, issue debt or equity securities, purchase credit insurance or borrow on potentially unfavorable terms. In addition, we may be required to reduce the scope of our planned product development, reduce sales and marketing efforts and reduce our operations in low margin regions, including reductions in headcount. Based on our current plans and business conditions, we believe that our focused operating expense discipline along with our existing cash, cash equivalents and available credit facilities will be sufficient to satisfy our anticipated cash requirements for at least the next 12 months, however the factors discussed above raise substantial doubt about our ability to continue as a going concern.

Operating Activities

Net cash provided by operating activities for the three months ended March 31, 2017 consisted of a net loss of $3.5 million, adjusted for non-cash charges totaling $2.3 million and an increase in net operating assets totaling $0.5 million. The most significant components of the changes in net operating assets were an increase in accounts receivable of $1.3 million and an increase in inventory of $3.7 million offset by a decrease in accounts payable of $6.7 million. The increase in accounts receivable was primarily the result of the timing of receivables collections during the current year period. The increase in inventory was due to slower utilization of inventory in the current year period. The decrease in accounts payable was mainly due to reclassification of certain balances to short-term debt.

Net cash used in operating activities for the three months ended March 31, 2016 consisted of a net loss of $3.8 million, adjusted for non-cash charges totaling $0.1 million and an decrease in net operating assets totaling $3.9 million. The most significant components of the changes in net operating assets were an increase in accrued expenses of $11.9 million offset by an increase in prepaid expenses and other current assets of $8.7 million.

Investing Activities

Net cash provided by investing activities for the three months ended March 31, 2017 consisted of a decrease in restricted cash of $0.7 million and proceeds from short-term investments of $1.0 million, offset by purchases of property and equipment of $0.4 million.

Net cash used in investing activities for the three months ended March 31, 2016 consisted of an increase in short-term and long-term loans to others of $1.6 million and an increase in restricted cash of $0.8 million, offset by a decrease in short-term and long-term loans of $0.3 million.

Financing Activities

Net cash used in financing activities for the three months ended March 31, 2017 consisted of cash used in repayments of borrowings of $4.4 million, offset by proceeds from short-term borrowings of $2.6 million.

Net cash provided by financing activities for the three months ended March 31, 2016 consisted of proceeds from short-term borrowings and proceeds from long-term borrowings of $1.1 million and $1.8 million, respectively.

Cash Management

Our primary source of liquidity comes from our cash and cash equivalents which totaled $17.3 million at March 31, 2017 , as well as our credit facilities, under which we had aggregate borrowing availability of $5.8 million as of March 31, 2017, and under which $3.6 million was committed as security for letters of credit as of March 31, 2017. Our cash and cash equivalents as of March 31, 2017 included $8.4 million in cash balances held by our Korean subsidiary.

WFB Facility

As of March 31, 2017, we had a $25.0 million credit facility (the "WFB Facility") with Wells Fargo Bank ("WFB"). Under the WFB Facility, we have the option of borrowing funds at agreed upon interest rates. The amount that we are able to borrow under the WFB Facility varies based on eligible accounts receivable and inventory, as defined in the WFB Facility, as long as

Table of Contents

the aggregate amount outstanding does not exceed $25.0 million less the amount committed as security for letters of credit. To maintain availability of funds under the WFB Facility, we pay a commitment fee on the unused portion. The commitment fee is 0.25% per annum and is recorded as interest expense.

As of March 31, 2017, we had $0.2 million in outstanding borrowings under the WFB Facility, and $3.6 million was committed as security for letters of credit. We had $5.7 million of borrowing availability under the WFB Facility as of March 31, 2017. The amounts borrowed under the WFB Facility bear interest, payable monthly, at a floating rate equal to the three-month LIBOR plus a margin based on our average excess availability (as calculated under the WFB Facility). The interest rate on the WFB Facility was 0.0365% at March 31, 2017. The maturity date under the WFB Facility is March 31, 2019.

Our obligations under the WFB Facility are secured by substantially all of our personal property assets and those of our subsidiaries that guarantee the WFB Facility, including our intellectual property. The WFB Facility contains certain financial covenants, and customary affirmative covenants and negative covenants. If we default under the WFB Facility due to a covenant breach or otherwise, WFB may be entitled to, among other things, require the immediate repayment of all outstanding amounts and sell our assets to satisfy the obligations under the WFB Facility. In the past we have violated the covenants in our former credit facility and received waivers for these violations. On July 3, 2017, we executed an agreement with WFB to extend the due date for delivery for our audited financial statements for the year ended December 31, 2016 to September 27, 2017. As of March 31, 2017, we were in compliance with the covenants under the WFB Facility. We make no assurances that we will be in compliance with these covenants in the future.

Bank and Trade Facilities - Foreign Operations

Certain of our foreign subsidiaries have entered into various financing arrangements with foreign banks and other lending institutions consisting primarily of revolving lines of credit, trade facilities, term loans and export development loans. These facilities are renewed on an annual basis and are generally secured by a security interest in certain assets of the applicable foreign subsidiaries. Payments under such facilities are made in accordance with the given lender’s amortization schedules. As of March 31, 2017 and December 31, 2016, we had an aggregate outstanding balance of $24.5 million and $17.6 million, respectively, under such financing arrangements, and the interest rate per annum applicable to outstanding borrowings under these financing arrangements as of March 31, 2017 and December 31, 2016 ranged from 2.16% to 4.69% and 1.92% to 4.08%, respectively.

Related-Party Debt

In connection with the Merger, on September 9, 2016, we entered into a loan agreement with DNI for a $5.0 million unsecured subordinated term loan facility. Under the loan agreement, we were permitted to request drawdowns of one or more term loans in an aggregate principal amount not to exceed $5.0 million. As of March 31, 2017, $5.0 million in term loans was outstanding under the facility. Such term loans mature in September 2021 and are pre-payable at any time by us without premium or penalty. The interest rate as of March 31, 2017 under this facility was 4.6% per annum.

In addition, we borrowed $1.8 million from DNI for capital investment in February 2016, which amount was outstanding as of March 31, 2017. This loan matured in March 2017 with an option of renewal by mutual agreement, and bore interest at a rate of 6.9% per annum, payable annually. Effective February 27, 2017, we amended the terms of this loan to extend the repayment date from March 2017 to March 2018 and to reduce the interest rate from 6.9% to 4.6% per annum.

On June 23, 2017, we borrowed $3.5 million from Solueta, an affiliate of DNI, which amount was outstanding as of June 30, 2017. This loan matures in November 2017 and bears interest at a rate of 4.6% per annum, payable monthly.

Future Requirements and Funding Sources

Our fixed commitments for cash expenditures consist primarily of payments under operating leases, inventory purchase commitments, and payments of principal and interest for debt obligations.

From time to time, we may provide or commit to extend credit or credit support to our customers. This financing may include extending the terms for product payments to customers. Any extension of financing to our customers will limit the capital that we have available for other uses.

Our accounts receivable, while not considered a primary source of liquidity, represent a concentration of credit risk because a significant portion of the accounts receivable balance at any point in time typically consists of a relatively small number of customer account balances. As of March 31, 2017, two customers accounted for 18% and 16% of net accounts receivables, respectively, and receivables from customers in countries other than the United States represented 85% of net accounts

Table of Contents

receivable. We do not currently have any material commitments for capital expenditures, or any other material commitments aside from operating leases for our facilities, inventory purchase commitments and debt.

As discussed above in "Ability to Continue as a Going Concern", there is substantial doubt about our ability to continue as a going concern. The accompanying condensed consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Operating Leases

The operating lease amounts shown above represent primarily off-balance sheet arrangements. For operating lease commitments, a liability is generally not recorded on our balance sheet unless the facility represents an excess facility for which an estimate of the facility exit costs has been recorded on our balance sheet, net of estimated sublease income. For operating leases that include contractual commitments for operating expenses and maintenance, estimates of such amounts are included based on current rates. Payments made under operating leases will be treated as rent expense for the facilities currently being utilized.

Purchase Commitments

The purchase commitments shown above represent non-cancellable inventory purchase commitments as of March 31, 2017. On July 16, 2017, we reached an agreement with a supplier to cancel a purchase arrangement for certain inventory which was committed to through 2020. Under the settlement, we are no longer required to fulfill our commitment to purchase $4.3 million in inventory. In connection with the settlement, we also entered into a technical support services arrangement with the supplier through April 30, 2021.

WFB Facility

Obligations under our WFB Facility have been recorded as a liability on our balance sheet and comprise the $0.2 million in outstanding borrowings under the WFB Facility as of March 31, 2017. The amount shown above represents the scheduled principal repayment under the WFB Facility, but not the associated interest payments which may vary based on changes in market interest rates. At March 31, 2017, the interest rate on the WFB Facility was 0.0365%. See above under "Cash Management - WFB Facility" for further information about the WFB Facility.

Short-term Debt

Obligations under our short-term credit facilities was $24.5 million as of March 31, 2017. The amount shown above represents scheduled principal repayments under these facilities, but not the associated interest payments which may vary based on changes in market interest rates. At March 31, 2017, the interest rate per annum applicable to outstanding borrowings under the trade facilities of our foreign subsidiaries ranged from 2.16% to 4.69%. The amount shown above excludes $1.8 million in short-term debt obligations to related parties, which is included in the table as related-party debt (as discussed further below).

See above under “Cash Management - Bank and Trade Facilities - Foreign Operations” for further information about these facilities.

Related-Party Debt

Table of Contents

As of March 31, 2017, we had borrowed an aggregate of $6.8 million from DNI, of which $5.0 million and $1.8 million mature in September 2021 and March 2018, respectively, and the interest rate per annum applicable to these borrowings was 4.6%. The amounts listed in the table above reflect the amendment in February 2017 to the DNS capital investment loan, which among other matters extended the repayment date of the loan from March 2017 to March 2018. The table does not include the $3.5 million borrowed from Solueta, an affiliate of DNI, in June 2017. See above under “Cash Management" for further information about our related-party debt.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Concentration of Credit Risk

Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, and accounts receivable. Cash and cash equivalents consist principally of demand deposit and money market accounts. Cash and cash equivalents are principally held with various domestic financial institutions with high credit standing. We perform ongoing credit evaluations of our customers and generally do not require collateral. Allowances are maintained for potential doubtful accounts.

We anticipate that our results of operations in any given period may depend to a large extent on sales to a small number of large accounts. As a result, our revenue for any quarter may be subject to significant volatility based upon changes in orders from one or a small number of key customers.

As of March 31, 2017, two customers represented 18% and 16% of net accounts receivable, respectively. As of December 31, 2016, two customers represented 13% (a related-party) and 10% of net accounts receivable.

As of March 31, 2017, and December 31, 2016, receivables from customers in countries other than the United States represented 85% and 87%, respectively, of net accounts receivable.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to our variable rate outstanding debt. As of March 31, 2017, our outstanding debt balance was $31.5 million, which comprised of $0.2 million in principal amount of borrowings under our WFB Facility, $24.5 million in aggregate principal amount of borrowings under our short-term credit facilities and $6.8 million in loans from DNI (which bear interest at a fixed rate).

Amounts borrowed under the WFB Facility bear interest, payable monthly, at a floating rate equal to the three-month LIBOR plus a margin based on our average excess availability (as calculated under the WFB Facility). As of March 31, 2017, the interest rate on the WFB Facility was 0.0365%. Amounts borrowed under our short-term credit facilities bear interest ranging from 2.16% to 4.69% as of March 31, 2017. Assuming the outstanding balance on our variable rate debt remains constant over a year, a 2% increase in the interest rate would decrease pre-tax income and cash flow by approximately $0.5 million.

Foreign Currency Risk

We transact business in various foreign countries, and a significant portion of our assets is located in Korea. We have sales operations throughout Europe, Asia, the Middle East and Latin America. We are exposed to foreign currency exchange rate risk associated with foreign currency denominated assets and liabilities, primarily intercompany receivables and payables. Accordingly, our operating results are exposed to changes in exchange rates between the U.S. dollar and those currencies. During the three months ended March 31, 2017 and 2016, we did not hedge any of our foreign currency exposure.

We have performed a sensitivity analysis as of March 31, 2017 using a modeling technique that measures the impact on the balance sheet arising from a hypothetical 10% adverse movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The sensitivity analysis indicated that a hypothetical 10% adverse movement in foreign currency exchange rates would result in a foreign exchange loss of $2.4 million at March 31, 2017. This sensitivity analysis assumes a parallel adverse shift in foreign currency exchange rates, which do not always move in the same direction. Actual results may differ materially.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance of achieving the objective that information required to be disclosed in our reports filed or submitted pursuant to the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Co-Chief Executive Officers and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2017, the end of the period covered by this report. The evaluation was done under the supervision and with the participation of management, including our Co-Chief Executive Officers and our Chief Financial Officer. Based upon this evaluation, our Co-Chief Executive Officers and Chief Financial Officer concluded that, because of the material weaknesses in our internal control over financial reporting that existed as of December 31, 2016, as described below, our disclosure controls and procedures were not effective as of March 31, 2017.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses that management previously identified in connection with its evaluation of our internal control over financial reporting as of December 31, 2016 were as follows: we did not maintain an effective control environment as there was an insufficient complement of personnel with appropriate accounting knowledge, experience and competence, resulting in incorrect application of generally accepted accounting principles. This material weakness contributed to the following material weaknesses. We did not maintain effective controls over our financial close process. Also, we did not design and maintain effective controls over the review of supporting information to determine the completeness and accuracy of the accounting for complex transactions, specifically related to the business combination that occurred on September 9, 2016, which resulted in an incorrect application of generally accepted accounting principles that resulted in material misstatements and a restatement of our unaudited condensed consolidated financial statements for the three and nine months period ended September 30, 2016. Additionally, these material weaknesses could result in a misstatement in the financial statements that would result in a material misstatement in the annual or interim consolidated financial statements that would not be prevented or detected.

In light of the material weakness described above, and based on the criteria set forth in Internal Control —Integrated Framework (2013) issued by the Committee Sponsoring Organizations of the Treadway Commission (COSO), our management concluded that our internal control over financial reporting was not effective as of December 31, 2016.

As of the date of this report, we are re-assessing the design of our controls and modifying processes related to the accounting for significant and unusual transactions as well as enhancing monitoring and oversight controls in the application of applicable accounting guidance related to such transactions. In connection therewith, we anticipate that we will hire additional accounting personnel with relevant skills, training and experience, and conduct further training of accounting and finance personnel.

Changes in Internal Control over Financial Reporting

Except as described above, there were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Merger-related integration activities may lead us to modify certain internal controls in future periods.

Inherent Limitations on Effectiveness of Controls

Our management, including our Co-Chief Executive Officers and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, "Item 1A, Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016, which could materially affect our business, financial condition or future results. There have been no material changes to the risk factors described in the "Risk Factors" section in our Annual Report on Form 10-K for the year ended December 31, 2016. The risks described in our Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
