Notes to Unaudited Condensed Consolidated Financial Statements

(1)	Organization and Summary of Significant Accounting Policies

(a)

Description of Business

DASAN Zhone Solutions, Inc. (referred to, collectively with its subsidiaries, as “DZS” or the “Company”) is a global provider of ultra-broadband network access solutions and communications platforms deployed by advanced Tier 1, 2 and 3 service providers and enterprise customers. 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 900 customers in more than 80 countries worldwide.

DZS was incorporated under the laws of the state of Delaware in June 1999, under the name Zhone Technologies, Inc. On September 9, 2016, the Company acquired Dasan Network Solutions, Inc., a California corporation (“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.

The Company is headquartered in Oakland, California with flexible in-house production facilities in Seminole, Florida and Hanover, Germany (acquired as part of the Keymile Acquisition (defined below) in January 2019), and contract manufacturers located in China, India, Korea and Vietnam. The Company also maintains offices to provide sales and customer support at global locations.

(b)

DNI Ownership

As of September 30, 2019, DNI owned approximately 44.4% of the outstanding shares of the Company's common stock. As a result, DNI is able to significantly influence corporate and management policies and the outcome of any corporate transaction or other matter submitted to the Company’s stockholders for approval. Such transactions may include mergers and acquisitions, sales of all or some of the Company’s assets or purchases of assets, and other significant corporate transactions. The interests of DNI may not coincide with the interests of the Company's other stockholders or with holders of the Company's indebtedness. See Note 11 and Note 15 to the unaudited condensed consolidated financial statements for additional information.

(c)

Basis of Presentation

For a complete description of what the Company believes to be the critical accounting policies and estimates used in the preparation of its unaudited condensed consolidated financial statements, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The unaudited 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, 2018 filed with the Securities and Exchange Commission (“SEC”) on March 12, 2019.

(d)

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

(e)

Reclassifications

For the three and nine months ended September 30, 2018, certain previously reported statement of comprehensive income (loss) and statement of cash flows amounts have been adjusted for certain immaterial reclassifications to correctly reflect: (i) cost of products and services to related parties; and (ii) changes in accounts receivable and contract assets.

(f)

Contract Balances

The Company records contract assets when it has a right to consideration and records accounts receivable when it has an “unconditional” right to consideration. Contract liabilities consist of cash payments received (or unconditional rights to receive cash) in advance of fulfilling performance obligations.

The opening and closing balances of contract assets and contract liabilities related to contracts with customers are as follows:

	Contract Assets			Contract Liabilities
Opening, January 1, 2019	$	12,175		$	10,312
Closing, September 30, 2019		10,328			6,206
Decrease	$	(1,847	)	$	(4,106	)

The amount of revenue recognized in the three months ended September 30, 2019 that was included in the prior period contract liability balance was $1.7 million. The amount of revenue recognized in the nine months ended September 30, 2019 that was included in the January 1, 2019 contract liability balance was $7.3 million. This revenue consists of services provided to customers who had prepaid for those services prior to the current year.

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents which totaled $47.9 million at September 30, 2019, including $7.4 million held by its international subsidiaries. Cash and cash equivalents consist of financial deposits and money market accounts that are principally held with various domestic and international financial institutions with high credit standing.

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.

As of September 30, 2019, two customers represented 17% and 12% of net accounts receivable, respectively. As of December 31, 2018, two customers represented 11% and 10% of net accounts receivable, respectively.

As of September 30, 2019 and December 31, 2018, receivables from customers in countries other than the United States represented 94% and 88%, respectively, of net accounts receivable.

Business Combinations

The Company allocates the fair value of purchase consideration to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets and certain tangible assets such as inventory.

Critical estimates in valuing certain tangible and intangible assets include but are not limited to future expected cash flows from the underlying assets and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

(i)

Defined Benefit Plans and Plan Assumptions

The Company provides certain defined benefit pension plans to employees in Germany. Pension accounting is intended to reflect the recognition of future benefit costs over the employees' average expected future service to the Company based on the terms of the plans and investment and funding decisions. To estimate the impact of these future payments and the Company’s decisions concerning funding of these obligations, the Company is required to make assumptions using actuarial concepts within the framework of U.S. GAAP. Two critical assumptions are the discount rate and the expected long-term return on plan assets. Other important assumptions include expected future salary increases, expected future increases to benefit payments, expected retirement dates, employee turnover, retiree mortality rates and portfolio composition. The Company evaluates these assumptions at least annually.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases as modified subsequently by ASUs 2018-01, 2018-10, 2018-11, 2018-20 and 2019-01 (“ASC 842”), which introduces the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. ASC 842 requires that lease arrangements longer than 12 months’ result in an entity recognizing an asset and liability, with respect to such lease arrangement, among other changes.

The Company adopted the new standard on January 1, 2019, the first day of fiscal 2019, using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases.

The Company has elected to use a certain package of practical expedients permitted under the transition guidance within ASC 842. Those practical expedients are as follows:

•

The Company did not reassess (i) whether expired or existing contracts contain leases under the new definition of a lease; (ii) lease classification for expired or existing leases; and (iii) whether previously capitalized initial direct costs would qualify for capitalization under ASC 842.

•

The Company did not reassess a lease whose term is 12 months or less and does not include a purchase option that the lessee is reasonably certain to exercise.

•

The Company did not elect to use hindsight for transition when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset.

•

For all asset classes, the Company elected to not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less.

•

For all asset classes, the Company elected to not separate non-lease components from lease components to which they relate and has accounted for the combined lease and non-lease components as a single lease component.

The Company applies significant judgment in considering all relevant factors that create an economic benefit (e.g., contract-based, asset-based, entity-based, and market-based, among others) as of the commencement date in determining the initial lease term and future lease payments. For example, the Company exercises judgment in determining whether renewal periods will be exercised during the initial measurement process. If the Company believes it will exercise the renewal option, and the lease payments associated with the renewal periods are known or calculable, such renewal lease payments would be included in the initial measurement of the lease liability. Otherwise, even if the Company believes that it will exercise the renewal period, if the renewal payments are unknown or not calculable, they would not be included until they become known or calculable at which time the Company would remeasure the remaining lease payments similar to a lease modification.

Adoption of ASC 842 resulted in the balance sheet recognition of right of use assets and lease liabilities of approximately $22.5 million as of January 1, 2019. Adoption of ASC 842 did not materially impact the Company’s unaudited condensed consolidated statements of comprehensive income (loss) and cash flows. See Note 14 in the notes to unaudited condensed consolidated financial statements.

Income Tax Effects within Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”). The adoption of this standard on January 1, 2019 did not have a material impact on the Company’s condensed consolidated financial statements, since the Company did not elect to reclassify the income tax effects of the Tax Act from accumulated other comprehensive income to retained earnings.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. The ASU requires the Company to disaggregate the service cost component from the other components of net periodic benefit costs and requires the Company to present the other components of net periodic benefit cost in other income, net. The standard is effective for annual and interim periods beginning after December 31, 2017, and retrospective application is required. The Company adopted this guidance during the first quarter of 2019 without any retrospective adjustments since the underlying pension obligations were acquired through the Keymile Acquisition in 2019. The interest cost, which is the only component of net periodic post-retirement cost, is recognized in Other income (loss), net in the condensed consolidated statement of comprehensive income (loss).

Other Recent Accounting Pronouncements Not Yet Adopted

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other Internal-Use Software - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement. The update reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard is effective for annual and interim periods beginning after December 15, 2019, and retrospective or prospective application is permitted. We are currently evaluating the impact of adoption of this ASU, but it is not expected to have a material effect on our condensed consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the Company to measure and recognize expected credit losses for financial assets held and not accounted for at fair value through net income. In November 2018, April 2019 and May 2019, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, and ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief, which provided additional implementation guidance on the previously issued ASU. The updated guidance is effective for the Company on January 1, 2020, and requires a modified retrospective adoption method. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this new guidance on its consolidated financial statements.

In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairment. The updated guidance is effective for the Company on January 1, 2020, and will be adopted accordingly. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this new guidance on its consolidated financial statements.

On August 28, 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. The updated guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this new guidance on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The updated guidance is effective for the Company on January 1, 2021, with early adoption permitted. The Company is currently assessing the potential impact of adopting this new guidance on its consolidated financial statements.

(2)	Business Combinations

Keymile Acquisition

On January 3, 2019, ZTI Merger Subsidiary III Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“ZTI”), acquired all of the outstanding shares of Keymile GmbH (“Keymile”), a limited liability company organized under the laws of Germany, from Riverside KM Beteiligung GmbH (“Riverside”), a limited liability company organized under the laws of Germany, pursuant to a share purchase agreement (the “Keymile Acquisition”).

The allocation of the purchase price was based upon a preliminary valuation, and the Company’s estimates and assumptions are subject to refinement, within the measurement period (up to one year from the Acquisition Date). Measurement period adjustments, with the corresponding adjustment to the bargain purchase gain or goodwill, will be recorded in the reporting period in which the adjustment to the provisional amounts are determined based upon the final valuation.

The aggregate cash purchase price paid for all of the shares of Keymile and certain of its subsidiaries, was €10,250,000 (approximately $11.8 million), subject to adjustment for the lockbox mechanism described below. The Company also assumed pension obligations of approximately $12.7 million, net of pension assets of $3.5 million. Following the closing of the Keymile Acquisition, Keymile became the Company’s wholly owned subsidiary. The Keymile Acquisition agreement also provided for a lockbox mechanism such that normal operations were observed by Keymile management and any excess cash flows generated from operating activities for the period from October 1, 2018 to December 31, 2018 remained with Keymile following the closing, with the Company as the beneficiary, as the purchaser of Keymile. At December 31, 2018, cash received from the lockbox mechanism amounted to $2.5 million.

On October 1, 2018, as a condition for the Keymile Acquisition, Riverside extended a €4.0 million ($4.4 million, which represents the cash and cash equivalents and short-term debt, in the “Allocation of Purchase Consideration” table below) working capital loan to Keymile. The working capital loan bears interest at a rate of 3.5% per annum and is scheduled for repayment in two equal installments in April and November 2019. The first payment of €2.0 million ($2.2 million) was made in April 2019 and the balance is due in November 2019. As of September 30, 2019, the outstanding balance under this working capital loan was €2.0 million ($2.2 million). Subsequently in November 2019, the Company fully repaid all the outstanding borrowings under this working capital loan.

Keymile is a leading solution provider and manufacturer of telecommunication systems for broadband access. The Company believes Keymile strengthens its portfolio of broadband access solutions, which now includes a series of multi-service access platforms for FTTx network architectures, including ultra-fast broadband copper access based on VDSL/Vectoring and G. Fast technology.

A summary of the preliminary estimated purchase price allocation to the fair value of assets acquired and liabilities assumed is as follows (in thousands):

Purchase consideration
Cash consideration	$	11,776
Working capital adjustment: cash received from lockbox mechanism		(2,497	)
Adjusted purchase consideration	$	9,279

The following summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for the Keymile Acquisition (in thousands):

Allocation of purchase consideration
Current assets
Cash and cash equivalents	$	4,582
Accounts receivable - trade, net		6,820
Other receivables		798
Inventories		9,943
Property, plant and equipment		983
Other assets		163
Intangible assets		12,030
Accounts payable - trade		(3,303	)
Short-term debt		(4,582	)
Contract liabilities		(364	)
Accrued liabilities		(3,614	)
Deferred tax liabilities		(1,071	)
Pension obligations		(12,656	)
Other long term liabilities		(116	)
Bargain purchase gain		(334	)
Total purchase consideration	$	9,279

The purchase price allocation resulted in the recognition of a gain on bargain purchase of approximately $0.3 million, which was included in the unaudited condensed consolidated statements of comprehensive income (loss) for the nine months ended September 30, 2019. The gain on bargain purchase was the result of the preliminary fair value of the identifiable net assets acquired exceeding the purchase price paid for the Keymile Acquisition which was reduced by the lockbox mechanism.

The estimated weighted average useful lives of the acquired property, plant and equipment is 5 years. Depreciation is calculated using the straight-line method.

The following table represents the preliminary estimated fair value and useful lives of identifiable intangible assets acquired:

	Estimated Fair Value (in thousands)		Estimated Useful Life
Intangible assets acquired
Customer relationships	$	3,667	5 years
Trade name		3,208	5 years
Technology - developed core		5,155	5 years
Total intangible assets	$	12,030

As of the valuation date, there was value attributable to Keymile’s existing customer relationships. Keymile’s key customer base is made up of independent telecommunication service providers and network operators, a base of customers that have seen growth since 2012. Keymile is seen as a market leader and historically has had low customer attrition. In addition, switching costs are considered to be high due to the disruption of switching platforms as well as the additional training necessary. The Company valued the customer relationships using the Income Approach, specifically the Multi-Period Excess Earnings Method (“MPEEM”).

The Company utilized the Relief from Royalty Method (“RFRM”) to value the tradename and developed technology. The RFRM assumes that the value of the asset equals the amount a third party would pay to use the asset and capitalize on the related benefits of the asset. Therefore, a revenue stream for the asset is estimated, and then an appropriate royalty rate is applied to the forecasted revenue to estimate the pre-tax income associated with the asset. The pre-tax income is then tax-effected to estimate the after-tax net income associated with the asset. Finally, the after tax net income is discounted to the present value using an appropriate rate of return that considers both the risk of the asset and the associated cash flow estimates.

Pro Forma Financial Information

The unaudited pro forma information for the periods set forth below gives effect to the Keymile Acquisition as if it had occurred as of January 1, 2018. The unaudited pro forma financial information has been prepared by management for illustrative purposes only and does not purport to represent what the results of operations, financial condition or other financial information of the Company would have been if the Keymile Acquisition had occurred on January 1, 2018 or what such results or financial condition will be for any future periods. The unaudited pro forma financial information is based on estimates and assumptions and on the information available at the time of the preparation thereof. These estimates and assumptions may change, be revised or prove to be materially different, and the estimates and assumptions may not be representative of facts existing at the time of the Keymile Acquisition. The pro forma adjustments primarily relate to acquisition related costs, amortization of acquired intangibles and interest expense related to financing arrangements. Below is the pro forma financial information (in thousands):

	Three Months Ended		Nine Months Ended
	September 30, 2018		September 30, 2018
Pro forma net revenues	$	84,870	$	242,086
Pro forma net income attributable to DASAN Zhone Solutions, Inc.		726		2,885

Acquisition of the Non-controlling Interest in DZS Japan

On July 31, 2019, the Company acquired the remaining 30.94% non-controlling interest of DZS Japan, Inc. (“DZS Japan”), and DZS Japan became a wholly owned subsidiary of the Company. The Company acquired the remaining interest in DZS Japan for total cash consideration of $950,000, consisting entirely of payments to the former shareholder (Handysoft). This transaction resulted in a decrease to “Additional paid-in capital” of $127,000, a decrease to “Non- controlling interest” of $823,000, and a total impact of $950,000 in the unaudited condensed consolidated balance sheet as of September 30, 2019.

(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 condensed consolidated balance sheet as of September 30, 2019 and the consolidated balance sheet as of December 31, 2018, but require disclosure of their fair values: cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable, accrued liabilities, lease liabilities and debt. The carrying values of financial instruments such as cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and accrued liabilities approximate their fair values based on their short-term nature. The carrying value of the Company's lease liabilities and debt approximates their fair values based on the current rates available to the Company for debt of similar terms and maturities.

(4)	Cash, Cash Equivalents and Restricted Cash

As of September 30, 2019 and December 31, 2018, the Company's cash and cash equivalents consisted of financial deposits and money market accounts that are principally held with various domestic and international financial institutions with high credit standing. Restricted cash consisted primarily of cash restricted for performance bonds, warranty bonds and collateral for borrowings.

(5)	Balance Sheet Details

Accounts receivable, net consisted of the following (in thousands):

Depreciation expense associated with property and equipment for the three and nine months ended September 30, 2019 was $0.5 million and $1.5 million, respectively. Depreciation expense for the three and nine months ended September 30, 2018 was $0.4 million and $1.2 million, respectively.

The Company receives grants from various government entities mainly to support capital expenditures. Such grants are deferred and are generally refundable to the extent the Company does not utilize the funds for qualifying expenditures. Once earned, the Company records the grants as a contra amount to the assets and amortizes such amount over the useful lives of the related assets as a reduction to depreciation expense.

PNC Bank Facility

On February 27, 2019, the Company and ZTI (collectively, the “Borrowers”), and certain direct and indirect subsidiaries of the Borrowers, as guarantors, entered into a Revolving Credit, Term Loan, Guaranty and Security Agreement (the “Domestic Credit Agreement”) and an Export-Import Revolving Credit, Guaranty and Security Agreement (the “Ex-Im Credit Agreement,” and together with the Domestic Credit Agreement, the “Credit Agreements”), in each case with PNC Bank, National Association (“PNC”) and Citibank, N.A. as lenders, and PNC as agent for the lenders (the “PNC Facility”), which replaced the Company’s former senior secured credit facilities with Wells Fargo Bank (the “Former WFB Facility”).

The Credit Agreements provide for a $25.0 million term loan and a $15.0 million revolving line of credit (including sub-facilities for export-import transactions, letters of credit and swing loans). The amount the Company is able to borrow on the revolving line of credit at any time is based on eligible accounts receivable and other conditions, less certain reserves. Borrowings under the PNC Facility bear interest at the Company’s option, at either (i) a base rate equal to the highest of the federal funds rate plus 0.50%, PNC’s prime rate, or the daily LIBOR rate plus 1.00%, or (ii) the LIBOR rate for the applicable interest period, subject to a floor of 1.00% (with respect to the term loans only), plus in each case, an applicable margin. The applicable margin for term loans is 5.00% for base rate loans and 6.00% for LIBOR rate loans, and the applicable margin for borrowings under the revolving line of credit is 1.50% for base rate loans and 2.50% for LIBOR rate loans.

The Company used a portion of the funds borrowed from the term loan under the Credit Agreements to (i) repay $5.0 million in principal amount of existing related-party indebtedness with DNI plus accrued interest, (ii) repay $1.5 million in outstanding borrowings under the Company’s former revolving line of credit plus accrued interest and fees and cash collateralize $3.6 million in outstanding letters of credit under the Former WFB Facility, and (iii) repay $5.6 million short-term debt in Korea and Japan. The Company intends to use the remaining funds for ongoing working capital needs. Obligations under the Credit Agreements are secured by substantially all of the personal property assets of the Borrowers and the subsidiaries that guarantee the Credit Agreements, including their intellectual property.

The maturity date under the Credit Agreements is February 27, 2022. The term loan under the Credit Agreements is repayable in eight quarterly installments of $625,000 beginning June 30, 2019, followed by quarterly installments of $937,500 beginning on June 30, 2021, with all remaining unpaid principal and accrued interest due on the maturity date.

The Credit Agreements contain certain covenants, limitations, and conditions with respect to the Borrowers and their subsidiaries, including a maximum leverage ratio, a minimum fixed charge coverage ratio, and a minimum liquidity covenant, as well as financial reporting obligations, and customary events of default. If an event of default occurs, the agent and lenders will be entitled to take various actions, including requiring the immediate repayment of all outstanding amounts under the Credit Agreements, terminating commitments to make additional advances and selling the assets of the Borrowers and their subsidiary guarantors to satisfy the obligations under the Credit Agreements. At September 30, 2019, the Company was not in compliance with the maximum leverage ratio financial covenant in the Credit Agreements, which represents an event of default thereunder. On November 8, 2019, the Company obtained a waiver of the foregoing event of default from the lenders under the Credit Agreements. As a condition for the issuance of the waiver, the Company voluntarily prepaid $10.0 million of the outstanding term loan and paid a one-time fee of $150,000. Uncertainty exists as to the Company’s ability to meet these financial covenants at the respective reporting dates during the next twelve months. As a result, the Company is in the process of renegotiating these financial covenants with the banks; however, there is no assurance that the Company will be able to successfully complete such renegotiations. If the Company violates covenants in the Credit Agreements or the contemplated amended covenants, the Company could be required to repay the amounts then outstanding under the Credit Agreements.

As of September 30, 2019, the Company had $23.8 million in outstanding term loan borrowings under its PNC Facility, and no outstanding borrowings under the revolving line of credit. The interest rate on the term loan was 8.12% at September 30, 2019. Deferred financing costs of $1.5 million has been netted against the aggregate principal amount of the PNC term loan in the unaudited condensed consolidated balance sheet as of September 30, 2019. On July 2, 2019, $4.4 million in outstanding borrowings under the revolving line of credit (which represented all outstanding borrowings under the revolving line of credit) was repaid in full.

Former Wells Fargo Bank Facility

On February 27, 2019, in connection with the entry into the PNC Facility, the Company repaid $1.5 million in principal amount of outstanding borrowings plus accrued interest and fees under the Former WFB Facility and cash collateralized $3.6 million in outstanding letters of credit under the Former WFB Facility and terminated the Former WFB Facility.

Working Capital Loan

(9)	Defined Benefit Plans

The Company provides certain defined benefit pension plans in Germany for active and former employees of Keymile and their surviving dependents. These benefits were promised upon an employee either reaching retirement age or becoming disabled. Benefits paid depend on an employee’s years of service and annual earnings. These plans were frozen as of September 30, 2003 and have not been offered to new employees after that date. Employees who were already covered by such plans ceased earning benefits under such plans from the freeze date forward. The benefit obligations are determined separately for each plan by estimating the present value of future benefits that employees have earned in prior periods. Given that all plans are frozen; the Company does not have any current service costs to recognize within its defined benefit obligation or pension expense.

The only component of pension expense relates to $0.1 million of interest expense on the defined benefit pension plans, which is recognized in Other income (loss), net in the condensed consolidated statement of comprehensive income (loss). The interest expense is determined by multiplying the defined benefit obligation by the discount rate used to determine the defined benefit obligation. Actuarial gains and losses from changes in assumptions are included in Other comprehensive loss in the condensed consolidated statement of comprehensive income (loss).

The following key actuarial assumptions were made in determining the benefit obligation:

	September 30, 2019
Discount rate	1.20%
Rate of pension increase	1.70%
Retirement age	63-67 years

As of September 30, 2019, the Company’s employee benefit obligations under the defined benefit plans is approximately $13.3 million, net of pension assets of $3.4 million which is under a reinsurance contract policy. During the three and nine months ended September 30, 2019, the Company made no cash contributions to the defined benefit plans.

(12)	Common Stock

On May 20, 2019, the Company completed a public offering of 4,717,949 shares of its common stock, inclusive of 615,384 shares sold upon full exercise of the underwriters’ option to purchase additional shares of common stock, at a price to the public of $9.75 per share. All shares of common stock were sold by the Company. The total gross proceeds from the offering, before deducting underwriting discounts, commissions and offering expenses, were approximately $46.0 million. After deducting the underwriters’ discount, commissions and other offering expenses, the net proceeds were approximately $42.5 million.

(13)	Net Income Per Share Attributable to DASAN Zhone Solutions, Inc.

Basic net income per share attributable to DASAN Zhone Solutions, Inc. is computed by dividing the net income 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 income per share attributable to DASAN Zhone Solutions, Inc. gives effect to common stock equivalents; however, potential common stock equivalents are excluded if their effect is antidilutive. Potential common stock equivalents are composed of incremental shares of common stock issuable upon the exercise of stock options and the vesting of restricted stock units. In periods when a net loss is reported, all common stock equivalents are excluded from the calculation because they would have an anti-dilutive effect, meaning the loss per share would be reduced. Therefore, in periods when a loss is reported, basic and dilutive loss per share are the same.

The following table is a reconciliation of the numerator and denominator in the basic and diluted net income (loss) per share calculation (in thousands, except per share data) for the three and nine months ended September 30, 2019 and September 30, 2018:

Leases

The Company leases certain properties and buildings (including manufacturing facilities, warehouses, and office spaces) and equipment under various arrangements which provide the right to use the underlying asset and require lease payments for the lease term. The Company’s lease portfolio consists of operating leases which expire at various dates through 2027. At September 30, 2019, the Company had one outstanding finance lease.

The Company determines if an arrangement contains a lease at inception. The Company evaluates each service contract upon inception to determine whether it is, or contains, a lease. Such determination is made by applying judgment in evaluating each service contract within the context of the 5-step decision making process under ASC 842. The key concepts of the 5-step decision making process that the Company evaluated can be summarized as: (1) is there an identified physical asset; (2) does the Company have the right to substantially all the economic benefits from the asset throughout the contract period; (3) does the Company control how and for what purpose the asset is used; (4) does the Company operate the asset; and (5) did the Company design the asset in a way that predetermines how it will be used.

Assets and liabilities related to operating leases are included in the condensed consolidated balance sheet as right-of-use assets from operating leases, operating lease liabilities - current and operating lease liabilities - non-current.

Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Many of the Company’s lease agreements contain renewal options; however, the Company does not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that the Company is reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of the Company’s lease agreements contain rent escalation clauses, rent holidays, capital improvement funding or other lease concessions.

The Company recognizes minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. The Company amortizes this expense over the term of the lease beginning with the date of initial possession, which is the date lessor makes an underlying asset available for use. Variable lease components represent amounts that are not fixed in nature, are not tied to an index or rate, and are recognized as incurred.

In determining its right-of-use assets and lease liabilities, the Company applies a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires the Company to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The Company determines the incremental borrowing rate for each lease based primarily on its lease term and the economic environment of the applicable country or region. When the Company cannot readily determine the discount rate implicit in the lease agreement, the Company utilizes an incremental borrowing rate based on the most recent debt facilities interest rates and applicable to the local geography and with similar term to lease.

For the measurement and classification of its lease agreements, the Company groups lease and non-lease components into a single lease component for all underlying asset classes. Variable lease payments include payments for non-lease components of maintenance costs. The components of lease expense were as follows for the three and nine months ended September 30, 2019:

	Three Months Ended September 30, 2019 (in thousands)		Nine Months Ended September 30, 2019 (in thousands)

The Company is generally responsible for warranty liabilities for a period of two years with respect to major product sales and has, therefore, contracted for surety insurance for a portion of the warranty liabilities.

Legal Proceedings

From time to time, the Company is 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, the Company records an accrual for legal contingencies that it has determined to be probable to the extent that the amount of the loss can be reasonably estimated. The Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on its consolidated financial position, results of operations or cash flows. 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.

(16)	Income Taxes

Income tax expense for the three and nine months ended September 30, 2019 was approximately $0.3 million and $1.1 million, respectively, on pre-tax loss of $3.7 million and $2.0 million, respectively. Income tax expense for the three and nine months ended September 30, 2018 was $0.7 million and $1.1 million, respectively, on pre-tax income of $2.6 million and $4.4 million, respectively.

For the three and nine months ended September 30, 2019 and 2018, the effective income tax rate varied from the United States statutory income tax rate primarily due to valuation allowances in the United States and the mix of earnings generated by the Company’s wholly owned foreign subsidiaries.

The total amount of unrecognized tax benefits, including interest and penalties, at September 30, 2019 was $0.8 million. The amount of tax benefits that would impact the effective income tax rate, if recognized, is $0.1 million. There were no significant changes to unrecognized tax benefits during the three and nine months ended September 30, 2019 and 2018. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

(17)	Enterprise-Wide Information

As of September 30, 2019, we employed over 830 personnel worldwide, of which approximately half are engineers or engaged in research and development.

RECENT DEVELOPMENTS

On July 9, 2019, the Company entered into a lease agreement (the “Lease”) with Family Stations, Inc., a California corporation (“Lessor”). The Lease covers approximately 16,500 square feet of space located at 1350 South Loop Road, Alameda, California (the “Premises”). The Lease provides for a term of 63 months, commencing on November 1, 2019 (or such later date as contemplated by the Lease in the event Lessor is unable to tender possession of the Premises by such date), with a basic monthly rent ranging from $41,273 to $47,846 per month.

On August 26, 2019, Michael Golomb, our Chief Financial Officer, resigned from such position. We have initiated a search for his replacement and Mr. Golomb has agreed to consult with us to provide advice regarding the transition of responsibilities. While the Company is pursuing a permanent replacement for Mr. Golomb, Il Yung Kim, the Company’s President and Chief Executive Officer will serve as interim Chief Financial Officer.

On November 8, 2019, the Company received a waiver from the lenders under the Credit Agreements with respect to the Company’s violation at September 30, 2019 of the maximum leverage ratio financial covenant of the Credit Agreements. As a condition for the issuance of the waiver, the Company voluntarily prepaid $10.0 million of the outstanding term loan and paid a one-time fee of $150,000.

Net Revenue

Net Revenue for the three months ended September 30, 2019 of $71.5 million was slightly lower as compared to $71.9 million for the same period last year. We believe, the slight decrease in net revenue during the period was primarily attributed to softer spending from wireline carriers. For the nine months ended September 30, 2019, net revenue increased by 10% or $21.6 million to $229.3 million from $207.7 million for the same period last year. The increase in net revenue during the period was partly due to the impact of the Keymile Acquisition and increased product and services sales primarily in the Europe, Middle East and Africa (“EMEA”), and Korea regions.

Information about our net revenue for products and services is summarized below (in millions):

	Three Months Ended September 30,										Nine Months Ended September 30,
	2019		2018		Increase/ (Decrease)			% change			2019		2018		Increase/ (Decrease)		% change
Products	$	66.4	$	68.8	$	(2.4	)		(3	)%	$	214.9	$	198.8	$	16.1		8	%
Services		5.1		3.1		2.0			65	%		14.4		8.9		5.5		62	%
Total	$	71.5	$	71.9	$	(0.4	)		(1	)%	$	229.3	$	207.7	$	21.6		10	%

For the three months ended September 30, 2019, product revenue decreased by 3% or $2.4 million to $66.4 million from $68.8 million in the same period last year. The decrease in product revenue during the period was primarily attributed to softer spending from wireline carriers coupled with delayed purchases from one of our major customers in Japan. For the nine months ended September 30, 2019, product revenue increased by 8% or $16.1 million to $214.9 million from $198.8 million in the same period last year. The increase in product revenue during the period was primarily due to an increase in product sales, resulting from the impact of the Keymile Acquisition, as well as our broadened geographical base and product offerings, particularly in the EMEA, and Korea regions.

Service revenue represents revenue from maintenance and other services associated with product shipments. For the three months ended September 30, 2019, service revenue increased by 65% or $2.0 million to $5.1 million from $3.1 million in the same period last year. For the nine months ended September 30, 2019, service revenue increased by 62% or $5.5 million to $14.4 million from $8.9 million in the same period last year. The increase in service revenue was due to the Keymile Acquisition and an increase in the number of products under contract for maintenance and extended warranty.

Information about our net revenue for North America and international markets is summarized below (in millions):

	Three Months Ended September 30,										Nine Months Ended September 30,
	2019		2018		Increase/ (decrease)			% change			2019		2018		Increase/ (decrease)			% change

Total	$	71.5	$	71.9	$	(0.4	)		(1	)%	$	229.3	$	207.7	$	21.6			10	%

From a geographical perspective, the decrease in net revenue for the three months ended September 30, 2019 was attributable to declining revenue in North America and Other Asia Pacific regions, partially offset by increased revenues in the EMEA region due to the Keymile Acquisition. The increase in net revenue for the nine months ended September 30, 2019 was primarily attributable to increased revenues in the EMEA region due to the impact of the Keymile Acquisition, as well as increased revenues in Korea, partially offset by the decline in revenue in North America and Latin America due to changes in the buying patterns of certain customers.

Across international markets, net revenue for the three months ended September 30, 2019 increased 2% or $1.1 million to $60.7 million from $59.6 million for the same period last year, and represented 85% of total net revenue compared with 83% during the same period of 2018. The increase in international net revenue was primarily related to the Keymile Acquisition. International net revenue for the nine months ended September 30, 2019 increased 21% or $34.3 million to $197.3 million from $163.0 million for the same period last year, and represented 86% of total net revenue compared with 78% during the same period of 2018. The increase in international net revenue was partly related to the Keymile Acquisition and increased product sales in the EMEA, and Korea regions during the period.

For the three months ended September 30, 2019, one customer accounted for 11% of net revenue. For the nine months ended September 30, 2019, no single customer accounted for 10% or more of net revenue. For the three and nine months ended September 30, 2018, one customer accounted for 11% of net revenue. However, 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.

Cost of Revenue and Gross Profit

Total cost of revenue increased 2% or $0.8 million to $49.3 million for the three months ended September 30, 2019, compared to $48.5 million for the three months ended September 30, 2018. Total cost of revenue was 69% of net revenue for the three months ended September 30, 2019, compared to 67% for the three months ended September 30, 2018. Total cost of revenue increased 11% or $15.1 million to $154.4 million for the nine months ended September 30, 2019, compared to $139.3 million for the nine months ended September 30, 2018. Total cost of revenue was 68% of net revenue for the nine months ended September 30, 2019, compared to 67% for the nine months ended September 30, 2018. Gross profit percentage remained substantially flat at 33% for the nine months ended September 30, 2019 and 2018. Gross profit percentage for the three months ended September 30, 2019 was slightly lower at 31% as compared to 33% for the three months ended September 30, 2018, mainly due to product mix and foreign currency exchange rate fluctuations.

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 expenses relating to discontinued products and excess or obsolete inventory.

Research and Product Development Expenses

Research and product development expenses increased 14% or $1.2 million to $9.9 million for the three months ended September 30, 2019 compared to $8.7 million for the three months ended September 30, 2018. As a percentage of sales, research and product development expenses were 14% for the three months ended September 30, 2019, compared to 12% for the three months ended September 30, 2018. Research and product development expenses increased 12% or $3.2 million to $29.5 million for the nine months ended September 30, 2019 compared to $26.3 million for the nine months ended September 30, 2018. As a percentage of sales, research and product development expenses were 13% for the nine months ended September 30, 2019 and 2018. The increase in research and product development expenses was primarily due to the Keymile Acquisition. 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. We have grown our research and development capabilities, particularly in software development, by using lower cost centers like Vietnam.

Selling, Marketing, General and Administrative Expenses

Selling, marketing, general and administrative expenses increased 42% or $4.6 million to $15.7 million for the three months ended September 30, 2019, compared to $11.1 million for the three months ended September 30, 2018. As a percentage of sales, selling, marketing, general and administrative expenses were 22% for the three months ended September 30, 2019, compared to 16% for the three months ended September 30, 2018. Selling, marketing, general and administrative expenses increased 30% or $10.5 million to $45.7 million for the nine months ended September 30, 2019, compared to $35.2 million for the nine months ended September 30, 2018. As a percentage of sales, selling, marketing, general and administrative expenses were 20% for the nine months ended September 30, 2019, compared to 17% for the nine months ended September 30, 2018. The increase in selling, marketing, general and administrative expenses was primarily due to the impact of the Keymile Acquisition and growth in business as we continue to expand our presence internationally.

Income Tax Provision

Income tax expense for the three and nine months ended September 30, 2019 was $0.3 million and $1.1 million, respectively, on pre-tax loss of $3.7 million and $2.0 million, respectively. Income tax expense for the three and nine months ended September 30, 2018 was $0.7 million and $1.1 million, respectively, on pre-tax income of $2.6 million and $4.4 million, respectively. For the three and nine months ended September 30, 2019 and September 30, 2018, the effective income tax rate varied from the United States statutory income tax rate primarily due to valuation allowances in the United States and the mix of earnings generated by our wholly owned foreign subsidiaries.

OTHER PERFORMANCE MEASURES

In managing our business and assessing our financial performance, we supplement the information provided by our U.S. GAAP results with adjusted earnings before interest, taxes, depreciation and amortization and the impact of certain other charges or transactions, or Adjusted EBITDA, a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss), as defined by GAAP, before (i) interest expense, net, (ii) provision (benefit) for income taxes, (iii) depreciation and amortization expense, (iv) stock-based compensation expenses, and (v) the impact of material transactions or events that we believe are not indicative of our core operating performance, such as merger and acquisition transaction costs, inventory step-up valuation amortization, bargain purchase gain, gain or (loss) on sale of assets or impairment of fixed assets, any of which may or may not be recurring in nature. 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;

•

Although depreciation and amortization are non-cash expenses, 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;

•

Stock-based 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 U.S. GAAP or as a measure of liquidity. Management understands these limitations and compensates for these limitations by relying primarily on our U.S. GAAP results and using Adjusted EBITDA only as a supplemental measure.

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

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

For a complete description of what we believe to be the critical accounting policies and estimates used in the preparation of our unaudited condensed consolidated financial Statements, refer to Note 1, Organization and Summary of Significant Accounting Policies, in the notes to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2018, as supplemented by Note 1, Organization and Summary of Significant Accounting Policies, in the notes to our unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

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.

The following table summarizes the information regarding our cash and cash equivalents and working capital (in thousands):

Operating Activities

Net cash used in operating activities increased by $6.2 million to $21.9 million for the nine months ended September 30, 2019 from $15.7 million for the nine months ended September 30, 2018 primarily due to the decrease in earnings between the two periods and the net effect of changes in operating assets and liabilities during the period.

Investing Activities

Net cash used in investing activities increased by $5.4 million to $6.2 million for the nine months ended September 30, 2019 from $0.8 million for the nine months ended September 30, 2018. This increase was primarily due to the payment of the purchase price of $11.8 million, net of cash received of $7.1 million, in the Keymile Acquisition.

Financing Activities

Net cash provided by financing activities increased by $31.0 million to $46.2 million for the nine months ended September 30, 2019 from $15.2 million for the nine months ended September 30, 2018. This increase was primarily due to the public stock offering in May 2019 in which we received $42.5 million in net proceeds and the borrowing proceeds received upon entry into the PNC Facility (defined below), partially offset by repayments of short-term and long-term borrowings.

Cash Management

Our primary source of liquidity comes from our cash and cash equivalents, which totaled $47.9 million at September 30, 2019, as well as our PNC Bank Facility, under which we had aggregate revolving line availability of $12.0 million as of September 30, 2019. Our cash and cash equivalents as of September 30, 2019 included $7.4 million in cash balances held by our international subsidiaries.

On February 27, 2019, DZS and ZTI (collectively, the “Borrowers”), and certain direct and indirect subsidiaries of the Borrowers, as guarantors, entered into that certain Revolving Credit, Term Loan, Guaranty and Security Agreement (the “Domestic Credit Agreement”) and that certain Export-Import Revolving Credit, Guaranty and Security Agreement (the “Ex-Im Credit Agreement,” and together with the Domestic Credit Agreement, the “Credit Agreements”), in each case with PNC Bank, National Association (“PNC”) and Citibank, N.A. as lenders, and PNC as agent for the lenders (the “PNC Facility”), which replaced our former senior secured credit facilities with Wells Fargo Bank (the “Former WFB Facility”).

The Credit Agreements provide for a $25.0 million term loan and a $15.0 million revolving line of credit (including subfacilities for Ex-Im transactions, letters of credit and swing loans). The amount we are able to borrow on the revolving line of credit at any time is based on eligible accounts receivable and other conditions, less certain reserves. Borrowings under the PNC Facility bear interest at our option, at either (i) a base rate equal to the highest of the federal funds rate plus 0.50%, PNC’s prime rate, or the daily LIBOR rate plus 1.00%, or (ii) the LIBOR rate for the applicable interest period, subject to a floor of 1.00% (with respect to the term loans only), plus in each case, an applicable margin. The applicable margin for term loans is 5.00% for base rate loans and 6.00% for LIBOR rate loans, and the applicable margin for borrowings under the revolving line of credit is 1.50% for base rate loans and 2.50% for LIBOR rate loans.

We used a portion of the funds borrowed from the term loan under the Credit Agreements to (i) repay $5.0 million in principal amount of existing related-party indebtedness with DNI plus accrued interest, (ii) repay $1.5 million in outstanding borrowings plus accrued interest and fees and cash collateralize $3.6 million in outstanding letters of credit under the Former WFB Facility, and (iii) repay $5.6 million in short-term debt in Korea and Japan. We intend to use the remaining funds for ongoing working capital needs. Obligations under the Credit Agreements are secured by substantially all of the personal property assets of the Borrowers and the subsidiaries that guarantee the Credit Agreements, including their intellectual property.

As of September 30, 2019, we had $23.8 million in outstanding term loan borrowings and no outstanding revolving line of credit borrowings under the Credit Agreements. On July 2, 2019, $4.4 million in outstanding borrowings under the revolving line of credit (which represented all outstanding borrowings under the revolving line of credit) was paid in full.

As of September 30, 2019, the interest rate on the term loan was 8.12%. Deferred financing cost of $1.5 million as of September 30, 2019 has been netted against the aggregate principal amount of the PNC term loan in the unaudited condensed consolidated balance sheet as of September 30, 2019.

Former Wells Fargo Bank Facility

On February 27, 2019, in connection with the entry into the PNC Facility, we repaid $1.5 million in principal amount of outstanding borrowings plus accrued interest and fees under the Former WFB Facility, cash collateralized $3.6 million outstanding letters of credit under the Former WFB Facility and terminated the Former WFB Facility.

Working Capital Loan

On October 1, 2018, as a condition for the Keymile Acquisition, the former stockholder of Keymile extended a €4.0 million ($4.4 million) working capital loan to Keymile. The working capital loan bears interest at a rate of 3.5% per annum and is scheduled for repayment in two equal installments. The first payment of €2 million ($2.2 million) was made in April 2019 and the balance is due in November 2019. As of September 30, 2019, the outstanding balance under this working capital loan was €2.0 million ($2.2 million). Subsequently in November 2019, the Company fully repaid all the outstanding borrowings under this working capital loan.

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 as they mature and are generally secured by a security interest in certain assets of the applicable foreign subsidiaries and supported by guarantees given by DNI or third parties. Payments under such facilities are made in accordance with the given lender’s amortization schedules. As of September 30, 2019 and December 31, 2018, we had an aggregate outstanding balance of $20.6 million and $24.8 million, respectively, under such financing arrangements, and the interest rate per annum applicable to outstanding borrowings under these financing arrangements ranged from 0% to 5.49% as of September 30, 2019.

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. The term loan was scheduled to mature in September 2021 and was pre-payable at any time by us without premium or penalty. The interest rate under this facility was 4.6% per annum. In February 2019, we repaid the term loan in full plus accrued interest in connection with the entry into the PNC Facility, thereby terminating the loan agreement.

In February 2016, DNS borrowed $1.8 million from DNI for capital investment with an interest rate of 4.6% per annum. On February 27, 2019, in connection with the entry into the PNC Facility, the parties amended the terms of this loan to extend the repayment date until May 27, 2022. As of September 30, 2019, the $1.8 million balance of the loan remained outstanding.

On December 27, 2018, we entered into a Loan Agreement with DNI for a $6.0 million term loan with an interest rate of 4.6% per annum. On February 27, 2019, in connection with the entry into the PNC Facility, the parties amended the terms of the term loan to extend the repayment date until May 27, 2022 and to terminate the security interest granted to DNI with respect to such term loan. As of September 30, 2019, the $6.0 million balance of the loan remained outstanding.

On March 27, 2018, Dasan Network Solutions, Inc., a subsidiary of the Company incorporated under the laws of Korea (“DNS Korea”), borrowed KRW6.5 billion ($5.8 million) from DNI. The loan bears interest at a rate of 4.6% and is secured by certain accounts receivable of DNS Korea. On February 27, 2019, in connection with the entry into the PNC Facility, the parties amended the terms of this loan to extend the repayment date until May 27, 2022. As of September 30, 2019, KRW1.5 billion ($1.3 million) remained outstanding.

Interest expense on these related-party borrowings was $0.1 million for each of the three months ended September 30, 2019 and 2018, and $0.3 million for each of the nine months ended September 30, 2019 and 2018.

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 September 30, 2019, two customers represented 17% and 12% of net accounts receivable, respectively, and receivables from customers in countries other than the United States represented 94% of net accounts 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.

Operating Leases

The operating lease amounts shown above represent leases for certain properties and buildings (including manufacturing facilities, warehouses, and office spaces) and equipment under various arrangements which provide the right to use the underlying asset and require lease payments for the lease term. For additional information regarding how leases are reported on our balance sheet, see Note 14 in the notes to our unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Purchase Commitments

The purchase commitments shown above represent non-cancellable inventory purchase commitments as of September 30, 2019.

Short-term Debt

Our short-term debt obligations have been recorded as liabilities on our balance sheet, and as of September 30, 2019 are comprised of $20.6 million in outstanding borrowings under the credit facilities of our foreign subsidiaries, $12.5 million in outstanding borrowings under the Credit Agreements and $2.2 million in outstanding borrowings under a working capital loan from the former stockholder of Keymile. Such amounts represent scheduled principal repayments, but not the associated interest payments which may vary based on changes in market interest rates. At September 30, 2019, the interest rate per annum applicable to outstanding borrowings under the trade facilities of our foreign subsidiaries ranged from 0% to 5.49%, was 8.12% under the PNC term loan, and was 3.5% for the Keymile working capital loan. See above under "Cash Management" for further information about these facilities.

Related-Party Debt

As of September 30, 2019, we had an aggregate of $9.1 million in outstanding borrowings from DNI, which consisted of a $6.0 million unsecured subordinated term loan facility which matures in May 2022, a $1.8 million loan for capital investment which matures in May 2022, and KRW 1.5 billion ($1.3 million) outstanding under a secured loan from DNS Korea which matures in May 2022. All three loans bear interest at a rate of 4.6% per annum.

See “Cash Management” – “Related-Party Debt” above and Note 11 in the notes to our unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information about our related-party debt.

Item 3.

Quantitative and Qualitative Disclosures about Market Risk

Concentration of Credit Risk

We are potentially exposed to concentrations of credit risk, through our cash and cash equivalents, which totaled $47.9 million at September 30, 2019, including $7.4 million held by our international subsidiaries and our accounts and other receivables, net, which totaled $108.9 million at September 30, 2019. Cash and cash equivalents consist of financial deposit and money market accounts that are principally held with various domestic and international financial institutions with high credit standing. We perform ongoing credit evaluations of our customers and generally do not require collateral to secure our receivables. 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 September 30, 2019 and December 31, 2018, receivables from customers in countries other than the United States represented 94% and 88%, 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 September 30, 2019, our outstanding variable-interest debt balance was $44.4 million, which consisted of principal amount of borrowings under the short-term credit facilities of our foreign subsidiaries and term loan borrowings under the Credit Agreements (all of which bear interest at a variable rate). As of September 30, 2019, amounts borrowed under our short-term credit facilities bore interest ranging from 0% to 5.49%, and amounts borrowed under the PNC term loan bore interest at 8.12%. Assuming the outstanding balance on our variable rate debt remains constant over a year, a 1% increase in the interest rate would decrease pre-tax income and cash flow by approximately $0.5 million. In addition, as of September 30, 2019, we had an aggregate of $11.2 million in outstanding borrowings from DNI and Riverside (all of which bear interest at a fixed rate of 4.6% and 3.5%, respectively).

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 Asia, Europe, 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.

We have performed a sensitivity analysis as of September 30, 2019 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 $3.5 million at September 30, 2019. 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 are required to 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 Exchange Act 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 principal executive officer and principal financial officer, as appropriate to allow for timely decisions regarding required disclosures. Our disclosure controls and procedures include those components of our internal control over financial reporting intended to provide reasonable assurance that transactions are recorded as necessary to permit preparation of financials in accordance with U.S. GAAP. 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 Rule 13a-15(b) under the Exchange Act, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of September 30, 2019, the end of the period covered by this Quarterly Report on Form 10-Q. The evaluation was done under the supervision and with the participation of management, including our principal executive officer and principal financial officer. In the course of the evaluation of our disclosure controls and procedures, our principal executive officer and principal financial officer concluded that, because of the unresolved material weaknesses in our internal control over financial reporting as described below, our disclosure controls and procedures were not effective as of September 30, 2019.

Material Weakness in Internal Control Over Financial Reporting

In connection with the Company’s annual evaluation of its internal control over financial reporting conducted in accordance with SEC Rule 13a-15(c), the Company’s management, including our Chief Executive Officer and Chief Financial Officer, identified a material weakness in the Company’s internal control over financial reporting, and as a result thereof, determined that the Company’s internal control over financial reporting was not effective as of December 31, 2018.

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. Following consummation of the Merger with DNS, management identified material weaknesses in our internal control over financial reporting, which continued to exist at December 31, 2018. Specifically, management determined that 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. Additionally, the Company has failed to maintain effective controls over our financial close process. Further, 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 Merger, 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 ended September 30, 2016.

We continue to evaluate and assess the design and operation of our controls and are taking steps to modify processes related to the accounting for significant and unusual transactions as well as enhancing monitoring and oversight controls in the application of accounting guidance related to such transactions. In connection therewith, we have hired and we anticipate that we will hire additional accounting personnel with relevant skills, training and experience, and conduct further training of our 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. Integration activities related to the Keymile Acquisition may lead us to modify certain internal controls in future periods.

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 Quarterly Report on Form 10-Q, 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, 2018, which could materially affect our business, financial condition or future results. Except as provided below, 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, 2018. 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.

DNI owns a significant amount of our outstanding common stock and has the ability to exert significant influence or control over any matters that require stockholder approval, including the election of directors and the approval of certain transactions, and DNI’s interests may conflict with our interests and the interests of other stockholders

As of September 30, 2019, DNI owned approximately 44.4% of the outstanding shares of our common stock, representing a significant amount of the votes entitled to be cast by the holders of our outstanding common stock at a stockholder meeting. Due to its significant ownership percentage of our common stock DNI has the ability to substantially influence or control the outcome of any matter submitted for the vote of our stockholders, including the election of directors and the approval of certain transaction. The interests of DNI may conflict with the interests of our other stockholders or with holders of our indebtedness and may cause us to take actions that our other stockholders or holders of our indebtedness do not view as beneficial.

In addition, DNI’s large concentration of stock ownership may make it more difficult for a third party to acquire us or discourage a third party from seeking to acquire us. A potential third party acquirer would be required to negotiate any such transaction with DNI, and the interests of DNI with respect to such transaction may be different from the interests of our other stockholders or with holders of our indebtedness.

Prior to May 20, 2019, DNI owned in excess of 50% of the outstanding shares of our common stock, which allowed us to elect to be treated as a “controlled company” under Nasdaq Marketplace Rules. As a “controlled company,” we were exempt from certain corporate governance requirements under Nasdaq Marketplace Rules, including the requirement that we have a majority of independent directors on the Board of Directors and requirements with respect to compensation and nominating and corporate governance committees. Following the loss of “controlled company” status, we are required to phase in compliance with the Nasdaq corporate governance requirements over a one-year period.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders (except for causes of action arising under the federal securities laws), which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated bylaws (our “Bylaws”) provide that the Court of Chancery of the State of Delaware is the sole and exclusive forum for:

•

any derivative action or proceeding brought on behalf of the Company;

•

any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of the Company to the Company or the Company’s stockholders;

•

any action asserting a claim against the Company arising pursuant to any provision of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or the Bylaws; and

•

any action asserting a claim against the Corporation governed by the internal affairs doctrine, in each such case subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein;

provided, that with respect to any derivative action or proceeding brought on our behalf to enforce any liability or duty created by the Exchange Act or the rules and regulations thereunder, the exclusive forum will be the federal district courts of the United States. The exclusive forum provision in our Bylaws does not apply to resolving any complaint asserting a cause of action arising under the Securities Act.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find the exclusive forum provision in our Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business. For example, the Court of Chancery of the State of Delaware recently determined that the exclusive forum provision of federal district courts of the United States for resolving any complaint asserting a cause of action arising under the Securities Act is not enforceable. However, this decision may be reviewed and ultimately overturned by the Delaware Supreme Court.

Increased tariffs on products and goods that we purchase from off-shore sources (particularly Chinese sources) and changes in international trade policies and relations could have an adverse effect on our customers and operating results.

The United States has recently imposed tariffs on a wide-range of products and goods manufactured in China that are directly or indirectly imported into the United States, and it has announced plans to impose additional tariffs on products and goods manufactured in China. In response, various countries and economic regions have announced plans or intentions to impose retaliatory tariffs on a wide-range of products they import from the United States. These newly imposed, announced and threatened U.S. tariffs and retaliatory tariffs could have the effect of increasing the cost of materials we use to manufacture certain products, which could result in lower margins. The tariffs could also result in disruptions to our supply chain, as suppliers struggle to fill orders from companies trying to purchase goods in bulk ahead of announced tariffs. Although we currently believe that the incremental costs to us of these tariffs will be immaterial, if the amount of these tariffs increases or if the tariffs apply to additional categories of components used in our manufacturing activities, and if we are unable to pass on the costs of tariffs to our customers, our operating results would be harmed. In addition, changes in the political environment, governmental policies, international trade policies and relations, or U.S.-China relations could result in revisions to laws or regulations or their interpretation and enforcement, trade sanctions, or retaliatory actions by China in response to U.S. actions, which could have an adverse effect on our customers, business plans and operating results.

Until the Company hires a permanent Chief Financial Officer, our Chief Executive Officer will also be serving as our interim Chief Financial Officer, which could have an adverse impact on our business.

Following the formerly-announced resignation of our former Chief Financial Officer, Michael Golomb, Mr. Il Yung Kim, the Chief Executive Officer of the Company, was appointed to serve as our interim Chief Financial Officer. As a result of this change, Mr. Il Yung Kim has taken on substantially more responsibility for the management of our business and of our financial reporting, which has resulted in greater workload demands and could divert his attention away from certain key areas of our business. Mr. Kim’s serving in a temporary dual capacity of Chief Executive Officer and interim Chief Financial Officer of the Company may have a disruptive impact on our ability to implement our strategy and could adversely affect our business, internal controls, financial condition and results of operations. Until we find and integrate a permanent Chief Financial Officer, we may be unable to successfully manage and grow our business, and our results of operations, internal controls and financial condition could suffer as a result. Leadership transitions can be inherently difficult to manage and may cause uncertainty and decreased productivity among our employees and increase the likelihood of turnover, which could result in significant disruptions to our operations. We could be adversely affected if we fail to adequately plan for the succession of members of our senior management team should we have additional departures. Finally, we continue to execute a number of significant business initiatives. Successfully managing these initiatives, including retention of key employees, is critical to our business success.

Item 5.

Other Information

As noted above, at September 30, 2019, the Company was not in compliance with the maximum leverage ratio financial covenant in the Credit Agreements, which represents an event of default thereunder. On November 8, 2019, the Company obtained a waiver of the foregoing event of default from the lenders under the Credit Agreements (the “Waiver”). As a condition for the issuance of the Waiver, the Company voluntarily prepaid $10.0 million of the outstanding term loan and paid a one-time fee of $150,000. The foregoing description of the Waiver is qualified in its entirety by reference to the Waiver, a copy of which is filed as Exhibit 10.3 hereto.
