NeoPhotonics Corporation Notes to Condensed Consolidated Financial Statements

Note 1. Basis of presentation and significant accounting policies
Basis of Presentation and Consolidation
The condensed consolidated financial statements of NeoPhotonics Corporation (“NeoPhotonics” or the “Company”) as of March 31, 2021 and for the three months ended March 31, 2021 and 2020, have been prepared in accordance with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, the Company has omitted certain information and notes normally provided in the Company’s annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, consisting only of normal recurring items, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the interim periods. These condensed consolidated financial statements do not include all disclosures required by U.S. generally accepted accounting principles (“U.S. GAAP”) and should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results expected for the entire fiscal year. All intercompany accounts and transactions have been eliminated.
Certain Significant Risks and Uncertainties
The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, any of the following areas could have a negative effect on the Company in terms of its future financial position, results of operations or cash flows: the general state of the U.S., China and world economies; the highly cyclical nature of the industries the Company serves; successful and timely completion of product design efforts; the ability of the Company to sell its new products into new market segments; trade restrictions by the United States against the Company's customers in China, as well as potential retaliatory trade actions taken by China; the loss of any of its larger customers; restrictions on the Company's ability to sell to foreign customers due to additional U.S. or new China trade laws, regulations and requirements; disruptions of the supply chain of components needed for its products; ability to obtain additional financing; inability to meet certain debt covenants; fundamental changes in the technology underlying the Company’s products; the hiring, training and retention of key employees; and new product design introductions by competitors. The inputs into the Company’s judgments and estimates consider the economic implications of the Covid-19 pandemic as the Company knows them, on its critical and significant accounting estimates. The extent to which the Covid-19 pandemic may impact its business will depend on future developments, which are highly uncertain, such as the duration of the outbreak, travel restrictions, governmental mandates issued to mitigate the spread of the disease, business closures, economic disruptions, and the effectiveness of actions taken to contain and treat the virus. Accordingly, future adverse developments with respect to the Covid-19 pandemic may have a negative impact on its sales, supply chain and results of operations. The inputs into the Company's judgments and estimates also consider the Department of Commerce Entities List restrictions on Huawei Technologies effective September 2020 for the Company and expected loss of business from Huawei Technologies. See also Note 7.
In the three months ended March 31, 2021, four customers were each greater than 10% and the Company’s total revenue and the Company's top five customers represented approximately 80% of the Company’s total revenue. In the three months ended March 31, 2020, two customers were greater than 10% of the Company's total revenue. Huawei accounted for approximately 52% of the Company's total revenue, one other customer was greater than 10% and the Company’s top five customers represented approximately 85% of the Company’s total revenue.
As of March 31, 2021, four customers accounted for a total of 72% of the Company’s total accounts receivable. As of December 31, 2020, three customers accounted for a total of 65% of the Company’s total accounts receivable.
Use of Estimates
The preparation of financial statements in accordance 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 financial statements and the reported revenue and expenses during the reporting period. Significant estimates made by management include: the useful lives and recoverability of long-lived assets; valuation allowances for deferred tax assets; valuation of excess and obsolete inventories; warranty reserves; litigation accrual and recognition of stock-based compensation, among others. Actual results could differ from these estimates.
Long-lived Assets
The Company assesses the impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss would be recognized when the sum of the future net cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance and may differ from actual cash flows.

Due to the additional restrictions imposed by the U.S. Bureau of Industry and Security ("BIS"), an agency of the U.S. Department of Commerce, which became effective in September 2020, and the expected loss of business from Huawei, the

Table of Contents
Notes to Condensed Consolidated Financial Statements (Continued)
Company performed a recoverability test in the third and fourth quarters of 2020 and determined there was no impairment of long-lived assets.
The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, other current liabilities and operating lease liabilities on the Company's condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, current portion of long-term debt and long-term debt, net of current portion on the condensed consolidated balance sheets.
Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, the Company uses an estimate of its incremental borrowing rate based on observed market data and other information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less. The Company does not separate lease and non-lease components but rather account for each separate component as a single lease component for all underlying classes of assets. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. Lease expense for minimum operating lease payments is recognized on a straight-line basis over the lease term.
Accounting Pronouncements Recently Adopted
In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes. This guidance became effective for fiscal years beginning after December 15, 2020. The Company adopted this ASU in the first quarter of 2021 and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Recent Accounting Pronouncements Not Yet Effective 
In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends existing guidance on the impairment of financial assets and adds an impairment model that is based on expected losses rather than incurred losses and requires an entity to recognize as an allowance its estimate of expected credit losses for its financial assets. An entity will apply this guidance through a cumulative-effect adjustment to retained earnings upon adoption (a modified-retrospective approach) while a prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. In November 2019, the FASB issued ASU 2019-10, according to which, the new standard is effective for smaller reporting companies (“SRC”) as defined by the SEC, for fiscal years beginning after December 15, 2022 including interim periods within those fiscal years. The Company is in the process of evaluating the impact and timing of the adoption on its consolidated financial statements and related disclosures.
Note 2. Revenue
Product revenue
The Company develops, manufactures and sells lasers and other high-speed optoelectronic products that transmit, receive, modify and switch high speed digital optical signals for communications networks. Revenue is derived primarily from the sale of optoelectronic laser, component and module hardware products. The Company sells its products worldwide, primarily to leading network equipment manufacturers.
Revenue recognition
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company generally bears all costs, risk of loss or damage and retains title to the goods up to the point of transfer of control of promised products to customer. Revenue related to the sale of consignment inventories at customer vendor managed locations is not recognized until the products are pulled from consignment inventories by customers. In instances where acceptance of the product or solutions is specified by the customer, revenue is deferred until such required acceptance criteria have been met. Shipping and handling costs are included in the cost of goods sold. The Company presents revenue net of sales taxes and any similar assessments.
Nature of products
Revenue from the sale of hardware products is recognized upon transfer of control to the customer. The performance obligation for the sale of hardware products is satisfied at a point in time. The Company has aligned its products in two groups - High Speed Products and Network Products and Solutions. The following presents revenue by product group (in thousands):

Note 7. Restructuring Charges
Restructuring charges
On August 17, 2020, BIS increased restrictions on Huawei and its affiliates on the Entity List related to items produced domestically and abroad that use U.S. technology or software and imposed additional requirements for items subject to its export control authority. The Company announced on October 5, 2020, that it will manage the business without relying on and will not plan on future revenue contributions from Huawei. As a result, the Company initiated certain restructuring actions to reduce operating expenses and manufacturing costs while maintaining the Company's focus on its core capabilities, including its lasers, coherent components and solutions for data center interconnect and high speed communications networks. Under the restructuring actions, the Company estimates it will incur severance and related charges of approximately $1.1 million and is expected to be completed by the third quarter of 2021.

Notes payable and short-term borrowing 
The Company regularly issues notes payable to its suppliers in China. These notes are supported by non-interest bearing bank acceptance drafts issued under the Company’s existing line of credit facilities and are due three to six months after issuance. As a condition of the notes payable arrangements, the Company is required to keep a compensating balance at the issuing banks that is a percentage of the total notes payable balance until the amounts are settled. As of March 31, 2021, the Company’s subsidiary in China had two line of credit facilities with the following banking institutions:
Under the first line of credit facility with Shanghai Pudong Development Bank, the Company can borrow up to RMB 120.0 million ($18.3 million) for short-term loans at varying interest rates, or up to approximately RMB 240.0 million ($36.6 million) for bank acceptance drafts (with up to 50% compensating balance requirement). This line of credit facility expires in November 2021.
Under the second line of credit facility with Shanghai Pudong Development Bank, which expires in November 2021, the Company can borrow up to RMB 30.0 million ($4.6 million) for short-term loans at varying interest rates,

or up to approximately RMB 60.0 million ($9.2 million) for bank acceptance drafts (with up to 50% compensating balance requirement).
Under these line of credit facilities, the non-interest bearing bank acceptance drafts issued in connection with the Company’s notes payable to its suppliers in China, had no outstanding balance at March 31, 2021 and December 31, 2020.
As of March 31, 2021 and December 31, 2020, there were no non-interest bearing bank acceptance drafts issued in connection with our notes payable to our suppliers in China under these line of credit facilities. There were no compensating balances relating to these credit facilities as of March 31, 2021 and December 31, 2020, respectively. Compensating balances are classified as restricted cash on the Company’s condensed consolidated balance sheets.
Credit facilities
In September 2017, the Company entered into a revolving line of credit agreement with Wells Fargo Bank, National Association ("Wells Fargo") as the administrative agent for a lender group (the "Wells Fargo Credit Facility" or "Credit Facility").
The Wells Fargo Credit Facility provides for borrowings equal to the lower of (a) a maximum revolver amount of $50.0 million, or (b) an amount equal to 80% - 85% of eligible accounts receivable plus 100% of qualified cash balances up to $15.0 million, less certain discretionary adjustments ("Borrowing Base"). The maximum revolver amount may be increased by up to $25.0 million, subject to certain conditions.
The Credit Facility matures on June 30, 2022 and borrowings bear interest at an interest rate option of either (a) the LIBOR rate, plus an applicable margin ranging from 1.50% to 1.75% per annum, or (b) the prime lending rate, plus an applicable margin ranging from 0.50% to 0.75% per annum. The Company is also required to pay a commitment fee equal to 0.25% of the unused portion of the Credit Facility.
The Credit Facility agreement ("Agreement") requires prepayment of the borrowings to the extent the outstanding balance is greater than the lesser of (a) the most recently calculated Borrowing Base, or (b) the maximum revolver amount. The Company is required to maintain a combination of certain defined cash balances and unused borrowing capacity under the Credit Facility of at least $20.0 million, of which at least $5.0 million shall include unused borrowing capacity. The Agreement also restricts the Company's ability to dispose of assets, to permit change in control, merge or consolidate, make acquisitions, incur indebtedness, grant liens, make investments and make certain restricted payments. Borrowings under the Credit Facility are collateralized by substantially all of the Company's assets.
On June 14, 2019, the Company entered into a First Amendment to the Credit Facility (the "Amended Credit Facility"). The Amendment removes Huawei from the list of “Eligible Accounts” as a basis for the Company’s borrowing while Huawei is on the "Entity List" published by BIS. During the period of time while Huawei remains on the Entity List, the concentration limits of certain other customers are increased to partially offset the removal of Huawei. Additionally, until Huawei is no longer on the Entity List, the Company is required to maintain a temporary combination of certain defined unrestricted cash and unused borrowing capacity under the Credit Facility of at least $30.0 million in the U.S. and $40.0 million world-wide, of which at least $5.0 million shall include unused borrowing capacity. In May 2020, Fiberhome Technologies Group and certain affiliates ("Fiberhome") was added to the BIS Entity List and i
