NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1.   Description of Business

Business Overview

Applied Optoelectronics, Inc. (“AOI” or the “Company”) is a Delaware corporation. The Company is a leading, vertically integrated provider of fiber-optic networking products, primarily for four networking end-markets: internet data center, cable television, telecommunications and fiber-to-the-home. The Company designs and manufactures a wide range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment.

The Company has manufacturing and research and development facilities located in the U.S., Taiwan and China. In the U.S., at its corporate headquarters and manufacturing facilities in Sugar Land, Texas, the Company primarily manufactures lasers and laser components and performs research and development activities for laser component and optical module products. In addition, the Company also has a research and development facility in Duluth, Georgia. The Company operates in Taipei, Taiwan and Ningbo, China through its wholly-owned subsidiary Prime World International Holdings, Ltd. (“Prime World”, incorporated in the British Virgin Islands). Prime World operates a branch in Taipei, Taiwan, which primarily manufactures transceivers and performs research and development activities for the transceiver products. Prime World is also the parent of Global Technology, Inc. (“Global”, incorporated in the People’s Republic of China). Through Global, the Company primarily manufactures certain of its data center transceiver products, including subassemblies, as well as Cable TV Broadband (“CATV”) systems and equipment, and performs research and development activities for the CATV products.

Interim Financial Statements

The unaudited condensed consolidated financial statements of the Company as of June 30, 2019 and December 31, 2018 and for the three and six months ended June 30, 2019 and June 30, 2018, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim information and with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X 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 required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2018. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for doubtful accounts, inventory reserve, product warranty costs, share-based compensation expense, estimated useful lives of property and equipment, and taxes.

Note 2.   Significant Accounting Policies

There have been no changes in the Company’s significant accounting policies for the three and six months ended June 30, 2019, as compared to the significant accounting policies described in its 2018 Annual Report, except as described below.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted in 2019 

On February 25, 2016, the FASB released Accounting Standards Update (ASU) No. 2016-02, Leases, to complete its project to overhaul lease accounting. The ASU codifies ASC 842, Leases, which will replace the guidance in ASC 840. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this ASU on January 1, 2019 without any impact to beginning retained earnings. Upon adoption of the new lease standard, the Company elected the package of practical expedients which allowed it to carry forward the historical lease classification on existing leases at adoption. In addition, the Company elected the short-term lease recognition exemption for all leases that qualify. The Company also elected the practical expedient to not separate lease and non-lease components for all of its leases. The Company has implemented internal controls to enable the presentation of financial information on adoption. The standard has a material impact on the Company’s consolidated balance sheet, but did not have an impact in its consolidated income statements. The most significant effects of adopting the new standard relate to the recognition of new ROU assets and lease liabilities on its balance sheet for its Taiwan branch. See Note 4, "Operating Leases" for additional information on the required disclosures related to the impact of adopting this standard.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The Company adopted this ASU on January 1, 2019 with no impact on its consolidated financial statements.

Recent Accounting Pronouncements Yet to be Adopted

In June 2016, the FASB issued ASU 2016-13 Financial Instruments - Credit Losses, Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Based on the composition of the Company’s investment portfolio, current market conditions, and historical credit loss activity, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial statements.

Note 3. Revenue Recognition

The adoption of Topic 606 represents a change in accounting principle that will provide financial statement readers with enhanced revenue recognition disclosures. In accordance with Topic 606, revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Certain customers may receive cash and/or non-cash incentives, which are accounted for as variable consideration. To achieve this core principle, the Company applies the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when or as the Company satisfies a performance obligation. The Company generally satisfies performance obligations at a point in time. Revenue is recognized based on the transaction price at the time the related performance obligation is satisfied by transferring a promised product or service to a customer.

Disaggregation of Revenue

Revenue is classified based on the location of where the product is manufactured. For additional information on the disaggregated revenues by geographical region, see Note 17, "Geographic Information.”

Note 4. Operating Leases

The Company leases space under non-cancelable operating leases for manufacturing facilities, research and development offices and certain storage facilities and apartments. These leases do not contain contingent rent provisions. The Company also leases certain machinery, office equipment and a vehicle under operating leases. Many of its leases include both lease (e.g. fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g. common-area or other maintenance costs) which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Several of the leases include one or more options to renew which have been assessed and either includes or excludes from the calculation of the lease liability of the ROU asset based on management’s intentions and individual fact patterns. Several warehouses and apartments have non-cancelable lease terms of less than one-year and therefore, the Company has elected the practical expedient to exclude these short-term leases from its ROU asset and lease liabilities.

As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Based on the applicable lease terms and current economic environment, the Company applies a location approach for determining the incremental borrowing rate.

Note 6.   Earnings Per Share

Basic net income (loss) per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units and senior convertible notes outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and diluted earnings per share are the same.

Global’s obligations under the SPD Credit Line will be secured by real property owned by Global and mortgaged to the Bank under the terms of the Security Agreement. The agreements for the SPD Credit Line and the Security Agreement also contain rights and obligations, representations and warranties, and events of default applicable to the Company that are customary for agreements of this type.

Note 12. Convertible Senior Notes

On March 5, 2019, the Company issued $80.5 million of 5% convertible senior notes due 2024 (the “Notes”). The Notes were issued pursuant to an indenture, dated as of March 5, 2019 (the “Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee, paying agent, and conversion agent (the “Trustee”). The Notes bear interest at a rate of 5.00% per year, payable in cash semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2019. The Notes will mature on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms.

The sale of the Notes generated net proceeds of $76.4 million, after deducting the Initial Purchasers’ discounts and offering expenses payable by the Company. The Company used approximately $37.8 million of the net proceeds from the offering to fully repay the CapEx Loan and Term Loan with BB&T and the remainder will be used for general corporate purposes.

The following table presents the carrying value of the Notes for the periods indicated (in thousands):

	June 30,		December 31,
	2019		2018
Principal	$	80,500	$	—
Unamortized debt issuance costs		(3,870)		—
Net carrying amount	$	76,630	$	—

The Notes are convertible at the option of holders of the Notes at any time until the close of business on the scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the Notes will receive shares of the Company’s common stock, together, if applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The initial conversion rate is 56.9801 shares of the Company’s common stock per $1,000 principal amount of Notes (representing an initial conversion price of approximately $17.55 per share of common stock, which represents an initial conversion premium of approximately 30% above the closing price of $13.50 per share of the

19

Company’s common stock on February 28, 2019), subject to customary adjustments. If a make-whole fundamental change (as defined in the Indenture) occurs, and in connection with certain other conversions before March 15, 2022, the Company will in certain circumstances increase the conversion rate for a specified period of time.

Initially there are no guarantors of the Notes, but the Notes will be fully and unconditionally guaranteed, on a senior, unsecured basis by certain of the Company’s future domestic subsidiaries.  The Notes are the Company’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.  The Note Guarantee (as defined in the Indenture) of each future guarantor, if any, will be such guarantor’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to such future guarantor’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to such future guarantor’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.

Holders may require the Company to repurchase their Notes upon the occurrence of a fundamental change (as defined in the Indenture) at a cash purchase price equal to the principal amount thereof plus accrued and unpaid interest, if any.

The Company may not redeem the Notes prior to March 15, 2022.  On or after March 15, 2022, the Company may redeem for cash all or part of the Notes if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such redemption notice.  The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.  In addition, calling any Note for redemption will constitute a “make-whole fundamental change” with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption.

The Indenture contains covenants that limit the Company’s ability and the ability of our subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue disqualified stock; and (ii) create or incur liens.

The Company incurred approximately $4.1 million in transaction costs in connection with the issuance of the Notes. These costs were recognized as a reduction of the carrying amount of the Notes utilizing the effective interest method and are being amortized over the term of the notes.

Note 16.  Income Taxes

The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. The Company’s quarterly tax provision, and its quarterly estimate of its annual effective tax rate, are subject to significant variation due to several factors, including variability in accurately predicting its pre-tax income and loss and the mix of jurisdictions to which they relate, tax law developments and relative changes in permanent tax benefits or expenses.

The Company’s effective tax rate for the three months ended June 30, 2019 and 2018 was (22.0%) and 22.2%, respectively. For the three months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the three months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. global intangible low-taxed income ("GILTI").

The Company’s effective tax rate for the six months ended June 30, 2019 and 2018 was (20.6%) and 11.4% respectively. For the six months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the six months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. GILTI.

As of June 30, 2019, the Company has accumulated undistributed earnings generated by its foreign subsidiaries of approximately $23 million. Because $23 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the Tax Cut of Jobs Act of 2017 (the “Tax Act”), any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of its foreign investments would generally be limited to foreign and state taxes. The Company intends, however, to indefinitely reinvest these earnings and expects future U.S. cash generation to be sufficient to meet future U.S. cash needs.

Note 17.  Geographic Information

The Company operates in one reportable segment. The Company’s Chief Executive Officer, who is considered to be the chief operating decision maker, manages the Company’s operations as a whole and reviews financial information presented on a consolidated basis, accompanied by information about product revenue, for purposes of evaluating financial performance and allocating resources.

The following tables set forth the Company’s revenue and asset information by geographic region. Revenue is classified based on the location of where the product is manufactured. Long-lived assets in the tables below comprise only property, plant, equipment and intangible assets (in thousands):

Litigation

Overview

From time to time, the Company may be subject to legal proceedings and litigation arising in the ordinary course of business, including, but not limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. The Company records a loss provision when it believes it is both probable that a liability has been incurred and the amount can be reasonably estimated. Unless otherwise disclosed, the Company is unable to estimate the possible loss or range of loss for the legal proceeding described below.

Except for the lawsuits described below, the Company believes that there are no claims or actions pending or threatened against it, the ultimate disposition of which would have a material adverse effect on it.

Class Action and Shareholder Derivative Litigation

On August 5, 2017, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against the Company and two of its officers in Mona Abouzied v. Applied Optoelectronics, Inc., Chih-Hsiang (Thompson) Lin, and Stefan J. Murry, et al., Case No. 4:17-cv-02399. The complaint in this matter seeks class action status on behalf of the Company’s shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, its chief executive officer, and its chief financial officer, arising out of its announcement on August 3, 2017 that “we see softer than expected demand for our 40G solutions with one of our large customers that will offset the sequential growth and increased demand we expect in 100G.” A second, related action was filed by Plaintiff Chad Ludwig on August 16, 2017 (Case No. 4:17-cv-02512) in the Southern District of Texas. The two cases were consolidated before Judge Vanessa D. Gilmore. On January 22, 2018, the court appointed Lawrence Rougier as Lead Plaintiff and Levi & Korinsky LLP as Lead Counsel. Lead Plaintiff filed an amended consolidated class action complaint on March 6, 2018. The amended complaint requests unspecified damages and other relief. The Company filed a motion to dismiss on April 4, 2018, which was denied on March 28, 2019.  The Company disputes the allegations, and intends to continue to vigorously defend against these claims.  On May 15, 2019, Lead Plaintiff filed a motion for leave to amend the consolidated class action complaint for the purpose of adding named Plaintiffs Richard Hamilton, Kenneth X. Luthy, Roy H. Cetlin, and John Kugel (together with Lead Plaintiff Lawrence Rougier, “Plaintiffs”) to the case. The court granted the motion on May 16, 2019. The substantive allegations in the Plaintiffs’ operative second amended consolidated class action complaint remain unchanged. On May 28, 2019, Plaintiffs filed a motion seeking to certify the case as a class action pursuant to Federal Rule of Civil Procedure 23 and seeking appointment of Plaintiffs as class representatives and Levi & Korsinsky as class counsel. On July 12, 2019, the Company filed a response in opposition to the motion for class certification. The deadline for Plaintiffs’ reply brief is August 26, 2019. The case is currently in the early stages of discovery, and fact discovery is scheduled to be completed by June 1, 2020..  At this early stage, we are not yet able to determine the likelihood of loss, if any, arising from this matter.

24

On August 7, 2018, Plaintiff Lei Jin filed a purported derivative action on behalf of nominal defendant Applied Optoelectronics, Inc. in the U.S. District Court for the Southern District of Texas against the Company’s chief executive officer, chief financial officer and board of directors (Case No. 4:18-cv-02713).  This case was consolidated with a later filed derivative lawsuit filed by Plaintiff Yiu Kwong Ng in the U.S. District Court for the Southern District of Texas (Case No. 4:18-cv-4751). The allegations in the consolidated derivative complaints are substantially similar to those underlying the Abouzied securities class action and the Taneja securities class action discussed below. The consolidated derivative action is stayed pending a ruling on defendants’ forthcoming motion to dismiss in the Taneja securities class action.

On October 1, 2018, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against the Company and two of its officers in Gaurav Taneja v. Applied Optoelectronics, Inc., Thompson Lin, and Stefan Murry, Case No. 4:18-cv-03544. The complaint in this matter seeks class action status on behalf of the Company’s shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, its chief executive officer, and its chief financial officer, arising out of its announcement on September 28, 2018 that it was revising its third quarter revenue guidance due to “an issue with a small percentage of 25G lasers within a specific customer environment.” This case was consolidated with two identical cases styled Davin Pokoik v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry, Case No. 4:18-cv-3722 and Stephen McGrath v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry.  Mark Naglich was appointed as Lead Plaintiff on the consolidated matter on January 4, 2019.  Lead Plaintiff filed an amended consolidated complaint on March 5, 2019, and the Company filed a motion to dismiss the amended consolidated complaint on May 6, 2019. On July 5, 2019, Plaintiff filed a response in opposition to the motion to dismiss. The deadline for the Company’s reply brief in support of the motion to dismiss is August 5, 2019. The Company disputes the allegations and intends to vigorously contest the matter.

Books and Records Request

On April 10, 2019, stockholder David Bono filed a complaint in the Delaware Court of Chancery against the Company seeking to inspect certain corporate books and records pursuant to Section 220 of the Delaware General Corporation Law.  The lawsuit is styled David Bono v. Applied Optoelectronics, Inc., Case No. 2019-0275 (Del. Ch. 2019).  The complaint does not seek damages but seeks the plaintiff’s costs and expenses, including attorneys’ fees, as well as the requested books and records.  On July 5, 2019, by agreement of the parties, the Vice Chancellor issued an order staying the case to allow the parties to seek resolution of the dispute outside of litigation. A joint status report is due to the Court by September 3, 2019.

Note 19.  Subsequent Events

The Company has evaluated subsequent events through the date the financial statements were available to be issued.

On July 23, 2019, Prime World entered into a one-year revolving credit facility totaling 100,000,000 NTD, or approximately $3.3 million, (the “NT$100M Credit Line”) and 1,000,000 USD (the “US$1M Credit Line”) with Taishin International Bank in Taiwan (“Taishin”). Borrowing under the NT$100M Credit Line will be used for short-term working capital; the borrowing under the US$1M Credit Line will be strictly used for spot transactions in the foreign exchange market. The NT$100M Credit Line and US$1M Credit Line are collectively referred to as the “Credit Facility”. Prime World may draw upon the Credit Facility from July 23, 2019 through July 31, 2020. The term of each draw shall be either 90 or 120 days. Borrowings under the NT$100M Credit Line will bear interest at a rate of 2.25% for 90 day draws and 2.2% for 120 day draws; borrowings under the US$1M Credit Line will bear interest equal to the Taishin’s foreign exchange rate effective on the day of the applicable draw. At the end of the draw term Prime World will make payment for all principal and accrued interest. Prime World’s obligations under the Credit Facility will be secured by a promissory note executed between Prime World and Taishin. The agreements for the Credit Facility contain representations and warranties, and events of default applicable to Prime World that are customary for agreements of this type.

Overview

We are a leading, vertically integrated provider of fiber-optic networking products. We target four networking end-markets: internet data centers, CATV, telecom and FTTH. We design and manufacture a range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment. In designing products for our customers, we begin with the fundamental building blocks of lasers and laser components. From these foundational products, we design and manufacture a wide range of products to meet our customers’ needs and specifications, and such products differ from each other by their end market, intended use and level of integration. We are primarily focused on the higher-performance segments within the internet data center, CATV, telecom and FTTH markets which increasingly demand faster connectivity and innovation. Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and control over product quality and manufacturing costs.

The four end markets we target are all driven by significant bandwidth demand fueled by the growth of network-connected devices, video traffic, cloud computing and online social networking. Within the internet data center market, we benefit from the increasing use of higher-capacity optical networking technology as a replacement for copper cables, particularly as speeds reach 10 Gbps and above, as well as the movement to open internet data center architectures and the increasing use of in-house equipment design among leading internet companies. Within the CATV market, we benefit from a number of ongoing trends including the global build-out of CATV infrastructure, the move to higher bandwidth networks among CATV service providers and the outsourcing of system design among CATV networking equipment companies. In the FTTH market, we benefit from continuing PON deployments and system upgrades among telecommunication service providers. In the telecom market, we benefit from deployment of new high-speed fiber-optic networks by telecom network operators.

Our vertically integrated manufacturing model provides us several advantages, including rapid product development, fast response times to customer requests and control over product quality and manufacturing costs. We

design, manufacture and integrate our own analog and digital lasers using a proprietary Molecular Beam Epitaxy, or MBE, and Metal Organic Chemical Vapor Deposition (MOCVD) fabrication process, which we believe is unique in our industry. We manufacture the majority of the laser chips and optical components that are used in our products. The lasers we manufacture are proven to be reliable over time and highly tolerant of changes in temperature and humidity, making them well-suited to the CATV and FTTH markets where networking equipment is often installed outdoors.

We have three manufacturing sites: Sugar Land, Texas, Ningbo, China and Taipei, Taiwan. Our research and development functions are generally partnered with our manufacturing locations, and we have an additional research and development facility in Duluth, Georgia. In our Sugar Land facility, we manufacture laser chips (utilizing our MBE and MOCVD processes), subassemblies and components. The subassemblies are used in the manufacture of components by our other manufacturing facilities or sold to third parties as modules. We manufacture our laser chips only within our Sugar Land facility, where our laser design team is located. In our Taiwan location, we manufacture optical components, such as our butterfly lasers, which incorporate laser chips, subassemblies and components manufactured within our Sugar Land facility. In addition, in our Taiwan location, we manufacture transceivers for the internet data center, telecom, FTTH and other markets. In our China facility, we take advantage of lower labor costs and manufacture certain more labor intensive components and optical equipment systems, such as optical subassemblies and transceivers for the internet data center market, CATV transmitters (at the headend) and CATV outdoor equipment (at the node). Each manufacturing facility conducts testing on the components, modules or subsystems it manufactures and each facility is certified to ISO 9001:2015. Our facilities in Ningbo, China, Taipei, Taiwan, and Sugar Land, Texas are all certified to ISO 14001:2015.

Our business depends on winning competitive bid selection processes to develop components, systems and equipment for use in our customers’ products. These selection processes are typically lengthy, and as a result our sales cycles will vary based on the level of customization required, market served, whether the design win is with an existing or new customer and whether our solution being designed in our customers’ product is our first generation or subsequent generation product. We do not have any long-term purchase commitments (in excess of one year) with any of our customers, most of whom purchase our products on a purchase order basis, however, once one of our solutions is incorporated into a customer’s design, we believe that our solution is likely to continue to be purchased for that design throughout that product’s life cycle because of the time and expense associated with redesigning the product or substituting an alternative solution.

Our principal executive offices are located at 13139 Jess Pirtle Blvd., Sugar Land, TX 77478, and our telephone number is (281) 295-1800.

Comparison of Financial Results

Revenue

We generate revenue through the sale of our products to equipment providers and network operators for the internet data center, CATV, telecom and FTTH markets. We derive a significant portion of our revenue from our top ten customers, and we anticipate that we will continue to do so for the foreseeable future. The following charts provide the revenue contribution from each of the markets we served for the three and six months ended June 30, 2019 and 2018 (in thousands, except percentages):

	Three months ended June 30,						Change

The decrease in revenue during the three and six months ended June 30, 2019 was driven primarily by decreased shipments of certain of our 100 Gbps transceivers products to one of our customers during the quarter. We are not always informed by our customers of the exact reasons for changes in their forecasts and the subsequent orders, however, we believe that the recent reduction in orders by this customer is due to excess inventory previously purchased by this customer. We continue to have active engagement with this customer and are evaluating the extent to which excess inventory may impact our future deliveries to this customer. Revenues from customers during the three and six months ended June 30, 2019 that were not customers during the same period in the prior year partially offset the decline in revenue from our 100 Gbps products.

For the three months ended June 30, 2019 and 2018, our top ten customers represented 90.9% and 94.4% of our revenue, respectively. For the six months ended June 30, 2019 and 2018, our top ten customers represented 90.5% and 94.0% of our revenue, respectively. We believe that diversifying our customer base is critical for our future success, since reliance on a small number of key customers makes our ability to forecast future results dependent upon the accuracy of the forecasts we receive from those key customers.

Gross margin		22,889	23.8	%		59,699	39.0	%

Cost of goods sold decreased by $21.1 million, or 39.1%, for the three months ended June 30, 2019 as compared to the three months ended June 30, 2018, primarily due to a 50.6% decrease in sales over the prior year. Cost of goods sold decreased by $20.1 million, or 21.6%, for the six months ended June 30, 2019 as compared to the six months ended June 30, 2018, primarily due to a 37.2% decrease in sales over the prior year. Gross margin decreased year over year due to additional production costs for our 100 Gbps datacenter products related to the implementation of enhanced quality control testing procedures. Also contributing to the decline in gross margin was a reduction in the selling price of certain of our products, including our 100 Gbps transceiver products. This price decline was in line with our expectations, however, we were unable to reduce the production costs of these products to the extent earlier projected due to the aforementioned additional testing costs combined with relatively lower production volume of these products, which caused fixed costs to be absorbed by a smaller number of units sold.

Research and development expense

Research and development expense decreased by $1.5 million, or 11.8%, for the three months ended June 30, 2019 as compared to the three months ended June 30, 2018. Research and development expense decreased by $2.0 million, or 8.4%, for the six months ended June 30, 2019 as compared to the six months ended June 30, 2018. Research and development costs consist of R&D work orders, R&D material usage and other project related costs related to 100 Gbps, 200/400 Gbps data center products, DOCSIS 3.1 capable CATV products, including remote-PHY products, and other new product development, and depreciation expense resulting from R&D equipment investments. Research and development costs decreased for the three and six months ended June 30, 2019 as compared to the three and six months ended June 30, 2018 due mainly to decreases in costs from R&D work orders, depreciation expense related to R&D equipment, materials and supplies used in R&D activities and personnel related costs.

Sales and marketing expense

Sales and marketing expense decreased slightly for the three months ended June 30, 2019 as compared to the three months ended June 30, 2018. Sales and marketing expense increased slightly for the six months ended June 30, 2019 as compared to the six months ended June 30, 2018. The changes were not material and are similar to expected rates of fluctuation in these expenses.

General and administrative expense

General and administrative expense increased by $1.0 million, or 10.0%, for the three months ended June 30, 2019 compared to the three months ended June 30, 2018. General and administrative expense increased by $2.0 million, or 10.2%, for the six months ended June 30, 2019 compared to the six months ended June 30, 2018. These increases were primarily due to increases in share-based compensation expenses, professional service fees and depreciation expenses. These increases were partially offset by a decrease in personnel related costs.

Interest income increased 264.7% and 178.8% for the three and six months ended June 30, 2019 as compared to the three and six months ended June 30, 2018, due to higher interest rates and larger cash balances.

Interest expense increased 434.1% and 610.3% for the three and six months ended June 30, 2019 as compared to the three and six months ended June 30, 2018. This increase was due to higher debt balances, including convertible senior notes and higher interest rates in the current period.

Other income (expense) for the three months ended June 30, 2019 was income of $0.5 million, a $1.1 million decrease compared to the three months ended June 30, 2018. This decrease was due to the decrease of foreign exchange gains resulting from the favorable fluctuation of certain Asian currencies against the U.S. dollar. Other income (expense) for the six months ended June 30, 2019 was income of $0.3 million, a $0.3 million decrease compared to the six months ended June 30, 2018. This decrease was due to the decrease of foreign exchange gains resulting from the favorable fluctuation of certain Asian currencies against the U.S. dollar.

Our tax provision or benefit from income taxes for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant variation due to several factors, including variability in accurately predicting our pre-tax income and loss and the mix of jurisdictions to which they relate, tax law developments and relative changes in permanent tax benefits or expenses.

Our effective tax rate for the three months ended June 30, 2019 and 2018 was (22.0%) and 22.2%, respectively. For the three months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the three months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. global intangible low-taxed income ("GILTI").

Our effective tax rate for the six months ended June 30, 2019 and 2018 was (20.6%) and 11.4% respectively. For the six months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the six months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. GILTI.

As of June 30, 2019, we had accumulated undistributed earnings generated by our foreign subsidiaries of approximately $23 million. Because $23 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the Tax Cut of Jobs Act of 2017 (the “Tax Act”), any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of our foreign investments would generally be limited to foreign and state taxes. We intend, however, to indefinitely reinvest these earnings and expects future U.S. cash generation to be sufficient to meet future U.S. cash needs.

Liquidity and Capital Resources

As of June 30, 2019, we had $64.7 million of unused borrowing capacity from all of our loan agreements. As of June 30, 2019, our cash, cash equivalents and restricted cash totaled $84.0 million. Cash and cash equivalents are held for working capital purposes and are invested primarily in money market or time deposit funds. We do not enter into investments for trading or speculative purposes. On October 17, 2016, we filed a Registration Statement on Form S-3 with the Securities and Exchange Commission, which was declared effective on November 1, 2016, providing for the public offer and sale of certain securities of the Company from time to time, at our discretion, up to an aggregate amount of $250 million. Between November 22, 2016 and March 2, 2017, the Company sold 1.6 million shares of common stock at a weighted average price of $31.55 per share, providing proceeds of $48.8 million, net of expenses and underwriting discounts and commissions. No shares of common stock were sold pursuant to this Registration Statement on Form S-3 in the three months ended June 30, 2019. On March 5, 2019, the Company issued $80.5 million of 5% convertible senior notes due 2024, bearing interest at a rate of 5% per year maturing on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms. The sale of the Notes generated net proceeds of $76.4 million, after expenses. Also refer to Note 12 “Convertible Senior Notes” to the consolidated financial statements for further discussion of the Notes.

Net increase (decrease) in cash and cash equivalents	$	25,983	$	(6,005)

Operating activities

For the six months ended June 30, 2019, net cash provided by operating activities was $7.2 million. Net cash provided by operating activities consisted of our net loss of $21.8 million, after the exclusion of non-cash items of $17.7 million. Cash increased due to a decrease in inventory of $6.3 million, a decrease in other current assets of $5.6 million, a decrease in accounts receivable from our customers of $2.1 million and an increase in accounts payable to our vendors of $1.6 million. These cash increases were offset by a decrease in accrued liabilities of $4.0 million.

For the six months ended June 30, 2018, net cash provided by operating activities was $18.1 million. Net cash provided by operating activities consisted of our net income of $10.2 million, after the exclusion of non-cash items of $20.5 million, as well as an increase in accounts payable to our vendors of $7.8 million and a decrease in accounts receivable from our customers of $11.2 million. These cash increases were offset by a decrease in accrued liabilities of $2.3 million, an increase in accrued income tax liabilities of $6.9 million, a decrease in other current assets of $1.5 million and an increase in inventory of $21.6 million.

Investing activities

For the six months ended June 30, 2019, net cash used in investing activities was $20.8 million, consisting of the purchase of additional machinery and equipment of $26.3 million, offset by a decrease in non-current assets of $5.8 million.

For the six months ended June 30, 2018, net cash used in investing activities was $35.2 million, mainly for the purchase of additional machinery and equipment and land use rights in China.

Financing activities

For the six months ended June 30, 2019, our financing activities provided $39.3 million in cash. This increase in cash was due to $76.4 million of proceeds from the issuance of convertible senior notes offset by net loan repayments of $36.5 million.

32

For the six months ended June 30, 2018, our financing activities provided $9.3 million in cash. This increase in cash was due to net borrowings of $11.5 million offset by $2.2 million of withholding taxes paid on behalf of employees related to their share-based compensation.

Loans and commitments

We have lending arrangements with several financial institutions. In the US, we have a revolving line of credit with Branch Banking and Trust (BB&T) Bank. This line of credit contains financial covenants that may limit the amount and types of debt that we may incur. As of June 30, 2019, we were in compliance with these covenants.

In Taiwan, we have revolving credit facilities with Taishin International Bank and Development Bank of Singapore (Taiwan) Ltd, credit facilities with CTBC Bank Co, Ltd. and Far Eastern International Bank Co., Ltd. and an equipment finance agreement with Chailease Finance Co., Ltd. for Prime World’s Taiwan Branch. In China, we have revolving lines of credit with China Merchants Bank Co., Ltd. and Shanghai Pudong Development Bank Co., Ltd. and a credit facility China Zheshang Bank Co., Ltd. for Global.

As of June 30, 2019, we had $64.7 million of unused borrowing capacity.

On March 5, 2019, the Company issued $80.5 million of 5% convertible senior notes due 2024. The Notes will mature on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms.

See Note 11 “Notes Payable and Long-term Debt” and Note 12 “Convertible Senior Notes” of our Condensed Consolidated Financial Statements for a description of our notes payable and long-term debt and convertible senior notes.

China factory construction

On February 8, 2018, we entered into a construction contract with Zhejiang Xinyu Construction Group Co., Ltd. for the construction of a new factory and other facilities at our Ningbo, China location. Construction costs for these facilities under this contract are estimated to total approximately $27.5 million. As of June 30, 2019, approximately $17.7 million of this total cost has been incurred, with the remaining portion due as the construction progresses. Construction under this contract is expected to be completed in early 2020.

Future liquidity needs

We believe that our existing cash and cash equivalents, cash flows from our operating activities, and available credit will be sufficient to meet our anticipated cash needs for the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support our research and development efforts, the expansion of our sales and marketing activities, the introduction of new and enhanced products, the construction of a new factory and other facilities at our Ningbo, China location, changes in our manufacturing capacity and the continuing market acceptance of our products.  In the event we need additional liquidity, we will explore additional sources of liquidity. These additional sources of liquidity could include one, or a combination, of the following: (i) issuing equity or debt securities, (ii) incurring indebtedness secured by our assets and (iii) selling product lines, other assets and/or portions of our business. There can be no guarantee that we will be able to raise additional funds on terms acceptable to us, or at all.

Contractual Obligations and Commitments

1) We have several loan and security agreements in China, Taiwan and the U.S. that provide various credit facilities, including lines of credit, bank acceptance payable and term loans. The amount presented in the table represents the principal portion and estimated interest expense for the obligations.

2) We issued convertible senior notes due 2024. The amount present in the table represents the principal portion and estimated interest expense for the obligations.

3) We have entered into various non-cancellable operating lease agreements for our offices in Taiwan and the U.S.

Inflation

We believe that the relatively low rate of inflation in the U.S. over the past few years has not had a significant impact on our net sales and revenues or on income from continuing operations or on the prices of raw materials. To the extent we expand our operations in China and Taiwan, such actions may result in inflation having a more significant impact on our operating results in the future.

Off-Balance Sheet Arrangements

For the three months ended June 30, 2019, we did not, and we do not currently, have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

In our annual report on Form 10-K for the year ended December 31, 2018 and in the Notes to the Financial Statements herein, we identify our most critical accounting policies. In preparing the financial statements, we make assumptions, estimates and judgments that affect the amounts reported. We periodically evaluate our estimates and judgments that are most critical in nature which are related to revenue recognition, allowance for doubtful accounts, inventory reserves, impairment of long-lived assets (excluding goodwill and other indefinite-lived intangible assets), goodwill and other indefinite-lived intangible assets, purchase price allocation of acquisitions, service and product warranties, and income taxes. Our estimates are based on historical experience and on our future expectations that we believe are reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results are likely to differ from our current estimates and those differences may be material.

Item 3.   Quantitative and Qualitative Disclosures about Market Risk

For quantitative and qualitative disclosures about market risk affecting the Company, see Item 7A – Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. We do not believe the Company’s exposure to market risk has changed materially since December 31, 2018.

Item 4.   Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2019. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.

34

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three month period covered by this Quarterly Report on Form 10-Q, which were identified in connection with management’s evaluation required by the Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1.   Legal Proceedings

From time to time, we may be subject to legal proceedings and litigation arising in the ordinary course of business, including, but not limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. We record a loss provision when we believe it is both probable that a liability has been incurred and the amount can be reasonably estimated. Unless otherwise disclosed, we are unable to estimate the possible loss or range of loss for the legal proceeding described below.

Except for the lawsuits described below, we believe that there are no claims or actions pending or threatened against us, the ultimate disposition of which would have a material adverse effect on us.

Class Action and Shareholder Derivative Litigation

On August 5, 2017, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against us and two of our officers in Mona Abouzied v. Applied Optoelectronics, Inc., Chih-Hsiang (Thompson) Lin, and Stefan J. Murry, et al., Case No. 4:17-cv-02399. The complaint in this matter seeks class action status on behalf of our shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against us, our chief executive officer, and our chief financial officer, arising out of our announcement on August 3, 2017 that “we see softer than expected demand for our 40G solutions with one of our large customers that will offset the sequential growth and increased demand we expect in 100G.” A second, related action was filed by Plaintiff Chad Ludwig on August 16, 2017 (Case No. 4:17-cv-02512) in the Southern District of Texas. The two cases were consolidated before Judge Vanessa D. Gilmore. On January 22, 2018, the court appointed Lawrence Rougier as Lead Plaintiff and Levi & Korinsky LLP as Lead Counsel. Lead Plaintiff filed an amended consolidated class action complaint on March 6, 2018. The amended complaint requests unspecified damages and other relief. The Company filed a motion to dismiss on April 4, 2018, which was denied on March 28, 2019.  We dispute the allegations, and we intend to continue to vigorously defend against these claims.  On May 15, 2019, Lead Plaintiff filed a motion for leave to amend the consolidated class action complaint for the purpose of adding named Plaintiffs Richard Hamilton, Kenneth X. Luthy, Roy H. Cetlin, and John Kugel (together with Lead Plaintiff Lawrence Rougier, “Plaintiffs”) to the case. The court granted the motion on May 16, 2019. The substantive allegations in the Plaintiffs’ operative second amended consolidated class action complaint remain unchanged. On May 28, 2019, Plaintiffs filed a motion seeking to certify the case as a class action pursuant to Federal Rule of Civil Procedure 23 and seeking appointment of Plaintiffs as class representatives and Levi & Korsinsky as class counsel. On July 12, 2019, we filed a response in opposition to the motion for class certification. The deadline for Plaintiffs’ reply brief is August 26, 2019. The case is currently in the early stages of discovery, and fact discovery is scheduled to be completed by June 1, 2020.  At this early stage, we are not yet able to determine the likelihood of loss, if any, arising from this matter. On August 7, 2018, Plaintiff Lei Jin filed a purported derivative action on behalf of nominal defendant Applied Optoelectronics, Inc. in the U.S. District Court for the Southern District of Texas against our chief executive officer, chief financial officer and board of directors (Case No. 4:18-cv-02713).  This case was consolidated with a later filed derivative lawsuit filed by Plaintiff Yiu Kwong Ng in the U.S. District Court for the Southern District of Texas (Case No. 4:18-cv-4751). The allegations in the consolidated derivative complaints are substantially similar to those underlying the Abouzied securities class action and the Taneja securities class action discussed below. The consolidated derivative action is stayed pending a ruling on defendants’ forthcoming motion to dismiss in the Taneja securities class action.

On October 1, 2018, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against us and two of our officers in Gaurav Taneja v. Applied Optoelectronics, Inc., Thompson Lin, and Stefan Murry, Case No. 4:18-cv-03544. The complaint in this matter seeks class action status on behalf of the Company’s shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, our chief executive officer, and our chief financial officer, arising out of our announcement on September 28, 2018 that we were revising our third quarter revenue guidance due to “an issue with a small percentage of 25G lasers within a specific customer environment.” This case was consolidated with two identical cases styled Davin Pokoik v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry, Case No. 4:18-cv-3722 and Stephen McGrath v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry.  Mark Naglich was appointed as Lead Plaintiff on the consolidated matter on January 4, 2019.  Lead Plaintiff filed an amended consolidated complaint on March 5, 2019, and we filed a motion to dismiss the amended consolidated complaint on May 6, 2019. On July 5, 2019, Plaintiff filed a response in opposition to the motion

36

dismiss. The deadline for our reply brief in support of the motion to dismiss is August 5, 2019. We dispute the allegations and intend to vigorously contest the matter.

Books and Records Request

On April 10, 2019, stockholder David Bono filed a complaint in the Delaware Court of Chancery against us seeking to inspect certain corporate books and records pursuant to Section 220 of the Delaware General Corporation Law.  The lawsuit is styled David Bono v. Applied Optoelectronics, Inc., Case No. 2019-0275 (Del. Ch. 2019).  The complaint does not seek damages but seeks the plaintiff’s costs and expenses, including attorneys’ fees, as well as the requested books and records.  On July 5, 2019, by agreement of the parties, the Vice Chancellor issued an order staying the case to allow the parties to seek resolution of the dispute outside of litigation. A joint status report is due to the Court by September 3, 2019.

Item 1A.  Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all other information contained in our Quarterly Report on Form 10-Q, including our consolidated financial statements and related notes. If any of the following risks actually occur, we may be unable to conduct our business as currently planned and our financial condition and results of operations could be seriously harmed. In addition, the trading price of our common stock could decline due to the occurrence of any of these risks and you may lose all or part of your investment.

Risks Inherent in Our Business

We are dependent on our key customers for a significant portion of our revenue and the loss of, or a significant reduction in orders from, any of our key customers would adversely impact our revenue and results of operations.

We generate much of our revenue from a limited number of customers. For each year ended 2018, 2017 and 2016 and the three and six months ended June 30, 2019, our top ten customers represented 92.9%, 94.9%, 95.5%, 90.9% and 90.5% of our revenue, respectively. In 2018, Facebook represented 38.3% of our revenue, Microsoft represented 22.1% of our revenue and Amazon represented 12.1% of our revenue. As a result, the loss of, or a significant reduction in orders from any of our key customers would materially and adversely affect our revenue and results of operations. We typically do not have long-term contracts with our customers and instead rely on recurring purchase orders. However, many of our current revenue expectations and forecasts reflect significant anticipated orders from a limited number of key customers. If our key customers do not continue to purchase our existing products or fail to purchase additional products from us, our revenue would decline and our results of operations would be adversely affected. 

Changes in our customers’ demands may negatively affect our sales and revenue. For example, several of our largest customers have informed us that new architectures being implemented in their datacenters may reduce their demand for 100 Gbps optical transceivers compared to their prior forecasts. This would negatively impact our anticipated revenue from these customers. If we cannot sufficiently increase revenue from these new customers and our other existing customers, then our overall revenue may be adversely affected.

Adverse events affecting our key customers could also negatively affect our ability to retain their business and obtain new purchase orders, which could adversely affect our revenue and results of operations. For example, in recent years, there has been consolidation among various network equipment manufacturers and this trend is expected to continue. We are unable to predict the impact that industry consolidation would have on our existing or potential customers. We may not be able to offset any potential decline in revenue arising from the consolidation of our existing customers with revenue from new customers or additional revenue from the merged company.

Customer demand is difficult to forecast accurately and, as a result, we may be unable to match production with customer demand.

We make planning and spending decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements, based on our estimates of product demand and customer requirements. Our products are typically purchased pursuant to

37

individual purchase orders. While our customers may provide us with their demand forecasts, they are typically not contractually committed to buy any quantity of products beyond firm purchase orders. Furthermore, many of our customers may increase, decrease, cancel or delay purchase orders already in place without significant penalty. The short-term nature of commitments by our customers and the possibility of unexpected changes in demand for their products reduce our ability to accurately estimate future customer requirements. On occasion, customers may require rapid increases in production, which can strain our resources, cause our manufacturing to be negatively impacted by materials shortages, necessitate more onerous procurement commitments and reduce our gross margin. We may not have sufficient capacity at any given time to meet the volume demands of our customers, or one or more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. If any of our major customers decrease, stop or delay purchasing our products for any reason, we will likely have excess manufacturing capacity or inventory and our business and results of operations would be harmed.

If our customers do not qualify our products for use on a timely basis, our results of operations may suffer.

Prior to the sale of new products, our customers typically require us to “qualify” our products for use in their applications. At the successful completion of this qualification process, we refer to the resulting sales opportunity as a “design win.” Additionally, new customers often audit our manufacturing facilities and perform other evaluations during this qualification process. The qualification process involves product sampling and reliability testing and collaboration with our product management and engineering teams in the design and manufacturing stages. If we are unable to accurately predict the amount of time required to qualify our products with customers, or are unable to qualify our products with certain customers at all, then our ability to generate revenue could be delayed or our revenue would be lower than expected and we may not be able to recover the costs associated with the qualification process or with our product development efforts, which would have an adverse effect on our results of operations.

In addition, due to rapid technological changes in our markets, a customer may cancel or modify a design project before we have qualified our product or begun volume manufacturing of a qualified product. It is unlikely that we would be able to recover the expenses for cancelled or unutilized custom design projects. Some of these unrecoverable expenses for cancelled or unutilized custom design projects may be significant. It is difficult to predict with any certainty whether our customers will delay or terminate product qualification or the frequency with which customers will cancel or modify their projects, but any such delay, cancellation or modification would have a negative effect on our results of operations.

Our ability to successfully qualify and scale capacity for new technologies and products is important to our ability to grow our business and market presence, and we may invest a significant amount to scale our capacity to meet potential demand from customers for our new technologies and products. If we are unable to qualify and sell any of our new products in volume, on time, or at all, our results of operations may be adversely affected.

We face intense competition which could negatively impact our results of operations and market share.

The markets into which we sell our products are highly competitive. Our competitors range from large, international companies offering a wide range of products to smaller companies specializing in niche markets. Current and potential competitors may have substantially greater name recognition, financial, marketing, research and manufacturing resources than we do, and there can be no assurance that our current and future competitors will not be more successful than us in specific product lines or markets. Some of our competitors may also have better-established relationships with our current or potential customers. Some of our competitors have more resources to develop or acquire new products and technologies and create market awareness for their products and technologies. In addition, some of our competitors have the financial resources to offer competitive products at below-market pricing levels that could prevent us from competing effectively and result in a loss of sales or market share or cause us to lower prices for our products. In recent years, there has been consolidation in our industry and we expect such consolidation to continue. Consolidation involving our competitors could result in even more intense competition. Network equipment manufacturers, who are our customers, and network service providers may decide to manufacture the optical subsystems incorporated into their network systems in-house instead of outsourcing such products to companies such as us. We also encounter potential customers that, because of existing relationships with our competitors, are committed to the products offered by our competitors.

38

We must continually develop successful new products and enhance existing products, and if we fail to do so or if our release of new or enhanced products is delayed, our business may be harmed.

The markets for our products are characterized by frequent new product introductions, changes in customer requirements and evolving industry standards, all with an underlying pressure to reduce cost and meet stringent reliability and qualification requirements. Our future performance will depend on our successful development, introduction and market acceptance of new and enhanced products that address these challenges. If we are unable to make our new or enhanced products commercially available on a timely basis, we may lose existing and potential customers and our financial results would suffer.

In addition, due to the costs and length of research, development and manufacturing process cycles, we may not recognize revenue from new products until long after such expenditures, if at all, and our margins may decrease if our costs are higher than expected, adversely affecting our financial condition and results of operations.

Although the length of our product development cycle varies widely by product and customer, it may take 18 months or longer before we receive our first order. As a result, we may incur significant expenses long before customers accept and purchase our products.

Product development delays may result from numerous factors, including:

● modification of product specifications and customer requirements;

● unanticipated engineering complexities;

● difficulties in reallocating engineering resources and overcoming resource limitations; and

● rapidly changing technology or competitive product requirements.

The introduction of new products by us or our competitors and other changes in our customer’s demands could result in a slowdown in demand for our existing products and could result in a write-down in the value of our inventory. We have in the past experienced periodic fluctuations in demand for existing products and delays in new product development, and such fluctuations will likely occur in the future. To the extent we fail to qualify our products and obtain their approval for use, which we refer to as a design win, or experience product development delays for any reason, our competitive position would be adversely affected and our ability to grow our revenue would be impaired.

Furthermore, our ability to enter a market with new products in a timely manner can be critical to our success because it is difficult to displace an existing supplier for a particular type of product once a customer has chosen a supplier, even if a later-to-market product provides better performance or cost efficiency.

The development of new, technologically advanced products is a complex and uncertain process requiring frequent innovation, highly-skilled engineering and development personnel and significant capital, as well as the accurate anticipation of technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully or on a timely basis. Further, we cannot assure you that our new products will gain market acceptance or that we will be able to respond effectively to product introductions by competitors, technological changes or emerging industry standards. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, license these technologies from third parties, or remain competitive in our markets.

Our revenues, growth rates and operating results are likely to fluctuate significantly as a result of factors that are outside our control, which could adversely impact our operating results.

Our revenues, growth rates and operating results are likely to fluctuate significantly in the future as a result of factors that are outside our control. We may not achieve similar revenues, growth rates or operating results in future periods. Our revenues, growth rates and operating results for any prior quarterly or annual period should not be relied upon as any indication of our future revenues, growth rates or operating results. The timing of order placement, size of orders and satisfaction of contractual customer acceptance criteria, changes in the pricing of our products due to competitive pressures as well as order or shipment delays or deferrals, with respect to our products, may cause material

39

fluctuations in revenues. Our lengthy sales cycle, which may extend to more than one year, may cause our revenues and operating results to vary from period to period and it may be difficult to predict the timing and amount of any variation. Delays or deferrals in purchasing decisions by our customers may increase as we develop new or enhanced products for existing and new markets, including automotive and biotechnology markets. Our current and anticipated future dependence on a small number of customers increases the revenue impact of each such customer’s decision to delay or defer purchases from us, or decision not to purchase products from us. Our expense levels in the future will be based, in large part, on our expectations regarding future revenue sources and, as a result, operating results for any quarterly period in which anticipated material orders fail to occur, or are delayed or deferred, could be significantly harmed.

We are subject to the cyclical nature of the markets in which we compete and any future downturn will likely reduce demand for our products and revenue.

In each of our target markets, including the CATV market, our sales depend on the aggregate capital expenditures of service providers as they build out and upgrade their network infrastructure. These markets are highly cyclical and characterized by constant and rapid technological change, price erosion, evolving standards and wide fluctuations in product supply and demand. In the past, these markets have experienced significant downturns, often connected with, or in anticipation of, the maturation of product cycles. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Our historical results of operations have been subject to these cyclical fluctuations, and we may experience substantial period to period fluctuations in our future results of operations. Any future downturn in any of the markets in which we compete could significantly reduce the demand for our products and therefore may result in a significant reduction in our revenue. Our revenue and results of operations may be materially and adversely affected in the future due to changes in demand from individual customers or cyclical changes in any of the markets utilizing our products. We may not be able to accurately predict these cyclical fluctuations and the impact that these fluctuations may have on our revenue and operating results.

If we encounter manufacturing problems, we may lose sales and damage our customer relationships.

We may experience delays, disruptions or quality control problems in our manufacturing operations. These and other factors may cause less than acceptable yields at our facility. Manufacturing yields depend on a number of factors, including the quality of available raw materials, the degradation or change in equipment calibration and the rate and timing of the introduction of new products. Changes in manufacturing processes required as a result of changes in product specifications, changing customer needs and the introduction of new product lines may significantly reduce our manufacturing yields, resulting in low or negative margins on those products. In addition, we use our Molecular Beam Epitaxy, or MBE, fabrication process to make our lasers, in addition to Metal Organic Chemical Vapor Deposition, or MOCVD, the technique most commonly used in optical manufacturing by communications optics vendors, and our MBE fabrication process relies on custom-manufactured equipment. If our MBE or MOCVD fabrication facility in Sugar Land, Texas were to be damaged or destroyed for any reason, our manufacturing process would be severely disrupted. Any such manufacturing problems would likely delay product shipments to our customers. For example, shipments of certain of our 100 Gbps transceiver products to one of our customers decreased during the three months ended September 30, 2018 due to customer concerns about failures of similar products shipped previously. During the quarter, we conducted extensive testing of our products to demonstrate that any potentially affected units could be nearly eliminated from future shipments, and we subsequently resumed shipments with the customer’s agreement. However, additional testing costs and costs to enhance the ongoing monitoring of product quality may adversely affect the results of our operations. Manufacturing problems and any such delays would negatively affect our sales and revenue and could negatively affect our competitive position and reputation. We may also experience delays in production, typically in February, during the Lunar New Year holiday when our facilities in China and Taiwan are closed.

Given the high fixed costs associated with our vertically integrated business, a reduction in demand for our products will likely adversely impact our gross profits and our results of operations.

We have a high fixed cost base due to our vertically integrated business model, including the fact that 2,529 of our employees as of December 31, 2018 were employed in manufacturing and research and development operations. We may not be able to adjust these fixed costs quickly to adapt to rapidly changing market conditions. Our gross profit and gross margin are greatly affected by our sales volume and volatility on a quarterly basis and the corresponding absorption of fixed manufacturing overhead expenses. In addition, because we are a vertically integrated manufacturer, insufficient demand for our products may subject us to the risk of high inventory carrying costs and increased inventory

40

obsolescence. Given our vertical integration, the rate at which we turn inventory has historically been low when compared to our cost of sales. We do not expect this to change significantly in the future and believe that we will have to maintain a relatively high level of inventory compared to our cost of sales. As a result, we continue to expect to have a significant amount of working capital invested in inventory. We may be required to write down inventory costs in the future and our high inventory costs may have an adverse effect on our gross profits and our results of operations. 

Increasing costs and shifts in product mix may adversely impact our gross margins.

Our gross margins on individual products and among products fluctuate over each product’s life cycle. Our overall gross margins have fluctuated from period to period as a result of shifts in product mix, the introduction of new products, decreases in average selling prices and our ability to reduce product costs, and these fluctuations are expected to continue in the future. We may not be able to accurately predict our product mix from period to period, and as a result we may not be able to forecast accurately our overall gross margins. The rate of increase in our costs and expenses may exceed the rate of increase in our revenue, either of which would materially and adversely affect our business, our results of operations and our financial condition.

If the CATV market does not continue to develop as we expect, or if there is any downturn in this market, our business would be adversely affected.

Historically, we have generated much of our revenue from the CATV market. In 2018, 2017 and 2016, the CATV market represented 19.3%, 15.9% and 16.7% of our revenue, respectively. In the CATV market, we are relying on expected increasing demand for bandwidth-intensive services and applications such as on-demand television programs, high-definition television channels, or HDTV, social media, peer-to-peer file sharing and online video creation and viewing from network service providers. Without network and bandwidth growth, the need for our products will not increase and may decline, adversely affecting our financial condition and results of operations. Although demand for broadband access is increasing, network and bandwidth growth may be limited by several factors, including an uncertain regulatory environment, high infrastructure costs to purchase and install equipment and uncertainty as to which competing content delivery solution, such as telecommunications, wireless or satellite, will gain the most widespread acceptance. If the trend of outsourcing for the design and manufacture of CATV equipment does not continue, or continues at a slower pace than currently expected, our customers’ demand for our design and manufacturing services may not grow as quickly as expected. If expectations for the growth of the CATV market are not realized, our financial condition and results of operations will be adversely affected. In addition, if the CATV market is adversely impacted, whether due to competitive pressure from telecommunication service providers, regulatory changes, or otherwise, our business would be adversely affected. We may not be able to offset any potential decline in revenue from the CATV market with revenue from new customers in other markets.

We have limited operating history in the telecom and FTTH markets, and our business could be harmed if these markets do not develop as we expect.

For 2018 and 2017, respectively, we generated 4.9% and 3.4% of our revenue from the telecom market and 0.3%, and 0.1% of our revenue from the FTTH market. In the telecom market, we generally have sold products that were originally designed for other markets (such as internet data center or FTTH) or are variations of such products. As we gain experience in this market, we have begun to develop products specifically designed for telecom customers. Given our limited experience in this market, the products that we develop may prove to be unsuitable for customer use, or we may be unable to derive profit margins from this market that are similar to what we derive from our other markets. The products that we offer in the FTTH market are relatively new and have not yet gained widespread customer acceptance. For example, our WDM-PON products designed for the FTTH market, have not, and may never, gain widespread acceptance by large internet service providers. Our business in this market is dependent on the deployment of our optical components, modules and subassemblies. We are relying on increasing demand for bandwidth-intensive services and telecommunications service providers’ acceptance and deployment of WDM-PON as a technology supporting 1 Gbps service to the home. Without network and bandwidth growth and adoption of our solutions by operators in these markets, we will not be able to sell our products in these markets in high volume or at our targeted margins, which would adversely affect our financial condition and results of operations. For example, WDM-PON technology may not be adopted by equipment and service providers in the FTTH market as rapidly as we expect or in the volumes we need to achieve acceptable margins. Network and bandwidth growth may be limited by several factors, including an uncertain regulatory environment, high infrastructure costs to purchase and install equipment and uncertainty as to which competing content delivery solution, such as CATV, will gain the most widespread acceptance. In addition, as we enter

41

new markets or expand our product offerings in existing markets, our margins may be adversely affected due to competition in those markets and commoditization of competing products. If our expectations for the growth of these markets are not realized, our financial condition and results of operations will be adversely affected.

Our financial results may vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.

Our quarterly revenue and operating results have varied in the past and will likely continue to vary significantly from quarter-to-quarter. This variability may lead to volatility in our stock price as research analysts and investors respond to these quarterly fluctuations. These fluctuations are due to numerous factors, including:

● the timing, size and mix of sales of our products;

● fluctuations in demand for our products, including the increase, decrease, rescheduling or cancellation of significant customer orders;

● our ability to design, manufacture and deliver products which meet customer requirements in a timely and cost-effective manner;

● new product introductions and enhancements by us or our competitors;

● the gain or loss of key customers;

● the rate at which our present and potential customers and end users adopt our technologies;

● changes in our pricing and sales policies or the pricing and sales policies of our competitors;

● seasonality of certain of our products and manufacturing capabilities;

● quality control or yield problems in our manufacturing operations;

● supply disruption for certain raw materials and components used in our products;

● capacity constraints of our outside contract manufacturers for a portion of the manufacturing process for some of our products;

● length and variability of the sales cycles of our products;

● unanticipated increases in costs or expenses;

● the loss of key employees;

● different capital expenditure and budget cycles for our customers, affecting the timing of their spending for our products;

● political stability in the areas of the world in which we operate;

● fluctuations in foreign currency exchange rates;

● changes in accounting rules;

● changes in or limitations imposed by trade protection laws or other regulatory orders or requirements in the United States or in other countries, including tariffs, sanctions, or other costs, restrictions, or requirements which may affect our ability to import or export our products to or from various countries;

42

● trade-related government actions that impose barriers or restrictions that would impact our ability to sell or ship products to Huawei or other customers;

● the evolving and unpredictable nature of the markets for products incorporating our solutions; and

● general economic conditions and changes in such conditions specific to our target markets.

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect our quarterly and annual operating results. In addition, a significant amount of our operating expenses is relatively fixed in nature due to our internal manufacturing, research and development, sales and general administrative efforts. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify the adverse impact of such revenue shortfall on our results of operations. For these reasons, you should not rely on quarter-to-quarter comparisons of our results of operations as an indicator of future performance. Moreover, our operating results may not meet our announced guidance or the expectations of research analysts or investors, in which case the price of our common stock could decrease significantly. There can be no assurance that we will be able to successfully address these risks.

Our indebtedness and liabilities could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition and results of operations and impair our ability to satisfy our obligations under our indebtedness.

As of June 30, 2019, we had approximately $128.8 million of consolidated indebtedness. We may also incur additional indebtedness to meet future financing needs. Our indebtedness could have significant negative consequences for our security holders and our business, results of operations and financial condition by, among other things:

● increasing our vulnerability to adverse economic and industry conditions;

● limiting our ability to obtain additional financing;

● requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of cash available for other purposes;

● limiting our flexibility to plan for, or react to, changes in our business;

● diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon conversion of the Notes; and

● placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness, including the Notes, and our cash needs may increase in the future. In addition, our existing Credit Facility with BB&T, contains, and any future indebtedness that we may incur may contain, financial and other restrictive covenants that limit our ability to operate our business, raise capital or make payments under our other indebtedness. If we fail to comply with these covenants or to make payments under our indebtedness when due, then we would be in default under that indebtedness, which could, in turn, result in that and our other indebtedness becoming immediately payable in full.

We depend on key personnel to develop and maintain our technology and manage our business in a rapidly changing market.

The continued services of our executive officers and other key engineering, sales, marketing, manufacturing and support personnel is essential to our success. For example, our ability to achieve new design wins depends upon the experience and expertise of our engineers. Any of our key employees, including our Chief Executive Officer, Chief Financial Officer, Senior Vice President and North America General Manager and Senior Vice President and Asia General Manager, may resign at any time. We do not have key person life insurance policies covering any of our employees. To implement our business plan, we also intend to hire additional employees, particularly in the areas of

43

engineering, manufacturing and sales. Our ability to continue to attract and retain highly skilled employees is a critical factor in our success. Competition for highly skilled personnel is intense. We may not be successful in attracting, assimilating or retaining qualified personnel to satisfy our current or future needs. Our ability to develop, manufacture and sell our products, and thus our financial condition and results of operations, would be adversely affected if we are unable to retain existing personnel or hire additional qualified personnel.

We depend on a limited number of suppliers and any supply interruption could have an adverse effect on our business.

We depend on a limited number of suppliers for certain raw materials and components used in our products. Some of these suppliers could disrupt our business if they stop, decrease or delay shipments or if the materials or components they ship have quality or reliability issues. Some of the raw materials and components we use in our products are available only from a sole source or have been qualified only from a single supplier. Furthermore, other than our current suppliers, there are a limited number of entities from whom we could obtain certain materials and components. We may also face shortages if we experience increased demand for materials or components beyond what our qualified suppliers can deliver. Our inability to obtain sufficient quantities of critical materials or components could adversely affect our ability to meet demand for our products, adversely affecting our financial condition and results of operations.

We typically have not entered into long-term agreements with our suppliers and, therefore, our suppliers could stop supplying materials and components to us at any time or fail to supply adequate quantities of materials or components to us on a timely basis. It is difficult, costly, time consuming and, on short notice, sometimes impossible for us to identify and qualify new suppliers. Our customers generally restrict our ability to change the components in our products. For more critical components, any changes may require repeating the entire qualification process. Our reliance on a limited number of suppliers or a single qualified vendor may result in delivery and quality problems, and reduced control over product pricing, reliability and performance.

We depend upon outside contract manufacturers for a portion of the manufacturing process for some of our products.

Almost all of our products are manufactured internally. However, we also rely upon manufacturers in China, Taiwan and other Asia locations to provide back-end manufacturing and produce the finished portion of a few of our products. Our reliance on a contract manufacturer for these products makes us vulnerable to possible capacity constraints and reduced control over delivery schedules, manufacturing yields, manufacturing quality/controls and costs. If one or more of our contract manufacturers is unable to meet our customer demand in a timely fashion, this could have a material adverse effect on the revenue from our products. If one or more contract manufacturers for one of our products was unable or unwilling to manufacture such product in required volumes and at high quality levels or to continue our existing supply arrangement, we would have to identify, qualify and select an acceptable alternative contract manufacturer or move these manufacturing operations to our internal manufacturing facilities. An alternative contract manufacturer may not be available to us when needed or may not be in a position to satisfy our quality or production requirements on commercially reasonable terms, including price. Any significant interruption in manufacturing our products would require us to reduce our supply of products to our customers, which in turn, would reduce our revenue, harm our relationships with the customer of these products and cause us to forego potential revenue opportunities.

Our products could contain defects that may cause us to incur significant costs or result in a loss of customers.

Our products are complex and undergo quality testing as well as formal qualification by our customers. Our customers’ testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios and over varying amounts of time. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing or other unforeseen reasons. Any such failures could delay product shipments to our customers or result in a loss of customers. For example, shipments of certain of our 100 Gbps transceiver products to one of our customers decreased during the three months ended September 30, 2018 due to customer concerns about failures of similar products shipped previously. As a result, we could incur significant costs to repair or replace defective products under warranty, particularly when such failures occur in installed systems. Our products are typically embedded in, or deployed in conjunction with, our customers’ products, which incorporate a variety of components, modules and

44

subsystems and may be expected to interoperate with modules produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. We face this risk because our products are widely deployed in many demanding environments and applications worldwide. In addition, we may in certain circumstances honor warranty claims after the warranty has expired or for problems not covered by warranty to maintain customer relationships. Any significant product failure could result in litigation, damages, repair costs and lost future sales of the affected product and other products, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems, all of which would harm our business. Although we carry product liability insurance, this insurance may not adequately cover our costs arising from defects in our products or otherwise.

Our loan agreements contain restrictive covenants that may adversely affect our ability to conduct our business.

We have lending arrangements with several financial institutions, including loan agreements with Branch Banking and Trust (BB&T) Bank in the U.S., credit facilities with Taishin International Bank, Development Bank of Singapore and CTBC Bank, an equipment finance agreement with Chailease Finance Co., Ltd. in Taiwan and credit facilities with China Merchants Bank Co. Ltd., Shanghai Pudong Development Bank Co., Ltd. and China Zheshang Bank Co., Ltd. in China. Our loan agreements governing our long-term debt obligations in the U.S. and Asia contain certain financial and operating covenants that limit our management’s discretion with respect to certain business matters. Among other things, these covenants require us to maintain certain financial ratios and restrict our ability to incur additional debt, create liens or other encumbrances, change the nature of our business, sell or otherwise dispose of assets and merge or consolidate with other entities. In addition, the Indenture governing the Notes contains covenants that limit our ability and the ability of our subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue disqualified stock; and (ii) create or incur liens. These restrictions may limit our flexibility in responding to business opportunities, competitive developments and adverse economic or industry conditions. Any failure by us or our subsidiaries to comply with these agreements could harm our business, financial condition and operating results. In addition, our obligations under our loan agreements with BB&T are secured by our accounts receivable, inventory, intellectual property, and all business assets including real estate and equipment. Our credit facilities with Shanghai Pudong Development Bank Co., Ltd. and China Zheshang Bank Co., Ltd. are secured by real estate. A breach of any of covenants under our loan agreements, or a failure to pay interest or indebtedness when due under any of our credit facilities could result in a variety of adverse consequences, including the acceleration of our indebtedness.

We may not be able to obtain additional capital when desired, on favorable terms or at all.

We operate in a market that makes our prospects difficult to evaluate and, to remain competitive, we will be required to make continued investments in capital equipment, facilities and technological improvements. We expect that substantial capital will be required to expand our manufacturing capacity and fund working capital for anticipated growth. If we do not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs, we may need additional financing to implement our business strategy, which includes:

● expansion of research and development;

● expansion of manufacturing capabilities;

● hiring of additional technical, sales and other personnel; and

● acquisitions of complementary businesses.

If we raise additional funds through the issuance of our common stock or convertible securities, the ownership interests of our stockholders could be significantly diluted. These newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. Additional financing may not, however, be available on terms favorable to us, or at all, if and when needed, and our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our infrastructure or respond to competitive pressures could be significantly limited. If we cannot raise required capital when needed, including under our Registration Statement filed with the SEC in October 2016, we may be unable to meet the demands of existing and prospective customers, adversely affecting our sales and market opportunities and consequently our business, financial condition and results of operations.

45

Data breaches and cyberattacks could compromise our operations, our customers’ operations, or the operations of our contract manufacturers upon whom we rely, and cause significant damage to our business and reputation.

Cyberattacks have become more prevalent and much harder to detect and defend against. Companies, including companies in our industry, have been increasingly subject to a wide variety of security incidents, cyberattacks and other attempts to gain unauthorized access to their systems or to deny access and disrupt their systems and operations. These threats can come from a variety of sources, ranging in sophistication from an individual hacker to a state-sponsored attack. Cyber threats may be generic, or they may be custom-crafted against our information systems.

In the ordinary course of our business, we and our data center customers maintain sensitive data on our respective networks, including intellectual property, employee personal information and proprietary or confidential business information relating to our business and that of our customers and business partners. The secure maintenance of this information is critical to our business and reputation. Despite our implementation of network security measures, our network and storage applications have been subject to computer viruses, ransomware and other forms of cyber terrorism. Also, despite our implementation of security measures, we are not able to guarantee that we can prevent unauthorized access by hackers or breaches due to operator error, malfeasance or other system disruptions. Our customers’ network and storage applications may be subject to similar disruptions. It is often difficult to anticipate or immediately detect such incidents and the damage caused by such incidents. Data breaches and any unauthorized access or disclosure of our information, employee information or intellectual property could compromise our business, trade secrets and other sensitive business information, any of which could result in legal action against us, exposure of our intellectual property to our competitors, damages, fines and other adverse effects. A data security breach could also lead to public exposure of personal information of our employees, customers and others. Any such theft, loss or misuse of personal data collected, used, stored or transferred by us to run our business could result in significantly increased security costs or costs related to defending legal claims. Cyberattacks, such as computer viruses or other forms of cyber terrorism, have disrupted access to some of our network applications. In past incidents we have been able to recover quickly without material financial impact, however such disruptions in the future may result in delays or cancellations of customer orders or delays or additional costs to produce and ship our products. Data security breaches involving our data center customers could affect their financial condition and ability to continue to purchase our products. Further, cyberattacks may cause us to incur significant remediation costs, result in product development delays, disrupt key business operations and divert attention of management and key information technology resources. These incidents could also subject us to liability, expose us to significant expense and cause significant harm to our reputation and business.

Changes in U.S. and international trade policies, particularly with regard to China, may materially and adversely impact our business and operating results.

The U.S. government has recently made statements and taken certain actions that have led and may lead to further changes to U.S. and international trade policies, including recently-imposed tariffs affecting certain products manufactured in China. Since the beginning of 2018, there has been increasing rhetoric, in some cases coupled with legislative or executive action, from several U.S. and foreign leaders regarding the possibility of instituting tariffs on the foreign imports of certain materials. Three rounds of U.S. tariffs on imports from China have become effective in July 2018, August 2018 and September 2018 (respectively the “U.S. Tariffs on China Imports”). A limited number of our products that have a China country of origin are currently subject to the U.S. Tariffs on China Imports.

It is unknown whether and to what extent new tariffs (or other new laws or regulations) will be adopted, or the effect that any such actions would have on us or our industry. A significant portion of our manufacturing operations is based in Ningbo, China; therefore, if any new tariffs, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated or if China or other affected countries take further retaliatory trade actions, such changes could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Furthermore, the implementation of trade tariffs both globally and between the U.S. and China specifically carries the risk of negatively impacting China’s overall economic condition, which could have negative repercussions on us. Imposition of tariffs could cause a decrease in the sales of our products to customers located in China or other customers selling to Chinese end users, which would directly impact our business.

Significant changes to existing international trade agreements could also lead to sourcing or logistics disruption resulting from import delays or the imposition of increased tariffs on our sourcing partners.  For example, the Chinese

46

government could, among other things, require the use of local suppliers, compel companies that do business in China to partner with local companies to conduct business and provide incentives to government-backed local customers to buy from local suppliers. Changes in, and responses to, U.S. trade policy could reduce the competitiveness of our products and cause our sales and revenues to drop, which could materially and adversely impact our business and results of operations.

We face a variety of risks associated with our international sales and operations.

We currently derive, and expect to continue to derive, a significant portion of our revenue from sales to international customers. In 2018, 2017 and 2016, 23.1%, 22.7% and 15.8% of our revenue was derived from sales that occurred outside of North America, respectively. In addition, a significant portion of our manufacturing operations is based in Ningbo, China and Taipei, Taiwan.

Trade-related government actions, by China or other countries, that impose barriers or restrictions that would impact our ability to sell or ship products to Huawei or other customers may have a negative impact on our financial condition and results of operations. We cannot predict the actions government entities may take in this context and may be unable to quickly offset or effectively react to government actions that restrict our ability to sell to certain customers or in certain jurisdictions. Government actions that affect our customers' ability to sell products or access critical elements of their supply chains may result in a decreased demand for their products, which may consequently reduce their demand for our products.

Our international revenue and operations are subject to a number of material risks, including:

● difficulties in staffing, managing and supporting operations in more than one country;

● difficulties in enforcing agreements and collecting receivables through foreign legal systems;

● fewer legal protections for intellectual property in foreign jurisdictions;

● foreign and U.S. taxation issues and international trade barriers, including the adoption or expansion of governmental trade tariffs;

● difficulties in obtaining any necessary governmental authorizations for the export of our products to certain foreign jurisdictions;

● fluctuations in foreign economies;

● fluctuations in the value of foreign currencies and interest rates;

● trade and travel restrictions;

● domestic and international economic or political changes, hostilities and other disruptions in regions where we currently operate or may operate in the future;

● difficulties and increased expenses in complying with a variety of U.S. and foreign laws, regulations and trade standards, including the Foreign Corrupt Practices Act; and

● different and changing legal and regulatory requirements in the jurisdictions in which we currently operate or may operate in the future.

Negative developments in any of these factors in China or Taiwan or other countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, difficulties in producing and delivering our products, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business. Although we maintain certain compliance programs throughout the Company, violations of U.S. and foreign laws and regulations may result in criminal or civil sanctions, including material monetary fines, penalties and other costs against us or our employees, and may have a material adverse effect on our business.

47

Our business operations conducted in China and Taiwan are important to our success. A substantial portion of our property, plant and equipment is located in China and Taiwan. We expect to make further investments in China and Taiwan in the future. Therefore, our business, financial condition, results of operations and prospects are subject to economic, political, legal, and social events and developments in China and Taiwan. Factors affecting military, political or economic conditions in China and Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our common shares.

In some instances, we rely on third parties to assist in selling our products, and the failure of those parties to perform as expected could reduce our future revenue.

Although we primarily sell our products through direct sales, we also sell our products to some of our customers through third party sales representatives and distributors. Many of such third parties also market and sell products from our competitors. Our third party sales representatives and distributors may terminate their relationships with us at any time, or with short notice. Our future performance will also depend, in part, on our ability to attract additional third party sales representatives and distributors that will be able to market and support our products effectively, especially in markets in which we have not previously distributed our products. If our current third party sales representatives and distributors fail to perform as expected, our revenue and results of operations could be harmed.

Changes in our effective tax rate may adversely affect our results of operation and our business.

We are subject to income taxes in the U.S. and other foreign jurisdictions, including China and Taiwan. In addition, we are subject to various state taxes in states where we have nexus. We base our tax position on the anticipated nature and conduct of our business and our understanding of the tax laws of the countries and states in which we have assets or conduct activities. Our tax position may be reviewed or challenged by tax authorities. Moreover, the tax laws currently in effect may change, and such changes may have retroactive effect, such as the U.S. tax reform legislation commonly referred to as the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”). We have inter-company arrangements in place providing for administrative and financing services and transfer pricing, which involve a significant degree of judgment and are often subject to close review by tax authorities. The tax authorities may challenge our positions related to these agreements. If the tax authorities successfully challenge our positions, our effective tax rate may increase, adversely affecting our results of operation and our business.

The Tax Act significantly changes how the U.S. taxes corporations. The Tax Act requires complex computations to be performed that were not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the Tax Act and significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S. Treasury Department, the IRS, and other standard-setting bodies could interpret or issue guidance on how provisions of the Tax Act will be applied or otherwise administered that is different from our interpretation. As we interpret any additional guidance, we may make adjustments to amounts that we have recorded that may materially impact our provision for income taxes in the period in which the adjustments are made.

Failure to manage our growth effectively may adversely affect our financial condition and results of operations.

Successful implementation of our business plan in our target markets requires effective planning and management. Production volumes for some of our products are increasing and we have announced plans to increase our production capacity in response to demand for certain of our current and future products, including adding personnel in some of our locations as well as expanding our physical manufacturing facilities. We currently operate facilities in Sugar Land, Texas, Ningbo, China, Taipei, Taiwan, and Duluth, Georgia. We currently manufacture our lasers using a proprietary process and customized equipment located only in our Sugar Land, Texas facility, and it will be costly to duplicate that facility, to scale our laser manufacturing capacity or to mitigate the risks associated with operating a single facility. The challenges of managing our geographically dispersed operations have increased and will continue to increase the demand on our management systems and resources. Moreover, we are continuing to improve our financial and managerial controls, reporting systems and procedures. Any failure to manage our expansion and the resulting demands on our management systems and resources effectively may adversely affect our financial condition and results of operations.

48

Future acquisitions may adversely affect our financial condition and results of operations.

As part of our business strategy, we may pursue acquisitions of companies that we believe could enhance or complement our current product portfolio, augment our technology roadmap or diversify our revenue base. Acquisitions involve numerous risks, any of which could harm our business, including:

● difficulties integrating the acquired business;

● unanticipated costs, capital expenditures or liabilities or changes related to research in progress and product development;

● diversion of financial and management resources from our existing business;

● difficulties integrating the business relationships with suppliers and customers of the acquired business with our existing business relationships;

● risks associated with entering markets in which we have little or no prior experience; and

● potential loss of key employees, particularly those of the acquired organizations.

Acquisitions may also result in the recording of goodwill and other intangible assets subject to potential impairment in the future, adversely affecting our operating results. We may not achieve the anticipated benefits of an acquisition if we fail to evaluate it properly, and we may incur costs in excess of what we anticipate. A failure to evaluate and execute an acquisition appropriately or otherwise adequately address these risks may adversely affect our financial condition and results of operations.

We may be subject to disruptions or failures in information technology systems and network infrastructures that could have a material adverse effect on our business and financial condition.

We rely on the efficient and uninterrupted operation of complex information technology systems and network infrastructures to operate our business. A disruption, infiltration or failure of our information technology systems as a result of software or hardware malfunctions, system implementations or upgrades, computer viruses, third-party security breaches, employee error, theft or misuse, malfeasance, power disruptions, natural disasters or accidents could cause a breach of data security, loss of intellectual property and critical data and the release and misappropriation of sensitive competitive information and partner, customer, and employee personal data. We have experienced ransomware, computer viruses and other forms of cyber terrorism. In past incidents we have been able to recover quickly without material financial impact; however, any of these events could harm our competitive position, result in a loss of customer confidence, cause us to incur significant costs to remedy any damages and ultimately materially adversely affect our business and financial condition.

Our future results of operations may be subject to volatility as a result of exposure to fluctuations in currency exchange rates.

We have significant foreign currency exposure and are affected by fluctuations among the U.S. dollar, the Chinese Renminbi, or RMB, and the New Taiwan dollar, or NT dollar, because a substantial portion of our business is conducted in China and Taiwan. Our sales, raw materials, components and capital expenditures are denominated in U.S. dollars, RMB and NT dollars in varying amounts.

Foreign currency fluctuations may adversely affect our revenue and our costs and expenses, and hence our results of operations. The value of the NT dollar or the RMB against the U.S. dollar and other currencies may fluctuate and be affected by, among other things, changes in political and economic conditions. The RMB currency is no longer being pegged solely to the value of the U.S. dollar. In the long term, the RMB may appreciate or depreciate significantly in value against the U.S. dollar, depending upon the fluctuation of the basket of currencies against which it is currently valued, or it may be permitted to enter into a full float, which may also result in a significant appreciation or depreciation of the RMB against the U.S. dollar. In addition, our currency exchange variations may be magnified by Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.

49

Our sales in Europe are denominated in U.S. dollars and fluctuations in the Euro or our customers’ other local currencies relative to the U.S. dollar may impact our customers and affect our financial performance. If our customers’ local currencies weaken against the U.S. dollar, we may need to lower our prices to remain competitive in our international markets which could have a material adverse effect on our margins. If our customers’ local currencies strengthen against the U.S. dollar and if the local sales prices cannot be raised due to competitive pressures, we will experience a deterioration of our margins.

To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedging transactions may be limited and we may not be able to successfully hedge our exposure.

Natural disasters or other catastrophic events could harm our operations.

Our operations in the U.S., China and Taiwan could be subject to significant risk of natural disasters, including earthquakes, hurricanes, typhoons, flooding and tornadoes, as well as other catastrophic events, such as epidemics, terrorist attacks or wars. For example, our corporate headquarters and wafer fabrication facility in Sugar Land, Texas is located near the Gulf of Mexico, an area that is susceptible to hurricanes. We use a proprietary MBE laser manufacturing process that requires customized equipment, and this process is currently conducted and located solely at our wafer fabrication facility in Sugar Land, Texas, such that a natural disaster, terrorist attack or other catastrophic event that affects that facility would materially harm our operations. In addition, our manufacturing facility in Taipei, Taiwan, is susceptible to typhoons and earthquakes, and our manufacturing facility in Ningbo, China, has from time to time, suffered electrical outages. Any disruption in our manufacturing facilities arising from these and other natural disasters or other catastrophic events could cause significant delays in the production or shipment of our products until we are able to shift production to different facilities or arrange for third parties to manufacture our products. We may not be able to obtain alternate capacity on favorable terms or at all. Our property insurance coverage with respect to natural disaster is limited and is subject to deductible and coverage limits. Such coverage may not be adequate or continue to be available at commercially reasonable rates and terms. The occurrence of any of these circumstances may adversely affect our financial condition and results of operation.

Our business could be negatively impacted as a result of shareholder activism.

In recent years, shareholder activists have become involved in numerous public companies. Shareholder activists frequently propose to involve themselves in the governance, strategic direction, and operations of the Company. We may in the future become subject to such shareholder activity and demands. Such demands may disrupt our business and divert the attention of our management and employees, and any perceived uncertainties as to our future direction resulting from such a situation could result in the loss of potential business opportunities, be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel and business partners, all of which could adversely affect our business. In addition, actions of activist shareholders may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

The unfavorable outcome of any pending or future litigation or administrative action and expenses incurred in connection with litigation could result in financial losses or harm to our business.

We are, and in the future may be, subject to legal actions in the ordinary course of our operations, both domestically and internationally. There can be no assurances as to the favorable outcome of any litigation. In addition, it can be costly to defend litigation and these costs could negatively impact our financial results. As disclosed in “Part II - Item 1. Legal Proceedings,” on August 5, 2017, we and certain of our officers are currently subject to class action litigation related to allegations that we made materially false and misleading statements or failed to disclose material facts. Such litigation includes requests for damages and other relief. As further described in that section, subsequent derivative actions and securities class actions have since been filed.  This litigation and any other such litigation could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

Our success depends on our ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. We have applied for patents in the U.S. and in other foreign countries, some of which have been issued. In addition, we have registered certain trademarks in the U.S. We cannot guarantee that our pending applications will be approved by the applicable governmental authorities. Moreover, our existing and future patents and trademarks may not be sufficiently broad to protect our proprietary rights or may be held invalid or unenforceable in court. A failure to obtain patents or trademark registrations or a successful challenge to our patents and trademark registrations in the U.S. or other foreign countries may limit our ability to protect the intellectual property rights that these patent and trademark registrations intended to cover.

Policing unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken will prevent the misappropriation, unauthorized use or other infringement of our intellectual property rights. Further, we may not be able to effectively protect our intellectual property rights from misappropriation or other infringement in foreign countries where we have not applied for patent protections and where effective patent, trademark, trade secret and other intellectual property laws may be unavailable, or may not protect our proprietary rights as fully as U.S. law. We may seek to secure comparable intellectual property protections in other countries. However, the level of protection afforded by patent and other laws in other countries may not be comparable to that afforded in the U.S.

We also attempt to protect our intellectual property, including our trade secrets and know-how, through the use of trade secret and other intellectual property laws, and contractual provisions. We enter into confidentiality and invention assignment agreements with our employees and independent consultants. We also use non-disclosure agreements with other third parties who may have access to our proprietary technologies and information. Such measures, however, provide only limited protection, and there can be no assurance that our confidentiality and non-disclosure agreements will not be breached, especially after our employees end their employment, and that our trade secrets will not otherwise become known by competitors or that we will have adequate remedies in the event of unauthorized use or disclosure of proprietary information. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products, otherwise obtain and use our intellectual property, or may independently develop similar or equivalent trade secrets or know-how. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed, misappropriated or duplicated, our business, results of operations or financial condition could be materially harmed.

In the future, we may need to take legal actions to prevent third parties from infringing upon or misappropriating our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual property rights and determining their validity and scope could result in significant litigation costs and require significant time and attention from our technical and management personnel, which could significantly harm our business. We may not prevail in such proceedings, and an adverse outcome may adversely impact our competitive advantage or otherwise harm our financial condition and our business.

We may be involved in intellectual property disputes in the future, which could divert management’s attention, cause us to incur significant costs and prevent us from selling or using the challenged technology.

Participants in the markets in which we sell our products have experienced frequent litigation regarding patent and other intellectual property rights. While we have a policy in place that is designed to reduce the risk of infringement of intellectual property rights of others and we have conducted a limited review of other companies’ relevant patents, there can be no assurance that third parties will not assert infringement claims against us. We cannot be certain that our products would not be found infringing on the intellectual property rights of others. Regardless of their merit, responding to such claims can be time consuming, divert management’s attention and resources and may cause us to incur significant expenses. Intellectual property claims against us could force us to do one or more of the following:

● obtain from a third party claiming infringement a license to the relevant technology, which may not be available on reasonable terms, or at all;

51

● stop manufacturing, selling, incorporating or using our products that use the challenged intellectual property;

● pay substantial monetary damages; or

● expend significant resources to redesign the products that use the technology and to develop non-infringing technology.

Any of these actions could result in a substantial reduction in our revenue and could result in losses over an extended period of time.

In any potential intellectual property dispute, our customers could also become the target of litigation. Because we often indemnify our customers for intellectual property claims made against them with respect to our products, any claims against our customers could trigger indemnification claims against us. These obligations could result in substantial expenses such as legal expenses, damages for past infringement or royalties for future use. Any indemnity claim could also adversely affect our relationships with our customers and result in substantial costs to us.

If we fail to obtain the right to use the intellectual property rights of others that are necessary to operate our business, and to protect their intellectual property, our business and results of operations will be adversely affected.

From time to time we may choose to or be required to license technology or intellectual property from third parties in connection with the development of our products. We cannot assure you that third party licenses will be available to us on commercially reasonable terms, if at all. Generally, a license, if granted, would include payments of up-front fees, ongoing royalties or both. These payments or other terms could have a significant adverse impact on our results of operations. Our inability to obtain a necessary third party license required for our product offerings or to develop new products and product enhancements could require us to substitute technology of lower quality or performance standards, or of greater cost, any of which could adversely affect our business. If we are not able to obtain licenses from third parties, if necessary, then we may also be subject to litigation to defend against infringement claims from these third parties. Our competitors may be able to obtain licenses or cross-license their technology on better terms than we can, which could put us at a competitive disadvantage.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected.

Preparing our consolidated financial statements involves a number of complex manual and automated processes, which are dependent upon individual data input or review and require significant management judgment. One or more of these elements may result in errors that may not be detected and could result in a material misstatement of our consolidated financial statements. The Sarbanes-Oxley Act requires, among other things, that as a publicly-traded company we disclose whether our internal control over financial reporting and disclosure controls and procedures are effective.

We have implemented a system of disclosure and internal controls that we believe provide reasonable assurance that we will be able to timely report our financial results and avoid accounting errors or material weaknesses in future periods. However, our internal controls cannot guarantee that no accounting errors exist or that all accounting errors, no matter how immaterial, will be detected because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute assurance that the control system’s objectives will be met. If we are unable to implement and maintain an effective system of disclosure controls and internal control over financial reporting, our ability to accurately and timely report our financial results could be adversely impacted. This could result in late filings of our annual and quarterly reports under the Exchange Act, restatements of our consolidated financial statements, a decline in our stock price, suspension or delisting of our common stock by NASDAQ, or other material adverse effects on our business, reputation, results of operations or financial condition.

Our ability to use our net operating losses and certain other tax attributes may be limited.

As of December 31, 2018, we had U.S. accumulated net operating losses, or NOLs, of approximately $47.4 million, federal and state research and development credits (“R&D credits”) of $6.6 million, interest expense of $1.0 million and foreign tax credits of $4.6 million for U.S. federal income tax purposes. Under Section 382 of the Internal

52

Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change NOLs, tax credits and other pre-change tax attributes to offset its post-change income may be limited. An ownership change is generally defined as a greater than 50% change in equity ownership by value over a 3-year period. Based upon an analysis of our equity ownership, we believe that we have experienced ownership changes; however, we do not believe those limitations result in a material loss of tax benefits. Should we experience additional ownership changes, including upon the issuance of our common stock as a result of any conversion of the Notes into shares of our common stock or otherwise, our NOL carry forwards and tax credits may be further limited.

Our manufacturing operations are subject to environmental regulation that could limit our growth or impose substantial costs, adversely affecting our financial condition and results of operations.

Our properties, operations and products are subject to the environmental laws and regulations of the jurisdictions in which we operate and sell products. These laws and regulations govern, among other things, air emissions, wastewater discharges, the management and disposal of hazardous materials and solid wastes, the contamination of soil and groundwater, employee health and safety and the content, performance, packaging and disposal of products. Our failure to comply with current and future environmental laws and regulations, or the identification of contamination for which we are liable, could subject us to substantial costs, including fines, clean-up costs, natural resource damages, third-party property damages or personal injury claims, administrative, civil or criminal penalties and could result in injunctive relief requiring us to make significant investments to upgrade our facilities, redesign or change our manufacturing processes, redesign our products, or curtail our operations. Liability under environmental, health and safety laws can be joint and several and without regard to fault or negligence. For example, pursuant to environmental laws and regulations, including but not limited to the Comprehensive Environmental Response Compensation and Liability Act, or CERCLA, we may be liable for the full amount of any remediation-related costs at properties we currently own or formerly owned, such as our currently owned Sugar Land, Texas facility, or at properties at which we previously operated, as well as at properties we will own or operate in the future, and properties to which we have sent hazardous substances, whether or not we caused the contamination. Identification of presently unidentified environmental conditions, more vigorous enforcement by a governmental authority, enactment of more stringent legal requirements or other unanticipated events could give rise to adverse publicity, restrict our operations, affect the design or marketability of our products or otherwise cause us to incur material environmental costs, adversely affecting our financial condition and results of operations.

We are exposed to increased expenses and business risk as a result of Restriction on Hazardous Substances, or RoHS directives.

Following the lead of the European Union, or EU, various governmental agencies have either already put into place or are planning to introduce regulations that regulate the permissible levels of hazardous substances in products sold in various regions of the world. For example, the RoHS directive for EU took effect on July 1, 2006. The labeling provisions of similar legislation in China went into effect on March 1, 2007. Consequently, many suppliers of products sold into the EU have required their suppliers to be compliant with the new directive. Many of our customers have adopted this approach and have required our full compliance. Though we have devoted a significant amount of resources and effort in planning and executing our RoHS program, it is possible that some of our products might be incompatible with such regulations. In such events, we could experience the following consequences: loss of revenue, damaged reputation, diversion of resources, monetary penalties, and legal action.

Failure to comply with the U.S. Foreign Corrupt Practices Act could subject us to penalties and other adverse consequences.

We are subject to the U.S. Foreign Corrupt Practices Act which generally prohibits U.S. companies from engaging in bribery or other prohibited payments to foreign officials for the purpose of obtaining or retaining business. In addition, we are required to maintain records that accurately and fairly represent our transactions and have an adequate system of internal accounting controls. Foreign companies, including some that may compete with us, may not be subject to these prohibitions, and therefore may have a competitive advantage over us. If we are not successful in implementing and maintaining adequate preventative measures, we may be responsible for acts of our employees or other agents engaging in such conduct. We could suffer severe penalties and other consequences that may have a material adverse effect on our financial condition and results of operations.

53

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets.

We are subject to export and import control laws, trade regulations and other trade requirements that limit which products we sell and where and to whom we sell our products. Specifically, the Bureau of Industry and Security of the U.S. Department of Commerce is responsible for regulating the export of most commercial items that are so called dual-use goods that may have both commercial and military applications. Our products are classified under Export Control Classification Numbers, or ECCNs, 5A991 and 6A995. Export Control Classification requirements are dependent upon an item’s technical characteristics, the destination, the end-use, the end-user, and other activities of the end-user. Should the regulations applicable to our products change, or the restrictions applicable to countries to which we ship our products change, then the export of our products to such countries could be restricted. As a result, our ability to export or sell our products to certain countries could be restricted, which could adversely affect our business, financial condition and results of operations.

Changes in our products or any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or technologies targeted by such regulations, could result in delayed or decreased sales of our products to existing or potential customers. In such event, our business and results of operations could be adversely affected. For example, in April 2018, Zhongxing Telecommunications Equipment Corporation and ZTE Kangxun Communications Ltd. (collectively “ZTE”) were added to the U.S. Department of Commerce’s Bureau of Industry and Security’s List of Denied Persons, which imposed a seven-year denial of export privileges against ZTE.  However, in July 2018, the denial of export privileged was suspended and ZTE was removed from the list of Denied Persons. Although ZTE is not currently one of our significant customers, such actions against customers or potential customers could adversely affect our business and results of operations.

Rapidly changing standards and regulations could make our products obsolete, which would cause our revenue and results of operations to suffer.

We design our products to conform to regulations established by governments and to standards set by industry standards bodies worldwide, such as the American National Standards Institute, the European Telecommunications Standards Institute, the International Telecommunications Union and the Institute of Electrical and Electronics Engineers, Inc. Various industry organizations are currently considering whether and to what extent to create standards applicable to our products. Because certain of our products are designed to conform to current specific industry standards, if competing or new standards emerge that are preferred by our customers, we would have to make significant expenditures to develop new products. If our customers adopt new or competing industry standards with which our products are not compatible, or the industry groups adopt standards or governments issue regulations with which our products are not compatible, our existing products would become less desirable to our customers and our revenue and results of operations would suffer.

Compliance with regulations related to conflict minerals could increase costs and affect the manufacturing and sale of our products.

Public companies are required to disclose the use of tin, tantalum, tungsten and gold (collectively, “conflict minerals”) mined from the Democratic Republic of the Congo and adjoining countries (the “covered countries”) if a conflict mineral(s) is necessary to the functionality of a product manufactured, or contracted to be manufactured, by the Company. We filed our latest conflict minerals report on Form SD on May 29, 2019. We have previously determined, as part of our compliance efforts, that certain products or components we obtain from our suppliers contain conflict minerals. Based on our Reasonable Country of Origin Inquiry on the source of our conflict minerals for the year ended December 31, 2018, we had reason to believe that certain of such conflict minerals likely originated in covered countries. If we are unable to conclude in the future that all our products are free from conflict minerals originating from covered countries, this could have a negative impact on our business, reputation and/or results of operations. We may also encounter challenges to satisfy customers who require that our products be certified as conflict free, which could place us at a competitive disadvantage if we are unable to substantiate such a claim. Compliance with these rules could also affect the sourcing and availability of some of the minerals used in the manufacture of products or components we obtain from our suppliers, including our ability to obtain products or components in sufficient quantities and/or at competitive prices. Certain of our customers are requiring additional information from us regarding the origin of our raw materials, and complying with these customer requirements may cause us to incur additional costs, such as costs related to determining

54

the origin of any minerals used in our products. Our supply chain is complex and we may be unable to verify the origins for all metals used in our products. We may also encounter challenges with our customers and stockholders if we are unable to certify that our products are conflict free.

Some provisions of our named executive officers’ agreements regarding change of control or separation of service contain obligations for us to make separation payments to them upon their termination.

Certain provisions contained in our employment agreements with our named executive officers regarding change of control or separation of service may obligate us to make lump sum severance payments and related payments upon the termination of their employment with us, other than such executive officer’s resignation without good reason or our termination of their employment as a result of their disability or for cause. In the event we are required to make these separation payments, it could have a material adverse effect on our results of operations for the fiscal period in which such payments are made.

Risks Related to Our Operations in China

Our business operations conducted in China are critical to our success. A total of $143.1 million, $122.3 million and $81.1 million or 53.6%, 32.0% and 31.1%, of our revenue in the years ended December 31, 2018, 2017 and 2016 was attributable to our product manufactured at our plant in China, respectively. Additionally, a substantial portion of our property, plant and equipment, 36.8%, 29.9% and 23.0% as of December 31, 2018, 2017 and 2016, was located in China, respectively. We expect to make further investments in China in the foreseeable future. Therefore, our business, financial condition, results of operations and prospects are to a significant degree subject to economic, political, legal, and social events and developments in China. 

Adverse changes in economic and political policies in China, or Chinese laws or regulations could have a material adverse effect on business conditions and the overall economic growth of China, which could adversely affect our business.

The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Despite reforms, the government continues to exercise significant control over China’s economic growth by way of the allocation of resources, control over foreign currency-denominated obligations and monetary policy and provision of preferential treatment to particular industries or companies.

In addition, the laws, regulations and legal requirements in China, including the laws that apply to foreign-invested enterprises, or FIEs, are subject to frequent changes. The interpretation and enforcement of such laws is uncertain. Protections of intellectual property rights and confidentiality in China may not be as effective as in the U.S. or other countries or regions with more developed legal systems. Any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention. Any adverse changes to these laws, regulations and legal requirements or their interpretation or enforcement could have a material adverse effect on our business.

Furthermore, while China’s economy has experienced rapid growth in the past 20 years, growth has been uneven across different regions, among various economic sectors and over time. China has also in the past and may in the future experience economic downturns due to, for example, government austerity measures, changes in government policies relating to capital spending, limitations placed on the ability of commercial banks to make loans, reduced levels of exports and international trade, inflation, lack of financial liquidity, stock market volatility and global economic conditions. Any of these developments could contribute to a decline in business and consumer spending in addition to other adverse market conditions, which could adversely affect our business.

The termination and expiration or unavailability of our preferential tax treatments in China may have a material adverse effect on our operating results.

Prior to January 1, 2008, entities established in China were generally subject to a 30% state and 3% local enterprise income tax rate. In accordance with the China Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, effective through December 31, 2007, our China subsidiary enjoyed preferential income tax rates.

55

Effective January 1, 2008, the China Enterprise Income Tax Law, or the EIT law, imposes a single uniform income tax rate of 25% on all Chinese enterprises, including FIEs, and eliminates or modifies most of the tax exemptions, reductions and preferential treatment available under the previous tax laws and regulations. As a result, our China subsidiary may be subject to the uniform income tax rate of 25% unless we are able to qualify for preferential status. Since calendar year 2012, we have qualified for a preferential 15% tax rate that is available for state-encouraged new high technology enterprises. In order to retain this preferential tax rate, we must meet certain operating conditions, satisfy certain product requirements, meet certain headcount requirements and maintain certain levels of research expenditures. In November 2017, we received approval from the Chinese government to extend this preferential tax treatment for an additional three years, ending November 2020. If we fail to continue to qualify for this preferential rate in the future, we may incur higher tax rates on our income in China. Any future increase in the enterprise income tax rate applicable to us or the expiration or other limitation of preferential tax rates available to us could increase our tax liabilities and reduce our net income.

The turnover of direct labor in manufacturing industries in China is high, which could adversely affect our production, shipments and results of operations.

Employee turnover of direct labor in the manufacturing sector in China is extremely high and retention of such personnel is a challenge to companies located in or with operations in China. Although direct labor costs do not represent a high proportion of our overall manufacturing costs, direct labor is required for the manufacture of our products. If our direct labor turnover rates are higher than we expect, or we otherwise fail to adequately manage our direct labor turnover rates, then our results of operations could be adversely affected.

Chinese regulation of loans to and direct investment by offshore holding companies in China entities may delay or prevent us from making loans or additional capital contributions to our China subsidiary.

Any loans that we wish to make to our China subsidiary are subject to Chinese regulations and approvals. For example, any loans to our China subsidiary to finance their activities cannot exceed statutory limits, must be registered with State Administration of Foreign Exchange, or SAFE, or its local counterpart, and must be approved by the relevant government authorities. Any capital contributions to our China subsidiary must be approved by the Ministry of Commerce or its local counterpart. In addition, under Circular 142, our China subsidiary, as a FIE, may not be able to convert our capital contributions to them into RMB for equity investments or acquisitions in China.

We cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all, with respect to our future loans or capital contributions to our China subsidiary. If we fail to receive such registrations or approvals, our ability to capitalize our China subsidiary may be negatively affected, which could materially and adversely affect our liquidity and ability to fund and expand our business.

Our China subsidiary is subject to Chinese labor laws and regulations, and Chinese labor laws may increase our operating costs in China.

Chinese labor laws and regulations provide certain protections for our employees located in China, and changes to those labor laws and regulations may increase our costs and reduce our flexibility. The China Labor Contract Law, which went into effect in 2008, together with its implementing rules, provides increased rights to Chinese employees compared to prior employment laws in China. Under the rules under the China Labor Contract Law, the probation period varies depending on contract terms and the employment contract can only be terminated during the probation period for cause upon three days’ notice. Additionally, an employer may not be able to terminate a contract during the probation period on the grounds of a material change of circumstances or a mass layoff. The law also has specific provisions on conditions when an employer has to sign an employment contract with open-ended terms. If an employer fails to enter into an open-ended contract in certain circumstances, the employer must pay the employee twice their monthly wage beginning from the time the employer should have executed an open-ended contract. Additionally, an employer must pay severance for nearly all terminations, including when an employer decides not to renew a fixed-term contract. Any further changes to these laws may increase our costs and reduce our flexibility.

An increase in our labor costs in China may adversely affect our business and our profitability.

A significant portion of our workforce is located in China. Labor costs in China have been increasing recently due to labor unrest, strikes and changes in employment laws. If labor costs in China continue to increase, our costs will

56

increase. If we are not able to pass these increases on to our customers, our business, profitability and results of operations may be adversely affected.

We may have difficulty establishing and maintaining adequate management and financial controls over our China operations.

Businesses in China have historically not adopted a western style of management and financial reporting concepts and practices, which includes strong corporate governance, internal controls and computer, financial and other control systems. Moreover, familiarity with U.S. GAAP principles and reporting procedures is less common in China. As a consequence, we may have difficulty finding accounting personnel experienced with U.S. GAAP, and we may have difficulty training and integrating our China-based accounting staff with our U.S.-based finance organization. As a result of these factors, we may experience difficulty in establishing and maintaining management and financial controls over our China operations. These difficulties include collecting financial data and preparing financial statements, books of account and corporate records and instituting business practices that meet U.S. public-company reporting requirements. We may, in turn, experience difficulties in implementing and maintaining adequate internal controls as required under Section 404 of the Sarbanes-Oxley Act.

Risks Related to Our Common Stock

Our stock price has been and is likely to be volatile.

The market price of our common stock has been and is likely to be subject to wide fluctuations in response to, among other things, the risk factors described in this section of this Quarterly Report on Form 10-Q, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us. For example, announcements made by competitors regarding factors influencing their business may cause fluctuations in the valuation of companies throughout our industry, including fluctuations in the valuation of our stock.

Furthermore, the stock markets have experienced price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions, such as recessions, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

In the past, many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We have been and may become the target of this type of litigation in the future. For example, on August 3, 2017 we provided guidance for the third quarter of 2017, and on August 4, 2017 the market price of our stock decreased significantly. As disclosed in “Part II - Item 1. Legal Proceedings,” on August 5, 2017, a class action lawsuit was filed against us and two of our officers. The complaint in this matter alleges that we made materially false and misleading statements or failed to disclose material facts and requests damages and other relief. On August 7, 2018, a derivative class action lawsuit was filed against our chief executive officer, chief financial officer and board of directors. The allegations are substantially similar to those under the August 5, 2017 lawsuit. On October 1, 2018, another class action lawsuit was filed in the U.S. District Court for the Southern District of Texas against us and two of our officers. The complaint in this matter alleges that we made materially false and misleading statements or failed to disclose material facts and a related action was filed on October 10, 2018. These lawsuits and any other such litigation could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

We have incurred and will continue to incur significant increased expenses and administrative burdens as a public company, which could have a material adverse effect on our operations and financial results.

We face increased legal, accounting, administrative and other costs and expenses as a public company that we did not incur as a private company, and greater expenditures may be necessary in the future with the advent of new laws, regulations and stock exchange listing requirements pertaining to public companies. These increased costs will require us to divert a significant amount of money that we could otherwise use to expand our business and achieve our strategic objectives. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Public Company Accounting Oversight Board and the NASDAQ Global Market, impose additional reporting and other obligations on public companies. Compliance with public company

57

requirements has increased our costs and made some activities more time-consuming. For example, we have created board committees and adopted internal controls and disclosure controls and procedures. In addition, we have incurred and will continue to incur additional expenses associated with our SEC reporting requirements. Furthermore, if we identify any issues in complying with those requirements (for example, if we or our auditors identify a material weakness or significant deficiency in our internal control over financial reporting), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect us, our reputation or investor perceptions of us. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase our costs. Legal, accounting, administrative and other costs and expenses may increase in the future as we continue to incur both increased external audit fees as well as additional spending to ensure continued regulatory compliance.

We currently do not intend to pay dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We currently do not plan to declare or pay dividends on shares of our common stock in the foreseeable future. Consequently, your only opportunity to achieve a return on any shares of our common stock that you may acquire will be if the market price of our common stock appreciates and you sell your shares at a profit. There is no guarantee that the price of our common stock in the market will ever exceed the price that you pay.

Our charter documents, stock incentive plans and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

Our amended and restated certificate of incorporation and our amended and restated bylaws and our stock incentive plans contain provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:

● providing for a classified board of directors with staggered, three-year terms;

● not providing for cumulative voting in the election of directors;

● authorizing our board of directors to issue, without stockholder approval, preferred stock rights senior to those of common stock;

● prohibiting stockholder action by written consent;

● limiting the persons who may call special meetings of stockholders;

● requiring advance notification of stockholder nominations and proposals; and

● change of control provisions in our stock incentive plans, and the individual stock option agreements, which provide that a change of control may accelerate the vesting of the stock options and equity awards issued under such plans.

In addition, we are governed by the provisions of Section 203 of the Delaware General Corporate Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from engaging in certain business combinations without the approval of substantially all of our stockholders for a certain period of time.

These and other provisions in our amended and restated certificate of incorporation, our amended and restated bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.

58

If research analysts do not publish research about our business or if they issue unfavorable commentary or downgrade our common stock, our stock price and trading volume could decline.

The trading market for our common stock depends on the research and reports that research analysts publish about us and our business. The price of our common stock could decline if one or more research analysts downgrade our common stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business. If one or more of the research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price or trading volume to decline.

Appendix 1

Description, Risks Disclosure Statement and Advance Notice of Financial Derivatives

(Taishin International Bank hereby requests the Customer to carefully read this description, risks disclosure statement and advance notice)

"Financial Transaction" or "transaction" defined in this Agreement refers to Financial Transactions made from time to time between the Bank and the Customer, including but not limited to Spot or Forward transactions of Currency,  Currency exchange, Currency Options, Forward Rate Agreement,  Interest Rate Swap,  Cross Currency Swap, asset swap, Structured Products, Credit Derivatives,  Equity Derivatives,  Commodity Derivatives, and all other financial derivative transaction contracts, with individual transaction types as follows. See product description or Transaction Confirmation of individual transactions for other matters not covered. Following gains and losses situational analysis for Financial Transactions (results of gains and losses situational analysis does not guarantee future performance) assumes that:

a.    The Customer has not requested premature termination or change of conditions since the trade date, and

b.    There are no credit risks at the Bank during product investment period.

1.    Forward

Transactions that specify a future Business Day as the Settlement Day on the trade date, which deal with substantive settlement or balance settlement at a specific price and specified amount.

Example 1: The Customer buys in (or sells out) agreed notional amount at an agreed price on Forward Settlement Day.

Settlement situation:

The Customer buys in (or sells out) agreed notional amount in {Currency 1}, and sells out (or buys in) agreed notional amount in [Currency 2] on Forward Settlement Day

Gains and losses analysis: [relatively poor]

In the event of Spot rate less (or greater) than Forward rate on product Settlement Day, then absolute value of the "notional amount x (Spot rate - Forward rate)" valued in [Currency 2] is Customer's potential settlement losses from the transaction. If currencies exchange is required for contract transactions calculated, then the result might be subject to exchange rate fluctuation, which will result in further gains or losses.

Gains and losses analysis: [relatively good]

In the event of Spot rate greater (or less) than Forward rate on product Settlement Day, then absolute value of the result of "notional amount x (Spot rate - Forward rate)" valued in [Currency 2] is Customer's potential settlement gains from the transaction. If currencies exchange is required for contract transactions calculated, then the result might be subject to exchange rate fluctuation, which will result in further gains or losses.

Example 2:  The Customer conducts a non-deliverable Forward transaction that buys (or sells) an agreed notional amount on the Forward settlement date

Settlement situation:

The Customer receives or pays "(fixing (or Forward) rate - Forward (or fixing) rate) x agreed notional amount/fixing rate" in [Currency 1] based on the fixing rate on the Forward settlement date

Gains and losses analysis:  [relatively poor]

Assuming that the fixing rate on the product Fixing Date is less (greater) than the Forward rate, the absolute value of the result of "notional amount x (fixing rate - Forward rate)/fixing rate" valued in [Currency 1] shall be the settlement losses of the Customer from the transaction.

Gains and losses analysis:  [relatively good]

Assuming that the fixing rate on the product Fixing Date is greater (less) than the Forward rate, the absolute value of the result of "notional amount x (fixing rate - Forward rate)/fixing rate" valued in [Currency 1] shall be the settlement gains of the Customer from the transaction.

Potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

If the market price on the settlement date is not in favor of the Customer's settlement, the Customer may suffer a settlement loss at the end of the period with an amount that has no upper limit.

2.    Currency Swap

Transactions that buy (or sell) a specified amount of foreign exchange in the Spot market, and at the same time sell (or buy) equivalent amount of foreign exchanges in the Forward market.

Example: A transaction that buys (sells) and sells (buys) the same amount of a Currency at the same time, but on different settlement dates. The Customer conducts a transaction that buys/sells (or sells/buys) an agreed notional amount in [Currency 1] in exchange for [Currency 2] in the Spot market and the Forward market at the same time

Settlement situation:

The Customer buys (or sells) an agreed notional amount in [Currency 1], and sells (or buys) the amount of "agreed notional amount x exchange rate at the beginning of the period" in [Currency 2].on the Spot settlement date

Gains and losses analysis: [relatively poor]

The cost of the Customer's debit and credit in [Currency 1] and [Currency 2] is the Forward rate point of the swap rates at the end and the beginning of the period.

Without consideration of the swap rate at the beginning of the period, assuming that the Spot rate on the final swap date is less (or greater) than the final swap rate, the absolute value of the result of "notional amount x (Spot rate - final swap rate)" valued in [Currency 2] shall be the Customer's losses of market price from the transaction.

Gains and losses analysis: [relatively good]

The cost of the Customer's debit and credit in [Currency 1] and [Currency 2] is the Forward rate point of the swap rates at the end and the beginning of the period.

Without consideration of the swap rate at the beginning of the period, assuming that the Spot rate on the final swap date is greater (or less) than the final swap rate, the absolute value of the result of "notional amount x (Spot rate - final swap rate)" valued in [Currency 2] shall be the Customer's gains of market price from the transaction.

Potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

◎    The cost of the Customer's debit and credit in [Currency 1] and [Currency 2] is the Forward rate point of the swap rates at the end and the beginning of the period. Without consideration of the swap rate at the beginning of the period, if the market price on the final swap date is not in favor of the Customer's settlement, the Customer may suffer a loss of market price at the end of the period with an amount that has no upper limit.

3.   Interest Rate Swap

Transactions that use different interest rate indexes of a single Currency for purpose of swap to exchange a specified amount of interest or interest differential on a regular basis over a period of time. The types of Interest Rate Swap may be fixed-for-floating Interest Rate Swap, fixed-for-fixed Interest Rate Swap, and floating-for-floating Interest Rate Swap.

Example: The Customer conducts an Interest Rate Swap transaction in which the Customer pays a fixed (or floating) interest rate of the notional amount, and receives a floating (or fixed) interest rate on a regular basis over a certain period of time

Settlement situation:

The Customer pays (or receives) "an agreed notional amount x fixed rate x number of days based on the fixed interest rate", and receives (or pays) "the notional amount x floating rate x number of days based on floating interest rate" on the settlement date of each period; both parties swap the interest rate at regular intervals during the agreed period

Gains and losses analysis: [relatively poor]

Assuming that the Customer regularly pays a fixed (or floating) interest rate and regularly receives a floating (or fixed) interest rate from the first period (inclusive) to the last period (inclusive) of the first year, if the paid interest rate is greater than the received interest rate, then the analysis of differential gains and losses of the transaction shall be the cumulative losses (before tax) of the Customer in that year: (the paid interest rate - the received interest rate)%.

Gains and losses analysis: [relatively good]

Assuming that the Customer regularly pays a fixed (or floating) interest rate and regularly receives a floating (or fixed) interest rate from the first period (inclusive) to the last period (inclusive) of the first year, if the received interest rate is greater than the paid interest rate, then the analysis of differential gains and losses of the transaction shall be the cumulative gains (before tax) of the Customer in that year: (the received interest rate - the paid interest rate)%.

Potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

If any paid interest rate of the Customer is greater than the received interest rate during the period of the contract, the Customer may suffer a settlement loss in that period with an amount that has no upper limit.

4.    Cross Currency Swap

Transactions that exchange a specified amount of principal and interest between different currencies over a period of time, and may be an actual delivery or a balance settlement.

Example: The Customer conducts a Cross Currency Swap transaction in which the Customer buys/sells (or sells/buys) a specified amount of [Currency 1] in exchange for [Currency 2] over a period of time

Settlement situation:

[Notional amount 1] is the agreed notional amount of [Currency 1]

[Notional amount 2] is the [Currency 2] notional amount of [notional amount 1] x swap rate at the beginning of the period

[Notional amount 3] is the [Currency 2] notional amount of [notional amount 1] x swap rate at the end of the period

The Customer buys (or sells) [notional amount 1] and sells (or buys) [notional amount 2] on the Spot settlement date, and sells (or buys) [notional amount 1] and buys (or sells) [notional amount 3] on the Forward settlement date;

And the Customer regularly pays (or receives) a [Currency 1] interest of [notional amount 1] x [Currency 1] interest rate x number of days based on [Currency 1] interest rate, and the Customer regularly receives (or pays) a [Currency 2] interest of [notional amount 2] x [Currency 2] interest rate x number of days based on [Currency 2] interest rate

Gains and losses analysis of Interest Rate Swap

From the first period (inclusive) to the last period (inclusive) of the first year, the Customer regularly pays (or receives) [Currency 1] interest rate, and regularly receives (or pays) [Currency 2] interest rate.

Principal swap gains and losses analysis 1:

The cost of the Customer's debit and credit in [Currency 1] and [Currency 2] is the Interest Rate Swap.

Without consideration of the swap rate at the beginning of the period, assuming that the Spot rate on the final swap date is less (or greater) than the final swap rate, the absolute value of the result of "[notional amount 1] x (Spot rate - final swap rate)" valued in [Currency 2] shall be the Customer's losses of market price from the transaction.

Principal swap gains and losses analysis 2:

The cost of the Customer's debit and credit in [Currency 1] and [Currency 2] is the Interest Rate Swap.

Without consideration of the swap rate at the beginning of the period, assuming that the Spot rate on the final swap date is greater (or less) than the final swap rate, the absolute value of the result of "[notional amount 1] x (Spot rate - final swap rate)" valued in [Currency 2] shall be the Customer's gains of market price from the transaction.

Potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

◎    Interest Rate Swap: If any paid interest rate of the Customer is greater than the received interest rate during the period of the contract, the Customer may suffer a settlement loss in that period with an amount that has no upper limit.

◎    Principal swap: Without consideration of the swap rate at the beginning of the period, if the Spot rate on the final swap date is not in favor of the Customer's settlement, the Customer may suffer a loss of market price in that period with an amount that has no upper limit.

5.    Commodity Swap

Transactions that use commodity price as the underlying subject of a swap to exchange a specified quantity of fixed and floating prices on a regular basis during the agreed period.

Example: The Customer conducts a swap transaction in which the Customer acts as the payer of fixed (floating) prices and the payee of floating (fixed) prices

Settlement situation:

The Customer pays (or receives) "the specified quantity x fixed price", and receives (or pays) "the specified quantity x floating price" on the settlement date

Gains and losses analysis: [relatively poor]

Assuming that the fixed price is greater (or less) than the floating price, the absolute value of the result of "the specified quantity x (fixed price - floating price)" shall be the Customer's settlement losses from the transaction.

Gains and losses analysis: [relatively good]

Assuming that the fixed price is less (or greater) than the floating price, the absolute value of the result of "the specified quantity x (fixed price - floating price)" shall be the Customer's settlement gains from the transaction.

Potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

If the paid price of the Customer is greater than the received price during the period of the contract, the Customer may suffer a settlement loss in that period with an amount that has no upper limit.

6.    Option

The agreement that the Seller of the Option promises that the Buyer of the Option has the right (but not the obligation) to buy/sell an underlying asset from/to him when exercising the Option (including American, European, Bermuda, etc.), and an actual delivery or a balance settlement may be made when the agreement is performed.

Maximum potential losses and the greatest possible risks for the Customer are (Maximum potential losses):

© If this Agreement is terminated before maturity by the Customer, the commodity shall be calculated based on the market price, and in addition to being unable to settle on the basis of the settlement amount calculation, the Customer may also suffer losses of premature termination and even bear an unlimited loss in extreme cases.

All these derivatives above have their own corresponding commodity risk levels. The evaluation principles of commodity attribute of derivatives include these factors, such as fluctuation range, class of underlying assets, product days, financial derivatives risk index, and commodity complexity. Comprehensively evaluating and confirming the degree of commodity risk of these financial derivatives, which is divided into 1-6 levels from low to high:

Definition of product risk level:

1.     The First Level is very conservative: the linked slight-volatility risk market, the market value or the profit and loss of the transaction are rarely influenced by the risk factors such as market changes and changes of policy and rule of law.

2.     The Second Level is conservative: the linked low-volatility risk market, the market value or the profit and loss of the transaction are rarely influenced by the risk factors such as market changes and changes of policy and rule of law.

3.     The Third Level is steady: the linked low-volatility to middle-volatility risk market, the market value or the profit and loss of the transaction are slightly influenced by the risk factors such as market changes and changes of policy and rule of law.

4.     The Fourth Level is growth: the linked middle-volatility to high-volatility risk market, the market value or the profit and loss of the transaction are moderately influenced by the risk factors such as market changes and changes of policy and rule of law.

5.     The Fifth Level is positive: the linked high-volatility risk market, the market value or the profit and loss of the transaction are greatly influenced by the risk factors such as market changes and changes of policy and rule of law, and product structure may be diversified.

6.     The Sixth Level is very positive: the linked extremely high-volatility risk market, the market value or the profit and loss of the transaction are significantly influenced by the risk factors such as market changes and changes of policy and rule of law, and product structure may be diversified or has a leverage structure, and the commodity complexity is high.

The Customer should take the financial commodity risk into full consideration and refer to the Bank’s financial commodity risk level if he deals with financial derivatives not for the purpose of hedging. If the risk level exceeds the risk rating made by the Bank, the Customer should assess the operation situation and financial operating of the company prudently and understand the relevant risk of financial commodity, and has consulted or consider there is no need to consult expert advisors other than the Bank to fully understand before makes a trade decision.

This risk discloses the risks of all exchange rates, interest rates, stock prices, credits, indexes, futures, Options, structured commodities and all other financial derivatives that can’t be disclosed in declaration and disclosure statement. Because of these risks, the Customer must understand the nature of the transactions that will be made and the risk levels that will be undertaken before conducts a transaction. The Customer should also consider carefully in terms of his operating experience, purposes, financial conditions and other points, and have a clear understanding of the nature of the transaction and the legal relationship of the relevant contracts signed, and the nature and level of the risks that may arise after the transaction, to consider deliberately whether such transactions are suitable for conducting.

General Risk (This risk potentially exists regardless of the type of the Financial Transaction)

1.     Premature termination: If the Financial Transaction is not approved by the Bank, the Customer may not, in principle, terminate it early before the agreed Maturity Date. If the Bank agrees to terminate a contract in advance, the costs, losses or service charges incurred should be borne by the Customer, and the costs or losses include the costs incurred by writing off the hedge position of the commodity. The Customer may get a lower commodity yield than its pre-determined one, and even a negative yield.

2.     The intervention of the supervision organization: If the right of the Bank to deal with the open position is deprived or restricted due to its supervision organization or any other reasons, the Customer will be affected. Under such circumstances, the Customer may be asked to reduce the uncovered position with the Bank or unwind the position.

3.     Electronic trading: Undertake transactions on an electronic trading system, which may be different from undertaking transactions on other electronic trading systems. If the Customer undertakes transactions on an electronic system, he will be exposed to risks associated with the system including the failure of hardware and software. Failure of the system may result in the trade demand of the Customer is not executed according to the instructions, or even not executed at all.

4.     Non-agent transactions: The Customer and the Bank conduct a transaction with each other all on their own behalf, and the Bank and the Customer are each other’ s counterparty in terms of the transactions conducted.

5.     Market risk: The Customer may suffer a loss when the market quotation is detrimental to the Customer’s position. If the market quotation changes drastically, the loss of the Customer’s close position may exceed the originally expected one. The Bank only conducts a transaction when the market price of the stop-loss (limit) order or reservation order breaks through the specified price. These reservation orders may result in a failure of making a deal exactly at the price specified by the Customer due to the changes of the market quotation, and further cause a large (small) loss (profit) than the originally expected one. In extreme cases, domestic and foreign markets or institutions may stop trading so that the position of the Customer can’t be closed out, thus may lead to a larger (smaller) loss (profit).

6.     Credit risk: The Customer must bear the credit risk of the Bank. The Customer must also bear the credit risk of the credit Reference Entity if the transaction conducted by the Customer is a credit derivative.

7.     Tax risk: The product traded by the Customer may generate taxes. Also, Tax Act or relevant specifications, interpretations of any responsible institutions may generate risks such as adding or changing taxes.

8.     Risk of potential conflict of interest: The Bank will conduct a transaction as a client or agent in the market where products are traded, including but not limited to buying and selling products. This may affect the price of the product at any point of time (whether it is a positive or negative impact). In addition, the Bank is the clearing institution of the product, and the interest of the Bank may conflict with the interest of the Customer within the above range.

9.     The acquisition and extraction risk of the loss margin: If the contract document signed by the Customer with the Bank has a loss margin or Mark-to-Market Loss clause, when the market situation is detrimental to the Customer and cause the mark-to-market loss to exceed the loss limit, the Customer should provide the loss margin of the differential section between the mark-to-market and the loss limit according to the notice of the Bank, to cover all losses arising from the calculation of the transaction at the market price during the remaining period of the transaction conducted by the Customer. The mark-to-market profit or loss of the financial derivatives is affected by factors such as the market price of the underlying asset.  When the market price is detrimental to the transaction of the Customer, the mark-to-market loss of the transaction is likely to be much larger than expected. When the adverse situation of the market is aggravated and/or the remaining period of the transaction conducted by the Customer is long, the loss margin mentioned above that need to be provided may be very large or much greater than expected. The Customer should cover the large amount of loss margin in a short time, but the market value of the other financial assets of the Customer may slump at this time. The ability of the Customer to cover the loss margin now may be far below the time when the market condition is normal, and the liquidity risk of fund procurement may be generated. The Customer understands that failure to fulfill the requirement for providing the loss margin, the transaction will be handled according to the contract documents or terminated early without the consent of the Customer, and the relevant losses and expenses will be undertaken by the Customer. The Customer may take tons of losses.

10.   Maximum risk exposure risk: The Customer should carefully assess in advance the maximum amount of risk exposure (or calculate the maximum amount of risk exposure generated by other undue contracts of the same type), and the appropriate hedge position of the relevant Currency holdings or expected cash outflows. If a financial derivative is not for hedging, its maximum possible loss amount may be infinite, and if it is a structured commodity that has a multiplier clause, the trade loss will enlarge due to the multiplier effect when the the market price is not favorable to the Customer. For the financial derivatives traded for the purpose of hedging, if the transaction amount is larger than the real demand, the excess part will bear the risk of no coverage by the substantial position.

11.   Terminating the transaction early: The Customer terminates the transaction early before the contract expires, and if the market price is not conducive to the transaction of the Customer, the Customer may bear

huge transaction losses. The derivatives with a long day will take higher risks. And if the market price is not conducive to the transaction of the Customer, the Customer will bear higher transaction losses of early termination.

12.   Derivative transactions may be related to, or based on, interest exchange rates, currencies, securities, commodities and other underlying assets. Under certain market conditions, the Customer may suffer relevant losses or gain considerable interests; the result may be detrimental or beneficial to the Customer and will lead to huge losses or high profits in terms of the highly leveraged of the quota or the transaction. The Customer should bear the losses caused by all risks (the amount may be fairly large). And the Bank is not responsible for any risks arising from the quota or the transaction. Therefore, the Customer should consider carefully his financial conditions, experience, targets and other relevant conditions to determine whether these transactions are suitable for conducting. The Customer must also make sure that he has been fully aware of the nature of any quotas and transactions, the contractual relationship that he will get into, and the nature and degree of the risk taken by him. This instruction cannot disclose all the risks and other important notices of the derivative transaction. The Bank recommends that the Customer obtains independent legal and investment opinions before conducting any quotas or transactions.

13.   The Customer may request the Bank to provide a description of the risks of the transaction when the transactional contract is established, and start to make a transaction request to the Bank in the way specified by the Bank after the Customer agrees to understand the risks of the transaction. Once the transaction is established, all profits and losses will be fully borne by the Customer, and the investor cannot require the Bank to assume any responsibilities for insufficient risk perception or other reasons.

Structured Product Risk

1.     Structured Product refers to the Structured Product transaction that combines fixed income products with financial derivatives (most of which are Options and swap contracts). It can link to a  wide range of underlying, including transactional contracts derived from interest rate, exchange rate, stock price, index, commodity, credit event or other interests and their combinations. Structured Product is not a general savings, but an investment. Its profit and loss are influenced by many factors, such as the market price of the underlying asset, the condition of the product, the mechanism of exiting the market early, or the occurrence of the agreed credit event. In the situation where certain conditions are met, the profit of Structured Product may be higher than that of the common simple deposit rate; otherwise, it may reduce and erode the investment principal. The Bank doesn’t promise to return all investment principal when the agreement is terminated before maturity, and modest capital preservation at maturity is depending on the condition set up.

2.     “Principal protected Structured Product”  refers to the condition where the Customer uses all or part of the fixed income generated by the original capital of investment for paying or exchanging financial derivatives (Options and swap contracts) when conducting a Structured Product transaction. If the trend of the underlying asset or product condition of the financial derivatives (Options and swap contracts) meets the expectation of the Customer, the remuneration of the product condition can be obtained; on the contrary, if the trend of the underlying asset or product condition of the financial derivatives (Options and swap contracts) does not meet the expectation of the Customer, the maximum probable loss is achieving nothing in the case where the Customer always owns the product prior to the date due and the credit risk has not occurred in the Bank.  “Non-principal protected Structured Product” refers to the condition where the Customer uses all or part of the fixed income generated by the original capital of investment or the principal for paying or exchanging financial derivatives (Options and swap contracts) when conducting a Structured Product transaction. If the trend of underlying asset or product condition of the financial derivatives (Options and swap contracts) meets the expectation of the Customer, the remuneration of the product condition can

be obtained; however, if the trend of underlying asset or product condition of the financial derivatives (Options and swap contracts) does not meet the expectation of the Customer, it is probably that the risk side of the financial derivative (Options and swap contracts) transaction is executed, and the Customer should transfer the matured principal to an agreed Currency or security or other agreed assets, or draw the amount of money lower than the original capital of investment (that is there is a loss of the original capital of investment) according to the agreed conversion condition of the original capital of investment and expired product condition.

3.     Structured Product transaction has the characteristics of the financial derivative (Options and swap contracts) (such as exchange rate, interest rate, commodity, credit, stock price or stock price index) transaction that engages in single or multiple underlying assets, and involves many risks which will probably be great. Therefore, the Customer should take account of his financial situation and risk taking ability before conducting this transaction. The following items should be paid attention to during the transaction:

(1)   The five main factors that affect the price of the financial derivatives (Options and swap contracts) are as follows: the volatility of single or multiple underlying assets, the market price or the Forward market price curve of the underlying asset, the product condition, the expiration time of the product, and the existence of the mechanism for the product to exit the market early. The changes of the price of the financial derivatives are not necessarily beneficial to the Customer when the changes of one or two above items are beneficial to the Customer. The investor should comprehensively assess the positive or negative effects caused by the various factors to make an appropriate trade decision.

(2)For financial derivatives (Options and swap contracts), it is necessary to further assess their maximum possible loss according to the individual product conditions when the market changes are detrimental to them. The probable maximum loss may include the loss of the original capital of investment if trading “non-principal protected Structured Product”.

(3)   When the position of the financial derivatives (Options and swap contracts) is detrimental to the Customer, the Customer uses the Spot or Forward Option in the market or the swap contract to avoid the market risk. But the risk is not necessarily smaller than that of buying back or selling the financial derivatives directly in the market, depending on the product conditions traded.

(4)   The only way for financial derivatives (Options and swap contracts) to be liquidated in advance should be buying or selling the financial derivatives traded before directly in the market, rather than trading in the Spot or Forward Option or swap contract market.

(5)   The execution of the order of financial derivatives (Options and swap contracts) depends on the market situation, and the transaction may not be concluded at a predetermined price when the market fluctuates drastically.

4.     The Customer understands the market related to the investment underlying of a "Structured Product" may be affected by laws, regulations or policies, which may cause the market to stop transactions, terminate transactions, close down or other risks.

5.     The degree of the risks faced by the Customer varies with the designs and conditions of "Structured Products". The main risks include but are not limited to the principal conversion risk, market interest rate risk, investment underlying applicability risk, principle loss risk, liquidity risk, reinvestment risk regarding acceleration of maturity, midway termination risk, credit risk, taxation risk, exchange risk, country risk, legal risk, product conditions change risk, etc. The Customer may require the Bank to provide instructions on the risks of a transaction before the establishment of the transaction contract. The Customer agrees to make a transaction request to the Bank in the manner prescribed by the Bank after understanding the transaction risks. Once the transaction is established, the Customer shall be

responsible for all profits and losses, and shall not require the Bank to assume any responsibility for insufficient risk perception or other reasons.

6.     In principle, the Customer shall not terminate the contract or withdraw the money in advance before the agreed Maturity Date of the "Structured Product", unless approved by the Bank. If the Bank agrees with the Customer to terminate the contract or withdraw the money in advance, the resulting costs, losses or fees generated by the Bank shall be borne by the Customer. The costs or losses include the costs incurred by the Bank in writing off the hedge position of the product. The Customer may get a return rate lower than the preset rate of the product, or even a negative return rate (i.e. damaging investment principal).

7.     For any other Financial Transactions, the Customer must clearly understand all relevant legal requirements (including investment restrictions), and the Customer shall consider the legal, taxation, and accounting influence imposed by the Financial Transaction. When appropriate, the Customer shall also consider consulting with appropriate consultants on the products to invest and the special environment to get assisted in understanding the risks involved. If the Customer is a financial adviser or agent, various risks mentioned above shall also be assessed based on the Customer or his/her relevant circumstances.

8.     When the Customer and the Bank conduct a "Structured Product" transaction, the Customer shall understand that the Bank is a contractual object for the Customer, and is by no means a financial adviser or a trustee for its trust.

9.     Warnings on investing in Structured Products:

(1)   This product is a complex financial product and must be explained by an expert before investing. If investors cannot fully understand this product, do not invest.

(2)   This product is not a deposit but an investment which is not covered by deposit insurance.

(3)   The investor shall read product descriptions and risk disclosure statements before investing, and shall understand and judge for himself/herself, and be responsible for his/her own profits and losses.

(4)   This product is an investment-oriented product. The investor shall bear the market risk of this product and the credit risk of Taishin Bank by himself/herself.

(5)   The investor shall not sign or seal relevant documents without clearly understanding the product descriptions, contract terms and the whole document content.

(6)   The investor's midway terminating the contract may result in the recoverable money lower than the investment principal.

(7)   The maximum possible loss is the entire investment principal.

(8)   The degree of the risks faced by the investor varies with the designs and conditions of Structured Products. For cash settlement, there may risks of part or all interest, principal loss or other losses; for non-cash settlement, the principal may convert to underlying assets as agreed, and probably the investor must bear the credit risks of the Bank and the issuer of the underlying assets.

(9)   The factors that affect the price changes of financial derivatives are extremely complex. The risks disclosed by the Bank only cover the major part of the risks. It may not be able to expatiate on the transaction risks and factors affecting market quotations. Therefore, the investor shall fully

understand the nature of the Structured Product, and related financial, accounting, taxation or legal issues before transaction, and assess his/her own financial status and risk tolerance, and then decide whether to invest.

Option Transaction Risk

1.     The risk of selling Options is generally higher than the risk of buying Options: although the Customer could exclusively obtain the Premium when selling Options, he/she may bear a loss much bigger than the Premium: the obligation of the Customer's selling Options is unlimited, and with the rise and fall of the prices of underlying assets (foreign exchanges, stocks, interest rates, raw materials, etc.), the Customer's loss may be unlimited, while the profit is only limited to the Premium. The Customer must bear the risk that the Buyer exercises the Option when selling an Option. At that time, the Customer is obligated to settle in cash, or buy, sell or deliver relevant equities. Involved risk may be reduced if the Customer holds a corresponding relevant equity or underlying asset, or another Option "covered Option". In addition, as an Option Seller, the Customer must understand that he/she needs to bear market price fluctuations and other risks. When there are losses according to market assessment, the Customer should provide a deposit to the Bank as agreed. If the deposit provided is much larger than expected, there may be s liquidity risk with regard to fund transferring. If the Customer fails to fulfill the obligation to provide a deposit, so that the Bank terminates the transaction in advance, then the Customer may bear huge losses.

The market also has novel Options with different risk patterns. When the Customer undertakes an Option transaction, he/she shall first understand his/her rights and obligations, evaluate his/her risk tolerance, and then make the transaction. For example, for European Knock-in Options, the rights and obligations of the Option Buyer and Seller come into effect at the prices-comparing point when the market price knocks effective conditions, and then risks arise as stated above; for American Knock-out Options, there is no knock events after the transaction is undertaken and before the prices-comparing point, and the rights and obligations of this American Knock-out Option's Buyer and Seller are the same as general Options, but if the market price has knocked failure conditions at any time, the rights and the obligations will become invalid in advance; for digital Options, the risk of the Option Seller will rise and fall as the prices of underlying assets (foreign exchanges, stocks, interest rates, raw materials, etc.) change, and the loss will be a fixed amount, the profits will be only limited to the Premium. Furthermore, if the Customer undertakes a structured transaction with a complex pattern (covering multiple groups of Options with different Maturity Dates), for example: the product condition is to leave in advance when periodic profits accumulate to the target price, with the rise and fall of the prices of underlying assets (foreign exchanges, stocks, interest rates, raw materials, etc.), the rights and obligations of the Customer may terminate in advance. If the rights and obligations don't terminate in advance, the Customer's losses may be unlimited. Also please notice that the amount of money regarding the Customer's rights and the amount regarding the obligations do not necessarily have to be equal. The amount regarding the Customer's obligations may be multiple of the amount regarding the rights (leverage operation), resulting in the loss multiple of the profit. When the market is not in favor of the calculation direction of the delivery amount for the investor, the delivery amount may be amplified due to the leverage factor, and the investor will face delivery losses and suffer significant losses. In the worst case, the Customer's loss may have no upper limit. After the transaction day, the marked to market value will be affected by various market factors, depending on the underlying (foreign exchanges, stocks, interest rates, raw materials, etc.). For example, if the Customer undertakes a structured foreign exchange transaction with a complex pattern, he/she will be affected by market factors such as interest rates, exchange rates, credit spreads and related Currency fluctuations. When the relevant market factors are not favor of the calculation direction of the delivery amount for the investor, the transaction loss will be amplified due to the leverage factor, and the market price of the product will drop rapidly, probably causing huge transaction loss.

As the financial market changes, the Customer will be exposed to more and more single or complex structured Option transactions. The content above does not cover all kinds of Option transactions and

corresponding risks, nor does it mean the Option transactions not listed here involve no risks. Therefore, the Customer must judge for himself/herself the Option to be transacted, the transaction and corresponding risks. The Bank does not forecast or guarantee any market conditions.

2.     Exchange and swap risk: Profits or losses incurred in contract transactions calculated in Foreign Currency (regardless of whether the transaction is conducted in his/her own jurisdiction or elsewhere), the unit Currency to be exchanged will likely be affected by exchange rate fluctuations. If the investor conducts a transaction with a Foreign Currency, and chooses to exchange the delivery Currency for local Currency when delivery, he/she may encounter profits or losses due to exchange rate fluctuations.

3.     Structured policy: It may not be effective to set certain instructions (such as "stop-loss orders" or "stop-limit orders" permitted by local laws) to control losses to a certain extent. Because the market may not allow clinching a deal at a preset price, and it may also make relevant orders fail to be exercised. In addition, when using a combination position policy (such as Spot or Forward transactions) to hedge against the risk of financial derivative transactions, the risk is not necessarily less than the risk of buying or selling the financial derivative directly in the market, and vice versa.

4.     Liquidity risk, transaction suspension or restriction, and price relationship: market conditions (such as Currency cannot be circulated) and/or some market regulation (such as transactions are suspended for any Currency due to the price restriction, government intervention or interruption of the trading system) may lead to difficulties in or inability to completing/complete transactions or closing/close positions. If such a situation occurs after the Customer sells a Option, the risk of loss to the Customer may increase. The normal price relationship between related assets and futures or Options may not exist. For example, under extreme market conditions, Spot contracts related to stock Options are regulated by price restrictions, and only unilateral Buyer or Seller market remains, so the appeared transaction price is actually not a true transaction price, but the price is still used to execute the Option's rights and obligations when the Option is mature. Therefore, it's hard to judge what a "fair price" is for the Customer due to a lack of relevant reference asset prices. When the Customer undertakes a structured transaction with a complex pattern which lacks liquidity due to its combination of many financial derivatives, if he/she terminates the contract in advance, there may be a spread between the actual transaction price and the original asset value of the product. As a result, the Customer may suffer a loss with regard to midway termination when he/she sells the product before maturity. And even the Customer must hold the product until its maturity once the market completely loses liquidity. Long term structured transactions with complex patterns have high risks. When the market price is not in favor of transactions for the Customer, he/she will bear big transaction losses with regard to early termination. When the Customer applies for midway termination of the contract, the value of the product will be calculated based on the market price on the termination day, not the calculation description of the original delivery amount. The calculation of the price regarding midway termination involves complex derivative calculations and risks. If the market price is not in favor of the transaction for the Customer, he/she will bear huge transaction losses. In the worst case, there is no upper limit to the possible loss.

Swap Transaction Risk

1.     Swap means that the Customer agrees to undertake a single or a series of transaction(s) that swap(s) an underlying asset for another within a certain period in the future. The swappable underlying assets include foreign exchanges, interest rates, credit defaults, and raw materials, etc. The Customer will face the price risk arising from changes in the prices of the market underlying assets after undertaking such transactions. With the passage of time, this swap transaction may result in a loss without an upper limit due to a drastically changing market.

2.     Liquidity risk, transaction suspension or restriction: market conditions (such as Currency, credit, target bonds cannot be circulated) and/or some market regulation (such as transactions are suspended for any

Currency, raw material or rate underlying due to the price restriction, government intervention or interruption of the trading system) may lead to difficulties in or inability to completing/complete transactions or closing/close positions. If such a situation occurs after the Customer undertakes a swap transaction, the risk of loss to the Customer may increase.

Other Financial Transaction risks

Spot,  Forward,  Forward Rate Agreement,  Interest Rate Swap,  Currency Swap,  Cross Currency Swap,  Credit Derivatives,  Equity Derivatives, ECB/CB asset swap, Commodity Derivatives and other financial product transactions are also involved with or based on interest rate, exchange rate, Currency, securities, products, credit and/or other assets. Content above does not cover all kinds of Financial Transactions and their risks, and it does not mean that there are no risks for the uncovered Financial Transactions. Therefore, the Customer shall still, in its sole discretion, decide the Financial Transactions to be made and assess their risks.

Risks of RMB financial derivatives (Structured Product included)

When making the transaction with the RMB financial derivatives involved, in addition to the underlying asset risks and the various secondary-risk portfolios from the financial derivatives, the Customer might also be at the following risks when dealing with this kind of transaction since now the RMB is still subject to the relevant regulations of the Republic of China and Mainland China:

1.     The Customer shall fully understand the risk that the transaction will also be affected by other factors in addition to the market when involved with RMB financial derivatives and shall fully understand the valuation results:

(1)    In addition to the effect of general market fluctuation factors, the transaction involved with RMB financial derivatives is also subject to the law or policy changes in Mainland China or other regions; or the supply and demand of RMB funds in the market may be affected due to the limitation of the RMB clearing service, leading to a greater fluctuation range of the exchange rate, interest rate or other related underlying asset, which will affect the profit and loss on the transaction gains, as well as the market price assessment.

(2)When the Customer makes the transaction involved with RMB, the attainability, liquidity and transferability of RMB might be affected due to the RMB clearing service, non-public market transactions or special circumstances, which then will further cause the greater transaction risks or the valuation of loss.

2.     The Customer shall fully understand that the buy/sell or clearing and settlement of RMB will be subject to the relevant regulations:

(1)    Different from the other foreign currencies, the buy/sell limit of RMB shall be in accordance with the relevant regulations regarding the Foreign Currency transaction. In the event that the Customer receives and pays in RMB for the financial derivatives, the buy/sell limit of RMB, time period and related procedures shall be aware of.

(2)   The RMB assets and debts originally possessed by the Customer or his/her receipt and payment obligations arisen from the transactions might be under the influence of the supply and demand of the RMB funds in the market due to the subject to law or policy changes or the limitation of the RMB clearing service, which then will affect the clearing and settlement of the relevant transactions. Although the Bank has conducted the follow-up work to the already accepted RMB cases, it shall dedicate itself to search for other solutions and methods. However, if necessary, it is possible for the Bank to use another Currency for clearing and settlement according to the market exchange rate at that time.

3.     The Customer shall fully understand that the RMB exchange rate and other price may apply to the underlying assets in different markets, which will affect the clearing and settlement of the transactions, as well as market price assessment result:

RMB exchange rate is currently categorized into the RMB exchange rate in the mainland China and the RMB exchange rate out of the mainland China, and there might also be many exchange rate indicators for the latter with their respective transaction markets. Different exchange rate indicators might derive the interest rate or other related underlying assets that applies to different circumstances. Aforementioned indicators might be more similar or dissimilar due to the market liquidity and other factors, which affects the price of the applicable underlying assets derived from them. The financial derivatives, clearing and settlement, and the market price assessment of different exchange rates or underlying assets are based on the different situation, each item is in accordance with its respective content in the agreed contract. The Customer shall fully understand the applicable exchange rate, interest rate, and the price of related underlying assets for the transaction, and shall, in its sole discretion, evaluate the derived transaction risks and losses before making the transaction.

The description and risk disclosure statement and advance notice for the above financial derivatives did not cover all the risks and related considerations for all financial product transactions, and it does not mean that there are no risks for the uncovered financial product transactions included in the Customer's transactions. Therefore, if the Customer is not fully aware of all risks of this type of transaction and has not decided the applicability in its sole discretion, they shall not make this type of transaction, and is recommended to actually complete financial planning and risk assessment before the transaction, in order to avoid unbearable losses arisen from it.

The Customer has carefully read through this  "Description, Risks Disclosure Statement and Advance Notice of Financial Derivatives", and confirms to have fully understand general risks for engaging in transactions described here, and agrees to assume risks of related investment and be liable for losses resulted from transactions. The Customer hereby declares that he/her has already acquired a copy of this document.

76.       For the bills, orders, and letters of credit provided by the Customer under this contract, if the payment is received before the expiration date of the corresponding loan, the Customer agrees that the Bank can directly offset the loan in advance.

77.       If the Customer undertakes the transaction of outward bills in the Bank but the payment is refused abroad, or if payment isn’t received when the export collection expires, or if there are other foreign buyers failing to pay as agreed, the Customer is willing to pay off immediately without any conditions.

Interim Financial Statements

The unaudited condensed consolidated financial statements of the Company as of June 30, 2019 and December 31, 2018 and for the three and six months ended June 30, 2019 and June 30, 2018, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim information and with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X 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 required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2018. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for doubtful accounts, inventory reserve, product warranty costs, share-based compensation expense, estimated useful lives of property and equipment, and taxes.

Note 2.   Significant Accounting Policies

There have been no changes in the Company’s significant accounting policies for the three and six months ended June 30, 2019, as compared to the significant accounting policies described in its 2018 Annual Report, except as described below.

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted in 2019 

On February 25, 2016, the FASB released Accounting Standards Update (ASU) No. 2016-02, Leases, to complete its project to overhaul lease accounting. The ASU codifies ASC 842, Leases, which will replace the guidance in ASC 840. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this ASU on January 1, 2019 without any impact to beginning retained earnings. Upon adoption of the new lease standard, the Company elected the package of practical expedients which allowed it to carry forward the historical lease classification on existing leases at adoption. In addition, the Company elected the short-term lease recognition exemption for all leases that qualify. The Company also elected the practical expedient to not separate lease and non-lease components for all of its leases. The Company has implemented internal controls to enable the presentation of financial information on adoption. The standard has a material impact on the Company’s consolidated balance sheet, but did not have an impact in its consolidated income statements. The most significant effects of adopting the new standard relate to the recognition of new ROU assets and lease liabilities on its balance sheet for its Taiwan branch. See Note 4, "Operating Leases" for additional information on the required disclosures related to the impact of adopting this standard.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The Company adopted this ASU on January 1, 2019 with no impact on its consolidated financial statements.

Recent Accounting Pronouncements Yet to be Adopted

In June 2016, the FASB issued ASU 2016-13 Financial Instruments - Credit Losses, Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Based on the composition of the Company’s investment portfolio, current market conditions, and historical credit loss activity, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial statements.

Revenue Recognition

Revenue Recognition

Note 3. Revenue Recognition

The adoption of Topic 606 represents a change in accounting principle that will provide financial statement readers with enhanced revenue recognition disclosures. In accordance with Topic 606, revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Certain customers may receive cash and/or non-cash incentives, which are accounted for as variable consideration. To achieve this core principle, the Company applies the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when or as the Company satisfies a performance obligation. The Company generally satisfies performance obligations at a point in time. Revenue is recognized based on the transaction price at the time the related performance obligation is satisfied by transferring a promised product or service to a customer.

Disaggregation of Revenue

Revenue is classified based on the location of where the product is manufactured. For additional information on the disaggregated revenues by geographical region, see Note 17, "Geographic Information.”

Revenue is also classified by major product category and is presented below (in thousands):

Operating Leases

Operating Leases

Operating Leases

Note 4. Operating Leases

The Company leases space under non-cancelable operating leases for manufacturing facilities, research and development offices and certain storage facilities and apartments. These leases do not contain contingent rent provisions. The Company also leases certain machinery, office equipment and a vehicle under operating leases. Many of its leases include both lease (e.g. fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g. common-area or other maintenance costs) which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Several of the leases include one or more options to renew which have been assessed and either includes or excludes from the calculation of the lease liability of the ROU asset based on management’s intentions and individual fact patterns. Several warehouses and apartments have non-cancelable lease terms of less than one-year and therefore, the Company has elected the practical expedient to exclude these short-term leases from its ROU asset and lease liabilities.

As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Based on the applicable lease terms and current economic environment, the Company applies a location approach for determining the incremental borrowing rate.

The Components of lease expense were as follows for the periods indicated (in thousands):

Earnings Per Share

Note 6.   Earnings Per Share

Basic net income (loss) per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units and senior convertible notes outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and diluted earnings per share are the same.

The following table sets forth the computation of the basic and diluted net income (loss) per share for the periods indicated (in thousands, except per share amounts):

The carrying value amounts of accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate fair value because of the short-term maturity of these instruments. The carrying value amounts of debt approximate fair value due to the short-term nature of the debt since it renews frequently at current interest rates. The Company believes that the interest rates in effect at each period end represent the current market rates for similar borrowings.

The Notes will mature on March 15, 2024, unless earlier repurchased, redeemed or converted in accordance with their terms.

If a make-whole fundamental change (as defined in the Indenture) occurs, and in connection with certain other conversions before March 15, 2022, the Company will in certain circumstances increase the conversion rate for a specified period of time.

Initially there are no guarantors of the Notes, but the Notes will be fully and unconditionally guaranteed, on a senior, unsecured basis by certain of the Company’s future domestic subsidiaries.  The Notes are the Company’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.  The Note Guarantee (as defined in the Indenture) of each future guarantor, if any, will be such guarantor’s senior, unsecured obligations and are equal in right of payment with existing and future senior, unsecured indebtedness, senior in right of payment to such future guarantor’s existing and future indebtedness that is expressly subordinated to the Notes and effectively subordinated to such future guarantor’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness.

Holders may require the Company to repurchase their Notes upon the occurrence of a fundamental change (as defined in the Indenture) at a cash purchase price equal to the principal amount thereof plus accrued and unpaid interest, if any.

The Company may not redeem the Notes prior to March 15, 2022.  On or after March 15, 2022, the Company may redeem for cash all or part of the Notes if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such redemption notice.  The redemption price is equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.  In addition, calling any Note for redemption will constitute a “make-whole fundamental change” with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption.

The Indenture contains covenants that limit the Company’s ability and the ability of our subsidiaries to, among other things: (i) incur or guarantee additional indebtedness or issue disqualified stock; and (ii) create or incur liens.

The Company incurred approximately $4.1 million in transaction costs in connection with the issuance of the Notes. These costs were recognized as a reduction of the carrying amount of the Notes utilizing the effective interest method and are being amortized over the term of the notes.

The following table sets forth interest expense information related to the Notes (in thousands):

The Company issued stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) to employees, consultants and non-employee directors. Stock option awards generally vest over a four year period and have a maximum term of ten years. Stock options under these plans have been granted with an exercise price equal to the fair market value on the date of the grant. Nonqualified and Incentive Stock Options, RSAs and RSUs may be granted from these plans. Prior to the Company’s initial public offering in September 2013, the fair market value of the Company’s stock had been historically determined by the board of directors and from time to time with the assistance of third party valuation specialists.

Stock Options

Options have been granted to the Company’s employees under the five incentive plans and generally become exercisable as to 25% of the shares on the first anniversary date following the date of grant and 12.5% on a semi-annual basis thereafter. All options expire ten years after the date of grant.

Income Taxes

Note 16.  Income Taxes

The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. The Company’s quarterly tax provision, and its quarterly estimate of its annual effective tax rate, are subject to significant variation due to several factors, including variability in accurately predicting its pre-tax income and loss and the mix of jurisdictions to which they relate, tax law developments and relative changes in permanent tax benefits or expenses.

The Company’s effective tax rate for the three months ended June 30, 2019 and 2018 was (22.0%) and 22.2%, respectively. For the three months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the three months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. global intangible low-taxed income ("GILTI").

The Company’s effective tax rate for the six months ended June 30, 2019 and 2018 was (20.6%) and 11.4% respectively. For the six months ended June 30, 2019, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, and tax benefits related to research and development. For the six months ended June 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development and recognition of the U.S. GILTI.

As of June 30, 2019, the Company has accumulated undistributed earnings generated by its foreign subsidiaries of approximately $23 million. Because $23 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the Tax Cut of Jobs Act of 2017 (the “Tax Act”), any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of its foreign investments would generally be limited to foreign and state taxes. The Company intends, however, to indefinitely reinvest these earnings and expects future U.S. cash generation to be sufficient to meet future U.S. cash needs.

Litigation

Overview

From time to time, the Company may be subject to legal proceedings and litigation arising in the ordinary course of business, including, but not limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. The Company records a loss provision when it believes it is both probable that a liability has been incurred and the amount can be reasonably estimated. Unless otherwise disclosed, the Company is unable to estimate the possible loss or range of loss for the legal proceeding described below.

Except for the lawsuits described below, the Company believes that there are no claims or actions pending or threatened against it, the ultimate disposition of which would have a material adverse effect on it.

Class Action and Shareholder Derivative Litigation

On August 5, 2017, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against the Company and two of its officers in Mona Abouzied v. Applied Optoelectronics, Inc., Chih-Hsiang (Thompson) Lin, and Stefan J. Murry, et al., Case No. 4:17-cv-02399. The complaint in this matter seeks class action status on behalf of the Company’s shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, its chief executive officer, and its chief financial officer, arising out of its announcement on August 3, 2017 that “we see softer than expected demand for our 40G solutions with one of our large customers that will offset the sequential growth and increased demand we expect in 100G.” A second, related action was filed by Plaintiff Chad Ludwig on August 16, 2017 (Case No. 4:17-cv-02512) in the Southern District of Texas. The two cases were consolidated before Judge Vanessa D. Gilmore. On January 22, 2018, the court appointed Lawrence Rougier as Lead Plaintiff and Levi & Korinsky LLP as Lead Counsel. Lead Plaintiff filed an amended consolidated class action complaint on March 6, 2018. The amended complaint requests unspecified damages and other relief. The Company filed a motion to dismiss on April 4, 2018, which was denied on March 28, 2019.  The Company disputes the allegations, and intends to continue to vigorously defend against these claims.  On May 15, 2019, Lead Plaintiff filed a motion for leave to amend the consolidated class action complaint for the purpose of adding named Plaintiffs Richard Hamilton, Kenneth X. Luthy, Roy H. Cetlin, and John Kugel (together with Lead Plaintiff Lawrence Rougier, “Plaintiffs”) to the case. The court granted the motion on May 16, 2019. The substantive allegations in the Plaintiffs’ operative second amended consolidated class action complaint remain unchanged. On May 28, 2019, Plaintiffs filed a motion seeking to certify the case as a class action pursuant to Federal Rule of Civil Procedure 23 and seeking appointment of Plaintiffs as class representatives and Levi & Korsinsky as class counsel. On July 12, 2019, the Company filed a response in opposition to the motion for class certification. The deadline for Plaintiffs’ reply brief is August 26, 2019. The case is currently in the early stages of discovery, and fact discovery is scheduled to be completed by June 1, 2020..  At this early stage, we are not yet able to determine the likelihood of loss, if any, arising from this matter.

On August 7, 2018, Plaintiff Lei Jin filed a purported derivative action on behalf of nominal defendant Applied Optoelectronics, Inc. in the U.S. District Court for the Southern District of Texas against the Company’s chief executive officer, chief financial officer and board of directors (Case No. 4:18-cv-02713).  This case was consolidated with a later filed derivative lawsuit filed by Plaintiff Yiu Kwong Ng in the U.S. District Court for the Southern District of Texas (Case No. 4:18-cv-4751). The allegations in the consolidated derivative complaints are substantially similar to those underlying the Abouzied securities class action and the Taneja securities class action discussed below. The consolidated derivative action is stayed pending a ruling on defendants’ forthcoming motion to dismiss in the Taneja securities class action.

On October 1, 2018, a lawsuit was filed in the U.S. District Court for the Southern District of Texas against the Company and two of its officers in Gaurav Taneja v. Applied Optoelectronics, Inc., Thompson Lin, and Stefan Murry, Case No. 4:18-cv-03544. The complaint in this matter seeks class action status on behalf of the Company’s shareholders, alleging violations of Sections 10(b) and 20(a) of the Exchange Act against the Company, its chief executive officer, and its chief financial officer, arising out of its announcement on September 28, 2018 that it was revising its third quarter revenue guidance due to “an issue with a small percentage of 25G lasers within a specific customer environment.” This case was consolidated with two identical cases styled Davin Pokoik v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry, Case No. 4:18-cv-3722 and Stephen McGrath v. Applied Optoelectronics, Inc., Chih-Hsiang Lin, and Stefan J. Murry.  Mark Naglich was appointed as Lead Plaintiff on the consolidated matter on January 4, 2019.  Lead Plaintiff filed an amended consolidated complaint on March 5, 2019, and the Company filed a motion to dismiss the amended consolidated complaint on May 6, 2019. On July 5, 2019, Plaintiff filed a response in opposition to the motion to dismiss. The deadline for the Company’s reply brief in support of the motion to dismiss is August 5, 2019. The Company disputes the allegations and intends to vigorously contest the matter.

Books and Records Request

On April 10, 2019, stockholder David Bono filed a complaint in the Delaware Court of Chancery against the Company seeking to inspect certain corporate books and records pursuant to Section 220 of the Delaware General Corporation Law.  The lawsuit is styled David Bono v. Applied Optoelectronics, Inc., Case No. 2019-0275 (Del. Ch. 2019).  The complaint does not seek damages but seeks the plaintiff’s costs and expenses, including attorneys’ fees, as well as the requested books and records.  On July 5, 2019, by agreement of the parties, the Vice Chancellor issued an order staying the case to allow the parties to seek resolution of the dispute outside of litigation. A joint status report is due to the Court by September 3, 2019.

Interim Financial Statements

Interim Financial Statements

The unaudited condensed consolidated financial statements of the Company as of June 30, 2019 and December 31, 2018 and for the three and six months ended June 30, 2019 and June 30, 2018, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim information and with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X 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 required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2018. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for doubtful accounts, inventory reserve, product warranty costs, share-based compensation expense, estimated useful lives of property and equipment, and taxes.

Revenue Recognition

The adoption of Topic 606 represents a change in accounting principle that will provide financial statement readers with enhanced revenue recognition disclosures. In accordance with Topic 606, revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. Certain customers may receive cash and/or non-cash incentives, which are accounted for as variable consideration. To achieve this core principle, the Company applies the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when or as the Company satisfies a performance obligation. The Company generally satisfies performance obligations at a point in time. Revenue is recognized based on the transaction price at the time the related performance obligation is satisfied by transferring a promised product or service to a customer.

Disaggregation of Revenue

Revenue is classified based on the location of where the product is manufactured. For additional information on the disaggregated revenues by geographical region, see Note 17, "Geographic Information.”

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Recent Accounting Pronouncements Adopted in 2019 

On February 25, 2016, the FASB released Accounting Standards Update (ASU) No. 2016-02, Leases, to complete its project to overhaul lease accounting. The ASU codifies ASC 842, Leases, which will replace the guidance in ASC 840. The new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this ASU on January 1, 2019 without any impact to beginning retained earnings. Upon adoption of the new lease standard, the Company elected the package of practical expedients which allowed it to carry forward the historical lease classification on existing leases at adoption. In addition, the Company elected the short-term lease recognition exemption for all leases that qualify. The Company also elected the practical expedient to not separate lease and non-lease components for all of its leases. The Company has implemented internal controls to enable the presentation of financial information on adoption. The standard has a material impact on the Company’s consolidated balance sheet, but did not have an impact in its consolidated income statements. The most significant effects of adopting the new standard relate to the recognition of new ROU assets and lease liabilities on its balance sheet for its Taiwan branch. See Note 4, "Operating Leases" for additional information on the required disclosures related to the impact of adopting this standard.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The Company adopted this ASU on January 1, 2019 with no impact on its consolidated financial statements.

Recent Accounting Pronouncements Yet to be Adopted

In June 2016, the FASB issued ASU 2016-13 Financial Instruments - Credit Losses, Measurement of Credit Losses on Financial Instruments, which changes the way entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net earnings. The new standard is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Based on the composition of the Company’s investment portfolio, current market conditions, and historical credit loss activity, the adoption of ASU 2016-13 is not expected to have a material impact on its consolidated financial statements.

Earnings Per Share

Basic net income (loss) per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units and senior convertible notes outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and diluted earnings per share are the same.
