Basis of Presentation

The condensed consolidated financial data at December 31, 2020 are derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2021 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K.  All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2021.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current condensed consolidated financial statement presentation. E

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.  During the three months ended March 31, 2021 and 2020, we paid no dividends on our Common Stock.

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:

	Three Months Ended

NOTE 5 – Income Tax Provision

The table below sets forth information related to our income tax expense:

	Three Months Ended
	March 31,
	2021			2020
Domestic pre-tax income	$	7,069		$	5,268
Foreign pre-tax income	$	42,918		$	19,688
Income tax provision	$	9,434		$	4,556
Effective tax rate		18.9	%		18.3	%
Impact of tax holidays on tax expense	$	(582	)	$	(1,074	)
Earnings per share impact of tax holidays:
Basic	$	0.01		$	0.02
Diluted	$	0.01		$	0.02

 The increase in the effective tax rate for the three months ended March 31, 2021 when compared to the three months ended March 31, 2020, is primarily attributable to a change in pre-tax earnings during the comparable periods. 

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of certain European and Asian subsidiaries.  Any future distributions of foreign earnings will not be subject to additional U.S. income tax, but may be subject to non-U.S. withholding taxes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2012, or for the 2015 tax year. We are no longer subject to China income tax examinations by tax authorities for tax years before 2010. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2015. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from currently pending tax audits. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in interest expense. As of March 31, 2021, the gross amount of unrecognized tax benefits was approximately $43.9 million.   

-11-

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

NOTE 6 – Share-Based Compensation

For the three months ended March 31, 2021, we recognized stock option expense of approximately $0.02 million.  This stock option expense is related to stock options granted by Savitech Corporation (“Savitech”) in Savitech stock to their employees.  We acquired a controlling interest in Savitech in 2020.  The remainder of our share-based compensation expense was related to share grants. Approximately $0.8 million of cash proceeds were received from stock option exercises during the three months ended March 31, 2021. The table below sets forth the line items where share-based compensation expense was recorded:

Total share-based compensation expense	$	6,122	$	4,693

Share Grants – Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period. All new grants are granted under the Company’s 2013 Equity Incentive Plan, and there will be no additional share grants under the 2001 Omnibus Equity Incentive Plan. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant, and compensation expense is recognized on a straight-line basis over the requisite four-year service period. 

Performance stock units (“PSUs”) are measured based on the fair market value of the underlying stock on the date of grant, and compensation expense is recognized over the three-year performance period, with adjustments made to the expense to recognize the probable payout percentage. PSUs will vest upon the Company achieving a cumulative 3-year non-GAAP operating income target for the applicable periods.

As of March 31, 2021, total unrecognized share-based compensation expense related to share grants was approximately $52.2 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.2 years.          

NOTE 7 – Segment Information and Net Sales

Segment Reporting. For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various manufacturing and distribution facilities. We aggregate our products because the products are similar and have similar economic characteristics, use similar production processes and share similar customer type. Our primary operations include operations in Asia, North America and Europe. No customer accounted for 10% or more of our net sales or outstanding accounts receivable at any point in the periods presented in this Quarterly Report.

Disaggregation of Net Sales. We disaggregate net sales with customers into direct sales and distribution sales (“Distributors”) and by geographic area. Direct sales customers consist of those customers using our product in their manufacturing process, and Distributors are those customers who resell our products to third parties. We deliver our products to customers around the world for use in consumer electronics, computing, communications, industrial and automotive markets. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months.

The tables below set forth net sales for the Company disaggregated into geographic locations based on shipment and by type (direct sales or Distributor) for the three months ended March 31, 2021 and 2020:

NOTE 8 – Debt

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $205.5 million. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured, uncommitted and contain no restrictive covenants.  These credit facilities bear interest at LIBOR or similar indices plus a specified margin.  Interest payments are due monthly on outstanding amounts under the credit lines. The unused and available credit under the various facilities as of March 31, 2021, was approximately $127.9  million, net of a $67.6  million advanced under our foreign credit lines and $0.5 million credit used for import and export guarantee. In connection with our Asia credit facilities $54.8 million of cash

-13-

deposits have been restricted in support of a corresponding loan amount. During April 2021 $50.0 million of the restricted cash was released from all contractual restrictions, as the applicable loans were repaid in full.

Long-term debt

The Company maintains a long-term credit facility (“Credit Agreement”) consisting of a term loan with a current balance of $218.0 million and a $150.0 million revolving senior credit facility.  The Company used a portion of the proceeds available under the term commitment and the revolving senior credit facility to finance the Company’s acquisition of Lite-On Semiconductor Corporation. The Credit Agreement contains certain financial and non-financial covenants, including, but not limited to, a maximum Consolidated Leverage Ratio, a minimum Consolidated Fixed Charge Coverage Ratio, and restrictions on liens, indebtedness, investments, fundamental changes, dispositions, and restricted payments (including dividends and share repurchases).  Furthermore, under the Credit Agreement, restricted payments, including dividends and share repurchases, are permitted in certain circumstances, including while the pro forma Consolidated Leverage Ratio is, both before and after giving effect to any such restricted payment, at least 0.25 to 1.00 less than the maximum permitted under the Credit Agreement.  In addition to the credit facilities described above, our 51% owned subsidiary, ERIS Technology Corporation (“ERIS”), has short-term debt of $13.3 million and long-term debt of $30.0 million from local Taiwan banks.  The ERIS debt matures in various periods from 2021 through 2033.  

Borrowings outstanding as of March 31, 2021 and December 31, 2020, are set forth in the table below:

	March 31,			December 31,				Current Amount

NOTE 9 – Commitments and Contingencies

Purchase commitments – As of March 31, 2021, we had approximately $58.6 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia.  As of March 31, 2021, we also had a commitment to purchase approximately $40.4 million of wafers to be used in our manufacturing process during 2021 and 2022.  

Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of March 31, 2021, the underfunded liability for this defined benefit plan was approximately $25.1 million.  An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $37.4 million based on a GBP: USD exchange rate of 1.4:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.8 million based on a GBP: USD exchange rate of 1.4:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to

-14-

eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million (approximately $0.3 million based on GBP: USD exchange rate oat 1.4:1) in annual installments to cover expenses.

Contingencies – From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.  Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.  The Company is not currently a party to any pending litigation that the Company considers material.

Note 10 – Derivative Financial Instruments

We use derivative instruments to manage risks related to foreign currencies, interest rates and the net investment risk in our foreign subsidiaries. Our objectives for holding derivatives include reducing, eliminating, and efficiently managing the economic impact of these exposures as effectively as possible. Our derivative programs include strategies that both qualify and do not qualify for hedge accounting treatment.

Hedges of Foreign Currency Risk - We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure. At March 31, 2021 and December 31, 2020, we had $268.2 million and $276.2 million, respectively, of outstanding foreign currency forward agreements that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC No. 815.  We have recorded foreign currency forward agreements with a fair value of $0.2  on million our consolidated balance sheet.   

Hedges of Interest Rate and Net Investment Risk -The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  

The table below sets forth the fair value of the Company’s interest rate related derivative financial instruments as well as their classification on our condensed consolidated balance sheets as of March 31, 2021 and December 31, 2020:

NOTE 12 – Employee Benefit Plans  

We maintain a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees and members of the Board of Directors. The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. We offset our obligations under the Deferred Compensation Plan primarily by investing in the actual underlying investments. At March 31, 2021 and December 31, 2020, these investments totaled approximately $13.2 million and $12.8 million, respectively.

NOTE 13 – Related Parties

We historically conducted business with a related party company, Lite-On Semiconductor Corporation (“LSC”), and its subsidiaries and affiliates.  LSC was also our largest stockholder, owning approximately 15% of our outstanding Common Stock., prior to the close of the acquisition by Diodes.   On November 30, 2020, we acquired LSC and LSC is no longer a stockholder or related party, but instead it is a wholly owned subsidiary of ours. Raymond Soong, the former Chairman of the Board of Diodes, was the Chairman of LSC and was the Chairman of Lite-On Technology Corporation (“LTC”), which was a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and currently the Vice Chairman of the Board of Diodes, was also the Vice Chairman of LSC and a board member of LTC. Dr. Keh-Shew Lu, our current Chairman of the Board, President and Chief Executive Officer, is a board member of LTC and a board member of Nuvoton Technology Corporation (“Nuvoton”). We purchase wafers from Nuvoton for use in our production process. We also conduct business with Nuvoton and its subsidiaries and affiliates. We consider our relationship with Nuvoton to be mutually beneficial and we plan to continue our strategic alliance with Nuvoton.    

We conduct business with Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (“Keylink”). Keylink is our 5% joint venture partner in our Shanghai assembly and test facilities.   We sell products to, and purchase inventory from, companies owned by Keylink. We sold products to companies owned by Keylink, totaling approximately 1% of our net sales for the three months ended periods ended March 31, 2021 and March 30, 2020.     In addition, our subsidiaries in China lease their manufacturing facilities in Shanghai from, and subcontract a portion of our manufacturing process (metal plating and environmental services) to, Keylink. We also pay a consulting fee to Keylink. The aggregate amounts paid to Keylink for the three months ended March 31, 2021 and, 2020 were approximately $4.3 million and $3.1 million, respectively.   In addition, Chengdu Ya Guang Electronic Company Limited (“Ya Guang”) is our 2% joint venture partner in one of our Chengdu assembly and test facilities and our 5% partner in our other Chengdu assembly and test facilities; however, we have no material transactions with Ya Guang, other than these joint ventures.  We also purchase materials from Jiyuan Crystal Photoelectric Frequency Technology Ltd. (“JCP”) a frequency control product manufacturing company in which we have made an equity investment and account for using the equity method of accounting.

Note 14 –Acquisitions and Divestitures

Manufacturing Subsidiary Located in China

In March 2021 Diodes entered into an agreement to sell a manufacturing subsidiary in China for total consideration of approximately $18.0 million, which includes a combination of cash and equity. The transaction is expected to close within the next twelve months and is subject to customary closing conditions and working capital adjustments.

Management determined that the disposal group met the held-for-sale criteria and reclassified the carrying value of the disposal group to assets held-for-sale, which is included in prepaid expenses and other in the consolidated balance sheet. The Company recognized no gain or loss on the reclassification of the disposal group to held-for-sale.

LSC Acquisition

On November 30, 2020, the Company closed on its previously announced acquisition of LSC, a Taiwan-based supplier of “green” power-related discrete and analog semiconductor devices. The Company purchased LSC in order to include LSC’s “green” power-related semiconductor devices that are designed for power saving and low power dissipation to serve the power supply market, and to reacquire the 7,765,778 of the Company’s common shares owned by LSC, which was approximately 15% of our outstanding shares prior to the close of such acquisition. The reacquired shares were treated as a settlement of a pre-existing relationship and as a transaction separate and apart from the business combination along with the settlement of payables and receivables between the Company and LSC.  The reacquired shares are included in treasury stock on the Company’s balance sheet. There was no gain or loss on the settlement of the payables and receivables between the Company and LSC.

The Company recorded the purchase of LSC as a business combination, with the Company owning 100% of LSC.  LSC has been consolidated into the operations of the Company. The purchase price per the Share Swap Agreement was 42.50 TWD per outstanding LSC share. On November 30, 2020, the Company acquired the 307,371,139 outstanding shares of LSC for a total aggregate purchase price of approximately $453.4 million and total consideration of $154.0 million after adjustments for the settlement of pre-existing relationships. A portion of the LSC purchase price was funded by borrowings under the Company’s Credit Agreement.

The table below sets forth the fair value of the LSC assets acquired and liabilities assumed based on relative fair value at the date of acquisition and the corresponding line item in the Company’s consolidated balance sheet at the date of acquisition. During the period from January 1, 2021 and March 31, 2021, measurement period adjustments were made to inventories, property, plant and equipment, and accrued liabilities and other.  The adjustments represented a decrease to total assets acquired and a decrease to total liabilities assumed of $0.1 million. U.S. GAAP permits companies to complete the final determination of the fair values during the measurement period following the acquisition date. The size and breadth of the LSC acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date including (i) changes in fair values of property, plant and equipment and inventories, (ii) changes in fair value of certain liabilities assumed and (iii) tax impact associated with any other changes in fair value. Any potential adjustments made could be material in relation to the preliminary values. A final determination of the LSC assets acquired and liabilities assumed has not been completed and the table below is considered preliminary. The Company engaged a third party valuation specialist to assist with

-20-

the assessment of any intangibles assets acquired as part of the LSC acquisition, and it was determined that there were no intangible assets as a result of the LSC acquisition.

Savitech Acquisition

On February 5, 2020, the Company entered into an agreement to invest up to approximately $14.2 million to acquire at least 51% of Savitech Corporation (“Savitech”), a fabless semiconductor design company located in Zhubei City, Taiwan.  The Company will make the investment in two tranches.  The first tranche of $5.6 million, which provided the Company with a 33.6% ownership of Savitech, was made on March 4, 2020.  The initial tranche was funded with cash on hand. The second tranche, currently recorded in accrued liabilities and other, as shown in the table below, and currently valued at $8.5 million will increase the Company’s ownership to at least 51% of Savitech. The second tranche will be paid on June 30, 2021, provided Savitech achieves previously agreed-to revenue levels.  If revenue levels are not achieved the Company will pay less than the maximum $8.6 million, but regardless of the amount paid for the second tranche, the Company will still acquire at least 51% of Savitech.

The Company recorded the purchase of Savitech as a business acquisition and now consolidates Savitech into its operations, based on the voting model, with a non-controlling interest related to the interest the Company does not own in Savitech. The Company made its investment in Savitech in order to increase the Company’s integrated circuit business.   Total purchase consideration recorded was $13.9 million. The goodwill will not be tax deductible. The Company also incurred acquisition costs of approximately $0.1 million that were recognized in selling, general and administrative expense. The table below sets forth the fair value of the assets and liabilities recorded in the acquisition and the corresponding line item in which the item is recorded in our condensed consolidated balance sheet at the date of acquisition.

Overview

We are a leading global manufacturer and supplier of high-quality, application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets. For detailed information, see Note 1 – Summary of Operations and Significant Accounting Policies, included in the condensed consolidated financial statements in Item 1 above.  Our products are sold primarily throughout Asia, North America and Europe. We believe that our focus on application-specific standard products utilizing innovative, highly efficient packaging and cost-effective process technologies, coupled with our collaborative, customer-focused product development, provides us with a meaningful competitive advantage relative to other semiconductor companies.

Recent Developments

LSC Acquisition

On November 30, 2020, the Company closed the acquisition of Lite-On Semiconductor Corporation (“LSC”), a Taiwan-based supplier of “green” power-related discrete analog semiconductor devices. Since the close of the acquisition the Company has focused on the integration of LSC into its operations.  The Company believes that the integration of LSC is progressing well as we have already begun to realize some of the benefits of manufacturing synergies from improved factory loading with both LSC and Diodes’ products. Our global manufacturing footprint is serving as a key advantage at a time when the broader semiconductor industry is challenged by supply and capacity constraints.

COVID-19

We remain focused on the safety and well-being of our stakeholders and on the service to our customers.  We will continuously review and assess the rapidly-changing COVID-19 pandemic and its impacts on our customers, our suppliers and our business so that we can seek to address those impacts.  We previously temporarily closed a manufacturing facility due to COVID-19 and no assurances can be provided that we will not be required to close or reduce our manufacturing production in the future in response to the COVID-19 pandemic or other events beyond our control.

As of March 31, 2021, our cash, cash equivalents, and short-term investments were $339.5 million, and we had access to additional borrowing capacity of $150.0 million under the revolving portion our Credit Agreement, which we believe assures us adequate liquidity to manage the impacts of the COVID-19 pandemic on our business and to cover cash needs for working capital, capital expenditures and acquisitions for at least the next 12 months. 

See “Risk Factors - The ultimate impact of the COVID-19 pandemic outbreak cannot be estimated at this time, but it may have a material adverse effect on our business, financial condition and results of operations.” in Item 1A of this Quarterly Report on Form 10-Q for an additional discussion of risks and potential risks of the COVID-19 pandemic on our business, financial condition and results of operations.

Net sales increased approximately $132.4 million for the three months ended March 31, 2021, compared to the same period last year, setting a record both organically and on a consolidated basis. This increase in net sales was driven by growth in Asia and Europe. The Company also achieved growth in our computing end market, driven by increases in serial-connectivity products, and the automotive market due to strong organic growth in the automotive business.

The table below sets forth our revenue as a percentage of total revenue by end-user market for the three months ended March 31, 2021 and 2020:

	Three Months Ended
	March 31,
	2021	2020
Industrial	22%	26%
Communications	17%	23%
Consumer	19%	23%
Computing	30%	17%
Automotive	12%	11%

Cost of goods sold increased approximately $89.6 million for the three months ended March 31, 2021, compared to the same period last year, due to the increased net sales during the first quarter of 2021.  As a percent of sales, cost of goods sold was 66.4% for the three months ended March 31, 2021, compared to 65.9% for the same period last year. Average unit cost increased approximately 1.9% for the three months ended March 31, 2021, compared to the same period last year.  For the three months ended March 31, 2021, gross profit increased approximately 44.7% when compared to the same period last year. Gross profit margin for the three month periods ended March 31, 2021 and 2020 was 33.6% and 34.1%, respectively.

Operating expenses for the three months ended March 31, 2021, increased $21.3 million when compared to the three months ended March 31, 2020. Operating expenses as a percentage of net sales was 22.1% and 24.9% for the three months ended March 31, 2021 and 2020, respectively. Selling, general and administrative expenses (“SG&A”) increased approximately $16.5 million, due to higher selling costs and wages and salaries. Research and development expenses (“R&D”) increased approximately $4.0 million due to higher wages and benefits as compared to the same period last year. Amortization of acquisition related intangibles decreased $0.2 million, compared to the same period last year. SG&A, as a percentage of net sales, was 14.2% and 15.0% for the three months ended March 31, 2021 and 2020, respectively. R&D, as a percentage of net sales, was 6.7% and 8.4% for the three months ended March 31, 2021 and 2020, respectively.  

-24-

Interest income increased 181.3% for the three months ended March 31, 2021, compared to the same period last year, due to increased revenue related to cross currency swaps.  Interest expense increased 130.0% for the three months ended March 31, 2021, compared to the same period last year. The increase in interest expense for the three months ended March 31, 2021 was due to the increased debt related to the LSC acquisition and an increase in interest rates on the floating rate portion of our debt. Unrealized gain on investments increased from 2020 due to investment income from an investment the Company acquired in the LSC acquisition.

We recognized an income tax expense of approximately $9.4 million and $4.6 million for the three months ended March 31, 2021 and 2020, respectively. The increase in income taxes for 2021 compared to 2020 was primarily attributable to an increase in pretax book income.  

Financial Condition

Liquidity and Capital Resources

Our primary sources of liquidity are cash and cash equivalents, funds from operations and, if necessary, borrowings under our credit facilities.

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $205.5 million. At March 31, 2021, outstanding borrowings were $67.6 million and outstanding letters of credit were $0.5 million under the Asia credit facilities. In connection with our Asia credit facilities, $54.8 million of cash deposits have been restricted in support of a corresponding loan amount.  During April 2021 $50.0 million of the restricted cash was released from all contractual restrictions, as the applicable loans were repaid in full.

Long-term debt

The Company maintains a long-term credit facility (“Credit Agreement”) consisting of a term loan with a current balance of $218.0 million and a $150.0 million revolving senior credit facility. The Credit Agreement matures in May 2023.

In addition to the liquidity provided by the Credit Agreement, our 51% owned subsidiary, ERIS Technology Corporation (“ERIS”), borrowed $13.3 million through a short term loan and $30.0 million on a long-term basis from local Taiwan banks.  The ERIS debt matures in periods from 2021 through 2033.

At March 31, 2021 and December 31, 2020, our working capital was $617.5 million and $514.2 million, respectively. We expect cash generated by our operations together with existing cash, cash equivalents, short-term investments and available credit facilities to be sufficient to cover cash needs for working capital, capital expenditures and acquisitions for at least the next 12 months.  

Capital expenditures (including accrued capital expenditures) for the three months ended March 31, 2021 and 2020 were $25.1 million and $12.6 million, respectively.  For the first three months of 2021 capital expenditures were approximately 11.5% of our net sales.  While capital expenditures for the three months ended March 31, 2021, is greater than our capital spending target range of 5% to 9% of net sales, we expect our capital expenditure for the twelve months ending December 31, 2021 to be in our target range.  

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of certain European and Asian subsidiaries. As of March 31, 2021, our foreign subsidiaries held approximately $222.6 million of cash, cash equivalents and investments of which approximately $17.8 million would be subject to a potential non-U.S. withholding tax if distributed outside the country in which the cash is currently held. All of this $17.8 million is held in Germany, China, Korea and Taiwan.

As of March 31, 2021, we had short-term investments totaling $8.4 million. These investments are highly liquid with maturity dates greater than three months at the date of purchase. We generally can access these investments in a relatively short time frame but in doing so we generally forfeit all earned and future interest income.

Discussion of Cash Flow

Our primary source of liquidity is cash flow from operations. Additional sources of liquidity are cash and cash equivalents, short-term investments and our credit facilities. Our cash, cash equivalents and restricted cash increased from $326.7 million at December 31, 2020 to $339.5 million at March 31, 2021.  

-25-

The table below sets forth a summary of the condensed consolidated statements of cash flows:

	Three Months Ended March 31,
	2021			2020

Operating Activities

Net cash flows provided by operating activities for the three months ended March 31, 2021 was $68.2 million.  Net cash flows provided by operating activities for the three months ended March 31, 2021 resulted from net income of $40.6 million, depreciation and amortization of intangible assets of $30.5 million, share-based compensation of $6.1 million and an increase in deferred taxes of $1.0 million.  The increases were partially offset by a decrease in noncash working capital accounts of $6.7 million. Net cash flows provided by operating activities for the three months ended March 31, 2020 was $53.7 million.  Net cash flows provided by operating activities for the three months ended March 31, 2020 resulted from net income of $20.4 million, depreciation and amortization of intangible assets of $27.0 million, share-based compensation of $4.7 million and an increase in noncash working capital accounts of $0.8 million. 

Investing Activities

Net cash and cash equivalents used in investing activities was $10.4 million for the three months ended March 31, 2021. Net cash and cash equivalents used in investing activities for the three months ended March 31, 2021 was primarily due to the purchase of property, plant and equipment of $17.2 million, partially offset by net proceeds from the maturity of short-term investments of $2.1 million and other investing cash inflows of $9.1 million for the three months ended March 31, 2021. Net cash and cash equivalents used in investing activities was $17.6 million for the three months ended March 31, 2020. Net cash and cash equivalents used in investing activities was primarily due to the purchase of property, plant and equipment of $14.2 million and the additional investment by the Company’s subsidiary ERIS in Yea-Shin Technology Co., Ltd. (“Yea-Shin”) of $6.1 million, bringing ERIS’ ownership of Yea-Shin to approximately 99.5%. These outflows of cash were partially offset by net proceeds from the maturity of short-term investments of $1.9 million for the three months ended March 31, 2020. 

Financing Activities

Net cash and cash equivalents used in financing activities was $45.4 million for the three months ended March 31, 2021. Net cash used in financing activities in the three months ended March 31, 2021 consisted primarily of $37.2 million of net reductions in our debt and taxes paid on net share settlements of $9.3 million.  Net cash and cash equivalents used in financing activities was $21.4 million for the three months ended March 31, 2020. Net cash used in financing activities in the three months ended March 31, 2020 consisted primarily of $16.6 million of net repayments of long-term debt and taxes paid on net share settlement of $4.5 million.

Use of Derivative Instruments and Hedging

We use interest rate swaps, foreign exchange forward contracts and cross currency swaps to provide a level of protection against interest rate risks and foreign exchange exposure.

Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  

-26-

Hedges of Foreign Currency Risk

We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure and to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC No. 815.  The fair value of our foreign exchange hedges approximates zero.

Off-Balance Sheet Arrangements

We do not have any transactions, arrangements or other relationships with unconsolidated entities that will affect our liquidity or capital resources. We have no special purpose entities that provide off-balance sheet financing, liquidity or market or credit risk support, nor do we engage in leasing, swap agreements, or outsourcing of research and development services that could expose us to liability that is not reflected on the face of our financial statements.

Contractual Obligations

There have been no material changes in our Contractual Obligations as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 22, 2021.  

Critical Accounting Policies

Our critical accounting policies are described in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and in the notes to our consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 22, 2021. Any new accounting policies or updates to existing accounting policies as a result of new accounting pronouncements have been discussed in the notes to our condensed consolidated financial statements in this Quarterly Report on Form 10-Q in Note 1 – Summary of Operations and Significant Accounting Policies. The application of our critical accounting policies may require management to make judgments and estimates about the amounts reflected in the condensed consolidated financial statements. Management uses historical experience and all available information to make these estimates and judgments, and different amounts could be reported using different assumptions and estimates.

Risk Factors

RISKS RELATED TO OUR BUSINESS

The ultimate impact of the COVID-19 pandemic outbreak cannot be estimated at this time, but it may have a material adverse effect on our business, financial condition and results of operations.

During times of difficult market conditions, our fixed costs combined with lower net sales and lower profit margins may have a negative impact on our business, operating results and financial condition.

Downturns in the highly cyclical semiconductor industry or changes in end-market demand could adversely affect our operating results and financial condition.

The semiconductor business is highly competitive, and increased competition may harm our business, operating results and financial condition.

Delays in initiation of production at facilities due to implementing new production techniques or resolving problems associated with technical equipment malfunctions could adversely affect our manufacturing efficiencies, operating results and financial condition.

We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth and profit margins.

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product sales and may demand to audit our operations from time to time.  A failure to qualify a product or a negative audit finding could adversely affect our net sales, operating results and financial condition.

Production at our manufacturing facilities could be disrupted for a variety of reasons, including natural disasters and other extraordinary events, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands and could adversely affect our operating results and financial condition.

New technologies could result in the development of new products by our competitors and a decrease in demand for our products, and we may not be able to develop new products to satisfy changes in demand, which would adversely affect our net sales, market share, operating results and financial condition.

We may be subject to claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result in significant expense, reduction in our intellectual property rights and a negative impact on our business, operating results and financial condition.

We depend on third-party suppliers for timely deliveries of raw materials, manufacturing services, product and process development, parts and equipment, as well as finished products from other manufacturers, and our reputation with customers, operating results and financial condition could be adversely affected if we are unable to obtain adequate supplies in a timely manner.

If we do not succeed in continuing to vertically integrate our business, we will not realize the cost and other efficiencies we anticipate, which could adversely affect our ability to compete, our operating results and financial condition.

Part of our growth strategy involves identifying and acquiring companies. We may be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we may be unable to successfully integrate any acquired companies with our operations, which could adversely affect our business, operating results and financial condition.

We are subject to litigation risks, including securities class action litigation and intellectual property litigation, which may be costly to defend and the outcome of which is uncertain and could adversely affect our business and financial condition.

We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our business, operating results and financial condition.

We may incur additional costs and face emerging risks associated environmental, social and governance (“ESG”) factors impacting our operations.  

-28-

Our products, or products we purchase from third parties for resale, may be found to be defective and, as a result, warranty claims and product liability claims may be asserted against us and we may not have recourse against our suppliers, which may harm our business, reputation with our customers, operating results and financial condition.

We may fail to attract or retain the qualified technical, sales, marketing, finance and management/executive personnel required to operate our business successfully, which could adversely affect our business, operating results and financial condition.

We may not be able to achieve future growth, and any such growth may place a strain on our management and on our systems and resources, which could adversely affect our business, operating results and financial condition.

Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely affect our business, operating results and financial condition.

If our direct sales customers or our distributors’ customers do not design our products into their applications, our net sales may be adversely affected.

We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses, which could adversely affect our business, operating results and financial condition.

Our hedging strategies may not be successful in mitigating our risks associated with interest rates or foreign exchange exposure or our counterparties might not perform as agreed.

We may have a significant amount of debt with various financial institutions worldwide. Any indebtedness could adversely affect our business, operating results, financial condition and our ability to meet payment obligations under such debt.

Restrictions in our credit facilities may limit our business and financial activities, including our ability to obtain additional capital in the future.

Our business benefits from certain Chinese government incentives. Expiration of, or changes to, these incentives could adversely affect our operating results and financial condition.

We operate a global business through numerous foreign subsidiaries, and there is a risk that tax authorities will challenge our transfer pricing methodologies or legal entity structures, which could adversely affect our operating results and financial condition.

The value of our benefit plan assets and liabilities is based on estimates and assumptions, which may prove inaccurate and the actual amount of expenses recorded in the consolidated financial statements could differ materially from the assumptions used.

Changes in actuarial assumptions for our defined benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan and have a negative impact on our cash flows, operating results and financial condition.

Certain of our customers and suppliers require us to comply with their codes of conduct, which may include certain restrictions that may substantially increase our cost of doing business as well as have an adverse effect on our operating efficiencies, operating results and financial condition.

Compliance with government regulations and customer demands regarding the use of “conflict minerals” may result in increased costs and may have a negative impact on our business, operating results and financial condition.

There are risks associated with previous and future acquisitions. We may ultimately not be successful in overcoming these risks or any other problems encountered in connection with acquisitions.

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal control over financial reporting, we may not be able to report our financial results accurately or detect fraud, which could harm our business and the trading price of our Common Stock.

RISKS RELATED TO OUR INTERNATIONAL OPERATIONS

Our international operations subject us to risks that could adversely affect our operations.

We have significant operations and assets in China, the U.K., Germany, Hong Kong and Taiwan and, as a result, will be subject to risks inherent in doing business in those jurisdictions, which may adversely affect our financial performance and operating results.

Significant uncertainties related to changes in governmental policies and participation in international trading partnerships or economic unions currently exist, and, depending upon how such uncertainties are resolved, the changes could have a material adverse effect on us.

Tariffs or other restrictions imposed by the United States Trade Representative may affect our operations in the U.S., may disrupt our activities in the U.S., may have an adverse impact on our profitability and results of operations and may encourage the independent development in China of products and electronic components that will compete with ours or displace our products and components, resulting in an adverse impact on our Chinese business.

-29-

The U.K.’s exit from the European Union will continue to have uncertain effects and could adversely impact our business, results of operations and financial condition.

A slowdown in the Chinese economy could limit the growth in demand for electronic devices containing our products, which would have a material adverse effect on our business, operating results and prospects.

Economic regulation in China could materially and adversely affect our business, operating results and prospects.

We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the U.K.’s Bribery Act 2010, China’s anti-corruption campaign and similar worldwide anti-bribery laws.

We are subject to foreign currency risk as a result of our international operations.

China is experiencing rapid social, political and economic change, which has increased labor costs and other related costs that could make doing business in China less advantageous than in prior years. Increased labor costs in China could adversely affect our business, operating results and financial condition.

We may not continue to receive preferential tax treatment in Asia, thereby increasing our income tax expense and reducing our net income.

The distribution of any earnings of certain foreign subsidiaries may be subject to foreign income taxes, thus reducing our net income.

We could be adversely affected by the compromise or theft of our technology, know-how, data or intellectual property or a requirement that we yield rights in technology, know-how, data stored in foreign jurisdictions or intellectual property that we use in such foreign jurisdictions.

RISKS RELATED TO OUR COMMON STOCK

Variations in our quarterly operating results may cause our stock price to be volatile.

We may enter into future acquisitions and take certain actions in connection with such acquisitions that could adversely affect the price of our Common Stock.

Our directors, executive officers and significant stockholders hold a substantial portion of our Common Stock, which may lead to conflicts with other stockholders over corporate transactions and other corporate matters.

We were formed in 1959, and our early corporate records are incomplete. As a result, we may have difficulty in assessing and defending against claims relating to rights to our Common Stock purporting to arise during periods for which our records are incomplete.

Non-cash tender offers, debt equity swaps or equity exchanges to consummate our business activities are likely to have the effect of diluting the ownership interest of existing stockholders, including qualified stockholders who receive shares of our Common Stock in such business activities.

Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws, may hinder a take-over attempt.

Section 203 of Delaware General Corporation Law may deter a take-over attempt.

Certificate of Incorporation and Bylaw Provisions may deter a take-over attempt.

GENERAL RISK FACTORS

The success of our business depends on the strength of the global economy and the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our net sales, operating results and financial condition.

Production at our manufacturing facilities could be disrupted for a variety of reasons, including natural disasters and other extraordinary events, which could prevent us from producing enough of our products to maintain our sales and satisfy our customers’ demands and could adversely affect our operating results and financial condition.

We may be adversely affected by any disruption in our information technology systems, which could adversely affect our cash flows, operating results and financial condition.

Terrorist attacks, or threats or occurrences of other terrorist activities, whether in the U.S. or internationally, may affect the markets in which our Common Stock trades, the markets in which we operate and our operating results and financial condition.

System security risks, data protection breaches, cyber-attacks and other related cybersecurity issues could disrupt our internal operations, and any such disruption could reduce our expected net sales, increase our expenses, damage our reputation and adversely affect our stock price.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no material changes to our market risks as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 22, 2021.

Item 4. Controls and Procedures.

Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Brett R. Whitmire, with the participation of our management, carried out an evaluation, as of March 31, 2021, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information required to be included in this Quarterly Report is:

• recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms; and

• accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions on required disclosure.

Disclosure controls and procedures, no matter how well designed and implemented, can provide only reasonable assurance of achieving an entity’s disclosure objectives. The likelihood of achieving such objectives is affected by limitations inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty and that breakdowns in internal control can occur because of human failures such as simple errors, mistakes or intentional circumvention of the established processes.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting, known to our Chief Executive Officer or Chief Financial Officer, that occurred in the three months ended March 31, 2021, 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.

The Company is not a party to any pending litigation that we consider material.

From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.

Item 1A. Risk Factors.

There have been no material changes to our risk factors from those disclosed in the Risk Factors section of our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission on February 22, 2021.

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

None.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

None.

disclosure schedules to such agreements or documents contain information that modifies, qualifies and creates exceptions to the representations, warranties and covenants. Moreover, some of the representations and warranties may not be complete or accurate as of a particular date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders and/or were used for the purpose of allocating risk among the parties rather than establishing certain matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.

Basis of Presentation

The condensed consolidated financial data at December 31, 2020 are derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (“SEC”) on February 22, 2021 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K.  All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2021.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter.

Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current condensed consolidated financial statement presentation. E

Earnings Per Share [Abstract]

Earnings Per Share

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.  During the three months ended March 31, 2021 and 2020, we paid no dividends on our Common Stock.

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:

Diluted	$	0.01		$	0.02

 The increase in the effective tax rate for the three months ended March 31, 2021 when compared to the three months ended March 31, 2020, is primarily attributable to a change in pre-tax earnings during the comparable periods. 

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of certain European and Asian subsidiaries.  Any future distributions of foreign earnings will not be subject to additional U.S. income tax, but may be subject to non-U.S. withholding taxes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2012, or for the 2015 tax year. We are no longer subject to China income tax examinations by tax authorities for tax years before 2010. With respect to state and local jurisdictions and countries outside of the U.S. (other than China), with limited exceptions, the Company is no longer subject to income tax audits for years before 2015. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from currently pending tax audits. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in interest expense. As of March 31, 2021, the gross amount of unrecognized tax benefits was approximately $43.9 million.   

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

Share Based Compensation [Abstract]

Share-Based Compensation

NOTE 6 – Share-Based Compensation

For the three months ended March 31, 2021, we recognized stock option expense of approximately $0.02 million.  This stock option expense is related to stock options granted by Savitech Corporation (“Savitech”) in Savitech stock to their employees.  We acquired a controlling interest in Savitech in 2020.  The remainder of our share-based compensation expense was related to share grants. Approximately $0.8 million of cash proceeds were received from stock option exercises during the three months ended March 31, 2021. The table below sets forth the line items where share-based compensation expense was recorded:

	Three Months Ended

Selling, general and administrative		5,033		3,711
Research and development		814		709
Total share-based compensation expense	$	6,122	$	4,693

Share Grants – Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period. All new grants are granted under the Company’s 2013 Equity Incentive Plan, and there will be no additional share grants under the 2001 Omnibus Equity Incentive Plan. Restricted stock grants are measured based on the fair market value of the underlying stock on the date of grant, and compensation expense is recognized on a straight-line basis over the requisite four-year service period. 

Performance stock units (“PSUs”) are measured based on the fair market value of the underlying stock on the date of grant, and compensation expense is recognized over the three-year performance period, with adjustments made to the expense to recognize the probable payout percentage. PSUs will vest upon the Company achieving a cumulative 3-year non-GAAP operating income target for the applicable periods.

As of March 31, 2021, total unrecognized share-based compensation expense related to share grants was approximately $52.2 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.2 years.

Segment Information and Net Sales

NOTE 7 – Segment Information and Net Sales

Segment Reporting. For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various manufacturing and distribution facilities. We aggregate our products because the products are similar and have similar economic characteristics, use similar production processes and share similar customer type. Our primary operations include operations in Asia, North America and Europe. No customer accounted for 10% or more of our net sales or outstanding accounts receivable at any point in the periods presented in this Quarterly Report. 

The tables below set forth net sales based on the location of the subsidiary producing the net sale.

Disaggregation of Net Sales. We disaggregate net sales with customers into direct sales and distribution sales (“Distributors”) and by geographic area. Direct sales customers consist of those customers using our product in their manufacturing process, and Distributors are those customers who resell our products to third parties. We deliver our products to customers around the world for use in consumer electronics, computing, communications, industrial and automotive markets. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months.

The tables below set forth net sales for the Company disaggregated into geographic locations based on shipment and by type (direct sales or Distributor) for the three months ended March 31, 2021 and 2020:

Debt

NOTE 8 – Debt

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $205.5 million. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured, uncommitted and contain no restrictive covenants.  These credit facilities bear interest at LIBOR or similar indices plus a specified margin.  Interest payments are due monthly on outstanding amounts under the credit lines. The unused and available credit under the various facilities as of March 31, 2021, was approximately $127.9  million, net of a $67.6  million advanced under our foreign credit lines and $0.5 million credit used for import and export guarantee. In connection with our Asia credit facilities $54.8 million of cash

deposits have been restricted in support of a corresponding loan amount. During April 2021 $50.0 million of the restricted cash was released from all contractual restrictions, as the applicable loans were repaid in full.

Long-term debt

The Company maintains a long-term credit facility (“Credit Agreement”) consisting of a term loan with a current balance of $218.0 million and a $150.0 million revolving senior credit facility.  The Company used a portion of the proceeds available under the term commitment and the revolving senior credit facility to finance the Company’s acquisition of Lite-On Semiconductor Corporation. The Credit Agreement contains certain financial and non-financial covenants, including, but not limited to, a maximum Consolidated Leverage Ratio, a minimum Consolidated Fixed Charge Coverage Ratio, and restrictions on liens, indebtedness, investments, fundamental changes, dispositions, and restricted payments (including dividends and share repurchases).  Furthermore, under the Credit Agreement, restricted payments, including dividends and share repurchases, are permitted in certain circumstances, including while the pro forma Consolidated Leverage Ratio is, both before and after giving effect to any such restricted payment, at least 0.25 to 1.00 less than the maximum permitted under the Credit Agreement.  In addition to the credit facilities described above, our 51% owned subsidiary, ERIS Technology Corporation (“ERIS”), has short-term debt of $13.3 million and long-term debt of $30.0 million from local Taiwan banks.  The ERIS debt matures in various periods from 2021 through 2033.

Commitments and Contingencies

NOTE 9 – Commitments and Contingencies

Purchase commitments – As of March 31, 2021, we had approximately $58.6 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia.  As of March 31, 2021, we also had a commitment to purchase approximately $40.4 million of wafers to be used in our manufacturing process during 2021 and 2022.  

Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of March 31, 2021, the underfunded liability for this defined benefit plan was approximately $25.1 million.  An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $37.4 million based on a GBP: USD exchange rate of 1.4:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.8 million based on a GBP: USD exchange rate of 1.4:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to

eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million (approximately $0.3 million based on GBP: USD exchange rate oat 1.4:1) in annual installments to cover expenses.

Contingencies – From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods.  Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred.  The Company is not currently a party to any pending litigation that the Company considers material.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 10 – Derivative Financial Instruments

We use derivative instruments to manage risks related to foreign currencies, interest rates and the net investment risk in our foreign subsidiaries. Our objectives for holding derivatives include reducing, eliminating, and efficiently managing the economic impact of these exposures as effectively as possible. Our derivative programs include strategies that both qualify and do not qualify for hedge accounting treatment.

Hedges of Foreign Currency Risk - We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure. At March 31, 2021 and December 31, 2020, we had $268.2 million and $276.2 million, respectively, of outstanding foreign currency forward agreements that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC No. 815.  We have recorded foreign currency forward agreements with a fair value of $0.2  on million our consolidated balance sheet.   

Hedges of Interest Rate and Net Investment Risk -The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  

The table below sets forth the fair value of the Company’s interest rate related derivative financial instruments as well as their classification on our condensed consolidated balance sheets as of March 31, 2021 and December 31, 2020:

NOTE 13 – Related Parties

We historically conducted business with a related party company, Lite-On Semiconductor Corporation (“LSC”), and its subsidiaries and affiliates.  LSC was also our largest stockholder, owning approximately 15% of our outstanding Common Stock., prior to the close of the acquisition by Diodes.   On November 30, 2020, we acquired LSC and LSC is no longer a stockholder or related party, but instead it is a wholly owned subsidiary of ours. Raymond Soong, the former Chairman of the Board of Diodes, was the Chairman of LSC and was the Chairman of Lite-On Technology Corporation (“LTC”), which was a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and currently the Vice Chairman of the Board of Diodes, was also the Vice Chairman of LSC and a board member of LTC. Dr. Keh-Shew Lu, our current Chairman of the Board, President and Chief Executive Officer, is a board member of LTC and a board member of Nuvoton Technology Corporation (“Nuvoton”). We purchase wafers from Nuvoton for use in our production process. We also conduct business with Nuvoton and its subsidiaries and affiliates. We consider our relationship with Nuvoton to be mutually beneficial and we plan to continue our strategic alliance with Nuvoton.    

We conduct business with Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (“Keylink”). Keylink is our 5% joint venture partner in our Shanghai assembly and test facilities.   We sell products to, and purchase inventory from, companies owned by Keylink. We sold products to companies owned by Keylink, totaling approximately 1% of our net sales for the three months ended periods ended March 31, 2021 and March 30, 2020.     In addition, our subsidiaries in China lease their manufacturing facilities in Shanghai from, and subcontract a portion of our manufacturing process (metal plating and environmental services) to, Keylink. We also pay a consulting fee to Keylink. The aggregate amounts paid to Keylink for the three months ended March 31, 2021 and, 2020 were approximately $4.3 million and $3.1 million, respectively.   In addition, Chengdu Ya Guang Electronic Company Limited (“Ya Guang”) is our 2% joint venture partner in one of our Chengdu assembly and test facilities and our 5% partner in our other Chengdu assembly and test facilities; however, we have no material transactions with Ya Guang, other than these joint ventures.  We also purchase materials from Jiyuan Crystal Photoelectric Frequency Technology Ltd. (“JCP”) a frequency control product manufacturing company in which we have made an equity investment and account for using the equity method of accounting.

The Audit Committee of the Board reviews all related party transactions for potential conflict of interest situations on an ongoing basis, all in accordance with such procedures as the Audit Committee may adopt from time to time.

Manufacturing Subsidiary Located in China

In March 2021 Diodes entered into an agreement to sell a manufacturing subsidiary in China for total consideration of approximately $18.0 million, which includes a combination of cash and equity. The transaction is expected to close within the next twelve months and is subject to customary closing conditions and working capital adjustments.

Management determined that the disposal group met the held-for-sale criteria and reclassified the carrying value of the disposal group to assets held-for-sale, which is included in prepaid expenses and other in the consolidated balance sheet. The Company recognized no gain or loss on the reclassification of the disposal group to held-for-sale. A final determination of the value of the assets and liabilities divested has not been completed and the table below is considered preliminary. The table below sets forth the major classes of assets and liabilities that have been classified as held-for-sale on the condensed consolidated balance sheet:

LSC Acquisition

On November 30, 2020, the Company closed on its previously announced acquisition of LSC, a Taiwan-based supplier of “green” power-related discrete and analog semiconductor devices. The Company purchased LSC in order to include LSC’s “green” power-related semiconductor devices that are designed for power saving and low power dissipation to serve the power supply market, and to reacquire the 7,765,778 of the Company’s common shares owned by LSC, which was approximately 15% of our outstanding shares prior to the close of such acquisition. The reacquired shares were treated as a settlement of a pre-existing relationship and as a transaction separate and apart from the business combination along with the settlement of payables and receivables between the Company and LSC.  The reacquired shares are included in treasury stock on the Company’s balance sheet. There was no gain or loss on the settlement of the payables and receivables between the Company and LSC.

The Company recorded the purchase of LSC as a business combination, with the Company owning 100% of LSC.  LSC has been consolidated into the operations of the Company. The purchase price per the Share Swap Agreement was 42.50 TWD per outstanding LSC share. On November 30, 2020, the Company acquired the 307,371,139 outstanding shares of LSC for a total aggregate purchase price of approximately $453.4 million and total consideration of $154.0 million after adjustments for the settlement of pre-existing relationships. A portion of the LSC purchase price was funded by borrowings under the Company’s Credit Agreement.

The table below sets forth the fair value of the LSC assets acquired and liabilities assumed based on relative fair value at the date of acquisition and the corresponding line item in the Company’s consolidated balance sheet at the date of acquisition. During the period from January 1, 2021 and March 31, 2021, measurement period adjustments were made to inventories, property, plant and equipment, and accrued liabilities and other.  The adjustments represented a decrease to total assets acquired and a decrease to total liabilities assumed of $0.1 million. U.S. GAAP permits companies to complete the final determination of the fair values during the measurement period following the acquisition date. The size and breadth of the LSC acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date including (i) changes in fair values of property, plant and equipment and inventories, (ii) changes in fair value of certain liabilities assumed and (iii) tax impact associated with any other changes in fair value. Any potential adjustments made could be material in relation to the preliminary values. A final determination of the LSC assets acquired and liabilities assumed has not been completed and the table below is considered preliminary. The Company engaged a third party valuation specialist to assist with

the assessment of any intangibles assets acquired as part of the LSC acquisition, and it was determined that there were no intangible assets as a result of the LSC acquisition.

Savitech Acquisition

On February 5, 2020, the Company entered into an agreement to invest up to approximately $14.2 million to acquire at least 51% of Savitech Corporation (“Savitech”), a fabless semiconductor design company located in Zhubei City, Taiwan.  The Company will make the investment in two tranches.  The first tranche of $5.6 million, which provided the Company with a 33.6% ownership of Savitech, was made on March 4, 2020.  The initial tranche was funded with cash on hand. The second tranche, currently recorded in accrued liabilities and other, as shown in the table below, and currently valued at $8.5 million will increase the Company’s ownership to at least 51% of Savitech. The second tranche will be paid on June 30, 2021, provided Savitech achieves previously agreed-to revenue levels.  If revenue levels are not achieved the Company will pay less than the maximum $8.6 million, but regardless of the amount paid for the second tranche, the Company will still acquire at least 51% of Savitech.

The Company recorded the purchase of Savitech as a business acquisition and now consolidates Savitech into its operations, based on the voting model, with a non-controlling interest related to the interest the Company does not own in Savitech. The Company made its investment in Savitech in order to increase the Company’s integrated circuit business.   Total purchase consideration recorded was $13.9 million. The goodwill will not be tax deductible. The Company also incurred acquisition costs of approximately $0.1 million that were recognized in selling, general and administrative expense. The table below sets forth the fair value of the assets and liabilities recorded in the acquisition and the corresponding line item in which the item is recorded in our condensed consolidated balance sheet at the date of acquisition.

Summary of Fair Value of Assets and Liabilities Related to Acquisition Recorded in Condensed Consolidated Balance Sheet

The table below sets forth the fair value of the LSC assets acquired and liabilities assumed based on relative fair value at the date of acquisition and the corresponding line item in the Company’s consolidated balance sheet at the date of acquisition. During the period from January 1, 2021 and March 31, 2021, measurement period adjustments were made to inventories, property, plant and equipment, and accrued liabilities and other.  The adjustments represented a decrease to total assets acquired and a decrease to total liabilities assumed of $0.1 million. U.S. GAAP permits companies to complete the final determination of the fair values during the measurement period following the acquisition date. The size and breadth of the LSC acquisition will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the asset and liability fair values as of the acquisition date including (i) changes in fair values of property, plant and equipment and inventories, (ii) changes in fair value of certain liabilities assumed and (iii) tax impact associated with any other changes in fair value. Any potential adjustments made could be material in relation to the preliminary values. A final determination of the LSC assets acquired and liabilities assumed has not been completed and the table below is considered preliminary. The Company engaged a third party valuation specialist to assist with

the assessment of any intangibles assets acquired as part of the LSC acquisition, and it was determined that there were no intangible assets as a result of the LSC acquisition.

Defined benefit plan, estimated future employer contributions in current fiscal year, description	We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of March 31, 2021, the underfunded liability for this defined benefit plan was approximately $25.1 million.  An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $37.4 million based on a GBP: USD exchange rate of 1.4:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.8 million based on a GBP: USD exchange rate of 1.4:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million (approximately $0.3 million based on GBP: USD exchange rate oat 1.4:1) in annual installments to cover expenses.

Objectives for using derivative instruments	The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.
