Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 18 – Derivative Financial Instruments

In accordance with ASC 815 we recognize derivative instruments on our balance sheet, and we measure them at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate the derivative as being in a hedging relationship, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivative instruments that are designated, and qualify as hedges of the exposure to changes in the fair value are considered fair value hedges. Derivative instruments that are designated, and qualify as hedges of the exposure to variability in expected future cash flows are considered cash flow hedges. Derivative instruments may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. We currently only utilize cash flow hedges and do not use derivatives for trading or speculative purposes.

Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge, or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain risks, even though we elect not to apply hedge accounting under ASC 815. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in the consolidated statements of income. Specific information about the valuations of derivatives is described in Note 1 and classification of derivatives in the fair value hierarchy is described in Note 3. Currently our interest rate swaps and interest rate collars are designated as hedges while our foreign exchange contracts are not designated as hedges.

The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period in which the hedged forecasted transaction affects earnings.

Certain of the Company's agreements with its derivative counterparties contain provisions where if certain merger activity, a change of control, or a capital structure change occurs that materially changes the Company's creditworthiness in an adverse manner, the Company’s counterparty may have the right to terminate any derivative transactions under such agreement.

The company has agreements with each of its derivative counterparties that contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness.

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 December 31, 2021 and 2020, we had outstanding foreign currency forward contracts 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 815. We have recorded foreign currency forward agreements with a fair value of less than $0.4 million as a net asset on our consolidated balance sheet.

The tables below set forth outstanding foreign currency forward contracts at December 31, 2021 and 2020:

Hedges of Interest Rate 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 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.

The table below sets forth information related to the number of and the notional amount of our interest rate related derivative instruments at December 31 2021 and December 31, 2020:


	Number of Instruments			Notional Amount
	2021		2020	2021		2020
Interest rate swaps and collars		-	6	$	-	$	140,000

The table below sets forth the fair value of the Company’s interest rate related derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of December 31, 2021 and December 31, 2020:

We estimate that none of the net derivative losses included in accumulated other comprehensive income (“AOCI”) as of December 31, 2021, will be reclassified into earnings within the following 12 months. No gains or losses were reclassified from AOCI into earnings as a result of forecasted transactions that failed to occur during fiscal year 2021.

Segment Reporting [Abstract]

Segment Information, Revenue and Enterprise-Wide Disclosures

Note 16 – Segment Information, Revenue and Enterprise-Wide Disclosures

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 the same customer type. Our primary operations include operations in Asia, North America and Europe.

Disaggregation of Revenue. We disaggregate net sales from contracts 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. Further, most of our contracts are fixed-price arrangements, and are short term in nature, ranging from days to several months.

Earnings Per Share [Abstract]

Earnings Per Share

Note 2 – Earnings per Share

Basic earnings per share is calculated by dividing net earnings attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive. Earnings per share are computed using the “treasury stock method.”

Acquisitions and Divestitures

Business Combinations [Abstract]

Acquisitions and Divestitures

Note 19 – Acquisitions and Divestitures

Privately Held Wafer Design Company

During July 2021, the Company acquired an interest in an early stage privately held fabless wafer design company by purchasing $10.0 million of preferred stock and a $5.0 million convertible promissory note. As the investment in preferred stock does not have a readily determinable fair value, it will be measured at cost less impairment, and adjusted to fair value if there are any observable price changes for an identical or similar investment of the same issuer. The carrying value of the investment at December 31, 2021 was $10.0 million with no observable price changes occurring during the period. The promissory note is convertible into additional preferred stock, has an interest rate of 3% and is due in July 2026.

Manufacturing Subsidiary Located in China

In March 2021, the Company entered into an agreement to sell a manufacturing subsidiary in China for total consideration of approximately $41.5 million, which included a combination of cash and equity. The cash consideration consists of $15.2 million of agreed upon cash and a $23.3 million working capital adjustment while the equity is valued at $3.1 million, which increases the Company’s investment in the buyer to approximately 10%. The transaction closed in December 2021. The Company and the purchaser of the manufacturing facility have entered into an ongoing agreement in which the purchaser will continue to provide wafer -foundry services, on a preferential basis to the Company.

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 were previously included in prepaid expenses and other in the consolidated balance sheet. Upon closing of the transaction, Management derecognized the amounts previously classified as held-for-sale and recorded a gain on the sale of $9.5 million. The gain is recorded in other income in the Company's consolidated statement of income. Neither the buyer nor the manufacturing facility will be considered related parties after the transaction. The table below sets forth the major classes of assets and liabilities that were previously classified as held-for-sale on the consolidated balance sheet and the gain recognized in other income on the consolidated statement of income:


Assets
Cash and cash equivalents	$	8,936
Accounts receivable, net		16,347
Inventories, net		5,415

Accrued liabilities and other		4,913
Other long-term liabilities		2,471

Net assets disposed	$	33,279

LSC Acquisition

On November 30, 2020, the Company closed 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 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 Diodes and LSC. There was no gain or loss on the settlement of the payables and receivables between the Company and LSC. The cash attributed to the reacquisition of the Diodes shares is presented within the financing section of the statement of cash flows.


Total consideration paid	$	453.4
Less: Settlement of pre-existing relationships
Reacquisition of Diodes stock owned by LSC (1)		(296.8	)
Net accounts receivable on LSC books owed by Diodes		(2.6	)
Total amount of pre-existing relationship settled		(299.4	)
Remaining consideration	$	154.0

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, after measurement period adjustments, and the corresponding line item in the Company’s consolidated balance sheet at the date of acquisition. During the period from January 1, 2021 through November 30, 2021, measurement period adjustments were made to inventories, property, plant and equipment, income tax payable, and accrued liabilities and other. During the period, the Company derecognized an estimated liability that was initially recognized on the opening balance sheet related to dividend payable accrual of approximately $12.8 million, reduced the previously estimated amount of a social insurance liability and an estimated information technology liability by $1.5 million, and recognized an additional income tax payable related to the reacquired shares in the amount of approximately $10.7 million. The adjustments to inventory and property, plant, and equipment were a result of refinements to the preliminary fair value calculation in the amounts of $0.7 million and $4.8 million respectively. The Company also made adjustments to the preliminary deferred tax calculations as a result of the measurement period adjustments described above. 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 necessitated 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. The Company engaged a third party valuation specialist to assist with the assessment of any intangible 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. 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.

These unaudited pro forma consolidated results of operations were derived, in part, from the historical consolidated financial statements of LSC and other available information and assumptions believed to be reasonable under the circumstances. LSC has been conformed to Diodes’ reporting calendar.

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 made 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 was also funded with cash on hand and paid in the third quarter ended September 30, 2021, in the amount of $8.5 million which increased the Company’s ownership to 53% of Savitech.

The Company recorded the purchase of Savitech as a business acquisition and 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 $14.2 million.

Significant Accounting Policies

Principles of consolidation – The consolidated financial statements include the accounts of Diodes Incorporated, its wholly-owned subsidiaries and its controlled majority-owned subsidiaries. We account for equity investments in companies over which we have the ability to exercise significant influence, but do not hold a controlling interest, under the equity method, and we record our proportionate share of income or losses in Interest and other, net in the consolidated statements of income. All significant intercompany balances and transactions have been eliminated.

Use of estimates – The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“GAAP”) requires that management make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The level of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. Actual results may differ from these estimates in amounts that may be material to the consolidated financial statements and accompanying notes.

Revenue recognition – We apply the provisions of Accounting Standards Codification ("ASC") 606 in our revenue recognition practices. ASC 606 defines a performance obligation as a promise in a contract to transfer a distinct good or service to the customer, and under ASC 606 is the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Generally speaking, our performance obligations represent a promise to transfer various semiconductor products, and have the same pattern of revenue recognition. Our performance obligations are satisfied at either a point in time, or over time as work progresses. The vast majority of our revenue from products and services is accounted for at a point in time. Substantially all of our revenue in direct and Distributor sales is recognized at a point in time. Further, the payment terms on our sales are based on negotiations with our customers.

Our customers can order different types of semiconductors in a single contract (purchase order), and each line on a purchase order represents a separate performance obligation. Depending on the terms of an arrangement, we may also be responsible for shipping and handling activities. We have elected to account for shipping and handling as activities to fulfill our promise to transfer the good(s). As such, shipping and handling activities do not represent a separate performance obligation, and are accrued as a fulfillment cost. Further, although we offer warranties on our products, our warranties are considered to be assurance-type in nature and do not cover anything beyond ensuring that the product is functioning as intended. Based on the guidance in ASC 606, assurance-type warranties do not represent separate performance obligations; therefore, the primary performance obligation in the majority of our contracts is the delivery of a specific good through the purchase order submitted by our customer.

We record allowances/reserves for a number of items. The following items are the largest dollar items for which we record allowances/reserves, with ship and debit making up the vast majority: (i) ship and debit, which arise when we issue credit to certain distributors upon their shipments to their end customers; (ii) stock rotation, which are contractual obligations that permit certain distributors, up to four times a year, to return a portion of their inventory based on historical shipments to them in exchange for an equal and offsetting order; and (iii) price protection, which arise when market conditions cause average selling prices to decrease and we issue credit to certain distributors on their inventory. Ship and debit reserves are recorded as a reduction to net sales with a corresponding reduction to accounts receivable. Stock rotation reserves and price protection reserves are recorded as a reduction to net sales with a corresponding increase in accrued liabilities.

We also assess our customer’s ability and intention to pay, which is based on a variety of factors including our customer’s historical payment experience, their financial condition and the condition of the global economy and financial markets. Payment terms and conditions typically vary depending on negotiations with the customer.

Net sales are reduced in the period of sale for estimates of product returns and other allowances including distributor adjustments, which were approximately $220.3 million, $194.7 million and $163.9 million in 2021, 2020 and 2019, respectively.

Product warranty – We generally warrant our products for a period of one year from the date of sale. Historically, warranty expense has not been material.

Cash, cash equivalents, and short-term investments – We consider all highly liquid investments with maturity of three months or less at the date of purchase to be cash equivalents. We currently maintain substantially all of our day-to-day operating cash balances with major financial institutions. We hold short-term investments consisting of time deposits, which are highly liquid with maturity dates greater than three months at the date of purchase. Generally, we can access these investments in a relatively short amount of time but in doing so we generally forfeit a portion of interest income. See Note 3 below for additional information regarding fair value of financial instruments.

Allowance for doubtful accounts – We evaluate the collectability of our accounts receivable based upon a combination of factors, including the current business environment and historical experience. If we are aware of a customer’s inability to meet its financial obligations, we record an allowance to reduce the receivable to the amount we reasonably believe will be collected from the customer. For all other customers, we record an allowance based upon the amount of time the receivables are past due. If actual accounts receivable collections differ from these estimates, an adjustment to the allowance may be necessary with a resulting effect on operating expense. Accounts receivable are presented net of valuation allowance, which were approximately $4.3 million at December 31, 2021 and $3.8 million at December 31, 2020.

Inventories – Inventories are stated at the lower of cost or net realizable value. Cost is determined principally by the first-in, first-out method. Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. Any write-down of inventory to the lower of cost or net realizable value at the close of a fiscal period creates a new cost basis that subsequently would not be marked up based on changes in underlying facts and circumstances. On an on-going basis, we evaluate inventory for obsolescence and slow-moving items. This evaluation includes analysis of sales levels, sales projections, and purchases by item, as well as raw material usage related to our manufacturing facilities. If our review indicates a reduction in utility below carrying value, we reduce inventory to a new cost basis. If future demand or market conditions are different than our current estimates, an

inventory adjustment to write down inventory may be required, and would be reflected in cost of goods sold in the period the revision is made.

Property, plant and equipment – Purchased property, plant and equipment is recorded at historical cost, and property, plant and equipment acquired in a business combination is recorded at fair value on the date of acquisition. Property, plant and equipment is depreciated using straight-line methods over the estimated useful lives, which range from 20 to 55 years for buildings and 3 to 10 years for machinery and equipment. The estimated lives of leasehold improvements range from 3 to 5 years, and are amortized over the shorter of the remaining lease term or their estimated useful lives.

Goodwill and other indefinite lived intangible assets – Goodwill and indefinite lived assets are tested for impairment on an annual basis or when an event or changes in circumstances indicate that its carrying value may not be recoverable. Goodwill impairment is tested at the reporting unit level, which is defined as an operating segment or one level below the operating segment. Diodes has one operating segment. No goodwill impairment occurred in 2021, 2020, or 2019. Goodwill is reviewed for impairment using either a qualitative assessment or a quantitative goodwill impairment test. If we choose to perform a qualitative assessment and determine the fair value more likely than not exceeds the carrying value, no further evaluation is necessary. When we perform the quantitative goodwill impairment test, we compare fair value to carrying value, which includes goodwill. If fair value exceeds carrying value, the goodwill is not considered impaired. If the carrying value is higher than the fair value, the difference would be recognized as an impairment loss.

Impairment of long-lived assets – Our long-lived assets are reviewed whenever events or changes in circumstances indicate that the carrying value may not be recoverable. We consider assets to be impaired if the carrying value exceeds the undiscounted projected cash flows from operations. If impairment exists, the assets are written down to fair value or to the projected discounted cash flows from related operations. As of December 31, 2021, we expect the remaining carrying value of assets to be recoverable.

Business combinations – We account for acquired businesses using the acquisition method of accounting, which requires that once control of a business is obtained, 100% of the assets acquired and liabilities assumed, including amounts attributed to noncontrolling interests, be recorded at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill.

For significant acquisitions we may use independent third-party valuation specialists to assist us in determining the fair value of assets acquired and liabilities assumed.

Significant judgment is often required in estimating the fair value of assets acquired and liabilities assumed. The Company makes estimates and assumptions about conditions of the assets, other costs not captured in the base costs, and consideration for entrepreneurial profit, depreciation, functional obsolescence, and economic obsolescence allocated to the various property, plant and equipment categories considering the perspective of marketplace participants.

While management believes those expectations and assumptions are reasonable, they are inherently uncertain. Unanticipated market or macroeconomic events and circumstances may occur, which could affect the accuracy or validity of the estimates and assumptions, which could result in subsequent impairments.

During the normal course of business the Company pursues acquisitions. See Note 19 for additional information regarding business acquisitions.

Equity investments – We regularly invest in equity securities of public and private companies to promote business and strategic objectives. Equity investments are measured and recorded as follows:

Marketable equity securities are equity securities with readily determinable fair value ("RDFV") that are measured and recorded at fair value on a recurring basis with changes in fair value, whether realized or unrealized, recorded through the income statement.

Non-marketable equity securities are equity securities without RDFV that are measured and recorded using a measurement alternative that measures the security at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes.

Equity-method investments are equity securities in investees we do not control but over which we have the ability to exercise significant influence. Equity method investments are measured at cost minus impairment, if any, plus or minus our share of equity method investee income or loss. Our proportionate share of the income or loss from equity method investments is typically recognized on a one-quarter lag.

Income taxes – Income taxes are accounted for using an asset and liability approach whereby deferred tax assets and liabilities are recorded for differences in the financial reporting bases and tax bases of our assets and liabilities. If it is more likely than not that some portion of deferred tax assets will not be realized, a valuation allowance is recorded.

GAAP prescribes a comprehensive model for how companies should recognize, measure, present, and disclose in their financial statements uncertain tax positions taken or expected to be taken on a tax return. Tax positions shall initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions shall initially and subsequently be measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and all relevant facts. All deferred income taxes are classified as noncurrent assets or noncurrent liabilities on the consolidated balance sheet as of December 31, 2021 and 2020, respectively.

Research and development costs – Internally-developed research and development costs are expensed as incurred. Acquired in-process research and development (“IPR&D”) is capitalized as an indefinite-lived intangible asset and evaluated periodically for impairment. When the project is completed, an expected life is determined and the IPR&D is amortized as an expense over the expected life.

Shipping and handling costs – Shipping and handling costs for products shipped to customers, which are included in selling, general and administrative expenses, were approximately $24.1 million, $16.6 million and $13.9 million for the twelve months ended December 31, 2021, 2020 and 2019, respectively.

Concentration of credit risk – Financial instruments, which potentially subject us to concentrations of credit risk, include trade accounts receivable. Credit risk is limited by the dispersion of our customers over various geographic areas, operating primarily in electronics manufacturing and distribution. We perform a credit evaluation of new customers and monitor the accounts receivable aging of our existing customers. Generally we require no collateral from our customers and historically credit losses have been insignificant.

We currently maintain substantially all of our day-to-day cash balances and short-term investments with major financial institutions. Cash balances are usually in excess of Federal and/or foreign deposit insurance limits.

Valuation of financial instruments – The carrying value of our financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, credit line, and long-term debt approximate fair value due to their current market conditions, maturity dates and other factors.

Share-based compensation – We use the Black-Scholes-Merton model to determine the fair value of stock options on the date of grant and recognize compensation expense for stock options on a straight-line basis. 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 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.

The amount of compensation expense recognized using the Black-Scholes-Merton model requires us to exercise judgment and make assumptions relating to the factors that determine the fair value of our stock option grants. The fair value calculated by this model is a function of several factors, including the grant price, the expected future volatility, the expected term of the option and the risk-free interest rate of the option. The expected term and expected future volatility of the options require judgment. In addition, we estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest. We estimate the forfeiture rate based on historical experience, and to the extent our actual forfeiture rate is different from our estimate, share-based compensation expense is adjusted accordingly.

Treasury stock – We currently have no program authorized by our board of directors to purchase shares of our common stock. Shares than have been previously acquired recorded as treasury stock, at cost, the measurement date of cost being date of purchase, as a reduction to stockholder’ equity.

During the fourth quarter of 2020, as part of the Lite-On Semiconductor acquisition, the Company reacquired 7,765,778 shares of its Common Stock.

Functional currencies and foreign currency translation – We translate the assets and liabilities of our non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates on the balance sheet date. Net sales and expense for these subsidiaries are translated at the weighted-average exchange rate during the period presented. Resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income or loss within stockholders’ equity in the consolidated balance sheets. Included in other income are foreign exchange losses of approximately $2.1 million for the twelve months ended December 31, 2021, approximately $9.8 million for the twelve months ended December 31, 2020, and approximately $3.7 million for the twelve months ended December 31, 2019.

Defined benefit plan – We maintain plans covering certain of our employees in the U.K. The overfunded or underfunded status of pension and postretirement benefit plans are recognized on the balance sheet. Actuarial gains and losses, and prior service costs or credits, are recognized in other comprehensive income (loss), net of tax effects, until they are amortized as a component of net periodic benefit cost. For financial reporting purposes, the net pension and supplemental retirement benefit obligations and the related periodic pension costs are calculated based upon, among other things, assumptions of the discount rate for plan obligations, estimated return on pension plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses. The expected long-term return on plan assets was determined based on historical and expected future returns of the various asset classes. The plan’s investment policy includes a mandate to diversify assets and invest in a variety of asset classes to achieve its expected long-term return and is currently invested in a variety of funds representing most standard equity and debt security classes. Trustees of the plan may make changes at any time. As part of the LSC acquisition we have assumed the liability associated with a defined benefit plan for certain LSC employees. The net liability assumed was approximately $4.7 million, as of December 31, 2020.

Noncontrolling interest - Noncontrolling interest primarily relates to the minority investors’ share of the earnings of certain China and Taiwan subsidiaries. Noncontrolling interests are a separate component of equity and not a liability. Increases or decreases in noncontrolling interest, due to changes in our ownership interest of the subsidiaries that leave control intact, are recorded as equity transactions. The noncontrolling interest in our subsidiaries and their equity balances are reported separately in the consolidated financial statements, and activities of these subsidiaries are included therein.

Contingencies – From time to time, we may be involved in a variety of legal matters that arise in the normal course of business. Based on information available, we evaluate the likelihood of potential outcomes. We record and disclose the appropriate liability when the amount 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.

Comprehensive income (loss) – GAAP generally requires that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income, are components of comprehensive income or loss. The components of accumulated other comprehensive income or loss include foreign currency translation adjustments and unrealized gain or loss on defined benefit plan. Accumulated other comprehensive loss was approximately $50.5 million, $73.6 million and $108.1 million at December 31, 2021, 2020 and 2019, respectively.

As of December 31, the accumulated balance for each component of comprehensive income is as follows:


	2021			2020
Unrealized foreign currency losses	$	(7,760	)	$	(21,614	)
Unrealized gain on cross currency and interest rate swaps, net of tax	$	(2,157	)	$	(3,574	)
Unrealized loss on defined benefit plan	$	(40,600	)	$	(48,418	)

Reclassifications – Certain immaterial amounts from prior periods have been reclassified to conform to the current years’ presentation.

Recently Issued Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) which could have potential impact to the Company’s financial statements:

In November 2021, the FASB issued ASU No. 2021-10 Government Assistance (Topic 832), Disclosures by Business Entities About Government Assistance, which requires entities to provide disclosures on material government assistance transactions for annual reporting periods. The disclosures include information around the nature of the assistance, the related accounting policies used to account for government assistance, the effect of government assistance on the entity’s financial statements, and any significant terms and conditions of the agreements, including commitments and contingencies. The new standard is effective for the Company on January 1,

2022 and only impacts annual financial statement footnote disclosures. The adoption will not have a material effect on our consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848). ASU No. 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU No. 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the second quarter of 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.6 million based on a GBP: USD exchange rate of 1:1.3 ) 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 in annual installments effective April 1, 2020 to cover expenses.

Defined benefit plans, general information	In connection with the Zetex acquisition, we adopted a contributory defined benefit plan that covers certain employees in the U.K. The defined benefit plan is closed to new entrants and frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of each eligible employee. We determined the fair value of the defined benefit plan assets and utilize an annual measurement date of December 31. At subsequent measurement dates, defined benefit plan assets will be determined based on fair value. Defined benefit plan assets consist of a diverse range of listed and unlisted securities including corporate bonds and mutual funds and are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. The net pension and supplemental retirement benefit obligations and the related periodic costs are based on, among other things, assumptions of the discount rate, estimated return on plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions.
Defined benefit plan, pension, method to determine vested benefit obligation	The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.

Uncertain Tax Positions

In accordance with the provisions related to accounting for uncertainty in income taxes, we recognize the benefit of a tax position if the position is “more likely than not” to prevail upon examination by the relevant tax authority. The table below sets forth a reconciliation of the beginning and ending amount of unrecognized tax benefits:


	2021			2020			2019
Balance at January 1,	$	42,466		$	35,652		$	32,209
Additions based on tax positions related to the current year		9,244			7,495			9,274
Additions for prior year tax positions		138			4,952			39
Reductions for prior year tax positions		(8,470	)		(5,633	)		(5,870	)
Balance at December 31,	$	43,378		$	42,466		$	35,652

If the $43.4 million of unrecognized tax benefits as of December 31, 2021, is recognized, approximately $41.3 million would affect the effective tax rate. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions will significantly increase or decrease within the next 12 months. These changes may be the result of settlements of ongoing audits or competent authority proceedings. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.

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 tax year 2015. We are no longer subject to China income tax examinations by tax authorities for tax years before 2011. With respect to state and local jurisdictions and countries outside of the U.S., with limited exceptions, we are no longer subject to income tax audits for years before 2016. Although the outcome of tax audits is always uncertain, we believe that adequate amounts of tax, interest and penalties, if any, have been provided for in our reserve for any adjustments that may result from future tax audits. We recognize accrued interest and penalties, if any, related to unrecognized tax benefits in interest expense. We had an immaterial amount of accrued interest and penalties at December 31, 2021, 2020 and 2019.

ASU No. 2013-11 provides that an entity is required to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The $11.0 million net deferred tax liabilities presented in the balance sheet as of December 31, 2021, is net of $11.7 million of unrecognized tax benefits. The $0.8 million and $35.3 million net deferred tax asset presented above for December 31, 2021 and 2020, respectively, is prior to the net balance sheet presentation required by ASU 2013-11.

At December 31, 2021, we had no federal research credit carryforward and approximately $10.0 million of state tax credit and research credit carryforwards, which are available to offset future income tax liabilities. The state tax credit carryforwards will begin to expire in 2021. Consistent with prior years, we determined that it is more likely than not that our state research credit carryforwards will expire before they are utilized. The valuation allowances recorded against the related deferred tax assets totaled $9.0 million as of December 31, 2021 and 2020.

At December 31, 2021, we had state net operating loss (“NOL”) carryforwards of approximately $1 million, and foreign NOL carryforwards of $210 million which are available to offset future taxable income. The state NOL carryforward will begin to expire in 2021. We determined that it is more likely than not that the state NOL carryforwards will expire before they are fully utilized and recorded a full valuation allowance on the related deferred tax assets. The foreign NOL carryforwards will begin to expire in 2021. We determined that it is more likely than not that a portion of the foreign NOL carryforwards will expire before they are fully utilized. The valuation allowances recorded against the related deferred tax assets totaled $36 million and $32 million as of December 31, 2021 and 2020, respectively.

Supplemental Information

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of European and Asian subsidiaries. As of December 31, 2021, we had undistributed earnings from non-U.S. operations of approximately $1.5 billion (including approximately $207 million of restricted earnings, which are not available for dividends). Undistributed earnings of our China subsidiaries comprise $449 million of this total. Additional Chinese withholding taxes of approximately $45 million would be required should the $449 million of such earnings be distributed out of China as dividends.

The impact of tax holidays decreased our tax expense by approximately ($0.2) million, $0.9 million and $3.1 million for the years ended December 31, 2021, 2020 and 2019, respectively. The benefit of the tax holidays on basic and diluted earnings per share was $0.00, $0.02 and $0.06 for the twelve months ended December 31, 2021, 2020 and 2019, respectively.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Employee Benefit Plans

Note 13 – Employee Benefit Plans

Defined Benefit Plan

In connection with the Zetex acquisition, we adopted a contributory defined benefit plan that covers certain employees in the U.K. The defined benefit plan is closed to new entrants and frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of each eligible employee. We determined the fair value of the defined benefit plan assets and utilize an annual measurement date of December 31. At subsequent measurement dates, defined benefit plan assets will be determined based on fair value. Defined benefit plan assets consist of a diverse range of listed and unlisted securities including corporate bonds and mutual funds and are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. The net pension and supplemental retirement benefit obligations and the related periodic costs are based on, among other things, assumptions of the discount rate, estimated return on plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses. All unrecognized actuarial gains and losses, prior service costs and accumulated other comprehensive income are eliminated and the balance sheet liability is set equal to the funded status of the defined benefit plan at acquisition date.

The table below sets forth net periodic benefit costs of the plan for the twelve months ended December 31:


	Defined Benefit Plan
	2021			2020
Components of net periodic benefit cost:
Service cost	$	275		$	257
Interest cost		2,269			3,035
Recognized actuarial loss		2,959			2,100
Expected return on plan assets		(7,266	)		(7,405	)
Prior service cost		72			56
Net periodic benefit cost	$	(1,691	)	$	(1,957	)

The table below sets forth the benefit obligation, the fair value of plan assets, and the funded status as of December 31:


	Defined Benefit Plan
	2021			2020
Change in benefit obligation:
Beginning balance	$	175,292		$	158,680
Service cost		275			257
Interest cost		2,269			3,027

Change in plan assets:
Beginning balance - fair value	$	147,861		$	132,621
Employer contribution		3,027			2,822
Actual return on plan assets		10,314			12,535
Benefits paid		(4,451	)		(4,769	)
Currency changes		(1,722	)		4,652
Fair value of plan assets at December 31	$	155,029		$	147,861
Underfunded status at December 31	$	(11,735	)	$	(27,431	)

Based on an actuarial study performed as of December 31, 2021, the plan was underfunded by approximately $11.7 million and the liability is reflected in our consolidated balance sheets as a noncurrent liability and the amount recognized in accumulated other comprehensive loss was approximately $39.4 million.

We apply the “10% corridor” approach to amortize unrecognized actuarial gains (losses). Under this approach, only actuarial gains (losses) that exceed 10% of the greater of the projected benefit obligation or the market-related value of the plan assets are amortized. For the twelve months ended December 31, 2021, the plan’s accumulated other comprehensive loss increased by approximately $11.0 million. The variance between the actual and expected return to plan assets during 2021 decreased the total unrecognized net loss by approximately $3.0 million. The total unrecognized net loss is more than 10% of the projected benefit obligation and 10% of the plan assets. Therefore, the excess amount will be amortized over the average term to retirement of plan participants, not yet in receipt of pension, which as of December 31, 2021, was approximately 8.5 years. The following weighted-average assumptions were used to determine net periodic benefit costs for the twelve months ended December 31:


	2021			2020
Discount rate		1.9	%		1.3	%
Expected long-term return on plan assets		5.3	%		4.9	%

The following weighted-average assumption was used to determine the benefit obligations at December 31:


	2021			2020
Discount rate		1.9	%		1.3	%

The expected long-term return on plan assets was determined based on historical and expected future returns of the various asset classes. The plan’s investment policy includes a mandate to diversify assets and invest in a variety of asset classes to achieve its expected long-term return and is currently invested in a variety of funds representing most standard equity and debt security classes. Trustees of the plan may make changes at any time. The table below sets forth the plan asset allocations of the assets in the plan and expected long-term return by asset category:


Asset category	Expected long-term return			Asset allocation
Growth assets		7.0	%		70	%
Hedging assets		1.2	%		28	%
Cash		0.3	%		2	%


2022	$	4,942
2023		5,354
2024		5,725
2025		5,816
2026		5,946
2027-2031		32,224

The trustees are required to review the funding position every three years. An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $34.7 million based on a GBP: USD exchange rate of 1:1.3). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.6 million based on a GBP: USD exchange rate of 1:1.3 ) 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 in annual installments effective April 1, 2020 to cover expenses.

The defined benefit plan’s investment strategy is to invest 65% in growth strategy assets and 35% in hedging strategy assets. The growth strategy consists of a highly diversified set of assets, and the hedging component is designed to hedge a significant proportion of the plan’s interest and inflation rate risks. The overall strategy is designed to return a long-term return of 2.6% p.a. above the liability benchmark which is broadly equal to changes in the plan’s liabilities.

The plan’s trustees appoint fund managers to carry out all the day-to-day functions relating to the management of the fund and its administration. The fund managers must invest their portion of the plan’s assets in accordance with their investment manager agreement agreed by the trustees. The trustees are responsible for agreeing these investment manager agreements and for deciding on the portion of the plan’s assets that will be invested with each fund manager. When making decisions, the trustees take advice from experts including the plan’s actuary and also have the option to consult with the Company.

The following table summarizes the major categories of the plan assets:


	December 31, 2021
Asset category	Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	9,685	$	-	$	-	$	9,685
Equity securities:
U.K.		-		1,982		-		1,982
Overseas equities		-		46,447		-		46,447
Emerging markets		-		11,662		-		11,662
Fixed income securities:
Government bonds		-		6,289		-		6,289
Non-government bonds		-		7,702		-		7,702
Other types of investments
Hedge funds		-		19,208		-		19,208

Other		-		10		-		10
Total	$	9,685	$	145,344	$	-	$	155,029

Fair value is taken to mean the bid value of securities, as supplied by the fund managers. All the plan’s securities are highly liquid. The plan does not hold any Level 3 securities. See Note 3 for additional information regarding fair value and Levels 1, 2 and 3.

The investment manager agreements require the fund managers to invest in a diverse range of stocks and bonds across each particular asset class. The stocks held by the plan in a particular asset class should therefore match closely the underlying stocks in the relevant index. We believe that this leads to minimal concentration of risk within each asset class; although we recognize that some asset classes are inherently more risky than others.

We also have pension plans in Asia for which the benefit obligation, fair value of the plan assets and the funded status amounts are immaterial and therefore, not included in the amounts or assumptions above. As of December 31, 2021 and 2020, the Company has recorded a net liability of $6.3 million and $6.2 million, respectively, related to these defined benefit plans in Asia.

401(k) Retirement Plan

We maintain a 401(k) retirement plan (the “Plan”) for the benefit of qualified employees at our U.S. locations. Employees who participate may elect to make salary deferral contributions to the Plan up to 100% of the employees’ eligible payroll subject to annual Internal Revenue Code maximum limitations. We currently make a matching contribution of $1 for every $2 contributed by the participant up to 6% (3% maximum matching) of the participant’s eligible payroll, which vests over an initial four years. In addition, we may make a discretionary contribution to the entire qualified employee pool, in accordance with the Plan.

As stipulated by the regulations of China, we maintain a retirement plan pursuant to the local municipal government for the employees in China. We are required to make contributions to the retirement plan at a rate between 10% and 22% of the employee’s eligible payroll. Pursuant to the Taiwan Labor Standard Law and Factory Law, we maintain a retirement plan for the employees in Taiwan, whereby we make contributions at a rate of 6% of the employee’s eligible payroll.

For the years ended December 31, 2021, 2020 and 2019, total amounts expensed under these plans were approximately $21.7 million, $10.2 million and $16.3 million, respectively.

Deferred Compensation Plan

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 December 31, 2021 and December 31, 2020, these investments totaled approximately $15.5 million and $12.8 million, respectively.

Total share-based compensation expense	$	33,205	$	25,260	$	20,535

In May 2013, our stockholders approved our 2013 Equity Incentive Plan (“2013 Plan”). Since the approval of the 2013 Plan, all stock options are granted under the 2013 Plan, and we will not grant any further stock options under our 2001 Plan. Stock options under the 2013 Plan generally vest in equal annual installments over a four-year period and expire eight years after the grant date. The number of shares originally authorized to be awarded under the 2013 Plan was 6 million shares. In May 2017, our stockholders approved an amendment to the 2013 Plan, authorizing and additional 6 million shares to be awarded, bringing the total shares authorized to be awarded under the 2013 Plan to 12 million shares.

Share-based compensation expense for stock options granted in previous years was calculated on the date of grant using the Black-Scholes-Merton option-pricing model. All 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.

Total cash received from option exercises was approximately $4.3 million, $6.8 million and $11.9 million during 2021, 2020 and 2019, respectively.

At December 31, 2021, there was no unrecognized compensation expense related to unvested options.

The table below sets forth a summary of activity in our stock option plan:


Stock Options	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
Outstanding at December 31, 2018		988			23.47			$	8,693

Share Grants – Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period. 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.

The table below sets forth a summary of our non-vested share grants in 2020, 2019 and 2018:


Nonvested at December 31, 2018	1,667		26.68
Granted	670		38.15
Vested	(573	)	24.90
Forfeited	(67	)	30.44

Forfeited and other	(34	)	52.27
Nonvested at December 31, 2021	1,402		54.94	$	153,989

During 2020, in connection with the retirement of a member of the Company’s board of directors, the Company modified that director’s unvested RSU grants to vest upon his retirement. The shares subject to the modified grants will be released to that board member as if they were vesting under the original vesting timeline. In connection with this modification, the Company recorded additional expense of approximately $1.7 million.

The total unrecognized share-based compensation expense as of December 31, 2021, was approximately $59.1 million, relating to share grants, which was expected to be recognized over a weighted average period of approximately 2.2 years.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 3 – Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

We use valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. These two types of inputs create a three-tier fair value hierarchy that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or

liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 Inputs - Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.

As of December 31, 2021, we had short-term and long-term investments. Long-term investments are included with Other long-term assets on the consolidated balance sheet. Trading securities held at December 31, 2021, were purchased on the open market and unrealized gains and losses are included in Other income (expense). The trading securities are valued under the fair value hierarchy using Level 1 Inputs. Short-term investments consist of investments such as time deposits, which are highly liquid with maturity dates greater than three months at the date of purchase. Generally, we can access these short-term investments in a relatively short amount of time but in doing so we generally forfeit a portion of earned and future interest income. Long-term investments consist of certain equity securities acquired as part of the LSC acquisition. Deferred compensation investments consist of the Company’s stock, mutual funds and cash. See Note 13 for additional information related to our deferred compensation program and Note 18 for additional information related to our interest rate swaps and foreign currency hedges. The short-term investments, long-term investments and deferred compensation investments are valued under the fair value hierarchy using Level 1 and Level 2 Inputs.

Financial assets and liabilities carried at fair value as of December 31, 2021, are classified in the following table:


Description	Fair Market Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Changes in Fair Values Included in Current Period Earnings
Short-term investments	$	6,542	$	6,542	$	-	$	-	$	-
Long-term investments		47,001		47,001		-		-		28,018
Cross-currency swap liability		1,330		-		1,330		-		-
Deferred compensation investments		15,483		904		14,579		-		1,527

Financial assets and liabilities carried at fair value as of December 31, 2020 are classified in the following table:


Description	Fair Market Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Changes in Fair Values Included in Current Period Earnings
Short-term investments	$	6,142	$	6,142	$	-	$	-	$	-
Long-term investments		18,295		18,295		-		-		2,083
Cross-currency swap liability		2,305		-		2,305		-		-
Interest-rate swap liability		1,626		-		1,626		-		-
Deferred compensation investments		12,829		691		12,138		-		3,142

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). We believe our long-term debt under our revolving credit facility approximates fair value and is valued under the fair value hierarchy using Level 2 Inputs. Financial assets and financial liabilities measured at fair value on a non-recurring basis were not significant at December 31, 2021 and 2020.

We also are responsible for a pension plan in the U.K. that holds investments carried at fair value. See Note 13 for additional information related to these pension plan investments.

Bank Credit Agreements and Other Short-Term and Long-Term Debt

Note 8 – Bank Credit Agreements and Other Short-term and Long-term Debt

Short-term debt

Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $122.5 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 December 31, 2021, was approximately $103.4 million, net of $18.1 million advanced under our foreign credit lines, attributable to our 51% owned subsidiary, Eris Technology Company ("ERIS"), and $1.0 million credit used for import and export guarantee.

Long-term debt

On December 29, 2021, the Company entered into Amendment No. 6 to Second Amended and Restated Credit Agreement, Consent and Incremental Term Assumption Agreement (the “Amendment”) that amends that certain Second Amended and Restated Credit Agreement dated as of May 29, 2020 (as amended, modified and/or supplemented from time to time prior to the date of the

Amendment, the “Existing Credit Agreement”). Certain capitalized terms used in this description of the Amendment have the meanings given to them in the Amendment or the Existing Credit Agreement.

The Amendment amends and modifies the Company’s existing senior credit facilities under the Existing Credit Agreement as follows: (x) increases the revolving senior credit facility (“Revolver”) amount from $150.0 million to $200.0 million, (y) provides for a new $50.0 million tranche of Incremental Term Loans, which were funded in that amount at the closing of the Amendment (and the proceeds of which were applied to repay $50.0 million of outstanding borrowings under the Revolving Credit Loans), and (z) reduces the interest rate for a new Pricing Level and unused line fees for certain Pricing Levels. The Amendment 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 in excess of $25.0 million and share repurchases). These covenants are generally similar to the corresponding covenants in the Existing Credit Agreement, except that certain amounts permitted as exceptions to the negative covenant restricting investments have been increased, and additional exceptions have been added to the negative covenant on indebtedness allowing unsecured Guarantees by the Company of indebtedness of certain of its Subsidiaries relating to securitization transactions and receivables facilities. 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.

On January 22, 2021, Diodes Hong Kong Limited, a company incorporated under the laws of Hong Kong and a subsidiary of the Company, entered into a Facility Agreement (the “Facility Agreement”) with The Hongkong and Shanghai Banking Corporation Limited and the other parties identified therein pursuant to which Diodes Hong Kong Limited obtained from the lenders a US Dollar revolving loan facility in an aggregate amount equal to $100.0 million. Diodes Hong Kong Limited used a portion of the proceeds from such revolving loan facility (i) to refinance certain existing indebtedness and (ii) to finance working capital requirements and its general corporate purposes.
