ULTRA CLEAN HOLDINGS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization — Ultra Clean Holdings, Inc., (the “Company” or “UCT”) a Delaware corporation, was founded in November 2002 and became a publicly traded company on the NASDAQ Global Market in March 2004. The Company is a global leader in the design, engineering and manufacture of production tools, modules and subsystems for the semiconductor and display capital equipment markets. The Company’s products include chemical delivery modules, frame assemblies, gas delivery systems, fluid delivery systems, precision robotics, process modules as well as other high-level assemblies. The Company’s services provide part cleaning, surface encapsulation, and high sensitivity micro contamination analysis primarily for the semiconductor device makers and wafer fabrication equipment markets.

The Company reports results for two segments: Semiconductor Products and Solutions (“Products” or “SPS”) and Semiconductor Services Business (“Services” or “SSB”).

Basis of Presentation — The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary for the fair financial statement presentation for the dates and periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted. The Company’s December 27, 2019 balance sheet data were derived from its audited financial statements as of that date.

Fiscal Year — The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.

Principles of Consolidation — The Company’s Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries with the ownership interests of minority shareholders presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated upon consolidation.

Noncontrolling interests — The Company recognizes noncontrolling interests to reflect the portion of the equity of the majority-owned subsidiaries which is not attributable, directly or indirectly, to the controlling stockholder. The Company’s consolidated entities include partially-owned entities, which are (1) Cinos Co., Ltd (“Cinos Korea”), a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea, 86.0% of whose equity interests the Company is obligated to purchase and whose results the Company consolidates and (2) Cinos Xian Clean Technology, Ltd. (“Cinos China”), a Chinese entity that is 60.0% owned by Cinos Korea. The interest held by others in Cinos Korea and in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The noncontrolling interests will continue to be attributed their share of gains and losses even if that attribution results in a deficit noncontrolling interests balance.

Segments — The Financial Accounting Standards Board’s (“FASB”) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is the Chief Executive Officer. The Company operates and reports two segments. See Note 15 to the Company’s Consolidated Financial Statements.

Foreign Currency Translation and Remeasurement — The functional currency of the SPS business unit’s foreign subsidiaries is the U.S. dollar. The functional currency of the SSB business unit’s foreign subsidiaries is the local currency except for that of its Singapore and Scotland entities, which is the U.S. dollar.

The functional currency of the Company’s other international subsidiaries is either the U.S. dollar or their local currency. For the Company’s foreign subsidiaries where the local currency is the functional currency, the Company translates the financial statements of these subsidiaries to U.S. dollars using month-end exchange rates for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in AOCI as a component of stockholders' equity. For the Company’s foreign subsidiaries where the U.S. dollar is the functional currency, any gains and losses resulting from the translation of the assets and liabilities of these subsidiaries are recorded in other income (expense), net.

- 9 -

Use of Estimates — The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include inventory valuation, accounting for income taxes, business combinations, valuation of goodwill, intangible assets and long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments routinely require adjustments. Actual amounts may differ from those estimates.

Cash and Cash Equivalents — The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally.

Concentration of Credit Risk — Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company sells its products and provides services primarily to semiconductor capital equipment manufacturers in the United States. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

Two of the Company’s customers accounted for 10% or more of revenues and their related revenues as a percentage of total revenues were as follows:  

	Three Months Ended						Nine Months Ended
	September 25,			September 27,			September 25,			September 27,
	2020			2019			2020			2019
Lam Research Corporation		42.9	%		37.6	%		42.3	%		39.4	%
Applied Materials, Inc.		25.2	%		24.3	%		25.0	%		21.5	%
Total		68.1	%		61.9	%		67.3	%		60.9	%

In addition, three of the Company’s customers: Lam Research Corporation, Applied Materials, Inc. and ASM International, Inc., had accounts receivable balances that were individually greater than 10% of total accounts receivable as of September 25, 2020 and December 27, 2019, and in the aggregate approximately 59.1% and 66.7% of total accounts receivable, respectively.

Fair Value of Measurements — The Company measures its cash equivalents, contingent earn-out liabilities, pension obligation and common stock purchase obligation at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.

Level 3 — Unobservable inputs that are supported by little or no market activities.

Inventories — Inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of the Company’s products.

Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.

- 10 -

Property, Plant and Equipment, net — Property, plant and equipment are stated at cost, or, in the case of equipment under finance leases, the present value of future minimum lease payments at inception of the related lease. The Company also capitalizes interest on borrowings related to eligible capital expenditures. Capitalized interest is added to the cost of the qualified assets and depreciated. Depreciation and amortization are computed using the straight-line method over the lesser of the estimated useful lives of the assets or the terms of the leases. Useful lives range from three to fifty years. Direct costs incurred to develop software for internal use are capitalized and amortized over an estimated useful life of three or ten years. Costs related to the design or maintenance of internal use software are expensed as incurred. Capitalized internal use software is included in computer equipment and software.

Long-lived Assets — The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The Company assesses the fair value of the assets based on the amount of the undiscounted future cash flows that the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than the carrying value of the asset. If the Company identifies an impairment, the Company reduces the carrying value of the group of assets to comparable market values, when available and appropriate, or to its estimated fair value based on a discounted cash flow approach.

The Company assessed the useful lives of its long-lived assets, including property, plant and equipment as well as its intangible assets as of September 25, 2020 and concluded that no impairment was required.

Leases — The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement. When the Company determines the arrangement is a lease, or contains a lease, at lease inception, it then determines whether the lease is an operating lease or a finance lease. Operating and finance leases with lease terms of one year or greater result in the Company recording a right-of-use (ROU) asset and lease liability on its balance sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are initially recognized based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable or when the implicit interest rate is not readily determinable, the Company uses its incremental borrowing rate. The incremental borrowing rate is not a commonly quoted rate and is derived through a combination of inputs including the Company’s credit rating and the impact of full collateralization. The incremental borrowing rate is based on the Company’s collateralized borrowing capabilities over a similar term of the lease payments. The Company utilizes the consolidated group incremental borrowing rate for all leases. The operating lease ROU asset also includes any lease payments made and excludes any lease incentives. Specific lease terms used in computing the ROU assets and lease liabilities may include options to extend or terminate the lease when the Company believes it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. As allowed by the guidance, the Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, other current liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheet. The Company’s finance leases at September 25, 2020 and December 27, 2019 were not significant.

Goodwill and Indefinite Lived Intangible Assets — Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. Intangible assets are presented at cost, net of accumulated amortization, and are amortized on either a straight-line method or on an accelerated method over their estimated future discounted cash flows. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.

Deferred Debt Issuance Costs — Debt issuance costs incurred in connection with obtaining debt financing are deferred and presented as a direct deduction from Bank Borrowings in the accompanying Condensed Consolidated Balance Sheets. Costs incurred in connection with revolving credit facilities and letter of credit facilities are deferred and presented as an offset to bank borrowings in the accompanying Condensed Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.

Defined Benefit Pension Plan — The Company has a noncontributory defined benefit pension plan covering substantially all of the employees of one of its foreign entities upon termination of their employee services. For further discussion of the Company’s defined benefit pension plan see Note 8 of Notes to the Condensed Consolidated Financial Statements.

Revenue Recognition — Revenue is recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company assesses collectability based on the credit worthiness of the customer and past transaction history. The Company performs on-going credit evaluations of customers and generally does not require collateral from customers.

- 11 -

Shipping and Handling Costs — Shipping and handling costs are included as a component of cost of revenues.

Research and Development Costs — Research and development costs are expensed as incurred.

Stock-Based Compensation Expense — The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives and certain employees. These equity-based awards include stock options, restricted stock awards and restricted stock units. The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price.

Government Subsidies — Government subsidies are recognized where there is reasonable assurance that the subsidy will be received and all attached conditions will be complied with. When the subsidy relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the subsidy relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. When the subsidy does not relate to specific expenses or assets, the income is accounted for in the period where there is reasonable assurance that the subsidy will be received.

Income Taxes — The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future state, federal, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. The Company continued to maintain a full valuation allowance on its federal and state deferred tax amounts as of September 25, 2020.

Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the Condensed Consolidated Statements of Operations as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a significant impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty.

Net Income per Share — Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive stock options and restricted stock using the treasury stock method, except when such shares are anti-dilutive. See Note 14 to the Company’s Condensed Consolidated Financial Statements.

Business Combinations — The Company recognizes assets acquired (including goodwill and identifiable intangible assets), liabilities assumed and noncontrolling interest at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.

Accounting Standard Not Yet Adopted

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis

- 12 -

through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of this new standard on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financing Reporting. This guidance provides temporary optional expedients and exceptions through December 31, 2022 to the U.S. GAAP guidance on contract modifications to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance was effective upon issuance. As a result, the Company adopted the guidance in the second quarter of fiscal 2020 and there was no financial impact on the Condensed Consolidated Financial Statements upon adoption.

2. BUSINESS COMBINATIONS

Dynamic Manufacturing Solutions, LLC (“DMS”)

On April 15, 2019, the Company purchased substantially all of the assets of DMS, a semiconductor weldment and solutions provider. Pursuant to the purchase agreement, the former owners of DMS were entitled to up to a maximum of $12.5 million of potential cash earn-out if the combined weldment business achieves certain gross profit and gross margin targets for the twelve months ended June 26, 2020. The fair value of the earn-out at the acquisition date was $1.5 million and was determined using a risk-adjusted earnings projection utilizing the Monte Carlo Simulation method. These inputs are not observable in the market and thus represent a Level 3 measurement as discussed in Note 1 of the Company’s Condensed Consolidated Financial Statements. The total purchase consideration of DMS for purposes of the Company’s purchase price allocation was determined to be $31.4 million, which includes the cash payment of $29.9 million and the fair value of the potential earn-out payments of $1.5 million.

During the second quarter of fiscal year 2020, DMS achieved the specified performance target of the earn-out, which resulted in the maximum payout of $12.5 million, which was paid in August 2020. The increase in fair value of $3.0 from $9.5 million at December 27, 2019 was recorded as other expense in the condensed consolidated statement of operations for the nine months ended September 25, 2020, respectively.

In the first quarter of fiscal year 2020, the Company completed the acquisition accounting and the valuation of the fair value of the assets acquired and the liabilities assumed. The following table summarizes the recognized amounts of assets acquired and liabilities assumed at the acquisition date:

Fair Market Values (in millions)
Accounts receivable	$	1.5
Inventories		8.9
Equipment and leasehold improvements		5.4
Goodwill		12.3
Purchased intangible assets		6.9
Other non-current assets		0.3
Total assets acquired		35.3
Accounts payable		(3.8	)
Other liabilities		(0.1	)
Total liabilities assumed		(3.9	)
Purchase consideration transferred	$	31.4

			Purchased
	Useful Life		Intangible Assets
	(In years)		(In millions)
Customer relationships		6	$	6.9

The results of operations for the three and nine months ended September 27, 2019 included operating activity for DMS since its acquisition date of April 15, 2019. The results of operations for the three and nine months ended September 25, 2020, included charges attributable to amortization of purchased intangible assets of $0.3 million and $0.9 million, respectively, and $0.3 million and $0.5 million for the three and nine months ended September 27, 2019, respectively, which are included in general and administrative expenses in the Condensed Consolidated Statements of Operations.

Restructuring

During the first quarter of fiscal year 2020, the Company made a strategic decision to fully integrate Quantum Global Technologies, LLC’s (“QGT”) corporate office responsibilities from Quakertown, PA to UCT’s corporate office in Hayward, CA. As a result, the Company recorded a restructuring charge of $1.9 million for the nine months ended September 25, 2020, in general and administrative expense, primarily related to employee severance as well as the impaired value of the facility lease and losses on sale of equipment.

4. FAIR VALUE MEASUREMENTS

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following table summarizes, for assets or liabilities measured at fair value, the respective fair value and the classification by level of input within the fair value hierarchy:

			Fair Value Measurement at
			Reporting Date Using
Description	September 25, 2020		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
(In millions)
Other liabilities:
Common stock purchase obligation	$	8.2	$	—	$	—	$	8.2
Pension obligation	$	5.2	$	—	$	—	$	5.2

			Fair Value Measurement at
			Reporting Date Using
Description	December 27, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
(In millions)
Other liabilities:
Contingent earn-out liability	$	9.5	$	—	$	—	$	9.5
Common stock purchase obligation	$	6.8	$	—	$	—	$	6.8
Pension obligation	$	4.4	$	—	$	—	$	4.4

The fair value of the contingent earn-out liability was transferred to Level 1 from Level 3 due to the achievement of the maximum amount of the earn-out as defined in the purchase agreement with DMS dated April 15, 2019. Fair value adjustments were noncash, and therefore did not impact the Company’s liquidity or capital resources. Qualitative information about Level 3 fair value measurements are primarily as follows:

	September 25,		Valuation	Unobservable
	2020		Techniques	Input	Range
(Dollars in millions, except rate/multiple)
Common stock purchase obligation	$	8.2	Discounted cash flow	Revenue multiple		1.5
				EBITDA Multiple		5.5
				Discount rate	25.0%
Pension obligation	$	5.2	Projected unit credit method	Discount rate	2.0%
				Rate on return	1.7%
				Salary increase rate	4.5%

Following is a summary of the Level 3 activity:

(In millions)	Common stock Purchase obligation		Pension obligation
As of December 27, 2019	$	6.8	$	4.4
Fair value adjustments	1.4		0.8
As of September 25, 2020	$	8.2	$	5.2

5. GOODWILL AND INTANGIBLE ASSETS

The Company’s methodology for allocating the purchase price relating to an acquisition is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the consideration transferred over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed.

- 15 -

To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company concludes it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, the Company does not proceed to perform a quantitative impairment test. If the Company concludes it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative goodwill impairment test will be performed by comparing the fair value of each reporting unit to its carrying value. A quantitative impairment analysis, if necessary, considers the income approach, which requires estimates of the present value of expected future cash flows to determine a reporting unit’s fair value. Significant estimates include revenue growth rates and operating margins used to calculate projected future cash flows, discount rates, and future economic and market conditions. A goodwill impairment charge is recognized for the amount by which the reporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The process of evaluating the potential impairment of goodwill and intangible assets requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends and lower projections of profitability that may impact future operating results.

Details of aggregate goodwill of the Company are as follows:

(In millions)	SPS		SSB		Total
Balance at December 27, 2019	$	97.6	$	73.5	$	171.1
Adjustments	—		—		—
Balance at September 25, 2020	$	97.6	$	73.5	$	171.1

Intangible Assets

Intangible assets are generally recorded in connection with a business acquisition. The Company evaluates the useful lives of its intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization. In addition, the Company reviews indefinite lived intangible assets for impairment when events or changes in circumstances indicate their carrying value may not be recoverable and tests definite lived intangible assets at least annually for impairment. Management considers such indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure.

Details of intangible assets were as follows:

		As of September 25, 2020							As of December 27, 2019
		Gross							Gross
	Useful Life	Carrying		Accumulated			Carrying		Carrying		Accumulated			Carrying
(Dollars in millions)	(in years)	Amount		Amortization			Value		Amount		Amortization			Value
Customer relationships	6 - 10	$	119.4	$	(47.9	)	$	71.5	$	119.4	$	(39.8	)	$	79.6
Tradename	4 - 6*		27.0		(10.8	)		16.2		27.0		(8.1	)		18.9
Intellectual property/know-how	7 - 12		13.9		(9.4	)		4.5		13.9		(8.4	)		5.5
Recipes	20		73.2		(7.6	)		65.6		73.2		(4.9	)		68.3
Standard operating procedures	20		8.6		(0.9	)		7.7		8.6		(0.6	)		8.0
Total		$	242.1	$	(76.6	)	$	165.5	$	242.1	$	(61.8	)	$	180.3

* The Company concluded that the UCT tradename intangible asset amounting to $9.0 million has an indefinite life and is therefore not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

- 16 -

The Company amortizes its intangible assets on a straight-line or accelerated basis over the estimated economic life of the assets. Amortization expense was approximately $4.9 million and $5.1 million for the three months ended September 25, 2020 and September 27, 2019, respectively, and was approximately $14.8 million and $15.0 million for the nine months ended September 25, 2020 and September 27, 2019. Amortization expense related to QGT’s recipes and standard operating procedures is charged to cost of revenues and the remainder is charged to general and administrative expense. As of September 25, 2020, future estimated amortization expense is expected to be as follows:

	Amortization
(In millions)	Expense
2020 (remaining in year)	$	4.9
2021		19.6
2022		19.3
2023		14.2
2024		14.0
Thereafter		84.5
Total	$	156.5

6. BORROWING ARRANGEMENTS

In August 2018, the Company entered into a credit agreement with Barclays Bank that provided a Term Loan, a Revolving Credit Facility, and a Letter of Credit Facility (the “Credit Facilities”). UCT and certain of its subsidiaries have agreed to secure all of their obligations under the Credit Facilities by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations). In August 2018, the Company borrowed $350.0 million under the Term Loan and used the proceeds, together with cash on hand, to finance the acquisition of QGT and to refinance its previous credit facilities.

The Term Loan has a maturity date of August 27, 2025, with monthly interest payments in arrears, quarterly principal payments of 0.625% of the original outstanding principal balance payable beginning January 2019, with the remaining principal paid upon maturity. The Term Loan accrues interest at a rate equal to a base LIBOR rate determined by reference to the London interbank offered rate for dollars, plus 4.5% (subject to certain adjustments quarterly based upon the Company’s consolidated leverage ratio).  At September 25, 2020, the Company had an outstanding amount under the Term Loan of $287.8 million, gross of unamortized debt issuance costs of $8.3 million.

The Revolving Credit Facility has an initial available commitment of $65.0 million and a maturity date of August 27, 2023. The Company pays a quarterly commitment fee in arrears equal to 0.25% of the average daily available commitment outstanding. In March 2020, the Company drew $40.0 million under the Revolving Credit Facility to fund operations. In September 2020, the revolver balance of $40.0 million was repaid in full.

As of September 25, 2020, the interest rate on the outstanding Term Loan was 4.7%. After December 31, 2021, LIBOR will officially be phased out. The Company will work with its bank to determine alternative risk-free rates.

The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of at least 1.25 to 1.00, and a consolidated leverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of no greater than 3.75 to 1.00. The Company was in compliance with all financial covenants as of the quarter ended September 25, 2020.

The Letter of Credit Facility has an initial available commitment of $50.0 million and a maturity date of August 27, 2023. The Company pays quarterly in arrears a fee equal to 2.5% (subject to certain adjustments as per the Term Loans) of the dollar equivalent of all outstanding letters of credit, and a fronting fee equal to 0.125% of the undrawn and unexpired amount of each letter of credit. As of September 25, 2020, the Company had $2.4 million of outstanding letters of credit with beneficiaries such as landlords of certain facility leases and government agencies making up the majority of the outstanding balance. The remaining available commitments are $47.6 million on the Letter of Credit Facility and $65.0 million on the Revolving Credit Facility.

The Company’s subsidiary in the Czech Republic, UCT Fluid Delivery Solutions s.r.o., (FDS) has a revolving credit facility which renews annually at the end of the fiscal second quarter. As of September 25, 2020, FDS had an outstanding amount of $0.3 million with an interest rate of 0.8% under the revolving credit facility.

In the quarter ended September 25, 2020, Cinos China amended its existing Credit Agreement and entered into two additional Credit Agreements with a local bank that provide Revolving Credit Facilities for a total available commitment of $3.5 million with various

- 17 -

maturity dates through September 23, 2022 and interest rates ranging from 1.9% to 4.1%. As of September 25, 2020, Cinos China had an outstanding amount of $ 0.3 million with an interest rate of 1.9% under these Credit Agreements.

Cinos Korea has Credit Agreements with various banks that provide Revolving Credit Facilities for a total available commitment of 1.6 billion Korean Won (approximately $1.4 million) with annual renewals beginning from April 2021 through June 2021 and interest rates ranging from 1.4% - 5.4%.  During the nine months ended September 25, 2020, borrowings under these Revolving Facilities were insignificant and no amounts were outstanding as of September 25, 2020.

As of September 25, 2020, the Company’s total bank debt was $280.1 million, net of unamortized debt issuance costs of $8.3 million. As of September 25, 2020, the Company had $65.0 million and $9.3 million available to borrow on its revolving credit facilities in the U.S. and Czech Republic, respectively.

The fair value of the Company’s long term-debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The Company’s carrying value approximates fair value for the Company’s long-term debt.

7. INCOME TAX

The Company's effective tax rate was 16.0% and 81.4% for the three months ended September 25, 2020 and September 27, 2019, respectively, and 20.6% and 80.5% for the nine months ended September 25, 2020 and September 27, 2019, respectively. The Company’s income tax provision was $4.8 million and $3.9 million for the three months ended September 25, 2020 and September 27, 2019, respectively, and $15.0 million and $8.2 million for the nine months ended September 25, 2020 and September 27, 2019, respectively. The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results in jurisdictions which are taxed at different rates and the impact of losses in jurisdictions with full federal and state valuation allowances.  

Company management continuously evaluates the need for a valuation allowance and, as of September 25, 2020, concluded that a full valuation allowance on its federal and state deferred tax assets was still appropriate.

The Company provides for U.S. income taxes on the earnings of its foreign subsidiaries to the extent required by the Tax Cuts and Jobs Act (TCJA). However, the Company does not provide for withholding taxes on that portion of the undistributed earnings of its foreign subsidiaries that it intends to reinvest indefinitely outside the U.S. In prior years, the Company determined that a portion of the current year earnings of one of its China subsidiaries may be remitted in the future to one of its foreign subsidiaries outside of China and, accordingly, the Company provided for the related withholding taxes in its Condensed Consolidated Financial Statements. The Company remitted a portion of those earnings during 2019 and may remit the remainder of the earnings on which withholding taxes have already been accrued but does not currently expect to remit any other Chinese earnings. The Company has also historically remitted earnings from its Singapore subsidiary to the U.S. and may do so again in the future. However, the Company has not accrued for withholding taxes on Singapore earnings as the country does not impose a withholding tax. If the Company changes its intent to reinvest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed than the previous anticipated remaining unremitted foreign earnings, the Company could be required to accrue or pay foreign taxes on some or all of these undistributed earnings. As of September 25, 2020, the Company had undistributed earnings of foreign subsidiaries that are considered indefinitely invested outside of the U.S. of approximately $212.6 million. It is not practicable to determine the tax liability that might be incurred if these earnings were to be distributed.

As of September 25, 2020 and September 27, 2019, the Company’s gross liability for unrecognized tax benefits, excluding interest, was $1.0 million for both periods. Although it is possible that some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was enacted. The CARES Act includes changes to tax provisions that benefit business entities and makes certain technical corrections to the 2017 TCJA. Tax relief measures for businesses include modifications to limitations on the deductibility of net operating losses (NOLs) such as a five-year carryback of NOLs incurred in tax years beginning in 2018, 2019 or 2020, and removal of the 80% of taxable income limitation on NOL deductions for tax years beginning before January 1, 2021.  Other tax relief measures include modifications to the limitations on the deductibility of interest for tax years beginning in 2019 and 2020, acceleration of alternative minimum tax credit refunds, payroll tax relief, and a technical correction to the TCJA that would provide accelerated depreciation deductions for qualified improvement property. The CARES Act also provides other non-tax benefits to assist those impacted by the COVID-19 pandemic. The Company has evaluated the impact of the CARES Act and determined that there was no significant impact to the income tax provision for the three and nine months ended September 25, 2020.  The Company also does not expect the provisions of the CARES Act to result in a significant cash benefit.  However, the Company continues to monitor and evaluate the regulatory and interpretive guidance related to the CARES Act.

8. RETIREMENT PLANS

Defined Benefit Pension Plan

Cinos Korea has a noncontributory defined benefit pension plan covering substantially all of its employees upon their retirement. The benefits are based on expected years of service and average compensation. The net period costs are recognized as employees render the services necessary to earn the postretirement benefits.  The Company records annual amounts relating to the pension plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates.  The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current and expected rates of return and trends when it is appropriate to do so.  The effect of modifications to those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using the corridor method.  The Company believes that the assumptions utilized in recording its obligations under the plan are reasonable based on its experience and market conditions.  

As of September 25, 2020, the benefit obligation of the plan is $8.7 million and the fair value of the benefit plan assets, which are invested in several fixed deposit accounts with a bank is $5.1 million.  As of September 25, 2020, the unfunded balance of the plan of $3.6 million has been accrued for by the Company and is included in other long-term liabilities.  Amounts recognized in accumulated other comprehensive income as of September 25, 2020 is $0.5 million.  The contributions to the plan by the Company and its subsidiaries during the year ended September 25, 2020 was $1.4 million. The benefits expected to be paid from the pension plan in each year from 2020-2024 are $0.2 million, $1.1 million, $2.2 million, $0.9 million and $1.0 million, respectively.  The aggregate benefits expected to be paid in the five years from 2025-2029 are $4.6 million.

Employee Savings and Retirement Plan

The Company sponsors a 401(k) savings and retirement plan (the “401(k) Plan”) for all U.S. employees who meet certain eligibility requirements. Participants could elect to contribute to the 401(k) Plan, on a pre-tax basis, up to 25% of their salary to a maximum of $19,500. The Company may make matching contributions of up to 3% of employee contributions based upon eligibility. The Company made approximately $0.6 million and $1.9 million discretionary employer contributions to the 401(k) Plan in the three and nine months ended September 25, 2020, respectively, and $0.3 million and $0.9 million for the three and nine months ended September 27, 2019, respectively.  

9. COMMITMENTS AND CONTINGENCIES

Commitment

The Company had commitments to purchase inventory totaling approximately $179.4 million as of September 25, 2020.

Contingency

From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims cannot be predicted with certainty, the Company has not had a history of outcomes to date that have been significant to the Condensed Consolidated Statements of Operations and does not believe that any of these proceedings or other claims will have a significant adverse effect on its consolidated financial condition, results of operations or cash flows.

10. STOCKHOLDERS’ EQUITY AND NONCONTROLLING INTERESTS

Noncontrolling Interests

QGT owns 51.0% of the outstanding shares of Cinos, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and through a 60.0% interest in Cinos China. QGT is obligated to purchase shares held by another shareholder of Cinos Korea representing a 35.0% interest. QGT accounted for this unconditional obligation as an assumed liability and derecognized any noncontrolling interest related to the 35.0%, which brings its controlling interest up to 86.0%.  

The carrying value of the remaining 14.0% interest held by another shareholder in Cinos Korea and the 40.0% interest in the Cinos joint venture are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The fair values of the noncontrolling interests were estimated based on the values of Cinos Korea and Cinos China on a 100.0% basis. The values were calculated based on the pro-rata portion of total forecasted QGT earnings before interest expense, taxes, depreciation and amortization ("EBITDA") contributed by each entity.

The Company is obligated to purchase shares owned by a Cinos Korea shareholder. A certain number of shares would be purchased at a fixed price per share, while the other remaining shares would be purchased based on the greater of the then fair value of the stock

- 19 -

and the fixed price per share (floor). The Company has a firm obligation to purchase the shares and a call option, while the other shareholder has a put option. As of September 25, 2020, the fair value of the obligation is $8.2 million which has been recorded as a non-current liability in the accompanying consolidated balance sheets and represents a Level 3 measurement as discussed in Note 4 of the Company’s Consolidated Financial Statements. The agreement with Cinos Korea allows for the common stock purchase obligation to become due in December 2022, and once completed, the Company will own 86.0% of Cinos Korea.

11. EMPLOYEE STOCK PLANS

The Company grants stock awards in the form of restricted stock units (RSUs) and performance stock units (PSUs) to its employees as part of the Company’s long term equity compensation plan. These stock awards are granted to employees with a unit purchase price of zero dollars and typically vest over three years, subject to the employee’s continued service with the Company and, in the case of PSUs, subject to achieving certain performance goals. The Company also grants common stock to its board members in the form of restricted share awards (RSAs), which vest on the earlier of 1) the next Annual Shareholder Meeting, or 2) 365 days from date of grant.

Stock-based compensation expense includes compensation costs related to estimated fair values of awards granted. The estimated fair value of the Company’s equity-based awards, net of expected forfeitures, is amortized on a straight-line basis over the awards’ vesting period and is adjusted for subsequent changes in estimated forfeitures related to all equity-based awards and performance as it relates to PSUs.

The following table shows the Company’s stock-based compensation expense included in the Condensed Consolidated Statements of Operations:

	Three Months Ended						Nine Months Ended
	September 25,			September 27,			September 25,			September 27,
(In millions)	2020			2019			2020			2019
Cost of revenues (1)	$	0.4		$	0.6		$	1.4		$	1.8
Research and development		-			0.1			0.1			0.3
Sales and marketing		0.3			0.3			0.9			0.9
General and administrative		2.6			2.3			7.1			6.1
		3.3			3.3			9.5			9.1
Income tax benefit		(0.5	)		(2.7	)		(1.9	)		(7.3	)
Stock-based compensation expense, net of tax	$	2.8		$	0.6		$	7.6		$	1.8

(1) Stock-based compensation expense capitalized in inventory for the three and nine months ended September 25, 2020 and for the three and nine months ended September 27, 2019 was not significant.

For purposes of determining compensation expense related to these RSUs, the fair value is determined based on the closing market price of the Company’s common stock on the date of award.

There were 21.2 thousand RSUs granted during the quarter ended September 25, 2020, with a weighted average fair value of $22.39 per share. For the nine months ended September 25, 2020, 0.8 million RSUs were granted with a weighted average fair value of $18.32 per share.

For the nine months ended September 25, 2020, 0.1 million vested shares were withheld to satisfy withholding tax obligations, resulting in the net issuance of 0.6 million shares.

As of September 25, 2020, approximately $18.4 million of stock-based compensation cost, net of estimated forfeitures, related to RSUs and PSUs remains to be amortized over a weighted average period of 1.9 years. As of September 25, 2020, a total of 1.7 million RSUs and PSUs remain outstanding with an aggregate intrinsic value of $35.9 million and a weighted average remaining contractual term of 1.3 year.

As of September 25, 2020, a total of 44,107 shares of RSAs were outstanding. The total unamortized expense of the Company’s unvested restricted stock awards as of September 25, 2020 was $0.6 million.

- 20 -

The following table summarizes the Company’s combined RSU, PSU and RSA activity for the nine months ended September 25, 2020:

(In millions)	Shares			Aggregate Fair Value
Unvested RSUs, PSUs and RSAs at December 27, 2019		1.8		$	41.9

Unvested RSUs, PSUs and RSAs as of September 25, 2020		1.8		$	36.8
Vested and expected to vest RSUs, PSUs and RSAs as of September 25, 2020		1.8		$	36.8

12. REVENUE RECOGNITION

The Company sells its products and services primarily to customers in the semiconductor capital equipment industry. The Company’s revenues are highly concentrated, and we are therefore highly dependent upon a small number of customers. Typical payment terms with our customers range from thirty to sixty days.

The Company’s SPS segment provides warranty on its products for a period of up to two years and provides for warranty costs at the time of sale based on historical activity. Determination of the warranty reserve requires the Company to make estimates of product return rates and expected costs to repair or replace the products under warranty. If actual return rates and/or repair and replacement costs differ significantly from these estimates, adjustments to recognize additional cost of revenues may be required in future periods. The warranty reserve is included in other current liabilities on the Condensed Consolidated Balance Sheets and is not considered significant.

The Company’s products are manufactured at our facilities in the U.S.A., China, Singapore and the Czech Republic. The Company provides services from operations in the U.S.A., Singapore, United Kingdom, Israel, Taiwan, South Korea, and China. Sales to customers are initiated through a purchase order and are governed by our standard terms and conditions, written agreements, or both. Revenue is recognized when performance obligations under the terms of an agreement with a customer are satisfied; generally, this occurs with the transfer of control of the products or when the Company provides the services. Transfer of control occurs at a specific point-in-time. Based on the enforceable rights included in our agreements or prevailing terms and conditions, products produced by the Company without an alternative use are not protected by an enforceable right of payment that includes a reasonable profit throughout the duration of the agreement. Consignment sales are recognized in revenue at the earlier of the period that the goods are consumed or after a period of time subsequent to receipt by the customer as specified by terms of the agreement, provided control of the promised goods or services has transferred.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value-add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Certain of our customers may receive cash-based incentives, such as rebates or credits, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenues recognized. As of September 25, 2020, an accrual for unpaid customer rebates of $2.4 million was included in accrued expenses on the Company’s Consolidated Balance Sheet. The Company's disaggregated revenues are by segment.

The Company’s principal markets include America, Asia and Europe. The Company’s foreign operations are conducted primarily through its subsidiaries in China, Singapore, Israel, Taiwan, South Korea, the United Kingdom and the Czech Republic. Revenues by geographic area are categorized based on the customer’s location to which the products were shipped or services performed. The following table sets forth revenue by geographic area (in millions):

	Three Months Ended				Nine Months Ended
	September 25,		September 27,		September 25,		September 27,

15. REPORTABLE SEGMENTS

The Company operates and reports results for two operating segments: SPS and SSB. These segments are organized primarily by the nature of the products and service they provide. The Company’s Chief Executive Officer (chief operating decision maker) views and evaluates operations based on the results of each of the reportable segments. The following table describes each segment:

Segment	Product or Services	Markets Served	Geographic Areas
SPS	Assembly Weldments Machining Fabrication	Semiconductor	United States Asia Europe
SSB	Cleaning Analytics	Semiconductor	United States Asia Europe

The Company uses segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. Segment profit or loss is defined as income or loss from continuing operations before other income and income taxes included in the accompanying condensed consolidated statements of operations.

Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented.

16. GOVERNMENT SUBSIDIES

From April through September of the current year, the Singapore government announced a series of relief measures for wages paid to local employees with the purpose of supporting employers during this period of economic uncertainty related to the COVID-19 pandemic, including the co-funding of wages incurred by local employers for nine months ending December 31, 2020. The Company

- 23 -

estimated that the total amount of these subsidies will be $3.2 million of which $ 1.1 million and $1.8 million was recorded during the three and nine months ended September 25, 2020, respectively, as an offset to cost of revenues.

The Company also received unconditional subsidies of $0.6 million from the China government during the nine months ended September 25, 2020. These subsidies were recognized as other income in the condensed consolidated statements of operations. In addition, the China government reduced the cost of certain social insurance requirements and also subsidized rent which benefited the Company by $0.4 million and $1.1 million during the three and nine months ended September 25, 2020, respectively. These subsidies were recorded as an offset to cost of revenues and other operating expenses

Overview

Ultra Clean Holdings, Inc. is a leading developer and supplier of critical subsystems, ultra-high purity cleaning and analytical services primarily for the semiconductor industry. We report our results for two segments: Semiconductor Products and Solutions (“SPS”) and Semiconductor Services Business (“SSB”). Our SPS business primarily designs, engineers and manufactures production tools, modules and subsystems for the semiconductor and display capital equipment markets.  SPS products include chemical delivery modules, frame assemblies, gas delivery systems, fluid delivery systems, precision robotics, process modules as well as other high-level assemblies. Our SSB business provides ultra-high purity outsourced parts cleaning, process tool part recoating, surface encapsulation and high sensitivity micro contamination analysis primarily for the semiconductor device makers and wafer fabrication (WFE) equipment markets.

We ship a majority of our products and provide most of our services to U.S. registered customers with locations both in and outside the U.S. In addition to U.S. manufacturing and service operations, we manufacture products and provide parts cleaning and other related services in our Asian and European facilities to support local and U.S. based customers. We conduct our operating activities primarily through our subsidiaries, Ultra Clean Technology Systems and Service, Inc., American Integration Technologies, LLC, Ultra Clean Micro-Electronics Equipment (Shanghai) Co., Ltd., Ultra Clean Asia Pacific, Pte, Ltd., UCT Thermal Solutions, Inc., UCT Fluid Delivery Solutions s.r.o. (FDS), Quantum Global Technologies, LLC (“QGT”) and Dynamic Manufacturing Solutions, LLC ("DMS").

Over the long-term, we believe the semiconductor market we serve will continue to grow due to multi-year industry inflections creating demand from a broad range of drivers including mobile demand driven by 5G, new CPU architectures which are enabling higher performance servers, and cloud, AI and machine learnings. We also believe that semiconductor equipment OEMs are increasingly relying on partners like UCT to fulfill their expanding capacity requirements.

Impact of COVID-19 on Our Business

We are subject to risks and uncertainties as a result of the COVID-19 pandemic. Our financial results for the three months ended September 25, 2020 represent our second full quarter of operations during the COVID-19 pandemic. The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, as the response to the pandemic is ongoing and information is constantly evolving. Furthermore, the negative impact of the COVID-19 pandemic on economies worldwide has been and continues to be severe.

- 25 -

The severity of the impact of the COVID-19 pandemic on our business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on our customers, all of which are uncertain and cannot be predicted. Our future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the impact of any initiatives or programs that we may undertake to address financial and operations challenges faced by our customers. As of the date of issuance of these condensed consolidated financial statements, the extent to which the COVID-19 pandemic may materially impact our financial condition, liquidity, or results of operations is uncertain. We will continue to actively monitor the situation and take further actions that may alter our business operations as may be required by federal, state or local authorities or if we determine are in the best interests of our employees, customers, suppliers and shareholders. While we are unable to determine or predict the nature, duration or scope of the overall impact the COVID-19 pandemic will have on our business, results of operations, liquidity or capital resources, we believe that it is important to share where our company stands today, how our response to COVID-19 is progressing and how our operations and financial condition may change as the fight against COVID-19 progresses. For additional details, see the discussion in the Risk Factors section.

Critical Accounting Estimates

Our Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure at the date of our Condensed Consolidated Financial Statements. From time to time, we evaluate our estimates and judgments, including those related to sales, inventories, goodwill and intangible assets, stock compensation and income taxes. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. We consider certain accounting policies related to inventory valuation, accounting for income taxes, business combinations, valuation of intangible assets and goodwill, accounting for pension obligations and equity incentives to employees to be critical policies due to the estimates and judgments involved in each.

There have been no significant changes to our critical accounting policies, significant judgments and estimates disclosed in our Annual Report on Form 10-K subsequent to December 27, 2019.  For further information on our critical and other significant accounting policies and estimates, see Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended December 27, 2019, as filed with the SEC.

Results of Operations

On a geographic basis, revenues represent products shipped from or services performed at our U.S. and international locations. For the three and nine months ended September 25, 2020, U.S. revenues increased, driven by 2 factors.  The first of these was an overall increase in semiconductor industry demand in the U.S.  The second factor relates to the April, 2019 acquisition of DMS, whose customers are primarily U.S. based. For the three and nine months ended September 25, 2020, international revenue increased in absolute terms and as a percentage of total revenue, primarily due to the overall higher semiconductor and semiconductor capital equipment demand outside of the U.S..

SSB as a percentage of total SSB revenues		65.5	%		67.6	%					64.5	%		67.1	%

Total cost of revenues increased $81.9 million and $175.5 million for the three and nine months ended September 25, 2020, respectively, due to higher demand for both SPS products and SSB services.

SPS cost of revenues consists of purchased materials, direct labor and manufacturing overhead. SPS cost of revenues increased $73.5 million for the three months ended September 25, 2020 compared to the same period in the prior year, due to higher volume of sales driving increased material costs of $64.7 million, higher direct labor spending of $1.0 million and higher overhead costs of $7.8 million. SPS cost of revenues increased $161.9 million for the nine months ended September 25, 2020 compared to the same period in the prior year, due to higher volume of sales driving increased material costs of $151.5 million, higher direct labor spending of $6.4 million and higher overhead costs of $4.0 million.

SSB cost of revenues consists of direct labor, manufacturing overhead and materials (such as chemicals, gases and consumables). SSB cost of revenues increased $8.4 million in the three months ended September 25, 2020 compared to the same period in the prior year driven by higher volumes of service orders, resulting in an increase in labor costs of $4.4 million (the largest component of SSB’s total cost of revenues), higher material costs of $3.3 million and higher overhead costs of $0.7 million driven by higher service orders. SSB cost of revenues increased $13.6 million for the nine months ended September 25, 2020 compared to the same period in the prior year driven by higher volumes of service orders, resulting in increases in labor costs of $6.8 million and higher material costs of $4.7 million and higher depreciation expense of $2.2 million as a result of an increase in capital assets.

Interest expense decreased in the three and nine months ended September 25, 2020, compared to the same periods in the prior year, due to a lower average debt balance, lower interest rates resulting from lower LIBOR rates and higher interest expense capitalized on borrowings related to qualified capital expenditures.

Other income (expense), net decreased in the three months ended September 25, 2020, compared to the same period in the prior year, due to the absence of the decrease in fair value of the contingent earn-out liability of $2.4 million related to the QGT acquisition and the $1.0 million business interruption insurance income, which were recorded in the same period of the prior year.

Other income (expense), net decreased in the nine months ended September 25, 2020, compared to the same period in the prior year, due to increases in the fair value of the contingent earn-out liability related to the DMS acquisition and of the common stock purchase obligation of $2.7 million and $1.4 million, respectively. These other expenses were partially offset by other income of $0.6 million of government subsidies received by the Company’s subsidiary in China and by $0.6 million of insurance proceeds pertaining to the Cinos fire and the absence of the $3.9 million decrease in fair value of the contingent earn out related to the QGT acquisition and the $1.0 million business interruption insurance income, which were recorded in the same period of the prior year.

Effective tax rate		16.0	%		81.4	%					20.6	%		80.5	%

The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results in jurisdictions which are taxed at different rates and the impact of losses in jurisdictions with full federal and state valuation allowances.

Company management continuously evaluates the need for a valuation allowance on its deferred tax assets and, as of September 25, 2020, concluded that a full valuation allowance on its federal and state deferred tax assets remained appropriate.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was enacted and signed into law and GAAP requires recognition of the tax effects of new legislation during the reporting period that includes the enactment date.  The CARES Act includes changes to tax provisions that benefit business entities and makes certain technical corrections to the 2017 TCJA. Tax relief measures for businesses include modifications to limitations on the deductibility of net operating losses (NOLs) such as a five-year carryback of NOLs incurred in tax years beginning in 2018, 2019 or 2020, and removal of the 80% of taxable income limitation on NOL deductions for tax years beginning before January 1, 2021.  Other tax relief measures include modifications to the limitations on the deductibility of interest for tax years beginning in 2019 and 2020, acceleration of alternative minimum tax credit refunds, payroll tax relief, and a technical correction to the TCJA that would provide accelerated depreciation deductions for qualified improvement property. The CARES Act also provides other non-tax benefits to assist those impacted by the COVID-19 pandemic. The Company has evaluated the impact of the CARES Act and determined that there was no significant impact to the income tax provision for the three and nine months ended September 25, 2020.  The Company also does not expect the provisions of the CARES Act to result in a significant cash benefit.  However, the Company continues to monitor and evaluate the regulatory and interpretive guidance related to the CARES Act.

Liquidity and Capital Resources

Cash and cash Equivalents

The following table summarizes our cash and cash equivalents:

	September 25,		December 27,
(In millions)	2020		2019		Increase
Total cash and cash equivalents	$	176.1	$	162.5	$	13.6

	Nine Months Ended
	September 25,			September 27,
(In millions)	2020			2019
Net cash flow provided by (used in):
Operating activities	$	52.9		$	89.1
Investing activities		(19.9	)		(39.8	)
Financing activities		(18.6	)		(31.3	)
Effects of exchange rate changes on cash and cash equivalents		(0.8	)		(3.4	)
Net increase in cash and cash equivalents	$	13.6		$	14.6

Our primary cash inflows and outflows were as follows:

• In the nine months ended September 25, 2020, we generated net cash from operating activities of $52.9 million compared to $89.1 million in the nine months period ended September 27, 2019. The $36.2 million decrease in net cash from operating activities was driven by a $103.1 million decrease in the net change from operating assets and liabilities offset by an $11.2 million increase from non-cash items and a $55.7 million increase in net income.

• The major contributors to the net change in operating assets and liabilities, net of effects of acquisition, in the nine months ended September 25, 2020 were as follows:

o Accounts receivable increased $32.7 million primarily due to the increase in revenues in fiscal 2020 and the timing of collections.

o Inventories increased $2.9 million due primarily to the customer demand outlook in 2020.

o Accounts payable decreased $21.9 million, accrued compensation and related benefits increased $5.9 million, income taxes payable increased $3.2 million and other liabilities decreased $2.5 million, primarily due to the timing of payments.

• In the nine months ended September 25, 2020, net cash used in investing activities was $19.9 million compared to $39.8 million in the nine months ended September 27, 2019. The change is primarily due to the acquisition of DMS in April 2019 offset by more purchases of property, plant and equipment in fiscal 2020.

• In the nine months ended September 25, 2020, net cash used in financing activities was $18.6 million compared to net cash used of $31.3 million in the nine months ended September 27, 2019. The change is mainly due to timing of payments on bank borrowings.

We have required capital to fund our working capital needs, satisfy our debt obligations, maintain our equipment, purchase new capital equipment and make strategic acquisitions from time to time. As of September 25, 2020, we had cash of $176.1 million

- 30 -

compared to $162.5 million as of December 27, 2019. Our cash and cash equivalents, cash generated from operations and amounts available under our revolving line of credit described below were our principal sources of liquidity as of September 25, 2020.

We anticipate that our existing cash and cash equivalents balance and operating cash flow will be sufficient to service our indebtedness and meet our working capital requirements and technology development projects for at least the next twelve months. The adequacy of these resources to meet our liquidity needs beyond that period will depend on our growth, the size and number of any acquisitions, the state of the worldwide economy, our ability to meet our financial covenants with our credit facility, the cyclical expansion or contraction of the semiconductor capital equipment industry and the other industries we serve and capital expenditures required to meet possible increased demand for our products.

In order to expand our business or acquire additional complementary businesses or technologies, we may need to raise additional funds through equity or debt financings. If required, additional financing may not be available on terms that are favorable to us, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, our stockholders’ equity interest will be diluted and these securities might have rights, preferences and privileges senior to those of our current stockholders. We may also require the consent of our new lenders to raise additional funds through equity or debt financings. No assurance can be given that additional financing will be available or that, if available, such financing can be obtained on terms favorable to our stockholders and us.

In prior years, we determined that a portion of the current year and future year earnings of one of our China subsidiaries may be remitted in the future to one of our foreign subsidiaries outside of China and, accordingly, we provided for the related withholding taxes in our Condensed Consolidated Financial Statements. As of September 25, 2020, we had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $212.6 million. As of September 25, 2020, we have cash of approximately $149.9 million in our foreign subsidiaries.

Borrowing Arrangements

The following table summarizes our borrowings:

	September 25, 2020
(Dollars in millions)	Amount		Interest Rate
U.S. Term Loan	$	287.8		4.7	%
FDS Revolving Credit Facility		0.3		0.8	%
Cinos China Term Loan		0.3		1.9	%
	$	288.4

In August 2018, we entered into a credit agreement with Barclays Bank that provided a Term Loan, a Revolving Credit Facility, and a Letter of Credit Facility (the “Credit Facilities”). We and some of our subsidiaries have agreed to secure all of their obligations under the Credit Facilities by granting a first priority lien in substantially all of our respective personal property assets (subject to certain exceptions and limitations). In August 2018, we borrowed $350.0 million under the Term Loan and used the proceeds, together with cash on hand, to finance the acquisition of QGT and to refinance our previous credit facilities.

The Term Loan has a maturity date of August 27, 2025, with monthly interest payments in arrears, quarterly principal payments of 0.625% of the original outstanding principal balance payable beginning January 2019, with the remaining principal paid upon maturity. The Term Loan accrues interest daily at a rate equal to a base LIBOR rate determined by reference to the London interbank offered rate for dollars, plus 4.5% (subject to certain adjustments quarterly based upon the Company’s consolidated leverage ratio). As of September 25, 2020, we had an outstanding amount under the Term Loan of $287.8 million, gross of unamortized debt issuance costs of $8.3 million.

The Revolving Credit Facility has an initial available commitment of $65.0 million and a maturity date of August 27, 2023. We pay a quarterly commitment fee in arrears equal to 0.25% of the average daily available commitment outstanding. During the first quarter of 2020 we drew $40.0 million under the Revolving Credit Facility to fund operations. In September 2020, the revolver balance of $40.0 million was repaid in full.

As of September 25, 2020, interest rates on the outstanding Term Loan was 4.7%. After December 31, 2021, LIBOR will officially be phased out. We will work with our bank to determine alternative risk-free rates.

The Credit Agreement requires that we maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of at least 1.25 to 1.00, and a consolidated leverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of no greater than 3.75 to 1.00. We were in compliance with all covenants for the quarter ended September 25, 2020.

- 31 -

The Letter of Credit Facility has an initial available commitment of $50.0 million and a maturity date of August 27, 2023. We pay quarterly in arrears a fee equal to 2.5% (subject to certain adjustments as per the Term Loans) of the dollar equivalent of all outstanding letters of credit, and a fronting fee equal to 0.125% of the undrawn and unexpired amount of each letter of credit. As of September 25, 2020, we had $2.4 million of outstanding letters of credit with beneficiaries such as landlords of certain facility leases and government agencies making up the majority of the outstanding balance. The remaining available commitments are $47.6 million on the Letter of Credit Facility and $65.0 million on the Revolving Credit Facility.

As of September 25, 2020, FDS had an outstanding amount under a revolving credit facility of $0.3 million with an interest rate of 0.8%.

In the quarter ended September 25, 2020, Cinos China amended its existing Credit Agreement and entered into two additional Credit Agreements with a local bank that provide Revolving Credit Facilities for a total available commitment of $3.5 million with various maturity dates through September 23, 2022 and interest rates ranging from 1.9% to 4.1%. As of September 25, 2020, Cinos China had an outstanding amount of $ 0.3 million with an interest rate of 1.9% under these Credit Agreements.

Cinos has Credit Agreements with various banks that provide Revolving Credit Facilities for a total available commitment of 1.6 billion Korean Won (approximately $1.4 million) with annual renewals beginning from April 2021 through June 2021 and interest rates ranging from 1.4% - 5.4%.  During the nine months ended September 25, 2020, borrowings under these Revolving Facilities were insignificant and no amounts were outstanding as of September 25, 2020.

As of September 25, 2020, our total bank debt was $280.1 million, net of unamortized debt issuance costs of $8.3 million. As of September 25, 2020, we had $55.0 million and $9.3 million available to borrow on our revolving credit facilities in the U.S. and Czech Republic, respectively.

The fair value of our long-term debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The carrying value of our long-term debt approximates fair value.

Capital Expenditures

Capital expenditures were $26.7 million during the nine months ended September 25, 2020 and were primarily attributable to the capital invested in our manufacturing facilities in the United States, China and South Korea as well as costs associated with the ongoing design and implementation of our new enterprise resource planning system. The Company’s anticipated capital expenditures for the remainder of 2020 are expected to be financed primarily from our cash flow generated from operations.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any relations with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Contractual Obligations

Other than operating leases for certain equipment, real estate and purchase order commitments, primarily for inventory, we have no off-balance sheet transactions, unconditional purchase obligations or similar instruments and, other than the arrangements described under “Borrowing Arrangements” above, are not a guarantor of any other entities’ debt or other financial obligations. The following table summarizes our future minimum lease payments, principal payments under debt obligations and our purchase obligations for the purchase of inventory as of September 25, 2020:

(In millions)	Total		Fiscal Year 2020		Fiscal Years 2021 - 2022		Fiscal Years 2023 - 2024		Beyond

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

There were no significant changes to our quantitative and qualitative disclosures about market risk during the period covered by this report. Refer to Part II, Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included in our Annual Report on Form 10-K for our fiscal year ended December 27, 2019 for a more complete discussion of the market risks we encounter.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Exchange Act. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our chief executive officer and our chief financial officer concluded that because of the material weaknesses identified in our internal control over financial reporting discussed below, our disclosure controls and procedures were not effective as of September 25, 2020, the end of the period covered by this Quarterly Report on Form 10-Q.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Previously Identified Material Weaknesses in Internal Control Over Financial Reporting

We previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 27, 2019, the following control deficiencies related to our Semiconductor Services Business (SSB) segment, which continue to exist as of September 25, 2020, that constitute material weaknesses in our internal control over financial reporting:

• In August 2018, we acquired Quantum Global Technologies, LLC, a privately held company (now reported as our SSB segment). During fiscal year 2019, management proceeded to implement control processes and procedures to integrate the acquired business into the overall Company. During fiscal 2019, process improvements were made; however, we determined that the control environment of SSB lacks the maturity and design effectiveness necessary to comply with the requirements of the Sarbanes-Oxley Act of 2002. As of December 27, 2019, management concluded that due to deficiencies in the design and implementation of business process controls and information technology general controls relating to all relevant accounts and cycles within SSB, material weaknesses exist.

Remediation Plan for Material Weaknesses

We are taking the steps necessary to remediate the control deficiencies that constituted the material weaknesses described above by implementing changes to our internal control over financial reporting. Management is implementing measures to ensure that the control deficiencies contributing to the material weaknesses are remediated, and that these controls are designed and operating effectively. We are using both internal and external resources to assist in the following actions:

• Assess key business cycles at material SSB locations to ensure that the processes, procedures and controls are adequately designed, clearly documented, standardized, appropriately communicated and executed timely to enhance control ownership throughout SSB.

• Strengthen the information technology general controls that support SSB’s critical process areas.

• Enhance SSB’s monitoring procedures by implementing new training activities and hiring additional qualified personnel.

• Ensure appropriate resources and controls are fully incorporated into the corporate oversight function.

- 33 -

Status of Remediation Efforts

As described below, we are in the midst of our remediation process, and have taken the following steps to remediate the control deficiencies that constituted the material weaknesses described above:

• We have completed the closure of the SSB Quakertown site, and consolidated the SSB finance team into our Hayward and Singapore sites. We have hired additional qualified accounting personnel to support the remediation effort and will continue to hire qualified accounting personnel as necessary, and have initiated employee training that will be ongoing.

• In addition, we have added key controls at the corporate level to ensure oversight of SSB accounting close functions including, ensuring journal entries recorded and general ledger account reconciliations have evidence of review and approval.

• We have begun the ERP implementation project to transition SSB’s legacy ERP system to SAP.

• We are in the process of designing, documenting and implementing new controls at significant SSB locations. Management will test these controls to ensure they have operated effectively for a sufficient period of time before concluding on remediation.

• We have implemented and are in the process of implementing controls surrounding user access and program change management over certain information technology systems that support the company’s financial reporting process.

We believe the measures described above will facilitate the remediation of the control deficiencies we have identified and strengthen our internal control over financial reporting. We are committed to continuing to improve our internal control processes and will continue to review, optimize and enhance our financial reporting controls and procedures. As we continue to evaluate and work to improve our internal control over financial reporting, we may take additional measures to address control deficiencies, or we may modify, or, in appropriate circumstances, not complete, certain of the remediation measures described above. These material weaknesses will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control Over Financial Reporting

Except for the remediation efforts discussed above under “Status of Remediation Efforts”, there were no changes in internal controls over financial reporting during the fiscal third quarter ended September 25, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we are subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims cannot be predicted with certainty, we have not had a history of outcomes to date that have been material to our Condensed Consolidated Statement of Operations and do not believe that any of these proceedings or other claims will have a material adverse effect on our condensed consolidated financial condition or results of operations.

ITEM 1A. Risk Factors

There were no material changes during the period covered in this report to the risk factors previously disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 27, 2019, except as follows:

COVID-19 pandemic

The COVID-19 outbreak is now a global pandemic as declared by the World Health Organization in March 2020. In response to the rapidly spreading pandemic, many governments around the world, including those in the United States, have taken the unprecedented measures to slow the spread, including the implementation of various forms of “shelter-in-place” orders that shut down most business operations around the globe. UCT’s work in manufacturing and cleaning semiconductor equipment parts is considered “essential critical infrastructure” work as identified in the federal guidelines issued by the U.S. Department of Homeland Security, which deemed semiconductor supply chain vendors critical to the continuity of economic and national security. To date, we have continued our operations within the permitted boundaries set forth in both the federal guidelines and state and local shelter-in-place orders. The future impact of COVID-19 on our business, however, is extremely difficult to estimate, as much of it depends on the efficacy of the current shelter-in-place orders in slowing down the pandemic, the governments’ changing calculations on the economic impact and the health implications of maintaining these orders, the progress in the healthcare industry’s ability to effectively combat the virus, and potential increase or decrease in semiconductor demand resulting from COVID-19 responses, all of which are highly unpredictable. Likewise, the financial market as a whole has experienced extreme volatility as a result of the global economic impact of the COVID-19 pandemic, which has impacted, and may continue to impact, our stock price.   

Cybersecurity

Cybersecurity attacks are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data, and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data (our own or that of third parties). Although we have adopted certain measures to mitigate potential risks to our systems from information technology-related disruptions, given the unpredictability of the timing, nature and scope of such disruptions, we could potentially be subject to production downtimes, operational delays, other detrimental impacts on our operations or ability to provide products and services to our customers, the compromising of confidential or otherwise protected information, misappropriation, destruction or corruption of data, security breaches, other manipulation or improper use of our systems or networks, financial losses from remedial actions, loss of business or potential liability, and/or damage to our reputation, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In August 2020, a third party gained unauthorized access to some of our data by launching a cyberattack on some of our servers. The Company believes that information related to fewer than 6000 employees (and former employees) of the Company was accessed, and that the information included social security numbers and some financial and credit card account numbers. While remedial actions are ongoing, including notifying all affected individuals and relevant state regulatory agencies, the attack has had no impact on our operations, and we do not anticipate that it will have any material adverse effect on our business, financial condition, results of operations or cash flows.

The Company’s products include chemical delivery modules, frame assemblies, gas delivery systems, fluid delivery systems, precision robotics, process modules as well as other high-level assemblies. The Company’s services provide part cleaning, surface encapsulation, and high sensitivity micro contamination analysis primarily for the semiconductor device makers and wafer fabrication equipment markets.

The Company reports results for two segments: Semiconductor Products and Solutions (“Products” or “SPS”) and Semiconductor Services Business (“Services” or “SSB”).

Basis of Presentation — The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary for the fair financial statement presentation for the dates and periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted. The Company’s December 27, 2019 balance sheet data were derived from its audited financial statements as of that date.

Fiscal Year — The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.

Principles of Consolidation — The Company’s Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries with the ownership interests of minority shareholders presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated upon consolidation.

Noncontrolling interests — The Company recognizes noncontrolling interests to reflect the portion of the equity of the majority-owned subsidiaries which is not attributable, directly or indirectly, to the controlling stockholder. The Company’s consolidated entities include partially-owned entities, which are (1) Cinos Co., Ltd (“Cinos Korea”), a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea, 86.0% of whose equity interests the Company is obligated to purchase and whose results the Company consolidates and (2) Cinos Xian Clean Technology, Ltd. (“Cinos China”), a Chinese entity that is 60.0% owned by Cinos Korea. The interest held by others in Cinos Korea and in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The noncontrolling interests will continue to be attributed their share of gains and losses even if that attribution results in a deficit noncontrolling interests balance.

Segments — The Financial Accounting Standards Board’s (“FASB”) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is the Chief Executive Officer. The Company operates and reports two segments. See Note 15 to the Company’s Consolidated Financial Statements.

Foreign Currency Translation and Remeasurement — The functional currency of the SPS business unit’s foreign subsidiaries is the U.S. dollar. The functional currency of the SSB business unit’s foreign subsidiaries is the local currency except for that of its Singapore and Scotland entities, which is the U.S. dollar.

The functional currency of the Company’s other international subsidiaries is either the U.S. dollar or their local currency. For the Company’s foreign subsidiaries where the local currency is the functional currency, the Company translates the financial statements of these subsidiaries to U.S. dollars using month-end exchange rates for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in AOCI as a component of stockholders' equity. For the Company’s foreign subsidiaries where the U.S. dollar is the functional currency, any gains and losses resulting from the translation of the assets and liabilities of these subsidiaries are recorded in other income (expense), net.

Use of Estimates — The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include inventory valuation, accounting for income taxes, business combinations, valuation of goodwill, intangible assets and long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments routinely require adjustments. Actual amounts may differ from those estimates.

Cash and Cash Equivalents — The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally.

Concentration of Credit Risk — Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company sells its products and provides services primarily to semiconductor capital equipment manufacturers in the United States. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

Two of the Company’s customers accounted for 10% or more of revenues and their related revenues as a percentage of total revenues were as follows:  

	Three Months Ended						Nine Months Ended
	September 25,			September 27,			September 25,			September 27,
	2020			2019			2020			2019
Lam Research Corporation		42.9	%		37.6	%		42.3	%		39.4	%
Applied Materials, Inc.		25.2	%		24.3	%		25.0	%		21.5	%
Total		68.1	%		61.9	%		67.3	%		60.9	%

In addition, three of the Company’s customers: Lam Research Corporation, Applied Materials, Inc. and ASM International, Inc., had accounts receivable balances that were individually greater than 10% of total accounts receivable as of September 25, 2020 and December 27, 2019, and in the aggregate approximately 59.1% and 66.7% of total accounts receivable, respectively.

Fair Value of Measurements — The Company measures its cash equivalents, contingent earn-out liabilities, pension obligation and common stock purchase obligation at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.

Level 3 — Unobservable inputs that are supported by little or no market activities.

Inventories — Inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of the Company’s products.

Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.

Property, Plant and Equipment, net — Property, plant and equipment are stated at cost, or, in the case of equipment under finance leases, the present value of future minimum lease payments at inception of the related lease. The Company also capitalizes interest on borrowings related to eligible capital expenditures. Capitalized interest is added to the cost of the qualified assets and depreciated. Depreciation and amortization are computed using the straight-line method over the lesser of the estimated useful lives of the assets or the terms of the leases. Useful lives range from three to fifty years. Direct costs incurred to develop software for internal use are capitalized and amortized over an estimated useful life of three or ten years. Costs related to the design or maintenance of internal use software are expensed as incurred. Capitalized internal use software is included in computer equipment and software.

Long-lived Assets — The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The Company assesses the fair value of the assets based on the amount of the undiscounted future cash flows that the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than the carrying value of the asset. If the Company identifies an impairment, the Company reduces the carrying value of the group of assets to comparable market values, when available and appropriate, or to its estimated fair value based on a discounted cash flow approach.

The Company assessed the useful lives of its long-lived assets, including property, plant and equipment as well as its intangible assets as of September 25, 2020 and concluded that no impairment was required.

Leases — The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement. When the Company determines the arrangement is a lease, or contains a lease, at lease inception, it then determines whether the lease is an operating lease or a finance lease. Operating and finance leases with lease terms of one year or greater result in the Company recording a right-of-use (ROU) asset and lease liability on its balance sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are initially recognized based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable or when the implicit interest rate is not readily determinable, the Company uses its incremental borrowing rate. The incremental borrowing rate is not a commonly quoted rate and is derived through a combination of inputs including the Company’s credit rating and the impact of full collateralization. The incremental borrowing rate is based on the Company’s collateralized borrowing capabilities over a similar term of the lease payments. The Company utilizes the consolidated group incremental borrowing rate for all leases. The operating lease ROU asset also includes any lease payments made and excludes any lease incentives. Specific lease terms used in computing the ROU assets and lease liabilities may include options to extend or terminate the lease when the Company believes it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. As allowed by the guidance, the Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, other current liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheet. The Company’s finance leases at September 25, 2020 and December 27, 2019 were not significant.

Goodwill and Indefinite Lived Intangible Assets — Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. Intangible assets are presented at cost, net of accumulated amortization, and are amortized on either a straight-line method or on an accelerated method over their estimated future discounted cash flows. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.

Deferred Debt Issuance Costs — Debt issuance costs incurred in connection with obtaining debt financing are deferred and presented as a direct deduction from Bank Borrowings in the accompanying Condensed Consolidated Balance Sheets. Costs incurred in connection with revolving credit facilities and letter of credit facilities are deferred and presented as an offset to bank borrowings in the accompanying Condensed Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.

Defined Benefit Pension Plan — The Company has a noncontributory defined benefit pension plan covering substantially all of the employees of one of its foreign entities upon termination of their employee services. For further discussion of the Company’s defined benefit pension plan see Note 8 of Notes to the Condensed Consolidated Financial Statements.

Revenue Recognition — Revenue is recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company assesses collectability based on the credit worthiness of the customer and past transaction history. The Company performs on-going credit evaluations of customers and generally does not require collateral from customers.

Shipping and Handling Costs — Shipping and handling costs are included as a component of cost of revenues.

Research and Development Costs — Research and development costs are expensed as incurred.

Stock-Based Compensation Expense — The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives and certain employees. These equity-based awards include stock options, restricted stock awards and restricted stock units. The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price.

Government Subsidies — Government subsidies are recognized where there is reasonable assurance that the subsidy will be received and all attached conditions will be complied with. When the subsidy relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the subsidy relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. When the subsidy does not relate to specific expenses or assets, the income is accounted for in the period where there is reasonable assurance that the subsidy will be received.

Income Taxes — The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future state, federal, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. The Company continued to maintain a full valuation allowance on its federal and state deferred tax amounts as of September 25, 2020.

Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the Condensed Consolidated Statements of Operations as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a significant impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty.

Net Income per Share — Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive stock options and restricted stock using the treasury stock method, except when such shares are anti-dilutive. See Note 14 to the Company’s Condensed Consolidated Financial Statements.

Business Combinations — The Company recognizes assets acquired (including goodwill and identifiable intangible assets), liabilities assumed and noncontrolling interest at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.

Accounting Standard Not Yet Adopted

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis

through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of this new standard on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financing Reporting. This guidance provides temporary optional expedients and exceptions through December 31, 2022 to the U.S. GAAP guidance on contract modifications to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance was effective upon issuance. As a result, the Company adopted the guidance in the second quarter of fiscal 2020 and there was no financial impact on the Condensed Consolidated Financial Statements upon adoption.

2. BUSINESS COMBINATIONS

Dynamic Manufacturing Solutions, LLC (“DMS”)

On April 15, 2019, the Company purchased substantially all of the assets of DMS, a semiconductor weldment and solutions provider. Pursuant to the purchase agreement, the former owners of DMS were entitled to up to a maximum of $12.5 million of potential cash earn-out if the combined weldment business achieves certain gross profit and gross margin targets for the twelve months ended June 26, 2020. The fair value of the earn-out at the acquisition date was $1.5 million and was determined using a risk-adjusted earnings projection utilizing the Monte Carlo Simulation method. These inputs are not observable in the market and thus represent a Level 3 measurement as discussed in Note 1 of the Company’s Condensed Consolidated Financial Statements. The total purchase consideration of DMS for purposes of the Company’s purchase price allocation was determined to be $31.4 million, which includes the cash payment of $29.9 million and the fair value of the potential earn-out payments of $1.5 million.

During the second quarter of fiscal year 2020, DMS achieved the specified performance target of the earn-out, which resulted in the maximum payout of $12.5 million, which was paid in August 2020. The increase in fair value of $3.0 from $9.5 million at December 27, 2019 was recorded as other expense in the condensed consolidated statement of operations for the nine months ended September 25, 2020, respectively.

In the first quarter of fiscal year 2020, the Company completed the acquisition accounting and the valuation of the fair value of the assets acquired and the liabilities assumed. The following table summarizes the recognized amounts of assets acquired and liabilities assumed at the acquisition date:

Fair Market Values (in millions)
Accounts receivable	$	1.5
Inventories		8.9
Equipment and leasehold improvements		5.4
Goodwill		12.3
Purchased intangible assets		6.9
Other non-current assets		0.3
Total assets acquired		35.3
Accounts payable		(3.8	)

Purchase consideration transferred	$	31.4

			Purchased
	Useful Life		Intangible Assets
	(In years)		(In millions)
Customer relationships		6	$	6.9

The results of operations for the three and nine months ended September 27, 2019 included operating activity for DMS since its acquisition date of April 15, 2019. The results of operations for the three and nine months ended September 25, 2020, included charges attributable to amortization of purchased intangible assets of $0.3 million and $0.9 million, respectively, and $0.3 million and $0.5 million for the three and nine months ended September 27, 2019, respectively, which are included in general and administrative expenses in the Condensed Consolidated Statements of Operations.

4. FAIR VALUE MEASUREMENTS

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following table summarizes, for assets or liabilities measured at fair value, the respective fair value and the classification by level of input within the fair value hierarchy:

			Fair Value Measurement at

Goodwill And Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

5. GOODWILL AND INTANGIBLE ASSETS

The Company’s methodology for allocating the purchase price relating to an acquisition is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the consideration transferred over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed.

To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company concludes it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, the Company does not proceed to perform a quantitative impairment test. If the Company concludes it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative goodwill impairment test will be performed by comparing the fair value of each reporting unit to its carrying value. A quantitative impairment analysis, if necessary, considers the income approach, which requires estimates of the present value of expected future cash flows to determine a reporting unit’s fair value. Significant estimates include revenue growth rates and operating margins used to calculate projected future cash flows, discount rates, and future economic and market conditions. A goodwill impairment charge is recognized for the amount by which the reporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The process of evaluating the potential impairment of goodwill and intangible assets requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends and lower projections of profitability that may impact future operating results.

Details of aggregate goodwill of the Company are as follows:

(In millions)	SPS		SSB		Total
Balance at December 27, 2019	$	97.6	$	73.5	$	171.1
Adjustments	—		—		—
Balance at September 25, 2020	$	97.6	$	73.5	$	171.1

Intangible Assets

Intangible assets are generally recorded in connection with a business acquisition. The Company evaluates the useful lives of its intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization. In addition, the Company reviews indefinite lived intangible assets for impairment when events or changes in circumstances indicate their carrying value may not be recoverable and tests definite lived intangible assets at least annually for impairment. Management considers such indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure.

Details of intangible assets were as follows:

		As of September 25, 2020							As of December 27, 2019
		Gross							Gross
	Useful Life	Carrying		Accumulated			Carrying		Carrying		Accumulated			Carrying
(Dollars in millions)	(in years)	Amount		Amortization			Value		Amount		Amortization			Value
Customer relationships	6 - 10	$	119.4	$	(47.9	)	$	71.5	$	119.4	$	(39.8	)	$	79.6
Tradename	4 - 6*		27.0		(10.8	)		16.2		27.0		(8.1	)		18.9
Intellectual property/know-how	7 - 12		13.9		(9.4	)		4.5		13.9		(8.4	)		5.5

Total		$	242.1	$	(76.6	)	$	165.5	$	242.1	$	(61.8	)	$	180.3

* The Company concluded that the UCT tradename intangible asset amounting to $9.0 million has an indefinite life and is therefore not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

The Company amortizes its intangible assets on a straight-line or accelerated basis over the estimated economic life of the assets. Amortization expense was approximately $4.9 million and $5.1 million for the three months ended September 25, 2020 and September 27, 2019, respectively, and was approximately $14.8 million and $15.0 million for the nine months ended September 25, 2020 and September 27, 2019. Amortization expense related to QGT’s recipes and standard operating procedures is charged to cost of revenues and the remainder is charged to general and administrative expense. As of September 25, 2020, future estimated amortization expense is expected to be as follows:

Borrowing Arrangements

6. BORROWING ARRANGEMENTS

In August 2018, the Company entered into a credit agreement with Barclays Bank that provided a Term Loan, a Revolving Credit Facility, and a Letter of Credit Facility (the “Credit Facilities”). UCT and certain of its subsidiaries have agreed to secure all of their obligations under the Credit Facilities by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations). In August 2018, the Company borrowed $350.0 million under the Term Loan and used the proceeds, together with cash on hand, to finance the acquisition of QGT and to refinance its previous credit facilities.

The Term Loan has a maturity date of August 27, 2025, with monthly interest payments in arrears, quarterly principal payments of 0.625% of the original outstanding principal balance payable beginning January 2019, with the remaining principal paid upon maturity. The Term Loan accrues interest at a rate equal to a base LIBOR rate determined by reference to the London interbank offered rate for dollars, plus 4.5% (subject to certain adjustments quarterly based upon the Company’s consolidated leverage ratio).  At September 25, 2020, the Company had an outstanding amount under the Term Loan of $287.8 million, gross of unamortized debt issuance costs of $8.3 million.

The Revolving Credit Facility has an initial available commitment of $65.0 million and a maturity date of August 27, 2023. The Company pays a quarterly commitment fee in arrears equal to 0.25% of the average daily available commitment outstanding. In March 2020, the Company drew $40.0 million under the Revolving Credit Facility to fund operations. In September 2020, the revolver balance of $40.0 million was repaid in full.

As of September 25, 2020, the interest rate on the outstanding Term Loan was 4.7%. After December 31, 2021, LIBOR will officially be phased out. The Company will work with its bank to determine alternative risk-free rates.

The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of at least 1.25 to 1.00, and a consolidated leverage ratio (as defined in the New Credit Agreement) as of the last day of any fiscal quarter of no greater than 3.75 to 1.00. The Company was in compliance with all financial covenants as of the quarter ended September 25, 2020.

The Letter of Credit Facility has an initial available commitment of $50.0 million and a maturity date of August 27, 2023. The Company pays quarterly in arrears a fee equal to 2.5% (subject to certain adjustments as per the Term Loans) of the dollar equivalent of all outstanding letters of credit, and a fronting fee equal to 0.125% of the undrawn and unexpired amount of each letter of credit. As of September 25, 2020, the Company had $2.4 million of outstanding letters of credit with beneficiaries such as landlords of certain facility leases and government agencies making up the majority of the outstanding balance. The remaining available commitments are $47.6 million on the Letter of Credit Facility and $65.0 million on the Revolving Credit Facility.

The Company’s subsidiary in the Czech Republic, UCT Fluid Delivery Solutions s.r.o., (FDS) has a revolving credit facility which renews annually at the end of the fiscal second quarter. As of September 25, 2020, FDS had an outstanding amount of $0.3 million with an interest rate of 0.8% under the revolving credit facility.

In the quarter ended September 25, 2020, Cinos China amended its existing Credit Agreement and entered into two additional Credit Agreements with a local bank that provide Revolving Credit Facilities for a total available commitment of $3.5 million with various

maturity dates through September 23, 2022 and interest rates ranging from 1.9% to 4.1%. As of September 25, 2020, Cinos China had an outstanding amount of $ 0.3 million with an interest rate of 1.9% under these Credit Agreements.

Cinos Korea has Credit Agreements with various banks that provide Revolving Credit Facilities for a total available commitment of 1.6 billion Korean Won (approximately $1.4 million) with annual renewals beginning from April 2021 through June 2021 and interest rates ranging from 1.4% - 5.4%.  During the nine months ended September 25, 2020, borrowings under these Revolving Facilities were insignificant and no amounts were outstanding as of September 25, 2020.

As of September 25, 2020, the Company’s total bank debt was $280.1 million, net of unamortized debt issuance costs of $8.3 million. As of September 25, 2020, the Company had $65.0 million and $9.3 million available to borrow on its revolving credit facilities in the U.S. and Czech Republic, respectively.

The fair value of the Company’s long term-debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The Company’s carrying value approximates fair value for the Company’s long-term debt.

Income Tax

7. INCOME TAX

The Company's effective tax rate was 16.0% and 81.4% for the three months ended September 25, 2020 and September 27, 2019, respectively, and 20.6% and 80.5% for the nine months ended September 25, 2020 and September 27, 2019, respectively. The Company’s income tax provision was $4.8 million and $3.9 million for the three months ended September 25, 2020 and September 27, 2019, respectively, and $15.0 million and $8.2 million for the nine months ended September 25, 2020 and September 27, 2019, respectively. The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results in jurisdictions which are taxed at different rates and the impact of losses in jurisdictions with full federal and state valuation allowances.  

Company management continuously evaluates the need for a valuation allowance and, as of September 25, 2020, concluded that a full valuation allowance on its federal and state deferred tax assets was still appropriate.

The Company provides for U.S. income taxes on the earnings of its foreign subsidiaries to the extent required by the Tax Cuts and Jobs Act (TCJA). However, the Company does not provide for withholding taxes on that portion of the undistributed earnings of its foreign subsidiaries that it intends to reinvest indefinitely outside the U.S. In prior years, the Company determined that a portion of the current year earnings of one of its China subsidiaries may be remitted in the future to one of its foreign subsidiaries outside of China and, accordingly, the Company provided for the related withholding taxes in its Condensed Consolidated Financial Statements. The Company remitted a portion of those earnings during 2019 and may remit the remainder of the earnings on which withholding taxes have already been accrued but does not currently expect to remit any other Chinese earnings. The Company has also historically remitted earnings from its Singapore subsidiary to the U.S. and may do so again in the future. However, the Company has not accrued for withholding taxes on Singapore earnings as the country does not impose a withholding tax. If the Company changes its intent to reinvest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed than the previous anticipated remaining unremitted foreign earnings, the Company could be required to accrue or pay foreign taxes on some or all of these undistributed earnings. As of September 25, 2020, the Company had undistributed earnings of foreign subsidiaries that are considered indefinitely invested outside of the U.S. of approximately $212.6 million. It is not practicable to determine the tax liability that might be incurred if these earnings were to be distributed.

As of September 25, 2020 and September 27, 2019, the Company’s gross liability for unrecognized tax benefits, excluding interest, was $1.0 million for both periods. Although it is possible that some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was enacted. The CARES Act includes changes to tax provisions that benefit business entities and makes certain technical corrections to the 2017 TCJA. Tax relief measures for businesses include modifications to limitations on the deductibility of net operating losses (NOLs) such as a five-year carryback of NOLs incurred in tax years beginning in 2018, 2019 or 2020, and removal of the 80% of taxable income limitation on NOL deductions for tax years beginning before January 1, 2021.  Other tax relief measures include modifications to the limitations on the deductibility of interest for tax years beginning in 2019 and 2020, acceleration of alternative minimum tax credit refunds, payroll tax relief, and a technical correction to the TCJA that would provide accelerated depreciation deductions for qualified improvement property. The CARES Act also provides other non-tax benefits to assist those impacted by the COVID-19 pandemic. The Company has evaluated the impact of the CARES Act and determined that there was no significant impact to the income tax provision for the three and nine months ended September 25, 2020.  The Company also does not expect the provisions of the CARES Act to result in a significant cash benefit.  However, the Company continues to monitor and evaluate the regulatory and interpretive guidance related to the CARES Act.

Retirement Plans

8. RETIREMENT PLANS

Defined Benefit Pension Plan

Cinos Korea has a noncontributory defined benefit pension plan covering substantially all of its employees upon their retirement. The benefits are based on expected years of service and average compensation. The net period costs are recognized as employees render the services necessary to earn the postretirement benefits.  The Company records annual amounts relating to the pension plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates.  The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current and expected rates of return and trends when it is appropriate to do so.  The effect of modifications to those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using the corridor method.  The Company believes that the assumptions utilized in recording its obligations under the plan are reasonable based on its experience and market conditions.  

As of September 25, 2020, the benefit obligation of the plan is $8.7 million and the fair value of the benefit plan assets, which are invested in several fixed deposit accounts with a bank is $5.1 million.  As of September 25, 2020, the unfunded balance of the plan of $3.6 million has been accrued for by the Company and is included in other long-term liabilities.  Amounts recognized in accumulated other comprehensive income as of September 25, 2020 is $0.5 million.  The contributions to the plan by the Company and its subsidiaries during the year ended September 25, 2020 was $1.4 million. The benefits expected to be paid from the pension plan in each year from 2020-2024 are $0.2 million, $1.1 million, $2.2 million, $0.9 million and $1.0 million, respectively.  The aggregate benefits expected to be paid in the five years from 2025-2029 are $4.6 million.

Employee Savings and Retirement Plan

The Company sponsors a 401(k) savings and retirement plan (the “401(k) Plan”) for all U.S. employees who meet certain eligibility requirements. Participants could elect to contribute to the 401(k) Plan, on a pre-tax basis, up to 25% of their salary to a maximum of $19,500. The Company may make matching contributions of up to 3% of employee contributions based upon eligibility. The Company made approximately $0.6 million and $1.9 million discretionary employer contributions to the 401(k) Plan in the three and nine months ended September 25, 2020, respectively, and $0.3 million and $0.9 million for the three and nine months ended September 27, 2019, respectively.

Noncontrolling Interests

QGT owns 51.0% of the outstanding shares of Cinos, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and through a 60.0% interest in Cinos China. QGT is obligated to purchase shares held by another shareholder of Cinos Korea representing a 35.0% interest. QGT accounted for this unconditional obligation as an assumed liability and derecognized any noncontrolling interest related to the 35.0%, which brings its controlling interest up to 86.0%.  

The carrying value of the remaining 14.0% interest held by another shareholder in Cinos Korea and the 40.0% interest in the Cinos joint venture are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The fair values of the noncontrolling interests were estimated based on the values of Cinos Korea and Cinos China on a 100.0% basis. The values were calculated based on the pro-rata portion of total forecasted QGT earnings before interest expense, taxes, depreciation and amortization ("EBITDA") contributed by each entity.

The Company is obligated to purchase shares owned by a Cinos Korea shareholder. A certain number of shares would be purchased at a fixed price per share, while the other remaining shares would be purchased based on the greater of the then fair value of the stock

and the fixed price per share (floor). The Company has a firm obligation to purchase the shares and a call option, while the other shareholder has a put option. As of September 25, 2020, the fair value of the obligation is $8.2 million which has been recorded as a non-current liability in the accompanying consolidated balance sheets and represents a Level 3 measurement as discussed in Note 4 of the Company’s Consolidated Financial Statements. The agreement with Cinos Korea allows for the common stock purchase obligation to become due in December 2022, and once completed, the Company will own 86.0% of Cinos Korea.

Employee Stock Plans

11. EMPLOYEE STOCK PLANS

The Company grants stock awards in the form of restricted stock units (RSUs) and performance stock units (PSUs) to its employees as part of the Company’s long term equity compensation plan. These stock awards are granted to employees with a unit purchase price of zero dollars and typically vest over three years, subject to the employee’s continued service with the Company and, in the case of PSUs, subject to achieving certain performance goals. The Company also grants common stock to its board members in the form of restricted share awards (RSAs), which vest on the earlier of 1) the next Annual Shareholder Meeting, or 2) 365 days from date of grant.

Stock-based compensation expense includes compensation costs related to estimated fair values of awards granted. The estimated fair value of the Company’s equity-based awards, net of expected forfeitures, is amortized on a straight-line basis over the awards’ vesting period and is adjusted for subsequent changes in estimated forfeitures related to all equity-based awards and performance as it relates to PSUs.

The following table shows the Company’s stock-based compensation expense included in the Condensed Consolidated Statements of Operations:

	Three Months Ended						Nine Months Ended
	September 25,			September 27,			September 25,			September 27,
(In millions)	2020			2019			2020			2019

Stock-based compensation expense, net of tax	$	2.8		$	0.6		$	7.6		$	1.8

(1) Stock-based compensation expense capitalized in inventory for the three and nine months ended September 25, 2020 and for the three and nine months ended September 27, 2019 was not significant.

For purposes of determining compensation expense related to these RSUs, the fair value is determined based on the closing market price of the Company’s common stock on the date of award.

There were 21.2 thousand RSUs granted during the quarter ended September 25, 2020, with a weighted average fair value of $22.39 per share. For the nine months ended September 25, 2020, 0.8 million RSUs were granted with a weighted average fair value of $18.32 per share.

For the nine months ended September 25, 2020, 0.1 million vested shares were withheld to satisfy withholding tax obligations, resulting in the net issuance of 0.6 million shares.

As of September 25, 2020, approximately $18.4 million of stock-based compensation cost, net of estimated forfeitures, related to RSUs and PSUs remains to be amortized over a weighted average period of 1.9 years. As of September 25, 2020, a total of 1.7 million RSUs and PSUs remain outstanding with an aggregate intrinsic value of $35.9 million and a weighted average remaining contractual term of 1.3 year.

As of September 25, 2020, a total of 44,107 shares of RSAs were outstanding. The total unamortized expense of the Company’s unvested restricted stock awards as of September 25, 2020 was $0.6 million.

The following table summarizes the Company’s combined RSU, PSU and RSA activity for the nine months ended September 25, 2020:

Revenue From Contract With Customer [Abstract]

Revenue Recognition

12. REVENUE RECOGNITION

The Company sells its products and services primarily to customers in the semiconductor capital equipment industry. The Company’s revenues are highly concentrated, and we are therefore highly dependent upon a small number of customers. Typical payment terms with our customers range from thirty to sixty days.

The Company’s SPS segment provides warranty on its products for a period of up to two years and provides for warranty costs at the time of sale based on historical activity. Determination of the warranty reserve requires the Company to make estimates of product return rates and expected costs to repair or replace the products under warranty. If actual return rates and/or repair and replacement costs differ significantly from these estimates, adjustments to recognize additional cost of revenues may be required in future periods. The warranty reserve is included in other current liabilities on the Condensed Consolidated Balance Sheets and is not considered significant.

The Company’s products are manufactured at our facilities in the U.S.A., China, Singapore and the Czech Republic. The Company provides services from operations in the U.S.A., Singapore, United Kingdom, Israel, Taiwan, South Korea, and China. Sales to customers are initiated through a purchase order and are governed by our standard terms and conditions, written agreements, or both. Revenue is recognized when performance obligations under the terms of an agreement with a customer are satisfied; generally, this occurs with the transfer of control of the products or when the Company provides the services. Transfer of control occurs at a specific point-in-time. Based on the enforceable rights included in our agreements or prevailing terms and conditions, products produced by the Company without an alternative use are not protected by an enforceable right of payment that includes a reasonable profit throughout the duration of the agreement. Consignment sales are recognized in revenue at the earlier of the period that the goods are consumed or after a period of time subsequent to receipt by the customer as specified by terms of the agreement, provided control of the promised goods or services has transferred.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value-add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Certain of our customers may receive cash-based incentives, such as rebates or credits, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenues recognized. As of September 25, 2020, an accrual for unpaid customer rebates of $2.4 million was included in accrued expenses on the Company’s Consolidated Balance Sheet. The Company's disaggregated revenues are by segment.

The Company’s principal markets include America, Asia and Europe. The Company’s foreign operations are conducted primarily through its subsidiaries in China, Singapore, Israel, Taiwan, South Korea, the United Kingdom and the Czech Republic. Revenues by geographic area are categorized based on the customer’s location to which the products were shipped or services performed. The following table sets forth revenue by geographic area (in millions):

15. REPORTABLE SEGMENTS

The Company operates and reports results for two operating segments: SPS and SSB. These segments are organized primarily by the nature of the products and service they provide. The Company’s Chief Executive Officer (chief operating decision maker) views and evaluates operations based on the results of each of the reportable segments. The following table describes each segment:

Segment	Product or Services	Markets Served	Geographic Areas
SPS	Assembly Weldments Machining Fabrication	Semiconductor	United States Asia Europe
SSB	Cleaning Analytics	Semiconductor	United States Asia Europe

The Company uses segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. Segment profit or loss is defined as income or loss from continuing operations before other income and income taxes included in the accompanying condensed consolidated statements of operations.

Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented.

From April through September of the current year, the Singapore government announced a series of relief measures for wages paid to local employees with the purpose of supporting employers during this period of economic uncertainty related to the COVID-19 pandemic, including the co-funding of wages incurred by local employers for nine months ending December 31, 2020. The Company

estimated that the total amount of these subsidies will be $3.2 million of which $ 1.1 million and $1.8 million was recorded during the three and nine months ended September 25, 2020, respectively, as an offset to cost of revenues.

The Company also received unconditional subsidies of $0.6 million from the China government during the nine months ended September 25, 2020. These subsidies were recognized as other income in the condensed consolidated statements of operations. In addition, the China government reduced the cost of certain social insurance requirements and also subsidized rent which benefited the Company by $0.4 million and $1.1 million during the three and nine months ended September 25, 2020, respectively. These subsidies were recorded as an offset to cost of revenues and other operating expenses

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation — The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary for the fair financial statement presentation for the dates and periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted. The Company’s December 27, 2019 balance sheet data were derived from its audited financial statements as of that date.

Fiscal Year

Fiscal Year — The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.

Principles of Consolidation

Principles of Consolidation — The Company’s Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries with the ownership interests of minority shareholders presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated upon consolidation.

Noncontrolling interests

Noncontrolling interests — The Company recognizes noncontrolling interests to reflect the portion of the equity of the majority-owned subsidiaries which is not attributable, directly or indirectly, to the controlling stockholder. The Company’s consolidated entities include partially-owned entities, which are (1) Cinos Co., Ltd (“Cinos Korea”), a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea, 86.0% of whose equity interests the Company is obligated to purchase and whose results the Company consolidates and (2) Cinos Xian Clean Technology, Ltd. (“Cinos China”), a Chinese entity that is 60.0% owned by Cinos Korea. The interest held by others in Cinos Korea and in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The noncontrolling interests will continue to be attributed their share of gains and losses even if that attribution results in a deficit noncontrolling interests balance.

Segments

Segments — The Financial Accounting Standards Board’s (“FASB”) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is the Chief Executive Officer. The Company operates and reports two segments. See Note 15 to the Company’s Consolidated Financial Statements.

Foreign Currency Translation and Remeasurement

Foreign Currency Translation and Remeasurement — The functional currency of the SPS business unit’s foreign subsidiaries is the U.S. dollar. The functional currency of the SSB business unit’s foreign subsidiaries is the local currency except for that of its Singapore and Scotland entities, which is the U.S. dollar.

The functional currency of the Company’s other international subsidiaries is either the U.S. dollar or their local currency. For the Company’s foreign subsidiaries where the local currency is the functional currency, the Company translates the financial statements of these subsidiaries to U.S. dollars using month-end exchange rates for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in AOCI as a component of stockholders' equity. For the Company’s foreign subsidiaries where the U.S. dollar is the functional currency, any gains and losses resulting from the translation of the assets and liabilities of these subsidiaries are recorded in other income (expense), net.

Use of Estimates

Use of Estimates — The presentation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include inventory valuation, accounting for income taxes, business combinations, valuation of goodwill, intangible assets and long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments routinely require adjustments. Actual amounts may differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents — The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally.

Concentration of Credit Risk

Concentration of Credit Risk — Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company sells its products and provides services primarily to semiconductor capital equipment manufacturers in the United States. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

Two of the Company’s customers accounted for 10% or more of revenues and their related revenues as a percentage of total revenues were as follows:  

	Three Months Ended						Nine Months Ended
	September 25,			September 27,			September 25,			September 27,
	2020			2019			2020			2019
Lam Research Corporation		42.9	%		37.6	%		42.3	%		39.4	%
Applied Materials, Inc.		25.2	%		24.3	%		25.0	%		21.5	%
Total		68.1	%		61.9	%		67.3	%		60.9	%

In addition, three of the Company’s customers: Lam Research Corporation, Applied Materials, Inc. and ASM International, Inc., had accounts receivable balances that were individually greater than 10% of total accounts receivable as of September 25, 2020 and December 27, 2019, and in the aggregate approximately 59.1% and 66.7% of total accounts receivable, respectively.

Fair Value of Measurements

Fair Value of Measurements — The Company measures its cash equivalents, contingent earn-out liabilities, pension obligation and common stock purchase obligation at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.

Level 3 — Unobservable inputs that are supported by little or no market activities.

Inventories

Inventories — Inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of the Company’s products.

Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.

Property, Plant and Equipment, net

Property, Plant and Equipment, net — Property, plant and equipment are stated at cost, or, in the case of equipment under finance leases, the present value of future minimum lease payments at inception of the related lease. The Company also capitalizes interest on borrowings related to eligible capital expenditures. Capitalized interest is added to the cost of the qualified assets and depreciated. Depreciation and amortization are computed using the straight-line method over the lesser of the estimated useful lives of the assets or the terms of the leases. Useful lives range from three to fifty years. Direct costs incurred to develop software for internal use are capitalized and amortized over an estimated useful life of three or ten years. Costs related to the design or maintenance of internal use software are expensed as incurred. Capitalized internal use software is included in computer equipment and software.

Long-lived Assets

Long-lived Assets — The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The Company assesses the fair value of the assets based on the amount of the undiscounted future cash flows that the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than the carrying value of the asset. If the Company identifies an impairment, the Company reduces the carrying value of the group of assets to comparable market values, when available and appropriate, or to its estimated fair value based on a discounted cash flow approach.

The Company assessed the useful lives of its long-lived assets, including property, plant and equipment as well as its intangible assets as of September 25, 2020 and concluded that no impairment was required.

Leases

Leases — The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement. When the Company determines the arrangement is a lease, or contains a lease, at lease inception, it then determines whether the lease is an operating lease or a finance lease. Operating and finance leases with lease terms of one year or greater result in the Company recording a right-of-use (ROU) asset and lease liability on its balance sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are initially recognized based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable or when the implicit interest rate is not readily determinable, the Company uses its incremental borrowing rate. The incremental borrowing rate is not a commonly quoted rate and is derived through a combination of inputs including the Company’s credit rating and the impact of full collateralization. The incremental borrowing rate is based on the Company’s collateralized borrowing capabilities over a similar term of the lease payments. The Company utilizes the consolidated group incremental borrowing rate for all leases. The operating lease ROU asset also includes any lease payments made and excludes any lease incentives. Specific lease terms used in computing the ROU assets and lease liabilities may include options to extend or terminate the lease when the Company believes it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. As allowed by the guidance, the Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, other current liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheet. The Company’s finance leases at September 25, 2020 and December 27, 2019 were not significant.

Goodwill and Indefinite Lived Intangible Assets

Goodwill and Indefinite Lived Intangible Assets — Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. Intangible assets are presented at cost, net of accumulated amortization, and are amortized on either a straight-line method or on an accelerated method over their estimated future discounted cash flows. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.

Deferred Debt Issuance Costs

Deferred Debt Issuance Costs — Debt issuance costs incurred in connection with obtaining debt financing are deferred and presented as a direct deduction from Bank Borrowings in the accompanying Condensed Consolidated Balance Sheets. Costs incurred in connection with revolving credit facilities and letter of credit facilities are deferred and presented as an offset to bank borrowings in the accompanying Condensed Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.

Defined Benefit Pension Plan

Defined Benefit Pension Plan — The Company has a noncontributory defined benefit pension plan covering substantially all of the employees of one of its foreign entities upon termination of their employee services. For further discussion of the Company’s defined benefit pension plan see Note 8 of Notes to the Condensed Consolidated Financial Statements.

Revenue Recognition

Revenue Recognition — Revenue is recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company assesses collectability based on the credit worthiness of the customer and past transaction history. The Company performs on-going credit evaluations of customers and generally does not require collateral from customers.

Shipping and Handling Costs — Shipping and handling costs are included as a component of cost of revenues.

Research and Development Costs

Research and Development Costs — Research and development costs are expensed as incurred.

Stock-Based Compensation Expense

Stock-Based Compensation Expense — The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives and certain employees. These equity-based awards include stock options, restricted stock awards and restricted stock units. The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price.

Government Grants

Government Subsidies — Government subsidies are recognized where there is reasonable assurance that the subsidy will be received and all attached conditions will be complied with. When the subsidy relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the subsidy relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. When the subsidy does not relate to specific expenses or assets, the income is accounted for in the period where there is reasonable assurance that the subsidy will be received.

Income Taxes

Income Taxes — The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future state, federal, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. The Company continued to maintain a full valuation allowance on its federal and state deferred tax amounts as of September 25, 2020.

Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the Condensed Consolidated Statements of Operations as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a significant impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty.

Net Income per Share

Net Income per Share — Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive stock options and restricted stock using the treasury stock method, except when such shares are anti-dilutive. See Note 14 to the Company’s Condensed Consolidated Financial Statements.

Business Combinations

Business Combinations — The Company recognizes assets acquired (including goodwill and identifiable intangible assets), liabilities assumed and noncontrolling interest at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.

Accounting Standard Not Yet Adopted

Accounting Standard Not Yet Adopted

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis

through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of this new standard on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financing Reporting. This guidance provides temporary optional expedients and exceptions through December 31, 2022 to the U.S. GAAP guidance on contract modifications to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance was effective upon issuance. As a result, the Company adopted the guidance in the second quarter of fiscal 2020 and there was no financial impact on the Condensed Consolidated Financial Statements upon adoption.
