Notes to Consolidated Financial Statements (Unaudited)

(dollar figures in tables in thousands, except per share amounts)

Note 1 – Basis of Presentation and Selected Significant Accounting Policies

Basis of Presentation

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). All intercompany balances and transactions have been eliminated upon consolidation. All dollar figures presented in tables in the notes to consolidated financial statements are in thousands, except per share amounts.

Year End

We use a 52- or 53-week fiscal year ending on the last Friday in December. The three months ended June 26, 2020 and June 28, 2019 were both 13 weeks. References to the second quarter of 2020 and 2019 refer to the three-month periods then ended. References to fiscal year 2020 refer to our fiscal year ending December 25, 2020.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods presented. We base our estimates and judgments on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from the estimates made by management. Significant estimates include the fair value of assets and liabilities acquired in acquisitions, estimated useful lives for long‑lived assets, allowance for doubtful accounts, inventory valuation, uncertain tax positions, fair value assigned to stock options granted, and impairment analysis for both definite‑lived intangible assets and goodwill.

Revenue Recognition

We recognize revenue when control of promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. This amount is recorded as net sales in our consolidated statements of operations.

Transaction price – In most of our contracts, prices are generally determined by a customer-issued purchase order and generally remain fixed over the duration of the contract. Certain contracts contain variable consideration, including early-payment discounts and rebates. When a contract includes variable consideration, we evaluate the estimate of the variable consideration to determine whether the estimate needs to be constrained; therefore, we include the variable consideration in the transaction price only to the extent that it is probable that a significant reversal will not occur. Variable consideration estimates are updated at each reporting date. Historically, we have not incurred significant costs to obtain a contract. All amounts billed to a customer relating to shipping and handling are classified as net sales, while all costs incurred by us for shipping and handling are classified as cost of sales.

Performance obligations – Substantially all of our performance obligations pertain to promised goods (“products”), which are primarily comprised of fluid delivery subsystems, weldments, and other components. Most of our contracts contain a single performance obligation and are generally completed within twelve months. Product sales are recognized at a point-in-time, generally upon delivery, as such term is defined within the contract, as that is when control of the promised good has transferred. Products are covered by a standard assurance warranty, generally extended for a period of one to two years depending on the customer, which promises that delivered products conform to contract specifications. As such, we account for such warranties under ASC 460, Guarantees, and not as a separate performance obligation.

Contract balances – Accounts receivable represents our unconditional right to receive consideration from our customers. Accounts receivable are carried at invoice price less an estimate for doubtful accounts and estimated payment discounts. Payment terms vary by customer but are generally due within 15‑60 days. Historically, we have not incurred significant payment issues with our customers. We had no significant contract assets or liabilities on our consolidated balance sheets in any of the periods presented.

Commitments and Contingencies

We are periodically involved in legal actions and claims that arise as a result of events that occur in the normal course of operations. The ultimate resolution of these actions is not expected to have a material effect on our financial position or results of operations. Subsequent to the end of the first quarter, but before the financial statements were issued, we reached a mutual settlement with the counterparty of a contract dispute and, accordingly, recorded a $1.4 million contract settlement loss to cost of sales, as the settlement provided evidence relating to a loss that existed at March 27, 2020.

Accounting Pronouncements Recently Adopted

In June 2016, the FASB issued ASU 2016‑13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.

In August 2018, the FASB issued ASU 2018‑15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350‑40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new guidance clarifies the accounting for implementation costs in cloud computing arrangements. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.

Total intangible assets	$	103,723	$	(51,696	)	$	—	$	52,027

Note 5 – Leases

Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. For purposes of calculating operating lease ROU assets and operating lease liabilities, we use the non-cancellable lease term plus options to extend that we are reasonably certain to take. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. Our leases generally do not provide an implicit rate. As such, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

We lease facilities under various non-cancellable operating leases expiring through 2025. In addition to base rental payments, we are generally responsible for our proportionate share of operating expenses, including facility maintenance, insurance, and property taxes. As these amounts are variable, they are not included in lease liabilities. As of June 26, 2020, we had no operating leases executed for which the rental period had not yet commenced.

The components of lease expense are as follows:

	Three Months Ended				Six Months Ended
	June 26, 2020		June 28, 2019		June 26, 2020		June 28, 2019
Operating lease cost	$	1,332	$	1,660	$	2,652	$	3,293

Supplemental cash flow information related to leases is as follows:

	Six Months Ended
	June 26, 2020		June 28, 2019
Cash paid for amounts included in the measurement of lease liabilities:
Operating cash flows from operating leases	$	2,678	$	2,492

Supplemental balance sheet information related to leases is as follows:

	June 26, 2020
Weighted-average remaining lease term of operating leases	2.7 years
Weighted-average discount rate of operating leases	4.5%

Total future minimum lease payments		13,260
Less imputed interest		(863	)
Total lease liabilities	$	12,397

Note 6 – Income Taxes

Coronavirus Aid, Relief, and Economic Security (“CARES”) Act

In response to the COVID‑19 pandemic, the CARES Act was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). Corporate taxpayers may carryback net operating losses (“NOLs”) originating in 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the existing limitation on taxable income of 80% by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019, or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income, plus business interest income, subject to the existing 30% limit under the 2017 Tax Act, for 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation.

With the enactment of the CARES Act, we expect to generate an additional income tax refund of approximately $0.7 million from our NOL carryback provision, resulting from the benefit from additional interest and depreciation deductions. Accordingly, we recognized a benefit of $0.2 million related to the CARES Act in our income tax provision for the first quarter of 2020.

Income tax information for the periods reported are as follows:

	Three Months Ended						Six Months Ended
	June 26, 2020			June 28, 2019			June 26, 2020			June 28, 2019
Income tax expense (benefit)	$	189		$	(93	)	$	(53	)	$	(1,466	)
Income before income taxes	$	7,000		$	243		$	10,157		$	388
Effective income tax rate		2.7	%		-38.3	%		-0.5	%		-377.8	%

Our effective tax rate for the three and six months ended June 26, 2020 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate, excess tax benefits from share-based compensation, and the impact of the CARES Act.

Our effective tax rate for the second quarter of 2019 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate and excess tax benefits from share-based compensation. Our effective tax rate for the six months ended June 28, 2019 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate, the release of certain tax reserves related to statute of limitation expirations and settlements, and excess tax benefits from share-based compensation.

The ending balance for the unrecognized tax benefits for uncertain tax positions was approximately $2.3 million at June 26, 2020. The related interest and penalties were zero and $0.4 million, respectively. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant.

As of June 26, 2020, we were not under examination by tax authorities.

Note 7 – Employee Benefit Programs

401(k) Plan

We sponsor a 401(k) plan available to employees of our U.S.‑based subsidiaries. Participants may make salary deferral contributions not to exceed 50% of a participant’s annual compensation or the maximum amount otherwise allowed by law. Eligible employees receive a discretionary matching contribution equal to 50% of a participant’s deferral, up to an annual maximum of 4% of a participant’s annual compensation. Matching contributions were $0.5 million and $0.4 million for the second quarter of 2020 and 2019, respectively, and $1.0 million and $0.8 million for the six months ended June 26, 2020 and June 28, 2019, respectively.

Note 8 – Long-Term Debt

Long‑term debt consists of the following:

	June 26, 2020			December 27, 2019
Term loan	$	157,500		$	161,875
Revolving credit facility		49,162			19,162
Total principal amount of long-term debt		206,662			181,037
Less unamortized debt issuance costs		(2,499	)		(2,983	)
Total long-term debt, net		204,163			178,054
Less current portion		(8,750	)		(8,750	)
Total long-term debt, less current portion, net	$	195,413		$	169,304

On February 15, 2018, we amended and restated our credit agreement, which replaced our existing credit facilities with a $175.0 million term loan and a $125.0 million revolving credit facility. The amendment reduced our borrowing rate, depending on our leverage ratio, and extended the maturity date. We incurred debt issuance costs of $2.1 million in connection with the amendment. The amendment did not meet the definition of an extinguishment and was accounted for as a debt modification.

Interest is charged at either the Base Rate or the Eurodollar rate (as such terms are defined in the credit agreement) at our option, plus an applicable margin. The Base Rate is equal to the higher of i) the Prime Rate, ii) the Federal Funds Rate plus 0.5%, or iii) the Eurodollar Rate plus 1.00%. The Eurodollar rate is equal to LIBOR. The applicable margin on Base Rate and Eurodollar Rate loans is 0.75‑1.50% and 1.75‑2.50% per annum, respectively, depending on our leverage ratio. We are also charged a commitment fee of 0.20%-0.35% on the unused portion of our revolving credit facility. Base Rate interest payments and commitment fees are due quarterly. Eurodollar interest payments are due on the last day of the applicable interest period. At June 26, 2020, the term loan and revolving credit facility bore interest at the Eurodollar rate option of 3.95% and 3.68%, respectively.

Term loan principal payments of $2.2 million are due on a quarterly basis. The term loan and revolving credit facility mature on February 15, 2023.

Note 9 – Share‑Based Compensation

The 2016 Omnibus Incentive Plan (the “2016 Plan”) provides for grants of share‑based awards to employees, directors, and consultants. Awards may be in the form of stock options (“options”), tandem and non‑tandem stock appreciation rights, restricted share awards or restricted share units (“RSUs”), performance awards, and other share‑based awards. Forfeited or expired awards are returned to the incentive plan pool for future grants. Awards generally vest over four years, 25% on the first anniversary of the date of grant and quarterly thereafter over the remaining 3 years. Upon vesting of RSUs, employees may elect to have shares withheld to cover statutory minimum withholding taxes. Shares withheld are not reflected as an issuance of ordinary shares within our consolidated statements of shareholders’ equity, as the shares were never issued, and the associated tax payments are reflected as financing activities within our consolidated statements of cash flows.

Share‑based compensation expense across all plans for options, RSUs, and employee share purchase rights was $2.1 million and $1.5 million for the second quarter of 2020 and 2019, respectively, and $5.0 million and $2.8 million for the six months ended June 26, 2020 and June 28, 2019, respectively.

Employee Share Purchase Plan

The 2017 Employee Stock Purchase Plan (the “2017 ESPP”) grants employees the ability to designate a portion of their base-pay to purchase ordinary shares at a price equal to 85% of the fair market value of our ordinary shares on the first or last day of each 6 month purchase period. Purchase periods begin on January 1 or July 1 and end on June 30 or December 31, or the next business day if such date is not a business day. Shares are purchased on the last day of the purchase period.

During the six months ended June 26, 2020, 16,520 ordinary shares were purchased by eligible employees under the 2017 ESPP. As of June 26, 2020, approximately 2.4 million ordinary shares remain available for purchase under the 2017 ESPP.

Note 10 – Segment Information

Our Chief Operating Decision Maker, the Chief Executive Officer, reviews our results of operations on a consolidated level and executive staff is structured by function rather than by product category. Therefore, we operate in one operating segment. Key resources, decisions, and assessment of performance are also analyzed on a company‑wide level.

Foreign operations are conducted primarily through our wholly owned subsidiaries in Singapore and Malaysia. Our principal markets include North America, Asia and, to a lesser degree, Europe. Sales by geographic area represent sales to unaffiliated customers.

All information on sales by geographic area is based upon the location to which the products were shipped. The following table sets forth sales by geographic area:

	Three Months Ended				Six Months Ended
	June 26, 2020		June 28, 2019		June 26, 2020		June 28, 2019
United States of America	$	117,692	$	76,899	$	238,533	$	153,532
Singapore		74,327		43,298		147,536		80,277
Europe		18,536		9,797		33,495		24,890
Other		11,009		9,201		22,028		18,327
Total net sales	$	221,564	$	139,195	$	441,592	$	277,026

Foreign long-lived assets, exclusive of deferred tax assets, were $29.0 million and $30.3 million at June 26, 2020 and December 27, 2019, respectively.

Note 11 – Earnings per Share

The following table sets forth the computation of basic and diluted earnings per share and a reconciliation of the numerator and denominator used in the calculation:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and related notes included elsewhere in this report. The following discussion contains forward‑looking statements based upon our current plans, expectations, and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward‑looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in “Risk Factors.”

Overview

We are a leader in the design, engineering and manufacturing of critical fluid delivery subsystems for semiconductor capital equipment. Our primary offerings include gas and chemical delivery subsystems, collectively known as fluid delivery subsystems, which are key elements of the process tools used in the manufacturing of semiconductor devices. Our gas delivery subsystems deliver, monitor and control precise quantities of the specialized gases used in semiconductor manufacturing processes such as etch and deposition. Our chemical delivery subsystems precisely blend and dispense the reactive liquid chemistries used in semiconductor manufacturing processes such as electroplating and cleaning. We also manufacture certain components such as weldments and precision machined components for use in fluid delivery systems for direct sales to our customers. This vertically integrated portion of our business is primarily focused on metal and plastic parts that are used in gas and chemical systems, respectively.

Fluid delivery subsystems ensure accurate measurement and uniform delivery of specialty gases and chemicals at critical steps in the semiconductor manufacturing process. Any malfunction or material degradation in fluid delivery reduces yields and increases the likelihood of manufacturing defects in these processes. Historically, semiconductor OEMs internally designed and manufactured the fluid delivery subsystems used in their process tools. Currently, most OEMs outsource the design, engineering, and manufacturing of their gas delivery subsystems to a few specialized suppliers, including us. Additionally, many OEMs are also increasingly outsourcing the design, engineering, and manufacturing of their chemical delivery subsystems due to the increased fluid expertise required to manufacture these subsystems. Outsourcing these subsystems has allowed OEMs to leverage the suppliers’ highly specialized engineering, design, and production skills while focusing their internal resources on their own value-added processes. We believe that this outsourcing trend has enabled OEMs to reduce their fixed costs and development time, as well as provided significant growth opportunities for specialized subsystems suppliers like us.

We have a global footprint with production facilities in Malaysia, Singapore, South Korea, California, Florida, Minnesota, Oregon, and Texas. Our two largest customers by revenue were Lam Research and Applied Materials for all periods presented.

The following summarizes key financial information for the periods indicated:

COVID-19 Pandemic and Market Conditions Update

The COVID‑19 pandemic and related economic repercussions have created, and are expected to continue to create, significant volatility, uncertainty, and turmoil in our industry. While we are currently not subject to any site-wide government shutdowns, “social distancing” guidelines are resulting, and will continue to result in, reduced factory capacity. In addition, an increase in direct costs within our factories associated with employee personal protective equipment (“PPE”), facility cleaning and layout changes, together with increases in logistics costs and employee labor costs, as well as other operating inefficiencies have resulted in, and may continue to result in, lower revenues and operating margins. The extent and duration of these impacts cannot be specifically quantified given the dynamic nature and breadth of the pandemic’s impact on our operations and that of our customers and suppliers.

13

In response to the COVID‑19 pandemic, we have instituted weekly Business Continuity Plan (“BCP”) meetings with executive management, including our CEO, to address new challenges to our current operating environment and review the effectiveness of our current BCP approach to managing our business. As necessary, our CEO communicates with our board of directors regarding our BCP to ensure all stakeholders remain informed of COVID‑19 challenges affecting our business and the measures taken to address them. We have implemented, at minimum, the following steps at our facilities in order to ensure the safety and welfare of our employees, customers, suppliers, and visitors to our operations: (1) PPE has been provided to all employees and temperature screening is performed on all personnel entering our facilities, (2) production work environments have been set up and altered to meet social distancing guidelines, (3) most of our non-direct line manufacturing employees are working remotely, (4) business travel has largely stopped, with exceptions requiring CEO staff member approval, (5) increased cleaning and sanitizing of our facilities, and (6) production shift schedule changes to reduce the number of employees per shift within each production facility.

Comparison of the Three and Six Months Ended June 26, 2020 and June 28, 2019

Net Sales

	Three Months Ended				Change					Six Months Ended				Change
	June 26, 2020		June 28, 2019		Amount		%			June 26, 2020		June 28, 2019		Amount		%
	(dollars in thousands)
Net sales	$	221,564	$	139,195	$	82,369		59.2	%	$	441,592	$	277,026	$	164,566		59.4	%

The increase in net sales from the three and six months ended June 28, 2019 to the three and six months ended June 26, 2020 was primarily due to increased demand from our customers as a result of growth in the global wafer fabrication equipment market as it comes out of the recent cyclical downturn, as well as share-gains at our largest customers. On a geographic basis, sales in the U.S. increased by $40.8 million and $85.0 million from the three and six months ended June 28, 2019, respectively, to $117.7 million and $238.5 million for the three and six months ended June 26, 2020, respectively. Foreign sales increased by $41.6 million and $79.6 million from the three and six months ended June 28, 2019, respectively, to $103.9 million and $203.1 million for the three and six months ended June 26, 2020, respectively.

Cost of Sales and Gross Profit

	Three Months Ended						Change					Six Months Ended						Change
	June 26, 2020			June 28, 2019			Amount		%			June 26, 2020			June 28, 2019			Amount		%
	(dollars in thousands)
Cost of sales	$	192,302		$	119,662		$	72,640		60.7	%	$	383,556		$	237,270		$	146,286		61.7	%
Gross profit	$	29,262		$	19,533		$	9,729		49.8	%	$	58,036		$	39,756		$	18,280		46.0	%
Gross margin		13.2	%		14.0	%			- 80 bps				13.1	%		14.4	%			- 130 bps

The increase in cost of sales and gross profit from the three and six months ended June 28, 2019 to the three and six months ended June 26, 2020 was primarily due to increased sales volume.

The decrease in our gross margin from the second quarter of 2019 to the second quarter of 2020 was primarily due to increased costs to operate our production facilities in response to the COVID‑19 pandemic (see “COVID‑19 Pandemic and Market Conditions Update” above for expanded commentary) and unfavorable product mix, partially offset by higher operating leverage as a result of increased factory utilization. As a result of governmental shelter-in-place orders instituted in March 2020, our facilities in California and Malaysia were shut down for durations ranging from approximately 1‑3 weeks near the end of the first quarter, which also impacted output early in the second quarter. Additionally, during the second quarter of 2020, we made the decision to close our Union City, California facility, resulting in inventory write-off and severance costs of $1.5 million. The impact of this event resulted in a 70 basis point reduction in our gross margin during the second quarter of 2020.

The decrease in our gross margin from the six months ended June 28, 2019 to the six months ended June 26, 2020 was primarily due to increased costs to operate our production facilities and lower factory utilization in response to the COVID‑19 pandemic (see “COVID‑19 Pandemic and Market Conditions Update” above for expanded commentary) and unfavorable product mix, partially offset by higher operating leverage as a result of increased factory utilization. As a result of governmental shelter-in-place orders instituted in March 2020, our facilities in California and Malaysia were shut down for durations ranging from approximately 1‑3 weeks near the end of the first quarter. Additionally, during the first quarter of 2020, we reached a mutual settlement with the counterparty of a contract dispute and, accordingly, recorded a $1.4 million contract settlement loss to cost of sales, and during the second quarter of 2020, we made the decision to shut down our Union City, California facility, resulting in inventory write-off and severance costs of $1.5 million. The impact of these events resulted in a 70 basis point reduction in our gross margin during the six months ended June 26, 2020.

Research and Development

	Three Months Ended				Change					Six Months Ended				Change
	June 26, 2020		June 28, 2019		Amount		%			June 26, 2020		June 28, 2019		Amount		%
	(dollars in thousands)
Research and development	$	3,509	$	2,634	$	875		33.2	%	$	6,831	$	5,025	$	1,806		35.9	%

The increase in research and development expenses from the second quarter of 2019 to the second quarter of 2020 was primarily due to $0.7 million in increased employee-related expense resulting from increased engineering headcount, of which approximately $0.4 million was due to a small engineering team assumed in connection with our purchase of developed technology assets in the second quarter of 2019.

The increase in research and development expenses from the six months ended June 28, 2019 to the six months ended June 26, 2020 was primarily due to $1.4 million in increased employee-related expense resulting from increased engineering headcount, of which approximately $0.8 million was due to a small engineering team assumed in connection with our purchase of developed technology assets in the second quarter of 2019.

Selling, General, and Administrative

	Three Months Ended				Change					Six Months Ended				Change
	June 26, 2020		June 28, 2019		Amount		%			June 26, 2020		June 28, 2019		Amount		%

Selling, general, and administrative	$	13,113	$	10,685	$	2,428		22.7	%	$	29,731	$	22,443	$	7,288		32.5	%

The increase in selling, general, and administrative expense from the second quarter of 2019 to the second quarter of 2020 was primarily due (i) $1.6 million in increased employee-related expense, of which $0.6 million was from increased share-based compensation expense, (ii) $0.5 million in increased legal and professional fees, and (iii) $0.3 million in increased occupancy costs.

The increase in selling, general, and administrative expense from the six months ended June 28, 2019 to the six months ended June 26, 2020 was primarily due (i) $1.8 million in executive transition costs associated with the transition of our former CEO to Executive Chairman, (ii) $4.2 million in increased employee-related expense, of which $2.0 million was from increased share-based compensation expense, (iii) $0.9 million in increased legal and professional fees, and (iv) $0.5 million in increased occupancy costs; partially offset by the release of a $0.7 million indemnification asset in the first quarter of 2019, which was recorded in connection with our acquisition of Cal‑Weld in 2017, that did not repeat in the first quarter of 2020.

Amortization of Intangible Assets

	Three Months Ended				Change					Six Months Ended				Change
	June 26, 2020		June 28, 2019		Amount		%			June 26, 2020		June 28, 2019		Amount		%
	(dollars in thousands)
Amortization of intangibles assets	$	3,336	$	3,202	$	134		4.2	%	$	6,670	$	6,339	$	331		5.2	%

The increase in amortization expense from the three and six months ended June 28, 2019 to the three and six months ended June 26, 2020 was primarily due to incremental amortization expense from purchased developed technology assets during the second quarter of 2019.

Interest Expense

	Three Months Ended				Change						Six Months Ended				Change
	June 26, 2020		June 28, 2019		Amount			%			June 26, 2020		June 28, 2019		Amount			%
	(dollars in thousands)
Interest expense	$	2,302	$	2,762	$	(460	)		-16.7	%	$	4,676	$	5,530	$	(854	)		-15.4	%

The decrease in interest expense from the second quarter of 2019 to the second quarter of 2020 was primarily due to a decrease in our weighted average interest rate, from 4.89% to 3.93%, partially offset by a $4.1 million increase in our average amount borrowed during the quarter.

The decrease in interest expense from the six months ended June 28, 2019 to the six months ended June 26, 2020 was primarily due to a decrease in our weighted average interest rate, from 4.83% to 4.17%, and a $9.7 million decrease in our average amount borrowed during the six months ended June 26, 2020.

Other Expense (Income), Net

	Three Months Ended				Change				Six Months Ended					Change
	June 26, 2020		June 28, 2019		Amount			%	June 26, 2020			June 28, 2019		Amount			%
	(dollars in thousands)
Other expense (income), net	$	2	$	7	$	(5	)	n/m	$	(29	)	$	31	$	(60	)	n/m

The change in other income, net was primarily due to exchange rate fluctuations on transactions denominated in the local currencies of our foreign operations, principally the Singapore dollar, Malaysian ringgit, British pound, euro, and South Korean won.

Income Tax Expense (Benefit)

	Three Months Ended					Change					Six Months Ended						Change
	June 26, 2020		June 28, 2019			Amount		%			June 26, 2020			June 28, 2019			Amount		%
	(dollars in thousands)
Income tax expense (benefit)	$	189	$	(93	)	$	282		-303.2	%	$	(53	)	$	(1,466	)	$	1,413		-96.4	%

The decrease in income tax benefit from the second quarter of 2019 to the second quarter of 2020 was primarily due to increased taxable income in the U.S. in 2020.

The decrease in income tax benefit from the six months ended June 28, 2019 to the six months ended June 26, 2020 was primarily due to a decrease in releases of certain tax reserves related to statute of limitation expirations or settlements in the first quarter of 2020 compared to the first quarter of 2019, as well as increased taxable income in the U.S. in 2020.

Non‑GAAP Results

Management uses non-GAAP metrics to evaluate our operating and financial results. We believe the presentation of non-GAAP results is useful to investors for analyzing business trends and comparing performance to prior periods, along with enhancing investors’ ability to view our results from management’s perspective. Non-GAAP net income is defined as: net income excluding (1) amortization of intangible assets, share-based compensation expense, and non-recurring expenses, including contract settlement losses; and (2) the tax impacts associated with our non-GAAP adjustments, as well as non-recurring discrete tax items. Non-GAAP diluted EPS is defined as non-GAAP net income divided by weighted average diluted ordinary shares outstanding during the period.

The following table presents our unaudited non‑GAAP net income and a reconciliation from net income, the most comparable GAAP measure, for the periods indicated:

	Three Months Ended						Six Months Ended
	June 26, 2020			June 28, 2019			June 26, 2020			June 28, 2019

Shares used to compute diluted EPS		23,066,976			22,663,053			23,099,946			22,596,412

(1) Included in this amount for the second quarter of 2020 and the six months ended June 26, 2020 are (i) a $1.8 million bonus payment to our former CEO in connection with his transition to executive chairman, (ii) acquisition-related expenses, comprised primarily of expense associated with a two-year retention agreement between the Company and key management personnel of IAN (the “IAN retention agreement”), which we acquired in April 2018, and (iii) non-capitalizable costs incurred in connection with our implementation of a new ERP system and a Sarbanes-Oxley (“SOX”) compliance program.

Included in this amount for the second quarter of 2019 are (i) acquisition-related expenses, comprised primarily of expense associated with a two-year retention agreement between the Company and key management personnel of IAN, which we acquired in April 2018 and (ii) costs associated with restructuring and transitioning key leadership roles.

Included in this amount for the six months ended June 28, 2019 are (i) acquisition-related expenses, comprised primarily of a charge to expense from the extinguishment of an indemnification asset related to our acquisition of Cal‑Weld in 2017 and expense associated with a two-year retention agreement between the Company and key management personnel of IAN, (ii) costs incurred in connection with reorganizing our key personnel and leadership, and (iii) costs incurred with implementing a new ERP system.

(2) During the first quarter of 2020, we reached a mutual settlement with the counterparty of a contract dispute and, accordingly, recorded a $1.4 million contract settlement loss to cost of sales.

(3) During the second quarter of 2020, we announced the closure of our manufacturing facility in Union City, California, which we expect to complete by the end of our 2020 fiscal year. Included in this amount are inventory write-off costs of $1.3 million and severance costs of $0.2 million associated with the affected employees.

(4) Adjusts U.S. GAAP income tax benefit for impact of our non-GAAP adjustments, as defined, including the impacts of excluding share-based compensation, amortization of intangible assets, and other non-recurring expenses. This adjustment also excludes the impact of non-recurring discrete tax items, including the release of tax reserves related to purchase accounting and the release or placement of a valuation allowance.

Non-GAAP results have limitations as an analytical tool, and you should not consider them in isolation or as a substitute for our results reported under GAAP. Other companies may calculate non-GAAP results differently or may use other measures to evaluate their performance, both of which could reduce the usefulness of our non-GAAP results as a tool for comparison.

18

Because of these limitations, you should consider non-GAAP results alongside other financial performance measures and results presented in accordance with GAAP. In addition, in evaluating non-GAAP results, you should be aware that in the future we will incur expenses such as those that are the subject of adjustments in deriving non-GAAP results and you should not infer from our presentation of non-GAAP results that our future results will not be affected by these expenses or any unusual or non-recurring items.

Liquidity and Capital Resources

We ended the second quarter of 2020 with cash of $57.0 million, a decrease of $3.6 million from December 27, 2019. The decrease was primarily due to cash used in operating activities of $25.2 million and capital expenditures of $5.7 million, partially offset by net proceeds from our credit facilities of $25.6 million and net proceeds from the issuance of shares under our share-based compensation plans of $1.6 million.

The various impacts of the COVID‑19 pandemic on the U.S. economy, our operations, and our industry have been significant. Nonetheless, at this time, we believe that our cash, the amounts available under our revolving credit facility, and our cash flows from operations will be sufficient to meet our anticipated cash needs for at least the next 12 months.

Cash Flow Analysis

	Six Months Ended
	June 26, 2020			June 28, 2019
	(in thousands)
Cash provided by (used in) operating activities	$	(25,183	)	$	20,660
Cash used in investing activities		(5,665	)		(14,264	)
Cash provided by (used in) financing activities		27,205			(8,774	)
Net decrease in cash	$	(3,643	)	$	(2,378	)

Operating Activities

Our cash used in operating activities of $25.2 million for the six months ended June 26, 2020 consists of net income of $10.2 million and net non-cash charges of $17.5 million, offset by an increase in our net operating assets and liabilities of $52.9 million. Net non-cash charges primarily consist of depreciation and amortization of $11.7 million and share-based compensation of $5.0 million. The increase in our net operating assets and liabilities was primarily due to an increase in inventories of $22.2 million, an increase in accounts receivable of $20.0 million, and a decrease of accounts payable of $13.7 million. The increase in inventories is primarily due to an increase in purchases to support increased volume, and the increase in accounts receivable is primarily due to increased sales volume during the quarter compared to the fourth quarter of 2019, as well as the timing of second quarter sales being heavily back-end weighted.

Investing Activities

Our cash used in investing activities of $5.7 million for the six months ended June 26, 2020 consists of capital expenditures.

Financing Activities

Our cash provided by financing of $27.2 million for the six months ended June 26, 2020 consists of net proceeds from our credit facilities of $25.6 million, partially offset by net proceeds from the issuance of ordinary shares under our share-based compensation plans of $1.6 million.

Critical Accounting Policies

Our consolidated financial statements have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, sales, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

The critical accounting policies requiring estimates, assumptions, and judgments that we believe have the most significant impact on our consolidated financial statements are identified and described in our annual consolidated financial statements and the notes included in our Annual Report on Form 10‑K for the year ended December 27, 2019 (our “Annual Report”).

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

Currently, substantially all of our sales and arrangements with third-party suppliers provide for pricing and payment in U.S. dollars and, therefore, are not subject to material exchange rate fluctuations. As a result, we do not expect foreign currency exchange rate fluctuations to have a material effect on our results of operations. However, increases in the value of the U.S. dollar relative to other currencies would make our products more expensive relative to competing products priced in such other currencies, which could negatively impact our ability to compete. Conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our foreign suppliers raising their prices in order to continue doing business with us.

While not currently significant, we do have certain operating expenses that are denominated in currencies of the countries in which our operations are located, and may be subject to fluctuations due to foreign currency exchange rates, particularly the Singapore dollar, Malaysian ringgit, British pound, euro, and South Korean won. Fluctuations in foreign currency exchange rates may cause us to recognize transaction gains and losses in our statement of operations. To date, foreign currency transaction gains and losses have not been material to our financial statements, and we have not engaged in any foreign currency hedging transactions.

Interest Rate Risk

We had total indebtedness of $206.7 million as of June 26, 2020, exclusive of $2.5 million in debt issuance costs, of which $8.8 million was due within 12 months. The outstanding amount of debt included elsewhere in this report is net of debt issuance costs.

We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. We have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. The interest rate on our outstanding debt is based on LIBOR, the Prime Rate, or the Federal Funds Rate. A hypothetical 1% interest rate change on our outstanding debt would have resulted in a $0.5 million change to interest expense during the second quarter of 2020, or $2.1 million on an annualized basis.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a‑15(b) under the Exchange Act, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act) as of the end of the period covered by this report. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 26, 2020.

Changes in Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed by, or under the supervision of, a company’s principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate. If we cannot provide reliable financial information, our business, operating results, and share price could be negatively impacted. There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the six months ended June 26, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are currently not a party to any material pending or threatened litigation.

ITEM 1A. RISK FACTORS

This quarterly report should be read in conjunction with the risk factors included in our 2019 Annual Report and our Quarterly Report for the quarter ended March 27, 2020. The following risk factor supersedes and replaces the risk factors contained in our Quarterly Report on Form 10-Q for the quarter ended March 27, 2020 under the caption entitled, “The extent to which the coronavirus (COVID-19) pandemic and measures taken in response thereto impact our business, results of operations and financial condition will continue to depend on future developments, which are highly uncertain and difficult to predict.”

Our business has been adversely affected by the Novel Coronavirus pandemic (“COVID‑19”) and we continue to face risks related to COVID‑19 which could significantly disrupt our operations, customer demand, and our suppliers’ ability to support us, resulting in material adverse impacts to our business, financial condition, operating results, and cash flows.

We are closely monitoring the outbreak of respiratory illness caused by COVID‑19. The virus has spread to many countries and has been declared by the World Health Organization to be a pandemic, resulting in action from federal, state and local governments that has significantly affected virtually all facets of the U.S. and global economies. The U.S. government has implemented enhanced screenings, quarantine requirements, and travel restrictions in connection with the COVID‑19 outbreak.

Shelter-in-place orders and other measures, including work-from-home and social distancing policies implemented to protect employees, have resulted in reduced workforce availability at product manufacturing sites, construction delays, and reduced capacity at some of our vendors and suppliers. Restrictions on our access to or operation of manufacturing facilities or on our support operations or workforce, or similar limitations for our vendors and suppliers, can impact our ability to meet customer demand and could have a material adverse effect on our financial condition and results of operations, particularly if prolonged. Similarly, current and future restrictions or disruptions of transportation, such as reduced availability of air transport, port closures, and increased border controls or closures, can also impact our ability to meet demand and could materially adversely affect us. Our customers have experienced, and may continue to experience, disruptions in their operations and supply chains, which can result in delayed, reduced, or canceled orders, or collection risks, and which may adversely affect our results of operations.

Our business may be more adversely impacted by the effects of COVID‑19 in the future. We source materials from different parts of the world that have been affected by the virus which could have an adverse impact on our supply chain operations and ability to get materials needed to build our products. Additionally, the disruption to global markets that has occurred due to the epidemic has increased uncertainty for semi-conductor demand. It is likely that the current outbreak and continued spread of COVID‑19 will cause an economic slowdown, and it is possible that it could cause a global recession. There is a significant degree of uncertainty and lack of visibility as to the extent and duration of any such slowdown or recession. Given the significant economic uncertainty and volatility created by the pandemic, it is difficult to predict the nature and extent of impacts on demand for our products. These expectations are subject to change without warning and investors are cautioned not to place undue reliance on them.

The spread of COVID‑19 has caused us to modify our business practices (including employee travel, employee work locations, cancellation of physical participation in meetings, events and conferences, and social distancing measures), and we may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers, partners, vendors, and suppliers. Work-from-home and other measures introduce additional operational risks, including cybersecurity risks, and have affected the way we conduct our product development, validation, and qualification, customer support, and other activities, which could have an adverse effect on our operations. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus, and illness and workforce disruptions could lead to unavailability of key personnel and harm our ability to perform critical functions.

The extent of the impact of COVID‑19 on our operational and financial performance will depend on future developments, including, but not limited to, the duration and spread of the outbreak and related travel advisories and restrictions, all of which are highly uncertain and cannot be predicted. Government shutdown orders or a change to our business classification as an “essential business” may result in a closure of operations for an uncertain duration impacting our business results. Preventing the effects from and responding to this market disruption if any other public health threat, related or otherwise, may further increase costs of our business and may have a material adverse effect on our business, financial condition, and results of operations.

21

While we have taken steps to minimize the potential for COVID‑19 exposure in the workplace, the potential for a COVID‑19 outbreak within our facilities occurring and significantly disrupting operations remains possible. Increased infection rates in geographic locations in which we operate have the potential to result in disruptions to our operations at an increased rate than we currently experience.

There are no comparable recent events that provide guidance as to the effect the spread of COVID‑19 as a global pandemic may have, and, as a result, the ultimate impact of the pandemic is highly uncertain and subject to change. We do not yet know the full extent of the impacts on our business, our operations or the global economy as a whole. However, the effects could materially heighten many of our known risks described in the “Risk Factors” section of our 2019 Annual Report.

Basis of Presentation and Selected Significant Accounting Policies

Accounting Policies [Abstract]

Basis of Presentation and Selected Significant Accounting Policies

Note 1 – Basis of Presentation and Selected Significant Accounting Policies

Basis of Presentation

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). All intercompany balances and transactions have been eliminated upon consolidation. All dollar figures presented in tables in the notes to consolidated financial statements are in thousands, except per share amounts.

Year End

We use a 52- or 53-week fiscal year ending on the last Friday in December. The three months ended June 26, 2020 and June 28, 2019 were both 13 weeks. References to the second quarter of 2020 and 2019 refer to the three-month periods then ended. References to fiscal year 2020 refer to our fiscal year ending December 25, 2020.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods presented. We base our estimates and judgments on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from the estimates made by management. Significant estimates include the fair value of assets and liabilities acquired in acquisitions, estimated useful lives for long‑lived assets, allowance for doubtful accounts, inventory valuation, uncertain tax positions, fair value assigned to stock options granted, and impairment analysis for both definite‑lived intangible assets and goodwill.

Revenue Recognition

We recognize revenue when control of promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. This amount is recorded as net sales in our consolidated statements of operations.

Transaction price – In most of our contracts, prices are generally determined by a customer-issued purchase order and generally remain fixed over the duration of the contract. Certain contracts contain variable consideration, including early-payment discounts and rebates. When a contract includes variable consideration, we evaluate the estimate of the variable consideration to determine whether the estimate needs to be constrained; therefore, we include the variable consideration in the transaction price only to the extent that it is probable that a significant reversal will not occur. Variable consideration estimates are updated at each reporting date. Historically, we have not incurred significant costs to obtain a contract. All amounts billed to a customer relating to shipping and handling are classified as net sales, while all costs incurred by us for shipping and handling are classified as cost of sales.

Performance obligations – Substantially all of our performance obligations pertain to promised goods (“products”), which are primarily comprised of fluid delivery subsystems, weldments, and other components. Most of our contracts contain a single performance obligation and are generally completed within twelve months. Product sales are recognized at a point-in-time, generally upon delivery, as such term is defined within the contract, as that is when control of the promised good has transferred. Products are covered by a standard assurance warranty, generally extended for a period of one to two years depending on the customer, which promises that delivered products conform to contract specifications. As such, we account for such warranties under ASC 460, Guarantees, and not as a separate performance obligation.

Contract balances – Accounts receivable represents our unconditional right to receive consideration from our customers. Accounts receivable are carried at invoice price less an estimate for doubtful accounts and estimated payment discounts. Payment terms vary by customer but are generally due within 15‑60 days. Historically, we have not incurred significant payment issues with our customers. We had no significant contract assets or liabilities on our consolidated balance sheets in any of the periods presented.

Commitments and Contingencies

We are periodically involved in legal actions and claims that arise as a result of events that occur in the normal course of operations. The ultimate resolution of these actions is not expected to have a material effect on our financial position or results of operations. Subsequent to the end of the first quarter, but before the financial statements were issued, we reached a mutual settlement with the counterparty of a contract dispute and, accordingly, recorded a $1.4 million contract settlement loss to cost of sales, as the settlement provided evidence relating to a loss that existed at March 27, 2020.

Accounting Pronouncements Recently Adopted

In June 2016, the FASB issued ASU 2016‑13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.

In August 2018, the FASB issued ASU 2018‑15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350‑40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new guidance clarifies the accounting for implementation costs in cloud computing arrangements. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.

Leases [Abstract]

Leases

Note 5 – Leases

Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. For purposes of calculating operating lease ROU assets and operating lease liabilities, we use the non-cancellable lease term plus options to extend that we are reasonably certain to take. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. Our leases generally do not provide an implicit rate. As such, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

We lease facilities under various non-cancellable operating leases expiring through 2025. In addition to base rental payments, we are generally responsible for our proportionate share of operating expenses, including facility maintenance, insurance, and property taxes. As these amounts are variable, they are not included in lease liabilities. As of June 26, 2020, we had no operating leases executed for which the rental period had not yet commenced.

The components of lease expense are as follows:

	Three Months Ended				Six Months Ended
	June 26, 2020		June 28, 2019		June 26, 2020		June 28, 2019
Operating lease cost	$	1,332	$	1,660	$	2,652	$	3,293

Supplemental cash flow information related to leases is as follows:

Income Taxes

Note 6 – Income Taxes

Coronavirus Aid, Relief, and Economic Security (“CARES”) Act

In response to the COVID‑19 pandemic, the CARES Act was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). Corporate taxpayers may carryback net operating losses (“NOLs”) originating in 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the existing limitation on taxable income of 80% by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019, or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income, plus business interest income, subject to the existing 30% limit under the 2017 Tax Act, for 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation.

With the enactment of the CARES Act, we expect to generate an additional income tax refund of approximately $0.7 million from our NOL carryback provision, resulting from the benefit from additional interest and depreciation deductions. Accordingly, we recognized a benefit of $0.2 million related to the CARES Act in our income tax provision for the first quarter of 2020.

Income tax information for the periods reported are as follows:

	Three Months Ended						Six Months Ended
	June 26, 2020			June 28, 2019			June 26, 2020			June 28, 2019
Income tax expense (benefit)	$	189		$	(93	)	$	(53	)	$	(1,466	)
Income before income taxes	$	7,000		$	243		$	10,157		$	388
Effective income tax rate		2.7	%		-38.3	%		-0.5	%		-377.8	%

Our effective tax rate for the three and six months ended June 26, 2020 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate, excess tax benefits from share-based compensation, and the impact of the CARES Act.

Our effective tax rate for the second quarter of 2019 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate and excess tax benefits from share-based compensation. Our effective tax rate for the six months ended June 28, 2019 differs from the statutory rate due to taxes on foreign income that differ from the U.S. tax rate, the release of certain tax reserves related to statute of limitation expirations and settlements, and excess tax benefits from share-based compensation.

The ending balance for the unrecognized tax benefits for uncertain tax positions was approximately $2.3 million at June 26, 2020. The related interest and penalties were zero and $0.4 million, respectively. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant.

As of June 26, 2020, we were not under examination by tax authorities.

Eligible employees receive a discretionary matching contribution equal to 50% of a participant’s deferral, up to an annual maximum of 4% of a participant’s annual compensation. Matching contributions were $0.5 million and $0.4 million for the second quarter of 2020 and 2019, respectively, and $1.0 million and $0.8 million for the six months ended June 26, 2020 and June 28, 2019, respectively.

Note 8 – Long-Term Debt

Long‑term debt consists of the following:

	June 26, 2020			December 27, 2019
Term loan	$	157,500		$	161,875
Revolving credit facility		49,162			19,162

Less current portion		(8,750	)		(8,750	)
Total long-term debt, less current portion, net	$	195,413		$	169,304

On February 15, 2018, we amended and restated our credit agreement, which replaced our existing credit facilities with a $175.0 million term loan and a $125.0 million revolving credit facility. The amendment reduced our borrowing rate, depending on our leverage ratio, and extended the maturity date. We incurred debt issuance costs of $2.1 million in connection with the amendment. The amendment did not meet the definition of an extinguishment and was accounted for as a debt modification.

Interest is charged at either the Base Rate or the Eurodollar rate (as such terms are defined in the credit agreement) at our option, plus an applicable margin. The Base Rate is equal to the higher of i) the Prime Rate, ii) the Federal Funds Rate plus 0.5%, or iii) the Eurodollar Rate plus 1.00%. The Eurodollar rate is equal to LIBOR. The applicable margin on Base Rate and Eurodollar Rate loans is 0.75‑1.50% and 1.75‑2.50% per annum, respectively, depending on our leverage ratio. We are also charged a commitment fee of 0.20%-0.35% on the unused portion of our revolving credit facility. Base Rate interest payments and commitment fees are due quarterly. Eurodollar interest payments are due on the last day of the applicable interest period. At June 26, 2020, the term loan and revolving credit facility bore interest at the Eurodollar rate option of 3.95% and 3.68%, respectively.

Term loan principal payments of $2.2 million are due on a quarterly basis. The term loan and revolving credit facility mature on February 15, 2023.

Share-Based Compensation

Note 9 – Share‑Based Compensation

The 2016 Omnibus Incentive Plan (the “2016 Plan”) provides for grants of share‑based awards to employees, directors, and consultants. Awards may be in the form of stock options (“options”), tandem and non‑tandem stock appreciation rights, restricted share awards or restricted share units (“RSUs”), performance awards, and other share‑based awards. Forfeited or expired awards are returned to the incentive plan pool for future grants. Awards generally vest over four years, 25% on the first anniversary of the date of grant and quarterly thereafter over the remaining 3 years. Upon vesting of RSUs, employees may elect to have shares withheld to cover statutory minimum withholding taxes. Shares withheld are not reflected as an issuance of ordinary shares within our consolidated statements of shareholders’ equity, as the shares were never issued, and the associated tax payments are reflected as financing activities within our consolidated statements of cash flows.

Share‑based compensation expense across all plans for options, RSUs, and employee share purchase rights was $2.1 million and $1.5 million for the second quarter of 2020 and 2019, respectively, and $5.0 million and $2.8 million for the six months ended June 26, 2020 and June 28, 2019, respectively.

Employee Share Purchase Plan

The 2017 Employee Stock Purchase Plan (the “2017 ESPP”) grants employees the ability to designate a portion of their base-pay to purchase ordinary shares at a price equal to 85% of the fair market value of our ordinary shares on the first or last day of each 6 month purchase period. Purchase periods begin on January 1 or July 1 and end on June 30 or December 31, or the next business day if such date is not a business day. Shares are purchased on the last day of the purchase period.

During the six months ended June 26, 2020, 16,520 ordinary shares were purchased by eligible employees under the 2017 ESPP. As of June 26, 2020, approximately 2.4 million ordinary shares remain available for purchase under the 2017 ESPP.

Segment Information

Note 10 – Segment Information

Our Chief Operating Decision Maker, the Chief Executive Officer, reviews our results of operations on a consolidated level and executive staff is structured by function rather than by product category. Therefore, we operate in one operating segment. Key resources, decisions, and assessment of performance are also analyzed on a company‑wide level.

Foreign operations are conducted primarily through our wholly owned subsidiaries in Singapore and Malaysia. Our principal markets include North America, Asia and, to a lesser degree, Europe. Sales by geographic area represent sales to unaffiliated customers.

All information on sales by geographic area is based upon the location to which the products were shipped. The following table sets forth sales by geographic area:

	Three Months Ended				Six Months Ended
	June 26, 2020		June 28, 2019		June 26, 2020		June 28, 2019

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). All intercompany balances and transactions have been eliminated upon consolidation. All dollar figures presented in tables in the notes to consolidated financial statements are in thousands, except per share amounts.

Year End

Year End

We use a 52- or 53-week fiscal year ending on the last Friday in December. The three months ended June 26, 2020 and June 28, 2019 were both 13 weeks. References to the second quarter of 2020 and 2019 refer to the three-month periods then ended. References to fiscal year 2020 refer to our fiscal year ending December 25, 2020.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods presented. We base our estimates and judgments on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from the estimates made by management. Significant estimates include the fair value of assets and liabilities acquired in acquisitions, estimated useful lives for long‑lived assets, allowance for doubtful accounts, inventory valuation, uncertain tax positions, fair value assigned to stock options granted, and impairment analysis for both definite‑lived intangible assets and goodwill.

Revenue Recognition

Revenue Recognition

We recognize revenue when control of promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. This amount is recorded as net sales in our consolidated statements of operations.

Transaction price – In most of our contracts, prices are generally determined by a customer-issued purchase order and generally remain fixed over the duration of the contract. Certain contracts contain variable consideration, including early-payment discounts and rebates. When a contract includes variable consideration, we evaluate the estimate of the variable consideration to determine whether the estimate needs to be constrained; therefore, we include the variable consideration in the transaction price only to the extent that it is probable that a significant reversal will not occur. Variable consideration estimates are updated at each reporting date. Historically, we have not incurred significant costs to obtain a contract. All amounts billed to a customer relating to shipping and handling are classified as net sales, while all costs incurred by us for shipping and handling are classified as cost of sales.

Performance obligations – Substantially all of our performance obligations pertain to promised goods (“products”), which are primarily comprised of fluid delivery subsystems, weldments, and other components. Most of our contracts contain a single performance obligation and are generally completed within twelve months. Product sales are recognized at a point-in-time, generally upon delivery, as such term is defined within the contract, as that is when control of the promised good has transferred. Products are covered by a standard assurance warranty, generally extended for a period of one to two years depending on the customer, which promises that delivered products conform to contract specifications. As such, we account for such warranties under ASC 460, Guarantees, and not as a separate performance obligation.

Contract balances – Accounts receivable represents our unconditional right to receive consideration from our customers. Accounts receivable are carried at invoice price less an estimate for doubtful accounts and estimated payment discounts. Payment terms vary by customer but are generally due within 15‑60 days. Historically, we have not incurred significant payment issues with our customers. We had no significant contract assets or liabilities on our consolidated balance sheets in any of the periods presented.

Commitments and Contingencies

Commitments and Contingencies

We are periodically involved in legal actions and claims that arise as a result of events that occur in the normal course of operations. The ultimate resolution of these actions is not expected to have a material effect on our financial position or results of operations. Subsequent to the end of the first quarter, but before the financial statements were issued, we reached a mutual settlement with the counterparty of a contract dispute and, accordingly, recorded a $1.4 million contract settlement loss to cost of sales, as the settlement provided evidence relating to a loss that existed at March 27, 2020.

Accounting Pronouncements Recently Adopted

Accounting Pronouncements Recently Adopted

In June 2016, the FASB issued ASU 2016‑13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.

In August 2018, the FASB issued ASU 2018‑15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350‑40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new guidance clarifies the accounting for implementation costs in cloud computing arrangements. We adopted the standard on the first day of the first quarter of 2020, and the adoption did not have a significant impact on our financial statements.
