Accounting Policies [Abstract]

Summary of Significant Accounting Policies

BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States of America for interim financial information and with the instructions to the Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual consolidated financial statements have been condensed or omitted pursuant to those rules and regulations; however, in the opinion of management the financial information reflects all adjustments, consisting of adjustments of a normal recurring nature, necessary for fair presentation. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended July 3, 2020 which are contained in the Company’s Annual Report on Form 10-K filed with the SEC on August 18, 2020. The results for the third quarter and nine months ended April 2, 2021 are not necessarily indicative of the results to be expected for the full fiscal year.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

All references to the third quarter of fiscal 2021 are to the quarter ended April 2, 2021. There were 13-weeks during the third quarters ended April 2, 2021 and March 27, 2020, respectively. There were 39-weeks during the nine months ended April 2, 2021 and March 27, 2020, respectively.

USE OF ESTIMATES

The preparation of 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 dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

BUSINESS COMBINATIONS

The Company utilizes the acquisition method of accounting under ASC 805, Business Combinations, (“ASC 805”), for all transactions and events in which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and in establishing the acquisition date fair value as the measurement date for all assets and liabilities assumed. The Company also utilizes ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations.

FOREIGN CURRENCY

Local currencies are the functional currency for the Company’s subsidiaries in Switzerland, the United Kingdom, France, Japan, Spain and Canada. The accounts of foreign subsidiaries are translated using exchange rates in effect at period-end for assets and liabilities and at average exchange rates during the period for results of operations. The related translation adjustments are reported in Accumulated other comprehensive loss (“AOCL”) in shareholders’ equity. Gains (losses) resulting from non-U.S. currency transactions are included in Other expense, net in the Consolidated Statements of Operations and Comprehensive Income and were immaterial for all periods presented.

REVENUE RECOGNITION

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation.

Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 53% and 59% of revenues for the third quarter and nine months ended April 2, 2021, respectively. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 70% and 74% of revenues for the third quarter and nine months ended March 27, 2020, respectively.

The Company also engages in long-term contracts for development, production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated subsystems and related services. Long-term contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material contracts.

Total revenue recognized under long-term contracts over time was 47% and 41% of total revenues for the third quarter and nine months ended April 2, 2021, respectively. Total revenue recognized under long-term contracts over time was 30% and 26% of total revenues for the third quarter and nine months ended March 27, 2020, respectively.

The Company generally does not provide its customers with rights of product return other than those related to assurance warranty provisions that permit repair or replacement of defective goods over a period of 12 to 36 months. The Company accrues for anticipated warranty costs upon product shipment. The Company does not consider activities related to such assurance warranties, if any, to be a separate performance obligation. The Company does offer separately priced extended warranties which generally range from 12 to 36 months that are treated as separate performance obligations. The transaction price allocated to extended warranties is recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract.

All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.

ACCOUNTS RECEIVABLE

Accounts receivable, net, represents amounts that have been billed and are currently due from customers. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended as necessary. The allowance is based upon an assessment of the customer's credit worthiness, reasonable forecasts about the future, history with the customer, and the age of the receivable balance. The Company typically invoices a customer upon shipment of the product (or completion of a service) for contracts where revenue is recognized at a point in time. For contracts where revenue is recognized over time, the invoicing events are typically based on specified performance obligation deliverables or milestone events, or quantifiable measures of performance.

CONTRACT BALANCES

Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract assets are presented as unbilled receivables and costs in excess of billings on the Company’s Consolidated Balance Sheets. Contract liabilities consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty contracts, which are recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. Customer advances represent deposits received from customers on an order. Contract liabilities are included in deferred revenue and the long-term portion of deferred revenue is included within other non-current liabilities on the Company’s Consolidated Balance Sheets. Contract balances are reported in a net position on a contract-by-contract basis.

The contract asset balances were $138,378 and $90,289 as of April 2, 2021 and July 3, 2020, respectively. The contract asset balance increased due to growth in revenue recognized over time and timing of billable events under long-term contracts during the nine months ended April 2, 2021. The contract liability balances were $31,954 and $19,892 as of April 2, 2021 and July 3, 2020, respectively. The increase was due to a greater volume of long-term contracts with milestone billings across multiple programs.

Revenue recognized for the third quarter and nine months ended April 2, 2021 that was included in the contract liability balance at July 3, 2020 was $2,133 and $15,499, respectively. Revenue recognized for the third quarter and nine months ended March 27, 2020 that was included in the contract liability balance at June 30, 2019 was $1,564 and $9,838, respectively.

REMAINING PERFORMANCE OBLIGATIONS

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. The definition of remaining performance obligations excludes contracts with original expected durations of less than one year, as well as those contracts that provide the customer with the right to cancel or terminate the order with no substantial penalty, even if the Company’s historical experience indicates the likelihood of cancellation or termination is remote. As of April 2, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $352,229. The Company expects to recognize approximately 70% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.

WEIGHTED-AVERAGE SHARES

Weighted-average shares were calculated as follows:


	Third Quarters Ended		Nine Months Ended
	April 2, 2021	March 27, 2020	April 2, 2021	March 27, 2020
Basic weighted-average shares outstanding	55,146	54,604	55,033	54,514
Effect of dilutive equity instruments	380	523	401	557
Diluted weighted-average shares outstanding	55,526	55,127	55,434	55,071

Equity instruments to purchase 38 and 13 shares of common stock were not included in the calculation of diluted net earnings per share for the third quarter and nine months ended April 2, 2021, respectively, because the equity instruments were anti-dilutive. Equity instruments to purchase 3 and 136 shares of common stock were not included in the calculation of diluted net earnings per share for the third quarter and nine months ended March 27, 2020, respectively, because the equity instruments were anti-dilutive.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In August 2018, the FASB issued ASU No. 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715): Changes to the Disclosure Requirements for Defined Benefit Plans, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU remove disclosures that no longer are considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. For public business entities, the standard is effective for fiscal years ending after December 15, 2020. The ASU requires retrospective adoption and permits early adoption for all entities. The Company does not expect this guidance to have a material impact to its consolidated financial statements or related disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions for intraperiod tax allocations and deferred tax liabilities for equity method investments and add guidance as to whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This ASU is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company does not expect this guidance to have a material impact to its consolidated financial statements or related disclosures.

In March 2021, the FASB issued ASU No. 2021-03, Intangibles—Goodwill and Other (Topic 350): Accounting Alternative for Evaluating Triggering Events, an amendment of the FASB Accounting Standards Codification. The amendments in this ASU allow companies to elect not to monitor for goodwill impairment triggering events during the reporting period and instead, to evaluate the facts and circumstances as of the end of the reporting period to determine whether it is more likely than not that goodwill is impaired. This aligns the triggering event evaluation date with the reporting date, whether that date is an interim or annual reporting date. This ASU is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for both interim and annual financial statements that have not yet been issued or made available for issuance as of March 30, 2021. The Company does not expect this guidance to have a material impact to its consolidated financial statements or related disclosures.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

Effective July 4, 2020, the Company adopted ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which broadens the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. This ASU requires an entity to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. The Company will rely on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount and will exercise judgment in determining the relevant information and estimation methods that are appropriate in measurement of the credit losses. This adoption did not have a material impact to the Company's consolidated financial statements or related disclosures.

Effective July 4, 2020 the Company adopted ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates the requirement to measure the implied fair value of goodwill by assigning the fair value of a reporting unit to all assets and liabilities within that unit, the Step 2 test, from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited by the amount of goodwill in that reporting unit. This adoption did not have a material impact on the Company's consolidated financial statements or related disclosures.

Effective July 4, 2020 the Company adopted ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), an amendment of the FASB Accounting Standards Codification. The ASU provides guidance to determine whether to capitalize implementation costs of a cloud computing arrangement that is a service contract or expense as incurred. Costs of arrangements that do not include a software license should be accounted for as a service contract and expensed as incurred. This adoption did not have a material impact to the Company's consolidated financial statements or related disclosures.

Effective October 3, 2020, the Company adopted SEC Final Rule Release No. 33-10786, Amendments to Financial Disclosures About Acquired and Disposed Businesses, which includes amendments to the SEC's rules and forms related to the disclosure of financial information regarding acquired or disposed businesses. The amendments are intended to improve the financial information about acquired or disposed businesses provided to investors, facilitate more timely access to capital, and reduce the complexity and costs of preparing disclosures. Among other changes, the amendments impact SEC rules relating to: the definition of “significant” subsidiaries, requirements to provide financial statements for “significant” acquisitions, and the formulation and usage of pro forma financial information. The final rule is applicable for fiscal years beginning after December 31, 2020, with early adoption permitted as long as all amendments are adopted in their entirety. The Company has early adopted this final rule in conjunction with our acquisition of Physical Optics Corporation ("POC") on December 30, 2020. This adoption did not have a material impact on the Company's consolidated financial statements or related disclosures.

Acquisitions

PHYSICAL OPTICS CORPORATION ACQUISITION

On December 7, 2020, the Company signed a definitive agreement to acquire POC for a purchase price of $310,000, subject to net working capital and net debt adjustments. On December 30, 2020, the transaction closed and the Company acquired POC. Based in Torrance, California, POC more than doubles the Company's global avionics business and expands its collective footprint in the platform and mission management market. The Company funded the acquisition through a combination of cash on hand and the Company's existing revolving credit facility (the "Revolver").

As of January 1, 2021, the Company held $61,626 of Restricted cash and recorded a Deferred consideration liability for a purchase price payout to the employee shareholders of POC. This payout was made during the third quarter of fiscal 2021.

The following table presents the net purchase price and the fair values of the assets and liabilities of POC on a preliminary basis:


	Amounts
Consideration transferred
Cash paid at closing	$	251,229
Cash paid post closing	61,626
Working capital and net debt adjustment	(4,737)

Less cash acquired	(2,855)
Net purchase price	$	305,263

Estimated fair value of tangible assets acquired and liabilities assumed
Cash	$	2,855

Accounts receivable	24,966
Inventory	11,125
Fixed assets	23,236
Other current and non-current assets	14,968
Accounts payable	(3,777)
Accrued expenses	(4,502)

Other current and non-current liabilities	(42,987)
Estimated fair value of net tangible assets acquired	25,884
Estimated fair value of identifiable intangible assets	114,000
Estimated goodwill	168,234
Estimated fair value of net assets acquired	308,118
Less cash acquired	(2,855)
Net purchase price	$	305,263

The amounts above represent the preliminary fair value estimates as of April 2, 2021 and are subject to subsequent adjustment as the Company obtains additional information during the measurement period and finalizes its fair value estimates. The preliminary identifiable intangible asset estimate includes customer relationships of $81,000 with a useful life of 11 years, completed technology of $25,000 with a useful life of 9 years and backlog of $8,000 with a useful life of one year. Any subsequent adjustments to these fair value estimates occurring during the measurement period will result in an adjustment to goodwill.

The estimated goodwill of $168,234 largely reflects the potential synergies and expansion of the Company’s offerings across product lines and markets complementary to the Company’s existing products and markets and is not deductible for tax purposes. The goodwill from this acquisition is reported in the Mission reporting unit. The Company has not furnished pro forma information relating to POC because such information is not material to the Company’s financial results.

The revenues and income before income taxes from POC included in the Company's consolidated results for the third quarter ended April 2, 2021, were $38,492 and $1,065, respectively. The revenues and income before income taxes from POC included in the Company's consolidated results for the nine months ending April 2, 2021 were $38,709 and $782, respectively.

AMERICAN PANEL CORPORATION ACQUISITION

On September 23, 2019, the Company acquired American Panel Corporation (“APC”). Based in Alpharetta, Georgia, APC is a leading innovator in large area display technology for the aerospace and defense market. APC's capabilities are deployed on a wide range of next-generation platforms. The Company acquired APC for an all cash purchase price of $100,000, prior to net working capital and net debt adjustments. The Company funded the acquisition with cash on hand.

The following table presents the net purchase price and the fair values of the assets and liabilities of APC:


	Amounts
Consideration transferred
Cash paid at closing	$	100,826
Working capital and net debt adjustment	(5,952)
Liabilities assumed	2,454
Less cash acquired	(826)
Net purchase price	$	96,502

Fair value of tangible assets acquired and liabilities assumed
Cash	$	826
Accounts receivable	3,726
Inventory	11,233
Fixed assets	690
Other current and non-current assets	3,494
Accounts payable	(1,554)
Accrued expenses	(1,457)
Other current and non-current liabilities	(5,852)
Fair value of net tangible assets acquired	11,106
Fair value of identifiable intangible assets	33,200
Goodwill	53,022
Fair value of net assets acquired	97,328
Less cash acquired	(826)
Net purchase price	$	96,502

On September 23, 2020, the measurement period for APC expired. The identifiable intangible assets include customer relationships of $20,600 with a useful life of 11 years, completed technology of $10,400 with a useful life of 11 years and backlog of $2,200 with a useful life of two years.

The goodwill of $53,022 largely reflects the potential synergies and expansion of the Company's offerings across product lines and markets complementary to the Company's existing products and markets. The goodwill from this acquisition is reported under the Mission reporting unit. Since APC was a qualified subchapter S subsidiary, the acquisition is treated as an asset purchase for tax purposes. The Company has estimated the tax value of the intangible assets from this transaction and is amortizing the amount over 15 years for tax purposes. As of April 2, 2021, the Company had $48,840 of goodwill deductible for tax purposes.

Fair Value of Financial Instruments	9 Months Ended
Fair Value of Financial Instruments	Apr. 02, 2021
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments During the nine months ended April 2, 2021, the Company received gross proceeds and recorded a loss on sale of a cost-method investment of $1,538 and $426, respectively. The loss on sale of investment is included within Other expense, net in the Consolidated Statements of Operations and Comprehensive Income for the nine months ended April 2, 2021. The fair value of the investment was based on a quoted price of identical instruments in an active market and was recorded at cost within Other non-current assets in the Consolidated Balance Sheet prior to its sale. The carrying values of cash and cash equivalents, including money market funds, restricted cash, accounts receivable and payable, and accrued liabilities approximate fair value due to the short-term maturities of these assets and liabilities. The Company determined the carrying value of long-term debt approximated fair value due to variable interest rates charged on the borrowings, which reprice frequently.

Employee Benefit Plan	Apr. 02, 2021
Retirement Benefits [Abstract]
Employee Benefit Plan	Employee Benefit Plan PENSION PLAN The Company maintains a defined benefit pension plan (the “Plan”) for its Swiss employees, which is administered by an independent pension fund. The Plan is mandated by Swiss law and meets the criteria for a defined benefit plan under ASC 715, Compensation—Retirement Benefits (“ASC 715”), because participants of the Plan are entitled to a defined rate of return on contributions made. The independent pension fund is a multi-employer plan with unrestricted joint liability for all participating companies for which the Plan’s overfunding or underfunding is allocated to each participating company based on an allocation key determined by the Plan. The Company recognizes a net asset or liability for the Plan equal to the difference between the projected benefit obligation of the Plan and the fair value of the Plan’s assets as required by ASC 715. The funded status may vary from year to year due to changes in the fair value of the Plan’s assets and variations on the underlying assumptions of the projected benefit obligation of the Plan. The Plan's funded status at April 2, 2021 was a net liability of $12,261, which is recorded in Other non-current liabilities on the Consolidated Balance Sheet. The Company recorded a net gain of $30 and $92 in AOCL during the third quarter and nine months ended April 2, 2021. The Company recorded a net gain of $7 and $22 in AOCL during the third quarter and nine months ended March 27, 2020.

Stock-Based Compensation

STOCK INCENTIVE PLANS

At April 2, 2021, the aggregate number of shares authorized for issuance under the Company’s Amended and Restated 2018 Stock Incentive Plan (the “2018 Plan”) is 6,782 shares, including 710 shares rolled into the 2018 Plan that were available for future grant under the Company’s 2005 Stock Incentive Plan, as amended and restated (the “2005 Plan”) and 3,000 shares approved by the Company's shareholders on October 28, 2020. The 2018 Plan replaced the 2005 Plan. The shares authorized for issuance under the 2018 Plan will continue to be increased by any future cancellations, forfeitures or terminations (other than by exercise) of awards under the 2005 Plan. The foregoing does not affect any outstanding awards under the 2005 Plan, which remain in full force and effect in accordance with their terms. The 2018 Plan provides for the grant of non-qualified and incentive stock options, restricted stock, stock appreciation rights and deferred stock awards to employees and non-employees. Stock options must be granted with an exercise price of not less than 100% of the fair value of the Company’s common stock on the date of grant and the options generally have a term of seven years. There were 4,645 shares available for future grant under the 2018 Plan at April 2, 2021.

As part of the Company's ongoing annual equity grant program for employees, the Company grants performance-based restricted stock awards to certain executives and employees pursuant to the 2018 Plan. Performance awards vest based on the requisite service period subject to the achievement of specific financial performance targets. Based on the performance targets, some of these awards require graded vesting which results in more rapid expense recognition compared to traditional time-based vesting over the same vesting period. The Company monitors the probability of achieving the performance targets on a quarterly basis and may adjust periodic stock compensation expense accordingly based on its determination of the likelihood for reaching targets. The performance targets generally include the achievement of internal performance targets in relation to a peer group of companies.

EMPLOYEE STOCK PURCHASE PLAN

At April 2, 2021, the aggregate number of shares authorized for issuance under the Company’s 1997 Employee Stock Purchase Plan, as amended and restated (“ESPP”), is 2,300 shares, including 500 shares approved by the Company's shareholders on October 28, 2020. Under the ESPP, rights are granted to purchase shares of common stock at 85% of the lesser of the market value of such shares at either the beginning or the end of each six-month offering period. The ESPP permits employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s compensation as defined in the ESPP. There were 46 and 41 shares issued under the ESPP during the nine months ended April 2, 2021 and March 27, 2020, respectively. Shares available for future purchase under the ESPP totaled 483 at April 2, 2021.

Segment Reporting [Abstract]

Operating Segment, Geographic Information and Significant Customers

Operating segments are defined as components of an enterprise evaluated regularly by the Company's CODM in deciding how to allocate resources and assess performance. During the first quarter of fiscal 2021, the Company reorganized its internal reporting unit structure to align with the Company's market and brand strategy as well as promote scale as the organization continues to grow. The Company evaluated this reorganization under ASC 280 to determine whether this change has impacted the Company's single operating and reportable segment. The Company concluded this change had no effect given the CODM continues to evaluate and manage the Company on the basis of one operating and reportable segment. The Company utilized the management approach for determining its operating segment in accordance with ASC 280.

The geographic distribution of the Company’s revenues as determined by country in which the Company's legal subsidiary is domiciled is summarized as follows:

The Company offers a broad family of products designed to meet the full range of requirements in compute-intensive, signal processing, image processing and command and control applications. To maintain a competitive advantage, the Company seeks to leverage technology investments across multiple product lines and product solutions.

The Company’s products are typically compute-intensive and require extremely high bandwidth and high throughput. These systems often must also meet significant SWaP constraints for use in aircraft, unmanned aerial vehicles, ships and other platforms and be ruggedized for use in harsh environments. The Company's products transform the massive streams of digital data created in these applications into usable information in real time. The systems can scale from a few processors to thousands of processors.

In recent years, the Company completed a series of acquisitions that changed its technological capabilities, applications and end markets. As these acquisitions and changes occurred, the Company's proportion of revenue derived from the sale of components in different technological areas, and modules, sub-assemblies and integrated subsystems which combine technologies into more complex diverse products has shifted. The following tables present revenue consistent with the Company's strategy of expanding its technological capabilities and program content. As additional information related to the Company’s products by end user, application, product grouping and/or platform is attained, the categorization of these products can vary over time. When this occurs, the Company reclassifies revenue by end user, application, product grouping and/or platform for prior periods. Such reclassifications typically do not materially change the underlying trends of results within each revenue category.

The following table presents the Company's net revenue by end user for the periods presented:

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Apr. 02, 2021
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies LEGAL CLAIMS The Company is subject to litigation, claims, investigations and audits arising from time to time in the ordinary course of its business. Although legal proceedings are inherently unpredictable, the Company believes that it has valid defenses with respect to any matters currently pending against the Company and intends to defend itself vigorously. The outcome of these matters, individually and in the aggregate, is not expected to have a material impact on the Company’s cash flows, results of operations, or financial position. INDEMNIFICATION OBLIGATIONS The Company’s standard product sales and license agreements entered into in the ordinary course of business typically contain an indemnification provision pursuant to which the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with any patent, copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. Such provisions generally survive termination or expiration of the agreements. The potential amount of future payments the Company could be required to make under these indemnification provisions is, in some instances, unlimited. PURCHASE COMMITMENTS As of April 2, 2021, the Company has entered into non-cancelable purchase commitments for certain inventory components and services used in its normal operations. The purchase commitments covered by these agreements are for less than one year and aggregate to $145,019. OTHER As part of the Company's strategy for growth, the Company continues to explore acquisitions or strategic alliances. The associated acquisition costs incurred in the form of professional fees and services may be material to the future periods in which they occur, regardless of whether the acquisition is ultimately completed. The Company may elect from time to time to purchase and subsequently retire shares of common stock in order to settle employees’ tax liabilities associated with vesting of a restricted stock award or exercise of stock options. These transactions would be treated as a use of cash in financing activities in the Company's Consolidated Statements of Cash Flows.

Revenue Recognition

REVENUE RECOGNITION

All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities. Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract assets are presented as unbilled receivables and costs in excess of billings on the Company’s Consolidated Balance Sheets. Contract liabilities consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers, but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues. Deferred service revenue primarily represents amounts invoiced to customers for annual maintenance contracts or extended warranty contracts, which are recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. Customer advances represent deposits received from customers on an order. Contract liabilities are included in deferred revenue and the long-term portion of deferred revenue is included within other non-current liabilities on the Company’s Consolidated Balance Sheets. Contract balances are reported in a net position on a contract-by-contract basis.

Accounts Receivables

ACCOUNTS RECEIVABLEAccounts receivable, net, represents amounts that have been billed and are currently due from customers. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The Company provides credit to customers in the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended as necessary. The allowance is based upon an assessment of the customer's credit worthiness, reasonable forecasts about the future, history with the customer, and the age of the receivable balance. The Company typically invoices a customer upon shipment of the product (or completion of a service) for contracts where revenue is recognized at a point in time. For contracts where revenue is recognized over time, the invoicing events are typically based on specified performance obligation deliverables or milestone events, or quantifiable measures of performance.
