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 second quarter and six months ended January 1, 2021 are not necessarily indicative of the results to be expected for the full fiscal year.

All references to the second quarter of fiscal 2021 are to the quarter ended January 1, 2021. There were 13-weeks during the second quarters ended January 1, 2021 and December 27, 2019, respectively. There were approximately 26-weeks during the six months ended January 1, 2021 and December 27, 2019, respectively.

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.

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.

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.

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 61% and 62% of revenues for the second quarter and six months ended January 1, 2021, respectively. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 79% and 76% of revenues for the second quarter and six months ended December 27, 2019, 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 39% and 38% of total revenues for the second quarter and six months ended January 1, 2021, respectively. Total revenue recognized under long-term contracts over time was 21% and 24% of total revenues for the second quarter and six months ended December 27, 2019, 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.

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 customers’ 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 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 $119,346 and $90,289 as of January 1, 2021 and July 3, 2020, respectively. The contract asset balance increased due to growth in revenue recognized and timing of billable events under long-term contracts over time during the six months ended January 1, 2021. The contract liability balances were $33,887 and $19,892 as of January 1, 2021 and July 3, 2020, respectively. The increase was due to a greater number of long-term contracts with milestone billings across multiple programs.

Revenue recognized for the second quarter and six months ended January 1, 2021 that was included in the contract liability balance at July 3, 2020 was $4,336 and $13,366, respectively. Revenue recognized for the second quarter and six months ended December 27, 2019 that was included in the contract liability balance at June 30, 2019 was $2,898 and $8,274, respectively.

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 January 1, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $410,275. The Company expects to recognize approximately 69% of its remaining performance obligations as revenue in the next 12 months and the balance thereafter.

Equity instruments to purchase 114 and 2 shares of common stock were not included in the calculation of diluted net earnings per share for the second quarter and six months ended January 1, 2021, respectively, because the equity instruments were anti-dilutive. Equity instruments to purchase 419 and 297 shares of common stock were not included in the calculation of diluted net earnings per share for the second quarter and six months ended December 27, 2019, respectively, because the equity instruments were anti-dilutive.

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 is currently evaluating the effect that ASU 2019-12 will have on its consolidated financial statements and related disclosures.

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 its 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.
