SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business We have three reporting segments: (i) Security, providing security and inspection systems and turnkey security screening solutions; (ii) Healthcare, providing patient monitoring, diagnostic cardiology and connected care systems and associated accessories; and (iii) Optoelectronics and Manufacturing, providing specialized electronic components and electronic manufacturing services for our Security and Healthcare divisions, as well as third parties for applications in the defense and aerospace markets, among others. Through our Security segment, we provide security screening products and related services globally. These products fall into the following categories: baggage and parcel inspection; cargo and vehicle inspection; hold (checked) baggage screening; people screening; radiation detection; and explosive and narcotics trace detection. In addition to these products, we also provide site design, installation, training and technical support services to our customers. We also provide turnkey security screening solutions, which can include the construction, staffing and long-term operation of security screening checkpoints for our customers. Through our Healthcare segment, we design, manufacture, market and service patient monitoring, diagnostic cardiology, and connected care systems and associated accessories globally. These products are used by care providers in critical care, emergency and perioperative areas within hospitals as well as physicians’ offices, medical clinics and ambulatory surgery centers, among others. Through our Optoelectronics and Manufacturing segment, we design, manufacture and market optoelectronic devices and flex circuits and provide electronics manufacturing services globally for use in a broad range of applications, including aerospace and defense electronics, X-ray security and inspection systems and medical imaging, chemistry analysis and diagnostics instruments, telecommunications, scanners and industrial automations, internet of things (IoT) and consumer wearable products. This division provides products and services to OEM customers and end users as well as to our Security and Healthcare divisions. Consolidation Use of Estimates Cash and Cash Equivalents Our cash and cash equivalents totaled $80.6 million at June 30, 2021. Of this amount, approximately 71% was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in the United Kingdom, India, Malaysia, Singapore, Canada and Australia, and to a lesser extent in Albania and Germany among other countries. We have cash holdings in financial institutions that exceed insured limits for such financial institutions; however, we mitigate this risk by utilizing international financial institutions of high credit quality. Accounts Receivable Inventories Property and Equipment Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets We evaluate long-lived assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If impairment does exist, we measure the impairment loss and record it based on the discounted estimate of future cash flows. In estimating future cash flows, we group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other asset groups. Our estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors. Income Taxes Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The “Level 1” category includes assets and liabilities at quoted prices in active markets for identical assets and liabilities. The “Level 2” category includes assets and liabilities from observable inputs other than quoted market prices. The “Level 3” category includes assets and liabilities for which valuation techniques are unobservable and significant to the fair value measurement. The fair values of our financial assets and liabilities as of June 30, 2020 and 2021 are categorized as follows (in thousands): June 30, 2020 June 30, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets—Insurance company contracts $ — $ 37,155 $ — $ 37,155 $ — $ 47,113 $ — $ 47,113 Liabilities—Contingent consideration $ — $ — $ 13,867 $ 13,867 $ — $ — $ 19,431 $ 19,431 Derivative Instruments and Hedging Activity The net investment hedge has been designated as a hedge instrument and accounted for under Accounting Standards Codification (“ASC”) 815 “Derivatives and Hedging”. Hedge effectiveness is assessed using the spot method, consistent with guidance in ASC 815 whereby the change in fair value of the forward contract is recorded in the same manner as the related currency translation adjustments, within other comprehensive income, as the hedging instrument is expected to be fully effective unless the amount hedged exceeds the net investment in the foreign operation, or the foreign operation is liquidated. We settled the net investment hedge in the second quarter of fiscal 2021, and the amount recorded in other comprehensive loss was not significant. There were no net investment hedges outstanding as of June 30, 2021. The net gains or losses from the foreign currency forward contracts, which are not designated as hedge instruments, are reported in the consolidated income statement. We initiated these forward contracts in the first quarter of fiscal 2021 and the amounts reported in the consolidated income statement for the year ending June 30, 2021 were not significant. The fair value of our forward foreign exchange contracts is estimated using a standard valuation model and market-based observable inputs over the contractual term. Unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. As of June 30, 2021, we held foreign currency forward contracts with notional amounts totaling $26.1 million. Unrealized gains and losses from the forward currency forward contracts as of June 30, 2021 were not significant. There were no derivative instruments as of June 30, 2020. Revenue Recognition We recognize revenue under Accounting Standards Product Sales. include subjective customer acceptance criteria, revenue is deferred until we have achieved the customer acceptance criteria unless such acceptance criteria are perfunctory or inconsequential. We generally offer customers payment terms of less than one year. In cases when payment terms extend beyond one year, we consider whether the contract has a significant financing component. Service Revenue. Contract Revenue. When determining revenue recognition for contracts, we make judgments based on our understanding of the obligations in each contract. We determine whether or not customer acceptance criteria are perfunctory or inconsequential. The determination of whether or not customer acceptance terms are perfunctory or inconsequential impacts the amount and timing of revenue recognition. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product under warranty. Multiple Performance Obligations. In cases where obligations in a contract are distinct and thus require separation into multiple performance obligations, revenue recognition guidance requires that contract consideration be allocated to each distinct performance obligation based on its relative standalone selling price. The value allocated to each performance obligation is then recognized as revenue when the revenue recognition criteria for each distinct obligation or bundle of obligations has been met. The standalone selling price for each performance obligation is an amount that depicts the amount of consideration to which the entity expects to be entitled in exchange for transferring the good or service. When there is only one performance obligation associated with a contract, the entire sale value is attributed to that obligation. When a contract contains multiple performance obligations the standalone selling price is first estimated using the observable price, which is generally a list price net of applicable discount, or the price used to sell the good or service in similar circumstances. In circumstances when a selling price is not directly observable, we will estimate the standalone selling price using information available to us including our market assessment and expected cost plus margin. The timetable for fulfilment of each of the distinct performance obligations can range from completion in a short amount of time and entirely within a single reporting period to completion over several reporting periods. The timing of revenue recognition for each performance obligation may be dependent upon several milestones, including physical delivery of equipment, completion of factory acceptance test, completion of site acceptance test, installation and connectivity of equipment, certification of training of personnel and, in the case of after-market service deliverables, the passage of time (typically evenly over the post-warranty period of the service deliverable). We often provide a guarantee to support our performance under multiple performance obligations. In the event that customers are permitted to terminate such arrangements, the underlying contract typically requires payment for deliverables and reimbursement of costs incurred through the date of termination. We disaggregate revenue by reporting segment (Security, Optoelectronics and Manufacturing, and Healthcare) to depict the nature of revenue in a manner consistent with our business operations and to be consistent with other communications and public filings. Refer to Note 14 for additional details of revenues by reporting segment. Contract Assets and Liabilities. Practical Expedients. In cases where we are responsible for shipping after the customer has obtained control of the goods, we have elected to treat the shipping activities as fulfillment activities rather than as a separate performance obligation. Additionally, we have elected to capitalize the cost to obtain a contract only if the period of amortization would be longer than one year. We only give consideration to whether a customer agreement has a financing component if the period of time between transfer of goods and services and customer payment is greater than one year. Freight Research and Development Costs Stock-Based Compensation Impairment, Restructuring and Other Charges Credit Risk and Concentration Our cash and cash equivalents totaled $76.1 million and $80.6 million at June 30, 2020 and 2021, respectively. Of these amounts, approximately 63% and 71% was held by our foreign subsidiaries at June 30, 2020 and 2021, respectively. For cost, quality control, technological, and efficiency reasons, we purchase certain materials, parts, and components only from single vendors with whom we have ongoing relationships. We do, however, qualify second sources for many of our materials, parts, and components. While management believes that relying on key vendors improves the efficiency and reliability of business operations, relying on any one vendor for a significant aspect of business can have a significant negative impact on revenue and profitability if that vendor fails to perform at acceptable service levels for any reason, including financial difficulties of the vendor.

We recognize ROU lease assets and lease liabilities at lease commencement on our consolidated balance sheet based on the present value of lease payments over the lease term using a discount rate determined based on our incremental borrowing rate since the rate implicit in each lease is not readily determinable. We elected the package of practical expedients, which permits us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. We elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component. We also elected the hindsight practical expedient, which allows us to use hindsight in determining the lease term. We do not record an ROU asset and corresponding lease liability for leases with an initial term of one year or less ("short-term leases"). The terms in our leases may include options to extend or terminate the lease. We recognize ROU assets and liabilities when it is reasonably certain that we will exercise those options. Judgment is required in our assessment as to whether renewal or termination options are reasonably certain to be exercised and factors such as contractual terms compared to current market rates and the importance of the facility and location to our operations, among others, are considered. Lease payments are made in accordance with the lease terms, and lease expense, including short-term lease expense, is recognized on a straight-line basis over the lease term. We lease facilities and certain equipment under various operating lease agreements. The majority of our lease arrangements are comprised of fixed payments while certain of our other leases provide for periodic rent increases. Our leases may contain escalation clauses and renewal options. Most of the leases require us to pay for certain other costs such as common area maintenance and property taxes. Rent expense for leases with periodic rent increases or escalation clauses is recognized on a straight-line basis over the minimum lease term. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. We also have finance leases for fleet vehicles that are not material to the consolidated financial statements. Subsequent Events Recent Accounting Guidance Recently Adopted Accounting Pronouncements Retirement Benefit Plans In August 2018, the FASB issued authoritative guidance under Accounting Standards Update (“ASU”) 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU eliminates requirements for certain disclosures and requires additional disclosures under defined benefit pension plans and other post-retirement plans. We adopted this new guidance in the first quarter of fiscal 2021, and it did not have a significant impact on our disclosures in the consolidated financial statements. Intangibles In August 2018, the FASB issued authoritative guidance under ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. Reference Interest Rate In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which temporarily simplifies the accounting for contract modifications, including hedging relationships, due to the transition from LIBOR and other interbank offered rates to alternative reference interest rates. For example, entities can elect not to remeasure the contracts at the modification date or reassess a previous accounting determination if certain conditions are met. Additionally, entities can elect to continue applying hedge accounting for hedging relationships affected by reference rate reform if certain conditions are met. Modifications to debt agreements for a change in the reference interest rate will be accounted for by prospectively adjusting the effective interest rate. The new standard was effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. We are currently evaluating the impact of the transition from LIBOR to alternative reference interest rates; however, the adoption of this new guidance for modifications to contracts, if any, is not expected to have a significant impact on our consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted Convertible Debt In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. By removing those separation models, the interest rate of convertible debt instruments typically will be closer to the coupon interest rate. ASU 2020-06 also provides for certain disclosures with regard to convertible instruments and associated fair values. We are required to adopt this new guidance in the first quarter of fiscal 2023. Early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We intend to early adopt the new guidance on July 1, 2021 using the modified retrospective approach and expect to record a $19 million increase to retained earnings and a reduction of $27 million previously recorded in common stock as if there had been no equity component. Additionally, we also expect to record an increase to the convertible notes balance by approximately $10 million. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles of ASC 740 and is intended to improve consistency and simplify GAAP by clarifying and amending existing guidance for income taxes and related topics. We are required to adopt this new guidance in the first quarter of fiscal 2022. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. We are currently evaluating the potential impact of adoption of this guidance on our consolidated financial statements.

BUSINESS COMBINATIONS
BUSINESS COMBINATIONS	2. BUSINESS COMBINATIONS Under ASC 805, Business Combinations, the acquisition method of accounting requires us to record assets acquired less liabilities assumed in an acquisition at their estimated fair values at the date of acquisition. Any excess of the total estimated purchase consideration over the estimated fair value of the assets acquired less liabilities assumed should be recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customers, acquired technology, trade names, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. We may record adjustments to the assets acquired and liabilities assumed, with corresponding adjustments to goodwill, during the one-year post-acquisition measurement period as additional information becomes available. Upon the conclusion of the measurement period, any subsequent adjustments are reflected in reported earnings. Fiscal Year 2021 Business Acquisition In July 2020, we (through our Healthcare division) acquired a privately-held software development company for $3.0 million, plus up to $12.0 million in potential contingent consideration. The goodwill recognized for this business is deductible for income tax purposes. This acquisition was financed with available cash on hand. This business acquisition was not material to our consolidated financial statements. Accordingly, pro-forma historical results of operations and certain other disclosures related to this business have not been presented. Other Business Acquisitions In fiscal 2020 we paid In fiscal 2019 we paid an aggregate of $18.3 million, plus up to $6 million in future contingent consideration, which may be earned over a five-year period, for three business acquisitions. The majority of the goodwill recognized for these businesses are deductible for income tax purposes. These acquisitions were financed with cash on hand and borrowings under our credit facility. These business acquisitions, individually and in the aggregate, were not material to our consolidated financial statements. Accordingly, pro-forma historical results of operations related to these businesses have not been presented.

Software development costs incurred after establishing technological feasibility are capitalized on a product-by-product basis until the product is available for general release to customers at which time amortization begins. Annual amortization, charged to cost of goods sold, is the amount computed using the ratio that current revenues for a product bear to the total current and anticipated future revenues for that product. In the event that future revenues are not estimable, such costs are amortized on a straight-line basis over the remaining estimated economic life of the product. Amortizable assets that have not yet begun to be amortized are included in Thereafter in the table above. During fiscal 2019, 2020 and 2021, we capitalized software development costs in the amounts of $2.7 million, $11.9 million and $12.9 million, respectively.

IMPAIRMENT, RESTRUCTURING AND OTHER CHARGES	7. IMPAIRMENT, RESTRUCTURING AND OTHER CHARGES We endeavor to align our global capacity and infrastructure with demand by our customers as well as fully integrate acquisitions and thereby improve operational efficiency. During the year ended June 30, 2021, we incurred $7.2 million for exit activities associated with an expired turnkey contract in Mexico. Such exit costs include $2.8 million for employee terminations, $1.1 million for facility closure and other exit costs, direct transaction costs of $2.7 million, and $0.6 million for right-of-use asset impairment for a leased facility. We also incurred costs of $1.6 million for other employee terminations and $0.5 million for other facility closure costs for operational efficiency activities, $0.3 million for acquisition-related activities, and $0.5 million for certain legal charges, net of insurance reimbursements. During fiscal 2020, we incurred $0.4 million in costs for professional fees relating to acquisitions, $4.0 million in employee termination costs as part of operational efficiency initiatives, and $0.2 million in costs associated with the consolidation of facilities in our Security division. Additionally, legal fees and settlement costs resulted in a net recovery of $3.6 million as a result of insurance reimbursements of certain legal costs. During the year ended June 30, 2020, we also impaired an intangible asset for IPR&D in the Security division due to a strategic shift in the direction of the project and abandoned a non-core product line in our Healthcare division which resulted in the write-off of assets, including intangible and fixed assets. As a result, $5.5 million of assets, including intangible and fixed assets, were written off as we determined that these assets had no value and were permanently impaired.

BORROWINGS	8. BORROWINGS Revolving Credit Facility We have a revolving credit facility with an aggregate committed amount of up to $535 million which matures in April 2024. The credit facility includes a $300 million sub-limit for letters of credit. Under certain circumstances, we have the ability to increase the facility by the greater of $250 million or such amount as would not cause our secured leverage ratio to exceed a specified level. Borrowings under this facility bear interest at LIBOR plus a margin of 1.0% as of June 30, 2021 (which margin can range from 1.0% to 1.75% based on our consolidated net leverage ratio as defined in the credit facility). The LIBOR index is expected to be discontinued by the end of calendar year 2021. The terms of our credit facility allow for replacement if that occurs. Letters of credit reduce the amount available to borrow under the credit facility by their face value amount. The unused portion of the facility bears a commitment fee of 0.10% as of June 30, 2021 (which fee can range from 0.10% to 0.25% based on our consolidated net leverage ratio as defined in the credit facility). Our borrowings under the credit agreement are guaranteed by certain of our U.S.-based subsidiaries and are secured by substantially all of our assets and substantially all the assets of certain of our subsidiaries. The agreement contains various representations and warranties, affirmative, negative and financial covenants and conditions of default. As of June 30, 2021, there were no borrowings outstanding under the revolving credit facility and $63.2 million outstanding under the letters of credit sub facility.The amount available to borrow under the credit facility as of June 30, 2021 was $471.8 million. Loan amounts under the revolving credit facility may be borrowed, repaid and re-borrowed during the term. The principal amount of each revolving loan is due and payable in full on the maturity date. We have the right to repay each revolving loan in whole or in part from time to time without penalty. It is our practice to routinely borrow and repay several times per year under this revolving facility. Therefore, borrowings under the credit facility are included in current liabilities. As of June 30, 2021, we are in compliance with all financial covenants under this credit facility. 1.25% Convertible Senior Notes Due 2022 In February 2017, we issued $287.5 million of the Notes in a private offering. The Notes are governed by an indenture dated February 22, 2017. The maturity for the payment of principal is September 1, 2022. The Notes bear interest at the rate of 1.25% and are payable in cash semiannually in arrears on each March 1 and September 1. The Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries, as well as any of our existing and future indebtedness that may be guaranteed by our subsidiaries to the extent of such guarantees (including the guarantees of certain of our subsidiaries under our existing revolving credit facility). The Notes are convertible prior to March 1, 2022 only upon specified events and during specified periods and are, thereafter convertible, at any time, in each case at an initial conversion rate of 9.3056 per $1,000 principal amount of the Notes, which is equal to an initial conversion price of approximately $107.46 per share or a 38.5% premium to our stock price at the time of the issuance. The conversion rate is subject to adjustment upon certain events. Upon conversion, the indenture provides that the Notes may be settled, at our election, in shares of our common stock, cash or a combination of cash and shares of common stock. We have irrevocably elected a combination settlement method to satisfy the conversion obligation, which provides for us to settle the principal amount of the Notes in cash and to settle the excess conversion value, if any, in shares of common stock, as well as cash in lieu of fractional shares. We may redeem the Notes if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any period of 30 consecutive trading days. If we undergo a fundamental change, as defined in the indenture for the Notes, subject to certain conditions, holders of the Notes may require us to repurchase all or part of the Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The occurrence of a fundamental change will also result in the Notes becoming immediately convertible. Since the last reported sales price of our Common Stock did not exceed 130% of the conversion price for at least 20 trading days within any applicable period of 30 consecutive trading days during fiscal year 2021, the Notes are not yet convertible. Pursuant to ASC 470-20, we allocated the $287.5 million gross proceeds of the Notes between liability and equity components. The initial $242.4 million liability component was determined based on the fair value of similar debt instruments excluding the conversion feature for similar terms and priced on the same day the Notes were issued. The initial $45.1 million equity component represents the debt discount and was calculated as the difference between the fair value of the debt and the gross proceeds of the Notes. Issuance costs of $7.7 million were allocated between debt ($6.5 million) and equity ($1.2 million) components with the portion allocated to the debt presented as an offset against long term debt in the consolidated balance sheet and being amortized as interest expense over the life of the Notes using the effective interest method. The total interest expense recognized for the fiscal year ended June 30, 2021 related to the Notes was $13.4 million, which consisted of $3.6 million of contractual interest expense, $8.6 million of debt discount amortization and $1.2 million of amortization of debt issuance costs. For fiscal year ended June 30, 2020, the total interest expense was $13.0 million, which consisted of $3.6 million of contractual interest expense, $8.2 million of debt discount amortization and $1.2 million of amortization of debt issuance costs. For fiscal year ended June 30, 2019, the total interest expense was $12.6 million, which consisted of $3.6 million of contractual interest expense, $7.8 million of debt discount amortization and $1.2 million of amortization of debt issuance costs. As of June 30, 2020 and 2021, the unamortized debt discount was $19.1 million and $10.5 million, respectively, which was being amortized over the remaining contractual term to maturity of the Notes using an effective interest rate of 4.50%. The unamortized debt issuance cost of $2.5 million and $1.4 million as of June 30, 2020 and 2021, respectively, is amortized on a straight-line basis, which approximates the effective interest method, over the life of the Notes. Other Borrowings Several of our foreign subsidiaries maintain bank lines-of-credit, denominated in local currencies and U.S. dollars, primarily for the issuance of letters-of-credit. As of June 30, 2021, $65.7 million was outstanding under these letter-of-credit facilities. As of June 30, 2021, the total amount available under these credit facilities was $8.8 million. Long-term debt consisted of the following at June 30, 2020 and 2021 (in thousands): 2020 2021 1.25% convertible notes due 2022: Principal amount $ 287,500 $ 287,500 Unamortized discount (19,075) (10,494) Unamortized debt issuance costs (2,547) (1,372) 265,878 275,634 Other long-term debt 2,120 1,633 267,998 277,267 Less current portion of long-term debt (926) (846) Long-term portion of debt $ 267,072 $ 276,421 Fiscal year principal payments of long-term debt as of June 30, 2021 are as follows (in thousands): 2022 $ 846 2023 276,110 2024 241 2025 70 2026 and thereafter — Total $ 277,267

The 2012 Plan and the 2006 Plan are collectively referred to as the “OSI Plans.” We recorded stock-based compensation expense in the consolidated statements of operations as follows (in thousands): 2019 2020 2021 Cost of goods sold $ 732 $ 708 $ 760 Selling, general and administrative 23,876 22,546 25,457 Research and development 643 563 554 Stock-based compensation expense $ 25,251 $ 23,817 $ 26,771 As of June 30, 2021, total unrecognized compensation cost related to share-based compensation grants under the OSI Plans were estimated at $0.5 million for stock options and $13.9 million for restricted stock units (“RSUs”). We expect to recognize these costs over a weighted-average period of 1.9 years with respect to the stock options and 2.1 years for grants of RSUs. OSI Plans Awards are granted in the form of incentive options, nonqualified options, restricted stock awards, stock appreciation rights, RSUs, performance shares and stock bonuses, amongst other forms of equity, to qualified employees, directors and consultants. Under the OSI Plans, the exercise price of nonqualified options and incentive stock options may not be less than the fair market value of our Common Stock on the date of grant. The exercise price of nonqualified options and incentive stock options granted to individuals who own more than 10% of our voting stock may not be less than 110% of the fair market value of our Common Stock on the date of grant. Stock options granted under the OSI Plans typically vest over three years based on continued service. Restricted stock and RSUs typically vest over three to four years based on continued service. Certain restricted stock awards granted to senior management vest based on the achievement of pre-established performance criteria. Stock Option Fair Value Estimation Assumptions. Expected Dividend. Risk-Free Interest Rate. Expected Volatility. Expected Holding Period. Changes in assumptions can materially impact the estimated fair value of stock options. The weighted average assumptions used in the valuation model are presented in the table below. 2019 2020 2021 Expected dividend — — — Risk-free interest rate 2.6 % 1.6 % 0.4 % Expected volatility 28.0 % 26.0 % 26.0 % Expected holding period (in years) 4.5 4.5 4.5 The following summarizes stock option activity for fiscal years 2019, 2020 and 2021: Weighted- Average Weighted-Average Aggregate Number of Exercise Remaining Contractual Intrinsic Value Options Price Term (in thousands) Outstanding at June 30, 2018 677,525 32.80 Granted 19,259 73.37 Exercised (169,799) 32.11 Expired or forfeited (11,101) 70.50 Outstanding at June 30, 2019 515,884 $ 33.74 Granted 13,263 101.31 Exercised (201,150) 20.48 Expired or forfeited (1,693) 81.79 Outstanding at June 30, 2020 326,304 $ 44.41 Granted 22,171 82.17 Exercised (88,657) 35.19 Expired or forfeited (4,598) 80.46 Outstanding at June 30, 2021 255,220 $ 50.24 2.5 years $ 13,118 Exercisable at June 30, 2021 221,090 $ 44.80 1.5 years $ 12,567 The per-share weighted-average grant-date fair value of stock options granted under the OSI Plans was $20.45, $24.88 and $18.37 for fiscal 2019, 2020 and 2021, respectively. The total intrinsic value of options exercised during fiscal 2021 was $3.9 million.

The total fair value of shares vested during fiscal 2019, 2020 and 2021 was $25.8 million, $26.8 million, and $27.0 million, respectively. In December 2020, our shareholders authorized an increase of 1.65 million shares for the 2012 Plan resulting in a maximum pool of 7.1 million shares. As of June 30, 2021, there were approximately 2.1 million shares available for grant under the 2012 Plan. Under the terms of the 2012 Plan, RSUs and restricted stock granted from the pool of shares available for grant reduce the pool by 1.87 shares for each award granted. RSUs and restricted stock forfeited and returned to the pool of shares available for grant increase the pool by 1.87 shares for each award forfeited. We granted 97,514, 81,621, and 136,242 performance-based awards during fiscal 2019, 2020 and 2021, respectively. These performance-based RSU awards are contingent on the achievement of certain performance metrics. The payout related to these awards can range from zero to 400% of the original number of shares or units awarded. Employee Stock Purchase Plan We have an employee stock purchase plan under which eligible employees may purchase a limited number of shares of Common Stock at a discount of up to 15% of the market value of such stock at pre-determined, plan-defined dates. During the three years ended June 30, 2019, 2020 and 2021, employees purchased 70,857, 69,399, and 63,499 shares, respectively. As of June 30, 2021, there were 537,935 shares of our Common Stock available for issuance under the plan. Stock Repurchase Program During fiscal 2019, 2020 and 2021, we repurchased 288,316 shares, 562,707 shares and 452,005 shares, respectively, of Common Stock under our then current programs. In April 2020, the Board of Directors authorized a new share repurchase program of up to 1,000,000 shares of Common Stock. In August 2020, the Board of Directors increased the maximum number of shares to 3,000,000 shares authorized under the stock repurchase program. Repurchases may be made from time to time under the program through open-market purchases or privately-negotiated transactions at our discretion. Upon repurchase, the shares are restored to the status of authorized but unissued shares, and we record them as a reduction in the number of shares of Common Stock issued and outstanding in our consolidated financial statements. As of June 30, 2021, 2,547,995 shares were available for repurchase under the current program. Dividends We have not paid any cash dividends since the consummation of our initial public offering in 1997 and we do not currently intend to pay any cash dividends in the foreseeable future. Our Board of Directors will determine the payment of future cash dividends, if any. Certain of our current bank credit facilities restrict the payment of cash dividends and future borrowings may contain similar restrictions.

The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $9.4 million. We recognize potential interest and penalties related to income tax matters in income tax expense. As of June 30, 2021, we had accrued $1.4 million for interest and penalties. Our uncertain tax positions are related to tax years that remain subject to examination by the relevant tax authorities. These include fiscal years after 2017 for federal purposes, fiscal years after 2016 for state purposes and fiscal years after 2009 for various foreign jurisdictions. Facts and circumstances could arise that could cause us to reduce the liability for unrecognized tax benefits, including, but not limited to, settlement of income tax positions or expiration of statutes of limitation. Since the ultimate resolution of uncertain tax positions depends on many factors and assumptions, we are not able to estimate the range of potential changes in the liability for unrecognized tax benefits or the timing of such changes. A summary of activity of unrecognized tax benefits for fiscal 2020 and 2021 is as follows (in thousands). Balance at June 30, 2019 $ 11,386 Additions on tax positions for the current year 1,764 Additions on tax positions from prior years 451 Reduction in tax positions from prior year (291) Balance at June 30, 2020 $ 13,310 Additions on tax positions for the current year 5,937 Additions on tax positions from prior years 678 Reduction in tax positions from prior year (248) Balance at June 30, 2021 $ 19,677 Deferred income tax assets (liabilities) consisted of the following (in thousands): June 30, 2020 2021 Deferred income tax assets: Tax credit carryforwards $ 15,277 $ 16,767 Net operating loss carryforwards 4,241 3,745 Customer advances 2,725 2,819 Allowance for doubtful accounts 2,927 5,266 Inventory reserve 11,999 10,391 Inventory capitalization 2,762 489 Accrued liabilities 4,879 4,466 Operating lease liabilities 7,243 10,522 Stock and deferred compensation 9,911 12,323 Other assets 2,178 2,685 Total deferred income tax assets 64,142 69,473 Valuation allowance (17,371) (16,177) Net deferred income tax assets 46,771 53,296 Deferred income tax liabilities: Depreciation (1,459) (2,137) Amortization of intangible assets (27,907) (31,779) Withholding tax on unrepatriated foreign earnings (5,114) (6,851) Operating lease ROU assets (7,295) (10,355) State transition tax (1,754) (1,754) Convertible debt (4,432) (2,384) Prepaid expenses (1,399) (929) Other liabilities (143) (107) Total deferred income tax liabilities (49,503) (56,296) Net deferred income tax liability $ (2,732) $ (3,000) The components of the net deferred income tax liability are classified in the consolidated balance sheets as follows (in thousands): 2020 2021 Long term deferred income tax asset, included in other assets $ 3,114 $ 4,157 Long term deferred income tax liability (5,846) (7,157) Net deferred income tax liability $ (2,732) $ (3,000) The components of current taxes receivable and payable and prepaid taxes are classified in the consolidated balance sheets as follows (in thousands): 2020 2021 Current taxes receivable and prepaid taxes, included in prepaid expenses and other current assets $ 15,614 $ 10,383 Current taxes payable, included in other accrued expenses and current liabilities (4,086) (4,377) Net tax receivable $ 11,528 $ 6,006 As of June 30, 2021, we had state and foreign net operating loss carryforwards of approximately $25.7 million and $8.9 million, respectively. As of June 30, 2021, we had federal and state tax credit carryforwards of approximately $10.4 million and $8.9 million, respectively. Our credit carryforwards will begin to expire in the tax year ending June 30, 2034. We have established valuation allowances that relate to the net operating loss of certain subsidiaries, capital losses, and tax credits. During the year ended June 30, 2021, we recorded a net aggregated decrease of $1.2 million to these valuation allowances. We review the adequacy of individual valuation allowances and release such allowances when it is determined that it is more likely than not that the related benefits will be realized. We recognized all excess tax benefits and tax deficiencies as income tax expense or benefit in the current year. An income tax expense of approximately $1.4 million and $4.2 million was recognized in fiscal 2020 and 2021, respectively. The consolidated effective income tax rate differs from the federal statutory income tax rate due primarily to the following: June 30, 2019 2020 2021 Provision for income taxes at federal statutory rate 21.0 % 21.0 % 21.0 % Research and development tax credits (1.6) (1.6) (1.7) Foreign income subject to tax at other than federal statutory rate 2.9 (0.8) 0.6 Stock compensation (3.2) (6.7) (.9) Officers’ compensation 3.5 4.4 5.8 Change in valuation allowance (1.8) (1.3) (5.9) Unrecognized tax expense 0.1 1.2 4.2 Tax on foreign currency gains and losses 0.2 2.1 (0.2) State tax expense 1.6 1.1 1.2 U.S. tax on foreign earnings 1.0 (2.1) (1.8) Changes in prior year estimates — (6.4) — Global intangible low-taxed income, net of foreign tax credits 1.0 1.8 0.5 Foreign Derived Intangible Income Benefit (0.4) (0.6) (1.3) Withholding tax on foreign earnings — — 3.4 Other 0.5 0.5 — Effective income tax rate 24.8 % 12.6 % 24.9 % The provision for income taxes consists of provisions for federal, state, and foreign income taxes. We operate in an international environment with significant operations in various locations outside the U.S. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	11. COMMITMENTS AND CONTINGENCIES Acquisition-Related Contingent Obligations We account for such contingent payments for acquisitions which occurred through the end of fiscal year 2009 as additions to the purchase price of the acquired business. We made contingent payments relating to such acquisitions of $1.6 million and $1.0 million, respectively, during the fiscal years ended June 30, 2020 and 2021, respectively. For acquisitions completed after fiscal 2009, pursuant to ASC 805, the estimated fair value of these obligations is recorded as a liability at the time of the acquisition with subsequent revisions recorded in Selling, general and administrative expense in the consolidated financial statements. The estimated fair value measurements of contingent earn-out obligations are primarily based on unobservable inputs, which may include projected revenues, gross margins, operating income, and the estimated probability of achieving the earn-outs. These projections and probabilities are used to estimate future contingent earnout payments, which are discounted back to present value to compute contingent earnout liabilities. The following table provides a roll-forward from June 30, 2020 to June 30, 2021 of the contingent consideration liability, which is included in other accrued expenses and current liabilities, and other long-term liabilities in our consolidated balance sheets (in thousands): Beginning fair value, June 30, 2020 $ 13,867 Additions 7,304 Change in fair value (1,740) Payments on contingent earn-out obligations — Ending fair value, June 30, 2021 $ 19,431 Advances from Customers Environmental Contingencies We continue to investigate contamination of the soil and groundwater beneath the Hawthorne, California facility that resulted from unspecified on- and off-site releases occurring prior to our occupancy. We believe the releases are of a historical nature and not uncommon to the region in general. We continue to take voluntary actions, in cooperation with the local governing agency, to fully investigate the site in order to develop appropriate remedial actions. We have not accrued for loss contingencies relating to the Hawthorne facility or any other environmental matters because we believe that, although unfavorable outcomes may be possible, they are not considered by our management to be probable and reasonably estimable. If one or more of these environmental matters are resolved in a manner adverse to us, the impact on our business, financial condition, results of operations and cash flow could be material. Indemnifications and Certain Employment-Related Contingencies On December 31, 2017, we and Deepak Chopra, our Chief Executive Officer, entered into an amendment to Mr. Chopra’s employment agreement that, among other things, provides for a $13.5 million bonus payment to Mr. Chopra on or within 45 days of January 1, 2024 contingent upon Mr. Chopra’s continued employment with us through that date, subject to accelerated payout terms in the event of Mr. Chopra’s death or disability. The bonus is recorded in the financial statements over the remaining term of the employment agreement and is included in other long-term liabilities. Legal Proceedings Arkansas Teacher Retirement System et al. v. OSI Systems, Inc. et al. Kocen and Riley v. Chopra, et al. Arkansas Teacher Retirement System The SEC and the DOJ are conducting an investigation of trading in our securities and have each subpoenaed information regarding trading by executives, directors, and employees, as well as our operations and disclosures in and around the time of certain trades. With respect to these trading related matters, in fiscal year 2018, we took action with respect to a senior level employee. At this time, we are unable to predict what, if any, action may be taken by the DOJ or SEC as a result of these trading related investigations, or any penalties or remedial measures these agencies may seek. We place a high priority on compliance with our anticorruption and securities trading policies and are cooperating with each of the government investigations. We are involved in various other claims and legal proceedings arising in the ordinary course of business. In our opinion after consultation with legal counsel, the ultimate disposition of such proceedings is not likely to have a material adverse effect on our business, financial condition, results of operations or cash flows. We have not accrued for loss contingencies relating to any such matters because we believe that, although unfavorable outcomes in the proceedings are possible, they are not considered by management to be probable and reasonably estimable. If one or more of these matters are resolved in a manner adverse to our company, the impact on our business, financial condition, results of operations and cash flows could be material.

RELATED-PARTY TRANSACTIONS
RELATED-PARTY TRANSACTIONS	12. RELATED-PARTY TRANSACTIONS In 1994, we, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India. We own a 36% interest in the joint venture, our Chairman and Chief Executive Officer owns a 10.5% interest, and one of our Executive Vice Presidents owns a 4.5% ownership interest. Our initial investment in the joint venture was approximately $0.1 million. For each of the years ended June 30, 2019, 2020 and 2021 our equity earnings in the joint venture were less than $0.1 million. We, our Chairman and Chief Executive Officer and our Executive Vice President collectively control less than 50% of the board of directors voting power in the joint venture. As a result, we account for the investment under the equity method of accounting. The joint venture was formed for the purpose of the manufacture, assembly, service and testing of security and inspection systems and other products. Some of our subsidiaries are suppliers to the joint venture partner, which in turn manufactures and sells the resulting products. Sales to the joint venture partner for fiscal 2019, 2020 and 2021 were approximately $4.0 million, $2.3 million and $2.4 million, respectively. Receivables from the joint venture were $0.3 million and $0.5 million as of June 30, 2020 and 2021, respectively.

EMPLOYEE BENEFIT PLANS
EMPLOYEE BENEFIT PLANS	13. EMPLOYEE BENEFIT PLANS Employee Retirement Savings Plans We have various qualified employee retirement savings plans. Participants can contribute certain amounts to the plans and we match a certain portion of employee contributions. We contributed approximately $6.4 million, $6.5 million and $6.7 million to the plans for the fiscal years ended June 30, 2019, 2020 and 2021, respectively. Deferred Compensation Plan We have a deferred compensation plan, which meets the requirements for deferred compensation under Section 409A of the Internal Revenue Code. The plan provides that selected employees are eligible to defer up to 80% of their salaries and up to 100% of their bonuses. We may also make employer contributions to participant accounts in certain circumstances. The benefits under this plan are unsecured. Participants are generally eligible to receive payment of their vested benefit at the end of their elected deferral period or after termination of their employment for any reason or at a later date to comply with the restrictions of Section 409A. Discretionary company contributions and the related earnings are subject to a vesting schedule dependent upon years of service to us and, also, vest completely upon the participant’s disability or death while employed by us or immediately prior to a change of control. We made contributions of $0.5 million for each of fiscal year 2019, 2020 and 2021. As of June 30, 2021, we held assets of $32.8 million and liabilities of $32.3 million related to this plan. Assets related to this plan are included in other assets and liabilities related to this plan are included in other long-term liabilities in the consolidated balance sheets. The plan liabilities include accrued employer contributions not yet funded to the plan. Employee Pension Plans We sponsor a number of qualified and nonqualified pension plans for our employees at certain locations. In accordance with accounting standards for employee pension and postretirement benefits, we fully recognize the overfunded or underfunded status of each of our defined benefit plans as an asset or liability in the consolidated balance sheets. The asset or liability equals the difference between the fair value of the plans’ assets and their benefit obligations. The liabilities associated with underfunded plans are classified as noncurrent, except to the extent the fair value of the plans’ assets is less than the plans’ estimated benefit payments over the next 12 months . We measure our pension and postretirement benefit plans’ assets and benefit obligations as of June 30. The following provides a reconciliation of the changes in the plans’ benefit obligations and fair value of assets for fiscal years 2020 and 2021, and a statement of the funded status as of June 30, 2020 and 2021 (in thousands): 2020 2021 Change in Benefit Obligation Benefit obligation at beginning of year $ 14,059 $ 16,225 Translation adjustment (155) 700 Interest costs 442 477 Amendment 1,260 1,272 Actuarial (gain) loss 770 (45) Benefits paid (151) (195) Benefit obligation at end of year 16,225 18,434 Change in Plan Assets Fair value of plan assets at beginning of year 5,781 5,358 Translation adjustment (156) 710 Actual return on plan assets (160) 1,090 Benefits paid (107) (148) Fair value of plan assets at end of year 5,358 7,010 Funded status and net amount recognized $ (10,867) $ (11,424) Amount recognized in consolidated balance sheets consists of: Investments $ 226 $ 1,503 Accrued pension liability (11,093) (12,927) Accumulated other comprehensive income 3,424 4,319 One of our defined benefit pension plans is considered a nonqualified plan, therefore we have funded a separate rabbi trust which comprises insurance company contracts with fair values of $10.7 million and $14.3 million as of June 30, 2020 and 2021, respectively. These amounts are not included in the fair value of plan assets in the table above. The following table provides the net periodic benefit costs for the fiscal years ended June 30, (in thousands): 2019 2020 2021 Net Periodic Benefit Costs Interest costs $ 457 $ 442 $ 477 Service costs 223 — — Expected return on plan assets (270) (251) (242) Amortization of prior service costs 56 (61) 668 Recognized actuarial loss 103 34 75 Net periodic benefit cost $ 569 $ 164 $ 978 Plan Assumptions 2020 2021 Weighted average assumptions at year-end: Discount rate 2.7 % 2.6 % Expected return on plan assets 4.2 % 4.2 % Rate of compensation increase — % — % The long-term return on assets has been derived from the weighted average of assumed returns on each of the major asset categories. The weighted average is based on the actual proportion of each major asset class held, rather than a benchmark portfolio of assets. The expected returns for each major asset class have been derived from a combination of both historical market returns and current market data as well as the views of a range of investment managers. There is no assumed rate of compensation increase as most of the plan participants are retirees or no longer employed by OSI. Plan Assets and Investment Policy Fiscal year ended Fiscal year ended June 30, 2020 June 30, 2021 Proportion of Expected Rate Proportion of Expected Rate Fair Value of Return Fair Value of Return Equity securities 80 % 5.0 % 83 % 4.9 % Debt securities 19 % 1.0 % 16 % 0.8 % Cash 1 % 0.5 % 1 % 0.4 % Combined 100 % 4.2 % 100 % 4.2 % The defined benefit plans’ assets are invested in a range of pooled investment funds that provide access to a diverse range of asset classes. The investment objective is to maximize the investment return over the long term without exposing the fund to an unnecessary level of risk. Within this objective, it is recognized that benefits will be secured by the purchase of annuities at the time of employee retirement. The benchmark is to hold assets in both equity and debt securities. The proportion in each investment class is not mandated and is allowed to fluctuate with market movements. The equity holdings are maintained in balanced funds under the control of investment managers. Day-to-day equities selection decisions are delegated to investment managers, although these are monitored against performance and risk targets. Due to the nature of the pooled funds, there are no significant holdings in any single company (greater than 5% of the total assets). The investment strategy is reviewed on a regular basis, based on the results of third-party liability studies. Projected Benefit Payments The following table reflects estimated benefits payments, based upon the same assumptions used to measure the benefit obligation and net pension cost, as of June 30, 2021 (in thousands): Pension Benefits July 1, 2021 to June 30, 2022 198 July 1, 2022 to June 30, 2023 217 July 1, 2023 to June 30, 2024 5,862 July 1, 2024 to June 30, 2025 1,411 July 1, 2025 to June 30, 2026 1,897 July 1, 2026 to June 30, 2031 6,321 Company Contribution As of June 30, 2021, our weighted average contribution rate is under 1% of pensionable salaries.

Segment Information	14. SEGMENT INFORMATION We have determined that we operate in three identifiable industry segments: (a) security and inspection systems (Security division), (b) medical monitoring and diagnostic cardiology systems (Healthcare division) and (c) optoelectronic devices and manufacturing (Optoelectronics and Manufacturing division). We also have a corporate segment (Corporate) that includes executive compensation and certain other general and administrative expenses; expenses related to stock issuances and legal, audit and other professional service fees not allocated to industry segments. Both the Security and Healthcare divisions comprise primarily end-product businesses whereas the Optoelectronics and Manufacturing division primarily supplies components and subsystems to external OEM customers, as well as to the Security and Healthcare divisions.

Cash and Cash Equivalents	Cash and Cash Equivalents Our cash and cash equivalents totaled $80.6 million at June 30, 2021. Of this amount, approximately 71% was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in the United Kingdom, India, Malaysia, Singapore, Canada and Australia, and to a lesser extent in Albania and Germany among other countries. We have cash holdings in financial institutions that exceed insured limits for such financial institutions; however, we mitigate this risk by utilizing international financial institutions of high credit quality.

Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets	Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets We evaluate long-lived assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If impairment does exist, we measure the impairment loss and record it based on the discounted estimate of future cash flows. In estimating future cash flows, we group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other asset groups. Our estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors.

Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The “Level 1” category includes assets and liabilities at quoted prices in active markets for identical assets and liabilities. The “Level 2” category includes assets and liabilities from observable inputs other than quoted market prices. The “Level 3” category includes assets and liabilities for which valuation techniques are unobservable and significant to the fair value measurement. The fair values of our financial assets and liabilities as of June 30, 2020 and 2021 are categorized as follows (in thousands): June 30, 2020 June 30, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets—Insurance company contracts $ — $ 37,155 $ — $ 37,155 $ — $ 47,113 $ — $ 47,113 Liabilities—Contingent consideration $ — $ — $ 13,867 $ 13,867 $ — $ — $ 19,431 $ 19,431
Derivative Instruments and Hedging Activity	Derivative Instruments and Hedging Activity The net investment hedge has been designated as a hedge instrument and accounted for under Accounting Standards Codification (“ASC”) 815 “Derivatives and Hedging”. Hedge effectiveness is assessed using the spot method, consistent with guidance in ASC 815 whereby the change in fair value of the forward contract is recorded in the same manner as the related currency translation adjustments, within other comprehensive income, as the hedging instrument is expected to be fully effective unless the amount hedged exceeds the net investment in the foreign operation, or the foreign operation is liquidated. We settled the net investment hedge in the second quarter of fiscal 2021, and the amount recorded in other comprehensive loss was not significant. There were no net investment hedges outstanding as of June 30, 2021. The net gains or losses from the foreign currency forward contracts, which are not designated as hedge instruments, are reported in the consolidated income statement. We initiated these forward contracts in the first quarter of fiscal 2021 and the amounts reported in the consolidated income statement for the year ending June 30, 2021 were not significant. The fair value of our forward foreign exchange contracts is estimated using a standard valuation model and market-based observable inputs over the contractual term. Unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. As of June 30, 2021, we held foreign currency forward contracts with notional amounts totaling $26.1 million. Unrealized gains and losses from the forward currency forward contracts as of June 30, 2021 were not significant. There were no derivative instruments as of June 30, 2020.
Revenue Recognition	Revenue Recognition We recognize revenue under Accounting Standards Product Sales. include subjective customer acceptance criteria, revenue is deferred until we have achieved the customer acceptance criteria unless such acceptance criteria are perfunctory or inconsequential. We generally offer customers payment terms of less than one year. In cases when payment terms extend beyond one year, we consider whether the contract has a significant financing component. Service Revenue. Contract Revenue. When determining revenue recognition for contracts, we make judgments based on our understanding of the obligations in each contract. We determine whether or not customer acceptance criteria are perfunctory or inconsequential. The determination of whether or not customer acceptance terms are perfunctory or inconsequential impacts the amount and timing of revenue recognition. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product under warranty. Multiple Performance Obligations. In cases where obligations in a contract are distinct and thus require separation into multiple performance obligations, revenue recognition guidance requires that contract consideration be allocated to each distinct performance obligation based on its relative standalone selling price. The value allocated to each performance obligation is then recognized as revenue when the revenue recognition criteria for each distinct obligation or bundle of obligations has been met. The standalone selling price for each performance obligation is an amount that depicts the amount of consideration to which the entity expects to be entitled in exchange for transferring the good or service. When there is only one performance obligation associated with a contract, the entire sale value is attributed to that obligation. When a contract contains multiple performance obligations the standalone selling price is first estimated using the observable price, which is generally a list price net of applicable discount, or the price used to sell the good or service in similar circumstances. In circumstances when a selling price is not directly observable, we will estimate the standalone selling price using information available to us including our market assessment and expected cost plus margin. The timetable for fulfilment of each of the distinct performance obligations can range from completion in a short amount of time and entirely within a single reporting period to completion over several reporting periods. The timing of revenue recognition for each performance obligation may be dependent upon several milestones, including physical delivery of equipment, completion of factory acceptance test, completion of site acceptance test, installation and connectivity of equipment, certification of training of personnel and, in the case of after-market service deliverables, the passage of time (typically evenly over the post-warranty period of the service deliverable). We often provide a guarantee to support our performance under multiple performance obligations. In the event that customers are permitted to terminate such arrangements, the underlying contract typically requires payment for deliverables and reimbursement of costs incurred through the date of termination. We disaggregate revenue by reporting segment (Security, Optoelectronics and Manufacturing, and Healthcare) to depict the nature of revenue in a manner consistent with our business operations and to be consistent with other communications and public filings. Refer to Note 14 for additional details of revenues by reporting segment. Contract Assets and Liabilities. Practical Expedients. In cases where we are responsible for shipping after the customer has obtained control of the goods, we have elected to treat the shipping activities as fulfillment activities rather than as a separate performance obligation. Additionally, we have elected to capitalize the cost to obtain a contract only if the period of amortization would be longer than one year. We only give consideration to whether a customer agreement has a financing component if the period of time between transfer of goods and services and customer payment is greater than one year.

Credit Risk and Concentration	Credit Risk and Concentration Our cash and cash equivalents totaled $76.1 million and $80.6 million at June 30, 2020 and 2021, respectively. Of these amounts, approximately 63% and 71% was held by our foreign subsidiaries at June 30, 2020 and 2021, respectively. For cost, quality control, technological, and efficiency reasons, we purchase certain materials, parts, and components only from single vendors with whom we have ongoing relationships. We do, however, qualify second sources for many of our materials, parts, and components. While management believes that relying on key vendors improves the efficiency and reliability of business operations, relying on any one vendor for a significant aspect of business can have a significant negative impact on revenue and profitability if that vendor fails to perform at acceptable service levels for any reason, including financial difficulties of the vendor.

Leases	Leases —Right of use ("ROU") assets represent our right to use an underlying asset during the reasonably certain lease terms, and lease liabilities represent our obligation to make lease payments arising from the leases. We recognize ROU lease assets and lease liabilities at lease commencement on our consolidated balance sheet based on the present value of lease payments over the lease term using a discount rate determined based on our incremental borrowing rate since the rate implicit in each lease is not readily determinable. We elected the package of practical expedients, which permits us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. We elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component. We also elected the hindsight practical expedient, which allows us to use hindsight in determining the lease term. We do not record an ROU asset and corresponding lease liability for leases with an initial term of one year or less ("short-term leases"). The terms in our leases may include options to extend or terminate the lease. We recognize ROU assets and liabilities when it is reasonably certain that we will exercise those options. Judgment is required in our assessment as to whether renewal or termination options are reasonably certain to be exercised and factors such as contractual terms compared to current market rates and the importance of the facility and location to our operations, among others, are considered. Lease payments are made in accordance with the lease terms, and lease expense, including short-term lease expense, is recognized on a straight-line basis over the lease term. We lease facilities and certain equipment under various operating lease agreements. The majority of our lease arrangements are comprised of fixed payments while certain of our other leases provide for periodic rent increases. Our leases may contain escalation clauses and renewal options. Most of the leases require us to pay for certain other costs such as common area maintenance and property taxes. Rent expense for leases with periodic rent increases or escalation clauses is recognized on a straight-line basis over the minimum lease term. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. We also have finance leases for fleet vehicles that are not material to the consolidated financial statements.
Subsequent Events	Subsequent Events
Recent Accounting Guidance	Recent Accounting Guidance Recently Adopted Accounting Pronouncements Retirement Benefit Plans In August 2018, the FASB issued authoritative guidance under Accounting Standards Update (“ASU”) 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU eliminates requirements for certain disclosures and requires additional disclosures under defined benefit pension plans and other post-retirement plans. We adopted this new guidance in the first quarter of fiscal 2021, and it did not have a significant impact on our disclosures in the consolidated financial statements. Intangibles In August 2018, the FASB issued authoritative guidance under ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. Reference Interest Rate In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which temporarily simplifies the accounting for contract modifications, including hedging relationships, due to the transition from LIBOR and other interbank offered rates to alternative reference interest rates. For example, entities can elect not to remeasure the contracts at the modification date or reassess a previous accounting determination if certain conditions are met. Additionally, entities can elect to continue applying hedge accounting for hedging relationships affected by reference rate reform if certain conditions are met. Modifications to debt agreements for a change in the reference interest rate will be accounted for by prospectively adjusting the effective interest rate. The new standard was effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. We are currently evaluating the impact of the transition from LIBOR to alternative reference interest rates; however, the adoption of this new guidance for modifications to contracts, if any, is not expected to have a significant impact on our consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted Convertible Debt In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. By removing those separation models, the interest rate of convertible debt instruments typically will be closer to the coupon interest rate. ASU 2020-06 also provides for certain disclosures with regard to convertible instruments and associated fair values. We are required to adopt this new guidance in the first quarter of fiscal 2023. Early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We intend to early adopt the new guidance on July 1, 2021 using the modified retrospective approach and expect to record a $19 million increase to retained earnings and a reduction of $27 million previously recorded in common stock as if there had been no equity component. Additionally, we also expect to record an increase to the convertible notes balance by approximately $10 million. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 removes certain exceptions to the general principles of ASC 740 and is intended to improve consistency and simplify GAAP by clarifying and amending existing guidance for income taxes and related topics. We are required to adopt this new guidance in the first quarter of fiscal 2022. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. We are currently evaluating the potential impact of adoption of this guidance on our consolidated financial statements.
