Basis of Presentation

The condensed consolidated financial statements include the accounts of OSI Systems, Inc. and our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded in accordance with SEC rules and regulations applicable to interim unaudited financial statements. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. These condensed consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2018. The results of operations for the nine months ended March 31, 2019 are not necessarily indicative of the operating results to be expected for the full 2019 fiscal year or any future periods.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and costs of sales during the reporting period. The most significant of these estimates and assumptions for our company relate to contract revenue, profit and loss recognition, fair values of assets acquired and liabilities assumed in business combinations, values for inventories reported at lower of cost or net realizable value, stock-based compensation expense, income taxes, accrued warranty costs, and the recoverability, useful lives and valuation of recorded amounts of long-lived assets, identifiable intangible assets and goodwill.Changes in estimates are reflected in the periods during which they become known. Actual amounts may differ from these estimates and could differ materially.

Per Share Computations

We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. We compute diluted earnings per share by dividing net income available to common stockholders by the sum of the weighted average number of common shares and dilutive potential common shares outstanding during the period. Potential common shares consist of the shares issuable upon the exercise of stock options and restricted stock unit awards under the treasury stock method. In periods where a net loss is reported, basic and diluted net loss per share are the same since the effect of potential common shares is antidilutive and therefore excluded. The underlying equity component of the 1.25% convertible senior notes due 2022 (the “Notes”) discussed in Note 6 to the condensed consolidated financial statements will have no impact on diluted earnings per share until the average price of our common stock exceeds the conversion price because the principal amount of the Notes is intended to be settled in cash upon conversion.

The following table sets forth the computation of basic and diluted earnings (loss) per share (in thousands, except per share amounts):


	Three Months Ended March 31,				Nine Months Ended March 31,
	2018		2019		2018		2019
Net income (loss) available to common stockholders	$	2,553	$	19,626	$	(34,241)	$	48,135

Cash Equivalents

We consider all highly liquid investments with maturities of three months or less as of the acquisition date to be cash equivalents.

Our cash and cash equivalents totaled $107.6 million at March 31, 2019. These funds were held primarily by us and our subsidiaries in the United States, United Kingdom, Singapore, Malaysia, and Mexico, and to a lesser extent in India, Canada and Germany among others. We have cash holdings that exceed insured limits for financial institutions; however, we mitigate this risk by utilizing high credit quality financial institutions throughout the world.

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, marketable securities, derivative instruments, accounts receivable, accounts payable and debt instruments. The carrying values of financial instruments, other than long term debt instruments, are representative of their fair values due to their short term maturities. The carrying values of our long term debt instruments are considered to approximate their fair values because the interest rates of these instruments are variable or comparable to current rates available to us.

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. “Level 1” category includes assets and liabilities at quoted prices in active markets for identical assets and liabilities. “Level 2” category includes assets and liabilities from observable inputs other than quoted market prices. “Level 3” category includes assets and liabilities for which valuation techniques are unobservable and significant to the fair value measurement. As of June 30, 2018 and March 31, 2019, there were no assets where “Level 3” valuation techniques were used. Our contingent payment obligations related to acquisitions, which are further discussed in Note 9 to the condensed consolidated financial statements, are in the “Level 3” category for valuation purposes.

The fair values of our financial assets and liabilities as of June 30, 2018 and March 31, 2019 are categorized as follows (in thousands):


	June 30, 2018								March 31, 2019
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Assets:
Insurance company contracts	$	—	$	31,897	$	—	$	31,897	$	—	$	34,647	$	—	$	34,647
Interest rate contract		—		18		—		18		—		4		—		4
Total assets	$	—	$	31,915	$	—	$	31,915	$	—	$	34,651	$	—	$	34,651
Liabilities—contingent consideration	$	—	$	—	$	15,713	$	15,713	$	—	$	—	$	16,869	$	16,869

Derivative Instruments and Hedging Activity

Our use of derivatives consists of an interest rate swap agreement. The interest rate swap agreement was entered into to improve the predictability of cash flows from interest payments related to variable, LIBOR-based debt for the duration of the term loan described in Note 6. The interest rate swap matures in October 2019. The interest rate swap is considered an effective cash flow hedge and, as a result, the net gains or losses on such instrument were reported as a component of Other comprehensive income (loss) in the consolidated financial statements and are reclassified as net income when the hedge transaction settles.

Revenue Recognition

ASU 2014-09, Revenue from Contracts with Customers (Topic 606). In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09 and related amendments (“ASC 606”), which superseded all prior revenue recognition methods and industry-specific guidance. The core principle of ASC 606 is that an entity should recognize revenue to depict the transfer of control for promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the revenue principles, an entity is required to identify the contract(s) with a customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and recognize revenue when the performance obligation is satisfied (i.e., either over time or at a point in time). ASC 606 further requires that companies disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. On July 1, 2018, we adopted ASC 606 using the modified retrospective method, whereby the adoption does not impact any prior periods. We identified contracts not yet completed as of July 1, 2018 and applied the new guidance on a prospective basis.

Product Sales. We recognize revenue from sales of products upon shipment or delivery when control of the product transfers to the customer, depending on the terms of each sale, and when collection is probable. In the circumstance where terms of a product sale include subjective customer acceptance criteria, revenue is deferred until we have achieved the acceptance criteria unless the customer 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. Revenue from services includes installation and implementation of products and turnkey security screening services and after-market services. Generally, revenue from services is recognized over time as the services are performed. Revenues from out of warranty service maintenance contracts are recognized ratably over the respective terms of such contracts. Deferred revenue for such services arises from payments received from customers for services not yet performed.

Contract Revenue. Sales agreements with customers can be project specific, cover a period of time, and can be renewable periodically. The contracts may contain terms and conditions with respect to payment, delivery, installation, services, warranty and other rights. In certain instances, we consider an accepted customer order, governed by a master sales agreement, to be the contract with the customer when legal rights and obligations exist. Contracts with customers may include the sale of products and services, as discussed in the paragraphs above. In certain instances, contracts can contain multiple performance obligations as discussed in the paragraph below. According to the terms of a sale contract, we may receive consideration from a customer prior to transferring goods to the customer, and we record these prepayments as a contract liability. We also record deferred revenue, typically related to service contacts, when consideration is received before the services have been performed. We recognize customer deposits and deferred revenue as net sales after all revenue recognition criteria are met.

When determining revenue recognition for contracts, we use judgment based on our understanding of the obligations within 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. Certain agreements with customers include the sale of capital equipment involving multiple elements that may include civil works to prepare a site for the installation of equipment, manufacture and delivery of equipment, installation and integration of equipment, training of customer personnel to operate the equipment and after-market service of the equipment. We generally separate multiple elements in a contract into separate performance obligations if those elements are distinct, both individually and in the context of the contract. If multiple promises comprise a series of distinct services which are substantially the same and have the same pattern of transfer, they are combined and accounted for as a single performance obligation.

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 promise or bundle of promises 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 transaction value is first allocated using the observable price, which is generally a list price net of applicable discount or the price used to sell 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-deliverable arrangements. 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.

Effect of Adopting ASC 606. Adopting ASC 606 did not require any cumulative effect adjustment to retained earnings as of July 1, 2018 because the impact on retained earnings was immaterial. The impact to our condensed consolidated statements of operations is shown below for the three and nine month periods ended March 31, 2019 and for the balance sheet as of March 31, 2019.

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 11 to our condensed consolidated financial statements for additional details of revenues by reporting segment.

During the three and nine months ended March 31, 2019, we recognized additional revenue as a result of adopting ASC 606. This is primarily due to sales within our Security division where we met certain contractual performance obligations. As a result, this increased net income and accounts receivable and reduced inventories.

Contract Assets and Liabilities. We enter into contracts to sell products and provide services, and we recognize contract assets and liabilities that arise from these transactions. We recognize revenue and corresponding accounts receivable according to ASC 606 and, at times, recognize revenue in advance of the time when contracts give us the right to invoice a customer. We may also receive consideration, per the terms of a contract, from customers prior to transferring goods to the customer. We record customer deposits as a contract liability. Additionally, we may receive payments, most typically for service and warranty contracts, at the onset of the contract and before the services have been performed. In such instances, we record a deferred revenue liability. We recognize these contract liabilities as sales after all revenue recognition criteria are met. The table below shows the balance of contract assets and liabilities as of June 30, 2018 and March 31, 2019, including the change between the periods.

Deferred revenue—long-term		9,562		8,864		(698)	(7)	%

Remaining Performance Obligations. Remaining performance obligations related to ASC 606 represent the aggregate transaction price allocated to performance obligations under an original contract with a term greater than one year which are fully or partially unsatisfied at the end of the period.As of March 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $178.4 million. We expect to recognize revenue on approximately 44% of the remaining performance obligations over the next 12 months, and the remainder is expected to be recognized thereafter.

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.

Recently Adopted Accounting Pronouncements

Revenue Recognition

As discussed above, we adopted ASC 606 on July 1, 2018 using the modified retrospective method, whereby the adoption does not impact any prior periods.

Statement of Cash Flows

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update was issued with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230 and other topics. We adopted this ASU effective July 1, 2018 using the retrospective approach and the initial adoption had no material effect on our condensed consolidated statement of cash flows.

Income Taxes

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other than Inventory. The new guidance eliminates the exception for intra-entity transfers other than inventory and requires the recognition of current and deferred income taxes resulting from such a transfer when the transfer occurs. We adopted this ASU effective July 1, 2018 using the modified retrospective transition method resulting in a reclassification in the balance sheet of $3 million to decrease prepaid expenses and other assets and increase deferred tax assets.

Recently Issued Accounting Pronouncements Not Yet Adopted

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by leases with terms of more than 12 months. The ASU also will require qualitative and quantitative disclosures designed to give financial statement readers information on the amount, timing, and uncertainty of cash flows arising from leases. This ASU is effective for us in the first quarter of fiscal 2020 with early adoption permitted. We plan to adopt the new lease standard effective July 1, 2019, and apply it using the new transition method, under which an entity initially applies the new standard at the adoption date, versus at the beginning of the earliest period presented, and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We continue to assess and have not yet made a determination on whether to elect the package of transition practical expedients. In preparation for implementation, we plan to use a software solution to assist with the new reporting requirements and continue to assess the effect of the guidance on existing accounting policies and the consolidated financial statements. We expect the valuation of our right-of-use assets and lease liabilities, previously described as operating leases, to approximate the present value of our forecasted future lease commitments. We are currently implementing processes to comply with the measurement and disclosure requirements.

Retirement Benefit Plans

In August 2018, the FASB issued authoritative guidance under 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 are required to adopt this new guidance in the first quarter of fiscal 2021. We are currently evaluating the potential impact of the adoption of this guidance on our 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. This ASU requires implementation costs incurred by customers in cloud computing arrangements (i.e., hosting arrangements) to be capitalized under the same premises of authoritative guidance for internal-use software, and deferred over the noncancellable term of the cloud computing arrangements plus any option renewal periods that are reasonably certain to be exercised by the customer or for which the exercise is controlled by the service provider. We are required to adopt this new guidance in the first quarter of fiscal 2021. We are currently evaluating the potential impact of adoption of this guidance on our consolidated financial statements.
