Basis of Presentation

The condensed consolidated financial statements include the accounts of OSI Systems, Inc. and its 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 the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2017. The results of operations for the three months ended September 30, 2017 are not necessarily indicative of the operating results to be expected for the full 2018 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, market values for inventories reported at lower of cost or net realizable value, stock-based employee compensation expense, income taxes, accrued product 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 will likely 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. Stock options and stock awards to purchase 0.1 million shares of common stock for each of the three months ended September 30, 2016 and September 30, 2017, respectively, were excluded from the calculation because to include such options and awards would have been antidilutive. Prior to our adoption of ASU 2016-09 in the fourth quarter of fiscal 2017, we included tax benefits in assessing whether equity awards were dilutive and in our calculations of weighted average dilutive shares under the treasury stock method. The underlying equity component of the 1.25% convertible senior notes discussed in Note 6 to the condensed consolidated financial statements will have no impact to 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 per share (in thousands, except per share amounts):

	Three Months Ended September 30,
	2016		2017
Net income available to common stockholders	$	677	$	10,157

Weighted average shares outstanding—basic	18,943		18,778
Dilutive effect of equity awards	648		813

Weighted average shares outstanding—diluted	19,591		19,591

Basic earnings per share	$	0.04	$	0.54

Diluted earnings per share	$	0.03	$	0.52

Cash Equivalents

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

Our cash, cash equivalents, and investments totaled $192.0 million at September 30, 2017. Of this amount, approximately 99% was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were located primarily in Mexico, Malaysia and the United Kingdom, and to a lesser extent in India, Singapore, Germany and China among others. We intend to permanently reinvest a significant portion of our earnings from foreign operations, and we currently do not anticipate that we will need this cash in foreign countries to fund our U.S. operations. In the event that funds from foreign operations are needed to fund operations in the United States and if U.S. taxes have not been previously provided on the related earnings, we would provide for and pay additional U.S. taxes at the time we change our intention with regard to the reinvestment of those earnings.

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash, 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 the 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. There were no assets where “Level 3” valuation techniques were used. As further discussed in Note 9 to the condensed consolidated financial statements, our contingent payment obligations related to acquisitions are valued using “Level 3” valuation techniques. Such obligations are measured at fair value on a recurring basis.

The fair values of the our financial assets and liabilities as of June 30, 2017 and September 30, 2017 are categorized as follows (in thousands):

	June 30, 2017								September 30, 2017
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Assets:
Equity securities	$	254	$	—	$	—	$	254	$	231	$	—	$	—	$	231
Insurance company contracts	—		26,940		—		26,940		—		29,183		—		29,183
Interest rate contract	—		20		—		20		—		18		—		18

Total assets	$	254	$	26,960	$	—	$	27,214	$	231	$	29,201	$	—	$	29,432

Liabilities—Contingent payment obligations	$	—	$	—	$	11,840	$	11,840	$	—	$	—	$	13,902	$	13,902

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. 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.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are charged while assets are used in service and are generally computed using the straight-line method over the estimated useful lives of the assets taking into consideration any estimated salvage value. Amortization of leasehold improvements is calculated on the straight-line method over the shorter of the useful life of the asset or the lease term. Leased capital assets are included in property and equipment. Amortization of property and equipment under capital leases is included with depreciation expense. In the event that property and equipment are idle, as a result of excess capacity or the early termination, non-renewal or reduction in scope of a turnkey screening operation, such assets are assessed for impairment on a periodic basis.

Goodwill Impairment

Goodwill represents the excess purchase price over the estimated fair value of the assets acquired and liabilities assumed in a business combination. Goodwill is allocated to our segments based on the nature of the product line of the acquired business. The carrying value of goodwill is not amortized, but is annually tested for impairment during our second quarter and more frequently if there is an indicator of impairment. We assess qualitative factors of each of our three reporting units to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill.

Revenue Recognition

Product Sales. We recognize revenue from sales of products upon shipment when title and risk of loss passes and when terms are fixed and collection is probable. In an instance where terms of a product sale include subjective customer acceptance criteria, revenue is deferred until we have achieved the acceptance criteria unless customer acceptance terms are perfunctory or inconsequential.

Service Revenue. Revenue from services includes after-market services, installation and implementation of products and turnkey security screening services. Generally, revenue from services is recognized when 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.

Multiple-Deliverable Arrangements. We enter into certain agreements with customers for the sale of capital equipment that contain 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. The duration to fulfill each of these deliverables can range from completion in a short amount of time and entirely within a single reporting period to completion over several reporting periods. The general timing of revenue recognition for each deliverable 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).

Multiple-deliverable arrangements require that consideration be allocated to each deliverable based on its relative selling price and recognized as revenue when the revenue recognition criteria for each deliverable has been met. The arrangement is separated into more than one unit of accounting if both of the following criteria are met: (i) the delivered item has value to the customer on a stand-alone basis; and (ii) for an arrangement including a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially within our control. If these criteria are not met, the arrangement is accounted for as one unit of accounting and the recognition of revenue is deferred until delivery is complete or is recognized ratably over the contract period as appropriate. If these criteria are met, consideration is allocated at inception of the arrangement to all deliverables on the basis of the relative selling price. We have generally met these criteria for the multiple-deliverable arrangement as all of the deliverables in our arrangements have stand-alone value in that either the customer can resell that item or another vendor sells that item separately. We typically do not offer a general right of return in regards to our multiple-deliverable arrangements.

The selling price of each deliverable is determined by establishing vendor-specific objective evidence (“VSOE”), third party evidence (“TPE”) or best estimate of selling price (“BESP”) for each delivered item. Generally, either VSOE or TPE is determinable; however, in the few instances where neither VSOE nor TPE is determinable, we utilize our BESP in order to allocate consideration to those deliverables. BESP for our product deliverables is determined by utilizing a weighted average price approach. BESP for our service deliverables is determined primarily by utilizing a cost-plus margin approach, though in some instances average price per hour is used.

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.

Proportional Performance. In connection with the agreement with the Servicio de Administración Tributaria (“SAT”) in Mexico, revenue is recognized based upon proportional performance, measured by the actual number of labor hours incurred divided by the total estimated number of labor hours for the project. The impact of changes in the estimated labor hours to service the agreement is reflected in the period during which the change becomes known. In the SAT agreement, customer billings may be submitted for several separate deliverables, including monthly services, activation of services, training of customer personnel and consultation on the design and location of security scanning operations, among others. In the event that payments received from the customer exceed revenue recognition, deferred revenue is recorded.

Critical judgments made by management related to revenue recognition include the determination of 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. Concurrent with revenue recognition, we accrue reserves for estimated product return and warranty costs. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge regarding the product under warranty.

Recent Accounting Updates Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) amending revenue recognition requirements for multiple deliverable revenue arrangements. This update provides guidance on how revenue is recognized for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the goods or services. This determination is made in five steps: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The ASU is effective for fiscal years beginning after December 15, 2017 and for interim reporting periods within such fiscal years. Earlier adoption is permitted only for fiscal years beginning after December 15, 2016, including interim reporting periods within such fiscal years. We are in the process of selecting a transition method and our preliminary evaluation of the impact of this ASU indicates that it will not have a material impact on the timing of revenue recognition.

In January 2016, FASB issued an ASU which affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. This guidance retains the current accounting for classifying and measuring investments in debt securities and loans, but requires equity investments to be measured at fair value with subsequent changes recognized in net income, except for those accounted for under the equity method or requiring consolidation. The guidance also changes the accounting for investments without a readily determinable fair value and that do not qualify for the practical expedient permitted by the guidance to estimate fair value. A policy election can be made for these investments whereby estimated fair value may be measured at cost and adjusted in subsequent periods for any impairment or changes in observable prices of identical or similar investments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim reporting periods within such fiscal years. Early application is permitted. We have not yet adopted this ASU and are currently evaluating the impact it may have on our financial condition and results of operations.

In February 2016, the FASB issued an ASU which affects the accounting for leases. The guidance requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The amendment also will require qualitative and quantitative disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. This ASU is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within such fiscal years. Early application is permitted. We have not yet adopted this ASU and are currently evaluating the impact it may have on our financial condition and results of operations.

In August 2016, the FASB issued an ASU to address the diverse classifications being applied to cash receipts and payments in the reporting entities’ cash flow statement. This ASU addresses eight specific cash flow issues to reduce diversity in practice. This ASU is effective for fiscal years beginning after December 15, 2017, including interim reporting periods within such fiscal years. We have not yet adopted this ASU and are currently evaluating the impact it may have on our financial condition and results of operations.

Adoption of ASU 2015-11

Effective July 1, 2017, we adopted ASU 2015-11 “Simplifying the Measurement of Inventory.” This ASU requires an entity to measure in scope inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The adoption of this ASU did not have a material impact on our financial condition and results of operations.
