Consolidation —The consolidated financial statements include the accounts of OSI Systems, Inc. and its wholly-owned and majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Investments in joint ventures over which the Company has significant influence but does not have voting control are accounted for using the equity method. Investments over which the Company does not have significant influence are accounted for using the cost method. Pending Acquisition —On June 20, 2016, OSI Systems, Inc. and American Science and Engineering, Inc. signed a definitive agreement pursuant to which the Company will acquire AS&E for $37.00 in cash per share of common stock of AS&E for a total purchase price of approximately $269 million. The Company intends to fund the transaction with a combination of AS&E's cash on hand and money borrowed under its revolving credit facility. As of June 30, 2016, AS&E reported cash and cash equivalents of $74 million. The completion of the transaction is subject to the satisfaction of customary conditions, including, among others: (i) the requisite approval of AS&E's shareholders, (ii) the expiration or termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR Act") and (iii) the absence of any order or injunction issued by any court or governmental authority in the United States preventing the consummation of the transaction. The transaction is expected to close by December 31, 2016. Use of Estimates —The preparation of financial statements in conformity with U.S. 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 the Company relate to contract revenue, profit and loss recognition, fair values of assets acquired and assumed in business combinations, market values for inventories reported at lower of cost or market, 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 differ from these estimates and could differ materially. Reclassifications —Certain reclassifications have been made to prior year amounts within the consolidated balance sheet to conform to the current year's presentation. The Company early adopted accounting standards update ("ASU") 2015-17, Balance Sheet Classification of Deferred Income Taxes, which amends the classification of deferred taxes. Deferred tax assets and liabilities will now be classified as non-current. Previously, the deferred income tax assets and liabilities had to be separated into current and non-current. The Company applied the ASU retrospectively, which resulted in reclassifications to the consolidated balance sheet as of June 30, 2015. In addition, unrelated to the adoption of ASU 2015-17, certain accounts were grouped differently than had been presented in the consolidated balance sheet as of June 30, 2015. The following table summarizes these reclassifications as follows (in thousands): Changes to Consolidated Balance Sheet as of June 30, 2015 As previously presented DR (CR) Reclassifications Pursuant to ASU 2015-17 Other Reclassifications Current DR (CR) Deferred income tax asset ) — Other assets Income tax payable ) — — Other accrued expenses and current liabilities ) ) ) Advances from customers—non-current ) — Deferred income tax liability ) ) Other long-term liabilities ) ) ) — — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net decrease to working capital ) — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net decrease to total assets ) — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash Equivalents —The Company considers all highly liquid investments purchased with maturities of approximately three months or less as of the acquisition date to be cash equivalents. Accounts Receivable —The Company monitors collections and payments from its customers and maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Components of accounts receivable consisted of (in thousands): June 30, 2015 2016 Accounts receivables $ $ Less allowance for doubtful accounts ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Inventories —Inventories are generally stated at the lower of cost (first-in, first-out) or market. The Company writes down inventory for slow-moving and obsolete inventory based on assessments of future demands, market conditions and customers who may be experiencing financial difficulties. If these factors are less favorable than those projected, additional inventory write-downs may be required. 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 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 or if any indicators of impairment exist. Certain fixed assets related to the Company's turnkey security screening program in Mexico are not currently in use. As of June 30, 2016, the net value of these assets is approximately $15 million, which is included in property and equipment in the condensed consolidated balance sheet. Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets —Goodwill represents the excess purchase price of net tangible and intangible assets acquired in business combinations over their estimated fair value. Goodwill is allocated to the Company's 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 the Company's second quarter and more often if there is an indicator of impairment. Intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. The Company assesses qualitative factors of each of its 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. Such assessments indicated that it is not more likely than not that the fair value of each reporting unit is less than its carrying amount, including goodwill. Thus, the Company has determined that it is not necessary to proceed with the two-step goodwill impairment test. There was no goodwill impairment for each of three fiscal years ended June 30, 2016. The Company evaluates 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, the Company measures the impairment loss and records it based on the discounted estimate of future cash flows. In estimating future cash flows, the Company groups assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other asset groups. The Company's 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 —Deferred income taxes are provided for temporary differences between the financial statement and income tax basis of the Company's assets and liabilities, based on enacted tax rates. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Income tax accounting standards prescribe a two-step process for the financial statement measurement and recognition of a tax position taken or expected to be taken in a tax return. The first step involves the determination of whether it is more likely than not (greater than 50 percent likelihood) that a tax position will be sustained upon examination, based on the technical merits of the position. The second step requires that any tax position that meets the more-likely-than-not recognition threshold be measured and recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The income tax accounting standards also provide guidance on the accounting for related interest and penalties, financial statement classification and disclosure. The cumulative effect of applying these standards is to be reported as an adjustment to the opening balance of retained earnings in the period of adoption. See note 8 for additional information. Fair Value of Financial Instruments —The Company's 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 the Company's 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 the Company. 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 whose 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, the Company's 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 our financial assets and liabilities as of June 30, 2015 and 2016 are categorized as follows (in thousands): June 30, 2015 June 30, 2016 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Equity securities $ $ $ — $ $ $ — — $ Insurance company contracts — — — — Interest rate contract — ) — ) — ) — ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total assets $ $ $ — $ $ $ $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities—Contingent payment obligations $ — $ — $ $ $ — $ — $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative Instruments and Hedging Activity —The Company's 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 in the consolidated financial statements and are reclassified as net income when the hedge transaction settles. Revenue Recognition —The Company recognizes revenue from sales of products upon shipment when title and risk of loss passes, and when terms are fixed and collection is probable. 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. The portion of revenue for the sale attributable to installation is deferred and recognized when the installation service is provided. In an instance where terms of sale include subjective customer acceptance criteria, revenue is deferred until the Company has achieved the acceptance criteria. Concurrent with the revenue recognition, the Company accrues estimated product return reserves and warranty expenses. 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 recognized. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product under warranty. In instances where a contract calls for multiple deliverables and such deliverables qualify as separate units of accounting, the Company may recognize revenue based on the value of the respective deliverables identified in the underlying contract. 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 this 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. In the event that revenue recognition exceeds payments received from the customer, unbilled receivables are recorded. Revenues from out-of-warranty service maintenance contracts are recognized ratably over the term of such contracts. For services not derived from specific maintenance contracts, revenues are recognized as the services are performed. Deferred revenue for such services arises from payments received from customers for services not yet performed. On occasion, the Company receives advances from customers that are amortized against future customer payments pursuant to the underlying agreements. Such advances are classified in the condensed consolidated balance sheets as either a current or long-term liability depending on when the Company estimates the corresponding amortization to occur. Freight —The Company records shipping and handling fees it charges to its customers as revenue and related costs as cost of goods sold. Research and Development Costs —Research and development costs are those costs related to the development of a new product, process or service, or significant improvement to an existing product, process or service. Such costs are charged to operations as incurred. Stock-Based Compensation —Stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the employee's requisite service period for all stock-based awards granted or modified. Certain restricted awards vest based on the achievement of pre-established performance criteria. The fair value of performance-based awards is estimated at the date of grant based upon the probability that the specified performance criteria will be met, adjusted for estimated forfeitures. Each quarter the Company updates the assessment of the probability that the specified performance criteria will be achieved and adjusts the estimate of the fair value of the performance-based awards if necessary. The Company amortizes the fair value of performance-based awards over the requisite service period for each separately vesting tranche of the award. See note 7 to the consolidated financial statements. Impairment, Restructuring and Other Charges —The Company accounts for certain charges related to restructuring activities, litigation, acquisition-related costs and other non-routine charges as Impairment, restructuring and other charges in the consolidated financial statements. See note 5 for additional information about these restructuring charges. Credit Risk and Concentration —Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. The Company restricts investments in cash equivalents to financial institutions with high credit standing. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company's worldwide customer base. As of June 30, 2015 and 2016, no customer accounted for greater than 10% of accounts receivable. SAT accounted for 12% and 14% of revenues for the fiscal years ended June 30, 2015 and 2016, respectively. The Company performs ongoing credit evaluations of its customers' financial condition and maintains allowances for potential credit losses. The Company relies primarily on a vendor that provides key components to the Optoelectronics and Manufacturing division. 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. Foreign Currency Translation —The Company transacts business in various foreign currencies. In countries where the functional currency of the underlying operations has been determined to be the local country's currency, revenues and expenses of operations outside the United States are translated into United States dollars using average exchange rates while assets and liabilities of operations outside the United States are translated into United States dollars using period-end exchange rates. The effects of foreign currency translation adjustments are included in stockholders' equity as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. Transaction gains and losses, which were included in the Company's consolidated statement of operations, amounted to a gain (loss) of approximately $(1.8) million, $2.1 million and $(0.8) million for the fiscal years ended June 30, 2014, 2015 and 2016, respectively. Business Combinations —The Company allocates the fair value of purchase consideration to the tangible and intangible assets acquired, and liabilities assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is 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, and 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. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. During the year ended June 30, 2016, the Company acquired all of the outstanding shares of capital stock of a distributor and manufacturer of electronic components in the United Kingdom, a distributor and manufacturer of flex circuit and touch panel design products in California and a security equipment service company in Brazil. The combined purchase prices consisted of cash payments at closing of $17.8 million, holdbacks of $2.6 million for potential indemnity claims and $13.8 million for the fair value of contingent consideration. The indemnity holdbacks are payable in fiscal 2017, if not used for indemnification claims. The combined purchase prices were allocated to the fair values of the net tangible and intangible assets. The combined allocations of intangible assets consisted of $25.3 million of goodwill and $8.3 million of identifiable intangible assets, which was comprised of $1.2 million of technology, $6.0 million of customer relationships, $0.9 million of trademarks and trade names, and $0.2 million of non-compete covenants. Earnings per Share —Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the sum of the weighted average number of common and dilutive potential common shares outstanding. Potential common shares consist of the shares issuable upon the exercise of stock options and restricted stock or units awards under the treasury stock method. During the fiscal years ending June 30, 2014 and 2015, respectively, the number of stock options and stock awards excluded from the calculation because they were antidilutive was de minimis. Stock option and stock awards to purchase 0.1 million shares of common stock for the fiscal year ending June 30, 2016 were excluded for the calculation because to do so would have been antidilutive. The following table sets forth the computation of basic and diluted earnings per share for the fiscal years ended June 30 (in thousands, except earnings per share data): 2014 2015 2016 Net income available to common stockholders $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding—basic Dilutive effect of equity awards ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding—diluted ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic earnings per share $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted earnings per share $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Warranty Provision —The Company offers its customers warranties on many of the products that it sells. These warranties typically provide for repairs and maintenance of the products if problems arise during a specified time period after original shipment. Concurrent with the sale of products, the Company records a provision for estimated warranty expenses with a corresponding increase in cost of goods sold. The Company periodically adjusts this provision based on historical experience and anticipated expenses. The Company charges actual expenses of repairs under warranty, including parts and labor, to this provision when incurred. The warranty provision is included in the Other accrued expenses and current liabilities in the consolidated balance sheets, whose activity for each of the three fiscal years ended June 30, 2016 is summarized in the following table (in thousands) Warranty provision as of June 30, 2013 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2014 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2015 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2016 $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 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 to depict 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 that reporting period. Earlier application is permitted only as of fiscal years beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has not yet selected a transition method and is currently evaluating the impact this ASU may have on its financial condition and results of operations. In July 2015, FASB issued an ASU amending some of the guidance on subsequent measurement of inventory. This ASU affects companies that are using first-in, first-out or average cost, or any other methods besides last-in, first out or the retail inventory method. This ASU is effective for fiscal years beginning after December 15, 2016, including interim reporting periods within that reporting period. The amendments in this ASU should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its financial condition and results of operations. In September 2015, FASB issued an ASU simplifying the measurement-period adjustments for acquisitions. This update provides guidance on how an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This amendment requires the acquirer to recognize adjustments to the provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined rather than retrospectively. This ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within that reporting period. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its financial condition and results of operations. 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, and interim periods within that reporting period. Early application is permitted. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its 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, and interim periods within that reporting period. Early application is permitted. The Company has not yet adopted this update and is currently evaluating the impact it may have on its financial condition and results of operations. In March 2016, the FASB issued an ASU relating to employee share-based payment accounting. This guidance simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classifica

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 2014, 2015 and 2016, the Company capitalized software development costs in the amount of $3.0 million, $3.0 million and $2.7 million, respectively.

LINE-OF-CREDIT BORROWINGS AND DEBT
LINE-OF-CREDIT BORROWINGS AND DEBT	6. LINE-OF-CREDIT BORROWINGS AND DEBT The Company has a $450 million revolving credit facility maturing May 2019. The credit facility includes a $375 million sub-limit for letters of credit. The Company has the ability to increase the facility by $200 million under certain circumstances. Borrowings under this facility bear interest at LIBOR plus a margin of 1.25% as of June 30, 2016. This margin is determined by the Company's consolidated leverage ratio and may range from 1.25% to 2.0%. Letters of credit reduce the amount available to borrow by their face value. The unused portion of the facility bears a commitment fee of 0.20% as of June 30, 2016 but this can range from 0.20% to 0.35% based on the Company's consolidated leverage ratio. The Company's borrowings under the credit agreement are guaranteed by certain of the Company's U.S.-based subsidiaries and are secured by substantially all of the assets of the Company and certain subsidiaries. The agreement contains various representations and warranties, affirmative, negative and financial covenants, and conditions of default customary for financing agreements of this type. As of June 30, 2016, there was $125 million outstanding under the revolving credit facility and $6.2 million outstanding under the letters-of-credit sub-facility. As of June 30, 2016, the Company believes that it is in compliance with all related covenants to this credit facility. Several of the Company's foreign subsidiaries maintain bank lines-of-credit, denominated in local currencies and U.S. dollars, to meet short-term working capital requirements and for the issuance of letters-of-credit. As of June 30, 2016, $37.1 million was outstanding under these letter-of-credit facilities, while no debt was outstanding. As of June 30, 2016, the total amount available under these credit facilities was $19.1 million, with a total cash borrowing sub-limit of $1.3 million. In September 2012, the Company entered into a term loan agreement for $11.1 million to fund the acquisition of land and a building in the state of Washington. The loan, which bears interest at LIBOR plus 1.25%, is payable on a monthly basis over seven years. Concurrent with entering into the floating rate loan, the Company entered into an interest rate swap agreement that effectively locks the interest rate of the loan to 2.2% per annum for the term of the loan.

Upon stockholder approval of the 2012 Plan, the Company ceased to make grants under the 2006 Plan. The Company recorded stock-based-compensation expense in the consolidated statement of operations as follows (in thousands): 2014 2015 2016 Cost of goods sold $ $ $ Selling, general and administrative Research and development ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stock based compensation expense Less: Related income tax benefit ) ) ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Stock based compensation expense, net $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2016, total unrecognized compensation cost related to share-based compensation grants were estimated at $0.8 million for stock options and $12.0 million for restricted stock and restricted stock units ("RSUs") under the OSI Plans. The Company expects to recognize these costs over a weighted-average period of 1.8 years with respect to the options and 2.0 years for grants of restricted stock and RSUs. Employee Stock Purchase Plan —The Company has 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, 2014, 2015 and 2016, employees purchased 29,185, 65,706 and 60,375 shares, respectively. As of June 30, 2016, there were 893,119 shares of the Company's Common Stock available for issuance under the plan. OSI Plans In September 2012, the Company's Board of Directors approved the 2012 Plan, and in December 2012 the stockholders adopted the 2012 Plan. The 2012 Plan serves as the successor to the 2006 Plan. No new awards will be issued under the 2006 Plan as of the date of stockholder approval of the 2012 Plan. Outstanding awards under the 2006 Plan continue to be subject to the terms and conditions of the 2006 Plan. Under the 2012 Plan, the Company is authorized to grant awards 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 the Company's 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 the Company's voting stock may not be less than 110% of the fair market value of the Company's 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. The Company estimates the fair value of its stock options at the date of grant using the Black-Scholes option-pricing valuation model. The Company's valuation model is affected by the Company's stock price as well as weighted average assumptions for a number of subjective variables described below. Expected Dividend. Expected dividend is based on historical patterns and the Company's anticipated dividend payments over the expected holding period. Risk-Free Interest Rate. The risk-free interest rate for stock options is based on U.S. Treasuries for a maturity matching the expected holding period. Expected Volatility. Expected volatility is based on the Company's historical share price volatility matching the expected holding period. No single method of estimating volatility is proper under all circumstances and to the extent that a company can derive implied volatility based on the trading of its financial instruments on a public market, it may be appropriate to use both implied and historical volatility in its assumptions. The Company has certain financial instruments that are publicly traded from which the Company can derive the implied volatility. Therefore, the Company used implied and historical volatility for valuing its stock options. The Company believes that implied and historical volatility is a better indicator of expected volatility because it is generally reflective of both historical volatility and expectations of how future volatility will differ from historical volatility. Expected Holding Period. The Company uses historical stock option exercise data to estimate the 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. 2014 2015 2016 Expected dividend % % % Risk-free interest rate % % % Expected volatility % % % Expected holding period (in years) The following summarizes stock option activity for fiscal years 2014, 2015 and 2016: Number of Options Weighted- Average Exercise Price Weighted-Average Remaining Contractual Term Aggregate Intrinsic Value (in thousands) Outstanding at June 30, 2013 Granted Exercised ) Expired or forfeited ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding at June 30, 2014 Granted Exercised ) Expired or forfeited ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding at June 30, 2015 Granted Exercised ) Expired or forfeited ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding at June 30, 2016 4.0 years $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exercisable at June 30, 2016 $ 3.7 years $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The per-share weighted-average grant-date fair value of stock options granted under the OSI Plans was $20.78, $19.26 and $20.66 for fiscal 2014, 2015 and 2016, respectively. The total intrinsic value of options exercised during fiscal 2016 was $6,077,000.

The total fair value of shares vested during fiscal 2014, 2015 and 2016 was $11.2 million, $11.2 million and $27.3 million, respectively. As of June 30, 2016, there were approximately 2.0 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. The Company granted 160,922, 151,469 and 139,300 performance-based awards during fiscal 2014, 2015 and 2016, respectively. These performance-based restricted stock and RSU awards are contingent on the achievement of certain performance metrics. The payout can range from zero to 250% of the original number of shares or units awarded.

The $4.9 million represents the amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate. The Company recognizes potential interest and penalties related to income tax matters in income tax expense. As of June 30, 2016, the Company had accrued $0.5 million for interest and penalties. The Company's uncertain tax positions are related to tax years that remain subject to examination by the relevant tax authorities. These include fiscal years after 2011 for federal purposes, fiscal years after 2010 for state purposes and fiscal years after 2005 for various foreign jurisdictions. Facts and circumstances could arise that could cause the Company 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, the Company is 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 2014, 2015 and 2016 is as follows (in thousands). Balance as July 1, 2014 $ Additions on tax positions for the current year Additions on tax positions from prior years Reduction in tax position from prior year ) ​ ​ ​ ​ ​ Balance at June 30, 2015 $ Additions on tax positions for the current year Additions on tax positions from prior years Reduction in tax position from prior year ) ​ ​ ​ ​ ​ Balance at June 30, 2016 $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The Company does not provide for U.S. income taxes on the undistributed earnings of its foreign subsidiaries as it is the Company's intention to utilize those earnings in the foreign operations for an indefinite period of time. At June 30, 2016, undistributed earnings of the foreign subsidiaries amounted to approximately $577 million. The amount of unrecognized deferred tax liability related to these temporary differences is estimated to be approximately $202 million. The amount of tax payable could be significantly impacted by the source location and amount of the distribution, the underlying tax rate already paid on the earnings, foreign withholding taxes and the opportunity to use foreign tax credits. Deferred income tax assets (liabilities) consisted of the following (in thousands): June 30, 2015 2016 Deferred income tax assets: Tax credit carryforwards $ $ Net operating loss carryforwards Customer advances Allowance for doubtful accounts Inventory reserve Inventory capitalization Accrued liabilities Stock & deferred compensation Other assets ​ ​ ​ ​ ​ ​ ​ ​ Total deferred income tax assets Valuation allowance ) ) ​ ​ ​ ​ ​ ​ ​ ​ Net deferred income tax assets ​ ​ ​ ​ ​ ​ ​ ​ Deferred income tax liabilities: Depreciation ) ) State income taxes ) ) Amortization of intangible assets ) ) Prepaid expenses ) ) Other liabilities ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total deferred income tax liabilities ) ) ​ ​ ​ ​ ​ ​ ​ ​ Net deferred tax asset $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The components of the net deferred income tax asset are classified in the consolidated balance sheets as follows (in thousands): 2015 2016 Long term deferred income tax asset, included in other assets Long term deferred income tax liability ) ) ​ ​ ​ ​ ​ ​ ​ ​ Net deferred income tax asset $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The components of current taxes receivable and payable and prepaid taxes are classified in the consolidated balance sheets as follows (in thousands): 2015 2016 Current taxes receivable and prepaid taxes, included in prepaid expenses and other current assets $ $ Current taxes payable ) ) ​ ​ ​ ​ ​ ​ ​ ​ Net tax receivable ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2016, the Company had federal, state, and foreign net operating loss carryforwards of approximately $36.1 million, $47.7 million and $28.7 million, respectively. As of June 30, 2016, the Company had federal and state research and development tax credit carryforwards of approximately $9.6 million and $3.8 million, respectively. As of June 30, 2016, the Company had foreign tax credit carryforwards of $7.3 million. The Company's credit carryforwards will begin to expire in the tax year ending June 30, 2018. The Company has established valuation allowances that relate to the net operating loss of certain subsidiaries, foreign tax credits and R&D credits. During the year ended June 30, 2016, the Company recorded a net aggregated increase of $1.7 million to these valuation allowances. The Company reviews the adequacy of individual valuation allowances and releases such allowances when it is determined that it is more likely than not that the related benefits will be realized. The Company recognizes excess tax benefits associated with the exercise of stock options directly to stockholders' equity only when realized. Accordingly, deferred tax assets are not recognized for net operating losses resulting from excess tax benefits. As of June 30, 2016, deferred tax assets do not include approximately $4.7 million of these excess tax benefits from employee stock option exercises that are a component of the Company's net operating loss carry forwards. Accordingly, additional paid-in capital will be increased up to an additional $4.7 million if and when such excess tax benefits are realized. However, to the extent additional paid-in capital has been recognized for qualifying excess tax deductions from previous share-based payments, the write off of the deferred tax asset when the tax deduction is less than recognized compensation cost is charged to additional paid-in capital, with any remainder charged to provision for income taxes. The consolidated effective income tax rate differs from the federal statutory income tax rate due primarily to the following: June 30, 2014 2015 2016 Provision for income taxes at federal statutory rate % % % UK Patent Box benefit — ) — Impact to tax rate as a result of accelerating depreciation of certain foreign assets — — Research and development tax credits ) ) ) Foreign income subject to tax at other than federal statutory rate ) ) ) Change in valuation allowance ) Unrecognized tax benefit ) ) Tax on foreign currency gains and losses — — Transaction costs — — US Tax on Foreign Earnings Non-taxable earnings from acquisitions ) ) ) Mexico imputed income or expense ) ) Other ) ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective income tax rate % % % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The provision for income taxes consists of provisions for federal, state, and foreign income taxes.

Certain leases provide for periodic rent increases and may contain escalation clauses and renewal options. Rent expense totaled $9.9 million, $10.0 million and $9.0 million for fiscal years 2014, 2015 and 2016, respectively. Contingent Acquisition Obligations —Under the terms and conditions of the purchase agreements associated with certain acquisitions, the Company may be obligated to make additional payments based on the achievement by the acquired operations of certain sales or profitability milestones. The maximum amount of such future payments under arrangements with contingent consideration caps is $34.7 million as of June 30, 2016. In addition, one of the purchase agreements the Company entered into requires royalty payments through 2022 based on the license of, or sales of products containing, the technology of CXR Limited, a company acquired in 2004. For acquisitions that occurred prior to fiscal year 2010, the Company accounts for such contingent payments as an addition to the purchase price of the acquired business. Otherwise, the estimated fair value of these obligations is recorded as a liability at the time of the acquisition in the consolidated balance sheets with subsequent revisions reflected in the consolidated statements of operations. As of June 30, 2015 and 2016, $17.2 million and $17.1 million of contingent payment obligations, respectively, are included in Other accrued expenses and current liabilities and Other long-term liabilities in the accompanying consolidated balance sheets. During fiscal 2016, additional contingent consideration of $13.8 million was recorded as a result of three acquisitions consummated during the period, $0.8 million of contingent consideration was paid, and the liability was reduced by $13.1 million due to revaluation and is included as a reduction to Selling, general and administrative expense in the consolidated statements of operations. Advances from Customers —The Company receives advances from customers associated with certain projects. In fiscal 2012, the Company entered into an agreement with the Mexican government to provide a turnkey security screening solution at various locations throughout the country. Associated with the agreement, the Company was provided an advance totaling $100 million. The Company is obligated to provide a guarantee until the advance has been amortized. As of June 30, 2016, $25.0 million of this advance remains outstanding and is included in Advances from customers. Environmental Contingencies —The Company is subject to various environmental laws. The Company's practice is to conduct appropriate environmental investigations at its manufacturing facilities in North America, Asia-Pacific, and Europe, and, to the extent practicable, on all new properties in order to identify, as of the date of such investigation, potential areas of environmental concern related to past and present activities or from nearby operations. In certain cases, the Company has conducted further environmental assessments consisting of soil and groundwater testing and other investigations deemed appropriate by independent environmental consultants. During one investigation at the Company's Hawthorne, California facility, the Company discovered soil and groundwater contamination that it believes was the result of unspecified on- and off-site releases occurring prior to the Company's occupancy. Historical usage of this site includes semiconductor and electronics manufacturing, dating back to the mid-1960s, as well as possible aircraft and related manufacturing dating to the early 1940s. Similar operations, including chemical manufacturing and storage, were conducted at neighboring sites throughout that period and into the 1990s. It is not presently known when the releases occurred or by whom they were caused, though Company records, in conjunction with data obtained from soil and groundwater surveys, support the Company's assertion that these releases are historical in nature, having occurred prior to the Company's occupancy. Further, the groundwater contamination is a known regional issue, not limited to the Company's premises or its immediate surroundings. The Company has filed all requisite reports with the appropriate environmental authorities and continues to cooperate with the local governing agency to develop a complete and accurate characterization of this site. Recent activities include the installation of groundwater monitoring wells, indoor air quality monitoring and additional soil and soil vapor studies. Results from these studies are being evaluated to determine the extent of the on-site releases as well as appropriate and cost-effective remedial action measures. Periodic groundwater monitoring is expected to continue until such time as the governing authority requests further action. The Company has not accrued for loss contingencies relating to the Hawthorne facility or any other environmental matters because it believes that, although unfavorable outcomes may be possible, they are not considered by the Company's management to be probable and reasonably estimable. If one or more of these environmental matters are resolved in a manner adverse to the Company, the impact on the Company's business, financial condition, results of operations and cash flow could be material. Indemnifications —In the normal course of business, the Company has agreed to indemnify certain parties with respect to certain matters. The Company has agreed to hold certain parties harmless against losses arising from a breach of representations, warranties or covenants, or intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its directors and certain of its officers. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. The Company has not recorded any liability for costs related to contingent indemnification obligations as of June 30, 2016. Legal Proceedings —Three shareholder derivative complaints (the "Derivative Actions") have been filed purportedly on behalf of the Company against the members of the Company's Board of Directors (as individual defendants). Hagan v. Chopra et al. was filed in the United States District Court for the Central District of California (the "Court") on April 15, 2014, and was subsequently consolidated by the Court with City of Irving Benefit Plan v. Chopra et al., which was filed on December 29, 2014. Kocen v. Chopra et al. was filed in the Delaware Court of Chancery on July 14, 2015. The Derivative Actions generally assert claims for breach of fiduciary duties and unjust enrichment against the individual defendants on behalf of the Company. Plaintiffs in the Derivative Actions seek unspecified damages, restitution, injunctive relief, attorneys' and experts' fees, costs, expenses, and other unspecified relief. Following a mediation and post-mediation settlement discussions, the parties to the Derivative Actions reached a settlement and have signed a settlement term sheet, which, if approved, would provide for the resolution of all pending claims in both the California and Delaware actions. The Company and the other defendants agreed to the settlement term sheet to avoid further expense, inconvenience, and the distraction and inherent risks of burdensome and protracted litigation. Neither the Company nor the individual defendants conceded any wrongdoing or liability, and continue to believe that they have meritorious defenses to all claims alleged in the Derivative Actions. The settlement is subject to approval by the Court and certain other conditions. The Company is involved in various other claims and legal proceedings arising in the ordinary course of business. In the Company's opinion after consultation with legal counsel, the ultimate disposition of such proceedings is not likely to have a material adverse effect on its business, financial condition, results of operations or cash flows. The Company has not accrued for loss contingencies relating to such matters because it believes that, although unfavorable outcomes in the proceedings may be 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 the Company, the impact on the Company's business, financial condition, results of operations and cash flow could be material.

RELATED-PARTY TRANSACTIONS
RELATED-PARTY TRANSACTIONS	11. RELATED-PARTY TRANSACTIONS In 1994, the Company, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India. The Company owns a 36% interest in the joint venture, the Company's Chairman and Chief Executive Officer owns a 10.5% interest, and the Company's Executive Vice President of OSI Solutions Business and Director owns a 4.5% ownership interest. The Company's initial investment was approximately $0.1 million. For each of the years ended June 30, 2015 and 2016, the Company's equity earnings in the joint venture were less than $0.1 million. There was no equity earnings in the joint venture recognized for the year ended June 30, 2014. The Company, its Chairman and Chief Executive Officer and the Company's Executive Vice President of OSI Solutions Business and Director collectively control less than 50% of the board of directors voting power in the joint venture. As a result, the Company accounts 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 the Company's 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 2014, 2015 and 2016 were approximately $5.2 million, $7.3 million and $9.1 million, respectively. Receivables from the joint venture were $2.7 million and $3.6 million as of June 30, 2015 and 2016, respectively. The Company has contracted with entities owned by its Chief Executive Officer and/or his family members to provide auto rental, printing, warehousing and consulting services. Such expenses for 2014 and 2016 were approximately $31,000 and $34,000, respectively; there were no expenses during 2015.

EMPLOYEE BENEFIT PLANS
EMPLOYEE BENEFIT PLANS	12. EMPLOYEE BENEFIT PLANS Employee Retirement Savings Plans The Company has various qualified employee retirement savings plans. Participants can contribute certain amounts to the plans and the Company matches a certain portion of employee contributions. The Company contributed approximately $4.1 million, $4.5 million and $4.6 million to the plans for the fiscal years ended June 30, 2014, 2015 and 2016, respectively. Deferred Compensation Plan The Company has 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. The Company 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 the Company and, also, vest completely upon the participant's disability or death while employed by the Company or immediately prior to a change of control. The Company made contributions of $0.6 million, $0.7 million and $0.6 million during fiscal year 2014, 2015 and 2016, respectively. As of June 30, 2016, the Company held assets of $21.3 million and liabilities of $16.0 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 The Company sponsors a number of qualified and nonqualified pension plans for its employees at certain locations. In accordance with accounting standards for employee pension and postretirement benefits, the Company fully recognizes the overfunded or underfunded status of each of its 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. The Company measures its 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 2015 and 2016, and a statement of the funded status as of June 30, 2015 and 2016 (in thousands): 2015 2016 Change in Benefit Obligation Benefit obligation at beginning of year $ $ Translation adjustment ) ) Service costs — Interest costs Curtailment — ) Actuarial (gain) loss Benefits paid ) ) ​ ​ ​ ​ ​ ​ ​ ​ Benefit obligation at end of year ​ ​ ​ ​ ​ ​ ​ ​ Change in Plan Assets Fair value of plan assets at beginning of year Translation adjustment ) ) Actual return on plan assets Company contributions Benefits paid ) ) ​ ​ ​ ​ ​ ​ ​ ​ Fair value of plan assets at end of year ​ ​ ​ ​ ​ ​ ​ ​ Funded status ) ) Unrecognized net actuarial loss — — ​ ​ ​ ​ ​ ​ ​ ​ Net amount recognized $ ) $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount recognized in consolidated balance sheets consists of: Investments $ $ Accrued pension liability ) ) Accumulated other comprehensive income The following table provides the net periodic benefit costs for each of the fiscal years ended June 30, (in thousands): 2014 2015 2016 Net Periodic Benefit Costs Service costs $ $ $ — Interest costs Expected return on plan assets ) ) ) Amortization of prior service costs Recognized actuarial loss ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net periodic benefit cost $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Plan Assumptions 2015 2016 Weighted average assumptions at year-end: Discount rate % % Expected return on plan assets % % 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. Plan Assets and Investment Policy Fiscal year ended June 30, 2015 Fiscal year ended June 30, 2016 Proportion of Fair Value Expected Rate of Return Proportion of Fair Value Expected Rate of Return Equity securities % % % % Debt securities % % % % Other % % % % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Combined % % % % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 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, 2016 (in thousands): Pension Benefits July 1, 2016 to June 30, 2017 $ July 1, 2017 to June 30, 2018 July 1, 2018 to June 30, 2019 July 1, 2019 to June 30, 2020 July 1, 2020 to June 30, 2021 July 1, 2021 to June 30, 2026 Company Contribution As of June 30, 2016, the Company's weighted average contribution rate is under 1% of pensionable salaries. If Company contributions continue at the current rate, the estimated total Company contributions for fiscal 2017 will be approximately $0.1 million.

Consolidation	Consolidation —The consolidated financial statements include the accounts of OSI Systems, Inc. and its wholly-owned and majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Investments in joint ventures over which the Company has significant influence but does not have voting control are accounted for using the equity method. Investments over which the Company does not have significant influence are accounted for using the cost method.
Pending acquisition	Pending Acquisition —On June 20, 2016, OSI Systems, Inc. and American Science and Engineering, Inc. signed a definitive agreement pursuant to which the Company will acquire AS&E for $37.00 in cash per share of common stock of AS&E for a total purchase price of approximately $269 million. The Company intends to fund the transaction with a combination of AS&E's cash on hand and money borrowed under its revolving credit facility. As of June 30, 2016, AS&E reported cash and cash equivalents of $74 million. The completion of the transaction is subject to the satisfaction of customary conditions, including, among others: (i) the requisite approval of AS&E's shareholders, (ii) the expiration or termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR Act") and (iii) the absence of any order or injunction issued by any court or governmental authority in the United States preventing the consummation of the transaction. The transaction is expected to close by December 31, 2016.
Use of Estimates	Use of Estimates —The preparation of financial statements in conformity with U.S. 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 the Company relate to contract revenue, profit and loss recognition, fair values of assets acquired and assumed in business combinations, market values for inventories reported at lower of cost or market, 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 differ from these estimates and could differ materially.
Reclassifications	Reclassifications —Certain reclassifications have been made to prior year amounts within the consolidated balance sheet to conform to the current year's presentation. The Company early adopted accounting standards update ("ASU") 2015-17, Balance Sheet Classification of Deferred Income Taxes, which amends the classification of deferred taxes. Deferred tax assets and liabilities will now be classified as non-current. Previously, the deferred income tax assets and liabilities had to be separated into current and non-current. The Company applied the ASU retrospectively, which resulted in reclassifications to the consolidated balance sheet as of June 30, 2015. In addition, unrelated to the adoption of ASU 2015-17, certain accounts were grouped differently than had been presented in the consolidated balance sheet as of June 30, 2015. The following table summarizes these reclassifications as follows (in thousands): Changes to Consolidated Balance Sheet as of June 30, 2015 As previously presented DR (CR) Reclassifications Pursuant to ASU 2015-17 Other Reclassifications Current DR (CR) Deferred income tax asset ) — Other assets Income tax payable ) — — Other accrued expenses and current liabilities ) ) ) Advances from customers—non-current ) — Deferred income tax liability ) ) Other long-term liabilities ) ) ) — — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net decrease to working capital ) — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net decrease to total assets ) — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
Cash Equivalents	Cash Equivalents —The Company considers all highly liquid investments purchased with maturities of approximately three months or less as of the acquisition date to be cash equivalents.
Accounts Receivable	Accounts Receivable —The Company monitors collections and payments from its customers and maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. Components of accounts receivable consisted of (in thousands): June 30, 2015 2016 Accounts receivables $ $ Less allowance for doubtful accounts ) ) ​ ​ ​ ​ ​ ​ ​ ​ Total $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
Inventories	Inventories —Inventories are generally stated at the lower of cost (first-in, first-out) or market. The Company writes down inventory for slow-moving and obsolete inventory based on assessments of future demands, market conditions and customers who may be experiencing financial difficulties. If these factors are less favorable than those projected, additional inventory write-downs may be required.
Property and Equipment	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 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 or if any indicators of impairment exist. Certain fixed assets related to the Company's turnkey security screening program in Mexico are not currently in use. As of June 30, 2016, the net value of these assets is approximately $15 million, which is included in property and equipment in the condensed consolidated balance sheet.
Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets	Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets —Goodwill represents the excess purchase price of net tangible and intangible assets acquired in business combinations over their estimated fair value. Goodwill is allocated to the Company's 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 the Company's second quarter and more often if there is an indicator of impairment. Intangible assets other than goodwill are amortized over their useful lives unless these lives are determined to be indefinite. The Company assesses qualitative factors of each of its 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. Such assessments indicated that it is not more likely than not that the fair value of each reporting unit is less than its carrying amount, including goodwill. Thus, the Company has determined that it is not necessary to proceed with the two-step goodwill impairment test. There was no goodwill impairment for each of three fiscal years ended June 30, 2016. The Company evaluates 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, the Company measures the impairment loss and records it based on the discounted estimate of future cash flows. In estimating future cash flows, the Company groups assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other asset groups. The Company's 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	Income Taxes —Deferred income taxes are provided for temporary differences between the financial statement and income tax basis of the Company's assets and liabilities, based on enacted tax rates. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Income tax accounting standards prescribe a two-step process for the financial statement measurement and recognition of a tax position taken or expected to be taken in a tax return. The first step involves the determination of whether it is more likely than not (greater than 50 percent likelihood) that a tax position will be sustained upon examination, based on the technical merits of the position. The second step requires that any tax position that meets the more-likely-than-not recognition threshold be measured and recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The income tax accounting standards also provide guidance on the accounting for related interest and penalties, financial statement classification and disclosure. The cumulative effect of applying these standards is to be reported as an adjustment to the opening balance of retained earnings in the period of adoption. See note 8 for additional information.
Fair Value of Financial Instruments	Fair Value of Financial Instruments —The Company's 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 the Company's 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 the Company. 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 whose 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, the Company's 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 our financial assets and liabilities as of June 30, 2015 and 2016 are categorized as follows (in thousands): June 30, 2015 June 30, 2016 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Equity securities $ $ $ — $ $ $ — — $ Insurance company contracts — — — — Interest rate contract — ) — ) — ) — ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total assets $ $ $ — $ $ $ $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities—Contingent payment obligations $ — $ — $ $ $ — $ — $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
Derivative Instruments and Hedging Activity	Derivative Instruments and Hedging Activity —The Company's 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 in the consolidated financial statements and are reclassified as net income when the hedge transaction settles.
Revenue Recognition	Revenue Recognition —The Company recognizes revenue from sales of products upon shipment when title and risk of loss passes, and when terms are fixed and collection is probable. 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. The portion of revenue for the sale attributable to installation is deferred and recognized when the installation service is provided. In an instance where terms of sale include subjective customer acceptance criteria, revenue is deferred until the Company has achieved the acceptance criteria. Concurrent with the revenue recognition, the Company accrues estimated product return reserves and warranty expenses. 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 recognized. Critical judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product under warranty. In instances where a contract calls for multiple deliverables and such deliverables qualify as separate units of accounting, the Company may recognize revenue based on the value of the respective deliverables identified in the underlying contract. 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 this 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. In the event that revenue recognition exceeds payments received from the customer, unbilled receivables are recorded. Revenues from out-of-warranty service maintenance contracts are recognized ratably over the term of such contracts. For services not derived from specific maintenance contracts, revenues are recognized as the services are performed. Deferred revenue for such services arises from payments received from customers for services not yet performed. On occasion, the Company receives advances from customers that are amortized against future customer payments pursuant to the underlying agreements. Such advances are classified in the condensed consolidated balance sheets as either a current or long-term liability depending on when the Company estimates the corresponding amortization to occur.
Freight	Freight —The Company records shipping and handling fees it charges to its customers as revenue and related costs as cost of goods sold.
Research and Development Costs	Research and Development Costs —Research and development costs are those costs related to the development of a new product, process or service, or significant improvement to an existing product, process or service. Such costs are charged to operations as incurred.
Stock-Based Compensation	Stock-Based Compensation —Stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the employee's requisite service period for all stock-based awards granted or modified. Certain restricted awards vest based on the achievement of pre-established performance criteria. The fair value of performance-based awards is estimated at the date of grant based upon the probability that the specified performance criteria will be met, adjusted for estimated forfeitures. Each quarter the Company updates the assessment of the probability that the specified performance criteria will be achieved and adjusts the estimate of the fair value of the performance-based awards if necessary. The Company amortizes the fair value of performance-based awards over the requisite service period for each separately vesting tranche of the award. See note 7 to the consolidated financial statements.
Impairment, Restructuring and Other Charges	Impairment, Restructuring and Other Charges —The Company accounts for certain charges related to restructuring activities, litigation, acquisition-related costs and other non-routine charges as Impairment, restructuring and other charges in the consolidated financial statements. See note 5 for additional information about these restructuring charges.
Credit Risk and Concentration	Credit Risk and Concentration —Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. The Company restricts investments in cash equivalents to financial institutions with high credit standing. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company's worldwide customer base. As of June 30, 2015 and 2016, no customer accounted for greater than 10% of accounts receivable. SAT accounted for 12% and 14% of revenues for the fiscal years ended June 30, 2015 and 2016, respectively. The Company performs ongoing credit evaluations of its customers' financial condition and maintains allowances for potential credit losses. The Company relies primarily on a vendor that provides key components to the Optoelectronics and Manufacturing division. 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.
Foreign Currency Translation	Foreign Currency Translation —The Company transacts business in various foreign currencies. In countries where the functional currency of the underlying operations has been determined to be the local country's currency, revenues and expenses of operations outside the United States are translated into United States dollars using average exchange rates while assets and liabilities of operations outside the United States are translated into United States dollars using period-end exchange rates. The effects of foreign currency translation adjustments are included in stockholders' equity as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. Transaction gains and losses, which were included in the Company's consolidated statement of operations, amounted to a gain (loss) of approximately $(1.8) million, $2.1 million and $(0.8) million for the fiscal years ended June 30, 2014, 2015 and 2016, respectively.
Business Combinations	Business Combinations —The Company allocates the fair value of purchase consideration to the tangible and intangible assets acquired, and liabilities assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is 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, and 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. During the measurement period, which is one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. During the year ended June 30, 2016, the Company acquired all of the outstanding shares of capital stock of a distributor and manufacturer of electronic components in the United Kingdom, a distributor and manufacturer of flex circuit and touch panel design products in California and a security equipment service company in Brazil. The combined purchase prices consisted of cash payments at closing of $17.8 million, holdbacks of $2.6 million for potential indemnity claims and $13.8 million for the fair value of contingent consideration. The indemnity holdbacks are payable in fiscal 2017, if not used for indemnification claims. The combined purchase prices were allocated to the fair values of the net tangible and intangible assets. The combined allocations of intangible assets consisted of $25.3 million of goodwill and $8.3 million of identifiable intangible assets, which was comprised of $1.2 million of technology, $6.0 million of customer relationships, $0.9 million of trademarks and trade names, and $0.2 million of non-compete covenants.
Earnings per Share	Earnings per Share —Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common stockholders by the sum of the weighted average number of common and dilutive potential common shares outstanding. Potential common shares consist of the shares issuable upon the exercise of stock options and restricted stock or units awards under the treasury stock method. During the fiscal years ending June 30, 2014 and 2015, respectively, the number of stock options and stock awards excluded from the calculation because they were antidilutive was de minimis. Stock option and stock awards to purchase 0.1 million shares of common stock for the fiscal year ending June 30, 2016 were excluded for the calculation because to do so would have been antidilutive. The following table sets forth the computation of basic and diluted earnings per share for the fiscal years ended June 30 (in thousands, except earnings per share data): 2014 2015 2016 Net income available to common stockholders $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding—basic Dilutive effect of equity awards ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding—diluted ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic earnings per share $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted earnings per share $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
Warranty provision	Warranty Provision —The Company offers its customers warranties on many of the products that it sells. These warranties typically provide for repairs and maintenance of the products if problems arise during a specified time period after original shipment. Concurrent with the sale of products, the Company records a provision for estimated warranty expenses with a corresponding increase in cost of goods sold. The Company periodically adjusts this provision based on historical experience and anticipated expenses. The Company charges actual expenses of repairs under warranty, including parts and labor, to this provision when incurred. The warranty provision is included in the Other accrued expenses and current liabilities in the consolidated balance sheets, whose activity for each of the three fiscal years ended June 30, 2016 is summarized in the following table (in thousands) Warranty provision as of June 30, 2013 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2014 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2015 $ Warranty claims provision Settlements made ) ​ ​ ​ ​ ​ Warranty provision as of June 30, 2016 $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
Recent Accounting Updates Not Yet Adopted	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 to depict 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 that reporting period. Earlier application is permitted only as of fiscal years beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company has not yet selected a transition method and is currently evaluating the impact this ASU may have on its financial condition and results of operations. In July 2015, FASB issued an ASU amending some of the guidance on subsequent measurement of inventory. This ASU affects companies that are using first-in, first-out or average cost, or any other methods besides last-in, first out or the retail inventory method. This ASU is effective for fiscal years beginning after December 15, 2016, including interim reporting periods within that reporting period. The amendments in this ASU should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its financial condition and results of operations. In September 2015, FASB issued an ASU simplifying the measurement-period adjustments for acquisitions. This update provides guidance on how an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. This amendment requires the acquirer to recognize adjustments to the provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined rather than retrospectively. This ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within that reporting period. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its financial condition and results of operations. 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, and interim periods within that reporting period. Early application is permitted. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its 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, and interim periods within that reporting period. Early application is permitted. The Company has not yet adopted this update and is currently evaluating the impact it may have on its financial condition and results of operations. In March 2016, the FASB issued an ASU relating to employee share-based payment accounting. This guidance simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within that reporting period. The Company has not yet adopted this ASU and is currently evaluating the impact it may have on its financial condition and results of operations.
