The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, and Regulation S-X. The information presented reflects the application of significant accounting policies described below.

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, as the response to the pandemic is developing and information is rapidly evolving. In recent months, a new strain of coronavirus (“COVID-19”) has spread to many countries around the world and the outbreak has been declared a pandemic by the World Health Organization. The U.S. Secretary of Health and Human Services has also declared a public health emergency in the U.S. in response to the outbreak. Considerable uncertainty still surrounds the COVID-19 virus and its potential effects, and the extent of and effectiveness of responses taken on international, national and local levels. Measures taken to limit the impact of COVID-19, including shelter-in-place orders, social distancing measures, travel bans and restrictions, and business and government shutdowns, have already created significant negative economic impacts on a global basis.

Due to these impacts and measures, the Company has experienced, and may continue to experience, significant and unpredictable reductions in the demand for its products as healthcare customers divert medical resources and priorities towards the treatment of COVID-19. In addition, the Company’s customers may delay, cancel, or redirect planned purchases in order to focus resources on COVID-19 or in response to economic disruption related to COVID-19. For example, beginning in mid-March 2020 and continuing into the first quarter of fiscal 2021, the Company experienced a significant decline in patient utilization in the U.S. and Europe, as healthcare systems diverted resources to meet the increasing demands of managing COVID-19. In addition, public health bodies have recommended delaying elective medical procedures during the COVID-19 pandemic, which may continue to negatively impact the usage of the Company’s products, including the number of Impella heart pump procedures. The Company may also experience delays in clinical trial enrollment or encounter interruption or delays in the operations of FDA or other regulatory authorities due to the COVID-19 pandemic, which may impact review and approval timelines. At the end of March 2020, the Company temporarily paused new enrollments in its active clinical trials in response to the COVID-19 response around the globe. The severity of the impact of the COVID-19 pandemic on its business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on its customers, all of which are uncertain and cannot be predicted.

While the ultimate health and economic impact of the COVID-19 pandemic is highly uncertain, the Company expects that its revenues, operating results and operating cash flows for the first quarter of fiscal 2021 will be materially adversely impacted. The Company currently expects to see sequential quarterly improvement in the remainder of fiscal 2021 as elective medical procedures are expected to be rescheduled. Further cancellations or delays could materially adversely impact the Company’s revenues and financial results. The Company cannot predict when elective medical procedures will resume or when symptomatic patients will return to the hospital or if its access to hospital sites will be limited, but the Company believes that the implementation of the cost reduction efforts that it has imposed, as discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

– COVID-19 Pandemic,” will help mitigate the impact that reduced revenues may have on its fiscal 2021 operating results. The Company intends to continue to monitor the situation and may extend these actions if necessary.

As of the date of issuance of these consolidated financial statements, the extent to which the COVID-19 pandemic may materially impact the Company's financial condition, liquidity, or results of operations is uncertain.

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, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, collectability of receivables, realizability of inventory, property and equipment, goodwill, intangible and other long-lived assets, other investments, accrued expenses, stock-based compensation, income taxes including deferred tax assets and liabilities, contingencies and litigation. Provisions for depreciation are based on their estimated useful lives using the straight-line method. Some of these estimates can be subjective and complex and, consequently, actual results may differ from these estimates under different assumptions or conditions.

The Company classifies any marketable security with an original maturity date of 90 days or less at the time of purchase as a cash equivalent. Cash equivalents are carried on the balance sheet at fair market value. The Company classifies any marketable security with a maturity date of greater than 90 days at the time of purchase as marketable securities and classifies marketable securities with a maturity date of greater than one year from the balance sheet date as long-term marketable securities.

The Company’s marketable securities, consisting of U.S. Treasury securities, government-back securities, corporate debt securities, and commercial paper, are classified as available-for-sale securities and, accordingly, are recorded at fair value. The difference between amortized cost and fair value is included in stockholders’ equity. Marketable securities that the Company has the positive intent and ability to hold to maturity are reported at amortized cost and classified as held-to-maturity marketable securities. If the Company does not have the intent and ability to hold a marketable security to maturity, it reports the investment as available-for-sale marketable securities. The Company includes unrealized gains and, to the extent deemed temporary, unrealized losses in stockholders’ equity. If any adjustment to fair value reflects a decline in the value of the investment, the Company considers available evidence to evaluate whether the decline is “other than temporary” and, if so, marks the marketable security to market through a charge reflected on the consolidated statements of operations.

The Company primarily sells its products to hospitals and distributors. No customer accounted for more than 10% of total revenues in fiscal years ended March 31, 2020, 2019 or 2018. No individual customer had an accounts receivable balance greater than 10% of total accounts receivable at March 31, 2020 and 2019.

Credit is extended based on an evaluation of a customer’s historical financial condition and generally collateral is not required. The Company’s history of credit losses has not been significant and the Company maintains an allowance for doubtful accounts based on its assessment of the collectability of accounts receivable. Accounts receivables are geographically dispersed, primarily throughout the U.S., as well as in Europe and other foreign countries where formal distributor agreements exist in certain countries. The Company's exposure to credit losses may increase if its customers are adversely affected by changes in healthcare laws, coverage, and reimbursement, economic pressures or uncertainty associated with local or global economic recessions, disruption associated with the current COVID-19 pandemic, or other customer-specific factors. Although the Company has historically not experienced significant credit losses, it is possible that there could be a material adverse impact from potential adjustments of the carrying amount of trade receivables as hospital's cash flows are impacted by their response to the COVID-19 pandemic.

Financial instruments which potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, marketable securities, short and long-term marketable securities and accounts receivable. Management mitigates credit risk by limiting the investment type and maturity to securities that preserve capital, maintain liquidity and have a high credit quality.

The Company’s financial instruments are comprised of cash and cash equivalents, derivative instruments, marketable securities, accounts receivable, accounts payable and contingent consideration. The carrying amounts of accounts receivable and accounts payable are considered reasonable estimates of their fair value, due to the short maturity of these investments.

The Company uses a foreign-exchange-related derivative instrument to manage its exposure related to changes in the exchange rate on its intercompany loan. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. The Company does not speculate using derivative instruments. The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. Changes in the fair value of the cross-currency swap designated as a hedging instrument that effectively offsets the variability of cash flows are reported in accumulated other comprehensive income. These amounts subsequently are reclassified into the consolidated income statement in the same period in which the related hedged item affects earnings. For more information, see “Note 4. Financial Instruments—Derivative Instruments.”

Inventories are stated at the lower of cost or market. Cost is based on the first in, first out method. The Company regularly reviews inventory quantities on hand and writes down to its net realizable value any inventory that it believes to be impaired. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. Once inventory is written down and a new cost basis is established, it is not written back up if demand increases.

Property and equipment is recorded at cost less accumulated depreciation. Land is carried at cost and is not depreciated. Depreciation is computed using the straight-line method based on estimated useful lives of three to five years for machinery and equipment, computer software, and furniture and fixtures. Building and building improvements are depreciated using the straight-line method over estimated useful lives of seven to thirty-three years. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful lives of the related assets. Expenditures for maintenance and repairs are expensed as incurred. Upon retirement or other disposition of assets, the costs and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is reflected in operating expenses.

Property and equipment is reviewed for impairment losses whenever events or changes in circumstances indicate the carrying amount may not be recoverable. An impairment loss would be recognized based on the amount by which the carrying value of the asset or asset group exceeds its fair value. Fair value is determined primarily using the estimated future cash flows associated with the asset or asset group under review discounted at a rate commensurate with the risk involved and other valuation techniques.

The Company periodically makes investments in medical device companies that focus on heart failure and heart pumps and other medical device technologies. For investments in convertible debt or preferred stock securities that do not have readily determinable market values, the Company measures these investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment. The Company monitors any events or changes in circumstances that may have a significant effect on the fair value of investments, either due to impairment or based on observable price changes, and makes any necessary adjustments.

On April 1, 2019, the Company adopted ASU 2016-02, “Leases.” This new guidance required that the Company’s lease commitments to be recognized as operating lease liabilities and right-of-use assets, which increased total assets and total liabilities that the Company reported on its consolidated balance sheet. For a discussion on the impact of this accounting policy adoption, including key accounting policies and elections, see “Note 9. Leases.”

Goodwill is recorded when consideration for an acquisition exceeds the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized. The Company evaluates goodwill for impairment at least annually at October 31, as well as whenever events or changes in circumstances suggest that the carrying amount may not be recoverable.

In applying the goodwill impairment test, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. Qualitative factors may include, but are not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for the Company’s products and services, regulatory and political developments, cost factors, and entity specific factors such as strategies and overall financial performance. If, after assessing these qualitative factors, the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying value, then performing a two-step impairment test is necessary. The first step is a comparison of the reporting unit’s fair value to its carrying value. If the reporting unit’s fair value exceeds its carrying value, no further procedures are required. However, if the reporting unit’s fair value is less than the carrying value, an impairment of goodwill may exist, requiring a second step to measure the amount of impairment loss. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge is recorded for the difference. The goodwill impairment test is performed at the reporting unit level by comparing the reporting unit’s carrying value, including goodwill, to the fair value of the reporting unit.

The Company performed a qualitative assessment during its annual impairment review for fiscal 2020 as of October 31, 2019 and concluded that it is more likely than not that the fair value of the Company’s single reporting unit is not less than its carrying amount. Therefore, the two-step goodwill impairment test for the reporting unit was not necessary in fiscal 2020.

In-process research and development, or IPR&D, assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that are acquired, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the IPR&D assets are considered indefinite-lived, they are tested for impairment on an annual basis on October 31, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying values. If and when development is complete, which generally occurs upon regulatory approval and the Company is able to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value. The Company performed its annual impairment review for fiscal 2020 as of October 31, 2019 and concluded that it was more likely than not that the fair value of the IPR&D assets is not less than its carrying value.

Contingent consideration represents potential milestones that the Company could pay additional consideration for a business acquisition and is recorded as a liability and is measured at fair value using a combination of (1) an income approach, based on various revenue and cost assumptions and applying a probability to each outcome and (2) a Monte-Carlo valuation model that simulates outcomes based on management estimates. With the income approach, probabilities were applied to each potential scenario and the resulting values were discounted using a rate that considers the weighted average cost of capital, the related projections, and the overall business. The Monte-Carlo valuation model simulates estimated future revenues during the earn out-period using management's best estimates. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones could result in a significantly higher or lower fair value of the contingent consideration liability. The fair value of the contingent consideration at each reporting date is updated by reflecting the changes in fair value reflected within research and development expenses in the Company’s consolidated statement of operations.

As part of the process of preparing its financial statements, the Company is required to estimate accrued expenses. This process includes identifying services that third parties have performed and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in its financial statements. Examples of estimated accrued expenses include estimates for certain payroll costs, such as bonuses and commissions; contract service fees, such as amounts due to clinical research organizations and investigators in conjunction with clinical trials; professional service fees, such as attorneys and accountants, and third-party expenses relating to marketing efforts associated with commercialization of the Company’s products. The dates in which certain services commence and end, the level of services performed on or before a given date and the cost of services is often subject to the Company’s judgment. The Company makes these judgments and estimates based upon known facts and circumstances.

On April 1, 2018 the Company adopted ASU 2014-09 (“Topic 606”), “Revenue from Contracts with Customers.’ For a discussion on the impact of this accounting policy adoption, including key accounting policies and elections, see “Note 3. Revenue Recognition.”

The Company generally provides a one-year warranty for certain products sold in which estimated contractual warranty obligations are recorded as an expense at the time of shipment. The Company’s products are subject to regulatory and quality standards. Future warranty costs are estimated based on historical product performance rates and related costs to repair given products. The accounting estimate related to product warranty expense involves judgment in determining future estimated warranty costs. Should actual performance rates or repair costs differ from estimates, revisions to the estimated warranty liability would be required.

Comprehensive income (loss) is comprised of net income, plus all changes in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, including any foreign currency translation adjustments. These changes in equity are recorded as adjustments to accumulated other comprehensive income (loss) in the Company’s consolidated balance sheet. The components of accumulated other comprehensive income (loss) consist of foreign currency translation adjustments and changes in unrealized gains (losses) on marketable securities and any unrealized gains or losses from derivative instruments. There were no reclassifications out of accumulated other comprehensive income (loss) during the fiscal years ended March 31, 2020, 2019 and 2018.

The functional currency of the Company’s foreign subsidiaries is their local currency. The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items in the Company’s consolidated statement of operations are translated at the average exchange rates prevailing during the period. The cumulative translation effect for subsidiaries using a functional currency other than the U.S. dollar is included in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity.

The Company’s intercompany accounts are denominated in the functional currency of the foreign subsidiary. Gains and losses resulting from the remeasurement of intercompany transactions that the Company considers to be of a long-term investment nature are recorded in accumulated other comprehensive income or loss as a separate component of stockholders’ equity, while gains and losses resulting from the remeasurement of intercompany transactions from those foreign subsidiaries for which the Company anticipates settlement in the foreseeable future are recorded in the consolidated statement of operations. The net foreign currency translation gains and losses recorded in the consolidated statements of operations for the fiscal years ended March 31, 2020, 2019 and 2018 were not significant.

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the fiscal year. Diluted net income per share is computed using the treasury stock method by dividing net income by the weighted average number of dilutive common shares outstanding during the fiscal year. Diluted shares outstanding is calculated by adding to the weighted average shares outstanding any potential dilutive securities outstanding for the fiscal year. Potential dilutive securities include stock options, restricted stock units, performance-based stock awards and shares to be purchased under the Company’s employee stock purchase plan. For the fiscal years ended March 31, 2020, 2019 and 2018, the Company’s basic and diluted net income per share were as follows (figures in tables are in thousands, except per share data):

	Fiscal Years Ended March 31,
Basic Net Income Per Share		2020		2019		2018
Net income	$	203,009	$	259,016	$	112,170

Weighted average shares - basic		45,179		44,911		44,153

Net income per share - basic	$	4.49	$	5.77	$	2.54

	Fiscal Years Ended March 31,
Diluted Net Income Per Share		2020		2019		2018
Net income	$	203,009	$	259,016	$	112,170

Weighted average shares - basic		45,179		44,911		44,153
Effect of dilutive securities		637		1,240		1,696
Weighted average shares - diluted		45,816		46,151		45,849

Net income per share - diluted	$	4.43	$	5.61	$	2.45

For the fiscal years ended March 31, 2020, 2019 and 2018, approximately 232,000, 64,000 and 155,000 shares of common stock underlying outstanding securities related to out-of-the-money stock options and performance-based awards where milestones were not met were not included in the computation of diluted earnings per share because their inclusion would be anti-dilutive.

The Company’s stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period.

The fair value of stock option grants is estimated using the Black-Scholes option pricing model. Use of the valuation model requires management to make certain assumptions with respect to selected model inputs. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a term consistent with the expected life of the stock options. Volatility assumptions are calculated based on historical volatility of the Company’s stock. The Company estimates the expected term of options based on historical exercise experience and estimates of future exercises of unexercised options. In addition, an expected dividend yield of zero is used in the option valuation model because the Company does not pay cash dividends and does not expect to pay any cash dividends in the foreseeable future. Forfeitures are recorded as they occur instead of estimating forfeitures that are expected to occur. An accounting policy change was made by the Company related to the recording of forfeitures in fiscal 2018 as a result of the adoption of ASU 2016-09, “Compensation – Stock Compensation (“Topic 718”): Improvements to Employee Share-Based Payment Accounting” discussed further below.

For awards with service conditions only, the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period. For awards with service and performance-based conditions, the Company recognizes stock-based compensation expense using the graded vesting method over the requisite service period. Estimates of stock-based compensation expense for an award with performance conditions are based on the probable outcome of the performance conditions. The cumulative effect of changes in the probability outcomes are recorded in the period in which the changes occur.

The Company’s provision for income taxes is comprised of a current and deferred provision. The current income tax provision is calculated as the estimated taxes payable or refundable on income tax returns for the current fiscal year. The deferred income tax provision is calculated for the estimated future income tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the temporary differences are expected to reverse.

Deferred income taxes are recognized for the tax consequences in future years as the differences between the tax bases of assets and liabilities and their financial reporting amounts at each fiscal year end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to impact taxable income.

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount that is more likely than not to be realized.

The Company recognizes and measures uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit at the largest amount that is more likely than not of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on an ongoing basis, when applicable. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, new information and technical insights, and changes in tax laws. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. Refer to “Note 12. Income Taxes” for further information related to the Tax Reform Act and its impact on the Company’s financial statements. When applicable, the Company accrues for the effects of uncertain tax positions and the related potential penalties and interest through income tax expense.

Effective April 1, 2019, the Company adopted the Financial Accounting Standards Board (“FASB”) standard update ASU 2016-02 “Leases,” which requires lessees to identify arrangements that should be accounted for as leases. Under this guidance, for lease arrangements exceeding a one-year term, a right-of-use asset and lease obligation is recorded by the lessee for all leases on the balance sheet, whether operating or financing, while the statement of operations includes lease expense for operating leases and amortization and interest expense for financing leases. ASU 2016-02 was adopted using a modified retrospective approach for all leases existing at or entered into after the April 1, 2019. Additional information and disclosures required by this new standard are contained in “Note 9. Leases.”

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326).” This guidance will require financial instruments to be measured at amortized cost, and accounts receivables to be presented at the net amount expected to be collected. The new model requires an entity to estimate credit losses based on historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments. ASU 2016-13 is effective for annual reporting periods beginning after December 31, 2019. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. ASU 2016-13 will become effective for the Company in fiscal 2021.

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350).” This guidance simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which required companies to estimate the implied fair value of goodwill and recognize an impairment charge by the amount in which the carrying value exceeds the implied fair value. Under the new guidance, if the carrying value of a reporting unit exceeds its fair value, a goodwill impairment charge will be recorded, even if the difference is attributable to the fair value of other assets in the reporting unit. ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. ASU 2017-04 will become effective for the Company in fiscal 2021.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820).” which modifies the disclosure requirements on fair value measurements. The Company has investments accounted for and disclosed under Topic 820 and will modify disclosures as applicable to conform with the new guidance. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019 and early adoption is permitted. The Company does not expect the adoption of this standard and the required disclosure changes to have a material impact on its consolidated financial statements. ASU 2018-13 will become effective for the Company in fiscal 2021.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740).” This amendment to the guidance on income taxes is intended to simplify the accounting for income taxes. The amendment eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. The amendment also clarifies existing guidance related to the evaluation of a step up in the tax basis of goodwill, and the effects of enacted changes in tax laws or rates in the effective tax rate computation, among other clarifications. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. ASU 2019-12 will become effective for the Company in fiscal 2022.

In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815),” an amendment clarifying the interaction between accounting standards related to equity securities, equity method investments, and certain derivative instruments. The guidance is effective for fiscal years beginning after December 15, 2020. ASU 2020-01 will become effective for the Company in fiscal 2022.
