Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Nature of Operations Medtronic plc (Medtronic or the Company) is a global leader in medical technology – alleviating pain, restoring health, and extending life for millions of people around the world. The Company provides innovative products and therapies to serve hospitals, physicians, clinicians, and patients. Medtronic was founded in 1949 and is headquartered in Dublin, Ireland. Principles of Consolidation The consolidated financial statements include the accounts of Medtronic plc, its wholly-owned subsidiaries, entities for which the Company has a controlling financial interest, and variable interest entities for which the Company is the primary beneficiary. Intercompany transactions and balances have been fully eliminated in consolidation. Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. In connection with the preparation of the Form 10-K for the year ended April 28, 2017, the Company revised its consolidated balance sheet and consolidated statements of equity to properly present additional paid-in capital separate from retained earnings for the prior periods. The revision, which the Company determined is not material, had no impact on total equity, results of operations, or cash flows. Use of Estimates The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used when accounting for items such as income taxes, contingencies, and intangible asset and liability valuations. Actual results may or may not differ from those estimates. Fiscal Year-End The Company utilizes a 52/53-week fiscal year, ending the last Friday in April, for the presentation of its consolidated financial statements and related notes thereto at April 28, 2017 and April 29, 2016 and for each of the three fiscal years ended April 28, 2017 (fiscal year 2017), April 29, 2016 (fiscal year 2016), and April 24, 2015 (fiscal year 2015). Fiscal years 2017 and 2015 were 52-week years. Fiscal year 2016 was a 53-week year, with the additional week occurring in the first quarter. Cash Equivalents The Company considers highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value. Investments Investments in marketable equity securities and certain debt securities, which include corporate debt securities, government and agency securities, mortgage-backed securities, other asset-backed securities, debt funds, and auction rate securities, are classified and accounted for as available-for-sale. These investments are recorded at fair value in the consolidated balance sheets. The change in fair value for available-for-sale securities is recorded, net of taxes, as a component of accumulated other comprehensive loss on the consolidated balance sheets. Management determines the appropriate classification of its investments in debt and equity securities at the time of purchase and reevaluates such determinations at each balance sheet date. The classification of marketable securities as current or long-term is based on the nature of the securities and their availability for use in current operations consistent with how the Company manages its capital structure and liquidity. Investments in securities that are classified and accounted for as trading securities primarily include exchange-traded funds and are recorded at fair value on the consolidated balance sheets. Management has used trading securities when seeking to offset changes in liabilities related to equity and other market risks of certain deferred compensation arrangements. Certain of the Company’s investments in equity and other securities are long-term, strategic investments in companies that are in varied stages of development. These investments are included in other assets on the consolidated balance sheets. If an investment has no quoted market price, the Company accounts for these investments under the cost or the equity method of accounting, as appropriate. Certain of these investments are publicly traded companies and are therefore accounted for as available-for-sale. The valuation of equity and other securities accounted for under the cost method considers all available financial information related to the investee, including valuations based on recent third-party equity investments in the investee. If an unrealized loss for any investment is considered to be other-than-temporary, the loss is recognized in the consolidated statements of income in the period the determination is made. Equity securities accounted for under the equity method are initially recorded at the amount of the Company’s investment and are adjusted each period for the Company’s share of the investee’s income or loss and dividends paid. Equity securities accounted for under both the cost and equity methods are reviewed quarterly for changes in circumstance or the occurrence of events that suggest the Company’s investment may not be recoverable. See Note 6 for discussion of the gains and losses recognized on equity and other securities. Inventories Inventories are stated at the lower of cost or market, with cost determined on a first-in, first-out basis. The Company reduces the carrying value of inventories for those items that are potentially excess, obsolete or slow-moving based on changes in customer demand, technology developments or other economic factors. Property, Plant, and Equipment Property, plant, and equipment is stated at cost. Additions and improvements that extend the lives of the assets are capitalized, while expenditures for repairs and maintenance are expensed as incurred. The Company assesses property, plant, and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of property, plant, and equipment asset groupings may not be recoverable. The company utilizes the straight-line method of depreciation over the estimated useful lives of the various assets. The cost of interest that is incurred in connection with ongoing construction projects is capitalized using a weighted average interest rate. These costs are included in property, plant, and equipment and amortized over the useful life of the related asset. Goodwill and Intangible Assets Goodwill is the excess of the purchase price over the estimated fair value of net assets of acquired businesses. In accordance with U.S. GAAP, goodwill is not amortized. The Company assesses the impairment of goodwill annually in the third quarter and whenever an event occurs or circumstances change that would indicate the carrying amount may be impaired. Impairment testing for goodwill is done at a reporting unit level. An impairment loss is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. The estimated fair value is determined using a discounted future cash flow analysis. Intangible assets include patents, trademarks, tradenames, customer relationships, purchased technology, and in-process research and development (IPR&D). Intangible assets with a definite life are amortized on a straight-line basis with estimated useful lives ranging from three to 20 years. Intangible assets with a definite life are tested for impairment whenever events or changes in circumstances indicate that the carrying amount of an intangible asset (asset group) may not be recoverable. Indefinite-lived intangible assets are tested for impairment annually in the third quarter and whenever events or changes in circumstances indicate that the carrying amount may be impaired. Impairment is calculated as the excess of the asset’s carrying value over its fair value. Fair value is generally determined using a discounted future cash flow analysis. Acquired IPR&D represents the fair value assigned to those research and development (R&D) projects in development that were acquired in a business combination for which the related products have not received regulatory approval and have no alternative future use. IPR&D is capitalized at its fair value as an indefinite-lived intangible asset, and any development costs incurred after the acquisition are expensed as incurred. The fair value of IPR&D is determined by estimating the future cash flows of each R&D project or technology and discounting the net cash flows back to their present values. Upon achieving regulatory approval or commercial viability for the related technology or product, the indefinite-lived intangible asset is accounted for as a definite-lived asset and is amortized on a straight-line basis over the estimated useful life of the related technology or product. If the R&D project is not completed or the related R&D project is terminated or abandoned, the Company may have an impairment related to the IPR&D which is charged to expense. Contingent Consideration The Company recognizes contingent consideration at fair value at the date of acquisition based on the consideration expected to be transferred, estimated as the probability-weighted future cash flows, discounted back to present value. The discount rate used is determined at the time of measurement in accordance with accepted valuation methodologies. Contingent consideration is remeasured each reporting period with the change in fair value, including accretion for the passage of time, recognized as income or expense within acquisition-related items in the consolidated statements of income. Derivatives The Company recognizes all derivative financial instruments in its consolidated financial statements at fair value in accordance with authoritative guidance on derivatives and hedging, and presents assets and liabilities associated with its derivative financial instruments on a gross basis in the consolidated financial statements. For those derivative instruments that are designated and qualify as hedging instruments, the hedging instrument must be designated, based upon the exposure being hedged, as a fair value hedge, a cash flow hedge, or a hedge of a net investment in a foreign operation. See Note 9 for more information on the Company's derivative instruments and hedging programs. Fair Value Measurements The Company follows the authoritative guidance on fair value measurements and disclosures with respect to assets and liabilities that are measured at fair value on both a recurring and nonrecurring basis. Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability, based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels defined as follows:
• | Level 1 - Inputs are quoted prices in active markets for identical assets or liabilities.
• | Level 2 - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.
• | Level 3 - Inputs are unobservable for the asset or liability.
Financial assets that are classified as Level 1 securities include highly liquid government bonds within U.S. government and agency securities and marketable equity securities for which quoted market prices are available. In addition, the Company classifies currency forward contracts as Level 1 since they are valued using quoted market prices in active markets which have identical assets or liabilities. The valuation for most fixed maturity securities are classified as Level 2. Financial assets that are classified as Level 2 include corporate debt securities, government and agency securities, other asset-backed securities, debt funds, and mortgage-backed securities whose value is determined using inputs that are observable in the market or may be derived principally from, or corroborated by, observable market data such as pricing for similar securities, recently executed transactions, cash flow models with yield curves, and benchmark securities. In addition, interest rate swaps are included in Level 2 as the Company uses inputs other than quoted prices that are observable for the asset. The Level 2 derivative instruments are primarily valued using standard calculations and models that use readily observable market data as their basis. Financial assets are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies, or similar techniques, and at least one significant model assumption or input is unobservable. Financial assets that are classified as Level 3 financial assets include certain investment securities for which there is limited market activity such that the determination of fair value requires significant judgment or estimation, certain corporate debt securities and auction rate securities. With the exception of auction rate securities, these securities are valued using third-party pricing sources that incorporate transaction details such as contractual terms, maturity, timing, and amount of expected future cash flows, as well as assumptions about liquidity and credit valuation adjustments by market participants. The fair value of auction rate securities is estimated by the Company using a discounted cash flow model, which incorporates significant unobservable inputs. The significant unobservable inputs used in the fair value measurement of the Company’s auction rate securities are years to principal recovery and the illiquidity premium that is incorporated into the discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value of the securities. Certain investments for which the fair value is measured using the net asset value per share (or its equivalent) practical expedient are excluded from the fair value hierarchy. Financial assets for which the fair value is measured using the net asset value per share practical expedient include certain debt funds, equity and fixed income commingled trusts, and registered investment companies. Warranty Obligation The Company offers a warranty on various products. The Company estimates the costs that may be incurred under its warranties and records a liability in the amount of such costs at the time the product is sold. The amount of the reserve recorded is equal to the net costs to repair or otherwise satisfy the obligation. The Company includes the warranty obligation in other accrued expenses and other long-term liabilities on the consolidated balance sheets. Self-Insurance It is the Company’s policy to self-insure the majority of its insurable risks including medical and dental costs, disability coverage, physical loss to property, business interruptions, workers’ compensation, comprehensive general, and product liability. Insurance coverage is obtained for those risks required to be insured by law or contract. The Company uses claims data and historical experience, as applicable, to estimate liabilities associated with the exposures that the Company has self-insured. Based on historical loss trends, the Company believes that its self-insurance program accruals and its existing insurance coverage are adequate to cover future losses. Historical trends, however, may not be indicative of future losses. These losses could have a material adverse impact on the Company’s consolidated financial statements. Retirement Benefit Plan Assumptions The Company sponsors various retirement benefit plans, including defined benefit pension plans, post-retirement medical plans, defined contribution savings plans, and termination indemnity plans, covering substantially all U.S. employees and many employees outside the U.S. See Note 17 for assumptions used in determining pension and post-retirement benefit costs. The Company changed the methodology used to estimate the service and interest cost components of net periodic pension cost and net periodic post-retirement benefit cost for the Company’s pension and other post-retirement benefits, effective April 30, 2016. Prior to April 30, 2016, the Company estimated such cost components utilizing a single weighted-average discount rate derived from the market-observed yield curves of high-quality fixed income securities used to measure the pension benefit obligation and accumulated post-retirement benefit obligation. The current methodology utilizes a full yield curve approach in the estimation of these cost components by applying the specific spot rates along the yield curve to their underlying projected cash flows and provides a more precise measurement of service and interest costs by improving the correlation between projected cash flows and their corresponding spot rates. The change does not affect the measurement of the Company’s pension obligation or accumulated post-retirement benefit obligation. The Company accounted for this change prospectively as a change in accounting estimate. Revenue Recognition The Company sells its products through direct sales representatives and independent distributors. The Company recognizes revenue when title to the goods and risk of loss transfers to customers, which may be upon shipment or upon delivery to the customer site, based on the contract terms or legal requirements, provided there are no material remaining performance obligations required of the Company or any matters requiring customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, revenue is recognized upon shipment provided all revenue recognition criteria have been met. A portion of the Company’s revenue is generated from inventory maintained at hospitals or with field representatives. For these products, revenue is recognized at the time the product has been used or implanted. The Company recognizes estimated sales returns, discounts, and rebates as a reduction of sales in the same period revenue is recognized. Rebates are estimated based on sales terms, historical experience, and trend analysis. In estimating rebates, the Company considers the lag time between the point of sale and the payment of the rebate claim, contractual commitments, including stated rebate rates, and other relevant information. The Company adjusts reserves to reflect differences between estimated and actual experience, and records such adjustment as a reduction of sales in the period of adjustment. In certain circumstances, the Company enters into arrangements in which multiple deliverables are provided to customers. Under multiple deliverable arrangements, the Company recognizes revenue in accordance with the principles described above and allocates the revenue based on the relative selling price of each deliverable, which is based on vendor specific objective evidence. Shipping and Handling Shipping and handling costs not included in cost of products sold are included in selling, general, and administrative expense in the consolidated statements of income and were $370 million, $316 million, and $284 million in fiscal years 2017, 2016, and 2015, respectively. Research and Development Research and development costs are expensed when incurred. Research and development costs include costs of all basic research activities as well as other research, engineering, and technical effort required to develop a new product or service or make significant improvement to an existing product or manufacturing process. Research and development costs also include pre-approval regulatory and clinical trial expenses. Contingencies The Company records a liability in the consolidated financial statements for loss contingencies when a loss is known or considered probable and the amount may be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. Insurance recoveries related to potential claims are recognized up to the amount of the recorded liability when coverage is confirmed and the estimated recoveries are probable of payment. These recoveries are not netted against the related liabilities for financial statement presentation. Income Taxes The Company has deferred taxes that arise because of the different treatment of transactions for financial statement accounting and income tax accounting, known as temporary differences. The Company records the tax effect of these temporary differences as deferred tax assets and deferred tax liabilities. Deferred tax assets generally represent items that may be used as a tax deduction or credit in a tax return in future years for which the Company has already recorded the tax benefit in the consolidated statements of income. The Company establishes valuation allowances for deferred tax assets when the amount of expected future taxable income is not likely to support the use of the deduction or credit. Deferred tax liabilities generally represent tax expense recognized in the consolidated financial statements for which payment has been deferred or expense has already been taken as a deduction on the Company’s tax return but has not yet been recognized as an expense in the consolidated statements of income. Other Expense, Net Other expense, net includes royalty income and expense, realized equity security gains and losses, currency transaction and derivative gains and losses, impairment charges on equity securities, Puerto Rico excise tax, and U.S. medical device excise tax. Currency Translation Assets and liabilities of non-U.S. dollar functional currency entities are translated to U.S. dollars at period-end exchange rates, and the currency impacts arising from the translation of the assets and liabilities are recorded as a cumulative translation adjustment, a component of accumulated other comprehensive loss on the consolidated balance sheets. Elements of the consolidated statements of income are translated at the average monthly currency exchange rates in effect during the period. Currency transaction gains and losses are included in other expense, net in the consolidated statements of income. Stock-Based Compensation The Company measures stock-based compensation expense at the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is generally the vesting period. The amount of stock-based compensation expense recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company estimates pre-vesting forfeitures at the time of grant and revises those estimates in subsequent periods. The total expense recognized over the vesting period equals the fair value of awards that vest. New Accounting Standards Recently Adopted In April 2015, the Financial Accounting Standards Board (FASB) issued accounting guidance that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the related debt liability. Prior to this amendment, debt issuance costs were recognized as an asset in the balance sheet and did not offset the related debt liability. The Company retrospectively adopted this guidance in the first quarter of fiscal year 2017. Its adoption resulted in a reduction of both assets and liabilities of $138 million on the Company's consolidated balance sheet at April 29, 2016 as previously filed in the Company's Annual Report on Form 10-K for the year ended April 29, 2016. Not Yet Adopted In May 2014, the FASB issued amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The guidance requires an entity to recognize revenue in an amount that reflects the consideration to which an entity expects to be entitled in exchange for the transfer of goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This accounting guidance is effective for the Company beginning in the first quarter of fiscal year 2019, and may be applied either retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of the change recognized at the date of initial application (modified retrospective method). Early adoption is permitted. The Company intends to adopt this guidance under the modified retrospective method. The Company is continuing to evaluate the impact of the guidance and will continue to monitor any modifications, clarifications, and interpretations communicated by the FASB. In January 2016, the FASB issued guidance which requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The guidance also includes a simplified impairment assessment of equity investments without readily determinable fair values and presentation and disclosure changes. This accounting guidance is required for the Company to adopt beginning in the first quarter of fiscal year 2019. The Company is unable to estimate the impact of the future adoption of this standard on its financial statements as it will depend on the equity investments at the adoption date. In February 2016, the FASB issued guidance which requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet. The guidance is to be applied using a modified retrospective approach at the beginning of the earliest comparative period in the financial statements and is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is evaluating the impact of the lease guidance on the Company's consolidated financial statements and anticipates recording additional assets and corresponding liabilities on its consolidated balance sheet related to operating leases within its lease portfolio upon adoption of the guidance. In March 2016, the FASB issued guidance to simplify the accounting for share based payment transactions by requiring all excess tax benefits and deficiencies to be recognized in income tax expense or benefit in earnings; eliminating the requirement to classify the excess tax benefits and deficiencies as additional paid-in capital. Under the new guidance, an entity makes an accounting policy election to either estimate the expected forfeiture awards or account for forfeitures as they occur. This accounting guidance is effective for the Company beginning in the first quarter of fiscal year 2018. The Company recognized excess tax benefits of $92 million, $82 million and $81 million in excess tax benefits in additional paid-in capital in fiscal years 2017, 2016, and 2015, respectively. In October 2016, the FASB issued guidance that requires the tax effect of inter-entity transactions, other than sales of inventory, to be recognized when the transaction occurs. This would eliminate the exception under the current guidance in which the tax effects of inter-entity asset transactions are deferred until the transferred asset is sold to a third party or otherwise recovered through use. This accounting guidance is required for the Company to adopt beginning in the first quarter of fiscal year 2019. Early adoption is permitted. The Company is currently evaluating the impact of the guidance on the Company's consolidated financial statements.
