Accounting Policies [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	NOTE M – NEW ACCOUNTING PRONOUNCEMENTS From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, we evaluate the pronouncements to determine the potential effects of adoption on our condensed consolidated financial statements. Standards Implemented since December 31, 2016 ASC Update No. 2016-09 In March 2016, the FASB issued ASC Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The purpose of Update No. 2016-09 is to simplify accounting for share-based payment transactions, such as, the accounting for income taxes, statutory tax withholding requirements, forfeitures and statement of cash flow presentation. Update No. 2016-09 was effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods. We adopted Update No. 2016-09 prospectively in the first quarter of 2017 and, as such, no prior periods were adjusted. We previously recorded income tax benefits or deficiencies to additional paid-in capital; however, Update No. 2016-09 requires that all tax benefits or deficiencies be recorded to the provision for income taxes. In the first quarter of 2017, we recorded an income tax benefit of $28 million, which we expect represents the majority of excess tax benefits in 2017 due to the annual vesting of our awards during the first quarter. The actual impact to future periods will depend on the price of our stock, number of stock options exercised and other factors that are difficult to predict. In the first quarter of 2017, a cumulative effect adjustment of $76 million was recorded to retained earnings upon adoption for windfall tax benefits not previously recognized. ASC Update No. 2016-17 In October 2016, the FASB issued ASC Update No. 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control. The purpose of Update No. 2016-17 is to amend the consolidation guidance from Update No. 2015-02 on how a reporting entity that is the single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The amendment requires that a single decision maker include those indirect interests held through related parties that are under common control with the single decision maker on a proportionate basis consistent with indirect interests held through other related parties. Update No. 2016-17 was effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods. We adopted Update No. 2016-17 in the first quarter of 2017. The adoption of Update No. 2016-17 did not have a material impact on our financial position or results of operations. ASC Update No. 2016-19 In December 2016, the FASB issued ASC Update No. 2016-19, Technical Corrections and Improvements. The purpose of Update No. 2016-19 is to clarify or correct unintended applications of guidance that affects a wide variety of topics in the ASC. Most of the amendments in this Update did not require transition guidance and were effective immediately. Six amendments in this update clarified guidance or corrected references in the ASC and were effective for annual periods beginning after December 15, 2016, including interim periods within these annual periods. We adopted these amendments in the first quarter of 2017. The adoption of Update No. 2016-19 did not have a material impact on our financial position or results of operations. ASC Update No. 2017-04 In January 2017, the FASB issued ASC Update No. 2017-04, Intangibles - Goodwill and Other Topics (Topic 350): Simplifying the Test for Goodwill Impairment. The purpose of Update No. 2017-04 is to reduce the cost and complexity of evaluating goodwill for impairment. It eliminates the need for entities to calculate the impaired fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under this amendment, an entity will perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value. We elected to early adopt Update No. 2017-04 prospectively in the first quarter of 2017. The adoption of Update No. 2017-04 did not have a material impact on our financial position or results of operations. Standards to be Implemented ASC Update No. 2014-09 In May 2014, the FASB issued ASC Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which has been subsequently updated. The purpose of Update No. 2014-09 is to provide enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies using U.S. GAAP and International Financial Reporting Standards. The core principle requires entities to recognize revenue in a manner that depicts the transfer of goods or services to customers in amounts that reflect the consideration an entity expects to be entitled to in exchange for those goods or services. FASB ASC Topic 606, as amended, becomes effective for annual periods beginning after December 15, 2017, at which point we plan to adopt the standard. We currently plan to adopt the standard using the “modified retrospective method.” Under that method, we will apply the rules to contracts that are not completed as of January 1, 2018, and recognize the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings. We have reached conclusions on our key accounting assessments related to the standard and are finalizing our accounting policies. Based on our initial assessment, we believe the timing of revenue recognition for our primary revenue stream, single-use medical device sales, will not materially change. We are still finalizing our accounting policies related to variable consideration and assessing disclosure requirements. Upon adopting FASB ASC Topic 606, we will provide additional disclosures in the notes to the consolidated financial statements, specifically related to disaggregated revenue, contract balances and performance obligations. In 2017, we are implementing new internal controls as part of our efforts to adopt the new revenue recognition standard. These internal controls include providing global training to our finance team and holding regular meetings with management and the Audit Committee to review and approve key decisions. Upon adoption, we expect to implement new internal controls related to our accounting policies and procedures. We will require new internal controls to address risks associated with applying the five-step model, specifically related to judgments made in connection to variable consideration and applying the constraint. Additionally, we will establish monitoring controls to identify new sales arrangements and changes in our business environment that could impact our current accounting assessment. During the second half of 2017, we expect to finalize our impact assessment and redesign impacted processes, policies and controls. ASC Update No. 2016-01 In January 2016, the FASB issued ASC Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The purpose of Update No. 2016-01 is to improve financial reporting for financial instruments by reducing the number of items recorded to other comprehensive income. It requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value with changes recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. It simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. It also requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset and liability. Update No. 2016-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early application of certain provisions is permitted. We are unable to determine the effect that the adoption will have on our financial position and results of operations, as it will depend on the equity investments at the adoption date and their future performance. ASC Update No. 2016-02 In February 2016, the FASB issued ASC Update No. 2016-02, Leases (Topic 842). The purpose of Update No. 2016-02 is to increase the transparency and comparability among organizations by recognizing lease asset and lease liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. Update No. 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those annual. Early application is permitted. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. ASC Update No. 2016-13 In June 2016, the FASB issued ASC Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The purpose of Update No. 2016-13 is to replace the current incurred loss impairment methodology for financial assets measured at amortized cost with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information, including forecasted information, to develop credit loss estimates. Update No. 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early application is permitted for annual periods beginning after December 15, 2018. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. ASC Update No. 2016-15 In August 2016, the FASB issued ASC Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The purpose of Update No. 2016-15 is to reduce the diversity in practice in presentation and classification of the following items within the statement of cash flows: debt prepayments, or debt extinguishment costs, settlement of zero coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investments and beneficial interests in securitization transactions. It also addresses classification of transactions that have characteristics of more than one class of cash flows. Update No. 2016-15 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted, including application in an interim period. We are in the process of determining the effect that the adoption will have on our consolidated statements of cash flows. ASC Update No. 2016-16 In October 2016, the FASB issued ASC Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The purpose of Update No. 2016-16 is to allow an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, as opposed to waiting until the asset is sold to a third party, or impaired. Update No. 2016-16 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early application is permitted as of the beginning of an annual period for which financial statements have not been issued or made available for issuance. We are in the process of determining the effect that the adoption will have on our financial position and results of operations. ASC Update No. 2016-18 In November 2016, the FASB issued ASC Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The purpose of Update No. 2016-18 is to clarify guidance and presentation related to restricted cash in the statement of cash flows as well as increased disclosure requirements. It requires beginning-of-period and end-of-period total amounts shown on the statement of cash flows to include cash and cash equivalents as well as restricted cash and restricted cash equivalents. Update No. 2016-18 is effective for annual periods beginning after December 15, 2017, including interim reporting periods within those annual periods. Early application is permitted. We are in the process of determining the effect the adoption will have on our consolidated statements of cash flows. ASC Update No. 2017-01 In January 2017, the FASB issued ASC Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The purpose of Update No. 2017-01 is to change the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. Update No. 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual or interim period for which financial statements have not been issued or made available for issuance. The adoption of Update No. 2017-01 is not expected to have a material impact on our financial position or results of operations. ASC Update No. 2017-09 In May 2017, the FASB issued ASC Update No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. The purpose of Update No. 2017-09 is to provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Update No. 2017-09 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early application is permitted as of the beginning of an annual or interim period for which financial statements have not been issued or made available for issuance. The adoption of Update No. 2017-09 is not expected to have a material impact on our financial position or results of operations. ASC Update No. 2017-10 In May 2017, the FASB issued ASC Update No. 2017-10, Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services (a consensus of the FASB Emerging Issues Task Force). The purpose of Update No. 2017-10 is to address the diversity in practice as to how an operating entity determines the customer of the operation services in a service concession agreement. Update No. 2017-10 is effective the same time as FASB ASC Topic 606 and requires the same transition method elected for FASB ASC Topic 606. The adoption of Update No. 2017-10 is not expected to have a material impact on our financial position or results of operations. No other new accounting pronouncements, issued or effective, during the period had, or are expected to have, a material impact on our condensed consolidated financial statements.

NOTE M – NEW ACCOUNTING PRONOUNCEMENTS

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, we evaluate the pronouncements to determine the potential effects of adoption on our condensed consolidated financial statements.
