Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2017-09, "Scope of Modification Accounting." ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will allow companies to make certain changes to awards, such as vesting conditions, without accounting for them as modifications. It does not change the accounting for modifications. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. We early adopted ASU 2017-09 during the second quarter of 2017, which has not affected our condensed consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." ASU 2017-07 will change how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost, which is comprised of several components, in the income statement. Under ASU 2017-07, employers will present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period, and will be the only costs eligible for capitalization. Employers will present the other components separately from the line item(s) that includes the service cost outside of the subtotal of Income from operations. ASU 2017-07 is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. In several foreign locations, we are statutorily required to provide a lump sum severance or termination indemnity to our employees and are currently evaluating the applicability of ASU 2017-07 to our situation. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment." ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 will provide a more stream-lined approach to evaluating future goodwill impairment and we early adopted on January 1, 2017 on a prospective basis as a change in accounting principle. There was no impact of ASU 2017-04 on our consolidated financial statements because a goodwill impairment has not occurred after January 1, 2017. In January 2017, the FASB issued ASU 2017-01, "Clarifying the Definition of a Business." ASU 2017-01 changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. If substantially all of the fair value is concentrated in a single asset or a group of similar assets, the acquired set is not a business. If this is not met, the entity then evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. Determining whether a set constitutes a business is critical because the accounting for a business combination differs significantly from that of an asset acquisition. We early adopted ASU 2017-01 on January 1, 2017 on a prospective basis, which has not had a material impact to our condensed consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, "Restricted Cash." ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 will be applied retrospectively and is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. We do not expect ASU 2016-18 to have a material impact to our financial statements and will only impact our statement of cash flows presentations. In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory." ASU 2016-16 requires immediate recognition of income tax consequences of intercompany asset transfers, other than inventory transfers. Existing GAAP prohibits recognition of income tax consequences of intercompany asset transfers whereby the seller defers any net tax effect and the buyer is prohibited from recognizing a deferred tax asset on the difference between the newly created tax basis of the asset in its tax jurisdiction and its financial statement carrying amount as reported in the consolidated financial statements. ASU 2016-16 specifically excludes from its scope intercompany inventory transfers whereby the recognition of tax consequences will take place when the inventory is sold to third parties. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. ASU 2016-16 should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We are currently evaluating the effect ASU 2016-16 will have on our consolidated financial statements. In August 2016, FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the effect ASU 2016-15 will have on our consolidated statements of cash flows. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments." ASU 2016-13 will replace the current incurred loss approach with an expected loss model for instruments measured at amortized cost and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount under the current other-than-temporary impairment model. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for all entities for annual periods beginning after December 15, 2018, and interim periods therein. We are currently evaluating the effect ASU 2016-13 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also allows an employer to repurchase more of an employee’s shares than permitted today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. We adopted ASU 2016-09 prospectively as a change in accounting principle on January 1, 2017, and made a policy election to account for forfeitures as they occur. As a result of adopting ASU 2016-09 as of January 1, 2017, the cumulative effect of the change on Retained earnings decreased by $0.3 million, and increased Additional paid-in capital and Deferred tax assets by $0.4 million and $0.1 million, respectively, in the Condensed Consolidated Balance Sheet. In March 2016, the FASB issued ASU 2016-07, "Simplifying the Transition to the Equity Method of Accounting," which eliminates the requirement to retrospectively apply the equity method in previous periods when an investor initially obtains significant influence over an investee. Under current guidance, an investor that does not consolidate an investment and initially accounts for it under a method other than the equity method is required to retrospectively apply the equity method in prior periods in which it held the investment when it subsequently obtained significant influence. We adopted ASU 2016-07 on January 1, 2017 on a prospective basis, which currently has not affected our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases," which will require, among other items, lease accounting to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. We do not plan to early adopt. ASU 2016-02 will be adopted on a modified retrospective basis, with elective reliefs, which requires application of ASU 2016-02 for all periods presented. We are currently gathering, documenting and analyzing lease agreements related to this ASU and anticipate material additions to the balance sheet for right-of-use assets, offset by the associated liabilities. In January 2016, the FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." Amendments under ASU 2016-01, among other items, require that all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. There will no longer be an available-for-sale classification, for which changes in fair value are reported in other comprehensive income, for equity securities with readily determinable fair values. For equity investments without readily determinable fair values, the cost method is also eliminated. However, entities will be able to elect to record equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Changes in the basis of these equity investments will be reported in current earnings. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For equity securities that would be affected by ASU 2016-01, see the available-for-sale investments table in Note 3 to the condensed consolidated financial statements, which primarily consists of our investment in Sartorius AG preferred shares. In addition per Note 3, we own ordinary voting stock of Sartorius AG and account for this investment using the cost method and we expect that the impact of adoption may be material to our consolidated statement of income. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost, net realizable value (NRV), or NRV less a normal profit margin. An entity uses current replacement cost provided that it is not above NRV (i.e., the ceiling) or below NRV less an “approximately normal profit margin” (i.e., the floor). ASU 2015-11 eliminates this analysis and requires entities to measure most inventory “at the lower of cost and NRV.” We prospectively adopted ASU 2015-11 as a change in accounting principle on January 1, 2017, which did not have a material impact on our condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. In August 2015, the FASB issued ASU 2015-14 to defer the effective date for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted as of the original effective date in ASU 2014-09, which is annual reporting periods beginning after December 15, 2016, however, we will not early adopt. In December 2016, the FASB issued ASU 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers" which affect narrow aspects of the guidance issued in ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, "Narrow-Scope Improvements and Practical Expedients," which amends and clarifies certain aspects in ASU 2014-09 that include collectiblity, presentation of sales and other taxes collected from customers, noncash consideration, contract modifications and completed contracts at transition. In April 2016, the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing," which amends the guidance in ASU 2014-09 on accounting for licenses of intellectual property and identifying performance obligations. In March 2016, the FASB issued ASU 2016-08, "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which amends the principal versus agent guidance in ASU 2014-09. The standards are to be applied retrospectively and permit the use of either the retrospective or cumulative effect transition method. We will use the cumulative effect transition method once we adopt ASUs 2014-09, 2016-20, 2016-12, 2016-10 and 2016-08 on January 1, 2018. We have completed revenue recognition diagnostic surveys across all regions in our decentralized sales contracting process, which is based on local country commercial regulations and practices. We have substantially completed our reviews of individual contracts to identify performance obligations under these ASU’s, as compared with the deliverables and separate units of accounting previously identified under current U.S. GAAP. To date, we have not identified any material changes in the timing of revenue recognition that could result in a significant transition adjustment upon our adoption of the new accounting standard on January 1, 2018; however, we have not yet completed our determination of the effect that these ASU’s will have on our consolidated financial statements and related disclosures.

In March 2017, the FASB issued ASU 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." ASU 2017-07 will change how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost, which is comprised of several components, in the income statement. Under ASU 2017-07, employers will present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period, and will be the only costs eligible for

capitalization. Employers will present the other components separately from the line item(s) that includes the service cost outside of the subtotal of Income from operations. ASU 2017-07 is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. In several foreign locations, we are statutorily required to provide a lump sum severance or termination indemnity to our employees and are currently evaluating the applicability of ASU 2017-07 to our situation.

In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment." ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 will provide a more stream-lined approach to evaluating future goodwill impairment and we early adopted on January 1, 2017 on a prospective basis as a change in accounting principle. There was no impact of ASU 2017-04 on our consolidated financial statements because a goodwill impairment has not occurred after January 1, 2017.

As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 will be applied retrospectively and is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. We do not expect ASU 2016-18 to have a material impact to our financial statements and will only impact our statement of cash flows presentations.

In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory." ASU 2016-16 requires immediate recognition of income tax consequences of intercompany asset transfers, other than inventory transfers.
