Recently Issued and Adopted Accounting Pronouncements and Regulatory Items	Recently Issued and Adopted Accounting Pronouncements and Regulatory Items New accounting guidance and regulatory items In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-09, Stock Compensation - Scope of Modification Accounting. This ASU provides guidance on which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The new standard is effective for fiscal years beginning after December 15, 2017 (i.e. a January 1, 2018 effective date). We believe the adoption will not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU provides requirements for presentation and disclosure of service and other components of net benefit cost on the financial statements. The new standard is effective for fiscal years beginning after December 15, 2017 (i.e. a January 1, 2018 effective date). We believe the adoption will not have a material impact on our consolidated financial statements other than potential disclosure requirements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU changes the subsequent measurement of goodwill impairment by eliminating Step 2 from the impairment test. Under the new guidance, an entity will measure impairment using the difference between the carrying amount and the fair value of the reporting unit. The new standard is effective for fiscal years beginning after December 15, 2019 (i.e. a January 1, 2020 effective date), with early adoption permitted for goodwill impairment tests with measurement dates after January 1, 2017. We believe the adoption will not have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations. This new ASU clarified the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new standard is effective for fiscal years beginning after December 15, 2017 (i.e. a January 1, 2018 effective date) and will be applied prospectively. At this time we do not intend on early adopting this ASU and will continue to assess the effects the amendments will have on future transactions of acquisitions or disposals. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. Under the new guidance, an entity will recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard is effective for fiscal years beginning after December 15, 2017 (i.e. a January 1, 2018 effective date), with early adoption permitted only in the first quarter of a fiscal year. Based on an initial assessment, we believe the adoption will not have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statements of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. This ASU addresses eight specific cash flow issues with the goal of reducing the existing diversity in practice in how certain cash receipts and cash payments are both presented and classified in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years (i.e. a January 1, 2018 effective date), with early adoption permitted. We have reviewed the eight cash flow issues and do not believe there will be any significant changes to FMC and our presentation of certain cash receipts and payments within our consolidated cash flow statement. In June 2016, the FASB issued No. ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments” ("ASU 2016-13"). ASU 2016-13 replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses. The update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The new standard is effective for fiscal years beginning after December 15, 2019 (i.e. a January 1, 2020 effective date), with early adoption permitted for fiscal years beginning after December 15, 2018. We are evaluating the effect the guidance will have on our consolidated financial statements. In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-02, Leases (Topic 842). Under the new guidance, lessees will be required to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e. a January 1, 2019 effective date). We are in the process of determining the transition plan and evaluating the effect the guidance will have on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Changes to the current guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The new standard is effective for fiscal years and interim periods beginning after December 15, 2017 (i.e. a January 1, 2018 effective date), and upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. We are evaluating the effect the guidance will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 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. This guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. We intend to adopt this standard for interim and annual periods beginning after December 15, 2017 (i.e. a January 1, 2018 effective date). The standard permits the use of either the retrospective or cumulative effect transition method. We expect to apply the modified retrospective adoption method. While, we are still evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures, in the fourth quarter of 2016, we performed an initial impact assessment by analyzing certain of our existing material revenue transactions and arrangements, and do not expect material changes to our current policies related to the timing of revenue recognition and the accounting for costs; however the standard will impact our disclosures by potentially requiring further disaggregation of revenue. Also, due to the recently announced agreement with DuPont, we expect to perform further impact assessments subsequent to the closing of the expected transaction. Recently adopted accounting guidance In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) ("ASU 2016-09"). ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The new standard was effective for annual reporting periods beginning after December 15, 2016, including interim periods within those years (i.e. a January 1, 2017 effective date). We adopted this standard prospectively beginning in 2017. The adoption impacted our recognition of excess tax benefit, which is recorded within provision for income taxes on the condensed consolidated statements of income. Additionally, the presentation of excess tax benefit on our condensed consolidated statements of cash flows was impacted as it is now shown within cash flows from operating activities. The excess tax benefit recognized within provision for income taxes for the three and six months ended June 30, 2017 was approximately $0.7 million and $1.3 million, respectively. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. This standard changes the criteria by which to measure inventory. Prior to the issuance of this new standard, inventory was measured at the lower of cost or market value. This required three separate data points in order to measure inventory. The three data points were cost, market with a ceiling of net realizable value and market with a floor of net realizable value less a normal profit margin. This amendment eliminates the two data points defining "market" and replaces them with one, net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This amendment does not impact inventory measured using last-in, first-out. This standard was effective for annual reporting periods beginning after December 15, 2016, (i.e. a January 1, 2017 effective date). We adopted this standard beginning in 2017. The adoption did not have an impact on the condensed consolidated financial statements.
