CY2017	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">New Accounting Pronouncements</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"> </font></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those years, under either full or modified retrospective adoption. During 2016, in preparation for the adoption of ASU 2014-09, we began a review of the various types of customer contract arrangements for each of our businesses. These reviews include 1) accumulating all customer contractual arrangements; 2) identifying individual performance obligations pursuant to each arrangement; 3) quantifying consideration under each arrangement; 4) allocating consideration among the identified performance obligations; and 5) determining the timing of revenue recognition pursuant to each arrangement. During 2017 we completed these contract reviews and have implemented revised accounting system processes in order to capture information required to be disclosed under ASU 2014-09. We will adopt this new guidance using the modified retrospective method on January 1, 2018. We have substantially completed our analysis of the new guidance and have not identified any material changes to the timing or amount of revenue to be recognized in future periods. The disclosures related to revenue recognition will be significantly expanded under ASU 2014-09, specifically around the quantitative and qualitative information about performance obligations, changes in contract assets and liabilities, and disaggregation of revenue. We continue to evaluate these requirements.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" to clarify the guidance on principal versus agent considerations. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing" to clarify the guidance on identifying performance obligations and the licensing implementation guidance. This ASU does not change the effective date or adoption method under ASU 2014-09, which is noted above.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Additionally, in May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients." This ASU addresses and amends several aspects of ASU 2014-09, but does not change the core principle of the guidance. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory” (Topic 330), which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. The ASU requires entities to compare the cost of inventory to one measure - net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and is to be applied prospectively with early adoption permitted. As a result of the adoption of this standard during the first quarter of 2017, there was no material impact on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, "Leases" (Topic 842) to increase comparability and transparency among different organizations. Organizations are required to recognize lease assets and lease liabilities on the balance sheet and disclose key information about the leasing arrangements and cash flows. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods, under a modified retrospective adoption with early adoption permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" as part of a simplification initiative. The update addresses and simplifies several aspects of accounting for share-based payment transactions. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted, and is to be applied using either modified retrospective, retrospective, or prospective transition method based on which amendment is being applied. Upon adoption of ASU 2016-09, we elected to change our accounting policy to account for forfeitures as they occur, using a modified retrospective method and determined that a cumulative-effect adjustment to retained earnings would be immaterial at transition during the first quarter of 2017. Amendments related to accounting for excess tax benefits have been adopted using a prospective transition method and there were no unrealized excess tax benefits prior to adoption that would require a modified retrospective transition method. Prospectively, excess tax benefits for share-based payments, if any, are now included in cash flows from operating activities rather than financing activities. The ASU also requires entities to classify as financing activities on the statement of cash flows, the cash paid to tax authorities when shares are withheld to satisfy the employer’s statutory income tax withholding obligation, with the application of this requirement to be applied retrospectively. As a result of share-based compensation that vested during 2017 and 2016, the impact to the Consolidated Statements of Cash Flows was </font><font style="font-family:Arial;font-size:10pt;">$0.8 million</font><font style="font-family:Arial;font-size:10pt;"> and </font><font style="font-family:Arial;font-size:10pt;">$1.7 million</font><font style="font-family:Arial;font-size:10pt;">, respectively, of tax remittances on equity based compensation as a financing activity.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses. ASU 2016-13, which has an effective date of the first quarter of fiscal 2022, also applies to employee benefit plan accounting. We are currently assessing the potential effects of these changes to our consolidated financial statements and employee benefit plan accounting.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" to reduce diversity in practice in classification of certain transactions in the statement of cash flows. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In November 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a modified retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Additionally, in November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash" to reduce diversity in the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for annual periods beginning after December 15, 2020, and interim periods within those annual periods, with early adoption permitted, under a prospective adoption. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In July 2017, the FASB issued ASU 2017-11, "Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception" to consider “down round” features when determining whether certain equity-linked financial instruments or embedded features are indexed to an entity’s own stock. Entities that present EPS under ASC 260 will recognize the effect of a down round feature in a freestanding equity-classified financial instrument only when it is triggered. The effect of triggering such a feature will be recognized as a dividend and a reduction to income available to common shareholders in basic EPS. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" to change how companies account for and disclose hedges. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements.</font></div></div>
