Accounting Policies [Abstract]
Basis Of Presentation	Note 1 — BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with Form 10-Q instructions and in the opinion of management contain all adjustments, consisting of normal recurring accruals, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. These interim financial statements should be read in conjunction with the financial statements and accompanying notes included in the annual report on Form 10-K for the year ended December 31, 2015 of PolyOne Corporation. When used in this quarterly report on Form 10-Q, the terms “we,” “us,” “our”, "PolyOne" and the “Company” mean PolyOne Corporation and its consolidated subsidiaries. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results that may be attained in subsequent periods or for the year ending December 31, 2016. Accounting Standards Not Yet Adopted In March 2016, the FASB issued Accounting Standards Update 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09), which simplifies the the accounting for share-based payment transactions. This update requires that excess tax benefits and tax deficiencies will be recognized as income tax expense or benefit in the Consolidated Statements of Income rather than additional paid-in capital. Additionally, the excess tax benefits will be classified along with other income tax cash flows as an operating activity, rather than a financing activity, on the Statement of Cash Flows. Further, the update allows an entity to make a policy election to recognize forfeitures as they occur or estimate the number of awards expected to be forfeited. ASU 2016-09 is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively, with certain cumulative effect adjustments. Early adoption is permitted. We do not expect this standard to have a material impact on our Consolidated Financial Statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, "Leases (Topic 842)" (ASU 2016-02), which requires a lessee to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases with a lease term of more than twelve months. Leases will continue to be classified as either financing or operating, with classification affecting the recognition, measurement and presentation of expenses and cash flows arising from a lease. The Company will adopt ASU 2016-02 no later than the required date of January 1, 2019. We are currently assessing the impact this standard will have on our Consolidated Financial Statements. In July 2015, the FASB issued Accounting Standards Update 2015-11, "Inventory (Topic 300): Simplifying the Measurement of Inventory" (ASU 2015-11), which applies to inventory measured using first-in, first out (FIFO) or average cost. This update requires that an entity should measure inventory that is within scope at the lower of cost and net realizable value, which is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This update is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. We do not expect this standard to have a material impact on our Consolidated Financial Statements. In May 2014, the FASB issued Auditing Standards Update 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09). Under this standard, a company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard implements a five-step process for customer contract revenue recognition that focuses on transfer of control. The Company will adopt ASU 2014-09 no later than the required date of January 1, 2018. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We are currently assessing the impact this standard will have on our Consolidated Financial Statements as well as the method by which we will adopt the new standard.
