In addition, we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws as well as export controls and economic sanction laws. POLYONE CORPORATION 35 Description Judgments and Uncertainties Effect if Actual Results Differ from Assumptions Goodwill and Other, and test goodwill for impairment at least annually, absent a triggering event that would warrant an impairment assessment. The number of anti-dilutive options and awards was 0.4 million, 0.3 million and 1.2 million at December 31, 2014, 2013 and 2012, respectively.

In addition, we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws as well as export controls and economic sanction laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti- bribery laws may conflict with local customs and practices. The number of anti-dilutive options and awards was 0.3 million, 1.2 million and 0.5 million at December 31, 2013, 2012 and 2011, respectively.

The description set forth on pages 33-35 highlights the key financial results that were used in determining payouts to our Named Executive Officers under our 2015 Annual Incentive Program. ● Amended Long-Term Incentive Plan: We used Adjusted Earnings Per Share as the performance measure for our 2013 – 2015 Amended Long-Term Incentive Plan cash-settled performance units in order to drive improvements in shareholder value. However, we disclose such goals in future proxy statements once 30% 35% 35% 2015 Long-Term Incentive Plan Vehicles and Weighting Cash-Settled Performance Units Stock Appreciation Rights (SARs) Restricted Stock Units (RSUs) COMPENSATION DISCUSSION AND ANALYSIS 37 the applicable performance periods have ended as part of our discussion and analysis about the amounts earned by the Named Executive Officers under these awards. The areas we considered in determining that our compensation programs do not pose a material risk to PolyOne included our: Compensation Philosophy Payout Curves Clawback Policy Compensation Plan Design Weightings of Incentive Plan Measures Anti-Hedging/Anti-Pledging Policies Balanced Pay Mix Compensation Plan Governance and Oversight Stock Ownership Requirements Timing on Incentive Payouts Selection of Performance Measures Pay-for-Performance Validation As a result of the assessment, the Compensation Committee concluded that our compensation structures are appropriate and no material risks were identified.
