Trinseo S.A. (NYSE:TSE) Files An 8-K Submission of Matters to a Vote of Security Holders
Item 5.07Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers;

Compensatory Arrangements of Certain Officers.

(e)

On September 14, 2018, both Timothy Stedman and Hayati Yarkadas, each a Senior Vice President and Business President, were granted an equity retention award approved by the compensation committee of the board of directors of Trinseo S.A., a public limited liability company (sociétéanonyme) existing under the laws of Luxembourg (the “Company”). The equity retention award for each executive has a grant value of $1.3 million and consists of 50% performance award stock units (“PSUs”) and 50% restricted stock units (“RSUs”).

The RSUs will vest in full on the third anniversary of the grant date, generally subject to the executive’s continued employment with the Company. The PSUs will vest on the third anniversary of the grant date, subject generally to the executive’s continued employment and to the Company’s relative total shareholder return (“TSR”) performance, assuming the reinvestment of dividends, against the performance of 49 other chemical companies with shares traded on a major U.S. stock exchange and that have a market capitalization exceeding $500 million dollars at the time the award is granted. The threshold, target and maximum payout, which represents the 25th, 50th, and 75th percentile of TSR performance relative to peers, would be 50%, 50%, and 200% of the PSU award’s target amount, respectively. The number of PSUs ultimately vested will be interpolated between the 25th and 50th percentiles and between the 50th and 75th percentiles. Regardless of the foregoing targets, vesting of the PSUs is capped at 50% of target if the Company’s TSR is negative for the three-year performance period. Additionally, the total value of the awards delivered at vesting is capped at three times the target shares multiplied by the grant date share price. Because the Company assumes reinvestment of dividends, dividend equivalents accrue during the performance period. However, dividend equivalents will be paid only if, and to the extent, the PSUs vest.

The foregoing is a description of the executives’ equity retention award and does not purport to be a complete description of all the terms set forth in the applicable award agreements and, therefore, is qualified in its entirety by reference to Exhibits 10.1 and 10.2 incorporated into this Current Report.
