(b) On April 23, 2018, Cabot Corporation announced that Eduardo E. Cordeiro, Executive Vice President and Chief Financial Officer, and President of the Americas Region of Cabot, will retire from Cabot at the end of 2018. He will step down from these roles with the Company effective May 15, 2018. Mr. Cordeiro will remain with Cabot in an advisory capacity through the end of the year to assist in a smooth transition.
(c) Effective May 15, 2018, Erica McLaughlin, age 41, will become Senior Vice President and Chief Financial Officer of the Company. Ms. McLaughlin joined Cabot in 2002. Since joining the Company, Ms. McLaughlin has held several key finance and business positions, including her present position of Vice President of Business Operations for the Reinforcement Materials segment and General Manager of the Tire business since June 2016. Ms. McLaughlin was Vice President of Investor Relations and Corporate Communications from 2011 through 2016. In addition, Ms. McLaughlin was Director of Strategy, Planning and Finance for Cabot’s Core segment from 2010 through 2011, Global Finance Director for the Carbon Black division from 2005 through 2010, an Analyst in Cabot’s Corporate Planning and Strategy group, and a Senior Accountant for the External Reporting group.
As an executive officer of the Company, Ms. McLaughlin will participate in the executive compensation plans and programs described in the Company’s proxy statement for its 2018 annual meeting of shareholders as filed with the SEC on January 26, 2018 (the "2018 Proxy Statement"), and the relevant information set forth in the 2018 Proxy Statement is incorporated herein by reference. In connection with Ms. McLaughlin’s appointment, the Compensation Committee of the Board of Directors (the "Committee") of the Company has approved an increase in Ms. McLaughlin’s annual base salary to $400,000 per year, effective May 15, 2018. The Committee also has increased Ms. McLaughlin’s 2018 target bonus amount under the Company’s annual incentive compensation plan to $165,733, which reflects a pro-rata calculation of her prior and new target bonus amounts. In addition, the Committee approved a supplemental equity grant under the Company’s 2017 Long-Term Incentive Plan to Ms. McLaughlin effective May 15, 2018 with a grant date fair market value of $375,000. The grant will consist of 35% performance-based restricted stock units, 30% time-based restricted stock units, and 35% non-qualified stock options, in each case based on the closing price of Cabot common stock on May 15, 2018. These awards will vest on the same schedule as the 2018 long term incentive awards previously granted to Ms. McLaughlin in November 2017, and will otherwise be subject to the same terms and conditions of the awards issued to the Company’s other executive officers generally. The stock options will have a ten-year life. There is no arrangement or understanding between Ms. McLaughlin and any other person pursuant to which she is being appointed Senior Vice President and Chief Financial Officer. There are no transactions involving Ms. McLaughlin requiring disclosure under Item 404(a) of Regulation S-K of the SEC.
The Company issued a press release on April 23, 2018 announcing Mr. Cordeiro’s retirement from the Company and Ms. McLaughlin’s appointment as CFO. A copy of the press release is attached as Exhibit 99.1 to this report.
