The performance goals for the PSEs are the adjusted earnings per share of the Company for its 2021 fiscal year, the adjusted cumulative free cash flow of the Company for its 2021 fiscal year as a percentage of adjusted net sales of the Company for fiscal year 2019 through fiscal year 2021, and the achievement of targeted Project Fuel savings for the period ended September 30, 2021.
