Pay vs Performance Disclosure [Table]

Pay vs Performance [Table Text Block]

Pay-Versus-Performance

The following section has been prepared in accordance with the SEC’s new pay versus performance disclosure rules mandated by the Dodd-Frank Act. Under these rules, the SEC has developed a new way to calculate executive pay, referred to as “compensation actually paid,” or CAP, which amounts are then compared to certain performance measures defined by the SEC. The CAP does not reflect the value received or realized by our NEOs or how the compensation committee evaluates compensation decisions in light of company performance. Please refer to “Compensation Discussion and Analysis” on page 40 for a discussion of our executive compensation program objectives and the ways in which we design our program to align executive compensation with company performance.

The CAP values are derived from the total compensation amounts reported in the Summary Compensation Table, but adjusts those amounts to replace the grant date fair values of equity awards granted during the year with the fair value of equity awards granted during the year as of the end of the year, plus changes in fair value of any outstanding unvested awards granted in prior years. Thus, unlike the Summary Compensation Table that only factors in current year equity awards, the CAP reflects year-over-year changes in value of all outstanding unvested equity awards and equity awards vesting during the year. The CAP values also replace the change in pension value reported with the pension plan service cost or prior service cost for the year.

Represents the weighted peer group total stockholder return, or “TSR,” weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: S&P Metals and Mining Select Industry Index, which is the industry line peer group reported in our performance graph under Item 201(e) of Regulation S-K included in our Annual Report.

The amounts reported in this column represent the CAP for Mr. Adkerson, as computed in accordance with Item 402(v) of Regulation S-K. The amounts do not reflect the actual amount of compensation earned by or delivered to Mr. Adkerson during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments reflected in the table below were made to Mr. Adkerson’s total compensation for each year reflected in the Summary Compensation Table (SCT) to determine the CAP values. Mr. Adkerson has reached the maximum years of service under the SERP and thus Freeport did not recognize a service cost for him during any of the years reflected in the table.

(A)

In determining the fair value of unvested equity awards, we applied the same methodology used to determine grant date fair value of equity awards for purposes of accounting for share-based payments as described in our 2022 Form 10-K, but calculated fair value as of the last day of the year. Factors impacting the fair value of the equity awards primarily relate to the price of our common stock at year end, as well as the projected and actual achievement of performance goals related to our PSUs.

Our NEOs (other than Mr. Adkerson) for each fiscal year included in the table were as follows: 2022 – Kathleen L. Quirk, Maree E. Robertson, Stephen T. Higgins, and Douglas N. Currault II; 2021 – Kathleen L. Quirk, Stephen T. Higgins, and Douglas N. Currault II; 2020 – Kathleen L. Quirk and Harry M. Conger. The amounts reported in this column represent the average of the total compensation reported for each named executive officer (excluding Mr. Adkerson) in the Summary Compensation Table in each applicable year.

(4)

The amounts reported in this column represent the average CAP for the NEOs as a group (excluding Mr. Adkerson), as computed in accordance with Item 402(v) of Regulation S-K. The amounts do not reflect the actual average amount of compensation earned by or delivered to the NEOs as a group during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments reflected in the table below were made to the average total compensation for the NEOs for each year reflected in the Summary Compensation Table on page 53 to determine the CAP values. Mr. Conger and Mr. Higgins, the only other NEOs who have pension benefits, each reached the maximum years of service under the SRP and thus Freeport did not recognize a service cost for either executive during any of the years reflected in the table.

Performance Measures

As described in greater detail in “Compensation Discussion and Analysis,” our executive compensation program reflects a pay-for-performance philosophy. The metrics that we use under our AIP and LTIP are selected with the objective of linking our NEO’s compensation to the key metrics driving our future growth and incentivizing our NEOs to focus on critical elements of our strategic priorities each year. In accordance with the requirements of Item 402(v) of Regulation S-K, the most important financial and non-financial performance measures used to link executive compensation actually paid to our NEOs, for the most recently completed fiscal year, to our performance are as follows:

While we use numerous financial and non-financial performance measures for the purpose of evaluating performance under our AIP and LTIP, we believe that ROI represents the most important performance measure (that is not otherwise required to be disclosed in the table) we use to link compensation actually paid to our executive officers to company performance. Per SEC guidance, the table reflects our annual ROI for each year; however, we use a three-year average ROI to measure performance for purposes of the PSUs granted under our LTIP.
