| Stock option grant date fair values are calculated based on the Black-Scholes option pricing model as of the grant date. Adjustments have been made to the inputs in the Black-Scholes option pricing model to determine the fair value as of each measurement date. Performance stock unit grant date fair values are calculated using a Monte-Carlo simulation model for the TSR-based potion of the award (where applicable) and ROIC for the ROIC-based portion of the award. Adjustments have been made to the inputs into the Monte-Carlo simulation and ROIC calculation as of the measurement date. Restricted stock unit grant date fair values are calculated using the Closing Price of the Company’s common stock as of the grant date. Adjustments have been made using the Closing Price of the Company’s common stock as of the measurement date.
(3) | Dollar amounts shown represent the average of the total compensation amounts reported in the SCT for the Non-PEO NEOs for the Covered Years. The following executive officers served as the Non-PEO NEOs for the following years: (i) for 2022, James Gray, Jorgen Kokke, Nancy Wolfe, and Jeremy Xu; (ii) for 2021, James Gray, Jorgen Kokke, Janet Bawcom, Eric Seip, and Jeremy Xu; and (iii) for 2020, James Gray, Elizabeth Adefioye, Janet Bawcom, and Jorgen Kokke.
(4) | The cumulative TSR for the Company is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. Each of these yearly percentage changes was applied to a deemed fixed investment of $100 at the beginning of the measurement period to produce the Covered Year-end values of such investment as of the end of 2022, 2021 and 2020.
(5) | The cumulative Peer Group TSR utilizes the S&P 1500 Food, Beverage and Tobacco Index (the “Peer Group”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our annual report for the year ended December 31, 2022. For each Covered Year, our Peer Group TSR was calculated based on a deemed fixed investment of $100 through the measurement period, assuming dividend reinvestment for the peer group, weighted according to the respective companies’ stock market capitalization at the beginning of the measurement period.
(6) | Amounts reported represent Net Income attributable to Ingredion as presented in the Company’s audited financial statements for the applicable Covered Year.
(7) | We determined Adjusted EBITDA to be the most important performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs for 2022. Adjusted EBITDA was the highest-weighted financial metric used to determine NEO performance under our Annual Incentive Plan for 2022, as discussed in “Elements of Compensation – Financial Metrics” in the Compensation Discussion and Analysis section of this proxy statement. This performance measure may not have been the most important performance measure for 2021 or 2020, and we may determine that a different performance measure will be the most important performance measure for future years. We define Adjusted EBITDA, which is a non-GAAP financial measure, as income before income taxes, as further adjusted for the following items: depreciation and amortization; financing costs; other non-operating (income); restructuring/impairment charges; acquisition/integration costs; and other matters primarily consisting of charges related to a U.S.-based work stoppage.

The chart below illustrates for the Covered Years the Compensation Actually Paid to our PEO and Non-PEO NEOs in relation to our TSR, as well as our TSR compared to our Peer Group TSR over the same period. In 2020, Compensation Actually Paid was lower than Summary Compensation Table pay for both our PEO and Non-PEO NEOs, which aligned with the decrease in our TSR. Our TSR increased 15% from 2019 to 2022, while our Peer Group experienced a 33% increase in TSR over the same period. We have outperformed our Peer Group during the last two Covered Years . |  |  |
