The table below details the adjustments made to the Summary Compensation Table totals for the CEOs, Messrs. Albert Chao and Gilson, to arrive at the “compensation actually paid to the CEO”. Stock option fair values are calculated at each measurement date using a Black-Scholes valuation model, consistent with the approach used to value the awards at the grant date. Stock option fair values as of each measurement date were determined using updated assumptions (the closing stock price of our Common Stock as of the measurement date (ranging from $114.51 to $144.49 for the measurement dates used to calculate compensation actually paid for 2024), risk-free interest rate (ranging from 4.25% to 4.98% for the measurement dates used to calculate compensation actually paid for 2024), expected life (ranging from 1.0 to 4.9 years for the measurement dates used to calculate compensation actually paid for 2024), expected volatility of the price of our Common Stock (ranging from 37.4% to 38.3% for the measurement dates used to calculate compensation actually paid for 2024), and expected dividend yield (ranging from 1.2% to 1.8% for the measurement dates used to calculate compensation actually paid for 2024). Restricted stock unit fair values are calculated at each measurement date based on the closing stock price of our Common Stock as of the measurement date (ranging from $28.07 to $61.71 for the measurement dates used to calculate compensation actually paid for 2024). Performance stock unit fair values are calculated using a Monte Carlo simulation model, consistent with the approach used to value the awards at the grant date. Performance stock unit fair values as of each measurement date were determined using updated assumptions (risk-free interest rate (ranging from 4.16% to 4.25% for the measurement dates used to calculate compensation actually paid for 2024), volatility of the price of our Common Stock (32% for the measurement dates used to calculate compensation actually paid for 2024), the closing price of our Common Stock on the measurement date ($114.65 for the measurement dates used to calculate compensation actually paid for 2024), volatilities of the prices of the stocks of the peer group companies, and the correlations of returns of our Common Stock and the stocks of the peer group companies to simulate total shareholder returns and their resulting impact on the payout percentages).

The peer group for fiscal year 2024 is the S&P 500 Chemicals Industry GICS Level 3 Index (“S&P 500 Chemicals”). In fiscal years 2020 through 2022, the Company’s selected peer group was the Chicago Board Options Exchange S&P Chemicals Index, or CEX, which was discontinued on September 13, 2023. As a result, in 2023 the Company replaced the CEX with the S&P 500 Chemicals for fiscal year 2023 for purposes of the
Pay-Versus-Performance
Compensation Table and the graph below. The companies included in the S&P 500 Chemicals and CEX were generally the same at each measurement date. Accordingly, the cumulative total returns for the S&P 500 Chemicals and CEX were highly correlated through September 13, 2023, the date that the CEX was discontinued, although the cumulative total return of the S&P 500 Chemicals was marginally higher at each measurement date.

Net income for fiscal years 2020, 2021, 2022, and 2023 show net income, including net income attributable to noncontrolling interests, as reported in the Company’s audited financial statements for the applicable fiscal year.
(7)
EVA generated by the Company was determined by subtracting from the Company’s net operating profit after taxes (“NOPAT”) a charge of 8.75% of the capital employed to generate the profit. The 8.75% capital charge represents the Company’s estimate of its weighted average cost of debt and equity capital. EVA is solely a measure used by the Company under its compensation programs. It is not the same as the corresponding accounting measures calculated in accordance with U.S. GAAP for financial reporting purposes and is not intended to reflect the Company’s performance for any purpose other than determination of bonuses awarded under the AIP, the QIP and the amount of performance stock units earned. NOPAT is adjusted to account for any amortization of intangibles, acquisition-related integration and transaction costs, adjustments associated with acquisitions, impairment and restructuring costs (together,
“non-operating
impacts”) amortized over a period commensurate with the period which the Company realizes benefits, and noncontrolling interests. Capital employed represents the Company’s total assets minus cash, restricted cash, current liabilities (but excluding the current portion of long-term debt) and pensions and other post-retirement benefits. Capital employed is adjusted to remove the impact of significant capital projects,
non-controlling
interests, the difference between an acquired company’s opening balance sheet and the purchase price for such acquired company, any impact based on the Company’s actual taxes paid as compared to the long-term expected cash tax rate used for NOPAT and adding back historical adjustments to NOPAT based on
non-operating
impacts.
