Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE As required by Item 402(v) of Regulation S-K, we are providing the following information on the relationship between Compensation Actually Paid (CAP) and PPL’s performance for our NEOs, including our principal executive officer. CAP is defined by the SEC and is not used by the Compensation Committee in its pay-for-performance assessments. See the Compensation Discussion and Analysis section for a discussion of PPL’s compensation philosophy, practices and programs. PPL’s executive compensation programs are structured to promote a strong pay for performance culture. As noted in the CD&A, 85% of the CEO’s 2022 target compensation was “at-risk” and 72% was performance based. In June 2020, William H. Spence retired from his position as CEO, therefore he is included in the Pay versus Performance Tables as our former CEO. Mr. Sorgi was promoted to the position of President and CEO effective June 1, 2020. In 2021, PPL reported GAAP Net Income losses for the year that were non-cash in nature and primarily related to the sale of the U.K. utility business in June 2021 and certain tax changes in the U.K. Excluding the accounting effect of these one-time events, PPL’s operating businesses and PPL on a consolidated basis had strong financial and operational performance in 2021. Based on our approach to align executive pay closely with performance, PPL’s CAP is directionally aligned with PPL’s Corporate EPS, total shareowner return (TSR), and return on equity. For example, PPL’s TSR declined by approximately 5% over the three-year measurement period, while CEO CAP (relative to Summary Compensation Table disclosure) declined by approximately 10% overall over this three-year period. See the table below for more details followed by a description of the relationship between CAP and select performance metrics. Pay Versus Performance Table

(4) | TSR assumes $100 invested on December 31, 2019, including reinvestment of dividends. Peer TSR represents the EEI Index of Investor-owned Electric Utilities, which is the index used to show performance in our Annual Report.
(5) | In calculating CAP, PPL calculated the fair value (or change in fair value) of outstanding, vested and forfeited equity awards in accordance with SEC rules for CAP and computed in a manner consistent with the methodology for financial reporting purposes consistent with U.S. generally accepted accounting principles. For restricted stock units, CAP values are based on a closing price on applicable year-end date(s) or, in the case of vesting dates, the actual vesting price. For performance units (excluding TSR Awards), CAP values are based on the same valuation methodology as restricted stock unit awards above except year-end values are multiplied times the probability of achievement as of each such date. For TSR-based performance units, the fair value is calculated by a Monte Carlo simulation model that considers stock beta, a risk-free interest rate, expected stock volatility and expected life as of the applicable year-end date(s). For more information about PPL’s share-based accounting, see Note 11 of Notes to Consolidated Financial Statements contained in PPL’s Annual Report for the year ended December 31, 2022.
