Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE As noted in the CD&A above, our Compensation Committee is committed to aligning compensation paid to executives with Company performance as well as the achievement of individual goals. Such alignment is reached through the use of both short-term and long-term incentives. Through the AIP, our NEOs are rewarded for achieving annual corporate and individual goals, while the long-term incentive compensation program is designed to reward our NEOs for long-term TSR performance, measured over a three-year period. As described in the CD&A, the Compensation Committee believes there are five important measures used to link compensation actually paid with our performance during the most recently completed fiscal year. In response to the SEC rules and regulations and to comply with the SEC’s disclosure requirements, the table below sets forth the Company-selected adjusted EBITDA performance metric along with the required TSR and net income metrics. Accordingly, the following table and related footnotes provide information regarding the relationship between NRG’s cumulative TSR relative to its peer performance group pursuant to SEC rules and regulations, as well as compensation actually paid relative to NRG’s TSR, net income, and adjusted EBITDA, over the three most recently completed fiscal years. As described in more detail in the CD&A, our Compensation Committee assesses target compensation and potentially realizable compensation in addition to compensation actually paid to maintain a fulsome understanding of executive total compensation packages. In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive compensation for our principal executive officer (PEO) and Non-PEO NEOs and Company performance for the fiscal years listed below. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.
