KAISER ALUMINUM CORP

We conduct robust annual board, committee and director assessments. Under our corporate governance guidelines, our board of directors is required to conduct an annual self-evaluation to determine whether our board of directors, its committees and directors are functioning effectively. As part of the annual evaluation, the board of directors also assesses whether the board of directors and individual directors possess the strategic board skills, experience and attributes identified by the board of directors as priorities as it considers our strategy and board succession planning. At least once every three years, the board of directors utilize a third party evaluator to facilitate the annual evaluation and assessment, including interviews with individual directors. The results from the interviews are summarized and reviewed with the nominating and corporate governance committee and the board of directors. The Lead Independent Director and Chairman also meet with each director individually to discuss board and committee performance.

The charter for each committee of our board of directors also requires each committee to annually evaluate its performance. The nominating and corporate governance committee reviews the annual evaluation process and modifies the process as it deems appropriate. In addition, we coordinate with the USW not less than annually to discuss (i) our most recent assessment of strategic board skills, experience, attributes of all directors, (ii) desired strategic board skills, experience, attributes and priorities in the context of anticipated vacancies and upcoming elections and (iii) each board member nominated by the USW and contemplated future USW nominees in light of these considerations.
