Icahn and certain affiliated entities, which resulted in the election of a majority of non-incumbent directors to the Company's Board of Directors. As confirmed by general counsel, the election of a majority of non-incumbent directors nominated in connection with the proxy contest resulted in the accelerated vesting of certain share and incentive-based compensation awards granted to the Company's employees and directors as discussed further in Note 17. The Company incurred legal, consulting and advisory fees of $7.1 million related to the proxy contest during the year ended December 31, 2018.
