Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events On April 13, 2018, Carl C. Icahn and certain affiliated entities (together, “Icahn”) delivered to the Company formal notice of its intention to nominate five directors for election to the Board at the Annual Meeting, and on April 24, 2018, Icahn filed a preliminary proxy statement to that effect. As a result of the contested election, we expect to incur significant costs during 2018, including a fee of approximately $4.0 million that will be paid to our strategic adviser in the second quarter of 2018, as well as other ancillary costs throughout the process.
