Item 5.04    Temporary Suspension of Trading Under Registrant's Employee Benefit Plans.

On November 17, 2017, a notice was sent to CBS Corporation’s (“CBS”) directors and executive officers (the “Updated Notice”), which updated the notice sent to them on October 19, 2017 regarding restrictions on their purchasing, selling or otherwise acquiring or transferring shares of CBS Class A common stock, CBS Class B common stock and derivative securities, subject to certain exceptions, in connection with CBS’ offer to exchange its shares of CBS Radio Inc. common stock for shares of outstanding CBS Class B common stock, which was launched on October 19, 2017 (the “Exchange Offer”). The notice indicated that such trading restrictions would begin on November 10, 2017, at 1:00 p.m. Eastern Time, and end during the week of December 3, 2017 but could be shortened if the number of participants in the CBS 401(k) Plan and CBS Radio 401(k) Plan who participate in the Exchange Offer (“401(k) Participants”) did not meet a threshold.  The Updated Notice indicated that the number of 401(k) Participants was less than the threshold and, as a result, CBS’ directors and executive officers were no longer subject to trading restrictions pursuant to Section 306 of the Sarbanes-Oxley Act of 2002 and Regulation BTR (Blackout Trading Restriction).


Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
