Please comply with the following comments in future filings. Confirm in writing that you will do so and explain to us how you intend to comply. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to these comments within ten business days by providing the requested information or advise us as soon as possible when you will respond. If you do not believe our comments apply to your facts and circumstances, please tell us why in your response. After reviewing your response to these comments, we may have additional comments. Form 10-K for the Fiscal Year Ended December 31, 2017 Risk Factors NAI, Through Its Voting Control of the Company, Is in a Position to Control Actions that Require Stockholder Approval, page 25 1. You disclose that National Amusements, Inc. ("NAI") is in a position to control the outcome of corporate actions that require stockholder approval. In light of recent developments, consider expanding your disclosure to address the scope of NAI's control over corporate actions normally reserved for board action, including the specific types of actions that it can take to direct or control the outcome of certain matters. For example, Leslie Moonves FirstName LastNameLeslie Moonves CBS Corporation Comapany NameCBS Corporation August 22, 2018 Page 2 August 22, 2018 Page 2 FirstName LastName discuss whether a controlling stockholder such as NAI has the ability to unilaterally amend your bylaws under the provisions of your Certificate of Incorporation and address the ability of a controlling stockholder to replace directors in order to compel certain results. Additionally, we note your disclosure in your definitive proxy statement that CBS Corporation has a majority of independent directors on its board and maintains independent committees. We further note your disclosure that by maintaining the composition of independent directors on the board, the Company exceeds the requirements for controlled companies pursuant to the NYSE listing standards. However, in your Form 10-Q for the quarter ended June 30, 2018, you disclose recent allegations that NAI has breached its fiduciary duties to CBS stockholders by "abusing their control to threaten the independent corporate governance of the company." In light of these developments, please: Expand your disclosure to explain the basis for the Company's determination that the board operates independently; Address whether any actions have been taken that would cast doubt on or undermine the board's ability to operate independently; Disclose the risk that any mechanism designed to maintain the board's independence, such as the provision in the bylaws allowing for the board to issue a dividend that would have the effect of diluting a controlling stockholder's voting stake, could be deemed invalid or challenged in a derivative action, or could be preempted by the controlling stockholders' ability to take certain actions. NAI, Certain Directors and Members of Management May Face Actual or Potential Conflicts of Interest, page 27 2. We understand that your certificate of incorporation contains certain provisions related to corporate opportunities. Please add a new risk factor disclosing that no officer or director of your Company shall be liable to the Company for breach of any fiduciary duty concerning activities or corporate opportunities relating to Viacom. Describe how the potential conflict of interest could have a material adverse effect on your business, financial condition, results of operations, or prospects. Finally, consider disclosing the provision in your description of the material terms of the Company's capital stock. Free Cash Flow, page II-33 3. We note that your definition of free cash flow excludes discretionary contributions to pre- fund your pension plans. Since free cash flow is typically calculated as cash flow from operations adjusted by capital expenditures, and your definition of free cash flow differs from the typical definition per Question 102.07 of the April 2018 C&DI on non-GAAP measures, please revise the title of this measure in future filings.

Recent newspaper accounts have suggested that an undisclosed provision in the NAI Trust restricts the Trust from voting its controlling interest in CBS in favor of any business combination agreement that would leave NAI with less than 30% of the voting control of the resulting company. If management or the board is aware of such a provision, you should disclose its existence in future filings, and address the effect of such a provision on management's ability to negotiate merger transactions. We remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff.
