CBS plans to examine alternatives to Turner’s bid.

The firm said options it will examine include some that it had earlier said it was not considering as part of its effort to thwart a takeover bid by Ted Turner. CBS made the disclosure in an amendment to an April 22 filing with the SEC. But CBS said in its amendment that it “intends to examine various alternatives that may include, without limitation: the issuance of additional securities of the company; the repurchase of outstanding securities of the company; the acquisition or disposition by the company of assets or businesses; changes in the company’s capitalization, and possible business combinations involving the company.”
