Charter had bid about $132.50 per share, or $37.3 billion, for Time Warner Cable last year before being beaten by Comcast Corp (CMCSA.O), whose all-stock deal was initially worth $158.82 per share. Comcast abandoned its $45 billion offer for Time Warner Cable last month after U.S. regulators raised concerns the deal would have given Comcast an unfair advantage in the cable TV and Internet-based services market. TWC declined to comment, while Charter had no comment on the report.
