NEW YORK (AP) -- Cable TV operator Charter Communications stepped up its bid to buy the much larger Time Warner Cable and vowed Monday to bring an offer directly to shareholders after getting rebuffed by Time Warner's management.
Although there is no formal proposal on the table, Charter said it is willing to make a cash-and-stock offer that could be worth up to $38 billion.
The developments come as broadcast and pay-TV channels demand higher fees from cable TV operators to include those channels in customers' cable lineups. Last summer, Time Warner Cable had to drop CBS for about a month because of a fee dispute. The cable company lost more than 300,000 video subscribers in the third quarter partly because of that.
By combining, Charter and Time Warner Cable could increase their negotiating powers with the TV channels — and perhaps reduce the fee increases they pass on to customers.
The cable companies could also develop better apps for customers to watch channels on phones and tablet computers, as they try to retain customers who are increasingly watching video on the Internet.
Charter Communications Inc. said it is prepared to bring the offer directly to shareholders after determining there is "no genuine intent" from Time Warner Cable's management to engage in merger talks. But Charter said it was open to continued talks with Time Warner Cable first.
Charter said it has made repeated overtures to Time Warner Cable for more than six months. In December, Charter was planning an offer of less than $135 per share, including $83 per share in cash, according to published reports at the time. That values Time Warner at up to $38 billion. In Monday's letter, Charter said it was willing to pay in the low $130s, including about $83 in cash.
In a letter to Time Warner Cable CEO Robert Marcus that Charter released Monday, Charter CEO Thomas Rutledge said that instead of engaging in discussions, Time Warner "came back with a verbal offer at an unrealistic price expectation."
Time Warner Cable Inc. did not have an immediate comment.
Marcus took over as Time Warner Cable's CEO on Jan. 1. He told an investor conference last month that the company's current debt level is "prudent," even as other cable TV companies are reportedly examining adding debt to acquire it. His comments suggested that it would be difficult for Charter to come up with an attractive offer to buy the company.
Consolidation talk has percolated throughout the cable TV world ever since billionaire John Malone's Liberty Media Corp. took a 27 percent stake in Charter for $2.6 billion in May. TV distributors are seen banding together to gain more leverage at the bargaining table against media companies that are driving up fees for their TV networks.
Time Warner Cable's stock closed at $132.40 on Monday and rose 1.6 percent to $134.45 in after-hours trading. Shares have risen 35 percent over the past 12 months.
Charter's shares added 1.7 percent to $136.50 in extended trading. They have gained 71 percent over the past year and closed at $134.22 Monday.
