AOL Time Warner became the latest of three potential AT&T Broadband bidders to sign a confidentiality agreement with AT&T on a potential deal between the two companies.
The Wall Street Journal reports Friday that AT&T wants to evaluate bids by the end of the month. Comcast Corp. and Cox Communications already signed confidentiality pacts with AT&T.
The bidding war was sparked by Comcast's unsolicited takeover play for AT&T's cable unit in July.
AOL also has been in talks with AT&T about buying back AT&T's 25.5% stake in Time Warner Entertainment, a partnership that owns programming assets and cable systems.
And AOL has said in Securities and Exchange Commission filings that the companies are engaged in a process for registration of AT&T's stake for public sale.
