"The company has been doing more or less the right things in terms of growing values, and that's why we own 4 million shares for clients," said Gabelli, 72, who has followed Time Warner and its predecessors for more than 40 years. Gabelli once held almost 26 million shares, according to data compiled by Bloomberg.
Bewkes' so-called parachute payment, representing the value of added equity awards and items such as life insurance, is described in the company's annual proxy filing and based on the Dec. 31 stock price, which has since advanced 31 percent. As of Feb. 28, he owned 225,517 Time Warner shares outright, according to the filing, now worth about $19.7 million. As of late April, he had exercisable options on 3.86 million shares.
Keith Cocozza, a spokesman for New York-based Time Warner, declined to comment beyond the filings.
Murdoch's 21st Century Fox, also based in New York, is considering using proceeds from the sale of Italian and German pay-TV assets to boost its Time Warner offer, according to two people familiar with the matter who asked not to be identified.
A surge in Time Warner shares over the past few years has helped erase memories of the disastrous AOL deal and the stock slump that persisted for years. Bewkes and Time Warner, the owner of HBO, CNN and the Warner Bros. studio, said last week it rejected Murdoch's offer, saying the film and television company can deliver better returns on its own.
Bewkes, 62, who started with Home Box Office in the 1970s, rose to become chief executive officer of Time Warner in 2008, while the company was still suffering a hangover from the $114 billion merger with America Online.
The years since the 2008 financial crisis have been profitable for investors in entertainment and media, as companies enjoyed rising advertising sales after the recession, higher fees from pay TV subscribers and burgeoning options for home entertainment via the Web.
Time Warner shares bottomed at $13.97 in March 2009, down 85 percent from when the companies merged. They have more than doubled since 2008 when Bewkes took over -- triple the 34 percent rise of the Standard & Poor's 500 Index over that time, according to data compiled by Bloomberg. Walt Disney Co. rose 167 percent, while 21st Century Fox, owner of the Fox News Channel and Fox movie studio, has gained 94 percent and CBS had added 118 percent. The data reflect price changes, not dividends or spinoffs.
Barbara Brogliatti is among the Time Warner employees who lived through the ill-fated merger. A former executive vice president in corporate communications at Warner Bros., she left the studio in 2008 after 18 years.
"AOL was a debacle and it hurt us all, not just as shareholders but as employees," Brogliatti said in an interview.
She's benefited from hanging on to the stock, selling the last of her shares about six months ago.
"I held the stock to support a company that I loved, and I'm thrilled for anyone that is making more money," Brogliatti said. "They got to where they are today because they are working hard and had a plan. Jeff Bewkes has a plan and it is being well-executed."
Gabelli owned Warner Communications stock in the early 1980s, when then CEO Ross fended off a younger Murdoch, then still an Australian, who had built a stake and was threatening a takeover.
Ross sold a stake in Warner to boat maker Chris-Craft Industries in exchange for partial ownership of some television stations. That effectively blocked Murdoch because of U.S. rules restricting foreign media ownership. Murdoch later became a U.S. citizen. Gabelli called Ross, who died in 1992, "an extraordinarily creative CEO."
Since becoming CEO, Bewkes has busied himself with divesting AOL, Time Warner Cable Inc. and most recently the Time Inc. magazine business, leaving the company with valuable cable networks like HBO and the Warner Bros. studio.
