Just a day after naming a new vice chairman, Warner Bros. Entertainment selected a new chief financial officer on Thursday. The Burbank film and TV studio selected Kim Williams, a former NFL and NBC executive, as the new CFO. “Kim is a proven finance pro with an impressive track record and a background that fits perfectly with our needs,” said Warner Bros. Chief Executive Kevin Tsujihara in a statement. The studio announced Wednesday that Ed Romano would leave the CFO job to assume the newly created position of vice chair. Romano has worked at Warner Bros. for 46 years. In his new position, Romano will implement a strategy of “international expansion, digital transition and resource reallocation from mature businesses to high opportunity, content-creating divisions,” the company said in a statement. Last month, the studio announced plans to cut 1,000 jobs and streamline costs. Warner Bros. is a unit of Time Warner Inc. in New York. Shares of Time Warner closed up 10 cents, or less than 1 percent, to $83.31 on the New York Stock Exchange.
