con't 2  How much money he made is really anyone’s guess. When Mr. Nevo began appearing a few years ago on certain lists, like Vanity Fair’s New Establishment list, Forbes tried to gauge Mr. Nevo’s wealth to see if he belonged on the magazine’s list of billionaires, but ultimately gave up trying. Mr. Nevo owns homes in Malibu, Calif.; the Los Angeles-area neighborhood of Brentwood; the TriBeCa neighborhood of New York; London; and two homes in Tel Aviv, including his modest childhood home outside the city, which sits empty. In addition, he and Ms. Zhang recently bought a home in Beijing.  “Vivi is a very hard worker, and we’d begin chatting about the markets in the early morning, and then we’d talk late in the afternoon,” said Bob Packer, who ran Goldman Sachs’s institutional equities unit in San Francisco and handled many of Mr. Nevo’s trades. “He loved working with the markets. He’s just a really affable, wonderful, loyal guy.” In the case of Time Warner, his relationship with the company and its executives began in the early to mid-1990s, when he established a relationship with Gerald M. Levin, then chief executive.  “It was in a social context,” Mr. Levin said, trying to recall how he met Mr. Nevo. “I would go to every major fight that HBO had in Las Vegas. It was either at the fights in Las Vegas or at some movie premiere. No, I think it was in Vegas.” “I spoke to him about Time Warner and what we were doing. Increasingly, he got interested. Unlike some other financial players, he has an interest not just in the financial aspect itself but also the personalities. The social nexus is part of his understanding and analysis.” pic Zhang Ziyi, left; Richard Parsons, Time Warner chairman; and Vivi Nevo.  CreditMatthew Staver/Bloomberg News
