Yahoo is in line to make anywhere from $8.3 billion to $9.5 billion from the initial public offering, depending on whether investment bankers exercise their right to buy additional stock in the deal. The payoff supplements the $7.6 billion jackpot that Yahoo collected two years ago after selling another chunk of its Alibaba holdings and reworked a licensing agreement with the Chinese company. The downturn has occurred even as advertisers steadily shift more of their budgets to the Internet and mobile devices, but most of that money is flowing to Yahoo rivals such as Google Inc.
