Yahoo will live up to its promise to pay its shareholders most of the money from a $7.6 billion deal with the Chinese Internet company Alibaba Group. Yahoo reassured its shareholders Tuesday a few hours after Alibaba disclosed it had completed a complex transaction announced four months ago. At that time, Yahoo pledged to distribute most of the proceeds to shareholders who have been frustrated with the company's slumping stock price. Yahoo now estimates shareholders will receive $3.65 billion of the $4.3 billion remaining from the Alibaba deal after taxes.
