United sues owner of complaint website

United Continental Holdings Inc. sued a Canadian professor who maintains the 15-year-old complaint website Untied.com, which airs complaints from disgruntled United Airlines passengers and employees. Two suits filed in Canadian courts allege the complaint site violates the airline's copyright and trademarks.

NCR deal beefs up its supermarket presence

NCR Corp., a supplier of automated teller machines and payment systems, agreed to buy Retalix Ltd. for about $650 million, gaining software and services used in supermarkets.

Europeans approve Spanish bank bailouts

The European Commission approved a payment of 37 billion euros ($48 billion) from the eurozone bailout fund to four Spanish banks on the condition that they lay off thousands of employees and close offices as part of their restructuring. Some of the biggest job cuts were expected to be made by Bankia, the giant lender whose collapse and request for 19 billion euros of additional capital last May forced Madrid a month later to negotiate a banking bailout of up to 100 billion euros. The funds approved Wednesday are part of that negotiated amount and will be disbursed from the European Stability Mechanism, the bailout fund for the eurozone.

Disney boosts dividend ahead of tax changes

Walt Disney Co., the world's largest entertainment company, raised its annual dividend by 25 percent, joining other companies boosting their payouts ahead of an expected increase in tax rates. The 75-cent-a-share payment will be made on Dec. 28 to shareholders as of Dec. 10, the Burbank, Calif.-based company said. The previous 60-cent annual dividend was paid to investors in January. The move protects Disney investors from a possible increase in the dividend tax rate, which is set to rise as high as 39.6 percent from 15 percent with the year-end expiration of Bush-era tax cuts.

Shares of Russia's MegaFon drop in debut

Investors balked at the initial public offering of MegaFon, Russia's second-largest cellphone operator, as the company's shares fell Wednesday in the first day of trading.

MegaFon, whose majority owner is Alisher Usmanov, one of Russia's richest men, had priced its stock at $20 a share, the bottom of the expected price range. By the close of trading Wednesday, the company's shares, which are jointly traded in Moscow and London, fell 2 percent, to $19.60.
