Earnings roundup: Google, Union Pacific

Among the earnings stories for Thursday, Oct. 18, from AP Business News:

_ Google Inc.'s stock plunged after a contractor released the search company's third-quarter earnings report early, by mistake.

_ Union Pacific Corp. said that its third-quarter profit climbed 15 percent because price increases and more automotive and chemical shipments helped the railroad offset a 12 percent drop in coal shipments.

_ Reinsurance Group of America Inc.'s net income rose 7 percent in the third quarter, but the company said its operating income declined, mostly because of higher-than-expected claims in the U.S. and Australia.
