(Recasts with tax settlement)
July 27 (Reuters) - Canada's Cameco Corp, the world's second-largest uranium producer, said on Thursday it had settled a U.S. tax dispute for a fraction of the original claim, which may bode well for the company's multi-billion-dollar battle with the Canada Revenue Agency.
Cameco will pay the U.S. Internal Revenue Service $122,000 for its 2009 through 2012 taxation years, compared with the $122 million the IRS claimed Cameco underpaid.
The company's shares rose 3 percent to C$12.94 in early trading in Toronto, as the settlement news helped investors look past the company reporting a wider-than-expected quarterly loss.
Cameco's dispute with tax authorities relates to its offshore marketing structure and transfer pricing. Cameco sells uranium to its marketing subsidiary in Switzerland, which re-sells it to buyers, incurring less tax than the company would through its Canadian office.
Cameco says it has a marketing subsidiary there because most of its customers are located outside Canada.
Cameco's dispute with CRA, which is before Canadian courts, could result in a C$2.4 billion ($1.92 billion) tax expense for past years, the company said on Thursday.
"It is tempting to conclude that this (IRS settlement) weakens the CRA's position," BMO analyst Edward Sterck said in a note.
A spokesman for CRA could not immediately comment.
The global uranium industry is locked in a six-year slump, dating back to the 2011 tsunami that caused Japan to shutter all of its nuclear reactors. The world's uranium market is oversupplied, although some reactors in Japan have restarted.
Cameco reported a loss of C$1.56 million in the second quarter, breaking even on a per share basis.
It had posted a loss a year earlier of C$137.4 million, or 35 Canadian cents.
The latest quarter's results were hit by the loss of a contract with Tokyo Electric Power (Tepco), the operator of Japan's wrecked Fukushima nuclear plant.
The company said it was addressing low uranium prices by reducing supply and avoiding sales into a weak spot market.
Adjusted for one-time items, Cameco lost 11 Canadian cents per share, disappointing analysts who had expected, on average, a loss of 2 Canadian cents a share, according to Thomson Reuters I/B/E/S.
Revenue rose 1 percent to C$469.7 million.
The company's uranium sales rose 33 percent to 6.1 million pounds, while its average realized uranium price fell 14.9 percent to $36.51 per pound. ($1 = 1.2482 Canadian dollars) (Reporting By Aparajita Saxena in Bengaluru and Rod Nickel in Winnipeg, Manitoba; Editing by Meredith Mazzilli)
