Sportmaster, the leading sporting goods retailer in Russia and former Soviet republics, is considering an initial public offering in London next year, two financial market sources told Reuters.  Sportmaster could attract between $600 million and 700 million in the IPO based on its own valuation of $2.5 billion to $3 billion, sources said.

Renaissance Capital forecasts Sportmaster's revenue for the 2010 financial year ending Aug. 31 at $1.3 billion and earnings before taxes, interest payments, depreciation and amortization at $306 million.
