BANGALORE (Reuters) - Footwear retailer Collective Brands Inc (PSS.N: Quote, Profile, Research) forecast higher-than-expected first-quarter results and sought to allay fears about a recent unfavorable verdict it got in a patent suit filed by larger rival Adidas (ADSG.DE: Quote, Profile, Research), boosting its shares 19 percent.

The company, which was hit with a $305 million verdict last week in a trademark infringement case filed against it by Adidas, said it expects quarterly earnings of 61 cents to 67 cents a share on sales of $932 million.

Analysts on average had expected the holding company of Payless ShoeSource and Collective Licensing International to earn 56 cents a share, before special items, on revenue of $922.7 million, according to Reuters Estimates.

The strong forecast succeeded in calming investors, who had sent the shoe maker's shares down more than 18 percent since news of the Adidas patent verdict.

The company called the verdict "excessive and unjustified," and said it would file several motions asking the court to set aside the verdict and either enter judgment in its favor or order a new trial, or reduce the jury's award substantially.

The outlook boost was not an effort to reassure investors after the verdict Collective Brands got in the Adidas patent suit, Susquehanna Financial Group analyst John Shanley said from New York. He said the "realistic" forecast was mostly based on revenue improvement and a favorable tax rate.

Collective Brands is benefitting from having a greater percentage of its business done in international markets with lower tax jurisdictions, Shanley, who has a "positive" rating and $16 price target on the stock, said.

Headquartered in Topeka, Kansas, the company operated 4,552 retail stores in 15 countries as of year-end 2007 under the Payless Shoe Source brand.
