Big 5 Sporting Goods

(BGFV) - Get Report

fell 6.2% after the company posted fourth-quarter earnings, disclosed that it would restate its financials going back to 2001, and warned that 2005 earnings would be lower than expected. The sporting goods company said the restatement stems from an error in an account within accounts payable. The company expects an impact on earnings of about $4.7 million. As a result of the restatement, Big 5 anticipates a refund or credit of about $3.2 million due to an over-payment of income taxes during the affected periods.

Shares of

Whole Foods Market
