Another former Symbol Technologies ( SBL) executive will plead guilty to accounting fraud charges, according to published reports Thursday. The bar-code scanner maker's shares recently resumed trading after being halted, and were down 15 cents at $14.45 on the New York Stock Exchange. Symbol's former chief accounting officer, Robert Korkuc, is expected to plead guilty in a federal court in Long Island later Thursday, according to reports. He also faces a civil lawsuit alleging accounting misdeeds from the Securities and Exchange Commission. Korkuc, 40, left the firm in March. Robert Asti, a former Symbol sales finance executive, has already pleaded guilty to fraud and conspiracy charges. Asti also faces a civil suit from the SEC. The SEC's investigation of the accounting practices at Symbol are ongoing, according to John Nester, a spokesman for the agency.
