Gerber Scientific (GRB) is conducting an internal review of its financial reporting from Jan. 1, 1998, through the current fiscal year, which ends April 30. The company launched the review in response to an investigation by the Securities and Exchange Commission, which has been looking into Gerber's inventory and reserve accounting practices and related disclosures. Based on the information Gerber has to this point, the company believes it will likely have to restate certain previous financial results. The company also said it expects to record a fourth-quarter pretax charge of about $12 million, primarily to write down inventory. The stock was down 11% to $6.98.
