Updated from 12:34 p.m. Shares of Viisage ( VISG) were among technology's losers Thursday, falling 17.7% after the identity solutions technology company warned that first-quarter sales would fall below expectations. The company posted a loss of $5.2 million, or 11 cents a share, on sales of $19 million during the fourth quarter.

For all of 2005, the company forecast sales of $73 million to $80 million and said it expects to be profitable. Analysts are expecting earnings of 6 cents a share on sales of $84 million. During the fourth quarter, the company said it "had an internal control deficiency that constitutes a 'material weakness' as defined by the Public Company Accounting Oversight Board's Accounting Standard No. 2. The company has concluded that it had insufficient personnel resources and technical accounting expertise within the accounting function to resolve non-routine or complex accounting measures," it said. As a result, the company's independent auditor will issue an adverse opinion with respect to the company's internal controls over financial reporting. Viisage is currently reviewing all of its internal controls and believes that it will conclude that it had "significant deficiencies, which could constitute a material weakness, in the control processes around information technology systems as well," the company said. Finally, management doesn't believe the control deficiencies will have an impact on its financial strength or business prospects. Shares traded down 97 cents to $4.50.
