Shares of Interpublic Group ( IPG) rose 1.3% after the company said it would delay its annual report and fourth-quarter results and said that it may restate previously issued financial statements. The delay will extend past March 31, which is the due date for filing its 10-K report with the Securities and Exchange Commission. The company said the delay was due to the amount of internal work and analysis required as part of its previously disclosed material weaknesses in internal controls. Interpublic also said that it has identified a number of items that may require a restatement of previous financial statements.

The most significant of these items concerns the way the company consolidated the results of acquired companies during 1996 through 2001. The review is still in the early stages, but Interpublic has identified about $145 million in sales and $25 million in earnings that may have been improperly recognized during those years. Other issues may require a restatement as well, but the company has not yet determined the amounts and periods affected. The company said it plans to get waivers and amendments of its covenants and indentures from debt holders. Interpublic will update the status and timing of its 10-K and earnings release on March 17. Shares traded up 16 cents to $12.51.
