Business forms maker Moore Wallace said in independent probe of allegations contained in an anonymous letter has found nothing to substantiate them.

The allegations specified accounting irregularities relating to a claim that the company misused restructuring charges. An external audit by PricewaterhouseCoopers "found no support for the allegations", the company said in a statement.

A separate investigation into the conduct of its chief financial officer is continuing. Mark Hiltwein was suspended with pay last week for allegedly misdating a document supplied to the auditors.

The memo, which outlined the company's restructuring plans, was dated May 2003, but was actually created in early February, the company said.

The U.S. Securities and Exchange Commission and the U.S. Attorney's Office for the District of Connecticut are still conducting an inquiry relating to the anonymous letter and the misdated memo.

News of the Hiltwein suspension led to a 10 per cent drop in Moore Wallace's stock price on Feb. 9. The shares rebounded somewhat Tuesday, up 58 cents to $24.08.

Moore Wallace is in the process of being acquired by U.S.-based RR Donnelley.

The merger is supposed to take effect by the end of the month. Moore Wallace said Tuesday that timetable is still intact.
