Shares of Sirva ( SIR) were big NYSE losers Monday, falling 38.5% after the relocation services company warned that its fourth-quarter earnings would miss estimates because of accounting issues in its insurance and European operations.

The company now expects to post a loss of 16 cents to 20 cents a share. Previously, it expected earnings of 15 cents to 17 cents a share. Analysts polled by Thomson First Call had been expecting earnings of 16 cents a share. A review of its accounting practices and significant balance sheet accounts turned up pretax charges of $21 million to $25 million, or 18 cents to 22 cents a share. "The review was undertaken in connection with implementing procedures to comply with section 404 of the Sarbanes-Oxley Act, the disappointing performance of the company's insurance and European businesses in the third quarter of 2004, and as part of its year-end closing process," the company said. The news comes just a week after the company announced the resignation of Joan Ryan, its CFO. Shares traded down $5.54 to $8.86.

The company's results, which were helped by a 30% sales jump in the entertainment division, were good enough to beat expectations despite what it called a "challenging retail environment." Shares traded up $1.10 to $19.45.
