Oglebay Norton Company, an Ohio corporation (the "Company"), with the concurrence of Ernst & Young LLP, its independent registered public accounting firm ("E&Y"), has determined that the Company incorrectly calculated its "Per Share Amounts - Basic and Assuming Dilution" as reflected in its Unaudited Condensed Consolidated Statement of Operations in its quarterly reports on Form 10-Q for each of the periods ended March 31, 2005 and June 30, 2005.  Accordingly, the Company will file amendments to each of those reports to restate "Net loss per share - basic and assuming dilution" and to revise the associated "Note J - Stock Compensation," "Note M - Net Loss Per Share" and Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
As explained in these quarterly reports as originally filed, the Company calculated "Net loss per share - basic and assuming dilution" by dividing "Net Loss" as reflected in its Unaudited Condensed Consolidated Statement of Operations by the average number of shares outstanding.  This approach was discussed with and concurred in by E&Y.  Subsequently, in connection with the preparation of the Company's quarterly report on Form 10-Q for the quarter ended September 30, 2005, the Company was informed by E&Y that the calculation made in these prior reports was incorrect, and that the correct calculation is to divide "Net Loss Available to Common Shareholders" as reflected in the Company's Unaudited Condensed Consolidated Statement of Operations, by the appropriate average number of shares outstanding during the respective periods.
