In another blow to troubled Zale Corp., the company said its financial statements from fiscal years 2008 and 2009 contain errors and are no longer reliable.

Among those errors: Some $41 million in prepaid advertising costs should have been recorded as expenses. In addition, it needs to aggregate approximately $9 million on a pretax basis and record a $4 million charge related to federal income taxes to fiscal 2008. The company will delay filing its 2009 annual statement until Oct. 29th.

Zale’s chief financial officer resigned in January.
