The Dallas-based diamond and jewelry retailer said on Tuesday 8 September it must finalize a review of accounting of prepaid advertising costs that surfaced during the company's year-end closing process, prompting the latest delay.

Last week, the earnings report was postponed after Zale found certain non-cash adjustments affecting previous results, causing its shares to fall 11 percent.

Zale, which caters to middle-income shoppers, said the adjustments were about $13 million pretax, of which about $6.3 million relates to years prior to fiscal 2000.

A Zale spokesman declined to elaborate on whether the adjustments would benefit or hurt earnings, and what quarters are impacted.

The company has not yet set a new date to announce earnings.

Zale edged down 1 cent to close at $5.85 on the New York Stock Exchange.
