Occam Networks has restated results for fiscal 2004, 2005 and the first three quarters of fiscal 2006 because of errors in its historical revenue recognition practices.

On Sunday, the company’s board of directors, based upon the recommendation of its audit committee, decided the company needed to restate the two fiscal years and three quarters of 2006.

The company expects that about $5 million of previously recorded revenue will be deferred as of December 31, 2006 and that, as a result, the net pre-tax loss for fiscal years 2004-2006, taken together, will increase by approximately $2 million.

In the aggregate, approximately $33 million of revenue recognized for fiscal years 2004-2006 was recorded prematurely, though all but the $5 million estimated deferral was ultimately recognizable prior to December 31, 2006. The aggregate of Occam’s previously reported and announced revenue for this period was $125 million, but now it estimates that the aggregate adjusted revenue for this period will be around $120 million.

In the past, Occam has received notices from the NASDAQ stock market that said the company wasn’t in compliance because it hadn’t filed certain periodic reports with the SEC. On Tuesday, Occam received a letter from the NASDAQ that said a panel had granted the company’s request for continued listing on the stock market through Oct. 15, subject to certain conditions.
