Financial Information

Ciena has a 52 or 53 week fiscal year, which ends on the Saturday nearest to the last day of October in each year. Our quarters also end on Saturdays, most often in 13-week increments, except during a 53 week fiscal year when there is one 14 week quarter. For purposes of financial statement presentation, we describe our quarters as ending on January 31, April 30, and July 31 and our fiscal year as ending October 31.
In addition to reporting GAAP results, Ciena breaks out unusual or extraordinary operating expenses each quarter so that investors can see their affect to GAAP results on an expense-by-expense basis.
