Segment Reporting

Our Chief Operating Decision Makers (CODMs), which consist of the Chief Executive Officer and the President, review our consolidated results within one operating segment. In making operating decisions, our CODMs primarily consider consolidated financial information accompanied by disaggregated revenue information by geographic region.

We eliminate all intercompany revenues in computing revenues by geographic regions. Revenues related to operations in the geographic regions were as follows:

	Three months ended April 30,
	2016		2015
Revenues:
United States	$	83,220	$	129,191
Europe	54,874		46,319
Japan	37,932		21,417
Pacific Rim	48,967		70,129
Other	2,646		5,087
Total revenues	$	227,639	$	272,143

For the three months ended April 30, 2016, no customer accounted for 10.0% or more of our total revenues. For the three months ended April 30, 2015, one customer accounted for 17.0% of our total revenues.
