SEGMENT AND ENTITY WIDE DISCLOSURES Segment Reporting Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. During fiscal 2019, Ciena separated its previous Software and Software-Related Services into two stand-alone operating segments. Because Ciena previously disclosed its Platform Software and Services and Blue Planet Automation Software and Services as distinct product lines in its presentation of segment revenue for Software and Software-Related Services, there is no significant change to Cienas presentation of segment revenues as a result of this separation. Comparative periods have been retrospectively adjusted to disclose segment profit for Platform Software and Services and Blue Planet Automation Software and Services. See Note 2 above. Cienas long-lived assets, including equipment, building, furniture and fixtures, Operating ROU assets, finite-lived intangible assets, and maintenance spares, are not reviewed by the chief operating decision maker for purposes of evaluating performance and allocating resources. As of October 31, 2020, equipment, building, furniture and fixtures, net, totaled $272.4 million, and Operating ROU assets totaled $57.0 million both of which support asset groups within Cienas four operating segments and unallocated selling and general and administrative activities.
