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.

Ciena's long-lived assets, including equipment, building, furniture and fixtures, right-of-use (“ROU”) assets, finite-lived intangible assets, and maintenance spares, are not reviewed by Ciena's chief operating decision maker for purposes of evaluating performance and allocating resources. As of April 27, 2024, equipment, building, furniture and fixtures, net, totaled $274.4 million, and operating ROU assets totaled $30.2 million both of which support asset groups within Ciena’s four operating segments and unallocated selling and general and administrative activities. As of April 27, 2024, finite-lived intangible assets, goodwill, and maintenance spares are assigned to asset groups within the following segments (in thousands):

Segment Profit (Loss)

Segment profit (loss) is determined based on internal performance measures used by Ciena’s chief executive officer to assess the performance of each operating segment in a given period. In connection with that assessment, the chief executive officer excludes the following items: selling and marketing costs; general and administrative costs; significant asset impairments and restructuring costs; amortization of intangible assets; acquisition and integration costs; interest and other income, net; interest expense; and provision for income taxes.

The table below sets forth Ciena’s segment profit (loss) and the reconciliation to net income (loss) for the periods indicated (in thousands):
