Segment Information Our operating segments are reported on the same basis as the internally reported information that is provided to our chief operating decision maker (CODM), who is the President and Chief Executive Officer of Carnival Corporation and Carnival plc. The CODM assesses performance and makes decisions to allocate resources for Carnival Corporation &amp; plc based upon review of the results across all of our segments. Our four reportable segments are comprised of (1) NAA cruise operations, (2) EA cruise operations, (3) Cruise Support and (4) Tour and Other. The operating segments within each of our NAA and EA reportable segments have been aggregated based on the similarity of their economic and other characteristics, including geographic guest sourcing. Our Cruise Support segment includes our portfolio of leading port destinations and other services, all of which are operated for the benefit of our cruise brands. Our Tour and Other segment represents the hotel and transportation operations of Holland America Princess Alaska Tours and other operations.
