6. Property and Equipment, net
Property and equipment, net increased $1.0 billion for the nine months ended September 30, 2022 primarily due to the delivery of Norwegian Prima. We determine the weighted average useful lives of our ships based primarily on our estimates of the useful lives of the ships’ major component systems on the date of acquisition, such as cabins, main diesels, main electric, superstructure and hull, and their related proportional weighting to the ship as a whole. We have assessed the weighted-average useful life of the components of Norwegian Prima and assigned a useful life of 35 years with a 10% residual value to the Prima Class Ships. The useful life and residual value consider the historical useful lives of similar assets, manufacturer recommended lives, planned maintenance programs, anticipated changes in technological conditions and the related proportional weighting of the major components of the Prima Class Ships.
