Segment and Geographical Information Segment and Geographical Information
We report our financial results for our two reportable segments: Family of Apps (FoA) and Reality Labs (RL). FoA includes Facebook, Instagram, Messenger, WhatsApp, and other services. RL includes our augmented, mixed and virtual reality related consumer hardware, software, and content. Our operating segments are the same as our reportable segments.

Our chief executive officer is our chief operating decision maker (CODM), who allocates resources to and assesses the performance of each operating segment using information about the operating segment's revenue and income (loss) from operations. Our CODM does not evaluate operating segments using asset or liability information.

Revenue and costs and expenses are generally directly attributed to our segments. These costs and expenses include certain product development related operating expenses, costs associated with partnership arrangements, consumer hardware product costs, content costs, legal-related costs, and severance costs. Indirect costs are allocated to segments based on a reasonable allocation methodology, when such costs are significant to the performance measures of the operating segments. Indirect cost of revenue is allocated to our segments based on usage, such as costs related to the operation of our data centers and technical infrastructure. Indirect operating expenses, such as facilities, information technology, certain shared research and development activities, recruiting, physical security expenses, and certain restructuring costs, are mostly allocated based on headcount.
