An apportionment is the separation of revenues, expenses, or profits, which are then assigned to different accounts, departments, or subsidiaries. The concept is used in particular for the assignment of profits to different geographic regions of a business, which impacts the taxable profits reported to different governments. For example, the total income of a multi-state entity could be apportioned to its state-level subsidiaries based on their individual sales, headcount, asset base, or cash receipts.
