Categories on the income statement include all the following except:

The income statement is a financial report that summarizes a company's revenues, expenses, and net income over a specific period. Its primary categories include revenue, which represents the total income generated from sales of goods or services; expenses, which encompass the costs incurred in generating that revenue; and net income, which reflects the profit or loss calculated as revenue minus expenses.

Inventory, however, does not appear on the income statement. Instead, inventory is classified as an asset on the balance sheet, representing goods that a company has on hand and intends to sell. It plays a critical role in determining the cost of goods sold (COGS), which does indirectly affect the income statement, but inventory itself is not directly reported as a category on the income statement. The focus of the income statement is on flow-related figures (revenues and expenses) rather than stock-related figures (assets like inventory).
