Overview

The income statement, also known as profit & loss (P&L) statement, presents a company's sales and expenses over a period of time. This statement captures the operating health of a company: its ability to generate sales and profitability.

The income statement will not reflect events that are not directly related to the operating strength of the business: loan payments, debt or equity funding, equity disbursements, large purchases of equipment and more.
*To find details on these events, you must refer to the cash flow statement
