The statement you're referring to is called a "Cash Flow Statement". This financial statement provides a summary of the money (cash and cash equivalents) coming into and going out of the firm. It is divided into three main sections: operating activities, investing activities, and financing activities.

1. Operating Activities: This section includes cash received from customers and cash paid to suppliers and employees. It also includes interest and taxes paid, and the net income from operations.

2. Investing Activities: This section includes cash used for investing in assets, as well as the proceeds from the sale of other businesses, equipment or long-term assets.

3. Financing Activities: This section includes cash received from issuing shares or debt, as well as the repayment of debt, the payment of dividends and the repurchase of existing shares.

By analyzing these three sections, one can get a clear picture of where the company's cash comes from, how it's spent, and how the company's activities contribute to its operating, investing, and financing cash flows.
