Question 1

What is a cash flow statement?

Accepted Answer

A cash flow statement tracks the actual cash moving in and out of a company during a period. It's divided into three sections: operating activities (core business), investing activities (assets and investments), and financing activities (debt and equity). Unlike the income statement, it shows real cash rather than accounting profits.

Question 2

What is operating cash flow?

Accepted Answer

Operating cash flow is the cash generated from a company's core business operations. It adjusts net income for non-cash items like depreciation and changes in working capital. Strong operating cash flow indicates the business can fund operations without external financing.

Question 3

What is free cash flow (FCF)?

Accepted Answer

Free cash flow is operating cash flow minus capital expenditures. It represents the cash available for dividends, share buybacks, debt repayment, or reinvestment. FCF is considered one of the most important metrics for evaluating a company's financial health.

Question 4

What are capital expenditures?

Accepted Answer

Capital expenditures (CapEx) are funds spent on acquiring or maintaining physical assets like property, equipment, and technology. CapEx appears in the investing activities section and is subtracted from operating cash flow to calculate free cash flow.
