What Is Cash Flow Statement?

The cash flow statement tracks all cash inflows and outflows during a period, organized into operating, investing, and financing activities. It reconciles accrual-based net income to actual cash generated and is considered the most important statement for assessing true financial health.

Formula

CFO = Net Income + Non-Cash Charges ± Working Capital Changes CFI = −CapEx − Acquisitions + Asset Sale Proceeds CFF = Debt Issued − Debt Repaid + Equity Issued − Buybacks − Dividends Ending Cash = Beginning Cash + CFO + CFI + CFF

What Is the Cash Flow Statement?

The cash flow statement answers the most practical question: how much cash did the company actually generate or consume during the period? It reconciles accrual-based profitability to real cash movement.

Three Sections

Cash from Operating Activities (CFO) starts with net income and adjusts for non-cash items (D&A, SBC, deferred taxes) and working capital changes. CFO reflects core business cash generation.

Cash from Investing Activities (CFI) includes capex, acquisitions, investment purchases/sales, and asset sale proceeds. Typically negative for growing companies.

Cash from Financing Activities (CFF) includes debt issuance/repayment, equity issuance/buybacks, and dividends. Shows how the company finances operations and returns capital.

Beginning cash plus the sum of all three sections equals ending cash, which matches the balance sheet.

Indirect Method

Most companies use the indirect method: start with net income, add back non-cash items, and adjust for working capital changes. This clearly shows the reconciliation between accrual income and cash flow.

Why CFO Is King

Sustainable positive CFO means the business funds itself. If net income consistently exceeds CFO, it may signal aggressive accounting or deteriorating working capital. The CFO/Net Income relationship reveals earnings quality.

FCF Approximation

CFO minus capex (from investing section) approximates free cash flow. This quick calculation is useful for screening but may not match a precise FCF calculation.

Cash Flow Statement in Banking

In financial modeling, it is the last statement built (depends on income statement and balance sheet). In LBO models, it determines annual debt paydown. In credit analysis, CFO and FCF are primary debt service metrics.

Example

Net income $200M, D&A $80M, SBC $30M, WC increase $20M, capex $100M, acquisitions $50M, debt repaid $60M, dividends $40M. CFO = $290M. CFI = −$150M. CFF = −$100M. Net change = +$40M.

Why Interviewers Ask About This

The cash flow statement is the ultimate test of accounting understanding in IB interviews. It connects the income statement to the balance sheet and reveals whether profits translate into cash. Interviewers expect you to walk through the indirect method, explain non-cash addbacks, describe working capital impacts, and trace transactions through all three statements.

Common Mistakes

Confusing CFO with total free cash flow — capex must be subtracted

Not understanding why D&A is added back (non-cash deduction from net income)

Getting signs wrong on working capital — increase in current assets is a cash outflow

Forgetting ending cash must equal the balance sheet cash balance

Frequently Asked Questions

Why is depreciation added back on the cash flow statement?

D&A was subtracted on the income statement (reducing net income) but is non-cash. The actual cash outflow was capex when the asset was purchased. Adding D&A back corrects for this non-cash deduction.

What is more important — the income statement or cash flow statement?

Most practitioners consider the cash flow statement more important because cash is king. A company can show profits while running out of cash, but it cannot operate without cash. The cash flow statement reveals true cash-generating ability.

How do working capital changes affect operating cash flow?

Increases in current assets (AR, inventory) reduce CFO as cash is tied up. Increases in current liabilities (AP, deferred revenue) increase CFO as cash is preserved or collected early. The net effect appears in operating activities.
