Cash Flow Statement
Think of the cash flow statement as the reality check on the income statement — it strips away accounting tricks and shows you the actual cash moving in and out of the business.
Definition
The cash flow statement reconciles net income from the income statement to actual cash generated or consumed during a period. It is divided into three sections: Cash from Operations (CFO), Cash from Investing (CFI), and Cash from Financing (CFF).
Formula
Net Income + Non-Cash Charges (D&A, SBC) - Changes in Working Capital = Cash from Operations (CFO) - CapEx - Acquisitions = Cash from Investing (CFI) + Debt Issued - Debt Repaid + Equity Issued - Buybacks - Dividends = Cash from Financing (CFF) Net Change in Cash = CFO + CFI + CFF
Three Sections of Cash Flow
Every cash movement falls into one of three buckets
Cash from Operations (CFO)
Cash generated by core business activities
Cash from Investing (CFI)
Cash spent or received from long-term assets
Cash from Financing (CFF)
Cash from or to capital providers (debt & equity)
$185M - $95M - $60M
+$30M
Net Income to CFO Bridge
Walk through each adjustment from Net Income to Cash from Operations
Starting point from the income statement
Non-cash expense — add back because no cash left the business
Non-cash expense — shares were issued, not cash
Revenue was recognized but cash wasn't collected yet
Cash was spent to buy inventory not yet sold
Expenses were incurred but cash hasn't been paid yet
Tax expense recognized on income statement but not yet paid

Without adjustments, CFO equals Net Income. Start toggling to see the indirect method in action.
Cash from Operations (CFO)
CFO starts with Net Income and adjusts for non-cash items (D&A, stock-based comp, deferred taxes) and changes in working capital. An increase in accounts receivable reduces cash (you recognized revenue but didn't collect). An increase in accounts payable increases cash (you incurred expenses but haven't paid). CFO is the most important section because it shows how much cash the core business generates independent of investments or financing decisions.
Cash from Investing (CFI)
CFI captures capital expenditures (CapEx), acquisitions, divestitures, and purchases/sales of investments. CapEx is almost always a cash outflow and is the largest item in this section for most companies. Acquisitions show up as a large negative in the quarter they close. For banks and analysts, CapEx is the key investing item because it is needed to calculate free cash flow (CFO minus CapEx).
Cash from Financing (CFF)
CFF includes debt issuances and repayments, equity issuances and buybacks, and dividend payments. A company raising $500M in a bond offering would show a $500M positive in CFF. Share buybacks appear as a negative. In leveraged buyouts, the financing section is crucial — it shows how the new capital structure is funded and how debt is subsequently repaid over the hold period.
Connecting Cash Flow to the Balance Sheet
The ending cash balance on the cash flow statement must equal the cash line on the balance sheet. This is the 'check' that proves your three-statement model balances. If your model doesn't balance, the error is almost always in the cash flow statement — typically a missed working capital adjustment or an incorrectly linked debt schedule. Interviewers know this, which is why 'How does a $10 depreciation increase flow through the three statements?' remains the most popular IB interview question.
Worked Example — With Real Numbers
Net Income $120M + D&A $50M + SBC $10M - Working Capital increase $15M = CFO $165M. CapEx -$60M = CFI -$60M. Debt repaid -$30M, Buybacks -$20M, Dividends -$10M = CFF -$60M. Net change in cash = $165M - $60M - $60M = $45M. Starting cash $50M + $45M = Ending cash $95M, which ties to the balance sheet.
Key Takeaways
Three sections: CFO (operations), CFI (investing), and CFF (financing) — CFO is the most important for measuring business health
D&A is added back in CFO because it reduced net income but no cash actually left the building
An increase in working capital (like AR going up) is a cash outflow even though it looks like revenue on the income statement
Ending cash on the cash flow statement must tie to cash on the balance sheet — this is the model balance check
Free cash flow (CFO minus CapEx) is the single best measure of how much cash a business truly generates
Common Mistakes in Interviews
Forgetting that working capital changes have the opposite sign you might expect — AR going up means cash going down
Confusing CapEx (cash flow statement) with depreciation (non-cash income statement charge) — they are related but different
Not understanding why stock-based comp is added back in CFO — it is a real cost to shareholders via dilution, but not a cash outflow
Mixing up the three sections: debt repayment is financing, not operations; buying a company is investing, not operations
How Interviewers Test This
The #1 interview question in banking: 'If depreciation goes up by $10, walk me through the three statements.' Start with the income statement (EBIT down $10, Net Income down $7.5 at 25% tax), then cash flow statement (Net Income down $7.5, D&A up $10, so CFO up $2.5), then balance sheet (PP&E down $10, Cash up $2.5, Retained Earnings down $7.5 — it balances).
