Financial Statements
When to use
Use this to prepare or review the three primary financial statements for a period, confirm they articulate correctly, or produce a management reporting package with variance commentary.
Not for: decomposing a single variance into price/volume/mix drivers (fin-variance-analysis), building a forward cash forecast (fin-cash-flow — this uses the historical indirect-method statement), or reconciling underlying accounts (fin-reconciliation).
Method
- Set the reporting basis. State entity, period, currency, basis (GAAP / IFRS / management), and comparison columns (prior period, prior year, budget).
- Build the income statement. Revenue, COGS, gross profit, operating expenses by category, operating income, other income/expense, taxes, net income; compute margins.
- Build the balance sheet. Assets (current, non-current), liabilities (current, non-current), equity. Decision point: if assets ≠ liabilities + equity, stop — do not proceed to cash flow until it balances.
- Build the cash flow statement. Operating (indirect: net income + non-cash + working-capital changes), investing, financing; sum to net change in cash.
- Tie the statements together. Net income flows to retained earnings; ending cash equals the balance-sheet cash line; PP&E and debt roll forward.
- Run variance analysis. For each material line compute change vs comparison in $ and %; flag anything past the materiality threshold.
- Write commentary. Explain each flagged variance with its driver. Decision point: if a variance is material but you cannot name a driver, treat it as a possible error and re-check the ledger, not a story to invent.
Example
Q2, GAAP, vs prior quarter. P&L: revenue $4.2M, net income $610k. Balance sheet balances at $18.4M = $11.0M + $7.4M. Cash flow starts from $610k NI, adds $180k depreciation, subtracts $240k AR growth, nets to +$390k operating; ending cash $2.1M — matches the balance-sheet cash line (articulation pass). Variance: opex +$150k (+9%) vs Q1, flagged; driver = two Q2 sales hires. Retained earnings roll: opening $6.79M + $610k = $7.4M — ties.
Pitfalls
- Force-balancing with a plug. A "rounding" line hiding a real $30k gap masks a booking error — find it.
- Ending cash that doesn't match the balance sheet. If the cash-flow ending cash ≠ balance-sheet cash, the statements do not articulate; the package is wrong.
- Copying prior-period commentary. Stale narratives claim drivers that no longer apply — re-derive from this period's numbers.
- Flagging every line. Below-materiality noise buries the two variances leadership actually needs.

The three statements and how they articulate
The statements are one interlocking system. If any tie below fails, the package is wrong — do not issue it.
| Tie-out |
Rule |
| Net income → equity |
Beginning retained earnings + net income − dividends = ending retained earnings |
| Cash flow → balance sheet |
Ending cash on the cash-flow statement = cash line on the balance sheet |
| Balance sheet identity |
Assets = Liabilities + Equity (every period) |
| Depreciation |
On P&L (expense), added back on CFS (non-cash), and accumulated on BS (contra-asset) — same number in all three |
| PP&E roll-forward |
Beginning PP&E + capex − disposals − depreciation = ending PP&E |
| Debt roll-forward |
Beginning debt + draws − repayments = ending debt; interest on P&L, principal in financing |
| AR/AP → CFS |
Increase in AR = cash use (subtract); increase in AP = cash source (add) |
Indirect-method cash flow (operating section)
Net income + non-cash items (depreciation, amortization, stock comp, deferred tax, impairments) ± changes in working capital + gains/losses reversed = cash from operations. Working-capital sign rule: an increase in an asset (AR, inventory, prepaids) uses cash (subtract); an increase in a liability (AP, accrued, deferred revenue) provides cash (add). Investing = capex, acquisitions, asset sales, investments. Financing = debt draws/repayments, equity issuance/buybacks, dividends.

Statement structure checklist
- Income statement: Revenue → COGS → gross profit → operating expenses → operating income (EBIT) → other income/expense, interest → pre-tax income → tax → net income. Compute margins at each level.
- Balance sheet: current assets, non-current assets | current liabilities, non-current liabilities, equity. Order current items by liquidity.
- Cash flow: operating + investing + financing = net change in cash; + beginning cash = ending cash (which must match the BS).
Materiality and commentary
Set a materiality threshold before flux review (common: ≥5% and ≥ a dollar floor). Flag only lines past it; below-threshold noise buries the real story. Every flagged variance needs a named driver derived from this period's data — a material variance with no explainable driver is a suspected error; re-check the ledger rather than invent a narrative. Never force-balance with a plug; a "rounding" line hiding a real gap is a booking error waiting to be found. GAAP vs IFRS differences that affect statements: inventory (IFRS bans LIFO), development costs (IFRS may capitalize), asset revaluation (IFRS permits), and lease/impairment mechanics — state the basis up front.
