The Connection of the Three Financial Statements

How the Three Statements Form a Single Picture
The Balance Sheet, Income Statement (P&L), and Cash Flow Statement are not isolated documents, but an interconnected system. Understanding the relationships among them is critically important for financial modeling, analysis, and valuation.

Main Connections Between the Statements

Net Income → Retained Earnings: Net income from the P&L increases retained earnings on the balance sheet (minus dividends).
Retained Earnings (end) = Retained Earnings (begin) + Net Income - Dividends.

Net Income → Cash Flow Statement: Net Income is the starting point for calculating Operating Cash Flow using the indirect method. The CFS explains why profit is not equal to the change in cash.

Cash → Balance Sheet: The ending Cash on the CFS matches the Cash on the balance sheet at period end. The CFS is the “bridge” between beginning and ending Cash.

Depreciation: Linking All Three

Depreciation expense is reflected in the P&L (reducing Operating Income and Net Income).
On the balance sheet, Accumulated Depreciation increases, reducing Net PP&E.
In the CFS, Depreciation is added back to Net Income (a non-cash expense)—it does not affect CFO.

Example: Depreciation = $100.
P&L: Operating Expenses +$100, Net Income -$100 (pre-tax).
Balance Sheet: Accumulated Depreciation +$100, Net PP&E -$100.
CFS: Net Income -$100, Add back Depreciation +$100, CFO effect = $0 (as it should be—no cash flow).

CAPEX: Linking the Balance Sheet and CFS

Capital Expenditure (CAPEX) is the purchase of fixed assets.
It is reflected as an outflow in CFI (Investing Activities).
On the balance sheet, it increases Gross PP&E.
It does not affect the P&L at the time of purchase—the expense is recognized through amortization/depreciation in future periods.

PP&E Connection:
Net PP&E (end) = Net PP&E (begin) + CAPEX - Depreciation - Disposals.
CAPEX from the CFS and Depreciation from the P&L are linked to changes in PP&E on the balance sheet.

Changes in Working Capital

Accounts Receivable: If AR increases—the company has recognized revenue (P&L), but not yet received the cash.
In the CFS: An increase in AR is subtracted from Net Income when calculating CFO.
On the balance sheet: AR increases.

Inventory: If Inventory increases—the company has purchased/produced inventory but has not sold it. COGS in the P&L reflects only sold goods.
In the CFS: An increase in Inventory is subtracted (cash outflow for the purchase).
On the balance sheet: Inventory grows.

Accounts Payable: If AP increases—the company received a good/service (reflected in COGS/OpEx), but has not yet paid.
In the CFS: An increase in AP is added (cash preserved).
On the balance sheet: AP grows.
This is “free” financing from suppliers.

Debt: P&L, CFS, and Balance Sheet

Interest Expense: Reflected in the P&L, decreasing Net Income.
In the CFS, interest is usually part of CFO (though under IFRS, it may appear in CFF).
The debt principal itself is on the balance sheet.

Debt Issuance/Repayment: Shown in CFF (inflow upon receiving, outflow upon repayment).
On the balance sheet: change in Debt.
Does not affect the P&L (except interest expense).

Equity Transactions

Stock Issuance: Inflow in CFF.
On the balance sheet: Increases Common Stock and/or Additional Paid-in Capital.
Does not affect the P&L.

Share Repurchases: Outflow in CFF.
On the balance sheet: Increases Treasury Stock (contra-equity, reduces total equity).
Does not directly affect P&L (but impacts EPS by reducing shares outstanding).

Dividends: Outflow in CFF.
On the balance sheet: Reduces Retained Earnings.
Does not affect P&L (dividends are profit distribution, not an expense).

Building an Integrated Financial Model

Financial modeling begins with a forecast of the P&L (revenue growth, margins).
Based on the P&L, the CFS is forecasted (adjustments, working capital, CAPEX).
The CFS determines cash and the financing structure.
The balance sheet is balanced (Assets = Liabilities + Equity)—if it does not balance, there is a model error.

The "Plug" in the Model: Usually Cash or Revolver (credit line) serves as the balancing item.
If the model shows a surplus—Cash accumulates; deficit—Revolver is drawn. This ensures balance.

Practical Examples of Linkages

Example: A company sells a product for $100 on credit.
P&L: Revenue +$100, COGS -$60, Gross Profit +$40.
Balance Sheet: AR +$100, Inventory -$60.
CFS (indirect): Net Income +$40, AR increase -$100, Inventory decrease +$60, CFO = $0 (no cash flow—all on credit).

When the customer pays:
P&L: no effect (revenue already recognized).
Balance Sheet: Cash +$100, AR -$100.
CFS: AR decrease +$100 is added to CFO. The connection is restored.

Red Flags in the Connections

If Net Income consistently > CFO: receivables or other accruals are accumulating. Possible aggressive revenue recognition.

If CAPEX

If Debt grows but there is no growth in assets or returns to shareholders: where is the money going? Possibly operational losses are being financed—a red flag.
