5.3 Balance Sheets, Assets, Liabilities, and Equity

Balance Sheet Analysis: Assets, Liabilities, And Equity

The balance sheet (statement of financial position) is a point-in-time snapshot governed by the accounting identity: Assets = Liabilities + Equity. Assets are resources expected to provide future economic benefit; liabilities are present obligations expected to require future outflows; equity is the residual claim of owners after liabilities are deducted from assets.

The identity is simple, but interpretation is demanding. A high asset balance may reflect productive capacity, excess inventory, expensive acquisitions, or slow receivables. A low liability balance may reflect conservative financing, unused borrowing capacity, or underinvestment. Equity grows through retained earnings and share issuance and shrinks through losses, dividends, buybacks, and accumulated other comprehensive losses.

Classification and working capital

An item is current if it will be settled or converted within one year or the operating cycle, whichever is longer; otherwise it is noncurrent. Working capital = current assets − current liabilities. A positive figure suggests liquidity, but bigger is not always better: bloated inventory or receivables tie up cash and can flag operating weakness.

Assets = Liabilities + Equity
Working capital      = current assets - current liabilities
Current ratio        = current assets / current liabilities
Quick (acid-test)    = (cash + marketable securities + receivables) / current liabilities
Debt-to-equity       = total debt / total equity
Book value per share = common equity / common shares outstanding

For example, with current assets of 600 and current liabilities of 400, the current ratio is 1.50 and working capital is 200. The quick ratio is more conservative because it excludes inventory and prepaid items, which are the least liquid current assets.

Measurement bases and their limits

Measurement basis shapes analysis. Cash is near face value; receivables are net of an allowance for doubtful accounts; inventory uses FIFO, weighted average, or (US GAAP only) LIFO; PP&E is usually historical cost less accumulated depreciation, though IFRS permits a revaluation model for some classes; financial instruments are carried at fair value or amortized cost depending on classification.

These choices create gaps between book and economic value. A valuable internally generated brand is absent from the balance sheet, while purchased goodwill from an acquisition is recorded. Land bought decades ago may sit near historical cost. Liabilities for warranties, pensions, leases, or legal contingencies require estimates. Read the notes before treating any book value as an economic value.

Connections, common-size, and equity detail

Balance sheet accounts tie directly to the other statements: receivables link to revenue quality, inventory to COGS and gross margin, PP&E to depreciation, debt to interest expense, and deferred tax accounts to the gap between book and taxable income. A strong FSA answer traces a change in one statement through the others.

Common-size balance sheets express each account as a percentage of total assets, highlighting resource intensity: a manufacturer carries heavy PP&E and inventory, a software firm holds more cash and intangibles, and a bank is dominated by financial assets and liabilities, so industrial-style ratios can mislead.

Equity is more than ending common equity. Retained earnings are cumulative profits less dividends, not a cash reserve. Treasury stock is a contra-equity account for repurchased shares. AOCI holds gains and losses that bypassed net income. Noncontrolling interest is the share of a consolidated subsidiary owned by outside parties. Finally, off-balance-sheet exposures, purchase commitments, take-or-pay contracts, and guarantees may live only in the notes, so the balance sheet must be read alongside the notes and cash flow statement to gauge true liquidity and solvency.

Classifying investments in securities

A common Level I balance sheet topic is how a company carries its investments in the debt and equity of other firms, because the classification determines both the carrying value and where gains and losses appear. Three categories recur on the exam. Securities measured at fair value through profit or loss (held for trading) are marked to market each period, with unrealized gains and losses flowing through net income.

Debt securities measured at fair value through other comprehensive income (available-for-sale in older terminology) are marked to market, but the unrealized gains and losses sit in AOCI within equity rather than net income until realized. Debt held to collect contractual cash flows is measured at amortized cost, with no mark-to-market adjustment at all. The same bond can therefore appear at three different values and route its returns through three different places depending solely on classification, which is why analysts read the investment footnote before comparing two firms' equity or earnings.

A worked balance sheet identity check

Suppose a firm begins the year with assets of 1,000, liabilities of 600, and equity of 400. During the year it earns net income of 80, pays dividends of 30, and issues new shares for 50 in cash. Ending equity is 400 + 80 − 30 + 50 = 500, and ending assets must rise by the net cash and earnings effects so that the identity Assets = Liabilities + Equity still holds. If a question instead reports ending assets of 1,150 and ending liabilities of 600, the implied equity is 550, which would flag an inconsistency with the activity described and prompt the analyst to look for a missing item such as a buyback or an OCI movement.

The discipline of forcing every transaction back through the identity is the single most reliable balance sheet check on the exam, and it exposes plugged or erroneous figures quickly.
