Understand what a company owns versus what it owes, and the key ratios that measure financial strength and leverage.
In this lesson you'll learn
The accounting equation: Assets = Liabilities + Equity
The difference between current and non-current assets/liabilities
What shareholders' equity represents
Key ratios: current ratio, quick ratio, and debt-to-equity
The balance sheet in one sentence
The balance sheet answers: What does the company own, and how did it pay for it? Unlike the income statement (which covers a period), the balance sheet is a snapshot taken at a single point in time — usually the last day of the quarter.
It's built on one unbreakable equation:
Assets = Liabilities + Shareholders' Equity
Everything the company owns (assets) was paid for either by borrowing (liabilities) or by owners (equity). The two sides must always balance.
Assets: what the company owns
Assets are divided into current (convertible to cash within 12 months) and non-current (longer-term holdings).
Current Assets
Cash & equivalents
The most liquid — money in the bank and short-term investments
Accounts receivable
Money customers owe the company for goods/services already delivered
Inventory
Products manufactured or purchased, waiting to be sold
Prepaid expenses
Bills paid in advance (e.g., annual insurance premium)
Non-Current Assets
Property, plant & equipment (PP&E)
Factories, offices, machinery — depreciated over time
Intangible assets
Patents, trademarks, brand value — often the most valuable for tech companies
Goodwill
Premium paid over book value in acquisitions — a key scrutiny item
Long-term investments
Stakes in other companies, bonds held to maturity
Liabilities: what the company owes
Liabilities are also split into current (due within 12 months) and long-term obligations.
Current Liabilities
Accounts payable
Money the company owes its suppliers for goods already received
Short-term debt
Loans or bonds maturing within 12 months
Accrued liabilities
Expenses incurred but not yet paid (e.g., wages, taxes)
Deferred revenue
Cash received for services not yet delivered (e.g., annual subscriptions)
Long-Term Liabilities
Long-term debt
Bonds, loans, and notes payable beyond 12 months — the main leverage lever
Deferred tax liabilities
Taxes owed but deferred to future periods
Pension obligations
Future benefit payments promised to employees
Operating lease liabilities
Present value of future lease payments (e.g., office space)
Shareholders' equity: what owners are left with
Shareholders' equity is the residual interest — what would theoretically be left for shareholders if the company sold all its assets and paid all its debts. It consists of:
Common stock & additional paid-in capital
Money raised by selling shares to investors, including at IPO
Retained earnings
Cumulative profits kept in the business rather than paid as dividends — grows each year profits exceed dividends
Treasury stock (negative)
Shares the company has bought back from the market — reduces equity
Accumulated other comprehensive income
Unrealized gains/losses on certain investments and currency translations
Some companies — especially those that have aggressively bought back shares — have negative shareholders' equity. This isn't automatically bad (it can signal a mature, highly profitable business returning capital), but it does make standard ratio analysis less meaningful.
Key balance sheet ratios
Current Ratio
Current Assets ÷ Current Liabilities
Above 1.5: generally healthy. Below 1.0: may struggle to meet short-term obligations.
Quick Ratio
(Cash + Receivables) ÷ Current Liabilities
Strips out inventory (less liquid). A tougher liquidity test. Above 1.0 is ideal.
Debt-to-Equity (D/E)
Total Debt ÷ Shareholders' Equity
Under 1.0: conservative. 1–2: moderate. Above 2: highly leveraged — more financial risk.
Book Value Per Share
Shareholders' Equity ÷ Shares Outstanding
Used to calculate P/B ratio. A stock trading below book value may be undervalued — or in trouble.

A company has $2B in current assets and $800M in current liabilities. What is its current ratio, and what does it mean?
3
What does a high debt-to-equity (D/E) ratio tell you?
✓ Key takeaways from Lesson 3
Assets = Liabilities + Equity — this equation always holds.
Current assets/liabilities are short-term (≤12 months); non-current are longer-term.
Shareholders' equity is what owners would receive after paying all debts.
Current ratio measures short-term liquidity; D/E ratio measures leverage and financial risk.
