Key concepts (hints)

Income statement · a whole year

Revenue (net sales)
What the company earns from selling goods and services, recorded when earned.
Cost of sales (cost of goods sold, merchandise costs)
The cost of the inventory that was sold. It leaves the balance sheet and becomes an expense.
Operating expenses (SG&A)
Costs of running the business other than the goods: wages, rent, utilities, advertising.
Depreciation
The part of a building’s or equipment’s cost recorded as an expense each year as it is used up. No cash is paid when it is recorded.
Income tax expense (provision)
The government’s share of the profit.
Net income
Revenue minus all expenses, including interest and taxes.

Statement of retained earnings

Retained earnings
Profit earned since the start and kept in the business. Beginning + Net income − Dividends = Ending.
Dividends
Profit paid out to shareholders. Not an expense.

Balance sheet · one date

Assets = Liabilities + Equity
Everything the company owns is financed by creditors or by owners.
Current assets / current liabilities
Expected to be used up or paid within one year.
Accounts receivable
Amounts customers owe the company, expected to be collected in cash.
Inventory
Goods held for sale, recorded at cost until sold.
Accumulated depreciation
All depreciation recorded so far on buildings and equipment. Cost − accumulated depreciation = net (book value).
Accounts payable
Amounts owed to suppliers for goods or services bought on credit.
Long-term debt
Money borrowed (loans, bonds) that is due after more than one year.

Finally, calculate (use the numbers on the front)

13Gross profit margin
= (Net sales − Cost of sales) ÷ Net sales
14Net profit margin
= Net income ÷ Total revenue
15Current ratio
= Total current assets ÷ Total current liabilities
13: (269,912 − 239,886) ÷ 269,912 = 11.1%  ·  14: 8,099 ÷ 275,235 = 2.9%  ·  15: 38,380 ÷ 37,108 = 1.03.
Costco keeps about 3 cents of every sales dollar as profit, and only about 11 cents after paying for the goods: it makes much of its profit from membership fees.

Some lines are combined. “Interest and other income, net” = interest income and other minus interest expense. Property and equipment at cost = net + accumulated depreciation. Costco reports its allowance on receivables as immaterial.
