Two-year trends

Revenue

All the money the company took in from sales, before any costs.

Billions of dollars, as filed.

Net income

What was left after all costs, interest and taxes: the bottom line. Below the line is a loss.

Billions of dollars: net income attributable to the company's shareholders, as filed (GAAP).

Free cash flow

Cash brought in by running the business, minus spending on property and equipment. Below the line means the company spent more than it brought in that quarter.

Billions of dollars. Calculated by the Tribune: cash from operations minus payments for property and equipment, both as filed.

Shares outstanding

How many shares exist. When the number rises, each share owns a smaller slice of the company.

Billions of shares on each quarter-end date (or on the report's cover page a few weeks later).

Cash and short-term investments compared with debt

Cash on hand next to what the company owes in loans and bonds.

Cash and short-term investmentsDebt

Billions of dollars at each quarter-end. Debt = short-term plus long-term debt, only when both are filed for that date (calculated by the Tribune). A dash means no data.

Warning-sign checks

Code looks for these filings in the last three years and reports only that a filing exists, never what it means for the stock.

Auditor change

The company changed the accounting firm that checks its books.

None in the last three years

Past results can't be relied on

The company said earlier reported results were wrong and will be corrected.

None in the last three years

None in the last three years
