Questions

What does EarningsPerShareBasic mean in XBRL?

us-gaap:EarningsPerShareBasic is the XBRL concept for “Earnings Per Share, Basic”. The taxonomy defines it as: The amount of net income (loss) for the period per each share of common stock or unit outstanding during the reporting period.

Why do two companies use different revenue concepts?

Companies choose the most specific concept for what they report. Since ASC 606 many use RevenueFromContractWithCustomerExcludingAssessedTax rather than Revenues, so a cross-company revenue series has to check several concepts.

Why can the same period appear in several filings?

Comparative periods are repeated in later reports and sometimes restated. companyfacts keeps every observation with its accession number; this page shows the most recently filed value per period.
