About the metric
What total assets mean
Total assets are the resources a company controls at a reporting-period end, including cash, investments, receivables, inventory, property, intangible assets, and other reported assets. The composition of assets differs substantially by industry.
Calculation and source
SEC-reported total assets
TickerStat uses total assets reported in company SEC filings. When a filer provides the equivalent balance-sheet total as liabilities and equity, that reported amount is used because total assets must equal total liabilities plus equity. Fiscal periods can differ from calendar years, so exact period-end dates are included.
