Effective tax rate
Income tax expense divided by pretax income; unavailable when pretax income is zero or negative.
How it is calculated
Calculated as tax_expense / pretax_income, from Income tax expense, Pretax income. A figure the company reported directly always outranks this calculation, and it is withheld when its inputs come from different filing vintages.
