The component of income tax expense for the period representing the increase (decrease) in the entity's deferred tax assets and liabilities pertaining to continuing operations. This amount differs from the Cash Flow concept of the same name, thus an extended concept is needed. This amount is the actual tax expense associated with the corporation, while the Cash Flow provides the increase (decrease) of the deferred tax.
