The discrete item in the six month period ended June 30, 2020 was primarily related to the tax impact of the divestiture of VNBS. Veoneer's effective tax rate differs from an expected statutory rate primarily due to the discrete item and losses in certain jurisdictions that are not benefited.Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
