The provision for income taxes is determined using the asset and liability approach. Under this approach, deferred income taxes represent the expected future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities. 3M records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists. As of December 31, 2018 and 2017, 3M had valuation allowances of $67 million and $81 million on its deferred tax assets, respectively. 3M recognizes and measures its uncertain tax positions based on the rules under ASC 740, Income Taxes.
