General Motors Co. (GM)

The liability method is used in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements using the statutory tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax laws or rates is recorded in the results of operations in the period that includes the enactment date under the law.

Deferred income tax assets are evaluated quarterly to determine if valuation allowances are required or should be adjusted. General Motors establishes valuation allowances for deferred tax assets based on a more likely than not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence factors. It is difficult to conclude a valuation allowance is not required when there is significant objective and verifiable negative evidence, such as cumulative losses in recent years. General Motors utilizes a rolling three years of actual and current year results as the primary measure of cumulative losses in recent years.

Income tax expense (benefit) for the year is allocated between continuing operations and other categories of income such as Other comprehensive income (loss). In periods in which there is a pre-tax loss from continuing operations and pre-tax income in another income category, the tax benefit allocated to continuing operations is determined by taking into account the pre-tax income of other categories.

General Motors records uncertain tax positions on the basis of a two-step process whereby General Motors determines whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position, and for those tax positions that meet the more likely than not criteria, General Motors recognizes the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority. General Motors records interest and penalties on uncertain tax positions in Income tax expense (benefit).
