Our foreign tax expense is disproportionately high, since no tax benefit can be realized on foreign losses subject to valuation allowances.Undistributed earnings of foreign subsidiaries were $527 million at October 31, 2011. Domestic income taxes have not been provided on these undistributed earnings because they are considered to be permanently invested in foreign subsidiaries. It is not practicable to estimate the amount of unrecognized deferred tax liabilities, if any, for these undistributed foreign earnings. The components of the deferred tax asset (liability) at October 31 are as follows:   2011 2010(in millions)    Deferred tax assets attributable to:    Employee benefits liabilities $1,369 $840Net operating loss (“NOL”) carry forwards 273 306Product liability and warranty accruals 262 232Research and development 74 98Tax credit carry forwards 208 115Other 294 335Gross deferred tax assets 2,480 1,926Less: Valuation allowances (344) (1,777)Net deferred tax assets $2,136 $149Deferred tax liabilities attributable to:    Goodwill and intangibles assets $(107) $(104)Other (39) (59)Total deferred tax liabilities $(146) $(163)At October 31, 2011, deferred tax assets attributable to NOL carry forwards include $126 million attributable to U.S. federal NOL carry forwards, $79 million attributable to state NOL carry forwards, and $102 million attributable to foreign NOL carry forwards. If not used to reduce future taxable income, U.S. federal NOLs are scheduled to expire beginning in 2025.  State NOLs can be carried forward for initial periods of 5 to 20 years, and are scheduled to expire in 2012 to 2031.  Approximately one half of our foreign net operating losses will expire beginning in 2029, while the balance has no expiration date.There are $34 million of NOL carry forwards relating to stock option tax benefits which are deferred until utilization of our net operating losses. These tax benefits will be allocated to Additional paid-in capital when recognized. The majority of our tax credits can be carried forward for initial periods of 20 years, and are scheduled to expire in 2012 to 2032.  Alternative minimum tax credits can be carried forward indefinitely. A valuation allowance is required to be established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The guidance on accounting for income taxes provides important factors in determining whether a deferred tax asset will be realized, including whether there has been sufficient taxable income in recent years and whether sufficient income can reasonably be expected in future years in order to utilize the deferred tax asset. We have evaluated the need to maintain a valuation allowance for deferred tax assets based on our assessment of whether it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. In 2011, this evaluation resulted in the determination that a significant portion of our valuation allowance on U.S. deferred tax assets could be released. The qualitative and quantitative analysis of current and expected domestic earnings, industry volumes, tax planning strategies, and general business risks resulted in a more likely than not conclusion of being able to realize a significant portion of our U.S. deferred tax assets.  We have been able to sustain positive cumulative earnings despite record low industry volumes during the current and previous three years. Industry volumes have increased during the year and the increase in volume is expected to continue in the foreseeable future. In addition, we have successfully diversified our business offerings and customer base to be less dependent on the traditionally cyclical truck industry. We continue to maintain a valuation allowance on certain federal, state, and foreign (principally Canada) deferred tax assets that we believe, on a more likely than not basis, will not be realized. We believe that it is more likely than not that the remaining deferred tax assets will be realized. Total deferred tax asset valuation allowances decreased by $1.5 billion in 2011 from $1.8 billion to $344 million. In the event we released all of our remaining valuation allowances, $4 million of tax benefits would be directly allocated to Additional paid in capital, the remainder would impact tax expense.  As of October 31, 2011 and 2010, the net amount of liability for uncertain tax positions was $19 million and $91 million, respectively. If these unrecognized tax benefits are recognized, all but $4 million would impact our effective tax rate. Changes in the liability for uncertain tax positions during the year ended October 31, 2011 are summarized as follows: (in millions)  Liability for uncertain tax positions at October 31, 2010 $91Increase as a result of positions taken in prior periods 79Decrease as a result of positions taken in prior periods (150)Increase as a result of positions taken in the current period 1Settlements (2)Liability for uncertain tax positions at October 31, 2011 $19We recognize interest and penalties as part of Income tax benefit (expense). Total interest and penalties related to our uncertain tax positions are immaterial. We have open tax years from 2005 to 2011 with various significant taxing jurisdictions including the U.S., Canada, Mexico, and Brazil. In connection with examinations of tax returns, contingencies may arise that generally result from differing interpretations of applicable tax laws and regulations as they relate to the amount, timing, or inclusion of revenues or expenses in taxable income, or the sustainability of tax credits to reduce income taxes payable. We believe we have sufficient accruals for our contingent tax liabilities. Annual tax provisions include amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns, although actual results may differ. While it is probable that the liability for unrecognized tax benefits may increase or decrease during the next twelve months, we do not expect any such change would have a material effect on our financial condition, results of operations, or cash flows. |
