We base our provision for income taxes on our current period income, changes in our deferred income tax assets and liabilities, income tax rates, changes in estimates of our uncertain tax positions, and tax planning opportunities available in the jurisdictions in which we operate. We recognize deferred tax assets and liabilities when there are temporary differences between the financial reporting basis and tax basis of our assets and liabilities and for the expected benefits of using net operating loss carryforwards. When a change in the tax rate or tax law has an impact on deferred taxes, we apply the change based on the years in which the temporary differences are expected to reverse. We record the change in our consolidated financial statements i n the period of enactment. Income tax consequences that arise in connection with a business combination include identifying the tax basis of assets and liabilities acquired and any contingencies associated with uncertain tax positions assumed or resulting from the business combination. Deferred tax assets and liabilities related to temporary differences of an acquired entity are recorded as of the date of the business combination and are based on our estimate of the ultimate tax basis that will be accepted by the various taxing authorities. We record liabilities for contingencies associated with prior tax returns filed by the acquired entity based on criteria set forth in the appropriate accounting guidance. We adjust the deferred tax accounts and the liabi lities periodically to reflect any revised estimated tax basis and any estimated settlements with the various taxing authorities. The effects of these adjustments are recorded to income tax expense. From time to time, we engage in transactions in which the tax consequences may be subject to uncertainty. In these cases, we evaluate our tax positions using the recognition threshold and the measurement attribute in accordance with the accounting guidance related to uncertain tax positions. Examples of these tr ansactions include business acquisitions and dispositions, including consideration paid or received in connection with these transactions, certain financing transactions, and the allocation of income among state and local taxing jurisdictions. Significant judgment is required in assessing and estimating the tax consequences of these transactions. We determine whether it is more likely than not that a tax position will be sustained on examination, including the resolution of any related appeals or litigation processes, based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in our consolidated financial statements. We classify intere st and penalties, if any, associated with our uncertain tax positions as a component of income tax expense. NBCUniversal For U.S. federal income tax purposes, NBCUniversal Holdings is treated as a partnership and NBCUniversal is disregarded as an entity se parate from NBCUniversal Holdings. Accordingly, neither NBCUniversal Holdings nor NBCUniversal and its subsidiaries incur any material current or deferred domestic income taxes. Following the close of the NBCUniversal r edemption t ransaction in March 2013, the taxable income of NBCUniversal Holdings and NBCUniversal is allocable entirely to us. We are indemnified by GE for any income tax liability attributable to the NBCUniversal contributed businesses for periods prior to the close of the NBCUniversal tran saction and also for any income tax liability attributable to NBCUniversal Enterprise for periods prior to the date of the NBCUniversal r edemption t ransaction. We ha ve indemnified GE for any income tax liability attributable to the businesses we contribute d to NBCUniversal for periods prior to the close of the NBCUniversal transaction. Current and deferred foreign income taxes are incurred by NBCUniversal’s foreign subsidiaries. In 2014, 2013 and 2012, NBCUniversal had foreign income before taxes of $385 million, $524 million and $434 million, respectively, on which foreign income tax expense was recorded. We recorded U.S. income tax expense on our allocable share of NBCUniversal’s income before domestic and foreign taxes, which was reduced by a U.S. tax credit equal to our allocable share of NBCUniversal’s foreign income tax expense.
Components of Net Deferred Tax Liability
December 31 (in millions) |  | 2014 |  | 2013
Deferred Tax Assets: |  |  |  |
| Net operating loss carryforwards | $ | 448 | $ | 495
| Differences between book and tax basis of long-term debt |  | 116 |  | 117
| Nondeductible accruals and other |  | 3,383 |  | 3,588
| Less: Valuation allowance |  | 375 |  | 405
|  |  |  | 3,572 |  | 3,795
Deferred Tax Liabilities: |  |  |  |
| Differences between book and tax basis of property and equipment and intangible assets |  | 35,112 |  | 34,044
| Differences between book and tax basis of investments |  | 186 |  | 473
| Differences between book and tax basis of indexed debt securities |  | 534 |  | 610
| Differences between book and tax basis of foreign |  |  |  |
|  | subsidiaries and undistributed foreign earnings |  | 504 |  | 367
|  |  | 36,336 |  | 35,494
Net deferred tax liability | $ | 32,764 | $ | 31,699
Changes in net deferred income tax liabilities in 2014 that were not recorded as deferred income tax expense are primarily related to decreases of $127 m illion associated with items included in other comprehensive income (loss) and increases of $26 million related to acquisitions made in 2014. Our net deferred tax liability includes $23 billion related to cable franchise rights that will remain unchanged unless we recognize an impairment or dispose of a cable franchise. Following the NBCUniversal re demption transaction, we recognized an increase in our deferred tax liabilities of $1.6 billion primarily due to an increase in our financial reporting basis in the consolidated net assets of NBCUniversal Holdings in excess of the tax basis. Net deferred t ax assets included in other current assets are primarily related to our current investments and current liabilities. As of December 31, 2014, we had federal net operating loss carryforwards of $127 million and various state net operating loss carryforwards that expire in periods through 203 4. As of December 31, 2014, we also had foreign net operating loss carryforwards of $331 million that are related to the foreign operations of NBCUniversal, the majority of which expire in periods through 202 4. The determination of the realization of the state and foreign net operating loss carryforwards is dependent on our subsidiaries’ taxable income or loss, apportionment percentages, and state and foreign laws that can change from year to year and impact the amou nt of such carryforwards. We recognize a valuation allowance if we determine it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. As of December 31, 2014 and 2013, our valuation allowance was primaril y related to state and foreign ne t operating loss carryforwards. Uncertain Tax Positions Our uncertain tax positions as of December 31, 2014 totaled $1.2 billion, which excludes the federal benefits on state tax positions tha t were recorded as deferred income taxes. I nclud ed in our uncertain tax positions was $243 million related to tax positions of NBCUniversal and NBCUniversal Enterprise for which we have been indemnified by GE. If we were to recognize the tax benefit for ou r uncertain tax positions in the future, $603 m illion would impact our effective tax rate and the remaining amount would increase our deferred income tax liability. The amount and timing of the recognition of any such tax benefit is dependent on the comple tion of examinations of our tax filings and the expiration of statutes of limitations. In September 2014, we reduced our accruals for uncertain tax positions and the related accrued interest on these tax positions. The reduction resulted in a decrease of $724 million in income tax expense, which excludes the benefits of uncertain tax positions for which we have been indemnified.

We are a limited liability company, and our company is disregarded for U.S. federal income tax purposes as an entity separate from NBCUniversal Holdings, a tax partnership. NBCUniversal and our subsidiaries are not expected to incur any significant current or deferred U.S. domestic income taxes. Our tax liability is comprised primarily of withholding tax on foreign licensing activity and income taxes on foreign earnings. As a result of o ur tax status, the deferred tax assets and liabilities included in our consolidated ba lance sheet at December 31, 2014 and 2013 were not material. In jurisdictions in which we are subject to income taxes, we base our provision for income taxes on our current period income, changes in our deferred income tax assets and liabilities, income tax rates, changes in estimates of our uncertain tax positions, and tax planning opportunities available in the jurisdictions in which we operate. We recognize def erred tax assets and liabilities when there are temporary differences between the financial reporting basis and tax basis of our assets and liabilities and for the expected benefits of using net operating loss carryforwards. When a change in the tax rate o r tax law has an impact on deferred taxes, we apply the change based on the years in which the temporary differences are expected to reverse. We record the change in our consolidated financial statements in the period of enactment. We classify interest an d penalties, if any, associated with our uncertain tax positions as a component of income tax expense. Uncertain Tax Positions We retain liabilities for uncertain tax positions where we are the tax filer of record. GE and Comcast have indemnified NBCUniver sal Holdings and u s with respect to our income tax obligations attributable to periods prior to the close of the joint venture transaction, including indemnification of uncertain tax positions for these periods. T he liabilities for uncertain tax po sitions included in our consolidated balanc e sheet were not material as of December 31, 2014 and 2013. Various domestic and foreign taxing authorities are examining our tax returns through 201 2. The majority of the periods under examination relate to tax years 2004 and forward.
