comcast corporation changes in our net deferred tax liability in 2015 that were not recorded as deferred income tax expense are primarily related to decreases of $ 28 million associated with items included in other comprehensive income ( loss ) and decreases of $ 132 million related to acquisitions made in 2015 .
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 .
as of december 31 , 2015 , we had federal net operating loss carryforwards of $ 135 million and various state net operating loss carryforwards that expire in periods through 2035 .
as of december 31 , 2015 , we also had foreign net operating loss carryforwards of $ 700 million that are related to the foreign operations of nbcuni- versal , the majority of which expire in periods through 2025 .
the determination of the realization of the state and foreign net operating loss carryforwards is dependent on our subsidiaries 2019 taxable income or loss , appor- tionment percentages , and state and foreign laws that can change from year to year and impact the amount 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 .

uncertain tax positions our uncertain tax positions as of december 31 , 2015 totaled $ 1.1 billion , which exclude the federal benefits on state tax positions that were recorded as deferred income taxes .
included in our uncertain tax positions was $ 220 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 our uncertain tax positions in the future , $ 592 million 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 completion of examinations of our tax filings by the various tax authorities and the expiration of statutes of limitations .
in 2014 , we reduced our accruals for uncertain tax positions and the related accrued interest on these tax positions and , as a result , our income tax expense decreased by $ 759 million .
it is reasonably possible that certain tax contests could be resolved within the next 12 months that may result in a decrease in our effective tax rate .
