our exposure to risk is minimal given the nature of the investments .
our practice is to have our pension plan 100% ( 100 % ) funded at each year end on a projected benefit obligation basis , while also satisfying any minimum required contribution and obtaining the maximum tax deduction .
based on our actuarial projections , we estimate that a $ 14.1 million contribution in 2011 will allow us to meet our funding goal .
however , the amount of the actual contribution is contingent on the actual rate of return on our plan assets during 2011 and the december 31 , 2011 discount rate .
net current deferred tax assets of $ 18.3 million and $ 23.8 million are included in other current assets at december 31 , 2010 and 2009 , respectively .

net long-term deferred tax liabilities were $ 7.8 billion and $ 7.6 billion at december 31 , 2010 and 2009 , respectively .
net deferred tax liabilities are principally the result of purchase accounting for intangible assets in our various mergers including cbot holdings and nymex holdings .
we have a long-term deferred tax asset of $ 145.7 million included within our domestic long-term deferred tax liability .
this deferred tax asset is for an unrealized capital loss incurred in brazil related to our investment in bm&fbovespa .
as of december 31 , 2010 , we do not believe that we currently meet the more-likely-than-not threshold that would allow us to fully realize the value of the unrealized capital loss .
as a result , a partial valuation allowance of $ 64.4 million has been provided for the amount of the unrealized capital loss that exceeds potential capital gains that could be used to offset the capital loss in future periods .
we also have a long-term deferred tax asset related to brazilian taxes of $ 125.3 million for an unrealized capital loss incurred in brazil related to our investment in bm&fbovespa .
a full valuation allowance of $ 125.3 million has been provided because we do not believe that we currently meet the more-likely-than-not threshold that would allow us to realize the value of the unrealized capital loss in brazil in the future .
valuation allowances of $ 49.4 million have also been provided for additional unrealized capital losses on various other investments .
net long-term deferred tax assets also include a $ 19.3 million deferred tax asset for foreign net operating losses related to swapstream .
our assessment at december 31 , 2010 was that we did not currently meet the more-likely- than-not threshold that would allow us to realize the value of acquired and accumulated foreign net operating losses in the future .
as a result , the $ 19.3 million deferred tax assets arising from these net operating losses have been fully reserved .
