Valuation Allowance Deferred Tax Asset Explanation of Change	The net deferred tax assets are included as components of Current and Non-Current Deferred Income Taxes and Accrued Liabilities within the Consolidated Balance Sheet. Our net deferred tax asset of $863 million consists of $305 million related to non-U.S. operations which are comprised principally of net deductible temporary differences and net operating loss, capital loss and tax credit carryforwards (mainly in Canada and the United Kingdom). We maintain a valuation allowance of $557 million against a portion of the non-U.S. gross deferred tax assets. Our valuation allowance decreased by $54 million in 2014, increased by $16 million in 2013 and increased by $7 million in 2012. The amount of the change in the valuation allowance that was credited to income tax expense for 2014 was $10 million and the amounts charged to income tax expense for 2013 and 2012 were $49 million and $18 million, respectively. In the event we determine that we will not be able to realize our net deferred tax assets in the future, we will reduce such amounts through a charge to income in the period such determination is made. Conversely, if we determine that we will be able to realize net deferred tax assets in excess of the carrying amounts, we will decrease the recorded valuation allowance through a credit to income tax expense in the period that such determination is made.
