Accounting Changes And Error Corrections [Abstract]
Other comprehensive income	In February 2013, the Financial Accounting Standards Board (“FASB”) issued guidance that requires an entity to provide information about amounts it reclassifies out of accumulated other comprehensive income. If GAAP requires an entity to reclassify amounts out of accumulated other comprehensive income to net income in their entirety in the same reporting period, the guidance requires an entity to present significant amounts it reclassifies out of accumulated other comprehensive income by the respective line items of net income, either on the face of the statement where the entity presents net income or in the notes to the entity’s financial statements,. For other amounts that GAAP does not require an entity to reclassify to net income in their entirety, the guidance requires an entity to cross-reference such amounts to other disclosures GAAP requires that provide additional detail about those amounts. The guidance is effective for interim and annual reporting periods after December 15, 2012. We adopted this new guidance as of January 1, 2013. Our adoption of this new guidance did not impact our financial position, results of operations or cash flows. In July 2013, the FASB issued a new standard that requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss carryforward or similar tax loss or tax credit carryforward, rather than as a liability, when the uncertain tax position would reduce the net operating loss or other carryforward under the tax law of the applicable jurisdiction and when the entity intends to use the deferred tax asset for that purpose. The new standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this new standard in 2014 will not impact our financial position, results of operations or cash flows.
