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.
