Accounting Changes and Error Corrections [Abstract]  
Adoption of New Accounting Standards
In February 2013, the FASB issued an accounting standards update that adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. This update requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source (e.g., the release due to cash flow hedges from interest rate contracts) and the income statement line items affected by the reclassification (e.g., interest income or interest expense). If a component is not required to be reclassified to net income in its entirety (e.g., the net periodic pension cost), companies would instead cross reference to the related footnote for additional information (e.g., the pension footnote). This update was effective for us beginning in the first quarter of 2013, and we have included the applicable disclosures in note 10.
Other accounting pronouncements adopted during the periods covered by the consolidated financial statements had an immaterial impact on our consolidated financial position and results of operations.
Accounting Standards Issued But Not Yet Effective
Accounting pronouncements issued, but not effective until after March 31, 2013, are not expected to have a significant impact on our consolidated financial position or results of operations.
