Recent Accounting Pronouncements [Abstract]
Presentation Of Comprehensive Income	Presentation of Comprehensive Income In June 2011, the FASB issued guidance that requires an entity to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements.  The option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity has been eliminated.  This guidance became effective in the first quarter of 2012.  Our presentation of comprehensive income already complies with this new guidance.
