Notes to Financial Statements [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2011, the Financial Accounting Standards Board ("FASB") issued a new accounting standard on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. We are required to adopt this standard in the third quarter of 2012. We do not expect this adoption to have a material impact on our financial statements. In June 2011, the FASB issued a new accounting standard on the presentation of comprehensive income. The new standard requires the presentation 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. We are required to adopt this standard as of the beginning of 2013. The new standard also required presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented, which was indefinitely deferred by an update issued by the FASB in December 2011. The adoption of these standards will only impact the presentation of our financial statements.
