Basis Of Presentation and Significant Accounting Policies [Abstract]  
Principles of Consolidation
Principles of Consolidation
 
Our unaudited condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation of our financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of March 31, 2013 and the results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results to be expected for any future period.
 
Our unaudited condensed consolidated financial statements are prepared in accordance with GAAP. These accounting principles require us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We believe that the estimates, judgments and assumptions are reasonable, based on information available at the time they are made. Actual results could differ materially from those estimates.
Recent Accounting Pronouncements
In February 2013, the FASB issued ASU 2013-01, Balance Sheet (Topic 220): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which clarifies that ordinary trade receivables and receivables are not in the scope of ASU 2011-11. ASU 2011-11 applies only to derivatives, repurchase agreements and reverse purchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria contained in the Codification or subject to a master netting arrangement or similar agreement. The effective date is the same as the effective date of ASU 2011-11. Its adoption of ASU 2013-01 is not expected to have any material impact on its condensed consolidated financial statements.
 
In February 2013 the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The ASU requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified. This ASU is effective prospectively for reporting periods beginning after December 15, 2012. Its adoption of ASU 2013-02 is not expected to have any material impact on its condensed consolidated financial statements.
