Accounting Policies and Related Matters (Policies) [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six months ended June 30, 2011 are not necessarily an indication of the results that may be expected for the year ending December 31, 2011. For further information, refer to the financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2010, as updated by our Current Report on Form 8-K filed May 10, 2011.
New Accounting Standards	New Accounting Standards In April 2011, FASB issued ASU No. 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring (“TDR”). It intended to provide additional guidance to assist creditors in determining whether a restructuring of a receivable meets the criteria to be considered a troubled debt restructuring. The amendments in this ASU are effective for the first interim or annual period beginning on or after June 15, 2011, and are to be applied retrospectively to the beginning of the annual period of adoption. As a result of applying these amendments, an entity may identify receivables that are newly considered impaired. Early adoption is permitted. We are continuing to evaluate the impact of adoption of this ASU. In June 2011, the FASB issued Accounting Standards Update No. 2011-05, “Statement of Comprehensive Income” (“ASU 2011-05”), which requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 will only impact the company’s financial presentation as the company currently presents items of other comprehensive income in the statement of changes in equity. ASU 2011-05 will be effective for our fiscal year beginning January 1, 2012.
