Basis of Presentation (Policies) [Abstract]

Multiple-Deliverable Revenue Arrangements

Multiple-Deliverable Revenue Arrangements — In October 2009, the Financial Accounting Standards Board (“FASB”) amended authoritative guidance associated with multiple-deliverable revenue arrangements. This amended guidance addresses the determination of when individual deliverables within an arrangement are required to be treated as separate units of accounting and modifies the manner in which consideration is allocated across the separately identifiable deliverables. The amendments to authoritative guidance associated with multiple-deliverable revenue arrangements became effective for the Company on January 1, 2011. The new accounting standard has been applied prospectively to arrangements entered into or materially modified after the date of adoption. The adoption of this guidance has not had a material impact on our consolidated financial statements. However, our adoption of this guidance may significantly impact our accounting and reporting for future revenue arrangements to the extent they are material.

Reclassifications

Certain reclassifications have been made to our prior period consolidated financial information in order to conform to the current year presentation.

Fair Value Measurement

Fair Value Measurement — In May 2011, the FASB amended authoritative guidance associated with fair value measurements. This amended guidance defines certain requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles. The amendments to authoritative guidance associated with fair value measurements are effective for the Company on January 1, 2012 and are to be applied prospectively. We are in the process of assessing the provisions of this new guidance and currently do not expect that the adoption will have a material impact on our consolidated financial statements.
