Organization, Consolidation and Presentation of Financial Statements [Abstract]
Revenue Recognition, Policy	In September 2009, new accounting guidance under ASC Topic 605 related to revenue arrangements with multiple deliverables was issued. The guidance addresses the unit of accounting for arrangements involving multiple deliverables, how arrangement consideration should be allocated to the separate units of accounting and eliminates the criterion that objective and reliable evidence of fair value of any undelivered items must exist for the delivered item to be considered a separate unit of accounting. Effective January 1, 2011, the Company prospectively adopted this standard for revenue arrangements entered into or materially modified after the adoption date. The adoption of this accounting standard did not have a material impact on the Company’s financial statements. In September 2009, new accounting guidance under ASC Topic 605 was issued regarding tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. Effective January 1, 2011, the Company prospectively adopted this standard for revenue arrangements entered into or materially modified after the adoption date. The adoption of this accounting standard did not have a material impact on the Company’s financial statements.
Income Tax, Policy	The Company’s income tax provision for interim periods is determined through the use of an estimated annual effective tax rate applied to year-to-date ordinary income, as well as the tax effects associated with discrete items.
Use of Estimates, Policy	Preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates. In the normal course of business, the Company is subject to various regulatory and tax proceedings, lawsuits, claims, and other matters. The Company believes adequate provision has been made for all such asserted and unasserted claims in accordance with U.S. GAAP. Such matters are subject to many uncertainties and outcomes that are not predictable with assurance.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
