Acquisition [Abstract]
Acquisition Policy	This transaction qualifies as a business combination for accounting purposes, therefore the assets acquired were recorded at their respective estimated fair values at the date of acquisition. The excess of the purchase price over those fair values is recorded as goodwill.

Disclosure of accounting policy for completed business combinations (purchase method, acquisition method or combination of entities under common control). This accounting policy may include a general discussion of the purchase method or acquisition method of accounting (including for example, the treatment accorded contingent consideration, the identification of assets and liabilities, the purchase price allocation process, how the fair values of acquired assets and liabilities are determined) and the entity's specific application thereof. An entity that acquires another entity in a leveraged buyout transaction generally discloses the accounting policy followed by the acquiring entity in determining the basis used to value its interest in the acquired entity, and the rationale for that accounting policy.
