Business Combinations [Abstract]
Business Combinations Policy	Purchase Price Allocation In accordance with FASB ASC Topic 805, Business Combinations, the application of purchase accounting requires that the total purchase price be allocated to the fair value of assets acquired and liabilities assumed based on their fair values at the acquisition date, with amounts exceeding the fair values recorded as goodwill. If the fair value of the assets acquired and liabilities assumed exceeds the fair value of the consideration given, a bargain purchase has occurred which is recorded as a gain on acquisition. The allocation process requires, among other things, an analysis of acquired fixed assets, contracts and contingencies to identify and record the fair value of all assets acquired and liabilities assumed. We utilized a third-party appraiser to assist us in allocating the purchase price to the fair value of the assets acquired and liabilities assumed. Estimates of fair value are based on industry data and trends and by reference to relevant market rates and transactions, and discounted cash flow valuation methods, among other factors. The foregoing estimates and assumptions are inherently subject to significant uncertainties and contingencies beyond our reasonable control. The preliminary allocation of the fair value of the assets acquired is subject to additional adjustment to provide us with adequate time to complete the valuation of CVR's assets and liabilities.

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.
