Disclosure of changes in accounting estimates [abstract]  
Consolidation Consolidation
The consolidated financial statements include information about the Company and its subsidiaries in which it held direct or indirect control. Control of a subsidiary is achieved when the Company is exposed, or has rights, to variable returns in such subsidiaries and has the power to influence the investee's operating and financial decisions.
The financial statements of the subsidiaries have been prepared using the same accounting policies as the Company.
All assets, liabilities, equity, income and expenses related to transactions between related parties are eliminated in full in the consolidation process.
Impairment Impairment
The Company performs an annual review for impairment indicators to assess events or changes in economic, technological, or operating conditions that may indicate that an asset is impaired.
The recoverable amount of an asset or cash-generating unit is the higher of its fair value, less costs to sell and its value in use. When the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, a provision for impairment loss is recognized by reduction the carrying amount.
The previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset's recoverable amount. The reversal is limited, so that the carrying amount of the asset does not exceed its recoverable amount, nor does it exceed the carrying amount previously determined, net of depreciation or amortization.
In estimating the asset's value in use, estimated future cash flows are discounted to present value, using a pre-tax discount rate that reflects the weighted average cost of capital.
