Carlsberg Group Annual Report 2013 Consolidated financial statements SECTION 9: BASIS FOR PREPARATION 130 In preparing the Carlsberg Group’s consolidated  financial statements, management makes  various accounting estimates, judgements and  assumptions which form the basis of presenta- tion, recognition and measurement of the Group’s assets and liabilities.  The judgements, estimates and assumptions  made are based on historical experience and  other factors which management assesses  to be reliable, but which, by their very na- ture, are associated with uncertainty and un- predictability. These assumptions may prove  incomplete or incorrect, and unexpected  events or circumstances may arise.  The significant accounting estimates and  judgements made and the accounting pol- icies specific to the income statement, state- ment of financial position and statement of  cash flows are presented in the explanatory  notes in section 1-7: Business combinations:  SECTION 5 Impairment testing:  SECTION 2 Useful life and residual value of  intangible assets with finite useful life and property, plant and equipment:  SECTION 2 Restructurings : SECTION 3 Provisions and contingencies : SECTION 3 Receivables:  SECTION 1 Deferred tax assets:  SECTION 6 Retirement benefit obligations and similar obligations :  SECTION 7
