where some or all of the goodwill allocated to a particular cash-generating unit arose in respect of that combination, the cash-generating unit is tested for impairment prior to the end of the relevant annual period. 

Property, plant and equipment assets are reviewed for potential impairment by applying a series of external and internal indicators specific to the assets under consideration; these indicators encompass macroeconomic issues including the inherent cyclicality of the building materials sector, actual obsolescence or physical damage, a deterioration in forecast performance in the internal reporting cycle and restructuring and rationalisation programmes. 

Where the carrying value exceeds the estimated recoverable amount (being the greater of fair value less costs to sell and value-in-use), an impairment loss is recognised by writing down the assets to their recoverable amount. In assessing value-in-use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the future cash flow estimates have not been adjusted. The estimates of future cash flows exclude cash inflows or outflows attributable to financing activities and income tax. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined by reference to the cash-generating unit to which the asset belongs. Impairment losses arising in respect of goodwill are not reversed once recognised. 

Goodwill relating to associates is included in the carrying amount of the investment and is neither amortised nor individually tested for impairment. Where indicators of impairment of an investment arise in accordance with the requirements of IAS 39 Financial Instruments: Recognition and Measurement , the carrying amount is tested for impairment by comparing its recoverable amount with its carrying amount. 

The impairment testing process requires management to make significant judgements and estimates regarding the future cash flows expected to be generated by the use of and, if applicable, the eventual disposal of, long-lived assets and goodwill as well as other factors to determine the fair value of the assets. Management periodically evaluates and updates the estimates based on the conditions which influence these variables. A detailed discussion of the impairment methodology applied and key assumptions used by the Group in the context of long-lived assets and goodwill are provided in Notes 14 and 15 to the Consolidated Financial Statements. 

The assumptions and conditions for determining impairments of long-lived assets and goodwill reflect management’s best assumptions and estimates, but these items involve inherent uncertainties described above, many of which are not under management’s control. As a result, the accounting for such items could result in different estimates or amounts if management used different assumptions or if different conditions occur in future accounting periods. 

## Other Significant Accounting Policies 

## Basis of consolidation 

The Consolidated Financial Statements include the financial statements of the Parent Company and all subsidiaries, joint ventures and associates, drawn up to 31 December each year. The financial year-ends of the Group’s subsidiaries, joint ventures and associates are co-terminous. 

## Subsidiaries 

The financial statements of subsidiaries are included in the Consolidated Financial Statements from the date on which control over the operating and financial decisions is obtained and cease to be consolidated from the date on which the Group loses control. The existence and effect of potential voting rights that are currently exercisable or convertible are considered in determining the existence or otherwise of control. A change in the ownership interest of a subsidiary, without a change of control, is accounted for as an equity transaction. 

Non-controlling interests represent the portion of the equity of a subsidiary not attributable either directly or indirectly to the Parent Company and are presented separately in the Consolidated Income Statement and within equity in the Consolidated Balance Sheet, distinguished from Parent Company shareholders’ equity. Acquisitions of non-controlling interests are accounted for as transactions with equity holders in their capacity as equity holders and 

therefore no goodwill is recognised as a result of such transactions. On an acquisition by acquisition basis, the Group recognises any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. 

## Joint ventures – Note 2 

The Group’s share of results and net assets of joint ventures (jointly controlled entities which are entities in which the Group holds an interest on a long-term basis and which are jointly controlled by the Group and one or more other venturers under a contractual arrangement) are accounted for on the basis of proportionate consolidation from the date on which the contractual agreements stipulating joint control are finalised and are derecognised when joint control ceases. The Group combines its share of the joint ventures’ individual income and expenses, assets and liabilities and cash flows on a line-by-line basis with similar items in the Consolidated Financial Statements. 

Loans to joint ventures (after proportionate elimination) are classified as loans and receivables within financial assets and are recorded at amortised cost. 

## Associates – Note 10 

Entities other than subsidiaries and joint ventures in which the Group has a participating interest, and over whose operating and financial policies the Group is in a position to exercise significant influence, are accounted for as associates using the equity method and are included in the Consolidated Financial Statements from the date on which significant influence is deemed to arise until the date on which such influence ceases to exist. Under the equity method, the Consolidated Income Statement reflects the Group’s share of profit after tax of the related associates. Investments in associates are carried in the Consolidated Balance Sheet at cost adjusted in respect of post-acquisition changes in the Group’s share of net assets, less any impairment in value. If necessary, impairment losses on the carrying amount of an investment are reported within the Group’s share of associates’ profit after tax in the Consolidated Income Statement. If the Group’s share of losses exceeds the carrying amount of an associate, the carrying amount is reduced to nil and recognition of further losses is discontinued except to the extent that the Group has incurred obligations in respect of the associate. 

## Transactions eliminated on consolidation 

Intra-group balances and transactions, income and expenses, and any unrealised gains or losses arising from such transactions, are eliminated in preparing the Consolidated Financial Statements. Unrealised gains arising from transactions with joint ventures and associates are eliminated to the extent of the Group’s interest in the entity. Unrealised losses are eliminated in the same manner as unrealised gains, but only to the extent that there is no evidence of impairment in the Group’s interest in the entity. 

## Revenue recognition 

Revenue represents the value of goods and services supplied and is net of trade discounts and value added tax/sales tax. Other than in the case of construction contracts, revenue is recognised to the extent that revenue and related costs incurred or to be incurred are subject to reliable measurement, that it is probable that economic benefits will flow to the Group and that the significant risks and rewards of ownership have passed to the buyer, usually on delivery of the goods. 

## Construction contracts 

The Group engages primarily in the performance of fixed price contracts, as opposed to cost plus contracts, and recognises revenue in accordance with the percentage-of-completion method, with the completion percentage being computed generally by reference to the proportion that contract costs incurred at the balance sheet date bear to the total estimated costs of the contract. 

Contract costs are recognised as incurred. When the outcome of a construction contract can be estimated reliably and it is probable that the contract will be profitable, contract revenue is recognised over the period of the contract. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised only to the extent of contract costs incurred where it is probable that these costs will be recoverable. When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised immediately as an expense. Revenue and/or costs in respect of variations or contracts claims and incentive payments, to the extent that they arise, are recognised when it is probable that the amount, which can be measured reliably, will be recovered from/paid to the customer.
