Income Taxes implements a so-called 'comprehensive balance sheet method' of accounting for income taxes which recognises both the current tax consequences of transactions and events and the future tax consequences of the future recovery or settlement of the carrying amount of an entity's assets and liabilities. Differences between the carrying amount and tax base of assets and liabilities, and carried forward tax losses and credits, are recognised, with limited exceptions, as deferred tax liabilities or deferred tax assets, with the latter also being subject to a 'probable profits' test.
