Re-assessment of Unrecognised Deferred Tax Assets :

At each balance sheet date, an enterprise re-assesses unrecognised deferred tax assets. The enterprise recognises previously unrecognised deferred tax assets to the extent that it has become reasonably certain or virtually certain, as the case may be (see paragraphs 15 to 18), that sufficient future taxable income will be available against which such deferred tax assets can be realised. For example, an improvement in trading conditions may make it reasonably certain that the enterprise will be able to generate sufficient taxable income in the future.
