In country Z, Valquessa (deferred tax liability 500,000) and Wenlandor (deferred tax asset 180,000), separate taxable entities, settle their tax net under a group regime which, under the tax law in the case, will end after 20X7. Reversals of Wenlandor's asset are expected in 20X6 and 20X9, those of Valquessa's liability in 20X8 and 20X9. How should the presentation be determined?
