Deferred tax assets are recognized if sufficient future taxable income, including income from the reversal of existing taxable temporary differences and available tax planning strategies, is available for realization. The utilization of deferred tax assets arising from temporary differences depends on the generation of sufficient taxable profits in the period in which the underlying asset or liability is recovered or settled. The utilization of deferred tax assets arising from unused tax losses or tax credits depends on the generation of sufficient taxable profits before the unused tax losses or tax credits expire. As of each balance sheet date, management evaluates the recoverability of deferred tax assets and if it is considered probable, that all or a portion of the deferred tax asset will not be utilized, then a valuation allowance is recognized.
