In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of its U.S. deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. Management considers the scheduled reversal of deferred tax liabilities, change of control limitations, projected future taxable income and tax planning strategies in making this assessment. Guidance under ASC 740, Income Taxes, (“ASC 740”) states that forming a conclusion that a valuation allowance is not needed is difficult when there is negative evidence, such as cumulative losses in recent years in the jurisdictions to which the deferred tax assets relate. In years 2010 through to 2012, it was determined by management that it was more likely than not that certain deferred tax assets associated with the U.S. jurisdiction would be realized and as such, no valuation allowance was recorded against these deferred tax assets. In 2013, it was determined by management that a partial valuation allowance was required to be recorded against certain deferred tax assets associated with the U.S. jurisdiction as it was not more likely than not to be realized. In 2014, it was determined by management that a full valuation allowance was required to be recorded against the remaining deferred tax assets associated with the U.S. jurisdiction as it was not likely to be realized. The Canadian jurisdiction continues to have a full valuation allowance recorded against the deferred tax assets. In the first quarter of 2015, it was concluded by management that a full valuation allowance associated with the U.S. jurisdiction was still appropriate.
