In general, a valuation allowance is recorded if based on the weight of available evidence it is more likely than not that some portion or all of the deferred tax asset will not be realized. Realization of the Company's deferred tax assets is dependent upon the Company generating sufficient taxable income in future years in the appropriate tax jurisdictions to obtain a benefit from the reversal of deductible temporary differences and from loss carryforwards. Based on the timing of reversal of future taxable amounts and the Company's recent history of losses and future expectations of reporting taxable losses, management does not believe it met the requirements to realize the benefits of certain of its deferred tax assets and has adjusted the valuation allowance by $0.7 million.
