| Valuation allowance, methodologies and assumptions | In assessing the need for the valuation allowance, we considered both positive and negative evidence related to the likelihood of realization of the deferred tax assets. As a result of our assessment, we concluded that, beginning in the second quarter of 2013, our estimate of the realization of deferred tax assets would be based solely on the future reversals of existing taxable temporary differences and tax planning strategies that we would make use of to accelerate taxable income to utilize expiring carryforwards. Accordingly, in the second quarter of 2014, the valuation allowance was increased to offset the net deferred tax assets created in the quarter relating primarily to the increase in net operating loss (NOL) carryforwards. | |||
