Increase to tax valuation allowance for deferred tax assets $ 73  
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 periodic assessment, our estimate of the realization of deferred tax assets is solely based 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 NOL and tax credit carryforwards.
