[1] Our state tax benefit, net of federal effect is zero due to a mix of jurisdictions with and without valuation allowances and other impacts. However, the jurisdictions that make up the majority (greater than 50%) of our composite state tax (apportioned tax-effected pre-tax loss) used in computing the state tax provision are Illinois, Georgia, Minnesota, Wisconsin, Michigan, South Carolina, California, Indiana and Pennsylvania.
