The effective income tax rate for the 13 and 39 weeks ended June 25, 2017 was 22.7% and 26.9%, respectively. The majority of the differences between the effective tax rates and the statutory tax rates were due to the transitional adjustments from the 2017 Tax Act as well as the nontaxable income and nondeductible expenses related to the fair value adjustment of the warrants. We file a consolidated federal tax return, as well as combined and separate tax returns in approximately 27 state and local jurisdictions. We have various income tax examinations ongoing which are at different stages of completion, but generally our income tax returns have been audited or closed to audit through 2012. See Note 10 for a discussion of our tax audits. At September 25, 2017, we had approximately $57,856,000 of state net operating loss tax benefits and a federal net operating loss carryforward of approximately $17,850,000.
