Income Taxes	Income Taxes The Company’s effective tax rate for the three months ended October 1, 2017 and October 2, 2016 was 54.8% and 37.2%, respectively. The Company’s effective tax rate varies from the U.S. federal statutory rate of 35% due to the effect of (1) the system optimization initiative provision of $5,019 and $2,332 in the third quarter of 2017 and 2016, respectively, reflecting goodwill adjustments, changes to valuation allowances on state net operating loss carryforwards and state deferred taxes, (2) state income taxes net of federal benefits, including non-recurring changes to state deferred taxes, (3) the adoption of an amendment issued by the Financial Accounting Standards Board (“FASB”), which requires that excess tax benefits and tax deficiencies related to share-based payments be recognized in net income and (4) the rate differential between foreign and domestic taxes. The Company’s effective tax rate for the nine months ended October 1, 2017 and October 2, 2016 was 45.2% and 33.3%, respectively. The Company’s effective tax rate varies from the U.S. federal statutory rate of 35% due to the effect of (1) the system optimization initiative, reflecting goodwill adjustments, changes to valuation allowances on state net operating loss carryforwards and state deferred taxes (including corrections to prior years identified and recorded in the first nine months of 2017 and 2016, which resulted in a benefit of $2,248 and $7,113, respectively), (2) the adoption of an amendment issued by the FASB, which requires that excess tax benefits and tax deficiencies related to share-based payments be recognized in net income, which resulted in a benefit of $5,205 during the nine months ended October 1, 2017, (3) state income taxes net of federal benefits, including non-recurring changes to state deferred taxes, and (4) the rate differential between foreign and domestic taxes.
