Income Taxes	Income Taxes For the three months ended July 2, 2017, the Company had a loss before income taxes of $297 and a provision for income taxes of $1,548; as such, our effective tax rate for the three months ended July 2, 2017 is not meaningful. The Company’s effective tax rate for the three months ended July 3, 2016 was 29.0%. 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 $2,166 and benefit of $5,239 in the second quarter of 2017 and 2016, respectively, 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 second quarter of 2017 and 2016, which resulted in a benefit of $2,248 and $4,235, respectively), (2) 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, (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. The Company’s effective tax rate for the six months ended July 2, 2017 and July 3, 2016 was 35.6% and 29.2%, respectively. The Company’s effective tax rate varies from the U.S. federal statutory rate of 35% due to the effect of (1) the 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 $3,306 during the six months ended July 2, 2017, (2) 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 six months of 2017 and 2016, which resulted in a benefit of $2,248 and $7,113, respectively), (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. In the second quarter of 2017, the Company increased its unrecognized tax benefits by $8,151 for certain amended state returns. During the next twelve months, we believe that it is reasonably possible the Company will reduce its unrecognized tax benefits by up to $7,002, primarily due to expected settlements with taxing authorities. The current portion of refundable income taxes was $18,526 and $18,111 as of July 2, 2017 and January 1, 2017, respectively, and is included in “Accounts and notes receivable, net” in the condensed consolidated balance sheets. Long-term refundable income taxes are included in “Other assets” and amounted to $956 and $239 as of July 2, 2017 and January 1, 2017, respectively.
