Other Information Pertaining to Income Taxes	In December 2014, the IRS issued a Statutory Notice of Deficiency for 2009, 2010 and 2011.  During the quarter ended March 28, 2015, we filed our petition to the U.S. Tax Court disputing the adjustments proposed by the IRS. During the quarter ended June 27, 2015, we were notified by the IRS that our protest was transferred to the Appellate Divisions (Appeals Section) of the IRS. During the quarter ended March 26, 2016, we filed our protest with the Appellate Division. The opening appeals conference was held on June 8, 2016 and a proposed settlement was reached.  On July 13, 2016, a joint status report was filed with the Tax Court indicating a basis for settlement has been reached on all of the issues in this case.  On October 19, 2016 an executed decision document was signed by the Internal Revenue Service’s Special Trial Attorney and submitted to the Tax Court finalizing the settlement. During the third quarter of 2016, the Company elected to early adopt Accounting Standards Update (“ASU”) No. 2015-17 (Topic 740), Balance Sheet Classification of Deferred Taxes, prospectively. As a result, all deferred tax assets and liabilities will be presented as noncurrent on the consolidated balance sheet. There was no impact on our results of operations as a result of the adoption of ASU 2015-17 and prior periods have not been adjusted.
