Income Tax Disclosure [Abstract]
Income Taxes	20. Income Taxes The Company has provided for income taxes in fiscal year 2020 interim periods based on the estimated effective income tax rate for the complete fiscal year, as adjusted for discrete tax events, including excess tax benefits or deficiencies related to stock-based compensation, in the period such events occur. The estimated annual effective tax rate is computed based on the expected annual pretax income of the consolidated entities located within each taxing jurisdiction based on legislation enacted as of the balance sheet date. For the three months ended June 27, 2020 and June 29, 2019, the Company recorded discrete tax benefits of approximately $7.5 million and $2.6 million, respectively, related to excess tax benefits realized from stock-based compensation. For the six months ended June 27, 2020 and June 29, 2019, the Company recorded discrete tax benefits of approximately $17.1 million and $6.0 million, respectively, related to excess tax benefits realized from stock-based compensation. Deferred tax assets and liabilities are determined based on the future tax consequences associated with temporary differences between income and expenses reported for accounting and tax purposes. A valuation allowance for deferred tax assets is recorded to the extent that the Company cannot determine that the ultimate realization of the net deferred tax assets is more likely than not. Realization of deferred tax assets is principally dependent upon the achievement of future taxable income, the estimation of which requires significant judgment by the Company’s management. The judgment of the Company’s management regarding future profitability may change due to many factors, including future market conditions and the Company’s ability to successfully execute its business plans or tax planning strategies. These changes, if any, may require material adjustments to these deferred tax asset balances. As of June 27, 2020, the liability for income taxes associated with uncertain tax positions was approximately $18.5 million. If fully recognized, approximately $17.1 million (net of federal benefit on state taxes) would impact the Company’s effective tax rate. It is reasonably possible that the amount of unrecognized tax benefits in various jurisdictions may change in the next twelve months due to the expiration of statutes of limitation and audit settlements. However, due to the uncertainty surrounding the timing of these events, an estimate of the change within the next twelve months cannot currently be made. The Company conducts business in multiple jurisdictions and, as a result, one or more of the Company’s subsidiaries files income tax returns in U.S. federal, various state, local and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters through fiscal year 2015. All material state, local and foreign income tax matters have been concluded through fiscal year 2012. The Company does not believe that the results of any tax authority examination would have a significant impact on its consolidated financial statements. In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was enacted and signed into law in response to the market volatility and instability resulting from the COVID-19 pandemic. It includes a significant number of tax provisions and lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017. The changes are primarily related to: (1) the business interest expense disallowance rules for 2019 and 2020; (2) net operating loss rules; (3) charitable contribution limitations; (4) employee retention credit; and (5) the realization of corporate alternative minimum tax credits. The Company continues to assess the impact and future implications of these provisions; however, it does not anticipate any amounts that could give rise to a material impact to the Company’s condensed consolidated financial statements.
