Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
New Accounting Standards	New Accounting Standards Leases. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet and is effective for interim and annual reporting periods beginning after December 15, 2018, although early adoption is permitted. Adoption of this standard may have a significant impact on our Consolidated Balance Sheets. Although we have not completed our assessment, we do not expect the adoption to change the recognition, measurement, or presentation of lease expenses within the Consolidated Statements of Operations and Cash Flows. For information about our current undiscounted future lease payments and the timing of those payments, see Note 13, “Lease Commitments,” in our Annual Report on Form 10-K for the year ended January 2, 2016.
Earnings per Share	Earnings per Share We calculate basic earnings per share by dividing net income by the weighted average number of common shares outstanding, excluding unvested restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based awards, including restricted stock awards, restricted stock units, performance shares, performance units, and stock options. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material.
