Earnings Per Share [Abstract]
Earnings/(Loss) Per Share	Earnings/(Loss) Per Share We compute earnings/(loss) per share using a two-class method, an earnings allocation method used when a company’s capital structure includes either two or more classes of common stock or common stock and participating securities. This method determines earnings/(loss) per share based on dividends declared on common stock and participating securities (i.e., distributed earnings), as well as participation rights of participating securities in any undistributed earnings. Earnings/(loss) per share is computed using both basic shares and diluted shares. The difference between basic and diluted shares is that diluted shares include the dilutive effect of the assumed exercise of outstanding securities. Our stock options, stock-settled long-term performance awards and restricted stock units could have the most significant impact on diluted shares. The decrease in our basic shares is primarily due to repurchases of the Company’s Class A Common Stock. The difference between basic and diluted shares of approximately 2.1 million, 2.3 million and 1.7 million as of December 30, 2018, December 31, 2017 and December 25, 2016, respectively, resulted primarily from the dilutive effect of certain stock options and performance awards. Securities that could potentially be dilutive are excluded from the computation of diluted earnings per share when a loss from continuing operations exists or when the exercise price exceeds the market value of our Class A Common Stock, because their inclusion would result in an anti-dilutive effect on per share amounts. There were no anti-dilutive stock options excluded from the computation of diluted earnings per share in 2018. The number of stock options excluded from the computation of diluted earnings per share because they were anti-dilutive was approximately 2 million in 2017 and 4 million in 2016. There were no anti-dilutive stock-settled long-term performance awards and restricted stock units excluded from the computation of diluted earnings per share for the year ended 2018, 2017 and 2016.

Earnings/(Loss) Per Share

We compute earnings/(loss) per share using a two-class method, an earnings allocation method used when a company’s capital structure includes either two or more classes of common stock or common stock and participating securities. This method determines earnings/(loss) per share based on dividends declared on common stock and participating securities (i.e., distributed earnings), as well as participation rights of participating securities in any undistributed earnings.

Earnings/(loss) per share is computed using both basic shares and diluted shares. The difference between basic and diluted shares is that diluted shares include the dilutive effect of the assumed exercise of outstanding securities. Our stock options, stock-settled long-term performance awards and restricted stock units could have the most significant impact on diluted shares. The decrease in our basic shares is primarily due to repurchases of the Company’s Class A Common Stock. The difference between basic and diluted shares of approximately 2.1 million, 2.3 million and 1.7 million as of December 30, 2018, December 31, 2017 and December 25, 2016, respectively, resulted primarily from the dilutive effect of certain stock options and performance awards.

Securities that could potentially be dilutive are excluded from the computation of diluted earnings per share when a loss from continuing operations exists or when the exercise price exceeds the market value of our Class A Common Stock, because their inclusion would result in an anti-dilutive effect on per share amounts.

There were no anti-dilutive stock options excluded from the computation of diluted earnings per share in 2018. The number of stock options excluded from the computation of diluted earnings per share because they were anti-dilutive was approximately 2 million in 2017 and 4 million in 2016.

There were no anti-dilutive stock-settled long-term performance awards and restricted stock units excluded from the computation of diluted earnings per share for the year ended 2018, 2017 and 2016.
