6.	Earnings Per Share

Basic earnings per share is calculated by dividing our net income by the weighted average number of common shares outstanding during the period, excluding nonvested restricted stock which is considered to be contingently issuable. To calculate diluted earnings per share, common share equivalents are added to the weighted average number of common shares outstanding. Common share equivalents are calculated using the treasury stock method and are computed based on outstanding stock-based awards. Stock-based awards of 15,413 shares and 15,680 shares were excluded from the calculation of diluted earnings per share as of September 30, 2017 and September 24, 2016, respectively, as their effect would have been anti-dilutive.

The following table sets forth the computation of basic earnings per share and diluted earnings per share:
