Basic net income per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of shares and, if dilutive, common equivalent shares, determined using the treasury stock method for stock options, restricted stock awards and restricted stock units outstanding during the period. A reconciliation of the shares used in calculating basic and diluted net income per share is as follows:

	Three Months Ended				Nine Months Ended
	October 27, 2018		October 28, 2017		October 27, 2018		October 28, 2017
Weighted Average Common Shares Outstanding - Basic		6,924,554		6,725,414		6,858,365		6,968,285
Effect of Dilutive Options, Restricted Stock Awards and Restricted Stock Units		242,074		95,507		197,760		114,076
Weighted Average Common Shares Outstanding - Diluted		7,166,628		6,820,921		7,056,125		7,082,361

For the three and nine months ended October 27, 2018, the diluted per share amounts do not reflect common equivalent shares outstanding of 228,600 and 333,175, respectively. For the three and nine months ended October 28, 2017, the diluted per share amounts do not reflect common equivalent shares outstanding of 609,934 and 612,248, respectively. These outstanding common equivalent shares were not included due to their anti-dilutive effect. Anti-dilutive shares consist of those common stock equivalents that have an exercise price above the average stock price for the period or for which the common stock equivalent’s related average unrecognized stock compensation expense is sufficient to “buy back” the entire amount of shares. Restricted stock units which vest based upon achievement of performance targets are excluded from the diluted shares outstanding unless the performance targets have been met as of the end of the reporting period, regardless of whether such performance targets are probable of achievement as of the end of the measurement period.
