Earnings Per Share [Abstract] |
EARNINGS PER SHARE | EARNINGS PER SHARE Basic income per share is calculated using the weighted average number of shares of common stock outstanding during the period. Stock options and restricted stock are included in the calculation of diluted earnings per share, except when their effect would be anti-dilutive. For the six months ended March 31, 2018, 1.0 million shares of stock options and restricted stock were excluded due to the Company's net loss. The following tables reflect a reconciliation of the shares used in the basic and diluted net income per share computation for the three months ended March 31, 2018 and April 1, 2017:
