Net Income (Loss) Per Share | 14. NET INCOME (LOSS) PER SHARE: The following is a reconciliation of the shares used in the denominator for calculating basic and diluted net income (loss) per share for the fiscal years ended September 30,
|  | 2011 |  |  | 2012 |  |  | 2013 |
Weighted average common shares outstanding used in calculating basic income (loss) per share |  |  | 22,375,271 |  |  |  | 22,740,986 |  |  |  | 23,253,992 |
Effect of dilutive options |  |  | — |  |  |  | 594,932 |  |  |  | 749,736 |
Weighted average common and common equivalent shares used in calculating diluted income (loss) per share |  |  | 22,375,271 |  |  |  | 23,335,918 |  |  |  | 24,003,728 |
During the fiscal years ended September 30, 2012 and 2013, there were 1,546,207 and 1,728,042 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income (loss) per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the fiscal year ended September 30, 2011, no options were included in the computation of diluted loss per share because we reported a net loss and the effect of their inclusion would have been anti-dilutive.
