--- | ---
Sep. 30, 2013
Income (Loss) Per Common Share | NOTE F — INCOME (LOSS) PER COMMON SHARE Basic income (loss) per common share has been computed by dividing net income (loss) by the weighted-average number of shares of the Company’s common stock outstanding. Diluted income (loss) per common share adjusts net income (loss) and basic income (loss) per common share for the effect of all potentially dilutive shares of the Company’s common stock. The calculations of basic and diluted income (loss) per common share for the three and nine month periods ended September 30, 2013 and 2012 are as follows:
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2013 |  |  | 2012 |  |  | 2013 |  |  | 2012 |
|  | (in thousands, except per share amounts) |
Net income (loss) – basic and diluted |  | $ | 1,093 |  |  | $ | 3,890 |  |  |  | (107 | ) |  | $ | 5,793 |
Weighted-average shares outstanding – basic |  |  | 12,707 |  |  |  | 12,546 |  |  |  | 12,758 |  |  |  | 12,482 |
Effect of dilutive securities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Stock options |  |  | 339 |  |  |  | 254 |  |  |  | — |  |  |  | 298 |
Weighted-average shares outstanding – diluted |  |  | 13,046 |  |  |  | 12,800 |  |  |  | 12,758 |  |  |  | 12,780 |
Basic income (loss) per common share |  | $ | 0.09 |  |  | $ | 0.31 |  |  | $ | (0.01 | ) |  | $ | 0.46 |
Diluted income (loss) per common share |  | $ | 0.08 |  |  | $ | 0.30 |  |  | $ | (0.01 | ) |  | $ | 0.45 |
The computation of diluted income (loss) per common share for the three months ended September 30, 2013 and 2012 excludes options to purchase 336,500 shares and options to purchase 1,158,000 shares, respectively. The computation of diluted income (loss) per common share for the nine months ended September 30, 2013 and 2012 excludes options to purchase 1,777,360 shares and options to purchase 1,328,350 shares, respectively. The above shares were excluded due to their antidilutive effects.
