(In thousands, except per share amounts) |  | 20 14 |  |  | 2013 |  |  | 2012 |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net income |  | $ | 29,834 |  |  | $ | 30,147 |  |  | $ | 27,267 |
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Basic earnings per common share - weighted-average shares |  |  | 33,381 |  |  |  | 33,221 |  |  |  | 33,095 |
Effect of dilutive stock options |  |  | 297 |  |  |  | 208 |  |  |  | 130 |
Diluted earnings per common share - weighted-average shares and assumed conversions |  |  | 33,678 |  |  |  | 33,429 |  |  |  | 33,225 |

Diluted earnings per common share |  | $ | 0.89 |  |  | $ | 0.90 |  |  | $ | 0.82 |
Options totaling 176,500, 304,600 and 697,725 equivalent shares were outstanding but were not included in the calculation of diluted earnings per share for 2014, 2013 and 2012, respectively, because including the options in the denominator would be antidilutive, or decrease the number of weighted-average shares, due to their exercise prices exceeding the average market price of the common shares, or because inclusion of average unrecognized compensation expense in the calculation would cause the options to be antidilutive. Unvested performance unit awards (see Note 11) totaling 39,885, 47,636 and 65,400 equivalent shares for 2014, 2013 and 2012, respectively, were considered outstanding but were not included in the calculation of diluted earnings per share because inclusion of average unrecognized compensation expense in the calculation would cause the performance units to be antidilutive.
