(Dollars in thousands, |  | Quarters Ended June 30, |  |  | Six Months Ended June 30, |
except share and per share data) |  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |
Net income |  | $ | 11,117 |  |  | $ | 33,208 |  |  | $ | 17,911 |  |  | $ | 42,031 |
Basic earnings per share: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Weighted average shares outstanding – basic |  |  | 25,454,579 |  |  |  | 25,128,280 |  |  |  | 25,447,398 |  |  |  | 25,121,171 |

Net income per share |  | $ | 0.43 |  |  | $ | 1.31 |  |  | $ | 0.70 |  |  | $ | 1.66 |
A reconciliation of weighted average shares for basic earnings per share to weighted average shares for diluted earnings per share is as follows:
|  | Quarters Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |

The weighted average shares outstanding used to determine dilutive earnings per share for the quarters ended June 30, 2015 and 2014 do not include 512,500 and 37,500 shares, respectively, which were deemed to be anti-dilutive. The weighted average shares outstanding used to determine dilutive earnings per share for the six months ended June 30, 2015 and 2014 do not include 512,500 and 37,500 shares, respectively, which were deemed to be anti-dilutive.
