2. | Stock Based Compensation
The Company estimates the fair value of restricted stock and stock option grants at the date of grant and amortizes those amounts into expense on a straight line basis or amount vested, if greater, over the appropriate vesting period. As of June 30, 2013, there was $5,258,000 of unrecognized compensation costs related to the outstanding shares of restricted stock, which is expected to be recognized over a weighted average period of 3.43 years. The Company used a 0% discount factor and forfeiture rate for determining the fair value of restricted stock. The forfeiture rate was based on historical results and trends. The holder of a restricted stock award is generally entitled at all times on and after the date of issuance of the restricted stock to exercise the rights of a stockholder of the Company, including the right to vote the shares and the right to receive dividends on the shares. Restricted stock activity is summarized as follows:
|  | Shares Outstanding |  | Weighted Average Grant Date Fair Value |
Unvested restricted stock at January 1, 2013 |  |  | 250,180 |  | $ | 22.66 |
Restricted stock granted |  |  | 83,300 |  |  | 27.57 |
Restricted stock vested |  |  | (71,630) |  |  | 22.52 |
Restricted stock forfeited |  |  | (6,940) |  |  | 23.88 |
Unvested restricted stock at June 30, 2013 |  |  | 254,910 |  | $ | 24.27 |
