Share-based Payments [Abstract] |
Share-based Payments | 16. Share-based Payments Stock Options The Company granted options to purchase 241,800 and 163,100 shares of common stock during the three months ended June 30, 2018 and 2017, respectively. The cost associated with stock options is estimated using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions including the expected volatility of the underlying stock and the expected holding period of the option. These subjective assumptions are based on both historical and other information. Changes in the values assumed and used in the model can materially affect the estimate of fair value. The following assumptions were used to derive the weighted average fair value of the stock options granted:
|  | Three Months Ended June 30, |
|  | 2018 |  |  | 2017 |
Weighted average risk free interest rate |  |  | 2.82 | % |  |  | 1.90 | %
Weighted average expected holding period (years) |  |  | 5.95 |  |  |  | 5.82 |
Weighted average expected volatility |  |  | 43.98 | % |  |  | 47.36 | %
Weighted average expected dividend yield |  |  | - |  |  |  | - |
Weighted average fair value of options granted |  | $ | 8.70 |  |  | $ | 12.69 |
The following is a summary of stock option transactions:
|  | Number of Shares |  |  | Weighted Average Exercise Price |
Outstanding at March 31, 2018 |  |  | 1,143,298 |  |  | $ | 16.97 |
Granted |  |  | 241,800 |  |  | $ | 19.00 |

Forfeited |  |  | (4,500 | ) |  | $ | 28.58 |
Outstanding at June 30, 2018 |  |  | 1,380,598 |  |  | $ | 17.29 |
At June 30, 2018, options to purchase 450,765 shares of common stock were unvested at the weighted average exercise price of $23.31. At June 30, 2018, there was $4,343,000 of total unrecognized compensation expense related to unvested stock option awards. The compensation expense is expected to be recognized over a weighted average vesting period of approximately 2.3 years. Restricted Stock Units (“RSUs”) During the three months ended June 30, 2018 and 2017, the Company granted 78,400 and 60,000 shares of RSUs, respectively, with an estimated grant date fair value of $1,490,000 and $1,644,000, respectively, which was based on the closing market price on the grant date. The following is a summary of non-vested RSUs:
|  | Number of Shares |  |  | Weighted Average Grant Date Fair Value |
Outstanding at March 31, 2018 |  |  | 133,828 |  |  | $ | 28.37 |
Granted |  |  | 78,400 |  |  | $ | 19.00 |
Vested |  |  | (33,366 | ) |  | $ | 27.88 |

At June 30, 2018, there was $3,652,000 of unrecognized compensation expense related to these awards, which will be recognized over the remaining vesting period of approximately 2.2 years.
