At March 31, 2016, there was $1,835,000 of total unrecognized compensation expense from stock-based compensation granted under the plans, which is related to non-vested shares.

Restricted Stock or Restricted Stock Units (collectively “RS”) During the years ended March 31, 2016 and 2015, the Company granted 49,702 and 95,645 shares of RS, respectively, with an estimated grant date fair value of $1,566,000 and $2,316,000, respectively, which was based on the closing market price on the date of grant. The fair value related to these awards is recognized as compensation expense over the vesting period. These awards generally vest in three equal installments beginning each anniversary from the grant date, subject to continued employment. Upon vesting, these awards may be net share settled to cover the required withholding tax with the remaining amount converted into an equivalent number of shares of common stock.
