Terms of award |  | The Company’s common stock on the date of grant. Shares of non-vested restricted stock are generally subject to vesting in three equal annual installments either on the first, second and third anniversary of the date of the grant or the third, fourth and fifth anniversary of the date of the grant, or 100% on the first anniversary of the date of the grant. For restricted stock awards granted under the 2013 DSCP plan, each recipient may elect to defer receipt of shares and instead receive restricted stock units (“Deferred Stock Units”), which represent contingent rights to receive shares of the Company’s common stock on the date of recipient separation from service from the Board of Directors, or, if earlier, upon a change in control event of the Company. Deferred Stock Units become vested 100% on the first anniversary of the date of the grant. |  |  |
