Our 2014 Omnibus Equity Incentive Plan (the “2014 Plan”) authorizes the issuance of distribution equivalent rights, incentive stock options, non-qualified stock options, performance stock, performance units, restricted ordinary shares, restricted stock units, stock appreciation rights, tandem stock appreciation rights and unrestricted ordinary shares to our directors, officer, employees, consultants and advisors. The Company has reserved up to 300,000 shares of common stock for issuance under the 2014 Plan.

These awards are valued at the grant date by determining the fair value of the instruments, net of estimated forfeitures. The value of each award is amortized on a straight-line basis over the requisite service period.
