Instruments that could potentially have a dilutive effect on the Company’s weighted average shares outstanding include all of the outstanding convertible notes, restricted share units, stock options, stock appreciation rights, and warrants. These instruments are currently excluded from the calculation of diluted earnings per share as they are antidilutive for the periods presented.
