Options totaling

17,000

equivalent shares for each of the

three

-month and

six

-month periods ended

June 30, 2018,

and

373,667

and

380,000

equivalent shares for the

three

-month and

six

-month periods ended

June 30, 2017,

respectively, were outstanding but were

not

included in the calculation of diluted earnings per share because including the options in the denominator would be antidilutive, or decrease the number of weighted-average shares, due to their exercise prices exceeding the average market price of the common shares, or because inclusion of average unrecognized compensation expense in the calculation would cause the options to be antidilutive.

Unvested performance unit awards totaling

109,255

equivalent shares for each of the

three

-month and

six

-month periods ended

June 30, 2018,

and

132,305

equivalent shares for each of the

three

-month and

six

-month periods ended

June 30, 2017,

were considered outstanding but were

not

included in the calculation of diluted earnings per share because inclusion of average unrecognized compensation expense in the calculation would cause the performance units to be antidilutive.
