    Earnings (Loss) Per Common Share

We are authorized to issue

750,000,000

shares of common stock,

$0.25

par value per share. At

2018,

there were

406,549,168

shares of our common stock issued and

5,226,791

shares issued and held in treasury, for a net of

401,322,377

shares outstanding.

Diluted income (loss) per share for the

three

and

six

months ended

June 

30,

2018

and

2017

excludes the potential effects of outstanding shares of our convertible preferred stock, as their conversion would have

no

effect on the calculation of dilutive shares.

For the

three

-month and

six

-month periods ended

June 

30,

2018,

the calculation of diluted income per share included dilutive (i) restricted stock units that were unvested or which vested in the current period of

1,268,601

and

1,179,086,

respectively, and (ii) deferred shares of

1,721,932

for each period. For the

three

-month period ended

June 

30,

2017,

all restricted share units and deferred shares were excluded from the computation of diluted loss per share, as our reported loss for that period would cause them to have

no

effect on the calculation of loss per share. For the

six

-month period ended

June 

30,

2017,

dilutive restricted stock units that were unvested or which vested in the current period of
