The diluted earnings per share calculationsexclude the dilutive effect of 0 and 354,000 common stock equivalents for the three months ended June 30, 2013and 2012, respectively,and 0 and 366,000 common stock equivalents for the six months endedJune 30, 2013 and 2012, respectively, because the exercise prices were higher than the average market price.The Series H Cumulative Convertible and Redeemable Preferred Stockand Series I Cumulative Convertible Perpetual Preferred Stock were not included in the calculations as the effect of conversions into common stock was anti-dilutive.
