(1) Represents dividends paid and undistributed earnings allocated to nonvested stock-based awards that contain non-forfeitable rights to dividends.
(2) Represents the effect of the assumed exercise of stock options and vesting of restricted shares and restricted stock units utilizing the treasury stock method. Not included are the unvested LTIP awards, which are the Company's performance-based awards.

For the three and nine months ended September 30, 2018 and 2017, there were no anti-dilutive stock based awards that have been excluded from the computation of potential common shares for purposes of calculating diluted EPS as the average market price of the Company's common stock is greater than the exercise prices.

Nonvested stock-based payment awards that contain non-forfeitable rights to dividends are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company’s nonvested stock-based awards qualify as participating securities. 
  
Net income is allocated between the common stock and participating securities pursuant to the two-class method. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating nonvested stock-based awards. Diluted EPS is computed in a similar manner, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method.
