EPS [Abstract]

EPS

12. Earnings per Share

Basic EPS is based on the weighted-average number of DPL common shares outstanding during the year. Diluted EPS is based on the weighted-average number of DPL common and common-equivalent shares outstanding during the year, except in periods where the inclusion of such common-equivalent shares is anti-dilutive. Excluded from outstanding shares for these weighted-average computations were shares held by DP&L's Master Trust Plan for deferred compensation and unreleased shares held by DPL's ESOP.

The common-equivalent shares excluded from the calculation of diluted EPS, because they were anti-dilutive, were not material for the three months ended March 31, 2011.  Effective with the Merger with AES, DPL is wholly owned by AES and earnings per share information is no longer required.

The following illustrates the reconciliation of the numerators and denominators of the basic and diluted EPS computations:
