diluted earnings per share because to do so would have been antidilutive.

We completed a voluntary stock option exchange
program on March 21, 2011 and exchanged 2.5 million stock options granted under the 2008 Executive Incentive Plan for 1.3 million replacement stock options with a lower exercise price and different service and performance vesting
conditions. We accounted for the exchange program as a modification of the existing awards under ASC 718 and will recognize incremental compensation expense of approximately $1.0 million over the service period of the new awards.
