[1] Net income (loss) was impacted by gains on disposition of assets (primarily the refranchising and sale of related restaurant assets of Applebee's company-operated restaurants) of $16.7 million in the first quarter of 2012, $73.6 million in the third quarter of 2012, $13.0 million in the fourth quarter of 2012, $23.8 million in the first quarter of 2011 and $22.0 million in the fourth quarter of 2011.

[2] The net income and net loss per share were significantly impacted by approximately $21 million of charges related to the termination of the sublease for the Applebee's Restaurant Support Center in Lenexa, Kansas in the 2nd quarter of 2011.

[3] The quarterly amounts may not add to the full year amount as each quarterly calculation is discrete from the full-year calculation.
