(1)

The third quarter 2012 net income and earnings per share were impacted by a $26.4 million loss on early extinguishment of debt in connection with a redemption and repurchase of the Company's $520.0 million previously outstanding senior secured notes. The fourth quarter 2012 net income and earnings per share were impacted by a decrease in unrecognized tax benefits of $52.4 million resulting from expiring statute of limitation periods related to an historical Canadian debt restructuring transaction.


(2)	Items shown separately on the statements of income consist of (i) accretion of environmental liabilities and (ii) depreciation and amortization.

Earnings per share are computed independently for each of the quarters presented. Accordingly, the quarterly basic and diluted earnings per share may not equal the total computed for the year.
