Income Taxes

There have been no material changes to the balance of unrecognized tax benefits during the third quarter 2011 and 2010. Last year the Company recorded an income tax charge of $22 million or $0.02 per share primarily related to the merger of the Company's former Intermodal subsidiary with CSXT.  As a result of this merger, CSXT's effective state tax rate increased and resulted in a revaluation of the deferred tax liabilities.
