Grace Energy Corporation Matter In connection with the settlement of the Grace Energy Corporation matter, we recognized a pre-tax gain of $28.7 million within one of our taxable subsidiaries. As a result, we recorded related income tax expense of $10.1 million, resulting from the reduction of the related deferred income tax asset. See Note 6. Commitments and Contingencies for a discussion on the Grace Energy Corporation matter. Canadian Income Tax Audit During the second quarter of 2012, we recorded $1.0 million of additional income tax liability and $2.2 million of interest and penalties associated with an ongoing Canadian income tax audit for the years 2006 through 2011. We also recorded $1.3 million of Canadian withholding tax and $0.7 million of interest and penalties associated with the withholding tax liability related to interest payments made from our Canadian subsidiaries to a United States entity from 2003 to 2009. We believe that adequate provisions for uncertainties related to the Canadian audits have been reflected in the financial statements.
