PDS Precision Drilling Corporation New

Precision Drilling Corporation ("Precision") announced today that it has reached an agreement with the Canada Revenue Agency ("CRA") to resolve a tax reassessment made by the CRA and disputed by Precision.

As previously disclosed in public filings, on February 9, 2011, Precision received a notice of reassessment from the CRA for federal tax and interest totaling $216 million relating to a transaction that occurred in the 2005 tax year. Precision objected to the reassessment and was required to pay $108 million toward the reassessed balance as part of the appeal process.

Based on the settlement agreement, Precision anticipates receiving an income tax reassessment from the CRA of $26 million federal tax plus interest of $11 million. The anticipated reassessed total of $37 million is $179 million less than the February reassessment and will result in a refund of $71 million to Precision. As part of the settlement agreement, Precision will waive all rights to appeal the reassessment. Additionally, Precision anticipates that the CRA settlement should result in an Alberta income tax reassessment and interest charges totaling $13 million.

A $50 million onetime charge related to the CRA settlement and expected provincial tax reassessment will be reflected in Precision's third quarter net earnings. Also, as a result of the settlement, Precision's contingent tax liability previously disclosed in Note 16 of its second quarter financial statements will be reduced from $350 million to $58 million, a reduction of $292 million.

"We believe the settlement, which eliminates a potentially significant tax liability, is in the best long-term interests of Precision and its shareholders. We are pleased to have resolution to this matter and close the final chapter of a 2005 transaction." said Rob McNally, Precision's Executive Vice President and Chief Financial Officer.
