Note 9—Impairments
During the three- and six-month periods of 2013 and 2012, we recognized before-tax impairment charges within the following segments:
|  | Millions of Dollars
|  | Three Months Ended |  | Six Months Ended
June 30 | June 30
|  |  | 2013 |  | 2012 |  | 2013 |  | 2012
Canada |  | $ | - |  | - |  | - |  | 213
Europe |  |  | 28 |  | 78 |  | 28 |  | 79
Asia Pacific and Middle East |  |  | - |  | 4 |  | 2 |  | 4
|  | $ | 28 |  | 82 |  | 30 |  | 296
In t he second quarters of 2 013 and 2012, we recorded impairments in our Europe segment of $2 8 million and $78 million, respectively, primarily due to increase s in the asset retirement obligation for the Don Field in the United Kingdom, which has ceased production. Additionally, t he six-month period of 2012 included a $213 million property impairment in our Canada segment for the carrying value of capitalized project development costs associated with our Mackenzie Gas Project. Advancement of the project was suspended indefinitely in the first quarter of 2012 due to a continued decline in market conditions and the lack of acceptable commercial terms. We also recorded a $481 million impairment for the undeveloped leasehold costs associated with the project, which was included in the “Exploration expenses” line on our consolidated income statement.
