The determination of impairment of all long-lived assets, goodwill, and intangibles is conducted when indicators of impairment are present and at least annually for goodwill. Impairment testing for goodwill is performed on a reporting segment basis. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">     In the second quarter of 2010, we assessed our Americas region goodwill for impairment. In our assessment, we evaluated the impact on the segment’s fair value due to the recent events in the U.S. Gulf Of Mexico relating to the Macondo Incident, the resulting oil spill and the drilling moratorium. The U.S. Gulf of Mexico market is generally divided into two distinct areas: shallow-water and deepwater. The deepwater market has historically been less volatile and more profitable. Our long-term strategy has been to become more focused on the deepwater business. The ban on new drilling permits issued on April 30 and the deepwater drilling moratorium issued on May 30, 2010 negatively impacted our outlook for deepwater drilling. Based on these factors, which were incorporated into our evaluations and testing as prescribed under U.S. GAAP, we determined that an impairment of our Americas region goodwill existed. As a result, we recorded a $97.7 million impairment charge as of June 30, 2010, reflecting all of our Americas region goodwill. The non-cash charge does not impact our liquidity or debt covenant compliance. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt"><i>Assets Under Construction</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">     In March 2009, we notified a shipyard building three of the vessels in our new build program that they were in default under the construction contract. The default arose as a result of non-performance under the terms of the contract caused by financial difficulties of the shipyard. Construction on these vessels has stopped and we are evaluating our remedies under the contract and under applicable law. We determined that we had a material impairment and recognized a charge of $46.2 million in the first quarter of 2009 pertaining to the construction in progress related to this contract. That charge represented the full amount of our investment in these vessels. The shipyard building the three vessels is in Chapter 11 bankruptcy proceedings. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringFor long-lived assets to be held and used by an entity, disclosures may include a description of the impaired long-lived asset and facts and circumstances leading to the impairment, amount of the impairment loss and where the loss is located in the income statement, method(s) for determining fair value, and the segment in which the impaired long-lived asset is reported.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 144 -Paragraph 26 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Staff Accounting Bulletin (SAB) -Number Topic 5 -Section CC -Subsection 3 falsefalseIMPAIRMENT CHARGES12Impairment ChargesUnKnownUnKnownUnKnownUnKnownfalsetrue
