These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions we made when accounting for items and matters such as, but not limited to, investments, long-term contracts, customer retention patterns, allowance for doubtful accounts, depreciation, amortization, asset valuations, internal labor capitalization rates, recoverability of assets (including deferred tax assets), impairment assessments, pension, post-retirement and other post-employment benefits, taxes, certain liabilities and other provisions and contingencies are reasonable, based on information available at the time they were made. These estimates, judgments and assumptions can affect the reported amounts of assets, liabilities and components of stockholders' equity as of the dates of the consolidated balance sheets, as well as the reported amounts of revenue, expenses and components of cash flows during the periods presented in our consolidated statements of operations, our consolidated statements of comprehensive (loss) income and our consolidated statements of cash flows. We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 12—Income Taxes and Note 15—Commitments and Contingencies for additional information.</font></p> <p style="FONT-FAMILY: times"><font size="2">        For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.</font></p> <p style="FONT-FAMILY: times"><font size="2">        For matters related to income taxes, if the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. No portion of an uncertain tax position will be recognized if the position has less than a 50% likelihood of being sustained. Interest is recognized on the amount of unrecognized benefit from uncertain tax positions.</font></p> <p style="FONT-FAMILY: times"><font size="2">        For all of these and other matters, actual results could differ from our estimates.</font></p></div>

We evaluated the error considering both quantitative and qualitative factors and concluded that the error was immaterial to our previously issued and current period consolidated financial statements. Therefore, we recognized a $30 million reduction in depreciation expense during the year ended December 31, 2012. The correction of the error resulted in an increase in net income of $19 million, or approximately $0.03 per basic and diluted common share, for the year ended December 31, 2012.</font></p></div>
