These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions we make when accounting for specific items and matters, including, but not limited to, revenue recognition, revenue reserves, network access costs, network access cost dispute reserves, investments, long-term contracts, customer retention patterns, allowance for doubtful accounts, depreciation, amortization, asset valuations, rates used for affiliate cost allocations, internal labor capitalization rates, recoverability of assets (including deferred tax assets), impairment assessments, taxes, certain liabilities and other provisions and contingencies, are reasonable, based on information available at the time they are made. These estimates, judgments and assumptions can materially affect the reported amounts of assets, liabilities and components of stockholder's 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 other consolidated financial statements. We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See </span><span style="font-family:Arial;font-size:10pt;">Note 12—Income Taxes</span><span style="font-family:Arial;font-size:10pt;"> and </span><span style="font-family:Arial;font-size:10pt;">Note 16—Commitments, Contingencies and Other Items</span><span style="font-family:Arial;font-size:10pt;"> for additional information.</span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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.</span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-indent:36px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">For matters related to income taxes, if we determine that 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 </span><span style="font-family:Arial;font-size:10pt;">50%</span><span style="font-family:Arial;font-size:10pt;"> likelihood of being sustained.
