based on our historical experience , calculating the contractual allowance reserve percentage at the payor level is sufficient to allow us to provide the necessary detail and accuracy with our collectibility estimates . however , the services authorized and provided and related reimbursement are subject to interpretation that could result in payments that differ from our estimates . payor terms are periodically revised necessitating continual review and assessment of the estimates made by management . our billing system may not capture the exact change in our contractual allowance reserve estimate from period to period . therefore , in order to assess the accuracy of our revenues and hence our contractual allowance reserves , our management regularly compares its cash collections to corresponding net revenues measured both in the aggregate and on a clinic-by-clinic basis . in the aggregate , the historical difference between net revenues and corresponding cash collections has generally reflected a difference within approximately 1 % of net revenues . additionally , analysis of subsequent period 's contractual write-offs on a payor basis reflects a difference within approximately 1 % between the actual aggregate contractual reserve percentage as compared to the estimated contractual allowance reserve percentage associated with the same period end balance . as a result , we believe that a reasonable likely change in the contractual allowance reserve estimate would not be more than 1 % at december 31 , 2014. for purposes of demonstrating the sensitivity of this estimate on the company 's financial condition , a one percent increase or decrease in our aggregate contractual allowance reserve percentage would decrease or increase , respectively , net patient revenue by approximately $ 798,000 for the year ended december 31 , 2014. management believes the changes in the estimate of the contractual allowance reserve for the

accounts receivable aging and rely on prior experience with particular payors to determine an appropriate reserve for doubtful accounts . historically , clinics that have a large number of aged accounts generally have less favorable collection experience , and thus , require a higher allowance . accounts that are ultimately determined to be uncollectible are written off against our bad debt allowance . the amount of our aggregate allowance for doubtful accounts is regularly reviewed for adequacy in light of current and historical experience . accounting for income taxes . we account for

carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards . deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled . the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date . the company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit . for tax positions meeting the more-likely-than-not threshold , the amount to be recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority . we do not believe that we have any significant uncertain tax positions at december 31 , 2014 , nor is this expected to change within the next twelve months due to the settlement and expiration of statutes of limitation . we did not have any accrued interest or penalties associated with any unrecognized tax benefits nor was any interest expense recognized during the twelve months ended december 31 , 2014 and 2013. carrying value of long-lived assets . our

annually and upon the occurrence of certain events , and are written down to fair value if considered impaired . we evaluate goodwill for impairment on at least an annual basis ( in the third quarter

million in 2012. as a percentage of operating income before corporate office costs , net income attributable to non-controlling interests was 13.2 % in 2013 compared to 13.4 % in 2012. the reduction
