publicly announce the results of any revisions to any such statements to reflect future events or developments . overview our business strategy is to acquire and develop inpatient behavioral healthcare facilities and improve our operating results within our inpatient facilities and our other behavioral healthcare operations . our goal is to improve the operating results of our facilities by providing high quality services , expanding referral networks and marketing initiatives while meeting the increased demand for behavioral healthcare services through expansion of our current locations as well as developing new services within existing locations . on march 1 , 2012 , we completed the acquisition of three inpatient behavioral healthcare facilities with a combined 166 licensed beds from haven for $ 91.0 million of cash consideration . also on march 1 , 2012 , we amended our senior secured credit facility to provide an incremental $ 25.0 million of term loans and increase the revolving credit facility by $ 45.0 million , from $ 30.0 million to $ 75.0 million . we used the net proceeds from the sale of our common stock , the incremental term loans of $ 25.0 million and a $ 5.0 million borrowing under the revolving credit facility to fund the acquisition of the haven facilities . on december 20 , 2011 , we completed the offering of 9,583,332 shares of our common stock ( including shares sold pursuant to the exercise of the over-allotment option that we granted to the underwriters as part of the offering ) at a price of $ 7.50 per share . the net proceeds to us from the sale of the shares , after deducting the underwriting discount of approximately $ 3.8 million and additional offering-related expenses of approximately $ 0.9 million , were approximately $ 67.2 million . 25 on november 1 , 2011 , we completed our acquisition of phc , a leading national provider of inpatient and outpatient mental health and drug and alcohol addiction treatment programs in delaware , michigan , nevada , pennsylvania , utah and virginia . in connection with the acquisition , we issued $ 150.0 million of our senior notes and used the proceeds of such debt issuance primarily to pay a cash distribution of $ 74.4 million to existing acadia stockholders , repay phc debt of $ 26.4 million , fund the $ 5.0 million cash portion of the acquisition consideration issued to the holders of phc 's class b common stock , pay a $ 20.6 million fee to terminate the professional services agreement between acadia and waud capital partners and pay transaction-related expenses . the senior notes were issued at a discount of $ 2.5 million . additionally , pursuant to the phc merger agreement , we issued 4,891,667 shares of our common stock to the holders of phc 's class a common stock and class b common stock based on a one-to-four conversion rate and 19,566,668 phc shares outstanding immediately prior to the acquisition . on april 1 , 2011 , we completed the acquisition of yfcs , the largest private , for-profit provider of behavioral health , education and long-term support services exclusively for abused and neglected children and adolescents , for approximately $ 178.0 million . yfcs operates 13 facilities in eight states and offers a broad array of behavioral programs to adults , adolescents and children . these programs include behavioral acute and residential care in inpatient facilities , therapeutic group homes , therapeutic foster care services , education , and other community based services . this transaction was financed with a $ 135.0 million term loan facility and $ 10 million of borrowings on a $ 30 million revolving credit facility , as well as $ 52.5 million of new equity contributions . the recent acquisitions of facilities and services make us the leading publicly traded pure-play provider of inpatient behavioral healthcare services based upon number of licensed beds in the united states . we believe that the yfcs , phc and haven acquisitions position the combined company as a leading platform in a highly fragmented industry under the direction of an experienced management team that has significant industry expertise . we expect to take advantage of several strategies that are more accessible as a result of our increased size and geographic scale , including implementing a national marketing strategy to attract new patients and referral sources , increasing our volume of out-of-state referrals , providing a broader range of services to new and existing patients and clients and selectively pursuing opportunities to expand our facility and bed count . sources of revenue we receive payments from the following sources , or services rendered in our facilities : ( i ) state governments under their respective medicaid programs and otherwise ; ( ii ) private insurers , including managed care plans ; ( iii ) the federal medicare program ; and ( iv ) directly from other payors including individual patients and clients . for the year ended december 31 , 2011 , on a pro forma basis giving effect to the acquisitions of yfcs and phc , approximately 67 % of our revenue came from medicaid , approximately 20 % came from private insurers , approximately 8 % came from medicare and approximately 5 % came from private pay and other payors . 26 results of operations the following table illustrates our consolidated results of operations from continuing operations for the respective periods shown ( dollars in thousands ) : replace_table_token_3_th year ended december 31 , 2011 compared to the year ended december 31 , 2010 revenue before provision for doubtful accounts . story_separator_special_tag revenue and accounts receivable revenue is derived from services rendered to patients for inpatient psychiatric and substance abuse care , outpatient psychiatric care and adolescent residential treatment and includes revenue payable by the medicare program administered by cms , state medicaid programs , commercial insurance ( in network and out of network ) , and other payors including individual patients . revenue is recorded in the period in which services are provided at established billing rates less contractual adjustments based on amounts reimbursable by medicare or medicaid under provisions of cost or prospective reimbursement formulas or amounts due from other third-party payors at contractually determined rates . the following table presents revenue by payor type and as a percentage of revenue before provision for doubtful accounts for the years ended december 31 , 2010 and 2011 ( in thousands ) : replace_table_token_9_th 32 the following tables present a summary of our aging of accounts receivable as of december 31 , 2011 and 2010 : december 31 , 2011 replace_table_token_10_th december 31 , 2010 replace_table_token_11_th medicaid accounts receivable as of december 31 , 2011 include less than $ 0.5 million of accounts pending medicaid approval . these accounts are aged less than 60 days and are classified as medicaid because we have experienced between 80 % and 90 % approval by medicaid for this class of receivables . allowance for contractual discounts the company derives a significant portion of its revenues from medicare , medicaid and other payors that receive discounts from its established billing rates . the medicare and medicaid regulations and various managed care contracts under which these discounts must be calculated are complex and are subject to interpretation and adjustment , and may include multiple reimbursement mechanisms for different types of services provided in our inpatient facilities and cost settlement provisions . we estimate the allowance for contractual discounts on a payor-specific basis given our interpretation of the applicable regulations or contract terms . the services authorized and provided and related reimbursement are often subject to interpretation that could result in payments that differ from our estimates . additionally , updated regulations and contract renegotiations occur frequently necessitating continual review and assessment of the estimation process by our management . settlements under cost reimbursement agreements with third-party payors are estimated and recorded in the period in which the related services are rendered and are adjusted in future periods as final settlements are determined . final determination of amounts earned under the medicare and medicaid programs often occurs in subsequent years because of audits by such programs , rights of appeal and the application of numerous technical provisions . in the opinion of management , adequate provision has been made for any adjustments and final settlements . however , there can be no assurance that any such adjustments and final settlements will not have a material effect on the company 's financial condition or results of operations . the company 's cost report receivables were $ 0.5 million at december 31 , 2011 compared to cost report payables of $ 0.1 million at december 31 , 2010 , and are included in other current assets and other current liabilities , respectively , in the consolidated balance sheets . the company believes that these receivables and payables are properly stated and are not likely to be settled for a significantly different amount . the net adjustments to estimated cost report settlements resulted in increases to revenue of approximately $ 0.2 million and $ 0.1 million for the years ended december 31 , 2011 and 2010 , respectively . the company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations or wrongdoing . while no such regulatory inquiries have been made , compliance with such laws and regulations can be subject to future government review and interpretation , as well as significant regulatory action including fines , penalties and exclusion from the medicare and medicaid programs . allowance for doubtful accounts our ability to collect outstanding patient receivables from third party payors is critical to our operating performance and cash flows . the primary collection risk with regard to patient receivables relates to uninsured patient accounts or patient accounts for which primary insurance has paid , but the portion owed by the patient remains outstanding . we estimate uncollectible accounts and establish an allowance for doubtful accounts in order to adjust accounts receivable to estimated net realizable value . in evaluating the collectability of accounts receivable , the company considers a number of factors , including the age of the accounts , historical 33 collection experience , current economic conditions , and other relevant factors . accounts receivable that are determined to be uncollectible based on the company 's policies are written off to the allowance for doubtful accounts . significant changes in payor mix or business office operations could have a significant impact on our results of operations and cash flows . insurance we are subject to medical malpractice and other lawsuits due to the nature of the services we provide . we have professional and general liability insurance for claims in excess of a $ 50,000 deductible with an insured excess limit of $ 25 million . the reserve for professional and general liability risks is estimated based on historical claims , demographic factors , industry trends , severity factors , and other actuarial assumptions calculated by an independent third-party actuary . the estimated accrual for professional and general liabilities could be significantly affected should current and future occurrences differ from historical claim trends and expectations . while claims are monitored closely when estimating professional and general liability accruals , the complexity of the claims and wide range of potential outcomes often hampers timely adjustments to the assumptions used in these estimates . the professional and general liability reserve was $ 2.8 million as of december 31 , 2011 , of which $ 1.2
