Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	(a) General
	AMN Healthcare Services, Inc. was incorporated in Delaware on November 10, 1997. AMN Healthcare Services, Inc. and its subsidiaries (collectively, the “Company”) provide healthcare workforce solutions and staffing services at acute and sub-acute care hospitals and other healthcare facilities throughout the United States.
	(b) Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of AMN Healthcare Services, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
	(c) Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to asset impairment, accruals for self-insurance and compensation and related benefits, accounts receivable, contingencies and litigation, and income taxes. The Company bases these estimates on the information that is currently available and on various other assumptions that it believes are reasonable under the circumstances. Actual results could differ from those estimates under different assumptions or conditions.
	(d) Cash and Cash Equivalents
	The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents include currency on hand, deposits with financial institutions and highly liquid investments.
	(e) Restricted Cash, Cash Equivalents and Investments
	Restricted cash, cash equivalents and investments primarily represent the cash and U.S. Treasury securities on deposit with financial institutions that serve as collateral for the Company’s outstanding letters of credit and captive insurance subsidiary claim payments. The original maturity terms for the U.S. Treasury securities were between 3-months and 12-months. See Note (4), “Fair Value Measurement” and Note (8), “Notes Payable and Credit Agreement” for additional information.
	(f) Fixed Assets
	The Company records furniture, equipment, leasehold improvements and internal-use software at cost less accumulated amortization and depreciation. The Company records equipment acquired under capital leases at the present value of the future minimum lease payments. The Company capitalizes major additions and improvements, and expenses maintenance and repairs when incurred. The Company calculates depreciation on furniture, equipment and software using the straight-line method based on the estimated useful lives of the related assets (three to seven years). The Company amortizes leasehold improvements and equipment obtained under capital leases over the shorter of the term of the lease or their estimated useful lives. The Company includes amortization of equipment obtained under capital leases with depreciation expense in the accompanying consolidated financial statements.
	The Company capitalizes costs it incurs to develop internal-use software during the application development stage. Application development stage costs generally include costs associated with internal-use software configuration, coding, installation and testing. The Company also capitalizes costs of significant upgrades and enhancements that result in additional functionality, whereas it expenses as incurred costs for maintenance and minor upgrades and enhancements. The Company amortizes capitalized costs using the straight-line method over three to seven years once the software is ready for its intended use.
	The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to the future undiscounted net cash flows that are expected to be generated by the asset group. If such asset group is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. The Company reports assets to be disposed of at the lower of the carrying amount or fair value less costs to sell.
	(g) Goodwill
	The Company records as goodwill the portion of the purchase price that exceeds the fair value of net assets of entities acquired. The Company evaluates goodwill annually for impairment at the reporting unit level and whenever circumstances occur indicating that goodwill may be impaired. The Company may first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company determines that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, the quantitative impairment test is unnecessary. The performance of the quantitative impairment test involves a two-step process. The first step of the test involves comparing the fair value of the Company’s reporting units with the reporting unit’s carrying amount, including goodwill. The Company generally determines the fair value of its reporting units using a combination of the income approach (using discounted future cash flows) and the market valuation approach. If the carrying amount of the Company’s reporting units exceeds the reporting unit’s fair value, the Company performs the second step of the test to determine the amount of impairment loss. The second step of the test involves comparing the implied fair value of the Company’s reporting unit’s goodwill with the carrying amount of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss.
	(h) Intangible Assets
	Intangible assets consist of identifiable intangible assets acquired through acquisitions. Identifiable intangible assets include tradenames and trademarks, customer relationships, non-compete agreements, staffing databases, acquired technology and online courses. The Company amortizes intangible assets, other than tradenames and trademarks with an indefinite life, using the straight-line method over their useful lives. The Company amortizes non-compete covenants using the straight-line method over the lives of the related agreements. The Company reviews for impairment intangible assets with estimable useful lives whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
	The Company does not amortize indefinite-lived tradenames and trademarks and instead reviews them for impairment annually. The Company may first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, the Company determines that it is more likely than not that the indefinite-lived intangible asset is not impaired, no quantitative fair value measurement is necessary. If a quantitative fair value measurement calculation is required for the indefinite-lived intangible assets, the Company compares the fair value of the Company’s indefinite-lived intangibles with their carrying amount. If the carrying amount exceeds the fair value, the Company records the excess as an impairment loss.
	(i) Insurance Reserves
	The Company maintains an accrual for professional liability that is included in accounts payable and accrued expenses and other long-term liabilities in the consolidated balance sheets. The expense is included in the selling, general and administrative expenses in the consolidated statement of comprehensive income. The Company determines the adequacy of this accrual by evaluating its historical experience and trends, loss reserves established by the Company’s insurance carriers, management and third-party administrators, and its independent actuarial studies. The Company obtains actuarial studies on a semi-annual basis that use the Company’s actual claims data and industry data to assist the Company in determining the adequacy of its reserves each year. For periods between the actuarial studies, the Company records its accruals based on loss rates provided in the most recent actuarial study and management's review of loss history. In November 2012, the Company established a captive insurance subsidiary, which provides coverage, on an occurrence basis, for professional liability within its nurse and allied healthcare staffing segment. Liabilities include provisions for estimated losses incurred but not yet reported (“IBNR”), as well as provisions for known claims. IBNR reserve estimates involve the use of assumptions and are primarily based upon historical loss experience, industry data and other actuarial assumptions. The Company maintains excess insurance coverage through a commercial carrier for losses above the per occurrence retention.
	The Company maintains an accrual for workers compensation, which is included in accrued compensation and benefits and other long-term liabilities in the consolidated balance sheets. The Company determines the adequacy of this accrual by evaluating its historical experience and trends, loss reserves established by the Company’s insurance carriers and third-party administrators, and its independent actuarial studies. The Company obtains actuarial studies on a semi-annual basis that use the Company’s payroll and historical claims data, as well as industry data, to determine the appropriate reserve for both reported claims and IBNR claims for each policy year. For periods between the actuarial studies, the Company records its accruals based on loss rates provided in the most recent actuarial study.
	(j) Revenue Recognition
	Revenue consists of fees earned from the permanent and temporary placement of healthcare professionals. Revenue is recognized when earned and realizable. The Company has entered into certain contracts with healthcare organizations to provide managed services programs. Under these contract arrangements, the Company uses its healthcare professionals along with those of third-party subcontractors to fulfill client orders. If the Company uses subcontractors, it records revenue net of related subcontractors expense. The resulting net revenue represents the administrative fee the Company charges for its vendor management services. The Company is liable to the subcontractor after it receives payment from the client. The Company includes payables to subcontractors in accounts payable and accrued expenses in the consolidated balance sheets.
	(k) Accounts Receivable
	The Company records accounts receivable at the invoiced amount. Accounts receivable are non-interest bearing. The Company maintains an allowance for doubtful accounts for estimated credit losses resulting from collection risk, including the inability of customers to make required payments under contractual agreements. The allowance for doubtful accounts is reported as a reduction of accounts receivable in the consolidated balance sheets. The Company determines the adequacy of this allowance by evaluating historical delinquency and write-off trends, the financial condition and credit risk and history of each customer, historical payment trends as well as current economic conditions and the impact of such conditions on the customers’ liquidity and overall financial condition. The Company also maintains a sales allowance to reserve for potential credits issued to customers. The Company determines the amount of the reserve based on historical credits issued.
	(l) Concentration of Credit Risk
	The majority of the Company’s business activity is with hospitals located throughout the United States. Credit is extended based on the evaluation of each entity’s financial condition, and collateral is generally not required. Credit losses have been within management’s expectations. Other than one healthcare system, which comprised approximately 10% of the consolidated revenue of the Company for the fiscal year ended December 31, 2014, no client healthcare system exceeded 10% of consolidated revenue for the years ended December 31, 2014, 2013 or 2012. As of each of December 31, 2014 and 2013, accounts receivable from the Company’s top five clients represented approximately 12% of the net accounts receivable balance, excluding amounts due to subcontractors.
	The Company’s cash and cash equivalents and restricted cash, cash equivalents and investments accounts are also financial instruments that are exposed to concentration of credit risk. The Company maintains its cash balances with high-credit quality and federally insured institutions. Cash balances may be invested in a non-federally insured money market account. As of December 31, 2014 and 2013, there were $19,567 and $23,115, respectively, of restricted cash, cash equivalents and investments primarily invested in a non-federally insured U.S. Treasury security account.
	(m) Income Taxes
	The Company records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. 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 the period the changes are enacted. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. The Company recognizes the effect of income tax positions only if it is more likely than not that such positions will be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.
	(n) Fair Value of Financial Instruments
	The carrying amounts of the Company’s cash equivalents and restricted cash equivalents approximate their respective fair values due to the short-term nature and liquidity of these financial instruments. The carrying amount of the Company’s notes payable approximates its fair value as the Company refinanced its credit facilities in 2014 and the instrument’s interest rates are variable (significant other observable inputs - level 2). See Note (8), “Notes Payable and Credit Agreement,” for additional information. The fair value of the long-term portion of the Company’s insurance accruals cannot be estimated as the Company cannot reasonably determine the timing of future payments.
	(o) Share-Based Compensation
	The Company accounts for its share-based employee compensation plans by expensing the estimated fair value of share-based awards on a straight-line basis over the requisite employee service period, which is the vesting period. Restricted stock units (“RSUs”) granted under the Equity Plan (as defined in Note (11), “Share-Based Compensation”) typically vest at the end of a three-year vesting period, however, 33% of the awards may vest on the 13th month anniversary of the grant date, and 34% on the second anniversary of the grant date, if certain performance targets are met. Share-based compensation cost of RSUs is measured by the market value of the Company’s common stock on the date of grant. Performance restricted stock units (“PRSUs”) granted under the Equity Plan typically consist of 1) PRSUs that contain a market condition with the ultimate realizable number of PRSUs dependent on relative and absolute total shareholder return over a three-year period, up to a maximum amount to be issued under the award of 175% of the original grant (“TSR PRSUs”), the fair values of which are estimated using the Monte-Carlo simulation valuation model and will not be adjusted for the achievement, or lack thereof, of the performance conditions; and 2) PRSUs that contain a performance condition, with the ultimate realizable number of PRSUs dependent on the adjusted EBITDA margin performance of the Company during a certain annual performance period, with a range of 0% to 175% of the target amount granted to be issued under the award. Share-based compensation cost for EBITDA margin PRSUs is measured by the market value of the Company’s common stock on the date of grant, and will be adjusted for estimated achievement of the performance conditions. Stock options and stock appreciation rights granted are measured on the date of grant using the Black-Scholes valuation model, which includes assumptions such as expected term of the award, stock price volatility, dividend rate and risk free interest rate. The Company also estimates the forfeiture rate and records share-based compensation expense only for those awards that are expected to vest.
	(p) Net Income per Common Share
	Securities that are entitled to participate in dividends with common stock, such as the Company’s Series A Conditional Convertible Preferred Stock (the “Preferred Stock”), are considered to be participating securities and the two-class method is used for purposes of calculating basic net income per share. Under the two-class method, a portion of net income is allocated to participating securities and excluded from the calculation of basic net income per common share. On December 21, 2012, all outstanding shares of Preferred Stock were converted into common stock; accordingly, for the two-class method calculation, the net income was allocated between common stock and Preferred Stock on a proportionate basis using a systematic and reasonable basis (based on number of days outstanding) for purpose of calculating the basic net income per share for the year ended December 31, 2012.
	Share-based awards to purchase 298, 308 and 1,902 shares of common stock for the years ended December 31, 2014, 2013 and 2012, respectively, were not included in the calculation of diluted net income per common share because the effect of these instruments was anti-dilutive.
	The following table sets forth the computation of basic and diluted net income per common share for the years ended December 31, 2014, 2013 and 2012, respectively:
		Years Ended December 31,
		2014		2013		2012

	Weighted average common shares outstanding—diluted	48,086		47,787		46,709
	(q) Discontinued Operations
	The results of operations of a disposal group held for sale or disposed is presented as discontinued operations when the underlying operations and cash flows of the disposal group will be, or have been, eliminated from the Company’s continuing operations and the Company no longer has the ability to influence the operating and/or financial policies of the disposal group. This assessment is made at the time the disposal group is classified as held for sale and for a one-year period after the sale of the disposal group. See Note (2), “Discontinued Operations,” for further information regarding the Company’s discontinued operations.
	(r) Segment Information
	Historically, the Company had four reportable segments: nurse and allied healthcare staffing, locum tenens staffing, physician permanent placement services and home healthcare services. During the fourth quarter of 2011, the Company announced the expected divestiture of its home healthcare services segment, which was completed in January 2012. As a result, the home healthcare services segment was classified as disposal group held for sale as of December 31, 2011, and its results of operations have been classified as discontinued operations for the year ended December 31, 2012.
The Company’s management relies on internal management reporting processes that provide revenue and operating income by reportable segment for making financial decisions and allocating resources. Segment operating income represents income before income taxes plus depreciation, amortization of intangible assets, share-based compensation expense, interest expense (net) and other, and unallocated corporate overhead. The Company’s management does not evaluate, manage or measure performance of segments using asset information; accordingly, asset information by segment is not prepared or disclosed.
The following table provides a reconciliation of revenue and segment operating income by reportable segment to consolidated results and was derived from each segment’s internal financial information as used for corporate management purposes:
	Years Ended December 31,

(s) Reclassifications
Certain reclassifications have been made to certain of the prior years’ consolidated financial statements to conform to the current year presentation. Specifically, 1) payments made into the Company’s life insurance policies to assist in funding the deferred compensation plan were reclassified from cash flows from operating activities to cash flows from investing activities; and 2) changes in book overdraft were reclassified from cash flows from financing activities to changes in accounts payable and accrued expenses within cash flows from operating activities in the consolidated statement of cash flows for both the year ended December 31, 2013 and 2012. In addition, the Company reclassified expected insurance recoveries under its professional liability and workers compensation policies in the consolidated balance sheet for the year ended December 31, 2013 to conform to the current year presentation. Professional liability and workers compensation liabilities were previously presented net of insurance recoveries. For the fiscal year ended December 31, 2014, expected insurance recoveries are presented on a gross basis, with the short-term insurance receivable portion included within “Prepaid and other current assets” and the long-term portion included within “Other assets” on the consolidated balance sheet.

	Avantas Acquisition
	On December 22, 2014, the Company completed its acquisition of Avantas, a leading provider of clinical labor management services, including workforce consulting, data analytics, predictive modeling and SaaS-based scheduling technology. The acquisition is intended to help enable the Company to provide a level of workforce predictability to clients that can be integrated with its workforce and staffing solutions. The acquisition is not considered a material business combination and, accordingly, pro forma information is not provided. The acquisition was funded through cash-on-hand and borrowings under the Company’s Revolver (as defined in Note (8), “Notes Payable and Credit Agreement”). The Company did not incur any material acquisition-related costs.
	The Company accounted for the acquisition using the acquisition method of accounting and, accordingly, it recorded the tangible and intangible assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition. The total purchase price of $17,520 included $14,470 cash consideration paid, $1,650 cash holdback for potential claims indemnified by the Avantas shareholders and contingent earn-out with a fair value of $1,400. The acquisition agreement provides for a contingent earn-out payment of up to $8,500 to be paid in 2016 based on future operating performance. As of the date of this Annual Report on Form 10-K, the Company is still finalizing the allocation of the purchase price. The provisional items pending finalization are primarily related to tax matters, which the Company expects to complete during 2015.
	The preliminary allocation of the purchase price consisted of $1,631 of fair value of tangible assets acquired, $3,821 of liabilities and deferred revenue assumed, $9,750 of goodwill and $9,960 of identified intangible assets. The intangible assets include the fair value of tradenames and trademarks, customer relationships and acquired technologies. The weighted average useful life of the acquired intangible assets subject to amortization is approximately 14 years. All goodwill recognized from this acquisition is deductible for tax purposes.
	The results of operations of Avantas are included in the nurse and allied healthcare staffing segment in the Company’s consolidated financial statements since the date of acquisition.
	ShiftWise Acquisition
	On November 20, 2013, the Company completed its acquisition of ShiftWise, a leading national provider of web-based healthcare workforce solutions, including its VMS technology utilized by hospitals and other healthcare systems. The acquisition is not considered a material business combination and, accordingly, pro forma information is not provided. The acquisition was funded through cash-on-hand and the Company did not incur any material acquisition-related costs.
	The Company accounted for the acquisition using the acquisition method of accounting and, accordingly, it recorded the tangible and intangible assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition. The purchase price of the acquisition totaled $39,500, of which $6,000 was deposited in escrow to satisfy any indemnification claims by the Company with respect to, among other customary items, breaches of representations, warranties and covenants by ShiftWise and post-closing purchase price adjustments. The $6,000 deposited in escrow is scheduled to be disbursed to the selling shareholders in three years following the closing date at $2,000 per annum minus any indemnification claims. In November 2014, $132 cash was released from escrow to the Company, and $1,568 cash was released from escrow to the former Shiftwise shareholders, under the terms of the acquisition agreement.
	The allocation of the purchase price consisted of $9,899 of fair value of tangible assets acquired, $11,502 of liabilities assumed (including $2,701 of deferred tax liabilities), $21,313 of goodwill and $19,790 of identified intangible assets. The intangible assets include the fair value of tradenames and trademarks, customer relationships, non-compete agreements and acquired technologies. The weighted average useful life of the acquired intangible assets subject to amortization is approximately 8 years. There is no goodwill recognized as part of this acquisition that is deductible for tax purposes.
	The results of operations of ShiftWise are included in the nurse and allied healthcare staffing segment in the Company’s consolidated financial statements since the date of acquisition.
	Pipeline Equity Investment
	In March 2014, the Company entered into an agreement (the “Pipeline Agreement”) under which it made an initial $2,000 investment in Pipeline Health Holdings LLC (“Pipeline”), a telepharmacy and pharmacy technology solutions provider. The Company’s ownership percentage in Pipeline at March 31, 2014 was approximately 9%. Under the Pipeline Agreement, the Company committed to invest up to an additional $3,000 contingent upon Pipeline reaching two milestone commitments within a year. In April and September 2014, the Company made the milestone investments of $1,000 and $2,000, respectively, which together with the initial investment represents an ownership percentage in Pipeline of approximately 18% as of December 31, 2014. The investment is accounted for under the equity method of accounting. The Company’s share of Pipeline’s results is included within “Interest expense, net, and other” in the accompanying audited consolidated statement of comprehensive income for the year ended December 31, 2014.

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement
	Fair value represents the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which the Company would conduct a transaction, in addition to the assumptions that market participants would use when pricing the related assets or liabilities, including non-performance risk.
	A three-level hierarchy prioritizes the inputs to valuation techniques used to measure fair value and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the fair value hierarchy are as follows:
	Level 1—Quoted prices in active markets for identical assets or liabilities.
	Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Assets and Liabilities Measured on a Recurring Basis
	The Company’s assets that are measured at fair value on a recurring basis include restricted cash equivalents and investments.
	In addition, with the recent acquisition of Avantas, the Company has an obligation to pay earn-out consideration of up to $8,500 in cash, to the former selling shareholders, if certain future financial metrics are met by Avantas. The earn-out payment is expected to be determined in the second half of 2016. Expected cash flows are determined using the probability-weighted average of possible outcomes that would occur should certain financial metrics be reached. There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of Avantas to evaluate the fair value of this liability. As such, the contingent consideration is classified within Level 3.
	In connection with estimating the fair value of the contingent consideration, the Company estimates the weighted probability of Avantas earning each of the five specified tiered earn-out amounts of $0, $1,500, $3,500, $5,500 and $8,500, which are each tied to the financial performance of Avantas during the year ending June 30, 2016. An increase or decrease in the probability of achievement of an earn-out tier will result in an increase or decrease to the estimated fair value of the contingent consideration. The Company will reassess the fair value each reporting period and adjust the liability to its then fair value.
	The following tables present information about these assets and liabilities and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value:

	The Company’s restricted cash equivalents and investments typically consist of U.S. Treasury securities and money market funds on deposit with financial institutions that serve as collateral for the Company’s outstanding letters of credit.
	Assets Measured on a Non-Recurring Basis
	The Company applies fair value techniques on a non-recurring basis associated with valuing potential impairment losses related to its goodwill, indefinite-lived intangible assets, long-lived assets and equity method investment.
	The Company evaluates goodwill at the reporting unit level and indefinite-lived intangible assets annually for impairment and whenever circumstances occur indicating that goodwill might be impaired. The Company determines the fair value of its reporting units based on a combination of inputs including the market capitalization of the Company as well as Level 3 inputs such as discounted cash flows, which are not observable from the market, directly or indirectly. The Company determined the fair value of its indefinite-lived intangible assets using the income approach (relief-from-royalty method) based on Level 3 inputs.
	The Company performed its annual impairment testing at each of October 31, 2014, 2013 and 2012, and determined there was no impairment of goodwill or its indefinite-lived intangibles. See Note (5), “Goodwill and Identifiable Intangible Assets” for additional information.

	In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management believes it is more likely than not that the Company will realize the benefits of its deferred tax assets, net of the recorded valuation allowance.
	The deferred tax assets related to net operating losses (“NOLs”) include NOLs from the 2010 NFI and 2013 ShiftWise acquisitions. The amount of NOL from acquired companies has been the subject of an evaluation under the NOL limitation rules of Internal Revenue Code (“IRC”) Section 382 and corresponding state authorities and the balances reflect these limitations.
	The amount of federal NOL carryforward that is available for use in years subsequent to December 31, 2014 is $31,364, which is set to expire by 2029. The amount of state NOL carryforward that is available for use in years subsequent to December 31, 2014 is $47,688, which is set to expire at various dates between 2015 and 2032.
	A summary of the changes in the amount of unrecognized tax benefits (excluding interest and penalties) for 2014, 2013 and 2012 is as follows:
		2014			2013			2012
	Beginning balance of unrecognized tax benefits	$	22,573		$	21,415		$	21,221
	Additions based on tax positions related to the current year	—			809			1,096
	Additions based on tax positions of prior years	317			349			—
	Reductions due to lapse of applicable statute of limitation	—			—			(902		)
	Ending balance of unrecognized tax benefits	$	22,890		$	22,573		$	21,415
	At December 31, 2014, if recognized, approximately $25,056 would affect the effective tax rate (including interest and penalties).
	The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company has approximately $5,815, $4,605 and $3,178 of accrued interest and penalties related to unrecognized tax benefits at December 31, 2014, 2013 and 2012, respectively. The amount of interest and penalties recognized in 2014, 2013 and 2012 were $1,211, $1,427 and $468, respectively.
	The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. With few exceptions, as of December 31, 2014, the Company is no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2005. The Internal Revenue Service (“IRS”) completed its tax audit of the Company for the years 2007, 2008, 2009 and 2010, and issued a Revenue Agent Report (“RAR”) to the Company related to its completed tax examination. The RAR seeks adjustments to the Company’s taxable income for 2007-2010 and net operating loss carryforwards from 2005-2006. The adjustments to the Company’s taxable income relate to the proposed disallowance of certain per diems paid to our healthcare professionals. Concurrent with the RAR, the Company received an Employment Tax Examination Report (“ETER”) for 2009 and 2010. The ETER adjustments propose additional Company payroll tax liabilities and penalties related to the treatment of certain non-taxable per diem allowances and travel benefits. The positions in the RAR and ETER are mutually exclusive. The RAR and ETER contain multiple tax positions, some of which are contrary to each other. The Company has filed a Protest Letter for both the RAR and ETER and intends to defend its position. The Company has held several meetings with the IRS Appeals office throughout 2014. The Company does expect resolution of these matters within the next twelve months but cannot predict with certainty the timing of such resolution or an estimated settlement amount. However, the Company believes its reserves will be adequate to cover the anticipated settlement. Notwithstanding, the Company could adjust its provision for income taxes and/or contingent tax liability based on future developments.
	The IRS began a separate 2011-2012 income and payroll tax audit during November 2013 and has recently completed its field work. We are awaiting the IRS exam report but do not expect the issues to be different than the issues raised in the last exam. The Company believes its reserve for unrecognized tax benefits and contingent tax issues is adequate with respect to all open years.

Notes Payable and Credit Agreement	Notes Payable and Credit Agreement
	On April 18, 2014, the Company entered into a Credit Agreement (the “Credit Agreement”) with several lenders to provide for two credit facilities (the “New Credit Facilities”) to replace its prior credit facilities, including (A) a $225,000 secured revolving credit facility (the “Revolver”) that includes a $40,000 sublimit for the issuance of letters of credit and a $20,000 sublimit for swingline loans and (B) a $150,000 secured term loan credit facility (the “Term Loan”). In addition, the Credit Agreement provides that the Company may from time to time obtain an increase in the Revolver or the Term Loan or both in an aggregate principal amount not to exceed $125,000 subject to, among other conditions, the arrangement of additional commitments with financial institutions reasonably acceptable to the Company and the administrative agent.
	The Revolver carries an unused fee of 0.25% to 0.35% per annum and each standby letter of credit issued under the Revolver is subject to a letter of credit fee ranging from 1.50% to 2.25% per annum of the average daily maximum amount available to be drawn under the standby letter of credit, in each case, depending on the Company’s consolidated leverage ratio, as calculated quarterly in accordance with the Credit Agreement. The Term Loan is subject to amortization of principal of 5.00% per year of the original Term Loan amount, which is $7,500 per annum, and payable in equal quarterly installments. Borrowings under the Term Loan and Revolver bear interest at floating rates, at the Company’s option, based upon either LIBOR plus a spread of 1.50% to 2.25% or a base rate plus a spread of 0.50% to 1.25%. The applicable spread is determined quarterly based upon the Company’s consolidated leverage ratio, as calculated quarterly in accordance with the Credit Agreement. The interest rate for the outstanding Term Loan was 1.9% on a LIBOR basis and the interest rate for the outstanding Revolver was 4.0% on a base rate basis as of December 31, 2014.
	The Company used the proceeds from the New Credit Facilities to repay in full all outstanding indebtedness under its prior credit facilities and to pay related transaction costs.
	In connection with obtaining the New Credit Facilities, the Company incurred $3,488 in fees paid to lenders and other third parties, which were capitalized and are amortized to interest expense over the term of the New Credit Facilities. In addition, the Company wrote off $3,113 of unamortized financing fees and original issue discount, which was recorded as loss on debt extinguishment in the accompanying consolidated statement of comprehensive income for the year ended December 31, 2014.
	The New Credit Facilities are available for working capital, capital expenditures, permitted acquisitions and general corporate purposes of the Company. The maturity date of the New Credit Facilities is April 18, 2019. At December 31, 2014, the outstanding balance of the Term Loan was $144,375, of which $7,500 is due in the next 12 months, and there was $18,000 outstanding under the Revolver. At December 31, 2014, with $9,380 of outstanding letters of credit collaterialized by the Revolver, there was $197,620 of available credit under the Revolver.
	Annual principal maturities of the Term Loan are as follows:
	Year ending December 31, 2015	$	7,500
	Year ending December 31, 2016	7,500
	Year ending December 31, 2017	7,500
	Year ending December 31, 2018	7,500
	Thereafter	114,375
		$	144,375
	The Company’s outstanding debt instruments at December 31, 2014 and 2013 were secured by substantially all of the assets of the Company and the common stock or equity interests of its domestic subsidiaries.
	The Credit Agreement contains various customary affirmative and negative covenants, including restrictions on assumption of additional indebtedness, declaration and payment of dividends, dispositions of assets, consolidation into another entity and allowable investments. It also contains financial covenants that require the Company (1) not to exceed a certain maximum consolidated leverage ratio, as calculated in accordance with the Credit Agreement, which is initially set at 4.00 to 1.00 but ultimately steps down to 3.50 to 1.00 beginning with the fiscal quarter ending June 30, 2016, and (2) to maintain a minimum consolidated interest coverage ratio of 2.50 to 1.00, as calculated in accordance with the Credit Agreement.
	Letters of Credit
	At December 31, 2014, the Company maintained outstanding standby letters of credit totaling $15,006 as collateral in relation to its professional liability insurance agreements, workers compensation insurance agreements, and a corporate office lease agreement. Of the $15,006 outstanding letters of credit, the Company has collateralized $5,626 in cash, cash equivalents and investments and the remaining amount has been collateralized by the Revolver. Outstanding standby letters of credit at December 31, 2013 totaled $27,691.

	(a) Equity Award Plans
	Stock Option Plan
	The Company established a stock option plan (the “Stock Option Plan”) to provide a means to attract and retain employees. 4,178 options were authorized for issuance to be granted under the Stock Option Plan. Unless otherwise provided at the time of the grant, the options vest and become exercisable in increments of 25% on each of the first four anniversaries of the date of grant. Options granted under the Stock Option Plan expire on the tenth anniversary of the grant date. On April 12, 2006, 371 shares of common stock reserved for future issuance under The Stock Option Plan were rolled into the Equity Plan, which is discussed below. There will be no further equity awards granted from the Stock Option Plan.
	Equity Plan
	The Company established the AMN Healthcare Equity Plan (as amended or amended and restated from time to time, the “Equity Plan”), which has been approved by the Company’s stockholders. At the time of the Equity Plan’s adoption in 2006, equity awards, based on the Company’s common stock, could be issued for a maximum of 723 shares plus the number of shares of common stock underlying any grants under the Stock Option Plan that are forfeited, canceled or terminated (other than by exercise) from and after the effective date of the Equity Plan. Pursuant to the Equity Plan, stock options and stock appreciation rights (“SARs”) granted have a maximum contractual life of ten years and exercise prices will be determined at the time of grant and will be no less than fair market value of the underlying common stock on the date of grant. Any shares to be issued under the Equity Plan will be issued by the Company from authorized but unissued common stock or shares of common stock reacquired by the Company. On April 18, 2007, April 9, 2009 and April 18, 2012, the Company amended the Equity Plan, with stockholder approval, to increase the number of shares authorized under the Equity Plan by 3,000, 1,850 and 2,400, respectively. At December 31, 2014 and 2013, respectively, 2,421 and 2,173 shares of common stock were reserved for future grants under the Equity Plan.
	Other Plans
	From time to time, we grant, and have granted, key employees inducement awards outside of the Equity Plan (collectively, “Other Plans”), which have consisted of SARs,options orRSUs, which generally have three-year cliff vesting with a potential for accelerated vesting based on the Company’s achievement of selected targeted financial performance. Although these awards are not made under the Equity Plan, the key terms and conditions of the grant are typically the same as equity awards made under the Equity Plan.
	Additionally, in February 2014, the Company established the 2014 Employment Inducement Plan, which reserves for issuance 200 shares of common stock for prospective employees of the Company. As of December 31, 2014, 200 shares of common stock remained available for future grants under the 2014 Employment Inducement Plan.
	(b) Share-Based Compensation
	Restricted Stock Units
	RSUs granted under the Equity Plan generally entitle the holder to receive, at the end of a vesting period, a specified number of shares of the Company’s common stock.
	The following table summarizes RSU and PRSU activity for non-vested awards for the years ended December 31, 2014, 2013 and 2012:

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	(a) Legal
	From time to time, the Company is involved in various lawsuits, claims, investigations, and proceedings that arise in the ordinary course of business. Additionally, some of its clients may also become subject to claims, governmental inquiries and investigations and legal actions relating to services provided by the Company’s healthcare professionals. From time to time, and depending upon the particular facts and circumstances, the Company may be subject to indemnification obligations under its contracts with such clients relating to these matters. Certain of above-referenced matters may include speculative claims for substantial or indeterminate amounts of damages. The Company records a liability when management believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions at least quarterly and adjusts them accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. During the first quarter of 2014, the Company completed the settlement of a wage and hour class action (and a related action) for an immaterial amount. With regards to outstanding loss contingencies as of December 31, 2014, the Company believes that the amount or estimable range of reasonably possible loss, will not, either individually or in the aggregate, have a material adverse effect on its business, consolidated financial position, results of operations or cash flows. However, the outcome of litigation is inherently uncertain, and therefore, if one or more of these legal matters were resolved against the Company for amounts in excess of management’s expectations, the Company’s results of operations and financial condition, including in a particular reporting period, could be materially adversely affected.
	(b) Leases
	The Company leases certain office facilities and equipment under various operating leases. The Company recognizes rent expense on a straight-line basis over the lease term. Future minimum lease payments under noncancelable operating leases (with initial or remaining lease terms in excess of one year) as of December 31, 2014 are as follows:
		Operating

	2018	11,662
	2019	11,783
	Thereafter	92,949
	Total minimum lease payments	$	155,666
	On January 26, 2015, the Company entered into a 10-year operating lease agreement for office space in Dallas, Texas that will replace its current operating lease agreement for its Irving, Texas offices, which expires in August 2015. Base rent payments under the new lease agreement will begin in September 2015 and the total estimated base rent payments will be approximately $23,956 over the life of the lease, which has been included in the above total minimum lease payments table.
	Rent expense under operating leases for continuing operations was $14,136, $14,205, and $15,187 for the years ended December 31, 2014, 2013 and 2012, respectively.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	The accompanying consolidated financial statements include the accounts of AMN Healthcare Services, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to asset impairment, accruals for self-insurance and compensation and related benefits, accounts receivable, contingencies and litigation, and income taxes. The Company bases these estimates on the information that is currently available and on various other assumptions that it believes are reasonable under the circumstances. Actual results could differ from those estimates under different assumptions or conditions.
Cash and Cash Equivalents	The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents include currency on hand, deposits with financial institutions and highly liquid investments.
Restricted Cash, Cash Equivalents and Investments	Restricted cash, cash equivalents and investments primarily represent the cash and U.S. Treasury securities on deposit with financial institutions that serve as collateral for the Company’s outstanding letters of credit and captive insurance subsidiary claim payments. The original maturity terms for the U.S. Treasury securities were between 3-months and 12-months.
Fixed Assets	The Company records furniture, equipment, leasehold improvements and internal-use software at cost less accumulated amortization and depreciation. The Company records equipment acquired under capital leases at the present value of the future minimum lease payments. The Company capitalizes major additions and improvements, and expenses maintenance and repairs when incurred. The Company calculates depreciation on furniture, equipment and software using the straight-line method based on the estimated useful lives of the related assets (three to seven years). The Company amortizes leasehold improvements and equipment obtained under capital leases over the shorter of the term of the lease or their estimated useful lives. The Company includes amortization of equipment obtained under capital leases with depreciation expense in the accompanying consolidated financial statements.
	The Company capitalizes costs it incurs to develop internal-use software during the application development stage. Application development stage costs generally include costs associated with internal-use software configuration, coding, installation and testing. The Company also capitalizes costs of significant upgrades and enhancements that result in additional functionality, whereas it expenses as incurred costs for maintenance and minor upgrades and enhancements. The Company amortizes capitalized costs using the straight-line method over three to seven years once the software is ready for its intended use.
	The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to the future undiscounted net cash flows that are expected to be generated by the asset group. If such asset group is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. The Company reports assets to be disposed of at the lower of the carrying amount or fair value less costs to sell.
Goodwill	The Company records as goodwill the portion of the purchase price that exceeds the fair value of net assets of entities acquired. The Company evaluates goodwill annually for impairment at the reporting unit level and whenever circumstances occur indicating that goodwill may be impaired. The Company may first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company determines that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, the quantitative impairment test is unnecessary. The performance of the quantitative impairment test involves a two-step process. The first step of the test involves comparing the fair value of the Company’s reporting units with the reporting unit’s carrying amount, including goodwill. The Company generally determines the fair value of its reporting units using a combination of the income approach (using discounted future cash flows) and the market valuation approach. If the carrying amount of the Company’s reporting units exceeds the reporting unit’s fair value, the Company performs the second step of the test to determine the amount of impairment loss. The second step of the test involves comparing the implied fair value of the Company’s reporting unit’s goodwill with the carrying amount of that goodwill. The amount by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss.
Intangible Assets	Intangible assets consist of identifiable intangible assets acquired through acquisitions. Identifiable intangible assets include tradenames and trademarks, customer relationships, non-compete agreements, staffing databases, acquired technology and online courses. The Company amortizes intangible assets, other than tradenames and trademarks with an indefinite life, using the straight-line method over their useful lives. The Company amortizes non-compete covenants using the straight-line method over the lives of the related agreements. The Company reviews for impairment intangible assets with estimable useful lives whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
	The Company does not amortize indefinite-lived tradenames and trademarks and instead reviews them for impairment annually. The Company may first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, the Company determines that it is more likely than not that the indefinite-lived intangible asset is not impaired, no quantitative fair value measurement is necessary. If a quantitative fair value measurement calculation is required for the indefinite-lived intangible assets, the Company compares the fair value of the Company’s indefinite-lived intangibles with their carrying amount. If the carrying amount exceeds the fair value, the Company records the excess as an impairment loss.
Insurance Reserves	The Company maintains an accrual for professional liability that is included in accounts payable and accrued expenses and other long-term liabilities in the consolidated balance sheets. The expense is included in the selling, general and administrative expenses in the consolidated statement of comprehensive income. The Company determines the adequacy of this accrual by evaluating its historical experience and trends, loss reserves established by the Company’s insurance carriers, management and third-party administrators, and its independent actuarial studies. The Company obtains actuarial studies on a semi-annual basis that use the Company’s actual claims data and industry data to assist the Company in determining the adequacy of its reserves each year. For periods between the actuarial studies, the Company records its accruals based on loss rates provided in the most recent actuarial study and management's review of loss history. In November 2012, the Company established a captive insurance subsidiary, which provides coverage, on an occurrence basis, for professional liability within its nurse and allied healthcare staffing segment. Liabilities include provisions for estimated losses incurred but not yet reported (“IBNR”), as well as provisions for known claims. IBNR reserve estimates involve the use of assumptions and are primarily based upon historical loss experience, industry data and other actuarial assumptions. The Company maintains excess insurance coverage through a commercial carrier for losses above the per occurrence retention.
	The Company maintains an accrual for workers compensation, which is included in accrued compensation and benefits and other long-term liabilities in the consolidated balance sheets. The Company determines the adequacy of this accrual by evaluating its historical experience and trends, loss reserves established by the Company’s insurance carriers and third-party administrators, and its independent actuarial studies. The Company obtains actuarial studies on a semi-annual basis that use the Company’s payroll and historical claims data, as well as industry data, to determine the appropriate reserve for both reported claims and IBNR claims for each policy year. For periods between the actuarial studies, the Company records its accruals based on loss rates provided in the most recent actuarial study.
Revenue Recognition	Revenue consists of fees earned from the permanent and temporary placement of healthcare professionals. Revenue is recognized when earned and realizable. The Company has entered into certain contracts with healthcare organizations to provide managed services programs. Under these contract arrangements, the Company uses its healthcare professionals along with those of third-party subcontractors to fulfill client orders. If the Company uses subcontractors, it records revenue net of related subcontractors expense. The resulting net revenue represents the administrative fee the Company charges for its vendor management services. The Company is liable to the subcontractor after it receives payment from the client.
Accounts Receivable	The Company records accounts receivable at the invoiced amount. Accounts receivable are non-interest bearing. The Company maintains an allowance for doubtful accounts for estimated credit losses resulting from collection risk, including the inability of customers to make required payments under contractual agreements. The allowance for doubtful accounts is reported as a reduction of accounts receivable in the consolidated balance sheets. The Company determines the adequacy of this allowance by evaluating historical delinquency and write-off trends, the financial condition and credit risk and history of each customer, historical payment trends as well as current economic conditions and the impact of such conditions on the customers’ liquidity and overall financial condition. The Company also maintains a sales allowance to reserve for potential credits issued to customers. The Company determines the amount of the reserve based on historical credits issued.
Concentration of Credit Risk	The Company’s cash and cash equivalents and restricted cash, cash equivalents and investments accounts are also financial instruments that are exposed to concentration of credit risk. The Company maintains its cash balances with high-credit quality and federally insured institutions. Cash balances may be invested in a non-federally insured money market account.
	The majority of the Company’s business activity is with hospitals located throughout the United States. Credit is extended based on the evaluation of each entity’s financial condition, and collateral is generally not required. Credit losses have been within management’s expectations.
Income Taxes	The Company records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. 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 the period the changes are enacted. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected future taxable income, and tax-planning strategies in making this assessment. The Company recognizes the effect of income tax positions only if it is more likely than not that such positions will be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.
Fair Value of Financial Instruments	The carrying amounts of the Company’s cash equivalents and restricted cash equivalents approximate their respective fair values due to the short-term nature and liquidity of these financial instruments. The carrying amount of the Company’s notes payable approximates its fair value as the Company refinanced its credit facilities in 2014 and the instrument’s interest rates are variable (significant other observable inputs - level 2). See Note (8), “Notes Payable and Credit Agreement,” for additional information. The fair value of the long-term portion of the Company’s insurance accruals cannot be estimated as the Company cannot reasonably determine the timing of future payments.
Share-Based Compensation	The Company accounts for its share-based employee compensation plans by expensing the estimated fair value of share-based awards on a straight-line basis over the requisite employee service period, which is the vesting period. Restricted stock units (“RSUs”) granted under the Equity Plan (as defined in Note (11), “Share-Based Compensation”) typically vest at the end of a three-year vesting period, however, 33% of the awards may vest on the 13th month anniversary of the grant date, and 34% on the second anniversary of the grant date, if certain performance targets are met. Share-based compensation cost of RSUs is measured by the market value of the Company’s common stock on the date of grant. Performance restricted stock units (“PRSUs”) granted under the Equity Plan typically consist of 1) PRSUs that contain a market condition with the ultimate realizable number of PRSUs dependent on relative and absolute total shareholder return over a three-year period, up to a maximum amount to be issued under the award of 175% of the original grant (“TSR PRSUs”), the fair values of which are estimated using the Monte-Carlo simulation valuation model and will not be adjusted for the achievement, or lack thereof, of the performance conditions; and 2) PRSUs that contain a performance condition, with the ultimate realizable number of PRSUs dependent on the adjusted EBITDA margin performance of the Company during a certain annual performance period, with a range of 0% to 175% of the target amount granted to be issued under the award. Share-based compensation cost for EBITDA margin PRSUs is measured by the market value of the Company’s common stock on the date of grant, and will be adjusted for estimated achievement of the performance conditions. Stock options and stock appreciation rights granted are measured on the date of grant using the Black-Scholes valuation model, which includes assumptions such as expected term of the award, stock price volatility, dividend rate and risk free interest rate. The Company also estimates the forfeiture rate and records share-based compensation expense only for those awards that are expected to vest.
Net Income (loss) per Common Share	Securities that are entitled to participate in dividends with common stock, such as the Company’s Series A Conditional Convertible Preferred Stock (the “Preferred Stock”), are considered to be participating securities and the two-class method is used for purposes of calculating basic net income per share. Under the two-class method, a portion of net income is allocated to participating securities and excluded from the calculation of basic net income per common share. On December 21, 2012, all outstanding shares of Preferred Stock were converted into common stock; accordingly, for the two-class method calculation, the net income was allocated between common stock and Preferred Stock on a proportionate basis using a systematic and reasonable basis (based on number of days outstanding) for purpose of calculating the basic net income per share for the year ended December 31, 2012.
Discontinued Operations
	The results of operations of a disposal group held for sale or disposed is presented as discontinued operations when the underlying operations and cash flows of the disposal group will be, or have been, eliminated from the Company’s continuing operations and the Company no longer has the ability to influence the operating and/or financial policies of the disposal group. This assessment is made at the time the disposal group is classified as held for sale and for a one-year period after the sale of the disposal group.
Segment Information	The Company’s management relies on internal management reporting processes that provide revenue and operating income by reportable segment for making financial decisions and allocating resources. Segment operating income represents income before income taxes plus depreciation, amortization of intangible assets, share-based compensation expense, interest expense (net) and other, and unallocated corporate overhead. The Company’s management does not evaluate, manage or measure performance of segments using asset information; accordingly, asset information by segment is not prepared or disclosed.
Reclassifications	Certain reclassifications have been made to certain of the prior years’ consolidated financial statements to conform to the current year presentation. Specifically, 1) payments made into the Company’s life insurance policies to assist in funding the deferred compensation plan were reclassified from cash flows from operating activities to cash flows from investing activities; and 2) changes in book overdraft were reclassified from cash flows from financing activities to changes in accounts payable and accrued expenses within cash flows from operating activities in the consolidated statement of cash flows for both the year ended December 31, 2013 and 2012. In addition, the Company reclassified expected insurance recoveries under its professional liability and workers compensation policies in the consolidated balance sheet for the year ended December 31, 2013 to conform to the current year presentation. Professional liability and workers compensation liabilities were previously presented net of insurance recoveries. For the fiscal year ended December 31, 2014, expected insurance recoveries are presented on a gross basis, with the short-term insurance receivable portion included within “Prepaid and other current assets” and the long-term portion included within “Other assets” on the consolidated balance sheet.
