BASIS OF PRESENTATION	BASIS OF PRESENTATION The condensed consolidated balance sheets and related condensed consolidated statements of comprehensive income and cash flows contained in this Quarterly Report on Form 10-Q (this “Quarterly Report”), which are unaudited, include the accounts of AMN Healthcare Services, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all entries necessary for a fair presentation of such unaudited condensed consolidated financial statements have been included. These entries consisted of all normal recurring items. The results of operations for the interim period are not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year or for any future period. The unaudited condensed consolidated financial statements do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States. Please refer to the Company’s audited consolidated financial statements and the related notes for the fiscal year ended December 31, 2014, contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, filed with the Securities and Exchange Commission on February 25, 2015 (“2014 Annual Report”). The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 impairments, accruals for self-insurance, compensation and related benefits, accounts receivable, contingencies and litigation and income taxes. Actual results could differ from those estimates under different assumptions or conditions. Reclassification Certain reclassifications that are not material have been made to the prior year’s consolidated financial statements to conform to the current year presentation.

BUSINESS COMBINATIONS

Onward Healthcare Acquisition

On January 7, 2015, the Company completed its acquisition of Onward Healthcare, including its two wholly-owned subsidiaries, Locum Leaders and Medefis (collectively, “OH”), for approximately $76,945 in cash, funded by cash-on-hand and borrowings under the Company’s revolving credit facility. Onward Healthcare is a national nurse and allied healthcare staffing firm, Locum Leaders is a national locum tenens provider, and Medefis is a provider of a software as a service, or “SaaS,” based vendor management system for healthcare facilities. The acquisition helps the Company to expand its service lines and its supply and placement capabilities of healthcare professionals to its clients.

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. As of the filing date of this Form 10-Q, the Company is still finalizing the allocation of the purchase price, primarily related to tax matters and valuation of intangibles.

The preliminary allocation of the $76,945 purchase price consisted of $25,627 of fair value of tangible assets acquired (including $20,476 of accounts receivable), $21,603 of liabilities assumed (including $10,478 of accounts payable and accrued expenses), $30,219 of identified intangible assets, and $42,702 of goodwill, none of which is deductible for tax purposes. The intangible assets include the fair value of tradenames and trademarks, customer relationships, staffing database, acquired technologies and non-compete agreements. The weighted average useful life of the acquired intangible assets is approximately 11 years. The following table summarizes the fair value and useful life of each intangible asset acquired:



		Fair Value		Useful Life
				(in years)
Identifiable intangible assets
	Tradenames and Trademarks	$	8,100	3 - 15
	Customer Relationships	17,600		10 - 15
	Staffing Database	2,600		5
	Acquired Technologies	1,700		8
	Non-compete agreements	219		2
		$	30,219

Of the $42,702 allocated to goodwill, $37,233 and $5,469 were allocated to the Company’s nurse and allied healthcare staffing segment and locum tenens staffing segment, respectively.

The results of Onward Healthcare and Medefis are included in the Company’s nurse and allied healthcare staffing segment and the results of Locum Leaders are included in the Company’s locum tenens staffing segment. For the three months ended March 31, 2015, approximately $31,236 of revenue and $2,821 of income before income taxes of the Onward Healthcare entities were included in the unaudited condensed consolidated statement of operations since the date of acquisition.

The following summary presents unaudited pro forma consolidated results of operations of the Company for the three months ended March 31, 2015 and 2014 as if the OH acquisition described above had occurred on January 1, 2014. The following unaudited pro forma financial information gives effect to certain adjustments, including the reduction in compensation expense related to non-recurring executive salary expense, acquisition-related costs and the amortization of acquired intangible assets. The pro forma financial information is not necessarily indicative of the operating results that would have occurred had the acquisition been consummated as of the date indicated, nor are they necessarily indicative of future operating results.

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, for $17,520, which the Company funded through cash-on-hand and borrowings under its revolving credit facility. The total purchase price of $17,520 included $14,470 cash consideration paid, $1,650 cash holdback for potential claims, and contingent earn-out with a fair value of $1,400. During the three months ended March 31, 2015, the Company paid an additional $165 to the selling equityholders for a working capital adjustment. 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 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 acquisition agreement provides for a tiered contingent earn-out payment of up to $8,500 to be paid in 2016 based on the operating results of Avantas for the 12 month period ending June 30, 2016. As of the filing date of this Form 10-Q, the Company is still finalizing the allocation of the purchase price, primarily related to tax matters.

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, $9,960 of identified intangible assets and $9,916 of goodwill, which goodwill is deductible for tax purposes. 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.

The results of operations of Avantas are included in the nurse and allied healthcare staffing segment in the Company’s consolidated financial statements.

Revenue Recognition	3 Months Ended
Revenue Recognition	Mar. 31, 2015
Revenue Recognition [Abstract]
REVENUE RECOGNITION	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 records subcontractor accounts receivable from the client in the consolidated balance sheets. The Company generally pays the subcontractor after it has received payment from the client. Payables to subcontractors of $41,671 and $33,474, respectively, were included in accounts payable and accrued expenses in the unaudited condensed consolidated balance sheet as of March 31, 2015 and the audited consolidated balance sheet as of December 31, 2014.

Earnings Per Share [Abstract]

NET INCOME PER COMMON SHARE

Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted net income per common share reflects the effects of potentially dilutive share-based equity instruments.

Share-based awards to purchase 33 and 361 shares of common stock were not included in the calculation of diluted net income per common share for the three months ended March 31, 2015 and 2014, respectively, 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 three months ended March 31, 2015 and 2014, respectively:

Segment Reporting [Abstract]

SEGMENT INFORMATION

The Company has three reportable segments: nurse and allied healthcare staffing, locum tenens staffing and physician permanent placement services.

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 operating income by reportable segment to consolidated results and was derived from each segment’s internal financial information as used for corporate management purposes:

Fair Value Measurement

3 Months Ended

Mar. 31, 2015

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENTS

The Company’s valuation techniques and inputs used to measure fair value and the definition of the three levels (Level 1, Level 2 and Level 3) of the fair value hierarchy are disclosed in Part II, Item 8, “Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements - Note 4 - Fair Value Measurement” of the Company’s 2014 Annual Report. The Company has not changed the valuation techniques or inputs it uses to measure fair value during the three months ended March 31, 2015.

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 may have an obligation to pay earn-out consideration of up to $8,500 to the selling equity holders if Avantas meets certain future financial metrics for the 12 month period ending June 30, 2016. The earn-out liability was estimated based on estimated cash flows determined using the probability-weighted average of possible outcomes that would occur should certain financial metrics be reached. As there is no market data available to use in valuing the contingent consideration, the Company developed its own assumptions related to the future financial performance of Avantas to estimate the fair value of this liability. As such, the contingent consideration liability 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 for the 12 month period ending June 30, 2016. An increase or decrease in the probability of achievement will result in an increase or decrease to the estimated fair value of the contingent consideration. The Company reassesses the fair value each reporting period and adjusts the liability to its then fair value. There was no change in the fair value of the liability during the three months ended March 31, 2015.

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:



	Fair Value Measurements as of March 31, 2015
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
U.S. Treasury securities	$	5,291	$	5,291	$	—	$	—
Money market funds	335		335		—		—
Acquisition contingent consideration earn-out liability	1,400		—		—		1,400
Total financial assets and liabilities measured at fair value	$	7,026	$	5,626	$	—	$	1,400



	Fair Value Measurements as of December 31, 2014
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
U.S. Treasury securities	$	5,291	$	5,291	$	—	$	—
Money market funds	335		335		—		—
Acquisition contingent consideration earn-out liability	1,400		—		—		1,400
Total financial assets and liabilities measured at fair value	$	7,026	$	5,626	$	—	$	1,400

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 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 determines the fair value of its indefinite-lived intangible assets using the income approach (relief-from-royalty method) based on Level 3 inputs.

There were no triggering events identified and no indication of impairment of the Company’s goodwill, indefinite-lived intangible assets, long-lived assets or equity method investment during the three months ended March 31, 2015 and 2014.

Fair Value of Financial Instruments

The carrying amount of notes payable and revolving credit facility approximate their fair value as the instruments’ interest rates are variable and comparable to rates currently offered for similar debt instruments of comparable maturity. The fair value of the Company’s long-term self-insurance accruals cannot be estimated as the Company cannot reasonably determine the timing of future payments.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2015
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is subject to income taxation in the U.S. and various states and foreign jurisdictions. With few exceptions, as of March 31, 2015, the Company is no longer subject to U.S. federal, state, local or foreign income tax examinations by tax authorities for years before 2005. The Company’s tax years 2007, 2008, 2009 and 2010 have been under audit by the Internal Revenue Service (“IRS”) for several years and in 2014, the IRS issued the Company its Revenue Agent Report (“RAR”) and an Employment Tax Examination Report (“ETER”). The RAR proposed adjustments to the Company’s taxable income for 2007-2010 and net operating loss carryforwards from 2005-2006, resulting from the proposed disallowance of certain per diems paid to the Company’s healthcare professionals, and the ETER proposed assessments for additional payroll tax liabilities and penalties for 2009 and 2010 related to the Company’s treatment of certain non-taxable per diem allowances and travel benefits. The positions in the RAR and ETER are mutually exclusive, and contain multiple tax positions, some of which are contrary to each other. The Company filed a Protest Letter for both the RAR and ETER positions in 2014. The Company anticipates that the final settlement of the audits will occur in the next twelve months and believes its reserves are adequate to cover any final settlement. The IRS has also been conducting a separate audit of the Company’s 2011 and 2012 tax years. The income and employment tax issues addressed in the 2011 and 2012 examination are consistent with the issues raised in the 2007 through 2010 examination. During the quarter ended March 31, 2015, the IRS completed its 2011 and 2012 examination and issued its RAR and ETER to the Company. The proposed adjustments to the Company’s taxable income for 2011 and 2012 and net operating loss carryforwards from 2010, and the ETER proposed assessments for additional payroll tax liabilities and penalties for 2011 and 2012 related to the Company’s treatment of certain non-taxable per diem allowances and travel benefits. The positions in the RAR and ETER for the 2011 and 2012 years are mutually exclusive and 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 believes its reserves are adequate with respect to these open years. The Company was notified during the quarter ended March 31, 2015 that the IRS will also audit the Company’s 2013 tax year.

Commitments and Contingencies	3 Months Ended
Commitments and Contingencies	Mar. 31, 2015
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. Depending upon the particular facts and circumstances, the Company may also be subject to indemnification obligations under its contracts with such clients relating to these matters. The Company records a liability when management believes an adverse outcome from a loss contingency is both probable and the amount, or a range, can be reasonably estimated. Significant judgment is required to determine both probability of loss and the estimated amount. The Company reviews its loss contingencies at least quarterly and adjusts its accruals and/or disclosures to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, or other new information, as deemed necessary. With regards to outstanding loss contingencies as of March 31, 2015, the Company believes that such matters 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. (b) Leases 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 is ten years. The rent payments have been included in the total minimum lease payment table set forth in Part II, Item 8, “Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements - Note 12(b) - Commitments and Contingencies - Leases” of the Company’s 2014 Annual Report on Form 10-K.

This agreement expires on March 30, 2018, and no initial investment was made to enter into this agreement.

Basis of Presentation (Policies)	3 Months Ended
Basis of Presentation (Policies)	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 impairments, accruals for self-insurance, compensation and related benefits, accounts receivable, contingencies and litigation and income taxes. Actual results could differ from those estimates under different assumptions or conditions.
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 records subcontractor accounts receivable from the client in the consolidated balance sheets. The Company generally pays the subcontractor after it has received payment from the client.
Net Income per Common Share	Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted net income per common share reflects the effects of potentially dilutive share-based equity instruments.
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.
Fair Value of Financial Instruments	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. 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. Fair Value of Financial Instruments The carrying amount of notes payable and revolving credit facility approximate their fair value as the instruments’ interest rates are variable and comparable to rates currently offered for similar debt instruments of comparable maturity. The fair value of the Company’s long-term self-insurance accruals cannot be estimated as the Company cannot reasonably determine the timing of future payments.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
