The Business

Overview

NeoStem, Inc. (“we,” “NeoStem” or the “Company”) is a leader in the emerging cellular therapy industry. Cellular therapy addresses the process by which new cells are introduced into a tissue and administered to prevent or treat disease, or regenerate damaged or aged tissue. Modern cell-based therapies have progressed from the first recorded human to human blood transfusion 200 years ago through to the advanced cellular therapies of today including bone marrow and organ transplantation, tissue banking and reproductive in vitro fertilization and future therapies being investigated to treat cancer, cardiologic, neurologic, ophthalmic and orthopedic diseases among others. We anticipate that cellular therapies will have a large role in changing the natural history of the fight against chronic disease and in lessening the economic burden that these diseases pose to modern society.

Our business model includes the development of novel proprietary cell therapy products as well as operating a contract development and manufacturing organization (“CDMO”) providing services to others in the regenerative medicine industry. The combination of a therapeutic development business and revenue-generating service provider business provides the Company with unique capabilities for cost effective in-house product development and immediate revenue and cash flow generation.

Progenitor Cell Therapy, LLC, our wholly owned subsidiary (“PCT”), is a leading CDMO in the cellular therapy industry. Since its inception, PCT has provided pre-clinical and clinical current Good Manufacturing Practice (“cGMP”) development and manufacturing services to over 100 clients advancing regenerative medicine product candidates through rigorous quality standards all the way through to human testing. PCT's core competencies in the cellular therapy industry include manufacturing of cell therapy-based products, product and process development, cell and tissue processing, regulatory support, storage, distribution and delivery and consulting services. PCT has two cGMP, state-of-the art cell therapy research, development, and manufacturing facilities in New Jersey and California, serving the cell therapy community with integrated and regulatory compliant distribution capabilities. Expansion work currently in progress at PCT's New Jersey and California facilities is expected to be completed during the first quarter of 2014. The Company intends to pursue commercial expansion of our manufacturing operations both in the U.S. and internationally.

Our wholly-owned subsidiary, Amorcyte, LLC (“Amorcyte”), is developing AMR-001 for the treatment of cardiovascular disease. AMR-001 represents Amorcyte's most clinically advanced therapeutic product candidate and enrollment for the Phase 2 PreSERVE clinical trial to investigate AMR-001's safety and efficacy in preserving heart function after a particular type of acute myocardial infarction (“AMI”) commenced in 2012. We are on track to complete patient enrollment for this study in 2013 with the first data readout expected six to eight months after the last patient is infused. If approved by the U.S. Food and Drug Administration ("FDA") and/or other worldwide regulatory agencies, AMR-001 would address a significant unmet medical need in the treatment of AMI, potentially improving the quality and longevity of life for those afflicted, and positioning the Company to capture a meaningful share of the worldwide AMI therapy market. Potential congestive heart failure and traumatic brain injury indications for AMR-001 are also being explored.

Through our majority-owned subsidiary, Athelos Corporation (“Athelos”), we are collaborating with Becton-Dickinson and the University of California, San Francisco in early stage clinical development of a therapy that utilizes T-cells, to treat autoimmune and inflammatory conditions. We plan to file an Investigational New Drug Application ("IND") to investigate the clinical feasibility of nTreg-based therapeutics to prevent and/or treat steroid resistant asthma (preparing for Phase 1b/2a trial). Through INDs sponsored by UCSF we also plan to study nTreg-based therapeutics in prevention and/or treatment of type 1 diabetes (Phase 2 IND in preparation), and solid organ transplantation tolerance (Phase 1 IND submitted).

Pre-clinical assets include our VSEL^TM (Very Small Embryonic Like) Technology platform. We expect to file an IND with the FDA to initiate a National Institutes of Health ("NIH") funded human clinical study to investigate the impact of VSELs^TM in a tissue repair application. We are also working on a Department of Defense funded study of VSELs^TM for the treatment of chronic wounds. Other preclinical work with VSELs^TM includes exploring macular degeneration as a target indication.

NeoStem's origins are in adult stem cell collection and storage and we believe that as new therapeutics are developed utilizing one's own stored cells (autologous), the market penetration rate for the collection and storage business may rise sharply from its current low single digits percentage level, allowing our developing network to scale rapidly if the demand grows.

In 2011, we operated our business in three reportable segments: (i) Cell Therapy — United States; (ii) Regenerative Medicine — China; and (iii) Pharmaceutical Manufacturing — China. In 2012, we exited our operations in China. Effective March 31, 2012, we no longer operated in the Regenerative Medicine – China reportable segment, which was reported in discontinued operations in 2012 (see Note 14). On November 13, 2012, we completed the sale of our 51% interest in Suzhou Erye, which represented the operations in our Pharmaceutical Manufacturing - China segment, and is also reported in discontinued operations (see Note 14). As a result, we currently operate in a single reporting segment - Cell Therapy, which will focus on CDMO and cell therapy development programs.

We believe that NeoStem is ideally positioned to be an integrated leader in the cell therapy industry. We have significant basic research and development capabilities, manufacturing facilities on both the east and west coast of the United States, the support of regulatory and logistical expertise and a talented and experienced clinical team. We believe this expertise will allow us to achieve our mission of becoming the premier cell therapy company.

Basis of Presentation

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying Consolidated Financial Statements of the Company and its subsidiaries, which are unaudited, include all normal and recurring adjustments considered necessary to present fairly the Company’s financial position as of September 30, 2013 and the results of its operations and its cash flows for the periods presented. The unaudited consolidated financial statements herein should be read together with the historical consolidated financial statements of the Company for the years ended December 31, 2012 and 2011 included in our Annual Report on Form 10-K for the year ended December 31, 2012. Operating results for the nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of NeoStem, Inc. and its wholly owned and partially owned subsidiaries and affiliates as listed below, as well as the operations of our former Regenerative Medicine - China segment through the deconsolidation date on March 31, 2012 (see Note 14), and the operations of our former Pharmaceutical Manufacturing - China reporting segment through November 13, 2012, representing the date which the segment was sold (see Note 14). These former segments are reported in discontinued operations.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies [Text Block]

Summary of Significant Accounting Policies

In addition to the policies below, our significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2012. There were no changes during the nine months ended September 30, 2013.

Accounts Receivable

Accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts. The Company applies judgment in connection with establishing the allowance for doubtful accounts. Specifically, the Company analyzes the aging of accounts receivable balances, historical bad debts, customer concentration and credit-worthiness, current economic trends and changes in the Company’s customer payment terms. Significant changes in customer concentrations or payment terms, deterioration of customer credit-worthiness or weakening economic trends could have a significant impact on the collectability of the receivables and the Company’s operating results. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Management regularly reviews the aging of receivables and changes in payment trends by its customers, and records a reserve when it believes collection of amounts due are at risk.

Goodwill and Other Intangible Assets

Goodwill is the excess of purchase price over the fair value of identified net assets of businesses acquired. The Company’s intangible assets with an indefinite life are related to in process research and development for AMR-001, the clinical candidate acquired in the Amorcyte acquisition, as the Company expects this research and development to provide the Company with substantial benefit for a period that extends beyond the foreseeable horizon. Amortized intangible assets consist of customer lists, manufacturing technology, and tradename, as well as patents and rights associated primarily with the VSEL^TM Technology. These intangible assets are amortized on a straight line basis over their respective useful lives.

The Company reviews goodwill and indefinite-lived intangible assets at least annually for possible impairment. Goodwill and indefinite-lived intangible assets are reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company tests its goodwill and indefinite-lived intangible assets each year on December 31. The Company reviews the carrying value of goodwill and indefinite-lived intangible assets utilizing a discounted cash flow model, and, where appropriate, a market value approach is also utilized to supplement the discounted cash flow model. The Company makes assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values to determine each reporting unit’s estimated fair value. If these estimates or related assumptions change in the future, the Company may be required to record impairment charges.

Revenue Recognition

Clinical Services: The Company recognizes revenue for its (i) cell process development and (ii) cell manufacturing services based on the terms of individual contracts.

Revenues associated with cell process development services generally contain multiple stages that do not have stand-alone values and are dependent upon one another, and are recognized as revenue on a completed contract basis. We recognize revenues for cell development services when all of the following conditions are met:


•	persuasive evidence of an arrangement exists;


•	delivery has occurred or the services have been rendered;


•	the fee is fixed or determinable; and


•	collectability is probable.

The Company considers signed contracts as evidence of an arrangement. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the payment terms are subject to refund or adjustment. The Company assesses cash collectability based on a number of factors, including past collection history with the client and the client's creditworthiness. If the Company determines that collectability is not reasonably assured, it defers revenue recognition until collectability becomes reasonably assured, which is generally upon receipt of the cash.

Cell manufacturing services are generally distinct arrangements whereby the Company is paid for time and materials or for fixed monthly amounts. Revenue is recognized when efforts are expended or contractual terms have been met.

Some client agreements include multiple elements, comprised of cell process development and cell manufacturing services. The Company believes that cell process development and cell manufacturing services each have stand-alone value because these services can be provided separately by other companies. In accordance with ASC Update No. 2009-13, “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements,” the Company (1) separates deliverables into separate units of accounting when deliverables are sold in a bundled arrangement and (2) allocates the arrangement's consideration to each unit in the arrangement based on its relative selling price.

Clinical Services Reimbursements: The Company separately charges the customers for the expenses associated with certain consumable resources (reimbursable expenses) that are specified in each clinical services contract. On a monthly basis, the Company bills customers for reimbursable expenses and immediately recognizes these billings as revenue, as the revenue is deemed earned as reimbursable expenses are incurred. For the three months ended September 30, 2013 and 2012, clinical services reimbursements were $0.6 million and $0.9 million, respectively. For the nine months ended September 30, 2013 and 2012, clinical services reimbursements were $1.4 million and $2.9 million, respectively.

Processing and Storage Services: The Company recognizes revenue related to the collection and cryopreservation of cord blood and autologous adult stem cells when the cryopreservation process is completed which is approximately twenty-four hours after cells have been collected. Revenue related to advance payments of storage fees is recognized ratably over the period covered by the advance payments.

Cash and Cash Equivalents	9 Months Ended
Cash and Cash Equivalents	Sep. 30, 2013
Cash and Cash Equivalents [Abstract]
Cash and Cash Equivalents [Text Block]	Cash and Cash Equivalents As of September 30, 2013 and December 31, 2012, the Company had cash and cash equivalents of approximately $16.9 million and $13.7 million, respectively, including bank deposits of approximately $0.7 million and $0.8 million, respectively, covered by the Federal Deposit Insurance Corporation.

- Definition

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.

Fair Value Measurements [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

Fair value of financial assets and liabilities that are being measured and reported are defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market at the measurement date (exit price). The Company is required to classify fair value measurements in one of the following categories:

Level 1 inputs are defined as quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 inputs are defined as inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly or indirectly.

Level 3 inputs are defined as unobservable inputs for the assets or liabilities. Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.

The Company determined the fair value of the warrant derivative liabilities to be level 3 inputs. These inputs require material subjectivity because value is derived through the use of a lattice model that values the derivatives based on probability weighted discounted cash flows.

The Company also determined the fair value of contingent consideration, initially recognized on October 17, 2011 in connection with the Company's acquisition of Amorcyte, to be level 3 inputs. The fair value of contingent consideration obligations is based on a discounted cash flow model using a probability-weighted income approach. The measurement is based upon unobservable inputs supported by little or no market activity based on our own assumptions and experience. The value of our contingent consideration was initially calculated using a discount rate of 30%. We base the timing to complete the development and approval of this product on the current development stage of the product and the inherent difficulties and uncertainties in developing a product candidate, such as obtaining U.S. Food and Drug Administration (FDA) and other regulatory approvals. In determining the probability of regulatory approval and commercial success, we utilize data regarding similar milestone events from several sources, including industry studies and our own experience. These fair value measurements represent Level 3 measurements as they are based on significant inputs not observable in the market. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, changes in assumptions could have a material impact on the amount of contingent consideration expense we record in any given period. Changes in the fair value of the contingent consideration obligations are recorded in our consolidated statement of operations.

The following table sets forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013, and December 31, 2012 (in thousands):



	September 30, 2013
	Fair Value Measurements Using Fair Value Hierarchy
	Level 1		Level 2		Level 3
Warrant derivative liabilities	$	—	$	—	$	114.1
Contingent consideration	—		—		7,550.0

	Fair Value Measurements Using Fair Value Hierarchy
	Level 1		Level 2		Level 3
Warrant derivative liabilities	$	—	$	—	$	101.2
Contingent consideration	—		—		7,550.0

For those financial instruments with significant Level 3 inputs, the following table summarizes the activity for the three and nine months ended September 30, 2013 by type of instrument (in thousands):



	Three Months Ended				Nine Months Ended
	September 30, 2013				September 30, 2013
	Warrants		Contingent Consideration		Warrants		Contingent Consideration
Beginning liability balance	$	32.6	$	7,550.0	$	101.2	$	7,550.0
Change in fair value recorded in earnings	81.5		—		12.9		—
Ending liability balance	$	114.1	$	7,550.0	$	114.1	$	7,550.0

Some of the Company’s financial instruments are not measured at fair value on a recurring basis, but are recorded at amounts that approximate fair value due to their liquid or short-term nature, such as cash and cash equivalents, accounts receivable, accounts payable and notes payable, and long-term notes payable and mortgages.

- Definition

Debt [Abstract]
Debt Disclosure [Text Block]	Debt Notes Payable As of September 30, 2013 and December 31, 2012, the Company had notes payable of approximately $0.8 million and $0.4 million, respectively. The notes relate to certain insurance policies and equipment financings, require monthly payments, and mature within one to three years. Mortgages Payable On October 31, 2007, PCT issued a note to borrow $3.1 million (the “Note”) in connection with its $3.8 million purchase of condominium units in an existing building in Allendale, New Jersey (the “Property”) that PCT uses as a laboratory and stem cell processing facility. The Note is payable in 239 consecutive monthly payments of principal and interest, based on a 20 year amortization schedule; and one final payment of all outstanding principal plus accrued interest then due. The current monthly installment is $20,766, which includes interest at an initial rate of 5.00%; the interest rate and monthly installments payments are subject to adjustment on October 1, 2017. On that date, upon prior written notice, the lender has the option to declare the entire outstanding principal balance, together with all outstanding interest, due and payable in full. The Note is secured by substantially all of the assets of PCT, including a first mortgage on the Property and assignment of an amount approximately equal to eighteen months debt service held in escrow. The Note matures on October 1, 2027 if not called by the lender on October 1, 2017. The note is subject to certain debt service coverage and total debt to tangible net worth financial covenant ratios measured semi-annually. PCT was not in compliance with such covenants at the measurement date of December 31, 2012, and June 30, 2013, and obtained a covenant waiver letter from the lender for each period. The outstanding balance was approximately $2.5 million at September 30, 2013, and $2.6 million at December 31, 2012, respectively, of which $0.1 million is payable within twelve months as of September 30, 2013. The mortgage is classified as a current liability. On December 6, 2010 PCT Allendale, a wholly-owned subsidiary of PCT, entered into a note for a second mortgage in the amount of $1 million on the Allendale Property with TD Bank, N.A. This loan is guaranteed by PCT, DomaniCell (a wholly-owned subsidiary of PCT, now known as NeoStem Family Storage, LLC), Northern New Jersey Cancer Associates (“NNJCA”) and certain partners of NNJCA and is subject to an annual financial covenant starting December 31, 2011. PCT was not in compliance with such covenants at the measurement date of December 31, 2012, and obtained a covenant waiver letter from the lender. The loan is for 124 months at a fixed rate of 6% for the first 64 months. The loan is callable for a certain period prior to the interest reset date. The outstanding balance was approximately $0.8 million at September 30, 2013, and $0.8 million at December 31, 2012, respectively, of which $0.1 million is payable within twelve months as of September 30, 2013. The mortgage is classified as a current liability.

Shareholders’ Equity [Abstract]

Stockholders' Equity Note Disclosure [Text Block]

Shareholders' Equity

Reverse Stock Split

On June 28, 2013, pursuant to prior shareholder authorization, the Company’s board of directors unanimously approved a 1-for-10 reverse stock split of the Company’s common stock, which the Company effected on July 16, 2013. All share and per share amounts of common stock, options and warrants in the accompanying financial statements have been restated for all periods to give retroactive effect to the reverse stock split. The shares of common stock retained a par value of $0.001 per share. Accordingly, the stockholders’ deficit reflects the reverse stock split by reclassifying from “common stock” to “Additional paid-in capital” an amount equal to the par value of the decreased shares resulting from the reverse stock split.

Equity Issuances

In September 2011, the Company entered into a Common Stock Purchase Agreement, (the “Purchase Agreement”) with Aspire Capital Fund, LLC, an Illinois limited liability company (“Aspire Capital”), which provides that, subject to certain terms and conditions, Aspire Capital is committed to purchase up to an aggregate of $20.0 million worth of shares of the Company’s common stock over the term of the Purchase Agreement (initially 24 months). At the Company’s discretion, it may present Aspire Capital with purchase notices under the Purchase Agreement from time to time, to purchase the Company’s Common Stock, provided certain price and other requirements are met. The purchase price for the shares of stock is based upon one of two formulas set forth in the Purchase Agreement depending on the type of purchase notice we submit to Aspire Capital from time to time, and is based on market prices of the Company’s common stock (in the case of regular purchases) or a discount of 5% applied to volume weighted average prices (in the case of VWAP purchases), in each case as determined by parameters defined in the Purchase Agreement. The Company and Aspire Capital shall not effect any sales under the Purchase Agreement on any date where the closing sales price is less than 75% of the closing sales price on the business day immediately preceding the date of the Purchase Agreement. The Company’s net proceeds will depend on the purchase price and the frequency of the Company’s sales of shares to Aspire Capital; provided, however, that the maximum aggregate proceeds from sales of shares is $20.0 million. The Company’s delivery of purchase notices will be made subject to market conditions, in light of the Company’s capital needs from time to time and under the limitations contained in the Purchase Agreement. As consideration for entering into the Purchase Agreement, effective September 30, 2011, we issued 99,010 shares of our Common Stock to Aspire Capital (the “Commitment Shares”). The issuance of shares of common stock to Aspire Capital pursuant to the Purchase Agreement, including the Commitment Shares, and the sale of those shares from time to time by Aspire Capital to the public, are covered by an effective shelf registration statement on Form S-3.

In August 2012, the Company and Aspire entered into an amendment to the Purchase Agreement providing for an extension of the term of the Purchase Agreement until September 30, 2015. Pursuant to the amendment, we agreed to issue to Aspire a five-year warrant to purchase up to 161,290 shares of our common stock at an exercise price of $6.00 per share (the closing price of our common stock on the date the amendment was executed).

During the nine months ended September 30, 2013, the Company issued 1,639,659 shares of Common Stock under the provisions of its equity line of credit with Aspire for gross proceeds of approximately $11.1 million. As of September 30, 2013, the remaining amount available to the Company under the Purchase Agreement was $5.6 million.

In the second quarter of 2013, the Company completed an underwritten offering of 2.0 million shares of the Company's common stock, at a public offering price of $5.00 per share. The underwriters also exercised their entire over-allotment option of 0.3 million shares. The Company received gross proceeds of $11.5 million, before deducting underwriting discounts and commissions and offering expenses payable by the Company.

Option Exercises

During the nine months ended ended September 30, 2013, option holders exercised an aggregate of 16,369 options at exercise prices between $4.90 and $5.90 per share for gross proceeds of approximately $0.1 million.

Warrant Exercises

To raise capital on terms that we deemed favorable, during the nine months ended September 30, 2013, the Board authorized certain inducements to warrant holders to exercise outstanding common stock purchase warrants significantly before their expiration dates. The Company determined in each instance that such inducements were modifications of equity instruments, and an incremental fair value of the inducement was determined using the Black-Scholes option pricing model.

During the nine months ended ended September 30, 2013, warrant holders exercised an aggregate of 401,215 warrants at exercise prices between $5.10 and $7.40 per share for gross proceeds of approximately $2.1 million. As an inducement to exercise, we paid certain warrant holders $0.30 per share upon each exercise. The incremental fair value of the inducement recorded was $0.

Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes The Tax Reform Act of 1986 enacted a complex set of rules limiting the utilization of net operating loss carryforwards (“NOL”) to offset future taxable income following a corporate ownership change. The Company’s ability to utilize its NOL carryforwards is limited following a change in ownership in excess of fifty percentage points during any three-year period. Since the year 2000, the Company has had several changes in ownership which has resulted in a limitation on the Company’s ability to apply net operating losses to future taxable income. As of December 31, 2012, the Company has lost $26.0 million or $8.8 million in tax benefits, of net operating losses applicable to Federal income taxes which expired due to these limitations and expiration of net operating loss carryforwards. At December 31, 2012, the Company had net operating loss carryforwards of approximately $69.7 million applicable to future Federal income taxes. The tax loss carryforwards are subject to annual limitations and expire at various dates through 2030. The Company has recorded a full valuation allowance against its net deferred tax asset because it is more likely than not that such deferred tax assets will not be realized. Deferred tax liabilities were $4.1 million and $3.6 million as of September 30, 2013 and December 31, 2012, and relate to the taxable temporary differences on the goodwill recognized in the PCT acquisition in 2011, and the in-process R&D intangible asset recognized in the Amorcyte acquisition in 2011. The taxable temporary difference associated with the goodwill, which is tax deductible and will be amortized over 15 years, will continue to increase the deferred tax liability balance over the amortization period, with an associated charge to the tax provision in each period. The deferred tax liabilities will only reverse when these indefinite-lived assets are sold, impaired, or reclassified from an indefinite-lived asset to a finite-lived asset. As of September 30, 2013, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year.

Discontinued Operations

Regenerative Medicine - China segment

In 2009, the Company operated its Regenerative Medicine-China business in the People’s Republic of China (“China” or “PRC”) through its subsidiary, a wholly foreign owned entity (“WFOE”) and entered into contractual arrangements with certain variable interest entities (“VIEs”). Foreign companies have commonly used VIE structures to operate in the PRC, and while such structures are not uncommon, they had drawn greater scrutiny from the local Chinese business community in the PRC who urged the PRC State Council to clamp down on these structures. In addition, in December 2011, China’s Ministry of Health announced its intention to more tightly regulate stem cell clinical trials and stem cell therapeutic treatments in the PRC, which created uncertainty regarding the ultimate regulatory environment in the PRC. Accordingly, the Company took steps to restrict, and ultimately eliminate, its regenerative medicine business in the PRC. As a result of these steps, the Company discontinued its operations in its Regenerative Medicine-China business. The Company determined that any liability arising from the activities of the WFOE and the VIEs will likely be limited to the net assets currently held by each entity. As of March 31, 2012, the Company recognized the following loss on exit of the Regenerative Medicine-China business (in thousands):



Cash	$	195.1
Prepaid expenses and other current assets	14.9
Property, plant and equipment, net	1,023.7

Accumulated comprehensive income	(169.9		)
Loss on exit of segment	$	1,138.0

The operations and cash flows of the Regenerative Medicine - China business were eliminated from ongoing operations as a result of our exit decision, and the Company will not have continuing involvement in this business going forward. The operating results of the Regenerative Medicine – China business for the nine months ended September 30, 2012, which are included in discontinued operations, were as follows (in thousands):

Related Party Transactions [Abstract]
Related Party Transactions [Text Block]	Related Party Transactions On November 13, 2012, we and our subsidiary, CBH, sold our 51% ownership interest in Erye to Fullbright and EET (see Note 14). EET was prior to the sale the holder of the minority 49% ownership interest in Erye, and was a party along with our subsidiary CBH to the Joint Venture Agreement which had governed the ownership of the respective interests in Erye. Fullbright is an affiliate of EET. Mr. Shi Mingsheng (a former member of our Board of Directors, and Chairman of the Board of Erye) and Madam Zhang Jian (the General Manager of Erye, and formerly our Vice President of Pharmaceutical Operations) are the principal equity holders of each of EET and Fullbright. Fullbright assigned all its rights and obligations under the Equity Purchase Agreement (except for its obligations in respect of the return of certain NeoStem securities held by it as part of the purchase price, and its obligations in respect of closing deliverables) to Highacheive. As a result of the assignment, the Purchasers of our Erye Interest were EET and Highacheive.

Commitments and Contingencies

Lease Commitments

The Company leases offices, of which certain have escalation clauses and renewal options, and also leases equipment under certain noncancelable operating leases that expire from time to time through 2017.

A summary of future minimum rental payments required under operating leases that have initial or remaining terms in excess of one year as of September 30, 2013 are as follows (in thousands):



Years ended	Operating Leases
2013	$	223.1
2014	900.9
2015	726.7
2016	568.6
2017	294.7
Total minimum lease payments	$	2,714.0

Expense incurred under operating leases was approximately $0.3 million and $0.4 million for the three months ended September 30, 2013 and 2012, respectively, and $0.9 million and $1.2 million for the nine months ended September 30, 2013 and 2012, respectively.

Contingencies

Under license agreements with third parties the Company is typically required to pay maintenance fees, make milestone payments and/or pay other fees and expenses and pay royalties upon commercialization of products. The Company also sponsors research at various academic institutions, which research agreements generally provide us with an option to license new technology discovered during the course of the sponsored research.

In connection with the issuance to investors and service providers of many of the shares of the Company’s common stock and warrants to purchase common stock previously disclosed and described herein, the Company granted the holders registration rights providing for the registration of such shares of common stock and shares of common stock underlying warrants on a registration statement to be filed with the Securities and Exchange Commission (“SEC”) so as to permit the resale of those shares. Certain of the registration rights agreements provided for penalties for failure to file or failure to obtain an effective registration statement. With respect to satisfying its obligations to the holders of these registration rights, the Company has been in various situations. The Company had previously filed a registration statement as required for some of the holders, and in May 2011 filed a registration statement for all of the holders (except for holders whose shares of Common Stock were currently salable under Rule 144 of the Securities Act or who waived certain rights); such registration statement was declared effective by the SEC on September 30, 2011. The Company has certain obligations to maintain the effectiveness of this registration statement. Certain holders who had outstanding registration rights had previously waived their registration rights or were subject to lock-up agreements. No holder has yet asserted any claim against the Company with respect to a failure to satisfy any registration obligations. Were someone to assert a claim against the Company for breach of registration obligations, the Company believes it has several defenses that would result in relieving it from some or any liability, although no assurances can be given. The Company also notes that damage claims may be limited, as (i) most shares of Common Stock as to which registration rights attached are either now registered or currently salable under Rule 144 of the Securities Act or are otherwise currently subject to other restrictions on sale and (ii) the shares of Common Stock underlying warrants with registration rights are now registered, and during much of the relevant periods the warrants with registration rights generally have been out of the money, were subject to lock-up agreements and/or the underlying shares of Common Stock were otherwise subject to restrictions on resale. Accordingly, were holders to assert claims against the Company based on breach of the Company’s obligation to register, the Company believes that the Company’s maximum exposure would not be material.

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.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

- Definition

For the disposal group, including a component of the entity (discontinued operation), cash includes currency on hand as well as demand deposits with banks or financial institutions. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months.
