Explanatory Note

We are filing this Amendment No. 1 to our Quarterly Report on Form 10-Q for the period ended June 30, 2013 to amend and restate portions of our original Quarterly Report for this period (the “Original Report”). This Amendment No. 1 amends and restates the following items from the Original Report: (A) Part I, Item I — Financial Statements, (B) Part I, Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations, (C) Part I, Item 4 — Controls and Procedures, and (D) Part II, Item IA – Risk Factors.

The disclosures set forth in these items in the Original Report, that are amended by this Amendment No. 1 include:

• Amendments to Part I, Item I — Financial Statements, to restate our financial results for the three and six months ended June 30, 2013 and 2012 to reflect: (i) $2.1 million and $4.2 million of intangible asset amortization in the three and six months ended June 30, 2013, respectively; (ii) a reduction in operating expenses related to certain accounts payable and other accrued obligations accounts which had the effect of overstating our consolidated operating expenses by $0.1 million and $0.5 million for the three months ended June 30, 2013 and 2012, respectively, and by $0.5 million and $1.0 million for the six months ended June 30, 2013 and 2012, respectively; (iii) the impact on our intangible assets, goodwill, and income tax accounts for the effects of items (i) and/or (ii) within our balance sheet as of December 31, 2012 and June 30, 2013; and (iv) resulting reclassifications within our statements of cash flows for the six months ended June 30, 2013 and 2012 for (i), (ii), and (iii).

• Amendments to Part I, Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations, to reflect the above-described restatement of our financial results.

• Amendments to Part I, Item 4 — Controls and Procedures, to describe changes in our disclosure controls and procedures and our internal controls over financial reporting to address a material weakness.

• Amendments to Part II, Item 1A — Risk Factors, to add an additional risk factor regarding our internal controls over financial reporting as a result of the identification of a material weakness in our financial reporting.

The restatement results from errors related to our accounting for the acquisition of Allos Therapeutics, Inc. in September 2012. We designated an acquired intangible asset as in-process research & development (IPR&D), which should have instead been designated at the acquisition date as a definite-lived intangible asset, as described above within (i).

Also, during the financial statement close process for the quarter ended September 30, 2013, management identified an accounting issue related to an over-accrual of accounts payable and accrued obligations that accumulated between January 1, 2007 through June 30, 2013, as described above within (ii).

The combined impact of the adjustments to the applicable line items in our consolidated financial statements for the periods subject to restatement (collectively, the “Restated Periods”) is set forth in Note 1A, “Restatement of Condensed Consolidated Financial Statements,” included in Part I, Item 1, of this Form 10-Q. Management has also concluded that, as of June 30, 2013, our internal controls over financial reporting were not effective due to a material weakness in our controls over our accounting for, and reporting of, the over-accrual of accounts payable and accrued obligations.

We believe that presenting the restated information regarding the Restated Periods in this Form 10-Q allows investors to review all pertinent data in a single presentation. In addition, the Company’s periodic reports to be filed during fiscal 2013 will include the restated 2012 comparable prior period and year-to-date periods. Accordingly, investors should rely only on the financial information and other disclosures regarding the Restated Periods in this Form 10-Q or in future filings with the Securities and Exchange Commission, as applicable, and not on any previously issued or filed reports, earnings releases or similar communications relating to these periods. The restatement has no effect on our net cash used in operating activities or on our cash and cash equivalents or short-term investments for the Restated Periods.

1. Business and Basis of Presentation

Business

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biotechnology company with fully integrated commercial and drug development operations, with a primary focus in oncology and hematology. Our strategy is comprised of acquiring, developing and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. We currently market three oncology drugs—FUSILEV^® (levoleucovorin) for injection in the U.S., ZEVALIN^® (ibritumomab tiuxetan) injection for intravenous use, for which we have worldwide rights and FOLOTYN^® a folate analogue metabolic inhibitor designed to accumulate preferentially in cancer cells. We also have a diversified pipeline of product candidates in advanced-stage Phase 2 and Phase 3 studies. We have assembled an integrated in-house scientific team, including formulation development, clinical development, medical research, regulatory affairs, biostatistics and data management, and have established a commercial infrastructure for the marketing of our drug products. We also leverage the expertise of our worldwide partners to assist in the execution of our strategy.

Basis of Presentation

We have prepared the accompanying unaudited condensed consolidated financial statements, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. We have condensed or omitted certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) pursuant to such rules and regulations. On April 1, 2012, Spectrum acquired the licensing rights to market ZEVALIN (the “ZEVALIN Rights”) outside of the U.S. On September 5, 2012, Spectrum acquired Allos Therapeutics, Inc. (“Allos”). Commencing April 1, 2012 and September 5, 2012, respectively, our financial statements include the assets, liabilities, operating results and cash flows of the ZEVALIN Rights and Allos.

The condensed consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The unaudited condensed consolidated financial statements reflect all adjustments, which are normal and recurring, that are, in the opinion of management, necessary to fairly state the financial position as of June 30, 2013 and the results of operations and cash flows for the related interim periods ended June 30, 2013 and 2012. The results of operations and trends for the six months ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any other periods. The unaudited financial statements included in this quarterly report should be read in conjunction with our audited financial statements for the year ended December 31, 2012, included in the Annual Report on Form 10-K filed with the SEC.

Significant Accounting Policies

The accounting policies followed by us and other information are contained in the notes to the Company’s audited consolidated financial statements for the year ended December 31, 2012 included in our Annual Report on Form 10-K filed on February 28, 2013 with the SEC. We have not changed our significant accounting policies as of June 30, 2013. You should read this Quarterly Report on Form 10-Q in connection with the information contained in our Annual Report on Form 10-K filed on February 28, 2013.

Variable Interest Entity

Our Canadian affiliate, Spectrum Pharma Canada, is owned 50% by us and was organized in Quebec, Canada in January 2008. We fund 100% of the expenditures and, as a result, we are the party with the controlling financial interest. We are the primary beneficiary of Spectrum Pharma Canada, which is determined to be a variable interest entity. As a result of this characterization, it is consolidated in our financial statements as though it is a wholly-owned subsidiary. We have eliminated all significant intercompany balances and transactions among the consolidated entities from the condensed consolidated financial statements.

Segment and Geographic Information

We operate in one reportable segment: acquiring, developing and commercializing prescription drug products. We evaluate all revenues by product in the aggregate given the similarity of product, production processes, customers, distribution methods and regulatory environment. Accordingly, we report the accompanying condensed consolidated financial statements in the aggregate, including all of our activities in one reportable segment.

7

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent obligations in the financial statements and accompanying notes. The estimation process requires assumptions to be made about future events and conditions, and as such, is inherently subjective and uncertain. Actual results could differ materially from our estimates.

On an ongoing basis, we evaluate our estimates, including those related to deferred revenue recognition periods, inventories, the impairment of investments, the impairment of goodwill and long-lived assets, contingencies, accrued clinical trial expenses, stock-based compensation, and ongoing litigation, among other estimates. We base our estimates on historical experience and on other assumptions that management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

Revenue Recognition

Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer. We sell our products to wholesalers and distributors of oncology products and directly to the end user, directly or through Group Purchasing Organizations or GPO’s (e.g., certain hospitals or hospital systems and clinics with whom we have entered into a direct purchase agreement). Our wholesalers and distributors purchase our products and sell the products directly to end users, which include, but are not limited to, hospitals, clinics, medical facilities, managed care facilities and private oncology based practices. Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer, and the following additional criteria are met:

(i) the price is substantially fixed and determinable;

(ii) our customer has economic substance apart from that provided by us;

(iii) our customer’s obligation to pay us is not contingent on resale of the product;

(iv) we do not have significant obligations for future performance to directly bring about the resale of our product; and

(v) we have a reasonable basis to estimate future returns.

Generally revenue is recognized when all four of the following criteria are met:

(i) persuasive evidence that an arrangement exists;

(ii) delivery of the products has occurred, or services have been rendered;

(iii) the selling price is both fixed and determinable; and

(iv) collectability is reasonably assured.

We calculate a provision for estimated product returns, sales discounts, rebates, chargebacks and distribution and data fees are established as a reduction of gross product sales at the time such revenues are recognized. Thus, revenue is recorded, net of such estimated provisions. We state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

We utilize a third-party logistics company to store and distribute FUSILEV. The same third party logistics company also stores and ships in the U.S. ZEVALIN kits containing the CD20 MAB.

During 2009, we changed the supply and distribution model for ZEVALIN in the U.S. Previously, we sold ZEVALIN kits containing the CD20 MAB to radiopharmacies, who in turn ordered the radioactive isotope (Y-90 or In-111) separately and radiolabeled (or attached) the radioactive isotope to the CD20 MAB. The radiopharmacy then sold the end user product to the consumer. Under the current model in the U.S. we do not sell the ZEVALIN kits containing the CD20 MAB to the radiopharmacies, but instead contract with them, as a fee-for-service, to radiolabel the individual components of the CD20 MAB to the radioactive isotope, and then, also under a fee-for-service arrangement, have them distribute the end use product to the end user; the clinics, hospitals or other medical settings. In this regard, we now sell the CD20 MAB together with the radioactive isotope in the U.S. as the end user product. In November 2011, we received FDA approval to remove the bioscan and starting in January 2012 we are no longer supplying the imaging kit (In-111) in the U.S. which was formerly used for the bioscan.

8

Beginning in the second quarter of 2013, we terminated our transition services agreement with Bayer Pharma AG and transitioned to a sales distribution model in Europe. Sales of ZEVALIN to certain new customers will be recognized on a cash basis until collectability is reasonably assured.

Product Returns Allowances

Customers are typically permitted to return products within thirty days after shipment, if incorrectly shipped or not ordered, and six months after the expiration of product dating for FUSILEV, subject to certain restocking fees and preauthorization requirements, as applicable. The returned product is destroyed if it is damaged, quality is compromised or past its expiration date. In general, returned product is not resold. As of each balance sheet date, we estimate potential returns, based on several factors, including: inventory held by distributors, sell through data of distributor sales to end users, customer and end-user ordering and re-ordering patterns, aging of accounts receivables, rates of returns for directly substitutable products and pharmaceutical products for the treatment of therapeutic areas similar to indications served by our products, shelf life of our products, historical rates of actual returns and based on experience of our management with selling similar oncology products. We record an allowance for future returns by reducing product sales and crediting a reserve for returns to increase other accrued obligations at the time of the product sales. No returns reserve is recorded for ZEVALIN since in the U.S. we invoice our end user customers and recognize revenues only when a patient is treated with ZEVALIN and for Ex. U.S. we invoice upon delivery. FOLOTYN returns are limited to defective product or product that was shipped in error.

Government Chargebacks

Our products are subject to certain programs with federal government qualified entities whereby pricing on products is discounted below distributor list price to participating entities. These entities purchase products through distributors at the discounted price, and the distributors charge the difference between their acquisition cost and the discounted price back to us. We account for chargebacks by reducing revenue and establishing an accrual in an amount equal to our estimate of chargeback claims at the time of product sale. We also evaluate the adequacy of previously recorded chargebacks based on data regarding specific entities claims activity over time to adjust current period chargebacks for these same distributors. Due to estimates and assumptions inherent in determining the amount of government chargebacks, the time lag to receive information from distributors, the actual amount of claims for chargebacks may be materially different from our estimates, at which time we would adjust our reserves accordingly.

Discounts

Discounts (generally prompt payment discounts) are accrued at the end of every reporting period based on the gross sales made to customers during the period and based on their terms of trade for a product. We generally review the terms of the contracts, specifically price and discount structures, and payment terms between the customer and us to estimate the discount accrual.

Rebates

Customer rebates are estimated at every period end, based on direct purchases, depending on whether any rebates have been offered based on definitive contractual agreements. The rebates are recognized when products are purchased and a periodic credit is given.

Medicaid Rebates

Our products are subject to state government-managed Medicaid programs whereby discounts and rebates are provided to participating state governments. We record estimated rebates payable under governmental programs, including Medicaid, as a reduction of revenue in the same period the related sale is recorded. Our calculations related to these rebate accruals require estimates, including estimates of customer mix primarily based on a combination of market and clinical research, to determine which sales will be subject to rebates and the amount of such rebates. Our estimate of utilization is based on historical claims and supplemented by management’s judgment with respect to many factors, including changes in sales trends, an evaluation of current laws and regulations and product pricing. We update our estimates and assumptions each period and record any necessary adjustments to our reserves. Commencing in the second quarter of 2013, we refined our methodology to estimate rebate claims remaining in channel inventory which resulted in a $1.0 million increase in the Medicaid rebate accrual at June 30, 2013 and corresponding increase to net loss for the three and six months ended June 30, 2013. Additionally, there is a time lag between the date we determine the estimated liability and when we actually pay the liability. Although allowances and accruals are recorded at the time of product sale, certain rebates are typically paid out, on average, up to six months or longer after the sale.

Distribution and Data Fees

Distribution and data fees are paid to authorized wholesalers and specialty distributors of FUSILEV and FOLOTYN as a percentage of WAC for products sold which is a reduction of revenue in the same period the related sale is recorded. The services provided include contract administration, inventory management, product sales reporting by customer and returns for clinics and hospitals. We accrue distribution and data fees based on a percentage of FUSILEV and FOLOTYN revenues that are set and governed by distribution agreements.

Accounts Receivable

We also state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

Milestone Payments

Milestone payments under collaborative arrangements are triggered either by the results of our research and development efforts or by specified sales results by a third-party collaborator. Milestones related to our development-based activities may include initiation of various phases of clinical trials, successful completion of a phase of development or results from a clinical trial, acceptance of a New Drug Application by the FDA or an equivalent filing with an equivalent regulatory agency in another territory, or regulatory approval by the FDA or by an equivalent regulatory agency in another territory. Due to the uncertainty involved in meeting these development-based milestones, the development-based milestones are considered to be substantial (i.e. not just achieved through passage of time) at the inception of the collaboration agreement. In addition, the amounts of the payments assigned thereto are considered to be commensurate with the enhancement of the value of the delivered intellectual property as a result of our performance. Our involvement is necessary to the achievement of development-based milestones. We would account for development-based milestones as revenue upon achievement of the substantive milestone events. Milestones related to sales-based activities may be triggered upon events such as the first commercial sale of a product or when sales first achieve a defined level. These sales-based milestones would be achieved after the completion of our development activities. We would account for the sales-based milestones in the same manner as royalties, with revenue recognized upon achievement of the milestone. In addition, upon the achievement of either development-based or sales-based milestone events, we have no future performance obligations related to any milestone payments.

License Fees

We recognize license fees based on the facts and circumstances of each contractual agreement. In general, we recognize income upon the signing of a contractual agreement that grants rights to products or technology to a third party if we have no further obligation to provide products or services to the third party after entering into the contract.

Research and Development

Research and development expenses include salaries and benefits, clinical trial and related manufacturing costs, contract and other outside service fees, and facilities and overhead costs related to our research and development efforts. Research and development expenses also consist of costs incurred for proprietary and collaborative research and development and include activities such as product registries and investigator-sponsored trials. Research and development costs are expensed as incurred. In certain instances, we enter into agreements with third parties for research and development activities, where we may prepay fees for services at the initiation of the contract. We record such prepayment as a prepaid asset and charge research and development expense over the period of time the contracted research and development services are performed. Other types of arrangements with third parties may be fixed fee or fee for service, and may include monthly payments or payments upon the completion of milestones or receipt of deliverables.

As of each balance sheet date, we review purchase commitments and accrue drug development expenses based on factors such as estimates of work performed, patient enrollment, completion of patient studies and other events. We maintain regular communication with our vendors, including our clinical sites, and gauge the reasonableness of estimates provided. However, actual clinical trial costs may differ materially from estimated clinical trial costs and are adjusted for in the period in which they become known.

Goodwill and Intangible Assets

Goodwill represents the excess of acquisition cost over the fair value of the net assets of the acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead tested for impairment annually unless there are interim impairment indicators. We perform our annual evaluation as of October 1 each year.

Intangible assets are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable. Our policy is to identify and record impairment losses, if necessary, on intangible product rights when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. It is our policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

We acquired 50% of the rights in RIT in December 2008 and the remaining 50% in March 2009. The purchase price for the acquisition of ZEVALIN rights was allocated to identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date which is being amortized over its useful life of 10 years. Such a valuation requires significant estimates and assumptions including but not limited to: determining the timing and expected costs to complete the in-process projects, projecting regulatory approvals, estimating future cash flows from product sales resulting from in-process projects, and developing appropriate discount rates and probability rates by project. We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions.

Identifiable intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives, ranging from 1 to 10 years.

We acquired all of the oncology drug assets of Targent in April 2006. As part of the consideration for the purchase of these assets, we agreed to pay milestone payments to Targent upon the achievement of certain regulatory events as well as for certain sales levels for FUSILEV within a calendar year. During 2011, we capitalized $16.8 million associated with the achievement of these milestones which are being amortized to cost of product sales sold on a straight-line basis over the estimated useful life of 8.7 years.

On April 1, 2012, we acquired the licensing rights to market ZEVALIN outside of the U.S. (ZEVALIN Rights) from Bayer Pharma AG or Bayer. The process for estimating the fair values of these identifiable intangible assets involved the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. These identified intangible assets are being amortized over the estimated useful life of 10 years.

We acquired Allos on September 5, 2012, and recorded intangible assets related to developed technology and distribution rights. The developed technology and distribution rights are amortized over the expected patent life of 10-15 years. The fair value of these intangible assets was estimated using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value considered our estimates of future incremental earnings that may be achieved by the intangible assets.

With respect to the acquisition we believe the fair values assigned to the assets acquired and liabilities assumed were based upon reasonable assumptions. Our allocation of the purchase price was largely dependent on discounted cash flow analyses of projects and products of Allos. We cannot provide assurance that the underlying assumptions used to forecast the cash flows or the timely and successful completion of such projects will materialize as we estimated. For these reasons, among others, our actual results may vary significantly from the estimated results.

On March 8, 2013, we acquired the global development and commercialization rights to Captisol-enabled^®, propylene glycol-free (PG-free) melphalan and capitalized $7.7 million associated with the in process research and development.

On May 29, 2013, we amended our agreement with Mundipharma (see Notes 6 and 10).

We evaluate the recoverability of indefinite and definite intangible assets whenever events or changes in circumstances indicate that an intangible asset’s carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

(i) a significant decrease in the market value of an asset;

(ii) a significant adverse change in the extent or manner in which an asset is used; or

(iii) an accumulation of costs significantly in excess of the amount originally expected for the acquisition of an asset.

11

We measure the carrying amount of the asset against the estimated undiscounted future cash flows associated with it. Should the sum of the expected future net cash flows be less than the carrying value of the asset being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds its fair value. We recorded an impairment loss of $1.0 million during the three and six months ended June 30, 2013 related to the amendment of the Mundipharma agreement in May 2013. There were no other impairment losses recorded during the quarters ended June 30, 2013 or 2012.

Acquisitions and Collaborations

For all in-licensed products, we perform an analysis to determine whether we hold a variable interest or interests that give us a controlling financial interest in a variable interest entity. On the basis of our interpretations and conclusions, we determine whether the acquisition falls under the purview of variable interest entity accounting and if so, consider the necessity to consolidate the acquisition. As of June 30, 2013, we determined there were no variable interest entities required to be consolidated other than our Canadian affiliate, Spectrum Pharma Canada.

We also perform an analysis to determine if the inputs and/or processes acquired in an acquisition qualify as a business. On the basis of our interpretations and conclusions, we determine if the in-licensed products qualify as a business and whether to account for such products as a business combination or an asset acquisition. The accounting for acquisitions requires extensive use of estimates and judgments to measure the fair value of the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed. Additionally, we must determine whether an acquired entity is considered to be a business or a set of net assets, because the excess of the purchase price over the fair value of net assets acquired can only be recognized as goodwill in a business combination. The excess of the purchase price over the fair value of the net assets acquired can only be recognized as goodwill in a business combination.

Foreign Currency Translation

We translate the assets and liabilities of our foreign subsidiaries stated in local functional currencies to US dollars at the rates of exchange in effect at the end of the period. Revenues and expenses are translated using rates of exchange in effect during the period. Gains and losses from the translation of financial statements denominated in foreign currencies are included as a separate component of accumulated other comprehensive income (loss) in the statement of comprehensive income (loss).

We record foreign currency transactions at the exchange rate prevailing at the date of the transaction with resultant gains and losses being included in results of operations. Foreign currency transaction gains and losses have not been significant for any period presented.

Comprehensive Income (Loss)

Comprehensive income (loss) is calculated in accordance with authoritative guidance which requires the disclosure of all components of comprehensive income, including net income (loss) and changes in equity during a period from transactions and other events and circumstances generated from non-owner sources. Our accumulated other comprehensive income (loss) at June 30, 2013 and 2012, respectively consisted primarily of foreign currency translation adjustments and net unrealized gains/losses on investments in marketable securities as of that date.

Recently Adopted Accounting Standards

In February 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update that requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amounts are required to be reclassified in their entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance became effective for reporting periods beginning after December 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013 and had no significant reclassifications out of accumulated other comprehensive income to net loss during the six months ended June 30, 2013.

In July 2012, the FASB issued an accounting standards update that gives an entity the option to first assess qualitative factors 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, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. This guidance became effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013. The adoption did not have a material impact on our consolidated financial statements.

12

New Accounting Standards Not Yet Adopted

In March 2013, the FASB issued an accounting standards update that provides guidance on the accounting for the cumulative translation adjustment (the “CTA”) upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this guidance, an entity should recognize the CTA in earnings based on meeting certain criteria, including when it ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity or upon a sale or transfer that results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets resides. This guidance will be effective for fiscal years beginning on or after December 15, 2013, which will be our fiscal year 2014, with early adoption permitted. We currently do not expect the adoption of the guidance will have a material impact on our consolidated financial statements.

Basic and Diluted Earnings (Loss) per Share

We calculate basic and diluted net income (loss) per share using the weighted average number of common shares outstanding during the periods presented, and adjust the amount of net income (loss) used in this calculation for preferred stock dividends (if any) declared during the period. In periods of a net loss position, basic and diluted loss per share are the same. For the diluted earnings per share calculation, we adjust the weighted average number of common shares outstanding to include dilutive stock options, warrants and other common stock equivalents outstanding during the period.

1A. Restatement of Condensed Consolidated Financial Statements

Overview

The Company has restated its previously issued condensed consolidated financial statements for the three and six months ended June 30, 2013 and 2012, and balance sheet as of December 31, 2012, to correct certain errors as described below:

(i) Our accounting for the intangible asset acquired as part of our September 2012 acquisition of Allos Therapeutics, Inc. This intangible asset was recognized as in-process research & development (IPR&D), but should have instead been recognized as a definite-lived intangible asset. The error resulted in an understatement of amortization of approximately $2.1 million per quarter for this intangible asset.

(ii) An over-accrual of research and development and sales and marketing expenses that accumulated from January 1, 2007 through June 30, 2013. The aggregate impact over this entire period was approximately $7.7 million. As a result, $0.1 million and $0.5 million in the three months ended June 30, 2013 and 2012, respectively, and $0.5 million and $1.0 million in the six months ended June 30, 2013 and 2012, respectively, of excess operating expenses were recognized. The overstatement is comprised of (i) $6.7 million in excess accruals that correspond with our research and development and sales and marketing activities, and (ii) $1.0 million in excess liabilities that were recorded as part of our business combination accounting for the 2009 acquisition of RIT Oncology, LLC. As with the $6.7 million in excess accruals, this $1.0 million does not require settlement, and was not identified as such within a timely manner.

Financial Statement Presentation – Current and Future Periods

Our accompanying December 31, 2012 Condensed Consolidated Balance Sheet reflects the correction of the cumulative error of $7.2 million that existed through that date, as an adjustment to “accumulated deficit,” and the correction of the corresponding financial statement accounts including “deferred tax assets”, “accounts payable and other accrued obligations” and “accrued drug development costs”. The comparative results for the three and six months ended June 30, 2012, within the accompanying Condensed Consolidated Statements of Operations, reflect (a) increases in “amortization and impairment of purchased intangible assets”, (b) increases/reductions in “benefit for income taxes”, and (c) reductions of “selling general and administrative” and “research and development” expenses for the errors that correspond to these periods.

The accompanying restated Condensed Consolidated Financial Information in this Quarterly Report on Form 10-Q as of June 30, 2013 and December 31, 2012, and for the three and six months ended June 30, 2013 and 2012, has been labeled as “As Restated.”

2. Acquisitions

Acquisition of Rights to Captisol-Enabled^® Melphalan

On March 8, 2013, we completed the acquisition of exclusive global development and commercialization rights to Captisol-enabled^®, propylene glycol-free melphalan from CyDex Pharmaceuticals, Inc. a wholly-owned subsidiary of Ligand Pharmaceuticals Incorporated (“Ligand”). The Captisol-enabled melphalan product candidate is currently in a pivotal trial being conducted by Ligand for use as a conditioning treatment prior to autologous stem cell transplant for patients with multiple myeloma. Pursuant to the license agreement, Spectrum assumed the responsibility for the ongoing clinical and regulatory development of the program going forward. Under the agreement, Ligand received a license fee of $3.0 million on April 1, 2013 and is eligible to receive milestone payments upon achievement of certain regulatory and net sales thresholds, as well as royalties upon successful commercialization based on a percentage of net sales of the licensed products in all territories.

We accounted for the acquisition of the rights as a business combination using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the purchase date and be recorded on the balance sheet regardless of the likelihood of success of the related product or technology. The process for estimating the fair values of identifiable intangible assets involves the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. Transaction costs are not included as a component of consideration transferred and were expensed as incurred. The related transaction costs expensed for the three months ended March 31, 2013 were approximately $15,000. There were no corresponding expenses for the three months ended June 30, 2013.

Consideration Transferred

The acquisition-date fair value of the consideration transferred consisted of the following items ($ in 000’s):

Cash consideration	$	3,000
Liability assumed—contingent consideration		4,700
Total purchase consideration	$	7,700

Fair Value Estimate of Asset Acquired and Liability Assumed

The total purchase consideration is allocated to the acquisition of the net tangible and intangible assets based on their estimated fair values as of the closing date. The allocation of the total purchase price to the net assets acquired is as follows ($ in 000’s):

In-process research and development—Captisol-enabled^®, propylene glycol-free melphalan rights $ 7,700

Acquired in-process research and development (“IPR&D) is an intangible asset classified as an indefinite-lived asset until the completion or abandonment of the associated R&D effort, and will be amortized over an estimated useful life to be determined at the date the project is completed. Intangible IPR&D is not amortized during the period that it is considered indefinite-lived but rather tested for impairment.

19

We estimated the fair value of the in-process research and development using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value estimate took into account our estimates of future incremental earnings that may be achieved upon regulatory approval, promotion and distribution associated with the rights, and included estimated cash flows of approximately 10 years and a discount rate of approximately 25%.

The fair value of the contingent consideration liability assumed was determined using the probability of success and the discounted cash flow method of the income approach assuming the U.S. Food and Drug Administration, or FDA, approval of Captisol-enabled^® melphalan is will occur on or about December 31, 2015. Upon receipt of regulatory approval, Spectrum will be obligated to make a milestone payment to Ligand.

We do not consider the acquisition of the global development and commercialization rights to Captisol-enabled^®, propylene glycol-free melphalan to be a material business combination and, therefore, have not disclosed the pro forma results of operations as required for material business combinations.

Allos Acquisition

Spectrum acquired Allos Therapeutics, Inc. on September 5, 2012 as discussed further in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 filed on February 27, 2013. The results of operations of the Allos acquisition are included in the accompanying condensed consolidated statements of operations for the three and six months ended June 30, 2012. The pro forma results of operations are prepared for comparative purposes only and do not necessarily reflect the results that would have occurred had the acquisition occurred at the beginning of the years presented or the results which may occur in the future. The following unaudited pro forma results of operations for the three and six months ended June 30, 2012 assume the Allos acquisition had occurred on January 1, 2012 ($ in 000’s):

	Three Months Ended June 30, 2012 (As Restated)		Six Months Ended June 30, 2012 (As Restated)

3. Cash, Equivalents and Marketable Securities

As of June 30, 2013, we held substantially all of our cash, equivalents and marketable securities at major financial institutions, which must invest our funds in accordance with our investment policy with the principal objectives of such policy being preservation of capital, fulfillment of liquidity needs and above market returns commensurate with preservation of capital. Our investment policy also requires that investments in marketable securities be in only highly rated instruments, which are primarily US treasury bills or US treasury backed securities, with limitations on investing in securities of any single issuer. We maintain cash balances in excess of federally insured limits in reputable financial institutions. To a limited degree, the Federal Deposit Insurance Corporation and third parties insure these investments. However, these investments are not insured against the possibility of a complete loss of earnings or principal and are inherently subject to the credit risk related to the continued credit worthiness of the underlying issuer and general credit market risks. We manage such risks on our portfolio by investing in highly liquid, highly rated instruments and limit investing in long-term maturity instruments.

Cash, equivalents and marketable securities, including long term bank certificates of deposits, and investments totaled $127.9 million and $145.5 million as of June 30, 2013 and December 31, 2012, respectively. Long term bank certificates of deposit include a $250,000 restricted certificate of deposit that collateralizes tenant improvement obligations to the lessor of our principal offices. The following is a summary of such investments (in 000’s):

	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated fair Value		Cash		Marketable Security

As of June 30, 2013, none of the securities had been in a continuous unrealized loss position longer than one year.

4. Fair Value Measurements

We measure fair value based on the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include the following:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. These inputs include quoted prices for similar assets or liabilities; quoted market 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 are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

21

In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in the assessment of fair value. Cash equivalents consist of certificates of deposit and are valued at cost, which approximates fair value due to the short-term maturities of these instruments. Marketable securities consist of certificates of deposit, US Government Treasury bills, US treasury-backed securities and corporate deposits, which are stated at fair value as it approximates carrying value due to the short term maturities of these instruments.

The fair value of the deferred development cost liability and the deferred payment contingency was valued using the discounted cash flow method of the income approach. The unobservable inputs in the valuation models that have the most significant effect on the fair value of our deferred development cost liability and deferred payment contingency are the determination of the present value factors for future cash flows. The assumptions included internal estimates of research and development personnel needed to perform the research and development services; and estimates of expected cash outflows to third parties for services and supplies over the expected period that the services will be performed, approximately through 2022 for the research and development obligations. We determined the present value factor to be a weighted-average cost of capital of approximately 11.0% in 2013 and 2012.

The fair value of the other long-term liability was classified as Level 3 and valued using the probability of success and the discounted cash flow method of the income approach assuming the FDA approval of Captisol-enabled^® melphalan will occur on or about December 31, 2015.

A majority of our financial assets have been classified as Level 2. These assets have been initially valued at the transaction price and subsequently valued utilizing third party pricing services. The pricing services use many observable market inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. We validate the prices provided by our third party pricing services by understanding the models used, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming those securities trade in active markets.

We did not elect the fair value option, as allowed, to account for financial assets and liabilities that were not previously carried at fair value. Therefore, material financial assets and liabilities that are not carried at fair value, such as trade accounts receivable and payable, are reported at their historical carrying values.

The fair value of the deferred development costs and deferred payment contingency are measured at the end of each reporting period using Level 3 inputs. The significant unobservable assumptions we use include the determination of present value factors for future cash flows.

The carrying values of our cash and cash equivalents, marketable securities, other securities and common stock warrants, carried at fair value as of June 30, 2013 are classified in the table below in one of the three categories of the fair value hierarchy described below:

	Fair Value Measurements ($ in ‘000’s)

5. Revolving Line of Credit

In connection with the Allos Acquisition, we entered into a credit agreement on September 5, 2012, or Credit Agreement, with Bank of America, N.A, as the administrative agent and Wells Fargo Bank, N.A, as an initial lender. The Credit Agreement provides us with a committed $75 million revolving line of credit facility, or Credit Facility. We may increase the Credit Facility up to $125 million, subject to meeting certain customary conditions and obtaining commitments for such increase from the lenders. The Credit Facility expires on September 5, 2014.

The Credit Facility bears interest, at our election, at a rate equal to the London Interbank Offer Rate, or LIBOR rate, or the base rate, plus an applicable margin (4.25% at June 30, 2013). The applicable margin is as follows:

• if the consolidated leverage ratio as of the last test date is less than 0.5:1.0, 1.75% per annum (for LIBOR rate loans) or 0.75% (for base rate loans);

• if the consolidated leverage ratio as of the last test date is greater than 0.5:1.0 but less than 1.0:1.0, 2.00% per annum (for LIBOR rate loans) or 1.00% (for base rate loans); and

• if the consolidated leverage ratio as of the last test date is greater than 1.0:1.0, 2.25% per annum (for LIBOR rate loans) or 1.00% (for base rate loans).

The base rate is subject to a floor that is 100 basis points above the LIBOR rate. The LIBOR rate does not include a floor and, with respect to it, interest periods of 1, 2, 3 and 6 months may be selected. Related interest expense was $572,000 for the six months ended June 30, 2013.

We incurred $976,000 in related loan costs and fees, which were deferred and will be amortized using the effective interest method over 24 months, the term of the Credit Facility. Amortization expense included in interest expense in the accompanying condensed consolidated statements of operations was $244,000 and $0 for the six months ended June 30, 2013 and 2012.

An unused line fee is payable quarterly in an amount ranging from 0.375 to 0.625% of the sum of the average daily unused portion of the facilities during any quarter based upon consolidated leverage ratio as at the last test date. A customary fee is also payable to the administrative agent on an annual basis in advance. Related interest expense for the unused line fee was $118,000 for the six months ended June 30, 2013.

The direct and indirect domestic subsidiaries of the Company, including Allos, as a new wholly-owned subsidiary, guaranty our obligations under the Credit Facility.

23

The Credit Agreement includes the following quarterly financial covenants:

• The Company may not permit the consolidated interest coverage ratio of the Company and its subsidiaries as of the end of any fiscal quarter to be less than 3.00 to 1.00;

• The Company may not permit the consolidated leverage ratio at any time set forth below to be greater than the ratio set forth below opposite such period:

Measurement Period Ending	Maximum Consolidated Leverage Ratio
Closing Date through September 30, 2012		2.00 to 1.00
December 31, 2012 and each fiscal quarter thereafter		1.50 to 1.00

• The Company may not permit the ratio of (i) the sum of (A) unencumbered cash and cash equivalents of the Company and its subsidiaries on a consolidated basis, plus (B) net accounts receivable of the Company and its subsidiaries on a consolidated basis, to (ii) consolidated funded indebtedness as of the end of any fiscal quarter to be less than 2.00 to 1.00.

In addition, the Credit Agreement includes certain negative covenants that, subject to exceptions, limit our ability to, among other things incur additional indebtedness, engage in future mergers, consolidations, liquidations and dissolutions, sell assets, pay dividends and distributions on or repurchase capital stock, and enter into or amend other material agreements. The Credit Agreement also includes certain customary representations and warranties, affirmative covenants and events of default, which are set forth in more detail in the Credit Agreement.

On the closing date of September 5, 2012, we drew $50 million on the Credit Facility and used the proceeds to pay a portion of the purchase price for Allos. At June 30, 2013, $50 million was outstanding on the Credit Facility and there was $25 million available to borrow. At June 30, 2013, we were in compliance with all financial covenants. In July 2013, we repaid $25 million of the then outstanding balance.

Additional revolving loans may be drawn and all revolving loans may be repaid and re-borrowed from time to time in an amount not to exceed the total commitment amount. Any such loan proceeds may be used for working capital and other general corporate purposes for us or our subsidiaries.

Amendment to Credit Agreement

On July 16, 2013, we entered into an amendment to the Credit Agreement dated as of September 5, 2012 with Bank of America, N.A., in its capacity as administrative agent for the lenders and other parties signatory thereto, to, among other things, permit the acquisition of Talon Therapeutics, Inc., reduce the maximum aggregate borrowing amount under the revolving line of credit to $50 million, and to revise the interest rate on borrowings under the revolving line of credit.

6. Intangible Assets and Goodwill

Intangible assets consist of the following ($ in 000’s):

	June 30, 2013 (As Restated)
	Gross Amount		Accumulated Amortization			Foreign Currency Translation			Impairment			Net Amount		Weighted Average Amortization Period (years)

Total intangible assets	$	236,168	$	(37,696	)	$	(663	)		(1,023	)	$	196,786

On May 29, 2013 the Company and Mundipharma entered into an amendment to their collaboration agreement in order to modify the scope of the Mundipharma licensed territories and the respective development obligations of the parties.

24

As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and royalty and milestone rates were modified. The modification of the Company’s associated royalty and milestone rights constituted a change in the contractual provisions under which the Company measured its original acquired intangible asset (FOLOTYN distribution rights) with Mundipharma. The Company determined that an impairment of the Mundipharma intangible asset of $1.0 million resulted from the amendment and is recorded in the amortization and impairment of purchased intangibles in the accompanying statement of operations.

During the six months ended June 30, 2013, ZEVALIN and FOLOTYN intangible amortization of $3.3 million and $5.6 million, respectively, is included in amortization of purchased intangibles. In addition, during the six months ended June 30, 2013, $1.0 million is included in cost of product sales related to FUSILEV milestones.

Goodwill

Goodwill includes the following:

9. Income Taxes

On an interim basis, we estimate that the anticipated annual effective tax rate for the provision for income taxes and record a quarterly income tax provision in accordance with this anticipated annual rate. The effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as the valuation allowances against deferred tax assets, the recognition or derecognition of tax benefits related to uncertain tax positions, expected utilization of R&D tax credits and changes in or the interpretation of tax laws in jurisdictions where the we conduct business. The American Taxpayer Relief Act of 2012 was enacted on January 2, 2013 and retroactively reinstated the U.S. R&D tax credit to January 1, 2012. During the six months ended June 30, 2013 we recognized $0.4 million as a discrete tax benefit due to the retroactive reinstatement of the U.S. R&D tax credit for 2012.

Our provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction by jurisdiction basis, and includes a review of all available positive and negative evidence.

Based on the weight of both positive and negative evidence, we concluded that it is more likely than not that the domestic net deferred tax assets would be realized, and therefore, we released our domestic valuation allowance during the quarter ended March 31, 2012. We released approximately $23 million as part of the projected annual effective tax rate and released the remaining $24 million of the domestic valuation allowance as a discrete item in the quarter ended March 31, 2012. We maintain a valuation allowance against our foreign net deferred tax assets as we continue to conclude it not more likely than not that the foreign net deferred tax assets will be realized.

We recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, we follow the with-and-without approach, excluding any indirect effects of the excess tax deductions. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us.

We recognize the impact of a tax position in our financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense.

10. Mundipharma Agreements

As the result of Allos becoming our wholly owned subsidiary effective September 5, 2012, on a consolidated basis we assumed obligations under a strategic collaboration agreement with Mundipharma, or the Mundipharma Collaboration Agreement, pursuant to which we agreed to collaborate in the development of FOLOTYN according to a mutually agreed-upon development plan, as updated by the parties from time to time. Under the Mundipharma Collaboration Agreement, we retained full commercialization rights for FOLOTYN in the United States and Canada with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world, or the Mundipharma territories.

On May 29, 2013 the Company and Mundipharma entered into an amendment to amend and restate the Collaboration Agreement, referred to as the Amended Collaboration Agreement in order to modify the scope of the licensed territory and the respective development obligations of the parties. As a result of the Amended Collaboration Agreement, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and royalty and milestone rates were modified. In addition, the Company received $7.0 million from Mundipharma. All other terms and conditions remained unchanged from the original collaboration agreement.

Pursuant to the Amended Collaboration Agreement, we may receive potential regulatory milestone payments of up to $16 million and commercial progress- and sales-dependent milestone payments of up to $107 million. All of these remaining potential milestone payments are not deemed to be substantive for accounting purposes and will be recognized when the appropriate revenue recognition criteria have been met. We will also receive tiered double digit royalties based on net sales of FOLOTYN within Mundipharma’s licensed territories consistent with the terms of the original Collaboration Agreement.

26

The Company also entered into a separate supply agreement with Mundipharma Medical Company, an affiliate of Mundipharma, pursuant to which we have agreed to supply FOLOTYN for use in clinical trials for which Mundipharma bears operational responsibility and to support Mundipharma’s commercial requirements. We refer to this as the Mundipharma Supply Agreement, and we refer to the Mundipharma Supply Agreement and the Amended Collaboration Agreement together as the Amended Mundipharma Agreements.

As part of the original Collaboration Agreement, we were obligated to perform research and development services related to jointly agreed-upon clinical development activities through approximately 2022, with cost sharing as discussed below. The Company recorded the fair value of the related deferred development cost obligation of $12.3 as of September 5, 2012, using the discounted cash flow method of the income approach.

In connection with the Amended Collaboration Agreement, the Company determined that the entire $7.0 million development payment from Mundipharma is allocable as arrangement consideration related to the research and development services obligation described above, resulting in an aggregate development cost liability of $18.7 million at June 30, 2013. The development cost liability includes assumptions about internal estimates of research and development personnel needed to perform the research and development services; and estimates of expected cash outflows to third parties for services and supplies for our projected clinical trial enrollment and patient treatment-related follow up time periods through approximately 2031. As with the Company’s previous accounting for the development cost liability, the Company will reevaluate the measurement of this liability at each subsequent reporting date and record the change in measurement to research and development expense.

Under the original Collaboration Agreement, Mundipharma was initially responsible for 40% of the joint development costs incurred by the parties, which increased to 50% upon the later of (i) the calendar quarter of the first approval of FOLOTYN in the EU for relapsed or refractory PTCL or first-line PTCL, and (ii) the first calendar quarter in which the development cost differential equals or exceeds $15.0 million. The “development cost differential” was defined as the cumulative amount of joint development costs that Mundipharma would have incurred if it was responsible for 50% of the joint development costs rather than its initial 40% share. To the extent that this development cost differential did not meet or exceed $15.0 million by December 31, 2019, then the Company was obligated to pay Mundipharma the difference between $15.0 million and the amount of the development cost differential as of December 31, 2019. The Company recorded the joint development cost reimbursements received from Mundipharma as research and development in the statement of operations; and we record the full amount of our joint development costs as research and development expense. Research and development for the three and six months ended June 30, 2013 included $268,000 and $589,000, respectively, related to the 40% joint development cost reimbursement under the original Collaboration Agreement.

The Amended Collaboration Agreement eliminated the development cost differential computation requirement. Prospectively, the Company and Mundipharma will bear their own development costs. The Amended Collaboration Agreement required Spectrum to compute the remaining development cost differential amount which was $12,099 as of May 31, 2013. The Company determined that the remaining development cost differential liability pursuant to the Amended Collaboration Agreement was $18.7 million which is included in the Company’s balance sheet at June 30, 2013. As a result of the amendment, Spectrum reevaluated the fair value measurement of the related contingent payment obligation and determined that its fair value was zero, as no remaining contingent obligation remained at May 29, 2013. Therefore, the Company recorded the difference between the carrying value and the new fair value of the related contingent payment obligation of $2.4 million at May 29, 2013 to research and development expense in the accompanying statement of operations.

As of June 30, 2013, accounts receivable related to the Mundipharma Agreements totaled $24,000. As of June 30, 2013 and December 31, 2012, deferred amounts related to the Mundipharma Agreements consisted of ($ in 000’s):

	June 30, 2013		December 31, 2012
Deferred development cost liability	$	3,251	$	856
Deferred development cost liability, less current portion		15,400		11,377
Deferred payment contingency		—		2,287
	$	18,651	$	14,520

11. Commitments and Contingencies

Facility Lease

We sublease our principal executive office in Henderson, Nevada under a non cancelable operating lease expiring April 30, 2014. We also lease our research and development facility in Irvine, California under a non cancelable operating lease expiring June 30, 2016. Each lease agreement contains certain scheduled rent increases which are accounted for on a straight-line basis.

As part of our Irvine facility lease renewal in 2009, the landlord agreed to contribute up to approximately $1.5 million toward the cost of tenant improvements. The tenant improvements were completed in 2010 at an aggregate cost of approximately $1.4 million, of which, $451,000 is being financed. This landlord contribution is being amortized on a straight-line basis over the term of the lease as a reduction to rent expense. We also lease small administrative offices in Colorado, New Jersey, Westlake Village (California), Tokyo, Japan and Mumbai, India.

Licensing Agreements

We are developing almost all of our drug candidates pursuant to license agreements that provide us with rights in certain territories, among other things, to develop, sublicense, manufacture and sell the drugs. We are generally required to use commercially reasonable efforts to develop the drugs, and are generally responsible for all development, patent filing and maintenance, sales and marketing and liability insurance costs, and are generally contingently obligated to make milestone payments to the licensors if we successfully reach development and regulatory milestones specified in the license agreements. In addition, we are obligated to pay royalties and, in some cases, milestone payments based on net sales, if any, after marketing approval is obtained from regulatory authorities.

The potential contingent development and regulatory milestone obligations under all of our licensing agreements are generally tied to progress through the various regulatory authorities’ approval process, which approval significantly depends on positive clinical trial results. The following items are typical of such milestone events: conclusion of Phase 2 or commencement of Phase 3 clinical trials; filing of new drug applications in each of the United States, Europe and Japan; and approvals from each of the regulatory agencies in those jurisdictions.

ZEVALIN licensing and development in the United States

In December 2008, we acquired rights to commercialize and develop ZEVALIN in the United States as the result of a transaction with Cell Therapeutics, Inc. (“CTI”). Pursuant to the transfer of the ZEVALIN assets from CTI to a joint venture, RIT Oncology LLC (“RIT”), in December 2008, RIT assumed certain agreements with various third parties related to ZEVALIN intellectual property. These currently effective agreements relate to the manufacture, use and sale of ZEVALIN in the United States and include (i) a license from Biogen, Idec, Inc. (“Biogen”) (ii) a license-back to Biogen for limited uses including fulfillment of a supply obligation to CTI, (iii) a sublicense from Biogen to certain ZEVALIN patents held by Genentech, Inc., (iv) a sublicense from Biogen to certain ZEVALIN patents held by GlaxoSmithKline and Glaxo Group Limited, and (v) a sublicense from Biogen to certain ZEVALIN patents held by Corixa Corporation, Coulter Pharmaceutical, Inc., The Regents of the University of Michigan and GlaxoSmithKline.

In accordance with the terms of such agreements, RIT is required to meet specified payment obligations including a commercial milestone payment to Corixa Corporation of $5.0 million based on ZEVALIN sales in the United States, which has not been met as of June 30, 2013, as well as U.S. net sales-based royalties of low to mid-single digits to Genentech, Inc. and mid-single digits to Corixa Corporation. Such agreements generally continue until the last to expire of the licensed patents unless earlier terminated in accordance with the terms of the agreement for bankruptcy or material breaches that remain uncured. The patents that are subject to the agreements expire between 2014 and 2019.

Asset Purchase Agreement between CTI and Biogen, ZEVALIN U.S.

In connection with the joint venture arrangement with CTI, we entered into an amendment to the original asset purchase agreement between CTI and Biogen, referred to as the CTI/Biogen Agreement, modifying future milestone payments. Pursuant to the terms of the agreement, as amended, (i) upon the achievement of the specified FDA approval milestone, which was achieved in 2009, RIT (as successor to CTI) paid Biogen an additional amount of $5.5 million, (ii) RIT may be required to make an additional $10.0 million milestone payment upon the achievement of an additional FDA approval milestone, and (iii) RIT is required to make yearly royalty payments determined as a mid-single to mid-teen digits percentage of yearly net sales for the preceding year, increasing with the passage of time, with specific rates subject to confidential treatment pursuant to an order by the SEC. The agreement has an indefinite term and is no longer subject to termination; provided, however, that the royalty obligations automatically terminate upon the latest to occur of expiration of the subject patents, the sale by a third party of a biosimilar product in the U.S. or December 31, 2015. CTI’s rights and obligations, including its payment obligations to Biogen for royalties on net sales of ZEVALIN and an additional regulatory milestone payment, under both the CTI/Biogen Agreement and the amendment were assigned to and assumed by RIT in connection with the closing of the joint venture transaction.

Supply Agreement between Biogen and CTI, ZEVALIN U.S.

In connection with the joint venture arrangement with CTI, we entered into an amendment to the original supply agreement between Biogen and CTI, referred to as the CTI/Biogen Supply Agreement, modifying certain of the pricing and manufacturing technology transfer terms contained in the CTI/Biogen Supply Agreement and also providing that the term of the agreement may be shortened in some instances in the event of a mid-term manufacturing technology transfer. There are no milestone or royalty payments required pursuant to this agreement. The term of the agreement is until the manufacturing technology transfer is complete. Either party may generally terminate this agreement due to a bankruptcy of the other party or due to such other party’s material noncompliance with the agreement or certain other related agreements. CTI’s rights and obligations, including its payment obligations to Biogen, under both the CTI/Biogen Supply Agreement and the amendment were assigned to and assumed by RIT in connection with the closing of the joint venture transaction.

License and Asset Purchase Agreement with Bayer Pharma, ZEVALIN Ex—U.S.

On April 1, 2012, through a subsidiary, Spectrum Pharmaceuticals Cayman, L.P., we completed the acquisition of licensing rights to market ZEVALIN outside of the U.S., referred to as the ZEVALIN Ex-US Rights, from Bayer Pharma AG, or Bayer. Pursuant to the terms of the agreement, Spectrum acquired all rights including marketing, selling, intellectual property and access to existing inventory of ZEVALIN from Bayer. We currently market ZEVALIN in the U.S. and this agreement expands our commercial efforts to the rest of the world. ZEVALIN is currently approved in more than 40 countries outside the U.S. for the treatment of B-cell non-Hodgkin lymphoma, including countries in Europe, Latin America and Asia. In consideration for the rights granted under the agreement, concurrent with the closing, Spectrum paid Bayer a one-time fee of Euro 19 million or approximately USD $25.4 million, and will pay Bayer royalties based on a mid-teen digits percentage of net sales of the licensed products in all territories worldwide except the U.S., with specific rates subject to confidential treatment pursuant to an order by the SEC. Under the agreement, we also acquired access to existing inventory of ZEVALIN and concurrent with the closing, entered into certain ancillary agreements including but not limited to a transition services agreement to transition the business. Unless earlier terminated, the term of the agreement continues until the expiration of our royalty payment obligations which, in turn, run until the last-to-expire patent covering the sale of a licensed product in the relevant country or fifteen (15) years from the date of first commercial sale of the licensed product in such country, whichever is longer. This agreement may be terminated in the event of a material default, which is defined to include: (i) our failure to timely pay royalty payments under this agreement or payments under certain related agreements; (ii) our insolvency; and (iii) our breach and the resulting termination of an Amended and Restated License Agreement between Biogen and Bayer, dated as of January 16, 2012.

Amended and Restated License Agreement with Merck & Cie AG, FUSILEV.

In May 2006, we amended and restated a license agreement with Merck & Cie AG, a Swiss corporation, which we assumed in connection with the acquisition of the assets of Targent. Pursuant to the license agreement with Merck & Cie, we obtained the exclusive license to use regulatory filings related to FUSILEV and a non-exclusive license under certain patents and know-how related to FUSILEV to develop, make, and have made, use, sell and have sold FUSILEV in the field of oncology in North America. In addition, we have the right of first opportunity to negotiate an exclusive license to manufacture, have manufactured, use and sell FUSILEV products outside the field of oncology in North America. Also, under the terms of the license agreement, we paid Merck & Cie $100,000 for the achievement of FDA approval of an injectable form of FUSILEV. Merck & Cie is also eligible to receive a $200,000 payment upon achievement of FDA approval of an oral form of FUSILEV, in addition to royalties in the mid-single digits based on a percentage of net sales. The term of the license agreement is determined on a product-by-product and country-by-country basis until royalties are no longer owed under the license agreement. The license agreement expires in its entirety after the date that we no longer owe any royalties to Merck & Cie. We have the unilateral right to terminate the license agreement, in its entirety or on a product-by-product or country-by-country basis, at any time for any reason and either party may terminate the license agreement due to material breach of the terms of the license agreement by or insolvency of the other party.

Asset Purchase Agreement with Targent, Inc., FUSILEV

In March 2006, we entered into an Asset Purchase Agreement with Targent, Inc. (“Targent”). As part of the consideration for the purchase of certain assets, we agreed to pay milestone payments to Targent upon the achievement of certain regulatory events as well as for certain sales levels for FUSILEV within a calendar year. In connection with the achievement of the FDA approval milestone in April 2011, we issued an aggregate of 733,715 shares of common stock to certain of Targent’s stockholders, as directed by Targent. We capitalized $6.3 million associated with this milestone as intangible assets during 2011 which is being amortized over the estimated useful life of 8.7 years.

In addition, in connection with the achievement of the first sales milestone of $40 million in May 2011 we issued 577,367 shares of common stock to certain of Targent’s stockholders (which was equivalent value to approximately $5 million in cash), as directed by Targent. In September 2011, we achieved the second and final sales milestone of $100 million and paid $5 million in cash for an aggregate with the first sales milestone of $10.0 million. We capitalized the $10.0 million associated with these milestones as intangible assets. These intangible assets are being amortized over the estimated useful life of 8.6 years. As of December 2011, we have met all of the contractual milestones related to FUSILEV.

License Agreement with Sloan-Kettering Institute, SRI International and Southern Research Institute, FOLOTYN

In December 2002, Allos entered into the FOLOTYN License Agreement with Sloan-Kettering Institute for Cancer Research, SRI International and Southern Research Institute. As a result of Allos becoming our wholly owned subsidiary effective September 5, 2012, on a consolidated basis we are bound by the FOLOTYN License Agreement under which we obtained exclusive worldwide rights to a portfolio of patents and patent applications related to FOLOTYN and its uses. Under the terms of the FOLOTYN License Agreement, we are required to fund all development programs and will have sole responsibility for all commercialization activities. In addition, we pay the licensors royalties based on worldwide graduated annual levels of net sales of FOLOTYN, net of actual rebates, chargebacks and returns, or distributor sales, which may be different than our net product revenue recognized in accordance with U.S. generally accepted accounting principles, or GAAP, or sublicense revenues arising from sublicensing the product, if and when such sales or sublicenses occur. For purposes of the FOLOTYN License Agreement, annual worldwide sales consists of our distributor sales and annual net sales of FOLOTYN in the Mundipharma Territories, as reported to us under the Mundipharma Collaboration Agreement, if and when such sales occur in the Mundipharma Territories. Royalties are 8% of annual worldwide sales up to $150.0 million; 9% of annual worldwide sales of $150.0 million through $300.0 million; and 11% of annual worldwide sales in excess of $300.0 million. For the six months ended June 30, 2013, our royalties were 8% of our net distributor sales. As of June 30, 2013, accrued royalties were $1.2 million and are included in accounts payable and accrued obligations on the consolidated balance sheet.

Exclusive Development and Commercialization Collaboration Agreement with Allergan, apaziquone

In October 2008, we signed an exclusive development and commercialization collaboration agreement with Allergan for apaziquone. Pursuant to the terms of the agreement, Allergan paid us an up-front non-refundable $41.5 million at closing and is obligated to make additional payments based on the achievement of certain development, regulatory and commercialization milestones. Under the terms of the original agreement, we were entitled to payment of $57.5 million and $245 million upon achievement of certain regulatory and commercialization milestones, respectively, of which $1.5 million has been achieved following completion of enrollment in clinical trials, per the terms of the license, development, supply and distribution agreement. Also, Allergan agreed to pay us tiered royalties starting in the mid-teens based on a percentage of net sales of apaziquone outside of the U.S. and Asia, which specific rates are subject to confidential treatment pursuant to an order by the SEC.

On January 29, 2013, we entered into a second amendment to the license, development, supply and distribution agreement with Allergan to amend the agreement and reacquire the rights originally licensed to Allergan in the U.S. Europe and other territories in exchange for a tiered single digit royalty on certain products containing Apaziquone, and relieved Allergan of its obligations for development, commercialization and other activities. As a result of the second amendment to the agreement with Allergan, Allergan has no remaining obligations to the Company and Spectrum has no remaining performance obligations to Allergan. However, the Company is obligated to pay Allergan a tiered single-digit royalty not to exceed mid-single digits based upon the net sales, when and if earned, of certain products containing Apaziquone in specified territories. Additionally, the Company is obligated to pay any royalties or other payments due to licensors of the Licensed Intellectual Property (as defined in the agreement) as well as to provide indemnification of Allergan for claims arising from the manufacture, development or commercialization of pharmaceutical products containing Apaziquone by the Company. We recognized $8.3 million, the remaining balance of deferred revenue related to this agreement, during the three months ended March 31, 2013 and six months ended June 30, 2013.

Collaboration Agreement with Nippon Kayaku Co. LTD., apaziquone

In November 2009, we entered into a collaboration agreement with Nippon Kayaku Co., LTD. (“Nippon Kayaku”) for the development and commercialization of apaziquone in Asia, except North and South Korea (the “Nippon Kayaku Territory”). In addition, Nippon Kayaku received exclusive rights to apaziquone for the treatment of non muscle invasive bladder cancer in Asia (other than North and South Korea), including Japan and China. Nippon Kayaku will conduct apaziquone clinical trials in the Nippon Kayaku Territory pursuant to a development plan. Further, Nippon Kayaku will be responsible for all expenses relating to the development and commercialization of apaziquone in the Nippon Kayaku Territory.

Pursuant to the terms of this agreement, Nippon Kayaku paid Spectrum an upfront fee of $15 million and is obligated to make additional payments based on the achievement of certain development, regulatory and commercialization milestones. Under the terms of the agreement, we are entitled to payment of $10 million and $126 million upon achievement of certain regulatory and commercialization milestones, respectively. Also, Nippon Kayaku has agreed to pay Spectrum royalties based on a percentage of net sales of the subject products in the defined territory in the mid-teen digits, which specific royalty rates are subject to confidential treatment pursuant to an order by the SEC. The agreement will remain in effect, on a country-by-country basis, until the expiration of the obligation of Nippon Kayaku to pay royalties on sales of the subject products in such country. Nippon Kayaku may terminate the agreement at its election upon nine months notice to Spectrum. Additionally, either party may terminate the agreement for an uncured material breach by the other party.

Our license agreement with Nippon Kayaku provides for payments to us upon the achievement of development milestones, such as the completion of clinical trials or regulatory submissions, approvals by health authorities, and commercial launches of drug candidates. Given the challenges inherent in developing and obtaining approval for drug products and in achieving commercial launches, there was substantial uncertainty whether any such milestones would be achieved at the time of execution of such license agreement. In addition, we continue to evaluate whether the development milestones, none of which have been achieved to date, meet the remaining criteria to be considered substantive. As a result of our analysis, we consider our development milestones under the Nippon Kayaku license agreement to be substantive and, accordingly, we expect to recognize as revenue future payments received from such milestones only if and as each milestone is achieved.

Licensing and Collaboration Agreement with TopoTarget, belinostat

In February 2010, we entered into a licensing and collaboration agreement with TopoTarget, for the development and commercialization of belinostat, pursuant to which we agreed to collaboration for the development and commercialization of belinostat. The agreement provides that we have the exclusive right to make, develop and commercialize belinostat in North America and India, with an option for China. The agreement also grants TopoTarget a co-promote option if and only if we do not maintain a minimum number (subject to adjustment for certain events outside of our control) of field personnel (as defined in the agreement) for a certain number of years post-approval of the PTCL indication.

Under the terms of the agreement, all development, including studies, will be conducted under a joint development plan and in accordance with a mutually agreed upon target product profile provided that we have final decision-making authority for all developmental activities in North America and India (and China upon exercise of the option for China) and TopoTarget has final decision-making authority for all developmental activities in all other jurisdictions. We have agreed to assume all responsibility for and future costs of the ongoing registrational PTCL trial. We and TopoTarget will conduct future planned clinical trials pursuant to the joint development plan, of which we will fund 70% of the development costs and TopoTarget will fund 30% of the development costs. We and TopoTarget will each pay 50% of the costs for chemical, pharmaceutical and other process development related to the manufacturing of the product that are incurred with a mutually agreed upon budget in the joint development plan. TopoTarget is responsible for supplying us with both clinical and commercial product.

Pursuant to the terms of this agreement, Spectrum paid TopoTarget an upfront fee of $30 million. In addition, on the successful achievement of certain development, regulatory and sales milestones, none of which have been achieved to date, Spectrum is obligated to issue one million (1,000,000) shares of its common stock (subject to certain resale conditions) and pay TopoTarget up to $313 million. Also, Spectrum will pay TopoTarget royalties in the mid-teen digits based on net sales of the subject product in the defined territory, which specific royalty rates are subject to confidential treatment pursuant to an order by the SEC. None of such royalties have been earned or paid since inception of the agreement.

The agreement will continue until the expiration of the last royalty payment period in the last country in the defined territory with certain provisions surviving, unless earlier terminated in accordance with its terms. Spectrum may terminate the agreement at its election upon one hundred eighty (180) days notice to TopoTarget. Generally, Spectrum may also terminate immediately upon a prohibition on the use of the subject product or clinical hold by the FDA. TopoTarget may also terminate immediately in the event of a challenge (without TopoTarget’s consent) by Spectrum of the patents that cover the product. Either party may terminate the agreement upon a bankruptcy by the other party, or in the event of an uncured material breach by the other party.

Co-Development and Commercialization Agreement with Hanmi Pharmaceutical Company, SPI-2012

In late January 2012, we entered into a co-development and commercialization agreement with Hanmi Pharmaceutical Company, (“Hanmi”), for SPI-2012, formerly known as “LAPS-GCSF”, a drug for the treatment of chemotherapy induced neutropenia based on Hanmi’s proprietary LAPSCOVERY™ Technology. In consideration for the rights granted to us under the co-development and commercialization agreement with Hanmi, we paid Hanmi a fee which is included in research and development expense in the accompanying condensed consolidated financial statements because the technology has not yet achieved regulatory approval. We expect to initiate Phase 2 trials in collaboration with Hanmi in 2013. Under the terms of the agreement, we will share the costs and expenses of the study although we will have primary responsibility for them. If SPI-2012 is ultimately commercialized by us, we will have worldwide rights except for Korea, China and Japan upon payment of fees and milestone payments related to further development, regulatory approvals and sales targets.

Service Agreements

In connection with the research and development of our drug products, we have entered into contracts with numerous third party service providers, such as radio-pharmacies, distributors, clinical trial centers, clinical research organizations, data monitoring centers, and with drug formulation, development and testing laboratories. The financial terms of these agreements are varied and generally obligate us to pay in stages, depending on achievement of certain events specified in the agreements, such as contract execution, reservation of service or production capacity, actual performance of service, or the successful accrual and dosing of patients.

32

At each period end, we accrue for all costs of goods and services received, with such accruals based on factors such as estimates of work performed, patient enrollment, completion of patient studies and other events. We are in a position to accelerate, slow-down or discontinue any or all of the projects that we are working on at any given point in time. Should we decide to discontinue and/or slow-down the work on any project, the associated costs for those projects would be limited to the extent of the work completed. Generally, we are able to terminate these contracts due to the discontinuance of the related project(s) and thus avoid paying for the services that have not yet been rendered and our future purchase obligations would reduce accordingly.

Supply Agreements

In connection with our acquisition of ZEVALIN, RIT assumed a supply agreement with Biogen Idec Inc., or Biogen, to manufacture ZEVALIN for sale in the U.S. pursuant to which we would purchase from Biogen, and Biogen would provide to us, kits to make ZEVALIN doses for sale to end-users in the U.S. at a “cost plus” manufacturing price. In connection with our acquisition of Captisol-enabled melphalan, we entered into a supply agreement with Ligand pursuant to which, subject to certain exceptions, we agreed to purchase our requirements of Captisol from Ligand.

Employment Agreement

We have entered into an employment agreement with Dr. Rajesh C. Shrotriya, our Chairman, President and Chief Executive Officer, which expires January 2, 2014. The employment agreement automatically renews for subsequent one-year calendar terms unless either party gives written notice of such party’s intent not to renew the agreement at least 90 days prior to the commencement of the new term. The employment agreement requires Dr. Shrotriya to devote his full working time and effort to our business and affairs during the term of the agreement. The employment agreement provides for a minimum annual base salary with annual increases, periodic bonuses and option grants as determined by the Compensation Committee of our Board of Directors.

SEC Subpoena

On April 1, 2013, the Company received a subpoena from the Securities and Exchange Commission (the “SEC”) for documents pursuant to a formal order of investigation. The subpoena followed the Company’s March 12, 2013 announcement that it anticipated a change in ordering patterns of FUSILEV. The Company is cooperating with the SEC investigation. The Company cannot predict when the SEC will conclude its investigation or the outcome of the investigation.

We are involved with various legal matters arising in the ordinary course of business. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our condensed consolidated results of operations, cash flows or financial condition.

Total share based compensation expense	$	2,924	$	3,082	$	5,671	$	6,097

Stock Options

During the three and six month period ended June 30, 2013, the Compensation Committee of our Board of Directors granted stock options at exercise prices equal to or greater than the closing price of our common stock on the trading day prior to the grant date. The weighted average grant date fair value of stock options granted during the six month period ended June 30, 2013 and 2012 were estimated at approximately $8.71 and $7.57, respectively using the Black-Scholes option pricing model with the following assumptions:

	Six-months ended June 30,
	2013			2012
Divided yield		0.00	%		0.00	%
Expected volatility		69.5	%		72.1	%
Risk free interest rate		0.35	%		0.40	%
Expected life (years)		4.95			4.50

Share based compensation expense is recognized only for those awards that are ultimately expected to vest, and we have applied a forfeiture rate to unvested awards for the purpose of calculating the compensation cost. These estimates will be reversed in future periods if actual forfeitures differ from our estimates.

35

During the three and six months ended June 30, 2013, our share-based charge in connection with the expensing of stock options was approximately $1.6 million and $3.0 million, respectively. During the three and six months ended June 30, 2012, our share-based compensation in connection with the expensing of stock options was approximately $1.3 million and $2.6 million, respectively.

As of June 30, 2013, there was approximately $12.2 million of unrecognized stock-based compensation cost related to stock options which we expect to recognize over a weighted average period of approximately 2.41 years.

Restricted Stock

The fair value of restricted stock awards is the grant date closing market price of our common stock, and is charged to expense over the period of vesting. These awards are subject to forfeiture to the extent that the recipient’s service is terminated prior to the shares becoming vested.

During the three and six month periods ended June 30, 2013, the share-based charge in connection with the expensing of restricted stock awards was approximately $1.1 million and $2.0 million, respectively. During the three and six month periods ended June 30, 2012, the share-based compensation in connection with the expensing of restricted stock awards was approximately $1.3 million and $2.5 million, respectively.

As of June 30, 2013, there was approximately $6.7 million of unrecognized share-based compensation cost related to non-vested restricted stock awards, which is expected to be recognized over a weighted average period of approximately 2.67 years.

401(k) Plan Matching Contribution

During the six month period ended June 30, 2013, we issued 50,970 shares of common stock as our matching contribution of approximately $446,000 for 401(k) contributions made by our employees. During the six month period ended June 30, 2012, we issued 26,154 shares of common stock as our matching contribution of approximately $333,500 for 401(k) contributions made by our employees.

Employee Stock Purchase Plan

Effective July 2009, we adopted the 2009 Employee Stock Purchase Plan (“Purchase Plan”). The Purchase Plan provides our eligible employees with an incentive by providing a method whereby they may voluntarily purchase shares of our common stock upon terms described in the Purchase Plan. The Purchase Plan is designed to be operated on the basis of six consecutive month offering periods commencing January 1 and July 1 of each year. The Purchase Plan provides that eligible employees may authorize payroll deductions to purchase shares of our common stock at 85% of the fair market value of common stock on the first or last day of the applicable purchase period. A participant may purchase a maximum of 50,000 shares of common stock during a 6-month offering period, not to exceed $25,000 worth of stock on the offering date during each plan year. The Purchase Plan terminates in 2019.

A total of 5,000,000 shares of common stock are authorized for issuance under the Purchase Plan, and as of June 30, 2013, 420,046 shares have been issued under the Purchase Plan.

Common Stock Reserved for Future Issuances

As of June 30, 2013, approximately 16.3 million shares of our common stock, when fully vested, were issuable upon conversion or exercise of rights granted under prior financing arrangements, stock options and warrants, as follows:

Conversion of Series E preferred shares	40,000
Exercise of stock options	10,932,574
Exercise of warrants	445,000
Employee stock purchase plan shares reserved for issuance	4,579,954
Long-term retention and management incentive plan shares reserved for issuance	346,500
Total shares of common stock reserved for future issuances	16,344,028

13. Deferred Compensation Plan

On September 2, 2011, the Board of Directors approved the Spectrum Pharmaceuticals, Inc. Deferred Compensation Plan (the “Plan”). The Plan is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended. The Plan is administered by the Compensation Committee of the board of directors, or a designee or designees of the Compensation Committee. The Plan is intended to be an unfunded plan which is maintained primarily to provide deferred compensation benefits for a select group of our employees including management, as selected by the Plan administrator (the “Participants”). Under the Plan, we provide the Participants with the opportunity to make annual elections to defer up to a specified amount or percentage of their eligible cash compensation, as established by the Plan administrator, and we have the option to make discretionary contributions. At June 30, 2013, deferrals and contributions totaling $3.2 million are included in other accrued obligations in the accompanying condensed consolidated balance sheet.

14. Gross to Net Product Sales

15. Subsequent Event

Talon Therapeutics Acquisition

On July 16, 2013, the Company entered into a Securities Purchase Agreement with Eagle Acquisition Merger Sub, Inc., a wholly-owned subsidiary of our company which we refer to herein as Acquisition Sub, and certain stockholders of Talon Therapeutics, Inc., or Talon, whereby, on July 17, 2013, Acquisition Sub purchased all of the shares of common stock of Talon owned by such stockholders, which represented approximately 89% of the outstanding shares of common stock of Talon. On July 16, 2013, we also entered into a Stock Purchase Agreement with Acquisition Sub and Talon, whereby, on July 17, 2013, Acquisition Sub purchased additional shares of common stock from Talon, resulting in Acquisition Sub’s ownership of over 90% of the then outstanding shares of Talon’s common stock. On July 17, 2013, Acquisition Sub consummated a “short form” merger with Talon in accordance with Delaware law in which Acquisition Sub merged with and into Talon, with Talon remaining as the surviving corporation and a wholly-owned subsidiary of the Company. Through the acquisition of Talon, we will gain worldwide rights to Marqibo, an FDA-approved drug that we believe complements our other hematology and oncology products.

In connection with the closing of the acquisition, Spectrum will pay Talon stockholders purchase consideration comprising of an aggregate upfront cash consideration of approximately $11.3 million and issued 3 million shares of its common stock (valued at $8.77 on NASDAQ on July 16, 2013 or approximately $26.3 million) in exchange for the cancellation of all of the outstanding indebtedness under Talon’s credit facility. Talon stockholders will also receive contingent value rights (CVRs) in an aggregate of up to $195.0 million in future cash payments from Spectrum upon the achievement of certain one-time sales-based milestones for Marqibo^® and an approval-based milestone for Menadione Topical Lotion upon satisfaction of the following specific milestones, of which there is no assurance that any may be achieved:

• $5,000,000 upon the achievement of net sales of Marqibo (vincristine sulfate liposome injection) in excess of $30,000,000 in any calendar year;

• $10,000,000 upon the achievement of net sales of Marqibo in excess of $60,000,000 in any calendar year

• $25,000,000 upon the achievement of net sales of Marqibo in excess of $100,000,000 in any calendar year

• $50,000,000 upon the achievement of net sales of Marqibo in excess of $200,000,000 in any calendar year

• $100,000,000 upon the achievement of net sales of Marqibo in excess of $400,000,000 in any calendar year

37

• $5,000,000 upon receipt of marketing authorization from the FDA regarding Menadione Topical Lotion

The CVRs have an estimated fair value of $6.5 million on the date of the acquisition and will not be publicly traded. The Company also entered into a Registration Rights Agreement pursuant to which we filed a registration statement for purpose of registering for resale under the Securities Act of all the shares of our common stock issued in connection with the cancellation of the indebtedness.

Consideration Transferred

The Talon acquisition purchase price was allocated to tangible and intangible assets acquired and liabilities assumed based upon their estimated fair value at the acquisition date. The following table summarizes the purchase price ($ in 000’s):

Cash consideration	$	11.3
Contingent value right		6.5
Spectrum shares of common stock		26.3
Total purchase consideration	$	44.1

Fair Value Estimate of Assets Acquired and Liabilities Assumed

Under the purchase method of accounting, the total purchase consideration is allocated to Talon net tangible and intangible assets based on the preliminary estimated fair values as of the closing date. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was allocated to goodwill. The goodwill acquired is not deductible for tax purposes. The following table summarizes the fair value of the net assets acquired as of July 17, 2013 ($ in 000’s):

Cash and equivalents	$	131
Inventory		611
Prepaid expenses and other current assets		602
Property and equipment		30
Identifiable intangible assets		46,300
Goodwill		20,606
Total assets acquired		68,280
Accounts payable & accrued liabilities		6,870
Contingent value rights		6,500
Deferred tax liability		17,300
Total liabilities assumed		30,670
Net assets acquired	$	37,610

The acquired Marqibo intangible assets consisted of developed technology and in-process research and development for the treatment of acute lymphoblastic leukemia (“ALL”) and non-Hodgkin’s lymphoma (“NHL”) as follows in the table below ($ in 000’s):

	Value of Intangible Assets Acquired		Weighted-Average Amortization Period
Developed technology—Marqibo for ALL	$	27,800		(1)
In-process research and development—Marqibo for NHL		18,500		(1)
Total identifiable intangible assets	$	46,300

(1) Acquired in-process research and development (“IPR&D”) is an intangible asset classified as an indefinite-lived until the completion or abandonment of the associated R&D effort, and will be amortized over an estimated useful life to be determined at the date the project is completed. Intangible IPR&D is not amortized during the period that it is considered indefinite-lived but rather tested for impairment.

38

Purchase price adjustments recorded subsequent to the closing date of July 17, 2013 will affect the recorded amount of goodwill.

The fair value of the acquired in-process research and development intangible assets was estimated using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value considered our estimates of future incremental earnings that may be achieved by the intangible assets.

Goodwill is calculated as the excess of the purchase consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisition of Talon includes benefits that the Company believes will result from combining the operations of Talon with the operations of Spectrum and any intangible assets that do not qualify for separate recognition. The Talon acquisition will also allow us to gain additional expertise and intellectual property for the next generation of anti-cancer therapeutics, an expanded and complimentary product mix, and an assembled sales force, which we believe supports the amount of goodwill recognized. Goodwill is not amortized and is not deductible for tax purposes.

Deferred tax liability reflects taxes associated with the acquired in-process research and development assets recognized as part of the acquisition.

With respect to the acquisition discussed above, we believe the preliminary fair values assigned to the assets acquired and liabilities assumed were based upon reasonable assumptions. Actual adjustments will be based on analyses of fair values of identifiable intangible assets, which will be completed after Spectrum obtains a final third-party valuation, performs its own assessments and reviews all available data. The fair value estimates for the purchase price allocation may change if additional information becomes available and could have a material impact.

Proforma information for March 31, 2013 (the last period Talon reported earnings on Form 10-Q) and December 31, 2012 was filed on Form 8K-A on August 6, 2013. There are no Talon revenues and earnings included in the results of the Company for the three and six month period ending June 30, 2013.

We do not plan to update any such forward-looking statements and expressly disclaim any duty to update the information contained in this report except as required by law.

You should read the following discussion of our financial condition and results of our operations in conjunction with the condensed consolidated financial statements and the notes to those financial statements included in Item I of Part 1 of this quarterly report and our audited consolidated financial statements and related notes for the year ended December 31, 2012 included in our Annual Report on Form 10-K filed with the SEC.

As discussed in Note 1A, “Restatement of Condensed Consolidated Financial Statements,” of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q, we have restated in this Form 10-Q, our unaudited condensed consolidated financial statements for the three and six months ended June 30, 2013 and 2012 and balance sheet as of December 31, 2012. Specifically, we have restated our Condensed Consolidated Financial Statements as a result of certain errors related to our accounting for certain business combinations, and the conclusion that the indefinite-lived intangible asset acquired and recognized during the acquisition of Allos Therapeutics, Inc. in September 2012 as in-process research & development (IPR&D) should have instead been recognized at the acquisition date as a definite-lived intangible asset. The financial statements for the restated periods also reflect certain other immaterial adjustments. The combined impact of these adjustments to the applicable line items in our accompanying Condensed Consolidated Financial Statements is set forth in Note 1A.

Management has also concluded that as of June 30, 2013, our internal controls over financial reporting were not effective due to a material weakness in our controls over our accounting for and reporting of accounts payable and other accrued obligations. See “Controls and Procedures” included in Part II, Item 4 of this Quarterly Report on Form 10-Q.

Business Outlook

We are a biotechnology company with fully integrated commercial and drug development operations with a primary focus in hematology and oncology. Our strategy is comprised of acquiring, developing and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. In the United States, or the U.S., we market three oncology drugs, FUSILEV^®, FOLOTYN^® and ZEVALIN^®, and also market ZEVALIN outside of the U.S. We have two drugs, apaziquone and belinostat, in late stage development along with a diversified pipeline of novel drug candidates. We have assembled an integrated in-house scientific team, including formulation development, clinical development, medical affairs, regulatory affairs, biostatistics and data management, and have established a commercial infrastructure for the marketing of our drug products. We also leverage the expertise of our worldwide partners to assist in the execution of our strategy. Apaziquone was studied in two large Phase 3 clinical trials for non-muscle invasive bladder cancer, or NMIBC, and is under strategic collaborations with Nippon Kayaku Co. Ltd., or Nippon Kayaku, and Handok Pharmaceuticals Co. Ltd., or Handok. Belinostat, is being studied in multiple indications including a Phase 2 registrational trial for relapsed or refractory peripheral T-cell lymphoma, or PTCL, and is under a strategic collaboration with TopoTarget A/S, or TopoTarget. FOLOTYN is being further developed under a collaboration agreement with Mundipharma International Corporation Limited, or Mundipharma.

Our business strategy is comprised of the following initiatives:

• Maximizing the growth potential of our marketed drugs, FUSILEV, FOLOTYN and ZEVALIN. Our near-term outlook largely depends on sales and marketing successes for our three marketed drugs. For FUSILEV, we are working to expand usage in colorectal cancer. We launched FUSILEV in August 2008 and we were able to benefit from broad utilization in community clinics and hospitals and recognized a dramatic increase in sales beginning in the second half of 2010 due to a shortage of generic leucovorin. We cannot predict the duration and extent of shortages of generic leucovorin supplies, which may occur from time to time, or the extent of the impact varying generic leucovorin supplies may ultimately have on FUSILEV utilization. In April of 2011, we received two FDA approvals for FUSILEV. The first FDA approval was for the use of FUSILEV in combination with 5-fluorouracil in the palliative treatment of patients with advanced metastatic colorectal cancer. The second FDA approval was for a “Ready-To-Use” formulation, or RTU, of FUSILEV. We are now actively engaged in marketing FUSILEV for use in advanced metastatic colorectal cancer.

We added FOLOTYN to our commercial drug portfolio with the acquisition of Allos Therapeutics, Inc., or Allos, in September 2012. FOLOTYN is a folate analogue metabolic inhibitor designed to accumulate preferentially in cancer cells. FOLOTYN targets the inhibition of dihydrofolate reductase, or DHFR, an enzyme critical in the folate pathway, thereby interfering with DNA and RNA synthesis and triggering cancer cell death. FOLOTYN can be delivered as a single agent, for which we currently have approval in the United States for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma, or PTCL, and has the potential to be used in combination therapy regimens. We believe that FOLOTYN’s unique mechanism of action offers us the ability to target the drug for development in a variety of hematological malignancies and solid tumor indications, and for autoimmune diseases as well. FOLOTYN has been available for commercial sale in the United States since October 2009.

41

For ZEVALIN, we continue to work on growing the ZEVALIN brand and are working to expand indications for use beyond follicular non-Hodkins lymphoma through additional trials. Effective April 2, 2012, with the acquisition of licensing rights from Bayer Pharma AG, we began the sales of ZEVALIN outside of the U.S. We have initiated and continue to build appropriate infrastructure and additional initiatives to facilitate broad customer reach and to address other market requirements, as appropriate, to expand utilization. We have formed a dedicated commercial organization comprised of highly experienced and motivated sales representatives, account managers, and a complement of other support marketing personnel to manage the sales and marketing of these drugs. In addition, our scientific department supports field activities through various MDs, PhDs and other medical science liaison personnel.

• Optimizing our development portfolio and maximizing the asset values of its components. While over the recent few years, we have evolved from a development-stage to a commercial-stage pharmaceutical company, we have maintained a highly focused development portfolio. Our strategy with regard to our development portfolio is to focus on late-stage drugs and to develop them safely and expeditiously to the point of regulatory approval. We plan to develop some of these drugs ourselves or with our subsidiaries and affiliates, or secure collaborations with third parties such that we are able to suitably monetize these assets. We have assembled a drug development infrastructure that is comprised of highly experienced and motivated MDs, PhDs, clinical research associates and a complement of other support personnel to develop these drugs. In April 2012, we announced that the single instillation Phase 3 clinical trials for apaziquone did not meet their primary endpoint, however, the pooled data from the studies did show a statistically significant treatment effect. A meeting with the FDA was held in December 2012 to discuss the results from these clinical trials. Based on the discussions with the FDA, we understand that the FDA can accept the NDA filing with the current Phase III data and will likely convene an Advisory Committee meeting. Further, based on discussions with the FDA, we have agreed to conduct one additional Phase III study following consultation with the FDA on its design.

With regard to our anti-cancer drug belinostat, a novel HDAC inhibitor, we have to date opened more than 100 international sites in the study of relapsed refractory peripheral T Cell Lymphoma. We completed enrollment in this trial in September 2011, announced top line results in December 2012 and expect to file a NDA in 2013.

We have several other compounds in earlier stages of development in our portfolio. Based upon a criteria-based portfolio review, we are in the process of streamlining our pipeline drugs, allowing for greater focus and integration of our development and commercial goals.

• Expanding our pipeline of development stage and commercial drugs through business development activities. It is our goal to identify new strategic opportunities that will create strong synergies with our currently marketed drugs and identify and pursue partnerships for out-licensing certain of our drugs in development. To this end, we will continue to explore strategic collaborations as these relate to drugs that are either in clinical trials or are currently on the market. We believe that such opportunistic collaborations will provide synergies with respect to how we deploy our internal resources. In this regard, we intend to identify and secure drugs that have significant growth potential either through enhanced marketing and sales efforts or through pursuit of additional clinical development. As a result of our business development activities, we announced in March 2013 that we had gained global development and commercialization rights to Ligand Pharmaceuticals’ Captisol-enabled^®, propylene glycol-free (PG-free) melphalan. Captisol-enabled melphalan is currently in a pivotal trial for use as a conditioning treatment prior to autologous stem cell transplant for patients with multiple myeloma. We also announced the acquisition of Talon Therapeutics, Inc. as of July 17, 2013. Through this acquisition, we gained worldwide rights to Marqibo^® (vincristine sulfate liposome injection) and Menadione Topical Lotion as described below.

• Managing our financial resources effectively. We remain committed to fiscal discipline, a policy which has allowed us to become well capitalized among our peers, despite a very challenging capital markets environment beginning in 2009 and continuing through 2013. This policy includes the pursuit of dilutive and non-dilutive funding options, prudent expense management, and the achievement of critical synergies within our operations in order to maintain a reasonable burn rate. Even with the continued build-up in operational infrastructure to facilitate the marketing of our three commercial drugs, we intend to be fiscally prudent in any expansion we undertake.

In terms of revenue generation, we rely on sales from currently marketed drugs and intend to pursue out-licensing of select pipeline drugs in select territories, as discussed above. When appropriate, we may pursue other sources of financing, including dilutive and non-dilutive financing alternatives. While we are currently focused on advancing our key drug development programs, we anticipate that we will make regular determinations as to which other programs, if any, to pursue and how much funding to direct to each program on an ongoing basis, based on clinical success and commercial potential, including termination of our existing development programs, especially if we do not expect value to be realized from continued development.

• Further enhancing the organizational structure to meet our corporate objectives. We have highly experienced staff in pharmaceutical operations, clinical development, regulatory and commercial functions who previously held positions at both small to mid-size biotech companies, as well as large pharmaceutical companies. We have strengthened the ranks of our management team, and will continue to pursue talent on an opportunistic basis. Finally, we remain committed to running a lean and efficient organization, while effectively leveraging our critical resources.

Financial Condition

Liquidity and Capital Resources

We remain dependent upon revenues from our three commercial drugs, specifically FUSILEV, FOLOTYN and ZEVALIN. Our long-term strategy is to continue to generate profits from the sale and licensing of our drug products.

While we believe that the approximately $127.9 million in cash, equivalents and investments, which includes long term marketable securities we had available on June 30, 2013 will allow us to fund our current planned operations for at least the next twelve to eighteen months, we may seek to obtain additional capital through the sale of debt or equity securities, if necessary, especially in conjunction with opportunistic acquisitions or licensing arrangements. We may be unable to obtain such additional capital when needed, or on terms favorable to us or our stockholders, if at all. If we raise additional funds by issuing equity securities, the percentage ownership of our stockholders will be reduced, stockholders may experience additional dilution or such equity securities may provide for rights, preferences or privileges senior to those of the holders of our common stock. If additional funds are raised through the issuance of debt securities, the terms of such securities may place restrictions on our ability to operate our business. If and when appropriate, just as we have done in the past, we may pursue non-dilutive financing alternatives as well. On September 5, 2012, we entered into a credit agreement with Bank of America and Wells Fargo Bank for a $75.0 million revolving line of credit, which was reduced to $50 million on July 16, 2013 in connection with our acquisition of Talon and which can be increased up to $100.0 million, subject to meeting certain customary conditions and obtaining commitments for such increase from the lenders (See Note 5). As of June 30, 2013, $50.0 million has been drawn down on the revolving line of credit and we were in compliance with all financial covenants.

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $3.4 million for the six months ended June 30, 2013, which includes a net loss in the period of $15.2 million adjusted for net non-cash credits of which $8.3 million of the $10.3 million of amortization of deferred revenue relates to the amendment of our collaboration agreement with Allergan, $6.0 million for a deferred income tax benefit offset by $10.8 million of depreciation and amortization, $5.7 million for stock-based compensation, $654,000 for foreign currency translation and $1.0 million for the provision for inventory obsolescence. These non-cash items were offset primarily by provisions for cash by a $39.7 million decrease in accounts receivable and a $11.5 million reduction in accounts payable and accrued obligations both of which were due to timing.

Net Cash Used in Investing Activities

Net cash used in investing activities of $3.1 million in the first six months of 2013 was due to the $3.0 million payment for the Melphalan license as described in Note 2 and the $127,000 purchase of property and equipment.

Net Cash (Used In) Provided By Financing Activities

Net cash (used in) provided by financing activities of $18.7 million for the six months ended June 30, 2013, primarily relates to the $25.0 million net repayment of the line of credit, $1.7 million purchase of treasury stock which was retired, the $410,000 repurchase of shares to satisfy minimum tax withholding for the vesting of restricted stock which was partially offset by $7.0 million in proceeds as a result of the Munidpharma contract amendment and $1.1 million in proceeds from the issuance of common stock as a result of the exercise of stock options.

FUSILEV revenues decreased for the three months ended June 30, 2013 compared to the same period in 2012, primarily due to a change in buying patterns of wholesalers, a lower net price and to a lesser extent a decrease in underlying demand. Government rebates and chargebacks as a percentage of gross sales increased by 7.1% as compared to the same period in 2012 which was driven primarily by a change in customer mix and to a lesser extent a refinement to our methodology to estimate rebate claims remaining in channel inventory. The Company does not expect that this level of government rebates and chargebacks will continue in the second half of the year. For the three months ended June 30, 2013, we reduced the FUSILEV product returns reserve by $646,000. Actual product returns for the three months ended June 30, 2013 were less than estimated returns which resulted in a reduction to our estimated return rate for products which may be eligible for return. ZEVALIN revenues for the three months ended June 30, 2013 were 24.5% less than the same period in 2012. Beginning in the second quarter of 2013, we terminated the Bayer transition services agreement and transitioned to a sales distribution model in Europe which we expect may negatively impact sales until this transition is complete.

Gross product revenues are reduced by estimated provisions for product returns, sales discounts and rebates, distribution and data fees, and estimates for chargeback’s established at the time revenues are recognized to arrive at product sales, net. Management considers various factors in determination of such provisions, which are described more in detail below. Product sales, net may vary from quarter to quarter based on customer mix and whether said customers are entitled to government mandated pricing which will be reflected in chargeback deductions from revenue.

During the three months ended June 30, 2013 and 2012, licensing revenues decreased $2.1 million due to the amendment of the Allergan agreement and reacquisition of licensing rights as described in Note 11 in the condensed consolidated financial statements.

Operating Costs and Expenses

Our operating costs and expenses are summarized in the following table:

	Three months ended June 30,						$ Change			% Change
	2013 (As Restated)			2012 (As Restated)
	($ in millions)
Operating costs and expenses:
Cost of product sales (excludes amortization of purchased intangibles)	$	7.3		$	11.6		$	(4.3	)		(37.1	)%
Selling, general and administrative		22.6			23.2			(0.6	)		(2.6	)%
Research and development		10.5			9.3			1.2			12.9	%
Amortization and impairment of purchased intangible assets		5.4			1.6			3.8			>100.0	%
Total operating costs and expenses	$	45.8		$	45.7		$	0.1			(0.2	)%
Other income (expense), net		(0.2	)		(1.5	)		1.3			(89.2	%)

Cost of Product Sales. The overall decrease in total cost of sales relates primarily to a decrease in product revenues which was partially offset by an increase of $58,000 for inventory reserves.

Selling, General and Administrative. Selling, general and administrative expenses decreased primarily due to:

• $900,000 increase in marketing expenses to promote FOLOTYN and to promote ZEVALIN outside the U.S.

• $1.0 million increase in professional fees which include legal fees for patents and trademarks, audit and tax services.

• $686,000 increase in legal and professional fees related to the Talon acquisition.

• $496,000 increase in commercial costs related to sales of ZEVALIN outside the U.S.

• $436,000 increase in legal and professional fees related to the shareholder lawsuit and patent litigation.

• $213,000 increase in computer software and services.

• $146,000 increase in rent and utilities due to the addition of the Japan, Colorado, New Jersey and Westlake Village (California) offices.

44

These increases were partially offset by:

• $3.2 million reduction in legal and professional fees related to the Allos tender offer and the Bayer agreement licensing rights to market ZEVALIN outside the U.S.

Research and Development. Research and development expenses increased as a result of the inclusion of Allos in the financial statements and is primarily due to:

• $1.8 million decrease in the reimbursement of expenses compared to the same period in 2012 primarily due to the amendment of the Allergan agreement in the first quarter of 2013.

• $539,000 increase in continuing medical education grants.

• $710,000 increase in consulting, compensation and associated benefits.

These increases were partially offset by:

• $2.4 million write off of deferred payment contingency as a result of the amendment to the Mundipharma agreement.

Amortization and Impairment of Purchased Intangibles. The non-cash amortization and impairment of purchased intangibles increased $3.8 million during the three months ended June 30, 2013, of which, $1.0 million is due to the impairment of the Allos intangible as a result of the Mundipharma contract amendment in May 2013. The remaining amount is due to the amortization of intangibles from the acquisition of ZEVALIN and the amortization of intangibles recognized from the acquisition of Allos.

Other Income (Expense), net. Other net income (expense), net increased primarily due to a $505,000 increase in interest expense in connection with the revolving line of credit which was partially offset by foreign currency gains. In the current economic environment, our principal investment objective is preservation of capital. Accordingly, for the foreseeable future we expect to earn minimal interest yields on our investments, until such time as the credit markets recover.

	($ in millions)
Benefit (provision) for income taxes	$	3.0	$	(3.2	)	$	6.2		>(100.0%	)

Benefit (Provision) for Income Taxes. As a result of our $12.7 million operating loss, we recorded a benefit for income taxes of $3.0 million for the three months ended June 30, 2013. For the three months ended June 30, 2012, we recorded a provision of $3.2 million on $21.5 million in operating profits. The tax provision for the three months ended June 30, 2012 is net of a benefit of $3.4 million which was realized as a result of the completion of a comprehensive R&D credit analysis for prior years and the related recognition of R&D credits.

We maintain a valuation allowance against our foreign net deferred tax assets as we continue to conclude it is not more likely than not that the foreign net deferred tax assets will be realized.

Our effective tax before discrete items was approximately 24% and 35% for the three months ended June 30, 2013 and 2012, respectively. The effective tax rate for the three months ended June 30, 2013 is below the statutory rate principally as a result of losses in foreign jurisdictions that were offset by a valuation allowance and deductions that are permanently disallowed for tax purposes.

Six months ended June 30, 2013 and 2012

Total Revenues. A summary of our total revenues is as follows:

	Six months ended June 30,				$ Change			% Change
	2013		2012
	($ in millions)
Product sales, net:
FUSILEV	$	24.7	$	107.8	$	(83.1	)		(77.1	)%

Total revenues	$	71.9	$	128.6	$	(56.7	)		(44.1	)%

FUSILEV revenues decreased for the six months ended June 30, 2013 compared to the same period in 2012, primarily due to a change in buying patterns of wholesalers, a lower net price partially offset by an increase in the underlying demand. Government rebates and chargebacks as a percentage of gross sales increased by 4.6% as compared to the same period in 2012 which was driven primarily by a change in customer mix and to a lesser extent a refinement to our methodology to estimate rebate claims remaining in channel inventory. The Company does not expect that this level of government rebates and chargebacks will continue in the second half of the year. For the six months ended June 30, 2013, we reduced the FUSILEV product returns reserve by $2.1 million. Actual product returns through June 30, 2013 were less than estimated returns which resulted in a reduction to our estimated sales return rate for products which may be eligible for return. ZEVALIN revenues for the six months ended June 30, 2013 were consistent with the same period in 2012. Beginning in the second quarter of 2013, we terminated the Bayer transition services agreement and transitioned to a sales distribution model in Europe which may negatively impact sales until this transition is complete.

Gross product revenues are reduced by estimated provisions for product returns, sales discounts and rebates, distribution and data fees, and estimates for chargeback’s established at the time revenues are recognized to arrive at product sales, net. Management considers various factors in determination of such provisions, which are described more in detail below. Product sales, net may vary from quarter to quarter based on customer mix and whether said customers are entitled to government mandated pricing which will be reflected in chargeback deductions from revenue.

During the six months ended June 30, 2013 and 2012, we also recognized approximately $10.3 million and $6.2 million of licensing revenues from the amortization of a $41.5 million upfront payment we received from Allergan in 2008, and $16.0 million upfront payment we received from Nippon Kayaku and Handok in the first quarter of 2010. Of the approximately $10.3 million recognized in 2013, we recognized $8.3 million of licensing revenues from Allergan in connection with the amendment of the agreement and reacquisition of licensing rights as described in Note 11 to the condensed consolidated financial statements.

Operating Costs and Expenses

Our operating costs and expenses are summarized in the following table:

	Six months ended June 30,						$ Change			% Change
	2013 (As Restated)			2012 (As Restated)
	($ in millions)

Other income (expense), net		(1.5	)		(1.4	)		(0.1	)		(8.2	%)

46

Cost of Product Sales. The overall decrease in total cost of sales relates primarily to a decrease in product revenues which was partially offset by an increase of $604,000 for excess inventory.

Selling, General and Administrative. Selling, general and administrative expenses increased as a result of the inclusion of Allos in the financial statements and is primarily due to:

• $1.1 million increase in compensation and associated benefits, which is mainly attributable to general and administrative expenses as a result of the addition of higher level management and the inclusion of personnel for Allos and personnel in Japan, and also includes a $363,000 increase in recruitment fees.

• $1.1 million increase in commercial costs related to sales of ZEVALIN outside the U.S.

• $1.5 million increase in marketing expenses to promote FOLOTYN.

• $1.7 million increase in professional fees which include legal for patents and trademarks, audit and tax services.

• $1.2 million increase in legal and professional fees related to the shareholder lawsuit and patent litigation.

• $686,000 increase in legal and professional fees related to the Talon acquisition.

• $518,000 increase in computer software and services.

• $374,000 increase in rent and utilities due to the addition of the Japan, Colorado, New Jersey and Westlake Village (California) offices.

These increases were partially offset by:

• $797,000 decrease in non-cash stock compensation expense primarily related to the management incentive plan expenses.

• $4.1 million reduction in legal and professional fees related to the Allos tender offer and the Bayer agreement licensing rights to market ZEVALIN outside the U.S.

We expect that sales and marketing activities, and therefore, selling, general and administrative expenses will remain approximately the same over the remainder of 2013.

Research and Development. Research and development expenses increased as a result of the inclusion of Allos in the financial statements and is primarily due to:

• $5.3 million decrease in the reimbursement of expenses compared to the same period in 2012 primarily due to the amendment of the Allergan agreement in the first quarter of 2013.

• $543,000 increase in continuing medical education grants

• $1.1 million increase in consulting, compensation and associated benefits

These increases were partially offset by:

• $2.4 million write off of deferred payment contingency as a result of the amendment to the Mundipharma agreement.

We expect research and development expenses to remain approximately the same for the remainder of the 2013, excluding the cost of in-licensing or acquisitions of additional drugs, if any.

Amortization and Impairment of Purchased Intangibles. The non-cash amortization and impairment of purchased intangibles increased $7.3 million during the six months ended June 30, 2013, of which $1.0 million is due to the impairment of the Allos intangible as a result of the Mundipharma contract amendment in May 2013. The remaining amount is due to the amortization of intangibles from the acquisition of ZEVALIN Ex. U.S. Rights and the amortization of intangibles recognized from the acquisition of Allos.

47

Other Income (Expense), net. Other net income (expense), net increased primarily due to a $928,000 increase in interest expense in connection with the revolving line of credit which was partially offset by a decrease in foreign currency losses. In the current economic environment, our principal investment objective is preservation of capital. Accordingly, for the foreseeable future we expect to earn minimal interest yields on our investments, until such time as the credit markets recover.

	Six months ended June 30,
	2013 (As Restated)		2012 (As Restated)		$ Change			% Change
	($ in millions)
Benefit for income taxes	$	5.3	$	19.9	$	(14.6	)		(73.4	%)

Benefit for Income Taxes. As a result of our year-to-date operating loss, we recorded a benefit for income taxes of $5.3 million for the six months ended June 30, 2013. For the six months ended June 30, 2012, we recorded a tax benefit of $19.9 million primarily as a result of the releasing $24 million of valuation allowance on domestic deferred tax assets as of January 1, 2012 as a discrete tax adjustment.

The release of the valuation allowance in 2012 was due to a change in judgment regarding the expected realization of our domestic deferred tax assets after considering positive and negative evidence which existed as of the quarter ended March 31, 2012. We maintain a valuation allowance against our foreign net deferred tax assets as we continue to conclude it is not more likely than not that the foreign net deferred tax assets will be realized.

Our effective tax rate before discrete items was approximately 24% and 21% for the six months ended June 30, 2013 and 2012, respectively. The effective tax rate for 2013 is below the statutory rate principally as a result of losses in foreign jurisdictions that were offset by a valuation allowance and deductions that are permanently disallowed for tax purposes. The lower effective tax rate in 2012 is principally due to the tax benefit realized as a result of the release of a portion of our domestic valuation allowance as of January 1, 2012 against 2012 earnings.

The American Taxpayer Relief Act of 2012 was enacted on January 2, 2013 and retroactively reinstated the U.S. R&D tax credit to January 1, 2012. During the six months ended June 30, 2013 we recognized $0.4 million as a discrete tax benefit due to the retroactive reinstatement of the U.S. R&D tax credit for 2012.

Nature of Each Accrual That Reduces Gross Revenue to Net Revenue

Provisions for government rebates, commercial rebates, chargebacks, data and distribution product returns, sales discounts and rebates and estimates for chargebacks are established as a reduction of product sales revenue at the time revenues are recognized. We consider various factors in determining such provisions. Such estimated amounts are deducted from our gross sales to determine our net revenues. Provisions for rebates, chargebacks, data and distribution fees, GPO fees, prompt pay discount and returns are classified as part of our accrued obligations. Changes in our estimates, if any, are recorded in the statements of operations in the period the change is determined. If we materially over or under estimate the amount, there could be a material impact on our condensed consolidated financial statements.

For the six months ended June 30, 2013 and 2012, the following is a roll forward of the reductions to revenue:

	Rebates and Chargebacks			Data and Distribution and GPO Fees			Prompt Pay Discount			Returns			Total
				($ in ‘000’s)
Period ended June 30, 2013:
Balances at beginning of the period	$	26,176		$	14,149		$	1,451		$	5,056		$	46,832
Add: provisions (recovery):		31,083			10,046			105			(2,299	)		38,935
Less: Credits or actual allowances:		(27,204	)		(15,374	)		(1,221	)		(107	)		(43,906	)
Balances at the close of the period	$	30,055		$	8,821		$	335		$	2,650		$	41,861
Period ended June 30, 2012:
Balances at beginning of period	$	9,064		$	9,808		$	992		$	4,000		$	23,864

Balances at the close of the period	$	26,582		$	13,663		$	1,178		$	3,500		$	44,923

Amounts recorded as reductions to revenue on our condensed consolidated balance sheets for 2013 and 2012 are reflected in the table above. The basis and methods of estimating these reductions, used by management, are more fully described in “Critical Accounting Policies, Estimates and Assumptions” in our Annual Report on Form 10-K for the year ended December 31, 2012.

Off-Balance Sheet Arrangements

Since inception, we have not engaged in material off-balance sheet activities, including the use of structured finance, special purpose entities or variable interest entities.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The accounting policies that reflect our more significant estimates, judgments and assumptions and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

• Revenue recognition

• Fair value of acquired assets

• Research and development

• Fair value measurements

• Amortization and impairment of intangible assets

• Share-based compensation

49

During the three months ended June 30, 2013, there were no significant changes in our critical accounting policies and estimates. Please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012 for a more complete discussion of our critical accounting policies and estimates.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, our operations are exposed to risks associated with fluctuations in interest rates and foreign currency exchange rates.

The primary objective of our investment activities is to preserve capital, while at the same time maximizing yields without significantly increasing risk. We do not utilize hedging contracts or similar instruments.

We are exposed to certain market risks. Our primary exposures relate to (1) interest rate risk on our investment portfolio, (2) credit risk of the companies’ bonds in which we invest, (3) interest rate risk on borrowings under the Credit Facility, (4) general credit market risks as have existed since late 2007 and (5) the financial viability of the institutions which hold our capital and through which we have invested our funds. We manage such risks on our investment portfolio by investing in highly liquid, highly rated instruments and not investing in long-term maturity instruments.

In response to the dislocation in the credit markets since the latter part of 2007, in early 2008 we converted substantially all of our investments, including all of our market auction debt securities, into highly liquid and safe instruments. Our investments, as of June 30, 2013 and 2012, were primarily in money market accounts, short-term corporate bonds, certificates of deposit, U.S. Treasury bills and U.S. Treasury-backed securities. We believe the financial institutions through which we have invested our funds are strong and well capitalized and our instruments are held in accounts segregated from the assets of the institutions. However, due to the current extremely volatile financial and credit markets and liquidity crunch faced by many banking institutions, the financial viability of these institutions, and the safety and liquidity of our funds are being constantly monitored. Because of our ability to generally redeem these investments at par on short notice and without penalty, we believe that changes in interest rates would have an immaterial effect on the fair value of these investments. If a 10% change in interest rates were to have occurred on June 30, 2013 or 2012, any decline in the fair value of our investments or increase in our obligations under our credit agreement (described below) would not be material in the context of our condensed consolidated financial statements. In addition, we are exposed to certain market risks associated with credit ratings of corporations whose corporate bonds we may purchase from time to time. If these companies were to experience a significant detrimental change in their credit ratings, the fair market value of such corporate bonds may significantly decrease. If these companies were to default on these corporate bonds, we may lose part or all of our principal. We believe that we effectively manage this market risk by diversifying our investments and investing in highly rated securities.

In addition, we are exposed to foreign currency exchange rate fluctuations relating to payments we make to vendors, suppliers and license partners using foreign currencies.

In connection with our acquisition of Allos Therapeutics, Inc. in September 2012, we entered into a credit agreement with Bank of America, N.A. as the administrative agent and Wells Fargo Bank, N.A. as an initial lender for a $75 million revolving line of credit. This line of credit was reduced to $50 million on July 16, 2013 in connection with our acquisition of Talon Therapeutics. Inc. and can be increased to $100 million, subject to meeting certain customary conditions and obtaining commitments for such increase from our lenders. The credit agreement contains certain financial covenants and expires on September 5, 2014.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer (“CEO”) and chief financial officer (“CFO”) evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2013. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.

50

At the time that our Annual Report on Form 10-K for the year ended December 31, 2012 was filed on February 28, 2013, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2012. At the time that our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 was filed on May 9, 2013, our CEO and CFO concluded that our disclosure controls and procedures were effective as of March 31, 2013. At the time that our Quarterly Report on Form 10-Q for the quarter ended June 30, 2013 was filed on August 9, 2013, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 30, 2013. Subsequent to these evaluations, our CEO and CFO concluded that our disclosure controls and procedures were not effective as of December 31, 2012, March 31, 2013, and June 30, 2013, and continue to not be effective as of September 30, 2013 because of a material weakness in our internal control over financial reporting, as described below.

Changes in Internal Control Over Financial Reporting

While preparing our financial statements for the three and nine months ended September 30, 2013, we determined that our June 30, 2013 and December 31, 2012 Condensed Consolidated Balance Sheets, included within our respective Form 10-Q and Form 10-K filings presented a $7.7 million and $7.2 million overstatement, respectively, within “accounts payable and other accrued obligations.”

The components of the “accounts payable and other accrued obligations” overstatement comprise excess accruals that correspond with (i) research and development and sales and marketing activities that accumulated over multiple reporting periods from January 1, 2007 through June 30, 2013, and (ii) excess liabilities that were recorded as part of our business combination accounting for the 2009 acquisition of RIT Oncology, LLC that did not require settlement, and were not identified as such within a timely manner.

We have concluded that, when aggregated as of March 31, 2013, June 30, 3013, and December 31, 2012, these deficiencies represent a “material weakness” in our internal controls over financial reporting, and accordingly, our internal control over financial reporting was ineffective at each of these dates.

A material weakness is a deficiency, or a combination of deficiencies, in internal controls over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis. We have developed, and are currently implementing, a remediation plan for this material weakness. We will continue to execute our remediation plan, which includes, among other things, hiring additional experienced accounting personnel and expanding training for our accounting personnel. The successful remediation of this material weakness will require review and evidence of the effectiveness of the related internal controls as part of our next annual assessment of our internal controls over financial reporting as of December 31, 2013.

As we continue to evaluate and work to enhance internal control over financial reporting, we may determine that additional measures should be taken to address these or other control deficiencies, and/or that we should modify the remediation plan described above.

Notwithstanding our material weakness, we have concluded that the financial statements, and other financial information included in this Quarterly Report on Form 10-Q, fairly present in all material respects our financial condition, results of operations and cash flows as of, and for, the periods presented.

Except as disclosed above, no change in our internal control over financial reporting occurred during the fiscal quarter ended June 30, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations of the Effectiveness of Internal Controls

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the internal control system are met. Because of inherent limitations in any control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. We are continuously seeking to improve the efficiency and effectiveness of our operations and of our internal controls.

Scott, and Joseph Kenneth Keller. The alleged class period is August 8, 2012 to March 12, 2013. The lawsuits allege a violation of Section 10(b) of the Securities Exchange Act of 1934 against all defendants and control person liability, as a violation of Section 20(b) of the Securities Exchange Act of 1934, against the individual defendants. The claims purportedly stem from the Company’s March 12, 2013 press release, in which it announced that it anticipated a change in ordering patterns of FUSILEV. The complaints allege that, as a result of the March 12, 2013 press release, the Company’s stock price declined. The complaints further allege that during the putative class period certain defendants made misleadingly optimistic statements about FUSILEV sales, which inflated the trading price of Company stock. The lawsuits seek relief in the form of monetary damages, costs and fees, and any other equitable or injunctive relief that the court deems appropriate. The putative class action cases have been consolidated. Plaintiffs’ counsel have filed motions for the appointment of a lead plaintiff and lead plaintiff’s legal counsel. The motions are briefed. Plaintiffs’ counsel represent that an amended complaint will be filed following the Court’s decision on lead plaintiff and lead plaintiffs’ legal counsel.

(Filed May 28, 2013 in United States District Court, District of Nevada; Case Number 2:2013-cv-00942-APG-PAL). These derivative complaints are brought by the respective purported shareholders on behalf of nominal plaintiff Spectrum Pharmaceuticals, Inc. against defendants Krishan K. Arora, Gilles Gagnon, Anton Gueth, Joseph Kenneth Keller, Stuart M Krassner, Luigi Lenaz, Anthony E. Maida, Brett L. Scott and Dr. Rajesh C. Shrotriya. The Fik and Watkins lawsuits allege six counts against all defendants: breach of fiduciary duty for disseminating false and misleading information; breach of fiduciary duty for failing to properly oversee and manage the company; unjust enrichment; abuse of control; gross mismanagement; and waste of corporate assets. The Fik and Watkins lawsuits also allege a seventh count for breach of fiduciary duties for insider selling and misappropriation of information against defendants Dr. Raj Shrotriya, Brett Scott, and Anthony Maida. The Muenchhagen lawsuit alleges five counts against all defendants: breach of fiduciary duty for disseminating false and misleading information; breach of fiduciary duty for failing to properly oversee and manage the company; abuse of control; gross mismanagement; and waste of corporate assets. The Muenchhagen lawsuit also alleges two counts against defendants Dr. Raj Shrotriya, Brett Scott, and Anthony Maida for unjust enrichment and for breach of fiduciary duties for insider selling and misappropriation of information. These substantially identical complaints allege that defendants knew or should have known that the Company’s statements about future FUSILEV sales were misleadingly optimistic and that these statements inflated the trading price of Company stock. The complaints allege that, as a result of the March 12, 2013 press release, the Company’s stock price declined. The complaints seek compensatory damages, corporate governance reforms, restitution and disgorgement of defendants’ alleged profits, and costs and fees. The Fik and Watkins cases have been consolidated and stayed. The parties have submitted a notice to consolidate and stay the Muenchhagen case.

Hardik Kakadia v. Rajesh C. Shrotriya, et al. (Filed April 23, 2013 in the Eighth Judicial District Court of the State of Nevada in and for Clark County; Case Number A-13-680643-B); and Joel Besner v. Rajesh C. Shrotriya, et al. (Filed May 31, 2013 in the Eighth Judicial District Court of the State of Nevada in and for Clark County; Case Number A-13-682668-C). These derivative complaints are brought by the respective purported shareholders on behalf of nominal plaintiff Spectrum Pharmaceuticals, Inc. against defendants Krishan K. Arora, Gilles Gagnon, Anton Gueth, Joseph Kenneth Keller, Stuart M Krassner, Luigi Lenaz, Anthony E. Maida, Brett L. Scott and Dr. Rajesh C. Shrotriya. The Kakadia lawsuit alleges three counts against all defendants: breach of fiduciary duty; waste of corporate assets; and unjust enrichment. The Besner lawsuit alleges five counts against all defendants: breach of fiduciary duty for disseminating false and misleading information; breach of fiduciary duty for failing to properly oversee and manage the company; abuse of control; gross mismanagement; and waste of corporate assets. The Besner lawsuit also alleges two counts against defendants Dr. Raj Shrotriya, Brett Scott, and Anthony Maida for unjust enrichment and for breach of fiduciary duties for insider selling and misappropriation of information. The complaints similarly allege that defendants knew or should have known that the Company’s statements about future FUSILEV sales were misleadingly optimistic and that these statements inflated the trading price of Company stock. The complaints allege that, as a result of the March 12, 2013 press release, the Company’s stock price declined. The complaints seek compensatory damages, corporate governance reforms, restitution and disgorgement of defendants’ alleged profits, equitable and/or injunctive relief, and costs and fees. The cases have been consolidated and stayed.

SEC Subpoena

On April 1, 2013, the Company received a subpoena from the Securities and Exchange Commission (the “SEC”) for documents pursuant to a formal order of investigation. The subpoena followed the Company’s March 12, 2013 announcement that it anticipated a change in ordering patterns of FUSILEV. The Company is cooperating with the SEC investigation. The Company cannot predict when the SEC will conclude its investigation or the outcome of the investigation.

We are involved with various legal matters arising in the ordinary course of business. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our condensed consolidated results of operations, cash flows or financial condition.

ITEM 1A. RISK FACTORS

The risks described in Part I, Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, could materially and adversely affect our business, financial condition and results of operations. These risk factors do not identify all of the risks that we face. Our business, financial condition and results of operations could also be affected by factors that are not presently known to us or that we currently consider to be immaterial. Except for the below, there have been no material changes to the “Risk Factors” section included in our 2012 Annual Report:

We have identified a material weakness in our internal control over financial reporting which existed as of December 31, 2012, and has not been adequately remediated as of March 31, 2013, June 30, 2013 and September 30, 2013. If we fail to properly remediate this or any future weaknesses or deficiencies or maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’ views of us could be harmed.

While preparing our financial statements for the three and nine months ended September 30, 2013, we have determined that we have a material weakness in our internal control over financial reporting which also existed as of December 31, 2012. The financial misstatements resulting from our material weakness resulted in a restatement of our Condensed Consolidated Financial Statements contained herein. See Item 4, Controls and Procedures for a complete discussion of this material weakness in our internal control over financial reporting.

Although we are undertaking steps to address this material weakness, the existence of a material weakness is an indication that there is more than a remote likelihood that a material misstatement of our financial statements will not be prevented or detected in the current or any future period. There can be no assurance that we will be able to fully implement our plans and controls, as described in Item 4, to address this material weakness, or that the plans and controls, if implemented, will be successful in fully remediating this material weakness. In addition, we may in the future identify further material weaknesses in our internal control over financial reporting that we have not discovered to date. If we fail to successfully remediate the identified material weakness, or we identify further material weaknesses in our internal controls, the market’s confidence in our financial statements could decline and the market price of our common stock could be adversely impacted.

Commitments and Contingencies

6 Months Ended

Jun. 30, 2013

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

11. Commitments and Contingencies

Facility Lease

We sublease our principal executive office in Henderson, Nevada under a non cancelable operating lease expiring April 30, 2014. We also lease our research and development facility in Irvine, California under a non cancelable operating lease expiring June 30, 2016. Each lease agreement contains certain scheduled rent increases which are accounted for on a straight-line basis.

As part of our Irvine facility lease renewal in 2009, the landlord agreed to contribute up to approximately $1.5 million toward the cost of tenant improvements. The tenant improvements were completed in 2010 at an aggregate cost of approximately $1.4 million, of which, $451,000 is being financed. This landlord contribution is being amortized on a straight-line basis over the term of the lease as a reduction to rent expense. We also lease small administrative offices in Colorado, New Jersey, Westlake Village (California), Tokyo, Japan and Mumbai, India.

Licensing Agreements

We are developing almost all of our drug candidates pursuant to license agreements that provide us with rights in certain territories, among other things, to develop, sublicense, manufacture and sell the drugs. We are generally required to use commercially reasonable efforts to develop the drugs, and are generally responsible for all development, patent filing and maintenance, sales and marketing and liability insurance costs, and are generally contingently obligated to make milestone payments to the licensors if we successfully reach development and regulatory milestones specified in the license agreements. In addition, we are obligated to pay royalties and, in some cases, milestone payments based on net sales, if any, after marketing approval is obtained from regulatory authorities.

The potential contingent development and regulatory milestone obligations under all of our licensing agreements are generally tied to progress through the various regulatory authorities’ approval process, which approval significantly depends on positive clinical trial results. The following items are typical of such milestone events: conclusion of Phase 2 or commencement of Phase 3 clinical trials; filing of new drug applications in each of the United States, Europe and Japan; and approvals from each of the regulatory agencies in those jurisdictions.

ZEVALIN licensing and development in the United States

In December 2008, we acquired rights to commercialize and develop ZEVALIN in the United States as the result of a transaction with Cell Therapeutics, Inc. (“CTI”). Pursuant to the transfer of the ZEVALIN assets from CTI to a joint venture, RIT Oncology LLC (“RIT”), in December 2008, RIT assumed certain agreements with various third parties related to ZEVALIN intellectual property. These currently effective agreements relate to the manufacture, use and sale of ZEVALIN in the United States and include (i) a license from Biogen, Idec, Inc. (“Biogen”) (ii) a license-back to Biogen for limited uses including fulfillment of a supply obligation to CTI, (iii) a sublicense from Biogen to certain ZEVALIN patents held by Genentech, Inc., (iv) a sublicense from Biogen to certain ZEVALIN patents held by GlaxoSmithKline and Glaxo Group Limited, and (v) a sublicense from Biogen to certain ZEVALIN patents held by Corixa Corporation, Coulter Pharmaceutical, Inc., The Regents of the University of Michigan and GlaxoSmithKline.

In accordance with the terms of such agreements, RIT is required to meet specified payment obligations including a commercial milestone payment to Corixa Corporation of $5.0 million based on ZEVALIN sales in the United States, which has not been met as of June 30, 2013, as well as U.S. net sales-based royalties of low to mid-single digits to Genentech, Inc. and mid-single digits to Corixa Corporation. Such agreements generally continue until the last to expire of the licensed patents unless earlier terminated in accordance with the terms of the agreement for bankruptcy or material breaches that remain uncured. The patents that are subject to the agreements expire between 2014 and 2019.

Asset Purchase Agreement between CTI and Biogen, ZEVALIN U.S.

In connection with the joint venture arrangement with CTI, we entered into an amendment to the original asset purchase agreement between CTI and Biogen, referred to as the CTI/Biogen Agreement, modifying future milestone payments. Pursuant to the terms of the agreement, as amended, (i) upon the achievement of the specified FDA approval milestone, which was achieved in 2009, RIT (as successor to CTI) paid Biogen an additional amount of $5.5 million, (ii) RIT may be required to make an additional $10.0 million milestone payment upon the achievement of an additional FDA approval milestone, and (iii) RIT is required to make yearly royalty payments determined as a mid-single to mid-teen digits percentage of yearly net sales for the preceding year, increasing with the passage of time, with specific rates subject to confidential treatment pursuant to an order by the SEC. The agreement has an indefinite term and is no longer subject to termination; provided, however, that the royalty obligations automatically terminate upon the latest to occur of expiration of the subject patents, the sale by a third party of a biosimilar product in the U.S. or December 31, 2015. CTI’s rights and obligations, including its payment obligations to Biogen for royalties on net sales of ZEVALIN and an additional regulatory milestone payment, under both the CTI/Biogen Agreement and the amendment were assigned to and assumed by RIT in connection with the closing of the joint venture transaction.

Supply Agreement between Biogen and CTI, ZEVALIN U.S.

In connection with the joint venture arrangement with CTI, we entered into an amendment to the original supply agreement between Biogen and CTI, referred to as the CTI/Biogen Supply Agreement, modifying certain of the pricing and manufacturing technology transfer terms contained in the CTI/Biogen Supply Agreement and also providing that the term of the agreement may be shortened in some instances in the event of a mid-term manufacturing technology transfer. There are no milestone or royalty payments required pursuant to this agreement. The term of the agreement is until the manufacturing technology transfer is complete. Either party may generally terminate this agreement due to a bankruptcy of the other party or due to such other party’s material noncompliance with the agreement or certain other related agreements. CTI’s rights and obligations, including its payment obligations to Biogen, under both the CTI/Biogen Supply Agreement and the amendment were assigned to and assumed by RIT in connection with the closing of the joint venture transaction.

License and Asset Purchase Agreement with Bayer Pharma, ZEVALIN Ex—U.S.

On April 1, 2012, through a subsidiary, Spectrum Pharmaceuticals Cayman, L.P., we completed the acquisition of licensing rights to market ZEVALIN outside of the U.S., referred to as the ZEVALIN Ex-US Rights, from Bayer Pharma AG, or Bayer. Pursuant to the terms of the agreement, Spectrum acquired all rights including marketing, selling, intellectual property and access to existing inventory of ZEVALIN from Bayer. We currently market ZEVALIN in the U.S. and this agreement expands our commercial efforts to the rest of the world. ZEVALIN is currently approved in more than 40 countries outside the U.S. for the treatment of B-cell non-Hodgkin lymphoma, including countries in Europe, Latin America and Asia. In consideration for the rights granted under the agreement, concurrent with the closing, Spectrum paid Bayer a one-time fee of Euro 19 million or approximately USD $25.4 million, and will pay Bayer royalties based on a mid-teen digits percentage of net sales of the licensed products in all territories worldwide except the U.S., with specific rates subject to confidential treatment pursuant to an order by the SEC. Under the agreement, we also acquired access to existing inventory of ZEVALIN and concurrent with the closing, entered into certain ancillary agreements including but not limited to a transition services agreement to transition the business. Unless earlier terminated, the term of the agreement continues until the expiration of our royalty payment obligations which, in turn, run until the last-to-expire patent covering the sale of a licensed product in the relevant country or fifteen (15) years from the date of first commercial sale of the licensed product in such country, whichever is longer. This agreement may be terminated in the event of a material default, which is defined to include: (i) our failure to timely pay royalty payments under this agreement or payments under certain related agreements; (ii) our insolvency; and (iii) our breach and the resulting termination of an Amended and Restated License Agreement between Biogen and Bayer, dated as of January 16, 2012.

Amended and Restated License Agreement with Merck & Cie AG, FUSILEV.

In May 2006, we amended and restated a license agreement with Merck & Cie AG, a Swiss corporation, which we assumed in connection with the acquisition of the assets of Targent. Pursuant to the license agreement with Merck & Cie, we obtained the exclusive license to use regulatory filings related to FUSILEV and a non-exclusive license under certain patents and know-how related to FUSILEV to develop, make, and have made, use, sell and have sold FUSILEV in the field of oncology in North America. In addition, we have the right of first opportunity to negotiate an exclusive license to manufacture, have manufactured, use and sell FUSILEV products outside the field of oncology in North America. Also, under the terms of the license agreement, we paid Merck & Cie $100,000 for the achievement of FDA approval of an injectable form of FUSILEV. Merck & Cie is also eligible to receive a $200,000 payment upon achievement of FDA approval of an oral form of FUSILEV, in addition to royalties in the mid-single digits based on a percentage of net sales. The term of the license agreement is determined on a product-by-product and country-by-country basis until royalties are no longer owed under the license agreement. The license agreement expires in its entirety after the date that we no longer owe any royalties to Merck & Cie. We have the unilateral right to terminate the license agreement, in its entirety or on a product-by-product or country-by-country basis, at any time for any reason and either party may terminate the license agreement due to material breach of the terms of the license agreement by or insolvency of the other party.

Asset Purchase Agreement with Targent, Inc., FUSILEV

In March 2006, we entered into an Asset Purchase Agreement with Targent, Inc. (“Targent”). As part of the consideration for the purchase of certain assets, we agreed to pay milestone payments to Targent upon the achievement of certain regulatory events as well as for certain sales levels for FUSILEV within a calendar year. In connection with the achievement of the FDA approval milestone in April 2011, we issued an aggregate of 733,715 shares of common stock to certain of Targent’s stockholders, as directed by Targent. We capitalized $6.3 million associated with this milestone as intangible assets during 2011 which is being amortized over the estimated useful life of 8.7 years.

In addition, in connection with the achievement of the first sales milestone of $40 million in May 2011 we issued 577,367 shares of common stock to certain of Targent’s stockholders (which was equivalent value to approximately $5 million in cash), as directed by Targent. In September 2011, we achieved the second and final sales milestone of $100 million and paid $5 million in cash for an aggregate with the first sales milestone of $10.0 million. We capitalized the $10.0 million associated with these milestones as intangible assets. These intangible assets are being amortized over the estimated useful life of 8.6 years. As of December 2011, we have met all of the contractual milestones related to FUSILEV.

License Agreement with Sloan-Kettering Institute, SRI International and Southern Research Institute, FOLOTYN

In December 2002, Allos entered into the FOLOTYN License Agreement with Sloan-Kettering Institute for Cancer Research, SRI International and Southern Research Institute. As a result of Allos becoming our wholly owned subsidiary effective September 5, 2012, on a consolidated basis we are bound by the FOLOTYN License Agreement under which we obtained exclusive worldwide rights to a portfolio of patents and patent applications related to FOLOTYN and its uses. Under the terms of the FOLOTYN License Agreement, we are required to fund all development programs and will have sole responsibility for all commercialization activities. In addition, we pay the licensors royalties based on worldwide graduated annual levels of net sales of FOLOTYN, net of actual rebates, chargebacks and returns, or distributor sales, which may be different than our net product revenue recognized in accordance with U.S. generally accepted accounting principles, or GAAP, or sublicense revenues arising from sublicensing the product, if and when such sales or sublicenses occur. For purposes of the FOLOTYN License Agreement, annual worldwide sales consists of our distributor sales and annual net sales of FOLOTYN in the Mundipharma Territories, as reported to us under the Mundipharma Collaboration Agreement, if and when such sales occur in the Mundipharma Territories. Royalties are 8% of annual worldwide sales up to $150.0 million; 9% of annual worldwide sales of $150.0 million through $300.0 million; and 11% of annual worldwide sales in excess of $300.0 million. For the six months ended June 30, 2013, our royalties were 8% of our net distributor sales. As of June 30, 2013, accrued royalties were $1.2 million and are included in accounts payable and accrued obligations on the consolidated balance sheet.

Exclusive Development and Commercialization Collaboration Agreement with Allergan, apaziquone

In October 2008, we signed an exclusive development and commercialization collaboration agreement with Allergan for apaziquone. Pursuant to the terms of the agreement, Allergan paid us an up-front non-refundable $41.5 million at closing and is obligated to make additional payments based on the achievement of certain development, regulatory and commercialization milestones. Under the terms of the original agreement, we were entitled to payment of $57.5 million and $245 million upon achievement of certain regulatory and commercialization milestones, respectively, of which $1.5 million has been achieved following completion of enrollment in clinical trials, per the terms of the license, development, supply and distribution agreement. Also, Allergan agreed to pay us tiered royalties starting in the mid-teens based on a percentage of net sales of apaziquone outside of the U.S. and Asia, which specific rates are subject to confidential treatment pursuant to an order by the SEC.

On January 29, 2013, we entered into a second amendment to the license, development, supply and distribution agreement with Allergan to amend the agreement and reacquire the rights originally licensed to Allergan in the U.S. Europe and other territories in exchange for a tiered single digit royalty on certain products containing Apaziquone, and relieved Allergan of its obligations for development, commercialization and other activities. As a result of the second amendment to the agreement with Allergan, Allergan has no remaining obligations to the Company and Spectrum has no remaining performance obligations to Allergan. However, the Company is obligated to pay Allergan a tiered single-digit royalty not to exceed mid-single digits based upon the net sales, when and if earned, of certain products containing Apaziquone in specified territories. Additionally, the Company is obligated to pay any royalties or other payments due to licensors of the Licensed Intellectual Property (as defined in the agreement) as well as to provide indemnification of Allergan for claims arising from the manufacture, development or commercialization of pharmaceutical products containing Apaziquone by the Company. We recognized $8.3 million, the remaining balance of deferred revenue related to this agreement, during the three months ended March 31, 2013 and six months ended June 30, 2013.

Collaboration Agreement with Nippon Kayaku Co. LTD., apaziquone

In November 2009, we entered into a collaboration agreement with Nippon Kayaku Co., LTD. (“Nippon Kayaku”) for the development and commercialization of apaziquone in Asia, except North and South Korea (the “Nippon Kayaku Territory”). In addition, Nippon Kayaku received exclusive rights to apaziquone for the treatment of non muscle invasive bladder cancer in Asia (other than North and South Korea), including Japan and China. Nippon Kayaku will conduct apaziquone clinical trials in the Nippon Kayaku Territory pursuant to a development plan. Further, Nippon Kayaku will be responsible for all expenses relating to the development and commercialization of apaziquone in the Nippon Kayaku Territory.

Pursuant to the terms of this agreement, Nippon Kayaku paid Spectrum an upfront fee of $15 million and is obligated to make additional payments based on the achievement of certain development, regulatory and commercialization milestones. Under the terms of the agreement, we are entitled to payment of $10 million and $126 million upon achievement of certain regulatory and commercialization milestones, respectively. Also, Nippon Kayaku has agreed to pay Spectrum royalties based on a percentage of net sales of the subject products in the defined territory in the mid-teen digits, which specific royalty rates are subject to confidential treatment pursuant to an order by the SEC. The agreement will remain in effect, on a country-by-country basis, until the expiration of the obligation of Nippon Kayaku to pay royalties on sales of the subject products in such country. Nippon Kayaku may terminate the agreement at its election upon nine months notice to Spectrum. Additionally, either party may terminate the agreement for an uncured material breach by the other party.

Our license agreement with Nippon Kayaku provides for payments to us upon the achievement of development milestones, such as the completion of clinical trials or regulatory submissions, approvals by health authorities, and commercial launches of drug candidates. Given the challenges inherent in developing and obtaining approval for drug products and in achieving commercial launches, there was substantial uncertainty whether any such milestones would be achieved at the time of execution of such license agreement. In addition, we continue to evaluate whether the development milestones, none of which have been achieved to date, meet the remaining criteria to be considered substantive. As a result of our analysis, we consider our development milestones under the Nippon Kayaku license agreement to be substantive and, accordingly, we expect to recognize as revenue future payments received from such milestones only if and as each milestone is achieved.

Licensing and Collaboration Agreement with TopoTarget, belinostat

In February 2010, we entered into a licensing and collaboration agreement with TopoTarget, for the development and commercialization of belinostat, pursuant to which we agreed to collaboration for the development and commercialization of belinostat. The agreement provides that we have the exclusive right to make, develop and commercialize belinostat in North America and India, with an option for China. The agreement also grants TopoTarget a co-promote option if and only if we do not maintain a minimum number (subject to adjustment for certain events outside of our control) of field personnel (as defined in the agreement) for a certain number of years post-approval of the PTCL indication.

Under the terms of the agreement, all development, including studies, will be conducted under a joint development plan and in accordance with a mutually agreed upon target product profile provided that we have final decision-making authority for all developmental activities in North America and India (and China upon exercise of the option for China) and TopoTarget has final decision-making authority for all developmental activities in all other jurisdictions. We have agreed to assume all responsibility for and future costs of the ongoing registrational PTCL trial. We and TopoTarget will conduct future planned clinical trials pursuant to the joint development plan, of which we will fund 70% of the development costs and TopoTarget will fund 30% of the development costs. We and TopoTarget will each pay 50% of the costs for chemical, pharmaceutical and other process development related to the manufacturing of the product that are incurred with a mutually agreed upon budget in the joint development plan. TopoTarget is responsible for supplying us with both clinical and commercial product.

Pursuant to the terms of this agreement, Spectrum paid TopoTarget an upfront fee of $30 million. In addition, on the successful achievement of certain development, regulatory and sales milestones, none of which have been achieved to date, Spectrum is obligated to issue one million (1,000,000) shares of its common stock (subject to certain resale conditions) and pay TopoTarget up to $313 million. Also, Spectrum will pay TopoTarget royalties in the mid-teen digits based on net sales of the subject product in the defined territory, which specific royalty rates are subject to confidential treatment pursuant to an order by the SEC. None of such royalties have been earned or paid since inception of the agreement.

The agreement will continue until the expiration of the last royalty payment period in the last country in the defined territory with certain provisions surviving, unless earlier terminated in accordance with its terms. Spectrum may terminate the agreement at its election upon one hundred eighty (180) days notice to TopoTarget. Generally, Spectrum may also terminate immediately upon a prohibition on the use of the subject product or clinical hold by the FDA. TopoTarget may also terminate immediately in the event of a challenge (without TopoTarget’s consent) by Spectrum of the patents that cover the product. Either party may terminate the agreement upon a bankruptcy by the other party, or in the event of an uncured material breach by the other party.

Co-Development and Commercialization Agreement with Hanmi Pharmaceutical Company, SPI-2012

In late January 2012, we entered into a co-development and commercialization agreement with Hanmi Pharmaceutical Company, (“Hanmi”), for SPI-2012, formerly known as “LAPS-GCSF”, a drug for the treatment of chemotherapy induced neutropenia based on Hanmi’s proprietary LAPSCOVERY™ Technology. In consideration for the rights granted to us under the co-development and commercialization agreement with Hanmi, we paid Hanmi a fee which is included in research and development expense in the accompanying condensed consolidated financial statements because the technology has not yet achieved regulatory approval. We expect to initiate Phase 2 trials in collaboration with Hanmi in 2013. Under the terms of the agreement, we will share the costs and expenses of the study although we will have primary responsibility for them. If SPI-2012 is ultimately commercialized by us, we will have worldwide rights except for Korea, China and Japan upon payment of fees and milestone payments related to further development, regulatory approvals and sales targets.

Service Agreements

In connection with the research and development of our drug products, we have entered into contracts with numerous third party service providers, such as radio-pharmacies, distributors, clinical trial centers, clinical research organizations, data monitoring centers, and with drug formulation, development and testing laboratories. The financial terms of these agreements are varied and generally obligate us to pay in stages, depending on achievement of certain events specified in the agreements, such as contract execution, reservation of service or production capacity, actual performance of service, or the successful accrual and dosing of patients.

At each period end, we accrue for all costs of goods and services received, with such accruals based on factors such as estimates of work performed, patient enrollment, completion of patient studies and other events. We are in a position to accelerate, slow-down or discontinue any or all of the projects that we are working on at any given point in time. Should we decide to discontinue and/or slow-down the work on any project, the associated costs for those projects would be limited to the extent of the work completed. Generally, we are able to terminate these contracts due to the discontinuance of the related project(s) and thus avoid paying for the services that have not yet been rendered and our future purchase obligations would reduce accordingly.

Supply Agreements

In connection with our acquisition of ZEVALIN, RIT assumed a supply agreement with Biogen Idec Inc., or Biogen, to manufacture ZEVALIN for sale in the U.S. pursuant to which we would purchase from Biogen, and Biogen would provide to us, kits to make ZEVALIN doses for sale to end-users in the U.S. at a “cost plus” manufacturing price. In connection with our acquisition of Captisol-enabled melphalan, we entered into a supply agreement with Ligand pursuant to which, subject to certain exceptions, we agreed to purchase our requirements of Captisol from Ligand.

Employment Agreement

We have entered into an employment agreement with Dr. Rajesh C. Shrotriya, our Chairman, President and Chief Executive Officer, which expires January 2, 2014. The employment agreement automatically renews for subsequent one-year calendar terms unless either party gives written notice of such party’s intent not to renew the agreement at least 90 days prior to the commencement of the new term. The employment agreement requires Dr. Shrotriya to devote his full working time and effort to our business and affairs during the term of the agreement. The employment agreement provides for a minimum annual base salary with annual increases, periodic bonuses and option grants as determined by the Compensation Committee of our Board of Directors.

Spectrum Pharmaceuticals, Inc. et al. (Filed April 24, 2013 in the United States District Court, District of Nevada; Case Number 3:2013-cv-00212-RCJ-VPC). These putative class actions raise substantially identical claims and allegations against defendants Spectrum Pharmaceuticals, Inc., Dr. Rajesh C. Shrotriya, Brett L. Scott, and Joseph Kenneth Keller. The alleged class period is August 8, 2012 to March 12, 2013. The lawsuits allege a violation of Section 10(b) of the Securities Exchange Act of 1934 against all defendants and control person liability, as a violation of Section 20(b) of the Securities Exchange Act of 1934, against the individual defendants. The claims purportedly stem from the Company’s March 12, 2013 press release, in which it announced that it anticipated a change in ordering patterns of FUSILEV. The complaints allege that, as a result of the March 12, 2013 press release, the Company’s stock price declined. The complaints further allege that during the putative class period certain defendants made misleadingly optimistic statements about FUSILEV sales, which inflated the trading price of Company stock. The lawsuits seek relief in the form of monetary damages, costs and fees, and any other equitable or injunctive relief that the court deems appropriate. The putative class action cases have been consolidated. Plaintiffs’ counsel have filed motions for the appointment of a lead plaintiff and lead plaintiff’s legal counsel. The motions are briefed. Plaintiffs’ counsel represent that an amended complaint will be filed following the Court’s decision on lead plaintiff and lead plaintiffs’ legal counsel.

Arora, Gilles Gagnon, Anton Gueth, Joseph Kenneth Keller, Stuart M Krassner, Luigi Lenaz, Anthony E. Maida, Brett L. Scott and Dr. Rajesh C. Shrotriya. The Kakadia lawsuit alleges three counts against all defendants: breach of fiduciary duty; waste of corporate assets; and unjust enrichment. The Besner lawsuit alleges five counts against all defendants: breach of fiduciary duty for disseminating false and misleading information; breach of fiduciary duty for failing to properly oversee and manage the company; abuse of control; gross mismanagement; and waste of corporate assets. The Besner lawsuit also alleges two counts against defendants Dr. Raj Shrotriya, Brett Scott, and Anthony Maida for unjust enrichment and for breach of fiduciary duties for insider selling and misappropriation of information. The complaints similarly allege that defendants knew or should have known that the Company’s statements about future FUSILEV sales were misleadingly optimistic and that these statements inflated the trading price of Company stock. The complaints allege that, as a result of the March 12, 2013 press release, the Company’s stock price declined. The complaints seek compensatory damages, corporate governance reforms, restitution and disgorgement of defendants’ alleged profits, equitable and/or injunctive relief, and costs and fees. The cases have been consolidated and stayed.

SEC Subpoena

On April 1, 2013, the Company received a subpoena from the Securities and Exchange Commission (the “SEC”) for documents pursuant to a formal order of investigation. The subpoena followed the Company’s March 12, 2013 announcement that it anticipated a change in ordering patterns of FUSILEV. The Company is cooperating with the SEC investigation. The Company cannot predict when the SEC will conclude its investigation or the outcome of the investigation.

We are involved with various legal matters arising in the ordinary course of business. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our condensed consolidated results of operations, cash flows or financial condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

4. Fair Value Measurements

We measure fair value based on the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include the following:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. These inputs include quoted prices for similar assets or liabilities; quoted market 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 are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in the assessment of fair value. Cash equivalents consist of certificates of deposit and are valued at cost, which approximates fair value due to the short-term maturities of these instruments. Marketable securities consist of certificates of deposit, US Government Treasury bills, US treasury-backed securities and corporate deposits, which are stated at fair value as it approximates carrying value due to the short term maturities of these instruments.

The fair value of the deferred development cost liability and the deferred payment contingency was valued using the discounted cash flow method of the income approach. The unobservable inputs in the valuation models that have the most significant effect on the fair value of our deferred development cost liability and deferred payment contingency are the determination of the present value factors for future cash flows. The assumptions included internal estimates of research and development personnel needed to perform the research and development services; and estimates of expected cash outflows to third parties for services and supplies over the expected period that the services will be performed, approximately through 2022 for the research and development obligations. We determined the present value factor to be a weighted-average cost of capital of approximately 11.0% in 2013 and 2012.

The fair value of the other long-term liability was classified as Level 3 and valued using the probability of success and the discounted cash flow method of the income approach assuming the FDA approval of Captisol-enabled® melphalan will occur on or about December 31, 2015.

A majority of our financial assets have been classified as Level 2. These assets have been initially valued at the transaction price and subsequently valued utilizing third party pricing services. The pricing services use many observable market inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. We validate the prices provided by our third party pricing services by understanding the models used, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming those securities trade in active markets.

We did not elect the fair value option, as allowed, to account for financial assets and liabilities that were not previously carried at fair value. Therefore, material financial assets and liabilities that are not carried at fair value, such as trade accounts receivable and payable, are reported at their historical carrying values.

The fair value of the deferred development costs and deferred payment contingency are measured at the end of each reporting period using Level 3 inputs. The significant unobservable assumptions we use include the determination of present value factors for future cash flows.

The carrying values of our cash and cash equivalents, marketable securities, other securities and common stock warrants, carried at fair value as of June 30, 2013 are classified in the table below in one of the three categories of the fair value hierarchy described below:

Stockholder's Equity

6 Months Ended

Jun. 30, 2013

Equity [Abstract]

Stockholder's Equity

12. Stockholder’s Equity

Treasury Stock

On August 10, 2012, our Board of Directors authorized the repurchase of up to $100 million of our outstanding common stock through August 1, 2013. The previous authorization was for up to $25 million and covered the period through December 31, 2012. As of June 30, 2013 we have purchased an aggregate of $13.6 million, or 1,338,055 shares, all of which have been retired.

Warrant Activity

We have issued warrants to purchase shares of our common stock to investors as part of financing transactions, or in connection with services rendered by consultants. Our outstanding warrants expire on varying dates through June 2015. Below is a summary of warrant activity during the six months ended June 30, 2013:

	Common Stock Warrants		Weighted Average Exercise Price
Outstanding at December 31, 2012		395,000	$	5.45
Granted		50,000	$	7.51
Outstanding, at June 30, 2013		445,000	$	5.68
Exercisable, at June 30, 2013		395,000	$	5.45

Share-Based Compensation

We record share-based employee compensation expense for all equity-based programs, including stock options, restricted stock grants, 401(k) plan matching and our employee stock purchase plan. Total expense recorded for the three and six month periods ended June 30, 2013 and 2012 is as shown below:

	Three Months Ended June 30,				Six months Ended June 30,
	2013		2012		2013		2012
	($ in ‘000’s)
Research and development	$	485	$	397	$	1,159	$	788
Selling, general and administrative		2,439		2,685		4,512		5,309
Total share based compensation expense	$	2,924	$	3,082	$	5,671	$	6,097

Stock Options

During the three and six month period ended June 30, 2013, the Compensation Committee of our Board of Directors granted stock options at exercise prices equal to or greater than the closing price of our common stock on the trading day prior to the grant date. The weighted average grant date fair value of stock options granted during the six month period ended June 30, 2013 and 2012 were estimated at approximately $8.71 and $7.57, respectively using the Black-Scholes option pricing model with the following assumptions:

	Six-months ended June 30,
	2013			2012
Divided yield		0.00	%		0.00	%
Expected volatility		69.5	%		72.1	%
Risk free interest rate		0.35	%		0.40	%
Expected life (years)		4.95			4.50

Share based compensation expense is recognized only for those awards that are ultimately expected to vest, and we have applied a forfeiture rate to unvested awards for the purpose of calculating the compensation cost. These estimates will be reversed in future periods if actual forfeitures differ from our estimates.

During the three and six months ended June 30, 2013, our share-based charge in connection with the expensing of stock options was approximately $1.6 million and $3.0 million, respectively. During the three and six months ended June 30, 2012, our share-based compensation in connection with the expensing of stock options was approximately $1.3 million and $2.6 million, respectively.

As of June 30, 2013, there was approximately $12.2 million of unrecognized stock-based compensation cost related to stock options which we expect to recognize over a weighted average period of approximately 2.41 years.

Restricted Stock

The fair value of restricted stock awards is the grant date closing market price of our common stock, and is charged to expense over the period of vesting. These awards are subject to forfeiture to the extent that the recipient’s service is terminated prior to the shares becoming vested.

During the three and six month periods ended June 30, 2013, the share-based charge in connection with the expensing of restricted stock awards was approximately $1.1 million and $2.0 million, respectively. During the three and six month periods ended June 30, 2012, the share-based compensation in connection with the expensing of restricted stock awards was approximately $1.3 million and $2.5 million, respectively.

As of June 30, 2013, there was approximately $6.7 million of unrecognized share-based compensation cost related to non-vested restricted stock awards, which is expected to be recognized over a weighted average period of approximately 2.67 years.

401(k) Plan Matching Contribution

During the six month period ended June 30, 2013, we issued 50,970 shares of common stock as our matching contribution of approximately $446,000 for 401(k) contributions made by our employees. During the six month period ended June 30, 2012, we issued 26,154 shares of common stock as our matching contribution of approximately $333,500 for 401(k) contributions made by our employees.

Employee Stock Purchase Plan

Effective July 2009, we adopted the 2009 Employee Stock Purchase Plan (“Purchase Plan”). The Purchase Plan provides our eligible employees with an incentive by providing a method whereby they may voluntarily purchase shares of our common stock upon terms described in the Purchase Plan. The Purchase Plan is designed to be operated on the basis of six consecutive month offering periods commencing January 1 and July 1 of each year. The Purchase Plan provides that eligible employees may authorize payroll deductions to purchase shares of our common stock at 85% of the fair market value of common stock on the first or last day of the applicable purchase period. A participant may purchase a maximum of 50,000 shares of common stock during a 6-month offering period, not to exceed $25,000 worth of stock on the offering date during each plan year. The Purchase Plan terminates in 2019.

A total of 5,000,000 shares of common stock are authorized for issuance under the Purchase Plan, and as of June 30, 2013, 420,046 shares have been issued under the Purchase Plan.

Common Stock Reserved for Future Issuances

As of June 30, 2013, approximately 16.3 million shares of our common stock, when fully vested, were issuable upon conversion or exercise of rights granted under prior financing arrangements, stock options and warrants, as follows:

Conversion of Series E preferred shares	40,000
Exercise of stock options	10,932,574
Exercise of warrants	445,000
Employee stock purchase plan shares reserved for issuance	4,579,954
Long-term retention and management incentive plan shares reserved for issuance	346,500
Total shares of common stock reserved for future issuances	16,344,028

2. Acquisitions

Acquisition of Rights to Captisol-Enabled^® Melphalan

On March 8, 2013, we completed the acquisition of exclusive global development and commercialization rights to Captisol-enabled^®, propylene glycol-free melphalan from CyDex Pharmaceuticals, Inc. a wholly-owned subsidiary of Ligand Pharmaceuticals Incorporated (“Ligand”). The Captisol-enabled melphalan product candidate is currently in a pivotal trial being conducted by Ligand for use as a conditioning treatment prior to autologous stem cell transplant for patients with multiple myeloma. Pursuant to the license agreement, Spectrum assumed the responsibility for the ongoing clinical and regulatory development of the program going forward. Under the agreement, Ligand received a license fee of $3.0 million on April 1, 2013 and is eligible to receive milestone payments upon achievement of certain regulatory and net sales thresholds, as well as royalties upon successful commercialization based on a percentage of net sales of the licensed products in all territories.

We accounted for the acquisition of the rights as a business combination using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the purchase date and be recorded on the balance sheet regardless of the likelihood of success of the related product or technology. The process for estimating the fair values of identifiable intangible assets involves the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. Transaction costs are not included as a component of consideration transferred and were expensed as incurred. The related transaction costs expensed for the three months ended March 31, 2013 were approximately $15,000. There were no corresponding expenses for the three months ended June 30, 2013.

Consideration Transferred

The acquisition-date fair value of the consideration transferred consisted of the following items ($ in 000’s):

Cash consideration	$	3,000
Liability assumed—contingent consideration		4,700
Total purchase consideration	$	7,700

Fair Value Estimate of Asset Acquired and Liability Assumed

The total purchase consideration is allocated to the acquisition of the net tangible and intangible assets based on their estimated fair values as of the closing date. The allocation of the total purchase price to the net assets acquired is as follows ($ in 000’s):

In-process research and development—Captisol-enabled^®, propylene glycol-free melphalan rights $ 7,700

Acquired in-process research and development (“IPR&D) is an intangible asset classified as an indefinite-lived asset until the completion or abandonment of the associated R&D effort, and will be amortized over an estimated useful life to be determined at the date the project is completed. Intangible IPR&D is not amortized during the period that it is considered indefinite-lived but rather tested for impairment.

We estimated the fair value of the in-process research and development using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value estimate took into account our estimates of future incremental earnings that may be achieved upon regulatory approval, promotion and distribution associated with the rights, and included estimated cash flows of approximately 10 years and a discount rate of approximately 25%.

The fair value of the contingent consideration liability assumed was determined using the probability of success and the discounted cash flow method of the income approach assuming the U.S. Food and Drug Administration, or FDA, approval of Captisol-enabled^® melphalan is will occur on or about December 31, 2015. Upon receipt of regulatory approval, Spectrum will be obligated to make a milestone payment to Ligand.

We do not consider the acquisition of the global development and commercialization rights to Captisol-enabled^®, propylene glycol-free melphalan to be a material business combination and, therefore, have not disclosed the pro forma results of operations as required for material business combinations.

Allos Acquisition

Spectrum acquired Allos Therapeutics, Inc. on September 5, 2012 as discussed further in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 filed on February 27, 2013. The results of operations of the Allos acquisition are included in the accompanying condensed consolidated statements of operations for the three and six months ended June 30, 2012. The pro forma results of operations are prepared for comparative purposes only and do not necessarily reflect the results that would have occurred had the acquisition occurred at the beginning of the years presented or the results which may occur in the future. The following unaudited pro forma results of operations for the three and six months ended June 30, 2012 assume the Allos acquisition had occurred on January 1, 2012 ($ in 000’s):

Revolving Line of Credit

5. Revolving Line of Credit

In connection with the Allos Acquisition, we entered into a credit agreement on September 5, 2012, or Credit Agreement, with Bank of America, N.A, as the administrative agent and Wells Fargo Bank, N.A, as an initial lender. The Credit Agreement provides us with a committed $75 million revolving line of credit facility, or Credit Facility. We may increase the Credit Facility up to $125 million, subject to meeting certain customary conditions and obtaining commitments for such increase from the lenders. The Credit Facility expires on September 5, 2014.

The Credit Facility bears interest, at our election, at a rate equal to the London Interbank Offer Rate, or LIBOR rate, or the base rate, plus an applicable margin (4.25% at June 30, 2013). The applicable margin is as follows:

• if the consolidated leverage ratio as of the last test date is less than 0.5:1.0, 1.75% per annum (for LIBOR rate loans) or 0.75% (for base rate loans);

• if the consolidated leverage ratio as of the last test date is greater than 0.5:1.0 but less than 1.0:1.0, 2.00% per annum (for LIBOR rate loans) or 1.00% (for base rate loans); and

• if the consolidated leverage ratio as of the last test date is greater than 1.0:1.0, 2.25% per annum (for LIBOR rate loans) or 1.00% (for base rate loans).

The base rate is subject to a floor that is 100 basis points above the LIBOR rate. The LIBOR rate does not include a floor and, with respect to it, interest periods of 1, 2, 3 and 6 months may be selected. Related interest expense was $572,000 for the six months ended June 30, 2013.

We incurred $976,000 in related loan costs and fees, which were deferred and will be amortized using the effective interest method over 24 months, the term of the Credit Facility. Amortization expense included in interest expense in the accompanying condensed consolidated statements of operations was $244,000 and $0 for the six months ended June 30, 2013 and 2012.

An unused line fee is payable quarterly in an amount ranging from 0.375 to 0.625% of the sum of the average daily unused portion of the facilities during any quarter based upon consolidated leverage ratio as at the last test date. A customary fee is also payable to the administrative agent on an annual basis in advance. Related interest expense for the unused line fee was $118,000 for the six months ended June 30, 2013.

The direct and indirect domestic subsidiaries of the Company, including Allos, as a new wholly-owned subsidiary, guaranty our obligations under the Credit Facility.

The Credit Agreement includes the following quarterly financial covenants:

• The Company may not permit the consolidated interest coverage ratio of the Company and its subsidiaries as of the end of any fiscal quarter to be less than 3.00 to 1.00;

• The Company may not permit the consolidated leverage ratio at any time set forth below to be greater than the ratio set forth below opposite such period:

Measurement Period Ending	Maximum Consolidated Leverage Ratio
Closing Date through September 30, 2012	2.00 to 1.00
December 31, 2012 and each fiscal quarter thereafter	1.50 to 1.00

• The Company may not permit the ratio of (i) the sum of (A) unencumbered cash and cash equivalents of the Company and its subsidiaries on a consolidated basis, plus (B) net accounts receivable of the Company and its subsidiaries on a consolidated basis, to (ii) consolidated funded indebtedness as of the end of any fiscal quarter to be less than 2.00 to 1.00.

In addition, the Credit Agreement includes certain negative covenants that, subject to exceptions, limit our ability to, among other things incur additional indebtedness, engage in future mergers, consolidations, liquidations and dissolutions, sell assets, pay dividends and distributions on or repurchase capital stock, and enter into or amend other material agreements. The Credit Agreement also includes certain customary representations and warranties, affirmative covenants and events of default, which are set forth in more detail in the Credit Agreement.

On the closing date of September 5, 2012, we drew $50 million on the Credit Facility and used the proceeds to pay a portion of the purchase price for Allos. At June 30, 2013, $50 million was outstanding on the Credit Facility and there was $25 million available to borrow. At June 30, 2013, we were in compliance with all financial covenants. In July 2013, we repaid $25 million of the then outstanding balance.

Additional revolving loans may be drawn and all revolving loans may be repaid and re-borrowed from time to time in an amount not to exceed the total commitment amount. Any such loan proceeds may be used for working capital and other general corporate purposes for us or our subsidiaries.

Amendment to Credit Agreement

On July 16, 2013, we entered into an amendment to the Credit Agreement dated as of September 5, 2012 with Bank of America, N.A., in its capacity as administrative agent for the lenders and other parties signatory thereto, to, among other things, permit the acquisition of Talon Therapeutics, Inc., reduce the maximum aggregate borrowing amount under the revolving line of credit to $50 million, and to revise the interest rate on borrowings under the revolving line of credit.

Cash, Equivalents and Marketable Securities

3. Cash, Equivalents and Marketable Securities

As of June 30, 2013, we held substantially all of our cash, equivalents and marketable securities at major financial institutions, which must invest our funds in accordance with our investment policy with the principal objectives of such policy being preservation of capital, fulfillment of liquidity needs and above market returns commensurate with preservation of capital. Our investment policy also requires that investments in marketable securities be in only highly rated instruments, which are primarily US treasury bills or US treasury backed securities, with limitations on investing in securities of any single issuer. We maintain cash balances in excess of federally insured limits in reputable financial institutions. To a limited degree, the Federal Deposit Insurance Corporation and third parties insure these investments. However, these investments are not insured against the possibility of a complete loss of earnings or principal and are inherently subject to the credit risk related to the continued credit worthiness of the underlying issuer and general credit market risks. We manage such risks on our portfolio by investing in highly liquid, highly rated instruments and limit investing in long-term maturity instruments.

Cash, equivalents and marketable securities, including long term bank certificates of deposits, and investments totaled $127.9 million and $145.5 million as of June 30, 2013 and December 31, 2012, respectively. Long term bank certificates of deposit include a $250,000 restricted certificate of deposit that collateralizes tenant improvement obligations to the lessor of our principal offices. The following is a summary of such investments (in 000’s):

Mundipharma Agreements

Text Block [Abstract]

Mundipharma Agreements

10. Mundipharma Agreements

As the result of Allos becoming our wholly owned subsidiary effective September 5, 2012, on a consolidated basis we assumed obligations under a strategic collaboration agreement with Mundipharma, or the Mundipharma Collaboration Agreement, pursuant to which we agreed to collaborate in the development of FOLOTYN according to a mutually agreed-upon development plan, as updated by the parties from time to time. Under the Mundipharma Collaboration Agreement, we retained full commercialization rights for FOLOTYN in the United States and Canada with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world, or the Mundipharma territories.

On May 29, 2013 the Company and Mundipharma entered into an amendment to amend and restate the Collaboration Agreement, referred to as the Amended Collaboration Agreement in order to modify the scope of the licensed territory and the respective development obligations of the parties. As a result of the Amended Collaboration Agreement, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and royalty and milestone rates were modified. In addition, the Company received $7.0 million from Mundipharma. All other terms and conditions remained unchanged from the original collaboration agreement.

Pursuant to the Amended Collaboration Agreement, we may receive potential regulatory milestone payments of up to $16 million and commercial progress- and sales-dependent milestone payments of up to $107 million. All of these remaining potential milestone payments are not deemed to be substantive for accounting purposes and will be recognized when the appropriate revenue recognition criteria have been met. We will also receive tiered double digit royalties based on net sales of FOLOTYN within Mundipharma’s licensed territories consistent with the terms of the original Collaboration Agreement.

The Company also entered into a separate supply agreement with Mundipharma Medical Company, an affiliate of Mundipharma, pursuant to which we have agreed to supply FOLOTYN for use in clinical trials for which Mundipharma bears operational responsibility and to support Mundipharma’s commercial requirements. We refer to this as the Mundipharma Supply Agreement, and we refer to the Mundipharma Supply Agreement and the Amended Collaboration Agreement together as the Amended Mundipharma Agreements.

As part of the original Collaboration Agreement, we were obligated to perform research and development services related to jointly agreed-upon clinical development activities through approximately 2022, with cost sharing as discussed below. The Company recorded the fair value of the related deferred development cost obligation of $12.3 as of September 5, 2012, using the discounted cash flow method of the income approach.

In connection with the Amended Collaboration Agreement, the Company determined that the entire $7.0 million development payment from Mundipharma is allocable as arrangement consideration related to the research and development services obligation described above, resulting in an aggregate development cost liability of $18.7 million at June 30, 2013. The development cost liability includes assumptions about internal estimates of research and development personnel needed to perform the research and development services; and estimates of expected cash outflows to third parties for services and supplies for our projected clinical trial enrollment and patient treatment-related follow up time periods through approximately 2031. As with the Company’s previous accounting for the development cost liability, the Company will reevaluate the measurement of this liability at each subsequent reporting date and record the change in measurement to research and development expense.

Under the original Collaboration Agreement, Mundipharma was initially responsible for 40% of the joint development costs incurred by the parties, which increased to 50% upon the later of (i) the calendar quarter of the first approval of FOLOTYN in the EU for relapsed or refractory PTCL or first-line PTCL, and (ii) the first calendar quarter in which the development cost differential equals or exceeds $15.0 million. The “development cost differential” was defined as the cumulative amount of joint development costs that Mundipharma would have incurred if it was responsible for 50% of the joint development costs rather than its initial 40% share. To the extent that this development cost differential did not meet or exceed $15.0 million by December 31, 2019, then the Company was obligated to pay Mundipharma the difference between $15.0 million and the amount of the development cost differential as of December 31, 2019. The Company recorded the joint development cost reimbursements received from Mundipharma as research and development in the statement of operations; and we record the full amount of our joint development costs as research and development expense. Research and development for the three and six months ended June 30, 2013 included $268,000 and $589,000, respectively, related to the 40% joint development cost reimbursement under the original Collaboration Agreement.

The Amended Collaboration Agreement eliminated the development cost differential computation requirement. Prospectively, the Company and Mundipharma will bear their own development costs. The Amended Collaboration Agreement required Spectrum to compute the remaining development cost differential amount which was $12,099 as of May 31, 2013. The Company determined that the remaining development cost differential liability pursuant to the Amended Collaboration Agreement was $18.7 million which is included in the Company’s balance sheet at June 30, 2013. As a result of the amendment, Spectrum reevaluated the fair value measurement of the related contingent payment obligation and determined that its fair value was zero, as no remaining contingent obligation remained at May 29, 2013. Therefore, the Company recorded the difference between the carrying value and the new fair value of the related contingent payment obligation of $2.4 million at May 29, 2013 to research and development expense in the accompanying statement of operations.

As of June 30, 2013, accounts receivable related to the Mundipharma Agreements totaled $24,000. As of June 30, 2013 and December 31, 2012, deferred amounts related to the Mundipharma Agreements consisted of ($ in 000’s):

	June 30, 2013		December 31, 2012

On May 29, 2013 the Company and Mundipharma entered into an amendment to their collaboration agreement in order to modify the scope of the Mundipharma licensed territories and the respective development obligations of the parties. As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and royalty and milestone rates were modified. The modification of the Company’s associated royalty and milestone rights constituted a change in the contractual provisions under which the Company measured its original acquired intangible asset (FOLOTYN distribution rights) with Mundipharma. The Company determined that an impairment of the Mundipharma intangible asset of $1.0 million resulted from the amendment and is recorded in the amortization and impairment of purchased intangibles in the accompanying statement of operations.

During the six months ended June 30, 2013, ZEVALIN and FOLOTYN intangible amortization of $3.3 million and $5.6 million, respectively, is included in amortization of purchased intangibles. In addition, during the six months ended June 30, 2013, $1.0 million is included in cost of product sales related to FUSILEV milestones.

The accounting policies followed by us and other information are contained in the notes to the Company’s audited consolidated financial statements for the year ended December 31, 2012 included in our Annual Report on Form 10-K filed on February 28, 2013 with the SEC. We have not changed our significant accounting policies as of June 30, 2013. You should read this Quarterly Report on Form 10-Q in connection with the information contained in our Annual Report on Form 10-K filed on February 28, 2013.

Variable Interest Entity

Our Canadian affiliate, Spectrum Pharma Canada, is owned 50% by us and was organized in Quebec, Canada in January 2008. We fund 100% of the expenditures and, as a result, we are the party with the controlling financial interest. We are the primary beneficiary of Spectrum Pharma Canada, which is determined to be a variable interest entity. As a result of this characterization, it is consolidated in our financial statements as though it is a wholly-owned subsidiary. We have eliminated all significant intercompany balances and transactions among the consolidated entities from the condensed consolidated financial statements.

Segment and Geographic Information

We operate in one reportable segment: acquiring, developing and commercializing prescription drug products. We evaluate all revenues by product in the aggregate given the similarity of product, production processes, customers, distribution methods and regulatory environment. Accordingly, we report the accompanying condensed consolidated financial statements in the aggregate, including all of our activities in one reportable segment.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent obligations in the financial statements and accompanying notes. The estimation process requires assumptions to be made about future events and conditions, and as such, is inherently subjective and uncertain. Actual results could differ materially from our estimates.

On an ongoing basis, we evaluate our estimates, including those related to deferred revenue recognition periods, inventories, the impairment of investments, the impairment of goodwill and long-lived assets, contingencies, accrued clinical trial expenses, stock-based compensation, and ongoing litigation, among other estimates. We base our estimates on historical experience and on other assumptions that management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

Revenue Recognition

Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer. We sell our products to wholesalers and distributors of oncology products and directly to the end user, directly or through Group Purchasing Organizations or GPO’s (e.g., certain hospitals or hospital systems and clinics with whom we have entered into a direct purchase agreement). Our wholesalers and distributors purchase our products and sell the products directly to end users, which include, but are not limited to, hospitals, clinics, medical facilities, managed care facilities and private oncology based practices. Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer, and the following additional criteria are met:

(i) the price is substantially fixed and determinable;

(ii) our customer has economic substance apart from that provided by us;

(iii) our customer’s obligation to pay us is not contingent on resale of the product;

(iv) we do not have significant obligations for future performance to directly bring about the resale of our product; and

(v) we have a reasonable basis to estimate future returns.

Generally revenue is recognized when all four of the following criteria are met:

(i) persuasive evidence that an arrangement exists;

(ii) delivery of the products has occurred, or services have been rendered;

(iii) the selling price is both fixed and determinable; and

(iv) collectability is reasonably assured.

We calculate a provision for estimated product returns, sales discounts, rebates, chargebacks and distribution and data fees are established as a reduction of gross product sales at the time such revenues are recognized. Thus, revenue is recorded, net of such estimated provisions. We state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

We utilize a third-party logistics company to store and distribute FUSILEV. The same third party logistics company also stores and ships in the U.S. ZEVALIN kits containing the CD20 MAB.

During 2009, we changed the supply and distribution model for ZEVALIN in the U.S. Previously, we sold ZEVALIN kits containing the CD20 MAB to radiopharmacies, who in turn ordered the radioactive isotope (Y-90 or In-111) separately and radiolabeled (or attached) the radioactive isotope to the CD20 MAB. The radiopharmacy then sold the end user product to the consumer. Under the current model in the U.S. we do not sell the ZEVALIN kits containing the CD20 MAB to the radiopharmacies, but instead contract with them, as a fee-for-service, to radiolabel the individual components of the CD20 MAB to the radioactive isotope, and then, also under a fee-for-service arrangement, have them distribute the end use product to the end user; the clinics, hospitals or other medical settings. In this regard, we now sell the CD20 MAB together with the radioactive isotope in the U.S. as the end user product. In November 2011, we received FDA approval to remove the bioscan and starting in January 2012 we are no longer supplying the imaging kit (In-111) in the U.S. which was formerly used for the bioscan.

Beginning in the second quarter of 2013, we terminated our transition services agreement with Bayer Pharma AG and transitioned to a sales distribution model in Europe. Sales of ZEVALIN to certain new customers will be recognized on a cash basis until collectability is reasonably assured.

Product Returns Allowances

Customers are typically permitted to return products within thirty days after shipment, if incorrectly shipped or not ordered, and six months after the expiration of product dating for FUSILEV, subject to certain restocking fees and preauthorization requirements, as applicable. The returned product is destroyed if it is damaged, quality is compromised or past its expiration date. In general, returned product is not resold. As of each balance sheet date, we estimate potential returns, based on several factors, including: inventory held by distributors, sell through data of distributor sales to end users, customer and end-user ordering and re-ordering patterns, aging of accounts receivables, rates of returns for directly substitutable products and pharmaceutical products for the treatment of therapeutic areas similar to indications served by our products, shelf life of our products, historical rates of actual returns and based on experience of our management with selling similar oncology products. We record an allowance for future returns by reducing product sales and crediting a reserve for returns to increase other accrued obligations at the time of the product sales. No returns reserve is recorded for ZEVALIN since in the U.S. we invoice our end user customers and recognize revenues only when a patient is treated with ZEVALIN and for Ex. U.S. we invoice upon delivery. FOLOTYN returns are limited to defective product or product that was shipped in error.

Government Chargebacks

Our products are subject to certain programs with federal government qualified entities whereby pricing on products is discounted below distributor list price to participating entities. These entities purchase products through distributors at the discounted price, and the distributors charge the difference between their acquisition cost and the discounted price back to us. We account for chargebacks by reducing revenue and establishing an accrual in an amount equal to our estimate of chargeback claims at the time of product sale. We also evaluate the adequacy of previously recorded chargebacks based on data regarding specific entities claims activity over time to adjust current period chargebacks for these same distributors. Due to estimates and assumptions inherent in determining the amount of government chargebacks, the time lag to receive information from distributors, the actual amount of claims for chargebacks may be materially different from our estimates, at which time we would adjust our reserves accordingly.

Discounts

Discounts (generally prompt payment discounts) are accrued at the end of every reporting period based on the gross sales made to customers during the period and based on their terms of trade for a product. We generally review the terms of the contracts, specifically price and discount structures, and payment terms between the customer and us to estimate the discount accrual.

Rebates

Customer rebates are estimated at every period end, based on direct purchases, depending on whether any rebates have been offered based on definitive contractual agreements. The rebates are recognized when products are purchased and a periodic credit is given.

Medicaid Rebates

Our products are subject to state government-managed Medicaid programs whereby discounts and rebates are provided to participating state governments. We record estimated rebates payable under governmental programs, including Medicaid, as a reduction of revenue in the same period the related sale is recorded. Our calculations related to these rebate accruals require estimates, including estimates of customer mix primarily based on a combination of market and clinical research, to determine which sales will be subject to rebates and the amount of such rebates. Our estimate of utilization is based on historical claims and supplemented by management’s judgment with respect to many factors, including changes in sales trends, an evaluation of current laws and regulations and product pricing. We update our estimates and assumptions each period and record any necessary adjustments to our reserves. Commencing in the second quarter of 2013, we refined our methodology to estimate rebate claims remaining in channel inventory which resulted in a $1.0 million increase in the Medicaid rebate accrual at June 30, 2013 and corresponding increase to net loss for the three and six months ended June 30, 2013. Additionally, there is a time lag between the date we determine the estimated liability and when we actually pay the liability. Although allowances and accruals are recorded at the time of product sale, certain rebates are typically paid out, on average, up to six months or longer after the sale.

Distribution and Data Fees

Distribution and data fees are paid to authorized wholesalers and specialty distributors of FUSILEV and FOLOTYN as a percentage of WAC for products sold which is a reduction of revenue in the same period the related sale is recorded. The services provided include contract administration, inventory management, product sales reporting by customer and returns for clinics and hospitals. We accrue distribution and data fees based on a percentage of FUSILEV and FOLOTYN revenues that are set and governed by distribution agreements.

Accounts Receivable

We also state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

Milestone Payments

Milestone payments under collaborative arrangements are triggered either by the results of our research and development efforts or by specified sales results by a third-party collaborator. Milestones related to our development-based activities may include initiation of various phases of clinical trials, successful completion of a phase of development or results from a clinical trial, acceptance of a New Drug Application by the FDA or an equivalent filing with an equivalent regulatory agency in another territory, or regulatory approval by the FDA or by an equivalent regulatory agency in another territory. Due to the uncertainty involved in meeting these development-based milestones, the development-based milestones are considered to be substantial (i.e. not just achieved through passage of time) at the inception of the collaboration agreement. In addition, the amounts of the payments assigned thereto are considered to be commensurate with the enhancement of the value of the delivered intellectual property as a result of our performance. Our involvement is necessary to the achievement of development-based milestones. We would account for development-based milestones as revenue upon achievement of the substantive milestone events. Milestones related to sales-based activities may be triggered upon events such as the first commercial sale of a product or when sales first achieve a defined level. These sales-based milestones would be achieved after the completion of our development activities. We would account for the sales-based milestones in the same manner as royalties, with revenue recognized upon achievement of the milestone. In addition, upon the achievement of either development-based or sales-based milestone events, we have no future performance obligations related to any milestone payments.

License Fees

We recognize license fees based on the facts and circumstances of each contractual agreement. In general, we recognize income upon the signing of a contractual agreement that grants rights to products or technology to a third party if we have no further obligation to provide products or services to the third party after entering into the contract.

Research and Development

Research and development expenses include salaries and benefits, clinical trial and related manufacturing costs, contract and other outside service fees, and facilities and overhead costs related to our research and development efforts. Research and development expenses also consist of costs incurred for proprietary and collaborative research and development and include activities such as product registries and investigator-sponsored trials. Research and development costs are expensed as incurred. In certain instances, we enter into agreements with third parties for research and development activities, where we may prepay fees for services at the initiation of the contract. We record such prepayment as a prepaid asset and charge research and development expense over the period of time the contracted research and development services are performed. Other types of arrangements with third parties may be fixed fee or fee for service, and may include monthly payments or payments upon the completion of milestones or receipt of deliverables.

As of each balance sheet date, we review purchase commitments and accrue drug development expenses based on factors such as estimates of work performed, patient enrollment, completion of patient studies and other events. We maintain regular communication with our vendors, including our clinical sites, and gauge the reasonableness of estimates provided. However, actual clinical trial costs may differ materially from estimated clinical trial costs and are adjusted for in the period in which they become known.

Goodwill and Intangible Assets

Goodwill represents the excess of acquisition cost over the fair value of the net assets of the acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead tested for impairment annually unless there are interim impairment indicators. We perform our annual evaluation as of October 1 each year.

Intangible assets are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable. Our policy is to identify and record impairment losses, if necessary, on intangible product rights when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. It is our policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

We acquired 50% of the rights in RIT in December 2008 and the remaining 50% in March 2009. The purchase price for the acquisition of ZEVALIN rights was allocated to identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date which is being amortized over its useful life of 10 years. Such a valuation requires significant estimates and assumptions including but not limited to: determining the timing and expected costs to complete the in-process projects, projecting regulatory approvals, estimating future cash flows from product sales resulting from in-process projects, and developing appropriate discount rates and probability rates by project. We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions.

Identifiable intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives, ranging from 1 to 10 years.

We acquired all of the oncology drug assets of Targent in April 2006. As part of the consideration for the purchase of these assets, we agreed to pay milestone payments to Targent upon the achievement of certain regulatory events as well as for certain sales levels for FUSILEV within a calendar year. During 2011, we capitalized $16.8 million associated with the achievement of these milestones which are being amortized to cost of product sales sold on a straight-line basis over the estimated useful life of 8.7 years.

On April 1, 2012, we acquired the licensing rights to market ZEVALIN outside of the U.S. (ZEVALIN Rights) from Bayer Pharma AG or Bayer. The process for estimating the fair values of these identifiable intangible assets involved the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. These identified intangible assets are being amortized over the estimated useful life of 10 years.

We acquired Allos on September 5, 2012, and recorded intangible assets related to developed technology and distribution rights. The developed technology and distribution rights are amortized over the expected patent life of 10-15 years. The fair value of these intangible assets was estimated using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value considered our estimates of future incremental earnings that may be achieved by the intangible assets.

With respect to the acquisition we believe the fair values assigned to the assets acquired and liabilities assumed were based upon reasonable assumptions. Our allocation of the purchase price was largely dependent on discounted cash flow analyses of projects and products of Allos. We cannot provide assurance that the underlying assumptions used to forecast the cash flows or the timely and successful completion of such projects will materialize as we estimated. For these reasons, among others, our actual results may vary significantly from the estimated results.

On March 8, 2013, we acquired the global development and commercialization rights to Captisol-enabled^®, propylene glycol-free (PG-free) melphalan and capitalized $7.7 million associated with the in process research and development.

On May 29, 2013, we amended our agreement with Mundipharma (see Notes 6 and 10).

We evaluate the recoverability of indefinite and definite intangible assets whenever events or changes in circumstances indicate that an intangible asset’s carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

(i) a significant decrease in the market value of an asset;

(ii) a significant adverse change in the extent or manner in which an asset is used; or

(iii) an accumulation of costs significantly in excess of the amount originally expected for the acquisition of an asset.

We measure the carrying amount of the asset against the estimated undiscounted future cash flows associated with it. Should the sum of the expected future net cash flows be less than the carrying value of the asset being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds its fair value. We recorded an impairment loss of $1.0 million during the three and six months ended June 30, 2013 related to the amendment of the Mundipharma agreement in May 2013. There were no other impairment losses recorded during the quarters ended June 30, 2013 or 2012.

Acquisitions and Collaborations

For all in-licensed products, we perform an analysis to determine whether we hold a variable interest or interests that give us a controlling financial interest in a variable interest entity. On the basis of our interpretations and conclusions, we determine whether the acquisition falls under the purview of variable interest entity accounting and if so, consider the necessity to consolidate the acquisition. As of June 30, 2013, we determined there were no variable interest entities required to be consolidated other than our Canadian affiliate, Spectrum Pharma Canada.

We also perform an analysis to determine if the inputs and/or processes acquired in an acquisition qualify as a business. On the basis of our interpretations and conclusions, we determine if the in-licensed products qualify as a business and whether to account for such products as a business combination or an asset acquisition. The accounting for acquisitions requires extensive use of estimates and judgments to measure the fair value of the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed. Additionally, we must determine whether an acquired entity is considered to be a business or a set of net assets, because the excess of the purchase price over the fair value of net assets acquired can only be recognized as goodwill in a business combination. The excess of the purchase price over the fair value of the net assets acquired can only be recognized as goodwill in a business combination.

Foreign Currency Translation

We translate the assets and liabilities of our foreign subsidiaries stated in local functional currencies to US dollars at the rates of exchange in effect at the end of the period. Revenues and expenses are translated using rates of exchange in effect during the period. Gains and losses from the translation of financial statements denominated in foreign currencies are included as a separate component of accumulated other comprehensive income (loss) in the statement of comprehensive income (loss).

We record foreign currency transactions at the exchange rate prevailing at the date of the transaction with resultant gains and losses being included in results of operations. Foreign currency transaction gains and losses have not been significant for any period presented.

Comprehensive Income (Loss)

Comprehensive income (loss) is calculated in accordance with authoritative guidance which requires the disclosure of all components of comprehensive income, including net income (loss) and changes in equity during a period from transactions and other events and circumstances generated from non-owner sources. Our accumulated other comprehensive income (loss) at June 30, 2013 and 2012, respectively consisted primarily of foreign currency translation adjustments and net unrealized gains/losses on investments in marketable securities as of that date.

Recently Adopted Accounting Standards

In February 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update that requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amounts are required to be reclassified in their entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance became effective for reporting periods beginning after December 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013 and had no significant reclassifications out of accumulated other comprehensive income to net loss during the six months ended June 30, 2013.

In July 2012, the FASB issued an accounting standards update that gives an entity the option to first assess qualitative factors 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, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. This guidance became effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013. The adoption did not have a material impact on our consolidated financial statements.

New Accounting Standards Not Yet Adopted

In March 2013, the FASB issued an accounting standards update that provides guidance on the accounting for the cumulative translation adjustment (the “CTA”) upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this guidance, an entity should recognize the CTA in earnings based on meeting certain criteria, including when it ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity or upon a sale or transfer that results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets resides. This guidance will be effective for fiscal years beginning on or after December 15, 2013, which will be our fiscal year 2014, with early adoption permitted. We currently do not expect the adoption of the guidance will have a material impact on our consolidated financial statements.

Basic and Diluted Earnings (Loss) per Share

We calculate basic and diluted net income (loss) per share using the weighted average number of common shares outstanding during the periods presented, and adjust the amount of net income (loss) used in this calculation for preferred stock dividends (if any) declared during the period. In periods of a net loss position, basic and diluted loss per share are the same. For the diluted earnings per share calculation, we adjust the weighted average number of common shares outstanding to include dilutive stock options, warrants and other common stock equivalents outstanding during the period.

1A. Restatement of Condensed Consolidated Financial Statements

Overview

The Company has restated its previously issued condensed consolidated financial statements for the three and six months ended June 30, 2013 and 2012, and balance sheet as of December 31, 2012, to correct certain errors as described below:

(i) Our accounting for the intangible asset acquired as part of our September 2012 acquisition of Allos Therapeutics, Inc. This intangible asset was recognized as in-process research & development (IPR&D), but should have instead been recognized as a definite-lived intangible asset. The error resulted in an understatement of amortization of approximately $2.1 million per quarter for this intangible asset.

(ii) An over-accrual of research and development and sales and marketing expenses that accumulated from January 1, 2007 through June 30, 2013. The aggregate impact over this entire period was approximately $7.7 million. As a result, $0.1 million and $0.5 million in the three months ended June 30, 2013 and 2012, respectively, and $0.5 million and $1.0 million in the six months ended June 30, 2013 and 2012, respectively, of excess operating expenses were recognized. The overstatement is comprised of (i) $6.7 million in excess accruals that correspond with our research and development and sales and marketing activities, and (ii) $1.0 million in excess liabilities that were recorded as part of our business combination accounting for the 2009 acquisition of RIT Oncology, LLC. As with the $6.7 million in excess accruals, this $1.0 million does not require settlement, and was not identified as such within a timely manner.

Financial Statement Presentation – Current and Future Periods

Our accompanying December 31, 2012 Condensed Consolidated Balance Sheet reflects the correction of the cumulative error of $7.2 million that existed through that date, as an adjustment to “accumulated deficit,” and the correction of the corresponding financial statement accounts including “deferred tax assets”, “accounts payable and other accrued obligations” and “accrued drug development costs”. The comparative results for the three and six months ended June 30, 2012, within the accompanying Condensed Consolidated Statements of Operations, reflect (a) increases in “amortization and impairment of purchased intangible assets”, (b) increases/reductions in “benefit for income taxes”, and (c) reductions of “selling general and administrative” and “research and development” expenses for the errors that correspond to these periods.

The accompanying restated Condensed Consolidated Financial Information in this Quarterly Report on Form 10-Q as of June 30, 2013 and December 31, 2012, and for the three and six months ended June 30, 2013 and 2012, has been labeled as “As Restated.”

A summary of the impact of the restatement corrections and other immaterial adjustments on the Condensed Consolidated Balance Sheets as of June 30, 2013 and December 31, 2012, and the Condensed Consolidated Statements of Operations, Comprehensive (Loss) Income, and Cash Flows for the three and six months ended June 30, 2013 and 2012 (as applicable), is presented below:

Deferred Compensation Plan

13. Deferred Compensation Plan

On September 2, 2011, the Board of Directors approved the Spectrum Pharmaceuticals, Inc. Deferred Compensation Plan (the “Plan”). The Plan is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended. The Plan is administered by the Compensation Committee of the board of directors, or a designee or designees of the Compensation Committee. The Plan is intended to be an unfunded plan which is maintained primarily to provide deferred compensation benefits for a select group of our employees including management, as selected by the Plan administrator (the “Participants”). Under the Plan, we provide the Participants with the opportunity to make annual elections to defer up to a specified amount or percentage of their eligible cash compensation, as established by the Plan administrator, and we have the option to make discretionary contributions. At June 30, 2013, deferrals and contributions totaling $3.2 million are included in other accrued obligations in the accompanying condensed consolidated balance sheet.

Income Taxes

9. Income Taxes

On an interim basis, we estimate that the anticipated annual effective tax rate for the provision for income taxes and record a quarterly income tax provision in accordance with this anticipated annual rate. The effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as the valuation allowances against deferred tax assets, the recognition or derecognition of tax benefits related to uncertain tax positions, expected utilization of R&D tax credits and changes in or the interpretation of tax laws in jurisdictions where the we conduct business. The American Taxpayer Relief Act of 2012 was enacted on January 2, 2013 and retroactively reinstated the U.S. R&D tax credit to January 1, 2012. During the six months ended June 30, 2013 we recognized $0.4 million as a discrete tax benefit due to the retroactive reinstatement of the U.S. R&D tax credit for 2012.

Our provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax loss and credit carryforwards. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction by jurisdiction basis, and includes a review of all available positive and negative evidence.

Based on the weight of both positive and negative evidence, we concluded that it is more likely than not that the domestic net deferred tax assets would be realized, and therefore, we released our domestic valuation allowance during the quarter ended March 31, 2012. We released approximately $23 million as part of the projected annual effective tax rate and released the remaining $24 million of the domestic valuation allowance as a discrete item in the quarter ended March 31, 2012. We maintain a valuation allowance against our foreign net deferred tax assets as we continue to conclude it not more likely than not that the foreign net deferred tax assets will be realized.

We recognize excess tax benefits associated with share-based compensation to stockholders’ equity only when realized. When assessing whether excess tax benefits relating to share-based compensation have been realized, we follow the with-and-without approach, excluding any indirect effects of the excess tax deductions. Under this approach, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us.

We recognize the impact of a tax position in our financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected in income tax expense.

Business

Business

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biotechnology company with fully integrated commercial and drug development operations, with a primary focus in oncology and hematology. Our strategy is comprised of acquiring, developing and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. We currently market three oncology drugs—FUSILEV^® (levoleucovorin) for injection in the U.S., ZEVALIN^® (ibritumomab tiuxetan) injection for intravenous use, for which we have worldwide rights and FOLOTYN^® a folate analogue metabolic inhibitor designed to accumulate preferentially in cancer cells. We also have a diversified pipeline of product candidates in advanced-stage Phase 2 and Phase 3 studies. We have assembled an integrated in-house scientific team, including formulation development, clinical development, medical research, regulatory affairs, biostatistics and data management, and have established a commercial infrastructure for the marketing of our drug products. We also leverage the expertise of our worldwide partners to assist in the execution of our strategy.

Basis of Presentation

Basis of Presentation

We have prepared the accompanying unaudited condensed consolidated financial statements, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. We have condensed or omitted certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) pursuant to such rules and regulations. On April 1, 2012, Spectrum acquired the licensing rights to market ZEVALIN (the “ZEVALIN Rights”) outside of the U.S. On September 5, 2012, Spectrum acquired Allos Therapeutics, Inc. (“Allos”). Commencing April 1, 2012 and September 5, 2012, respectively, our financial statements include the assets, liabilities, operating results and cash flows of the ZEVALIN Rights and Allos.

The condensed consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The unaudited condensed consolidated financial statements reflect all adjustments, which are normal and recurring, that are, in the opinion of management, necessary to fairly state the financial position as of June 30, 2013 and the results of operations and cash flows for the related interim periods ended June 30, 2013 and 2012. The results of operations and trends for the six months ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any other periods. The unaudited financial statements included in this quarterly report should be read in conjunction with our audited financial statements for the year ended December 31, 2012, included in the Annual Report on Form 10-K filed with the SEC.

Significant Accounting Policies

The accounting policies followed by us and other information are contained in the notes to the Company’s audited consolidated financial statements for the year ended December 31, 2012 included in our Annual Report on Form 10-K filed on February 28, 2013 with the SEC. We have not changed our significant accounting policies as of June 30, 2013. You should read this Quarterly Report on Form 10-Q in connection with the information contained in our Annual Report on Form 10-K filed on February 28, 2013.

Variable Interest Entity

Variable Interest Entity

Our Canadian affiliate, Spectrum Pharma Canada, is owned 50% by us and was organized in Quebec, Canada in January 2008. We fund 100% of the expenditures and, as a result, we are the party with the controlling financial interest. We are the primary beneficiary of Spectrum Pharma Canada, which is determined to be a variable interest entity. As a result of this characterization, it is consolidated in our financial statements as though it is a wholly-owned subsidiary. We have eliminated all significant intercompany balances and transactions among the consolidated entities from the condensed consolidated financial statements.

Segment and Geographic Information

Segment and Geographic Information

We operate in one reportable segment: acquiring, developing and commercializing prescription drug products. We evaluate all revenues by product in the aggregate given the similarity of product, production processes, customers, distribution methods and regulatory environment. Accordingly, we report the accompanying condensed consolidated financial statements in the aggregate, including all of our activities in one reportable segment.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent obligations in the financial statements and accompanying notes. The estimation process requires assumptions to be made about future events and conditions, and as such, is inherently subjective and uncertain. Actual results could differ materially from our estimates.

On an ongoing basis, we evaluate our estimates, including those related to deferred revenue recognition periods, inventories, the impairment of investments, the impairment of goodwill and long-lived assets, contingencies, accrued clinical trial expenses, stock-based compensation, and ongoing litigation, among other estimates. We base our estimates on historical experience and on other assumptions that management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

Revenue Recognition

Revenue Recognition

Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer. We sell our products to wholesalers and distributors of oncology products and directly to the end user, directly or through Group Purchasing Organizations or GPO’s (e.g., certain hospitals or hospital systems and clinics with whom we have entered into a direct purchase agreement). Our wholesalers and distributors purchase our products and sell the products directly to end users, which include, but are not limited to, hospitals, clinics, medical facilities, managed care facilities and private oncology based practices. Revenue from product sales is recognized upon shipment of product when title and risk of loss have transferred to the customer, and the following additional criteria are met:

(i) the price is substantially fixed and determinable;

(ii) our customer has economic substance apart from that provided by us;

(iii) our customer’s obligation to pay us is not contingent on resale of the product;

(iv) we do not have significant obligations for future performance to directly bring about the resale of our product; and

(v) we have a reasonable basis to estimate future returns.

Generally revenue is recognized when all four of the following criteria are met:

(i) persuasive evidence that an arrangement exists;

(ii) delivery of the products has occurred, or services have been rendered;

(iii) the selling price is both fixed and determinable; and

(iv) collectability is reasonably assured.

We calculate a provision for estimated product returns, sales discounts, rebates, chargebacks and distribution and data fees are established as a reduction of gross product sales at the time such revenues are recognized. Thus, revenue is recorded, net of such estimated provisions. We state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

We utilize a third-party logistics company to store and distribute FUSILEV. The same third party logistics company also stores and ships in the U.S. ZEVALIN kits containing the CD20 MAB.

During 2009, we changed the supply and distribution model for ZEVALIN in the U.S. Previously, we sold ZEVALIN kits containing the CD20 MAB to radiopharmacies, who in turn ordered the radioactive isotope (Y-90 or In-111) separately and radiolabeled (or attached) the radioactive isotope to the CD20 MAB. The radiopharmacy then sold the end user product to the consumer. Under the current model in the U.S. we do not sell the ZEVALIN kits containing the CD20 MAB to the radiopharmacies, but instead contract with them, as a fee-for-service, to radiolabel the individual components of the CD20 MAB to the radioactive isotope, and then, also under a fee-for-service arrangement, have them distribute the end use product to the end user; the clinics, hospitals or other medical settings. In this regard, we now sell the CD20 MAB together with the radioactive isotope in the U.S. as the end user product. In November 2011, we received FDA approval to remove the bioscan and starting in January 2012 we are no longer supplying the imaging kit (In-111) in the U.S. which was formerly used for bioscan.

Beginning in the second quarter of 2013, we terminated the Bayer transition services agreement and transitioned to a sales distribution model in Europe. Sales of ZEVALIN to certain new customers will be recognized on a cash basis until collectability is reasonably assured.

Product Returns Allowances

Product Returns Allowances

Customers are typically permitted to return products within thirty days after shipment, if incorrectly shipped or not ordered, and six months after the expiration of product dating for FUSILEV, subject to certain restocking fees and preauthorization requirements, as applicable. The returned product is destroyed if it is damaged, quality is compromised or past its expiration date. In general, returned product is not resold. As of each balance sheet date, we estimate potential returns, based on several factors, including: inventory held by distributors, sell through data of distributor sales to end users, customer and end-user ordering and re-ordering patterns, aging of accounts receivables, rates of returns for directly substitutable products and pharmaceutical products for the treatment of therapeutic areas similar to indications served by our products, shelf life of our products, historical rates of actual returns and based on experience of our management with selling similar oncology products. We record an allowance for future returns by reducing product sales and crediting a reserve for returns to increase other accrued obligations at the time of the product sales. No returns reserve is recorded for ZEVALIN since in the U.S. we invoice our end user customers and recognize revenues only when a patient is treated with ZEVALIN and for Ex. U.S. we invoice upon delivery. FOLOTYN returns are limited to defective product or product that was shipped in error.

Government Chargebacks

Government Chargebacks

Our products are subject to certain programs with federal government qualified entities whereby pricing on products is discounted below distributor list price to participating entities. These entities purchase products through distributors at the discounted price, and the distributors charge the difference between their acquisition cost and the discounted price back to us. We account for chargebacks by reducing revenue and establishing an accrual in an amount equal to our estimate of chargeback claims at the time of product sale. We also evaluate the adequacy of previously recorded chargebacks based on data regarding specific entities claims activity over time to adjust current period chargebacks for these same distributors. Due to estimates and assumptions inherent in determining the amount of government chargebacks, the time lag to receive information from distributors, the actual amount of claims for chargebacks may be materially different from our estimates, at which time we would adjust our reserves accordingly.

Discounts

Discounts

Discounts (generally prompt payment discounts) are accrued at the end of every reporting period based on the gross sales made to customers during the period and based on their terms of trade for a product. We generally review the terms of the contracts, specifically price and discount structures, and payment terms between the customer and us to estimate the discount accrual.

Rebates

Rebates

Customer rebates are estimated at every period end, based on direct purchases, depending on whether any rebates have been offered based on definitive contractual agreements. The rebates are recognized when products are purchased and a periodic credit is given.

Medicaid Rebates

Medicaid Rebates

Our products are subject to state government-managed Medicaid programs whereby discounts and rebates are provided to participating state governments. We record estimated rebates payable under governmental programs, including Medicaid, as a reduction of revenue in the same period the related sale is recorded. Our calculations related to these rebate accruals require estimates, including estimates of customer mix primarily based on a combination of market and clinical research, to determine which sales will be subject to rebates and the amount of such rebates. Our estimate of utilization is based on historical claims and supplemented by management’s judgment with respect to many factors, including changes in sales trends, an evaluation of current laws and regulations and product pricing. We update our estimates and assumptions each period and record any necessary adjustments to our reserves. Commencing in the second quarter of 2013, we refined our methodology to estimate rebate claims remaining in channel inventory which resulted in a $1.0 million increase in the Medicaid rebate accrual at June 30, 2013 and corresponding increase to net loss for the three and six months ended June 30, 2013. Additionally, there is a time lag between the date we determine the estimated liability and when we actually pay the liability. Although allowances and accruals are recorded at the time of product sale, certain rebates are typically paid out, on average, up to six months or longer after the sale.

Distribution and Data Fees

Distribution and Data Fees

Distribution and data fees are paid to authorized wholesalers and specialty distributors of FUSILEV and FOLOTYN as a percentage of WAC for products sold which is a reduction of revenue in the same period the related sale is recorded. The services provided include contract administration, inventory management, product sales reporting by customer, returns for clinics and hospitals. We accrue distribution and data fees based on a percentage of FUSILEV and FOLOTYN revenues that are set and governed by distribution agreements.

Accounts Receivable

Accounts Receivable

We also state the related accounts receivable at net realizable value, with any allowance for doubtful accounts charged to general operating expenses. If revenue from sales is not reasonably determinable due to provisions for estimates, promotional adjustments, price adjustments, returns or any other potential adjustments, we defer the revenue and recognize revenue when the estimates are reasonably determinable, even if the monies for the gross sales have been received.

Milestone Payments

Milestone Payments

Milestone payments under collaborative arrangements are triggered either by the results of our research and development efforts or by specified sales results by a third-party collaborator. Milestones related to our development-based activities may include initiation of various phases of clinical trials, successful completion of a phase of development or results from a clinical trial, acceptance of a New Drug Application by the FDA or an equivalent filing with an equivalent regulatory agency in another territory, or regulatory approval by the FDA or by an equivalent regulatory agency in another territory. Due to the uncertainty involved in meeting these development-based milestones, the development-based milestones are considered to be substantial (i.e. not just achieved through passage of time) at the inception of the collaboration agreement. In addition, the amounts of the payments assigned thereto are considered to be commensurate with the enhancement of the value of the delivered intellectual property as a result of our performance. Our involvement is necessary to the achievement of development-based milestones. We would account for development-based milestones as revenue upon achievement of the substantive milestone events. Milestones related to sales-based activities may be triggered upon events such as the first commercial sale of a product or when sales first achieve a defined level. These sales-based milestones would be achieved after the completion of our development activities. We would account for the sales-based milestones in the same manner as royalties, with revenue recognized upon achievement of the milestone. In addition, upon the achievement of either development-based or sales-based milestone events, we have no future performance obligations related to any milestone payments.

License Fees

License Fees

We recognize license fees based on the facts and circumstances of each contractual agreement. In general, we recognize income upon the signing of a contractual agreement that grants rights to products or technology to a third party if we have no further obligation to provide products or services to the third party after entering into the contract.

Research and Development

Research and Development

Research and development expenses include salaries and benefits, clinical trial and related manufacturing costs, contract and other outside service fees, and facilities and overhead costs related to our research and development efforts. Research and development expenses also consist of costs incurred for proprietary and collaborative research and development and include activities such as product registries and investigator-sponsored trials. Research and development costs are expensed as incurred. In certain instances, we enter into agreements with third parties for research and development activities, where we may prepay fees for services at the initiation of the contract. We record such prepayment as a prepaid asset and charge research and development expense over the period of time the contracted research and development services are performed. Other types of arrangements with third parties may be fixed fee or fee for service, and may include monthly payments or payments upon the completion of milestones or receipt of deliverables.

As of each balance sheet date, we review purchase commitments and accrue drug development expenses based on factors such as estimates of work performed, patient enrollment, completion of patient studies and other events. We maintain regular communication with our vendors, including our clinical sites, and gauge the reasonableness of estimates provided. However, actual clinical trial costs may differ materially from estimated clinical trial costs and are adjusted for in the period in which they become known.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill represents the excess of acquisition cost over the fair value of the net assets of the acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead tested for impairment annually unless there are interim impairment indicators. We perform our annual evaluation as of October 1 each year.

Intangible assets are reviewed for impairment when facts or circumstances suggest that the carrying value of these assets may not be recoverable. Our policy is to identify and record impairment losses, if necessary, on intangible product rights when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. It is our policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

We acquired 50% of the rights in RIT in December 2008 and the remaining 50% in March 2009. The purchase price for the acquisition of ZEVALIN rights was allocated to identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date which is being amortized over its useful life of 10 years. Such a valuation requires significant estimates and assumptions including but not limited to: determining the timing and expected costs to complete the in-process projects, projecting regulatory approvals, estimating future cash flows from product sales resulting from in-process projects, and developing appropriate discount rates and probability rates by project. We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions.

Identifiable intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives, ranging from 1 to 10 years.

We acquired all of the oncology drug assets of Targent in April 2006. As part of the consideration for the purchase of these assets, we agreed to pay milestone payments to Targent upon the achievement of certain regulatory events as well as for certain sales levels for FUSILEV within a calendar year. During 2011, we capitalized $16.8 million associated with the achievement of these milestones which are being amortized to cost of product sales sold on a straight-line basis over the estimated useful life of 8.7 years.

On April 1, 2012, we acquired the licensing rights to market ZEVALIN outside of the U.S. (ZEVALIN Rights) from Bayer Pharma AG or Bayer. The process for estimating the fair values of these identifiable intangible assets involved the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. These identified intangible assets are being amortized over the estimated useful life of 10 years.

We acquired Allos on September 5, 2012, and recorded intangible assets related to developed technology and distribution rights. The developed technology and distribution rights are amortized over the expected patent life of 10-15 years. The fair value of these intangible assets was estimated using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value considered our estimates of future incremental earnings that may be achieved by the intangible assets.

With respect to the acquisition we believe the fair values assigned to the assets acquired and liabilities assumed were based upon reasonable assumptions. Our allocation of the purchase price was largely dependent on discounted cash flow analyses of projects and products of Allos. We cannot provide assurance that the underlying assumptions used to forecast the cash flows or the timely and successful completion of such projects will materialize as we estimated. For these reasons, among others, our actual results may vary significantly from the estimated results.

On March 8, 2013, we acquired the global development and commercialization rights to Captisol-enabled^®, propylene glycol-free (PG-free) melphalan and capitalized $7.7 million associated with the in process research and development.

On May 29, 2013, we amended our agreement with Mundipharma (see Notes 6 and 10).

We evaluate the recoverability of indefinite and definite intangible assets whenever events or changes in circumstances indicate that an intangible asset’s carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

(i) a significant decrease in the market value of an asset;

(ii) a significant adverse change in the extent or manner in which an asset is used; or

(iii) an accumulation of costs significantly in excess of the amount originally expected for the acquisition of an asset.

We measure the carrying amount of the asset against the estimated undiscounted future cash flows associated with it. Should the sum of the expected future net cash flows be less than the carrying value of the asset being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds its fair value. We recorded an impairment loss of $1.0 million during the three and six months ended June 30, 2013 related to the amendment of the Mundipharma agreement in May 2013. There were no other impairment losses recorded during the quarters ended June 30, 2013 or 2012.

Acquisitions and Collaborations

Acquisitions and Collaborations

For all in-licensed products, we perform an analysis to determine whether we hold a variable interest or interests that give us a controlling financial interest in a variable interest entity. On the basis of our interpretations and conclusions, we determine whether the acquisition falls under the purview of variable interest entity accounting and if so, consider the necessity to consolidate the acquisition. As of June 30, 2013, we determined there were no variable interest entities required to be consolidated other than our Canadian affiliate, Spectrum Pharma Canada.

We also perform an analysis to determine if the inputs and/or processes acquired in an acquisition qualify as a business. On the basis of our interpretations and conclusions, we determine if the in-licensed products qualify as a business and whether to account for such products as a business combination or an asset acquisition. The accounting for acquisitions requires extensive use of estimates and judgments to measure the fair value of the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed. Additionally, we must determine whether an acquired entity is considered to be a business or a set of net assets, because the excess of the purchase price over the fair value of net assets acquired can only be recognized as goodwill in a business combination. The excess of the purchase price over the fair value of the net assets acquired can only be recognized as goodwill in a business combination.

Foreign Currency Translation

Foreign Currency Translation

We translate the assets and liabilities of our foreign subsidiaries stated in local functional currencies to US dollars at the rates of exchange in effect at the end of the period. Revenues and expenses are translated using rates of exchange in effect during the period. Gains and losses from the translation of financial statements denominated in foreign currencies are included as a separate component of accumulated other comprehensive income (loss) in the statement of comprehensive income (loss).

We record foreign currency transactions at the exchange rate prevailing at the date of the transaction with resultant gains and losses being included in results of operations. Foreign currency transaction gains and losses have not been significant for any period presented.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

Comprehensive income (loss) is calculated in accordance with authoritative guidance which requires the disclosure of all components of comprehensive income, including net income (loss) and changes in equity during a period from transactions and other events and circumstances generated from non-owner sources. Our accumulated other comprehensive income (loss) at June 30, 2013 and 2012, respectively consisted primarily of foreign currency translation adjustments and net unrealized gains/losses on investments in marketable securities as of that date.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In February 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update that requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amounts are required to be reclassified in their entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This guidance became effective for reporting periods beginning after December 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013 and had no significant reclassifications out of accumulated other comprehensive income to net loss during the six months ended June 30, 2013.

In July 2012, the FASB issued an accounting standards update that gives an entity the option to first assess qualitative factors 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, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. This guidance became effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. We adopted the provisions of the guidance in the first quarter of 2013. The adoption did not have a material impact on our consolidated financial statements.

New Accounting Standards Not Yet Adopted

New Accounting Standards Not Yet Adopted

In March 2013, the FASB issued an accounting standards update that provides guidance on the accounting for the cumulative translation adjustment (the “CTA”) upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this guidance, an entity should recognize the CTA in earnings based on meeting certain criteria, including when it ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity or upon a sale or transfer that results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets resides. This guidance will be effective for fiscal years beginning on or after December 15, 2013, which will be our fiscal year 2014, with early adoption permitted. We currently do not expect the adoption of the guidance will have a material impact on our consolidated financial statements.

Basic and Diluted Earnings (Loss) per Share

Basic and Diluted Earnings (Loss) per Share

We calculate basic and diluted net income (loss) per share using the weighted average number of common shares outstanding during the periods presented, and adjust the amount of net income (loss) used in this calculation for preferred stock dividends (if any) declared during the period. In periods of a net loss position, basic and diluted loss per share are the same. For the diluted earnings per share calculation, we adjust the weighted average number of common shares outstanding to include dilutive stock options, warrants and other common stock equivalents outstanding during the period.

Talon Therapeutics Acquisition

On July 16, 2013, the Company entered into a Securities Purchase Agreement with Eagle Acquisition Merger Sub, Inc., a wholly-owned subsidiary of our company which we refer to herein as Acquisition Sub, and certain stockholders of Talon Therapeutics, Inc., or Talon, whereby, on July 17, 2013, Acquisition Sub purchased all of the shares of common stock of Talon owned by such stockholders, which represented approximately 89% of the outstanding shares of common stock of Talon. On July 16, 2013, we also entered into a Stock Purchase Agreement with Acquisition Sub and Talon, whereby, on July 17, 2013, Acquisition Sub purchased additional shares of common stock from Talon, resulting in Acquisition Sub’s ownership of over 90% of the then outstanding shares of Talon’s common stock. On July 17, 2013, Acquisition Sub consummated a “short form” merger with Talon in accordance with Delaware law in which Acquisition Sub merged with and into Talon, with Talon remaining as the surviving corporation and a wholly-owned subsidiary of the Company. Through the acquisition of Talon, we will gain worldwide rights to Marqibo, an FDA-approved drug that we believe complements our other hematology and oncology products.

In connection with the closing of the acquisition, Spectrum will pay Talon stockholders purchase consideration comprising of an aggregate upfront cash consideration of approximately $11.3 million and issued 3 million shares of its common stock (valued at $8.77 on NASDAQ on July 16, 2013 or approximately $26.3 million) in exchange for the cancellation of all of the outstanding indebtedness under Talon’s credit facility. Talon stockholders will also receive contingent value rights (CVRs) in an aggregate of up to $195.0 million in future cash payments from Spectrum upon the achievement of certain one-time sales-based milestones for Marqibo^® and an approval-based milestone for Menadione Topical Lotion upon satisfaction of the following specific milestones, of which there is no assurance that any may be achieved:

• $5,000,000 upon the achievement of net sales of Marqibo (vincristine sulfate liposome injection) in excess of $30,000,000 in any calendar year;

• $10,000,000 upon the achievement of net sales of Marqibo in excess of $60,000,000 in any calendar year

• $25,000,000 upon the achievement of net sales of Marqibo in excess of $100,000,000 in any calendar year

• $50,000,000 upon the achievement of net sales of Marqibo in excess of $200,000,000 in any calendar year

• $100,000,000 upon the achievement of net sales of Marqibo in excess of $400,000,000 in any calendar year

• $5,000,000 upon receipt of marketing authorization from the FDA regarding Menadione Topical Lotion

The CVRs have an estimated fair value of $6.5 million on the date of the acquisition and will not be publicly traded. The Company also entered into a Registration Rights Agreement pursuant to which we filed a registration statement for purpose of registering for resale under the Securities Act of all the shares of our common stock issued in connection with the cancellation of the indebtedness.

Consideration Transferred

The Talon acquisition purchase price was allocated to tangible and intangible assets acquired and liabilities assumed based upon their estimated fair value at the acquisition date. The following table summarizes the purchase price ($ in 000’s):

Cash consideration	$	11.3
Contingent value right		6.5
Spectrum shares of common stock		26.3
Total purchase consideration	$	44.1

Fair Value Estimate of Assets Acquired and Liabilities Assumed

Under the purchase method of accounting, the total purchase consideration is allocated to Talon net tangible and intangible assets based on the preliminary estimated fair values as of the closing date. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was allocated to goodwill. The goodwill acquired is not deductible for tax purposes. The following table summarizes the fair value of the net assets acquired as of July 17, 2013 ($ in 000’s):

Cash and equivalents	$	131
Inventory		611
Prepaid expenses and other current assets		602
Property and equipment		30
Identifiable intangible assets		46,300
Goodwill		20,606
Total assets acquired		68,280
Accounts payable & accrued liabilities		6,870
Contingent value rights		6,500
Deferred tax liability		17,300
Total liabilities assumed		30,670
Net assets acquired	$	37,610

The acquired Marqibo intangible assets consisted of developed technology and in-process research and development for the treatment of acute lymphoblastic leukemia (“ALL”) and non-Hodgkin’s lymphoma (“NHL”) as follows in the table below ($ in 000’s):

	Value of Intangible Assets Acquired		Weighted-Average Amortization Period
Developed technology—Marqibo for ALL	$	27,800		(1)
In-process research and development—Marqibo for NHL		18,500		(1)
Total identifiable intangible assets	$	46,300

(1) Acquired in-process research and development (“IPR&D”) is an intangible asset classified as an indefinite-lived until the completion or abandonment of the associated R&D effort, and will be amortized over an estimated useful life to be determined at the date the project is completed. Intangible IPR&D is not amortized during the period that it is considered indefinite-lived but rather tested for impairment.

Purchase price adjustments recorded subsequent to the closing date of July 17, 2013 will affect the recorded amount of goodwill.

The fair value of the acquired in-process research and development intangible assets was estimated using the income approach. The income approach uses valuation techniques to convert future amounts to a single present amount (discounted). Our measurement is based on the value indicated by current market expectations about those future amounts. The fair value considered our estimates of future incremental earnings that may be achieved by the intangible assets.

Goodwill is calculated as the excess of the purchase consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisition of Talon includes benefits that the Company believes will result from combining the operations of Talon with the operations of Spectrum and any intangible assets that do not qualify for separate recognition. The Talon acquisition will also allow us to gain additional expertise and intellectual property for the next generation of anti-cancer therapeutics, an expanded and complimentary product mix, and an assembled sales force, which we believe supports the amount of goodwill recognized. Goodwill is not amortized and is not deductible for tax purposes.

Deferred tax liability reflects taxes associated with the acquired in-process research and development assets recognized as part of the acquisition.

With respect to the acquisition discussed above, we believe the preliminary fair values assigned to the assets acquired and liabilities assumed were based upon reasonable assumptions. Actual adjustments will be based on analyses of fair values of identifiable intangible assets, which will be completed after Spectrum obtains a final third-party valuation, performs its own assessments and reviews all available data. The fair value estimates for the purchase price allocation may change if additional information becomes available and could have a material impact.

Proforma information for March 31, 2013 (the last period Talon reported earnings on Form 10-Q) and December 31, 2012 was filed on Form 8K-A on August 6, 2013. There are no Talon revenues and earnings included in the results of the Company for the three and six month period ending June 30, 2013.
