(Unaudited)

1. DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION, AND OPERATING SEGMENT

(a) Description of Business

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biopharma company, with a primary strategy comprised of acquiring, developing, and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. We have an in-house clinical development organization with regulatory and data management capabilities, in addition to commercial infrastructure and a field-based sales force for our marketed products. Currently, we have six approved oncology/hematology products (FUSILEV, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA) that target different types of cancer including: non-Hodgkin’s lymphoma (“NHL”), advanced metastatic colorectal cancer, acute lymphoblastic leukemia, and multiple myeloma (“MM”).

We also have two drugs in mid-to-late stage development (in Phase 2 or Phase 3 clinical trials):

• poziotinib, a novel pan-HER inhibitor used in the treatment of patients with a variety of solid tumors, including breast and lung cancer; and

• ROLONTIS for chemotherapy-induced neutropenia.

(b) Basis of Presentation

Interim Financial Statements

The interim financial data for the three and nine months ended September 30, 2018 and 2017, respectively, is unaudited, and is not necessarily indicative of our operating results for a full year. In the opinion of our management, the interim data includes normal and recurring adjustments necessary for a fair presentation of our financial results for the three and nine months ended September 30, 2018 and 2017. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the U.S. Securities and Exchange Commission (“SEC”) rules and regulations relating to interim financial statements. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements and Notes thereto included within our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (filed with the SEC on March 7, 2018).

Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and with the rules and regulations of the SEC. These financial statements include the financial position, results of operations, and cash flows of Spectrum and its subsidiaries, all of which are wholly-owned (except for Spectrum Pharma Canada (“SPC”), as discussed below). All inter-company accounts and transactions among these legal entities have been eliminated in consolidation.

Variable Interest Entity

We own fifty-percent of SPC, a legal entity organized in Quebec, Canada in January 2008. Some of our clinical studies are conducted through this “variable interest entity” (as defined under applicable GAAP). We fund all of SPC’s operating costs, and since we assume all risks and rewards for this entity, we meet the criteria as being its “primary beneficiary” (as defined under applicable GAAP). Accordingly, SPC’s balance sheets and statements of operations are included in our Condensed Consolidated Financial Statements as if it were a wholly-owned subsidiary for all periods presented.

(c) Operating Segment

7

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

We operate in one reportable operating segment that is focused exclusively on developing and marketing oncology and hematology drug products. For the three and nine months ended September 30, 2018 and 2017, all of our revenue and related expenses were solely attributable to these activities. Substantially all of our assets (excluding cash held in certain foreign bank accounts and ZEVALIN distribution rights for ex-U.S. territories - see Note 3(f)) are held in the U.S.

2. USE OF ESTIMATES AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with GAAP requires our management to make informed estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses. These amounts may materially differ from the amounts ultimately realized and reported due to the inherent uncertainty of any estimate or assumption. On an on-going basis, our management evaluates its most critical estimates and assumptions, including those related to: (i) gross-to-net revenue adjustments; (ii) the timing of revenue recognition; (iii) the collectability of customer accounts; (iv) whether the cost of our inventories can be recovered; (v) the recoverability of our reported goodwill and intangible assets; (vi) the realization of our tax assets and estimates of our tax liabilities; (vii) the likelihood of payment and value of contingent liabilities; (viii) the fair value of our investments; (ix) the valuation of our stock options and the periodic expense recognition of stock-based compensation; and (x) the potential outcome of our ongoing or threatened litigation.

Our accounting policies and estimates that most significantly impact the presented amounts within our Condensed Consolidated Financial Statements are further described below:

(i) Revenue Recognition

Impact of the Adoption of the New Revenue Recognition Standard:ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for us on January 1, 2018. Our disclosure within the below sections to this footnote reflects our updated accounting policies that are affected by this new standard. We applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606; thisresulted in the recognition of an aggregate $4.7 million, net of tax, decrease to our January 1, 2018 “accumulated deficit” on our accompanying Condensed Consolidated Balance Sheets for the cumulative impact of applying this new standard. We made no adjustments to our previously-reported total revenues, as those periods continue to be presented in accordance with our historical accounting practices under Topic 605, Revenue Recognition (“Topic 605”). See Notes 4, 5, and 19 for additional quantitative and qualitative revenue disclosures in accordance with Topic 606.

Required Elements of Our Revenue Recognition: Revenue from our (a) product sales, (b) out-license arrangements, and (c) service arrangements is recognized under Topic 606 in a manner that reasonably reflects the delivery of our goods and/or services to customers in return for expected consideration and includes the following elements:

(1) we ensure that we have an executed contract(s) with our customer that we believe is legally enforceable;

(2) we identify the “performance obligations” in the respective contract;

(3) we determine the “transaction price” for each performance obligation in the respective contract;

(4) we allocate the transaction price to each performance obligation; and

(5) we recognize revenue only when we satisfy each performance obligation.

    These five elements, as applied to each of our revenue categories, are summarized below:

(a) Product Sales: We sell our products to pharmaceutical wholesalers/distributors (i.e., our customers), except for our U.S. sales of ZEVALIN in which case the end-user (i.e., clinic or hospital) is our customer. Our wholesalers/distributors in turn sell our products directly to clinics, hospitals, and private oncology-based practices. Revenue from our product sales is recognized as physical delivery of product occurs (when our customer obtains control of the product), in return for agreed-upon consideration.

Our gross product sales (i.e., delivered units multiplied by the contractual price per unit) are reduced by our corresponding gross-to-net (“GTN”) estimates using the “expected value” method, resulting in our reported “product sales, net” in the accompanying Condensed Consolidated Statements of Operations, reflecting the amount we ultimately expect to realize in net cash proceeds, taking into account our current period gross sales and related cash receipts, and the subsequent cash disbursements on these sales that we estimate for the various GTN categories discussed below. These estimates are based upon

8

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

information received from external sources (such as written or oral information obtained from our customers with respect to their period-end inventory levels and sales to end-users during the period), in combination with management’s informed judgments. Due to the inherent uncertainty of these estimates, the actual amount incurred (of some, or all) of product returns, government chargebacks, prompt pay discounts, commercial rebates, Medicaid rebates, and distribution, data, and GPO administrative fees may be materially above or below the amount estimated, then requiring prospective adjustments to our reported net product sales.

These GTN estimate categories are each discussed below:

Product Returns Allowances: Our FUSILEV, MARQIBO, and BELEODAQ customers are contractually permitted to return purchased products beginning at its expiration date and within six months thereafter. Our EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months thereafter (as well as for overstock inventory, as determined by end-users). ZEVALIN and FOLOTYN returns for expiry are not contractually permitted. Returns outside of this aforementioned criteria are not customarily allowed. We estimate expected product returns for our allowance based on our historical return rates. Returned product is typically destroyed, since substantially all returns are due to expiry and cannot be resold.

Government Chargebacks: Our products are subject to pricing limits under certain federal government programs (e.g., Medicare and 340B Drug Pricing Program). Qualifying entities (i.e., end-users) purchase products from our customers at their qualifying discounted price. The chargeback amount we incur represents the difference between our contractual sales price to our customer, and the end-user’s applicable discounted purchase price under the government program. There may be significant lag time between our reported net product sales and our receipt of the corresponding government chargeback claims from our customers.

Prompt Pay Discounts: Discounts for prompt payment are estimated at the time of sale, based on our eligible customers’ prompt payment history and the contractual discount percentage.

Commercial Rebates: Commercial rebates are based on (i) our estimates of end-user purchases through a group purchasing organization (“GPO”), (ii) the corresponding contractual rebate percentage tier we expect each GPO to achieve, and (iii) our estimates of the impact of any prospective rebate program changes made by us.

Medicaid Rebates: Our products are subject to state government-managed Medicaid programs, whereby rebates are issued to participating state governments. These rebates arise when a patient treated with our product is covered under Medicaid, resulting in a discounted price for our product under the applicable Medicaid program. Our Medicaid rebate accrual calculations require us to project the magnitude of our sales, by state, that will be subject to these rebates. There is a significant time lag in us receiving rebate notices from each state (generally several months or longer after our sale is recognized). Our estimates are based on our historical claim levels by state, as supplemented by management’s judgment.

Distribution, Data, and GPO Administrative Fees: Distribution, data, and GPO administrative fees are paid to authorized wholesalers/distributors of our products (except for U.S. sales of ZEVALIN) for various commercial services including: contract administration, inventory management, delivery of end-user sales data, and product returns processing. These fees are based on a contractually-determined percentage of our applicable sales.

(b) License Fees: Our out-license arrangements allow licensees to market our product(s) in certain territories for a specific term (representing the out-license of “functional intellectual property”). These arrangements may include one or more of the following forms of consideration: (i) upfront license fees, (ii) sales royalties, (iii) sales milestone-achievement fees, and (iv) regulatory milestone-achievement fees. We recognize revenue for each based on the contractual terms that establish our right to collect payment once the performance obligation is achieved, as follows:

(1) Upfront License Fees: We determine whether upfront license fees are earned at the time of contract execution (i.e., when rights transfer to the customer) or over the actual (or implied) contractual period of the out-license. As part of this determination, we evaluate whether we have any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer. Our customers’ “distinct” rights to licensed “functional intellectual property” at the time of contract execution results in concurrent revenue recognition of all upfront license fees (assuming that there are no other performance obligations at contract execution that are inseparable from this license transfer).

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

(2) Royalties: Under the “sales-or-usage-based royalty exception” we recognize revenue in the same period that our

licensees complete product sales in their territory for which we are contractually entitled to a percentage-based royalty receipt.

(3) Sales Milestones: Under the “sales-or-usage-based royalty exception” we recognize revenue in full within the period that our licensees achieve annual or aggregate product sales levels in their territories for which we are contractually entitled to a specified lump-sum receipt.

(4) Regulatory Milestones: Under the terms of the respective out-license, regulatory achievements may either be our responsibility, or that of our licensee.

• When our licensee is responsible for the achievement of the regulatory milestone, we recognize revenue in full (for the contractual amount due from our licensee) in the period that the approval occurs (i.e., when the “performance obligation” is satisfied by our customer) under the “most likely amount” method. This revenue recognition remains “constrained” (i.e., not recognized) until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

• When we are responsible for the achievement of a regulatory milestone, the “relative selling price method” is applied for purposes of allocating the transaction price to our performance obligations. In such case, we consider (i) the extent of our effort to achieve the milestone and/or the enhancement of the value of the delivered item(s) as a result of milestone achievement and (ii) if the milestone payment is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. We have historically assessed the contractual value of these milestones upon their achievement to be identical to the allocation of value of our performance obligations and thus representing the “transaction price” for each milestone at contract inception. We recognize this revenue in the period that the regulatory approval occurs (i.e., when we complete the “performance obligation”) under the “most likely amount” method, and revenue recognition is otherwise “constrained” until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

(c) Service Revenue: We receive fees under certain arrangements for (i) sales and marketing services, (ii) supply chain services, (iii) research and development services, and (iv) clinical trial management services.

Our rights to receive payment for these services may be established by (1) a fixed-fee schedule that covers the term of the arrangement, so long as we meet ongoing performance obligations, (2) our completion of product delivery in our capacity as a procurement agent, (3) the successful completion of a phase of drug development, (4) favorable results from a clinical trial, and/or (5) regulatory approval events.

We consider whether revenue associated with these service arrangements is reportable each period, based on our completed services or deliverables (i.e., satisfied “performance obligations”) during the reporting period, and the terms of the arrangement that contractually result in fixed payments due to us. The promised service(s) within these arrangements are distinct and explicitly stated within each contract, and our customer benefits from the separable service(s) delivery/completion. Further, the nature of the promise to our customer as stated within the respective contract is to deliver each named service individually (not a transfer of combined items to which the promised goods or services are inputs), and thus are separable for revenue recognition.

(ii) Cash and Cash Equivalents

Cash and cash equivalents consist of bank deposits and highly liquid investments with maturities of three months or less from the purchase date.

(Unaudited)

(iii) Marketable Securities

Our marketable securities consist of our holdings in equity securities (beginning January 1, 2018 - see Note 3(a)), mutual funds, and bank certificates of deposit (“Bank CDs”). Beginning January 1, 2018, our realized and unrealized (losses) gains on marketable securities are included in “Other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations. Prior to January 1, 2018, our unrealized (losses) gains were included in “other comprehensive (loss) income” on our accompanying Condensed Consolidated Statements of Comprehensive Loss.

(iv) Accounts Receivable

Our accounts receivable are derived from our product sales and license fees (our service revenue is recorded in “other receivables”), and do not bear interest. The allowance for doubtful accounts is management’s best estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance after appropriate collection efforts are exhausted.

(v) Inventories

We value our inventory at the lower of (i) the actual cost of its purchase or manufacture, or (ii) its net realizable value. Inventory cost is determined on the first-in, first-out method. We regularly review our inventory quantities in process of manufacture and on hand. When appropriate, we record a provision for obsolete and excess inventory to derive its new cost basis, which takes into account our sales forecast by product and corresponding expiry dates of each product lot.

Manufacturing costs of drug products that are pending U.S. Food and Drug Administration (“FDA”) approval are expensed through “research and development,” on the accompanying Condensed Consolidated Statements of Operations (rather than being capitalized to “inventories”).

(vi) Property and Equipment

Our property and equipment is stated at historical cost, and is depreciated on a straight-line basis over an estimated useful life that corresponds with its designated asset category. We evaluate the recoverability of “long-lived assets” (which includes property and equipment) whenever events or changes in circumstances in our business indicate that the asset’s carrying amount may not be recoverable through our on-going operations.

(vii) Goodwill and Intangible Assets

Our goodwill represents the excess of our business acquisition cost over the estimated fair value of the net assets acquired in the corresponding transaction. Goodwill has an indefinite accounting life and is therefore not amortized. Instead, goodwill is evaluated for impairment on an annual basis (as of each October 1st), unless we identify impairment indicators that would require earlier testing.

We evaluate the recoverability of indefinite-lived intangible assets at least annually, or whenever events or changes in our business indicate that an intangible asset’s (whether indefinite or definite-lived) carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

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

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

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

Intangible assets with finite useful lives are amortized over their estimated useful lives on a straight-line basis. We review these assets for potential impairment if/when facts or circumstances suggest that the carrying value of these assets may not be recoverable.

(viii) Stock-Based Compensation

11

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

Stock-based compensation expense for equity awards granted to our employees and members of our Board of Directors is recognized on a straight-line basis over each award’s vesting period. Recognized compensation expense is net of an estimated forfeiture rate, representing the percentage of awards that are expected to be forfeited prior to vesting, though is ultimately adjusted for actual forfeitures. We use the Black-Scholes option pricing model to determine the fair value of stock options (as of the date of grant) that have service conditions for vesting. We use the Monte Carlo valuation model to value equity awards (as of the date of grant) that have combined market conditions and service conditions for vesting.

The recognition of stock-based compensation expense and the initial calculation of stock option fair value requires uncertain assumptions, including (a) the pre-vesting forfeiture rate of the award, (b) the expected term that the stock option will remain outstanding, (c) our stock price volatility over the expected term (and that of our designated peer group with respect to certain market-based awards), and (d) the prevailing risk-free interest rate for the period matching the expected term.

With regard to (a)-(d): We estimate forfeiture rates based on our employees’ overall forfeiture history, which we believe will be representative of future results. We estimate the expected term of stock options granted based on our employees’ historical exercise patterns, which we believe will be representative of their future behavior. We estimate the volatility of our common stock on the date of grant based on the historical volatility of our common stock for a look-back period that corresponds with the expected term. We estimate the risk-free interest rate based upon the U.S. Department of the Treasury yields in effect at award grant, for a period equaling the expected term of the stock option.

(ix) Foreign Currency Translation

Our foreign subsidiaries’ separate financial statements are stated in their functional currencies (i.e., local operating currencies). To create the accompanying Condensed Consolidated Financial Statements, we translate the assets and liabilities of our subsidiaries to U.S. dollars at the rates of exchange in effect at the reported balance sheet date; revenues and expenses are translated using the monthly average exchange rates during the reported period. Unrealized gains and losses from these translations are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

We record foreign currency-based transactions (i.e., when not denominated in the functional currency of our transacting legal entity) at the prevailing exchange rate on the date of the transaction. Resulting unrealized foreign exchange gains and losses from these unsettled transactions are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

All unrealized foreign exchange gains and losses associated with our intercompany loans are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets, as these loans with our foreign subsidiaries are not expected to be settled in the “foreseeable future.”

(x) Basic and Diluted Net Loss per Share

We calculate basic and diluted net loss per share using the weighted average number of common shares outstanding during the periods presented. In periods of a net loss, 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 only dilutive stock options, warrants, and other common stock equivalents outstanding during the period.

(xi) Income Taxes

Deferred tax assets and liabilities are recorded based on the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain.

We have recorded a valuation allowance to reduce our deferred tax assets, because we believe that, based upon a weighting of positive and negative factors, it is more likely than not that these deferred tax assets will not be realized. If/when we were to determine that our deferred tax assets are realizable, an adjustment to the corresponding valuation allowance would increase our net income in the period that such determination was made.

(Unaudited)

In the event that we are assessed interest and/or penalties from taxing authorities that have not been previously accrued, such amounts would be included in “(provision) benefit for income taxes” within the Condensed Consolidated Statements of Operations for the period in which we received the notice.

(xii) Research and Development Costs

Our research and development costs are expensed as incurred (see Note 15(c)), or as certain milestone payments become contractually due to our licensors, as triggered by the achievement of clinical or regulatory events.

(xiii) Fair Value Measurements

We determine measurement-date fair value based on the proceeds that would be received through the sale of the asset, or that we would pay to settle or transfer the liability, in an orderly transaction between market participants. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. 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 publicly accessible at the measurement date.

Level 2: Observable prices that are based on inputs not quoted on active markets, but that are corroborated by market data. These inputs may include quoted prices for similar assets or liabilities or quoted market prices in markets that are not active to the general public.

Level 3: Unobservable inputs are used when little or no market data is available.

3. BALANCE SHEET ACCOUNT DETAIL

The composition of selected financial statement captions that comprise the accompanying Condensed Consolidated Balance Sheets are summarized below:

(a) Cash and Cash Equivalents and Marketable Securities

As of September 30, 2018 and December 31, 2017, our “cash and cash equivalents” were held with major financial institutions. Our “marketable securities” primarily relate to our equity holdings in CASI (as defined below).

We maintain cash balances in excess of federally insured limits with reputable financial institutions. To a limited degree, the Federal Deposit Insurance Corporation and other 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 in our portfolio by investing in highly liquid, highly-rated instruments, and limit investing in long-term maturity instruments.

Our investment policy requires that purchased investments in marketable securities may only be in highly-rated instruments, which are primarily U.S. treasury bills or treasury-backed securities, and also limits our investments in securities of any single issuer (excluding any debt or equity securities received from our strategic partners in connection with an out-license arrangement, as discussed in Note 10).

The carrying amount of our equity securities, money market funds, and Bank CDs approximates their fair value (utilizing “Level 1” or “Level 2” inputs – see Note 2(xiii)) because of our ability to immediately convert these instruments into cash with minimal expected change in value.

The following is a summary of our presented “cash and cash equivalents” and “marketable securities”:

* Beginning January 1, 2018, under the new requirements of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities, the unrealized (losses) gains on our CASI Pharmaceuticals, Inc. (NASDAQ: CASI) (“CASI”) equity securities are recognized as a (decrease) increase to “other (expense) income, net” on the Consolidated Statements of Operations (rather than through “other comprehensive (loss) income” on the Consolidated Statements of Comprehensive Loss). Our adoption of ASU 2016-01 on January 1, 2018, resulted in a $17.2 million cumulative-effect adjustment, net of income tax, recorded as a decrease to “accumulated other comprehensive (loss) income” and a decrease to “accumulated deficit” on the accompanying Condensed Consolidated Balance Sheets. Our recognized unrealized loss on these equity securities for the three months ended September 30, 2018 was $40.9 million and our recognized unrealized gain on these equity securities for the nine months ended September 30, 2018 was $17.7 million, as reported in “other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations.

As of September 30, 2018, none of our securities were in an unrealized loss position.

(b) Property and Equipment, net of Accumulated Depreciation

“Property and equipment, net of accumulated depreciation” consists of the following:

	September 30, 2018			December 31, 2017
Computer hardware and software	$	3,076		$	2,994
Laboratory equipment	635			630
Office furniture	212			218
Leasehold improvements	2,938			2,938
Property and equipment, at cost	6,861			6,780
(Less): Accumulated depreciation	(6,424		)	(6,191		)
Property and equipment, net of accumulated depreciation	$	437		$	589

Depreciation expense (included within “total operating costs and expenses” in the accompanying Condensed Consolidated Statements of Operations) for the three and nine months ended September 30, 2018 and 2017, was $0.1 million, $0.1 million, $0.2 million, and $0.2 million, respectively.

New Accounting Standard for Leases, effective January 1, 2019

In February 2016, the FASB issued ASU 2016-02, which amends the FASB Accounting Standards Codification and creates Topic 842, Leases (“Topic 842”). The new topic supersedes Topic 840, Leases and requires additional disclosures regarding our lease arrangements, as well as our presentation of lease assets and lease liabilities (including those for operating leases) on the balance sheet at the present value of lease payments not yet paid, and for us to subsequently apply the “effective

(Unaudited)

interest rate” method” to reduce the lease liability, while amortizing the right-of-use asset for straight-line expense recognition over the lease term.

Topic 842 is effective for us beginning January 1, 2019, and mandates a “modified retrospective” transition method. We are currently assessing the quantitative impact this guidance will have on our consolidated financial statements. However, we presently do not have any capital lease arrangements, or any active contracts that would contain an “embedded lease”. Our current operating lease arrangements affected by this “gross-up” presentation are limited to (1) our executive, administrative, and research and development office facilities and (2) certain office equipment.

(c) Inventories

“Inventories” consists of the following:

	September 30, 2018			December 31, 2017
Raw materials	$	1,870		$	1,077
Work-in-process	2,569			2,551
Finished goods	1,515			5,187
(Less:) Non-current portion of inventories included within "other assets" *	(1,975		)	(3,100		)
Inventories	$	3,979		$	5,715

* The “non-current” portion of inventories is presented within “other assets” in the accompanying Condensed Consolidated Balance Sheets at September 30, 2018 and December 31, 2017, respectively. This value of $2 million at September 30, 2018 represents product that we expect to sell beyond September 30,2019, and the value at December 31, 2017 represented product that we expected to sell beyond December 31, 2018.

(d) Prepaid Expenses and Other Assets

“Prepaid expenses and other assets” consists of the following:

	September 30, 2018		December 31, 2017
Other miscellaneous prepaid operating expenses	$	7,186	$	3,389

(1) Beginning June 2016, we adjusted the amortization period of our FOLOTYN distribution rights to November 2022 from March 2025, representing the period through which we expect to have patent protection from generic competition.

(2) On February 20, 2015, the United States District Court for the District of Nevada found the patent covering FUSILEV to be invalid, which was upheld on appeal. On April 24, 2015, Sandoz began to commercialize a generic version of FUSILEV. This represented a “triggering event” under applicable GAAP in evaluating the value of our FUSILEV distribution rights as of March 31, 2015, resulting in a recognized $7.2 million impairment charge (non-cash) in 2015. We accelerated amortization expense recognition in 2015 for the then remaining net book value of FUSILEV distribution rights.

(3) On May 29, 2013, we amended our FOLOTYN collaboration agreement with Mundipharma. As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and their royalty rates and milestone payments to us were modified. This constituted a change under which we originally valued the FOLOTYN out-license as part of business combination accounting, resulting in a recognized impairment charge (non-cash) of $1 million in 2013.

Intangible asset amortization expense recognized during the three and nine months ended September 30, 2018 and 2017, was $6.9 million, $6.9 million, $20.8 million and $20.7 million, respectively.

Estimated intangible asset amortization expense for the remainder of 2018 and the five succeeding fiscal years and thereafter is as follows:

6. STOCK-BASED COMPENSATION

We report our stock-based compensation expense (inclusive of our incentive stock plan, employee stock purchase plan, and 401(k) contribution matching program) in the accompanying Condensed Consolidated Statements of Operations, based on the assigned department of the recipient. Stock-based compensation expense, included within “total operating costs and expenses” for the three and nine months ended September 30, 2018 and 2017, was as follows (see Note 18 for a discussion of certain immaterial corrections affecting the presented 2017 amounts below):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
Cost of sales	$	80	$	68	$	146	$	150

Total stock-based compensation	$	3,986	$	2,995	$	13,197	$	10,201

7. NET LOSS PER SHARE

Net loss per share was computed by dividing net loss by the weighted average number of common shares outstanding for the three and nine months ended September 30, 2018 and 2017:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2018			2017			2018			2017
Weighted average shares outstanding - basic and diluted	104,106,295			83,463,153			102,571,850			80,177,370
Net loss	$	(68,718	)	$	(18,293	)	$	(70,792	)	$	(62,691	)
Net loss per share – basic and diluted	$	(0.66	)	$	(0.22	)	$	(0.69	)	$	(0.78	)

The below outstanding securities for the three and nine months ended September 30, 2018, were excluded from the calculation above because their impact under the “treasury stock method” and “if-converted method” would have been anti-dilutive due to our net loss per share in each respective period, as summarized below:

Our carrying amounts of financial instruments such as cash equivalents, accounts receivable, prepaid expenses, accounts payable, and accrued liabilities, excluding acquisition-related contingent obligations, approximate their related fair values due to their short-term nature.

9. BUSINESS COMBINATIONS AND CONTINGENT CONSIDERATION

(a) Acquisition of Talon Therapeutics, Inc.

Overview of Talon Acquisition

On July 17, 2013, we purchased all of the outstanding shares of common stock of Talon Therapeutics, Inc. (“Talon”). Through the acquisition of Talon, we gained worldwide rights to MARQIBO. The Talon purchase consideration consisted of (i) an aggregate upfront cash amount of $11.3 million, (ii) issuance of 3 million shares of our common stock, then equivalent to $26.3 million (based on a closing price of $8.77 per share on July 17, 2013), and (iii) the issuance of a contingent value right (“CVR”) initially valued at $6.5 million.

The CVR was valued using a valuation model that probability-weights expected outcomes (ranging from 50% to 100%) and discounts those amounts to their present value, using an appropriate discount rate (these represent unobservable inputs and are therefore classified as Level 3 inputs – see Note 2 (xiii)). The CVR has a maximum payout of $195 million if all sales and regulatory approval milestones are achieved, as summarized below:

• $5 million upon the achievement of net sales of MARQIBO in excess of $30 million in any calendar year

• $10 million upon the achievement of net sales of MARQIBO in excess of $60 million in any calendar year

• $25 million upon the achievement of net sales of MARQIBO in excess of $100 million in any calendar year

• $50 million upon the achievement of net sales of MARQIBO in excess of $200 million in any calendar year

• $100 million upon the achievement of net sales of MARQIBO in excess of $400 million in any calendar year

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

Talon CVR Fair Value as of September 30, 2018 and December 31, 2017

The CVR fair value will continue to be evaluated on a quarterly basis. Current and future changes in its fair value results from the likelihood and timing of milestone achievement and/or the corresponding discount rate applied thereon. Adjustments to CVR fair value are recognized within “change in fair value of contingent consideration related to acquisitions” in the accompanying Condensed Consolidated Statements of Operations.

(b) Acquisition of Rights to EVOMELA and Related Contingent Consideration

Overview of Acquisition of Rights to EVOMELA

In March 2013, we completed the acquisition of exclusive global development and commercialization rights to Captisol-enabled®, propylene glycol-free MELPHALAN (which we branded as “EVOMELA”) for use as a conditioning treatment prior to autologous stem cell transplant for patients with MM. We acquired these rights from CyDex pharmaceuticals, Inc. (“Cydex”) a wholly-owned subsidiary of Ligand Pharmaceuticals Inc. (“Ligand”) for an initial license fee of $3 million, and assumed responsibility for EVOMELA’s then-ongoing clinical and regulatory development program. We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the transaction date.

We are required to pay Ligand additional amounts up to an aggregate of $60 million upon the achievement of annual net sales thresholds (exclusive of the $6 million milestone payment triggered in March 2016, as discussed below), however, we do not expect to achieve these sales thresholds based on our estimated market size for this product and our projected market share at the time of the acquisition and to date. We also must pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.

Our EVOMELA royalty obligation and sales-based milestones are jointly treated as part of an “executory contract” (as defined under GAAP) that is connected with an at-market supply agreement for Captisol that was executed concurrently with this acquisition (requiring the continuing involvement of CyDex). As a result, our royalty obligation and sales-based milestone arrangements are treated as separate transactions, distinct from the consideration for the EVOMELA rights. Our royalty expenses are reported through “cost of sales” in our Condensed Consolidated Statements of Operations in the same period of our recognized revenue for the product sale.

Consideration Transferred

The acquisition-date fair value of the consideration transferred consisted of the following:

Cash consideration	$	3,000
Ligand 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 transaction date. The allocation of the total purchase price to the net assets acquired is as follows:

EVOMELA IPR&D rights $ 7,700

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 net cash flows to a single present value (discounted) amount.  We applied our net cash flow projections for EVOMELA over 10 years and a discount rate of 25%, taking into account our estimates of future incremental earnings that may be achieved upon regulatory approval and commercialization of the product(s). The fair value of the Ligand Contingent Consideration (as defined below) liability was determined using the probability of success and the discounted cash flow method of the income approach (representing unobservable “Level 3” inputs (see Note 2(xiii))for regulatory and sales-based milestones due to Ligand upon achievement).

In March 2016, the FDA approved EVOMELA, triggering a $6 million milestone payment to Ligand (“Ligand Contingent Consideration”) that was paid in April 2016. “EVOMELA IPR&D” of $7.7 million was reclassified in April 2016 to

“EVOMELA distribution rights” that is reported within “Intangible assets, net of accumulated amortization” in the accompanying Condensed Consolidated Balance Sheets as of September 30, 2018 (see Note 3(f)). Amortization related to this intangible asset commenced on April 1, 2016.

(c) Allos Acquisition

We acquired Allos Therapeutics, Inc. (“Allos”) in September 2012 for cash consideration of $205.2 million and assumed its FOLOTYN distribution rights (see Note 14). We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be reported on our balance sheet at their fair values as of the transaction date. We have no ongoing contingent consideration obligations from this transaction.

10. OUT-LICENSE OF MARQIBO, ZEVALIN, & EVOMELA IN CHINA TERRITORY

Overview of CASI Out-License

In September 2014, we executed three perpetual out-license agreements for ZEVALIN, MARQIBO, and EVOMELA (“CASI Out-Licensed Products”) with CASI, a publicly-traded biopharmaceutical company (NASDAQ: CASI) with a primary focus on the China market (collectively, the “CASI Out-License”). Under the CASI Out-License, we received CASI common stock and a secured promissory note; CASI gained the exclusive rights to distribute these drug products in greater China (which includes Taiwan, Hong Kong and Macau).

CASI is responsible for the development and commercialization of these drugs, including the submission of import drug registration applications to regulatory authorities and conducting any confirmatory clinical studies in greater China. We will provide CASI with future commercial supply of the CASI Out-Licensed Products under typical market terms.

Our Ownership in CASI at September 30, 2018

Under certain conditions that expired in December 2017, we had a right to purchase additional shares of CASI common stock in order to maintain our post-investment ownership percentage. During 2017 and 2016, we acquired an additional 1.5 million and 4.6 million CASI common shares at par value, respectively. Our aggregate holding of 11.5 million common shares as of September 30, 2018 represented an approximate 12.36% ownership in CASI, with a fair market value of $53.9 million (see Note 3(a)).

Proceeds Received from CASI in 2014

The proceeds we received in 2014, and its fair value on the CASI Out-License execution date, consisted of the following:

CASI common stock (5.4 million shares)	$	8,649	(a)
CASI secured promissory note, net of fair value discount ($1.5 million face value and 0.5% annual coupon)	1,310		(b)
Total consideration received, net of fair value discount	$	9,959	(c)

(a) Value determined based on the September 17, 2014 closing price of 5.4 million shares of CASI common stock on the NASDAQ Capital Market of $1.60 per share.

(b) Value estimated using the terms of the $1.5 million promissory note, the application of a synthetic debt rating based on CASI’s publicly-available financial information, and the prevailing interest yields on similar public debt securities as of September 17, 2014. This full balance was reclassified beginning December 31, 2017 to “other assets” (presented within non-current assets on the accompanying Condensed Consolidated Balance Sheets) from “other receivables” (presented within current assets) due to an amended maturity date of September 17, 2019.

(c) Presented within “license fees and service revenue” in the Consolidated Statements of Operations for the year ended December 31, 2015 (see below).

In addition, CASI will be responsible for paying any royalties or milestones that we are obligated to pay to our third-party licensors resulting from the achievement of certain milestones and/or sales of CASI Out-Licensed Products, but only to the extent of the greater China portion of such royalties or milestones.

License Fee Revenue Recognized in 2015

The $9.7 million value of the upfront proceeds (undiscounted, and net of certain foreign exchange adjustments) from CASI were recognized in 2015 within “license fees and service revenue” on our Consolidated Statements of Operations. The delayed timing of this revenue recognition corresponded with the execution of certain supply agreements with CASI for ZEVALIN, MARQIBO, and EVOMELA. These agreements allow CASI to procure CASI Out-Licensed Products directly from approved third parties, and in such case, do not require our future involvement for its commercial supply.

11. OUT-LICENSE OF ZEVALIN IN CERTAIN EX-U.S. TERRITORIES

In November 2015, we entered into an out-license agreement with Mundipharma AG (“Mundipharma”) for its commercialization of ZEVALIN in Asia (excluding India and greater China), Australia, New Zealand, Africa, the Middle East, and Latin America (including the Caribbean). In return, we received $18 million (comprised of $15 million received in December 2015 and $3 million received in January 2016). Of these proceeds, $15 million was recognized and reported within “license fees and service revenue” in the fourth quarter of 2015, and the remaining $3 million payment was recognized in full by June 30, 2017.

In April 2018, we received $2 million due to Mundipharma’s achievement of a specified sales milestone which was recognized in the first quarter of 2018 and reported within “license fees and service revenue” on our accompanying Condensed Consolidated Statements of Operations for the nine months ended September 30, 2018 (see Note 5). Mundipharma is required to reimburse us for our payment of royalties due to Bayer Pharma AG (“Bayer”) from its ZEVALIN sales - see Note 15(b)(ii).

12. CO-PROMOTION ARRANGEMENT WITH EAGLE PHARMACEUTICALS

In November 2015, we executed an agreement with Eagle Pharmaceuticals, Inc. (“Eagle”) whereby designated members of our sales force concurrently marketed up to six of Eagle’s products (along with our products). This arrangement was in return for fixed monthly payments (aggregating $12.8 million) and variable sales-based milestones from Eagle over an 18 month contract term from January 1, 2016 through June 30, 2017 (the “Eagle Agreement”). On July 1, 2017, our sales force ceased marketing Eagle products and the Eagle Agreement expired under its terms.

The fixed receipts from Eagle for our sales activities, as well as reimbursements of third-party marketing services, are recognized within “license fees and service revenue” on our accompanying Condensed Consolidated Statements of Operations, and was $4.7 million for the nine months ended September 30, 2017. No sales-based milestones were achieved.

An allocation of costs for our sales personnel that were dedicated to the Eagle Agreement are reported within “cost of service revenue” on our accompanying Condensed Consolidated Statements of Operations, as are reimbursed costs for Eagle marketing activities; these were an aggregate $4.2 million for the nine months ended September 30, 2017.

13. CONVERTIBLE SENIOR NOTES

Overview of Convertible Notes and Conversion Hedge

On December 17, 2013, we entered into an agreement for the sale of $120 million aggregate principal amount of 2.75% Convertible Senior Notes (equaling 120,000 notes, denominated in $1,000 principal units) due December 2018 (the “2018 Convertible Notes”). As of September 30, 2018 and December 31, 2017, $35.8 million and $40.6 million of principal of the 2018 Convertible Notes was outstanding, respectively, due to our open market purchases discussed below, as well as $4.7 million of principal value, converted by a holder in July 2018 into 451,300 common shares.

The 2018 Convertible Notes are convertible into shares of our common stock at a conversion rate of 95 shares per $1,000 principal units, equating to 3.4 million common shares if fully converted at September 30, 2018. The in-the-money conversion price is equivalent to $10.53 per common share. The conversion rate and conversion price is subject to adjustment under certain limited circumstances. The 2018 Convertible Notes bear interest at a rate of 2.75% per year, payable semiannually in arrears on June 15 and December 15 of each year. The 2018 Convertible Notes will mature and become payable on December 15, 2018, subject to earlier conversion into common stock at the holders’ option.

The sale of the 2018 Convertible Notes closed on December 23, 2013 and we received net proceeds of $115.4 million, after deducting banker and professional fees of $4.6 million. We used a portion of these net proceeds to simultaneously enter into “bought call” and “sold warrant” transactions with Royal Bank of Canada (collectively, the “Conversion Hedge”). We

25

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

recorded the Conversion Hedge on a net cost basis of $13.1 million, as a reduction to “additional paid-in capital” in our accompanying Condensed Consolidated Balance Sheets. Under applicable GAAP, the Conversion Hedge transaction has not been (and is not expected to be) marked-to-market through earnings or comprehensive income.

On and after June 15, 2018, and until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all, or a portion, of their 2018 Convertible Notes. Our stockholders’ approved “flexible settlement” our Annual Meeting of Stockholders on June 29, 2015, though on September 27, 2018, we elected to exclusively settle any and all conversions with our common stock. However, if the holders of our 2018 Convertible Notes do not elect to convert, our December 2018 obligation to repay the remaining principal amount of $35.8 million in cash, plus any accrued and unpaid interest, will remain unchanged.

We entered into Conversion Hedge transactions in December 2013 to reduce the potential dilution to our stockholders and/or offset any cash payments that we are required to make in excess of the principal amount, upon conversion of the 2018 Convertible Notes (in the event that the market price of our common stock is greater than the conversion price). The strike price of the “bought call” is equal to the conversion price and conversion rate of the 2018 Convertible Notes (at such time, it matched the 11.4 million common shares into which the holders could convert the 2018 Convertible Notes); the strike price of our “sold warrant” is $14.03 per share of our common stock, and is also for 11.4 million common shares (reduced by the partial unwinding of these instruments, as discussed above).

Open Market Purchases of 2018 Convertible Notes and Conversion Hedge Unwind in December 2016 and October 2017

In December 2016, we completed two open market purchases of our 2018 Convertible Notes, aggregating 9,963 note units (equivalent to $10 million principal value) for $9 million in cash. We recognized an aggregate loss of $25 thousand on the retirement of these 2018 Convertible Notes (based on their carrying value under GAAP), which is included in “other income (expense), net” on the Consolidated Statements of Operations for the year ended December 31, 2016. Concurrent with these two open market purchases in December 2016, we unwound a portion of our previously sold warrants and previously purchased call options (which were part of our Conversion Hedge described below) for aggregate net proceeds of $21 thousand. We recorded a corresponding net increase to “additional paid-in capital” in the Consolidated Balance Sheets as of December 31, 2016.

In October 2017, we completed an additional open market purchase of our 2018 Convertible Notes, aggregating 69,472 note units (equivalent to $69.5 million principal value) for $27.3 million in cash and 5.4 million newly-issued shares of our common stock, then worth $73 million. We recognized a loss of $0.8 million on the retirement of these 2018 Convertible Notes (based on their carrying value under GAAP), which was included in “other (expense) income, net” on the Consolidated Statements of Operations for the year ended December 31, 2017.

Concurrent with this open market purchase in October 2017, we also unwound a portion of the previously sold warrants and previously purchased call options that were part of our Conversion Hedge for aggregate net proceeds of $5.8 million. We recorded a corresponding net increase to “additional paid-in capital” in the Consolidated Balance Sheets as of December 31, 2017.

14. FOLOTYN LICENSE AGREEMENT AND DEVELOPMENT LIABILITY

As the result of our acquisition of Allos on September 5, 2012 (see Note 9(c)), we assumed a strategic collaboration agreement with Mundipharma (as amended and/or restated, the “Mundipharma Collaboration Agreement”), as well as certain FOLOTYN clinical development obligations (the “FOLOTYN Development Liability”).

Overview of Mundipharma Collaboration Agreement

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. On May 29, 2013, the Mundipharma Collaboration Agreement was amended and restated, in order to modify: (i) the scope of the licensed territory, (ii) milestone payments, (iii) royalty rates, and (iv) drug development obligations. In connection with the amendment and restatement of the Mundipharma Collaboration Agreement, we received a one-time $7 million payment from Mundipharma for certain research and development activities to be performed by us.

As a result of the amendment and restatement of the Mundipharma Collaboration Agreement, (a) Europe and Turkey were excluded from Mundipharma’s commercialization territory, (b) we may receive regulatory milestone payments of up to $16 million, and commercial progress and sales-dependent milestone payments of up to $107 million (see Note 15(b)(vii) for July 2017 achievement), (c) we will receive tiered double-digit royalties based on net sales of FOLOTYN within Mundipharma’s licensed territories, and (d) we and Mundipharma will each bear our own FOLOTYN development costs. Effective as of May 1, 2015, we modified the Mundipharma Collaboration Agreement to revise the conditions for our exercise of the option to gain commercialization rights in Switzerland from Mundipharma, as well as royalties payable to us (in the tiered double-digits) on Mundipharma’s net sales in Switzerland.

FOLOTYN Development Liability

The fair value of the FOLOTYN Development Liability within the accompanying Consolidated Balance Sheets was estimated using the discounted income approach model. The unobservable inputs (i.e., “Level 3” inputs - see Note 2(xiii)) in this valuation model that have the most significant effect on these liabilities include (i) estimates of research and development personnel costs needed to perform the research and development services contractually required, (ii) estimates of expected cash outflows to third parties for these clinical services and supplies during the expected period of performance through 2031, and (iii) an appropriate discount rate for these expenditures. These inputs are reviewed by management on a quarterly basis for continued applicability.

We adjust this liability at each quarter-end, with corresponding adjustments for incurred costs recorded as credits to “research and development” expense in our accompanying Condensed Consolidated Statements of Operations. 

	FOLOTYN Development Liability, Current			FOLOTYN Development Liability, Long Term			FOLOTYN Development Liability, Total
Balance as of December 31, 2017	$	275		$	12,111		$	12,386
Transfer from long-term to current in 2018	206			(206		)	—
(Less): Expenses incurred in 2018	(270		)	—			(270		)
Balance as of September 30, 2018	$	211		$	11,905		$	12,116

15. FINANCIAL COMMITMENTS & CONTINGENCIES AND LICENSE AGREEMENTS

(a) Facility Leases

We lease our principal executive office in Henderson, Nevada under a non-cancelable operating lease expiring April 30, 2019. We also lease our research and development facility in Irvine, California under a non-cancelable operating lease expiring May 31, 2019, in addition to several other administrative office leases. Each lease agreement contains scheduled rent increases which are accounted for on a straight-line basis.

(b) In/Out Licensing Agreements and Co-Development Arrangements

The in-license agreements for our commercialized and development-stage drug products provide us with territory-specific rights to their manufacture and distribution (including further sub-licensing/out-licensing, rights). We are generally responsible for all related clinical development costs, patent filings and maintenance costs, marketing costs, and liability insurance costs. We are also obligated to make specified milestone payments to our licensors upon the achievement of certain regulatory and sales milestones, and to pay royalties based on our net sales of all in-licensed products. We also enter into out-license agreements for territory-specific rights to our drug products which include one or more of: upfront license fees, royalties from our licensees’ sales, and/or milestone payments from our licensees’ sales or regulatory achievements. For certain development-stage drug products, we may enter into cost-sharing arrangements with our licensees and licensors.

Our most significant of these agreements, and the key financial terms and our accounting for each, are summarized below:

(i) ZEVALIN U.S.: In-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. through our wholly-owned subsidiary, RIT Oncology LLC. In accordance with the terms of assumed contracts, we were required to meet specified payment obligations, including a milestone payment to Corixa Corporation of $5 million based on ZEVALIN sales in the United States. As of September 30, 2018 all the patents licensed from Corixa had expired under the terms of the agreement. Under the terms of the agreement, we are no longer obligated to pay U.S. net sales-based royalties in the low to mid-single digits to Genentech, Inc. and mid-teens to Biogen, Inc.

(ii) ZEVALIN Ex-U.S.: In-License and Asset Purchase Agreement with Bayer Pharma

In April 2012, through our wholly-owned subsidiary, Spectrum Pharmaceuticals Cayman, L.P., we completed a €19 million acquisition of licensing rights to market ZEVALIN outside of the U.S. from Bayer. ZEVALIN is currently approved in approximately 40 countries outside the U.S. for the treatment of B-cell NHL, including countries in Europe, Latin America, and Asia.

We amended the agreement in February 2016, which adjusted our tiered royalty to Bayer from the single-digits to 20%. The term of the agreement, as amended, continues until the expiration of the last-to-expire ZEVALIN patent in the relevant country, or 15 years from the date of first commercial sale of ZEVALIN in such country, whichever is longer.

(iii) ZEVALIN Ex-U.S.: Out-License Agreement with Dr. Reddy’s

28

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

In June 2014, we executed an exclusive License Agreement with Dr. Reddy’s Laboratories Ltd. (“Dr. Reddy’s”) for ZEVALIN distribution rights within India. The agreement term is 15 years from the receipt of pending approval of ZEVALIN from the Drug Controller General of India. In December 2014, upon our execution of a drug supply agreement, an upfront and non-refundable payment of $0.5 million was triggered and paid to us in February 2015. The recognition of the applicable portion of this upfront receipt is no longer reported on a straight-line basis within “license fees and service revenue” on our accompanying Condensed Consolidated Statements of Operations, due to the adoption of Topic 606 as of January 1, 2018 (see Note 2(i)). Additionally, sales and regulatory milestones, each aggregating $1.5 million (for a total of $3 million if both are achieved) are due to us upon Dr. Reddy’s achievement of such milestones, as well as a 20% royalty on its net sales of ZEVALIN in India.

(iv) ZEVALIN Ex-U.S.: Out-License Agreement with Mundipharma

In November 2015, we entered into an out-license agreement with Mundipharma for its commercialization of ZEVALIN in Asia (excluding India and Greater China), Australia, New Zealand, Africa, the Middle East, and Latin America (including the Caribbean islands). In return, we received $18 million (comprised of $15 million received in December 2015 and $3 million received in January 2016). Of these proceeds, $15 million was recognized within “license fees and service revenue” in the fourth quarter of 2015, and the remaining $3 million payment was recognized in full by June 30, 2017. Mundipharma is required to reimburse us for our payment of royalties due to Bayer from its ZEVALIN sales (see Note 15(b)(ii)).

In March 2018, Mundipharma achieved a specified sales milestone, resulting in a $2 million receipt due to us (subsequently received in April 2018); this amount was recognized within “license fees and service revenue” on our accompanying Condensed Statements of Operations for the nine months ended September 30, 2018 (see Note 5).

(v) FUSILEV: In-License Agreement with Merck & Cie AG

In May 2006, we amended and restated a license agreement with Merck & Cie AG (“Merck”), which we assumed in connection with our March 2006 acquisition of the assets of Targent, Inc. This provided us with an exclusive license to use regulatory filings related to FUSILEV, and a non-exclusive license under certain patents and know-how to develop, manufacture, and sell FUSILEV in the field of oncology in North America.

The contractual royalty percentage on our FUSILEV net sales due to Merck is set at the mid-single digits; however, in September 2017, we paid Merck $2.6 million in full settlement of all royalty obligations under the agreement. As a result, we are no longer contractually obligated to pay any royalties or milestones for our net sales of FUSILEV.

(vi) FOLOTYN: In-License Agreement with Sloan-Kettering Institute, SRI International and Southern Research Institute

In December 2002, Allos entered into an in-license agreement for the drug now marketed as FOLOTYN with Sloan-Kettering Institute for Cancer Research, SRI International (SRI), and Southern Research Institute. We assumed this agreement when we acquired Allos in September 2012. The agreement provides for our exclusive worldwide rights to a portfolio of patents and patent applications related to FOLOTYN, though we are required to fund certain drug development programs. In addition, we pay graduated royalties to our licensors based on our worldwide annual net sales of FOLOTYN (including our sub- licensees). These royalties are 8% of annual worldwide net sales up to $150 million; 9% of annual worldwide net sales of $150 million through $300 million; and 11% of annual worldwide net sales in excess of $300 million. We are also obligated to remit a $3.5 million payment to SRI upon approval of FOLOTYN by the European Medicines Agency (“EMA”) approval of FOLOTYN. This regulatory milestone has not been met, and no amounts have been accrued in our accompanying Condensed Balance Sheets for its potential achievement.

(vii) FOLOTYN: Out-License Agreement with Mundipharma

As a result of our acquisition of Allos (see Note 10(c)), we assumed “the Mundipharma Collaboration Agreement” as well as certain FOLOTYN clinical development obligations. Under the Mundipharma Collaboration Agreement (see Note 14), we retained full commercialization rights for FOLOTYN in the U.S. and Canada, with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world, except in Europe and Turkey. We are contractually entitled to receive regulatory and sales milestone payments from Mundipharma upon its achievement of such milestones, which aggregate $16 million and $107 million, respectively, as well as tiered double-digit royalties on Mundipharma’s net sales.

In July 2017, FOLOTYN was approved in Japan for the treatment of adult patients with relapsed or refractory peripheral T-cell lymphoma. Consequently, we received $3 million from Mundipharma in August 2017 for this milestone achievement.

29

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

This amount was recognized within “license fees and service revenue” on our Consolidated Statements of Operations for the year ended December 31, 2017.

In August 2017, FOLOTYN was commercially launched in Japan. This triggered a contractual milestone of $2 million from Mundipharma. This amount was recorded within “license fees and service revenue” on our Consolidated Statements of Operations for the year ended December 31, 2017.

(viii) EVOMELA: In-License Agreement with CyDex Pharmaceuticals, Inc.

In March 2013, we completed the acquisition of exclusive global development rights to EVOMELA from CyDex, a wholly-owned subsidiary of Ligand (see Note 9(b)), and assumed responsibility for its then-ongoing clinical and regulatory development program. We filed a New Drug Application (“NDA”) with the FDA in December 2015 for its use as a conditioning treatment prior to autologous stem cell transplant for patients with MM, and in March 2016, the FDA communicated its approval. Consequently, we made a $6 million contractual milestone payment to Ligand in April 2016. We reclassified $7.7 million from “EVOMELA IPR&D rights” to “EVOMELA distribution rights” which is presented within “intangible assets, net of accumulated amortization and impairment charges” (see Note 3(f)) within our accompanying Condensed Consolidated Balance Sheets as of September 30, 2018.

We are required to pay Ligand additional amounts of up to $60 million (exclusive of the $6 million milestone paid in April 2016), upon our achievement of specified net sales thresholds. We are also responsible to pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.

(ix) MARQIBO: Acquisition of Talon Therapeutics, Inc. and Related Contingent Consideration Agreement

In July 2013, we completed the acquisition of Talon, through which we obtained exclusive global development and commercialization rights to MARQIBO (see Note 9(a)). As part of this acquisition, the former Talon stockholders have contingent financial rights that we have valued and presented on our accompanying Condensed Consolidated Balance Sheets as a $5.6 million and $6.2 million liability within “acquisition-related contingent obligations” as of September 30, 2018 and December 31, 2017, respectively. The maximum payout value of the contingent financial rights to the former Talon shareholders is $195 million, assuming we achieve all sales and regulatory approval milestones. In addition, we are contractually obligated to pay royalties in the single digits on our net sales of MARQIBO and a portion of sublicensing revenue may be due upon our receipt of such revenue for MARQIBO.

(x) QAPZOLA: License Agreements with Allergan, Inc. and NDDO Research Foundation

In October 2008, we entered into an exclusive development and commercialization collaboration agreement with Allergan, Inc. (“Allergan”) for QAPZOLA pursuant to which Allergan paid us an up-front non-refundable fee of $41.5 million at execution (which we had recognized in full within “license fees and service revenue” by December 31, 2013).

Concurrently we also entered into a letter agreement with NDDO Research Foundation (“NDDO”), pursuant to which we agreed to pay NDDO the following in relation to QAPZOLA milestones: (a) upon FDA acceptance of our NDA, the issuance of 25,000 of our common shares (which occurred in March 2016 and the $0.1 million value of these shares was included in “research and development” expense for the year ended December 31, 2016), and (b) upon FDA approval, a one-time payment of $0.3 million (which has not yet been met, and no amounts have been accrued in our accompanying Consolidated Balance Sheets for its potential achievement).

In January 2013, we entered into a second amendment to the license, development, supply and distribution agreement with Allergan. This amendment relieved Allergan of its development and commercialization obligations and resulted in our acquisition of its rights in the U.S., Europe, and other territories, in exchange for our agreement to pay a tiered single-digit royalty on our sales of certain products containing QAPZOLA.

(xi) QAPZOLA: Collaboration Agreement with Nippon Kayaku Co. LTD.

In November 2009, we entered into a collaboration agreement with Nippon Kayaku Co., LTD. (“Nippon Kayaku”) for the development and commercialization of QAPZOLA in Asia, except North and South Korea (the “Nippon Kayaku Territory”). In addition, Nippon Kayaku received exclusive rights to QAPZOLA for the treatment of Non-Muscle Invasive Bladder Cancer in the Nippon Kayaku Territory, including Japan and China. Nippon Kayaku will conduct QAPZOLA 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 QAPZOLA in the Nippon Kayaku Territory.

30

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

Under the terms of this agreement, Nippon Kayaku paid us an upfront fee of $15 million (which we recognized within “license fees and service revenue” in full by December 31, 2013). Under the terms of the agreement, we are entitled to receive $10 million and $126 million from Nippon Kayaku upon the achievement of certain regulatory and commercialization milestones, respectively (some of which are our responsibility to achieve). Nippon Kayaku is also obligated to pay us royalties on its net sales of QAPZOLA in the mid-teen digits.

(xii) BELEODAQ: In-License and Collaboration Agreement with Onxeo

In February 2010, we entered into an in-license and collaboration agreement with TopoTarget A/S (now Onxeo DK) (“Onxeo”), for the development and commercialization of BELEODAQ, as amended in October 2013. We paid Onxeo an upfront fee of $30 million (and agreed to additional payments described below) for rights in North America and India, with an option for China. We are contractually obligated to pay royalties in the mid-teen digits on our net sales of BELEODAQ.

All development and studies of BELEODAQ are conducted under a joint development plan (of which we fund 70% and Onxeo funds 30%). We have final decision-making authority for all developmental activities in North America and India (and China upon exercise of our option). Onxeo has final decision-making authority for all developmental activities in all other jurisdictions. In February 2014, upon FDA acceptance of our NDA, we were contractually obligated to issue Onxeo one million shares of our common stock and to make a $10 million milestone payment. The aggregate value of this milestone at achievement was $17.8 million, and was recognized within “research and development” expense in the first quarter of 2014.

In July 2014, we received approval from the FDA for BELEODAQ’s use for injection and treatment of relapsed or refractory peripheral T-cell lymphoma. As a result, we made a second milestone payment to Onxeo of $25 million in November 2014. This amount was capitalized as “BELEODAQ distribution rights” and is presented within “intangible assets, net of accumulated amortization and impairment charges” (see Note 3(f)). We are also contractually obligated to pay Onxeo upon our achievements of other regulatory events and sales thresholds, up to $88 million and $190 million, respectively. These milestone amounts are not included within “total liabilities” in our accompanying Consolidated Balance Sheets.

(xiii) ROLONTIS: Co-Development and Commercialization Agreement with Hanmi Pharmaceutical Co. Ltd

In October 2014, we exercised our option under a License Option and Research Collaboration Agreement dated January 2012 (as amended) with Hanmi Pharmaceutical Co. Ltd., or Hanmi, for ROLONTIS (formerly referred to as “LAPS-G-CSF” or “SPI-2012”), a drug based on Hanmi’s proprietary LAPSCOVERY™ technology for the treatment of chemotherapy induced neutropenia. Under the terms of this agreement, as amended, we have primary financial responsibility for the ROLONTIS development plan and hold its worldwide rights (except for Korea, China, and Japan). We are contractually obligated to pay Hanmi royalties in the mid-teen digits on our net sales of ROLONTIS.

In January 2016, the first patient was dosed with ROLONTIS in a clinical trial. This triggered our contractual milestone payment to Hanmi, and in April 2016, we (i) issued 318,750 shares of our common stock, then valued at $2.3 million, and (ii) remitted a $0.4 million payment to the Internal Revenue Service (the IRS) on its behalf for related tax obligations. This aggregate $2.7 million value was recognized within “research and development” expense in our Consolidated Statements of Operations for the year ended December 31, 2016. We are responsible for further contractual payments upon our achievement of regulatory and sales milestones, up to $13 million and $225 million, respectively. These amounts are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets.

(xiv) Poziotinib: In-License Agreement with Hanmi and Exclusive Patent and Technology License Agreement with MD Anderson

In February 2015, we executed an in-license agreement with Hanmi for poziotinib, a pan-HER inhibitor in Phase 2 clinical trials, (which has also shown single agent activity in the treatment of various cancer types during Phase I studies, including breast, gastric, colorectal, and lung cancers), and made an upfront payment for these rights. This payment was recognized within “research and development” expense in our Consolidated Statements of Operations for the year ended December 31, 2015. We are also contractually obligated to pay Hanmi royalties in the low to mid-teen digits on our net sales of poziotinib.

Under the terms of this agreement, we received the exclusive rights to commercialize poziotinib, excluding Korea and China. Hanmi and its development partners are fully responsible for the completion of on-going Phase 2 trials in Korea. We are financially responsible for all other clinical studies. We are contractually obligated to make payments to Hanmi upon our achievement of certain regulatory and sales milestones, aggregating $33 million and $325 million, respectively, which are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets. We will pay Hanmi royalties

31

Notes to Condensed Consolidated Financial Statements

(Unaudited)

in the low to mid-teen digits on our net sales of poziotinib. These amounts are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets.

In April 2018, we executed an exclusive patent and technology agreement for poziotinib’s use in treating patients with EGFR and HER2 exon 20 mutations in cancer and HER2 exon 19 mutations in cancer with The University of Texas M.D. Anderson Cancer Center (“MD Anderson”) that had discovered its use in treating these patient-types (“Exon 19/20 Patients”). We made an upfront payment of $0.5 million upon this agreement’s execution that was recognized within “research and development” expense in the accompanying Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2018.

We are contractually obligated to make payments to MD Anderson upon our achievement of certain regulatory and sales milestones, aggregating $11 million and $23 million, respectively, which are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets. We will also pay MD Anderson royalties in the low single-digits on our net sales of poziotinib that relate to the treatment of Exon 19/20 Patients.

(xv) ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO: Out-License Agreement with Servier in Canada, Inc. in Canada

In January 2016, we entered into a strategic partnership with Servier Canada, Inc. (“Servier”) for the out-licenses of ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO. We received an aggregate $6 million of upfront proceeds in the first quarter of 2016, which was recognized within “license fees and service revenue” in our Consolidated Statements of Operations for the year ended December 31, 2016. We are also entitled to milestone receipts (aggregating $2 million) upon Servier’s achievement of specific regulatory approvals, and a high single-digit royalty on its sales of these products.

(c) Service Agreements for our Research and Development Activities

We have entered into various contracts with numerous third party service providers for the execution of our research and development initiatives (to which we assign discreet project codes in order to compile and monitor such expenses). These vendors include raw material suppliers and contract manufacturers for drug products not yet FDA approved, clinical trial sites, clinical research organizations, and data monitoring centers, among others. The financial terms of these agreements are varied and generally obligate us to pay in stages, depending on the achievement of certain events specified in the agreements - such as contract execution, progress of service completion, delivery of drug supply, and the dosing of patients in clinical studies.

We recognize these “research and development” expenses and corresponding “accounts payable and other accrued liabilities” in the accompanying financial statements based on estimates of our vendors’ progress of performed services, patient enrollments and dosing, completion of clinical studies, and other events. Should we decide to discontinue and/or slow-down the work on any project, the associated costs for those projects would typically be limited to the extent of the work completed, as we are generally able to terminate these contracts with adequate notice.

(d) Supply and Service Agreements for our Commercial Products

We have entered into various supply and service agreements, and/or have issued purchase orders, which obligate us to complete agreed-upon raw material purchases from certain vendors for the production of our commercialized drug products through designated contract manufacturers. These commitments do not exceed our planned commercial requirements, and the contracted prices do not exceed current fair market value.

(e) Employment Agreements

We previously entered into an employment agreement with our former Chief Executive Officer, Rajesh C. Shrotriya, M.D., under which cash compensation and benefits would become payable to him in the event of termination by us for any reason other than cause, his resignation for good reason, or upon a change in control of our Company. Effective December 17, 2017, Dr. Shrotriya’s employment was terminated without cause. As of December 31, 2017, we accrued for all contractual cash amounts due and unpaid to him within “accrued payroll and benefits” on the accompanying Condensed Consolidated Balance Sheets.

We entered into new employment agreements with each of our named executive officers (chief executive officer, chief operating officer, chief financial officer, and chief legal officer) in April and June 2018, which supersede any prior Change in Control Severance Agreements with such individuals. These new agreements provide for the payment of certain benefits to each executive upon his separation of employment under specified circumstances. These arrangements are designed to encourage each

(Unaudited)

to act in the best interests of our stockholders at all times during the course of a change in control event or other significant transaction.

(f) Deferred Compensation Plan

The Spectrum Pharmaceuticals, Inc. Deferred Compensation Plan (the “DC Plan”) is administered by the Compensation Committee of our Board of Directors and is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended.

The DC Plan is maintained to provide special benefits for a select group of our employees (the “DC Participants”). DC Participants make annual elections to defer a portion of their eligible cash compensation which is then placed into their DC Plan accounts. We match a fixed percentage of these deferrals, and may make additional discretionary contributions. At September 30, 2018 and December 31, 2017, the aggregate value of this DC Plan liability totaled $6.5 million and $11.0 million, respectively, and is included within “accounts payable and other accrued liabilities” and “other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheets.

(g) Litigation

We are involved from time-to-time with various legal matters arising in the ordinary course of business. These claims and legal proceedings are of a nature we believe are normal and incidental to a pharmaceutical business, and may include product liability, intellectual property, employment matters, and other general claims.

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 assessed 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 consolidated results of operations, cash flows, or financial condition.

Stockholder Litigation

Olutayo Ayeni v. Spectrum Pharmaceuticals, Inc., et al. (Filed September 21, 2016 in the United States District Court, Central District of California; Case No. 2:16-cv-07074) (the “Ayeni Action”) and Glen Hartsock v. Spectrum Pharmaceuticals, Inc., et al. (Filed September 28, 2016 in the United States District Court, District Court of Nevada Case; No. 2:16-cv-02279-RFB-GWF) (the “Hartsock Action”). On November 15, 2016, the Ayeni Action was transferred to the United States District Court for the District of Nevada. The parties have stipulated to a consolidation of the Ayeni Action with the Hartsock Action. These class action lawsuits allege that we and certain of our executive officers made false or misleading statements and failed to disclose material facts about our business and the prospects of approval for our NDA to the FDA for QAPZOLA in violation of Section 10(b) (and Rule 10b-5 promulgated thereunder) and 20(a) of the Securities Exchange Act of 1934, as amended. The plaintiffs seek damages, interest, costs, attorneys’ fees, and other unspecified equitable relief. We believe that these claims are without merit, and intend to vigorously defend against these claims. Furthermore, as of September 30, 2018, the value of a potential settlement cannot be reasonably estimated given its highly uncertain nature.

EVOMELA Litigation

We obtained global development and commercialization rights to EVOMELA from CyDex Pharmaceuticals, Inc., a wholly-owned subsidiary of Ligand Pharmaceuticals Incorporated, or CyDex, in March 2013. We thereafter assumed responsibility for completing its clinical trials and were responsible for filing the New Drug Application. Under our license agreement with CyDex, CyDex received a license fee and is eligible to receive milestone payments and royalties. On December 20, 2017, CyDex filed an action against Teva Pharmaceuticals USA, Inc., TEVA Pharmaceuticals Industries Ltd., and Actavis, LLC, together Teva, in the U.S. District Court for the District of Delaware, alleging patent infringement with respect to a paragraph IV certification, or an Abbreviated New Drug Application (“ANDA”), filed with the FDA seeking approval to market a generic version of EVOMELA. CyDex brought suit against Teva to protect its intellectual property rights.”

(Unaudited)

We and Onxeo received a Paragraph IV Notice Letter dated August 21, 2018, notifying us that Fresenius Kabi USA, LLC (“Fresenius”) has submitted to the FDA, an ANDA seeking approval from the FDA to manufacture and market a generic version of BELEODAQ (belinostat) for injection in the U.S. We and Onxeo have filed a patent infringement lawsuit against Fresenius which triggered an automatic stay of this ANDA for 30 months. In addition, BELOEDAQ is protected from competition in the U.S. by an Orphan Drug Exclusivity indication until July 3, 2021.

16. INCOME TAXES

We apply an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods, as required under GAAP. We recorded a provision for income taxes of $8 thousand and a benefit for income taxes of $1.4 million for the nine months ended September 30, 2018 and 2017, respectively. Our ETR differs from the U.S. federal statutory tax rate of 21% primarily as a result of nondeductible expenses, state income taxes, foreign income taxes, and the impact of a valuation allowance on our deferred tax assets.

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. We recognize the impact of a tax position in our financial statements only if that position is more likely than not to be 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.

The intraperiod tax allocation rules require that we allocate the “(provision) benefit for income taxes” between continuing operations and other categories of earnings. In prior periods where we have a year-to-date pre-tax loss from continuing operations and year-to-date pre-tax income in other categories of earnings, such as other comprehensive income, ASC 740-20-45-7 requires that we allocate the income tax provision to other categories of earnings, and then record a related tax benefit in continuing operations. For the three and nine months ended September 30, 2017, we recognized net income from investments and currency transactions within “other comprehensive income” while sustaining losses from continuing operations. As a result of the required allocation under ASC 740-20-45-7, we recorded tax expense of $2.1 and $2.1 million in “other comprehensive income” on the accompanying Condensed Consolidated Statements of Comprehensive Loss, and a benefit for income taxes of $1.5 million and $1.4 million within “benefit for income taxes” on the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017, respectively. Beginning January 1, 2018, as a result of the adoption of ASU 2016-01 Recognition and Measurement of Financial Assets and Liabilities, and related reclassification of gains on investments in equity securities to the Consolidated Statements of Operations, we have recognized currency translation losses in our Condensed Consolidated Statement of Comprehensive Income (Loss). Thus, during the three and nine months ended September 30, 2018, there has been no allocation of tax benefits to the Condensed Consolidated Statements of Operations pursuant to the required allocations under ASC 740-20-45-7.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning in 2018, the transition of U.S. international taxation from a worldwide tax system to a territorial system, which includes a new federal tax on global intangible low-taxed income (Global Minimum Tax, or GMT), and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

The SEC Staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

At December 31, 2017, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments. The provisional amounts described below are subject to revisions as we complete our analysis of the Tax Act, collect data, and interpret any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, or IRS, FASB, and other standard-setting and regulatory bodies. Adjustments to the provisional amounts may materially impact our consolidated income tax provision (benefit) and effective tax rates in the period(s) in which such adjustments are made. Our accounting for the tax effects of the Tax Act will be completed during the one-year measurement period.

Reduction of U.S. Federal Corporate Tax Rate: For certain of our deferred tax assets and deferred tax liabilities, we have recorded a provisional decrease in net deferred tax assets of $38.9 million, with a corresponding decrease in the valuation allowance of $41.4 million and a benefit to income tax expense of $2.5 million for the year ended December 31, 2017. This provisional estimate may be affected by other analyses related to the Tax Act, including, but not limited to, the state tax effect of adjustments made to federal temporary differences.

Deemed Repatriation Transition Tax: Based upon our preliminary analysis, we have concluded that a net accumulated E&P deficit exists as of December 31, 2017 for our foreign subsidiaries. As a result, we did not accrue any provisional transition tax liabilities. We will continue to gather additional and perform additional analyses to more precisely determine past foreign earnings and related taxes and will update our provisional estimate with respect to the transition tax liability when such work is completed within the one-year measurement period.

Valuation Allowance: The Tax Act limits the amount taxpayers are able to deduct for net operating loss carryforwards generated in taxable years beginning after December 31, 2017 to 80% of the taxpayer’s taxable income. However, net operating loss carryforwards generated in taxable years ending after December 31, 2017 can be carried forward indefinitely. A taxable temporary difference associated with an indefinite-lived asset is generally considered to be a source of taxable income to support realization of a net operating loss with an unlimited carryforward period. Due to the restriction on the ability to use the net operating loss with unlimited carryforward periods arising in taxable years beginning after December 31, 2017, only 80% of the indefinite-lived taxable temporary difference would serve as a source of taxable income. As a result, the valuation allowance decreased by $2.9 million related to the 80% utilization of the indefinite-lived taxable temporary as a source of taxable income.

Under GAAP, we are allowed to make an accounting policy choice with respect to the GMT of either (1) treating taxes due on future U.S. inclusions in taxable income related to GMT as a current-period expense when incurred or (2) as a component of deferred income taxes. We will make our accounting policy election for this item when our analysis is complete, during the measurement period.

Due to the valuation allowance on our deferred tax assets, there was no net impact to the tax provision for income taxes arising from the Tax Act for the three and nine months ended September 30, 2018.

17. STOCKHOLDERS’ EQUITY

Sale of Common Stock Under ATM Agreements

In December 2015 and August 2017, we entered into collective at-market-issuance sales agreements with FBR Capital Markets & Co., MLV & Co. LLC, and H.C. Wainwright & Co., LLC. (the “December 2015 ATM Agreement” and the “August 2017 ATM Agreement”, respectively). These agreements allowed us to raise aggregate gross proceeds through these brokers of up to $250 million from the sale of our common stock on the public market.

Through September 30, 2018, we had raised aggregate gross net proceeds of $202.1 million through these at-market sales, of which $128.3 million was raised during the year ended December 31, 2017. We are using these proceeds to continue to develop our product pipeline and to provide additional capital structure flexibility.

We sold and issued shares of our common stock under both the December 2015 ATM Agreement and August 2017 ATM Agreement, summarized as follows:

There were no sales of our common stock under the August 2017 ATM Agreement during the nine months ended September 30, 2018.

18. IMMATERIAL RESTATEMENT OF PRIOR PERIOD FINANCIAL STATEMENTS FOR STOCK-BASED COMPENSATION

Subsequent to the issuance of our unaudited interim financial statements for the quarter and year-to-date periods ended September 30, 2017, our management identified certain immaterial errors within previously reported operating expense captions of “selling, general, and administrative” and “research and development” that solely relate to our stock-based compensation recognition (see Note 6). These errors were primarily the result of an improper system setting during our 2012 implementation of our then-new stock-based compensation software. Consequently, incremental expense for the reversal of previously applied forfeiture estimates was not timely recognized upon the full vesting of each award, as required; this error persisted through September 30, 2017. We considered these errors from a qualitative and quantitative perspective, and concluded they were not material to each prior period. However, we have restated our accompanying Condensed Consolidated Financial Statements to correct for these immaterial errors for the prior-year interim period presented.

Restated Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017:

	Three Months Ended September 30, 2017						Nine Months Ended September 30, 2017

Other than for the correction to net loss and stock-based compensation, the restatement adjustments had no impact on cash flows from operating, investing, or financing activities for the nine months ended September 30, 2017. Furthermore, such restatement adjustments had no impact to prior period total assets, total liabilities or total stockholders’ equity.

19. NEW REVENUE RECOGNITION STANDARD

Notes to Condensed Consolidated Financial Statements

(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)

(Unaudited)

As discussed in Note 2(i), Topic 606 became effective for us on January 1, 2018. We applied the “modified retrospective” transition method for the accounting of open contracts at implementation. This resulted in the recognition of an aggregate $4.7 million increase to our January 1, 2018 retained earnings (for the tax-effected cumulative impact of initially applying this new standard, with no adjustments to our prior period financial statements). Our prior periods continue to be presented in accordance with our historical revenue accounting practices under Topic 605.

Had we continued to apply Topic 605 for our revenue recognition for the three and nine months ended September 30, 2018, the “pro forma” impact to our Condensed Consolidated Statements of Operations is presented in the table below:

	Three Months Ended September 30, 2018

20. SUBSEQUENT EVENT

FDA Approval of KHAPZORY

On October 23, 2018, we obtained FDA approval to commercialize KHAPZORY (levoleucovorin) for injection, a folate analog for three indications: (i) rescue after high-dose methotrexate therapy in patients with isteosarcoma; (ii) diminishing the toxicity associated with overdosage of folic acid antagonists or impaired methotrexate elimination; and (iii) the treatment of patients with metastatic colorectal cancer in combination with fluorouracil. We completed a contractually-required licensor payment of $2.7 million for this milestone achievement that will be included within “intangible assets, net of accumulated depreciation” on our Consolidated Balance Sheets at December 31, 2018.

Company Overview

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biopharma company, with a primary strategy comprised of acquiring, developing, and commercializing a broad and diverse pipeline of clinical and commercial products. We have an in-house clinical development organization with regulatory and data management capabilities, in addition to commercial infrastructure and a field-based sales force for our marketed products. Currently, we have six approved oncology/hematology products (FUSILEV, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA) that target different types of cancer including: non-Hodgkin’s lymphoma, advanced metastatic colorectal cancer, acute lymphoblastic leukemia, and multiple myeloma.

We also have two drugs in mid-to-late stage development (in Phase 2 or Phase 3 clinical trials):

• Poziotinib, a novel pan-HER inhibitor used in the treatment of patients with a variety of solid tumors, including breast and lung cancer; and

• ROLONTIS for chemotherapy-induced neutropenia.

Recent Highlights of Product Development Initiatives

We continued to make meaningful progress in the advancement of our product pipeline during 2018, as summarized below:

• poziotinib, an irreversible tyrosine kinase inhibitor:

Non-small cell lung cancer (“NSCLC”) tumors with EGFR or HER2 exon 20 insertion mutations are rare, and have generally not been responsive to several other tyrosine kinase inhibitors (“TKIs”). Consequently, there are no drugs currently approved to treat patients with these mutations, who have a poor prognosis of approximately two

40

months of progression-free survival. However, poziotinib, due to its unique chemical structure and characteristics, is believed to inhibit cell growth of tumors with EGFR or HER2 exon 20 insertion mutations.

poziotinib use in Treatment of Lung Cancer

In collaboration with The University of Texas MD Anderson Cancer Center (“MD Anderson”), an investigator-sponsored Phase 2 trial was initiated in NSCLC patients with EGFR or HER2 exon 20 mutations. The EGFR cohort of 50 patients has completed enrollment; the enrollment of the HER2 cohort of 30 patients is ongoing. The poziotinib NSCLC clinical program for patients with EGFR or HER2 exon 20 insertion mutations currently consists of this Phase 2 investigator-initiated study at MD Anderson and a Phase 2 pivotal, Spectrum-sponsored, multi-center, global study (“ZENITH20”) with active sites in the U.S. and future centers planned in Canada and Europe. The overall poziotinib clinical development program is focused on four pillars, including previously treated NSCLC, first-line treatment of NSCLC, combination therapy and treatment of other solid tumors.

On April 23, 2018, poziotinib data was published in Nature Medicine from the ongoing study led by MD Anderson, which provided an update on the preliminary clinical data of poziotinib dosing on the 11 NSCLC patients previously reported at World Lung Conference on Lung Cancer in October 2017. This publication summarized the current preclinical and clinical data with poziotinib for EGFR and HER2 exon 20 mutations. MD Anderson utilized in silico, in vitro, and in vivo testing to model structural alterations induced by exon 20 mutations and identify potentially effective inhibitors. 3-D modeling indicated alterations restricted the size of the drug binding pocket, limiting the binding of large, rigid inhibitors. It was found that poziotinib, due to its small size and flexibility, can circumvent these steric changes, and is a potent inhibitor of the most common EGFR and HER2 exon 20 mutants. Poziotinib demonstrated greater activity than approved EGFR TKIs in vitro and in EGFR or HER2 exon 20 mutant patient-derived xenograft models, and genetically engineered mouse models of NSCLC.

MD Anderson reported an interim Phase 2 analysis at the World Conference on Lung Cancer on September 24, 2018 in Toronto, Canada, as follows:

• In evaluable patients with EGFR exon 20 mutations, the confirmed overall response rate (ORR) was 43% and disease control rate was 90%. Median progression free survival (PFS) was 5.5 months (ITT).

• In evaluable patients with HER2 exon 20 mutations, the confirmed overall response rate (ORR) was 42% and disease control rate was 83%. Median progression free survival (PFS) was 5.1 months (ITT).

• EGFR-related toxicities (including rash, diarrhea, and paronychia) were manageable and required dose reductions in 60% of patients. Discontinuation due to poor tolerance was rare (approximately 3% of patients).

We submitted a request for Breakthrough Therapy Designation for poziotinib in previously treated metastatic NSCLC with EGFR exon 20 mutations and we expect a response from the FDA by the end of 2018. Our ZENITH20 trial is well underway and enrolling in four distinct cohorts.

• First-line cohorts in both EGFR and HER2 were initiated in the third quarter of 2018.

• Enrollment in the EGFR, previously treated cohort is expected to be completed by the first quarter of 2019.

poziotinib use in Treatment of Breast Cancer

We are also currently enrolling patients in a Phase 2 breast cancer trial for poziotinib. The Phase 2 study is an open-label study that will enroll approximately 75 patients with HER2 positive metastatic breast cancer, who have failed at least two HER2 directed therapies. Additionally, we have recently opened a Phase 1b study that will test the combination of poziotinib and ado-trastuzumab emtansine (T-DM1) in patients with metastatic breast cancer.

• ROLONTIS, a novel long-acting G-CSF:

A pivotal Phase 3 study (ADVANCE study, or SPI-GCF-301) was initiated to evaluate ROLONTIS as a treatment for chemotherapy-induced neutropenia. The ADVANCE study is being conducted under a special protocol assessment (“SPA”) with the FDA. On June 29, 2018, we announced that the ADVANCE study met the non-inferiority of ROLONTIS to pegfilgrastim endpoint in the Duration of Severe Neutropenia (“DSN”) across all 4 cycles (all p<0.0001). We initiated a second pivotal Phase 3 study (RECOVER study, or SPI-GCF-302), and as also announced on June 29, 2018, had met its primary efficacy endpoint of non-inferiority in DSN between ROLONTIS and pegfilgrastim.

We had a productive pre-Biologics License Application (“BLA”) meeting with the FDA for ROLONTIS and we expect to file our BLA in the fourth quarter of 2018.

Data from our RECOVER study will be presented in a poster session at the San Antonio Breast Cancer Symposium in early December 2018.

Total revenues	$	25.3	$	36.4	$	(11.1	)	(30.5	)%

Product sales, net. To derive net product sales, gross product revenues in each period are reduced by management’s latest estimated provisions for (i) product returns, (ii) government chargebacks, (iii) prompt pay discounts, (iv) commercial rebates, (v) Medicaid rebates, and (vi) distribution, data, and group purchasing organization (“GPO”), administrative fees. Our management considers various factors in the determination of these provisions, which are described within Note 2(i)(a) to our accompanying Condensed Consolidated Financial Statements.

FOLOTYN revenue decreased $0.3 million as a result of a decrease in the number of units sold, partially offset by an increase in the average net sales price per unit in the current period.

EVOMELA revenue decreased $3.6 million as a result of both the decrease in the number of units sold and our average net sales price per unit in the current period.

BELEODAQ revenue decreased $0.2 million as a result of a decrease in the number of units sold, partially offset by an increase in the net average sales price per unit in the current period.

ZEVALIN revenue decreased $1.2 million as a result of both the decrease in the number of units sold and our average net sales price per unit in the current period.

MARQIBO revenue decreased $0.1 million as a result of a decrease in the number of units sold, partially offset by an increase in our average net sales price per unit in the current period.

FUSILEV revenue decreased $1.2 million as a result of both the decrease in the number of units sold and our average net sales price per unit, due to the competitive generic levo-leucovorin products, beginning in April 2015 (see Note 3(f) to our accompanying Condensed Consolidated Financial Statements).

License fees and service revenue. Our license fees and service revenue in the current period decreased by $4.5 million. This is due to $5 million recognized in the prior-year period for contractual milestone achievements, related to the non-recurrence of $5 million of regulatory and commercial milestone achievements of our licensee within Japan (see Note 15(b)(vii) to our accompanying Condensed Consolidated Financial Statements). This decrease was partially offset by $0.6 million increase in royalties related to our out-license of FOLOTYN (see Note 14 to our accompanying Condensed Consolidated Financial Statements).

Total operating costs and expenses	$	54.3	$	51.4	$	2.9		5.6	%

Cost of Sales. Cost of sales decreased $5.7 million in the current period primarily due to our net product revenue decrease, as well as our product sales mix in each period.

Selling, General and Administrative. Selling, general and administrative expenses increased $1.3 million in the current period primarily due to increases in personnel-related and employee development costs to support our current operations and future growth.

Research and Development. Research and development expenses increased by $7.3 million in the current period due to a number of factors, including: (i) $3.5 million increase in clinical and development initiatives related to poziotinib; (ii) $1.3 million increase in manufacturing costs associated with KHAPZORY (see Note 20 to our accompanying Condensed Consolidated Financial Statements); (iii) $1.2 million increase of FDA validation costs for EVOMELA production; (iv) $0.5 million increase in our development of MARQIBO single-vial formulation; and (iv) $1.9 million increase in personnel-related costs to drive these product development initiatives. These increases were partially offset by a $0.9 million decrease in expenses associated with ROLONTIS, as both the ADVANCE and RECOVER clinical studies have completed enrollment and associated costs are down as compared to the prior year period.

Amortization of Intangible Assets. Amortization expense remained consistent compared to the prior year period.

Total other expense	$	(39.7	)	$	(4.7	)	$	(35.0	)	(744.7	)%

Total other expense. Total other expenseincreased by $35.0 million primarily due to $40.9 million increase in unrealized loss on our CASI Pharmaceuticals, Inc. equity securities, which are now recorded within “other (expense) income, net” rather than “other comprehensive (loss) income” due to our adoption of ASU 2016-01 (see Note 3(a) to our accompanying Condensed Consolidated Financial Statements). This increase was partially offset by (i) $4.1 million decrease in the fair value of contingent consideration related to our MARQIBO product (see Note 9(a) to our accompanying Condensed Consolidated Financial Statements), and (ii) $2 million decrease in interest expense on our 2.75% Convertible Senior Notes due December 2018 (the “2018 Convertible Notes”) as a result of our October 2017 repurchase of $69.5 million of principal value (see Note 13 to our accompanying Condensed Consolidated Financial Statements).

taxes” on our Condensed Consolidated Statements of Operations for the three months ended September 30, 2018. Due to a required intraperiod allocation of tax expense for the three months ended September 30, 2017 we recorded a benefit for income taxes of $1.5 million in continuing operations as a result of unrealized gains recognized in “other comprehensive (loss) income” on our Condensed Consolidated Statements of Comprehensive Loss. As a result of the unrealized gains, we recorded $2 million of tax expense within “other comprehensive (loss) income” on our Condensed Consolidated Statements of Comprehensive Loss for the three months ended September 30, 2017.

* Does not agree to the face of the accompanying Condensed Consolidated Statements of Operations for the nine months ended September 30, 2018 by an immaterial amount due to rounding.

Product sales, net. To derive net product sales, gross product revenues in each period are reduced by management’s latest estimated provisions for (i) product returns, (ii) government chargebacks, (iii) prompt pay discounts, (iv) commercial rebates, (v) Medicaid rebates, and (vi) distribution, data, and GPO administrative fees. Our management considers various factors in the determination of these provisions, which are described within Note 2(i)(a) to our accompanying Condensed Consolidated Financial Statements.

FOLOTYN revenue increased $3.7 million due to an increase in our average net sales price per unit, partially offset by a decrease in units sold during the period.

EVOMELA revenue decreased $6.1 million due to a decrease in our average net sales price per unit.

BELEODAQ revenue decreased $1.1 million due to a decrease in units sold during the period, partially offset by an increase in our average net sales price per unit.

ZEVALIN revenue decreased $1.8 million due to a decrease in units sold in the U.S. territory, partially offset by an increase in product sales to Mundipharma for end-users in Japan (see Note 11).

MARQIBO revenue decreased $2.2 million due to a decrease in units sold during the period, partially offset by an increase in our average net sales price per unit.

FUSILEV revenue decreased $4.4 million as a result of both the decrease in the number of units sold and our average net sales price per unit, due to the competitive generic levo-leucovorin products, beginning in April 2015 (see Note 3(f)) to our accompanying Condensed Consolidated Financial Statements).

License fees and service revenue. Our license fees and service revenue in the current period decreased by $8.1 million primarily due to the following: (i) $4 million decrease in FOLOTYN royalties, primarily related to the non-recurrence of $5 million of regulatory and commercial milestone achievements of our licensee within Japan (see Note 15(b)(vii) to our accompanying Condensed Consolidated Financial Statements); and (ii) $4.7 million of non-recurring service revenue from our expired co-promotion arrangement with Eagle Pharmaceuticals, Inc. (see Note 12 to our accompanying Condensed Consolidated Financial Statements), partially offset by a $0.8 million increase in ZEVALIN license fees.

Total operating costs and expenses	$	168.5	$	155.4	$	13.1		8.4	%

Cost of Sales. Cost of sales decreased $11.7 million in the current period primarily due to our net product revenue decrease, as well as our product sales mix in each period.

Cost of Service Revenue. Cost of service revenue relates to our allocated commercial and marketing expenses (from “selling, general, and administrative” expenses) for the fee-based promotion and sale of Eagle Pharmaceuticals, Inc.’s products by our sales force. Our cost of service revenue decreased by the full $4.2 million incurred in the prior period, as we ceased marketing these products as of July 1, 2017 (see Note 12 to our accompanying Condensed Consolidated Financial Statements).

Selling, General and Administrative. Selling, general and administrative expenses increased by $12.3 million in the current period primarily due to (i) the non-recurrence of certain sales and marketing costs in the prior period, aggregating $4.2 million, that were allocated from this account to “cost of service revenue” (see above); (ii) $3.2 million increase in personnel-related costs largely attributed to increased stock-based compensation expense of $2.1 million, and $1.0 million of Nevada payroll tax expense related to stock option exercises by our former chief executive officer; (iii) $3 million increase in litigation expenses primarily associated with the termination of our former chief executive officer in December 2017; (iv) $1.2 million increase in consulting expenses, given our key initiatives, including the expected commercial launch of ROLONTIS in late 2019, and our ongoing clinical trials for poziotinib; and (v) $0.7 million increase in various other costs to support our current operations and planned growth.

Research and Development. Research and development expenses increased by $16.6 million in the current period due to a number of factors, including (i) $11.4 million increase in clinical and development initiatives largely related to poziotinib; (ii) $3.8 million increase in personnel-related costs to drive our product development; (iii) $2.8 million increase in the development of KHAPZORY (primarily due to a $1.2 million FDA filing fee for its NDA, a corresponding $0.3 million milestone payment to a licensor, and associated manufacturing costs) (see Note 20 our accompanying Condensed Consolidated Financial Statements); (iv) $0.8 million in technical transfer costs associated with ZEVALIN production; and (v) $0.6 million increase in new contract manufacturer validation for EVOMELA. These increases were partially offset by a $3.3 million decrease in clinical trial expenses associated with ROLONTIS, as both the ADVANCE and RECOVER studies have completed enrollment and associated costs are significantly reduced as compared to the prior year period.

Amortization and Impairment Charges of Intangible Assets. Amortization expense remained consistent compared to the prior year period.

Total other income (expense)	$	17.8	$	(8.5	)	$	26.3	309.4	%

Total other income (expense). Total other income (expense)increased by $26.3 million primarily due to (i) $17.7 million increase in unrealized gain on our CASI Pharmaceuticals, Inc. equity securities, which are now recorded within “other (expense) income, net” rather than “other comprehensive (loss) income” due to our adoption of ASU 2016-01 (see Note 3(a) to our accompanying Condensed Consolidated Financial Statements); (ii) $5.7 million decrease in interest expense primarily due to our 2018 Convertible Notes as a result of our October 2017 repurchase of $69.5 million of principal value (see Note 13 to our

46

accompanying Condensed Consolidated Financial Statements); and (iii) $3.9 million decrease in the fair value of contingent consideration related to our MARQIBO product (see Note 9(b) to our accompanying Condensed Consolidated Financial Statements), partially offset by $0.9 million increase in executive deferred compensation as a result of decreases in fair value of corresponding plan assets (see Note 15(f) to our accompanying Condensed Consolidated Financial Statements).

(Provision) benefit for income taxes	$	—	$	1.4	$	(1.4	)	100.0	%

Our provision for income taxes of $8 thousand for the nine months ended September 30, 2018, is primarily due to increases in our deferred tax liabilities associated with indefinite lived assets which in turn result in an increased valuation allowance on our deferred tax assets. For the nine months ended September 30, 2017 we recorded a benefit for income taxes of $1.4 million within our Condensed Consolidated Statements of Operations due to a required intraperiod allocation of tax expense, resulting in unrealized gains within “other comprehensive (loss) income” on our Condensed Consolidated Statements of Comprehensive Loss. As a result of the unrealized gains, we recorded $2 million of tax expense within “other comprehensive (loss) income” on our Condensed Consolidated Statements of Comprehensive Loss for the nine months ended September 30, 2017.

Net Cash Used In Operating Activities

Net cash used in operating activities was $50.1 million for the nine months ended September 30, 2018, as compared to $26 million in the prior year period. For the nine months ended September 30, 2018 and 2017, our cash collections from customers totaled $91.9 million and $119.1 million, respectively, representing 115.0% and 121.8% of reported net revenue for the same nine-month periods. For the nine months ended September 30, 2018 and 2017, cash payments for products, services, chargebacks, and rebates to our employees, vendors, and product end-users totaled $153.5 million and $149.7 million, respectively.

Net Cash Provided by (Used In) Investing Activities

Net cash provided by investing activities was $4.1 million for the nine months ended September 30, 2018, as compared to $1 million of cash used in investing activities during the prior year period. The cash provided by investing activities for the nine months of 2018 primarily relates to $4.1 million of proceeds received from the redemption of our corporate-owned life insurance policy.

Net Cash (Used In) Provided by Financing Activities

47

Net cash used in financing activities was $14.5 million for the nine months ended September 30, 2018, as compared to $115.9 million provided by financing activities in the prior year period. Our cash used in financing activities during the first nine months of 2018 primarily relates to our $27.7 million of aggregate payments to federal and state tax authorities related to our employees’ tax liabilities at the time of stock vestings and exercises. We made these payments in return for an equivalent value of surrendered shares by our employees. This outflow was partially offset by: (i) $4.6 million of proceeds received from employees related to remittances to federal and state tax authorities for taxes due at vesting/exercise of equity awards, (ii) $7.8 million of proceeds as a result of the exercise of employee stock options, and (iii) $0.7 million of proceeds from the sale of equity under our employee stock purchase plan.

2018 Convertible Notes

In December 2013, we entered into an agreement for the sale of our 2018 Convertible Notes in the aggregate amount of $120 million. The 2018 Convertible Notes bear interest at a rate of 2.75% per year, payable semiannually in arrears on June 15 and December 15 of each year. The 2018 Convertible Notes will mature and become payable on December 15, 2018, subject to earlier conversion into common stock at the holders’ option. As of September 30, 2018 and December 31, 2017, an aggregate amount of $35.8 million and $40.6 million of principal of the 2018 Convertible Notes remained outstanding, respectively, due to our open market purchases of these instruments in December 2016 and October 2017, as well as $4.7 million of principal value, converted by a holder in July 2018 into 451,300 common shares (see Note 13 to our accompanying Condensed Consolidated Financial Statements).

The 2018 Convertible Notes are convertible into shares of our common stock at a current conversion rate of 95 shares per $1,000 principal amount of the 2018 Convertible Notes, or a conversion price of approximately $10.53 per common share. Our stockholders’ approved “flexible settlement” at our Annual Meeting of Stockholders on June 29, 2015, though on September 27, 2018, we elected to exclusively settle any and all conversions with our common stock. As a result, a maximum of approximately 3.4 million common shares would have been issued if the 2018 Convertible Notes had been converted in full on September 30, 2018. If the holders of our 2018 Convertible Notes do not elect to convert, our December 2018 obligation to repay the remaining principal amount of $35.8 million in cash, plus any accrued and unpaid interest, will remain unchanged.

Sale of Common Stock Under ATM Agreements

In December 2015 and August 2017, we entered into collective at-market-issuance sales agreements with FBR Capital Markets & Co., MLV & Co. LLC, and H.C. Wainwright & Co., LLC. These agreements allowed us to raise aggregate gross proceeds through these brokers of up to $250 million from the sale of our common stock on the public market.

Through September 30, 2018, we had raised aggregate gross net proceeds of $202.1 million through these at-market sales, of which $128.3 million was raised during the year ended December 31, 2017. We had no sales under the ATM during the nine months ended September 30, 2018. We are using these proceeds to continue to develop our product pipeline and to provide additional capital structure flexibility.

Future Capital Requirements

We believe that the future growth of our business will depend on our ability to successfully develop and acquire new drugs for the treatment of cancer and successfully bring these drugs to market.

The timing and amount of our future capital requirements will depend on many factors, including:

• the need for additional capital to fund future development programs;

• the need for additional capital to fund strategic acquisitions;

• the need for additional capital to fund licensing arrangements;

• our requirement for additional information technology infrastructure and systems; and

• adverse outcomes from potential litigation and the cost to defend such litigation.

We believe that our $221 million in aggregate cash and equivalents and marketable securities as of September 30, 2018 will allow us to fund our current and planned operations into 2020. However, we may seek 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 on terms favorable to us or our current stockholders and convertible senior note holders, if at all.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements (except for operating leases) that provide financing, liquidity, market or credit risk support, or involve derivatives. In addition, we have no arrangements that may expose us to liability that are not expressly reflected in the accompanying Condensed Consolidated Financial Statements and/or notes thereto.

As of September 30, 2018, we did not have any relationships with unconsolidated entities or financial partnerships, often referred to as “structured finance” or “special purpose entities,” established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not subject to any material financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

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, credit ratings and foreign currency exchange rates.

The primary objective of our investment activities is to preserve principal, while at the same time maximizing yields without significantly increasing risk. We do not utilize hedging contracts or similar instruments, except with respect to the 2018 Convertible Notes (see Note 13 to our accompanying Condensed Consolidated Financial Statements). Because of our ability to generally redeem these investments at par at short notice and without penalty, 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 September 30, 2018, any decline in the fair value of our investments would not be material in the context of our accompanying 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.

We are exposed to foreign currency exchange rate fluctuations relating to payments we make to vendors, suppliers and license partners in Euros (and other currencies to a lesser extent). We mitigate such risk by maintaining a limited portion of our cash in Euros.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2018. 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 SEC’s rules and forms. These include controls and procedures 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 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.

Based on the evaluation of our disclosure controls and procedures as of September 30, 2018, our chief executive officer and chief financial officer concluded that, as of that date, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the third fiscal quarter of 2018 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 continuously seek to improve the efficiency and effectiveness of our operations and of our internal controls.

PART II. OTHER INFORMATION

49

ITEM 1.    LEGAL PROCEEDINGS

We are involved from time-to-time with various legal matters arising in the ordinary course of business. These claims and legal proceedings are of a nature we believe are normal and incidental to a pharmaceutical business, and may include product liability, intellectual property, employment matters, and other general claims. We may also be subject to derivative lawsuits from time to time.

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 assessed 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 consolidated results of operations, cash flows, or financial condition.

Certain of the legal proceedings in which we are involved are discussed in Note 15, “Financial Commitments & Contingencies and License Agreements,” to our accompanying Condensed Consolidated Financial Statements, and are hereby incorporated by reference.

ITEM 1A.    RISK FACTORS

As of the date of this filing, there have been no material changes to the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC on March 7, 2018.

Exhibit 10.1

AMENDED AND RESTATED

SPECTRUM PHARMACEUTICALS, INC.2009 EMPLOYEE STOCK PURCHASE PLAN

This EMPLOYEE STOCK PURCHASE PLAN (the “Plan”) is hereby established by Spectrum Pharmaceuticals, Inc., a Delaware corporation (the “Company”) as of March 23, 2009. The Plan was amended and restated as of September 21, 2018.

ARTICLE IPURPOSE OF THE PLAN

1.1Purpose. The Company has determined that it is in its best interests to provide an incentive to attract and retain employees and to increase employee morale by providing a program through which employees may acquire a proprietary interest in the Company through the purchase of shares of the common stock of the Company (“Company Stock”). The Plan is hereby established by the Company to permit employees to subscribe for and purchase directly from the Company shares of the Company Stock at a discount from the market price, and to pay the purchase price in installments by payroll deductions. The Plan is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”). The provisions of the Plan are to be construed in a manner consistent with the requirements of Section 423 of the Code. The Plan is not intended to be an employee benefit plan under the Employee Retirement Income Security Act of 1974, and therefore is not required to comply with that Act.

ARTICLE IIDEFINITIONS

2.1Compensation. “Compensation” means the (i) regular base salary paid to a Participant by the Company during such individual’s period of participation in one or more Offering Periods under the Plan before (ii) any pre-tax contributions made by the Participant to any Code Section 401(k) salary deferral plan or any Code Section 125 cafeteria benefit program now or hereafter established by the Company or any of its affiliates. The following items of compensation shall be included in Compensation: all (i) overtime payments, commissions that function as base salary equivalents, vacation and sick leave compensation and bonuses. The following items of compensation shall not be included in Compensation: (i) commissions that do not function as base salary equivalents, (ii) profit-sharing distributions (iii) incentive compensation and incentive payments and (iv) any and all contributions (other than Code Section 401(k) or Code Section 125 contributions) made on the Participant’s behalf by the Company or any of its affiliates under any employee benefit or welfare plan now or hereafter established.

2.2Employee. “Employee” means each person currently employed by the Company or any of its operating subsidiaries, any portion of whose income is subject to withholding of income tax or for whom Social Security retirement contributions are made by the Company or any of its operating subsidiaries.

2.35% Owner. “5% Owner” means an Employee who, immediately after the grant of any rights under the Plan, would own Company Stock or hold outstanding options to purchase Company Stock possessing 5% or more of the total combined voting power of all classes of stock of the Company. For purposes of this Section, the ownership attribution rules of Code Section 425(d) shall apply.

2.4Offering Date. “Offering Date” means the first day of each Offering Period under the Plan. For the first Offering Period, the Offering Date shall be July 1, 2009.

2.5Participant. “Participant” means an Employee who has satisfied the eligibility requirements of Section 3.1 and has become a participant in the Plan in accordance with Section 3.2.

2.6Plan Year. “Plan Year” means the twelve consecutive month period ending on December 31.

2.8Purchase Date. “Purchase Date” means the last day of each Offering Period.

ARTICLE IIIELIGIBILITY AND PARTICIPATION

3.1Eligibility. Each Employee of the Company or any of its operating subsidiaries designated from time to time by the Administrator, who may become a Participant in the Plan on the Offering Date coincident with or next following his satisfaction of such requirements of employment with the Company or any of its operating subsidiaries. The Administrator may exclude from participation those persons allowed to be excluded pursuant to Code Section 423, provided that such exclusions shall apply to all employees who meet the exclusion criteria. The Administrator may provide that Employees who are “highly compensated employees” within the meaning of Section 423(b)(4)(D) of the Code are not eligible to participate in the Plan.

3.2Participation. An Employee who has satisfied the eligibility requirements of Section 3.1 may become a Participant in the Plan upon his or her completion and delivery to the Human Resources Department of the Company of a subscription agreement provided by the Company (the “Subscription Agreement”) authorizing payroll deductions. Payroll deductions for a Participant shall commence on the Offering Date coincident with or next following the filing of the Participant’s Subscription Agreement and shall remain in effect until revoked by the Participant by the filing of a notice of withdrawal from the Plan under Article VIII or by the filing of a new Subscription Agreement providing for a change in the Participant’s payroll deduction rate under Section 5.2.

3.3Special Rules. Under no circumstances shall:

(a)    A 5% Owner be granted a right to purchase Company Stock under the Plan; or

(b)    A Participant be entitled to purchase Company Stock under the Plan which, when aggregated with all other employee stock purchase plans of the Company, exceeds an amount equal to the Aggregate Maximum. “Aggregate Maximum” means an amount equal to twenty-five thousand dollars ($25,000) worth of Company Stock (determined using the fair market value of such Company Stock at each applicable Offering Date) during each Plan Year.

(c)    The number of shares of Company Stock purchasable by a Participant on any Purchase Date exceed 50,000 shares, subject to necessary adjustments under Section 10.4.

ARTICLE IV
OFFERING PERIODS

The initial grant of the right to purchase Company Stock under the Plan shall commence on July 1, 2009 and terminate on the next Purchase Date. Thereafter, the Plan shall provide for Offering Periods commencing on each Offering Date and terminating on the next following Purchase Date.

ARTICLE VPAYROLL DEDUCTIONS

5.1Participant Election. Each Participant shall designate, in a subscription agreement, the amount of payroll deductions to be made from his or her paycheck to purchase Company Stock under the Plan. The amount so designated within the Subscription Agreement shall be effective as of the next Offering Date and shall continue until terminated or altered in accordance with Section 5.2 below.

5.2Changes in Election. A Participant may terminate participation in the Plan at any time prior to the close of an Offering Period as provided in Article VIII. A Participant may decrease or increase the rate of payroll deductions at any time during any Offering Period by completing and delivering to the Human Resources Department of the Company a new Subscription Agreement setting forth the desired change. A Participant may also terminate payroll deductions and have accumulated deductions for the Offering Period up to the date of termination applied to the purchase of Company Stock as of the next Purchase Date by completing and delivering to the Human Resources Department a new Subscription Agreement setting forth the desired change. Any change under this Section shall become effective on the next payroll period (to the extent practical under the Company’s payroll practices) following the delivery of the new Subscription Agreement.

5.3Participant Accounts. The Company shall establish and maintain a separate journal account (“Account”) for each Participant. The amount of each Participant’s payroll deductions shall be credited to his or her Account. No interest will be paid or allowed on amounts credited to a Participant’s Account. All payroll deductions received by the Company under the Plan are general corporate assets of the Company and may be used by the Company for any corporate purpose. The Company is not obligated to segregate such payroll deductions.

ARTICLE VIGRANT OF PURCHASE RIGHTS

6.1Right to Purchase Shares. On each Offering Date, each Participant shall be granted a right to purchase at the price determined under Section 6.2 that number of whole shares of Company Stock that can be purchased or issued by the Company based upon that price with the amounts held in his or her Account, subject to the limits set forth in Section 3.3.

6.2Purchase Price. The purchase price for any Offering Period shall be the lesser of:

(a)    85% of the Fair Market Value of Company Stock on the Offering Date; or

(b)    85% of the Fair Market Value of Company Stock on the Purchase Date.

6.3Fair Market Value. “Fair Market Value” means the value of one share of Company Stock, determined as follows:

(a)    If the Company Stock is then listed or admitted to trading on a stock exchange which reports closing sale prices, the Fair Market Value shall be the closing sale price on the date of valuation on the principal stock exchange on which the Company Stock is then listed or admitted to trading, or, if no closing sale price is quoted or no sale takes place on such day, then the Fair Market Value shall be the closing sale price of the Company Stock on such exchange on the immediately preceding day on which a sale occurred.

(b)    If the Company Stock is not then listed or admitted to trading on a stock exchange which reports closing sale prices, the Fair Market Value shall be the average of the closing bid and asked prices of the Company Stock in the over-the-counter market on the date of valuation.

(c)    If neither (a) nor (b) is applicable as of the date of valuation, then the Fair Market Value shall be determined by the Administrator (defined in Section 9.1(a) below) in good faith using any reasonable method of valuation, which determination shall be conclusive and binding on all interested parties.

ARTICLE VIIPURCHASE OF STOCK

7.1Purchase of Company Stock. Absent an election by the Participant to terminate and have his or her Account returned, on each Purchase Date, the Plan shall purchase on behalf of each Participant the maximum number of whole shares of Company Stock at the purchase price determined under Section 6.2 above as can be purchased with the amounts held in each Participant’s Account. The Plan shall not be required to purchase any fractional shares of Company Stock. In the event that there are amounts held in a Participant’s Account that are not used to purchase Company Stock, all such amounts shall be held in the Participant’s Account and carried forward to the next Offering Period, or may be returned to the Participant at his or her election.

7.2Delivery of Company Stock.

(a)    Company Stock acquired under the Plan may either be issued directly to Participants or may be issued to a contract administrator (the “Agent”) engaged by the Administrator under Article IX to carry out responsibilities under the Plan. If the Company Stock is issued in the name of the Agent, all Company Stock so issued (“Plan Held Stock”) shall be held in the name of the Agent for the benefit of the Plan. The Agent shall maintain accounts for the benefit of the Participants which shall reflect each Participant’s interest in the Plan Held Stock. Such accounts shall reflect the number of shares of Company Stock that are being held by the Agent for the benefit of each Participant.

(b)    Any Participant may elect to have the Company Stock purchased under the Plan from his or her Account be issued directly to the Participant. Any election under this paragraph shall be on the forms provided by the Company and shall be issued in accordance with paragraph (c) below.

(c)    In the event that Company Stock under the Plan is issued directly to a Participant, the Company will deliver to each Participant a number of shares of Company Stock purchased promptly after the Purchase Date. Shares shall be delivered either in certificated form, or otherwise, as elected by the Company in the exercise of its reasonable discretion and subject to applicable law. The time of issuance and delivery of shares may be postponed for such period as may be necessary to comply with the registration requirements under the Securities Act of 1933, as amended, the listing requirements of any securities exchange on which the Company Stock may then be listed, or the requirements under other laws or regulations applicable to the issuance or sale of such shares.

ARTICLE VIIIWITHDRAWAL

8.1In Service Withdrawals. At any time prior to the Purchase Date of an Offering Period, any Participant may withdraw the amounts held in his Account by executing and delivering to the Human Resources Department for the Company written notice of withdrawal on the form provided by the Company. In such a case, the entire balance of the Participant’s Account shall be paid to the Participant, without interest, as soon as is practicable. Upon such notification, the Participant shall not participate in the Plan for the remainder of the Offering Period in which the notice is given, but may then be reinstated as a Participant for a subsequent Offering Period by executing and delivering a new Subscription Agreement to the Company.

8.2Termination of Employment.

(a)    In the event that a Participant’s employment with the Company terminates for any reason, or ceases to be eligible under Section 3.1, the Participant shall cease to participate in the Plan on the date of termination. As soon as is practical following the date of termination, the entire balance of the Participant’s Account shall be paid to the Participant or his beneficiary, without interest.

(b)    A Participant may file a written designation of a beneficiary who is to receive any shares of Company Stock purchased under the Plan or any cash from the Participant’s Account in the event of his or her

death subsequent to a Purchase Date, but prior to delivery of such shares and cash. In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s Account under the Plan in the event of his death prior to a Purchase Date under paragraph (a) above.

(c)    Any beneficiary designation under paragraph (b) above may be changed by the Participant at any time by written notice. In the event of the death of a Participant, the Company may rely upon the most recent beneficiary designation it has on file as being the appropriate beneficiary. In the event of the death of a Participant, and no valid beneficiary designation exists or the beneficiary has predeceased the Participant, the Company shall deliver any cash or shares of Company Stock to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed to the knowledge of the Company, the Company, in its sole discretion, may deliver such shares of Company Stock or cash to the spouse or any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

ARTICLE IX
PLAN ADMINISTRATION.

9.1Plan Administration.

(a)    Authority to control and manage the operation and administration of the Plan shall be vested in the Board of Directors of the Company, or a committee thereof (herein referred to as the “Administrator”). The Administrator shall have all powers necessary to supervise the administration of the Plan and control its operations.

(b)    In addition to any powers and authority conferred on the Administrator elsewhere in the Plan or by law, the Administrator shall have the following powers and authority:

(i)    To determine when and how rights to purchase common stock are granted and the terms and conditions of each offering;

(ii)    To designate from time to time which of the Company’s designated subsidiaries are eligible to participate in the Plan;

(iii)    To construe and interpret the Plan and the rights offered under the Plan;

(iv)    To establish, amend and revoke rules and regulations for the administration of the Plan;

(v)    To amend, suspend or terminate the Plan; provided, however that the Administrator may not amend the Plan to either increase the number of shares that may be purchased under the Plan or to change the designation or class of Employees eligible to participate in the Plan without obtaining stockholder approval within 12 months before or after such action if such approval is required by applicable laws, codes, or regulations; and

(vi)    To exercise such other powers and perform such other acts deemed necessary to carry out the intent of the Plan.

(c)    Any action taken in good faith by the Administrator in the exercise of authority conferred upon it by this Plan shall be conclusive and binding upon a Participant and his or her beneficiaries. All discretionary powers conferred upon the Administrator shall be absolute.

9.2Limitation on Liability. No Employee of the Company or member of the Administrator shall be subject to any liability with respect to his duties under the Plan unless the person acts fraudulently or in bad faith. To the extent permitted by law, the Company shall indemnify each member of the Administrator, and any other Employee of the Company with duties under the Plan who was or is a party, or is threatened to be made a

party, to any threatened, pending or completed proceeding, whether civil, criminal, administrative, or investigative, by reason of the person’s conduct in the performance of his duties under the Plan.

ARTICLE XCOMPANY STOCK

10.1Limitations on Purchase of Shares. The maximum number of shares of Company Stock that shall be made available for future sale under the Plan shall be Five Million (5,000,000) shares plus an annual increase to be added on January 1 of each calender year beginning January 1, 2010 equal to the lesser of (i) 1,000,000 shares or (ii) an amount determined by the Administrator. Provided however, that in no event should the number of shares of Company Stock available for future sale under the 2009 ESPP exceed 10,000,000. The shares of Company Stock to be sold to Participants under the Plan will be either purchased in broker’s transactions in accordance with the requirements of federal securities laws or issued by the Company. If the total number of shares of Company Stock that would otherwise be issuable or purchasable pursuant to rights granted pursuant to Section 6.1 of the Plan at the Purchase Date exceeds the number of shares then available under the Plan, the Company shall make a pro rata allocation of the shares remaining available in as uniform and equitable a manner as is practicable. In such event, the Company shall give written notice of such reduction of the number of shares to each participant affected thereby and any unused payroll deductions shall be returned to such participant if necessary.

10.2Voting Company Stock. The Participant will have no interest or voting right in shares to be purchased under Section 6.1 of the Plan until such shares have been purchased.

10.3Registration of Company Stock. Shares to be delivered to a Participant under the Plan will be registered in the name of the Participant unless designated otherwise by the Participant.

10.4Changes in Capitalization of the Company. Subject to any required action by the stockholders of the Company, the number of shares of Company Stock covered by each right under the Plan which has not yet been exercised and the number of shares of Company Stock which have been authorized for issuance under the Plan but have not yet been placed under rights or which have been returned to the Plan upon the cancellation of a right, as well as the Purchase Price per share of Company Stock covered by each right under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Company Stock resulting from a stock split, stock dividend, spin-off, reorganization, recapitalization, merger, consolidation, exchange of shares or the like. Such adjustment shall be made by the Board of Directors of the Company, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Company Stock subject to any right granted hereunder.

10.5Merger, Liquidation or Dissolution of Company. In the event of: (1) the Company’s dissolution or liquidation, (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the shares of common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) the acquisition by any person, entity or group of the beneficial ownership of the Company’s securities representing at least 50% of the combined voting power entitled to vote in the election of directors, then, as determined by the Administrator in its sole discretion (i) any surviving or acquiring corporation may assume outstanding rights or substitute similar rights for those under the Plan, (ii) such rights may continue in full force and effect, or (iii) Participants’ accumulated payroll deductions may be used to purchase common stock immediately prior to the transaction described above (at a Purchase Date to be chosen solely by the Administrator) and the Participants’ rights under the ongoing offering period are terminated.

ARTICLE XIMISCELLANEOUS MATTERS

11.1Amendment and Termination. The Plan will become effective upon the later to occur of its adoption by the Board or its approval by the stockholders of the Company. Since future conditions affecting the Company cannot be anticipated or foreseen, the Company reserves the right to amend, modify, or terminate the Plan at any time. Upon termination of the Plan, all benefits shall become payable immediately. Notwithstanding the foregoing, no such amendment or termination shall affect rights previously granted, nor may an amendment make any change in any right previously granted which adversely affects the rights of any Participant. In addition, to the extent required by applicable laws, codes or regulations, no amendment may be made without obtaining stockholder approval within 12 months before or after such action if such amendment would,

(a)    Increase the number of shares of Company Stock that may be issued under the Plan; or

(b)    Change the designation or class of employees eligible to participate in the Plan.

11.2Stockholder Approval. Continuance of the Plan and the effectiveness of any right granted hereunder shall be subject to approval by the stockholders of the Company, within twelve months before or after the date the Plan is adopted by the Board of Directors of the Company.

11.3Benefits Not Alienable. Rights and benefits under the Plan may not be assigned or alienated, whether voluntarily or involuntarily. Any attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Article VIII.

11.4No Enlargement of Employee Rights. This Plan is strictly a voluntary undertaking on the part of the Company and shall not be deemed to constitute a contract between the Company and any Employee or to be consideration for, or an inducement to, or a condition of, the employment of any Employee. Nothing contained in the Plan shall be deemed to give the right to any Employee to be retained in the employ of the Company or to interfere with the right of the Company to discharge any Employee at any time.

11.5Governing Law. To the extent not preempted by Federal law, all legal questions pertaining to the Plan shall be determined in accordance with the laws of the State of California without regard for conflicts of laws principles.

11.6Non-business Days. When any act under the Plan is required to be performed on a day that falls on a Saturday, Sunday or legal holiday, that act shall be performed on the next succeeding day which is not a Saturday, Sunday or legal holiday. Notwithstanding the above, Fair Market Value shall be determined in accordance with Section 6.3.

11.7Compliance With Securities Laws. Notwithstanding any provision of the Plan, the Administrator shall administer the Plan in such a way to insure that the Plan at all times complies with any requirements of Federal Securities Laws. For example, affiliates may be required to make irrevocable elections in accordance with the rules set forth under Section 16b-3 of the Securities Exchange Act of 1934.

Description of Business, Basis of Presentation, and Operating Segment

DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION, AND OPERATING SEGMENT

(a) Description of Business

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biopharma company, with a primary strategy comprised of acquiring, developing, and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. We have an in-house clinical development organization with regulatory and data management capabilities, in addition to commercial infrastructure and a field-based sales force for our marketed products. Currently, we have six approved oncology/hematology products (FUSILEV, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA) that target different types of cancer including: non-Hodgkin’s lymphoma (“NHL”), advanced metastatic colorectal cancer, acute lymphoblastic leukemia, and multiple myeloma (“MM”).

We also have two drugs in mid-to-late stage development (in Phase 2 or Phase 3 clinical trials):

• poziotinib, a novel pan-HER inhibitor used in the treatment of patients with a variety of solid tumors, including breast and lung cancer; and

• ROLONTIS for chemotherapy-induced neutropenia.

(b) Basis of Presentation

Interim Financial Statements

The interim financial data for the three and nine months ended September 30, 2018 and 2017, respectively, is unaudited, and is not necessarily indicative of our operating results for a full year. In the opinion of our management, the interim data includes normal and recurring adjustments necessary for a fair presentation of our financial results for the three and nine months ended September 30, 2018 and 2017. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the U.S. Securities and Exchange Commission (“SEC”) rules and regulations relating to interim financial statements. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements and Notes thereto included within our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (filed with the SEC on March 7, 2018).

Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and with the rules and regulations of the SEC. These financial statements include the financial position, results of operations, and cash flows of Spectrum and its subsidiaries, all of which are wholly-owned (except for Spectrum Pharma Canada (“SPC”), as discussed below). All inter-company accounts and transactions among these legal entities have been eliminated in consolidation.

Variable Interest Entity

We own fifty-percent of SPC, a legal entity organized in Quebec, Canada in January 2008. Some of our clinical studies are conducted through this “variable interest entity” (as defined under applicable GAAP). We fund all of SPC’s operating costs, and since we assume all risks and rewards for this entity, we meet the criteria as being its “primary beneficiary” (as defined under applicable GAAP). Accordingly, SPC’s balance sheets and statements of operations are included in our Condensed Consolidated Financial Statements as if it were a wholly-owned subsidiary for all periods presented.

(c) Operating Segment

We operate in one reportable operating segment that is focused exclusively on developing and marketing oncology and hematology drug products. For the three and nine months ended September 30, 2018 and 2017, all of our revenue and related expenses were solely attributable to these activities. Substantially all of our assets (excluding cash held in certain foreign bank accounts and ZEVALIN distribution rights for ex-U.S. territories - see Note 3(f)) are held in the U.S.

Use of Estimates and Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Use of Estimates and Summary of Significant Accounting Policies

USE OF ESTIMATES AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in conformity with GAAP requires our management to make informed estimates and assumptions that affect our reported amounts of assets, liabilities, revenues, and expenses. These amounts may materially differ from the amounts ultimately realized and reported due to the inherent uncertainty of any estimate or assumption. On an on-going basis, our management evaluates its most critical estimates and assumptions, including those related to: (i) gross-to-net revenue adjustments; (ii) the timing of revenue recognition; (iii) the collectability of customer accounts; (iv) whether the cost of our inventories can be recovered; (v) the recoverability of our reported goodwill and intangible assets; (vi) the realization of our tax assets and estimates of our tax liabilities; (vii) the likelihood of payment and value of contingent liabilities; (viii) the fair value of our investments; (ix) the valuation of our stock options and the periodic expense recognition of stock-based compensation; and (x) the potential outcome of our ongoing or threatened litigation.

Our accounting policies and estimates that most significantly impact the presented amounts within our Condensed Consolidated Financial Statements are further described below:

(i) Revenue Recognition

Impact of the Adoption of the New Revenue Recognition Standard:ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for us on January 1, 2018. Our disclosure within the below sections to this footnote reflects our updated accounting policies that are affected by this new standard. We applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606; thisresulted in the recognition of an aggregate $4.7 million, net of tax, decrease to our January 1, 2018 “accumulated deficit” on our accompanying Condensed Consolidated Balance Sheets for the cumulative impact of applying this new standard. We made no adjustments to our previously-reported total revenues, as those periods continue to be presented in accordance with our historical accounting practices under Topic 605, Revenue Recognition (“Topic 605”). See Notes 4, 5, and 19 for additional quantitative and qualitative revenue disclosures in accordance with Topic 606.

Required Elements of Our Revenue Recognition: Revenue from our (a) product sales, (b) out-license arrangements, and (c) service arrangements is recognized under Topic 606 in a manner that reasonably reflects the delivery of our goods and/or services to customers in return for expected consideration and includes the following elements:

(1) we ensure that we have an executed contract(s) with our customer that we believe is legally enforceable;

(2) we identify the “performance obligations” in the respective contract;

(3) we determine the “transaction price” for each performance obligation in the respective contract;

(4) we allocate the transaction price to each performance obligation; and

(5) we recognize revenue only when we satisfy each performance obligation.

    These five elements, as applied to each of our revenue categories, are summarized below:

(a) Product Sales: We sell our products to pharmaceutical wholesalers/distributors (i.e., our customers), except for our U.S. sales of ZEVALIN in which case the end-user (i.e., clinic or hospital) is our customer. Our wholesalers/distributors in turn sell our products directly to clinics, hospitals, and private oncology-based practices. Revenue from our product sales is recognized as physical delivery of product occurs (when our customer obtains control of the product), in return for agreed-upon consideration.

Our gross product sales (i.e., delivered units multiplied by the contractual price per unit) are reduced by our corresponding gross-to-net (“GTN”) estimates using the “expected value” method, resulting in our reported “product sales, net” in the accompanying Condensed Consolidated Statements of Operations, reflecting the amount we ultimately expect to realize in net cash proceeds, taking into account our current period gross sales and related cash receipts, and the subsequent cash disbursements on these sales that we estimate for the various GTN categories discussed below. These estimates are based upon information received from external sources (such as written or oral information obtained from our customers with respect to their period-end inventory levels and sales to end-users during the period), in combination with management’s informed judgments. Due to the inherent uncertainty of these estimates, the actual amount incurred (of some, or all) of product returns, government chargebacks, prompt pay discounts, commercial rebates, Medicaid rebates, and distribution, data, and GPO administrative fees may be materially above or below the amount estimated, then requiring prospective adjustments to our reported net product sales.

These GTN estimate categories are each discussed below:

Product Returns Allowances: Our FUSILEV, MARQIBO, and BELEODAQ customers are contractually permitted to return purchased products beginning at its expiration date and within six months thereafter. Our EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months thereafter (as well as for overstock inventory, as determined by end-users). ZEVALIN and FOLOTYN returns for expiry are not contractually permitted. Returns outside of this aforementioned criteria are not customarily allowed. We estimate expected product returns for our allowance based on our historical return rates. Returned product is typically destroyed, since substantially all returns are due to expiry and cannot be resold.

Government Chargebacks: Our products are subject to pricing limits under certain federal government programs (e.g., Medicare and 340B Drug Pricing Program). Qualifying entities (i.e., end-users) purchase products from our customers at their qualifying discounted price. The chargeback amount we incur represents the difference between our contractual sales price to our customer, and the end-user’s applicable discounted purchase price under the government program. There may be significant lag time between our reported net product sales and our receipt of the corresponding government chargeback claims from our customers.

Prompt Pay Discounts: Discounts for prompt payment are estimated at the time of sale, based on our eligible customers’ prompt payment history and the contractual discount percentage.

Commercial Rebates: Commercial rebates are based on (i) our estimates of end-user purchases through a group purchasing organization (“GPO”), (ii) the corresponding contractual rebate percentage tier we expect each GPO to achieve, and (iii) our estimates of the impact of any prospective rebate program changes made by us.

Medicaid Rebates: Our products are subject to state government-managed Medicaid programs, whereby rebates are issued to participating state governments. These rebates arise when a patient treated with our product is covered under Medicaid, resulting in a discounted price for our product under the applicable Medicaid program. Our Medicaid rebate accrual calculations require us to project the magnitude of our sales, by state, that will be subject to these rebates. There is a significant time lag in us receiving rebate notices from each state (generally several months or longer after our sale is recognized). Our estimates are based on our historical claim levels by state, as supplemented by management’s judgment.

Distribution, Data, and GPO Administrative Fees: Distribution, data, and GPO administrative fees are paid to authorized wholesalers/distributors of our products (except for U.S. sales of ZEVALIN) for various commercial services including: contract administration, inventory management, delivery of end-user sales data, and product returns processing. These fees are based on a contractually-determined percentage of our applicable sales.

(b) License Fees: Our out-license arrangements allow licensees to market our product(s) in certain territories for a specific term (representing the out-license of “functional intellectual property”). These arrangements may include one or more of the following forms of consideration: (i) upfront license fees, (ii) sales royalties, (iii) sales milestone-achievement fees, and (iv) regulatory milestone-achievement fees. We recognize revenue for each based on the contractual terms that establish our right to collect payment once the performance obligation is achieved, as follows:

(1) Upfront License Fees: We determine whether upfront license fees are earned at the time of contract execution (i.e., when rights transfer to the customer) or over the actual (or implied) contractual period of the out-license. As part of this determination, we evaluate whether we have any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer. Our customers’ “distinct” rights to licensed “functional intellectual property” at the time of contract execution results in concurrent revenue recognition of all upfront license fees (assuming that there are no other performance obligations at contract execution that are inseparable from this license transfer).

(2) Royalties: Under the “sales-or-usage-based royalty exception” we recognize revenue in the same period that our

licensees complete product sales in their territory for which we are contractually entitled to a percentage-based royalty receipt.

(3) Sales Milestones: Under the “sales-or-usage-based royalty exception” we recognize revenue in full within the period that our licensees achieve annual or aggregate product sales levels in their territories for which we are contractually entitled to a specified lump-sum receipt.

(4) Regulatory Milestones: Under the terms of the respective out-license, regulatory achievements may either be our responsibility, or that of our licensee.

• When our licensee is responsible for the achievement of the regulatory milestone, we recognize revenue in full (for the contractual amount due from our licensee) in the period that the approval occurs (i.e., when the “performance obligation” is satisfied by our customer) under the “most likely amount” method. This revenue recognition remains “constrained” (i.e., not recognized) until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

• When we are responsible for the achievement of a regulatory milestone, the “relative selling price method” is applied for purposes of allocating the transaction price to our performance obligations. In such case, we consider (i) the extent of our effort to achieve the milestone and/or the enhancement of the value of the delivered item(s) as a result of milestone achievement and (ii) if the milestone payment is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. We have historically assessed the contractual value of these milestones upon their achievement to be identical to the allocation of value of our performance obligations and thus representing the “transaction price” for each milestone at contract inception. We recognize this revenue in the period that the regulatory approval occurs (i.e., when we complete the “performance obligation”) under the “most likely amount” method, and revenue recognition is otherwise “constrained” until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

(c) Service Revenue: We receive fees under certain arrangements for (i) sales and marketing services, (ii) supply chain services, (iii) research and development services, and (iv) clinical trial management services.

Our rights to receive payment for these services may be established by (1) a fixed-fee schedule that covers the term of the arrangement, so long as we meet ongoing performance obligations, (2) our completion of product delivery in our capacity as a procurement agent, (3) the successful completion of a phase of drug development, (4) favorable results from a clinical trial, and/or (5) regulatory approval events.

We consider whether revenue associated with these service arrangements is reportable each period, based on our completed services or deliverables (i.e., satisfied “performance obligations”) during the reporting period, and the terms of the arrangement that contractually result in fixed payments due to us. The promised service(s) within these arrangements are distinct and explicitly stated within each contract, and our customer benefits from the separable service(s) delivery/completion. Further, the nature of the promise to our customer as stated within the respective contract is to deliver each named service individually (not a transfer of combined items to which the promised goods or services are inputs), and thus are separable for revenue recognition.

(ii) Cash and Cash Equivalents

Cash and cash equivalents consist of bank deposits and highly liquid investments with maturities of three months or less from the purchase date.

(iii) Marketable Securities

Our marketable securities consist of our holdings in equity securities (beginning January 1, 2018 - see Note 3(a)), mutual funds, and bank certificates of deposit (“Bank CDs”). Beginning January 1, 2018, our realized and unrealized (losses) gains on marketable securities are included in “Other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations. Prior to January 1, 2018, our unrealized (losses) gains were included in “other comprehensive (loss) income” on our accompanying Condensed Consolidated Statements of Comprehensive Loss.

(iv) Accounts Receivable

Our accounts receivable are derived from our product sales and license fees (our service revenue is recorded in “other receivables”), and do not bear interest. The allowance for doubtful accounts is management’s best estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance after appropriate collection efforts are exhausted.

(v) Inventories

We value our inventory at the lower of (i) the actual cost of its purchase or manufacture, or (ii) its net realizable value. Inventory cost is determined on the first-in, first-out method. We regularly review our inventory quantities in process of manufacture and on hand. When appropriate, we record a provision for obsolete and excess inventory to derive its new cost basis, which takes into account our sales forecast by product and corresponding expiry dates of each product lot.

Manufacturing costs of drug products that are pending U.S. Food and Drug Administration (“FDA”) approval are expensed through “research and development,” on the accompanying Condensed Consolidated Statements of Operations (rather than being capitalized to “inventories”).

(vi) Property and Equipment

Our property and equipment is stated at historical cost, and is depreciated on a straight-line basis over an estimated useful life that corresponds with its designated asset category. We evaluate the recoverability of “long-lived assets” (which includes property and equipment) whenever events or changes in circumstances in our business indicate that the asset’s carrying amount may not be recoverable through our on-going operations.

(vii) Goodwill and Intangible Assets

Our goodwill represents the excess of our business acquisition cost over the estimated fair value of the net assets acquired in the corresponding transaction. Goodwill has an indefinite accounting life and is therefore not amortized. Instead, goodwill is evaluated for impairment on an annual basis (as of each October 1st), unless we identify impairment indicators that would require earlier testing.

We evaluate the recoverability of indefinite-lived intangible assets at least annually, or whenever events or changes in our business indicate that an intangible asset’s (whether indefinite or definite-lived) carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

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

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

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

Intangible assets with finite useful lives are amortized over their estimated useful lives on a straight-line basis. We review these assets for potential impairment if/when facts or circumstances suggest that the carrying value of these assets may not be recoverable.

(viii) Stock-Based Compensation

Stock-based compensation expense for equity awards granted to our employees and members of our Board of Directors is recognized on a straight-line basis over each award’s vesting period. Recognized compensation expense is net of an estimated forfeiture rate, representing the percentage of awards that are expected to be forfeited prior to vesting, though is ultimately adjusted for actual forfeitures. We use the Black-Scholes option pricing model to determine the fair value of stock options (as of the date of grant) that have service conditions for vesting. We use the Monte Carlo valuation model to value equity awards (as of the date of grant) that have combined market conditions and service conditions for vesting.

The recognition of stock-based compensation expense and the initial calculation of stock option fair value requires uncertain assumptions, including (a) the pre-vesting forfeiture rate of the award, (b) the expected term that the stock option will remain outstanding, (c) our stock price volatility over the expected term (and that of our designated peer group with respect to certain market-based awards), and (d) the prevailing risk-free interest rate for the period matching the expected term.

With regard to (a)-(d): We estimate forfeiture rates based on our employees’ overall forfeiture history, which we believe will be representative of future results. We estimate the expected term of stock options granted based on our employees’ historical exercise patterns, which we believe will be representative of their future behavior. We estimate the volatility of our common stock on the date of grant based on the historical volatility of our common stock for a look-back period that corresponds with the expected term. We estimate the risk-free interest rate based upon the U.S. Department of the Treasury yields in effect at award grant, for a period equaling the expected term of the stock option.

(ix) Foreign Currency Translation

Our foreign subsidiaries’ separate financial statements are stated in their functional currencies (i.e., local operating currencies). To create the accompanying Condensed Consolidated Financial Statements, we translate the assets and liabilities of our subsidiaries to U.S. dollars at the rates of exchange in effect at the reported balance sheet date; revenues and expenses are translated using the monthly average exchange rates during the reported period. Unrealized gains and losses from these translations are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

We record foreign currency-based transactions (i.e., when not denominated in the functional currency of our transacting legal entity) at the prevailing exchange rate on the date of the transaction. Resulting unrealized foreign exchange gains and losses from these unsettled transactions are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

All unrealized foreign exchange gains and losses associated with our intercompany loans are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets, as these loans with our foreign subsidiaries are not expected to be settled in the “foreseeable future.”

(x) Basic and Diluted Net Loss per Share

We calculate basic and diluted net loss per share using the weighted average number of common shares outstanding during the periods presented. In periods of a net loss, 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 only dilutive stock options, warrants, and other common stock equivalents outstanding during the period.

(xi) Income Taxes

Deferred tax assets and liabilities are recorded based on the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain.

We have recorded a valuation allowance to reduce our deferred tax assets, because we believe that, based upon a weighting of positive and negative factors, it is more likely than not that these deferred tax assets will not be realized. If/when we were to determine that our deferred tax assets are realizable, an adjustment to the corresponding valuation allowance would increase our net income in the period that such determination was made.

In the event that we are assessed interest and/or penalties from taxing authorities that have not been previously accrued, such amounts would be included in “(provision) benefit for income taxes” within the Condensed Consolidated Statements of Operations for the period in which we received the notice.

(xii) Research and Development Costs

Our research and development costs are expensed as incurred (see Note 15(c)), or as certain milestone payments become contractually due to our licensors, as triggered by the achievement of clinical or regulatory events.

(xiii) Fair Value Measurements

We determine measurement-date fair value based on the proceeds that would be received through the sale of the asset, or that we would pay to settle or transfer the liability, in an orderly transaction between market participants. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. 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 publicly accessible at the measurement date.

Level 2: Observable prices that are based on inputs not quoted on active markets, but that are corroborated by market data. These inputs may include quoted prices for similar assets or liabilities or quoted market prices in markets that are not active to the general public.

Level 3: Unobservable inputs are used when little or no market data is available.

Balance Sheet Account Detail

BALANCE SHEET ACCOUNT DETAIL

The composition of selected financial statement captions that comprise the accompanying Condensed Consolidated Balance Sheets are summarized below:

(a) Cash and Cash Equivalents and Marketable Securities

As of September 30, 2018 and December 31, 2017, our “cash and cash equivalents” were held with major financial institutions. Our “marketable securities” primarily relate to our equity holdings in CASI (as defined below).

We maintain cash balances in excess of federally insured limits with reputable financial institutions. To a limited degree, the Federal Deposit Insurance Corporation and other 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 in our portfolio by investing in highly liquid, highly-rated instruments, and limit investing in long-term maturity instruments.

Our investment policy requires that purchased investments in marketable securities may only be in highly-rated instruments, which are primarily U.S. treasury bills or treasury-backed securities, and also limits our investments in securities of any single issuer (excluding any debt or equity securities received from our strategic partners in connection with an out-license arrangement, as discussed in Note 10).

The carrying amount of our equity securities, money market funds, and Bank CDs approximates their fair value (utilizing “Level 1” or “Level 2” inputs – see Note 2(xiii)) because of our ability to immediately convert these instruments into cash with minimal expected change in value.

The following is a summary of our presented “cash and cash equivalents” and “marketable securities”:

	Cost		Foreign Currency Translation			Gross Unrealized Gains*		Gross Unrealized Losses		Estimated Fair Value		Cash and Cash Equivalents		Marketable Securities
September 30, 2018
Equity securities* (see Note 3(g) and Note 10)	$	8,710	$	(1,920	)	$	47,138	$	—	$	53,928	$	—	$	53,928

Total cash and cash equivalents and marketable securities	$	227,571	$	—		$	—	$	—	$	227,571	$	227,323	$	248

* Beginning January 1, 2018, under the new requirements of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities, the unrealized (losses) gains on our CASI Pharmaceuticals, Inc. (NASDAQ: CASI) (“CASI”) equity securities are recognized as a (decrease) increase to “other (expense) income, net” on the Consolidated Statements of Operations (rather than through “other comprehensive (loss) income” on the Consolidated Statements of Comprehensive Loss). Our adoption of ASU 2016-01 on January 1, 2018, resulted in a $17.2 million cumulative-effect adjustment, net of income tax, recorded as a decrease to “accumulated other comprehensive (loss) income” and a decrease to “accumulated deficit” on the accompanying Condensed Consolidated Balance Sheets. Our recognized unrealized loss on these equity securities for the three months ended September 30, 2018 was $40.9 million and our recognized unrealized gain on these equity securities for the nine months ended September 30, 2018 was $17.7 million, as reported in “other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations.

As of September 30, 2018, none of our securities were in an unrealized loss position.

(b) Property and Equipment, net of Accumulated Depreciation

“Property and equipment, net of accumulated depreciation” consists of the following:

	September 30, 2018			December 31, 2017
Computer hardware and software	$	3,076		$	2,994
Laboratory equipment	635			630
Office furniture	212			218
Leasehold improvements	2,938			2,938
Property and equipment, at cost	6,861			6,780
(Less): Accumulated depreciation	(6,424		)	(6,191		)
Property and equipment, net of accumulated depreciation	$	437		$	589

Depreciation expense (included within “total operating costs and expenses” in the accompanying Condensed Consolidated Statements of Operations) for the three and nine months ended September 30, 2018 and 2017, was $0.1 million, $0.1 million, $0.2 million, and $0.2 million, respectively.

New Accounting Standard for Leases, effective January 1, 2019

In February 2016, the FASB issued ASU 2016-02, which amends the FASB Accounting Standards Codification and creates Topic 842, Leases (“Topic 842”). The new topic supersedes Topic 840, Leases and requires additional disclosures regarding our lease arrangements, as well as our presentation of lease assets and lease liabilities (including those for operating leases) on the balance sheet at the present value of lease payments not yet paid, and for us to subsequently apply the “effective interest rate” method” to reduce the lease liability, while amortizing the right-of-use asset for straight-line expense recognition over the lease term.

Topic 842 is effective for us beginning January 1, 2019, and mandates a “modified retrospective” transition method. We are currently assessing the quantitative impact this guidance will have on our consolidated financial statements. However, we presently do not have any capital lease arrangements, or any active contracts that would contain an “embedded lease”. Our current operating lease arrangements affected by this “gross-up” presentation are limited to (1) our executive, administrative, and research and development office facilities and (2) certain office equipment.

(c) Inventories

“Inventories” consists of the following:

	September 30, 2018			December 31, 2017
Raw materials	$	1,870		$	1,077
Work-in-process	2,569			2,551
Finished goods	1,515			5,187
(Less:) Non-current portion of inventories included within "other assets" *	(1,975		)	(3,100		)
Inventories	$	3,979		$	5,715

* The “non-current” portion of inventories is presented within “other assets” in the accompanying Condensed Consolidated Balance Sheets at September 30, 2018 and December 31, 2017, respectively. This value of $2 million at September 30, 2018 represents product that we expect to sell beyond September 30,2019, and the value at December 31, 2017 represented product that we expected to sell beyond December 31, 2018.

(d) Prepaid Expenses and Other Assets

“Prepaid expenses and other assets” consists of the following:

	September 30, 2018		December 31, 2017
Other miscellaneous prepaid operating expenses	$	7,186	$	3,389
Prepaid insurance	131		645
Research and development supplies	983		1,883
Key employee life insurance - cash surrender value	—		4,150
Prepaid expenses and other assets	$	8,300	$	10,067

(e) Other Receivables

“Other receivables” consists of the following:

	September 30, 2018		December 31, 2017
Other miscellaneous receivables (including Medicaid rebate credits and royalty receivables)	$	1,147	$	1,152
Income tax receivable	632		665
Insurance receivable	1,458		53
CASI note - short term	1,523		—
Reimbursements due from development partners for incurred research and development expenses	371		263
Other receivables	$	5,131	$	2,133

(f) Intangible Assets and Goodwill

Intangible assets, net of accumulated amortization and impairment charges consists of the following:

			September 30, 2018
	Historical Cost		Accumulated Amortization			Foreign Currency Translation			Impairment			Net Amount		Full Amortization Period (months)	Remaining Amortization Period (months)
MARQIBO IPR&D (NHL and other novel indications)	$	17,600	$	—		$	—		$	—		$	17,600	n/a	n/a
EVOMELA distribution rights	7,700		(1,481		)	—			—			6,219		156	126
BELEODAQ distribution rights	25,000		(7,969		)	—			—			17,031		160	109
MARQIBO distribution rights	26,900		(20,420		)	—			—			6,480		81	21
FOLOTYN distribution rights (1)	118,400		(63,918		)	—			—			54,482		152	50
ZEVALIN distribution rights – U.S.	41,900		(40,163		)	—			—			1,737		123	6
ZEVALIN distribution rights – ex-U.S.	23,490		(17,913		)	(3,132		)	—			2,445		96	18
FUSILEV distribution rights (2)	16,778		(9,618		)	—			(7,160		)	—		56	0
FOLOTYN out-license (3)	27,900		(16,598		)	—			(1,023		)	10,279		110	46
Total intangible assets	$	305,668	$	(178,080	)	$	(3,132	)	$	(8,183	)	$	116,273

(1) Beginning June 2016, we adjusted the amortization period of our FOLOTYN distribution rights to November 2022 from March 2025, representing the period through which we expect to have patent protection from generic competition.

(2) On February 20, 2015, the United States District Court for the District of Nevada found the patent covering FUSILEV to be invalid, which was upheld on appeal. On April 24, 2015, Sandoz began to commercialize a generic version of FUSILEV. This represented a “triggering event” under applicable GAAP in evaluating the value of our FUSILEV distribution rights as of March 31, 2015, resulting in a recognized $7.2 million impairment charge (non-cash) in 2015. We accelerated amortization expense recognition in 2015 for the then remaining net book value of FUSILEV distribution rights.

(3) On May 29, 2013, we amended our FOLOTYN collaboration agreement with Mundipharma. As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and their royalty rates and milestone payments to us were modified. This constituted a change under which we originally valued the FOLOTYN out-license as part of business combination accounting, resulting in a recognized impairment charge (non-cash) of $1 million in 2013.

			December 31, 2017
	Historical Cost		Accumulated Amortization			Foreign Currency Translation			Impairment			Net Amount
MARQIBO IPR&D (NHL and other novel indications)	$	17,600	$	—		$	—		$	—		$	17,600
EVOMELA distribution rights	7,700		(1,037		)	—			—			6,663
BELEODAQ distribution rights	25,000		(6,563		)	—			—			18,437
MARQIBO distribution rights	26,900		(17,182		)	—			—			9,718
FOLOTYN distribution rights	118,400		(54,111		)	—			—			64,289
ZEVALIN distribution rights – U.S.	41,900		(37,557		)	—			—			4,343
ZEVALIN distribution rights – ex-U.S.	23,490		(17,232		)	(2,471		)	—			3,787
FUSILEV distribution rights	16,778		(9,618		)	—			(7,160		)	—
FOLOTYN out-license	27,900		(14,555		)	—			(1,023		)	12,322
Total intangible assets	$	305,668	$	(157,855	)	$	(2,471	)	$	(8,183	)	$	137,159

Intangible asset amortization expense recognized during the three and nine months ended September 30, 2018 and 2017, was $6.9 million, $6.9 million, $20.8 million and $20.7 million, respectively.

Estimated intangible asset amortization expense for the remainder of 2018 and the five succeeding fiscal years and thereafter is as follows:

Years Ending December 31,

2022	15,882
2023	2,467
2024 and thereafter	10,297
	$	98,673

“Goodwill” consists of the following, by source:

	September 30, 2018			December 31, 2017

Business Combinations [Abstract]

Business Combinations and Contingent Consideration

BUSINESS COMBINATIONS AND CONTINGENT CONSIDERATION

(a) Acquisition of Talon Therapeutics, Inc.

Overview of Talon Acquisition

On July 17, 2013, we purchased all of the outstanding shares of common stock of Talon Therapeutics, Inc. (“Talon”). Through the acquisition of Talon, we gained worldwide rights to MARQIBO. The Talon purchase consideration consisted of (i) an aggregate upfront cash amount of $11.3 million, (ii) issuance of 3 million shares of our common stock, then equivalent to $26.3 million (based on a closing price of $8.77 per share on July 17, 2013), and (iii) the issuance of a contingent value right (“CVR”) initially valued at $6.5 million.

The CVR was valued using a valuation model that probability-weights expected outcomes (ranging from 50% to 100%) and discounts those amounts to their present value, using an appropriate discount rate (these represent unobservable inputs and are therefore classified as Level 3 inputs – see Note 2 (xiii)). The CVR has a maximum payout of $195 million if all sales and regulatory approval milestones are achieved, as summarized below:

• $5 million upon the achievement of net sales of MARQIBO in excess of $30 million in any calendar year

• $10 million upon the achievement of net sales of MARQIBO in excess of $60 million in any calendar year

• $25 million upon the achievement of net sales of MARQIBO in excess of $100 million in any calendar year

• $50 million upon the achievement of net sales of MARQIBO in excess of $200 million in any calendar year

• $100 million upon the achievement of net sales of MARQIBO in excess of $400 million in any calendar year

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

Talon CVR Fair Value as of September 30, 2018 and December 31, 2017

The CVR fair value will continue to be evaluated on a quarterly basis. Current and future changes in its fair value results from the likelihood and timing of milestone achievement and/or the corresponding discount rate applied thereon. Adjustments to CVR fair value are recognized within “change in fair value of contingent consideration related to acquisitions” in the accompanying Condensed Consolidated Statements of Operations.

	Fair Value of Talon CVR
December 31, 2017	$	6,210
Fair value adjustment for the nine months ended September 30, 2018	(655		)
September 30, 2018	$	5,555

(b) Acquisition of Rights to EVOMELA and Related Contingent Consideration

Overview of Acquisition of Rights to EVOMELA

In March 2013, we completed the acquisition of exclusive global development and commercialization rights to Captisol-enabled®, propylene glycol-free MELPHALAN (which we branded as “EVOMELA”) for use as a conditioning treatment prior to autologous stem cell transplant for patients with MM. We acquired these rights from CyDex pharmaceuticals, Inc. (“Cydex”) a wholly-owned subsidiary of Ligand Pharmaceuticals Inc. (“Ligand”) for an initial license fee of $3 million, and assumed responsibility for EVOMELA’s then-ongoing clinical and regulatory development program. We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the transaction date.

We are required to pay Ligand additional amounts up to an aggregate of $60 million upon the achievement of annual net sales thresholds (exclusive of the $6 million milestone payment triggered in March 2016, as discussed below), however, we do not expect to achieve these sales thresholds based on our estimated market size for this product and our projected market share at the time of the acquisition and to date. We also must pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.

Our EVOMELA royalty obligation and sales-based milestones are jointly treated as part of an “executory contract” (as defined under GAAP) that is connected with an at-market supply agreement for Captisol that was executed concurrently with this acquisition (requiring the continuing involvement of CyDex). As a result, our royalty obligation and sales-based milestone arrangements are treated as separate transactions, distinct from the consideration for the EVOMELA rights. Our royalty expenses are reported through “cost of sales” in our Condensed Consolidated Statements of Operations in the same period of our recognized revenue for the product sale.

Consideration Transferred

The acquisition-date fair value of the consideration transferred consisted of the following:

Cash consideration	$	3,000
Ligand 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 transaction date. The allocation of the total purchase price to the net assets acquired is as follows:

EVOMELA IPR&D rights $ 7,700

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 net cash flows to a single present value (discounted) amount.  We applied our net cash flow projections for EVOMELA over 10 years and a discount rate of 25%, taking into account our estimates of future incremental earnings that may be achieved upon regulatory approval and commercialization of the product(s). The fair value of the Ligand Contingent Consideration (as defined below) liability was determined using the probability of success and the discounted cash flow method of the income approach (representing unobservable “Level 3” inputs (see Note 2(xiii))for regulatory and sales-based milestones due to Ligand upon achievement).

In March 2016, the FDA approved EVOMELA, triggering a $6 million milestone payment to Ligand (“Ligand Contingent Consideration”) that was paid in April 2016. “EVOMELA IPR&D” of $7.7 million was reclassified in April 2016 to “EVOMELA distribution rights” that is reported within “Intangible assets, net of accumulated amortization” in the accompanying Condensed Consolidated Balance Sheets as of September 30, 2018 (see Note 3(f)). Amortization related to this intangible asset commenced on April 1, 2016.

(c) Allos Acquisition

We acquired Allos Therapeutics, Inc. (“Allos”) in September 2012 for cash consideration of $205.2 million and assumed its FOLOTYN distribution rights (see Note 14). We accounted for this transaction as a business combination, which required that assets acquired and liabilities assumed be reported on our balance sheet at their fair values as of the transaction date. We have no ongoing contingent consideration obligations from this transaction.

Out-License of Marqibo, Zevalin, & Evolema in China Territory

OUT-LICENSE OF MARQIBO, ZEVALIN, & EVOMELA IN CHINA TERRITORY

Overview of CASI Out-License

In September 2014, we executed three perpetual out-license agreements for ZEVALIN, MARQIBO, and EVOMELA (“CASI Out-Licensed Products”) with CASI, a publicly-traded biopharmaceutical company (NASDAQ: CASI) with a primary focus on the China market (collectively, the “CASI Out-License”). Under the CASI Out-License, we received CASI common stock and a secured promissory note; CASI gained the exclusive rights to distribute these drug products in greater China (which includes Taiwan, Hong Kong and Macau).

CASI is responsible for the development and commercialization of these drugs, including the submission of import drug registration applications to regulatory authorities and conducting any confirmatory clinical studies in greater China. We will provide CASI with future commercial supply of the CASI Out-Licensed Products under typical market terms.

Our Ownership in CASI at September 30, 2018

Under certain conditions that expired in December 2017, we had a right to purchase additional shares of CASI common stock in order to maintain our post-investment ownership percentage. During 2017 and 2016, we acquired an additional 1.5 million and 4.6 million CASI common shares at par value, respectively. Our aggregate holding of 11.5 million common shares as of September 30, 2018 represented an approximate 12.36% ownership in CASI, with a fair market value of $53.9 million (see Note 3(a)).

Proceeds Received from CASI in 2014

The proceeds we received in 2014, and its fair value on the CASI Out-License execution date, consisted of the following:

CASI common stock (5.4 million shares)	$	8,649	(a)
CASI secured promissory note, net of fair value discount ($1.5 million face value and 0.5% annual coupon)	1,310		(b)
Total consideration received, net of fair value discount	$	9,959	(c)

(a) Value determined based on the September 17, 2014 closing price of 5.4 million shares of CASI common stock on the NASDAQ Capital Market of $1.60 per share.

(b) Value estimated using the terms of the $1.5 million promissory note, the application of a synthetic debt rating based on CASI’s publicly-available financial information, and the prevailing interest yields on similar public debt securities as of September 17, 2014. This full balance was reclassified beginning December 31, 2017 to “other assets” (presented within non-current assets on the accompanying Condensed Consolidated Balance Sheets) from “other receivables” (presented within current assets) due to an amended maturity date of September 17, 2019.

(c) Presented within “license fees and service revenue” in the Consolidated Statements of Operations for the year ended December 31, 2015 (see below).

In addition, CASI will be responsible for paying any royalties or milestones that we are obligated to pay to our third-party licensors resulting from the achievement of certain milestones and/or sales of CASI Out-Licensed Products, but only to the extent of the greater China portion of such royalties or milestones.

License Fee Revenue Recognized in 2015

The $9.7 million value of the upfront proceeds (undiscounted, and net of certain foreign exchange adjustments) from CASI were recognized in 2015 within “license fees and service revenue” on our Consolidated Statements of Operations. The delayed timing of this revenue recognition corresponded with the execution of certain supply agreements with CASI for ZEVALIN, MARQIBO, and EVOMELA. These agreements allow CASI to procure CASI Out-Licensed Products directly from approved third parties, and in such case, do not require our future involvement for its commercial supply.

Co-Promotion Arrangement With Eagle Pharmaceuticals

CO-PROMOTION ARRANGEMENT WITH EAGLE PHARMACEUTICALS

In November 2015, we executed an agreement with Eagle Pharmaceuticals, Inc. (“Eagle”) whereby designated members of our sales force concurrently marketed up to six of Eagle’s products (along with our products). This arrangement was in return for fixed monthly payments (aggregating $12.8 million) and variable sales-based milestones from Eagle over an 18 month contract term from January 1, 2016 through June 30, 2017 (the “Eagle Agreement”). On July 1, 2017, our sales force ceased marketing Eagle products and the Eagle Agreement expired under its terms.

The fixed receipts from Eagle for our sales activities, as well as reimbursements of third-party marketing services, are recognized within “license fees and service revenue” on our accompanying Condensed Consolidated Statements of Operations, and was $4.7 million for the nine months ended September 30, 2017. No sales-based milestones were achieved.

An allocation of costs for our sales personnel that were dedicated to the Eagle Agreement are reported within “cost of service revenue” on our accompanying Condensed Consolidated Statements of Operations, as are reimbursed costs for Eagle marketing activities; these were an aggregate $4.2 million for the nine months ended September 30, 2017.

Convertible Senior Notes

CONVERTIBLE SENIOR NOTES

Overview of Convertible Notes and Conversion Hedge

On December 17, 2013, we entered into an agreement for the sale of $120 million aggregate principal amount of 2.75% Convertible Senior Notes (equaling 120,000 notes, denominated in $1,000 principal units) due December 2018 (the “2018 Convertible Notes”). As of September 30, 2018 and December 31, 2017, $35.8 million and $40.6 million of principal of the 2018 Convertible Notes was outstanding, respectively, due to our open market purchases discussed below, as well as $4.7 million of principal value, converted by a holder in July 2018 into 451,300 common shares.

The 2018 Convertible Notes are convertible into shares of our common stock at a conversion rate of 95 shares per $1,000 principal units, equating to 3.4 million common shares if fully converted at September 30, 2018. The in-the-money conversion price is equivalent to $10.53 per common share. The conversion rate and conversion price is subject to adjustment under certain limited circumstances. The 2018 Convertible Notes bear interest at a rate of 2.75% per year, payable semiannually in arrears on June 15 and December 15 of each year. The 2018 Convertible Notes will mature and become payable on December 15, 2018, subject to earlier conversion into common stock at the holders’ option.

The sale of the 2018 Convertible Notes closed on December 23, 2013 and we received net proceeds of $115.4 million, after deducting banker and professional fees of $4.6 million. We used a portion of these net proceeds to simultaneously enter into “bought call” and “sold warrant” transactions with Royal Bank of Canada (collectively, the “Conversion Hedge”). We recorded the Conversion Hedge on a net cost basis of $13.1 million, as a reduction to “additional paid-in capital” in our accompanying Condensed Consolidated Balance Sheets. Under applicable GAAP, the Conversion Hedge transaction has not been (and is not expected to be) marked-to-market through earnings or comprehensive income.

On and after June 15, 2018, and until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all, or a portion, of their 2018 Convertible Notes. Our stockholders’ approved “flexible settlement” our Annual Meeting of Stockholders on June 29, 2015, though on September 27, 2018, we elected to exclusively settle any and all conversions with our common stock. However, if the holders of our 2018 Convertible Notes do not elect to convert, our December 2018 obligation to repay the remaining principal amount of $35.8 million in cash, plus any accrued and unpaid interest, will remain unchanged.

We entered into Conversion Hedge transactions in December 2013 to reduce the potential dilution to our stockholders and/or offset any cash payments that we are required to make in excess of the principal amount, upon conversion of the 2018 Convertible Notes (in the event that the market price of our common stock is greater than the conversion price). The strike price of the “bought call” is equal to the conversion price and conversion rate of the 2018 Convertible Notes (at such time, it matched the 11.4 million common shares into which the holders could convert the 2018 Convertible Notes); the strike price of our “sold warrant” is $14.03 per share of our common stock, and is also for 11.4 million common shares (reduced by the partial unwinding of these instruments, as discussed above).

Open Market Purchases of 2018 Convertible Notes and Conversion Hedge Unwind in December 2016 and October 2017

In December 2016, we completed two open market purchases of our 2018 Convertible Notes, aggregating 9,963 note units (equivalent to $10 million principal value) for $9 million in cash. We recognized an aggregate loss of $25 thousand on the retirement of these 2018 Convertible Notes (based on their carrying value under GAAP), which is included in “other income (expense), net” on the Consolidated Statements of Operations for the year ended December 31, 2016. Concurrent with these two open market purchases in December 2016, we unwound a portion of our previously sold warrants and previously purchased call options (which were part of our Conversion Hedge described below) for aggregate net proceeds of $21 thousand. We recorded a corresponding net increase to “additional paid-in capital” in the Consolidated Balance Sheets as of December 31, 2016.

In October 2017, we completed an additional open market purchase of our 2018 Convertible Notes, aggregating 69,472 note units (equivalent to $69.5 million principal value) for $27.3 million in cash and 5.4 million newly-issued shares of our common stock, then worth $73 million. We recognized a loss of $0.8 million on the retirement of these 2018 Convertible Notes (based on their carrying value under GAAP), which was included in “other (expense) income, net” on the Consolidated Statements of Operations for the year ended December 31, 2017.

Concurrent with this open market purchase in October 2017, we also unwound a portion of the previously sold warrants and previously purchased call options that were part of our Conversion Hedge for aggregate net proceeds of $5.8 million. We recorded a corresponding net increase to “additional paid-in capital” in the Consolidated Balance Sheets as of December 31, 2017.

Carrying Value and Fair Value of 2018 Convertible Notes at September 30, 2018 and December 31, 2017

The carrying value of the 2018 Convertible Notes as of September 30, 2018 and December 31, 2017, is summarized as follows:

	September 30, 2018			December 31, 2017
Principal amount	$	35,815		$	40,565

FOLOTYN License Agreement And Development Liability

FOLOTYN LICENSE AGREEMENT AND DEVELOPMENT LIABILITY

As the result of our acquisition of Allos on September 5, 2012 (see Note 9(c)), we assumed a strategic collaboration agreement with Mundipharma (as amended and/or restated, the “Mundipharma Collaboration Agreement”), as well as certain FOLOTYN clinical development obligations (the “FOLOTYN Development Liability”).

Overview of Mundipharma Collaboration Agreement

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. On May 29, 2013, the Mundipharma Collaboration Agreement was amended and restated, in order to modify: (i) the scope of the licensed territory, (ii) milestone payments, (iii) royalty rates, and (iv) drug development obligations. In connection with the amendment and restatement of the Mundipharma Collaboration Agreement, we received a one-time $7 million payment from Mundipharma for certain research and development activities to be performed by us.

As a result of the amendment and restatement of the Mundipharma Collaboration Agreement, (a) Europe and Turkey were excluded from Mundipharma’s commercialization territory, (b) we may receive regulatory milestone payments of up to $16 million, and commercial progress and sales-dependent milestone payments of up to $107 million (see Note 15(b)(vii) for July 2017 achievement), (c) we will receive tiered double-digit royalties based on net sales of FOLOTYN within Mundipharma’s licensed territories, and (d) we and Mundipharma will each bear our own FOLOTYN development costs. Effective as of May 1, 2015, we modified the Mundipharma Collaboration Agreement to revise the conditions for our exercise of the option to gain commercialization rights in Switzerland from Mundipharma, as well as royalties payable to us (in the tiered double-digits) on Mundipharma’s net sales in Switzerland.

FOLOTYN Development Liability

The fair value of the FOLOTYN Development Liability within the accompanying Consolidated Balance Sheets was estimated using the discounted income approach model. The unobservable inputs (i.e., “Level 3” inputs - see Note 2(xiii)) in this valuation model that have the most significant effect on these liabilities include (i) estimates of research and development personnel costs needed to perform the research and development services contractually required, (ii) estimates of expected cash outflows to third parties for these clinical services and supplies during the expected period of performance through 2031, and (iii) an appropriate discount rate for these expenditures. These inputs are reviewed by management on a quarterly basis for continued applicability.

We adjust this liability at each quarter-end, with corresponding adjustments for incurred costs recorded as credits to “research and development” expense in our accompanying Condensed Consolidated Statements of Operations. 

	FOLOTYN Development Liability, Current			FOLOTYN Development Liability, Long Term			FOLOTYN Development Liability, Total
Balance as of December 31, 2017	$	275		$	12,111		$	12,386
Transfer from long-term to current in 2018	206			(206		)	—
(Less): Expenses incurred in 2018	(270		)	—			(270		)
Balance as of September 30, 2018	$	211		$	11,905		$	12,116

Commitments and Contingencies Disclosure [Abstract]

Financial Commitments & Contingencies And License Agreements

FINANCIAL COMMITMENTS & CONTINGENCIES AND LICENSE AGREEMENTS

(a) Facility Leases

We lease our principal executive office in Henderson, Nevada under a non-cancelable operating lease expiring April 30, 2019. We also lease our research and development facility in Irvine, California under a non-cancelable operating lease expiring May 31, 2019, in addition to several other administrative office leases. Each lease agreement contains scheduled rent increases which are accounted for on a straight-line basis.

(b) In/Out Licensing Agreements and Co-Development Arrangements

The in-license agreements for our commercialized and development-stage drug products provide us with territory-specific rights to their manufacture and distribution (including further sub-licensing/out-licensing, rights). We are generally responsible for all related clinical development costs, patent filings and maintenance costs, marketing costs, and liability insurance costs. We are also obligated to make specified milestone payments to our licensors upon the achievement of certain regulatory and sales milestones, and to pay royalties based on our net sales of all in-licensed products. We also enter into out-license agreements for territory-specific rights to our drug products which include one or more of: upfront license fees, royalties from our licensees’ sales, and/or milestone payments from our licensees’ sales or regulatory achievements. For certain development-stage drug products, we may enter into cost-sharing arrangements with our licensees and licensors.

Our most significant of these agreements, and the key financial terms and our accounting for each, are summarized below:

(i) ZEVALIN U.S.: In-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. through our wholly-owned subsidiary, RIT Oncology LLC. In accordance with the terms of assumed contracts, we were required to meet specified payment obligations, including a milestone payment to Corixa Corporation of $5 million based on ZEVALIN sales in the United States. As of September 30, 2018 all the patents licensed from Corixa had expired under the terms of the agreement. Under the terms of the agreement, we are no longer obligated to pay U.S. net sales-based royalties in the low to mid-single digits to Genentech, Inc. and mid-teens to Biogen, Inc.

(ii) ZEVALIN Ex-U.S.: In-License and Asset Purchase Agreement with Bayer Pharma

In April 2012, through our wholly-owned subsidiary, Spectrum Pharmaceuticals Cayman, L.P., we completed a €19 million acquisition of licensing rights to market ZEVALIN outside of the U.S. from Bayer. ZEVALIN is currently approved in approximately 40 countries outside the U.S. for the treatment of B-cell NHL, including countries in Europe, Latin America, and Asia.

We amended the agreement in February 2016, which adjusted our tiered royalty to Bayer from the single-digits to 20%. The term of the agreement, as amended, continues until the expiration of the last-to-expire ZEVALIN patent in the relevant country, or 15 years from the date of first commercial sale of ZEVALIN in such country, whichever is longer.

(iii) ZEVALIN Ex-U.S.: Out-License Agreement with Dr. Reddy’s

In June 2014, we executed an exclusive License Agreement with Dr. Reddy’s Laboratories Ltd. (“Dr. Reddy’s”) for ZEVALIN distribution rights within India. The agreement term is 15 years from the receipt of pending approval of ZEVALIN from the Drug Controller General of India. In December 2014, upon our execution of a drug supply agreement, an upfront and non-refundable payment of $0.5 million was triggered and paid to us in February 2015. The recognition of the applicable portion of this upfront receipt is no longer reported on a straight-line basis within “license fees and service revenue” on our accompanying Condensed Consolidated Statements of Operations, due to the adoption of Topic 606 as of January 1, 2018 (see Note 2(i)). Additionally, sales and regulatory milestones, each aggregating $1.5 million (for a total of $3 million if both are achieved) are due to us upon Dr. Reddy’s achievement of such milestones, as well as a 20% royalty on its net sales of ZEVALIN in India.

(iv) ZEVALIN Ex-U.S.: Out-License Agreement with Mundipharma

In November 2015, we entered into an out-license agreement with Mundipharma for its commercialization of ZEVALIN in Asia (excluding India and Greater China), Australia, New Zealand, Africa, the Middle East, and Latin America (including the Caribbean islands). In return, we received $18 million (comprised of $15 million received in December 2015 and $3 million received in January 2016). Of these proceeds, $15 million was recognized within “license fees and service revenue” in the fourth quarter of 2015, and the remaining $3 million payment was recognized in full by June 30, 2017. Mundipharma is required to reimburse us for our payment of royalties due to Bayer from its ZEVALIN sales (see Note 15(b)(ii)).

In March 2018, Mundipharma achieved a specified sales milestone, resulting in a $2 million receipt due to us (subsequently received in April 2018); this amount was recognized within “license fees and service revenue” on our accompanying Condensed Statements of Operations for the nine months ended September 30, 2018 (see Note 5).

(v) FUSILEV: In-License Agreement with Merck & Cie AG

In May 2006, we amended and restated a license agreement with Merck & Cie AG (“Merck”), which we assumed in connection with our March 2006 acquisition of the assets of Targent, Inc. This provided us with an exclusive license to use regulatory filings related to FUSILEV, and a non-exclusive license under certain patents and know-how to develop, manufacture, and sell FUSILEV in the field of oncology in North America.

The contractual royalty percentage on our FUSILEV net sales due to Merck is set at the mid-single digits; however, in September 2017, we paid Merck $2.6 million in full settlement of all royalty obligations under the agreement. As a result, we are no longer contractually obligated to pay any royalties or milestones for our net sales of FUSILEV.

(vi) FOLOTYN: In-License Agreement with Sloan-Kettering Institute, SRI International and Southern Research Institute

In December 2002, Allos entered into an in-license agreement for the drug now marketed as FOLOTYN with Sloan-Kettering Institute for Cancer Research, SRI International (SRI), and Southern Research Institute. We assumed this agreement when we acquired Allos in September 2012. The agreement provides for our exclusive worldwide rights to a portfolio of patents and patent applications related to FOLOTYN, though we are required to fund certain drug development programs. In addition, we pay graduated royalties to our licensors based on our worldwide annual net sales of FOLOTYN (including our sub- licensees). These royalties are 8% of annual worldwide net sales up to $150 million; 9% of annual worldwide net sales of $150 million through $300 million; and 11% of annual worldwide net sales in excess of $300 million. We are also obligated to remit a $3.5 million payment to SRI upon approval of FOLOTYN by the European Medicines Agency (“EMA”) approval of FOLOTYN. This regulatory milestone has not been met, and no amounts have been accrued in our accompanying Condensed Balance Sheets for its potential achievement.

(vii) FOLOTYN: Out-License Agreement with Mundipharma

As a result of our acquisition of Allos (see Note 10(c)), we assumed “the Mundipharma Collaboration Agreement” as well as certain FOLOTYN clinical development obligations. Under the Mundipharma Collaboration Agreement (see Note 14), we retained full commercialization rights for FOLOTYN in the U.S. and Canada, with Mundipharma having exclusive rights to commercialize FOLOTYN in all other countries in the world, except in Europe and Turkey. We are contractually entitled to receive regulatory and sales milestone payments from Mundipharma upon its achievement of such milestones, which aggregate $16 million and $107 million, respectively, as well as tiered double-digit royalties on Mundipharma’s net sales.

In July 2017, FOLOTYN was approved in Japan for the treatment of adult patients with relapsed or refractory peripheral T-cell lymphoma. Consequently, we received $3 million from Mundipharma in August 2017 for this milestone achievement. This amount was recognized within “license fees and service revenue” on our Consolidated Statements of Operations for the year ended December 31, 2017.

In August 2017, FOLOTYN was commercially launched in Japan. This triggered a contractual milestone of $2 million from Mundipharma. This amount was recorded within “license fees and service revenue” on our Consolidated Statements of Operations for the year ended December 31, 2017.

(viii) EVOMELA: In-License Agreement with CyDex Pharmaceuticals, Inc.

In March 2013, we completed the acquisition of exclusive global development rights to EVOMELA from CyDex, a wholly-owned subsidiary of Ligand (see Note 9(b)), and assumed responsibility for its then-ongoing clinical and regulatory development program. We filed a New Drug Application (“NDA”) with the FDA in December 2015 for its use as a conditioning treatment prior to autologous stem cell transplant for patients with MM, and in March 2016, the FDA communicated its approval. Consequently, we made a $6 million contractual milestone payment to Ligand in April 2016. We reclassified $7.7 million from “EVOMELA IPR&D rights” to “EVOMELA distribution rights” which is presented within “intangible assets, net of accumulated amortization and impairment charges” (see Note 3(f)) within our accompanying Condensed Consolidated Balance Sheets as of September 30, 2018.

We are required to pay Ligand additional amounts of up to $60 million (exclusive of the $6 million milestone paid in April 2016), upon our achievement of specified net sales thresholds. We are also responsible to pay Ligand royalties of 20% on our net sales of EVOMELA in all territories.

(ix) MARQIBO: Acquisition of Talon Therapeutics, Inc. and Related Contingent Consideration Agreement

In July 2013, we completed the acquisition of Talon, through which we obtained exclusive global development and commercialization rights to MARQIBO (see Note 9(a)). As part of this acquisition, the former Talon stockholders have contingent financial rights that we have valued and presented on our accompanying Condensed Consolidated Balance Sheets as a $5.6 million and $6.2 million liability within “acquisition-related contingent obligations” as of September 30, 2018 and December 31, 2017, respectively. The maximum payout value of the contingent financial rights to the former Talon shareholders is $195 million, assuming we achieve all sales and regulatory approval milestones. In addition, we are contractually obligated to pay royalties in the single digits on our net sales of MARQIBO and a portion of sublicensing revenue may be due upon our receipt of such revenue for MARQIBO.

(x) QAPZOLA: License Agreements with Allergan, Inc. and NDDO Research Foundation

In October 2008, we entered into an exclusive development and commercialization collaboration agreement with Allergan, Inc. (“Allergan”) for QAPZOLA pursuant to which Allergan paid us an up-front non-refundable fee of $41.5 million at execution (which we had recognized in full within “license fees and service revenue” by December 31, 2013).

Concurrently we also entered into a letter agreement with NDDO Research Foundation (“NDDO”), pursuant to which we agreed to pay NDDO the following in relation to QAPZOLA milestones: (a) upon FDA acceptance of our NDA, the issuance of 25,000 of our common shares (which occurred in March 2016 and the $0.1 million value of these shares was included in “research and development” expense for the year ended December 31, 2016), and (b) upon FDA approval, a one-time payment of $0.3 million (which has not yet been met, and no amounts have been accrued in our accompanying Consolidated Balance Sheets for its potential achievement).

In January 2013, we entered into a second amendment to the license, development, supply and distribution agreement with Allergan. This amendment relieved Allergan of its development and commercialization obligations and resulted in our acquisition of its rights in the U.S., Europe, and other territories, in exchange for our agreement to pay a tiered single-digit royalty on our sales of certain products containing QAPZOLA.

(xi) QAPZOLA: Collaboration Agreement with Nippon Kayaku Co. LTD.

In November 2009, we entered into a collaboration agreement with Nippon Kayaku Co., LTD. (“Nippon Kayaku”) for the development and commercialization of QAPZOLA in Asia, except North and South Korea (the “Nippon Kayaku Territory”). In addition, Nippon Kayaku received exclusive rights to QAPZOLA for the treatment of Non-Muscle Invasive Bladder Cancer in the Nippon Kayaku Territory, including Japan and China. Nippon Kayaku will conduct QAPZOLA 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 QAPZOLA in the Nippon Kayaku Territory.

Under the terms of this agreement, Nippon Kayaku paid us an upfront fee of $15 million (which we recognized within “license fees and service revenue” in full by December 31, 2013). Under the terms of the agreement, we are entitled to receive $10 million and $126 million from Nippon Kayaku upon the achievement of certain regulatory and commercialization milestones, respectively (some of which are our responsibility to achieve). Nippon Kayaku is also obligated to pay us royalties on its net sales of QAPZOLA in the mid-teen digits.

(xii) BELEODAQ: In-License and Collaboration Agreement with Onxeo

In February 2010, we entered into an in-license and collaboration agreement with TopoTarget A/S (now Onxeo DK) (“Onxeo”), for the development and commercialization of BELEODAQ, as amended in October 2013. We paid Onxeo an upfront fee of $30 million (and agreed to additional payments described below) for rights in North America and India, with an option for China. We are contractually obligated to pay royalties in the mid-teen digits on our net sales of BELEODAQ.

All development and studies of BELEODAQ are conducted under a joint development plan (of which we fund 70% and Onxeo funds 30%). We have final decision-making authority for all developmental activities in North America and India (and China upon exercise of our option). Onxeo has final decision-making authority for all developmental activities in all other jurisdictions. In February 2014, upon FDA acceptance of our NDA, we were contractually obligated to issue Onxeo one million shares of our common stock and to make a $10 million milestone payment. The aggregate value of this milestone at achievement was $17.8 million, and was recognized within “research and development” expense in the first quarter of 2014.

In July 2014, we received approval from the FDA for BELEODAQ’s use for injection and treatment of relapsed or refractory peripheral T-cell lymphoma. As a result, we made a second milestone payment to Onxeo of $25 million in November 2014. This amount was capitalized as “BELEODAQ distribution rights” and is presented within “intangible assets, net of accumulated amortization and impairment charges” (see Note 3(f)). We are also contractually obligated to pay Onxeo upon our achievements of other regulatory events and sales thresholds, up to $88 million and $190 million, respectively. These milestone amounts are not included within “total liabilities” in our accompanying Consolidated Balance Sheets.

(xiii) ROLONTIS: Co-Development and Commercialization Agreement with Hanmi Pharmaceutical Co. Ltd

In October 2014, we exercised our option under a License Option and Research Collaboration Agreement dated January 2012 (as amended) with Hanmi Pharmaceutical Co. Ltd., or Hanmi, for ROLONTIS (formerly referred to as “LAPS-G-CSF” or “SPI-2012”), a drug based on Hanmi’s proprietary LAPSCOVERY™ technology for the treatment of chemotherapy induced neutropenia. Under the terms of this agreement, as amended, we have primary financial responsibility for the ROLONTIS development plan and hold its worldwide rights (except for Korea, China, and Japan). We are contractually obligated to pay Hanmi royalties in the mid-teen digits on our net sales of ROLONTIS.

In January 2016, the first patient was dosed with ROLONTIS in a clinical trial. This triggered our contractual milestone payment to Hanmi, and in April 2016, we (i) issued 318,750 shares of our common stock, then valued at $2.3 million, and (ii) remitted a $0.4 million payment to the Internal Revenue Service (the IRS) on its behalf for related tax obligations. This aggregate $2.7 million value was recognized within “research and development” expense in our Consolidated Statements of Operations for the year ended December 31, 2016. We are responsible for further contractual payments upon our achievement of regulatory and sales milestones, up to $13 million and $225 million, respectively. These amounts are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets.

(xiv) Poziotinib: In-License Agreement with Hanmi and Exclusive Patent and Technology License Agreement with MD Anderson

In February 2015, we executed an in-license agreement with Hanmi for poziotinib, a pan-HER inhibitor in Phase 2 clinical trials, (which has also shown single agent activity in the treatment of various cancer types during Phase I studies, including breast, gastric, colorectal, and lung cancers), and made an upfront payment for these rights. This payment was recognized within “research and development” expense in our Consolidated Statements of Operations for the year ended December 31, 2015. We are also contractually obligated to pay Hanmi royalties in the low to mid-teen digits on our net sales of poziotinib.

Under the terms of this agreement, we received the exclusive rights to commercialize poziotinib, excluding Korea and China. Hanmi and its development partners are fully responsible for the completion of on-going Phase 2 trials in Korea. We are financially responsible for all other clinical studies. We are contractually obligated to make payments to Hanmi upon our achievement of certain regulatory and sales milestones, aggregating $33 million and $325 million, respectively, which are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets. We will pay Hanmi royalties in the low to mid-teen digits on our net sales of poziotinib. These amounts are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets.

In April 2018, we executed an exclusive patent and technology agreement for poziotinib’s use in treating patients with EGFR and HER2 exon 20 mutations in cancer and HER2 exon 19 mutations in cancer with The University of Texas M.D. Anderson Cancer Center (“MD Anderson”) that had discovered its use in treating these patient-types (“Exon 19/20 Patients”). We made an upfront payment of $0.5 million upon this agreement’s execution that was recognized within “research and development” expense in the accompanying Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2018.

We are contractually obligated to make payments to MD Anderson upon our achievement of certain regulatory and sales milestones, aggregating $11 million and $23 million, respectively, which are not included within “total liabilities” in our accompanying Condensed Consolidated Balance Sheets. We will also pay MD Anderson royalties in the low single-digits on our net sales of poziotinib that relate to the treatment of Exon 19/20 Patients.

(xv) ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO: Out-License Agreement with Servier in Canada, Inc. in Canada

In January 2016, we entered into a strategic partnership with Servier Canada, Inc. (“Servier”) for the out-licenses of ZEVALIN, FOLOTYN, BELEODAQ, and MARQIBO. We received an aggregate $6 million of upfront proceeds in the first quarter of 2016, which was recognized within “license fees and service revenue” in our Consolidated Statements of Operations for the year ended December 31, 2016. We are also entitled to milestone receipts (aggregating $2 million) upon Servier’s achievement of specific regulatory approvals, and a high single-digit royalty on its sales of these products.

(c) Service Agreements for our Research and Development Activities

We have entered into various contracts with numerous third party service providers for the execution of our research and development initiatives (to which we assign discreet project codes in order to compile and monitor such expenses). These vendors include raw material suppliers and contract manufacturers for drug products not yet FDA approved, clinical trial sites, clinical research organizations, and data monitoring centers, among others. The financial terms of these agreements are varied and generally obligate us to pay in stages, depending on the achievement of certain events specified in the agreements - such as contract execution, progress of service completion, delivery of drug supply, and the dosing of patients in clinical studies.

We recognize these “research and development” expenses and corresponding “accounts payable and other accrued liabilities” in the accompanying financial statements based on estimates of our vendors’ progress of performed services, patient enrollments and dosing, completion of clinical studies, and other events. Should we decide to discontinue and/or slow-down the work on any project, the associated costs for those projects would typically be limited to the extent of the work completed, as we are generally able to terminate these contracts with adequate notice.

(d) Supply and Service Agreements for our Commercial Products

We have entered into various supply and service agreements, and/or have issued purchase orders, which obligate us to complete agreed-upon raw material purchases from certain vendors for the production of our commercialized drug products through designated contract manufacturers. These commitments do not exceed our planned commercial requirements, and the contracted prices do not exceed current fair market value.

(e) Employment Agreements

We previously entered into an employment agreement with our former Chief Executive Officer, Rajesh C. Shrotriya, M.D., under which cash compensation and benefits would become payable to him in the event of termination by us for any reason other than cause, his resignation for good reason, or upon a change in control of our Company. Effective December 17, 2017, Dr. Shrotriya’s employment was terminated without cause. As of December 31, 2017, we accrued for all contractual cash amounts due and unpaid to him within “accrued payroll and benefits” on the accompanying Condensed Consolidated Balance Sheets.

We entered into new employment agreements with each of our named executive officers (chief executive officer, chief operating officer, chief financial officer, and chief legal officer) in April and June 2018, which supersede any prior Change in Control Severance Agreements with such individuals. These new agreements provide for the payment of certain benefits to each executive upon his separation of employment under specified circumstances. These arrangements are designed to encourage each to act in the best interests of our stockholders at all times during the course of a change in control event or other significant transaction.

(f) Deferred Compensation Plan

The Spectrum Pharmaceuticals, Inc. Deferred Compensation Plan (the “DC Plan”) is administered by the Compensation Committee of our Board of Directors and is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended.

The DC Plan is maintained to provide special benefits for a select group of our employees (the “DC Participants”). DC Participants make annual elections to defer a portion of their eligible cash compensation which is then placed into their DC Plan accounts. We match a fixed percentage of these deferrals, and may make additional discretionary contributions. At September 30, 2018 and December 31, 2017, the aggregate value of this DC Plan liability totaled $6.5 million and $11.0 million, respectively, and is included within “accounts payable and other accrued liabilities” and “other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheets.

(g) Litigation

We are involved from time-to-time with various legal matters arising in the ordinary course of business. These claims and legal proceedings are of a nature we believe are normal and incidental to a pharmaceutical business, and may include product liability, intellectual property, employment matters, and other general claims.

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 assessed 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 consolidated results of operations, cash flows, or financial condition.

Stockholder Litigation

Olutayo Ayeni v. Spectrum Pharmaceuticals, Inc., et al. (Filed September 21, 2016 in the United States District Court, Central District of California; Case No. 2:16-cv-07074) (the “Ayeni Action”) and Glen Hartsock v. Spectrum Pharmaceuticals, Inc., et al. (Filed September 28, 2016 in the United States District Court, District Court of Nevada Case; No. 2:16-cv-02279-RFB-GWF) (the “Hartsock Action”). On November 15, 2016, the Ayeni Action was transferred to the United States District Court for the District of Nevada. The parties have stipulated to a consolidation of the Ayeni Action with the Hartsock Action. These class action lawsuits allege that we and certain of our executive officers made false or misleading statements and failed to disclose material facts about our business and the prospects of approval for our NDA to the FDA for QAPZOLA in violation of Section 10(b) (and Rule 10b-5 promulgated thereunder) and 20(a) of the Securities Exchange Act of 1934, as amended. The plaintiffs seek damages, interest, costs, attorneys’ fees, and other unspecified equitable relief. We believe that these claims are without merit, and intend to vigorously defend against these claims. Furthermore, as of September 30, 2018, the value of a potential settlement cannot be reasonably estimated given its highly uncertain nature.

EVOMELA Litigation

We obtained global development and commercialization rights to EVOMELA from CyDex Pharmaceuticals, Inc., a wholly-owned subsidiary of Ligand Pharmaceuticals Incorporated, or CyDex, in March 2013. We thereafter assumed responsibility for completing its clinical trials and were responsible for filing the New Drug Application. Under our license agreement with CyDex, CyDex received a license fee and is eligible to receive milestone payments and royalties. On December 20, 2017, CyDex filed an action against Teva Pharmaceuticals USA, Inc., TEVA Pharmaceuticals Industries Ltd., and Actavis, LLC, together Teva, in the U.S. District Court for the District of Delaware, alleging patent infringement with respect to a paragraph IV certification, or an Abbreviated New Drug Application (“ANDA”), filed with the FDA seeking approval to market a generic version of EVOMELA. CyDex brought suit against Teva to protect its intellectual property rights.”

Intellectual Property Litigation

We and Onxeo received a Paragraph IV Notice Letter dated August 21, 2018, notifying us that Fresenius Kabi USA, LLC (“Fresenius”) has submitted to the FDA, an ANDA seeking approval from the FDA to manufacture and market a generic version of BELEODAQ (belinostat) for injection in the U.S. We and Onxeo have filed a patent infringement lawsuit against Fresenius which triggered an automatic stay of this ANDA for 30 months. In addition, BELOEDAQ is protected from competition in the U.S. by an Orphan Drug Exclusivity indication until July 3, 2021.

Income Taxes

9 Months Ended

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

We apply an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods, as required under GAAP. We recorded a provision for income taxes of $8 thousand and a benefit for income taxes of $1.4 million for the nine months ended September 30, 2018 and 2017, respectively. Our ETR differs from the U.S. federal statutory tax rate of 21% primarily as a result of nondeductible expenses, state income taxes, foreign income taxes, and the impact of a valuation allowance on our deferred tax assets.

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. We recognize the impact of a tax position in our financial statements only if that position is more likely than not to be 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.

The intraperiod tax allocation rules require that we allocate the “(provision) benefit for income taxes” between continuing operations and other categories of earnings. In prior periods where we have a year-to-date pre-tax loss from continuing operations and year-to-date pre-tax income in other categories of earnings, such as other comprehensive income, ASC 740-20-45-7 requires that we allocate the income tax provision to other categories of earnings, and then record a related tax benefit in continuing operations. For the three and nine months ended September 30, 2017, we recognized net income from investments and currency transactions within “other comprehensive income” while sustaining losses from continuing operations. As a result of the required allocation under ASC 740-20-45-7, we recorded tax expense of $2.1 and $2.1 million in “other comprehensive income” on the accompanying Condensed Consolidated Statements of Comprehensive Loss, and a benefit for income taxes of $1.5 million and $1.4 million within “benefit for income taxes” on the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017, respectively. Beginning January 1, 2018, as a result of the adoption of ASU 2016-01 Recognition and Measurement of Financial Assets and Liabilities, and related reclassification of gains on investments in equity securities to the Consolidated Statements of Operations, we have recognized currency translation losses in our Condensed Consolidated Statement of Comprehensive Income (Loss). Thus, during the three and nine months ended September 30, 2018, there has been no allocation of tax benefits to the Condensed Consolidated Statements of Operations pursuant to the required allocations under ASC 740-20-45-7.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning in 2018, the transition of U.S. international taxation from a worldwide tax system to a territorial system, which includes a new federal tax on global intangible low-taxed income (Global Minimum Tax, or GMT), and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017.

The SEC Staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

At December 31, 2017, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments. The provisional amounts described below are subject to revisions as we complete our analysis of the Tax Act, collect data, and interpret any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, or IRS, FASB, and other standard-setting and regulatory bodies. Adjustments to the provisional amounts may materially impact our consolidated income tax provision (benefit) and effective tax rates in the period(s) in which such adjustments are made. Our accounting for the tax effects of the Tax Act will be completed during the one-year measurement period.

Reduction of U.S. Federal Corporate Tax Rate: For certain of our deferred tax assets and deferred tax liabilities, we have recorded a provisional decrease in net deferred tax assets of $38.9 million, with a corresponding decrease in the valuation allowance of $41.4 million and a benefit to income tax expense of $2.5 million for the year ended December 31, 2017. This provisional estimate may be affected by other analyses related to the Tax Act, including, but not limited to, the state tax effect of adjustments made to federal temporary differences.

Deemed Repatriation Transition Tax: Based upon our preliminary analysis, we have concluded that a net accumulated E&P deficit exists as of December 31, 2017 for our foreign subsidiaries. As a result, we did not accrue any provisional transition tax liabilities. We will continue to gather additional and perform additional analyses to more precisely determine past foreign earnings and related taxes and will update our provisional estimate with respect to the transition tax liability when such work is completed within the one-year measurement period.

Valuation Allowance: The Tax Act limits the amount taxpayers are able to deduct for net operating loss carryforwards generated in taxable years beginning after December 31, 2017 to 80% of the taxpayer’s taxable income. However, net operating loss carryforwards generated in taxable years ending after December 31, 2017 can be carried forward indefinitely. A taxable temporary difference associated with an indefinite-lived asset is generally considered to be a source of taxable income to support realization of a net operating loss with an unlimited carryforward period. Due to the restriction on the ability to use the net operating loss with unlimited carryforward periods arising in taxable years beginning after December 31, 2017, only 80% of the indefinite-lived taxable temporary difference would serve as a source of taxable income. As a result, the valuation allowance decreased by $2.9 million related to the 80% utilization of the indefinite-lived taxable temporary as a source of taxable income.

Under GAAP, we are allowed to make an accounting policy choice with respect to the GMT of either (1) treating taxes due on future U.S. inclusions in taxable income related to GMT as a current-period expense when incurred or (2) as a component of deferred income taxes. We will make our accounting policy election for this item when our analysis is complete, during the measurement period.

Due to the valuation allowance on our deferred tax assets, there was no net impact to the tax provision for income taxes arising from the Tax Act for the three and nine months ended September 30, 2018.

Sale of Common Stock Under ATM Agreements

In December 2015 and August 2017, we entered into collective at-market-issuance sales agreements with FBR Capital Markets & Co., MLV & Co. LLC, and H.C. Wainwright & Co., LLC. (the “December 2015 ATM Agreement” and the “August 2017 ATM Agreement”, respectively). These agreements allowed us to raise aggregate gross proceeds through these brokers of up to $250 million from the sale of our common stock on the public market.

Through September 30, 2018, we had raised aggregate gross net proceeds of $202.1 million through these at-market sales, of which $128.3 million was raised during the year ended December 31, 2017. We are using these proceeds to continue to develop our product pipeline and to provide additional capital structure flexibility.

We sold and issued shares of our common stock under both the December 2015 ATM Agreement and August 2017 ATM Agreement, summarized as follows:

Description of Financing Transaction	No. of Common Shares Issued	Proceeds Received (Net of Broker Commissions and Fees )
Common shares issued pursuant to the December 2015 ATM Agreement during the year ended December 31, 2016	10,890,915	$	73,869

Immaterial Restatement Of Prior Period Financial Statements For Stock-Based Compensation

Accounting Changes and Error Corrections [Abstract]

Immaterial Restatement Of Prior Period Financial Statements For Stock-Based Compensation

IMMATERIAL RESTATEMENT OF PRIOR PERIOD FINANCIAL STATEMENTS FOR STOCK-BASED COMPENSATION

Subsequent to the issuance of our unaudited interim financial statements for the quarter and year-to-date periods ended September 30, 2017, our management identified certain immaterial errors within previously reported operating expense captions of “selling, general, and administrative” and “research and development” that solely relate to our stock-based compensation recognition (see Note 6). These errors were primarily the result of an improper system setting during our 2012 implementation of our then-new stock-based compensation software. Consequently, incremental expense for the reversal of previously applied forfeiture estimates was not timely recognized upon the full vesting of each award, as required; this error persisted through September 30, 2017. We considered these errors from a qualitative and quantitative perspective, and concluded they were not material to each prior period. However, we have restated our accompanying Condensed Consolidated Financial Statements to correct for these immaterial errors for the prior-year interim period presented.

Restated Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2017:

New Revenue Recognition Standard

NEW REVENUE RECOGNITION STANDARD

As discussed in Note 2(i), Topic 606 became effective for us on January 1, 2018. We applied the “modified retrospective” transition method for the accounting of open contracts at implementation. This resulted in the recognition of an aggregate $4.7 million increase to our January 1, 2018 retained earnings (for the tax-effected cumulative impact of initially applying this new standard, with no adjustments to our prior period financial statements). Our prior periods continue to be presented in accordance with our historical revenue accounting practices under Topic 605.

Had we continued to apply Topic 605 for our revenue recognition for the three and nine months ended September 30, 2018, the “pro forma” impact to our Condensed Consolidated Statements of Operations is presented in the table below:

Accounting Policies [Abstract]

Description of Business

Description of Business

Spectrum Pharmaceuticals, Inc. (“Spectrum”, the “Company”, “we”, “our”, or “us”) is a biopharma company, with a primary strategy comprised of acquiring, developing, and commercializing a broad and diverse pipeline of late-stage clinical and commercial products. We have an in-house clinical development organization with regulatory and data management capabilities, in addition to commercial infrastructure and a field-based sales force for our marketed products. Currently, we have six approved oncology/hematology products (FUSILEV, FOLOTYN, ZEVALIN, MARQIBO, BELEODAQ, and EVOMELA) that target different types of cancer including: non-Hodgkin’s lymphoma (“NHL”), advanced metastatic colorectal cancer, acute lymphoblastic leukemia, and multiple myeloma (“MM”).

We also have two drugs in mid-to-late stage development (in Phase 2 or Phase 3 clinical trials):

• poziotinib, a novel pan-HER inhibitor used in the treatment of patients with a variety of solid tumors, including breast and lung cancer; and

• ROLONTIS for chemotherapy-induced neutropenia.

Basis of Presentation

Basis of Presentation

Interim Financial Statements

The interim financial data for the three and nine months ended September 30, 2018 and 2017, respectively, is unaudited, and is not necessarily indicative of our operating results for a full year. In the opinion of our management, the interim data includes normal and recurring adjustments necessary for a fair presentation of our financial results for the three and nine months ended September 30, 2018 and 2017. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the U.S. Securities and Exchange Commission (“SEC”) rules and regulations relating to interim financial statements. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements and Notes thereto included within our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (filed with the SEC on March 7, 2018).

Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and with the rules and regulations of the SEC. These financial statements include the financial position, results of operations, and cash flows of Spectrum and its subsidiaries, all of which are wholly-owned (except for Spectrum Pharma Canada (“SPC”), as discussed below). All inter-company accounts and transactions among these legal entities have been eliminated in consolidation.

Variable Interest Entity

We own fifty-percent of SPC, a legal entity organized in Quebec, Canada in January 2008. Some of our clinical studies are conducted through this “variable interest entity” (as defined under applicable GAAP). We fund all of SPC’s operating costs, and since we assume all risks and rewards for this entity, we meet the criteria as being its “primary beneficiary” (as defined under applicable GAAP). Accordingly, SPC’s balance sheets and statements of operations are included in our Condensed Consolidated Financial Statements as if it were a wholly-owned subsidiary for all periods presented.

Operating Segment

Operating Segment

We operate in one reportable operating segment that is focused exclusively on developing and marketing oncology and hematology drug products. For the three and nine months ended September 30, 2018 and 2017, all of our revenue and related expenses were solely attributable to these activities. Substantially all of our assets (excluding cash held in certain foreign bank accounts and ZEVALIN distribution rights for ex-U.S. territories - see Note 3(f)) are held in the U.S.

Revenue Recognition

Revenue Recognition

Impact of the Adoption of the New Revenue Recognition Standard:ASU No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), became effective for us on January 1, 2018. Our disclosure within the below sections to this footnote reflects our updated accounting policies that are affected by this new standard. We applied the “modified retrospective” transition method for open contracts for the implementation of Topic 606; thisresulted in the recognition of an aggregate $4.7 million, net of tax, decrease to our January 1, 2018 “accumulated deficit” on our accompanying Condensed Consolidated Balance Sheets for the cumulative impact of applying this new standard. We made no adjustments to our previously-reported total revenues, as those periods continue to be presented in accordance with our historical accounting practices under Topic 605, Revenue Recognition (“Topic 605”). See Notes 4, 5, and 19 for additional quantitative and qualitative revenue disclosures in accordance with Topic 606.

Required Elements of Our Revenue Recognition: Revenue from our (a) product sales, (b) out-license arrangements, and (c) service arrangements is recognized under Topic 606 in a manner that reasonably reflects the delivery of our goods and/or services to customers in return for expected consideration and includes the following elements:

(1) we ensure that we have an executed contract(s) with our customer that we believe is legally enforceable;

(2) we identify the “performance obligations” in the respective contract;

(3) we determine the “transaction price” for each performance obligation in the respective contract;

(4) we allocate the transaction price to each performance obligation; and

(5) we recognize revenue only when we satisfy each performance obligation.

    These five elements, as applied to each of our revenue categories, are summarized below:

(a) Product Sales: We sell our products to pharmaceutical wholesalers/distributors (i.e., our customers), except for our U.S. sales of ZEVALIN in which case the end-user (i.e., clinic or hospital) is our customer. Our wholesalers/distributors in turn sell our products directly to clinics, hospitals, and private oncology-based practices. Revenue from our product sales is recognized as physical delivery of product occurs (when our customer obtains control of the product), in return for agreed-upon consideration.

Our gross product sales (i.e., delivered units multiplied by the contractual price per unit) are reduced by our corresponding gross-to-net (“GTN”) estimates using the “expected value” method, resulting in our reported “product sales, net” in the accompanying Condensed Consolidated Statements of Operations, reflecting the amount we ultimately expect to realize in net cash proceeds, taking into account our current period gross sales and related cash receipts, and the subsequent cash disbursements on these sales that we estimate for the various GTN categories discussed below. These estimates are based upon information received from external sources (such as written or oral information obtained from our customers with respect to their period-end inventory levels and sales to end-users during the period), in combination with management’s informed judgments. Due to the inherent uncertainty of these estimates, the actual amount incurred (of some, or all) of product returns, government chargebacks, prompt pay discounts, commercial rebates, Medicaid rebates, and distribution, data, and GPO administrative fees may be materially above or below the amount estimated, then requiring prospective adjustments to our reported net product sales.

These GTN estimate categories are each discussed below:

Product Returns Allowances: Our FUSILEV, MARQIBO, and BELEODAQ customers are contractually permitted to return purchased products beginning at its expiration date and within six months thereafter. Our EVOMELA customers are permitted to return purchased product beginning at six months prior to its expiration date, and within 12 months thereafter (as well as for overstock inventory, as determined by end-users). ZEVALIN and FOLOTYN returns for expiry are not contractually permitted. Returns outside of this aforementioned criteria are not customarily allowed. We estimate expected product returns for our allowance based on our historical return rates. Returned product is typically destroyed, since substantially all returns are due to expiry and cannot be resold.

Government Chargebacks: Our products are subject to pricing limits under certain federal government programs (e.g., Medicare and 340B Drug Pricing Program). Qualifying entities (i.e., end-users) purchase products from our customers at their qualifying discounted price. The chargeback amount we incur represents the difference between our contractual sales price to our customer, and the end-user’s applicable discounted purchase price under the government program. There may be significant lag time between our reported net product sales and our receipt of the corresponding government chargeback claims from our customers.

Prompt Pay Discounts: Discounts for prompt payment are estimated at the time of sale, based on our eligible customers’ prompt payment history and the contractual discount percentage.

Commercial Rebates: Commercial rebates are based on (i) our estimates of end-user purchases through a group purchasing organization (“GPO”), (ii) the corresponding contractual rebate percentage tier we expect each GPO to achieve, and (iii) our estimates of the impact of any prospective rebate program changes made by us.

Medicaid Rebates: Our products are subject to state government-managed Medicaid programs, whereby rebates are issued to participating state governments. These rebates arise when a patient treated with our product is covered under Medicaid, resulting in a discounted price for our product under the applicable Medicaid program. Our Medicaid rebate accrual calculations require us to project the magnitude of our sales, by state, that will be subject to these rebates. There is a significant time lag in us receiving rebate notices from each state (generally several months or longer after our sale is recognized). Our estimates are based on our historical claim levels by state, as supplemented by management’s judgment.

Distribution, Data, and GPO Administrative Fees: Distribution, data, and GPO administrative fees are paid to authorized wholesalers/distributors of our products (except for U.S. sales of ZEVALIN) for various commercial services including: contract administration, inventory management, delivery of end-user sales data, and product returns processing. These fees are based on a contractually-determined percentage of our applicable sales.

(b) License Fees: Our out-license arrangements allow licensees to market our product(s) in certain territories for a specific term (representing the out-license of “functional intellectual property”). These arrangements may include one or more of the following forms of consideration: (i) upfront license fees, (ii) sales royalties, (iii) sales milestone-achievement fees, and (iv) regulatory milestone-achievement fees. We recognize revenue for each based on the contractual terms that establish our right to collect payment once the performance obligation is achieved, as follows:

(1) Upfront License Fees: We determine whether upfront license fees are earned at the time of contract execution (i.e., when rights transfer to the customer) or over the actual (or implied) contractual period of the out-license. As part of this determination, we evaluate whether we have any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer. Our customers’ “distinct” rights to licensed “functional intellectual property” at the time of contract execution results in concurrent revenue recognition of all upfront license fees (assuming that there are no other performance obligations at contract execution that are inseparable from this license transfer).

(2) Royalties: Under the “sales-or-usage-based royalty exception” we recognize revenue in the same period that our

licensees complete product sales in their territory for which we are contractually entitled to a percentage-based royalty receipt.

(3) Sales Milestones: Under the “sales-or-usage-based royalty exception” we recognize revenue in full within the period that our licensees achieve annual or aggregate product sales levels in their territories for which we are contractually entitled to a specified lump-sum receipt.

(4) Regulatory Milestones: Under the terms of the respective out-license, regulatory achievements may either be our responsibility, or that of our licensee.

• When our licensee is responsible for the achievement of the regulatory milestone, we recognize revenue in full (for the contractual amount due from our licensee) in the period that the approval occurs (i.e., when the “performance obligation” is satisfied by our customer) under the “most likely amount” method. This revenue recognition remains “constrained” (i.e., not recognized) until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

• When we are responsible for the achievement of a regulatory milestone, the “relative selling price method” is applied for purposes of allocating the transaction price to our performance obligations. In such case, we consider (i) the extent of our effort to achieve the milestone and/or the enhancement of the value of the delivered item(s) as a result of milestone achievement and (ii) if the milestone payment is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. We have historically assessed the contractual value of these milestones upon their achievement to be identical to the allocation of value of our performance obligations and thus representing the “transaction price” for each milestone at contract inception. We recognize this revenue in the period that the regulatory approval occurs (i.e., when we complete the “performance obligation”) under the “most likely amount” method, and revenue recognition is otherwise “constrained” until regulatory approval occurs, given its inherent uncertainty and the requirement of a significant revenue reversal not being probable if achievement does not occur. At each reporting period, we re-evaluate the probability of milestone achievement and the associated revenue constraint; any resulting adjustments would be recorded on a cumulative catch-up basis, thus reflected in our financial statements in the period of adjustment.

(c) Service Revenue: We receive fees under certain arrangements for (i) sales and marketing services, (ii) supply chain services, (iii) research and development services, and (iv) clinical trial management services.

Our rights to receive payment for these services may be established by (1) a fixed-fee schedule that covers the term of the arrangement, so long as we meet ongoing performance obligations, (2) our completion of product delivery in our capacity as a procurement agent, (3) the successful completion of a phase of drug development, (4) favorable results from a clinical trial, and/or (5) regulatory approval events.

We consider whether revenue associated with these service arrangements is reportable each period, based on our completed services or deliverables (i.e., satisfied “performance obligations”) during the reporting period, and the terms of the arrangement that contractually result in fixed payments due to us. The promised service(s) within these arrangements are distinct and explicitly stated within each contract, and our customer benefits from the separable service(s) delivery/completion. Further, the nature of the promise to our customer as stated within the respective contract is to deliver each named service individually (not a transfer of combined items to which the promised goods or services are inputs), and thus are separable for revenue recognition.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist of bank deposits and highly liquid investments with maturities of three months or less from the purchase date.

Marketable Securities

Marketable Securities

Our marketable securities consist of our holdings in equity securities (beginning January 1, 2018 - see Note 3(a)), mutual funds, and bank certificates of deposit (“Bank CDs”). Beginning January 1, 2018, our realized and unrealized (losses) gains on marketable securities are included in “Other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations. Prior to January 1, 2018, our unrealized (losses) gains were included in “other comprehensive (loss) income” on our accompanying Condensed Consolidated Statements of Comprehensive Loss.

Accounts Receivable

Accounts Receivable

Our accounts receivable are derived from our product sales and license fees (our service revenue is recorded in “other receivables”), and do not bear interest. The allowance for doubtful accounts is management’s best estimate of the amount of probable credit losses in our existing accounts receivable. Account balances are charged off against the allowance after appropriate collection efforts are exhausted.

Inventories

Inventories

We value our inventory at the lower of (i) the actual cost of its purchase or manufacture, or (ii) its net realizable value. Inventory cost is determined on the first-in, first-out method. We regularly review our inventory quantities in process of manufacture and on hand. When appropriate, we record a provision for obsolete and excess inventory to derive its new cost basis, which takes into account our sales forecast by product and corresponding expiry dates of each product lot.

Manufacturing costs of drug products that are pending U.S. Food and Drug Administration (“FDA”) approval are expensed through “research and development,” on the accompanying Condensed Consolidated Statements of Operations (rather than being capitalized to “inventories”).

Property and Equipment

Property and Equipment

Our property and equipment is stated at historical cost, and is depreciated on a straight-line basis over an estimated useful life that corresponds with its designated asset category. We evaluate the recoverability of “long-lived assets” (which includes property and equipment) whenever events or changes in circumstances in our business indicate that the asset’s carrying amount may not be recoverable through our on-going operations.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Our goodwill represents the excess of our business acquisition cost over the estimated fair value of the net assets acquired in the corresponding transaction. Goodwill has an indefinite accounting life and is therefore not amortized. Instead, goodwill is evaluated for impairment on an annual basis (as of each October 1st), unless we identify impairment indicators that would require earlier testing.

We evaluate the recoverability of indefinite-lived intangible assets at least annually, or whenever events or changes in our business indicate that an intangible asset’s (whether indefinite or definite-lived) carrying amount may not be recoverable. Such circumstances could include, but are not limited to the following:

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

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

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

Intangible assets with finite useful lives are amortized over their estimated useful lives on a straight-line basis. We review these assets for potential impairment if/when facts or circumstances suggest that the carrying value of these assets may not be recoverable.

Stock-Based Compensation

Stock-Based Compensation

Stock-based compensation expense for equity awards granted to our employees and members of our Board of Directors is recognized on a straight-line basis over each award’s vesting period. Recognized compensation expense is net of an estimated forfeiture rate, representing the percentage of awards that are expected to be forfeited prior to vesting, though is ultimately adjusted for actual forfeitures. We use the Black-Scholes option pricing model to determine the fair value of stock options (as of the date of grant) that have service conditions for vesting. We use the Monte Carlo valuation model to value equity awards (as of the date of grant) that have combined market conditions and service conditions for vesting.

The recognition of stock-based compensation expense and the initial calculation of stock option fair value requires uncertain assumptions, including (a) the pre-vesting forfeiture rate of the award, (b) the expected term that the stock option will remain outstanding, (c) our stock price volatility over the expected term (and that of our designated peer group with respect to certain market-based awards), and (d) the prevailing risk-free interest rate for the period matching the expected term.

With regard to (a)-(d): We estimate forfeiture rates based on our employees’ overall forfeiture history, which we believe will be representative of future results. We estimate the expected term of stock options granted based on our employees’ historical exercise patterns, which we believe will be representative of their future behavior. We estimate the volatility of our common stock on the date of grant based on the historical volatility of our common stock for a look-back period that corresponds with the expected term. We estimate the risk-free interest rate based upon the U.S. Department of the Treasury yields in effect at award grant, for a period equaling the expected term of the stock option.

Foreign Currency Translation

Foreign Currency Translation

Our foreign subsidiaries’ separate financial statements are stated in their functional currencies (i.e., local operating currencies). To create the accompanying Condensed Consolidated Financial Statements, we translate the assets and liabilities of our subsidiaries to U.S. dollars at the rates of exchange in effect at the reported balance sheet date; revenues and expenses are translated using the monthly average exchange rates during the reported period. Unrealized gains and losses from these translations are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

We record foreign currency-based transactions (i.e., when not denominated in the functional currency of our transacting legal entity) at the prevailing exchange rate on the date of the transaction. Resulting unrealized foreign exchange gains and losses from these unsettled transactions are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets.

All unrealized foreign exchange gains and losses associated with our intercompany loans are included in “accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheets, as these loans with our foreign subsidiaries are not expected to be settled in the “foreseeable future.”

Basic and Diluted Net Loss per Share

Basic and Diluted Net Loss per Share

We calculate basic and diluted net loss per share using the weighted average number of common shares outstanding during the periods presented. In periods of a net loss, 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 only dilutive stock options, warrants, and other common stock equivalents outstanding during the period.

Income Taxes

Income Taxes

Deferred tax assets and liabilities are recorded based on the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain.

We have recorded a valuation allowance to reduce our deferred tax assets, because we believe that, based upon a weighting of positive and negative factors, it is more likely than not that these deferred tax assets will not be realized. If/when we were to determine that our deferred tax assets are realizable, an adjustment to the corresponding valuation allowance would increase our net income in the period that such determination was made.

In the event that we are assessed interest and/or penalties from taxing authorities that have not been previously accrued, such amounts would be included in “(provision) benefit for income taxes” within the Condensed Consolidated Statements of Operations for the period in which we received the notice.

Research and Development Costs

Research and Development Costs

Our research and development costs are expensed as incurred (see Note 15(c)), or as certain milestone payments become contractually due to our licensors, as triggered by the achievement of clinical or regulatory events.

New Accounting Standard for Leases

New Accounting Standard for Leases, effective January 1, 2019

In February 2016, the FASB issued ASU 2016-02, which amends the FASB Accounting Standards Codification and creates Topic 842, Leases (“Topic 842”). The new topic supersedes Topic 840, Leases and requires additional disclosures regarding our lease arrangements, as well as our presentation of lease assets and lease liabilities (including those for operating leases) on the balance sheet at the present value of lease payments not yet paid, and for us to subsequently apply the “effective interest rate” method” to reduce the lease liability, while amortizing the right-of-use asset for straight-line expense recognition over the lease term.

Topic 842 is effective for us beginning January 1, 2019, and mandates a “modified retrospective” transition method. We are currently assessing the quantitative impact this guidance will have on our consolidated financial statements. However, we presently do not have any capital lease arrangements, or any active contracts that would contain an “embedded lease”. Our current operating lease arrangements affected by this “gross-up” presentation are limited to (1) our executive, administrative, and research and development office facilities and (2) certain office equipment.

Fair Value Measurements

Fair Value Measurements

We determine measurement-date fair value based on the proceeds that would be received through the sale of the asset, or that we would pay to settle or transfer the liability, in an orderly transaction between market participants. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. 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 publicly accessible at the measurement date.

Level 2: Observable prices that are based on inputs not quoted on active markets, but that are corroborated by market data. These inputs may include quoted prices for similar assets or liabilities or quoted market prices in markets that are not active to the general public.

Level 3: Unobservable inputs are used when little or no market data is available.

* Beginning January 1, 2018, under the new requirements of ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities, the unrealized (losses) gains on our CASI Pharmaceuticals, Inc. (NASDAQ: CASI) (“CASI”) equity securities are recognized as a (decrease) increase to “other (expense) income, net” on the Consolidated Statements of Operations (rather than through “other comprehensive (loss) income” on the Consolidated Statements of Comprehensive Loss). Our adoption of ASU 2016-01 on January 1, 2018, resulted in a $17.2 million cumulative-effect adjustment, net of income tax, recorded as a decrease to “accumulated other comprehensive (loss) income” and a decrease to “accumulated deficit” on the accompanying Condensed Consolidated Balance Sheets. Our recognized unrealized loss on these equity securities for the three months ended September 30, 2018 was $40.9 million and our recognized unrealized gain on these equity securities for the nine months ended September 30, 2018 was $17.7 million, as reported in “other (expense) income, net” on the accompanying Condensed Consolidated Statements of Operations.

(1) Beginning June 2016, we adjusted the amortization period of our FOLOTYN distribution rights to November 2022 from March 2025, representing the period through which we expect to have patent protection from generic competition.

(2) On February 20, 2015, the United States District Court for the District of Nevada found the patent covering FUSILEV to be invalid, which was upheld on appeal. On April 24, 2015, Sandoz began to commercialize a generic version of FUSILEV. This represented a “triggering event” under applicable GAAP in evaluating the value of our FUSILEV distribution rights as of March 31, 2015, resulting in a recognized $7.2 million impairment charge (non-cash) in 2015. We accelerated amortization expense recognition in 2015 for the then remaining net book value of FUSILEV distribution rights.

(3) On May 29, 2013, we amended our FOLOTYN collaboration agreement with Mundipharma. As a result of the amendment, Europe and Turkey were excluded from Mundipharma’s commercialization territory, and their royalty rates and milestone payments to us were modified. This constituted a change under which we originally valued the FOLOTYN out-license as part of business combination accounting, resulting in a recognized impairment charge (non-cash) of $1 million in 2013.
