We are developing a pipeline of drug candidates that utilize our advanced polymer conjugate technology platforms, which are designed to enable the development of new molecular entities that target known mechanisms of action. Our research and development pipeline of new investigational drugs includes treatments for cancer, autoimmune disease and chronic pain. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Our research and development activities have required significant ongoing investment to date and are expected to continue to require significant investment. As a result, we expect to continue to incur substantial losses and negative cash flows from operations in the future. We have financed our operations primarily through cash generated from licensing, collaboration and manufacturing agreements and financing transactions. At March 31, 2019, we had approximately $1.8 billion in cash and investments in marketable securities and debt of $250.0 million in principal of senior secured notes due in October 2020. &lt;/p&gt;

All intercompany accounts and transactions have been eliminated in consolidation.&lt;/p&gt;

As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. generally accepted accounting principles (GAAP) for annual periods can be condensed or omitted. In the opinion of management, these financial statements include all normal and recurring adjustments that we consider necessary for the fair presentation of our financial position and operating results.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Our Condensed Consolidated Financial Statements are denominated in U.S. dollars. Accordingly, changes in exchange rates between the applicable foreign currency and the U.S. dollar will affect the translation of each foreign subsidiary&amp;#8217;s financial results into U.S. dollars for purposes of reporting our consolidated financial results. Translation gains and losses are included in accumulated other comprehensive loss in the stockholders&amp;#8217; equity section of the Condensed Consolidated Balance Sheets. To date, such cumulative currency translation adjustments have not been significant to our consolidated financial position.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Our comprehensive loss consists of our net loss plus our foreign currency translation gains and losses and unrealized holding gains and losses on available-for-sale securities, neither of which were significant during the three months ended March 31, 2019 and 2018. In addition, there were no significant reclassifications out of accumulated other comprehensive loss to the statements of operations during the three months ended March 31, 2019 and 2018.&lt;/p&gt;

The Condensed Consolidated Balance Sheet data as of December&amp;#160;31, 2018 was derived from the audited consolidated financial statements which are included in our Annual Report on Form&amp;#160;10-K for the year ended December&amp;#160;31, 2018 filed with the SEC on March 1, 2019. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and the accompanying notes to those financial statements included in our Annual Report on Form 10-K for the year ended December&amp;#160;31, 2018.&lt;/p&gt;

Accounting estimates and assumptions are inherently uncertain. Actual results could differ materially from those estimates and assumptions. Our estimates include those related to estimated selling prices of performance obligations and estimates of variable consideration in collaboration agreements, estimated royalty revenue, other estimates required for revenue recognition as described further below, the net realizable value of inventory, the impairment of investments, goodwill and long-lived assets, contingencies, accrued clinical trial, contract manufacturing and other expenses, estimated non-cash royalty revenue and non-cash interest expense from our liability related to our sale of future royalties, stock-based compensation, and ongoing litigation, among other estimates. We base our estimates on historical experience and on other assumptions that management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources. As appropriate, estimates are assessed each period and updated to reflect current information and any changes in estimates will generally be reflected in the period first identified.&lt;/p&gt;

Such reclassifications do not materially impact previously reported revenue, operating loss, net loss, total assets, liabilities or stockholders&amp;#8217; equity. &lt;/p&gt;

Our accounts receivable balance contains billed and unbilled trade receivables from product sales, milestones, other contingent payments and royalties, as well as reimbursable costs from collaborative research and development agreements. As of March 31, 2019, our accounts receivable includes $14.5 million from contracts with customers and $28.4 million for net expense reimbursements from our collaboration partner. As of December 31, 2018, our accounts receivable includes $24.2 million from contracts with customers and $19.0 million for expense reimbursements from our collaboration partner. We generally do not require collateral from our customers. We perform a regular review of our customers&amp;#8217; credit risk and payment histories, including payments made after period-end. When appropriate, we provide for an allowance for doubtful accounts by reserving for specifically identified doubtful accounts, although historically we have not experienced credit losses from our accounts receivable.&lt;/p&gt;

In certain cases, we rely on single sources of supply of one or more critical materials. Consequently, in the event that supplies are delayed or interrupted for any reason, our ability to develop and produce our drug candidates or our ability to meet our supply obligations could be significantly impaired, which could have a material adverse effect on our business, financial condition and results of operations.&lt;/p&gt;

&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;On January 1, 2019, we adopted Accounting Standards Codification (ASC) 842, &lt;font style="font-style:italic;"&gt;Leases &lt;/font&gt;(ASC 842). ASC 842 supersedes the guidance in ASC 840, &lt;font style="font-style:italic;"&gt;Leases &lt;/font&gt;(ASC 840). &lt;font style="color:#000000;"&gt;Under ASC 842, an entity recognizes a right-of-use asset and a corresponding lease liability, measured as the present value of the lease payments, for leases with terms greater than one year. &lt;/font&gt;In our adoption, we used the package of practical expedients, which among other things, allowed us to carry forward the historical lease classification of those leases in effect as of January 1, 2019. We present results for the three months ended March 31, 2019 under ASC 842. We have not restated the results for the three months ended March 31, 2018 and continue to report them under ASC 840.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;As a result of the adoption of ASC 842 on January 1, 2019, we recorded right-of-use assets of $83.5 million and lease liabilities of $96.2 million with no cumulative effect adjustment to accumulated deficit. Our lease arrangements are further described in Note 4.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Collaborative Arrangements&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We enter into collaboration arrangements with pharmaceutical and biotechnology collaboration partners, under which we may grant licenses to our collaboration partners to further develop and commercialize one of our proprietary drug candidates, either alone or in combination with the collaboration partners&amp;#8217; compounds, or grant licenses to partners to use our technology to research and develop their own proprietary drug candidates. We may also perform research, development, manufacturing and supply activities under our collaboration agreements. Consideration under these contracts may include an upfront payment, development milestones and other contingent payments, expense reimbursements, royalties based on net sales of approved drugs, and commercial sales milestone payments. Additionally, these contracts may provide options for the customer to purchase our proprietary PEGylation materials, drug candidates or additional contract research and development services under separate contracts. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;When we enter into collaboration agreements, we assess whether the arrangements fall within the scope of ASC 808, &lt;font style="font-style:italic;"&gt;Collaborative Arrangements&lt;/font&gt; (ASC 808) based on whether the arrangements involve joint operating activities and whether both parties have active participation in the arrangement and are exposed to significant risks and rewards. To the extent that the arrangement falls within the scope of ASC 808, we assess whether the payments between us and our collaboration partner fall within the scope of other accounting literature. If we conclude that payments from the collaboration partner to us represent consideration from a customer, such as license fees and contract research and development activities, we account for those payments within the scope of ASC 606, &lt;font style="font-style:italic;"&gt;Revenue from Contracts with Customers&lt;/font&gt; (ASC 606). However, if we conclude that our collaboration partner is not a customer for certain activities and associated payments, such as for certain collaborative research, development, manufacturing and commercial activities, we present such payments as a reduction of research and development expense or general and administrative expense, based on where we present the underlying expense. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Revenue Recognition&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;For elements of those arrangements that we determine should be accounted for under ASC 606, we assess which activities in our collaboration agreements are performance obligations that should be accounted for separately and determine the transaction price of the arrangement, which includes the assessment of the probability of achievement of future milestones and other potential consideration. For arrangements that include multiple performance obligations, such as granting a license or performing contract research and development activities or participation on joint steering or other committees, we allocate upfront and milestone payments under a relative standalone selling price method. Accordingly, we develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. These key assumptions may include revenue forecasts, clinical development timelines and costs, discount rates and probabilities of clinical and regulatory success.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;Product Sales&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Product sales are primarily derived from manufacturing and supply agreements with our customers. We have assessed our current manufacturing and supply arrangements and have generally determined that they provide the customer an option to purchase our proprietary PEGylation materials. Accordingly, we treat each purchase order as a discrete exercise of the customer&amp;#8217;s option (i.e. a separate contract) rather than as a component of the overall arrangement. The pricing for the manufacturing and supply is generally at a fixed price and may be subject to annual producer price index (PPI) adjustments. We invoice and recognize product sales when title and risk of loss pass to the customer, which generally occurs upon shipment. Customer payments are generally due 30 days from receipt of invoice. We test our products for adherence to technical specifications before shipment; accordingly, we have not experienced any significant returns from our customers.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;Royalty Revenue&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Generally, we are entitled to royalties from our collaboration partners based on the net sales of their approved drugs that are marketed and sold in one or more countries where we hold royalty rights. For arrangements that include sales-based royalties, including commercial milestone payments based on the level of sales, we have concluded that the license is the predominant item to which the royalties relate. Accordingly, we recognize royalty revenue, including for our non-cash royalties, when the underlying sales occur based on our best estimates of sales of the drugs. Our partners generally pay royalties or commercial milestones after the end of the calendar quarter in accordance with contractual terms. We present commercial milestone payments within license, collaboration and other revenue.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;License, Collaboration and other Revenue&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;License Grants&lt;font style="font-style:normal;"&gt;:&amp;#160;For collaboration arrangements that include a grant of a license to our intellectual property, we consider whether the license grant is distinct from the other performance obligations included in the arrangement. Generally, we would conclude that the license is distinct if the customer is able to benefit from the license with the resources available to it. For licenses that are distinct, we recognize revenues from nonrefundable, upfront payments and other consideration allocated to the license when the license term has begun and we have provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;Milestone Payments&lt;font style="font-style:normal;"&gt;:&amp;#160;At the inception of the arrangement and at each reporting date thereafter, we assess whether we should include any milestone payments or other forms of variable consideration in the transaction price, based on whether a significant reversal of revenue previously recognized is not probable upon resolution of the uncertainty. Since milestone payments may become payable to us upon the initiation of a clinical study or filing for or receipt of regulatory approval, we review the relevant facts and circumstances to determine when we should update the transaction price, which may occur before the triggering event. When we do update the transaction price for milestone payments, we allocate it on a relative standalone selling price basis and record revenue on a cumulative catch-up basis, which results in recognizing revenue for previously satisfied performance obligations in such period. Our partners generally pay development milestones subsequent to achievement of the triggering event.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;Research and Development Services&lt;font style="font-style:normal;"&gt;: For amounts allocated to our research and development obligations in a collaboration arrangement, we recognize revenue over time using a proportional performance model, representing the transfer of goods or services as we perform activities over the term of the agreement. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Research and Development Expense&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Research and development costs are expensed as incurred and include salaries, benefits and other operating costs such as outside services, supplies and allocated overhead costs. We perform research and development for our proprietary drug candidates and technology development and for certain third parties under collaboration agreements. For our proprietary drug candidates and our internal technology development programs, we invest our own funds without reimbursement from a third party. Where we perform research and development activities under a clinical joint development collaboration, such as our collaboration with Bristol-Myers Squibb Company (BMS), we record the cost reimbursement from our partner as a reduction to research and development expense when reimbursement amounts are due to us under the agreement. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We record an accrued expense for the estimated costs of our clinical trial activities performed by third parties. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of certain clinical trial activities. We generally accrue costs associated with the start-up and reporting phases of the clinical trials ratably over the estimated duration of the start-up and reporting phases. We generally accrue costs associated with the treatment phase of clinical trials based on the total estimated cost of the treatment phase on a per patient basis and we expense the per patient cost ratably over the estimated patient treatment period based on patient enrollment in the trials. In specific circumstances, such as for certain time-based costs, we recognize clinical trial expenses using a methodology that we consider to be more reflective of the timing of costs incurred. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We record an accrued expense for the estimated costs of our contract manufacturing activities performed by third parties. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts include upfront payments and milestone payments, which depend on factors such as the achievement of the completion of certain stages of the manufacturing process. For purposes of recognizing expense, we assess whether we consider the production process is sufficiently defined to be considered the delivery of a good, as evidenced by predictive or contractually required yields in the production process, or the delivery of a service, where processes and yields are developing and less certain. If we consider the process to be the delivery of a good, we recognize expense when the drug product is delivered, or we otherwise bear risk of loss. If we consider the process to be the delivery of a service, we recognize expense based on our best estimates of the contract manufacturer&amp;#8217;s progress towards completion of the stages in the contracts. We recognize and amortize upfront payments and accrue liabilities based on the specific terms of each arrangement. Certain arrangements may provide upfront payments for certain stages of the arrangement and milestone payments for the completion of certain stages, and, accordingly, we may record advance payments for services that have not been completed or goods not delivered and liabilities for stages where the contract manufacturer is entitled to a milestone payment.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Advance payments for goods or services that will be used or rendered for future research and development activities are capitalized as prepaid expenses and recognized as expense as the related goods are delivered or the related services are performed. We base our estimates on the best information available at the time. However, additional information may become available to us which may allow us to make a more accurate estimate in future periods. In this event, we may be required to record adjustments to research and development expenses in future periods when the actual level of activity becomes more certain. Such increases or decreases in cost are generally considered to be changes in estimates and will be reflected in research and development expenses in the period identified.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Long-Lived Assets&lt;/p&gt;

In the case of property, plant and equipment and right-of-use assets, we determine whether there has been an impairment by comparing the carrying value of the asset to the anticipated undiscounted net cash flows associated with the asset. If such cash flows are less than the carrying value, we write down the asset to its fair value, which may be measured as anticipated discounted net cash flows associated with the asset. In the case of goodwill impairment, we compare the carrying value of the reporting unit to its fair value, which we generally measure using market capitalization for our single reporting unit. If an impairment exists, we write down goodwill such that the carrying value of the reporting units equals its fair value. &lt;/p&gt;

Due to our unrealized gain on available-for-sale securities in the three months ended March 31, 2019, we recorded a tax provision against such gain with an offsetting tax benefit in continuing operations of $1.1 million. The U.S. federal deferred tax assets generated from our net operating losses have been fully reserved, as we believe it is not more likely than not that the benefit will be realized.&lt;/p&gt;

The guidance clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under ASC 606 when the collaborative arrangement participant is a customer for a promised good or service that is distinct within the collaborative arrangement. The guidance also precludes entities from presenting amounts related to transactions with a collaborative arrangement participant that is not a customer as revenue, unless those transactions are directly related to third-party sales. ASU 2018-18 is effective in the first quarter of 2020 and should be applied retrospectively to January 1, 2018, when we adopted ASC 606. Early adoption is permitted. We are evaluating the effect of adoption, but we do not expect a material effect on our revenue.&lt;/p&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureAndSignificantAccountingPoliciesTextBlock>

Our investments in debt securities are subject to interest rate risk.

As of March 31, 2019 and December 31, 2018, all of our long-term investments had maturities between one and two years. &lt;/p&gt;

During the three months ended March 31, 2018, we sold available-for-sale securities totaling&amp;#160;$12.0 million, and during the three months ended March 31, 2019, we sold no available-for-sale securities. Gross realized gains and losses on those 2018 sales were not significant.&amp;#160;The cost of securities sold is based on the specific identification method.&lt;/p&gt;

Inventory is valued at the lower of cost or net realizable value and defective or excess inventory is written down to net realizable value based on historical experience or projected usage.

Prior period amounts have not been adjusted and continue to be reported in accordance with our historic accounting under ASC 840.&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We determine if an arrangement contains a lease at the inception of the arrangement. We include operating leases in operating lease right-of-use assets, operating lease liabilities, current portion, and operating lease liabilities, less current portion in our Condensed Consolidated Balance Sheets as of March 31, 2019. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We recognize operating lease right-of-use assets and liabilities at the lease commencement date based on the present value of lease payments over the expected lease term. In determining the present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date. However, in determining the present value of our lease payments for leases in effect when we adopted ASC 842, we used our incremental borrowing rate as of January 1, 2019. We have elected to recognize lease incentives, such as tenant improvement allowances, at the lease commencement date as a reduction of the right-of-use asset and lease liability to the extent that the lease provides a specified fixed or maximum level of reimbursement and we are reasonably certain to incur reimbursable costs at least equaling such amounts. For leases in effect as of January 1, 2019, we recognized our lease incentives as part of our transition adjustment. Our expected lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise any such options. We recognize lease expense on a straight-line basis over the expected lease term. &lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;For our facilities leases, we have elected a practical expedient provided by ASC 842 to account for the lease and non-lease components, such as common area maintenance charges, as a single lease component. &lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In August 2017, we entered into a Lease Agreement (the Mission Bay Lease) with ARE-San Francisco No. 19, LLC (ARE) and terminated our sublease with Pfizer, Inc., effectively extending our lease term from 2020 to 2030 for our 137,046 square foot corporate office and R&amp;amp;D facility located at 455 Mission Bay Boulevard, San Francisco, California (the Mission Bay Facility). The term of the Mission Bay Lease commenced on September 1, 2017, and will expire January 31, 2030, subject to our right to extend the term of the lease for two consecutive five-year periods, which we have excluded from our determination of the lease term. The monthly base rent for the Mission Bay Facility will escalate over the term of the lease at various intervals. During the term of the Mission Bay Lease, we are responsible for paying our share of operating expenses specified in the lease, including utilities, common area maintenance, insurance and taxes. The Mission Bay Lease also obligates us to rent from ARE a total of an additional approximately 15,000 square feet of space at the Mission Bay Facility. During the three months ended March 31, 2019, ARE delivered 2,690 square feet of space, and therefore we recognized a right-of-use asset and lease liability of $1.3 million for this space. The Mission Bay Lease includes various covenants, indemnities, defaults, termination rights, security deposits and other provisions customary for lease transactions of this nature.&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:5.06%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In May 2018, we entered into a Lease Agreement (the Third Street Lease) with Kilroy Realty Finance Partnership, L.P. to lease 135,936 square feet of space located at 360 Third Street, San Francisco, California (the Third Street Facility) from June 2018 to January 31, 2030, subject to our right to extend the term for a consecutive five-year period, which we have excluded from our determination of the lease term. An initial 1,726 square feet was delivered in June 2018, and a total of 67,105 square feet for two additional spaces was delivered in December 2018. The remaining space will be delivered in phases during 2019. The Third Street Lease will provide us additional facilities to support increased personnel for our San Francisco-based R&amp;amp;D activities. Our fixed monthly base rent on an industrial gross lease basis includes certain expenses and property taxes paid directly by the landlord and will escalate each year over the term at specified intervals. We have a onetime right of first offer with respect to certain additional rental space at the Third Street Facility. The Third Street Lease includes various covenants, indemnities, defaults, termination rights, security deposits and other provisions customary for lease transactions of this nature. &lt;/p&gt;

Hoffmann-La&amp;#160;Roche Ltd and Hoffmann-La&amp;#160;Roche Inc. (together referred to as Roche). We received aggregate cash proceeds of $124.0 million for the Royalty Entitlement.&amp;#160;As part of this sale, we incurred approximately $4.4 million in transaction costs, which will be amortized to interest expense over the estimated life of the Purchase and Sale Agreement. Although we sold all of our rights to receive royalties from the CIMZIA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174; &lt;/sup&gt;and MIRCERA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; products, as a result of our ongoing manufacturing and supply obligations related to the generation of these royalties, we will continue to account for these royalties as revenue. We recorded the $124.0 million in proceeds from this transaction as a liability (Royalty Obligation) that will be amortized using the interest method over the estimated life of the Purchase and Sale Agreement as royalties from the CIMZIA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; and MIRCERA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; products are remitted directly to RPI. During the three months ended March 31, 2019 and 2018, we recognized $8.2 million and $6.9 million, respectively, in non-cash royalty revenue from net sales of CIMZIA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; and MIRCERA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;, and we recorded $6.1 million and $5.0 million, respectively, of related non-cash interest expense.&lt;/p&gt;

From inception through 2017, our estimate of the total interest expense on the Royalty Obligation resulted in an effective annual interest rate of approximately 17%. &lt;font style="color:#000000;"&gt;During the three months ended December 31, 2017, our estimate of the effective annual interest rate over the life of the agreement increased to 17.6%, which resulted in a prospective interest rate of &lt;/font&gt;approximately 21%.&amp;nbsp;&amp;nbsp;During the three months ended December 31, 2018, primarily as a result of increases in the forecasted sales of MIRCERA&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;, our estimate of the effective annual interest rate over the life of the agreement increased to 18.7%, which results in a prospective interest rate of 29%. &lt;/p&gt;

To our knowledge, we are currently in compliance with these provisions of the Purchase and Sale Agreement; however, if we were to breach our obligations, we could be required to pay damages to RPI that are not limited to the purchase price we received in the sale transaction.&lt;/p&gt;</nktr:LiabilityRelatedToSaleOfPotentialFutureRoyaltiesTextBlock>

We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. If any unfavorable ruling were to occur in any specific period, there exists the possibility of a material adverse impact on the results of our operations of that period and on our cash flows and liquidity. &lt;/p&gt;

Nektar Therapeutics et. al., N.D. Cal.&amp;nbsp;&amp;nbsp;Also, on February 13, 2019, and February 18, 2019, shareholder derivative complaints were filed in the U.S. District Court for the District of Delaware naming the CEO, CFO and certain members of Nektar&amp;#8217;s board. Both the class action and shareholder derivative actions assert, among other things, that for a period beginning at least from November 11, 2017 through October 2, 2018, our stock was inflated due to alleged misrepresentations about the efficacy and safety of NKTR-214. These cases are in the early stages. Accordingly, we cannot reasonably estimate any range of potential future charges, and we have not recorded any accrual for a contingent liability associated with these legal proceedings. However, an unfavorable resolution could potentially have a material adverse effect on our business, financial condition, and results of operations or prospects, and potentially result in paying monetary damages.&amp;nbsp;&amp;nbsp;&lt;/p&gt;

The term of these indemnification obligations is generally perpetual any time after execution of the agreement. There is generally no limitation on the potential amount of future payments we could be required to make under these indemnification obligations.&lt;/p&gt;

In the event it is determined that we breached certain of the representations and warranties or covenants made by us in any such agreements, we could incur substantial indemnification liabilities depending on the timing, nature, and amount of any such claims.&lt;/p&gt;

&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:4.54%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;On February 13, 2018, we entered into a Strategic Collaboration Agreement (BMS Collaboration Agreement) and a Share Purchase Agreement with BMS, both of which became effective on April 3, 2018. Pursuant to these agreements, we and BMS will jointly develop NKTR-214, including, without limitation, in combination with BMS&amp;#8217;s Opdivo&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; (nivolumab) and Opdivo&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; plus Yervoy&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; (ipilimumab), and other compounds of BMS, us or any third party. The parties have agreed to jointly commercialize NKTR-214 on a worldwide basis. We retained the right to record all worldwide sales for NKTR-214. We will share global commercialization profits and losses with BMS for NKTR-214, with Nektar sharing 65% and BMS sharing 35% of the net profits and losses. The parties will share the internal and external development costs for NKTR-214 in combination regimens based on each party&amp;#8217;s relative ownership interest in the compounds included in the regimens.&lt;font style="Background-color:#FFFFFF;color:#000000;"&gt; In accordance with the agreement, the parties will share development costs for&amp;#160;NKTR-214&amp;#160;in combination with&amp;#160;Opdivo&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;font-size:8.5pt;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;"&gt;, 67.5% of costs to BMS and 32.5% to Nektar, and for&amp;#160;NKTR-214&amp;#160;in a triplet combination with&amp;#160;Opdivo&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;font-size:8.5pt;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;"&gt;&amp;#160;and&amp;#160;Yervoy&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;font-size:8.5pt;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;font style="Background-color:#FFFFFF;color:#000000;"&gt;, 78% of costs to BMS and 22% to Nektar.&amp;#160;The parties will share costs for the production of NKTR-214, 35% of costs to BMS and 65% to Nektar.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:4.54%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The BMS Collaboration Agreement superseded and replaced the Clinical Trial Agreement we entered into with BMS in September 2016 to develop NKTR-214 in combination with Opdivo&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;. Under the Clinical Trial Agreement, we acted as the sponsor of each Combination Therapy Trial and BMS was responsible for 50% of all out-of-pocket costs reasonably incurred in connection with third party contract research organizations, laboratories, clinical sites and institutional review boards. We recorded cost reimbursement payments to us from BMS as a reduction to research and development expense. Each party was otherwise responsible for its own internal costs, including internal personnel costs, incurred in connection with each Combination Therapy Trial.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:5.06%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Upon the effective date of the BMS Collaboration Agreement in April 2018, BMS paid us a non-refundable upfront cash payment of $1.0 billion. We are eligible to receive additional cash payments up to a total of approximately $1.4 billion upon the achievement of certain development and regulatory milestones and up to a total of $350.0 million upon the achievement of certain sales milestones. In April 2018, BMS also purchased 8,284,600 shares of our common stock pursuant to the Share Purchase Agreement for total additional cash consideration of $850.0 million. &lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:5%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We determined that the BMS Collaboration Agreement falls within the scope of ASC 808. As mentioned above, BMS shares certain percentages of development costs incurred by us and we share certain percentages of development costs incurred by BMS. We consider these activities to represent collaborative activities under ASC 808 and we recognize such cost sharing proportionately with the performance of the underlying services. We recognize BMS&amp;#8217; reimbursement of our costs as a reduction of research and development expense and our reimbursement of BMS&amp;#8217; costs as research and development expense. During the three months ended March 31, 2019 and 2018, we recorded $28.8 million and $2.3 million, respectively, as a reduction of research and development expenses for BMS&amp;#8217; share of our expenses, net of our share of BMS&amp;#8217; expenses.&amp;#160;As of March 31, 2019, we have recorded a receivable of $28.4 million from BMS in accounts receivable in our Condensed Consolidated Balance Sheet.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:4.54%;color:#000000;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We analogized to ASC 606 for the accounting for our two performance obligations, consisting of the delivery of the licenses to develop and commercialize NKTR-214 and our participation on joint steering and other collaboration committees. We determined that our committee participation is not material.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:4.54%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We aggregated the total consideration of $1.85 billion received under the agreements and allocated it between the stock purchase and the revenue-generating elements, because we and BMS negotiated the agreements together and the effective date of the BMS Collaboration Agreement was dependent upon the effective date of the Share Purchase Agreement. We recorded the estimated fair value of the shares of $790.2 million in stockholders&amp;#8217; equity based on the closing date price of our common stock of $99.36, adjusted for a discount for lack of marketability reflecting the unregistered nature of the shares. We allocated the remaining $1,059.8 million to the transaction price of the collaboration agreement. We consider the future potential development, regulatory and sales milestones of up to approximately $1.8 billion to be variable consideration. We excluded these milestones from the transaction price as of March 31, 2019 due to the significant uncertainties involved with clinical development and regulatory approval. We will re-evaluate the transaction price at each reporting period and as uncertain events are resolved or other changes in circumstances occur.&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:5%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Accordingly, we allocated the entire transaction price of $1,059.8 million to the granting of the licenses and therefore recognized $1,059.8 million for the year ended December 31, 2018 as license, collaboration and other revenue.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;color:#000000;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Eli Lilly and Company&lt;font style="color:#000000;"&gt; (Lilly&lt;/font&gt;&lt;font style="font-weight:normal;color:#000000;"&gt;): NKTR-358&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Effective August 23, 2017, we entered into a worldwide license agreement with Eli Lilly and Company (Lilly) to co-develop NKTR-358, a novel immunological drug candidate that we invented.&lt;font style="font-size:11pt;"&gt; &lt;/font&gt;Under the terms of the agreement, we (i) received an initial payment of $150.0 million in September 2017 and are eligible for up to $250.0 million in additional development milestones, (ii) will co-develop NKTR-358 with Lilly, for which we are responsible for completing Phase 1 clinical development and certain drug product development and supply activities, (iii) will share with Lilly Phase 2 development costs with 75% of those costs borne by Lilly and 25% of the costs borne by us, (iv) will have the option to contribute funding to Phase 3 development on an indication-by-indication basis ranging from zero to 25% of development costs, and (v) will have the opportunity to receive up to double-digit sales royalty rates that escalate based upon our Phase 3 development cost contribution and the level of annual global product sales. Lilly will be responsible for all costs of global commercialization and we will have an option to co-promote in the U.S. under certain conditions. A portion of the development milestones may be reduced by 50% under certain conditions, related to the final formulation of the approved product and the timing of prior approval (if any) of competitive products with a similar mechanism of action, which could reduce these milestone payments by 75% if both conditions occur.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The agreement will continue until Lilly no longer has any royalty payment obligations or, if earlier, the termination of the agreement in accordance with its terms. The agreement may be terminated by Lilly for convenience, and may also be terminated under certain other circumstances, including material breach.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We identified our license grant to Lilly, our ongoing Phase 1 clinical development obligation and our drug product development obligation as the significant performance obligations in the arrangement. The valuation of each performance obligation involves significant estimates and assumptions, including but not limited to, expected market opportunity and pricing, assumed royalty rates, clinical trial costs, timelines and likelihood of success; in each case these estimates and assumptions covering long time periods. We determined the selling price for the license based on a discounted cash flow analysis of projected revenues from NKTR-358 and development and commercial costs using a discount rate based on a market participant&amp;#8217;s weighted average cost of capital adjusted for forecasting risk. We determined the selling prices for our Phase 1 clinical development and drug product development deliverables based on the nature of the services to be performed and estimates of the associated efforts and third-party rates for similar services. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Although we are entitled to significant development milestones under this arrangement, as of March 31, 2019, we have excluded such milestones from the transaction price due to the significant uncertainties involved with clinical development. We have therefore determined the transaction price to consist of the upfront payment of $150.0 million in September 2017. Based on our estimates of the standalone selling prices of the performance obligations, we allocated the $150.0 million upfront payment as $125.9 million to the license, $17.6 million to the Phase 1 clinical development and $6.5 million to the drug product development. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We recognized the $125.9 million of revenue allocated to the license upon the effective date of the license agreement in August 2017, since we determined that the license was a right to use our intellectual property, for which, as of the effective date, we had provided all necessary information to Lilly to benefit from the license and the license term had begun. We recognize revenue for the Phase 1 clinical development and drug product development using an input method, using costs incurred, as this method depicts our progress towards providing Lilly with the results of clinical trials and drug production processes. As of March 31, 2019, we have deferred revenue of approximately $5.8 million related to this agreement, which we expect to recognize through December 2019, the estimated end of our performance obligations under this agreement. &lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Baxalta Incorporated/Takeda&lt;font style="font-weight:normal;"&gt;: Hemophilia&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We are a party to an exclusive research, development, license and manufacturing and supply agreement with Baxalta Incorporated (Baxalta), a subsidiary of Takeda Pharmaceutical Company Ltd. (Takeda), entered into in September 2005 to develop products designed to improve therapies for Hemophilia A patients using our PEGylation technology. Under the terms of the agreement, we are entitled to research and development funding for our active programs, which are now complete for Factor VIII, and are responsible for supplying Takeda with its requirements for our proprietary materials. Takeda is responsible for all clinical development, regulatory, and commercialization expenses. The agreement is terminable by the parties under customary conditions.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;This Hemophilia A program includes ADYNOVATE&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;, which was approved by the United States Food and Drug Administration (FDA) in November 2015 for use in adults and adolescents, aged 12 years and older, who have Hemophilia A, and is now marketed in the U.S., the European Union, and many other countries. As a result of the marketing authorization in the EU in January 2018, we earned a $10.0 million development milestone, which was received in March 2018. We updated the transaction price for this milestone in January 2018 since we had previously excluded it due to the significant uncertainty from regulatory approval. Based on the terms of this milestone, we allocated the entire milestone to the license grant and research and development services, and therefore recognized the entire $10.0 million in the three months ended March 31, 2018 as we had previously satisfied those performance obligations. &lt;font style="color:#000000;"&gt;In December 2018, we earned an additional $10.0 million milestone for annual sales of ADYNOVATE&lt;/font&gt;&lt;font style="color:#000000;font-size:8.5pt;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;font style="color:#000000;"&gt;/ADYNOVI&lt;/font&gt;&lt;font style="color:#000000;font-size:8.5pt;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;TM&lt;/sup&gt;&lt;/font&gt;&lt;font style="color:#000000;"&gt; reaching a certain specified amount.&amp;#160;&lt;/font&gt;In addition, we are entitled to an additional sales milestone upon achievement of an annual sales target and royalties based on annual worldwide net sales of products resulting from this agreement. &lt;/p&gt;
&lt;p style="text-align:justify;Background-color:#FFFFFF;margin-bottom:0pt;margin-top:12pt;text-indent:4.54%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In October 2017, we entered into a right to sublicense agreement with Baxalta, under which we granted to Baxalta the right to grant a nonexclusive sublicense to certain patents that were previously exclusively licensed to Baxalta under our 2005 agreement. Under the right to sublicense agreement, Baxalta paid us $12.0 million in November 2017 and agreed to pay us single digit royalty payments based upon net sales of the products covered under the sublicense throughout the term of the agreement. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Our remaining unsatisfied performance obligation consists of our ongoing supply of PEGylation materials at a price less than the standalone selling price of these materials. As of March 31, 2019, our deferred revenue from this arrangement is not significant.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;Amgen, Inc&lt;font style="font-weight:normal;"&gt;.: Neulasta&lt;/font&gt;&lt;font style="font-weight:normal;font-style:normal;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In October 2010, we amended and restated an existing supply and license agreement by entering into a supply, dedicated suite and manufacturing guarantee agreement (the Amended and Restated Agreement) and a license agreement with Amgen Inc. and Amgen Manufacturing, Limited (together referred to as Amgen). Under the terms of the Amended and Restated Agreement, we received a $50.0 million payment in the fourth quarter of 2010 in return for our guaranteeing the supply of certain quantities of our proprietary PEGylation materials to Amgen. &lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;We determined that our obligation to manufacture and supply our PEGylation materials and to maintain the dedicated manufacturing suite solely for the production of such materials for Amgen represented an obligation to stand ready to manufacture such materials. We concluded that we should recognize revenue based on the passage of time as this method depicts the satisfaction of Amgen&amp;#8217;s right to require production of PEGylation materials at any time. As of March 31, 2019, we have deferred revenue of approximately $7.9 million related to this agreement, which we expect to recognize through October 2020, the estimated end of our obligations under this agreement.&lt;/p&gt;
&lt;p style="margin-top:18pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-style:italic;font-family:Times New Roman;font-size:10pt;text-transform:none;font-variant: normal;"&gt;AstraZeneca AB&lt;font style="font-weight:normal;"&gt;: MOVANTIK&lt;/font&gt;&lt;font style="font-weight:normal;font-style:normal;"&gt;&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;&lt;/font&gt;&lt;font style="font-weight:normal;"&gt; (naloxegol oxalate), previously referred to as naloxegol and NKTR-118&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:6pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In September 2009, we entered into an agreement with AstraZeneca AB (AstraZeneca) under which we granted AstraZeneca a worldwide, exclusive license under our patents and other intellectual property to develop, market, and sell MOVANTIK&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;. AstraZeneca is responsible for all research, development and commercialization and is responsible for all drug development and commercialization decisions for MOVANTIK&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;. In September 2014 and December 2014, MOVANTIK&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174; &lt;/sup&gt;/MOVENTIG&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174; &lt;/sup&gt;was approved in the US and EU, respectively. As of March 31, 2019, we have received a total of $385.0 million of upfront and contingent milestone payments from this agreement, all of which was received in or before 2015. In addition, we are entitled to significant and escalating double-digit royalty payments and sales milestone payments based on annual worldwide net sales of MOVANTIK&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt;.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In March 2016, AstraZeneca announced that it had entered into an agreement with ProStrakan Group plc, a subsidiary of Kyowa Hakko Kirin Co. Ltd. (Kirin), granting Kirin exclusive marketing rights to MOVENTIG&lt;sup style="font-size:85%; vertical-align:top"&gt;&amp;#174;&lt;/sup&gt; in the EU, Iceland, Liechtenstein, Norway and Switzerland. Under our license agreement with AstraZeneca, we and AstraZeneca will share the upfront payment, market access milestone payments, royalties and sales milestone payments made by Kirin to AstraZeneca with AstraZeneca receiving 60% and Nektar receiving 40%. As of March 31, 2019, we do not have deferred revenue related to our agreement with AstraZeneca.&lt;/p&gt;

However, given the current phase of development of the potential products under these collaboration agreements, we cannot estimate the probability or timing of achieving these milestones and, therefore, have excluded all development milestones from the respective transaction prices for these agreements. As of March 31, 2019, we have deferred revenue of approximately $6.0 million related to these other collaboration agreements.&lt;/p&gt;</us-gaap:CollaborativeArrangementDisclosureTextBlock>

We may also perform research, development, manufacturing and supply activities under our collaboration agreements. Consideration under these contracts may include an upfront payment, development milestones and other contingent payments, expense reimbursements, royalties based on net sales of approved drugs, and commercial sales milestone payments. Additionally, these contracts may provide options for the customer to purchase our proprietary PEGylation materials, drug candidates or additional contract research and development services under separate contracts. &lt;/p&gt;

However, if we conclude that our collaboration partner is not a customer for certain activities and associated payments, such as for certain collaborative research, development, manufacturing and commercial activities, we present such payments as a reduction of research and development expense or general and administrative expense, based on where we present the underlying expense. &lt;/p&gt;</us-gaap:CollaborativeArrangementAccountingPolicy>

For arrangements that include multiple performance obligations, such as granting a license or performing contract research and development activities or participation on joint steering or other committees, we allocate upfront and milestone payments under a relative standalone selling price method. Accordingly, we develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. These key assumptions may include revenue forecasts, clinical development timelines and costs, discount rates and probabilities of clinical and regulatory success.&lt;/p&gt;

We have assessed our current manufacturing and supply arrangements and have generally determined that they provide the customer an option to purchase our proprietary PEGylation materials. Accordingly, we treat each purchase order as a discrete exercise of the customer&amp;#8217;s option (i.e. a separate contract) rather than as a component of the overall arrangement. The pricing for the manufacturing and supply is generally at a fixed price and may be subject to annual producer price index (PPI) adjustments. We invoice and recognize product sales when title and risk of loss pass to the customer, which generally occurs upon shipment. Customer payments are generally due 30 days from receipt of invoice. We test our products for adherence to technical specifications before shipment; accordingly, we have not experienced any significant returns from our customers.&lt;/p&gt;

For arrangements that include sales-based royalties, including commercial milestone payments based on the level of sales, we have concluded that the license is the predominant item to which the royalties relate. Accordingly, we recognize royalty revenue, including for our non-cash royalties, when the underlying sales occur based on our best estimates of sales of the drugs. Our partners generally pay royalties or commercial milestones after the end of the calendar quarter in accordance with contractual terms. We present commercial milestone payments within license, collaboration and other revenue.&lt;/p&gt;

Generally, we would conclude that the license is distinct if the customer is able to benefit from the license with the resources available to it. For licenses that are distinct, we recognize revenues from nonrefundable, upfront payments and other consideration allocated to the license when the license term has begun and we have provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-style:italic;font-family:Times New Roman;font-size:10pt;font-weight:normal;text-transform:none;font-variant: normal;"&gt;Milestone Payments&lt;font style="font-style:normal;"&gt;:&amp;#160;At the inception of the arrangement and at each reporting date thereafter, we assess whether we should include any milestone payments or other forms of variable consideration in the transaction price, based on whether a significant reversal of revenue previously recognized is not probable upon resolution of the uncertainty. Since milestone payments may become payable to us upon the initiation of a clinical study or filing for or receipt of regulatory approval, we review the relevant facts and circumstances to determine when we should update the transaction price, which may occur before the triggering event. When we do update the transaction price for milestone payments, we allocate it on a relative standalone selling price basis and record revenue on a cumulative catch-up basis, which results in recognizing revenue for previously satisfied performance obligations in such period. Our partners generally pay development milestones subsequent to achievement of the triggering event.&lt;/font&gt;&lt;/p&gt;

We perform research and development for our proprietary drug candidates and technology development and for certain third parties under collaboration agreements. For our proprietary drug candidates and our internal technology development programs, we invest our own funds without reimbursement from a third party. Where we perform research and development activities under a clinical joint development collaboration, such as our collaboration with Bristol-Myers Squibb Company (BMS), we record the cost reimbursement from our partner as a reduction to research and development expense when reimbursement amounts are due to us under the agreement. &lt;/p&gt;

The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of certain clinical trial activities. We generally accrue costs associated with the start-up and reporting phases of the clinical trials ratably over the estimated duration of the start-up and reporting phases. We generally accrue costs associated with the treatment phase of clinical trials based on the total estimated cost of the treatment phase on a per patient basis and we expense the per patient cost ratably over the estimated patient treatment period based on patient enrollment in the trials. In specific circumstances, such as for certain time-based costs, we recognize clinical trial expenses using a methodology that we consider to be more reflective of the timing of costs incurred. &lt;/p&gt;

The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts include upfront payments and milestone payments, which depend on factors such as the achievement of the completion of certain stages of the manufacturing process. For purposes of recognizing expense, we assess whether we consider the production process is sufficiently defined to be considered the delivery of a good, as evidenced by predictive or contractually required yields in the production process, or the delivery of a service, where processes and yields are developing and less certain. If we consider the process to be the delivery of a good, we recognize expense when the drug product is delivered, or we otherwise bear risk of loss. If we consider the process to be the delivery of a service, we recognize expense based on our best estimates of the contract manufacturer&amp;#8217;s progress towards completion of the stages in the contracts. We recognize and amortize upfront payments and accrue liabilities based on the specific terms of each arrangement. Certain arrangements may provide upfront payments for certain stages of the arrangement and milestone payments for the completion of certain stages, and, accordingly, we may record advance payments for services that have not been completed or goods not delivered and liabilities for stages where the contract manufacturer is entitled to a milestone payment.&lt;/p&gt;

We base our estimates on the best information available at the time. However, additional information may become available to us which may allow us to make a more accurate estimate in future periods. In this event, we may be required to record adjustments to research and development expenses in future periods when the actual level of activity becomes more certain. Such increases or decreases in cost are generally considered to be changes in estimates and will be reflected in research and development expenses in the period identified.&lt;/p&gt;</us-gaap:ResearchAndDevelopmentExpensePolicy>

In the case of property, plant and equipment and right-of-use assets, we determine whether there has been an impairment by comparing the carrying value of the asset to the anticipated undiscounted net cash flows associated with the asset. If such cash flows are less than the carrying value, we write down the asset to its fair value, which may be measured as anticipated discounted net cash flows associated with the asset. In the case of goodwill impairment, we compare the carrying value of the reporting unit to its fair value, which we generally measure using market capitalization for our single reporting unit. If an impairment exists, we write down goodwill such that the carrying value of the reporting units equals its fair value. &lt;/p&gt;</us-gaap:PropertyPlantAndEquipmentPolicyTextBlock>

The guidance clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under ASC 606 when the collaborative arrangement participant is a customer for a promised good or service that is distinct within the collaborative arrangement. The guidance also precludes entities from presenting amounts related to transactions with a collaborative arrangement participant that is not a customer as revenue, unless those transactions are directly related to third-party sales. ASU 2018-18 is effective in the first quarter of 2020 and should be applied retrospectively to January 1, 2018, when we adopted ASC 606. Early adoption is permitted. We are evaluating the effect of adoption, but we do not expect a material effect on our revenue.&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>
