Organization and Business
Organization and Business
1.     Organization and Business
          Halozyme Therapeutics, Inc. (“Halozyme” or the “Company”) is a biopharmaceutical company dedicated to the development and commercialization of recombinant human enzymes that either transiently modify tissue under the skin to facilitate injection of other therapies or correct diseased tissue structures for clinical benefit. The Company’s existing products and its products under development are based primarily on intellectual property covering the family of human enzymes known as hyaluronidases.
          The Company’s operations to date have involved: (i) organizing and staffing its operating subsidiary, Halozyme, Inc.; (ii) acquiring, developing and securing its technology; (iii) undertaking product development for its existing products and a limited number of product candidates; and (iv) supporting the development of partnered product candidates. The Company currently has multiple proprietary programs in various stages of research and development. In addition, the Company has collaborative partnerships with F. Hoffmann-La Roche, Ltd and Hoffmann-La Roche, Inc. (“Roche”), Baxter Healthcare Corporation (“Baxter”), ViroPharma Incorporated (“ViroPharma”) and Intrexon Corporation (“Intrexon”) to apply the Company’s proprietary EnhanzeÔ Technology to the partners’ biological therapeutic compounds. The Company also had a partnership with Baxter, under which Baxter had worldwide marketing rights for HYLENEX®, a registered trademark of Baxter International, Inc. (the “HYLENEX Partnership”). In January 2011, the Company and Baxter mutually agreed to terminate the HYLENEX Partnership. There are two marketed products that utilize the Company’s technology: HYLENEX, a hyaluronidase human injection used as an adjuvant to enhance the dispersion and absorption of other injected drugs and fluids, and ICSI Cumulase®, a product used for in vitro fertilization (“IVF”). Currently, the Company has received only limited revenue from the sales of active pharmaceutical ingredients (“API”) to the third party that produces ICSI Cumulase, in addition to other revenues from its collaborative partnerships.
Summary of Significant Accounting Policies
Summary of Significant Accounting Policies
2.     Summary of Significant Accounting Policies
Basis of Presentation
          The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) related to a quarterly report on Form 10-Q. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for a complete set of financial statements. These interim unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, filed with the SEC on March 11, 2011. The unaudited financial information for the interim periods presented herein reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial condition and results of operations for the periods presented, with such adjustments consisting only of normal recurring adjustments. Operating results for interim periods are not necessarily indicative of the operating results for an entire fiscal year.
          The consolidated financial statements include the accounts of Halozyme Therapeutics, Inc. and its wholly owned subsidiary, Halozyme, Inc. All intercompany accounts and transactions have been eliminated.
          The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates and judgments, which are based on historical and anticipated results and trends and on various other assumptions that management believes to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ from management’s estimates.
Adoption of Recent Accounting Pronouncements
          Effective January 1, 2011, the Company adopted on a prospective basis Financial Accounting Standards Board’s (“FASB”) Accounting Standards Update (“ASU”) No. 2010-17, Revenue Recognition (Topic 605): Milestone Method of Revenue Recognition (“Milestone Method”). ASU No. 2010-17 states that the Milestone Method is a valid application of the proportional performance model when applied to research or development arrangements. Accordingly, an entity can make an accounting policy election to recognize a payment that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. The Milestone Method is not required and is not the only acceptable method of revenue recognition for milestone payments. The adoption of ASU No. 2010-17 did not have a material impact on the Company’s consolidated financial position or results of operations.
          Effective January 1, 2011, the Company adopted on a prospective basis FASB’s ASU No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements. ASU No. 2009-13 requires an entity to allocate arrangement consideration at the inception of an arrangement to all of its deliverables based on their relative selling prices. ASU No. 2009-13 eliminates the use of the residual method of allocation and requires the relative-selling-price method in all circumstances in which an entity recognizes revenue for an arrangement with multiple deliverables subject to Accounting Standards Code 605-25. The Company accounted for the collaborative arrangements with ViroPharma and Intrexon under the provisions of ASU No. 2009-13, which resulted in revenue recognition patterns that are materially different from those recognized for the Company’s existing multiple-element arrangements.
Pending Adoption of Accounting Pronouncements
          In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. In ASU No. 2011-05, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU No. 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments in ASU No. 2011-05 do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The amendments in ASU No. 2011-05 are effective for fiscal years, and interim period within those years, beginning after December 15, 2011. The Company does not expect the adoption of ASU No. 2011-05 to have a material impact on its consolidated financial position or results of operations.
Revenue Recognition
          The Company generates revenues from product sales and collaborative agreements. The Company recognizes revenues in accordance with the authoritative guidance for revenue recognition. The Company recognizes revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured.
          Product Sales Revenue from the sales of API for ICSI Cumulase is recognized when the transfer of ownership occurs, which is upon shipment to the Company’s distributor. The Company is obligated to accept returns for product that does not meet product specifications. Historically, the Company has not had any product returns as a result of not meeting product specifications.
          In accordance with the HYLENEX Partnership with Baxter, the Company supplied Baxter with API for HYLENEX at its fully burdened cost plus a margin. Baxter filled and finished HYLENEX and held it for subsequent distribution, at which time the Company ensured it met product specifications and released it as available for sale. Because of the Company’s continued involvement in the development and production process of HYLENEX, the earnings process was not considered to be complete. Accordingly, the Company deferred the revenue and related product costs on the API for HYLENEX until the product was filled, finished, packaged and released. Baxter might only return the API for HYLENEX to the Company if it did not conform to the specified criteria set forth in the HYLENEX Partnership or upon termination of such agreement. In addition, the Company received product-based payments upon the sale of HYLENEX by Baxter, in accordance with the terms of the HYLENEX Partnership. Product sales revenues were recognized as the Company earned such revenues based on Baxter’s shipments of HYLENEX to its distributors when such amounts could be reasonably estimated. Effective January 7, 2011, the Company and Baxter mutually agreed to terminate the HYLENEX Partnership and the associated agreements. See Note 9, “Deferred Revenue,” for further discussion.
          Revenues under Collaborative Agreements The Company entered into license and collaboration agreements under which the collaborative partners obtained worldwide exclusive rights for the use of the Company’s proprietary recombinant human PH20 enzyme (“rHuPH20”) in the development and commercialization of the partners’ biologic compounds. The collaborative agreements contain multiple elements including nonrefundable payments at the inception of the arrangement, license fees, exclusivity fees, payments based on achievement of specific milestones designated in the collaborative agreements, reimbursements of research and development services, payments for supply of rHuPH20 API for the partner and/or royalties on sales of products resulting from collaborative agreements. The Company analyzes each element of its collaborative agreements and considers a variety of factors in determining the appropriate method of revenue recognition of each element.
          Prior to the adoption of ASU No. 2009-13 on January 1, 2011, in order for a delivered item to be accounted for separately from other deliverables in a multiple-element arrangement, the following three criteria had to be met: (i) the delivered item had standalone value to the customer, (ii) there was objective and reliable evidence of fair value of the undelivered items and (iii) if the arrangement included a general right of return relative to the delivered item, delivery or performance of the undelivered items was considered probable and substantially in the control of the vendor. For the collaborative agreements entered into prior to January 1, 2011, there was no objective and reliable evidence of fair value of the undelivered items. Thus, the delivered licenses did not meet all of the required criteria to be accounted for separately from undelivered items. Therefore, the Company recognizes revenue on nonrefundable upfront payments and license fees from these collaborative agreements over the period of significant involvement under the related agreements.
          For new collaborative agreements or material modifications of existing collaborative agreements entered into after December 31, 2010, the Company follows the provisions of ASU No. 2009-13. In order to account for the multiple-element arrangements, the Company identifies the deliverables included within the agreement and evaluates which deliverables represent units of accounting. Analyzing the arrangement to identify deliverables requires the use of judgment, and each deliverable may be an obligation to deliver services, a right or license to use an asset, or another performance obligation. The deliverables under the Company’s collaborative agreements include (i) the license to the Company’s rHuPH20 technology, (ii) at the collaborator’s request, research and development services which are reimbursed at contractually determined rates, and (iii) at the collaborator’s request, supply of rHuPH20 API which is reimbursed at the Company’s cost plus a margin. A delivered item is considered a separate unit of accounting when the delivered item has value to the collaborator on a standalone basis based on the consideration of the relevant facts and circumstances for each arrangement. Factors considered in this determination include the research capabilities of the partner and the availability of research expertise in this field in the general marketplace. In addition, if the arrangement includes a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the Company’s control.
          Arrangement consideration is allocated at the inception of the agreement to all identified units of accounting based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (“VSOE”), of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, the Company uses its best estimate of the selling price for the deliverable. The amount of allocable arrangement consideration is limited to amounts that are fixed or determinable. The consideration received is allocated among the separate units of accounting, and the applicable revenue recognition criteria are applied to each of the separate units. Changes in the allocation of the sales price between delivered and undelivered elements can impact revenue recognition but do not change the total revenue recognized under any agreement.
          Upfront license fee payments are recognized upon delivery of the license if facts and circumstances dictate that the license has standalone value from the undelivered items, which generally include research and development services and the manufacture of rHuPH20 API, the relative selling price allocation of the license is equal to or exceeds the upfront license fee, persuasive evidence of an arrangement exists, the Company’s price to the partner is fixed or determinable, and collectability is reasonably assured. Upfront license fee payments are deferred if facts and circumstances dictate that the license does not have standalone value. The determination of the length of the period over which to defer revenue is subject to judgment and estimation and can have an impact on the amount of revenue recognized in a given period.
          The terms of the Company’s collaborative agreements provide for milestone payments upon achievement of certain development and regulatory events and/or specified sales volumes of commercialized products by the collaborator. Prior to the Company’s adoption of the Milestone Method, the Company recognized milestone payments upon the achievement of specified milestones if: (1) the milestone was substantive in nature and the achievement of the milestone was not reasonably assured at the inception of the agreement, (2) the fees were nonrefundable and (3) the Company’s performance obligations after the milestone achievement would continue to be funded by the Company’s collaborator at a level comparable to the level before the milestone achievement.
          Effective January 1, 2011, the Company adopted on a prospective basis the Milestone Method. Under the Milestone Method, the Company recognizes consideration that is contingent upon the achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone is substantive in its entirety. A milestone is considered substantive when it meets all of the following criteria:
  1.  
The consideration is commensurate with either the entity’s performance to achieve the milestone or the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone,
 
  2.  
The consideration relates solely to past performance, and
 
  3.  
The consideration is reasonable relative to all of the deliverables and payment terms within the arrangement.
          A milestone is defined as an event (i) that can only be achieved based in whole or in part on either the entity’s performance or on the occurrence of a specific outcome resulting from the entity’s performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into that the event will be achieved and (iii) that would result in additional payments being due to the Company.
          Reimbursements of research and development services are recognized as revenue during the period in which the services are performed as long as there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the related receivable is probable. Revenue from the manufacture of rHuPH20 API is recognized when the API has met all specifications required for the collaborator acceptance and title and risk of loss have transferred to the collaborator. The Company does not directly control when any collaborator will request research and development services or supply of rHuPH20 API; therefore, the Company cannot predict when it will recognize revenues in connection with research and development services and supply of rHuPH20 API. Royalties to be received based on sales of licensed products by the Company’s collaborators incorporating the Company’s rHuPH20 API will be recognized as earned.
          The collaborative agreements typically provide the partners the right to terminate such agreement in whole or on a product-by-product or target-by-target basis at any time upon 90 days prior written notice to the Company. There are no performance, cancellation, termination or refund provisions in any of the Company’s collaborative agreements that contain material financial consequences to the Company.
          See Note 5, “Collaborative Agreements,” and Note 9, “Deferred Revenue,” for further discussion.
Cost of Sales
          Cost of product sales consists primarily of raw materials, third-party manufacturing costs, fill and finish costs and freight costs associated with the sales of API for ICSI Cumulase and API for HYLENEX. Cost of sales also consists of the write-down of obsolete inventory.
Research and Development Expenses
          Research and development expenses include salaries and benefits, facilities and other overhead expenses, external clinical trials, research-related manufacturing services, contract services and other outside expenses. Research and development expenses are charged to operations as incurred when these expenditures relate to the Company’s research and development efforts and have no alternative future uses. Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed or such time when the Company does not expect the goods to be delivered or services to be performed.
          Milestone payments that the Company makes in connection with in-licensed technology or product candidates are expensed as incurred when there is uncertainty in receiving future economic benefits from the licensed technology or product candidates. The Company considers the future economic benefits from the licensed technology or product candidates to be uncertain until such licensed technology or product candidates are approved for marketing by the U.S. Food and Drug Administration or comparable regulatory agencies in foreign countries or when other significant risk factors are abated. Management has viewed future economic benefits for all of the Company’s licensed technology or product candidates to be uncertain and has expensed these amounts for accounting purposes.
Clinical Trial Expenses
          Expenses related to clinical trials are accrued based on the Company’s estimates and/or representations from service providers regarding work performed, including actual level of patient enrollment, completion of patient studies and clinical trials progress. Other incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the contracted amounts are modified (for instance, as a result of changes in the clinical trial protocol or scope of work to be performed), the Company modifies its accruals accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision become reasonably certain. Historically, the Company has had no material changes in its clinical trial expense accruals that would have had a material impact on its consolidated results of operations or financial position.
Share-Based Compensation
          Share-based compensation expense is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense, net of estimated forfeitures, over the employee’s requisite service period. Total share-based compensation expense related to all of the Company’s share-based awards was allocated as follows:

          Since the Company has a net operating loss carryforward as of June 30, 2011, no excess tax benefits for the tax deductions related to share-based awards were recognized in the interim unaudited condensed consolidated statements of operations. For the three months ended June 30, 2011 and 2010, employees exercised stock options to purchase 1,222,420 and 8,728 shares of common stock, respectively, for aggregate proceeds of approximately $2.2 million, of which approximately $616,000 was included in the current prepaid expenses and other assets at June 30, 2011 and was received in July 2011, and $34,000, respectively. For the six months ended June 30, 2011 and 2010, employees exercised stock options to purchase 2,675,062 and 208,542 shares of common stock, respectively, for aggregate proceeds of approximately $4.1 million, of which approximately $616,000 was included in the current prepaid expenses and other assets at June 30, 2011 and was received in July 2011, and $497,000, respectively.
          As of June 30, 2011, total unrecognized estimated compensation cost related to non-vested stock options and non-vested restricted stock awards and restricted stock units granted prior to that date was approximately $7.0 million, and $2.2 million, respectively, which is expected to be recognized over a weighted-average period of approximately 2.6 years and approximately eleven months, respectively.
          In May 2011, the Company’s stockholders approved the Company’s 2011 Stock Plan, which provides for the granting of up to a total of 6,000,000 shares of common stock (subject to certain limitations as described in the 2011 Stock Plan) to selected employees, consultants and non-employee members of the Company’s Board of Directors (“Outside Directors”) as stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards and performance awards. The Company anticipates that the 2011 Stock Plan will be utilized for the initial equity awards for new hires of the Company as well as for annual and performance equity awards for existing employees. Options granted under the 2011 Stock Plan will generally have a 10-year term and vest at the rate of 1/4 of the shares on the first anniversary of the date of grant and 1/48 of the shares monthly thereafter.
          The 2011 Stock Plan replaced the Company’s prior stock plans, consisting of the Company’s 2008 Stock Plan, 2006 Stock Plan and 2004 Stock Plan (“Prior Plan”). The Prior Plans were terminated such that no additional awards could be granted thereunder but the terms of the Prior Plans remain in effect with respect to outstanding awards until they are exercised, settled, forfeited or otherwise canceled in full.
          Stock Options - During the three months ended June 30, 2011 and 2010, the Company granted 95,100 and 8,500 stock options, respectively, with an estimated weighted-average grant-date fair value of $3.66 and $4.68 per share, respectively. During the six months ended June 30, 2011 and 2010, the Company granted 752,768 and 1,102,214 stock options, respectively, with an estimated weighted-average grant-date fair value of $4.19 and $3.53 per share, respectively.
          Restricted Stock Awards and Restricted Stock Units - During the three and six months ended June 30, 2011, the Company granted to certain employees 233,508 restricted stock awards (“RSAs”) and 148,000 restricted stock units (“RSUs”), with a grant-date fair value of $6.67 per share (“Employee Restricted Awards”). The Employee Restricted Awards are subject to percentage vesting based upon achievement of certain corporate goals and the employees’ continuing services through May 2012. The Company also granted to its Outside Directors annual grants totaling 120,000 RSAs, with a grant-date fair value of $6.21, during the three and six months ended June 30, 2011. During the three and six months ended June 30, 2010, the Company granted to the Outside Directors annual grants totaling 120,000 RSAs, with a grant-date fair value of $7.67.
Comprehensive Income (Loss)
          Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) was the same as the Company’s net income (loss).
Fair Value Measurements
          The Company follows the authoritative guidance for fair value measurements and disclosures, which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.
          The framework for measuring fair value provides a hierarchy that prioritizes the inputs to valuation techniques used in measuring fair value as follows:
     
Level 1
  Quoted prices (unadjusted) in active markets for identical assets or liabilities;
 
   
Level 2
  Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and
 
   
Level 3
  Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.
     Cash equivalents of approximately $76.5 million and $79.8 million at June 30, 2011 and December 31, 2010, respectively, are carried at fair value and are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices for identical securities. The Company has no instruments that are classified within Level 2 or Level 3.
Collaborative Agreements
Collaborative Agreements
3.     Collaborative Agreements
Roche Partnership
          In December 2006, the Company and Roche entered into the Roche Partnership, under which Roche obtained a worldwide, exclusive license to develop and commercialize product combinations of rHuPH20 and up to thirteen Roche target compounds resulting from the partnership. Under the terms of the Roche Partnership, Roche paid $20.0 million as an initial upfront license fee for the application of rHuPH20 to three pre-defined Roche biologic targets. Due to the Company’s continuing involvement obligations (for example, support activities associated with rHuPH20 enzyme), revenues from the upfront payment, exclusive designation fees and annual license maintenance fees were deferred and are being recognized over the term of the Roche Partnership. Roche may pay the Company further payments which could potentially reach a value of up to $111.0 million for the initial three exclusive targets dependent upon the achievement of specified clinical, regulatory and sales-based milestones.
          Under the terms of the Roche Partnership, Roche will also pay the Company royalties on product sales for these first three targets. Through June 30, 2011, Roche has elected two additional exclusive targets. In 2010, Roche did not pay the annual license maintenance fee on five target slots. As a result, Roche has an option to select only three additional targets under the Roche partnership agreement, provided that Roche continues to pay annual exclusivity maintenance fees to the Company. For each of the additional five targets, Roche may pay the Company further upfront and milestone payments of up to $47.0 million per target, as well as royalties on product sales for each of these additional five targets. Additionally, Roche will obtain access to the Company’s expertise in developing and applying rHuPH20 to Roche targets. Under the terms of the Roche Partnership, the Company was obligated to scale up the production of rHuPH20 and to identify a second source manufacturer that would help meet anticipated production obligations arising from the partnership.
          The Company has determined that the clinical and regulatory milestones are substantive; therefore, the Company expects to recognize such clinical and regulatory milestone payments as revenue upon achievement of the milestones. Given the challenges inherent in developing and obtaining approval for pharmaceutical and biologic products, there was substantive uncertainty whether any of the clinical and regulatory milestones would be achieved at the time the Roche Partnership was entered into. In addition, the Company evaluated whether the clinical and regulatory milestones met the remaining criteria to be considered substantive. The Company has determined that the sales-based milestone payments are similar to royalty payments; therefore, the Company will recognize such sales-based milestone payments as revenue upon achievement of the milestone. In the three and six months ended June 30, 2011, the Company recognized $0 and $5.0 million, respectively, as revenue under collaborative agreements in accordance with the Milestone Method of revenue recognition related to the achievement of certain clinical milestones pursuant to the terms of the Roche Partnership.
Gammagard Partnership
          In September 2007, the Company entered into the Gammagard Partnership with Baxter, under which Baxter obtained a worldwide, exclusive license to develop and commercialize product combinations of rHuPH20, with a current Baxter product, GAMMAGARD LIQUID. Under the terms of the Gammagard Partnership, Baxter paid the Company a nonrefundable upfront payment of $10.0 million. Due to the Company’s continuing involvement obligations (for example, support activities associated with rHuPH20 enzyme), the $10.0 million upfront payment was deferred and is being recognized over the term of the Gammagard Partnership. Baxter may make further milestone payments totaling $37.0 million to the Company upon the achievement of regulatory approval for the licensed product candidate and specified sales volumes of commercialized product by Baxter. In addition, Baxter will pay royalties on the sales, if any, of the product that result from the collaboration. The Gammagard Partnership is applicable to both kit and formulation combinations. Baxter assumes all development, manufacturing, clinical, regulatory, sales and marketing costs under the Gammagard Partnership, while the Company is responsible for the supply of the rHuPH20 enzyme. The Company performs research and development activities at the request of Baxter, which are reimbursed by Baxter under the terms of the Gammagard Partnership. In addition, Baxter has certain product development and commercialization obligations in major markets identified in the Gammagard Partnership.
          The Company has determined that the regulatory milestones are substantive; therefore, the Company expects to recognize such regulatory milestone payments as revenue upon achievement. Given the challenges inherent in developing and obtaining approval for pharmaceutical and biologic products, there was substantive uncertainty whether any of the regulatory events would be achieved at the time the Gammagard Partnership was entered into. In addition, the Company evaluated whether the regulatory milestones met the remaining criteria to be considered substantive. The Company has determined that sales-based milestone payments are similar to royalty payments and, therefore, will be recognized as revenue upon achievement of the milestone. In the three and six months ended June 30, 2011, the Company recognized $3.0 million as revenue under collaborative agreement in accordance with the Milestone Method of revenue recognition related to the achievement of a regulatory milestone pursuant to the terms of the Gammagard Partnership.
ViroPharma and Intrexon Partnerships
          Effective May 10, 2011, the Company and ViroPharma entered into a collaboration and license agreement “ViroPharma Partnership”, under which ViroPharma obtained a worldwide exclusive license for the use of rHuPH20 enzyme in the development of a subcutaneous injectable formulation of ViroPharma’s commercialized product, Cinryze® (C1 esterase inhibitor [human]). In addition, the license provides ViroPharma with exclusivity to C1 esterase inhibition and to the Hereditary Angioedema, along with three additional orphan indications. Under the terms of the ViroPharma Partnership, ViroPharma paid a nonrefundable license fee of $9.0 million. In addition, the Company is entitled to receive an annual exclusivity fee of $1.0 million commencing on May 10, 2012 and on each anniversary of the effective date of the agreement thereafter until a certain development event occurs. ViroPharma is solely responsible for the development, manufacturing and marketing of any products resulting from this partnership. The Company is entitled to receive payments for research and development services and supply of rHuPH20 API if requested by ViroPharma. In addition, the Company is entitled to receive additional cash payments potentially totaling $44.0 million for a product for treatment of Hereditary Angioedema and $10.0 million for each product for treatment of each of the three additional orphan indications upon achievement of development and regulatory milestones. The Company is also entitled to receive royalties on future product sales by ViroPharma. ViroPharma may terminate the agreement prior to expiration for any reason on a product-by-product basis upon 90 days’ prior written notice to the Company. Upon any such termination, the license granted to ViroPharma (in total or with respect to the terminated product, as applicable) will terminate and revert to the Company.
          Effective June 6, 2011, the Company and Intrexon entered into a collaboration and license agreement “Intrexon Partnership”, under which Intrexon obtained a worldwide exclusive license for the use of rHuPH20 enzyme in the development of a subcutaneous injectable formulation of Intrexon’s recombinant human alpha 1-antitrypsin (rHuA1AT). Under the terms of the Intrexon Partnership, Intrexon paid a nonrefundable upfront license fee of $9.0 million. In addition, the Company is entitled to receive an annual exclusivity fee of $1.0 million commencing on June 6, 2012 and on each anniversary of the effective date of the agreement thereafter until a certain development event occurs. Intrexon is solely responsible for the development, manufacturing and marketing of any products resulting from this partnership. The Company is entitled to receive payments for research and development services and supply of rHuPH20 API if requested by Intrexon. In addition, the Company is entitled to receive additional cash payments potentially totaling $44.0 million for each product for use in the exclusive field and $10 million for each product for use in the non-exclusive field upon achievement of development and regulatory milestones. The Company is also entitled to receive escalating royalties on product sales and a cash payment of $10.0 million upon achievement of a specified sales volume of product sales by Intrexon. Intrexon may terminate the agreement prior to expiration for any reason on a product-by-product basis upon 90 days’ prior written notice to the Company. Upon any such termination, the license granted to Intrexon (in total or with respect to the terminated product, as applicable) will terminate and revert to the Company. Intrexon’s chief executive officer and chairman of its board of directors is also a member of the Company’s board of directors.
          In accordance with ASU No. 2009-13, the Company identified the deliverables at the inception of the ViroPharma and Intrexon agreements which are the license, research and development services and API supply. The Company has determined that the license, research and development services and API supply individually represent separate units of accounting, because each deliverable has standalone value. The estimated selling prices for these units of accounting was determined based on market conditions, the terms of comparable collaborative arrangements for similar technology in the pharmaceutical and biotech industry and entity-specific factors such as the terms of the Company’s previous collaborative agreements, the Company’s pricing practices and pricing objectives and the nature of the research and development services to be performed for the partners. The arrangement consideration was allocated to the deliverables based on the relative selling price method. Based on the results of the Company’s analysis, the Company determines that the upfront payment was earned upon the granting of the worldwide exclusive right to the Company’s technology to the collaborator in both the ViroPharma Partnership and Intrexon Partnership. However, the amount of allocable arrangement consideration is limited to amounts that are fixed or determinable; therefore, the amount allocated to the license at June 30, 2011 was only to the extent of cash received. As a result, the Company recognized the $9.0 million upfront license fee received under the ViroPharma Partnership and the $9.0 million upfront license fee received under the Intrexon Partnership as revenues under collaborative agreements in the quarter ended June 30, 2011.
          The Company will recognize the exclusivity fees as revenues under collaborative agreements when they are earned. The Company will recognize reimbursements for research and development services as revenues under collaborative agreements as the related services are delivered. The Company will recognize revenue from sales of API as revenues under collaborative agreements when such API has met all required specifications by the partners and the related title and risk of loss and damages have passed to the partners. The Company cannot predict the timing of delivery of research and development services and API as they are at the partners’ requests.
          The Company is eligible to receive additional cash payments upon the achievement by the partners of specified development, regulatory and sales-based milestones. The Company has determined that each of the development and regulatory milestones is substantive; therefore, the Company expects to recognize such development and regulatory milestone payments as revenues under collaborative agreements upon achievement in accordance to the milestone method of revenue recognition. Given the challenges inherent in developing and obtaining approval for pharmaceutical and biologic products, there was substantive uncertainty whether any of the development and regulatory milestones would be met at the time these partnerships were entered into, and the milestones are based in part on the occurrence of a separate outcome resulting from the Company’s performance. In addition, the Company evaluated whether the development and regulatory milestones met the remaining criteria to be considered substantive. The Company has determined that the sales-based milestone payment is similar to a royalty payment; therefore, the Company will recognize the sales-based milestone payment as revenue upon achievement of the milestone because the Company has no future performance obligations associated with the milestone.

          Roche Partnership - In December 2006, the Company and Roche entered into the Roche Partnership under which Roche obtained a worldwide, exclusive license to develop and commercialize product combinations of rHuPH20and up to thirteen Roche target compounds. Under the terms of the Roche Partnership, Roche paid $20.0 million to the Company in December 2006 as an initial upfront payment for the application of rHuPH20 to three pre-defined Roche biologic targets. Through June 30, 2011, Roche has paid an aggregate of $19.25 million in connection with Roche’s election of two additional exclusive targets and annual license maintenance fees for the right to designate the remaining targets as exclusive targets. In 2010, Roche did not pay the annual license maintenance fees on five of the remaining eight target slots. As a result, Roche currently retains the option to exclusively develop and commercialize rHuPH20 with three additional targets through the payment of annual license maintenance fees.
     Due to the Company’s continuing involvement obligations (for example, support activities associated with rHuPH20 enzyme), revenues from the upfront payment, exclusive designation fees and annual license maintenance fees were deferred and are being recognized over the term of the Roche Partnership. The Company recognized revenue from the upfront payment, exclusive designation fees and annual license maintenance fees under the Roche Partnership in the amounts of approximately $491,000 and $530,000 for the three months ended June 30, 2011 and 2010, respectively, and approximately $983,000 and $1.1 million for the six months ended June 30, 2011 and 2010, respectively. Deferred revenue relating to the upfront payment, exclusive designation fees and annual license maintenance fees under the Roche Partnership was $31.9 million and $32.9 million as of June 30, 2011 and December 31, 2010, respectively.
          Baxter Partnerships - In September 2007, the Company and Baxter entered into the Gammagard Partnership, under which Baxter obtained a worldwide, exclusive license to develop and commercialize product combinations of rHuPH20 with GAMMAGARD LIQUID. Under the terms of the Gammagard Partnership, Baxter paid the Company a nonrefundable upfront payment of $10.0 million. Due to the Company’s continuing involvement obligations (for example, support activities associated with rHuPh20 enzyme), the $10.0 million upfront payment was deferred and is being recognized over the term of the Gammagard Partnership. The Company recognized revenue from the upfront payment under the Gammagard Partnership in the amounts of approximately $121,000 and $140,000 for the three months ended June 30, 2011 and 2010, respectively, and approximately $241,000 and $279,000 for the six months ended June 30, 2011 and 2010. Deferred revenue relating to the upfront payment under the Gammagard Partnership was $7.8 million and $8.1 million as of June 30, 2011 and December 31, 2010, respectively.
          In February 2007, the Company and Baxter amended certain existing agreements for HYLENEX and entered into the HYLENEX Partnership for kits and formulations with rHuPH20. Under the terms of the HYLENEX Partnership, Baxter paid the Company a nonrefundable upfront payment of $10.0 million. In addition, Baxter would make payments to the Company based on sales of the products covered under the HYLENEX Partnership. Baxter had prepaid nonrefundable product-based payments totaling $10.0 million in connection with the execution of the HYLENEX Partnership. Due to the Company’s continuing involvement obligations (for example, support activities associated with rHuPh20 enzyme), the $10.0 million upfront payment was initially deferred and was being recognized over the term of the HYLENEX Partnership. The prepaid product-based payments were also deferred and were being recognized as product sales revenues as the Company earned such revenues from the sales of HYLENEX by Baxter.
          Effective January 7, 2011, the Company and Baxter mutually agreed to terminate the HYLENEX Partnership and the associated agreements. The termination of these agreements does not affect the other relationships between the parties, including the application of Halozyme’s Enhanze Technology to Baxter’s GAMMAGARD LIQUID. As a result, in the fourth quarter ended December 31, 2010 the Company recharacterized deferred revenue of approximately $991,000 as a reserve for product returns for HYLENEX API previously delivered to Baxter that could be returned (“Delivered Products”). For the three months ended June 30, 2011 and 2010, the Company recognized revenues under the HYLENEX Partnership from the upfront payment in the amounts of approximately $117,000 and $135,000, respectively. No revenues were recognized from the product-based payments for the three months ended June 30, 2011 and 2010. For the six months ended June 30, 2011 and 2010, the Company recognized revenues under the HYLENEX Partnership from the upfront payment in the amounts of approximately $233,000 and $270,000, respectively, and from the product-based payments in the amounts of approximately zero and $332,000, respectively.
          On July 18, 2011, the Company and Baxter entered into an agreement (the “Transition Agreement”) setting forth certain rights, data and assets to be transferred by Baxter to the Company during a transition period. In addition, in June 2011 the Company also entered into a commercial manufacturing and supply agreement with Baxter, under which Baxter will fill and finish HYLENEX for the Company. Effective July 18, 2011, the Company has no future performance obligations in connection with the HYLENEX Partnership. Therefore, the Company has classified the unamortized deferred revenue of approximately $9.3 million relating to the prepaid product-based payments and the unamortized deferred revenue of approximately $7.6 million relating to deferred upfront payment as current deferred revenue at June 30, 2011 and will recognize such amounts as revenues under collaborative agreements in the quarter ending September 30, 2011. In addition, pursuant to the terms of the Transition Agreement, Baxter no longer has the right to return the Delivered Products. Accordingly, the Company recharacterized the reserve for product returns for the Delivered Products of approximately $991,000 to current deferred revenue at June 30, 2011 and will recognize as product sales revenue in the quarter ending September 30, 2011.
Net Income (Loss) Per Share
Net Income (Loss) Per Share
8.     Net Income (Loss) Per Share
          Basic net income (loss) per common share (“EPS”) is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net income (loss) per common share is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding. Dilutive potential common shares outstanding, determined using the treasury stock method, principally include: shares that may be issued under the Company’s stock option, restricted stock and restricted stock units. For the three months ended June 30, 2011 and 2010, the Company has excluded approximately 2.0 million and 8.9 million shares, respectively, of stock options, unvested RSAs and RSUs from the computation of diluted EPS because their impact would have been anti-dilutive. In the six months ended June 30, 2011 and 2010, the Company has excluded approximately 6.0 million and 8.9 million shares of stock options, unvested RSAs and RSUs from the computation of diluted EPS as their impact would have been anti-dilutive because of the Company’s net loss in these reporting periods.. The following table sets forth the computation for basic and diluted EPS:
