Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Business Activities and Organization Pfenex Inc. (the Company or Pfenex) is a clinical-stage development and licensing biotechnology company focused on leveraging its Pf ēnex Expression Technology ® to develop and improve protein therapies for unmet patient needs. Using the patented Pf ēnex Expression Technology platform, the Company has created an advanced pipeline of potential therapeutic equivalents, novel biologics, vaccine and vaccine components, and biosimilars. The Company’s lead product candidate is PF708, a therapeutic equivalent candidate to Forteo ® (teriparatide) for the treatment of osteoporosis. In addition, in collaboration with Jazz Pharmaceuticals Ireland Limited (Jazz) the Company is developing oncology products including PF743, a recombinant crisantaspase, and PF745, a recombinant crisantaspase with half-life extension. Both PF743 and PF745 are being developed for the treatment of Acute Lymphoblastic Leukemia (ALL). Pf Proposed Therapeutic Equivalent: PF708 – Teriparatide PF708 is being developed as a therapeutic equivalent candidate to Forteo, which is approved and marketed by Eli Lilly and Company for the treatment of osteoporosis patients at a high risk of fracture. In December 2018, the Company submitted its new drug application (NDA) for Forteo to the United States Food and Drug Administration (FDA) and the FDA accepted the submission for substantive review in February 2019. In April 2018, the Company and China NT Pharma Group Company Ltd. (NT Pharma) entered into a Development and License Agreement (NT Pharma Agreement), pursuant to which the Company granted an exclusive license to NT Pharma to commercialize PF708 in Mainland China, Hong Kong, Singapore, Malaysia and Thailand and a non-exclusive license to conduct development activities in such territories with respect to PF708. The Company will be responsible for commercial manufacturing and will provide NT Pharma with the product for commercial sale. NT Pharma will be responsible for all regulatory submissions, development costs and costs associated with regulatory approvals in such territories. In June 2018, the Company and Alvogen Malta Operations Ltd. (Alvogen) entered into a Development and License Agreement (Alvogen Agreement) pursuant to which Alvogen has the exclusive right to commercialize and manufacture PF708 in the United States. The Company will continue to be responsible for development and registration of PF708 in the US, while Alvogen will provide regulatory and development expertise. In February 2019, the Company and Alvogen entered into additional agreements, extending Alvogen’s rights to commercialize and manufacture PF708 to include the European Union (EU), certain countries in the Middle East and North Africa (MENA) and to the rest of world (ROW) territories (excluding certain Asian countries granted to NT Pharma). Alvogen is responsible for local activities and for overseeing any clinical development, regulatory, litigation, commercial manufacturing and commercialization. Collaboration Partner: Jazz Pharmaceuticals Ireland Limited In July 2016, the Company and Jazz announced an agreement under which the Company granted Jazz worldwide rights to develop and commercialize multiple early stage hematology/oncology product candidates, including PF743, a recombinant crisantaspase, and PF745, a recombinant crisantaspase with half-life extension technology. In December 2017, the parties amended the Jazz agreement, bringing the total value of payments and potential payments associated with the collaboration to $224.5 million. In addition, the Company may be eligible to receive tiered royalties on worldwide sales of any products resulting from the collaboration at rates reduced from those under the 2016 agreement. Pfēnex Expression Technology Licenses: CRM 197 The Company has several development and commercial partnerships in place for CRM197, which is a non-toxic mutant of diphtheria toxin. It is a well-characterized protein and functions as a carrier for polysaccharides and haptens, making them immunogenic. The Company developed a unique CRM197 production strain based on its Pseudomonas fluorescens platform and sells non-GMP and cGMP CRM197 to vaccine development-focused pharmaceutical partners. As a result of those efforts, the Company previously entered into commercial licenses for production strains capable of producing CRM197 with both Merck & Co., Inc. (Merck) and Serum Institute of India Private, Ltd (SIIPL). These commercial license agreements with Merck and SIIPL contemplate potential maintenance and milestone fees as well as royalties on net sales. Merck and SIIPL are currently using the Company’s CRM197 in multiple Phase 3 clinical trials for such diseases as pneumococcal and meningitis bacterial infections. The Company expects revenue in the near term to be primarily related to monetizing its protein production platform through CRM197 product sales, commercial license agreements, service agreements, and government contracts, which may provide for various types of payments, including upfront payments, funding of research and development, milestone payments, intellectual property access fees and licensing fees. Additional Novel Vaccine and Biosimilar Pipeline Products The Company has also been developing Px563L and RPA563, novel anthrax vaccine candidates, in response to the United States government’s unmet demand for increased quantity, stability and dose-sparing regimens of anthrax vaccine . The government contract is funded by the Biomedical Advanced Research and Development Authority (BARDA). The Company had initially entered into a development contract with BARDA in 2010. The $25.2 million fully-funded contract was completed in 2015, at which time BARDA awarded the Company a cost-plus fixed fee advanced development contract valued at up to approximately $143.5 million. In January 2017, BARDA exercised two options under its existing contract for further development of Px563L and RPA563. One of the exercised options was increased by $1.7 million in May 2018, which increased the total contract value to $145.2 million. In September 2018, BARDA extended the contract period of performance to December 2019. On March 29, 2019, the Company received notice from BARDA advising the Company of its decision not to exercise development options for cGMP manufacturing and potential Phase 1/2b study readiness for Px563L and RPA563. Following the receipt of the notice from BARDA and pursuant to ongoing discussions with BARDA, the Company is assessing the priority of this program in its portfolio. The Company’s pipeline includes biosimilar candidates to certain reference products, including biosimilar candidates to Lucentis and Neulasta. Following the Company’s strategic review in November 2017, the Company decided to pause development activities on PF582, its biosimilar candidate to Lucentis and PF529, its biosimilar candidate to Neulasta, and focus development efforts elsewhere within the product portfolio while the Company continued to engage potential strategic partners to advance the programs and maximize value. The Company does not intend to advance its current biosimilar candidates without development and commercial collaboration partners. At the Market Offering Program In March 2018, the Company entered into an equity sales agreement (Sales Agreement) with William Blair & Company, L.L.C. (William Blair) to sell shares of the Company’s common stock having aggregate sales proceeds of up to $20.0 million, from time to time, through an “at the market” equity offering program under which William Blair will act as sales agent. Under the Sales Agreement, the Company sets the parameters for the sale of shares, including the number of shares to be issued, the time period during which sales are requested to be made, limitation on the number of shares that may be sold in any one trading day and any minimum price below which sales may not be made. As of March 31, 2019, the Company had not sold any shares under the Sales Agreement. Follow-on Public Offering In May 2018, the Company completed a public offering of common stock in which it sold 7,820,000 shares of its common stock at an offering price of $5.50 per share, which included the full exercise by the underwriters of their option to purchase an additional 1,020,000 shares, pursuant to the Company’s existing shelf registration statement. The net proceeds generated from this transaction, after underwriting discounts and commissions and offering costs, were approximately $39.5 million. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions of the Securities and Exchange Commission, or SEC, on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments necessary, which are of a normal and recurring nature, for the fair presentation of the Company’s financial position and of the results of operations and cash flows for the periods presented. These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the SEC. The results of operations for the interim period shown in this report are not necessarily indicative of the results that may be expected for any other interim period or for the full year. Use of Estimates The preparation of the accompanying unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts (including assets, liabilities, revenues and expenses) and related disclosures. Estimates have been prepared on the basis of the most current and best available information. However, actual results could differ from those estimates. Risk and Uncertainties The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of results of clinical trials and reaching milestones, uncertainty of regulatory approval of the Company’s product candidates, uncertainty of market acceptance of the Company’s products if approved for sale, competition from substitute products and larger companies, securing and protecting proprietary technology, strategic relationships and dependence on key individuals. Products developed by the Company require clearances from international and domestic regulatory agencies prior to commercial sales in such jurisdictions. There can be no assurance that the products will receive the necessary clearances. If the Company was denied clearance, clearance was delayed or the Company was unable to maintain clearance, it could have a materially adverse impact on the Company. As of March 31, 2019, the Company had an accumulated deficit of $205.0 million and expects to incur substantial operating losses for the next several years. The Company believes that its existing cash and cash equivalents and cash inflow from operations will be sufficient to meet its anticipated cash needs for at least the next 12 months from the date these unaudited consolidated financial statements are issued, including all of the Company’s necessary obligations for PF708 leading up to its potential commercial launch in the United States as early as the fourth quarter of 2019, subject to FDA approval of the NDA and other factors. The Company will require substantial cash to achieve its objectives of discovering, developing and commercializing drugs, as this process typically takes many years and potentially hundreds of millions of dollars for an individual drug. The Company may not have adequate available cash, or assets that could be readily turned into cash, to meet these objectives in the long term. It will need to obtain significant funds under its existing collaborations and license agreements, under new collaboration, licensing or other commercial agreements for one or more of its drug candidates and programs or patent portfolios, or from other potential sources of liquidity, which may include the sale of equity, issuance of debt or other transactions. However, there can be no assurance that any additional financing or strategic investments will be available to the Company on acceptable terms, if at all. If events or circumstances occur such that it does not obtain additional funding, the Company will most likely be required to reduce its plans and/or certain discretionary spending, which could have a material adverse effect on its ability to achieve its intended business objectives. Cash and Cash Equivalents The Company considers all highly liquid investments that are readily convertible into cash and have an original maturity of 90 days or less at the time of purchase to be cash equivalents. Cash amounts that are restricted as to withdrawal or usage are presented as restricted cash. In January 2017, the Company entered into a Borrower’s Pledge Agreement, which required $0.2 million in restricted cash to be provided as security for its commercial credit card arrangement with one of the Company’s banks. Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments and accounts and unbilled receivables. The Company has established guidelines intended to limit its exposure to credit risk by placing investments with high credit quality financial institutions, diversifying its investment portfolio and placing investments with maturities that help maintain safety and liquidity. All cash and cash equivalents were held at three major financial institutions as of March 31, 2019 and December 31, 2018. For the Company’s cash position of $46.0 million as of March 31, 2019, which included restricted cash of $0.2 million, the Company has exposure to credit loss for amounts in excess of insured limits in the event of non-performance by the institutions; however, the Company does not anticipate non-performance. Additional credit risk is related to the Company’s concentration of receivables. As of March 31, 2019 and December 31, 2018, receivables were concentrated among two and three customers representing 85% and 87% of total net receivables, respectively. No allowance for doubtful accounts was recorded at March 31, 2019 or December 31, 2018. Revenue from three and two customers and/or collaboration partners represented 74% and 90% of total revenue for the three months ended March 31, 2019 and 2018, respectively. A portion of revenue is earned from sales outside the United States. Non-U.S. revenue is denominated in U.S. dollars. A breakdown of the Company’s revenue from U.S. and non-U.S. sources for the three months ended March 31, 2019 and 2018 is as follows: Three Months Ended March 31, 2019 2018 (in thousands) US Revenue $ 2,275 $ 1,594 Non-US Revenue 8,087 2,152 $ 10,362 $ 3,746 During the three months ended March 31, 2019 and 2018, Ireland accounted for more than 10% of the Company’s revenue. 2019, Malta and China also accounted for more than 10% of the Company’s revenue. Fair Value of Financial Instruments Financial instruments, including cash, cash equivalents, restricted cash and the lines of credit, are carried at cost, which management believes approximates fair value because of the short-term maturity of these instruments Fair value is an exit price, representing the amount 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. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows: • Level 1—Observable inputs such as quoted prices in active markets for identical assets or liabilities. Level 1 assets at March 31, 2019 and December 31, 2018 included the Company’s cash, cash equivalents and restricted cash. There were no Level 1 liabilities; • Level 2—Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly. The Company had no Level 2 assets or liabilities at March 31, 2019 or December 31, 2018; and • Level 3—Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities in which there is little or no market data. The Company had no Level 3 assets or liabilities at March 31, 2019 or December 31, 2018. Revenue The Company’s revenue is related to the monetization of its protein production platform through collaboration agreements, service agreements, license agreements, government contracts and sales of reagent protein products, which may provide for various types of payments, including upfront payments, funding of research and development, milestone payments, intellectual property access fees and licensing fees. The Company’s revenue generating agreements also include potential revenues for achieving milestones and for product royalties. The specifics of the Company’s significant agreements are detailed in Note 7—Significant Research and Development Agreements. The Company considers a variety of factors in determining the appropriate method of accounting for its collaboration agreements, including whether multiple deliverables can be separated and accounted for individually as separate units of accounting. Where there are multiple deliverables within a collaboration agreement that cannot be separated and therefore are combined into a single unit of accounting, revenues are deferred and recognized using the relevant guidance over the estimated period of performance. If the deliverables can be separated, the Company applies the relevant revenue recognition guidance to each individual deliverable. The specific methodology for the recognition of the underlying revenue is determined on a case-by-case basis according to the facts and circumstances applicable to each agreement. On a quarterly basis, the Company evaluates the period of performance to determine if a change should be made. Upfront, nonrefundable licensing payments are assessed to determine whether or not the licensee is able to obtain standalone value from the license. Where the license does not have standalone value, non-refundable license fees are recorded as deferred revenue and recognized as revenue as the Company performs under the applicable agreement. Where the level of effort is relatively consistent over the performance period, the Company recognizes fixed or determined revenue on a straight-line basis over the estimated period of performance. Where the license has standalone value, the Company recognizes total license revenue at the time all revenue recognition criteria have been met. Nonrefundable payments for research funding are generally recognized as revenue over the period the underlying research activities are performed. Revenue under service agreements are recorded as services are performed. These agreements do not require development achievement as a performance obligation and provide for payment when services are rendered. All such revenue is nonrefundable. Upfront, nonrefundable payments for license fees, exclusivity and feasibility services received in excess of amounts earned are classified as deferred revenue and recognized as income over the contract term or period of performance based on the nature of the related agreement. The Company recognizes revenue for its cost-plus fixed fee government contracts in accordance with the authoritative guidance for revenue recognition including the authoritative guidance specific to federal government contractors. Reimbursable costs under the Company’s government contracts primarily include direct labor, materials, subcontracts, accountable property and indirect costs. In addition, the Company receives a fixed fee under its government contracts, which is unconditionally earned as allowable costs are incurred and is not contingent on success factors. Reimbursable costs under the Company’s government contracts, including the fixed fee, are generally recognized as revenue in the period the reimbursable costs are incurred. The Company assesses milestone payments on an individual basis and recognizes revenue from nonrefundable milestone payments when the earnings process is complete and the payment is reasonably assured. Nonrefundable milestone payments related to arrangements under which the Company has continuing performance obligations are recognized as revenue upon achievement of the associated milestone, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, and (ii) the amount of the milestone payment is reasonable in relation to the effort expended or the risk associated with the milestone event. For the three months ended March 31, 2019, The Company’s reagent protein products are primarily comprised of internally developed reagent protein products. Revenues for reagent product sales are reflected net of attributable sales tax. The Company generally offers a 30 day return policy. The Company recognizes reagent product revenue from product sales when it is realized or realizable and earned. As of March 31, 2019, the Company has had minimal product returns related to reagent protein product sales. Therefore, no reserve for warranty and return rights was recorded as of March 31, 2019 and December 31, 2018, respectively. Revenue under arrangements where the Company outsources the cost of fulfillment to third parties is evaluated as to whether the related amounts should be recorded gross or net. The Company records amounts collected from the customer as revenue, and the amounts paid to suppliers as cost of revenue when it holds all or substantially all of the risks and benefits related to the product or service. For transactions where the Company does not hold all or substantially all the risk, the Company uses net reporting and therefore records the transaction as if the end-user made a purchase from the supplier with the Company acting as a sales agent. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This updated guidance eliminates Step 2 from the current two-step quantitative model for goodwill impairment tests. Step 2 required an entity to calculate an implied fair value, which included a hypothetical purchase price allocation requirement, for reporting units that failed Step 1. Per this updated guidance, a goodwill impairment will instead be measured as the amount by which a reporting unit’s carrying value exceeds its fair value as identified in Step 1. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this guidance is not expected to have a material impact on the consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718), which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The standard will be effective for the Company in the first quarter of fiscal year 2020, although early adoption is permitted (but no sooner than the adoption of Topic 606). The adoption of this guidance is not expected to have a material impact on the consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. The Company is currently evaluating this guidance to determine the impact on its financial statements and related disclosures. In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808)—Clarifying the Interaction between Topic 808 and Topic 606 . The amendments in ASU No. 2018-18 make targeted improvements to generally accepted accounting principles for collaborative arrangements by clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue under Accounting Standard Codification 606, Revenue from Contracts with Customers , or ASC 606, when the collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in ASC 606 should be applied, including recognition, measurement, presentation, and disclosure requirements. In addition, unit-of-account guidance in ASC 808 was aligned with the guidance in ASC 606 when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of ASC 606. ASU No. 2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The amendments in ASU No. 2018-18 are required to be applied retrospectively to the date of initial application of ASC 606. The Company is currently evaluating the impact of ASU No. 2018-08 on its consolidated financial statements. |
