Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Basis of presentation

The accompanying unaudited condensed consolidated financial statements reflect the accounts of Seattle Genetics, Inc. and its wholly-owned subsidiary, Seattle Genetics UK, Ltd. (collectively “Seattle Genetics” or the “Company”). These financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, or SEC, and generally accepted accounting principles for unaudited condensed consolidated financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete consolidated financial statements. These financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s financial position and results of its operations, as of and for the periods presented. Management has determined that the Company operates in one segment; the development of pharmaceutical products on its own behalf or in collaboration with others.

Unless indicated otherwise, all amounts presented in financial tables are presented in thousands, except for per share amounts.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007 as filed with the Securities and Exchange Commission.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts. Actual results could differ from those estimates. The results of the Company’s operations for the three month and six month periods ended June 30, 2008 are not necessarily indicative of the results to be expected for a full year.

2. Recent Accounting Pronouncements

In May 2008, the FASB issued Statement No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (“FAS 162”). FAS 162 identifies the sources of accounting principles and the framework for selecting the principles used (order of authority) in the preparation of financial statements that are presented in conformity with generally accepted accounting principles in the United States. FAS 162 is effective 60 days following the Securities and Exchange Commission’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, “The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles.” The Company does not expect the adoption of FAS 162 to have a material impact on its financial statements.

Effective January 1, 2008, the Company adopted EITF Issue No. 07-3, “Accounting for Nonrefundable Advance Payments for Goods or Services to Be Used in Future Research and Development Activities.” Under EITF 07-3, nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are capitalized and recognized as expense as the related goods are delivered or the related services are performed. The Company’s adoption of EITF Issue No. 07-3 results in the temporary deferral of charges to expense of amounts incurred for research and development activities from the time payouts are made until the time goods or services are provided.

In March 2008, the FASB issued SFAS No. 161 “Disclosures about Derivative Instruments and Hedging Activities” which requires enhanced disclosures about (a) how and why derivative instruments are used, (b) how derivative instruments and related hedged items are accounted for and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flows. SFAS No. 161 will be effective for the Company beginning in January 2009. The Company’s adoption of SFAS No.161 is not expected to have a material effect on its financial statements since it currently does not have any derivative instruments or hedging activities.

In November 2007, the Emerging Issues Task Force Board ratified EITF Issue No. 07-1, “Accounting for Collaborative Arrangements Related to the Development and Commercialization of Intellectual Property.” Under EITF 07-1, the Company will disclose the nature and purpose of its co-development collaborative arrangements in the annual financial statements, its rights and obligations under collaborative arrangements, the stage of the underlying endeavor’s life cycle, the Company’s accounting policies for the arrangements and the statement of operations classification and significant financial statement amounts related to the collaborative arrangements. EITF 07-1 will be effective for the Company beginning in January 2009 and will require the Company to apply this Issue as a change in accounting principle through retrospective application to all prior periods for all collaborative arrangements existing as of the effective date. The Company is currently assessing the impact of EITF 07-1 on its results of operations, cash flows and financial condition.

3. Net loss per share

Basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The Company has excluded all convertible preferred stock, warrants and options to purchase common stock from the calculation of diluted net loss per share as such securities are antidilutive for all periods presented.

The following table presents the weighted-average shares that have been excluded from the number of shares used to calculate basic and diluted net loss per share (in thousands):

The Company’s holdings in auction rate securities, or ARS, have stated final maturities in 2017, but are subject to interest rate resets and sale over time intervals of 28 days. Investments in ARS valued at $14.4 million have failed at auction. As a result of the failed auctions, these investments are currently illiquid and the interest rate on the investment is no longer determined by auction, but is set according to the terms of the issue (currently at the London Interbank Offering Rate plus 50 basis points). Liquidity of these investments is subject to either a successful auction process, redemption of the investment, or a sale of the security in a secondary market. As of June 30, 2008, the failed ARS each carry “AAA” ratings and continue to pay interest according to the stated terms on a monthly basis. ARS are presented at fair value which is based on a probability-weighted discounted cash flow analysis that relies upon certain estimates, including the probability-weighted term to settle and the discount rate applied to future cash flows. Based on the Company’s available cash, expected operating cash requirements, its belief that its holdings in ARS can be liquidated in approximately one year through a successful auction or redemption at par and its ability and intent to hold such investments until liquidation, the Company believes that the current illiquidity of these investments is temporary. However, due to the uncertainty in the liquidation period, investments in ARS are presented as long-term investments in the accompanying financial statements. The Company periodically reviews the assumptions used to determine fair value and classification of these securities based on several factors, including the continued failure of future auctions, failure of the investment to be redeemed, the credit rating of the investment, market risk and other factors. Future assessment of these assumptions may change the balance sheet classification of the investments or result in a conclusion that these investments are more than temporarily impaired which would result in a write down in the fair value of these investments and a corresponding loss that would be recognized in the Company’s operating results.

The Company has determined that unrealized losses are temporary and insignificant as to the extent of the decline, in both dollars and percentage of cost, and the Company has the ability and intent to hold its investments until it recovers at least substantially all of the cost of the investment. As of June 30, 2008, the period of continuous unrealized losses is less than twelve months.

The Company holds short term and long term available-for-sale securities that are measured at fair value which is determined on a recurring basis under Statement of Financial Accounting Standards (SFAS) No. 157, “Fair Value Measurement.” SFAS 157 establishes a fair value hierarchy that prioritizes the inputs and assumptions used, and the valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under SFAS No. 157 are described as follows:

 

Level 1    Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2    Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly;
Level 3    Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

Table of Contents

The determination of a financial instrument’s level within the fair value hierarchy is based on an assessment of the lowest level of any input that is significant to the fair value measurement. The Company’s investment securities are classified within Level 1 or Level 2 of the fair value hierarchy prescribed by SFAS No. 157 because the value of the securities is based on quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The following table presents the Company’s available-for-sale securities by level within the fair value hierarchy of FAS No. 157 as of June 30, 2008 (in thousands):

Level 1 investments, which include investments that are valued based on quoted market prices in active markets, include most U.S. government and agency securities. Level 2 investments, which include investments that are valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency, include most investment-grade corporate bonds, taxable municipal bonds, commercial paper and auction-rate securities. The Company does not currently hold any Level 3 investments which would include investments that are valued based on assumptions that are unobservable.

6. Collaborative agreements

In April 2002, the Company entered into a collaboration agreement with Genentech, Inc. granting it rights to use the Company’s antibody-drug conjugate, or ADC, technology. In June 2008, Genentech filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for an ADC utilizing the Company’s ADC technology, triggering a milestone payment to the Company. Additionally, the Company received a pre-clinical milestone payment in May 2008 from Genentech for an ADC using the Company’s ADC technology. These milestone payments will be recognized as revenue over the remaining research term of the collaboration agreement using a time-based approach.

In June 2004, the Company entered into a collaboration agreement with CuraGen Corporation granting it rights to use the Company’s ADC technology. In April 2008, CuraGen initiated a phase II clinical trial of CR011-vcMMAE, an ADC for the treatment of metastatic melanoma, triggering a milestone payment to the Company. As the Company has no substantive continuing performance obligations under this agreement, this milestone payment was recognized as revenue in the second quarter of 2008.

In April 2008, the Company entered into a First Amendment to the Development and Supply Agreement with Abbott Laboratories, Inc., to manufacture the antibody component of the Company’s SGN-35 antibody-drug conjugate product candidate. Under the terms of the First Amendment, Abbott has agreed to perform GMP manufacturing to support future development activities and clinical trials of SGN-35. The Company’s total payments to Abbott under the First Amendment are expected to be approximately $7.3 million. In May 2008, the Company entered into a First Amendment to the Development and Supply Agreement with Abbott to manufacture the Company’s SGN-40 monoclonal antibody. Under the terms of the agreement, Abbott has agreed to perform GMP manufacturing of SGN-40 with total payments to Abbott expected to be approximately $4.1 million. The Company will be reimbursed by Genentech for the costs of the SGN-40 manufacturing pursuant to the collaboration agreement with Genentech. Payments under these Abbott agreements will be expensed over the term of the arrangement as the materials are delivered and services rendered.

In September 2004, the Company entered into an ADC collaboration with Bayer Pharmaceuticals Corporation. Under the terms of the multi-year agreement, Bayer paid the Company an upfront fee of $2.0 million for an exclusive license to the Company’s ADC technology for a single antigen. The upfront fee was recognized as revenue over the three year research period that ended in September 2007. In May 2008, the Company entered into a First Amendment to the collaboration agreement with Bayer. Under the terms of the amendment, Bayer paid the Company a fee to extend the research term of the agreement for an additional one year period to evaluate the use of additional targeting agents with the Company’s ADC technology to the same antigen covered by the collaboration agreement. Bayer pays material supply and research support fees for any assistance provided by the Company in developing ADC products, as well as annual maintenance fees. The extension fee, material supply and research support fees and other payments received are recognized as revenue over the research term of the agreement using a time-based approach. Bayer is responsible for research, product development, manufacturing and commercialization of all products under the collaboration and may make progress-dependent milestone payments and pay royalties on net sales of resulting ADC products.

7. Subsequent Events

On July 2, 2008, the Company entered into an ADC collaboration agreement with Daiichi Sankyo Co. Ltd. Under the terms of the multi-year agreement, the Company received a $4.0 million upfront fee for an exclusive license to its ADC technology to a single antigen target. Daiichi Sankyo will pay the Company progress-dependent milestones, annual maintenance fees and support fees as its ADC product candidates progress through development and royalties on product sales. The upfront fee and other payments received will be recorded as revenue over the three year development term of the collaboration agreement using a time based approach.

In December 2000, the Company leased an approximately 63,900 square foot facility used for its laboratory, discovery, research and development and general and administrative purposes. On July 1, 2008, the Company entered into a lease amendment to extend and modify the terms of this lease. The lease amendment provides for a reduction in the current base rent, an extension of the lease term to June 2018 and a reduction in level of security pledged by the Company under the lease. The Company is also entitled to receive a tenant improvement allowance which will be used to offset the cost of improvements to be made to the facility to accommodate the Company’s growth. The Company has two renewal options of five years each and has the option to terminate the lease effective June 2013 or June 2015 upon providing notice of its intent to accelerate the termination date of the lease and payment of a termination fee.

In June 2007, the Company entered into an operating lease for approximately 25,000 square feet of additional office space. The lease expires in June 2018 with two extension options, the first option for three years and the second option period for seven years. The lease allows for options to terminate the lease effective June 2011 or June 2014. In July 2008, the Company amended this lease to include an additional 25,000 square feet of office space under the same terms as the original lease.

In evaluating these statements, you should specifically consider various factors, including the risks outlined under the caption “Risk Factors” set forth in Item 1A. of Part I of our Form 10-K for the fiscal year ended December 31, 2007, as well as those contained from time to time in our other filings with the SEC. We caution investors that our business and financial performance are subject to substantial risks and uncertainties.

Overview

Seattle Genetics is a clinical-stage biotechnology company developing monoclonal antibody-based therapies for the treatment of cancer and autoimmune disease. Our business strategy is focused on advancing our portfolio of product candidates in diseases with unmet medical need and significant market potential. We have a worldwide collaboration agreement with Genentech to develop and commercialize our product candidate SGN-40. In addition, we currently have three other proprietary product candidates in ongoing clinical trials, SGN-33, SGN-35 and SGN-70, as well as several lead preclinical product candidates, including SGN-75 and an anti-CD19 antibody-drug conjugate. Our pipeline of product candidates is based upon two technologies: engineered monoclonal antibodies and monoclonal antibody-drug conjugates, or ADCs. These technologies enable us to develop monoclonal antibodies that can kill target cells on their own as well as to increase the potency of monoclonal antibodies by linking them to a cell-killing payload to form an ADC. In addition to our internal pipeline, we have ADC license agreements with a number of leading biotechnology and pharmaceutical companies, including Genentech, Inc., Bayer Pharmaceuticals Corporation, CuraGen Corporation, Progenics Pharmaceuticals, Inc., Daiichi Sankyo Co Ltd., and MedImmune Inc., a wholly-owned subsidiary of AstraZeneca PLC, as well as an ADC co-development agreement with Agensys, Inc., a wholly-owned subsidiary of Astellas Pharma.

We do not currently have any commercial products for sale. All of our product candidates are in relatively early stages of development and significant further research and development, financial resources and personnel will be required to develop commercially viable products and obtain regulatory approvals. As of June 30, 2008, we had an accumulated deficit of $261.7 million. Over the next several years, we expect to incur substantial expenses as we continue to invest in research, development and manufacturing and move towards commercialization of our product candidates. Our commitment of resources to research and the continued development and potential commercialization of our product candidates will require substantial additional funds and resources. Our operating expenses will also likely increase as we invest in research or acquire additional technologies, as additional product candidates are selected for clinical development and as some of our earlier stage product candidates move into later stage clinical development. In addition, we may incur significant milestone payment obligations as our product candidates progress through clinical trials towards commercialization. We expect that a substantial portion of our revenues for the next several years will be the result of amortization of payments already received and expected to be received from Genentech under our SGN-40 collaboration agreement. Our revenues for the foreseeable future will also depend on achieving development and clinical milestones under our existing collaboration and license agreements, particularly our SGN-40 collaboration with Genentech, as well as entering into new collaboration and license agreements. Our results of operations may vary substantially from year to year and from quarter to quarter and, as a result, we believe that period to period comparisons of our operating results may not be meaningful and you should not rely on them as indicative of our future performance.

Financial summary

To date, we have generated revenues principally from our collaboration and license agreements. These revenues include upfront technology access fees, milestone payments and reimbursement for support and materials supplied to our collaborators. For the six months ended June 30, 2008, revenues increased 72% to $17.1 million, compared to $9.9 million for the same period in 2007. Operating expenses increased 65% to $53.7 million, compared to $32.6 million for the same period in 2007. Our net loss for the six month period ended June 30, 2008 was $33.1 million, or $0.43 per share, compared to $19.4 million, or $0.35 per share, for the same period in 2007. As of June 30, 2008, we had $197.9 million in cash, cash equivalents and short-term and long-term investments and $124.1 million in total stockholders’ equity.

Genentech revenues increased 72% to $7.3 million in the second quarter of 2008 and increased 96% to $13.6 million for the first six months of 2008 compared to the comparable periods in 2007. These increases are primarily the result of revenues earned under the SGN-40 collaboration agreement with Genentech entered into in January 2007. Under the terms of this agreement, we perform research and development activities over the six-year development period of the agreement, the costs of which are reimbursed by Genentech. The $60 million upfront payment received in 2007 and all reimbursement and milestone payments received are deferred and recognized as revenue over the development period of the agreement using a time-based method. Genentech revenues also reflect the earned portion of payments received under our ADC collaboration agreement. Revenues earned under our collaboration with CuraGen increased to $1.1 million in the second quarter of 2008 and increased to $1.1 million for the first six months of 2008 from comparable periods in 2007. The increases in 2008 reflect a phase II clinical trial initiation milestone payment received from CuraGen in the second quarter. Revenues earned under our Bayer collaboration increased 362% to $887,000 in the second quarter and increased 50% to $918,000 for the first six months of 2008 from the comparable periods in 2007. These increases reflect the earned portion of a collaboration extension payment received from Bayer in May 2008. Revenues earned under our MedImmune collaboration increased 75% to $462,000 in the second quarter and increased 67% to $880,000 for the first six months of 2008 from the comparable periods in 2007. These increases reflect the earned portion of a $1.0 million fee paid by MedImmune to exercise an option to license a second antigen target in October 2007. Revenues earned under our Progenics collaboration decreased 8% to $252,000 in the second quarter and decreased 60% to $416,000 for the first six months of 2008 from the comparable periods in 2007 primarily due to a preclinical milestone earned during the first quarter of 2007.

We anticipate that revenues in 2008 will increase compared to 2007 primarily as a result of higher amounts of revenue earned under our SGN-40 collaboration with Genentech. In addition, we may receive progress-dependent milestones, annual maintenance fees and support fees as our collaborators advance their ADC product candidates through the development process. We expect that future revenues will vary from quarter to quarter depending on the progress made by our collaborators with their product candidates, the level of support we provide to our partners, the timing of milestones achieved and our ability to enter into additional collaboration agreements.

Research and development.

Research and development expenses increased 55% to $23.5 million in the second quarter of 2008 and increased 69% to $45.7 million in the first six months of 2008 from the comparable periods in 2007. Our research and development expenses are summarized as follows:

Research expenses remained relatively unchanged in the second quarter and increased 7% to $7.8 million in the first six months of 2008 from the comparable periods in 2007 primarily due to an increase in laboratory supply expenses and service costs. Development and contract manufacturing costs increased 40% to $7.4 million in the second quarter of 2008 and increased 53% to $15.5 million in the first six months of 2008 from the comparable periods in 2007. These increases reflect higher compensation and laboratory supply expenses related to increased staffing levels, the purchase of additional SGN-40 clinical supply from Abbott Laboratories during the first quarter of 2008 and increased SGN-35 manufacturing activities during the second quarter of 2008. Clinical costs increased 139% to $10.6 million in the second quarter of 2008 and increased 177% to $19.2 million in the first six months of 2008 from the comparable periods in 2007. These increases reflect expanded clinical trial activities for SGN-40, SGN-33 and SGN-35 as well as higher compensation costs related to increased staffing levels to support ongoing clinical trials. Share-based compensation expense remained relatively unchanged in the second quarter and increased 19% to $3.1 million in the first six months of 2008 from the comparable periods in 2007 reflecting the increase in the number of options outstanding associated with increased staffing levels and a higher per share value of options granted due to an increase in our common stock price. Share-based compensation expense in the second quarter of 2007 also includes a one-time severance-related amount.

Total research and development

   $ 23,499    $ 15,179    $ 45,651    $ 26,984    $ 233,185

Our third party costs for SGN-40 increased in both the three months and six months ended June 30, 2008 and reflect phase I and II clinical trial costs and the purchase of additional clinical material from Abbott Laboratories in the first quarter of 2008. We expect third party costs associated with SGN-40 to increase as we continue to enroll patients into multiple ongoing clinical trials and contract with Abbott Laboratories to manufacture additional drug for clinical supply. Under our SGN-40 collaboration agreement, Genentech reimburses us for development activities that we perform under the agreement. Expenses that we incur under the SGN-40 collaboration are included in our research and development expense, while reimbursements of those expenses by Genentech are recognized as revenue over the six year development period of the agreement. Our third party costs for SGN-33 increased in both the three months and six months ended June 30, 2008 and reflect costs associated with our phase I and II clinical studies. We expect our third party costs for SGN-33 to increase from amounts incurred in 2007 as clinical activities expand and as a manufacturing resupply campaign begins later in the year at Laureate Pharma. Our third party costs for SGN-35 increased in both the three months and six months ended June 30, 2008 and reflects our phase I clinical trial and contract manufacturing activities. We expect third party costs for SGN-35 to increase as we expand our clinical trials and initiate contract manufacturing activities for additional clinical supply. Our third party costs for SGN-70 decreased in both the three months and six months ended June 30, 2008 primarily due to completion of manufacturing activities conducted by Laureate Pharma during 2007 to perform scale-up and GMP manufacturing of drug product to support clinical trials. We expect third party costs for SGN-70 to continue to decrease from amounts incurred in 2007, reflecting lower manufacturing and preclinical development activities which will be partially offset by increasing clinical trial costs as clinical activities expand in 2008. SGN-75 third party costs in the three months and six months ended June 30, 2008 have increased over 2007 levels and reflect IND-enabling activities that are underway. We expect third party costs for SGN-75 to increase during 2008 compared to 2007 as IND-enabling and manufacturing activities continue to enable the initiation of clinical trials.

Our expenditures on current and future preclinical and clinical development programs are subject to numerous uncertainties in timing and cost to completion. In order to advance our product candidates toward commercialization, the product candidates are tested in numerous preclinical safety, toxicology and efficacy studies. We then conduct clinical trials for those product candidates that may take several years or more to complete. The length of time varies substantially based upon the type, complexity, novelty and intended use of a product candidate. The cost of clinical trials may vary significantly over the life of a project as a result of a variety of factors, including:

 

   

The number of patients who participate in the trials;

 

   

The length of time required to enroll trial participants;

 

   

The number of sites included in the trials;

 

   

The costs of producing supplies of the product candidates needed for clinical trials and regulatory submissions;

 

   

The safety and efficacy profile of the product candidate;

 

   

The use of clinical research organizations to assist with the management of the trials; and

 

   

The costs and timing of, and the ability to secure, regulatory approvals.

Furthermore, our strategy may include entering into collaborations with third parties to participate in the development and commercialization of some of our product candidates. In these situations, the preclinical development or clinical trial process for a product candidate and the estimated completion date may largely be under the control of that third party and not under our control. We cannot forecast with any degree of certainty which of our product candidates will be subject to future collaborations or how such arrangements would affect our development plans or capital requirements.

We anticipate that our research, development, contract manufacturing and clinical expenses will continue to grow in the foreseeable future as we expand our discovery and preclinical activities and advance new product candidates into clinical trials. These expenses will fluctuate based upon many factors including the degree of collaborative activities, timing of manufacturing campaigns, numbers of patients enrolled in our clinical trials and the outcome of each clinical trial event.

The risks and uncertainties associated with our research and development projects are discussed more fully in the section entitled “Risk Factors” that appears in our periodic reports filed with the SEC. As a result of the uncertainties discussed above, we are unable to determine with any degree of certainty the anticipated completion dates or completion costs of our research and development projects or when and to what extent we will receive cash inflows from the commercialization and sale of a product candidate.

General and administrative expenses increased 45% to $4.1 million in the second quarter of 2008 and increased 43% to $8.0 million for the first six months of 2008 from the comparable periods in 2007. General and administrative expenses, excluding share-based compensation expense, increased 27% to $3.0 million in the second quarter and 27% to $6.1 million for the first six months of 2008 from the comparable periods in 2007 primarily due to compensation expenses related to higher staffing levels. Share-based compensation expense increased 148% to $1.1 million during the second quarter of 2008 and 130% to $1.9 million for the first six months of 2008 from the comparable periods in 2007 reflecting additional stock option awards related to employee additions and higher per share value of options granted due to an increase in our common stock price. We anticipate that general and administrative expenses will continue to increase in 2008 as a result of increased costs related to adding personnel in support of the growth of our operations.

Investment income, net.

Investment income decreased 15% to $1.6 million in the second quarter of 2008 from the comparable period in 2007 primarily due to a decrease in the average yield on invested funds. Investment income increased 5% to $3.5 million in the first six months of 2008 from the comparable period in 2007 primarily due to higher levels of invested funds in 2008 following the completion of our common stock offering in January 2008 with net proceeds of $97.6 million.

Financing activities

   $ 99,042     $ 2,287  

We have financed the majority of our operations through the issuance of equity securities, supplemented by funding received from our collaboration and license agreements. To a lesser degree, we have also financed our operations through interest earned on cash, cash equivalents and investments. These financing sources have historically allowed us to maintain adequate levels of cash and investments.

Our combined cash, cash equivalents and investment securities increased to $197.9 million at June 30, 2008, compared to $129.6 million at December 31, 2007. This increase reflects cash provided by financing activities, which included net proceeds of $97.6 million from our common stock offering in January 2008. Our working capital was $97.5 million at June 30, 2008, compared to $90.0 million at December 31, 2007. We have structured our investment portfolio to align scheduled maturities of investment securities with our working capital needs. Our cash, cash equivalents and investments are held in a variety of interest-bearing instruments and subject to investment guidelines allowing for investments in U.S. government and agency securities, high-grade U.S. corporate bonds, taxable municipal bonds, mortgage-backed securities, auction-rate securities, commercial paper and money market accounts. We currently hold auction rate securities valued at $14.4 million that have failed at auction and are currently illiquid. Liquidity of these investments is subject to either a successful auction process, redemption of the investment, or a sale of the security in a secondary market. As of June 30, 2008, each of the failed auction-rate securities carries a “AAA” rating and continues to pay interest according to the stated terms. Based on our available cash, expected operating cash requirements, our belief that our holdings in auction rate securities can be liquidated in approximately one year through a successful auction or redemption at par and our ability and intent to hold such investments until liquidation, we believe that the current illiquidity of these investments is temporary. However, we will reassess this conclusion in future reporting periods based on several factors, including the continued failure of future auctions, failure of the investment to be redeemed, deterioration of the credit rating of the investment, market risk and other factors. Any such future reassessment that results in a conclusion that these investments are more than temporarily impaired would result in a write down in the fair value of these investments.

Included in net cash used in investing activities in 2008 are capital expenditures related to leasehold improvements, furniture and fixtures in support of our expansion into our new building which we began occupying in December 2007 and the purchase of laboratory equipment in support of our research and development activities. We expect that our 2008 capital expenditures will increase compared to 2007, reflecting additional leasehold improvements and equipment purchases planned in connection with the expansion of our facilities to accommodate our growth.

At our currently planned spending rate, we believe our current financial resources in addition to the expected fees and milestone payments earned under the SGN-40 collaboration agreement with Genentech and other existing collaboration and license agreements will be sufficient to fund our operations into 2010. However, changes in our spending rate may occur that would consume available capital resources sooner, such as increased manufacturing and clinical trial expenses preceding commercialization of a product candidate. We may seek additional funding through some or all of the following methods: corporate collaborations, licensing arrangements, public or private equity or debt financings. We do not know whether additional capital will be available when needed, or that, if available, we will obtain financing on terms favorable to our stockholders or us. If we are unable to raise additional funds should we need them, we may be required to delay, reduce or eliminate some of our development programs, which may adversely affect our business and operations.

Fair Value Inputs

We adopted SFAS No. 157, Fair Value Measurements on January 1, 2008. Fair value measurements reflect the assumptions that market participants would use in pricing an asset or liability based on the best information available. See Note 5 to the Condensed Consolidated Financial Statements.

We value our available-for-sale securities by using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities. The types of instruments valued based on quoted prices in markets that are not active, use broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include investment-grade corporate bonds, taxable municipal obligations, commercial paper and auction-rate securities. Management assesses the inputs of the pricing in order to categorize the financial instruments into the appropriate hierarchy levels prescribed by SFAS No. 157.

Commitments

Some of our manufacturing, license and collaboration agreements provide for periodic maintenance fees over specified time periods, as well as payments by us upon the achievement of development and regulatory milestones and the payment of royalties based on commercial product sales. We do not expect to pay any royalties on net sales of products under any of these agreements for at least the next several years. The amounts set forth below could be substantially higher if we make certain development achievements that require us to make milestone payments or if we receive regulatory approvals or achieve commercial sales and are required to pay royalties earlier than anticipated.

The minimum payments under manufacturing, license and collaboration agreements primarily represent contractual obligations related to performing scale-up and GMP manufacturing for monoclonal antibody and ADC products for use in our clinical trials, including obligations to Abbott Laboratories for manufacturing SGN-40 and the antibody component of SGN-35 and obligations to Laureate Pharma for manufacturing of SGN-33. The above table excludes royalties and payments of up to approximately $9.5 million in potential future milestone payments to third parties under manufacturing, license and collaboration agreements for our current development programs, which generally become due and payable only upon achievement of certain developmental, regulatory and/or commercial milestones. Because the achievement of these milestones is neither probable nor reasonably estimable with respect to timing, such contingent payments have not been included in the above table and will not be included until the event triggering such payment has occurred.

 

Item 3. Quantitative and Qualitative Disclosures About Market Risk

In accordance with our investment policy, we do not have any derivative financial instruments in our investment portfolio. We invest in high quality interest-bearing instruments, including U.S. government and agency securities, high-grade U.S. corporate bonds, taxable municipal bonds, adjustable mortgage-backed securities, auction-rate securities, commercial paper and money market accounts. Such securities are subject to interest rate risk and will rise and fall in value if market interest rates change; however, we do not expect any material loss from such interest rate changes.

 

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures. The Chief Executive Officer and the Chief Financial Officer have reviewed the Company’s disclosure controls and procedures prior to the filing of this quarterly report. Based on that review, they have concluded that, as of the end of the period covered by this quarterly report, these disclosure controls and procedures were, in design and operation, effective to assure that the required information has been properly recorded, processed, summarized and reported to those responsible in order that it may be included in this quarterly report.

(b) Changes in internal control over financial reporting. There have not been any changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2008 which have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
