NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2011

(In thousands of U.S. dollars except per share amounts or as otherwise disclosed)

(Unaudited)

(1) NATURE OF OPERATIONS AND BUSINESS RISKS

BioMarin Pharmaceutical Inc. (the Company or BioMarin), a Delaware corporation, develops and commercializes innovative biopharmaceuticals for serious diseases and medical conditions. BioMarin selects product candidates for diseases and conditions that represent a significant unmet medical need, have well-understood biology and provide an opportunity to be first-to-market or offer a significant benefit over existing products. The Company’s product portfolio is comprised of four approved products and multiple investigational product candidates. Approved products include Naglazyme (galsulfase), Kuvan (sapropterin dihydrochloride), Firdapse (amifampridine phosphate) and Aldurazyme (laronidase).

Through September 30, 2011, the Company had accumulated losses of approximately $398.4 million. Management believes that the Company’s cash, cash equivalents and short-term and long-term investments at September 30, 2011 will be sufficient to meet the Company’s obligations for the foreseeable future based on management’s current long-term business plans and assuming that the Company achieves its long-term goals. If the Company elects to increase its spending on development programs significantly above current long-term plans or enters into potential licenses and other acquisitions of complementary technologies, products or companies, the Company may need additional capital. The Company expects to continue to finance net future cash needs that exceed its operating activities primarily through its current cash, cash equivalents, short-term and long-term investments, and to the extent necessary, through proceeds from equity or debt financings, loans and collaborative agreements with corporate partners.

The Company is subject to a number of risks, including the financial performance of Naglazyme, Kuvan, Firdapse and Aldurazyme; the potential need for additional financings; its ability to successfully commercialize its product candidates, if approved; the uncertainty of the Company’s research and development efforts resulting in future successful commercial products; obtaining regulatory approval for new products; significant competition from larger organizations; reliance on the proprietary technology of others; dependence on key personnel; uncertain patent protection; dependence on corporate partners and collaborators; and possible restrictions on reimbursement from governmental agencies and healthcare organizations, as well as other changes in the health care industry.

(2) BASIS OF PRESENTATION

The accompanying Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for Quarterly Reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. The Condensed Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the fiscal year ended December 31, 2010 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 24, 2011.

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from those estimates. The Condensed Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair presentation of results for these interim periods. The results of operations for the three and nine months ended September 30, 2011 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2011.

The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing this Quarterly Report on Form 10-Q that would require recognition or disclosure in the Condensed Consolidated Financial Statements.

Significant Accounting Policies

There have been no material changes to the Company’s significant accounting policies during the nine months ended September 30, 2011, as compared to the significant accounting policies disclosed in Note 2 of the Company’s Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2010.

Reclassifications

Certain items in the Company’s prior year Condensed Consolidated Financial Statements have been reclassified to conform to the current presentation.

(3) RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, (ASU 2011-05). This newly issued accounting standard: (1) eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity; (2) requires the consecutive presentation of the statement of net income and other comprehensive income; and (3) requires an entity to present reclassification adjustments on the face of the financial statements from other comprehensive income to net income. The amendments to this ASU 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 nor do the amendments affect how earnings per share is calculated or presented. This ASU is required to be applied retrospectively and is effective for fiscal years and interim periods within those years beginning after December 15, 2011, which for the Company means January 1, 2012. As this accounting standard only requires enhanced disclosure, the adoption of this standard will not impact the Company’s financial position or results of operations.

In September 2011, the FASB issued ASU 2011-08, Goodwill and Other (Topic 350): Testing Goodwill for Inpairment, which simplifies goodwill impairment tests. The new guidance states that a qualitative assessment may be performed to determine whether further impairment testing is necessary. The Company will adopt this accounting standard upon its effective date for periods beginning on or after December 15, 2011. The adoption of this ASU is not expected to have a material impact on the Company’s financial position or results of operations.

On January 1, 2011, the Company adopted ASU Nos, 2010-13 and 2010-17, Multiple Deliverable Revenue Arrangements (ASU 2010-13) and Revenue Recognition – Milestone Method (ASU 2010-17). The adoption of these accounting principles did not have an impact on the Company’s consolidated financial statements.

Other than the accounting pronouncements disclosed above, there have been no new recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2011, as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, that have a material, or potentially material, impact on the Company’s Financial Statements.

(4) GOODWILL

Goodwill is tested for impairment on an annual basis and between annual tests if the Company becomes aware of any events occurring or changes in circumstances that would indicate a reduction in the fair value of the goodwill below its carrying amount.

The following table represents the changes in goodwill for the nine months ended September 30, 2011:

Balance at December 31, 2010	$	53,364
Reduction of goodwill related to acquisition of LEAD Therapeutics, Inc.		(309	)
Reduction of goodwill related to acquisition of ZyStor Therapeutics, Inc.		(1,512	)
Balance at September 30, 2011	$	51,543

During the third quarter of 2011, in connection with the acquisition of ZyStor Therapeutics, Inc., the Company recorded a reduction to goodwill of $1.5 million related to the retention of a portion of the $2.0 million of acquisition consideration withheld at closing to cover any indemnifiable claims made by the Company against the former stockholders of ZyStor Therapeutics, Inc.

During the first quarter of 2011, the Company recorded a reduction to goodwill of $0.3 million due to the adjustment of the original assumptions related to the contingent consideration payable for the acquisition of LEAD Therapeutics, Inc.

(5) SHORT-TERM AND LONG-TERM INVESTMENTS

All investments were classified as available-for-sale at September 30, 2011 and December 31, 2010. The principal amounts of short-term and long-term investments by contractual maturity are summarized in the tables below:

In August 2011, the Company acquired a bulk biologics manufacturing plant located in Shanbally, County Cork, Ireland (the Facility) for a total acquisition cost of $50.4 million, which includes $1.9 million of direct local transfer tax. The acquisition of the Facility was accounted for as a purchase of an asset, as it did not meet the definition of a business under ASC Topic 850, Business Combinations. Accordingly, the total purchase price was allocated to the identified assets based on their relative fair values on the date of acquisition.

(9) DERIVATIVE INSTRUMENTS AND HEDGING STRATEGIES

The Company uses hedging contracts to manage the risk of its overall exposure to fluctuations in foreign currency exchange rates. The Company considers all of its designated hedging instruments to be cash flow hedges.

Foreign Currency Exchange Rate Exposure

The Company uses forward foreign currency exchange contracts to hedge certain operational exposures resulting from changes in foreign currency exchange rates. Such exposures result from portions of the Company’s forecasted revenues being denominated in currencies other than the U.S. dollar, primarily the Euro.

The Company designates certain of these forward foreign currency exchange contracts as hedging instruments and enters into some forward foreign currency exchange contracts that are considered to be economic hedges that are not designated as hedging instruments. Whether designated or undesignated, these forward foreign currency exchange contracts protect against the reduction in value of forecasted foreign currency cash flows resulting from Naglazyme and Firdapse product revenues, Aldurazyme royalty revenues and net asset or liability positions designated in currencies other than the U.S. dollar. The fair values of forward foreign currency exchange contracts are estimated using current interest rates and take into consideration the current creditworthiness of the counterparties or the Company, as applicable. Details of the specific instruments used by the Company to hedge its exposure to foreign currency exchange rate fluctuations follow below. See Note 11 for additional discussion regarding the fair value of forward foreign currency exchange contracts.

At September 30, 2011, the Company had 142 forward foreign currency exchange contracts outstanding to sell a total of 80.9 million Euros with expiration dates ranging from October 31, 2011 through June 30, 2013. These hedges were entered into to protect against the fluctuations in Euro denominated Naglazyme, Firdapse and Aldurazyme revenues. The Company has formally designated these forward foreign currency exchange contracts as cash flow hedges and expects them to be highly effective within the meaning of FASB ASC Subtopic 815-30, Derivatives and Hedging-Cash Flow Hedges, in offsetting fluctuations in revenues denominated in Euros related to changes in the foreign currency exchange rates.

The Company also enters into forward foreign currency exchange contracts that are not designated as hedges for accounting purposes. The changes in fair value of these forward foreign currency exchange contracts are included as a part of selling, general and administrative expenses in the Condensed Consolidated Statements of Operations. At September 30, 2011, separate from the 142 contracts discussed above, the Company had one outstanding forward foreign currency exchange contract to sell 25.9 million Euros that was not designated as a hedge for accounting purposes.

The maximum length of time over which the Company is hedging its exposure to the reduction in value of forecasted foreign currency cash flows through forward foreign currency exchange contracts is through June 30, 2013. Over the next twelve months, the Company expects to reclassify $0.4 million from accumulated other comprehensive income to earnings as related forecasted revenue transactions occur.

(2) Effective portion classified as net product revenue

(3) Ineffective portion and amount excluded from effectiveness testing classified as selling, general and administrative expense

(4) Classified as selling, general and administrative expense

At September 30, 2011 and December 31, 2010, accumulated other comprehensive income/loss associated with foreign currency forward contracts qualifying for hedge accounting treatment was a gain of $1.6 million and a loss of $0.2 million, respectively.

The Company is exposed to counterparty credit risk on all of its derivative financial instruments. The Company has established and maintained strict counterparty credit guidelines and enters into hedges only with financial institutions that are investment grade or better to minimize the Company’s exposure to potential defaults. The Company does not require collateral to be pledged under these agreements.

(10) CONVERTIBLE DEBT

In April 2007, the Company sold approximately $324.9 million of senior subordinated convertible notes due 2017 (the 2017 Notes). The debt was issued at face value and bears interest at the rate of 1.875% per annum, payable semi-annually in cash. The debt is convertible, at the option of the holder, at any time prior to maturity or redemption, into shares of the Company’s common stock at a conversion price of approximately $20.36 per share, subject to adjustment in certain circumstances. The debt does not include a call provision and the Company is unable to unilaterally redeem the debt prior to maturity on April 23, 2017. The Company also must repay the debt if there is a qualifying change in control or termination of trading of its common stock.

In connection with the placement of the 2017 Notes, the Company paid approximately $8.5 million in offering costs, which have been deferred and are included in other assets. The deferred offering costs are being amortized as interest expense over the life of the debt, and in each of the three and nine months ended September 30, 2011 and 2010, the Company recognized amortization of expense of $0.2 million and $0.6 million, respectively.

In March 2006, the Company sold $172.5 million of senior subordinated convertible notes due 2013 (the 2013 Notes). The debt was issued at face value and bears interest at the rate of 2.5% per annum, payable semi-annually in cash. The debt is convertible, at the option of the holder, at any time prior to maturity or redemption, into shares of the Company’s common stock at a conversion price of approximately $16.58 per share, subject to adjustment in certain circumstances. The debt does not include a call provision and the Company is unable to unilaterally redeem the debt prior to maturity on March 29, 2013. The Company also must repay the debt if there is a qualifying change in control or termination of trading of its common stock.

In connection with the placement of the 2013 Notes, the Company paid approximately $5.5 million in offering costs, which have been deferred and are included in other assets. The deferred offering costs are being amortized as interest expense over the life of the debt. The Company recognized amortization expense of approximately $0.1 million and $0.2 million for the three and nine months ended September 30, 2011, respectively, compared to the three and nine months ended September 30, 2010 when amortization expense was $0.2 million and $0.6 million, respectively. The decrease in amortization expense for the three and nine months ended September 30, 2011, compared to the three and nine months ended September 30, 2010 was attributed to the conversion of $119.6 million in aggregate principal of the 2013 Notes in November 2010.

In September 2011, the Company entered into separate agreements with six of the existing holders of its 2013 Notes pursuant to which such holders converted $29.2 million in aggregate principal amount of the 2013 Notes into 1,760,178 shares of the Company’s common stock. In addition to issuing the requisite number of shares of the Company’s common stock pursuant to the 2013 Notes, the Company paid the holders future interest of approximately $1.1 million along with an aggregate of approximately $0.8 million related to varying cash premiums for agreeing to convert the 2013 Notes, which was recognized in total as debt conversion expense on the Company’s Consolidated Statement of Operations for the three and nine months ended September 30, 2011. Additionally, the Company reclassified $0.2 million of deferred offering costs to additional paid-in capital in connection with the conversion of the 2013 Notes.

In November 2010, the Company entered into separate agreements with nine of the existing holders of its 2013 Notes pursuant to which such holders converted $119.6 million in aggregate principal amount of the 2013 Notes into 7,213,379 shares of the Company’s common stock. In addition to issuing the requisite number of shares of the Company’s common stock pursuant to the 2013 Notes, the Company paid the holders future interest of approximately $7.2 million along with an aggregate of approximately $6.5 million related to varying cash premiums for agreeing to convert the 2013 Notes, which was recognized in total as debt conversion expense on the Company’s Consolidated Statement of Operations for the year ended December 31, 2010. Additionally, the Company reclassified $1.3 million of deferred offering costs to additional paid-in capital in connection with the conversion of the 2013 Notes.

Interest expense on the Company’s convertible debt for the three and nine months ended September 30, 2011 was $1.8 million and $5.5 million, respectively, compared to the three and nine months ended September 30, 2010 when interest expense related to the Company’s convertible debt was $2.6 million and $7.8 million, respectively. The decrease in interest expense related to the Company’s convertible debt in the three and nine months ended September 30, 2011, compared to the three and nine months ended September 30, 2010 was attributed to the conversion of $29.2 million and $119.6 million in aggregate principal of the 2013 Notes in September 2011 and November 2010, respectively.

(2) See Note 9 for further information regarding the Company’s derivative instruments.

(3) At September 30, 2011 and December 31, 2010, 93% and 94%, respectively, of the deferred compensation liability balance was included in other long-term liabilities and the remainder was included in accounts payable and accrued liabilities on the Condensed Company’s Consolidated Balance Sheets.

(4) At September 30, 2011 and December 31, 2010, 86% and 80%, respectively, of the contingent acquisition consideration payable was included in other long-term liabilities and 14% and 20%, respectively, was included in accounts payable and accrued liabilities.

(5) At September 30, 2011 the asset retirement obligation liability was included in other long-term liabilities.

The Company’s level 2 securities are valued using third-party pricing sources, which generally use interest rates and yield curves observable at commonly quoted intervals of similar assets as observable inputs for pricing. See Note 5 for further information regarding the Company’s financial instruments.

The Company’s level 3 liabilities are estimated using a probability-based income approach utilizing an appropriate discount rate. Subsequent changes in the fair value of the contingent acquisition consideration payable, resulting from the revision of key assumptions, will be recorded in intangible asset amortization and contingent consideration on the Company’s Condensed Consolidated Statements of Operations.

During the three and nine months ended September 30, 2011, the fair value of the contingent acquisition consideration payable decreased by $0.8 million and $5.7 million, respectively, due to changes in estimated probability and assumed timing of achievement of certain milestones and a $3.0 million development milestone payment to the former stockholders of Huxley Pharmaceuticals, Inc. Approximately $0.3 million of this change was recorded as a reduction to goodwill during the first quarter of 2011 due to an adjustment to the original assumptions related to the acquisition of LEAD Therapeutics, Inc. Key assumptions used by management to estimate the fair value of contingent acquisition consideration payable include assumed probabilities, timing of when a milestone may be attained and assumed discount periods and rates.

(12) STOCK-BASED COMPENSATION

The Company’s stock-based compensation plans include the 2006 Share Incentive Plan, as amended and restated on March 22, 2010 (2006 Share Incentive Plan) and the ESPP. These plans are administered by the Compensation Committee of the Company’s Board of Directors, which selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award. See Note 18 to the Company’s Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, for additional information related to these stock-based compensation plans.

Determining the Fair Value of Stock Options and Stock Purchase Rights

The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model and the assumptions noted in the tables below. The expected life of options is based on observed historical exercise patterns. Groups of employees that have similar historical exercise patterns were considered separately for valuation purposes, but none were identified that had distinctly different exercise patterns as of September 30, 2011. The expected volatility of stock options is based upon proportionate weightings of the historical volatility of the Company’s common stock and the implied volatility of traded options on the Company’s common stock for fiscal periods in which there is sufficient trading volume in options on the Company’s common stock. The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the option. The dividend yield reflects that the Company has not paid any cash dividends since inception and does not intend to pay any cash dividends in the foreseeable future. The assumptions used to estimate the per share fair value of stock options granted under the 2006 Share Incentive Plan were as follows:

The Company did not grant any new stock purchase rights under the ESPP during the three months ended September 30, 2011.

Restricted Stock Units with Service-Based Vesting Conditions

Restricted stock units (RSUs) are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. The Company expenses the cost of the RSUs, which is determined to be the fair market value of the shares of common stock underlying the RSUs at the date of grant, ratably over the period during which the vesting restrictions lapse. During the nine months ended September 30, 2011, the Company granted 0.3 million RSUs with a weighted average fair market value of $27.46 per share.

Restricted Stock Unit Awards with Performance and Market Vesting Conditions

On June 1, 2011, pursuant to the Board of Directors approval, the Company granted RSU awards under the 2006 Stock Incentive Plan to certain executive officers that provide for a base award of 875,000 RSUs (Base RSUs), with a grant date fair value of $32.61. The number of RSUs that could potentially vest from the Base RSUs granted is contingent upon achievement of specific performance goals and will be multiplied by the Total Shareholder Return (TSR) multiplier which could range from 75% to 125% to determine the number of earned RSU’s.

Stock-based compensation expense for this award will be recognized over the service period beginning in the period the Company determines the strategic performance goal or goals is probable of achievement. Accordingly because the Company’s management has not yet determined the goals are probable of achievement as of September 30, 2011, no compensation expense has been recognized for these awards for the three and nine months ended September 30,2011.

(15) REVENUE AND CREDIT CONCENTRATION

Net Product Revenue—The Company considers there to be revenue concentration risks for regions where net product revenue exceeds 10% of consolidated net product revenue. The concentration of the Company’s net product revenue within the regions below may have a material adverse effect on the Company’s revenue and results of operations if sales in the respective regions were to experience difficulties. The table below summarizes net product revenue concentrations based on patient location for Naglazyme, Kuvan and Firdapse and the location of Genzyme’s headquarters for Aldurazyme.

The accounts receivable balances at September 30, 2011 and December 31, 2010 were comprised of amounts due from customers for net product sales of Naglazyme, Kuvan and Firdapse and Aldurazyme product transfer and royalty revenues. On a consolidated basis, the three largest customers accounted for 43%, 13% and 12% of the September 30, 2011 accounts receivable balance, compared to December 31, 2010 when the two largest customers accounted for 47% and 17% of the accounts receivable balance. As of September 30, 2011 and December 31, 2010, accounts receivable for our largest customer balance included $28.4 million and $23.1 million, respectively, of unbilled accounts receivable related to net incremental Aldurazyme product transfers to Genzyme. The Company does not require collateral from its customers, but performs periodic credit evaluations of its customers’ financial condition and requires immediate payment in certain circumstances.

Factors that could cause or contribute to these differences include those discussed in “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the Securities and Exchange Commission (SEC) on February 24, 2011, as well as those discussed elsewhere in this Quarterly Report on Form 10-Q. You should carefully consider that information before you make an investment decision.

You should not place undue reliance on these statements, which speak only as of the date that they were made. These cautionary statements are based on the beliefs and assumptions of our management based on information currently available to management and should be considered in connection with any written or oral forward-looking statements that we may issue in the future. We do not undertake any obligation to release publicly any revisions to these forward-looking statements after completion of the filing of this Quarterly Report on Form 10-Q to reflect later events or circumstances or the occurrence of unanticipated events.

The following discussion of our financial condition and results of operations should be read in conjunction with our Condensed Consolidated Financial Statements and the related Notes thereto included elsewhere in this Quarterly Report on Form 10-Q.

Overview

We develop and commercialize innovative biopharmaceuticals for serious diseases and medical conditions. We select product candidates for diseases and conditions that represent a significant unmet medical need, have well-understood biology and provide an opportunity to be first-to-market or offer a significant benefit over existing products.

Key components of our results of operations include the following (in millions):

		00000000000			00000000000			00000000000			00000000000

Stock-based compensation expense		11.6			10.0			32.6			27.7

See “Results of Operations” below for a discussion of the detailed components and analysis of the amounts above.

Our product portfolio is comprised of four approved products and multiple investigational product candidates. Approved products include Naglazyme (galsulfase), Kuvan (sapropterin dihydrochloride), Firdapse (amifampridine phosphate) and Aldurazyme (laronidase).

Naglazyme, a recombinant form of N-acetylgalactosamine 4-sulfatase indicated for patients with mucopolysaccharidosis VI (MPS VI), received marketing approval in the U.S. in May 2005, in the EU in January 2006 and subsequently in other countries. Naglazyme net product revenues for the three and nine months ended September 30, 2011 totaled $55.9 million and $176.8 million, respectively, compared to $51.7 million and $147.5 million for the three and nine months ended September 30, 2010, respectively.

Kuvan was granted marketing approval for the treatment of phenylketonuria (PKU) in the U.S. and the EU in December 2007 and December 2008, respectively. Kuvan net product revenues for the three and nine months ended September 30, 2011 totaled $30.5 million and $86.0 million, respectively, compared to $26.2 million and $72.1 million for the three and nine months ended September 30, 2010, respectively.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – (Continued)

In December 2009, the European Medicines Agency (EMA) granted marketing approval for Firdapse, a proprietary form of 3-4-diaminopyridine (amifampridine phosphate), or 3-4-DAP, for the treatment of Lambert Eaton Myasthenic Syndrome (LEMS). We launched this product on a country by country basis in the EU beginning in April 2010. Firdapse net product revenues for the three and nine months ended September 30, 2011 totaled $3.5 million and $9.8 million, respectively, compared to $2.2 million and $3.4 million for the three and nine months ended September 30, 2010, respectively. We also continue to develop Firdapse for the possible treatment of LEMS in the U.S. and initiated a Phase 3 clinical trial in the second quarter of 2011.

Aldurazyme, which was developed in collaboration with Genzyme, was approved in 2003 for marketing in the U.S., the EU and subsequently other countries for patients with mucopolysaccharidosis I (MPS I). Aldurazyme net product revenues for the three and nine months ended September 30, 2011 totaled $23.0 million and $59.0 million, respectively, compared to $16.5 million and $48.2 million for the three and nine months ended September 30, 2010, respectively.

We are conducting clinical trials on several investigational product candidates including:

• GALNS, an enzyme replacement therapy for the treatment of MPS IV A (Morquio A Syndrome, a lysosomal storage disorder);

• PEG-PAL, an enzyme substitution therapy for the treatment of phenylketonuria or PKU;

• BMN-701, an enzyme replacement therapy for Pompe disease, a glycogen storage disorder; and

• BMN-673, an orally available poly-ADP ribose polymerase (PARP) inhibitor for the treatment of patients with cancer.

We are conducting preclinical development of several other product candidates for genetic and other metabolic diseases, including BMN-111, a peptide therapeutic for the treatment of achondroplasia.

Cost of sales includes raw materials, personnel and facility and other costs associated with manufacturing Naglazyme and Aldurazyme at our production facility in Novato, California. Cost of sales also includes third-party manufacturing costs for the production of Kuvan and Firdapse and third-party production costs related to vialing and packaging services for all products and cost of royalties payable to third parties for all products.

Research and development includes costs associated with the research and development of product candidates and post-marketing research commitments related to approved products. These costs primarily include preclinical and clinical studies, personnel and raw materials costs associated with manufacturing product candidates, quality control and assurance and regulatory costs.

Selling, general and administrative expense primarily includes expenses associated with the commercialization of approved products and general and administrative costs to support our operations. These expenses include: product marketing and sales operations personnel; corporate facility operating expenses; information technology expenses and depreciation; and core corporate support functions including human resources, finance and legal, and other external corporate costs such as insurance, audit and legal fees.

Intangible asset amortization and contingent consideration includes amortization expense related to our definite-lived intangible assets associated with marketing rights in the EU for Firdapse. Contingent consideration includes increases or decreases related to changes in the fair value of contingent acquisition consideration payable. Changes in fair value can result from changes in assumed probability adjustments, changes in assumed timing of when a milestone may be achieved and changes in assumed discount periods and rates.

Our cash, cash equivalents, short-term investments and long-term investments totaled $370.0 million as of September 30, 2011, compared to $402.3 million as of December 31, 2010. We have historically financed our operations primarily through the issuance of common stock and convertible debt and by relying on equipment and other commercial financing. During the fourth quarter of 2011, and for the foreseeable future, we will be highly dependent on our net product revenue to supplement our current liquidity and fund our operations. We may in the future elect to supplement this with further debt or equity offerings or commercial borrowing. Further, depending on market conditions, our financial position and performance and other factors, we may in the future choose to use a portion of our cash or cash equivalents to repurchase our convertible debt or other securities. See “Financial Position, Liquidity and Capital Resources” below for a further discussion of our liquidity and capital resources.

Critical Accounting Policies and Estimates

In preparing our Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the U.S. and pursuant to the rules and regulations promulgated by the SEC, we make assumptions, judgments and estimates that can have a significant impact on our net income/loss and affect the reported amounts of certain assets, liabilities, revenue and expenses, and related disclosures. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis, we evaluate our assumptions, judgments and estimates. We also discuss our critical accounting policies and estimates with the Audit Committee of our Board of Directors.

We believe that the assumptions, judgments and estimates involved in the accounting for business combinations, contingent acquisition consideration payable, income taxes, long-lived assets, revenue recognition and inventory have the greatest impact on our Condensed Consolidated Financial Statements, so we consider these to be our critical accounting policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results.

There have been no significant changes to our critical accounting policies and estimates during the nine months ended September 30, 2011, as compared to the critical accounting policies and estimates disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 24, 2011.

Recent Accounting Pronouncements

See Note 3 of our accompanying Condensed Consolidated Financial Statements for a full description of recent accounting pronouncements and our expectation of their impact, if any, on our results of operations and financial condition.

Results of Operations

Net Income (Loss)

Our net loss for the three and nine months ended September 30, 2011 was $17.7 million and $27.1 million, respectively, compared to net income of $217.3 million and $218.0 for the three and nine months ended September 30, 2010, respectively. The change in net income (loss) was primarily a result of the following (in millions):

		000000000000			000000000000
	Three Months			Nine Months
Net income for the period ended September 30, 2010	$	217.3		$	218.0
Absence of benefit from the reversal of deferred tax asset valuation allowance		(223.1	)		(223.1	)
Increased gross profit from product sales		11.9			47.7
Increased research and development expense		(19.2	)		(51.4	)
Increased selling, general and administrative expense		(6.5	)		(17.3	)
Decreased intangible asset amortization and contingent consideration		0.9			6.2
Debt conversion expense		(1.9	)		(1.9	)
(Increased) decreased income tax expense, excluding valuation allowance reversal		3.2			(3.8	)
Other individually insignificant fluctuations		(0.4	)		(1.5	)
Net loss for the period ended September 30, 2011	$	(17.7	)	$	(27.1	)

During the third quarter of 2010, we determined that it was more likely than not that the majority of our deferred tax assets, including net operating loss carryforwards (NOLs), would be realized, which resulted in the reversal of the deferred tax asset valuation allowance and an income tax benefit of $223.1 million. The increase in gross profit from product sales during the three and nine months ended September 30, 2011 as compared to the three and nine months ended September 30 , 2010 was primarily a result of additional Naglazyme patients initiating therapy, additional Kuvan patients initiating therapy in the U.S., and the commercial launch of Firdapse in Europe in April 2010. The increase in research and development expense was primarily attributed to increased development expenses for our GALNS, PEG-PAL, Firdapse, BMN-701 and BMN-673 programs. The increase in selling, general and administrative expense was primarily due to increased facility and employee related costs, continued international expansion of Naglazyme, U.S. commercialization activities related to Kuvan, the commercialization of Firdapse in Europe and bad debt expense. See below for additional information related to the primary net income (loss) fluctuations presented above, including details of our operating expense fluctuations.

Gross profit	$	15.7	$	12.4	$	3.3	$	42.1	$	38.1		$	4.0

Naglazyme net product revenues during the three and nine months ended September 30, 2011 totaled $55.9 million and $176.8 million, respectively, of which $48.2 million and $153.5 million, respectively, was earned from customers based outside the U.S. The impact of foreign currency exchange rates on Naglazyme sales denominated in currencies other than the U.S. dollar was negative by $0.5 million and positive $0.7 million for the three and nine months ended September 30, 2011, respectively. Gross profit from Naglazyme sales during the three and nine months ended September 30, 2011 was $46.4 million and $146.9 million, respectively, representing gross margins of 83% in both periods. Gross profit from Naglazyme sales in the three and nine months ended September 30, 2010 was $42.8 million and $120.9 million, respectively, representing gross margins of 83% and 82%, respectively. Naglazyme gross margins for the three and nine months ended September 30, 2011 were consistent with expectations and are not expected to fluctuate significantly in the future, however Naglazyme gross margins may increase as a result of manufacturing cost savings or other efficiencies.

Net product revenue for Kuvan during the three and nine months ended September 30, 2011 was $30.5 million and $86.0 million, respectively, compared to $26.2 million and $72.1 million for the three and nine months ended September 30, 2010, respectively. Gross profit from Kuvan during the three and nine months ended September 30, 2011 was approximately $25.5 million and $72.0 million, respectively, representing gross margins of approximately 83% and 84%, respectively, compared to the same periods in 2010 when gross profit totaled $21.6 million and $59.7 million, respectively, representing gross margins of 82% and 83%, respectively. The increase in gross margins was primarily attributed to price increases at the end of 2010. Cost of goods sold for the three and nine months ended September 30, 2011 and 2010 reflect royalties paid to third parties of approximately 9.8% and 11%, respectively. During the three and nine months ended September 30, 2011, we earned $0.4 million and $1.2 million, respectively, in royalties from Merck Serono on their net sales of $10.6 million and $29.4 million, respectively. Royalties earned from Merck Serono during the three and nine months ended September 30, 2010 were $0.3 million and $0.7 million, on their net sales of $6.3 million and $16.9 million, respectively. Kuvan gross margins for the three and nine months ended September 30, 2011 were consistent with expectations and are not expected to fluctuate significantly in the future.

We launched Firdapse in Europe on a country by country basis beginning in April 2010. Net product revenue for Firdapse during the three and nine months ended September 30, 2011 was $3.5 million and $9.8 million, respectively. Net product revenue for Firdapse during the three and nine months ended September 30, 2010 totaled $2.2 million and $3.4 million, respectively. Gross profit from Firdapse for the three and nine months ended September 30, 2011 was $2.9 million and $8.2 million, respectively, representing gross margins of 83% in both periods compared to the three and nine months ended September 30, 2010 when gross profit was $1.8 million and $2.7 million, respectively, representing gross margins of 80% and 79%, respectively.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – (Continued)

During the three and nine months ended September 30, 2011, Aldurazyme gross margins were 68% and 71%, respectively, compared to the three and nine months ended September 30, 2010 when gross margins were 75% and 79%, respectively. Aldurazyme gross margins reflect the profit earned on royalty revenue and net incremental product transfer revenue. The change in margins is attributed to the shift in revenue mix between royalty revenue and net product transfer revenues. Aldurazyme gross margins are expected to fluctuate depending on the mix of royalty revenue, from which we earn higher gross profit, and product transfer revenue, from which we earn lower gross profit.

Total cost of sales during the three and nine months ended September 30, 2011 was $22.4 million and $62.5 million, respectively, compared to $18.0 million and $49.8 million during the three and nine months ended September 30, 2010, respectively. The increase in cost of sales during the three and nine months ended September 30, 2011 compared to the same periods in 2010 was primarily attributed to the increase in product sales and the shift in Aldurazyme revenue mix.

Royalty and License Revenues

Royalty and license revenues were as follows (in millions):

		000000000		000000000		000000000			000000000		000000000		000000000
	Three Months Ended September 30,							Nine Months Ended September 30,
	2011		2010		Change			2011		2010		Change
Orapred product royalties	$	0	$	0.8	$	(0.8	)	$	0.5	$	2.2	$	(1.7	)
6R-BH4 royalty revenues		0.4		0.3		0.1			1.1		0.8		0.3
Total	$	0.4	$	1.1	$	(0.7	)	$	1.6	$	3.0	$	(1.4	)

Royalty and license revenues include Orapred product royalties, a product we acquired in 2004 and sublicensed in 2006, and 6R-BH4 royalty revenues for product sold in Japan. There is no cost of sales associated with the royalty and license revenues recorded during the periods and no related costs are expected in future periods.

We receive a royalty of 10% to 30% on net sales of Orapred from Shionogi Inc. (Shionogi) and a 15% royalty on net sales of 6R-BH4 from Daiichi Sankyo Co., LTD. Shionogi recorded no net sales during the three months ended September 30, 2011.

Research and Development Expense

Research and development expense increased to $58.6 million during the three months ended September 30, 2011, from $39.4 million during the three months ended September 30, 2010. Research and development expense increased to $156.5 million during the nine months ended September 30, 2011, from $105.1 million during the nine months ended September 30, 2010. The change in research and development expense was primarily a result of the following (in millions):

		000000000000			000000000000
	Three Months			Nine Months
Research and development expense for the period ended September 30, 2010	$	39.4		$	105.1
Increased GALNS for MPS IV A development expenses		5.4			22.9
Increased BMN-701 development expenses		4.3			10.1
Increased PEG-PAL development expenses		4.6			9.3
Decreased BMN-673 development expenses		(1.2	)		(1.0	)
(Decreased) increased ongoing development expenses related to commercial products		(0.8	)		2.1
Decreased BMN-195 for Duchenne muscular dystrophy development expenses		(0.5	)		(2.9	)
Increased stock-based compensation expense related to research and development		0.8			1.8
Increase in non-allocated research and development expenses and other net changes		6.6			9.1
Research and development expense for the period ended September 30, 2011	$	58.6		$	156.5

The increase in GALNS and PEG-PAL development expense was attributed to increased clinical trial activities related to these product candidates. The increase in BMN-673 development expense relates to clinical activities related to the product candidate acquired from LEAD Therapeutics, Inc. in February 2010. The increase in BMN-701 development expense relates to clinical activities related to the product candidate acquired from ZyStor Therapeutics, Inc. in October 2010. The increase in research and development expenses related to commercial products was primarily attributed to long-term Firdapse clinical activities related to post-approval regulatory commitments in the EU. The increase in stock-based compensation expense is a result of an increased number of options outstanding due to an increased number of employees. The increase in non-allocated research and development expense primarily includes increases in general research costs and research and development personnel costs that are not allocated to specific programs. We expect to continue incurring significant research and development expense for the foreseeable future due to long-term clinical activities related to post-approval regulatory commitments related to our approved products and spending on our GALNS, PEG-PAL, Firdapse, BMN-673 and BMN-701 programs and our other product candidates.

Selling, General and Administrative Expense

Selling, general and administrative expense increased to $44.9 million during the three months ended September 30, 2011, from $38.3 million during the three months ended September 30, 2010. Selling, general and administrative expense increased to $127.0 million during the nine months ended September 30, 2011, from $109.6 million during the nine months ended September 30, 2010. The change in selling, general and administrative expenses was primarily a result of the following (in millions):

	Three Months			Nine Months
Selling, general and administrative expense for period ended September 30, 2010	$	38.3		$	109.6
Increased sales and marketing expenses related to commercial products		0.3			5.3
Bad debt expense		0			1.0
Absence of transaction costs related to the acquisition of ZyStor		(1.8	)		(1.8	)
Increased stock-based compensation expense		0.6			2.1
Increased foreign exchange loss on unhedged transactions		2.9			2.3
Net increase in corporate overhead and other administrative expenses		4.6			8.5
Selling, general and administrative expense for the period ended September 30, 2011	$	44.9		$	127.0

We continue to incur sales and marketing expense for Naglazyme and Kuvan as a result of continued expansion of our international and U.S. activities, respectively, and spending related to the European commercialization of Firdapse, which launched in April 2010. The increase in corporate overhead and other administrative costs during the three and nine months ended September 30, 2011 was primarily comprised of increased employee related costs, legal costs, accounting costs and facility costs. We expect selling, general and administrative expenses to increase in future periods as a result of the international expansion of Naglazyme, the European commercialization activities for Firdapse and the U.S. commercialization activities for Kuvan.

Intangible Asset Amortization and Contingent Consideration Expense

Intangible asset amortization and contingent consideration expense is comprised of amortization of the European marketing rights for Firdapse and changes in the fair value of contingent acquisition consideration payable to former stockholders of our acquired businesses. Changes in the fair value of contingent acquisition consideration payable results from adjustments to the discount rates and updates to the assumed probability of achievement or timing of milestones. Intangible asset amortization and contingent consideration expense consisted of the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011			2010
Amortization of Firdapse European marketing rights	$	0.8	$	0.8	$	2.4		$	1.6
Changes in the fair value of contingent acquisition consideration payable		2.2		3.2		(2.4	)		4.6
Total intangible asset amortization and contingent consideration	$	3.0	$	4.0	$	0		$	6.2

The increase in the intangible asset amortization portion was attributed to the European commercial launch of Firdapse in April 2010 and the decrease in the contingent consideration amounts was due to changes in the fair value of contingent acquisition consideration payable resulting from changes in estimated probability and the estimated timing of when certain milestones may be achieved.

See Notes 5, 6 and 7 to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2010, for additional discussion.

Equity in the Loss of BioMarin/Genzyme LLC

Equity in the loss of BioMarin/Genzyme LLC includes our 50% share of the joint venture’s loss for the period. BioMarin/Genzyme LLC’s operations consist primarily of certain research and development activities and the intellectual property that are managed by the joint venture, with costs shared equally by BioMarin and Genzyme.

Equity in the loss of the joint venture totaled $0.6 million and $1.8 million for the three and nine months ended September 30, 2011, respectively, compared to $0.6 million and $2.2 million for the three and nine months ended September 30, 2010, respectively.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – (Continued)

Interest Income

We invest our cash, short-term and long-term investments in government and other high credit quality securities in order to limit default and market risk. Interest income totaled $0.7 million and $2.3 million, during the three and nine months ended September 30, 2011, respectively, compared to $1.0 million and $3.2 million during the three and nine months ended September 30, 2010, respectively. The reduced interest income during the three and nine months ended September 30, 2011 was due to decreased levels of cash and investments and lower market interest rates. We expect that interest income will continue to decline during the remainder of 2011 as compared to 2010 due to lower cash and investment balances and reduced interest yields.

Interest Expense

We incur interest expense on our convertible debt. Interest expense during the three and nine months ended September 30, 2011 was $2.4 million and $6.6 million, respectively, compared to $3.0 million and $8.1 million during the three and nine months ended September 30, 2010, respectively. The decrease in interest expense was attributed to the early conversion of $29.2 million and $119.6 million in aggregate principal of our 2013 Notes in September 2011 and November 2010, respectively. We expect interest expense for the fourth quarter of 2011 until the first quarter of 2013 to be $1.7 million per quarter based on the amount of our outstanding debt at September 30, 2011. See Note 10 to our accompanying Condensed Consolidated Financial Statements for additional discussion.

Provision for (Benefit from) Income Taxes

During the three and nine months ended September 30, 2011 we recognized a benefit from income taxes of $2.1 million and income tax expense of $6.6 million, respectively, compared to a benefit from income taxes of $222.0 million and $220.3 million during the three and nine months ended September 30, 2010, respectively. Our deferred tax assets increased due to a projected increase in research and development spend in 2011, which resulted in a lower 2011 forecasted tax rate and a benefit in the third quarter of 2011. The provision for income tax for the nine months ended September 30, 2011 consisted of foreign and state current and deferred tax expense related to the utilization of a portion of our federal net operating loss carryforwards. The benefit from income tax in the three and nine months ended September 30, 2010 consisted of foreign and state current tax expense and deferred tax benefit related to the release of $230.6 million of our valuation allowance in 2010 of which $223.1 million was released during the third quarter of 2010. See Note 22 to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2010, for additional discussion.

Financial Position, Liquidity and Capital Resources

We have historically financed our operations primarily through the issuance of common stock and convertible debt and by relying on equipment and other commercial financing. During the fourth quarter of 2011, and for the foreseeable future, we will be highly dependent on our net product revenue to supplement our current liquidity and fund our operations. We may in the future elect to supplement this with further debt or equity offerings or commercial borrowing. Further, depending on market conditions, our financial position and performance and other factors, we may in the future choose to use a portion of our cash or cash equivalents to repurchase our convertible debt or other securities.

Our financial condition as of September 30, 2011 and December 31, 2010 included the following (in millions):

		00000000		00000000		00000000
	September 30, 2011		December 31, 2010		Change
Cash and cash equivalents	$	71.3	$	88.1	$	(16.8	)
Short-term investments		153.1		186.0		(32.9	)
Long-term investments		145.6		128.2		17.4
Cash, cash equivalents and investments	$	370.0	$	402.3	$	(32.3	)
Current assets	$	487.0	$	504.3	$	(17.3	)
Current liabilities		83.3		83.8		(0.5	)
Working capital	$	403.7	$	420.5	$	(16.8	)
Convertible debt	$	348.3	$	377.5	$	(29.2	)

Management’s Discussion and Analysis of Financial Condition and Results of Operations – (Continued)

Our cash flows for each of the nine months ended September 30, 2011 and 2010 are summarized as follows (in millions):

		00000000			00000000			00000000
	2011			2010			Change
Cash and cash equivalents at the beginning of the year	$	88.1		$	167.2		$	(79.1	)
Net cash provided by operating activities		18.9			34.4			(15.5	)
Net cash used in investing activities		(54.6	)		(87.7	)		33.1
Net cash provided by financing activities		18.9			13.6			5.3
Cash and cash equivalents at the end of the year		71.3			127.5			(56.2	)
Short-term and long-term investments		298.7			313.4			(14.7	)
Cash, cash equivalents and investments	$	370.0		$	440.9		$	(70.9	)

Cash, cash equivalents and investments

Cash, cash equivalents and investments totaled $370.0 million at September 30, 2011, a decrease of $32.3 million from December 31, 2010. The decrease was primarily attributed to the $50.4 million of cash used in the purchase of the Shanbally facility and a $15.5 million decrease in net cash provided by operating activities, partially offset by proceeds from ESPP and stock option exercises of $23.4 million.

Working Capital

Working capital was $403.7 million at September 30, 2011, a decrease of $16.8 million from working capital at December 31, 2010. The decrease was primarily attributed to a decrease of $49.7 million in cash, cash equivalents and short-term investments, offset by increases in accounts receivable, inventory and other current asset of $20.5 million, $5.9 million and $6.1 million, respectively.

Cash Provided by Operating Activities

Cash provided by operating activities of $18.9 million for the nine months ended September 30, 2011 primarily related to net loss of $27.1 million, adjusted for non-cash items such as $26.5 million of depreciation and amortization expenses, $32.7 million of stock-based compensation expense, $6.8 million of deferred income taxes and $5.7 million of unrealized foreign exchange gains on forward foreign currency exchange contracts.

Cash provided by operating activities of $34.5 million for the nine months ended September 30, 2010 primarily relate to net income of $218.0 million, adjusted for non-cash items such as $223.1 million income tax benefit related to the reversal of a substantial portion of our deferred tax asset allowance, $19.8 million of depreciation and amortization expenses, $28.5 million of stock-based compensation expense, and $4.6 million increase in the fair value of contingent acquisition consideration payable.

Cash Used in Investing Activities

Net cash used by investing activities during the nine months ended September 30, 2011 was $54.6 million, compared to net cash used of $87.7 million during the nine months ended September 30, 2010. Our investing activities have consisted primarily of purchases and sales and maturities of investments, capital expenditures and cash paid for net assets acquired in business combinations. The increase in net cash used in investing activities for the nine months ended September 30, 2011 compared to the nine months ended September 30, 2010 was primarily due to increased capital expenditures of $25.8 million, lower spending on business acquisitions of $33.0 million and $24.9 million of net settlements of investment securities. The increase in capital expenditures was primarily driven by the purchase of the Shanbally facility in August 2011 for a total purchase price of $50.4 million.

Cash Provided by Financing Activities

Net cash provided by financing activities during the nine months ended September 30, 2011 was $18.9 million, compared to net cash provided by financing activities of $13.6 million during the nine months ended September 30, 2010. Our financing activities primarily include payments related to our contingent acquisition obligations, payments related to our convertible debt obligations and proceeds from the Employee Stock Purchase Plan (ESPP) and stock option exercises. The increase in net cash provided by financing activities during the nine months ended September 30, 2011, compared to the nine months ended September 30, 2010 was due to the decrease in payments of contingent acquisition consideration of $4.3 million, increased proceeds from ESPP and stock option exercises of $3.5 million offset by an increase in net payments on debt conversion of $2.2 million. See Note 10 of our Condensed Consolidated Financial Statements for additional discussion.

Other Information

In March 2006, we sold approximately $172.5 million of senior subordinated convertible notes due 2013 (the 2013 Notes). The debt was issued at face value and bears interest at the rate of 2.5% per annum, payable semi-annually in cash. In September 2011, $29.2 million in aggregate principal of the 2013 Notes were converted into approximately 1.8 million shares of the Company’s common stock. In November 2010, $119.6 million in aggregate principal of the 2013 Notes were converted into approximately 7.2 million shares of our common stock. There is no call provision included and we are unable to unilaterally redeem the remaining debt prior to maturity in 2013. The remaining debt is convertible, at the option of the holder, at any time prior to maturity, into shares of our common stock at a conversion price of approximately $16.58 per share, subject to adjustment in certain circumstances. However, we must repay the remaining debt prior to maturity if there is a qualifying change in control or termination of trading of our common stock.

In April 2007, we sold approximately $324.9 million of senior subordinated convertible notes due April 2017 (the 2017 Notes). The debt was issued at face value and bears interest at the rate of 1.875% per annum, payable semi-annually in cash. The debt is convertible, at the option of the holder, at any time prior to maturity, into shares of our common stock at a conversion price of approximately $20.36 per share, subject to adjustment in certain circumstances. Our debt does not contain a call provision and we are unable to unilaterally redeem the debt prior to maturity in 2017. We also must repay the debt if there is a qualifying change in control or termination of trading of our common stock. See Note 10 of our Condensed Consolidated Financial Statements for additional discussion. Our $348.3 million of total convertible debt as of September 30, 2011 will impact our liquidity due to the semi-annual cash interest payments and will impact our liquidity if the holders do not convert on or prior to the scheduled repayments of the debt.

We expect to fund our operations with our net product revenues from our commercial products; cash; cash equivalents; short-term and long-term investments supplemented by proceeds from equity or debt financings; and loans or collaborative agreements with

corporate partners, each to the extent necessary. We expect our current cash, cash equivalents and short-term and long-term investments will meet our operating and capital requirements for the foreseeable future based on our current long-term business plans and assuming that we are able to achieve our long-term goals. This expectation could also change depending on how much we elect to spend on our development programs and for potential licenses and acquisitions of complementary technologies, products and companies.

Funding Commitments

Our investment in our product development programs and continued development of our existing commercial products has a major impact on our operating performance. Our research and development expenses during the three and nine months ended September 30, 2011 and 2010 and during the period since inception (March 1997 for the portion not allocated to any major program) were as follows (in millions):

		000000		000000		000000		000000		000000
	Three Months Ended September 30,				Nine Months Ended September 30,				Since Program Inception

Totals	$	58.6	$	39.4	$	156.5	$	105.1	$	911.7

We cannot estimate with certainty the cost to complete any of our product development programs. Additionally, except as disclosed under “Overview” above, we cannot precisely estimate the time to complete any of our product development programs or when we expect to receive net cash inflows from any of our product development programs. Please see “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 24, 2011, for a discussion of the reasons we are unable to estimate such information, and in particular the following risk factors included in such Annual Report on Form 10-K:

• If we fail to maintain regulatory approval to commercially market and sell our drugs, or if approval is delayed, we will be unable to generate revenue from the sale of these products, our potential for generating positive cash flow will be diminished, and the capital necessary to fund our operations will be increased;

• To obtain regulatory approval to market our products, preclinical studies and costly and lengthy preclinical and clinical trials are required and the results of the studies and trials are highly uncertain;

• If we are unable to successfully develop manufacturing processes for our drug products to produce sufficient quantities at acceptable costs, we may be unable to meet demand for our products and lose potential revenue, have reduced margins or be forced to terminate a program;

• If we fail to compete successfully with respect to product sales, we may be unable to generate sufficient sales to recover our expenses related to the development of a product program or to justify continued marketing of a product and our revenue could be adversely affected; and

• If we do not achieve our projected development goals in the timeframes we announce and expect, the commercialization of our products may be delayed and the credibility of our management may be adversely affected and, as a result, our stock price may decline.

We may elect to increase our spending above our current long-term plans, which may increase our capital requirements. For instance, we may elect to increase our spending associated with the commercialization of our products; additional clinical trials; investments in the manufacturing of Naglazyme, Kuvan, Firdapse and Aldurazyme; preclinical studies and clinical trials for our other product candidates; potential licenses and other acquisitions of complementary technologies, products and companies; general corporate purposes; and working capital.

Our future capital requirements will depend on many factors, including, but not limited to:

• our ability to successfully market and sell Naglazyme and Kuvan;

• Genzyme’s ability to continue to successfully market and commercialize Aldurazyme;

• the progress, timing, scope and results of our preclinical studies and clinical trials;

• the time and cost necessary to obtain regulatory approvals and the costs of post-marketing studies which may be required by regulatory authorities;

30

Management’s Discussion and Analysis of Financial Condition and Results of Operations – (Continued)

• the time and cost necessary to develop commercial manufacturing processes, including quality systems and to build or acquire manufacturing capabilities;

• the time and cost necessary to respond to technological and market developments;

• any changes made to or new developments in our existing collaborative, licensing and other commercial relationships or any new collaborative, licensing and other commercial relationships that we may establish; and

• whether our convertible debt is converted to common stock in the future.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements other than our operating lease commitments totaling $23.5 million that are currently material or reasonably likely to be material to our consolidated financial position or results of operations.

We have obligations under various license, collaboration and acquisition agreements for contingent payments related to various development activities totaling approximately $359.2 million, which are due upon achievement of certain development, commercial and licensing milestones, and if they occur before certain dates in the future.

On September 14, 2011, we entered into agreements with three of our existing holders of our 2013 Notes, pursuant to which such holders have converted $9.6 million face amount of the 2013 Notes, in accordance with their terms, into 576,168 shares of our common stock. In addition to issuing the requisite number of shares of common stock required pursuant to the 2013 Notes, we also paid each of those holders varying cash premiums for agreeing to convert their 2013 Notes, which, in aggregate, totaled approximately $0.3 million. We also made a cash payment of approximately $0.1 million to the holders of accrued and future interest payments that will no longer be required. The issuance of our common stock upon conversion of the 2013 Notes was made in reliance on the exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 3(a)(9) thereof, as the conversion of the 2013 Notes into our common stock was made by us with our existing security holders exclusively in a series of privately negotiated transactions where no commission or other remuneration was paid.

Item 3. Defaults upon Senior Securities.

None.

Item 4. (Removed and Reserved).

Item 5. Other Information.

Inventory as of September 30, 2011 and December 31, 2010 includes $12.6 million and $14.8 million, respectively, of Naglazyme product manufactured in the Company's recently expanded production facility. The Company's expansion of its manufacturing facility, as for any new manufacturing facility or process, is required to be approved by the U.S. Food and Drug Administration (FDA) and similar ex-U.S. regulatory agencies before the product manufactured in this facility can be sold commercially. As of September 30, 2011, the expanded facility and new process have not been approved by the FDA or any other regulatory agency; however, the Company expects to receive FDA approval in the fourth quarter of 2011 or early 2012 and realize the costs of the remaining Naglazyme pre-qualification inventories through future sales.

Stock-Based Compensation

Stock-Based Compensation [Abstract]

Stock-Based Compensation

(12) STOCK-BASED COMPENSATION

The Company's stock-based compensation plans include the 2006 Share Incentive Plan, as amended and restated on March 22, 2010 (2006 Share Incentive Plan) and the ESPP. These plans are administered by the Compensation Committee of the Company's Board of Directors, which selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award. See Note 18 to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2010, for additional information related to these stock-based compensation plans.

Determining the Fair Value of Stock Options and Stock Purchase Rights

The fair value of each option award is estimated on the date of grant using the Black-Scholes valuation model and the assumptions noted in the tables below. The expected life of options is based on observed historical exercise patterns. Groups of employees that have similar historical exercise patterns were considered separately for valuation purposes, but none were identified that had distinctly different exercise patterns as of September 30, 2011. The expected volatility of stock options is based upon proportionate weightings of the historical volatility of the Company's common stock and the implied volatility of traded options on the Company's common stock for fiscal periods in which there is sufficient trading volume in options on the Company's common stock. The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the option. The dividend yield reflects that the Company has not paid any cash dividends since inception and does not intend to pay any cash dividends in the foreseeable future. The assumptions used to estimate the per share fair value of stock options granted under the 2006 Share Incentive Plan were as follows:

	0000000000	0000000000	0000000000	0000000000
	Three Months Ended September 30,		Nine Months Ended September 30,
Stock Option Valuation Assumptions	2011	2010	2011	2010
Expected volatility	47%	52%	47 – 50%	52%
Dividend yield	0.0%	0.0%	0.0%	0.0%
Expected life	6.4 years	6.2 years	6.3 – 6.4 years	6.2 years
Risk-free interest rate	1.3%	1.8%	1.3– 2.7%	1.8 – 2.7%
Weighted average fair value of common stock per share	$29.08	$21.70	$27.54	$21.39

During the nine months ended September 30, 2011, the Company granted 3.6 million options with a weighted average option value of $13.49 per option.

The Company did not grant any new stock purchase rights under the ESPP during the three months ended September 30, 2011.

Restricted Stock Units with Service-Based Vesting Conditions

Restricted stock units (RSUs) are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. The Company expenses the cost of the RSUs, which is determined to be the fair market value of the shares of common stock underlying the RSUs at the date of grant, ratably over the period during which the vesting restrictions lapse. During the nine months ended September 30, 2011, the Company granted 0.3 million RSUs with a weighted average fair market value of $27.46 per share.

Restricted Stock Unit Awards with Performance and Market Vesting Conditions

On June 1, 2011, pursuant to the Board of Directors approval, the Company granted RSU awards under the 2006 Stock Incentive Plan to certain executive officers that provide for a base award of 875,000 RSUs (Base RSUs), with a grant date fair value of $32.61. The number of RSUs that could potentially vest from the Base RSUs granted is contingent upon achievement of specific performance goals and will be multiplied by the Total Shareholder Return (TSR) multiplier which could range from 75% to 125% to determine the number of earned RSU's.

Stock-based compensation expense for this award will be recognized over the service period beginning in the period the Company determines the strategic performance goal or goals is probable of achievement. Accordingly because the Company's management has not yet determined the goals are probable of achievement as of September 30, 2011, no compensation expense has been recognized for these awards for the three and nine months ended September 30,2011.

Compensation expense included in the Company's Condensed Consolidated Statements of Operations for all stock-based compensation arrangements was as follows:

		000000000000		000000000000		000000000000		000000000000
	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Cost of sales	$	1,334	$	1,044	$	3,864	$	2,852
Research and development		4,372		3,621		12,070		10,244
Selling, general and administrative		5,912		5,292		16,673		14,578
Total stock-based compensation expense	$	11,618	$	9,957	$	32,607	$	27,674

During the nine months ended September 30, 2011 and 2010, stock-based compensation of $4.0 million and $3.7 million was capitalized into inventory, respectively. Capitalized stock-based compensation is recognized as cost of sales when the related product is sold.

Recent Accounting Pronouncements

(3) RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, (ASU 2011-05). This newly issued accounting standard: (1) eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity; (2) requires the consecutive presentation of the statement of net income and other comprehensive income; and (3) requires an entity to present reclassification adjustments on the face of the financial statements from other comprehensive income to net income. The amendments to this ASU 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 nor do the amendments affect how earnings per share is calculated or presented. This ASU is required to be applied retrospectively and is effective for fiscal years and interim periods within those years beginning after December 15, 2011, which for the Company means January 1, 2012. As this accounting standard only requires enhanced disclosure, the adoption of this standard will not impact the Company's financial position or results of operations.

In September 2011, the FASB issued ASU 2011-08, Goodwill and Other (Topic 350): Testing Goodwill for Inpairment, which simplifies goodwill impairment tests. The new guidance states that a qualitative assessment may be performed to determine whether further impairment testing is necessary. The Company will adopt this accounting standard upon its effective date for periods beginning on or after December 15, 2011. The adoption of this ASU is not expected to have a material impact on the Company's financial position or results of operations.

On January 1, 2011, the Company adopted ASU Nos, 2010-13 and 2010-17, Multiple Deliverable Revenue Arrangements (ASU 2010-13) and Revenue Recognition – Milestone Method (ASU 2010-17). The adoption of these accounting principles did not have an impact on the Company's consolidated financial statements.

Other than the accounting pronouncements disclosed above, there have been no new recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2011, as compared to the recent accounting pronouncements described in the Company's Annual Report on Form 10-K for the year ended December 31, 2010, that have a material, or potentially material, impact on the Company's Financial Statements.

Derivative Instruments And Hedging Strategies

(9) DERIVATIVE INSTRUMENTS AND HEDGING STRATEGIES

The Company uses hedging contracts to manage the risk of its overall exposure to fluctuations in foreign currency exchange rates. The Company considers all of its designated hedging instruments to be cash flow hedges.

Foreign Currency Exchange Rate Exposure

The Company uses forward foreign currency exchange contracts to hedge certain operational exposures resulting from changes in foreign currency exchange rates. Such exposures result from portions of the Company's forecasted revenues being denominated in currencies other than the U.S. dollar, primarily the Euro.

The Company designates certain of these forward foreign currency exchange contracts as hedging instruments and enters into some forward foreign currency exchange contracts that are considered to be economic hedges that are not designated as hedging instruments. Whether designated or undesignated, these forward foreign currency exchange contracts protect against the reduction in value of forecasted foreign currency cash flows resulting from Naglazyme and Firdapse product revenues, Aldurazyme royalty revenues and net asset or liability positions designated in currencies other than the U.S. dollar. The fair values of forward foreign currency exchange contracts are estimated using current interest rates and take into consideration the current creditworthiness of the counterparties or the Company, as applicable. Details of the specific instruments used by the Company to hedge its exposure to foreign currency exchange rate fluctuations follow below. See Note 11 for additional discussion regarding the fair value of forward foreign currency exchange contracts.

At September 30, 2011, the Company had 142 forward foreign currency exchange contracts outstanding to sell a total of 80.9 million Euros with expiration dates ranging from October 31, 2011 through June 30, 2013. These hedges were entered into to protect against the fluctuations in Euro denominated Naglazyme, Firdapse and Aldurazyme revenues. The Company has formally designated these forward foreign currency exchange contracts as cash flow hedges and expects them to be highly effective within the meaning of FASB ASC Subtopic 815-30, Derivatives and Hedging-Cash Flow Hedges, in offsetting fluctuations in revenues denominated in Euros related to changes in the foreign currency exchange rates.

The Company also enters into forward foreign currency exchange contracts that are not designated as hedges for accounting purposes. The changes in fair value of these forward foreign currency exchange contracts are included as a part of selling, general and administrative expenses in the Condensed Consolidated Statements of Operations. At September 30, 2011, separate from the 142 contracts discussed above, the Company had one outstanding forward foreign currency exchange contract to sell 25.9 million Euros that was not designated as a hedge for accounting purposes.

The maximum length of time over which the Company is hedging its exposure to the reduction in value of forecasted foreign currency cash flows through forward foreign currency exchange contracts is through June 30, 2013. Over the next twelve months, the Company expects to reclassify $0.4 million from accumulated other comprehensive income to earnings as related forecasted revenue transactions occur.

At September 30, 2011 and December 31, 2010, the fair value carrying amounts of the Company's derivative instruments were as follows:

	Asset Derivatives September  30, 2011				Liability  Derivatives September 30, 2011

The effect of the Company's derivative instruments on the Condensed Consolidated Financial Statements for the three and nine months ended September 30, 2011 and 2010 was as follows:

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

(2) Effective portion classified as net product revenue

(3) Ineffective portion and amount excluded from effectiveness testing classified as selling, general and administrative expense

(4) Classified as selling, general and administrative expense

At September 30, 2011 and December 31, 2010, accumulated other comprehensive income/loss associated with foreign currency forward contracts qualifying for hedge accounting treatment was a gain of $1.6 million and a loss of $0.2 million, respectively.

The Company is exposed to counterparty credit risk on all of its derivative financial instruments. The Company has established and maintained strict counterparty credit guidelines and enters into hedges only with financial institutions that are investment grade or better to minimize the Company's exposure to potential defaults. The Company does not require collateral to be pledged under these agreements.

Comprehensive Income (Loss) And Accumulated Other Comprehensive Income (Loss)

(14) COMPREHENSIVE INCOME (LOSS) AND ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss) includes net income (loss) and certain changes in stockholders' equity that are excluded from net income (loss), such as changes in unrealized gains and losses on the Company's available-for-sale securities, unrealized gains and losses on foreign currency hedges and changes in the Company's cumulative foreign currency translation account. The provision for income taxes related to the items included in other comprehensive income (loss), assuming they were recognized in income, would be approximately $0.4 million and $0.4 million at September 30, 2011 and December 31, 2010, respectively.

During the three and nine months ended September 30, 2011, total comprehensive loss was approximately $10.4 million and $26.0 million, respectively, compared to the three and nine months ended September 30, 2010 when total comprehensive income was $205.5 million and $215.5 million, respectively. The fluctuation in accumulated other comprehensive income (loss) was comprised of the following:

Convertible Debt [Abstract]

Convertible Debt

(10) CONVERTIBLE DEBT

In April 2007, the Company sold approximately $324.9 million of senior subordinated convertible notes due 2017 (the 2017 Notes). The debt was issued at face value and bears interest at the rate of 1.875% per annum, payable semi-annually in cash. The debt is convertible, at the option of the holder, at any time prior to maturity or redemption, into shares of the Company's common stock at a conversion price of approximately $20.36 per share, subject to adjustment in certain circumstances. The debt does not include a call provision and the Company is unable to unilaterally redeem the debt prior to maturity on April 23, 2017. The Company also must repay the debt if there is a qualifying change in control or termination of trading of its common stock.

In connection with the placement of the 2017 Notes, the Company paid approximately $8.5 million in offering costs, which have been deferred and are included in other assets. The deferred offering costs are being amortized as interest expense over the life of the debt, and in each of the three and nine months ended September 30, 2011 and 2010, the Company recognized amortization of expense of $0.2 million and $0.6 million, respectively.

In March 2006, the Company sold $172.5 million of senior subordinated convertible notes due 2013 (the 2013 Notes). The debt was issued at face value and bears interest at the rate of 2.5% per annum, payable semi-annually in cash. The debt is convertible, at the option of the holder, at any time prior to maturity or redemption, into shares of the Company's common stock at a conversion price of approximately $16.58 per share, subject to adjustment in certain circumstances. The debt does not include a call provision and the Company is unable to unilaterally redeem the debt prior to maturity on March 29, 2013. The Company also must repay the debt if there is a qualifying change in control or termination of trading of its common stock.

In connection with the placement of the 2013 Notes, the Company paid approximately $5.5 million in offering costs, which have been deferred and are included in other assets. The deferred offering costs are being amortized as interest expense over the life of the debt. The Company recognized amortization expense of approximately $0.1 million and $0.2 million for the three and nine months ended September 30, 2011, respectively, compared to the three and nine months ended September 30, 2010 when amortization expense was $0.2 million and $0.6 million, respectively. The decrease in amortization expense for the three and nine months ended September 30, 2011, compared to the three and nine months ended September 30, 2010 was attributed to the conversion of $119.6 million in aggregate principal of the 2013 Notes in November 2010.

In September 2011, the Company entered into separate agreements with six of the existing holders of its 2013 Notes pursuant to which such holders converted $29.2 million in aggregate principal amount of the 2013 Notes into 1,760,178 shares of the Company's common stock. In addition to issuing the requisite number of shares of the Company's common stock pursuant to the 2013 Notes, the Company paid the holders future interest of approximately $1.1 million along with an aggregate of approximately $0.8 million related to varying cash premiums for agreeing to convert the 2013 Notes, which was recognized in total as debt conversion expense on the Company's Consolidated Statement of Operations for the three and nine months ended September 30, 2011. Additionally, the Company reclassified $0.2 million of deferred offering costs to additional paid-in capital in connection with the conversion of the 2013 Notes.

In November 2010, the Company entered into separate agreements with nine of the existing holders of its 2013 Notes pursuant to which such holders converted $119.6 million in aggregate principal amount of the 2013 Notes into 7,213,379 shares of the Company's common stock. In addition to issuing the requisite number of shares of the Company's common stock pursuant to the 2013 Notes, the Company paid the holders future interest of approximately $7.2 million along with an aggregate of approximately $6.5 million related to varying cash premiums for agreeing to convert the 2013 Notes, which was recognized in total as debt conversion expense on the Company's Consolidated Statement of Operations for the year ended December 31, 2010. Additionally, the Company reclassified $1.3 million of deferred offering costs to additional paid-in capital in connection with the conversion of the 2013 Notes.

Interest expense on the Company's convertible debt for the three and nine months ended September 30, 2011 was $1.8 million and $5.5 million, respectively, compared to the three and nine months ended September 30, 2010 when interest expense related to the Company's convertible debt was $2.6 million and $7.8 million, respectively. The decrease in interest expense related to the Company's convertible debt in the three and nine months ended September 30, 2011, compared to the three and nine months ended September 30, 2010 was attributed to the conversion of $29.2 million and $119.6 million in aggregate principal of the 2013 Notes in September 2011 and November 2010, respectively.

Nature Of Operations And Business Risks

(1) NATURE OF OPERATIONS AND BUSINESS RISKS

BioMarin Pharmaceutical Inc. (the Company or BioMarin), a Delaware corporation, develops and commercializes innovative biopharmaceuticals for serious diseases and medical conditions. BioMarin selects product candidates for diseases and conditions that represent a significant unmet medical need, have well-understood biology and provide an opportunity to be first-to-market or offer a significant benefit over existing products. The Company's product portfolio is comprised of four approved products and multiple investigational product candidates. Approved products include Naglazyme (galsulfase), Kuvan (sapropterin dihydrochloride), Firdapse (amifampridine phosphate) and Aldurazyme (laronidase).

Through September 30, 2011, the Company had accumulated losses of approximately $398.4 million. Management believes that the Company's cash, cash equivalents and short-term and long-term investments at September 30, 2011 will be sufficient to meet the Company's obligations for the foreseeable future based on management's current long-term business plans and assuming that the Company achieves its long-term goals. If the Company elects to increase its spending on development programs significantly above current long-term plans or enters into potential licenses and other acquisitions of complementary technologies, products or companies, the Company may need additional capital. The Company expects to continue to finance net future cash needs that exceed its operating activities primarily through its current cash, cash equivalents, short-term and long-term investments, and to the extent necessary, through proceeds from equity or debt financings, loans and collaborative agreements with corporate partners.

The Company is subject to a number of risks, including the financial performance of Naglazyme, Kuvan, Firdapse and Aldurazyme; the potential need for additional financings; its ability to successfully commercialize its product candidates, if approved; the uncertainty of the Company's research and development efforts resulting in future successful commercial products; obtaining regulatory approval for new products; significant competition from larger organizations; reliance on the proprietary technology of others; dependence on key personnel; uncertain patent protection; dependence on corporate partners and collaborators; and possible restrictions on reimbursement from governmental agencies and healthcare organizations, as well as other changes in the health care industry.

Goodwill [Abstract]

Goodwill

(4) GOODWILL

Goodwill is tested for impairment on an annual basis and between annual tests if the Company becomes aware of any events occurring or changes in circumstances that would indicate a reduction in the fair value of the goodwill below its carrying amount.

The following table represents the changes in goodwill for the nine months ended September 30, 2011:

Balance at December 31, 2010	$	53,364
Reduction of goodwill related to acquisition of LEAD Therapeutics, Inc.		(309	)
Reduction of goodwill related to acquisition of ZyStor Therapeutics, Inc.		(1,512	)
Balance at September 30, 2011	$	51,543

During the third quarter of 2011, in connection with the acquisition of ZyStor Therapeutics, Inc., the Company recorded a reduction to goodwill of $1.5 million related to the retention of a portion of the $2.0 million of acquisition consideration withheld at closing to cover any indemnifiable claims made by the Company against the former stockholders of ZyStor Therapeutics, Inc.

During the first quarter of 2011, the Company recorded a reduction to goodwill of $0.3 million due to the adjustment of the original assumptions related to the contingent consideration payable for the acquisition of LEAD Therapeutics, Inc.

Less: Accumulated depreciation		(107,857	)		(85,075	)
Total property, plant and equipment, net	$	266,190		$	221,866

In August 2011, the Company acquired a bulk biologics manufacturing plant located in Shanbally, County Cork, Ireland (the Facility) for a total acquisition cost of $50.4 million, which includes $1.9 million of direct local transfer tax. The acquisition of the Facility was accounted for as a purchase of an asset, as it did not meet the definition of a business under ASC Topic 850, Business Combinations. Accordingly, the total purchase price was allocated to the identified assets based on their relative fair values on the date of acquisition.

The allocation of the purchase price was as follows:

		00000000000000
	Acquisition Date Relative Fair Value
Manufacturing and laboratory equipment	$	23,248
Furniture and fixtures		912
Computer hardware and software		328
Building and improvements		24,057
Land		1,127
Consumable supplies capitalized in other assets		766
Total purchase price		50,438
Less consumables		(766	)
Net property, plant and equipment acquired	$	49,672

As of September 30, 2011, the fair value of the acquired assets is included in the construction in-process balance as the assets have not been placed into service.

Depreciation expense during the three and nine months ended September 30, 2011 was $8.1 million and $22.8 million, respectively, of which $2.1 million and $4.1 million was capitalized into inventory, respectively. Depreciation expense during the three and nine months ended September 30, 2010 was $6.3 million and $16.4 million, respectively, of which $1.5 million and $3.2 million was capitalized into inventory, respectively.

Capitalized interest related to the Company's property, plant and equipment purchases for both the three and nine months ended September 30, 2011 was insignificant, compared to the three and nine months ended September 30, 2010 when capitalized interest was $0 and $0.7 million, respectively.

(2) BASIS OF PRESENTATION

The accompanying Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for Quarterly Reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. The Condensed Consolidated Financial Statements should therefore be read in conjunction with the Consolidated Financial Statements and Notes thereto for the fiscal year ended December 31, 2010 included in the Company's Annual Report on Form 10-K filed with the SEC on February 24, 2011.

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying disclosures. Although these estimates are based on management's best knowledge of current events and actions that the Company may undertake in the future, actual results may be different from those estimates. The Condensed Consolidated Financial Statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for a fair presentation of results for these interim periods. The results of operations for the three and nine months ended September 30, 2011 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2011.

The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing this Quarterly Report on Form 10-Q that would require recognition or disclosure in the Condensed Consolidated Financial Statements.

Significant Accounting Policies

There have been no material changes to the Company's significant accounting policies during the nine months ended September 30, 2011, as compared to the significant accounting policies disclosed in Note 2 of the Company's Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2010.

(3) At September 30, 2011 and December 31, 2010, 93% and 94%, respectively, of the deferred compensation liability balance was included in other long-term liabilities and the remainder was included in accounts payable and accrued liabilities on the Condensed Company's Consolidated Balance Sheets.

(5) At September 30, 2011 the asset retirement obligation liability was included in other long-term liabilities.

The Company's level 2 securities are valued using third-party pricing sources, which generally use interest rates and yield curves observable at commonly quoted intervals of similar assets as observable inputs for pricing. See Note 5 for further information regarding the Company's financial instruments.

The Company's level 3 liabilities are estimated using a probability-based income approach utilizing an appropriate discount rate. Subsequent changes in the fair value of the contingent acquisition consideration payable, resulting from the revision of key assumptions, will be recorded in intangible asset amortization and contingent consideration on the Company's Condensed Consolidated Statements of Operations.

During the three and nine months ended September 30, 2011, the fair value of the contingent acquisition consideration payable decreased by $0.8 million and $5.7 million, respectively, due to changes in estimated probability and assumed timing of achievement of certain milestones and a $3.0 million development milestone payment to the former stockholders of Huxley Pharmaceuticals, Inc. Approximately $0.3 million of this change was recorded as a reduction to goodwill during the first quarter of 2011 due to an adjustment to the original assumptions related to the acquisition of LEAD Therapeutics, Inc. Key assumptions used by management to estimate the fair value of contingent acquisition consideration payable include assumed probabilities, timing of when a milestone may be attained and assumed discount periods and rates.

See Notes 5, 6 and 7, to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2010 for additional discussion related to business acquisitions and contingent acquisition consideration payable.

(15) REVENUE AND CREDIT CONCENTRATION

Net Product Revenue—The Company considers there to be revenue concentration risks for regions where net product revenue exceeds 10% of consolidated net product revenue. The concentration of the Company's net product revenue within the regions below may have a material adverse effect on the Company's revenue and results of operations if sales in the respective regions were to experience difficulties. The table below summarizes net product revenue concentrations based on patient location for Naglazyme, Kuvan and Firdapse and the location of Genzyme's headquarters for Aldurazyme.

The accounts receivable balances at September 30, 2011 and December 31, 2010 were comprised of amounts due from customers for net product sales of Naglazyme, Kuvan and Firdapse and Aldurazyme product transfer and royalty revenues. On a consolidated basis, the three largest customers accounted for 43%, 13% and 12% of the September 30, 2011 accounts receivable balance, compared to December 31, 2010 when the two largest customers accounted for 47% and 17% of the accounts receivable balance. As of September 30, 2011 and December 31, 2010, accounts receivable for our largest customer balance included $28.4 million and $23.1 million, respectively, of unbilled accounts receivable related to net incremental Aldurazyme product transfers to Genzyme. The Company does not require collateral from its customers, but performs periodic credit evaluations of its customers' financial condition and requires immediate payment in certain circumstances.
