The Company and Summary of Significant Accounting Policies

1. The Company and Summary of Significant Accounting Policies

Jazz Pharmaceuticals Public Limited Company, or Jazz Pharmaceuticals plc, a public limited company formed under the laws of Ireland, is a specialty biopharmaceutical company dedicated to improving patients’ lives through the identification, development and commercialization of pharmaceutical products that address unmet medical needs in focused therapeutic areas.

On January 18, 2012, the businesses of Jazz Pharmaceuticals, Inc. and Azur Pharma Public Limited Company, or Azur Pharma, were combined in a merger transaction, or the Azur Merger, accounted for as a reverse acquisition under the acquisition method of accounting for business combinations, with Jazz Pharmaceuticals, Inc. treated as the acquiring company for accounting purposes. As part of the Azur Merger, a wholly-owned subsidiary of Azur Pharma merged with and into Jazz Pharmaceuticals, Inc., with Jazz Pharmaceuticals, Inc. surviving the Azur Merger as a wholly-owned subsidiary of Jazz Pharmaceuticals plc. Prior to the Azur Merger, Azur Pharma changed its name to Jazz Pharmaceuticals plc. Upon the consummation of the Azur Merger, the historical financial statements of Jazz Pharmaceuticals, Inc. became our historical financial statements. Accordingly, the historical financial statements of Jazz Pharmaceuticals, Inc. only are included in the comparative prior periods. For additional information regarding the Azur Merger see Note 2.

On June 12, 2012, we completed the acquisition of EUSA Pharma Inc., or EUSA Pharma, which we refer to as the EUSA Acquisition. As part of the EUSA Acquisition, an indirect wholly-owned subsidiary of Jazz Pharmaceuticals plc merged with and into EUSA Pharma, with EUSA Pharma continuing as the surviving corporation and as an indirect wholly-owned subsidiary of Jazz Pharmaceuticals plc. For additional information regarding the EUSA Acquisition see Note 2.

Unless otherwise indicated or the context otherwise requires, references to “Jazz Pharmaceuticals,” “the registrant,” “we,” “us,” and “our” refer to Jazz Pharmaceuticals plc and its consolidated subsidiaries, including its predecessor, Jazz Pharmaceuticals, Inc., except that all such references prior the effective time of the Azur Merger on January 18, 2012 are references to Jazz Pharmaceuticals, Inc. and its consolidated subsidiaries. All references to “Azur Pharma” are references to Jazz Pharmaceuticals plc (f/k/a Azur Pharma Public Limited Company) and its consolidated subsidiaries prior to the effective time of the Azur Merger on January 18, 2012. The disclosures in this report relating to the pre-Azur Merger business of Jazz Pharmaceuticals plc, unless noted as being the business of Azur Pharma prior to the Azur Merger, pertain to the business of Jazz Pharmaceuticals, Inc. prior to the Azur Merger.

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared following the requirements of the Securities and Exchange Commission, or SEC, for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by U.S. generally accepted accounting principles, or GAAP, can be condensed or omitted. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the annual consolidated financial statements and accompanying notes of Jazz Pharmaceuticals, Inc. included in the Annual Report on Form 10-K for the year ended December 31, 2011 that we filed on behalf of and as successor to Jazz Pharmaceuticals, Inc. Because the Azur Merger was consummated after December 31, 2011, we also filed a separate Annual Report on Form 10-K covering the last full fiscal year of Azur Pharma that includes the annual consolidated financial statements and accompanying notes of Azur Pharma (Commission File Number 333-177528). The results of operations of the acquired Azur Pharma and EUSA Pharma businesses, along with the estimated fair values of the assets acquired and liabilities assumed in each transaction, have been included in our condensed consolidated financial statements since the effective dates of the Azur Merger and the EUSA Acquisition, respectively.

In the opinion of management, these condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements of Jazz Pharmaceuticals, Inc. and include all adjustments, consisting only of normal recurring adjustments, considered necessary for the fair presentation of our financial position and operating results. The results for the three and six months ended June 30, 2012 are not necessarily indicative of the results to be expected for the year ending December 31, 2012, for any other interim period or for any future period.

The consolidated financial statements include the accounts of Jazz Pharmaceuticals plc and our wholly-owned subsidiaries and intercompany transactions and balances have been eliminated.

Significant Risks and Uncertainties

Our financial results are significantly influenced by sales of Xyrem, and maintaining and increasing sales of Xyrem is subject to a number of risks and uncertainties, including the potential introduction of generic competition, and changed or increased regulatory restrictions. During 2010, an abbreviated new drug application, or ANDA, was filed with the United States Food and Drug Administration, or FDA, by a third party seeking to market a generic form of Xyrem. We have sued that third party for infringement of our patents, and the litigation is ongoing. If an ANDA for Xyrem is approved and a generic version of Xyrem is introduced, our sales of Xyrem would be adversely affected. In addition, we are continuing our ongoing work with the FDA on both changes to our Xyrem product label and our risk management and distribution system for Xyrem. The FDA may take, or require us to take, actions that could make it more difficult or expensive for us to distribute Xyrem, make competition easier and/or negatively affect the commercial success of Xyrem.

In addition to risks related specifically to Xyrem, we are subject to risks and uncertainties common to companies in the pharmaceutical industry with development and commercial operations, including: the need to successfully integrate and grow our combined business after the EUSA Acquisition and Azur Merger; the need to obtain appropriate pricing and reimbursement for our products in an increasingly challenging environment; the ongoing regulation and oversight by the FDA, the U.S. Drug Enforcement Administration, and similar foreign regulatory agencies; the challenges of achieving and maintaining commercial success of our products; the dependence on key customers and sole source suppliers; the protection of intellectual property rights; and the difficulty and uncertainty of pharmaceutical product development and the uncertainty of clinical success and regulatory approval.

Business Acquisitions

Our condensed consolidated financial statements include the operations of an acquired business after the completion of the acquisition. We account for acquired businesses using the acquisition method of accounting. The acquisition method of accounting for acquired businesses requires, among other things, that most assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date, and that the fair value of acquired in-process research and development, or IPR&D, be recorded on the balance sheet. Also, transaction costs are expensed as incurred. Any excess of the purchase price over the assigned values of the net assets acquired is recorded as goodwill. Contingent consideration is included within the acquisition cost and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value at each reporting date until the contingency is resolved and changes in fair value are recognized in earnings.

Concentrations of Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents and marketable securities. Our investment policy permits investments in debt securities issued by the U.S. government or its agencies, corporate bonds or commercial paper issued by U.S. corporations, certain money market mutual funds, certain repurchase agreements, and tax-exempt obligations of states, agencies and municipalities and places restrictions on credit ratings, maturities, and concentration by type and issuer. We are exposed to credit risk in the event of a default by the financial institutions holding our cash, cash equivalents and marketable securities and issuers of investments to the extent recorded on the balance sheet.

We are also subject to credit risk from our accounts receivable related to our product sales. We monitor our exposure within accounts receivable and record a reserve against uncollectible accounts receivable as necessary. We extend credit to hospitals, pharmaceutical wholesale distributors and a specialty pharmaceutical distribution company, primarily in the United States, and to other international distributors. Customer creditworthiness is monitored and collateral is not required. We monitor deteriorating economic conditions in certain European countries which may result in variability of the timing of cash receipts and an increase in the average length of time that it takes to collect accounts receivable outstanding. Historically, we have not experienced significant credit losses on our accounts receivable and we do not expect to have write-offs or adjustments to accounts receivable which would have a material adverse effect on our financial position, liquidity or results of operations. As of June 30, 2012, five customers accounted for 71% of gross accounts receivable and one customer, Express Scripts Specialty Distribution Services, Inc. and its affiliate CuraScript, Inc., or Express Scripts, accounted for 46% of gross accounts receivable. As of December 31, 2011, Express Scripts accounted for 79% of gross accounts receivable.

We rely on certain sole suppliers for drug substance and certain sole manufacturing partners for certain of our marketed products and product candidates.

Foreign Currency

Our functional and reporting currency is the U.S. dollar. The assets and liabilities of our subsidiaries that have a functional currency other than the U.S. dollar are translated into U.S. dollars at the exchange rate prevailing at the balance sheet date with the results of operations of subsidiaries translated at the average exchange rate for the reporting period. The cumulative foreign currency translation adjustment is recorded as a component of accumulated other comprehensive loss in shareholders’ equity.

Transactions in foreign currencies are translated into the functional currency of the relevant subsidiary at the rate of exchange prevailing at the date of the transaction. The resulting monetary assets and liabilities are translated into the relevant functional currency at exchange rates prevailing at the balance sheet date. Gains and losses as a result of translation adjustments are recorded within “Other expense” in the accompanying condensed consolidated statements of income.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and on assumptions believed to be reasonable under the circumstances. Actual results could differ materially from those estimates.

Net Income per Ordinary Share

Basic net income per ordinary share is based on the weighted-average number of ordinary shares outstanding. Diluted net income per ordinary share is based on the weighted-average number of ordinary shares outstanding and potentially dilutive ordinary shares outstanding. Basic and diluted net income per ordinary share were computed as follows (in thousands, except per share amounts):


	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Numerator:

Dilutive effect of warrants		2,162		2,571		2,249		2,606

Weighted-average ordinary shares - diluted		60,554		46,601		59,319		46,238

Net income per ordinary share:
Basic	$	0.48	$	0.81	$	0.99	$	1.35

Diluted	$	0.45	$	0.71	$	0.92	$	1.19

Potentially dilutive ordinary shares from employee equity plans and warrants are determined by applying the treasury stock method to the assumed exercise of warrants and share options, the assumed vesting of outstanding restricted stock units, or RSUs, and the assumed issuance of ordinary shares under our employee stock purchase plan. The following table represents the weighted-average ordinary shares that were excluded from the computation of diluted net income per ordinary share for the periods presented because including them would have an anti-dilutive effect (in thousands):

All references to “ordinary shares” in the discussion and table above refer to Jazz Pharmaceuticals, Inc.’s common stock with respect to the comparative prior year periods and to Jazz Pharmaceuticals plc’s ordinary shares with respect to the current year periods. Our earnings per share in the comparative prior year periods were not impacted by the Azur Merger since each share of Jazz Pharmaceuticals, Inc. common stock issued and outstanding immediately prior to the effective time of the Azur Merger was canceled and automatically converted into and became the right to receive one ordinary share upon the consummation of the Azur Merger. This one-for-one conversion ratio is referred to in this report as the Azur exchange ratio.

Merger with Azur Pharma

On January 18, 2012, pursuant to an Agreement and Plan of Merger and Reorganization dated as of September 19, 2011, as amended, a wholly-owned subsidiary of Azur Pharma merged with and into Jazz Pharmaceuticals, Inc., with Jazz Pharmaceuticals, Inc. surviving the Azur Merger as a wholly-owned subsidiary of Jazz Pharmaceuticals plc. Prior to the Azur Merger, Azur Pharma changed its name to Jazz Pharmaceuticals plc. We believe the Azur Merger resulted in a company with a strengthened management team, a broader commercial organization and an efficient platform for further growth, with resources to build our product portfolio and a future pipeline.

At the effective time of the Azur Merger, each share of the common stock of Jazz Pharmaceuticals, Inc. issued and outstanding immediately prior to the effective time of the Azur Merger was canceled and automatically converted into and became the right to receive one ordinary share of Jazz Pharmaceuticals plc. Further, the stock options and stock awards outstanding under Jazz Pharmaceuticals, Inc.’s equity incentive plans were converted into stock options and stock awards to purchase or receive an equal number of ordinary shares of Jazz Pharmaceuticals plc with substantially the same terms and conditions, including the same per share exercise price, where applicable. In addition, outstanding warrants to purchase Jazz Pharmaceuticals, Inc. common stock were converted into substantially the same warrants to purchase an equal number of ordinary shares of Jazz Pharmaceuticals plc at the same per share exercise price. Our ordinary shares trade on the same exchange, The NASDAQ Global Select Market, and under the same trading symbol, “JAZZ,” as the Jazz Pharmaceuticals, Inc. common stock prior to the Azur Merger. We are deemed to be the successor to Jazz Pharmaceuticals, Inc. pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

The Azur Merger was accounted for as a reverse acquisition under the acquisition method of accounting, with Jazz Pharmaceuticals, Inc. treated as the accounting acquirer. Under the acquisition method of accounting, assets and liabilities of Azur Pharma were recorded at their respective estimated fair values as of the date of the Azur Merger and added to those of Jazz Pharmaceuticals, Inc., including an amount for goodwill representing the difference between the acquisition consideration and the estimated fair value of the identifiable net assets. The results of operations of the acquired Azur Pharma business and the estimated fair values of the assets acquired and liabilities assumed have been included in our condensed consolidated financial statements since the date of the Azur Merger.

The total acquisition consideration of $576.5 million was determined based on the market value of our ordinary shares that were held by the historic Azur Pharma shareholders immediately following the closing of the Azur Merger. The closing price of the Jazz Pharmaceuticals, Inc. common stock on January 17, 2012 ($46.64) was used to determine the fair value of consideration because the closing of the transaction on January 18, 2012 occurred prior to the opening of regular trading on January 18, 2012. Immediately following the consummation of the Azur Merger, 12,360,000, or 22%, of our ordinary shares were held by the persons and entities who acquired ordinary shares of Azur Pharma prior to the Azur Merger, and the remaining 43,838,000, or 78%, of the ordinary shares were held by the former stockholders of Jazz Pharmaceuticals, Inc.

During the three and six months ended June 30, 2012, we incurred $0 and $2.4 million, respectively, in transaction costs related to the Azur Merger, which primarily consisted of banking, legal, accounting and valuation-related expenses. These expenses were recorded in selling, general and administrative expense in the accompanying condensed consolidated statements of income. During the three and six months ended June 30, 2012, the contribution of the acquired Azur Pharma business to our total revenues was $20.8 million and $45.2 million, respectively. The portion of total expenses and net income associated with the acquired Azur Pharma business was not separately identifiable due to the integration with our operations.

The preliminary purchase price allocation resulted in the following amounts being allocated to the assets acquired and liabilities assumed at the closing date of the Azur Merger based upon their respective estimated fair values as summarized below (in thousands):


Cash and cash equivalents	$	81,751
Accounts receivable		12,975
Inventories		15,344
Property and equipment		370
Intangible assets		325,000
Goodwill		201,524
Other assets		4,862
Accounts payable and accrued liabilities		(52,148)
Purchased product rights liability		(11,899)
Above market lease obligation		(1,315)

Total purchase price	$	576,464

Asset categories acquired in the Azur Merger included working capital, long-term assets and liabilities, fixed assets and identifiable intangible assets, including IPR&D. The allocation of the purchase price for the Azur Merger has been prepared on a preliminary basis and we will finalize these amounts as we obtain the information necessary to complete the measurement process. Any changes resulting from facts and circumstances that existed as of the date of the Azur Merger may result in retrospective adjustments to the amounts recorded. These changes could be significant. We expect to finalize these amounts no later than one year from the date of the Azur Merger. Through June 30, 2012, we have not recorded any measurement period adjustments related to the Azur Merger.

The intangible assets as of the closing date of the Azur Merger included (in thousands):


Acquired developed technologies	$	323,000
In-process research and development		2,000

Total intangible assets	$	325,000

Intangible assets related to acquired developed technologies reflect the estimated fair value of the rights we acquired to those products in the Azur Merger. The fair value was determined using an income approach, which recognizes that the fair value of an asset is premised upon the expected receipt of future economic benefits such as earnings and cash inflows based on current sales projections and estimated direct costs for each product line. Indications of value are developed by discounting these benefits to their present worth at a discount rate that reflects the current return requirements of the market. Acquired developed technologies are finite-lived intangible assets and are being amortized over their estimated lives ranging from two to fifteen years.

The excess of purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents the goodwill amount resulting from the acquisition. We believe the factors that contributed to goodwill include synergies that are specific to our consolidated business and not available to market participants, the acquisition of a talented workforce that expands our expertise in business development and commercializing pharmaceuticals products as well as other intangible assets that do not qualify for separate recognition. We do not expect any portion of this goodwill to be deductible for tax purposes.

Acquisition of EUSA Pharma

On June 12, 2012, pursuant to an Agreement and Plan of Merger dated as of April 26, 2012, or the EUSA Acquisition Agreement, an indirect wholly-owned subsidiary of Jazz Pharmaceuticals plc merged with and into EUSA Pharma, with EUSA Pharma continuing as the surviving corporation and as an indirect wholly-owned subsidiary of Jazz Pharmaceuticals plc. The EUSA Acquisition has contributed to our expanded portfolio of specialty pharmaceutical products and product candidates, including in particular, Erwinaze, as well as given us a strengthened management team and an enhanced commercial platform, adding EUSA Pharma’s specialty commercial infrastructure in the United States and Europe and its international distribution network to our existing U.S. specialty product platform.

The EUSA Acquisition was accounted for using the acquisition method of accounting under which assets and liabilities of EUSA Pharma were recorded at their respective estimated fair values as of the date of the EUSA Acquisition and added to those of Jazz Pharmaceuticals plc including an amount for goodwill representing the difference between the acquisition consideration and the estimated fair value of the identifiable net assets. The results of operations of EUSA Pharma and the estimated fair values of the assets acquired and liabilities assumed have been included in our condensed consolidated financial statements since the date of the EUSA Acquisition.

At the closing of the EUSA Acquisition, we made an upfront cash payment of $678.4 million. Under the EUSA Acquisition Agreement, we also agreed to make an additional contingent payment of $50.0 million in cash if Erwinaze achieves U.S. net sales of $124.5 million in 2013. $50.0 million of the amount paid at closing was deposited in an escrow account, to be held for 12 months as partial security for our indemnification rights under the EUSA Acquisition Agreement. $25.0 million of the potential contingent payment, if payable, would be subject to reduction for indemnification claims, if any, that are not fully satisfied by the funds in the escrow account. The initial estimate of fair value of the contingent consideration was $35.1 million, which was recorded as a non-current liability and included in the total purchase price as summarized below:


Base payment	$	650,000
Cash acquired		54,117
Working capital and other adjustments		(25,719)

Upfront payment in accordance with agreement		678,398
Estimated fair value of contingent consideration		35,100

Total purchase price	$	713,498

During the three months and six months ended June 30, 2012, we incurred $8.9 million and $10.1 million, respectively, in transaction costs related to the EUSA Acquisition, which primarily consisted of banking, legal, accounting and valuation-related expenses. These expenses were recorded in selling, general and administrative expense in the accompanying condensed consolidated statements of income.

During both the three and six months ended June 30, 2012 periods, our statements of income included revenues of $8.0 million and a net loss of $1.6 million from the acquired EUSA Pharma business, as measured from the date of the EUSA Acquisition.

The preliminary purchase price allocation resulted in the following amounts being allocated to the assets acquired and liabilities assumed at the closing date of the EUSA Acquisition based upon their respective estimated fair values as summarized below (in thousands):


Cash and cash equivalents	$	54,117
Accounts receivable (1)		23,354
Inventories		36,360
Prepaid assets		6,212
Property and equipment		764
Intangible assets		616,970
Goodwill		206,452
Other assets		436
Accounts payable and accrued liabilities		(44,502)
Deferred tax liability		(186,591)
Other liabilities		(74)

Total purchase price	$	713,498

(1)

The estimated fair value of trade receivables acquired was $23.4 million. The gross contractual amount of trade receivables was $25.1 million and was recorded net of allowances for wholesaler chargebacks related to government rebate programs, cash discounts for prompt payment and doubtful accounts. We expect that $1.7 million of the gross contractual amount of trade receivables will be uncollectible.

Categories acquired in the EUSA Acquisition included working capital, long-term assets and liabilities, fixed assets and identifiable intangible assets, including IPR&D. The allocation of the purchase price for the EUSA Acquisition has been prepared on a preliminary basis and we will finalize these amounts as we obtain the information necessary to complete the measurement process. Any changes resulting from facts and circumstances that existed as of the date of the EUSA Acquisition may result in retrospective adjustments to the amounts recorded. These changes could be significant. We expect to finalize these amounts no later than one year from the date of the EUSA Acquisition. Through June 30, 2012, we have not recorded any measurement period adjustments related to the EUSA Acquisition since the date of acquisition.

The intangible assets as of the closing date of the EUSA Acquisition included (in thousands):


Acquired developed technologies	$	584,470
In-process research and development		32,500

Total intangible assets	$	616,970

Intangible assets related to acquired developed technologies reflect the estimated fair value of the rights we acquired to those products in the EUSA Acquisition. The fair value was determined using an income approach, which recognizes that the fair value of an asset is premised upon the expected receipt of future economic benefits such as earnings and cash inflows based on current sales projections and estimated direct costs for each product line. Indications of value are developed by discounting these benefits to their present worth at a discount rate that reflects the current return requirements of the market. Acquired developed technologies are finite-lived intangible assets and are being amortized over their estimated lives ranging from two to fourteen years.

The excess of purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents the goodwill amount resulting from the acquisition. We believe the factors that contributed to goodwill include synergies that are specific to our consolidated business and not available to market participants, the acquisition of a talented workforce and a platform for developing and commercializing pharmaceuticals products as well as other intangible assets that do not qualify for separate recognition. We do not expect any portion of this goodwill to be deductible for tax purposes.

Pro forma financial information (unaudited)

The following unaudited supplemental pro forma information presents the combined historical results of operations of Jazz Pharmaceuticals, Inc., Azur Pharma and EUSA Pharma for the three and six months ended June 30, 2012 and 2011, respectively, as if the Azur Merger and the EUSA Acquisition had each been completed on January 1, 2011. The pro forma financial information includes adjustments to reflect one time charges and amortization of fair value adjustments in the appropriate pro forma periods as though the companies were combined as of the beginning of 2011. These adjustments include:

•

An increase in amortization expense of $4.3 million and $10.2 million for the three and six months ended June 30, 2012, respectively, and $18.2 million and $36.6 million, respectively, for the three and six months ended June 30, 2011 related to the fair value of acquired identifiable intangible assets.

•

The exclusion of transaction-related expenses of $17.5 million and $33.3 million for the three and six months ended June 30, 2012, respectively, and $0.3 million for both the three and six months ended June 30, 2011.

•

A decrease in interest expense of $3.9 million and $1.1 million for the three and six months ended June 30, 2012, respectively, and an increase of $3.2 million and $7.3 million for the three and six months ended June 30, 2011, respectively, incurred on additional borrowings made to fund the acquisition of EUSA, as if the borrowings had occurred on January 1, 2011, offset by the elimination of actual interest expense incurred by EUSA during the periods presented.

•

The exclusion of other non-recurring expenses of $37.1 million and $47.0 million for the three and six months ended June 30,2012, respectively, and the inclusion of $5.7 million and $14.7 million for the three and six months ended June 30, 2011, primarily related to the fair value step-up to acquired inventory, share-based compensation incurred from the acceleration of stock option vesting upon closing of the Azur Merger and the EUSA Acquisition, a share-based liability granted to certain former Azur Pharma shareholders and integration-related expenses.

The unaudited pro forma results do not assume any operating efficiencies as a result of the consolidation of operations (in thousands, except per share data):

Collectively, cash and cash equivalents and marketable securities are considered available-for-sale. We use the specific-identification method for calculating realized gains and losses on securities sold and include them in interest expense, net in the condensed consolidated statements of income. Proceeds from sales of available-for-sale securities during the six months ended June 30, 2012 were $81.2 million and were used to partially fund the EUSA Acquisition. Gross realized gains and losses during the three and six months ended June 30, 2012 were insignificant. All available-for-sale securities held as of June 30, 2012 were cash and cash equivalents.

As of June 30, 2012, our available-for-sale securities included money market funds and certificates of deposits and their carrying values were approximately equal to their fair values. There were no transfers between the different levels of the fair value hierarchy in 2012.

As of December 31, 2011, our available-for-sale securities included corporate debt securities, obligations of U.S. government agencies, money market funds and certificates of deposit which were measured at fair value using Level 2 inputs. We reviewed trading activity and pricing for these investments as of the measurement date. Level 2 inputs, obtained from various third party data providers, represent quoted prices for similar assets in active markets, or these inputs were derived from observable market data, or if not directly observable, were derived from or corroborated by other observable market data. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. As of December 31, 2011, the aggregate fair value of available-for-sale securities which had unrealized losses was $43.6 million.

As part of the EUSA Acquisition, we agreed to make an additional contingent payment of $50.0 million in cash if Erwinaze achieves U.S. net sales of $124.5 million in 2013. The fair value measurement of this contingent consideration obligation is determined using unobservable (Level 3) inputs. These inputs include the probability of 2013 U.S. net sales of Erwinaze exceeding the $124.5 million threshold and the discount rate. A significant increase or decrease in the estimated probability of exceeding the milestone threshold would result in a significantly higher or lower fair value measurement, respectively. The range of the estimated contingent payment is from zero if 2013 U.S. net sales of Erwinaze are less than $124.5 million to $50.0 million if 2013 U.S. net sales of Erwinaze exceed $124.5 million. The fair value of the contingent consideration payable was estimated to be $35.1 million at June 12, 2012, the date of the EUSA Acquisition, and $35.3 million at June 30, 2012.

As of June 30, 2012, the estimated fair value of our $475.0 million term loan was $477.4 million and the carrying amount was $467.9 million. The fair value was determined using quotes from the administrative agent of our credit facility that are based on bid/ask prices of our term loan (Level 2). For additional information regarding our term loan see Note 7.

Long-Term Debt

7. Long-Term Debt

Term Loan and Revolving Credit Facility

On June 12, 2012, Jazz Pharmaceuticals plc, as guarantor, and Jazz Pharmaceuticals, Inc., as borrower, entered into a $575.0 million credit agreement with Barclays Bank PLC, as administrative agent and certain other lenders. The credit agreement provides for a six-year $475.0 million term loan and a five-year $100.0 million revolving credit facility, which includes a $10.0 million swing line loan sub facility and a $10.0 million letter of credit sub facility. The proceeds from the term loan were used to partially finance the EUSA Acquisition. Borrowings under the term loan bear interest, at our option, at a rate equal to either the LIBOR rate, plus an applicable margin of 4.25% per annum (subject to a 1.0% LIBOR floor), or the prime lending rate, plus an applicable margin equal to 3.25% per annum (subject to a 2.0% prime rate floor). Borrowings under the revolving credit facility bear interest, at our option, at a rate equal to either the LIBOR rate, plus an applicable margin of 4.00% per annum, or the prime lending rate, plus an applicable margin equal to 3.00% per annum, subject to reduction by 0.25% or 0.50% based upon our secured leverage ratio. The revolving credit facility has a commitment fee payable on the undrawn amount ranging from 0.25% to 0.50% per annum based upon our secured leverage ratio.

The obligations of Jazz Pharmaceuticals, Inc. under the credit agreement and any hedging or cash management obligations entered into with a lender are guaranteed by Jazz Pharmaceuticals plc and certain of its subsidiaries and are secured by substantially all of their assets.

We may make prepayments of principal without premium or penalty, except that a 1% premium would apply to a repayment via a repricing of the loan under the term loan effected on or prior to June 12, 2013. We are required to make mandatory prepayments of borrowings under the term loan (without payment of a premium) with (1) net cash proceeds from certain non-ordinary course asset sales (subject to reinvestment rights and other exceptions), (2) net cash proceeds from issuances of debt (other than certain permitted debt), (3) beginning with the fiscal year ending December 31, 2013, 50% of our excess cash flow as defined in the credit agreement (subject to increase to 75% if our secured leverage ratio exceeds 2.25 to 1.0, or decrease to 25% or 0% if our secured leverage ratio is equal to or less than 1.25 to 1.0 or 0.75 to 1.0, respectively), and (4) casualty proceeds and condemnation awards (subject to reinvestment rights and other exceptions).

Principal repayments of the term loan are due quarterly beginning in September 2012 and are equal to 5% of the original principal amount in the first year, 7.5% in the second year, 10% in each of the third and fourth years and 15% in each of the fifth and sixth years, with any remaining balance payable on the final maturity date.

The credit agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to Jazz Pharmaceuticals plc and its restricted subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness and dividends and other distributions. The credit agreement contains a financial covenant that requires Jazz Pharmaceuticals plc and its restricted subsidiaries to maintain a maximum secured leverage ratio beginning with the quarter ending September 30, 2012.

The $475.0 million principal amount of the term loan was recorded net of an original issue discount of $7.1 million. We incurred $15.0 million of debt issuance costs associated with the term loan which are recorded under the caption “Other long-term assets” in the accompanying condensed consolidated balance sheets. Unpaid debt issuance costs amounted to $1.6 million at June 30, 2012. As of June 30, 2012, the interest rate on the term loan was 5.25%. Interest expense associated with the term loan is recorded using the interest method and includes non-cash interest related to the debt discount and debt issuance costs. The effective interest rate on the term loan is 6.7%. The current portion of the carrying amount of the term loan was $23.8 million as of June 30, 2012.

Financing costs of $3.5 million associated with the revolving credit facility were deferred and are being amortized to interest expense on a straight-line basis over the life of the facility. As of June 30, 2012, we had not borrowed under the revolving credit facility.

Commitments and Contingencies

8. Commitments and Contingencies

Indemnification

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general indemnification, including indemnification associated with product liability or infringement of intellectual property rights. Our exposure under these agreements is unknown because it involves future claims that may be made but have not yet been made against us. To date, we have not paid any claims or been required to defend any action related to these indemnification obligations.

We have agreed to indemnify our executive officers, directors and certain other employees for losses and costs incurred in connection with certain events or occurrences, including advancing money to cover certain costs, subject to certain limitations. The maximum potential amount of future payments we could be required to make under the indemnification obligations is unlimited; however, we maintain insurance policies that may limit our exposure and may enable us to recover a portion of any future amounts paid. Assuming the applicability of coverage, the willingness of the insurer to assume coverage, and subject to certain retention, loss limits and other policy provisions, we believe the fair value of these indemnification obligations is not significant. Accordingly, we have not recognized any liabilities relating to these obligations as of June 30, 2012 and December 31, 2011. No assurances can be given that the covering insurers will not attempt to dispute the validity, applicability, or amount of coverage without expensive litigation against these insurers, in which case we may incur substantial liabilities as a result of these indemnification obligations.

Lease and Other Commitments

We have noncancelable operating leases for our office buildings and we are obligated to make payments under noncancelable operating leases for automobiles used by our sales force. Future minimum lease payments under our noncancelable operating leases at June 30, 2012 were as follows (in thousands):


Year Ending December 31,	Lease Payments

2014		5,713
2015		4,957
2016		4,158
Thereafter		5,755

Total	$	30,058

In May 2012, we entered into an operating lease agreement for our new headquarters in Dublin for a term of ten years, we amended and extended the operating lease for our existing Philadelphia office building for a term of four years and we entered into a new operating sublease for additional office space in Palo Alto near our existing office location for a term of five years. As a result of the EUSA Acquisition, we have additional operating leases which are included in the table above.

As of June 30, 2012, we had $45.7 million of noncancelable purchase commitments under agreements with contract manufacturers, $42.5 million of which is due within one year.

Legal Proceedings

We are involved in several legal proceedings, including the following matters:

Xyrem ANDA Matter: On October 18, 2010, we received a Paragraph IV Patent Certification notice, or Paragraph IV Certification, from Roxane Laboratories, Inc., or Roxane, that it filed an ANDA with the United States Food and Drug Administration, or FDA, requesting approval to market a generic version of Xyrem. Roxane’s Paragraph IV Certification alleged that all five patents then listed for Xyrem in the FDA’s publication “Approved Drug Products with Therapeutic Equivalence Evaluations”, or Orange Book, on the date of the Paragraph IV Certification are invalid, unenforceable or not infringed by Roxane’s proposed generic product. On November 22, 2010, we filed a lawsuit against Roxane in response to Roxane’s Paragraph IV Certification in the United States District Court for the District of New Jersey, or the District Court. We are seeking a permanent injunction to prevent Roxane from introducing a generic version of Xyrem in violation of our patents. In accordance with the Hatch-Waxman Act, as a result of having filed a timely lawsuit against Roxane, FDA approval of Roxane’s ANDA will be stayed until the earlier of (i) April 18, 2013, which is 30 months from our October 18, 2010 receipt of Roxane’s Paragraph IV certification notice, or (ii) a District Court decision finding that the identified patents are invalid, unenforceable or not infringed. An additional method of use patent covering the distribution system for Xyrem issued in December 2010 and is listed in the Orange Book, and we amended our lawsuit against Roxane on February 4, 2011 to include the additional patent in the litigation in response to Roxane’s Paragraph IV Certification against this patent, as well as another patent which is not listed in the Orange Book. Another method of use patent covering the distribution system for Xyrem issued in February 2011 and is listed in the Orange Book, and we amended our lawsuit against Roxane on May 2, 2011 to include this additional patent in response to Roxane’s Paragraph IV Certification against it. On April 26, 2012, the District Court held a Markman hearing, a pretrial hearing in which the trial judge construes the claims of a patent, and the discovery phase of the proceeding is ongoing. No trial date has been scheduled. We cannot predict the outcome of this matter.

On May 18, 2012, we submitted a Citizen Petition to the FDA addressing the legal and scientific bases for requiring in vivo bioequivalence studies for generic formulations of Xyrem and requesting that the FDA: publish in the Orange Book bioequivalence requirements specifying whether in vitro or in vivo bioequivalence studies, or both, are required for ANDAs referencing Xyrem; not accept for review, review, or approve any ANDA referencing Xyrem unless and until the FDA has published bioequivalence requirements in the Orange Book specifying whether in vitro bioequivalence studies, in vivo bioequivalence studies, or both, are required for such ANDAs; and require in vivo bioequivalence studies for any sodium oxybate drug product for which approval is sought in an ANDA referencing Xyrem to the extent such drug product differs from Xyrem in manufacturing process, pH, excipients, impurities, degradants or contaminants.

On July 10, 2012, we submitted a second Citizen Petition to the FDA addressing the requirements for submission of any ANDA referencing Xyrem. This petition asks the FDA to rescind the acceptance of any previously-accepted ANDA referencing Xyrem, including the Roxane ANDA, that did not contain a proposed risk management system at the time it was accepted for review, because such ANDA would not have demonstrated, as required by law, that the new generic drug product would have the same labeling and conditions of use as Xyrem. This petition further requests that the FDA (i) not accept for review any ANDA referencing Xyrem that does not contain, at the time of its submission, a proposed risk management system sufficient to demonstrate that the new generic drug product has the same labeling and conditions of use as Xyrem; and (ii) determine that if any sponsor, including Roxane, of an ANDA referencing Xyrem that did not contain, at the time it was accepted for review, a proposed risk management system later submits, or resubmits, an ANDA that contains a proposed risk management system sufficient to demonstrate that the new generic drug product would have the same labeling and conditions of use of Xyrem, such ANDA should not be approved for a period of up to thirty months beginning on the date we receive notice of any Paragraph IV certifications contained in such new ANDA, to the extent that we avail ourselves of our right to initiate a patent infringement action based on such notice. We believe that the FDA’s acceptance of Roxane’s ANDA caused the thirty-month stay under the Hatch-Waxman Act and the related patent litigation between the parties to begin prematurely in a manner contrary to applicable law. We cannot predict when or if the FDA will respond to, or otherwise take any action with respect to, either of our Citizen Petitions, or the effect of any such response or action on the timing of the potential introduction of a generic version of Xyrem or on the ongoing litigation between us and Roxane.

Luvox CR ANDA Matters. In August 2009, we received a Paragraph IV Certification from Actavis Elizabeth, LLC, or Actavis, advising that Actavis had filed an ANDA with the FDA seeking approval to market a generic version of Luvox CR. Actavis’ Paragraph IV Certification alleged that the United States patent covering Luvox CR, which is owned by Elan Pharma International Limited, or Elan, which has subsequently transferred its rights to Alkermes Pharma Ireland Limited, or Alkermes, and licensed to us, is invalid on the basis that the inventions claimed therein were obvious. On October 6, 2009, we and Elan, as plaintiffs, filed a lawsuit against Actavis in the United States District Court for the District of Delaware claiming infringement of the Alkermes patent. On September 10, 2011, we received a Paragraph IV Certification from Torrent Pharma Limited, or Torrent, advising us that it had filed an ANDA with the FDA requesting approval to market a generic version of Luvox CR. On October 21, 2011, we and Alkermes, as plaintiffs, filed a lawsuit against Torrent in the United States District Court for the District of Delaware asserting infringement of the Alkermes patent. On April 5, 2012 and April 10, 2012, we and Alkermes entered into settlement agreements with Actavis and Torrent, respectively. Under the agreements, we, Alkermes and each of Actavis and Torrent agreed to dismiss all of the claims brought in the litigation without prejudice, each of Actavis and Torrent agreed not to contest the validity or enforceability of the Alkermes patent in the United States, and we, Alkermes and each of Actavis and Torrent agreed to release each other from all claims arising in the litigation or relating to the product each of Actavis and Torrent intends to market under its ANDA. In addition, we granted a sublicense to each of Actavis and Torrent of our rights to have manufactured, market and sell a generic version of Luvox CR in the United States. The sublicenses will commence on April 15, 2014 or earlier upon the occurrence of certain events.

FazaClo ANDA Matters: Azur Pharma received Paragraph IV Certifications from three generics manufacturers, Barr Laboratories, Inc.; Novel Laboratories, Inc.; and Mylan Pharmaceuticals, Inc., indicating that ANDAs had been filed with the FDA requesting approval to market generic versions of FazaClo LD. Azur Pharma and CIMA Labs Inc., or CIMA, a subsidiary of Teva Pharmaceutical Industries Limited, or Teva, our licensor and the entity whose drug-delivery technology is incorporated into FazaClo LD, filed a lawsuit in response to each certification claiming infringement based on such certification in the United States District Court for the District of Delaware. On July 6, 2011, CIMA, Azur Pharma and Teva, which had acquired Barr Laboratories, Inc., entered into an agreement settling the patent litigation and Azur Pharma granted a sublicense to an affiliate of Teva of Azur Pharma’s rights to have manufactured, market and sell a generic version of both FazaClo LD and FazaClo HD, as well as an option for supply of authorized generic product. The sublicense for FazaClo LD commenced in July 2012, and the sublicense for FazaClo HD will commence in May 2015 or earlier upon the occurrence of certain events. Teva has exercised its option for supply of an authorized generic product for Fazaclo LD, and we are addressing the FDA requirements to permit a launch of the authorized generic product. The Novel Laboratories, Inc. and Mylan Pharmaceuticals, Inc. matters have been stayed pending reexamination of the patents in the suit. We cannot predict the outcome of the matters with Novel Laboratories, Inc. and Mylan Pharmaceuticals, Inc., the reexamination proceedings, or when the stays will be lifted.

Cutler Matter: On October 19, 2011, Dr. Neal Cutler, one of the original owners of FazaClo, filed a complaint against Azur Pharma and one of its subsidiaries, as well as Avanir Pharmaceuticals, Inc., or Avanir, in California Superior Court in the County of Los Angeles. The complaint alleges that Azur Pharma and its subsidiary breached certain contractual obligations. Azur Pharma acquired rights to FazaClo from Avanir in 2007. The complaint alleges that as part of the acquisition of FazaClo, Azur Pharma’s subsidiary agreed to assume certain contingent payment obligations to Dr. Cutler. The complaint further alleges that certain contingent payments are due because revenue thresholds have been achieved, entitling Dr. Cutler to either a $10.5 million or $25.0 million contingent payment, plus unspecified punitive damages and attorneys’ fees. On March 14, 2012, the Superior Court granted our petition to compel arbitration of the dispute in New York and stayed the Superior Court litigation. We submitted a complaint in arbitration alleging that Dr. Cutler’s suit had been improperly filed in Los Angeles and seeking a declaratory judgment that we have complied with all contractual obligations to Dr. Cutler. On July 25, 2012, the arbitrator dismissed the arbitration on the grounds that the parties’ dispute falls outside the scope of the arbitration clause in the applicable contract. This matter, like all litigation, carries certain risks, and there can be no assurance of the outcome.

From time to time we are involved in legal proceedings arising in the ordinary course of business. We believe there is no other litigation pending that could have, individually or in the aggregate, a material adverse effect on our results of operations or financial condition.

Shareholders' Equity

6 Months Ended

Shareholders' Equity

9. Shareholders’ Equity

Shares and Additional Paid-In Capital

Following the Azur Merger, our capital structure is comprised of ordinary shares and euro deferred shares. The outstanding 4,000,000 non-voting euro deferred shares of €0.01 each are held by nominees and were issued to satisfy the statutory minimum Euro-denominated share capital required for a public limited company incorporated in Ireland. The non-voting euro deferred shares have no right to receive dividends, no rights to attend and vote at our general meetings, are redeemable only at our option and have no substantive right to participate in a distribution of assets upon a winding up of our company. All references to common stock in the comparative prior year reports in the discussion and table below were replaced with references to ordinary shares to reflect the capital structure of Azur Pharma, the legal acquirer in the Azur Merger. Our earnings per share in comparative periods were not impacted by the Azur Merger as a result of the one-for-one Azur exchange ratio.

The total purchase price consideration of $576.5 million related to the Azur Merger was recorded by increasing total par value of our ordinary shares and euro deferred shares by $1,236 and $54,862, respectively, by creating a capital redemption reserve of $0.5 million as required by Irish company law, to preserve permanent capital in the company; and by increasing our additional paid-in capital by $575.9 million.

The following table presents a summary of ordinary shares issued and related cash proceeds and payments (in thousands):


	Six Months Ended June 30, 2012				Six Months Ended June 30, 2011
	Shares		Cash		Shares		Cash
Azur Merger		12,360	$	-		-	$	-

Totals		15,067	$	(6,726)		1,729	$	9,411

Share-based compensation expense related to share options, restricted stock units, ordinary shares credited to the directors’ phantom share accounts and grants under our employee stock purchase plan was classified as follows (in thousands):

Total share-based compensation expense	$	5,258	$	3,415	$	8,539	$	6,563

Share Options

The table below shows (i) the number of shares underlying options to purchase our ordinary shares granted to employees, (ii) the weighted-average grant date fair value per share of those share options, and (iii) certain information about the weighted-average assumptions used in the Black-Scholes option pricing model which was used to estimate the grant date fair value per share:


	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011

Expected dividend yield		0.0	%		0.0	%		0.0	%		0.0	%

Restricted Stock Units

In the six months ended June 30, 2012, we granted 452,793 RSUs covering an equal number of our ordinary shares to employees with a weighted-average grant date fair value of $51.59. The fair value of RSUs is determined on the date of grant based on the market price of our ordinary shares as of that date. The fair value of the RSUs is recognized as expense ratably over the vesting period of four years.

As of June 30, 2012, total compensation cost not yet recognized related to unvested share options and RSUs was $48.5 million, which is expected to be recognized over a weighted-average period of 2.8 years.

Related Party Transactions

11. Related Party Transactions

In connection with the Azur Merger, we assumed a lease for office space in Dublin, Ireland which expires in October 2029. The lease agreement is with Seamus Mulligan, the former Chief Executive Officer of Azur Pharma, who is currently our Chief Business Officer, International Business Development and a member of our board of directors. Rentals paid on this lease amounted to $0.1 million in the six months ended June 30, 2012. There were no amounts unpaid at June 30, 2012.

In May 2011, Azur Pharma entered into an agreement with Circ Pharma Limited/Circ Pharma Research and Development Limited, or Circ, companies controlled by Seamus Mulligan, whereby it obtained an option to license certain rights and assets in relation to Tramadol (a chronotherapeutic formulation) and to conduct certain development activities. Azur Pharma paid Circ $250,000 for this option in 2011. Effective July 2012, we terminated the agreement at no cost.

In March 2012, we entered into an underwriting agreement with two underwriters and certain selling shareholders, pursuant to which the selling shareholders agreed to sell to the underwriters 7.9 million of our ordinary shares, resulting in aggregate gross proceeds to the selling shareholders of approximately $390.7 million. The selling shareholders included entities affiliated with certain members of our board of directors, four of our directors and four of our executive officers at the time of the agreement. We did not receive any proceeds from the sale of our ordinary shares by the selling shareholders in the offering, and we agreed to pay expenses of approximately $0.4 million in connection with this offering.

Income Tax

Income Tax

13. Income Tax

Our provision for income taxes was $6.6 million and $12.1 million for the three and six months ended June 30, 2012, respectively, compared to zero for the same periods in 2011. Our effective tax rate was 19.5% and 18.1% for the three and six months ended June 30, 2012, respectively, compared to our effective tax rate of zero for the same periods in 2011. The provision for income taxes for the three and six months ended June 30, 2012 was for taxes in foreign jurisdictions including the U.S. subsequent to the EUSA Acquisition in June 2012. During 2011, we had operations only in the U.S. and made no provision for income taxes due to our utilization of federal net operating loss carryforwards to offset both regular taxable income and alternative minimum taxable income and to our utilization of deferred state tax benefits. The 2012 effective tax rates were higher than the Irish statutory rate of 12.5% due to income taxable at a rate higher than the Irish statutory rate partially offset by a valuation allowance release in connection with the utilization of current year net operating losses.

We record a deferred tax asset or liability based on the difference between the financial statement and tax basis of our assets and liabilities, as measured by enacted jurisdictional tax rates assumed to be in effect when these differences reverse. Our deferred tax assets are composed primarily of U.S. federal net operating loss carryforwards and tax credit carryforwards. Based on available objective evidence, management believes it is more likely than not that these deferred tax assets are not recognizable and will not be recognizable until we have sufficient taxable income because of the risks and uncertainties described in Note 1. Accordingly, net deferred tax assets have been fully offset by a valuation allowance. We will continue to evaluate the need for a valuation allowance by jurisdiction on our deferred tax assets during each reporting period. If and when we reverse the valuation allowance, we will record a tax benefit in our consolidated statement of income. As of June 30, 2012, our deferred tax liability of $185.7 million primarily related to intangible assets and IPR&D acquired in the EUSA Acquisition.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
