Organization And Description Of Business [Abstract]
Organization And Description Of Business	1. Organization and Description of Business Jazz Pharmaceuticals, Inc. was incorporated in California in March 2003 and reincorporated in Delaware in January 2004. On January 18, 2012, the merger contemplated by the Agreement and Plan of Merger and Reorganization dated as of September 19, 2011, as amended, was consummated in connection with which Jazz Pharmaceuticals, Inc. became a wholly-owned subsidiary of Jazz Pharmaceuticals plc (previously known as Azur Pharma Public Limited Company, or Azur Pharma). Jazz Pharmaceuticals, Inc. is treated as the acquiring company in the merger for accounting purposes, and the merger is being accounted for as a reverse acquisition under the acquisition method of accounting for business combinations. For additional information regarding the merger see Note 15. Prior to the merger, Jazz Pharmaceuticals, Inc. was a specialty biopharmaceutical company focused on the identification, development and commercialization of pharmaceutical products to meet important unmet medical needs in focused therapeutic areas. Marketed products of Jazz Pharmaceuticals, Inc. consisted of Xyrem (sodium oxybate), which is the only product approved by the United States Food and Drug Administration, or FDA, for the treatment of both cataplexy and excessive daytime sleepiness in patients with narcolepsy, and Luvox CR (fluvoxamine maleate) marketed for the treatment of obsessive compulsive disorder. Except where specifically noted or the context otherwise requires, the use of terms such as "Jazz Pharmaceuticals", "we", "our" and "us" in these Notes to Consolidated Financial Statements refers to Jazz Pharmaceuticals, Inc.

Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Jazz Pharmaceuticals, Inc. (a wholly-owned subsidiary of Jazz Pharmaceuticals plc) and its wholly-owned subsidiaries, Orphan Medical, LLC, formerly Orphan Medical, Inc., or Orphan Medical, and JPI Commercial, LLC after elimination of intercompany transactions and balances. Our consolidated financial statements include the operations of an acquired business after the completion of the acquisition; accordingly these consolidated financial statements only include the accounts of Jazz Pharmaceuticals, Inc. for all periods presented because the merger was not effective until January 18, 2012.

Significant Risks and Uncertainties

We are subject to risks common to companies in the pharmaceutical industry with development and commercial operations including, but not limited to, risks and uncertainties related to commercial success and acceptance of our products by patients, physicians and payors, competition from branded and generic products, regulatory approvals, regulatory requirements, including those of the United States Food and Drug Administration, or FDA, and the United States Drug Enforcement Administration dependence on key customers and sole source suppliers and protection of intellectual property rights. In addition, most of our revenues are derived from sales of one product, Xyrem. During 2010, an abbreviated new drug application, or ANDA, was filed with the 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. We cannot predict the timing or outcome of this litigation. If an ANDA for Xyrem is approved and a generic version of Xyrem is introduced, our sales of Xyrem would be adversely affected.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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.

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 pharmaceutical wholesale distributors and a specialty pharmaceutical distribution company, primarily in the United States, and to international distributors. Customer creditworthiness is monitored and collateral is not required. Historically, we have not experienced significant credit losses on our accounts receivable. One customer, Express Scripts Specialty Distribution Services, Inc. and its affiliate CuraScript, Inc., or Express Scripts, accounted for 79% of gross accounts receivable as of both December 31, 2011 and December 31, 2010.

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

Cash Equivalents and Marketable Securities

We consider all highly liquid investments, readily convertible to cash, that mature within three months or less from date of purchase to be cash equivalents.

Marketable securities are investments in debt securities with maturities of less than one year from the balance sheet date, or securities with maturities of greater than one year that are specifically identified to fund current operations. Collectively, cash equivalents, restricted cash and marketable securities are considered available-for-sale and are recorded at fair value. Unrealized gains and losses, net of tax, are recorded in other comprehensive income and included as a separate component of stockholders' equity. We use the specific-identification method for calculating realized gains and losses on securities sold. Realized gains and losses and declines in value judged to be other than temporary on marketable securities are included in interest income in the statement of operations. Realized gains and losses on sales of marketable securities have not been significant.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined using the first-in, first-out method for all inventories. Our policy is to write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected requirements. The estimate of excess quantities is subjective and primarily dependent on our estimates of future demand for a particular product. If the estimate of future demand is too high, we may have to increase the reserve for excess inventory for that product and record a charge to cost of product sales. For product candidates that have not been approved by the FDA, inventory used in clinical trials is expensed at the time of production and recorded as research and development expense. For products that have been approved by the FDA, inventory used in clinical trials is expensed at the time the inventory is packaged for the clinical trial. Prior to receiving FDA approval costs related to purchases of the active pharmaceutical ingredient and the manufacturing of the product candidate are recorded as research and development expense. All direct manufacturing costs incurred after approval are capitalized into inventory.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are three to five years. Leasehold improvements are amortized over the shorter of the noncancelable term of our operating lease or their economic useful lives. Maintenance and repairs are charged to operations as incurred.

Goodwill and Intangible Assets

Goodwill

Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. We have determined that we operate in a single segment and have a single reporting unit associated with the development and commercialization of pharmaceutical products. The annual test for goodwill impairment is a two-step process. The first step is a comparison of the fair value of the reporting unit with its carrying amount, including goodwill. If this step indicates impairment, then in the second step, the loss is measured as the excess of recorded goodwill over its implied fair value. Implied fair value is the excess of the fair value of the reporting unit over the fair value of all identified assets and liabilities. Management tests goodwill for impairment annually in October and whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Intangible Assets

Intangible assets consist primarily of purchased developed technology and trademarks. Intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from three to ten years. The estimated useful lives associated with intangible assets are consistent with the estimated lives of the associated products and may be modified when circumstances warrant. Once an intangible asset is fully amortized, the gross costs and accumulated amortization are removed from the consolidated balance sheet. We evaluate purchased intangibles and other long-lived assets, other than goodwill, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. The amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset.

Revenue Recognition

Revenues are recognized when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable and collection is reasonably assured. Revenue from sales transactions where the buyer has the right to return the product is recognized at the time of sale only if (i) the seller's price to the buyer is substantially fixed or determinable at the date of sale, (ii) the buyer has paid the seller, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of the product, (iii) the buyer's obligation to the seller would not be changed in the event of theft or physical destruction or damage of the product, (iv) the buyer acquiring the product for resale has economic substance apart from that provided by the seller, (v) the seller does not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (vi) the amount of future returns can be reasonably estimated.

In evaluating arrangements with multiple elements we consider whether components of the arrangement represent separate units of accounting based upon whether certain criteria are met, including whether the delivered element has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered items. This evaluation requires subjective determinations and requires management to make judgments about the fair value of individual elements and whether such elements are separable from other aspects of the contractual relationship. The consideration received in such arrangements is allocated among the separate units of accounting based on the relative selling price method under which the selling price for each deliverable is determined using vendor-specific objective evidence of selling price, if it exists; otherwise, third-party evidence of selling price. If vendor-specific objective evidence and third-party evidence of selling price are not available for a deliverable, we will use our best estimate of the selling price for that deliverable when applying the relative selling price method. The applicable revenue recognition criteria are applied to each of the separate units.

Payments received in advance of work performed or milestones achieved are recorded as deferred revenues and recognized when the service is provided or the milestone is achieved, as applicable.

Product Sales, Net

We sell Xyrem in the United States to a single central pharmacy, Express Scripts. We recognize revenues from sales of Xyrem within the United States upon transfer of title, which occurs when Express Scripts removes product from our consigned inventory location at its facility for shipment directly to a patient. We accept returns from Express Scripts of any product returned by patients to Express Scripts with defects that were not reasonably discoverable upon receipt of the consigned product by Express Scripts. Based on our experience over the past six years since we acquired the rights to Xyrem, product returns to Express Scripts from patients are rare. We provide Express Scripts with a credit for product returned by patients. During 2011, we issued credits totaling $0.2 million for returned product.

We sell limited quantities of Xyrem to UCB Pharma Limited, or UCB, for sale in territories outside of North America, and to Valeant Canada Limited, for sale in Canada, under license and distribution agreements. The agreements provide our international licensees with a fixed period of time, typically 30 to 60 days, after delivery to inspect and reject shipments for failure to meet specifications. We do not recognize revenue on the sales to our international licensees until the right of return has lapsed, which occurs when we are notified of their acceptance, or when the time for them to inspect or reject a shipment has lapsed, if earlier.

We grant rights to our wholesaler customers to return product six months prior to and up to twelve months after product expiration and issue credits which may be applied against existing or future invoices. In October 2010, we started recognizing revenue from sales of Luvox CR upon shipment to our wholesaler customers and recorded an estimated amount of product returns. Our liability for estimated future returns as of December 31, 2011 and 2010 was $4.3 million and $3.5 million, respectively.

Revenues from sales of products within the United States are recorded net of estimated allowances for returns, specialty distributor fees, wholesaler fees, prompt payment discounts, government rebates, government chargebacks, coupon programs and rebates under managed care plans. Calculating certain of these items involves estimates and judgments based on sales or invoice data and historical experience. Adjustments to estimates for these allowances have not been material.

Royalties and Contract Revenues

We receive royalties from third parties based on sales of our products under licensing and distribution arrangements. For those arrangements where royalties are reasonably estimable, we recognize revenues based on estimates of royalties earned during the applicable period, and adjust for differences between the estimated and actual royalties in the following quarter. Historically, these adjustments have not been significant.

Our contract revenues consist of fees and milestone payments. Nonrefundable fees where we have no continuing performance obligations are recognized as revenues when there is persuasive evidence of an arrangement and collection is reasonably assured. In situations where we have continuing performance obligations, nonrefundable fees are deferred and are recognized ratably over our projected performance period. We recognize at-risk milestone payments, which are typically related to regulatory, commercial or other achievements by us or our licensees and distributors, as revenues when the milestone is accomplished and collection is reasonably assured. Sales-based milestone payments are typically payments made to us that are triggered when aggregate net sales of a product by a collaborator for a specified period (for example, an annual period) reach an agreed upon threshold amount. We recognize sales-based milestone payments from a collaborator when the event which triggers the obligation of payment has occurred, there is no further obligation on our part in connection with the payment, and collection is reasonably assured. Refundable fees are deferred and recognized as revenues upon the later of when they become nonrefundable or when our performance obligations are completed.

Cost of Product Sales

Cost of product sales includes third party manufacturing and distribution costs, the cost of drug substance, royalties due to third parties on product sales, product liability and cargo insurance, FDA user fees, freight, shipping, handling and storage costs and salaries and related costs of employees involved with production. Excluded from cost of product sales, as shown on the consolidated statements of operations, is amortization of acquired developed technology of $7.2 million, $7.2 million and $6.6 million for 2011, 2010 and 2009, respectively.

Research and Development

Research and development expenses consist of expenses incurred in identifying, developing and testing our product candidates. These expenses consist primarily of fees paid to contract research organizations and other third parties to assist us in managing, monitoring and analyzing results from our clinical trials, clinical trial costs paid to sites and investigators' fees, costs of non-clinical studies, including toxicity studies in animals, costs of contract manufacturing services, costs of materials used in clinical trials and non-clinical studies, fees paid to third parties for development candidates or drug delivery or formulation technologies that we have licensed, allocated expenses, such as facilities and information technology that support our research and development activities, and related personnel expenses, including stock-based compensation. Research and development costs are expensed as incurred, including payments made under license agreements. For product candidates that have not been approved by the FDA, inventory used in clinical trials is expensed at the time of production and recorded as research and development expense. For products that have been approved by the FDA, inventory used in clinical trials is expensed at the time the inventory is packaged for the trial and therefore is not included in inventory.

Advertising Expenses

We expense the costs of advertising, including promotional expenses, as incurred. Advertising expenses for 2011, 2010 and 2009 were $1.0 million, $1.6 million and $0.4 million, respectively.

Income Taxes

We utilize the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and the tax bases of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Comprehensive Income (Loss)

Comprehensive income (loss) includes net income (loss) and all changes in stockholders' equity (deficit) during a period, except for those changes resulting from investments by stockholders or distributions to stockholders. Comprehensive income (loss) was as follows (in thousands):


	December 31,
	2011			2010		2009
Net income (loss)	$	124,984		$	32,778	$	(6,836	)
Unrealized loss on available-for-sale investments		(31	)		—		(4	)

Comprehensive income (loss)	$	124,953		$	32,778	$	(6,840	)

Net Income (Loss) Per Common Share

Basic and diluted net income (loss) per common share is computed using the weighted-average number of shares of common stock outstanding as follows (in thousands, except per share amounts):


	Year Ended December 31,
	2011		2010		2009
Numerator:
Net income (loss)	$	124,984	$	32,778	$	(6,836	)

Denominator:
Weighted-average common shares outstanding—basic		41,499		36,343		30,018
Dilutive effect of employee equity incentive and purchase plans		2,715		1,720		—
Dilutive effect of warrants		2,584		1,348		—

Weighted-average common shares outstanding—diluted		46,798		39,411		30,018

Net income (loss) per share:
Basic	$	3.01	$	0.90	$	(0.23	)

Diluted	$	2.67	$	0.83	$	(0.23	)

Potentially dilutive common shares from employee stock plans and warrants were not included in the diluted net loss per share for 2009 because the inclusion of such shares would have had an anti-dilutive effect.

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


	Year Ended December 31,
	2011		2010		2009
Warrants to purchase common stock		—		—		3,759
Options to purchase common stock		1,038		3,211		2,843
Restricted stock units		—		—		38

Total		1,038		3,211		6,640

Stock-Based Compensation

We account for compensation cost for all stock-based awards at fair value on the date of grant. The fair value is recognized as expense over the service period, net of estimated forfeitures, using the straight-line method for stock options and restricted stock units and using the ratable method for awards under our employee stock purchase program. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. We primarily consider historical experience when estimating expected forfeitures.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board, or the FASB, issued guidance which changes certain fair value measurement principles and increases disclosure requirements, particularly for fair value measurements subject to significant judgment and is effective for fiscal years beginning after December 15, 2011. The adoption of this amendment will not have a material impact on our results of operations or financial position.

In June and December 2011, the FASB issued amended guidance on the presentation of comprehensive income in financial statements. The amendment provides companies the option to present the components of net income and other comprehensive income either as one continuous statement of comprehensive income or as two separate but consecutive statements. The amendment eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this amendment will not have a material impact on our results of operations or financial position.

In September 2011, the FASB issued amended guidance related to the goodwill impairment test which allows companies to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this amendment will not have a material impact on our results of operations or financial position.

Totals								$	157,898							$	45,194

All available-for-sale securities held as of December 31, 2011 had contractual maturities of less than one year, and no securities were sold in 2011. No available-for-sale securities held as of December 31, 2011 had been in a continuous loss position for more than 12 months. The aggregate fair value of available-for-sale securities which had unrealized losses as of December 31, 2011 was $43.6 million.

Gross unrealized losses on investments as of December 31, 2011, related to the available-for-sale securities were insignificant and we believe the impairment was temporary. In determining that the decline in fair value of these securities was temporary, we considered the length of time each security was in an unrealized loss position and the extent to which fair value was less than cost. In addition, we do not intend to sell these securities and it is not more likely than not that we will be required to sell these securities before the recovery of their amortized cost basis.

The following table summarizes, by major security type, our available-for-sale securities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands):


	December 31, 2011						December 31, 2010
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Total Estimated Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)		Total Estimated Fair Value

Total available-for-sale securities	$	48,518	$	76,073	$	124,591	$	25,046	$	25,046

Available-for-sale securities consist of corporate debt securities, obligations of U.S. government agencies and certificates of deposit and were measured at fair value using Level 2 inputs. We review 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.

There were no transfers between Level 1 and Level 2 of the fair value hierarchy in 2011.

In 2011, we repaid in full our long-term debt (see Note 6). Prior to the extinguishment of our long-term debt, we estimated the fair value of our long-term debt using a discounted cash flow analysis based on our incremental borrowing rates for similar types of borrowing arrangements. The carrying amount and the estimated fair value of our long-term debt were as follows (in thousands):


	December 31, 2011				December 31, 2010

Debt And Financing Obligations	12 Months Ended
Debt And Financing Obligations	Dec. 31, 2011
Debt And Financing Obligations [Abstract]
Debt And Financing Obligations	6. Debt and Financing Obligations *Term Loan and Revolving Credit Facility* In December 2011, we terminated a credit agreement we entered into in June 2010, which was scheduled to mature in June 2013. The credit agreement included a $15.0 million revolving credit facility and a $50.0 million three-year term loan which provided for quarterly principal payments of $4.2 million. In July 2011, we repaid all amounts due under the term loan. In 2011, as a result of the early repayment of the term loan and the termination of the credit agreement, we recorded a loss on extinguishment of debt of $1.2 million, which consisted of a $0.8 million non-cash charge related to the write-off of unamortized debt issuance costs and a debt discount and the remainder related to a prepayment penalty and a termination fee. In 2010, we repaid $119.5 million principal amount due under a previous debt agreement. As a result of the repayment of amounts due under the previous debt agreement, we recorded a loss on extinguishment of debt of $12.3 million in 2010, which consisted of a $3.8 million non-cash charge related to the write-off of unamortized debt issuance costs and a debt discount and an $8.5 million prepayment penalty. As of December 31, 2010, the $41.7 million principal amount of the term loan was recorded net of a debt discount of $1.0 million related to fees paid under the credit agreement. Borrowings under the term loan and the revolving credit facility bore interest at a variable rate which was 5.75% in 2010 and 3.75% for most of the period in 2011 in which there were borrowings outstanding.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Other Long Term Liabilities [Abstract]
Other Long Term Liabilities	7. Other Long Term Liabilities *Deferred Revenue* We have an agreement with UCB under which UCB has the right to market Xyrem for certain indications in various countries outside the United States. We recognized contract revenues of $1.1 million during each of 2011, 2010, and 2009 related to two upfront payments received from UCB in 2006 totaling $15.0 million. In 2009, we recognized a $10.0 million milestone payment which was received from UCB in 2008. As of December 31, 2011, $9.1 million was recorded as deferred revenues related to this agreement, of which $1.1 million is a current liability. The deferred revenue balance is being recognized ratably through 2019. *Purchased Product Rights Liability* In 2007, we entered into a product license agreement with Solvay Pharmaceuticals, Inc., which was subsequently acquired by Abbott Laboratories, for the rights to market Luvox CR and Luvox in the United States which agreement was subsequently amended. Under the amended agreement we paid $4.5 million, $4.0 million and $6.0 million in 2011, 2010 and 2009, respectively, and will make our final payments totaling $4.5 million in 2012. *Liability Under Government Litigation Settlement* In 2007, we and Orphan Medical entered into agreements with a number of government entities to settle various matters associated with an investigation relating to the sale and marketing of Xyrem by Orphan Medical, which we acquired in June 2005. Under these agreements we paid $4.2 million, $3.0 million and $2.5 million in 2011, 2010 and 2009, respectively. We paid our remaining obligation of $7.3 million in January 2012.

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 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 December 31, 2011 and December 31, 2010. 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 a noncancelable operating lease for our office building located in Palo Alto, California which expires in August 2017, is renewable through 2019 and is subject to an annual rent escalation clause. We are also obligated to make payments under noncancelable operating leases for automobiles used by our sales force. Rent expense under all operating leases was as follows (in thousands):


	Year Ended December 31,
	2011		2010		2009
Rent expense	$	2,593	$	2,323	$	2,738

Future minimum lease payments under our noncancelable operating leases at December 31, 2011, were as follows (in thousands):


Year ending December 31,	Lease Payments
2012	$	1,898
2013		1,169
2014		366
2015		1
2016		—

Total	$	3,434

In February 2012, we renewed the operating lease for our Palo Alto office building and as a result, we are obligated to make additional payments of $0.5 million, $2.1 million, $2.2 million, $2.2 million, $2.3 million and $1.6 million in 2012, 2013, 2014, 2015, 2016 and 2017.

As of December 31, 2011 and 2010, we had $5.7 million and $2.1 million, respectively, of noncancelable purchase commitments under agreements with contract manufacturers, all of which were due within one year.

As of December 31, 2011, we were required to pay our investment banker a fee of $1.5 million contingent upon the completion of the merger with Azur Pharma.

Legal Proceedings

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 abbreviated new drug application, or ANDA, with the U.S. Food and Drug Administration, or FDA, requesting approval to market a generic version of Xyrem. Roxane's Paragraph IV Certification alleges that all five patents listed for Xyrem in the FDA's approved drug products with therapeutic equivalence evaluation documents, 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. We are seeking a permanent injunction to prevent Roxane from introducing a generic version of Xyrem. 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) 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. An additional 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 on May 2, 2011 to include this additional patent in response to Roxane's Paragraph IV Certification against it. We cannot predict the outcome of this matter.

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. In September 2009, we received a Paragraph IV Certification notice from Anchen Pharmaceuticals, Inc., now owned by Par Pharmaceutical Companies, Inc., or Anchen, advising that Anchen 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. Anchen's Paragraph IV Certification alleged that the Alkermes patent will not be infringed by Anchen's manufacture, use or sale of the generic product for which the ANDA was submitted and that the Alkermes patent 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, Anchen, and Anchen Incorporated, the parent of Anchen, in the United States District Court for the District of Delaware claiming infringement of the Alkermes patent by the defendants in response to the Paragraph IV Certifications filed by Actavis and Anchen. On October 14, 2009, we and Elan, as plaintiffs, also filed a lawsuit in the United States District Court for the Central District of California against Anchen claiming infringement of the Alkermes patent based upon Anchen's Paragraph IV Certification. In both cases, the plaintiffs were seeking a permanent injunction that prevented Actavis and Anchen from introducing a generic version of Luvox CR prior to the expiration of the Alkermes patent. On August 25, 2010, we and Elan entered into settlement agreements with Anchen. Under the agreements, we, Elan and Anchen agreed to dismiss all of the claims brought in the litigation without prejudice, Anchen agreed not to contest the validity or enforceability of the Alkermes patent in the United States, and we, Elan and Anchen agreed to release each other from all claims arising in the litigation or relating to the product Anchen intends to market under its ANDA. In addition, we granted a sublicense to Anchen of our rights to have manufactured, market and sell a generic version of Luvox CR in the United States. The sublicense is non-transferable, non-sublicensable and royalty-free and is exclusive even as to us and Alkermes (except with respect to Luvox CR) for a period of time. The sublicense will commence on February 15, 2013 or earlier upon the occurrence of certain events. On October 5, 2010, the United States District Court for the Central District of California dismissed the case against Elan without prejudice. On the same date, the United States District Court for the District of Delaware also dismissed the case against Anchen without prejudice. The lawsuit against Actavis is pending in the United States District Court for the District of Delaware. The court has scheduled a Markman hearing for July 24, 2012 and a pretrial conference for March 5, 2013. We cannot predict or determine the outcome of this matter. 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. Torrent's Paragraph IV Certification alleges that the Alkermes patent will not be infringed by the manufacture, use, sale or offer for sale of the generic product for which the ANDA was submitted and that the Alkermes patent is invalid. 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 by Torrent in response to Torrent's Paragraph IV Certification. We are seeking a permanent injunction that prevents Torrent from introducing a generic version of Luvox CR prior to the expiration of the 462 patent. We cannot predict the outcome of this litigation.

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.

Stock-Based Compensation

12 Months Ended

Dec. 31, 2011

Stock-Based Compensation [Abstract]

Stock-Based Compensation

10. Stock-Based Compensation

2007 Equity Incentive Plan

In 2007, our board of directors adopted, and our stockholders approved, the 2007 Equity Incentive Plan, or the 2007 Plan, which provided for the grant of incentive stock options, nonstatutory stock options, restricted stock awards, restricted stock unit awards, or RSUs, stock appreciation rights, performance stock awards and other forms of equity compensation to employees, including officers, non-employee directors and consultants. All of the grants under the 2007 Plan were granted to employees and vest ratably over service periods of three to five years and expire no more than ten years after the date of grant. As of December 31, 2011, a total of 10,022,014 shares of our common stock had been authorized for issuance under the 2007 Plan.

2007 Employee Stock Purchase Plan

In 2007, employees became eligible to participate in the ESPP. The ESPP allowed eligible employee participants to purchase shares of our common stock at a discount of 15% through payroll deductions. The ESPP consisted of a fixed offering period of 24 months with four purchase periods within each offering period. The number of shares available for issuance under our ESPP during any six month purchase period was 175,000 shares. As of December 31, 2011, a total of 1,750,000 shares of our common stock had been authorized for issuance under the ESPP.

Amended and Restated 2007 Non-Employee Directors Stock Option Plan

In 2007, our board of directors adopted, and our stockholders approved, the 2007 Non-Employee Directors Stock Option Plan, or the 2007 Directors Option Plan. The 2007 Directors Option Plan provided for the automatic grant of nonstatutory stock options to purchase shares of our common stock to our non-employee directors which vest over a period of one to three years. In addition, the 2007 Directors Option Plan provides the source of shares to fund distributions made prior to August 15, 2010 under the Directors Deferred Compensation Plan described below. As of December 31, 2011, a total of 671,463 shares of our common stock had been authorized for issuance under the 2007 Directors Option Plan.

Amended and Restated Directors Deferred Compensation Plan

In 2007, our board of directors adopted the Directors Deferred Compensation Plan, the Directors Plan. The Directors Plan allowed each non-employee director to elect to defer receipt of his or her retainer fee to a future date or dates. Amounts deferred were credited as shares of common stock to a phantom stock account the number of which were based on the amount of the retainer fees deferred divided by the market value of our common stock on the first trading day of the first open window period following the date the retainer fees were deemed earned. We recorded expense of $0.4 million, $0.2 million and $0.2 million related to retainer fees earned and deferred in 2011, 2010 and 2009, respectively. Upon termination of a director's service, the deferred shares are issued. As of December 31, 2011, 99,980 shares of common stock were unissued related to retainer fees deferred.

Stock Based Compensation

The table below shows, for all stock option grants, the weighted-average assumptions used in the Black-Scholes option pricing model and the resulting weighted-average grant date fair value of stock options granted in each of the past three years:


	Year Ended December 31,
	2011			2010			2009
Grant date fair value	$	17.38		$	7.84		$	1.34
Volatility		72	%		85	%		91	%
Expected term (years)		5.2			6.0			6.1
Range of risk-free rates		0.0-2.7	%		1.5-3.1	%		1.8-3.1	%
Expected dividend yield		0.0	%		0.0	%		0.0	%

We use a weighting of the historic volatility of a peer group, the historic volatility of our own common stock and the implied volatility of our own common stock to estimate future volatility for stock option grants and we used the implied volatility of our own common stock to estimate future volatility for grants under our ESPP. The expected term of stock options grants represents the weighted-average period the awards are expected to remain outstanding. For stock options granted in 2011, we estimated the weighted-average expected term based on historical exercise data. Prior to 2011, the expected term was estimated by assuming stock options would be exercised at the mid-point between the vest date and the contractual term. The risk-free interest rate assumption was based on zero coupon U.S. Treasury instruments whose term was consistent with the expected term of our stock option grants. The expected dividend yield assumption was based on our history and expectation of dividend payouts.

Stock-based compensation expense related to stock options, RSUs, shares of common stock credited to the directors' phantom stock accounts under the Directors Plan and grants under our ESPP was as follows (in thousands):


	Year Ended December 31,
	2011(1)		2010		2009
Selling, general and administrative	$	15,592	$	5,924	$	4,400
Research and development		4,488		2,004		1,456
Cost of product sales		624		291		101

Total stock-based compensation expense	$	20,704	$	8,219	$	5,957

(1)

Includes expense of $7.3 million related to the acceleration of vesting in December 2011 of certain non-qualified stock options held by 17 executives and non-employee directors in connection with the merger of which $6.9 million was recorded in selling, general and administrative and $0.4 million was recorded in research and development.

The following table summarizes information as of December 31, 2011 and activity during 2011, related to our stock option plans:


	Shares Subject to Outstanding Options (In thousands)			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value (In thousands)
Outstanding at January 1, 2011		5,541		$	10.39
Options granted		1,571			29.41
Options exercised		(1,419	)		9.07
Options forfeited		(185	)		15.15
Options expired		(2	)		13.33

Outstanding at December 31, 2011		5,506			16.00		6.9	$	125,793
Vested and expected to vest at December 31, 2011		5,181			15.58		6.8		120,542
Exercisable at December 31, 2011		3,647			13.69		6.1		91,951

Aggregate intrinsic value shown in the table above is equal to the difference between the exercise price of the underlying stock options and the fair value of our common stock for stock options that were in the money.

Income Taxes [Abstract]

Income Taxes

11. Income Taxes

During 2011 and 2010, we 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. Prior to 2010, we made no provision for income taxes due to our history of losses. All of our income and losses have resulted from domestic operations.

A reconciliation of income tax at the United States statutory income tax rate and our provision for income taxes is as follows (in thousands):


	December 31,
	2011			2010			2009
Income tax at federal statutory rate	$	43,744		$	11,472		$	(2,392	)
Add (deduct):
Acquisition-related costs		3,552			—			—
Research and other tax credits		(1,323	)		(380	)		(965	)
Stock-based compensation		670			1,083			1,401
Other		353			(80	)		316
Decrease in federal valuation allowance:
Utilization of federal net operating loss carryforwards		(55,271	)		(16,975	)		—
Other		8,275			4,880			1,640

Provision for income taxes	$	—		$	—		$	—

Deferred income taxes reflect the tax effects of net operating loss and tax credit carryforwards and the net temporary differences between the carrying amounts of assets and liabilities for financial reporting and the amounts used for income tax purposes. Significant components of our net deferred tax assets were as follows (in thousands):


	December 31,
	2011			2010
Deferred tax assets:
Federal and state net operating loss carryforwards	$	67,762		$	120,473
Federal and state tax credit carryforwards		15,140			14,720
Intangible assets		8,309			4,297
Stock-based compensation		6,293			2,591
Other		13,684			13,438

Total deferred tax assets		111,188			155,519
Valuation allowance		(111,188	)		(155,519	)

Net deferred tax assets	$	—		$	—

Realization of our deferred tax assets is dependent upon the generation of future taxable income, if any, the amount and timing of which are uncertain. Based on available objective evidence, management believes it more likely than not that our deferred tax assets are not recognizable and will not be recognizable until we have sufficient taxable income. Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance decreased by $44.3 million, $7.1 million, and $2.1 million in 2011, 2010 and 2009, respectively. The decreases in the valuation allowance in 2011 and 2010 were primarily due to our utilization of net operating losses.

As of December 31, 2011, we had net operating loss carryforwards and tax credit carryforwards for federal income tax purposes of approximately $197.2 million and $16.2 million, respectively, available to reduce future income subject to income taxes. The federal net operating loss carryforwards will expire, if not utilized, in the tax years 2021 to 2029, and the federal tax credits will expire, if not utilized, in the tax years 2017 to 2031. In addition, we had approximately $228.7 million of net operating loss carryforwards and $3.6 million of tax credit carryforwards as of December 31, 2011 available to reduce future taxable income for state income tax purposes. The state net operating loss carryforwards will expire, if not utilized, in the tax years 2012 to 2031. The state tax credits have no expiration date.

Approximately $35.3 million of both the federal and state net operating loss carryforwards as of December 31, 2011 resulted from exercises of employee stock options and certain sales by employees of shares issued under other employee stock programs. We have not recorded the tax benefit of the deduction related to these exercises and sales as deferred tax assets on our balance sheet. When we realize the tax benefit as a reduction to taxable income in our tax returns, we will account for the tax benefit as a credit to stockholders' equity rather than as a reduction of our income tax provision in our financial statements.

Utilization of our net operating loss carryforwards and tax credit carryforwards is subject to annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation may result in the expiration of the net operating loss before utilization. We have completed detailed reviews of our ownership changes in accordance with the Internal Revenue Code, and we have confirmed that it is more likely than not that we have not experienced an ownership change since the date of our initial Series B preferred stock funding in 2004 through December 31, 2011. However, approximately $38.0 million of net operating losses carryforwards acquired in connection with our purchase of a company in 2005 are only available ratably through 2019 and approximately $6.0 million of orphan tax credits acquired in connection with the purchase are available only from 2019 to 2024, as a result of an annual limitation due to a change in ownership of the purchased company.

We are required to recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. As a result, we have reduced our gross deferred tax assets for certain tax benefits which we judge may not be sustained upon examination, and we have provided an offset through equal reductions in our deferred tax asset valuation allowance. A reconciliation of our unrecognized tax benefits follows (in thousands):


	December 31,
	2011			2010			2009
Balance at the beginning of the year	$	4,852		$	4,711		$	4,010
Additions based on tax positions related to the current year		242			164			560
Additions for tax positions of prior years		(1,330	)		—			147
Lapse of applicable statute of limitations		—			(23	)		(6	)

Balance at the end of the year	$	3,764		$	4,852		$	4,711

There were no interest or penalties related to unrecognized tax benefits. Substantially all of the unrecognized tax benefit, if recognized, would affect our tax expense before taking our valuation allowance into consideration. We do not anticipate that the amount of existing unrecognized tax benefits will significantly increase or decrease within the next 12 months. We file income tax returns in the United States federal jurisdiction and various state jurisdictions, which typically have three tax years open at any point in time. Because of our net operating loss and tax credit carryforwards, substantially all of our tax years remain open to federal and state tax examination.

- Definition

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.

Related Party Transactions [Abstract]
Related Party Transactions	12. Related Party Transactions Long-term debt. In 2010, we repaid in full all of our then outstanding senior secured notes, of which $6.8 million principal amount was paid to an entity affiliated with Kohlberg, Kravis & Roberts & Co. L.P., or KKR, a significant stockholder. In addition, in 2010, we paid prepayment penalties and a fee to the holders of the senior secured notes totaling $8.5 million of which $484,000 was paid to the KKR affiliate. Cash paid for interest with respect to then outstanding senior secured notes held by the KKR affiliate was $461,000 and $1.3 million in 2010 and 2009, respectively. All payments to KKR were in proportion to its ownership of the senior secured notes. The exercise price of all warrants to purchase common stock issued to the holders of the then outstanding senior secured notes was reduced to $9.34 per share as a result of an amendment to the agreement governing the senior secured notes in 2009. This included warrants to purchase 70,156 shares of our common stock held by the KKR affiliate the exercise price of which was reduced from $20.36 to $9.34 per share. Common Stock Offerings. In a private placement we completed in 2009, 1,858,486 shares of common stock and a warrant to purchase 929,243 shares of common stock were acquired by Longitude Venture Partners, L.P. and 37,248 shares of common stock and a warrant to purchase 18,624 shares of common stock were acquired by Longitude Capital Associates, L.P. In July 2009, Patrick G. Enright was elected to our board of directors in connection with the closing of the private placement. Mr. Enright is a managing member of Longitude Capital Partners, LLC, the sole general partner of Longitude Venture Partners, L.P. and Longitude Capital Associates, L.P. In addition, in 2010 we issued 7,000,000 shares of our common stock in an underwritten public offering of which 821,851 shares and 16,472 shares were purchased from the underwriter by Longitude Venture Partners, L.P. and Longitude Capital Associates, L.P., respectively.

Subsequent Event	Dec. 31, 2011
Subsequent Event [Abstract]
Subsequent Event	15. Subsequent Event On January 18, 2012, pursuant to an Agreement and Plan of Merger and Reorganization, or Merger Agreement, dated as of September 19, 2011, as amended, a wholly-owned subsidiary of Jazz Pharmaceuticals plc (formerly known as Azur Pharma Public Limited Company, or Azur Pharma) merged with and into Jazz Pharmaceuticals, Inc., with Jazz Pharmaceuticals, Inc. surviving the merger and becoming a wholly-owned subsidiary of Jazz Pharmaceuticals plc. At the effective time of the merger and pursuant to the Merger Agreement, each share of the common stock, par value $0.0001 per share, of Jazz Pharmaceuticals, Inc. issued and outstanding immediately prior to the effective time of the merger was canceled and automatically converted into and became the right to receive one ordinary share, nominal value $0.0001 per share, of Jazz Pharmaceuticals plc. Further, 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. 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. Immediately prior to the merger and in order to effect the transactions contemplated by the Merger Agreement, the number of ordinary shares of Jazz Pharmaceuticals plc then outstanding were reduced based on a ratio of 0.2883 of an ordinary share of Jazz Pharmaceuticals plc for each whole ordinary share then held by the historic shareholders of Jazz Pharmaceuticals plc (such reduction, the "Azur Reorganization"). Following the Azur Reorganization and immediately after giving effect to the issuance of ordinary shares to the former stockholders of Jazz Pharmaceuticals, Inc. in the merger, approximately 43,838,000, or 78%, of the ordinary shares of Jazz Pharmaceuticals plc were held by the former stockholders of Jazz Pharmaceuticals, Inc., and the remaining approximately 12,360,000, or 22%, of the ordinary shares were held by the persons and entities who acquired ordinary shares of Jazz Pharmaceuticals plc prior to the merger. Jazz Pharmaceuticals, Inc. is treated as the acquiring company in the merger for accounting purposes, and the merger is being accounted for as a reverse acquisition under the acquisition method of accounting for business combinations. We believe the merger will result in a company with a diversified product portfolio and significantly enhanced financial and other resources which will allow us to pursue additional product growth opportunities. The merger will be accounted for using the acquisition method of accounting, with Jazz Pharmaceuticals, Inc. being treated as the accounting acquirer under U.S. GAAP. Under the acquisition method of accounting, assets and liabilities of Azur Pharma will be, as of completion of the merger, recorded at their respective fair values and added to those of Jazz Pharmaceuticals, Inc. including an amount for goodwill representing the difference between the acquisition consideration and the fair value of the identifiable net assets. Financial statements of Jazz Pharmaceuticals plc issued after the completion of the merger will include the operations of Azur Pharma beginning with the closing date, but will not be restated retroactively to include the historical financial position or results of operations of Azur Pharma for the periods prior to the closing. Following the completion of the merger, the earnings of Jazz Pharmaceuticals plc will reflect acquisition accounting adjustments, for example, amortization of identified intangible assets. Goodwill and acquired in-process research and development assets resulting from the merger will not be amortized but instead will be tested for impairment at least annually. The final determination of acquisition consideration will be determined after completion of an analysis to determine the fair values of Azur Pharma assets and liabilities. During 2011 we recognized as a component of selling, general and administrative expense, transaction costs of $11.2 million which included acquisition-related costs of $10.1 million and integration costs of $1.1 million. We are in the process of determining fair values of the assets acquired and liabilities assumed, and completing the required supplemental pro forma revenue and earnings information for this acquisition. We expect to include a preliminary determination of the acquisition consideration and detail of the assets acquired and liabilities assumed in our consolidated financial statements for the quarter ending March 31, 2012.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.

- Definition

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
