Accounting Policies [Abstract]

Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]

Accounts Receivable

As of December 31, 2018 and 2017, the Company had $78,000 and $76,000 in its allowance for doubtful accounts, respectively. The Company provides an allowance for doubtful accounts based on experience and specifically identified risks. Accounts receivable are carried at fair value and charged off against the allowance for doubtful accounts when the Company determines that recovery is unlikely and the Company ceases collection efforts.

Basis of Presentation, Policy

Basis of Presentation

The accompanying Consolidated Financial Statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).

Principles of Consolidation, Policy

Principles of Consolidation

The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation.

A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power; has the power to appoint or remove the majority of the members of the board of directors; to cast a majority of votes at the meeting of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the stockholders or equity holders.

The Company applies the guidance codified in Accounting Standard Codification (“ASC”) 810, Consolidations, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. The Company identifies an entity as a variable interest entity if either: (1) the entity does not have sufficient equity investment at risk to permit the entity to finance its activities without additional subordinated financial support, or (2) the entity’s equity investors lack the essential characteristics of a controlling financial interest. The Company performs ongoing qualitative assessments of its variable interest entities to determine whether the Company has a controlling financial interest in any variable interest entity and therefore is the primary beneficiary, and if it has the power to direct activities that impact the activities of the entity.

Management Estimates, Policy

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes to the Consolidated Financial Statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include the valuation of royalty rights - at fair value, revenue recognition and allowance for customer credits, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of share-based compensation, the recognition and measurement of current and deferred income tax assets and liabilities, and contingent consideration estimates. Actual results could differ from those estimates.

Segment Disclosures, Policy

Segment Reporting

Under ASC 280, Segment Reporting, operating segments are defined as components of an enterprise about which separate financial information is available that is regularly evaluated by the entity’s chief operating decision maker, in deciding how to allocate resources and in assessing performance. The Company has evaluated its operating segments in accordance with ASC 280 as of December 31, 2018, and has identified three reportable segments: Pharmaceutical, Medical Devices and Income Generating Assets.

Cash Equivalents and Investments, Policy

Cash Equivalents

The Company considers all highly liquid investments with initial maturities of three months or less at the date of purchase to be cash equivalents. The Company places its cash and cash equivalents with high credit quality financial institutions and, by policy, limits the amount of credit exposure in any one financial instrument.

Investment, Policy [Policy Text Block]

Investments

As of December 31, 2018, the Company’s investments comprised an investment in a privately-held company. As of December 31, 2017, the Company’s investments also included available-for-sale investments.

All marketable securities were classified as available-for-sale. Available-for-sale securities are carried at fair value, based on quoted market prices and observable inputs, with unrealized gains and losses, net of tax, reported as a separate component of stockholders’ equity. The Company classifies marketable securities that are available for use in current operations as current assets in the Consolidated Balance Sheets. Realized gains and losses and declines in value judged to be other than temporary for available-for-sale securities are included in “Interest and other income, net.” The cost of securities sold is based on the specific identification method.

On July 1, 2016, Noden Pharma DAC entered into an asset purchase agreement (“Noden Purchase Agreement”) whereby it purchased from Novartis Pharma AG (“Novartis”) the exclusive worldwide rights to manufacture, market, and sell the Noden Products and certain related assets and assumed certain related liabilities (the “Noden Transaction”). Upon the consummation of the Noden Transaction, a noncontrolling interest holder acquired a 6% equity interest in Noden. The equity interest of the noncontrolling interest holder was subject to vesting and repurchase rights over a four-year period. In May 2017, the Company repurchased this equity interest for $2.2 million in cash. The Company accounted for the repurchase in accordance with ASC 810 and recognized the difference between the fair value of the consideration paid and the amount by which the noncontrolling interest is adjusted for in equity attributable to the Company. The Company consolidates Noden under the voting interest model as of December 31, 2018 and 2017. For additional information about the consolidation of Noden, see Note 23, Business Combinations.

Fair Value Measurements, Policy

Fair Value Measurements

The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories:

Level 1 – based on quoted market prices in active markets for identical assets and liabilities;

Level 2 – based on quoted market prices for similar assets and liabilities, using observable market based inputs or unobservable market based inputs corroborated by market data, and

Level 3 – based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable.

Notes Receivable and Other Long-Term Receivables, Policy

Notes Receivable and Other Long-Term Receivables

The Company accounts for its notes receivable at amortized cost, net of unamortized origination fees, if any, and adjusted for any impairment losses. Interest is accreted or accrued to “Interest revenue” using the effective interest method. When and if supplemental payments are received from certain of these notes and other long-term receivables, an adjustment to the estimated effective interest rate is affected prospectively.

The Company evaluates the collectability of both interest and principal for each note receivable and loan to determine whether it is impaired. A note receivable or loan is considered to be impaired when, based on current information and events, the Company determines it is probable that it will be unable to collect amounts due according to the existing contractual terms. When a note receivable or loan is considered to be impaired, the amount of loss is calculated by comparing the carrying value of the financial asset to the value determined by discounting the expected future cash flows at the loan’s effective interest rate or to the estimated fair value of the underlying collateral, less costs to sell, if the loan is collateralized and the Company expects repayment to be provided solely by the collateral. Impairment assessments require significant judgments and are based on significant assumptions related to the borrower’s credit risk, financial performance, expected sales, and estimated fair value of the collateral.

The Company records interest on an accrual basis and recognizes it as earned in accordance with the contractual terms of the credit agreement, to the extent that such amounts are expected to be collected. When a note receivable or loan becomes past due, or if management otherwise does not expect that principal, interest, and other obligations due will be collected in full, the Company will generally place the note receivable or loan on an impaired status and cease recognizing interest income on that note receivable or loan on an accrual basis until all principal and interest due has been paid or until such time that the Company believes the borrower has demonstrated the ability to repay its current and future contractual obligations. Any uncollected interest related to prior periods is reversed from income in the period that collection of the interest receivable is determined to be doubtful. However, the Company may make exceptions to this policy if the investment has sufficient collateral value and is in the process of collection. Any interest payments received for notes receivable or loans on an impaired status are recognized as interest income on a cash basis.

For the years ended December 31, 2018 and 2017, the Company recognized $2.3 million and $3.1 million, respectively, of interest revenue for the CareView note receivable while on impaired status as a result of cash interest payments made during these years. For the year ended December 31, 2016, the Company did not recognize any interest income for notes receivable or loans which were impaired.

As of December 31, 2018, the Company had three notes receivable investments which were determined to be impaired with a cumulative investment cost and fair value of approximately $62.8 million and $70.0 million, respectively, compared to three note receivable investments which were determined to be impaired as of December 31, 2017 with a cumulative investment cost and fair value of approximately $70.7 million and $71.3 million, respectively. During the years ended December 31, 2018 and 2017, the Company did not recognize any losses on extinguishment of notes receivable. During the year ended December 31, 2016, the Company recognized a loss on extinguishment of notes receivable of $51.1 million.

During the year ended December 31, 2018 the Company recorded an impairment loss of $8.2 million related to the CareView note receivable. There were no impairment losses on notes receivable for the years ended December 31, 2017 and 2016. For additional information about the impairment loss recorded on the CareView note receivable, see Note 9, Notes and Other Long-Term Receivables.

Inventory, Policy [Policy Text Block]

Inventory

Inventory, which consists of raw material, work-in-process and finished goods, is stated at the lower of cost or market value. The Company determines cost using the first-in, first-out method. Inventory levels are analyzed periodically and written down to their net realizable value if they have become obsolete, have a cost basis in excess of its expected net realizable value or are in excess of expected requirements. The Company evaluates for potential excess inventory by analyzing current and future product demand relative to the remaining product shelf life. The Company builds demand forecasts by considering factors such as, but not limited to, overall market potential, market share, market acceptance and patient usage. The Company classifies inventory as current on the Consolidated Balance Sheets when the Company expects inventory to be consumed for commercial use within the next twelve months.

Intangible Assets, Finite-Lived, Policy [Policy Text Block]

Intangible Assets

Intangible assets with finite useful lives consist primarily of acquired product rights and acquired technology and are amortized on a straight-line basis over their estimated useful lives, over eight years to 15 years. The estimated useful lives associated with finite-lived intangible assets are consistent with the estimated lives of the associated products and may be modified when circumstances warrant. Such assets are reviewed for impairment when events or 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 an asset and its eventual disposition are less than its carrying amount. The amount of any impairment is measured as the difference between the carrying amount and the fair value of the impaired asset.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill

Goodwill represents the excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed. 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. The Company tests goodwill for impairment annually in December and when events or changes in circumstances indicate that the carrying value may not be recoverable. After completing the Company’s impairment review for the Noden reporting unit during the fourth quarter of 2016, the Company concluded that the goodwill of the Noden reporting unit was impaired. The Company recognized a goodwill impairment loss of $3.7 million as of December 31, 2016. There is no remaining goodwill recorded on the Consolidated Balance Sheets as of December 31, 2018 or 2017.

Property and Equipment, Policy

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the following estimated useful lives:

Leasehold improvements	Lesser of useful life or term of lease
Manufacturing equipment	3-5 years
Computer and office equipment	3 years
Transportation equipment	3 years
Furniture and fixtures	7 years
Equipment under lease	Greater of lease term or 5-10 years

Debt, Policy [Policy Text Block]

Convertible Notes

The Company issued the December 2021 Notes with a settlement feature that allows the Company to settle the notes by paying or delivering, as applicable, cash, shares of the Company’s common stock or a combination of cash and shares of our common stock, at the Company’s election. In accordance with accounting guidance for convertible debt instruments that may be settled in cash or other assets on conversion, the Company separated the principal balance between the fair value of the liability component and the common stock conversion feature using a market interest rate for a similar nonconvertible instrument at the date of issuance.

Financing Costs Related to Long-term Debt [Policy Text Block]

Financing Costs Related to Long-term Debt

Costs associated with obtaining long-term debt are deferred and amortized over the term of the related debt using the effective interest method. Such costs are presented as reductions from the carrying amount of the long-term debt liability, consistent with debt discounts, on the Company’s Consolidated Balance Sheets.

Product Revenue, Policy

Revenue Recognition

Adoption of New Revenue Recognition Standard

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers that supersedes Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition (“ASC 605”). Subsequently, the FASB issued several updates to ASU No. 2014-09, codified in ASC Topic 606 (“ASC 606”). ASC 606 also includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40. The Company adopted ASC 606 on January 1, 2018 using the modified retrospective method for all contracts not substantially completed as of the date of adoption. The cumulative impact of the adoption of ASC 606 was not material to the Company; therefore, the Company did not record any adjustments to retained earnings. The reported results for 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, which is also referred to herein as “legacy GAAP” or the “previous guidance”.

Policy Elections and Practical Expedients Taken

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.

Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of product revenue.

Sales commissions and other incremental costs of obtaining contracts are expensed as incurred as the amortization periods are less than one year.

General

In accordance with ASC 606, revenue is recognized from the sale of products when a customer obtains control of promised products and services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these products and services. A five-step model is utilized to achieve the core principle and includes the following steps: (1) identify the customer contract; (2) identify the contract’s performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when the performance obligations are satisfied.

The following is a description of principal activities - separated by reportable segments - from which the Company generates its revenue. For more detailed information about reportable segments, see Note 24, Segment Information.

Pharmaceutical

The Pharmaceutical segment of the Company principally generates revenue from products sold to wholesalers and distributors. Customer orders are generally fulfilled within a few days of receipt resulting in minimal order backlog. Contractual performance obligations are usually limited to transfer of the product to the customer. The transfer occurs either upon shipment or upon receipt of the product in certain countries outside the United States after considering when the customer obtains control of the product. In addition, for some non-U.S. countries, the Company sells product on a consignment basis where control is not transferred until the customer resells the product to an end user. At these points, customers are able to direct the use of and obtain substantially all of the remaining benefits of the product.

Sales to customers are initially invoiced at contractual list prices. Payment terms are typically 30 to 90 days based on customary practice in each country. Revenue is reduced from the list price at the time of recognition for expected chargebacks, discounts, rebates, sales allowances and product returns, which are referred to as gross-to-net adjustments. A description of gross-to-net adjustments are described below.

Customer Credits: The Company’s customers are offered various forms of consideration, including allowances, service fees and prompt payment discounts. The Company expects the customers will earn prompt payment discounts and, therefore, the Company deducts the full amount of these discounts from total product sales when revenues are recognized. Service fees are also deducted from total product sales as they are earned.

Rebates and Discounts: Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program in the United States and mandated discounts in the European Union in markets where government-sponsored healthcare systems are the primary payers for healthcare. Rebates are amounts owed after the final dispensing of the product to a benefit plan participant and are based upon contractual agreements or legal requirements with public sector benefit providers. The accrual for rebates is based on negotiated discount rates and expected utilization as well as historical data. Estimates for expected utilization of rebates are based on data received from the customers. Rebates are generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for known prior quarters’ unpaid rebates. If actual future rebates vary from estimates, the Company may need to adjust prior period accruals, which would affect revenue in the period of adjustment.

Chargebacks: Chargebacks are discounts that occur when certain contracted customers, which currently consist primarily of group purchasing organizations, Public Health Service institutions, non-profit clinics, and Federal government entities purchasing via the Federal Supply Schedule, purchase directly from the Company’s wholesalers. Contracted customers generally purchase the product at a discounted price. The wholesalers, in turn, charges back to the Company the difference between the price initially paid by the wholesalers and the discounted price paid by the contracted customers. In addition to actual chargebacks received, the Company maintains an accrual for chargebacks based on the estimated contractual discounts on products sold for which the chargeback has not been billed. If actual future chargebacks vary from these estimates, the Company may need to adjust prior period accruals, which would affect revenue in the period of adjustment.

Medicare Part D Coverage Gap: Medicare Part D prescription drug benefit mandates manufacturers to fund 50% of the Medicare Part D insurance coverage gap for prescription drugs sold to eligible patients. Estimates for the expected Medicare Part D coverage gap are based on historical invoices received and in part from data received from the Company’s customers. Funding of the coverage gap is generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for known prior quarters. If actual future funding varies from estimates, the Company may need to adjust prior period accruals, which would affect revenue in the period of adjustment.

Co-payment Assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive co-payment assistance. The Company accrues a liability for co-payment assistance based on actual program participation and estimates of program redemption using data provided by third-party administrators.

Returns: Returns are generally estimated and recorded based on historical sales and returns information. Products that exhibit unusual sales or return patterns due to dating, competition or other marketing matters are specifically investigated and analyzed as part of the accounting for sales returns accruals.

Reserves for chargebacks, discounts, rebates, sales allowances and product returns are included within current liabilities in the Company’s Consolidated Balance Sheets.

For the period from July 1, 2016 through October 4, 2016, all of the Noden Products were distributed by Novartis under the terms of the Noden Purchase Agreement while transfer of the marketing authorization rights were pending. The Company presents revenue under the Novartis transition arrangement on a “net” basis and established a reserve for retroactive adjustment to the profit transfer with Novartis.

Beginning on October 5, 2016, Noden Pharma USA, Inc. distributed the Noden Products in the United States. The Company presented revenue for all sales in the United States on a “gross” basis and established a reserve for allowances.

For the period from October 5, 2016 to August 31, 2017, Novartis continued to distribute the Noden products outside of the United States. Beginning on September 1, 2017, Noden Pharma DAC began distributing the Noden Products to select countries outside the United States. The Company presents revenue for Noden Products sold by Novartis outside of the United States on a “net” basis. As of the third quarter of 2018, Noden Pharma DAC completed the marketing authorization transfers for all territories.

For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front license fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Medical Devices

The Medical Devices segment of the Company principally generates revenue from the sale and lease of the LENSAR^® Laser System, which may include equipment, Patient Interface Devices (“PIDs”), procedure licenses, and training, installation, warranty and maintenance agreements.

For bundled packages, the Company accounts for individual products and services separately if they are distinct - i.e. if a product or service is separately identifiable from other items in the bundled package and if the customer can benefit from it on its own or with other resources that are readily available to the customer. The LENSAR® Laser system, standard warranty training and installation services are one performance obligation. All other elements are separate performance obligations. PIDs, procedure licenses, warranty and maintenance services are also sold on a stand-alone basis.

As the Company both sells and leases the LENSAR^® Laser System, the consideration (including any discounts) is first allocated between lease and non-lease components and then allocated between the separate products and services based on their stand-alone selling prices. The stand-alone selling prices for the PIDs and procedure licenses are determined based on the prices at which the Company separately sells the PIDs and procedure licenses. The LENSAR^® Laser System and warranty stand-alone selling prices are determined using the expected cost plus a margin approach.

For LENSAR^® Laser System sales, the Company recognizes revenue in product revenue when a customer takes possession of the system. This usually occurs after the customer signs a contract, LENSAR installs the system, and LENSAR performs the requisite training for use of the system. For LENSAR^® Laser System leases, the Company recognizes revenue in product revenue over the length of the lease in accordance with ASC Topic 840, Leases.

The LENSAR^® Laser System requires both a consumable, a PID, and a procedure license to perform each procedure. The Company recognizes revenue for PIDs in product revenue when the customer takes possession of the PID. PIDs are sold by the case. The Company recognizes revenue for procedure licenses in product revenue when a customer purchases a procedure license from the web portal. Typically, consideration for PIDs and procedure licenses is considered fixed consideration except for certain customer agreements that provide for tiered volume discount pricing which is considered variable consideration.

The Company offers an extended warranty that provides additional services beyond the standard warranty. The Company recognizes revenue from the sale of extended warranties in product revenue over the warranty period. Customers have the option of renewing the warranty period, which is considered a new and separate contract.

Income Generating Assets

Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license.

In January 2018, DFM, LLC, a wholly-owned subsidiary of the Company, granted an exclusive license related to certain Direct Flow Medical assets in exchange for $0.5 million in cash and up to $2.0 million in royalty payments. The $0.5 million payment was accounted for in accordance with ASC 606 under which the full cash payment was recognized as revenue in the first quarter of 2018 as DFM, LLC had fulfilled its performance obligation under the agreement.

Queen et al. Royalty Revenues [Policy Text Block]

Queen et al. Royalty Revenues

Under the Company’s license agreements related to patents covering the humanization of antibodies, which it refers to as the Queen et al. patents, the Company receives royalty payments based upon its licensees’ net sales of covered products. Royalties qualify for the sales-and-usage exemption under ASC 606 as (i) royalties are based strictly on the sales-and-usage by the licensee; and (ii) a license of intellectual property is the sole or predominant item to which such royalties relate. Based on this exemption, these royalties are earned under the terms of a license agreement in the period the products are sold by the Company's partner and the Company has a present right to payment. Generally, under these agreements, the Company receives royalty reports from its licensees approximately one quarter in arrears; that is, generally in the second month of the quarter after the licensee has sold the royalty-bearing product. The Company recognizes royalty revenues when it can reliably estimate such amounts and collectability is reasonably assured. Under this accounting policy, the royalty revenues the Company reports are not based upon estimates, and such royalty revenues are typically reported in the same period in which the Company receives payment from its licensees.

Although the last of the Queen et al. patents expired in December 2014, the Company has received royalties beyond expiration based on the terms of its licenses and its legal settlement. Under the terms of the legal settlement between Genentech, Inc. (“Genentech”) and the Company, the first quarter of 2016 was the last period for which Genentech paid royalties to the Company for Avastin^®, Herceptin^®, Xolair^®, Perjeta^® and Kadcyla^®. Other products from the Queen et al. patent licenses, such as Tysabri^®, entitle the Company to royalties following the expiration of its patents with respect to sales of licensed product manufactured prior to patent expiry in jurisdictions providing patent protection licenses. In November 2017, the Company was notified by Biogen, Inc. that product supply for Tysabri^® that was manufactured prior to patent expiry, and for which the Company would receive royalties on, had been extinguished in the United States and was rapidly being reduced in other countries. As a result, royalties from product sales of Tysabri were substantially lower in 2018 and no additional royalties are expected.

Acquired Royalty Rights, Policy

Royalty Rights - At Fair Value

Currently, the Company accounts for its investments in royalty rights at fair value with changes in fair value presented in earnings. The fair value of the investments in royalty rights is determined by using a discounted cash flow analysis related to the expected future cash flows to be received. These assets are classified as Level 3 assets within the fair value hierarchy, as the Company’s valuation estimates utilize significant unobservable inputs, including estimates as to the probability and timing of future sales of the related products. Transaction-related fees and costs are expensed as incurred.

The changes in the estimated fair value from investments in royalty rights along with cash receipts in each reporting period are presented together on the Company’s Consolidated Statements of Operations as a component of revenue under the caption, “Royalty rights - change in fair value.”

Realized gains and losses on royalty rights are recognized as they are earned and when collection is reasonably assured. Royalty Rights revenue is recognized over the respective contractual arrangement period. Critical estimates may include product demand and market growth assumptions, inventory target levels, product approval, pricing assumptions and the impact of competition from other branded or generic products. Factors that could cause a change in estimates of future cash flows include a change in estimated market size, a change in pricing strategy or reimbursement coverage, a delay in obtaining regulatory approval, a change in dosage of the product a change in the number of treatments and the entrants of new competitors or generic products. For each arrangement, the Company is entitled to royalty payments based on revenue generated by the net sales of the product.

Derivatives, Methods of Accounting, Hedge Documentation [Policy Text Block]

Foreign Currency Hedging

From time to time, the Company may enter into foreign currency hedges to manage exposures arising in the normal course of business and not for speculative purposes.

The Company hedged certain Euro-denominated currency exposures related to royalties associated with its licensees’ product sales with Euro forward contracts. In general, those contracts were intended to offset the underlying Euro market risk in the Company’s royalty revenues. The last of those contracts expired in the fourth quarter of 2015 and was settled in the first quarter of 2016. The Company designated foreign currency exchange contracts used to hedge royalty revenues based on underlying Euro-denominated licensee product sales as cash flow hedges.

The fair value of the Euro forward contracts was estimated using pricing models with readily observable inputs from actively quoted markets and was disclosed on a gross basis. The aggregate unrealized gains or losses, net of tax, on the effective component of the hedge was recorded in stockholders’ equity as “Accumulated other comprehensive income.” Realized gains or losses on cash flow hedges are recognized as an adjustment to royalty revenue in the same period that the hedged transaction impacts earnings as royalty revenue. Any gain or loss on the ineffective portion of these hedge contracts is reported in “Interest and other income, net” in the period the ineffectiveness occurs.

Foreign Currency Hedging, Policy

Foreign Currency Translation

The Company uses the U.S. dollar predominately as the functional currency of its foreign subsidiaries. For foreign subsidiaries where the U.S. dollar is the functional currency, gains and losses from remeasurement of foreign currency balances into U.S. dollars are included in the Consolidated Statements of Operations. The aggregate net gains (losses) resulting from foreign currency transactions and remeasurement of foreign currency balances into U.S. dollars that were included in the Consolidated Statements of Operations amounted to a $0.7 million loss, $0.1 million gain and less than $0.1 million gain for the years ended December 31, 2018, 2017 and 2016, respectively.

Comprehensive Income, Policy

Comprehensive (Loss) Income

Comprehensive (loss) income comprises net (loss) income adjusted for other comprehensive (loss) income, using the specific identification method, which includes the changes in unrealized gains and losses on cash flow hedges and changes in unrealized gains and losses on the Company’s investments in available-for-sale securities, all net of tax, which are excluded from the Company’s net (loss) income.

Income Tax, Policy [Policy Text Block]

Income Taxes

The provision for income taxes is determined using the asset and liability approach. Tax laws require items to be included in tax filings at different times than the items are reflected in the Consolidated Financial Statements. A current liability is recognized for the estimated taxes payable for the current year. Deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. Deferred taxes are adjusted for enacted changes in tax rates and tax laws. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Any interest and penalties on uncertain tax positions are included within the tax provision.

The Tax Cuts and Job Act of 2017 (the “2017 Tax Act”) significantly changed the existing U.S. corporate income tax laws by, among other things, lowering the corporate tax rate (from a top rate of 35% to a flat rate of 21%), implementing elements of a territorial tax system, and imposing a one-time deemed repatriation transition tax on cumulative undistributed foreign earnings, for which we have not previously paid U.S. taxes. The Company recognized the estimated tax impact related to the revaluation of deferred tax assets and liabilities in its Consolidated Financial Statements for the year ended December 31, 2017. The ultimate impact did not differ materially from these provisional amounts after additional analysis, changes in interpretations and assumptions the Company made and additional regulatory guidance that was issued. The accounting was completed when the Company’s 2017 U.S. corporate income tax return was filed in 2018. The Company has made a policy election with respect to its treatment of potential global intangible low-taxed income (“GILTI”) to account for taxes on GILTI as a current-period expense as incurred.

Business Combinations Policy [Policy Text Block]

Business Combination

The Company applies ASC 805, Business combinations (“ASC 805”), pursuant to which the cost of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of the (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree is recorded as goodwill. If the cost of an acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in the Consolidated Statements of Operations as a bargain purchase gain.

Lease, Policy [Policy Text Block] (Deprecated 2017-01-31)

Lease Accounting and Lease Guarantee

The Company accounts for operating leases by recording rent expense on a straight-line basis over the expected life of the lease, commencing on the date the Company gains possession of leased property. The Company includes tenant improvement allowances and rent holidays received from landlords and the effect of any rent escalation clauses as adjustments to straight-line rent expense over the expected life of the lease.

Capital leases are reflected as a liability at the inception of the lease based on the present value of the minimum lease payments or, if lower, the fair value of the property. Assets under capital leases are recorded in property and equipment, net on the Company’s Consolidated Balance Sheets and depreciated in a manner consistent with other property and equipment.

New Accounting Pronouncements, Policy [Policy Text Block]

Adopted Accounting Pronouncements

In October 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The new standard requires equity securities (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income. Under the previous guidance, changes in the fair value of equity securities were recognized through other comprehensive income. Effective January 1, 2018, the Company adopted the requirements of ASU No. 2016-01. The adoption did not have an effect on the Consolidated Financial Statements on the adoption date and no adjustment to prior year Consolidated Financial Statements was required.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. The new standard provides for specific guidance how certain transactions are classified in the statement of cash flows. Effective January 1, 2018, the Company adopted the requirements of ASU No. 2016-15. The adoption did not have an effect on the Consolidated Financial Statements on the adoption date and no adjustment to prior year Consolidated Financial Statements was required.

In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory in the period in which the transfer occurs. Effective January 1, 2018, the Company adopted the requirements of ASU No. 2016-16. The adoption did not have an effect on the Consolidated Financial Statements on the adoption date and no adjustment to prior year Consolidated Financial Statements was required.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, which requires entities to show the changes in total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. Effective January 1, 2018, the Company adopted the requirements of ASU No. 2016-18. The adoption did not have an effect on the Consolidated Financial Statements on the adoption date and no adjustment to prior year Consolidated Financial Statements was required.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases, which outlines a comprehensive lease accounting model that supersedes the current lease guidance and requires lessees to recognize lease liabilities and corresponding right-of-use assets for all leases with lease terms greater than 12 months. The guidance also changes the definition of a lease and expands the disclosure requirements of lease arrangements. The new standard is to be applied using either a modified retrospective approach, or an optional transition method that allows an entity to apply the new standard at the adoption date with a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption and will be effective for the Company starting with the first quarter of 2019, with early adoption permitted. Effective the first quarter of 2019, the Company will adopt the standard, using a modified retrospective approach. The Company does not expect the adoption will have a material impact on its consolidated statement of earnings. However, the new standard will require the Company to establish liabilities and corresponding right-of-use assets on its Consolidated Balance Sheet for operating leases that exist as of the January 1, 2019 adoption date.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The new guidance amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses. ASU No. 2016-13 has an effective date of the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating ASU No. 2016-13 and assessing the impact, if any, it may have to the Company’s Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. Under the amendments, an entity will recognize an impairment charge for the amount by which the carrying value exceeds the fair value. The amendments are effective for fiscal years and interim periods within those years beginning after December 15, 2019 on a prospective basis and early adoption is permitted. The Company is currently evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement. The new guidance modifies disclosure requirements related to fair value measurement. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. The standard also allows for early adoption of any removed or modified disclosures upon issuance of this ASU while delaying adoption of the additional disclosures until their effective date.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software: Customer’s Accounting for Implementation costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new guidance reduces complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The new guidance will become effective for the Company on January 1, 2020. Early adoption is permitted. Implementation should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently evaluating the impact the adoption of this guidance will have on its Consolidated Financial Statements.
