Description of Operations and Summary of Significant Accounting Policies (Policies)	9 Months Ended
Sep. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and, in our opinion, include all adjustments, consisting of all normal recurring adjustments, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows. The interim results are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2022 or any other periods. The accompanying unaudited condensed consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries, and certain variable interest entities (“VIEs”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. For consolidated entities where we own or are exposed to less than 100% of the economics, we record net income attributable to noncontrolling interest in our unaudited condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”) on February 28, 2022, and as amended on March 17, 2022. Factors Affecting Comparability Our historical financial condition and results of operations for the periods presented may not be comparable, either between periods or going forward due to the factors below and as discussed in Note 5, “Consolidated Entities and Acquisitions”. • Accounting consolidation of Entasis on February 17, 2022 and purchase of remaining minority interest in Entasis on July 11, 2022, • Sale of our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and • Acquisition of La Jolla on August 22, 2022.
Factors Affecting Comparability	Factors Affecting Comparability Our historical financial condition and results of operations for the periods presented may not be comparable, either between periods or going forward due to the factors below and as discussed in Note 5, “Consolidated Entities and Acquisitions”. • Accounting consolidation of Entasis on February 17, 2022 and purchase of remaining minority interest in Entasis on July 11, 2022, • Sale of our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and • Acquisition of La Jolla on August 22, 2022.
Prior Period Immaterial Correction	Prior Period Immaterial Correction Subsequent to the issuance of the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2021, the Company identified that (i) purchases of equity investments managed by ISP Fund LP for $178.4 million, (ii) sales of equity investments managed by ISP Fund LP for $21.4 million, and (iii) purchase and sales of other investments managed by ISP Fund LP, net for $267.0 million were incorrectly included in the unaudited condensed consolidated statement of cash flows within the distribution of equity and long-term investments line item. The Company has corrected the presentation in the accompanying unaudited condensed consolidated statement of cash flows for the nine months ended September 30, 2021 from amounts previously reported to present such line items separately. The correction did not impact total cash flows from investing activities or the unaudited condensed consolidated balance sheet, statement of income, or statement of comprehensive income for the relevant period. Management assessed the correction on a quantitative and qualitative basis and determined that it is immaterial to the prior period unaudited condensed consolidated financial statements.
Use of Management's Estimates	Use of Management’s Estimates The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Management evaluates its significant accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. These estimates also form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.
Concentrations of Credit Risk and of Significant Suppliers and Partner	Concentrations of Credit Risk and of Significant Suppliers and Partner Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, equity and long-term investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed federally insured limits. We are dependent on third-party manufacturers to supply active pharmaceutical ingredients (“API”) and drug products for research and development and commercial programs. These programs could be adversely affected by significant interruption in the supply of API or drug products. Currently, we derive most of our revenues from GSK and our near-term success depends in large part on GSK’s ability to successfully develop and commercialize the products in the respiratory programs partnered with GSK. Our near-term success depends in large part upon the performance by GSK of its commercial obligations under the GSK Agreements and the commercial success of RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. If GSK does not devote sufficient resources to the commercialization or development of these products, is unsuccessful in its efforts, or chooses to reprioritize its commercial programs, our business would be materially harmed. GSK is responsible for all clinical and other product development, regulatory, manufacturing and commercialization activities for products developed under the GSK Agreements, including RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. Our quarterly royalty revenues may fluctuate due to a variety of factors, many of which are outside of our control. Our royalty revenues under the GSK Agreements may not meet our, analysts’ or investors’ expectations, due to a number of important factors. We also started recognizing revenue from product sales as a result of our acquisition of La Jolla. Hospitals and other healthcare organizations generally purchase our products through a network of specialty distributors. These specialty distributors, which are located in the U.S., are considered our customers for accounting purposes. We do not believe that loss of one of these distributors would significantly impact our ability to distribute our products, as we expect that sales volume would be absorbed by new or remaining distributors. Three of our customers each comprise 10% or more of our net product sales and they account for 32%, 32% and 29%, respectively, of our net product sales from the time of La Jolla’s acquisition to September 30, 2022. These same customers account for 34%, 23% and 35%, respectively, of our receivables from net product sales, which is included in “Accounts receivables, net” in our unaudited consolidated balance sheet as of September 30, 2022. Refer to Item 1A. “Risk Factors” disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021 and to the supplemental risk factors detailed in our Form 8-K filed on August 23, 2022 for further detail.
Segment Reporting	Segment Reporting We operate in a single segment, which is to provide capital return to stockholders by maximizing the potential value of our portfolio of royalties and innovative healthcare assets. Our Chief Operating Decision Maker (“CODM”) is our Chief Executive Officer. The CODM allocates resources and evaluates the performance of Innoviva at the consolidated level using information about our revenues, operating results and other key financial data as needed. Our revenues are generated primarily from our collaborative arrangements and royalty payments from GSK, located in Great Britain. We also generate revenue from net sales of GIAPREZA® and XERAVA®. Our long-term assets are located within the United States.
Variable Interest Entities	Variable Interest Entities We evaluate our ownership, contractual and other interest in entities to determine if they are a VIE. We evaluate whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluation, if we determine we are the primary beneficiary of a VIE, we consolidate the entity in our financial statements.
Business Combination	Business Combination When we acquire an entity in a business combination, we recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establish the acquisition date as the fair value measurement point. We recognize and measure goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. Acquisition-related expenses and related restructuring costs are expensed as incurred. Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use the income method. This method starts with a forecast of all of the expected future net cash flows for each asset. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. Determining the useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments purchased with a maturity of three months or less on the date of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable, net are recorded net of estimates for prompt-pay discounts, chargebacks, returns, rebates, and administrative fees. Allowances for prompt-pay discounts and chargebacks are based on contractual terms. We estimate the allowance for credit losses based on existing contractual payment terms, actual payment patterns of customers and individual customer circumstances.
Inventory	Inventory Inventory is stated at the lower of cost or estimated net realizable value on a first in, first out basis. We periodically analyze inventory levels and write down inventory as cost of products sold when the following occurs: inventory has become obsolete, inventory has a cost basis in excess of its estimated net realizable value, or inventory quantities are in excess of expected product sales.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is recognized as the excess of the purchase consideration of an acquired entity over the fair value assigned to assets acquired and liabilities assumed in a business combination. Goodwill and intangible assets with indefinite lives are subject to impairment testing at least annually or more frequently if indicators for potential impairment exist. Intangible assets with definite lives are amortized on a straight-line basis over the remaining useful life of the intangible asset. These assets are tested for impairment whenever events or changes in circumstances indicate that an asset’s carrying amount may not be recoverable. Significant judgments are involved in determining if an indicator of impairment has occurred.
Operating Leases	Operating Leases We account for our leases under ASC 842, Leases. Right-of-use assets represent our right to use an underlying asset over the lease term and include any lease payments made prior to the lease commencement date and are reduced by lease incentives. Lease liabilities represent the present value of the total lease payments over the lease term, calculated using an estimated incremental borrowing rate. Lease expense is recognized on a straight-line basis over the expected lease term.
Equity and Long-Term Investments	Equity and Long-Term Investments We invest from time to time in equity and debt securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we consolidate them in our unaudited condensed consolidated financial statements. If we determine that we do not have control over these companies under either voting or VIE models, we then determine if we have an ability to exercise significant influence via voting interests, board representation or other business relationships. We may account for the investments where we exercise significant influence using either an equity method of accounting or at fair value by electing the fair value option. If the fair value option is applied to an investment that would otherwise be accounted for under the equity method, we apply it to all our financial interests in the same entity (equity and debt, including guarantees) that are eligible items. All gains and losses from fair value changes, unrealized and realized, are presented as changes in fair values of equity and long-term investments, net within the unaudited condensed consolidated statements of income. If we conclude that we do not have an ability to exercise significant influence over an investee, we may elect to account for the security without a readily determinable fair value using the measurement alternative method under ASC 321, Investments - Equity Securities. This measurement alternative method allows us to measure the equity investment at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We also invest in ISP Fund LP, which investments consist of money market funds and equity and debt securities in the healthcare, pharmaceutical and biotechnology industries. Pursuant to the Partnership Agreement entered in December 2020, we became a limited partner of this partnership, and our contributions are subject to a 36-month lock-up period which prevents us from having control and access to the contributions and related investments. These investments are classified as long-term investments on the unaudited condensed consolidated balance sheets.
Revenue Recognition	Revenue Recognition Revenue is recognized when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. Revenue is recognized through a five-step process: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price for the contract; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue as a performance obligation is satisfied. Royalty Revenue from Collaboration Arrangement We recognize the royalty revenue on net sales of products with respect to which we have contractual royalty rights in the period in which the royalties are earned. The net sales reports provided by our partner are based on its methodology and assumptions to estimate rebates and returns, which it monitors and adjusts regularly in light of contractual and legal obligations, historical trends, past experience and projected market conditions. Our partner may make significant adjustments to its sales based on actual results recorded, which could cause our royalty revenue to fluctuate. We conduct periodic royalty audits to evaluate the information provided by our partner. Royalties are recognized net of amortization of capitalized fees associated with any approval and launch milestone payments made to GSK. Revenue from Product Sales Revenue from product sales is recognized when our customers obtain control of the product and is recorded at the transaction price, net of estimates for variable consideration consisting of chargebacks, discounts, returns, rebates and administrative fees. Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. Actual amounts of consideration ultimately received may differ from our estimates. If actual results vary materially from our estimates, we will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. These items may include: • Chargebacks: Chargebacks are discounts we provide to distributors in the event that the sales prices to end users are below the distributors’ acquisition price. This may occur due to a direct contract with a health system, a group purchasing organization (“GPO”) agreement or a sale to a government facility. Chargebacks are estimated based on known chargeback rates and recorded as a reduction of revenue on delivery to our customers. • Discounts: We offer customers various forms of incentives and consideration, including prompt-pay and other discounts. We estimate discounts primarily based on contractual terms. These discounts are recorded as a reduction of revenue on delivery to our customers. • Returns: We offer customers a limited right of return, generally for damaged or expired product. We estimate returns based on an internal analysis, which includes actual experience. The estimates for returns are recorded as a reduction of revenue on delivery to our customers. • Rebates: We participate in Medicaid rebate programs, which provide assistance to certain low-income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, we pay a rebate to each participating state, generally within three months after the quarter in which product was sold. Additionally, we may offer customer incentives and consideration in the form of volume-based or other rebates. The estimates for rebates are recorded as a reduction of revenue on delivery to our customers. • Administrative Fees: We pay administrative fees to GPOs for services and access to data. Additionally, we pay an Industrial Funding Fee as part of the U.S. General Services Administration’s Federal Supply Schedules program. These fees are based on contracted terms and are paid after the quarter in which the product was purchased by the applicable GPO or government agency. Administrative fees are recorded as a reduction of revenue on delivery to customers. We continue to assess our estimates of variable consideration as we accumulate additional historical data and will adjust these estimates accordingly.
Research and Development Costs	Research and Development Costs Research and development costs are expensed in the period that services are rendered or goods are received. Research and development costs consist of salaries and benefits, laboratory supplies, facilities and other overhead costs, research-related manufacturing costs, contract service and clinical-related service costs performed by third party research organizations, research institutions and other outside service providers. Non-refundable prepayments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as an expense as the related goods are delivered or the related services are performed. We also utilize significant judgment and estimates to record accruals for estimated ongoing research costs based on the progress of the studies and progress of research manufacturing activities.
Interest Expense on Deferred Royalty Obligation	Interest Expense on Deferred Royalty Obligation Interest expense related to the deferred royalty obligation is recognized over the expected repayment term of the deferred royalty obligation using the effective interest method. The assumptions used in determining the expected repayment term of the deferred royalty obligation require us to make estimates that could impact the effective interest rate. Each reporting period, we estimate the expected repayment term of the deferred royalty obligation based on forecasted net sales of GIAPREZA®. Changes in interest expense resulting from changes in the effective interest rate, if any, are recorded on a prospective basis. Refer to Note 6, “Financial Instruments and Fair Value Measurements” for more information.
Accounting Pronouncement Adopted by the Company	Accounting Pronouncement Adopted by the Company In August 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20 for convertible instruments. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new standard also requires the if-converted method to be used to calculate diluted earnings per share (“EPS”) for convertible instruments. Effective January 1, 2022, we adopted the new standard using the modified retrospective approach and assessed the effect of this adoption on the accounting for our outstanding convertible notes. The effect of the adoption on our 2025 Notes (as defined below) resulted in a decrease to the opening balance of accumulated deficit of $37.2 million, a reduction to additional paid-in capital of $65.4 million, an increase to the balance of the notes by an aggregate amount of $35.6 million, and an increase to deferred tax assets of $7.4 million. The dilutive EPS of our 2025 Notes will be computed under the if-converted method going forward. There was no financial impact from the implementation of the standard for our 2023 Notes (as defined below). Refer to Note 10, “Debt” for more information. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities (i.e., deferred revenue) acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. During the third quarter of 2022, we elected to early adopt ASU 2021-08 effective July 1, 2022. The adoption did not have a material impact on our unaudited, condensed consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and, in our opinion, include all adjustments, consisting of all normal recurring adjustments, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows. The interim results are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2022 or any other periods.

The accompanying unaudited condensed consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries, and certain variable interest entities (“VIEs”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. For consolidated entities where we own or are exposed to less than 100% of the economics, we record net income attributable to noncontrolling interest in our unaudited condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”) on February 28, 2022, and as amended on March 17, 2022.

Factors Affecting Comparability

Our historical financial condition and results of operations for the periods presented may not be comparable, either between periods or going forward due to the factors below and as discussed in Note 5, “Consolidated Entities and Acquisitions”.

Prior Period Immaterial Correction

Subsequent to the issuance of the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2021, the Company identified that (i) purchases of equity investments managed by ISP Fund LP for $178.4 million, (ii) sales of equity investments managed by ISP Fund LP for $21.4 million, and (iii) purchase and sales of other investments managed by ISP Fund LP, net for $267.0 million were incorrectly included in the unaudited condensed consolidated statement of cash flows within the distribution of equity and long-term investments line item. The Company has corrected the presentation in the accompanying unaudited condensed consolidated statement of cash flows for the nine months ended September 30, 2021 from amounts previously reported to present such line items separately. The correction did not impact total cash flows from investing activities or the unaudited condensed consolidated balance sheet, statement of income, or statement of comprehensive income for the relevant period. Management assessed the correction on a quantitative and qualitative basis and determined that it is immaterial to the prior period unaudited condensed consolidated financial statements.

Use of Management's Estimates

Use of Management’s Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Management evaluates its significant accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. These estimates also form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

Concentrations of Credit Risk and of Significant Suppliers and Partner

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, equity and long-term investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed federally insured limits.

We are dependent on third-party manufacturers to supply active pharmaceutical ingredients (“API”) and drug products for research and development and commercial programs. These programs could be adversely affected by significant interruption in the supply of API or drug products.

Currently, we derive most of our revenues from GSK and our near-term success depends in large part on GSK’s ability to successfully develop and commercialize the products in the respiratory programs partnered with GSK. Our near-term success depends in large part upon the performance by GSK of its commercial obligations under the GSK Agreements and the commercial success of RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. If GSK does not devote sufficient resources to the commercialization or development of these products, is unsuccessful in its efforts, or chooses to reprioritize its commercial programs, our business would be materially harmed. GSK is responsible for all clinical and other product development, regulatory, manufacturing and commercialization activities for products developed under the GSK Agreements, including RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. Our quarterly royalty revenues may fluctuate due to a variety of factors, many of which are outside of our control. Our royalty revenues under the GSK Agreements may not meet our, analysts’ or investors’ expectations, due to a number of important factors.

We also started recognizing revenue from product sales as a result of our acquisition of La Jolla. Hospitals and other healthcare organizations generally purchase our products through a network of specialty distributors. These specialty distributors, which are located in the U.S., are considered our customers for accounting purposes. We do not believe that loss of one of these distributors would significantly impact our ability to distribute our products, as we expect that sales volume would be absorbed by new or remaining distributors. Three of our customers each comprise 10% or more of our net product sales and they account for 32%, 32% and 29%, respectively, of our net product sales from the time of La Jolla’s acquisition to September 30, 2022. These same customers account for 34%, 23% and 35%, respectively, of our receivables from net product sales, which is included in “Accounts receivables, net” in our unaudited consolidated balance sheet as of September 30, 2022.

Refer to Item 1A. “Risk Factors” disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021 and to the supplemental risk factors detailed in our Form 8-K filed on August 23, 2022 for further detail.

Segment Reporting

We operate in a single segment, which is to provide capital return to stockholders by maximizing the potential value of our portfolio of royalties and innovative healthcare assets. Our Chief Operating Decision Maker (“CODM”) is our Chief Executive Officer. The CODM allocates resources and evaluates the performance of Innoviva at the consolidated level using information about our revenues, operating results and other key financial data as needed. Our revenues are generated primarily from our collaborative arrangements and royalty payments from GSK, located in Great Britain. We also generate revenue from net sales of GIAPREZA® and XERAVA®. Our long-term assets are located within the United States.

Variable Interest Entities

We evaluate our ownership, contractual and other interest in entities to determine if they are a VIE. We evaluate whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluation, if we determine we are the primary beneficiary of a VIE, we consolidate the entity in our financial statements.

Business Combination

When we acquire an entity in a business combination, we recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establish the acquisition date as the fair value measurement point. We recognize and measure goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. Acquisition-related expenses and related restructuring costs are expensed as incurred.

Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use the income method. This method starts with a forecast of all of the expected future net cash flows for each asset. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. Determining the useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with a maturity of three months or less on the date of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.

Accounts Receivable, Net

Accounts receivable, net are recorded net of estimates for prompt-pay discounts, chargebacks, returns, rebates, and administrative fees. Allowances for prompt-pay discounts and chargebacks are based on contractual terms. We estimate the allowance for credit losses based on existing contractual payment terms, actual payment patterns of customers and individual customer circumstances.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value on a first in, first out basis. We periodically analyze inventory levels and write down inventory as cost of products sold when the following occurs: inventory has become obsolete, inventory has a cost basis in excess of its estimated net realizable value, or inventory quantities are in excess of expected product sales.

Goodwill and Intangible Assets

Goodwill is recognized as the excess of the purchase consideration of an acquired entity over the fair value assigned to assets acquired and liabilities assumed in a business combination. Goodwill and intangible assets with indefinite lives are subject to impairment testing at least annually or more frequently if indicators for potential impairment exist. Intangible assets with definite lives are amortized on a straight-line basis over the remaining useful life of the intangible asset. These assets are tested for impairment whenever events or changes in circumstances indicate that an asset’s carrying amount may not be recoverable. Significant judgments are involved in determining if an indicator of impairment has occurred.

Operating Leases

We account for our leases under ASC 842, Leases. Right-of-use assets represent our right to use an underlying asset over the lease term and include any lease payments made prior to the lease commencement date and are reduced by lease incentives. Lease liabilities represent the present value of the total lease payments over the lease term, calculated using an estimated incremental borrowing rate. Lease expense is recognized on a straight-line basis over the expected lease term.

Equity and Long-Term Investments

We invest from time to time in equity and debt securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we consolidate them in our unaudited condensed consolidated financial statements. If we determine that we do not have control over these companies under either voting or VIE models, we then determine if we have an ability to exercise significant influence via voting interests, board representation or other business relationships.

We may account for the investments where we exercise significant influence using either an equity method of accounting or at fair value by electing the fair value option. If the fair value option is applied to an investment that would otherwise be accounted for under the equity method, we apply it to all our financial interests in the same entity (equity and debt, including guarantees) that are eligible items. All gains and losses from fair value changes, unrealized and realized, are presented as changes in fair values of equity and long-term investments, net within the unaudited condensed consolidated statements of income.

If we conclude that we do not have an ability to exercise significant influence over an investee, we may elect to account for the security without a readily determinable fair value using the measurement alternative method under ASC 321, Investments - Equity Securities. This measurement alternative method allows us to measure the equity investment at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

We also invest in ISP Fund LP, which investments consist of money market funds and equity and debt securities in the healthcare, pharmaceutical and biotechnology industries. Pursuant to the Partnership Agreement entered in December 2020, we became a limited partner of this partnership, and our contributions are subject to a 36-month lock-up period which prevents us from having control and access to the contributions and related investments. These investments are classified as long-term investments on the unaudited condensed consolidated balance sheets.

Revenue Recognition

Revenue is recognized when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. Revenue is recognized through a five-step process: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price for the contract; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue as a performance obligation is satisfied.

Royalty Revenue from Collaboration Arrangement

We recognize the royalty revenue on net sales of products with respect to which we have contractual royalty rights in the period in which the royalties are earned. The net sales reports provided by our partner are based on its methodology and assumptions to estimate rebates and returns, which it monitors and adjusts regularly in light of contractual and legal obligations, historical trends, past experience and projected market conditions. Our partner may make significant adjustments to its sales based on actual results recorded, which could cause our royalty revenue to fluctuate. We conduct periodic royalty audits to evaluate the information provided by our partner. Royalties are recognized net of amortization of capitalized fees associated with any approval and launch milestone payments made to GSK.

Revenue from Product Sales

Revenue from product sales is recognized when our customers obtain control of the product and is recorded at the transaction price, net of estimates for variable consideration consisting of chargebacks, discounts, returns, rebates and administrative fees. Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. Actual amounts of consideration ultimately received may differ from our estimates. If actual results vary materially from our estimates, we will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. These items may include:

•

Chargebacks: Chargebacks are discounts we provide to distributors in the event that the sales prices to end users are below the distributors’ acquisition price. This may occur due to a direct contract with a health system, a group purchasing organization (“GPO”) agreement or a sale to a government facility. Chargebacks are estimated based on known chargeback rates and recorded as a reduction of revenue on delivery to our customers.

•

Discounts: We offer customers various forms of incentives and consideration, including prompt-pay and other discounts. We estimate discounts primarily based on contractual terms. These discounts are recorded as a reduction of revenue on delivery to our customers.

•

Returns: We offer customers a limited right of return, generally for damaged or expired product. We estimate returns based on an internal analysis, which includes actual experience. The estimates for returns are recorded as a reduction of revenue on delivery to our customers.

•

Rebates: We participate in Medicaid rebate programs, which provide assistance to certain low-income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, we pay a rebate to each participating state, generally within three months after the quarter in which product was sold. Additionally, we may offer customer incentives and consideration in the form of volume-based or other rebates. The estimates for rebates are recorded as a reduction of revenue on delivery to our customers.

•

Administrative Fees: We pay administrative fees to GPOs for services and access to data. Additionally, we pay an Industrial Funding Fee as part of the U.S. General Services Administration’s Federal Supply Schedules program. These fees are based on contracted terms and are paid after the quarter in which the product was purchased by the applicable GPO or government agency. Administrative fees are recorded as a reduction of revenue on delivery to customers.

We continue to assess our estimates of variable consideration as we accumulate additional historical data and will adjust these estimates accordingly.

Research and Development Costs

Research and development costs are expensed in the period that services are rendered or goods are received. Research and development costs consist of salaries and benefits, laboratory supplies, facilities and other overhead costs, research-related manufacturing costs, contract service and clinical-related service costs performed by third party research organizations, research institutions and other outside service providers. Non-refundable prepayments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as an expense as the related goods are delivered or the related services are performed. We also utilize significant judgment and estimates to record accruals for estimated ongoing research costs based on the progress of the studies and progress of research manufacturing activities.

Interest Expense on Deferred Royalty Obligation

Interest expense related to the deferred royalty obligation is recognized over the expected repayment term of the deferred royalty obligation using the effective interest method. The assumptions used in determining the expected repayment term of the deferred royalty obligation require us to make estimates that could impact the effective interest rate. Each reporting period, we estimate the expected repayment term of the deferred royalty obligation based on forecasted net sales of GIAPREZA®. Changes in interest expense resulting from changes in the effective interest rate, if any, are recorded on a prospective basis. Refer to Note 6, “Financial Instruments and Fair Value Measurements” for more information.

Accounting Pronouncement Adopted by the Company

In August 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20 for convertible instruments. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new standard also requires the if-converted method to be used to calculate diluted earnings per share (“EPS”) for convertible instruments.

Effective January 1, 2022, we adopted the new standard using the modified retrospective approach and assessed the effect of this adoption on the accounting for our outstanding convertible notes. The effect of the adoption on our 2025 Notes (as defined below) resulted in a decrease to the opening balance of accumulated deficit of $37.2 million, a reduction to additional paid-in capital of $65.4 million, an increase to the balance of the notes by an aggregate amount of $35.6 million, and an increase to deferred tax assets of $7.4 million. The dilutive EPS of our 2025 Notes will be computed under the if-converted method going forward. There was no financial impact from the implementation of the standard for our 2023 Notes (as defined below). Refer to Note 10, “Debt” for more information.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities (i.e., deferred revenue) acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. During the third quarter of 2022, we elected to early adopt ASU 2021-08 effective July 1, 2022. The adoption did not have a material impact on our unaudited, condensed consolidated financial statements.
