Organization and Significant Accounting Policies [Abstract] | |
Organization and Significant Accounting Policies | 1. Organization and Significant Accounting Policies Basis of Presentation In our consolidated financial statements we included the accounts of Ionis Pharmaceuticals, Inc. and the consolidated results of our subsidiary, Akcea Therapeutics, Inc. and its wholly owned subsidiaries (“we”, “us” or “our”). We formed Akcea in December 2014. In July 2017, Akcea completed an initial public offering, or IPO. Prior to Akcea’s IPO in July 2017, we owned of Akcea. In October 2020, we acquired the shares of Akcea’s common stock we did not own. We will refer to this transaction as the Akcea Acquisition throughout the remainder of this document. Akcea Acquisition We reflected changes in our ownership percentage in our financial statements as an adjustment to noncontrolling interest in the period the change occurred. Organization and Business Activity We incorporated in California on January 10, 1989. In conjunction with our IPO, we reorganized as a Delaware corporation in April 1991. We were organized principally to develop human therapeutic medicines using antisense technology. In December 2015, we changed our name from Isis Pharmaceuticals, Inc. to Ionis Pharmaceuticals, Inc. Basic and Diluted Net Income (Loss) per Share Basic net income (loss) per share We compute basic net income (loss) per share by dividing the total net income (loss) attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. The calculation of total net income (loss) attributable to our common stockholders for each year considered our net income (loss) for Ionis on a stand-alone basis plus our share of Akcea’s net income (loss) for the period. To calculate the portion of Akcea’s net income (loss) attributable to our ownership for each year, we multiplied Akcea’s income (loss) per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net income (loss) available to Ionis common stockholders for the calculation of net income (loss) per share is different than net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders in our consolidated statements of operations for each year. Our basic net income (loss) per share was calculated as follows (in thousands, except per share amounts): Year Ended December 31, 2020 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Loss Per Share Calculation Akcea’s net loss in the pre-acquisition period attributable to our ownership 77,095 $ (1.45 ) $ (111,775 ) Akcea’s net loss in the post-acquisition period attributable to our ownership (85,987 ) Akcea’s total net loss attributable to our ownership $ (197,762 ) Ionis’ stand-alone net loss (253,725 ) Net loss available to Ionis common stockholders $ (451,487 ) Weighted average shares outstanding 139,612 Basic net loss per share $ (3.23 ) Year Ended December 31, 2019 Weighted Average Shares Owned in Akcea Akcea s Net Income Per Share Basic Net Income Per Share Calculation Common shares 70,100 $ 0.49 $ 34,073 Akcea’s net income attributable to our ownership $ 34,073 Ionis’ stand-alone net income 262,490 Net income available to Ionis common stockholders $ 296,563 Weighted average shares outstanding 139,998 Basic net income per share $ 2.12 Year Ended December 31, 2018 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Income Per Share Calculation Common shares 59,812 $ (2.74 ) $ (163,938 ) Akcea’s net loss attributable to our ownership $ (163,938 ) Ionis’ stand-alone net income 440,806 Net income available to Ionis common stockholders $ 276,868 Weighted average shares outstanding 132,320 Basic net income per share $ 2.09 Diluted net income per share For the year ended December 31, 2020, we incurred a net loss; therefore, we did not include dilutive common equivalent shares in the computation of diluted net loss per share because the effect would have been anti-dilutive. Common stock from the following would have had an anti-dilutive effect on net loss per share: ● 0.125 percent convertible senior notes; ● 1 percent convertible senior notes; ● Dilutive stock options; ● Unvested restricted stock units, or RSUs; and ● Employee Stock Purchase Plan, or ESPP. For the years ended December 31, 2019 and 2018, we had net income available to Ionis common stockholders. As a result, we computed diluted net income per share using the weighted-average number of common shares and dilutive common equivalent shares outstanding during each period. (in thousands except per share amounts): Year Ended December 31, 2019 Income (Numerator) Shares (Denominator) Per-Share Amount Net income available to Ionis common stockholders $ 296,563 139,998 $ 2.12 Effect of dilutive securities: Shares issuable upon exercise of stock options — 2,090 Shares issuable upon restricted stock award issuance — 766 Shares issuable related to our ESPP — 18 $ 296,563 142,872 $ 2.08 Year Ended December 31, 2018 Income (Numerator) Shares (Denominator) Per-Share Amount Net income available to Ionis common stockholders $ 276,868 132,320 $ 2.09 Effect of dilutive securities: Shares issuable upon exercise of stock options — 1,216 Shares issuable upon restricted stock award issuance — 514 Shares issuable related to our ESPP — 6 $ 276,868 134,056 $ 2.07 For each year presented, the calculation excluded our convertible senior notes because the effect on diluted earnings per share was anti-dilutive. Revenue Recognition Our Revenue Sources We generally recognize revenue when we have satisfied all contractual obligations and are reasonably assured of collecting the resulting receivable. We are often entitled to bill our customers and receive payment from our customers in advance of recognizing the revenue. In the instances in which we have received payment from our customers in advance of recognizing revenue, we include the amounts in deferred revenue on our consolidated balance sheet. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We earn commercial revenue primarily in the form of royalty payments on net sales of SPINRAZA. We will also recognize as commercial revenue sales milestone payments and royalties we earn under our other partnerships. Commercial Revenue: Product sales, net We added product sales from TEGSEDI to our commercial revenue in the fourth quarter of 2018 and we added product sales from WAYLIVRA to our commercial revenue in the third quarter of 2019. In Europe, through 2020 we sold TEGSEDI and WAYLIVRA to hospitals and pharmacies using 3PLs as distributors. Beginning in 2021, we are commercializing TEGSEDI and WAYLIVRA in Europe through a distribution agreement with Swedish Orphan Biovitrum AB, or Sobi, an international biopharmaceutical company that focuses on rare diseases. Under the terms of this agreement, we retained the marketing authorization for both medicines in Europe. In Latin America beginning in 2020, we sold TEGSEDI and WAYLIVRA to our partner, PTC Therapeutics. Under our collaboration agreement with PTC, PTC is commercializing TEGSEDI and WAYLIVRA in Latin America and Caribbean countries. Research and development revenue under collaborative agreements We often enter into collaboration agreements to license and sell our technology on an exclusive or non-exclusive basis. Our collaboration agreements typically contain multiple elements, or performance obligations, including technology licenses or options to obtain technology licenses, research and development, or R&D, services, and manufacturing services. We provide details about our collaboration agreements in Note 6, Collaborative Arrangements and Licensing Agreements. Steps to Recognize Revenue We use a five-step process to determine the amount of revenue we should recognize and when we should recognize it. The five step process is as follows: 1. Identify the contract Accounting rules require us to first determine if we have a contract with our partner, including confirming that we have met each of the following criteria: ● We and our partner approved the contract and we are both committed to perform our obligations; ● We have identified our rights, our partner’s rights and the payment terms; ● We have concluded that the contract has commercial substance, meaning that the risk, timing, or amount of our future cash flows is expected to change as a result of the contract; and ● We believe collectability of the consideration is probable. 2 . Identify the performance obligations We next identify our performance obligations, which represent the distinct goods and services we are required to provide under the contract. We typically have only one performance obligation at the inception of a contract, which is to perform R&D services. Often we enter into a collaboration agreement in which we provide our partner with an option to license a medicine in the future. We may also provide our partner with an option to request that we provide additional goods or services in the future, such as active pharmaceutical ingredient, or API. We evaluate whether these options are material rights at the inception of the agreement. If we determine an option is a material right, we will consider the option a separate performance obligation. Historically, we have concluded that the options we grant to license a medicine in the future or to provide additional goods and services as requested by our partner are not material rights because these items are contingent upon future events that may not occur and are not priced at a significant discount. When a partner exercises its option to license a medicine or requests additional goods or services, then we identify a new performance obligation for that item In some cases, we deliver a license at the start of an agreement. If we determine that our partner has full use of the license and we do not have any additional material performance obligations related to the license after delivery, then we consider the license to be a separate performance obligation. 3. Determine the transaction price We then determine the transaction price by reviewing the amount of consideration we are eligible to earn under the collaboration agreement, including any variable consideration. Under our collaboration agreements, consideration typically includes fixed consideration in the form of an upfront payment and variable consideration in the form of potential milestone payments, license fees and royalties. At the start of an agreement, our transaction price usually consists of only the upfront payment. We do not typically include any payments we may receive in the future in our initial transaction price because the payments are not probable and are contingent on certain future events. We reassess the total transaction price at each reporting period to determine if we should include additional payments in the transaction price. Milestone payments are our most common type of variable consideration. We recognize milestone payments using the most likely amount method because we will either receive the milestone payment or we will not, which makes the potential milestone payment a binary event. The most likely amount method requires us to determine the likelihood of earning the milestone payment. We include a milestone payment in the transaction price once it is probable we will achieve the milestone event. Most often, we do not consider our milestone payments probable until we or our partner achieve the milestone event because the majority of our milestone payments are contingent upon events that are not within our control and/ or are usually based on scientific progress which is inherently uncertain. For example, in the fourth quarter of 2020 , we earned milestone payment from AstraZeneca when AstraZeneca initiated a Phase 2 b study for ION 449 , our medicine in development targeting PCSK 9 to lower LDL-cholesterol. We did not consider the milestone payment probable until AstraZeneca achieved the milestone event because advancing ION 449 was contingent on AstraZeneca initiating a Phase 2 b study and was not within our control. We recognized the milestone payment in full in the period the milestone event was achieved because we did not have any remaining performance obligations related to the milestone payment 4. Allocate the transaction price Next, we allocate the transaction price to each of our performance obligations. When we have to allocate the transaction price to more than performance obligation, we make estimates of the relative stand-alone selling price of each performance obligation because we do not typically sell our goods or services on a stand-alone basis. We then allocate the transaction price to each performance obligation based on the relative stand-alone selling price. We do not reallocate the transaction price after the start of an agreement to reflect subsequent changes in stand-alone selling prices. We may engage a party, independent valuation specialist to assist us with determining a stand-alone selling price for collaborations in which we deliver a license at the start of an agreement. We estimate the stand-alone selling price of these licenses using valuation methodologies, such as the relief from royalty method. Under this method, we estimate the amount of income, net of taxes, for the license. We then discount the projected income to present value. The significant inputs we use to determine the projected income of a license could include ● Estimated future product sales; ● Estimated royalties we may receive from future product sales; ● Estimated contractual milestone payments we may receive; ● Expenses we expect to incur; ● Estimated income taxes; and ● A discount rate. We typically estimate the selling price of R&D services by using our internal estimates of the cost to perform the specific services. The significant inputs we use to determine the selling price of our R&D services include: ● The number of internal hours we estimate we will spend performing these services; ● The estimated cost of work we will perform; ● The estimated cost of work that we will contract with third parties to perform; and ● The estimated cost of API we will use. For purposes of determining the stand-alone selling price of the R&D services we perform and the API we will deliver, accounting guidance requires us to include a markup for a reasonable profit margin. 5. Recognize revenue We recognize revenue in of ways, over time or at a point in time. We recognize revenue over time when we are executing on our performance obligation over time and our partner receives benefit over time. For example, we recognize revenue over time when we provide R&D services. We recognize revenue at a point in time when our partner receives full use of an item at a specific point in time. For example, we recognize revenue at a point in time when we deliver a license or API to a partner. For R&D services that we recognize over time, we measure our progress using an input method. The input methods we use are based on the effort we expend or costs we incur toward the satisfaction of our performance obligation. We estimate the amount of effort we expend, including the time we estimate it will take us to complete the activities, or costs we incur in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that we multiply by the transaction price to determine the amount of revenue we recognize each period. This approach requires us to make numerous estimates and use significant judgement. If our estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that we recognize in the current and future periods. Collaborative Arrangements and Licensing Agreements The following are examples of when we typically recognize revenue based on the types of payments we receive. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We recognize royalty revenue, including royalties from SPINRAZA sales, in the period in which the counterparty sells the related product and recognizes the related revenue, which in certain cases may require us to estimate our royalty revenue Commercial Revenue: Product sales, net We recognize product sales in the period when our customer obtains control of our products, which occurs at a point in time upon transfer of title to the customer. We classify payments to customers or other parties in the distribution channel for services that are distinct and priced at fair value as selling, general and administrative, or SG&A, expenses in our consolidated statements of operations. Otherwise, payments to customers or other parties in the distribution channel that do not meet those criteria are classified as a reduction of revenue, as discussed further below. We exclude from revenues taxes collected from customers relating to product sales and remitted to governmental authorities Reserves for Product sales We record product sales at our net sales price, or transaction price. We include in our transaction price estimated reserves for discounts, returns, chargebacks, rebates and other allowances that we offer within contracts between us and our customers, wholesalers, health care providers and other indirect customers. We estimate our reserves using the amounts we have earned or what we can claim on the associated sales. We classify our reserves as a reduction of accounts receivable when we are not required to make a payment or as a current liability when we are required to make a payment. In certain cases, our estimates include a range of possible outcomes that are probability weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, our reserves reflect our best estimates under the terms of our respective contracts. When calculating our reserves and related product sales, we only recognize amounts to the extent that we consider it probable that we would not have to reverse in a future period a significant amount of the cumulative sales we previously recognized. The actual amounts we receive may ultimately differ from our reserve estimates. If actual amounts in the future vary from our estimates, we will adjust these estimates, which would affect our net product sales in the respective period The following are the components of variable consideration related to product sales: Chargebacks: In the U.S., we estimate obligations resulting from contractual commitments with the government and other entities to sell products to qualified healthcare providers at prices lower than the list prices charged to our U.S. customer. Our U.S. customer charges us for the difference between what it pays for the product and the selling price to the qualified healthcare providers. We also estimate the amount of chargebacks related to our estimated product remaining in the distribution channel at the end of the reporting period that we expect our customer to sell to healthcare providers in future periods. We record these reserves as a reduction to contracts receivable on our consolidated balance sheet Government rebates : We are subject to discount obligations under government programs, including Medicaid and Medicare programs in the U.S. and we record reserves for government rebates based on statutory discount rates and estimated utilization. We estimate Medicaid and Medicare rebates based on a range of possible outcomes that are probability weighted for the estimated payer mix. We record these reserves as an accrued liability on our consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. For Medicare, we also estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program. On a quarterly basis, we update our estimates and record any adjustments in the period that we identify the adjustments Managed care rebates: We are subject to rebates in connection with agreements with certain contracted commercial payers. We record these rebates as a liability on our consolidated balance sheet in the same period we recognize the related revenue. We estimate our managed care rebates based on our estimated payer mix and the applicable contractual rebate rate Trade discounts: We provide customary invoice discounts on product sales to our U.S. customer for prompt payment. We record this discount as a reduction of product sales in the period in which we recognize the related product revenue Distribution services We receive and pay for various distribution services from our U.S. and European customers (prior to our agreement with Sobi) and wholesalers in the U.S. We classify the costs for services we receive that are either not distinct from the sale of the product or for which we cannot reasonably estimate the fair value as a reduction of product sales. To the extent that the services we receive are distinct from the sale of the product, we classify the costs for such services as SG&A expenses. Product returns: Our U.S. customer has return rights and the wholesalers have limited return rights primarily related to the product’s expiration date. We estimate the amount of product sales that our customer may return. We record our return estimate as an accrued refund liability on our consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. Based on our distribution model for product sales, contractual inventory limits with our customer and wholesalers and the price of the product, we have had minimal returns to date and we believe we will continue to have minimal returns in the U.S. Our European customers generally only take title to the product after they receive an order and therefore they do not maintain excess inventory levels of our products. Accordingly, we have limited return risk in Europe and we do not estimate returns in Europe Research and development revenue under collaboration agreements: Upfront payments When we enter into a collaboration agreement with an upfront payment, we typically record the entire upfront payment as deferred revenue if our only performance obligation is for R&D services we will provide in the future. We amortize the upfront payment into revenue as we perform the R&D services. For example, under our collaboration agreement with Roche to develop IONIS-FB-L Rx for the treatment of complement-mediated diseases, we received a $ million upfront payment in the fourth quarter of 2018. We allocated the upfront payment to our single performance obligation, R&D services. We are amortizing the $ million upfront payment using an input method over the estimated period of time we are providing R&D services Milestone payments We are required to include additional consideration in the transaction price when it is probable. We typically include milestone payments for R&D services in the transaction price when they are achieved. We include these milestone payments when they are achieved because typically there is considerable uncertainty in the research and development processes that trigger these payments. Similarly, we include approval milestone payments in the transaction price once the medicine is approved by the applicable regulatory agency. We will recognize sales-based milestone payments in the period in which we achieve the milestone under the sales-based royalty exception allowed under accounting rules. We recognize milestone payments that relate to an ongoing performance obligation over our period of performance. For example, in the fourth quarter of 2020 , we achieved a million milestone payment from Biogen when we advanced a We added this payment to the transaction price and allocated it to our R&D services performance obligation. We are recognizing revenue related to this milestone payment over our estimated period of performance Conversely, we recognize in full those milestone payments that we earn based on our partners’ activities when our partner achieves the milestone event and we do not have a performance obligation. For example, in the third quarter of 2020, we recognized $18 million in milestone payments when Biogen initiated a Phase 1/2 trial for ION464, our medicine in development targeting alpha-synuclein to treat patients with multiple system atrophy We concluded that the milestone payments were not related to our R&D services performance obligation. Therefore, we recognized the milestone payments in full in the third quarter of 2020. License fees We generally recognize as revenue the total amount we determine to be the relative stand-alone selling price of a license when we deliver the license to our partner. This is because our partner has full use of the license and we do not have any additional performance obligations related to the license after delivery. For example, in the fourth quarter of 2020 , we earned a million license fee from AstraZeneca when AstraZeneca licensed ION 455 , an investigational medicine in development to treat nonalcoholic steatohepatitis, or NASH. Sublicense fees We recognize sublicense fee revenue in the period in which a party, who has already licensed our technology, further licenses the technology to another party because we do not have any performance obligations related to the sublicense. Amendments to Agreements From time to time we amend our collaboration agreements. When this occurs, we are required to assess the following items to determine the accounting for the amendment: 1) If the additional goods and/or services are distinct from the other performance obligations in the original agreement; and 2) If the goods and/or services are at a stand-alone selling price. If we conclude the goods and/or services in the amendment are distinct from the performance obligations in the original agreement and at a stand-alone selling price, we account for the amendment as a separate agreement. If we conclude the goods and/or services are not distinct and are sold at a stand-alone selling price, we then assess whether the remaining goods or services are distinct from those already provided. If the goods and/or services are distinct from what we have already provided, then we allocate the remaining transaction price from the original agreement and the additional transaction price from the amendment to the remaining goods and/or services. If the goods and/or services are not distinct from what we have already provided, we update the transaction price for our single performance obligation and recognize any change in our estimated revenue as a cumulative adjustment. For example, in May 2015, we entered into an exclusive license agreement with Bayer to develop and commercialize IONIS-FXI Rx for the prevention of thrombosis. As part of the agreement, Bayer paid us a $ million upfront payment. At the onset of the agreement, we were responsible for completing a Phase 2 study of IONIS-FXI Rx in people with end-stage renal disease on hemodialysis and for providing an initial supply of API. In February 2017, we amended our agreement with Bayer to advance IONIS-FXI Rx and to initiate development of IONIS-FXI-L Rx , which Bayer licensed. As part of the 2017 amendment, Bayer paid us $ million. We are also eligible to receive milestone payments and tiered royalties on gross margins of IONIS-FXI Rx and IONIS-FXI-L Rx . Under the 2017 amendment, we concluded we had a new agreement with performance obligations. These performance obligations were to deliver the license of IONIS-FXI-L Rx , to provide R&D services and to deliver API. We allocated the $ million transaction price to these performance obligations. Refer to Note 6, Collaborative Arrangements and Licensing Agreements , for further discussion of the Bayer collaboration. Multiple agreements From time to time, we may enter into separate agreements at or near the same time with the same partner. We evaluate such agreements to determine whether we should account for them individually as distinct arrangements or whether the separate agreements should be combined and accounted for together. We evaluate the following to determine the accounting for the agreements: ● Whether the agreements were negotiated together with a single objective; ● Whether the amount of consideration in one contract depends on the price or performance of the other agreement; or ● Whether the goods and/or services promised under the agreements are a single performance obligation. Our evaluation involves significant judgment to determine whether a group of agreements might be so closely related that accounting guidance requires us to account for them as a combined arrangement. For example, in the second quarter of 2018, we entered into two separate agreements with Biogen at the same time: a new strategic neurology collaboration agreement and a stock purchase agreement, or SPA. We evaluated the Biogen agreements to determine whether we should treat the agreements separately or combine them. We considered that the agreements were negotiated concurrently and in contemplation of one another. Based on these facts and circumstances, we concluded that we should evaluate the provisions of the agreements on a combined basis . Contracts Receivable Our contracts receivable balance represents the amounts we have billed our partners or customers and that are due to us unconditionally for goods we have delivered or services we have performed. When we bill our partners or customers with payment terms based on the passage of time, we consider the contracts receivable to be unconditional. We typically receive payment within one quarter of billing our partner or customer Unbilled SPINRAZA Royalties Our unbilled SPINRAZA royalties represent our right to receive consideration from Biogen in advance of when we are eligible to bill Biogen for SPINRAZA royalties. We include these unbilled amounts in other current assets on our consolidated balance sheet. Deferred Revenue We are often entitled to bill our customers and receive payment from our customers in advance of our obligation to provide services or transfer goods to our partners. In these instances, we include the amounts in deferred revenue on our consolidated balance sheet. Cost of Products Sold Our cost of products sold includes manufacturing costs, transportation and freight costs and indirect overhead costs associated with the manufacturing and distribution of our products. We also may include certain period costs related to manufacturing services and inventory adjustments in cost of products sold. Prior to obtaining regulatory approval of TEGSEDI in July 2018 and WAYLIVRA in May 2019, we expensed as research and development expenses a significant portion of the costs we incurred to produce the initial commercial launch supply for each medicine. Research, Development and Patent Expenses Our research and development expenses include wages, benefits, facilities, supplies, external services, clinical trial and manufacturing costs and other expenses that are directly related to our research and development operations. We expense research and development costs as we incur them. When we make payments for research and development services prior to the services being rendered, we record those amounts as prepaid assets on our consolidated balance sheet and we expense them as the services are provided. For the years ended December 31, 2020, 2019 and 2018, research and development expenses were $531.0 million, $461.5 million and $411.9 million, respectively. A portion of the costs included in research and development expenses are costs associated with our partner agreements. For the years ended December 31, 2020, 2019 and 2018, research and development costs of approximately $49.8 million, $83.2 million and $58.7 million, respectively, were related to our partner agreements. We capitalize costs consisting principally of outside legal costs and filing fees related to obtaining patents. We amortize patent costs over the useful life of the patent, beginning with the date the U.S. Patent and Trademark Office, or foreign equivalent, issues the patent. The weighted average remaining amortizable life of our issued patents was 10.3 years at December 31, 2020. The cost of our patents capitalized on our consolidated balance sheet at December 31, 2020 and 2019 was $37.0 million and $34.0 million, respectively. Accumulated amortization related to patents was $9.1 million and $8.3 mill |

Investments | 2. Investments The following table summarizes the contract maturity of the available-for-sale securities we held as of December 31, 2020: One year or less 73 % After one year but within two years 18 % After two years but within three and a half years 9 % Total 100 % As illustrated above, at December 31, 2020, 91 percent of our available-for-sale securities had a maturity of less than two years. All of our available-for-sale securities are available to us for use in our current operations. As a result, we categorize all of these securities as current assets even though the stated maturity of some individual securities may be one year or more beyond the balance sheet date. At December 31, 2020, we had an ownership interest of less than 20 percent in seven private companies and two public companies with which we conduct business. The privately-held companies are The following is a summary of our investments (in thousands): Gross Unrealized Estimated December 31, 2020 Cost Gains Losses Fair Value Available-for-sale securities: Corporate debt securities (2) $ 514,182 $ 2,194 $ (41 ) $ 516,335 Debt securities issued by U.S. government agencies 94,234 354 (2 ) 94,586 Debt securities issued by the U.S. Treasury (2) 307,576 233 (9 ) 307,800 Debt securities issued by states of the U.S. and political subdivisions of the states 104,271 196 (12 ) 104,455 Other municipal debt securities 5,191 — (7 ) 5,184 Total securities with a maturity of one year or less 1,025,454 2,977 (71 ) 1,028,360 Corporate debt securities 325,079 4,941 (40 ) 329,980 Debt securities issued by U.S. government agencies 80,099 185 (9 ) 80,275 Debt securities issued by the U.S. Treasury 50,318 383 (4 ) 50,697 Debt securities issued by states of the U.S. and political subdivisions of the states 31,779 91 (16 ) 31,854 Other municipal debt securities 1,041 — — 1,041 Total securities with a maturity of more than one year 488,316 5,600 (69 ) 493,847 Total available-for-sale securities $ 1,513,770 $ 8,577 $ (140 ) $ 1,522,207 Equity securities: Total equity securities included in other current assets (3) $ 4,712 $ — $ (2,681 ) $ 2,031 Total equity securities included in deposits and other assets (4) 15,062 15,938 — 31,000 Total equity securities $ 19,774 $ 15,938 $ (2,681 ) $ 33,031 Total available-for-sale and equity securities $ 1,533,544 $ 24,515 $ (2,821 ) $ 1,555,238 Gross Unrealized Estimated December 31, 2019 Cost Gains Losses Fair Value Available-for-sale securities: Corporate debt securities (2) $ 669,665 $ 1,451 $ (43 ) $ 671,073 Debt securities issued by U.S. government agencies 188,216 303 (43 ) 188,476 Debt securities issued by the U.S. Treasury (2) 327,670 232 (27 ) 327,875 Debt securities issued by states of the U.S. and political subdivisions of the states 21,065 26 (5 ) 21,086 Total securities with a maturity of one year or less 1,206,616 2,012 (118 ) 1,208,510 Corporate debt securities 428,627 2,911 (43 ) 431,495 Debt securities issued by U.S. government agencies 140,988 57 (117 ) 140,928 Debt securities issued by the U.S. Treasury 35,822 9 (12 ) 35,819 Debt securities issued by states of the U.S. and political subdivisions of the states 19,309 18 (6 ) 19,321 Total securities with a maturity of more than one year 624,746 2,995 (178 ) 627,563 Total available-for-sale securities $ 1,831,362 $ 5,007 $ (296 ) $ 1,836,073 Equity securities: Total equity securities included in other current assets (3) $ 4,712 $ — $ (870 ) $ 3,842 Total equity securities included in deposits and other assets (4) 10,000 — — 10,000 Total equity securities $ 14,712 $ — $ (870 ) $ 13,842 Total available-for-sale and equity securities $ 1,846,074 $ 5,007 $ (1,166 ) $ 1,849,915 ________________ (1) We hold our available-for-sale securities at amortized cost. (2) Includes investments classified as cash equivalents on our consolidated balance sheet. (3) Our equity securities included in other current assets consisted of our investments in publicly traded companies. We recognize publicly traded equity securities at fair value. (4) Our equity securities included in deposits and other assets consisted of our investments in privately held companies. We recognize our private company equity securities at on our consolidated balance sheet. The following is a summary of our investments we considered to be temporarily impaired at (in thousands). All of these investments have less than 12 months of temporary impairment. We believe that the decline in value of these securities is temporary and is primarily related to the change in market interest rates since purchase. We believe it is more likely than not that we will be able to hold our debt securities to maturity. Therefore, we anticipate full recovery of our debt securities’ amortized cost basis at maturity.

Long-Term Obligations and Commitments | 3. Long-Term Obligations and Commitments The carrying value of our long-term obligations was as follows (in thousands): December 31, 2020 2019 0.125 percent convertible senior notes $ 455,719 $ 434,711 1 percent convertible senior notes (1) 293,161 275,333 Long-term mortgage debt 59,984 59,913 Leases and other obligations 30,710 17,569 Total $ 839,574 $ 787,526 Less: current portion (1) (300,462 ) (2,026 ) Total Long-Term Obligations $ 539,112 $ 785,500 ________________ (1) We classified the carrying value of our 1% Notes as a current liability on our consolidated balance sheet at December 31, 2020 because it matures in November 2021. Convertible Notes and Call Spread 0.125 Percent Convertible Senior Notes In December 2019, we entered into privately negotiated exchange and/or subscription agreements with certain new investors and certain holders of our existing 1% 1% n conjunction with the December 2019 exchange, we entered into a call spread transaction, which was comprised of purchasing note hedges and selling warrants, to minimize the impact of potential economic dilution upon conversion of our by increasing the effective conversion price even further. Interest is payable semi-annually on June 15 and December 15 of each year for the 0.125% 0.125% 0.125% 0.125% 0.125% At December 31, 2020, we had the following 0.125% 0.125% Notes Outstanding principal balance $ 548.8 Maturity date December 15, 2024 Interest rate 0.125 % Conversion price per share $ 83.28 Total shares of common stock subject to conversion 6.6 The following table summarizes information about the equity and liability components of our outstanding 0.125% Notes (in millions). We measured the fair values of the convertible notes outstanding based on quoted market prices, which is a Level 2 measurement at December 31, and : December 31, 2020 2019 Fair value of outstanding notes $ 564.9 $ 558.7 Principal amount of convertible notes outstanding $ 548.8 $ 548.8 Unamortized portion of debt discount $ 86.0 $ 105.2 Long-term debt $ 455.7 $ 434.7 Carrying value of equity component $ 105.8 $ 105.8 Call Spread Additionally, i 0.125% Notes The call spread cost us $ million, of which $ million was for the note hedge purchase, offset by $ million we received for selling the warrants. We increased our effective conversion price to $ with the same number of underlying shares as our 0.125% Notes . Similar to our 0.125% Notes , our note hedges are subject to adjustment. Additionally, our note hedges are exercisable upon conversion of the 0.125% Notes . The note hedges will expire upon maturity of 0.125% Notes , or December 2024. The note hedges and warrants are separate transactions and are not part of the terms of our 0.125% Notes . The holders of the 0.125% Notes do not have any rights with respect to the note hedges and warrants. We recorded the aggregate amount paid for the note hedges and the aggregate amount received for the warrants in additional paid-in capital in our consolidated balance sheet. We excluded shares under the note hedges from our calculation of diluted earnings per share as they were antidilutive. We will include the shares issuable under the warrants in our calculation of diluted earnings per share when the average market price per share of our common stock for the reporting period exceeds the strike price of the warrants. 1 Percent Convertible Senior Notes In November 2014, we completed a $500 million offering of convertible senior notes, which mature in 2021 and bear interest at 1 percent. We used a substantial portion of the net proceeds from the issuance of the 1% Notes to repurchase $140 million in principal of our 2¾ percent 2¾% 2¾% 0.125% At December 31, 2020, we had the following 1% Notes outstanding (amounts in millions except price per share data): 1% Notes Outstanding principal balance $ 309.9 Maturity date November 30, 2021 Interest rate 1 percent Conversion price per share $ 66.81 Total shares of common stock subject to conversion 4.6 Interest is payable semi-annually in arrears on May 15 and November 15 of each year for the 1% Notes. The 1% Notes are convertible at the option of the note holders prior to July 1, 2021 only under certain conditions. On or after July 1, 2021, the 1% Notes are initially convertible into approximately 4.6 million shares of common stock at a conversion price of approximately $66.81 per share. We will settle conversions of the notes, at our election, in cash, shares of our common stock or a combination of both. We may not redeem the 1% Notes prior to maturity, and no sinking fund is provided for them. If we undergo a fundamental change, holders may require us to purchase for cash all or any portion of their 1% Notes at a purchase price equal to 100 percent of the principal amount of the notes to be purchased, plus accrued and unpaid interest to, but excluding, the fundamental change purchase date. The following table summarizes information about the equity and liability components of our outstanding Notes (in millions). We measured the fair values of the convertible notes outstanding based on quoted market prices, which is a Level 2 measurement at December 31, and : December 31, 2020 2019 Fair value of outstanding notes $ 338.5 $ 354.8 Principal amount of convertible notes outstanding $ 309.9 $ 309.9 Unamortized portion of debt discount $ 15.8 $ 32.8 Current/long-term debt $ 293.2 $ 275.3 Carrying value of equity component $ 33.5 $ 33.5 We account for our convertible notes using an accounting standard that requires us to assign a value to our convertible debt equal to the estimated fair value of similar debt instruments without the conversion feature and to record the remaining portion in equity. As a result, we recorded our convertible notes at a discount, which we are amortizing as additional non-cash interest expense over the expected life of the respective debt. We determined our nonconvertible debt borrowing rate using a combination of the present value of the debt’s cash flows and a Black-Scholes valuation model. The following table summarizes the nonconvertible borrowing rate, effective interest rate and amortization period of our debt discount for our convertible notes: 1% Notes 0.125% Nonconvertible debt borrowing rate 7.4 percent 4.4 percent Effective interest rate (1) 7.5 percent 4.9 percent Amortization period of debt discount 7 years 5 years ________________ (1) For our 1% Notes, our effective interest rate represents our effective interest rate after our December 2019 debt exchange. Our total interest expense for our outstanding senior convertible notes for the years ended December 31, 2020, 2019 and 2018 included $38.7 million, $39.3 million and $35.2 million, respectively, of non-cash interest expense related to the amortization of the debt discount and debt issuance costs for our convertible notes. Financing Arrangements Line of Credit Arrangement In June 2015, we entered into a five-year revolving line of credit agreement with Morgan Stanley Private Bank, National Association, or Morgan Stanley, which we amended in February 2016. Under the amended credit agreement, Morgan Stanley provided a maximum of $30 million of revolving credit for general working capital purposes. During the third quarter of 2019, we paid off our total outstanding borrowings of $12.5 million under the agreement and subsequently terminated the agreement. Research and Development and Manufacturing Facilities In July 2017, we purchased the building that houses our primary R&D facility for $79.4 million and our manufacturing facility for $14.0 million. We financed the purchase of these two facilities with mortgage debt of $60.4 million in total. Our primary R&D facility mortgage has an interest rate of 3.88 percent. Our manufacturing facility mortgage has an interest rate of 4.20 percent. During the first five years of both mortgages, we are only required to make interest payments. Both mortgages mature in August 2027. Maturity Schedules Annual debt and other obligation maturities, including fixed and determinable interest, at December 31, 2020 are as follows (in thousands): 2021 $ 329,189 2022 3,495 2023 4,180 2024 553,006 2025 3,494 Thereafter 60,933 Subtotal $ 954,297 Less: current portion (300,462 ) Less: fixed and determinable interest (21,758 ) Less: unamortized portion of debt discount (101,820 ) Less: debt issuance costs (8,455 ) Plus: lease liabilities 17,310 Total long-term debt $ 539,112 Operating Leases Carlsbad Leases We lease a facility adjacent to our manufacturing facility that has laboratory and office space that we use to support our manufacturing facility. We lease this space under a non-cancelable operating lease. In May 2020, we exercised our option to extend our lease, extending our lease term from June 2021 to August 2026. We have one remaining option to extend the lease for an additional five-year period. We also lease additional office spaces in Carlsbad. We lease these spaces under non-cancelable operating leases with initial terms ending in 2023 with options to extend each of the leases for one five-year period. Boston Lease We entered into an operating lease agreement for office space located in Boston, Massachusetts in the second quarter of 2018. The lease commencement date was in August 2018 and we took occupancy in September 2018. We are leasing this space under a non-cancelable operating lease with an initial term ending after 123 months and an option to extend the lease for an additional five-year term. Under the lease agreement, we received a three-month free rent period, which commenced on August 15, 2018, and a tenant improvement allowance up to $3.8 million. We provided the lessor with a letter of credit to secure its obligations under the lease in the initial amount of $2.4 million, to be reduced to $1.8 million on the third anniversary of the rent commencement date and to $1.2 million on the fifth anniversary of the rent commencement date if we meet certain conditions set forth in the lease at each such time. When we determined our lease term for our operating lease right-of-use assets and lease liabilities for these leases, we did not include the extension options for these leases in the original lease term. Amounts related to our operating leases were as follows (dollar amounts in millions): At December 31, 2020 Right-of-use operating lease assets (1) $ 13.1 Operating lease liabilities (2) $ 17.3 Weighted average remaining lease term 7.2 years Weighted average discount rate 7.0 % ________________ (1) Included in deposits and other assets (2) Current portion of $2.0 million was included in current portion of long-term obligations long-term obligations During the years ended December 31, 2020, 2019, and 2018 we paid $3.8 million, $3.9 million and $1.7 million of lease payments, which were included in operating activities in our consolidated statement of cash flows. As of December 31, 2020, the future payments for our operating lease liabilities are as follows (in thousands): Operating Leases Year ending December 31, $ 2021 3,193 2022 2,968 2023 2,707 2024 2,583 2025 2,442 Thereafter 7,038 Total minimum lease payments 20,931 Less: Imputed interest (3,621 ) Total operating lease liabilities $ 17,310 Rent expense was $3.7 million, $3.6 million and $2.6 million for the years ended December 31, 2020, 2019 and 2018, respectively. |

Stockholders' Equity [Abstract] | |
Stockholders' Equity | 4. Stockholders Equity Preferred Stock We are authorized to issue up to 15 million shares of “blank check” Preferred Stock. As of December 31, 2020, there were no shares of Preferred Stock outstanding. We have designated Series C Junior Participating Preferred Stock but have no issued or outstanding shares as of December 31, 2020. Common Stock At December 31, 2020 and 2019, we had 300 million shares of common stock authorized, of which 140.4 million and 140.3 million were issued and outstanding, respectively. As of December 31, 2020, total common shares reserved for future issuance were 26.1 million. During the years ended December 31, 2020, 2019 and 2018, we issued 1.7 million, 3.1 million and 1.5 million shares of common stock, respectively, for stock option exercises, vesting of restricted stock units, and ESPP purchases. We received net proceeds from these transactions of $52.0 million, $119.7 million and $27.9 million in 2020, 2019 and 2018, respectively. Share Repurchase Program In September 2019, our board of directors approved a share repurchase program of up to $125 million of our common stock. In 2019, we repurchased 535,000 shares for $34.4 million. In the first quarter of 2020, we repurchased an additional 1.5 million shares for $90.5 million. Stock Plans 1989 Stock Option Plan In June 1989, our Board of Directors adopted, and the stockholders subsequently approved, a stock option plan that, as amended, provides for the issuance of non-qualified and incentive stock options for the purchase of up to 20.0 million shares of common stock to our employees, directors, and consultants. The plan expires in January 2024. The 1989 Plan does not allow us to grant stock bonuses or restricted stock awards and prohibits us from repricing any options outstanding under the plan unless our stockholders approve the repricing. Options vest over a four-year period, with 25percent exercisable at the end of one year from the date of the grant and the balance vesting ratably, on a monthly basis, thereafter and have a term of seven years. At December 31, 2020, a total of 30 thousand options were outstanding, of which options to purchase 30 thousand shares were exercisable, and 50 thousand shares were available for future grant under the 1989 Plan. 2011 Equity Incentive Plan In March 2011, our Board of Directors adopted, and the stockholders subsequently approved, a stock option plan that provides for the issuance of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and performance cash awards to our employees, directors, and consultants. In June 2015, May 2017 and June 2019, after receiving approval from our stockholders, we amended our 2011 Equity Incentive Plan to increase the total number of shares reserved for issuance. We increased the shares available under our 2011 Equity Incentive Plan from 5.5 million to 11.0 million in June 2015, from 11.0 million to 16.0 million in May 2017 and from 16.0 million to 23.0 million in June 2019. The plan expires in June 2031. The 2011 Plan does not allow us to reduce the exercise price of any outstanding stock options or stock appreciation rights or cancel any outstanding stock options or stock appreciation rights that have an exercise price or strike price greater than the current fair market value of the common stock in exchange for cash or other stock awards unless our stockholders approve such action. Currently we anticipate awarding only options and restricted stock unit awards to our employees, directors and consultants. We have granted restricted stock unit awards to our employees under the 2011 Plan which vest annually over a four-year period. At December 31, 2020, a total of 11.4 million options were outstanding, of which 6.7 million were exercisable, 2.2 million restricted stock unit awards were outstanding, and 4.3 million shares were available for future grant under the 2011 Plan. Under the 2011 Plan, we may issue a stock award with additional acceleration of vesting and exercisability upon or after a change in control. In the absence of such provisions, no such acceleration will occur. The stock options and restricted stock unit awards we issued to Dr. Stanley T. Crooke in his former role as chief executive officer and certain stock options and restricted stock unit awards we issued to B. Lynne Parshall in her former role as chief operating officer will accelerate upon a change of control, as defined in the 2011 Plan. In addition, we implemented a change of control and severance benefit plan that provides for change of control and severance benefits to our executive officers, including our chief executive officer and chief financial officer. If we terminate one of our executive officers or if an executive officer resigns for good reason during the period that begins three months before and ends twelve months following a change in control of the company, the impacted executive officers’ stock options and RSUs vesting will accelerate for options and RSUs outstanding as of the termination date. 2020 Equity Incentive Plan In connection with the Akcea Acquisition in October 2020, we assumed the unallocated portion of the available share reserve under the Akcea 2015 Equity Incentive Plan. In December 2020, we amended and restated the Akcea 2015 equity plan, including renaming the plan as the Ionis Pharmaceuticals, Inc. 2020 Equity Incentive Plan, or 2020 Plan. The 2020 Plan provided for the issuance of up to million shares of our Common Stock to our employees, directors and consultants who were employees of Akcea prior to the Akcea Acquisition. The plan expires in December 2025. The 2020 Plan does not allow us to reduce the exercise price of any outstanding stock options or stock appreciation rights or cancel any outstanding stock options or stock appreciation rights that have an exercise price or strike price greater than the current fair market value of the common stock in exchange for cash or other stock awards unless our stockholders approve such action. Currently we anticipate awarding only options and restricted stock unit awards to our eligible employees, directors and consultants. We have granted stock options to our employees under the 2020 Plan which vest annually over a four-year period. At December 31, 2020, a total of 0.01 million options were outstanding, of which none were exercisable, and 2.6 million shares were available for future grant under the 2020 Plan. Under the 2020 Plan, we may issue a stock award with additional acceleration of vesting and exercisability upon or after a change in control. In the absence of such provisions, no such acceleration will occur. Corporate Transactions and Change in Control under 2011 and 2020 Plans In the event of certain significant corporate transactions, our Board of Directors has the discretion to take one or more of the following actions with respect to outstanding stock awards under the 2011 and 2020 Plans: ● arrange for assumption, continuation, or substitution of a stock award by a surviving or acquiring entity (or its parent company); ● arrange for the assignment of any reacquisition or repurchase rights applicable to any shares of our common stock issued pursuant to a stock award to the surviving or acquiring corporation (or its parent company); ● accelerate the vesting and exercisability of a stock award followed by the termination of the stock award; ● arrange for the lapse of any reacquisition or repurchase rights applicable to any shares of our common stock issued pursuant to a stock award; ● cancel or arrange for the cancellation of a stock award, to the extent not vested or not exercised prior to the effective date of the corporate transaction, in exchange for cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and ● arrange for the surrender of a stock award in exchange for a payment equal to the excess of (a) the value of the property the holder of the stock award would have received upon the exercise of the stock award, over (b) any exercise price payable by such holder in connection with such exercise. 2002 Non-Employee Directors’ Stock Option Plan In September 2001, our Board of Directors adopted, and the stockholders subsequently approved, an amendment and restatement of the 1992 Non-Employee Directors’ Stock Option Plan, which provides for the issuance of non-qualified stock options and restricted stock units to our non-employee directors. The name of the resulting plan is the 2002 Non-Employee Directors’ Stock Option Plan, or the 2002 Plan. In June 2015, after receiving approval from our stockholders, we amended our 2002 Plan to increase the total number of shares reserved for issuance from 1.2 million to 2.0 million. In June 2020, after receiving approval from our stockholders, we further amended our 2002 Plan. The amendments included: ● An increase to the total number of shares reserved for issuance under the plan from million to million shares; ● A reduction to the amount of the automatic awards under the plan; ● A revision to the vesting schedule of new awards granted; and ● An extension of the term of the plan. Options under this plan expire 10 years from the date of grant. At December 31, 2020, a total of 1.0 million options were outstanding, of which 0.6 million were exercisable, 0.1 million restricted stock unit awards were outstanding, and 0.8 million shares were available for future grant under the 2002 Plan. Employee Stock Purchase Plan In June 2009, our Board of Directors adopted, and the stockholders subsequently approved, the amendment and restatement of the ESPP and we reserved an additional 150,000 shares of common stock for issuance thereunder. In each of the subsequent years until 2019, we reserved an additional 150,000 shares of common stock for the ESPP resulting in a total of 3.2 million shares authorized under the plan as of December 31, 2020. The ESPP permits full-time employees to purchase common stock through payroll deductions (which cannot exceed 10percent of each employee’s compensation) at the lower of 85percent of fair market value at the beginning of the purchase period or the end of each purchase period. Under the amended and restated ESPP, employees must hold the stock they purchase for a minimum of six months from the date of purchase. During 2020, employees purchased and we issued to employees 0.06 million shares under the ESPP at a weighted average price of $43.65 per share. At December 31, 2020, there were 0.7 million shares available for purchase under the ESPP. Stock Option Activity The following table summarizes the stock option activity under our stock plans for the year ended December 31, 2020 (in thousands, except per share and contractual life data): Number of Shares Weighted Average Exercise Price Per Share Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2019 11,001 $ 51.48 Granted 2,764 $ 59.89 Exercised (1,069 ) $ 40.88 Cancelled/forfeited/expired (361 ) $ 56.48 Outstanding at December 31, 2020 12,335 $ 54.14 4.16 $ 55,885 Exercisable at December 31, 2020 7,366 $ 52.45 3.16 $ 43,267 The weighted-average estimated fair values of options granted were $29.43, $28.76 and $25.49 for the years ended December 31, 2020, 2019 and 2018, respectively. The total intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 were $15.5 million, $83.8 million and $34.8 million, respectively, which we determined as of the date of exercise. The amount of cash received from the exercise of stock options was $43.7 million, $105.9 million and $18.9 million for the years ended December 31, 2020, 2019 and 2018, respectively. For the year ended December 31, 2020, the weighted-average fair value of options exercised was $55.33. As of December 31, 2020, total unrecognized compensation cost related to non-vested stock options was $54.1 million. We expect to recognize this cost over a weighted average period of 1.1 years. We will adjust the total unrecognized compensation cost for future changes in estimated forfeitures. Restricted Stock Unit Activity The following table summarizes the RSU activity for the year ended December 31, 2020 (in thousands, except per share data): Number of Shares Weighted Average Grant Date Fair Value Per Share Non-vested at December 31, 2019 1,866 $ 55.80 Granted 1,244 $ 60.86 Vested (602 ) $ 53.68 Cancelled/forfeited (134 ) $ 58.96 Non-vested at December 31, 2020 2,374 $ 58.81 For the years ended December 31, 2020, 2019 and 2018, the weighted-average grant date fair value of RSUs granted was $60.86, $60.23 and $51.06 per RSU, respectively. As of December 31, 2020, total unrecognized compensation cost related to RSUs was $55.3 million. We expect to recognize this cost over a weighted average period of 1.3 years. We will adjust the total unrecognized compensation cost for future changes in estimated forfeitures. Stock-based Compensation Expense and Valuation Information The following table summarizes stock-based compensation expense for the years ended December 31, 2020, 2019 and 2018 (in thousands): Year Ended December 31, 2020 2019 2018 Cost of products sold $ 1,991 $ 438 $ 160 Research, development and patent 115,584 95,348 76,557 Selling, general and administrative 112,542 50,788 54,595 Total $ 230,117 $ 146,574 $ 131,312 Our non-cash stock-based compensation expense included of stock-based compensation expense for Akcea employees for the years ended December 31, 2020, 2019 and 2018, respectively. In October 2020, as part of the Akcea Acquisition, Akcea’s outstanding equity awards vested under Akcea’s Plan. As a result, in the fourth quarter of 2020, we recognized all unrecognized stock-based compensation ($59.3 million) under Akcea’s Plan. See Note 7, Akcea Acquisition In the third quarter of 2019, Akcea executive officers terminated their employment and entered into separation agreements with Akcea. As a result, in the third quarter of 2019, Akcea reversed $ million of stock-based compensation expense it had previously recognized related to the executive officers’ stock options and RSUs that were no longer going to vest. Determining Fair Value Valuation. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP. The expected term of stock options granted represents the period of time that we expect them to be outstanding. We estimate the expected term of options granted based on actual and projected exercise patterns. We recognize compensation expense for stock options granted, RSUs, and stock purchase rights under the ESPP using the accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period. For the years ended December 31, 2020, 2019 and 2018, we used the following weighted-average assumptions in our Black-Scholes calculations: Ionis Employee Stock Options: December 31, 2020 2019 2018 Risk-free interest rate 1.5 % 2.3 % 2.4 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 58.6 % 60.3 % 63.0 % Expected life 4.7 years 4.8 years 4.6 years Ionis Board of Director Stock Options: December 31, 2020 2019 2018 Risk-free interest rate 0.5 % 1.9 % 2.8 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 57.6 % 60.7 % 61.5 % Expected life 6.7 years 6.6 years 6.6 years Ionis ESPP: December 31, 2020 2019 2018 Risk-free interest rate 0.8 % 2.4 % 1.8 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 47.9 % 45.6 % 47.3 % Expected life 6 months 6 months 6 months Risk-Free Interest Rate.

In addition to our stock plans, Akcea had its own stock plan prior to the Akcea Acquisition, referred to as the Akcea 2015 Equity Incentive Plan, or Akcea Plan. Under the Akcea Plan, Akcea granted options and RSUs. For the years ended December 31, 2020, 2019 and 2018, we used the following weighted-average assumptions in our Black-Scholes calculations for the Akcea Plan: Akcea Employee Stock Options: December 31, 2020 2019 2018 Risk-free interest rate 1.1 % 2.2 % 2.8 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 75.0 % 75.4 % 77.1 % Expected life 6.08 years 6.09 years 6.08 years Akcea Board of Director Stock Options: December 31, 2020 2019 2018 Risk-free interest rate 0.8 % 1.8 % 2.9 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 75.3 % 73.8 % 78.2 % Expected life 5.67 years 6.25 years 6.42 years Akcea ESPP: December 31, 2020 2019 2018 Risk-free interest rate 1.0 % 2.4 % 1.9 % Dividend yield 0.0 % 0.0 % 0.0 % Volatility 71.9 % 60.0 % 64.2 % Expected life 6 months 6 months 6 months The following summarizes the Black-Scholes input methodology for Akcea options that differs from the methodology we use for Ionis options: Volatility.

Significant components of our deferred tax assets and liabilities as of December 31, 2020 and 2019 are as follows (in thousands): Year Ended December 31, 2020 2019 Deferred Tax Assets: Net operating loss carryovers $ 83,681 $ 20,191 Tax credits 245,746 210,455 Deferred revenue 124,452 127,763 Stock-based compensation 80,055 65,703 Intangible and capital assets 98,443 77,861 Other 13,402 12,510 Total deferred tax assets $ 645,779 $ 514,483 Deferred Tax Liabilities: Convertible debt $ (2,920 ) $ (6,110 ) Fixed assets (3,611 ) (1,958 ) Other (5,808 ) (3,884 ) Net deferred tax asset $ 633,440 $ 502,531 Valuation allowance (633,440 ) (196,974 ) Total net deferred tax assets and liabilities $ — $ 305,557 We evaluate our deferred tax assets regularly to determine whether adjustments to the valuation allowance are appropriate due to changes in facts or circumstances, such as changes in expected future pre-tax earnings, tax law, interactions with taxing authorities and developments in case law. In making this evaluation, we rely on our recent history of pre-tax earnings. Our material assumptions are our forecasts of future pre-tax earnings and the nature and timing of future deductions and income represented by the deferred tax assets and liabilities, all of which involve the exercise of significant judgment. Although we believe our estimates are reasonable, we are required to use significant judgment in determining the appropriate amount of valuation allowance recorded against our deferred tax assets. Ionis and Akcea have filed separate U.S. federal income tax returns since Akcea’s IPO in 2017. Accordingly, we were required to assess our Ionis stand-alone and Akcea’s valuation allowances separately even though we consolidate Akcea’s financial results in our consolidated financial statements. However, as a result of the Akcea acquisition, Ionis and Akcea will file a consolidated U.S. federal income tax return beginning in the fourth quarter of 2020, and we therefore assessed our U.S. federal valuation allowance requirements on a consolidated basis as of that period. We continue to assess the state portion of our valuation allowance on a consolidated basis. We assessed our valuation allowance requirements and recorded a valuation allowance of $313 million against all of Ionis’ U.S. federal net deferred tax assets in the fourth quarter of 2020, due to uncertainties related to our ability to realize the tax benefits associated with these assets. This determination is based largely on Akcea rejoining the Ionis U.S. consolidated federal tax group in the fourth quarter of 2020. Due to Akcea’s historical and projected financial statement losses, and the negative impact this is expected to have on Ionis’ consolidated taxable income, there is uncertainty of generating sufficient consolidated pre-tax income in future periods to realize the Ionis deferred tax benefits. It is also expected that Ionis’ pre-tax income in future periods may be lower due to increased research and development expenses associated with our pipeline of wholly owned medicines. We now maintain a valuation allowance against all our consolidated U.S. federal and state net deferred tax assets. Our valuation allowance increased by $436 million from December 31, 2019 to December 31, 2020. $313 million of the increase related to the valuation allowance established against our beginning of the year balance of Ionis’ U.S. federal net deferred tax assets as discussed above, which resulted in us recognizing income tax expense during 2020. The remaining increase in our valuation allowance related to current year changes in our net deferred tax assets. At December 31, 2020, we had federal and state, primarily California, tax net operating loss carryforwards of $243.3 million and $346.3 million, respectively. Our federal tax loss carryforwards are available indefinitely. Our California tax loss carryforwards will begin to expire in 2031. At December 31, 2020, we also had federal and California research and development tax credit carryforwards of $210.5 million and $87.4 million, respectively. Our Federal research and development tax credit carryforwards will begin to expire in 2034. Our California research and development tax credit carryforwards are available indefinitely. Utilization of the net operating loss and tax credit carryforwards may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. We analyze filing positions in all U.S. federal, state and foreign jurisdictions where we file income tax returns, and all open tax years in these jurisdictions to determine if we have any uncertain tax positions on any of our income tax returns. We recognize the impact of an uncertain tax position on an income tax return at the largest amount that the relevant taxing authority is more-likely-than not to sustain upon audit. We do not recognize uncertain income tax positions if they have less than 50 percent likelihood of the applicable tax authority sustaining our position. The following table summarizes our gross unrecognized tax benefits (in thousands): Year Ended December 31, 2020 2019 2018 Beginning balance of unrecognized tax benefits $ 69,784 $ 68,301 $ 78,014 Decrease for prior period tax positions (24,154 ) (867 ) (12,814 ) Increase for prior period tax positions 7,023 736 — Increase for current period tax positions 1,510 1,614 3,101 Ending balance of unrecognized tax benefits $ 54,163 $ 69,784 $ 68,301 Included in the balance of unrecognized tax benefits at December 31, 2020 and 2019 was $6.4 million and $0.4 million respectively, that if we recognized, could impact our effective tax rate, subject to our remaining valuation allowance. None of our unrecognized tax benefits recorded at December 31, 2018 would impact our effective tax rate, if we recognized them. We do not foresee any material changes to our gross unrecognized tax benefits within the next twelve months. We recognize interest and/or penalties related to income tax matters in income tax expense. During the year ended December 31, , we recognized $ million of accrued interest and penalties related to gross unrecognized tax benefits We are subject to taxation in the U.S. and various state and foreign jurisdictions. Our tax years for 1999 through 2019 are subject to examination by the U.S. federal, state and foreign tax authorities. We do not provide for a U.S. income tax liability and foreign withholding taxes on undistributed foreign earnings of our foreign subsidiaries as we consider those earnings to be permanently reinvested. It is not practicable for us to calculate the amount of unrecognized deferred tax liabilities associated with these earnings. |

Collaborative Arrangements and Licensing Agreements [Abstract] | |
Collaborative Arrangements and Licensing Agreements | 6. Collaborative Arrangements and Licensing Agreements Strategic Partnership Biogen We have several strategic collaborations with Biogen focused on using antisense technology to advance the treatment of neurological disorders. These collaborations combine our expertise in creating antisense medicines with Biogen’s expertise in developing therapies for neurological disorders. We developed and licensed to Biogen SPINRAZA, our approved medicine to treat people with spinal muscular atrophy, or SMA. We and Biogen are currently developing eight investigational medicines to treat neurodegenerative diseases under these collaborations, including medicines in development to treat people with ALS, Alzheimer’s disease Spinal Muscular Atrophy Collaborations SPINRAZA In January 2012, we entered into a collaboration agreement with Biogen to develop and commercialize SPINRAZA, an RNA-targeted therapy for the treatment of SMA. From inception through December 2020, we earned more than $ billion in total revenue under our SPINRAZA collaboration, including more than $ million in revenue from SPINRAZA royalties and more than $ million in R&D revenue. We are receiving tiered royalties ranging from to on net sales of SPINRAZA. We have exclusively in-licensed patents related to SPINRAZA from Cold Spring Harbor Laboratory and the University of Massachusetts. We pay Cold Spring Harbor Laboratory and the University of Massachusetts a low single digit royalty on net sales of SPINRAZA. Biogen is responsible for all global development, regulatory and commercialization activities and costs for SPINRAZA. We completed our performance obligations under our collaboration in 2016 New antisense medicines for the treatment of SMA In December 2017, we entered into a collaboration agreement with Biogen to new antisense medicines for the treatment of SMA . Biogen has the option to license therapies arising out of this collaboration following the completion of preclinical studies. Upon licensing, Biogen will be responsible for global development, regulatory and commercialization activities and costs for such therapies . Under the collaboration agreement, we received a upfront payment in the fourth quarter of 2017. We will receive development and regulatory milestone payments from Biogen if new medicines advance towards marketing approval. In total over the term of our collaboration, we are eligible to receive up to $ billion in license fees, milestone payments and other payments, including up to $ million for the achievement of development milestones, up to $ million for the achievement of commercialization milestones and up to $ million for the achievement of sales milestones. In addition, we are eligible to receive tiered royalties from the mid-teens to mid- range on net sales. We will achieve the next payment of up to $ million for the license of a medicine under this collaboration. At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for Biogen. We determined the transaction price to be the $25 million upfront payment we received when we entered into the collaboration. We allocated the transaction price to our single performance obligation. In the fourth quarter of 2019, we completed our R&D services performance obligation under this collaboration. We recognized revenue as we performed services based on our effort to satisfy our performance obligation relative to the total effort expected to satisfy our performance obligation. We completed our performance obligation earlier than we previously estimated, as a result, we recognized $8.3 million of additional revenue in the fourth quarter of 2019. We do not have any remaining performance obligations under this collaboration. We will receive development and regulatory milestone payments from Biogen if Biogen advances the development candidate under this collaboration toward marketing approval. Neurology Collaborations 2018 Strategic Neurology In April 2018, we and Biogen entered into a strategic collaboration to develop novel antisense medicines for a broad range of neurological diseases and entered into a SPA. As part of the collaboration, Biogen gained exclusive rights to the use of our antisense technology to develop therapies for these diseases for years. We are responsible for the identification of antisense drug candidates based on selected medicines Biogen will have the option to license the selected medicine If Biogen exercises its option to license a medicine, it will assume global development, regulatory and commercialization responsibilities and costs for that medicine. In the second quarter of 2018, we received We are eligible to receive up to $ million in milestone payments for each medicine that achieves marketing approval. up to the on net sales. W under this collaboration. At the commencement of this collaboration, We determined our transaction price to be $ million, comprised of $ million from the upfront payment and $ million for the premium paid by Biogen for its purchase of our common stock. From inception through December 2020, we have included $608 million in payments in the transaction price for our R&D services performance obligation under this collaboration, including $ million of milestone payments we achieved in 2020 and $ million of milestone payments we achieved in 2019. These milestone payments did not create new performance obligations because they are part of our original R&D services performance obligation. Therefore, we included these amounts in our transaction price for our R&D services performance obligation in the period we achieved the milestone payment. We are recognizing revenue for our R&D services performance obligation as we perform services based on our effort to satisfy our performance obligation relative to our total effort expected to satisfy our performance obligation. We currently estimate we will satisfy our performance obligation at the end of the contractual term in June 2028. 2013 Strategic Neurology In September 2013, we and Biogen entered into a long-term strategic relationship focused on applying antisense technology to advance the treatment of neurodegenerative diseases. As part of the collaboration, Biogen gained exclusive rights to the use of our antisense technology to develop therapies for neurological diseases and has the option to license medicines resulting from this collaboration. We will usually be responsible for drug discovery and early development of antisense medicines and Biogen will have the option to license antisense medicines after Phase 2 proof-of-concept. In October 2016, we expanded our collaboration to include additional research activities we will perform. If Biogen exercises its option to license a medicine, it will assume global development, regulatory and commercialization responsibilities and costs for that medicine. We are currently advancing six investigational medicines in development under this collaboration, including a Rx a a Under the terms of the agreement, we received an upfront payment of $100 million and are eligible to receive milestone payments, license fees and royalty payments for all medicines developed under this collaboration, with the specific amounts dependent upon the modality of the molecule advanced by Biogen. For each antisense molecule that is chosen for drug discovery and development under this collaboration, we are eligible to receive up to approximately $260 million in a license fee and milestone payments per program. The $260 million per program consists of approximately $60 million in development milestones, including amounts related to the cost of clinical trials, and up to $130 million in milestone payments if Biogen achieves pre-specified regulatory milestones. In addition, we are eligible to receive tiered royalties up to the mid-teens on net sales from any antisense medicines developed under this collaboration. From inception through December 2020, we have received over $270 million in upfront fees, milestone payments and other payments under this collaboration. We will achieve the next payment of up to $10 million if we advance a program under this collaboration. At the commencement of our 2013 strategic neurology collaboration, we identified one performance obligation, which was to perform R&D services for Biogen. At inception, we determined the transaction price to be the $100 million upfront payment we received and allocated it to our single performance obligation. As we achieve milestone payments for our R&D services, we include these amounts in our transaction price for our R&D services performance obligation. We recognized revenue for our R&D services performance obligation based on our effort to satisfy our performance obligation relative to our total effort expected to satisfy our performance obligation . research and development services and recognized the remaining revenue related to this performance obligation. 2020 Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter we generated the payment because we did not have any performance obligations for the respective payment. The following are the payments we earned: ● In the third quarter of 2018, we earned a $10 million milestone payment when Biogen initiated a Phase 1 study of IONIS-C9 Rx ● In the fourth quarter of 2018, we earned a $35 million license fee when Biogen licensed tofersen from us because Biogen had full use of the licenses without any continuing involvement from us. ● In the fourth quarter of 2018, we earned a $ million milestone when Biogen initiated a Proof-of-Concept study for tofersen. ● In the third quarter of 2019, we earned an $8 million milestone payment when Biogen initiated a Phase 1/2 study of ION859 for the treatment of people with Parkinson’s disease ● In the fourth quarter of 2019, we earned a $10 million milestone payment when Biogen advanced IONIS-C9 Rx ● In the third quarter of 2020, we earned $18 million in milestone payments when Biogen initiated a Phase 1/2 trial for ION464, an investigational medicine in development targeting alpha-synuclein to treat patients with multiple system atrophy. ● In the third quarter of 2020, w e earned a $ million milestone payment when Biogen initiated a Phase 1/2 trial for ION541, an investigational medicine in development targeting ataxin 2 to treat patients with ALS. 2012 Neurology In December 2012, we and Biogen entered into a collaboration agreement to develop and commercialize novel antisense medicines to treat neurodegenerative diseases. We are responsible for the development of each of the medicines through the completion of the initial Phase 2 clinical study for such medicine. Biogen has the option to license a medicine from each of the programs through the completion of the first Phase 2 study for each program. Under this collaboration, we are currently advancing IONIS-MAPT Rx Rx Rx Under the terms of the agreement, we received an upfront payment of $ million. Over the term of the collaboration, we are eligible to receive up to $ million in a license fee and milestone payments per program, plus a mark-up on the cost estimate of the Phase 1 and 2 studies. The $ million per program consists of up to $ million in development milestone payments, plus a mark-up on the cost estimate of the Phase 1 and 2 studies and up to $ million in milestone payments if Biogen achieves pre-specified regulatory milestones. In addition, we are eligible to receive tiered royalties up to the mid-teens on net sales of any medicines resulting from each of the programs. From inception through December 2020, we have received $ million in payments under this collaboration, including $ million we received from Biogen for achieving milestones for advancing IONIS-MAPT Rx during 2020. We will achieve the next payment of $ Rx Under our collaboration, we determined we had a performance obligation to perform R&D services. We allocated $40 million in total payments to the transaction price for our R&D services performance obligation. In the third quarter of 2019, we completed our R&D services performance obligation when we designated a development candidate and Biogen accepted the development candidate. Biogen’s decision to accept the development candidate was not within our control. We were recognizing revenue as we performed services based on our effort to satisfy our performance obligation relative to the total effort expected to satisfy our performance obligation. Because Biogen accepted the development candidate earlier than when we were previously estimating, we recognized $6.3 million of accelerated revenue in the third quarter of 2019. When we commenced development for IONIS-MAPT Rx Rx Rx Rx ● In the second quarter of 2019, we achieved a $7.5 million milestone payment from Biogen when we advanced IONIS-MAPT Rx ● In the fourth quarter of 2019, we achieved a $12 million milestone payment from Biogen when we entered into an agreement to conduct a long-term extension study for IONIS-MAPT Rx ● In the first quarter of 2020, we achieved a $7.5 million milestone payment from Biogen when we advanced IONIS-MAPT Rx ● In the third quarter of 2020, we achieved a $12 million milestone payment from Biogen when we advanced IONIS-MAPT Rx Rx In the fourth quarter of 2019, we identified another performance obligation upon Biogen’s license of IONIS-MAPT Rx Rx In the fourth quarter of 2019, we earned a $ million milestone payment when Biogen advanced ION582. We recognized this milestone payment in full in the fourth quarter of 2019 because we did not have any performance obligations related to this milestone payment. During the years ended December 31, 2020, 2019 and 2018, we earned the following revenue from our relationship with Biogen (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 SPINRAZA royalties (commercial revenue) $ 286.6 $ 293.0 $ 237.9 R&D revenue 122.0 180.6 137.1 Total revenue from our relationship with Biogen $ 408.6 $ 473.6 $ 375.0 Percentage of total revenue 56 % 42 % 63 % Our December 31, and included deferred revenue of $ million and $ million, respectively, related to our relationship with Biogen. Research, Development and Commercialization Partners AstraZeneca We have two collaborations with AstraZeneca, one focused on the treatment of cardiovascular, renal and metabolic diseases and a second nonalcoholic steatohepatitis, or NASH, and cancer Cardiovascular, Renal and Metabolic Diseases Collaboration In July 2015, we and AstraZeneca formed a collaboration to discover and develop antisense therapies for treating cardiovascular, renal and metabolic diseases. Under our collaboration, AstraZeneca has licensed four medicines from us: ● ION449 (formerly IONIS-AZ4-2.5-L Rx ● ION532, an investigational medicine we designed to reduce the production of APOL1 for the ● ION839, an investigational medicine we designed to ; and ● ION455, an investigational medicine we designed as a potential treatment for NASH. AstraZeneca is responsible for global development, regulatory and commercialization activities and costs for each of the medicines it has licensed and any medicines AstraZeneca licenses in the future. Under the terms of the agreement, we received a $65 million upfront payment. We are eligible to receive license fees and milestone payments of up to more than $5.5 billion as medicines under this collaboration advance, including up to $1.1 billion for the achievement of development milestones, up to $2.9 billion for regulatory milestones and up to $1.5 billion for commercial milestones. In addition, we are eligible to receive tiered royalties up to the low teens on net sales from any product that AstraZeneca successfully commercializes under this collaboration agreement. We will achieve the next payment of up to $30 million under this collaboration if AstraZeneca advances a medicine under this collaboration . At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for AstraZeneca. We determined the transaction price to be the $65 million upfront payment we received and we allocated it to our single performance obligation. We are recognizing revenue for our R&D services performance obligation as we perform services based on our effort to satisfy this performance obligation relative to our total effort expected to satisfy our performance obligation. We currently estimate we will satisfy this performance obligation in 2020 Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter we generated the payment because the payments were distinct and we did not have any performance obligations for the respective payment. The following are the payments we have earned: ● In the first quarter of 2018, we earned ● In the third quarter of 2018, we earned a $10 million milestone payment when AstraZeneca initiated a Phase 1 study of ION449. ● In the fourth quarter of 2019, we earned a $10 million milestone payment when AstraZeneca initiated a Phase 1 study of ION839. ● In the first quarter of 2020, we earned a $10 million milestone payment when AstraZeneca advanced ION532. ● In the fourth quarter of 2020, we earned a $20 million milestone payment when AstraZeneca advanced ION449. ● In the fourth quarter of 2020, we earned a Oncology Collaboration In December 2012, we entered into a collaboration agreement with AstraZeneca to discover and develop antisense medicines to treat cancer. We and AstraZeneca also established an oncology research program. AstraZeneca has the option to license medicines resulting from the program, and if AstraZeneca exercises its option to license a medicine, it will be responsible for global development, regulatory and commercialization activities and costs for such medicine. In 2020, AstraZeneca licensed ION736, an investigational medicine in development targeting FOXP3 for the treatment of cancer. Under the terms of this agreement, we received $ million in upfront payments. We are eligible to receive milestone payments and license fees up to more than $ million under this collaboration, including up to $ million for the achievement of development milestones and up to $ million for the achievement of regulatory milestones. In addition, we are eligible to receive tiered royalties up to the low teens on net sales from any product that AstraZeneca successfully commercializes under this collaboration agreement. From inception through December 2020, we have received over $ million in upfront fees, milestone payments, and other payments under this oncology collaboration, including $ million we earned when AstraZeneca licensed will achieve the next payment of $ million if AstraZeneca advances ION736 in development. We completed all of the performance obligations we identified under this collaboration in the first quarter of 2018. Under this collaboration, we have also generated additional payments that we concluded were not part of other performance obligations discussed above. We recognized each of these payments in full in the respective quarter we generated the payment because the payments were distinct and we did not have any performance obligations for the respective payment. The following are the payments we have earned: ● In the fourth quarter of 2018, we earned a $17.5 million milestone payment and a $10 million milestone payment when AstraZeneca advanced two programs under our collaboration. ● In the second quarter of 2020, we earned a $ million license fee when AstraZeneca licensed ION736 During the years ended December 31, 2020, 2019 and 2018, we earned the following revenue from our relationship with AstraZeneca (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 R&D revenue $ 88.0 $ 28.1 $ 120.7 Percentage of total revenue 12 % 3 % 20 % Our December 31, and included deferred revenue of $ million and $ million, respectively, related to our relationship with AstraZeneca. Bayer In May 2015, we entered into an exclusive license agreement with Bayer to develop and commercialize IONIS-FXI Rx Rx Rx Rx Rx We are eligible to receive up to $385 million in license fees, milestone payments and other payments, including up to $125 million for the achievement of development milestones and up to $110 million for the achievement of commercialization milestones. In addition, we are eligible to receive tiered royalties in the low to high 20 percent range on gross margins of both medicines combined. From inception through December 2020, we have received over $185 million from this collaboration. We will achieve the next payment of $20 million if Bayer initiates a Phase 3 study for the FXI program. At the commencement of this collaboration, we identified three performance obligations, the license of IONIS-FXI Rx In February 2017, when we amended our collaboration with Bayer, we identified two new performance obligations , for the license of IONIS-FXI-L Rx and for R&D services the license of IONIS-FXI-L Rx based on its estimated relative stand-alone selling price and recognized the associated revenue upon our delivery of the license in the first quarter of 2017. We allocated $ million to our R&D services performance obligation based on an estimated relative stand-alone selling price. In the fourth quarter of 2019, we earned a $10 million milestone payment when Bayer decided it would advance IONIS-FXI-L Rx During the years ended December 31, 2020, 2019 and 2018, we earned the following revenue from our relationship with Bayer (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 R&D revenue $ 3.2 $ 14.3 $ 5.0 Percentage of total revenue 0 % 1 % 1 % Our consolidated balance sheet at December 31, did t include any deferred revenue related to our relationship with Bayer. Our December 31, included deferred revenue of $ million related to our relationship with Bayer. GSK In March 2010, we entered into an alliance with GSK using our antisense drug discovery platform to discover and develop new medicines against targets for serious and rare diseases, including infectious diseases and some conditions causing blindness. Under the terms of the agreement, we received upfront payments of $35 million. Our collaboration with GSK currently includes two medicines targeting hepatitis B virus, or HBV: IONIS-HBV Rx Rx Under our agreement, if GSK successfully develops these medicines and achieves pre-agreed sales targets, we could receive license fees and milestone payments of up to $262 million, including up to $47.5 million for the achievement of development milestones, up to $120 million for the achievement of regulatory milestones and up to $70 million for the achievement of commercialization milestones. In addition, we are eligible to receive tiered royalties up to the mid-teens on net sales from any product that GSK successfully commercializes under this alliance. From inception through December 2020, we have received more than $190 million in payments under this alliance with GSK. We will achieve the next payment of $15 million if GSK initiates a Phase 3 study of a medicine under this program. We completed our R&D services performance obligations under our collaboration in the first quarter of 2015. We do not have any remaining performance obligations under our collaboration with GSK; however, we can still earn additional payments and royalties as GSK advances the HBV program. During the years ended December 31, 2020, 2019 and 2018, we earned the following revenue from our relationship with GSK (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 R&D revenue $ 0.2 $ 25.4 $ 1.6 Percentage of total revenue 0 % 2 % 0 % We did not have any deferred revenue from our relationship with GSK at December 31, 2020 and 2019. Janssen Biotech, Inc. In December 2014, we entered into a collaboration agreement with Janssen Biotech, Inc. to discover and develop antisense medicines that can be locally administered, including oral delivery, to treat autoimmune disorders of the GI tract. Under our collaboration, Janssen is currently advancing ION253 for the treatment of immune-mediated GI disease. Janssen licensed ION253 in the fourth quarter of 2017. Prior to Janssen’s license of ION253, we were responsible for the discovery activities to identify development candidates. Under the agreement, Janssen is responsible for global development, regulatory and commercialization activities and costs for ION253. Under the terms of the agreement, we received $35 million in upfront payments. We are eligible to receive up to more than $285 million in license fees and milestone payments for these programs, including up to $65 million for the achievement of development milestones, up to $160 million for the achievement of regulatory milestones and up to $60 million for the achievement of commercialization milestones. From inception through December 2020, we have received over $80 million from this collaboration. In addition, we are eligible to receive tiered royalties up to the near teens on net sales from any medicines resulting from this collaboration. We will achieve the next payment of $5 million if Janssen continues to advance ION253 in development. At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for Janssen. We determined the transaction price to be the $35 million upfront payments we received. We allocated the $ million Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter in which we generated the payment because the payments were distinct and we did not have any performance obligations for the respective payment. In the third quarter of 2020, we earned a $ million milestone payment when Janssen initiated a Phase 1 trial for ION253 During the years ended December 31, 2020, 2019 and 2018, we earned the following revenue from our relationship with Janssen (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 R&D revenue $ 5.0 $ 0.1 $ 6.6 Percentage of total revenue 1 % 0 % 1 % We did not have any deferred revenue from our relationship with Janssen at December 31, 2020 and 2019. Novartis In January 2017, we initiated a collaboration with Novartis to develop and commercialize pelacarsen and IONIS-APOCIII-L Rx . In the first quarter of 2019, Novartis licensed pelacarsen When Novartis decided to not exercise its option for Rx Rx Under the collaboration, we are eligible to receive up to $675 million in milestone payments, including $25 million for the achievement of a development milestone, up to $290 million for the achievement of regulatory milestones and up to $360 million for the achievement of commercialization milestones. From inception through December 2020, we have received $ million in upfront payments, milestone payments, license fees and other payments from this collaboration. We will achieve the next payment of $ million if Novartis advances pelacarsen. In conjunction with this collaboration, we entered into a SPA with Novartis. As part of the SPA, Novartis purchased 1.6 million shares of our common stock for $100 million in the first quarter of 2017. As part of the SPA, Novartis was required to purchase $50 million of Akcea’s common stock at Akcea’s IPO price or our common stock at a premium if an IPO did not occur by April 2018. Under the SPA, in the second quarter of 2017, Novartis purchased $50 million of Akcea’s common stock in a separate private placement concurrent with the completion of Akcea’s IPO at a price per share equal to the IPO price. At the commencement of this collaboration, we identified four separate performance obligations: ● R&D services for pelacarsen; ● R&D services for IONIS-APOCIII-L Rx ● API for pelacarsen; and ● API for IONIS-APOCIII-L Rx We determined that the R&D services for each medicine and the API for each medicine were distinct performance obligations. We determined our transaction price to be $108.4 million, comprised of the following: ● $75 million from the upfront payment; ● $28.4 million for the premium paid by Novartis for its purchase of our common stock at a premium in the first quarter of 2017; and ● $5.0 million for the potential premium Novartis would have paid if they purchased our common stock in the future. We allocated the transaction price based on the estimated stand-alone selling price of each performance obligation as follows: ● $ million for the R&D services for pelacarsen; ● $40.1 million for the R&D services for IONIS-APOCIII-L Rx ● $ 1.5 ● $ 2.8 Rx We recognized revenue related to each of the performance obligations as follows: ● We completed our R&D services performance obligation for pelacarsen ● We completed our R&D services performance obligation for IONIS-APOCIII-L Rx Rx Rx ● We recognized the amount attributed to pelacarsen API when we delivered it to Novartis in 2017; and ● We recognized the amount attributed to IONIS-APOCIII-L Rx We recognized revenue related to the R&D services for pelacarsen and IONIS-APOCIII-L Rx performance obligations as we performed services . During the years ended December 31, 2020 and 2019, we earned the following revenue from our relationship with Novartis (in millions, except percentage amounts): Year Ended December 31, 2020 2019 2018 R&D revenue $ 1.0 $ 187.4 $ 50.6 Percentage of total revenue 0 % 17 % 8 % We did not have any deferred revenue from our relationship with Novartis at December 31, 2020 and 2019. Pfizer In October 2019, we entered into a license agreement with Pfizer for vupanorsen, an investigational medicine in development to treat people with certain cardiovascular diseases. We completed a Phase 2 study of vupanorsen in patients NAFLD. Pfizer is responsible for all global development, regulatory and commercialization activities and costs for vupanorsen, subject to our right to co-commercialize in the U.S. and certain additional markets. Under the terms of the agreement, we received a $ million upfront payment. We are also eligible to receive development, regulatory and sales milestone payments of up to $ billion From inception through December 2020, we have received over $ million, including a $ million milestone payment we earned in the fourth quarter of 2020 when Pfizer began the Phase 2b study of vupanorsen. also eligible to earn tiered royalties in the mid-teens to low range on annual worldwide net sales. Prior to regulatory filing for marketing approval, we have the right, at our option to participate in certain commercialization activities with Pfizer in the U.S. and certain additional markets on pre-defined terms and based on meeting pre-defined criteria. We will achieve the next payment of $ million if Pfizer advances vupanorsen. At the commencement of the license agreement, we identified three separate performance obligations: ● License of vupanorsen; ● R&D services for vupanorsen; and ● API for vupanorsen. We determined the transaction price to be $250 million, the upfront payment we received. We ● $245.6 million for the license of vupanorsen; ● $ million for the R&D services for ; and ● $ million for the delivery of API. We are recognizing revenue related to each of our performance obligations as follows: ● We recognized $245.6 million for the license of vupanorsen in the fourth quarter of 2019 because we determined the license we granted to Pfizer was distinct from our other performance obligations and Pfizer had full use of the license without any continuing involvement from us. ● We recognized revenue related to the R&D services for as we performed services . We completed our R&D services in . ● We recognized the amount attributed to the API supply for when we delivered it to Pfizer in the fourth quarter of 2019. In the fourth quarter of 2020, we earned a $75 million milestone payment when Pfizer began the Phase 2b study of vupanorsen. We recognized this milestone payment in full in the fourth quarter of 2020 because we did not have any performance obligations related to this milestone payment. During the years ended December 31, 2020 and 2019, we earned the following revenue from our relationship with Pfizer (in millions, except percentage amounts): Year Ended December 31, 2020 2019 R&D revenue $ 82.1 $ 248.7 Percentage |

Akcea Acquisition [Abstract] | |
Akcea Acquisition | 7. Akcea Acquisition Purchase Price and Direct Transaction Costs Accounting for the Akcea Acquisition In October 2020, we acquired the shares of Akcea’s common stock we did not own, increasing our ownership from 76 percent to 100 percent. Under the purchase agreement, we purchased 24.8 million shares at $18.15 per share, resulting in a total purchase price of $450.6 million. To reflect our 100 percent ownership, we accounted for the increase in our ownership by eliminating the noncontrolling interest adjustment in stockholders’ equity in accordance with the Consolidation accounting guidance (ASC Topic 810). We recognized the difference between the purchase price and the adjustment to noncontrolling interest in stockholders’ equity as additional-paid-in capital. Refer to our Statement of Stockholders’ Equity We accounted for the transaction costs related to the Akcea Acquisition as a direct charge to stockholders’ equity. We incurred $40.6 million of direct transaction costs from the Akcea Acquisition, primarily comprised of banking and legal fees. Equity Award Payouts related to the Akcea Acquisition In October 2020, as part of the Akcea Acquisition, Ionis cancelled all of Akcea’s equity awards. In exchange for the cancelled awards, if eligible under the terms of the Acquisition, we paid holder’s a cash payment. We paid $ for each outstanding RSU. For each outstanding option with an exercise price less than $ , we paid $ less the exercise price. As a result, we paid out $ million in the fourth quarter of 2020 related to Akcea’s cancelled equity awards. We accounted for these payments as part of the transaction costs recorded to stockholders’ equity in the fourth quarter of 2020. Severance and Retention Costs related to the Akcea Acquisition As a result of the Akcea Acquisition, we expect to incur severance expenses of up to $9.3 million and retention expenses of up to $19.2 million. During the fourth quarter of 2020, we recorded $15.3 million of severance and retention related costs in operating expenses. We will recognize the remaining severance and retention costs through October 2021. The following table summarizes the costs by category related to the Akcea Acquisition (in millions): Three Months Ended December 31, 2020 R&D expenses $ 3.9 SG&A expenses 11.4 Total $ 15.3 The following table summarizes the severance and retention reserve included in accrued compensation for the period indicated related to Akcea Acquisition (in millions): Three Months Ended December 31, 2020 Severance & retention reserve beginning balance $ — Severance & retention expensed during period 15.3 Amounts paid during the period (0.6 ) Severance & retention reserve ending balance $ 14.7 |

Segment Information and Concentration of Business Risk | 9. Segment Information and Concentration of Business Risk Through 2020, we had two reportable segments, our Ionis Core segment and Akcea Therapeutics. We have provided segment financial information and results for our Ionis Core segment and our Akcea Therapeutics segment based on the segregation of revenues and expenses that our chief decision maker reviewed to assess operating performance and to make operating decisions through 2020. In our Ionis Core segment, we are exploiting our antisense technology to generate a broad pipeline of first-in-class and/or best-in-class medicines for us and our partners. Our Ionis Core segment generates revenue from a multifaceted partnering strategy. Akcea was . Akcea generated revenue from TEGSEDI and WAYLIVRA product sales and from its collaborations.

Legal Proceedings [Abstract] | |
Legal Proceedings | 11. Legal Proceedings From time to time, we are involved in legal proceedings arising in the ordinary course of our business. Periodically, we evaluate the status of each legal matter and assess our potential financial exposure. If the potential loss from any legal proceeding is considered probable and the amount can be reasonably estimated, we accrue a liability for the estimated loss. Significant judgment is required to determine the probability of a loss and whether the amount of the loss is reasonably estimable. The outcome of any proceeding is not determinable in advance. As a result, the assessment of a potential liability and the amount of accruals recorded are based only on the information available to us at the time. As additional information becomes available, we reassess the potential liability related to the legal proceeding, and may revise our estimates. On July 16, 2020, a purported stockholder of Akcea filed an action in the Delaware Court of Chancery captioned John Makris, et al. v. Stanley T. Crooke, et al., C.A. No. 2020-0587, or the “Delaware Action.” The plaintiff in the Delaware Action asserts claims against (i) current and former members of Akcea’s board of directors; and (ii) Ionis, or collectively, the “Defendants”. The plaintiff asserts derivative claims on behalf of Akcea, which is a nominal defendant in the Delaware Action, as well as putatively direct claims on behalf of a purported class of Akcea’s stockholders. The plaintiff in the Delaware action asserts that the Defendants breached their fiduciary duties in connection with the licensing transaction that we and Akcea entered into regarding TEGSEDI and IONIS-TTR-L Rx . The plaintiff also asserts an unjust enrichment claim against Ionis. The plaintiff’s claims are similar to those asserted in a prior action in the Delaware Court of Chancery captioned City of Cambridge Retirement System v. Crooke, et al., C.A. No. 2019-0905, which was dismissed with prejudice to the named plaintiff only on April 8, 2020. We believe that the claims asserted in the Delaware Action are without merit and anticipate filing a motion to dismiss the claims. In light of the August 31, 2020 public announcement of the Akcea Acquisition, the parties to the Delaware Action entered into a stipulation whereby the Defendants need to respond to the complaint filed on July 16, 2020, and the plaintiff will file an amended complaint. The amended complaint has not yet been filed. |

Basis of Presentation | Basis of Presentation In our consolidated financial statements we included the accounts of Ionis Pharmaceuticals, Inc. and the consolidated results of our subsidiary, Akcea Therapeutics, Inc. and its wholly owned subsidiaries (“we”, “us” or “our”). We formed Akcea in December 2014. In July 2017, Akcea completed an initial public offering, or IPO. Prior to Akcea’s IPO in July 2017, we owned of Akcea. In October 2020, we acquired the shares of Akcea’s common stock we did not own. We will refer to this transaction as the Akcea Acquisition throughout the remainder of this document. Akcea Acquisition We reflected changes in our ownership percentage in our financial statements as an adjustment to noncontrolling interest in the period the change occurred. |
Basic and Diluted Net Income (Loss) per Share | Basic and Diluted Net Income (Loss) per Share Basic net income (loss) per share We compute basic net income (loss) per share by dividing the total net income (loss) attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. The calculation of total net income (loss) attributable to our common stockholders for each year considered our net income (loss) for Ionis on a stand-alone basis plus our share of Akcea’s net income (loss) for the period. To calculate the portion of Akcea’s net income (loss) attributable to our ownership for each year, we multiplied Akcea’s income (loss) per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net income (loss) available to Ionis common stockholders for the calculation of net income (loss) per share is different than net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders in our consolidated statements of operations for each year. Our basic net income (loss) per share was calculated as follows (in thousands, except per share amounts): Year Ended December 31, 2020 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Loss Per Share Calculation Akcea’s net loss in the pre-acquisition period attributable to our ownership 77,095 $ (1.45 ) $ (111,775 ) Akcea’s net loss in the post-acquisition period attributable to our ownership (85,987 ) Akcea’s total net loss attributable to our ownership $ (197,762 ) Ionis’ stand-alone net loss (253,725 ) Net loss available to Ionis common stockholders $ (451,487 ) Weighted average shares outstanding 139,612 Basic net loss per share $ (3.23 ) Year Ended December 31, 2019 Weighted Average Shares Owned in Akcea Akcea s Net Income Per Share Basic Net Income Per Share Calculation Common shares 70,100 $ 0.49 $ 34,073 Akcea’s net income attributable to our ownership $ 34,073 Ionis’ stand-alone net income 262,490 Net income available to Ionis common stockholders $ 296,563 Weighted average shares outstanding 139,998 Basic net income per share $ 2.12 Year Ended December 31, 2018 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Income Per Share Calculation Common shares 59,812 $ (2.74 ) $ (163,938 ) Akcea’s net loss attributable to our ownership $ (163,938 ) Ionis’ stand-alone net income 440,806 Net income available to Ionis common stockholders $ 276,868 Weighted average shares outstanding 132,320 Basic net income per share $ 2.09 Diluted net income per share For the year ended December 31, 2020, we incurred a net loss; therefore, we did not include dilutive common equivalent shares in the computation of diluted net loss per share because the effect would have been anti-dilutive. Common stock from the following would have had an anti-dilutive effect on net loss per share: ● 0.125 percent convertible senior notes; ● 1 percent convertible senior notes; ● Dilutive stock options; ● Unvested restricted stock units, or RSUs; and ● Employee Stock Purchase Plan, or ESPP. For the years ended December 31, 2019 and 2018, we had net income available to Ionis common stockholders. As a result, we computed diluted net income per share using the weighted-average number of common shares and dilutive common equivalent shares outstanding during each period.

Revenue Recognition | Revenue Recognition Our Revenue Sources We generally recognize revenue when we have satisfied all contractual obligations and are reasonably assured of collecting the resulting receivable. We are often entitled to bill our customers and receive payment from our customers in advance of recognizing the revenue. In the instances in which we have received payment from our customers in advance of recognizing revenue, we include the amounts in deferred revenue on our consolidated balance sheet. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We earn commercial revenue primarily in the form of royalty payments on net sales of SPINRAZA. We will also recognize as commercial revenue sales milestone payments and royalties we earn under our other partnerships. Commercial Revenue: Product sales, net We added product sales from TEGSEDI to our commercial revenue in the fourth quarter of 2018 and we added product sales from WAYLIVRA to our commercial revenue in the third quarter of 2019. In Europe, through 2020 we sold TEGSEDI and WAYLIVRA to hospitals and pharmacies using 3PLs as distributors. Beginning in 2021, we are commercializing TEGSEDI and WAYLIVRA in Europe through a distribution agreement with Swedish Orphan Biovitrum AB, or Sobi, an international biopharmaceutical company that focuses on rare diseases. Under the terms of this agreement, we retained the marketing authorization for both medicines in Europe. In Latin America beginning in 2020, we sold TEGSEDI and WAYLIVRA to our partner, PTC Therapeutics. Under our collaboration agreement with PTC, PTC is commercializing TEGSEDI and WAYLIVRA in Latin America and Caribbean countries. Research and development revenue under collaborative agreements We often enter into collaboration agreements to license and sell our technology on an exclusive or non-exclusive basis. Our collaboration agreements typically contain multiple elements, or performance obligations, including technology licenses or options to obtain technology licenses, research and development, or R&D, services, and manufacturing services. We provide details about our collaboration agreements in Note 6, Collaborative Arrangements and Licensing Agreements. Steps to Recognize Revenue We use a five-step process to determine the amount of revenue we should recognize and when we should recognize it. The five step process is as follows: 1. Identify the contract Accounting rules require us to first determine if we have a contract with our partner, including confirming that we have met each of the following criteria: ● We and our partner approved the contract and we are both committed to perform our obligations; ● We have identified our rights, our partner’s rights and the payment terms; ● We have concluded that the contract has commercial substance, meaning that the risk, timing, or amount of our future cash flows is expected to change as a result of the contract; and ● We believe collectability of the consideration is probable. 2 . Identify the performance obligations We next identify our performance obligations, which represent the distinct goods and services we are required to provide under the contract. We typically have only one performance obligation at the inception of a contract, which is to perform R&D services. Often we enter into a collaboration agreement in which we provide our partner with an option to license a medicine in the future. We may also provide our partner with an option to request that we provide additional goods or services in the future, such as active pharmaceutical ingredient, or API. We evaluate whether these options are material rights at the inception of the agreement. If we determine an option is a material right, we will consider the option a separate performance obligation. Historically, we have concluded that the options we grant to license a medicine in the future or to provide additional goods and services as requested by our partner are not material rights because these items are contingent upon future events that may not occur and are not priced at a significant discount. When a partner exercises its option to license a medicine or requests additional goods or services, then we identify a new performance obligation for that item In some cases, we deliver a license at the start of an agreement. If we determine that our partner has full use of the license and we do not have any additional material performance obligations related to the license after delivery, then we consider the license to be a separate performance obligation. 3. Determine the transaction price We then determine the transaction price by reviewing the amount of consideration we are eligible to earn under the collaboration agreement, including any variable consideration. Under our collaboration agreements, consideration typically includes fixed consideration in the form of an upfront payment and variable consideration in the form of potential milestone payments, license fees and royalties. At the start of an agreement, our transaction price usually consists of only the upfront payment. We do not typically include any payments we may receive in the future in our initial transaction price because the payments are not probable and are contingent on certain future events. We reassess the total transaction price at each reporting period to determine if we should include additional payments in the transaction price. Milestone payments are our most common type of variable consideration. We recognize milestone payments using the most likely amount method because we will either receive the milestone payment or we will not, which makes the potential milestone payment a binary event. The most likely amount method requires us to determine the likelihood of earning the milestone payment. We include a milestone payment in the transaction price once it is probable we will achieve the milestone event. Most often, we do not consider our milestone payments probable until we or our partner achieve the milestone event because the majority of our milestone payments are contingent upon events that are not within our control and/ or are usually based on scientific progress which is inherently uncertain. For example, in the fourth quarter of 2020 , we earned milestone payment from AstraZeneca when AstraZeneca initiated a Phase 2 b study for ION 449 , our medicine in development targeting PCSK 9 to lower LDL-cholesterol. We did not consider the milestone payment probable until AstraZeneca achieved the milestone event because advancing ION 449 was contingent on AstraZeneca initiating a Phase 2 b study and was not within our control. We recognized the milestone payment in full in the period the milestone event was achieved because we did not have any remaining performance obligations related to the milestone payment 4. Allocate the transaction price Next, we allocate the transaction price to each of our performance obligations. When we have to allocate the transaction price to more than performance obligation, we make estimates of the relative stand-alone selling price of each performance obligation because we do not typically sell our goods or services on a stand-alone basis. We then allocate the transaction price to each performance obligation based on the relative stand-alone selling price. We do not reallocate the transaction price after the start of an agreement to reflect subsequent changes in stand-alone selling prices. We may engage a party, independent valuation specialist to assist us with determining a stand-alone selling price for collaborations in which we deliver a license at the start of an agreement. We estimate the stand-alone selling price of these licenses using valuation methodologies, such as the relief from royalty method. Under this method, we estimate the amount of income, net of taxes, for the license. We then discount the projected income to present value. The significant inputs we use to determine the projected income of a license could include ● Estimated future product sales; ● Estimated royalties we may receive from future product sales; ● Estimated contractual milestone payments we may receive; ● Expenses we expect to incur; ● Estimated income taxes; and ● A discount rate. We typically estimate the selling price of R&D services by using our internal estimates of the cost to perform the specific services. The significant inputs we use to determine the selling price of our R&D services include: ● The number of internal hours we estimate we will spend performing these services; ● The estimated cost of work we will perform; ● The estimated cost of work that we will contract with third parties to perform; and ● The estimated cost of API we will use. For purposes of determining the stand-alone selling price of the R&D services we perform and the API we will deliver, accounting guidance requires us to include a markup for a reasonable profit margin. 5. Recognize revenue We recognize revenue in of ways, over time or at a point in time. We recognize revenue over time when we are executing on our performance obligation over time and our partner receives benefit over time. For example, we recognize revenue over time when we provide R&D services. We recognize revenue at a point in time when our partner receives full use of an item at a specific point in time. For example, we recognize revenue at a point in time when we deliver a license or API to a partner. For R&D services that we recognize over time, we measure our progress using an input method. The input methods we use are based on the effort we expend or costs we incur toward the satisfaction of our performance obligation. We estimate the amount of effort we expend, including the time we estimate it will take us to complete the activities, or costs we incur in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that we multiply by the transaction price to determine the amount of revenue we recognize each period. This approach requires us to make numerous estimates and use significant judgement. If our estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that we recognize in the current and future periods. Collaborative Arrangements and Licensing Agreements The following are examples of when we typically recognize revenue based on the types of payments we receive. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We recognize royalty revenue, including royalties from SPINRAZA sales, in the period in which the counterparty sells the related product and recognizes the related revenue, which in certain cases may require us to estimate our royalty revenue Commercial Revenue: Product sales, net We recognize product sales in the period when our customer obtains control of our products, which occurs at a point in time upon transfer of title to the customer. We classify payments to customers or other parties in the distribution channel for services that are distinct and priced at fair value as selling, general and administrative, or SG&A, expenses in our consolidated statements of operations. Otherwise, payments to customers or other parties in the distribution channel that do not meet those criteria are classified as a reduction of revenue, as discussed further below. We exclude from revenues taxes collected from customers relating to product sales and remitted to governmental authorities Reserves for Product sales We record product sales at our net sales price, or transaction price. We include in our transaction price estimated reserves for discounts, returns, chargebacks, rebates and other allowances that we offer within contracts between us and our customers, wholesalers, health care providers and other indirect customers. We estimate our reserves using the amounts we have earned or what we can claim on the associated sales. We classify our reserves as a reduction of accounts receivable when we are not required to make a payment or as a current liability when we are required to make a payment. In certain cases, our estimates include a range of possible outcomes that are probability weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, our reserves reflect our best estimates under the terms of our respective contracts. When calculating our reserves and related product sales, we only recognize amounts to the extent that we consider it probable that we would not have to reverse in a future period a significant amount of the cumulative sales we previously recognized. The actual amounts we receive may ultimately differ from our reserve estimates. If actual amounts in the future vary from our estimates, we will adjust these estimates, which would affect our net product sales in the respective period The following are the components of variable consideration related to product sales: Chargebacks: In the U.S., we estimate obligations resulting from contractual commitments with the government and other entities to sell products to qualified healthcare providers at prices lower than the list prices charged to our U.S. customer. Our U.S. customer charges us for the difference between what it pays for the product and the selling price to the qualified healthcare providers. We also estimate the amount of chargebacks related to our estimated product remaining in the distribution channel at the end of the reporting period that we expect our customer to sell to healthcare providers in future periods. We record these reserves as a reduction to contracts receivable on our consolidated balance sheet Government rebates : We are subject to discount obligations under government programs, including Medicaid and Medicare programs in the U.S. and we record reserves for government rebates based on statutory discount rates and estimated utilization. We estimate Medicaid and Medicare rebates based on a range of possible outcomes that are probability weighted for the estimated payer mix. We record these reserves as an accrued liability on our consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. For Medicare, we also estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program. On a quarterly basis, we update our estimates and record any adjustments in the period that we identify the adjustments Managed care rebates: We are subject to rebates in connection with agreements with certain contracted commercial payers. We record these rebates as a liability on our consolidated balance sheet in the same period we recognize the related revenue. We estimate our managed care rebates based on our estimated payer mix and the applicable contractual rebate rate Trade discounts: We provide customary invoice discounts on product sales to our U.S. customer for prompt payment. We record this discount as a reduction of product sales in the period in which we recognize the related product revenue Distribution services We receive and pay for various distribution services from our U.S. and European customers (prior to our agreement with Sobi) and wholesalers in the U.S. We classify the costs for services we receive that are either not distinct from the sale of the product or for which we cannot reasonably estimate the fair value as a reduction of product sales. To the extent that the services we receive are distinct from the sale of the product, we classify the costs for such services as SG&A expenses. Product returns: Our U.S. customer has return rights and the wholesalers have limited return rights primarily related to the product’s expiration date. We estimate the amount of product sales that our customer may return. We record our return estimate as an accrued refund liability on our consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. Based on our distribution model for product sales, contractual inventory limits with our customer and wholesalers and the price of the product, we have had minimal returns to date and we believe we will continue to have minimal returns in the U.S. Our European customers generally only take title to the product after they receive an order and therefore they do not maintain excess inventory levels of our products. Accordingly, we have limited return risk in Europe and we do not estimate returns in Europe Research and development revenue under collaboration agreements: Upfront payments When we enter into a collaboration agreement with an upfront payment, we typically record the entire upfront payment as deferred revenue if our only performance obligation is for R&D services we will provide in the future. We amortize the upfront payment into revenue as we perform the R&D services. For example, under our collaboration agreement with Roche to develop IONIS-FB-L Rx for the treatment of complement-mediated diseases, we received a $ million upfront payment in the fourth quarter of 2018. We allocated the upfront payment to our single performance obligation, R&D services. We are amortizing the $ million upfront payment using an input method over the estimated period of time we are providing R&D services Milestone payments We are required to include additional consideration in the transaction price when it is probable. We typically include milestone payments for R&D services in the transaction price when they are achieved. We include these milestone payments when they are achieved because typically there is considerable uncertainty in the research and development processes that trigger these payments. Similarly, we include approval milestone payments in the transaction price once the medicine is approved by the applicable regulatory agency. We will recognize sales-based milestone payments in the period in which we achieve the milestone under the sales-based royalty exception allowed under accounting rules. We recognize milestone payments that relate to an ongoing performance obligation over our period of performance. For example, in the fourth quarter of 2020 , we achieved a million milestone payment from Biogen when we advanced a We added this payment to the transaction price and allocated it to our R&D services performance obligation. We are recognizing revenue related to this milestone payment over our estimated period of performance Conversely, we recognize in full those milestone payments that we earn based on our partners’ activities when our partner achieves the milestone event and we do not have a performance obligation. For example, in the third quarter of 2020, we recognized $18 million in milestone payments when Biogen initiated a Phase 1/2 trial for ION464, our medicine in development targeting alpha-synuclein to treat patients with multiple system atrophy We concluded that the milestone payments were not related to our R&D services performance obligation. Therefore, we recognized the milestone payments in full in the third quarter of 2020. License fees We generally recognize as revenue the total amount we determine to be the relative stand-alone selling price of a license when we deliver the license to our partner. This is because our partner has full use of the license and we do not have any additional performance obligations related to the license after delivery. For example, in the fourth quarter of 2020 , we earned a million license fee from AstraZeneca when AstraZeneca licensed ION 455 , an investigational medicine in development to treat nonalcoholic steatohepatitis, or NASH. Sublicense fees We recognize sublicense fee revenue in the period in which a party, who has already licensed our technology, further licenses the technology to another party because we do not have any performance obligations related to the sublicense. Amendments to Agreements From time to time we amend our collaboration agreements. When this occurs, we are required to assess the following items to determine the accounting for the amendment: 1) If the additional goods and/or services are distinct from the other performance obligations in the original agreement; and 2) If the goods and/or services are at a stand-alone selling price. If we conclude the goods and/or services in the amendment are distinct from the performance obligations in the original agreement and at a stand-alone selling price, we account for the amendment as a separate agreement. If we conclude the goods and/or services are not distinct and are sold at a stand-alone selling price, we then assess whether the remaining goods or services are distinct from those already provided. If the goods and/or services are distinct from what we have already provided, then we allocate the remaining transaction price from the original agreement and the additional transaction price from the amendment to the remaining goods and/or services. If the goods and/or services are not distinct from what we have already provided, we update the transaction price for our single performance obligation and recognize any change in our estimated revenue as a cumulative adjustment. For example, in May 2015, we entered into an exclusive license agreement with Bayer to develop and commercialize IONIS-FXI Rx for the prevention of thrombosis. As part of the agreement, Bayer paid us a $ million upfront payment. At the onset of the agreement, we were responsible for completing a Phase 2 study of IONIS-FXI Rx in people with end-stage renal disease on hemodialysis and for providing an initial supply of API. In February 2017, we amended our agreement with Bayer to advance IONIS-FXI Rx and to initiate development of IONIS-FXI-L Rx , which Bayer licensed. As part of the 2017 amendment, Bayer paid us $ million. We are also eligible to receive milestone payments and tiered royalties on gross margins of IONIS-FXI Rx and IONIS-FXI-L Rx . Under the 2017 amendment, we concluded we had a new agreement with performance obligations. These performance obligations were to deliver the license of IONIS-FXI-L Rx , to provide R&D services and to deliver API. We allocated the $ million transaction price to these performance obligations. Refer to Note 6, Collaborative Arrangements and Licensing Agreements , for further discussion of the Bayer collaboration. Multiple agreements From time to time, we may enter into separate agreements at or near the same time with the same partner. We evaluate such agreements to determine whether we should account for them individually as distinct arrangements or whether the separate agreements should be combined and accounted for together. We evaluate the following to determine the accounting for the agreements: ● Whether the agreements were negotiated together with a single objective; ● Whether the amount of consideration in one contract depends on the price or performance of the other agreement; or ● Whether the goods and/or services promised under the agreements are a single performance obligation. Our evaluation involves significant judgment to determine whether a group of agreements might be so closely related that accounting guidance requires us to account for them as a combined arrangement. For example, in the second quarter of 2018, we entered into two separate agreements with Biogen at the same time: a new strategic neurology collaboration agreement and a stock purchase agreement, or SPA. We evaluated the Biogen agreements to determine whether we should treat the agreements separately or combine them. We considered that the agreements were negotiated concurrently and in contemplation of one another. Based on these facts and circumstances, we concluded that we should evaluate the provisions of the agreements on a combined basis . |
Contracts Receivable | Contracts Receivable Our contracts receivable balance represents the amounts we have billed our partners or customers and that are due to us unconditionally for goods we have delivered or services we have performed. When we bill our partners or customers with payment terms based on the passage of time, we consider the contracts receivable to be unconditional. We typically receive payment within one quarter of billing our partner or customer |
Unbilled SPINRAZA Royalties | Unbilled SPINRAZA Royalties Our unbilled SPINRAZA royalties represent our right to receive consideration from Biogen in advance of when we are eligible to bill Biogen for SPINRAZA royalties. We include these unbilled amounts in other current assets on our consolidated balance sheet. |
Deferred Revenue | Deferred Revenue We are often entitled to bill our customers and receive payment from our customers in advance of our obligation to provide services or transfer goods to our partners. In these instances, we include the amounts in deferred revenue on our consolidated balance sheet. |
Cost of Products Sold | Cost of Products Sold Our cost of products sold includes manufacturing costs, transportation and freight costs and indirect overhead costs associated with the manufacturing and distribution of our products. We also may include certain period costs related to manufacturing services and inventory adjustments in cost of products sold. Prior to obtaining regulatory approval of TEGSEDI in July 2018 and WAYLIVRA in May 2019, we expensed as research and development expenses a significant portion of the costs we incurred to produce the initial commercial launch supply for each medicine. |
Research and Development Expenses | Our research and development expenses include wages, benefits, facilities, supplies, external services, clinical trial and manufacturing costs and other expenses that are directly related to our research and development operations. We expense research and development costs as we incur them. When we make payments for research and development services prior to the services being rendered, we record those amounts as prepaid assets on our consolidated balance sheet and we expense them as the services are provided. For the years ended December 31, 2020, 2019 and 2018, research and development expenses were $531.0 million, $461.5 million and $411.9 million, respectively. A portion of the costs included in research and development expenses are costs associated with our partner agreements. For the years ended December 31, 2020, 2019 and 2018, research and development costs of approximately $49.8 million, $83.2 million and $58.7 million, respectively, were related to our partner agreements. |
Patent Expenses | We capitalize costs consisting principally of outside legal costs and filing fees related to obtaining patents. We amortize patent costs over the useful life of the patent, beginning with the date the U.S. Patent and Trademark Office, or foreign equivalent, issues the patent. The weighted average remaining amortizable life of our issued patents was 10.3 years at December 31, 2020. The cost of our patents capitalized on our consolidated balance sheet at December 31, 2020 and 2019 was $37.0 million and $34.0 million, respectively. Accumulated amortization related to patents was $9.1 million and $8.3 million at December 31, 2020 and 2019, respectively. Based on our existing patents, we estimate amortization expense related to patents in each of the next five years to be the following: Year Ending December 31, Amortization (in millions) 2021 $ 2.1 2022 $ 2.0 2023 $ 1.9 2024 $ 1.7 2025 $ 1.6 We review our capitalized patent costs regularly to ensure that they include costs for patents and patent applications that have future value. When we identify patents and patent applications that we are not actively pursuing, we write off any associated costs. In 2020, 2019 and 2018, patent expenses were $4.1 million, $4.2 million and $2.6 million, respectively, and included non-cash charges related to the write-down of our patent costs to their estimated net realizable values of $1.9 million, $2.2 million and $0.8 million, respectively. |
Noncontrolling Interest in Akcea Therapeutics, Inc. | Noncontrolling Interest in Akcea Therapeutics, Inc. Since Akcea’s IPO in July 2017 and prior to the Akcea Acquisition in October 2020, the shares of Akcea’s common stock third parties owned represented an interest in Akcea’s equity that we did not control. During this period our ownership ranged from to . However, as we maintained overall control of Akcea through our voting interest, we reflected the assets, liabilities and results of operations of Akcea in our consolidated financial statements. Since Akcea’s IPO in July 2017 and through the closing of the Akcea Acquisition, we reflected the noncontrolling interest attributable to other owners of Akcea’s common stock on a separate line on our statement of operations and a separate line within stockholders’ equity in our consolidated balance sheet. In addition, through the closing of the Akcea Acquisition, we recorded a noncontrolling interest adjustment to account for the stock options Akcea granted, which if exercised, would have diluted our ownership in Akcea. This adjustment was a reclassification within stockholders’ equity from additional paid-in capital to noncontrolling interest in Akcea equal to the amount of stock-based compensation expense Akcea had recognized. Additionally, w |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments and receivables. We place our cash equivalents and short-term investments with reputable financial institutions. We primarily invest our excess cash in commercial paper and debt instruments of the U.S. Treasury, financial institutions, corporations, and U.S. government agencies with strong credit ratings and an investment grade rating at or above A-1, P-1 or F-1 by Moody’s, Standard & Poor’s, or S&P, or Fitch, respectively. We have established guidelines relative to diversification and maturities that maintain safety and liquidity. We periodically review and modify these guidelines to maximize trends in yields and interest rates without compromising safety and liquidity. |
Cash, Cash Equivalents and Investments | Cash, Cash Equivalents and Investments We consider all liquid investments with maturities of three months or less when we purchase them to be cash equivalents. Our short-term investments have initial maturities of greater than three months from date of purchase. We classify our short-term debt investments as “available-for-sale” and carry them at fair market value based upon prices on the last day of the fiscal period for identical or similar items. We record unrealized gains and losses on debt securities as a separate component of comprehensive income (loss) and include net realized gains and losses in gain (loss) on investments in our consolidated statement of operations. We use the specific identification method to determine the cost of securities sold. We also have equity investments of less than 20 percent ownership in publicly and privately held biotechnology companies that we received as part of a technology license or partner agreement. At December 31, 2020, we held equity investments in two publicly held companies, ProQR Therapeutics N.V., or ProQR, and Antisense Therapeutics Limited, or ATL. We also held equity investments in seven privately-held companies, Aro Biotherapeutics, Atlantic Pharmaceuticals Limited, Dynacure SAS, Empirico, Inc., Flamingo Therapeutics BV, Seventh Sense Biosystems and Suzhou-Ribo Life Science Co, Ltd. We are required to measure and record our equity investments at fair value and to recognize the changes in fair value in our consolidated statement of operations. We account for our equity investments in privately held companies at their cost minus impairments, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. For example, during the second and fourth quarters of 2020, we revalued our investments in privately held companies, Dynacure, Suzhou-Ribo and Aro Biotherapeutics because the companies sold additional equity securities that were similar to the equity we own. These observable price changes resulted in us recognizing a $ million gain on our investment in Dynacure, a $ million gain on our investment in Suzhou-Ribo and a $ million gain on our investment in Aro Biotherapeutics in our consolidated statement of operations during 2020 because the sales were at higher prices compared to our recorded value. |
Inventory Valuation | Inventory Valuation We reflect our inventory on our consolidated balance sheet at the lower of cost or net realizable value under the first-in, first-out method, or FIFO. We capitalize the costs of raw materials that we purchase for use in producing our medicines because until we use these raw materials, they have alternative future uses, which we refer to as clinical raw materials. We include in inventory raw material costs for medicines that we manufacture for our partners under contractual terms and that we use primarily in our clinical development activities and drug products. We can use each of our raw materials in multiple products and, as a result, each raw material has future economic value independent of the development status of any single medicine. For example, if one of our medicines failed, we could use the raw materials for that medicine to manufacture our other medicines. We expense these costs as R&D expenses when we begin to manufacture API for a particular medicine if the medicine has not been approved for marketing by a regulatory agency. We obtained the first regulatory approval for TEGSEDI in July 2018 and for WAYLIVRA in May 2019. At December 31, 2020, our physical inventory for TEGSEDI and WAYLIVRA included API that we produced prior to when we obtained regulatory approval. As such, this API has no cost basis as we had previously expensed the costs as R&D expenses. We review our inventory periodically and reduce the carrying value of items we consider to be slow moving or obsolete to their estimated net realizable value based on forecasted demand compared to quantities on hand. We consider several factors in estimating the net realizable value, including shelf life of our inventory, alternative uses for our medicines in development and historical write-offs. We recorded an insignificant Our inventory consisted of the following (in thousands): December 31, 2020 2019 Raw materials: Raw materials- clinical $ 9,206 $ 9,363 Raw materials- commercial 7,502 6,520 Total raw materials 16,708 15,883 Work in process 2,252 2,039 Finished goods 3,005 258 Total inventory $ 21,965 $ 18,180 |
Property, Plant and Equipment | Property, Plant and Equipment We carry our property, plant and equipment at cost and depreciate it on the straight-line method over its estimated useful life, which consists of the following (in thousands): Estimated Useful Lives December 31, (in years) 2020 2019 Computer software, laboratory, manufacturing and other equipment 3 to 10 $ 68,990 $ 60,965 Building, building improvements and building systems 15 to 40 137,879 119,830 Land improvements 20 8,391 2,853 Leasehold improvements 5 to 15 17,263 13,600 Furniture and fixtures 5 to 10 12,871 7,354 245,394 204,602 Less accumulated depreciation (87,379 ) (74,013 ) 158,015 130,589 Land 23,062 23,062 Total $ 181,077 $ 153,651 We depreciate our leasehold improvements using the shorter of the estimated useful life or remaining lease term. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments We have estimated the fair value of our financial instruments. The amounts reported for cash, accounts receivable, accounts payable and accrued expenses approximate the fair value because of their short maturities. We report our investment securities at their estimated fair value based on quoted market prices for identical or similar instruments. |
Leases | Leases We determine if an arrangement contains a lease at inception. We currently only have operating leases. We recognize a right-of-use operating lease asset and associated short- and long-term operating lease liability on our consolidated balance sheet for operating leases greater than one year. Our right-of-use assets represent our right to use an underlying asset for the lease term and our lease liabilities represent our obligation to make lease payments arising from the lease arrangement. We recognize our right-of-use operating lease assets and lease liabilities based on the present value of the future minimum lease payments we will pay over the lease term. As our current leases do not provide an interest rate implicit in the lease, we used our incremental borrowing rate, based on the information available on the date we adopted Topic 842 (January 2019), as of the lease inception date or at the lease option extension date in determining the present value of future payments. We recognize rent expense for our minimum lease payments on a straight-line basis over the expected term of our lease. We recognize period expenses, such as common area maintenance expenses, in the period we incur the expense. |
Long-Lived Assets | Long-Lived Assets We evaluate long-lived assets, which include property, plant and equipment and patent costs, for impairment on at least a quarterly basis and whenever events or changes in circumstances indicate that we may not be able to recover the carrying amount of such assets. We recorded charges of $1.9 million, $2.2 million and $0.8 million for the years ended December 31, 2020, 2019 and 2018, respectively, related to the write-down of patents. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. |
Stock-Based Compensation Expense | Stock-Based Compensation Expense We measure stock-based compensation expense for equity-classified awards, principally related to stock options, RSUs, and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense over the requisite service period in our consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP. On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The expected term of stock options granted represents the period of time that we expect them to be outstanding. We estimate the expected term of options granted based on historical exercise patterns. We recognize compensation expense for option awards and RSUs using the accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period. The fair value of RSUs is based on the market price of our common stock on the date of grant. The RSUs we have granted vest annually over a four-year period.

Accumulated Other Comprehensive Loss | Accumulated Other Comprehensive Loss Accumulated other comprehensive loss is comprised of unrealized gains and losses on investments, net of taxes and currency translation adjustments. The following table summarizes changes in accumulated other comprehensive loss for the years ended December 31, 2020 , 2019 and 2018 (in thousands): Year Ended December 31, 2020 2019 2018 Beginning balance accumulated other comprehensive loss $ (25,290 ) $ (32,016 ) $ (31,759 ) Unrealized gains (losses) on securities, net of tax (1) 3,729 6,633 (280 ) Currency translation adjustment 617 93 23 Adjustments to other comprehensive loss from purchase of noncontrolling interest of Akcea Therapeutics, Inc.

For the years ended December 31, 2019 and 2018, we had a tax benefit $1.4 million and $0.3 million included in other comprehensive loss respectively. |
Convertible Debt | Convertible Debt At issuance, we accounted for our convertible debt instruments, including our 0.125 percent senior convertible notes, or 0.125% Notes, and 1 percent senior convertible notes, or 1% Notes, that may be settled in cash upon conversion (including partial cash settlement) by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate on the date the notes were issued. In reviewing debt issuances, we were not able to identify any comparable companies that issued non-convertible debt instruments at the time of the issuance of the convertible notes. Therefore, we estimated the fair value of the liability component of our notes by using assumptions that market participants would use in pricing a debt instrument, including market interest rates, credit standing, yield curves and volatilities. We assigned a value to the debt component of our convertible notes equal to the estimated fair value of similar debt instruments without the conversion feature, which resulted in us recording our debt at a discount. We are amortizing our debt issuance costs and debt discount over the life of the convertible notes as additional non-cash interest expense utilizing the effective interest method. For additional information, see Note 3, Long-Term Obligations and Commitments The 1% Notes mature in November 2021. Therefore, as of December 31, 2020, we classified the liability component of the 1% Notes as a current liability on our consolidated balance sheet. In August 2020, the FASB issued guidance simplifying the accounting for convertible debt instruments. See the section titled “Impact of Recently Issued Accounting Standards” below for details. |
Call Spread | Call Spread In conjunction with the issuance of our 0.125% Notes, we entered into a call spread transaction, which was comprised of purchasing note hedges and selling warrants. We account for the note hedges and warrants as separate freestanding financial instruments and treat each instrument as a separate unit of accounting. We determined that the note hedges and warrants do not meet the definition of a liability using the guidance contained in ASC Topic 480, therefore we account for the note hedges and warrants using the Derivatives and Hedging – Contracts in Entity’s Own Equity accounting guidance contained in ASC Topic 815. We determined that the note hedges and warrants meet the definition of a derivative, are indexed to our stock and meet the criteria to be classified in shareholders’ equity. We recorded the aggregate amount paid for the note hedges and the aggregate amount received for the warrants as additional paid-in capital in our consolidated balance sheet. We reassess our ability to continue to classify the note hedges and warrants in shareholders’ equity at each reporting period. |
Segment Information | Segment Information Through 2020, we had two operating segments, our Ionis Core segment and Akcea Therapeutics. Akcea was focused on developing and commercializing medicines to treat patients with serious and rare diseases. We have provided segment financial information and results for our Ionis Core segment and our Akcea Therapeutics segment based on the segregation of revenues and expenses that our chief decision maker reviewed to assess operating performance and to make operating decisions through 2020. We allocated a portion of Ionis’ development, R&D support and general and administrative expenses to Akcea for work Ionis performed on behalf of Akcea and we billed Akcea for these expenses. |
Fair Value Measurements | Fair Value Measurements We use a three-tier fair value hierarchy to prioritize the inputs used in our fair value measurements. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets, which includes our money market funds and treasury securities classified as available-for-sale securities and our investment in equity securities in publicly held biotechnology companies; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable, which includes our fixed income securities and commercial paper classified as available-for-sale securities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring us to develop our own assumptions. We classify most of our securities as Level 2. We obtain the fair value of our Level 2 investments from our custodian bank or from a professional pricing service. We validate the fair value of our Level 2 investments by understanding the pricing model used by the custodian banks or professional pricing service provider and comparing that fair value to the fair value based on observable market prices. The following tables present the major security types we held at December 31, 2020 and 2019 that we regularly measure and carry at fair value subject to trading restrictions until the fourth quarter of 2020, as a result we At December 31, 2020 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Cash equivalents (1) $ 221,125 $ 221,125 $ — Corporate debt securities (2) 846,315 — 846,315 Debt securities issued by U.S. government agencies (4) 174,861 — 174,861 Debt securities issued by the U.S. Treasury (3) 358,497 358,497 — Debt securities issued by states of the U.S. and political subdivisions of the states (4) 136,309 — 136,309 Other municipal debt securities (4) 6,225 — 6,225 Investment in ProQR Therapeutics N.V.

Income Taxes | Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. We record a valuation allowance when necessary to reduce our net deferred tax assets to the amount expected to be realized. We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50 percent likely to be realized upon ultimate settlement. We are required to use significant judgment in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe our reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historical income tax provisions and accruals. We adjust these reserves for changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences may impact the provision for income taxes in the period in which such determination is made. We are also required to use significant judgment in determining any valuation allowance recorded against our deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including scheduled reversal of deferred tax liabilities, past operating results, the feasibility of tax planning strategies and estimates of future taxable income. We base our estimates of future taxable income on assumptions that are consistent with our plans. The assumptions we use represent our best estimates and involve inherent uncertainties and the application of our judgment. Should actual amounts differ from our estimates, the amount of our tax expense and liabilities we recognize could be materially impacted. We record a valuation allowance to reduce the balance of our net deferred tax assets to the amount we believe is more-likely-than-not to be realized. We do not provide for a U.S. income tax liability and foreign withholding taxes on undistributed foreign earnings of our foreign subsidiaries. |
Impact of Recently Issued Accounting Standards | Impact of Recently Issued Accounting Standards In June 2016, the FASB issued guidance that changes the measurement of credit losses for most financial assets and certain other instruments. If we have credit losses, this updated guidance requires us to record allowances for these instruments under a new expected credit loss model. This model requires us to estimate the expected credit loss of an instrument over its lifetime, which represents the portion of the amortized cost basis we do not expect to collect. The new guidance requires us to remeasure our allowance in each reporting period we have credit losses. We adopted this new guidance on January 1, 2020. This guidance did not have an impact on our consolidated financial statements. In August 2018, the FASB issued clarifying guidance on how to account for implementation costs related to cloud-servicing arrangements. The guidance states that if these fees qualify to be capitalized and amortized over the service period, they need to be expensed in the same line item as the service expense and recognized in the same balance sheet category. The update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We adopted this guidance on January 1, 2020 on a prospective basis. This guidance did not have an impact on our consolidated financial statements. In November 2018, the FASB issued clarifying guidance of the interaction between the collaboration accounting guidance and the new revenue recognition guidance we adopted on January 1, 2018 (Topic 606). Below is the clarifying guidance and how we implemented it (in italics): 1) When a participant is considered a customer in a collaborative arrangement, all of the associated accounting under Topic 606 should be applied. ● We are applying all of the associated accounting under Topic 606 when we determine a participant in a collaborative arrangement is a customer. 2) Adds “unit of account” concept to collaboration accounting guidance to align with Topic 606. The “unit of account” concept is used to determine if revenue is recognized or if a contra expense is recognized from consideration received under a collaboration. ● We use the “unit of account” concept when we receive consideration under a collaborative arrangement to determine when we recognize revenue or a contra expense. 3) The clarifying guidance precludes us from recognizing revenue under Topic 606 when we determine a transaction with a collaborative partner is not a customer and is not directly related to the sales to third parties. ● When we conclude a collaboration partner is not a customer and is not directly related to the sales to third parties, we do not recognize revenue for the transaction. We adopted this new guidance on January 1, 2020. This guidance did not have any impact on our consolidated financial statements. In August 2020, the FASB issued guidance , amends the guidance on derivative scope exceptions for contracts in an entity’s own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. Under our current outstanding convertible debt arrangements, we anticipate the following impacts: 1) We will no longer separate our existing convertible debt into liability and equity components. Therefore, we will no longer recognize a debt discount for the value of the conversion option, instead we will record the face value of the convertible debt as a liability on our consolidated balance sheet; 2) We will record cash interest expense plus amortization of debt issuance costs to interest expense. Since we will not recognize a debt discount, we will no longer record the amortization of a debt discount to interest expense; and 3) We do not expect our EPS calculation to not change under this update. We plan to continue to use the if-converted method to calculate diluted earnings per share. We plan to adopt this guidance in the first quarter of 2021 under the full retrospective approach, meaning we will apply the guidance to all periods presented beginning in the first quarter of 2021. |

As a result, we recorded our convertible notes at a discount, which we are amortizing as additional non-cash interest expense over the expected life of the respective debt. We determined our nonconvertible debt borrowing rate using a combination of the present value of the debt’s cash flows and a Black-Scholes valuation model. The following table summarizes the nonconvertible borrowing rate, effective interest rate and amortization period of our debt discount for our convertible notes: 1% Notes 0.125% Nonconvertible debt borrowing rate 7.4 percent 4.4 percent Effective interest rate (1) 7.5 percent 4.9 percent Amortization period of debt discount 7 years 5 years ________________ (1) For our 1% Notes, our effective interest rate represents our effective interest rate after our December 2019 debt exchange. |

[1] | As discussed in Note 1, Organization and Significant Accounting Policies, we compute basic net income (loss) per share by dividing the total net income (loss) attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. Our basic net income (loss) per share calculation for each of the fourth quarters in 2020 and 2019 considered our net income (loss) for Ionis on a stand-alone basis plus our share of Akcea’s net loss for the period. To calculate the portion of Akcea’s net loss attributable to our ownership, we multiplied Akcea’s loss per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net income (loss) available to Ionis common stockholders for the calculation of net income (loss) per share is different than net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders in the consolidated statements of operations. | ||||||||
[2] | We compute net income (loss) per share independently for each quarter during the year. | ||||||||
[3] | We had net income available to Ionis common stockholders for the fourth quarter of 2019. As a result, we computed diluted net income per share using the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period |

Weighted average shares owned in Akcea (in shares) | 77,095 | 71,342 | |||||||
[1] | As discussed in Note 1, Organization and Significant Accounting Policies, we compute basic net income (loss) per share by dividing the total net income (loss) attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. Our basic net income (loss) per share calculation for each of the fourth quarters in 2020 and 2019 considered our net income (loss) for Ionis on a stand-alone basis plus our share of Akcea’s net loss for the period. To calculate the portion of Akcea’s net loss attributable to our ownership, we multiplied Akcea’s loss per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net income (loss) available to Ionis common stockholders for the calculation of net income (loss) per share is different than net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders in the consolidated statements of operations. | ||||||||
[2] | We compute net income (loss) per share independently for each quarter during the year. | ||||||||
[3] | We had net income available to Ionis common stockholders for the fourth quarter of 2019. As a result, we computed diluted net income per share using the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period |
