| 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 condensed 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: TEGSEDI and WAYLIVRA revenue, net In the United States, or U.S., through the first quarter of 2021, we sold TEGSEDI through an exclusive distribution agreement with a third-party logistics company, or 3PL, that took title to TEGSEDI. The 3PL was our sole customer in the U.S. The 3PL then distributed TEGSEDI to a specialty pharmacy and a specialty distributor, which we collectively refer to as wholesalers, who then distributed TEGSEDI to health care providers and patients. In Europe, through 2020, we sold TEGSEDI and WAYLIVRA to hospitals and pharmacies, which were our customers, using 3PLs as distributors. In January 2021, we began commercializing TEGSEDI and WAYLIVRA in Europe through a distribution agreement with Swedish Orphan Biovitrum AB, or Sobi. In April 2021, we expanded our distribution agreement with Sobi to also include commercializing TEGSEDI in North America. Under our agreements, we are responsible for supplying finished goods inventory to Sobi and Sobi is responsible for selling each medicine to the end customer. As a result of these agreements, we earn a distribution fee on net sales from Sobi for each medicine. Under our collaboration agreement with PTC, PTC is responsible for 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. See Note 5, Collaborative Arrangements and Licensing Agreements , for collaborations with substantive changes that occurred in 2021. Additionally, see 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 a $20 million milestone payment from AstraZeneca when AstraZeneca initiated a Phase 2b study for ION449, our medicine in development targeting PCSK9 to lower LDL-cholesterol. We did not consider the milestone payment probable until AstraZeneca achieved the milestone event because advancing ION449 was contingent on AstraZeneca initiating a Phase 2b 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 one 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 third 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 one of two 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. 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: TEGSEDI and WAYLIVRA revenue, net Prior to our distribution agreement with Sobi, we recognized TEGSEDI and WAYLIVRA commercial revenue in the period when our customer obtained control of our products, which occurred at a point in time upon transfer of title to the customer. We classified payments to customers or other parties in the distribution channel for services that were distinct and priced at fair value as selling, general and administrative, or SG&A, expenses in our condensed consolidated statements of operations. We classified payments to customers or other parties in the distribution channel that did not meet those criteria as a reduction of revenue, as discussed further below. We excluded from revenues taxes collected from customers relating to TEGSEDI and WAYLIVRA commercial revenue and remitted these amounts to governmental authorities. Under our distribution agreement with Sobi we concluded that our performance obligation is to supply finished goods inventory to Sobi. This performance obligation is a series of distinct activities that are substantially the same because we transfer title using the same criteria each time we ship inventory to Sobi. Therefore, we recognize as revenue the price Sobi pays us for the inventory when we deliver the finished goods inventory to Sobi. We also recognize distribution fee revenue based on Sobi’s net sales of TEGSEDI and WAYLIVRA. Additionally, Sobi does not generally have a right of return. Reserves for TEGSEDI and WAYLIVRA commercial revenue Prior to our distribution agreement with Sobi, w Organization and Significant Accounting Policies Under our distribution agreement with Sobi, Sobi is financially responsible for any applicable reserves. 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 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 $7.5 million milestone payment from Biogen when we advanced a target under our 2018 strategic collaboration. 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 $30 million license fee from AstraZeneca when AstraZeneca licensed ION455, 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 sold 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 $ 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 As of March 31, 2021, approximately 46.8 percent of our contracts receivables were from three significant customers. As of December 31, 2020, approximately 99.5 percent of our contracts receivables were from two significant customers. |
| 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 condensed 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 condensed consolidated balance sheet. |
| Cost of Sales | Cost of Sales Our cost of sales 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 sales. |
| 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 condensed 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 March 31, 2021, 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 condensed 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 three 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 $6.3 million gain on our investment in Dynacure, a $3.0 million gain on our investment in Suzhou-Ribo and a $5.5 million gain on our investment in Aro Biotherapeutics in our condensed 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 condensed 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 March 31, 2021, 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 amount of inventory write-offs for the . Our inventory consisted of the following (in thousands):
March 31, 2021 December 31, 2020
Raw materials:
Raw materials- clinical $ 10,695 $ 9,206
Raw materials- commercial 7,502 7,502
Total raw materials 18,197 16,708
Work in process 2,096 2,252
Finished goods 1,906 3,005
Total inventory $ 22,199 $ 21,965 |
| 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 condensed 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. We determine the lease term at the inception of each lease, and in certain cases our lease term could include renewal options if we concluded we were reasonably certain that we will exercise the renewal option. When we exercise a lease option that was not previously included in the initial lease term, we reassess our right-of-use asset and lease liabilities for the new 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. |
| 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 condensed consolidated balance sheet and we expense them as the services are provided. |
| 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. . |
| 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 we expect to realize. 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. We assessed our valuation allowance requirements and recorded a valuation allowance 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. We based our determination 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 we expect this 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. We also expect 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 continue to maintain a valuation allowance against all our consolidated U.S. federal and state net deferred tax assets. |
| 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. |
| Use of Estimates | Use of Estimates We prepare our condensed consolidated financial statements in conformity with accounting principles generally accepted in the |
| Basic and Diluted Net Loss per Share | Basic and Diluted Net Loss Per Share Basic net loss per share In the first quarter of 2021, we computed basic net loss per share by dividing our net loss by our weighted-average number of common shares outstanding during the period. For the first quarter of 2021, we did not have to consider Akcea results separately in our calculation because we owned 100 percent of Akcea for the entire period. Our basic net loss per share for the three months ended March 31, 2021 was $0.64. In the first quarter of 2020, prior to the Akcea Acquisition, we calculated our net loss for Ionis on a stand-alone basis plus our share of Akcea’s net loss for the period to determine our total net loss attributable to our common stockholders. To calculate the portion of Akcea’s net loss attributable to our ownership, we multiplied Akcea’s net loss per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net loss available to Ionis common stockholders for the calculation of net loss per share is different than our net loss attributable to Ionis Pharmaceuticals, Inc. common stockholders in the condensed consolidated statements of operations. Our basic net loss per share for the three months ended March 31, 2020, was calculated as follows (in thousands, except per share amounts):
Three months ended March 31, 2020 Weighted Average Shares Owned in Akcea Akcea’s Net Loss Per Share Basic Net Loss Per Share Calculation (as revised*)
Ionis’ portion of Akcea’s net loss 77,095 $ (0.42 ) $ (32,674 )
Akcea’s net loss attributable to our ownership $ (32,674 )
Ionis’ stand-alone net loss (7,032 )
Net loss available to Ionis common stockholders $ (39,706 )
Weighted average shares outstanding 139,429
Basic net loss per share $ (0.28 )
* We revised our 2020 amounts to reflect the simplified convertible instruments accounting guidance, which we adopted retrospectively. Refer to Note 2, Significant Accounting Policies Diluted net loss per share For the three months ended March 31, 2021 and 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;
● Note hedges related to the 0.125 percent convertible senior notes;
● 1 percent convertible senior notes;
● Dilutive stock options;
● Unvested restricted stock units, or RSUs;
● Unvested performance restricted stock units, or PRSUs; and
● Employee Stock Purchase Plan, or ESPP. Additionally as of March 31, 2021, we had warrants related to our 0.125 percent convertible senior notes outstanding. We will include the shares issuable under these 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. |
| Convertible Debt | Convertible Debt Adoption of ASU 2020-06 In August 2020, the FASB issued ASU 2020-06, which simplifies , 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. We adopted ASU 2020-06 on January 1, 2021 under the full retrospective approach, which required us to revise our prior period financial statements. This guidance impacted our accounting for outstanding convertible debt. As of March 31, 2021, we had outstanding convertible notes, our senior convertible notes, or Notes, which mature in December 2024, and our senior convertible notes, or Notes, which mature in November 2021. The updated guidance eliminates the cash conversion accounting model we previously followed in Accounting Standard Codification, or ASC, 470-20, which required us to separate each of our convertible debt instruments at issuance into two units of accounting, a liability component, based on our nonconvertible debt borrowing rate at issuance, and an equity component. Under ASU 2020-06, we now account for each of our convertible debt instruments as a single unit of accounting, a liability, because we concluded that the conversion features do not require bifurcation as a derivative under ASC 815-15 and our convertible debt instruments were not issued at a substantial premium. Since we adopted ASU 2020-06 using the full retrospective approach, we were required to apply the guidance to all convertible debt instruments we had outstanding as of January 1, 2019. We recomputed the basis of each convertible debt instrument as if we accounted for each as a single unit of accounting at issuance. This update included recalculating the amortization of debt issuance costs using an updated effective interest rate. As a result of adopting ASU 2020-06, we recorded a cumulative adjustment to decrease our additional paid in capital and our accumulated deficit at January 1, 2019. We have updated these financial statements to reflect the cumulative adjustment for the periods presented. We have labeled our prior period financial statements “as revised” to indicate the change required under the new accounting guidance. Below is a summary of the change in our balance sheet at December 31, 2020 and statement of operations from our first quarter 2020 under the ASC 470-20 legacy guidance compared to the new ASU 2020-06 guidance we adopted: The following table summarizes the adjustments we made to the condensed consolidated balance sheet we originally reported at December 31, 2020 to adopt ASU 2020-06 (in thousands):
December 31, 2020
As Previously Reported ASU 2020-06 Adjustment As Revised
1 percent convertible senior notes $ 293,161 $ 15,648 $ 308,809
0.125 percent convertible senior notes $ 455,719 $ 84,417 $ 540,136
Additional paid-in-capital $ 2,113,646 $ (218,127 ) $ 1,895,519
Accumulated deficit $ (1,249,368 ) $ 118,062 $ (1,131,306 ) Under ASU 2020-06, our revised ending balances for our 1% Notes and 0.125% Notes as of December 31, 2020 represent the principal balance of each convertible debt instrument less debt issuance costs. Additionally, because we have deferred tax assets related to our convertible debt instruments, we also adjusted these amounts as part of our adoption of ASU 2020-06. However, because we have a full valuation allowance on our deferred tax assets, there was no impact to our condensed consolidated balance sheet related to our deferred tax assets. The following table summarizes the adjustments we made to the condensed consolidated statement of operations we originally reported at March 31, 2020 to adopt ASU 2020-06 (in thousands):
Three Months Ended March 31, 2020
As Previously Reported ASU 2020-06 Adjustment As Revised
Interest expense $ (10,990 ) $ 8,783 $ (2,207 )
Loss before income tax benefit $ (61,737 ) $ 8,783 $ (52,954 )
Income tax benefit $ 3,257 $ (185 ) $ 3,072
Net loss $ (58,480 ) $ 8,598 $ (49,882 )
Net loss attributable to Ionis Pharmaceuticals, Inc. common stockholders $ (48,226 ) $ 8,598 $ (39,628 )
Basic and diluted net loss per share $ (0.35 ) $ 0.07 $ (0.28 ) Under ASU 2020-06, our revised interest expense is lower as we are no longer recording non-cash interest expense related to a debt discount. This decrease was partially offset by the increase in interest expense related to the amortization of debt issuance costs because we no longer allocate a portion of our debt issuance costs to stockholders’ equity at issuance. Instead, the entire debt issuance costs were recorded as a contra-liability on our condensed consolidated balance sheet at issuance and we are amortizing them over the contractual term using an updated effective interest rate. Our updated effective interest rates for our 1% Notes and 0.125% Notes were 1.4 percent and 0.5 percent, respectively. The following tables summarize the adjustments we made to our condensed consolidated statements of stockholders’ equity we originally reported at December 31, 2020 and 2019 to adopt ASU 2020-06 (in thousands):
December 31, 2020
As Previously Reported ASU 2020-06 Adjustment As Revised
Additional paid-in-capital $ 2,113,646 $ (218,127 ) $ 1,895,519
Accumulated deficit $ (1,249,368 ) $ 118,062 $ (1,131,306 )
Total stockholders' equity $ 843,347 $ (100,065 ) $ 743,282
December 31, 2019
As Previously Reported ASU 2020-06 Adjustment As Revised
Additional paid-in-capital $ 2,203,778 $ (218,128 ) $ 1,985,650
Accumulated deficit $ (707,534 ) $ 111,039 $ (596,495 )
Total stockholders' equity $ 1,684,547 $ (107,089 ) $ 1,577,458 |
| Call Spread | Call Spread In conjunction with the issuance of our 0.125% Notes in December 2019, 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 condensed 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 In 2021, we began operating as a single segment, Ionis operations, because our chief decision maker reviews operating results on an aggregate basis and manages our operations as a single operating segment. Previously, we had operated as two operating segments, Ionis Core and Akcea Therapeutics. In October 2020, we acquired the remaining common stock of Akcea that we did not own and fully integrated Akcea’s operations into ours as of January 1, 2021. |
| 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 condensed 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. We recognize compensation expense for stock options granted, RSUs, PRSUs 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. 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. As a result, all employees are now under an Ionis stock plan and subject to the same Black-Scholes assumptions. During the three months ended March 31, 2021 and 2020, we did not grant any stock options or RSUs to our Board of Directors. For the three months ended March 31, 2021 and 2020, we used the following weighted-average assumptions in our Black-Scholes calculations: Employee Stock Options:
Three Months Ended March 31,
2021 2020
Risk-free interest rate 0.5 % 1.6 %
Dividend yield 0.0 % 0.0 %
Volatility 55.1 % 58.9 %
Expected life 4.9 years 4.7 years ESPP:
Three Months Ended March 31,
2021 2020
Risk-free interest rate 0.1 % 1.1 %
Dividend yield 0.0 % 0.0 %
Volatility 39.1 % 47.2 %
Expected life 6 months 6 months RSU’s: 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 to employees vest annually over a four-year period. The RSUs we granted to our board of directors prior to June 2020 vest annually over a four-year period. RSUs granted after June 2020 to our board of directors fully vest after one year. The weighted-average grant date fair value of RSUs granted to employees for the three months ended March 31, 2021 was $62.02 per share. PRSU’s: Beginning in 2020, we added performance-based restricted stock units, or PRSU, awards to the compensation for our Chief Executive Officer, Dr. Brett Monia. Under the terms of the grants, one third We determined the fair value of Dr. Monia’s PRSUs using a Monte Carlo model because the performance target is based on our relative TSR, which represents a market condition. We are recognizing the grant date fair value of these awards as stock-based compensation expense using the accelerated multiple-option approach over the vesting period. The weighted-average grant date fair value of PRSUs granted to Dr. Monia for the three months ended March 31, 2021 was $77.17 per share. The following table summarizes stock-based compensation expense for the three months ended March 31, 2021 and 2020 (in thousands).
Three Months Ended March 31,
2021 2020
Cost of sales $ 182 $ 237
Research, development and patent expense 25,899 25,556
Selling, general and administrative expense 11,780 14,997
Total $ 37,861 $ 40,790 As of March 31, 2021, total unrecognized estimated non-cash stock-based compensation expense related to non-vested stock options, RSUs and PRSUs was $101.8 million, $109.6 million and $3.8 million, respectively. Our actual expenses may differ from these estimates because we will adjust our unrecognized non-cash stock-based compensation expense for future forfeitures. We expect to recognize the cost of non-cash stock-based compensation expense related to our non-vested stock options, RSUs and PRSUs over a weighted average amortization period of 1.4 years, 1.8 years and 1.7 years, respectively. |
| Impact of Recently Issued Accounting Standards | Impact of Recently Issued Accounting Standards As disclosed in the “Convertible Debt” policy above within this footnote, we adopted the simplified accounting for convertible debt instrument guidance (ASU 2020-06) on January 1, 2021. Refer to the section above for the impact of adoption. We do not expect any other recently issued accounting standards to have a material impact to our financial results. |
