Business Overview

La Jolla Pharmaceutical Company is dedicated to the commercialization of innovative therapies that improve outcomes in patients suffering from life-threatening diseases. GIAPREZA® (angiotensin II) injection is approved by the U.S. Food and Drug Administration ("FDA") as a vasoconstrictor indicated to increase blood pressure in adults with septic or other distributive shock. XERAVA® (eravacycline) for injection is approved by the FDA as a tetracycline class antibacterial indicated for the treatment of complicated intra-abdominal infections ("cIAI") in patients 18 years of age and older.

On July 28, 2020, La Jolla completed its acquisition of Tetraphase Pharmaceuticals, Inc. and its subsidiaries ("Tetraphase"), a biopharmaceutical company focused on commercializing XERAVA, for $43 million in upfront cash plus potential future cash payments of up to $16 million. La Jolla's consolidated financial results exclude Tetraphase's financial results prior to the acquisition closing date of July 28, 2020.

In January 2021, La Jolla and certain of its wholly owned subsidiaries entered into an exclusive license agreement with PAION AG to commercialize GIAPREZA and XERAVA in the European Economic Area, the United Kingdom and Switzerland. Pursuant to the agreement: (i) the Company has received an upfront cash payment of $22.5 million, less a 15% refundable withholding tax; and (ii) the Company is entitled to receive potential commercial milestone payments of up to $109.5 million and royalties on net sales of GIAPREZA and XERAVA.

On November 2, 2021, La Jolla consummated the change of its corporate domicile from California to Delaware, as described in more detail in La Jolla's Definitive Proxy Statement on Schedule 14A filed with the U.S. Securities and Exchange Commission (the "SEC") on June 4, 2021.

La Jolla acquired Tetraphase, which commercialized XERAVA, on July 28, 2020. La Jolla's consolidated financial results for the year ended December 31, 2020 exclude the financial results of Tetraphase prior to July 28, 2020.

Net Product Sales

Net product sales consist of revenue recognized from sales of GIAPREZA and XERAVA to hospitals and other healthcare organizations in the U.S., generally through a network of specialty and wholesale distributors. These specialty and wholesale distributors are considered our customers for accounting purposes.

La Jolla's net product sales were $12.1 million and $43.5 million for the three and twelve months ended December 31, 2021, respectively, compared to $11.0 million and $33.4 million, respectively, for the same periods in 2020. La Jolla acquired Tetraphase, which commercialized XERAVA, on July 28, 2020. Net product sales for the year ended December 31, 2020 exclude XERAVA for the period prior to July 28, 2020.

GIAPREZA U.S. net sales were $9.2 million and $33.4 million for the three and twelve months ended December 31, 2021, respectively, compared to $8.7 million and $29.3 million, respectively, for the same periods in 2020.

XERAVA U.S. net sales were $2.9 million and $10.1 million for the three and twelve months ended December 31, 2021, respectively, compared to $2.3 and $4.2 million, respectively, for the same periods in 2020. XERAVA U.S. net sales were $8.2 million for the year ended December 31, 2020, including the period prior to the acquisition of Tetraphase.

La Jolla's net product sales increased during the three and twelve months ended December 31, 2021, compared to the same periods in 2020 due to an increase in the number of vials sold to our customers.

License and Other Revenue

License and other revenue consists of revenue from out-license agreements with counterparties to develop and/or commercialize our products in territories outside of the U.S. in exchange for: (i) nonrefundable, upfront license fees; (ii) development, regulatory or commercial milestone payments; and/or (iii) sales-based royalties. License and other revenue also consists of revenue from commercial supply agreements with our out-licensees to supply a minimum quantity of our products in territories outside the U.S. in exchange for: (i) nonrefundable, upfront fees; and/or (ii) the reimbursement of manufacturing costs, plus a margin in certain cases.

La Jolla's license and other revenue was $32.2 million for the year ended December 31, 2021, which consists of: (i) a $22.5 million upfront cash payment in connection with the PAION License; (ii) $5.0 million for the transfer of certain XERAVA-related manufacturing know-how to Everest in connection with the Everest commercial supply agreement; (iii) a $3.0 million regulatory milestone cash payment in connection with the Everest License; and (iv) $1.7 million for the reimbursement of manufacturing costs in connection with commercial supply agreements with our out-licensees. La Jolla did not record license and other revenue during the year ended December 31, 2020.

Cost of Product Sales

Cost of product sales consists primarily of expense associated with: (i) manufacturing; (ii) royalties payable to George Washington University, Harvard University and Paratek Pharmaceuticals, Inc.; (iii) the inventory fair value step-up adjustment recorded in connection with the acquisition of Tetraphase; and (iv) shipping and distribution.

La Jolla's cost of product sales was $9.0 million for the year ended December 31, 2021, compared to $7.8 million, for the same period in 2020. Cost of product sales for the year ended December 31, 2020 exclude XERAVA prior to July 28, 2020. For the year ended December 31, 2021, cost of product sales includes $0.9 million of the inventory fair value step-up adjustment recorded in connection with the acquisition of Tetraphase, compared to $2.5 million for the same period in 2020.

Cost of License and Other Revenue

Cost of license and other revenue consists of amounts due under in-license agreements and commercial supply agreements in connection with license and other revenue from commercially approved product. Cost of license and other revenue recognized in connection with product that is not commercially approved is recorded as research and development expense.

La Jolla's cost of license and other revenue was $4.5 million for the year ended December 31, 2021, which consists of: (i) $3.6 million for amounts due under the George Washington University and Harvard University license agreements in connection with the upfront cash payment received from the PAION License; and (ii) $0.9 million for manufacturing costs in connection with commercial supply agreements with our out-licensees.

Selling, General and Administrative Expense

Selling, general and administrative expense consists of non-personnel and personnel expenses. Non-personnel-related expense includes expense related to: (i) sales and marketing costs such as speaker programs, advertising and promotion; (ii) professional fees for legal, patent, consulting, surveillance, regulatory filings and accounting; and (iii) amortization of intangible assets, information technology and facilities. Personnel-related expense includes expense related to salaries, benefits and share-based compensation for personnel engaged in sales, finance and administrative functions. We expect our selling, general and administrative expense to increase modestly in 2022 to support growing net product sales of both GIAPREZA and XERAVA.



The following table summarizes these expenses for each of the periods below (in
thousands):

                                                                Year Ended

Other                                                  3,610        2,861          749
Total non-personnel expense                           14,890       15,127         (237 )
Personnel expense:
Salaries, bonuses and benefits                        16,720       16,298          422

Total selling, general and administrative expense $ 35,386 $ 38,428 $ (3,042 )

During the year ended December 31, 2021, total selling, general and administrative non-personnel expense decreased compared to the same period in 2020 primarily as a result of: (i) decreases in facility-related expenses as a result of the termination of our lease for office and laboratory space in San Diego, California effective August 31, 2020; and (ii) decreases in professional fee-related expenses; partially offset by increases in expenses resulting from the inclusion of Tetraphase-related costs, which are excluded from La Jolla's financial results for the year ended December 31, 2020 prior to July 28, 2020. During the year ended December 31, 2020, La Jolla incurred acquisition-related expenses of $0.9 million.

During the year ended December 31, 2021, total selling, general and administrative personnel expense decreased compared to the same period in 2020 primarily as a result of one-time charges in 2020 resulting from: (i) a reduction of headcount from a Company-wide realignment in May 2020; and (ii) a reduction of headcount combining La Jolla and Tetraphase personnel in July 2020; partially offset by an increase in headcount and the average cost per employee.



                                       41

--------------------------------------------------------------------------------

Research and Development Expense

Research and development expense consists of non-personnel and personnel expenses. Non-personnel-related expense includes expense related to: (i) manufacturing development; (ii) amounts due under in-license agreements for drug product that is not commercially approved; (iii) facilities and information technology; and (iv) conducting clinical studies. Personnel-related expense includes expense related to salaries, benefits and share-based compensation for personnel engaged in research and development functions. We expect our research and development expense to decrease significantly.



The following table summarizes these expenses for each of the periods below (in
thousands):

                                                           Year Ended

Total research and development expense $ 5,014 $ 23,010 $ (17,996 )

During the year ended December 31, 2021, total research and development non-personnel expense decreased compared to the same period in 2020 primarily as a result of decreases in: (i) program-related expenses as we de-prioritized our product candidates and focused on the commercialization of GIAPREZA and XERAVA; (ii) manufacturing development-related expenses for GIAPREZA; and (iii) facility-related expenses primarily as a result of the termination of our lease for office and laboratory space in San Diego, California effective August 31, 2020.

During the year ended December 31, 2021, total research and development personnel expense, including share-based compensation expense, decreased compared to the same period in 2020 as a result of: (i) reduced headcount; and (ii) one-time charges in 2020 resulting from: (1) a reduction of headcount from a Company-wide realignment in May 2020; and (2) a reduction of headcount combining La Jolla and Tetraphase personnel in July 2020.

Research and development expense for the year ended December 31, 2020 excludes Tetraphase-related costs prior to July 28, 2020.



                                       42

--------------------------------------------------------------------------------

Other (Expense) Income, Net

Other (expense) income, net consists primarily of the following: (i) interest expense accrued for our deferred royalty obligation; (ii) income from distributions received in connection with our non-voting profits interest in a related party; (iii) gains and losses from changes in the fair value of contingent value rights ("CVRs"); (iv) interest income generated from cash held in savings accounts; and (v) gains and losses associated with the disposal of certain property and equipment.

During the year ended December 31, 2021, other (expense) income, net was $(2.1) million, compared to $(3.6) million for the same period in 2020. This $1.5 million decrease in other (expense) income, net was due to: (i) a $1.3 million increase in the receipt of distributions in connection with the Company's non-voting profits interest in a related party; and (ii) a $0.8 million decrease in loss on short-term investments; partially offset by: (i) a $0.4 million increase in interest expense for our deferred royalty obligation; and (ii) a $0.2 million decrease in interest income generated from cash held in savings accounts.

Liquidity and Capital Resources

As of December 31, 2021 and 2020, La Jolla had cash and cash equivalents of $46.7 million and $21.2 million, respectively. Based on our current operating plans and projections, we believe that our existing cash and cash equivalents will be sufficient to fund operations for at least one year from the date this Annual Report on Form 10-K is filed with the SEC. The Company expects to fund future operations with existing cash or cash generated from operations.

La Jolla's net cash provided by (used for) operating activities for the three and twelve months ended December 31, 2021 was $3.1 million and $28.2 million, respectively, compared to $(7.2) million and $(37.6) million, respectively, for the same periods in 2020.

La Jolla's net cash provided by (used for) operating activities for the three and twelve months ended December 31, 2021, excluding upfront net receipts in connection with out-license agreements and commercial supply agreements, payments related to reductions in headcount, and transaction costs associated with the Tetraphase acquisition, was $3.1 million and $4.6 million, respectively, compared to $(5.6) million and $(27.2) million, respectively, for the same periods in 2020. The exclusions above are comprised of the following:


   •  Upfront net receipts in connection with out-license agreements were zero and
      $18.4 million for the three and twelve months ended December 31, 2021,
      respectively, and zero for the same periods in 2020.


   •  Upfront net receipts in connection with commercial supply agreements were
      zero and $6.8 million for the three and twelve months ended December 31,
      2021, respectively, and zero for the same periods in 2020.


   •  Payments related to reductions in headcount were zero and $1.6 million for
      the three and twelve months ended December 31, 2021, respectively, and $1.6
      million and $9.5 million, respectively, for the same periods in 2020.


   •  Payments related to transaction costs associated with the Tetraphase
      acquisition were zero for the three and twelve months ended December 31,
      2021, and zero and $0.9 million, respectively, for the same periods in 2020.

The amount and timing of additional future funding needs, if any, will depend on many factors, including the success of our commercialization efforts for GIAPREZA and XERAVA and our ability to control expenses. If necessary, we intend to raise additional capital through equity or debt financings. We can provide no assurance that additional financing will be available to us on favorable terms, or at all.

Contractual Obligations

HealthCare Royalty Partners Royalty Agreement

In May 2018, we closed a $125.0 million royalty financing agreement (the "Royalty Agreement") with HealthCare Royalty Partners ("HCR"). Under the terms of the Royalty Agreement, we received $125.0 million in exchange for tiered royalty payments on worldwide net sales of GIAPREZA. HCR is entitled to receive quarterly royalties on worldwide net sales of GIAPREZA beginning April 1, 2018. Quarterly payments to HCR under the Royalty Agreement start at a maximum royalty rate, with step-downs based on the achievement of annual net product sales thresholds. Through December 31, 2021, the maximum royalty rate was 10%. Starting January 1, 2022, the maximum royalty rate increased by 4%, and starting January 1, 2024, the maximum royalty rate may increase by an additional 4% if an agreed-upon, cumulative net product sales threshold has not been met. The Royalty Agreement is subject to maximum aggregate royalty payments to HCR of $225.0 million. The Royalty Agreement expires upon the first to occur of January 1, 2031 or when the maximum aggregate royalty payments have been made. The Royalty Agreement was entered into by our wholly owned subsidiary, La Jolla Pharma, LLC, and HCR has no recourse under the Royalty Agreement against La Jolla Pharmaceutical Company or any assets other than GIAPREZA.

Out-license Agreements

PAION AG

In January 2021, La Jolla Pharmaceutical Company and certain of its wholly owned subsidiaries, including La Jolla Pharma, LLC and Tetraphase Pharmaceuticals, Inc., entered into an exclusive license agreement (the "PAION License") with PAION AG and its wholly owned subsidiary (collectively, "PAION"). Pursuant to the PAION License, La Jolla granted PAION an exclusive license to commercialize GIAPREZA and XERAVA in the European Economic Area, the United Kingdom and Switzerland (collectively, the "PAION Territory"). La Jolla has received an upfront cash payment of $22.5 million, less a 15% refundable withholding tax, and is entitled to receive potential commercial milestone payments of up to $109.5 million and double-digit tiered royalty payments. In addition, royalties payable under the PAION License will be subject to reduction on account of generic competition and after patent expiration in a jurisdiction. La Jolla recognized the upfront cash payment of $22.5 million as license and other revenue for the year ended December 31, 2021, and the 15% refundable withholding tax of $3.4 million was recorded as an other current asset as of December 31, 2021. Pursuant to the PAION License, PAION will be solely responsible for the future development and commercialization of GIAPREZA and XERAVA in the PAION Territory. PAION is required to use commercially reasonable efforts to commercialize GIAPREZA and XERAVA in the PAION Territory. The Company has not received any payments from PAION related to either royalties or commercial milestones.

In July 2021, the Company entered into a commercial supply agreement with PAION whereby the Company will supply PAION a minimum quantity of GIAPREZA and XERAVA through July 13, 2024. The supply agreement will automatically renew until the earlier of July 13, 2027, or until a new supply agreement is executed. During the initial 3-year term of the supply agreement, the Company will be reimbursed for direct and certain indirect manufacturing costs at cost.

Everest Medicines Limited

In February 2018, the Company entered into a license agreement with Everest, which was subsequently amended and restated (the "Everest License"). Pursuant to the Everest License, the Company granted Everest an exclusive license to develop and commercialize XERAVA for the treatment of cIAI and other indications in mainland China, Taiwan, Hong Kong, Macau, South Korea, Singapore, the Malaysian Federation, the Kingdom of Thailand, the Republic of Indonesia, the Socialist Republic of Vietnam and the Republic of the Philippines (collectively, the "Everest Territory"). The Company is eligible to receive an additional $8.0 million regulatory milestone payment and up to an aggregate of $20.0 million in sales milestone payments. The Company is also entitled to receive tiered royalties from Everest at percentages in the low double digits on sales, if any, in the Everest Territory of products containing eravacycline. Royalties are payable with respect to each jurisdiction in the Everest Territory until the latest to occur of: (i) the last-to-expire of specified patent rights in such jurisdiction in the Everest Territory; (ii) expiration of marketing or regulatory exclusivity in such jurisdiction in the Everest Territory; or (iii) 10 years after the first commercial sale of a product in such jurisdiction in the Everest Territory. In March 2021, the Company received a $3.0 million milestone payment associated with the submission of an NDA with the China NMPA for XERAVA for the treatment of cIAI in patients in China. XERAVA was approved in Singapore by the Health Science Authority in April 2020.

In May 2021, the Company entered into a commercial supply agreement with Everest whereby the Company will supply Everest a minimum quantity of XERAVA through December 31, 2023 and will transfer to Everest certain XERAVA-related manufacturing know-how. Pursuant to the supply agreement: (i) the Company has received $6.8 million of upfront payments comprised of: (1) a $4.0 million upfront technology transfer payment; and (2) a $2.8 million partial prepayment for XERAVA that is expected to be delivered to Everest during 2022; (ii) the Company has received an additional $1.0 million technology

--------------------------------------------------------------------------------

transfer payment in January 2022; and (iii) the Company will be reimbursed for direct and certain indirect manufacturing costs at 110% of cost through December 31, 2023. The Company recognized the $5.0 million of technology transfer-related payments as license and other revenue during the year ended December 31, 2021 as Everest obtained control of the XERAVA-related manufacturing know-how prior to December 31, 2021. The Company recognized the $2.8 million partial prepayment for XERAVA that is expected to be delivered to Everest during 2022 as deferred revenue as of December 31, 2021 as the performance obligation to deliver XERAVA has not yet been satisfied.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in our financial condition, expenses, results of operations, liquidity, capital expenditures or capital resources.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based on our audited consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The preparation of these audited consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in the notes to our consolidated financial statements included in Item 15 of this Annual Report on Form 10-K, we believe that the following accounting policies and estimates are most critical to understanding and evaluating our reported financial results.

Revenue Recognition

Pursuant to Financial Accounting Standards Board (the "FASB") Accounting Standards Codification ("ASC") Topic 606-Revenue from Contracts with Customers ("ASC 606"), the Company recognizes revenue when its customers obtain control of the Company's product, which typically occurs on delivery. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those goods. To determine revenue recognition for contracts with customers within the scope of ASC 606, the Company performs the following 5 steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies the relevant performance obligations.

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


    •   Chargebacks-Chargebacks are discounts the Company provides to distributors
        in the event that the sales prices to end users are below the
        distributors' acquisition price. This may occur due to a direct contract
        with a health system, a group purchasing organization ("GPO") agreement or
        a


                                       46

--------------------------------------------------------------------------------


        sale to a government facility. Chargebacks are estimated based on known
        chargeback rates and recorded as a reduction of revenue on delivery to the
        Company's customers.


    •   Discounts-The Company offers customers various forms of incentives and
        consideration, including prompt-pay and other discounts. The Company
        estimates discounts primarily based on contractual terms. These discounts
        are recorded as a reduction of revenue on delivery to the Company's
        customers.


    •   Returns-The Company offers customers a limited right of return, generally
        for damaged or expired product. The Company estimates returns based on an
        internal analysis, which includes actual experience. The estimates for
        returns are recorded as a reduction of revenue on delivery to the
        Company's customers.


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


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

The Company will continue to assess its estimates of variable consideration as it accumulates additional historical data and will adjust these estimates accordingly.

Business Combinations

The Company accounts for business combinations using the acquisition method pursuant to FASB ASC Topic 805. This method requires, among other things, that results of operations of acquired companies are included in La Jolla's financial results beginning on the respective acquisition dates, and that assets acquired and liabilities assumed are recognized at fair value as of the acquisition date. Intangible assets acquired in a business combination are recorded at fair value using a discounted cash flow model. The discounted cash flow model requires assumptions about the timing and amount of future net cash flows, the cost of capital and terminal values from the perspective of a market participant. Any excess of the fair value of consideration transferred (the "Purchase Price") over the fair values of the net assets acquired is recognized as goodwill. Contingent consideration liabilities are recognized as part of the Purchase Price at the estimated fair value on the acquisition date. Subsequent changes to the fair value of contingent consideration liabilities will be included in other (expense) income, net in the consolidated statements of operations. The fair value of assets acquired and liabilities assumed in certain cases may be subject to revision based on the final determination of fair value during a period of time not to exceed 12 months from the acquisition date. Legal costs, due diligence costs, business valuation costs and all other acquisition-related costs are expensed when incurred.

Intangible Assets

Intangible assets acquired in a business combination are initially recorded at fair value. Intangible assets with a definite useful life are amortized on a straight-line basis over the estimated useful life of the related assets. Intangible assets with an indefinite useful life are not amortized.

The Company reviews its intangible assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If such



                                       47

--------------------------------------------------------------------------------

circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the asset, including its eventual residual value, is compared to the carrying value to determine whether impairment exists. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values. Fair value is estimated through discounted cash flow models to project cash flows from the asset.

Goodwill

Goodwill represents the excess of the Purchase Price over the fair value of the net assets acquired as of the acquisition date. Goodwill has an indefinite useful life and is not amortized.

The Company reviews its goodwill for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the Company may exceed its fair value. The Company may first assess qualitative factors to determine whether it is more likely than not that the fair value of the Company is less than its carrying amount, including goodwill. If that is the case, the Company performs a quantitative impairment test, and, if the carrying amount of the Company exceeds its fair value, then the Company will recognize an impairment charge for the amount by which its carrying amount exceeds its fair value, not to exceed the carrying amount of the goodwill. The Company has an option to bypass the qualitative assessment and proceed directly to performing the quantitative impairment test.

Accrued Expenses

As part of the process of preparing the financial statements, we are required to estimate accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed by service providers and estimating the level of service performed and the associated cost incurred for services that have not yet been invoiced. We make estimates of accrued expenses as of each balance sheet date in the financial statements based on facts and circumstances known at that time. We periodically confirm the accuracy of recorded estimates with the service providers and make adjustments, if necessary.

We base our accrued expenses on our estimates of the services received and efforts expended pursuant to our contractual arrangements. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepayment accordingly. The financial terms of our contractual agreements may be subject to interpretation, and the timing of payment relative to the timing of services rendered may vary.

Interest Expense

The deferred royalty obligation royalty from our financing agreement (the "Royalty Agreement") with HealthCare Royalty Partners, which was entered into by our wholly owned subsidiary, La Jolla Pharma, LLC, is repaid based on the net sales of GIAPREZA. Interest expense and the amortization of issuance costs related to the deferred royalty obligation are recognized over the expected repayment term using the effective interest method. The assumptions used in determining the expected repayment term of the deferred royalty obligation require us to make estimates that could impact the effective interest rate. Each reporting period, we update our estimate of accrued interest expense under the Royalty Agreement based on actual and forecasted net sales of GIAPREZA. Changes in interest expense resulting from changes in the effective interest rate, if any, are recorded on a prospective basis.

Recent Accounting Pronouncements

Recent accounting pronouncements are disclosed in Note 2 to the accompanying audited consolidated financial statements included in Item 15 of this Annual Report on Form 10-K.
