These consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and in accordance with the rules and regulations of the United States Securities and Exchange Commission, or SEC. The accounts of the Company’s wholly owned subsidiaries are included in these consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications from previously issued financial statements have been made to conform to the current presentation.

The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, including disclosure of contingent assets and contingent liabilities, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, among other things, revenue recognition, purchase price allocation, stock-based compensation, inventory costs, impairments of equity investments, long-lived assets, goodwill and other intangible assets, liabilities and accruals, including contingent consideration, and the valuation of deferred tax assets. The Company’s critical accounting estimates are those that are both most important to the Company’s consolidated financial condition and results of operations and require the most difficult, subjective or complex judgments on the part of management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Because of the uncertainty of factors surrounding the

The Company’s sources of revenue include (i) sales of EXPAREL in the U.S., European Union, or E.U. and U.K.; (ii) sales of ZILRETTA in the U.S.; (iii) sales of iovera° in the U.S., Canada and the E.U.; (iv) sales of, and royalties on, its bupivacaine liposome injectable suspension for veterinary use and (v) license fees and milestone payments. Royalty revenues are from the Company’s collaborative licensing agreements. See Note 4, Revenue, for further information on the Company’s accounting policies related to revenue from contracts with customers.

The Company’s collaboration agreements generally involve a license to the Company’s products. In determining when to recognize the revenue under a collaboration agreement, the Company must assess whether the license is distinct, which depends upon whether the customer can benefit from the license and whether the license is separate from other performance obligations in the agreement. If the license is distinct, the Company must further assess whether the customer has a right to access or a right to use the license depending on whether the functionality of the license is expected to substantively change over time. If the license is not expected to substantively change, the revenue is recognized at the point in time when the license is provided. If the license is expected to substantively change, the revenue is recognized over the license period.

Revenue recognition from milestone payments is dependent upon the facts and circumstances surrounding the milestone payments. Milestone payments based on a non-sales metric such as a development-based milestone (e.g. obtaining regulatory approval) represent variable consideration and would be included in the transaction price subject to any constraints. If the milestone payments relate to future development, the timing of recognition depends upon historical experience and the significance a third-party has on the outcome. For milestone payments to be received upon the achievement of a sales threshold, the revenue from the milestone payments is recognized at the later of when the actual sales are incurred or the performance obligation to which the sales relate has been satisfied.

The Company sells EXPAREL through a drop-ship program under which orders are processed through wholesalers (including AmerisourceBergen Health Corporation, Cardinal Health, Inc. and McKesson Drug Company), but shipments of the product are sent directly to individual accounts, such as hospitals, ambulatory surgery centers and individual physicians. The Company also sells EXPAREL directly to ambulatory surgery centers and physicians. The Company sells ZILRETTA primarily to specialty distributors and a specialty pharmacy, who then subsequently resell ZILRETTA to physicians, clinics and certain medical centers or hospitals. The Company also contracts directly with healthcare providers and intermediaries such as Group Purchasing Organizations, or GPOs. The Company sells its bupivacaine liposome injectable suspension for veterinary use to a third-party licensee in the U.S. and sells iovera° directly to end users.

Research and development expenditures are expensed as incurred. These include both internal and external costs, of which a significant portion of development activities are outsourced to third parties, including contract research organizations. Clinical trial costs are accrued over the service periods specified in contracts and adjusted as necessary based on an ongoing review of the level of effort and actual costs incurred. Research and development costs are presented net of reimbursements from commercial partners.

The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to basis differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company’s stock-based compensation consists of grants of stock options and restricted stock units, or RSUs, to employees, consultants and non-employee directors, in addition to the opportunity for employees to participate in an employee stock purchase plan. The expense associated with these programs is recognized in the Company’s consolidated statements of operations based on their fair values as they are earned under the applicable vesting terms or the length of an offering period.

In calculating the estimated fair value of stock options and employee stock purchase plan share options granted, the Company uses the Black-Scholes option valuation model, or Black-Scholes model, which requires the consideration of the following variables for purposes of estimating fair value in addition to the closing price of the Company’s common stock on the date of grant:

The Company utilizes its historical volatility data to determine expected volatility over the expected option term. The Company uses an expected term based on its historical data from stock option activity. The risk-free interest rate is based on the implied yield on U.S. Department of the Treasury zero-coupon bonds for periods commensurate with the expected term of the options. The dividend yield on the Company’s common stock is estimated to be zero as the Company has not declared or paid any dividends since inception, nor does it have any intention to do so in the foreseeable future. Additionally, the Company’s ability to declare and pay a dividend in the future could be limited per the agreements governing its indebtedness. The Company records forfeitures of grants as they occur rather than estimating forfeitures during each reporting period.

All highly liquid investments with maturities of 90 days or less when purchased are considered cash equivalents. Cash equivalents include corporate debt securities, asset-backed securities and money market funds. As of December 31, 2022, the carrying value of money market funds was $42.6 million. As of December 31, 2021, the carrying value of money market funds was $223.0 million, commercial paper was $19.0 million and asset-backed securities was $2.6 million. The carrying values approximate fair value as of December 31, 2022 and 2021.

Short-term available-for-sale investments consist of asset-backed securities collateralized by credit card receivables, investment grade commercial paper, corporate and government bonds, and other bonds issued in the U.S. (and denominated in the U.S. dollar) by foreign entities, all with maturities of greater than three months, but less than one year. Noncurrent available-for-sale investments consist of corporate and government agency bonds with maturities greater than one year. The Company evaluates the classification of its investments at the time of purchase and re-evaluates such determination at each balance sheet date, which includes an assessment of the intent to hold the available-for-sale securities. The Company’s investment policy sets minimum credit quality criteria and maximum maturity limits on its investments to provide for preservation of capital, liquidity and a reasonable rate of return. The Company classifies its investments as available-for-sale. Available-for-sale securities are recorded at fair value, based on current market valuations. Unrealized holding gains and losses on available-for-sale securities (except for credit losses) are excluded from net income (loss) and are reported as a separate component of accumulated other comprehensive (loss) income until realized. Realized gains and losses are included in interest income in the consolidated statements of operations and are derived using the specific identification method for determining the cost of the securities sold. The Company evaluates whether a credit loss exists, and in the event a credit loss does exist, the credit loss is recognized in the consolidated statements of operations based on the amount that the fair value is less than the amortized cost.

Inventories consist of finished goods held for sale and distribution, raw materials and work in process. Inventories are stated at the lower of cost, which includes amounts related to material, labor and overhead, or net realizable value, and is determined using the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory to identify obsolete, slow-moving, or otherwise unsalable inventories, and establishes allowances for situations in which the cost of the inventory is not expected to be recovered.

Depreciation of fixed assets is provided over their estimated useful lives on a straight-line basis. The Company periodically reviews these useful lives relative to physical factors, economic factors and industry trends. If there are changes in the planned use of property or equipment, the useful lives assigned to these assets may need to be shortened, resulting in the recognition of accelerated depreciation expense in future periods. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the related remaining lease terms. Useful lives by asset category are as follows:


Asset Category						Useful Life
Computer equipment and software						1 to 3 years
Office furniture and equipment						5 years
Manufacturing and laboratory equipment						5 to 10 years

The Company has contractual obligations stemming from certain of its lease agreements to return leased space to its original condition upon termination of such lease agreements. The Company records its asset retirement obligations, or ARO, along with a corresponding capital asset in an amount equal to the estimated fair value of the ARO, based on the present value of expected future cash flows. In subsequent periods, the Company records expense to accrete the ARO to its full value. Each ARO capital asset is depreciated over the depreciable term of the associated fixed asset.

The Company recognizes right-of-use, or ROU, assets and lease liabilities at the commencement of its lease agreements. The leases are evaluated at commencement to determine whether they should be classified as operating or financing leases. Lease costs associated with operating leases are recognized on a straight-line basis, while lease costs for financing leases are recognized over the lease term using the effective interest method. The Company does not have any financing leases. The amount of ROU assets and lease liabilities to be recognized is impacted by the type of lease payments, the lease term and the

In a business combination, the acquisition method of accounting requires that the assets acquired and liabilities assumed be recorded as of the date of the acquisition at their respective fair values, with some exceptions. Assets acquired and liabilities assumed in a business combination that arise from contingencies are generally recognized at fair value. If fair value can be determined, the asset or liability is recognized; if fair value is not determinable, then no asset or liability is recognized. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Acquired in-process research and development, or IPR&D, is recognized at fair value and initially characterized as an indefinite-lived intangible asset, irrespective of whether the acquired IPR&D has an alternative future use. If the acquired net assets do not constitute a business under the acquisition method of accounting, the transaction is accounted for as an asset acquisition and no goodwill is recognized. In an asset acquisition, the amount allocated to acquired IPR&D with no alternative future use is recorded as an expense at the acquisition date.

Any excess of the purchase price (consideration transferred) over the estimated fair values of net assets acquired is recorded as goodwill. Transaction costs and costs to restructure the acquired company are expensed as incurred. The operating results of the acquired business are reflected in the Company’s consolidated financial statements after the closing date of the acquisition.

Subsequent to an acquisition, the Company measures contingent consideration arrangements at fair value at each reporting period, with changes in fair value recognized in the consolidated statements of operations as acquisition-related charges (gains). Changes in contingent consideration can result from changes in the assumed achievement and timing of estimated sales, costs of goods sold and regulatory approvals. In the absence of new information, changes in fair value reflect the passage of time towards achievement or expiration of the milestones, and are accreted to the period in which payments are expected to be made.

Intangible assets with definite useful lives are amortized on a straight-line basis over their estimated useful lives and are recorded at cost, net of accumulated amortization. Indefinite-lived intangible assets are tested for impairment at least annually or when a triggering event occurs that could indicate a potential impairment exists. Impairment charges are recognized to the extent the carrying value exceeds its fair value.

Management reviews long-lived assets, including fixed assets and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Diluted net income (loss) per common share is calculated by dividing net income (loss) available (attributable) to common stockholders as adjusted for the effect of dilutive securities, if any, by the weighted average number of shares of common stock and dilutive common stock outstanding during the period. Potential common shares include the shares of common stock issuable upon the exercise of outstanding stock options, the RSUs expected to vest, and the shares of common stock expected to be purchased under the Company’s employee stock purchase plan (using the treasury stock method), and the potential common shares issuable upon conversion of the convertible senior notes using the if-converted method. Under the if-converted method, adjustments are made to the diluted net income (loss) per common share calculation as if the Company had converted the convertible senior notes on the first day of each period presented. Adjustments to the numerator are made to add back the interest expense associated with the convertible senior notes on a post-tax basis.

The balance sheet accounts of the Company’s foreign subsidiaries with functional currencies other than the U.S. Dollar are translated using the exchange rate at each respective balance sheet date. Revenues and expenses are translated using the average exchange rates for each calendar month during the year. Translation adjustments are recorded as a component of accumulated other comprehensive (loss) income in the consolidated financial statements. Gains or losses from foreign currency exchanges are recorded in other, net in the consolidated statements of operations.

The Company is managed and operated as a single business focused on the development, manufacture, marketing, distribution and sale of non-opioid pain management and regenerative health solutions. The Company is managed by a single management team, and, consistent with its organizational structure, the Chief Executive Officer—who is the Company’s chief operating decision maker—manages and allocates resources at a consolidated level. Accordingly, the Company views its business as one reportable operating segment to evaluate its performance, allocate resources, set operational targets and forecast its future financial results.
