Disclosure Of Notes And Other Explanatory Information [Abstract]  
Selected accounting policies Selected accounting policies
Basis of preparation
The accompanying Consolidated Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) (“IFRS Accounting Standards”). Alcon's principal accounting policies are described in this Note.
Principles of consolidation and equity accounting
The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. In the event that the Company has an interest in another entity that is not wholly owned, the assets, liabilities, results of operations and cash flows of such entity are included in the Company's Consolidated Financial Statements, if the Company directly or indirectly has control over such entity. The Consolidated Financial Statements of the Company are prepared in accordance with IFRS as issued by the IASB. They are prepared in accordance with the historical cost convention except for items that are required to be accounted for at fair value. All intercompany transactions and accounts within Alcon were eliminated.
The Company's financial year-end is December 31, which is also the annual closing date of the individual entities' financial statements incorporated into the Consolidated Financial Statements.
Associated companies are all entities over which Alcon has a significant influence but not control or joint control. This is generally the case where Alcon holds between 20% and 50% of an entity's voting rights. Alcon can also have significant influence over an investee where it holds less than 20% of the voting rights if Alcon has significant transactions with the investee, Alcon has influence over the investee’s policy making decisions through Board representation, Alcon shares significant technical information with the investee or Alcon exchanges personnel with the investee. Investments in associated companies are accounted for using the equity method from the date when the investee is determined to be an associated company until the date when Alcon loses significant influence over the investee. Under the equity method, the investment is initially recognized at cost, and the carrying amount is subsequently increased or decreased, to recognize Alcon's share of profit or loss and other comprehensive income of the associated company after the date of initial recognition. Alcon eliminates its share of profit/(loss) from unrealized gains/(losses) from its transactions with associated companies against the carrying amount of the investment. Dividends received or receivable from associated companies are recognized as a reduction in the carrying amount of the investment.
The use of the equity method is discontinued from the date when the investee is determined to no longer be an associated company. The investment retained after cessation of the equity method is remeasured at fair value, and any gain or loss on such remeasurement and disposal of the investment is recognized in the Consolidated Income Statement.
The carrying amounts of investments in associated companies are tested for impairment when triggering events are identified.
Use of estimates and assumptions
The preparation of Consolidated Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates.
Foreign currencies
The Consolidated Financial Statements are presented in US dollars ("USD"). The functional currency of individual entities incorporated into the Consolidated Financial Statements is generally the local currency of the respective entity. The functional currency used for the reporting of certain Swiss entities is USD instead of their respective local currencies. This reflects the fact that the cash flows and transactions of these entities are primarily denominated in this currency.
For entities not operating in hyperinflationary economies, the entities results, financial position and cash flows that do not have USD as their functional currency are translated into USD using the following exchange rates:
Income, expense and cash flows using for each month the average exchange rate, with the USD values for each month being aggregated during the year;
Balance sheet using period-end exchange rates; and
Resulting exchange rate differences are recognized in other comprehensive income.
The hyperinflationary economies in which Alcon operates are Argentina, Turkey and Venezuela. Argentina and Venezuela were hyperinflationary for all years presented. Turkey became hyperinflationary effective April 1, 2022, requiring retroactive implementation from January 1, 2022 of hyperinflationary accounting.
Hyperinflationary accounting under IAS 29, Financial Reporting in Hyperinflationary Economies, requires restatement of non-monetary assets and liabilities to the general price index at the end of the period. The income statement and components of comprehensive income are restated for changes in general price index from the period in which the transactions were initially recorded to the end of the reporting period, with the restated amounts translated using period-end exchange rates. Alcon records the impacts of applying IAS 29 in "Other reserves" in the Consolidated Statement of Changes in Equity and "Other financial income & expense" in the Consolidated Income Statement.
Acquisition of assets
Assets separately acquired are initially recognized on the balance sheet at cost if they meet the criteria for capitalization. The capitalized cost of the asset includes the purchase price and any directly attributable costs for bringing the asset into the condition to operate as intended. Expected costs for obligations to dismantle and remove property, plant and equipment when it is no longer used are included in their cost.
Property, plant and equipment
Property, plant and equipment are depreciated on a straight-line basis over their estimated useful lives. Freehold land is not depreciated. The related depreciation expense is included in the costs of the functions using the asset or "Cost of net sales" in the Consolidated Income Statement.
Property, plant and equipment are assessed for impairment at the cash generating unit ("CGU") level whenever there is an indication that the balance sheet carrying amount may not be recoverable using cash flow projections for the useful life.
The following table shows the respective useful lives for property, plant and equipment:
 Useful life
Buildings and improvements
10 to 40 years
Machinery and other equipment 
Machinery and equipment
5 to 20 years
Furniture and vehicles
5 to 10 years
Computer hardware
3 to 7 years
Business combinations
The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary may include:
Fair values of the assets transferred;
Liabilities incurred to the former owners of the acquired business;
Equity interests issued by the Company;
Fair value of an asset or liability resulting from a contingent consideration arrangement; and
Fair value of any pre-existing equity interest in the subsidiary.
Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The excess of the consideration transferred over the fair value of the net identifiable assets acquired is recorded as goodwill, or directly in the income statement if it is a bargain purchase. Alcon primarily uses net present value techniques, utilizing post-tax cash flows and discount rates in estimating the fair value of identifiable assets acquired when allocating the purchase consideration paid for the acquisition. The estimates of the fair values involve significant judgment by management and include assumptions with measurement uncertainty such as the amount and timing of projected cash flows, long-term sales forecasts, the timing and probability of regulatory and commercial success and the discount rate.
Acquisition related costs are expensed as incurred.
Alcon may elect on a transaction-by-transaction basis to apply the optional concentration test to assess whether a transaction qualifies as a business. Under the test, when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, Alcon will account for the transaction as an asset purchase and not a business combination.
If the concentration test is not met, or Alcon elects not to apply this optional test, Alcon will perform an assessment focusing on the existence of inputs and processes that have the ability to create outputs to determine whether the transaction is an asset purchase or a business combination.
Goodwill and intangible assets
The annual impairment testing date is Alcon's financial year-end, December 31.
Goodwill
Goodwill arises in a business combination and is the excess of the consideration transferred to acquire a business over the underlying fair value of the net identified assets acquired. It is allocated to groups of CGUs which are usually represented by the reportable segments, which are the same as Alcon's operating segments. Goodwill is tested for impairment annually at the level of these groups of CGUs, and any impairment charges are recorded under "Other expense" in the Consolidated Income Statement.
Intangible assets available-for-use
Alcon has the following classes of available-for-use intangible assets: Currently marketed products, Marketing know-how, Technologies, Other intangible assets (including software) and the Alcon brand name.
Currently marketed products represent the composite value of acquired intellectual property, patents, and distribution rights and product trade names.
Marketing know-how represents the value attributable to the expertise acquired for marketing and distributing Alcon surgical products.
Technologies represent identified and separable acquired know-how used in the research, development and production processes.
Significant investments in internally developed and acquired software are capitalized and included in the "Other" category and amortized once available for use.
The Alcon brand name is shown separately as it is the only Alcon intangible asset that is available for use with an indefinite useful life. Alcon considers it appropriate that the brand name has an indefinite life since the branded products have a history of strong revenue and cash flow performance, and Alcon has the intent and ability to support the brand with spending to maintain its value for the foreseeable future.
Except for the Alcon brand name, intangible assets available for use are amortized over their estimated useful lives on a straight-line basis and evaluated for potential impairment whenever facts and circumstances indicate that their carrying value may not be recoverable. The Alcon brand name is not amortized, but evaluated for potential impairment annually.
The following table shows the respective useful lives for available-for-use intangible assets and the location in the Consolidated Income Statement in which the respective amortization and any potential impairment charge is recognized:

Alcon brand nameNot amortized, indefinite useful life"Other expense"
Acquired In-Process Research & Development ("IPR&D")
Acquired research and development intangible assets, which are still under development and have accordingly not yet obtained marketing approval, are recognized as IPR&D.
IPR&D is not amortized, but evaluated for potential impairment on an annual basis or when facts and circumstances warrant. IPR&D is considered impaired when its balance sheet carrying amount exceeds its estimated recoverable amount, which is defined as the higher of its fair value less costs of disposal ("FVLCOD") and its value in use ("VIU"). Usually, Alcon applies the FVLCOD method for its impairment assessments. Under this approach when evaluating IPR&D for potential impairment, FVLCOD is estimated using net present value techniques utilizing post-tax cash flows and discount rates as there are no direct or indirect observable prices in active markets for identical or similar assets. The estimates used in calculating the net present values involve significant judgment by management and include assumptions with measurement uncertainty such as, the amount and timing of projected cash flows, long-term sales forecasts, discount rate, and the timing and probability of regulatory and commercial success. In the limited cases where the VIU method would be applied, net present value techniques would be applied using pre-tax cash flows and discount rates.
Any impairment charge is recorded in the Consolidated Income Statement under "Research & development".
Once a project included in IPR&D has been successfully developed it is transferred to the "Currently marketed products" category.
Impairment of goodwill, Alcon brand name and definite lived intangible assets
A CGU to which goodwill has been allocated (reportable segments) is considered impaired when its carrying amount, including the goodwill, exceeds its recoverable amount, which is defined as the higher of its FVLCOD and its VIU. If the recoverable amount of the reportable segment is less than its carrying amount, an impairment loss shall be recognized. The impairment loss shall be allocated to reduce the carrying amount of any goodwill allocated to the reportable segment first, with any remaining impairment loss allocated to other assets of the reportable segment on a pro-rata basis of their carrying amount.
An intangible asset other than goodwill is considered impaired when its balance sheet carrying amount exceeds its estimated recoverable amount, which is defined as the higher of its FVLCOD and its VIU. If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset shall be reduced to its recoverable amount. That reduction is an impairment loss. Usually, Alcon applies the FVLCOD method for its impairment assessment. In most cases, no direct or indirect observable market prices for identical or similar assets are available to measure the FVLCOD. Therefore, an estimate of FVLCOD is based on net present value techniques utilizing post-tax cash flows and discount rates. In the limited cases where the VIU method would be applied, net present value techniques would be applied using pre-tax cash flows and discount rates.
FVLCOD reflects estimates of assumptions that market participants would be expected to use when pricing the asset or CGUs, and for this purpose management considers the range of economic conditions that are expected to exist over the remaining useful life of the asset.
The estimates used in calculating the net present values involve significant judgment by management and include assumptions with measurement uncertainty, such as the following:
Amount and timing of projected cash flows;
Long-term sales forecasts, including sales growth rates;
Royalty rate for the Alcon brand name;
Terminal growth rate; and
Discount rate.
Other assumptions used in the net present values calculation include:
Future tax rate;
Actions of competitors (launch of competing products, marketing initiatives, etc.); and
Outcome of R&D activities and forecast of related costs (future product developments).
Generally, for intangible assets with a definite useful life Alcon uses cash flow projections for the whole useful life of these assets. For goodwill and the Alcon brand name, Alcon generally utilizes cash flow projections for a five-year period based on management forecasts, with a terminal value based on cash flow projections considering the long-term expected growth rates and impact of demographic trends of the population to which Alcon products are prescribed, for later periods. Probability-weighted scenarios are typically used.
Discount rates used consider Alcon estimated weighted average cost of capital adjusted for specific country and currency risks associated with cash flow projections to approximate the weighted average cost of capital of a comparable market participant. Actual cash flows and values could vary significantly from forecasted future cash flows and related values derived using net present value techniques.
Cash and cash equivalents
Cash and cash equivalents includes cash on hand, deposits held at call with financial institutions, and other short-term and highly liquid investments. Other short-term and highly liquid investments are classified as cash and cash equivalents when original or weighted-average maturities are three months or less and amounts are readily convertible to known amounts of cash which are subject to an insignificant risk of changes in value. Bank overdrafts are usually presented within current financial debts on the Consolidated Balance Sheet except in cases where a right of offset has been agreed with a bank which then allows for presentation on a net basis.
Financial assets
Non-current financial assets such as the long-term note receivable, certain other financial assets, loans and long-term receivables from customers, primarily related to surgical equipment sales arrangements, VAT receivables, advances and other deposits, are carried at amortized cost, which reflects the time value of money, less any allowances for uncollectable amounts.
Alcon assesses on a forward-looking basis the expected credit losses associated with its non-current financial assets valued at amortized cost.
Purchased or originated credit-impaired financial assets are financial assets that are credit-impaired on initial recognition with one or more events that have a detrimental impact on the estimated future cash flows of those financial assets. The interest income of the financial assets is calculated by applying the credit-adjusted effective interest rate to the amortized cost of the financial asset. The calculation does not revert to the gross basis even if the credit risk of the financial asset subsequently improves so that the financial asset is no longer credit-impaired. Interest income is recognized in "Other financial income and expense" in the Consolidated Income Statement.
The lifetime expected credit loss ("ECL") of the purchased or originated credit-impaired financial assets is analyzed at inception and utilized in calculating the credit-adjusted effective interest rate, with no Day 1 impact on the carrying value of the financial assets. The value of any collateral related to the financial assets is considered in estimating the lifetime ECL at inception. For purchased or originated credit-impaired financial assets, a credit-adjusted effective interest rate is calculated by discounting the estimated future cash flows, including ECLs, to the amortized cost of the debt instrument on initial recognition. Any change in the lifetime ECL from inception would be reflected as a credit loss in the Consolidated Income statement.
For loans, VAT receivables, advances and other deposits valued at amortized cost, impairments, which are based on their expected credit losses, and exchange rate losses are included in "Other expense" in the Consolidated Income Statement
and exchange rate gains and interest income, using the effective interest rate method, are included in "Other income" in the Consolidated Income Statement.
For long-term receivables from customers, provisions for uncollectable amounts, which are based on their expected credit losses, are recorded as marketing and selling costs recognized in the Consolidated Income Statement within "Selling, general & administration" expenses.
Fund investments are valued at fair value through profit and loss ("FVPL"). Unrealized or realized gains and losses, including exchange gains and losses, are recognized in the Consolidated Income Statement in "Other income" for gains and "Other expense" for losses.
Equity investments, including equity securities and convertible notes receivable held as strategic investments are generally designated at the date of acquisition as financial assets valued at fair value through other comprehensive income ("FVOCI") with no subsequent recycling through profit and loss. Unrealized gains and losses, including exchange gains and losses, are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive Income. They are reclassified to "Other reserves" when the equity investment is sold. If these equity securities and convertible notes receivable are not designated at the date of acquisition as financial assets valued at FVOCI, they are valued at FVPL, as described above for fund investments. Changes in fair value of options to acquire development stage companies are charged to Research and development expense.
Derivative financial instruments are initially recognized in the Consolidated Balance Sheet at fair value and are remeasured to their current fair value at the end of each subsequent reporting period. The valuation of forward exchange rate contracts and foreign exchange swaps are based on the discounted cash flow model, using interest curves and spot rates at the reporting date as observable inputs. Unsettled forward contracts and swaps are measured at fair value at quarter-end with changes in fair value recorded to the Consolidated Income Statement as unrealized gains or losses in "Other financial income & expense". Settled forward contracts and swaps are measured at maturity date at fair value with corresponding realized gains or losses recognized in the Consolidated Income Statement in "Other financial income & expense". No hedge accounting is applied for these arrangements.
Inventories
Inventory is valued at the lower of acquisition or production cost determined on a first-in, first-out basis and net realizable value. This value is used for the "Cost of net sales" and "Cost of other revenues" in the Consolidated Income Statement. Unsalable inventory is fully written off in the Consolidated Income Statement under "Cost of net sales" and "Cost of other revenues".
Trade receivables
Trade receivables are initially recognized at their invoiced amounts, including any related sales taxes less adjustments for estimated revenue deductions such as chargebacks and cash discounts.
Provisions for expected credit losses are established using an expected credit loss model ("ECL"). The provisions are based on a forward-looking ECL, which includes possible default events on the trade receivables over the entire holding period of the trade receivable. These provisions represent the difference between the trade receivable's carrying amount and the estimated net collectible amount. Charges for doubtful trade receivables are recorded as marketing and selling costs recognized in the Consolidated Income Statement within "Selling, general & administration" expenses.
Leases
As lessee, Alcon assesses whether a contract contains a lease at inception or modification of a contract based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Alcon allocates contractual payments between lease and non-lease components based on their relative stand-alone price. Alcon recognizes a right-of-use asset and a corresponding lease liability for all arrangements in which it is a lessee, except for leases with a term of twelve months or less (short-term leases) and low value leases for which Alcon has elected the recognition exemptions allowed under IFRS 16.
Right-of-use assets
Right-of-use assets are initially recognized at cost, which is comprised of the amount of the initial measurement of the corresponding lease liabilities, adjusted for any lease payments made at or prior to the commencement date of the lease, lease incentives received and initial direct costs incurred, as well as any expected costs for obligations to dismantle and remove right-of-use assets when they are no longer used.
Right-of-use assets are depreciated on a straight-line basis over the shorter of the useful life of the right-of-use asset or the end of the lease term.
Right-of-use assets are assessed for impairment whenever there is an indication that the balance sheet carrying amount may not be recoverable using cash flow projections for the useful life.
Lease liabilities
Lease liabilities are accounted for at amortized cost and are initially measured at the present value of future lease payments and are classified as current or non-current based on the due dates of the underlying principal payments. In determining the lease term, Alcon evaluates the renewal options and termination options reasonably certain to be exercised. Lease payments are discounted using the interest rate implicit in the lease or, if not readily determinable, the incremental borrowing rate Alcon would be expected to pay within the respective markets, on a borrowing with a similar term and security. Interest in the period is recorded within "Interest expense" in the Consolidated Income Statement.
Lease liabilities are remeasured for changes in estimated lease term, future lease payments arising from a change in an index or rate, amounts expected to be payable under a residual value guarantee, or in assessment of whether Alcon will exercise a purchase, extension or termination option. Changes to initial lease contract terms are assessed to determine their impact on the scope of lease, and any modifications increasing the scope of the lease are treated as new contracts under the initial measurement principles, while modifications that do not increase or that decrease the scope of the lease result in an adjustment to the right-of-use asset which is remeasured as of the date of the modification.
Principal payments made on lease liabilities and any initial direct costs paid are classified as financing cash outflows, while interest payments are classified as operating cash outflows.
Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in the Consolidated Income Statement and are classified as cash flows from operating activities.
Legal liabilities
Alcon is subject to contingencies arising in the ordinary course of business such as patent litigation and other product-related litigation, commercial litigation, and governmental investigations and proceedings. Provisions are recorded where a reliable estimate can be made of the probable outcome of legal or other disputes.
Contingent consideration
In a business combination, it is necessary to recognize contingent future payments to previous owners representing contractually defined potential amounts as a liability. Usually for Alcon, these are linked to development or commercial milestones related to certain assets and are recognized as a financial liability at their fair value, which is then re-measured at each subsequent reporting date.
For the determination of the fair value of a contingent consideration, various unobservable inputs are used. A change in these inputs might result in a significantly higher or lower fair value measurement. The inputs used are, among others, the timing and probability of regulatory and commercial success, sales forecast and assumptions regarding the discount rate, timing and different scenarios of triggering events. The significance and usage of these inputs to each contingent consideration may vary due to differences in the timing and triggering events for payments or in the nature of the asset related to the contingent consideration. These estimations typically depend on factors such as technical milestones or market performance and are adjusted for the probability of their likelihood of payment, and if material, appropriately discounted to reflect the impact of time.
Changes in the fair value of contingent consideration liabilities in subsequent periods are recognized in the Consolidated Income Statement in "Cost of net sales" for currently marketed products and in "Research & development" for IPR&D.
The effect of unwinding the discount over time is recognized in "Interest expense" in the Consolidated Income Statement.
Alcon accounts for variable or contingent consideration associated with asset acquisitions using the cost accumulation model. At the date of the asset acquisition, the intangible asset is initially recognized at the amount paid. Variable payments are subsequently capitalized as part of the cost of the asset when paid, on the basis that such payments represent the direct cost of acquisition.
Defined benefit pension plans and other post-employment benefits
The liability or asset recognized in the balance sheet in respect of defined benefit pension plans and other post-employment benefits is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.
The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and
that have terms approximating the terms of the related obligation. In countries where there is no sufficient market for such bonds, the market rates on government bonds are used.
The current service cost for such post-employment benefit plans is included in the personnel expenses of the various functions where the associates are employed. The net interest on the net defined benefit liability is recognized as "Other expense" or "Other income". The net interest cost is calculated by applying the discount rate to the net balance of the defined benefit obligation and the fair value of plan assets. Past service cost is recognized as "Other expense" or "Other income" in the Consolidated Income Statement for the change in the present value of a defined benefit obligation for employee service in prior periods resulting from a plan amendment or a curtailment.
Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.
Defined contribution plans
For defined contribution plans, Alcon contributes to publicly or privately administered plans. Alcon has no further payment obligations once the contributions have been paid. The contributions are included in the personnel expenses of the various functions where the associates are employed.
Financial debts
Financial debts are initially recognized at fair value, net of transaction costs incurred. Financial debts are subsequently measured at amortized cost. Any difference between the proceeds (net of transaction costs and discounts) and the redemption amount is recognized in the Consolidated Income Statement over the period of the financial debts using the effective interest method. Fees paid on the establishment of credit facilities are recognized as transaction costs of the financial debt to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw down occurs. To the extent that there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalized as a prepayment for liquidity services and amortized over the period of the facility to which it relates, and is recognized in "Other financial income & expense" in the Consolidated Income Statement.
Financial debts are derecognized from the balance sheet when the obligation specified in the contract is discharged, cancelled or expired. The difference between the carrying amount of a financial debt that has been extinguished and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognized in "Other financial income & expense" in the Consolidated Income Statement.
Interest paid on financial debts is classified as operating activities in the Consolidated Statement of Cash Flows. Proceeds and repayments of borrowings with due dates of three months or less are presented net as financing activities in the Consolidated Statement of Cash Flows. Financial debts are classified as current liabilities unless Alcon has an unconditional right and intent to defer the settlement of the liability for at least twelve months after the reporting period.
Revenue
Net sales to third parties
Revenue on the sale of Alcon products and services, which is recorded as "Net sales to third parties" in the Consolidated Income Statement, is recognized when a contractual promise to a customer (i.e., a performance obligation) has been fulfilled by transferring control over the promised goods and services to the customer, substantially all of which is at the point in time of shipment to or receipt of the products by the customer or when the services are performed. If contracts contain customer acceptance provisions, revenue would be recognized upon the satisfaction of acceptance criteria. The amount of revenue to be recognized is based on the consideration Alcon expects to receive in exchange for its goods and services. If a contract contains more than one performance obligation, the consideration is allocated based on the relative stand-alone selling price of each performance obligation.
Surgical equipment may be sold together with other products and services under a single contract and may be structured as an outright cash sale, an installment sale, or a lease. Surgical equipment installment sales and leases have a fixed payment amount which the customer may pay either in fixed intervals or as the customer purchases consumables and/or implantables. Revenues are recognized upon satisfaction of each of the performance obligations in the contract and the consideration is allocated based on the relative stand-alone selling price of each performance obligation.
Surgical equipment revenue from outright cash sales and installment sales arrangements is recognized at the point in time when control is transferred to the customer. The current portion of long-term receivables from customers and long-term receivables from customers for installment sales arrangements are recorded in "Other current assets" (see "Current portion of long-term receivables from customers" in Note 14) and "Financial
assets" (see "Long-term receivables from customers" in Note 11), respectively. Financing income for installment sales arrangements longer than twelve months is recognized over the term of the arrangement in "Other income". Alcon applies the practical expedient under IFRS 15 to installment sales arrangements that are twelve months or less in duration.
In addition to cash and installment sales, revenue is recognized under finance and operating lease arrangements. Leases in which Alcon transfers substantially all the risks and rewards incidental to ownership to the customer are treated as finance lease arrangements. Revenue from finance lease arrangements is recognized at amounts equal to the fair value of the equipment, which approximates the present value of the minimum lease payments under the arrangements. As interest rates embedded in lease arrangements are approximately market rates, revenue under finance lease arrangements is comparable to revenue for outright sales. Finance income for arrangements longer than twelve months is deferred and subsequently recognized based on a pattern that approximates the use of the effective interest method and recorded in "Other income". Operating lease revenue for equipment rentals is recognized on a straight-line basis over the lease term in "Net sales to third parties".
The consideration Alcon receives in exchange for its goods or services may be fixed or variable. Variable consideration is only recognized when it is highly probable that a significant reversal of cumulative sales will not occur. The most common elements of variable consideration are listed below:
Rebates and discounts granted to government agencies, wholesalers, retail pharmacies, managed health-care organizations and other customers, estimated payments for Medicare Part D prescription drug program coverage gap (commonly called the "donut hole"), patient co-pay program coupon utilization, as well as chargebacks are provisioned and recorded as a deduction from revenue at the time the related revenues are recorded or when the incentives are offered. They are calculated based on historical experience, regulations, the specific terms in the individual agreements, product pricing, channels and payors.
Cash discounts are offered to customers to encourage prompt payment and are provisioned and recorded as revenue deductions at the time the related sales are recorded.
Sales returns provisions are recognized and recorded as revenue deductions when there is historical experience of Alcon agreeing to customer returns and Alcon can reasonably estimate expected future returns. In doing so, the estimated rate of return is applied, determined based on historical experience of customer returns and considering any other relevant factors. This is applied to the amounts invoiced, also considering the amount of returned products to be destroyed versus products that can be placed back in inventory for resale. Where shipments are made on a re-sale or return basis, without sufficient historical experience for estimating sales returns, revenue is only recorded when there is evidence of consumption or when the right of return has expired.
Provisions for revenue deductions are adjusted to actual amounts as rebates, discounts, chargebacks, payment for Medicare Part D prescription drug program, patient co-pay program coupon utilization and returns are processed. The provision represents estimates of the related obligations, requiring the use of judgment when estimating the effect of these sales deductions.
Other revenues
"Other revenues" include revenue from contract manufacturing services which are recognized over time as the service obligations are completed and third party royalty income. Associated costs for contract manufacturing services are recognized in "Cost of other revenues".
Research & development
Internal research & development ("R&D") costs are fully charged to "Research & development" in the Consolidated Income Statement in the period in which they are incurred. Alcon considers that regulatory and other uncertainties inherent in the development of new products preclude the capitalization of internal development expenses as an intangible asset until marketing approval from a regulatory authority is obtained in a major market such as the United States, the European Union, Switzerland, China or Japan.
Payments made to third parties to in-license or acquire intellectual property rights and products, including initial upfront and subsequent milestone payments, are capitalized as intangible assets. If additional payments are made to the originator company to continue to perform R&D activities, an evaluation is made as to the nature of the payments. Such additional payments will be expensed if they are deemed to be compensation for subcontracted R&D services not resulting in an additional transfer of intellectual property rights to Alcon. Such additional payments will be capitalized if they are deemed to be compensation for the transfer to Alcon of additional intellectual property developed at the risk of the originator company. Subsequent internal R&D costs in relation to IPR&D and other assets are expensed until such time
that technical feasibility can be proven, as demonstrated by the receipt of marketing approval for the related product from a regulatory authority in a major market.
Equity-based compensation
Each of the periods presented include expense related to incentive compensation provided to eligible Alcon associates in the form of equity-settled or equity-based awards including restricted stock units ("RSUs") and performance stock units ("PSUs").
Alcon expenses the fair values of RSUs and PSUs granted to associates as compensation over the related vesting periods within the various functions where the associates are employed. The fair values of the awards are determined on their grant dates and are adjusted to account for the specific provisions of each of the corresponding grant agreements.
Alcon RSUs do not entitle the recipients to dividends. As such, the fair value upon grant is based on the Alcon share price at the grant date adjusted for potential future dividends to be paid within the holding period. The fair value of these grants, after making adjustments for assumptions related to their forfeiture during the vesting period, is expensed on a straight-line basis over the respective vesting period.
PSUs are subject to certain performance criteria being achieved during the vesting period and require plan participants to provide services during the vesting period. PSUs granted under Alcon's plans are subject to performance criteria based on internal performance metrics. The expense is determined taking into account assumptions concerning performance during the period relative to targets and expected forfeitures due to plan participants not meeting their service conditions. These assumptions are periodically adjusted. Any change in estimates for past services is recorded immediately as an expense or income in the Consolidated Income Statement and amounts for future periods are expensed over the remaining vesting period. As a result, at the end of the vesting period, the total charge during the whole vesting period represents the amount that will finally vest. The number of equity instruments that finally vest is determined at the vesting date.
If a plan participant leaves Alcon for reasons other than retirement, disability or death, then unvested restricted shares, RSUs and PSUs are forfeited, unless determined otherwise by the provision of the plan rules or by the Compensation Committee of the Company's Board of Directors, for example, in connection with a reorganization.
Restructuring charges
Restructuring provisions are recognized for the direct expenditures arising from the restructuring, where the plans are sufficiently detailed and where appropriate communication to those affected has been made.
Charges to increase restructuring provisions are included in "Other expense" in the Consolidated Income Statement. Corresponding releases are recorded in "Other income" in the Consolidated Income Statement.
Taxes
Taxes on income are expensed in the same periods as the revenues and expenses to which they relate and include any interest and penalties incurred during the period. Deferred taxes are determined using the comprehensive liability method and are calculated on the temporary differences that arise between the tax basis of an asset or liability and its carrying value in the balance sheet prepared for purposes of these Consolidated Financial Statements, except for those temporary differences related to investments in subsidiaries where the timing of their reversal can be controlled and it is probable that the difference will not reverse in the foreseeable future. Alcon recognizes deferred taxes for a new temporary difference where there are previously unrecognized temporary differences, instead of adjusting the amount of those unrecognized differences, for changes in the underlying economics where the initial recognition exemption applies. Since the retained earnings are reinvested, withholding or other taxes on eventual distribution of a subsidiary's retained earnings are only taken into account when a dividend has been planned.
The estimated amounts for current and deferred tax assets or liabilities, including any amounts related to any uncertain tax positions, are based on currently known facts and circumstances. Tax returns are based on an interpretation of tax laws and regulations and reflect estimates based on these judgments and interpretations. The tax returns are subject to examination by the competent taxing authorities which may result in an assessment being made requiring payments of additional tax, interest or penalties. Inherent uncertainties exist in the estimates of the tax positions.
The Organization for Economic Cooperation and Development (“OECD") has published Global Anti-Base Erosion (“GloBE”) Model Rules, which include a minimum 15% tax rate by jurisdiction ("Pillar Two"). For the period ended December 31, 2023, we have applied the IASB amendment to IAS 12, Income Taxes, which provides a mandatory temporary exception from recognizing or disclosing deferred taxes related to Pillar Two.
Earnings per share
Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding.
New standards and interpretations not yet adopted
Effective January 1, 2024, Alcon will adopt Amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, to clarify the criteria used in determining the classification on the balance sheet of a liability as non-current where an entity has the right to postpone settlement of the liability for at least twelve months after the reporting date. Adoption of the amendment will have an impact on the classification of certain of Alcon's financial debts currently classified as current due to Alcon's expectation to settle the liabilities within twelve months of the balance sheet date, even though Alcon has the right to roll over the financial debts for at least twelve months after the reporting date.
As of December 31, 2023, the current financial debts balance includes $82 million of financial debts that Alcon has a right to roll over for at least twelve months after balance sheet date that will be reclassified to non-current financial debts upon adoption of the Amendments to IAS 1.
Other than previously described, there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.

Vision Care - Acquisition of Aerie Pharmaceuticals, Inc.
On November 21, 2022, Alcon acquired 100% of the outstanding shares and equity of Aerie Pharmaceuticals, Inc. ("Aerie"), a pharmaceutical company focused on the discovery, development, manufacturing and commercialization of first-in-class ophthalmic therapies. Pursuant to the terms of the Agreement and Plan of Merger, Alcon paid $15.25 per share to acquire all outstanding shares of Aerie's common stock. The total purchase consideration amounted to $744 million and total cash paid for the net identifiable assets recognized, net of cash acquired, was $666 million. Alcon also assumed debt of $316 million. This transaction was accounted for as a business combination that resulted in goodwill of $65 million under the preliminary purchase price allocation ("PPA") of the fair values of the acquired assets and assumed liabilities. The total purchase consideration was funded with proceeds from a bridge loan facility agreement (the "2022 Bridge Loan Facility") on November 21, 2022. Refer to Note 16 for additional information regarding the 2022 Bridge Loan Facility. The PPA was subsequently finalized during the third quarter of 2023, resulting in adjusted goodwill of $21 million. Refer to Note 21.1 for additional information regarding the final PPA.
Series 2032 Notes and Series 2052 Notes issuance
On December 6, 2022, Alcon, through its wholly owned subsidiary Alcon Finance Corporation (“AFC”), completed a private offering of non-current financial debt consisting of $700 million of 5.375% senior notes due 2032 and $600 million of 5.750% senior notes due 2052. The funds borrowed through the issuance, together with cash, were used to repay the remaining $640 million Facility B term loan and the $775 million 2022 Bridge Loan Facility. Refer to Note 16 for additional information.
Vision Care - Acquisition of Eysuvis and Inveltys products
On July 8, 2022, Alcon acquired two pharmaceutical ophthalmic eye drops, Eysuvis and Inveltys, from Kala Pharmaceuticals, Inc. The acquisition complements Alcon’s existing portfolio in the large and fast-growing dry eye category. Pursuant to the terms of the Asset Purchase Agreement, Alcon paid total upfront consideration of $60 million for Eysuvis and Inveltys, paid an additional amount to purchase certain related inventory and assumed certain liabilities of approximately $14 million for a purchase consideration of $79 million. In addition, Alcon agreed to potentially pay additional amounts upon achievement of certain commercial milestones if annual sales exceed defined targets that expire after 2029. The purchase consideration was allocated using the relative fair value approach primarily to currently marketed product intangible assets within the Vision Care reportable segment of $71 million and assumed liabilities of $14 million.
Series 2028 Notes issuance
On May 31, 2022, Alcon, through its wholly owned subsidiary Alcon Finance B.V. (“AFBV”), completed a public offering of $537 million (EUR500 million) of non-current EUR denominated financial debt consisting of 2.375% senior notes due 2028. The funds borrowed through the issuance were used to repay the $376 million (EUR350 million) Facility C term loan in full and partially repay $160 million of the Facility B term loan. Refer to Note 16 for additional information.
Surgical - Acquisition of Ivantis, Inc.
On January 7, 2022, Alcon acquired 100% of the outstanding shares and equity of Ivantis, Inc., a privately-held, US-based company and manufacturer of the Hydrus Microstent, a minimally-invasive glaucoma surgery (“MIGS”) device designed to lower intraocular pressure for open-angle glaucoma patients, for total upfront consideration of $479 million and additional amounts to be potentially paid upon achievement of development and commercial milestones. The acquisition expands Alcon’s surgical portfolio and is expected to help provide a platform for more growth in the glaucoma space. Refer to Note 21.2 for additional information regarding this transaction which was accounted for as an asset acquisition.
Significant transactions in 2021
Vision Care - Acquisition of Simbrinza US commercialization rights
On April 28, 2021, Alcon executed an Asset Purchase Agreement (“Agreement”) to acquire exclusive US commercialization rights to a pharmaceutical ophthalmic eye drop, Simbrinza (brinzolamide/brimonidine tartrate ophthalmic suspension) 1%/0.2%, from Novartis. Under the terms of the Agreement, Alcon paid $355 million at closing on June 8, 2021 and recognized the intangible asset acquisition as currently marketed products within the Vision Care reportable segment. After closing, Alcon and Novartis immediately began a transition period during which Novartis sold Simbrinza on Alcon's behalf. The transition period concluded during the third quarter of 2021 and Alcon began to fully commercialize Simbrinza for the US market. Novartis retains all rights to Simbrinza® outside of the US.

Operating Segments [Abstract]  
Segment information Segment information
The segment information disclosed in these Consolidated Financial Statements reflects historical results consistent with the identifiable reportable segments of Alcon and financial information that the Chief Operating Decision Maker ("CODM") reviews to evaluate segmental performance and allocate resources among the segments. The CODM is the Executive Committee of Alcon.
The businesses of Alcon are divided operationally on a worldwide basis into two identified reportable segments, Surgical and Vision Care. Alcon's reportable segments are the same as its operating segments as Alcon does not aggregate any operating segments in arriving at its reportable segments. As indicated below, certain income and expenses are not allocated to segments.
Reportable segments are presented in a manner consistent with the internal reporting to the CODM. The reportable segments are managed separately due to their distinct needs and activities for research, development, manufacturing, distribution and commercial execution.
The Executive Committee of Alcon is responsible for allocating resources and assessing the performance of the reportable segments.
In Surgical, Alcon researches, develops, manufactures, distributes and sells ophthalmic products for cataract surgery, vitreoretinal surgery, refractive laser surgery and glaucoma surgery. The surgical portfolio also includes implantables, consumables and surgical equipment required for these procedures and supports the end-to-end procedure needs of the ophthalmic surgeon.
In Vision Care, Alcon researches, develops, manufactures, distributes and sells daily disposable, reusable, and color-enhancing contact lenses and a comprehensive portfolio of ocular health products, including products for dry eye, glaucoma, contact lens care and ocular allergies, as well as ocular vitamins and redness relievers.
Alcon also provides services, training, education and technical support for both the Surgical and Vision Care businesses.
The basis of preparation and the selected accounting policies mentioned in Note 2 are used in the reporting of segment results.
The Executive Committee of Alcon evaluates segmental performance and allocates resources among the segments primarily based on net sales and segment contribution.
Net identifiable assets are not assigned to the segments in the internal reporting to the CODM, and are not considered in evaluating the performance of the business segments by the Executive Committee of Alcon.
Segment contribution excludes amortization and impairment charges for acquired product rights or other intangibles, general and administrative expenses for corporate activities, separation costs, transformation costs, fair value adjustments to contingent consideration liabilities, past service costs primarily for post-employment benefit plan amendments, acquisition and integration related costs, certain acquisition related items and certain other income and expense items.
General & administration (corporate) includes the costs of the Alcon corporate headquarters, including all related corporate function costs.
Other income and expense items excluded from segment contribution include fair value adjustments of financial assets in the form of options to acquire a company carried at FVPL, net gains and losses on fund investments and equity securities valued at FVPL, restructuring costs, legal provisions and settlements and other income and expense items not attributed to a specific segment.

Analysis of tax rate
Alcon's overall applicable tax rate can change each year since it is calculated as the weighted average tax rate based on pre-tax income/(loss) of each subsidiary. The main elements contributing to the difference between Alcon's overall applicable tax rate and the effective tax rate are summarized in the below table.

(2)Includes agreements for fiscal years 2023, 2022 and 2021. 2023 also includes a long-term Swiss Tax Agreement; however, it is uncertain whether Alcon will obtain a similar treatment for future years for a portion of the benefit.
(3)Primarily includes the net effect of partial reserves and benefits recognized for the deductibility of statutory expenses in Switzerland. 2023 also includes the release of reserves in US and Germany following the conclusion of tax audits and other items. 2021 also relates to international transfer pricing.
Alcon has a substantial business presence in many countries and is therefore subject to different income and expense items that are non-taxable (permanent differences) or are taxed at different rates in those tax jurisdictions. This results in a difference between Alcon's applicable tax rate and effective tax rate as shown in the table above.
Fluctuations in taxes and effective tax rates are primarily due to the geographical pre-tax income and loss mix across certain tax jurisdictions relative to Alcon's consolidated income before taxes, changes in uncertain tax positions and certain non-recurring items.
The applicable tax rate was 20.2% in 2023, compared to 22.5% in 2022, primarily due to the mix of pre-tax income/(loss) across geographical jurisdictions. The effective tax rate was a 17.1% benefit in 2023, compared to 27.6% expense in 2022. The current year was primarily driven by a $263 million net benefit associated with the 2023 Swiss Tax Agreement (as defined below) and a net benefit of $36 million from other discrete tax items. The prior year expense was primarily driven by the 2022 APA (as defined below), partially offset by favorable discrete tax items.
The increase in the applicable tax rate for 2022 compared to 9.3% in 2021 was primarily driven by more profit being taxable at the rate applicable in the US compared to Alcon's historical filing position as a result of the 2022 APA. The applicable tax rate in 2021 was impacted by pre-tax losses in certain tax jurisdictions.
Tax returns are subject to examination by competent taxing authorities, which may result in assessments being made requiring payments of additional tax, interest or penalties. Inherent uncertainties exist in the estimates of the tax positions.
2023 Swiss Tax Agreement
During the fourth quarter of 2023, Alcon entered into a long-term agreement with Switzerland tax authorities related to the deductibility of a statutory expense in Switzerland through March 31, 2039 (the "2023 Swiss Tax Agreement"). Alcon recorded a discrete tax benefit of $263 million in "Taxes" in the Consolidated Income Statement and corresponding deferred tax asset, net of reserves.
2022 Advanced Pricing Agreement
During the fourth quarter of 2022, Alcon recognized the impact of an Advanced Pricing Agreement between US and Switzerland tax authorities (the "2022 APA") related to the allocation and taxation of relevant Alcon profits between the US and Switzerland retroactive to 2019. The 2022 APA results in more profit being taxable at the rate applicable in the US compared to Alcon’s historical filing position. As a result, in the fourth quarter of 2022 Alcon recorded a discrete item of $37 million of income tax expense related to the 2019 through 2021 tax years and an increase of $64 million of income tax expense for the year ended December 31, 2022. The 2022 APA was agreed upon in the first quarter of 2023 and is valid through 2027.
Pillar Two income taxes
The OECD has published GloBE Model Rules, which include a minimum 15% tax rate by jurisdiction ("Pillar Two"). Various countries have enacted or intend to enact tax legislation to comply with Pillar Two rules. Alcon is within the scope of the OECD’s Pillar Two, which did not impact 2023 results but will impact Alcon’s financial results from January 1, 2024 onward.
Of the countries enacting Pillar Two legislation, we expect Switzerland to be the most impactful to Alcon. In December 2023, the Swiss government decided to partially implement Pillar Two by introducing a Qualified Domestic Minimum Top-up Tax (“QDMTT”) to reach the required taxation level of 15% on Pillar Two qualifying profits earned by companies domiciled in Switzerland effective from January 1, 2024. This QDMTT will not be applied to the Pillar Two qualifying profits earned by subsidiaries domiciled in tax jurisdictions outside of Switzerland. The implementation timing and specific provisions of any further Pillar Two tax regulations in Switzerland remain subject to further assessments at both the Federal and Cantonal levels. For the period ended December 31, 2023, we have applied the IASB amendment to IAS 12, Income Taxes, which provides a mandatory temporary exception from recognizing or disclosing deferred taxes related to Pillar Two such that there is no impact to the 2023 Consolidated Financial Statements. The future impact of Pillar Two for Alcon is estimated to increase Alcon's effective tax rate by approximately 1% to 2%. We are continuing to follow Pillar Two legislative developments to evaluate the potential future impact on our consolidated results of operations, financial position and cash flows beginning in 2024.

All of the Company's 6.4 million shares held in treasury as of December 31, 2023 may only be used to fulfill the future vesting of existing and future equity-based awards.
Capital range and conditional share capital
On May 5, 2023, Alcon's shareholders approved the introduction of a capital range and a conditional share capital in Alcon's Articles of Incorporation. Under the capital range, and until May 5, 2028 or an earlier expiry, the Company's Board of Directors (the "Board") has the authority to increase or decrease the share capital ranging from CHF 19 million (lower limit) to CHF 22 million (upper limit). The capital increase or decrease may be effected by (A) issuing up to the lower of (i) 50 million fully paid-in registered shares and (ii) 10% of the share capital at the time of increase or (B) cancelling up to 25 million registered shares, as applicable. The Board is further authorized to withdraw or restrict subscription rights of existing shareholders and allocate such rights to third parties, the Company or any of its group companies, for the purposes of (a) raising equity capital, (b) acquisition transactions, (c) broadening the shareholders constituency in certain financial or investor market or (d) Board, executive management, employees, advisors or other participation programs.
The Board can also rely on a conditional share capital instrument in its Articles of Incorporation through which the share capital may be increased in an amount not to exceed CHF 2.0 million, by the issuance of up to 50 million fully paid-in registered shares through the voluntary or mandatory exercise of conversion, exchange, option, warrant, subscription or other rights granted to or imposed on shareholders or third parties alone or in connection with the issuance of bonds, notes, options, warrants or other similar securities or contractual obligations of the Company or its affiliates. The conditional share capital may be used for the same purposes as stated in the preceding paragraph in connection with the capital range. As of December 31, 2023, the Board had not made use of the authority under any of the capital range or conditional share capital provisions.
7.2 Dividends
On February 27, 2023, the Board proposed a dividend of CHF 0.21 per share, which was subsequently approved by the shareholders at the Annual General Meeting on May 5, 2023 and paid in May 2023 for an amount of $116 million.
On February 15, 2022, the Board proposed a dividend of CHF 0.20 per share, which was subsequently approved by the shareholders at the Annual General Meeting on April 27, 2022 and paid in May 2022 for an amount of $100 million.
On February 23, 2021, the Board proposed a dividend of CHF 0.10 per share, which was subsequently approved by the shareholders at the Annual General Meeting on April 28, 2021 and paid in May 2021 for an amount of $54 million.    
7.3 Earnings per share
Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding during the period. For the years ended December 31, 2023, 2022 and 2021, the weighted average number of shares outstanding was 493.0 million, 491.4 million and 490.0 million shares, respectively.
The only potentially dilutive securities are the outstanding unvested equity-based awards under the Company's equity-based incentive plans, as described in Note 23. Except when the effect would be anti-dilutive, the calculation of diluted earnings per common share includes the weighted average net impact of unvested equity-based awards. For the years ended December 31, 2023, 2022 and 2021, the weighted average diluted number of shares outstanding was 496.5 million, 494.4 million and 493.4 million, respectively, which includes the potential conversion of 3.5 million, 3.0 million and 3.4 million unvested equity-based awards, respectively.
The average market value of the Company's shares for the purposes of calculating the potentially dilutive effects of unvested equity-based awards was based on quoted market prices for the period that the unvested awards were outstanding.

The Surgical and Vision Care reportable segments' CGUs, to which goodwill is allocated, are comprised of a group of smaller CGUs. The valuation method of the recoverable amount of the CGUs, to which goodwill is allocated, is based on the FVLCOD.
The Alcon brand name is an intangible asset with an indefinite life. The intangible asset is not allocated to the reportable segments as it is used to market the Alcon-branded products of both the Surgical and Vision Care businesses. Net sales of these products together are the grouping of CGUs, which is used to determine the recoverable amount. The valuation method is based on the FVLCOD.
The following assumptions were used in the calculations for the recoverable amounts of goodwill and the Alcon brand name at December 31, 2023 and 2022:
(As a percentage)SurgicalVision Care
Terminal growth rate3.0 3.0 
Discount rate (post-tax)9.0 8.75 
The Surgical and Vision Care reportable segments' terminal growth rate assumption of 3.0% takes into consideration how the industry is expected to grow, analysis of industry expert reports, and expected relevant changes in demographics for various markets. The discount rates for both Surgical and Vision Care reportable segments consider Alcon's weighted average cost of capital, adjusted to approximate the weighted average cost of capital of comparable market participants. Both the terminal growth rates and the discount rates are consistent with external sources of information.
The FVLCOD, for all groupings of CGUs containing goodwill or indefinite life intangible assets, is reviewed for the impact of reasonably possible changes in key assumptions. In particular Alcon considered an increase in the discount rate, a decrease in the terminal growth rate and certain negative impacts on the forecasted cash flows. These reasonably possible changes in key assumptions did not indicate an impairment.
Refer to "Impairment of goodwill, Alcon brand name and definite lived intangible assets" and "Acquired In-Process Research & Development ("IPR&D")" in Note 2 for additional disclosures on how Alcon performs goodwill and intangible asset impairment testing.

For the year ended December 31, 2022, impairment charges recognized in the Consolidated Income Statement amounted to $62 million, primarily due to impairments of $61 million recognized in the second quarter. An impairment charge of $59 million was recognized in Cost of net sales for a currently marketed product CGU in the Surgical reportable segment due to higher forecasted research and development costs associated with product redesign and delayed launch date of the next generation product. The CGU was reduced to its recoverable amount of $15 million determined based on the VIU method at the time of impairment. VIU was estimated using net present value techniques utilizing pre-tax cash flows and a discount rate of 7.8%. The remaining impairment charge of $2 million in the second quarter was recognized in Research & development to fully impair an acquired research & development intangible asset in the Vision Care reportable segment which will no longer be used.
For the year ended December 31, 2021, impairment charges recognized in the Consolidated Income Statement amounted to $225 million. Impairments of $180 million were recognized in Research & development in 2021. Of that amount, an impairment charge of $178 million was recognized in the third quarter of 2021 in Research & development to fully impair a CGU in the Surgical reportable segment upon a decision to suspend research and development efforts and commercialization of the product as Alcon prioritizes other products in the portfolio. An additional impairment charge of $2 million was recognized in the fourth quarter of 2021 in Research & development to fully impair a licensed technology in the Vision Care reportable segment, which will no longer be used in any future research and development activities. The remaining amount of $45 million relates to an impairment charge recognized in the first quarter of 2021 in Cost of net sales for a currently marketed product CGU in the Vision Care reportable segment due to lower expected sales. The CGU was reduced to its recoverable amount of $48 million determined based on the FVLCOD method at the time of impairment. FVLCOD was estimated using net present value techniques utilizing post-tax cash flows and a discount rate as there are no direct or indirect observable prices in active markets for identical or similar assets. The discount rate was consistent with the rate used in the annual goodwill impairment assessment.
The estimates used in calculating net present values involve significant judgement by management and include assumptions with measurement uncertainty. The estimates include cash flow projections for a five-year period based on management forecasts, sales forecasts beyond the five-year period extrapolated using long-term expected growth rates, discount rates and future tax rates. Actual cash flows and values could vary significantly from forecasted future cash flows and related values derived using net present value techniques.
For FVLCOD, the estimates used are considered to be consistent with market participant assumptions. Since the cash flow projections are a significant unobservable input, the fair value of the CGUs were classified as Level 3 in the fair value hierarchy.

For foreign unremitted earnings retained by consolidated entities for reinvestment, which amounted to $9 billion as of December 31, 2023 and December 31, 2022, no provision is made for income taxes that would be payable upon the distribution of these earnings. If these earnings were remitted, an income tax charge could result based on the tax statutes currently in effect.
IFRS exceptions to recognizing taxable temporary differences include an exception to recognizing a deferred tax liability arising on the initial recognition of goodwill from acquisitions. As such, we have not provided a deferred tax for goodwill from acquisitions which amounted to $8.9 billion as of December 31, 2023 and 2022.
The gross value of capital loss carryforwards for which no deferred tax assets were recognized amounted to $131 million at December 31, 2023 ($120 million at December 31, 2022), most of which will expire in three years.
Tax loss carryforwards are capitalized as deferred tax assets to the extent it is probable that sufficient taxable income will be available for the foreseeable future.

Trade receivables Trade receivables
Trade receivable balances include sales to wholesalers, retailers, doctor groups, private health systems, government agencies, pharmacy benefit managers, managed health-care organizations and government-supported healthcare systems. We closely monitor the level of trade receivables in the countries deemed to have an elevated credit risk. We consider macroeconomic and geopolitical environment, country profile and historical experience in addition to other relevant information when assessing the credit risk. Deteriorating credit risk factors may result in an increase in the average length of time that it takes to collect these trade receivables and may require Alcon to reevaluate the expected credit loss amount of these trade receivables in future periods or change the terms on which we operate. As of December 31, 2023, the amounts past due for more than one year in elevated credit risk countries are not significant.
The following tables provide details related to Trade receivables as of December 31, 2023 and 2022, including trade receivables that are not overdue as specified in the payment terms and conditions established with Alcon's customers, as well as an analysis of overdue amounts, expected credit loss rates and related provisions for doubtful trade receivables:

Series 2028 Notes issuance
On May 31, 2022, AFBV issued EUR denominated senior notes due in 2028 ("Series 2028 Notes"). The Series 2028 Notes are unsecured senior obligations of AFBV issued and closed in a public offering and rank equally in right of payment with the Series 2026, Series 2029, Series 2030 and Series 2049 notes. The total principal of the Series 2028 Notes is $553 million
(EUR500 million) as of December 31, 2023. The Series 2028 Notes were issued at 99.476% with 2.375% interest payable annually in May, beginning in May 2023. The Series 2028 Notes were issued at a discount totaling $3 million, which was recorded as a reduction to the carrying value of the Series 2028 Notes and will be amortized to Interest expense over the term of the Series 2028 Notes. AFBV incurred $3 million of debt issuance costs, which were recorded as a reduction to the carrying value of the Series 2028 Notes and will be amortized to Other financial income & expense over the term of the Series 2028 Notes.
On May 31, 2022, the funds borrowed through the issuance of the Series 2028 Notes were used to fully repay the $376 million (EUR350 million) Facility C term loan maturing in 2024 and repay $160 million of the $800 million Facility B term loan maturing in 2024. The transactions were accounted for as an extinguishment and partial extinguishment of a liability, respectively. Alcon recognized losses on extinguishment of $1 million associated with the write-off of unamortized deferred financing costs in Other financial income & expense during the second quarter of 2022.
2022 Bridge Loan Facility
On September 14, 2022, AFC executed a $900 million 2022 Bridge Loan Facility with J.P. Morgan Chase Bank, N.A. London Branch. The 2022 Bridge Loan Facility was fully guaranteed by the Company and was restricted for use in funding the acquisition of Aerie. On September 27, 2022, a Syndication Agreement was executed to add more financial institutions as new lenders, effective from September 28, 2022.
On November 21, 2022, in connection with the consummation of the Aerie acquisition, $775 million of the financing commitments were drawn with net proceeds of $771 million used for the acquisition of Aerie. AFC incurred $4 million of debt issuance costs, which were recorded as a reduction to the carrying value of the 2022 Bridge Loan Facility.
Series 2032 Notes and Series 2052 Notes issuance
On December 6, 2022, AFC issued senior notes due in 2032 ("Series 2032 Notes") and 2052 ("Series 2052 Notes"). The Series 2032 Notes and Series 2052 Notes are unsecured senior obligations of AFC issued and closed in a private offering and rank equally in right of payment with the Series 2026, Series 2028, Series 2029, Series 2030 and Series 2049 notes. The principal amounts of the Series 2032 Notes and Series 2052 Notes are $700 million and $600 million, respectively. The Series 2032 Notes and Series 2052 Notes were issued at a discount of $4 million and $2 million, respectively, which were recorded as a reduction to the carrying values of the Series 2032 Notes and Series 2052 Notes and will be amortized to Interest expense over the term of the notes. AFC incurred debt issuance costs of $4 million and $7 million for the Series 2032 Notes and Series 2052 Notes, respectively, which were recorded as a reduction to the carrying values of the Series 2032 Notes and Series 2052 Notes and will be amortized to Other financial income & expense over the term of the notes.
The Notes consist of the following:
•     Series 2032 Notes - $700 million due in 2032 issued at 99.458%, 5.375% interest is payable twice per year in December and June, beginning in June 2023.
•     Series 2052 Notes - $600 million due in 2052 issued at 99.674%, 5.750% interest is payable twice per year in December and June, beginning in June 2023.
Using the funds borrowed through the issuance of the Series 2032 Notes and Series 2052 Notes together with cash, the Company exercised its early redemption rights to fully repay the remaining $640 million Facility B term loan and to fully repay the drawn amount of $775 million under the 2022 Bridge Loan Facility, as required by the mandatory prepayment clause. Consequently, the undrawn commitment of the 2022 Bridge Loan Facility was cancelled. The transactions were accounted for as extinguishment of liabilities. Alcon recognized losses on extinguishment of $4 million associated with the write-off of unamortized deferred financing costs in Other financial income & expense during the fourth quarter of 2022.
Senior notes assumed in Aerie acquisition
As part of the Aerie acquisition, Alcon assumed Aerie's $316.2 million convertible senior notes due on October 1, 2024. The convertible notes were issued at 1.500% interest payable semi-annually on April 1 and October 1 of each year. Following the delisting of Aerie on November 21, 2022, the senior notes were no longer convertible to equity. On December 20, 2022, Alcon made payments of $316.0 million to note holders. As of December 31, 2023, $0.2 million remained outstanding.
Series 2030 Notes issuance
On May 27, 2020, AFC issued senior notes due in 2030 (“Series 2030 Notes”). The Series 2030 Notes are unsecured senior obligations of AFC issued in a private placement and rank equally in right of payment with the Series 2026, Series 2029,
and Series 2049 notes. The total principal amount of the Senior 2030 Notes is $750 million. The Senior 2030 Notes were issued at 99.843% with 2.600% interest payable twice per year in May and November, beginning in November 2020. The Series 2030 Notes were issued at a discount totaling $1 million, which was recorded as a reduction to the carrying value of the Series 2030 Notes and will be amortized to Interest expense over the term of the Series 2030 Notes. AFC incurred $5 million of debt issuance costs, which were recorded as a reduction to the carrying value of the Series 2030 Notes and will be amortized to Other financial income & expense over the term of the Series 2030 Notes.
Revolving Credit Facility
On October 27, 2023, the Company and certain of its subsidiaries and a group of commercial banks entered into a refinancing agreement to replace the $1.0 billion unsecured committed multicurrency revolving credit facility maturing in March 2026. The new agreement consists of a $1.32 billion unsecured committed multicurrency revolving credit facility now maturing five years after the date of the agreement (the “Refinanced Revolving Facility Agreement”). The Refinanced Revolving Facility Agreement primarily bears interest rates equal to a term reference rate or a compounded reference rate, depending on currency, plus an applicable margin and a term reference rate credit adjustment spread, if applicable. It also includes relevant fallback mechanisms in case of rate unavailability. The Revolving Credit Facility remained undrawn as of December 31, 2023.
Local bilateral facilities
Alcon holds a number of local bilateral facilities in different countries with the largest share of borrowings in Japan. During the year ended December 31, 2022, changes in financial debts for local bilateral facilities primarily included the movement of balances from non-current to current and payment of certain local bilateral facilities in Japan. In addition, one local bilateral facility in Japan matured in February 2022 and was renewed for another one year term.
On February 14, 2023, three local bilateral facilities in Japan which matured in February 2023 were refinanced by three facilities with two year maturities. As of December 31, 2023, $82 million of the drawn local facilities balance was classified as current due to Alcon's expectation to settle the liabilities within twelve months of the balance sheet date. There was $49 million undrawn on the facilities in Japan as of December 31, 2023.

(1) The carrying amount is a reasonable approximation of fair value, with the exception of the Series 2026, 2028, 2029, 2030, 2032, 2049 and 2052 Notes recorded in Non-current financial debts with a fair value of $4,347 million and carrying value of $4,566 million as of December 31, 2023 and a fair value of $4,145 million and carrying value of $4,541 million as of December 31, 2022. The fair value of notes was determined using Level 2 inputs. The notes were valued using a quoted market price for such notes, which have low trading volumes.
Fair value by hierarchy
As required by IFRS, financial assets and liabilities recorded at fair value in the Consolidated Financial Statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. There are three hierarchical levels, based on an increasing amount of judgment associated with the inputs to derive fair value for these financial assets and liabilities, which are as follows:
Financial assets and liabilities carried at Level 1 fair value hierarchy are listed in active markets.
Financial assets and liabilities carried at Level 2 fair value hierarchy are valued using corroborated market data.
Level 1 financial assets include money market funds and deferred compensation assets. There were no financial liabilities carried at Level 1 fair value, and Level 2 financial assets and liabilities include derivative financial instruments.
Investments in money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The investments are classified as Cash & cash equivalents within the Consolidated Balance Sheet.
Deferred compensation investments for certain employee benefit plans are held in a rabbi trust and dedicated to pay the benefits under the associated plans but are not considered plan assets as the assets remain available to creditors of Alcon in certain events, including bankruptcy. Rabbi trust assets primarily consist of investments in mutual funds. These assets are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.
Level 3 inputs are unobservable for the financial asset or liability. The financial assets and liabilities generally included in the Level 3 fair value hierarchy are equity securities and convertible notes receivable of private companies measured at FVOCI, fund investments, options to acquire private companies, and contingent consideration liabilities measured at FVPL.
The following tables summarize financial assets and liabilities measured at fair value on a recurring basis or at amortized cost or cost as of December 31, 2023 and December 31, 2022.

Long-term note receivable and other financial assets measured at amortized cost
On May 22, 2023, Alcon entered into financing arrangements with a long-term supplier, Lifecore Biomedical, Inc. and certain of its affiliates (collectively, “Lifecore”). Alcon provided Lifecore total commitments of $150 million, primarily related to a $142 million senior term loan facility ("Long-term note receivable") maturing on May 22, 2029. The arrangements also include a sale and leaseback agreement for certain machinery and equipment. Transaction costs directly attributable to the acquisition of the financial assets amounting to $4 million were capitalized to financial assets at amortized cost.
The Long-term note receivable bears an annual fixed interest rate of 10%, which is payable in kind (“PIK”) for the first three years, and payable 3% in cash interest and 7% PIK interest thereafter until maturity, unless otherwise elected by Lifecore to pay a greater proportion in cash. The Long-term note receivable is secured by a Pledge and Security agreement (“security agreement”) whereby Alcon is granted first priority security interest in certain collateral, including but not limited to equipment, fixtures, real property and intellectual property. The security agreement is in effect until the payment in full of the term loan facility.
Due to Lifecore's significant financial difficulties at the time the loan was originated, Alcon concluded the financial assets were originated credit-impaired. The lifetime ECL was analyzed at inception and utilized in calculating the credit-adjusted effective interest rate with no impact on the carrying value of the financial assets or effective interest rate of 10%. In addition, as of December 31, 2023, Alcon assessed there was no lifetime ECL due to the assessment of the collateral under the security agreement.

Adjustments for changes in assumptions17 23 
Balance as of December 31(90)(98)
Changes in contingent consideration liabilities in the current year include fair value adjustments for changes in assumptions of $17 million, primarily due to revised expectations for timing of settlement and probability of success for development and commercial milestones. As of December 31, 2023, the probability of success for various development and commercial milestones ranges from 3% to 55% and the maximum remaining potential payments related to contingent consideration from business combinations is $395 million, plus other amounts calculated as a percentage of commercial sales in cases where there is not a specified maximum contractual payment amount. The estimation of probability typically
depends on factors such as technical milestones or market performance and is adjusted for the probability of payment. If material, probable payments are appropriately discounted to reflect the impact of time.
Changes in contingent consideration liabilities in the prior year included fair value adjustments for changes in assumptions of $23 million, primarily due to revised expectations for achievement and timing of settlement for development and commercial milestones. As of December 31, 2022, the probability of success for various development and commercial milestones ranged from 55% to 57% and the maximum remaining potential payments related to contingent consideration from business combinations was $395 million, plus other amounts calculated as a percentage of commercial sales in cases where there is not a specified maximum contractual payment amount.
Contingent consideration liabilities are reported in “Provisions & other non-current liabilities" based on the projected timing of settlement which is estimated to range from 2029 through 2035 for contingent consideration obligations as of December 31, 2023.
For the determination of the fair value of a contingent consideration various unobservable inputs are used. A change in these inputs might result in a significantly higher or lower fair value measurement. The inputs used are, among others, the probability of success, sales forecast and assumptions regarding the discount rate, timing and different scenarios of triggering events. The significance and usage of these inputs to each contingent consideration may vary due to differences in the timing and triggering events for payments or in the nature of the asset related to the contingent consideration.
As the most significant Level 3 input, if the probability of success were to change by 10% positively or negatively, this would change the amount recorded for contingent consideration payables in the 2023 Consolidated Income Statement by $17 million.
Derivatives
As of December 31, 2023, the net value of unsettled positions for derivative forward contracts and swaps was $8 million, including $2 million of unrealized gains in Other current assets and $10 million of unrealized losses in Current financial debts. As of December 31, 2022, the net value of unsettled positions for derivative forward contracts and swaps was $2 million, including $8 million of unrealized gains in Other current assets and $10 million of unrealized losses in Current financial debts. There are master agreements with several banking counterparties for derivatives financial instruments; however, there were no derivative financial instruments meeting the offsetting criteria under IFRS as of December 31, 2023 or December 31, 2022.
Nature and extent of risks arising from financial instruments
Market risk
Alcon is exposed to market risk, primarily related to foreign currency exchange rates, interest rates and the market value of investments of liquid funds. Alcon actively monitors and seeks to reduce, where it deems it appropriate to do so, fluctuations in these exposures. It is Alcon policy and practice to enter into a variety of derivative financial instruments to manage the volatility of these exposures and to enhance the yield on the investment of liquid funds. Alcon does not enter into any financial transactions containing a risk that cannot be quantified at the time the transaction is concluded. In addition, Alcon does not sell short assets it does not have, or does not know it will have, in the future. Alcon only sells existing assets or enters into transactions and future transactions (in the case of anticipatory hedges) that it confidently expects it will have in the future, based on past experience. In the case of liquid funds, Alcon may write call options on assets it has, or write put options on positions it wants to acquire and has the liquidity to acquire. Alcon expects that any loss in value for these instruments generally would be offset by increases in the value of the underlying transactions.
Foreign currency exchange rate risk
Alcon uses the US Dollar as its reporting currency and is therefore exposed to foreign currency exchange movements, primarily in Euros, Japanese Yen, Chinese Renminbi, Canadian Dollars, Korean Won, Swiss Francs, Russian Rubles and emerging market currencies. Fluctuations in the exchange rate between the US Dollar and other currencies can have a significant effect on both Alcon’s results of operations, including reported sales and earnings, as well as on the reported value of Alcon's assets, liabilities and cash flows. This, in turn, may significantly affect the comparability of period-to-period results of operations.
Alcon manages its global currency exposure by engaging in hedging transactions where management deems appropriate (forward contracts and swaps). Specifically, Alcon enters into various contracts that reflect the changes in the value of foreign currency exchange rates to preserve the value of assets. Refer to Note 2 for information regarding the hyperinflationary economies in which Alcon operates.
Interest rate risk
Alcon's exposure to cash flow interest rate risks arises from the portion of financial debts at variable rates. Alcon may enter into interest rate swap agreements, in which it exchanges periodic payments based on a notional amount and agreed-upon fixed and variable rate interests. If the interest rates for financial debts at variable rates had been higher / lower by 1% in 2023, the income before taxes would have been lower / higher by $2 million from the impacts of interest expense based on the change in the interest rate. As of December 31, 2023, 97% of Alcon's financial debt is at fixed interest rates materially reducing future exposure to cash flow interest rate risk.
Commodity price risk
Alcon's exposure to commodity price risk arises from inflation and supply chain challenges related to anticipated purchases of certain commodities used as raw materials by Alcon's businesses. A change in those prices may alter the gross margin of a specific business, but generally not by more than 10% of the gross margin and thus below Alcon's risk management tolerance levels. Alcon primarily manages inflationary pressures through pricing actions and productivity initiatives. Based on historical and anticipated price fluctuations, Alcon does not enter into significant forward and option contracts to manage fluctuations in prices of anticipated purchases.
Credit risk
Credit risks arise from the possibility that customers may not be able to settle their obligations as agreed. To manage this risk, Alcon periodically assesses credit risk, assigns individual credit limits, and takes actions to mitigate credit risk where appropriate. Refer to Note 13 for more information.
No customer accounted for 10% or more of Alcon's net sales in 2023, 2022 or 2021.
Credit risk also arises from originated credit-impaired financial assets (Long-term note receivable and other financial assets at amortized cost). The maximum exposure to credit risk is reflected in the carrying value of the assets, which amounted to $162 million as of December 31, 2023, including a non-current portion of $161 million in "Long-term note receivable and other financial assets measured at amortized cost" in Financial assets and a current portion of $1 million in "Other receivables, security deposits and current assets" in Other current assets. As of December 31, 2023, the credit risk exposure is fully mitigated by the collateral, with an estimated amount of approximately $375 million, in accordance with the terms of the security agreement. In addition, Alcon performs an ongoing credit evaluation of Lifecore’s financial condition, monitors payment performance and assesses current economic conditions, as well as reasonable and supportable forecasts of future economic conditions, that may affect collectability of the outstanding financial assets.
Liquidity risk
Liquidity risk is defined as the risk that Alcon may not be able to settle or meet its obligations on time or at a reasonable price. Alcon Treasury is responsible for liquidity, funding and settlement management. In addition, liquidity and funding risks, and related processes and policies, are overseen by management. Alcon manages its liquidity risk on a consolidated basis according to business needs, tax, capital or regulatory considerations, if applicable, through numerous sources of financing in order to maintain flexibility. Alcon's cash and cash equivalents are maintained at a number of financial institutions. To mitigate the risk of uninsured balances, management selects financial institutions based on their credit ratings and financial strength, and performs ongoing evaluations of these institutions to limit our concentration risk exposure. Management monitors Alcon's net debt or liquidity position through rolling forecasts on the basis of expected cash flows. Refer to Note 16 for further information on maturity of the contractual undiscounted cash flows for Alcon's borrowings and interest on borrowings.

Provisions and other non-current liabilities Provisions and other non-current liabilities
The below table provides details related to Provisions and other non-current liabilities as of December 31, 2023 and 2022:
($ millions)Note20232022
Accrued liability for employee benefits:
Defined benefit pension plans22221 175

Other non-current liabilities76 132 
Total provisions and other non-current liabilities784 786 
Alcon believes that its total provisions are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities in this area, Alcon may incur additional costs beyond the amounts provided. Management believes that such additional amounts, if any, would not be material to Alcon's financial condition but could be material to the results of operations or cash flows in a given period.
Provisions for litigation and other legal matters
Alcon has established provisions for certain litigation and other legal matters, where a potential cash outflow is probable and a reliable estimate can be made of the amount of the outflow. These provisions represent the current best estimate of the total financial effect for these matters. Potential cash outflows reflected in a provision may be fully or partially offset by insurance in certain circumstances.
Alcon has not established provisions for potential damage awards for certain additional legal claims if Alcon currently believes that a payment is either not probable or cannot be reliably estimated. A number of other legal matters are in such early stages or the issues presented are such that Alcon has not made any provisions since it cannot currently estimate either a potential outcome or the amount of any potential losses. For these reasons, among others, Alcon generally is unable to make a reliable estimate of possible loss with respect to such cases. It is therefore not practicable to provide information about the potential financial impact of those cases.
There might also be cases for which Alcon was able to make a reliable estimate of the possible loss or the range of possible loss, but Alcon believes that publication of such information on a case-by-case basis would prejudice Alcon's position in ongoing legal proceedings or in any related settlement discussions. Accordingly, in such cases, information would be disclosed with respect to the nature of the contingency, but no disclosure is provided as to an estimate of the possible loss or range of possible loss.
Note 25 contains additional information on contingencies.
Summary of significant legal proceedings
A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property, including under the Hatch-Waxman Act, and anti-bribery matters such as those under the Foreign Corrupt Practices Act of 1977 ("FCPA"), as amended.
As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow. The following is a summary as of February 27, 2024 of significant legal proceedings to which Alcon or its subsidiaries were or are currently a party.
JJSVI patent dispute
On June 23, 2020, Johnson & Johnson Surgical Vision, Inc. ("JJSVI"), acting through its subsidiaries, filed a patent infringement action in the US District Court in Delaware alleging that the manufacture, use, sale, offer for sale, and/or importation of Alcon’s LenSx Laser System willfully infringes, directly and/or indirectly, one or more claims of 12 US patents. JJSVI subsequently amended its complaint to include copyright infringement claims relating to, among other things, source code used in the LenSx Laser System as well as additional claims of patent infringement. Also beginning on June 23, 2020, JJSVI filed claims in Mannheim, Germany, alleging that Alcon directly infringes certain European patents through its manufacture and sale of LenSx. In these cases, JJSVI sought monetary and injunctive relief. Alcon defended all of these cases vigorously and asserted various patent infringement and invalidity claims against JJSVI in Europe and the US. Prior to the trial on the copyright claims in the Delaware action set for February 2023, the parties entered into a confidential settlement agreement to resolve all of the pending legal proceedings described above. As part of that resolution, the parties exchanged cross-licenses of certain intellectual property and other mutually agreed covenants and releases, and Alcon made a one-time payment to JJSVI of $199 million on April 3, 2023, which was accrued as of December 31, 2022, for those rights and to resolve the parties’ various worldwide intellectual property disputes concerning femtosecond laser-assisted cataract surgery devices. This case is now concluded.
Asia / Russia investigation
In 2017 and 2018, Alcon and Novartis Group companies, as well as certain present and former executives and associates of Alcon and Novartis, received document requests and subpoenas from the US Department of Justice (“DoJ”) and the SEC requesting information concerning Alcon accounting, internal controls and business practices in Asia and Russia, including revenue recognition for surgical equipment and related products and services and relationships with third party distributors, both before and after Alcon became part of the Novartis Group. The investigations by the DoJ and the SEC have concluded. On June 25, 2020, Alcon entered into a three-year Deferred Prosecution Agreement ("DPA") with the DoJ regarding a charge that Alcon Pte Ltd. conspired to falsify financial books and records in violation of the US FCPA. The charge relates to payments made by a former distributor to health care providers in Vietnam between 2007 and 2014. Alcon agreed to pay the DoJ a penalty of $8.925 million, for which Novartis has indemnified Alcon. The DPA expired on June 25, 2023. On December 21, 2023, in accordance with the DPA, the DoJ filed a request with the US District Court for the District of New Jersey to dismiss the criminal charge against Alcon Pte Ltd. with prejudice. On December 21, 2023, the Court issued an order dismissing the charge against Alcon Pte Ltd. with prejudice. This case is now concluded.
Hoya patent dispute
On December 11, 2020, Hoya Corporation and one of its affiliates (collectively, "Hoya") filed suit against Alcon in the US District Court for the Northern District of Texas alleging that Alcon's UltraSert Pre-Loaded Delivery System infringes six of Hoya's US patents. The court denied in part Alcon’s motion to dismiss Hoya’s complaint on September 20, 2021. On December 13, 2023, the court denied Hoya’s motion for summary judgment with respect to Alcon’s defense that Hoya derived the subject matter of the asserted patents from certain Alcon products. On January 11, 2024, the court granted Alcon’s motion for summary judgment of non-infringement with respect to three of the six asserted patents and certain claims of the other three asserted patents, and also granted Alcon’s motion for summary judgment with respect to Hoya’s claim that Alcon’s alleged infringement was willful. This matter was fully and finally resolved prior to the trial scheduled to begin on February 20, 2024.
Hatch-Waxman patent litigation
From time to time, Alcon is a party to certain patent infringement proceedings in the US in connection with Notices of Paragraph IV Certification under the Hatch-Waxman Act received from third-party generic manufacturers respecting their applications for generic versions of certain products sold by or on behalf of Alcon, including Simbrinza, Pataday, Rhopressa and Rocklatan, or other similar suits.
During the third quarter of 2022, Alcon received a Paragraph IV Certification Letter under the Hatch-Waxman Act notifying Alcon that a generic drug company filed an application with the FDA seeking pre-patent expiry approval to sell a generic version of Simbrinza (brinzolamide/brimonidine tartrate ophthalmic suspension) 1%/0.2%. In October 2022, Alcon filed a patent infringement lawsuit in the US District Court for the District of Delaware against that generic drug company. The lawsuit, which asserts two patents, automatically stays FDA approval of the generic drug application for up to 30 months from receipt of the Paragraph IV Certification Letter (or earlier if the court renders a decision adverse to Alcon). The court has entered a schedule that sets trial for October 2024. Alcon intends to defend its patents in this case vigorously.
On January 31, 2022, prior to Alcon's acquisition of Aerie, Aerie received three Paragraph IV Certification Letters under the Hatch-Waxman Act notifying Aerie that three generic drug companies had filed applications to the FDA seeking pre-patent expiry approval to sell generic versions of Rhopressa and/or Rocklatan. On March 14, 2022, Aerie filed patent infringement
lawsuits in the US District Court for the District of New Jersey against those generic drug companies. These lawsuits automatically stay FDA approval of the generic drug applications for up to 30 months from receipt of the respective Paragraph IV Certification Letters (or earlier if a court renders a decision adverse to Alcon). The lawsuits have been consolidated into a single case with a trial scheduled for January 2025. Alcon has resolved its patent infringement claims against one of the three generic defendants. Alcon continues to vigorously pursue its claims against the remaining two defendants.

The costs were mainly related to accrued severance for the associates whose positions were eliminated.

Alcon believes that its total provisions are adequate based upon currently available information. However, given the inherent difficulties in estimating liabilities in this area, Alcon may incur additional costs beyond the amounts provided. Management believes that such additional amounts, if any, would not be material to Alcon's financial condition but could be material to the results of operations or cash flows in a given period.
Provisions for litigation and other legal matters
Alcon has established provisions for certain litigation and other legal matters, where a potential cash outflow is probable and a reliable estimate can be made of the amount of the outflow. These provisions represent the current best estimate of the total financial effect for these matters. Potential cash outflows reflected in a provision may be fully or partially offset by insurance in certain circumstances.
Alcon has not established provisions for potential damage awards for certain additional legal claims if Alcon currently believes that a payment is either not probable or cannot be reliably estimated. A number of other legal matters are in such early stages or the issues presented are such that Alcon has not made any provisions since it cannot currently estimate either a potential outcome or the amount of any potential losses. For these reasons, among others, Alcon generally is unable to make a reliable estimate of possible loss with respect to such cases. It is therefore not practicable to provide information about the potential financial impact of those cases.
There might also be cases for which Alcon was able to make a reliable estimate of the possible loss or the range of possible loss, but Alcon believes that publication of such information on a case-by-case basis would prejudice Alcon's position in ongoing legal proceedings or in any related settlement discussions. Accordingly, in such cases, information would be disclosed with respect to the nature of the contingency, but no disclosure is provided as to an estimate of the possible loss or range of possible loss.
Note 25 contains additional information on contingencies.
Summary of significant legal proceedings
A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property, including under the Hatch-Waxman Act, and anti-bribery matters such as those under the Foreign Corrupt Practices Act of 1977 ("FCPA"), as amended.
As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow. The following is a summary as of February 27, 2024 of significant legal proceedings to which Alcon or its subsidiaries were or are currently a party.
JJSVI patent dispute
On June 23, 2020, Johnson & Johnson Surgical Vision, Inc. ("JJSVI"), acting through its subsidiaries, filed a patent infringement action in the US District Court in Delaware alleging that the manufacture, use, sale, offer for sale, and/or importation of Alcon’s LenSx Laser System willfully infringes, directly and/or indirectly, one or more claims of 12 US patents. JJSVI subsequently amended its complaint to include copyright infringement claims relating to, among other things, source code used in the LenSx Laser System as well as additional claims of patent infringement. Also beginning on June 23, 2020, JJSVI filed claims in Mannheim, Germany, alleging that Alcon directly infringes certain European patents through its manufacture and sale of LenSx. In these cases, JJSVI sought monetary and injunctive relief. Alcon defended all of these cases vigorously and asserted various patent infringement and invalidity claims against JJSVI in Europe and the US. Prior to the trial on the copyright claims in the Delaware action set for February 2023, the parties entered into a confidential settlement agreement to resolve all of the pending legal proceedings described above. As part of that resolution, the parties exchanged cross-licenses of certain intellectual property and other mutually agreed covenants and releases, and Alcon made a one-time payment to JJSVI of $199 million on April 3, 2023, which was accrued as of December 31, 2022, for those rights and to resolve the parties’ various worldwide intellectual property disputes concerning femtosecond laser-assisted cataract surgery devices. This case is now concluded.
Asia / Russia investigation
In 2017 and 2018, Alcon and Novartis Group companies, as well as certain present and former executives and associates of Alcon and Novartis, received document requests and subpoenas from the US Department of Justice (“DoJ”) and the SEC requesting information concerning Alcon accounting, internal controls and business practices in Asia and Russia, including revenue recognition for surgical equipment and related products and services and relationships with third party distributors, both before and after Alcon became part of the Novartis Group. The investigations by the DoJ and the SEC have concluded. On June 25, 2020, Alcon entered into a three-year Deferred Prosecution Agreement ("DPA") with the DoJ regarding a charge that Alcon Pte Ltd. conspired to falsify financial books and records in violation of the US FCPA. The charge relates to payments made by a former distributor to health care providers in Vietnam between 2007 and 2014. Alcon agreed to pay the DoJ a penalty of $8.925 million, for which Novartis has indemnified Alcon. The DPA expired on June 25, 2023. On December 21, 2023, in accordance with the DPA, the DoJ filed a request with the US District Court for the District of New Jersey to dismiss the criminal charge against Alcon Pte Ltd. with prejudice. On December 21, 2023, the Court issued an order dismissing the charge against Alcon Pte Ltd. with prejudice. This case is now concluded.
Hoya patent dispute
On December 11, 2020, Hoya Corporation and one of its affiliates (collectively, "Hoya") filed suit against Alcon in the US District Court for the Northern District of Texas alleging that Alcon's UltraSert Pre-Loaded Delivery System infringes six of Hoya's US patents. The court denied in part Alcon’s motion to dismiss Hoya’s complaint on September 20, 2021. On December 13, 2023, the court denied Hoya’s motion for summary judgment with respect to Alcon’s defense that Hoya derived the subject matter of the asserted patents from certain Alcon products. On January 11, 2024, the court granted Alcon’s motion for summary judgment of non-infringement with respect to three of the six asserted patents and certain claims of the other three asserted patents, and also granted Alcon’s motion for summary judgment with respect to Hoya’s claim that Alcon’s alleged infringement was willful. This matter was fully and finally resolved prior to the trial scheduled to begin on February 20, 2024.
Hatch-Waxman patent litigation
From time to time, Alcon is a party to certain patent infringement proceedings in the US in connection with Notices of Paragraph IV Certification under the Hatch-Waxman Act received from third-party generic manufacturers respecting their applications for generic versions of certain products sold by or on behalf of Alcon, including Simbrinza, Pataday, Rhopressa and Rocklatan, or other similar suits.
During the third quarter of 2022, Alcon received a Paragraph IV Certification Letter under the Hatch-Waxman Act notifying Alcon that a generic drug company filed an application with the FDA seeking pre-patent expiry approval to sell a generic version of Simbrinza (brinzolamide/brimonidine tartrate ophthalmic suspension) 1%/0.2%. In October 2022, Alcon filed a patent infringement lawsuit in the US District Court for the District of Delaware against that generic drug company. The lawsuit, which asserts two patents, automatically stays FDA approval of the generic drug application for up to 30 months from receipt of the Paragraph IV Certification Letter (or earlier if the court renders a decision adverse to Alcon). The court has entered a schedule that sets trial for October 2024. Alcon intends to defend its patents in this case vigorously.
On January 31, 2022, prior to Alcon's acquisition of Aerie, Aerie received three Paragraph IV Certification Letters under the Hatch-Waxman Act notifying Aerie that three generic drug companies had filed applications to the FDA seeking pre-patent expiry approval to sell generic versions of Rhopressa and/or Rocklatan. On March 14, 2022, Aerie filed patent infringement
lawsuits in the US District Court for the District of New Jersey against those generic drug companies. These lawsuits automatically stay FDA approval of the generic drug applications for up to 30 months from receipt of the respective Paragraph IV Certification Letters (or earlier if a court renders a decision adverse to Alcon). The lawsuits have been consolidated into a single case with a trial scheduled for January 2025. Alcon has resolved its patent infringement claims against one of the three generic defendants. Alcon continues to vigorously pursue its claims against the remaining two defendants.

21.1 Acquisition of business
Fair value of assets and liabilities arising from acquisition of business
There were no acquisitions of businesses in 2023 or 2021. During 2022, cash paid for the acquisition of a business, net of cash acquired, was $666 million for Aerie Pharmaceuticals, Inc. described below.
Vision care - Acquisition of Aerie Pharmaceuticals, Inc.
On November 21, 2022, Alcon acquired 100% of the outstanding shares and equity of Aerie, a pharmaceutical company focused on the discovery, development, manufacturing and commercialization of first-in-class ophthalmic therapies. The acquisition includes with the business among other assets, two commercial pharmaceutical ophthalmic eye drop products, Rocklatan and Rhopressa, as well as AR-15512, a Phase 3 product candidate for dry eye disease, and a pipeline of several ophthalmic pharmaceutical product candidates. This transaction helps bolster Alcon’s presence in the ocular health space with its portfolio of commercial products and development pipeline within the Vision Care reportable segment. Pursuant to the terms of the Agreement and Plan of Merger, Alcon paid $15.25 per share to acquire all outstanding shares of Aerie. The total purchase consideration amounted to $744 million and total cash paid for the net identifiable assets recognized, net of cash acquired, was $666 million.
The preliminary PPA for the Aerie acquisition was not finalized as of the date the 2022 financial statements were issued as the fair values of the acquired assets and assumed liabilities were provisional pending final measurement of the purchase consideration. Alcon's consolidated financial statements as of December 31, 2022 reflected the allocation of the purchase price based on a preliminary fair value assessment of the assets acquired and liabilities assumed. The PPA was subsequently finalized during the third quarter of 2023 and resulted in the reversal of a tax reserve with a corresponding decrease in goodwill. The below table summarizes the final PPA for the Aerie business combination as of December 31, 2023.

Alcon retrospectively adjusted the provisional amounts that were recognized at acquisition date, resulting in Current income tax liabilities of $175 million and Goodwill of $8,926 million as of December 31, 2022.
The short-term investments were liquidated in 2022 subsequent to the acquisition.
Provisions and other non-current liabilities recognized at the Aerie acquisition date included a contingent liability related to uncertainty associated with potential contractual payment obligations tied to the assertion of certain third party patents in certain markets. During the third quarter of 2023, the contingent liability of $58 million was released and recognized in Other income following the resolution of the uncertainty.
The goodwill is attributable to assembled workforce and pharmaceutical research and development capabilities, including early stage compounds under development. The goodwill is not deductible for tax purposes.
Direct acquisition costs of $20 million were recognized in Other expense in the 2022 Consolidated Income Statement and were reported in operating cash flows in the 2022 Consolidated Statement of Cash Flows.
Post-acquisition net sales and net loss attributable to Aerie
For the period from the date of the Aerie acquisition, November 21, 2022, through December 31, 2022, the acquired business increased Alcon's 2022 net sales by $16 million and reduced Alcon's 2022 net income by $32 million.
Unaudited Alcon consolidated pro forma net sales and net income
If the Aerie acquisition had occurred on January 1, 2022, unaudited consolidated pro forma net sales and net income for the twelve months ended December 31, 2022 would have been approximately $8,776 million and $192 million, respectively. This pro forma information is presented for illustrative purposes only and may not be indicative of the results of operations that would have actually occurred. In addition, future results may vary significantly from the results reflected in the pro forma information. These estimated amounts have been calculated using Aerie's results of operation beginning January 1, 2022 and adjusting them for:
alignment of the accounting policies between Alcon and Aerie;
additional amortization that would have been charged assuming the fair value adjustments to inventories and intangible assets had been applied from January 1, 2022;
add back of interest expense from Aerie's convertible senior notes to pro forma net income assuming senior notes would have been repaid on January 1, 2022;
additional interest expense that would have been recorded assuming the Series 2032 Notes and Series 2052 Notes were issued on January 1, 2022 to the extent the proceeds were used to refinance the 2022 Bridge Loan Facility;
exclusion of Aerie's pre-acquisition transaction costs; and
tax effects of the above adjustments.
21.2 Acquisitions of assets
Acquisitions of assets in 2023 amounted to $2 million. During 2022, cash paid for acquisitions of assets, net of cash acquired, was $485 million, the most significant of which was $477 million paid for Ivantis, Inc., described below. There were no acquisitions of assets in 2021.

Surgical - Acquisition of Ivantis, Inc.
On January 7, 2022, Alcon acquired 100% of the outstanding shares and equity of Ivantis, Inc., a privately-held, US-based company and manufacturer of the Hydrus Microstent, a MIGS device designed to lower intraocular pressure for open-angle glaucoma patients. The acquisition expands Alcon’s surgical portfolio and is expected to help provide a platform for more growth in the glaucoma space. Pursuant to the terms and subject to the conditions of the Option Agreement and Plan of Merger, as amended, Alcon agreed to pay total upfront consideration of $479 million and additional amounts to be potentially paid upon achievement of a development milestone and commercial milestones calculated as a percentage of sales in excess of defined targets that expire in calendar year 2024.
The acquisition was accounted for as an asset acquisition rather than a business combination as substantially all of the fair value of the gross assets acquired is concentrated in the value of the Hydrus Microstent commercially marketed product intangible assets, being a group of identifiable assets. Consequently, a relative fair value approach was taken for allocating the consideration to the acquired assets and liabilities with no goodwill recognized.
During 2022, total cash paid for the acquisition, net of cash acquired, was $477 million. Direct acquisition costs of $2 million were capitalized.

Post-employment benefits for associates

Employee Benefits [Abstract]  
Post-employment benefits for associates Post-employment benefits for associates
Defined benefit plans
In addition to the legally required social security schemes, Alcon has sponsored numerous independent pension and other post-employment benefit plans. In most cases, these plans are externally funded in entities that are legally separate from Alcon. For certain subsidiaries, however, no independent plan assets exist for the pension and other post-employment benefit obligations of associates. In these cases the related unfunded liability is included in the Consolidated Balance Sheet. The value of the post-employment benefits promised under the pension and other post-employment benefit plans is represented by the defined benefit obligation ("DBO"), which is measured based on the projected unit credit method ("PUC"). Independent actuaries reappraise the DBOs of all major pension and other post-employment benefit plans annually. Plan assets are recognized at fair value.
The major pension and other post-employment benefit plans are based in Switzerland, the United States, Germany, and the United Kingdom. As of December 31, 2023, these plans represent 88% of Alcon's total DBO and are independently sponsored by Alcon. Details of the plans in those significant countries are provided below.
The pension plans in Switzerland represent the most significant portion of Alcon's total pension DBO and total plan assets. The principal plan in Switzerland is funded and open for new joiners. For the Swiss pension plan, active insured members' benefits are partially linked to the contributions paid into the plan. Certain features of the Swiss pension plan required by law preclude the plan from being categorized as a defined contribution plan. These factors include a minimum interest guarantee on retirement savings accounts, a pre-determined factor for converting the accumulated savings account balance into a pension and embedded death and disability benefits. All benefits granted under a Swiss-based principal
pension plan are vested, and Swiss legislation prescribes that the employer has to contribute a fixed percentage of an associate's pay to an external pension trust. Additional employer contributions may be required whenever the foundation's statutory funding ratio falls below a certain level. The associate also contributes to the plan.
Alcon's Swiss pension obligation is set-up under an Alcon-sponsored arrangement affiliated with Copré La Collective de Prévoyance ("Copré") – a Swiss collective foundation. As a collective foundation, Copré is governed by its own board of trustees which is responsible for the foundation regulations and asset investment strategy for multiple entities participating in the collective foundation. Alcon maintains its own pension committee, consisting of representatives nominated by Alcon and the active insured associates. During the fourth quarter of 2021, Copré announced the rates to be used to convert participant balances to pension annuities for 2024 to 2026. This announcement resulted in a plan amendment with a benefit of $15 million recognized in Other income and a corresponding decrease in the DBO. During the third quarter of 2023, Copré announced that the rates to be used to convert participant balances to pension annuities will remain constant until 2028.
The United States pension plans represent the second largest component of Alcon's total pension DBO and total plan assets. The principal plan (Qualified Plan) is funded, whereas the plans providing additional benefits for executives (Defined Benefit Restoration Plan and Grandfathered Supplemental Executive Plan) are unfunded. Benefits in the Qualified Plan and Restoration Plan are frozen for all participants. Employer contributions are required for the Qualified Plan whenever the statutory funding ratio falls below a certain level. Furthermore, the United States other post-employment benefit plans (US OPEB plans) represent 98% of the total DBO for other post-employment benefit plans. These benefits in the US primarily consist of post-employment healthcare which has been closed to new members since 2015. Effective January 1, 2021, the Alcon sponsored group health plan for current and future eligible retired participants age 65 and over utilizes a private Medicare marketplace while providing an annual notional contribution to a Health Reimbursement Account for each covered member and spouse. There is no statutory funding requirement for the US OPEB plans.
The major pension arrangements in Germany are governed by the Occupational Pensions Act ("BetrAVG") and represent the third largest component of Alcon's total pension DBO and the fifth largest component of Alcon's total plan assets. The plans are partly funded by a Contractual Trust arrangement or direct insurances. The employer is responsible for contributing the premiums to the insurances and paying certain benefits when they fall due. All plans are closed for new entrants and the benefits are fully vested for all participants. For some participants the benefits are based on final salary and length of employment, and for others the benefit is earned each year based on the current salary in the year of service. Associates do not contribute towards the cost of the benefits.
The pension plan in the United Kingdom represents the fourth largest component of Alcon's total pension DBO and the third largest component of Alcon's total plan assets. The plan is closed with only former Alcon associates entitled to current or future benefits. The Alcon United Kingdom Pension Scheme is governed and administered by a board of trustees in accordance with its Trust Deed. United Kingdom legislation requires that pension schemes are funded prudently (i.e., to a level in excess of the "best estimate" expected cost of providing benefits). Funding is assessed on a triennial basis using assumptions agreed by the board of trustees and Alcon. The board of trustees is responsible for jointly agreeing with Alcon the level of contributions needed to eliminate any shortfall over a reasonable period of time, typically not exceeding 10 years. Under the governing documentation, if a surplus remains once liabilities have been settled it would be refunded to Alcon.
Alcon has certain pension plans with a surplus that are not recognized on the basis that future economic benefits are not available to the entity in the form of a reduction in future contributions or a cash refund.

Switzerland1.9 %2.2 %
United States5.0 %5.3 %5.0 %5.3 %
Germany3.1 %3.7 %
United Kingdom4.5 %4.8 %
Changes in the aforementioned actuarial assumptions can result in significant volatility in the accounting for pension plans and other post-employment benefit plans in the Consolidated Financial Statements. This can result in substantial changes in Alcon's other comprehensive income, non-current liabilities and prepaid pension assets.
The DBO is significantly impacted by assumptions related to the rate used to discount the actuarially determined post-employment benefit liability. This rate is based on yields of high-quality corporate bonds in the country of the plan. Decreasing corporate bond yields decrease the discount rate. A decrease in the discount rate results in an increase in the DBO and a decrease in the funded status.
The impact of decreasing interest rates on a plan's assets is more difficult to predict. A significant part of plan assets is invested in bonds. Bond values typically are inversely correlated to interest rates. Bond values usually increase when interest rates fall and may therefore partially offset the decrease in the funded status. Furthermore, pension assets also
include significant holdings of equity instruments. Share prices tend to rise when interest rates decrease and therefore often offset the negative impact of the increasing DBO on the funded status (although the correlation of interest rates with returns on equities is not as strong as with bonds, especially in the short term).
The assumption for the expected rate for pension increases significantly affects the DBO of most plans in Switzerland, Germany and the United Kingdom. While the average rate remained flat at 1.1% in the current year, such pension increases generally decrease the funded status, although there is no strong correlation between the value of the plan assets and pension/inflation increases.
Assumptions regarding life expectancy significantly impact the DBO. While the life expectancy assumption remained flat in the current year, generally an increase in longevity increases the DBO. There is no offsetting impact from the plan assets, as no longevity bonds or swaps are held by the pension funds. Generational mortality tables are used where this data is available.
The following table shows the sensitivity of the defined benefit pension and other post-employment benefit obligations to the principal actuarial assumptions as of December 31, 2023:
($ millions)

25 basis point increase in rate of salary increase
25 basis point decrease in rate of salary increase(3)
(1)Decrease in rate of pension increase is limited to zero.
The above sensitivity analyses are based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes of the assumptions may be correlated. When calculating the sensitivity of the DBO to significant actuarial assumptions the same method (present value of the defined benefit obligation calculated with the PUC method at the end of the reporting period) has been applied as when calculating the net liability recognized in the Consolidated Balance Sheet.

Cash and most of the equity and debt securities have a quoted market price in an active market. Real estate and alternative investments, which include hedge fund and private equity investments, usually do not have a quoted market price.
The strategic allocation of assets of the different pension plans is determined with the objective of achieving an investment return that, together with employer contributions and contributions of associates (where applicable), is sufficient to manage the various funding risks of the plans. Based upon the market and economic environments, actual asset allocations may temporarily be permitted to deviate from policy targets.
The weighted average duration of the DBO is 12.4 years and 11.6 years as of December 31, 2023 and December 31, 2022, respectively.
Alcon's ordinary contribution to the various pension plans is based on the rules of each plan and its respective country. Additional contributions are made whenever required by local statute or law (i.e., usually when statutory funding levels fall below predetermined thresholds).

Long-term Incentive Plan ("LTIP") - Restricted Stock Units and Restricted Stock Awards
Under Alcon's LTIP, certain associates may receive grants of RSUs and RSAs (together "Restricted awards"). The awards generally vest on the third anniversary of the award and are generally forfeited if the employment relationship with Alcon terminates prior to vesting. Recipients of RSU awards do not have any shareholder rights, such as voting or dividend rights, until the shares are delivered. Alcon associates receiving grants of RSAs are entitled to the dividends that may be declared and paid over the vesting period only if the associates vest in such award.
LTIP - Performance Stock Units
The Alcon CEO and certain senior-level associates participate in Alcon's long-term performance program. PSUs granted under the LTIP each convert to unrestricted Alcon Inc. shares at vesting, subject to the achievement of performance measures.
PSUs awarded to plan participants are granted at target incentive ranges from 35% to 430% of base compensation and vest over a three-year period. The payout between 0% and 200% of target is dependent upon four equally weighted performance metrics which are determined at the onset of the performance period by the Board. The metrics include compound annual growth rate of Net sales, compound annual growth rate of core earnings per share, market share of peers, and innovation. The Board and the Compensation Committee assess the performance against the defined measures, including input from the Innovation Committee for the innovation metric, and approve the final payout. PSUs granted under the performance plan do not carry voting rights, but do carry dividend equivalents that are paid in cash or Alcon Inc. shares at vesting, provided participants remain associates of Alcon.
Swiss Employee Share Ownership Plan and other share savings plans
Alcon associates in certain countries are encouraged to invest in share savings plans. Under the share savings plans, participants may elect to receive some of their wages or annual incentives in Alcon Inc. shares in lieu of cash. Subject to plan rules and limitations, as a reward for their participation in the share savings plans, at no additional cost to the participant, Alcon may partially match their investments in shares after a holding period of 3 years.

Alcon entered into various purchase commitments for services and materials as well as for equipment in the ordinary course of business. These commitments are generally entered into at current market prices and reflect normal business operations. For disclosure of Property, plant and equipment purchase commitments, see Note 8.
Contingencies
The Alcon companies have to observe the laws, government orders and regulations of the country in which they operate.
A number of Alcon companies are, and will likely continue to be, subject to various legal proceedings and investigations that arise from time to time, including proceedings regarding product liability, sales and marketing practices, commercial disputes, employment, wrongful discharge, antitrust, securities, health and safety, environmental, tax, international trade, privacy, intellectual property including under the Hatch-Waxman Act, and anti-bribery matters such as those under the FCPA, as amended. As a result, Alcon may become subject to substantial liabilities that may not be covered by insurance and could affect Alcon's business, financial position and reputation. While Alcon does not believe that any of these legal proceedings will have a material adverse effect on its financial position, litigation is inherently unpredictable and large judgments sometimes occur. As a consequence, Alcon may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations or cash flow.
Governments and regulatory authorities around the world have been stepping up their compliance and law enforcement activities in recent years in key areas, including marketing practices, pricing, corruption, trade restrictions, embargo legislation, insider trading, antitrust, cybersecurity and data privacy. Further, when one government or regulatory authority undertakes an investigation, it is not uncommon for other governments or regulators to undertake investigations regarding the same or similar matters. Responding to such investigations is costly and requires an increasing amount of management's time and attention. In addition, such investigations may affect Alcon's reputation, create a risk of potential exclusion from government reimbursement programs in the United States and other countries, and may lead to (or arise from) litigation. These factors have contributed to decisions by Alcon and other companies in the healthcare industry, when deemed in their interest, to enter into settlement agreements with governmental authorities around the world prior to any formal decision by the authorities or a court. Those government settlements have involved and may continue to involve, in current government investigations and proceedings, large cash payments, sometimes in the hundreds of millions of dollars or more, including the potential repayment of amounts allegedly obtained improperly and other penalties, including treble damages. In addition, settlements of government healthcare fraud cases often require companies to enter into corporate integrity agreements, which are intended to regulate company behavior for a period of years. Also, matters underlying governmental investigations and settlements may be the subject of separate private litigation.
While provisions have been made for probable losses, which management deems to be reasonable or appropriate, there are uncertainties connected with these estimates. Note 18 contains additional information on these matters.
Alcon is involved in legal proceedings concerning intellectual property rights. The inherent unpredictability of such proceedings means that there can be no assurances as to their ultimate outcome. A negative result in any such
proceeding could potentially adversely affect the ability of certain Alcon companies to sell their products, or require the payment of substantial damages or royalties.
Alcon's potential for environmental remediation liability is assessed based on a risk assessment and investigation of the various sites identified by Alcon as at risk for environmental remediation exposure. Alcon's future remediation expenses are affected by a number of uncertainties. These uncertainties include, but are not limited to, the method and extent of remediation, the percentage of material attributable to Alcon at the remediation sites relative to that attributable to other parties, and the financial capabilities of the other potentially responsible parties.
Alcon has no significant environmental liabilities as at December 31, 2023 and 2022 and has incurred no significant remediation costs for the years ended December 31, 2023, 2022 and 2021.

Basis of preparation
Basis of preparation
The accompanying Consolidated Financial Statements present our historical financial position, results of operations, comprehensive income and cash flows in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) (“IFRS Accounting Standards”). Alcon's principal accounting policies are described in this Note.
Principles of consolidation and equity accounting
Principles of consolidation and equity accounting
The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. In the event that the Company has an interest in another entity that is not wholly owned, the assets, liabilities, results of operations and cash flows of such entity are included in the Company's Consolidated Financial Statements, if the Company directly or indirectly has control over such entity. The Consolidated Financial Statements of the Company are prepared in accordance with IFRS as issued by the IASB. They are prepared in accordance with the historical cost convention except for items that are required to be accounted for at fair value. All intercompany transactions and accounts within Alcon were eliminated.
The Company's financial year-end is December 31, which is also the annual closing date of the individual entities' financial statements incorporated into the Consolidated Financial Statements.
Investment in associates
Associated companies are all entities over which Alcon has a significant influence but not control or joint control. This is generally the case where Alcon holds between 20% and 50% of an entity's voting rights. Alcon can also have significant influence over an investee where it holds less than 20% of the voting rights if Alcon has significant transactions with the investee, Alcon has influence over the investee’s policy making decisions through Board representation, Alcon shares significant technical information with the investee or Alcon exchanges personnel with the investee. Investments in associated companies are accounted for using the equity method from the date when the investee is determined to be an associated company until the date when Alcon loses significant influence over the investee. Under the equity method, the investment is initially recognized at cost, and the carrying amount is subsequently increased or decreased, to recognize Alcon's share of profit or loss and other comprehensive income of the associated company after the date of initial recognition. Alcon eliminates its share of profit/(loss) from unrealized gains/(losses) from its transactions with associated companies against the carrying amount of the investment. Dividends received or receivable from associated companies are recognized as a reduction in the carrying amount of the investment.
The use of the equity method is discontinued from the date when the investee is determined to no longer be an associated company. The investment retained after cessation of the equity method is remeasured at fair value, and any gain or loss on such remeasurement and disposal of the investment is recognized in the Consolidated Income Statement.
The carrying amounts of investments in associated companies are tested for impairment when triggering events are identified.
Use of estimates and assumptions
Use of estimates and assumptions
The preparation of Consolidated Financial Statements requires management to make certain estimates and assumptions, either at the balance sheet date or during the period that affect the reported amounts of assets and liabilities as well as revenues and expenses. Because of the inherent uncertainties, actual outcomes and results may differ from management's assumptions and estimates.
Foreign currencies
Foreign currencies
The Consolidated Financial Statements are presented in US dollars ("USD"). The functional currency of individual entities incorporated into the Consolidated Financial Statements is generally the local currency of the respective entity. The functional currency used for the reporting of certain Swiss entities is USD instead of their respective local currencies. This reflects the fact that the cash flows and transactions of these entities are primarily denominated in this currency.
For entities not operating in hyperinflationary economies, the entities results, financial position and cash flows that do not have USD as their functional currency are translated into USD using the following exchange rates:
Income, expense and cash flows using for each month the average exchange rate, with the USD values for each month being aggregated during the year;
Balance sheet using period-end exchange rates; and
Resulting exchange rate differences are recognized in other comprehensive income.
The hyperinflationary economies in which Alcon operates are Argentina, Turkey and Venezuela. Argentina and Venezuela were hyperinflationary for all years presented. Turkey became hyperinflationary effective April 1, 2022, requiring retroactive implementation from January 1, 2022 of hyperinflationary accounting.
Hyperinflationary accounting under IAS 29, Financial Reporting in Hyperinflationary Economies, requires restatement of non-monetary assets and liabilities to the general price index at the end of the period. The income statement and components of comprehensive income are restated for changes in general price index from the period in which the transactions were initially recorded to the end of the reporting period, with the restated amounts translated using period-end exchange rates. Alcon records the impacts of applying IAS 29 in "Other reserves" in the Consolidated Statement of Changes in Equity and "Other financial income & expense" in the Consolidated Income Statement.
Acquisition of assets
Acquisition of assets
Assets separately acquired are initially recognized on the balance sheet at cost if they meet the criteria for capitalization. The capitalized cost of the asset includes the purchase price and any directly attributable costs for bringing the asset into the condition to operate as intended. Expected costs for obligations to dismantle and remove property, plant and equipment when it is no longer used are included in their cost.
Property, plant and equipment
Property, plant and equipment
Property, plant and equipment are depreciated on a straight-line basis over their estimated useful lives. Freehold land is not depreciated. The related depreciation expense is included in the costs of the functions using the asset or "Cost of net sales" in the Consolidated Income Statement.
Property, plant and equipment are assessed for impairment at the cash generating unit ("CGU") level whenever there is an indication that the balance sheet carrying amount may not be recoverable using cash flow projections for the useful life.
The following table shows the respective useful lives for property, plant and equipment:
 Useful life
Buildings and improvements
10 to 40 years
Machinery and other equipment 
Machinery and equipment
5 to 20 years
Furniture and vehicles
5 to 10 years
Computer hardware
3 to 7 years
Business combinations
Business combinations
The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary may include:
Fair values of the assets transferred;
Liabilities incurred to the former owners of the acquired business;
Equity interests issued by the Company;
Fair value of an asset or liability resulting from a contingent consideration arrangement; and
Fair value of any pre-existing equity interest in the subsidiary.
Identifiable assets acquired and liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The excess of the consideration transferred over the fair value of the net identifiable assets acquired is recorded as goodwill, or directly in the income statement if it is a bargain purchase. Alcon primarily uses net present value techniques, utilizing post-tax cash flows and discount rates in estimating the fair value of identifiable assets acquired when allocating the purchase consideration paid for the acquisition. The estimates of the fair values involve significant judgment by management and include assumptions with measurement uncertainty such as the amount and timing of projected cash flows, long-term sales forecasts, the timing and probability of regulatory and commercial success and the discount rate.
Acquisition related costs are expensed as incurred.
Alcon may elect on a transaction-by-transaction basis to apply the optional concentration test to assess whether a transaction qualifies as a business. Under the test, when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, Alcon will account for the transaction as an asset purchase and not a business combination.
If the concentration test is not met, or Alcon elects not to apply this optional test, Alcon will perform an assessment focusing on the existence of inputs and processes that have the ability to create outputs to determine whether the transaction is an asset purchase or a business combination.
Goodwill
Goodwill
Goodwill arises in a business combination and is the excess of the consideration transferred to acquire a business over the underlying fair value of the net identified assets acquired. It is allocated to groups of CGUs which are usually represented by the reportable segments, which are the same as Alcon's operating segments. Goodwill is tested for impairment annually at the level of these groups of CGUs, and any impairment charges are recorded under "Other expense" in the Consolidated Income Statement.
Intangible assets available-for-use and Acquired In-Process Research & Development
Intangible assets available-for-use
Alcon has the following classes of available-for-use intangible assets: Currently marketed products, Marketing know-how, Technologies, Other intangible assets (including software) and the Alcon brand name.
Currently marketed products represent the composite value of acquired intellectual property, patents, and distribution rights and product trade names.
Marketing know-how represents the value attributable to the expertise acquired for marketing and distributing Alcon surgical products.
Technologies represent identified and separable acquired know-how used in the research, development and production processes.
Significant investments in internally developed and acquired software are capitalized and included in the "Other" category and amortized once available for use.
The Alcon brand name is shown separately as it is the only Alcon intangible asset that is available for use with an indefinite useful life. Alcon considers it appropriate that the brand name has an indefinite life since the branded products have a history of strong revenue and cash flow performance, and Alcon has the intent and ability to support the brand with spending to maintain its value for the foreseeable future.
Except for the Alcon brand name, intangible assets available for use are amortized over their estimated useful lives on a straight-line basis and evaluated for potential impairment whenever facts and circumstances indicate that their carrying value may not be recoverable. The Alcon brand name is not amortized, but evaluated for potential impairment annually.
The following table shows the respective useful lives for available-for-use intangible assets and the location in the Consolidated Income Statement in which the respective amortization and any potential impairment charge is recognized:

Acquired In-Process Research & Development ("IPR&D")
Acquired research and development intangible assets, which are still under development and have accordingly not yet obtained marketing approval, are recognized as IPR&D.
IPR&D is not amortized, but evaluated for potential impairment on an annual basis or when facts and circumstances warrant. IPR&D is considered impaired when its balance sheet carrying amount exceeds its estimated recoverable amount, which is defined as the higher of its fair value less costs of disposal ("FVLCOD") and its value in use ("VIU"). Usually, Alcon applies the FVLCOD method for its impairment assessments. Under this approach when evaluating IPR&D for potential impairment, FVLCOD is estimated using net present value techniques utilizing post-tax cash flows and discount rates as there are no direct or indirect observable prices in active markets for identical or similar assets. The estimates used in calculating the net present values involve significant judgment by management and include assumptions with measurement uncertainty such as, the amount and timing of projected cash flows, long-term sales forecasts, discount rate, and the timing and probability of regulatory and commercial success. In the limited cases where the VIU method would be applied, net present value techniques would be applied using pre-tax cash flows and discount rates.
Any impairment charge is recorded in the Consolidated Income Statement under "Research & development".
Once a project included in IPR&D has been successfully developed it is transferred to the "Currently marketed products" category.
Impairment of goodwill, Alcon brand name and definite lived intangible assets
Impairment of goodwill, Alcon brand name and definite lived intangible assets
A CGU to which goodwill has been allocated (reportable segments) is considered impaired when its carrying amount, including the goodwill, exceeds its recoverable amount, which is defined as the higher of its FVLCOD and its VIU. If the recoverable amount of the reportable segment is less than its carrying amount, an impairment loss shall be recognized. The impairment loss shall be allocated to reduce the carrying amount of any goodwill allocated to the reportable segment first, with any remaining impairment loss allocated to other assets of the reportable segment on a pro-rata basis of their carrying amount.
An intangible asset other than goodwill is considered impaired when its balance sheet carrying amount exceeds its estimated recoverable amount, which is defined as the higher of its FVLCOD and its VIU. If the recoverable amount of an asset is less than its carrying amount, the carrying amount of the asset shall be reduced to its recoverable amount. That reduction is an impairment loss. Usually, Alcon applies the FVLCOD method for its impairment assessment. In most cases, no direct or indirect observable market prices for identical or similar assets are available to measure the FVLCOD. Therefore, an estimate of FVLCOD is based on net present value techniques utilizing post-tax cash flows and discount rates. In the limited cases where the VIU method would be applied, net present value techniques would be applied using pre-tax cash flows and discount rates.
FVLCOD reflects estimates of assumptions that market participants would be expected to use when pricing the asset or CGUs, and for this purpose management considers the range of economic conditions that are expected to exist over the remaining useful life of the asset.
The estimates used in calculating the net present values involve significant judgment by management and include assumptions with measurement uncertainty, such as the following:
Amount and timing of projected cash flows;
Long-term sales forecasts, including sales growth rates;
Royalty rate for the Alcon brand name;
Terminal growth rate; and
Discount rate.
Other assumptions used in the net present values calculation include:
Future tax rate;
Actions of competitors (launch of competing products, marketing initiatives, etc.); and
Outcome of R&D activities and forecast of related costs (future product developments).
Generally, for intangible assets with a definite useful life Alcon uses cash flow projections for the whole useful life of these assets. For goodwill and the Alcon brand name, Alcon generally utilizes cash flow projections for a five-year period based on management forecasts, with a terminal value based on cash flow projections considering the long-term expected growth rates and impact of demographic trends of the population to which Alcon products are prescribed, for later periods. Probability-weighted scenarios are typically used.
Discount rates used consider Alcon estimated weighted average cost of capital adjusted for specific country and currency risks associated with cash flow projections to approximate the weighted average cost of capital of a comparable market participant. Actual cash flows and values could vary significantly from forecasted future cash flows and related values derived using net present value techniques.
Cash and cash equivalents
Cash and cash equivalents
Cash and cash equivalents includes cash on hand, deposits held at call with financial institutions, and other short-term and highly liquid investments. Other short-term and highly liquid investments are classified as cash and cash equivalents when original or weighted-average maturities are three months or less and amounts are readily convertible to known amounts of cash which are subject to an insignificant risk of changes in value. Bank overdrafts are usually presented within current financial debts on the Consolidated Balance Sheet except in cases where a right of offset has been agreed with a bank which then allows for presentation on a net basis.
Financial assets
Financial assets
Non-current financial assets such as the long-term note receivable, certain other financial assets, loans and long-term receivables from customers, primarily related to surgical equipment sales arrangements, VAT receivables, advances and other deposits, are carried at amortized cost, which reflects the time value of money, less any allowances for uncollectable amounts.
Alcon assesses on a forward-looking basis the expected credit losses associated with its non-current financial assets valued at amortized cost.
Purchased or originated credit-impaired financial assets are financial assets that are credit-impaired on initial recognition with one or more events that have a detrimental impact on the estimated future cash flows of those financial assets. The interest income of the financial assets is calculated by applying the credit-adjusted effective interest rate to the amortized cost of the financial asset. The calculation does not revert to the gross basis even if the credit risk of the financial asset subsequently improves so that the financial asset is no longer credit-impaired. Interest income is recognized in "Other financial income and expense" in the Consolidated Income Statement.
The lifetime expected credit loss ("ECL") of the purchased or originated credit-impaired financial assets is analyzed at inception and utilized in calculating the credit-adjusted effective interest rate, with no Day 1 impact on the carrying value of the financial assets. The value of any collateral related to the financial assets is considered in estimating the lifetime ECL at inception. For purchased or originated credit-impaired financial assets, a credit-adjusted effective interest rate is calculated by discounting the estimated future cash flows, including ECLs, to the amortized cost of the debt instrument on initial recognition. Any change in the lifetime ECL from inception would be reflected as a credit loss in the Consolidated Income statement.
For loans, VAT receivables, advances and other deposits valued at amortized cost, impairments, which are based on their expected credit losses, and exchange rate losses are included in "Other expense" in the Consolidated Income Statement
and exchange rate gains and interest income, using the effective interest rate method, are included in "Other income" in the Consolidated Income Statement.
For long-term receivables from customers, provisions for uncollectable amounts, which are based on their expected credit losses, are recorded as marketing and selling costs recognized in the Consolidated Income Statement within "Selling, general & administration" expenses.
Fund investments are valued at fair value through profit and loss ("FVPL"). Unrealized or realized gains and losses, including exchange gains and losses, are recognized in the Consolidated Income Statement in "Other income" for gains and "Other expense" for losses.
Equity investments, including equity securities and convertible notes receivable held as strategic investments are generally designated at the date of acquisition as financial assets valued at fair value through other comprehensive income ("FVOCI") with no subsequent recycling through profit and loss. Unrealized gains and losses, including exchange gains and losses, are recorded as a fair value adjustment in the Consolidated Statement of Comprehensive Income. They are reclassified to "Other reserves" when the equity investment is sold. If these equity securities and convertible notes receivable are not designated at the date of acquisition as financial assets valued at FVOCI, they are valued at FVPL, as described above for fund investments. Changes in fair value of options to acquire development stage companies are charged to Research and development expense.
Derivative financial instruments are initially recognized in the Consolidated Balance Sheet at fair value and are remeasured to their current fair value at the end of each subsequent reporting period. The valuation of forward exchange rate contracts and foreign exchange swaps are based on the discounted cash flow model, using interest curves and spot rates at the reporting date as observable inputs. Unsettled forward contracts and swaps are measured at fair value at quarter-end with changes in fair value recorded to the Consolidated Income Statement as unrealized gains or losses in "Other financial income & expense". Settled forward contracts and swaps are measured at maturity date at fair value with corresponding realized gains or losses recognized in the Consolidated Income Statement in "Other financial income & expense". No hedge accounting is applied for these arrangements.
Inventories
Inventories
Inventory is valued at the lower of acquisition or production cost determined on a first-in, first-out basis and net realizable value. This value is used for the "Cost of net sales" and "Cost of other revenues" in the Consolidated Income Statement. Unsalable inventory is fully written off in the Consolidated Income Statement under "Cost of net sales" and "Cost of other revenues".
Trade receivables
Trade receivables
Trade receivables are initially recognized at their invoiced amounts, including any related sales taxes less adjustments for estimated revenue deductions such as chargebacks and cash discounts.
Provisions for expected credit losses are established using an expected credit loss model ("ECL"). The provisions are based on a forward-looking ECL, which includes possible default events on the trade receivables over the entire holding period of the trade receivable. These provisions represent the difference between the trade receivable's carrying amount and the estimated net collectible amount. Charges for doubtful trade receivables are recorded as marketing and selling costs recognized in the Consolidated Income Statement within "Selling, general & administration" expenses.
Leases
Leases
As lessee, Alcon assesses whether a contract contains a lease at inception or modification of a contract based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Alcon allocates contractual payments between lease and non-lease components based on their relative stand-alone price. Alcon recognizes a right-of-use asset and a corresponding lease liability for all arrangements in which it is a lessee, except for leases with a term of twelve months or less (short-term leases) and low value leases for which Alcon has elected the recognition exemptions allowed under IFRS 16.
Right-of-use assets
Right-of-use assets are initially recognized at cost, which is comprised of the amount of the initial measurement of the corresponding lease liabilities, adjusted for any lease payments made at or prior to the commencement date of the lease, lease incentives received and initial direct costs incurred, as well as any expected costs for obligations to dismantle and remove right-of-use assets when they are no longer used.
Right-of-use assets are depreciated on a straight-line basis over the shorter of the useful life of the right-of-use asset or the end of the lease term.
Right-of-use assets are assessed for impairment whenever there is an indication that the balance sheet carrying amount may not be recoverable using cash flow projections for the useful life.
Lease liabilities
Lease liabilities are accounted for at amortized cost and are initially measured at the present value of future lease payments and are classified as current or non-current based on the due dates of the underlying principal payments. In determining the lease term, Alcon evaluates the renewal options and termination options reasonably certain to be exercised. Lease payments are discounted using the interest rate implicit in the lease or, if not readily determinable, the incremental borrowing rate Alcon would be expected to pay within the respective markets, on a borrowing with a similar term and security. Interest in the period is recorded within "Interest expense" in the Consolidated Income Statement.
Lease liabilities are remeasured for changes in estimated lease term, future lease payments arising from a change in an index or rate, amounts expected to be payable under a residual value guarantee, or in assessment of whether Alcon will exercise a purchase, extension or termination option. Changes to initial lease contract terms are assessed to determine their impact on the scope of lease, and any modifications increasing the scope of the lease are treated as new contracts under the initial measurement principles, while modifications that do not increase or that decrease the scope of the lease result in an adjustment to the right-of-use asset which is remeasured as of the date of the modification.
Principal payments made on lease liabilities and any initial direct costs paid are classified as financing cash outflows, while interest payments are classified as operating cash outflows.
Payments associated with short-term leases and leases of low-value assets are recognized on a straight-line basis as an expense in the Consolidated Income Statement and are classified as cash flows from operating activities.
Legal liabilities
Legal liabilities
Alcon is subject to contingencies arising in the ordinary course of business such as patent litigation and other product-related litigation, commercial litigation, and governmental investigations and proceedings. Provisions are recorded where a reliable estimate can be made of the probable outcome of legal or other disputes.
Contingent consideration
Contingent consideration
In a business combination, it is necessary to recognize contingent future payments to previous owners representing contractually defined potential amounts as a liability. Usually for Alcon, these are linked to development or commercial milestones related to certain assets and are recognized as a financial liability at their fair value, which is then re-measured at each subsequent reporting date.
For the determination of the fair value of a contingent consideration, various unobservable inputs are used. A change in these inputs might result in a significantly higher or lower fair value measurement. The inputs used are, among others, the timing and probability of regulatory and commercial success, sales forecast and assumptions regarding the discount rate, timing and different scenarios of triggering events. The significance and usage of these inputs to each contingent consideration may vary due to differences in the timing and triggering events for payments or in the nature of the asset related to the contingent consideration. These estimations typically depend on factors such as technical milestones or market performance and are adjusted for the probability of their likelihood of payment, and if material, appropriately discounted to reflect the impact of time.
Changes in the fair value of contingent consideration liabilities in subsequent periods are recognized in the Consolidated Income Statement in "Cost of net sales" for currently marketed products and in "Research & development" for IPR&D.
The effect of unwinding the discount over time is recognized in "Interest expense" in the Consolidated Income Statement.
Alcon accounts for variable or contingent consideration associated with asset acquisitions using the cost accumulation model. At the date of the asset acquisition, the intangible asset is initially recognized at the amount paid. Variable payments are subsequently capitalized as part of the cost of the asset when paid, on the basis that such payments represent the direct cost of acquisition.
Defined benefit pension plans and other post-employment benefits and defined contribution plans
Defined benefit pension plans and other post-employment benefits
The liability or asset recognized in the balance sheet in respect of defined benefit pension plans and other post-employment benefits is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method.
The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and
that have terms approximating the terms of the related obligation. In countries where there is no sufficient market for such bonds, the market rates on government bonds are used.
The current service cost for such post-employment benefit plans is included in the personnel expenses of the various functions where the associates are employed. The net interest on the net defined benefit liability is recognized as "Other expense" or "Other income". The net interest cost is calculated by applying the discount rate to the net balance of the defined benefit obligation and the fair value of plan assets. Past service cost is recognized as "Other expense" or "Other income" in the Consolidated Income Statement for the change in the present value of a defined benefit obligation for employee service in prior periods resulting from a plan amendment or a curtailment.
Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.
Defined contribution plans
For defined contribution plans, Alcon contributes to publicly or privately administered plans. Alcon has no further payment obligations once the contributions have been paid. The contributions are included in the personnel expenses of the various functions where the associates are employed.
Financial debts
Financial debts
Financial debts are initially recognized at fair value, net of transaction costs incurred. Financial debts are subsequently measured at amortized cost. Any difference between the proceeds (net of transaction costs and discounts) and the redemption amount is recognized in the Consolidated Income Statement over the period of the financial debts using the effective interest method. Fees paid on the establishment of credit facilities are recognized as transaction costs of the financial debt to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw down occurs. To the extent that there is no evidence that it is probable that some or all of the facility will be drawn down, the fee is capitalized as a prepayment for liquidity services and amortized over the period of the facility to which it relates, and is recognized in "Other financial income & expense" in the Consolidated Income Statement.
Financial debts are derecognized from the balance sheet when the obligation specified in the contract is discharged, cancelled or expired. The difference between the carrying amount of a financial debt that has been extinguished and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognized in "Other financial income & expense" in the Consolidated Income Statement.
Interest paid on financial debts is classified as operating activities in the Consolidated Statement of Cash Flows. Proceeds and repayments of borrowings with due dates of three months or less are presented net as financing activities in the Consolidated Statement of Cash Flows. Financial debts are classified as current liabilities unless Alcon has an unconditional right and intent to defer the settlement of the liability for at least twelve months after the reporting period.
Revenue
Revenue
Net sales to third parties
Revenue on the sale of Alcon products and services, which is recorded as "Net sales to third parties" in the Consolidated Income Statement, is recognized when a contractual promise to a customer (i.e., a performance obligation) has been fulfilled by transferring control over the promised goods and services to the customer, substantially all of which is at the point in time of shipment to or receipt of the products by the customer or when the services are performed. If contracts contain customer acceptance provisions, revenue would be recognized upon the satisfaction of acceptance criteria. The amount of revenue to be recognized is based on the consideration Alcon expects to receive in exchange for its goods and services. If a contract contains more than one performance obligation, the consideration is allocated based on the relative stand-alone selling price of each performance obligation.
Surgical equipment may be sold together with other products and services under a single contract and may be structured as an outright cash sale, an installment sale, or a lease. Surgical equipment installment sales and leases have a fixed payment amount which the customer may pay either in fixed intervals or as the customer purchases consumables and/or implantables. Revenues are recognized upon satisfaction of each of the performance obligations in the contract and the consideration is allocated based on the relative stand-alone selling price of each performance obligation.
Surgical equipment revenue from outright cash sales and installment sales arrangements is recognized at the point in time when control is transferred to the customer. The current portion of long-term receivables from customers and long-term receivables from customers for installment sales arrangements are recorded in "Other current assets" (see "Current portion of long-term receivables from customers" in Note 14) and "Financial
assets" (see "Long-term receivables from customers" in Note 11), respectively. Financing income for installment sales arrangements longer than twelve months is recognized over the term of the arrangement in "Other income". Alcon applies the practical expedient under IFRS 15 to installment sales arrangements that are twelve months or less in duration.
In addition to cash and installment sales, revenue is recognized under finance and operating lease arrangements. Leases in which Alcon transfers substantially all the risks and rewards incidental to ownership to the customer are treated as finance lease arrangements. Revenue from finance lease arrangements is recognized at amounts equal to the fair value of the equipment, which approximates the present value of the minimum lease payments under the arrangements. As interest rates embedded in lease arrangements are approximately market rates, revenue under finance lease arrangements is comparable to revenue for outright sales. Finance income for arrangements longer than twelve months is deferred and subsequently recognized based on a pattern that approximates the use of the effective interest method and recorded in "Other income". Operating lease revenue for equipment rentals is recognized on a straight-line basis over the lease term in "Net sales to third parties".
The consideration Alcon receives in exchange for its goods or services may be fixed or variable. Variable consideration is only recognized when it is highly probable that a significant reversal of cumulative sales will not occur. The most common elements of variable consideration are listed below:
Rebates and discounts granted to government agencies, wholesalers, retail pharmacies, managed health-care organizations and other customers, estimated payments for Medicare Part D prescription drug program coverage gap (commonly called the "donut hole"), patient co-pay program coupon utilization, as well as chargebacks are provisioned and recorded as a deduction from revenue at the time the related revenues are recorded or when the incentives are offered. They are calculated based on historical experience, regulations, the specific terms in the individual agreements, product pricing, channels and payors.
Cash discounts are offered to customers to encourage prompt payment and are provisioned and recorded as revenue deductions at the time the related sales are recorded.
Sales returns provisions are recognized and recorded as revenue deductions when there is historical experience of Alcon agreeing to customer returns and Alcon can reasonably estimate expected future returns. In doing so, the estimated rate of return is applied, determined based on historical experience of customer returns and considering any other relevant factors. This is applied to the amounts invoiced, also considering the amount of returned products to be destroyed versus products that can be placed back in inventory for resale. Where shipments are made on a re-sale or return basis, without sufficient historical experience for estimating sales returns, revenue is only recorded when there is evidence of consumption or when the right of return has expired.
Provisions for revenue deductions are adjusted to actual amounts as rebates, discounts, chargebacks, payment for Medicare Part D prescription drug program, patient co-pay program coupon utilization and returns are processed. The provision represents estimates of the related obligations, requiring the use of judgment when estimating the effect of these sales deductions.
Other revenues
"Other revenues" include revenue from contract manufacturing services which are recognized over time as the service obligations are completed and third party royalty income. Associated costs for contract manufacturing services are recognized in "Cost of other revenues".
Research & development
Research & development
Internal research & development ("R&D") costs are fully charged to "Research & development" in the Consolidated Income Statement in the period in which they are incurred. Alcon considers that regulatory and other uncertainties inherent in the development of new products preclude the capitalization of internal development expenses as an intangible asset until marketing approval from a regulatory authority is obtained in a major market such as the United States, the European Union, Switzerland, China or Japan.
Payments made to third parties to in-license or acquire intellectual property rights and products, including initial upfront and subsequent milestone payments, are capitalized as intangible assets. If additional payments are made to the originator company to continue to perform R&D activities, an evaluation is made as to the nature of the payments. Such additional payments will be expensed if they are deemed to be compensation for subcontracted R&D services not resulting in an additional transfer of intellectual property rights to Alcon. Such additional payments will be capitalized if they are deemed to be compensation for the transfer to Alcon of additional intellectual property developed at the risk of the originator company. Subsequent internal R&D costs in relation to IPR&D and other assets are expensed until such time
that technical feasibility can be proven, as demonstrated by the receipt of marketing approval for the related product from a regulatory authority in a major market.
Equity-based compensation
Equity-based compensation
Each of the periods presented include expense related to incentive compensation provided to eligible Alcon associates in the form of equity-settled or equity-based awards including restricted stock units ("RSUs") and performance stock units ("PSUs").
Alcon expenses the fair values of RSUs and PSUs granted to associates as compensation over the related vesting periods within the various functions where the associates are employed. The fair values of the awards are determined on their grant dates and are adjusted to account for the specific provisions of each of the corresponding grant agreements.
Alcon RSUs do not entitle the recipients to dividends. As such, the fair value upon grant is based on the Alcon share price at the grant date adjusted for potential future dividends to be paid within the holding period. The fair value of these grants, after making adjustments for assumptions related to their forfeiture during the vesting period, is expensed on a straight-line basis over the respective vesting period.
PSUs are subject to certain performance criteria being achieved during the vesting period and require plan participants to provide services during the vesting period. PSUs granted under Alcon's plans are subject to performance criteria based on internal performance metrics. The expense is determined taking into account assumptions concerning performance during the period relative to targets and expected forfeitures due to plan participants not meeting their service conditions. These assumptions are periodically adjusted. Any change in estimates for past services is recorded immediately as an expense or income in the Consolidated Income Statement and amounts for future periods are expensed over the remaining vesting period. As a result, at the end of the vesting period, the total charge during the whole vesting period represents the amount that will finally vest. The number of equity instruments that finally vest is determined at the vesting date.
If a plan participant leaves Alcon for reasons other than retirement, disability or death, then unvested restricted shares, RSUs and PSUs are forfeited, unless determined otherwise by the provision of the plan rules or by the Compensation Committee of the Company's Board of Directors, for example, in connection with a reorganization.
Restructuring charges
Restructuring charges
Restructuring provisions are recognized for the direct expenditures arising from the restructuring, where the plans are sufficiently detailed and where appropriate communication to those affected has been made.
Charges to increase restructuring provisions are included in "Other expense" in the Consolidated Income Statement. Corresponding releases are recorded in "Other income" in the Consolidated Income Statement.
Taxes
Taxes
Taxes on income are expensed in the same periods as the revenues and expenses to which they relate and include any interest and penalties incurred during the period. Deferred taxes are determined using the comprehensive liability method and are calculated on the temporary differences that arise between the tax basis of an asset or liability and its carrying value in the balance sheet prepared for purposes of these Consolidated Financial Statements, except for those temporary differences related to investments in subsidiaries where the timing of their reversal can be controlled and it is probable that the difference will not reverse in the foreseeable future. Alcon recognizes deferred taxes for a new temporary difference where there are previously unrecognized temporary differences, instead of adjusting the amount of those unrecognized differences, for changes in the underlying economics where the initial recognition exemption applies. Since the retained earnings are reinvested, withholding or other taxes on eventual distribution of a subsidiary's retained earnings are only taken into account when a dividend has been planned.
The estimated amounts for current and deferred tax assets or liabilities, including any amounts related to any uncertain tax positions, are based on currently known facts and circumstances. Tax returns are based on an interpretation of tax laws and regulations and reflect estimates based on these judgments and interpretations. The tax returns are subject to examination by the competent taxing authorities which may result in an assessment being made requiring payments of additional tax, interest or penalties. Inherent uncertainties exist in the estimates of the tax positions.
The Organization for Economic Cooperation and Development (“OECD") has published Global Anti-Base Erosion (“GloBE”) Model Rules, which include a minimum 15% tax rate by jurisdiction ("Pillar Two"). For the period ended December 31, 2023, we have applied the IASB amendment to IAS 12, Income Taxes, which provides a mandatory temporary exception from recognizing or disclosing deferred taxes related to Pillar Two.
Earnings per share
Earnings per share
Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding.
New standards and interpretations not yet adopted
New standards and interpretations not yet adopted
Effective January 1, 2024, Alcon will adopt Amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, to clarify the criteria used in determining the classification on the balance sheet of a liability as non-current where an entity has the right to postpone settlement of the liability for at least twelve months after the reporting date. Adoption of the amendment will have an impact on the classification of certain of Alcon's financial debts currently classified as current due to Alcon's expectation to settle the liabilities within twelve months of the balance sheet date, even though Alcon has the right to roll over the financial debts for at least twelve months after the reporting date.
As of December 31, 2023, the current financial debts balance includes $82 million of financial debts that Alcon has a right to roll over for at least twelve months after balance sheet date that will be reclassified to non-current financial debts upon adoption of the Amendments to IAS 1.
Other than previously described, there are no IFRS Accounting Standards, interpretations or amendments not yet effective that would be expected to have a material impact on Alcon upon adoption.
