Notes to the consolidated financial statements as of March 31, 2018

2.1 Changes in accounting policies

In 2017/18 the Group adopted the following minor amendments to existing standards and interpretations, without having a significant impact on the Group’s result and financial position:

The Group has assessed the expected impacts of the various new and revised standards and interpretations that will be effective for the financial year starting April 1, 2018, as summarized below.

IFRS 9 “Financial instrument”: The standard completes the guidance on recognition/derecognition of financial instruments. It includes revised principles on classification and measurement of financial instruments, including a new expected credit loss model for calculating provisions for impairments on financial assets. The Group does not expect a significant impact on the Group's result and financial position and will implement the new standard on April 1, 2018.

IFRS 15 “Revenues from Contracts with Customers”: The standard combines, enhances and replaces specific guidance on recognizing revenue with a new single standard based on a five step approach. The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Under IFRS 15, an entity recognizes revenue when a performance obligation is satisfied. The primary impact for the Group will be on the timing of revenue recognition for the performance obligations related to extended warranties, loss and damage, battery plans, loyalty programs, and on additional revenue related disclosures. The transition will decrease the Group's retained earnings for an estimated amount of CHF 125 million due to the recognition of contract assets/liabilities and release of provisions and deferred revenue. The impact on the income statement will not be material. The Group chose the modified retrospective approach with the recognition of the cumulative effect of initial application in retained earnings and will implement the new standard on April 1, 2018.

Furthermore, the Group is also assessing other new and revised standards which are not mandatory until after the financial year 2018/2019, notably the impacts of IFRS 16 (refer below).

IFRS 16 “Leasing”: The standard will replace IAS 17 and sets out new principles for recognition, measurement, presentation and disclosure of leases. The standard provides a single lessee accounting model, that requires lessees to recognize assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a low value. A lessee is required to recognize a right-of-use asset representing its right to use the underlying asset and a lease liability representing its obligation to make lease payments. The main impact for the Group will be on the recognition of new assets and liabilities for its property lease agreements. In addition, the nature of the expenses related to those leases will now change as IFRS 16 replaces the straight-line operating lease expenses with a depreciation charge for right-of-use assets and interest expenses on lease liabilities. The current operating lease obligations (see Note 32) provide an indication of the impact of IFRS 16 on the Group's consolidated balance sheet. The Group will implement the new standard on April 1, 2019.

2.2 Principles of consolidation

Investments in subsidiaries

Investments in subsidiaries are fully consolidated. These are entities over which Sonova Holding AG directly or indirectly exercises control. Control exists when the Group is exposed, or has rights, to variable returns from its relationship with an entity and has the power to affect those returns. Control is presumed to exist when the parent owns, directly or in­directly through subsidiaries, more than half of the voting power of an entity unless, in exceptional circumstances, it can clearly demonstrate that such ownership does not constitute control. For the consolidated entities, 100% of assets, liabilities, income, and expenses are included. Non-controlling interests in equity and net income or loss are shown separately in the balance sheet and income statement. Changes in the ownership interest of a subsidiary that do not result in a loss of control will be accounted for as an equity trans­action. Hence, neither goodwill nor any gains or losses will result.

Group Companies acquired during the year are included in the consolidation from the date on which control over the company transferred to the Group. Group companies divested during the year are excluded from the consolidation as of the date the Group ceased to have control over the company. Intercompany balances and transactions (including unrealized profit on intercompany inventories) are eliminated in full.

Investments in associates and joint ventures

Investments in associates and joint ventures are accounted for using the equity method of accounting. Investments in associates are entities in which Sonova has a significant influence but does not exercise control (usually 20%–50% of voting rights). Joint ventures are joint arrangements whereby two or more parties have rights to the net assets of the arrangement.

Under the equity method, the investment in an associate/joint venture is recognized initially at cost (including goodwill on acquisition) and the carrying amount is increased or decreased to recognize Sonova’s share of profit or loss of the associate/joint venture after the acquisition date. When the Group’s share of losses in an associate/ joint venture equals or exceeds its interest in the associate/joint venture, no further losses are recognized, unless there is a legal or constructive obligation. In order to apply the equity method the most recent available financial statements of an associate/joint venture are used, however, due to practi­cability reasons the reporting dates might vary up to three months from the Group’s reporting date.

2.3 Currency translation

The consolidated financial statements are expressed in Swiss francs (“CHF”), which is the Group’s presentation ­currency. The functional currency of each Group company is based on the local economic environment to which an entity is exposed, which is normally the local currency.

Transactions in foreign currencies are accounted for at the rates prevailing on the dates of the transactions. The resulting exchange differences are recorded in the local income statements of the Group companies and included in net income.

Monetary assets and liabilities of Group companies which are denominated in foreign currencies are translated using year-end exchange rates. Exchange differences are recorded as an income or expense. Non-monetary assets and liabilities are translated at historical exchange rates. Exchange differences arising on intercompany loans that are considered part of the net investment in a foreign entity are recorded in other comprehensive income in equity.

When translating foreign currency financial statements into Swiss francs, year-end exchange rates are applied to assets and liabilities, while average annual rates are applied to income statement accounts (see Note 5). Translation differences arising from this process are recorded in other comprehensive income in equity. On disposal of a Group company, the related cumulative trans­lation adjustment is transferred from equity to the income statement.

2.4 Accounting and valuation principles

Cash and cash equivalents

This item includes cash on hand and cash at banks, bank overdrafts, term deposits and other short-term highly liquid investments with original maturities of three months or less. The consolidated cash flow statement summarizes the movements in cash and cash equivalents.

Other current financial assets

Other current financial assets consist of financial assets held for trading as well as short-term loans to third parties. Market­able securities within this category are classified as financial assets at fair value through profit or loss (see Note 2.5). Derivatives are classified as held for trading unless they are designated as hedges (see Note 2.6).

Assets in this category are classified as current assets if they are either held for trading or are expected to be ­realized within 12 months.

Trade receivables

Trade receivables are recorded at original invoice amount less provisions made for doubtful accounts. A provision for doubtful accounts is recorded when there is objective ­evidence that the Group will not be able to collect all amounts due according to the original terms of the invoice. The amount of the provision is the difference between the carrying amount and the recoverable amount with the latter being the present value of expected cash flows.

Inventories

Purchased raw materials, components and finished goods are valued at the lower of cost or net realizable value. To evaluate cost, the standard cost method is applied, which approximates historical cost determined on a first-in first-out basis.

Standard costs take into account normal levels of materials, supplies, labor, efficiency, and capacity utilization. Standard costs are regularly reviewed and, if necessary, revised in the light of current conditions. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion (where applicable) and selling expenses.

Manufactured finished goods and work-in-process are valued at the lower of production cost or net realiz­able value.

Provisions are established for slow-moving, obsolete and phase-out inventory.

Property, plant and equipment

Property, plant and equipment is valued at purchase or manu­facturing cost less accumulated depreciation and any impairment in value. Depreciation is calculated on a straight-line basis over the expected useful lifetime of the individual assets or asset categories. Where an asset comprises several parts with different useful lifetimes, each part of the asset is depreciated separately over its applicable useful lifetime. The applicable useful lifetimes are 25 – 40 years for buildings and 3 – 10 years for production facilities, machinery, equipment, and vehicles. Land is not depreciated. Leasehold improvements are depreciated over the shorter of useful life or lease term.

Subsequent expenditure on an item of tangible assets is capitalized at cost only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Expenditure for repair and maintenance which do not increase the estimated useful lifetimes of the related assets are recognized as an expense in the period in which they are incurred.

Leasing

There are no assets that are held under leases which effectively transfer to the Group the risks and rewards of ownership (finance leases). Therefore, all leases are classified as operating leases, and payments are recognized as an expense on a straight-line basis over the lease term unless another systematic basis is more representative of the time pattern of the Group’s benefit.

Intangible assets

Purchased intangible assets such as software, licenses and patents are measured at cost less accumulated amorti­zation (applying the straight-line method) and any impairment in value. Software is amortized over a useful lifetime of 3 – 5 years. Intangibles relating to acquisitions of subsidi­aries (excluding goodwill) consist generally of technology, client relationships, customer lists, and brand names, and are amortized over a period of 3 – 20 years. Other intangible assets are generally amortized over a period of 3 – 10 years. For capitalized development costs in the Cochlear implants segment, amortization starts when the capitalized asset is ready for use, which is generally after receipt of approval from regulatory bodies. These assets are amortized over the estimated useful lifetime of 2 – 7 years applying the straight-line method. For in-process capitalized development costs these capitalized costs are tested annually for impairment. Except for goodwill, the Sonova Group has no intangible assets with an indefinite useful life.

Research and development

Research costs are expensed as incurred. Development costs are capitalized only if the identifiable asset is commercially and technically feasible, can be completed, its costs can be measured reliably and will generate probable future economic benefits. Group expenditures which fulfill these criteria are limited to the development of tooling and equipment as well as costs related to the development of cochlear implants. All other development costs are expensed as incurred. In addition to the internal costs (direct personnel and other operating costs, depreciation on research and development equipment and allocated occupancy costs), total costs also include externally contracted development work. Such capitalized intangibles are recognized at cost less accumulated amortization and impairment losses.

Business combinations and goodwill

Business combinations are accounted for using the acqui­sition method of accounting. The cost of a business combination is equal to the fair values, at the date of exchange, of assets given, liabilities incurred or assumed, and equity instruments issued by the Sonova Group, in exchange for control over the acquired company. Any difference between the cost of the business combination and the net fair value of the identifiable assets, liabilities, and contingent liabilities recognized is treated as goodwill. Goodwill is not amortized, but is assessed for impairment annually, or more frequently if events or changes in circumstances indicate that its value might be impaired. Acquisition-related costs are expensed. For each business combination, the Group recognizes the non-controlling interests in the acquiree at fair value or at the non-controlling interests proportionate share in the recognized amounts of the acquiree’s identifiable net assets.

If a business combination is achieved in stages (control obtained over an associate), the previously held equity interest in an associate is remeasured to its acquisition-date fair value and any resulting gain or loss is recognized in “financial income/expenses” in profit or loss.

Other non-current financial assets

Other non-current financial assets consist of investments in third parties and long-term receivables from associates and third parties as well as rent deposits. Investments in third parties are classified as financial assets at fair value through profit or loss and ­long-term receivables from associates and third parties as well as rent deposits are classified as loans and receivables (see Note 2.5).

Financial liabilities

Current financial liabilities consist of short-term bank debt and all other interest bearing debt with a maturity of 12 months or less. Given the short-term nature of these debts, they are recorded at nominal value. In addition, current financial liabil­ities also consist of financial liabilities resulting from contingent considerations as well as deferred payments (earn-out agreements) from acquisitions with a maturity of 12 months or less. In the case of earn-outs, they are classified as financial liabilities at fair value through profit or loss.

Derivative financial instruments are initially recognized in the balance sheet at fair value and are re-measured to their current fair value at the end of each subsequent reporting period.

Bonds are initially measured at fair value and include direct transaction costs. In subsequent accounting periods, they are re-measured at amortized costs applying the effective interest method.

Provisions

Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, where it is probable that an outflow of resources will be required to settle the obligation, and where a reliable ­estimate can be made of the amount of the obligation. If the effect of the time value of money is material, provisions are determined by discounting the expected future cash flows.

The Group recognizes provisions for warranty costs to cover any costs arising from the warranty given on its products sold (including costs for legal proceedings and related costs). The provision is calculated using historical and projected data on warranty rates, claim rates and amounts, service costs, remaining warranty period and number of hearing instruments and implants on which the warranty is still active. Short-term portions of warranty provisions are reclassified to short-term provisions at each reporting date.

Share capital

Ordinary shares are classified as equity. Dividends on ordinary shares are recorded in equity in the period in which they are approved by the parent companies’ shareholders.

In case any of the Group Companies purchase shares of the parent company, the consideration paid is recognized as ­treasury shares and presented as a deduction from equity. Any consideration received from the sale of own shares is recognized in equity.

Income taxes

Income taxes include current and deferred income taxes. The Group is subject to income taxes in numerous jurisdictions and significant judgment is required in determining the worldwide provision for income taxes. The multitude of transactions and calculations implies estimates and assumptions. The Group recognizes liabilities based on ­estimates of whether additional taxes will be due.

Where the final tax outcome is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Deferred tax is recorded on the valuation differences (temporary differences) between the tax bases of assets and liabilities and their carrying values in the consolidated balance sheet. Deferred tax assets are recognized to the extent that it is probable that future taxable income will be available against which the temporary differences and tax losses can be offset. Deferred income tax liabilities are provided for on taxable temporary differences arising from investments in subsidiaries, except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.

Revenue recognition

Sales are recognized net of sales taxes and discounts when the significant risk and rewards of ownership are transferred to the buyer, mainly upon delivery of products and services and reasonably assured collectability of the related receivables.

For hearing instruments sold, probable returns of products are estimated and a corresponding provision is recognized. The portion of goods sold that are expected to be returned are estimated based on historical product return rates.

For cochlear implants, sales are generally recognized upon delivery to the buyer, mainly hospitals. For returns of products, accumulated experience is used to determine the respective provision.

Revenue from the sale of service is recognized when the service has been provided to the customer and where there are no continuing unfulfilled service obligations. Sales of service contracts, such as long-term service contracts and extended warranties, are separated from the sale of goods and recognized on a straight-line basis over the term of the contract.

Interest income is recognized on a time proportion basis using the effective interest method. Dividend income is recognized when the right to receive payment is established.

Acquisition-related amortization

The Group is continuously amending its business portfolio with acquisitions resulting in acquisition-related intangibles (see section “Intangible Assets”) and related amortization charges. The Group discloses acquisition-related amortization as a separate line item in the income statement, and identifies EBITA as its key profit metric for internal (refer to Note 6) as well as for external reporting purposes. The functional allocation of these acquisition-related amortization costs are further disclosed in Note 20 “Intangible Assets” in the notes to the financial statements.

Segment reporting

Operating segments are defined on the same basis as information is provided to the chief operating decision maker. For the Sonova Group, the Chief Executive Officer (CEO) is the chief operating decision maker, who is responsible for allocating resources and assessing the performance of operating segments. Additional general information regarding the factors used to identify the entity’s reportable segments is disclosed in Note 6.

Impairment of non-financial assets

The Group assesses at each reporting date whether there is any indication that an asset may be impaired. If any such indication exists, the recoverable amount of the asset is estimated. The recoverable amount of an asset or, where it is not possible to estimate the recoverable amount of an individual asset, a cash-generating unit, is the higher of its fair value less cost of disposal and its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit. If the recoverable amount is lower than the carrying amount, an impairment loss is recognized. Impairments of financial assets are described in Note 2.5 “Financial assets”. For the purpose of impairment testing, goodwill as well as corporate assets are allocated to cash generating units. A goodwill impairment test is performed annually, even if there is no indication of impairment (see section “Business combinations and goodwill”).

Related parties

A party is related to an entity if the party directly or indirectly controls, is controlled by, or is under common control with the entity, has an interest in the entity that gives it significant influence over the entity, has joint control over the entity or is an associate or a joint venture of the entity. In addition, members of the Board of Directors and the Management Board or close members of their families are also considered related parties as well as post-employment plan organizations (pension funds) for the benefit of Sonova employees. No related party exercises control over the Group.

Employee benefits

Pension obligations

Most employees are covered by post-employment plans sponsored by corresponding Group companies in the Sonova Group. Such plans are mainly defined contribution plans (future bene­fits are determined by reference to the amount of contributions paid) and are generally administered by autonomous pension funds or independent insurance companies. These pension plans are financed through employer and employee contributions. The Group’s contributions to defined contribution plans are charged to the income statement in the year to which they relate.

The Group also has several defined benefit pension plans, both funded and unfunded. Accounting and reporting of these plans are based on annual actuarial valuations. Defined benefit obligations and service costs are assessed using the projected unit credit method, with the cost of providing pensions charged to the income statement so as to spread the regular cost over the service lives of employees participating in these plans. The pension obligation is measured as the present value of the estimated future outflows using interest rates of government securities which have terms to maturity approximating the terms of the related liability. Service costs from defined benefit plans are charged to the appropriate income statement heading within the operating results.

A single net interest component is calculated by applying the discount rate to the net defined benefit asset or liability. The net interest component is recognized in the income statement in the financial result.

Actuarial gains and losses, resulting from changes in actua­r­ial assumptions and differences between assumptions and actual experiences, are recognized in the period in which they occur in “Other comprehensive income” in equity.

Other long-term benefits

Other long-term benefits are mainly comprised of length of service compensation benefits in certain Group companies. These benefits are accrued and the corresponding liabilities are included under “Other provisions”.

Equity compensation benefits

The Board of Directors of Sonova Holding AG, the Management Board, and certain management and senior employees of other Group companies participate in equity compensation plans. The fair value of all equity compensation awards granted to employees is determined at the grant date and recorded as an expense over the vesting period (for details refer to Note 29). The expense for equity compen­sation awards is charged to the appropriate income statement heading within the operating result and an equivalent increase in equity (for equity-settled compensation) or financial liability (for cash-settled compensation) is recorded. In the case of cash-settled compensation, until the liability is settled, it is revalued at each reporting date, recognizing changes in the fair value in the income statement.

2.5 Financial assets

The Group classifies its financial assets in the categories financial assets at fair value through profit or loss, loans and receivables. Management determines the classification of its investments at initial recognition. All purchases and sales are recognized on the settlement date.

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss consist of cash-settled calls on Sonova shares as a hedge against obligations from share appreciation rights (SARs) allocated to US employees partici­pating in the Executive Equity Award Plan (EEAP) and certain minority investments in hearing instrument related businesses. These financial assets are measured at their fair value. Those fair value changes are included in the profit or loss for the period in which they arise.

Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They arise when the Group provides money, goods or services, directly to a debtor with no intention of trading the receivable. They are included in current assets, except for matu­rities of more than 12 months, that are ­classified as non-current assets. Loans are measured at amortized cost. Amortized cost is the amount at which the financial asset is measured at initial recognition minus principal repayments, plus or minus the cumulative amortization determined by using the effective interest method of any difference between the initial amount and the maturity amount, minus any reduction for impairment or uncollectability. The effective interest method is a method calculating the amortized cost of a ­financial asset and allocating the interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments or receipts through the expected lifetime of the financial instrument or, when appropriate, a shorter period to the net carrying amount of the financial asset.

Impairment of financial assets

A financial asset is impaired if its carrying amount is greater than its estimated recoverable amount. The Group assesses, at each balance sheet date, whether there is any objective evidence that a financial asset may be impaired. If any such evidence exists, the Group estimates the recoverable amount of that asset and recognizes any impairment loss in the income statement. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be objectively related to an event occurring after the write-down, the write-down of the financial asset is reversed. The reversal will not result in a carrying amount of the financial asset that exceeds what the amortized cost would have been, had the impairment not been recognized, at the date the write-down of the financial asset is reversed. The amount of the reversal is included in profit or loss for the financial year.

2.6 Derivative financial instruments and hedging

The Group regularly hedges its net exposure from foreign ­currency balance sheet positions with forward contracts. Such contracts are not qualified as cash flow hedges and are, therefore, not accounted for using hedge accounting. Gains and losses on these transactions are recognized directly in the income statement.

2.7 Significant accounting judgments and estimates

Key management judgments made in applying accounting policies

In the process of applying the Group’s accounting policies, management may be required to make judgments, apart from those involving estimates, which have an effect on the amounts recognized in the financial statements.

These include, but are not limited to, the following areas:

Capitalization of development costs

As outlined under 2.4 “Accounting and valuation principles” the Group capitalizes costs relating to the development of cochlear implants. In determining the commercial as well as the technical feasibility, management judgment may be required.

Business combinations

In the course of recognizing assets and liabilities from ­business combinations, management judgments might be required for the following areas:

Key accounting estimates and assumptions

Preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. This includes estimates and assumptions in the ordinary course of business as well as non-operating events such as the outcome of pending legal disputes. The estimates and assumptions are continuously evaluated and are based on experience and other factors, including expectations of future events that are believed to be reasonable. Actual results may differ from these estimates and assumptions. The main estimates and assumptions with the potential of causing an adjustment, are discussed below.

Cost of business combinations

A business combination agreement may provide for an adjustment to the cost of the combination contingent on future events. If the future events do not occur or the ­estimate needs to be revised, the cost of a business ­combination is revised accordingly, with a resulting change in the income ­statement. At the end of the 2017/18 financial year, such liabilities ­contingent on future events amount to CHF 6.1 million (previous year CHF 10.6 million) and are disclosed under other financial liabilities (Note 22).

Intangible assets, including goodwill

The Group has intangible assets with a carrying value of CHF 2,466.4 million (previous year CHF 2,323.1 million) as disclosed in Note 20.

Included in the intangible assets is goodwill amounting to CHF 1,947.2 million (previous year CHF 1,815.2 million).

Furthermore, intangible assets also include capitalized development costs in the amount of CHF 118.1 million (pre­vious year CHF 100.6 million). The capitalized development costs are reviewed on a regular basis as a matter of a standard systematic procedure. In the current financial year the assessment of the capitalized cost did not lead to any value adjustment. Due to the revision of the Cochlear implants product roadmap in the 2016/17 financial year, Sonova identified in the previous year the need of valuation adjustments on certain R&D projects. As a result, an impairment of previously capitalized development costs was recorded, resulting in a loss amounting to CHF 35.6 million in the previous year. The amount is included in the income statement in the line “other income/(expense), net”.

The Group determines annually, in accordance with the accounting policy stated in Note 2.4, whether any of the assets are impaired. For the impairment tests, estimates are made of the expected future cash flows from the use of the asset or cash-­generating unit. The actual cash flows could vary signifi­cantly from these estimates.

Deferred tax assets

The consolidated balance sheet includes deferred tax assets of CHF 114.6 million (previous year CHF 130.0 million) related to deductible differences and, in certain cases, tax loss carry­forwards, provided that their utilization appears probable. The recoverable value is based on forecasts of the corresponding taxable Group company over a period of several years. As actual results may differ from these forecasts, the deferred tax assets may need to be adjusted accordingly.

Employee benefit plans

The Sonova Group has various employee benefit plans. Most of its salaried employees are covered by these plans, of which some are defined benefit plans. The present value of the defined benefit obligations at the end of the 2017/18 financial period amounts to CHF 373.0 million (previous year CHF 356.5 million) as disclosed in Note 29. This includes CHF 369.1 million (previous year CHF 353.3 million) from the Swiss pension plan. With such plans, actuarial assumptions are made for the pur­pose of estimating future developments, including estimates and assumptions relating to discount rates, and future wage as well as pension trends. Actuaries also use statistical data such as mortality tables and staff turnover rates with a view to determining employee benefit obligations. If these factors change due to a change in economic or market conditions, the subsequent results could deviate considerably from the actuarial reports and calculations. In the medium term, such devi­ations could have an impact on the equity. The carrying amounts of the plan assets and liabilities in the balance sheet, together with a sensitivity analysis considering changes for the main input parameters in the actuarial valuation, are set out in Note 29.

Provisions for warranty and returns

On March 31, 2018, the Group recorded provisions for ­warranty and returns of CHF 125.6 million (previous year CHF 117.5 million) as disclosed in Note 21.

The calculation of these provisions is based on turnover, past experience and projected number and cost of warranty claims and returns. The actual costs for warranty, claims, and returns may differ from these estimates.

Provision for product liabilities

The Sonova Group accounts consider a provision for product liabilities related to products affected by a voluntary cochlear implant product recall of Advanced Bionics LLC in 2006.

The provision for product liabilities is reassessed on a regular and systematic basis. The provision is estimated based on a financial model. Generally, the model used to calculate the provision for the end of the 2017/18 financial year is consistent to the prior year and considers claim rates and cost per case based on historical averages. Improvements in the expected number and cost of current and future claims led to a reversal of CHF 1.8 million in the current financial year 2017/18 (2016/17: reversal of CHF 37.4 million) which contributed to the profit in the same amount (disclosed in the annual income statement in the line “Other income/(expenses), net”).

On March 31, 2018, the provision for the before mentioned cochlear implant product liabilities was CHF 118.4 million (previous year CHF 132.5 million).

The calculation of this provision is based on past experience regarding the number and cost of current and future claims. As actual results may differ from these forecasts, the respective provision may need to be adjusted accordingly.
