2.3 Revenue

The Group generates revenue primarily from the sale of audio devices, hearing instruments, cochlear implants and related services. The following provides a disaggregation of the sales by business and the timing of revenue recognition:

The following table summarizes the contract assets and contract liabilities related to contracts with customers:

Contract liabilities relate to advance consideration received from customers for the Groupʼs various services, such as extended warranties, loss and damage and battery plans. In addition to the contract liabilities, the Group also recognizes contract assets that relate to loss and damage services. Contract assets are presented within other operating assets (refer to Note 3.6) in the consolidated balance sheet.

Significant changes in the contract liabilities during the period are as follows:

No material revenue was recognized in the current period from performance obligations satisfied in previous periods.

Accounting policies

The Group recognizes revenue at point in time when control of the products is transferred to the buyer, mainly upon delivery. The transaction price is adjusted for any variable elements, such as rebates and discounts. For audiological care customers, revenue recognition usually occurs after fitting of the device or when the trial period lapses. For hearing instruments sold in bundled packages (i.e. including accessories and services), the transaction price is allocated to each performance obligation on the basis of the relative stand-alone selling price of all performance obligations in the contract.

For cochlear implants, sales are generally recognized at point in time when control of the products is transferred to the buyer (mainly hospitals), either at delivery or after surgery.

When the customer has a right to return the product within a given period, the amount of revenue is adjusted for expected returns, which are estimated based on historical product return rates. A return provision for the expected returns is recognized as an adjustment to revenue. In addition, an asset for the right to recover returned goods is recognized, measured by reference to the carrying amount, which is presented as part of other current operating assets.

The Group also offers various services, such as extended warranties, loss and damage and battery plans. Revenue for these services is predominantly recognized on a straight-line basis over the service period. In the majority of countries in which the Group operates, the standard warranty period is two years and the extended warranty covers periods beyond the second year. Loss and damage is offered in some, but not all countries, in which the Group operates. This service assures replacement of hearing instruments that are not covered by the warranty. In some countries, the Group reinsures loss and damage. Insurance costs are capitalized as contract assets and are recognized as cost of sales over the loss and damage service period.

Payment terms vary significantly across countries and also depend on whether the customer is a private or public customer.

Accounting judgements and estimates

In order to allocate the transaction price to each performance obligation in a contract, management estimates the standalone selling price of the products and services at contract inception. Mostly, the standalone selling price is based on established price lists. For loss and damage services, management considers the likelihood of a customer claim in the calculation of the standalone selling price.

If the sum of the standalone selling prices of a bundle of goods or services exceeds the consideration in a contract, the discount is allocated proportionally to all of the performance obligations in the contract unless there is observable evidence that the discount relates to only one or some of the performance obligations.
