Accounting principles

Other liabilities

Other liabilities excluding derivatives are classified and subsequently measured at amortized cost.

Derivatives

Derivatives are classified at fair value through profit and loss, with the exception of those that are designated as hedging instruments in a cash-flow hedge.

Contract liabilities

A contract liability is recognized when a payment is received before the performance obligation has been satisfied.
