In January 2016, the International Accounting Standards Board (IASB) issued IFRS 16 “Leases”, which will replace the current standard IAS 17 “Leases”. IFRS 16, whose application is mandatory for annual periods beginning on or after January 2019, sets out new rules for the recognition and measurement of leases, leading to a change of value for the elements recognized in the financial statements, as well as for the financial indicators calculated based on these. The purpose of this article is to present, based on a comparative analysis of IFRS 16 and IAS 17, the main consequences that the application of IFRS 16 will arise, in respect of the financial statements and the financial indicators determined based on the information provided by these.
