IFRS 15 replaces IAS 11, IAS 18, IFRIC 13, IFRIC 15, IFRIC 18 and SIC-31. IFRS 15 provides a comprehensive framework for recognising revenue from contracts with customers. In September 2015 the Board issued Effective Date of IFRS 15 which deferred the mandatory effective date of IFRS 15 to 1 January 2018.
