IFRS 15 Revenue from Contracts with Customers is the new standard on revenue accounting that significantly impacts revenue recognition and measurement. Its implementation may also have broader implications on tax positions and key performance indicators. IFRS 15 provides clear guidance on when revenue is to be recognised, either over time or at a point in time. It also deals with the presentation of contract assets and contract liabilities, and requires enhanced disclosure requirements on revenue. This book explains the five-step approach to revenue accounting under IFRS 15, including identifying and accounting for separate performance obligations in contracts with customers, sale of goods and rendering of services, licensing arrangements, construction contracts and property development activities. IFRS 16 Leases will have a significant impact on lease accounting for lessees. This IFRS applies a new “rights and obligations” approach for lessee accounting that requires a lessee to capture all assets and liabilities in lease contracts, regardless of whether it transfers substantially all the risks and rewards incidental to ownership. Unlike the current IAS 17, which differentiates between finance and operating leases, IFRS 16 no longer makes this distinction. This new approach will affect reporting entities with significant off-balance sheet operating leases accounted for under the current IAS 17. IFRS 16 also changes the definition of a lease, which may bring within its scope contracts or arrangements that were previously not accounted for as leases under the current IAS 17. This book provides a comprehensive insight on recognising and measuring assets and liabilities for leases, lessee and lessor accounting as well as the new accounting requirements on sale-leaseback and sublease arrangements. These two IFRSs are inter-related since some revenue contracts with customers may contain a lease component whilst some lease contracts may contain a revenue component. In these circumstances, a reporting entity would need to apply both IFRS 15 and IFRS 16. IFRS 15 is effective for financial statements with reporting periods beginning on or after 1 January 2018, while IFRS 16 is effective for financial statements with reporting periods beginning on or after 1 January 2019. This publication takes an issues-based approach and comes with numerous illustrative examples, from simple to complex cases. Most of the cases used in this book are developed from real life situations encountered by the author in the course of his consultancy engagements.
