The EY benchmarking survey on IFRS 15 reveals that 16 financial institutions, primarily banks, participated, with most planning to adopt the standard starting January 2018. Participants showed a preference for the modified retrospective transition method but expressed uncertainty about significant impacts on their financial statements, although specific areas like wealth management and trade execution may be affected. Discussions with audit committees and external auditors are expected to increase as the implementation deadline approaches, but many institutions are still refining their governance and operational strategies.
