IFRS 16 eliminates the distinction between operating and finance leases, requiring all leases to be capitalized on the balance sheet starting January 1, 2019, with exemptions for short-term leases and low-value assets. The new standards significantly impact financial statements, especially in industries like airlines and retail, and improve comparability by consistently recognizing lease liabilities and assets. Disclosure requirements have been updated to provide more detailed information regarding lease costs and features, affecting financial metrics and ratios.
