- Definition The explanation of the difference between: (a) operating lease commitments disclosed applying IAS 17 at the end of the annual reporting period immediately preceding the date of initial application of IFRS 16, discounted using the incremental borrowing rate at the date of initial application; and (b) lease liabilities recognised in the statement of financial position at the date of initial application of IFRS 16. The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Name IFRS -Number 16 -IssueDate 2019-01-01 -Paragraph C12 -Subparagraph b -URI http://eifrs.ifrs.org/eifrs/xifrs-link?type=IFRS&num=16&code=ifrs-tx-2019-en-r&anchor=para_C12_b&doctype=Appendix&subtype=C -URIDate 2019-03-27 + Details
