[ESMA 70-1861941480-56 MiFIR data reporting Q&A, Q&A 11.1]

In the case of Bonds or other forms of securitised debt, a trading venue should update Field 14 (Total issued nominal amount) accordingly if the total nominal amount changes (increasing or decreasing). The same approach should be applied to Field 17 (Nominal value per unit/minimum traded value). Trading venues are not expected to report under Field 14 the total size of the issuance programme (i.e. the total nominal amount that can be issued under this programme) under which the specific instruments have been issued but only the nominal amount effectively issued for the specific ISIN being reported (and taking into account the tap issuances and buy-backs that might occur for this specific ISIN).
