(11)Directive (EU) 2019/2034 does not limit the classes of instruments that can be used for variable remuneration to a specific class of financial instruments. It should therefore be possible to use synthetic instruments or contracts between staff members and investment firms which are linked to Additional Tier 1 instruments and Tier 2 instruments which can be fully converted or written down. This allows for the introduction of specific conditions in the terms of such instruments which apply only to instruments awarded to staff, without the need to impose such conditions on other investors.
