The words on this page

Buffer
The first slice of loss the fund absorbs for you over its outcome period, stated on the reference index. A 15% buffer means the index can fall 15% before you take any of it.
Cap
The most the fund can return over the period, however far the index rises. It is the price paid for the buffer.
Outcome period
The window the buffer and cap apply over, usually a year. Both are set at the start and only hold if you are there for the whole of it.
Reset
The day one outcome period ends and the next begins, with a fresh buffer and a fresh cap struck at that day’s level.
Protection left
The part of the buffer still below today’s index level. A buffer bought mid-period is not the full buffer; this is what is left of it.
