After a difficult audit of our remuneration report two years ago, where we could not reconstruct why the committee had made a particular adjustment, I introduced a one-page record for every decision. I work for a listed bank in the Nordics.
It has six fields: the decision; the formulaic outcome before any judgement; the factors considered, each with a line on what the committee concluded; the alternatives discussed and rejected; who was in the room and who withdrew; and the sentence we expect to use in disclosure.
The last field has been the most useful. Writing the disclosure sentence at the time of the decision has twice caused the committee to change its mind. Happy to hear what others record, or what you would add.
