There's the payoff simulation in the presentation by Investec, and maybe we'll put that up for this discussion, Yapi, but perhaps you can just walk us through the way you think about these payoffs and how you actually backtest this.

So firstly, we did a back test on if you had had such a share that paid off between 0 and 50 in the past compared to having had these indices at those weightings on a five-year rolling return.

Because in the case of the simulated share, you didn't take losses and losses happened.

This is from 1988 to now, 22% of the time.

Because you had the geared upside up to 50 and no losses, you would have actually outperformed the physical exposure 54% of the time.

That means that at world level, so we're not talking single shares here, we're talking at world equity as an asset class.

The cap we put at 40 is because we look at the history, even the most recent 26 years, 7.1 per annum total return for five years compounds to 40.

Thank you.
