Yeah, hey, David. I guess, I mean, looking at those two individual buckets into revenue, EBITDA, and cash. So, perhaps I can take on reverse order. So cash, I think as I said in one of the previous answers $25 million less just because of the exchange rate for based on the level of cash we've got in the business. So $150 million that we've imported this quarter had we remained at 1.35 would have been SERCA $175 million. And you can see that in the bottom of the cash flow, given where exchange rates are. I guess you can kind of do the math on that bit. I mean the better said about revenues and EBITDA is the EBITDA is far less impacted by revenues, because inevitably, there are some costs within our P&L that are dollar denominated, and therefore don't suffer any foreign exchange mix on that. So it's relatively minimal impact with our EBITDA revenues. Obviously, we've seen it this year, we've seen a reduction, but one of the I guess nuances, David, and why are you keen to not only let exchange rate settles is actually the mix of our revenues or how much of your dollar denominated revenues and non-dollar denominated revenues? I mean, of course, with this card was strong in the U.S., I think 30% of our revenues are our U.S. related. And that's probably like to go up as in Q4, and Q1, but obviously dropped significantly in Q2, and Q3 with a quieter U.S. sports calendar. So that also has a significant impact. What I would say, David, is just to reiterate, really, what Robin has said is that, at our guidance rate we are confident with the underlying performance of the business at 430 to 440. And we're likely to update that view purely from an FX example probably early in the new year.
