Yes. It varies based on the types of deals we're doing. As we've said in recent years, we've really shifted largely away from consolidation plays, which really was more of an intrinsic valuation approach and return on the assets you're purchasing the way you might think. So we are very disciplined in that case, multiples of EBITDA and sales and what they might do for us. And discount in the cash flows, further on but a traditional approach to that. There aren't a lot of significant consolidation plays out there doing very small, there's a lot of $3 million, $5 million, $8 million companies with 60% of their revenues are recurring, that's the book you're buying. And there just isn't a lot of that, there is a lot of PE firms and even at couple public firms that target those. So we've really moved away from those which really employed more of the traditional return on investment approach that you're alluding to. I won't say we're not disciplined, I think we've always been disciplined and certainly lose out on some deals because of that discipline, but we've certainly I guess loosened a little bit our model on strategic acquisitions, especially smaller strategic acquisitions. So I mentioned exactly time earlier probably few of us even remember that acquisition from a number of years ago. Very small few million dollars in revenue, we bought it at a reasonable price point, but the reality is, when five years later those revenues start to accelerate and the revenues there are several times what they were acquired at, the margin starts to expand because of the scale, they've improved the competitive position of your other products in those areas like Munis and Incode. You could say it almost doesn't matter too much how much you paid for them initially. So it's a difficult thing to quantify, on the strategic side, and I would say within that. We paid $10 million for that and it's obviously our e-file -- products are worth hundreds and hundreds of millions, maybe you could argue $1 billion in segment of our total market cap. So those are the deals we're looking for and that's the way we'd look at it that five and six years out, when they hit scale, when they're growing at a good rate, when their margins are Tyler-like and then you back into what their proportionate valuation within Tyler's $8 billion market cap is, they are very, very compelling. And those are the deals we're looking for those, that's why we invest in them in those early years after we acquire them and we're looking for that return down the road.
