Look, obviously, as we said, we previously told you that we tried to get you off this quarterly book to bill going forward. We made an exception by the way last quarter, because we feel it's appropriate once in a while to clarify the numbers and we thought we had given you enough points that that enables you then to understand what it is in any given quarter and also it was focused under the method since the merger and we thought it was appropriate to do so. Now, you're right, FX can also skew the number. And it's - I have to tell you, it's not simple math when you look at the FX implications, simply because every quarter is a different set of FX numbers. And then we also revalue the backlog at the end of the quarter, where in fact the revenue is the average FX every single day during the quarter. So the numbers are hard to interpret per se in a quarter. And the trend is more important. Now, if you do simple match on the reported numbers, okay, that you do the - you take the end-of-quarter backlog minus last-year backlog, and adjust for revenue, then the math gives you 1.35 book-to-bill in the quarter, that thus include FX. And I'll tell you now, it's what it is, but that in a sense reflects what is in the numbers. That if you assume that FX are not going to change at all going forward, then that's what you have in the backlog in terms of understanding the future of the business, that's about 1.35 for the quarter. Now, if you want to look at comparisons across quarters we believe that you should look at the different numbers we gave you in the past. And if you do that and you look at the numbers this quarter in terms of progression you probably going to calculate 1.25. Now, neither so - but the real number, to answer your question, is in between that 1.25 and 1.35, closer to the 1.25 as you suggested, for the quarter on a - if we take out all FX from every single number. So that enables you to compare the quarters in a clean manner as best as we can do. Okay, so somewhere between the 1.25 and the 1.35. So you are - yeah, it's your question, you said 1.26, the answer is, yeah, you're in the ZIP code. Now, you also asked about acquisition. I told you TKL was, yeah, the TKL acquisition was largely what affected those acquisition contribution in the quarter for the R&D Solutions business, and of course, it is in the backlog.
