15:19 Yes. Hey, Jared, it’s Mariner. I would say that utilization rates, they pop around quite a bit within one or two points one-way or the other, particularly during COVID. This is the period we're in, it’s kind of hard to really tell where it should be settling out. 15:41 From third quarter to fourth quarter [of 2020] [ph] for example it went the other way, and this quarter – these last two quarters, it went up slightly. So, I think this pandemic period is kind of hard to just come up with an adjusted number. So, it's been kind of [bouncing] [ph] around. So, I hesitate to give you what that normalized number should be right now. 16:08 Pre-covid things were bumping around 30%, you know our utilization rate is really around 30%. So, you do with that what you will, but on loan growth and payoffs and paydowns, as we have the historically we've given you a good look into the next quarter, we try not to do too much guidance beyond the coming quarter. And as really it is the pipeline for the coming quarter, it looks the strongest as it has been looking. 16:42 And I would say that fourth quarter 2021 was the best gross production quarter we've had at almost 1.4 billion in gross production. So, we're pretty [pumped] [ph] about the trajectory and the successes we’re having there. As far as payoffs and paydowns go, I think we're running in the 5% range right now, high-5s in the fourth quarter. 17:11 I think as long as rates are low, as they have been, that's going to push cap rates low and the secondary market opportunities will remain strong, obviously, we're all predicting rates to come up, that should moderate. I think that should moderate the payoffs and paydowns over 2022 as rates come up. 17:40 We'll have to see, you know, rates coming up, they're still going to be at all-time lows. I think the market is going to still be very strong even with rates coming up, but it should certainly moderate sales and paydowns.
