Thanks, Kevin. So I'm happy to give you a little bit of view there. So, first in terms of the depreciation and amortization, you’re right that it’s down significantly. And yes, we do use double declining balanced, which means that in general you'll see some small reductions in depreciation and amortization. In large part, MediGain sort of crossed the point in the amortization where you are always talking doubled and then you switch to the straight line for the remaining term. So you won't see as bigger decrease and again a not only as a decrease that you saw in the middle of 2017 was the amortization from the three companies we bought on the day of the IPO. And at that time we were using straight line. So those three continue through straight-line they’re fully amortized. So, you should expect to see the depreciation and amortization, slowly go down until or unless we do a major acquisition. Obviously when we buy companies, what happens is you really buying asset, but there is not a lot of tangible assets, we're not buying brick and mortars, we're not buying factory and land and inventory. So, therefore it pretty much all gets attributed to intangibles which we then amortized quickly. So, until we do something major, I wouldn't expect to see any increase in the amortization. In terms of stock-based comp, in some respects it's a little bit harder to predict, because the amount that you taking as stock-base comp, is based on the value of our common stock on days that stock were its best. So, there are restricted stock units that were granted some time ago to management, key employees, Board members, those best on particular dates. If the stock is at $4 on a day that they invest, you book a $4 expense that the stock is twice that or four times that, then that's what's you going to book. So, it's kind of hard for us to predict exactly what that number is going to look like. Again, from one perspective as the CFO, that's an accounting entry, but is not a cash entry, I'm not writing a check. So, it may effect by GAAP reported numbers, but we remove it from our non-GAAP metrics.
