Hi, Paul, [let me] [ph] take that. So, yes, we do intend to continue to, kind of whittle down that [indiscernible]. And we hired a very senior supply chain professional in 2022 and he's doing a lot of work in terms of optimizing our overall supply chain, okay? It's a balancing act for us, okay? So, for example, on one side, we want to reduce that [Technical Difficulty] inventory, but at the same time, given everything we've seen over the last 2 years to 3 years, in terms of supply chain challenges, we need to make sure that we've got enough protective product on hand, particularly around raw materials. In terms of other areas for write-offs, to you give you some sense, in total, we're carrying forward related inventory now probably about $1 million okay, in terms of carrying value. We sold about $0.5 million of COVID-related products in quarter four. I expect we'll do something similar in quarter one this year, right. So, in that sense, we're not holding big, big inventory values from a net basis in terms of products that are highly uncertain. And then our other inventory is concentrated in our ongoing main product areas. So, for example, associated with HIV, we obviously have the ramp up now production at TrinScreen and that's going to add some headcount production as well here in Ireland, but we'll need to increase our inventories. So, I think overall the picture might stay the same, but I think, we’ll effectively be trying to hold lower amount of inventories for every dollar revenue that we have going out the door. That makes sense for.
