Yeah, thanks for that - gross margin guided to 47.5 to 48.5 percent from 49.3, memory the primary driver. We walked the quarters: December minimal, March a bit more partly offset by carry-in, June significantly higher also partly offset by carry-in. Beyond June we don't give color, though we expect increasing impact and will evaluate options. We're a large buyer on the cost-taker side and absorb the hit. Thank you.
