Q2 2018 Quarterly Anticipated Receipts, page-4

Regarding the "headwinds" part of the comment in the 4C was:

However, historical data shows two headwinds Alexium may face in 2Q. First, mattress sales tend to rise and fall with housing starts, which typically are at their lowest level during the winter months. That translates in to a 10-20% slowdown during the fall months of suppliers to the mattress brands as they prepare for the annual reduction in shipments before rising again in the next quarter.

The other part refers to Thanksgiving & Christmas.

So hoping cash receipts would be at worse 80% of the previous quarter which would be around $4.6m.
