In the 4c they had $1.423m on hand and expected to spend $1.937 through Mar 31.  That means they have enough cash at that rate to last through the first week of Mar.  The last SPP was open for three weeks, so if they are announcing an SPP next week and it needs to raise any amount of meaningful cash then they will be right back against the wall to get it done.  They will be operating with literally about 5 business days to spare.
