In the case of this most recent three out of four years when we were in a deficit, we had enough cash reserves from the $5.3 million we had made in the three or four years before that to carry us through that period of time.
As mentioned earlier, it's a cyclical business where we'll have things happen. We may have already budgeted for the following year.
To give you an example, we had budgeted for 2016, and in January, we found out that two of the operations we included in our budget were shutting down entirely, one being a potash mine in Sussex, New Brunswick, and the other one being a gypsum mine in Cape Breton. We had already included those numbers in our calculations, and they disappeared overnight. Sometimes it goes the other way, and you get some business you didn't expect to get.
We bill based on the size of vessels, so when I mentioned earlier that because the size of vessels had declined, our revenues went down while the number of assignments we had stayed the same, that's the worst-case scenario for us. We still have the work to do. We still have to have as many pilots to do it, but our revenue has dropped off the cliff. That's what really happened to us in 2015.
