The cash sweep or debt waterfall can be quite complicated and tricky. There can be switches all over the place and lots of different tranches of debt that seem to be working against each other, but at its heart there are some core principles that we usually see. The top of a cash sweep is going to be some kind of pile of cash. In this case, it's cash flow available for debt service. That's cash flow just from this year available for debt service, and it's calculated by taking EBITDA and then any other operating or investing cash flows, for instance, your tax expense and your CapEx. From that, we then need to take off any interest payments, and mandatory debt repayments. We can't avoid them, so they have to go. Hopefully, we've still got some of our cash flow left over but we want to try and bolster that cash pile, so we add onto it any beginning cash any cash left over from the previous year, but then we subtract any minimum cash that we want to hold onto. This big pile of cash is now available to pay off other kinds of debts. And we call it cash available for the revolving credit facility RCF, refinancing facility and the sweep. So let's start paying those items off. We subtract out the revolving credit facility if at all possible. If we were a negative cash position, then at this point we would issue a revolver. If the revolver gets maxed out, then we will draw down on that refinancing facility. However, if we do still have some cash available that's when we can get into the sweep. We can start making accelerated repayments of all the types of debt that allow it.
