Great to get some news - thanks for updating us with a call to IR.
Flow-throughs, nice but for most of us forget about them. You can't use the write-offs against normal income (e.g. wages or interest) nor can you use them against capital gains - only against business income. So unless you have a small or large business that can use the write-offs, forget about it.
It benefits us in that it brings in share buyers that might not otherwise invest, and flowing out the losses to them costs us and KXL nothing, as KXL has no income to use them for anyways.
