If in the contract with Corica HUM has specified "no payments if you drop below required output" then Corica have not a leg to stand on, simple as that really.
Oh dear if your that worried about investing in Hum then best not to bother, as for the rest of us, we can make our own minds up, But thanks for your concern anyways , very sweet of you !
Lets see what happens then ! as long as the company keeps trading thats fine, dont want it taken over or going bang, if it keeps trading it will get back on track eventually ! be it 6 months or 2 years, it really is a rollercoaster ride this share !
