OOO – Backwardation, page-8

i understand that , but do they vary the funds used to sign the contracts ? , would they control the amount bought in the contract if they knew they would lose money, surely they woukd have some safe guards and even forgo buying. it would not make sense if they lose all their cash in the funds. Do they then do a CR or finance from a lender. i do note the other beta ETFs has made some losses, even OOO has lost money in previous years.
