Expensive is relative.

True, but the time taken is often extended. Look at Vannessa; they don't seem to be making much progress.

Direct costs are not the whole picture. The real costs include the payment of staff, overheads and interest on borrowings while the process goes on. There is always a burn rate just to exist even if everything is cut to the bone. GRZ runs a pretty lean operation, but it costs money just to open the door every morning. How much do you think KRY can prune off their overheads while the arbitration process proceeds?
