It would not be standard accounting practise to have part owned subsidiaries which are separate companies sharing the same cash on each others balance sheet.

LIS energy, for example had just over $28M as of 31 Dec in cash on their balance sheet.
PPK had just over $32M on theirs.

If, and I highly doubt this is the case, they shared this cash on separate balance sheets, then only $14M of LIS' cash would be owned by PPK and it should be counted as restricted cash as PPK couldn't use it without the permission of LIS
