This is my amateur and simple explanation. Some Pro from the board should do it much better.

Cash on Hand is the total, liquid assets in the bank.

Working Capital is the what is actually available after subtracting committed expenses.

For example; If your cash on the acct is $100M and your purchases which you did not pay for yet are $20M , your working capital is $80M.

Your working capital will be use to pay for day to day operations, Capex and interest obligations.

In the case of the CLL the most of the Cash on the Hand are the reminder of the $600 loan and most of it is plan to be burned for the CAPEX and Interest payments. No money for ALGAR unless they will get the new financing.
