(a) make calls on all or any of the contributories for the time being on the list of the contributories, to the extent of their liability, for payment of any money which the Court considers necessary to satisfy the debts and liabilities of the company, and the costs, charges and expenses of winding up, and for the adjustment of the rights of the contributories among themselves ; and
