Unless there are hidden interests to be paid it is always good to pay off loans.
Explanation:
Loans can accumulate a high tax rate for the person or the firm that has taken the loan and can and should be written off as soon as enough assets are accumulated to form a surplus and are not bound to the firm's overall growth capital.
This does not seem to be the case here as a hefty sum is simply leftover unused by the firm in terms of assets so they should be using it to write off their loans as fast as they can so as to be free of the interests and liabilities.
