Avails are profits or proceeds, especially from the sale of property or the proceeds of an insurance policy. The latter are any amounts available to the policyholder apart from the actual proceeds of the policy, including cash, interest, dividend payments, surrender value (the amount you would receive if you sold the policy back to the insurance company) and loan value (the amount of cash you would borrow against the policy).
