Accident, sickness and unemployment insurance (sometimes referred to as A.S.R. - accident, sickness and redundancy insurance). This is an insurance policy, which is taken out by the borrower and protects against the borrower being unable to work for the stated reasons. The ASU policy will usually pay a percentage of the normal monthly mortgage repayment (plus insurance) if the borrower is unable to work due to accident/sickness or unemployment/redundancy. These payments will normally only be made for a limited period of time - typically 6/12 months or until the borrower returns to work. The terms of these policies and the cost vary considerably from company to company.
