System used by insurer or managing agent to record, monitor and control their total aggregate exposures by country of risk, class of business, years of exposure or other appropriate variable. For example, in the exempted classes of financial guarantee insurance Lloyd’s calls upon managing agents to run systems that enable syndicates to avoid excessive exposure to any one obligor, industrial sector, location or insured nationality, in any one obligor country. The totals are regularly monitored to ensure that any limits are not exceeded.
