Neither FAS 113 nor SAP 62 defines the terms reasonable or significant. Ideally, one would like to be able to substitute values for both terms. It would be much simpler if one could apply a test of an X percent chance of a loss of Y percent or greater. Such tests have been proposed, including one famously attributed to an SEC official who is said to have opined in an after lunch talk that a 10 percent chance of a 10 percent loss was sufficient to establish both reasonableness and significance. Indeed, many insurers and reinsurers still apply this 10/10" test as a benchmark for risk transfer testing.
