Description: A discussion of alternative meanings to “Best” in best estimate. When one is trying to estimate a result that is normally distributed, the mean, median and mode will all equal one another. However if the results are not normally distributed, different variance metrics will result in different “best” estimates. When different parts of a financial statement use different criteria for measuring best estimates and different processes for handling variances, the results can be volatile, unpredictable and perhaps unreasonable.

Description: The article described two methods for calculating the benefit ratio described in AICPA Standard of Practice SOP 03-1. Method 1 calculates the benefit ratio as the quotient of the expectation of A and the expectation of B where A is benefits and B is assessments. Method 2 calculates the benefit ratio as the expectation of the quotient of A and B.
