For liability calculations, Age Difference Tables reflect the number of years by which husbands are expected to be older than wives.

See also Payment Form Definitions – pension modes, Inactive Payment Form - pension modes and Post-decrement Death Benefit payment form (e.g., U.S. REA benefit) , which include variation based on the age of the spouse, and the Other Valuation Parameters topic of Valuation Assumptions.

Varying age setbacks are entered in a table with an interface that permits variation by age and/or sex. If age differences are constant, then it is not necessary to create age difference tables. Note that inputs are expected to be the number of years that husbands are assumed to be older than their wives (and, in most cases, would be positive). In addition, integer values are required.

ProVal looks up table values based on the participant’s age, as defined by the date of birth (or attained age) parameter of the Census Specifications. Age for table lookups is always computed as a whole number (not a fraction). For details, see Active Data and Inactive Data - pension modes. For a Payment Form whose commencement is deferred (i.e., payments do not start immediately upon decrement), ProVal will look up values using age at decrement, age at commencement or age at death, depending on the setting of the Beneficiary determined parameter of the Payment Form.
