Number and average benefit shown earlier.

Historical average number of months of retroactivity based on SSA administrative records. Future months of retroactivity projected based on historical trend.

Benefit increase factor computed as 1 divided by sum of (a) 1, and (b) general benefit increase occurring in that period times number of months for which that increase did not apply divided by 12 (for years) or 3 (for quarters).

All other factors computed historically by dividing (a) non-current-payment benefits by (b) number of awards times average benefit times average number of months of retroactivity times benefit increase factor.

Historical total non-current-payment benefits computed by subtracting current-payment benefits for disabled workers, spouses, and children (shown earlier) from total benefits from Treasury Statement of Account. Historical non-current-payment benefits for disabled workers, spouses, and children prepared by Office of the Chief Actuary. Future non-current-payment benefits for disabled workers computed as number of awards times average benefit times average number of months of retroactivity times benefit increase factor times all other factors. Future non-current-payment benefits for spouses or children of disabled workers computed by applying corresponding ratio to amount for disabled workers.

Historical ratios of amount for spouses or children of disabled workers to amount for disabled workers computed by dividing corresponding figures. Future ratios projected based on historical trend.

Total amount is sum of non-current-payment benefits to disabled workers and spouses and children of disabled workers.

Note: Future estimates based on 2001 Trustees Report intermediate set of assumptions.
