The Attribution tab determines the benefit assigned through the valuation date, the benefit added during the next year, and the component funding period used for Entry Age Normal. Attribution is stored separately for each benefit component.
PUC projects the benefit payable at a future decrement date, then attributes a portion of that projected benefit through the valuation date and through the next valuation anniversary.
Accrual Proration - Formula — Multiplies the benefit projected to each decrement date by the Base Formula result at the valuation date divided by its result at the decrement date. The ratio is capped at 1.
Accrual Proration - Components — Determines the rate for each Formula Derived Item in the Benefit Formula at the valuation date and applies that rate to the item’s Benefit Base projected to each decrement date. The one-year change in the component result supports normal cost.
Each Formula Derived Item can define its optional Benefit Base on the Advanced screen.
Linear using Service Definition — Attributes the projected benefit uniformly across each year of the participant’s selected service. The valuation-date service is compared with service at the projected decrement date, and the ratio is capped at 1.
Service Definition — Supplies the component attribution service when Linear using Service Definition is selected.
This is a component-specific selection; the planwide Participation, Credited, and Vesting Service checkboxes do not select it automatically.
Base Formula — Supplies the cumulative accrual measure used by Accrual Proration - Formula.
If the valuation-date result is zero, the decrement-date result is used so the projected benefit is fully attributed.
Do not allow benefit to drop below unit credit benefit — Uses the greater of the PUC and UC attributed benefits separately at the valuation date and next valuation anniversary.
Set benefit equal to unit credit benefit — Replaces the PUC attributed benefit with the UC attributed benefit at both dates. If both comparison checkboxes are selected, this equality rule takes precedence.
UC develops the benefit attributed through the valuation date and again through the next valuation anniversary. The difference is the benefit increment used for UC normal cost.
Accrual Proration - Formula — Evaluates the Benefit Formula at the valuation date and next valuation anniversary. The difference between those results supports normal cost.
Accrual Proration - Components — Determines the rate for each Formula Derived Item in the Benefit Formula at the valuation date and applies that rate to the item’s Benefit Base using its configured Unit Credit date treatment. The one-year change in the component result supports normal cost.
Each Formula Derived Item can define its optional Benefit Base on the Advanced screen.
Linear using Service Definition — Attributes the accrued benefit as of the valuation date uniformly across each year of the participant’s selected service.
Service Definition — Supplies the component attribution service when Linear using Service Definition is selected.
This selection is independent of the planwide Participation, Credited, and Vesting Service designations.
EAN develops a funding period separately for each benefit component. The Attribution tab selects the end of that period and, when needed, a Service Definition used to derive its start.
Attribution Stop Date — Final decrement date — Ends the component funding period with the final projected decrement year in which the component produces a benefit.
Attribution Stop Date — Final retirement date — Ends the component funding period at the first future retirement date at which retirement becomes certain.
Benefit Eligibility — Selects an EAN Service Definition. With no selection, the funding start is based on date of hire. A selected service can recognize a different service base, including prior or reciprocal service, and its stop date can cap the component funding period.
This field does not replace the component Filter Formula, Benefit Start Date, or Benefit End Date on the Basic tab.
Level-percentage-of-pay EAN develops the present value of expected salary over the component funding period. The Average Earnings Definition selected for valuation supplies current earnings, while Sponsor Reported Amount assumptions project those earnings forward using the applicable fixed rate or Salary Scale Table.
Ignore earnings prior to current year when determining PVFS at Entry Age replaces earlier stored earnings in the entry-age PVFS calculation with current earnings projected backward using the salary scale. It does not replace the earnings history used by the benefit formula.
