The following topics are available under the CAS Liabilities section of funding Valuation Assumptions in U.S. Qualified mode when the "PPA and CAS" Applicable law is selected. 

Interest Rates

The Actuarial Accrued Liability interest rates topic may only be specified as a constant interest rate.

The Minimum Actuarial Liability interest rate assumption may be specified as a constant interest rate, as PPA-style segment rates, or as a spot rate curve. When specified as a spot rate curve, either rates from the Yield Curve library may be selected or variable by duration interest rates specified. Lookup buttons are available to facilitate the pasting of published PPA interest rates. Please see the documentation for the Interest Rates topic under Valuation Assumptions for more information about the different types of interest rates.

Mortality

Under the CAS Liability Mortality topic, the mortality assumptions for both the CAS Actuarial Accrued Liability and the CAS Minimum Actuarial Liability may be specified by selecting the desired mortality tables for active participants prior to decrement, and inactive and active participants after decrement separately for retired members, vested terminations, survivors & beneficiaries, and disabled members. For survivors and beneficiaries, a checkbox is available if retired member mortality is to be used prior to member death. Backdoor buttons are available to access the mortality table library. Params buttons are available to specify the service to be used to determine active mortality rates when a service-related mortality table is specified and to specify rates by coded field and/or calendar year when that option is specified. Please see the documentation for the Decrements topic under Valuation Assumptions for more information relating to mortality assumptions.

 Cost Method & Participants

Under the CAS Cost Method & Participants topic, the cost method used for the Actuarial Accrued Liability must be specified. The following four cost methods are available:

• Entry Age Normal (EAN) - Level % of salary

• Entry Age Normal (EAN) - Level dollar

• Projected Unit Credit (PUC)

• Pure Unit Credit (UC) 

When an Entry Age Normal method is chosen, the Params button allows you to specify details related to the Entry Age Normal (EAN) calculation. The EAN parameters are shared with the Actuarial Liability when an Entry Age Normal method is being run. Please see the documentation for the Actuarial Liability topic for more information regarding these parameters.

The CAS Minimum Actuarial Liability is always automatically run using the pure unit credit method, so no alternative cost method option is available.  

To exclude certain participants from the CAS liabilities, an Exclusion Field may be optionally specified from a choice list of available coded fields. Once selected, indicate which codes are to be excluded by checking the checkbox next to each such code.

Conversion Factors

Under the CAS Conversion Factors topics, interest and mortality assumptions to be used for conversion factors for each lump sum factor benefit formula component, late retirement factor, pension equity component, and optional payment form may be specified separately for the CAS Actuarial Accrued Liability and the CAS Minimum Actuarial Liability. The interest and mortality options available are the same as you would find under the regular Conversion Factors topic. Please see the Conversion Factors topic for details relating to these options.
