Syntax

LifeInsJL (CurrentAgeX, CurrentAgeY, InterestRate, MortalityTableX, MortalityTableY, [Term], [Increasing], [InsTiming])

Parameter Name

Description

CurrentAgeX

Current age of the 1st insured life 𝑥 (i.e. the age at the valuation date). May be provided as an integer, or as a fractional amount (e.g. years & months). If the age is not a whole number, the result is based on interpolation on results at whole ages.

CurrentAgeY

Current age of the 2nd insured life 𝑦 (i.e. the age at the valuation date). May be provided as an integer, or as a fractional amount (e.g. years & months). If the age is not a whole number, the result is based on interpolation on results at whole ages.

InterestRate

The interest rate(s) to discount future payments to calculate the present value.

·       Interest may be entered as a rate, e.g. 5% or .05; or 3 segments "i1/i2/i3". Other interest rate definitions that are available for annuities are not available for insurance.

·       Note: A value that is greater than 25% (i.e. 0.25) will be divided by 100; e.g. if you enter 2.75 it will be treated as .0275 or 2.75%.

MortalityTableX

Mortality table definition text string for the 1st insured life 𝑥.

MortalityTableY
