    Hi all..
    Are both these formulae correct ?
    Āx:y(last survivor) = 1-delta äx:y(last survivor)

    Āx:y(last survivor) = (1+i)½ [1-däx:y] where äx:y is last survivor annuity benefit.

    I was guessing both are same but when applied to a qus., both are giving different answers, though same to 3 DPs. Could anyone please clarify?

    It is ā instead of ä in first, then it is correct too ?
