    Exclamation Survival models : complete expectation of a life

    Why is e_0^o \neq 21 + e_{21}^o ?
    e_x^o is complete expectation of life at age x
    Using ELT15 (males) mortality table

    e_0^o = 73.413 and e_{21}^o = 53.497

    but I'm unable to conclude on that equation.

    Because the life aged 0 is not guaranteed to reach age 21.
    if you dont see the significance of this, consider what your intuition says about e_{75}^0 .

    PS: this is not a specialist actuarial forum, try defining your terms in your posts.
