Annuity and term assurance functions...

... I've clearly forgotten everything I learnt in CT1/5 and can't remember how to calculate even the easiest functions for assignment X4.

Can anyone remind me of:

A x:n

..
a x:n

(the n in each case has a ¬ around it)

Having a minor brain freeze!!

Thanks,

Steph

 

I think you'll find them in the formula book.

 

Not as far as I can see?! Only the conversion formulas are there?

 

Ax:n = 1- delta * ax:n
You can do it from scratch, ie add probabilities and discount factors.

or ax:n = ax - n|a(x+n)

 

And don't forget pages 100/1 and 106/7 if x and n sum to 60 or 65. Hopefully most of the questions will be like this, in the exam at least!
