How to write return objective for Individual IPS into, test, difficulty, statements, objective

I'm having difficulty figuring out how to write the return objective for individuals for IPS statements.

It seems like this has been on the test every year and I am not good at writing it.

I can usually come up with the return required but I can't seem to write out the return objective statement. Usually I say something along the lines of the following:

Achieve an after-tax return that preserves capital in relation to inflation and takes into consideration the constraints of the portfolio.

This seems to general/crappy to me. Anyone got a better method?
