Gift Annuity - Planned Giving Module

We are doing an audit of our planned gifts and we wanted to reach out to others to see how you are using the PG Module for gift Annuities.  Our financial office enters in the planned gift of gift annuity and then they link the realized amount to the cash/stock "gift" that the donor used to create the annuity.  We are struggling with this.  Shouldn't the realized amount be the amount that is remaining with the donor passes away or the given time frame?  Do you track the money that supported the annuity in RE? If so, how do you add it in the module and how do you track the remainder amount when they pass away?  If you have a gift entry procedure guide that has steps, can you please share?  




Thanks in advance!
