[GNC] Pension Fund

[rsbrux]

I had created a couple of accounts to track the capital of (and 
contributions to) pension funds for myself and my wife.  Now we are 
drawing pensions from those funds, but cannot calculate our benefits as 
a simple draw-down of the capital.  I don't want or need the capital to 
appear in our accounting any longer.  The only information I could find 
in the GC documentation about pensions pertains to U.S. tax reporting, 
but this is not relevant for me. What is the correct way to handle (i.e. 
zero out) these accounts?
