An individual received $150 for February 2004 and was actually due $100. The FO waives
recovery of the $50 overpayment. If the FO later finds that the amount due was really
$130, the excess payment is $20 ($150 paid - $130 due). The FO does not attempt to
collect the $20 excess payment since it has already waived recovery. The waiver of
recovery of $50 is now shown as waiver of recovery of $20, and no additional amount
is due. (If the $50 had been recovered, there would be a $30 additional amount due.)
However, if the FO determines that the amount due was $195, a $45 underpayment would
be issued.
