Joe and Sue Smith are entitled to title II and title XVI benefits. Joe's offset amount
            is $1250.00. Sue's offset amount is $400.00. Joe's retroactive title II benefits in
            the offset period are $1000.00. Total retroactive title II benefits due Joe are $1100.00.
            The $1250.00 in offset is first subtracted from the title II due in the offset period,
            reducing it to zero. Joe has no NCI. The remaining $250.00 reduces the retroactive
            title II due outside the offset period to zero leaving a balance of $150.00 offset
            to be collected.
         
         Sue is due $500.00 total retroactive benefits, $200.00 in the offset period and $300.00
            outside the offset period. Sue's offset amount is $400.00. The $400.00 reduces the
            title II due in the offset period to 0, and the title II due outside the offset period
            to $100.00. This $100.00 is then reduced by the $150.00 remaining offset from Joe,
            reducing Sue's NC1 to 0. The $50.00 remaining offset is excess offset and is not collected
            as an overpayment.
