Monthly Average Income
Section 240.850 Monthly
Average Income
Income to be received on a
monthly basis during the twelve month period is to be added to the total amount
of income received during the previous twelve months from irregular (other than

amount of income thus determined is to be divided by twelve to arrive at the
monthly average.
