If income received is temporary, received periodically, or fluctuates substantially
from month to month, convert it to a single monthly amount based on an average of
the anticipated income for the calendar year. The fact that the actual amount of income
received by the ineligible spouse in a given month varies from the estimated average
does not mean that the determination regarding allocation to the recipient is necessarily
incorrect. As long as the estimated average is valid, treat it as though it was actually received.
