An aggregate adjustment is needed when your lowest balance during a twelve-month cycle exceeds your impound account cushion. Your impound account cushion consists of your monthly amount of impounds, excluding monthly Mortgage Insurance, multiplied by two.
NOTE: In some states, the cushion could be based only on the monthly amount of impounds, excluding monthly Mortgage Insurance. This is commonly known as a one-month cushion. Other states may use a zero-month cushion. Consult state laws for the particular laws that will apply to you.
