If more than one type of unearned income is determined to be infrequent or irregular,
                  the first $60 of unearned income received infrequently or irregularly in a calendar
                  quarter is excluded from income. The infrequent or irregular income exclusion is applied
                  to the payment that was received first. Any remaining exclusion is applied to other
                  infrequent or irregular payments in the order in which they were received.
