      continue to increase even when no further increases can be made to the borrower’s
      interest rate. ARM Flex® ARM MBS pools that provide interest accruals at a weighted-average
      pool accrual rate (which is developed by using either a ﬁxed MBS margin or a

      will not increase on any change date in which the interest rate cap limits the
      interest rate that is charged to the borrower. ARM loan conversion A feature
      permissible for a mortgage loan as stated in the note or related note or addendum
