The PC coupon is expressed as an exact decimal truncated to three decimal places. The mortgages underlying a specific ARM Giant PC may have different adjustment rates. ARM Giant PCs pay principal and interest on the 15th of each month to the holder of record as of the close of business on the last day of the month two months prior to payment.
