On KRY's award, interest is calcuated at the 6-month average U.S. Dollar LIBOR + 1%, compounded annually, calculated from 13 April 2008.  In April of 2008, the 6-month avg US. Libor was 2.61%.  So add one percent to that and the interest rate should be approx 3.61% on the total award.  The award was $1.202 billion.  By my calculation, if the award is paid exactly 15 years from April 13, 2008 – on April 13, 2023, then the interest should amount to approx. $844 million.
