The short notional amount on certain of our interest rate contracts with a three month duration is approximately $16.0 billion as of December 31, 2015. We assume that interest rates will not fall below zero and therefore our downside short notional exposure to loss on these contracts is $74 million (of the total $137 million disclosed in the above table) as of December 31, 2015.
