In comparison with the interest assumptions in effect for the fourth quarter of 2015, these interest assumptions represent no change in the select period (the period during which the select rate (the initial rate) applies), an increase of 0.36 percent in the select rate, and a decrease of 0.03 percent in the ultimate rate (the final rate)."
