(2) Alternative determination of retired pay base using uncapped rates of basic pay as of december 31, 2014 .— For a determination in accordance with this paragraph, the amount of an officer’s retired pay base shall be determined by using the rate of basic pay provided as of December 31, 2014 , for that officer’s grade as of that date for purposes of basic pay, with that officer’s years of service creditable as of that date for purposes of basic pay, and without regard to any reduction under section 203(a)(2) of title 37 . (3) Exception for officer retired in a lower grade .— In a case in which the retired grade of the officer is lower than the grade in which the officer was serving on December 31, 2014 , paragraph (2) shall be applied as if the officer was serving on that date in the officer’s retired grade.
