If   the city contributes an additional amount under this subsection,   the board's actuary shall create a new schedule of city legacy   contribution amounts that reflects payment of the additional   contribution.          (c)  The city and the board of trustees may agree on a written   transition plan for resetting the corridor midpoint, member   contribution rates, or employer contribution rates:                (1)  if at any time the funded ratio of the fund is   equal to or greater than 100 percent; or                (2)  for any calendar year after the payoff year of the   legacy liability.          (d)  The board of trustees may, by rule, adopt actuarial   principles other than those required under this section, provided   the actuarial principles:                (1)  are consistent with actuarial standards of   practice;                (2)  are approved by the retirement board's actuary;   and                (3)  do not operate to change the city legacy   contribution amount.          SECTION 26.  Article 10, Chapter 183 (S.B.
