97A.8  Method of financing.
  There is hereby created as a special fund, separate and apart from all other public moneys or funds of this state, the peace officers’ retirement, accident, and disability system retirement fund, hereafter called the “retirement fund”. All the assets of the system created and established by this chapter shall be credited to the retirement fund.
  1.  All moneys for the payment of all pensions and other benefits payable from contributions made by the state and from which shall be paid the lump-sum death benefits for all members payable from the said contributions shall be accumulated in the retirement fund. The refunds and benefits for all members and beneficiaries shall be payable from the retirement fund. Contributions to and payments from the retirement fund shall be as follows:
  a.  On account of each member there shall be paid annually into the retirement fund by the state of Iowa an amount equal to a certain percentage of the earnable compensation of the member to be known as the “normal contribution”. The rate percent of such contribution shall be fixed on the basis of the liabilities of the retirement system as shown by annual actuarial valuations.
  b.  (1)  On the basis of the actuarial methods and assumptions, rate of interest, and of the mortality, interest, and other tables adopted by the board of trustees, the board of trustees, upon the advice of the actuary hired by the board for that purpose, shall make each valuation required by this chapter pursuant to the requirements of section 97A.5 and shall immediately after making such valuation, determine the “normal contribution rate”. The normal contribution rate shall be the rate percent of the earnable compensation of all members equal to the rate required by the system to discharge its liabilities, stated as a percentage of the earnable compensation of all members, and reduced by the employee contribution rate provided in this subsection. However, the normal rate of contribution shall not be less than seventeen percent.
  (2)  Notwithstanding the provisions of subparagraph (1) to the contrary, the normal contribution rate shall be as follows:
  (a)  For the fiscal year beginning July 1, 2008, nineteen percent.
  (b)  For the fiscal year beginning July 1, 2009, twenty-one percent.
  (c)  For the fiscal year beginning July 1, 2010, twenty-three percent.
  (d)  For the fiscal year beginning July 1, 2011, twenty-five percent.
  (e)  For the fiscal year beginning July 1, 2012, twenty-seven percent.
  (f)  For the fiscal year beginning July 1, 2013, twenty-nine percent.
  (g)  For the fiscal year beginning July 1, 2014, thirty-one percent.
  (h)  For the fiscal year beginning July 1, 2015, thirty-three percent.

  (j)  For each fiscal year beginning on or after July 1, 2017, the lesser of thirty-seven percent or the normal contribution rate as calculated pursuant to subparagraph (1).
  c.  The total amount payable in each year to the retirement fund shall not be less than the rate percent known as the normal contribution rate of the total compensation earnable by all members during the year. However, the aggregate payment by the state shall be sufficient when combined with the amount in the retirement fund to provide the pensions and other benefits payable out of the retirement fund during the then current year.
  d.  All lump-sum death benefits on account of death in active service payable from contributions of the state shall be paid from the retirement fund.
  e.  Except as otherwise provided in paragraph “g”:
