(e) “Experience study” means a report providing experience data and an actuarial analysis of the adequacy of the actuarial assumptions on which actuarial valuations are based.

(f) “Actuarial value of assets” means the market value of all assets as of the preceding June 30, reduced by:

Subd. 8.Actuarial assumptions.

(a) The actuarial valuation must use the applicable following investment return assumption:

(b) The actuarial valuation for each of the covered retirement plans listed in section 356.415, subdivision 2, and the St. Paul Teachers Retirement Fund Association must take into account the postretirement adjustment rate or rates applicable to the plan as specified in section 354A.29, subdivision 7, or 356.415, whichever applies.

(c) The actuarial valuation must use the applicable salary increase and payroll growth assumptions found in the appendix to the standards for actuarial work adopted by the Legislative Commission on Pensions and Retirement pursuant to section 3.85, subdivision 10. The appendix must be updated whenever new assumptions have been approved or deemed approved under subdivision 18.

(d) The assumptions set forth in the appendix to the standards for actuarial work continue to apply, unless a different salary assumption or a different payroll increase assumption:

(1) has been proposed by the governing board of the applicable retirement plan;

(2) is accompanied by the concurring recommendation of the actuary retained under section 356.214, subdivision 1, if applicable, or by the approved actuary preparing the most recent actuarial valuation report if section 356.214 does not apply; and

(3) has been approved or deemed approved under subdivision 18.

Subd. 9.Other assumptions.

(a) Each plan’s actuarial valuation must use assumptions concerning base mortality rates, disability, retirement, withdrawal, retirement age, and any other relevant demographic or economic factor. These assumptions must be set at levels consistent with those determined in the most recent quadrennial experience study completed under subdivision 16, if required, or as recommended by the plan’s approved actuary, if a quadrennial experience study is not required.

(b) The actuarial valuation may use an assumption concerning future mortality improvement. This assumption may be set at levels consistent with those determined in the most recent mortality improvement scale published by the Society of Actuaries or as otherwise recommended by the plan’s approved actuary.

(c) The actuarial valuation must contain an exhibit indicating the actuarial assumptions used in preparing the valuation report.

Subd. 10.Public sector accounting disclosure information.

The actuarial valuation must contain those actuarial calculations that are necessary to allow the retirement plan administration or participating employing units to prepare the pension-related portions of annual financial reporting that meet generally accepted accounting principles for the public sector.

Subd. 11.Amortization contributions.

(a) In addition to the exhibit indicating the level normal cost, the actuarial valuation of the retirement plan must contain an exhibit for financial reporting purposes indicating the additional annual contribution sufficient to amortize the unfunded actuarial accrued liability and must contain an exhibit indicating the additional contribution sufficient to amortize the unfunded actuarial accrued liability. For the retirement plans listed in subdivision 8, paragraph (a), but excluding the legislators retirement plan, the Bloomington Fire Department Relief Association, and the local monthly benefit volunteer firefighter relief associations, the additional contribution must be calculated on a level percentage of covered payroll basis by the established date for full funding in effect when the valuation is prepared, assuming annual payroll growth at the applicable percentage rate set forth in the appendix described in subdivision 8, paragraph (c). For the legislators retirement plan, the additional annual contribution must be calculated on a level annual dollar amount basis.

(b) For any retirement plan other than a retirement plan governed by paragraph (d), (e), (f), (g), (h), (i), or (j), if there has not been a change in the actuarial assumptions used for calculating the actuarial accrued liability of the fund, a change in the benefit plan governing annuities and benefits payable from the fund, a change in the actuarial cost method used in calculating the actuarial accrued liability of all or a portion of the fund, or a combination of the three, which change or changes by itself or by themselves without inclusion of any other items of increase or decrease produce a net increase in the unfunded actuarial accrued liability of the fund, the established date for full funding is the first actuarial valuation date occurring after June 1, 2020.

(c) For any retirement plan, if there has been a change in any or all of the actuarial assumptions used for calculating the actuarial accrued liability of the fund, a change in the benefit plan governing annuities and benefits payable from the fund, a change in the actuarial cost method used in calculating the actuarial accrued liability of all or a portion of the fund, or a combination of the three, and the change or changes, by itself or by themselves and without inclusion of any other items of increase or decrease, produce a net increase in the unfunded actuarial accrued liability in the fund, the established date for full funding must be determined using the following procedure:

(i) the unfunded actuarial accrued liability of the fund must be determined in accordance with the plan provisions governing annuities and retirement benefits and the actuarial assumptions in effect before an applicable change;

(ii) the level annual dollar contribution or level percentage, whichever is applicable, needed to amortize the unfunded actuarial accrued liability amount determined under item (i) by the established date for full funding in effect before the change must be calculated using the investment return assumption specified in subdivision 8 in effect before the change;

(iii) the unfunded actuarial accrued liability of the fund must be determined in accordance with any new plan provisions governing annuities and benefits payable from the fund and any new actuarial assumptions and the remaining plan provisions governing annuities and benefits payable from the fund and actuarial assumptions in effect before the change;

(iv) the level annual dollar contribution or level percentage, whichever is applicable, needed to amortize the difference between the unfunded actuarial accrued liability amount calculated under item (i) and the unfunded actuarial accrued liability amount calculated under item (iii) over a period of 30 years from the end of the plan year in which the applicable change is effective must be calculated using the applicable investment return assumption specified in subdivision 8 in effect after any applicable change;

(v) the level annual dollar or level percentage amortization contribution under item (iv) must be added to the level annual dollar amortization contribution or level percentage calculated under item (ii);

(vi) the period in which the unfunded actuarial accrued liability amount determined in item (iii) is amortized by the total level annual dollar or level percentage amortization contribution computed under item (v) must be calculated using the investment return assumption specified in subdivision 8 in effect after any applicable change, rounded to the nearest integral number of years, but not to exceed 30 years from the end of the plan year in which the determination of the established date for full funding using the procedure set forth in this clause is made and not to be less than the period of years beginning in the plan year in which the determination of the established date for full funding using the procedure set forth in this clause is made and ending by the date for full funding in effect before the change; and

(vii) the period determined under item (vi) must be added to the date as of which the actuarial valuation was prepared and the date obtained is the new established date for full funding.

(d) For the general employees retirement plan of the Public Employees Retirement Association, the established date for full funding is June 30, 2048.

(e) For the Teachers Retirement Association, the established date for full funding is June 30, 2048, through June 30, 2025. Beginning July 1, 2025, the established date for full funding is June 30, 2053.

Subd. 12.Actuarial gains and losses.

The actuarial valuation must contain an exhibit consisting of an analysis by the actuary explaining the net increase or decrease in the unfunded actuarial accrued liability since the last valuation. The explanation must subdivide the net increase or decrease in the unfunded actuarial accrued liability into at least the following parts:

(1) increases or decreases in the unfunded actuarial accrued liability because of changes in benefits;

(2) increases and decreases in the unfunded actuarial accrued liability because of changes in actuarial assumptions;

(3) increases or decreases in the unfunded actuarial accrued liability attributable to actuarial gains or losses resulting from any experience deviations from the assumptions on which the valuation is based, as follows:

(i) actual investment earnings;

(ii) actual postretirement mortality rates;

(iii) actual salary increase rates; and

(iv) the remainder of the increase or decrease not attributable to any separate source;

(4) increases or decreases in unfunded actuarial accrued liability because of other reasons, including the effect of any amortization contribution paid or additional amortization contribution previously calculated but unpaid; and
