495—12.1(97B) General.
	12.1(1) Formula benefit versus money purchase benefit. If a member is vested by years of service credit in IPERS, a monthly payment allowance will be paid in accordance with the formulas set forth in Iowa Code sections 97B.49A through 97B.49I, the applicable paragraphs of this chapter, and the option the member elects pursuant to Iowa Code section 97B.51(1). IPERS shall determine on the applicable forms which designated fractions of a member’s monthly retirement allowance payable to contingent annuitants shall be provided as options under Iowa Code section 97B.51(1). Any option elected by a member under Iowa Code section 97B.51(1) must comply with the requirements of the Internal Revenue Code that apply to governmental pension plans, including but not limited to Internal Revenue Code Section 401(a)(9). If a member is not vested by years of service credit in IPERS, the benefit receivable will be computed on a money purchase basis, with reference to annuity tables used by IPERS in accordance with the member’s age and option choice.
	12.1(2) Reduction for early retirement for regular class members.
	a. 	Effective July 1, 1988, through December 31, 2000, a member’s benefit formula will be reduced by .25 percent for each month the member’s retirement precedes the normal retirement date, as defined in Iowa Code section 97B.45 excluding section 97B.45(4). The following are situations in which a member is considered to be taking early retirement:
	(1)	If a member has not attained the age of 65 in the member’s first month of entitlement and has less than 20 years of service; or
	(2)	If a member has not attained the age of 62 in the month of the member’s retirement and has 20 years of service.
	b. 	Effective July 1, 1997, a member shall be eligible to receive monthly retirement benefits with no age reduction effective the first of the month in which the member’s age on the last birthday and the member’s years of service equal or exceed 88, provided that the member is at least the age of 55.
	c. 	Effective July 1, 1991, a member qualifying for early retirement due to disability under Iowa Code section 97B.50 shall not be subject to a reduction in benefits due to age.
	d. 	If a member retires with at least 20 years of service but has not attained the age of 62, the age reduction shall be calculated by deducting .25 percent per month for each month that the first month of entitlement precedes the month in which the member attains the age of 62. If a member retires with less than 20 years of service, the age reduction shall be calculated by deducting .25 percent per month for each month that the first month of entitlement precedes the month in which the member attains the age of 65.
	e. 	Effective January 1, 2001, the age reduction shall be calculated by deducting .25 percent per month for each month that the first month of entitlement precedes the earliest possible normal retirement date for that member based on the age and years of service at the member’s actual retirement.
	f. 	For the portion of the member’s retirement allowance based on service through June 30, 2012, the early retirement reduction shall be calculated as provided in paragraphs 12.1(2)“a” through “e.” For the portion of the retirement allowance based on years of service beginning July 1, 2012, and later, the member’s early retirement reduction shall be one-half of one percent for each month that the early retirement precedes the date the member attains age 65.
	12.1(3) Early retirement date for regular class members. A member’s early retirement date shall be the first day of the month of the fifty-fifth birthday or any following month before the normal retirement date, provided that date is after the member’s termination date.
	12.1(4) Benefit formulas for members retiring on or after July 1, 2012.
	a. 	For each member retiring on or after July 1, 2012, who is vested by service, the monthly benefit will be equal to one-twelfth of an amount equal to 60 percent of the final average covered wage multiplied by a fraction of years of service.
	b. 	For all active and inactive vested members, the monthly retirement allowance shall be determined on the basis of the formula in effect on the date of the member’s retirement. If the member takes early retirement, the benefit shall be adjusted as provided in subrule 12.1(2).
	c. 	 In addition to the 60 percent multiplier identified above, regular class members who retire with years of service in excess of 30 years shall have the percentage multiplier increased by .25 percent for each quarter of a year in excess of 30, not to exceed an increase of 5 percent.
	d. 	In addition to the 60 percent multiplier identified above, protection occupation members, sheriffs, and deputy sheriffs who retire with years of service in excess of 22 years shall have the percentage multiplier increased by .375 percent for each quarter of a year in excess of 22, not to exceed an increase of 12 percent.
	e. 	Regular service does not count as “eligible service” in determining a special service member’s applicable percentage.
	12.1(5) Average covered wages for special service members and for wages of regular class members prior to July 2012.
	a. 	“Three-year average covered wage” means a member’s covered calendar year wages averaged for the highest three years of the member’s service. However, for the member’s final year of wages, IPERS may determine the wages for the third year by computing the final quarter or quarters of wages to complete the year. The computed year will be created when the final quarter or quarters reported are combined with a computed average quarter to complete the last year. The value of this average quarter will be computed by selecting the highest covered wage year not used in the computation of the three high years and dividing the covered salary by four quarters. This value will be combined with the final quarter or quarters to complete a full calendar year. If the member’s final quarter of wages will reduce the three-year average covered wage, it can be dropped from the computation. However, if the covered wages for that quarter are dropped, the service credit for that quarter will be forfeited as well. If the final quarter is the first quarter of a calendar year, those wages must be used in order to give the member a computed year. The computed year wages shall not exceed the Internal Revenue Service maximum covered wage in effect for that calendar year. Furthermore, the computed year shall not exceed the member’s highest actual calendar year of covered wages by more than 3 percent. Effective July 1, 2007, a member’s high three-year average wage shall be the greater of (1) the member’s high three-year average covered wage based on covered wages reported through June 30, 2007; or (2) the member’s high three-year average covered wage after application of the antispiking control as described in paragraph 12.1(5)“b” below.
	b. 	Antispiking limit on the growth of a member’s high three-year average.
	(1)	Selection of the control year shall give highest priority to calendar years of wages in which there are four quarters of service credit for wages on file not used in the high three-year average wage calculation. For example, if the member receives $20,000 of wages for a calendar year with four quarters of service credit for wages, and the member also has received $30,000 of wages for a calendar year with three quarters of service credit for wages, the control year selection process shall give preference to the calendar year with $20,000 of reported wages.
	(2)	If there is a calendar year of covered wages outside the high three-year average wage calculation that has four quarters, but the covered wages for that year are less than the covered wages for the fourth highest calendar year of covered wages, and that fourth highest calendar year of covered wages does not have four quarters of service credit for wages, the control year will be the lowest of the high three calendar years of wages with service credits for wages in all four quarters being used in the high three-year average wage calculation.
	(3)	“Service credit for wages” means service credit recorded for:
	1.	Quarters in which the member receives covered wages from covered employment.
	2.	Quarters in which the member is credited with covered wages due to a military leave.
	3.	Quarters in which the member would have had covered wages but for the application of the IRS covered wage limitations.
	4.	Quarters in which an employee of a nine-month institution receives service credit for a qualifying leave of absence under 495—subrule 7.1(2).
	5.	Quarters in which a legislator, legislative employee, or elected official receives service credit for employment.
	(4)	If none of the calendar years of wages that fall outside of the high three-year average wage calculation have service credit for wages reported in all four quarters, the control year will then be the lowest of the high three calendar years of wages with service credit for wages in all four quarters being used in the high three-year average wage calculation.
	(5)	If none of the wage years used in the high three-year average wage calculation have service credits for wages reported in all four quarters, the control year will then revert to the highest calendar year of wages not included in the high three-year average wage calculation, regardless of whether there are fewer than four quarters with service credits for wages on file.
	(6)	For high three-year average wage calculations that utilize the computed year, the control year may be the calendar year from which the “average quarters” used in the computed year are drawn. However, the control year cannot be the computed year, as the computed year will never be a calendar year with service credit for wages in all four quarters.
	c. 	Effective July 1, 2012, a nonvested regular class member’s average covered wage shall be the member’s five-year average covered wage calculated as provided in Iowa Code section 97B.1A(10A)“a.”
	d. 	Effective July 1, 2012, for regular class members vested as of June 30, 2012, the member’s average covered wage shall be the greater of the member’s three-year average covered wage calculated as provided under paragraphs 12.1(5)“a” and “b,” or the member’s five-year average covered wage calculated as provided in Iowa Code section 97B.1A(10A)“a.” The “five-year average covered wage” means a member’s covered calendar year wages averaged for the highest five years of the member’s service. However, in the member’s final year of wages, IPERS may determine the wages for the fifth year by computing the final quarter or quarters of wages to complete the year. The computed year wages shall not exceed the Internal Revenue Service maximum covered wage in effect for that calendar year. Furthermore, the computed year shall not exceed the member’s highest actual calendar year of covered wages by more than 3 percent. A full fifth year will be created when the final quarter or quarters reported are combined with a computed average quarter to complete the last year. The value of this average quarter will be computed by selecting the highest covered wage year not used in the computation of the five high years and dividing the covered salary by four quarters. This value will be combined with the final quarter or quarters of wages to complete a full calendar year. If the member’s final quarter of wages will reduce the five-year average covered wage, it can be dropped from the computation. However, if the covered wages for that quarter are dropped, the service credit for that quarter will be forfeited as well. If the final quarter is the first quarter of a calendar year, those wages must be used in order to give the member a computed year. The five-year average covered wage cannot exceed the highest Internal Revenue Service maximum covered wages in effect during the member’s service. In addition, the average five-year salary is restricted to an antispiking limit of 134 percent of the highest sixth year of wages.
