2) Calculate the member's monthly benefit using salaries as reported, excluding that part of the member's salary that exceeds the member's salary with the same employer for the preceding year by more than 6%.

3) Subtract (a)(2) from (a)(1).

4) Multiply (a)(3) by a Monthly Benefit Factor for the member's exact age at the retirement date. The Monthly Benefit Factors are based on the actuarial assumptions of the System for life expectancy and investment return as determined by the System's actuaries pursuant to 40 ILCS 5/16-176.

5) If a member's monthly benefit is calculated pursuant to 40 ILCS 5/16-133(a), this Section will not apply.

8) If the member's benefit is reduced as a result of applying proportional reductions required by 40 ILCS 5/20-124, no employer contribution will be assessed for any salaries attributable to any reciprocal employment used in the calculation.

9) If the average salary is calculated using salary earned through employment covered by another participating system under 40 ILCS 5/20, no employer will be assessed for any salaries attributable to that employment.

10) The member's salary for any school year used to determine final average salary shall be excluded for purposes of determining the employer contribution required for salary increases in excess of 6% in any year in which the member's creditable earnings are less than 50% of the preceding year's mean salary for downstate teachers as determined by the survey of school district salaries provided in Section 2-3.103 of the School Code.
