Illinois Statutes Chapter 40. Pensions § 5/11-154. Amount of child's annuity

(1) If the combined annuities for the widow and children of an employee whose death resulted from injury incurred in the performance of duty, or for the children where a widow does not exist, exceed 70% of the employee's final monthly salary, the annuity for each child shall be reduced pro rata so that the combined annuities for the family shall not exceed such limitation;

(2) For the family of an employee whose death is the result of any cause other than injury incurred in the performance of duty, in which the combined annuities for the family exceed 60% of the employee's final monthly salary, the annuity for each child shall be reduced pro rata so that the combined annuities for the family shall not exceed such limitation.

A child's annuity shall be paid to the parent who is providing for the child, unless another person has been appointed the child's legal guardian.

The increase in child's annuity provided by this amendatory Act of 1997 shall apply to all child's annuities being paid on or after the effective date of this amendatory Act of 1997. The limitations on the combined annuities for a family in parts (1) and (2) of this Section do not apply to families of employees who died before the effective date of this amendatory Act of 1997.
