1. Upon termination of employment as a police officer and actual retirement for nonduty disability a member shall receive a service retirement allowance as calculated under subsection 1 of section 86.253 if the member has attained the age of fifty-five or completed twenty years of creditable service; otherwise the member shall receive a nonduty disability retirement allowance which shall be equal to ninety percent of the member’s accrued service retirement in section 86.253, but not less than one-fourth of the member’s average final compensation; provided, however, that no such allowance shall exceed ninety percent of the member’s accrued service retirement benefit based on continuation of the member’s creditable service to the age set out in section 86.250.

2. Effective October 1, 1999, the nonduty disability retirement allowance will be increased by fifteen percent of the member’s average final compensation for each unmarried dependent child of the disabled member who is under the age of eighteen, or who, regardless of age, is totally and permanently mentally or physically disabled and incapacitated from engaging in gainful occupation sufficient to support himself or herself.

3. Any member receiving benefits pursuant to the provisions of this section immediately prior to October 1, 1999, shall upon application to the board of trustees be made, constituted, appointed and employed by the board of trustees as a special consultant on the problems of retirement, aging and other matters while the member is receiving such benefits, and upon request of the board of trustees shall give opinions in writing or orally in response to such requests as may be required. Beginning October 1, 1999, for such services as may be required, there shall be payable an additional monthly compensation of one hundred dollars or five percent of the member’s average final compensation, whichever is greater, for each unmarried dependent child of the member.

4. Any benefit payable to or for the benefit of a child or children under the age of eighteen years pursuant to the provisions of subsections 2 and 3 of this section shall continue to be paid beyond the age of eighteen years through the age of twenty-two years in those cases where the child is a full-time student at a regularly accredited college, business school, nursing school, school for technical or vocational training, or university, but such extended benefit shall cease whenever the child ceases to be a student. A college or university shall be deemed to be regularly accredited which maintains membership in good standing in a national or regional accrediting agency recognized by any state college or university.

5. No benefits pursuant to this section shall be paid to a child over eighteen years of age who is totally and permanently disabled if such child is a patient or resident of a public-supported institution, nor shall such benefits be paid unless such disability occurred prior to such child reaching the age of eighteen.
