ALLOWANCE ON DISABILITY RETIREMENT

(4) Upon retirement for disability a member shall receive
a service retirement allowance if he has attained age 60, other-
wise he shall receive a disability retirement allowance which
shall consist of:

(a) An annuity which shall be the actuarial equivalent of
his accumulated contributions at the time of retirement; and

(b) A pension which, together with his annuity, shall pro-
vide a total retirement allowance equal to ninety per centum
of one-seventieth of his average final compensation multiplied
by the number of years of his creditable service, if such retire-
ment allowance exceeds one-quarter of his average final compen-
sation; otherwise a pension which, together with his annuity,
shall provide a total retirement allowance equal to one-quarter
of his average final compensation, provided, however, that no
such allowance shall exceed ninety per centum of one-seventieth
of his average final compensation multiplied by the number of
years which would be creditable to him were his service to con-
tinue until the attainment of age 60.

RE-EXAMINATION OF BENEFICIARIES RETIRED ON ACCOUNT

OF DISABILITY

(5) Once each year during the first five years following
retirement of a member on a disability retirement allowance,
and once in every three-year period thereafter, the Board of
Trustees may, and upon his application shall, require any dis-
ability beneficiary who has not yet attained age 60 to undergo
a medical examination, such examination to be made at the
place of residence cf said beneficiary or other place mutually
agreed upon, by a physician or physicians designated by the
Board of Trustees. Should any disability beneficiary who has
not yet attained the age of 60 refuse to submit to at least one
medical examination in any such year by a physician or physi-
cians designated by the Board of Trustees, his allowance may
be discontinued until his withdrawal of such refusal, and should
his refusal continue for one year, all his rights in and to his
pension may be revoked by the Board of Trustees.

(a) Should the Medical Board report and certify to the
Board of Trustees that such disability beneficiary is engaged in
or is able to engage in a gainful occupation paying more than
the difference between his retirement allowance and Ms average
final compensation, and should the Board of Trustees concur in
such report then the amount of his pension shall be reduced to
an amount which together with his annuity and the amount
earnable by him, shall equal the amount of his average final
