53.10. The adjusted pensionable salary of an employee to whom section 53.11 does not apply and who simultaneously holds more than one pensionable employment under the plan in a year is the aggregate of the adjusted pensionable salaries computed under sections 53.7 or 53.8 and 53.9 for each employment if the total service credited in respect of such employments is less than or equal to one year.
If the total service credited in respect of the pensionable employments held by the employee is reduced under section 32, the adjusted pensionable salary of the employee is equal to the total of the following amounts:
(1) the adjusted pensionable salary for each employment in respect of which service is credited in full; and
(2) the adjusted pensionable salary for the employment in respect of which service is credited in part, multiplied by the service credited in respect of that employment over the service accumulated in such employment.
