(b) Actuarial Valuations. The Board shall secure an actuarial valuation showing the cost of maintaining the plan and funds on such reserve basis and, at intervals of not to exceed five years, shall cause to be made an actuarial investigation including, but not limited to, the mortality, service and salary experience of the Plan Members and other beneficiaries and shall further cause to be made annually an actuarial valuation of the assets and liabilities of the funds.
The Board, from time to time and with the advice of the investment counsel, shall establish such an assumed rate of interest for the purpose of actuarial valuations, as in its judgment seems proper in the light of the experience and prospective earnings on the investment of the funds.
