Except as hereinafter provided and prior to adjustment in accordance with Section 4.06(a) and 4.07(b), the annual postponed retirement allowance payable on a lifetime basis upon retirement at a Member’s Postponed Retirement Date shall be equal to the annual normal retirement allowance to which the Member would have been entitled under Section 4.01(b) had he or she retired on his or her Normal Retirement Date, increased by an amount which is the Equivalent Actuarial Value of the monthly payments which would have been payable with respect to each month in which he or she completed less than 40 Hours of Service. Any monthly payment determined under this paragraph (b) with respect to any such month in which he or she completed less than 40 Hours of Service shall be computed as if the Member had retired on his or her Normal Retirement Date.
