The individual account maintained on behalf of each participant shall be credited or debited (as the case may be) with the allocable share of such participant in the plan resulting from employer contributions (or including forfeitures as a part thereof), employee contributions and appreciation or depreciation in the value of the pension fund, as set forth herein.
A. 
The Plan Administrator shall determine, as of each annual valuation date, the net value of the pension fund and the amount of net income or net loss. In determining such value, the Plan Administrator shall value such assets at their fair market value as of the close of business on each valuation date, and the appreciation or depreciation in the value of the pension fund since the prior valuation date plus any net income (exclusive of contributions and forfeitures) or net loss and expenses incurred shall be debited or credited among the participant's accounts.
B. 
The Plan Administrator may determine the value of the pension fund or any participant account as of any reasonable interim valuation date on a reasonable basis consistent with the terms of the plan. Final reconciliation of and verification of the proper valuation shall occur as of each annual valuation date, which shall include any necessary and appropriate adjustments from any interim valuation.
As of any annual valuation date, the earnings and accretions of the pension fund attributable to investment of fund assets, reduced by losses experienced (whether or not realized) and expenses incurred since the preceding annual valuation date, shall be credited or debited to the accounts of the participants and beneficiaries who had unpaid balances in their accounts as of such annual valuation date in proportion to the balances in such accounts as of the prior valuation date, after reducing such prior valuation date balances by the amounts withdrawn by or distributed to the participant or beneficiary since such valuation date, if any. To the extent that a participant self-directs the investment of the balance of the participant's account, the crediting of investment results shall be the actual investment performance of those investments.
As of each annual valuation date, after such crediting of the valuation results to each account, contributions shall be allocated to each account pursuant to § 60-83. Any Forfeitures that arise in a given plan year shall be used to reduce the amount of employer contributions for such year pursuant to the provisions of § 60-81 hereof.
If the Plan Administrator is investing in an unallocated group annuity or investment contract, such assets shall be valued and accounts adjusted in the same manner as provided in § § 60-89 and 60-90.
The total value of a participant's account shall be determined as of each valuation date and, as soon as practical after the end of such plan year, the Plan Administrator shall convey to each participant the total value of the account as determined pursuant to this Article XVIII; provided, however, that neither the maintenance of accounts nor the allocations of contributions to accounts shall operate to vest in any participant any right or interest in or to any assets of the pension fund except as the plan specifically provides.
