        (1) shall carry all pension fund assets at fair market value determined in accordance
    
with generally accepted accounting principles and accounting procedures approved by the board. Each investment initially transferred to the Fund by a transferor pension fund shall be similarly valued, except that the board may elect to place such value on any investment conditionally in which case, the amount of any later realization of such asset in cash that is in excess of or is less than the amount so credited shall be credited or charged to the account maintained for the transferor pension fund that made the transfer;
        (2) shall keep proper books of account that shall reflect at all times the value of all
    
investments held by the Fund; and
        (3) shall charge all distributions made by the Fund to or for a transferor pension fund
    
to the account maintained for that fund.
