All moneys in the funds and accounts established pursuant to this Indenture, other than the Rebate Fund, shall be invested by the Trustee or the Depositary, as the case may be, solely in Investment Securities to maximize investment income, with proper regard for the preservation of principal, subject to any Request of the Government as to such investment. All Investment Securities and any other investments acquired with moneys held hereunder shall be acquired subject to the limitations set forth in § 6.09, to the limitations as to maturities hereinafter in this Section set forth and to such additional limitations or requirements
consistent with the foregoing as may be established by Request of the Government. Moneys in the Rebate Fund shall be invested as provided in § 5.08 and in the Tax Certificate. Moneys in all funds and accounts established under this Indenture shall be invested in securities paying interest and maturing not later than the dates on which it is estimated that such moneys will be required by the Trustee or the Depositary. All interest and other profit derived from such investments shall be deposited at least monthly in the Revenue Fund, except that interest and other profit derived from the investment of moneys in the Construction Fund or the Rebate Fund shall be retained in such respective fund, investments acquired as an investment of moneys in any fund or account established under this Indenture shall be credited to such fund or account. For the purpose of determining the amount in any fund or account, except the Rebate Fund, the amount of any obligation allocable to such fund or account shall be equal to the purchase price of such obligation (not including accrued interest, if any, paid on the purchase of such obligation) plus the amount of any discount below par accounting for any such discount ratably each year over the term of such obligation (i.e., by dividing the amount of such discount by the number of interest payments remaining to maturity and by multiplying the amount so calculated by the number of interest payment dates having passed since the date of purchase) (in this Section called “amortized value”) provided, however, that the amount of any accrued interest on any obligation shall be credited to the Revenue Fund or to any fund or account to which such amount or any portion thereof may have been transferred from the Revenue Fund; and provided, further, that the amount of any obligation in the Bond Reserve Fund shall be determined as of the fifth day after each Principal Payment Date and shall be the then current market value. The Trustee or the Depositary may sell at the best price obtainable, or present for redemption, any Investment Securities so purchased whenever it shall be necessary in order to provide moneys to meet any required payment, transfer, withdrawal or disbursement from the fund or account to which such Investment
Security is credited, and neither the Trustee nor the Depositary shall be liable or responsible for any loss resulting from such investment.
