Money in any such trust fund may be invested in direct obligations of or obligations the principal of and interest on which are guaranteed by the United States Government, in obligations of any agency or instrumentality of the United States Government, or in certificates of deposit issued by a bank or trust company if such certificates are secured by a pledge of any of such obligations having an aggregate market value, exclusive of accrued interest, equal at least to the principal amount of the certificates so secured. Nothing in this section shall be construed as a limitation on the duration of any deposit in trust for the retirement of obligations being refunded but which shall not have matured and which are not presently redeemable or, if presently redeemable, have not been called for redemption.
