Example:
A borrower sells a $15 million par bond issue to fund a project. The proceeds are given to the trustee who in turn deposits the money in several accounts such as the construction account, the capitalized interest account, and the debt service reserve account and pays off the general expenses of the bond issuance.
The trustee is given the proceeds from a bond issuance and based on the instructions of the borrower, invests, reinvests and expends the money as specified in the bond documents or requested by the issuer.
