Refunding escrow
Refunding escrow means one or more funds established as part of a single transaction or a series of related transactions, containing proceeds of a refunding issue and any other amounts to provide for payment of principal or interest on one or more prior issues. For this purpose, funds are generally not so established solely because of -
(1) The deposit of proceeds of an issue and replacement proceeds of the prior issue in an escrow more than 6 months apart, or
(2) The deposit of proceeds of completely separate issues in an escrow.
