Iowa Admin. Code r. 265-30.7
An allocation of an allotment pursuant to this chapter shall remain valid for 150 days from the date of allocation. If the sale of bonds for which an allocation was made has not closed within such time, the allocation shall expire and the allotment shall revert to the governor's designee to be reallocated, if possible; provided, however, that if the 150th day following the date of allocation is a Saturday, Sunday, or any day on which the offices of the state banking institutions or savings and loan associations in the state are authorized or required to close, the expiration date shall be extended to the first day thereafter which is not a Saturday, Sunday or previously described day. All MDA bonds must be issued prior to January 1, 2013.
