(1) Unless terminated earlier by the issuer, an allocation is valid for 120 days from the date the department mails the notice of approval. Prior to the expiration of the 120-day period, the department may extend the period of validity for an additional 30 days on presentation of evidence that an agreement to purchase the cap bonds for which the allocation was given has been obtained from an entity legally authorized to purchase them.
(2) If the cap bonds are not issued within the period of validity as determined under subsection (1), the allocation automatically expires.
(3) All allocations expire on December 31 of the year in which they were made. However, this subsection does not limit the term of an allocation for which a valid carryforward election has been made.
