An issuing authority may submit to the board a request for carryforward election allocation with respect to private activity bonds proposed to be issued to finance bonds for a specified carryforward purpose. The date for submission of such requests shall be established by the board annually. A separate request must be submitted for each carryforward purpose, except that a request for carryforward election allocation with respect to qualified student loan bonds or qualified mortgage bonds may cover all proposed issuances of student loan bonds and qualified mortgage bonds. Not later than December 26 of a calendar year or the next business day if December 26 is a holiday, the board shall issue carryforward election allocations in amounts determined by the board, to the extent that sufficient amounts are available in the state private activity bond fund and the requirements of the Private Activity Bond Act are satisfied. A request for carryforward election allocation shall contain the same information and materials required to be included in a request for allocation.
