Pursuant to St. 1988, c. 211, § 2, all of Massachusetts' annual state ceiling is assigned to the Commonwealth of Massachusetts. The Executive Office for Administration and Finance (A&F) shall at its discretion allocate any of such state ceiling to issuers within the state, including municipalities and issuers of student loan bonds, housing bonds and other private activity bonds requiring allocation. A&F may also reassign any of the annual state ceiling to the Department of Housing and Community Development (DHCD) or to the Massachusetts Development Finance Agency (MDFA) for further allocation or carryforward. Any such reassignment shall be in writing and shall be subject to such conditions as A&F may specify, including the prior approval by A&F of guidelines issued by DHCD and MDFA, and shall specify when and if such reassignment shall expire.
