Conn. Gen. Stat. § 8-252a

(b) In the event that the total of principal and interest payments and other revenues pledged to any trustee in accordance with a pledge made pursuant to subsection (a) of this section and received in any fiscal year are less than the total of all interest and principal payments and other revenues on loans under any bond-financed housing program as defined in section 8-37qq by the state in that same fiscal year, the Secretary of the Office of Policy and Management shall apportion any payments to be transferred to such trustee under such pledge among payments that would otherwise have flowed to the General Fund, the Rental Housing Fund or the Housing Repayment and Revolving Loan Fund and may, on behalf of the state, make such agreements, covenants and representations with respect to such apportionment as may be required for issuance of the bonds under this section. In the event that principal and interest payments or other revenues pledged pursuant to subsection (a) of this section are transferred in any fiscal year to any trustee in excess of total debt service payments required in such fiscal year under the terms of any indenture of trust for bonds issued under this section the balance shall be returned to the state. Such returned balance shall be apportioned among the General Fund, the Rental Housing Fund or the Housing Repayment and Revolving Loan Fund, as determined by the Secretary of the Office of Policy and Management provided, any such returned balance shall first be apportioned to the Housing Repayment and Revolving Loan Fund, up to the amount which would otherwise have flowed to the Housing Repayment and Revolving Loan Fund in such fiscal year absent such pledge under this section.

(c) Nothing in this section shall be construed to authorize (1) the use of moneys in any sinking fund which may have been pledged by resolution or trust indenture in connection with the issuance of any general obligation bonds, as to which sinking fund the state did not reserve the right to application and use of such moneys for other purposes, (2) the pledge of moneys, any apportionment of payments or returned balances in subsection (b) of this section that the State Treasurer determines to have been precluded by any covenant or agreement with bondholders on any outstanding general obligation bonds of the state, or (3) the pledge of certain loan payments or revenue if it is determined by the State Treasurer that the tax-exempt status of any outstanding general obligation bonds of the state shall be jeopardized by the pledge of such payments or revenues.
