A subsidiary of Bermudian-based Assured Guaranty Ltd is helping to facilitate a major construction project at New York’s John F Kennedy International Airport.

Assured Guaranty Municipal Corp has insured $800 million of senior special facilities revenue bonds, series 2023, issued by the New York Transportation Development Corporation.

The bonds insured by AGM are part of a $2 billion issue of fixed-rate bonds that has been designated as green bonds.

The bonds have been issued to refinance a portion of the costs relating to the new terminal one project at JFK by a consortium comprised of Ferrovial Airports (which will manage the project), JLC Infrastructure, Ullico Infrastructure Fund and Carlyle Group.

The consortium will develop, design, construct, finance, operate and maintain the new international passenger terminal facility to replace the existing terminal one at JFK.

Lorne Potash, managing director, Infrastructure Finance, Americas, said: “Assured Guaranty’s bond insurance on $800 million of bonds helped to optimise the cost for this important oversubscribed $2 billion financing and we are thrilled to have played such a significant role in what has resulted in a remarkable execution by Citi on behalf of New Terminal One for such a high-profile transaction.

“This is precisely the kind of meaningful value-add that AGM is positioned to deliver for large infrastructure projects through its cost savings and capacity.”

Sam Nakhleh, director, Infrastructure Finance, Americas, added: “This project is the largest US P3 transportation project to date and is one of the largest insured bond transactions Assured Guaranty has participated in during the post global financial crisis era. It was great to work with all involved.”

The bonds will be fully amortising after an initial interest-only period, with a final maturity in 2060.

AGM insured $97,995,000 of serial bonds with maturities of 2042, 2043 and 2044; $217,510,000 of a term bond due 2049; and $484,495,000 of a term bond due 2060.

Citigroup served as book-running senior manager on the transaction. Hogan Lovells served as AGM’s legal counsel.
