Section 316(b) of the Trust Indenture Act (the "TIA") states the right of a bondholder to receive payments pursuant to an indenture security cannot be "impaired or affected without the consent of such holder." Historically, issuers and bondholders have not engaged in extensive litigation based on the argument that Section 316(b) provides a broad restriction protecting bondholders' substantive right to actually receive such payments.

Parent company guarantees and performance bonds are typically used in the construction and engineering industries to provide a developer with some security in the event that the contractor breaches the building or engineering contract or, in some circumstances, upon the contractor's insolvency.

In the current economic climate, contractor default is, unfortunately, even more prevalent in the construction and engineering industries, and so the issues surrounding parent company guarantees and performance bonds are very much in focus for developers.
