Project Completion Restriction

What Does Project Completion Restriction Mean?
A type of clause, seen most often in municipal bond indentures, which requires the issuing party to sell debt securities (often in the form of revenue bonds) to finance the full completion of a particular project.

Investopedia explains Project Completion Restriction
Project cash flow projections are rarely certain, and if construction costs exceed estimates, the debt issuer may reconsider the completion or the final structure of the project. A project completion restriction protects the interests of bondholders, as it forces the issuer to secure the debt financing needed to complete the project, which should produce the revenues needed to meet bond payment obligations.
