Completion guarantee
A completion guarantee is a form of sponsor support under which shareholders undertake to back project completion, and often related funding or debt-service shortfalls, until defined completion tests are met. IFC describes limited-recourse project finance as frequently including a precompletion guarantee during the construction period or other assurances of support, while creditors still look to project success as the primary repayment source. In IFC's construction-risk mitigants, sponsor support until physical and financial completion is certified sits alongside turnkey contracting and contingency as standard protection against cost overruns and delay.
Completion guarantee use on bank project finance desks
On project finance desks a completion guarantee is the core reason many greenfield loans are limited recourse rather than pure non-recourse. After financial close, lenders face construction, commissioning and budget risk before the commercial operation date (COD). The sponsor guarantee bridges that gap by covering completion funding, cost overruns, or debt service until physical and financial completion tests release the support. The former standalone project-finance annex that once addressed post-completion sponsor recourse under the OECD Arrangement is gone from the current Arrangement text; IFC's limited-recourse framing, rather than a dedicated annex, is what documents the norm of reduced or no sponsor recourse once completion tests are met.
The guarantee is complementary to, not a substitute for, the EPC contract. The Phu My 2-2 appraisal describes a fixed-price, date-certain turnkey contract with a completion schedule consistent with contractual COD and plant-performance guarantees. Sponsor completion support stands behind residual gaps if the EPC contractor's liability caps, delay damages or solvency prove insufficient.
Typical scope and release tests
Completion support packages commonly include:
- guarantees of timely physical completion to agreed specification
- undertakings to fund cost overruns or provide contingent equity
- debt-service or shortfall support until completion
- share retention and control undertakings through the construction period
Release usually requires certificates of physical completion, satisfaction of performance tests, and financial completion tests such as funding of reserves, absence of defaults and achievement of projected coverage ratios. The PPP glossary distinguishes completion risks as risks relating to construction completion and the facility's initial ability to provide required services, and treats a completion bond as security from the construction subcontractor for performance under the construction subcontract. Sponsor completion guarantees sit at ownership level; contractor bonds sit at procurement level.
Distinctions from contractor security and offtake support
A completion guarantee is sponsor recourse during construction. A performance bond or retention bond is third-party security for contractor performance. An offtake agreement supports operating revenues after COD and does not complete the plant. Once release conditions are met, the financing is intended to rest on project cash flow and security, consistent with IFC's limited-recourse framing.
