Executive Summary

Refinancing gain sharing is a contractual mechanism, specified in some project finance financing documents, that splits the incremental value released by a refinancing, typically additional debt proceeds beyond the amount required to repay the original facility, or the value of a reduced financing cost, between the project sponsors and, in some structures, the original lenders. It reflects the fact that a project's reduced risk profile at refinancing, and therefore its increased refinancing capacity, is attributable at least partly to the original lenders' financing of the higher-risk construction and early operating phases.

Key Takeaways

  • Refinancing gain sharing splits the incremental value released by a refinancing between sponsors and, in some structures, the original lenders.
  • The mechanism reflects that a project's increased refinancing capacity is attributable at least partly to the original lenders having financed the higher-risk construction and early operating phases.
  • Sharing percentages and any threshold conditions are transaction-specific and set out in the original financing documents, not a market-standard default.
  • Refinancing gain is typically calculated as new debt proceeds less the amount required to repay the original facility and refinancing transaction costs.
  • A refinancing model that omits a required gain sharing calculation misstates the sponsor's actual retained value from the refinancing.

Definition

Refinancing gain sharing is a contractual mechanism, specified in some project finance financing documents, that splits the incremental value released by a refinancing between the project sponsors and, in some structures, the original lenders.

Why It Matters

A project's increased refinancing capacity, the higher debt quantum achievable at the same coverage ratios once construction risk has passed, is attributable at least partly to the original lenders having financed the project through its higher-risk construction and early operating phases. Gain sharing provisions reflect this by allocating a portion of the refinancing's incremental value back to those lenders, rather than allowing sponsors to capture the full benefit unilaterally.

Technical Background

Calculating Refinancing Gain

Refinancing Gain = New Debt Proceeds − Original Facility Repayment Amount − Refinancing Transaction Costs
Sponsor Share = Refinancing Gain × Sponsor Sharing Percentage (per financing documents)
Lender Share = Refinancing Gain × Lender Sharing Percentage (per financing documents)

Transaction-Specific Terms

The presence of a gain sharing provision, the specific sharing percentages, and any threshold conditions (for example, a sharing mechanism that applies only above a defined minimum gain) are set out in the original financing documents and vary materially by transaction. There is no market-standard default; a refinancing model must implement whatever the applicable documents specify.

Common Errors

Error Description Risk
Gain sharing omitted A required gain sharing calculation not represented in the model at all Overstates the sponsor's actual retained value from the refinancing
Generic sharing percentage assumed A market-standard or estimated sharing percentage used rather than the transaction's actual documented terms Misstates the sponsor and lender shares relative to the contractual entitlement

Best Practices

Model refinancing gain sharing as an explicit calculation, cross-referenced to the specific clause of the original financing documents that establishes the sharing percentages and any threshold conditions, presented alongside the total refinancing gain so a reviewer can see both the gross value released and its contractual allocation.

Frequently Asked Questions

What is refinancing gain sharing?

A contractual mechanism that splits the incremental value released by a project finance refinancing, typically additional debt proceeds or reduced financing cost, between sponsors and, in some structures, the original lenders.

Why would original lenders be entitled to share in refinancing gain?

Because a project's reduced risk profile at refinancing, and therefore its increased refinancing capacity, is attributable at least partly to the original lenders having financed the higher-risk construction and early operating phases of the project.

How is refinancing gain typically calculated?

As new debt proceeds less the amount required to repay the original facility and less refinancing transaction costs, with the resulting gain split according to the sharing percentages set out in the original financing documents.

Is refinancing gain sharing a standard market term?

No. Its presence, and the specific sharing percentages and any threshold conditions, are transaction-specific and must be modelled exactly as set out in the applicable financing documents, not assumed as a market default.

What happens if a refinancing model omits a required gain sharing calculation?

The model misstates the sponsor's actual retained value from the refinancing, since a portion of the apparent gain is contractually owed to the original lenders rather than available to sponsors in full.

Refinancing Model

A refinancing model is a financial model built to analyse the economics of replacing existing debt with new debt under revised terms. In a project finance or infrastructure context, a refinancing replaces the original construction-phase or early-operational-phase debt with new debt that reflects the reduced risk profile of an operating asset — typically at a lower margin, a longer tenor, or a higher principal amount, or some combination of these. A refinancing model runs the project's financial projections under the proposed new debt terms, calculates the revised DSCR, LLCR, and equity returns, and compares these against the original financing to quantify the benefit of the refinancing.

Refinancing Model Construction

A project finance refinancing model tests replacing an existing debt facility with new terms, typically once a project has de-risked following construction completion or a stable operating track record, and warrants its own construction discipline distinct from the original financial close model. This guide sets out how to build the refinancing switch as a single controlled toggle, how refinancing gain sharing mechanics between sponsors and lenders are typically structured, and the difference between a par and a discounted refinancing.

Gearing Ratio

The gearing ratio, also called the debt-to-equity ratio or leverage ratio depending on how it is expressed, is the proportion of a project finance transaction's total funding provided by debt rather than equity. It is read directly off the sources and uses statement as total debt sources divided by total sources (debt-to-total gearing) or total debt divided by total equity (debt-to-equity gearing), and is one of the central negotiated parameters of a project finance transaction, since it directly determines how much of the project's risk is borne by lenders versus sponsors.
