What financial close means

Financial close is the point at which all finance documents are signed and all conditions precedent (CPs) to the first drawdown are satisfied or waived, so funds can flow. It follows months (often years) of development, bidding, negotiation and due diligence.

The due diligence workstreams

WorkstreamTypical adviserKey questions
TechnicalLenders' technical adviser / independent engineerIs the design sound? Are capex, schedule, opex and performance assumptions reasonable? Is the EPC contractor capable?
LegalLenders' and sponsors' counselAre contracts enforceable and consistent? Is security effective? Are permits in place?
Market / revenueMarket or traffic adviserAre demand and price forecasts credible (for merchant or user-pays risk)?
InsuranceInsurance adviserAre construction and operating insurances adequate and assignable to lenders?
Financial modelModel auditorDoes the model calculate correctly and reflect the contracts?
Tax and accountingTax adviserIs the tax treatment correct and robust?
Environmental and socialE&S consultantDoes the project meet applicable standards (e.g., IFC Performance Standards, Equator Principles)?
KYC / complianceLendersAre sponsors and counterparties acceptable under sanctions and anti-money-laundering rules?

Due diligence reports feed a lenders' base case and the credit approval of each lender.

The path to close: step by step

  1. Term sheet agreed with lenders (pricing, tenor, sizing criteria, key covenants).
  2. Due diligence conducted; findings resolved or mitigated.
  3. Credit approval by each lender.
  4. Documentation negotiated: facility agreement, intercreditor agreement, security documents, accounts agreement, direct agreements, hedging agreements.
  5. Model audit completed and base case agreed.
  6. CP checklist satisfied: signed project contracts, permits, legal opinions, insurance certificates, corporate approvals, equity commitments, hedging executed, fees paid.
  7. Signing and close; first drawdown follows per the funding mechanism.

Interest rate hedging at close

Hedges are usually executed at or just before financial close to lock in rates on the lenders' base case. Rates can move between bid and close, so bids may include rate adjustment mechanisms. Final pricing of the tariff or unitary charge is sometimes adjusted at close to reflect actual swap rates, depending on the contract.

Worked example: a delayed close

Illustrative. A fictional solar IPP in KSA reached agreed documentation, but one land-lease registration was delayed. Lenders would not waive the CP because land rights were core security. The sponsor extended the bid bond, negotiated an extension of the scheduled commercial operation date with the offtaker, and kept the EPC contractor on standby under a limited notice to proceed funded by equity. Close occurred six weeks later. The lesson: CPs that depend on government processes need early tracking and contingency.

Before close: development risk

Until close, sponsors fund development costs at risk. If the project fails to close, those costs may be lost. This is why development capital commands high returns and why sponsors stage spending.

Common mistakes

  • Starting critical permits and land processes too late.
  • Inconsistencies between project contracts discovered during legal due diligence.
  • Model not updated for final negotiated terms before the audit.
  • Underestimating adviser costs and time in development budgets.
  • Poor CP tracking, causing last-minute delays.

Quick self-check

Six months before target close, list every CP and ask: who owns it, what evidence is required, what does it depend on, and what is the realistic date? Highlight any CP that depends on a government body, a third-party consent or another CP. These dependencies are where closes slip, and early escalation is usually far cheaper than extending bid bonds and contractor standby arrangements.

Prompt template: first-pass CP extraction (approved AI tool, approved data room only)

From the facility agreement schedule of conditions precedent (pasted below), list every CP as a table:
CP number as written | condition (verbatim) | likely owner (sponsor, SPV, counsel, lenders, third party) | evidence document
| dependency on another CP or authority. Quote clause numbers. Mark anything ambiguous "CONFIRM WITH COUNSEL".

Counsel verifies the extracted list against the signed schedule before it becomes the tracker of record.

How to measure success

  • Every CP has an owner, evidence requirement, dependency and realistic date six months before target close.
  • No CP marked done without an evidence link.
  • Close achieved on or near the target date, with no waived CPs that lenders consider core security.

Key takeaways

  • Financial close = finance documents signed and conditions precedent satisfied, allowing drawdown.
  • Due diligence spans technical, legal, market, insurance, model, tax, E&S and compliance workstreams.
  • Track CPs with owners, status and evidence; government-dependent CPs need early action.
  • Hedging is typically executed at close; development costs are at risk until close.

Check your understanding

Quick questions to lock in the lesson. They don’t count towards your certificate.

  1. What must happen for financial close to occur?
  2. Which adviser typically reviews whether capex, schedule and performance assumptions are reasonable?
  3. Why are development costs considered 'at risk'?
