1. Meaning and legal concept

A waterfall mechanism is a contractually or statutorily prescribed order in which money received, deposited or realised is required to be applied towards specified payments and obligations.

It establishes a predetermined priority for the utilisation and distribution of funds.

Failure to enforce waterfall discipline strictly occurs when a borrower, lender, escrow bank, security trustee, monitoring agency or other responsible party:

Diverts funds from the designated escrow account.

Makes payments in an order different from the agreed priority.

Releases funds to lower-priority creditors before satisfying higher-priority obligations.

Permits unauthorised withdrawals.

Uses project revenues for purposes not permitted under the financing documents.

Fails to monitor and control the movement of funds.

Allows one lender or beneficiary to receive preferential treatment contrary to the agreed waterfall.

Fails to transfer collections to the appropriate account or apply them towards the prescribed obligations.

The fundamental legal principle is that a waterfall mechanism is not merely an accounting arrangement. It is a contractual and financial discipline designed to protect the agreed priority of payments, preserve cash flows and ensure that funds are utilised for their designated purposes.

2. Understanding the waterfall mechanism

In project financing, infrastructure financing, structured finance, securitisation and escrow-based lending arrangements, the borrower is generally required to deposit specified revenues into a designated escrow or trust and retention account.

The funds are then distributed according to a predetermined hierarchy.

Illustrative waterfall structure

Project Revenue / Collections

Toll collections, project receipts, operating revenue

Designated Escrow Account

All prescribed receipts are deposited

1

Statutory dues and taxes

2

Essential project operating expenses

3

Maintenance and insurance expenses

4

Senior lender debt servicing

5

Junior lender debt servicing

6

Debt service reserve replenishment

7

Subordinated debt / permitted distributions

Residual Surplus

Released only as permitted under the financing documents

Illustrative structure only. The actual order depends on the executed escrow, concession and financing agreements.

Why is waterfall discipline important?

The waterfall mechanism ensures:

Priority payments are made in the agreed order.

Senior lenders receive payments before subordinated lenders where the agreement so provides.

Project operating expenses are funded in accordance with the agreed arrangement.

Debt servicing is protected.

Project revenues are not diverted for unauthorised purposes.

The interests of different lenders and stakeholders remain protected.

A departure from the prescribed sequence may disrupt the entire financing structure.

3. Applicable legal framework in India

The legal consequences of failure to follow waterfall discipline depend on the nature of the financing arrangement and the contractual documents.

A. Indian Contract Act, 1872

Section 37 – Obligation to perform contractual promises

Parties to a contract are required to perform their respective promises unless performance is excused under the Act or another applicable law.

Where the financing documents prescribe a specific order for utilisation and distribution of funds, the parties are ordinarily required to follow that arrangement.

Section 39 – Effect of refusal to perform a promise wholly

Where a party refuses to perform, or disables itself from performing, its promise in its entirety, the promisee may be entitled to terminate the contract, subject to the statutory requirements and the circumstances of the case.

An intentional and material departure from an agreed waterfall may, depending on the contractual terms, constitute a breach of contractual obligations.

Section 73 – Compensation for loss or damage caused by breach of contract

Section 73 provides for compensation for loss or damage naturally arising in the usual course from the breach, or which the parties knew to be likely when entering into the contract.

This provision is particularly relevant where unauthorised diversion of escrow funds results in:

Non-payment of senior debt.

Accumulation of overdue interest.

Invocation of guarantees.

Default under financing agreements.

Loss of expected debt recovery.

Additional financing costs.

The claimant must establish breach, causation and legally recoverable loss.

B. Indian Trusts Act, 1882

Where the escrow arrangement creates a trust or imposes fiduciary obligations, relevant provisions of the Indian Trusts Act may become applicable.

Section 11 – Trustee to execute trust

A trustee is bound to fulfil the purpose of the trust and obey the directions of the author of the trust, except where such directions are modified by law.

Section 15 – Care required from trustee

A trustee must deal with trust property with the care that an ordinarily prudent person would take of similar property belonging to them.

Section 23 – Liability for breach of trust

A trustee who commits a breach of trust is liable to make good the loss suffered by the trust property or beneficiary, subject to the statutory framework.

Legal significance: Where an escrow agent or trustee holds money subject to a defined payment hierarchy, unauthorised diversion or distribution contrary to the governing trust arrangement may give rise to liability for breach of trust.

However, not every escrow arrangement automatically creates a trust. The actual agreement and legal structure must be examined.

C. Companies Act, 2013

Where the arrangement concerns debenture financing, the provisions governing debenture trustees and protection of debenture holders may become relevant.

In particular, Section 71 and the applicable rules concerning debenture trustees should be examined.

D. Insolvency and Bankruptcy Code, 2016 – Section 53

Section 53 provides a statutory waterfall mechanism for distribution of liquidation proceeds.

The prescribed priority broadly includes:

Insolvency resolution process costs and liquidation costs.

Workmen's dues for the prescribed period and debts owed to secured creditors who relinquish their security.

Employee dues.

Unsecured financial creditors.

Certain government dues and unpaid secured-creditor claims following enforcement.

Remaining debts and dues.

Preference shareholders.

Equity shareholders or partners.

Important distinction: Section 53 applies to distribution of liquidation assets under the IBC. It should not be confused with a contractual project-finance waterfall operating through an escrow account during the ordinary course of a project.

E. SARFAESI Act, 2002

Where security is enforced under SARFAESI, the applicable provisions concerning enforcement, realisation and distribution of proceeds must be considered.

Section 13 governs enforcement measures, while Section 13(7) addresses the application of amounts received by the secured creditor towards costs, charges and expenses and the debt, with any surplus dealt with as provided by law.

The contractual waterfall and statutory distribution requirements must be considered together where both apply.

4. Important case laws and judicial precedents

Case 1: Paschimanchal Vidyut Vitran Nigam Ltd. v. Raman Ispat Private Limited

Supreme Court – Important authority

Citation: (2023) 10 SCC 60; 2023 INSC 625.

Court: Supreme Court of India.

Facts:

The case concerned the distribution of assets of a corporate debtor under the Insolvency and Bankruptcy Code.

A dispute arose regarding the priority of claims during liquidation and the statutory hierarchy prescribed under Section 53 of the IBC.

The question was whether the statutory order of priority could be altered to give preference to particular claims.

Supreme Court's findings:

The Supreme Court explained that Section 53 creates a structured statutory hierarchy for distribution of liquidation proceeds.

The Court emphasised that the waterfall mechanism is based on a carefully structured order of priority.

It observed that rearranging the statutory hierarchy may produce cascading consequences for the interests of secured creditors, operational creditors, employees and government authorities.

Legal principle established:

The prescribed waterfall is intended to maintain an orderly and legally recognised hierarchy of payments. Its priorities cannot be arbitrarily rearranged.

Application to the present issue:

This decision is useful where a party distributes funds contrary to a legally prescribed statutory priority.

It supports the proposition that the payment hierarchy is a substantive legal arrangement and not an administrative formality.

Important qualification: This judgment concerns the statutory liquidation waterfall under Section 53 of the IBC, not a private escrow waterfall under a project-financing agreement.

Case 2: Transstroy Tirupati Tiruthani Chennai Expressways Pvt. Ltd. v. Allahabad Bank

Directly relevant to escrow waterfall

Court: Delhi High Court.

Decision: 9 July 2019.

Proceedings: O.M.P. (I) (COMM.) No. 456 of 2018.

Facts:

The matter concerned a highway project and an escrow arrangement governing the deposit and utilisation of project revenues.

The Escrow Agreement required toll collections to be deposited into a designated escrow account.

The agreement also prescribed a specific order of priority for withdrawal and utilisation of funds.

The waterfall included payments towards:

Taxes.

Construction-related expenses.

Operation and maintenance expenses.

Certain payments to NHAI.

Other contractually prescribed project obligations.

The dispute arose concerning the operation of the escrow arrangement and the parties' rights under the prescribed payment hierarchy.

Legal significance:

The Delhi High Court examined the contractual waterfall and the obligations arising from the Escrow Agreement.

The case demonstrates that the parties' rights concerning project revenues must be determined by examining the precise contractual order of appropriation and the escrow arrangements.

Legal principle:

Where an escrow agreement prescribes a particular order for utilisation of project receipts, the contractual arrangement must be examined and enforced according to its terms.

A party cannot simply disregard the agreed sequence and treat the escrow balance as freely available funds.

Application:

This judgment is particularly useful in cases involving:

Highway projects.

Toll collections.

Infrastructure financing.

Escrow accounts.

Unauthorised withdrawals.

Disputes between lenders and project companies.

Case 3: Park Energy Pvt. Ltd. v. Syndicate Bank & Others

Important project-finance precedent

Court: National Company Law Appellate Tribunal.

Decision: 24 August 2020.

Facts:

The dispute involved financing arrangements for a power project.

The lenders and the project company had entered into a Trust and Retention Account Agreement dated 26 July 2018.

Under the arrangement:

Project revenues were required to flow into the designated Trust and Retention Account.

A specified bank was authorised to operate the account.

The agreement provided for a waterfall mechanism governing payment priorities.

The arrangement prescribed the priority of payments to working capital lenders and term lenders.

A dispute arose when Syndicate Bank decided to unilaterally reduce the letters of credit facility being provided to the project company.

The appellant argued that the action adversely affected the project's operations and jeopardised the ability of the lenders to receive repayment through continuing project revenues.

Legal significance:

The case demonstrates the importance of coordinated lender arrangements, the Trust and Retention Account Agreement and the agreed payment waterfall in project financing.

It also highlights that unilateral actions by a lender may have consequences for the functioning of the overall financing structure.

Application:

This authority is useful where a lender or financial institution acts unilaterally in a manner inconsistent with an agreed financing and cash-flow arrangement.

Important qualification: The dispute should not be cited as a general holding that every departure from a waterfall constitutes a violation. The actual contractual clauses and findings must be examined.

Case 4: State Bank of India v. National Highways Authority of India & Others

Important infrastructure-finance decision

Court: National Company Law Appellate Tribunal.

Decision: 19 September 2024.

Facts:

The dispute concerned payments arising from infrastructure concession arrangements involving IL&FS entities.

A controversy arose over the priority of concession fees and other project-related payments vis-à-vis repayment of bank loans.

The parties relied on the relevant Concession Agreement and Escrow Agreement.

The argument was that the contractual waterfall placed certain concession-related payments ahead of debt servicing by lenders.

Legal significance:

The decision illustrates that the priority of payments must be determined from the actual contractual waterfall and cannot be decided merely by looking at the identity of the creditor or the nature of the debt.

Application:

This judgment is relevant where:

A bank claims priority over project revenues.

A concession agreement prescribes a different payment hierarchy.

A project company or escrow bank makes payments outside the agreed sequence.

There is a dispute between lenders and infrastructure authorities concerning project cash flows.

Case 5: Moser Baer Karamchari Union v. Union of India

Supreme Court

Citation: 2023 INSC 479.

Court: Supreme Court of India.

Facts:

The case concerned the constitutional validity and operation of provisions relating to distribution of assets under the Insolvency and Bankruptcy Code, particularly the statutory liquidation priority.

The Court considered the relative treatment of workmen, secured creditors and other stakeholders.

Supreme Court's findings:

The Court explained that the statutory waterfall is a carefully structured hierarchy.

Changing the prescribed order may have cascading effects on the rights and interests of different classes of stakeholders.

Legal principle:

A statutory waterfall is intended to preserve a structured and predictable system of priority.

Application:

This decision may be relied upon when challenging an attempt to disregard or rearrange the statutory order of priority under Section 53 of the IBC.

5. Additional relevant decision: NHAI v. Guruvayoor Infrastructure Pvt. Ltd.

Court: Delhi High Court.

Proceedings: OMP (ENF.) (COMM.) 97/2024.

Facts and significance:

The dispute concerned compliance with payment obligations under an infrastructure concession and escrow arrangement.

The Delhi High Court dealt with directions requiring maintenance of a specified minimum balance in the escrow account and periodic payments towards the negative grant.

The matter illustrates the importance of enforcing contractual and arbitral payment priorities in infrastructure projects.

The decision is useful in understanding that escrow balances and prescribed payments may be subject to judicial enforcement rather than being freely available for other purposes.

6. Comparative analysis of the case laws

7. What constitutes a breach of waterfall discipline?

The following situations may constitute a breach, depending on the contractual provisions.

Example

Suppose a project has generated ₹100 crore in revenue.

The financing documents prescribe the following payment hierarchy:

If the project company pays ₹20 crore to junior lenders before satisfying the senior lender's ₹40 crore entitlement, the transaction may violate the agreed waterfall.

Similarly, if the escrow bank permits the borrower to withdraw ₹30 crore for unrelated purposes without the approvals required under the escrow agreement, it may constitute a serious contractual breach.

The exact legal consequences depend on whether the relevant payments were actually due, whether sufficient funds were available and whether the agreement permitted any exceptions.

8. Legal consequences of failure to enforce waterfall discipline

A. Breach of financing agreement

If the borrower or another responsible party diverts money contrary to the agreed order, it may constitute a breach of the financing agreement, escrow agreement or inter-creditor agreement.

The affected lender may invoke contractual remedies, including events of default, acceleration or enforcement, subject to the terms of the relevant documents.

B. Breach of escrow obligations

An escrow bank or account operator may be liable if it releases funds contrary to valid contractual instructions or exceeds its authority.

Its responsibility must be assessed from the escrow agreement, mandate and applicable legal duties.

C. Breach of trust

Where the escrow arrangement creates a trust, diversion of funds contrary to the trust purposes may constitute a breach of trust.

Sections 11, 15 and 23 of the Indian Trusts Act may become relevant.

D. Financial loss to lenders

Failure to follow the waterfall may result in:

Non-recovery of senior debt.

Accumulation of overdue interest.

Deterioration of debt-servicing capacity.

Reduction in available security.

Invocation of guarantees.

Additional litigation and recovery expenses.

Increased risk of insolvency.

E. Liability for damages

Under Section 73 of the Indian Contract Act, the affected party may claim compensation for losses naturally arising from the breach, provided the loss is legally recoverable and causally connected with the breach.

F. Insolvency consequences

Where the matter involves liquidation under the IBC, any distribution contrary to Section 53 may be challenged under the applicable insolvency framework.

The statutory waterfall cannot be overridden by an arrangement between private parties where such arrangement would unlawfully disturb the statutory order.

9. Responsibility of different stakeholders

An important aspect of waterfall discipline is identifying who was responsible for ensuring compliance.

A party cannot automatically be held liable simply because it participated in the financing arrangement. Its specific contractual and statutory responsibilities must be established.

10. Evidence required to establish violation

For establishing failure to enforce waterfall discipline, the following documents are particularly important:

Facility agreement and sanction letter.

Escrow agreement.

Trust and Retention Account Agreement.

Inter-creditor agreement.

Security trustee agreement.

Bank account statements.

Project revenue collection statements.

Cash-flow statements.

Debt servicing schedules.

Debt Service Reserve Account statements.

Approval letters for withdrawals.

Internal instructions issued to the escrow bank.

Records of payments made to different lenders.

Audit and monitoring reports.

Correspondence relating to unauthorised withdrawals.

Reconciliation of actual payments with the contractual waterfall.

The most important exercise is to prepare a transaction-wise comparison between the prescribed waterfall and the actual movement of funds.

This establishes precisely when, how and by whom the payment hierarchy was violated.

11. Suggested legal grounds for a complaint or written submission

The following grounds can be raised where the facts establish a departure from the agreed waterfall.

Ground I – Violation of contractual payment priority

The responsible party failed to adhere to the order of priority expressly prescribed under the financing and escrow agreements.

Ground II – Unauthorised diversion of project receipts

Project revenues were diverted or utilised for purposes other than those authorised under the contractual cash-flow arrangement.

Ground III – Failure of escrow-account supervision

The escrow bank or other responsible entity failed to exercise its contractual responsibilities in ensuring that disbursements were made strictly in accordance with the prescribed payment hierarchy.

Ground IV – Preferential treatment of lower-priority creditors

Payments were released to junior or subordinated creditors before satisfying the obligations of higher-priority creditors, contrary to the governing agreements.

Ground V – Failure to protect senior lenders' interests

The failure to enforce the agreed payment sequence impaired the repayment structure and prejudiced the rights and interests of the senior lenders.

Ground VI – Failure to maintain debt-service reserves

Amounts required to be maintained in the DSRA were diverted or not replenished, thereby weakening the financial safeguards contemplated under the financing documents.

Ground VII – Financial loss arising from breach

The departure from the prescribed waterfall resulted in non-recovery, additional interest, increased exposure and other demonstrable financial consequences.

12. Suggested legal drafting for a complaint or written submission

Writing

FAILURE TO STRICTLY ENFORCE THE PRESCRIBED WATERFALL MECHANISM

It is respectfully submitted that the concerned parties failed to ensure strict compliance with the prescribed waterfall mechanism governing the collection, appropriation, utilisation and distribution of project revenues and other receivables.

The financing arrangements, including the Facility Agreement, Escrow Agreement and other related financing documents, prescribed a specific order of priority for utilisation and disbursement of funds. Such arrangement was intended to ensure that statutory obligations, essential project expenses, senior debt servicing, subordinate debt obligations and other permitted payments were discharged in the stipulated sequence.

However, the concerned parties failed to enforce the prescribed payment hierarchy and permitted, or failed to prevent, the diversion, unauthorised withdrawal and/or disbursement of funds contrary to the agreed waterfall mechanism.

Such conduct undermined the contractual safeguards created for protecting the cash flows and repayment obligations of the project and adversely affected the rights and interests of the beneficiaries entitled to receive payments in accordance with the prescribed priority.

The aforesaid conduct prima facie constitutes a breach of the applicable contractual obligations and warrants examination under Sections 37, 39 and 73 of the Indian Contract Act, 1872, wherever applicable.

Where the escrow arrangement creates a trust or fiduciary obligation, the provisions of Sections 11, 15 and 23 of the Indian Trusts Act, 1882 may also become relevant.

The legal significance of maintaining the prescribed payment hierarchy has been recognised by the Supreme Court in Paschimanchal Vidyut Vitran Nigam Ltd. v. Raman Ispat Private Limited, (2023) 10 SCC 60, wherein the Court explained the importance of maintaining the statutory waterfall and the consequences of disturbing the prescribed order of priority.

Further, in Moser Baer Karamchari Union v. Union of India, 2023 INSC 479, the Supreme Court recognised that a waterfall mechanism represents a structured hierarchy of competing stakeholder rights and that disturbing such hierarchy may have cascading consequences.

The decision in Transstroy Tirupati Tiruthani Chennai Expressways Pvt. Ltd. v. Allahabad Bank, decided on 9 July 2019, is also relevant in examining the contractual obligations governing the deposit and utilisation of project revenues through a designated escrow account.

Further, Park Energy Pvt. Ltd. v. Syndicate Bank & Others, decided on 24 August 2020, illustrates the significance of the Trust and Retention Account Agreement and the agreed payment priorities in project-financing arrangements.

It is therefore submitted that the failure to enforce the prescribed waterfall mechanism constitutes a serious departure from the agreed financial discipline and requires an examination of the actual flow and utilisation of funds.

The concerned parties should accordingly be directed to produce the escrow-account statements, transaction-wise disbursement records, lender-wise payment details, DSRA statements, internal withdrawal approvals, reconciliation statements and other relevant documents to establish whether each payment was made in accordance with the prescribed priority.

The financial consequences of the deviation, including any diversion of funds, non-payment of higher-priority obligations, accumulation of interest and impairment of debt recovery, should also be quantified.

Appropriate contractual, civil, regulatory or insolvency-related action may thereafter be considered in accordance with the applicable legal framework.

13. Conclusion – Central legal proposition

The central legal proposition is:

A waterfall mechanism creates an agreed or statutory hierarchy governing the application and distribution of funds. Failure to enforce that hierarchy, including unauthorised diversion of receipts or payments to lower-priority beneficiaries before satisfying higher-priority obligations, may constitute a breach of contractual or statutory obligations and may result in liability for the consequential loss.

The most useful judgments for this issue are:

Paschimanchal Vidyut Vitran Nigam Ltd. v. Raman Ispat Private Limited (2023) – Supreme Court; statutory waterfall and preservation of payment priorities.

Transstroy Tirupati Tiruthani Chennai Expressways Pvt. Ltd. v. Allahabad Bank (2019) – Delhi High Court; contractual escrow and project-revenue utilisation.

Park Energy Pvt. Ltd. v. Syndicate Bank (2020) – NCLAT; Trust and Retention Account and project-financing arrangements.

Moser Baer Karamchari Union v. Union of India (2023) – Supreme Court; structured statutory hierarchy and stakeholder priorities.

State Bank of India v. National Highways Authority of India (2024) – NCLAT; priority under infrastructure concession and escrow arrangements.

14. Important distinction for applying these judgments

There are two different types of waterfall mechanisms:

Contractual waterfall: Prescribed under facility agreements, escrow agreements, concession agreements, inter-creditor agreements or trust deeds.

Statutory waterfall: Prescribed by legislation, particularly Section 53 of the Insolvency and Bankruptcy Code, 2016.

The legal basis and remedies are different. Section 53 cannot automatically be applied to an ordinary escrow-account dispute.

For a strong legal pleading, the actual escrow agreement and its payment-priority clause should be the primary foundation, with judicial precedents used to support its interpretation and enforcement.

The above explanation contains no external website links. It is a general legal analysis; the precise holdings and paragraph references should be verified against the certified judgments before filing in court or before a tribunal.
