Infrastructure debt fund schemes
Also written IDF scheme · Infrastructure Debt Fund scheme · Infrastructure debt fund
A mutual fund scheme that must put at least 90% of its assets into the debt of infrastructure companies, projects and SPVs, with a 30% cap on any single infrastructure borrower.
In plain language
Roads, ports and power plants need money that stays put for fifteen years. Banks lend it, but a bank funds long assets with short deposits, and there is a limit to how much of that mismatch any system can carry.
An infrastructure debt fund scheme is a mutual fund scheme designed to take some of that paper off the banks and hold it for investors instead. The regulation does not merely permit infrastructure lending — it requires it, and then spends most of its length making sure the scheme does not become a dumping ground for the sponsor's own exposures.
How it works
The 90% floor. An infrastructure debt fund scheme means a mutual fund scheme that invests primarily — a minimum of 90% of scheme assets — in the debt securities or securitised debt instruments of:
- infrastructure companies;
- infrastructure capital companies;
- infrastructure projects;
- special purpose vehicles created to facilitate or promote investment in infrastructure;
- other permissible assets under the regulations; or
- bank loans in respect of completed and revenue generating projects of infrastructure companies, projects or SPVs.
The balance. The remaining assets may go into equity shares and convertibles, including mezzanine financing instruments, of companies engaged in infrastructure or infrastructure development projects — listed or not — or into money market instruments and bank deposits.
The concentration cap. Investment in the debt instruments or assets of any single infrastructure company, project or SPV must not exceed 30% of net assets.
The related-party wall. The scheme may not invest at all in any unlisted security of the sponsor, its associate or group company, or in any listed security issued to them by preferential allotment. Listed securities of the sponsor group, or bank loans of the sponsor group's completed and revenue generating projects, are capped at 25% of net assets, and even then only with trustee approval and full disclosure to investors.
Assets or securities owned by the sponsor, the AMC or their associates are capped at 30% of net assets, and all three of the following must hold: the investment is not below investment grade; the sponsor or its associates retain at least 30% of those assets or securities for as long as the scheme holds them; and the trustees approve with full disclosure to investors.
A worked example
Deccan Infrastructure Debt Fund Scheme has net assets of Rs 2,000 crore.
| Holding | Amount | Test |
|---|---|---|
| NCDs of operating toll road SPVs | Rs 1,540 cr | counts toward the 90% floor |
| Bank loans of a completed 400 MW solar project | Rs 300 cr | counts — project is completed and revenue generating |
| Equity of a listed EPC contractor | Rs 90 cr | part of the ≤10% balance |
| Treasury bills and bank deposits | Rs 70 cr | part of the ≤10% balance |
Debt and securitised debt total Rs 1,840 crore = 92% of net assets. The floor is met with 2 percentage points to spare.
Now the fund manager proposes adding Rs 180 crore of NCDs of Konkan Expressway SPV, of which the scheme already holds Rs 460 crore. New exposure would be Rs 640 crore = 32% of net assets — over the 30% single-borrower cap by Rs 40 crore. The trade must be cut to Rs 140 crore or dropped.
Separately, the sponsor offers the scheme Rs 560 crore of listed bonds of a group infrastructure company. That is 28% of net assets, above the 25% ceiling on listed sponsor-group securities. Trustee approval cannot cure it: the 25% is a hard limit, and trustee approval plus disclosure is a condition inside the limit, not a way past it. The most the scheme can take is Rs 500 crore — and only with the trustees' approval on record and full disclosure to investors.
Why NISM asks about it
Chapter 14, section 14.5.2 (Infrastructure Debt Fund Schemes), sitting immediately after real estate mutual fund schemes — the two specialised scheme types are usually examined as a pair, precisely because their percentages differ.
Expect a direct recall question on the 90% minimum and the 30% single-issuer cap, and a harder one on the sponsor-related limits: 25% for listed sponsor-group securities and bank loans, 30% for assets or securities owned by the sponsor, AMC or associates, with the investment-grade, 30%-retention and trustee-approval conditions attached.
Common exam traps
- 90% is the floor for the scheme, 30% is the ceiling for one borrower. Both are percentages of net assets and both get swapped in questions.
- Bank loans qualify only for completed and revenue generating projects. A loan to a project still under construction does not count toward the 90%.
- 25% and 30% are different sponsor limits. 25% applies to listed securities of the sponsor group and their project bank loans; 30% applies to assets or securities owned by the sponsor, AMC or their associates. Unlisted sponsor securities and preferential allotments to the sponsor group are barred outright — no percentage at all.
- The sponsor must retain at least 30% of any asset the scheme buys from it, for as long as the scheme holds it. Skin in the game is a condition of the deal, not an afterthought.
- "Primarily" is defined here. In ordinary regulatory drafting "primarily" is vague; in this definition it is spelled out as a minimum of 90%, so do not answer "a majority".
- Do not confuse this with a plain debt scheme, which has no infrastructure mandate, or with an Infrastructure Investment Trust, which is a listed trust under a separate set of regulations.
Where this is taught
Free preparation for NISM Series III-CRelated terms
- Asset Management CompanyThe company that runs a mutual fund's schemes day to day — appointed by the sponsor or trustees with SEBI's approval, and paid a fee out of the scheme rather than a share of its profits.
- Mutual fundA trust registered with SEBI that pools money from many investors and invests it in securities on their behalf — not a different product from shares and bonds, but a different way of owning them.
- SponsorThe person or firm that sets up the mutual fund — applies to SEBI for registration, executes the trust deed in favour of the trustees, and puts up the capital of the AMC.
- Obligations of trusteesThe duties SEBI places on a mutual fund's trustees: hold scheme property in trust, review every AMC-associate transaction quarterly, and certify to SEBI half-yearly that nothing improper happened.
- Real estate mutual fund schemesA mutual fund scheme holding actual property: at least 35% of net assets directly in completed, unencumbered Indian real estate, and at least 75% in real estate assets and related securities.
- Specialized Investment FundsA SEBI vehicle sitting between mutual funds and PMS: run by an eligible AMC under the Mutual Funds Regulations, with a minimum of Rs 10 lakh per investor across all of that AMC's SIF strategies.
