# Debenture Redemption Reserve (DRR) and Investment Requirements
DRR is a statutory cushion to ensure debentures can be redeemed at maturity. The required DRR varies by issuer category and debenture type (publicly vs privately placed).
## 1. DRR Requirements — Category-wise
| Category | Publicly Placed Debentures | Privately Placed Debentures |
|---|---|---|
| All India Financial Institutions (RBI-regulated) | Exempted | Exempted |
| Banking Companies | Exempted | Exempted |
| Listed Companies (other than AIFIs / Banks) | Exempted | Exempted except: NBFCs not registered with RBI u/s 45IA and Housing Finance Companies not registered with NHB |
| Unlisted Companies (other than AIFIs / Banks) | DRR = 10% of Outstanding Debenture | DRR = 10% of Outstanding Debenture except: NBFCs registered with RBI u/s 45IA AND HFCs registered with NHB (exempted) |
Mental shortcut: Banks & AIFIs are fully exempt. Listed companies are largely exempt. Only unlisted non-bank, non-AIFI companies must create the 10% DRR (with specific NBFC/HFC carve-outs for private placements).
## 2. Investment Requirements (15% Rule)
Applicable to:
- Listed Companies — for publicly placed debentures
- Unlisted Companies — for both publicly and privately placed debentures
### The Rule
An amount equal to 15% of debentures maturing during the financial year ending on 31st March of the next year must be invested or deposited in specified instruments by 30th April of the current FY.
### Permitted Modes of Investment/Deposit
- (a) Deposits with any scheduled bank (free from charge/lien)
- (b) Unencumbered securities of the Central Government or any State Government
- (c) Unencumbered securities mentioned in sub-clauses (a) to (d) and (ee) of Section 20 of Indian Trusts Act, 1882, OR unencumbered bonds issued by any other company notified under sub-clause (f) of Sec 20
## 3. Restrictions on Investment
- The investments cannot be used for securing loans or any other purpose.
- They must be used only for redemption of debentures.
- The investment must not fall below 15% of maturing debentures (top-up obligation if it does).
- For partly convertible debentures, DRR is created only on the non-convertible portion.
## 4. Quick Decision Tree
```
Is issuer an AIFI or Banking Company?
YES → Fully exempt from DRR.
NO → Is issuer Listed?
YES → Generally exempt (except specified NBFC/HFC categories on private placement)
NO (Unlisted) → DRR = 10% of outstanding debentures
(NBFCs reg. with RBI u/s 45IA & HFCs reg. with NHB exempt on private placement)
