The Cabinet Committee on Economic Affairs (CCEA) approved the 4-laning of the Muzaffarpur–Sitamarhi–Sonbarsa section of National Highway 22 in Bihar under the Hybrid Annuity Model (HAM). 

 

What is the Hybrid Annuity Model (HAM)?

Origin: Introduced in 2016 by the Ministry of Road Transport and Highways (MoRTH), HAM originated from the Vijay Kelkar Committee Recommendations on Revisiting & Revitalizing the Public-Private Partnerships (PPPs) Model of Infrastructure.

 

Hybrid Conceptualization: HAM blends the upfront cash support of the Engineering, Procurement, and Construction (EPC) model with the long-term annuity payout structure of the Build-Operate-Transfer (BOT-Annuity) model.



Core Financial Mechanics of HAM 

40% Government Construction Grant: NHAI provides 40% of the project cost in five equal cash installments (20% each) based on verified physical completion milestones, reducing developer debt.

 

60% Private Investment: The concessionaire arranges the remaining 60% through private equity and commercial loans from infrastructure lenders.

 

Toll Collection & Traffic Risk Immunity: The private concessionaire does not collect tolls. NHAI collects tolls directly, shielding the private developer entirely from commercial traffic revenue risks.

 

Guaranteed Annuity Stream (15-Year Concession): NHAI repays the private developer's 60% investment through 30 semi-annual annuity installments over 15 years, comprising:

  • Amortized Capital Repayment: Gradual recovery of invested capital.

  • Interest Payments: Calculated on reducing balance (linked to the RBI Repo Rate plus a spread).

  • Inflation-Indexed O&M Payouts: Maintenance payments adjusted against the Consumer Price Index (CPI) and Wholesale Price Index (WPI).

EPC vs BOT-Toll Models vs HAM 

Phase

Contract Regime

Key Characteristics

Phase 1: 2000-2013

BOT-Toll Boom

100% Private financing; Developer bore traffic, land & toll risk. Resulted in collapse due to aggressive bidding and banking NPAs.

Phase 2: 2014-2016

EPC Shift

100% Government funded; NHAI bore all financial burden. Limited by excessive fiscal strain.

Phase 3: 2016-Present

HAM Equilibrium

Optimal risk-sharing: 40% Govt grant + 60% private debt/equity. Success in reviving bank lending and accelerated builds.

 

Conclusion

The Hybrid Annuity Model (HAM) provides an optimal, risk-calibrated PPP framework that protects public finances while mobilizing private engineering excellence to build India's world-class highway network.

PRACTICE QUESTION

Q. With reference to the fund allocation in the Hybrid Annuity Model (HAM), consider the following statements:

  1. The government contributes 40% of the total project cost during the construction period.

  2. This 40% government contribution is disbursed as a lump sum amount at the very beginning of the project signing.

  3. The remaining 60% of the project cost is arranged by the private developer through a mix of debt and equity. 

Which of the statements given above are correct?

A) 1 and 2 only

B) 1 and 3 only

C) 2 and 3 only

D) 1, 2 and 3  

Answer: B  

Explanation:

Statement 1 is correct: The government (such as NHAI) funds 40% of the project cost during the construction phase.

Statement 2 is incorrect: This 40% contribution is not paid as a lump sum at signing; rather, it is disbursed in tranches or installments linked to specific construction milestones.  

Statement 3 is correct: The remaining 60% of the cost is raised by the private developer using a combination of equity and commercial debt.
