Explanation

Correct Answer: C - both greenfield assets and brownfield assets

Key Concepts:

• Greenfield assets refer to new investments or projects that are built from scratch on undeveloped land. These typically have higher risk due to:

  • Construction risk
  • Regulatory approval uncertainties
  • Market entry risks
  • Higher initial capital requirements
  • Longer time to cash flow generation

• Brownfield assets refer to existing, operational assets that are being acquired or expanded. These typically have lower risk due to:

  • Established operations
  • Proven cash flows
  • Existing regulatory approvals
  • Known market position
  • Shorter time to cash flow realization

Portfolio Diversification Principle: When combining greenfield and brownfield assets in a portfolio:

1. Risk reduction through diversification - The different risk profiles of the two asset types help reduce overall portfolio risk
2. Correlation benefits - Greenfield and brownfield assets may have different risk-return characteristics and may not be perfectly correlated
3. Cash flow timing diversification - Brownfield assets provide immediate cash flows while greenfield assets offer future growth potential

Why other options are incorrect:

• Option A (greenfield assets only): Highest risk profile due to all assets being in the development/construction phase with uncertain outcomes
• Option B (brownfield assets only): Lower risk than greenfield-only but higher than a diversified portfolio; lacks the diversification benefits of combining both asset types

Conclusion: A portfolio containing both greenfield and brownfield assets benefits from diversification, which typically results in the lowest overall risk profile when all else is equal.
