Introduction
In multinational companies, investment appraisal is complicated by differences in risk across projects and countries. Simply discounting foreign project cash flows at the parent company's group-wide weighted average cost of capital (WACC) fails to account for variations in business activities, financial structure, and country-specific risk. Instead, financial managers must identify when, and how, to use project-specific discount rates, factoring in country risk premiums and multi-currency cash flows.
This article provides a clear approach for ACCA candidates on adjusting the cost of capital for international projects, covering the adjustment for business and country risk, and the practical methods for multi-currency NPV calculations.
PROJECT-SPECIFIC COST OF CAPITAL: RISK ADJUSTMENT
When evaluating an investment, the risk profile of the project may differ significantly from the company’s current business operations and capital structure. In these cases, using the group WACC as the discount rate can misstate the project's true value.
Key Term: project-specific discount rate
A rate of return that reflects the unique business and financial risk of a particular investment project; used when the project’s risk profile differs from the main operations of the company.
To determine the correct project-specific rate, two main types of risk must be considered:
- Business risk: The degree of uncertainty regarding cash flows from project operations.
- Financial risk: The risk created by the financial structure (debt/equity) used to fund the project.
When the business risk or financial structure of a new project differs materially from that of the firm's core activities, a risk-adjusted rate must be calculated. This is achieved using beta estimation.
Key Term: beta
A measure of an asset’s systematic risk relative to the overall market; used to calculate expected returns in the CAPM framework.
Calculating a Project-Specific Beta
- Obtain a proxy equity beta for a company engaged primarily in the same type of business as the project.
- De-gear the equity beta to obtain the asset (unlevered) beta, removing the effect of capital structure.
- Re-gear the asset beta to reflect the target/project capital structure, capturing the financial risk intended for the project.
- Apply the Capital Asset Pricing Model (CAPM) using the project beta, risk-free rate, and relevant market risk premium.
Key Term: asset beta
A company’s beta assuming it is all-equity financed; measures only business risk.Key Term: country risk premium
An extra return added to the risk-free rate or market risk premium to account for additional political, economic, or regulatory risks in a specific country.
Worked Example 1.1
A UK engineering firm, with a current equity beta of 1.1 and gearing of 40% debt to 60% equity, is considering a project in a foreign country's food sector. Quoted food sector companies in the target country have an average equity beta of 1.4 and gearing of 20% debt to 80% equity. The firm's planned capital structure for the project matches its group structure. The risk-free rate is 4%, the market risk premium is 6%, and an additional country risk premium of 2% is considered appropriate.
Calculate the project-specific cost of equity for the appraisal.
Answer:
Step 1: De-gear sector beta (food sector proxy, geared at 20:80):
Asset beta = 1.4 × (0.8 / [0.8 + 0.2 × (1 - 0.3)]) = 1.4 × (0.8 / 0.94) ≈ 1.19
Step 2: Re-gear for project structure (40:60 gearing):
Project equity beta = 1.19 × ([0.6 + 0.4 × (1 - 0.3)] / 0.6) = 1.19 × (0.88 / 0.6) ≈ 1.75
Step 3: Apply CAPM including the country risk premium:
Cost of equity = 4% + 2% + 1.75 × 6% = 4% + 2% + 10.5% = 16.5%
Exam Warning
Be careful to use market values—not book values—of debt and equity when calculating gearing for beta adjustment. Using the wrong figures can materially distort your result.
COUNTRY RISK PREMIUMS IN OVERSEAS PROJECTS
Standard discount rates based on developed market risk may understate the true required return for high-risk countries. These countries might have unstable political environments, undeveloped capital markets, or volatile economies, all of which demand extra compensation for risk.
A country risk premium is used to bridge this gap. It is typically estimated by:
- Taking sovereign bond yield spreads versus a developed market’s government bonds
- Analysing country credit ratings and adding an estimated spread to the market risk premium
The country risk premium is then:
- Added to the risk-free rate
- Or added directly to the required return calculated via CAPM
Projects exposed to significant country risk require this adjustment to avoid overestimating project value.
Worked Example 1.2
A multinational is considering building a plant in a country whose government bonds yield 6% above US Treasuries. The local sector asset beta is 1.2. The market risk premium is 5%. Calculate the minimum appropriate discount rate for the project, ignoring tax/gross adjustments for simplicity.
Answer:
Minimum discount rate = risk-free rate + country risk premium + (asset beta × market risk premium).
Assuming a US risk-free rate of 3%, discount rate = 3% + 6% + (1.2 × 5%) = 3% + 6% + 6% = 15%.
MULTI-CURRENCY PROJECT APPRAISAL
International projects usually generate cash flows in different currencies. Standard practice is to:
- Forecast future cash flows in each currency
- Forecast relevant exchange rates (often using purchasing power parity or forward curves)
- Translate future foreign currency cash flows into the home currency at forecast exchange rates
- Discount all cash flows using the home currency risk-adjusted rate (including all relevant risk premiums)
Key Term: purchasing power parity
An economic theory stating that exchange rates adjust over time so that identical goods cost the same in different countries, allowing for inflation differentials.
Worked Example 1.3
A UK parent expects project inflows of €1m in year 1 and €1.05m in year 2. UK inflation is 3%, Eurozone inflation is 1%, and today’s spot rate is €1.20/£1. Using purchasing power parity, estimate year-1 and year-2 exchange rates and the GBP value of the inflows.
Answer:
Year 1 rate: €1.20 × (1.01/1.03) = €1.177/£1
Year 2 rate: €1.177 × (1.01/1.03) = €1.155/£1
Year 1 inflow in GBP: €1m / 1.177 ≈ £849,000
Year 2 inflow in GBP: €1.05m / 1.155 ≈ £909,000
Summary
Project appraisal in an international context requires careful adjustment of the discount rate for business risk, financial structure, and the specific country risk premium. When multi-currency cash flows are involved, reliable forecasts of exchange rates and consistent currency conversion in the NPV calculation are essential. Using group WACC without specific risk adjustment can lead to flawed investment decisions. Correct identification and quantification of risk ensure more accurate project valuations.
