NISM-Series-XIX-E: Category III Alternative Investment Fund Managers — Chapter 12: Valuation (Part 3 of 5)
1. Discounted Cash Flow (DCF) Valuation: Core Philosophy
1.1 The Theoretical Foundation of DCF in Alternative Investments
The Discounted Cash Flow (DCF) methodology is widely regarded as the most theoretically robust approach to business valuation. Unlike asset-based approaches that focus on historical costs, DCF determines the current value of an enterprise by projecting its future economic benefits and discounting them back to the present day using a risk-adjusted discount rate.
In Category III Alternative Investment Funds (AIFs), particularly when evaluating unlisted investee companies with high growth potential, DCF is crucial. Because these companies focus on internal growth and rarely distribute profits via dividends, traditional dividend-discount models fail. Alternative investment managers instead utilize DCF to value the entire business entity (Enterprise Value), from which the individual share value is subsequently derived.
1.2 The General Valuation Workflow
The DCF valuation process follows a standardized corporate finance workflow:
| Step | Valuation Stage | What It Involves |
|---|---|---|
| 1 | Project Free Cash Flows | Forecast the company's Free Cash Flows (FCF) over a 5-year horizon |
| 2 | Estimate Terminal Value | Calculate the Terminal Value using the perpetuity approach |
| 3 | Determine Cost of Capital | Calculate the Weighted Average Cost of Capital (WACC) |
| 4 | Calculate Enterprise Value | Discount projected FCFs and terminal value to present value to determine Enterprise Value (EV) |
| 5 | Derive Equity Value | Deduct outstanding debt from Enterprise Value to arrive at Equity Value |
| 6 | Calculate Value Per Share | Divide Equity Value by the number of shares outstanding to determine the estimated value per share |
2. Step 1: Free Cash Flow (FCF) Computation
2.1 Operating Cash Flow (OCF) vs. Free Cash Flow (FCF)
To perform a DCF valuation, an investment analyst must project the target company's cash-generating capacity over an explicit forecast horizon (typically 5 years). This begins by estimating the future Operating Cash Flow (OCF) from projected financial statements.
The OCF Projection Formula:
OCF = Profit After Tax (PAT) + Depreciation +/- Non-cash charges in the P&L Account +/- Changes in working capital
- Non-Cash Adjustments: Non-cash items such as Depreciation and Amortisations are added back to Profit After Tax (PAT) because they do not involve an actual outflow of cash.
- Working Capital Adjustments: Changes in Net Working Capital represent cash tied up or released. An increase in working capital acts as a cash outflow (subtracted), while a decrease acts as a cash inflow (added).
Transitioning to Free Cash Flow:
Operating Cash Flow does not represent the net cash available to investors. A business must continuously reinvest in itself to maintain and grow its operations. These are known as reinvestment requirements:
- Capital Commitments (Capital Expenditure / Capex): Ongoing physical capital investments required to maintain or expand fixed assets.
- Debt Repayments: Principal repayments on long-term accounts.
To find the true Free Cash Flow (FCF), these reinvestment requirements and debt repayments are subtracted from OCF:
Free Cash Flow = Operating Cash Flow - Reinvestment Requirements in Fixed Assets - Debt Repayments
2.2 Case Study: Demonstration Investee Company Limited
The NISM-Series-XIX-E curriculum details the projected Free Cash Flow computation of a Demonstration Investee Company Limited from Year 0 (Y0) to Year 5 (Y5).
Below is the structured, step-by-step cash flow model (all values in INR Lakh):
| Line Item | Y0 | Y1 | Y2 | Y3 | Y4 | Y5 |
|---|---|---|---|---|---|---|
| Profit After Tax (PAT) | 1,078.00 | 1,369.29 | 1,599.40 | 1,857.51 | 2,173.29 | 2,542.74 |
| Depreciation (+) | 8.40 | 10.23 | 11.25 | 12.38 | 13.87 | 15.53 |
| Other Amortisations (10% of PAT) (+) | 107.80 | 136.93 | 159.94 | 185.75 | 217.33 | 254.27 |
| Gross Free Cash Flow | 1,194.20 | 1,516.45 | 1,770.58 | 2,055.64 | 2,404.48 | 2,812.55 |
| Changes in Working Capital (10% of PAT) (-) | - | 136.93 | 159.94 | 185.75 | 217.33 | 254.27 |
| Capital Commitments (Capex) (-) | - | 2.19 | 2.41 | 2.65 | 2.92 | 3.21 |
| Free Operating Cash Flow | 1,194.20 | 1,377.33 | 1,608.24 | 1,867.24 | 2,184.24 | 2,555.06 |
| Non-Operating Income (2% of PAT) (+) | - | 27.55 | 32.16 | 37.34 | 43.68 | 51.10 |
| Total Free Cash Flow | 1,194.20 | 1,404.87 | 1,640.40 | 1,904.58 | 2,227.92 | 2,606.17 |
Key Underlying Assumptions of the Model:
- Amortisation Rate: Other amortisations are assumed to be 10% of PAT and are added back.
- Working Capital Reinvestment: Changes in net working capital represent a cash outflow of 10% of PAT each year.
- Capital Expenditures: Ongoing capex is subtracted as a capital commitment.
- Non-Operating Income: Expected non-operating income of 2% of PAT is added back to arrive at the Total Free Cash Flow.
3. Step 2: The Terminal Value (TV)
3.1 Understanding the Role of Terminal Value
A business is fundamentally valued as a going concern, meaning its operations are assumed to continue indefinitely beyond the explicit forecast period (Year 5). The Terminal Value captures the present value of all expected cash flows generated by the business in perpetuity beyond the explicit projection horizon.
Because it represents the long-term future of the enterprise, the Terminal Value often accounts for a disproportionately large share of the total Enterprise Value, making its assumptions highly sensitive.
3.2 Setting the Terminal Growth Rate (g)
The perpetual growth rate (g) applied to the cash flows must be chosen with extreme care. The NISM workbook defines the following industry benchmarks:
- Consolidated and Mature Industries: The terminal growth rate is normally expected to be 2% to 3% above the prevailing long-term inflation rate.
- Example: If the long-term inflation rate is 3%, a standard terminal growth rate would sit around 5% to 6%.
- High-Growth or Sunrise Industries: For emerging industries expected to expand rapidly and maintain high growth rates over an extended timeline, using a higher terminal growth rate is fully justified.
- Case Study Base: In the case of the Demonstration Investee Company, the perpetual terminal growth rate is assumed to be 5%.
The Perpetual Terminal Value Formula:
Terminal Value = [Total Free Cash Flow in Year 5 * (1 + g)] / (WACC - g)
(Where g is the terminal growth rate and WACC is the weighted average cost of capital discount rate).
4. Step 3: Determination of the Cost of Capital
4.1 The Role of WACC in DCF Discounting
To discount the projected Free Cash Flows and the Terminal Value back to the present day, we must determine the appropriate risk-adjusted rate. The standard metric is the Weighted Average Cost of Capital (WACC).
WACC acts as the hurdle rate, reflecting the blended cost of both equity and debt financing proportional to their weights in the firm's capital structure:
WACC = [We * Ke] + [Wd * Kd * (1 - t)]
Parameters Explained:
- We: Weight of Equity (ratio of equity to total capital in the capital structure).
- Ke: Cost of Equity (typically calculated using CAPM).
- Wd: Weight of Debt (ratio of debt to total capital in the capital structure).
- Kd: Cost of Debt (pre-tax cost of borrowing).
- t: The applicable corporate tax rate.
- Kd * (1 - t): The post-tax cost of debt.
4.2 Critical Rules for WACC Inputs
- The Debt Tax Shield: When calculating WACC, debt must always be considered on a post-tax basis. This is because interest payments are tax-deductible expenses, creating a tax shield that reduces the effective cost of borrowing for the firm.
- Debt Rate Source: The cost of debt is determined using either the average carrying cost of debt on the balance sheet or the marginal cost of borrowing currently available to the firm in the credit markets.
5. Step 4: Deriving Share Value from Enterprise Value
Once the Free Cash Flows (Step 1), Terminal Value (Step 2), and WACC (Step 3) are established, the final business valuation is calculated:
5.1 Computing Enterprise Value (EV)
The Enterprise Value represents the total, debt-free operating value of the business:
Enterprise Value = Sum of [Total Free Cash Flow in Year t / (1 + WACC)^t] + [Terminal Value / (1 + WACC)^5]
(For t from Year 1 to Year 5).
5.2 Transitioning to Equity Value
Both the DCF model and relative EBITDA multiples determine the Enterprise Value (operating value). To isolate the value belonging exclusively to the equity shareholders, all non-equity claims must be removed:
Equity Value = Enterprise Value - Outstanding Debt
Note on Debt: Outstanding debt can be deducted using its book value or current market value.
5.3 Calculating the Final Share Value
To determine the fair value of an individual equity share, divide the total Equity Value by the number of issued shares:
Value per Share = Equity Value / Number of Outstanding Equity Shares
6. Key Terms and Takeaways for Part 3
6.1 Key Terms
- Operating Cash Flow (OCF): The baseline cash generated from operations, calculated by adjusting Profit After Tax (PAT) for non-cash items and changes in working capital.
- Reinvestment Requirements: Capital commitments (Capex) and net working capital adjustments that are subtracted from Operating Cash Flow to arrive at Free Cash Flow.
- Terminal Value (TV): The estimated value of all cash flows beyond the explicit projection horizon, representing the perpetuity value of the business.
- WACC: The Weighted Average Cost of Capital; the blended discount rate that incorporates the post-tax cost of debt and the cost of equity.
- Enterprise Value (EV): The total debt-free, cash-free operating value of a business entity.
6.2 Key Exam-Relevant Takeaways
- The Post-Tax Debt Rule: In WACC calculations, debt must always be adjusted for tax: Kd * (1 - t). Failing to apply the tax shield is a major source of error in discounting models.
- Terminal Growth Rate Benchmark: Standard consolidated industries apply a terminal growth rate of 2% to 3% above inflation (generally 5% to 6%). High-growth "sunrise" industries justify a higher terminal growth rate due to long-term structural expansion.
- EV to Equity Deduction: DCF models yield Enterprise Value (EV). To find the Equity Value, always subtract the outstanding debt from the Enterprise Value.
