Time Value of Money
The time value of money (TVM) is one of the foundational concepts in corporate finance. It posits that a dollar today is worth more than a dollar in the future due to its potential earning capacity.
Key Principles of TVM
1. Present Value (PV): The current worth of a future sum of money or stream of cash flows given a specified rate of return. PV can be calculated using the formula:
\[
PV = \frac{FV}{(1 + r)^n}
\]
where:
- \(FV\) = Future Value
- \(r\) = interest rate
- \(n\) = number of periods
2. Future Value (FV): The value of a current asset at a future date based on an assumed rate of growth. The formula for FV is:
\[
FV = PV \times (1 + r)^n
\]
3. Annuities: A series of equal payments made at regular intervals. The present value of an annuity can be calculated using the formula:
\[
PV = C \times \left(\frac{1 - (1 + r)^{-n}}{r}\right)
\]
where \(C\) is the payment amount, \(r\) is the interest rate, and \(n\) is the total number of payments.
4. Perpetuities: A type of annuity that lasts forever. The present value of a perpetuity is calculated as:
\[
PV = \frac{C}{r}
\]
Risk and Return
In corporate finance, the relationship between risk and return is crucial. Investors require compensation for taking on additional risk, and this is reflected in the expected returns.
Understanding Risk
1. Types of Risk:
- Systematic Risk: Risk inherent to the entire market or market segment. This type cannot be eliminated through diversification.
- Unsystematic Risk: Risk that is unique to a specific company or industry. This risk can be mitigated through diversification.
2. Measuring Risk:
- Standard Deviation: A measure of the amount of variation or dispersion in a set of values. A higher standard deviation indicates a higher risk.
- Beta: A measure of a stock's volatility in relation to the overall market. A beta greater than one indicates higher risk and potential return.
Expected Return
The expected return on an investment is calculated using the formula:
\[
E(R) = \sum (p_i \cdot r_i)
\]
where \(p_i\) is the probability of state \(i\) occurring, and \(r_i\) is the return in state \(i\).
Capital Budgeting
Capital budgeting is the process of planning and managing a company's long-term investments. It involves evaluating potential major projects or investments to determine their value to the firm.
Key Steps in Capital Budgeting
1. Identifying Potential Investments: Gather a list of potential projects that align with the company's strategic goals.
2. Estimating Cash Flows: Forecast the expected cash inflows and outflows associated with each project.
3. Evaluating Projects:
- Net Present Value (NPV): The difference between the present value of cash inflows and the present value of cash outflows over a period of time. A positive NPV indicates that the project is expected to generate value.
- Internal Rate of Return (IRR): The discount rate that makes the NPV of all cash flows from a particular project equal to zero. A project is considered acceptable if its IRR exceeds the required rate of return.
- Payback Period: The time it takes for an investment to generate an amount of cash inflows sufficient to recover the initial investment cost.
Tools and Techniques
- Profitability Index: A ratio of the present value of cash inflows to the initial investment. A profitability index greater than one indicates a potentially worthwhile investment.
- Scenario Analysis: Examining potential future events by considering alternative possible outcomes (e.g., best-case, worst-case).
- Sensitivity Analysis: Assessing how sensitive an investment's NPV is to changes in key assumptions.
Financial Markets
Financial markets play a critical role in corporate finance by providing mechanisms for companies to raise capital and investors to place their funds.
Types of Financial Markets
1. Capital Markets: Where long-term debt or equity securities are bought and sold. This includes the stock market and bond market.
2. Money Markets: Where short-term borrowing and lending occur, typically involving instruments with maturities of one year or less.
3. Derivatives Markets: Where financial instruments like options and futures are traded, allowing for risk management and speculation.
Functions of Financial Markets
- Price Discovery: Establishing the price of financial assets through supply and demand.
- Liquidity: Providing investors the ability to buy and sell securities easily.
- Risk Management: Offering various instruments to hedge against financial risks.
Cost of Capital
The cost of capital represents the opportunity cost of making a specific investment rather than investing the same funds in comparable financial securities. It is crucial for making informed investment decisions.
Components of Cost of Capital
1. Cost of Debt: The effective rate that a company pays on its borrowed funds. This cost can be calculated using the formula:
\[
K_d = \frac{I(1 - T)}{P}
\]
where \(I\) is interest payments, \(T\) is the tax rate, and \(P\) is the total debt.
2. Cost of Equity: The return required by equity investors, which can be estimated using the Capital Asset Pricing Model (CAPM):
\[
K_e = R_f + \beta (R_m - R_f)
\]
where \(R_f\) is the risk-free rate, \(R_m\) is the expected market return, and \(\beta\) is the stock's volatility relative to the market.
3. Weighted Average Cost of Capital (WACC): The average rate that a company is expected to pay to finance its assets, calculated as:
\[
WACC = \frac{E}{V} K_e + \frac{D}{V} K_d (1 - T)
\]
where:
- \(E\) = market value of equity
- \(D\) = market value of debt
- \(V\) = total market value of the company’s financing (equity + debt)
