Capital Structure Review and Theories

Understanding the implications of various capital structure theories is crucial for corporate finance decisions.

Modigliani-Miller (M&M) Propositions

• Case I: Value of Levered Firm (VL) = Value of Unlevered Firm (VU)
  • Assumes a perfect world: no taxes, no bankruptcy costs, perfect information symmetry, competition, and no transaction costs.
  • Capital structure is irrelevant to firm value.
  • The cost of capital remains constant.
    • Adding cheaper debt increases equity risk (higher required return on equity).
    • This increase in equity cost perfectly offsets the benefit of cheaper debt, keeping the Weighted Average Cost of Capital (WACC) the same.
• Case II: VL = VU + Present Value of Tax Shield (DT)
  • Includes corporate tax,

The Three Sectors of Industry

• Primary Sector: Extracts and uses natural resources from the Earth.
• Secondary Sector: Manufactures goods using raw materials provided by the primary sector.
• Tertiary Sector: Provides services to consumers and other sectors of industry.

The three sectors are usually compared by two factors:

• The number of workers in each sector.
• The value of the output of goods and services.

Economic Systems

• Deindustrialization: The process involving a decline in the importance of the secondary manufacturing sector in an economy.
• Free Market Economy: An economy without government control over the factors of production; also known as a market economy.
• Monopoly: A business that controls the entire market

Chapter 3: Business Organizations

There are five main forms of business organizations in the private sector:

1. Sole Traders

Partnerships: A group or association between 2 and 20 people who... Continue reading "Business Organizations: Structures & Key Concepts" »

Municipal Bond Yield Calculations

Equivalent Taxable Yield (ETY)

A municipal bond carries a coupon rate of 6.00% and is trading at par.

Required Calculation 1: ETY for a 38% Tax Bracket

What would be the equivalent taxable yield of this bond to a taxpayer in a 38% combined tax bracket?

The formula for Equivalent Taxable Yield ($r$) is:

$$r = r_m / (1 - t)$$

• $r$: Equivalent Taxable Yield
• $r_m$: Municipal Bond Yield (6.00% or 0.06)
• $t$: Tax Rate (38% or 0.38)

Calculation:

$$0.06 / (1 - 0.38) = 0.096774 \rightarrow \mathbf{9.68\%}$$

Required Calculation 2: Municipal Yield Preference

An investor is in a 40% combined federal plus state tax bracket. If corporate bonds offer 7.75% yields, what yield must municipals offer for the investor to prefer them to corporate... Continue reading "Financial Calculations: Yields, Index Returns, and Security Pricing" »

Hedging with S&P 500 Index Futures

SIF hedging: NF = V_F(antiguo) = F_o x Z. NF (Number of contracts) = V_p (portfolio value) / (V_F x B_p) (Beta). With this hedge, risk is removed. If the index goes up, the profit in the portfolio will be offset by losses in SIFs contracts and vice versa.

Example: S&P 500 falls 5%:

• In the portfolio: R_p = B_p x (-5%) = -10% of a portfolio of $10M, resulting in $9M (Final Value).
• In the SIFS contracts: S_i = 980 (S&P 500 value given) x 0.95 (100% - 5%) = 931. F_i = 931 x (1 + 0.04 x 5/12 (next month timeframe)) = 946.52. V_F = NF x (F_i - F_o) x Z (250).
• Gain on futures: V_F(New) / Equity portfolio value.
• Outcome stock portfolio: 2 x (-5%) = -10%.
• Final Value portfolio: $10M - $1M + V_F(New).

Manufacturing Costs

Manufacturing costs include indirect materials, indirect labor, maintenance and repairs on production equipment, heat and light, property taxes, depreciation, and insurance on manufacturing facilities.

• Formula: Total Variable Cost (TVC) = Variable Cost per Unit × Number of Units Produced
• Fixed Costs: Expenses that remain constant regardless of production levels (e.g., rent, salaries, insurance, property taxes, loan payments).

Direct Costs

Direct Costs are expenses that can be directly attributed to a specific product, project, or activity associated... Continue reading "Manufacturing Cost Analysis and Financial Statement Formulas" »
