Fixed-Income & Mortgages: Lecture Notes
0) Why the First Weeks Matter
Review of Foundational Concepts:
Time Value of Money (TVM): Understanding the value of money over time.
Pricing Loans, Bonds, and Notes: How these financial instruments are valued.
Principal vs. Interest: Distinguishing between the original amount borrowed and the cost of borrowing.
Learning Approach: Emphasizes repetition and practice, as these patterns are frequently encountered.
1) Fixed-Income vs. Equity (Big Picture)
Fixed-Income (Debt):
Represents contractual payments which include interest and principal.
Resides on the right side of the balance sheet under liabilities.
Equity:
Represents a residual claim; equity holders are paid only after debt obligations are met.
Risk/Return Relationship:
Senior, collateralized debt has less risk than junior debt.
Junior debt has less risk than equity.
This reduced risk for debt translates to a lower required return for lenders.
2) Key Characteristics of Fixed-Income
Coupon (Interest) Payments:
The periodic cash payments made to investors.
Serves as the "reward" or return for lending money.
Principal:
The original amount borrowed.
Reduces only when principal is repaid; interest payments do not decrease the principal balance.
Seniority:
Determines payoff priority: senior debt has priority over subordinated debt.
Senior debt is often secured by collateral, which can include real estate, inventory, receivables, or cash.
Default/Bankruptcy:
Debt holders have priority over equity holders in the event of default or bankruptcy.
Debt contracts typically include provisions such as:
Covenants: Conditions that borrowers must uphold.
Indentures: Formal legal contracts detailing the terms of the debt.
Dispute Resolution: Mechanisms for handling disagreements.
Limits on Further Borrowing: Restrictions on a borrower's ability to take on more debt.
3) Mortgage = Loan Secured by Real Property
A mortgage is specifically a loan where real property (residential or commercial) serves as collateral.
Loans secured by other types of collateral (e.g., a jet) are not referred to as mortgages.
4) Payment Frequencies and Period Setup
If payments are semiannual:
Number of Periods (N): Calculated as years \times 2 (e.g., for a 5-year loan, N = 5 \times 2 = 10 periods).
Periodic Rate (r_{periodic}): Calculated as annual \, rate / 2.
Example: 1,000,000 loan at 7\% APR, semiannual
Periodic rate = 7\% / 2 = 3.5\%.
First period interest (if opening principal = 1,000,000) = 0.035 \times 1,000,000 = 35,000
5) Three Repayment Structures to Know
A) Bullet (Interest-Only + Principal at Maturity)
Structure: Interest payments are made each period, and the entire principal is repaid in one lump sum ("bullet") at the end of the loan term.
Example (semiannual):
Periods 1-9: Interest payment of $35,000 each.
Final period (e.g., period 10): Payment of $35,000 (interest) + $1,000,000 (principal).
B) Level Principal
Structure: An equal amount of principal is repaid each period.
Consequence: Interest payments decline over time because the outstanding principal balance decreases.
Example (5 years, semiannual; 10 periods):
Principal repayment each period = $1,000,000 / 10 = 100,000.
Period 1:
Opening principal = $1,000,000
Interest = 3.5\% \times 1,000,000 = 35,000
Total payment = $100,000 (principal) + $35,000 (interest) = $135,000
Ending principal = $900,000
Period 2:
Opening principal = $900,000
Interest = 3.5\% \times 900,000 = 31,500
Total payment = $100,000 (principal) + $31,500 (interest) = $131,500
Ending principal = $800,000
Observation: Total payments decline over time because the interest component falls.
C) Level Debt Service (Level Payment / Annuity)
Structure: The total payment made each period remains constant.
Dynamic: Over time, the interest portion of the payment decreases, while the principal portion increases.
Calculation: Requires annuity mathematics or a financial calculator (using variables like rate, N for number of periods, and PV for present value to determine the payment, PMT).
Logic: Follows a similar table structure to other methods, but the total payment amount stays fixed.
6) Capital Structure & Financing Basics
Capital Structure: The mix of debt and equity used to finance an organization's assets; represents the right side of the balance sheet.
External Financing: Funding sourced from outside the firm, including debt and new equity issuance.
Internal Financing: Funding generated from within the firm, primarily through retained earnings (a portion of net income).
Example: If a project is financed with a 50% debt and 50% equity mix, and the loan amount (debt) is $1,000,000, then the total capitalization for the project is $2,000,000 (1,000,000 debt + 1,000,000 equity).
7) Capitalized Interest (Super Important)
Definition: If interest payments are not made currently (either by design or due to missed payments), the unpaid interest can be capitalized, meaning it is added to the principal balance.
Real-World Uses: Common in large projects (e.g., stadiums, bridges, power plants) during their construction or pre-operational phases when cash flows are not yet generated.
Consequences:
The principal amount grows by the capitalized interest.
Borrowers end up paying interest on interest in subsequent periods because the opening principal balance is higher.
Technical Default: If payments are underpaid or late, penalties (e.g., 1\%) may be assessed and also capitalized, further increasing the principal.
Transition: Once the asset becomes operational and generating cash flows, regular debt service (principal and interest payments) typically begins.
8) Credit Quality & Down Payments
Leverage in Mortgages: Mortgages are typically highly levered, meaning a large portion of the asset's value is financed by debt (e.g., 5–20% down payment implies 80-95% debt).
Credit Quality Impact: Borrowers with better credit quality are often required to make lower down payments, reflecting greater lender confidence in their ability to repay.
Example: For a $565,000 house with an 8\% down payment:
Equity (down payment) = 0.08 \times 565,000
Debt (mortgage) = 92\% of the house value.
9) Leverage & LBOs
Leverage: The use of debt to acquire assets.
It is a powerful strategy when the returns generated by the acquired assets exceed the cost of the debt.
Tax Shield: Interest payments are typically tax-deductible, which further lowers the effective cost of debt.
LBO (Leveraged Buyout):
A type of Mergers & Acquisitions (M&A) transaction that is financed predominantly by debt.
Optimal Conditions: Works best when the target company has large, predictable, and stable free cash flows, which are essential for servicing the high fixed debt obligations inherent in an LBO.
Tax Deductibility of Interest:
Lowers the after-tax cost of debt.
Can reduce the Weighted Average Cost of Capital (WACC) for a firm, up to a certain point (beyond which, increased financial risk outweighs the tax benefit).
Foundational Concepts for Mastery
Time Value of Money (TVM): Crucial for pricing loans, bonds, and notes.
Principal vs. Interest: Distinguish between the original borrowed amount and the cost of borrowing.
Learning emphasizes repetition and practice of these patterns.
Fixed-Income (Debt) vs. Equity
Fixed-Income: Represents contractual payments (interest + principal); sits on the right side of the balance sheet as liabilities.
Equity: Represents a residual claim, paid only after debt obligations are met.
Risk/Return Hierarchy: Senior, collateralized debt (lowest \, risk) < Junior debt < Equity (highest \, risk). Lower risk implies a lower required return for lenders.
Key Characteristics of Fixed-Income
Coupon Payments: Periodic cash payments (interest) to investors, acting as the 'reward' for lending.
Principal: The original amount borrowed; reduces only when explicitly repaid, not by interest payments.
Seniority: Determines payoff priority during default (senior debt has priority, often secured by collateral like real estate or inventory).
Default/Bankruptcy: Debt holders have priority over equity holders. Debt contracts include covenants, indentures, and dispute resolution mechanisms, often limiting further borrowing.
Mortgages
A mortgage is a loan specifically secured by real property (residential or commercial).
Payment Frequencies Setup
For semiannual payments:
Number of Periods (N): years \times 2
Periodic Rate (r_{periodic}): annual \, rate / 2
Example for a $1,000,000 loan at 7\% APR, semiannual: Periodic rate = 3.5\%, first period interest = $35,000
Three Repayment Structures
Bullet (Interest-Only + Principal at Maturity):
Only interest payments are made periodically.
The entire principal is repaid as a single lump sum ('bullet') at the loan's maturity.
E.g., for a $1,000,000 loan at 3.5\% periodic rate, periods 1-9 pay $35,000 interest; period 10 pays $35,000 (interest) + $1,000,000 (principal).
Level Principal:
An equal amount of principal is repaid each period.
Consequence: Interest payments decline over time because the outstanding principal balance decreases, leading to declining total payments.
E.g., for $1,000,000 over 10 periods, 100,000 principal is repaid each period. Period 1 total payment = $135,000 (100,000 principal + 35,000 interest on $1,000,000); Period 2 total payment = $131,500 (100,000 principal + 31,500 interest on $900,000).
Level Debt Service (Level Payment / Annuity):
The total payment made each period remains constant.
Over time, the interest portion decreases, and the principal portion increases within each fixed payment.
Requires annuity mathematics (e.g., using a financial calculator to determine PMT based on rate, N, and PV).
Capital Structure & Financing Basics
Capital Structure: The mix of debt and equity financing assets; the 'right side' of the balance sheet.
External Financing: Funds from outside the firm (debt, new equity issuance).
Internal Financing: Funds generated within the firm (retained earnings).
Example: $1,000,000 debt for a project with 50% debt/50% equity implies $2,000,000 total capitalization.
Capitalized Interest (Critical Concept)
Definition: Unpaid interest is added to the principal balance, increasing the total debt.
Real-World Use: Common in large projects (stadiums, power plants) during construction/pre-operational phases when cash flows are not yet generated.
Consequences: Leads to principal growth, and borrowers effectively pay interest on interest in subsequent periods.
Technical Default: Underpaid or late payments may incur penalties that are also capitalized.
Transition: Regular debt service begins once the asset is operational and generating cash flows.
Credit Quality & Down Payments
Leverage in Mortgages: Mortgages are typically highly levered (e.g., 5-20% down payment means 80-95% debt financing).
Credit Quality Impact: Borrowers with better credit usually require lower down payments.
Example: A $565,000 house with an 8\% down payment means 0.08 \times 565,000 equity and 92\% debt.
Leverage & LBOs
Leverage: Using debt to acquire assets; advantageous when asset returns exceed debt costs.
Tax Shield: Interest payments are tax-deductible, lowering the effective cost of debt and potentially reducing the Weighted Average Cost of Capital (WACC).
Leveraged Buyout (LBO): An M&A transaction largely financed by debt. Best suited for target companies with large, predictable, and stable free cash flows to service high debt obligations.
