Comprehensive Study Notes: Chapter IV — Debt Securities

A debt security is a contract between the issuer (the borrowing company) and the lender (the investor) that allows the issuer to borrow a sum of money under pre-determined, legally binding terms. These terms define the structural and financial characteristics of the instrument.

1. Core Features of a Bond

Every standard bond or debt contract is defined by three fundamental features:

• The Principal: This is the actual sum of money borrowed by the issuer from the lender. It is also referred to as the nominal or face value of the bond and represents the amount that must be repaid.
• The Coupon: This is the periodic rate of interest paid by the borrower to the lender. The coupon is expressed as a percentage that is applied directly to the face value (or par value) of the bond to determine the periodic interest payment.
• The Maturity: This refers to the specific future date on which the debt contract expires and the borrower is legally required to repay the principal amount to the investor.

2. Varying Coupon Structures

Bonds can be structured with different coupon payment mechanisms to meet the cash-flow requirements of both issuers and investors:

A. Zero Coupon Bonds (Deep Discount Bonds)

• Coupon Mechanism: These bonds pay no periodic interest (zero coupons) during their life.
• Pricing: Instead of paying interest, they are issued at a discount to their face value and are redeemed at full par value upon maturity.
• Tenor Impact: When a zero coupon bond is issued with a very long maturity or tenor, the issue price is set at a steep discount to the final redemption value. Under these conditions, they are also referred to as Deep Discount Bonds.

B. Floating Rate Bonds

• Coupon Mechanism: Unlike fixed-coupon bonds, these instruments do not have a pre-determined interest rate that remains constant throughout the lifetime of the bond.
• Benchmark Linkage: The interest rate is re-set periodically based on a pre-specified external benchmark rate.

C. Deferred Interest Bonds

• Coupon Mechanism: These bonds allow the borrower to defer or postpone the payment of coupon interest during the initial years of the bond's tenor, typically for a period of 1 to 3 years.

D. Step-up Bonds

• Coupon Mechanism: The coupon rate on these bonds increases or "steps up" periodically over time. This structure ensures that the issuer's interest payment burden is lower in the initial years and increases as the business matures.

3. Structural Variations in Debt Securities

Issuers can embed specific options and redemption profiles into bonds to manage interest rate risk and repayment schedules:

A. Callable Bonds

• Issuer Option: A callable bond grants the issuer the right to alter the tenor of the bond by redeeming it before its scheduled maturity date.
• Market Rationale: If market interest rates decline, the issuer can exercise the call option to pay off the existing high-coupon debt and re-issue fresh bonds at a lower, more favorable interest rate.

B. Puttable Bonds

• Investor Option: A puttable bond provides the investor with the right to seek early redemption from the issuer before the official maturity date.
• Market Rationale: If market interest rates rise, investors can exercise the put option to sell their low-coupon bonds back to the issuer at par and reinvest those funds in newer bonds offering higher coupons.

C. Amortizing Bonds

• Redemption Profile: Unlike traditional bonds where the entire principal is repaid in a single lump sum at maturity, the principal of an amortizing bond is repaid gradually over the life of the instrument.
• Payment Structure: Each periodic payment made by the borrower to the investor contains a combination of both interest and a portion of the principal.

D. Asset-Backed Securities (ABS)

• Definition: These represent a specialized class of fixed-income products created by pooling together a group of underlying financial assets.
• Cash Flow: Bonds are then issued against this pool, representing direct participation in the cash flows generated by the underlying asset pool.

4. Detailed Classification of Debt Instruments

The debt market features multiple instruments categorized by the type of issuer, maturity period, and regulatory oversight:

Short-Term Money Market Instruments

A. Treasury Bills (T-Bills)

• Issuer: Issued by the Government of India to meet short-term borrowing needs.
• Tenors: Standard maturities are 91 days, 182 days, and 364 days.
• Issuance Method: T-Bills are issued through a competitive auction process managed by the Reserve Bank of India (RBI). Participating bidders include banks, mutual funds, insurance companies, provident funds, primary dealers, and financial institutions (FIs).
• Structure: They are typically structured and issued as zero-coupon bonds.

B. Collateralized Borrowing and Lending Obligation (CBLO)

• Collateral: Borrowing under CBLO is backed by government securities, which are held as collateral with the Clearing Corporation of India Ltd. (CCIL).
• Maturity & Structure: It is a discounted money market instrument with maturities ranging from 1 day up to 1 year.
• Usage: It is heavily utilized by banks to borrow short-term funds from mutual funds and insurance companies.

C. Certificates of Deposit (CD)

• Issuer: Issued by banks to meet their short-term funding requirements.
• Transferability: Unlike standard bank deposits, CDs involve the creation of a physical or electronic paper instrument, which makes them freely transferable before maturity.
• Liquidity: Despite being transferable, secondary market trading activity in CDs remains relatively low.

D. Commercial Paper (CP)

• Issuer: Issued by corporate entities or financial institutions to fund their short-term working capital requirements.
• Maturity: CPs can be issued for varying short-term tenors, ranging from a minimum of 7 days to a maximum of 1 year from the date of issue.

Long-Term Debt Instruments

E. Government Securities (G-Secs / Treasury Bonds)

• Purpose: Predominantly issued by the government to fund the national fiscal deficit.
• Benchmark Status: Government securities act as the pricing benchmark for corporate debt paper of similar maturities. Because government debt is considered risk-free, all corporate and private borrowers in the system must borrow at a premium or "spread" over the benchmark G-Sec rate.

F. Corporate Bonds

• Market Dominance: The secondary and primary markets for corporate bonds are highly dominated by private placements targeted at large institutional investors.
• Public Issue Regulations: When a company makes a public issue of debt securities, it is strictly regulated by the Securities and Exchange Board of India (SEBI). SEBI regulations mandate that any public issue of corporate debt must meet the following investor-protection requirements:
  1. The debt issue must be formally credit-rated by a registered agency.
  2. A qualified debenture trustee must be formally appointed.
  3. The company must create a Debenture Redemption Reserve (DRR).
  4. The company must create a secure charge on the assets of the company to back the debt.

5. Yield Measures for Debt Instruments

To evaluate the profitability and returns of a debt investment, investors use two key yield metrics:

A. Current Yield

The current yield is a basic measure that compares the annual coupon payment of a bond directly with its current market price. It does not account for capital gains, discount amortization, or the time value of money.

• Formula in Simple Line Format: Current Yield = (Annual Coupon / Market Price) * 100

• Practical Example: If a corporate bond carries an annual coupon of 12% (based on its par value) but is currently trading in the secondary market at a premium price of Rs. 109.50, the current yield is calculated as: Current Yield = (12 / 109.50) * 100 = 10.95 percent

B. Yield to Maturity (YTM)

• Definition: Every bond consists of a series of future cash flows (periodic coupon payments and the final principal repayment) that accrue from the date of acquisition until maturity or sale.
• Valuation Principle: According to the standard principles of financial valuation, the current price of a bond should equal the sum of the discounted value of all these future cash flows.
• YTM Calculation: The Yield to Maturity (YTM) is the specific internal rate of return (discount rate) that equates the total discounted value of these future cash flows exactly with the current market price of the bond.

6. Credit Risk and Credit Rating

The Concept of Credit Risk

The primary risk associated with investing in debt instruments is credit risk (or default risk). This is the risk that the borrower (issuer) may fail to honor their contractual obligations, either by defaulting on periodic interest (coupon) payments or failing to repay the principal amount upon maturity.

The Role of Credit Rating Agencies (CRAs)

• Evaluation: Credit rating agencies evaluate the creditworthiness of a borrower by conducting a thorough analysis of both qualitative and quantitative business and financial factors.
• Appraisal Process: This evaluation is conducted by industry experts who compile and analyze data sourced from the borrower as well as independent external sources.
• Rating Symbols: Based on this evaluation, the agency's rating committee assigns a specific credit rating symbol to the debt instrument. This symbol acts as an easily recognizable indicator of the issuer's ability and willingness to service their debt obligation.
• Regulatory Oversight: Credit rating agencies in India must be formally registered with SEBI and operate in strict compliance with the SEBI (Credit Rating Agencies) Regulations, 1999.
