1.4 Corporate Debt and Fixed Income Instruments

1.4 Corporate Debt and Fixed Income Instruments

Corporate financing in the Philippines involves balancing equity issuances with debt financing. When a corporation issues debt, it enters into a formal contractual borrower-lender relationship. Unlike equity investors who hold ownership rights, debt holders are creditors who possess a senior contractual claim on corporate cash flows and liquidation proceeds.

Domestic corporate fixed-income securities are regulated by the Securities and Exchange Commission (SEC) under the Securities Regulation Code (SRC, Republic Act No. 8799) and the Revised Corporation Code of the Philippines (RA 11232), with secondary trading executed primarily on the Philippine Dealing & Exchange Corp. (PDEx) platform.

Debt vs. Equity Financing: Legal and Capital Structure Dynamics

A corporation's capital structure represents the permanent financing mix of long-term debt, preferred stock, and common equity.

Capital Structure Trade-Offs
  ├── Corporate Debt (Creditor Claim):
  │     ├── Tax-Deductible Interest (NIRC Section 34)
  │     ├── Mandatory Fixed Legal Obligations (Default Risk)
  │     └── Senior Priority in Liquidation (No Equity Ownership)
  └── Equity Financing (Ownership Interest):
        ├── Non-Deductible Dividend Distributions
        ├── Discretionary Cash Payouts (Zero Default Risk)
        └── Residual Liquidation Priority (Dilution of Voting Control)

1. Tax Treatment and the Interest Tax Shield

Under the National Internal Revenue Code (NIRC), as amended by the Tax Reform for Acceleration and Inclusion (TRAIN) Law and the Corporate Recovery and Tax Incentives for Enterprises (CREATE) Act, interest paid on corporate debt is generally a tax-deductible operating expense (Section 34). In contrast, dividends paid to preferred or common stockholders are distributions of net income after corporate income tax and are not tax-deductible. This tax asymmetry makes debt a cost-effective financing mechanism for profitable corporations.

2. Legal Nature of the Claim and Financial Risk

• Mandatory Debt Service: Debt creates a strict legal obligation to pay interest and repay principal at maturity, regardless of whether the corporation operates at a profit or loss. Failure to service debt triggers contractual default, enabling creditors to accelerate principal repayment, enforce collateral liens, or initiate corporate rehabilitation under the Financial Rehabilitation and Insolvency Act of 2010 (FRIA, RA 10142).
• Equity Flexibility: Equity imposes no mandatory cash outflow; dividend declarations remain entirely at the discretion of the board of directors.

3. Impact on Corporate Control

Debt issuances do not dilute the voting control or ownership percentages of existing common stockholders. However, major lenders and bond indentures routinely impose restrictive covenants that constrain corporate management. These covenants include maintaining minimum debt service coverage ratios (DSCR), limiting capital expenditures, restricting additional debt issuances, and capping dividend distributions.

Statutory Authority for Bonded Indebtedness (Section 37)

Under Section 37 of Republic Act No. 11232, incurring, creating, or increasing bonded indebtedness is treated as a major corporate milestone. Because bonded debt places substantial long-term claims on corporate assets, the board cannot issue bonds unilaterally.

Statutory Approval Requirements for Bonds

1. Board Approval: A majority vote of the board of directors at a meeting duly assembled.
2. Shareholder Approval: The affirmative vote or written assent of stockholders representing at least two-thirds (2/3) of the outstanding capital stock at a regular or special meeting duly called for that purpose.
3. Prior Notice: Written notice of the proposed action and of the time and place of the meeting must be addressed to each stockholder.
4. SEC Registration: A certificate signed by corporate officers must be filed with the SEC, accompanied by formal registration under the Securities Regulation Code unless an exempt transaction applies.

Spectrum of Fixed Income Instruments in the Philippine Market

Philippine corporate debt securities fall across a broad spectrum of security backings, maturities, and investor protections.

Secured Debt Instruments

Secured bonds give creditors a legal lien against specific pledged collateral. If the issuer defaults, the bond trustee can seize and liquidate the collateral to satisfy bondholder claims.

• Mortgage Bonds: Secured by a formal first or junior mortgage lien on physical real estate, factory facilities, or operational land holdings of the issuing corporation. Because real property retains tangible residual value, mortgage bonds carry lower credit risk than unsecured debentures.
• Collateral Trust Bonds: Secured by financial assets deposited with an independent trustee (such as a commercial bank trust department). The pledged collateral typically consists of shares of stock or debt securities of subsidiaries or other investment holdings owned by the issuing corporation.
• Equipment Trust Certificates (ETCs): Common in transportation and heavy industry, ETCs are secured by specific movable physical equipment (such as commercial aircraft, passenger vessels, or cargo rail rolling stock). Under this trust structure, legal title to the equipment remains with the trustee until the corporation fully retires the debt.

Unsecured Debt Instruments

Unsecured bonds are backed only by the general creditworthiness, operational reputation, and cash-generating ability of the issuing corporation.

• Debentures: Unsecured long-term debt backed by the "full faith and credit" of the corporate issuer. Well-established, blue-chip conglomerates (such as Ayala Corporation or SM Prime Holdings) frequently issue debentures because their robust balance sheets attract investors without requiring asset pledges.
• Subordinated Debentures: Junior unsecured debt whose claims rank behind senior bank debt, mortgage bonds, and general debentures in corporate liquidation. In exchange for accepting higher credit risk and subordinated standing, investors require a higher coupon yield.
• Commercial Paper (CP): Short-term unsecured promissory notes issued by creditworthy corporations to finance short-term working capital needs (e.g., seasonal inventory buildup or payroll). Commercial paper in the Philippines has maturities of 365 days or less and is strictly regulated under the SEC's Rules on Registration of Commercial Paper (SRC Rules 8.1 and 12.1).

Convertible Bonds and Parity Calculations

A convertible bond is a hybrid fixed-income security that grants the bondholder the right, but not the obligation, to exchange the bond for a predetermined number of common shares of the issuing corporation.

Key Concepts and Core Mathematical Formulas

1. Conversion Price: The stated dollar or peso price at which common stock can be acquired through conversion.
2. Conversion Ratio: The exact number of common shares received upon converting one bond:

$\text{Conversion Ratio} = \frac{\text{Par Value of Bond}}{\text{Conversion Price}}$

1. Parity Price of Bond: The market price at which the bond is economically equivalent to the aggregate market value of the shares into which it converts:

$\text{Parity Price of Bond} = \text{Market Price of Common Stock} \times \text{Conversion Ratio}$

1. Parity Price of Stock: The stock price required to justify the current market price of the convertible bond:

$\text{Parity Price of Stock} = \frac{\text{Market Price of Bond}}{\text{Conversion Ratio}}$

Practical Calculation Example

A Philippine telecommunications company issues an 8% convertible bond with a par value of ₱1,000 and a conversion price of ₱25.00 per share.

• Step 1: Calculate Conversion Ratio $\text{Conversion Ratio} = \frac{\text{PHP } 1,000}{\text{PHP } 25.00} = 40 \text{ shares}$

• Step 2: Determine Parity Price of the Bond If the company's common stock is trading at ₱28.00 on the PSE: $\text{Parity Price of Bond} = \text{PHP } 28.00 \times 40 = \text{PHP } 1,120$

  • If the bond is trading at ₱1,080 in the market, it is trading below parity. An arbitrageur could buy the bond for ₱1,080, immediately convert it into 40 shares, and sell those shares on the PSE for ₱1,120, locking in a gross arbitrage profit of ₱40.

• Step 3: Downside Protection (Investment Floor) If the underlying stock plummets, the convertible bond will not fall to zero. It will trade based on its value as a straight bond paying an 8% coupon, known as its investment floor.

Credit Ratings and the Role of PhilRatings

In the Philippine capital market, institutional investors rely on credit rating agencies (CRAs) to evaluate default risk. Under SEC regulations, CRAs must be officially accredited by the Commission.

The premier domestic rating agency is the Philippine Rating Services Corporation (PhilRatings). PhilRatings assesses the issuer's capacity to service principal and interest on a timely basis, assigning credit ratings using standard scales.

Bond Pricing, Yield Dynamics, and PDEx Trading

Fixed-income securities in the Philippines trade based on yield rather than pure price. Corporate bonds and government Treasury bills and bonds are listed and traded electronically on the Philippine Dealing & Exchange Corp. (PDEx) platform.

The Inverse Price-Yield Relationship

Bond prices and market interest rates maintain an inverse relationship:

• When prevailing market interest rates rise, existing bond prices fall (to offer a competitive yield).
• When prevailing market interest rates fall, existing bond prices rise (bidding up the premium of fixed coupons).

Three Essential Yield Metrics

1. Nominal Yield (Coupon Rate): The fixed annual interest payout stated on the bond certificate, expressed as a percentage of par value (₱1,000 par): $\text{Annual Coupon Payment} = \text{Par Value} \times \text{Coupon Rate}$
2. Current Yield: The annual coupon payment divided by the current secondary market price of the bond: $\text{Current Yield} = \frac{\text{Annual Coupon Payment}}{\text{Current Market Price}}$
3. Yield to Maturity (YTM): The comprehensive internal rate of return earned by an investor who buys the bond at its current market price and holds it to maturity, factoring in all coupon payments plus the amortization of discount or premium.

The Fixed Income Seesaw (Yield Hierarchy)

Understanding the relative hierarchy of these yields across pricing environments is one of the most frequently tested concepts on capital market licensing exams:

Discount Bond (Price < Par):
  Nominal Coupon  <  Current Yield  <  Yield to Maturity (YTM)

Par Bond (Price = Par):
  Nominal Coupon  =  Current Yield  =  Yield to Maturity (YTM)

Premium Bond (Price > Par):
  Nominal Coupon  >  Current Yield  >  Yield to Maturity (YTM)

Practical Exam Traps and Regulatory Pitfalls

• Trap 1: Bond Indebtedness Voting Threshold. Incurring or increasing bonded indebtedness requires a 2/3 shareholder vote (Section 37), not a simple board majority or simple shareholder majority.
• Trap 2: The Discount Bond Yield Hierarchy. On a bond purchased at a discount (e.g., ₱920 for a ₱1,000 par bond), candidates must remember that YTM is always the highest yield metric, followed by current yield, with the nominal coupon rate being the lowest.
• Trap 3: Conversion Ratio Uses Par, Not Market Price. When calculating the conversion ratio for convertible bonds, always divide the par value (₱1,000) by the conversion price. Never divide the fluctuating secondary market price of the bond by the conversion price.
• Trap 4: Investment Grade Boundary. Candidates often mistakenly believe PRS A is the lowest investment grade. In the PhilRatings scale, PRS Baa is the lowest investment-grade rating; PRS Ba is the highest speculative rating.
