Welcome to the World of Credit Risk!

In our previous Fixed Income sessions, we focused on interest rates and bond prices. But there is another massive piece of the puzzle: Credit Risk. Simply put, credit risk is the "will I get my money back?" factor. Whether you are lending $20 to a friend or $20 million to a corporation, you want to know if they can and will pay you back. In this chapter, we will learn how to measure that risk, how to rank different types of debt, and how professional analysts decide who is a "safe" borrower and who isn't.

1. Defining Credit Risk: The Basics

Credit risk is the risk of loss resulting from a borrower's failure to make full and timely payments of interest and/or principal. When we talk about credit risk, we are actually looking at two specific components:

A. Default Risk (Probability of Default - POD): This is the likelihood that the borrower will fail to meet their legal obligation to pay. Think of this as the "Yes/No" question: Will they miss a payment?

B. Loss Severity (Loss Given Default - LGD): If the borrower does default, how much will you actually lose? Usually, you don't lose everything. You might get 40 cents back for every dollar owed. This portion you get back is called the Recovery Rate.

The relationship is simple: \( \text{Loss Severity} = 1 - \text{Recovery Rate} \).

The Expected Loss Formula

To calculate how much money you expect to lose on average, use this formula:
\( \text{Expected Loss} = \text{Probability of Default} \times \text{Loss Given Default (in \$ terms)} \)

\n\n

Example: You lend \$1,000 to a company. There is a 5% chance they will default. If they do, you expect to recover 40% of your money.
1. Recovery Rate = 40%
2. Loss Severity = 100% - 40% = 60%
3. Expected Loss = \( 5\% \times (60\% \times \$1,000) = 0.05 \times \$600 = \$30 \).

Quick Review: Default Risk is about the chance of failing; Loss Severity is about the pain of failing.

It's not just about total default. Investors also worry about:

Spread Risk: Even if a company doesn't default, the "extra" interest they pay (the Credit Spread) can change. If the market thinks the company is getting riskier, the spread widens, and the bond's price drops. This consists of Downgrade Risk (getting a lower credit rating) and Market Liquidity Risk (not being able to sell the bond quickly at a fair price).

3. Seniority Rankings: The "Pecking Order"

If a company goes bankrupt, not everyone is treated equally. This is known as Capital Structure. Imagine a ladder where the people at the top get paid first, and the people at the bottom get whatever is left (if anything!).

The Typical Ranking (Highest to Lowest Priority):

1. First Lien Loan (Senior Secured): Backed by specific collateral (like a building or factory).
2. Second Lien Loan (Secured): Also backed by collateral, but they are second in line.
3. Senior Unsecured: No specific collateral, but still high in the priority list. This is the most common type of corporate bond.
4. Senior Subordinated: Lower priority.
5. Subordinated: Even lower.
6. Junior Subordinated: The bottom of the debt ladder.

Memory Aid: Think of "Pari Passu." This is a fancy Latin term meaning "on equal footing." All creditors within the same class (e.g., all Senior Unsecured holders) have the same priority of claim.

Key Takeaway: Higher seniority means lower Loss Severity. If you are a Senior Secured holder, your recovery rate will be much higher than a Subordinated holder.

4. Credit Ratings: The Grades

Rating agencies like Moody’s, S&P, and Fitch give companies "grades."

Investment Grade (IG): High quality. (S&P: AAA down to BBB-; Moody’s: Aaa down to Baa3).
Non-Investment Grade (High Yield / Junk): Higher risk. (S&P: BB+ and below; Moody’s: Ba1 and below).

Common Mistake to Avoid: Don't assume ratings are permanent! Agencies can be slow to react. This is why "Cross-over" bonds (those moving between IG and High Yield) often see massive price swings.

Did you know? "Notching" is when a rating agency gives a specific bond a different rating than the company as a whole. For example, a company might be rated A, but their subordinated debt is notched down to A- because it is riskier.

5. Credit Analysis: The 4 Cs

Don't worry if this seems like a lot to memorize. Just remember the 4 Cs of credit analysis. This is the framework used to evaluate a borrower's creditworthiness.

1. Capacity: The ability of the borrower to pay. We look at the industry structure, the company's competitive position, and financial ratios.
2. Collateral: The quality and value of the assets backing the debt. If things go wrong, what can the lender seize?
3. Covenants: The "rules" written into the bond contract. Affirmative covenants say what the company must do (like pay taxes). Negative covenants say what the company cannot do (like take on too much extra debt).
4. Character: The integrity and track record of management. Do they have a history of treating bondholders fairly?

6. Financial Ratios in Credit Analysis

In the "Capacity" section of the 4 Cs, we use two main types of ratios:

A. Leverage Ratios (How much do they owe?)

1. Debt / Capital: Total debt divided by total capital (Debt + Equity).
2. Debt / EBITDA: A very popular ratio. It tells us how many years of current earnings it would take to pay off the debt.

B. Coverage Ratios (Can they pay the interest?)

1. EBITDA / Interest Expense: High numbers are better! It means the company earns many times more than its interest bill.
2. EBIT / Interest Expense: A more conservative version because it subtracts depreciation/amortization.

Quick Review: High Leverage = Bad. High Coverage = Good.

7. Yield Spreads and the Credit Cycle

The Yield Spread is the difference between the yield on a corporate bond and a "risk-free" government bond of the same maturity.
\( \text{Yield Spread} = \text{Liquidity Premium} + \text{Credit Spread} \)

Market Conditions:
- Economic Boom: Spreads usually narrow (tighten). Everyone is making money, so the risk of default feels lower.
- Economic Recession: Spreads widen. Investors get scared and demand more interest to compensate for the higher risk of default.

Key Takeaway: If you expect the economy to improve, you want to buy corporate bonds before the spreads narrow. If you expect a recession, you might want to stick to government bonds!

Summary and Final Tips

• Credit Risk = Default Risk + Loss Severity.
• Seniority determines who gets paid first in a liquidation.
• The 4 Cs (Capacity, Collateral, Covenants, Character) are your roadmap for analysis.
• Spreads widen when the economy is bad and narrow when it's good.
• Investment Grade ends at BBB- (S&P) or Baa3 (Moody’s). Anything below is "Junk" or High Yield.

Congratulations! You've just covered the core pillars of Credit Risk. Keep these concepts in mind, and you'll be well-prepared for the Fixed Income section of the exam!
