Wal-Mart's Use of Interest Rate Swaps Custom Case Solution & Analysis

Evidence Brief

1. Financial Metrics

• Long term debt: 27.1 billion dollars as of fiscal year end 2007.
• Interest expense: 1.4 billion dollars for the 2007 period.
• Commercial paper outstanding: Approximately 4.5 billion dollars.
• Interest rate swap notional amount: 12.1 billion dollars total.
• Fixed to floating ratio: 52 percent fixed and 48 percent floating after accounting for swaps.
• Credit rating: AA plus from Standard and Poor and Aa2 from Moody.
• Target ratio: The treasury department aims for a 50-50 split between fixed and floating rate debt.

2. Operational Facts

• Treasury function: Centralized at the corporate headquarters in Bentonville, Arkansas.
• Swap type: Predominantly receive-fixed and pay-floating interest rate swaps.
• Counterparties: Large global financial institutions with high credit ratings.
• Maturity profile: Debt maturities range from 1 to 30 years to avoid refinancing concentration.
• Accounting treatment: Swaps are designated as fair value hedges under FAS 133 regulations.

3. Stakeholder Positions

• Tom Schoewe (CFO): Prioritizes the reduction of interest expense to support the low cost leadership strategy of the firm.
• Charles Holley (Treasurer): Focuses on maintaining liquidity and managing the mix of debt to ensure financial flexibility.
• Shareholders: Expect consistent earnings growth and minimal volatility from non-operational items like interest charges.
• Financial Institutions: Serve as swap counterparties and providers of credit lines.

4. Information Gaps

• Specific credit spreads for individual swap counterparties are not detailed.
• The exact sensitivity of the earnings per share to a 100 basis point move in LIBOR is not explicitly quantified.
• Internal limits for counterparty concentration are not disclosed in the text.

Strategic Analysis

1. Core Strategic Question

• Should Walmart maintain its 50-50 fixed-to-floating debt ratio or shift toward more floating rate debt to capitalize on declining interest rates while risking higher volatility?
• Does the interest expense savings generated by swaps justify the increased exposure to credit market instability?

2. Structural Analysis

The use of interest rate swaps is a direct extension of the cost leadership strategy of Walmart. By converting fixed-rate bonds into floating-rate obligations, the company aligns its interest costs with the current market environment. In a downward sloping or flat yield curve environment, this typically results in immediate interest expense savings. However, the reliance on the London Interbank Offered Rate (LIBOR) introduces a basis risk where the cost of debt may rise even if the Federal Funds rate remains low, particularly during credit crunches.

3. Strategic Options

Option A: Aggressive Floating Strategy (60 percent floating)

• Rationale: Capture maximum savings as the Federal Reserve cuts rates to stimulate the economy.
• Trade-offs: Increases earnings volatility and exposure to sudden spikes in short-term rates.
• Resources: Requires active monitoring by the treasury team and increased swap capacity from banks.

Option B: Conservative Fixed Strategy (70 percent fixed)

• Rationale: Lock in long-term funding at historically low coupon rates to protect against future inflation.
• Trade-offs: Results in higher immediate interest expense compared to floating options.
• Resources: Requires issuing new long-term bonds and terminating existing swap positions.

Option C: Balanced Dynamic Hedging (Current 50-50 target)

• Rationale: Maintains a neutral posture that balances cost savings with risk mitigation.
• Trade-offs: May miss significant savings if rates stay low for an extended period.
• Resources: Requires periodic rebalancing of the swap portfolio.

4. Preliminary Recommendation

Walmart should maintain the 50-50 split but shift the composition of its floating debt. The company should reduce reliance on standard swaps and increase the use of commercial paper for short-term needs. This preserves the low interest cost while reducing the long-term counterparty risks associated with decade-long swap contracts. The current market volatility suggests that certainty of capital access is becoming more valuable than marginal basis point savings.

Implementation Roadmap

1. Critical Path

• Month 1: Conduct a stress test on the current debt portfolio against a 200 basis point spike in LIBOR.
• Month 1: Review all ISDA agreements for credit-triggering events or collateral requirements.
• Month 2: Execute new receive-fixed swaps to offset any maturing floating rate obligations, maintaining the 50 percent target.
• Month 3: Diversify counterparty exposure by adding two additional high-rated international banks to the swap panel.

2. Key Constraints

• Counterparty Credit Risk: The ability of banks to honor swap payments if a systemic financial crisis occurs.
• Accounting Complexity: Ensuring all swaps meet the strict hedge accounting criteria to avoid income statement volatility.
• Market Liquidity: The availability of deep markets for long-dated swaps during periods of economic uncertainty.

3. Risk-Adjusted Implementation Strategy

The implementation will prioritize liquidity over pure cost optimization. Treasury will establish a floor for floating rate exposure to ensure that a sudden drop in rates does not leave the company paying above-market fixed coupons. Contingency plans include a pre-approved shelf registration for 5 billion dollars in fixed-rate bonds if the swap market becomes illiquid or if counterparty credit default swap spreads widen beyond 150 basis points.

Executive Review and BLUF

1. BLUF

Walmart must maintain its 50-50 fixed-to-floating debt ratio but pivot toward shorter-duration instruments. The current strategy of using interest rate swaps successfully reduced interest expense by millions, supporting the low-price business model. However, the brewing credit instability of 2007 makes counterparty risk a primary concern. The company should not increase floating exposure beyond 50 percent. Savings from lower rates are secondary to the risk of a frozen credit market. Financial flexibility is the priority.

2. Dangerous Assumption

The single most dangerous assumption is that LIBOR will remain highly correlated with the Federal Funds rate. In a credit crisis, LIBOR can spike due to bank risk even as the central bank lowers rates, which would cause the interest expense of Walmart to rise exactly when the economy is weakening.

3. Unaddressed Risks

• Counterparty Contagion: A failure of a major investment bank could lead to the immediate termination of billions in swaps, forcing Walmart to recognize fair value losses and find replacement hedges in a distressed market.
• Rating Downgrade: A downgrade of the credit rating of Walmart would increase the cost of future swaps and potentially trigger collateral calls under existing ISDA agreements.

4. Unconsidered Alternative

The team failed to consider the issuance of inflation-linked debt. Given the massive scale of the company and its exposure to consumer spending, inflation-protected securities could provide a natural hedge against rising operating costs that swaps do not address. This would diversify the investor base and provide a hedge that is not dependent on bank counterparty performance.
