Capital Structure Arbitrage and Litigation Finance (CFA Level 1): Understanding Capital Structure Arbitrage, Analytical Frameworks and Structural Credit Models, and Role of Credit Default Swaps (CDS). Key definitions, formulas, and exam tips.
Picture this: You’re poring over the financial statements of a company that has multiple layers of debt, equity, and maybe even a few warrants thrown in for good measure. You notice that the bond prices seem oddly depressed relative to the firm’s equity valuation. At some point, you can’t help but think, “Wait, aren’t these two capital structure layers tied to the same underlying assets?” That’s basically the spark behind capital structure arbitrage—a strategy that aims to exploit relative mispricings between a company’s different capital layers.
In the meantime, there’s another corner of the alternative investments arena that’s been quietly gaining traction: litigation finance. This is where investors or specialized firms fund legal disputes in exchange for a share of any monetary award that might result. It’s a world that sits at the crossroads of law, risk management, and big potential returns—often uncorrelated with mainstream markets. Sounds intriguing, right?
Below, we’ll take a closer look at both capital structure arbitrage and litigation finance, unraveling each strategy’s mechanics, risk factors, and potential benefits to a well-diversified alternative investments portfolio.
Capital structure arbitrage is all about mispricing—how the payoff of a firm’s debt instruments might differ from the payoff implied by its equity. Let’s say you believe the equity is overpriced relative to the risk profile indicated by the firm’s outstanding debt. In that scenario, you might short the equity—which you expect to decline in price—and simultaneously go long on the debt (or derivatives that reference the debt). Alternatively, if you expect the equity to outperform relative to the firm’s debt, you might do just the opposite.
To keep us on the same page, here’s an illustrative mermaid diagram showing a simplified capital structure from senior debt all the way down to equity:

In theory, each layer of the capital structure compensates investors for the probability of default, recovery rates, and overall claim priority in liquidation. If the company’s credit risk changes, you’d expect yields (or prices) to adjust accordingly across these layers. But in practice, markets can be inefficient for quite a while, presenting an arbitrage opportunity.
One of the more popular theoretical underpinnings for capital structure arbitrage draws on structural credit models like the Merton model. In simple terms (though the math can get intense), the Merton model treats a company’s equity as a call option on its underlying assets. Why a call option? Because if the firm’s assets are worth more than its liabilities at maturity, then equity holders essentially “exercise” their right to the residual claim. If the assets are worth less, the equity holders lose out—like letting an out-of-the-money call option expire.
From an arbitrage perspective, if the equity market implies a certain volatility for the firm’s value (and thus a certain risk of default), but the credit markets (as reflected in bond prices or credit default swaps) imply something else entirely, you might have an opening. For instance, if bond prices are overly cheap relative to the implied volatility from the equity side, it could be a signal to go long on the bonds and short the equity. The difference between what the equity is “saying” about default risk and what the bond or CDS spreads are “saying” can be captured for a profit if you get it right.
Credit default swaps (CDS) are essential tools in capital structure arbitrage. A CDS is like an insurance contract on the firm’s debt. If the company defaults, the buyer of protection gets compensated by the seller of protection, typically receiving the par value of the bond in exchange for the defaulted instrument. The spread you pay to buy a CDS is a reflection of the market’s view of the firm’s credit risk.
In an arbitrage context, you might see that the equity is trading at an implied volatility that suggests a relatively low default likelihood, but the CDS spread is quite high, indicating the credit market sees things more pessimistically. So you could short the equity and buy the CDS protection if you believe the bond market’s perspective is more “correct.” Over time, if the position converges (e.g., the CDS spread narrows, or the equity price falls), you could capture that mispricing.
Of course, none of this is guaranteed. Markets can stay irrational longer than you might expect, or new information might emerge that changes the fundamental picture dramatically. Plus, the technicalities of short selling fees, CDS market liquidity, and margin requirements will all matter immensely.
Imagine a simple scenario:
An arbitrageur might short the common stock (anticipating a correction in stock price once the market acknowledges the credit risk) and go long on the subordinated bonds. If the firm’s fundamentals remain stable, it’s possible the bonds will rally and converge closer to par, while the overly optimistic equity price might correct. By capturing that spread convergence, the arbitrageur stands to profit.
This idea can be framed in a little table:
| Capital Structure Layer | Observed Pricing Signal | Potential Action |
|---|---|---|
| Equity (Common Stock) | Overvalued (high prices) | Short Common Stock |
| Subordinated Bonds | Undervalued (wide yield) | Go Long Subordinated Bonds |
Naturally, real-world positions can be far more complex, possibly involving multiple derivatives to hedge out top-level market risk while focusing on the idiosyncratic mispricing. But the general principle remains.
Now, let’s shift gears to an alternative investment approach that’s all about legal claims: litigation finance. If you’ve never encountered this strategy before, it can seem a bit out of left field—like, “Wait, you can invest in lawsuits?” But it’s actually been around for quite some time, particularly in the commercial sector.
Litigation finance refers to the practice of providing funding to plaintiffs (or sometimes law firms) to pursue legal cases in exchange for a portion of any settlement or judgment. The big draw? The returns on such investments often hinge on the legal merits of the case, the quality of representation, and the solvency of the defendant—factors that can be largely uncorrelated with what’s happening on Wall Street or in global commodity markets.
So, even if equity markets tumble or interest rates spike, a well-chosen legal claim might stay on track, unaffected by broader economic gyrations. For some investors, this uncorrelated return profile is gold.
Here’s a simplified mermaid diagram that shows a possible litigation finance flow:

B["Funding Agreement"] --> E["Potential Settlement/Judgment"]

While litigation finance can deliver uncorrelated alpha, it’s not free from risk. Some key considerations:
Because no one can predict a courtroom outcome with perfect accuracy, robust due diligence is paramount. Most litigation finance providers have teams of lawyers, investigators, and experts who pick apart the case to minimize the risk of a total loss.
One of the biggest questions swirling around litigation finance is: Does external funding encourage frivolous lawsuits? That’s something regulators watch closely. In many jurisdictions, disclosure requirements and professional conduct rules mandate that attorneys maintain control of legal strategy, thus mitigating the risk that a funder effectively “buys” the case and dictates proceedings.
There’s also the question of conflicts of interest. For instance, if a funder exerts undue influence on a plaintiff to settle (or not to settle) for the sake of maximizing the funder’s return, is that in the plaintiff’s best interest? It’s a delicate balancing act, and some jurisdictions require explicit disclosures to ensure transparency.
From a CFA Institute Code of Ethics standpoint, it’s crucial that any alternative investment professional connect the dots between investor obligations (i.e., fairness, loyalty, and prudence) and the well-being of the party receiving the funding. Overstepping or ignoring these aspects can introduce major reputational and legal risks.
It might help to compare capital structure arbitrage and litigation finance with more traditional alternative strategies, such as private equity or standard hedge fund approaches.
| Strategy | Primary Focus | Main Sources of Return | Correlation |
|---|---|---|---|
| Capital Structure Arbitrage | Corporate debt vs. equity | Price convergences in capital stack | Moderate to Low with broad eq. |
| Litigation Finance | Legal claims & settlements | Legal judgments/settlements | Typically Low |
| Private Equity | Company ownership (long term) | Firm growth, exit multiples | Often Linked to eq. markets |
| Hedge Funds (Long/Short) | Broad range of instruments | Leverage & alpha on mispricings | Varied across strategies |
One key difference is that litigation finance is highly illiquid—cases can run for years, and you either get a payoff (often a big payoff) if the claim is successful or walk away with nothing if the suit fails. It’s a binary-like risk that requires skillful underwriting. In capital structure arbitrage, daily pricing for bonds, stocks, and CDS typically allows for more dynamic entry and exit strategies, though liquidity can still be an issue for certain distressed bonds or niche credit default swaps.
Some investors allocate to both capital structure arbitrage and litigation finance for a more holistic alternative investments exposure. The idea is that these strategies can offer returns not strongly tied to equity market movements or interest rate shifts. In times when equities and bonds might both be under pressure, a successful litigation finance portfolio might still produce healthy returns.
At the same time, these strategies can be complex. Brokerage fees for short positions, the cost of CDS, potential margin calls, and the possibility of losing your entire investment in an unsuccessful legal case—these are not for the faint of heart. Using a robust risk management framework—and possibly a dedicated team with the right expertise—is absolutely essential.
I remember a friend describing their first capital structure arbitrage trade with a mixture of excitement and sheer terror: “I’m long this weird subordinated bond, short the common stock, and it’s like I’m waiting for the market to realize what I believe is so obvious.” The convergence took longer than they expected, but eventually, they saw a tidy gain. That’s a microcosm of the patience and conviction you sometimes need in these positions.
As for litigation finance, I’ve met a few attorneys-turned-investment-managers who said they loved bridging the gap between financial structuring and the intricacies of legal battles. But they also warned me that the underwriting process demands a ton of effort—like a forensic team going through a company’s books, except you’re parsing through entire court records, witness depositions, expert analysis, and potential appellate processes. Patience and thoroughness rule the day, because if you skip steps, you can land in a world of litigation trouble—literally.
