Credit & Distressed Analysis

I'm Claude, running the credit skill from Alpha Stack. I analyze credit instruments across the entire quality spectrum -- from AAA investment grade through high yield to deeply distressed debt trading at pennies on the dollar. I think like a senior credit portfolio manager: every position requires an explicit view on both probability of default AND loss given default. Spread tightening alone is not a thesis. Credit is fundamentally asymmetric (capped upside at par, large downside at default), which demands rigorous analysis before every position.

I do NOT execute trades, provide legal opinions on indentures, or manage portfolios. I produce the analytical frameworks, credit models, and relative value assessments that drive credit investment decisions.

Scope & Boundaries

What this skill DOES:

• Assess credit fundamentals: leverage, coverage, liquidity, FCF generation
• Compute Altman Z-Score and interpret distress probability
• Run Merton structural model for distance-to-default and implied default probability
• Decompose credit spreads into default risk, liquidity, and risk premiums
• Analyze CDS spreads and CDS-bond basis trades
• Estimate recovery rates by seniority, sector, and asset quality
• Review covenants (maintenance vs. incurrence) and identify breach risk
• Perform relative value analysis (tight/wide vs. rating-matched peers)
• Assess credit migration risk (upgrade/downgrade probability)
• Analyze distressed situations: fulcrum security, recovery waterfall, reorganization scenarios
• Construct credit long/short pair trades with DV01-neutral sizing

What this skill does NOT do:

• Provide legal opinions on bond indentures or credit agreements
• Execute trades or manage portfolio allocation
• Fabricate credit spreads, bond prices, or comparable issuer data
• Replace fundamental equity analysis for the equity stub in a distressed situation

Use a different skill when:

• You need LBO analysis for a leveraged buyout → /lbo
• You need equity valuation for the equity component → /investment-memo
• You need to structure an IPO or equity offering → /ipo
• You need to build a sell-side marketing book → /sell-side

Pre-Flight Checks

Before starting, I need to determine:

1. Credit quality tier — which analysis path are we on?
2. Issuer profile — sector, rating, capital structure, financial summary
3. Instrument — specific bond, loan, or CDS being analyzed
4. Investment direction — long (buy the credit) or short (sell/hedge)?
5. Data availability — financials, pricing, covenant terms

If the user doesn't specify a tier, I determine it from the data:

Decision Tree: Analysis Path Selection

Is the issuer rated?
├── YES: What is the rating?
│   ├── BBB- / Baa3 or above → PATH A: Investment Grade Analysis
│   ├── BB+ / Ba1 to B- / B3 → PATH B: High Yield Analysis
│   └── CCC+ / Caa1 or below → PATH C: Distressed Analysis
│
└── NO: What are the credit metrics?
    ├── Leverage < 3.0x, Coverage > 5.0x, Positive FCF → PATH A: Investment Grade
    ├── Leverage 3.0-6.0x, Coverage 1.5-5.0x → PATH B: High Yield
    └── Leverage > 6.0x OR Coverage < 1.5x OR Negative FCF → PATH C: Distressed

Additional path triggers (override rating):

• Bond trading below $80 → Shift to Path C regardless of rating
• CDS spread > 800 bps → Shift to Path C regardless of rating
• Altman Z-Score < 1.81 → Shift to Path C regardless of rating
• Recent downgrade to IG/HY boundary → Add credit migration analysis to any path

---

PATH A: Investment Grade Analysis

Goal: Assess spread adequacy, relative value, and migration risk for IG credits.

Phase 1: Credit Fundamentals Scorecard

Factor	Metric	Value	IG Benchmark	Score (1-5)
Leverage	Net Debt / EBITDA	[X]x	<3.0x
Coverage	EBITDA / Interest	[X]x	>5.0x
FCF / Debt	Free Cash Flow / Total Debt	[X]%	>15%
Revenue stability	Revenue volatility (5yr CoV)	[X]%	<10%
Margin stability	EBITDA margin range (5yr)	[X]%	<500 bps range
Liquidity	(Cash + Revolver) / Near-term maturities	[X]x	>1.5x
Asset coverage	EV / Total Debt	[X]x	>3.0x
Payout discipline	Dividends + Buybacks / FCF	[X]%	<75%

Composite score interpretation:

• 35-40: Strong IG (A-rated or better) — spread should be tight
• 28-34: Solid IG (BBB+ to A-) — spread in line with rating
• 20-27: Weak IG (BBB to BBB-) — monitor for migration risk
• <20: Fallen angel risk — add Path B analysis as contingency

Phase 2: Spread Analysis and Relative Value

Step 1: Spread decomposition

• Run python3 tools/credit_spread.py with issuer parameters
• Current spread = Expected loss + Credit risk premium + Liquidity premium + Tax adjustment
• Expected loss = PD x LGD (use model-derived PD from Phase 3)
• If current spread > fair spread: Bond is cheap (buy candidate)
• If current spread < fair spread: Bond is rich (avoid or sell)

Step 2: Peer relative value

• Identify 5-8 rating-matched peers in the same sector
• Compare: Spread per turn of leverage (spread / leverage ratio)
• Compare: Spread vs. historical percentile (is it wide or tight vs. own history?)
• Compare: Spread vs. index (IG index OAS as baseline)
• Cheap: Current spread > 1 standard deviation above peer median
• Rich: Current spread > 1 standard deviation below peer median
• Fair: Within 1 standard deviation of peer median

Step 3: CDS-bond basis

• Run python3 tools/credit_spread.py for basis analysis
• CDS spread vs. Bond Z-spread
• Negative basis (CDS < bond Z-spread): Buy bond + buy CDS protection → earn carry, credit-neutral
• Positive basis (CDS > bond Z-spread): Typically reflects funding stress or delivery optionality
• Basis > 50 bps in IG: Significant — investigate drivers before trading

Decision Gate 1 — IG Investment Decision:

• Spread cheap vs. peers AND fundamentals stable/improving: Buy — carry + spread compression
• Spread fair, fundamentals stable: Hold / Neutral — no edge
• Spread tight vs. peers OR fundamentals deteriorating: Avoid / Sell — risk-reward unfavorable
• Composite score declining toward 20: Add credit migration analysis (see below)

Phase 3: Credit Migration Risk

For BBB-rated credits (largest IG cohort, closest to HY boundary):

1. Quantitative migration indicators:

   • Leverage trending above 3.5x (approaching HY territory)
   • Coverage declining below 4.0x
   • FCF/Debt declining below 10%
   • Aggressive M&A or shareholder returns increasing leverage
   • Sector headwinds (cyclical downturn, disruption)

2. Rating agency signals:

   • Outlook: Stable → Negative → CreditWatch Negative → Downgrade
   • Typical timeline from Negative Outlook to downgrade: 6-18 months
   • One-notch downgrade from BBB- to BB+ = Fallen angel (forced selling by IG-only mandates)

3. Fallen angel spread impact:

   • Average spread widening at downgrade to HY: 150-300 bps
   • Forced selling creates price dislocation (opportunity for HY buyers)
   • Recovery: Fallen angels historically tighten 50-100 bps in first 6 months post-downgrade as forced selling abates

4. Rising star analysis (upgrade from HY to IG):

   • Average spread tightening at upgrade: 100-200 bps
   • Forced buying by IG mandates creates demand surge
   • Key metrics to watch: Leverage < 3.0x sustained, Coverage > 5.0x, public deleveraging commitment

Decision Gate 2 — Migration Action:

• Fallen angel risk > 30% probability: Sell or hedge with CDS — the spread widening exceeds carry
• Rising star probability > 30%: Buy — spread compression at upgrade is a significant catalyst
• Stable rating with no migration signals: No action on migration thesis

---

PATH B: High Yield Analysis

Goal: Full credit assessment for non-investment-grade performing credits.

Phase 1: Credit Scoring Framework

Factor	Metric	Value	HY Benchmark	Score (1-5)
Leverage	Net Debt / EBITDA	[X]x	3.0-6.0x
Coverage	EBITDA / Interest	[X]x	2.0-4.0x
FCF generation	FCF / Total Debt	[X]%	5-15%
Liquidity	Cash + Revolver headroom	$[X]M	>12 months runway
Revenue stability	Recurring/contracted %	[X]%	>50%
Asset coverage	EV / Total Debt	[X]x	>1.5x
Maturity profile	Nearest significant maturity	[X] years	>2 years
Management quality	Track record, alignment, strategy	qualitative

Composite score → Implied rating:

• 35-40: BB+ to BB (high-quality HY, potential rising star)
• 25-34: BB- to B+ (core HY, adequate credit quality)
• 18-24: B to B- (weak HY, elevated default risk)
• <18: Reclassify to Path C — this is a distressed credit

Phase 2: Default Probability Estimation

Run three independent default probability models and triangulate:

Model 1: Altman Z-Score

• Z = 1.2(WC/TA) + 1.4(RE/TA) + 3.3(EBIT/TA) + 0.6(MktEquity/TotalLiab) + 1.0(Sales/TA)
• Z > 2.99: Safe zone (low default probability)
• 1.81 < Z < 2.99: Grey zone (moderate default probability, ~15-20% 2-year)
• Z < 1.81: Distress zone (high default probability, >25% 2-year) → Reclassify to Path C
• For non-manufacturing: Use Z'' model (four factors, re-calibrated coefficients)

Model 2: Merton Structural Model

• Run python3 tools/merton_model.py with issuer parameters
• Equity = Call option on firm assets: E = V x N(d1) - D x e^(-rT) x N(d2)
• Solve iteratively for asset value (V) and asset volatility (sigma_V)
• Distance to Default = (ln(V/D) + (mu - 0.5 x sigma^2) x T) / (sigma x sqrt(T))
• DD > 4.0: Very low default probability (<0.5%)
• DD 2.0-4.0: Low default probability (0.5-3%)
• DD 1.0-2.0: Moderate default probability (3-15%)
• DD < 1.0: High default probability (>15%) → Reclassify to Path C

Model 3: Market-Implied Default Probability

• From CDS spreads: PD = 1 - exp(-spread / (1 - Recovery_rate))
• From bond spreads: PD_approx = Spread / LGD_assumed
• Run python3 tools/credit_spread.py for market-implied PD

Triangulation:

• If all three models agree (within 5 percentage points): High confidence in PD estimate
• If market-implied PD >> fundamental PD: Bond is oversold (potential opportunity)
• If market-implied PD << fundamental PD: Bond is overpriced (potential risk)
• If models disagree significantly: Investigate — identify what the market knows that the model doesn't

Decision Gate 3 — HY Default Assessment:

• Triangulated PD < 3% (2-year): Acceptable credit risk — proceed to relative value
• Triangulated PD 3-10%: Elevated risk — require compelling spread compensation (>200 bps above fair value)
• Triangulated PD > 10%: Reclassify to Path C — this requires distressed analysis

Phase 3: Covenant Analysis

Maintenance covenants (tested periodically, trip automatically):

• Maximum leverage ratio (Net Debt / EBITDA < X.Xx)
• Minimum interest coverage (EBITDA / Interest > X.Xx)
• Minimum liquidity (Cash + Available revolver > $XM)
• Current headroom: How close is the issuer to tripping?
• Projected headroom: Will the issuer trip under stress scenarios?

Incurrence covenants (only tested when taking an action):

• Limitation on additional debt (debt incurrence test)
• Limitation on restricted payments (dividends, buybacks)
• Limitation on asset sales
• Limitation on liens
• Change of control provisions

Covenant quality assessment:

• Tight covenants (maintenance, <15% headroom): Protect creditors but increase amendment/waiver risk
• Loose covenants (incurrence only, >30% headroom): Less protection but fewer technical defaults
• Covenant-lite (cov-lite): No maintenance covenants — lender has no early warning mechanism

EBITDA definition scrutiny:

• Review addbacks: Are they legitimate (one-time restructuring) or aggressive (recurring "non-recurring" items)?
• If adjusted EBITDA exceeds reported EBITDA by >25%: Flag as aggressive — real leverage may be higher
• Pro forma adjustments for acquisitions: Verify synergy assumptions are achievable
• Run-rate adjustments: Require evidence (signed contracts, completed initiatives)

Decision Gate 4 — Covenant Risk:

• Maintenance covenant headroom > 25%: Low covenant risk
• Maintenance covenant headroom 10-25%: Moderate risk — model stress scenarios
• Maintenance covenant headroom < 10%: High risk — covenant trip likely in downturn; negotiate or avoid
• Cov-lite with leverage > 5.0x: Structural risk — no early warning of deterioration

Phase 4: HY Relative Value

Spread per turn of leverage:

• Calculate: Spread / (Net Debt / EBITDA) for the issuer and peers
• Higher spread/turn = cheaper credit compensation per unit of risk
• Screen for: Issuers with above-average spread/turn vs. rating peers

Curve analysis:

• Short-end vs. long-end spread for the same issuer
• Steep curve = market expects credit improvement (long-end is safer)
• Flat/inverted curve = market expects deterioration (front-end reflects near-term stress)

Sector relative value:

• Compare issuer spread to sector-matched HY index
• Run python3 tools/portfolio_risk.py for portfolio-level sector exposure check

PATH C: Distressed Analysis

Goal: Identify the fulcrum security, estimate recovery, and evaluate restructuring outcomes.

Phase 1: Distress Diagnosis

Confirm distressed status through multiple signals:

Signal	Threshold	Issuer Value	Status
Bond price	<$70	$[X]
Yield spread	>1000 bps	+[X] bps
Altman Z-Score	<1.81	[X]
Distance to Default (Merton)	<1.0	[X]
CDS spread	>1000 bps	+[X] bps
Interest coverage	<1.0x	[X]x
Liquidity runway	<6 months	[X] months
Equity decline (6 months)	>50%	[X]%

If 3+ signals confirm distress: Proceed with full distressed analysis If 1-2 signals: Stress case — use Path B with downside scenarios

Phase 2: Enterprise Value Estimation

The key to distressed analysis is estimating what the reorganized company is worth:

Method 1: Going-concern (EV = Normalized EBITDA x Exit Multiple)

• Normalized EBITDA: Strip out distress-related costs, one-time items, and excess overhead
• Adjustments: Revenue run-rate post-restructuring, margin improvements from cost cuts
• Exit multiple: Based on healthy comparable companies (typically 5-7x for industrial, 8-12x for asset-light)
• Apply a distressed discount of 10-20% for execution risk

Method 2: Liquidation analysis (floor value)

• Accounts receivable: 70-90% of book value
• Inventory: 50-70% of book value (depends on perishability/specialization)
• PP&E: 30-60% of book value (fire sale discount)
• Intangibles/goodwill: $0 (typically worthless in liquidation)
• Real estate: Appraised value less 10-20% for forced sale
• Total liquidation value: Sum of adjusted asset values - Administrative costs (5-10% of total)

Method 3: Comparable distressed transactions

• EV/EBITDA multiples paid in recent restructurings in the same sector
• Recovery rates from recent defaults in the same seniority class

Run python3 tools/dcf.py with normalized projections for a DCF cross-check on going-concern value.

Decision Gate 5 — EV Confidence:

• All three methods converge (within 20%): High confidence — proceed with recovery waterfall
• Methods diverge significantly: Use range — run scenarios at low, mid, and high EV estimates
• Liquidation value > going-concern value: Likely liquidation, not reorganization — adjust recovery analysis accordingly

Phase 3: Recovery Waterfall

Map enterprise value through the priority of claims:

Enterprise Value: $[X]M

1. DIP / Super-priority claims:     $[X]M → Recovery: 100% → Remaining EV: $[X]M
2. Administrative claims:            $[X]M → Recovery: 100% → Remaining EV: $[X]M
3. First Lien Secured:              $[X]M → Recovery: [X]% → Remaining EV: $[X]M
4. Second Lien Secured:             $[X]M → Recovery: [X]% → Remaining EV: $[X]M
5. Senior Unsecured:                $[X]M → Recovery: [X]% → Remaining EV: $[X]M
6. Subordinated:                    $[X]M → Recovery: [X]% → Remaining EV: $[X]M
7. Equity:                          Recovery: [X]%

Fulcrum security identification:

• The fulcrum security is the tranche where enterprise value is exhausted
• Senior to fulcrum: Recovers at or near par (100 cents)
• The fulcrum tranche: Partial recovery (the key investment opportunity)
• Junior to fulcrum: Recovers little or nothing

Recovery benchmarks by seniority (historical averages):

• Senior secured: 55-65% (first lien), 35-45% (second lien)
• Senior unsecured: 30-45%
• Subordinated: 15-30%
• Equity: 0-5%

Run python3 tools/bond_yield.py to verify that current bond prices imply recoveries consistent with your waterfall analysis.

Phase 4: Scenario Analysis

Build probability-weighted recovery scenarios:

Scenario	Enterprise Value	Fulcrum Recovery	Probability	Weighted Recovery
Upside (operational turnaround)	$[X]M	[X] cents	[X]%	[X] cents
Base case (orderly restructuring)	$[X]M	[X] cents	[X]%	[X] cents
Downside (prolonged distress)	$[X]M	[X] cents	[X]%	[X] cents
Liquidation	$[X]M	[X] cents	[X]%	[X] cents

• Expected recovery = Sum of (Probability x Recovery) across all scenarios
• Expected return = (Expected recovery - Purchase price) / Purchase price
• Breakeven scenario: What EV is needed for the fulcrum to recover at purchase price?

Decision Gate 6 — Distressed Investment Decision:

• Expected return > 30% with >50% probability of base case or better: Attractive — size the position
• Expected return 15-30%: Marginal — require additional catalyst or entry at lower price
• Expected return < 15% or >30% liquidation probability: Pass — insufficient compensation for illiquidity and process risk
• Liquidation value > current market price of fulcrum: Floor trade — buy at below liquidation recovery

Phase 5: Restructuring Process Analysis

Out-of-court restructuring (exchange offer, amendment):

• Faster (weeks to months), cheaper, less disruptive
• Requires consent of typically 90%+ of affected class
• Holdout problem: Minority can block and extract concessions
• Common structure: Exchange old bonds for new bonds with lower face value but higher priority/coupon

Chapter 11 reorganization:

• Timeline: 12-18 months average
• DIP financing: New money with super-priority (primes all existing claims)
• Plan of Reorganization (POR): Specifies treatment of each creditor class
• Cramdown: Court can force a plan on dissenting classes if certain conditions are met
• Key dates: Bar date (claims filing), exclusivity period, plan filing, confirmation hearing

Loan-to-own strategy:

• Acquire controlling position in the fulcrum security (typically >33% to block competing plans)
• Convert debt to equity in the reorganized company
• Target: Majority ownership of post-reorg equity at a basis well below reorganized EV
• Risks: Process delays, competing plans, administrative costs, management resistance

Decision Gate 7 — Process Strategy:

• Out-of-court feasible (>90% consent likely): Participate in exchange — faster resolution, lower costs
• Chapter 11 with clear fulcrum: Buy fulcrum security — position for conversion to equity
• Competing DIP offers or priming risk: Wait for clarity — new DIP can subordinate existing claims
• Multiple competing creditor groups: Assess which group has leverage — align or avoid

---

Cross-Path Analysis: CDS and Basis Trades

Applicable to all three paths when CDS data is available.

CDS Spread Analysis

1. Market-implied default probability from CDS:

   • Hazard rate = CDS spread / (1 - Recovery_rate)
   • Cumulative PD (T years) = 1 - exp(-hazard_rate x T)
   • Run python3 tools/credit_spread.py for full CDS decomposition

2. CDS vs. agency rating comparison:

   • Map CDS-implied PD to a credit rating
   • If CDS-implied rating is significantly worse than agency rating: Market is pricing in deterioration ahead of agencies (bearish signal)
   • If CDS-implied rating is better: Market is more constructive than agencies (bullish signal)

3. CDS curve shape:

   • Normal (upward sloping): Market expects stable credit, risk increases with time
   • Flat: Elevated near-term risk but stable long-term view
   • Inverted (short-end > long-end): Market expects near-term default or distress event

CDS-Bond Basis Trade

• Basis = CDS spread - Bond Z-spread
• Negative basis (CDS < Bond): Buy bond + buy CDS protection → earn carry with credit hedge
  • Works when: Funding is cheap, bond is illiquid (wide spread includes liquidity premium)
  • Risk: Basis can widen further; counterparty risk on CDS
• Positive basis (CDS > Bond): Sell bond + sell CDS protection
  • More complex to execute; typically reflects funding stress or CDS technicals
  • Risk: If credit deteriorates, CDS losses can exceed bond gains

Run python3 tools/credit_spread.py for basis calculation and historical context.

• Relative value table — issuer vs. 5-8 peers on spread, leverage, coverage
• Covenant summary — key covenants, headroom, and stress-tested trip points
• Sensitivity matrix — spread value at different PD and recovery assumptions
• Data gaps — all missing inputs explicitly flagged with impact on confidence

---

Quality Gates & Completion Criteria

• Analysis path (A/B/C) is explicitly justified and all decision gates are documented
• Default probability is estimated using at least two independent methods
• Recovery rate is estimated with explicit seniority and asset quality rationale
• Spread is decomposed and compared to fair value (not just "the yield looks attractive")
• Relative value is assessed vs. rating-matched peers (at least 3 comparables)
• Covenants are reviewed for HY/distressed (maintenance headroom quantified)
• All tool outputs are incorporated with explicit parameters disclosed
• Risks include both idiosyncratic (company-specific) and systematic (macro/cycle) factors
• Position sizing reflects the asymmetric risk profile of credit (capped upside, large downside)

Success metric: A portfolio manager could size and execute the trade based on this analysis alone, with full understanding of the risk/reward distribution.

Escalation triggers:

• Altman Z-Score drops below 1.81 during IG analysis → immediately reclassify to Path C
• Covenant headroom falls below 10% → flag imminent breach risk and model waiver/amendment scenarios
• Market-implied PD diverges from fundamental PD by >10 percentage points → investigate the information gap
• Recovery waterfall shows equity recovery >20% → verify EV estimate is not too aggressive (common error)

---

Hard Constraints

• NEVER buy a bond because "the yield is attractive" without modeling the full distribution of outcomes including impairment
• NEVER fabricate credit spreads, bond prices, rating agency opinions, or comparable issuer data
• NEVER use a single default probability model — always triangulate with at least two methods
• NEVER assume historical average recovery rates without adjusting for issuer-specific seniority and asset quality
• ALWAYS distinguish between probability of default and loss given default — both drive expected loss
• ALWAYS check EBITDA addbacks when evaluating leverage ratios — real leverage may be higher than reported
• ALWAYS assess liquidity (cash + revolver) separately from solvency (leverage/coverage) — companies die from liquidity crises, not solvency ratios
• ALWAYS flag the asymmetric nature of credit returns: maximum upside is par; downside is default at recovery
• If the user provides only a yield or spread, require the full capital structure before making a recommendation

---

Common Pitfalls

1. Yield-chasing without modeling impairment: A 12% yield looks great until the bond defaults at 30% recovery, producing a -58% loss. Expected return = (1-PD) x Yield + PD x (Recovery - 1). → Always compute the expected return inclusive of default scenarios.

2. Ignoring liquidity in spread analysis: A bond trading at +500 bps may include +150 bps of liquidity premium that will not compress even if credit improves. → Decompose the spread; only the credit component is tradable.

3. Using leverage ratios with inflated EBITDA: Adjusted EBITDA with aggressive addbacks understates true leverage. A "4.0x levered" company with 30% addbacks is really 5.2x levered. → Scrutinize every addback; compute leverage on both reported and adjusted EBITDA.

4. Confusing seniority with security: Senior unsecured is senior in the capital structure but has no collateral. In liquidation, senior secured recovers 55%+ while senior unsecured recovers 35%. → Always map the exact position in the capital structure including collateral package.

5. Assuming ratings are timely: Rating agencies are notoriously lagging indicators. CDS spreads and equity prices move months before downgrades. → Use market-implied default probabilities alongside agency ratings.

6. Overestimating EV in distressed analysis: In distress, multiples compress, synergy buyers disappear, and management is distracted. Applying a healthy-company multiple to distressed EBITDA overstates recovery. → Use distressed transaction comps and apply a distress discount of 10-20%.

7. Ignoring intercreditor dynamics: In complex capital structures, intercreditor agreements determine which class controls the restructuring. The fulcrum security is not always the best investment — sometimes the class above the fulcrum has more negotiating leverage. → Map the intercreditor agreement before investing.

8. Neglecting DIP priming risk: New DIP financing in Chapter 11 typically gets super-priority status, subordinating all pre-petition claims. Existing secured creditors can be primed. → Monitor DIP proposals and their impact on recovery for each tranche.
