Portfolio financing

Portfolio financing

Portfolio financing funds multiple cases through a single structure, using diversification to smooth the binary outcomes inherent in individual cases. Cross-collateralization allows gains from winners to offset losses from losers.

Why portfolios exist

For funders:

  • Variance reduction: a 15% loss rate doesn’t matter if the portfolio still returns 1.8x
  • Capital efficiency: one diligence process covers a diversified pool
  • Investor appetite: institutional capital prefers diversified risk profiles
  • Return predictability: portfolio-level returns are more modelable than single-case outcomes

For plaintiffs/law firms:

  • Relationship financing: ongoing capital availability across multiple cases
  • Better terms: portfolio economics support lower per-case pricing
  • Flexibility: draw capital as cases require rather than case-by-case negotiation

Structure

Core mechanics:

ElementTypical Terms
Committed capital$50M-$500M per portfolio
Deployment period2-3 years
Minimum cases10+ for meaningful diversification
Maximum single-case concentration10-15% of committed capital
Cross-collateralizationYes—portfolio-level return calculation
Advance rate30-60% of modeled recovery value

How cross-collateralization works:

Without cross-collateralization (case-by-case accounting):

  • Case A: $3M deployed, wins $9M → funder takes $9M
  • Case B: $3M deployed, loses → funder takes $0
  • Plaintiff gets nothing from Case A (funder already made target); absorbs full loss on Case B

With cross-collateralization (portfolio accounting):

  • Combined deployment: $6M
  • Combined recovery: $9M
  • Portfolio return calculated on blended basis
  • Losses are absorbed by gains; both parties share portfolio-level economics

Cross-collateralization benefits both parties by smoothing outcomes. The funder gets a more predictable return stream; the plaintiff/firm gets downside protection from single-case losses.

Economics

Portfolio returns are lower per-case than single-case funding—that’s the trade-off for diversification.

MetricSingle-CasePortfolio
Target MOIC (wins)2.5-4.0x1.6-2.2x blended
Target IRR25-50%+18-30%
Loss ratio10-20%8-15%
Duration2-5 years2-4 years average

Worked example

Portfolio profile:

  • 15 commercial cases
  • Total committed: $30M
  • Total deployed: $25M over 2 years
  • Average case size: $1.67M

Assumed outcomes:

  • Win rate: 85% (13 wins, 2 losses)
  • Average MOIC on wins: 2.0x
  • Average duration: 3 years

Return calculation:

ComponentCalculationAmount
Winning cases13 × $1.67M × 2.0x$43.4M
Losing cases2 × $1.67M × 0x$0
Total proceeds$43.4M
Total deployed$25M
Portfolio MOIC$43.4M / $25M1.74x
IRROver 3-year average~20%

Sensitivity analysis

Portfolio returns are sensitive to loss rate and win multiple:

Loss RateWin MOICPortfolio MOIC
10%2.0x1.80x
15%2.0x1.70x
20%2.0x1.60x
15%1.8x1.53x
15%2.2x1.87x

Illustrative pricing. See pricing disclaimer.

A 5% change in loss rate has roughly the same impact as a 0.2x change in win MOIC.

Diversification requirements

Portfolio construction is how funders manage binary case risk.

Dimensions of diversification:

DimensionTargetRationale
Case typeNo >25% in single typeContract, IP, securities, antitrust have different risk profiles
JurisdictionSpread across circuits/statesAvoid concentration in courts with unfavorable precedent
DefendantNo >15-20% single counterpartyDefendant bankruptcy impairs all claims against it
Law firmNo >40% with single firmFirm financial distress affects all cases
Resolution timingStaggered maturitiesAvoid J-curve concentration

Correlation analysis:

Even “diversified” portfolios can have hidden correlations:

Correlation RiskExampleMitigation
Same defendant5 cases against Company XDefendant concentration limits
Same legal theoryMultiple antitrust cases relying on same precedentTheory diversification
Same jurisdictionAll cases in Delaware ChanceryGeographic spread
Same judgeMultiple cases before Judge YDocket analysis
Same industryAll tech IP casesIndustry diversification

An adverse ruling on a common legal theory can impair multiple positions simultaneously. True diversification requires independence across all dimensions.

Distribution mechanics

Timing options:

ApproachHow It WorksTrade-offs
Interim distributionsProceeds distributed as cases resolveBetter LP liquidity; more administrative complexity
Pooled until wind-downAll proceeds held until portfolio maturesSimpler; worse LP liquidity
HybridInterim distributions above capital return; final true-up at wind-downBalances liquidity and simplicity

Waterfall structure:

1. Return of deployed capital (pro rata across LPs)
2. Preferred return (if any)—typically 8-10%
3. Catch-up to GP (if any)
4. Carried interest split (typically 80/20 or 75/25)

Reserve and follow-on funding

Portfolios require capital reserves beyond initial case commitments.

What reserves cover:

PurposeTypical Reserve
Cost overruns15-25% of committed capital
Case extensions5-10% for appeals, retrials
Opportunistic additions10-20% for new cases during fund life

Stress testing:

What happens if multiple cases need additional funding simultaneously?

  • Conservative portfolios maintain 25-30% of committed capital in reserve
  • Liquidity stress tests model scenarios where 3-4 cases need follow-on funding in same quarter
  • GP capital call policies should accommodate sudden funding needs

Portfolio vs. law firm facilities

Both provide diversified exposure, but the structures differ:

FactorPortfolio FinancingLaw Firm Facility
CounterpartyFunder deals with multiple plaintiffsFunder deals with one firm
RecourseNon-recourse to case outcomesLimited recourse to firm
SecurityInterest in case proceedsContingent fee receivables
ControlFunder approves each caseBorrowing base formula
PricingReturn share (equity-like)SOFR + spread (debt-like)
DurationCase-dependentStated maturity with extension

Law firm facilities are more debt-like; portfolio financing is more equity-like. Different risk/return profiles for different investor preferences.

Diligence for portfolio investments

Portfolio diligence operates at two levels: sampling individual cases and analyzing portfolio-level construction.

Case sampling

Deep dive on a representative sample (typically 20-30% of cases by value):

  • Full legal merit review on sampled cases
  • Damages analysis and recovery expectations
  • Counsel evaluation
  • Defendant ability to pay

Portfolio-level analysis

Focus AreaWhat to Assess
DiversificationDoes the portfolio actually achieve independence across dimensions?
ConcentrationAny single-case, defendant, or law firm concentration above limits?
CorrelationHidden correlations that could cause multiple losses?
Track recordHistorical win rate, MOIC, IRR by vintage
ReservesAdequate capital for overruns and follow-on funding?
Duration mixStaggered resolution timing or concentrated?

Manager evaluation

For portfolio exposure, manager selection matters as much as case selection:

  • Investment team credentials and litigation background
  • Case selection process and approval governance
  • Historical approval rate vs. win rate
  • Valuation methodology and reporting
  • GP commitment and alignment
