Portfolio concentration

De-risking the “Lumpiness Index”

A management framework for seeing how much of the next 12 months depends on a small number of uncertain case outcomes.

Make revenue concentration visible

Contingency firms can experience sharp swings in receipts because fee revenue depends on uncertain outcomes and timing. JusticeCFO uses “Lumpiness Index” as a management label for portfolio concentration: how much of a selected forecast period relies on a small number of projected fees.

It is not a published accounting ratio or industry benchmark. A firm can make it decision-useful by defining the period, ranking probability-weighted fees, and reporting the share represented by its top one, three, five, or ten matters.

  • Show both gross potential fees and probability-weighted fees
  • Separate matters likely to resolve soon from matters with long or uncertain timing
  • Stress-test the largest expected receipts at three-, six-, and twelve-month delays
  • Compare concentration by practice area, responsible team, venue, and litigation phase

Use scenarios, not false precision

Probability-Weighted Pipeline Value, or PWPV, is a JusticeCFO planning metric that multiplies a potential fee by an estimated probability of recovery. It can provide a more disciplined view than summing unadjusted case values, but it is still a model—not cash, receivables, fair value, or a guarantee.

Scenario labels such as P50 and P90 should be used only when the firm has enough history to estimate actual distributions. Otherwise, use plain-language base, delayed, and upside cases. Phase weights should come from the firm’s own resolved-case history and should be recalibrated when forecasts consistently miss.

Connect concentration to the cash plan

Official federal court data illustrates why timing deserves a downside case: for civil cases disposed during trial in the 12 months ending September 30, 2025, U.S. district courts reported a 30.7-month median from filing to disposition. That figure covers federal civil cases broadly and is not a settlement benchmark for plaintiff firms.

The operating question is whether cash on hand and usable credit can cover overhead and case-cost commitments if the largest projected fees arrive later than planned. A concentration report should therefore sit beside the firm’s liquidity floor, not apart from it.

Evaluate funding and borrowing capacity carefully

A lender may evaluate matters, historical outcomes, deployed costs, concentration, collateral, covenants, and other firm-specific information. There is no universal borrowing-base percentage for a contingency docket, and a JusticeCFO pipeline value should not be presented as a lender commitment.

Compare partner capital, a revolving facility, and non-recourse funding using their complete economics: interest or participation, fees, compounding, collateral, covenants, downside allocation, and the timing of expected cash. The cheapest stated rate may not be the lowest-cost structure after delay and risk are included.

Prepare for expense surges

Trial preparation can create concentrated spending on experts, depositions, travel, consultants, and technology. The size and timing vary by matter, so the forecast should use known budgets and commitments rather than a universal 90-day assumption.

An early-warning view compares unrestricted cash plus policy-permitted credit with overhead, scheduled case costs, and a chosen reserve. Management can then sequence spending, revisit budgets, or arrange capital before liquidity becomes urgent—without allowing a financial model to drive legal strategy or client decisions.

Measure net yield and distribution capacity

Gross recovery alone does not show the firm’s economics. Co-counsel shares, referral arrangements, direct case costs, acquisition spending, financing costs, and time to receipt all affect net yield. A referred matter with little capital exposure may be highly efficient, but describing its return as infinite is not useful for comparison.

The same discipline applies after a large fee arrives. A distribution policy can reserve the greater of a hard cash floor or a chosen number of months of forecast overhead and case costs, then consider taxes, debt obligations, and planned investment before partner distributions.
