Work-in-Process (WIP) Valuation

The process of estimating the value of legal work a firm has performed but not yet billed (in hourly practices) or the expected value of active, unresolved matters (in contingency practices), used for internal financial reporting, partner compensation calculations, credit facility borrowing-base determinations, and firm sale or merger negotiations. In hourly practices, WIP valuation is comparatively mechanical — time entered at standard or realized billing rates, adjusted for anticipated write-downs. In contingency-fee practices, WIP valuation is substantially harder and more consequential: it requires assigning a probability-weighted expected value to each active matter based on case stage, liability strength, damages range, and historical resolution data for comparable claims, since no invoice or billed amount exists to anchor the estimate. Firms and outside parties valuing a contingency docket for financing or transaction purposes often build case-level or cohort-level models that apply expected settlement value and probability of favorable resolution against each matter's stage, discounted for the case's expected remaining duration. Because contingency WIP has no observable market price until resolution, valuation methodology — and the conservatism or aggressiveness applied to it — is frequently the single largest point of negotiation between a firm and any lender, investor, or acquirer.

WIP valuation methodology determines the borrowing base for nearly every form of contingency-docket financing, so lenders typically impose their own discount schedule on a firm's internal case valuations rather than accepting the firm's own estimates at face value, particularly for early-stage matters with limited developed evidence.

In a firm sale or merger, WIP valuation is frequently the most contested diligence item because the acquiring party is effectively buying a portfolio of contingent claims whose true value will not be known for years, making outcome-model-informed valuation — benchmarking active matters against real court-record resolution data rather than the originating firm's own case assessments — an increasingly important diligence tool.
