The Practice
Economic loss, reconstructed.
When a career is interrupted, the loss is not a salary. It is a trajectory. We reconstruct that trajectory with the rigor a courtroom demands: past earnings, future earnings, fringe benefits, mitigation, and the present-value discount that ties it to the day of trial.
- Past and future lost earnings
- Fringe benefits, equity, deferred comp
- Mitigation, actual and imputed
- Worklife and discount-rate analysis
The Method
Three stages, documented at every turn.
Every assumption is stated. Every data source is cited. Every model is replicable. This is how a report survives Daubert and cross-examination.
02 / Model
Earnings reconstructed line by line.
Base compensation, bonus history, equity vesting, benefits. Worklife applied from BLS tables with sector adjustment. Present value discounted to trial. Every figure traceable to source.
03 / Testify
A report that reads like a brief.
Written for the trier of fact, not for other economists. Deposition and trial testimony delivered with the same plain language that opens the report.
