KW Economics prepares lost profits analysis for commercial contract dispute cases venued in Illinois: what the loss claim consists of, the records that drive it, and a present value built to Illinois damages rules and venues. Plaintiff and defense.
In a commercial contract dispute the lost profits analysis reconstructs what the business would have earned had the other party performed: the revenue the contract would have produced less the incremental costs of earning it, over the contract's remaining term or the period the market supports. The economist builds the but-for path from the contract terms, the pre-dispute projections, and the company's history, separates incremental from fixed costs so only the lost margin is claimed, credits mitigation, and discounts future lost profits at a rate that reflects the risk of the earnings stream. Each element of the claim ties to a document so it can be tested independently.
Lost profits and related commercial damages for contract, business-tort, and business-interruption matters. The analysis builds the but-for revenue and cost path from the company's own history, its market, and the terms of the disputed relationship, links each claimed loss to the conduct at issue, addresses mitigation, and reasons through the period of loss so the damages figure answers the causation question as well as the amount.
The size of the claim depends on the contract's remaining term, the profit margin the business would have realized, and how much of the lost volume was or could have been replaced. Incremental cost treatment is the usual battleground: whether a given cost would have been avoided when the revenue disappeared changes the margin and therefore the loss. For a new venture or a contract without a performance history, the reasonableness of the projected revenue is the central dispute, and the period over which lost profits are claimed is scrutinized against the contract's terms and the market.
Illinois courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community, and separately whether the economist is qualified by training and experience and applied the method to the facts of the case. Forensic economic methods for lost earnings, worklife, and present value are published and long used, so the examination usually turns on the inputs and their support in the record.

Illinois reduces a negligence-based award by the plaintiff's share of fault and bars recovery once that share exceeds half. Prejudgment interest on a personal injury or wrongful death award runs from the filing of the action, and interest on a written instrument or a liquidated contract sum runs at the statutory rate from the date it was due. Economic damages are not subject to a general statutory limit, so the report states each loss as of a fixed date and separates past from future amounts so the interest computation can follow.
We issue the final report and provide deposition and trial testimony and rebuttal of opposing damages models.
The same four steps apply to a commercial contract dispute case venued in Illinois; the damages framework above decides which components enter the total. Establish the but-for revenue from the contract terms, the pre-dispute projections, and the business's own history. Identify the incremental costs that would have been incurred to earn that revenue so that only the lost margin is claimed. Analyze actual results after the breach to separate the effect of the breach from market conditions and other causes, and credit mitigation revenue. Bring past lost profits forward and discount future lost profits at a stated rate that reflects the risk of the earnings stream.

Forensic economic methods for lost earnings, worklife, and present value are published and long used, so the examination usually turns on the inputs and their support in the record. Commercial Contract Dispute cases venued in Illinois are heard in the Circuit Court (General jurisdiction; 25 judicial circuits across the state, including the Circuit Court of Cook County), with final appeals to the Illinois Supreme Court. Matters within federal jurisdiction proceed in the Northern District of Illinois, Central District of Illinois, and Southern District of Illinois.
Illinois reduces a negligence-based award by the plaintiff's share of fault and bars recovery once that share exceeds half. Prejudgment interest on a personal injury or wrongful death award runs from the filing of the action, and interest on a written instrument or a liquidated contract sum runs at the statutory rate from the date it was due. Economic damages are not subject to a general statutory limit, so the report states each loss as of a fixed date and separates past from future amounts so the interest computation can follow. The report presents past and future amounts separately, states every rate and table with its source, and shows the result under the alternatives the other side is likely to argue, so counsel can apply the Illinois rules to a documented figure.
