How Are Lost Business Opportunities Assessed in Commercial Loss of Profits Claims

A business may claim that a commercial dispute caused it to lose an opportunity to secure a contract, retain a customer, expand into a new market or develop an existing commercial relationship. Assessing the financial impact can require more than identifying a potential sale or estimating the revenue associated with an opportunity.

A lost business opportunity may form part of a loss of profits claim, but the financial significance of that opportunity depends on the available evidence and the circumstances in which it arose. Relevant considerations may include the likelihood that the opportunity would have resulted in a transaction, the costs associated with fulfilling it, the expected profitability and the effect of other commercial factors.

For solicitors, counsel and businesses involved in commercial disputes, understanding these issues can help clarify the financial questions that may need to be examined.

This article explains how lost business opportunities may be assessed in a commercial loss claim and the factors that can affect the associated financial analysis.

What Is a Lost Business Opportunity?

A lost business opportunity generally refers to a potential commercial transaction or activity that a business says it was unable to pursue or secure because of a particular event or dispute.

Depending on the circumstances, the opportunity may involve:

• A proposed contract that was not concluded
• A customer relationship that was not established or continued
• A tender or procurement process
• An anticipated renewal or extension of an existing agreement
• A planned business expansion
• A potential distribution or supply arrangement
• A commercial project that could not proceed as expected

The existence of an opportunity does not, by itself, establish that a financial loss occurred or determine its value.

For example, a business may have received an invitation to tender for a substantial contract. The contract value may provide context, but it does not necessarily represent the profit that the business would have earned. The outcome may have depended on competing bids, the customer's requirements, the business's capacity and other commercial considerations.

The financial assessment therefore needs to distinguish between the value of a potential transaction and the profit that may reasonably be associated with it.

Distinguishing Lost Revenue From Lost Profits

One important consideration in assessing a lost business opportunity is the difference between potential revenue and potential profit.

The contract price or anticipated sales value may be a starting point for understanding the opportunity. However, delivering the relevant goods or services would ordinarily involve costs.

Depending on the business model, these costs may include:

• Materials and product purchases
• Labour and subcontractor expenses
• Distribution and delivery costs
• Sales commissions
• Additional equipment or capacity
• Project-specific overheads
• Other incremental operating expenses

The treatment of individual costs will depend on the circumstances and the financial approach adopted.

A loss of profits analysis may therefore need to consider the revenue that might have been generated alongside the costs that would have been incurred in generating it.

Where a business could have used existing capacity to undertake the work, the cost analysis may differ from a situation in which additional staff, equipment or facilities would have been required. Available financial and operational evidence may help inform this assessment.

Establishing Whether the Opportunity Was Realistic

A central question is whether the business had a sufficiently developed commercial opportunity for it to have financial significance.

The evidence required will depend on the nature of the opportunity. A signed agreement may provide different information from an initial enquiry, an informal discussion or an early-stage sales lead.

Potentially relevant evidence may include:

• Written proposals and quotations
• Customer correspondence
• Tender documents
• Draft contracts
• Records of negotiations
• Purchase orders
• Existing customer agreements
• Internal sales records
• Documents describing the proposed project

These materials may help establish the stage reached in the commercial process and the nature of the proposed transaction.

However, the existence of correspondence or a draft agreement does not necessarily demonstrate that a transaction would have proceeded. The significance of the evidence will depend on its context, including any outstanding conditions, unresolved negotiations or decisions that remained with the prospective customer.

Where several opportunities are claimed, each may need to be examined on its own facts rather than assuming that all would have resulted in completed business.

Assessing the Likelihood of a Commercial Transaction

Not every business opportunity has the same prospect of success. Some may have involved advanced negotiations, while others may have remained speculative.

The assessment may need to consider the circumstances that would have influenced whether the transaction proceeded.

The Stage of Negotiations

The stage reached in discussions may provide relevant context.

For example, an opportunity involving agreed commercial terms and a detailed project schedule may present different evidential questions from one involving only an initial expression of interest.

Even at an advanced stage, however, a transaction may remain subject to approval, due diligence, funding, contract execution or other conditions.

The Customer's Intentions and Requirements

Customer correspondence and procurement documents may provide information about the customer's requirements and intentions.

Relevant questions may include whether the customer had confirmed a need for the goods or services, whether alternative suppliers were being considered and whether the proposed transaction depended on conditions that remained unresolved.

The evidence should be considered in context rather than treating a customer's expression of interest as confirmation that a contract would have been awarded.

Competing Suppliers and Alternative Options

The presence of competing suppliers may affect the assessment of an opportunity.

In a tender process, for example, the business may have faced competition from other bidders. Relevant evidence could include tender criteria, available information about the procurement process, pricing requirements and records of the business's previous performance.

The purpose of considering these matters is to understand the commercial circumstances surrounding the opportunity. The effect of competition will depend on the evidence available and the particular transaction.

Estimating the Profit Associated With the Opportunity

Where an opportunity is sufficiently supported for financial assessment, the next question concerns the profit that might have been generated.

The analysis may involve examining anticipated revenue, relevant costs and the period over which the opportunity could have produced financial benefits.

Expected Revenue

Potential sources of information may include:

• Proposed contract prices
• Customer purchase forecasts
• Quoted rates
• Expected order volumes
• Pricing schedules
• Comparable transactions

The reliability of these figures may depend on whether they were agreed, proposed or based on internal assumptions.

For example, a quotation may establish the price offered by a business, but it does not necessarily establish the quantity of work that would have been awarded or the duration of the arrangement.

Costs of Delivering the Work

The financial analysis may need to identify costs that would have been incurred if the opportunity had proceeded.

These could include direct project costs, additional staffing, subcontracting, equipment and other expenses associated with delivering the contract.

The treatment of fixed and variable costs will depend on the circumstances. Some costs may have been incurred regardless of the opportunity, while others may have arisen only if the additional work was secured.

Relevant financial records and operational information may help inform this assessment. For further context, see the Loss of Profits Expert expertise page.

Duration and Repeat Business

Some opportunities involve a single transaction. Others may relate to a longer-term commercial relationship or a series of anticipated orders.

Where future business forms part of the claim, the assessment may need to consider the evidence supporting the anticipated duration and volume of work.

An initial contract does not necessarily establish that repeat orders, renewals or an ongoing customer relationship would have followed. Such assumptions may require separate consideration based on the commercial arrangements and available evidence.

Considering Alternative Explanations for the Loss

A lost opportunity may be affected by more than one factor. A business may have experienced a commercial dispute while also facing changes in customer demand, market conditions, pricing or its own operational circumstances.

These factors may be relevant when examining the financial consequences attributed to the disputed event.

Depending on the circumstances, the analysis may consider:

• Changes in demand for the relevant product or service
• The financial position of the prospective customer
• Competition from alternative suppliers
• Pricing or specification requirements
• Supply chain limitations
• The business's available resources
• Changes in the wider market

The relevance of each factor will depend on the particular opportunity and the issues in dispute.

The existence of an alternative explanation does not automatically determine the outcome of a claim. Equally, the timing of a failed transaction does not, on its own, establish that the disputed event caused the opportunity to be lost.

Causation and the legal basis of the claim may require consideration alongside the financial analysis.

Evidence That May Support the Financial Assessment

The available evidence can vary considerably between commercial disputes. A structured review may help identify what information exists and which assumptions require further examination.

Financial and Accounting Records

Relevant records may include management accounts, sales reports, cost schedules, customer profitability information and records of comparable transactions.

These materials may help establish historical margins, operating costs and the financial characteristics of similar work.

Operational Records

Operational information may help explain whether the business could have undertaken the proposed work.

Depending on the circumstances, this could include production schedules, staffing records, capacity information, project plans and supply arrangements.

Commercial Documentation

Contracts, tender documents, quotations, correspondence and customer records may help establish the nature and stage of the opportunity.

The financial significance of these documents will depend on their contents and the circumstances in which they were created.

Market Information

Market and industry information may provide context for pricing, demand, competition or expected business activity.

Such information should be considered in light of the specific opportunity. General market growth, for example, does not necessarily demonstrate that a particular business would have secured a particular contract.

Dealing With Uncertainty in Lost Opportunity Assessments

Some uncertainty is common when assessing a transaction that did not proceed. The business may not have completed the work, earned the anticipated revenue or incurred the associated costs.

The financial analysis may therefore involve assumptions about what might have occurred.

A careful approach distinguishes between established information and matters that remain uncertain. It may also be necessary to examine alternative scenarios where the available evidence supports more than one plausible outcome.

For example, the analysis may need to consider whether the opportunity involved a single contract, a series of orders or a possible longer-term relationship. Each scenario may involve different revenue, cost and duration assumptions.

The appropriate treatment will depend on the evidence and the issues that need to be addressed. A scenario should not be treated as established merely because it produces a particular financial result.

The Role of a Loss of Profits Expert

A forensic accountant or loss of profits expert may be instructed to examine the financial aspects of a commercial opportunity where those issues fall within the scope of the instruction.

Depending on the case, the work may involve reviewing financial records, analysing relevant costs and margins, assessing assumptions about anticipated trading activity and explaining the financial implications of different scenarios.

The scope of the work will depend on the questions referred to the expert and the information available. The financial analysis should distinguish between the underlying evidence, the assumptions adopted and the resulting calculations.

The expert's role is not necessarily to determine every legal issue arising from the dispute. Questions concerning liability, legal causation and the applicable legal test may require consideration by the legal representatives and the court or tribunal.

Preparing to Instruct an Expert on a Lost Business Opportunity

When a commercial dispute involves a potentially lost opportunity, it may be useful to identify the financial questions that require examination before preparing an expert instruction.

Depending on the circumstances, relevant information may include:

• A description of the opportunity and the proposed transaction
• The key events and relevant dates
• Available contracts, tenders and correspondence
• Financial information relating to expected revenue and costs
• Records of comparable work or transactions
• Information about capacity and operational requirements
• The assumptions that require financial assessment
• Any material gaps or limitations in the available evidence

The documents required will depend on the nature and stage of the dispute. Not every category will be relevant to every case.

The instruction page provides further information about instructing the practice.

Conclusion

Assessing a lost business opportunity in a commercial loss of profits claim requires consideration of both the commercial circumstances and the potential financial consequences.

The existence of an enquiry, proposal or tender does not necessarily establish that a transaction would have proceeded or determine the profit that might have been earned. The assessment may need to consider the stage of negotiations, customer requirements, competing suppliers, expected revenue, associated costs and the duration of the proposed business.

Financial records, commercial documents and operational evidence may help inform the analysis, although their significance will depend on the circumstances of the individual dispute.

A clear distinction between established facts, assumptions and uncertainties can help explain the basis of a financial assessment without treating a potential transaction as a completed one.
