The Role of Financial Forecasts and Management Accounts in Commercial Damages Claims

Financial forecasts and management accounts can provide relevant evidence when assessing financial loss in a commercial damages claim. They may help explain how a business was performing, what management expected to happen and how those expectations compared with subsequent results.

Their relevance will depend on the facts of the dispute and the issues within the scope of the damages expert's instruction. Neither management accounts nor forecasts necessarily provide a complete picture of the financial position or establish what would have happened in the absence of the event giving rise to the claim.

For solicitors and legal teams, understanding the distinction between these types of financial information may help when considering the evidence available for a commercial damages assessment.

What Are Management Accounts?

Management accounts are financial information prepared for internal business purposes. They may be produced monthly, quarterly or at other intervals and can provide information about matters such as:

• Revenue
• Operating costs
• Gross profit
• Operating profit
• Business units or divisions
• Cash flow
• Customer or product performance
• Budget performance

The format and level of detail can vary significantly between businesses.

Unlike statutory accounts, management accounts are generally prepared to support internal management and decision-making rather than to meet a particular external reporting requirement.

This means their content, accounting policies and level of review may differ between businesses.

What Are Financial Forecasts?

A financial forecast is a projection of expected financial performance over a future period.

Depending on the business and the circumstances, a forecast may include assumptions about:

• Future revenue
• Sales volumes
• Pricing
• Operating costs
• Staffing
• Investment
• Customer demand
• Profit margins
• Cash flow

Forecasts may be prepared for different purposes. For example, a business may produce forecasts for internal planning, financing discussions, investment decisions or particular projects.

The purpose and date of preparation can therefore be relevant when considering the evidential value of a forecast in a damages claim.

Why Can Management Accounts Be Relevant to a Damages Assessment?

Management accounts may provide information about the actual financial performance of a business during a relevant period.

For example, they may help an expert examine:

• The business's financial performance before the relevant event
• Changes in revenue or costs
• Trends in profitability
• The timing of financial changes
• Performance against previous expectations
• Differences between business divisions or products

This information may be relevant when an expert is assessing the financial consequences of an alleged breach, disruption or other event.

However, management accounts need to be considered in their wider context. A particular set of accounts may reflect accounting estimates, internal allocations or other assumptions that require further explanation.

How Can Forecasts Be Relevant to Commercial Damages?

Commercial damages calculations may involve a comparison between actual financial performance and a counterfactual position.

In appropriate cases, a forecast prepared before the relevant event may provide contemporaneous evidence of what the business expected to achieve.

For example, a pre-event forecast may contain projections for revenue, costs and profit for a period that later became relevant to the claim.

That forecast does not necessarily establish what would have happened. The expert may need to consider whether the underlying assumptions remained realistic and whether circumstances changed between the preparation of the forecast and the relevant period.

Contemporaneous Forecasts and Later Forecasts

The timing of a forecast can be an important consideration.

A forecast prepared before the event giving rise to the claim may provide evidence of expectations that existed at that time.

A forecast prepared after the event may have been influenced by information that became available later.

This does not necessarily make a later forecast irrelevant. Its significance will depend on the circumstances and the purpose for which it was prepared.

The expert may therefore need to consider when the forecast was created, what information was available at the time and whether subsequent events affected the assumptions used.

What Should Be Considered When Reviewing a Forecast?

A damages expert may need to understand the basis on which a forecast was prepared.

Relevant information may include:

The Date of Preparation

The date can help establish what information was available when the forecast was created.

The Purpose of the Forecast

A forecast prepared for internal budgeting may have a different purpose from one prepared for a lender, investor or specific business proposal.

The Person or Team Responsible

It may be relevant to understand who prepared the forecast and what information they had available.

The Underlying Assumptions

The forecast may depend on assumptions concerning revenue, pricing, costs, staffing, customer demand or other factors.

Previous Versions

Earlier versions may provide additional context where the forecast changed over time.

Actual Results

Comparing forecasts with subsequent actual results may provide information about the accuracy of previous assumptions. It does not, by itself, determine whether a particular forecast was reasonable when it was prepared.

Comparing Forecasts With Management Accounts

One potentially useful area of analysis is the relationship between forecasts and actual management accounts.

For example, an expert may be able to compare:

• Forecast revenue with actual revenue
• Forecast costs with actual costs
• Forecast margins with actual margins
• Forecast customer volumes with actual customer volumes
• Forecast business growth with subsequent performance

This may help identify where actual performance differed from earlier expectations.

However, a difference between forecast and actual performance does not necessarily demonstrate that the original forecast was inappropriate. Actual results can be affected by circumstances that were not known or reasonably anticipated when the forecast was prepared.

Changes to Forecasts Over Time

Businesses may revise their forecasts as new information becomes available.

Changes may arise because of:

• Changes in customer demand
• New contracts
• Loss of customers
• Changes in pricing
• Increased or reduced costs
• Staffing changes
• Changes in market conditions
• Operational difficulties
• Changes in business strategy

Where several versions of a forecast exist, retaining those versions may help provide a fuller picture of how expectations developed.

The relevance of each version will depend on the circumstances of the claim and the issues being considered.

The Importance of Understanding Underlying Assumptions

A forecast is built on assumptions. Those assumptions may relate to both financial and operational matters.

For example, projected revenue might depend on an expected number of customers and an assumed average transaction value.

Projected profit may then depend on assumptions about the costs associated with generating that revenue.

A damages expert may therefore need to examine the relationship between individual assumptions rather than considering forecast figures in isolation.

This can be particularly relevant where the claim depends on projected performance over an extended period.

Using Management Accounts to Understand Financial Trends

Management accounts may help an expert examine financial trends over time.

For example, a series of monthly management accounts may show whether revenue was increasing, decreasing or remaining relatively stable before the relevant event.

They may also show changes in:

• Gross margins
• Operating expenses
• Staffing costs
• Customer-related income
• Product or service performance
• Seasonal patterns

This information may provide context for assessing a claimed financial loss.

It is important, however, to consider whether the records cover a sufficiently relevant period and whether there were other events that may have influenced the financial results.

When Financial Information Is Incomplete

Commercial financial records may not always be complete or consistent.

There may be gaps in management accounts, changes in accounting systems or differences between internal reports and other financial records.

Where this occurs, the expert may need to consider alternative sources of information or make appropriate adjustments within the scope of the instruction.

Legal teams can help by identifying known gaps and explaining the source and purpose of the financial records provided.

This is particularly relevant where figures have been extracted from underlying records or subsequently adjusted for a particular purpose.

Management Accounts, Forecasts and the Counterfactual Position

In some commercial damages claims, the expert may be asked to consider a counterfactual position, meaning the financial position that might have existed if the relevant event had not occurred.

Historical management accounts and contemporaneous forecasts may form part of the evidence considered when developing such an assessment.

They are not necessarily sufficient on their own.

The expert may also need to consider other relevant evidence, which could include:

• Historical business performance
• Market information
• Customer data
• Contracts
• Pricing information
• Cost information
• Business plans
• Operational evidence
• Subsequent financial performance

The appropriate evidence will depend on the particular claim and the questions the expert has been instructed to address.

What Can Solicitors Provide to a Damages Expert?

Where financial forecasts and management accounts are relevant, a legal team may wish to consider providing:

• Available versions of relevant management accounts
• Forecasts prepared before the relevant event
• Later versions of those forecasts where relevant
• Budgets and budget revisions
• Information explaining significant changes
• Underlying financial records where available
• Relevant business plans
• Information about material contracts
• Factual evidence concerning changes in the business

The expert may not require every financial document held by the business. The relevant material will depend on the scope of the instruction and the financial issues being examined.

Questions to Consider When Reviewing Financial Forecasts

Before relying on a forecast as part of the financial evidence, legal teams may wish to consider:

• When was the forecast prepared?
• Why was it prepared?
• Who prepared it?
• What information was available at the time?
• What assumptions were used?
• Were earlier versions produced?
• Were assumptions subsequently changed?
• How did actual performance compare with the forecast?
• Were there other events that affected actual performance?
• Are the underlying financial records available?

These questions do not determine the weight that should ultimately be given to the forecast. They can, however, help identify areas that may require further factual or expert consideration.

A Practical Approach for Legal Teams

A clear record of the available financial information may help an expert understand how the business's financial position developed.

Where possible, it may be useful to identify:

1. The relevant historical management accounts
2. The forecasts that existed before the relevant event
3. Any significant revisions to those forecasts
4. The actual financial results for the relevant periods
5. The reasons for material changes in performance
6. Any significant gaps or limitations in the financial records

This can provide a useful starting point for the expert's financial analysis without treating any individual document as determinative.

Conclusion

Financial forecasts and management accounts can form part of the evidence considered in some commercial damages claims.

Management accounts may help explain actual financial performance and trends, while forecasts can provide evidence of expectations about future performance at particular points in time. Their relevance and evidential value will depend on the circumstances in which they were prepared, the assumptions on which they were based and the wider evidence available.

For legal teams, identifying the purpose, timing, assumptions and subsequent performance associated with financial records may help provide a clearer evidential picture for a damages expert.

The appropriate approach will vary between claims. A damages or quantum expert may need to consider financial records alongside factual, commercial and other relevant evidence when assessing the financial issues within the scope of the instruction.
