What Financial Records Are Needed to Support a Loss of Profits Claim?

A loss of profits claim may require a detailed review of the financial records available to the business. These records can help establish historical financial performance, identify relevant revenue and costs, and provide information for assessing the loss being claimed.

The documents that may be relevant will depend on the nature of the dispute, the period under consideration, the business involved, and the approach used for the loss of profits analysis. Financial statements are therefore only one part of the evidence that may need to be considered.

This guide outlines financial and related business records that may be relevant when preparing or reviewing a loss of profits claim.

Why Financial Records May Matter in a Loss of Profits Claim

A loss of profits analysis may involve comparing the financial results that actually occurred with an assessment of what might have occurred in the relevant circumstances.

Financial records can provide information about:

• Historical revenue and sales activity
• Direct and indirect costs
• Profit margins
• Business performance before the relevant event
• Changes in performance during the relevant period
• Customer activity and order volumes
• Operating capacity
• Financial trends over time

The records may also help identify assumptions that require further examination.

Financial information does not necessarily establish the amount of loss by itself. Depending on the circumstances, other evidence may also be relevant, including contracts, customer records, operational information and market data.

Core Financial Records

Annual Accounts and Management Accounts

Annual financial statements can provide an overview of a business's historical financial performance.

Depending on the period under consideration, potentially relevant records may include:

• Profit and loss accounts
• Balance sheets
• Cash flow statements
• Notes to the accounts
• Supporting accounting schedules

Management accounts may provide more frequent or detailed information than annual accounts. Monthly or quarterly management accounts may be relevant where the timing of the alleged loss is important.

These records can help establish historical revenue, expenditure and profitability over the relevant periods.

General Ledger Records

The general ledger contains accounting entries supporting the financial information recorded by a business.

A review may help identify:

• Revenue categories
• Operating expenses
• Payroll costs
• Administrative expenses
• Depreciation
• Exceptional items
• Other material accounting entries

The level of detail available in the general ledger can vary between businesses. Supporting schedules or other records may therefore be needed to understand particular entries.

Sales and Revenue Records

Sales records may be relevant where a claim concerns lost sales or reduced business activity.

Potentially relevant information may include:

• Sales invoices
• Customer orders
• Sales ledgers
• Revenue by customer
• Revenue by product or service
• Monthly sales data
• Cancelled or deferred orders

The appropriate records will depend on how the business records and reports its sales.

Reviewing sales information over time may help identify patterns before, during and after the period relevant to the claim.

Cost and Margin Information

A loss of profits analysis may require consideration of costs associated with generating the revenue said to have been lost.

Direct Costs

Direct costs may include expenses that vary with sales or production levels.

Examples can include:

• Materials
• Product purchases
• Freight and delivery costs
• Sales commissions
• Transaction fees
• Certain subcontractor costs

The treatment of these costs will depend on the circumstances of the business and the particular claim.

Indirect and Fixed Costs

Other costs may remain relatively stable over a particular period even when revenue changes.

Examples can include:

• Rent
• Certain salaries
• Insurance
• Professional fees
• Administrative costs
• Some technology and software expenses

Understanding how different costs behave might be relevant when considering the profit associated with revenue that is alleged to have been lost.

Gross Margin and Contribution Information

Historical margin information may help in examining the relationship between revenue and profit.

Depending on the business and available records, the analysis may consider:

• Gross profit margins
• Contribution margins
• Product or service-level profitability
• Changes in margins over time
• Differences between customer or business segments

Historical margins should not necessarily be assumed to apply throughout the claim period. Changes in pricing, costs, capacity and market conditions may need to be considered.

Budgets, Forecasts and Business Plans

Budgets and forecasts prepared before the relevant event may provide information about the expectations of the business at the time they were prepared.

Potentially relevant documents include:

• Annual budgets
• Monthly forecasts
• Sales forecasts
• Business plans
• Board papers
• Financial projections
• Investment plans

These records may help show what management expected before the disputed event.

A forecast does not, by itself, establish what would have happened. Its assumptions, preparation date, purpose and subsequent performance may all be relevant when considering its evidential significance.

For example, a forecast prepared before the relevant event may need to be considered alongside actual trading results and other information available at the time.

Bank Statements and Cash Records

Bank statements and other transaction records may provide supporting information about actual financial activity.

Depending on the issues in dispute, they may help with:

• Verifying particular receipts or payments
• Reconciling accounting records
• Examining the timing of transactions
• Identifying customer receipts
• Reviewing significant payments

Bank records may be useful where individual transactions require additional support or where other accounting information is incomplete.

Payroll and Staffing Records

Staffing information may be relevant where labour costs form a significant part of the business's operations.

Potential records include:

• Payroll reports
• Employee cost schedules
• Staffing levels
• Overtime records
• Contractor payments
• Recruitment records

These records may help explain changes in staffing levels and employment costs during the relevant period.

They may also provide information about whether the business had the personnel or labour capacity that would have been relevant under a particular scenario.

Customer and Contract Records

Although not strictly financial records, customer and contract documentation may provide important context for a loss of profits analysis.

Relevant documents may include:

• Customer contracts
• Purchase orders
• Sales agreements
• Renewal records
• Customer correspondence
• Order histories
• Cancellation records

Such records may help connect financial information with particular customers, transactions or commercial opportunities.

The relevance of individual documents will depend on the issues being considered.

Records Showing the Effect of the Relevant Event

Where a business alleges that an event affected its profits, records from the affected period may be relevant to understanding the financial impact.

Depending on the circumstances, these could include:

• Sales reports
• Order cancellations
• Production records
• Operational reports
• Cost records
• Internal financial reporting
• Records of additional expenditure

The appropriate records will depend on the alleged cause of the loss and the way the business operates.

Historical Records Before the Relevant Event

Records from periods before the alleged loss may provide information about previous business performance.

Depending on the circumstances, it may be relevant to consider:

• Revenue trends
• Seasonal variations
• Profit margins
• Customer concentration
• Changes in operating costs
• Previous fluctuations in performance

Historical information may provide useful context, but an earlier period is not necessarily comparable with the period under consideration. Changes in the business, market, customer base, pricing or operating conditions may affect how historical records can be interpreted.

Records From the Period After the Event

Post-event records may also provide information relevant to a loss of profits analysis.

They may show:

• Recovery in sales
• Changes in customer behaviour
• Changes in margins
• Operating capacity
• Continuing financial effects
• The timing of any recovery

Post-event performance may need to be considered carefully because subsequent results can be affected by factors unrelated to the event in dispute.

What If Financial Records Are Incomplete?

Financial records are not always complete for every period or transaction.

Records may be missing because of:

• Changes in accounting systems
• Business restructuring
• Data retention practices
• Lost documents
• Incomplete historical records
• Differences between accounting and operational systems

Where information is incomplete, other available records may provide additional information or corroboration. These might include bank statements, invoices, tax records, customer data, contracts or management information.

Alternative records should still be considered in light of their relevance, reliability and relationship to the issue being examined. The availability of another document does not necessarily resolve a gap in the underlying financial records.

Organising Records for a Loss of Profits Review

A structured document set may make it easier to identify relevant information and outstanding gaps.

A useful starting point may be to organise records into categories such as:

1. Historical financial statements
2. Management accounts
3. General ledger and trial balance information
4. Sales and customer records
5. Cost information
6. Budgets and forecasts
7. Payroll records
8. Bank and transaction records
9. Contracts and commercial documents
10. Records relating to the alleged loss

The exact requirements will vary from case to case.

Where expert evidence is being considered, the documents available for review can form part of the wider information provided with the instruction. More information about the types of matters that may be relevant to a financial expert instruction can be found on the instruct page.

Questions to Consider When Gathering Financial Records

Before providing records for a loss of profits analysis, it may be useful to consider several questions.

What Period Needs to Be Examined?

The relevant period may extend beyond the dates during which the business says it experienced a financial impact.

The appropriate period will depend on the issues being considered and the circumstances of the claim.

What Financial Information Existed Before the Event?

Contemporaneous records may provide information about expectations, historical performance and forecasts that existed before the relevant event.

Which Records Show Actual Performance?

Sales, costs, margins and other financial information may need to be considered alongside the underlying accounting records.

Which Assumptions Require Supporting Evidence?

Forecast revenue, expected margins, customer retention and other assumptions may require supporting documentation or other evidence.

Are There Gaps in the Available Records?

Identifying missing information early may help determine whether other sources of evidence are available and whether further information may be required.

How the Records Fit Into a Wider Loss of Profits Analysis

Financial records are generally considered alongside the particular issues in dispute rather than in isolation.

Depending on the circumstances, a loss of profits analysis may involve examining historical performance, the financial effect of the relevant event, costs associated with the claimed revenue, and assumptions about what might otherwise have occurred.

The expertise page provides further information about areas of financial analysis that may arise in loss of profits matters.

The wider nature of the financial evidence can also depend on the type of dispute. For example, the records relevant to a contractual loss may differ from those relevant to a business interruption or intellectual property matter. An overview of the relevant areas of work is available on the services page.

Conclusion

Financial records may form an important part of the evidence considered in a loss of profits claim. Annual accounts, management accounts, sales records, cost information, forecasts, payroll records and transaction data may all be relevant, depending on the circumstances.

Customer, contract and operational records may also provide context for the financial analysis. Where records are incomplete, other available documents may provide additional information, although their relevance and reliability may need to be considered carefully.

The appropriate records will depend on the issues in dispute, the period under consideration, the business involved and the approach used to assess the claimed loss.
