An insured distributed dividends from a Spanish entity to a Luxembourg parent entity and sought to rely on a double tax treaty to pay tax in Luxembourg. The insured tax risk arose if the dividends were instead deemed taxable in Spain. The policy was taken out to provide coverage in the event the Spanish Tax Authorities (STA) challenged the tax treatment of the distribution.
Tax Claim
In due course the STA initiated a tax audit, which the insured notified to insurers under the policy terms. The insured engaged with the audit and provided responses to the STA, all with the prior consent of insurers.
The STA duly assessed a liability for withholding tax, alleging that the parent lacked substance in Luxembourg. Insurers provided support for the first instance appeal, which was unsuccessful. Following this, and on the basis the insured was required to pay the alleged tax liability to continue its appeal, insurers paid an Advance Tax Payment to the insured in accordance with the policy terms.
The insured has now filed a second stage appeal in the Spanish Courts and insurers continue to pay defence costs, whilst awaiting a final determination.
Insight
Although early in its life cycle, the specific risk tax product is operating exactly as anticipated, with insurers supporting the dilligenced position by making payments of defence costs and advance tax payments.

Scenario
After closing, the Buyer discovers that there are errors in the target company’s financials. These errors include: (1) failing to accrue for costs related to annual plant maintenance; (2) improperly recognizing certain revenue in the trailing twelve months (TTM) period; and (3) overstating the account receivables balance by not writing down impaired collectability risks.
Breach and claims process
The above issues comprise typical breaches of the financial statements representation in the acquisition agreement. The language of the financial statements representation and the standard applied therein (i.e., in accordance with GAAP, industry standard, consistent with past practices, etc.) will control the analysis and claims investigation. The claims process will involve the Insurer’s financial advisor reviewing the material provided by the client’s financial advisor/counsel and then following up with questions aimed at validating breach and the corresponding loss. The challenges that arise during financial statements claims vary greatly but often relate to disagreements over how the breach impacts the buyer’s valuation model, how similar situations may have impacted the purchase price during negotiations, materiality thresholds under GAAP, whether the breach impact is recurring and/or whether the loss valuation is reliant on estimates that were not repped to in the financial statements.
Outcome
Based on our experience, should the above scenario violate the accounting standards provided in the financial statements representation, we would expect the Insurer to recognize breach and loss. Further, we would anticipate that error one (failure to accrue for costs) and error two (improper revenue recognition) would result in more than dollar for dollar loss because those losses are recurring in nature. That recurring loss would likely be based on how the deal was valued. So, for instance, if the deal was valued on an EBITDA multiple then those verified loss amounts would be subject to the same calculation. For error three, we would anticipate that the insurer might take the position that these damages should be reimbursed on a dollar-for-dollar basis, claiming that they are not recurring in nature.

Scenario
An insured acquired a target company with several material customers. Following completion, the insured became aware that one of the target’s key customers had in fact terminated its contract with the target prior to signing. The contract represented significant ongoing revenue for the target and was factored into the valuation methodology and the purchase price paid for the target.
The insured submitted its claim to the insurer and breach of the material contracts warranty was quickly established. The policy and SPA were subject to English law and loss was considered on a share-value basis. In order to quantify the loss suffered, both the insured and insurer appointed financial experts, who alongside the parties and their legal advisers considered contemporary evidence of the valuation methodology (which included a multiples basis), the recurring nature of loss given the length of the contract and how the issue would have been dealt with at the time of the transaction, had it been known. Following discussions between insured and insurer, steered by Aon, the parties reached a mutually agreeable commercial compromise and agreed to settle for an eight-figure sum.
Insight
Contemporary evidence of the valuation methodology used in a transaction can be key when advancing a claim with loss on a share value basis. Insurers and insureds will commonly instruct financial experts to consider the quantification of loss, and factors may include the recurring nature of the loss, to what extent the loss is of a type factored into the valuation methodology, how the issue would have been dealt with between the seller and a reasonable buyer had it been known at the time of the transaction as well as the value of the shares and purchase price.

Scenario
Post-completion, the insured discovered that there was a third party demand against the target, which was in litigation and where the litigation warranty was considered breached.
The insured submitted its claim to the insurer but did not provide any information or seek the insurer’s consent with regards to significant defence costs being incurred. Aon reminded the insured of the need to involve the insurer in its defence strategy, and the insured settled the third party litigation with the insurer’s involvement and consent to settlement.
Following settlement a discussion followed between insured and insurer on defence costs cover, and Aon assisted the insured in successfully claiming some of its defence costs from the insurer.
Insight
With third party demands it is important for insureds to be aware of insurers’ rights regarding settlement and prior written consent to defence costs, to ensure compliance with policy terms and to avoid curtailing the insured’s own claim.

Scenario
An insured submitted its claim notice directly to the insurer without first consulting its broker, who it copied in when submitting the notice. In its drafting of the claim notice, the insured had set out the relevant warranties considered to be breached but only as those warranties were covered under the SPA, not reflecting the seller knowledge scrapes which the insured had purchased as part of its cover under the policy.
Claims Process
Following receipt of the claim notice, the insurer raised various requests for information, including the seller’s knowledge of the issue. Aon flagged to the insured that they were not required to demonstrate seller knowledge as a result of the knowledge scrape enhancement provided under the policy, and assisted the insured in preparing its responses to the RFIs, including setting out that seller knowledge was not required. Breach of warranties was established.
Insight
The policy is the contract agreed between insured and insurer, and should be considered as the first source for the bases of warranties covered, both in relation to scrapes and also in relation to warranty qualifiers.

Loss remains concentrated in financial statements and tax warranties, but breach activity and loss are gradually spreading into a wider set of provisions, including litigation, compliance with laws and disclosure.
Financial and tax warranties still dominate the loss and notification pictures respectively, but emerging material contract disputes and a broader spread of loss across other warranty areas may indicate more focused claims notifications rather than relying on ‘sweeper’ warranties.
Breach Type
Figure 28 presents a picture that is broadly consistent with recent years where breaches of warranty and losses arise, with measured shifts rather than wholesale change. Financial statements and tax warranties continue to anchor both notifications and loss, with financial statements again standing out as a key driver of overall quantum. A relatively narrow group of financial and contractual warranties still accounts for a material share of loss, although we are beginning to see a slightly broader range of warranty areas contributing to meaningful claimed amounts.
Figure 28: Aon Data: Frequency vs Severity by Warranty (2017–2025)
Figures 29-31 show insurer data around the most commonly cited breaches of warranty, most commonly established breaches of warranty, and those warranty breaches which drive the greatest loss. Insurer data broadly aligns with Aon data at Figure 28 above reiterating the prominence of financial statement and tax claims.
Compared with last year’s data, the movement is evolutionary rather than dramatic. Warranties such as litigation, compliance with laws, and disclosure of information continue to show a steady increase of breach activity and a modest increase in their share of loss. Employment matters and several lower‑frequency lines remain smaller contributors in absolute terms, albeit with early signs of a more consistent pattern of loss emerging than was observable previously.
Stepping behind the data, our claims team is actively handling a number of material contract warranty breaches involving allegations of fraud and/or wilful misconduct, which are expected to resolve in 2026 with seven‑ or eight‑figure payments. Depending on how these matters crystallise, they may give rise to a more pronounced shift in the drivers of loss than is reflected in the current dataset.
We have examined these cases to identify any common themes or clear explanation for the apparent increase in this type of claim but have not, to date, observed any single, obvious trend. Our working hypothesis is that challenging macroeconomic conditions, coupled with uncertainty around tariffs and trading arrangements, have contributed to a more volatile environment for material contracts, in which late reductions or terminations can have a disproportionate impact on valuation.
Financial and tax‑related warranty breaches continue to drive claims, but the data is no longer as tightly concentrated, with other warranty categories beginning to feature more frequently.
