open lawsuits, before you own them.

Every open lawsuit raises three money questions in a deal: which policy answers it, how much the company still pays before and beside that policy, and who carries the rest after close.

how should we handle open litigation in insurance due diligence?

The short answer. For each open lawsuit or claim, confirm which policy responds and on what terms (trigger, notice, reservation of rights, defense inside or outside the limit, and limit left), then size what the company still pays through deductibles, retentions, exclusions, and amounts above the limit. Carry that uninsured share into the purchase agreement as a specific indemnity, escrow, or price item, because R&W insurance generally does not cover matters the buyer already knows about.

what are the key takeaways?

  • 1

    Which policy, which year.

    Check when the claim was first made and reported, or when the injury or damage happened. The policy’s trigger and notice terms decide.

  • 2

    What the company still pays.

    Retentions, defense inside the limit, reserved exclusions, and anything above the limit stay with the company.

  • 3

    Known usually means excluded.

    A disclosed lawsuit generally sits outside R&W cover. Price it, escrow it, or indemnify it.

where does the list of open matters come from?

No single document lists every open matter. Build the list from four sources and reconcile them, because each one misses something the others catch.

Four sources for the open-matter list.
SourceWhat it showsWhat it misses
Litigation disclosure scheduleWhat the seller is willing to representThreats described loosely, and anything under a materiality threshold
Currently valued loss runsReported claims with paid amounts and reserves by policy yearMatters never reported to an insurer, and claims handled entirely inside a retention
Audit inquiry letters to outside counselPending and threatened matters counsel has given substantive attentionMatters counsel never handled, since responses are limited in scope by design
Demand letters, agency charges, and customer disputesEarly claims that may become suitsAnything that lives only in email or a manager’s memory

Audit inquiry letters follow a framework the ABA adopted in 1975 that auditing standards still reproduce, and lawyers’ responses are deliberately limited. Treat them as one input, not the list. PCAOB AS 2505.

which policy responds to a lawsuit that is already open?

  • Occurrence policies, such as general liability, auto, and workers’ comp, generally respond under the policy in force when the injury or damage happened, even if the suit arrives years later. Ask for the policy for that year, not only the current one.
  • Claims-made policies, such as D&O, employment practices, professional liability, and cyber, generally look to when a claim was first made and, for claims-made-and-reported forms, when it was reported. Confirm the retroactive date, notice deadlines, prior-acts terms and any related-claims wording. An open matter may attach to an earlier policy year. A later suit may require an extended reporting period, replacement prior-acts coverage or a valid earlier notice of circumstances, depending on the form.
  • Reservation of rights. If the insurer is defending under a reservation of rights letter, read it. It names the exclusions the insurer may rely on later, and it is the most direct evidence of what may end up uninsured.
  • Defense inside or outside the limit. On some lines, defense costs reduce the limit. New York’s Regulation 107 generally prohibits policies that erode limits or deductibles with defense costs, with exceptions for lines such as D&O, E&O, and employment practices at stated minimum limits and with signed disclosure. 11 NYCRR 71.2 and 11 NYCRR 71.3. Other states differ. Where defense erodes the limit, less limit is left every month the case runs.
  • Limit left. Ask the insurer for the remaining aggregate in each affected policy year. Other paid claims may already have used part of it.

does an asset purchase change who gets the insurance for an open matter?

In a stock purchase, the target generally retains its historical policies and liabilities, but change-in-control terms can restrict coverage for acts after closing. A merger also requires checking which entity survives and how the policies treat it. In an asset purchase, the liability usually stays with the seller unless the agreement or successor-liability law moves it, and the seller’s policies usually stay with the seller too. If the buyer could end up holding the liability, it needs a route to the seller’s historical coverage.

Anti-assignment clauses are the usual obstacle, and state law varies. In 2015 the California Supreme Court held that Insurance Code section 520 bars an insurer from refusing to honor an insured’s assignment of coverage for injuries that predate the assignment, even where the policy has a consent-to-assignment clause. Fluor Corp. v. Superior Court (Cal. 2015). Do not assume the same result in another state. Have deal counsel address it in the agreement.

A comparison to read against the agreement and the policies. Not a legal conclusion.

how much of an open lawsuit does the company still pay?

The insured share is rarely the whole bill. Add up five pieces for each matter.

  1. The retention or deductible not yet satisfied, per claim and in aggregate.
  2. Defense costs inside the limit, where the policy works that way.
  3. Amounts the reservation of rights letter points toward exclusion.
  4. Exposure above the limit that is left.
  5. Internal cost: management time and disruption often remain with the company. Check whether any specific expense coverage applies rather than assuming reimbursement.

Who may satisfy a retention after a change of ownership is a wording question. In one Fifth Circuit case, a $250,000 self-insured retention was treated as satisfied when other insurers paid defense costs, because the policy did not expressly require the insured to pay it itself. Continental Casualty Co. v. North American Capacity Insurance Co. (5th Cir. 2012). Different wording can produce the opposite result. Read the retention clause for every open matter.

Open workers’ comp claims on a large deductible program carry their own obligation. The insurer handles and pays the claims and the employer reimburses it, usually backed by collateral. NAIC filing guidelines say the insurer’s obligation to pay claims is not eliminated if the employer fails to reimburse, and that ending the policy does not affect obligations for injuries before it ended. NAIC GL-1970. The reimbursement obligation and the collateral both have to be assigned in the deal.

how does open litigation show up in the deal numbers?

Accrual of loss contingencies is an accounting question for the QoE provider and auditors. The insurance input is the expected recovery and how reliable it is. For public companies, SEC staff guidance notes that the availability of insurance may be relevant to whether a contingency must be disclosed, and that the assessment should consider when recovery may be realized, whether the claim for recovery may be contested, and the financial condition of the party expected to pay. SEC Staff Accounting Bulletin Topic 5Y. Those three questions work on a private deal too.

  • Timing. When will the insurer pay, and does the company fund defense first?
  • Contest risk. Is there a reservation of rights, a denial, or a coverage suit?
  • Payer strength. Is the insurer solvent and rated? Is part of the recovery owed by a subcontractor’s insurer under an additional insured endorsement?

how should the purchase agreement handle an open lawsuit?

Common tools for known matters. Deal counsel drafts them.
ToolWhen it fitsWhat to watch
Specific indemnityThe uninsured share can be estimated and the seller will stand behind itCap, survival period, and who controls the defense
Litigation escrow or holdbackThe seller’s credit after close is uncertainRelease triggers tied to settlement, judgment, or a date
Purchase price reductionThe cost is predictable and the case will outlast any escrowDouble counting with a reserve already in working capital
Working capital or debt-like itemA reserve or unpaid retention already sits on the balance sheetAgreeing on the reserve figure
Seller keeps the liabilityAsset deals where the matter belongs to the seller’s historyAccess to the seller’s policies and cooperation on claims

R&W insurance is built for breaches nobody knew about. Matters disclosed in the schedules or known to the deal team are generally excluded, so known litigation travels through the tools above. The R&W side is in reps and warranties insurance by deal size.

Before closing, work with the broker and counsel to report claims and, where the form allows, circumstances to the appropriate insurers within the policy’s deadlines. Notice alone does not guarantee coverage or attach a later claim to that policy. Confirm the policy terms and the insurer’s position. Tail decisions are in exit-ready insurance and the D&O tail and the tail coverage glossary.

what does an open-litigation insurance review look like on one deal?

Hypothetical illustration, not a client. One row per open matter.
MatterPolicy that answersWhat the company still carriesDeal treatment
Forklift injury suit by a temporary workerCheck general liability for the injury year, workers’ comp and employers’ liability. Worker status and exclusions matterAny applicable deductible or retention, exclusions and amounts above available limitsAllocate the uninsured share after counsel and insurers confirm the position
Former manager’s wrongful termination claimEmployment practices, claims-made, reported in the prior policy year; defense inside the limit; reservation of rights on the wage claimsThe retention, the reserved wage claims, and a limit that shrinks with defense spendEscrow sized to the retention plus the reserved claims, released at settlement
Customer dispute over late shipmentsNone. Contract and pure economic loss claims usually fall outside general liabilityAll of itPrice or specific indemnity. Not an insurance item

The useful output is that table, one row per matter, attached to the insurance memo capital partners want.

good to know.

Straight answers to what deal teams ask about open litigation in insurance due diligence.

Does R&W insurance cover a lawsuit we already know about?

Generally no. Known and disclosed matters are usually excluded, so use a specific indemnity, escrow, or price adjustment for them.

Which policy pays for a suit filed after closing about something that happened before?

It depends on the trigger and policy terms. Occurrence policies generally look to when the injury or damage happened. Claims-made forms also require checking when the claim was first made, reporting deadlines, prior acts and related claims. A tail, replacement prior-acts cover or valid earlier notice may be relevant; none guarantees coverage by itself.

What is a reservation of rights letter, and why does it matter in diligence?

It is the insurer’s notice that it is defending while keeping the right to deny some or all of the claim later. It shows which parts of a matter may end up uninsured.

Are defense costs part of the policy limit?

On some lines they are. State rules differ: New York’s Regulation 107 generally bars defense from eroding limits except for listed lines at stated minimums with disclosure. Read the policy for each open matter.

In an asset deal, can the buyer use the seller’s policies for pre-close events?

Sometimes, depending on the agreement, the policy, and state law. California’s Fluor decision allows assignment of coverage for injuries that predate the assignment, but other states may differ, so counsel should address it.

Who pays the deductible on an open claim after closing?

The purchase agreement allocates it between buyer and seller, and the policy wording decides who may pay it. Settle both before closing.
