Meaning
Specialized liability policies protect former directors and officers against claims arising from wrongful acts committed prior to a corporate acquisition or liquidation. Known in commercial practice as d&o runoff insurance, this coverage extends the discovery period of an existing directors and officers policy for a set duration, typically six years. The policy covers liabilities incurred during the operational period of the entity before the transaction closing date.
Claims asserted after the transaction completes fall under this runoff structure rather than the buyer’s ongoing insurance program. Coverage excludes post-closing acts and provides dedicated limits that cannot be depleted by ongoing operational risks of the successor entity.
Tail Liability
Transaction agreements assign indemnity obligations between target companies and acquiring entities to manage historic exposures. Purchasing d&o runoff insurance isolates historical governance liabilities, preventing post-closing claims from draining the cash reserves of the combined corporate structure. Target company directors routinely require the purchase of six-year tail coverage as a non-negotiable condition precedent in share purchase agreements.
Without this coverage, retiring board members remain personal targets for shareholder derivative suits or regulatory enforcement actions long after operational control passes to a buyer.
Premium Structure
Insurers calculate runoff policy premiums as a single upfront payment charged at closing, expressed as a percentage of the annual policy premium. Payment occurs during deal settlement, funded through transaction proceeds or target cash balances before equity distribution.
Claim Boundary
Standard runoff contracts freeze the scope of coverage to decisions made before the effective date of the corporate change in control. If a claim involves a continuous breach that spans both pre-closing and post-closing dates, insurers allocate losses between the runoff policy and the buyer’s active policy. Clear separation of board responsibilities across the closing date prevents coverage disputes between carrier syndicates.
