Mayer Brown is a leader in developing legal solutions for the runoff market. We are exceptionally well-positioned to advise clients on the optimal management of their legacy liabilities.

The efficient management of runoff business is a critically important issue for the insurance industry in the United Kingdom, Continental Europe and the United States, particularly with the advent of Solvency II and emerging international insurance capital standards.

Mayer Brown’s runoff solutions team combines a detailed and practical knowledge of the global (re)insurance markets with restructuring and insolvency experience.

We provide “cradle to grave” advice for clients, from entering the runoff market, to managing discontinued operations, to ultimately achieving an appropriate exit strategy, including by way of:

  • the purchase and sale of runoff portfolios;
  • the outsourcing of the runoff of portfolios or of the underlying information technology operation;
  • the commutation of books of business or individual contracts; and
  • the reinsuring or retroceding of legacy liabilities by stop loss covers, adverse development cover and loss portfolio transfer arrangements.

Mayer Brown has also been at the forefront of the development of third-party risk capital arrangements for the runoff markets, including the formation of fund-backed joint ventures.
