Several of his clients are European or American corporations encountering UK pensions for the first time.

Stuart is the co-author of a prize-winning actuarial paper (on scheme wind-ups) and has presented to the Association of Pensions Lawyers’ annual conference and on their introductory pensions course. In July 2005 he qualified as a CEDR Accredited Mediator and has presented on mediation to a joint ACA/APL meeting and scripted an accompanying role play on a scheme funding dispute.

Stuart was an early editor of “The Actuary” magazine, has marked professional examination papers and sat on the Ethics Committee of the Association of Consulting Actuaries.
