  • Mark and Mike were experts in the UK pension aspect of Nortel, a major, complex and contentious international insolvency. The UK pension trial required 3 weeks of trial, involved hundreds of millions of pounds and, as is always the case, difficult actuarial concepts and valuations. They were highly skilled, able to distill the complexity so that the judge could focus on the relevant matters, always responsive and a privilege to work with. Mark was an excellent witness whose evidence was well received by the court. They are consummate professionals and we highly recommend them.

  • Mike has been Scheme actuary on the Moet Dior RBS for several years (I am the longstanding independent trustee and current chair of trustees). I have found Mike to be an excellent actuary/consultant with a confident approach to trustee business and meetings. He has considerable front line client experience in leading consulting firms and strong technical knowledge. He is easy to work with and able to explain complex concepts in an engaging way. He was well regarded by our Trustee Board.

  • Mike was appointed as the Fund’s actuary in early 2015. Of concern to the Trustee had been the capability of a new actuary in respect of the Asset Backed Funding Arrangement entered into at the previous valuation and the need to fully support the Trustee in its future negotiations with the sponsoring employer. Mike fully met expectations in these and all other respects. In addition to his responsibilities as actuary, Mike has led the client service teams encompassing administration, DB & DC consultancy and member communications. Throughout the time we have worked with Mike, he has always provided authoritative advice in a manner that is compliant and clear. We are sure that any future clients can be confident in his appointment.
