Anderson Anderson & Brown (AAB) has announced that John Black will retire as partner at the end of December.

Mr Black has spent over 25 years at AAB, including leading the audit division for over seven years. As well as advising on audit, assurance and financial reporting matters, he also assisted clients on acquisitions, disposals, fundraising and restructuring projects.

In 2015, Mr Black was actively involved in AAB’s first acquisition of John F Daly Associates Ltd, a specialist joint venture and contract audit firm.

In recent years, Mr Black has been instrumental in building the firm’s credentials and client base in the E&P arena, both in Aberdeen and in London.

Graeme Allan, chief executive, commented: “During his 25 years with the firm John has made an invaluable contribution to the continued success of AAB. In particular, he has played a key role in the development of both our audit and E&P teams, both of which have grown significantly in terms of clients, size and breadth of service.

“John has supported many clients through the challenges of change and business growth and has shared his experiences, passing on a wealth of knowledge to us all at AAB. We will miss John in the office day-to-day but look forward to continuing our relationship with him as a valued member of the AAB Alumni. We thank him for his huge contribution to the firm.”
