Overview

RSM Tenon was a United Kingdom professional-services firm that provided accounting, audit-related, tax, recovery, risk-management, financial-management and business-advisory services. It was created in December 2009 through the merger of Tenon Group and RSM Bentley Jennison, combining a publicly traded accountancy consolidator with an established regional accounting and advisory practice. The enlarged business operated under the RSM name and became part of the RSM Global network. The company's origins lay partly in Tenon Group, an early British accountancy consolidator. Tenon was established to bring independent local accountancy partnerships into a national corporate structure and was one of the first United Kingdom accountancy businesses organized as a public limited company. It listed on the Alternative Investment Market and expanded rapidly through acquisitions, including the purchase of five firms in 2001 for £60 million. The consolidator model proved difficult to integrate, however, and Tenon's share price fell sharply during the early 2000s. Audit work was initially separated through an associated partnership called Blueprint Audit because of restrictions on audit ownership by public companies; those rules were subsequently relaxed. RSM Bentley Jennison had a different history. Founded in 1984 by David Bentley and John Jennison, it developed into a sizable United Kingdom chartered-accountancy and business-advisory firm with more than 1,000 employees and fifteen offices. It joined the RSM Global network after the network's previous United Kingdom member, Robson Rhodes, merged with Grant Thornton in 2007. Before the merger with Tenon, Bentley Jennison ranked among the larger British accountancy firms. The 2009 transaction, reported at approximately £76 million, created a business with national scale and around 2,600 employees across 35 United Kingdom offices. Andy Raynor, Tenon's chief executive, initially led the combined organization, while Tony Stockdale and other senior RSM Bentley Jennison figures joined the public company's board as executive directors. The firm rationalized parts of its office network while identifying Birmingham, Bristol and Leeds as areas for expansion. In 2010, RSM Tenon moved its shares from AIM to the main market of the London Stock Exchange, becoming the first accountancy firm listed there according to the referenced material. Expansion continued with the purchase of several offices from failed consolidator Vantis in June 2010. The acquired operations had generated approximately £27 million in prior-year turnover and helped support reported growth in the year ending June 2011. RSM Tenon also received industry recognition, including National Firm of the Year at the 2011 British Accountancy Awards. The company nevertheless experienced regulatory, commercial and financial difficulties. In February 2010, the Financial Services Authority fined it £700,000 over the mis-selling of structured-finance products. In January 2012, management warned that pricing pressure and difficult economic conditions would lead to losses. Raynor and chairman Bob Morton stepped down; Adrian Martin became chairman and Chris Merry became chief executive. Results released shortly afterward included a £60 million goodwill impairment, leaving the company with a substantial half-year loss. In August 2013, RSM Tenon Group's shares were suspended and the company entered insolvent administration. Its trading subsidiaries were immediately acquired by Baker Tilly UK Holdings through a limited-liability partnership. Baker Tilly LLP later adopted the RSM UK name and was rebranded as RSM in October 2015, becoming part of the modern RSM network. That successor organization should not be confused with RSM Tenon itself, which ceased operating as the listed corporate group. Subsequent regulatory proceedings also concerned the audit of RSM Tenon's 2010/11 accounts: PwC was fined in 2017 for misconduct involving insufficient audit evidence and inadequate professional skepticism. Former finance director Russell McBurnie was later excluded from the accountancy profession for five years and fined £57,000 in connection with the company's collapse, with an additional order to contribute £825,000 toward investigative costs.

History

RSM Tenon's history combined two distinct British accountancy traditions: the acquisitive Tenon Group and the partnership-based RSM Bentley Jennison practice. Tenon was created as a corporate consolidator intended to bring independent local accountancy partnerships into one national organization. It was unusual in the United Kingdom because it was publicly owned and listed on AIM rather than being wholly owned by partners. In April 2001 it acquired five firms for £60 million and became the fifteenth-largest firm in the national accountancy rankings. Integration proved difficult, and its share price fell to 6.25 pence in 2003 after the collapse of the dot-com boom. Audit work was initially conducted separately through Blueprint Audit because public-company ownership restrictions prevented Tenon itself from undertaking the work. RSM Bentley Jennison was founded in 1984 by David Bentley and John Jennison. It expanded to more than 1,000 employees in fifteen offices and ranked fourteenth in the 2007 accountancy league table. The firm obtained a place in the RSM Global network after Robson Rhodes, the network's former British member, merged with Grant Thornton in 2007. This gave Bentley Jennison an international network connection before its combination with Tenon. In December 2009, Tenon announced a merger with RSM Bentley Jennison valued at approximately £76 million. The combined company adopted RSM branding, retained a national office presence and became one of Britain's larger accounting firms, with about 2,600 employees in 35 offices. Andy Raynor initially led the enlarged company, while Tony Stockdale and other Bentley Jennison executives joined the board. RSM Tenon subsequently acquired several Vantis offices in 2010 after Vantis entered administration. The purchase supported expansion and contributed to a reported 31% increase in turnover for the year ended June 2011. The company also pursued greater capital-market visibility. In May 2010 its shares moved from AIM to the main London Stock Exchange market, an unusual step for an accountancy firm. Regulatory and commercial pressures soon became more prominent. The Financial Services Authority fined RSM Tenon £700,000 in February 2010 over the mis-selling of structured-finance products. In early 2012 the business warned that pricing pressure and a difficult economy would produce losses. Raynor and chairman Bob Morton departed, Adrian Martin became chairman and Chris Merry became chief executive. The company then reported a half-year loss following a £60 million goodwill write-off. In August 2013, RSM Tenon Group's shares were suspended and the company entered insolvent administration. Baker Tilly UK Holdings acquired the trading subsidiaries through a limited-liability partnership, ending RSM Tenon's existence as an independent listed group. Baker Tilly LLP later rebranded as RSM UK in 2015 and then as RSM, linking the acquired operating businesses to the wider RSM network. The later RSM organization is a successor to parts of the trading business rather than the same legal corporate entity as the failed RSM Tenon group. Further scrutiny followed the collapse: PwC was fined in 2017 for audit misconduct concerning the 2010/11 accounts, while former finance director Russell McBurnie received a five-year professional exclusion, a £57,000 fine and an order to pay £825,000 toward investigative costs.
