(Reuters) - PricewaterhouseCoopers said on Wednesday it agreed to buy Booz & Co., ratcheting up an aggressive move by large audit firms back into the lucrative consulting business more than 10 years after U.S. regulators tried to tease apart the two sectors.
PwC PWC.UL, one of the world's Big Four audit firms, said it will buy corporate consultancy Booz for undisclosed terms. Subject to approval by Booz's partners, the transaction was the latest in a string of similar acquisitions.
With audit revenues flattening in developed markets, the U.S.-based Big Four - also including Deloitte, KPMG and Ernst & Young - have been investing heavily in consulting, where business is growing after a recessionary slump.
With the exception of Deloitte, the trend marks a shift for the firms, which backed away from consulting around the time of the 2002 passage of the Sarbanes-Oxley law in the United States.
Approved by Congress in answer to the Enron-era accounting scandals, Sarbanes-Oxley barred firms from doing consulting work for audit clients, with some exceptions such as tax advice. The law left audit firms free to sell consulting services of all kinds to companies that were not audit clients.
PwC sold its consulting arm to IBM in 2002. In contrast, Deloitte did not follow suit - a decision that has since helped lift its revenues above those of arch-rival PwC.
With consulting's growth beckoning and Enron receding in the rear-view mirror, PwC since 2009 has made big consulting acquisitions, including Paragon Consulting Group; the commercial services consulting arm of BearingPoint; and smaller consulting firms in digital, social media and environmental areas.
$1 BLN EXPANSION PLANNED
Earlier this month, PwC said it planned to spend $1 billion growing operations worldwide in the next three years, including client offerings such as cyber-security and risk services.
Deloitte DLTE.UL has bought a slew of consulting firms, including energy consultants Altos Management Partners and AJM Petroleum Consultants; performance management advisory firm Jackson Browne; economic consultancy Access Economics; business analytics firm Oco; and sustainability specialists Clear Carbon Consulting and DOMANI Sustainability Consulting.
KPMG KPMG.UL and Ernst & Young ERNY.UL have also made several consulting acquisitions in recent years.
Booz is not related to Booz Allen Hamilton (BAH.N), the consulting firm best known for its work with the U.S. government and former employee turned secrets leaker, Edward Snowden. Booz & Co separated in 2008 from Booz Allen Hamilton.
A spokeswoman for the Public Company Accounting Oversight Board, which regulates audit firms, said the board does not need to approve the Booz transaction, "although we have an interest in it, partly because of the independence issues it raises."
Audit firms' consulting services came under scrutiny in Europe after the 2007-2009 financial crisis, when the Big Four were criticized for not warning of problems at major banks.
Critics said the auditors were too cozy with corporate clients and failed to vet thoroughly their financial statements.
The European Union in 2011 floated plans to ban the provision of consulting services by audit firms. It has since backed away from that, but the EU is still considering a cap on advisory fees an auditor can earn from a company it also audits.
