NEW YORK CITY (AFP) - Accounting giant PricewaterhouseCoopers said on Wednesday it has reached a deal to buy business consultancy Booz & Company.

PwC did not reveal the financial terms of the deal, which will boost its advisory business.

The companies said the deal is subject to approval from Booz & Co's partner vote, scheduled for December, reported Reuters.

Booz & Co separated in 2008 from Booz Allen Hamilton, the consulting firm best known for its work with US government agencies. The two firms are no longer related.

PwC is one of the "Big Four" global accountants. The others are KPMG, Deloitte and Ernst & Young .
