PwC 

PwC is a professional services network. It works across audit and assurance, tax and legal, deals, and consulting, and describes itself as tech-forward and people-empowered, with more than 370,000 people in 149 countries. Its member firms are separate legal entities. Public material it issues is general information rather than formal advice. The core service lines are assurance, tax, and advisory. There is no single global headquarters; among its largest offices are London and New York. The network is privately organised rather than a single listed company.
