Known as the Raleigh Entertainment and Sports Arena (or ESA) from 1999 to 2002, it was renamed the RBC Center after an extended search for a corporate sponsor. RBC Bank, the US division of the Royal Bank of Canada, acquired 20-year naming rights for a reported $80 million. On June 19, 2011, it was announced that PNC Financial Services bought US assets of RBC Bank and acquired the naming rights to the arena pending approval by the regulatory agencies. On December 15, 2011, the Centennial Authority, the landlord of the arena, approved a name change for the facility to PNC Arena. The name change officially took place on March 15, 2012. On a normal hockey day, PNC Arena has more than 400 people on duty for security and concessions.
