BEVERLY HILLS, Calif., Feb. 8, 2013 /PRNewswire/ -- This year, PwC celebrates its 79th year leading the Oscars® balloting process on behalf of the Academy of Motion Picture Arts and Sciences (the Academy). With final voting beginning today and completed ballots due on Tuesday, February 19, 2013 (by 5 p.m. PT), PwC balloting leaders Brad Oltmanns and Rick Rosas will again oversee the tabulation and will be the only two people in the world who know the identity of the Oscar® winners before the Oscars live telecast on ABC at 4 p.m. PT ( 7 p.m. ET) on Sunday, February 24, 2013. (Logo: http://photos.prnewswire.com/prnh/20100917/NY66894LOGO) PwC continues its traditional role of overseeing all aspects of the voting process: ensuring the integrity and validity of the balloting process, maintaining sole custody of all votes and tabulations, and remaining responsible for the confidentiality of the results. PwC's long-established system involves the precise tallying of every single ballot at a concealed location to maintain the utmost level of accuracy, objectivity and confidentiality. Oltmanns and Rosas lead a tight-lipped team of accountants who conduct the same ballot-counting method that they have used for decades. There has never been a single security breach in the 79 years that PwC has worked with the Academy and managed the balloting process. "It's great to be working with PwC - our trusted colleague - again, for the 79th consecutive year," said Ric Robertson, Academy COO. "We look forward to continuing the tradition of PwC leading our balloting process for many years to come." Once the votes have been submitted and tabulated by PwC, Oltmanns and Rosas memorize every winner, and two briefcases are prepared with a complete set of envelopes bearing all the Oscar winners' names. The briefcases are then brought by each of the PwC balloting leaders to the ceremony via separate, secret routes. During the live telecast, Oltmanns and Rosas remain backstage and hand each envelope to award presenters before they walk onstage.
