All voting for Academy Awards is conducted by secret ballot and tabulated by the international auditing firm of PricewaterhouseCoopers. Secrecy is maintained by the auditors - the results of balloting are not revealed until the now-famous envelopes are opened on stage during the live television program. Because the Academy numbers among its members the ablest artists and craftsmen in the motion picture world, the Oscar represents the best achievements of the year in the opinion of those who themselves reside at the top of their craft.
