PwC was responsible for tabulating the results , preparing the envelopes , and handing them to presenters . It was called " as bad a mess-up as you could imagine . " The firm took " full responsibility " for handing the presenters the wrong envelope and apologized for the error , acknowledging that Cullinan and PwC partner Martha Ruiz did not follow protocols for correcting the error quickly .
