Academy President Cheryl Boon Isaacs has spoken out about the recent controversy surrounding the Oscars this year, where the best picture winner was accidentally presented to La La Land rather than the real winner: Moonlight.

As People reports, Cheryl made it clear in an email sent out to members, saying how much they have to be proud of. She also acknowledged the mistake, writing, “We all know that the wrong envelope and the problems that ensued were caused by the failure of PwC’s accountants to follow established protocols and their delay in immediately remedying the situation. PwC has accepted full responsibility for the error. Rest assured, changes will be implemented to ensure this never happens again.”

The two accountants responsible were reportedly fired from handling the envelopes at the Oscars again due to the incident, but still remain part of the firm.

Cheryl also spoke about the Oscars host Jimmy Kimmel, praising him for his “impeccable and effortless hosting job.”

Cheryl previously spoke to The New Yorker about the incident, saying it was, “Horror. I just thought, What? What? I looked out and I saw a member of [accounting firm] Pricewaterhouse coming on the stage, and I was, like, Oh, no, what—what’s happening? What what WHAT? What could possibly . . . ? And then I just thought, Oh, my God, how does this happen? How. Does. This. Happen. And it was such a wonderful show.”
