Couric also told People magazine in a story published Tuesday on its website that she hasn’t decided what she’s doing next. But she says she is "looking at a format that will allow me to engage in more multi-dimensional storytelling."

The Associated Press reported three weeks ago that Couric’s tenure as CBS anchor would end just short of five years in the job. Her contract expires June 4.

CBS has not set an exit date but is expected to appoint Scott Pelley of "60 Minutes" as her successor as early as next week.

Couric was unable to move the "CBS Evening News" out of third place in the ratings.
