From the Reuters report:
Barnes & Noble said Parneros will not receive any severance payment and he is no longer a member of the board. Parneros, who joined the company as chief operating officer in November 2016, became its CEO in April 2017.
The company said it would begin search for a new chief executive, and a leadership group would share the responsibilities of the CEO till a suitable candidate is found.
The company’s board was advised by law firm Paul, Weiss, Rifkind, Wharton & Garrison LLP on Parneros’ removal.
