Gonzalez will continue to serve as an adviser until she leaves the company on May 20, the filing said.

Gonzalez had reported to former CEO Kevin Johnson, who said in March he would retire as the coffee chain faces a growing unionization drive at some of its U.S. locations.

Returning to the CEO position for the third time, Schultz on Monday suspended billions of dollars of planned share buybacks, saying he could put the cash toward employees, stores and customers.

Starbucks shares closed down 4.5% at $84.12 after falling more than 3% on Monday.

When she leaves, Gonzalez will receive at least $7.5 million in severance, prorated bonuses, equity grants and other benefits, according to the filing.
