The board of seniors housing operator Brookdale Senior Living Inc. approved two changes to its corporate governance.

The company implemented proxy access, allowing a shareholder or a group of shareholders who have owned 3% of Brookdale stock for at least three years, among other requirements, to nominate directors at annual meetings. Proxy access will be available starting with the next annual meeting.

Brookdale also said it amended its certificate of incorporation and bylaws to put in place a majority voting standard in uncontested elections of directors. Shareholders will vote on this change at the upcoming 2019 annual meeting.
