Tracinda also said on Monday it is exploring options for its 56 percent stake in MGM. Tracinda said its move could result in a financial restructuring of the remainder of the casino company, which controls roughly a third of the famed Strip with properties such as Luxor, Mandalay Bay and Circus Circus.
