12. Event Risk: An Example October 1993 Marriott spun off its hotel management business worth 80% of its value. Before the spin-off, Marriott’s long-term book debt ratio was 2891/3644 = 79%. Almost all the debt remained with the parent (renamed Host Marriott), whose debt ratio therefore rose to 93%. Marriott’s stock price rose 13.8% and its bond prices declined by up to 30%. Bondholders sued and Marriott modified its spin-off plan.
