At March 31, 2015, 2.6 million of outstanding stock options and 0.2 million restricted shares were held by Liberty Media Corporation employees as a result of the January 2013 spin-off of Liberty Spinco, Inc. (currently known as Liberty Media Corporation), our then wholly-owned subsidiary.

In March 2015, Starz granted certain employees restricted stock units that will vest based upon the actual, cumulative Adjusted OIBDA (as defined in Note 9) achieved by Starz during a three year performance period beginning on January 1, 2015 and ending on December 31, 2017 (“Performance Period”), compared to a target cumulative Adjusted OIBDA during the Performance Period specified by the Starz compensation committee. Potential vesting of the restricted stock units ranges from a threshold of 50% of the target award if Starz’s actual three-year cumulative Adjusted OIBDA equals 90% of the targeted amount, to a maximum of 200% of the target award if Starz’s actual three-year cumulative Adjusted OIBDA equals or exceeds 120% of the targeted amount. Results between threshold, target and maximum will be interpolated on a straight line basis. Each restricted stock unit is the right to receive, in those specified circumstances, one share of Starz Series A common stock. Based upon the target for the Performance Period, the number of restricted stock units representing the threshold, target and maximum are 50,841 units, 101,681 units and 203,362 units, respectively.
