(1) We have incurred $461 million of cumulative costs associated with restructuring activities initiated prior to fiscal year 2016, which include lease exit, employee separation, and other related costs of $292 million, $116 million and $53 million, respectively. These cumulative costs have been reflected in our segment reporting as follows: $339 million in University of Phoenix, $19 million in Apollo Global, and $103 million in Other.
(2) The gross, undiscounted obligation associated with our restructuring liabilities as of May 31, 2016 was approximately $144 million, which principally represents costs for non-cancelable leases that will be paid over the respective lease terms through fiscal year 2023.
