(2)	Shares withheld for payment of tax liability
(3)	Shares acquired on vesting of restricted stock units ("RSUs").
(4)	Each PRSU represents the right to receive, following vesting, one share of MTS common stock. The resulting number of shares of MTS common stock acquired upon vesting of the PRSUs is contingent upon the achievement of pre-established performance metrics, as approved by the Company's Compensation and Leadership and Development Committee, over a two-year performance period beginning on December 3, 2014 and ending on the two year anniversary of the date of grant.
(5)	As a result of the below target performance against the specific performance goal, 642 of the 684 PRSUs originally granted vested and were settled in an equal number of shares of MTS common stock. The remaining 42 PRSUs were forfeited.
(6)	Each RSU represents the right to receive, following vesting, one share of MTS common stock.
(7)	The RSUs vest in three equal annual installments commencing on December 4, 2014.
