Stock and Incentive Plan of 2010 (As Amended and Restated October 22, 2013), plan participants may deliver stock, owned by the holder for at least six months, in payment of the option price and receive credit for the fair market value of the shares on the date of delivery. The fair market value of shares delivered during the nine months ended March 31, 2015 and 2014 was immaterial. Restricted Stock Units – Time Vesting and Performance Vesting Performance vesting restricted stock units are earned pro rata each year if certain performance goals are met over a three-year period and are also subject to a service condition that requires the individual to be employed by the Company at the payment date after the three-year performance period, with the exception of retirement eligible grantees, who upon retirement are entitled to receive payment for any units that have been earned, including a prorated portion in the partially completed fiscal year in which the retirement occurs. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model. Changes in our time vesting and performance vesting restricted stock units for the nine months ended March 31, 2015 were as follows:
