The Company’s restricted and performance-based share awards to certain employees and directors are subject to service requirements. A summary of the status of the Company’s nonvested restricted and performance-based share awards as of June 30, 2018 and changes during the six months ended June 30, 2018, is presented in the following table.

﻿ As of June 30, 2018, there was $43.5 million of total unrecognized compensation expense related to nonvested restricted and performance shares expected to vest. This compensation is expected to be recognized in expense over a weighted average period of 3.2 years. The total fair value of shares which vested during the six months ended June 30, 2018 and 2017 was $0.9 million and $10.0 million, respectively. During the six months ended June 30, 2018, the Company granted 2 6,147 performance share awards subject to a total shareholder return (“TSR”) performance metric with a grant date fair value of $51.13 per share and 2 6,147 performance shares subject to an operating earnings per share performance metric with a grant date fair value of $44.84 per share to key members of executive management. The number of performance shares subject to TSR that ultimately vest at the end of the three-year performance period, if any, will be based on the relative rank of the Company’s three-year TSR among the TSRs of a peer group of 4 3 regional banks. The fair value of the performance shares subject to TSR at the grant date was determined using a Monte Carlo simulation method. The number of performance shares subject to core earnings per share that ultimately vest will be based on the Company’s attainment of certain core earnings per share goals over the two-year performance period. The maximum number of performance shares that could vest is 200% of the target award. Compensation expense for these performance shares is recognized on a straight line basis over the three-year service period.
