Except as provided in Sections 3(b) and 3(c) below and to the extent not previously vested or forfeited as provided herein, the Units shall vest on a date as determined by the Committee after termination of the Performance Period (as defined below) and certification of performance by the Committee, but no later than March 15, 2019 (the “Date of Issuance”). On the Date of Issuance, the Units shall vest, and the Shares shall become issuable as determined based on the Company’s Adjusted ROA, as defined on Appendix A , as measured against a peer group, consisting of companies in the KBW Bank Sector index as of January 1, 2016, excluding custody banks in that index (the “Peer Group), over a three-year performance period beginning on January 1, 2016 and ending on December 31, 2018 (the “Performance Period”) as certified by the Committee following the end of the Performance Period. For members of the Peer Group who fail or are acquired, the Adjusted ROA through the time the independent company stops reporting GAAP financials will be frozen and serve as their final return metric for the Performance Period. Members of the Peer Group that continue to operate as independent companies but that fall out of the KBW Bank Sector index will continue to be used in the Peer Group. Members of the Peer Group as of January 1, 2016 are shown in Appendix B . Any new entrants to the KBW Bank Sector index after January 1, 2016 will not be considered members of the Peer Group for any award determination or calculation related to this Agreement. The number of Units that shall vest and the number of Shares that shall become issuable on the Date of Issuance is set forth on Appendix A . The number of Units vesting and the number of Shares that shall become issuable on the Date of Issuance shall be reduced in the event that Adjusted ROA for one or more fiscal years in the Performance Period is not positive, as provided on Appendix A . The number of Units vesting and the number of Shares that shall become issuable on the Date of Issuance shall also be subject to reduction in accordance with section 12(b) below.
