Explanation of Responses:

( 1 )Each share of phantom stock ("Phantom Share") is the economic equivalent of one share of PFC common stock. ( 2 )The Phantom Shares become payable in common shares, at the election of the reporting person, as follows: (a) Phantom Shares awarded in 2006 and 2011 became payable on January 2, 2020; (b) Phantom Shares awarded in 2007 became payable on January 4, 2021; (c) 90% of the Phantom Shares awarded in 2012 became payable on January 4, 2021, and the remaining 10% will become payable one year after termination as a director; (d) Phantom Shares awarded in 2008 and 2013 become payable on January 1, 2022; (e) Phantom Shares awarded in 2009 and 2010 become payable on January 1, 2023; ( 3 )(f) Phantom Shares awarded in 2014 and 2015 become payable on January 1, 2024; (g) Phantom Shares awarded in 2016, 2017, 2018, and 2019 become payable on January 1, 2025; and (h) Phantom Shares awarded in 2020 and 2021 become payable one year following termination as a director. In the event the reporting person's services as a director terminate prior to reaching any of the foregoing dates, all remaining Phantom Shares will convert to PFC common stock one year following such termination without regard to such dates. ( 4 )The ending balance di ffers from amounts previously reported because of shares acquired under a dividend reinvestment plan. ( 5 )On July 13, 2018, PFC split its common shares 2-for-1 (the "Stock Split"). The numbers included in this Form 4 have been adjusted to account for the Stock Split.
