MOU 16-3 states: "This MOU will become effective on its date of signing and will remain in effect for a period of one year following [DOS] unless extended by agreement of the parties." I believe this MOU was signed in conjunction with the PWA, not on Feb 1, 2017. However, NN 17-09 states that the MOU now has a deferred elective date of 31 Jan 2018. When (and how) did that date get deferred? It should have ended in December 2017....why the extra month +?
