That is correct.
On that date, the board said that all non-substantive issues should be resolved by December 14, and that the negotiating team “should report back to the Board at a conference call no later than December 16, 2018 to recommend either approval of the negotiated agreement”—clearly, the board did not consider it approved—“or to decide on next steps”.
Did that meeting ever happen? We don't have minutes of it.
