Newmont-Goldcorp: Despite Eyeing Eachother Up For Years, Courtship (Due Diligence), Engagement (Approving Deal) and Marriage (Shareholder Vote) All Happened Rapidly

All the deal history can be read in the Management Information Circular released March 7th, 2019.  However, page 62 outlines the rapidity of due diligence, magnified by the time it happened around Christmas/New Year's. 

What was the rush? Newmont CEO Goldberg's upcoming retirement?  Knowledge of an imminent Barrick bid? Something yet to be released by Goldcorp?

We are likely to find out after April 4th - shareholder vote day (writedowns have already been made by Goldcorp).
