You are just figuring out that the deal closed after the record date, wow. Not hosed at all, the insiders with G shares wanted it as well. The required time allotments for the proxy made it impossible to be a holder of record for the March dividend. You do realize the deal closed in fewer than 2 months from when it was announced, and it was a stock deal. Why don't you look at other stock deals that were announced, Coeur announced buying Paramount Gold & Silver in the middle of December, that deal isn't going to close until the middle of April.
Please do some diligence before your emotions do the typing.
