It would be much too difficult to try and pay based on shares because shares always being bought and sold. Most likely if any dividend is in settlement, it would be a special one time dividend to shareholders of record on that day it is announced. It would be negotiated by Collins lawyers and whoever the lower court justice is that we remand to, and then the government (FHFA & Treasury) would be involved. I dont think there is any possible way to back track for 13 years of dividends per shareholder, it would take a major accounting firm a year or more to figure out, costing too much in time and $$$
