NOTE: The review attempted to capture the biggest 25 donations made by a company’s PAC for the 2016 cycle. In cases where there were donations of the same size immediately following the 25th largest donation, the group of donations closest to numbering 25 but above 10 was chosen. In cases where companies made fewer than 25 total donations, all were counted.
