These donations are extracted from the Form 990 annual return for 2017 for the Soros Foundation to Promote Open Society. Form 990 is a United States Internal Revenue Service form that provides the public with financial information about a non-profit organization.
“Page” refers to the page number of the return for which the donation appears. A zero figure in the Amount column means the donation has been counted under another heading.
