Most American charities, to preserve their tax-exempt status, have to file a Form 990 annually with the federal government, detailing some important statistics about their organization, including how much of the money they collect goes to overhead, advertising, and other expenses not directly related to their stated mission. Websites like Charity Navigator make these forms available online and also analyze and categorize charities based on the numbers in these forms.
Is there an equivalent mechanism in Israel (or in other countries, for that matter)?
Related question: If an Israeli charity has an "American friends of" offshoot in the US, the statistics for that offshoot in Form 990 only reflect the auxiliary fund-raising activities of the American offshoot, not the full activities of the parent organization, right?
