The deal that freed them reached between the United States and Iran and brokered by Algeria in January 1981 prevented the hostages from claiming any restitution from Iran due to foreign sovereign immunity and an executive agreement known as the Algiers Accords, which barred such lawsuits. After failing in the courts, the former hostages turned to Congress and won support from both Democrats and Republicans, resulting in Congress passing a bill (2015 United States Victims of State Sponsored Terrorism Act [USVSST]) in December 2015 that afforded the hostages compensation from a fund to be financed from fines imposed on companies found guilty of breaking American sanctions against Iran. The bill authorised a payment of US$10,000 for each day in captivity (per hostage) as well as a lump sum of $600,000 in compensation for each of the spouses and children of the Iran hostages. This meant that each hostage would be paid up to US$4.4 million. The first funds into the trust account from which the compensation would be paid came from a part of the $9 billion penalty paid by the Paris-based bank BNP Paribas for violating sanctions against Iran, Cuba and Sudan.
