Amnesty International paid its outgoing secretary general and deputy secretary general a total of about £850,000 in the year that both women resigned, the organisation's accounts show.
The UK-based organisation, which is not a charity but has an associated charitable arm, the Amnesty International UK Section Charitable Trust, said it has taken measures to ensure it never makes similar payments again.
Irene Khan, who served as secretary general until December 2009, received more than £530,000 – more than four times her previous salary – according to the most recent accounts of Amnesty International Ltd.
Her deputy, Kate Gilmore, who also left in December 2009, received more than £320,000, the accounts show.
Peter Pack, chair of Amnesty International's international executive committee, declined to comment on the nature of the agreements, but said in a statement: "Before committing to the agreement we signed with Ms Khan, we considered it very carefully and were convinced that it was in the best interest of Amnesty's work.
"The payment itself is made up of several elements, some of which dated back several years.
"This was a unique situation. None of the current employees, including the new secretary general, are on the terms that applied to Ms Khan.
"The new secretary general, with the full support of the international executive committee, has initiated a process to review our employment policies and procedures to ensure that such a situation does not happen again."
