AIB SETTLED CITIGROUP DISPUTE OVER RUSNAK AT FRACTION OF $872m CLAIM - AIB received only a fraction of the $872 million it had sought from Citigroup when it agreed last year to settle a 12 -year case against the US bank in relation to the John Rusnak trading scandal. The Irish Times has established that the amount received by AIB under a settlement struck in January 2016 came to less than 5% of its original claim.
