Hmmmm..."convicted in absentia" always has an unhappy ring to it, though; fair enough, he was convicted in 1977 - although absent an effective defence and given the somewhat...abrupt...nature of Jordanian legal processes I wouldn't necessarily place overly much reliance upon the correctness of the verdict.
edit: That said, it looks rather like a Barings situation gone very badly wrong; massive bad loans to other members of the Chalabi family network and overstatement of the bank's assets by $200m - ouch! From what I can gather, it came to light when Jordan required all banks there to deposit 30% of their assets with the Central Bank to prop up the currency and Petra were unable to comply.
Fair enough.
