Actually, just by quickly searching the "interest" term in this thread, I believe it was 25.14% for everyone, not just for me.

That should have been specified in the "Notice of Distribution" email, which I received in January.  Interest comprised around 25% in my case. 

If you are still in doubt about the exact numbers and you need it eg. for tax purposes, then you should contact KCC directly.  They always replied quickly to me over email.

They should be resending the payments right now.  Lets hope it will get through for all those that got stuck previously.

Unfortunately, they are quite slow.  This is what they replied to me a few days ago: 
"We are doing a wire reissue as a batch group payment and need to wait for others to cure their instructions.  We anticipate doing another reissue in the next 6-8 weeks."

SWIFT transactions are a bit tricky and may get stuck.  It happened to me too.  KCC claimed that my bank refused to accept USD - I contacted the bank and it said they would accept it but it never came to them.

Later, KCC asked for updated instructions, with a remark it may take weeks till they resend it.  I asked about it again today and the answer was still: "We do not yet have a specific date to reattempt payments. We will let you know."

I imagine it could be similar for others that did not receive it.
