I sent Gerard a pointer to this thread early today and summarized it, asking for information. I've received several responses from him, to the effect that they used their new, more automated withdrawal processing tools for the first time on the 16th (which involves integrating PayPal's Mass Pay API into their system and introducing a way to capture bounced or otherwise not-accepted withdrawals and return them to lenders' accounts). At that time, the system sent a bunch of withdrawal requests twice, and Kiva paid out a large amount of extra (duplicate) cash to lenders who had requested withdrawals. Quoting now from Gerard:
[W]e took a two-pronged approach to try to get as much of that [money] back as we could:
1 - Ask the lenders to refund the extra payments.
2 - Ask PayPal to reverse any of the extra payments that don't get reversed by lenders.
On the 23rd, we ran a script that added the duplicate withdrawal requests to the lender’s transaction history. For lenders who had sent the extra funds back to us, we then turned around and voided those duplicate withdrawal requests to even things out (We had to put the duplicate requests in the transaction histories so that our bookkeeping would tie out).
For lenders who didn’t refund the duplicates or if the payments could not be reversed back to Kiva by PayPal, we just showed that in the lender’s transaction history. If they didn’t have enough credit to cover the extra withdrawals that were sent, then the account would be in the negative.
We’ll be going back over the next few days to reach out to lenders who have a negative balance to let them know how to bring it back up again.
He would like anyone whose account is still in the negative to send him email directly. If you do not have his email address, drop me a PM and I'll give it to you.
