http://www.openlylocal.com/suppliers/139961-exor-corporation-limited shows a negative summary figure, but no detail lines in the table at the foot of the page.
The negative figure seems to be an error, as it's not found in the last three months data at http://www.worcestershire.gov.uk/cms/council-and-democracy/chief-executive-unit/directorates/financial-services/over-500-supplier-payments.aspx
This was an error in the Worcestershire files. When we discovered it we deleted the transactions (but evidently forgot to update the cached values on the suppliers). We notified Worcestershire but they indicated they possibly wouldn't be changing it because that was how their accounts system output it. It's good to see they've changed that position and we'll import it as soon as possible
